Trust-based solutions provide some form of payment to peers to encourage good behavior. The problem with trust management systems is that they require prior knowledge to work. In other words, peers are vulnerable to attack if they do not have knowledge or correct knowledge of other peers in a trust management system. Therefore, considering only trust is inadequate when a decision is made to identify the best set of peers to utilize. In order to solve the problem, we propose a distributed decision-making mechanism for wireless peer-to-peer (P2P) networks based on game theory and relevant trust mechanisms in which we incorporate the element of trust and risk into a single model. The main idea of our mechanism is to use utility function to express the relationship between benefits and costs of peers, and then make the decision based on expected utility as well as risk attitude in a fully distributed fashion. The unique feature of our mechanism is that it not only helps a peer to select its partners, but also mitigates vulnerabilities in trust-based mechanisms. Through analysis and experiments, we believe our approach is useful for peers to make the decision regarding who to interact with. In addition, it is also a good starting point for exploring tradeoffs among risk, trust and utility.

This study was performed for 235 caddies of 5 membership golf clubs in Jeonnam area to find out their attitude and usage, satisfaction and preference on uniforms $1^{st}\;to\;15^{th}$ February 2007. The result of the study could be summarized as fellows. First, 69.7% of them affirm in the inquiry of 'to feel belong' and 'to tell from others', but they showed low affirmation in other inquiries. In the case of satisfaction of wearing uniforms, they show low satisfaction in most categories such as design, color, materials, activity, and symbol. Second, the most favored color coordination is the two color coordination in the upper and bottom uniform, and the fevered design pattern is the no-pattern one with single color. The favored uniform constitutes a jacket and a trouser in spring through fall, and a parka long enough to hip line, a polo neck, a vest, and a trouser in winter Third, activity is the most important considering factor in the choice of uniform and is also the most improve-wanted factor in the presently wearing uniform. The most important factor in the characteristic of material is absorption of sweat, but there is especially high dissatisfaction in absorption. It shows that there are demands of functional design considering caddies' working environment and activities. Differentiated from other normal uniforms, the uniform should be improved for caddies to develop their specialty and to feel wearing satisfaction.

The demand for water in a city area has enormously increased due to the concentration of population and improvement of the living quality. In this reason, the water shortage and the pollution by city sewage seem to be inevitable. For saving city water and meeting the demands from the city, the wastewater recycling system can be used, which makes used water reusable by a certain purification process. In Korea, the application of a wastewater recycling system to the buildings has continuously been adopted since its first appearance at the Lotte World Complex in 1989. However, the system has not been in fashion because of its high cost and users' negative attitude against recycled water. A research based on literature review and a case study for a recycling water system was carried out and an estimation and evaluation model was proposed. The results from the present study suggest that the optimal size of the recycling water system should be designed within 30-40% of total water demand in a building. Also, it was found that economic benefits could be expected within the payback period of 5.3 years by securing the operation rate over 70%.

This study classified respondents by food-lifestyle and investigated differences in diet-related attitudes and demographic variables among food-lifestyle groups. Diet-related attitudes consisted of variables such as interest in diet, trial number of diet, diet period, weight loss, diet motivation, verification of products approved by the Ministry of Food and Drug Safety, verification of manufacturer's reliability, examination of damage cases and side effects, and awareness of consumer protection law. This study administered a questionnaire survey to adults between the ages of 20 and 39 who lived in Daegu and Uijeongbu from November 17th to December 14th 2014. Data collected from 293 respondents were analyzed using descriptive statistics, factor analyses, cluster analysis, analysis of variance (ANOVA) and chi-square tests. Four clusters (passive eating habit group, active eating habit group, convenience oriented group, and taste and health oriented group) were developed according to four factors of food-lifestyle (health-conscious, popularity-seeking, taste-seeking, convenience-seeking). The results of the ANOVA and chi-square tests indicated significant differences in interest in diet, awareness of consumer protection law, verification of products approved by the Ministry of Food and Drug Safety, verification of manufacturer's reliability, examination of damage cases and side effects, gender, education levels and household monthly income levels among food-lifestyle groups.

This study investigates the importance of brand and retailer associations when consumers evaluate a product category extension in the context of brand and retailer collaborations. Although brand extensions are considered to reduce costs for introducing a new product category, limited study has focused on the role of brand and retailer associations in the context of brand and retailer collaborations. Using a total of 440 participants, a hypothesized model was tested using a structural equation modeling (SEM). The results show that brand and retailer associations influence the perceived fit between a brand and a retailer. In addition, the image fit and quality fit are significantly related to brand and retailer attitudes as well as brand extension evaluation. Since consumers may use their associations with brands or retailers when they perceive product differentiation, market position, and brand extensions, the role of brand or retailer associations is important to marketers, retailers, and consumers. Given the importance of brand and retailer collaborations as a brand positioning strategy in the global branding and retail setting, the findings of this study contribute to brand and retail management by providing empirical evidence on how consumers perceive new products from extended brands in the marketplace when a brand collaborates with a retailer.

This study investigates the impact of heuristic factors on customers' perception of information credibility of influencers on YouTube channels, and the association between customers' perception of information credibility and brand attitude, brand credibility, and purchase intention of cosmetic products in Vietnam. A quantitative approach is employed, with a survey of 270 females who are frequent viewers of beauty content on YouTube channels. The data reliability and validity go through various statistical tests including exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Also, structural equation modeling (SEM) is applied to test the hypotheses. The results reveal that there is a positive association between heuristic factors and the perception of information credibility. This perception of information credibility also influences positively on customers' attitudes toward the brand and brand credibility. Purchase intention is also found to be positively associated with the two latter variables. The study's main findings not only offer advice to practitioners on how to choose the right product endorsers and advertising platforms, but they also offer novel insight from the Vietnamese context that could help to extend the heuristic-systematic model and customers' buy intention behavior.

The current study examined the causal relations among sustainable luxury campaigns' message framing types (negative vs. positive), sustainable brand image and perceived consumer effectiveness. The study tested the moderation of perceived brand luxury about the message framing types, sustainable brand image, and perceived consumer effectiveness. An online survey adopting luxury product is conducted with a total of 194 Korean consumers, testing the hypotheses. In the results, the message framing type is found to significantly affect perceived consumer effectiveness but not sustainable brand image. Perceived brand luxury significantly negatively moderates the relationship between the message framing type and perceived consumer effectiveness but not between the type and sustainable brand image. The results supported the positive influence of perceived consumer effectiveness on sustainable brand image. The moderation of perceived brand luxury was confirmed only for the relationship between the message framing type and perceived consumer effectiveness. The results empirically confirm that the message frame of luxury marketing could positively affect consumers' attitude formation, such as perceived consumer effectiveness, which is consistent with previous studies' research results. The results document that luxury brands using a negative message frame type had a more significant effect on perceived consumer effectiveness than the positive frame type. The findings contribute to the literature of new media-based sustainable marketing of luxury products as to how it affects consumers' brand evaluation and purchase intention, focusing on the causal relationships among the message-framing type of sustainable luxury marketing, sustainable brand image, and perceived consumer effectiveness. Given the increasing pursuit of sustainability in the luxury industry, the results contribute to deriving implications for sustainable marketing of efficient luxury brands.
