In this project a preliminary experimental research work was done to apply mortars containing magnetite as fine aggregates unto floor finishing materials in order to make indoor environment eco-friendly and to have noiseproof control between floors. Crushed magnetites were substituted as sands in the mix design with a range of 0, 20, 40, 60, 100%. First far-infrared radiation tests to determine emissivity and emission power were done in accordance with the KICM test standard and an outstanding result was obtained. Density and compressive strength test results also showed that as the substitution increases, test values increase in a linear trend. However dry shrinkage test results revealed that as the substitution increases, shrinkage strain also increases. To clearly seek a solution about this problem, more experimental works should be done on oncoming experimental program.

This study investigated the present traditional Korean farmhouse based on a survey of 30 households from Oiam-Ri folk Village in Chung-Nam Province. This study was primarily concerned with the present housing; the size and plan of the house, lighting and heating, the finishing materials of anbang(the master's bedroom or ondol) and the kinds of fumiture. I was also interested in identifying the socio-demographic and physical variables that influenced the housing, both the ordinary farm households and the descendent of nobility households. Bibliographical studies, cultural approaches, field surveys with tape recordings, and questionnaires were used to collect the data. The results showed that the types of house plans were mixed from the southern region(one-line type) and middle region(courtyard type). The heating system and the fuel for the ondol anbang has changed entirely from wood burning system to oil boiler system. The finishing material of the anbang floor changed from traditional oil paper and straw mats to vinyl flooring. Traditional fumiture and small decor items are disappearing and are being replaced by modem items, but the descendents of the nobility household kept many traditional type of fumiture and small decor items.

Community facilities in apartment complex have been developed through residents' needs for housing environmental amenities and social trend for 'Well-being' combined with marketing competition among construction companies. But community facilities and fitness centers which are in the initial stage of development are not well fit with residents' needs because the designers plan the community facilities without considering on residents' life-style and preference. This study investigates the present status of fitness center, and surveys the residents' preference for the proposed fitness center design. The result includes that fitness center users in apartment complex want a convenient and comfortable resting spaces similar level with those in fitness center of mixed-use residential building. A resting space provides opportunity that community members meet each other as well as they can rest after exercise. The result also shows that the fitness center users prefer wood floor and wall as interior finishing materials in exercising space and resting space, which users think, gives more comfortable and splendid feeling.

This study was carried out to find the cases of change in the Anglican Church including its rectory in Onsuri, Gangwha island, which was built in Korean traditional architecture style. The materials used for the study were published books, old photos taken before the change, drawings, and field survey. The result are as followings. 1) Painting concealed natural wooden grain should be removed as well as carpet on the wooden floor. The way of ceiling finishing is to be restored as traditional way. 2) Refer to the rectory, it needs to be restored totally, since it has been changed many times through partial renovation. It lacks unification of design in entire elevation, windows and door. The practical spaces such as indoor flush toilet and boiler room are desirable not to be revealed or designed in harmony with other spaces. 3) Stript flooring in the rectory are to be restored to frame flooring, room finishing including vinyl flooring, vinyl wall paper and moulding along the cornice to the traditional paper finish. Lattice patterns of windows and doors are recommended to be restored according to the traditional design.

According to the statistical surveys and studies, insufficient maintenance in the use of existing buildings caused fire and collapse accidents. In this respect, I analyzed the data managed by the current building maintenance and inspection system to find out the actual state of safety management and proposed two significant results. First, regarding the state of the buildings, the safety management status of the small-sized ones, where 20 years or more passed after construction, is the worst and a priority improvement plan is required. Second, there are eight deeply concerning factors for the fire incidents and collapse accidents of buildings. In the order of high risk, these factors are structural strength (seismic design), exterior wall finishing material, basement floor, interior finishing materials, other evacuation facilities, corridors stairs entrances, rooftop, fire partition. We need to have more special designs and management plans regarding high-risk factors as a system to prevent accidents in the building.

Self-leveling material(SLM) is one of the floor finishing materials which make flat surface like as water level by itself in a short time. So it is possible to increase construction speed and enhance economical efficiency. In this study, author intended to develop SLM for the industrial warehouse and factory loading heavy weight machinery and vehicles. The demanded properties for this type of SLM are above 20mm of flow value and above 300kgf/cm2 of 28-days compressive strength. To possess demended strength and fluidity, SLM have to be composed of many types of binders and chemical additives. So it is difficult to decide suitable mixing proportion of composition materials. In this study, author investigated the weight percentage effect of main composition materials for high-strength self-leveling material, by experimental design such as tables of orthogonal arrays and simplex design, and by statistical analysis such as analysis of variance and analysis of response surface. Variables of experiments were ordinary portland cement(OPC), alumina cement(AC), anhydrous gypsum(AG), lime stone(LS) and sand, and properties of tests were fluidity of fresh state and strength of hardened state. Results of this study are showed that suitable mix proportions of binders for the high strength self-leveling materials are two groups. One is 78~85.5% OPC, 7.5~9.5% AC, 9~12.5% AG and the other is 72.5~78% OPC, 9~12.5% AC, 13~l5% AG.

The purpose of this study is to grasp the preference of colors in housing spaces by different type of personality and color preference by classifying dwellers various characteristics by MBTI to obtain basic informations for the color plan that satisfies their inner desire. The results of this study are as followed. Firstly, we could say about the color distribution of living spaces like that. The ceiling and general wall showed that N(white) systems and YR of bright tone was mostly distributed. The color of floor showed that the calm tone of YR was mostly distributed. Secondly, as for the favored colors of finishing material at each space, the biggest distribution of preference color was found as N(white) group(series) in case of ceilings. As for general walls, bright tone of N(white) group showed most in living rooms. In case of that of the floor, it showed the largest distribution of calm tone of YR. Point wall was preferred bright and brilliant in various kinds of color. Thirdly, as in favor of colors of closing materials, sensible types(S) are concentrated on common color groups, on the other hand, intuition types(N) prefer color groups of various kinds not only general preferred colors.

The purpose of this study was to determine the effect of a pleasantly designed interior inpro-spatial behavior. For pleasantly designed interior, the existing interior was remodeled through the change of finishing materials for major architectural elements such as wall, floor and ceiling, and changes of furniture and it's arrangement. Prospatial behavior was operationalized as seat arranging behavior and measured through the arranged condition and observable arranging behavior. Time-series design, one of quasi-experimental design was used. The data in this study were extracted from an existing field experimental research. One hundred forty four video tapes recorded during 6 months out of 2 years period ware used. In conclusion , the pro-spartial behavior change was a mid-term positive effect of pleasantly designed environment. In an environmental setting where pro-spatial behavior was most important, a certain time cycle to change the environment needs to be considered.
