It can be obtained from hydrocarbon and water, specially production of hydrogen from natural gas is most commercial and economical process among the hydrogen production methods, and has been used widely. However, conventional hydrogen production methods are dependent on fossil fuel such as natural gas and coal, and it may be faced with problems such as exhaustion of fossil fuels, production of greenhouse gas and increase of feedstock price. Thermochemical hydrogen production by nuclear energy has potential to efficiently produce large quantities of hydrogen without producing greenhouse gases. However, nuclear hydrogen must be economical comparing with conventional hydrogen production method. Therefore, hydrogen production cost was analyzed and estimated for nuclear hydrogen as well as conventional hydrogen production such as natural gas reforming and coal gasification in various range.

탄화수소 연료(LNG, LPG)를 개질하여 수소를 제조하는 연료 처리 공정 중, 탈황 기술은 촉매의 활성저하 및 전극의 피독을 방지하기 위한 필수 기술이다. 본 연구에서는 도시가스 및 액화석유 가스용 부취제로 사용되는 유기 황화합물(,DMS, THT, TBM)을 제거하기 위한 탈황제로서 Cu/ZnO계 흡착제를 개발하였다. 공침법을 이용하여 흡착제를 제조하여 각 부취제별로 상온 및 고온에서의 흡착탈황 성능을 조사하였으며 또한, 이의 특성분석을 행하였다. Cu/ZnO/Al₂O₃ 탈황제는 메탄으로부터 고온에서 TH, DMS, TBM+THT 등의 황화합물들을 매우 효과적으로 제거할 수 있었다. 특히, TBM+THT의 혼합가스에서 TBM에 대해 선택적인 흡착을 보였다. THT 흡착에서 흡착온도가 300?C 이상에서는, 흡착과정 동안 황의 상호작용으로 인해 금속황화물이 생성되었다.

The purpose of this study is to analyze the housing form according to the combination of unit types to suggest the probability of variable life. The combination of access method, core locations and unit types may generate a range of dwelling alternative. These elements must be considered in the planning and production of dwellings to satisfy user's needs and preference. They indicated alternatives to involve more dwellers in the creation of their own living environments to improve the quality of dwelling. In the past, there have tended to look upon the problems of the negative aspect of the unified house building. As describing the newly aroused forms of urban housing complex through the combination of access and unit types in recent decades in Seoul and it's suburb, it defines forces which have determined present and future housing's form. The results of this study are as follows; as economical situation and household income changed, the development of the individualized housing form in the planning and production should be needed. The range and type of dwelling unit allow for different flavor of user. It can also encourage dwelling alternatives, choice and diversity of demander. The demander's needs and preference aroused new dwelling forms make the creating of individual lifestyles available. In the future, housing must be produced to meet the demand of people.

The study is concerned in description and analysis of the residential environment of Haeundae New town in Pusan. It aims how the neighborhood is formed through commercial facilities and public facilities, in terms of their location, sort and size, distribution of space, approachment. Those elements have influence on the formation of community area and residential environment. Finally, this study identifies the concepts and elements in the community area in the new-built residential environment for improving the quality of the life.

The purpose of this study was to analyze the changes of housing types according to the change in historical and urban situation and to improve the housing types for the dwelling quality and residential environment in Busan. The results of this study were as follows; the housing types changed rapidly from single detached house type to collective dwelling forms year after year. There were not enough variable housing types to improve the quality of lifestyle and to generated a range of dwelling alternatives. The unique historical and urban situation in Busan might not influenced to the change of the housing types. The housing types must be considered in the planning and production of dwelling units to give user the dwelling quality and to generate a range of dwelling alternative. The type of dwelling unit will be considered and developed under the geological and urban situation. It makes not only the dwelling alternatives but also urban quality vailable.
