The purpose of this study was to identify the relationships between vanity and materialism and fashion orientation. This study identified underlying factors of vanity and then grouped respondents into clusters based on the low factors of vanity. This study also examined their materialism and fashion orientation according to clusters. Data were gathered by surveying university students living in Seoul metropolitan area using convenient sampling, and 313 questionnaires were used in the statistical analysis. In analyzing data, factor analysis, cluster analysis, t test, correlation, and one-way ANOVA were conducted. Regarding vanity, low factors, 1) a concern id. physical appearance, 2) a positive view of physical appearance, 3) a concern for achievement, and 4) a positive view of achievement, were identified. Correlation analysis showed all four factors of vanity were significantly related with underlying dimension! of materialism and fashion orientation. Based on the factor scores, three clusters were identified. There were also significant differences in the dimensions of materialism and fashion orientation according to the clusters.

Purpose: To examine the relationships between self-care, social support, and biological markers in liver transplant recipients. Methods: The participants included 118 liver transplant recipients who visited outpatient clinic at Y University Hospital in Seoul from April to May, 2013. Questionnaires consisted of self-care and social support scales. The biological markers were collected by reviewing electronic medical records. Data were analyzed with descriptive statistics, t-test, ANOVA with Scheff$\acute{e}$ post-hoc test, and Pearson's correlation. Results: The self-care score was significantly higher in a patient group within 6 months post-transplant when compared to a patient group post-transplant 3 to 5 years (F=3.10, p=.018). The self-care showed positive correlation with social support with statistical significance (r=.36, p<.001). Conclusion: As the self-care in liver transplant recipients had a positive correlation with social support from family and healthcare providers, the development of comprehensive long-term nursing intervention systems including counseling, education, and support in consideration of progress of time period after transplantation is necessary to enhance self-care behaviors among this population.

Soil moisture plays a pivotal role in hydrological processes, especially in the forest which covers more than 64% of the national land. Soil moisture was monitored to analyze soil moisture change characteristics in terms of time and soil layers in this study. 2 Years soil moisture change data was obtained from the experimental nut pine forest and statistical analysis including auto-correlation and cross-corelation among soil moisture data from different soil layers was conducted. Using the monitored soil moisture data, a relationship between soil moisture change and precipitation was analyzed and seasonal soil moisture change characteristics were analyzed. From the result of inter-relationships among soil layers in terms of season and time lag, soil moisture change characteristics in the nut pine forest were upper soil layers were much sensitive than lowers, and seasonal variation if soil moisture for upper soil layers were bigger than lowers showing low correlation with precipitation in winter and spring due to freezing and snowfalls.

Purpose: The purpose of this study was to identify the relationships among emotional labor, empowerment, job burnout, and turnover intention. Methods: The design of this study was a cross-sectional descriptive study. The subjects of this study were 358 nurses working for over 6 months in Seoul and Gyeonggi-do. The data were collected from 4th to 30th of September, 2009 through one-to-one interviews. Survey data were analyzed using t-test, one-way ANOVA, Pearson's correlation coefficient, and hierarchical regression. Results: We find the positive correlation of turnover intention with emotional labor and with job burnout, but the negative correlation of empowerment with job burnout and with turnover intention. The nurses' turnover intention scores were relatively low with 1.30. Job burnout, shift work, and frequency of turnover were predictors of turnover intention. The most powerful predictor variable was job burnout (${\beta}$=.420, p<.001). We find that emotional labor and empowerment as determinants of turnover intention are not significant. Conclusion: These results suggest that manager should consider shift work of nurses and job burnout in order to manage nurse organization and resource effectively.

Background: In this study prognostic correlations of histopathologic parameters and the Ki-67 proliferation index and as well as the diagnostic value of immunohistochemical markers in pheochromocytomas were evaluated. Materials and Methods: A total of 22 patients diagnosed with a pheochromocytoma between 2000-2010 in Izmir Katip Celebi University Ataturk Training and Research Hospital were included. Diagnostic value of the PASS scoring system, and prognostic correlations of histopathologic parameters and Ki-67 proliferation index were investigated. SPSS for Windows 17.0 software was used for statistical analysis. Results: There was no statistically significant correlation between recurrence and clinicopathologic parameters or the PASS score (PASS>4). In addition, there were no statistically significant correlations between PASS score and clinicopathologic parameters, such as diameter (5 cm), weight (>100g), gender (female/male ratio) and age (25-45/45-55/>55). Besides, there were no significant correlation between diameter and clinicopathological parameters and also recurrence. However, there was a statistically significant correlation between Ki-67 proliferation index and capsule invasion (p=0.047). Conclusions: Some but not most of the findings in our study were concordant with the literature. To clarify relationships, investigations with standard scoring systems which are not affected by subjective factors and feature appropriate histopathological criteria should be made on larger study groups.

In this study, we constructed a four-channel impedance measurement system including a two-channel goniometer to analyze human arm movement. Impedances and joint angles were simultaneously measured for wrist and elbow movements. As the impedance changes resulting from wrist and elbow movements depended heavily on electrode placement, we determined the optimal electrode configurations for those movements by searching for high correlation coefficients, large impedance changes, and minimum interferences in ten subjects (age: 29+6). Our optimal electrode configurations showed very strong relationships between the wrist joint angle and forearm impedance (correlation coefficient = 0.95+0.04), and between the elbow joint angle and upper arm impedance (correlation coefficient = -0.98+0.02). Although the measured impedances changes of the wrist (1.1+1.5 ohm) and elbow (-5.0+2.9 ohm) varied among individuals, the reproducibilities of wrist and elbow impedance changes of five subjects were 5.8+1.8 % and 4.6+1.4 % for the optimal electrode pairs, respectively. We propose that this optimal electrode configuration would be useful for future studies involving the measurement of accurate arm movements by impedance method.

The purpose of this study is to examine how the rural elderly assess the multi-dimensions of health. This includes the physical, mental and social dimensions of health, correlations among them, and whether there are gender differences and age-group (60's, 70's, 80 and over) differences. For this purpose, survey data was gathered from 881 rural elderly who live in a village. The statistical methods used for data analysis were descriptive statistics, t-test, ANOVA and correlations. The major findings of this study are as follows: Physical health was measured by self-rated health, ADL, IADL, and farmer symptoms. The respondents classified as 80 and over and female perceived their physical health more negatively. Mental health was perceived somewhat positively in general but female participants perceived their mental health more negatively than males. Social health of the rural elderly was relatively positive in comparison to the other dimensions of health. The rural elderly engaged in many social activities, and the majority of them had many social support networks composed of more than 12 persons. Relationships among the physical, mental and social health dimensions were different. The correlation of physical and mental health and the correlation of social and psychological health were statistically significant. However, the correlation of physical and social health had no significant meanings.
