Purpose: The Purpose of this study was to examine the degree of obesity stress and analyze factors having an effect on obesity stress among college women. Method: The subjects were 347 female students from a university in J City. Data were collected using a self-report questionnaire for general characteristics, health-related characteristics, and current and preferred somatotype. Obesity stress was measured using 10 items developed by Cho (1996) based on Body Attitudes questionnaire (BAQ) of Ben-Tovim and Walker (1991). The survey was conducted from September 4 to September 7, 2007. Data were analyzed by t-test, ANOVA, Scheffe test, Spearman's rank correlation test, and stepwise multiple regression using SPSS 14.0. Results: The average score of obesity stress was $2.78{\pm}0.90$ out of 5.00. Stepwise multiple regression analysis showed that the major factors that affect obesity stress of female college students were perceived body shape, disagreement between current and preferred somatotype, history of weight control, body mass index (BMI), and perceived health status, and these factors explained 38.4% of obesity stress. Conclusion: Subjective judgment in the perception of or preference for body shape was the most important factor affecting obesity stress in female college students. Therefore, a plan is necessary to mitigate obesity stress and evaluate individually subjects who perceive themselves to be fat or want to be thinner than the current somatotype. And consultation and constant management are needed to help the high risk group (experience of weight control, BMI ${\geq}23kg/m^2$, not good health status).

A bus seat is required to be ergonomically designed in terms of its shape and physical properties to increase seating comfort. The present study is intended to develop a systematic bus seat evaluation protocol based on seating comfort. A total of 48 participants evaluated 12 parts (seat belt, recliner, armrest, headrest, upper-back support, lumbar support, seatback bolster, seatback overall, hip support, thigh support, seatpan bolster, and seatpan overall) of 12 bus seats with 17 subjective comfort measures (e.g., convenience of control, suitability of size, and overall comfort). Lastly, ergonomic features of shape and physical properties of each seat part were identified based on the subject evaluation analysis results. The developed bus seat evaluation protocol can be applied to evaluate various types of seats.

Background: Both objective body shape and perceived body image have been known to influence the mental health. The purpose of this study was to explore the relationship of a combination between actual body mass index (BMI) status and perceived body image with anxiety depressive condition (ADC) in Korean men and women. Methods: This cross-sectional study analyzed data of 26,239 subjects ${\geq}20$ years old from the National Health and Nutrition Examination Survey (2010-2014). This study performed a Rao-Scott chi-square and multivariate logistic regression analyses reflecting survey characteristics and used a variety of independent variables such as socio-demographics and health behavior factors. Results: With all independent variables considered, people with normal weight who perceived themselves as overweight were more likely associated with ADC than a referent group with normal weight who perceived themselves as normal weight, as shown for both men (odds ratio [OR], 1.52; confidence interval [CI], 1.07-2.15) and women (OR, 1.25; CI, 1.06-1.48). Meanwhile, compared to the referent group, men with underweight who perceived themselves as underweight showed a lower association with ADC (OR, 0.63; CI, 0.41-0.97), whereas women with underweight who perceived themselves as underweight showed its higher association (OR, 1.47; CI, 1.10-1.96). Conclusion: A certain group of people categorized as a combination between actual BMI status and perceived body image showed a relatively high likelihood of having ADC, and the gender difference in the likelihood of having the condition for a group was clear. Therefore, this study suggests the need to identify the group at a high risk of ADC on the basis of actual BMI status and perceived body image and to develop an appropriate mental health management program for the group.

The purpose of this study was to examine the health promoting behavior of university students and its related factors. A self-administered questionnaire survey was carried out for 1,031(male, 477, female, 554) students from 7 universities in Taegu from March 10 to April 15 2000. Collected data were analyzed by the $X^2$-test, t-test, ANOV A and structural equation modeling analysis. The results of this study were as follows; Mean score of health promoting behavior of women was higher than mean score of men(p〈0.01). According to the subordinate fields, female students showed significantly higher scores in the fields of stress management, nutrition, personal relations and alcohol-cigarette(p〈0.05). And in male students, the only fields of exercise had meaningfully higher score(p〈0.01). The highest degree of performance was marked in alcohol-cigarette field in female, and interpersonal field in male. In Both male and female students, the lowest field was health responsibility. The mean score of health promoting behavior showed significant differences in intermediating factors such as age, health education and grade in male, and such as grade, pocket money for a month, taking health education, perceived body shape and gastrointestinal symptoms in female(p〈0.05). The mean score of health promoting behavior showed significant differences in cognitive-perceptual factors and cues to action such as perceived health status, perceived benefits, perceived barriers, and health concern of parents in both male and female(p〈0.05). By the results of structural equation modeling analysis in male students, the economic status, gastrointestinal symptoms and perceived body shape as lean had significant direct effects on cognitive-perceptual factors($\mid$T$\mid$〉2.0). Grade and health concern of parents had significant direct effects on health promotion behaviors($\mid$T$\mid$〉2.0). In female students, perceived body shape as lean and perceived body shape as fat had significant direct effects on cognitive-perceptual factors($\mid$T$\mid$〉2.0). Grade, pocket money and health concern of parents had significant direct effects on health promotion behaviors($\mid$T$\mid$〉2.0). On the consideration of above findings, it is recommended that perceived health status and perceived benefits should be raised and perceived barriers should be lowered to increase health promoting behaviors, by means such as institutional approach which can enhance the primary prevention for a disease. In addition, the health policy for improving parents' concern about health as well as university students, through various ways such as health education, consulting, and health program, should be employed.

Objective: This study aims to identify important physical design variables in designing a necklace type wearable device, and to present design guidelines to maximize comfort that a user feels upon wearing the device. Background: Interests in fitness culture and personal health are on the rise recently. In such a situation, demand for necklace type wearable devices is projected to increase a lot, as the devices enable users to use their hands freely and to enjoy various contents through connection with mobile devices. However, the necklace type wearable device's comfort was assessed to have the lowest comfort in a running situation, where human body moves up and down and left and right more than other devices wearable on other human body parts. Therefore, the usability of a necklace type wearable device was low. In this regard, studies on identification of the variables affecting user comfort upon wearing a necklace type wearable device and on physical design direction maximizing comfort and usability are needed. Method: A pretest and a main test were carried out to draw the direction of necklace type wearable device design. In the pretest, wearing evaluation on the diverse types of devices released in the market was conducted to draw physical design variables of the devices affecting comfort. Furthermore, variables significantly affecting the comfort of a device were selected through an analysis of variance (ANOVA). In the main test, anthropometry was performed, and information on anthropometric items corresponding to the design variables selected in the pretest was acquired. Based on the pretest results and the anthropometric information in the main test, the present study produced design guidelines maximizing the comfort of a necklace type wearable device with regard to major design variables upon dynamic tasks. Results: According to the pretest results, the variables having effects on comfort were the angle of side points, width, and height. Due to interactions between variables, those need to be simultaneously considered upon designing a device. Upon dynamic tasks, the angle of side points and width of a device was designed to be smaller than mean angle of the trapezius muscle and neck width, and thus attachment to human body was high. As height was designed to be larger than mean neck front and rear point width, comfort was higher due to feeling of stability. Conclusion: Because user sensitivity to comfort was high at human body's inflection points, a device needs to be designed for users not to feel high pressure on specific body parts with the device fitting human body shape well. A design considering user's situation is also required in further studies.
