The purposes of this study are to understand residents' needs in regard to living space and to suggest how to provide layout options for the infill, based on their needs, so that the residents can change their living space to suit their own need. This study analyzed residents' needs in terms of living spaces through literature reviews on apartment remodeling and related previous studies. The results are as follows: First, the residents remodeled the various infill, and remodeling works are then classified into five infill groups according to the flexible features: 1) structural elements, such as flooring, ceilings, interior walls, and windows/doors; 2) equipment elements, such as lighting and electricity, electrical wiring, heating arrangements, and water supply & drainage systems: 3) finishing material elements, such as finishing materials for floors, walls, and ceilings, skirting boards, moldings, and art walls; 4) furniture elements, such as built-in wardrobes, storage closets, and kitchen cabinets; and 5) bathroom facility elements such as faucets and sinks. Second, based on the remodeling features, four ways to provide options can be suggested. 1) options are provided for each room; 2) options are provided in connection with structural elements; 3) options are provided for each finishing material element; and 4) options are provided with the combinations of different bathroom facilities.

Indoor air quality is the dominant contributor to total personal exposure because most people spend a majority of their time indoors. Especially exposure to indoor air can potentially pose a greater threat than exposure to ambient air when indoor environments have sources of contaminants. In this study, volatile organic compounds (VOCs) and formaldehyde (HCHO) within newly constructed apartment have been determined in 27 houses of apartment in Seoul from December 2004 to March 2005. The measured indoor air pollutants were HCHO, volatile organic compounds including benzene, toluene, styrene, xylene, ethylbenzene and sampled on the standard method of Ministry of Environment in Korea. The indoor levels for benzene, xylene, toluene, ethylbenzene, styrene, and HCHO have significant increase trend after 5 hours closing of windows and doors. Levels of measured air pollutants concentrations between living rooms and bedrooms have not shown significant difference. Spearman correlation coefficient among the measured air pollutants ranged from 0.303 to 0.946, indicating similar source in building materials.

Hoojo-dang is the Beol-dang of Gwangsan Kim's family in Gunja-ri, Yeaan This study aims to reconstruct the architectural drawings of the building through actual measurement, and by investigating documentary records of Kim's family, to trace and infer when the building was originally constructed. In doing this, it enables to identify and describe the architectural types and characteristics. The results are as follows, 1) Hoojo-dang was established in 1567 by Kim Bu-pil(1516-1577). From the beginning, Hoojo-dang, Byeol-myo(family shrine) and Ju-sa(shrine kitchen) were situated in the separate area from An-chae(main building). Later the Ik-rang(additional transept part) of Hoojo-dang was added to its main body as a room for entertainment. 2) The types of floor plan and windows of Hoojo-dang are similar to those of the lecture halls of Dosan-seowon, Sosu-seowon and Yeaan-hyangyo nearby. The main reason for the similarity of floor plan and window types in those buildings is that the students of the great Korean Confucian, Lee Hwang in 16th, managed and controlled those constructions. 3) The separate area composed of Hoojo-dang, Byeol-myo and Ju-sa was mainly designed for satisfying Confucian ceremonial principles. In addition, there are lifting doors designed for elevating the spatial flexibility.

Imcheong-gak[臨淸閣] was a familial residence constructed in the early half of the Joseon dynasty period. It was partially destroyed by a fire during the 1590s war[壬辰倭亂] with the Japanese, and another fire that was caused between 1631 and 1634. The inner chamber[An-chae] and the Sarang section[Sarang-chae] today is the result of a partial reconstruction that took place back in 1626 and again around 1634. The residence also went through some changes because the new Ondol[溫突] heating system had to be applied to the structure. Based upon sections that remain in their original forms, we can presume that the Imcheong-gak residence originally had an inner chamber which was composed of the following elements: A main structure which was built upon a foundation featuring a Matbae[맞배] roof, two "Ik'rang[翼廊, flank]" sections on the East and West sides of the inner chamber, and a "Haeng'rang[行廊, passage]" structure on the opposite side of the main structure. Unlike the main structure, other portions of the inner chamber were all built directly upon the ground, and showed multiple stories, with Matbae roofs of their own. We can also assume that the Sarang section in the south would have been a pre-Ondol[溫突] bedroom, with a Board platform[板房] and a Gomi-ceiling[Gomi-banza] fashion.

Building become higher. larger and more complex than ever before, showing abrupt changes in building structures. forms and mechanical systems. Likewise hazads of fire and the scale of fire losses become more and more greater. Therefore. considerations for fire safety take up great portion of the building design process. In this study, problems of high-rise building fires and basic directions for fire safety of high-rise building design were studied through the statistical analysis of 138 fire cases. The results of this study are summarized as follows : ·Most of the fires in high-rise building occur on the low floors and the fire frequencies are very low on the upper floors. Fire casualties are liable to be more on the upper floors than on tile floor of fire origin. ·The important causes of evacuation failures were analyzed as being late in escape and lack of stairwell enclosures. ·The main cause of vertical fire spread is lack of stairwell enclosures. However, the fire spreads mainly through the enterior windows in apartment houses. The combustible materials in buildings act on as the major factors of horizontal fire spread and the improper fire doors play role of another the critical causes. ·The basic directions for fire safety of high-rise building design put much stress firstly on the compartmentation of the buildings effectively performing the provision of safe escape routes and the safe refuse places in buildings.

The objective of this study was to identify the design characteristics of space components observed in Malaysian hotel lobbies. For this study, we conducted a case study on the facades and indoor space components of 15 hotel lobbies in Langkawi and Penang, and drew conclusions as follows. First, designs found in the facades and indoor space components of Malaysian hotel lobbies reflected all of traditional and colonial styles, religious styles including Islamic, and contemporary styles. Second, traditional designs showed rather the modernization of traditions than the preservation of traditions. Particularly in ceilings, walls and windows/doors, conservative or progressive modemization was observed frequently. Third, contemporary designs were mostly formative modernization, and materials and colors still adhered to traditions and nature. Fourth, in applied furniture, traditional wood sculptures were mixed or traditional material rattarn(stems of climbing palms) was utilized actively. Fourth, a large number of designs symbolized the Malaysian first religion Islam. Summing up these results, the common point of designs observed in the facades and indoor space components of Malaysian hotel lobbies was that they were transformed into Malaysian style regardless of whether they were traditional or colonial.

Infiltration characteristics of airborne particulate matter had been investigated in real-life for about 90 days over 2 years in a Korean apartment building where a 3-person household had lived and the exclusive private area was 84.9 ㎡. Airtightness was measured by fan depressurization, and the ACH₅₀ was 2.41 times per hour. In and outdoor particle concentrations were measured by optical particle counters. Infiltration factors and filtration efficiencies of the house, which reflect the removal of outdoor particles penetrating building envelope and the deposition inside a building, were obtained from data screened based on an empirical evaluation process. Infiltration factor of fine particles showed a range from about 42% at 0.4 m/s of wind speed to 72% at 4.2 m/s of wind speed with closed windows and doors. Filtration efficiency was like a MERV 13 grade filter with an open window outside at a balcony at low outdoor wind speed under 1 m/s. The grade decreased to MERV 11 by opening another outside window at the other balcony. Filtration efficiencies decreased as much as 29% in average at a range of 0.3~2.5 ㎛.

It was attempted to develop an auto part by over molding injection mold that produces precision products in high productivity with use of an eco-friendly TPE substitute material for NBR. NBR is currently used in motor gear cover, one of the key parts in motor module for auto doors. Gear cover is composed of plastics and rubber mostly today, which requires a two (2) step process for production using two presses of different types. A hot press is used at this time for forming the rubber, which has drawback of requiring a rather long forming time of 400 seconds for one forming process. Even though this difficulty is overcome by reducing production time through employment of multi-cavity molds, time for forming process must be shortened for improvement of the productivity eventually, and the existing method of insert injection for products that have been formed with plastic material must be outgrown. In this point of view, over molding injection using TPE has a big advantage. Forming time is shortened to 54 seconds, and working the two (2) processes in series by one (1) press could solve the durability problem caused by deflection of the plastics, not to mention shortening the process time. Enhancement of productivity by almost 80% and improvement in the accuracy of the product could thus be achieved.
