PURPOSE: The purpose of this study was to describe the effects of short term Schroth exercise on the Cobb angle, angle of trunk rotation (ATR), cosmetic appearance, and quality of life (QOL) in idiopathic scoliosis patients. METHODS: Five subjects with idiopathic scoliosis, (female, 3; male, 2) curvature type: thoracic, 2; lumbar, 3 underwent short term Schroth exercise for seven days. The exercise was performed for 3 h long sessions per day. The Cobb angle and QOL were measured before and after the intervention. ATR and cosmetic appearance were measured once. Sessions consisted of one baseline, seven intervention and three follow-up phases. The sessions were conducted with a one day interval. RESULTS: After the intervention, the Cobb angle was found to be significantly improve (p <.05), while the QOL did not differ (p>.05). The ATR showed decreased trends in the intervention phase. Data points during the intervention and follow-up phases showed a decrease in comparison with data points at the baseline, indicating that Schroth exercise might be effective in reducing the ATR and that these effects can be maintained after the intervention. Cosmetic appearance did not showed changed trends during the Schroth exercise intervention phase. CONCLUSION: Our results suggest that short term Schroth exercise may be valuable in improving the Cobb angle and ATR in patients with idiopathic scoliosis.

Interests in 3D virtual clothing technology and its application in online shopping malls are increasing with the advent of the Fourth Industrial Revolution. Most studies on 3D virtual clothing, however, are focused on observing drapes or ease of virtual clothing depending on fabric properties of representative clothing items. Therefore, the purpose of this study is: first, to determine if current input of typical material characteristics in 3D CLO are sufficient to formulate virtual skirts with different front and back silhouettes; second, to determine if subjective appearance evaluation matched physical shape characteristics of those skirts. In this study, appearances of typical cotton, wool, silk, rayon, and polyester skirts with different front and back pattern were compared between actual and virtual clothing depending on fabric materials. Subjective appearance evaluation was conducted by 7 experts regarding similarity between actual and virtual clothing with a 5-point scale. For objective evaluation of the both types of skirt shape, degree of roundness at the cross section, displacement of side seam, position of back waistline, and the number of folds at the skirt back were observed. In the case of cotton and wool, not the subjective appearance evaluation as well as shape characteristics of virtual skirts were well matched to the actual shape of skirts with a few material inputs. However, current material inputs for silk, rayon and polyester were insufficient to cover material differences in formation of virtual skirts with different front and back silhouettes.

This study aims to compare the ease of shirt patterns in the men's wear market that have been constantly developing, and to analyze the fitness and appearance through the 3D virtual try-on system. The study selected three industrial patterns and two educational materials of classic-fit and slim-fit shirts for a total of ten items. The experiments involved virtual wearing, a stress contact point perspective map, and appearance evaluations. First, the ease differed significantly in the chest, waist, and sleeve cap height according to the patterns. Second, based on the stress, contact point, and transparency, there was ease in the order of Nam, D-brand, J-brand, Park, and S-brand in the classic-fit shirts while the order of D-brand, Nam, J-brand, Park, and S-brand resulted in the slim-fit shirts. Third, in the appearance evaluation, higher points resulted in the order of J-brand, Park, S-brand, D-brand, and Nam in both classic-fit and slim-fit. The results showed that proper ease differs greatly by shirt-fit and target age. Also, the shirts with more ease tended to be evaluated less favorably in the appearance evaluation. Based on the results, the study suggests that the proper ease in chest circumference is 18cm for the classic-fit shirts and 6 cm for the slim-fit shirts.

The purpose of this study was to investigate if these factors affect the correlation between the female adolescent interest in appearance and appearance management behavior with self-concept and sexual maturity. To achieve this, a survey was conducted for the female students in elementary and middle school in the Seoul area. The results of this study were as follows. 1. The comparison of students' interest in appearance and appearance management behavior showed that the middle school students showed higher scores in both matters. 2. Elementary students generally held more positive self-concept, with domestic self value shown statistically high 3. Tanner Stage 2.3. the early puberty stage, for elementary school students, and Tanner Stage 3.4. the growth and development stage, for middle school students. The percentage of students who had already entered menstruating turned out to be only 33% for elementary students but 90% for middle school students. Their subjective views of sexual maturity were also different as elementary students had negative feeling when they thought their sexual maturity were maturity were earlier than their peers' while middle school students were just the opposite. 4. The study on the impact of self-concept and sexual maturity on the interest in appearance of female students in elementary and middle school showed that elementary students had a higher interest in appearance that corresponded to the lower domestic self-concept and a higher social self-concept. On the other hand, middle school students showed higher interest in appearance, corresponding to their higher social self-concept, lower domestic self-concept, more negative feeling of sexual maturity, and higher feeling of physical self-concept. The study on the impact of interest in appearance, self-concept, and sexual maturity on the appearance management behavior of elementary and middle school female students revealed that elementary students with a higher interest in appearance were more enthusiastic about appearance management. Middle school students' appearance management behavior turned out to be higher, corresponding to their higher interest in appearance, lower domestic self-concept, and higher social self-concept.

In this study, causes and consequences of bullying were explored, focusing on victim personality and appearance factors. The research model included the relationships among bullying, important causes of bullying (aggression, cleanliness, and obesity of victims) and consequences of bullying (self-esteem and depression) and was tested through survey data from 594 (194 male and 404 female) middle school students. Data were analyzed using descriptive statistics, confirmatory factor analysis, and path analysis with SPSS and AMOS. In the results of the model tests, victims who are more aggressive, less clean, and more overweight are more likely to be bullied. In addition, adolescents bullied by others tend to have lower self-esteem and more depression. Furthermore, the model comparison was assessed by gender and a difference between the two gender models was found. In the check of critical ratio for difference, it was concluded that the cleanliness of the victim is a more important cause of bullying for male adolescents than for female adolescents. It is meaningful to confirm the effects of the victim's appearance factors on bullying in the literature focusing on personality issues of victims. Educators and counselors may refer to the findings in developing counseling guidelines and manuals to prevent bullying in school.

Studies on Trapa of Korean, Japanese, and Chinese origins have been generally limited to currently living Trapa, thereby demonstrating the lack of phylogenetic approaches. In the present study, we conducted a numerical taxonomic study on 34 Korean origin Trapa species newly discovered in peat deposits. By using the numerical taxonomy as well as geological data, we created an appearance map based on the periods and taxonomic groups of the Korean Trapa. Further, by using this appearance map, we reviewed the limitations that exist in the taxa and simultaneously discussed the adaptational environment of Trapa in each period. Although other studies have discussed new variants of Trapa worldwide, including T. litwinowii V. vassil. var. chihuensis S.F.Guan & Q.Lang of China (Guan and Lang, 1987), the present study is significant because it provides data on the origin of Korean Trapa species. The availability of such data is essential in determining the adaptational environment of the presently living Trapa. To our knowledge, this is the first report of approximately 10 newly discovered and other presently living species of Trapa. Further, the appearance map in the present study allows the use of the 10 newly discovered species and variants of 34 Trapa species indigenous to South Korea for over 1000 years, for a comparison with the currently living Trapa species. Thus, the present study results could serve as important basic data to understand the adaptational environment of the genus Trapa. from the past to the present in Korea.

This study analyzed the difference between 2D image and 3D virtual clothing images based on stripe arrangement to obtain fundamental data for slim appearance. First, the slimming effect according to the three types of stripe ratio was examined. Subsequently, the slimming effects of seven types of one-piece dress designs according to the stripe location were analyzed. Subjective ranking was evaluated. The width items and radius of curvature were measured for the image's respective parts. Consequently, in 2D image and 3D virtual clothing images, the one with the narrowest stripe ratio was evaluated as the slimmest; however, the conditions for the slimming effect were different. In the seven one-piece dress designs, a difference was apparent in the ranking of the 2D image and 3D virtual clothing images. In the 3D virtual clothing image, arranging the stripes on the entire garment proved inefficient. The stripes were curved according to the curvature of the human body, creating an optical illusion that differed from that of the 2D image.

The purpose of this study is to provide basic data for the production of jackets with high fit by comparing and analyzing the adhesive and non-adhesive production methods of men's jackets. An analysis of the manufacturing method showcased differences between the adhesive and non-adhesive manufacturing methods in the cutting and wick attachment method, the shape and attachment method of the chest reinforcing wick, the sleeve attachment method, and the shoulder pad and sleeve reinforcing cloth attachment method. In evaluating the outfit, the overall fit of the shoulder, the fit of the chest, and the fit of the armpit were found to be high in the non-adhesive production method. In evaluating appearance evaluation, the front shoulder, chest, and sleeve overall appearance showed a high non-adhesive production method. Therefore, in order to increase the wearability of the shoulder pad and the the attachment method of the upper sleeve reinforcing cloth, the non-adhesive production method should be used, and in order to increase the overall wearability and armpit wear of the chest, the difference in the attachment method, and the reinforcement method of the armhole should be used. In addition, to increase the appearance of the jacket, non-adhesive production methods such as differences in wick attachment methods, shoulder pads, sleeve reinforcing cloth, and sleeve attachment methods should be used.
