Objectives: Subjects of this study were technical high school students. It researched students' smoking status, smoking attitude, smoking perception and willingness to quit smoking, providing them with a five-day-smoking cessation program. Methods: Data collection proceeded from April to August 2008. The subjects were the whole number, 38 students, of 1EA technical high school located. The subjects who attended the smoking cessation program were the first and second grade students of the high school whom classroom teachers recommended. As to the subject, I comparatively analyzed differences between the before and after instruction, between after instruction and after consecutive consulting, and between before instruction and after consecutive consulting. The five-day-smoking cessation program took 2 successive hours a day for five days. Results: Average age for them to start smoking was 13.6 and to form smoking habits was 15.5. Average smoking period was 31.6 months and average smoking quantity was 11.2 cigarettes. As a result of the five-days smoking cessation program, 10.5% of the participants quit smoking and smoking quantity also significantly reduced. After instruction, willingness to quit smoking was generally higher than before. Smoking attitude, especially toward adolescent smoking, changed to be more negative than before. Perception of smoking also changed to be positive. Conclusions: The results from the comparative analysis of before and after instruction revealed a decrease on smoking quantity of the participants who attended the smoking cessation program. It also showed a significant change on smoking attitude, willingness to quit smoking and smoking perception.

'Adolescence' is a critical period in the process of growing and aging but important in that an adolescent becomes aware of and begins to look about him or her self. Especially with girls in their late teens (15$\~$18), they pay more attention to their looks and clothes than the boys do, which affects to some extent the formation of their personality and their behavior. From this point .of view. it is significant to establish the standard size of high-school girls' clothes. This study aims to measure high-school girls in size and to establish the standard size of their clothes; furthermore. to enable them to lead a satisfactory living with more appropriate size of clothes. The results, analyzed by two different representing items which resulted in little difference, are as belows: 1) Stature had a significant correlation with posterior waist height; bust girth had the most significant correlation with weight. and also some considerable correlation with other representing items; 2) The F-test result showed significant difference on $1\%$ level over all the items between the measured (Y) and the estimated (Y); the correlation among the representing items was considerable also; 3) When the measurement increases in stature by 4cm, bust girth by 4cm. and posterior shoulder width by 2cm respectively, the increase or decrease in other items are as shown on Table 4. Since this study was carried out in girls' high-schools in Seoul, it is expected to extend its further study throughout the nation. thus contributing to comprehending the whole truth of people's body-size and promoting the fabrication and modelling of the original clothes for the nation by the strict standard size up to making ready-made clothes with no difficulty in setting the standard and model size.

Purpose: The purpose of this study was to investigate the influencing factors on externalized and internalized problem behaviors among high school students. Methods: The subjects for this study were 707 students in two high schools in K province. The data were collected during the period from October to November, 2014 by use of questionnaires. The instruments used were the Korean Youth Self-report, Daily Hassles Questionnaire, State-Trait Anger Expression Inventory, and Ego Resiliency Scale. The data were analyzed using SPSS. Results: Significant predictors to explain externalized problem behaviors comprised anger-out, anger-in, anger-control, relation with parents, daily stress, and religion. It was found that these factors explained 46% of externalized problem behavior. Ego resiliency, anger-in, daily stress, gender, relation with parent, and anger-out were significant predictors to explain internalized problem behaviors. It was found that these factors explained 45% of internalized problem behaviors. Conclusion: This study suggests that the influencing factors on problem behaviors differ from externalized and internalized problem behaviors. So these findings will provide the basic data to develop a program that is differentiated by problem behavior type.

In cleft lip and palate (CLP) patients, there are various degree of residual maxillofacial deformities in adolescent period. Usually, orthoganthic surgery for the cleft patients needs Le Fort I osteotomy and/or mandibular set-back surgery. Previous report from other institute had been shown that there is significant relapse after maxillary movement after Le Fort I osteotomy when the surgical advancement of the maxilla was over than 5 or 7mm in average. Recent comphrehensive report showed that most of the relapse was happened within 1 year and the total horizontal relapse of the maxilla was as high as 30% in average. Therefore, overcorrection is needed in maxillary surgery for cleft patients. Another concerns for cleft orthognathic surgery is the anatomical variation in pterygomaxillary region in cleft patients compared to control patients. Patients with CLP had larger and thicker pterygomaxillary dimensions, and the results imply that careful attention to pterygomaxillary anatomy is needed in patients with CLP undergoing Le Fort I surgery. This article reviews the pre and postoperative considering factors for orthognathic surgery for CLP patients.

This study was conducted to compare the nutrient intake, physical characteristics, and health status according to daily fruits and vegetables intake of adolescents using the Korean national health and nutrition examination survey for the sixth period (2013~2015). Subjects were 1,096 adolescents aged 13~18 years. The average daily intake of fruits and vegetables was $518.49{\pm}4.94g$. The two groups (insufficient, sufficient) were divided by fruits and vegetables intake (<500 g/day, ${\geq}500g/day$) and the ratio of the insufficient group was 75.9% while that of the adequate group was 24.1%. The mean of intake of energy, calcium, phosphorus, sodium, potassium, iron, thiamin, niacin, vitamin C and dietary fiber differed significantly between the insufficient and sufficient groups (P<0.01, P<0.001). However, there was no significant difference in physical characteristics between groups. The self-perceived health status was better in the sufficient group (P<0.05), while the insufficient group was aware of more stress in their daily life (P<0.05). The serum triglyceride was significantly higher in the sufficient group (P<0.05), while the total cholesterol was lower (P<0.05). As the characteristics of fruits and vegetables are different, it will be necessary to determine standards for consumption of each type. It is also necessary to consider whether a fruits and vegetables intake of 500 g would be a reasonable standard for adolescents. Nevertheless, the results of this study indicate efforts to increase fruits and vegetables intake by young people are necessary.

Exercise and resveratrol supplementation exhibit anti-obesity functions in the long term but have not been fully investigated yet in terms of their early potential effectiveness. Mice fed with high-fat diet were categorized into control (Cont), exercise (Ex), resveratrol supplementation (Res), and exercise combined with resveratrol supplementation (Ex + Res) groups. In the four-week period of weight loss, exercise combined with resveratrol supplementation exerted no additional effects on body weight loss but significantly improved whole-body glucose and lipid homeostasis. The combined treatment significantly decreased intrahepatic lipid content but did not affect intramyocellular lipid content. Moreover, the treatment significantly increased the contents of mtDNA and cytochrome c, the expression levels of peroxisome proliferator-activated receptor gamma coactivator-1 alpha and its downstream transcription factors, and the activities of ATPase and citrate synthase. However, exercise, resveratrol, and their combination did not promote myofiber specification toward slow-twitch type. The effects of exercise combined with resveratrol supplementation on weight loss could be partly due to enhanced mitochondrial biogenesis and not to fiber-type shift in skeletal muscle tissues.

The health of feet is connected with individual's health and affects a man's activity. Shoes need to be designed to protect feet and to absorb the impact of land. In order to choose suitable shoes for feet, the foot size and shape must be considered, so it is essential to grasp the exact size and shape of the foot. This study aims to present fundamental data on shoes' easy order prototype development for choosing shoes of good wearing comfort, by classifying feet size and shape junior high school boys in the early adolescent period. The subject were 234 Korean junior high school boys age from 14 to 16 years old. The subjects were directly measured anthropometrically and indirectly analyzed photographically. 6 factors were extracted through factor analysis and those factors comprised 79.42% of total variance. The factors characterizing foot girth and width, foot length, foot height, foot shape around the fifth toes, angle of foot breadth and foot shape around the first toes. 3 clusters as their foot shape were categorized using 6 factor scores by cluster analysis. Type 1 was characterized by long large foot with deformed first toe. Type 2 had smaller in foot girth, width and length than other types and with deformed fifth toe. Type 3 had average size and high foot shape. Shoes prototype which is to be developed later on will be able to generate 2D flattening in the foot sole form. Therefore, it would be a great support in producing and choosing appropriate shoes if forms are classified by subdividing foot form classification and extract a factor which shows only the foot sole shape.

Purpose: This study was conducted to analyze the features of poisoning in individuals aged 0-18 years to understand the characteristics of potential victims and eventually prevent poisoning. Methods: We retrospectively analyzed poisoned children and adolescents (0-18 years) who visited the emergency department of one tertiary hospital from January 2003 through December 2013. We collected data including their age, sex, reason for poisoning, components and dose of poison, results of treatment, and psychiatric diagnosis. Results: During the study period, there were 436 cases of poisoning (male 47.2% (n=206); female 52.8% (n=230)). Subjects were classified into four groups (0-1 years, 2-5 years, 6-12 years, 13-18 years). The most common cause of poisoning in all age groups was accidental poisoning (72.9%), but intentional poisoning increased as age increased (p<0.001). Moreover, females were more often subject to intentional poisoning than males (p<0.001). The most common poisoning material was drugs (41.7%). Among intentional poisoning patients, 62.7% patients had consulted a psychiatrist, and their most common diagnosis was adjustment disorder (44.6%). Conclusion: The most common cause of poisoning in individuals aged 0-18 years was accidental poisoning, while intentional poisoning was most common among adolescents. Guardians should take care to prevent accidental poisoning, while psychiatric consultation and national moderation will be needed to prevent intentional poisoning.

In the present study, we studied the change patterns of adolescents' overt aggression during the middle school 2nd to the high school 1st grades and the effects of ecological factors on the change. For the research goals, we applied multi-level models to the Korean Youth Panel data. Results showed that adolescents' overt aggression decreased significantly during the period. Gender(males recoded as 1) and self-control had negative effects on the initial status(middle school 2nd grade) while the number of delinquency peers had a positive effect. On the other hand, gender and self-control showed positive effects on the change rate. The major strengths of the research are the study of various ecological factors and the longitudinal design. Few studies of adolescents' aggression have incorporated these methodological and substantive characteristics.
