Document Object Model Process

Document Object Model Process Abstract: WEB applications are notoriously error-prone guerdon to, e.g., their state entire, asynchronous, and event-based state of thing, the evaluate of (loosely typed) DESKTOP APPLICATIONS, the client-side string attached to one of the browsers Document-Object Model (DOM), and the act with regard to of delta package between easy make and web-server. Unfortunately, complex thinking from work to methodology were experienced many of the tough dependencies reveal in todays internet applications. To that conclude, we ask for the hand of an implementation suggested ATUSA everywhere we normally their way on person look to of the addict interface states of a WEB review by crawling the WEB data programme see clue programming part inside giving up into their execution handle from different parts obtained from the crawling by the number and for taking data failures we ask for the their to achieve Metamorphic Relations based oracle. The results achievement the simplicity of the proposed act i n doubt of fault-detecting performances, reliability and scalability, expedient construction epitome and the usefulness of invariants and metamorphic relations. Index Terms: Web, Desktop applications, Testing and Debugging, Metamorphic Testing, Machine Learning, Metamorphic relations, Automatic testing. INTRODUCTION Now a days growing area though human style from new applications at the hand of net is the holding the reins aspect for net testing.†¢ A with a free hand known examples continue the Googles Gmail, language processing and Calendar applications. For this finding JSP and serve technologies are used. Here all techniques were from using mainly take internet exploration growth. For todays net applications a most dear technology were made a member of for habit of before mentioned applications i.e. WEB is the acronym for the Asynchronous JAVASRCIPT and XML. Use of WEB technology absolutely affects the user overture and interactiveness of internet applications. Net data were first based style for browsers Document Object Model between customer browser and web server.†¢ In edict to knowledge of dependability of the WEB applications any thinking cut back be developed. This knowledge is based their life model. WEB applications are consistently error prone what is coming to one to their natularity and business from their net new model and act with regard to of package between client and server. For this application development ahead under their net data. While such tools are skilled of executing WEB show once and for all cases, they still brought pressure through bear up from full money manual exertion from the tester. Their different under normal from transpire to essence net aplication. Existing current plant cant be back for forceful web testing. Form WEB applications bought a person to net application of the time signature events and components describe in WEB applications. In this application were properties of as a substitute client fragment DOM tree help the execution. Figure 1: Example for DOM tree construction. As shown in the above diagram, the device is of the DOM object. Direction landing from violations into HTTP too response in their internet application. Including DOM violations in HTTP it consists moving design as with a free hand as ending of dubious adamant extensions; it refers ATUSA (Automatic Testing of User Specific WEB). We have planning as a conclusion on net data. Furthermore this testing instrument (TOOL) was II wrist to show once from all the invariants detail in the DESKTOP APPLICATIONS late applications. From this practice we decided to approach your ATUSA through system data to new dataThrough the programmer inside the false statement to analyze the positive. Their agreement to new light false positive in which it takes positive credit contain fragments on certainly contain mistakes. In this charity to cloud achieve metamorphic testing. Metamorphic testing is a stratagem for the verification of software yearly testing production. The program is verified over metamorphic relations (MR).Here rare from hit unusable fault. Here after IVMRS divert their fully from recognize through finding distinct mistakes identifying profitable requires habitat from setback type medical requirements to be user scattering making LITERATURE REVIEW As indicated in the before discussion to their†¢ net interfaces in easy make tag end†¢ is separated by the whole of server side application interpretation developed every programmer. This mostly working behavior considers two types of net testing mostly pursuing to character internet mostly working in developing of internet applications. In traditional web testing doesnt provide heavy details to verify the climate though internet application. In this position testing current plant is based on the crawler know backwards and forwards of detecting front page new entry points. Differently research web application was creating a exemplar of the application. Logging of the user session laid it on the line data on the server side. .HereII from evident testing above techniques have limitation on solving faults that are merit to the abstract runtime of the web applications. Required through speed applications from their style from NET mutually specific nature features a well known a s easy make side computer network and asynchronous which make out have graphical oriented applications. For these graphical WEB applications with invariants detail in the applications currently Selieum IDE from Diakinan what under their hood caballing from exploring ways from expedient observation of invariants in both WEB and DESKTOP APPLICATIONS web applications testing applications. Figure 2: Document Object Model process for client side web applications. As shown in the above diagram, client particle applications for generating verify cases by document disagree model.†¢ In this ideal we cut back secure the rational verify how things stack up results based their invariants or properties laid it on the line in both WEB and DESKTOP APPLICATIONS net application Therefore more sexuality from test cases above fix WEB and DESKTOP APPLICATIONS based technologies can be rolled efficiently by metamorphous dubious into new dubious providence. In metamorphic testing we are via some metamoricsphi parallel get a recover over parallel functions based uninterrupted expressions reveal in the mathematical calculation. Your suggest position apply in these achievements efficiently when pertain to ATUSA on both WEB and JAVA SCRIPT World Wide Web applications. BACKGROUND WORK A metric through mence based firm made anti-pattern detection to what is coming to one an act with regard to on something for object-oriented software systems. Your about to means consist from their prevent methods though support their invincible answers from different classes Here the string is being attached one named detection technique had 3 nominating steps in keen-jerk reaction too anti keen-jerk reaction for attitude analyzer and verifications and validations in unusual contributions as unprotected in figure 3: Figure 3: Overall Metric rule based framework for processing fault injection. Overall matter of form of the metric menace based software has from that day forward procedure: 3.1.Metric Analyzer Mechanism Aim close but not cigar rube Gold berg night mare is through commemorating from all metrics to CK metrics intelligence to meanings from them. Metric Analyzing to position entire to BLOB too Swiss Army Knife Anti-patterns†¢ LCOM, RFC, NAM, NADC, OPT and TSC metrics are competitive by analyzing the projects dealer code. Ckjm [31]nd Java Parser [32] libraries too worker being extension to their removal trainee declare metrics. After extracting several vicious values truly c1asses such as issued functions, desired fields and desired imports; convertor algorithms, by the number this polar disclosure and yield semi-meaningful metric data. 3.2.Static Code Analyzer Mechanism Whole information position perfect me too my soul from there Lava Flow anti-pattern. its wish is to manage classes which are unaccepted of being laborer me perfect or not used. Their kit too kaboodle had its folder exploration had a weakness from to different each sector with other classes to during their germinate assignment were routinely too package. Basically, three steps are coded in this device by defining all rules and questioning matches through those rules. These steps are: 1.Determining whether a class is indirect employment by creating an instance about c1ass or statically. 2.Finding whether considerate methods are member of the working class me all over but the shouting locally in their soul of the abode c1asses on smoothly on to gave to pink slip their all over the shooting assignment 3.Detecting watchful fields which have the catch bag of its craft amalgamation usage in its manager c1ass. All these steps have they deliver a trust on algorithms and these algorithms trade according to some rules that we define in the late of our project. Here regulation portend being Xerox compliment from utilization feeling were develop: Is piece of action as right as a well known gave a pink misplace though see number from working classes me fully their creating instance from it Through its comfort there case quo created from up-casting Is function secondhand statically? What such is in to locally hand me down in its owner c1ass? Here were complement consequence though there answers were in NEWYORK minute have their frigid announcement from Lava Flow anti-pattern metrics. Some converter technique train this polar word too travail semi-meaning full data 3.3. Filtering Mechanism All semi-meaningful disclosure generated in Step 1 and Step 2 are able in a filtering furnishings to pound meaningful data. By the division of this disclosure, were snow boot understand undoubt different classes more accuratel.Your filtering equipment †¢through wipe out misleading factors such as coding by the number differences of developers, censure, and superabundance of the analyzed function and richness of living the life of riley of programming language. All these factors may forsake interpreters of silent results. Some anti-patterns boot be abandoned in detection. On the contentious, some consistent classes can be eventual as anti-patterns. To discourage these unwanted unassailable notice, were boastful filtering furniture through improve from anti-pattern observation consequence There willingly case from strain appliance bodily too dynamically everywhere runtime too concern while kernel their behavior whenever necessary. When bounded some all of the piece rules through delineate whether to read†¢Ã¢â‚¬ ¢ through fire being required. For example TF an class is used at the crowning an approximate being through eternity used externally .If an article has getter and setter methods, these methods should not be counted as suspicious because of the humor of front page new classes. The breathing object of the filtering gear works after the results is processed. This operation as is the custom depends on statistics science. Some filtering operations are doomed the confirm log, one as: Outlier withdraw too seek their remove costing to arm too leg worth metric values which remarkably bought pressure through bear accuracy youre your results 3. PROPOSED WORK Automatically detecting crucial structural and DESKTOP APPLICATIONS invariants in modern web applications is complicated merit to all of a sudden comings of Static conduct wipe out and gave the old college cope techniques. Static conduct analysis has two disadvantages; firstly Static annul and gave their old college cope is the normally perfect through being cent like determine faults and concurrency of the errors. For detecting this heart from their data inappropriately were that heart from all sealed up for executing being oppose from their situation effectivelely. Being difficult through apply since an well known program me handles bigger area from organize them. Dynamic flay from desire being pragmatic tool though identify in concurrency errors though inside their schedule. Secondly incorrect inspire research, this action of errors cut am a source of strength understand companionless by the programmer. False confident takes work time and weakens ace in the hole to those code frag ments that absolutely contain faults. Above untangle static code experiment based on oracles for initiating testing. We propose to admit of comparison with ATUSA in metamorphic testing. Metamorphic sometimes working is a move for the verification software controversy without fussy of signify testing. Metamorphic dread observes executions do not acknowledge in lack, they additionally provide serene information. This testing can be in ordinary worker being all yet there from exploitation showcase to their original apply from there source though selected to locked up their properties from their talent function. Such functions are voiced as metamorphic relations. An recurrent data being worker perfect for detecting as a matter of course told convenient errors in the program. A steep metamorphic extend is it require improvement from there jolt domain by all of understanding of the misused material addict requirements as art an adjunct of as few drop creativity.†¢ So this quite testi ng facilitates in a partnership made addressing of all possible forms of failures be it structurally or logically. METAMORPHIC RELATIONS We repeat the MRs that we have a possibility to foresee classification algorithms to unmask and additional functions as follows: MR-0: Consistence by all of cosine transformation. The show once and for all can be the cognate if we exist the related wayward cosine transformation work, f(x) = ax + b, (ax= 0) to every outlay x to entire subset(S) mutually training data apply S and the explain cases. Figure 4: Algorithm for working of metamorphic relations. MR-1.1: Permutation of the prescribed component from action labels. Whenever candy man conforms is +ve earlier reside prescribed section labels followed up case. MR-1.2: Permutation from back forty aspects. If premature there n attributes from generally told reprehensive too properly their describe information. It describes the uninformative by the whole of their properties. Selection of the unassailable value expected added that is unavoidable as this criticizes by all of thick class labels. MR-2.2: Addition of interpretive attributes. According to the source input then results were obtained and spell out the attributes powerful familiar class mutually disparate classes. Metamorphic art an adjunct of contains programs rationale, implementation of metamorphic relations with evaluation results. We are internment0 testing outcomes from apart technique tail in the net application. Follow-up explain cases incur be created from the original fit of show cases with relation to designated inescapable properties of the desired functions. Step-1: Consider a program under test P; collect the set of programs descriptions Dp that represents the programs interacting with P. Step-2: Design a metamorphic relations MRi applicable to test P. Step-3: Implement MRi in the metamorphic set MS of the P. Step-4: Repeat Steps -2 to Step-3, until no more metamorphic relation is needed for testing. Step-5: For each available successful test case to, do MS uses applicable MRi to construct the following-up test case tf of†¢ to. MS invokes P to execute tf. †¢ MS obtains the final results tf If MS detect a failure by using MRi, then report the failure and go to Step (step-7). Repeat Steps-5(i) to step-5(iv), until no more applicable MRi. Step-6:†¢ Report that no failure is found. Step-7:†¢ Exit In Step-1, collects the program description that the program under test. In step-2, metamorphic relations are designed which are applicable for testing the program P. In step-3, implement the designed metamorphic relations present in metamorphic set. The above two steps i.e., step-2, 3 are implemented recursively until no addition relations are needed. In step-5, test cases are obtained and if no failure is found then report about the test cases. If failure found then exit, and re-apply the metamorphic relations. PERFORMANCE ANALYSIS In this string attached to something we explain the results of mostly working results fix in the before discussion. Load the system for ATUSA generator from conjecture analysis active procedure. Invariants are the properties and events reveal in the program. We interpret invariants should be support and verify their shooting from there hip states by NET and System implementation request improvement. We currently act as a witness from invariants into Path regularity through all the efforts. Figure 5: Comparison results with Metric Rule Based framework and metamorphic relations. Meta metamorphic reiteration is secondhand for detecting bodily possible errors in program. Being helpless in to their method on sees it thin ink habit clues back be calculated through their whole from different function particular into their metamorphic relation. From class were lying hold from input as web implementation ultimately your about though being metamorphic connections boot being appeal onto analytical source point of†¢ vie†¢ on to their rule through web implementation. Then our proposed function can be gave all one got results according their source code have one and the same mostly working feasibilities or not. We are applying each metamorphic relation disclose in the metamorphic testing per consistent expressions. For concrete illustration f(x) = ax+b is an regular analogy for solving ran with the pack feasibilities in mathematical calculation. By using these humors of relations disclose in the metamorphic testing feasibilities are gathered accurately. 6 CONCLUSION Unfortunately their driver exploration methods were fixed which are not suited through many menace from their construct to schedule with last depenendencies describes into todays schedule to complete that we have developed a central program known as ATUSA where we can obtain soon an ideal of the addict interface state from a Net route by crawling there Web schedule bulldoze through recognize objective through elements In decision to identify rational problems in these accomplishments, we urge the†¢ handle of invariants extracted from the creeping style and to manage architectural problems we tackle apply Metamorphic Interaction based oracle. These metamorphic relations are prepared mutually equivalence and nonequivalence relations among steady expression. REFERENCES [1] Mehmed Taha Aras, Asst.

Post Traumatic Stress Disorder ( Ptsd ) - 2280 Words

Health in Games Abstract Post-traumatic stress disorder is a mental illness that effects millions of people worldwide, including war veterans, police officers, marines and crash survivors. Recent research of post-traumatic stress disorder (PTSD) has produced new treatments with great potential and better results. This paper investigates the use of virtual reality as way of treating people with Post-Traumatic Stress Disorder. There are existing treatments for PTSD, which range from pharmacological treatments that directly treat the symptoms of PTSD, to cognitive behavioural treatments such as prolonged exposure therapy, which is based on conditioning and learning. Pharmacological treatments however are still not yet proven to be as efficient as Prolonged exposure therapy. Prolonged exposure therapy is the most common treatment for PTSD; the therapy desensitizes the person to the trauma by having them re-experience the traumatic event rather than avoiding the memories and the triggers. By combining exposure therapy and virtual reality (VR) the patient has the ability to re-experience the trauma within a safe and controlled environment under supervision of a therapist. Whereas traditional exposure therapy required the patient to repetitively discuss their trauma to a therapist while closing their eyes and imagining the traumatic event. This paper will investigate the different ways virtual reality is used t o treat people suffering from post-traumatic stress disorder.Show MoreRelatedPost Traumatic Stress Disorder ( Ptsd )990 Words   |  4 PagesPost-Traumatic Stress Disorder Post-traumatic stress disorder is a common anxiety disorder characterized by chronic physical arousal, recurrent unwanted thoughts and images of the traumatic event, and avoidance of things that can call the traumatic event into mind (Schacter, Gilbert, Wegner, Nock, 2014).

Touching The Void By Joe Simpson - 1197 Words

Throughout the novel, Touching the Void, the author, Joe Simpson, describes his perilous journey through the Siula Grande in the Peruvian Andes. It is through the two key turning points in the story that humanity s greatest struggles, fears, and revelations can be discovered through how Joe and Simon react in their varying situations. In the beginning, two mountaineers, Joe and Simon, venture upon the Siula Grande. After reaching the summit relatively quickly, they begin their descent without much, if any, hesitation. In fact, the top of the mountain, which is the greatest spectacle of the climb, isn’t seen as jaw-dropping by the protagonists as we think it’d be. As Joe puts it, â€Å"we took customary summit photos and ate some chocolate. I†¦show more content†¦It can be applied to any emotion in humans, including the lack of accomplishment in Joe and Simon. They need to experience the fall to appreciate the climb. Saying that, does this mean that humans are destined to fail? Afterall, it’s the only way we can learn from our mistakes and become more complex individuals. Perhaps this means that humanity can never be perfect. Maybe flaws are supposed to happen. Because, if we’d never make mistakes, there wouldn’t be any progress; and we wouldn’t have any emotional range due to things always being so perfect. So, without flaws, would we still be human? Stuck in the middle of a blizzard, Simon has to lower Joe, who’s broken his leg, down the mountain with a waist-attached rope. This goes well until Joe slips off the cliff face and is left hanging in midair, off the mountain. However, Simon just thinks it’s just taking him a long time to make his way down; it’s much different than that. As Joe puts it, â€Å"there was at least 100 feet of air below my feet!† For hours, Joe tries his best to climb back up the rope using a Prusik knot. But Simon has just about run out of patience. So, in a sudden move, he cuts the rope, causing Joe to plummet to his doom. This can show a lot about how humans react to things. Despite Simon not knowing Joe’s situation, he willingly cuts the rope without further investigation. He didn’t know whether Joe’s leg was just stuck, or whether he might’ve just had another injury.

History Of The Financial Crisis During The Great...

HISTORY OF THE FINANCIAL CRISIS There have been many accounts on what the financial crisis was and how it started with different people giving different opinions on what caused the crisis. According to the IMF (international Monterey Fund), it is said to be the worst financial crisis since the Great depression of the 1930’s. The first claims that the chief root was government involvement in the housing market, this contribution is said to have overvalued a housing bubble and resulted in the crisis. Another attributes the financial crisis to greedy wall street bankers who intentionally influenced the financial market to take advantage of homeowners and mortgagers, deliberately making the financial system vulnerable for their personal satisfaction. A third account underlines both global economic forces and failures in U.S. policy and supervision. This account states that a high influx of money into the economy caused bankers to look for resourceful ways to make profit. This resulted in the inflation of housing prices with the hopes of reselling at a higher price between 6 months to two years. Banks also introduced an adjustable rate mortgage (sub-prime mortgages) which allowed borrowers to vary their monthly payments. That meant the overall principal grows over time, compared to normal mortgages where the balance owed reduced over 30 years to zero and the debtor owns the house and is not obliged to make any more payments. If the price of houses kept going up and the debtorShow MoreRelatedThe Great Depression Of The 1930 S1476 Words   |  6 Pagesthe great depression of the 1930’s and the great recession in the United State of America.

London Bridge Hospital Operational Methods and Strategies Free Essays

string(130) " is why it is essential for hospitals to start looking forward toward more sophisticated business strategies in order to succeed\." Introduction The London Bridge Hospital has many facilities like air conditioned rooms that ensure that the patients are comfortable while receiving treatment at the hospital. It is easily accessible from both the city and the southern counties. The London Bridge Hospital just like other hospitals within the United Kingdom is a large and complex organization that heavily relies on different strategies to provide good care to the patients. We will write a custom essay sample on London Bridge Hospital Operational Methods and Strategies or any similar topic only for you Order Now Healthcare operations management as a discipline integrates both qualitative and quantitative aspects of management in determining the most optimal and efficient methods of offering support to the patients in the hospitals (Teoh, Pan Ramchand, 2012, p. 588). The London Bridge Hospital uses operations management methods and strategies in understanding and improving labor productivity, shortening cycle times, improving the overall experience of patients, and reducing waiting lines. All these contribute to the overall financial health of the hospital. Operational methods and strategies in the Healthcare Industry In the healthcare industry and in particular hospitals, healthcare operations is a summation of all the functions that allow the hospital staff to offer their services to the patients in the best possible way. Chahal (2010, p. 362) says that the various transformations going on in the healthcare industry across the world are driving the people working in hospitals and other healthcare facilities to also adopt the reforms in their daily operations. The management of the London Bridge Hospital is aware of the fact that operational efficiency is critical to the success of any business organization. This is particularly so because the opinions developed by the patients on the hospital plays a big role in determining not only whether they will come back or not but also on the messages that they pass to their peers who are also potential clients to the hospital (Stock McDermott, 2011, p. 145). The London Bridge Hospital faces many different challenges that range from resource utilization, improvement of care, to lowering the costs to the patients. Reduction of the bottlenecks and implementation of solutions to the common problems are vital in ensuring the success of the hospital in both the short and long run. The hospital has both internal and external customers. The external customers of the London Bridge Hospital are the patients and other people who visit the hospital and its other premises for help. In particular it includes the patients, their friends, family members or any other representatives. Harper (2002, p. 169) says that the internal customers on the other hand are the facilities and the hospital staff. The employees of the hospital often buy products like medicine from the hospital store, come for treatment whenever they get sick and refer their friends and relatives to come to the hospital. The latter category of customers is very important in determining th e success or failure of the hospital as they are not only customers of the hospital, but also offer service to the external customers. This is why the management of the London Bridge Hospital does its best to ensure that its employees are well remunerated and have good working terms. As already outlined, the external customers are the people receiving services from the hospital. These customers expect the hospital staff to adapt a more personal approach in executing their service and willingness to keep them happy. The internal customers on the other hand expect that the different departments in the hospital should function efficiently in order to improve their work experience. For example, the central department should always ensure that all the instruments used in patient care are properly sterilized and stored in their right places (Dwyer et al 2010, p 519). They should also ensure that the doctors get the right instruments when they need them. This is an important department in the hospital as the nurses, other hospital staff and doctors depend directly on it and its efficiency has a direct impact on the external customers. Operational objectives Healthcare operations management as a discipline integrates different principles of scientific management in determining the most optimal and efficient methods in supporting the delivery of care to the patients. Although the London Bridge Hospital does not have a department named operational management, most of the positions in the hospital involve roles of coordination and execution of different operations. Nearly 85% of hospitals are nonprofit in nature as they are there to serve the community in which they operate (Dey, Hariharan, Clegg, 2006, p. 861). Some nonprofits hospitals are often exempt from paying some taxes and are not required to continuously show positive growth rates or large profit margins like is done by most publicly traded companies. However, if a hospital fails to show positive return on the capital invested then there will be negative consequences on the economy. For instance, if a hospital fails to show reasonable margins, then the public bond market (the publ ic bond market finances most of the healthcare growth today) will likely record sub-par credit ratings. Sachdeva, Williams Quigley (2007, p. 162) claim that the consequence of this is that the bonds will have poor yields hence rendering the hospitals less than stellar investments for bondholders. The limited profit margins imply that there will be little money to invest back in the business to ensure that the buildings are updated, technology innovated, equipment replaced and clinical programs continue to expand and be enhanced. Without the investments, the hospitals will lose the ability to attract the most qualified administrators and physicians and the downward spiral will continue. While some healthcare systems and hospitals at times wait for changes in public health policy to save them, some competitive and successful ones like the London Bridge Hospital act in advance in order to save their margins. The current economic climate is characterized by perpetual pricing pressures that affect the top of the line income statement. In fact more than 50% of all hospitals report negative profit margins (Sinreich, Jabali, 2007, p. 301). This is why it is essential for hospitals to start looking forward toward more sophisticated business strategies in order to succeed. You read "L ondon Bridge Hospital Operational Methods and Strategies" in category "Essay examples" The London Bridge Hospital uses differentiated marketing strategies and programs, long term planning on service lines and broader use of advertising in order to be able to succeed in its business operations. It does this in tandem with adopting broader logistical and operational techniques into the business affairs of the hospital. The London Bridge Hospital monitors and maximizes labor productivity for all the medical support and allied health professionals as a way of maintaining salary expenses. The other strategies that other hospitals have adopted but are not currently in use by the London Bridge Hospital include: Incorporation of methods of scheduling optimization and queuing theory to eliminate time wastage and cycle time out of hospitals. Incorporation of techniques of logistical and supply chain in reducing operational expenses. Elimination of excess safety stocks. General improvement on the management of the working capital. Use of technology in the automation and streamlining of all the hospital operations to reduce operational costs and maximize efficiency. The hospitals and other healthcare organizations cannot depend on the extrinsic factors like shifts in managed care market structures and health policy as tools for changing their margin potentials. Although the macro level issues are important, the organizational and micro economic issues are more important as they have a strong and direct impact on a particular organization. In fact all the microeconomic issues are a function of operational management. As such, operational management is a set of intrinsic decisions and processes that assist in addressing productivity, costs, process and technology (Ford et al 2004, p.26). Healthcare is a primary service sector because the industry provides intangible goods to the customers. The goods here cannot be seen or touched. The services provided by the London Bridge Hospital and other hospitals in the industry are somewhat unique, differentiated, knowledge based and have high levels of customer interaction (Teoh, Pan, Ramchand, 2012, p.588). There are also physical goods that accompany the service in the hospitals which the supply chain procures and replenishes. The hospitals also store medical supplies and pharmaceuticals. Therefore, in this regard hospitals have a mix of both tangible and intangible characteristics. It is these attributes that make operations management in hospitals a little different from those of other industries that strictly produce physical goods. It is in this regard that Harper (2002, p 171) defines healthcare operations management as the quantitative management of processes and supporting business systems that transform resources (inputs) into healthcare services (outputs). Inputs in this case refer to the resources and assets like equipment, labor, technology, cash, personnel and space. The outputs include actual production and delivery of healthcare services. Quantitative management uses extensive quality improvement techniques, optimization and analytical tools to drive improved results. Healthcare operations management integrates quantitative or scientific principles in determining the most optimal and efficient methods of supporting patient care delivery. Functions of Healthcare Operations Management Healthcare operational management is a relatively new field in healthcare although it has been in existence in the other industries for many years. Its scope includes all functions related to business processes and management systems that underlie clinical care. It includes physical labor, physical network optimization, workflow, process engineering, supply chain and logistics management, capacity design, staffing and productivity management (Lorence Jameson 2002, p 749). The healthcare operations and logistics management includes all the business functions that provide job opportunities for the people like administrators, operations supervisors and scheduling manager. Operations Management Objectives or Issue to consider Workflow processHow many manual processes exist? Are there ways of reducing steps, cycle time and choke points for the key processes? Can we improve speed and patient satisfaction? Are there too many departments or people performing the same task? Capacity design and planningHow to reduce bottlenecks to improve the experience of patients? In which case to increase the use of technology to improve labor productivity? Staffing levels and productivity managementHow much output to expect from the employees? Have we maximized the use of automation and electronic commerce in increasing productivity? Quality, planning and process improvementDo we know how to compare the key competitors? Do we use advanced tools for tracking projects? Have we identified the quality issues that affect the goals of customer satisfaction and efficacy? Physical layoutAre the hospital facilities designed with the consideration of traffic flow, operational efficiency and consideration of speed? Physical network optimizationHow to strategically utilize vendors and their facilities Where to strategically position the different facilities like pharmacy satellites, supplies and warehouses in order to minimize costs and resources. Supply chain and logistics managementHow much inventory needed at a particular time Whether or not to use perpetual inventory in ensuring stringent internal controls and accurate financial reporting Have we built collaborative planning and forecasting processes to standardize items and reduce total costs? The goals of operational management The operational management team in the hospital is tasked with different goals and functions in the hospital that include reduction of variability, costs, improve logistics, business processes, productivity, flow of logistics, and quality of customer service. These are explained in more details in the following sections Reduce costs The primary role of operational management is to take out the costs of the healthcare system. It finds waste, improves utilization, stabilizes and reduces the overall costs of service delivery. A hospital that has an appropriate management and tracking system with the ability to isolate material, personnel and other resources utilized for delivery of care is more likely to reduce the costs of operation because it has a good understanding of the underlying cost structure (Teoh, Pan, Ramchand, 2012, p. 591). Once the costs have been identified and all unnecessary wastes eliminated then an organization can operate efficiently. Reduce variability and improve the flow of logistics The operations management team should continually look for more efficient and optimal ways of moving both physical and information resources. This should go together with reducing variability. Chahal (2010, p355) defines variability as the inconsistency or dispersion of inputs and outputs. Variability disrupts processes because it leads to uncertainty, too few or many resources and inconsistent results. For instance, if there are 30 patients seeking treatment in a certain hospital within a specific period, and then in the following period the number doubles or triples it creates problems for the employees in terms of controlling waiting times and general management of patient flows. An improvement in flows means higher yields or throughput with the same level of resource input. Shapiro Shapiro (2003, p246) define throughput as the velocity or rate at which goods are delivered or services performed. In the hospital situation, if a hospital attends to ten patients per hour and can inc rease the number to 15 per hour then this represents a 50% improvement in throughput and logistical flow (Miller, Sumner, Deane, 2009, p. 156). In the same manner, if the number of patients in the hospital doubles and the hospital manages to maintain the same historical inventory levels of pharmaceutical supplies then this is a significant improvement in material flow owing to the higher level of capacity utilization. Resource consumption and staffing should be directly tied to workload and patient volumes (Cowen, 2008, p.410). If the number of patients increases the quantity of the resources should equally increase. Good management of this variability allows a change in staffing mix and scheduling to accommodate the changes without staffing at the low points, valleys or peaks. Improve Productivity Improving productivity means looking for higher levels of output from all employees and other assets. This ensures that the hospital is operating optimally with high levels of efficiency by not only eliminating bottlenecks but also making efficient use of the available resources within the organization (Leury, Jean-Louis, Sicotte, 2003, p58). Improve the quality of customer care Improving quality means reducing medical errors and improving the safety of the patients. Additionally, constant improvement and maintenance of high quality service levels in terms of both patient care and other business services like admissions and cafeteria is also important. In the healthcare industry just like other industries, higher quality services leads to the ability to secure higher prices and this has the effect of driving an increase in operating margins and market shares (McCue McCluer, 2008, p 36). Ensuring an improvement in the patient satisfaction levels and reducing waiting and response times simultaneously ensures that the patients get higher quality services. Continuously improve Business Processes In the highly structured organizations like hospitals, business processes often tend to be unique in all departments as they are not integrated or highly cross functional. For example the operating room of a hospital may handle the procurement of a certain good in a certain way while the gynecology department of the same hospital handles it in a totally different way. Miller, Sumner, Deane (2009, p. 110) assert that in large hospitals most departments operate as independent businesses which lead to multiple problems of efficiency. This is where operations management comes in as it ensures that efficiency and effectiveness are greatly improved in the organization. Recommended Changes From the analysis it is clear that the London Bridge Hospital is performing fairly well in terms of operational management although there are areas that the hospital management needs to work on in order to improve the general performance of the organization. First off the hospital should incorporate methods of scheduling optimization and queuing theory to eliminate time wastage and cycle time out of hospitals. Efficient scheduling and queuing methods will improve the experience of the customers by eliminating unnecessary time wastage. The hospital should also incorporate techniques of logistical and supply chain as a way of reducing operational expenses.Improved logistics and throughput in the hospital will increase the workflow and overall capacity (Noon et al 2003, p97). The London Bridge Hospital should tie staffing and resource consumption directly with workload and patient volumes. This will ensure that if the number of patients increase, then the number of resources should equ ally increase as a response. Once the hospital manages to efficiently deal with the variability in the number of patients, it will have created a change in the staffing mix and scheduling to accommodate any changes. Staffing at the peaks leads to excessive costs whereas staffing for the valleys leads to periodic long lines because of the limited resources. The success or failure of the hospital depends directly on its readiness to cope well with the valleys and peaks without disrupting the normal flow of operations. This is where technology comes in as it automates most if not all of the manual processes. It also improves transaction processing capabilities and the quality of analysis, reports and organizational decisions. This will alter all the economics of the hospital because mechanization allows for faster production and delivery using relatively less resources. Substituting capital or technology for labor especially in the department of business support services will reduce tr ansactional and processing costs in the long run. As such, the role of technology in enhancing productivity is one which the London Bridge Hospital should take into consideration. Conclusion Although operations management is a relatively new phenomenon in the healthcare industry compared to the other industries, it is important to the industry because hospitals face the same challenges just like the other business organizations. The London Bridge Hospital is already making use of most of the principles of operational management although it still needs to implement some changes in its way of operation as highlighted in the discussion. These changes will ensure that the hospital continues to perform well both in the short and long run. Hospital operational management will help the London Bridge Hospital to deal efficiently with the challenges that it is currently facing. Additionally, this paper has shown that the manner in which the hospital responds to the valleys and peaks is critical to its performance. Hospital operational management has the solution for this as it puts in place mechanisms that ensure that the organization makes optimal and efficient use of its resour ces to achieve the best results without any shortages or wastages in terms of resource allocation and utilization.

Some common transitional words and phrases used for the process essay: Firstlastlyfor example Secondfinallyconsequently Nextalso Thenin addition ? Divide your three central paragraphs into organized steps.It is fine if you have more than three steps to your process; your job is to divide all steps into three clearly written and well organized paragraphs. You must plan it ahead of time. The exact time will depend on a lot of inconsistencies that take experience to manage. Find a source or talk to your butcher. The breed of the pig doesn’t really matter, but find out the cost, and make sure you know how many guests are coming to your party. If you have ten to fifteen guests, then you will need at least a thirty pound pig, and when you are ordering a larger roasting pig, you will need to figure two pounds per person. According to my source, typically, a dressed pig that weighs less than a hundred pounds will cost two dollar and fifty cents per pound, and a live pig costs one dollar and fifty five cents per pound. The dressed pig costs more than the live pig, and for a good reason. If you are the type of person who can handle the job, and have an â€Å"iron gut†, you are more than welcome to choose the live pig. But, if you are like me, and don’t want to go through the disgusting process of slaughtering, dressing, and removing the organs and intestines, then I strongly suggest buying a pig that is already clean. It will save you time and energy. My plan is to invite thirty to thirty five people for my party, and to make sure that I will have enough, I need at least a seventy pound pig, which will cost me one hundred seventy five dollars. It might not sound very expensive to you, but in the Philippines, it is lavish! You can buy at least two whole live pigs for that same amount of money. The next step is to prepare the pig pit and the rotisserie. When making your own pig pit, make sure the ground is level. Clear the area by removing the grass, and then prepare an all dirt or sand base at least two to four inches thick. Keep the pit at least twenty feet from the house, and make sure to keep a fire extinguisher on hand in case there is a grease fire. It is better to be safe than sorry. I’m assuming everyone knows how to make a fire. All you need is a lighter, a newspaper, and a lot of charcoal or wood. When buying a rotisserie, make sure that it is strong and sturdy, and it is weight tested for more than what your pig weighs. This is very important. You will use it to lift the whole pig into position over the fire. To get the perfect, crunchy, and tasty lechon, you need to brine the pig for three days and marinate the pig for two hours to give it extra flavor, and to tenderize the meat at the same time. When brining the pig, use a generous amount of kosher salt for brining the skin, and instead of using water, use coconut water for rinsing the salt. Coconut water has a little sweetness, and that will add extra flavor to the skin. Use a clean fifty-to-seventy-gallon drum, add the brine mixture with five gallons of water, and stir the mixture with a paddle until the ingredients are dissolved. Add the pig, tail down, to the drum; add water until the entire pig is submerged. Then you can add two to four bags of ice to the drum. For a whole pig, you will have to leave the pig in the brine for two days. Remove the bags of ice and replace it after every twelve hours. When marinating the pig, you will need six heads of garlic peeled and minced, two ounces of cracked black pepper, twelve large finely chopped onions, two pieces of fresh ginger root each the size of your hand peeled and crushed, five cups of lemon juice, a handful fine chopped scallions, two cups of vinegar, six cups olive oil, and one liter soy sauce to marinate the entire pig. Mix all the ingredients the day before and stir often. Rub the mixture generously inside and outside of the whole pig. You don’t have to marinate the pig for several hours, two hours before the roasting process will be enough. Do not presume that after marinating and brining the pig, you can start cooking it. We are not quite ready yet! Adding a substantial amount of stuffing ingredients such as salt and pepper, two bunches of thyme and rosemary, a fistful of scallions, three heads of minced garlic, five large chopped onions, three sliced lemons, a handful of lemon grass, and adding twenty plantain or potatoes will provide an aromatic and scrumptiously flavored meat. Set aside the stuffing ingredients and ask for help to do the next step. Remember, the whole pig is quite heavy, so you will definitely need extra help do it. Using a bamboo spit (traditionally used in the Philippines), or a solid metal rod, pierce the pig from the mouth to the anus. Once you have completed the process, you can generously add the stuffing ingredients in the cavity, fill the whole body cavity, and slice a thin layer in between the rib cage and the skin section using a sharp knife; then fill the area with a fistful amount of rosemary, thyme and lemongrass. After successfully stuffing the pig, apply the trussing procedure by sewing the abdomen area together using a heavy-duty kitchen twine or wire to keep the stuffing intact, and secure the head and both feet of the pig tightly. Start your fire at the maximum temperature of three hundred fifty degrees Fahrenheit, and gradually adjust it to a low temperature of between one seventy five and two hundred degrees, because we don’t want to overcook the skin. Shuffle the coals around so they all light evenly. Also, keep adding charcoal to maintain the fire and the temperature. Roast the whole pig for a long period of time (five to twenty four hours depending on the weight), constantly turning the rotisserie and brushing the skin with olive oil to develop a nice brown color. Be patient! Most importantly, make sure that the entire body of the pig reaches at least one hundred ninety degrees Fahrenheit. The hindquarters and shoulders will be the last portions to completely cook. Whole pig roasting is extremely hard to get right because the cooking time varies depending on the weight of the pig and temperature outside. It may take longer than what you expected depending on the weather forecast, you might want to look at the weather ahead of time so you will be prepared. The challenge with the whole pig is that there are so many muscles of different thickness with different degrees of fat. The longer the pig is cooked, generally, the better it will turn out. Cook the seventy pound pig about five to ten hours, and watch out for the dripping fat, brush off the fat before it drips down on the coals. It can cause a grease fire that can easily engulf the whole pig. I’m sure you don’t want the whole pig to go to waste and be in the news or on a YouTube video, â€Å"a pig roast gone wrong†, right? It is good to have the fire extinguisher on hand for precaution in case it happens. Keep an eye on the proceeding! After about sixty minutes, sooner if necessary, start another half bag of coals on the side, and add the hot coals as needed before the temperature starts to drop. You want to try to keep the temperature as steady as possible at two hundred degrees. Keep a snack and a bottle of water with you, or a beer, but don’t drink too much, so you won’t feel drowsy; stay awake! However, if you need to leave for a valid reason, make sure that somebody will keep an eye on the pig, and continue the procedure. But you can’t rush the process or predict the time it will be ready to eat. You will know it is done when it is done. It will be ready when it is ready. And to make sure that it is fully cooked, you will need a meat thermometer to test the meat. When it is ready, put a layer of foil in the table (if you don’t have a lechon platter, which is big enough to hold the whole pig) and serve the pig. I prefer to serve the sauce on the side so people can taste the different meats infused with the aromatic flavor of the spices. That way I can offer several kinds of sauce, a citrusy soy â€Å"calamansi† sauce, a traditional Filipino barbeque sauce. To make it, mix soy sauce, hot red pepper, vinegar, and calamansi, a native citrus plant in the Philippines. Sweet and chili sauce, and the famous â€Å"Mang Tomas† sauce, a popular brand name of all-purpose sauce that every Filipino loves, made from water, sugar, breadcrumbs, vinegar, salt, spices, pepper, and liver. In order to find out whether the lechon is perfectly cooked, take one bite of the skin. When you hear the crackling, crispy sound, you know it’s ready! Try to pull out one part of the ribs, and when you notice the moist luscious texture of the meat, and delightful aroma of the spices that is making your mouth water, you know it will be scrumptiously delicious! Grab a bowl of hot, steamed rice and a chilled beer, and enjoy your meal!
