  • The global popularity of K-content(Korean Wave) has led to a continuous increase in copyright infringement cases involving domestic works, not only within the country but also overseas. In response to this trend, there is active research on technologies for detecting illegal distribution sites of domestic copyrighted materials, with recent studies utilizing the characteristics of domestic illegal distribution sites that often include a significant number of advertising banners. However, the application of detection techniques similar to those used domestically is limited for overseas illegal distribution sites. These sites may not include advertising banners or may have significantly fewer ads compared to domestic sites, making the application of detection technologies used domestically challenging. In this study, we propose a detection technique based on the similarity comparison of links and text trees, leveraging the characteristic of including illegal sharing posts and images of copyrighted materials in a similar hierarchical structure. Additionally, to accurately compare the similarity of large-scale trees composed of a massive number of links, we utilize Graph Neural Network (GNN). The experiments conducted in this study demonstrated a high accuracy rate of over 95% in classifying regular sites and sites involved in the illegal distribution of copyrighted materials. Applying this algorithm to automate the detection of illegal distribution sites is expected to enable swift responses to copyright infringements.

  • The purpose of this study was to explore the factors related to social participation of Korean young-old adults residing in urban area with a focus on the effects of various motivations. In addition, this study examined gender differences in the relationships between social participation and motivations of social participation. Self-oriented motivation, network-oriented motivation, and society-oriented motivation were considered as motivations of social participation. The study subjects were 836 men and 877 women aged 50-69. The data were collected through face-to-face interviews using structured questionnaires in 2009. Hierarchical regression analysis was conducted to examine the relationships between motivations and the level of social participation using the SAS program. Main results were as follows: 1) The network-oriented motivation and society-oriented motivations were significantly related to the level of social participation; 2) Although men and women significantly differed in the patterns of social participation, gender differences were not found in the relationships between the social participation and motivations. These findings imply that network-oriented motivation and society-oriented motivation are important for facilitating the social participation of Korean young elderly. Further implications were discussed.

  • As S. Korea is aging faster than any other industrialized countries, there exists a need to understand how best to improve the quality of life of the elders. The main purpose of this study is to examine the predictors of life satisfaction in the nationally representative sample of adults aged 65 and older (n=4,155) drawn from the Wave I (2006) of the Korean Longitudinal Study on Aging. Hierarchical multiple regression analysis was run to assess the unique explanatory contribution of socio-demographics, social network, activity participation, and physical/psychological health on the life satisfaction. Three separate analyses were undertaken to note differences by education level: older adults with no formal education, those who had completed 9th grade, and those who had completed 12th grade and more. There are three main findings: 1) Physical/psychological health variables such as subjective health, regular exercise, and depression were significant predictors of life satisfaction regardless of education level; 2) While social network and activity participation factors influence life satisfaction of the two lower education groups, such factors don't affect the highest education group; 3) Marital status, household income, and location of residence were significant demographic predictors of life satisfaction regardless of education level. Implications for program development and policy are discussed in this paper.

  • This study aimed to investigate the association between social support and the change of depressive symptoms and its difference by gender among Korean Baby Boomer. We used the Korean Longitudinal Study of Aging (KLoSA) 5th (in 2014) and 6th waves (in 2016). Samples were Korean Baby Boomer (born 1955 to 1963) who have spouse and children(N = 1,210). Dependent variable was depressive symptoms and independent variables were four social support variables (spousal relationship satisfaction, parent-child relationship satisfaction, frequency of social contact, and number of participation groups). Interaction variables between social support and gender were also included in the model. Hierarchical regression analysis with the lagged dependent variable was performed. Results showed that the higher the satisfaction of spousal relationship and the satisfaction of parent-child relationship, the less the depressive symptoms increased. All interaction variables were not significant. These findings mean that the support from the spouse and the child is helpful in lowering depressive symptoms, and the associations between social support and depressive symptoms are not different by gender among Baby Boomer. It implies that interventions for enhancing family relationships, especially spousal relationship and parent-child relationship, may be useful to reduce depressive symptoms among Korean Baby Boomer.

  • The purpose of this study was to examine and compare factors affecting the subjective life expectancy among the elderly, and to suggest health practice and social welfare service implications for later life. A total of 4,483 seniors from the 6th wave(2016) of the Korean Longitudinal Study on Aging (KLoSA) were used for analysis. The subjects were divided into three age groups: the young-old (n=2,106, 65~74 years), middle-old (n=1,803, 75~84 years), and oldest-old (n=574, 85 years and older). Control variables were sociodemographic factors and health status factors. Independent variables were health promotion behavior, cognition of public care, participating social activity, economic activity, and receiving basic pension. The data were analyzed using hierarchical multiple regression. The main results were as follows. Health promotion behavior was associated with the young-old. Social activities and economic activity were associated with the young-old and middle-old. Receiving basic pension had a significant impact on all age groups. In the middle-old, significant results were focused on socio-demographic and health status factors compared to other groups. The results of this study will provide basic data for the elderly policy and welfare service and will help to find and improve the important factors for the life of the elderly.

  • The purpose of this study is to examine whether middle-aged people's anxiety about economic well-being in old age affects problem drinking and to verify whether there is relationship between anxiety about economic well-being in old age and to examine the problem drinking could be mitigated by social supports. We used the 2015 Korean Adults' Psycho-Social Anxiety Survey data. To detect the moderating effect of social supports, we employed a method of hierarchical multiple regression analysis. The result of the study showed that the higher the anxiety about economic well-being in old age among middle-aged adults, the higher was the likelihood of problem drinking. Moreover, the relationship between anxiety about economic well-being in old age and problem drinking could be moderated by social supports. Based on the empirical findings, this study suggests that education to deal with middle-aged people's anxiety about economic well-being in old age should be developed and recommends that counseling and community programs for social supports to be implemented as a preventive approach.

  • This study set out to investigate implementation agency effect on participants' self-sufficiency in self-support program. Self-support program's implementation agency consist of civil groups and social welfare corporations. The final sample size was 602 program participants and 18 implementation agencies in Gwangju city, South Korea. Two-level hierarchical linear model was used for analysis. The major findings of this study are as follows. First, civil groups' participants were healthier, more often participated in business model, earned higher monthly income, participated shorter time rather than participants in social welfare corporation. Second, civil groups' participants showed low level of self-sufficiency than participants in social welfare corporations. These results means that self-support policy is not delivered uniformly because front-line implementation agencies develop work habits that influence the outcome of policy. And limitations and implications of this study were discussed with respect to further studies.

  • This study investigated the differential interactive effects of the combination of driving confidence and sensation-seeking on driving anger among different age groups, by using correlation analysis, a hierarchical regression and ANOVAs for the data gathered through the questionnaires administrated in a form of face-to-face interview. The results showed the followings. First, males tended to show higher level in driving anger than females. Second, whereas sensation-seeking was positively correlated with driving anger, age and driving experience were negatively correlated with driving anger, respectively. Third, although there was no significant relationship between driving confidence and driving anger among the drivers aged under 40 years, the drivers aged over 40 years showed higher level of driving anger as their driving confidence increased. Forth, level of sensation-seeking was found to be a strong predictor of driving anger in all age groups. Fifth, driving confidence and sensation-seeking appeared to affect the level of driving anger interactively among drivers aged under 40 years or over 65 years, resulting in higher driving anger only when both the levels of driving confidence and sensation-seeking were high. In contrast, driving confidence and sensation-seeking affected driving anger independently among the drivers aged 30-49 years. Implication and suggestion were discussed.

  • The aim of the present study was to examine moderating effects of self-esteem on perceived transgression wrongness and forgiveness defined as Worthington and Scherer's (2004) emotional forgiveness and decisional forgiveness when receiving apologies. Data collected from 861(486 males, 375 females) Korean college students were analyzed with hierarchical multiple regression analysis. The results were as follows. First, on emotional forgiveness, the two-way interaction effect of perceived transgression wrongness and explicit self-esteem was significant. And on decisional forgiveness, the two-way interaction effect of perceived transgression wrongness and explicit self-esteem was significant. The effect of perceived transgression wrongness on emotional and decisional forgiveness for individuals with high explicit self-esteem is stronger than its impact for individuals with low self-esteem. These findings show that explicit self-esteem may play an important role in forgiveness in college students through interactions with perceived transgression wrongness. Second, on emotional forgiveness, the three-way interaction effect of perceived transgression wrongness, explicit self-esteem, and implicit self-esteem was significant. The effect of perceived transgression wrongness on emotional forgiveness for individuals with high explicit self-esteem having high implicit self-esteem is stronger than its impact for individuals with low explicit self-esteem having high implicit self-esteem. These findings show that discrepancies between implicit and explicit self-esteem are detrimental to emotional forgiveness. But, on decisional forgiveness, the three-way interaction effect of perceived transgression wrongness, explicit self-esteem, and implicit self-esteem was not significant. Implications and limitations of this study were discussed.

  • The purpose of the present study was to examine the relationship between individual values, nature-relatedness, and happiness in a sample of Korean university students(N=224). Specially, we used Schwartz's PVQ, life satisfaction, positive affect, psychological well-being, social well-being, and Korean Happiness scale to measure values and happiness. According to the bivariate correlational analysis, generally, there were positive correlation between benevolence, self-direction, universalism, stimulation and one of 5 happiness measurements and there was negative correlation between achievement and life satisfaction. Nature-relatedness were positively related with five types of happiness measurements. According to the hierarchical regression, demographic variables(sex, religion, economic levels), value types, and nature-relatedness explained 25%~36% of variance in happiness. Value was more related with psychological well-being than life satisfaction, positive affect, social well being, Korean happiness scale. This results emphasize the importance of healthy value(benevolence, self-direction) and provision of opportunities contact with nature to promote human happiness.
