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 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.

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.

Ultrasonic sensor is used widely for many applications because low cost, simple structure, and low restriction. There are many difficulties to recognize an object by use an ultrasonic sensor, because of low resolution, poor direction, and measurement error. To improve the these problem, we use the various kinds of sensor arrangement methods, large amount of sensor, and change the arrangement pattern of sensor. In this paper, to obtain the most basic parameters for pattern recognition such as distance, dimension of the object, an angle of the object, we get the improved results by use the intelligent calculation algorithm based on Neuro-Fuzzy. This method use the multifarious output voltage of ultrasonic sensor by simple electronic circuit.
