This study was conducted to investigate the recognition, utilization, preference and application of kimchi, as well as to evaluate the recognition and requirement for commercial kimchi to university students. A questionnaire was answered by 180 (44.0%) male and 229 (56.0%) female university students in Daegu. The methods used to analyze the items were frequency analysis, Chi-squared tests and t-tests. Most of the respondents reported that they liked kimchi and had a preference for ripened kimchi In addition, most students were likely to cook kimchi by pan-broiling which indicates that the development of kimchi designed for pan-broiling may lead to an increase in the intake of kimchi. The recognition and utilization of commercial kimchi abutted through wholesale market very much, and were buying The marketing points that could most increase the sales of kimchi appeared to be 'hygiene' and 'standardization of taste and ageing' for male students 42 (23.7%) and 'hygiene' for female students 94 (41.4%) (p<0.01). All students responded that among marketing techniques for the sale of kimchi, diversification of taste, and increasing the recognition of kimchi were the most important parameters for aggressive globalization of the sale of kimchi. Therefore, the consumption of kimchi will increase in response to changes a dietary life style and activation is a plan getting done, and it is thought consumption of a kimchi to reflect these results well.

Recent research reported that perception of future time is non-linearly scaled. That is, as objective time gets longer, subjective perception of the objective time does not grow proportionally. The non-linear time perception implies that the same future time feels shorter when it starts in the future than when it starts immediately. The authors call this as a future contraction effect. The current research tests two important implications of the effect regarding consumers' intertemporal preference for durable goods. First, consumers who contract future more will be more impatient for durable goods compared to those who contract less because the former would feel to use the same durable goods longer when it is purchased immediately. Second, consumers' impatience will be alleviated when their tendency to contract future is reduced. The authors find support for these predictions through two studies. Taken together, the current research demonstrates a property of time perception that has important ramifications for understanding consumers' intertemporal preference for durable goods.

Purpose - With the increase in fervor to purchase luxury brands, new social problems have arisen, such as excessive preoccupation with luxury brands and high preference for forged luxury goods. Therefore, the issues related to luxury brands, termed "Luxury Syndrome," have emerged as an area of great interest for researchers and practitioners. However, previous studies neglect to categorize this preference for luxury brands. Therefore, this study aims to identify the different purchasing behaviors of consumers using the types of luxury brands preferences as parameters. Research design, data, and methodology - This study arranges a causal relationship model assuming that purchase behaviors positively (+) affect typified preference for luxury brands and purchase intentions. We administered a questionnaire survey to the purchasers who bought luxury brands from department stores to secure additional data necessary to verify the hypotheses in this study. We then processed the data using SPSS 19.0. We further analyzed the basic data using frequency and descriptive statistical analysis, and verified the measurement tools through feasibility and reliability analyses. Moreover, this study uses multiple regression analysis to verify the hypotheses. Further, this study tests the path effect between luxury brand purchase attitude and purchase behavior, with non-intrinsic preference and intrinsic preference as the mediating variables. Results - Based on the results, the impact of tendencies of conspicuous consumption and self-monitoring on non-intrinsic preference was significantly positive (+), while the impact of tendencies of pursuit of a reference group, conspicuous consumption, and self-monitoring on intrinsic preference and purchase intentions was significantly positive (+). Further, non-intrinsic and intrinsic preferences positively (+) influence purchase intentions and the impact of non-intrinsic preference took an absolute portion. However, the tendency of dependence on brands negatively (-) impacts purchase intentions. The results showed that self-monitoring and conspicuous consumption tendencies have greater effect on purchase intention, which is mediated by non-intrinsic preference. In contrast, reference group following tendency has a greater effect on purchase intention, which is mediated by intrinsic preference. Conclusions - Based on the results, the study verifies that the consumption of luxury brands in Korea has not yet entered the settling period. The tendency for conspicuous consumption and the tendency for pursuit of the reference group were relatively important aspects for the consumers who prefer luxury brands non-intrinsically and intrinsically, respectively. Especially, it was found that the purchase intentions for forged brands originate from the tendency to depend on brands. Based on these findings, this study suggests the measures to develop and mature the luxury brands market, and reinforce marketing performance at the three levels, that is, government, distributors, and manufacturers. The luxury brands manufacturers should devote themselves to the production and design of products to catch the attention of mature consumers of luxury brands. The luxury brands distributors should then raise the level of Customer Relationship Management (CRM) for opinion leaders. Finally, the Government should prepare effective policies for the development of luxury brands and provide a variety of economic support.

This study was conducted to estimate the drift of change for kimchi purchase, and to contribute to quality improvement of kimchi sold at markets. Questionnaries were distributed to 450 adults and 396 were statistically analyzed. The methods used to analyze the items were frequency analysis, Chi-square, t-tests and ANOVA. The highest preference for kinds of kimchi was Beachoo kimchi, while the preference for Nabak kimchi was low. In terms of the degree of ripening, most subjects preferred properly ripened kimchi. With regard to the purchase amount the subjects preferred 1 kg and mainly purchased it once every three months at large market and supermarkets. The main reason for purchasing kimchi at markets was 'convenience', while the reason they didn't purchase it was 'it might contain artificial seasoning'. With regard to the development and improvement of the kimchi industry, the subjects belived that taste and ripening should be standardized, and that kimchi should be treated sanitarily. They acknowledged that kimchi products should be diversified, and active marketing should be carried out in order for it to be globalized.

There have been many studies to build a model that can help investors construct optimal portfolio. Most of the previous models, however, are based upon the path-breaking Markowitz model (1959) which is a quantitative model. One of the most important problems with that kind of quantitative model is that, in reality, most of the investors use not only quantitative, but also qualitative information when they select their optimal portfolio. Since collecting both types of information from the markets are time consuming and expensive, making a set of target assets smaller, without suffering heavy loss in the rate of return, would attract investors. To extract only desired assets among all available assets, we need knowledge that identifies investors' preference for the risk of the assets. This study suggests two-layer decision-making rules capable of identifying an investor's risk preference and an architecture applying them to a quantitative portfolio model based on risk and expected return. Our knowledge-based portfolio system is to build an investor's preference-oriented portfolio. The empirical tests using the data from Korean capital markets show the results that our model contributes significantly to the construction of a better portfolio in the perspective of an investor's benefit/cost ratio than that produced by the existing portfolio models.

The purpose of this study was to examine the effects of the structural characteristics of men's suit fabrics on the texture image and the preference, and to analyze the relationship between the preference and the practical sales ratio. In addition, the texture images and the preference of fabric and jackets made of the same fabrics were compared. As specimen, jackets for men's suit of 2002' S/S and their fabrics were collected. Questionnaires composed of 22 sensibility related and 21 fabric image related adjectives were developed. For the subjective evaluation of the texture image, both jackets and fabric samples were tested. Tests were performed with 100 female subjects in clothing department and apparel industry. For the objective evaluation, structural characteristics such as fiber contents, yarn twist, fabric count, thickness and weight were analyzed. Total Hand Value were calculated from mechanical properties determined by the KES-FB system. Factor analysis showed sensibilities were classified into 6 categories; "surface roughness", "weight", "density", "stiffness", "elasticity" and "wetness". Fabric images were classified into 4 categories; "classic", "original", "practical", and "stuffy". Depending on the method to show the specimen to the subjects, whether it is suit or fabric, statistically significant differences were observed with a number of adjectives for sensibilities and fabric images. The results of THV of KES did not agree with the preference of subjects, which suggests that we should be careful when using the KES system, which was developed for Japanese people. Price was considered to be another factor besides the texture image that influenced on purchase.

Nicotine addiction is a worldwide problem. However, previous studies characterizing the rewarding and reinforcing effects of nicotine in animal models have reported inconsistent findings. It was observed that the addictive effects are variable on different factors (e.g. route, dose, and age). Here, we evaluated the rewarding and reinforcing effects of nicotine in different routes of administration, across a wide dose range, and in different age groups. Two of the most widely used animal models of drug addiction were employed: the conditioned place preference (CPP) and self-administration (SA) tests. Nicotine CPP was evaluated in different routes [intraperitoneal (i.p.) and subcutaneous (s.c.)], doses (0.05 to 1.0 mg/kg) and age [adolescent and adult rats]. Similarly, intravenous nicotine SA was assessed in different doses (0.01 to 0.06 mg/kg/infusion) and age (adolescent and adult rats). In the CPP test, s.c. nicotine produced greater response than i.p. The 0.2 mg/kg dose produced highest CPP response in adolescent, while 0.6 mg/kg in adult rats; which were also confirmed in 7 days pretreated rats. In the SA test, adolescent rats readily self-administer 0.03 mg/kg/infusion of nicotine. Doses that produced nicotine CPP and SA induced blood nicotine levels that corresponded well with human smokers. In conclusion, we have demonstrated that nicotine produces reliable CPP [0.2 mg/kg dose (s.c.)] in adolescents and [0.6 mg/kg dose (s.c.)] in adults, and SA [0.03 mg/kg/infusion] in adolescent rats. Both tests indicate that adolescent rats are more sensitive to the rewarding and reinforcing effects of nicotine.

Propofol is an anesthetic commonly used to provide sedation or to induce and maintain an anesthetic stated. However, there are reports which indicate propofol may cause psychological dependence or be abused. In the present study, we used various behavioral tests including climbing test, jumping test, conditioned place preference, and self-administration test to assess the dependence potential and abuse liability of propofol compared to a positive control (methamphetamine) or a negative control (saline or intralipid). Among the tests, the conditioned place preference test was conducted with a biased method, and the selfadministration test was performed under a fixed ratio (FR) 1 schedule, 1 h per session. No difference was found in the climbing test and jumping test, but propofol (30 mg/kg, i.p.) increased the rewarding effect in the conditioned place preference test, and it showed a positive reinforcing effect compared to the vehicle. These results indicate that propofol tends to show psychological dependence rather than physical dependence, and it seems not to be related with dopaminergic system.

현대 사회는 TV, 잡지, 신문, 인터넷 등 다양한 매체를 통해 이미지를 접할 수 있으며, 이렇게 접하는 이미지들은 의식적으로 또는 무의식적으로 사람들의 삶과 인식에 결정적인 영향을 미친다. 과거의 이미지 생산 매체들은 장면을 물리적으로 동일하게 재현하는데 주된 목적이 있었던 반면, 최근에는 인지적 선호도에 의한 재현이 중요하게 인정받고 있으며, 사진의 선호도는 TV, 잡지, 신문, 인터넷 등 주변에서 접하는 시각적 콘텐츠의 영향을 받는다. 최근 이미지를 생산하는 재현 매체로서 가장 중요하게 사용되고 있는 장비를 디지털 카메라이다. 디지털 카메라의 이미지를 형성하는 핵심은 ‘빛’인데, 빛의 양, 즉 노출의 조절을 통해 이미지를 형성하게 된다. 현재 디지털 카메라는 물리적으로 정확한 재현을 목표로 노출을 조절하도록 설정되어 있는데, 물리적으로 정확한 조절이 반드시 인지적으로 선호도가 높은 조절은 아니다. 따라서 물리적으로 정확한 노출 설정이 아니라 인지적으로 정확한 노출 설정을 찾기 위한 실험을 진행하였다. 특히 인지적으로 색상과 농도 변화에 가장 예민한 피부톤을 기준으로 실험을 진행하였으며, 성별에 따라 노출 선호도가 다를 수 있으므로 남성과 여성 모델을 각각 촬영하여 자극에 사용하였다.
