We are sometimes interacting with people who we know nothing and facing with the difficult task of making decisions involving risk in social network. To reduce risk, the topic of building Web of trust is receiving considerable attention in social network. The easiest approach to build Web of trust will be to ask users to represent level of trust explicitly toward another users. However, there exists sparsity issue in Web of trust which is represented explicitly by users as well as it is difficult to urge users to express their level of trustworthiness. We propose a fuzzy-based inference model for Web of trust using user behavior information in social network. According to the experiment result which is applied in Epinions.com, the proposed model show improved connectivity in resulting Web of trust as well as reduced prediction error of trustworthiness compared to existing computational model.

The purpose of this study is to examine children's/adolescents' motives for playing internet games and adaptation to school in accordance with their frequency levels of playing internet games. Participants were 236 children from grades 4, 5, and 6 in two elementary schools and 237 adolescents from grades 1, 2, and 3 in one middle school. They were measured on frequency levels of playing internet games, motives for playing internet games, and adaptation to school. Collected data were analyzed by SPSS WIN 12.0 for reliability, frequency, Chi-square test, t-test, Pearson's correlation, and one way ANOVA. Major findings of the research are as follows: First, children's/adolescents' frequency levels of playing internet games differed by their gender. The male ratio was much higher than the female ratio in the potential risk group and the high risk poop. In contrast, no grade differences on the frequency levels of playing internet games were found. Second, children's/adolescents' motives for playing internet games differed by their gender. Especially, among the motives the greatest difference between male and female was marked for 'Social Relationship'. Third, children's/adolescents' motives for playing internet games differed by their frequency levels of playing internet games. For 'Conformity,' the low risk group differed from the high risk group. For 'Spending Time', 'Benefit', 'Competition', and 'Social Relationship', the low risk group differed from the potential risk group and also from the high risk poop. Fourth, children's/adolescents' adaptation to school differed by their frequency levels of playing internet games. The high risk group exhibited a low level of adaptation in 'Academic Activities', 'a subcategory of adaptation to school.

This paper develops a risk index based on an indicator of risk assessment in terms of coastal activity location and accident type. The risk index is derived from a formula which adds the consequence of failure to a vulnerability value, then subtracts the mitigation value. Specifically, the consequence of failure is the number of casualties in coastal activity locations. An indicator of vulnerability refers to coastal environment elements and social elements. A pointer of mitigation includes managerial and organizational elements that indicate the capabilities of coastal activities. A risk rating of coastal activity location is found from a risk matrix consisting of the accident location and type. The purpose of this study is to prevent accidents at coastal activity locations by allowing the Coastal police guard to monitor effectively and inform visitors of potential risks.

The purpose of this study was to investigate the types of perceived risk of Internet shopping and the impact of perceived risk on purchasing behavioral intention of Internet shopping mall shoppers. A self-administrated questionnaire was e-mailed to INR research (www.inr.co.kr) panel who had purchasing experience of fashion product through Internet shopping mall. The perceived risk was reduced when the innovativeness increased and purchasing experience in Internet shopping mall increased. The financial risk had an effect on purchasing intention, and social/psychological risk had impact on revisiting intention and word-of-mouth intention negatively. The performance risk perception had significantly negative influence on word-of-mouth intention. Internet using time per week, purchasing experience and Internet innovativeness were positive impact on purchasing behavioral intention of Internet fashion product.

Purpose - This study aims to illustrate the relationship between demographic factors and perceived risk types, supposing that Korean customers tend to postpone buying or hesitate to purchase the new version of hand sets, because of an early buying risk. Research design, data, and methodology - In addition to existing perceived risk types, the authors introduced an early buying risk. In order to measure each variable, also, the study has employed a five-point Liker-scale. To increase research reliability and validity, the research adopted an exploratory factor analysis, a confirmatory factor analysis, and one-way ANOVA. Results - First, there were statistically significant differences between financial risk and the group. Second, there weren't any statistically significant differences between the group means among the four perceived risk types (Performance Risk, Social Risk, Psychological Risk, and Physical Risk) and 4 factors (Gender, Age, Job, and Education). Lastly, job is apparently differentiated from others (Gender, Age, and Education). Conclusions - The authors found that customers regarded an early buying risk as one of the important perceived risk types, when purchasing a hand set.

This study identifies factors of perceived risk of up-cycling fashion products and investigates perceived risk factors that influence consumers' trust, purchase intention, and recommendation intention towards upcycling fashion products. We also examine the relationship of trust, purchase intention, and recommendation intention for upcycling fashion products. A qualitative research method using a free narrative form and depth interview were used. The perceived risk from up-cycling fashion products generated 5 factor solutions: aesthetic risk, sanitary risk, social risk, performance risk, and economic risk. Next, 201 effective data were collected from a questionnaire survey and analyzed with SPSS 22.0. The results are summarized as follows. First, aesthetic risk and performance risk had a negative effect on products. Second, aesthetic risk and performance risk had negative influence on purchase intention for upcycling fashion products. Third, performance risk had a negative impact on recommendation intention for upcycling fashion products. Fourth, trust had positive effect on purchase intention and recommendation intention for upcycling fashion products. The results of the current study provides various theoretical and practical implications for marketers and retailers interested in up-cycling fashion products.

Elderly people living in poverty are one of the most vulnerable population groups who are at risk of experiencing social exclusion. Social participation is an important contributing factor to active aging and social integration of the older adults living in poverty. This study aims to identify factors affecting social participation of the poor elderly. Data from the second wave of the Korean Longitudinal Study of Ageing was used for the analyses and 1,346 poor elderly aged over 65 were analyzed. The findings showed that age, education, health status, a level of depression, financial stress, and economic activity were associated with the social participation of the elderly living in poverty. These results indicated that psychological empowerment and specific needs of the older adults living in poverty should be considered in developing services and programs to promote social participation of the poor elderly.

The purpose of this study was to investigate tangible clues influence on perceived risk and overall satisfaction of customers at family restaurant in South Korea. In this research overall CFA and SEM were employed to analyze the data. Tangible clues were divided to 3 factors and perceived risk to 6 factors. Tangible clue 1 'physical evidence', had negative(-) influence on financial risk(p<0.01), performance risk(p<0.01) and psychological risk(p<0.001). Tangible clue 2 'employee' affected negatively(-) time risk(p<0.001), performance risk(p<0.001), psychological risk(p<0.01) and social risk(p<0.001). And tangible clue 3 'service process' influenced negatively(-) physical risk(p<0.01), time risk(p<0.05), financial risk (p<0.001) and performance risk(p<0.01). And among customer's perceived risks, 3 factors(time risk~p<0.001, performance risk~p<0.001, social risk~p<0.001) influenced negatively(-) their overall satisfaction. Through these results, it appears that customers perceive various tangible clues and risks at family restaurants. And they are likely to satisfy or dissatisfy according to their perceived risks. As a result, food service companies need to research various customers' perceived risks as important marketing strategy, and reduce them for increase and induction of customers' satisfaction.

The use of construction machinery has been increasing every year due to the large scale, high-rise and lack of workers in construction work. On the other hand, deaths are on the rise every year due to inadequate risk management for construction machinery work. In addition, the number of deaths caused by the lack of signals or insufficient signals during construction machinery work is increasing rapidly, and it is deemed necessary to analyze the actual conditions and take countermeasures. Therefore this study has developed the Strength Risk Index (SRI) based on the Frequency Risk Index (FRI) and the 5W1H by analyzing in-depth deaths caused by construction machinery over the past five years. The risk index (RI) was assessed using the frequency and strength risk index derived to determine whether it is acceptable (acceptable risk < 0.25 ≦ unacceptable risk) and the risk assessment method for reducing risk was proposed by applying 3E (Engineering, Education, Enforcement) measures for each level of risk for unacceptable risk. It also proposed measures to improve the system, such as requirements for signal numbers, mandatory placement standards, and mandatory installation of side and rear monitoring cameras, as measures for accidents caused by failure to deploy signals or insufficient signals, which account for the highest proportion of deaths among construction machinery operators and workers.
