종래에 헬스케어 영역에서 주로 사용해왔던 기계학습 기법을 U-health 서비스 분석단계에 적용하기에는 여러 가지 문제점들이 있다. 첫째, 아직 U-health 분야의 연구가 초기단계에 불과하여 기존의 기법들을 U-health 환경에 적용한 사례가 매우 부족하다. 둘째, 기계학습 기법은 학습시간이 많이 소요되기 때문에 실시간으로 질환을 관리해야만 하는 U-health 서비스 환경에는 적용하기 어렵다. 셋째, 그동안 다양한 기계 학습 기법들이 제시되었으나 질환 연관변수에 가중치를 부여할 수 있는 방법이 없어, 개인 맞춤형 질병예측 시스템으로 구축할 수 없는 한계를 가진다. 본 논문에서는 이러한 문제점들을 개선하고, U-health 서비스 시스템의 바이오 데이터 분석 과정을 프로세스로 해석하기 위하여, 개인 맞춤형 질병예측 기법인 PCADP를 제안하였다. 또한 이러한 PCADP를 바탕으로 U-health 데이터 및 서비스 명세의 의미 있는 표현을 위하여 U-health 온톨로지 프레임워크를 시멘틱스형으로 모델링하였다. 또한 PCADP 예측 기법은 U-health 환경에서 판별 기법이 갖추어야 할 조건인 유연성과 실시간성이 기존의 방식에 비하여 향상되었고, 판별과정의 모니터링 및 시스템의 지속적인 개선측면에서도 효율적으로 작용함을 확인하였다.

This paper tested by using Micro TSP, an empirical econometric analysis to approve officially a hypothesis of price elasticity of the demand for medical care services in Korean national medical insurance and the economic effect of health care delivery system with time-series datas of Medical Insurance Statistical Yearbook$(1981\sim1993)$. The results suggest that the Korean medical insurance system shows moral hazard due to the change of coinsurance and the economic effect according to intervention of the health care delivery system, but it is different by insurers regardless of the same structure of the medical insurance scheme.

Objectives: The study aimed at reviewing the organizational values, structures, and activities of the health promotion foundation model as a recently recommended by the World Health Organization, and exploring adequate suggestions to administer the funds in Korea. Methods: The study materials were collected from web-sites and visiting, the ThaiHealth, VicHealth, Healthway, and Health Promotion Switzerland were reviewed as the representative cases of health promotion foundation model. Results: According to the review, the health promotion foundation established based on relevant legal acts had the comprehensive and professional organizational structure with boards and committees as governing and supporting bodies. The foundations had clearly defined vision, mission, and purpose, and pursuit health promotion purpose, independent and professional decision making process, strategies and priorities to initiate broad health promotion activities, balanced funds distribution to various areas and sectors, and networking and collaborating with partners. Conclusions: Health promotion foundation is a recommendable model to lead more effective and efficient health promotion activities and to collaborate with other sectors or other countries. Expanded usages of health promotion fund into the diverse health promotion settings such as communities, work places and schools and health activities including sponsorships as well as health promotion programs need to be considered.

The objectives of this study were to evaluate the current state of governance structure and management of the health system to achieve the goals of the health system in South Korea, and to propose reform plan. This study drew implications from the governance of United Kingdom, Germany, and Netherlands, based on the principle of health system proposed by World Health Organization. The presidency and the health ministry should make macroscopic decision-making. The government has to decentralize the enforcement by municipality to operate public health and national health insurance (NHI), and to distribute the centralized NHI fund by municipality. The front line health centers and community centers should provide integrated health and social services. The government has to establish diversified regulatory bodies to enhance both the patient-centered care and the efficiency and equity of health care, and to provide mechanisms for ensuring autonomy of providers. The governance of the health system should be composed of the centralization of macro decision-making, the decentralization of implementation by municipality, the integration of health and social services on the front line, and the well-balanced regulation and autonomy on both consumers and suppliers.

The purpose of this study is to examine the status quo of the networking between health promotion and other programs conducted by public health centers(PHCs), and to develop concrete strategies for improving the efficiency of the health promotion programs at PHCs. Data were collected from a questionnaire survey for 246 PHCs nationwide and 96 questionnaire were returned(response rate of 39%). A focus group study was also conducted to compliment the detail of the networking system between health promotion and other programs at PHCs. The results revealed that the current networking between health promotion and other programs conducted by public health centers is not working well. Especially, the communication networking between health promotion and other programs at planning stage is poorer than the stages of implementation, performance, and evaluation. The main reasons of the poor networking have been caused by an inadequate organizational structure, inefficient information system, low level of motivation for networking among the staff of PHCs, and no concrete guidelines for networking. This study also suggested several strategies to facilitate the cooperation between health promotion and other programs.

Gas sensing element, $\alpha-Fe_2O_3$ was synthesized by dehydration, reduction, and oxidation of $\alpha-FeOOH$, which was synthesized with $FeSO_4\cdot 7H_2O$ and NaOH. They were produced as a bulk-type, a thick film-type. Then, their responses and mechanisms of response to the gas of carbon monoxide were studied. The qualities of gas sefising elements are decided by the structure and the relative surface area. In the process of $\alpha-FeOOH$ synthesis, the effects of reaction conditions as the equivalent ratio, on the structure and the relative surface area of gas sensing element were observed. The changes of the structure were measured with XRD, SEM,TG-DTA and BET. The resistance changes of the synthesized gas sensor in the air were measured. The response ratio were also measured for the changes of working temperature and gas concentration. As a result of analysis with XRD, it was confirmed that the the best conditions for the synthesis of $\alpha-FeOOH$ were equivalent ratio 0.65. The thick film-type element of $\gamma-Fe_2O_3$ responded more quickly than the bulk-type did. The structure and the relative surface area of the $\rho-FeOOH$ were confirmed as the important factors deciding gas response charcteristics.

Optimal sensor placement (OSP) is an integral component in the design of an effective structural health monitoring (SHM) system. This paper describes the implementation of a novel collaborative-climb monkey algorithm (CMA), which combines the artificial fish swarm algorithm (AFSA) with the monkey algorithm (MA), as a strategy for the optimal placement of a predefined number of sensors. Different from the original MA, the dual-structure coding method is adopted for the representation of design variables. The collaborative-climb process that can make the full use of the monkeys' experiences to guide the movement is proposed and incorporated in the CMA to speed up the search efficiency of the algorithm. The effectiveness of the proposed algorithm is demonstrated by a numerical example with a high-rise structure. The results show that the proposed CMA algorithm can provide a robust design for sensor networks, which exhibits superior convergence characteristics when compared to the original MA using the dual-structure coding method.

Heritage timber structures represent the history and culture of a nation. These structures have been inherited from previous generations; however, they inevitably exhibit deterioration over time, potentially leading to structural deficiencies. Structural Health Monitoring (SHM) offers the potential to assess operational anomalies, deterioration, and damage through processing and analysis of data collected from transducers and sensors mounted on the structure. This paper reports on the design and implementation of a long-term SHM system on the Feiyun Wooden Pavilion in China, a three-story timber building built more than 500 years ago. The principles and features of the design and implementation of SHM systems for heritage timber buildings are systematically discussed. In total, 104 sensors of 6 different types are deployed on the structure to monitor the environmental effects and structural responses, including air temperature and humidity, wind speed and direction, structural temperatures, strain, inclination, and acceleration. In addition, integrated data acquisition and transmission subsystem using a newly developed software platform are implemented. Selected preliminary statistical and correlation analysis using one year of monitoring data are presented to demonstrate the condition assessment capability of the system based on the monitoring data.
