This study aimed at developing parent education program for family leisure for parents of adolescent children to enable them to pursue happy lives as healthy families with adequate balance of cohesiveness and adaptability and smooth communication between the members of their families after parent education for family leisure. Research procedure of parent education program for family leisure proceeded with establishment of theory and requirement survey through precedent research, design of program, practice of program, evaluation of program and suggestion of revised program model after evaluation. On the basis of evaluation results, parent education program for family leisure aiming at parents of adolescent children can conclusively be revised as follows. The first session aims at understanding of family leisure; the second session aims at improvement of learning effect through education & experience-oriented activities; the third session aims at understanding and paying regard to their children through hobby-oriented activities; the fourth session aims at improvement of social relations through society-oriented activities; the fifth session aims at helping children education through check of communication in family-oriented activities and home-visiting education for etiquette; and the sixth session, the final session, aims at providing information and knowledge on family leisure and letting them gain better understanding of adolescent children.

Social deficits are the most critical and core deficits of the children with Autistic Spectrum Disorder(ASD) and they are qualitatively as well as qualitatively different from typically developing children. It is proposed that the attachment between the mother and the autistic child should be promoted foremost and early as possible, to improve social deficits, just like early social developments in normal children depend largely on interactions between the mother and the child who are attached to each other we have developed an interventional program, 'Attachment Promotion Therapy', largely based on the attachment theory. The Attachment promotion Therapy mandates the participation of both the mother and the autistic child, and consists of mutually enjoying play activities, close physical contacts and parental training on intense mother-child interactions, focusing on improving maternal sensitivity, responsiveness, and nurturing behaviors during their interactions. The program was found to be effective in improving attachment behaviors, attachment security and acquiring joint attention skills. Attachment Promotion Therapy is therefore proposed here as the important earliest intervention method for children with ASD and could become the base for many other educational and therapeutic interventions.

The study purpose was to investigate psychosocial factors related to smoking among adolescent boys. The Theory of Planned Behavior provide the basis for the study. Twenty-five attitudinal beliefs, 9 normative beliefs and 20control beliefs were identified through questionnaire development. The data were analyzed using t-test and χ2-test. Thirty-three percent of 300 students were smokers. Most of the beliefs examined were significantly different between smokers(n=92) and nonsmokers(n=92). With respect to attitudinal beliefs, smokers responded less negatively on the items of bad health effects of smoking such as sore throat, headache, chest pain, risk of cancer and bad blood circulation(p<0.001), and decreased physical strength(p<0.05). Smokers believed less negatively on the items that smoking leads to bothering others, bad breath, yellow teeth and making them spend money(p<0.001). In contrast, smokers felt more positively on smoking as a means of stress management, relaxing, helping digestion(P<0.001). Smokers felt less pressure for not smoking from significant others. Especially mother, siblings, friends, girl friends, seniors of school were important sources of influence regarding subject's smoking. Smokers felt less confident in controlling the urge to smoke in several situations including; when they were with friends or asked to smoke by friends; after the meal, or drinking; when they were bored or stressed, upset, and when they felt unstable(p<0.001). Smokers also scored lower on specific skills to quit or control the urge to smoke as well as overall perceived control, compared to nonsmokers(p<0.001). These results suggest that interventions for adolescents incorporate diverse strategies to increase the perceived control over smoking in specific situations as well as overall perceived control, to help them realize and modify attitudinal beliefs, and to elicit support from significant others for not smoking.

Research on biological aspects on adult depression has been subjected to more than 25 years of systematic research, while biologic investigations regarding childhood and adolescent depression are only now being initiated. Although no unifying, explanatory theory of the biologic etiology of childhood depression emerges from the results of studies reviewed above, the findings do support that biological factors may be involved in the genesis of childhood depression. The research reviewed in this paper suggests that age and pubertal factors have major effects in most biological markers of depression. Some of these markers, like sleep EEG and neuroendocrine markers should be broken down by decades during adult life span. Thus, although adult data are very valuable points of departure for biological research on child and adolescent depression, it is very hard to transfer the adult data to prepubertal children and adolescents, ignoring the biological changes that take place in growth and development, pubety and aging. A great deal of work in basic developmental neuroscience remains to be done. It will be crucial for further advances in this field to determine the normal patterns of neurotransmitter interaction in this age group and to study children at high risk for depression. It will be also crucial to use primate models of depressive illness in order to be able to answer the many queations that cannot be investigated in humans for ethical issues. Conclusively, much closer collaboration between developmental and neurobiological and behavioral studies in primates and in humans will be essential for further development.

Neurodevelopmental disorders are complex conditions that pose difficulty in the modulation of proper motor, sensory and cognitive function due to dysregulated neuronal development. Previous studies have reported that an imbalance in the excitation/inhibition (E/I) in the brain regulated by glutamatergic and/or GABAergic neurotransmission can cause neurodevelopmental and neuropsychiatric behavioral deficits such as autism spectrum disorder (ASD). NMDA acts as an agonist at the NMDA receptor and imitates the action of the glutamate on that receptor. NMDA however, unlike glutamate, only binds to and regulates the NMDA receptor subtypes and not the other glutamate receptors. This study seeks to determine whether NMDA administration in mice i.e., over-activation of the NMDA system would result in long-lasting behavioral deficits in the adolescent mice. Both gender mice were treated with NMDA or saline at early postnatal developmental period with significant synaptogenesis and synaptic maturation. On postnatal day 28, various behavioral experiments were conducted to assess and identify behavioral characteristics. NMDA-treated mice show social deficits, and repetitive behavior in both gender mice at adolescent periods. However, only the male mice but not female mice showed increased locomotor activity. This study implies that neonatal exposure to NMDA may illicit behavioral features similar to ASD. This study also confirms the validity of the E/I imbalance theory of ASD and that NMDA injection can be used as a pharmacologic model for ASD. Future studies may explore the mechanism behind the gender difference in locomotor activity as well as the human relevance and therapeutic significance of the present findings.

Purpose: This study was conducted to develop a scale for measuring aggression in adolescents, based on Ajzen's Theory of Planned Behavior (TPB). Methods: The participants were 38 adolescents in an in-depth study conducted to develop items for indirect measurement, 13 adolescents in a pre-test, and 289 adolescents in the present survey. The collected data were analyzed using content validity, the correlation coefficient, exploratory factor analysis, confirmatory factor analysis, reliability, and the Cronbach's ${\alpha}$. Results: In this study, the most important variable related to aggression was found to be aggression intention. This study included 4 factors of direct measurement and 6 factors of indirect measurement; therefore, 41 questions were developed. Increased levels of aggression were associated with higher scores for attitudes of aggression, subjective norms, perceived behavioral control, and aggression intention. Conclusion: We found that the questionnaire used in this study was valid and reliable as a measurement scale to explain aggression in adolescents based on TPB. Aggression intention should be included in aggression prevention programs because it was linked to aggressive behavior.

Purpose: This investigation examined a model to predict body mass index in order to prevent later development of obesity among adolescents. The hypothesized model was developed based on the principle of Social Cognitive Theory that social influences predict perceptions of cognition as well as behavior. Method: The 5,770 adolescents, aged 14-18 who participated in this study came from 11 separate school districts in Busan and Kyungnam province of South Korea. The adolescent surveys were administered in a group setting at the participating school. Of the 5770 surveys, adolescents with more than 10 percent missing data in the entire survey were excluded. The final sample contained 4,527 cases. The adolescents were included 2,250 (49.7%) males and 2,277 (50.3%) females. Data was analyzed Pearson correlation coefficients using SPSS 12 program and structural equation model (SEM) using Maximum Likelihood estimation was employed using Amos 5.0. Results: Social support directly affects cognitive determinants. Cognitive determinants directly affect behavior determinants which directly affect BMI. Cognitive and behavioral factors mediated the relationship between social support and BMI (GFI= 0.984, CFI= 0.974, RMSEA=0.031). Conclusion: Social levels should be supportive to help adolescents have healthier behaviors. This support can be accomplished by providing frequent support to establish positive cognitive factors as the foundation of the solution to prevent overweight and obesity.

This study analyzes the role of the Sorting Hat in structuring the identity of the characters in the Harry Potter series written by J. K. Rowling. In the different stages of adolescence, one explores and re-establishes one's identity. One's sense of identity is determined by the commitments made regarding personal and social traits. However, it is difficult to establish a concrete identity formation process theory that is communicable to adolescents. In Harry Potter, the characters' identities are reflected upon the Sorting Hat and are continuously molded throughout the book. The Sorting Hat provides nurturing experiences based on temperament. Based primarily on their temperament, it sorts the students into four houses, each with their own distinct characteristics. Once sorted, the houses become the living and learning communities in which the students share the same dormitory and classes until their graduation. Within the community, the students seek connections, supportive relationships, and understanding within the group. The taking on of the group identity is an explanatory variable in the formation of individual identity. The Sorting Hat provides the students with stability and a safe boundary. After being sorted based on their temperament, the inexperienced and immature adolescents can explore different options under the guidance of the Hat before making a definite commitment. By presenting them with an appropriate environment (such as a mentor, friend, or family member), the Hat further shapes their identity and integrates the identity elements ascribed in the beginning. By providing experiences and interactions based on their unique temperament and environment, the Sorting Hat plays a crucial role in establishing the students' identities. The Sorting Hat can be an ideal model for finding one's identity during adolescence.

Many child actors have appeared in various movies as the Korean film industry continues to evolve. As more children appear in violent and raunchy scenes, there are more concerns about the movie's effect on child actors. In some Western countries, many strategies have been developed for child actors, but for the Korean movie industry, the conditions are still poor for them. Although children who enter the concrete operational period are able to think logically and systematically, they are yet limited by their experiences. Adolescents in the formal operational period try to deal with all of the possibilities and assumptions logically and systematically with freedom from realistic contents and experiences. This period is very important because adolescents become more sensitive to others' feelings and they should develop their ego identity. Several studies have reported the indirect experiences through media including how the movie affected children and adolescents negatively. Depending on the individual's morality, judgment and emotional status, these effects were variable and inconsistent and could be relieved by several interventions. We could anticipate much bigger emotional effect on child actors who are acting directly and then are confronting themselves in the scene. Therefore, we suggest that the emotional effects of the movies on child actors can be managed properly by considering children's cognitive ability and emotional status, and establishing protective strategies before they are exposed to problematic scenes. Of course, it should be followed by evaluating them after the exposure and with follow-up management, if necessary.

This research applied an attachment theory to the study of three generations of women. Questionnaire and semistructured interview techniques were employed to collect the data on intergenerational mother-daughter relationships from 140 triads of adolescent daughters middle-aged mothers an old-aged grandmothers. The focus of the study had been on the characteristics of attachment patterns which is measured by sense of attachment and autonomy across and within generations and their effects on personal well-being. Women in each their three generations perceived a high and seminilar level of attachment across and within the generations. On the other hand the level of autonomy differed by the generations with middle-aged mothers showing a higher level of perceived sense of autonomy than other two generations. Although the levels of attachment and autonomy were related to psychological well-being the level of autonomy was slightly more related to it. The results also showed that not nly one's own attachment toward mother/daughter but attachment of others toward herself were associated with the personal well-being. Overall this study reflects and supports the basis concepts of mother-daughter attachment: its continuity reciprocity and personal development in adulthood.
