This study aims to offer basic data for consumer education regarding the use of mobile phones by adolescent consumers in a correct way by researching and analyzing the consumption value and consumption behavior of adolescent consumers for mobile phones to see how they use mobile phone as consumers, which is a serious of user behaviors according to their plan, purchase, use, and disposal. Based on the research results, the study proposes the following in relation to the correct use of mobile phones by adolescent consumers. First, in the purchase or use of mobile phones, a more demonstrative consumption pattern was more likely for males than females and for those who are in higher grades than those who are not. Therefore, it is necessary to offer consumer education given the gender and school year rather than stereotyped consumer education. Second, it is necessary to offer objective information and give consumer education for checking the instant desire for something new in order to prevent an impulsive purchase based upon advertisements given the characteristics of adolescent consumers who prefer new designs or functions. Third, regarding the disposal of mobile phones, it is necessary to seek strategies for recycling mobile phones usefully at an administrative level to prevent mobile phones from being thrown away without being recycled.

In recent years, adolescent issues including smoking, drinking, drug abuse, juvenile delinquency, deviant sexual behavior, mental health problems, high suicide rate, misconducts and absence without due notice, etc are emerging as serious social problems and the debate on these controversial issues is heating up. Accordingly, the purpose of this study is to analyze factors which are changeable and fixable among the factors influencing the adolescent's health behavior and misconducts and, eventually influencing factors which can be used as the basis to establish health policies and health promotion program to reduce the health risk behavior and misconducts of adolescents. The smoking rates are 34.1% for male students of prep schools and 13.8% for females students of the same school and 55.7% for males, 31.8% for females of the vocational schools and 58.3% for males and 48.8% for females of social institutional schools, which showed the great diffence among the different types of schools and between sex. In particular, male students of social institutional school showed 1.7 times higher smoking rate than those of prep schools and in case of female students, 3.5 times higher rate. The time of initial smoking was most frequently during the middle school days for both males and females. In case of drug abuse, 5.4% of males and 2.7% females of general schools were using adhesives and inhalants which was 2.5 times higher for males and 6.3 times higher for females of social institutional schools. 41.8% of males and 30.3% of females of prep schools, 41.8% of males and 59.4% of females of vocational schools and 55.1% of males and 36.6% of females of social institutional schools have experienced kissing. Regarding the health promoting behavior and misconducts, female students practiced the health promoting behavior more than male students while male students showed higher rate of health risk behavior and misconducts than female students, which was statistically significant. The group of students who have not attended the health education class, in comparison to those who have attended, were more likely to practice health risk behavior and misconducts. Those with higher academic achievement was more likely to practice the health promoting behavior while those with poor academic achievement were more likely to practice health risk behavior and misconducts. As the perceived health status was higher and as students experienced less illness, the health promoting behavior was higher.

The purpose of this study was to investigate the dietary habits, nutritional status, and serum copper and zinc concentrations of adolescent athletes. 50 high school adolescent athletes (29 male, 21 female) took part in physical education high school and 47 high school adolescent non-athletes (21 male, 26 female) in general high school. Questionnaires, anthropometric measurements, 24-hour dietary recalls and blood analysis were conducted. In the males, the mean height, weight and body fat percents of athletes and non-athletes were 174.0/172.9 cm, 67.4/68.3 kg, and 8.9/20.0% (p<0.001) respectively. In the females, the mean height, weight and body fat percents of athletes and non-athletes were 163.7/159.3 cm (p<0.01), 58.7/55.7 kg (p<0.05), and 18.6/30.1 % (p<0.001) respectively. In both male and female athletes, intakes of animal fat were significantly higher and intakes of vitamin C were significantly lower than those of non-athletes. There was no significantly difference in zinc and copper intakes between athlete and non-athlete groups. The average serum zinc level of male athletes was significantly lower than that of male non-athlete. The average serum copper levels of male and female athletes were significantly lower than those of male and female non-athletes. Based on these results, exercise may effect on zinc and copper utilization of adolescent. Further studies on zinc and copper nutrition of adolescent athletes were needed to understand more mineral nutrition and exercise.

This study examined the mediating effect of internal locus of control in the relationship between family and friend support and acculturative stress of North Korean adolescent refugees. Participants consisted of 101 North Korean adolescent refugees (40 males and 61 females) aged 13 to 24, who live in Seoul, Gyeonggi Province, and Busan. SPSS 25.0 and Mplus 5.12 were used to analyze data. Descriptive statistics and Pearson's correlation coefficients were calculated and structural equation modeling (SEM) examined the mediating effect. The results of this study are as follows. First, a higher level of family support and friend support were associated with a higher level of internal locus of control. A higher level of internal locus of control was associated with a lower level of acculturative stress among North Korean adolescent refugees. Second, the level of internal locus of control mediated the relationship between friend support and acculturative stress. This study is meaningful in that it examines the specific paths affecting acculturative stress of North Korean adolescent by examining family and friend support, which are environmental factors, and internal locus of control, which is internal factor of individuals. The study results suggest that improving friend support as well as increasing the level of internal locus of control for North Korean adolescent refugees can be an effective way to prevent or intervene acculturative stress.

Background: This study was undertaken to evaluate how gender differences affect the sensory processing by the Adolescent/Adult Sensory Profile(ASP) which evaluates the behavioral responses of adults to everyday sensory experiences. Methods: The study period lasted one month which was June 2009, and the study subjects were 325(three hundred twenty five) people who were healthy and reside in Chungcheong province including Daejeon. Detailed information about the study was explained to the study group and the ASP questionnaires were drawn up by them personally. Results: On average, the study group scores similarly in low registration, sensation seeking, sensory sensitivity, and sensation avoiding. According to the sensory processing abilities by gender, the group obtained scores indicating performance similar to most people in low registration, sensation seeking, and sensory sensitivity, except for sensation avoiding. Furthermore, in the taste/smell processing of "I only eat familiar foods", sensation avoiding score was higher in females than males, and in the activity level of "I find time to get away from my busy life and spend time by myself", males' sensation avoiding scored higher than females. Conclusion: In the study of differences of sensory processing abilities of adults by gender using the ASP, gender differences were revealed in the category of sensation avoiding.

Objective : There are few published studies which have documented psychopathological abnormalities in patients with of adolescent idiopathic scoliosis (AIS) The aim of this study was to evaluate the psychopathological influence of AIS in Korean 19-year-old males. Methods : The authors compared the Korean military multiphasic personal inventory (KMPI) military profiles of 105 AIS cases (more than 10 degrees of Cobb's angle without surgical treatment) with the KMPI profiles of 108 normal controls. The AIS group was split depending on Cobb's angle to further evaluate this relation by the severity of AIS. Results : A significantly decreased result on the faking-good response scale and an significantly increased result on the faking-bad response were observed in the AIS group compared to the control (p<0.012). The neurosis scale results, including anxiety, depression and somatization symptoms, were significantly increased in the AIS group compared to the control (p<0.010). The severity level of personality disorder and schizophrenia were also significantly increased in the AIS group (p<0.010). Differences in KMPI scale scores were not related to the severity of AIS. Conclusion : Young males with AIS tend to have abnormal results on the multiphasic personal inventory test compared to normal volunteers, suggesting that AIS may be related to psychopathology in the young male group in Korea. Although these psychopathology in AIS were differently observed compared to normal controls, but not interfered with military life. Clinicians are recommended to pay attention the psychopathological traits of patients with AIS.

Objectives: As a preliminary study on the prevalence of mental disorders in Korean children and adolescents, we investigated the diagnosis distribution of mental disorders in people under 19 years of age using the health insurance data. Methods: From the 2011 health insurance data of 1,375,842 people, the data of 286,465 people under 19 years old were extracted. Among them, we selected 10,778 with psychiatric diagnoses; male 6,453 (59.9%) and female 4,325 (40.1%). The frequency of psychiatric diagnoses in the males was 10,140 (62.7%) cases, which was significantly higher than that (6,031; 37.3%) in the females. We categorized the groups into 3 year intervals. Results: In the males under 3 years old, F80 was the most prevalent diagnosis, followed by F98. F90 and F41 were the most prevalent in the 4-15 and above 16 years old groups, respectively. In the females, F98 was the most prevalent in the children up to 3 years old, while F80 was the second most prevalent. In the 4-6 years of age group, F98 was the most prevalent, followed by F93. F90 and F41 were predominant in the 7-12 and above 12 years old groups, respectively. Conclusion: In the analysis of the frequency of diagnosis of mental disorders in the population under 19 years old, there were significant differences in the distribution based on age and gender.

Objective: To compare the electromyographic activity of masseter and temporal muscles between bruxers and nonbruxers in adult and adolescent patients. Material and Methods: The samples composed of the surface electromyography (EMG) recordings obtained from the orthodontic patients. Sixty-eight patients who had bruxsim habit (43 female and 25 male) were divided into four groups according to their age and gender. Control groups consisted of 79 patients who had not bruxism habit. EMG of the masseter muscle and anterior temporal muscle were recorded before treatment in clenching at maximum intercuspation. The ratio of temporal and masseter muscle activity (T/M ratio) was compared between bruxers and nonbruxers in adult and adolescent patients. Results: EMG of masseter muscle and temporal muscle were significantly higher in adult male bruxism group than control. T/M ratio in adult male bruxism group was significantly lower than in adult male nonbruxism group. However, there was no significant difference in T/M ratio between adolescent bruxism group and adolescent nonbruxism group. Conclusions: The balance in the activity of the masseter and temporal muscles may not differ between bruxers and nonbruxers during adolescent periods. However, in adult period, the masseter muscle activity against temporal muscle is greater in males with bruxism habit compared to non-bruxer.

Background: Work and work environment have a critical influence on adolescent workers' health. They are subjected to more risks than adults. The aim of this study is to examine psychological health outcomes in adolescent workers in the areas of depression, somatization, anxiety, hostility, and negative self-concept, and to investigate any related factors. Methods: This is a descriptive and cross-sectional study. Research samples were collected from adolescent workers between 15 and 18 years old attending a 1-day mandatory education course at vocational training centers, working 5 days per week in small enterprises. Data were collected using the following instruments: Brief Symptom Inventory, Multidimensional Scale of Perceived Social Support, and Descriptive Characteristics of Children's Assessment Form. Results: The investigation covers 837 young workers, of whom 675 were males and 162 were females. The majority of the families had low incomes (68.1%). Overall, 33.5% of the adolescents had been hospitalized because of health problems. Their average weekly working hours were $78.1{\pm}10.7$. Almost 50% of adolescent workers scored above the mean average in the Brief Symptom Inventory, indicating serious pschological health symptoms. Those who scored high for hostility, depression, negative self-concept, anxiety, and somatization were between 45.4% and 48.9% of the sample. Logistic regression analysis was conducted to determine the underlying factors: a perception of "feeling very bad" health conditions was 2.07-fold whereas the rate of "no annual leave" was 0.73-fold, and both were found to be effective on psychological problems. Conclusion: In this study, it seems likely that psychological health problems are the result of multiple adverse factors including working conditions, annual leave, and health considerations.

Objectives : This study investigated the differences between the psychiatric characteristics of minor juvenile offenders and normal adolescents as well as differences in psychiatric symptoms after a six month protective disposition. Further, the current study aimed at determining psychiatric screening methods for evaluating delinquent adolescents. Methods : The Latent Delinquency Questionnaire (LDQ), the Revised Children's Manifest Anxiety Scale (RCMAS), the Children’s Depression Inventory (CDI), the Reynolds Suicidal Ideation Questionnaire (SIQ), the Piers-Harris Children's Self Concept Inventory (SCI), and the Korean Youth Self Report (K-YSR) were administered to 134 normal adolescents (114 males) and 109 minor offenders (97 males) aged 12 to 16 years. After six months, 46 offenders (all males) completed the RCMAS, CDI, SIQ, and SCI again. Results : Adolescents with minor offenses had more delinquent, aggressive behavior and externalizing behavior problems, but were significantly less depressive, anxious, or suicidal than normal controls. Further, recidivists had more anxiety, depression, and delinquent behavior than non-recidivists. Minor offenders reported that their anxiety and depressive mood decreased after six months of protective disposition. Conclusion : Adolescents with minor offenses had more delinquent, aggressive behavior and externalizing behavior problems suggesting that psychiatric screening tools for minor offenders should measure disruptive behavior disorder.
