This research aims to establish the size standard of university library's user space, and present the standard and method to calculate total area required in the planning of new building construction and remodeling. Nine university libraries newly constructed or remodeled since 2000 were selected among the libraries of large scale universities with more than 10,000 enrolled students as the target libraries in this research. The target libraries were classified into A group (five cases partially remodeled) and B group (four cases newly constructed or fully remodeled) on the basis of the change of times. A university library can be divided into three spaces (user space, administration space and public space). This research classified the reading room in the user space into bookshelf zone, reading zone, information/office zone and hall/other zone, and analyzed area ratio according to each zone. B group's bookshelf zone decreased 12% more than A group, and B group's reading zone increased 10% more than A group. However, there was no big change in the area ratio of information/office zone and hall/other zone. This can be interpreted that university library changes from book and archive preservation-oriented space to user-oriented space. This research presented a proper reading room area calculation method, based on the capacity of books, by reflecting such a change. Each zone's standard was set up through classification of domestic and international standards, based on which, the calculation method of university library's total floor area required was presented. The reason why there was difference in university library's total floor area required according to domestic standard and international standard was that the number of enrolled students per seat in the reading room was different. The area calculation methods presented in this research can be utilized as useful data upon planning university library construction or remodeling.

본 연구는 마케팅 관점에서 국립자연휴양림의 객실가격 전략을 개발하고자 실시하였다. 분석방법은 객실유형(숲속의집, 산림문화휴양관) 및 객실규모(4, 5, 6, 7 인실)에 따른 가격민감성(PSM) 분석을 적용하였으며, 6개 국립자연휴양림에서 236명의 객실 숙박이용객을 대상으로 현지설문조사를 실시하였다. 그 결과 자연휴양림 객실규모에 있어서는 객실규모가 클수록 가격민감성이 높았으며, 객실유형별로는 숲속의 집이 산림문화휴양관 보다 가격민감성이 높은 것으로 나타났다. 또한 현재 성수기 객실가격은 6인실과 7인실 산림문화휴양관을 제외한 모든 객실에서 가격수용대 내에 포함되어 있는 것으로 나타났다. 이들 객실의 판매를 촉진시키기 위해서는 적정수준의 가격 인하를 검토하거나, 가격인하가 용이하지 않을 경우 고객이 지각할 수 있는 객실시설물 고급화 등 가격 이외의 다른 가치를 높이기 위한 전략이 필요할 것이다.

The performance of fan for engine room of ship is absolutely important when it take into consideration work efficiency, work condition, and the performance of various equipments. Fan performance test should be carried out during sea trial to satisfy owner's requirement as above mentioned. We have considered various values to affect fan test result. In here, various values are to be silencer, fan inlet shape, and arrangement of fan room. In general, the shapes of fan inlet is overall circular type because of the shapes of axial fan. So, all vessels built at SHI have been applied fan inlet of circular type. And now, in order to reduce sound of noise from supply fan, big silencer often has been installed at high value vessels. In this case, the capacity of supplied air can be insufficient due to silencer which is an obstructer about air flow. In this paper, we have studied the performance of fan through comparison between a circular shape and a square shape of fan inlet. We also compare with CFD results and experimental results.

최근 발생한 대형참사의 근본원인은 $\ulcorner$안전수칙 미준수$\lrcorner$ $\ulcorner$관리자의 부주의$\lrcorner$, $\ulcorner$책임의식의 결여$\lrcorner$ 안전과 관련한 가치관의 부재에서 유발되었으며 이의 가장 큰 원인으로는 전반적인 인명 경시 풍조, 안전무시, 무사안일주의, 이기주의 등 여러 가지 복합 요인이 있으나, 안전 교육과 공간의 미비 등이 큰 문제점으로 지적되어 왔다. 이에 본 연구에서는 전 국민의 안전의식변화를 위하여 체험교육을 할 수 있는 공간을 제안 하고자 국내외의 체험관의 사례를 비교 분석하여 구체적 대안을 제시하였다. 결과, 지역실정과 재해유형에 맞는 적정규모의 안전체험관 건립의 당위성을 시 도가 단계적으로 추진해 나가고, 국고가 지원될 수 있도록 중앙정부에 적극 건의하여 정책에 반영될 수 있도록 함으로써, 적어도 시도별로 $1{\sim}2$개소 정도의 유사 안전체험관을 건립, 국민의 안전문화 의식을 제고시켜나가야 할 것이다. 그리고, 건물규모 면에서도 재정여건 등을 감안해 볼 때 외국의 안전체험관처럼 거대규모의 시설을 갖출 수는 없으나, 우리나라의 제반 실정에 맞는 재해, 재난, 사고유형별 다양한 체험습득을 위한 시설과 장치가 마련되어야 하며, 생활안전과 연계된 교육 프로그램의 개발과 적용, 풍부한 도서 및 영상자료를 통한 지식과 정보의 제공의 공간으로서 건립되어야 할 것으로 분석되었다.

As a rapid supply of a culture facility the change of living style bring on needs about storage space in the residence space. This study choose Hong Je Dong-Byuk San 4 type apartment house which was built in 1990 as research target and we selected 4type of a total 12house and we choose LDK as a research target that is high in a requirement and utilization other space is excluded in this study. We can expect that the apartment house will be differed with area of living space of apartment house in the requirement of storage space. Small apartment house is requried various storage planning because of confined living space But big apartment houses required storage planning of simple type because it have already storage space. So we have to do efficiency storage planning because of limited space in the apartment house. Base on this results we will show storage space according to the type of pyeong. So this study show proper storage type according to the scale of apartment house,.

The intake noise of an automobile induced by firing of an engine accompanies acoustic resonances of ducts of an intake system. Conventionally, the adoption of the Helmholtz type resonator was one of possible ways to eliminate the booming noise due to acoustic resonances of air ducts. Although the Helmholtz type resonator is convenient to attenuate the intake noise of an automobile, the usage of the Helmholtz type resonator requires cost increase or big engine room space. Therefore, reduction of the number of the resonators or the volume of the resonators is essential to increase the value of an automobile. To meet these requirements, other types of resonator are suggested instead of the Helmholtz type resonator. The effectiveness of the suggested resonators is compared considering noise reduction ability, effect to the engine performance and size of each resonator.

Now days, as the consideration of sound environment is getting important, method of physical measurement such as reverberation time and sound pressure level becomes common. However, such method cant include subjective sensation such as personal emotion and feeling, evaluation. So there is a limitation to make the most optimized sound environment. Therefore, in the present experiment, I improve big indoor gymnasium that has sound defect because of too long reverberation time. After that, I conduct the auditory sense evaluation of human psychological response. From the experiment, I will make research into sound satisfaction rate about the subject space and response of each item. As well as, I will present the result as basic database of sound environment improvement experiment of indoor gymnasium.

As the building is becomes bigger and larger, it can lead to big damage in case of fire. Also, tunnel, machine room and underground joint are spaces that can cause high temperature fire above 1,350℃ in case of fire. Therefore, a refractory material is need that can be withstand in high temperatures for long time. One side, the composition of oyster shell is CaCO₃ of 90% or more. It is expected that it will be possible to use it as a high calcium natural material which is the material of the refractory board. According to, Study on bending, compressive strength of mortar according to temperature and heating time change using oyster shell as aggregate the most commonly occurring particle sizes form 2.5mm to 5mm.

It is important to control material flow in shipbuilding as it decides the productivity of production, cost and period of production. The weight of material in a big shipyard is even more one million tons. The results contained in this paper can provide the valuable information on the effect of reduction of cost and competitive power. The intention of this paper is to let ship builders pay attention to material flow. This paper refers to other manufacture's methods to improve their material flow and also give one example to show how to pursue to improve material flow in a shop. We have still lots of room to improve material flow.
