This paper analyzes the resistance to mobile commerce services in consumer adoption process. Relative advantage, compatibility, perceived risk, complexity, self-efficacy, innovativeness and attitude for competing service have been chosen as independent variables. This paper also investigates on the significant factors which resist against adoption of mobile commerce service according to adoption phase. The results show that relative advantage, self-efficacy, perceived risk, attitude for competing service are significant factors to affect resistance to mobile commerce services. Relative advantage, perceived risk, attitude for competing service are significant resistance to mobile commerce services for consumers in before-adoption group and compatibility, complexity, self-efficacy are significant factors for consumers in after-adoption group. This study can be extended to new communication services such as Wibro and DMB to reduce resistances in early adoption phase.

Ground shaking recorded during the January 20, 2007, $M_L$ 4.8 Odaesan earthquake (Korea) were used to investigate the role of the crustal structure in producing a strong ground motion, which includes the identification of the phases responsible for the strong ground motion and their implications for seismic hazard assessment. Analyses of strong-motion data together with waveform simulation revealed that critical and post-critical reflections from the crust-mantle boundary are responsible for the abnormal ground motions. This result demonstrates that the crustal structure should be taken into consideration in studies of seismic hazard mitigation even in the areas of relatively low seismicity.

This study was to develope a structural model for risk perception and individual response against terrorism, including several psychological factors - cognitive, social and emotional factors. In this model we measured perceived probability of terrorism, perceived seriousness of the aftermath, and perceived coping(cognitive factors), trust in authorities, in expert group and in preparedness of institutions(social factors), fear and worry(emotional factors), individual preparedness, information seeking, information analysis, and checking relational network(individual behavior responses). Major finding was that cognitive and social factors influenced on emotional factors and then emotional factors influenced on the individual responses. The perceived coping, which one of cognitive factors was linked with individual responses directly and indirectly via emotion factors. We discussed the importance of perceived coping in preparing for terrorism.

Smart clothing represents the future of both the textile/clothing industry and electronic industry and has an effort to make electronic devices a genuine part of our daily life. The researches about technologies innovation and application of smart clothing can be found in previous studies. But consumer researches about perception or attitude toward smart clothing can be hardly found. Therefore, we proposed a conceptual framework that explores the impact of perceived risks on perceived attributes to adopt smart clothing. In addition, we compared differences of this framework among three counties. Korea, U.S. and Spain. Based on the literature review and hypotheses development, a research model was constructed. After data analysis using Amos 7.0, the results can be concluded as following: First, the influences of psychological risk among Korea, U.S. and Spain are same. Psychological risk has negative effect on relative advantage and complexity, but has positive effect on trialability. Second, loss risk was found to have nothing to do with relative advantage. But it negatively influences complexity for Korean consumers and positively influences trialability for both Korean and American consumers. Third, the influences of performance risk for different consumers are different. At last, based on our discussion, some implications were also concluded.

This study focuses on the margin of human error when a navigator is embarrassed by the psychological fear of collision in a close-quarter situation (CQS) and is unable to perform as per the prescribed collision avoidance measures. The purpose of the study is to identify the effects of the navigator's personal characteristics or factors in relation to on-board career (OC), license rating (LR), and age on the perceived collision risk (PCR) in CQSs. In order to obtain quantified data regarding the collision risk perceived by the navigator in four typical CQSs between their own ship and a target ship, this study measured and collated the heart rate variability of 30 navigators on their own ship when two ships approached each other at a speed of 10 knots from 2.5 nautical miles to a collision situation. According to a multiple regression analysis of the measured values, the navigators' OC and LR factors had negative effects on the PCR, while the age factor had no significant effect on PCR. The t-test results showed that the PCR value was significantly higher for navigators with an OC ≤ 4 years than for those with an OC ≥ 5 years, and the LR factor was significantly higher for a class 4~6 group than for a class 2~3. This finding may be applied to the development of collision risk warning systems, particularly for navigators.

Using two large coast guard ships at sea, we created four encounter situations ($000^{\circ}$, $045^{\circ}$, $090^{\circ}$, $135^{\circ}$) with high possibility of collision, from 3 NM up to 0.25 NM. As relative distance was gradually decreased, the subjects were measured at 0.25 NM intervals and perceived ship collision risk (PSCR) was determined by looking at the opponent ship. Characteristics were statistically analyzed using the obtained data. The purpose of this study was to analyze the characteristics of collision risk values obtained from twelve intervals, from 3 NM to 0.25 NM relative to encounter situations by curve fitting with appropriate polynomials, to determine the distance from which the change in perceived collision risk is greatest. As a result, an optimal regression equation for each distance interval was derived from each analysis direction. The greatest variation in average collision risk value was over the range 1.25 ~ 1 NM, and the collision risk value was largest at 1 NM. The maximum change in perceived collision risk was at 1 NM. These results can contribute to preventive guidelines to minimize human error in close proximity situations with a high probability of ship collision.

This study examined the influences of product knowledge(subject knowledge, purchase experience and information search) on perceived risks and benefits to natural dyeing product. Data were collected from a total of 213 Korean females ranging from 20 to 50 years old who know natural dyeing product through online survey. There were significant differences between(or among) groups with different levels of subject knowledge, purchase experience and information search in several types of perceived risks and benefits to natural dyeing product. Consumers with high knowledge of natural dyeing product perceived several types of risks lower than consumers with low knowledge but they perceived several types of benefits higher than consumers with low knowledge.

The purpose of this study was to investigate the differences among internet and TV home-shopping perceived risk segments in regard to clothing shopping orientations and purchase intention. The subjects used for the study were 290 female consumers aged from 20 to 40 living in Seoul. The study used factor analysis, cluster analysis, ANOVA, Duncan test, and $\chi^2-test$. The results showed that the Internet and TV home-shopping perceived risks consisted of 9 factors: Products uncertainty risk, Internet shopping mall trust risk, account-related risk, delivery risk, social risk, size risk, exchange/return risk, TV watching-related risk, and price risk. The cluster analysis showed that there were five groups segmented: Size risk/TV watching risk group, Social risk/Internet trust risk group, Return risk/TV watching low-risk group, Delivery risk/product trust group, and Product risk group. The clothing shopping orientations were classified by 5 factors: Planned shopping, pleasure shopping, sales/fashion oriented shopping, time saving shopping, and credit card preference/in-store oriented shopping. The results showed that the five segmented perceived risk groups differed in regard to clothing shopping orientations, purchase intention, and demographics. Further group differences and implications of the results were discussed.

The purpose of this study is to analyze consumers' perceived risk which is shown in the process of purchase phase and consumption phase for the counterfeits of fashion luxury brands and to analyze the interrelationship of each type of perceived risk. The research method of the study used a qualitative approach. 6 informants were selected and then an in-depth interview was held with them. Through this process the data on the perceived risk for counterfeits were collected and analyzed. The results of the study are as follows; The perceived level of psychological risk including counterfeits exposure was extremely high; besides, economic risk and performance risk were also perceived. On the contrary, the perceived level of social risk and fashionability loss were relatively low. The risk perception for counterfeits appeared not only on the purchase phase but also on the consumption phase, and when perceived risk existed on the consumption phase, it had an influence on the level of perceived risk on the next purchase phase. However the psychological risk was continuously perceived on both purchase and consumption phase, even if it did not exist on the consumption phase. Psychological risk, economic risk and performance risk were not independent but interdependent. Moreover, the entire level of perceived risk could be controlled by reducing the level of other perceived risks when a certain type of risk was highly perceived.

This study focuses on how positive emotions form when consumers impulsively purchase fashion products. Examined are the novelty seeking situations and the fashion knowledge of consumers as influential factors that affect positive impulsive shopping emotions along with the mediating role of the perceived risk of consumers for purchase and non-purchase. An online survey was conducted for the empirical research with a questionnaire about the fashion impulsive purchases of a product within the last 2 months. A total of 555 surveys were collected from impulsive female buyers and 404 complete responses were analyzed. The results find that the perceived risk is identified into purchase and non-purchase perspectives. Purchase perceived risk influenced negatively on positive emotions of impulsive purchase and non-purchase perceived risk positively. The perceived risk for non-purchase versus purchase increased by the more fashion knowledge consumers had and the more they shopped as novelty seeking. The results imply that non-purchase perceived risk importantly mediated between the influential factors and positive affect for impulsive purchase. Based on the findings, this study proposed some marketing suggestions and thoughts about effective purchase stimulation.
