Purpose - This research examined the effect of hedonic and utilitarian eating-out motivations on the evaluation of restaurant selection attributes in a fashion premium outlet. Additionally, the influence of experimental and functional attributes on customers' preference for hedonic eating-out motives and utilitarian eating-out motives, and variation of moderating effects through the gender was examined. Research design, data, and methodology - A survey was conducted to verify the established research hypothesis. The questionnaire items for the research were modified to fit the situation of the present study. In order to elaborate the questionnaire, the literature of the previous researchers was reviewed and supplemented. The survey conducted 207 online questionnaires for consumers who have visited domestic fashion premium outlets from July 4, 2017 to July 27, 2017. A total of 207 questionnaires were collected, and a total of 206 questionnaires were used for the empirical analysis after excluding one inappropriate response. In order to verify the reliability and validity of the measured variables, exploratory factor analysis and reliability analysis were performed using SPSS 20.0. Next, the structural equation model (SEM) statistical method was used to test the hypotheses of the study. Results - Hedonic motivation had more influence on experimental attribute importance than the functional attribute importance of the restaurant. However, this result was different depending on the gender. The effects of hedonic motives on empirical attributes were more influenced by female groups, and when influencing functional attributes, male groups were more influenced. However, it was statistically significant (p <0.05) in the female group only when the hedonic eating out motives influenced empirical attributes. Conclusions - This study analyzed the effect of eating-out motivation on the restaurant preference attributes and suggested practical implications. First, customers with hedonic eating-out motivations were evaluating experiential attributes to be more important than functional attributes. Second, for customers who are motivated to use practical eating-out habits, companies should provide services that meet practical and economic needs. In particular, female customers visiting restaurants need differentiated marketing strategies that make them feel new experiences rather than practical ones. In addition, it is necessary to study more complex and integrated studies which will influence restaurant selection attributes of premium outlets customers by adding various eating out motives and selection attributes.

We surveyed the wearing characteristics of hip protectors. The problems of existing hip protectors were identified and the directions for improvement were presented. The evaluation of wearing characteristics was conducted on the 100 elderly women (60 to 85 years) with 5 types of hip protector. The questionnaire was composed of history and characteristics on falling, hip protector acceptance, preference, use characteristics and improvement requirements. The result of wearing characteristic evaluation indicated that 52% of the subject experienced falling in winter. Incidents resulting from falling occurred: outdoors (74.5%), bathroom (10.9%), and kitchen (5.5%). Body parts to be protected were in several areas: 35.6% for lumbar, 26.9% for hip joint, and 15% for hip bone. Participants prefer a belt B type design at a rate of 56.9% because it provided a sense of stability by clinging to the body and upholding the waist. Belt B type was the most appropriate in terms of fit, allowance, mobility, and design except pad thickness. To reduce the risk of hip fracture, hip protector needs to be designed in consideration of user's type of fall and body shape. The pattern and size of a hip protector has to be improved in regards to the amount of discomfort. An objective evaluation is needed for the ergonomic design of a hip protector based on and analysis of 3D body image of the elderly and the shock-absorbing quality of pad.

The purpose of this study is to analyze the general status of wearing clothes and clothing purchase of middle-aged women in the 40's to 50's, the patterns and colors of clothes they prefer, clothing preference related with fitting or such, and also complaints. And this paper also divides the middle-aged women into those in the 40's and 50's to analyze how they differ in terms of the apparel brands and fitting they prefer and also the status of wearing clothes. For the research, a survey was performed to 350 women, and the survey data went through x2 and t-test analysis by using SPSS 20.0 to examine significant difference. The results of this study are as follows: the women in the 40's included as the subjects showed a high frequency of clothing purchase from casual brands or SPA brands and regarded design to be important at the clothing purchase. Meanwhile, the women in the 50's indicated a higher frequency of clothing purchase of middle-aged women's apparel brands, outdoor brands, madam clothes, or designer brands and thought activity to be crucial at the clothing purchase. As the women in the 40's and 50's showed difference in the brands they preferred, particularly the fitting indicated difference in terms of dissatisfaction. While those in the 40's preferring and buying young casual showed particularly more fitting problems in the arm-hole girth, upper arm circumference, bust size, and thigh or hip area, those in the 50's indicated fitting problems in the hip circumference or waist measurement. It is expected that this study will be used as foundational data to set up the target age by related apparel companies or develop clothes with great size fitting and design satisfaction.

The objective of this study is to investigate the market of fitness compression wear as well as to design an optimal fitness compression wear by analyzing the muscle and movement characteristics of the elderly women in Korea. In this regard, research for functional garments is needed to increase muscle activity of elderly people during physical exercise. Firstly, we investigated the brand, design, size, material, and pattern of fitness wear based on the market survey. Secondly, we identified preference, evaluation items, evaluation method, and pattern design method based on the literature review. Finally, in addition, the motion type, range, angle to improve the muscle strength of the elderly were investigated and the maximum muscle strengths of each motion were analyzed by using 2007 Size Korea data (n = 386). It is also designed for muscle fatigue through exercise and rapid fatigue recovery after exercise. The evaluation methods for fitness compression wear were classified as motor functionality, physiological comfort, pattern and material suitability evaluations. The muscle strength at leg (pushing force) and waist (lifting force) of the ages of 60 to 69 years old showed 239.3 N and 274.5 N, respectively, which were the lowest forces compared to younger age groups. By applying these results to the design process of fitness wear, it is anticipated that the fitness wear will have a proper fit to the body shape of elderly people in South Korea as well as it can increase muscle efficiency to promote physical capability and healthy life for senior people.

본 연구에서는 Q방법론을 적용하여 대학생을 대상으로 학과 점퍼에 대한 주관적 평가와 인식 유형별 특성을 알아보고자 하였다. 대학생의 학과 점퍼에 대한 태도 및 인식유형은 3유형으로 분류되었다. 제1유형의 경우 학과 점퍼는 학과에 대한 소속감을 주고 학과를 홍보하는 역할을 한다고 인식하였다. 또, 학과 점퍼 착용 시 행동을 조심하지만, 활동이 편하고 주변 사람들의 좋은 평가를 하여 나의 신뢰감을 높여주는 효과가 있다고 생각하였다. 제2유형의 경우 학과 점퍼는 활동하기 편하며 유행을 따르지 않는 무난한 디자인이라 만족스럽고, 등교 시 늘 착용하였다. 제3유형은 학과 점퍼 착용 시 동질감과 소속감을 주고, 학과 점퍼가 유행을 따라가는 스타일이면 좋겠고 학과 점퍼 착용에 긍정적인 유형이다. 대학생들의 학과 점퍼는 유니폼으로 학과의 이미지나 상징성을 잘 나타내고, 활동량이 큰 대학생들의 신체적 특징을 반영하여 맞음새가 우수한 학과 점퍼가 개발되어야 할 것으로 생각된다.
