This study investigated the usage and product conditions of clothing companies and online dummy companies for the development of fitting dummy for South Korean women's wear in their 50s and 60s. These women-targeted apparel companies mainly used nude-sized torso type and torso crotch type made of FRP material. The frequency of use of the dummies was high, while the user satisfaction was moderate. Users expressed dissatisfaction with the inaccurate reflection of the body shape according to the KS sizing system and the measurements such as the front and back intercye, upper arms, abdomen, crotch, and waist back length. Upon survey, 73.7% of the respondents answered that development of the dummy and the appropriate age for it is 50 to 54, and they preferred the torso crotch form. In the production of online dummy companies, the torso crotch type and torso type were most widely produced, and polyurethane, FRP, and recycled paper materials were used. The size of dummy was expressed in numerical type, and 6, 7, 8, 9, 10, 12, 14, 16, 18 and 44, 55, 66, 77, 88 were being produced. Even models of the same size had significant deviation, especially in the waist circumference. Also, there was no dummy reflecting 25%~75% center interval to the KS garment sizing standards of women in their 50s and 60s. Therefore, it is desperately necessary to develop a fitting dummy for KS clothing sizing system that reflect their body sizes and shapes.

This study aimed to provide the Korean apparel companies trying to localize their business in the Chinese markets with some data about Chinese young women's body types useful to the development of the apparel designs fitting the Chinese consumers. To this end, the adult women aged between 19 and 25 living in Beijing, Shanghai and Korea were sampled, and thereby, their body sizes and types were measured. All in all, the results of this study confirmed that Korean and Chinese women in the early 20s had similar vertical body sizes but different horizontal body sizes. In addition, the body types were different between Beijing and Shanghai women groups.

This research was motivated to provide the Korean apparel companies doing business in China with some basic data useful to the development of their apparel commodities. As a result of selecting the standard or 'A' somatotype based on the body measurement data of the Chinese women in their early 20's and then, analyzing the correlated distribution and the most frequent intervals, it was found that 'height 160,' 'bust circumference 84' and 'waist circumference 66' were most prevalent. It was found that their average body measurements almost coincided with the standard '160A-84/66.' As discussed above, the researcher selected 13 women corresponding to '160A-84/66' in reference to 2008 body measurement data, and chose 6 women among them secondarily. Then, the researcher comparatively analyzed the direct measurement data and the 3D measurement ones, while analyzing the vertical/horizontal sagittal and Median plane section drawings, it was found that Subject 4 showed the most common somatotype data, while her upper body bent backwards reflected the population most properly.

The protection of frontal seat passengers in both driver and front seated occupant has been more focused from the auto industries as well as regulatory bodies more than 40 years. Recently, their interests have been extended to rear seat occupants especially children and female occupants. However, the current available safety devices for the rear seat occupants are seat belt only. According to the previous researchers, the injury level of the rear seat passengers tend to be higher than the injury level of the frontal seat passengers. In this study, the optimal location of seat belts anchorages to enhance rear passengers crashworthiness are studied. FEM models are designed in accordance with regulation of KMVSS102, UN R44, UN R16, and UN R14. and three point belts are fitted on the HybridIII 5th percentile dummy and HybridIII 50th percentile dummy. The combined injury value used HIC15, Nij, Chest deflection, Femur force are used to evaluate rear seat belt anchorage optimal locations.

효과적인 가상음장 재현을 위한 머리전달함수(Head Related Transfer Function: HRTF) 측정 시도는 1994년에 이루어진 MIT의 Bill Gardner에 의한 KEMAR 머리전달 함수 측정 이후 이미 여러 차례에 걸쳐 이루어졌다. 그러나 대부분의 시도는 음원이 머리중심점에서 1 m 이 후에 위치한 원거리에 국한되었고 음원이 1 m나 그 이내에 위치한 근거리에서의 측정은 스피커에서 반사된 음파가 dummy head 나 피험자의 귀에 다시 들어가는 것을 막기 어려워 시도된바가 적으며 data 도 공개되지 않은 것이 현 실정이다. 음원이 머리중심점에서 1 m 보다 가까운 거리에 있는 경우 머리전달함수의 특성은 고도와 방위뿐만 아니라 거리에도 영향을 받는 것으로 알려져 있으며, 이를 알아보기 위해 무향실에 B&K HATS (Head and Torso Simulator)를 설치하고 단극음원에 가까우며 반사가 적은 스피커를 따로 제작하여 근거리 머리 전달함수를 측정하였고 이를 분석하였다.

지금까지의 입체음향 재생 연구에서는 Dummy head 나 Head and Torso Simulator(HATS)를 사용한 측정 HRTF(Head-Related Transfer Function)를 사용하여 입체음향 재생 시스템을 설계해왔다. 하지만 이러한 시스템은 구현의 단순함에도 불구하고 계산량 증가로 인한 실시간 구현의 어려움과, 신호처리로 인한 음색의 변화 및 음질의 저하, 정면 정위의 어려움 등 많은 문제점을 내포하고 있었다. 본 연구팀이 제안하는 Relative HRTF는 인체의 가하학적 모델링을 통한 구조적 접근 방법으로 이러한 단점을 극복할 수 있는 새로운 HRTF 모델링 기법이다. 이는 신호처리 과정의 단순화를 통하여 실시간 구현과 음색의 변화를 극소화시키고 스피커 구동 방식에서도 적절히 사용될 수 있다. 또한 본 연구를 위하여 기존의 HRTF 측정 방법의 문제점을 개선한 HATS를 이용한 Blocked Ear Canal HRTF 측정 방법에 대해서도 소개한다.

Setting the ease amount takes the important part to the fit that consumers satisfies. Therefore, it is required to create a pattern for off-the-rack jackets that considers the proper amount of ease. However, few studies have been done previously regarding the ease amount of jacket pattern for the women in their 20s whose demand for jacket is high and who are sensitive to the fit. Therefore, this study selected top five brands in terms of sales and preference among the national female apparel brands. It obtained a tailored jacket pattern for basic size (55 size) and made the jacket. Then, an expert panel group put the pattern on Hani body, a torso dummy for education made by the anthropometric data of Size Korea for females in their 20s and conducted an evaluation on the ease amount and analyzed the results. As a result, the ease amount of the Pattern A was evaluated as proper and that of the Pattern B was found to be lease proper. From the fact, we can see that each of the top 5 off-the-rack brands has different ease amount, though they are of the same basic size (55 size).

This study measured and analyzed clothing pressure at each measurement part of commercial body shapers to provide basic information for product design and clothing pressure standard and level. This study used five body shaper. Clothing pressure measurements were taken at 18points: Anterior area 8points, lateral area 5points, posterior area 5points. The findings of this study were as follows. As a result of measuring the clothing pressure, the body shaper 1 showed the highest pressure, and body shaper 5 showed the lowest pressure at almost of the measurement points of the three body types. In some cases, body shapers 2, 3, and 4 showed different orders of pressure depending on the measurement point. The highest measured values in most body shapers were the P1 shoulder area and the P2 bust area. The lowest measurement area differed by body type, but mainly P3 underbust area, P4 thorax area and P9 axillary area, P11 waist lateral area, P13 hip lateral area. These body shapers showed different results depending on the the manufacturers and body type of middle-aged women, and because there was no standard for the pressure value. Therefore, it is necessary to design a body shaper sizing system after accurately setting the clothing pressure value for each body part of the consumer.
