The purpose of this study was to investigate depression and school adjustment of institutionalized children and adolescents according to their ego-identity, gender, grade(age), relationship with parents before entering the institution, cause of entering the institution, duration of entering the institution, parents'visiting, psychological environment of institution. The subjects were 121 5th and 6th graders(59 boys and 62 girls), 135 middle school (58 boys and 77 girls), and 85 high school students (44 boys and 41 girls), who were institutionalized in Seoul. The data were analyzed by t-test, one-way and two-way ANOVA, Scheffe'test, and multiple regression analysis. The major findings of this study were as follows: 1) Depression and school adjustment of institutionalized children and adolescents were different according to their ego-identity, relationship with parents before entering the institution and psychological environment of institution. And school adjustment of institutionalized children and adolescents were different according to grade(age). 2) In regression analysis models, ego-identity and cause of entering the institution were significant predictors of depression, and ego-identity more predicted to depression than cause of entering the institution. And ego-identity and age(grade) were significant predictors of school adjustment, and ego-identity predicted to school adjustment as well as grade(age).

This study is intended to look into the effects of depression and stress on college life adjustment of ophthalmic optics students. To achieve this, a survey was empirically carried out to 142 male and female students majoring in ophthalmic optics at colleges in Gangwon-do. The findings are as follows: Depression had a significant effect on academic adjustment and social adjustment, but no significant effect on emotional adjustment and college satisfaction. Stress also had a significant effect on academic adjustment, but no significant effect on social adjustment, emotional adjustment and college satisfaction. The above results showed that depression and stress were major factors affecting academic and social adjustments, and academic adjustment, respectively. Which means that depression restricted the activities of academic adjustment and social adjustment, and did not have a close relationship with psychological mechanisms - emotional adjustment and college life satisfaction. Stress also had a significant effect on academic adjustment, but did not have a direct relationship with social adjustment, emotional adjustment and college satisfaction.

The collaboration productively interacting between multi-agents has become an emerging issue in real-world applications. In reinforcement learning, multi-agent environments present challenges beyond tractable issues in single-agent settings. This collaborative environment has the following highly complex attributes: sparse rewards for task completion, limited communications between each other, and only partial observations. In particular, adjustments in an agent's action policy result in a nonstationary environment from the other agent's perspective, which causes high variance in the learned policies and prevents the direct use of reinforcement learning approaches. Unexpected social loafing caused by high dispersion makes it difficult for all agents to succeed in collaborative tasks. Therefore, we address a paradox caused by the social loafing to significantly reduce total returns after a certain timestep of multi-agent reinforcement learning. We further demonstrate that the collaborative paradox in multi-agent environments can be avoided by our proposed effective early stop method leveraging a metric for social loafing.

본 연구는 K 대학교에 재학 중인 학생 57명의 부모를 대상으로 자녀의 조기진급 및 조기졸업의 필요성과 대학생활 적응에 대한 부모지각을 다변량 분산분석(Multivariate Analysis of Variance)과 다변량 공분산분석(Multivariate Analysis of Covariance)을 실시하여 분석하였다. 연구 결과, 조기진급 및 조기졸업을 한 자녀를 룬 부모는 고등학교 3년 과정을 마치고 대학에 입학한 자녀를 둔 부모보다 '조기진급에 대한 정보'를 더 만이 알고 있었던 것으로 나타났다. 이에, 본 연구는 '조기진급에 대한 정보'를 공변량으로 통제한 후, 자녀의 적응에 대한 부모지각을 조사하였다. 그 결과, '조기 진급에 대한 정보'를 많이 가지고 있었던 부모는 자녀가 대학에 보다 잘 적응한다고 지각하였다. 그러나 '조기진급에 대한 정보'가 자녀의 적응에 대한 부모지각에 미치는 영향을 통제하였을 때, 조기진급 및 조기졸업 유무에 따른 부모지각에서 유의한 차이가 없었다. 따라서 조기진급 및 조기졸업에 대한 정보를 많이 가지고 있는 부모 일수록 이에 대한 필요성을 보다 신중하게 고려하며 의사결정에 임할 뿐 아니라, 대학에 입학한 자녀의 진로 및 학습 적응 그리고 대학 생활에서 자녀가 경험하는 사회정서적 적응에 대해서도 비교적 덜 우려하는 것으로 나타났다.

The purpose of this study was to analyze differences in psychological characteristics according to cell phone dependency and use purpose in cell phone users of adolescences. Psychological characteristics of adolescents were consisted of attention aggression, somatic symptoms, social withdrawal, depression variables. The subjects were 2,158 cell phone owned second graders of middle school. A data of the Korean Child-Youth Panel Survey(KCYPS) was employed for the this study. Dependency and use purpose of cell phone were classified by cluster analysis into four groups with similar characteristics : 'high dependency-multipurpose', 'low dependency-social', 'low dependency-unsocial' 'middle dependency-peer interaction' groups. Major findings were that: the group differences in psychological characteristics were statistically significant. The 'low dependency-social' group showed highest on adjustments, and the other groups were maladaptive. Finally, implications for future research were discussed.

Background: The present objective was to verify whether burnout (emotional exhaustion [EE], depersonalization [DP] and low professional efficacy [PE]) is a risk factor for long-term sickness absence (LTSA; 30 consecutive days) from the teaching role. Methods: This was a prospective cohort study with two years of follow-up that investigated 509 elementary and high-school teachers. Burnout was identified by Maslach Burnout Inventory. Poisson regression with robust variance was used to adjust for possible confounders. Results: The incidence of LTSA was 9.4%. High EE levels were associated with LTSA in the crude analysis, but the association lost statistical significance after adjustments (for sex, age, perception of work-life balance, general self-rated health, chronic pain and depression). High DP levels were associated with this outcome, even after all adjustments (relative risk = 1.80; 95% confidence interval: 1.05-3.09). Low PE levels were not related to LTSA. Conclusion: The results reinforce the need to improve teachers' work conditions to reduce burnout, particularly DP, and its consequences.

Objectives: This study was conducted to investigate the relationships between trust and participation in cancer screening. Methods: Data from 2004 Busan Health Survey were analysed for the study. Multiple logistic regression was performed on participation in cancer screening by trust level with potential confounders(sex, age, education, monthly mean household income, subjective health status, smoking, alcohol intake, exercise, and daily eating habits). Results: In a total of 7,423 participants, 2,078(28.0%) were classified as cancer screening participants. High horizontal trust was associated with increased likelihood of cancer screening participation(OR(men) = 1.20, 95% CI 1.00-1.45) and (OR(women) = 1.19, 95% CI 1.02-1.39), after multiple adjustments. Respondents with high trust in health care system had significantly higher odds ratios for participation in cancer screening: 1.60(95% CI 1.27-2.02) among men and 1.18(95% CI 0.97-1.44) among women, after multiple adjustments. Conclusions: Trust was significantly associated with higher odds of cancer screening participation and could be a potent arena for increasing cancer screening participation.

The gig economy offers many advantages, such as flexibility, variety, independence, and lower cost. However, there are also safety concerns, lack of regulations, uncertainty, and unsatisfactory services, causing people to voice their opinion on social media. This paper aims to explore the sentiments of consumers concerning gig economy services (Grab, Foodpanda and Airbnb) through the analysis of social media. First, Vader Lexicon was used to classify the comments into positive, negative, and neutral sentiments. Then, the comments were further classified into three machine learning algorithms: Support Vector Machine, Light Gradient Boosted Machine, and Logistic Regression. Results suggested that gig economy services in Malaysia received more positive sentiments (52%) than negative sentiments (19%) and neutral sentiments (29%). Based on the three algorithms used in this research, LGBM has been the best model with the highest accuracy of 85%, while SVM has 84% and LR 82%. The results of this study proved the power of text mining and sentiment analysis in extracting business value and providing insight to businesses. Additionally, it aids gig managers and service providers in understanding clients' sentiments about their goods and services and making necessary adjustments to optimize satisfaction.
