This project is to establish an annex clinic center under 5 floors with gross floor area of 3,000 Pyeong behind existing Chosun university Hospital main building with 600 beds. The goal of the design is connecting the new clinic center with the existing main building and completing a combined hospital that has synergy effects. Given the old condition of the hospital and characteristics of the ground, I tried to embody the image of Medical Pulse, which is very alive with strong pulse, and suggest vision of 21st century hospital. First, one main entrance as a combined hospital. For optimum access and functions, I used the entrance of existing building as the only main entrance of new combined hospital, rearrange the road in front of the main building and improve traffic system, and upgrade the image and function of combined main entrance by planning new atrium united robby that makes link to the main building easier. Second, section planning considering the optimum functions and convenience. I established 4 floors linking functionally with the existing building, minimized vertical traffic line, and enhanced convenience through barrier free environment, which is a horizontal traffic line without barriers, crucial to hospital. Third, combined zoning generating synergy effects. I linked sterilizing room with logistics center by operating room and service bridge, and arranged central treatment department horizontally, Also, by horizontally arranging cancer center and department of nuclear medicine close with PET and cyclotron center, I established identity of specialized departments.

산업헉명 이후 유리와 철의 이용은 넓은 개구부를 지닌 대형공간을 지닌 건축을 가능케 하였고, 1970년대 이후 새로운 건축양식의 추구라는 시대적 요구는 아트리움의 건축적 응용을 확산하게 하였다. 아트리움은 다층건물의 유리로 덮힌 대형공간으로 건물의 중심적이고 내부적인 공공의 공간이다. 대형공간으로서 아트리움의 가장 큰 특징은 넓은 채광창을 통해 실내로 유입되는 태양광에 있다. 넓은 채광창은 사람들에게 시각적인 개방감을 제공하며, 또한 많은 채광량으로 식재에 의한 조경이 가능해 외부공간과 같은 분위기를 연출하면서도 비·바람·추위 등으로부터 보호되는 쾌적한 온열환경을 제공하고 있다.

This paper describes the smoke filling process of a fire field model based on a self-developed SMEP(Smoke Movement Estimating Program) code to the simulation of fire induced flows in the two types of atrium space containing a ceiling heat flux. The SMEP using PISO algorithm solves conservation equations for mass, momentum, energy and species, together with those for the modified k- epsilon turbulence model with buoyancy term. Compressibility is assumed and the perfect gas law is used. The results of the calculated upper-layer average temperature and smoke layer interface height has shown reasonable agreement compared with the zone models. The zone models used are the CFAST developed at the Building and Fire Research Laboratory NIST U.S.A. and the NBTC one-room of FIRECALC developed at CSIRO, Australia. The smoke layer interface heights that are important in fire safety were not as sensitive as the smoke layer temperature to the nature of ceiling heat flux condition.

The purpose of this study was to evaluate the usability and satisfaction of space to which positive elements in Leed-Certified Office Building are applied. The study was conducted using the three-step approach. The first step was to understand the building and identify the issues which included the analysis of floor plans, documentations, and the interview with designers and facility managers. The second step was FGI(Focus Group Interviews), which were conducted with mixed employees of rank and location of workplace. Finally, a web-based questionnaire survey was conducted on the 319 executives and employees. Methods of analysis used were quantitative analysis of questionnaire, qualitative analysis of open ended free-answer, and FGI in the second step. Satisfaction, preference, and comfort level were studied using cross tab, co-relation, ANOVA for quantitative analysis. The results of this study are as follows: First, lobby and atrium are representative elements that are functioning positively and it is recognized as sustainable spaces being utilized by users. Second, there are several dead spaces like green shaft, roof garden and sunken space although they can contribute to Leed-certification. Third, there are some problematic spaces such as the O.A. room and the urinals even though they contribute to the Leed-certification.

This paper investigates the exhaust effectiveness of smoke, in the case of fire in a large atrium space. Numerical analysis was conducted to simulate transient fire growth in a test room, modeled by the Murcia atrium fire test. Various indices representing the exhaust performance of the exhaust system were obtained, such as the height of the smoke layer, and the instantaneous and accumulative capture efficiency of the smoke. The residual life time of smoke from the fire was also obtained, by injecting tracer gases at the fire location, depending on the airflow rate, and the location of the exhausts. The capture efficiency based on smoke concentration at the exhausts exhibits how much smoke can be removed by the exhaust system; whereas, the exhaust effectiveness based on residual life time indicates how rapidly the smoke can reach the exhaust locations, before being exhausted. The definitions and meanings of the indices to be used in representing the exhaust performance of a smoke exhaust system installed in a large space are discussed.

The architectural design of student circulation space has a pronounced influence on the educational function of a school building. Recent curriculum and new teaching methods have required the sufficient space provided for circulation and various circulation spaces in a school building, such as elevator, pilotis, bridge, atrium, deck, lobby and locker room. However excessive circulation space is wasteful form the standpoint of both initial investment and operation. This study aims to investigate new circulation patterns and functions, and to propose the adequate size in planning a school corridor. For this purpose, it explores the recent trends of the corridor planning represented in the excellent school facilities in 2002. and analyzes the newly-added functions In the school corridor : architectural in-between space, dwelling space for ordinary activities, space for educational media and auxiliary learning space. This research recommends that the corridor width be carefully planned according to the supposed functions in order to achieve the efficiency in the design of school facilities.

A base isolation system is widely used to reduce seismic responses of low-rise buildings. This system cannot be effectively applied to high-rise buildings because the initial stiffness of the high-rise building with the base isolation system maintains almost the same as the building without the base isolation system to set the yield shear force of the base isolation system larger than the design wind load. To solve this problem, the mid-story isolation system was proposed and applied to many buildings. The mid-story isolation system has two major objectives; first to reduce peak story drift and second to reduce peak drift of the isolation story. Usually, these two objectives are in conflict. In this study, a hybrid mid-story isolation system for a tall building is proposed. A MR (magnetorheological) damper was used to develop the hybrid mid-story isolation system. An existing building with mid-story isolation system, that is "Shiodome Sumitomo Building" a high rise building having a large atrium in the lower levels, was used for control performance evaluation of the hybrid mid-story isolation system. Fuzzy logic controller and genetic algorithm were used to develop the control algorithm for the hybrid mid-story isolation system. It can be seen from analytical results that the hybrid mid-story isolation system can provide better control performance than the ordinary mid-story isolation system and the design process developed in this study is useful for preliminary design of the hybrid mid-story isolation system for a tall building.

In the early twentieth century, many architects still practised eclectic design elements. Emergence of new building materials such as steel, concrete and glass were not yet found fresh roles in architectural design. It was Brussels that the use of modern materials gave rise to their new forms and gave influence to not only building skins but also spatial organization. Art Nouveau architecture is often seen as revolutionary and pioneering modern architecture against eclectic classicism prevalent in the 18th and 19th centuries. Despite the fact that some scholars point out that Art Nouveau is more a transient phenomenon than modern architecture proper, no one would deny that Art Nouveau carries a good deal of modern characteristics. This paper intends to show rather ambivalent perspectives upon Art Nouveau architecture. Although it insinuates overly dynamic nature in architectural languages, it does not hamper us from reading Art Nouveau as a vital component of modern architecture. Through a careful analysis of the early domestic designs of Victor Horta, it becomes evident that his work can provide modern architecture a meaningful alibi for its growth. Victor Horta's house design is well known to the public, both for his classical tastes and for its changing implementation. Horta's modern quality is never adequately recognized, partly due to his eye catching modern iron properties and sinuous ornamentation. This paper tries to offer an insight into the complicated stage set of the fin-de-$si{\grave{e}}cle$ through the work of Victor Horta whose influence has been immense in the making of modern architecture.
