Echo sounder and Doppler sonar are to theultra-sonic transducers for measuring the depth and the ship's speed respectively. To measure the depth and speed with a single transducer, it is required to control the ultra-sonic beam to optional direction. In the past, the direction of the transducer itself is varied, but such a method provoked much problems in the mechanical design of the equipment. This paper deals with the method to control beam direciton by the phase control of the plural arrangement of transducers, and the results are studied by a computer simulation. The remarkable results of the study is condensed as follows; 1. The greater the interval of arrangement between transducers, the sharper the radiation pattern is, but in this case, the level of undesired sidelobe is also increased. 2. The control of radiation pattern up to 60 degree can be achieved by an adequate arrangement of more than 10 transducers. 3. It is shown that a simultaneous measurement of both depth and speed can be achieved by alternating directivity of the pulse by the method proposed in this paper.

This paper is written to analyze systematically the varieties of informations about cooking stream procedure on the basis of the basic theory of installation and arrangement such as SLP(Systemic Layout Planning) and to deduce the plan for the device, installation and arrangement suitable to cooking stream procedure. Through the substantial improvement in the modeling of hotel L, the optimization of the capacity of installation and arrangement, and the reduction of food resource stream and its movement and through the analysis of cooking stream procedure by disposing and dividing the main kitchen into three individual ones, the improvement of productivity in comprehensive cookery such as the specialization and equalization of cooking procedure and improvement effect of the price-reduction. Moreover, as for the problem of arrangement of installation, it was displayed that the effect went up to twice through the flexible production-related systems such as the improvement of arrangement, reduction of cooking preparation time, the standardization of cookery.

This study aims to provide inspiration and methods for menswear design by analyzing elements for men's fashion using flower images. The results are as follows: Men's fashion types with flower images were categorized as classic tailored, casual tailored, casual wear, sports-outdoor. The order of frquency was casual tailored, casual, classic tailored, and sports outdoor. For the classic tailored type, the flower images are related with an X-line silhouette, and the arrangement methods, such as a scattered patterns, one-point patterns, and surface techniques, such as printing and embroidery were used, and similar color or monochromatic schemes appeared sequentially. For the casual tailored type, the flower images are related to an H-line silhouette, arrangement methods such as a scattered pattern, panel pattern, and surface techniques, such as print, embroidery, and jacquard were used, similar color and accent color schemes appeared sequentially. For the casual type, the flower images are related to H-line and Y-line silhouettes, and arrangement methods, such as a scattered pattern, all-round continuous pattern, and panel pattern, and surface techniques, such as print, jacquard, embroidery, and patchwork were used, similar color and contrast color schemes appeared sequentially. For the sports outdoor type, the flower image were related to A-line and H-line silhouettes, arrangement methods, such as a scattered pattern and all-round continuous pattern, and surface techniques, such as print and jacquard were used, monochromatic scheme and contrast color schemes appeared sequentially. Therefore, the flower images in men's fashion were applied to various design elements, and displayed an interesting result, different from conventional design approach.

In this study, we measured the PD pattern with multiple voids in PET film. The analysis of PD pattern was employed the statistical factor such like CCF(cross correlation factor), asymmetry, kurtosis and etc. The difference of PD patterns caused by arrangement of voids, even if the same size and numbers of void in PET film. Such result of experiment will be used to know the PD source in the real equipment about arrangement and numbers of the defect in insulator.

The correlation between shape of electrical trees and partial discharge(PD) pulses in low density polyethylene(LDPE) were discussed. We observed growth feature of electrical tree by using optical microscope. On the basis of experimental results of measurements of trees occurring in the needle-plane arrangement with needle shape void and without needle shape void , statistical quantities are derived, which are relevant to PD pulse amplitude and phase. The PD quantities detected by partial discharge detector. we were analyzed q-n distribution pattern and $\psi$ -q-n distribution pattern. In this experiment, electrical trees in the needle-plane arrangement with needle shape void propagated branch type tree and in the needle-plane arrangement without needle shape void propagated bush type tree

A major factor in making current hospital gowns is how to manage patients from the standpoint of hospitals. This shows that hospital gowns have not been considered as an apparel for a specific purpose with a design that considers the psychological composure of patients. This study, along with a meticulous analysis of the pattern design of domestic hospital gown suggests a design philosophy that can be of emotional help to patients. The analysis of hospital gowns in terms of motif is that the corporate identity of the hospital in question, along with the lettering symbolizing the hospital is conspicuous. The motif shown in the pattern also has a brightness contrast and two-way pattern. This study suggests hospital gown patterns as follows. First, on the basis of color dynamics, utilize repetition arrangement, camaieu arrangement and faux camaieu arrangement. Second, make use of warm colors in order to enhance trust between patients and medical staff. Last, use green color as a dominant color for the hospital to be felt of as a convenient space. Utilizing these three factors in the future design of hospital gowns will assist in the development of new hospital gowns that render a psychological composure.

This study examined the kinds, expression, techniques and arrangement of patterns for the traditional women's costume from 1995 to 2002 in North Korea. And the results were compared with South Korean. Conclusions are as follows : In the kinds of patterns the natural plant patterns were much more frequently used in North Korea. These tendency was same to South Korea. And the geometric patterns were more frequently used in South Korea. According to frequency in the expression of patterns, it was the realistic, geometric, stylized shape in North Korea. To the contrary it was the stylized, geometric, realistic shape in South Korea. In terms of decorative techniques, not only the traditional embroidery, gold leaf, multicolored stripes, but also modern collages, painting, beads, applique, flounce, ruffle were used in North Korea. Modern techniques were found comparatively a lot in North Korea, traditional techniques were found comparatively a lot in South Korea. In terms of arrangement of patterns, the modern arrangement was much more frequently used. And localized type of modern arrangement was found comparatively a lot in South and North Korea. Therefore traditional beauty was generally expressed by natural patterns, realistic shape and modern beauty was generally expressed by modern techniques and arrangement of patterns in North Korea.

When we develop 2D pattern from replica of human body with small pieces, it is inevitable to have some replica pieces overlapped or departed. In this study, the optimized method of 2D pattern development from the 3D replica pieces was investigated using dress-form. Among six arrangement methods, anchoring two vertexes of a replica to neighboring vertexes of a next replica induces the optimized 2D pattern by evenly distributing stress across the 3D replica pieces. Anchoring neighboring vertexes resulted in automatic widening k overlapping (W & O) the interspaces among replicas of dress-form, thereby stress was distributed more evenly than any other method. W&O arrangement method was verified to be the best by examining the 3D space distribution images between body surface and twelve experimental garments.

초음파센서는 저렴성, 단순한 구조, 기계적 강인성, 사용상의 적은 제약 등의 이점 때문에 다양한 응용분야에 적용된다. 물체의 인식에 초음파센서를 사용하기에는 낮은 분해능을 초래하는 불량한 방향성과 측정오류를 유발하는 반사성의 어려움을 내재하고 있다. 이런 문제를 개선하기 위해서 다양한 센서의 배열형태에서 많은 수의 센서를 사용하거나, 일정 수의 센서를 사용할 경우에는 센서의 배열을 기계적으로 이동시킨다. 본 논문에서는 물체의 패턴인식에 있어서 가장 기본적인 거리, 물체크기, 물체각도 값을 얻기 위해 간단하게 구성된 전자회로를 부가하여 초음파센서의 송출전압을 여러 단계로 변경시켜 얻어낸 데이터에 뉴로퍼지 기반의 지능적 계산 알고리즘을 적용하여 개선된 결과를 얻는다.
