Objective; This study was conducted to ensure the safety of drinking water for soldiers by surveying on contamination levels of Norovirus in unerground/surface water for Military use in Gangwon Province and to acquire Norovirus analysis technology in water. Method; Among the water sources used by the front unit of the 0 Corps, a total of 67 water supply sources that are found to be vulnerable to microbial contamination, such as those that do not have automatic residual chlorine injection devices installed or where pathogenic microorganisms were detected as a result of regular water quality tests were selected. Samples were collected by filtering and adsorbing more than 500 liters of water with a standard filter apparatus and the pH, temperature, turbidity, and residual chlorine levels of water samples were measured to investigate the characteristics of water quality at the site, but the microbiological examinations for total coliforms and E.coli were conducted in the laboratory independently. We pre-treated the samples and conducted gene analysis(RT-PCR and reverse transcription-PCR process) followed by electrophoresis. After checking the bands that matched the positive control, the positive sample was sent to the specialized institute for sequencing. Results; In this study, Norovirus type GI.10 was detected in one of 67 water sources. The detection rate of Norovirus among the total was 1.5%, of which the detection rate for underground water was 1.7%. Conclusion; In order to ensure the safety of underground/surface water to drink for Military use, it is necessary to steadily conduct monitoring examinations on Norovirus contamination as well as legal inspections. Norovirus analysis technology of water obtained through this study will also help prevent water-borne disease more preemptively and timely.

Objective Among military sports facilities, most futsal stadiums have artificial turf floors. Synthetic resin fibers and filler rubber powders that make up artificial grass contain various harmful chemicals, but this survey study was needed because no fact-finding survey was conducted on their harmfulness. Method Of the 1,068 artificial turf fields installed in the army, 24 were selected according to the year of installation, and solid samples of artificial grass constituents were collected. Heavy metals(4 types), soluble metals(14 types), phthalates(6 types), polycyclic aromatic hydrocarbons(18 types), and total volatile organic compounds(4 types) were quantitatively analyzed using a precision analyzer. Results Hazardous chemicals were detected in 9(37.5%) of the 24 artificial turf facilities to be measured, and in 3 of them (12.5%), they exceeded the permissible standard. There was no correlation between the year of installation of artificial turf and the concentration distribution of harmful chemicals. Conclusion As a result of this investigation, harmful chemicals in some items (PAHs) of the artificial turf facilities of the Army were over-detected, but this does not mean that they are directly related to exposure and health problems for soldiers. It is only a basic environmental factor in risk assessment for the possibility of exposure to hazardous chemicals. Therefore, it is necessary to conduct related studies such as direct exposure evaluation of artificial turf facility users through the skin and respiratory tract or a comparison of human metabolic exposure index substances in high-risk soldiers and the control group for hazardous chemicals.

Objective We intended to examine the overall reality of military working environment and health management for workers and to suggest practical improvement and management plans. Method Current laws such as the Occupational Safety and Health Act and the military work environment and worker health management directives were compared and reviewed, and related literature was investigated. Results There are many factors that need to be systematically established and improved in the current military working environment and health management for workers, and it is necessary to introduce a sustainable and effective management method. The most basic, important, and precedent is to secure accurate material safety data sheets and use it in connection with on-site surveys, environmental measurements, and occupational health examinations based on it. In addition, an organization composed of experts in each field will continuously visit and provide in-depth consulting so that practical occupational health management can be achieved consistently. Conclusion In the Occupational Safety and Health Act, a systematic and diverse system for the workplace and workers has been established for a long time. However, in the military, the application of this is still in its infancy, so a policy that can be applied in stages is needed. Military organizations have a systems in place that allow them to communicate and report quickly and accurately through intranets, which is much better than society, so it's easy to build up.

군부대 급식시설 취사 중 공기 질 및 유해인자 정량평가

Objective: Recently, health impairments of workers exposed to cooking fumes for a long period of time have become a social concern. The aim of this study was to evaluate various harmful factors quantitatively, which could be produced during the cooking process at selected military catering facilities. Method: Six military cooking workplaces were selected as sample sites, and the samples for air pollutant measurement were collected while preparing lunch. The samples were collected using direct reading equipments or personal sample collectors. Air pollutants including fine dust, ultrafine dust, polycyclic aromatic hydrocarbons (PAHs), total volatile organic compounds (TVOCs), carbon monoxide (CO) and carbon dioxide (CO2) were analyzed quantitatively. Results: The concentrations of fine dust and ultrafine dust were higher than the recommended general indoor air quality limitations of the Korean government. Otherwise, there were no factors that exceeded the current government's standards. The criteria of the statutory standards for indoor air quality and the exposure criteria for chemicals and physical factors of the relevant law were referenced. Conclusion: The overall air quality at selected military catering facilities was relatively good, however, harmful factors such as cooking fumes generated during the cooking process can vary depending on multiple factors such as daily menus, cooking methods and operating conditions of ventilation facilities. So, to improve workplace environments, appropriate operating standards applicable to cooking facilities should be developed and continuously monitored.
