Background: Competition among hospitals has intensified, because hospitals and beds are oversupplying and the global medical market has opened in Korea. Method: we developed questionnaires of the patient's satisfaction about 20 items. We surveyed 297 out-patients and 302 in-patients. We analyzed the descriptive statistics and regression by SPSS(Version 17) and Excel. Results: The relations with the patient's loyalty and the specialized hospital service are 1) Recommend to other person: FHR use and the assistant for follow-up treatment were related positively for out-patient and PHR and FHR use were related positively for out-patient. 2) Revisiting: PHR use and the need of an assistant for follow-up patients were related for them and the PayTV were negatively related. Conclusion: FHR, PHR and assistant system for follow-up patient's condition were very useful factors to increase patient's loyalty.

With the paradigm shifts towards consumer-centered health service, it is expected that more health care consumers will keep their health information and manage their own health in the future. Thus, this study was conducted to compare "Understanding", "Utilization" and "Management" of Personal Health Record(PHR) between medical users(healthcare students) and health care providers(medical students). We collected data from 208 health and medical students via using self-reported questionnaires form April to June, 2011. The collected data were analyzed using frequency, t-test, Chi-square on SPSS 19.0 version. There was no significant difference in "Understanding" of PHR between two groups. Looking at the order of the importance of PHR contents, two groups equally emphasized medical records, surgical history, and test results. There was significant difference in both time and effectiveness of PHR(p=0.02). Intergrated type of PHR was preferred by both groups. Recently, PHR reflects needs and demands of users more than ever. However there are many limitations to promote the utilization. In the future, it is necessary to implement targeted strategies for the elderly groups and specific types of disease.

The issue of PHR is maintained on the server will be in the hospital. PHR information stored on the server, such as a patient's illness and treatment is very sensitive information. Therefore, patients should be guaranteed the protection of privacy. In addition, the PHR should be allowed to group access of it's approach. Therefore, in this paper the proposed group signature using hierarchical identity-based encryption schemes into can guarantee the PHR data privacy. The session key generated by group signature, it is use a tiered approach. The generated session keys safe PHR data transmission is possible. The proposed method is average 80% than the PKI encryption and ID-based encryption rather than average 50% the algorithm processing is more efficient

PHR(Personal Health Record)은 다양한 의료기관으로부터 제공되는 개인의 진료정보와 개인 스스로 기록한 건강기록을 통합적이고 포괄적인 관점에서 바라본 개인의 평생건강기록과 그 기록을 관리할 수 있는 도구들을 의미한다. 이러한 PHR 서비스를 제공하기 위해서는 다양한 의료정보시스템에 대한 연동이 필요하다. 그러나 기존의 의료정보시스템은 개발한 회사에 따라서 각기 다른 형태의 데이터베이스 구조를 갖고 있어서 PHR 서비스를 위한 연동이 용이하지 않다. 따라서 본 논문에서는 이에 대한 해결 방안으로서 의료정보 표준의 하나인 CCR 기반으로 한 XML 스키마 형식의 문서를 생성하기 위해 CCR구조 및 스키마를 분석하고 설계 방법을 제안한다.

Objectives The Korean Medicine (KM) PHR platform is a personalized healthcare service which allows individuals to keep and manage their own health records. When parents are reporting for their children from their memories, there is high possibility of recall errors. In these cases, it could be useful for doctors to collect the patient's symptoms through PHR platform. In this study, we aimed to investigate the clinical significance of the PHR by using the KM PHR platform in the pediatric clinic. Methods The PHR platform was used to collect child health information from parents and child care teachers. The collected data were analyzed in comparison with the results of screening by pediatrician. Results A total of 58 children were recruited, 44 of which health information were collected from their parents and their child care teachers. The remaining 14 children's health information were collected from their parents only. As a result the parents tended to perceive their children weaker than the child care teacher. Compared to other organs, there was a only significant difference in the heart weakness score and spleen weakness score in the comparison of the weak and healthy children. Conclusions Although the study was conducted on a small group of subjects, and used PHR platform developed specifically for adults to indirectly input child's symptoms, and analyzed their health information, there was a difference in health records between information providers. Development of PHR platform for children is needed to collect more reliable information.

HL7 released V3 CDA(Clinical Document Architecture) and V2.x message standards for medical information exchange. Currently, these standards are successfully adopted by a number of nations across the globe. However, substantial amount of time is required to develop and implement these standards. Moreover, developers need a lot of time to understand these standards. To solve these issues from 2011, the HL7 standard framework started to discuss Fast Healthcare Interoperability Resources(FHIR) as next generation standard of healthcare information exchange. People's interests toward personal health record and smartphone penetration rate are growing and increasing rapidly. Therefore, our research team believes it is necessary to develop a PHR profiling system which could be accessed by using a smartphone and we developed the system. Through a FHIR Profile editor tool developed in Furore, we found that improvements could be made in generating and changing the profile. In order to build the PHR Profiling system, an Open-API on FHIR is used for exchanging information between electronic medical record system and PHR Profiling system. In the PHR Profiling system, the transactions of information between two systems are provided by RESTful service. In this study, we verify the efficiency of development of the PHR Profiling system through FHIR.

To propagate clinical disease management service, there should be built a ecosystem where service developers, service providers, device suppliers closely cooperate for u-Health platform. However, most u-Health platform is difficult to build an effective ecosystem due to the lack of secure and effective PHR(Personal Health Record) management, the lack of personalized and intelligent service, difficulties of N-screen service. To solve these problems we suggest the CDMP(Chronic Disease Management Platform) architecture. The CDMP is a software platform that provides the core functions to develop the chronic disease management services and performs a hub function for the link and integration rbetween various services and systems. CDMP is SOA based platform that enables a provision of reusability, expansibility and it provides open API where everybody can share information, contents and services easily. CDMP supports the multi platform system foN-screen service and the self management functions via SNS. In this paper, we design and implement the CDMP including PHR service based on hybrid data model for privacy preservation. Experiment results prove the effectiveness of hybrid model-based PHR service.

Personal Health Record(PHR) service can be helpful to patients with diseases requiring strict everyday care and medical treatment, such as diabetes or cancer. In this paper, we propose a PHR system specialized in collecting and analyzing health record data of cancer patients, and present the process of how the system can improve the efficiency of cancer treatment process. Through the smart device application, cancer PHR system obtains daily PHR data which is highly related and critical to cancer therapy. The analysis report is provided to the medical staff with an available format suited for Electronic Medical Record used at medical institution. With the final result of PHR analysis which is easily merged with medical chart, most efficient Chemotherapy treatment can be provided for the patients. Also it is possible for the patients to give the information of side-effect and other pain experience during therapy to their doctors without loss of information. The proposed PHR system has the effect of improving the quality of patient care by allowing the medical staff to acquire the main objective data necessary for drug prescription and medical care benefits.

In this research, magnesium hydroxide as a flame retardant agents and zinc borate as a synergist were mixed with LDPF/EVA blended samples, in order to improve their flame retardancy. We attempted to select the best mixing ratio of the LDPF/EVA blend and the optimum amount of magnesium hydroxide and zinc borate by the comparison and analysis of the flame retardancy, the electrical properties such as the volume resistivity and dielectric loss tangent, and the mechanical properties such as the tensile strength and elongation at break. Particularly, specimen which is the 6phr of zinc borate and 10phr of magnesium hydroxide 70/30phr adding to the LDPF/EVA blended samples has been most excellent in flame retardancy and electrical/mechanical properties.
