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.

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.

This study examined the aspects in elementary school students' career interest and career awareness by gender, age, and multi-cultural families/general families. The subjects were 341 elementary school students from multi-cultural families and general families. The results were as follows. First, there were significant differences in investigative, artistic, and social interests by gender. The children from multi-cultural families and general families showed no significant differences in career interest. Second, the children from general families had higher scores than those from multi-cultural families in self-awareness, occupational exploration, career attitude, and career awareness. And the girls had higher scores than boys in self-awareness, occupational exploration, and career awareness. Third, there were meaningful differences in career interest and career awareness by age. The younger children had higher scores in career interest and lower scores in career awareness. Fourth, the career interests had significant correlations with career awareness in both groups. And there were stronger correlations in general children. Fifth, the regression analyses showed that career interests had significant effects on career awareness in both groups, and there were higher effects in general children. The artistic interests in multi-cultural children and the social interest in general children had significant effects on career awareness. And the effect of multi-cultural families/general families was noticeable in occupational exploration, career attitude, and career awareness. The implication for multi-cultural career education and counseling practice are discussed based on the result of the present study.

한국어에서 어절은 띄어쓰기 단위이며 한국어의 두드러진 특징 가운데 하나이다. 본 연구에서는 명사에 조사가 결합된 명사어절의 처리 과정에 대해서 밝히고자 이 과정에 관여하는 빈도효과를 측정하였다. 즉, 명사의 빈도와 어절의 빈도를 조작하여 어절의 의미를 판단하는데 걸리는 반응시간을 측정하였다. 실험 결과, 자극을 제시한 방법에 차별을 둔 실험 1과 실험 2의 결과에서 모두 어절빈도의 주효과가 유의미한 것으로 관찰되었다. 그러나 명사빈도의 주효과는 실험 2에서만 관찰되었고, 상호작용효과는 실험1과 실험2 모두 관찰되지 않았다. 또한, 한국어의 어원에 따른 즉 다시 말해, 한국어 명사를 한자어, 고유어, 외래어로 분류하여 어원에 따른 심성어휘집 표상 양식의 차이를 구별하여 보고 이를 토대로 더욱 세부적인 한국어 명사어절의 처리 과정을 규명하여 보고자 한다.

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.

The purpose of this study was to examine the influence of the exercise performance of yoga and pilates on the autonomic nervous system in an effort to provide some clinical information on exercise prescription. The subjects were 20 selected college students who majored in P.E. A yoga group and a pilates group were organized with 10 students respectively, the autonomic nervous system of the students was measured before the exercise, immediately after that and 30 minutes after recovery. The findings of the study were as follows: First, there were significant differences in the yoga group's stress index and average pulse according to the main effect of the time and interaction effect between the time and group. Second, there were significant differences in the yoga group's sympathetic nervous system activity and autonomic nerve balance according to all the main effect of the time, interaction effect between the time and group and the main effect of group. Third, there were significant differences in HRV(Heart Rate Variability), parasympathetic nervous system activity, SDNN, and RMSSD according to the main effect of the time, and interaction effect between the time and group and the main effect of group produced no statistically significant differences. In conclusion, yoga seemed to be effective at lowering stress index and average pulse. Specifically, yoga exercise seemed to exert a more positive influence on the decrease of sympathetic nervous system activity and autonomic nerve balance than pilates exercise.

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.

When there is no main effcts or only one main effect in a $2 \times 2$ factorial design, Type I error rates and power for the rank transformed F test (FR test) for interaction are nearly equal to those of the classical F test. However the power of FR test is quite superior under the exponential distribution rather than the of FR test is quite superior under the exponential distribution rather than the normal distribution. Meanwhile when both main effects are in the model, Type I error rates of FR test, compared with those of F test, decrease as the effect size increases and are dependent on the fashion in which main effects are constructed. In addition, the power of FR test increases as the effect size and the sample size increase and is highly dependent on the manner in which main effects are constructed and the type of population distribution.
