자동차에서 실내음질은 구매결정 요소들 중의 하나로 그 중요성이 점차 증가하고 있다. 따라서 다양한 운전조건에서 운전자가 기대하는 실내음질의 기대 수준을 충족시켜야 한다. 소비자는 운전경험과 습관에 따라 기대하는 음질에 차이가 있고 소리에 대한 표현방식도 모호하기 때문에 이러한 주관적 특성을 하나의 통일된 표현으로 정의 하기가 어렵다. 그러나 지난 이십여 년 동안의 음질개발과 차량 실내소음 주관평가의 통계처리로 통일된 표현을 할 수 있었다. 나아가 심리음향학 및 신호처리기술의 발달과 꾸준한 음질연구결과로 소리특성을 객관적으로 나타내는 소리의 시각화가 가능하였으며, 운전자가 인식하는 주관평가와의 상관관계를 높여 차량의 대표적인 음질인자로 정량화하여 음질목표를 설정할 수 있었다. 실내소음의 구성은 엔진 투과음, 흡배기 소음, 바람 소음, 도로 기인 소음 등으로 다양하므로 소음원에 따라 음의 균형을 맞추어 조화로운 음질개발을 하는 것이 중요했다. 또한 차량 판매되는 지역에 따라 선호음이 상이하여 지역별 실내음질의 차별화가 필요했다. 궁극적으로는 운전자의 감성품질을 만족할 수 있도록 음을 제어하여 브랜드 사운드를 개발하고 있다. 이러한 실내음질을 달성하기 위한 방법으로 소음원과 전달경로에 대해 기여도를 분석하고, 경로를 구성하는 시스템 별로 세분화하여 시스템 목표를 설정하였다. 시스템 개발에 중요한 인자로 차량의 동강성 및 흡차음 성능을 들 수 있다. 특히 디젤차량의 비중이 큰 유럽업체의 차량의 동강성 및 흡차음 개발 능력은 높게 평가되고 있다. 이에 유럽의 부품전문회사가 가지고 있는 해석과 시험적인 개발 방법을 통하여 전달계 특성을 만족하기 위한 시스템의 동강성 및 흡차음 특성을 개발하고 있다. 차량음질 튜닝의 중요한 기법 중 하나로 흡배기 개발을 추진하고 있다. 친환경자동차인 하이브리드차량, 전기차량 및 연료전지차량의 경우 전기구동부품에서 발생하는 각종 이음 발생을 최소화 했다. 보행자를 보호하고 운전의 즐거움을 향상하기 위한 가상사운드 개발을 진행하고 있다. 회사 수익성 향상을 위한 원가절감 및 구조 경량화에 따른 음질악화와 연비 향상 및 배기가스 규제 강화로 고성능 고출력 엔진탑재에 따른 음질악화 요인을 극복해야 했다. 운전자의 청감은 차량의 운전성에 따라서도 크게 영향을 받게 되므로 엔진제어와 변속기제어를 통해 음질과 운전성이 조화를 이룰 수 있도록 개발하고 있다. 향후, 소음원에 따른 시스템 최적화 개발, 운전성과 음질 연계 개발과 친환경차량의 가상사운드 개발 등이 자동차 음질 개발의 중요한 이슈로 생각한다.

For changes in the distribution structure these days, consumer demand is moving rapidly from offline to online. The consumers' mentality to purchase products conveniently is reflected in this phenomenon. Also for agricultural products, safety to protect contents, brand and design which can provide credibility to consumers are recognized as most important than ever. Especially, strawberry is thin-skinned so that the quality of product may deteriorate even with weak impact and shaking, so it is significantly influenced by the structural packaging or material. Also, strawberry is frequently distributed through direct trading, it is the reality that the package design of strawberry is less competitive than that of other products due to inadequate environments of commercial farms. That is, the demand of strawberry increases everyday but the strawberry package cannot fulfill the needs of producers and consumers. In order to reinforce competitiveness in strawberry sales, it is urgent to carry out fundamental studies regarding the development of package. Therefore, the purpose of this study is to supplement and improve issues arising from the usage of current strawberry package. Through the analysis of strawberry package elements (shape, material, design) and understand the points of improvement sought by producers and consumers through IPA MAP (importance, satisfaction level) analysis.

This research investigates the causal relationships between the selection attributes of coffee shops and customer value and revisit intention. To do this, the statistics programs SPSS 18.0 and AMOS 18.0 were used targeting 218 college students from three universities (K, D, Y) in the Busan area. Frequency analysis, explanatory factor analysis, confirmatory factor analysis, correlation analysis, and structure model analysis for hypothesis verification were conducted to analyze the data. Based on the results of exploratory factor analysis, five factors were drawn as quality of coffee, indoor environment, service, discount, and brand. Model fidelity and validity was confirmed by implementing the confirmatory factor analysis. In addition, results of structure model analysis confirmed partial relationships among the selection attributes of the college students regarding coffee shops, customer value, and revisit intention. Furthermore, a positive relationship between customer value and revisit intention was also confirmed. Thus, this research suggests that coffee shop managers should manage in a way that customers may acknowledge the value of the expenses they pay.

The purpose of this study is to identify the relationships between satisfaction, behavioral intention and recommended intention of luxury consumers identified in the preceding study as reasons for the explosive growth in the Korean imported car market. Research results found that brand quality, fashion, self-display, and store atmosphere had positive effects on satisfaction, while independent variables influenced behavioral intention. However, it was found that the store atmosphere did not affect satisfaction. Satisfaction expressed a strong positive effect on behavioral intention. In addition, behavioral intention was shown to positively affect recommendation intention. These results imply that consumers are significantly influenced by psychological factors when purchasing imported cars, and that consumers value psychological factors even when resold or recommended to others. The theoretical implications of the study are the empirical analysis of the consumption factors of imported cars using the existing Luxury consumption factors. The practical implications are to provide the importers with a basis for their marketing strategy. Although there are many studies on quality and service in import car markets, there is a lack of research on relevant psychological factors.

The propensity to purchase babies' cosmetics is investigated and analysed for this research. The synopsis of this research paper is as follows. The first, the $68\%$ of all respondents do not how a manufacturer or brand name in the reality of variously emerging domestic and import cosmetics for babies. The second, in case of a child haying a fair, sensitive skin or atopy (atopic dermatitis), the respondents are careful in choosing babies cosmetics but in case of a child having a normal skin the older a child grows from a stage of a new-born, a baby and an infant to a primary-school child, the older its mother is, the more respondents use adults' cosmetics in common rather than use cosmetics only for babies. $7.6\%$ of respondents do not use babies' cosmetirs at ail. Especially, in using bathing goods such as a shampoo or a body cleanser, they frequently use adults' cosmetics in common. The third, the qualify is taken into the utmost consideration in purchasing babies' cosmetics. The Quality of imports is trusted and preferred better than that of domestic goods. The cost of purchasing babies cosmetics is less than 10,000 Won. consumers recognize that the price or cosmetics is rather high. The last, the improvement or babies cosmetics is 'the safety of goods', answered by $56.5\%$ of respondents. The respondents are generally not satisfied with babies' cosmetics. So, a baby's skin is threatened by a newly-built house syndrome, the increase of atopic dermatitis, etc., caused by an environmental pollutions, a change of diet and a change of residential life. Under these actual conditions, babies' cosmetics which can protect a delicate and sensitive skin of a baby should be developed immediately. Consumers should have a correct choice with precise recognition and information on a baby's skin and cosmetics and continually use the efficacious and excellent babies' cosmetics to prevent a baby from a skin irritation, and need to show a keen interest in a healthy skin of a baby.

This study was conducted to investigate the influence of laminaran from Eisenia bicyclis on serum lipid composition of rats fed high fat and cholesterol diets. Fourty male Sprague-Dawley rats weighing $70{\pm}2.5g$ of 4 weeks old were fed experimental diets for 6 weeks with high fat diet consisting of basal diet plus cholesterol (1%) and lard (10%) for the inducement of hyperlipidemia. The effect of laminaran supplements via drinking waters on serum lipid composition of rat were investigated for 5 weeks by administration of experimental diet group fed basal diet only as normal group, control group fed high fat diet, LL group fed high fat diet plus 0.25% laminaran containing water, and LH group fed high fat diet plus 0.5% laminaran containing water, respectively. As a results of experiments, it was found that LL and LH groups showed significant (p<0.05) decrease in body weight gain and liver weight as compared with control and it may caused by decreased FER. The weight of cecum and adipose tissue (EFP) of LL group showed a significantly (p<0.05) decreased patterns compared with control. It was also found that LL and LH diet groups affects the intestinal length and transit time of rat as significantly (p<0.05) increased in length of intestine and decreased in transit time. In addition, LL and LH diet groups showed a dramatic decrease in triglyceride, total and LDL-cholesterol, and significant increase in HDL-cholesterol compared with control diet group, by which results in decreased in AI. These results indicate that crude laminaran from Eisenia bicyclis has a strong hyperlipidemic and hypercholesterolemic activities in rat fed high fat and cholesterol diet.

This study aims to classify the pursuit benefits of smart-phone users, to find smart-phone market segments by pursuit benefits, and to analyze the relative importances of smart-phone attributes according to the smart-phone market segments. As a result, we found that smart-phone users are pursuing the network benefit as well as the two traditional benefits (the utilitarian benefit and the hedonic benefit). According to the levels of these three pursuit benefits, smart-phone users can be classified into four segments : All Benefits Cluster, Utilitarian-Network Benefits Cluster, Hedonic-Network Benefits Cluster, and Non-Network Benefits Cluster. We also verified that, according to the four smart-phone user segments by the pursuit benefits, there exist significant differences in relative importances of the seven smart-phone attributes : hand-set price, hand-set brand, hand-set speed, applications, tariff, mobile internet quality, and number of same service users.

Internet B2C marketplace such as 'Auction', 'G Market', 'Daum onket' etc.(called open market) has grown sharply in sales about yearly 100% rate increase in recent 1-2 years in Korea. Although Open marketplace has much reputation and the customer loyalty, almost of merchants participated in open market, which size in sales are medium/small, has poor reputation and trust. Consumers, who have to get in touch with untrustworthy merchants for trade in openmarket, perceive high trade risk which undergo the monetary damages such as 'merchandise never received'. This examines what factors consumer trust develop in online marketplace. This study explores several perceived risk factors in an open market by factor analysis and multi-regression to prove the relationships between the degree of trust for the merchants and the perceived trade risk. 133 data collected from the open market user data in this survey. In this study, the consumer's trade satisfaction in open market is low by 4.2 point degree of 7 point likert scale. and perceives 4 trade risk factors such as (1) 'failure to honor warranty or guarantee' (2) 'defective/poor goods in quality' (3) 'merchandise never received or received late' (4) 'poor information'. the degree of merchant's trust has significant relationship with the degree of perceived risk(sig. = 0.0000, $R^2=.327$) We find that the open market has to enhance the relationship marketing of trust by developing the strategies.

Marketing channel is recognized as one of the society systems which have the character of functional organization. These organizations are related to each other for specialized and cooperative work. Channel members in distribution channel are striving to accomplish exchange through reciprocal action. Thus channel members exercise their power to take better position in exchange. There will be struggling between members about satisfaction and conflict during this power exercise. Now a days, buyers use more harsh power as large retail firms are increasing. This phenomenon is occurring in the distribution channel. However, there will be different phenomenon in case of agricultural products. Not like industrial product suppliers, agricultural product suppliers have various supply channels and many agricultural products are seasonal. It has also unstable amount supplies. There should be differentiated marketing in agricultural products. Relatively weaker powered suppliers have to strengthen comparative factors and also have to be technically specialized through assessed experience in order to establish strong product sales chain. Making a brand of agricultural product would be also a good idea to increase the product comparability. Channel members need to be recognized their specialized functions in order to make balanced distribution channel. There have to be conversion of concept of relation between suppliers and buyers from subordinate relationship to cooperative relationship.
