The creation and implementation of vaccinations is one of healthcare’s greatest achievements. Vaccinations have saved countless lives and prevented the development of debilitating and life-threatening diseases such as polio, rubella, mumps, pertussis, and measles.Despite the success and benefits vaccinations bring to public health, there has been a growing anti-vaccination trend with claims that vaccinations are dangerous and/or unnecessary. Research the claims and concerns anti-vaccination groups have and determine if there is any scientific validity to this information. Also, research current scientific literature on vaccinations and their overall benefits/risks to public health. Remember to use valid and credible references.As an individual entering into a healthcare profession, you will need to be able to interact with patients about this issue. In your post, address the following questions:How would you address a patient’s concerns, fears, and/or worries about vaccinations? What scientific research would you utilize in your conversations about the benefits and need for vaccinations?

problem 1 2.1  Suggest the most appropriate generic software process model that might be used as a basis for managing the development of the following systems.  Explain your answer according to the type of system being developed: - A system to controlantilock braking in a car. - A virtual reality system to support software maintenance - A university accounting system that replaces an existing system - An interactive travel planning system that helps users plan journeys with the lowest environmental impact problem 2 1.  Select one (or more) of the following agile development components of the XP approach: a.  User stories b.  Refactoring c.  Test-first/Test driven development d.  Pair programming 2.  Describe the component in detail and provide background on its use. 3.  Compare and contrast the pros and cons of the component. 4.  Select one of the four case studies from the text (insulin pump, patient information system, wilderness weather station, digital learning environment for schools). Describe a scenario relative to your selected case study that illustrates the XP component you selected. 5.  Your analysis should be at least 350 but not more than 600 words. problem 3 3.2  Explain how the principles underlying agile methods lead to the accelerated development and deployment of software. 3.3 Extreme programming expresses user requirements as stores, with each story written on a card.  Discuss the advantages and disadvantages of this approach to requirements description. 3.4 Explain why test-first development helps the programmer develop a better understanding of the system requirements.  What are the potential difficulties with test-first development? problem 4 3.7 To reduce costs and the environmental impact of commuting, your company decides to close a number of offices and to provide support for staff to work from home.  However, the senior management who introduce the policy are unaware that software is developed using Scrum.  Explain how you could use technology to support Scrum in a distributed environment to make this possible.  What problems are you likely to encounter using this approach? 3.8 Why is it necessary to introduce some methods and documentation from plan-based approaches when scaling agile methods to larger projects that are developed by distributed development teams? problem 5 Using the patient information system case study: 1.  Create a comprehensive and detailed activity diagram with ten or more elements or nodes. 2.  Identify a set of use cases that illustrate the interactions between a doctor and the Mentcare system. Identify use cases with at least 4 other user groups, such as receptionists, medical records staff, the Human Resources Department, Legal Department, Pharmacy, Safety, Finance Department, potentially the patient population, etc.  Create a comprehensive and detailed use case diagram containing at least five such actors. 3.  Compare and contrast the two different diagramming approaches and how the goals of each vary. This short essay should be between 100 and 150 words. UML diagrams going forward should be developed using a UML diagramming tool such as Gliffy, Creately, etc. Please print the file to a .pdf format prior to turning it in. You may also use drawing tools in MS Word, PowerPoint, or Visio. However, if Visio is used, please print the file to a .pdf format before turning it in. problem 6 5.3 - You have been asked to develop a system that will help with planning large-scale events and parties such as weddings, graduation celebrations, and birthday parties.  Using an activity diagram, model the process context for such a system that shows the activities involved in planning a party (booking a venue, organizing invitations, etc) and system elements that might be used at each stage.
