There has been an enormous progress in understanding of how genes contribute to both normal and abnormal development. Also many laboratory works are exploring the intricacies of how to develop in the human central nervous system. Understanding the mechanisms of cortical development gives essential insight into the pathogenesis of many genetic and acqured developmental psychiatric disorders, including autism, schizophrenia, and teaming disorder. Genes have been implicated in an ever-increasing number of disorders. Advance in genetics have begun to clarify the molecular basis of not only single-gene disorders, but also more complex phenotypes.

This study aims to explore how to improve students' rights based on their age and development stages. To this end, we analyzed a survey that had been carried out with 1,065 students from elementary, middle and high schools in 2 most populated counties in Korea, focusing on the differences in their perception with regard to the right to survive, develop, be protected and participate. The result of the analysis showed that high school students' sense of rights was at the lowest in general, while being particularly low in their sense of participation rights. However, when it comes to the development rights and protection rights, the level of recognition of middle school students were as low as those of high school students. Based on the results, we suggested that a proactive effort to guarantee adolescents' participation rights is required, and that education of human rights should be emphasized not only for children but also for their supporters. In the follow-up study, it is required to investigate the differences between development stages and regions by including participants with diverse ages and residential areas.

Purpose: Floppy infants or congenital hypotonia indicates decreased muscle tone in infants secondary to abnormalities of the central or the peripheral nervous system, or both. Previous literature classified its causes as those attributable to a central vs. peripheral origin; however, recent studies have introduced a newer classification describing a combined origin. We invenstigated floppy infants by applying the new etiological classification and reviewed the most common etiologies based on the age of presentation. We additionally reviewed the clinical characteristics, diagnoses, and the developmental outcomes in these infants. Methods: We retrospectively reviewed the electronic medical charts and recruited 116 infants diagnosed with floppy infant syndrome between January 2005 and December 2016 at Severance Children's Hospital. Among these infants, 66 with a confirmed diagnosis were reviewed for the etiological classification. Information regarding developmental outcomes was obtained via phone interviews with the infants' families. Results: Based on the new etiological classification, among 69 infants with a confirmed diagnosis, in 40 (34.5%) this syndrome was of central origin, in 19 (16.4%) of peripheral origin, and in 10 (8.6%) of combined origin. Prader-Willi syndrome, myotonic dystrophy, and spinal muscular atrophy were the most common disorders observed and combined hypotonia showed the poorest developmental outcome. Conclusion: The study states the importance of proper evaluation of etiological diagnosis and optimal intervention for developmental prognosis. The introduction of a new etiological group of combined hypotonia especially emphasizes regular monitoring and timely rehabilitative intervention in patients for the better quality of life in them as well as their caregivers.

The purpose of this study was to examine the developmental trajectories of adolescents' internalizing problem behaviors. The data came from 3,188 middle school students through their participation in the Korea Youth Panel Survey(KYPS). Adolescents with a high level of internalizing problem behaviors in the first year showed a rapid decline in these behaviors over time, whereas for adolescents with a low level of these behaviors in the first year the decline was slow. The predictors of the developmental trajectories were related to individual variables, such as gender, self-esteem, self-control, stress, self-stigmatization, and academic achievement. The developmental trajectories of adolescents' internalizing problem behaviors were classified into four groups. The predictors of the patterns of developmental trajectories in adolescents' internalizing problem behaviors appeared to be related to individual variables.

The purpose of this study was to investigate the influence of adolescents´ perception of the fathers´ child-rearing on their self-efficacy and achievement motivation. The subjects of this study were 456 adolescents from 3 middle schools located in Seoul and GyeonggiDo. The main results are as follows. (1) There was a significant correlation between the father´s child-rearing involvement and the adolescent´s self-efficacy. The father´s ‘day-to-day guidance’ was the best predictor of the adolescent´s self-efficacy. (2) There was a significant correlation between the father´s child-rearing involvement and the adolescent´s achievement motivation. The father´s ‘day-to-day guidance’ was the best predictor in predicting the adolescent´s achievement motivation. In conclusion, the adolescent´s perceived father´s child-rearing involvement were found to be significant variables in predicting the adolescent´s self-efficacy and achievement motivation.

The purpose of this study was to identify the influence of youth group activities experience to sociality development of middle school student. To achieve above study purpose, the subject of this study was selected 280 from middle school second-grade students(youth group activities participants 140, non-participants 140). Experience based activities were applied to the experimental group over 80 hours per year and the pre-post test was conducted using the sociality development inventory. The results of the data were analyzed by t-test using the SPSS(ver 18.0) program. The results were as follows: First, In the aspect of sociality development by youth group activities, the student participant showed somewhat significant differences compared to the non-participants. Second, considering the activity periods, the students with more than two-year experiences showed higher results than the ones with just one-year experiences. These results represent that various programs, which can develop the sociality, can be provided for youth when they join any group of activities in general and those programs are also very effective in developing the sociality of juveniles. Furthermore, It is suggested that youth group activities are a necessary element at the school education fields, which can solve the various problems caused by overemphasizing only the knowledge transfer, reinforced education of humanism and reduced school violence.

청소년 흡연률 세계2위, 아시아 1위, 활발히 확산되는 범사회적 금연운동에도 불구하고 청소년 흡연률은 오히려 늘면 늘뿐 줄어들지 않고 있는 상황이어서 이를 바라보는 국민의 심정이 안타깝기 그지없다. 사태가 이렇게 심각하게 된데는 여러 이유가 있겠지만 우리 사회가 너무 청소년 흡연을 방치하지 않았나 한번쯤 심각히 반성해야 할 부분이다. 청소년 흡연방지를 위한 보다 적극적이고 실효성 있는 정책과 성인들의 관심과 질타 등이 있었다면 상황은 분명 지금보다는 나아졌을 것이다. 지금보다 실효성 있는 청소년흡연 억제 정책이 시급한 상황에서 그 위기를 구원할 릴리프로 담배자판기를 등판시킨다면 과연 어떨까? 과거만 해도 담배자판기 청소년 흡연조장이라는 이유로 길거리에서 철수되어야 하는 아픔을 겪었고 아직도 그러한 오명으로부터 자유스러울 수 없는 상황이지만 산업계의 기술발달은 이제 과감하고 자신있게 등판을 자청할 상황이 되었다. 위기에 등판한 릴리프는 성인인식장치라는 강력한 강속구로 자신 있게 청소년 흡연증가라는 강타자를 삼진 아웃 시킬 수도 있는게 현상황인 것이다. 문제는 정부관련부처의 담배자판기를 보는 시각변화와 신뢰이다. 100%청소년이용을 차단할 담배자판기를 이용, 기존 유인 담배 판매 유통수단을 대체한다면 청소년 담배구입 루트를 근원적으로 차단할 비법이 있는 마당에 담배자판기를 언제까지나 색안경을 끼고 봐서는 안될 것이다. 이러한 취지 하에 협회에서는 대정부 관련부처 설득을 진행해 가고 있다. 최근에는 청소년보호위원회 홈페이지를 통해 '청소년 흡연 감소를 위한 실질적 대책에 대한 질의 및 제언' 이라는 제목으로 성인인식담배자판기의 적극 활용을 촉구하는 민원을 제출했다. 이제는 정부관련부처의 마인드 변화, 산업계 및 여론의 지지 등이 삼위일체가 되어야 하는 상황에서 온라인 상에 게재된 하기의 내용이 적극 호응과 지지를 받았으면 하는 바램이다.

The anatomical structure of the brain reflects a great amount of information about an individual's cognitive ability. The present study reviewed research on developmental changes in brain structure in relation to biological maturation and intellectual growth focusing on children and adolescents. The purpose of the present study was to achieve an understanding of how children and adolescents' brain matures with development and also to examine whether individual differences in intelligence influences the development of brain structure. The first section introduces methods of measurement and analysis of brain structure, such as voxel-based morphometry and structural covariance. The second section reviews studies on the biological maturation of the brain and variables that influence brain development such as sex, environmental factors, and mental disorders, etc. The third section introduces the Parieto-Frontal Integration Theory of intelligence and reviews studies on the association between intelligence and developmental changes of the brain, including changes in structural covariance and functional connectivity. We conclude with a discussion on educational/clinical implications of this work and directions for future studies.
