본 연구는 제품의 가격에 부과가 되어 있는 부가가치세(Value Added Tax)를 어떻게 표시(VAT 프레임: VAT포함, VAT별도)하느냐에 따라 소비자들의 가격제시방법에 대한 태도가 달라질 수 있음을 살펴보았다. 또한 사고방식(종합적 vs. 분석적)에 따른 태도변화 즉, 조절효과도 살펴보았다. 이를 위해 실험자극물을 4가지 형태[(제품: 실용/쾌락)${\times}$(VAT: 포함/별도)]로 조작하였다. 1) 조사대상자들은 VAT별도 가격제시 방법보다 VAT포함 가격제시 방법을 더 선호하는 것으로 나타났다. 2) 사고방식의 조절효과도 확인되었다. 즉 분석적 사고자의 경우에는 전자와 후자 간에 유의미한 차이가 없는 것으로 나타났으며, 종합적 사고자의 경우에는 전자보다 후자를 더 선호하는 것으로 나타났다. 기업의 마케팅 실무 담당자들은 이와 같은 연구결과를 고려하여 효과적인 마케팅 전략을 수립하는데 도움을 받을 수 있을 것으로 기대된다.

The purposes of this study were to investigate the social instrumentality of appearance, appearance orientation, and cosmetics purchasing behaviors of Chinese male consumers, and to find differences in the cosmetics purchasing behaviors of the male consumer groups, which were segmented by the social instrumentality of appearance and appearance orientation. The subjects were 400 adult males in their 20s to 30s from Gillim province in China. The measurements consisted of the social instrumentality of appearance, appearance orientation, cosmetics purchasing behavior, and the subject' demographic attributes. The data was analyzed by descriptive statistics, frequency analysis, $x^2$ test, multiple response analysis, cluster analysis, ANOVA, and Duncan's multiple range test, using SPSS program. The results were as follows. First, young Chinese male consumers had a high sense of the social instrumentality of appearance, but the tendency to invest time and effort to enhance their looks was still low. Second, on the basis of the social instrumentality of appearance and appearance orientation, young Chinese male consumers were classified into four groups (high involvement group, instrumentality group, orientation group, and low involvement group). Third, the four male consumer groups revealed many significant differences in various cosmetic purchasing behaviors (purchasing items, information sources, product selection criteria, purchasing motives, purchasing locations, store selection criteria, purchasing price, purchasing frequency, and cosmetics improvements). Therefore, the social instrumentality of appearance and appearance orientation are seen as significant variables to effectively segment the Chinese male consumer market. The cosmetics companies targeting young Chinese men need to establish differentiated marketing strategies, considering the characteristics of each segment of the consumer market.

Succinic acid, a representative biomass-derived platform chemical, is a major fermentation product of Actinobacillus succinogenes. It is well known that carbon dioxide is consumed during the succinate fermentation, but the biochemical mechanism behind this phenomenon is not yet understood well. In this study, it was found that the addition of carbonic anhydrase (CA)s into media significantly enhances the succinic acid production by A. succinogenes during the fermentation supplied with carbon dioxide. It is likely that the (bi) carbonate produced by the CA activity from gaseous carbon dioxide is favoured by A. succinogenes for consumption and utilization. Therefore, the $MgCO_3$ requirement could be significantly reduced without compromising the succinate productivity. Furthermore, because of too high price of the commercial carbonic anhydrase, it was undertaken to economically overproduce a cyanobacterial carbonic anhydrase by the use of a recombinant Pichia pastoris. An expression vector system was constructed with the carbonic anhydrase gene PCR-cloned from Cyanobacterium Synechocystis sp., and introduced into P. pastoris for fermentation studies. About 95.9 g/L of succinic acid was produced in the production medium with 30 ppm of carbonic anhydrase, approximately 2 fold higher productivity compared to the parallel process with no supplementation of the enzyme. It is expected that this method can provide a valuable way of overcoming inefficiencies inherent in gas supply during $CO_2$-based bioprocesses like succinic acid fermentation.

우리나라는 농산물 수출확대를 위하여 농산물 수출지원제도를 운영하고 있으며 수출물류비지원사업도 여기에 포함되어 있다. 수출물류비지원을 통한 수출지원사업을 통해 농산물의 수출확대는 농업부문의 수출산업화는 물론 신수요 창출과 국내 농산물 가격의 안정화에도 기여한다. 우리나라가 DDA 협상에서 개도국지위를 유지하게 되면 WTO 규정이 허용하는 범위 내에서 수출보조의 지속적인 지원이 일정기간까지 가능하나 개도국지위를 상실하게 되면 수출보조금으로 지원하는 수출물류비 등 각종의 지원이 향후 협상에서 결정되는 특정연도에는 완전폐지를 해야 하는 상황이다. 따라서 본 연구에서는 농산물에 대한 수출물류비 지원이 수출에 미치는 효과를 분석하고, WTO/DDA 농업협상 결과 예상되는 수출물류비 감축이나 철폐에 대비하기 위한 농산물 수출물류활동의 활성화 방안과 과제에 대하여 연구해보고자 한다.

Purpose Since the Bitcoin, which was the first virtual currency, was made at 2009, almost 1,000 virtual currencies appeared onstage in the world. Even though virtual currencies have the function of money as a medium of exchange or contract, any of those has not yet entered the commercialization stage. Instead, some of the virtual currencies show the nature of investment assets. In the case of virtual money investment, users tend to use all the information of the world because information transfer is very easy and capital movement is almost free between different countries. In addition, as the transaction sizes of virtual currencies increase, a virtual currency price is no longer independent and is likely to be affected by the prices of other virtual currencies. Therefore, it is necessary to understand the influence among virtual currency markets, which helps successful implementation of investment strategies. Design/methodology/approach This study focuses on the investment product function of virtual money and conducts the analysis using the time series model used in the financial and economic areas. In this paper, we try to analyze the return and volatility transfer effect of virtual money markets through GJR-GARCH model. Findings This study is expected to find out whether we can make market forecasts through reflecting changes in other markets. In addition, we can reduce the trial and error of user decision making by using the information on the yield and volatility transition effect derived from the research results, and it is expected to reduce the opportunity cost of users.

Fur clothing as fashion items is expanding into casual & ladies's wear market as well as fur market. The interest of fur fashion is rising. So this study compares and analyzes the merchandising process of textile clothing also it of fur clothing by merchandising steps. Fur clothing has so many change factors at time of purchase by scarcity of raw material, price fluctuation, exchange rate and others. Therefore it is primarily about securing of raw material. As soon as plan of product is finished, the purchase of fur raw material has to be started while progress of design products for commercializing the fur clothing. The design of fur clothing is consist of material design, color design and shape design. And It makes a new trend & market as we are developing new & various treatments. The some of imported materials are transferred to the factory for being treated first dressing, fabric treatments and dyeing processing according to the design. The first treated materials are transferred to the sewing factory again for secondary treatments and finally inspected and shipped. During secondary treatments the fur has gone through various manufacturing process for using like fabric materials and it takes long time because almost work is running manually. Unlike fabric clothing, fur clothing's manufacturing method is complicated and various from material process to shape process as per feature. Therefore the merchandising with fur cannot make mass production also needs detail craftsmanship depending by expert's skills. On this wise the fur clothing takes long time to the completion thus it has been risky and costly.

The purpose of this study is to investigate the user characteristics in different age groups by investigating the level of satisfaction and preference of design and function of mobile phone. 160 subjects participated in the experiment. Subjects with different ages were selected and divided into four groups: young age group (20 to less than 45), $1^{st}$ middle age group (45 to less than 55), $2^{nd}$ middle age group(55 to less than 65), and elderly group(over 65). A questionnaire was developed based on the previous design guideline, and additional questions were made to test newly developed function and design of the mobile phone. In particular, depth interviews were conducted in order to have a proper response from old subjects who have difficulties in completing written questionnaire. In result, it was found that except for price the major criterion to purchase mobile phone was the design, and the function of phone was the next except for elderly group. In the case of elderly group, the screen size is the first. Statistical results indicated that 37.5% of the young age group, 22.5% of $1^{st}$ middle age group, 22.5% of $2^{nd}$ middle age group and 10.0% of the elderly group preferred the design to function when they purchase mobile phones. Most elderly people were not satisfied with the supplementary function of the mobile phone. The $1^{st}$ middle age group did not know exactly how to use the supplementary service although they were willing to use it. Regarding the emotional preference on the type of phone, the sliding type was preferred most. Current results can be used to anticipate the future trend of mobile phone and design a user-friendly product for the aged population.

The usage of wild ginseng (Panax ginseng C.A. Meyer) has been limited due to short supply and high price. Therefore, sufficient production as well as efficient extraction of mountain ginseng are required for the development as products. In this study, wild ginseng adventitious root cultures were prepared for efficient production with advantages of fast growth and stable production. Treatment of methyl jasmonate (MJ) to wild ginseng adventitious root cultures increased the extraction yield and antioxidative activity. Further investigation on effect of extraction conditions suggested the importance of ethanol concentration on antioxidative activity and extraction yield of MJ-treated wild ginseng adventitious root cultures. Optimized extraction condition of MJ-treated wild ginseng adventitious root cultures for maximum extraction yield and antioxidative activity was determined using response surface methodology with three-level-three-factor Box-Behnken design (BBD). Extraction of 1 g MJ-treated wild ginseng adventitious root culture with 30 ml of 9% ethanol at $30^{\circ}C$ produced 310.2 mg extract with 71.0% antioxidative activity at $100{\mu}g/ml$. Taken together, MJ-treated wild ginseng adventitious root culture is valuable source for wild ginseng usage and optimized extraction condition can be used for the development of functional products or folk remedies.
