The purpose of this study is to identify the characteristics of the Dressing-Room lay-out in brand-apartments as the strategy for the differentiation. The 441 floor-plans are collected by searching web-sites of the 5 main construction companies. The major findings are summarized as follows: (1) The Dressing-Rooms are designed in the 331 cases among 441 the floor-plans including the Dressing-Room are generally over 30 Pyeong(about 99 square meters). In addition, the entire cases above 60 Pyeong(about 198 square meters) include the Dressing-Room. (2) The size of the Dressing-Room is increased in proportion to the square meter. However, the ratio is the small range of fluctuation. (3) The types of Dressing-Room units are classified 4 categories : a dressing-room joined powder room, a dressing-room separated from bathroom, a dressing room without powder room, a powder room centering with dressing room and bathroom.

The 1st International Conference on Magnetic Refrigeration at Room Temperature was held at Montreux, Switzerland during September 27-30, 2005. The conference was the first of its kind to bring together about 140 scientists and engineers interested in magnetic refrigeration in one place. The magnetocaloric effect was discovered in 1881, however, magnetic refrigeration at room temperature was demonstrated to be viable in 1997 Since then, R&D efforts toward magnetic refrigeration have been on the rise around the world, in both areas of systems and materials. The conference reflected the recent R&D trend in magnetic refrigeration at room temperature, which includes the use of permanent magnet instead of superconductor magnet, switch from reciprocating to rotary magnetic refrigeration system, development of magnetic materials based on transition metal elements besides rare earth materials such as gadolinium(Gd).

Heat and fluid flow in the motor block room of a motorized car is numerically simulated. The motorized car, composed of a motor block room and a passenger room, supplies additional Power to achieve the design speed. A motor block, a transformer, and a fan are equipped in the motor block room. Flow phenomena in the ducts on the motor block and power transformer are investigated. Also, the three dimensional heat and fluid flow in the motor block room is simulated to give a qualitative information of the flow characteristics.

A medical college is faculty which performs frequent experiments and holds lots of seminars for these reasons, this place was designed to exchange its concentration, taking its spatial psychology convenience and its functions into consideration. This space has been built up as the technological and multi-functional space to encourage it to accomplish special functions required by each of facilities, such as the president room, a main center of administration in the medical college, an audience chamber, an attached room, the room for alumni, preventive medicine and Micro biological diseases, a legal medicine lecture room, the room for basic medical science and a conference room.

This study has carried out in order to furnish the fundamental material to systemize the lecture room into multimedia in the future, by locating college lecture room as the subject of study, by compare and analyze on acoustic character in both before and after of each improvement. Thereby, now we are about to compare and analyze on physical character of room acoustics in both common lecture room before improvement and the modified multimedia-lecture room after its improvement. Observing the conclusion obtained through experiment, reverberation time in the modified 'lecture room after improvement' became shorter compare with the 'lecture room before improvement', definition and RASTI also improved to be suitable to lecture, and considered that it is able to elevate the intimacy with studying and teaching efficiency, as well.

This study compared the floor impact sound level of rectangular receiving room type to differed receiving room types to analyze effect of room mode. The floor impact sound level of master room were higher than the level of living room which resulted from room mode. The result showed that the level of low frequency bandwidth in the location varied with receiving room types were lower than general measuring point of rectangular receiving room.

I사 회의장은 실의 용도에 따른 실내음향특성에 대한 고려없이 설계, 시공되어 잔향시간이 길고 명료도가 매우 낮아 실내음향특성의 개선이 요구되어 왔다. 본 연구에서는 I사 회의장의 실내음향특성의 개선을 위해 실험 및 기하음향법을 이용한 시뮬레이션(simulation)을 수행하였다. 시뮬레이션을 수행함으로써 개선 안에 대한 음향파라미터 예측이 가능해졌고, 이로써 I사 회의장의 실내음향특성을 개선하기 위한 방안을 수립하였다. 그리고, 시뮬레이션의 결과에 대한 검증을 위해 시뮬레이션 값들을 실험치와 비교 평가하였다. 또한, 개선공사 후 실내음향 특성을 성공적으로 개선시킴으로써 본 논문에서 제안한 해석방법의 타당성이 입증 되었다.

우리나라는 IT 강국으로 관련 부품 등을 생산하기 위한 Clean Room 시설이 기하급수적으로 증가하고 있으나, 열·연기 확산에 대한 과학적인 분석이 멀티플렉스, 할인점, 고층 빌딩 등에만 국한되고 있어 생산시설에 대찬 적극적인 검증이 이루어지지 않고 있다. 또한 Clean Room 시설이 가장 많은 국가로 우리나라와 더불어 미국, 일본, 대만 정도에 지나지 않아 국제적으로 Clean Room에 대한 많은 방재기준 제정 및 연구가 미흡하다.(중략)

Many trials have been used to model room impulse responses, all attempting to provide efficient representations of room acoustics. The traditional model designs for room impulse response seem to fail in accuracy, controllability, or computational efficiency. In time domain, a room impulse response is generally considered as the combination of three parts having different acoustic characteristics, initial time delay, early reflection, and late reverberation. This paper introduces new learning hybrid model for the room impulse response. In this proposed model, those three parts are modeled using different models with learning algorithms that determine the length or boundary of each model in the hybrid model. By the simulation with measured room impulse responses, it was examined that the performance of proposed model shows the best efficiency in views of both the parameter numbers and modeling error.
