  • The purposes of this study was to demonstrate the influence of fashion life-style, self-image and situational factors on consumer's apparel store choice for satisfaction of varied needs and high efficiency of marketing activity. A questionnaire was developed to measure research subjects based on theoretical study empirically. The questionnaire was administered to 270 women aged between 20 and 30 in Seoul. The results analyzed by factor analysis, cluster analysis, x2-test and oneway-anova. The results of empirical studies were summarized as follows: 1. Segmented groups of fashion life-style were classified practical/planning group, fashion- leader group, and shopping-oriented group. And store types which were prefered by those groups were department store/shopping center. 2. Segmented groups of self-image were classified actual-seeking group, modernity group and confidence group. And store types which were prefered by those groups were department store/shopping center. The Forecast of store choice on the base of self.image was showed that customers choose the store incongruous with self-image. But when it was analyzed each actual store choice. The Choice of high frequancy was congruous with self-image except for a specialty store/brand named outlet. 3. The significant differences could be found in choice of the store under particular purchase situations and especially at department stores and specialty store, their preference tended to be stronger as the degree of the store's involvement was hightened, but in the case of the generalization stores and the permanent discount stores, even though the degree of that involvement was low, their preference showed the same tendency.

  • This study surveyed 266 housewives residing in a Gyeonggi-provincial area for their dietary attitudes, dietary habits, nutrition knowledge, and application of nutrition information to daily life according to whether they use nutrition labeling. The survey on the dietary attitudes of the subjects showed that the points of "think that nutrition affects health", "quite interested in nutrition and health information", "like developing and trying new diverse recipes", and "persistently try new foods" were higher among those who check out nutrition labeling (Check group, n=112) than those who do not check out nutrition labeling (No check group, n=154). Reason for snacking, the Check group reported higher in the reasons of "for taking nutrients" but lower in the reasons of "do not eat enough meal" and "impulsively" than the No check group (p<0.01). Asked about why they check the nutrition labeling, the Check group answered "to compare products with each other" and "to purchase healthy food" whereas the No check group said "to decide whether the food is safe or not" and "to reduce body weight" (p<0.01). The Check group showed more recognition on the significance of the nutrition labeling and application to their actual daily lives than the No check group. Therefore, our results suggest that proper use of nutrition labeling is expected to improve dietary attitudes and dietary habits as well as enhance the application of nutrition information to actual daily life and promote health not only for the housewives but also for their family members as well.

  • 최근의 사회는 매우 빠르게 변화하고 있으며 이로 인해 비장애인뿐만 아니라 장애인의 삶을 더욱 어렵게 하고 있다. 장애영역 확대로 인한 장애인구의 증가와 가족구조의 변화 등에 따라 장애인 복지 수요가 지속적으로 증가하고 있으며, 장애개념에 대한 변화와 자립생활에 대한 확산 그리고 무엇보다 장애인 인권의식 신장 등 장애인복지를 둘러싼 환경과 패러다임이 급속히 변화하고 있다. 노동권은 인간의 삶에 있어 생계는 물론이고 사회참여와 자아실현이라는 삶의 가치부여에 있어 아주 중요한 부분이며 장애인복지 패러다임인 자립생활을 가능하게 하는 핵심이기도 하다. 이에 본 연구는 청주시 중증장애인의 근로욕구 및 실태를 조사하여 향후 중증장애인의 욕구와 청주시특성에 맞는 일자리창출 및 중증장애인 고용 기회 확대 방안을 제시하고자 한다.

  • 본 연구는 실제 생활시 주거 건물에서 발생하는 바닥충격음과 유사한 반복적인 충격원을 개발하려 시도하고, 이렇게 개발되는 새로운 충격원에 대응하는 평가 방법을 찾기 위해 수행되었다. 새로운 충격원을 개발해야 하는 필요성은 실제 주거 건물에서의 바닥충격음과 관련된 문제가 주로 어린이의 뛰는 소리에서 비롯되기 때문이다. 그러나 바닥충격음을 측정하고 평가하는 데 사용된 표준 충격원은 단일 충격 형태로, 실제 생활에서 문제가 되는 충격원과는 다른 특성을 가진다. 연구를 위해 18개의 평가 항목을 도출하였으며, 항목에 대한 설문조사 및 청취실험을 통해 바닥충격음을 평가하는 데 적용 가능한 항목으로 심리적 영향(신경쓰임, 화가 남), 일상 생활 방해(수면 방해, 휴식 방해) 및 생리적 영향(혈압 상승) 항목을 제시하였다. 이들 항목은 개별적으로 활용될 수 있으며, 바닥충격음 평가의 유형에 따라 선택적으로 활용할 수도 있다. 이를 통해 실험실에서 청취 실험의 포괄적인 평가나 바닥충격음과 관련된 주거 환경에서의 소음 평가를 더 체계적으로 수행할 수 있을 것이다.

  • Purpose: The purpose of this article is to clearly describe research trends on health life expectancy using oral health indicators that have been published from 2010 to 2020 then suggest the direction of future research. Methods: Online academic databases in English (PubMed, Web of Science and Embase) were used to find those articles by applying a variety of keywords, including terms (adjusted life year, adjusted life expectancy, dental and oral). We identified relevant articles based on the following classification method of Mathers: (1) health gaps, (2) health expectancies. Results: Among 1,728 articles from the online databases, the final 13 studies satisfied the inclusion criteria and were selected for analysis. Health life expectancy studies indicate that research growth was recently achieved overseas. Among the literature collected in this study, 10 studies using health gap indicators yielded seven Disability-Adjusted Life Year (DALY), and three calculated Quality-Adjusted Life Year (QALY), which differed in the nature of the survey data used in the study measuring DALY and QALY. There are only three health expectancies and the number of papers were smaller than the health gap study. Conclusion: Establishing a foundation to calculate health life expectancy indicators through the development and improvement of oral health level are needed. More studies in the area of health life expectancy estimation research is based on actual prevalence and oral health-related quality of life are also needed.

  • This paper investigates the correlation between strip surface roughness and the surface of the work roll. As the actual temper mill(TM) is used, this data will be adopted to another actual temper mill for the application and operation of this experiment. Conclusions are as follows: Electro-discharge texturing(EDT) roll has homogeneous roughness distribution and shape, and also a sinuous peak surface and the life is 2 times longer than that of shot blast texturing(SBT) method. And the higher surface roughness of work roll, the more time is necessary at the EDT method. In the SBT method without the correlation of roughness, but impeller rotation speed with an uncontrollable peak count. The roughness of SBT roll is irregularity compared to that of EDT roll because the work roll roughness is transferred to the strip which was temper rolled, and produces a more desirable image and greater clarity to the color painted steel sheet.

  • The corrosion forms of automotive body panels are various. One of the representations is a corrosion pitting and its propagation on the lapped portion by galvanic corrosion. But it has been difficult in correlation analysis about the corrosion propagation rate and mechanism of pitting and the actual automotive body in field. This present study interprets experimentally the rust pitting occurrence mechanism on the lapped panels through experimental methods. And field car investigation was executed for correlation analysis with experimental results. This paper compares corrosion propagation rate by pitting on hot-dip galvannealed steel sheets with corrosion forms in the automotive field condition. The research fundamentals which make it possible to predict the pitting occurrence and propagation on the lapped panels in the actual vehicles are given.
