Concentrations of the principal volatile organic compounds, such as benzene, toluene, ethylbenzene, m,p,o-xylene, styrene, and chlorobenzene were measured at the solid waste treatment plants classified into four categories; municipal waste incinerator, municipal waste landfill site, industrial waste incinerator and industrial waste landfill site. The average concentration of VOCs in industrial waste treatment facilities was 33.43 ppb and was significantly higher than that measured at municipal waste treatment facilities (4.71 ppb). The average toluene concentrations measured at incinerators (13.05 ppb) were a little higher than those measured at landfill sites (11.54 ppb). The contribution of the waste treatment facilities to the concentration of benzene (0.35 ppb) and o-xylene (0.15 ppb) in the industrial area was relatively small. However, toluene measured in the industrial waste treatment facilities was the most abundant VOCs with the average concentration of 21.37 ppb. As a result of analyses of fingerprint, in cases of IISH and ILUS, a variety of compounds other than major VOCs were detected in high level. On the Pearson correlation analysis, the correlation was generally positive and some pairs of these VOCs were very strongly correlated (correlation coefficient > 0.75).

This study was attempted to provide basic data for health promotion program for depressive relief by grasping the degree of depression of adult women and grasping the factors affecting depression. Data were collected using structured questionnaire for 249 adult women in the one marine city and analyzed through technical statistics, Pearson correlation coefficients and multiple regression analysis. According to the study, 76.3 percent (190 people) of women in the city were depressed. The subjects who expressed depression showed negative correlations with social support, self-respect and subjective euphoria and between depression and stress as positive correlation. The result of multiple regression analyses to identify the effects of depression have shown that stress is a major influencing factor, and this model has a 21.1% explanatory power. Therefore, the study found stress as a significant factor in the depression of adult women, it is necessary to develop and apply health promotion programs that can reduce stress in order to reduce depression in adult women.

Purpose: This study was designed to explore the relationship of depression with stress, anxiety and mindfulness in nursing students in 2010. Methods: A cross-sectional design was used and data was collected through structured questionnaires. Depression, stress, anxiety, and mindfulness were measured by using the Depression, Anxiety and Stress Scale (DASS) and the Mindfulness Attention Awareness Scale (MAAS). The data were analyzed using t-test, one-way ANOVA, Pearson correlation coefficient, and stepwise multiple regression. Results: A total of 131 nursing students participated in this study. Depression was positively associated with stress (r=.81, p<.001) and anxiety (r=.76, p<.001), and negatively associated with mindfulness (r=-.73, p<.001). Multiple regression analyses showed that in different type of residence, anxiety and mindfulness were statistically significant predictors of depression with explanatory power of 67%. Conclusion: When nurse instructors manage depression among nursing students, the strategies need to address stress, anxiety, and mindfulness. This study may help nursing students to better manage their depression.

Purpose: The study was undertaken from June 1 to July 15, 2008 to assess the effect of social support on self-esteem and life satisfaction in elderly volunteers. Methods: Social support, self-esteem, and life satisfaction were determined using previously established and accepted methods. Data analyses included frequency, ANOVA, t-test, Pearson correlation coefficient, and simple regression. Results: Subjects' social support, self-esteem, and life satisfaction were closely related. The relationships of social support/self-esteem, social support/life satisfaction, and self-esteem/life satisfaction were significant. Social support accounted for 15% of self-esteem and 12% of life satisfaction. Conclusions: Social support is a very important factor influencing self-esteem and life satisfaction of the elderly. Social support, which sustains the mental health of the elderly, represents one of the best strategic nursing interventions.

This study was to identify the factors of ethical values in nursing students. The survey was conducted in two nursing colleges (n=180) using self-reported questionnaire. The data were analyzed with descriptive statistics, t-tests, ANOVA, Pearson's correlation coefficient and multiple regression analyses using SPSS/WIN 21 software. Influencing factors of ethical values were empathy(t=3.436, p=.001), teaching method except lecture(t=3.037, p=.003), and curriculum track at high school(t=2.309, p=.022). The model was statistically significant explaining 16.2% of the variance (F=11.185, p<.001). This study suggests that strategies for increasing nursing students' ethical values include reinforcing empathy, utilizing various type of teaching method except lecture in nursing ethics class, and allowing high school students applying to college of nursing regardless of their curriculum track.

The purposes of this study were to determine the functions of actions of the limbs during each of the three support phases of the triple jump and their relationships with the performance of the triple jump. Four elite male triple jumpers were participated as subjects. The statistical analyses used were the Pearson product moment correlation coefficient for establishing relationships and simple regression analyses to determine and compare the relationships between the change of the horizontal velocity and the change of the vertical velocity during different support phases. A level of significance at p<.05 was set. The actions of the arms were responsible for about 25%, 25%, and 30% of the decrease in the horizontal velocity of the whole body center of gravity during the support phases of the hop, step, and jump, respectively. The change in the velocities of the whole body center of gravity due to the actions of the free limbs were significantly related with the whole body center of gravity during each support phase. The action of the support leg was associated with the decrease in the horizontal velocity and the increase in the vertical velocity of the whole body center of gravity during each support phase.

To search and development a new material with superior melanogenesis inhibitory activity, the bioactivities (obs. pl$_{50}$) of alkyl-3,4-dihydroxybenzoyl esters and N-alkyl-3,4-dihydroxybenz-oyl amides as substrate molecules were measured in mouse melanoma cells. And also, we have studied that 3-D QSARs (3 dimensional Quantitative Structure-Activity Relationships) between molecular interaction field of substrates and the bioactivities were analyzed using CoMFA (Comparative Molecular Field Analyses) method. When cross-validation value (q$^2$) is 0.68 at 3 components, the Pearson correlation coefficient ($r^2$) is 0.900. From the basis on the findings, the model was appeared by the contour map such as steric field and electrostatic field relationships between quantitative structure and the bioactivity of the various substrate derivatives. Measured bioactivities (obs. pl$_{50}$) of unknown compounds are very similar to predicted activity (pred. pl$_{50}$) according to the CoMFA model. As the results of prediction, we could conclude that the bioactivities were increased by creation of R$_1$ substitution of 5,5-dime-thylhexoxy, 6,6-dimethylheptyl, 1-amino-6,6-dimethylheptyl group etc and R$_2$ substitution of hydroxy, methyl, methoxy group etc.p etc.

Purpose: This study was conducted to identify the influence of clinical practicum-related stress, and awareness, and self-efficacy on strength on health promotion behaviors among nursing students. Methods: The subjects were 274 students in nursing college who had experience in a clinical nursing practicum. Data were collected from self-reported questionnaires and were analyzed by independent t-test, ANOVA, Pearson correlation coefficient, and multiple regression analyses. Results: Multiple regression analyses showed that strength self-efficacy and self-awareness on strength significantly affected overall health promotion behaviors. Regarding subscales of health promotion behaviors, self-awareness on strength significantly affected health responsibility and stress management in health promotion behavior when controlling for sociodemographic characteristics, while the subscales of clinical practicum-related stress did not affect health promotion behavior. Conclusion: The recognition of an individual's strength and self-efficacy might be a factor in improving health promotion behaviors among nursing college students, although they suffer from stress during clinical nursing practicum.
