  • The specific purpose of this study was as follows: 1) To identify the level of sexual awareness and demand for sex education of teenagers, their parents and teachers. 2) To investigate the attitude toward and acceptance of heterosexual friendships by teenagers, their parents and teachers. 3) To identify the experience and direction of sex education of parents and teachers. For this purpose, this study selected 341 male and female teenagers at three high schools located in a city, 119 parents with high school students and 243 elementary/middle/high school teachers. The structured questionnaire was distributed to each of them and returned by them. This study was conducted over the period between June 1. 2001 and Aug 31. 2001. A total of 720 questionnaires were distributed to them and 703 were returned. Data analysis was conducted to obtain percentage and frequency using the SAS program. As a result, the following findings were obtained: Parents and teachers showed a similar attitude about sexual awareness, but teenagers showed a different attitude. In terms of the level of feeling of and interest in 'sex', teenagers, parents and teachers were comfortable in accepting it. As for sexual curiosity in puberty, 84.8% of the parents and 95.5% of the teachers responded that it was natural, whereas only 14.7% of teenagers responded that it was natural. But As for the item that 'sex is natural as one of human needs', 3.6% of the teenagers, 16.8% of the parents and only 1.2% of the teachers responded that it was not. As for the item that 'A man has a stronger sexual impulse than a woman', 6.1% of the teenagers, 16.8% of the parents and 17.3% of the teachers responded that it was not. 64.2% of the teenagers and 90.2% of the teachers responded that it was impossible to overcome the sexual impulse, whereas only 8.4% of the parents responded that it was possible. As for the item of masturbation, 64.5% of the teenagers responded that it was possible for male students and not possible for female students. 67.2% of the parents and 91.1% of the teachers responded that it was possible regardless of sex. As for the item of an attitude toward virginal purity, both the parents and teachers showed that virginal purity was important for both man and woman, but teenagers showed a weak awareness of virginal purity. As for the item, 'It is possible to have sexual intercourse with a lover during adolescence', 20.2% of the teenagers, 79% of the parents and 87.7% of the teachers responded that it was impossible. As for the item 'It is necessary to keep premarital virginal purity for a happy married life', 21.1% of the teenagers, 74.8% of the parents and 55.1% of the teachers responded that it was necessary, which shows that teenagers had a different opinion than parents and teachers. In case of pregnancy in adolescence, most of the responding teenagers, parents and teachers chose abortion. As for the item 'female refusal on male sexual approach', respondents accepted female refusal as they did for orders of teachers, parents and adolescents. As for item 'An assaulter is entirely to blame for sexual assault', all of three groups responded in the affirmative.

  • Purpose: Obesogenic environments in children, in particular excessive intake of sodium, generate hypertension, which is a major risk factor for chronic diseases. Methods: In all, 725 children, 379 boys and 373 girls, aged 8~9 years were recruited from seven elementary schools in Kuro-ku, Seoul. To evaluate whether or not obesity risk was modulated by salt-sensitive genes, Solute Carrier Familiy 12 member 3 (SLC12A3) was used as the target. After children were assigned into obese (BMI > 85 percentile) or non-obese groups, anthropometry, blood biochemistry, and dietary intakes were measured according to the genotypes GG (wild) or GA+AA (hetero+mutant). Results: Without gender differences, high TG and low HDLc were detected in the obese group compared to the non-obese group. Regardless of obesity, weight gain and blood pressure (BP) increased in the SLC12A3 GA+AA genotype rather than in the GG type. HDLc was associated with obesity risk without genotype difference. Odd ratios for risk of obesity were 15.57 (95% CI 2.192~110.654), 22.84 (95% CI 1.565~333.469), and 9.32 (95%CI 1.262~68.817) in boys and girls with GA+AA genotypes as sodium intake increased above 4,000 mg/day. Dietary calcium, sodium, folate, and vit C were associated with obesity risk according to gender or genotype differences. Since high folate intake reduced obesity risk in only boys with GG type. Risk for overweight and obesity increased in boys with GA+AA genotypes and dietary habits with high sodium and cholesterol and low folate. Conclusion: The A allele of SLC12A3 rs11643718 was sensitive to development of obesity in children as sodium intake increased.

  • The purpose of this study was to examine whether self-differentiation mediates the relationship between adolescents' family functioning and self-esteem and to examine whether peer support and family conflicts had moderated mediating effects. For this purpose, 522 students from four high schools in Gyeonggi province were surveyed about their family functioning, self-differentiation, self-esteem, and peer support. The results were analyzed using SPSS 21.0 and PROCESS. The mediating, modulating, and moderated mediating effects were analyzed. The results of this study were as follows. First, correlation analysis showed that family functioning, self-differentiation, self-esteem, and peer support were significantly positively correlated. Second, the moderated mediating effects of peer support were as follows. First, self-differentiation had a partial mediating effect in the relationship between family functioning and self-esteem such that family functioning and self-differentiation were positively correlated and self-differentiation and self-esteem were positively correlated. Second, peer support had a moderating effect in the relationship between family functioning and self-differentiation that promoted self-differentiation. Thus, peer support affected family functioning and self-differentiation. Third, verifying the moderated mediating model of peer support by combining the mediation model of self-differentiation and the moderation model of peer support identified above showed that self-differentiation mediated the relationship between family functioning and self-esteem. Thus, family support affected self-differentiation and self-differentiation affected self-esteem. The significance of this study was as follows. First, it showed that self-differentiation significantly mediated the relationship between family functioning and self-esteem, clarifying the relationship between family functioning and self-esteem. Second, it showed that peer support moderated the relationship between family functioning and self-differentiation, identifying a mechanism that promotes self-differentiation. Third, it showed the mediation of self-differentiation of the relationship between family functioning and self-esteem depended on peer support.

  • This paper discuss adolescent's a quality of life related with risk behavior. The purpose of this study investigate to influence on risk behavior(runaway, smoking, sexual behavior) of the protective factors that moderate adolescent's problem behavior(delinquency). The assumption of this study that the protective factors counterbalance the negative influence of risk factors and finally, diminish a the problem behavior including a delinquent. A total of 1,020 students of a vocational high schook and a 216 adolescents of a special groups(the public institution that consisted with a delinquent young man) completed the questionnaires(risk behavior, 5 protective factors) of compiled by this researcher. The protective factors have selected based on the various prior studies analyzed with adolescent's risk behavior a family functioning, a father(a mother) each and child communication, a self efficacy, and a social support. Statistics appled for the data analysis are Chisqure analysis, two-way ANOVA, and Standard Discrimination analysis. The results of this study are as follows. First, the special group is higher than the general group in the rate of runaway, smoking, and sexual deviant behavior. Second, the protective factors are not action in the special group have experienced delinquency, but are only action in the general group consisted with the students of a vocational high schools. This means that the protective factors discriminating the participation of the risk behaviors, and blocking out the intervention of a problem behavior in the general adolescents. Although each protective factor influence to different according to each risk behavior, a role of a parent-child communication, a family functioning, and self-efficacy high orderly. Finally, discussed based on the previous studies that the protective factors moderate the negative influence of risk factors, offset the connection between a risk behavior and a. problem behavior, and improve and a resilience and the quality of life of the adolescents.

  • Purpose: The purpose of the study was to analyze the status of dietary behavior and nutrition intakes according to the gender and the level of physical activity of adolescents. Methods: Data from 659 adolescents aged 13 to 18 years who participated in the Korea National Health and Nutrition Examination Survey (2017-2018) were analyzed. Collected data were analyzed using complex sampling data analysis with SPSS v. 27.0. Results: The adolescents were categorized into three groups based on their physical activity as follows: The first group with high physical activity (8.9%), a second group with normal physical activity (29.7%), and a third group without physical activity (61.4%). Boys showed significantly higher physical activity than the girls. Adolescents with high physical activity had a significantly lower body mass index than adolescents without physical activity, but their meal regularity, subjective health status, and recognition of body image were significantly higher. In terms of biochemical factors, adolescents with high physical activity had lower triglycerides and cholesterol than adolescents without physical activity, while hemoglobin and hematocrit were significantly higher. In addition, the intakes of energy, carbohydrates, proteins, fat, vitamin B1, niacin, calcium, phosphorus, sodium, potassium, iron increased significantly as adolescents' physical activity increased. Conclusion: The physical activity of adolescents had a positive effect on dietary behavior, lifestyle, and nutritional factors. Therefore, it is necessary to increase participation in physical classes in schools and develop various programs considering the level of physical activity among adolescents.

  • Objective: This study aims to measure cognitive load levels by analyzing the EEG of Koreans and foreigners, when they read a Korean text with care selected by level from the grammar and vocabulary aspects, and compare the cognitive load levels through quantitative values. The study results can be utilized as basic data for more scientific approach, when Korean texts or books are developed, and an evaluation method is built, when the foreigners encounter them for learning or an assignment. Background: Based on 2014, the number of the foreign students studying in Korea was 84,801, and they increase annually. Most of them are from Asian region, and they come to Korea to enter a university or a graduate school in Korea. Because those foreign students aim to learn within Universities in Korea, they receive Korean education from their preparation for study in Korea. To enter a university in Korea, they must acquire grade 4 or higher level in the Test of Proficiency in Korean (TOPIK), or they need to complete a certain educational program at each university's affiliated language institution. In such a program, the learners of the Korean language receive Korean education based on texts, except speaking domain, and the comprehension of texts can determine their academic achievements in studying after they enter their desired schools (Jeon, 2004). However, many foreigners, who finish a language course for the short-term, and need to start university study, cannot properly catch up with university classes requiring expertise with the vocabulary and grammar levels learned during the language course. Therefore, reading education, centered on a strategy to understand university textbooks regarded as top level reading texts to the foreigners, is necessary (Kim and Shin, 2015). This study carried out an experiment from a perspective that quantitative data on the readers of the main player of reading education and teaching materials need to be secured to back up the need for reading education for university study learners, and scientifically approach educational design. Namely, this study grasped the difficulty level of reading through the measurement of cognitive loads indicated in the reading activity of each text by dividing the difficulty of a teaching material (book) into eight levels, and the main player of reading into Koreans and foreigners. Method: To identify cognitive loads indicated upon reading Korean texts with care by Koreans and foreigners, this study recruited 16 participants (eight Koreans and eight foreigners). The foreigners were limited to the language course students studying the intermediate level Korean course at university-affiliated language institutions within Seoul Metropolitan Area. To identify cognitive load, as they read a text by level selected from the Korean books (difficulty: eight levels) published by King Sejong Institute (Sejonghakdang.org), the EEG sensor was attached to the frontal love (Fz) and occipital lobe (Oz). After the experiment, this study carried out a questionnaire survey to measure subjective evaluation, and identified the comprehension and difficulty on grammar and words. To find out the effects on schema that may affect text comprehension, this study controlled the Korean texts, and measured EEG and subjective satisfaction. Results: To identify brain's cognitive load, beta band was extracted. As a result, interactions (Fz: p =0.48; Oz: p =0.00) were revealed according to Koreans and foreigners, and difficulty of the text. The cognitive loads of Koreans, the readers whose mother tongue is Korean, were lower in reading Korean texts than those of the foreigners, and the foreigners' cognitive loads became higher gradually according to the difficulty of the texts. From the text four, which is intermediate level in difficulty, remarkable differences started to appear in comparison of the Koreans and foreigners in the beginner's level text. In the subjective evaluation, interactions were revealed according to the Koreans and foreigners and text difficulty (p =0.00), and satisfaction was lower, as the difficulty of the text became higher. Conclusion: When there was background knowledge in reading, namely schema was formed, the comprehension and satisfaction of the texts were higher, although higher levels of vocabulary and grammar were included in the texts than those of the readers. In the case of a text in which the difficulty of grammar was felt high in the subjective evaluation, foreigners' cognitive loads were also high, which shows the result of the loads' going up higher in proportion to the increase of difficulty. This means that the grammar factor functions as a stress factor to the foreigners' reading comprehension. Application: This study quantitatively evaluated the cognitive loads of Koreans and foreigners through EEG, based on readers and the text difficulty, when they read Korean texts. The results of this study can be used for making Korean teaching materials or Korean education content and topic selection for foreigners. If research scope is expanded to reading process using an eye-tracker, the reading education program and evaluation method for foreigners can be developed on the basis of quantitative values.

  • This study is a descriptive comparative investigated one to analyze nursing education system and curriculum of Korea and China trans-culturally. 1) Education System The basic level of nursing education in Korea consisted of 65 3-year- junior college of nursing (7379 students) and 48 4-year-bachelor of nursing college (2345 students) in 2000 showing more 3-year-junior college of nursing and its students. In China, western nursing as well as Chinese nursing education system were operating. In 2000, 501 western school of middle technical nursing, 29 school of middle technical nursing of middle level education, and 89 3-year western and 24 Chinese junior college of nursing, and 42 4-year western bachelor of nursing college and 10 Chinese of high level education have been established. The presence of Chinese school of middle technical nursing system seemed to be in slower development in nursing than Korea, but that of Chinese nursing education seemed to be advanced with its national identification prior to Korea. Post graduate continuous education for RN-Diploma and RN-BSN program has been opened as in Korea. The Hosa(護士) system in school of middle technical nursing in China reflects lower level of education than Korea. But it can be a merit, other than in Korea, without nurses aids, when they are acting under supervision of nurses and led by them, and there presents a special course for promotion up to high level education. Graduate school in Korea is divided into general type opening a curriculum for MS in 1960 and as of 2000, 21 general types for majoring in nursing. The PhD course in Korea was established in 1978, and after that the PhD courses have been opening in 14 universities at present. China established master degree course in 1991 and as of 7 colleges are ongoing, and the doctoral course is now under planning, resulting slower development than Korea. 2) Education of theory and clinical practice in Korea and Chine (1) Korea's 3-year junior nursing college have 51 subjects, 49 subjects in China, which was not different. China was following education of ideology and medical. 4-year Bachelor of Science College has 92 subjects in Korea with cultural subjects and essential major studies/elective in theory education in Korea, while 63 subjects in China, showed wider selection in Korea's education. (2) Korea's 3-year and 4-year nursing colleges performed clinical practice education parallel with theoretical education for a certain period, block or theory/practice system. While China's 3-year and 4 or 5-year-colleges educated the theory first and then practice for one year in the last grade, integrating each situation of the departments and the theory. (3) Korea's oriental nursing theory in nursing education was performed in 28 colleges of 65 nationwide ones of 3-year junior nursing colleges, but only one school was educating clinical practice. In 4-year bachelor of nursing colleges, the oriental nursing theory was done in 14 among 48 investigated. And 1-4 subjects of them were doing, and 4 schools performed of clinical practice, showing more reinforced than the junior colleges. China's 3-year and 4-5-year western nursing colleges taught two subjects of Chinese medicine nursing. China's 3-year & 4-5-year College of Chinese medicine nursing, theory of Chines medicine nursing education taught eight subjects. (4) 5-year colleges of Chinese medicine western integrated nursing, theory of Chinese medicine nursing education consisted of twelve Chinese medicine nursing subjects and two of Chinese medicine western integrated nursing subjects. China was tempting a new development of a pattern of Chinese medicine nursing subjects reinforced. 3) The verification of Korean and Chinese nurse's license. The verification test of Chinese nurses license is differentiated at the level of education other than in Korea. Expire date is 2 years and a qualified test must be done to a renewal. And the continuing education hours are 72 per year, which is more enforced than Korean nurses (10 hours a year). In accordance with WTO regulations, we should prepare for opening foreign hospital, educating oriental nursing subjects. And on this, it is recommendable to settle a basic frame research to run the oriental nursing practice ongoing. 1. It is desirable to develop the oriental nursing subjects to apply its idea to the western nursing and differentiate Korean nursing. 2. It is desirable to certify oriental nurse's characters, to expand and develop the nursing areas to practice it, and to establish the oriental nursing system. 3. It is expectable to promote Korean nursing specialization to develop the oriental nursing as a professional and to create its demand.

  • In a highly competitive marketplace, U.S. retailers are challenged to attract, recruit, and retain a skilled workforce. The purpose of our research was to examine the impact of young retail employees' work experiences on their job performance, job satisfaction, and career intention using a comprehensive approach to model development. The model was developed in three phases over a four-year period using both qualitative and quantitative methodologies. During Phase 1, we conducted focus group interviews to guide the development of the questionnaire. Work experience was initially operationalized as role conflict, role ambiguity, supervisory support, and work involvement. Using a student sample(n=470) from U.S. universities, we employed multiple regression to determine the significance of relationships between their work experience, job satisfaction, and retail career intention. During Phase 2, we expanded our investigation to include retail work experiences of teens employed while they were in high school. The teen sample(n=898) was drawn from students enrolled in work-study programs in 16 U.S. high schools, and data were analyzed using structural equation modeling (hereafter SEM). During Phase 3, we expanded our model to include two new variables, job characteristics and job performance. Based on a national sample(n=803) of U.S. university students, we employed SEM to holistically determine if retail employees' work experience impacted their job performance, job satisfaction, and retail career intention. During each phase, job satisfaction consistently was the superior antecedent of retail career intention. Among the work experience variables, supervisory support had a positive impact on job satisfaction, while role conflict, role ambiguity, and work involvement exhibited inconsistent effects on job outcomes. The strong relationship between job satisfaction and retail career intention should make job satisfaction a priority for retailers.

  • Purpose: The aim of this study was to estimate total sugar intake and sugar intake-related dietary habit and nutrient intake of elementary school students. Methods: Subjects included 701 elementary school students (351 boys and 350 girls) residing in Jeju. The research analyzed a sample and was carried out using the 24 hour recall method and one day consumption of total sugar. Results: The average daily total sugar intake was 55.3 g (male 53.1 g, female 57.6 g). Total sugar intake per meal was 6.3 g (11.4%) from breakfast, 6.9 g (12.5%) from lunch, and 7.2 g (13.0%) from dinner, 34.9 g (63.1%). Major food groups of total sugar were milks (17.04 g), grains and their products (12.79 g), fruits and their products (9.40 g), and sugars and sweets (7.30 g). In analysis of the amount of total sugar consumption from several recipes, much was taken in from dessert and snacks such as dairy products (15.08 g), bread and snacks (6.4 g), beverages (5.5 g), fruits (5.1 g), and ice cakes (4.8 g). Total sugar consumption was high for rices and side dishes such as noodles (5.1 g), stir-fried foods (2.3 g), fried foods (1.4 g), cooked rice with seasoning (1.4 g), and hard-boiled foods (1.1 g). In comparison of total sugar consumption for sugar sources, daily intake of natural sugar, added sugar, and natural and added sugar were 25.8 g, 23.3 g, and 6.2 g, respectively. High sugar intake group, which was over 20% of the energy from total sugar intakes, consumed significantly less Fe, Zn, and niacin than the low sugar intake group, which was below 20%. Conclusion: Total sugar intake of fifth graders of elementary schools on Jeju Island was 55.4 g/day, and it was usually intake from snacks. Therefore, elementary school students need nutritional education for proper selection of better snacks and for reduction of dietary sugar intake.

  • Objectives : The purpose of this study was to provide some basic data for effective prevention and oral health education for oral health. For that purpose, a self-administered questionnaire was distributed to the boys of three high schools in Gyeonggi Province. Methods : The questionnaire consisted of items about the practice of oral health control and knowledge of decay according to grade, number of snacking, preferred taste, and toothbrushing. Total 487 questionnaires were put to analysis using the SPSS WIN 13.0 program. Results : 1. The biggest number of the boys brushed their teeth twice a day. The 10th graders brushed teeth three times a day, and the 11th and 12th graders tended to brush teeth twice a day(${\chi}^2$=18.21, p<.05). 2. As for the way of toothbrushing, 39.0% of the boys said they brushed teeth the way they felt like, being followed by those who said they brushed teeth turning the toothbrush up and down and brushing both the teeth and gums(32.6%). As for the number of snacking, those who had snacks three times a day or more brushed teeth turning the toothbrush up and down and brushing both the teeth and gums. Those who hardly had snacks more tended to brush teeth the way they felt like than those who had snacks(${\chi}^2$=21.28, p<.05). And as for preferred tastes, those who preferred a sweet and salty taste more tended to brush teeth the way they felt like than others. And those who preferred a hot taste brushed teeth turning the toothbrush up and down and brushing both the teeth and gums(${\chi}^2$=26.85, p<.01). 3. The respondents' percentage of correct answers for 'Decay is caused by bacteria' was 81.5%. Those who preferred a hot taste recorded the highest percentage of correct answers(${\chi}^2$=21.95, p<.00). 4. Their percentage of correct answers for 'Decay is accompanied by pain from the beginning' was 78.2%. The 12th graders had the highest rate of correct answers, and the 11th graders had the highest rate of wrong answers(${\chi}^2$=11.56, p<.00). 5. Their percentage of correct answers for 'Fluorine is helpful to the prevention of decay' was 75.4%. Those who hardly had snacks recorded the highest rate of correct answers(${\chi}^2$=10.05, p<.02). 6. Their percentage of correct answers for 'There is a way to supply fluorine into the waterworks' was 29.2%, which means the percentage of wrong answers was much higher. The percentage of wrong answers was the highest in the 11th grade(${\chi}^2$=7.06, p<.03). 7. The respondents' mean scores of knowledge of decay were 13.15 of total 18. While the 12th graders showed the highest level of knowledge of decay, the 11th graders were lower in the level of knowledge of decay than the other graders. And there were significant differences(F=5.41, p<.01) according to grade with no such differences according to the number of snacking and preferred taste. Conclusions : Oral health education should be applied to the boys all through their life to have a great effect, and it is important that they should always put the oral health education into practice to be a successful education.
