Objectives : This study was conducted to examine the relationships between Korean adult's daily hours of sleep, depression, and suicidal thoughts using data from the 7th National Health and Nutrition Survey. Methods : This study utilized a depression screening tool, the 9-item Patient Health Questionnaire (PHQ-9), for the 6,355 participants of the health and mental health survey. T-tests, cross analysis, correlation analysis, and logistic regression analysis were used. Results : The results showed that sufficient hours of sleep decreased depression. The depression score for females (3.19) was significantly higher than for males (2.10; p<.001). The participants in the depression group slept less than 7 hours per day (p<.01). Conclusions : The study results showed a significant correlation between sleep duration and depression when health-related factors and social factors influencing sleep were controlled. The results also indicated that this correlation may vary based on gender. This study implies that further studies are necessary to identify the causal relationship between sleep duration and depression.

GEV분포는 세계 여러 나라에서 홍수와 극한강우 등의 빈도분포로 널리 활용되고 있다. L-모멘트법은 GEV분포의 매개변수 추정을 위해 일반적으로 사용되고 있는 추정법이다. 본 연구에서는 Monte Carlo 실험을 이용하여 GEV분포를 따르는 서로 다른 두 지점의 자료의 교차상관계수를 이용하여 L-모멘트 추정값인 L-변동계수와 L-왜도계수들 간의 교차상관계수를 Simple Power 함수를 이용하여 유도하였다. 실험과정에서 생성된 비현실적이며 실험결과에 큰 영향을 미치는 음수값들을 배재한 GEV+분포를 이용하였다. 결과로, Simple Power 함수가 두지점간 자료의 교차상관과 L-모멘트 추정값들간의 교차상관 계수의 관계를 잘 모사하고 있음을 확인하였다. 다양한 GEV 분포의 매개변수 조합에 대한 Simple Power 함수의 매개변수 추정값과 정확성은 표로 제시하였다. 또한 위 연구결과를 활용할 수 있는 Generalised Least Square(GLS) 지역회귀 기법에 대해 설명하였다. 따라서 본 연구에서 도출된 관계식은 향후 GLS 회귀식을 이용한 GEV 분포의 지역 매개변수를 추정하는데 있어 L-모멘트 추정값들간의 정확한 교차상관관계를 제시할 수 있을 것으로 기대한다.

The early childhood is a pivotal period for the development of creativity since creative imaginary is rich at the age from 4 to 4.5 years old, The purpose of this study is to examine the relationships between children's creativity, playfulness and multiple intelligence. 91 children(41 boy, 50 girls) attending preschool in jeon-ju city were participated in this research, The age of children was 6 years(average 73.7 months), After collecting the data to find the connections between children's creativity, playfulness and multiple intelligence from the subjects' data using the SPSS WIN 10.0 program, along with t-test, ANOVA and Pearson's correlation in this paper. 1. There was significant correlation between children's playfulness and creativity. Intelligence spontaneousness the element of the playfulness has a correlation with Creativity strengths, Elaboration. In addition, Resistance to Premature Closure has a correlation with social spontaneity, And Originality has a correlation with the Expression of Pleasure the element of the playfulness, 2. There was a significant positive correlation between children's multiple intelligence(MI) and creativity, Fluency the element of creativity has a correlation with Interpersonal intelligence the element of multiple intelligence: And Originality has a correlation with Bodily-kinesthetic intelligence, Intrapersonal intelligence the element of MI. In addition, Abstraction of Titles has a correlation with Intrapersonal intelligence. 3. There was a little correlation between children's MI and playfulness. The Expression of Pleasure has a correlation with bodily-kinesthetic intelligence, Based on the current study, the relationships between creativity, playfulness, and multiple intelligence could be identified. Especially, creativity was significantly correlated with playfulness and multiple intelligence of early childhood. Therefore, it was found that creativity of toddler might be essential factor for the development of toddler's cognitivity.

Quantitative strucrure-activity relationships between the toxicity (LD$\_$50/) and molecular properties of amine and nitro compounds were tested. The all 19 compounds showed low correlations below 0.500 to their LD$\_$50/ values. When amine or nitro compounds were taken separately, the correlation between the calculated chemphysico parameters and LD$\_$50/ were also poor (r$^2$=0.4911, 3967 repectively). The overall relationships among the QSAR parameters were investigated. Molecular weight shows a high correlation with total surface area (r$^2$=0.9287); 0.9090 for zero-order connectivity and second-order connectivity : 0.8784 for bioconcentration factor and second-order connectivity. When amine compounds were taken to perform the statistical treatment, the relationships between parameters were as follows: 0.8436 for volume-negentropy; 0.8925 for volume-bioconcentration factor; 0.9929 for zero-order connectivity-Kow; zero-order connectivity-bioconcentration factor; 0.9141 for zero-order connectivity-solubility; 0.9718 for solubility-bioconcentration factor; 0.9894 for solubility-bioconcentration factor and 0.9319 for Kow-bioconcentration factor. On the other hand, nitro compounds showed different relationships as follows: 0.8952 for volume-I/O character; 0.9520 for volume-total surface area: 0.9351 for volume-molecular weight; 0.9351 for volume-MW; 0.9961 for Kow-Koc; 0.8455 for Kow-bioconcentration factor; 0.8879 for Koc-bioconcentration factor; 0.9987 for MW-total surface area respectively.

This study investigated the effects of multi-culture acceptability and multi-culture teaching efficacy on young child-teacher relationships. The teachers' attitude towards multi-culture education was included in the analysis as a mediator between multi-culture acceptability and multi-culture teaching efficacy. Participants were 295 teachers and 295 young children between 3 and 5 years in childcare centers located in Seoul, Incheon, Ulsan, Gyeonggi, and North Gyeongsang Province. Teachers completed questionnaires regarding multi-culture acceptability, multi-culture teaching efficacy, and attitude towards multi-culture education. Collected data were analyzed by descriptive statistics, Pearson's correlation, Structural Equation Model, and Sobel test with SPSS ver. 18.0 and AMOS ver. 21.0. The results were as follows. First, the subscale of multi-culture acceptability and multi-culture teaching efficacy generally showed a positive correlation with closeness and conflict in the subscale of young child-teacher relationships. Second, teacher's multi-culture acceptability directly influenced the young child-teacher relationship. In addition, the impact of multi-culture teaching efficacy on young child-teacher relationship was mediated perfectly by the multi-culture education attitude. The results suggest that the multi-culture teaching efficacy promote early childhood multicultural education attitudes and that can be changed to positive teacher relationships.
