최저주거기준은 자본주의 산업화 과정과 급격한 도농인구이동 과정에서 공통적으로 나타난 노동자계급의 주거환경 악화와 공중보건위생 문제에 대처하기 위한 수단으로, 주거복지 정책의 주요 쟁점으로 발전하였다. 본 논문에서는 주요 선진국을 대상으로 최저주거기준이 제도화되는 역사를 살펴보고, 서울시를 대상으로 2011년에 개정된 새로운 최저주거기준을 적용하여 1995년 이후 최저주거기준 미달가구의 시계열적 변화패턴과 지역별 특성을 분석한다. 분석결과 2010년 서울시의 미달가구는 50.1만 가구(136.8만 명, 14.4%)로 전국 평균인 11.8%에 비해 처음으로 높아졌으며, 2005년의 50.9만 가구에 비해 거의 감소하지 않은 것으로 나타났다. 이와 같은 서울 최저주거기준 미달가구 감소추세의 정체는 다른 시 도, 다른 시기에는 한 번도 관찰된 바 없는 현상으로서 개별 가구의 독자적인 능력만으로는 주거환경을 개선 할 수 없는 구조적인 한계 가구 층이 존재한다는 것을 알 수 있다. 아울러 서울시의 기타 거처(1.3%) 및 지하 옥상 거주 비율(9.6%)이 전국에서 가장 높아 서울시의 주거환경이 질적인 측면에서 가장 열악한 지역으로 변하였다는 것을 알 수 있다. 미달가구의 공간적 분포는 동북권과 서남권 방면으로 양분되어 있고, 여성가구주, 중장년층, 이혼가구, 저학력 및 대학 대학원 재학생, 비아파트 거주가구, 15~20년 경과주택 등에서 높은 미달비율을 보이고 있다.

The purpose of this study is to investigate how much people recognise and participate in wastes recycling and to give suggestions for systematic environmental education on the recycling. Subject's recognition degree on recycling mark which had been established by The Ministry of Environment in 1995 was very low and the recycling mark should be educated because it would help people consider the environmental factor when purchase goods which are recyclable or not. They acknowledged simple recycling methods of recyclable goods much but not the complex methods of them. So they need the systematic education on recycling method through which continuous participation of them would be arisen. In the while there is no mention about recycling mark in textbooks which are currently used in Korean elementary schools, middle schools and high schools. Not only the mark but also any kind of environmental information should be updated in environmental textbooks/learning materials to cultivate students environmental literacy to meet current environmental issues dynamically and solve environmental problems in the future successfully.

학교에서 표준화된 원자력 및 방사선 기초교육을 실시하기 위해 학생, 과학교사, 전문가의 입장을 반영한 교육과정을 개발하였다. 초(78.4%), 중(78.6%), 고등학교(93.1%) 모두 높은 빈도로 원자력 및 방사선에 대한 학교교육이 필요하다고 나타냈다. 교과목 제목은 초등학교의 경우 "방사선과 생활", 중, 고등학교의 경우 "원자력과 방사선"이다. 학급별로 한 학기, 주당 1시간(초등학교 40분, 중학교 45분, 고등학교 50분 기준) 교육을 요구하였다. 교재는 얇고, 만화와 사진이 많이 포함된 것을 요구하였다. 교육 시작시기로는 초등학생은 6학년, 중학생은 2학년, 고등학생은 1년 때 배우는 것을 요구하였다. 교육형태는 정규교과가 아니라 창의적 체험학습으로 학교와 과학교사의 필요에 따라서 선택하는 것을 선호하였다. 학급별로 교육시간, 교재형식, 교육형태, 교육의 필요성에 대해서 모두 같은 요구 경향을 나타냈다. 고안된 교육과정을 모의 실시한 결과 전체적인 적합도는 5점 만점에서 초등학생 $3.88{\pm}0.60$점, 중학생 $3.89{\pm}0.60$점, 고등학생 $3.66{\pm}0.63$점으로 모두 70점(100점 만점 기준) 이상의 수준을 나타냈다. 본 연구는 원자력 및 방사선이해를 바탕으로 가치판단의 능력을 함양하기 위한 학교 교육과정을 최초로 고안했다는 것에 큰 의미를 둔다. 그러나 원자력 및 방사선에 대한 학교 교육이 실현되기 위해서는 후속조치로 교육과정에 적합한 교재개발, 관련 법령 개정, 교안제공 등이 이루어져야 한다.

Vietnams urban middle class is strongly value oriented in its shopping behavior. They want fairly good quality and service, but they also factor price into their considerations. In terms of retail patronage, they demand convenience, good service, attractive display, and especially want extensive choice. Brands must be present in multiple types of outlet, or fragile brand loyalties can be broken. Mini supermarkets have become an important part of the retail scene in the past decade, and have successfully introduced the supermarket concept to Vietnam. Many consumers are integrating mini supermarkets into their regular shopping, and are willing to pay the higher prices to gain the benefits of such shopping. However, the mini supermarkets do not adequately meet some of the things they expect from supermarkets. Large supermarkets are just entering the market, and are likely to capture much of the current mini supermarket customer base.

To meet increasing power demand, 500 kV power systems are under consideration in the regions of some Middle Asian countries. As the power system voltage becomes higher, the cost for the power system insulation increases significantly. 500 kV transmission systems will become the basis of a region's power system and they require much higher system reliability. Consequently, by the methods of limiting overvoltages effectively, a reasonable insulation design and coordination must be accomplished. In particular, the Substations must be constructed to be of outdoor type. In order to determine the various factors for the insulation design, the EMTP (Electro-magnetic transient program) is used for the magnification of transient phenomena of the 500 kV systems in the planned network. In this paper, we will explain the calculation results of lightning overvoltages by the EMTP for lightning protection design for the 500 kV substations. To obtain reliable results, the multi-story tower model and EMTP/TACS model are introduced for the simulation of dynamic arc characteristics.

This paper is focused on the desirable improvement schemes of the local network of information and telecommunication network. In this study, we examined whether polices of information and telecommunication of government have been carried out a desirable programme to meet the public interest, found out several problems in the these policies. Such problems as follows : (1) a system of local information & telecommunication is developing by a Model of Top-Down. In the present management system, an interest of the public of local society about the local telecommunication network is a much lower level, (2) there is no general controlling roll of the local information & telecommunication, (3) there is no service controlling system of local telecommuni-cation, and (4) there is no organic coordinating system of inter-departments in the central government level. In order to resolve these problems, this study suggests a few desirable sxhemes for the local telecommunication : (1) an establishment of middle-long range planning for the integrated future network of info-telecommunication, (2) an organizing of telecommunication network being suitable for the local characteristics toward B-ISDN.

This study examines control types of IS outsourcing project management focusing on two sets of questions: What control types are implemented during IS outsourcing projects? How various control types affect the performance of IS outsourcing projects. In order to meet these objectives, four control types are developed using typology-approach: dynamic, contract-oriented, partnership-oriented, and passive. And then four control types are identified based on taxonomy-approach using cluster analysis from 66 projects: dynamic, contract-oriented, passive, and middle. The result shows that the derived taxonomy-types are similar to the typology-types except partnership-oriented type. The result also indicates that dynamic and contract-oriented types are in the highest performance, while passive type is in the least performance.

The characteristics of non-point source pollutant loads in middle-stream of Nakdong River Were studied through analysis of pollutant loads of 8 sub-watersheds divided based on administrative district. The pollutant concentration of each sub-watershed was collected from Nakdong-River Water Research Institute and Daegu Regional Environmental Office, respectively. Pollution items analysed in this study were BOD, SS, T-N and T-P. High degree of non-point pollution was observed from Gumi, Goryeong, Gyeongsan, Daegu and Sungju, and pollution was usually increased during rainy season. This result indicates that a given pollution condition within the watershed can be more sensitive than location factor to the level of water quality. The main sources of non-point pollution were population and livestock, as well as landuse factor, and were found to significantly contribute to the water pollution. Alternative solutions for controlling pollution sources, therefore, should be provided to meet target levels of water quality in this region.

The purpose of this study was to analyze the needs of future users for services at senior congregate housing and to look into the development directions of the service standards for senior congregate housing. A survey was conducted among middle-aged people in their fifties, who lived in Seoul, using the systematic random sampling method. The final sample included 498 respondents. The survey was conducted from November 3, 2003 to November 14, 2003. The results of this study were as follows. Firstly, as the need for housing services were high, it was quite clear that various services at senior congregate housing should be provided. Secondly, a service differentiation strategy should be proposed to meet the characteristics of the users. Thirdly, it was hereby suggested that service standards should be established in the following manner considering the relationship between the needs for services and the income level directly influencing the provision of services: 'Basic services' to be provided regardless of income, 'Optional services' to be selectable among the preferable services per income level, and 'Supportive services' to be provided for low-income people.
