The objective of this study is to determine the ignition feasibility of a single shot, air-assisted gasoline fuel injector operated in a constant volume combustion chamber under atmospheric condition. A number of parameters has been selected for this experiments, such as dwelling time, spark gap position(r,z), spark electrode geometry, supplied air and fuel masses and spray cone deflector angle. On-site visual inspection of the instantaneous flame glow was chosen as one way to judge the successful ignition. In addition, chamber pressure and occasional photography were mobilized as for data recording. It was clearly observed that there was an entrainment air-fuel mixture toward spray axis from the spray formation and its development later on. The optimum ignition conditions were found for those parameters given above.

송국리유적은 1974년 비파형동검이 부장된 석관묘가 발굴됨으로써 학계에 알려지기 시작하였으며, 1975년부터 시작된 본격적인 발굴조사를 통하여 한반도 청동기시대에 획기를 이루는 중요한 유적임이 확인되었다. 그러나 지금까지 공개된 송국리유적 보고문에는 전체 평면도조차 제시되지 못하고 있어 유적의 전모를 이해하기 어려운 상황이다. 따라서 본고에서는 송국리유적의 보고서와 관련 보고문을 재검토하여 발굴된 전체 유구의 배치도를 작성함으로써 연구의 기초자료를확보하였다 그리고 이러한 내용과 개별 유구및 출토유물에 대한 분석결과를 최근의 발굴.연구성과와 비교 검토함으로써 송국리유적의 시기와 성격에대한 새로운 견해를 제시하였다. 송국리유적에서는 주거지, 부속유구, 저장공, 요지, 목책렬, 녹채, 굴립주건물지 등의 생활 유구와 석관묘, 옹관묘, 토광묘 등의 분묘 유구, 그리고 대지조성면과 같은 대규모 토목공사의 증거들이 확인되었다. 이들은 유구의 분포 양상이나 유물상의 유사성 등을 통하여 볼 때 동일시기에 해당하는 것으로 판단되는데, 구체적인 시기는 방사성탄소연대 측정치에 의하여 대략 B.C. 850-550년의 범위로 산정되었다. 한편,송국리유적에서는 논농사의 집약화를 통하여 생산량을 증대시켰으며, 이러한 경제력을 바탕으로 유력자또는 유력 집단이 등장하게 되었을 것이다. 그들은 자신의 우월적 지위를 유지하고 더 많은 잉여생산물을 안전하게 보호하기 위하여 방어 취락을 형성하였으며, 이를차지하기 위한 빈번한 전쟁이 있었던 것으로추정된다. 그러나 어느 정도의 안정적인 삶을 유지하였으리라 생각되는데, 이는 인구 증가에 의한 주거 공간의 확대를 통하여 짐작할 수 있다. 결국 송국리유적은 이러한 과정을 거쳐 주변의 여러 취락과 관련을 맺으면서 그 정점에 위치하는 중심취락으로 성장하였을 것이다.

The purpose of this study is to improve design method for renovating an environmental friendly residential space where nature and humans could coexist. In the present study, five deteriorated multi-family housing complexes have been selected and one hundred and thirty eight dwellers have been asked about ecological important factors through the questionnaire. This study presents the adaptable solutions, such as are the enlargement of unit space or area, the renovation of facade, the functional change for dwellings on the ground level, the open piping of circulation systems, the expansion of community facilities(include greenarea), the build up of spatial hierarchy and the housing development set reuse planning forth as a premise, for the aspects of dwelling unit, building block and site planning.

This study was carried out to Identify wood and charcoal segments, which were excavated in 1994 at the Seohaean highway construction site along the western coast of Korea ; Tuntaeri, Hwasunggun. We identified the objects excavated at the fire places of the Tuntaeri dwelling sites (early Koryo period ; A. D. $11\~12C$) ; charcoal pieces and 1 wood segment, which was used for the handle of a metal hook. Chestnut(Castanea crenata), deciduous oaks(Quercus spp.) and maple(Acer app.) were identified from the charcoals, whereas the wood segment as willow species(Salix spp.). These species seem to represent warm and wet climate in the middlewest Korea during $11\~12C$.

This study examines the general reuse plan for deteriorated multi-family housing (apartrtments) in the urban fringe of Taegu City. The apartments which were built in the 1970's have to be improved. It is necessary to carry out the actual investigation for alternatives of reconstruction or reuse. From the above point of view, the study lays its purpose to find pertinent directions for the reasonable reuse plan, and gets on as follows; 1) Analize the residential state for users' needs of detoriorated aprtments through an investigation. 2) Synthesize the experts' opinions about matters related to reuse planning through a questionnaire. 3) Suggest the general solutions in three areas; unit dwelling, housing site, equipment and facilities, Finally, in the future housing development projects, concepts of reuse planning should be reflected beforehand.

This Study analyzed about various factors affecting preference of Silver Town. Especially, the Study shows how Individual peculiarities and the realization of decrepit Service and facilities have on preference of Silver Town. According to analysis, the site location, Economics and Safety have a positive effect on the preference of the Silver Town. On the other hand, Investment, pleasant environment and convenience have nothing to do with the preference of the Silver Town. Also, the Study shows that if someone realizes that medical service is the most important thing in the essential service, they prefer the Silver Town. If someone realizes that asset management service is the most important thing in the essential service, they don't prefer the Silver Town.

산림을 주 서식지로 이용하는 쇠큰수염박쥐(Myotis ikonnikovi)의 서식지 특징에 관하여 연구하였다. 안개그물을 이용한 포획조사를 통해 확인된 쇠큰수염박쥐 서식지는 비교적 수령이 오래되고 흉고직경이 굵은 활엽수가 우점하는 숲으로 평가되었다. 소형무선추적장치를 통해 쇠큰수염박쥐의 잠자리는 주로 활엽수의 수피 틈, 꺾어진 줄기의 틈, 옹이 기둥 접합 부분의 틈 등으로 확인되었다. 낮동안 이용한 잠자리는 포획지점으로부터 35~584 m 이내에 위치하였으며, 개체당 잠자리는 1~5일간 이용하였다. 쇠큰수염박쥐와 같은 산림성 박쥐류의 다양성을 높이기 위하여 산림내 다양한 먹이자원이 풍부하고, 이용가능한 다수의 잠자리가 확보될 수 있는 산림서식지 관리방안이 요구된다.

As environmental problems and water-shortage phenomenon become a global issue, many states look for the effective method to use water resources. So, decentralized rainwater management is recognized as a new water management system that rainwater can be infiltrated and used on-site. But it is little difficult to build a park, lake, and forest for evaporating rainwater in city because the land price of city is very high. In order to build an excellent infiltration system for a dwelling and a park in Korea, KICT has developed Linear infiltration system. This infiltration system is consist of first flush treatment, storage and infiltration, overflow control system. These elements are connected closely and working as a combined system. A storm sewer can be changed by the linear infiltration system. This study is to show real application idea about Linear infiltration system with improving some detail in apartments. For this purpose, we devide application idea into the artificial ground and the natural ground and each ground type, suggest a method to cooperate with the other landscape and linear infiltration system. Through this study, we came to recognize a recognition difference of an expert and a commoner about decentralized rainwater management.
