This study conducts a questionnaire with undergraduate students in the Dept. of Architecture who will lead the architectural field in future, examines environment and perception of CAD in their home and universities and aims at supplying the data required for setting CAD educational index and building its use environment, and it could obtain the following results. Individual CAD environment of undergraduate students in the Dept. of Architecture reach a considerable level in hardware part, but they don't have the same level in software part as the hardware and use illegal copy programs. It is shown that they spend their time in using CAD for five to eight hours a week and its main purposes are to perform a project related to architectural design or make report requiring drawing. Major places using CAD are CAD room in university or public PC room equipped with CAD compared to their own houses and most of them have a negative recognition of the convenience of its use. Their satisfaction with CAD use is considerably high and when they submitted their assignments of architectural design project by means of CAD, they had a positive evaluation from their professors and they have such hopes that 'Korean Support Strengthening', 'lowering price through version supply for students' and 'diversification of design symbol' in CAD S/W, and especially, most of respondents have an intention to purchase the original goods when version only for students will be marketed in future. Accordingly, for a qualitative improvement of CAD environment for undergraduate students in the Dept. of Architecture, universities must be equipped with the various types of CAD S/W and Applications and students' opportunity to access them should be increased. In addition, a method which can enhance using convenience of CAD room and PC room is required and CAD related S/W developers must market the version for students which consider the reality of undergraduates in Korea properly with an appropriate price level in order to settle a sound S/W culture.

In order to control moving facilities on a remote place effectively, it are required to acquire a environment informations such as images where the moving facilities are placed. However, since there is no tools to acquire such informations to the central control system based on the non-networked sensor environments, it is difficult to control the moving facilities remotely. Therefore, we design and implement the Zigbee based image transmission system and communication protocol to control the moving target remotely. The wireless control utilizing the Zigbee protocol is that electrically consumption is more small than the Bluetooth and reliability of data transmission is better. The implemented Zigbee based control systems and communication protocol have the normal and replay function for a realtime control of the moving target under the server PC and the mobile FDA with the WiFi protocol. The functional operability and performance are analyzed by a designed prototype under the wireless home network environment.

The purpose of this study is to suggest how we can get over the difficulties of practical drill under experimentation concerning the units of making clothes in the curriculum of home economics. The import of this study was based on the results of the preceding studies the field of the making Korean clothes, from the standpoint of the teaching tools and teaching materials by the use of VTR, is one of the most insufficient. On the one hand, the teaching procedure here a VTR, running 34 minutes or so, was made up with the process of making Korean men’s slacks, and was led by the researcher’s own. The contents of the lesson are as follows： the shape of Korean clothes, the name of each part, the process of drawing, cutting and sewing, and the items of evaluation and arrangement. On the other hand, the two comparative groups were made to compare one with the other： One group was taught by help of VTR media, and the other by the model performance and explanation of the instructor’s own. All of the statistical data were analyzed in terms of SPSS/PC, and t-verification was made, to make difference between the two, after standard deviation was calculated according to the classified domains. The consequences of the test research are shown as below： 1. The difference of understanding was obviously made in considering that the group made a better score than the comparative one in understanding to process of making Korean clothes. 2. The difference of skill was highly made in considering that the group made a better score than the comparative one in the practical drill of making Korean clothes. 3. The difference of interests was evidentally made in considering that the group made a better score than the comparative one in the stage of making Koran clothes. Such means that the motivation and attitude of the learners was made stimulate by the Audio-Visual material than by the traditional cramming method. 4. The difference of frequency was fairly made in considering that the experimeatal group made a better score than the comparative one in the frequency of individual teaching. 5. The difference of the efficiency of time-consumption was clearly made in considering that the experimental group made a better score than the comparative one. As the results of the research above, the medium of VTR proved to more effective to the achievement of schoolwork and the strategies of teaching. Therefore, more use of VTR media will help the instructors with the difficulties of practical drill in the whole process of making Korean clothes； Widely use of VTR media in teaching will be surely more fruitfull to the unit of making Korean clothes than teaching by explanation.

This study is designed to identify the current condition of male students ostracized as the black ship (Wangtta in Korean) in middle schools and the effects of the Guardian Angle program on the decrease in Wangtta. 428 frist graders of two junior high schools were devided into two groups, a test group (n=195) and a control group (n=233). SPSS/PC+ program was used for analysis of the data, including frequency analysis, ANOVA and x(sup)2-test. The outcome of research can be summed up as the following 74.7% of the subjects thinks that there is Wangtta going on in there classes. Wangtta often comes to pass during the recesses (74.2%) and lunch times (51.6%). Those who are easily exposed to Wangtta are most likely to be both snobbish and pedantic. Those who lead Wangtta turn out to be good at fighting (56.4%) and dominant in the hegemony of the class depending on the way of ignoring or not playing with the victims(69.3%) In the case of bearing witness to Wangtta. 36.9% of the subjects try to overlook the case. Now let me take a look at the effect of the guardian angle program on the decrease in Wangtta. The program has a significant effect on the decrease (p<0.05) in the number and the phenomena of Wangtta perceived by students in both advance and post tests. The program makes a significant difference in the aspects of students’ behavior in relation to Wangtta in a desirable way (p<.01) Though the sociality index of the victims doesn’t show any significant difference statistically, it exerts a generally positive effect.

The main purpose of the research was to prove, in a practical sense, the relationship among perceived equity, role stress and life satisfaction of employed wives working in sales departments. The subjects were employed wives working in sales departments who have at least one child and a spouse, living in Seoul and the Metropolitan area. The final data analysis used 487 out of 668 questionnaires. Statistical analyses were carried out using SPSS/PC WIN which included frequencies, mean, percentages, Pearson's correlation, Cronbach's ${\alpha}$, factor analysis, multiple regression analysis. The findings of the study were as follows: 1) As their education level was low, the education level of their spouse was high, the communication level between couples was high, and the self-oriented perfectionism was low, their perceived emotional relationship was equal. As they were old, the communication level between couples was high, and the self-oriented perfectionism was low, their perceived position in sharing household chores was equal. On the other hand, as they were younger, the education level of their spouse was high, the reason for getting a job lay in supporting the family, and overtime hours worked, there was a higher level of role stress. 2) The influential variables which affect the life satisfaction, in order of importance, were communication level between couples, mother's role stress, age, non-financial reason of getting a job, and sharing household works. For relative contribution degree about life satisfaction, psychological variables among independent variables were revealed as the most influential ones. Thus, efficient communication between couples affected the life satisfaction to a great degree. Furthermore, the study proved that not only role stress variables but also perceived equity variables contributed to the life satisfaction.
