This study is preliminary and qualitative research to find out the possibility of using children's architectural work as projective test tools. The features of 21 works from the activity of built-environment education for children was analyzed and compared with MBTI psychological preference types. The key results are as follows: 1) Observation and communication was required to understand and analyze children's architectural works. 2) The results of children's work appeared in various ways, and were classified as indicators according to composition, shape, expression, program, circulation. These indicators also showed the independence of personal expression types regardless of age or gender. 3) The comparison between architectural expressions and MBTI preference types revealed a significant relationship between the indicators. The relationship only appeared in certain indicator pairs. Therefore, it can be said that the built-environment education could be used as a projection test tool to understand the psychological preferences of children. In conclusion, the meanings and limitations of this study and the possibility of future researches were discussed.

The main purpose of this study was to investigate the relationships of children's creativity to field independence-dependence cognitive style and demographic variables at age 5. The subjects for the present study were 86 five-year-old boys and girls selected from two kindergartens in Seoul and their parents, who replied to the questionnaire about demographic variables. Children were tested in groups, with the Torrance tests of Creative Thinking-Figural, and individually with the Preschool Embedded Figures Test. The data were analyzed by one way ANOVA, t-test, and Pearson's product-moment correlations. Children's fluency and originality in creativity showed significant positive correlations with field dependent-independent cognitive style. There were no significant differences in creativity according to sex. There were significant differences in field dependent-independent cognitive style according to sex. The score of field independent cognitive style of boys were significantly higher than those of girls. Children's creativity showed low correlations with demographic variables.

Purpose: The purpose of this study was to evaluate effect of Thera-Band stretching exercise on flexibility of shoulder joint. Methods: The research deign was a experimental pre-post control group design. Sixteen subject were randomly divided into two groups; experimental group(n=8) and control group(n=8). Experimental group performed Thera-Band PNF stretching for 4 weeks and control group was not performed. To compare with the effectiveness of Thera-Band PNF stretching between two groups, I measured flexibility of shoulder joint with an Apley scratch test. The data were analyzed by Independence T-test. Results: The experimental group was significantly increased the flexibility at the right and left shoulder internal rotation. But the experimental group was not significantly increased the flexibility at the right and left shoulder external rotation. Conclusion: These result suggest that home-based exercise programs with Thera-Band can serve as a practical and effective means of flexibility gains in general people.

This research seeks to derive the design rainfalls through the L-moment with the test of homogeneity, independence and outlier of data on annual maximum daily rainfall in 38 Korean rainfall stations. To select the fit appropriate distribution of annual maximum daily rainfall data according to rainfall stations, applied were Generalized Extreme Value (GEV), Generalized Logistic (GLO) and Generalized Pareto (GPA) probability distributions were applied. and their aptness was judged Dusing an L-moment ratio diagram and the Kolmogorov-Smirnov (K-S) test, the aptitude was judged of applied distributions such as GEV, GLO and GPA. The GEV and GLO distributions were selected as the appropriate distributions. Their parameters were estimated Targetingfrom the observed and simulated annual maximum daily rainfalls and using Monte Carlo techniques, the parameters of GEV and GLO selected as suitable distributions were estimated and. dDesign rainfallss were then derived, using the L-moment. Appropriate design rainfalls were suggested by doing a comparative analysis of design rainfall from the GEV and GLO distributions according to rainfall stations.

The purpose of this study was to investigate the effects of meditation music with lumbar stabilization exercise on balance, concentration and muscle activation. Participants are divided into Group A and Group B. Group A listened to meditation music while doing 4 sets of lumbar stabilization exercise. Group B did not listen to meditation music while doing 4 sets of lumbar stabilization exercise. Surface EMG data was obtained rectus abdominis, external oblique, erector spinae, multifidus muscle during lumbar stabilization exercise. To examine the effect of before-after experiment for concentration and balance, paired t-test was adopted. Changes in EMG data of each muscles were analyzed by independence t-test. There were statistically significant increasing at concentration level and balance level in Group A. But significant difference was not shown in muscle activation. The clinical effect of the meditation music with lumbar stabilization exercise was investigated in this study with more excellent results in concentration and balance. In conclusion, these results suggest that meditation music and lumbar stabilization exercise may be useful in elderly people.

The purpose of this study was to examine mother's child rearing practices by mothers of their first-born child as a function of child's sex, temperament, and social class and of mother's marital satisfaction. The subjects were 158 mothers of 3-year-old first-born children in Seoul. Block (1984)'s CRPR, Buss and Plomin (1975)'s EAS, and Roach et al.'s MSS (1981) were used to measure maternal child rearing practices, children's temperament, and mother's marital satisfaction, respectively. The statistical methods for data analysis included t-test, ANOVA, Duncan's multiple range test, multiple regression. The major findings showed there were no sex of child differences in child rearing practices. Social class differences were found in "encouragement of independence", "enjoyment of child" and "openness to experience" in maternal child rearing practices. There were differences in maternal child rearing practices by child's temperament and mother's marital satisfaction. In a multiple regression analysis, it was found that the most significant predictor of maternal child rearing practices was mother's marital satisfaction.

In order to examine whether the difference between two point estimates of population proportions is statistically significant, data analysts use two techniques. The first is to explore the overlap between two associated confidence intervals. Second method is to test the significance which is introduced at most statistical textbooks under the common assumptions of consistency, asymptotic normality, and asymptotic independence of the estimates. Under the null hypothesis which is two population proportions are equal, the pooled estimator of population proportion is preferred as a point estimator since two independent random samples are considered to be collected from one population. Hence as an alternative method, we could obtain another confidence interval of the difference of the population proportions with using the pooled estimate. We conclude that, among three methods, the overlapped method is under-estimated, and the difference of the population proportions method is over-estimated on the basis of the proposed method.

This Study examines the implications for event studies using the daily stock data. The output present the event study results. The event period is defined from 30 days before through 30 days after the event date, and is broken into four "windows" for abnormal return cumulation: the pre-event period, days -30 through -2; dajys -1 and 0, a period commonly investigated for the immediate impact of the event; and the post-event period, days +1 through +30. It shows how firm's information offerings affect the price process and consequent issues. The Patell Z test is an examples of a standardized abnormal return approach, which estimate a separate standard error for each security-event and assumes cross-sectional independence. The generalized sign test adjusts for the fraction of positive abnormal returns in the estimation period instead of assuming 0.5.
