This study examines the relationships among the leadership of hotel managers, organizational culture, and business performance with an empirical analysis. The results of analyzing various factors are as follows. Leadership can be divided into 'democratic leadership' and 'authority leadership'. Organizational culture can also be divided into 'adhocracy culture', 'clan culture', 'hierarchy culture', and 'market culture' while business performance into 'nonfinancial performance' and 'financial performance'. After that, canonical correlation analyses between leadership and organizational culture, organizational culture and business performance, and leadership and business performance were conducted.

This study examined the relationships among maternal psychological life position, involvement in child-rearing and children's emotional intelligence. The subjects were 267 four and five-year-old children and their mothers from five child care centers located in Seoul. Children's emotional intelligence was assessed by the teacher rating scale developed by Kin(1998) and questionnaires were used to assess the maternal psychological life position and involvement in child-rearing. Data was analyzed by t-test, Pearson's correlation, and stepwise multiple regression. Results demonstrated a correlation between the level of the children's emotional intelligence and their gender and age. The strongest predictor of children's emotional intelligence was the child's age.

The purpose of this paper is to represent values of acoustic cues for Korean oral stops in the multi-dimensional space, and to attempt to find possible relationships among acoustic cues through correlation coefficient analyses. The acoustic cues used for differentiation of 3 types of Korean stops are closure duration, voice onset time and fundamental frequency of a vowel after a stop. The values of these cues are plotted in the two and three dimensional space and see what the critical cues are for complete separation of different types of stops. Correlation coefficient analyses show that there are statistically significant relationships among acoustic cues but they are not strong enough to make a conjecture that there is a possible articulatory relationship among the mechanisms employed by the acoustic cues.

A total of 227 children and their mothers participated in this study of the relationships between mother's thinking style and parenting self-efficacy and between parenting self-efficacy and children's social competence. Data were gathered with Thinking Style Scale Questionnaire, Parenting Self-efficacy Scale, and Social Competency Scale: Preschool. Correlation and multiple regressions were used for data analyses. A statistically significant correlation between mother's thinking styles and parenting self-efficacy and between mother's parenting self-efficacy and children's social competence emerged. That is, mothers whose thinking styles were legislative, hierarchical, and liberal had more parenting self-efficacy, and children whose mothers felt more confidence in their parenting had a higher degree of social competence.

Compression index is one of the important characteristic numbers in soft soil engineering. Since 1940's, many researchers have suggested various practical solutions to define the compression index of clay using other soil properties. But, these results are only can give us an outline of soft soil behavior. In this study, the relationships between pore water pressure dissipation test results and compression index were suggested using comparison results of both tests. This relationships are based on basic concept of consolidation phenomena, essential difference between pore water pressure dissipation test and consolidation test, and disagreements between theoretical time factor and real time factor. To identify proportional factor of proposed equation, Geotechnical investigation results of Kwang-Yang(KY) site and Busan New Port(BN) site were used. The proportional factor was 0.0031 from 20 to 50% of consolidation rate where correlation parameter($R^2$) is 0.9051.

Purpose: The study investigated the relationships among perceived stress, mental health, and social support in community residents. Method: A self-reporting questionnaire was completed by 302 community residents aged 19-64-years-of-age from October 7 to November 30, 2008. Assessment tools were an The established perceived stress scale, standardized mental health scale, and established social support scale. The data was analyzed by descriptive statistics, t-test, one-way ANOVA, Scheffe's test, and Pearson's correlation coefficient using the SPSS WIN 12.0 program. Result: Significantly negative correlations were evident between perceived stress and social support, and between social support and mental health. But, there was a significantly positive correlation between perceived stress and mental health. Conclusion: It is necessary to develop a strategy to decrease perceived stress, improve mental health, and increase social support for community residents.

This paper is to analyze the effect of demographic factors on children' wear buying pattern, media and information utilization, and design preference. A total of 355 usable data was collected from house wives in three metropolitan cities(Seoul, Daejon, Bundang) in Korea. Correlation analysis showed that there were statistically significant correlation between demographic factors and clothing buying behavior, information utilization, and design preference. Also, Regression results showed that 8 Demographic Factors are significant predictors. The results with ANOVA showed that there were significant relationships between PURCHASE OCCASION and DISPLAY INFORMATION UTILIZATION, and showed that there were significant relationships (F=28.625, p=<.001) between PURCHASE MOTIVATION and SALES PERSON ADVICES UTILIZATION. Thus, both visuality and friendliness of service were affected by consumers. Considering the increasing importance of service quality in the retail VMD, sale promotion should be enhanced and sale person is needed to be trained to be friendly to all consumers regardless of product composition

We investigated the structure-activity relationships on use of multi-layer neural networks. The relationships are techniques required in developments of medicines. Since many kinds of observations might be adopted on the techniques, we discussed some points between the observations and the properties of multi-layer neural networks. In the structure-activity relationships, an important property is not that standard deviations are nearly equal to zero for observed physiological activity, but prediction ability for unknown medicines. Since we adopted non-linear approximation, the function to represent the activity can be defined by observations; therefore, we believe that the standard deviations have not significance. The function was examined by "leave-one-out" method, which was originally introduced for the multi-regression analysis. In the linear approximation, the examination is significance, however, we believe that the method is inappropriate in case of nonlinear fitting as neural networks; therefore, we derived a new index fer the relationships from the differential of information propagation in the neural network. By using the index, we discussed physiological activity of an anti-cancer medicine, Mitomycine derivatives. The neuro-computing suggests that there is no direction to extend the anti-cancer activity of Mitomycine, which is close to the trend of anticancer developing.

The purpose of this study was to examine the effects of householder's job status m the family life style. Data was collected from 475 parents in Chonbuk province by using a self administered questionnaire from June 10 to 30, 1998. Frequencies, percentages, and averages were calculated T-test, Pearson's correlation coefficients, and stepwise multiple regression analysis were followed. The results were as follows; 1. The families who suffered householders' job loss were 1/4 of the respondents and over 4/5 of the families felt economic stresses. 1/3 of the respondents had debts and 1/5 had not any savings. Most of the families were in good or normal marriage relationships, experienced economic crises, and had sparing habit. 2. In out-of-job families, couple cohension, couple satisfaction, and total marriage relationships were lower than in-job families. Also, out-of-job families spared more in buying and using clothes and foods, total clothes living and total food living. 3. In out-of-job families, the economic pressures on marriage relationships, clothes living, and food living were stronger than in-job families. 4. Family resources such as savings, ordinary marriage relationships, and sparing habit effected on the marriage relationships, clothes living, and food living in out-of-job families and in-job families.
