An industrial robot noise has various noise sources such as gears, motors, bearings, and controller fans. Among these, gears are the most dominant source for noise. The gear noise, caused by tooth profile, elastic deformation, machining error and wear, is directly correlated with the transmission error of mating gear. Due to the fact that has several axis and many gears, it is difficult to understand the characteristics of the vibration and noise of robots. In this study, some advanced analysis techniques based on digital signal processing such as power spectrum, time spectral map, RPM map, and etc., were applied for locating the dominant frequency components of the robot noises and identifying their sources. In addition, sound quality analysis was performed in order to evaluate the operator's annoyance. The noise and vibration measurements were carried out at several points during the operation of each axis considering the effect of load and posture of the robot. Eased on the results, proper countermeasures to reduce excessive noise level have been suggested considering the characteristics of sources.

We studied on the development of clothing pressure measurement system for wear comfort of foundations(girdle, brassiere, all-in-one). Measurements of clothing pressure were made on subjects wearing girdles, brassieres, all-in-ones of several type(material, size) using by CPMS(clothing pressure measurement system: Tech-Storm. Co). Wearing experiments have been carried out using nine women in the twenties and six women in the forties. The results obtained are as follows: 1. The clothing pressure applied by girdle was higher in the hard type than the soft type by $5-10gf/cm^2$, also recorded a high clothing pressure at points of waist band line and thigh lateral. 2. Clothing pressure of brassiere with wire was high at the point of underbust line and shoulder strap. Pressure for 40s showed higher than 20s by $6-7gf/cm^2$. 3. The pressures of abdominal part applied by both of girdle and all-in-one were much greater than those of girdle or all-in-one. 4. We demonstrated the adaptability and conformity of the CPMS by inquiring into the clothing pressure of various foundations.

The objective of this study is to analyze the coordination images seen in comprehensive fashion items and their features. This will be done from the viewpoint of both the creativity as well as functional characteristics of items and images. For the method of study, I explored the idea of "snood" style, analyzing its features of 42 pictures appearing from the 2006 S/S to 2010 F/W collection. It is important to note that "snood" style has the characteristics of both a muffler and turtleneck. With looping design connected at both ends, it can be placed around the neck or head, creating the image of wearing a hood. After having examined the selected data and pictures, one can largely divide the exclusive high-fashion image categories into three types: feminine, avant-garde, and finally, active & functional sportive image. First, the orthodox image is widely accepted by most as it has forever evolved within the original tradition of the practically functional muffler(scarf). Second, since the metamorphic image tends to lend itself to free ideas, you can wear a snood around the shoulders like a collar. Worn together with the same type of clothing, the snood can be seen as an effective suit. Third, the aim of image emphasis is to highlight certain points, or make some features more noticeable, as a means of possibly attracting more interest and attention. The image of snood arises out of the use of shapes, colors, and other accessory parts. As mentioned earlier, snood stands out as an independent item instead of just being an accessory to clothing. Its primary function as a style coordinator is emphasized in order to create more distinctive fashion images. Through this study, I thereby intend to provide fashion style data on the latest trends, and high-fashion codes of snood coordination.

This study was conducted to find out the purchasing characteristics, the wearing practices and the preferring style of skirts. Also the comparison between recognized body type and actual body type for skirt was analyzed. The questionnaire was developed and administered to 179 women aged 20 to 59 in Busan. The women of 20th liked to buy skirts at the road shops and the internet shops but the 30th, 40th and 50th at the department stores and the discount stores. The main purpose of buying skirts was to coordinate with other clothes. The design of skirt was the most important factor of buying. The women of the 20th wore skirts without special purpose but the 30th, 40th and 50th wore those for social life. The women of the 20th liked to wear skirts with t-shirts and cardigan, the 30th with blouse and cardigan and 40~50th with blouse and jacket. As the age increased, the ratio of women who felt discomfort of skirts increased. Most of these women felt discomforts in the waist and abdomen part of skirt. The style of skirt that made up for the weak points in the body type was preferred. The preferred silhouettes of skirts were semi-tight and A-line. The preferred lengths of skirts were different from ages. Black was preferred color of skirts. There was a significant difference in recognized body type according to age groups. As the age increased, the ratio of women who thought themselves as thick waist type increased. Just only 43% women of total subjects recognized their body type accurately.

플래시 메모리의 성능평가 실험 환경 구성은 플래시 메모리가 장착된 제품들이 동작하는 시스템으로 이뤄진다. 이와 같은 방법은 물리적이고 비용적인 제약이 따르게 된다. 또한 실험에 쓰이는 입력 데이터와 FTL 알고리즘의 성능평가를 위한 결과 데이터인 트레이스의 추출 방법이 까다롭고 힘들다. Oracle의 경우 트레이스 추출이 불가능하고, MySQL, SQLite는 트레이스 추출이 가능하더라도 결과의 정확성이 보장되지 않는 문제점이 있다. 따라서 본 논문에서는 디바이스 드라이버를 통해 물리적 제약을 없애고 트레이스 추출을 쉽고 간편하게 하여 정확한 실험 결과 분석이 용이하도록 FTL 에뮬레이터를 설계하고 구현한 내용에 대해 다룬다. 본 논문에서 제안한 FTL 에뮬레이터인 FlaSim은 플래시 메모리의 데이터 저장 메커니즘과 동일한 동작을 하도록 구현하고 리눅스 커널 모듈을 사용하여 필요한 기능을 추가할 수 있다. FlaSim은 모듈 적재 방식을 사용하기 때문에 FTL 알고리즘 및 플래시 메모리에 대한 실험의 확장성을 향상시킨다. 또한 다양한 응용프로그램에 적용이 쉽고, 플래시 메모리에 대한 실험의 제약이 되는 물리적인 비용을 줄일 수 있다. 게다가 트레이스 추출하는 데 쉽고 효율적인 방법을 제공하여 결과 도출 및 분석 시 시간적, 시스템적 제약을 받지 않아 효율성이 큰 장점이 있다. 추후 많은 FTL 알고리즘 및 플래시 메모리에 대한 실험과 연구에 도움이 될 것으로 예상된다.

This study develops a fitted torso type basic pattern for men by utilizing 3D body scan data. Recent fashion trends are reflected in the development of the pattern. The subjects were 15 men in their 20's, who wear size 95 (M size). Body scan data was obtained through a 3D whole body scanner (WB4, Cyberware, USA), and a body surface development figure for developing male fitted torso type basic pattern was attained through the use of Rapid Form 2006 as well as Auto CAD 2006 programs. The results are as follows: A body surface development figure through body surface segment method showed high exactitude in an error range of 100$\pm$1%. In addition, it occurred in an error range of 100:1:3% because of the hard scanning conditions in the incline of the shoulder and armpit areas. However, the body surface development figure as well as the direct measurement results can be used as basic data for the given patternmaking since the error range falls into 100$\pm$3%. Dart amounts obtained from the average cross section were center back 2.2cm (24.3%), back armpit point 3.8cm (41.8%), front armpit point 3.0cm (33.9%). As shown the jacket pattern, the biggest dart amount was portioned out at the back armpit point. The drafting equations for the development pattern acquired are as follows; Full width=C/2+5cm, back length=height/4-1cm, armhole depth=(C/10+12cm)+3cm, back width=2C/10+2cm, front width=2C/10. The development pattern was a fitted torso basic pattern that was composed of 3 pieces, so it would be very useful in developing shirt or jacket patterns. According to the results of the evaluation of the developed pattern appearance, it obtained higher scores of over 3.5 points in almost items, meaning that the developed pattern is appropriate for a male fitted torso type basic pattern. It suggests a possibility of patternmaking from a body surface development figure in 2-D to prototype.
