조선 개국 시 영조된 사직단은 일제강점기를 거치면서 사직공원으로 고착화되었고, 최근 복원에 대한 노력이 진행되고 있다. 통시적으로 분석된 사직단의 변화 내용은 다음과 같다. 첫째, 한 나라의 중요 국가제사를 지내던 장소로의 입지를 확보하고 강화되었던 조선시대 태조에서 일제강점기 이전까지의 시기이다. 태조대에 인왕산 자락에 축조했으며 임진왜란 시 소실된 후 영조 대에 제례시설이 완비되었다. 그러나 1908년 일제의 간섭이본격화되자 공간 멸실과 제사가 폐지되었다. 둘째, 일제에 의해 공원화가 진행되어 고착화된 1910년부터 1944년까지이다. 공원 관련 시설과 경계부에 이질적인 건축물이 들어섰고, 단 영역 재실 사직단문이 고적과 보물로 지정되기도 하였다. 셋째, 해방 이후 1984년까지 이질적 성격의 동상과 기념비, 건축물이 축조되어 혼재된 장소성을 지니게 된 시기이다. 사직터널의 개설로 사직단 문이 2번에 걸쳐서 이축되기도 하였다. 넷째, 사직단의 역사성과 상징성을 회복하기 위한 노력이 진행되고 있는 1985년부터 현재까지이다. 사직단 권역의 복원 계획이 진행되고 있으나 주민에 대한 반발로 난항을 겪고 있는 시기이기도 하다. 향후, 사직단의 원형 회복을 위한 복원을 위해서는 발굴조사를 통한 면밀한 고증과 주민의 이해가 함께 진행되어야 한다.

With the building is higher and higher, the stack effect is more and more remarkable. The stack effect accompanies many problems in high-rise building such as draft, troublesome in door opening, uncomfortable noise, contaminants dispersion, etc. In this study, the air movement and accompanied contaminants dispersion by stack effect in high-rise building, and diluting the contaminants concentration were analyzed. The analysis was performed for high-rise residential building in Seoul, Korea and the network simulation method was used. The results show that the indoor contaminants concentration and air movement caused by stack effect have interdependent relationship.

대형 냉장고의 경우 내부구조가 복잡하고 냉장고 문을 열고 닫을 때 냉장고 내부에 온도편차가 발생하며, 또한 진동에 의한 흔들림이 발생하게 된다. 이러한 다양한 원인에 의하여 간헐적으로 부품간 마찰에 의한 이상소음이 발생하기도 한다. 따라서 본 연구에서는 이러한 이상소음의 원인과 메커니즘을 실험적으로 분석하고 이것을 줄일 수 있는 가능성에 대하여 제안하고자 한다. 이상 소음을 구현하기 위한 실험장치를 구성하고 냉장고 문의 열림과 닫힘에서 발생되는 변형량 분석과 온도 변화에 따른 내부 압력변화를 측정하여 소음발생의 주요원인에 대하여 분석하였다. 또한 설계초기 단계에서 적용이 가능한 소음저감 방법론을 제안하였다.

After the development of printing technology since the 15th century and the rise of citizen consciousness in the 18th century, the library has taken a public concept. And after the 20th century, its role as a public library for the public was stressed, and as its spatial composition became miniaturized and specialized, its function changed from stacking and reading to various kinds including culture and service and is getting more complex beside the function of a library. Thereupon, this study aims to figure out the limitations of public libraries' opening years shown in advanced researches and understand the current status of spatial composition by complexation with the subjects of five public libraries opened after the end of December, 2006 in order to examine their tendencies of complexation and the characteristics of spatial composition by the complexation of public libraries. As a result, the present public libraries have at leaser more than two spaces with complex functions. According to the result of analysis on the types, locational relations between spaces showed the mixed type the most. In the types of building allocation, the building integrated type had a higher percentage than the separated type. About the types of entrance, the one common door type was fewer than the two separate door type. In the analysis on the types of the interior line of flow, the common type was similar to the dispersed type, and it is thought to be resulted from spatial composition rather than the preplanned line of flow.

This study finds out the aged consumers' needs on the developing elderly friendly and sensitive bathtub. This bathtub focuses on enhancement of multi-senses and enhancement of health, safety & convenience during bath. The enhancing multi-senses would have four functions; therapy with color and aroma, the massage with micro water bubbles, the visual and auditory with TV & cinema, and the auditory with music and radio. Also, enhancing others of bathtub would have seven functions; emergency bell, blood-pressure check system for health condition, water temperature indicator, keeping water warm, reading a book in that, and controlling of house entrance door and a getting the phone during bath. The aged consumers' needs find throughout a questionnaire survey, and 497 data was analyzed. The main results are as follow. They consider a full bath behavior as a healthcare. They have an intention to purchase or use the elderly and friendly bathtub, and they prefer using it in common facilities to using it at home. They highly need health related function of bathtub, which are massage (64.4%), blood-pressure check system (55.1%) and aroma therapy (45.7%). The emergency bell (67.0%), keeping water warm (62.2%), and water temperature indicator (49.7%), related to safety & information function of bathtub, are needed. Also, they think tolerance for error and low physical effort in bathtub design alternative, opening door and inside sitting support, to be important.

The purpose of this study is to discuss Joseon dynastyis first perspective on the Western-style Court Costume which was newly introduced to Joseon through the problems receiving the credential that Japan had sent in new style. For this study, the records of Joseon and Japan at that period have been analyzed. The followings are the results of this research; First, a critical argument on the Western-style Court Costume occurred just before the Port Opening because whether wearing a western costume was the key factor in Joseon dynastyis receiving the credential that Japan had send in new style. Second, Japan received western costume as its domestic courtesy system by establishing the Court Costume of Civil servants in 1872 and consequently Japan established new ceremony procedure of western-style bow in 1875. Third, Joseon dynasty officially opposed to the Western-style Court Costume when Japan sent the credential, because the western costume selected by Japan had beenregarded as that of western barbarian at that time in Joseon. Accordingly, it seems reasonable that before the introduction of western costume into Joseon dynasty, an open-door policy for the West had been a prior settlement for Joseon dynasty regardless of the details of Western-style Court Costume. And also, the pride of civilization of Joseon dynasty, which has been used to express Joseon dynastyis identity as Joseon-centrism, had to be converted before the open-door policy. Ultimately, it could be inferred that the reception of the Western-style Court Costume had been raised as the political and diplomatic problems in the circumstances when the submissive relationship in the traditional Eastern- Asia had been forced to be converted to modern sovereign international relationship.

연구목적: 고층 건물 화재시 제연구역이 효과적으로 보호되지 않으면 수직피난경로에 연기나 화염이 유입되어 대피가 어려워진다. 국가화재안전기준에서는 제연구역에 차압 및 방연풍속을 공급하여 능동적으로 연기 유입을 억제하고, 제연구역으로부터 옥내로 유입되는 공기는 옥외로 배출되도록 하고 있다. 본 연구는 유입 공기의 배출로 인한 문제점을 확인하고 성능개선 방안에 대하여 알아보고자 하였다. 연구방법: CONTAM 프로그램을 사용하여 기본조건과 변경조건으로 시뮬레이션을 수행하였다. 연구결과: 밀폐된 복도에서 유입 공기가 배출되면 제연구역에서 과압이 발생하여 개방력을 초과하였고 유입공기가 배출되지 않는 층 에서는 방연풍속이 미달하였다. 결론: "차압 배출댐퍼" 적용, 배출댐퍼 2개층 동시 개방, 복도와 옥외 사이 자동식 창문 설치로 유입공기의 배출 성능이 개선되었다.

Objectives: Methyl bromide is a highly toxic substance that can cause systemic poisoning, neurotoxicity, pulmonary edema. Methyl bromide is a widespread fumigation agent used for import and export quarantine, but there is little data on exposure assessment of workers participating in such fumigation. Therefore, this study aims to investigate the exposure level of methyl bromide among workers and the concentration distribution of methyl bromide in the workplace during fumigation. Methods: For this study, one wood tent and one container fumigation area in Pusan, and one wood tent fumigation area in Incheon were investigated over three months from June 2001. Results: Methyl bromide exposure levels for container fumigation workers were from undetected to 1.86 ppm and from undetected to 2.28 ppm for tent fumigation workers as an 8 hr TWA. After opening the container door, the methyl bromide concentration in the container decreased rapidly over time, but the concentration remained over 1 ppm even after about one hour. The concentrations around the tent during its removal were highly affected by wind, but were detected in a range from undetected to 11.97 ppm. Conclusions: This study confirmed that both container and tent fumigation caused workers to exceed the exposure limit of 1 ppm as an 8 hour TWA. In particular, it could be confirmed that a situation exists in which the worker may be exposed to high concentrations of methyl bromide when opening the container or removing the tent due to the nature of the work. Therefore, it is very important to improve working methods and to wear appropriate personal protective equipment.
