이순영,김선우,Lee, Soon-Young,Kim, Seon-Woo 대한예방의학회 1998 Journal of Preventive Medicine and Public Health Vol.31 No.1
The purpose of this study was to investigate the relation between health behavior patterns and demographic, socio-economic characteristics, health status, health information in Korea. The quantification method through canonical correlation analysis was conducted to the data from Korea National Health Survey in 1995, which consisted of 5,805 persons. The health lifestyle patterns were quantified as good diet lifestyle, passive lifestyle to the negative direction and drinker lifestyle, smoker lifestyle, hedonic lifestyle and fitness lifestyle to the positive direction. The covariate were related to health lifestyle patterns in the order of sex, age, marital status, occupation, health information, economic status, level of physical labour and health status. Characteristics of male, age below 50, married, blue colored worker, no health information, low in economic status, heavy level of physical labour, and poor in health status were positively related to drinker lifestyle, smoker lifestyle, hedonic lifestyle, fitness lifestyle sequentially.
퍼지규칙에 의한 직.간접 혼합 신경망 적응제어시스템의 설계
이순영,장순용 한국정보통신학회 2000 한국정보통신학회논문지 Vol.4 No.3
본 논문에서는 직접 적응제어기와 간접 적응제어기를 Lyapunov 안정도 이론에 근거하여 결합하였다. 제어기는 RBF 신경망을 이용하여 구성하였으며 하중파라미터들은 적응칙에 의하여 조정되도록 하였다. 또한 시스템의 성능에 영향을 미치는 결합 가중치는 퍼지 If-THEN 규칙을 이용하여 결정되도록 하였다. 이렇게 함으로써 직접 적응제어기와 간접 적응제어기의 장점을 지니는 직 간접 혼합 신경망 적응제어기를 구성할 수 있었다. 제안한 알고리즘의 효용성을 보이기 위하여 일축 강페 로봇 매니퓰레이터를 대상으로 시뮬레이션한 결과 만족할 만한 성능을 보였다. In this paper, the direct and indirect adaptive controller are combined based on the Lyapunov synthesis approach. The Proposed controller is constructed from RBF Neural Network and weighting parameters are adjusted on-line according to some adaptation law. In this scheme, fuzzy IF-THEN rules are used to decide the combined weighting factor. In the results, proposed controller has the main advantages of both the direct adaptive controller and the indirect adaptive controller. The effectiveness of the proposed control scheme is demonstrated through simulation results of control for one-link rigid robotics manipulator.
경성부립부민병원의 운영과 경성 내 의료접근성 해결의 한계

This article examines how medical administration and social projects combined and were used during the transition of colonial policy in the early 1930s by analyzing the background, operation, profit structure, and user characteristics of the Gyeongseong Bumin public hospital. The Gyeongseong City government continued to devise measures to carry out hygiene and medical projects even in the absence of medical administration authorities and facilities. In the first half of the 1920s, the establishment of a direct medical institution was planned, and in the second half, a path was created to implement free medical care through the social welfare commissioner system. In 1931, the government launched a “social project” in earnest and set up various initiatives; as part of this process, it submitted a plan to establish a municipal medical institution called the “Low-Priced Clinic Installation Plan.” Bumin Hospital did not strictly comply with user regulations. This is because it was advantageous for the hospital to receive many paying patients, as it operated with the income from user fees and the fees spent by paying patients. Most of the paying patients were middle-class Koreans who had difficulty using existing medical institutions. Therefore, the reliance on Koreans was gradually expanded at the hospital. At Bumin Hospital, the management policy was based on the revenue structure of beneficiary burden and the profit structure of outpatient care. This allowed it to minimize the financial drain on the city’s government. However, due to the profit structure centered on outpatients, which increased the turnover rate, medical treatment and a lack of facilities worsened at Bumin Hospital. The facilities were also not actively improved to reduce the financial burden on the government. These structural problems were passed on to relatively low-income Koreans, who could not afford to choose other medical institutions.
