There have been controversies over whether explosion hazardous area(EHA) should be classified for facilities which use lighter-than-air gases such as city gas, hydrogen and ammonia. Two view points are confronting each other: an economic piont of view that these gases are lighter than air and disperse rapidly, hence do not form EHA upon release into the atmosphere, and a safety point of view that they are also inflammable gases, hence can form EHA although the extent is limited compared to heavy gases. But various standards such as KS, IEC, API, NFPA do not exclude light gases when classifying EHA and present examples of EHA for light gas facilities. This study calculates EHA using the hypothetical volume in the IEC code where the hole sizes required for the calculation were selected according to various nominal pipe sizes in such a way to conform to the EHA data in the API code and HSL. Then, 25 leakage scenarios were suggested for 5 different pipe sizes and 5 operating pressures that cover typical operating conditions of light gas facilities. The EHA for the minimum leakage scenario(25 mm pipe, 0.01MPa pressure) was found to correspond to a hypothetical volume larger than 0.1 $m^3$(medium-level ventilation). This confirms the validity of classifying EHA for facilities using lighter-than-air gases. Finally, a computer program called HACPL was developed for easy use by light gas facilities that classifies EHA according to operating pressures and pipe sizes.

This study is to use B.F. certification standards to identify the application and differences of B.F. facilities according to various approaches, and to use the analysis results as basic data for the expansion and renovation of new facilities, the National University (Jeonnam University Library), which underwent remodeling before the implementation of the certification system, and the two newly established private universities (Joseon University Library) that were subject to legal application before the implementation of the certification system. First, Chosun University met more B.F. certification standards than Chonnam National University, and mainly intermediary facilities belonged to the best to the best. Second, Chosun University and Chonnam National University's internal facilities met many B.F. certification standards, and Chonnam National University had many areas to improve and found areas to remodel. Third, information facilities at Chonnam National University and Chosun University only had facilities for the hearing impaired, and there were no information facilities for the visually impaired. Facilities for the visually impaired had to be installed, and compared to Chosun University, Chonnam National University fell short of the B.F. certification standard, so there were many areas that needed to be remodeled.

This study is aimed at classifying different types of parks in Gwang-Ju city and providing efficient Planning and guidelines to satisfy the needs of park users. The first stage of this study was accomplished by site surveys of neighborhood parks in Gwang-Ju where park types, locations, neighboring conditions, park layout, and other physical environments were surveyed for the specific status of parks. With those basic data, urban neighborhood park types were classified into different categories: 1) urban neighborhood parks; 2) riverside neighborhood parks; and 3) natural(mountain side) neighborhood parks. For the second stage of this study, behavior patterns and satisfaction were investigated to provide empirical data on the relationship between the physical environment and human behavior. The main findings of this study can be summarized as follows: 1. The highest level of satisfaction for the users of urban neighborhood parks in Gwang-Ju city is the accessibility of the parks which are small but located in neighborhoods, The users tend to visit the nearby parks regardless of size. 2. The users have relatively high levels of satisfaction for urban neighborhood parks which have a lot of green zones or park facilities. Therefore, the park planner should consider the natural environment in the park area and should reconsider the type of park in the planning process. 3. The different types of urban neighborhood parks in Gwang-Ju city do not affect the level of satisfaction and the motivation of park visits. However, the accessibility of the parks is the most important factors of users' satisfaction regardless of the type of the park. 4. The level of user satisfaction for all of the urban neighborhood parks in Gwang-Ju city indicates that the users have a relatively low level of satisfaction. Especially, 26.2% of the users have a high level of dissatisfaction. The new parks, which have recently been developed, have a higher level of satisfaction than the old parks which have a lack of facilities, insufficient maintenance, and poor management planning in the park. 5. As a result of factor analysis, all city neighborhood parks showed a similar tendency with urban type parks, but showed a tendency that was different from the other park types.

The integrated solid waste management for Seoul Metropolitan city can be established on the basis of the following hierarchy of priorities: 1. Efforts for source reduction should be propelled by both government and citizens to achieve the effects of resource conservation. The adequate production and consumption which are environmentally amenable and sustainable can be induced by the reasonable imposition of deposit money for waste treatment to one-time use products. To accomplish source reduction effectively, the induction of legal and institutional regulation of producer and consumer participation is requisite. 2. For resource recovery, wastes generated should be recycled as far as practicable. Community residents are responsible to separate discharge, the authorities concerned have responsibility of separate collection, and recycling industry should be assissted through tax reduction and financing. Resource separation facilities can be constructed at Kimpo Metropolitan landfill site for wastes not separately collected due to some unavoidable circumstances. 3. Garbage should be composted. Garbage is uneconomical for incineration, because it has high moisture content and low calorie, thus there is no reason for the incineration of garbage even though garbage is classified into combustibles. Composting facilities can be located at sites which are not densely populated and easily accessible to transportation, for example, Kimpo Metropolitan landfill site. Compost produced can be managed by the authorities for the use of fertilizer to a green tract of suburban land and farms. 4. Nonhazardous combustible wastes not recyclable can be utilized for thermal recovery at the incinerators which are completely equipped with pollution control devices. According to the trend of local autonomy and the equity principle of local autonomous entities, incineration facilities of minimal capacity required can be constructed at each districts of Seoul Metropolitan city which have organized local assembly. In case of Yangcheon district, the economically combustible waste quantity is about 260 tons/day which exceeds 150 tons/day, the incineration capacity of existing facility. But, from now on, waste quantity can be reduced substantially by the intensive efforts of citizens for source reduction and recycling and the institutional support of administrative organizations. Especially, it is indispensable for the government to constitute institutional and technological bases that can recycle paper and plastics form 43% of waste generated. A good time for constructing of incineration facilities for municipal solid waste can be postponed to the time that pollution control technologies of domestic enterprises are fully developed to satisfy the standards of air pollution prevention, because the life expectancy of Kimpo Metropolitan landfill site is about 25 years. Within this period, institutional improvements and technological advancements can be attained, while the air qual. ity of Seoul Metropolitan city can be ameliorated to the level to afford incineration facilities. 5. For final disposal, incombustibles and ash are landfilled sanitarily at Kimpo Metropolitan landfill site.

전통적으로 부산 일대에서 전통적인 정치 행정의 중심지는 정주공간인 동래이고, 부산은 동래부 동평현 부산포라는 어촌이었다. 개항 이후 일본과의 연이은 조약으로 일본인의 조선 내에서의 활동범위가 넓어지고 조선에서 일본인의 상업행위가 허용됨에 따라 일본인의 이주가 급증하였다. 일본은 조차나 임대, 매입 또는 매축을 통해 전관거류지와 서쪽 방면 일대, 북항 일대의 부지를 확보하고, 북항 일대에 공공시설과 상공업시설, 철도 항만시설을 구비하여 경부철도와 관부연락선이 바로 연결되도록 하였다. 이처럼 부산이 한일간 교통의 요충지가 되자 부산은 통상 중심의 상업이 발달하고, 부산항은 조선 최대의 무역항으로 자리매김 하였다. 조선이 일본에 병합된 이후 조선총독부는 토지조사사업을 통해 조선의 임야와 거대한 농지를 확보하고, 소작농이 도시 임금노동자로 전락하게 되었다. 회사령을 통해 조선 자본의 성장을 억제하고 일본 자본이 침투하여 일본인 기업이 대거 설립되었다. 1914년에 시가지는 부(府)로, 농촌은 군(郡)으로 지방행정조직이 개편됨에 따라 부산포 일대의 일본인이 개발한 지역은 부산부로, 그 외의 농촌지역은 동래군으로 바뀌었다. 새로 신설되는 공공시설과 상공업시설, 철도 항만시설은 부산부에 집중적으로 들어섬에 따라 변방이었던 이곳이 정치 행정의 중심지로 탈바꿈하였다. 부산이 교통과 교역의 중심지로 성장함에 따라 경상남도의 도청이 진주에서 부산으로 이전하였다. 이로써 부산이 경상남도의 정치와 행정의 중심지로 역할이 확대되었다. 토지조사사업으로 대규모 노동력을 확보하고, 회사령 철폐로 일본이 대자본이 식민지로 진출하였다. 부산진 방면의 매립으로 조선방직 등 대규모 공업시설이 설립되었다. 이런 과정을 통해 부산의 도시 정체성, 즉 로컬리티도 어촌에서 통상 위주의 상업도시로, 나아가 상공업 도시로 변모하게 되었다.

지속가능한 국토개발과 지역균형발전을 위하여 세종시(행정중심복합도시), 기업도시(기업중심), 혁신도시(혁신클러스터) 등 다양한 형태의 신도시가 개발되고 있다. 특히, 세종시가 원안대로 추진되게 됨으로써, 혁신도시의 건설은 보다 탄력을 받게 될 전망이다. 기존 수도권의 신도시와는 달리 혁신도시는 공공기관 및 연구기관을 중심으로 혁신클러스터가 조성되고, 주로 지방의 중소도시 및 농촌지역에 신도시가 형성된 다는 측면에서 도시개발의 차이가 있다. 또한 인구는 대부분 2만 내외의 중소규모 신도시 및 신시가지로 개발되고 있다. 그러므로 혁신도시 내의 교육시설 및 문화시설은 도시규모 및 도시기능상 독립적인 수요를 확보하기에는 한계가 있다. 따라서 다양한 시설을 복합화하여 문화수요를 확대하는 것이 바람직하고 기존 모도시와의 공동이용을 도모하는 것이 도시관리의 차원에서 효율적이라고 할 수 있다. 본 논문에서 는 다른 혁신도시와는 달리 2개 광역지자체의 공동혁신도시이자 혁신도시 중에서 가장 규모가 큰 신도시형으로 조성되는 나주혁신도시를 사례로, 혁신도시 문화교육시설을 활용한 기능과 공간의 융복합적 복합 문화벨트의 조성을 기존의 분산적 문화시설계획방식에 대한 새로운 대안으로 제시하였다.
