        One of the important components of a nuclear fuel cycle facility is a hot cell. Hot cells are engineered robust structures and barriers, which are used to handle radioactive materials and to keep workers, public, and the environment safe from radioactive materials. To provide a confinement function for these hot cells, it is necessary to maintain the soundness of the physical structure, but also to maintain the negative pressure inside the hot cell using the operation of the heating, ventilation, and air conditioning (HVAC) systems. The negative pressure inside the hot cells allows air to enter from outside hot cells and limits the leakage of any contaminant or radioactive material within the hot cell to the outside. Thus, the HVAC system is one of the major components for maintaining this negative pressure in the hot cell. However, as the facility ages, all the components of the hot cell HVAC system are also subject to age-related deterioration, which can cause an unexpected failure of some parts. The abnormal operating condition from the failure results in the increase of facility downtime and the decrease in operating efficiency. Although some major parts are considered and constructed in redundancy and diversity aspects, an unexpected failure and abnormal operating condition could result in reduction of public acceptance and reliability to the facility. With the advent of the 4th Industrial Revolution, prognostics and health management (PHM) technology is advancing at a rapid pace. Korea Hydro & Nuclear Power, Siemens, and other companies have already developed technologies to constantly monitor the integrity of power plants and are applying the technology in the form of digital twins for efficiency and safety of their facility operation. The main point of PHM, based on this study, is to monitor changes and variations of soundness and safety of the operation and equipment to analyze current conditions and to ultimately predict the precursors of unexpected failures in advance. Through PHM, it would be possible to establish a maintenance plan before the failure occurs and to perform predictive maintenance rather than corrective maintenance after failures of any component. Therefore, it is of importance to select appropriate diagnostic techniques to monitor and to diagnose the condition of major components using the constant examination and investigation of the PHM technology. In this study, diagnostic techniques are investigated for monitoring of HVAC and discussed for application of PHM into nuclear fuel cycle facilities with hot cells.

        Occupational safety and health management expenses in the construction industry are statutory and separately included in the cost statement to prevent occupational accidents and health problems. The expenses are determined by multiplying the standard amount by the rate decided according to construction types and scales. However, the current expense appropriation method does not properly reflect the recent changes in the construction industry such as industry size, industry diversification, and social atmosphere about safety reinforcement. This study surveyed 1579 questionnaires in total and analyzed expense execution rate and proportion of each expense category. The expense execution rate was relative higher in complex construction (e.g., heavy construction = 126%, civil engineering = 125%) and long-period project (equal to or over 48 months construction = 133%) compared to general construction (98~116%) and short-period project (less than 48 months construction = 115%). The proportion of spending expenses was higher in the category of safety manager labor costs (25~52%), safety facility costs (22~40%), and personal protective equipment costs (10~25%). The analysis results of the study can be utilized in revising the standard expense appropriation method by reflecting the current usages of the occupational safety and health management expenses in the construction industry.

        It was legislated in Korea that the small-sized enterprise with fewer than 50 employees should appoint at least one managing officer in order to improve safety and health of the employees since 2016. Study on the effectiveness of this legislation is hardly found, however. This study tried to evaluate effectiveness of the regulations for appointing the safety and health management officer in small-sized manufacturing companies and make suggestions to improve it. It was done by pairwise comparison between the level of safety and health achievement of 52 companies before and after the legislation. A scorecard system and questionnaires were devised for assessing the level of safety and health achievement and surveying awareness and practice of the regulation in the field. Results from quantitative and qualitative analyses performed in the study confirm that the safety and health achievement score has increased significantly after appointing the managing officer. It is also revealed that the lack of expertise and motivation of the appointed officer would yield pointless outcomes. Recommendations to make it better the effectiveness of the regulation are: to administrate requirements more strictly to be appointed as a safety and health management officer, to revise the curriculum to train the expertise of the appointed officers, and to expand financial support of the government to settle the safety and health management system.

        The petroleum refinery industry handles a variety of complex chemical substances and employs a large number of people around the world. According to previous research, diseases caused by exposure to chemicals were quite common among workers in refineries until the 1980s. More recently, it is unusual for oil refinery workers to suffer from these serious diseases. The objective of this study was to identify the occurrence level of general diseases and any differences in lifestyle habits of workers in refineries in Korea compared with the general population. In this study, we used the results of health examinations from 2014 for workers at a large oil refinery in South Korea. In addition, based on the results of KNHANES from 2014 as representative of the population, hypertension, diabetes, anemia, hyperlipidemia, liver function abnormality, and kidney function abnormality were calculated using the standardized incidence rate. Hypertension showed a low result with an SIR of less than 1, but a high result in the case of abnormal liver function. The workers’ occurrence rates of hypertension, hyperlipidemia, kidney dysfunction, and anemia were lower than those of ordinary salaried employees. however, their occurrence rate for abnormal liver function was markedly higher. In lifestyle habits, the smoking rate of workers was low while the alcohol consumption rate was quite high. This study has improved the understanding of the health status of workers in a large oil refinery in Korea, and has shown the impact of lifestyle habits related to the work environment on chronic diseases.

        Traditional wastewater research mainly focuses on 1) estimating the amount of waste entering sewage treatment facilities, 2) evaluating the treatment efficiency of sewage facilities, 3) investigating the role of sewage treatment effluent as a point source, and 4) designing and managing sewage treatment facilities. However, since wastewater contains a variety of chemical and biological substances due to the discharge of human excreta and material used for daily living into it, the collective constituents of wastewater are likely a reflection of a community’s status. Wastewater-based epidemiology (WBE), an emerging and promising field of study that involves the analysis of substances in wastewater, can be applied to monitor the state of a defined community. WBE provides opportunities for exploiting indicators in wastewater to fulfill various objectives. The data analyzed under WBE are those pertaining to selected natural and anthropogenic substances in wastewater that are a result of the discharge of metabolic excreta, illicit or legal drugs, and infectious pathogens into the wastewater. This paper reviews recent progress in WBE and addresses current challenges in the field. It primarily discusses several representative applications including the investigation of drug consumption across different communities and the management of community disease and health. Finally, it summarizes established indicators for WBE.

        The objective of this study was to describe the development and testing of an initial ecological health assessment model, based on the index of biological integrity (IBI) using fish assemblages, before establishing the final and currently used model for ecological health assessment, conservation and management of freshwater fish in Korea. The initial fish IBI model was developed during 2004~2006 and included 10 metrics, and in 2007 the final IBI 8-metric model was established for application to streams and rivers in four major Korean watersheds. In this paper, we describe how we developed fish sampling methods, determined metric attributes and categorized tolerance guilds and trophic guilds during the development of the multi-metric model. Two of the initial metrics were removed and the initial evaluation categories were reduced from six to four (excellent, good, fair, poor) before establishing the final national fish model. In the development phase, IBI values were compared with chemical parameters (BOD and COD as indicators of organic matter pollution) and physical habitat parameters to identify differences in IBI model values between chemical and physical habitat conditions. These processes undertaken during the development of the IBI model may be helpful in understanding the modifications made and contribute to creating efficient conservation and management strategies for stream environments to be used by limnologists and fish ecologists as well as stream/watershed managers.

        In order to get as ecological basic data for river management, We estimated health condition of Geum-river mainstream and Mihocheon using vegetation and investigated it for phytosociologic methods. Then, collected data was analysed. Appeared plants in study area were 268 species and the number of appeared plant colonies was 54. Riparian vegetation index(RVI), vegetation health condition assessment method, was evaluated as 38.3 ‘Normal(C)’. Geum-river mainstream's upper stream1(G-U1), upper stream4(G-U4) and mid stream3(G-M3) were highest as 66.7 and Geum-river mainstream's down stream1(G-D1) was lowest by 3.3.Riparian vegetation index under upper stream, middle stream, down stream in Geum-river mainstream and Mihocheon was highest in Geum-river mainstream's upper stream and lowest in Geum--river mainstream's down stream. Riparian vegetation index was negatively correlated with biological oxygen demand(BOD) and chlorophyll-a(Chl-a) in study sites.PCA using species cover degree data of belt transect in each study sites was separated by two groups. One group was consisted of ‘best(A grade)’ and ‘good(B grade)’, the other group was comprised of ’normal(C grade)‘ and ’bad(D grade)’. Cluster analysis was separated by 5 groups: Digitaria ciliaris Koel. community group, Salix gracilistyla Miq. community group, Erigeron annuus Pers. community group, Humulus japonicus Siebold & Zucc., Salix koreensis Andersson, Miscanthus sacchariflorus Benth., and Phragmites japonica Steud. community group, Conyza canadensis Cronquist and Echinochloa crusgalli var. echinata Honda community group. Study sites having similar health condition also was grouped in analysis. These result was similar in PCA. Dominance value of study sites was significantly correlated with vegetation area, structure area, waterway area, spot width, waterway width, bank height and number of species in CCA analysis. As a result, it means that the high health condition sites are dominated by Salix, Fraxinus and phragmites spp. increasing plant diversity and the low health condition sites have a wide structure area simplifing plant diversity by river maintenance work. Thus, the hight health condition area needs to maintain condition through continuous monitoring and the low health condition area needs to restore ecosystem services.
