This study intends to find out the desirable teacher's image and to investigate the ideal appearance of the female teacher. The subjects were gathered into 403 high school girls, and convenience sampling was done regarding the number of schools classified by districts and regional characteristics of school. And for analysis of data frequency, percentage, mean, cronbach'$\alpha$ , $x^{2}-test$, 1-test, F-test, Duncan's Multiple Range Test, Factor-Analysis, were conducted. The results are as follows; 1. The subjects Preferred the understanding teacher to the intellectual teacher. 2. There were significant differences in satisfaction with the teacher's role-performance according to the school, grade of the subjects. 3. There were significant differences in reaction to the appearance of the female teacher according to the school, grade of the subjects. 4. There were significant differences in the ideal appearance of the female teacher according to the residence, school, grade of the subjects.

본 연구에서는 Duncan과 Johnson의 사각 벌지에 관한 이론식을 재료의 성질 및 파괴 특성을 결정하는데 유용한 방법인 타원벌지에 응용하여 고찰 검토하였다. 또 실험에는 각 점에서 변형도를 광격자법(photo grid method)에 의해서 측정했다. 그리고 극점의 곡률반경을 모아레 측정법으로 타원벌지에 처음 적용하여 구해서 이를 이론치와 서로 비교 함으로서 실험적인 측정법의 유용성을 밝혔다.

The purpose of this study was to investigate the goal and strategy differences in the Social Problem Solving (SPS) according to ages and interaction targets of children. The subjects were 48 children between the ages of 3, 4 and 5 years. Their SPS behavior was observed as it occurred naturally in free play interactions. The data were analysed by one-way ANOVA, Duncan's multiple range, repeated measures, and t-test. The results showed that there were significant goal and strategy differences in SPS behavior according to age and interaction targets of children.

This study explored a terminal values of home economics students at Chonnam national university in Korea. And the terminal values of them were compared with those of USA and Japan. Through this, it make to explain the similarities and differences in terminal values among 3 nations. 175 students were adapted as data in Korea. Data of USA and Japan were obtained from Holyoak, Sawai, and Rauniyar(1993). The data were analyzed by frequency, percentage, means, one-way ANOVA, Duncan-test. The results showed significant similarities and differences in terminal values among 3 groups.

Variations in the wood quality were analyzed to utilize Korean pine (Pinus koraiensis S. et Z.) efficiently and to develop suitable use, depending on the stem location. Variations in the tracheid length and width, microfibril angle, compression strength were measured at the heights of 0.3, 1.3, 2.3, and 5.3m in the longitudinal direction of the 20m pine and they were analyzed by Duncan`s multiple range test. Variations in the tracheid length, width and compression strength did not show significant difference, whereas those in the microfibril angle showed significant difference. However, the microfibril angle did not vary with the height of trees, showing inconsistent pattern in change.

Purpose: In this study, we evaluated the bond-strength between a few metal ceramic-alloys and veneered-porcelain and found if the bond strength of metal-ceramic alloy with lower gold content than the presently used gold alloy was high enough. Materials and methods: For this study, after plasticizing porcelain only for gold alloy, metal specimen was fabricated using Ni-Cr alloy and gold alloy with different gold content. Three point flexural test were performed to measure their bond-strength. Results: The bonding strength of Group 1 to porcelain was $40.62{\pm}3.32$ MPa, which was the highest (P<.05). In sequence of decreasing value, Group 2 (75%) was $37.47{\pm}1.57$ MPa, Group 3 (52%) $35.85{\pm}1.48$ MPa, Group 4 (51.5%) $35.04{\pm}1.34$ MPa, Group 5 (32%) $33.17{\pm}1.62$ MPa, Group 6 (10%) $30.75{\pm}1.21$ MPa. Bonding strength of Group 3 and Group 4 to porcelain did not show statistically significant difference with comparison to that of Group 5 (Duncan's test, P>.05), while there was a significant difference between that of Group 2, Group 3 and Group 4 and that of Group 6 (Duncan's test, P<.05). The bonding strength between gold alloy and porcelain increased according to the content of gold. In all experimental groups showed higher value than 25 MPa, which is the least value recommended by ISO 9693. Conclusion: In all groups, bonding strength was higher than 25 MPa, which is the least value of ISO9693. Therefore, it is considered that metal gold alloy with low gold content is clinically usable.

The purpose of this research was to analyze the relationship between the ease of crotch depth and the mobility of leg movement. Ten Korean men were participated as subjects and 0. 3, 6cm of crotch ease were inserted for test clothes. To analyze objectively, range-of-motion of four selected movements was measured by Leighton flexometer and goniometer. Also. wearer acceptability rating was measured for subjectively investigation. Anova and Duncan's range tests were used for statistical analysis. According to the results, 3cm of crotch ease was most comfortable. The mobility of test clothes with 3cm crotch ease was improved largely in every test movement(16.2% and 16.6% in segittal plane, and 6.1% and 6.2% in frontal motion).

The purpose of this study was to investigate some influencing variables related to the management behavior on environmental preservation of housewives in Pusan. The subject of this study were 411 housewives and interviewed with a questionnaire. The data was analyzed by SPSS/PC＋ Program for the frequency, mean, standard deviation, Cronbach's$\alpha$, t-test, F-test, Duncan's multiple range test and regression. The major result of this study were as follows : 1. The level of Environmental Management Knowledge was relatively high. The perceived level of environmental pollution was relatively high. The score of perception on water pollution was the highest. The level of management behavior on environmental preservation was relativity low. The score of management behavior on food pollution was the highest. 2. Frequencies of management behavior on environmental preservation differ according to age, education, relegion, and mass - media. 3. The influenced level of perception on air pollution was the highest among the other variables.

The purpose of this study is to investigate some influencing factors related to the perception and the management behavior on the environmental pollution of the housewives in the metropolis. small city and Kun. This study is also to provide some knowledge and information on the environmental preservation. 2300 questionaires were distributed to the housewives from the end of April to the end of May in 1994. The 1850 quentionaires were obtained and the 1490 data were analyzed by frequency, percentage, mean, t-test, F-test, Duncan's prohoc test, stepwise multiple regression, path analysis and pearson's correlation. The most hypotheses of this study were accepted. Based on the findings of this study, the degree of concerns on the environmental provlems, the enviromental education, the einvironmental articles and the paticipation of the environmental events were the most important factors on the knowledge of the environmental preservation and the perception of the environmental pollution. And these factors were exerted important effects on the management behavior on the environmental preservation.
