The importance about the maintenance consideration of the building has a great impact and regarding the life continuation of the building the many interest is becoming intensively. The housing lot of the heart of urban at the capital region has insufficient recently and the construction of the ground complex building in solution for the insufficiency is increasing at the rapid pace. The ground complex building is brings the maximization of land use from inside the site, but maintenance consideration phase is caused by administration cost share and administration bound limit where person is concerned for a many problem point it contains. The objective of the present paper is that the building is maintain an efficiency initially and is improve in order to develop guide line for a maintenance consideration improvement from design phase. According as literature research and question research is enforce, the paper is escape problem point the maintenance consideration and is bring up guide line for the architectural plan field and the maintenance consideration improvement of the building. Result of the study is expected a help in maintenance consideration improvement during life cycle of the building

지능형 건물 인증제도의 적용대상은 건축물의 용도에 따라 크게 주거용 건물과 비주거용 건물로 나눌수 있으며 건축시점에 따라 신축건물과 기존 건물로 나누어 고려해 볼 수 있다. 또한 시행주체에 따라 공공발주 건물과 민간발주 건물로 나눌 수 있으며 건물의 규모 및 집합형태에 따라 적용대상을 단일건물, 복합건물 등으로 구분할 수 있다.

In spite of a construction of many set building, the government's set building policies being almost indifferent to the maintenance management of them. Currently the personnel is not enough for maintenance management in set building. Therefore many set building does not become accomplished appropriately. On this paper, the set building policies and a questionnaire are analyzed. The result of questionnaire provides fundamental data of proper staff calculation.

Recently, remodeling has been a major field of the building construction that comes up for the alternatives of the reconstruction and the economical construction method. In the almost cases, the engineering capacity for the repair/rehabilitation of the remodeling should satisfy also the owner's various needs (eg, the minimum construction time, etc.) and the safety of the building. Also, the engineering and construction technique for remodeling should be applied to the contrary point of view of the general construction method. But, the many problem actually has arose from the wrongly applied construction method that is caused with the insufficient researches and development. Therefore, this study would suggest the necessities and the directions of developing the elementary engineering technique and the method that satisfy the owner's various needs for the remodeling and repair/rehabilitation of the multi-owned building as multiplex shop, with the successful construction cases.

If we think about the form of housing architecture, we can find a general or typical type has been through the architectural history. because the formal transformation in housing architecture is very difficult. Recently, there are many housing works in powerful ocean state, netherlands that was different from the typical type in the form of housing architecture. This study focusing on the formal characteristics in such works. Such distinctive works in netherlands is the result from an attempt to fulfill the diverse needs of our contemporary society and in an effort to refuse the typical type of the modern architecture. The main purpose of this study is to reveal the meaning of typological transformation in the contemporary' housing architecture.

최근 수도권에서는 지방공단 등으로 이전한 노후 공장 건축물을 철거한 자리에 '테크노타운', '벤처타운', 'IT타워', '디지털밸리', '테크노밸리' 등의 이름으로 아파트형 공장을 설립하고 있다. 아파트형 공장은 서울을 중심으로 수도권역에서 토지이용을 극대화가기 위한 집합 공장건물로서 중소기업체의 입지 해결 및 쾌적한 작업환경을 제공하고 도시근로자의 풍부한 노동력을 적극적으로 활용하고 있다. 또한 공동 부대시설을 확보하여 공간효율의 극대화와 종업원의 복리후생이 개선되는 등의 중소기업 지원효과를 거두고 있다. 고층화, 집단화, 공동화를 주요 특징으로 하는 아파트형 공장에서 부속시설의 화재보험요율 적용에 관하여 생각해보고자 한다.

Recently, many accidents occur frequently because sprinklers aren't installed or don't work right when there are outbreak of fire in houses and aggregate buildings. Therefore, they can result in damage for humans and loss of property. Sprinklers are the most appropriate which can extinguish buildings' fire in the initial stages. Through lack of legal system, in domestic cases, sprinklers cannot operate their inherent performance. Domestic standard simply classifies installation objects according to types of business and forms of buildings, also divides into uses and floors of buildings. Especially it only regulates that sprinklers must be installed every floors in particular fire buildings that have more than eleven floors. While it doesn't need to install sprinklers below ten floors, so we are threatened the safety. In this study, we derived causes and implications by analyzing concepts of sprinklers facilities, installation standards in domestic and foreign legal system, and recent cases that expanded damages in fire accidents because of weak point of installation and control standards. In domestic cases, as a result, government has to provide an institutional strategy and law that regulate duty to install sprinklers to all aggregate buildings regardless of floors in terms of new buildings. Also, if someone who has existing buildings wanted to install them, government would guarantee subsidy to encourage installation. In addition, government supervises fire-fighting activities when there are fire by compensating standards about regular inspection by a qualified technician, operation and maintenance of sprinklers as well as reinforcement of administrative criteria.

The aim of the study is to examine the applicability of FRBRoo / CIDOC CRM to conceptualize information resources for localities. It attemps to establish the conceptual structure and the relationship of them and seeks ways to apply the model. For this purpose, almost 30 articles specially in localities research were analysed and categories of information resources for localities were identified. After examining conceptual model in cultural information management sectors (library, museum, archive), 6 case of conceptualization were attempted based on FRBRoo / CIDOC CRM. In conclusion, it presented that FRBRoo / CIDOC CRM could be applied to various type of information resources for localities and that it could be possible to represent information resources based on particular space(place, local) through the conceptualization.

In this study, basic data that can be referenced for ventilation modeling was presented by analyzing the characteristics of wind pressure coefficients(Cp) according to wind direction angles under conditions of different building layouts and aspect ratios through CFD (Computational Fluid Dynamics) analysis for flat-type apartment complexes. In the case of a wind direction angle of 0°, Cp distribution in the form of an inverted S-shape was shown on the front of the building located on the windward side. And Cp corresponding to the lowest floor, the uppermost floor, and the two inflection points showed relatively close values regardless of the height of the building. The inflection point of the low-rise part was formed at a height of about 11m, and the height of the high-rise part could be calculated through a trend formula proportional to the height of the building. It was confirmed that the averaged Cp value can be applied in most conditions except for the wind direction angle of 45 degrees.

Aircraft-warning lights are lights that are used to inform pilots in flight about the presence of buildings or dangerous objects. Currently, the light sources of most aircraft-warning lights have been replaced by light-emitting diodes (LEDs). However, the aircraft-warning lights that are installed do not meet the optical performance standards and may cause airplane collisions. Therefore, the use of such light poses a risk to aviation safety. In order to solve this problem, we designed a Fresnel lens with the same luminous intensity distribution ovef $360^{\circ}$ direction; thus, we collimated the light beam from the LED light source with a narrow beam divergence angle in the form of an array of aspheric pieces. After that, we designed and simulated an aircraft-warning-light optical system with a center luminous intensity of 20,000 cd and a vertical divergence angle of $3^{\circ}$ or more by optimizing the lens' tilt and the distance between the LED and the Fresnel lens.
