This study shows how the water space outside the housing impacts the indoor thermal environment. CFD simulation was used for this experiment to analyze the interior environment focusing on the effect of temperature control and the thermal comfort. A shape of perfect square, which creates the very basic space formation, was used and the simulation was processed looking at the size, distance, and the location of the water space. The results of the experiment are as follows. Firstly, introducing a water space with the same floor area size of the simulation model decreased the indoor temperature by 1 Celsius (3.72%). It was determined the interior environment was considered as a comfort zone when the water space was greater than 70% of the floor area. Secondly, there was not much influence to the level of thermal comfort of the interior environment when the distance to the water space from the housing was greater than 2 meters. Lastly, interpreting the location of water space, the effect of controlling the total areas' temperature was the greatest following with the surrounding of the formation. There barely was any change to the temperature considering the side and the rear of the area.

Apartment houses, the representative type of urban housing, are becoming an important element in Korea urban landscape. In this regard, this study aims to consider landscape in view of city residents reflecting human's visual perceptual characteristic, and in line with this, the urban landscape of apartment houses viewed from the urban center main intersections has been embodied according to the physical components of the intersections, which was followed by preference survey of the city residents, and then based on this, the visual-perceptual characteristics were examined. The findings are as follows: 1. The findings gained from the average of the landscape types indicate that the city residents are more satisfied when the shielding by surrounding buildings is minimized, view securing is relatively good, the whole complex is clearly observed because of its proximity to the visual point, and the view of the complex is well recognized from the focus point. 2. The examination concerning the preferred factors positively evaluated in terms of architectural planning shows that when the complex view is changeable sophisticated, makes the residents feel comfortable with its stable, open plan, and it's in harmony with surroundings, such housing attracts the city residents. 3. In terms of architectural planning factors, it turned out that the complex is more preferred when the visibility of the complex and the scale of surrounding green space are in good condition, and such elements of the complex as the sky line, the overall shape, the elevation, variation of the shape and height are harmonious with one another.

In the design guideline about the existing elderly housing, the equipment related to bathroom are the most important in the secure and functional aspect. On the other hand, the present elderly housing is being designed according to foreign design guideline or common housing form instead of reflecting living and physical qualities of the Korean elderly. Therefore, in this study based on the guideline of the existing literature, we made Mockup furnished with the equipments of bathroom and conducted an experiment in finding proper position and height for Korean elderly enough to use the bathroom conveniently and independently. The equipments of bathroom consist of different height wash bowls, toilet stools, grab bars, and a bathtub. As a result, suitable height of wash bowl is 760 mm $\pm{\alpha}$. We can realized that elderly feel comfortable to grab perpendicular bars of toilet stools more than horizontal ones. So it is necessary for elderly to grip perpendicular of grab bars added to prevention slipping and made shape easy to hold. Most of elderly told us that 500 mm of the bathtub setting is suitable. But many other people feel high. So height of the bathtub must be established lower than 500 mm for safety in the bathroom and for convenience.

In recent years, contamination of drinking water sources has emerged as a serious social problem, such as a large number of impurities in tap water or groundwater or the supply of suitable water due to rust of pipes. Although the government and public institutions are implementing various measures to protect water sources, they cannot improve water quality in a short period of time because of the enormous cost involved. Therefore, in recent years, preference has been given to a device that converts tap water, which is hard water, into soft water by installing a separate water softener at the faucet from which tap water is discharged. However, the existing filtration device has a problem that filtration performance is gradually lowered when impurities accumulate in the filter, requiring continuous filter replacement. In this study, the optimal design of the filter housing was performed to develop a water softener that can be washed when impurities accumulate on the filter inside the water softener connected to the faucet. For optimal design of the filter housing, fluid and fluid-structural interaction analysis were performed on the design pressure to determine the shape and thickness of the housing, and design review was performed through prototype.

Living room in modern housing accepts social behavior of modem family realized diversified life and the core of the housing space. So living room in the housing space is composed of many various components, handled very carefully in a color plan. This study is purposed on proposing basic data for color planing of the living room in an apartment, especially a sold housing accommodating the social change. As a result of understanding the color image of a apartment living room for the last 5 years, phenomenon of using natural color which makes people feel comfortable is common with durability. Also the image of space composition which usually called in modern, classic and dandy is appeared with various coloration easily in a medium-large or large living room, So these show the various demand of high-level or medium-level inhabitants. For an actual proof, basic data for research about the color image of a apartment living room in korea have to be accumulated constantly. After that the research which can take concrete shape and visualize the change of the color image of korean apartment living room will revitalize.

Building components have been deteriorated by various factors such as location, a building type, a surrounding environment and so on. In addition, each component has a peculiar characteristics, compared with other components in properties of matter an used part. Building components would be required to maintain its function and performance to provide the resident with a decent living condition. It is important to decide the repair time, scope and a required cost in repair plan, considering the each component's characteristics. In this parer, it aimed at providing the economic repair pattern to analyze the relation of the time-elapse and the cumulative repair cost in the apartment housing using 3rd quadratic function. Results of the study are as follows: First, the shape of the function for the economic repair is classified into two type. One is the continuous increase type of the cumulative cost which properly means the iterative repair type after built. The other is that the function has the maximum state at a point which means one-repair after its repair would be delayed to a scheduled time. Second, the iterative repair pattern would include window, roof proof, lighting and water supply pipe. The other repair pattern would include the paintings, heating pipe and sign board.

The purpose of this research is particle shape evaluation of aggregate using Digital Image Process(DIP). DIP is very useful to measure the roughness and particle shape of aggregates. Couple of aggregates, like standard sand, two different crushed stones, and two different marine aggregates, have been employed. Shape factors of two different marine aggregates are ranged 0.35 to 0.54. Crushed stone I is 0.74 which is highly flat, but standard sand is elongated shape. Especially, two marine aggregate showed a big difference of width and length which meaned a long shape. There is any significant difference of elongation ratio and flatness for each aggregate with different measuring system, like direct measurement of vernier calipers and DIP method. Shape conversion coefficient and equivalent diameter for changing 2D image to 3D image by the Digital Image Process(DIP) have been suggested and modified particle size distribution curve has been showed. The measured flatness ratios of each aggregate were 0.30, 0.36, 0.47 and 0.83, respectively. Also, the conversion shape coefficients of each aggregate were determinded as 0.77, 0.78, 0.84 and 0.92. The size of aggregate has been modified by multiplying the shape conversion coefficient and the aggregate size from DIP. The modified gradation curve with modified volume and weight of aggregate has been suggested. Within the limited test results, DIP is one of useful to get the particle shape of aggregate with limitation of measuring errors and to apply the particle distribution curve.

The actural condition of rural house polts, houses and their attached facilities was surveyed in CHUNGCHEONGBUK-DO in order to find out existing residential problems. From the data collected, general influencing factors, housing/residential environmental qualities, and farmer's opinion on them were analyzed or obtained as the basic design criteria for future projects. The structural shape of rural housing should be developed on the basis of our traditional one. The materials of wall should be made from soil sourced one. Kitchin room and rest room should be improved in view of the Western style. Residential space should be harmonized our traditional one(reception of a guest preferred) with westernized living space(nuclear family life preferred). The plane planning of 'ㄷ' type would be generally preferred in the block planning of rural housing and attached facilities. Livestock pens and compost houses would be seperated from, while storehouses would be coexisted with a living space.
