Web Services – för enklare användning av karttjänster

Detta arbete har bedrivits i syfte att kartlägga funktionalitet, teknik och användningsområde gällande Web Services. Innehållet utgör således en teoretisk utvärdering av Web Services, samt tester av grundläggande programmeringslösningar. De frågor arbetet ämnar besvara är hur en Web Services på lämpligt sätt kan baseras på en befintlig tjänst, samt på vilket sätt denna Web Services kan göra aktuell tjänst lättare att använda. Dessutom belyses eventuella problem som kan uppstå i samband med denna Web Services-anpassning. I syfte att presentera ett lösningsförslag på ovan nämnda frågor granskades, via en litteraturstudie, ett antal informatikrelaterade begrepp liksom faktorer förknippade med kommersiell verksamhet på Internet. Erhållen teoretisk fakta analyserades via empiriskt arbete. Resultaten av analysen indikerar att en Web Services baserad på karttjänsten MapService kan innebära vissa fördelar för det aktuella företaget såväl som för deras kunder. Att bredda tjänsteutbudet med en marknadsdominerande standard innebär vissa fördelar för ett företag, inte minst i form av ett potentiellt större kundunderlag. Kundens vinster utgörs främst av för ändamålet utformade toolkits. Dessa hjälpmedel och verktyg underlättar implementationen av aktuell tjänst. Den ansats som här valts, att designa Web Servicen som en parser (tolk/konverterare) vars huvudsakliga syfte är att förmedla kommunikation mellan användare och befintlig tjänst, har vissa fördelar. Främst det faktum att redan befintlig funktionalitet kan utnyttjas. All kommunikation mellan användare och server hanteras av Web Servicen, som enligt denna princip utgör ett nytt gränssnitt med vilket tjänsten MapService kan användas. Till följd av det omfattande teoretiska utredningsarbetet har detta arbete inte genererat några prototyper, annat än på ett teoretiskt plan. Det problem som återstår är att utreda exakt hur ovan nämnda parser skall vara utformad, för att sedan implementera all funktionalitet som en helhet.

Building a Learning Architecture : e-Learning and e-Services

With the rapid advancement of the webtechnology, more and more educationalresources, including software applications forteaching/learning methods, are available acrossthe web, which enables learners to access thelearning materials and use various ways oflearning at any time and any place. Moreover,various web-based teaching/learning approacheshave been developed during the last decade toenhance the capability of both educators andlearners. Particularly, researchers from bothcomputer science and education are workingtogether, collaboratively focusing ondevelopment of pedagogically enablingtechnologies which are believed to improve theinfrastructure of education systems andprocesses, including curriculum developmentmodels, teaching/learning methods, managementof educational resources, systematic organizationof communication and dissemination ofknowledge and skills required by and adapted tousers. Despite of its fast development, however,there are still great gaps between learningintentions, organization of supporting resources,management of educational structures,knowledge points to be learned and interknowledgepoint relationships such as prerequisites,assessment of learning outcomes, andtechnical and pedagogic approaches. Moreconcretely, the issues have been widelyaddressed in literature include a) availability andusefulness of resources, b) smooth integration ofvarious resources and their presentation, c)learners’ requirements and supposed learningoutcomes, d) automation of learning process interms of its schedule and interaction, and e)customization of the resources and agilemanagement of the learning services for deliveryas well as necessary human interferences.Considering these problems and bearing in mindthe advanced web technology of which weshould make full use, in this report we willaddress the following two aspects of systematicarchitecture of learning/teaching systems: 1)learning objects – a semantic description andorganization of learning resources using the webservice models and methods, and 2) learningservices discovery and learning goals match foreducational coordination and learning serviceplanning.

A web application for follow-up of results from a mobile device test battery for parkinson’s disease patients

Background: A test battery consisting of self-assessments and motor tests (tapping and spiral drawing) was developed for a hand computer with touch screen in a telemedicine setting. Objectives: To develop and evaluate a web-based system that delivers decision support information to the treating clinical staff for assessing PD symptoms in their patients based on the test battery data. Methods: The test battery is currently being used in a clinical trial (DAPHNE, EudraCT No. 2005-002654-21) by sixty five patients with advanced Parkinson’s disease (PD) on 9991 test occasions (four tests per day during in all 362 week-long test periods) at nine clinics around Sweden. Test results are sent continuously from the hand unit over a mobile net to a central computer and processed with statistical methods. They are summarized into scores for different dimensions of the symptom state and an ‘overall test score’ reflecting the overall condition of the patient during a test period. The information in the web application is organized and presented graphically in a way that the general overview of the patient performance per test period is emphasized. Focus is on the overall test score, symptom dimensions and daily summaries. In a recent preliminary user evaluation, the web application was demonstrated to the fifteen study nurses who had used the test battery in the clinical trial. At least one patient per clinic was shown. Results: In general, the responses from nurses were positive. They claimed that the test results shown in the system were consistent with their own clinical observations. They could follow complications, changes and trends within their patients. Discussion: In conclusion, the system is able to summarise the various time series of motor test results and self-assessments during test periods and present them in a useful manner. Its main contribution is a novel and reliable way to capture and easily access symptom information from patients’ home environment. The convenient access to current symptom profile as well as symptom history provides a basis for individualized evaluation and adjustment of treatments.

Improving continence services for older people from the service-providers’ perspective : a qualitative interview study

Objective: To examine in depth the views and experiences of continence service leads in England on key service and continence management characteristics in order to identify and to improve our understanding of barriers to a good-quality service and potential facilitators to develop and to improve services for older people with urinary incontinence (UI). Design: Qualitative semistructured interviews using a purposive sample recruited across 16 continence services. Setting: 3 acute and 13 primary care National Health Service Trusts in England. Participants: 16 continence service leads in England actively treating and managing older people with UI. Results: In terms of barriers to a good-quality service, participants highlighted a failure on the part of commissioners, managers and other health professionals in recognising the problem of UI and in acknowledging the importance of continence for older people and prevalent negative attitudes towards continence and older people. Patient assessment and continence promotion regardless of age, rather than pad provision, were identified as important steps for a good-quality service for older people with UI. More rapid and appropriate patient referral pathways, investment in service capacity, for example, more trained staff and strengthened interservice collaborations and a higher profile within medical and nurse training were specified as being important facilitators for delivering an equitable and highquality continence service. There is a need, however, to consider the accounts given by our participants as perhaps serving the interests of their professional group within the context of interprofessional work. Conclusions: Our data point to important barriers and facilitators of a good-quality service for older people with UI, from the perspective of continence service leads. Further research should address the views of other stakeholders, and explore options for the empirical evaluation of the effectiveness of identified service facilitators.
