  • 최근에 대기오염이 심각해지면서 입자상 물질(particulate matter)의 농도가 증가하고 있으며, 이로 인해 대기의 시정뿐만 아니라 건강상의 문제를 일으킬 수 있다는 보고가 늘어나고 있다. 또한 미세 입자는 화학적 조성에 의해 인체에 미치는 영향이 증가할 수 있다. 중량농도 및 무기이온의 농도는 대부분 겨울철에 높으며, 특히 음이온 중에서는 SO$_4$$^{2-}$ , NO$_3$$^{-}$이, 양이온 중에서는 NH$_4$$^{+}$ 이온이 중량농도 중 차지하는 비율이 높다. (중략)

  • The modern society longing for the convenience of up-to-date technology, there are attempts of miniaturization and high reliance of power equipments in the effectiveness aspect of urban area's usage of space while requiring more electrical energy than now. Consequently, paper used to the Neral Network for a forcasting conservation system. A neral network is powerful asta modeling tool that is able to capture and represent complex input/output relationships. The true power and advantage of neral networks lies in their ability to learn these relationships directly from the data being modeled. Traditional linear models are simply inadequate when it comes to modeling data that contains non-linear characteristics. Form results of this study, the Neral Network is will play an important role for insulation diagnosis system of real site GIS and power eqipment using $SF_6$ gas.

  • This study intended to interpretate the current value of the cultural landscape resources in Gwansan region, Gwangju-si. The 35 significant cultural landscape resources in Gwangsan region appear education, people in history, living residence, religion & belief, distribution of cultural site, tomb, industry, topographic scenery characteristics. They are classified such as 22 traditional landscape resources, 7 modern landscape resources, 6 natural landscape resources. The significant cultural landscape resources were evaluated by value items of 4 natural landscape, 4 social, and 5 cultural. As a result of value evaluation on the cultural landscape resources in Gwangsan region, the highest value were appeared on the cultural items, while the lowest value were appeared on the social items. And high evaluation were appeared on regional identity, cultural preservation, regional monumentality, visibility, while low evaluation were appeared on unique naturality and connectivity of assets.

  • The tall building and super tall building has been a common building type in China, with multiple functions and complex geometry. Composite construction is broadly used in tall building structures and constitutes the mixed structure together with concrete and steel constructions. The mixture of the constructions is purposely designed for specific area based on the analysis results to achieve the best cost-effectiveness. New types of composite construction are conceived of by engineers for columns and walls. Material distribution is more flexible and innovative in the structural level and member level. However the reliability of computer model analysis should be verified carefully. Further researches in the design and build of composite construction are necessary to ensure the success of its application. Composite or Mixture Index is suggested to be used as a performance benchmark.

  • As we have come to realize the problems caused by the modern civilization as well as the importance of the preservation of nature. Ecological building and urban design come to attract more attention. Therefore, the object of this study is providing the design factors and improving the design methods for the developments of ecological housing complex, harmonious with environment. Followings are the results of this study: 1. We need to turn to new trend-Ecological architecture which enables the co-exitence of nature and human being to come over the presence and face new decades. 2. Ecological architecture is based on energy-saving system and give people a healty and comfortable atmosphere. 3. In the city area, the house development should be undertaken to minimize the environmental problem through extremely high ehhiciency and technonogy. 4. We need a new development to preserve natural environment in the suburvan and small or medium city. 5. We have to develope the approach method, which is to maintain the frame of present ecological environment, to be in sympathy with geomorphology, to use the natural material in the rural community.

  • In 1990’ idyllic housing complex is spreading surrounding metropolitan areas of Korea as a result of needs for quality change of housing environment, which was caused by the increase of income, the spread of cars and the change of working environment. On the contrary to the idea of idyllic housing, however, while it is just surrounded by natural environment, it has some critical problems such as the lack of public facilities and its development which often damages the nature. The row houses which this study deals with are popular with working class especially in Europe as an idyllic urban housing. It is noticeable that they have separate private gardens which satisfy the residents'basic needs and save lot areas and building costs more than detached houses. This study intends to suggest row houses as an appropriate housing type for environmentally friendly housing in Korea through the analysis of cases of row houses.
