As social media penetrates more deeply into people's everyday lives, social commerce (a type of commerce that combines SNS features and possibility for commercial transactions) has enjoyed unprecedented growth. Shopping on Facebook is a representative example of social commerce platform that allows consumers to interact with other users, exchange information and purchase products without leaving a Facebook page. Social commerce presents great opportunities for marketers in terms of leveraging social aspects of shopping experience. It also offers a large potential for Korean companies to reach various target markets, as well as establish their presence abroad. Yet, acceptance of social commerce as a legitimate shopping channel has been slow, and consumers are still hesitant to shop via Facebook. This study draws on uses and gratification theory and the concept of perceived risk to examine how different motives for SNS use and the associated types of perceived risks can affect the purchase intention on the platform. Empirical data from 288 young users of Facebook were analyzed. Findings identified two main motives for SNS use: information-related motive and communication-related motive. Information-related motive significantly affected the intention to shop on Facebook, whereas communication-related motive did not have any significant influence. Risks associated with shopping via Facebook included delivery risk, security risk, social risk and economic risk. Overall, consumers perceived a higher level of security and social risk associated with shopping on Facebook. However, only social risk had a significant negative influence on the purchase intention. Awareness and previous experience of buying via social commerce platform positively affected consumers' purchase intention.

The Railway Safety Act of 2014 strengthened the 'Railway Safety Management System' to establish autonomous safety management for railway operators and railway facility managers. Accordingly, it is required to establish and implement risk assessment and safety measures for risk management. However, the current risk assessment system is carried out at the fragmented safety management level within individual fields, which has caused difficulties in establishing and implementing risk assessment and safety measures. In addition, the technical standards of the safety management system stipulate that risk assessment of railway operators is mandatory, so standardized standards for risk assessment of railway facilities and railway vehicle maintenance are needed. Therefore, in this paper, we first verified railway risks by analyzing railway accident data for the last 10 years, and proposed a standardized framework to effectively assess and manage risks through a case study of a condition-based smart maintenance system developed based on railway vehicle maintenance data.

A direct connection between certain lifestyle factors and an increased risk of cancer has already been established. Despite well-documented associations, controversial messages on causes of cancer often appear without taking into consideration their impact on the general population. While mainstream coverage of cancer research is clearly welcome, consideration must be given to the risk of transmitting provocative messages with serious negative consequences for cancer research and public health. We must avoid becoming a breeding ground for the misinterpretation of scientific information. Polemical results can stimulate scientific research and progress, but controversial messages encourage confusion and impotence in an increasingly disoriented population. The correct communication of health messages is at least as important as research on risk factors.

The determinants of the public's nuclear power acceptance have received considerable attention as decisive factors regarding nuclear power policy. However, the contingency of the relative importance of different determinants has been less explored. Building on the literature of psychological distance between the individual and the object, the present study demonstrates that the relative effects of different types of perceived risks regarding nuclear power generation differ across acceptance targets. Using a sample of Korea, our results show that, regarding national acceptance of nuclear power generation, perceived risk from nuclear power plants exerts a stronger negative effect than that from radioactive waste management; however, the latter exerts a stronger negative effect than the former on local acceptance of a nuclear power plant. This finding provides implications for efficient public communication strategy to raise nuclear power acceptance.

Indoor construction site such as building demolition sites, tunnel, vinyl house, and cattle shed are subject to various risk factors such as falling stones, soot and bad odors. However, most of the mini excavators have no cabin that can protect the driver from such risk factors. Therefore, researches on remote control technology of construction equipment are actively conducted as a method for protecting the driver from the risk factors occurring in the working environment. For effective remote control, it is necessary to be able to control the travelling and work using a portable small transmitter. However, due to the limitation of the size of the transmitter, complex operation control is required to control two or more actuators with a single joystick. Also, it is essential to check how remote control characteristics change in various environments such as distance, signal strength, obstacle. Therefore, in this study, an algorithm that can control two actuators simultaneously with a single joystick signal was developed, and a communication method suitable for indoor and outdoor mini construction equipment by analyzing experimentally how the remote control characteristics vary according to various work environments and telecommunication methods proposed.

This study set out to analyze the impacts of convergence products(cell phones, PDAs, IPTV, and portable game consoles) on the consumers' purchase intention and satisfaction. These results of the research model show that usefulness, perceived risk, and communication had significant influences on purchase intention, and usefulness, innovation, perceived risk, and communication on satisfaction. But there were differences according to the product kinds. The results indicate that usefulness, convenience, perceived risk, and communication are the major factors affecting the satisfaction and purchase intention of convergence products and that innovation didn't have much influence on them. And there were small differences among the influential factors according to the kinds of convergence products.

This study has been performed to investigate the risk perceptions of employees in nuclear power plants. A representative sample of 473 employees was surveyed(about 79% response rate). The questionnaire included scales on both risk perceptions of critical five hazards that could be occurring in the nuclear power plants and two psychometric attitudes. Higher risk perceptions between managers and non-managers to five hazards used in this study were entirely obtained from the managers. It was also found that the perceived higher hazards were in the following order: radiation exposure, radioactive release, explosion, fire and radioactive waste. For the controllability, higher risk perceptions to the all factors were obtained from the managers, and higher ones were non-managers in the dread.

In this study, the structural relationship among risk factors, safety motivation, and safety behavior perceived by telecommunications workers was empirically verified. A survey was conducted on field workers at S telecommunications companies in Korea, and the following major results were obtained. First, among the risk factors perceived by telecommunications workers, personal, cultural, and institutional factors were found to have significant positive effects on workers' safety motivation. Second, workers' safety motivation had a significant positive effect on safety behavior. Third, among the risk factors of telecommunications companies, personal, cultural, and institutional factors did not significantly affect workers' safety behavior. Fourth, all risk-causing factors perceived by workers, such as personal, cultural, and institutional factors, indirectly affected safety behavior through safety motivation. This study presents the importance of perceiving risk factors in the workplace to prevent and alleviate industrial accidents by examining the effects of riskcausing factors perceived by carrier workers on safety motivation and behavior.
