Purpose: This study was done to explore the levels of depression experienced by adolescents, and to compare health behavior between depressed and non-depressed adolescents. Method: Participants were chosen by a stratified random sampling of adolescents in the second grade of a high school in P city. Levels of depression and health behavior of the students were measured using questionnaires. Data collection was done in May, 2002. Data were analyzed with descriptive statistics and logistic regression using the SPSS WIN 10.0 Program. Results: The prevalence of depression (CES-D) among the students was $53.5\%$. In multiple logistic regression analysis, sex (OR 1.80, $95\%$ Cl 1.35-2.41), school performance, mid (OR 1.68, $95\%$ Cl 1.48-1.97) and low (OR 1.42, $95\%$ Cl 1.29-1.61), drinking (OR 1.47, $95\%$ Cl 1.09-1.98), and not eating breakfast (OR 1.74, $95\%$ Cl 1.56-1.97) were significantly higher in students in the depressed group than those in the non-depressed group. Conclusions: Based on the findings, we concluded that many adolescent experience depression and depression in adolescents is significantly related to behaviors of smoking, alcohol, no exercise, and not eating breakfast. However this study did not address causality among these variables. There, further research, such as a longitudinal study, is needed to identify causality among the variables.

Purpose: The purpose of this study was to investigate occupational stress and fatigue level of neonatal nurses and to assess relationship between the two of them. Methods: Subjects were 109 neonatal nurses working at 2 university hospitals and 9 women's hospitals in D city, and the data were analyzed using descriptive statistics and binary logistic regression analysis by the SPSS/WIN 15.0. Results: The mean score of nurses' occupational stress level was 3.22, and the highest was 'night shift' among the 7 subcategories, and fatigue level was 62.0, and the highest was physical fatigue in configuration field. In logistic regression analyses, 'heavy workload' and 'inadequate physical environment' led to most occupational stress. Conclusion: In addition to significantly higher levels of occupational stress of neonatal nurses, the cumulative fatigue also resulted in decreased quality of nursing, job satisfaction and nursing productivity; therefore, appropriate number of nurses and improvement of work environment is necessary. Furthermore, to reduce the occupational stress and fatigue, we should try to develop adequate clinical guidelines and intervention strategies and apply them in neonatal care unit.

Purpose: The purpose of this study was to identify the potential risk factors - children's factors, parental factors, and familial-environmental factors - with respect to overweight and obesity in Korean preschool children. Methods: This study used a descriptive cross-sectional design and involved 264 pairs of mothers and preschool children aged 3-5 years (121 boys, 143 girls) attending daycare centers in C city. Multiple logistic regression analyses were used to identify significant risk factors for overweight and obesity in preschool children. Results: According to the multivariate logistic regression, family history of diabetes mellitus as children's factors, overweight or obesity of both parents as parental factors were significantly associated with an increased likelihood of overweight and obesity in preschool children. In addition, lack of community space for physical activity as familial-environmental factors was significantly associated with increased likelihood of overweight and obesity. Conclusions: Health care providers should concerned with the risk of overweight and obesity in children with high risk familial factors, such as family history of obesity and diabetes mellitus. Moreover, policies should be set in place to make sure communities include space that foster physical activity in young children.

To predict urban growth according to changes in landcover, probability factors werecal culated and mapped. Topographic, geographic and social and political factors were used as prediction variables for constructing probability maps of urban growth. Urban growth-related factors included elevation, slope, aspect, distance from road,road ratio, distance from the main city, land cover, environmental rating and legislative rating. Accounting for these factors, probability maps of urban growth were constr uctedusing frequency ratio (FR) and logistic regression (LR) methods and the effectiveness of the results was verified by the relative operating characteristic (ROC). ROC values of the urban growth probability index (UGPI) maps by the FR and LR models were 0.937 and 0.940, respectively. The LR map had a slightly higher ROC value than the FR map, but the numerical difference was slight, with both models showing similar results. The FR model is the simplest tool for probability analysis of urban growth, providing a faster and easier calculation process than other available tools. Additionally, the results can be easily interpreted. In contrast, for the LR model, only a limited amount of input data can be processed by the statistical program and a separate conversion process for input and output data is necessary. In conclusion, although the FR model is the simplest way to analyze the probability of urban growth, the LR model is more appropriate because it allows for quantitative analysis.

Objectives: This study aims to investigate the AD (allergic diseases: asthma, allergic rhinitis and atopic dermatitis) prevalence among elementary schoolchildren in an industrial city, Ulsan, and identify major environmental risk factors associated with AD prevalence. Methods: Data on the physician-diagnosed prevalence over the past 12 months and potential risk factors of AD were collected through a questionnaire from a 2009-2010 survey of 4,067 schoolchildren living in different urban environments. The logistic regression analysis was performed to assess differences in AD prevalence among the areas and to determine which environmental factors impacted AD. Results: Our survey results showed that the AD prevalence rate ranged between 26.2% and 35.9%. Children living in polluted areas (near industrial and central urban areas) had about a 10% higher prevalence of AD than did those living in coastal or suburban residences. The Chi-Square test demonstrated that this local difference was statistically significant before and after adjustment of major confounders such as parental AD history and parental education. The results of the logistic regression analysis showed a statistically significant association between several environmental factors (ventilation in winter, odor conditions and exposure to traffic smoke, and outdoor $PM_{10}/O_3$ pollution) and the prevalence of AD found by multivariate model after adjusting confounders. Conclusion: These results suggest that local differences in AD prevalence are significantly associated with outdoor environmental factors. Although there are likely to be other risk factors for AD, living in a polluted area and exposure to high levels of air pollutants can contribute to an increased risk of childhood AD.

Purpose: This study aimed to explore the association of ${\beta}-catenin$ expression pattern with pathological response after neoadjuvant chemotherapy in breast cancer (BC) patients. Materials and Methods: In this retrospective exploratory study, data for 50 BC patients who received neoadjuvant chemotherapy were recorded. ${\beta}-catenin$ expression in tumours was assessed using immunohistochemistry and classified as either membranous or cytoplasmic according to the pattern of staining. Distributions of different clinico-pathological parameters according to ${\beta}-catenin$ expression were assessed using the Chi-square test. Logistic regression analysis was used to assess any relation of the pattern of ${\beta}-catenin$ expression with the pathological response. Results: Cytoplasmic ${\beta}-catenin$ expression was detected in 34% of BCs. Among our cases, 52% were hormonal receptor (HR)-positive, 24% were HER2-positive, 74% were clinical stage III and 74% received both anthracycline and taxane-based chemotherapy. Patients with cytoplasmic expression were more commonly younger than 40 years at diagnosis (cytoplasmic, 41.2% vs. no cytoplasmic expression, 12.1%, p=0.03). By doing t-test, cytoplasmic ${\beta}-catenin$ expression was linked with a higher body mass index compared to membranous-only expression ($mean{\pm}SD$ $33.0{\pm}4.47$ vs. $29.6{\pm}6.01$, respectively, p=0.046). No significant associations were found between ${\beta}-catenin$ expression and other parameters such as HR and HER2 status, or clinical stage. Complete pathological response (pCR) rate was twice as great in patients with membranous expression but without statistical significance (membranous-only, 33.3% vs. cytoplasmic, 17.6%, OR= 2.3, 95% CI= 0.55-9.87, p=0.24). Conclusions: This study suggests that cytoplasmic ${\beta}-catenin$ expression may be linked with lower probability of achieving pCR after neoadjuvant chemotherapy. These data need to be validated in a larger cohort of patients.

Background: During and after the Fukushima nuclear disaster (FND), many parents were concerned about the effects of radiation on the health of their children. Purpose: To clarify the factors that influenced general workers living with children and the effect of child age groups in implementing preventive behaviorsagainst radiation following the FND. Materials and Methods: A descriptive study of preventive behaviors among general workers was carried out 3-5 months after the nuclear disaster. The subjects were 1,394 regular workers, who took part in radiation seminars run by the Fukushima Occupational Health Promotion Center between July and September, 2011. In total, 1,217 responses were submitted, of which 1,110 were eligible for the present study. This anonymous questionnaire survey inquired about the presence and age of children in the household and about radiation preventive behavior implemented after the FND. The contribution of each variable was assessed by logistic regression analysis. Results: General workers in Fukushima who lived with younger children performed more preventive behavior against radiation during and after the FND. In particular, both location-related and daily routines were practiced significantly more frequently (p<0.01) by workers living with a child in the age ranges of 0-6 (8 of 10 items) and 7-12 (5 of 10 items). Conclusions: This is the first study to assess the positive association between living with children by age group and increased preventive behavior against radiation implemented by general workers after the FND.
