The purpose of this study was to provide the information for the development of gender-equality oriented content of Technology Home Economics subject. For this purpose, a total of 404 male and female middle high school students in Chuncheon city were sampled and asked to estimate the degree of practical use and preference for the 47 units of Technology Home Economics subject. Results were summarized as following : 1. The 47 units were classified into 4 groups on the basis of similarity in the degree of practical use and preference: 23 units estimated as 'better than average' by male and female students were classified into group 1; 4 units estimated as 'better than average' by female students but as 'less than average' by male students were classified into group 2; 10 units estimated as 'less than average' by male and female students were classified into group. 3; 10 units estimated as 'far less than average' by male and female students were classified into group 4. Most of the units in Home Economics area were classified Into group 1 or 2, but most of the units in Technology area were classified into group 3 or 4. 2. Gender difference was confirmed between male and female students' estimation of the degree of practical use and preference for the 47 units. In about three-quaters of the units in Home Economics area, female students' estimation of the degree of practical use and preference was higher than male students' estimation. In about half of the units in Technology area, male students' estimation of the degree of practical use and preference was higher than female students' estimation. However, possibility was detected in several units of Technology Home Economics subject that gender difference could be decreased.

The purpose of this study was to investigate multiple body-image and clothing-benefit sought according to body-cathexis. The questionnaire was administered to 458 female college students in Daegu and Kyungpook. The results were obtained as follows. Most respondents were dissatisfied with their body, especially with lower parts and weight. Among three factors of multiple body-image, degree of appearance-conscious was high, but degree of weight control and physical attractiveness were evaluated low. According to body-cathexis, differences were found in degree of weight control and physical attractiveness between groups. Respondents sought practical use of one's clothing most and comfort, figure flaws compensation, in turn. According to body-cathexis, differences were found in 4 factors of clothing-benefit sought, those were figure flaws compensation, sex appeal, individuality, practical use between groups. Between the factors of multiple body-image and the factors of clothing-benefit sought, positive or negative correlations were found, so it indicated that one's body-image was effected on clothing-benefit sought.

The purpose of this research is to examine the images and interest degree and purchase intension of consumer and images according to demographic characteristics for Hanji clothing products. 207 subjects evaluated images for Hanji clothing and attitudes and behaviors of consumer were analysed. For statistical analysis, frequency analysis, factor analysis, mean, pearson correlation coefficients, regression, crosstabs and ANOVA were used. The results were as follows: Image factors of Hanji clothing products were 'luxurious', 'practical', 'wellbeing', and 'traditional'. differences of according to the age and occupation were showed at 'practical', 'wellbeing', and 'traditional' image. Hanji clothing products having highest consumer interest degree and purchase intention were shirts, scarf and handkerchief and Hanji clothing products having highest experience of use was socks. interest degree, experience of use, and purchase intention for Hanji clothing products were increased at high age, office worker. For consideration of Hanji clothing products according to demographics variables, age of 20's-30's and students considered design and functionality and age over 40's and office workers regarded price and quality as important consideration.

This study examined the effect of home informatization on housewives' home management ability. The questionnaires of 338 housewives who have at least one child were analyzed. LISREL 8.5 version program was used to examine the obtained data. As a result, degree of practical usage of information had positive effect on the home management ability directly. Internet use and information communicative machine usage also had affected the home management ability indirectly.

이 연구는 GIS를 이용하여 지형의 개석도를 측정하고 그 결과를 지도화 하여, 연구지역의 개석도와 토지이용과의 관계를 분석한 것이다. 지형의 개석도 분석에 GIS의 활용하면 전통적인 수작업에 비하여 시간과 노력이 획기적으로 절약되고 개석도 분석에 적용되는 변수를 다양화 할 수 있으며, 그 결과물을 이용한 2차적인 연구도 가능하다. 이 연구도 이러한 배경에서 출발하여 GIS를 활용한 개석도 분석 방법을 모색하고, 개석도의 분석 결과와 토지이용도를 비교 분석하여, 개석도의 분석 결과에 대한 적극적인 활용을 시도하였다. 연구지역인 강릉 남대천 유역권의 개석도와 농업적 토지이용 사이의 관계 분석 결과, 농업적 토지이용 대부분 지형의 개석이 많이 진행된 지역에 분포한다. 특히, 농업적 토지이용 중 논과 밭으로 이용되는 토지가 개석도와 더 높은 상관도를 보였다. 지역별로 개석도와 농업적 토지이용간의 상관관계를 비교하였을 때 토지이용이 집약적으로 이루어지는 동지역이 읍면지역에 비하여 상관성이 낮게 나타났다.

Regulated Deficit Irrigation (RDI) is one of the most important measures for the water-saving and high yield of crops. RDI is based on the crop and water relations. The theories of RDI were analyzed using the experiment data in Shaanxi and Gansu Province. There are several problems of RDI in practical use, which include; the uncertainty of crop-water relations, the proper growth stages and water deficit degree of RDI applied, and the requirements of RDI to irrigation system and irrigation techniques.

In this paper, a simple practical method is introduced in which a simple weight measurement of concrete and finite element numerical analysis are used to determine the moisture transfer coefficient of concrete with a satisfactory accuracy. Six concrete mixtures with different water-to-cementitious material (w/cm) ratios and two pozzolanic materials including silica fume and zeolite were examined to validate the proposed method. The comparison between the distribution of the moisture content obtained from the model and the one from the experimental data during both the wetting and drying process properly validated the performance of the method.With the proposed method, it was also shown that the concrete moisture transfer coefficient considerably depends on the pore water saturation degree. The use of pozzolanic materials and also lowering w/cm ratio increased the moisture transfer coefficient during the initial sorption, and then, it significantly decreased with an increase in the water saturation degree.

In practical control systems, the capacity of actuators is limited and this degrades the system performances and it is often a source of instability. To use full capacity of actuators, we adopt the gain scheduled control permitting the over saturation in controls. The basic idea of gain scheduled control is to use a higher gain control when the state variables are smaller and a lower gain control when the state variables are larger. First, we derive a constant H control and a reachable set while satisfying the degree of over saturation. Next, we divide this set into nested subsets and find $H_{\infty}$ controls at rack subsets while satisfying the degree of over saturation. Finally, the control gain is applied according to the status of states. Note that all procedures are done by solving linear matrix inequalities(LMI). Finally, we show the validity and applicability of our proposed control using the simulations of a six-story building subjected to the earthquake excitation.

This paper is to find and to suggest alternative ways of description on function chapters in the middle school mathematics so that the descriptions be more closely related to daily life. The research has two phases: one for belief on the usefulness, the other for cognitive ability to solve the practical problems. Results are as following. 1. Most descriptions of corresponding chapters have emphases on the usefulness of functions so as to enhance beliefs on the use of functions. 2. Most practical functions contain expressions of large constant term and large coefficients in magnitude while those are not in the descriptions of tektbooks, especially in case of using ruled papers. 3. For quadratic functions, most students do not detect the degree of the function from the data presented by pairs of values of x and y. And those are not dealt with in most of textbooks, which are given in the MIC textbook.
