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 sought to identify developmental trajectories of bullying victimization from late elementary school through early high school, and to examine internalizing and externalizing problem outcomes associated with the trajectory group membership. Data from Seoul Panel Study of Children were collected annually over a 7-year period from 5th grade of elementary school through 2nd grade of high school (2005~2011). Latent class growth analysis yield three trajectory classes corresponding to stable low (81.2%), stable high (3.5%), and declining bullying victimization (15.6%). Findings from analysis of covariance indicated that students in both stable high and declining trajectory groups reported significantly higher means in internalizing behavior (withdrawal, depression/anxiety, and suicide ideation), compared to those in the stable low group. For externalizing behavior such as aggression and juvenile status offense, students in the stable high group showed higher means, compared to those in the stable low and declining trajectory groups. Developmental pattern of bullying victimization over multiple development stages and associated internalizing and externalizing outcomes are discussed as are the implications for the bullying prevention.

본 연구의 목적은 홍수피해 잠재능 산정을 위하여 항목별 가중치 산정을 통한 계층화분석기법의 적용성을 평가하고자 한다. 홍수피해 잠재능 산정의 경우 유역의 특성에 따른 다양한 항목과 가중치를 적절하게 고려하여야 한다. 그러나 도시화 지역의 경우 외수력과 우수관 미설치에 대한 고려 없이 미리 정해진 절차에 의해 이루어지므로 실제 현장 조건을 정확하게 모사하지 못하고 있다. 따라서 위에서 언급한 것과 같이 두 가지 주요 항목을 홍수피해 잠재능 산정 절차에 반영하여 실제 상황을 보다 잘 모사하고 다양한 전문가 집단의 설문 결과를 반영하여 보다 정확한 판단을 하는 것이 필요하다. 연구결과 항목별 가중치 산정은 주요 항목의 가중치를 산정하는데 효과적인 것으로 나타났다. 또한 외수력과 우수관 설치를 고려한 수정 방법은 홍수피해 잠재능 산정에서 보다 좋은 결과를 제시하였다.

The purpose of this study was to identify the latent classes in the changing patterns of marital conflict perceived by mothers to explore its relationship with the changing patterns of mothers' depression, school readiness, self-esteem, and happiness of their children five years after their birth. A total of 1,243 responses from the 1st (2008) to 5th (2012) and 7th (2014) to 10th (2017) Korean Child and Youth Panel Study(KCYPS) were analyzed by Latent Growth Modeling (LGM) and Growth Mixture Analysis (GMA). The results were as follows. First, three changing patterns in the mothers' perceived marital conflict groups were identified: low-low changing, average-uptrend, and high-unchanging group. Second, an increasing pattern of depression was found from mothers of high-unchanging group over five years. Third, school readiness for their children was differentiated according to the latent classes. In particular, children from the low-low changing group showed higher readiness as well as self-esteem and happiness. Fourth, children from mothers of the low-low changing group showed high self-esteem and happiness in lower grades in elementary school. The results of this study suggest that the mothers' perceived marital conflict had an influence on themselves as well as their children's school related behaviors. Suggestions for an intervention program to resolve marital conflict are also discussed.

The purpose of this study was to identify latent classes in changes of mothers' daily life stress over six years from multicultural families and to test its relationship with early adolescents' perceived neglecting parental attitudes and their academic achievements. For achieving this purpose, as the study sample 1,039 students were gathered from the 4th grade of elementary school to 3rd grade of middle school, using Growth Mixture Modeling, Multiple Group Analysis, and One-way ANOVA. The results were as follows. First, latent classes of mothers' daily life stress were categorized into three types: high-stable trajectory, moderate-changing trajectory, and low-changing trajectory. Second, these three types showed different characteristics in early adolescents' perceived neglecting parental attitudes and academic achievements. Third, early adolescents' perceived neglecting parental attitude were not significant determinants of the latent classes while academic achievements were. The findings of this study may provide a framework for understanding the relationships among mothers' daily life stress and early adolescents' perceived neglecting parental attitudes and their academic achievements in multicultural families and practical implications for providing social support to overcome daily life stress of mothers in multicultural families.

This study explored what latent classes appear according to the combination of Belief in a Just World (BJW) and social class of middle-aged adults, and examined whether there are differences in career transiton, perceiving a calling, and working as meaning in each class and what characteristics they have. 224 middle-aged people who experienced turnover through online and offline were surveyed and analyzed by Latent Profile Analysis. The participants were divided into 5 latent classes such as; 'Relative self-satisfaction', 'Social contentment', 'Relative deprived', 'Fairness trust' and 'Fairness distrust'. According to the results of MANOVA analysis to figure out if there are differences in career transitions, perceiving a calling, and working as meaning depending on latent classes, significant differences were appeared among latent classes. Finally, multinominal logistic regression analysis was conducted to examine whether demographic characteristics and 'decent work' affect the latent group classification. As a result, the more 'decent work', the higher the probability of belonging to the class with high BJW and social class. On the basis of the results of this study, the implications on the case conceptualization and counseling strategy for adults focusing on BJW and Social class in adults and future research were discussed.

The purpose of this study is to analyze the self-directed learning types of software education learners and to characterize them according to each type. To do this, 429 middle school students participating in online software education at K university were surveyed and a latent class analysis to analyze self-directed learning types was conducted. As a result, the self-directed learning types of the software education learners were classified into 'highest level of self-directed learning type (class 1)', 'self learning style recognition type (class 2)', 'self learning style preference type (class 3)', and 'lack of self-directed learning type(class 4)'. Also, the level of software learning achievement according to self-directed learning type of software education learners was found to be the highest at 'highest level of self-directed learning type (class 1)' and lowest at 'self learning style preference type (class 3)'. Based on these results, we suggested the strategic implications for software education.

This study is aimed to identify latent classes which are based the change patterns in assistive technology device use among worker with disabilities and to test the effects of independent variables(gender, education, disability type, disability density, activity and participation of ICF: ICF, subjective socioeconomic status: SES, job satisfaction, life satisfaction) on determining latents classes. This study applied Nagin's(1999) semi-parametric group based approach to the panel survey of employment for the disabled. Because dependant variable has dichotomous scale, logit model was used. The results identified three latent classes, which could be defined based on the patterns as follows; assistive device continued use group, assistive device mid-level use group, assistive device sharp decline use group. The effects of the independent variables on the latent classes was tested by multinomial logit analysis. The results showed that education, disability type, ICF, SES, and life satisfaction were significant determinants of the latent classes. Finally, the implications based on analysis results were suggested.

This study examined the trajectories of the marital satisfaction of parents to classify its latent classes and how marital satisfaction influences the behavioral problems of their children between the identified latent classes. The 1st to 8th and 10th data from the Korea Child-Adolescent Panel Survey were analyzed using the latent class growth analysis and BCH method. First, based on the mother's trajectory of marital satisfaction, five latent classes were identified: 'low constant', 'intermediate constant', 'temporary increment-constantly decrement', 'high constant, and 'highest constant'. At the same time, based on the father's trajectory of marital satisfaction, four latent classes were identified: 'increment', 'intermediate-slightly decrement', 'high-slightly decrement', and 'highest constant'. Second, mothers with low marital satisfaction had more children with behavioral problems, and their influence had more problems with internalized behavioral problems. These problems progressed to externalized behavioral problems as they grew. Both internalized and externalized behavioral problems were also found between the identified latent classes of the father's marital satisfaction. Children of fathers with low marital satisfaction showed more behavioral problems. These findings suggest that the marital satisfaction of parents is an important variable that can influence the behavioral problems of their children.

This study had two aims (1) to explore the trajectory of family functioning (flexibility and cohesion) in the mothers' perspective and classify it according to the development of their child, and (2) to examine the differences in children's self-esteem as well the internal and external behavioral problems based on the latent groups. A total of 1,348 mothers and their children who participated in the survey in 2013 through to 2017 were analyzed. The group was subdivided into low incremental, average incremental, average-above incremental, and high unchanged groups according to the flexibility, and into low incremental, average incremental, decremental, high incremental, and above-high unchanged groups in terms of cohesion. From 2015 to 2017, the self-esteem of elementary school-age children showed differences depending on the flexibility and cohesion of family functioning; children in the high-unchanged group of flexibility and the above-high unchanged group of cohesion showed high self-esteem. Behavior problems of early childhood and elementary school-age children varied according to the latent classes of flexibility and the cohesion of family functioning. Children in low incremental and average incremental groups of flexibility and low incremental, average incremental, and decremental groups of cohesion showed more internal and external behavioral problems. These findings suggest that family functioning has significant effects on the psychological aspects of children.
