Background: The resource-based relative value scale has been applied to Korean medicine services as part of the National Health Insurance, yet the proper scoring method for physician's work needs to be developed. Objectives: To measure physician's work for Korean medicine services using Analytical Hierarchy Process(AHP) and to compare results abstracted by AHP with those by Magnitude Estimation method. Methods: We developed the AHP questionnaires for Korean Medicine services and administered it to 12 Korean medicine insurance experts. Weighted scores were calculated and were converted into physician's work scores. Results: In AHP measurement, the physician's work scores for acupuncture activities, especially special acupunctures, far increased, while those for diagnosis and basic consultations decreased. Variations in the scores enlarged. Conclusions: As an alternative, AHP method can be considered for measuring the physician's work for Korean medicine services with careful management of scoring variation.

Cloud services are often provisioned to their customers using user-friendly web browsers with flexible and rich plug-in environments. Delay is one of the fundamental performance metrics of these web-based services. Commonly-used network measurement tools usually only measure network delay and it may be difficult to infer the web-delay performance using only network layer measurement approaches. In this paper, we propose to evaluate the application layer delay in a browser-based network measurement platform using engineered scripts. We conducted a delay measurement study using instrumented scripts in the proposed browser-based measurement platform. Our investigation included a comparison study of three browser-scripting delay measurement methods, including Java applet, JSP and Flash ActionScript. We developed a browser-based delay measurement testbed over the Internet so that different delay measurement tools could be evaluated in the same real network environment including typical Internet paths and the Baidu cloud. We also decomposed the components of the end-to-end delay process of the above measurements to reveal the difference and relationship between the network-layer delay and the application-layer delay. Our measurement results characterize the stochastic properties of the application-layer delay over real Internet paths, and how these properties vary from the underlying network layer delay. This browser-scripting measurement approach can be easily deployed on different cloud service platforms to inspect their application-layer delay performance between end clients and the cloud platforms. Our measurement results may provide insights into designing new cloud services with enhanced quality-of-experience perceived by cloud users.

To find what has an effect on eating habits of 5th year elementary school students, areas and food services are researched. This research is classified into general items, nutrition knowledge, and eating habits of the subjects. Nutrition knowledge is different in each area, scoring 7.09 out of 10. Food Service has an effect on eating habits, scoring 4.69 out of 10. This result shows that the role of parents greatly influences eating habits of elementary school students, not areas and food services, and that food service affects improvement of physical condition and prevention of unbalanced diet. Therefore, education at home and school is required.

Purpose: This study aimed to clarify the needs for hospital-based home care nursing medical services in elder care institutions by analyzing the details and frequency of medical services provided by, and the needs for, hospital based home care nursing in select institutions in Korea. Methods: Seventy-seven staffs at elderly care institutions located throughout the country completed self-report questionnaires between February 1 and May 31, 2009. SPSS ver. 14.0 was used for data analysis regarding frequency and percentage, mean and standard deviation. Results: Forty-eight hospital-based home care nursing medical services in eight domains were identified as being needed in elderly care institutions. The most commonly used medical services were providing instruction in oral drug administration, checking drug beneficial/adverse effects, and administering blood glucose test, while the most needed medical services requiring hospital based home care nursing were complex pressure ulcer care, followed by diabetic foot ulcer management and nutrient injection. Conclusion: The present results should provide fundamental data for better healthcare services with hospital based home care nursing at elderly care institutions as part of a 'win-win' strategy through which medical expenses are reduced, insurance costs are kept stable, and safe and high-quality medical services are provided for residents of elder care institutions. Political decisions intended to promote visits by hospital based home care nurses to elder care institutions would be a prudent course.

This study establishes a simple Causal Map in order to understand the structure of Social Network Services(SNS). From this, the paper proposes a simulation with drawing Simulation Model and it examines whether a Dunbar Number is available for the emergence of collective intelligence based on an on-line network. Through my analytical research, it turn out both Closed SNS and Open SNS have their own Dunbar Number. However, it appear that Open SNS can expand infinitely as it has a unique property namely weak tie. This implies that it is significant for a system or policy to be developed in order to overcome the problem of Dunbar Number, whereas restricting the extension of a network by considering the Dunbar Number would have a negative impact on emergence of collective intelligence.

본 연구의 목적은 교육행정정보시스템(NEIS)이 제공하는 학부모서비스의 혜택, 비용, 위험 등이 어느 수준일 때 학부모들이 해당 서비스 혹은 다른 대안을 선택하게 되는지 파악함으로써 대국민서비스인 NEIS 학부모서비스의 활성화 전략을 제시하고자 함에 있다. 대국민서비스 강화의 일환으로 학부모들의 정보욕구를 해소하고자 시작된 NEIS 학부모서비스는 자녀의 교육관련 정보를 제공할 뿐만 아니라 각종 교육정책에 학부모의 적극적인 참여를 유도하고 있다. 하지만 최근 NEIS는 성적처리 오류로 인한 대규모 정정 사태, 접속장애 등으로 언론의 집중조명과 일선교사 및 학부모들로부터 질타를 받고 있다. 더불어 학구적인 측면에 있어서도 NEIS의 수용 활성화를 위한 연구는 교사의 입장에서 기존의 기술수용모형(TAM)을 적용한 연구가 주를 이루고 학부모들이 선호하는 서비스 내용에 대한 연구가 부족한 실정이다. 이에 ANP의 BCR 모델에 따라 NEIS가 제공하는 학부모서비스를 혜택, 비용, 위험 등으로 분류하고 이들 간에 학부모들이 고려하는 우선순위를 확인하였으며, NEIS 외에도 선택 가능한 대안들에 대한 선호도를 비교 연구하였을 뿐만 아니라 민감도 분석결과도 제시하였다. 본 연구를 통해 학부모들이 NEIS 학부모서비스를 잘 활용하지 않고 있으며 또한 자신들이 선호하는 의견을 해당 서비스가 충분히 반영하지 못하고 있음을 알게 되었다. 이에 NEIS 학부모서비스에 대한 학부모의 수용 활성화 방안을 모색하고자 하였다.

Background: Although cervical cancer is preventable and early screening might decrease the associated mortality, challenges faced by the women and health care providers can postpone early detection. This qualitative study aimed to establish patient and provider perceptions about personal and socio-cultural barriers for cervical cancer screening in Mashhad, Iran. Materials and Methods: In the present study, which was conducted in 2012, eighteen participants, who were selected purposefully, participated in individual in-depth, semi-structured interviews, which were recorded, transcribed verbatim, and analyzed using conventional content analysis and Atlas-Ti software. Results: One theme and two categories were derived from data including: cognitive/behavioral factors (lack of a community-based approach to cervical cancer, lack of awareness, wrong attitude and lack of health seeking behaviors) and socio/cultural issues (socio-cultural invasion, mismatch between tradition, modernity and religious, extra marital relationships and cultural taboos). Conclusions: Providing community based approach education programs and employing social policy are needed for preventing of cervical cancer in Iran.

Purpose: Marine transportation companies must improve service quality to secure competitive advantage and continuous relationships with customers. This study explores the value and necessity of service quality in the industry by empirically identifying the factor that would have the largest effect on the improvement of service quality, also examining whether such improvement may actually influence continuous relationships. Research design, data and methodology: Based on an online survey with those in the Korean marine transportation industry, this study conducted statistical analyses using structural equation modeling. Based on relevant previous studies, the current study constructed a total of 55 survey questions. Finally, 281 questionnaires were collected, but 68 were excluded owing to invalid responses. Results: Information service attribute had the largest effect on service quality, whereas communication did not demonstrate a significant influence. In addition, distribution and information services exerted a positive effect on service satisfaction through service quality, and finally influenced relationship continuity. Conclusions: The results shows that marine logistics service quality strategies which were centered on time or local factors, should be considered in terms of the development of innovative services. In particular the improvement of information service systems and strategies in changed business environment.

Multi-agent technologies are essential in realizing the upcoming ubiquitous environment. In the multi-agent environment, each agent has its own set of services and stores these services in the service repository of the multi-agent system. By using this repository, the user can retrieve the most appropriate service. In this paper, we propose an efficient service repository architecture that can improve the existing agent-based service discovery.

This paper propose a personalized defection detection and prevention procedure based on the observation that potential defectors have tendency to take a couple of months or weeks. For this purpose, possible states of customer behavior are determined from past behavior data using SOM (Self-Organizing Map). For the evaluation of the proposed procedure, a case study has been conducted for a Korean online game site. The result demonstestes that the proposed procedure can assist defection prevention effectively and detect potential defectors without deterioration of prediction accuracy comparison to prediction by MLP. Our procedure can be applied to various service industries that can capture fluent customer behavior data such as telecommunications, internet access services, and content services, too.
