Mobile shopping, through the use of the smart phone, has become a very popular shopping method for consumers due to it not being limited by time or place. This research aims do the following:1)find the causes for consumers shifting to mobile shopping with the focus on fashion and beauty items; and in order to so, this research will use the TAM that was found by David et al (1989), and 2) distinguish any behavioral differences between consumer groups divided into purchasing intention of fashion and beauty items through smart phone. Path analysis was performed to verify the cause-and-effect relationship between the variables. Personal characteristics(i.e. market maven, time orientation), perceived usability, ease of use, attitude towards mobile shopping, and purchase intentions were all treated as dependant variables. The results showed that attitude towards mobile shopping was the most important variable on mobile shopping intentions. Time-oriented and Market Maven were thought to affect mobile shopping attitude and the dependent variables of purchase intention. Also, when purchasing smart phones, consumers highly valued smart phone's popularity; people with higher purchasing intention mainly used entertainment and utility apps. The following are the main reasons for not purchasing through mobile shopping: they are slower than computers, inconveniences in viewing due to small size of the screen, and security issues. The consumers used the internet as their main source of acquiring daily information. In this research, factors that affect the purchase intention were studied. However, it is difficult to firmly insist that this research correctly predicts the actual purchase intention-further studies need to be done to investigate the relationship between mobile purchase intention and actual purchase intention.

In terms of years of life lost to premature mortality, cancer imposes the highest burden in Korea. In order to reduce the burden of cancer, the Korean government has implemented cancer control programs aiming to reduce cancer incidence, to increase survival rates, and to decrease cancer mortality. However, these programs may paradoxically increase the cost burden. For examples, a cancer screening program for early detection could bring about over-diagnosis and over-treatment, and supplying medical services in a paternalistic manner could lead to defensive medicine or futile care. As a practical measure to reduce the cost burden of cancer, appropriate cancer care should be established. Ensuring appropriateness requires patient-doctor communication to ensure that utility values are shared and that autonomous decisions are made regarding medical services. Thus, strategies for reducing the cost burden of cancer through ensuring appropriate patient-centered care include introducing value-based medicine, conducting cost-utility studies, and developing patient decision aids.

This paper analyzes a robust optimal reinsurance and investment strategy for an Ambiguity-Averse Insurer (AAI), who worries about model misspecification and insists on seeking robust optimal strategies. The AAI's surplus process is assumed to follow a jump-diffusion model, and he is allowed to purchase proportional reinsurance or acquire new business, meanwhile invest his surplus in a risk-free asset and a risky-asset, whose price is described by an Ornstein-Uhlenbeck process. Under the criterion for maximizing the expected exponential utility of terminal wealth, robust optimal strategy and value function are derived by applying the stochastic dynamic programming approach. Serval numerical examples are given to illustrate the impact of model parameters on the robust optimal strategies and the loss utility function from ignoring the model uncertainty.

The purpose of this study was to investigate the present state of e-business according to the establishment year and the sales approach of Dongdaemun clothing market and to present problems according to e-business activation of it and its developmental direction. The subjects for this study were selected out of Dongdaemun clothing markets being considered as more fashion-oriented markets and were divided into two categories both according to the establishment year and according to the sales approach. As a result, Dongdaemun clothing markets are mainly divided into traditional wholesale market, eastern wholesale & retail market, and western retail market and having dealings with each other according to the market's characteristics. The utility percentage of on-line e-business according to the establishment year and the sales approach showed that traditional wholesale market was 42%, eastern wholesale & retail market 0.75%, and western retail market 11%. This result indicated that the utility percentage of traditional wholesale market showed much higher than eastern wholesale & retail market and western retail market. This would be because the structural characteristics of clothing market delayed the utility of e-business. For the problems on the utility of on-line e-business through counselling, traditional wholesale market showed much higher than wholesale & retail market and retail market because it had little problems on design imitation in retail market due to export by order and mass production. The problems of low utility of on-line e-business in Dongdaemun clothing market would result from well-timed on-line update according to rapid goods cycle, constant satisfaction for additional order, standardization of size and quality, and inexpensive internet purchase despite of express expense.

This study aims at understanding gender difference in trust and the related factors affecting the intention to purchase voice speakers VS. VS are one of the innovations that are emerging at a fast pace in the market. Although it seems to be widely embraced by both genders, people do not intend to use them in some cases due to a lack of trust and the rumors circling these types of technologies. Nevertheless, there are particular barriers to the acceptance of VS technology between females and males due to unfamiliarity with the effective components of such technologies. Therefore, assuming that increasing the knowledge-based familiarity with an effective technique is essential for accepting it. So far, only little is known about VS and its concepts to increase the familiarity and, as a consequence, the acceptance of effective technology. Technology adoption in gender has been studied for many years, and there are many general models in the literature describing it. However, having more customized models for emerging technologies upon their features seems necessary. This study is based on Theory of Reasoned Action and trust-based acceptance which provides a background for understanding the relationships between beliefs, attitude, intentions, and subject norms and how it's affecting gender trust in VS. The statistical analysis results indicate that perceived system quality and perceived interaction quality have stronger influences on trust for males, while privacy concern and emotional trust have stronger influences on trust for females with the intention of purchase for both genders. Our study can be beneficial for future research in the areas of Perceived risk and Perceived utility and behavioral intention to use and human-technology interaction and psychology.

Lots of networks are constructed in a large scale industrial complex. Each network meet their demands through production or transportation of materials which are needed to companies in a network. Network directly produces materials for satisfying demands in a company or purchase form outside due to demand uncertainty, financial factor, and so on. Especially utility network and hydrogen network are typical and major networks in a large scale industrial complex. Many studies have been done mainly with focusing on minimizing the total cost or optimizing the network structure. But, few research tries to make an integrated network model by connecting utility network and hydrogen network In this study, deterministic mixed integer linear programming model is developed for integrating utility network and hydrogen network. Steam Methane Reforming process is necessary for combining two networks. After producing hydrogen from Steam-Methane Reforming process whose raw material is steam vents from utility network, produced hydrogen go into hydrogen network and fulfill own needs. Proposed model can suggest optimized case in integrated network model, optimized blueprint, and calculate optimal total cost. The capability of the proposed model is tested by applying it to Yeosu industrial complex in Korea. Yeosu industrial complex has the one of the biggest petrochemical complex and various papers are based in data of Yeosu industrial complex. From a case study, the integrated network model suggests more optimal conclusions compared with previous results obtained by individually researching utility network and hydrogen network.

The purpose of this study was to examine the sportswear purchase decision factors and brand preference of college students. The subjects in this study were 614 college students who were selected by cluster random sampling from Daegu and North Gyeongsang Province. The collected data were analyzed by crosstab analysis, and the findings of the study were as follows: If a sportswear company has college students as a target market, first, the company needs to consider design and utility. Second, the company needs to expand internet sale while maintaining a strategy for centering on speciality shop and department store as for a sale of sportswear. Third, the college students themselves have a right of choice according to purchasing sportswear. Thus, a distribution company requires a direct marketing strategy targeting college students. Fourth, simple design of adding a fashion trend is needed. Fifth, the sportswear company needs to expand production and sale in jumpers and trousers based on T-shirts. Sixth, color in sportswear needs to be composed of design based on gray or black color. In order for a sportswear company to be adjusted to the global market environment here after, it requires an effort to continuously grasp consumers' trend and to apply new design and color. Also, the company will be able to be equipped with competitive edge by producing diversely functional products that are demanded by the segmented market.
