This summary of literature during the past year reviews published studies relating to risk factors for depressive disorders in children and adolescents. Risk factors include environmental toxins, socio-environmental, and genetic factors. As depression has a complex, multifactorial causal mechanism, it is likely that the accumulation and/ or interaction among multiple risk factors lead to depression. Findings related to the result of toxin exposure have been difficult to interpret given that risk factors tend to interact and that higher mental functions are not easily measurable. However, some findings have been consistent. Clinical research data has also shown that the risk for negative outcomes may be modified both by genetic and environmental factors through a gene environment interplay mechanism.

This study aims to empirically examine the relationship between building energy consumption and building and local factors in Seoul. Building energy issue is an important topic for low carbon and eco-friendly city development. Building physical, socio-economic and environmental factors effect to increasing or decreasing energy consumption. However, there are different characteristic in each area, and this kind of variable has a hierarchical structure. The multi-level model was used to consider the hierarchical structure of the variables. In this study, a multi-level model was applied to confirm the difference between areas. Spatial area is Seoul, Korea and the temporal scope is August, summer season. As the result, in Model 1 (Null Model), ICC is 0.817. This shows that the energy consumption differs by 8.174% due to factors at the Dong level. Model 2 (Random Intercept Model) suggests that building's physical factors and Average age, Household size and Land price in Dong level have significant effects on Building energy consumption. In Model 3 (Random Coefficient Model), random effect variables have intercepts and slopes to vary across groups. This study provides a perspective for policy makers that the building energy reduction policies to be applied for buildings should be differently applied on area. Furthermore, not only physical factors but also socio-economic and environmental factors are important when making energy reduction policy.

This study aims to analyze the aquaculture farmers awareness of aquafarm management system influenced by socio-economic, environmental, and other factors using ordered logit model focused on aquafarm resting system. The survey data were obtained from 94 aquaculture farmers in Gyeongsangnamdo and Jeollanamdo province as a cross sectional data in 2015. This paper estimates the impact of socio-economic, environmental, and other characteristics, such as region, working period, productivity, environmental condition of fishing field, expected effectiveness of the system, and subject of responsibility on fishing field management. Based on the result, lastly, it suggests some implications to promote aquaculture farmers perception and participation in aquafarm resting system. The main results are as follows; the aquaculture farmers consciousness of the system is not affected by working period, productivity, and environmental condition of fishing field. But it is influenced by region, expected effectiveness of the system, and subject of responsibility on fishing field management. While it has a positive relationship with expected effectiveness of the system, it has a negative relationship with object who has responsibility on fishing field management.

It is important to understand what affects community satisfaction. Because community impacts and participation is a central aspect of fostering local community development, it is important to understand how these processes occur. The study aims to identify the factors influencing community satisfaction and to examine the moderating effects of community participation between community perceived impacts and community satisfaction. Data were collected from 328 usable questionnaires among community residents participating rural development projects in Buyeo and Chungyang county, Chungnam province. Results of a factor analysis yielded four dimensions of community perceived impacts which were negative socio-economic impacts, positive economic impacts, positive environmental impacts, and positive social impacts. Hierarchical regression analysis revealed that negative socio-economic impacts, positive economic impacts, and positive environmental impacts affected significantly for community satisfaction. it reveals that there are moderating effects on community participation of negative socio-economic impacts and positive economic impacts. It was suggested that negative socio-economic impacts, positive economic impacts, and community participation should be considered to implement rural development projects and its policy decision making.

This study estimates future AADT using historical AADT and socio-economic factors in isolated area. Multiple linear regression method by socio-economic factors are lower MAPE and higher R-square than using historical AADT. Analysis of socio-economic factors influence AADT in isolated typical areas, varied socio-economic factors influence on AADT. In isolated coastal areas, oil price influence on AADT. AADT forecasting model in isolated area is excellent when analysising $R^2$ and MAPE. It is assume that estimation of AADT in isolated area using multiple linear regression is accurate because of a little passed traffic volume and traffic volume fluctuation.

This study was conducted to empirically analyze the effect of life behavior and socio-environmental satisfaction on life satisfaction of the elderly with or without hearing loss. To this end, 3,071 elderly people of 「the Survey on the Actual Condition of the Elderly」 in 2020 were set as the subjects. After controlling for their demographic variables, the multiple regression model showed that the elderly with hearing loss had different factors of life behavior and socio-environment satisfaction that affected their life satisfaction compared to those without. As a result, the sub-factors of life behavior in the elderly with hearing loss, such as economic activities, social group activities, the use of the center, and the sub-factors of social environment satisfaction, such as family satisfaction and environmental satisfaction, had a positive (+) effect on life satisfaction. Especially, the elderly with hearing loss had more limitations in both the area of living behavior and the area of social environment satisfaction than the elderly without hearing loss. Therefore, in order to improve the life satisfaction of the elderly with hearing loss, it is suggested that the government and local governments should simultaneously supplement welfare policies and facilities for the elderly with hearing loss.

This study was performed to investigate the negative side effects of video display terminal (VDT) work on the human body and to provide data for preventing VDT syndrome. A questionnaire survey was made to 339 VDT workers at 22 offices in Taegu, Kyungpook and Kyungnam areas from July 1 to August 31, 1994, and 280 of them were finally used for statistical analysis. The VDT syndrome in the present study inclhded five factors, namely as eye-related symptom, psychological symptom, general body symptom, musculoskeletal symptom, and skin-related symptom, and the estimates of Crombach coefficients of the five factors were 0.954, 0.952, 0.953, 0.957, and 0.955, respectively, showing very high reliability. In view of socio-economical characteristics, the symptoms of female were higher than those of male in the order of musculoskeletal symptom, eye-related symptom, skin-related symptom and psychological symptom. The age group of 30 years or less was higher than the older groups in the order of musculoskeletal symptom, eye-related symptom, psychological symptom and skinrelated symptom. The group of lower education level showed higher skin-related symptom. The psychological symptom and skin-related symptom increased as the amount of smoking increased. Higher eye-related symptom was observed in the group without glasses. In the job-related variables, the group of working on programming and data input showed higher eye-related symptom and psychological symptom. The group of working on programming and graphic design showed higher musculoskeletal symptom and skin-related symptom. The skin-related symptom increased as the total time of VDT operation per day increased. The group of working 2-4 hours followed by 15 minutes rest was higher in musculoskeletal symptom and psychological symptom. Higher musculoskeletal symptom was observed from the group working on Friday and Sunday. The group of 1 year or less working showed higher in skin-related symptom. In relation with the VDT type, all symptoms except skin-related symptom were higher in the group using monochrome monitor. As showed above, the questionnaire could be a tool for evaluating VDT syndrome and prevention of the syndrome would be possible by a comprehensive consideration of factors including socio-economic characteristics, job-related variables and VDT type.

The grassland regions of Australia, the Pacific and Asia share common latitudes albeit in opposing hemispheres. However, the environmental and socio-cultural context of pasture development in the subtropical and tropical regions of Australia, the Pacific Islands and Asia differ greatly. Successful technology transfer for improved productivity of grazing livestock is beset by three broad challenges; technical, logistical and socio-cultural. The technical challenge of defining the grassland environment and adapting known technology to local conditions can be successfully addressed by local technicians supported by a reservoir of appropriate international expertise. Logistical difficulties that impede provision of infrastructure and continuity of support services are the responsibility of indigenous organizations. Socio-cultural factors are fundamentally pervasive. These challenges, though outwardly obvious, require careful consideration by both donors and recipients of pasture technology to ensure success with pasture development for viable grazing industries.
