이 논문은 선박에서 자세 안정용 양방향 축류펌프에 대한 임펠러 블레이드의 형상최적설계를 설명한 것이다. 양방향 축류펌프용 블레이드는 대칭형 익형을 사용하므로 효율이 기존의 단방향 축류펌프보다 낮다. 이러한 양방향 축류펌프의 단점을 최소화 하고 효율을 증가시키기 위해 최적설계기법을 사용하였다. 양방향 축류펌프의 성능 개선을 위해 상용 CFD 프로그램인 ANSYS CFX v.13 을 이용하여 유동해석을 수행하였다. 직교배열표, 분산분석과 직교다항식을 이용한 대리모델기반 최적설계방법은 최적 설계변수를 결정하고 주효과를 찾는데 사용하였다. 최적설계 결과로부터, 임펠러 블레이드의 유효한 설계변수를 확인하고 이의 최적해와 설계요구조건 만족에 대한 유용성을 설명하였다.

도로터널내 열유동장의 형성은 여러 가지 요인의 영향을 받는다. 즉 차량의 이동에 의한 피스톤 효과, 환기설비의 환기력, 자연풍 영향, 화재시 부력 등에 따라 도로터널내 기류가 형성된다. 차량의 이동에 의한 피스톤 효과는 도로터널내 기류생성의 일차적인 요인이며, 화재시 연기의 초기 거동에 영향을 줄 수 있다. 본 연구에서는 도로터널내 차량의 이동에 의해 생성되는 비정상 기류를 분석하기 위해서 단순한 형태의 터널과 차량에 대한 축소모형실험장치를 제작하고 실험을 수행하였다. 기본형, 전두부 사변형, 후두부 계단형의 3가지 형태로 차량의 형상을 변화시켜가며 차량운행에 따라 형성되는 터널내 압력과 기류속도를 측정하였다. 실험결과 터털내 생성되는 압력과 속도의 크기는 "기본형>후두부 계단형>전두부 사변형"의 순서로 증가하였다. 실험결과는 향후 3차원 수치해석 결과와의 비교, 검토를 통해서 수치해석 기술의 보완 및 신뢰성 확보를 위한 기초자료로 활용될 수 있다.

사회가 발전할수록 공공장소에서 개인 및 시설물의 안전에 대한 중요성이 높아진다 기존의 주차장, 은행, 공장 등 보안이나 범죄 예방이 요구되는 지역은 넘어서 일반 기관, 개인의 주택까지 감시 및 보안에 대한 투자가 증가하는 경향을 보이고 있다. 이 논문은 얼굴인식에 있어서 중요한 얼굴 영역과 머리 영역을 칼라변환을 이용하여 간단하게 분리하는 방법과 얼굴특징 추출을 제안한다. 먼저 입력영상에 대한 CMYK영상 중 K영상을 가지고 머리 영역을 분리한 후에 YIQ영상의 Y영상과 머리 영상과의 칼라변환을 이용하여 얼굴영역을 분리한다 머리영상에 Log 연산을 한 후에 라벨링을 이용하여 얼굴의 특징들을 추출한다. 뚜렷하게 분리된 머리와 얼굴영역은 머리와 얼굴의 형태를 쉽게 분류할 수 있으며, 쉽게 특징점을 찾을 수 있게 한다. 제안한 방법의 알고리즘을 이용하면 중요성이 요구되는 보안 관련 시설에서 사람을 감시하거나 인식하는데 효과적으로 이용될 수 있을 것으로 예상된다.

Background and Objectives : Boundary detection and drawing are essential in 3D reconstruction of neck mass. Manual tracing methods are popular for drawing head and neck tumor. To improve manual tracing, circular boundaries overlapping was tried. Materials and Methods : Twenty patients with neck tumors were recruited for study. Representative frames were examined for shapes of outline. They were all single closed curves. Circular boundaries were added to fill the outlines of the tumors. Inserted circles were merged to form single closed curves(Circular boundary overlapping, CBO). After surface rendering, 3 dimensional images with volumes and area data were made. Same procedures were performed with manual tracing from same cases. 3D images were compared with surgical photographs of tumors for shape similarity by 2 doctors. All data were evaluated with Mann-Whitney test(p<0.05). Results : Shapes of boundaries from CBO were similar with boundaries from manual tracing. Tumor outlines could be filled with multiple circular boundaries., While both boundary tracing gave same results in small tumors, the bigger tumors showed different data. Two raters gave the similar high scores for both manual and CBO methods. Conclusion : Circular boundary overlapping is time saver in 3 dimensional reconstruction of CT images.

The objective of this study is to help golfers to select adequate putters and to provide golfers basic scientific data for improving athletic performance by showing differences of kinematic variables according to the shape of putter head. In this research three right-handed male pro-golfer who are listed at KPGA were studied and three video camera (GR-HD1KR, JVC, Japan) were used and recording speed was 60 frame/sec during the research. In this study kinematic variables were calculated using Kwon3D XP program and analysed on the 4 events and 3 phases. This study showed the following results : (1) The swing of heel-toe putter showed longer time than that of face balanced putter, and there are statistical significant difference of kinematic variables of each objective (2) As of the trajectory of putter head, heel-toe putter showed more approximating curve trajectory than that of in-between, face balanced putter on the X-axis (3) heel-toe putter showed longer distance follow-through than that of other putters by statistically significant difference on the Y-axis (4) Heel-toe putter showed longer distance swing trajectory over the ground than that of other putters by statistically significant difference on the Z-axis.

This article studied women's headdresses that appeared in the paintings of Joseon Dynasty. This examined the shapes of women's headdresses painted in genre paintings, record paintings and nectar ritual paintings from Joseon Dynasty and compared them to literatures and relics in order to analyze their types and characteristics. Headdress can be categorized into three types: (1) square cloth worn on the top of the head; (2) a kind of small cap; (3) Cloth that completely covers the head. The first type of headdress resembles the shape of Garima. In the early period of Joseon Dynasty, it was worn not only by Gisaeng, but also by both upper and lower class women. The second type of headdress includes a cap made by connecting several cloths, round cap, and cone-shaped cap. These two types are worn on top of the head. However, sometimes these were worn between the head and the chignon to fix the chignon. Also, these were used as hair accessories for decorative purposes. In particular, old women wore these headdresses and braided their white hair around them to fix the chignon. This way, the headdress not only kept the head warm, but also hid the old women's scanty hair. Headdress was usually made of black fabric and it was a simple hair accessory that replaced the wig. The third type of headdress was widely worn among lower class women. The cloth completely covered the head so that the hair would not fall when working. It also provided protection from cold and hot weather. According to paintings, there were many ways of wearing the cloth around the head.

이 논문은 콘크리트 콘 파괴에 의해 지배될 때의 인장력의 예측과 Headed bar의 인발 파괴 양상을 보여준다. 1개의 다른 플레이트 형상과 세가지의 서로 다른 용접 방법에 따라 시험이 이루어졌다. 시험의 변수는 Headed plate에 연결된 철근의 직경(16mm, 19mm, 22mm), 형상(원형, 직사각형, 정사각형)과 head plate의 차원(면적, 두께), 철근과 head plate와의 연결을 위한 용접 방법(일반용접, 마찰용접)이다. Headed bar는 ASTM 970-98에 기초한 모양과 두께를 가진 다른 단면적으로 제조되었으며 콘크리트의 부착 길이는 CSA 23.3-94에 의거하여 산정되었다. 정적 인장하중이 적용되었으며 시험 인발 성능은 ACI-349와 CCD 방법과 같은 현재의 설계방법에 의해 산출된 값과 비교하였다. 실험결과와 기존식을 비교하면 Headed bar가 앵커와 달리 넓은 플레이트 면적과 이형철근으로 인해 기준식에 비해 높은 강도와 큰 파괴 반경을 나타내었다.

The Electrostatic Inkjet system has many applications in cost and time effective manufacturing of printed electronics like RFIDs, OLEDs and flexible displays etc. This paper presents pneumatic ink supply system for an electrohydrodynamic deposition (EHD) setup for the precise pressure control to produce a small amount of discharge at the end of the capillary. The meniscus shape depends upon the applied pneumatic pressure to the ink supply system. Furthermore, this paper also compares meniscus shapes at different applied pneumatic pressures. It is concluded that patterning of constant line-width can be achieved better by controlling the meniscus shape using this technique.

Hair styles for human being develope according to the natural environment. Chinese hair styles have been changed from tousled hair to pigtailed hair, later additional style of shaved hair, became pigtailed. Each hair style for people, however, is based on each people's culture and history. Thus, the same changed had not been applied to each culture simultaneously. Hairstyle for Yao(遼) Jin(金) Yuan(元) that is a representation of ancient northern tribe, is summarized as follow; Tung Hu'(東胡)s inferior, Khitai(契丹)'s hair style is tousled hair and Sushen(肅愼),'s inferior, Jurchen(女眞) has partial shave and left 2 strand of pigtail. Hun'(匈奴)s inferior, Mongol(蒙古) has hair in top and shaved head except both sides and rear. One style is circular shape of braided hair at both sides. The other is one strand pigtail at the rear head, which is the original shape for Man'(滿) pigtail later.
