  • 최근 강구조물과 해양구조물에 있어서 박판 부재인 고장력강이 널리 사용되면서 좌굴이 발생할 가능성이 커지고 있다. 특히 선박구조는 상자형 박판 구조물로서 용접이나 절단등의 열 가공에 의하여 필연적으로 판부재에 초기처짐이 발생하게 된다. 이러한 초기처짐은 박판부재가 좌굴을 동반한 복잡한 비선형 거동을 나타낼 때 악영향을 미치는 요소이다. 결과적으로 선체구조물이나 해양구조물에 안정성과 정확성을 부여하기 위해서는 발생 가능한 초기처짐을 이상화하여 2차좌굴 거동을 고려한 붕괴 매커니즘을 초기구조설계에 반영하여야 한다. 본 연구에서는 종방향 압축하중이 작용하고 네변 단순지지조건인 판에 실제 계측된 여러 가지 초기처짐형상을 적용한 유한요소 해석을 하였다. 해석방법으로서는 범용 유한요소프로그램인 ANSYS의 탄소성대변형 유한요소법을 적용하였고 해석제어는 Newton-Raphson method와 Arc-length method를 병용하였다.

  • The purpose of this study is to examine the vest patterns with better fitness, function and beauty best suited to the bodies because the previous studies on the vest pattern are not enough to be usable for its making and wearing including the emperiment and practice as well as its direct design and cutting although its wearing range has been widely popular. This study was carried out by making the experimental vest and performing its wearing experiment. The result of this study is summarized as follows. 1. The sensory evaluation on apperance showed that the wholoe average of pattern 4 was the highest for all S, M, L bodies. In addition, it was shown by the bodies that the most suitable related patterns included pattern 4-M body, pattern 2-S body and pattern 4-L body. However, the L body indicated the lowest score in all patterns. Then, this fact means that the diversified studies must be carried out on the vest patterns for the bodies. 2. The results on the function of vertical motions indicated that when the motion angle increased the lifting volume of the vertical motion also increased proportionally, and that the motion at $135^{\circ}$ among these verical motions showed the highest score. Therefore, it is required to consider this fact when determining the vest length in the process of making the vest pattern. 3. The results on the twisted degree of a posture showed that as to the experimental results on these vertical motions the twisted degree increased with the increase of angle. This fact seems to be also important in deforming the vest length when making the vest.

  • Recently, Basic patterns with excellent body fitness and automation availability are required to be developed in order to automate the patterns of women's clothes. In this study, this reference points, reference lines and segments were fixed onto 3D scan data for the lower body the women in their twenties, they were directly spread out to be 2D flat pattern to facilitate development into the design of slacks adhered closely to the human body such as special and highly-functional clothes, and then slacks 2D pattern was developed for the purpose of seeking scientific approach to the development into basic form slacks and 3d emotional pattern. For conversion of 3D pattern into 2D flat pattern, reference points and segments were created by using Rapid Form of 3D shape analysis software, and triangle mesh of the body surface of the created shape was developed with Auto CAD 2005. The correspondence between slacks and human body was examined by the fixation of major reference lines. Specially, the wearing characteristics of slacks were considered by the fixation of side lines in consideration of posture. As a result of using the way of development to constantly maintain the length while 3D triangle mesh is converted into 2D flat mesh, the shape was shown to be excellently reproduced, and the area of flat pattern was increased compared to the shape of parting plane. Also, the sunk-in curve like the brief line of front crotch length needed a cutting line when it was closely adhered, when mesh was overlapped, and the pattern area was smaller compared to the actual shape.

  • This research was carried out by analyzing a form and composition in baseball cap targeting 97 marketing products, and we have typified it by frequency analysis. We have carried out comparing and wearing test between comparative pattern and the most preferred three products of sports brand, fashion brand A, and fashion brand B (flex fit). And also, in order to provide basic indices for developing new pattern, we have carried out analysis of variance. 1. As a result of analyzing a form in baseball cap, the most general pattern type for crown is central cutting with six pieces. In a cap, a basic type with no decoration was the most general. In the size adjustment and decoration, belt type and embroidery type (front or side embroidery of the crown) was the most common, respectively. 2. As a result of comparing and analyzing six-piece typed crown pattern, the comparative pattern was the same and symmetric in size and form of three patterns in front, side, and back. However, the patterns of marketing products of three brands were different in size and form of three patterns in front, side, and back. The patterns of sports brand were the largest in crown height and width, thus it was good at providing activity and motion. The patterns of fashion brand A were the shortest in the crown length and well-curved in front pattern, so it was well-matched with head shape. The patterns of fashion brand B were well-described back side of head since its convex and long patterns in the back head. 3. As a result of wearing test by five-point Likert scale among brand, pattern of fashion brand B outperformed the others since it was well-matched with head shape. In the cap, pattern of fashion brand A is the most preferred which was 7.5 cm of length and 18cm of width.

  • Many plant growth-promoting rhizobacteria (PGPRs) have been known for beneficial effects on plants including biological control of soilborne pathogens, induced systemic resistance to plant pathogens, phytohormone production, and improvement of nutrient and water uptake of plants. We developed a simple and rapid method for screening potential PGPR, especially phytohormone producing rhizobacteria, or for analyzing their functions in plant growth using cucumber seedling cuttings. Surface-sterilized cucumber seeds were grown in a plastic pot containing steamed vermiculite. After 7 days of cultivation, the upper part 2 cm in length of cucumber seedling, was cut and used as cucumber cuttings. The base of cutting stem was then dipped in a microcentrifuge tube containing 1.5ml of a bacterial suspension and incubated at $25^{\circ}C$ with a fluorescent light for 10 days. Number and length of developed adventitious roots from cucumber cuttings were examined. The seedling cuttings showed various responses to the isolates tested. Some isolates resulted in withering at the day of examination or in reduced number of roots developed. Several isolates stimulated initial development of adventitious roots showing more adventitious root hair number than that of untreated cuttings, while some isolate had more adventitious root hair number and longer adventitious roots than that of untreated control. Similar results were obtained from the trial with rose cuttings. Our results suggest that this bioassay method may provide a useful way for differentiating PGPR's functions involved in the development of root system.
