By using text mining, we explore the factors responsible for an increase in SUV preference. We collected 32,679 posts related to SUVs from "Bobaedream," the largest online automobile community in South Korea, and applied the LDA topic model. While previous studies have explained the SUV boom as an individual's risk aversion strategy from crime, the result shows that the topic of 'Safety' appears to be an important factor in the SUV discourse in the context of a car accident and high-speed driving situation. To conclude, the consumption of SUVs in Korean society serves as a mean to prevent anxiety and danger to individuals when driving. We insist that decreasing social trust, caused by an increase in inequality, underlies the perception of risk on the road.

As the importance of software in various industry areas has been increased, the number of accidents related to software safety are growing up. The key industries such as railroads, aviation and medicine, recommend IEC 61508 and international safety standards for their own to achieve functional safety and reduce the issues caused by that. For equipment of ship navigation, there are not any particular standards or guidance which Korean users can introduce as considering software functional safety. This article defines the procedure and outcomes of the risk analysis in order to secure software functional safety in marine navigational equipment and applies them to an echo sounder as a case study.

The purpose of this study was to investigate the factors related to problem drinking in male workers according to occupational classes. Data were derived from the 2012 Korean National Survey on male workers. A total of 391 office workers, 707 manufacturing workers, and 309 service workers participated in this study. Data were analyzed using Rao-Scott $X^2$-test, simple and multiple logistic regressions. Problem drinking was defined as ${\geq}8$ points in the Alcohol Use Disorders Identification Test. The problem drinking rates were 45.1% in office workers, 39.1% in manufacturing, and 42.3% in service. In office workers, the factor related to problem drinking was only smoking. In manufacturing workers, the factors related to problem drinking were spouse, smoking and prevalence of Diabetes. In service workers, the factors related to problem drinking were age and smoking. Therefore, different intervention should be developed for each occupational class in order to manage the problem drinking in male workers.

According to the accident statistics of 2006, it can be recognized that drivers' characteristics and driving behaviors are the most causational factors on the traffic accidents. At present, many recording tools such as digital speedometer or black box are distributed in the market to meet social requests of decreasing traffic accidents and increasing safe driving behaviors. However, it is also true that the system preventing any possible vehicle accidents in advance has not been developed. In this study, we developed critical value for deciding dangerous driving behaviors. The developed critical value could be used to contribute to safety driving management systematization and safety driving behaviors.

This study examined the relationships among perceived values(environmental value, functional value), perceived risk, subjective norm, pro-social behavior, product attitude, and usage intention related to car-sharing service. The study also explored the moderating role of possessive desire between the antecedent variables and consumer attitude. 238 survey responses of Chinese consumers were analyzed by structural equation modeling. It is indicated that environmental value, functional value, subjective norm, pro-social behavior had positive effects on attitude, thereby affecting the usage intention of this service. Possessive desire moderated the relationship between environmental value, subjective norm and attitude. These results are expected to provide various marketing strategies for sharing economy services.

With widespread use of information technologies, information privacy issues have been gaining more attention by not only the public but also researchers. The number of studies on the issues has been increasing exponentially, which makes incomprehensible the whole picture of research outcome. Thus, it is necessary to conduct a systematic examination of past research. This study developed two competing models with four essential constructs in information privacy research and empirically tested the models with data obtained from previous studies. This study employed a quantitative meta-analysis method called TSSEM. It is one of MASEM methods in which structural equation modeling and meta-analysis are integrated. The analysis results indicated that risk-centric model exhibited much better model fits than those of concern-centric model. This study implies that traditional concern-centric model should be questioned it's explanatory power of the model and researchers may consider alternative risk-centric model to explain user's intention to provide privacy information.

This study was intended to analyze the effects of Entrepreneurship on manufacturing(G-automobile) employees' Organizational Culture and Job satisfaction. A proposed model based on previous research was empirically tested via SPSS 25.0 using 349 valid samples collected from current employees of G-automobile Enterprises in Chang Won. The results of the empirical analysis are summarized as follows. First, Entrepreneurship(Innovativeness, Proactiveness, Risk-taking) had direct effects on Job satisfaction. Second, Entrepreneurship(Innovative, Enterprising, Risk-sensitive) had direct effects on Organizational Culture. Third, as a result of analyzing the effect of Organizational Culture on Job satisfaction, it was found that Organizational Culture(Development Culture, Rational Culture) had a significant positive(+) effect on Job satisfaction. The results of this empirical analysis are considered to be related to the rigid organizational culture of automobile manufacturing companies with many male-oriented field workers. In the future, research involving other automobile manufacturers is expected to be needed.

This study aims to investigate the effects of self-service technology (SST) characteristics and consumer characteristics on consumer resistance and satisfaction with SST in restaurants. An online survey was conducted for consumers in their 20s and 50s who used SST at restaurants, and 343 data were used for analysis. As a result, convenience and tech-controllability have a negative effect on consumer resistance with SST, whereas complexity, social risk and relationship orientation have a positive effect. In addition, convenience, entertainment, and tech-controllability have a positive effect on consumer satisfaction with SST, whereas social risk and relationship orientation have a negative effect. This study contributes practically and academically in that it proposes a practical strategy to reduce consumer resistance and increase satisfaction, and identifies the determinants of consumer response to SST. In future studies, an in-depth analysis of consumers' ambivalent responses to SST is required.
