Due to the changes in the distribution market, issues related to storage and distribution of agricultural, aquatic and livestock products, and storage and transportation of processed and fresh food are rapidly emerging, and as a result, Cold Chain is naturally receiving attention as one of the logistics services. The purpose of this study is to evaluate the competitiveness of location in the construction of a cold chain cluster centered on the metropolitan area, which has attracted attention in relation to the distribution of cold chains, such as recently refrigerated frozen foods. To this end, this study evaluated the competitiveness of cold chain cluster candidates in the metropolitan area by utilizing the CFPR (Consistent Fuzzy Preference Relations) method that can efficiently extract and quantify expert knowledge. As a result, the location competitiveness was found to be superior to Incheon New Port's hinterland, Gyeonggi South Area (Yongin), Gyeonggi West Area (Gimpo Logistics Complex), and Pyeongtaek Oseong Logistics Complex. In particular, this study extracted the knowledge of refrigerated and refrigerated logistics warehouse operation experts, and conducted detailed competitiveness assessments for cold chain cluster candidates in the metropolitan area, and suggested the optimal cluster candidates. In the future research, it is necessary to classify the questionnaire into the owner, large business group, and public business group, etc., who have the right to purchase and build to secure ownership of the fresh food distribution center.

It is very important that design based on preference of consumers who continuously change. Therefore, the method that can decide on the design concept which a consumer can prefer in future points of time that a design is released is necessary. There may be various ways to decide a design concept, but trend analysis is one of the best ways to be able to satisfy consumer preference. The purpose of this study is to provide a process that can give a direction of MP3 player design oriented consumer emotion. For the purpose, we considered about trend analysis as the ways that can present the design direction that can grasp a change of continuous preference, and a consumer can prefer with early bases in future points of time of a consumer. In this empirical research, we decided on design elements and levels of the elements after collecting 228 MP3 players released from 2000 to 2007, and carried out trend analysis through homogeneity analysis by SPSS program. In the result, we knew that future consumers also will regard emotional experience consumption as important. So, MP3 player design will be developed into consumer emotion-oriented design. We predict 4 trends for a future MP3 player design. 1. Development of high-priced MP3 player with various multimedia functions. 2. Development of MP3 player with basic functions. 3. Development of new convergence products with MP3 function. 4. Development of new MP3 player based on flash memory. If designers can infer a future MP3 player design from this design trend results, the probability that can occupy competitive advantage in their competitions will be high. Therefore this study can be useful.

The anticancer activity of a methanolic extract from lemon leaves (MLL) was assessed in MCF-7-SC human breast cancer stem cells. MLL induced apoptosis in MCF-7-SC, as evidenced by increased apoptotic body formation, sub-G1 cell population, annexin V-positive cells, Bax/Bcl-2 ratio, as well as proteolytic activation of caspase-9 and caspase-3, and degradation of poly (ADP-ribose) polymerase (PARP) protein. Concomitantly, MLL induced the formation of acidic vesicular organelles, increased LC3-II accumulation, and reduced the activation of Akt, mTOR, and p70S6K, suggesting that MLL initiates an autophagic progression in MCF-7-SC via the Akt/mTOR pathway. Epithelial-mesenchymal transition (EMT), a critical step in the acquisition of the metastatic state, is an attractive target for therapeutic interventions directed against tumor metastasis. At low concentrations, MLL induced anti-metastatic effects on MCF-7-SC by inhibiting the EMT process. Exposure to MLL also led to an increase in the epithelial marker E-cadherin, but decreased protein levels of the mesenchymal markers Snail and Slug. Collectively, this study provides evidence that lemon leaves possess cytotoxicity and anti-metastatic properties. Therefore, MLL may prove to be beneficial as a medicinal plant for alternative novel anticancer drugs and nutraceutical products.

With the development and proliferation of three-dimensional(3D) printers, consumers in modern society can now print products of what they want three-dimensionally at home. However, consumers themselves would have to produce digital design maps that are compatible with 3D printers and to set up the optimum printing quality and temperature, as well as to pay for maintenance and repair of 3D printers and to respond to any possible lawsuits related to intellectual property right about designs in order to make possible consumer-tailored manufacturing through 3D printing. However, in reality, since it is very difficult for consumers to respond to these issues, it is necessary to develop services that perform 3D printing on behalf of consumers in the desired direction. Motivated by this objective, this study investigated user experiences on Shapeways(www.shapeways.com), which is a global online 3D printing product and sales companies, from many viewpoints in order to obtain insight into 3D printing services and modes which were preferred by consumers. The study result showed that quantitative evaluations on usability, search process, price adequacy, re-visit intention, diversity of design, and satisfaction of design was scored low overall. Furthermore, this study acquired insight about consumer-tailored 3D printing services through constructive suggestions on multi-language support, openness of manufacturing process, simultaneous operation of online and offline sites, design-oriented consumer-tailored manufacturing service, services that ensure delivery safety and product durability, and surface finishing services. This study is expected to provide a wide range of opinions not only on 3D printing service platform development but also on related industry and research.

The purpose of this study is to suggest the measures to measure the shopping satisfaction and to increase the shopping satisfaction. We conducted surveys and conducted empirical analysis on Chinese tourists visiting duty free shops in Busan using direct survey method. The results of this study are as follows. First, factor analysis for subdividing the duty - free choice attribute was analyzed as store attribute, product attribute, and service attribute. Second, based on this analysis, the effect of each attribute on shopping satisfaction showed statistically significant positive results. Third, the analysis of the relative size of the effects of analytic attributes on satisfaction showed that store attributes were the highest. That is, the quality of duty-free shops, services, and products increases overall shopping satisfaction. Therefore, it can be said that the strategy implementation that improves the quality of the attributes affecting the satisfaction is expected to contribute to the improvement of the management performance, and suggests the management implications for the activation of the operation of the duty - free shop. Future studies will be more meaningful if more variety of shopping places are studied.

This study attempted to secure competitiveness in the cosmetics market and provide basic data needed to promote sales and PR after reflecting consumer demands and needs in the development of cosmeceuticals. For this, it investigated their perception regarding the ingredients and efficacies of cosmeceuticals and repurchase intention among a total of 193 adults in their 20-50s who have had prior experience of buying these types of products from an online shopping mall as the importance of cosmeceuticals is emerging. According to a survey on consumer perceptions regarding the ingredients of cosmeceuticals by gender, there was a clear difference between men and women. In particular, when asked about the ingredients of whitening cosmetics, the percentage of male respondents was as low as 30.8% with a significant difference between men and women (t=31.688,p<0.001). In addition, most consumers were very aware of the efficacies of the ingredients of cosmeceuticals on the skin. In terms of actual repurchase intention, however, a significant difference was found by gender and product type in 3 different cosmeceuticals. In other words, men were lower than women in terms of awareness of cosmeceuticals and repurchase intention. Therefore, the development of a plan which satisfies both men and women, easily labels ingredients and meets consumer needs and demands through proper pricing policy are needed during the development of cosmeceuticals.

Even though the features of the products are almost identical, customers' reactions to each product are quite different depending on the brand image. The purpose of this study is to verify the effects of smart phone's brand images on customer's satisfaction and loyalty and compare the differences between user groups of the Galaxy and iPhone, two representative brands of smart phone. In order to do this, their brand images were classified into functional, symbolic and experiential brand images, and customer's loyalty was also classified into attitudinal and behavioral ones to empirically confirm the influence of those factors. The findings showed that functional and experiential brand images had a positive effect on their level of satisfaction, while symbolic brand images did not have a significant effect on it. Furthermore, it was found that the satisfaction level had a significant effect on attitudinal and behavioral loyalty, and attitudinal loyalty also had a significant effect on behavioral loyalty. Finally, a multiple group analysis of the user groups of Galaxy and iPhone determined that there was a statistically significant difference in the channel between customer satisfaction and attitudinal loyalty.
