New elderly consumer market composed of consumers 50 years or older has both resemblance and difference with younger fashion market. This study aimed to examine the effect of socio-demographic and psychological factors on fashion innovativeness and monthly spending on clothing of new aged elderly consumers with the moderating role of materialism. The study found that socio-demographic factors tended to have direct effects on clothing spending, while psychographic factors have both direct effect and indirect effect through fashion innovativeness. The mediating role of fashion innovativeness in predicting clothing spending was found to be moderated by materialism of new elderly consumers. Marketing implications and limitations were discussed.

In recent years, IPTV attracts great attention along with the digital convergence of communication and media technologies. IPTV combines the advantages of TV and Internet and changes our lifestyle dramatically. In addition, the IPTV service is capable of becoming a new business model which has huge growth potentials in technology-converging marketplaces. This study examines critical factors on the consumer's adoption of the IPTV service. Based on the Innovation Diffusion Theory (IDT), IPTV specific attributes and personal characteristics, we derive eight key factors in the research model. compatibility, ease of use, image, diversity of contents, interactivity, monetary value, social influence, and user satisfaction. Using the partial least square (PLS) method on the data collected through a web-based survey, we test our research model with several hypotheses. From this study, we find that diversity of contents, compatibility and interactivity have a significant indirect effect on the use of IPTV service via user satisfaction, and user satisfaction and social influence also have a significant direct impact on the IPTV use. These findings not only provide practical insights on the consumer acceptance of new technology-converging services, but also help managers to plan their marketing strategies better.

This paper proposes Direct Load Control(DLC) operation scheme using a bidding system and the methodology to value proper quantity decided by the DLC program, which is a kind of resources for stabilization of electricity market price during peak times by managing consumer electricity demand. Since DLC program in Korea is based on the contract with the customers participating in this program, it is difficult to anticipate voluntary participation. That is, incentive for participants in DLC program is insufficient. To cope with this point, it is necessary to develop a new market mechanism and market compatible operation scheme for DLC programs. DLC market mechanism is deemed to be equipped with iterative bidding system, independent operation from energy market, and interactive with bidding information on energy market. With this market mechanism, it is important to find the optimal operation point of DLC allowing for the factors of stabilizing the electricity market price and compensating DLC implementation. This paper focuses on the mathematical approaches for the bid-based DLC operation scheme and examines several scenarios for the following technical justifications: 1) stabilization of electricity market price during peak times, 2) elasticity of demand.

This paper proposes a value-based pricing suitable for deregulation situation in electricity market, where the value is measured based on the service quality such as system reliability. The proposed approach makes it possible to maximize social welfare, in that diversified service can produce the optimal combination set of demand and supply. The proposed pricing can also be applied to a direct load control.

Because of the burgeoning demand of the energy, the countries are finding sustainable solutions for these emerging challenges. Demand Side Management is playing a significant role in managing the demand with an aim to support the electrical grid during the peak hours. However, advancement in controls and communication technologies, the aggregators are appearing as a third party entity in implementing demand response program. In this paper, a detailed mathematical framework is discussed in which the aggregator acts as an energy service provider between the utility and the consumers, and facilitate the consumers to actively participate in demand side management by introducing the new concept of demand reduction bidding (DRB) under constrained direct load control. Paper also presented an algorithm for the proposed framework and demonstrated the efficacy of the algorithm by considering few case studies and concluded with simulation results and discussions.

The purpose of this study was to examine how congruity between self-image and store image affects a customer's satisfaction with the retailer, loyalty towards that retailer, and patronage behavior toward that retailer in a fashion retailing context. In addition to the direct effects of selfcongruity on consumer responses, the mediating roles of satisfaction and retailer loyalty were also examined. A convenience sample of 137 college students participated in an online survey. Path analysis showed that self-congruity had a direct effect on satisfaction, but not on retailer loyalty and patronage behavior. However, the effect of self-congruity on retailer loyalty and patronage behavior was fully mediated by satisfaction. Satisfaction had a positive effect on both retailer loyalty and patronage behavior. The effect of satisfaction on patronage behavior was partially mediated by retailer loyalty. As supported in the study, self-congruity can induce retailer loyalty. Given that retailers have direct control over developing a certain store image that affects perceptions of self-congruity of their target market, the findings of the study provide useful information for fashion retailers. The findings of the study add to current selfcongruity literature by extending to fashion retailing and also by examining the mediating roles of satisfaction and retailer loyalty on the effects of self-congruity.

The purpose of this study is to investigate the effect of voluntary purchasing motives on insurance consumer satisfaction. The purpose of this study is to investigate the direct and indirect effects of insurance consumption satisfaction including psychological needs of consumers that induce voluntary purchase motivation based on psychological self-determinism theory. The research hypotheses and models were verified through structural equation analysis using online surveys of 1,225 insurance consumers. As a result of the study, the satisfaction of insurance consumption is increased when purchasing by voluntary purchase motive, in which consumers perceive the necessity of purchasing themselves. The positive perception of insurance consumption autonomy and insurance consumption environment increases the motivation to purchase voluntarily, Respectively. Through this study, it is suggested that excessive marketing of insurance companies and self-confidence of insurance consumers may hinder insurance consumption satisfaction and education of consumption attitudes of financial consumers to raise awareness of autonomous rights and responsibilities of insurance consumers.

Consumers who purchase products from foreign countries and deliver them back to Korea are increasing. According to the Korea Fashion & Textile News (2015), overseas direct shopping reported 39% increase compared to 2013. Furthermore, clothes accounted for 19% of product category. Therefore, the service quality of overseas purchase sites is becoming more important, but studies have been limited. this research focuses on investigating the effects of consumers' shopping orientation on service quality and the effects of service quality on trust, satisfaction, and consumer loyalty. The survey was administered to consumers who had experiences in purchasing through overseas direct purchase websites. The results showed that the perception of service quality differed depending on the respondent's shopping orientation. Among the four shopping orientation groups(shopping confidence, shopping enjoyment, trend pursuit, and shopping follower groups), the shopping confidence group showed the highest mean for all service quality factors. All the groups showed the highest scores on product and trust among the factors of service quality. Next, the results revealed that service quality positively influenced consumers' trust on websites that provide overseas direct purchase services, which further improved customer loyalty. Therefore, the study gives managerial suggestions to online retailers that provide oversea shopping service. They need to provide higher site efficiency, security, product reliability, and responsiveness to cultivate international customers' trust and satisfaction. In particular, it will be important for them to offer accurate, reliable product information and various languages for overseas customers.

Hydrogen, which can be produced from abundant and widely distributed renewable energy resources, seems to be a promising candidate for solving the concerns for improving energy security, urban air pollution, and reducing greenhouse gas emissions. The two primary motivating factors for hydrogen economy are fossil fuel supply limitations and concerns about global warming. But the safety issues associated with hydrogen economy need to be investigated and fully understood before being considered as a future energy source. Limited operating experience with hydrogen energy systems in consumer environments is recognised as a significant barrier to the implementation of hydrogen economy. To prevent unnecessary restrictions on emerging codes, standards and local regulations, safety policies based on real hazards should be developed. This article studies briefly the direct impact-distances from hazard events such as hydrogen release and jet fire, and damage levels from hydrogen gas explosion in a confined space. Based on the direct impact-distances indicated in the accident scenarios and consumer environments in Korea, the safety policies, which are related to hydrogen filling station, hydrogen fuel cell car, portable fuel cell, domestic fuel cells, and hydrogen town, are suggested to implement hydrogen economy. To apply the safety policies and overcome the disadvantages of prescriptive risk management, which is setting guidance in great detail to management well known risk but is not covering unidentified risk, hybrid risk management model is also proposed.
