In concert with the development of new materials in the last decade, the need for toxicological studies of these materials has been increasing. These new materials include a group of rare earths (RE). The use of RE nanotechnology is being considered in some green applications, to increase their efficiency by using nano-sized RE compounds, and therefore hazard evaluation and risk assessment are highly recommended. This review was conducted through an extensive contemplation of the literatures in toxicology with in vitro and in vivo studies. Major aspects reviewed were the toxicological evaluations of these elements and metallic compounds at the molecular and cellular level, animal and human epidemiological studies and environmental and occupational health impacts on workers. We also discuss the future prospect of industries with appliances using RE together with the significance of preventive efforts for workers' health. To establish a safe and healthy working environment for RE industries, the use of biomarkers is increasing to provide sustainable measure, due to demand for information about the health risks from unfavorable exposures. Given the recent toxicological results on the exposure of cells, animals and workers to RE compounds, it is important to review the toxicological studies to improve the current understanding of the RE compounds in the field of occupational health. This will help to establish a sustainable, safe and healthy working environment for RE industries.

The risk assessment of thermal hazard to identify chemical or process hazard during early process developments have been considered. The early identification of thermal hazards associated with a process, such as rapid heats of reaction, exothermic decompositions, and the potential for thermal runaways before any large scale operations are undertaken. This paper presents to evaluate the safe operating parameters/envelope for exist plant operations. The assessment of thermal hazard with operating conditions such as amount of process materials, inhibitor, and catalyst on esterification process in manufacture of concrete mixture agents are described. The experiments were performed by a sort of calorimetry with the Multimax reactor system as a screening tool. The aim of the study was to evaluate the thermal risk of process material and mixture in terms of safety security to be practical applications in esterification process. It suggested that we should provide the thermal hazard of reaction materials to present safe operating conditions with cause of accident through this study.

Purpose: The purpose of this study was to identify the effects of infection control performance, infection control fatigue, and social support on the burnout of nurses working at National Safe Hospitals during the coronavirus disease (COVID-19) pandemic, and to use that data to suggest methods to reduce burnout among nurses. Methods: From June 30 to September 30, 2021, data were collected from 144 nurses who both consented to participate in the study and had worked for more than six months in National Safe Hospitals with 300 or more beds in the Gyeonggi-do Province in Korea. Data were analyzed using multiple regression analysis. Results: The factors affecting nurses' burnout at National Safe Hospitals during the COVID-19 pandemic were found to be infection control fatigue (β=.60, p<.001) and social support (β=-.27, p<.001). The explanatory power of these factors was 37.0%. Conclusion: Nurses' burnout at National Safe Hospitals was found to be at a moderate level. Burnout should be reduced through human, material, and administrative support, all of which can reduce infection-control fatigue. It is also necessary to develop both a non-face-to-face social-support-reinforcement program, considering restrictions mandated by infectious-disease pandemics, and a long-term intervention strategy to prevent burnout.

Objectives: This study aimed to compare the regulatory systems for laboratory safety and health management between Korea and Germany and discuss the implications. Methods: Laboratory safety and health regulations for legal enforcement and relevant technical guidelines in Korea and Germany were reviewed. Results: Lab safety and health management is enforced by the Act on the Establishment of Safe Laboratory Environment in Korea. Most provisions focus on supervisory control, that is, the principal's liability is emphasized. In addition, there is a lack of laboratory-specific procedures for safety and health management in the act since it is stipulated that other relevant regulations apply to some technical contents. Non-compulsory technical guidelines for lab safety and health management are also provided by the Korea Occupational Safety and Health Agency (KOSHA) in order to enable researchers to follow safe procedures. There is no independent regulation for lab safety and health in Germany, and it is also governed by several regulations. The German Social Accident Insurance Institute provides technical guidelines on lab safety and health, and these contain more specific content to allow them to be followed more easily compared to the KOSHA guidelines. The most remarkable differences between the regulation of each country were contents of the risk assessment and specific protect measures from hazardous agents. Conclusions: Regulatory control is an essential way to prevent accidents, but it is more important to create an environment in which all stakeholders, including individual lab members, are allowed to participate actively in safety and health management activities.
