Radiation and its various industrial applications have been growing at approximately 10 percent per year for the past decade in Korea. As a result, the importance of the Education and Training (E&T) in radiation protection is of upmost importance. This paper is intended to investigate the present status of the E&T on radiation protection and safety in Korea and to draw up the improvements of the E&T courses required for building the national radiation safety infrastructure. For these purposes, the E&T data from the six major domestic organizations providing radiation protection training courses were investigated and analyzed. Each of the organizations is offering several kinds of E&T courses based on their own specific functions. These organizations have administrative facilities equipped with the latest technology for E&T in radiation protection. The E&T courses mainly cover the training courses for radiation workers, radiological emergency staff, license applicants, license holders, and regulatory staff. In 2010, a total of 58 E&T courses were carried out across six organizations. The conclusions make a number of observations highlighting challenges such as: establishing a formal feedback mechanism, introducing more practical training sessions, developing training courses tailored to the job categories and target audiences, and designing education and training courses in radiation protection that comply with current obligations as well as future requirements.

Technology development of modern society reduces times, costs and labor costs but demands work forces requiring expert knowledge on technology. Consequently knowledge worker becomes important. Not changing into a specialist acquired expert knowledge, people can't survive in competitive society. Therefore, the purpose of this study is to grasp the actual condition of private security industry and to examine problems. The final goal is to find the way to improve the professionalism of workers in private security industry. First. Now we must make up for the subject for examination actually and be in a triangular position and complement a professional materials for teaching. At the same time it must strengthen the education using advanced instruments seek to Total Security System. Moreover it is demanded 'institutional supplement of security guard instructors' which means job training for security guard instructor Second. On the job training which can deal with a state of emergency through 'security guard training' with a theory and an actual training must be strengthen. Also, most security guards have low understandings and interests because their ages are from 50's to 60's. Accordingly proper education must be offered to security guard. Third. Certification system of the private security guards are needed to fix the problems on an indiscreet issue and an abuse of license through deliberation on the security license. Fourth. Universities must find a new market to minimize the squandering of human resources because of oversupply and reduce the personnel. Also with enhancing the employment rate through specialized education, universities must offer an education which keeps pace with the times for not an entrance strategy but a long-term development. Effort for education of specialist will produce an improvement in business quality and improved services produce a customer satisfaction. A customer satisfaction will produce a fame of a successful company and positive images in market area. Finally the private industry will be developed by productivity improvement.

For the prediction of the ventilation rate for removing the non-isothermal concentrated fume from the semi-enclosed space, the computational fluid dynamics (CFD) analysis was done. Securing the proper ventilation conditions in emergency state such as in fire is crucial factor for the protection of the resident in the space. In the analysis for the determining the proper ventilation rate, the experimental study had the limitation for simulating the versatile conditions of fume development. The theoretical and computational method had been chosen as the alternate tool for the experimental analysis. In this study, the CFD analysis was done on the defined model which already had been done the experimental analysis by the previous workers. By comparing the prediction on the plume heights and the ventilation rates by the CFD analysis at, and in the parametric model of $1m^3$ with those of the previous experimental works, the feasibility of the computational analysis was evaluated. For the required ventilation rate analyzed by the CFD analysis was over predicted in 7.1% difference with that of the experimental results depending on the different plume height. With the comparison with the analytical Zukoski model at, the CFD analysis on the ventilation was under predicted in 8.3%. By the verification of the feasibility of the CFD analysis, the extended analysis was done for getting the extra information such as the water vapor distribution and $CO^2$ distribution in the semi-enclosed spaces.

Since April 2012, more than 1,600 laboratory-confirmed human infections with Middle East Respiratory Syndrome Coronavirus (MERS-CoV) have been reported, occurring primarily in countries in the Arabian Peninsula; the majority in Saudi Arabia. The MERS outbreak in Korea, which began in May 2015 through the importation of a single case who had recently traveled to Bahrain, the United Arab Emirates, Saudi Arabia, and Qatar. As of November 28th, 186 secondary and tertiary cases had been reported; 38 deaths, mainly associated with underlying chronic illnesses, were reported. One case was exported to China and has been recorded as the first MERS case in China. Thirty-seven confirmed cases were associated with the index case, who was hospitalized from May 15 to May 17. Emergency room at one of the nation's largest hospitals had been affected by hospital-to-hospital and intra-hospital transmissions of MERS-CoV, resulting in an outbreak of 90 infected patients. The vast majority of 186 confirmed cases are linked to a single transmission chain associated with health facilities. The median age of patients is 55 years, with a range of 16 to 87 years. The majority (61%) of patients are men. Twenty-five (14%) of the cases involve healthcare workers. The overall median incubation period was six days, but it was four days for secondary cases and six days for tertiary cases. There has been no evidence of airborne transmission and sustained human-to-human transmission in communities. Intensified public health measures, including contact tracing, quarantine and isolation of all contacts and suspected cases, and infection prevention and control have brought the MERS-CoV under control in Korea. Since 4 July no new cases have been reported.

Introduction: An unexpected death was reported in a beginner immediately after starting the work at a plating factory. After the incident, air sampling was performed using a simulation of the situation as it had been at the time. Methods: To evaluate the airborne concentration of hydrogen cyanide, a total of six samples were collected: one personal sample, three area samples, and two background samples (office and outdoors). Hydrogen cyanide measurement was performed according to the standard sampling protocol recommended by the U.S. NIOSH (National Institute of Occupational Safety and Health). Results: The highest concentration of hydrogen cyanide was 0.938 ppm measured in a sample collected from the plating bath area with local exhaust ventilation. This value was approximately 20% of the ceiling occupational exposure limit. The personal sample showed a concentration of 0.135 ppm. Samples collected near the bath in which the incident occurred and a dehydrator showed hydrogen cyanide concentrations of 0.236 ppm and 0.101 ppm, respectively. Hydrogen cyanide was not detected in the background samples (office and outdoors). Conclusions: It is necessary to use proper ventilation systems and respirators in plating factories to prevent acute poisoning. Furthermore, it is important to educate and train new workers dealing with toxic substances.

Introduction: The risk of experiencing psychiatric symptoms related to the COVID-19 pandemic is high among healthcare workers whose occupations are in public health, emergency medicine, and intensive or critical care. Materials and methods: A cross-sectional study aimed to assess the prevalence of fear of COVID-19 among 411 frontline Egyptian physicians during the COVID-19 pandemic; identify determinants and predictors for fear of COVID-19; determine the impact of fear of COVID-19 on job satisfaction; and detect the impact of fear of COVID-19 on turnover intention. Three standardized scales (fear of COVID-19, job satisfaction, and turnover intention scores) were used for data collection via online Google Form. Results: Regarding fear relating to the COVID-19 pandemic, 16.5% of the study subjects were classified as experiencing a severe fear level, while 78.1% experienced a moderate degree. A significant association between the level of fear relating to COVID-19 and the work department. The highest degree of fear is in a general-educational-university facility. Regarding job satisfaction, 42% of those having a severe level of fear are dissatisfied. Fear of COVID-19 is negatively associated with job satisfaction while positively significant correlated with turnover scores, a positive significant predictor of turnover intention. Job satisfaction is negatively associated with turnover intention; a negative significant predictor of turnover intention. Conclusions: Frontline Egyptian physicians reported higher levels of fear relating to the COVID-19 pandemic (moderate to severe). Increased fear levels relating to COVID-19 have a relationship with lower levels of job satisfaction and higher levels of job turnover.
