We are studying on the home economics, particularly tools and machines used in household affairs. The object of this paper is to rationalize house cleaning method and to improve the used cleaning tools. We have made a social survey in Korea about the real situation of house cleaning as the first phase of this research. The contents are as follows: 1) The consciousness of housemakers for house cleaning. 2) The methods of house cleaning. 3) The used type of vacuum cleaner. 4) Merits and demerits of vacuum cleaner. 5) Troubles of vacuum cleaner etc. The results has been made in comparison with the same social survey in japan and a small scale different survey in The United States of America by auther in 1979. The results are as follow (in Korea). 1. The almost of housemakers are affirmative in charge of household affairs(95%). 2. In household affairs, only 9% of housemakers dislike cleaning work, but 40% of housemakers do not a cleaning work as a daily periodically. 3. In general household, they do a cleaning work with broom, duster and dust cloth, and then the cleaning work is faily backward in mechanization(The possession of vacuum is 19%). 4. The main dissatisfaction of vacuum cleaner is a noise, and also the difficulty of the cleaning in a corner of the room is shown in high percentage too.

The purpose of this study was the analysis of electric energy consumption with the case study of tower type apartment's opening of building surface. We analyze the relationship between tower type apartment's opening of building surface and using electric energy consumption. The results of this study are: 1) The highest energy consumption of electric energy was on August without any influence of opening types of building surface. 2) Also, the south-west sides consumption of August was 848 kWh on Type B(one side opening) and it was the highest usage. 3) A house if facing west used more electricity than facing east when its opening of building surface's datum level is facing south. However, the house of facing east used more power than west when its opening of building surface's datum level is facing north. 4) When opening of building surface is facing on north-west or north-east, the opening of building surface's side of west and east used more electric power than north-west or north-east sides.

This study attempts to explore the organization of domestic space in Belgium and then to compare them with those found in Korea. Data were collected by questionnaires mailed to 110 staff members, both academic an dadministrative, working at Vrije Universiteit Brussel in Belgium.The major findings of the study can be summarized as fllows: First, the most common pattern of Belgian LDK(living-room dining-room and kichen) layout is the LD type, which separates K from L and D by wall or door while linking L and D to each other. On the other hand, a large portions of Korean LDK layout is the DK type , which seperates L from D and H, but D and K are interconnected. As expected, the bigger the size of floor space, the more likely L-D-K type is to be, which places L, D, and f, separate each other. And the smaller the sire the more probable the DK type and/or the one room type would be, where L, D and K are merged into one room. Second, the enterance of domestic space in Belgium is normally found adjacent to public space. The Belgian entrance often forms a space independent from other parts of the house, or a space that leads directly to garage. These two patterns are rarely found in Korea. Third, Belgians tend to locate Kichen in the front of the house when they design apartment units, Whereas it is not the case in Korea where it is located in the rear.

The objective of this study is to develope ground heat exchanger using PHC file used to building foundation, and it's element technology. So we construct PHC ground heat exchanger in the apartment house's PHC foundation and evaluate it's performance. First, we study PHC file type, heat exchanger pipe, grouting materials, and present apartment house's foundation condition for PHC ground heat exchanger and design it's proto type. Second according to grouting materials, we estimate construction convenience, and it's performance. Construction convenience side, PB 22 A pipe and sand grouting with moisture was good for PHC ground heat exchanger elements. Experiment result is very superior. Thermal conductivity B, C type(sand, gravel) was respectively 32.4 W/m$^{\circ}C$, 36.5 W/m$^{\circ}C$, D(concrete) Type 27.8 W/m$^{\circ}C$, E(bentonite) Type 19.6 W/m$^{\circ}C$. Thermal interference for 4 day experiment period in 3.8 m was very small. So PHC file is good for using ground heat exchanger.

Today, we are living while interchanging with various countries in multilateral measures and residential culture have been changed while interchanging in the same manner. In order to become an internationally recognized residential environment designer in this environment, we must understand the housing viewpoint of residents in that country first. Therefore, this study is intended to obtain the useful materials for residential environment design of Korea and China by comparing the housing viewpoint between Chinese students studying in Korea and Korean students. A survey using questionnaire was conducted on 205 Korean students and 193 Chinese students (Chinese race) from Y University on a random sampling basis. The result of survey is as follows. First, as both Korean and Chinese university students have a similar tendency on previous house type, current house type, and desired house type, it can be understood that they are similar each other in the experience and preference of house type. Second, Korean and Chinese university students consider and as the most important functions of residence, but Chinese university students consider more functions of residence than Korean students. And, both Korean and Chinese students consider a living room as the most important space among housing spaces, but Chinese consider a private room more importantly than Korean. Third, Chinese university students have stronger desire to possess houses, and desire to purchase houses with larger and more rooms at earlier time than Korean university students. Fourth, when selecting the house, Chinese university students give a higher consideration in terms such as , , , , and than Korean university students. Fifth, satisfaction level of Korean students on current houses was average as a whole, and most Chinese students were generally satisfied with their houses. Sixth, as both of Korean and Chinese university students have higher level of consideration in the items such as safety>, , , , , , , , , , and compared to the level of satisfaction, thoughtful consideration should be given to those items in housing planning.

The purpose of this study was to small house plans according to the preferred type of emotional design. The human emotions was a major factor for small houses plan's needs. In this study is direction of the basic plan for the small houses of the spatial planning and services and the needs of community facilities. Preferred types of emotional design was identify the propensity of consume, adjectives, colors and forms. For this study, survey methods were used for data collection. The effective numbers of survey questionnaire was 183, and the survey analysis has been made by using of SPSS win 18.0. The major findings were as followings: 1) Preferred types of emotional design were "Eco-Classic oriented group", "Unspecified commonness group", "Creative design oriented group" classified. 2) "Eco-Classic oriented group" wanted Eco-system and the community space. "Unspecified commonness group" wanted Simple and universal style. "Creative design oriented group" wanted flexible styles and various items. Therefore, depending on need group is the main target-specific as well as flat planning and interior style facilities and the provision of services to be competitive in the small house could indicate. These results can provide improvement guidelines for the small house plans.
