This study was designed to investigate the relation between stress coping behavior and social adjustments in late childhood. Total 657 teenagers (238 ten-year-olds, 230 twelve-year-olds, and 189 fourteen-year-olds) and their parents living in Inchon area participated in the study. Each child was evaluated whether they cope either (a) defensively or (b) actively in several stressful domains by completing the Stress Coping Hating Scales (Korean). Their social adjustments were measured in areas like peer relationship, family relationship, and conformity with Social Adjustment Scales (Korean). The final examination scores were used to rate children’s Academic Achievements. Finally Korean version of Achenbach’s Child Behavior Check List were completed by parents. As results, girls were found to use more defensive strategies to cope stress, showed more conformity and withdrawn behaviors and achieved higher scores academically than boys. Generally younger children tended to adjust better socially than older children. As children grew older they used more and more defensive strategies to cope with everyday stress. Also older children showed more withdrawn behavior and aggressive behavior than younger children. As anticipated children who used more defensive coping strategies were reported to have more behavior problems, showed poorer social adjustments and academic achievements. Children who used more active coping strategies, on the other hands, were reported to haute less behavior problems, adjusted better socially and had better academia achievements. Finally children who adjusted better socially and had high academic achievements were reported to have less behavior problems.

FRP re-bar in concrete structures could be used as a substitute of steel re-bars for that cases in which aggressive environment produce high steel corrosion, or lightweight is an important design factor, or transportation cost increase significantly with the weight of the materials. But FRP fibers have only linearly elastic stress-strain behavior; whereas, steel re-bar has linear elastic behavior up to the yield point followed by large plastic deformation and strain hardening. Thus, the current FRP re-bars are not suitable concrete reinforcement where a large amount of plastic deformation prior to collapse is required. The main objectives of this study in to evaluate the tensile behavior and the fracture mode of hybrid FRP re-bar. Fracture mode of hybrid FRP re-bar is unique. The only feature common to the failure of the hybrid FRP re-bars and the composite is the random fiber fracture and multilevel fracture of sleeve fibers, and the resin laceration behavior in both the sleeve and the core areas. Also, the result of the tensile and interlaminar shear stress test results of hybrid FRP re-bar can provide its excellent tensile strength-strain and interlaminar stress-strain behavior.

An internet addiction measure(Park et al., 2001) and an asocial behavior measure(K. J. Lee, 1997) were administered to 232 6th-grade students. Statistical analyses were by mean-difference scores and t-test. Results showed that all aspects of internet addiction(preoccupation, compulsive use, relapse, tolerance/dependence and impediments in daily life) were related to both the inner asocial behaviors of depression, social withdrawal and over-anxiety and the external asocial behaviors of aggressiveness, delinquency and hyperactivity. The only exception was that tolerance/dependence was not related to delinquency. Boys addicted to the internet were more socially withdrawn, aggressive, delinquent and hyperactive than girls. From the results, it can be suggested that internet education should be carried out from the elementary educational level.

This study is to investigate dissatisfaction behavior of customers who purchase products on the Internet shopping mall and to find customers' dissatisfaction behavior types for effectively responding to that. Managing dissatisfaction behaviors are related to the customer satisfaction. To conduct this study, Call Center data was collected and analysed by qualitative method. The results showed that dissatisfaction of product quality and disappointment have different effects on post--purchase behaviors. Customers who feel more dissatisfaction with product quality showed the aggressive response such as exchange, refund, while customers who feel disappointment are likely to switch the shopping mall or to cancel the order. These results of customers' dissatisfaction behaviors indicate that company has to manage both product quality and the customer's experience dimension.

The subjects of this study on the relationships of locus of control, loneliness, and coping in the peer-alienation situation were 464 sixth grade children attending 4 elementary schools in Seoul. Analysis was by t-test, ANOVA, and Multiple Regression. Loneliness was higher in girls than in boys and in children with external locus of control. Passive coping in the peer-alienation situation was associated with higher levels of loneliness. Aggressive coping behavior in the peer-alienation situation was associated with higher levels of loneliness in boys. While both locus of control and passive coping behavior in the peer-alienation situation were predictive of loneliness in school age children, passive coping behavior was a stronger predictor of loneliness than locus of control.

Purpose: This study investigated differences in the relationships of factors including emotional problems, self-perception, parental behavior, and peer attachment with smartphone dependency (SD) among middle school, high school, and college students in South Korea. Methods: This study used data from a nationwide sample of 1,882 middle school, 1,821 high school, and 1,346 college students who owned smartphones. Descriptive statistics and multiple regression analysis were conducted to investigate the predictors of SD based on school level. Results: SD scores significantly differed across school levels. Female gender, more aggressive behavior, less ego-identity, and less monitoring parental behavior were linked to higher SD at all school levels. Less self-esteem and intrusive parental behavior were linked to SD in middle school students. In high school students, additional factors related to higher levels of SD were resilience, intrusive / inconsistent parental behavior, peer trust and alienation, and depression. Additionally, resilience, over-expectant parental behavior, and peer trust were linked to higher SD in college students. Conclusion: This study provides insights into SD and predictors of SD among middle school, high school, and college students. Based on these findings, SD prevention programs should be developed according to the developmental stages of adolescents and young adults.

본 연구는 운전자가 면대면 상황에서보다 익명상황에서 난폭운전을 더 많이 하는지와 익명상황에서 난폭운전을 많이 하는 운전자와 적게 하는 운전자 사이에 운전분노, 정서표현갈등 등의 내적 특성에서 어떤 차이가 있는지 살펴보았다. 연구 1에서 운전자 총 200명을 대상으로 조사를 실시한 결과, 면대면 상황에서보다 익명상황에서 난폭운전 수준이 더 높았다. 이어, 연구 2에서 운전자 총 384명을 대상으로 조사를 실시하였는데 익명상황의 난폭운전에 대해 이단계 군집분석을 실시한 결과, 응답자는 세 군집으로 나뉘어졌다. 익명상황에서 난폭운전을 많이 하는 운전자일수록 운전분노, 정서표현갈등 전체, 정서표현갈등의 하위 요인 중 자기방어적 양가성 요인의 수준이 높았다. 따라서 익명상황에서 난폭운전을 많이 하는 운전자가 운전분노를 많이 느끼며, 평소 정서를 잘 표현하지 못하고 갈등을 하는 경향이 있다고 볼 수 있다. 본 연구 결과는 난폭운전자에게 무조건적인 교통단속만을 행하기보다는 운전자 본인이 가진 문제점을 되돌아 볼 수 있게 하는 근본적인 대책 또한 필요하다는 것을 말해준다.

The objective of this study was to analyze children's maladjustment behavior as related to sex, temperament, and the mother's maternal attitudes, and to characterize the relative influence of these variables on the maladjustment behavior of 3-5 year old children in early child education centers. The subjects were recruited from Gwangju City, and included 217 mothers, and the teachers of their children. Statistical analyses were conducted using SPSSWIN(12.0) for Cronbach's alpha, t-test, one-way ANOVA, Pearson's correlation, and multiple regression analysis. The major findings are as follows; 1. Statistically significant differences existed in the maternal overprotective attitude group with regard to anxiety and withdrawal behaviors. 2. Boys evidenced more aggression, inattention, impulse, and anxiety behaviors than did girls. 3. The activity and adaptation factors of temperaments were significantly different. Increasing activity was associated with increasing aggressive behavior. Increasing adaptation was associated with higher levels of distraction. 4. In terms of maladjustment behaviors in the aggregate, the sex of the children appeared to be the most salient influencing factor, and the activity factor of children's temperament also exerted a significant influence, explaining 13% of maladjustment behavior.

The purpose of this study was to explore the effects of children's self-regulation and teacher-child relationships on children's social behaviors. Participants were 239 4- to 5-year-old children(114 boys, 125 girls) and their 23 teachers. The teachers completed rating scales to measure children's social behaviors and teacher-child relationships. Children's self-regulation was assessed by a mother reported questionnaire. Data were analyzed using descriptive statistics, Pearson's correlations and stepwise multiple regression analysis. The major results of this study were as follows: First, Children's social behaviors were partially correlated with children's self-regulation and teacher-child relationships. Second, The most influential factor by children's social behaviors was teacher-child relationship. Specially, teacher-child intimacy was the most powerful factor predicting children's asocial behavior and prosocial behavior. While teacher-child conflict was the most powerful factor influencing children's aggressive behavior, hyperactive-distractible behavior and anxious-fearful behavior. Findings are discussed in terms of the importance of teacher-child relationships in the context of program development and guidance for maladjusted children.

Purpose: Squamous cell carcinoma of the scalp sometimes exhibits unusually aggressive behavior. We report a case of extradordinarily aggressive squamous cell carcinoma of the scalp with invasion into the skull and dura mater. Method: The patient is a 38-year-old man with two cystic masses on the occipital area. He was diagnosed as squamous cell carcinoma in that region and have undergone surgical resections including cortical osteotomy of the skull, several years ago. On this occasion, 3-dimensional computed tomographic imaging revealed an erosive lesion on the occipital bone and magnetic resonance imaging showed two cystic masses invasion into the skull and dura mater. Results: He has undergone wide resection of the masses and cranioplasty with dural repair. Histopathologic examination indicated squamous cell carcinoma with moderate differentiation of the masses, bone marrow and dura mater. Conclusion: Squamous cell carcinoma on the scalp can readily penetrate the full thickness of the cranium and invade the dura mater, sagittal sinus and brain. We suggest wide resection of the scalp and split thickness skin graft with sentinel lymph node biopsy, following by postoperative radiation therapy.
