This treatise deals with teen-agers' tendencies in selecting clothes, upon the recent liberalization measures of dress restriction. in regard to girl students' uniforms inmiddle and high schools, effective 1983. Results of my poll of 430 inquirees on the subject is outlined as follows; The surveyees have a preference for wearing box-style upper garments with a round-neck line and ribbon/tie collar. They also prefer to wear shirt cuffs mainly in set-in sleeve style. A straight skirt silhouetting the body line is anticipated to be longer in length than the knee line by 2 or 3 cm's. A dressy or sporty look would be most welcome, too. The ensemble of blue jeans and T-shirt blouse would be usual wear during school attendance. The reason why they like to choose trousers is considered to stem from the unisex look in fashion rather economical and practical purposes. Clothes material tends to be natural fabrics, single-colored and non-patterned. Color needs to be in a subdued mood, tuned with the same color and of neutral tint. In styling, emphasis is to be placed on femininity. In particular, the middle school girls wish to intensify 'Har-mony' in style while the high school misses are concerned with 'Individuality.'

This study was conducted to examine the relation between the clothing materials and the garment's ease under wearing condition. Wearing test of slacks in the same pattern which were made of 3 woven fabrics and 1 knitted fabric have teen carried out. Subjects were 5 female students. Some physical properties of these fabrics were investigated. The following results were obtained. 1, By analysis variance with the results of sensory test which was tested by paired com-parison method, it was obtained that the effect of materials on the garment's ease were significant at the $1\%$ level on every part of stacks and posture of subject. It indicates that there is a difference of materials from materials in garment's ease. 2. Significant at the $5\%$ level among the materials. Jersey and Jean were looser than the other two materials. Clothing materials have considerable effect on the garment's ease of slacks, therefore it was noticed that the ease of slacks must have considered the clothing materials. It is more necessary in working dress. 3. Elastic recovery of width was more contributive to garment's ease of slacks than any other physical properties.

This study provides the basic data for clothing construction of teen girls by researching and analyzing the characteristics of physical changes of tween generation school girls between 8 to 14 age. Fifty eight items of direct measurements and 61 calculated-items based on the 6th Korean National Physical Standard Reports were used. Results were obtained by using ANOVA, SNK test, coefficient of variation and growth rate of age groups. Significant differences were found among all the age groups, and were in the increasing order of height > length > width > depth > circumference. The growth rate was found in the increasing order of bust depth > hip width > N.P. to B.P. > hip circumference > bust circumference and thigh circumference. There were dramatic increases in height, circumference and width during the age of 8~9 and 10~11, in length during age of 10~11, and in depth during age of 8~11. The growth of the vertical measurement items is slowing at the age of 13. The individual differences were great in the vertical measurements at the age of 8 and 9 and in the horizontal measurements, at the age of 10. The increasing growth of bust and hip than waist gave it a curved shape.

Purpose: This review article provides an overview of the importance of breakfast by examining the relationship between breakfast and academic achievement including the papers published in Korean. Methods: This study searched a total of six domestic and international databases. The main search words for searching the database were 'breakfast,' 'morning meal,' 'adolescent,' 'teen or teenage,' 'children' and 'academic performance,' and used search operators when available such as 'breakfast AND adolescent AND academic performance'. Results: We searched a total of 274 studies through six databases and included a total of 15 primary studies in which 12 studies were cross-sectional and three were cohort studies. Since a quantitative integration of the primary studies was difficult to achieve such as performing a meta-analysis, this study performed a descriptive analysis of all the 15 studies and the results have shown that eating breakfast has a significant effect on academic achievement. In other words, students who regularly had breakfast showed more than twice the academic performance compared to those who did not have breakfast, and even though the math scores of students who had breakfast were statistically significantly higher, none of the study results inferred the reason. Conclusion: This study showed the importance of eating breakfast during adolescence by presenting that academic achievement increases with regular or more frequent habits of eating breakfast.

Charcot-Marie-Tooth (CMT) disease can be divided mainly into demyelination and axonopathy based on the results of the electrophysiological study. Mitofusin 2, encoded by MFN2 gene, has a crucial role in the fusion of mitochondria, which is known to associate with CMT type 2A as one of the axonal forms. We describe a 44-year-old man with progressive weakness on bilateral legs after noticing foot drop in his early teen. When we examined him at 45 years of age, he presented atrophy on entire legs and with distal muscle weakness on limbs. The nerve conduction study revealed severely decreased amplitude on motor nerve ranging from 0.2 to 4.5 mV, while conduction velocity remained more than 30.4 m/s. The whole-exome sequencing revealed a novel variant c.2228G>T in MFN2 by efficient genetic analysis tool, MutationDistiller. This report will not only expand the mutation spectrum of CMT2A but also introduce a time-saving genetic analysis tool.

The fourth Industrial Revolution, known as digital transformation, has made MZ generation to be the focus of the new consumer market, brought about the use of technological platforms a new consumption method. Currently, as various types of content collaboration are emerging that specifically targeting at the MZ generation. Content collaboration are considered an integration of content to create new values through co-existence and co-prosperity. This study identified the characteristics of collaboration of fashion brands from 2018 using literature and online news articles, and identified and classified through case studies of it determined movie content, game and virtual characters. By this research, it shown that collaboration with movie contents have increased the collaborative synergy by using the story in global media content. Collaboration with mobile games was generally used by young casual and sportswear brands. These brands which utilized characters from mobile games popular with to attract more teen consumers and strengthen brand awareness by adding values of high-technology and scarcity to the familiar images. In addition, collaboration with virtual characters has expanded value of the collaborative approach on expanding the range of advanced digital technology, from a promotional strategy during the distribution process through to the use of virtual models. As such, collaboration using the various types of content has developed beyond simple integration of identities among various areas, integrated products or brands that as a new value.

Black staining of the teeth in children and adolescents does not cause pain or serious illness, but it can be socially debilitating for esthetic reasons. Black staining is easily removed through periodic professional mechanical tooth cleaning and ultrasonic scaling, but it can easily recur within few months. Using essential oil-containing mouth rinses diluted at 50% twice per day could prevent the black staining from returning after it is removed, reducing the need for mechanical treatments and improving esthetics.

Purpose: This study was aimed at evaluating the effects of a smoking cessations health camp on levels of expiratory Carbon Monoxide concentration, self-efficacy, smoking knowledge and nicotine dependence among adolescents smokers. Methods: This research uitlized a one group pre-test post-test design. The smoking cessations health camp was developed after considering cognitive and behavioral aspects and was provided for two days and one night. The number of subjects was 31 high school students. Data were analyzed using descriptive analysis and paired t-test. Results: As compared to a pre-test, the average score of expiratory CO concentration and nicotine dependence were significantly lower and the average score of smoking knowledge was significantly higher in a post-test. An increase in the mean score of self-efficacy was not statistically significant. Conclusion: These results suggest that this smoking cessations health camp can provide teen smokers with the insightful antismoking information and an opportunity for anti-smoking practices. Therefore, this smoking cessations health camp can be effective and useful for adolescent smokers in other school settings.

Pleiotropic regulator 1 (PLRG1), a highly conserved element in the spliceosome, can form a NineTeen Complex (NTC) with Prp19, SPF27, and CDC5L. This complex plays crucial roles in both pre-mRNA splicing and DNA repair processes. Here, we provide evidence that PLRG1 has a multifaceted impact on cancer cell proliferation. Comparing its expression levels in cancer and normal cells, we observed that PLRG1 was upregulated in various tumor tissues and cell lines. Knockdown of PLRG1 resulted in tumor-specific cell death. Depletion of PLRG1 had notable effects, including mitotic arrest, microtubule instability, endoplasmic reticulum (ER) stress, and accumulation of autophagy, ultimately culminating in apoptosis. Our results also demonstrated that PLRG1 downregulation contributed to DNA damage in cancer cells, which we confirmed through experimental validation as DNA repair impairment. Interestingly, when PLRG1 was decreased in normal cells, it induced G1 arrest as a self-protective mechanism, distinguishing it from effects observed in cancer cells. These results highlight multifaceted impacts of PLRG1 in cancer and underscore its potential as a novel anti-cancer strategy by selectively targeting cancer cells.

Considering the continuous increase of teenagers' Internet use and the high rate of their participation in online communities, educators need to devote efforts to minimize the negative function of teenagers' Internet use and to guide them to experience positive aspects of Internet. Through activities in online communities, teenagers can experience various socialities and explore their self-consciousness. However, on the other hand many communities do not provide teenagers with considerate care. This may cause conflict in their sense of value and mislead them. Through this study, online learning community is designed and developed, which can reflect teenagers' various needs and connect their needs with learning experiences. The community consists of the following categories: 'about e-Tivity'(community vision, general information, list of activities, Q&A), 'activity space for teens'(event hall, data park, e-Tivity center), 'administrative space for teachers and managers'(research room, management room), and 'teen's private space'(my room, my avatar).
