  • Detecting and assessing human-related risks is critical to improve the on-site safety condition and reduce the loss in lives, time and budget for construction industry. Recent research in neural science and psychology suggest inattentional blindness that caused by overload in working memory is the major cause of unexpected human related accidents. Due to the limitation of human mental workload, laborers are vulnerable to unexpected hazards while focusing on complicated and dangerous construction tasks. Therefore, detecting the risk perception abilities of workers could help to identify vulnerable individuals and reduce unexpected injuries. However, there are no available measurement approaches or devices capable of monitoring construction workers' mental conditions. The research proposed in this paper aims to develop such a measurement framework to evaluate hazards through monitoring electroencephalogram of labors. The research team developed a wearable safety monitoring helmet, which can collect the brain waves of users for analysis. A bispectrum approach has been developed in this paper to enrich the data source and improve accuracy.

  • Various leading indicators of safety culture have been advocated for proactive actions as lagging indicators have limitations in reflecting the attitudes and behaviors due to their reactivity and low sensitivity. This study proposes a model of incident-reporting culture (IRC) and determines the influence of the components on incident-reporting rate (IRR) in order to develop proactive indicators of safety culture. A questionnaire survey was administered to 614 workers at a chemical company in Korea, and the internal psychological aspects were explored by using perceptions, attitude, and backgrounds. The relationship between these factors and IRR was quantitatively confirmed. The workers are more reluctant to report injury than property damage, the perception of severity is the most influencing factor, and most property damages are reported regardless of worker's willingness. These features should be prioritized when improving IRC, and the criteria of IRC need to be aligned with safety culture.

  • The purpose of this study was to present the direction of the safety manual in the food service industry kitchen. The accident rate in food industry kitchens is around 87.2%, it meaning nearly 9 workers have accident among 10, considered to be very high. The most common accident is a knife cut wound (84.7%). And burns caused by hot water and oil (74.4%), then shown slip and falls (28.1%). The degree of fulfillment of kitchen safety awareness and safe environment varied based on gender, in which male are considered more likely to suffer from accidents than women. The level of safety perception varies between workers at different career points. Workers with 1~3 years of experience suffer the highest rate of accident, while workers with 7~10 years and more of experience are believed to be at lower risk of accident. Restaurant type did not exhibit a significant influence on accidents cases, although differences in the adoption of personal safety, even partially, were discovered, at significance of 0.01 < 0.027 < $0.05^*$. Based on these results, this paper has suggested preventive safety management validation model the food service industry based on kitchen management and incident management, and presented steps necessary.

  • Purpose of this study is to analyze actual perception of security business of security workers centering on employees working within building and to improve accomplishment of works for security workers. For this, first, activities of security workers are discussed. Second, perception of employees of companies for the necessity of security workers, non-necessity of security workers, qualification requirements of security workers for improving business recognition were established as a framework of the study. Changes for recognition of security works in modern life are a little falling behind compared to unstopping economic development and diversifying job classifications. Even at present, expression of security works is still regarded as manager of facilities or apartments in the past. In other words, it is recognized as a simple change of title and names from apartment guard to security workers. Security works in the modern job classification is settling down as a professional field of facility management and as a part of various controls such as protection and security and its field is also expanding. It is a professional job with the purpose to analyze and prevent diverse criminal actions occurring in the society and also to introduce alternative measures with the role to prevent accidents to be occurred in variety in advance instead of simple working format taking a fixed guard post. Area of security works for the purpose of maximizing necessity of security works shall have equipped with deployment of professional security workers, consideration of business satisfaction of security workers, prevention education for rapidly changing safety accidents, and substantiality in the field. We expect to have more sophisticated area of security works with ceaseless efforts and with instillation of recognition of professionalism by security workers themselves.

  • To describe the comparative awareness between media and industry, we conducted a survey with a professional group including 28 food safety managers at food corporations and 17 food journalists to find out the differences in perception of 'reporting terms' and 'correspondence terms' when food safety incident occurs. We surveyed by questionnaire methods and did the statistical analysis by SPSS. The results showed that 70.6% of the journalists and 92.9% of the corporation workers answered 'yes indeed' about the question whether the media has a great influence when food safety incident occurs. In the perception that use of the stimulating terms of the media was the cause of company damage, 83% of the corporate workers answered 'yes indeed', and 70.6% of the journalists answered 'yes'. It means that both groups agreed on stimulating terms causing company damage. In the question whether the 'reporting terms' of the media and the 'correspondence terms' of the government and academia made a difference in the consumers' perception and the spread of the incident, 92.9% of the corporate workers and 35.3% of the journalists answered 'yes indeed'. It means that both groups showed a common opinion that the difference in choice of words expanded the perception of consumers, and the spread of the incident. However, the corporate workers agreed with this in a more serious manner than the journalist group. In standardization of 'reporting terms' and restricting use, corporate workers were overall at a positive stand while journalists showed a big difference in opinion within the group. In conclusion, it is necessary to establish a measure to standardize the terms used by corporations, journalists, and professionals in order to decrease the differences of terms and the damage of consumers and the company when food safety incident occurs.

  • Construction industry has a relatively higher industrial accident rate than other domestic industries. Thus, to reduce the accident rate, researches on the methodology of worker's safety education combined with new technologies like IT technology have increased. In the light of workers' safety information provision, this study develops a VR(Virtual Reality)-based construction site using the BIM(Building Information Modeling) data. The target structures and geographical features are included in the VR-based construction site where the construction machinery model and worker model are also created using a game engine. For highly effective provision of safety information, video clips with suitable captions corresponding to working processes were made with proper screen directing. They should be appropriately connected to correct worker's operations to improve the work commitment level, sense of reality and inducement of interest. From this scenario, the 3D VR-based construction site, which can be experienced through a VR equipment, was created and in the same platform, the safety information was provided by the video clip combined with the suitable captions. Although the real construction site involves various requirements depending on field situation and the expertness and experience of workers are not consistent, the developed safety information provision based on the VR construction site is expected to effectively reduce the incomplete factors leading to construction accidents by improving the worker's perception of workplace safety.

  • To identify the relationship between types of employment(regular and non-regular group) and departments classification (administration, product and research group) and the levels of recognition of chemical substances, a total of 117 workers in cosmetics workplaces. Mainly, regular group and research group showed higher recognition of chemical substances (PPE, ventilation, chemical management, hazards in handling chemicals, skin contact) than non-regular group and administration, product group, but In some cases, production and administrative groups were high. Descriptive statistics(SAS ver9.2)was performed. the results of recognition of chemical substances were analyzed the mean and standard deviation by t-test, and anova, (P=0.05). These results cosmetics manufacturing workplaces have normal level of the perception of chemical substances. In most of the employment types, the regular workers showed high recognition, and the working departments showed high recognition in the research and production groups. Therefore, OEM and ODM cosmetics manufacturers regularly identify characteristics and needs of workplaces and workers, and suggest the development of experience and practiced education programs and risk assessment tools that can raise worker awareness.
