This study examined the patterns of coping strategies among Koreans during the early stage of the COVID-19 pandemic, explored the influence of demographic information (gender, age, economic level, household type), along with the unusual experiences due to COVID-19 (fear, stress of COVID, constraints of routine, income risk) on the classification of subclasses, and analyzed the latent profile differences in psychological wellbeing (life satisfaction, depression, and anxiety). An online survey was conducted among Korean Adults(n=600) between April 13, 2020 and 21, when WHO declared COVID-19 a global pandemic and Daegu as well as Gyeongsangbuk-do was nominated as a special disaster zone. First, Latent Profile Analysis (LPA) was used to identify subclasses of coping strategies and results suggested that the 4-class model had the best fit. Second, Class memberships were predicted by gender, age, economic level, as well as fear, stress, constraints of routine, and income risk, among the unusual experiences due to COVID-19. Finally, there are differences in psychological wellbeing among latent profiles. 'High level of adaptive coping group 3' showed the highest level of life satisfaction, 'Adaptive-maladaptive coping group 4' showed the highest level of depression, anxiety. Implications and suggestions are discussed based on the study results.

This study was conducted to understand the emotional and situational context where non-suicidal self-injury occurs in everyday life. Sixty adults(age 19-35) completed daily surveys assessing positive and negative emotions, stressful events, self-injury thoughts, and behaviors for two weeks. Using a total of 663 collected entries, we analyzed specific personal emotions and stressful events related to non-suicidal self-injurious thoughts and behaviors. As a result, high negative emotions, low positive emotions, and total stress event scores were significantly related to self-injury thoughts and behaviors. In the model in which both emotion and stress were inserted as predictors, the low level of positive emotion showed a significant related to non-suicidal self-injurious behavior. These results suggest that negative emotion management and overall positive emotion reinforcement are important in emotion regulation intervention for non-suicidal self-injurious patients. The meaning of this study is that it searched for risk factors of non-suicidal injury in everyday life using a short-term longitudinal method.

The purpose of this study was to investigate the effects of the MICE industrial employee's job stressors on intent to leave and test of the mediating role of job satisfaction and job commitment. For the study, job stressors were defined 3 groups with 7 sub-factors, such as role stressors of role ambiguity, role conflict and role overload, task stressors of job routineness and job heteronomy, organizational stressors of job insecurity and distributive injustice. Data were collected from 303 MICE industrial employees in metropolitan area by structured questionnaires. Collected data were analyzed by AMOS 18.0 and findings are as follows. Firstly, on aspect of total effectiveness, the seven job stressors had harmful effect on intent to leave, especially organizational stressors had more serious effect on intent to leave than role stressors. Secondly, not only job satisfaction and job commitment had meditators role but also influenced on intent to leave directly. Thirdly, role ambiguity had effect on intent to leave indirectly through the job satisfaction, while role conflict and role overload had effect on intent to leave directly, and also indirect effectiveness on it through the job commitment. Fourthly, job routineness and job heteronomy had effected on intent to leave only through the meditators. Not only job insecurity and distributive injustice had influenced on intent to leave directly but also effectiveness on it indirectly through the meditators.

This study aimed to examine the model to explain the mediator effect of care evaluation(care stress, care satisfaction) on the effect of stress factors and resource on the psychological well-being of the parents of the adult intellectual disabilities. Examining whether there is a difference between the gender of parents was another aim of this study. Study results showed that with the care stress as an endogenous variable, the daily life function and maladjustment behavior of adult children and the health state of parents had a significant direct effect on the psychological well-being of parents. With care satisfaction as an endogenous variable, family support, expert support and care stress had a significant direct effect. With the psychological well-being as an endogenous variable, care satisfaction and care stress had a significant effect, but the health state of parents didn't. In case of indirect effect, the care stress had a significant mediator effect on the effect of the physical function and maladjustment behavior of adult children and the health state of parents on the psychological well-being of parents. Care satisfaction had a significant mediator effect on the effect of family support, expert support and care stress on the psychological well-being of parents. According to the result of the Multiple Group Analysis, the path showed a statistically significant difference between gender was friend support→care satisfaction, care stress→psychological wellbeing, expert support→care satisfaction. On the basis of the study results, practical suggestions were made.

The purpose of this study was to investigate the prevalence of depression and related to the factors among the rural people. The questionnaire survey using the Center for Epidemiology Studies-Depression Scale(CES-D) was conducted in the rural people. The subjects were 226 individuals, living in the rural area. The results of this study were as follows. In this study, the prevalence of depression was 15.0% in all and 18.3% in the elderly. The prevalence rate was higher in non educational, widowhood, higher income group. The prevalence rate was lower in the group of having good health status, having no chronic disease, low stress level. In the multiple logistic regression analysis, significant predictors of the depression were stress level whereas there was no relation with other factors. Based on the above findings, this study suggests that these risk factors of depression should be taken into consideration for the comprehensive mental health programs for the people living in the rural area.

If one can infer the residential area of SNS users by analyzing the SNS big data, it can be an alternative by replacing the spatial big data researches which result from the location sparsity and ecological error. In this study, we developed the way of utilizing the daily life activity pattern, which can be found from timeline data of tweet users, to infer the residential areas of tweet users. We recognized the daily life activity pattern of tweet users from user's movement pattern and the regional cognition words that users text in tweet. The models based on user's movement and text are named as the daily movement pattern model and the daily activity field model, respectively. And then we selected the variables which are going to be utilized in each model. We defined the dependent variables as 0, if the residential areas that users tweet mainly are their home location(HL) and as 1, vice versa. According to our results, performed by the discriminant analysis, the hit ratio of the two models was 67.5%, 57.5% respectively. We tested both models by using the timeline data of the stress-related tweets. As a result, we inferred the residential areas of 5,301 users out of 48,235 users and could obtain 9,606 stress-related tweets with residential area. The results shows about 44 times increase by comparing to the geo-tagged tweets counts. We think that the methodology we have used in this study can be used not only to secure more location data in the study of SNS big data, but also to link the SNS big data with regional statistics in order to analyze the regional phenomenon.

Ecological momentary assessment (EMA) is a method that captures the current experience and behavior of subjects in real time in a natural environment. The data collected by EMA reveals alterations according to the time and context of experience and action. The Trier Inventory for Chronic Stress (TICS) is a tool that measures momentary stress, and is capable of measuring stress experienced in real life. This study was undertaken to verify the validity and reliability after translating the short form TICS into a Korean version. Totally, 89 police officers working at the police station in the capital participated in this study. The mobile application developed for this study was installed on their smartphones, and data were collected four times a day for seven consecutive days. Confirmatory factor analysis and content validity index (CVI) was applied to test the validity, and concurrent validity was evaluated by correlating with the occupational stress score. The model was validated by confirmatory factor analysis, and we obtained good reliabilities (I-CVI=0.83-1, RMSEA=0.104, SRMR=0.104, CFI=0.948, TLI=0.919, Cronbach's alpha=0.839). Our findings indicate the reliability, and validate use of the Korean tool for measuring momentary stress.
