본 연구는 체형의 특성이 현저히 나타나는 40~50대의 Plus-size 여성을 대상으로 체형의 특징이 고려된 치수체계에 대해 맞음새가 우수한 재킷을 개발하고, 이 원형을 토대로 하여 체형의 단점을 보완할 시각적 효과를 연구하기 위해 Plus-size에 해당하는 여성을 선정하여 수트(suit)를 제작한 후 착의 평가하여 Plus-size에 적합한 수트를 제안하는데 목적을 두고 있다. 결과를 요약하면 다음과 같다. 1. Plus-size 여성의 착용실태를 파악하기 위해 실시한 착용실태 조사는 판매자의 측면의 심층면접과 소비자 측면의 착장조사로 구분하여 조사하고 분석하였다. 착용실태조사 결과, Plus-size 여성은 의복구매시 맞음새와 편안함을 중시하고 상완부와 어깨의 두께, 가슴둘레와 복부의 비만등의 체형단점을 갖게 되므로 판매자측에서는 의복제도 시에 등품, 앞품, 상완부, 복부의 여유분을 고려하고 있었다. 시각적 효과로는 세미피트 스타일의 프린세스 라인과 허리선+20, 30cm의 재킷길이, 그리고 테일러드 칼라, 스테인 칼라, 라운드 네크라인이 판매자과 소비자의 양측면에서 선호되고 있었다. 2. Plus-size 여성의 체형에 맞음새가 우수한 재킷원형을 개발하기 위해 Plus-size 여성복의 재킷 원형 중 4종의 기존원형을 선정하고, 착의 피험자 3인을 대상으로 3차에 걸친 착의실험을 통해 연구 원형을 개발하고 평가단을 구성해 객관적인 평가 33문항에 대한 외관 관능검사를 실시하였다. 1) 가슴둘레 여유분을 8~9cm, 허리둘레 여유분을 6~7cm, 엉덩이둘레 여유분을 6~8cm로 적용하여 맞음새를 향상시켜 날씬해 보이는 효과를 높였다. 2) 진동깊이 계산식은 (B/10+10.5)+2cm 적용하고, 진동두께 계산식은 (B/8-1.5)+2cm를 적용함으로써 진동깊이와 진동두께의 편차가 작아짐으로 인해 소매부위와 진동부위의 맞음새를 향상시켰다. 3) 가슴둘레의 증가에 따라 등길이에 앞길이 치수를 증가시키는 계산식을 설정하여 앞가슴둘레의 맞음새를 향상시켰다. 4) Plus-size여성의 경우 허리부분의 신체적합성을 높이기 위하여 사이드 판넬(side panel)의 재킷원형으로 하였다. 앞 허리와 배 부분의 지방 침착이 크므로 앞 허리둘레 다아트 폭과 앞판 사이드 판넬(side panel) 솔기 다아트 폭을 작게 설정하고, 뒤판 사이드 판넬 솔기 폭을 크게 설정하였다. 5) 어깨끝점 사이길이는 다른 부위의 체지방 침착과 같이 비례적으로 증가하지 않으므로 표준체형에 비해 좁게 설정하였다.

Education of clothing and textiles in the university is various according to the purposes. Among that clothing construction and practice is what is needed the most in understanding the process of apparel producing, and is the basic subject of areas from apparel designs to quality management. Producing apparel starts from planning the bodice pattern according to the human body shape. Basic bodice pattern should be highly practical so that production of all items of apparel patterns can be possible. Also, a basic bodice pattern needs to be planned in the way that even beginners can use it by classifying sizes according to each body measurements. Thus in this study. bodice patterns will be produced in way of draping method subjecting university students in early 20s. standardized and classified sizes will be calculated from it and bodice pattern made by studied flat pattern method will be examined and compared so that finally suitability will be compared. As a result of examining and comparing bodice patterns made by draping method and studied flat pattern method on the model of the human body produced by plaster method, sizes were classified into 5 levels. As a result of evaluation of creation. satisfying consequence from various body shape was acquired and it is expected of the beginners who are stating from clothing construction and practice to be educated by using the result of this study.

The three-dimensional structure of detonation wave propagating in a circular tube was investigated using a parallel computational code developed previously. A series of parametric study for a circular tube of a fixed diameter gave the formation mechanism of the detonation cell structures depending on pre-exponential factor, k. The unsteady results in three-dimension showed the mechanisms of two, three and four cell mode of detonation wave front structures. The detonation cell number was increased but cell width and length were decreased with increased pre-exponential factor k. In the all multi-cell mode, the detonation wave structure and smoked-foil records on the wall are made by the moving of transverse waves. The detonation wave front structures have the regular polygon and windmill shapes periodically.

In this study, we analyzed the results of virtual clothing simulation according to the difference in the lateral neck point as well as the front and back shoulder inclination angles of the bodice foundation. Lim's (2016) (S) and Lee's (1999) method (L) were selected as the different setting for the lateral neck point. S1, S2, L1 and L2 were developed by changing the shoulder inclination angles. The SND and LND were developed by removing the darts in the S and L, respectively; in addition, the SND1, SND2, LND1, and LND2 were developed with different shoulder inclination angles. The results of S and L were similar with only slight differences observed in the armhole shape. However, the results of SND and LND were very different. The patterns of the S series were similar to each other, but the patterns of the L series were different. In addition, the patterns of the SND and LND series could not find a similar trend.

국내에 유통되는 제초날은 대부분 금속으로 제작되며, 금속 날의 대부분 탄소공구강(SK-3~5)으로 제작되고, 날 수 및 날 형태에 따라 2도 날, 3도 날, 4도 날, 8도 날, 톱날로 구분된다. 대부분 평지 제초작업에 사용되고, 고랑 제초 작업에 알맞은 제초날의 없어 고랑 제초 작업의 효율이 떨어진다. 본 연구는 굴곡이 있는 밭의 고랑 제초 작업에 효율적인 원형 제초날을 설계 하고자 한다. 밭작물의 제초작업은 굴곡이 있는 이랑과 고랑 사이의 잡초를 제거해야 하기 때문에 평지의 잡초를 제거하는 제초날로는 제초작업이 거의 불가능하다. 따라서 고랑 형상에 맞는 원형 제초날을 설계 하였으며, 회전 균형 및 무게의 균일성 설계가 쉬운 뼈대형 원형 제초날을 설계한 후 데이터를 이용하여 원형 제초날을 설계하였다. 또한 고랑의 잡초 뿌리부분을 제거하기 위해 원형 제초날에 돌출부를 추가하는 방법으로 설계하였다. 제초날은 밭작물 고랑폭을 기준으로 하여 높이는 85mm 직경은 300mm로 설계하였으며, 제초날 설계시 원형 제초날은 뼈대형 원형 제초날과 같이 고랑폭을 기준으로 하여 높이 및 직경을 뼈대형 원형 제초날과 동일한 치수로 설계하였다. 원형 제초날 설계에서 돌출부를 볼트 결착방식으로 설계하였으며, 회전중 돌출부의 파손 혹은 이탈을 방지하기 위하여 직경 5mm이상의 볼트 결착이 필요하였다. 볼트 결착방식은 제초날 조립후 제초날 회전시 고랑의 잡초를 효과적으로 제거하기 위한 작업공간 확보가 어려울 것으로 판단되었다. 따라서 제초날 원형부에 돌출부를 절단 절곡하는 방식으로 돌출부를 재설계하였으며, 돌출부 길이는 안쪽 부분 15mm, 바깥 부분 20mm로 설계하고, 돌출부 회전반경은 안쪽 날 20mm, 바깥 날 10mm로 설계하였다. 일반적인 제초날 과 달리 원형 제초날을 개발하기 위해서 회전균형과 안전이 제초날 설계에 중요한 요인이 된다. 뼈대형 제초날을 통하여 제초날의 균형 데이터를 분석하였고 이를 바탕으로 원형 제초날을 설계하였다. 또한 발란싱 머신을 이용한 회전시험에서 unbalance 정도가 3,600rpm에서 4.51/47.1deg로 나타나 제초기에 적용 가능할 것으로 판단되었다.

본 논문에서는 터널 구조물에서 발생하는 균열의 인식과 이에 대한 정보를 획득하기 위한 방법에 대한 연구를 수행하였다. 터널 구조물에서 발생하는 균열의 경우, 건설 분야의 특수성 때문에 기존의 경계점 인식(edge detection) 알고리즘을 적용하는 경우 정밀도 저하의 문제가 발생한다. 이러한 문제점을 해결하고 더불어 정밀도를 향상시킬 수 있는 방법으로 영상에서 균열을 인식하는 균열 인식 단계와 인식된 균열의 길이, 두께 등을 측정하는 균열 정보 획득 단계로 구분하였다. 균열 인식 단계에서는 균열의 시작점과 끝점을 기준으로 휴리스틱(Heuristic) 알고리즘을 사용하여 픽셀 값의 분포에 따라 균열의 중심선을 계산하여 균열을 인식한다. 균열 정보 획득 단계에서는 균열 인식 단계에서 얻은 정보를 통해 균열의 길이, 진행 방향 정보, 그리고 균열의 두께를 계산한다. 균열의 길이 및 진행 방향 정보는 균열 인식 단계에서 얻어진 정보를 통하여 계산하며, 균열 두께 측정은 각 픽셀의 누적 값을 이용하여 계산하는 원형 검출기(Daugman 알고리즘)를 변형하여 사용하였다.
