The purpose of this study was to investigate the characteristics of internet usage among 5th and 6th grade of elementary school children and to elucidate the path model and the relative effects of various factors on internet addiction in the internet addiction tendency group. According to our results, the normal internet user group exhibit higher educational levels in fathers, secure attachment to mother, and warm friendship when compared to the internet addiction tendency group. At the same time, internet addiction group exhibit longer internet use time, a greater numbers of avatars in use, and higher avatars decoration costs. The research model suggested here was supported by the results. Attachment to mother appears to affect friendship which in turn affects avatars image decoration needs and avatars identification which in turn then has an impact upon internet addiction tendency. These results were then discussed in relation to previous research and theories.

The purpose of this research was to study differences between reciprocal and unidirectional friendships and to examine evidence on whether certain constituents of friendship can predict the termination of friendships. A total 375 subjects- 190 elementary and 185 middle school children in Pusan- were administered questionnaires two times at an interval of 3 months. Frequency, factor-analysis, t-test, discriminant-analysis, and cross classification analysis were applied for data analysis. The results of the study were as follows: 1) The different constituents of reciprocal and unidirectional friendships were statistically significant. That is, children in reciprocal friendships perceived their relationships more positively, felt closeness more strongly, and evaluated their friend more highly than the children in unidirectional friendships. 2) The termination of reciprocal friendships was predicted by the constituents of friendship. The most powerful predictor was the degree of closeness and the second powerful predictor was the degree of commitment to the relationship and the 3rd powerful predictor was perceived characteristics of the friend. The last powerful predictor was perceived characteristics of the relations. 3) There were no sex differences in the rate of termination of reciprocal relationships. 4) There were age differences in the rate of friendship termination of reciprocal relationships. That is, the rate of termination of reciprocal relationships among older children was higher than among younger children.

This study investigated the relationships between parental marital conflict, attachment to parents and peer relationships. The mediating role of attachment to parents was also explored in the relationship between parental marital conflict and peer relationships. Two hundred eighty four 8th graders participated in this study. The participants answered questionnaires regarding parental marital conflict, attachment to parents, qualify of their friendship, and attachment to peers. The main results of the study are as follows: First, adolescents who perceived a higher level of parental marital conflict reported less positive feelings and more negative feelings toward their friends. They also reported lower peer attachment, and tended to perceive their friendship functions negative. Second, adolescents who showed stronger attachment to their parents reported more positive feelings and less negative feelings toward their friends. They reported higher peer attachment, and perceived friendship functions positively. Third, adolescents who perceived a higher level of parental marital conflict showed weaker attachment to their parents. Finally, attachment to fathers and mothers mediated the association between parental marital conflict and peer relationships. In other words, parental marital conflict had an indirect effect on peer relationships. The results suggest that attachment to fathers and mothers that resulted from parental marital conflict played an important role in determining peer relationships among adolescents, rather than the existence of the parental marital conflict itself.

본 연구에서는 컴퓨터 실기 교과에서 나타나는 학생들의 개인차를 극복하기 위한 방안으로 동료교수법을 도입하였다. 중학교 3개 학급 학생들을 대상으로 실험 연구를 실시하여 동료 교수법이 강의식 교수법에 비하여 학업성취도에 차이를 가져오는지 알아보았다. 그리고 급우 관계에 의해 학생들이 희망하는 짝을 동료로 구성하는 방식이 기존의 성적 위주의 동료 구성 방식과 비교할 때 학업성취도 효과에서 어떤 차이가 나타나는지도 살펴보았다. 연구 결과 실기 위주의 컴퓨터 소양 교육에서 동료 교수법은 학업성취도에서 통계적으로 유의미한 차이를 보이지는 않았으나, 동료 교수법의 긍정적 효과를 확인할 수 있었다. 급우 관계에 의한 짝 구성 방식은 실험 처치 초기에는 통계적으로 유의미한 학업성취도 차이를 보였으나, 처치 기간이 경과함에 따라 동료 간 친밀도가 갖는 효과는 줄어드는 것으로 나타났다.

Objective: To evaluate the safety, feasibility, and efficacy of microwave ablation (MWA) for the treatment of primary hyperparathyroidism (PHPT). Materials and Methods: This study enrolled 67 PHPT patients (22 men, 45 women; mean age, 56.0 ± 16.3 years; range, 18-83 years) from January 2015 to December 2018. The laboratory data, including the serum intact parathyroid hormone (iPTH), calcium, phosphorus, and alkaline phosphatase (ALP) levels, were evaluated before MWA and again 2 hours, 1 day, 7 days, 1 month, 3 months, 6 months, 12 months, 18 months, and 24 months after. Results: Complete ablation was achieved with all 72 hyperplastic parathyroid glands found on the 67 patients enrolled, 64 of whom were treated in one session and 3 were treated over two sessions. The technical success rate was 100%. The median follow-up time was 13.6 months (range, 10.0-31.1 months). The clinical success rate was 89.4%. The volume reduction rate was 79.4% at 6 months. Compared to pre-MWA, the serum iPTH, calcium, phosphorus, and ALP levels had significantly improved 6 months post-MWA (iPTH, 157.3 pg/mL vs. 39.2 pg/mL; calcium, 2.75 ± 0.25 mmol/L vs. 2.34 ± 0.15 mmol/L; phosphorus, 0.86 ± 0.20 mmol/L vs. 1.12 ± 0.22 mmol/L; ALP, 79 U/L vs. 54 U/L, respectively; all, p < 0.01). Hoarseness was a major complication in 4 patients (6.0%), but it improved spontaneously within 2-3 months. Conclusion: MWA is safe, feasible, and effective for the treatment of PHPT.

This study investigated (1) the relation of aggressiveness to the outcome of conflict, intentional attribution, predicted response, and (2) friendship as a variable affecting intentional attribution and predicted response. The subjects are 78 fifth grade boys selected from a public elementary school located in Seoul. The children were individually tested by the researcher who read the items to the child. Dodge and Somberg's aggression questionnaire and Dodge and Frame's conflict outcome of ambiguosly intended stories were modified for use in this study. The instigator of aggression in the stories was classified as friend or non-friend and aggressive non-friend or nonaggressive non-friend. Two-way analyses of variance involving one between-subjects factor (aggression of subject) and one within-subjects factor (instigator combination) were performed on children's responses to three of the scales (hostile, neutral, positive). The results show that (1) there were differences in intentional attribution to the children's aggressiveness, regardless of the friendship status of the instigator, and (2) the predicted response to aggressiveness varied with type of instigator.

The purpose of this study was to assess risk indicators of depressive symptoms such as demographic, socio-economical domains (age, gender, marital status, education, child, religion, income, health, friendship) and personality domains (neurotic personality, self-esteem and life goal attitude) of community dwelling elderly persons. A total of 300 community-residing elderly participants aged 65+ in a metropolitan city in Korea, were recruited for this interview survey. The interview covered demographic and socio-economic characteristics, and administration of the 20-item Korean Version of CES-D, the 10-item Self-esteem, the 19-item Neuroticism and the 10-itm Goal Instability scale. The prevalence of significant depressive symptoms (CES-D scale >= 21) was 31%. Logistic regression analysis showed high risk for depression was associated with high neuroticism, less intimate friendship, high goa1 instability, and childlessness, respectively in the order of significance. Factors in the personality domains were more strongly associated with depressive symptoms than factors in the socio- economical domains. Both cultural and universal meaning of the findings was discussed with regard to intervention.

This paper deals with the emotional model of the software-robot. The software-robot requires several capabilities such as sensing, perceiving, acting, communicating, and surviving. and so on. There are already many studies about the emotional model like KISMET and AIBO. The new emotional model using the modified friendship scheme is proposed in this paper. Quite often, the available emotional models have time invariant human respond architectures. Conventional emotional models make the sociable robot get around with humans, and obey human commands during robot operation. This behavior makes the robot very different from real pets. Similar to real pets, the proposed emotional model with the modified friendship capability has time varying property depending on interaction between human and robot.
