The purpose of this study is to investigate the effects of aerobic exercise and probiotics ingestion on motor learning and body weight in female mice during adolescence. The subjects were divided into six groups of variables, such as non-exercise, moderate, high-intensity exercise, probiotics ingestion, and non-probiotics, and then treated for four weeks. The vertical grid test was conducted before and after the treatment to evaluate motor learning and bodyweight. The high-intensity exercise and probiotics ingestion group showed fastest up, rotation, and down rate than the non-exercise group (p<.001). Also, a group that treated exercise and probiotics tended to record speedier performance than those that performed the only exercise. Comparing weight changes, the weight gain of a group that performed only moderate-intensity exercise was higher than that of a non-probiotics and non-exercise group (p=.032). Taken together, aerobic exercise during adolescence can help improve motor learning, and more efficient motor learning can be achieved when combined with probiotics ingestion.

This study systematically identified the influence of the school look fashion image on public culture, which is used for increasingly sexualized marketing appeal by domestic Girl Groups. We examined and analyzed the school look fashion image of Girl Groups, focusing on the Lolita complex which is particularly influential in the sexual appeal of domestic popular fashion. The method of this study is based on a literature review from the years 2007 to 2016, when the female girl groups began to receive attention. The music videos of the female girl groups in the top 100 charts of 'Melon' from 2006 to 2-16, which provides the largest mobile music service in Korea, were watched and analyzed as primary data. As a result, it was found that the 'school fashion look image' of adolescence which was used as costumes for Girl Groups, plays a role in commercializing the image of a 'girl', and the types and characteristics of school look fashion image are drawn in two ways. First, it is the image of a seductive Lolita complex. This is the case where young girls wear school look fashion image to emphasize their sexual maturity. Second, it is the case that is using the school look fashion image in order to perform with the 'young girl' concept, as an image of the enchanting Lolita complex; in addition, the erotic body image is more explicitly exposed through choreography and nakedness.

Objectives: Externalized behavioral problems are prevalent in adolescents, due to the difficulties associated with this developmental stage. Conduct Disorder (CD) and Oppositional Defiant Disorder (ODD), as well as other psychiatric disorders, such as major depressive disorder, result in the manifestation of many behavioral problems during adolescence. Methods: For this report, we analyzed a sample of 31 adolescents, each of whom had presented with CD or ODD at Chosun University Hospital between 2002 and 2010. We separated subjects into depressed and non-depressed groups according to their Beck Depression Inventory scores (BDI<10, non-depressed ; BDI${\geq}$10, depressed). Then we analyzed for neuropsychological differences between the depressed and non-depressed groups. Results: In our sample, adolescents in the depressed group showed less of a stealing (deceitfulness and/or theft) behavioral pattern and presented with more anxiety symptoms, lower self-esteem, and greater sensitivity in interpersonal relationships, as compared to the non-depressed group. Conclusion: When adolescents exhibit disruptive behavior, clinicians should consider the underlying causes of the behavior.

Modification of the diet during childhood and adolescence may be an effective strategy for maximizing the peak bone mass. Many supplementation studies have suggested a positive effect of the increased vitamin D intake on the bone mineral status in the elderly. However to date all studies have been conducted on old men and postmenopausal women. The aim of this study was to examine the effects of vitamin D supplementation on the bone mineral density and bone mineral content in growing rats. Twenty Sprague-Dawley female rats were divided into two groups; Control, and vitamin D supplementation. The bone mineral density(BMD) and bone mineral content(BMC) were measured using PIXImus in the spine and femur. Vitamin D supplementation did not affect the level of weight gain, mean food intake and food efficiency ratio. In addition, vitamin D supplementation had no added effect on the spine and femur BMD, and BMC. There were no significant differences in the spine BMD/weight and BMC/weight between the groups, but the spine BMD/weight and BMC/weight was 11 % higher in the vitamin D supplementation group. The femur BMD/weight and femur BMC/weight were significantly higher in the vitamin D supplementation group 9 weeks after the experiment. These results provide evidence of the beneficial effects of vitamin D supplementation on the BMD during the growth period.

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.

Purpose: The purpose of this study was to identify the experience of smoking cessation in middle and high school students who smoked or were ex-smokers. Method: Data were collected through focus group interviews with 3 groups (15 students), and were analyzed according to the analytic method of Morgan (1998) and Krueger (1998). Results: Six categories were identified. They included reasons to quit smoking, efforts to maintain smoking cessation, lures to start smoking again, improved self-esteem after overcome temptations, frustration following repeated failures in attempts to quit smoking and suggestions to help maintain smoking cessation. Through these results, it was found that reasons for quitting smoking were different from those of adults, strategies to maintain smoking cessation were limited and repeated failure in attempts to quit smoking led students to give up attempting to quit smoking. Conclusion: A high percentage of adolescent smokers want to quit but are unsuccessful in doing so. Considering the results of our analysis, smoking cessation programs and strategies should be carefully developed to be more effective in help adolescents quit smoking and maintain smoking cessation.

This study examined patterns of delinquent behavior trajectory from late childhood to early adolescence and examined relationships between patterns of trajectory and individual, family, and school factors. Youth delinquent behavior trajectories were examined by mixed growth models using data from the 2nd to 5th year surveys of the Seoul Panel Study of Children. Relationships between patterns and effect factors were examined by multinominal logit models. Four patterns emerged: non-delinquency (80%); rapidly accelerating delinquency (3.3%); decelerating delinquency (6.0%); and moderately accelerating (10.7%) groups. Contacts with a delinquent peer group had persistent effects on more serious delinquent behavior trajectories. Increased levels of self-esteem and school achievement prevented increase in delinquent behaviors; close relationships with parents and parental supervision caused decrease in delinquent behaviors.

This study explored social media use among 50 adolescents attending a public high school in a non-Western community. Adolescents participated in focus group interviews and completed a written self-report survey. Findings revealed that these teenagers use electronic communication forms such as phone texting and social networking sites to connect with friends and family. They show a preference for Facebook, YouTube, and Instagram, do not engage in risky Internet behavior, and acknowledge both positive and negative aspects of electronic communication forms. In addition, their selection of electronic communication forms is dependent upon several factors that include the strength of the relationship and type of discourse exchange. For example, they reserve phone texting and cell use, which are more private communication mediums for family and friends. Electronic communication did not replace face-to-face interactions; rather it complemented and extended those interactions. Findings support existing literature on adolescent social media use and those shared with other collectivist cultural groups.
