This study analyzes the body shapes of lower-body obese female adolescents and proposes a slacks pattern suitable for their body type. Lower-body obesity is a prevalent type of teenage obesity, and our proposals aim to improve consumer satisfaction in ready-to-wear clothes across this demographic. We first observe characteristics of obese lower bodies, noting significantly above-average thigh and hip circumference. These figures indicate a high degree of curvature in obese lower bodies, along with a large drop value. Leveraging this data, we develop a novel slacks pattern using 3D avatars in a virtual simulation system. The formulas for the main areas of the pattern are as follows: front waist girth W/4+0.75cm+0.5cm, back waist girth W/4+0.5cm– 0.5cm, front hip girth H/4+1.25cm–0.5cm, back hip girth H/4+2cm+0.5cm, front crotch extension H/16+0.5cm, back crotch extension H/8+1cm. Results from appearance evaluations show that this pattern minimizes strain rate on the waist and hips, and its average score is significantly higher than that of an alternative pattern that was also evaluated. The minimized strain rate and high average score indicate that our pattern assigns a sufficient amount of space to the appropriate areas. Based on these results, we expect our research to inform slacks pattern development and production for obese consumers of all types.

The aim of this study to provide basic reference data for the development of video contents used in pattern drafting education and to explore the possibility of utilizing YouTube videos in such education. Subject videos were selected using the number of views. A total of 596 videos and 28 channels were analyzed for the period July to September 2019 and the results are as follows. With regard to content, there were 27 pattern drafting items, the majority being dress, pants, skirt, blouse and sleeve drafting, although high-level content such as cowl, bustier, corset patterns were also available. Therefore, there is a high likelihood that YouTube videos could be used as educational material, especially as supplementary references to provide specific examples and easy explanations for difficult concepts or method, for students majoring in this field. However, as most videos currently focus on a few items, expanding video content to features a wider variety of clothing items at different levels is necessary. With regard to video length, it mostly ranged from 10 to 15 minutes. It is not advisable to create lengthy lecture-style videos expounding on different principles or variations in pattern drafting when developing educational video material.

화산재의 확산은 심각한 사회적 문제를 야기한다. 화산재의 확산을 예측하기 위한 수치 분석은 시간이 걸리기 때문에 초기 대응에 필요한 정보들을 제공하기에는 부적절 하다. 이 연구에서는 시나리오 기반의 대상 기상장과 과거 기상장의 유사도를 분석하여 화산재 확산 정보를 제공할 수 있는 유사기상장 모델을 제안한다. 동아시아 지역 기상장을 분석하기 위하여 2005-2014년 WRF (Weather Research and Forecasting model) 데이터를 k-means 클러스터링 방법을 사용하여 분류하였다. 기상장 데이터의 수에 따른 정밀도를 확 인하기 위하여 2010년 1년치 클러스터링과 2005-2014년 클러스터링 결과의 최종 클러스터와 내부 원소들 사이의 상관계수 (correlation coefficient)와 유클리드 거리 (Euclidean distance)를 측정하여 비교분석 하였다. 1년치 결과의 경우 178 m의 평균 거리와 10년치 결과에서는 52 m의 평균거리로 95% 신뢰수준에서 유의하게 차이를 보여주었다. 모델의 정밀도는 기상장 데이터의 크기와 클러스터링 단 계가 증가함에 따라 높아졌고 기상장의 표준편차는 줄어들어 화산재 확산의 변동성이 감소할 것으로 나타났다.

The purpose of this study was to develop slacks patterns for obese-schoolgirls aged 10~12 by using a 3D virtual garment simulation system. The criteria for subjects in this study were girls who had a BMI of over 25kg/m2. A total of 155 schoolgirls who met these criteria were enrolled. The results were as follows: First, by using 3D virtual garment simulation, a new slacks pattern considerate of obese-schoolgirls was developed. The basic numerical formulae were as follows: Front and back hip girth of H/4－0.5+1 and H/4+0.5+1.5, front waist girth of W/4+1+0.5, back waist girth of W/4+2+0.5, front crotch extension of H/16－0.5, back crotch extension of H/8－0.5, front dart amount of 1, and back dart amount of 2. Second, according to the new slacks pattern appearance evaluation, the new slacks pattern scored more highly than the existing pattern for silhouette and ease amount, confirming that the new slacks pattern is appropriate for obese-schoolgirls. Additionally, the new slacks pattern was evaluated allowing for the proper space length of the waist, abdomen and hips. This study is expected to serve as important basic data for ensuing studies that may utilize a 3D virtual garment simulation system with 2D patterns and for future 3D pattern production program development.

The recent fashion market failed to satisfy the needs of female customers in their 30s who are demanding a slim jacket that makes the wearer look young and slim. Accordingly, the slim-fit jackets of domestic brands targeting the women in their 30s were collected to conduct look and movement fitting evaluations based on the standard somatotype, and a slim-fit tailored jacket prototype was developed based on the present findings. This research aims to increase the satisfaction level of the slim-fit jacket customers reflecting a variety of somatotypes of women in their 30s. The research process was developing jacket patterns fully reflecting the properties in terms of extra space and design lines for different somatotypes of women in their 30s based on the jacket pattern formulated through the advanced research, and then suggesting pattern design methods for the different somatotypes. In this sense, this research attempted to identify the problems concerning the slim-fit tailored jacket fitting for different somatotypes of women in their 30s. The main aim was to suggest ways to improve the customers’ satisfaction level regarding the fit, and enable the manufacturers to produce a well-fitting jacket reflecting the peculiarities of each somatotype.

The process of Apparel Product Development requires several major steps such as Pattern Digitizing, Grading, Marker Making, and Cutting Out. The current operation for Pattern Digitizing is conducted operators who amend apparel patterns on a computer after digitizing them based on a point-input method. The current process is laborious, time-consuming, and expensive due to error-prone work that leaves much to be desired in solution expansion. These studies develop an automated system for apparel pattern input based on vectorising technique. Supporting industrial standardization (the detailed targets for the system development) minimizes the involvement of operators and include: automatic recognition of pattern domain, automatic recognition of sample shape, and inner part recognition performing apparel characteristic function. The following picture shows an example using our system developed with a women bra pattern. Figure 2 represents women a bra pattern Figure 3 represents data implemented on the automated system we developed The results of our study : 1. Analytical speed: under 4 seconds in resolution 150 dpi, image size A3. 2. Length error: under 0. 2mm. 3. Outline: 100% extract of outlines cutting and marker pattern. 4. Pattern elements: classification automatically and editing available by user. 5. Pattern division: try one acting scanning various pattern. 6. Data entry/output: converting of DXF, AAMA, TIP, DIGIT. We developed an automated system based on vectorising software for implementation of apparel patterns. The cost of effective system repeatedly processes digitizing tasks with high quality in a few minutes. The system will contribute to the apparel industry field by implementing automatic steps for recognition and classification pattern.

The pattern cases for Korean traditional socks are named “beoseonbongip” which means a pouch to keep patterns for making “beoseon”. “Beoseon” is Korean traditional socks. This study is to identify characteristics of the pattern cases and to develop cultural products based on the unique characteristics of the pattern cases. One hundred fifty one photos of “beosonbongip” were collected and quantitatively and qualitatively analyzed. Seventy percent of them were made between Joseon Dynasty and 1960s. As a result, most of the collected pattern cases are rectangular and square shapes, red color, and silk fabrics, and sizes of them are from 9cm to 15cm. A few pattern cases with different sizes and colors were also observed. Most pattern cases were made by fixing two among four triangle pieces which made by folding four tips of a rectangular or square cloth and then puting a not or a loop on the remaining triangle pieces in order to open and close the pattern cases. In a small number of the pattern cases, three of the four pieces were fixed and a button, a bead, a broach, or two nots or two loops were put on the other piece for opening and closing. Products such as apparels, bags, pouches, frames, and key holders were made using “beoseonbongip” form and construction method. This shows that “beoseonbongip” is a useful motive for creative product development.

3D스캔-인체 및 의복 모델링-시뮬레이션-패턴 제작 및 검증의 전체 3D 의복제작 프로세스를 원활히 활용할 수 있도록 하기 위하여 3D 그래픽과 CAD 시스템 그리고 3D-2D 직접 패턴 전개 시스템을 이용해야 하는 데 이 때 장애가 되는 것은 3D 시뮬레이션한 가상의복으로부터 정확한 패턴을 추출하는 것이 어렵고, 전반적 과정의 호환이 쉽지 않다는 것이다. 이에 본 연구에서는 인체에 정확히 밀착된 부분과 드레이프가 있는 비대칭형 드레스를 대상으로 전체 프로세스를 원활하게 구동할 수 있는 방법을 모색하였다. 연구 방법으로는 3D 스캔 데이터를 이용하여 Maya로 범용성 3D 인체 모델을 만들고 이 3D 바디 모델에 맞는 3D 드레스를 디자인하고 모델링한 후, Rapidform, 2C-AN 프로그램과 YukaCAD를 이용하여 정확한 2D 패턴을 제작하는 과정의 호환성을 해결하며 진행하였다. 이 과정에서 도출한 패턴을 실제 의상으로 제작하여 착의 시킨 후 3D 의복 모델과의 여유분 분포를 3차원 측정 기술로 검증하였고 실물 드레스의 드레이프의 모양과 시뮬레이트된 드레스의 모양을 검토하였다. 그 결과 제시한 방법을 활용하면 전반적으로 만족스럽게 정량적인 3D 의복 제작 프로세스를 운영할 수 있음을 확인하였다.

Phospholipid hydroperoxide glutathione peroxidase (PHGPx) is a unique antioxidant enzyme involved in reduction of peroxidized phospholipids within biomembranes. To investigate the expression pattern of the PHGPx gene during fetal development, in situ hybridization analyses were performed using mouse FITC-labeled PHGPx cRNA probes in fetal tissues on embryonic days (Ed) 13.5-18.5. During these periods, PHGPx mRNA appeared in the developing telencephalon, diencephalon, spinal cord, and spinal ganglion. In particular, PHGPx mRNA was strongly expressed in pyramidal cells of the cerebral cortex. On Eds 17.5-18.5, PHGPx mRNA was detected in various tissues including liver, intestinal villi and crypt, pancreas, lung, and olfactory epithelium of the nasal cavity. In addition, PHGPx mRNA was highly expressed in the inner ear on Eds 14.5-18.5, brown fat on Ed 17.5, and adrenal gland on Ed 18.5. It is conceivable that PHGPx may act as an important antioxidant against fetal oxidative stress during mouse organogenesis.

For a good design, it is important to understand consumers and trend of textile and fashion design. Previous researches on textile pattern design with CAD have been done.

Therefore the purpose of study was to observe types of textile pattern design for the recent fiver years and determine fabric pattern trends, especially on the conversational motifs. The types of patterns were analysed with professional panels from the 2005～2009 collection sources, using SPSS program. This study was also develop textile patterns creating using CAD. We conducted design process on motif creating, repeat, and mapping jobs, using textile special design program Prima vision and Photoshop CS3.

The aim of this study was to develop a KDPS (Korean dietary pattern score) to assess dietary patterns and diet quality of Koreans from a food culture perspective. The KDPS was applied to dietary data collected during the Korean National Health and Nutrition Examination Survey of 2007, and the validity and reliability of the KDPS were evaluated. The targets of the study included 2,278 Korean adults aged 20n89 years. The KDPS was developed using the sum of the scores of 13 components. Each component scored up to 10 points and there was a total of 130 points. The first seven components were for the KSMS (Korean-style meal score) and assessed the dietary balance based on the 3-Chup Bansang daily basic table setting. The components numbered 8 to 13 were for the FGS (food group score), which measured the degree of compliance with the six major food groups based on the Korean recommendation for one serving size of grains, meats, vegetables, fruits, milk, and oils. This KDPS was verified through content validity, concurrent-criterion validity, principal components analysis, and a reliability analysis. The results showed that content validity and construct validity were high. The KDPS developed in this study adhered to the Korean dietary pattern and a healthy diet intake. Furthermore, this study presented an integrated index by scoring the Korean style table setting in addition to evaluating meals from a nutrition perspective. This study can be extended to develop a score for assessing.
