The purpose of this study is to investigate the importance of well-being related to lifestyle choices such as food habits, food choices, life pattern, etc. The survey was conducted among college students using a questionnaire and a 5-point Likert score in Seoul City and Kyunggido Province during September 2005. The responses of 968 college students were analyzed by the SPSS program. The results were as follows. Most of the subjects were female(76.2%), and lived with their parents (85.6%). The average score of 'food habits', 'choosing food materials', 'purchasing' and 'life pattern' were $2.71{\pm}1.22,\;2.86{\pm}1.28,\;2.41{\pm}1.21,\;and\;2.97{\pm}1.31$ respectively in males and $3.01{\pm}1.20,\;3.00{\pm}1.32,\;2.55{\pm}1.20,and\;2.68{\pm}1.40$ in females, respectively. In regard to 'food habits', the scores were significantly affected by gender(p<0.001), smoking(p<0.05), alcohol consumption(p<0.05), exercise(p<0.001), weight satisfaction(p<0.001), method of weight control(p<0.001), use of nutritional supplement(p<0.05), attempts at weight control(p<0.001), regularity of breakfast(p<0.001), level of interest in well-being(p<0.001), and whether the individual tried a well-being item(p<0.001). In regarding to 'choosing food materials' the scores were significantly affected by gender(p<0.001), smoking(p<0.05), exercise(p<0.001), weight satisfaction(p<0.05), method of weight control(p<0.05), use of nutritional supplement(p<0.05), attempts at weight control(p<0.001), regularity of breakfast(p<0.001), level of interest in well-being(p<0.001) ), and whether the individual tried a well-being item(p<0.001). Out of the factors affecting 'purchasing', the association with BMI was remarkable. Students who were overweight, obese or underweight showed higher average scores than students of normal weight. The primary concerns and trial of well-being of college students were food and exercise. Therefore, the purchase of well-being goods is related to their weight control in college students. In regard to 'life pattern' the scores were significantly affected by exercise(p<0.01), use of computer(p<0.001), BMI(p<0.001), weight control(p<0.001), use of nutritional supplement(p<0.05), regularity of breakfast(p<0.001), level of interest in wellbeing(p<0.001), whether the individual tried a well-being item(p<0.001), and having taken lecture on well-being(p<0.05). Therefore nutrition education is needed for healthy eating habits of college students and it is necessary to develop a series of lectures to teach them about diet and exercise programs.

본 연구는 서울지역 20-50대 성인 남녀 161명을 대상으로 코스메슈티컬 화장품에 대한 인지 및 만족도를 조사하고 소비자들을 위한 개선 사항을 분석하여 향 후 마케팅 전략을 위한 기초자료를 제공하고자 하였다. 코스메슈티컬이라는 생소한 용어 때문에 40대 이 후 연령에서는 인지도가 떨어지지만 병원에서 사용되는 전문성, 의사의 권유, 과학적인 이미지로 많은 소비자들이 선호하는 것을 알 수 있었다. 전체 49.85%의 사용자 중 94.41%가 재 구매의사를 밟혀 매우 만족도가 높음을 알 수 있고, 50.15%의 비사용자 중 향 후 구매 의사를 밝힌 응답자가 72.22%에 해당하였다. 피부지식도가 높을수록 화장품에 대한 관심과 미적 실천율이 높았으며, 제품을 선택 할 때는 피부지식도가 높을수록 비사용자는 브랜드 인지도(r=.222, p<.05)와 성분(r=.245, p<.005)을 많이 고려함을 알 수 있었고 사용자는 피부지식도가 높을수록 사용의 용이성(r=.162, p<.05)을 중시하는 것을 알 수 있다. 따라서, 아직은 코스메슈티컬 화장품에 대한 전체 소비자들의 인지가 높지 않으므로 지속적인 홍보와 재 구매 요인 강화 및 일반화장품과의 차별화 전략이 필요 할 것으로 생각된다.

날개 없는 선풍기는 특유의 형태로 인한 안전성과 청소의 간편함, 심미성으로 제품화에 성공하였다. 그러나 기존 선풍기에 비해 약한 바람과 모터에 의한 소음과 같은 단점은 구매력을 감소시키는 주요인이며, 따라서 모터의 속도를 증가시키지 않고 바람의 세기를 증가시키는 방안이 필요하다. 본 연구에서는 질량유량에 영향을 주는 인자, 수준을 선정하고 이를 실험계획법인 직교배열표를 이용하여 실험점을 배치하였다. 질량유량의 값은 전산유체해석 프로그램인 ANSYS FLUENT를 사용하여 질량유량의 값을 확인하였으며, 평균분석을 통해 질량유량에 가장 큰 영향을 주는 인자는 노즐 간격임을 확인할 수 있었다. 또한 예측 모델 식을 통해 얻은 질량유량의 값과 전산유체해석의 질량유량의 값이 가장 큰 값으로 일치하는 것을 나타내었다. 본 연구를 통해서 모터의 속도를 증가시키지 않더라도 형상 변화를 통해 질량유량의 증가시킴을 확인할 수 있었다.

The purpose of this study was to estimate usage of vitamin and mineral supplements as over-the-counter (VM-OTC) drugs as well as examine factors associated with VM-OTC usage in Korean adolescents. A total of 1,407 adolescents attending middle or high school in all parts of country were included in the analysis. Prevalence of VM-OTC usage was 56.1%, and it was higher as monthly income, father's education level, and socioeconomic status of family increased (p<0.001). VM-OTC intake was higher in middle school students than in high school students as well as in rural areas or small & mediumsized city residents than big city residents (p<0.01). Subjects mainly received information on VM-OTC mainly from 'family and relatives' (46.6%), whereas only 20.3% received information from experts. Subjects took VM-OTC 'when they are healthy' (49.1%), 'when they feel sick' (17.7%), 'when they are on a diet' (17.3%), and 'when they are stressful' (15.9%). The effectiveness of taking VM-OTC were mainly 'fatigue recovery' (35.0%), 'health improvement' (30.6%), and 'nutritional status improvement' (13.2%). The most frequently used VM-OTC was vitamin C (49.1%), multi-vitamins (18.6%), multi vitamins & minerals (13.2%), and calcium (9.2%). Among VM-OTC users, only 21.9% replied that they usually check the nutrition facts when they buy products, 62.4% follow the recommended dosage, and 9.7% fully understand the nutrition labels of the products. According to logistic regression analysis, the most influential factor affecting VM-OTC use was parents' and siblings' VM-OTC consumption (p<0.001). In addition, school type (middle or high school) (p<0.01), residence (p<0.05), self-concerns about health (p<0.05), father's education level (p<0.05), and socioeconomic status of family (p<0.05) all influenced VM-OTC use. These results show that VM-OTC use is widespread among adolescents, few users actually check and fully understand the nutrition labels when they purchase VM-OTC, and they are highly dependent on unprofessional advice and information. Therefore, it is necessary to educate adolescents to help them select proper VM-OTC and read nutrition labels.

Purpose - Despite the importance of price, many companies do not implement pricing policies smoothly, because typical price management strategies insufficiently consider logistics efficiency and an increase in logistics costs due to logistics waste. This study attempts to examine the effect of product line pricing, which corresponds to product mix pricing, on logistics efficiency in the case of manufacturer A, and analyzes how logistics performance changes in response to these variables. Research design, data, and methodology - This study, based on the case of manufacturer A, involved research through understanding the current status, analyses, and then proposing improvement measures. Among all the products of manufacturer A, product group B was selected as the research object, and its distribution channel and line pricing were examined. As a result of simulation, for products with low loading efficiency, improvement measures such as changing the number of bags in the box were suggested, and a quantitative analysis was conducted on how these measures influence logistics costs. The TOPS program was used for the Pallet loading efficiency simulation tool in this study. To prevent products from protruding out of the pallet, the maximum measurement was set as 0.0mm, and loading efficiency was based on the pallet area, and not volume. In other words, its size (length x width) was focused upon, following the purpose of this study and, then, the results were obtained. Results - As a result of the loading efficiency simulation, when the number of bags in the box was changed for 36 products with low average loading efficiency of 73.7%, as shown in
