본 연구의 목적은 국내 사회복지악계의 사회적 지지에 관한 지난 10여년간의 연구를 정리하고 집중적인 내용분석을 아는데 있다. 분석대상논문은 1990년대 이후부터 2002년까지 노인관련 학술지와 사회복지학술지에 게재된 사회적 지지에 관한 연구들이며, 총 30여편이었다. 연구결과는 사회적지지에 관한 연구들은 90년 중반부터 활발히 연구되었으며, 사회적 지지의 연구대상은 노인이 많았다. 사회적지지에 대한 개념 측정은 기능적 특성을 측정한 연구가 많았고, 측정도구의 사용이 불분명해서 측정도구의 타당성 문제와 표준화된 척도의 필요성이 제기되었고, 효과성 검증결과에서는 주효과모델보다 완충효과 모델의 연구가 적어, 향후 완충효과모델에 관한 연구의 필요성을 제시하였다.

미니탭(Minitab) 프로그램에 있는 실험계획법(Design of experiment)를 이용하여 박막실리콘 I-layer의 주효과 및 교호작용에 대한 연구를 실시하였다. I-layer의 주요 특성은 증착속도 및 전도도에 대하여 분석을 하였으며, 최종적으로 선택된 증착조건을 사용하여 비정질 실리콘 태양전지를 제조하여 확인 하였다. 실험설계는 2수준 5인자 완전설계요인법을 사용하였다. 분석결과 단막의 증착속도에 영향을 주는 주효과로는 Power와 E/S거리고 나타났으며, Power와 E/S거리, Power와 Pressure에서 큰 교호작용이 일어남을 확인 할 수 있었다. 암전도의 영향을 주는 주효과는 Sub. Temp.를 제외하고는 모두 영향을 주고 있었으며, 상당히 복잡한 교호작용을 이루고 있어 정확한 분석을 할 수는 없었다. 광전도도의 경우도 주효과에서 SiH4 flow rate를 제외하고는 모두 영향을 주고 있었으며, 복잡한 교호작용으로 정확한 분석이 어려웠다. 따라서 P-value를 분석하여 최종 R-제곱값이 증착속도는 97%이상의 높은 값을 얻었으나 전도도의 경우 최대차수 3차항으로 70~80%정도의 낮은 값을 얻었을 수 있었다. 낮은 값을 얻은 이유로는 실험설계시 몇몇 조건이 불안정한 plasma 상태로 인하여 전도도의 측정 편차가 커 분석오차가 높았을 것으로 추정된다. 암전도를 망소특성, 광전도도를 망대특성으로 광민감도 $10^5$으로 최적화 하여 비정질 태양전지를 만들어 평가한 결과 약 9%대의 광변환 효율을 얻을 수 있었으나 만족도 40%대의 낮은 값으로 향후 이와 관련한 더 정밀한 측정 및 분석이 요구된다.

This study employed multiple regression analysis and Two way ANOVA. The positive relationship between news fatigue and critical news use strategies was found. Exploring the factors to news processing strategies, the study suggested the potential direction of news education.

The conjoint analyst in marketing are anxious to know whether there exist synergy or antagonistic effects between two attributes. That is to say, they are interested in estimating the main effects as well as the two factor interaction effects.We research the design of survey questionnaire so that all the main effects and two factor interaction effects are estimable by employing the resolution V balanced Incomplete Block Fractional Factorial Design. We screen vital few effects, find the proper model and obtain information for efficient concepts optimization by analyzing all respondents survey data.

The purpose of this study was to compare kinematic variables between elite golfer and novice during golf putting. 23 elite golfers and 19 novice were participated, and SAM Putt was used to collect kinematic variables. To identify main effect and interaction effect, it was performed Two-way Mixed ANOVA at a significant level of a .05. Elite and novice group, follow-through was significantly different and indicated main effect between distance and skill level. Impact, backswing, and loft angle were significantly different and showed main effect between skill level. Also, backswing rhythm and impact timing were significantly different and indicated main effect between skill level. Therefore, minimizing the movement of the wrist and keeping the putting strike rhythm may improve the putting ability.

In $4{\times}4$ graeco-latin square design, powers of rank transformed statistic for testing the main effect are superior to powers of parametric statistic without regard to the effect structure with equally or unequally spaced effect levels as well as the type of population distributions such as exponential, double exponential, normal and uniform distribution. As numbers of block effect or effect sizes are decreased, powers of rank transformed statistic are much higher than powers of parametric statistic. In case that block effects are smaller than a main effect or one block effect is higher than other block effects, powers of rank transformed statistic are much higher than powers of parametric statistic in $4{\times}4$ graeco-latin square design with three block effects and one main effect.

Many universities stress gradually the importance of english-medium class in order to improve the international competitiveness and the internationalization of the university. In this paper, we compare english-medium class with korean class using course evaluation score. Also we analyze the factors that affect the effectiveness of the course evaluation score of english-medium class. First, logistic regression analysis is used to examine the main effects of subjects and individual characteristics. Also, decision tree analysis is used to examine the interaction effects for subjects and individual characteristics. The results of this paper are as follows. Grade, department category, class size, GPA and screening method affect the effectiveness of english-medium class. The highest effectiveness group of english-medium class is that grade is freshmen and department category is humanity. Also the group of the second highest effectiveness group is that grade is freshmen and department category is nature and art and GPA is high.

The purpose of this study is to verify the effects of gender and exercise participation types on depression and cognitive function in the elderly. The data of 10,059 elderly individuals who participated in survey on the welfare and living conditions of elderly individuals in 2017 were utilized for this study. The SGDS and the MMES-DS were used to measure their level of depression and level of cognitive function. The data were analyzed using the frequency analysis, the reliability analysis, and the two-way ANOVA. The results are as follows: first, the main effects of gender and exercise participation on depression are statistically significant. However, the interaction effect between gender and exercise participation is not significant. Second, the main effect of gender on depression is statistically significant. However, the main effect of exercise frequency on depression and interaction effect between gender and exercise frequency are not significant. Third, the main effects of gender and exercise hours on depression are statistically significant. However, the interaction effect between gender and exercise hours is not significant. Fourth, the main effects of gender and exercise participation on cognitive function are statistically significant. Additionally, the interaction effect between gender and exercise participation is significant. Fifth, the main effects of gender and exercise frequency on cognitive function are statistically significant. However, the interaction effect between gender and exercise frequency is not significant. Lastly, the main effects of gender and exercise hours on cognitive function are statistically significant. Moreover, the interaction effect between gender and exercise hours is significant. In conclusion, participating in exercise has shown to be beneficial for decreasing the level of depression and increasing level of cognitive function in elderly of both genders. An additional discovery made through this research is that women's level of cognitive function improves larger than men's when they participate in exercise.

This study investigated the relationship between social support and the well-being among the unemployed. Special attention was given to the empirical tests of the main effect and the stress buffering effect of social support on the psychosocial well-being and the practical implications in developing service strategies for the unemployed. Three-hundred-Sixty-nine(369) unemployed people in Choong-ju City and surrounding areas participated to the study. The results showed that both main and direct effects were partially supported by the data. In exploring the direct effect, social support from the family showed the strongest positive effect on the well-being of the unemployed. In the test of the stress buffering effect, the results showed a marginal buffering role of social support against the negative impacts of stress. Drawn from the results, the needs for further research in investigating the social support theory were suggested and possible implications for developing social work intervention strategies for the unemployed were identified.

The purpose of this study was to investigate how children's temperament and relationships with teachers affect their peer interaction. For this purpose, two surveys were conducted on mothers and teachers of 326 four- and five-year-old children attending four kindergartens in Gyeonggi Province. The data were analyzed by using PASW 18.0 to carry out hierarchical regression and post hocanalyses. The results showed that closeness to teachers moderated the effects of children's emotionality on their positive peer interaction. On the other hand, children's temperaments including emotionality and activity, and their relationship with teachers were directly influential on their negative peer interaction; no interaction effect was found between their temperament and relationships with teachers. It was concluded that the quality of teacher-child relationships could promote children's positive peer interaction while it could also reduce their negative interaction with peers. However, the temperament of children played limited roles in their negative peer interaction.
