In our country, the application of the design method of face to face dimension in wall-slab apartment has passed 10 years. So MC design method has fixed in the design step to some degree. In Design and Work Execution of House the exclusive area of the apartment was calculated by face to face dimension. And the term of face to face dimension was known broadly to clients, construction company, etc. But design method of face to face dimension is not to simply extend the room size so far as wall depth in design process but to ensure the actual space should be considered with efficient use and assembly of building components. That is to say, Design method of face to face dimension is not to be defined by design step but to be related with construction and maintenance. However in construction process the point of face to face design method was not understood even now. So the purpose of this study was to extract the effect and question of face to face design method in construction process by survey of actual condition of structure and construction quality, and compare this result with existing construction method. The following project of this study is to survey of actual condition of interior components such as gypsum board, windows & doors etc. Therefore this study is to induce architectural long-life through architectural standardization construction and component's exchange, and, by the subject of the study on Apartment to have design guideline and basis for joining part between Gypsumboard and windows.

Currently, it is not popular to use the STEP based product information in the construction drawing files, in spite of the importance and possibility of using various product data in drawing files on the CALS/EC environment. This paper aims to demonstrate a construction drawing information management system based on ISO 10303/STEP. To achieve this aim, the authors have analyzed the current construction drawing information classification hierarchy widely used for domestic and international, and examined the material data connection mechanism within CAD drawing data, and finally investigated the management systems for construction documentations and drawings in a public companies. Therefore, the expected benefit of the proposed system is that STEP drawing information management will be done standardization and the information of STEP construction drawing can be managed, shared and supported design business through materials data connection.

The buildings constructed with steel structure is coated with certified fire resistive material to resist from fire. Coating materials lose their initial performances as time passes, so they need some maintenance. This study is covers standardization of the methods for assessing the durability of SFRM. In Korea, more than 90 percent of SFRM are used indoors. So This study is to decide proper test method through investigation and examination of effect factor to performance of fire-resistant structure and applicable test method.

This study was attempted to standardize preparation methods of Korean foods; Chigae (Stew) such as Deonjang chigae (soybean stew) and Kimchi chigae (Kimchi stew). We followed cooking methods by using cookbooks, food service operation recipes, materials distributed by commercial food restaurants from their own experimental kitchens, and home recipes. Before this recipes were standardized, we thoroughly analyzed and modified them. The total yield and portions were determined together with material weights and procedures. And we evaluated food made by standardized recipes for acceptability, by taste panels from Sookmyung Women＇s University. It concluded that yield volune for doenjang chigae and kimchi chigae after cooking for 10 persons was 3 kg, optimum service temperature was 7$0^{\circ}C$, preparation time was 50 minutes, service volumes by one person was 300 g. This presentantion for the above on food materials and material weights, preparation methods as well as cautions and references are attached in this research paper.

본 연구에서는 현재 국내 목조건축에서 벽구성 재료로 많이 사용되고 있는 수입 OSB(배향성 스트랜드보드)를 국산 합판으로 대체하기 위해 OSB와 국산 합판의 못 접합부 전단성능을 비교 검토하였다. 주부재(잣나무)와 측면부재(OSB 합판)의 섬유 방향성(평행 직각)에 따른 전단성능은 합판에서 현저하였다. 결과, OSB와 합판 모두 현행 국내 기준인 못 접합부 기준 허용전단내력을 만족하는 것으로 나타났다. 그리고, 표면층에 MLH(열대산 활잡목)를 사용하고 7ply 구성한 합판(P-4 type)은 OSB보다 섬유방향에 관계없이 큰 전단성능을 나타냈다. 전반적으로 측면부재로서 합판을 사용할 경우 주부재에 대하여 섬유방향을 직교되도록 구성할 경우, 평행방향 구성보다 큰 전단성능을 발휘할 수 있음이 확인되었다.

폐콘크리트의 재활용에 대한 연구는 주로 고품질 순환골재 생산에 포커스를 맞춰 연구가 진행되어 왔으며, 그 결과 순환골재 국가표준을 제정하는 등 적극적으로 사용할 수 있는 환경이 조성되었다. 하지만 폐콘크리트 미분말의 경우, 그 활용에 대한 연구가 국내에서 많이 수행되었음에도 불구하고 상용화로 이어지는 획기적인 기술은 아직 발표되지 않은 실정이다. 최근 해외 주요 선진국에서는 폐콘크리트 미분말을 클링커나 시멘트의 원료로 사용하는 기술에 대한 연구가 활발히 이루어지고 있다. 이와 같은 배경에서 본 연구에서는 시멘트-콘크리트 산업의 탄소중립을 위한 폐콘크리트 미분말의 고부가가치 재활용 기술 및 상용화 동향에 대한 사례조사를 실시하였다. 폐콘크리트 미분말의 고부가가치 리싸이클을 위해서는 골재와 시멘트 페이스트의 완벽한 성분 분리가 필수적이며, 해외 주요국에서는 연구 개발 단계를 넘어 클링커의 원료 또는 시멘트의 혼합재로 사용하는 것에 대한 상용화 및 표준화가 진행 중이다. 따라서, 국내에서도 탄소중립의 관점에서 폐콘크리트의 재활용을 위한 연구 개발 및 표준화에 대한 논의가 시급하게 이루어져야 할 것이다.

Due to the industrialization and urbanization, the transport of hazardous materials increases, which rises possibilities in occurring prospective accidents in terms of hazardous material transport as well. This study applied the model developed from the previous research to analyze the scale of damage areas from the accidents related to hazardous material accidents, as well as suggested a method to measure automatically the scale of accident including casualties and environmental damage based on the guideline which suggests the quantities of hazardous materials exposed from an accident and was defined in the study of standardization for hazardous material classification. A buffering analysis technique of Geographic Information System (GIS) was applied for that. To apply the model which evaluates the scale of population and exposure to environment on each link, rail network, zones, rail accident data, rail freight trips, and locations of rivers etc were complied as a database for GIS analysis. In conclusion, a method to measure damage areas by the types of hazardous materials was introduced using a Clip and a Special Join technique for overlay analysis.

Paper angle, environment friendly packaging material, has been mainly used as an edge protector. But, we have perceived its application to package design of heavy product such as strength reinforcement or unit load system (ULS) in the future. Above all, understanding of buckling behavior for angle itself and compression strength and quality standard have to be accomplished for the paper angle to be used for this purpose. The purpose of this study was to elucidate the buckling behavior through theoretical and finite element analysis, and to develop compression strength model by compression test for symetric and asymetric paper angle. Based on the result of theoretical and finite element analysis, increasing rate of buckling of asymmetric paper angle was higher as applied load level was bigger and/or the length of angle was longer than that of symmetric paper angle. Decreasing rate of minimum principal moment of inertia was remarkably increased as the extent of asymmetric angle is bigger, and buckling orientation of angle was open direction near the small web. Increasing rate of maximum compression strength (MCS) for thickness of angle was smaller as the web size was bigger in symmetric angle. MCS of asymmetric angle of $43{\times}57$ and $33{\times}67$ was decreased $15{\sim}18%$ and $65{\sim}78%$, and change of buckling was increased $12{\sim}13%$ and $62{\sim}66%$, respectively.
