This study attempts to investigate the issues of aging population in the context of Singapore through metaphorical approach and the potential of tapping on the collaborative characteristics of a health service cloud computing system to meet the needs in elderly care, hence allowing active aging. The use of electronic health records (EHR) in various countries, particularly the meaningful use of EHR in USA is examined to understand its current features and usage. By employing conceptual mapping and blending of metaphorical study, the concepts in cloud computing are probed to gain better understanding on the characteristics of the technology. Similarly, with concepts drawn from an eco-system blended with concepts in a health service system, the characteristics of EHR and finally the characteristics of a health service cloud computing system are illustrated. With understanding in aging population, present usage of EHR and potential of cloud computing in Singapore, multi-methods research consisting of intensive interviews and archival document collations are employed. Triangulation amongst the datasets collated using open coding via ATLAS.ti resulted in 6 issues of concern in aging population pertaining to the Singapore context to arise, namely (i) primary care, (ii) familial support, (iii) awareness in health maintenance and transparency in information, (iv) improved efficiency and accuracy in healthcare with seamless transfer of care and (v) intermediate care and (vi) collaboration between stakeholders. Further analysis of the results draws up the possibilities for enhancing meaningful use of health service cloud computing system for active aging, which criteria are: (i) empowerment and ownership, (ii) sustainable homecare and (iii) seamless transfer of care. Finally, a conceptual mapping of health service cloud computing system and the criteria for effective aging give rise to a model framework that is set for active aging. / This study attempts to investigate the issues of aging population in the context of Singapore through metaphorical approach and the potential of tapping on the collaborative characteristics of a health service cloud computing system to meet the needs in elderly care, hence allowing active aging.

由於電子化病歷逐漸取代了傳統的紙本病歷，在流通分享上面比傳統的紙本病歷更加來的方便及快速，另外電子病歷的整合性，也是比傳統的紙本來的有效。近年來雲端運算的發展，使得醫療系統在電子病歷上能夠更快速的發展，但是取而代之的是卻是雲端運算所產生隱私權的問題，在快速發展的雲端運算環境中，目前似乎無法完全確保資料的隱私性。即使現有的研究中可以讓資料擁有者表示自己的隱私偏好，卻因為設計時缺乏語意的考量，造成執行上有語意的落差。 本研究將探討電子病歷存放在雲端環境上，設計一套三層整合平台系統並使用語意化技術本體論整合來自多方的資料，達成在資料庫上使用OWL2作為整合的語言，並在此整合平台進行本體論整合，能夠讓使用者可以從多方的醫療中心快速查詢整合的資料，經由整合平台的改寫，到下層的規範擷取到上層平台進行管理與落實動作，最終在資料庫查詢資料，達成整合分享的目標，並同時能夠兼顧資料擁有者的隱私期待，完成在雲端環境上資料分享、整合、隱私保護的目標。 / The Electronic Health Records (EHRs) have replaced the traditional paper Health Records gradually and they are more rapid and more convenient in data sharing. Furthermore, the EHRs are also better than paper health records when health records need to be integrated on the computer. In recent years, the rapid development of cloud computing can help Health Information System to be more dynamic and provide a better service, but the problem of privacy is a critical issue. Although recent research can let data owner expresses his own personal privacy preference in to policy to protect privacy, it is lacked of semantics and that will result in the gap between the real meaning of personal privacy preference and of policy. In our research, we will using semantic technology to express personal privacy preference in to polices and also design the 3-layer integration platform to achieve semantics data integration so that polices can be enforced without loss of real meaning of personal privacy preference and polices will have interoperability with others when we are using semantic data integration.

雲端運算為近年來新興的熱門話題，強調只要透過網路就可以讓使用者依據實際需求彈性地使用計算資源並按照使用量的多寡計費。許多研究報告認為這種將計算、儲存資源以服務形式提供給使用者的租用模式，將有助於節省資訊投資成本而備受企業主矚目；除了節省成本誘因之外，採用雲端運算服務後可能衍生資訊安全、保密的疑慮，也是大家所關注的焦點，因此使用者如何於採用雲端運算服務的決策過程中取得利弊的平衡點相當重要。 本研究將以企業使用者的觀點，探討影響其使用雲端運算服務的決定因素內涵，範疇侷限於台灣的進出口業者。研究根據過去文獻資料，彙整出五個影響使用者決策因素的構面：知覺效益、安全與信任、創新認同程度、知覺有用性以及知覺易用性，並以問卷調查方式進一步瞭解影響企業使用決策的因素；經由問卷調查的結果發現，上述考量構面足以解釋台灣進出口業者使用雲端服務意願百分之六十的變異，而其中影響業者使用意願程度最高的因素為知覺有用性。 / Cloud computing which emphasizes cloud users can elastically leverage computing resources on demand through the internet has recently become a hot issue. Many studies claimed that this rental model of providing storage resources as a service to users would be good for business to save the cost of investing in information technology which attracts lots of business owners. On the other hand, adoption of cloud computing service may arise several concerns like data security, service reliability and so on. In all, it is really hard to strike a balance during the decision-making process whether should business adopt cloud services. In this research, we explored the determinants of using cloud service form business users’ viewpoints which limited to the import/export industry in Taiwan. Based on past literature, we adopted five dimensions in decision-making: perceived benefits, security and trust, recognition of innovation, perceived usefulness and perceived ease of use. Investigating the findings through questionnaire survey, we found that the above dimensions can explain 60% variation of the causes of adopting cloud services to business users and the most sufficient impact factor is perceived usefulness.

雲端運算是近來全世界最熱門的資訊議題，任何設備只要能夠連上網路，就可以享有各種不同的網路服務，這些服務可能建置在不同的機器設備上，甚至可能在相隔遙遠的雲端裡，因此也稱之為雲端服務，在操作過程中，使用者不需要擔心服務安裝在哪裡，亦不用擔心服務如何達成，可想而知網路服務的背後，隱藏著很複雜的技術與架構。 網路服務的開發方式相當地簡單且快速，為系統帶來更大的便利與彈性，不過在管理的部份，卻變得越來越複雜，例如不易瞭解網路的結構與狀態、潛在的無窮迴圈及冗餘的流程問題，甚至是在資源共享的情況下，因等待或其他因素而導致死結的情況產生。這些問題將使得網路服務組合在執行時期，可能發生無法預期的錯誤。情況嚴重時，系統可能會完全鎖死或停止，對公司將造成重大的財務及商譽上的損失。這些流程的問題，需要在網路服務組合執行前先進行驗證，本研究透過流程轉換成派翠網路的分析，以確保流程設計的正確性與穩定性。 因此，本論文運用網路服務標準，將雲端服務轉換成派翠網路模型，再以派翠網路中的針織法為分析基礎，檢驗模型的狀態，避免死結發生，並提供網路特徵報告書，以降低管理的複雜度，進而提升服務的穩定性。 / Cloud computing is regarded as the most popular recent ICT topic. Any equipment which can be connected to Internet can provide its user have the access to the various services, which may be built on different machines, or even may exist in the distant 'clouds' far away. However, in the operating process, the user has no need to worry where the service locates, needless to say how the service operates, which means that a considerably amount of data and techniques hide behind the Web service. Web service is an artifical piece of art, the user and the manager can concatenate several Web services online into a bigger one according to the conditions they need, which is a considerably simple and fast developing method bringing more convenience and flexibility for the system. Nonetheless, the managerial part also becomes more complex in problems like potential infinite loops and abundant procedures, for instance. What is worse is under the circumstance of resource sharing, the deadlocks happen while pending or other factors occur. These issues will lead to severe errors while the Web service compound operates. If the system completely locks and stops, serious financial damage and loss of commercial reputation will be caused to the company. Hence the design of procedures needs to be validated and transformed as Petri Net analysis before the Web service compound operates in order to assure the accuracy and stability of the procedure design. Therefore, this paper uses Web service standards, turning Web services into Petri Net models with knitting technique as analytical base, to validate the accuracy and stability of the model to avoid deadlock to happen in order to enhance the reliability of the service.
