In the course of modernization coupled with industrialization and urbanization. Maru or wooden floor and Teachong or great hall of Han-ok or traditional Korean housing has experienced functional as well as physical changes to a remarkable degree. The author made an analysis of the transfiguration of Maru/Taechong space(M/T) with relation to: 1)Madang or yard. 2)Anbang or inner room, 3)Hyon-kwan or vestibule. 1) In relation to Madang, interiorization of M/T by way of setting sliding glass doors has begun to appear. 2) In connection with Anbang, division of role/function is being observed as far as family entertainment and reception of intimate friends is concerned. 3) Owing to wider acceptance of Hyon-kwan space as a buffer zone system, the advent of Keo-sil or living room is thought to be facilitated. The analysis, however, does not say that Keo-sil of modernized Korean housing might well be interpreted as the mere extension type of M/T of the vernacular housing.

In this paper, the intoner noise reduction for subway railroad vehicles was studied by improving transmission loss of carbody panels and side doors, and on-line tests were conducted to examine the exterior noise levels at various running conditions. Also the transmission loss for design candidates of the carbody specimen was measured in two reverberation rooms. From the results of the tests, side door gap is the most dominant factor affecting the Interior noise level of subway railroad cars with a sliding typed side door. The next one is revealed to transmission loss of a floor panel. To improve the transmission loss of the carbody, many activities were conducted such as, treatment of resilient and sound-absorbing materials and reducing the gap of the side door by adopting a brush and rubber, etc. The estimated interior noise level for modified car which is designed with improved carbody panels is lower than original car by about 5㏈.

This study is to analyze the transfiguration of the plan of the Japanese-Western eclectic houses in the process of the change in the living style and modernization. Twenty four Japanese-Western eclectic houses. which were located in Teagu Province and constructed during the period from the end of 19th century to the year 1945. were surveyed and analized about the original plans and the process of their spatial tranfituration. The results of this study are as follews 1) In the original plans. the bathroom, toilet and entrance hall in the residential space and HUSMA(wooden sliding doors) for separation of the rooms had been installed. 2) After the Liberation. the rooms of the residential space had been transfigured from TADAMI. JASHIKI. kitchen and toilet etc. to ONDOL. ANBANG. kitchen and toilet etc of the Korean traditional style. From 1980's they composed of living room, dining room and entrance hall of the Western-style. 3) From the liberation to 1960's. each room of residential space had been transtigured greatly form the Japanese style into the Korean style. Thus as the entrance hall. bathroom and TADAMI has been disappeared. DNDOL and MARU reappeared. Since 1980's bathroom diningroom and entrance hall ef the Western-style have recomposed in their residential space. But ANBANG is still used as a major living space in the surveyed houses.

전동차 출입문은 포켓 슬라이딩 도어, 아웃 슬라이딩 도어, 플러그 도어로 구분된다. 현재 국내 전동차의 표준규격으로 제시되어 있는 포켓 슬라이딩 도어는 철도차량이 고속화됨에 따라 소음 및 외풍의 차단이 어려운 단점이 있으며, 아웃 슬라이딩 도어 역시 소음 및 외풍차단이 어려운 시스템이다. 반면에 플러그 도어는 최근 철도차량이 고급화됨에 따라 고속철도에 적용되던 출입문을 전동차에 적용하면서 쓰이게 된 도어시스템으로 승차감 개선에 소음이 중요한 위치를 차지함에 따라 소음에 강한 플러그 도어 시스템이 주목받고 있다. 이러한 이유로 차세대전동차에 적용할 목적으로 전기식 플러그 도어를 개발하여 시험 진행 중에 있다. 플러그 도어를 구성하는 하부 부품으로는 출입문 제어 장치 (DCU : Door Control Unit), 모터, 스크루 기어, 볼 너트, 레일, 리미트 스위치, 각종 전기 장치, 비상 수동 개폐장치, 코디네이션 바 등이 있는데 이중 DCU는 전동차 출입문을 개폐하기 위한 제어장치로 량당 8개인 전동차 출입문이 동시에 열리고 닫히기 위해서는 각 출입문간의 인터페이스가 필요하며, 승객의 승하차와 직접적으로 관련되어 있기 때문에 신뢰성 및 안전성 확보가 매우 중요한 시스템이다. DCU의 기능으로는 자동 문 여닫음 제어, 출입문 제어 및 장애 감지, 출입문 상태 제어, 저전압/고전압 감시 등이 있으며, 본 논문에서는 전기식 플러그 도어에 적용하기 위해 개발된 DCU의 기능, 개발요구사양, 시스템 구성 및 시험결과에 대해 논하고자 한다.

In this study, by comparing the development and the space types of local and foreign flexible apartments, basic data will be derived for the development of various flexible types of apartments in Korea. A total of 60 unit plans, including 30 domestic cases and 30 overseas cases of flexible apartments, are analyzed for this study. In terms of the unit plan types, Korean apartments usually had a wide front bay with shallow depth, placing more rooms on the front bay; whereas foreign apartments tend to have various unit plan types: (1) a narrow front bay with deep depth, (2) a wide front bay with shallow depth, and (3) variegated open-plan types. Many apartments in foreign countries had a double-layered structure with the. upstairs and downstairs areas. In terms of the flexible types, many Korean apartments achieved interior flexibility using non-bearing wall or sliding doors; whereas foreign apartments had a flexible space by separating the support elements and the infill elements. There was found to be a close relationship between the location of support elements and the variability of unit plans. Support elements can be placed largely into three locations: (1) Between the front side bay and the rear side bay, (2) in the center bay of a unit plan, and (3) others. Depending on the location of support elements, various types of flexible unit plans can be created. Through a comparative analysis of domestic and foreign apartments, basic data that can be used for developing various flexible unit plans was derived.
