The purpose of this research is to identify the differences in appearance satisfaction, self-esteem and the feeling of happiness according to the demographic variables of teenagers. The conclusion of this research indicate that appearance satisfaction has significant impacts on the self-esteem and the feelings of happiness for adolescence. Teenage students who attend vocational schools get more Allowances than students who attend general high schools, and those who have parents with lower education level also get more Allowances. But the higher the economic standard and grades the students have, the more self-esteem and the feelings of happiness they possess. Thus, the students who attend general high schools have higher self-esteems and feelings of happiness than those in vocational schools. Additionally, the students who have higher economic standards and parents with better'- education levels show more appearance satisfactions for their face, skin and body. Therefore, the level of appearance satisfaction according to the types of school, economic standards, amount of Allowances and parents' education level is an important variable, which can also affect the self-esteem and the feelings of happiness. Teenagers' appearance satisfaction have a significant impact for determining the level of self-esteem and the feeling of happiness.

Objective: Stripe marks, which occasionally occur on the shell, do not cause breakage to the shell and shell membranes of eggs. This study investigated the quality of intact eggs (IEs), minor stripe-marked eggs (MEs), severe stripe-marked eggs (SEs), and cracked eggs (CEs) during 3-week storage at $25^{\circ}C$. Methods: Shell eggs were collected the day after being laid and were washed. Among them, eggs without any visual cracks or stripe marks on the shells were evaluated as IEs by the plant employees using candling in a darkened egg storage room; the remaining eggs exhibited some eggshell defects. At day 3, the eggs were further categorized into IEs, MEs, SEs, CEs, and broken eggs (BEs) on the basis of the description given. Except BEs, which were discarded, the remaining eggs were stored at $25^{\circ}C$ (approximate relative humidity 50%) and then analyzed. Results: Stripe marks were observed primarily within the first 3 days after washing. At day 3, CEs had significantly (p<0.05) lower Haugh unit values, but all eggs had grades AA or A, according to the United States Department of Agriculture standard. As storage time increased, differences in egg quality between groups were more obvious. IEs had the highest eggshell breaking strength. During storage, the total plate counts and pathogens, namely Escherichia coli, Campylobacter spp., Staphylococcus aureus, and Salmonella spp., were not detectable in the internal content of IEs and SEs. Conclusion: In conclusion, cracks degraded egg quality severely and minor stripe marks only slightly influenced the egg quality.

This study examined the relationship between homeroom teachers' transformational leadership, high school students' satisfaction in school life, and learning motivation. The researchers selected boys and girls' general high school as the target population and gathered survey data. The number of participants was 606; these were students from first and second grades. Questionnaires on teachers' transformational leadership, students' learning motivation, and satisfaction in school life were measured. T-tests showed the following: As a result of the analysis of the difference of transformational leadership, the average of the teachers with careers spanning over 15 years was statistically significantly higher than those whose career spanned over less than 5 years. The group which perceived the transformational leadership of the homeroom teacher as high showed higher motivation scores than the group with lower perception. The means were statistically significant in all the sub-variables. In school - life satisfaction, the average of the former group which perceived the transformative leadership of the homeroom teacher as high was significantly higher than that of the other group.

Objectives : Herniation of Nucleus Pulpous (HNP) of Lumbar is one of the most common causes of low back pain. The aim of this study is to investigate the effectiveness of acupuncture, bee venom acupuncture (BVA), and bee venom Pharmacopuncture (BVP) therapy for HNP. Methods : We separated 35 patients with HNP of L-spine into three groups; Acupuncture treated group, BVA treated group, and BVP treated group, and monitored for 30 days. 4 grades of recovery degree, score of Visual Analog Scale (VAS), and Oswestry Disability Index (ODI) were examined for comparison. Results : 1. Visual Analogue Scale of low back pain and radiating pain showed significant decrease in BVA and BVP groups compared to the Acupuncture group at VAS0_2, VAS0_3 evaluations. 2. ODI of disability of daily activities showed significant decrease in BVA and BVP groups compared to the Acupuncture group at VAS0_1, VAS0_2, and VAS0_3 evaluations. 3. Compared to the Acupuncture group, BVA and BVP groups were improved in S.L.R.T and R.O.M of L-spine as confirmed by the physical examination. 4. Treatment efficacy was more apparent in acute cases as ODI was significantly lower than chronic cases. Conclusion : BVA and BVP therapies can be used in addition to the acupuncture therapy for highly effective treatment of HNP. Further clinical studies are required to verify these findings.

Flux Cored Wire is the most widely used welding material for Flux Cored Arc Welding these days. This paper introduces the technical aspects of manufacturing FCW and the development trend of FCW for each type of steel and metal. The studies are ongoing to lower the production cost of seamless-type FCW since it has not been generally used in welding shops so far because of it high cost even though the seamless-type FCW has various advantages than folded-type FCW in terms of manufacturing technology. Meanwhile, a technical research has been carried out to develop a rutile type of FCW products which satisfies high toughness after post heat treatment. In addition, for high-speed fillet welding, there has been a development of welding materials which can be welded in Single Auto-Carriage 100 cpm or more and up to Twin Tandem 200 cpm without occurring any welding defect in order to improve the welding productivity. As Zn coated steel is being used recently to improve the corrosion resistance of the automotive parts, a research and development for Metal Cored Wire has been conducted to reduce the Si island produced in welding operation than those produced when using the former solid wires. A development of welding material that guarantees CTOD performance beyond $-40^{\circ}C$ CTOD to $-60^{\circ}C$ is underway by different steel grades, and FCW for super austenitic stainless steel is being developed as the corrosion resistant steel has been upgraded.

Body mass index(BMI) is recognized as one of the most useful indexes for adiposity in children and adults. This study was conducted to provide information on BMI distribution by age and sex in Korean children, and to identify sociodemographic factors that affected BMI among children. The study was conducted on 2376 children(boys 1184, girls 1192) living in a middle-size city in Korea. Subjects were selected from the primary schoolchildren in grades 1-6 using the two-stage sampling method. Their mean age was 9.4 years. The percentile of BMI tended to increase as age increased in both sexes. The 85th percentile for boys, aged 6-12 years, was 19.8kg/㎡, and the 95th percentile was 22.5kg/㎡. The 85th percentile for girls, aged 6-12 years, was 18.9kg/㎡, and the 95th percentile was 21.5kg/㎡. Multiple regression analysis was carried out to predict BMI from percent ideal body weight (PIBW), age and sex. After adjusting PIBW and age, BMI for boys was 0.062kg/㎡ lower than that for girls. One year of age increased BIM by 0.55kg/㎡. The prevalence rate of overweight and obesity based on PIBW was 15.8% and 15.0% for boys, and 14.0% and 11.0% for girls, respectively. Demographic factors such as sex, age, and parents' obesity influenced children's BMI. After adjusting for sex, age and parents' BMI, the presence of another children in family, and mother's employment status showed a strong effect on children's BMI. The results suggest an age-sex specific BMI distribution of Korean children. The present study also provides direct evidence of a correlation between early life environmental factors, such as presence of siblings or mother's employment, and BMI level in Korean children.

Purpose: This study was conducted to identify the factors affecting nursing students' attitudes toward nurse-physician collaboration. Methods: The subjects were 200 nursing students from a college in K city, and the participants were recruited by posting a recruitment announcement. Data were collected from June 26 to 29, 2018 and analyzed using SPSS 22.0 and descriptive statistics, t-test, ANOVA, Sheff? test, Pearson's correlation coefficients, and hierarchical multiple regression. Results: Attitudes toward nurse-physician collaboration showed a statistically significant difference according to grade, the reflection of opinion within the family, and the number of the counselor in general characteristics. Assertiveness and attitudes toward nurse-physician collaboration showed weak positive correlation (r=.18, p=.011). In hierarchical multiple regression analysis, the most affecting factor was junior grade (${\beta}=.25$), followed by positive assertiveness (${\beta}=.18$) and the number of the counselor (${\beta}=.14$). These variables explained 12.0% of the total variance in attitudes towards nurse-physician collaboration. Conclusion: To create positive attitudes toward collaboration between nurses and physicians in nursing students, various educational programs related to assertiveness on communication skills need to be provided from the lower grades. Also, a multidisciplinary simulation program should be developed and applied to be able to experience the situation of nurses and physicians.

This study examined mothers' perceptions on nutrition education for elementary school students according to demographical factors. Questionnaires were distributed to the mothers of 511 elementary school students in the Busan area. According to the results, 50% of the respondents felt that the preschool years or the lower elementary grades were proper times to start nutrition education. Furthermore, they preferred school dietitians (55.4%), outside professional dietitians (16.3%), nurse teachers (13.8%), class room teachers (11.7%), and parents (2.8%) as nutrition educators. The mothers who were college and university graduates had significantly (p<0.001) higher scores regarding the necessity of nutrition education for student growth when compared to mothers who were high schools graduates. However, the high school graduates had significantly (p<0.001) higher scores than the college and university graduates with respect to nutrition education for correcting obesity. The order of importance for nutrition education curriculum content was as follows: eating habits, food safety, health and disease, maintaining ideal body weight, food waste and environment, basic food knowledge, and traditional foods. The college and university graduates, and those of 'A' group schools, had significantly (p<0.001) higher importance scores for proper eating habits. Mothers having experience with nutrition education comprised 43.9% of the subjects, and there was a significantly (p<0.05) higher percentage of employed mothers as compared to unemployed. Eighty-six percent of the respondents wanted to receive nutrition education. For more effective learning, they preferred in-person group education rather than correspondence education using e-mails or printed materials from schools.
