  • Metal-supported solid oxide fuel cells (SOFCs) have been developed to commercialize SOFCs. This new type of SOFC has high mechanical strength, but its mass transfer rate may be low due to the presence of a contact layer. In this study, the mass transfer characteristics of an anode-supported SOFC and a metal-supported SOFC are studied by performing numerical simulation. Governing equations, electrochemical reactions, and ceramic physical-property models are determined simultaneously; molecular diffusion and Knudsen diffusion are considered in mass transport analysis of porous media. The experimental results are compared with simulation data to validate the results of numerical simulation. The average current density of the metal-supported SOFC is 23% lower than that of the anode-supported SOFC. However, because of the presence of the contact layer, the metal-supported SOFC has a more uniform distribution than the anode-supported SOFC.

  • This study was conducted to establish the effects of subjective body-forming perception on weight-controlling behavior and weight loss, and to suggest the need for proper information and education. Using the data from the National Health and Nutrition Examination Survey conducted in the 6th period (2013-2015), 6,238 women aged 19 and over who have a body mass index of $18.5-25kg/m^2$ were analyzed. As a result, the higher the level of education and income level, the higher they were perceived to be obese, the more they chose to lose exercise and diet in order to lose weight across the board. The weight loss effort rate was higher in the obese body type recognition group, but the body weight type was the highest in the one year body weight change group (p < .001). As a result, subjective perception of body shape affected not only weight control behavior but also weight change (p < .001). Accordingly, it is necessary to have a systematic education on healthy weight-controlling behaviors, proper body image, and healthy body type recognition.

  • 본 연구는 체형의 특성이 현저히 나타나는 40~50대의 Plus-size 여성을 대상으로 체형의 특징이 고려된 치수체계에 대해 맞음새가 우수한 재킷을 개발하고, 이 원형을 토대로 하여 체형의 단점을 보완할 시각적 효과를 연구하기 위해 Plus-size에 해당하는 여성을 선정하여 수트(suit)를 제작한 후 착의 평가하여 Plus-size에 적합한 수트를 제안하는데 목적을 두고 있다. 결과를 요약하면 다음과 같다. 1. Plus-size 여성의 착용실태를 파악하기 위해 실시한 착용실태 조사는 판매자의 측면의 심층면접과 소비자 측면의 착장조사로 구분하여 조사하고 분석하였다. 착용실태조사 결과, Plus-size 여성은 의복구매시 맞음새와 편안함을 중시하고 상완부와 어깨의 두께, 가슴둘레와 복부의 비만등의 체형단점을 갖게 되므로 판매자측에서는 의복제도 시에 등품, 앞품, 상완부, 복부의 여유분을 고려하고 있었다. 시각적 효과로는 세미피트 스타일의 프린세스 라인과 허리선+20, 30cm의 재킷길이, 그리고 테일러드 칼라, 스테인 칼라, 라운드 네크라인이 판매자과 소비자의 양측면에서 선호되고 있었다. 2. Plus-size 여성의 체형에 맞음새가 우수한 재킷원형을 개발하기 위해 Plus-size 여성복의 재킷 원형 중 4종의 기존원형을 선정하고, 착의 피험자 3인을 대상으로 3차에 걸친 착의실험을 통해 연구 원형을 개발하고 평가단을 구성해 객관적인 평가 33문항에 대한 외관 관능검사를 실시하였다. 1) 가슴둘레 여유분을 8~9cm, 허리둘레 여유분을 6~7cm, 엉덩이둘레 여유분을 6~8cm로 적용하여 맞음새를 향상시켜 날씬해 보이는 효과를 높였다. 2) 진동깊이 계산식은 (B/10+10.5)+2cm 적용하고, 진동두께 계산식은 (B/8-1.5)+2cm를 적용함으로써 진동깊이와 진동두께의 편차가 작아짐으로 인해 소매부위와 진동부위의 맞음새를 향상시켰다. 3) 가슴둘레의 증가에 따라 등길이에 앞길이 치수를 증가시키는 계산식을 설정하여 앞가슴둘레의 맞음새를 향상시켰다. 4) Plus-size여성의 경우 허리부분의 신체적합성을 높이기 위하여 사이드 판넬(side panel)의 재킷원형으로 하였다. 앞 허리와 배 부분의 지방 침착이 크므로 앞 허리둘레 다아트 폭과 앞판 사이드 판넬(side panel) 솔기 다아트 폭을 작게 설정하고, 뒤판 사이드 판넬 솔기 폭을 크게 설정하였다. 5) 어깨끝점 사이길이는 다른 부위의 체지방 침착과 같이 비례적으로 증가하지 않으므로 표준체형에 비해 좁게 설정하였다.

  • With rapid expansion in e-retailing of apparel business, the virtual fitting model is used for comparing fit of the selected garments. The researchers experimented women's perceived body size for developing virtual fitting model. 50 women who were 20's in age were participated in the experiment They were graduate students with clothing & textile major. The results of this study showed that the subjects perceived themselves with fuller figure at waist or hips and with shorter figure at waist height than their actual body site. Many subjects believed that their body sizes were close to the average site. Especially, subjects whose abdomen girth of hip girth was much larger than average thought that they have relatively flat abdomen. It was concluded that not only the user's body measurements but also user's perception on their figure type are needed to be considered in the process of developing virtual fitting model for e-retailing of apparel. It was expected that the virtual fitting model of extraordinary size body would not be accepted by the female consumers even though they are extra large or small size person in reality.

  • The purpose of this research was to investigate nursing students' attitude toward body weight control, food behaviors according to their recognition, satisfaction on body image and Body Mass Index(BMI). The subjects were 273 nursing students. A survey was conducted using a self administered questionnaire. The data were an analyzed by a SPSS program. The majority of the surveyed participants were normal range for body mass index(BMI). Most of nursing students preferred a thin body image and were not satisfied with their body image. Most also controlled their body weight for appearance by exercising and the other efforts to change the body weight. From the above results, it is considered that nursing students need to establish proper self-recognition and dietary behaviors for their body images and counseling for desirable body weight control methods.

  • This study was carried out to investigate misconception for physique and desire for physique of college women in Taegu(412 subjects) and Fukuoka(423 subjects). The data was collected by questionnaire interview and anthropometric measurement. The results were as follows : The mean age, height, weight, and BMI of Taegu subjects were $19.9{\pm}1.2$ years old, $159.6{\pm}4.9cm,\;51.2{\pm}6.0kg\;and\;20.1{\pm}2.2$, respectively. The mean age, height , weight, and BMI of Fukuoka subjects were $18.3{\pm}0.6$ year old, $157.5{\pm}5.0cm,\;53.3{\pm}6.9kg\;and\;21.5{\pm}2.5$, respectively. The average ideal height desired by subjects in Taegu was higher than their real mean height by 5.1cm ; while the average ideal weight desired by subjects was lower than real mean weight by 2.6kg. The average ideal height desired by subjects in Fukuoka was higher than their real mean height by 3.2cm ; while the average ideal weight desired by subjects was lower than real mean weight by 5.4kg. The percentage of Taegu subjects who desired to be slender, be fatty and maintain weight were 70.1%, 7.3%, and 22.6% respectively. The percentage of Fukuoka subjects who desired to be slender, be fatty and maintain weight were 85.3%,2.6% and 12.1% respectively. The rate of misconception for the actual physique was 56.5% in Taegu subjects, and 57.2% In fukuoka subjects. The over estimation rate was higher in subjects desired for slenderness than in others. The adolescent females having a fatty body image in self-consciousness indicated that they felt high social physique anxiousness. Finally, the rate of misconception and the degree of social physique anxiousness were higher in those who had a desire for slenderness.
