To understand the basic relationship between 3D curved surface model and 2D pattern, simplified torso model was generated by commercial CAD program (IDEAS). 3D torso model was then divided into different blocks and unfolded into a flat pattern as in ordinary works of clothing item design. As results, 2D pattern development of different part of 3D torso model was attempted and analyzed mathematically. It was found that different height, radius and tangent slope of 3D blocks resulted in different 2D pattern. The relationships between the shape parameters of 3D torso blocks and those of 2D patterns were analyzed using regression equations. Direct way of drawing a 2D pattern of corresponding 3D torso block was also illustrated for the convenience of pattern making using conventional measurements of upper/ lower radii and height of 3D torso block.

The purpose of this study is to develop a torso pattern that is highly representative for the proper body shape of women in their thirties. Size data of the women with age of 30 through 39 from the database of Size Korea 2004 were used for the study. In order to develop a master pattern which will be used as the benchmark for grading of research group, 4 existing torso block drafting methods were compared based on the data gathered and the block with the highest evaluation score was utilized as a reference point. For the analysis, data was divided into four types, only the data of 138 subjects which were evaluated at least by four or more experts as valid were used for the study. The major results can be summarized as follow. The women of bust girth of 91cm and height of 160cm which was turned out to be representative type of research group were used as standard measurement for the purpose of reflecting not only curve length of the 3D analysis measurement but also the difference between front and back thickness to the pattern. Dart locations were set based on front and back torso ease, shoulder area revisions, front sagging length 1.5cm and cross section crevice length analysis. According to the experts' appearance evaluation of the pattern was found to be better than the control pattern which was regarded as the best among 4 patterns created based on existing torso block drafting methods.

This study researches the preferred ease of torso sloper according to body sizes and drop. For this, the eases of main body parts such as chest circumference, waist circumference, hip circumference, biacromion length, and waist back length were analysed; in addition, the drop differences of body and pattern were explored to find out characteristics of silhouette changes. The subjects were 55 women in their early 20s (aged from 20 to 24) and individual torso block made with muslin was corrected 1-3 times by a personal fitting. There were 3 meaningful results. First, the preferred ease were individually various; however, the eases of all torso blocks should be same at the pattern making step. Second, the eases were also significantly different among body size groups and the bigger group preferred less ease at the biacromion length, waist back length, armhole-depth, chest circumference, and waist circumference. Third, the eases of chest circumference and hip circumference were significantly changed among drop groups. To change their body drop, H-shape drop adopted less ease at chest circumference and more ease at hip circumference; however, A-shape drop adopted more ease at chest circumference and less ease at hip circumference.

The goal of this study is to provide basic data on developing circular knit basic pattern for women in their 20's. Production conditions of circular knit product pattern making among domestic women's apparel industry was researched, and collected data on sizes and ease amounts from woven and circular knit pattern were compared and analyzed. According to the result of the survey, product measurements adjusted to the actual body size fit for the brand's image were used, and the common problem among manufacturers and consumers regarding circular knit products turned out to be change in size and form due to stretching. For the basic pattern of circular knit, stretching quality was reflected in the woven basic pattern based on plain stitch(single knit) and then dart was removed and ease amount was reduced. The result of looking into size and ease amount about woven and circular knit torso & sleeve block shows that there is a significant difference among chest circumference, hip circumference, bi-shoulder length, interscye back, interscye front, scye depth, upper arm circumference and wrist circumference, and it was clear that circumference and width on the areas around the wrist tended to fit around the body more when circular knit was used instead of woven fabric.

The purpose of this study is to propose a standard of converting 3D shape of men in twenties to 2D patterns. This can be a basis for scientific and automatic pattern making for high quality custom clothes. Firstly, representative 3D body shape of men was modeled. Then the 3D model was divided into 3 shells, front, side and back. Among them, the front shell was divided into 4 blocks by bust line and princess line. Secondly, curves are generated on each block according to matrix combination by grid method. Then triangles were developed into 2D pieces by reflecting the 3D curve length. The grid was arranged to maintain outer curve length. Next, the area of developed pieces and block were calculated and difference ratio between the block area and the developed pieces' area is calculated. Also, area difference ratio by the number of triangles is calculated. The difference ratio was represented as graphs and optimal section is selected by the shape of graphs. The optimal matrix was set considering connection with other blocks. Curves of torso upper front shell were regenerated by the optimal matrix and developed into pieces. We validated it's suitability by comparing difference ratio between the block area and the developed pieces' area of optimal section. The results showed that there was no significant difference between block area and the pieces' area developed by optimal matrix. The optimal matrix for 2D developing could be characterized as two types according to block's shape characteristics, one is affected by triangle number, the other is affected by number of raws more than columns. Through this study, both the 2D pattern developing from 3D body shape and 3D modeling from 2D pattern is possible, so it's standardization also possible.

A 34-year-old man who previously underwent a craniotomy due to oligodendroglioma was admitted with a diagnosis of recurrent brain tumor. An awake craniotomy was planned. Approximately 15 minutes after completing the scalp nerve block, his upper torso suddenly moved and trembled for 10 seconds, suggesting a generalized clonic seizure. He recovered gradually and fully in 55 minutes without any neurological sequelae. The emergency computed tomography scan revealed a localized fluid collection and small intracerebral hemorrhage nearby in the temporoparietal cortex beneath the skull defect. He underwent surgery under general anesthesia at 8 hours after the seizure and was discharged from the hospital after 10 days. This report documents the first case of generalized seizure that was caused by the accidental intracerebral injection of local anesthetics. Although the patient recovered completely, the clinical implications regarding the scalp infiltration technique in a patient with skull defects are discussed.

국내 패션관련 교육기관은 대부분은 졸업작품 쇼를 행하고 있는데, 학생들이 직접 제작하는 작품 쇼의 경우는 시간적, 경제적 인 여유 부족과 정확한 모델 치수 및 이에 따른 인대와 원형패턴의 부재로 의상 제작 후, 사이즈 수정에 많은 시간을 허비하게 된다. 따라서 본 연구는 대학의 졸업작품 진행 과정의 문제점과 필요한 원형의 종류를 조사하고, 현역 A급 모델의 신체 치수를 계측하여 표준 사이즈를 조사하였다. 이를 토대로 아이템에 따른 원형을 제작, 이를 현역 모델에 착장하여 졸업 쇼를 위한 기본 패턴을 제시하고자 하였다. 졸업작품 쇼는 학교에 따라 진행하는 과정과 기간에 차이를 보이지만 대부분 모델 가봉 후 수선 정도가 많고 경우에 따라서는 의상을 새로이 제작하여야하는 경우도 발생하여 모델 사이즈의 기본원형에 대한 필요성이 많이 나타났다. 모델의 신체 계측결과 모델은 일반인에 비해 슬림하고 가는 체형이며 키가 크고 다리가 길다. 여자의 경우 어깨너비가 일반인에 비해 넓지만 가슴둘레와 허리둘레는 더 가늘게 나타났으며 어깨를 편 바른 자세여서 뒷품과 앞품의 차이가 적었다. 이는 남자 모델의 경우도 같게 나타났고 전체적으로 다리길이와 소매길이의 비율이 크게 나타났다. 여자의 경우 토르소와 스커트, 바지패턴을, 남자의 경우 재킷과 바지 패턴을 머슬린으로 제작하여 현재 활동 중인 A급 남녀 모델 각각 2명씩에게 착장하였다. 제작원형들은 그 맞음새가 모두 적절하였고 남녀 모두 상의 경우는 편차가 적은 어깨너비는 고정하고 품과 둘레항목에서 편차를 주어 패턴을 수정하는 것이 바람직하다. 하의의 경우 여자 모델은 엉덩이 부분에 여유가 없는 바지원형을 설계 제시하고, 이는 타이트 핏 팬츠나 스트레치 소재에 사용에 적절하고 여유 있는 바지의 경우는 엉덩이둘레 폭과 밑위너비 폭에 변화를 주는 것이 바람직하다. 남자모델의 경우 하의는 비교적 잘 맞아 수정이 필요한 부분이 없었으며 전체적인 둘레 편차 역시 3cm 내외로 작아 수정의 폭은 작다. 다만 키에 따른 다리길이 편차가 심해 모델에 따라 길이조정 이 필요하지만 전체적인 맞음새에 영향을 주지 않았다. 이와 같이 본 연구에서 제안한 모델 치수는 현재 우리나라에서 활동하고 있는 A급 모델을 기준으로 제안되었으므로 평균적인 모델 치수와 근접하다고 할 수 있다. 또한 연구패턴 역시 현재 모델의 신체에 적절하게 잘 맞았으며 모델 개인에 따른 신체 치수의 편차에 따라 차이를 보이겠지만 본 연구에서 제시된 패턴의 품 조절만으로도 충분히 잘 맞는 패턴으로 사료된다.
