The purpose of this study was to investigate the influences of tangible clues on university students' perceived risks and satisfaction at family-restaurants in Seoul. The performances of 3 tangible clues(physical evidence, employee, service process) negatively influenced the student's perceived risks. This result indicated that tangible clues can reduce the negative characteristics of service (intangibility, inseparability, perishability and variability) toward student customers at family restaurants. Meanwhile, financial risk, performance risk and social risk negatively influenced their overall satisfaction. Performance risk had the strongest negative influence on student customers' overall satisfaction, indicating that university students were much more interested in performance and utility about menu, food and service quality than in other factors at family restaurants. As a result, food-service corporations need to manage suitably various tangible clues as an important marketing strategy to diminish their customers' perceived risk and raise their satisfaction.

This study examines the impact of perceived risks for smart shoes based on purchase intention by type of smart shoes as well as how they are mediated by fashion innovativeness and technology innovativeness. It also compares the differences between awareness, interest and perceived risk of smart shoes by gender and age. This study was conducted based on men and women in their 20s to 50s who provided 246 samples for data analysis using SPSS 25.0. The results show significant differences in the awareness, interests and perceived economic risk of smart shoes by gender and age. The perceived performance risk had a positive effect on the purchase intention of smart shoes for GPS. Perceived aesthetic-psychological risk had a negative effect on all types of smart shoes. Perceived economic risk had a negative effect on the purchase intention of smart shoes for entertainment; in comparison, perceived social risk had a positive effect on the purchase intention of smart shoes for GPS and entertainment. Fashion innovativeness and technology innovativeness also mediated the relationship between perceived economic risk as well as the purchase intention of smart shoes for healthcare, GPS and entertainment.

The relationship between compliance with behaviors recommended to prevent the spread of COVID-19 and media exposure, negative emotions, and risk perception was examined using regression analyses of data from KAMOS, a nationally representative survey of South Korean adults. The strongest predictor of preventive behaviors in general was negative emotions, which had the largest βh (.22) among the independent variables considered. The eight negative emotions, identified using factor analysis of a series of 11 emotions, were anger, annoyance, fear, sadness, anxiety, insomnia, helplessness, and stress. Negative emotions themselves were influenced most strongly by the respondent's anxiety over social safety (βe=.286), followed by prediction of COVID-10 spread (β=.121, p<.001) and perceived risk of COVID-19 infection (β=.70, p=.023). Females (β=-.134) and those who felt less healthy (βo=-.097) experienced more negative emotions. Media exposure and increased media exposure both have significant relationships with negative emotions and both a direct and indirect impact on the adoption of preventive measures. Women, older people, and healthier people perceived greater risks and engaged in more preventive behaviors than their counterparts.

A nuclear power plant (NPP) is a highly complex system-of-systems as manifested through its internal systems interdependence. The negative impact of such interdependence was demonstrated through the 2011 Fukushima Daiichi nuclear disaster. As such, there is a critical need for new strategies to overcome the limitations of current risk assessment techniques (e.g. the use of static event and fault tree schemes), particularly through simulation of the nonlinear dynamic feedback mechanisms between the different NPP systems/components. As the first and key step towards developing an integrated NPP dynamic probabilistic risk assessment platform that can account for such feedback mechanisms, the current study adopts a system dynamics simulation approach to model the thermal dynamic processes in: the reactor core; the secondary coolant system; and the pressurized water reactor. The reactor core and secondary coolant system parameters used to develop system dynamics models are based on those of the Palo Verde Nuclear Generating Station. These three system dynamics models are subsequently validated, using results from published work, under different system perturbations including the change in reactivity, the steam valve coefficient, the primary coolant flow, and others. Moving forward, the developed system dynamics models can be integrated with other interacting processes within a NPP to form the basis of a dynamic system-level (systemic) risk assessment tool.

The benefits and risks of whole body vibration (WBV) based acceleration training on the human body have been documented for many years. WBV training has been shown to increase muscular strength, explosive power, bone strength, performance, mobility, cardiovascular function, circulation and anabolic hormone level and so on. The purpose of this review is correct understanding and application of WBV training. Without proper understanding, rather, to apply WBV to the human body can be fatal harm, and therefore know that what is vibration and has advantages and disadvantages. If there is anything positive side there is bound to the negative aspects. In this regard, WBV training can have a positive impact on the already confirmed by several studies and also, there have been scientifically proven. But still we are part of a scientific approach that is acceptable even to keep in mind that you will always coexist. Once again, the effect of WBV with a physical stimulus that risk and should be remembered. In addition, given the momentum and how to exercise and well-being well aware that vibration exercise as a way to think of how not to be familiar with.

In the era of the 4th Industrial Revolution, smart technology being considered to improve productivity breakthroughs is in the spotlight as a means to replace traditional construction technology in the construction industry. However, various problems are occurring in construction sites using smart technology and causing negative impacts on construction projects. Therefore, the objective of this study is to identify risk factors that occur when smart technologies are used in construction projects. To achieve this purpose, this study investigated the difficulties at construction projects using smart technology, and risk factors were derived based on site surveys and literature. The risk factors were measured by experts, and then a total of 19 risk factors was derived by exploratory factor analysis. As a result, risks were classified as 5 factors, the institutional factor is the most difficult response, and the government needs anticipative system improvement and a long-term plan. The research findings provide practical implications for construction experts trying to apply smart technology in construction sites and construction policy-makers to revitalize smart technology.

Purpose: This study's goal is to investigate how perceived risk of Japanese electronic product affect the negative emotion and the avoidance intentions. In addition, this is difference in the effect of perceived risk on negative emotions and avoidance intentions according to the presence or absence of substitutes. Research design, data and methodology: Perceived risks of Japan products are decided by four dimensions, they are economic risk, social risk, psychological risk and physical risk. The reach model is made by the theory of risk-avoid. We requested this survey to 5808 customers by panel and web site, received 559 replied. We used 528 questionnaires excluding unreliable data. For the analysis, smart PLS is used. Results: Psychological risk has influence on negative emotion and avoidance intension. Social risk and physical risk affected negative emotion, but did not directly affect avoidance intention. Economic risk affects avoidance intension, but it has no effect of negative emotion. The existence of Japanese products' substitute only effects the relationship of economic risk and avoidance intention. Conclusions: Korean consumers behavior their buying and using of Japan product as financial benefit and satisfaction, not only risk. It is suggested that Korean company should make and develop unique product with good price.

주요국에서는 증가하는 노인운전자의 교통사고 경감을 위해 연령별 자동차 사고 위험도를 분석한 후, 위험도가 높은 고령자의 교통사고를 경감하기 위한 다양한 제도를 시행하고 있다. 최근 우리나라 교통사고는 감소하고 있지만 65세 노인운전자의 교통사고는 빠르게 증가하고 있음에도 불구하고 노인운전자의 자동차사고 위험도에 대한 실증연구가 부재하고, 관련제도 개선이 이루어지지 않고 있는 실정이다. 이에 본 연구에서는 우리나라 운전자들의 연령별 자동차사고 위험도를 분석하였는데, 25세 미만 연령층을 제외하고 65세 이상 노인운전자의 자동차사고 위험도가 가장 높은 것으로 분석되어졌다. 세계에서 가장 빠른 인구고령화를 경험하고 있는 우리나라에서도 주요국처럼 노인운전자에 대한 운전교육 및 운전면허 재발급 자격을 강화할 필요가 있겠다. 또한 노인운전자를 배려한 도로표지판 개선과 노인운전차량 스티커 부여, 그리고 자가운전 대신 대중교통을 운전하는 노인들에 대해 인센티브를 제공하는 유인체계의 변화가 필요하다.
