One of the most promising applications for u-Healthcare is the ubiquitous home health monitoring system. This paper addresses two significant challenges in the successful application of the ubiquitous home health monitoring system: the uniform integration of measured biosignal data and easy access to monitored biosignal data. Methods: We used the Medical waveform description Format Encoding Rule (MFER) standard to encode biosignal data. A web-based MFER upload ActiveX control was designed and implemented to transfer MFER files to the central repository server in a near real-time basis. All of the integrated biosignal data were then accessed and managed through the central repository server. Results: We developed a u-House server that can serve as a uniform data transferer to integrate measured biosignal data from u-House homes into the remote central repository server. We developed user-friendly web services that allow users to easily search and view monitored biosignal data. Conclusion: The results of this study suggest that the MFER standard can be easily adapted to u-Healthcare systems and that a web-based ubiquitous home health monitoring system has advantages of ubiquitous access and scalability.

This study proposes an efficient feature selection method with a variable threshold. Methods: In the proposed method, the spatial distribution of labeled data, which has non-redundant attribute values in the overlapping regions, was used to evaluate the degree of intra-class separation, and the weighted average of the redundant attribute values were used to select the cut-off value of each feature. Results: The effectiveness of the proposed method was demonstrated by comparing the experimental results for the dyspnea patients' dataset with 11 features selected from 55 features by clinical experts with those obtained using seven other classification methods. Conclusion: The proposed method can work well for clinical data mining and pattern classification applications.

In this study, an evaluation of early phase's knowledge model for hypertension management was conducted to develop a more precise and useful knowledge model. Methods: The knowledge model for hypertension management based on JNC7 was modeled using a knowledge representation tool based on SAGE. Two physicians were involved in evaluating the process of the knowledge model. They reviewed 36 scenarios and made recommendations based on the knowledge model. These recommendations were compared with those derived from the model. Results: Eight algorithms and 223 evidence statements were included in the knowledge model. The concordance rate of the recommendations between the physicians and the model for the goal BP were 61% and 93% by the respective physicians. Six scenarios showed low proficiency and efficiency for drug recommendation. Two refinements of the knowledge model were made based on the results. Conclusion: The evaluation process of the knowledge model in the early phase pro- vides more precise and useful knowledge model in the next.

Methods: A survey was conducted to investigate the private companies that provide healthcare information. For in-depth investigation of the study subjects, they were categorized based on their means of service provision. Open colloquium participation requests were extended to the representative companies, and five open- colloquiums were held. Additional data were obtained through a structured questionnaire investigating the problems and complaints, followed by a discussion on strategies and future plans. Results: Through a review of previous research on internet business model classification, four major model classification systems were chosen and the healthcare information business models were classified. Based on the composite opinions derived from the participating companies, policy guidelines were proposed. Conclusion: It is important to cooperate with experts from each field under governmental supervision and help the general public appreciate the value of healthcare information, thereby achieving the industrialization and development of the health information provision business.

Methods: We developed an automatic detection system to auto-assess the authorship quality indicator of an health-related information webpage for governmental websites in Taiwan. The system was integrated with the Chinese word segmentation system developed by the Academia Sinica in Taiwan and the SVM light , which serve as an SVM (Support Vector Machine) Classifiers and a method of information extraction and identification. The system was coded in Visual Basic 6.0, using SQL 2000. Results: We developed the first Chinese automatic webpage classification and information identifier to evaluate the quality of web information. The sensitivity and specificity of the classifier on the training set of webpages were both as high as 100% and only one health webpage in the test set was misclassified, due to the fact that it contained both health and non-health information content. The sensitivity of our authorship identifier is 75.3% ,with a specificity of 87.9%. Conclusion: The technical feasibility of auto-assessment for the quality of health information on the web is acceptable. Although it is not sufficient to assure the total quality of web contents, it is good enough to be used to support the entire quality assurance program.

The study objectives are to provide detailed guidelines to regulate the access and protection of medical information by analyzing patients' understanding and views regarding the dissemination of medical records. Methods: A self-administered questionnaire was administered to 781 patients who visited five University hospitals located in Seoul, Busan, Gyeonggi, Chungnam and Jeonnam from July to September, 2008 and asked for copies of medical records to be issued. Data were analyzed by using the statistical program SPSS 13.0. Results: More than 70% of respondents wanted to access their medical records after confirming the required documents. The highest distribution in the range of persons able to receive copies of medical records without the individual patient's consent or required documents was 'only personally' in each variable. Copies of medical records were issued mostly within 1 hour, while the appropriate time of issuing the copies was within one day. Half of respondents approved of a subscription system that did not require a doctor consultation. The results regarding changes in the ways to request/issue copies of medical records to improve the convenience for applicants differed significantly according to age. Conclusion: Considering the sensitivity of personal health information, medical records should only be issued with the patient's consent and by confirming the identity of the designated person with required documents. Furthermore, people should be aware of the importance of protecting personal health information, and medical institutes should inform the requirements for bringing the relevant documents. Medical institutes play an important role in protecting personal records, which necessitates generalized guidelines.

Considering this environment and the needs of the individual, this paper has designed and developed a web and mobile storage device-based personal health record (PHR) system that individuals can manage by themselves anywhere, anytime, whether on-line or off-line. Based on the experience of implementing the system, its development method, results, and relevant technical issues are described. System Design and Description: This system is implemented to manage PHR, including vital signs and ingested/consumed calories for a lifetime by connecting a PHR-integrated web server to each hospital's information system, and the PHR programs installed in the individual's PC or USB flash memory drive. To achieve this, an interface module, web server system, and PHR viewer program for individuals are developed. Results: When it is off-line, the PHR program is operated to inquire the data saved in the DB, and the self-measured information can be inputted. When it is on-line, it calls the web service function to inquire the medical information, including hospital visit history, prescription history, diagnosis result, image inspection result and medical treatment result. Conclusion: This system connects home and mobile healthcare to hospitals but minimizes information leakage because the data is not accumulated. By loading a plug & play, PHR viewer to an easy-to-carry mobile storage device, the systems supports a sustainable health management.
