  • The purpose of our study was to figure out the generation gap between adolescents group and parents group in the sub-dimensions of perceptions on online games, such as harmfulness and benefits of online games, impacts and values of online games, parent-adolescent relationship with regard to online game activities, and government regulation of online games. To this end, we conducted online survey targeting middle or high school students and parents with children attending middle or high school regarding the perceptions on online games. As a result, we identified the similarities and differences between adolescents and parents generation in the sub-dimensions of perceptions on online games. Especially, we found significant differences between adolescents and parents generation in the perceptions on violence and sociality of online games. This result shows that the generation gap in these two factors may cause the conflict between parents and adolescents with regard to online game activities. Also, we ascertained the significant generation gap in the perception on parent-adolescent relationship with regard to online game activities. This result implies that parent-adolescent relationship in the developmental process of adolescents in real life was reflected in the perception on parent-adolescent relationship with regard to online game activities. Our contributions are in specifying the generation gap in the sub-dimensions of the perceptions on online games and in identifying the main causes of the conflict between parents group and adolescent group with regard to online game activities.

  • As the role of volunteers in disaster settings has been growing overtime, the present study was aimed to understand voluntary disaster workers with their burnout pattern and examine group differences in their secondary traumatic stress and world assumptions. Total of 70 voluntary workers who served for recovery from Sewol ferry disaster participated in this study. Using cluster analysis, we identified three distinct cluster groups on the basis of three burnout subscale scores(emotional exhaustion, personal accomplishment, depersonalization): Group 1 was characterized by the highest score on personal accomplishment and low levels of emotional exhaustion and depersonalization. Group 2 scored the highest on emotional exhaustion and depersonalization, and relatively high on personal accomplishment. Group 3 was characterized by the lowest scores on three subscales. Results from χ2 tests showed that groups differed significantly on types and the period of support activities. Analysis of variance was conducted to identify further group differences. The results indicated that Group 2 scored the highest on secondary traumatic stress, while Group 1 scored the highest on worthiness of the self. Finally, the clinical implications and limitations of these results as well as suggestions for further research were discussed.

  • Previous studies indicate that depression is strongly correlated with suicide, suggesting that individuals with higher levels of depression are more likely to commit suicide. Statistical data, however, show that depression is more prevalent among females whereas suicidal incidents are much higher among males. Using the 1st Seoul Welfare Panel Data, this study aims to examine the association between depression and suicidal attitudes and further examine whether there is gender and age difference in the relationship. Sample consists of 7,396 individuals aged 18 and over. Research questions were answered through the structural equation modeling(SEM) and multi-group SEM. The results showed that (1) depression is significantly associated with suicidal attitudes, replicating the previous findings, (2) the association was much higher among males than females, suggesting that depressed males are more vulnerable to suicide than depressed females, and (3) the gender difference was primarily caused by the group of women aged 65 and over. Based on these findings, implications for theory and practice were discussed.

  • This study constructed an experiment group and a comparative group, composed of high school students preparing for "Na" type math exam and provided one-to-many tutoring cooperative learning. This study tested the differences between group and between pre- and post-treatment scores by group using non-parametric statistics techniques. Moreover, this study conducted an open-type survey twice and had individual interviews to examine the affective domains of students. The difference in scores between the experimental group and the comparative group was not significant. However, the difference between pre- and post-treatment math scores was only significant in the experiment group among the three groups. Additionally, the student-teacher could reflect on him or her and improve self-efficacy while teaching other ordinary students. The ordinary students were more interested and motivated in the lessons and became more confident. In terms of mathematics competency, we could see that communication, problem-solving, reasoning, and attitude & practice were improved.

  • The purpose of this study is to classify the customers according to the characteristics of the relational benefits and to compare the performances of the sub-groups. As a result of the research, the group type according to the relational benefits was subdivided into 3 groups, and each group was named emotional relational group, continuous relational group and intermittent relational group considering customer characteristics. First, the emotional relational group is the group that emphasizes the empathy and assurance between the service provider and the customer, and the continuous relational group is the group with the highest social, confidence and economic benefits. The intermittent relational group was simply a transaction-oriented group. This implies that a differentiated customer management strategy is needed for each relational benefit group based on customer experience in medical services.

  • On the basin of RAPD analysis, genetic diversity and structure of the natural populations of Abies holophylla was estimated by AMOVA procedure. The average value of percent of polymorphic markers was 71.9%. Most variation existed among individuals within population(80.2%). Genetic differentiation among populations(${\Phi}_{ST}$) was 0.198. When the populations were grouped as two region(i.e., Taebaek and Sobaek Mountain Regions), 8.5% of the total genetic variation was explained as regional differences. The heterogeneity of molecular variance among populations was investigated with Bartlett's test, which revealed that populations of Mt. Taebaek and Mt. Gariwang were more heterogeneous. Generally, the populations of Taebaek Mountain Reion were more heterogeneous than those of Sobaek Mountain Reion. Finally, the applicability of AMOVA to the populations frenetic study was discussed in comparison with other measures of genetic differentiation which were widely used.

  • The purpose of this study is to analyze the difference between local residents and tourist groups in the relationship between the motivation for visiting and the satisfaction of Chung Nam Dae which is the leading tourist attraction in the Chungbuk region. We obtained 200 validated samples each of the local residents in Chungcheongbuk-do Province and the tourists from outside of Chungcheongbuk-do Province with experience of visiting Cheongnamdae through the survey using the questionnaire organized through literature research. The analysis result showed that the relationship between motivation and satisfaction varied depending on the overall sample, local residents, and tourist and that the natural relaxation and convenience had a positive impact on satisfaction in all groups. There was a difference in the influence between motivation and satisfaction between the two groups. Four motivational factors, including natural relaxation, convenience, historicity, and relationship had the significant influence on satisfaction for the local residents while two motivational factors, including natural relaxation and convenience, had the significant influence on satisfaction for the tourists. Based on the results of the study, we presented the theoretical and practical implications and suggested follow-up studies.
