Purpose : This study examines dental hygienists’ emotional labor, job satisfaction, and turnover intention and defines how this emotional labor affects job satisfaction and turnover intention in hospitals. Methods : Among the dental hygienists currently working for the dental department in hospitals and clinics located in Busan, South Korea, 216 dental hygienists who understood the purpose of this research and agreed to participate were instructed to answer a self-administered questionnaire from April 1 to April 30, 2019. A statistical analysis was subsequently conducted on the responses using the SPSS Win 23.0 program. Results : Emotional labor and job satisfaction showed a negative relationship; thus, as emotional labor was low, job satisfaction was high. Moreover, emotional labor and turnover intention were found to be positively correlated, while job satisfaction and turnover intention were shown to be negatively related (p<0.01). Conclusion : The present study demonstrated that the emotional labor of dental hygienists affects job satisfaction and turnover intention. The results suggests that through systematic organization and human resource management, hospitals should design and implement in practice programs to increase dental hygienists’ job satisfaction. In addition, these hospitals should secure compensation systems that are motivating enough to enhance the severe emotional labor of dental hygienists to decrease turnover intention. As another method to lower turnover intention, dental hygienists may attempt to resolve emotional disharmony with their own problem-solving methods; however, it is necessary to develop and support organizational culture for the improvement of their working environment.

This study proposed a low temperature hydrothermal carbonization to treat and recycle sewage sludge and determined the optimal conditions for the biochar production. The physical and chemical properties of biochar were analyzed and its sorption capacity for heavy metals was evaluated. To produce biochar, 50 g of sewage sludge was heated at 220, 230, and $240^{\circ}C$ for 1, 2, 3, 5, 8, and 10 hours in a reactor. The optimal conditions to produce biochar was $230^{\circ}C$ and 8 hours. Sorption capacity tests were conducted for arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), zinc (Zn) and nickel (Ni). Among them, lead was shown the highest heavy metal adsorption efficiency of biochar, followed by copper, cadmium, zinc, and nickel, but arsenic was hardly adsorbed overall.

When processing the biomass by Hydrothermal carbonization (HTC), a slow pyrolysis process, it produces bio-gas, biooil, and biochar. Among these end products, biochar is known for isolating or storing carbon and being used as a soil amendment. In this study, the characteristics of biochar generated by HTC at $250^{\circ}C$ for 1 hour, 2 hours, 3 hours, and 20 hours with synthetic food wastes and wood wastes were analyzed for potential uses in soil contaminated with heavy metals. The yield of biochar (weight %) increased when the ratio of wood wastes increased and showed a decreasing tendency as reaction time increased. Elemental analysis of biochar based on various conditions showed a maximum of 70% carbon (C) content. The carbon content showed an increasing tendency with the increase of wood wastes. Iodine adsorption test was peformed to determine the optimum reaction condition, which was 15% wood waste for mixing ratio and 2 hours for reaction time. Using biochar generated at the optimum condition, its capability of adsorbing heavy metals (Cd, Cu, Pb, Zn, Ni) was evaluated. It was concluded that lead (Pb) was removed efficiently while zinc (Zn) and nickel (Ni) were hardly adsorbed by biochar.

Hydrothermal carbonization (HTC) is a carbonization method of thermochemical process at a relatively low temperature (180-250℃). It is reacted by water containing raw material. In this study, it was selected for effective disposal method of food waste because food waste in Korea has large amount water. 5 kg, 10 kg, 15 kg of food waste were reacted for 6 hours at 200℃ for selecting the optimum amount of raw material. Since the derived optimum amount, food waste was reacted for 2 hours, 4 hours and 6 hours at 200℃ and 1.5 MPa. After carbonization, it was analyzed to evaluated the properties by ultimate analysis, iodine adsorption, BET surface area and SEM. After analyzing the characteristics, it can be utilized as a basic data for applied.

Objectives: This study was conducted to analyze the trends of government R&D (R&D) projects related to laboratory safety over the past 20 years. Methods: We collected publications from various databases(DBs) with words such as laboratory(ies), lab(s), researcher(s), laboratory worker(s), safety, environment, hazard(s), risk(s), and so on. Selected publications were analyzed by the research funds and the number of projects according to the investment subject and research characteristics. Results: About 93% of the total R&D budget went to government policy projects, not scientific research. Second, from the perspective of ‘safety management activities’, most of the research is related to management and inspection at the organizational level. Issues that need to be discussed at the national level like policy governance are not included. Third, focusing on the ‘safety management cycle’, there were few studies related to ‘prediction’ or ‘post-response’. Fourth, when an analysis framework combining the perspectives of ‘safety management activities’ and ‘safety management cycle’ is applied, most of the budget is spent on infrastructure such as digital management systems, whereas basic knowledge for prevention and production of evidence was very few. Conclusions: In order to prevent policy planning without policy evaluation, implementation without strategy, and evaluation without evidence, it is necessary to expand investment in empirical research on risks, research on the effectiveness of current application methods, and research on theory development. The government budget for laboratory safety-related projects should be managed separately from the R&D budget for scientific research. Although less than 5% of the budget allocated to scientific research is the total budget, an optical illusion occurs because both the project budget and the scientific research budget are counted as R&D budgets.

Dust particles have been generated from the soil exposed to the atmosphere via desiccation process. There are several ways to reduce dust generation from the exposed ground. Among various means, polymer solution has been received a great attention due to easy application and effectiveness of its results. In this study, the soil obtained from the ground in Seoul Women’s University was mixed with 3 different polymer solutions; polyacrylamide, polyacrylic acid and polyacrylamide copolymer with polyacrylic acid. In addition, sodium lauryl sulfate, a surfactant which helps the aqueous polymer molecules penetrate into the soil particles and adsorb to their surfaces and 1,6-diisocyanatohexane, which is an additive to solidify the soil particles for the strength enhancement were mixed to investigate their effects on soil desiccation. The desiccation durations were 44 days at room temperature and 12 days at 50oC, respectively. The half-lives and desiccation rate constant have been determined from the 1st order reaction. As a result of desiccation at room temperature, soil mixed with 1% polyacrylamide, surfactant and an additive showed 8.27 days while 3.33 days with water as a control. It was found that the surfactant enhanced the sorption of polymer molecules in aqueous phase to reduce the water evaporation from the surface.
