The terms of the one-room dwelling began to attract attention according to increasing of 1-2 person households in the 1990s. The purpose of this study is to analyze the meaning of the terms about one-room dwelling written in the Korean dictionaries and the dictionaries of architecture terms. For this purpose, the first study was divided into three periods. The second study investigated publishing of the Korean dictionaries and the dictionaries of architecture terms and analyzed meaning of the one-room dwelling written in the Korean dictionaries and the dictionaries of architecture terms. The result are summarized as follows. 1) 'Bang' and 'Sil', the smallest residence unit, have sense of the living space. 2) The terms written in dictionaries were five terms. It is Dankanbang, Dankan house, Ilsil house, One-room house, Ilsil dwelling. 3) Dankanbang and Dankan house meant a detached house and only a single room. 4) Ilsil house, One-room and Ilsil dwelling meant a multi-unit dwelling. Dwelling type combined unit space in a single room. 5) One-room and Ilsil dwelling focused on convenience and multipurpose. The result of this study is expected to provide useful information for small sized housing study.

Houses in Jeju city are divided into separated types and combination types of household affairs space. Other special types are separated-kitchen type. Separated household affairs space type is mostly built. Separated household affairs space type were sitting room + Gopang separate type and separate sitting room type. Combination household affairs space type made from sitting room, kitchen, Gopang and Chabang(Dinning room) put together as space differentiation, also into classes sitting room + kitchen + Gopang + Chabang type, sitting room + kitchen + Chabang type, sitting room + kitchen + Gopang, sitting room + kitchen type by combination household cares space type. Separated-kitchen type was one of the special type from separated-kitchen type of traditional housing, and type with continuous. Houses in Jeju city were 3 kan type and 4 kan type. 4kan type was mostly built. ㅡ shape is kept as plan shaped of straight shape, and roof shape is showed as ㅡ shape gathering roof. ㅡ shape + part projection type talls part projecting type as happened in Gopang, and Chabang. Roof is gathering roof, and when it is showed ㄱ shape by Gopang, Chabang, and kitchen are projected. ㅡ shape + total projection shape is one of the room become totally projected by Gopang and Chabang, can be happen with small room or kitchen, and roof as gathering roof shaped with ㅡ shape, ㄱ shape, ㄷ shape, unsystematic ㄹ shape, and various shapes.

Steady state turbulent airflow and unsteady characteristics of generation, transportation, and recovery behavior of contaminate particles in the simplified 2 dimensional Vertical Laminar Flow (VLF) type clean room was numerically simulated using the low Reynolds number k-over bar.epsilon- turbulent model. Characteristics of airflow in VLF type clean room are greatly affected by the recirculation zone around working surface. The recirculation zone must be considered at the time of clean room design because the recirculation zone whose area increases with increment of inlet velocity exerts bad influence upon the performance of clean room in terms of particle contamination. The location of maximum particle concentration changes from the location of particle source to the recirculation zone, while averaged particle concentration is reduced exponentially with time. Recovery time of clean room with spontaneous particle generation source is inversely proportional to inlet velocity. We introduce nondimensionalized recovery time through the dimensional analysis, which can indicates the general performance of clean room with design structure change. It was identified that .tau. is independent of inlet velocity and background concentration. Therefore .tau. can be the simple factor to compare the different structure of clean room in terms of dynamic response to contamination and becomes larger with better structure of clean room.

In this paper, the acoustic performance of a shipboard large-sized room unit is studied. The room unit is a kind of rectangular absorptive chamber with a partition whose surface absorptive material with fabric skin is attached to. The room unit has one inlet and three outlet. At the inlet, a plane damper is installed to control the flow rate. The acoustic performance of a prototype room unit is measured using a HVAC mock-up. It is shown that its insertion loss is comparable with that of a commercially-used room unit but the developed room unit generates flow noise higher than the other one. The major source of flow noise is analyzed by NADS-R, the noise analysis program for room unit. Cone-shaped dampers are proposed to be used as the damper of a room unit to reduce flow noise. It is shown that the cone-shaped damper decrease flow noise remarkably.

The purpose of this study was to identify general characteristics of social lifespaces in Korean family houses and to investigate the changes in the physical aspects and room functions of social lifespaces from Yi-dynasty to the present. The documentary research method was used for this study. Total of 972 out of 1,109 floor plans were analyzed for this study. The major findings were that changes of social lifespaces from Yi-dynasty to the present have been affected by natural and socio-cultural environments. The changes in the physical aspects of social lifespaces have shown from one or two social lifespaces to various single-purpose social lifespaces such as living room, family room, drawing room, and study room. In the past, the cnetral social lifespaces, Anbang(women's quarter) was larger than the living room/Daechung(wooden floor) but the living room in the present has become a central social lifespaces and larger. The room function of Anbang has changed from multi-purpose space to private space. Living room/Daechung had used as a pathway rather than a social lifespaces in the past but the living room has played many fuctional roles of family social activities in the present. The kitchen has also begun to use as a social lifespace. This is a new symptom that kitchen and dining spaces will be included as a new social lifespaces.

The University students learn their major or a general education in lecture rooms. In these days, lecturer use frequently various multimedia in lecture room. Appropriate control lighting environment in lecture room should be essential and related in efficient studying. Daylighting on front-side of lecture room will cause glare and students are hard to read contents on white-board at their seat. Therefore, in order to preventing glare we simulated daylighting of lecture room with using computer software in this study. Results from simulation and analysis as follows: The first, if students' left-side is east-oriented in lecture room, best daylighting condition about glare in lecture room. The second, architectural designers can use simulation data of daylighting or simulate data in designing university buildings with lecture rooms. Finally, if reducing size of windows (narrow and deep daylight: more closing vertically, from up to down daylighting: more closing horizontally) we will be able to reduce energy from lecture room.

This study aims to examine and classify plane types of Hanok at Haengbok village, analyze changes, area distribution and space structures of space components and sort plane types and their characteristics. Plane types were divided into four; living room, kitchen, dining room, etc. These plane types were labelled as LK type, L+K type, L+DK type and LDK type. LK type and L+K type were mainly found at single-wing house and made of living room and kitchen centered space structure, but substantially they were designed to ensure guest room, room and living room. Therefore, hanok built at Haengbok village were designed to combine the functions of residential function and lodging. Plane type was preferred to be used for double functions of residence and lodging. On the other side, L+DK type and LDK type were mainly found in house with several wings and they were designed centering around living room for family space. In addition entrance was placed to simplify entry from the outside and each room and guest room were arranged to be accessed from living room. It means that the functions of house focused on residence rather than lodging and all rooms had the structure to be used as residential space in case of emergency.

Visible light communication (VLC) is considered to be an attractive scheme to realize the broadband wireless communication for an indoor environment. We present a room division multiplexing (RDM) mechanism for an indoor multi-room VLC network, which utilizes the spatial position of the LED lamp in different rooms as a novel dimension of network resource for multiplexing, and thus the network capacity is increased. In such a network, the service interruption caused by user cross-room movement is an important problem, and we propose a double-area-positioning based cross-room switch solution. An experimental platform demonstrates the RDM-deployed VLC network, and validates the performance of the presented switch mechanism.
