After the public housing policy was broken off, the housing policy for the low-income brackets does not seem to exist any longer. Therefore, the existed public houses are the key of the stable dwelling for the low-income brackets. According to the regulations of urban and residential environment improvement of Seoul, the public housing that was completed in 1989 should be used eighteen years more by 2025, and the public housing that was completed afterwards should be used twenty four years more by 2031 in order to be redeveloped. For the reasons mentioned above, this study aims to evaluate the residential satisfaction through questionnaire survey, and to obtain the direction for the improvement of the residential satisfaction. Among the public housing located in Seoul, seventeen housing complexes that are managed by SH corporation were investigated. The questionnaires were asked the residents who live in the decrepit five cases which were selected on the basic of the completion year. The results of this study are as follows; 'Size of each room', 'size of house', and 'a number of room for a family member' were dissatisfied elements in interior environment. 'A location and a number of bicycle depository', 'parking lot', and 'decrepit level of building' were found that the residents were not satisfied with in exterior environment. Also, 'management expenses', 'the service of management staff and security man', and 'safety management' were the element that the residents were not satisfied with. From fact analysis, the satisfaction factors of the public housing are 'size of residential unit', 'basic supply facilities', 'natural lighting and view', 'safety and security', 'location and exterior', 'parking and traffic', 'community facilities', 'residential cost', 'maintenance'and 'sanitary'.

본 연구는 도서지역에 있는 47개 보건지소에 근무하는 의과 공중보건의사 79명을 대상으로 응급의료 수행 현황 및 지식수준 등을 파악하고자 하였다. 전체 79명의 대상자 중 35명이 설문에 응답하여 44.30%의 응답률을 보였다. 지난 6개월간 도서지역 보건지소에 근무하는 공중보건의사 중 58.68%가 응급의료 질환을 경험하였고, 평균 1.92건의 응급처치를 수행한 것으로 나타났다. 하지만, 실제 응급처치 능력에 대해서는 일부 생명과 직접 연관된 응급처치 능력에 자신이 없음을 호소하였다. 보건지소 근무 의사 중 20.25% 만이 전문의 자격을 갖춘 의사였는데, 응급의료 관련 질환을 처치하는 데 있어 전문의가 일반의와 비교하면 지식수준이 유의하게 높은 것을 확인할 수 있었다. 또한, 지식수준이 높다 하더라도 장비 및 의료지원 등 부족으로 실제 처치 능력으로 이어 지지 못하는 것을 알 수 있었다. 일부 섬의 경우 1명의 공중보건의사만 배치된 일도 있었으나 일반의 1인, 전문의 1인을 배치하는 것이 타당하다는 의견이 많았고, 공중보건의사 배치 이후 부족한 지식 및 기술을 습득하기 위한 교육 및 지원체계가 필요하다는 의견이 다수 있었다. 도서지역은 지리적으로 고립되어 있고, 이용할 수 있는 보건의료기관에 대한 선택권이 적다는 점에서 보건지소의 역할이 무엇보다 중요하다. 특히 응급질환 발생시 보건지소를 이용하는 주민이 많다는 측면에서도 보건지소 응급의료 기능을 강화하는 방안을 마련하는 것이 필요하겠다. 응급의료기능을 효율적으로 수행하고 질 높은 서비스 제공을 위하여 적절한 인력, 의료장비를 갖추도록 하고, 응급의료에 대한 매뉴얼 개발 및 현장교육 체계를 정비하여 최신의 지식과 기술을 보급하는 방안을 강구하여야 한다. Objectives: To investigate the experience and competence of physicians providing emergency medical services at public health sub-centers on remote Korean islands. Methods: This study enrolled 79 doctors who work at public health sub-centers on remote Korean islands. Data were collected in December 2009 via self-administered e-mail questionnaires. The response rate was 44.3%. Results: Emergent situations occurred at most (58.68%) of the public health sub-centers that were surveyed in December 2009. An average of 1.92 cases required treatment by public health physicians. Only 20.25% of the physicians were specialists in emergency medicine, while the remainder were general practitioners (GPs) without clinical experience as emergency doctors. We also found that the physicians we surveyed had insufficient knowledge of emergency medical care. At some health centers only one doctor was available, and there was no medical team in holiday, although most of the physicians indicated that the ideal number of doctors per center was two or three. In cases of emergency, patients were often sent to the mainland by ship without receiving first-aid treatment. The public health sub-centers lacked the necessary medical equipment to save lives in emergencies and lacked escort systems for emergency patients. Conclusions: The Korean government should address the importance of providing emergency care in remote areas. Health administrators should provide suitable manpower, medical equipment, guidelines for emergency medicine, and education for public health physicians on remote islands.

Mixed Use Apartments have been recognized as a new type of urban housing in Korea since government's promotional policy in the middle of 1900's. However, the research on the use of the community facility in the super high-rise mixed-use apartment has not been sufficiently performed to understand the present status of them. Therefore, this study aims to find out residential satisfaction and preference based on use of community facilities to suggest the design guide lines for each community facility in the super high-rise mixed-use apartments. Research methods are as follows; 1. Categorizing the type of the super high-rise mixed-use apartment by placing the community facility. 2. Analysing the variety and size of the community facilities through architectural drawings of nineteen cases 3. Surveying the average using hour a week, satisfaction and preference of the community facilities for each site by type. The results of this study are as follows; 1. Through the analysis of drawings, sports facility and quality lobby were found to be arranged in most cases, than any other facilities. 2. Sports facilities were found to have the highest frequency level of average using hours a week and the highest satisfaction level on the size and quality among the community facilities in the super high-rise mixed-use apartments. 3. The lobby was regarded as a very important design factor, and it may be able to integrate and vitalize the community. 4.

Background: Assay of glycosaminoglycans or proteoglycans from skin is complicated due to individual methods where the measurements are highly specialized. The results from these different methods are not able to be compared and there is a large variance. Objective: It seems reasonable that a major glycosaminoglycan in the skin, hyaluronic acid, might be ideal as a representative instead of the whole components of glycosaminoglycan. To develop a simple and reliable assay method, the in vitro cell culture system was selected to reduce time and variety of data. The usefulness of the ELISA method, using hyaluronic acid binding protein (HA-ELISA), was evaluated. Methods: The amount of hyaluronic acid synthesis was measured under a standardized protocol for cultured human skin fibroblasts from the elderly and neonates, as well as the NIH 3T3 mouse fibroblast cell line. To see whether this screening method (HA-ELISA) could be time-saving and reliable under in vitro conditions, some well-known stimulants for glycosaminoglycan synthesis such as retinol, retinyl palmitate, polyethoxyretinide retinamide and hydroxyproline were treated. Results: The production of hyaluronic acid was influenced by both culture condition and source of fibroblasts. The level of quantity showed different patterns due to factors such as culture period, serum in the medium and cell proliferation rate. We found that stable levels of hyaluronic acid assay from culture supernatant were obtained by delaying the sampling time after 24 hours of treatment with stimulants. Conclusion: For a reliable quantitative assay, either NIH 3T3 mouse fibroblasts or neonate fibroblasts were suitable. The culture condition and time of harvest should be determined first to estimate the stable kinetics of hyaluronic acid synthesis. This in vitro test protocol can be used as an additional evaluation system towards a potential agent for dermal connective tissue, while further efforts are still mandatory to correlate the confounding factors of in vitro and in vivo.(Korean J Dermatol 2006;44(8):950~958)
