Objectives: The prevalence of psychiatric disorders among young adults is different from that among younger or older age groups because of biological and environmental changes. The purpose of this study was to analyze the diagnostic distribution of psychiatric disorders in 19-30-year-old Koreans based on their age and gender using data from the Korean National Health Insurance Service (NHIS). Methods: From the 2011 medical claims sample data of NHIS of 1,375,842 people, we extracted the data of 221,038 people aged 19-30 years, including 106,232 (48.1%) men and 114,806 (51.9%) women. We evaluated the overall changes in the diagnostic distribution of psychiatric disorders over a 3-year period. Results: The diagnostic frequency in women was 13,627 (59.0%), which was significantly higher than that in men. "Other anxiety disorders" was the most common psychiatric disorder in both genders, followed by depressive episodes, somatoform disorders, "other neurotic disorders," and nonorganic sleep disorders. In men, attention-deficit/hyperactivity disorder or intellectual disabilities were not among the top 10 disorders. In women, no significant changes in major psychiatric disorders were seen over the 3-year period. Conclusion: These results reveal the trends of diagnostic distribution of mental illnesses depending on the development, particularly in young adulthood. It is necessary to identify whether such trends are due to biological or environmental factors, aging processes, or complex influences.

Purpose: This study was conducted to compare and analyze the smoking-related social-ecological factors affecting attempts to quit smoking by adolescents using tobacco cigarettes only and also those adolescents using tobacco cigarettes along with electronic cigarettes. Methods: This study, as secondary analysis research, used the raw data from the 14th Korea youth risk behavior survey 2018. The data was analyzed by frequency analysis, the Rao-scott χ²-test and logistic regression analysis when considering the complex sample's analysis. Results: On logistic regression analysis, during their first smoking period, intense physical activities and having friends who smoked were associated with significantly more attempts to quit smoking by cigarettes smokers, and their first smoking period and experiences of undergoing smoking cessation education were associated with significantly more attempts to quit smoking for dual smokers of both tobacco cigarettes and electronic ones. Conclusion: As a result of this study, we identified the need to differentiate different types of smoking cessation counseling and education according to the types of smoking in adolescents.

The weakening of the traditional cultures is becoming more evident from the final quarter of the last century, a period of time where the world starts to look like a "small village" in all means. A substantial cause of cultural deterioration shows to be the growing use of information and communication technologies widening the views, mentalities, and perspectives of people. Today the adolescent groups frequently owning, utilizing and consequently being charmed by the electronic equipment such like computers, internet and cellular phones have developed a unique tradition/practice in sensing and meaning life triggering larger generation gap and fading of established cultures. The main focusing of the paper is on the correlation between computer and internet use and life satisfaction, level of hope, personal development assessments and expectations of the adolescent groups in Turkey. Interpretation of the survey findings indicates that this group grading highest in use of that shows to be the happiest, most hopeful and optimistic ones among other groups. Methodologically, the study is based on data analysis and a review of recent key literature. For more dependable results a further study comparing similar tendencies of the similar groups of other nationalities is recommended.

Purpose: Adolescents who experienced the alcohol consumption have gradually increased. Adolescence is a critical period of the neural plasticity in the brain. Neural plasticity is mediated by neurotrophins and has an impact on cognitive function. Environmental enrichment ameliorates the cognitive function and increases neurotrophins. Thus, we investigated the neuroprotective effect of environmental enrichment on ethanol induced cognitive impairment in adolescent rats. Methods: The ethanol groups and the controls groups were injected with ethanol (0.5g/kg) and phosphate buffered saline, respectively, through intraperitoneal from 28th day of birth for 11 days. The environmental enrichment groups were provided larger cages containing toys than the standard cage. Passive avoidance test and Y-maze test were performed to evaluate the spatial memory. Results: Environmental enrichment+ethanol group showed higher alterations than the standard environment+ethanol group in Y-maze test (p<.05). In hippocampus, The environmental enrichment+ethanol group showed significantly higher level of the number of c-fos positive celsl and density of tropomyosin receptors kinase B receptor than the standard environment+ethanol group (p<.05). Conclusion: So, we suggested that the environmental enrichment played a role as a prophylaxis for prevention of memory impairment induced by ethanol exposure in adolescence.

Primary school is regarded as an important period when many health-related behaviors and life-styles begin to be formed. Acquiring them through school heath education has a strong influence on the health promotion of not only the family but also the community. The goal of this study is to provide baseline data to develop a suitable smoking prevention program for the first graders of middle school. In order to provide this baseline data, the relationships between knowledge and attitudes of the adolescent regarding smoking, and the degree of their stress and self-esteem of the adolescent were explored To achieve this goal a self-administered questionnaire was distributed to the students in two middle schools in Kwang-ju City by school nurses, 400 questionnaires were collected and analyzed using SAS-Fe. The findings were as follows; 1. The subjects of this study were 225 male and 179 female, their average age of than was 12.7. Two students were smoking currently and 49 students had smoked. They started smoking at the mean age of 10.0. 2. Students who were not smoking showed more positive attitudes regarding anti- smoking(F=34.07, p=0.0001), perceived less stress(F=8.32, p=0.0003), and had higher self-esteem(F=15.35, p=0.0001). 3. Those who had the intention to smoke in the future showed more negative attitudes regarding anti-smoking(F=38.97, p=0.0001), perceived more stress(F=4.87, p=0.002) and had lower self-esteem(F=5.55, p=0.0042) 4. Those who had a better self-perception of school performance showed more positive attitudes regarding smoking(F=8.28, p=0.0003), perceived less stress(F=3.48, p=0.0316), and had higher self-esteem(F=22.36, p=0.0001). Those who frequently communicate with their parent showed more positive attitudes regarding anti-smoking(F=4.27, p=0.0082), and had high self-esteem(F=13.28, p=0.0001). 5. There were positive correlations between the attitudes regarding smoking and the self esteem of the adolescent(r=0.36498, p=0.0001), and a negative correlation between the self esteem and the perceived stress of the adolescent(r=-0.34763, p=0.0001). From the above results, we notice adolescent's smoking were related not only with knowledge regarding smoking but also with the intention to smoke in the future, attitudes regarding smoking, and the degree of their stress and self-esteem. So the smoking prevention program to reduce adolescent smoking should include the strategies to increase self-esteem and to address the perceived stress and the dangers of smoking.

The film "The World of Us (2016)" shows the acquisition and loss of friendship that occur in the process of interpersonal shifts in latency school girls. Connection to the peer group helps compensate for the latency child's loss of parent-child intimacy and the ensuing feelings of loneliness. The protagonists realize that the relationship is not for retaliation or for victory, but for playing together. However the reality that lies in front of them will not be so easy. Watching this film reminds one of childhood.

This study was performed to determine the iron status of the adolescent Korean girls before and after menarche. The 101 subjects aged 11-13 years who attending in an elementary school in Mokpo were recruited. They were divided into pre-menarche (A) group or post-menarche (B) group based on their menstruation status. The latter subjects were sub-divided into one of the four groups according to the times of their menstruation B-I( $\geq$ 3 times), B-II (4-6 times), B-III (7-9 times) or B-W ( $\geq$ 10 times). In the total subjects, dietary iron intake, 11.3 mg/day, was below the Korean RDA for iron, the percentage of heme iron to total iron intake, 15%, and the bioavailability of dietary iron, 12.3%, seemed to be low. And their body iron storage, 140.8 mg, seemed to be insufficient. However, they tended to meet body's iron requirement in the cell level. Red blood cell number (RBC), hematocrit (Hct), and hemoglobin (Hb) level in the total subjects were 4.5 1012/I, 39.3%, and 13.0 g/㎗, respectively. The subjects in B group had lower (p<0.05) RBC and Hct compared to those in A group and the prevalence of iron-deficiency anemia tended to be high. Serum iron, ferritin, and soluble transferrin receptor (sTfR) and sTfR:ferritin ratio were 86.7 $\mu\textrm{g}$/d, 17.6 $\mu\textrm{g}$/l, 3.58 mg/1, and 230, respectively. Those four indices were not significantly different among the groups. The results of this study imply that, although there a tendency to affect negatively iron status, menstrual blood loss in adolescent females does not deteriorate obviously their iron status during the relatively short period up to 1 you. However, it should be better to improve their iron status after starting menarche by increasing iron intake, especially heme-iron, and enhancing factors for iron absorption.

Purpose: The goal of this paper is to offer practical suggestions for developing, implementing, and maintaining a successful school mental health program based on the model of a school mental health program for middle school students at the Namgu Hyosarang adolescent Mental Health Center. The model will be divided into six areas and the challenges and future direction of this program: creative approach to funding, creative staffing, education, training, needs assessment & resource mapping, collaboration and partnerships in a school mental health program, and developing an outcome evaluation research. Method: This is a descriptive study of the school mental health program model for middle school students of Namgu Hyosarang Adolescent Mental Health Center implemented over a four year period. Conclusion: Within this paper, a blueprint that can guide the development and implementation of school mental health programs has been offered. The actual application of this model will vary depending on the structure and goals of individual programs and schools. This model of our center has been identified as an effective school mental health program and the actual application program in regular learning times to middle school students. Establishing guidelines about the types of activities necessary for the successful implementation and sustainability of a school mental health program constitutes the first step in standardizing this process, and the school mental health movement continues to receive national recognition as a viable services delivery model for adolescents in need of mental health services. The recommendations outlined indicate that a school mental health program is more effective and necessary than the clinical service of a psychiatric hospital for adolescents' emotional/behavioral problems.

The search experience about dietary information had only 27.9% of subjects and search purpose was 'for homework'(33.3%) and 'for health'(32.0). The satisfaction degree of dietary information was not high. The connection motive to dietary information was mainly 'by site navigation casualty'(55.7%). Only 7.7% of subjects had experience of nutrition counseling using internet, and the motive of nutrition counseling was also 'by site navigation causally'(55.8%). The purpose of counseling was 'for diet'(41.5%) and 'for health problem'(30.2%), and the satisfaction degree of counseling result was very low. As the ask of improvement for counseling site were pointed out 'poor in answer content'(44.8%) and 'lazy answer'(31.0%). The subjects wanted to get the dietary information about 'growth in status'(41.4%), 'diet related skin beauty'(14.6%), the update period less 1 month, and the way of 'free board'(32.3%), 'game'(21.1%) and 'animation'(19.3%) as offer tool. The results of this study showed that although the internet using percent and frequency of subjects was high, they used dietary information very seldom and they are dissatisfied with internet nutritional information. Therefore, the information donor should consider which dietary information was needed and what is the optimal tool for adolescent.
