  • 현재 디자인 분야에서는 감성에 관한 강한 필요성을 바탕으로 오감각과 인간의 의식 속에 잠재되어 있는 감성적 요소를 디자인에 반영하려고 노력하고 있다. 그러나 그러한 감성적 의미를 표현하기 위한 체계적인 연구에는 아직 미흡한 점이 많으며, 특히 오감각 중 시각적 요소를 중심으로 한 디자인반영과 한정된 연구가 이루어지고 있다. 이러한 한계점을 극복하고 새로운 디자인과 감성적 이미지를 표현하기 위해서는 타 감각적 요소에 대한 깊이 있는 연구와 디자인에 접목시킬 수 있는 실증적 대안이 필요하다. 본 연구에서는 그러한 감성 이미지를 표현하기 위한 감각요소 중 촉각적 요소를 중심으로 연구를 진행하였으며, 현대인의 소비 행태에 있어서, 감성적 디자인 요소로서 촉각적 요인과 밀접하게 관련된 핸들 커버와 음료병 제품의 재질, Grip감, 형태 등이 선호요인으로 작용하는 정도를 알아보았다. 동시에 두 제품군의 각각 선호도와 제품의 촉각적 특성 관계를 비교한 결과 기능적 특성과 원인에 따라 디자인의 촉각적 선호요인의 차이를 보였고, 이는 디자인 시제품 카테고리별 선호 촉감 요소의 차별적 반영이 필요함을 알 수 있었다.

  • In order to identify the factors responsible for the recent drastic increase of imported apparel in Korea, an attempt was made to determine the variables influencing the purchasing behavior of imported and domestic apparel and forecast the purchasing intention with the use of Fishbein & Ajzen's behavioral intention model including both attitude and subjective norm. Based on literature review, the empirical study was conducted using the questionnaire for 900 college women and high school girls living in Seoul. Descriptive statistics, t-test, paired-t test, multiple regression analysis, and correlation analysis were made of 771 returned questionnaires using SAS program. The results were as follows : First, the results of assessing both their attitudes toward imported and domestic apparel and their subjective norms were shown to be different. Second, there was a difference in the attributes that had an effect on their attention to buy imported and domestic apparel. Third, those respondents having a preference for imported apparel were most highly influenced by color and price. While those respondents showing a preference for domestic apparel were most highly influenced by materials and comfortableness. Fourth, the validity of the prediction value of their buying intention was confirmed as it was shown to be more than coreelation coefficien r=0.65. In conclusion, 1) it was proved that both attitude and subjective norm were the important variables that could predict the consumer's purchasing intention, 2) since competitiveness in color and materials and brand influencing the consumer's purchase of and preference for domestic apparel relatively lagged behind in comparison with that of imported apparel, the domestic apparel business enterprise will have to make a greater effort to develop differentiated color, material and prestigious brand so as to enhance competitiveness with imported apparel.

  • Currently, the global furniture market can not overlook environmental problems due to changes in environmental regulations. In order to grow into a global corporation, environmentally friendly design became essential. In addition, domestic and foreign consumers are increasingly interested in and spending on children's furniture, and demand for environment - friendly furniture for children's health and emotional development is increasing. In the era of universal consumer tastes due to massive mass production, it has been changed into a multi-product small-volume production period that reflects the preferences of various consumers, so that various types of furniture that meet individual preferences are required. Therefore, in this study, we investigated various personal opinions, perception, preference, propensity to use furniture, purchasing points, etc. for environmentally friendly children's furniture, and provided basic data for environmentally friendly children's furniture development that reflects consumer preference and requirements. Accordingly, 243 parents who have more than one child living in Seoul, Gyeonggi, and Incheon were surveyed about the use of children's furniture and the perception and preference of environmentally friendly children's furniture. According to the survey results, 64.57% of the respondents knew about eco - friendly children's furniture and the most popular way to get to know eco-friendly furniture was Internet advertising (49.48%). The rate of recognizing eco-friendly furniture as healthy furniture with no emission of hazardous substances was high as 56.16%. The purchase intention of eco-friendly children's furniture was very high at 86.01% and the most important factor in purchasing was the harmlessness to the human body (56.88%). 59.50% said that it is not possible to distinguish environmentally friendly furniture, which means that there is not much information to consumers yet. In addition, the preferred price range is 500~1000 thousand won, and the preference for the rest furniture is high. In the preferred form type, unit type modular furniture is 36.13%, in the material, wood is 72.35%, in the color, the color of wood with wood grain is high as 45.56%.

  • The aim of the study was to explore the current status as well as personal views, attitudes, and beliefs regarding daily meal consumption (DM) and food supplement use (FS) in conjunction with the improvement of health condition of the women. Eight focus group interviews were performed and the interview material was condensed systematically with the aim to extract core meanings related to DM, FS, and menopause-associated health. Participants were 40 in number and showed ages ranging from 45 and 60 years with various menopausal status. Current status and beliefs about DM, resources of purchase motivation of FS, types of FS that are currently used, and perceived effects and personal beliefs about FS are discussed. Theme content analysis revealed 3 themes for beliefs about DM, 5 themes for beliefs pertaining FS, and 4 themes for the association between DM and FS. Non-dietary factors such as positive mental attitude and exercise appeared to be also important to maintain good health. The bottom line message from this study may be that proper nutrition through daily meals is essential for good health, while food supplement are used merely to supplement the diet. Findings from this study may deepen our understanding of how women who translate their lifespan through "menopause" perceive the roles and meaning of DM and FS, suggesting health professionals need to monitor and evaluate DM and implement strategies targeting the improvement of daily meal quality of middle and older aged women.

  • This study investigates the wearing trend and purchase facts for adult females in their 20s and 30s along with their fitting satisfaction for woven jackets and circular knitted jackets. A questionnaire survey on consumers investigated satisfaction with jackets according to clothing materials and repair trend after wearing. Subsequently, a preference for circular knitted jackets was shown higher than woven jackets. Females in their 20s preferred woven jackets than those in their 30s; however, the latter preferred circular knitted jackets than the former. For woven jackets, they showed the highest satisfaction with size; however, for circular knitted jackets, they showed the highest satisfaction with fitting. In the question on their satisfaction by jacket part, satisfaction with circular knitted jackets was higher in all items except for bust measurement, bottom edge measurement, elbow circumference, shoulder width, and clothes length. Circular knitted jackets had lower repair rates than woven jackets and woven jackets had significant differences by age in satisfaction with back width. The research results indicate that females in their 20s and 30s who value fit preference and practicality will increasingly wear knit clothes. Therefore, we can address the fitting satisfaction requirement of females in their 20s and 30s by taking the clothing material properties of circular knitted clothes into consideration. In addition, further research is required on jacket patterns in consideration of clothing materials.

  • This study aimed to determine the feasibility of survey questionnaires for pesticide poisoning. We conducted a pilot study to develop a questionnaire for evaluating pesticide poisoning symptoms and to examine the validity of self-reported information for individual pesticides used. In December 2010 we interviewed 20 farmers with self-reported pesticide poisoning histories residing in Gyeonggi Province. For validity of pesticide information, the purchased pesticide lists from the agricultural cooperative federation were compared with individual self-reported pesticides used. Neurological symptoms were the most common among clinical symptoms related to pesticide poisoning, followed by gastrointestinal, dermal and eye symptoms. Insecticides were the main causative pesticide class for poisoning. Twenty one major symptoms were selected for screening for acute pesticide poisoning in a field study based on the pilot results and literature reviews. Substantial under-reporting was found in data on self-reported individual pesticides used (9.2%), as well as low accuracy (36%) compared with their actual purchase lists. In this pilot study, we suggest the selected symptom lists may apply to a field survey of pesticide poisoning. However, the self-reported information on individual pesticides may not be valid and alternative methods need to be developed.
