Recently, the housing problem has been recognized as a matter of housing supply with a certain environmental level and not simply a matter of handing as a quantitative problem, and the demand for pleasant residential environments and requirements for residential environments are increasing more and more. However, it is necessary to establish the directions for improvement of the residential environment according to the house type, as the requirements and levels of satisfaction differ. This study aimed to deduce the level of resident satisfaction with the residential environments according to house type, and determine the direction for improvement of the residential environment. To achieve this, the difference between the house types was analyzed through ANOVA analysis and T-Test, and the major factors on the improvement direction of the residential environment were derived through Action-grid analysis.

Wooden houses are classified into Traditional, Modern, Platform, Timber framing types. The most popular type is Platform framing which is come from foreign culture. The foreign and Korean tree structure tend to be incompatible with Korean culture and don't fit well with modern lifestyle. In this study, it will analyze the design characteristics of the traditional and modern wooden house to solve these problems. The design characteristics will be contributed to the development of wooden architecture which is suitable for Korean architectural style and lifestyle The research consists of space analysis, plane analysis, structural system analysis, roof type analysis, and aesthetic analysis. From the analytical results the design characteristics of traditional Hanok and modern wood structure, we propose the modular elements and the inner and outer shapes of the Korean - style wooden house.

A survey was conducted to examine the fatigue and the related factors in pregnancy. 426 pregnant women were recruited from antenatal clinic at 8 hospital from November 1, 1997 to January 1, 1998. Fatigue was measured by the Modification of the Fatigue Symptoms Checklist(MFSC) developed by the Industrial Fatigue Research Committee of the Japanese Association of Industrial health(Yoshitake, 1978). The MFSC consisted of 34 items with 4-point Likert scale. Minor discomfort during pregnancy was measured using a 14-item checklist with 4-point Likert scale. The data were analyzed by percentage, t-test, ANOVA and Pearson correlation. The major findings of study were as follows : 1. The average fatigue score during pregnacy was 63.02 and the average minor discomfort score was 26.92. 2. The fatigue score of nullipara was significantly lower than that of mutipara. There was a significant difference of fatigue score between pregnant women with conjugal family and those with extended family. The fatigue score during 1st trimester was the highest in comparison with that of 2nd and 3rd trimester of pregnancy. 3. The fatigue score of pregnant women who worked for house-keeping only was significantly lower than that of pregnant women who worked partially or did not work for house-keeping. 4. There were significant correlations among each type of measure of fatigue and discomfort. Fatigue was the most common symptom during pregnancy and related to type of family, house-keeping work, and parity. Nursing intervention such as self-car, relaxation, and nutrition would be developed to manage fatigue problem in pregnancy.

Mesoporous nickel intercalated aluminosilicate nanohybrid has been synthesized through a recombination reaction between the colloidal suspension of exfoliated montmorillonite nanosheets and aqueous nickel acetate solution. According to powder X-ray diffraction and field emission-scanning electron microscopic analyses, the intercalation of nickel species expands significantly the basal spacing of the host montmorillonite clay and the crystallites of the intercalation compound are assembled to form a house-of-card structure. $N_2$ adsorption-desorption isotherm measurements with BJH pore analyses clearly demonstrated that the porosity of the intercalate originates mainly from mesopores (diameter $\sim50\;\AA$) formed by the house-of-card type stacking of clay crystallites. From FT-IR and X-ray absorption spectroscopic analyses, it becomes certain that intercalated nickel ion is stabilized in an isolated $NiO_6$ octahedral unit. The present mesoporous intercalation compound is expected to be applicable as efficient catalysts or absorbents.

This study outlines the housing consciousness and needs of single woman household. In order to analyze housing consciousness of single woman household, surveys were conducted with the questionnaire composed of housing consciousness, housing needs, socio-demographic and housing characteristics of single woman household who lived in Seoul, and other near metropolitan area such as Gyeonggi and Incheon. The result of the study shows that single woman household put importance on safety, privacy, and comfort of their indoor housing environment. For single woman households convenience in transportation and facilities for leisure time were one of the important conscious factors. Housing consciousness of single woman household can be categorized into mainly three groups: (i) indifferent to overall housing consciousness except for convenient services such as front desk service at the lobby and maid house keeping services; (ii) privacy conscious group - this was the majority; (iii) relatively active housing consciousness group. Each type had different preference factors when selecting a house. That is, each showed difference preferences when considering types, sizes and services as well as motives for choosing a house.

It is important to increase the sound proof performance of building for reducing the influence of aircraft noise on the bais of actual survey of existed buildings. The purpose of this study is to propose the basic data for designing sound insulation of residential house. In this study, field measurement of aircraft noise Interior and outside noise level difference were carried out for 7 days in 2 residential houses. As the result, aircraft noise levels showed to be Leq $71.8{\sim}74.5$dB(A), WECPNL $82.2{\sim}83.4$ and indoor noise level were NC-55 ${\sim}63$ over acceptable NC-30 in 2 measured houses. Noise reduction effect showed to be $15.8{\sim}23.1$dB(A) in measured houses, and houses with double window were preferable to those with single window in sound proof performance. The outside sound pressure level for residential house was a little different according to the type of source. In measuring by using aircraft noise it was effected by angle and distance from measuring point, to aircraft, window area, and sound absorption of room, and so on.

The 181,000 DWT Bulk Carrier has a different deck house type, which is not typical for previous bulk carriers, to meet the new international rules for bulk carriers. This new deck house has much smaller transverse breadth than the hull's transverse breath, resulting in large levels of the transverse response of the deck house. In addition, the longitudinal response of the funnel showed rather a large magnitude of vibration, which are excited by the ship's main excitations such as the main engine H-moment and the propeller surface forte when the ship operates at the NCR and the MCR speeds In the ballast condition. To solve these issues, the global forced vibration analysis has been performed for the ship and the ship structure has been modified to reduce the vibration level by increasing the girder depth and adjusting the engine room tank arrangement.

The purpose of this study was to develop a computer operated automatic drip irrigation system for application in vinyl-house cultivation. The results can be summarized as follows: 1) The T-type ice compensation wire was used to measure the temperature. The voltage level measured up to 0.02 volt was used as input to an 8-bit A/D converter. 2) A specially devised tensiometer was used to content the watering system. When the needle of the pressure gauge reaches the lower threshold position it turns on the pumping system and turns off when it reaches higher threshold position. 3) In order to use the multiple gypsum blocks for one transducer, reed relays and a D/O board were used to make the sequential switching possible. 4) It was possible to automate the trickle irrigation system for the whole growth period of vinyl-house crops with the help of microcomputer. 5) In terms of furrow irrigation, the irrigation water consumption was the smallest, 2.8 times less than conventional method of surface trickle irrigation, 3.4 times less than subsurface trickle irrigation method. 6) In terms of productivity of cucumber, there was a drop in productivity when compared to furrow irrigation method, 7.2% for surface trickle irrigation, 27.4% for subsurface irrigation method.

Owing to the energitic studies of the leading shcolars, some paradigmatic theories on the history of Korean dwellings have been suggested. They constructed periodization of their own and defined characteristics of each period with very limited historical materials. However the new historical materials have been discovered in the neighboring academic fields, which require to review the existing theories. This study aims at restructuring periodization in the history of Korean dwellings during the age of The prehistory and The ancient Kingdomes. Through the study, the existing theories on the same period are revived and evaluated based on the new materials. I suggest a new theory on the periodization and the characteristics of each period: a. the paleolithic period(6,000,000 B.P.-10,000 B.P.) : natural shelter, the emergence of man-made dwellings b. the neolithic period(10,000 B.P.-1,000 B.C.) : construction of pit house c. the bronze period(1,000 B.C.- 300 B.C.) : construction of semi-pit house d. the early metalic period(300 B.C. - 300 AD.) : construction of house on the ground level development of the Ondol system e. the ancient kingdomes period(300 AD - 700 AD): classification of housing type
