Purpose: This study aims to test the validity and criteria-related reliability of the Korean version of the Copenhagen Psyco-social Questionnaire version II (COPSOQ-K) assessing the psychosocial working environment. Methods: The COPSOQ-K was developed through forward-backward translation techniques, and revision based on feedback from focus groups. Survey data were collected from 311 office workers who worked in one workplace. An internal consistency reliability was estimated by Cronbach's ${\alpha}$. The impacts of the COPSOQ-K scales on job satisfaction, self-rated health, stress, sleeping troubles, burnout, and sickness absence were analyzed with multiple regression model or multiple logistic regression model, adjusted age and gender using SAS version 9.3. The Pearson correlation coefficients between the COPSOQ-K scales and Korean job stress and its subdomain were identified. Results: Cronbach's ${\alpha}$ of COPSOQ-K scales was adequate or good (0.66~0.87). The major COPSOQ-K scales predict job satisfaction, self-rated health, stress, sleeping troubles burnout, and sickness absence. The major COPSOQ-K scales were correlated with Korean job stress and its subdomain. Conclusion: The COPSOQ-K scales have satisfactory reliability and criteria-related validity. The COPSOQ-K scales will be useful for the future studies and practices associated with psychosocial working environment.

Objectives: Quality of Working Life(QWL) is a set of employee's physical, mental conditions which are perceived at their work. Most employees and managers are concerned about the quality of working life as a strategy for improving organizational effectiveness. The purpose of this study is to investigate the relationship between QWL and organizational effectiveness of employees at the general hospital. Methods : Data were collected by self-administered questionnaires at the general hospital in Kyunggi-Do. Survey was conducted to 675 workers. QWL was measured by using 5 items from the scale developed by Walton(1973). Organizational effectiveness was measured by measuring organizational commitment, intention of job-shift, and job satisfaction. Results: The recognitions to each component of QWL were significantly different by socio-demographic characteristics such as sex, age, education levels and working duration. Also, QWL were significantly different by types of organizational culture. Multiple regression analysis and multiple logistic regression analysis were applied to find the relationship of QWL and organizational effectiveness. As a result, job-pride, compensation, working condition, human relationship and development showed significant relationship with organizational effectiveness. Conclusions: These results show that QWL is significantly related to organizational effectiveness. So we expect that this result will be used as basic informations for management and motivation of employees at the general hospital.

Objectives: The purpose of this study was to examine the relationship between stress and halitosis in a representative sample of Korean adolescents. Methods: This study was based on the 15th Korea Youth Risk Behavior Survey (2019). The final participation rate in the survey was 95.3%; 57,303 out of 60,100 (95.3%) adolescents aged 13-18 years were selected. Multiple logistic regression with complex samples was performed to identify the correlation between stress and halitosis. Stress level was classified as 'very much', 'a little', and 'not much' and halitosis was defined as the presence of an unpleasant odor in the oral cavity. Results: The prevalence of halitosis among students was 21.3%. As a result of multiple regression analysis, the 'a little' [odds ratio (OR); 1.39, 95% confidence interval (CI); 1.29-1.49] and 'very much' stress group (OR; 1.78, 95% CI; 1.66-1.90) exhibited significantly higher risk of halitosis than the 'not much' stress group. Conclusions: A significant correlation between stress and halitosis exists among Korean adolescents. Therefore, psychological factors such as stress should be considered in managing halitosis in adolescents.

The information of covariates are available to do fully efficient fractional imputation(FEFI). The new method, FEFI with logistic regression is proposed to construct complete contingency tables. Jackknife method is used to get a standard errors of log-odds ratio from the completed table by the new method. Simulation results, when covariates have more information about categorical variables, reveal that the new method provides more efficient estimates of log-odds ratio than either multiple imputation(MI) based on data augmentation or complete case analysis.

We investigate the latent stage-sequential patterns of drinking behaviors of U.S. adolescents who have started to drink by age 14 years (seven years before the legal drinking age). A multiple-group latent transition analysis(LTA) with logistic regression is employed to identify the subsequent patterns of drinking behaviors among early-onset drinkers. A sample of 1407 early-onset adolescents from the National Longitudinal Survey of Youth(NLSY97) is analyzed using maximum-likelihood estimation. The analysis demonstrates that early-onset adolescents' drinking behaviors can be represented by four latent classes and their prevalence and transition are influenced by demographic factors of gender, age, and race.

Purpose - The purpose of this paper is to find out a range of cues that trigger employees to willingly make efforts for corporate development in small and medium enterprises. This was determined by assessing the effects of employees' value inclination on their job satisfaction and organizational citizenship behavior as well as how they perceived their organizational support. Research design, data, and methodology - A total of 126 valid questionnaire sheets collected from SME employees were analyzed with SPSS 24.0 and AMOS 24.0 involving simple regression analysis, multiple regression analysis, hierarchical moderated regression analysis and 3-step mediated regression analysis. Results - The analyses highlighted employees' personal value inclination had positive effects on their job satisfaction, which in turn enhanced their organizational citizenship behavior. Meanwhile, individualist and collectivist inclination exerted greater effects on job satisfaction and organizational citizenship behavior, respectively. The study also revealed that perceived organizational support moderated the relationship between job satisfaction and organizational citizenship behavior. Conclusion - Hence, CEOs in SMEs should avert any dichotomous analysis of their employees' value inclination, respect their personal value inclinations and also apply factors that could raise their job satisfaction. Likewise, it was shown that SME employees need to make personal efforts for organizational development.

Purpose: The aim of the study was to evaluate the correlation of ultrasound features with breast cancer molecular status. Materials and Methods: A retrospective review was performed of ultrasound findings in 263 patients diagnosed with breast invasive ductal carcinoma for comparison with immunohistochemistric results were obtained from each lesion. Relationships between ultrasound findings and molecular status were investigated by using multiple regression analysis by means of stepwise logistic regression. Differences in ultrasound criteria were assessed among women with different molecular status. Results: ER positivity was associated with small size, lobulate, angular or spiculated margin contours, absence of calcification, posterior tumor shadowing and low elasticity score; PR positivity was associated with small size, lobulate or angular or spiculated margin contours and absence of calcification; HER2 positivity was associated with presence of calcification and absence of any echogenic halo. The calculated models of predicted molecular status were accurate and discriminating with AUCs of 0.78, 0.74, and 0.74, respectively. Conclusions: Breast cnacer ultrasound features show some correlation with the molecular status. These models may help to expand the scope of ultrasound in predicting tumor biology.

Purpose: The purpose of this study was to compare and contrast health promoting behaviors, mental health, and quality of life between shift nurses and non-shift nurses and to evaluate factors influencing their quality of life. Method: Data were collected by questionnaires from 113 non-shift nurses and 265 shift nurses who had been working at one of five hospitals in Incheon for more than one year. Descriptive statistics, ANCOVA, logistic regression, and multiple regression were used in performance of data analysis. Results: For shift nurses' mean total scores for health promoting behaviors and quality of life were significantly lower than those for non-shift nurses'(p<.05). Result of logistic regression analyses indicated that marital status (OR=2.092, 95%CI=1.174-3.729) and quality of life (OR=3.397, 95%CI=1.694-6.812) were significant between shift nurses and non-shift nurses. Non-shift work, low stress, provision of health-welfare programs, high score for health promoting behavior, and good mental health status showed an association with better quality of life (explained 48.3% of variance). Conclusion: Educational, policy, and regulatory approaches are required in order to improve mental health and quality of life for nurses, which may be influenced by their unhealthy behaviors such as irregular dietary patterns, while provision of counseling programs may be helpful to enhancement of nurses' mental health.

Objectives: Cigarette smoking prevalence among adolescent males in rural areas of Korea has increased in recent years. The aim of this study was to explore the factors related to increasing trends in cigarette smoking among adolescent males living in rural areas. Methods: The raw data from the Korea Youth Risk Behavior Web-based Survey from 2006 to 2009 were used. Data were analyzed by using the method of complex survey data analysis considering complex sampling design. Multiple logistic regression models were used to explore the factors affecting cigarette smoking. We evaluated the linear time trends in the prevalence of factors that were related to current smoking status and the linear time trends in cigarette smoking in groups stratified by the exposure to each factor using logistic regression models. Finally, we examined the contributions of the factors to the time trends in cigarette smoking by adjusting for each of those factors in the baseline regression models and changes in the adjusted odds ratio by survey year. Results: A statistically significant increasing trend in smoking was observed after adjusting for the factors affecting cigarette smoking. Significant factors related to cigarette use were perceived stress, experience with depression, current alcohol drinking, exposure to secondhand smoke, and academic performance. The factor related to increasing trends in cigarette smoking was academic performance. Conclusions: Stress about academic performance is an important factor affecting the increase in cigarette smoking among adolescent males in a rural area of Korea.
