The purpose of this study is to develop the School Multicultural Climate(SMC) scale for students and to evaluate its reliability and validity. This study comprises of both qualitative and quantitative research. Preliminary items were developed based on the theoretical literature and interviews with students. The scale was evaluated with students in grades 4 through 6 in the seven elementary schools. Exploratory factor analysis was determined that the scale was composed of four components: Equal Status, Mutual Cooperation, Friendly Relations, Supportive Norms. The scale demonstrated that Cronbach's alpha=.943 for the internal consistency of total items. And the standard error of the measurement, another way of evaluating reliability, was 3.33. Criteria-related validity was evaluated by showing that the differences of the students' recognition of the school multicultural climate level, which depend on the availability of the multiculture-related policy, was statistically significant. The correlation analysis for the convergent validity was performed with the theoretically related variables such as self esteem and school adjustment. It was found that the SMC scale was a reliable and valid measure for evaluating the multicultural climate level of elementary school.

This study was conducted to review the literature and examine the factors related to problem behaviors among students of multicultural families in Korea. A systematic review of the literature was conducted using domestic documents retrieved through July 4, 2018 based on online searches of domestic databases (the Research Information Sharing Service, Korean Studies Information Service System and the National Diet Library). A total of 2,084 studies were searched, and 21 studies were used for analysis. The factors related to problem behaviors were related to individual factors (gender, school record, self-esteem, etc.), family factors (family type, parent support, mothers' enculturation stress, etc.) and environmental factors (friend support, teacher support, social support). The variables measured the problem behaviors among students of multicultural families were school life adjustment (10), psychological, social adjustment or maladjustment (4), and emotional problem behavior (3). Overall, the results indicate that social and policy efforts are needed to improve individual, family, and environmental factors based on more specific and consistent theoretical definitions related to problem behaviors among students of multicultural families in Korea.

Objectives: The purpose of this study is to evaluate the influence of depression symptom on the self-rated health status(SRHS), the outpatient health service utilization and quality of life(QOL) also the relationship depression symptom with socio-demographic and health related factors. Methods: We selected 9,550 participants without chronic diseases from a total of 18,104 in the '2009 community health survey in Gyeongnam. They were assessed by using a Korean version of the Center for Epidemiological Studies-Depression Scale(CES-D). Those with CES-D scores of 21 or greater were defined as having probable depression. Results: A probable depression were associated in bivariate analysis with gender, age, educational status, monthly household income, marital status, current smoking status, drinking habit, physical activities and body mass index. After adjustment for covariates, probable depression groups predicted a lower status in SRHS. Likewise probable depression groups predicted a higher utilization in outpatient health service. Also probable depression groups predicted a lower score in QOL. Conclusions: Probable depression influence SRHS, outpatient health service utilization and QOL even after adjusting for the socio-demographic, health related factors and chronic medical illness. Programs for prevention and management of depression will be helpful to promote health and QOL.

The purpose of this study is to understand the school achievement of domestic adopted children in Korea and its related factors. Although the developmental outcomes of domestic adopted children were the focus of research interests, their school achievement has never been fully addressed in Korea. The subsample (9-17 years old) of 5th wave data of was used for the analysis. The results showed that the school achievement level of domestic adopted children was not significantly different from their non-adopted peers during elementary school years except the mathematics, but changed drastically after they entered the middle school, showing significantly lower level from their non-adopted peers. Factors related with the overall school achievement were the level of school, maternal education, age at adoption, child's self-esteem and school adjustment. For specific subject, however, significant factors were found to be somewhat different. Based on the results of the study, the practical guidelines to improve the school achievement of adopted children were suggested. Also, suggestions for the following studies were made.

Background: Lower-limb varicose veins (VVs) are common and known to have a higher prevalence among people who work in occupations requiring prolonged standing. In the Republic of Korea, however, VV-related occupational factors have seldom been examined. This study was conducted to assess the prevalence of VVs among nurses, an occupational group considered to be at high risk of VVs, and determine the occupational risk factors of prolonged standing. Methods: Between March and August 2014, a questionnaire survey coupled with Doppler ultrasonography was conducted on the nurses working at a university hospital. Results: A total of 414 nurses participated in the survey and diagnostic testing. From the survey analysis and test results, the prevalence of VVs in nurses was estimated to be 16.18%. Significant factors for venous reflux were age [odds ratio (OR) = 1.06, 95% confidence interval (CI) = 1.03-1.10], pregnancy (OR = 2.15, 95% CI = 1.17-3.94), and delivery (OR = 2.02, 95% CI = 1.08-3.78). The statistical significance of these factors was verified after risk adjustment for sociodemographic factors (OR = 3.40, 95% CI = 1.27-9.09). Conclusion: Factors significantly associated with venous reflux were increasing age and prolonged working hours (${\geq}4hours$) in a standing position (OR = 2.80, 95% CI = 1.08-7.25), even after risk adjustment for sociodemographic factors. This study is significant in that an objective diagnosis of VVs preceded the analysis of the risk factors for VV incidence, thus verifying objectively that VVs are associated with occupations requiring prolonged hours of working in a standing position.

Purpose: This study explored the influencing factors on suicide-related behaviors (ideation, plans, and attempts) focusing on mental health problems (anxiety, depression, and loneliness) among Korean adolescents. Methods: A secondary analysis was conducted with data from the 16th Korean Youth Health Behavior Survey collected from in 2020 by the Korea Centers for Disease Control and Prevention. Chi-square tests and multivariate logistic regression analyses were performed. Results: After the adjustment of demographic characteristics and health risk behaviors, the influences of mental health problems on suicidal ideation, plans, and attempts showed the anxiety odds ratio (OR) for severe anxiety vs. minimal (OR 4.65, 4.67, and 3.75), depression (OR 4.27, 3.69, and 4.49), loneliness (OR 2.18, 1.96, and 1.96). Health risk behaviors (violence experience, drug use, stress, smoking, and drinking alcohol) and demographic variables (gender, school record, and socioeconomic status) were also significantly associated with suicide-related behaviors. Conclusion: Anxiety, depression, and loneliness were strong predictors of suicide-related behaviors. Early detection of suicide risks through screening for comprehensive mental health problems was recommended. Suicide prevention that considers the risk factors, including mental health problems and other risk factors, needs to be developed and implemented to reduce suicide risks among adolescents.

Objectives: With increasing concerns for the rapidly growing minority population in South Korea, this literature review addressed a range of mental health risks among multiethnic youths (MY) in South Korea by 1) comparing mental health outcomes with those of native-born youths and 2) identifying multiple layers of relevant environmental factors, from family and school relationships to culture. Methods: We reviewed 54 studies that fulfilled specific inclusion criteria. Results: Multiple common risk/protective factors, including family separation, family relationship quality, parental socioeconomic and mental health status, social relationships at school, and cultural acceptance, were noted. Conclusion: In general, empirical evidence indicates that minority youths have relatively heightened risks for emotional and behavioral problems. Future studies must elucidate the complex interplay between multiple risk and protective factors and the long-term adaptation and mental health service utilization of MY.

A grid-connected 3-level NPC inverter is a power conversion device that connects renewable energy generators, such as photovoltaic or wind turbines to the grid. Although many studies have focused on this inverter, commercializing it requires strictly satisfying various safety and power quality-related standards. Among many standards, leakage current and grid current total harmonic distortion(THD) can be affected by external factors such as installation environment, aging, and grid conditions. Hence, inverter operations that can satisfy these standards need to be explored. In this study a 3-level NPC inverter operation algorithm using the Phase Opposition Disposition-PWM method that can effectively reduce leakage current and switching frequency adjustment to reduce THD effectively has been proposed.

Objectives: People who have chronic diseases, as well as gait imbalance or psychiatric drug use, may be susceptible to injuries from falls and slips. The purpose of this study was to evaluate the effect of musculoskeletal diseases on incidental fall-related injuries among adults in Korea. Methods: We analyzed data from the 4th Korea National Health and Nutrition Examination Survey (2007-2009), which are national data obtained by a rolling survey sampling method. The 1-year incidence of fall-related injuries was defined by health service utilization within the last year due to injury occurring after a slip and fall, and musculoskeletal diseases included osteoarthritis, rheumatoid arthritis, osteoporosis, and back pain. To evaluate the effects of preexisting musculoskeletal diseases, adults diagnosed before the last year were considered the exposed group, and adults who had never been diagnosed were the unexposed group. Results: The weighted lifetime prevalence of musculoskeletal disease was 32 540 per 100 000 persons. Musculoskeletal diseases were associated with a higher risk of fall-related injury after adjustment for sex, age, residence, household income, education, occupation, visual disturbance, paralysis due to stroke, and medication for depression (odds ratio [OR], 1.41; 95% confidence interval [CI], 1.03 to 1.93). As the number of comorbid musculoskeletal diseases increased, the risk of fall-induced injuries increased (p-value for trend <0.001). In particular, patients who had any musculoskeletal condition were at much higher risk of recurrent fall-related injuries (OR, 6.20; 95% CI, 1.06 to 36.08). Conclusions: One must take into account the risk of fall-related injuries and provide prevention strategies among adults who have musculoskeletal diseases.

Purpose: The purpose of this study was to investigate factors affecting the experience of depression in school-aged children from multicultural families. Methods: Data from 1,812 school-aged children of multicultural families were collected from the 2015 National Multicultural Family Survey. Logistic regression was conducted based on complex sample analysis using SAS 9.4. Results: Significant predictors for experiencing depression were lower self-esteem, lower Korean proficiency, less time spent conversing with the father, lower degree of parental interest, poorer school adjustment, greater difficulties with schoolwork, and experiencing violence at school. Conclusion: This study showed that factors related to the individual, family, and school environment influenced the experience of depression. Based on a consideration of these factors, it is necessary to develop an effective program to prevent depression by establishing high-risk criteria for depression.
