Due to recent enhance of safety law and regulations in construction sites, safety inspectors have been more required in construction sites. However, most of them are novice for safety inspection which have not enough experience and skill. Therefore, the novice safety inspector's performance on hazard recognition needs to be improved for effective safety management. The performance of safety inspection is influenced by the inspector's experience and background because the inspection is usually conducted by the inspector's eyes. Therefore, there is a difference in safety inspection performance between novice and experienced safety managers. This study aims to analyze the gap of risk perception between novice and experienced safety managers using quantitative visual data. For this objective, this study conducted eye tracking experiments for novice and experienced group to evaluate cognitive performance of safety risk factors. The results provides the level of safety awareness based on their experience in construction safety. The limitation of this study is a lack of the number of samples used in this study and did not consider the various characteristics of the participants. If these limitations are supplemented in future research, it can be used to develop safety education contents for novice safety managers.

After Fukushima Daiichi nuclear disaster, Korean government banned to import of Japanese fishery products that comes from north region of Japan. As 'fishery product trade dispute' between Korea and Japan is still in progress, consumers have been threatened their food safety. This study is to examine the factors influencing consumer's risk perception to Japanese fishery products and risk taking behavior. Survey was conducted with 1,500 adult during sep-oct 2012. The result can represent the role of affect with risk perception of Japanese fishery product. People who have negative affect to Japanese fishery products have higher risk perception. Also negative affection can influence to risk taking behavior. However the degree of fatalism is not significant factor to risk taking behavior.

The recognition of the risk hazards is a vital step to effectively prevent accidents on a construction site. The advanced development in computer vision systems and the availability of the large visual database related to construction site made it possible to take quick action in the event of human error and disaster situations that may occur during management supervision. Therefore, it is necessary to analyze the risk factors that need to be managed at the construction site and review appropriate and effective technical methods for each risk factor. This research focuses on analyzing Occupational Safety and Health Agency (OSHA) related to risk zone identification rules that can be adopted by the image recognition technology and classify their risk factors depending on the effective technical method. Therefore, this research developed a pattern-oriented classification of OSHA rules that can employ a large scale of safety hazard recognition. This research uses joint reasoning of risk zone Identification and numeric input by utilizing a stereo camera integrated with an image detection algorithm such as (YOLOv3) and Pyramid Stereo Matching Network (PSMNet). The research result identifies risk zones and raises alarm if a target object enters this zone. It also determines numerical information of a target, which recognizes the length, spacing, and angle of the target. Applying image detection joint logic algorithms might leverage the speed and accuracy of hazard detection due to merging more than one factor to prevent accidents in the job site.

Objectives: This study was designed to examine the effect of risk assessment on employee safety behavior in manufacturing workplaces. In addition, this study attempted to explore factors related to the occupational safety and health system in the workplace affect the risk assessment of manufacturing sites. Methods: This research is a cross-sectional study using the Korea Occupational Safety and Health Agency's 2018 Occupational Safety and Health data. The sample for study is 1,967 manufacturing workplaces. Data were analyzed using descriptive statistics, t-test, ANOVA, chi-square test, and hierarchical multiple regression analysis using SPSS (ver.25.0). Results: As a result of the multiple hierarchical regression analysis, it was found that risk assessment had an effect on employee safety behavior (t=4.435, p=<.001). Furthermore, the size of the workplace affected employee safety behavior (t=2.494, p=<.001). In addition, the presence of safety and health management organizations affected employee safety behavior (t=4.301, p=<.001). The factors of the safety and health organization (𝑥²=35.245, p=<.001), the occupational safety and health committee (𝑥²=149.440, p=<.001), and the supervisor (𝑥²=16.472, p=<.001) were identified as factors that increased the possibility of risk assessment in the manufacturing workplaces. Conclusions: In this study, it was found that risk assessment is a factor that increases the level of workers' safety behavior in manufacturing workplaces. Therefore, it is necessary to provide institutional support for activating risk assessment at manufacturing workplaces.

While ginseng is reported to have a wide array of applications, there is growing evidence for its indications in diabetes and vascular disease. A clear connection, however, has not been established between ginseng's composition, dose and its targeted efficacy in humans. We therefore developed and initiated the Korean Red Ginseng Clinical Testing Program for diabetes and vascular function which is an efficacy and safety-based clinical screening model for ginseng. The most efficacious sources, ginsenoside profiles, doses, and modes of administration were examined in sequential, acute, followed by long term, randomized-controlled trials to investigate the efficacy and safety profiles. This review discusses the current state of the clinical research of Korean red ginseng program conducted in Toronto, paving the way for the use of clinically selected ginseng and its ginsenoside fractions in the management of diabetes and vascular diseases.

Consumers are quite worried about food safety because food is one of the most important necessities in everyday life. Many studies have been conducted regarding the food safety issues, however, most researches have focused only on a limited range of risk factors and used only quantitative survey methods. The purpose of this study was to investigate consumers' perceptions of the risky components of food safety and how the perceptions have been formed. For this study in-depth interviews were conducted. For the interviewees, nine housewives, who are in their 30s to 50s, were selected taking into consideration their age, education level, number of children, and employment status. Results showed that the risk factors many consumers worried about were agricultural pesticides, MSG, food additives, GMO, Mad Cow Disease, preservatives, and growth hormones, etc. Consumers were worried about the risk of the retail process the most because they thought it was not informed and controlled well. Consumers tend to worry much more when the risks are involuntary, uncontrollable, unreliable, and have a gradual negative effect. Some of the food safety-oriented behaviors of consumers were also investigated.
