Purpose - The current study attempts to enhance competitiveness by improving Chinese restaurant chefs' work environment and analyzes its effect on work environment and burnout. Also, this study analyzes to see if there is moderation role of enthusiasm between work environment and burnout. Based on analyzation, the present study aims to suggest more effective measure of human resource management by reducing burnout and turnover through providing chefs with more stable and consistent work environment and through their enthusiasm. Research design, data, methodology - Surveys were distributed to chefs working in Chinese restaurant in Seoul and Kyunggi region. Total of 500 surveys were distributed between September 1, 2017 and September 20, 2017 (about 20 days), and 417 surveys were returned to be used in the analysis. Results - As a result of testing effect of chefs' work environment on burnout (1) welfare environment, personal environment, and institution environment had significant effect on loss of accomplishment. (2) welfare, personal, and institution environment had significant effect on deindividuation. (3) welfare environment and institution had significant effect on emotional deprivation while personal environment did not. Second, as a result of analysis on moderation role of obsessive enthusiasm between Chinese restaurant chefs' work environment and burnout (1) as a result of interaction between work environment and loss of accomplishment, personal environment had significant effect while welfare environment and institution environment did not. (2) As a result of interaction between work environment and deindividuation, welfare, personal, and institution environment did not have significant effect. (3) As a result of interaction between work environment and emotional deprivation, institution environment had significant effect while personal environment and welfare environment did not. Conclusions - There is manpower shortage due to poor work environment of Chinese restaurant. Studies that are not limited to work environment are needed to more efficiently utilize human resources.

To investigate the forecasting of plant disease and insect for an agricultural complex and farm in environment-friendly cultivation of Rice, environment-friendly agricultural five complexs and five farms were selected in Youngam and Naju area, Jonnam, Korea. Preventation objects of plant disease and insect were leaf blast, neck blast, sheath blight, bacterial leaf blight, and hopper. Factors of sheath blight occurrence in environment-friendly agricultural complex were a fast transplanting time and a narrow planting density. Bacterial leaf blight in rice occurred severely in the area under water. Rice growth in environment-friendly agricultural complex was decreased heavy drying by hopper appearance.

With a view to the residential environment plan to improve the quality of life and health status of dwellers, the purpose of this study is to explore the co-relation between pedestrian environment and health performance in apartment complexes and to analyze the residents' evaluations on pedestrian environment for 'pedestrians-friendly residential environment'. The method of this study was research review and questionnaire survey research. Questionnaire surveys were conducted with the housewives at the two subject apartments in Busan. Based on tools to assess pedestrian environment, this study analyzed correlation between health-related satisfaction with residential environment and satisfaction with pedestrian environment. Satisfactions with pedestrian environment showed a strongly positive (+) correlation with contentment with health-related residential environment Second, this study analyzed residents' use, demands, and satisfaction for pedestrian environment. More active pedestrian environment are required (i.e. a trail or sports facilities) to create residential environment which could support the enhancement of physical health To perform the mean comparative analysis and correlation analysis of the survey results, PASW 18.0 was used.

Background: A common genetic variant rs3757318, located in intron of C6orf97, was firstly identified to be associated with breast cancer (BC) risk by a genome-wide association (GWA) study. However, subsequent validation studies with different ethnicities have yielded conflicting results. Materials and Methods: We performed a meta-analysis to synthesize all available data for evaluating the precise effect of this variant on BC susceptibility. Results: A total of 8 articles containing 11 studies with 62,891 cases and 65,635 controls were included in this meta-analysis. When compared to the G allele, the rs3757318-A allele was significantly associated with BC risk with the pooled OR of 1.21 (95% CI=1.15 - 1.29, P<0.001) but with obvious between-study heterogeneity (P=0.040). Stratified analysis suggested that diversity of ethnicity along with control source may explain part of the heterogeneity. Similarly, significant associations were also identified in heterozygote, homozygote, dominant and recessive genetic models. Sensitivity and publication bias analyses indicated robust stability of our results. Conclusions: Our present meta-analysis demonstrated that the variant rs3757318 is associated with increased BC risk. Nevertheless, further studies are needed to clarify the underlying biological mechanisms.

Inorganic acids such as HCl, HNO₃, and H₂SO₄ have been commonly applied to soil washing of heavy metals-contaminated soil due to their cost-effectiveness. However, implementing the 'Chemical Substance Control Act' requires off-site risk assessment of the chemicals used in the soil washing. Therefore, in this study, organic acids or Fe(III)-based washing agents were evaluated to replace commonly used inorganic acids. Ferric removed heavy metals via H⁺ generated by hydrolysis, which is similar to the HCl used in the control group. Oxalic acid and citric acid were effective to remove Cu, Zn, and Cd from soil. Organic acids could not remove Pb because they could form Pb-organic acid complexes with low solubility. Furthermore, Pb could be adsorbed onto the iron-organic acid complex on the soil surface. Ferric could remove exchangeable-carbonate, Fe-Mn hydroxide, and organic matter and sulfides bound heavy metals (F1, F2, and F3). Organic acids could remove the exchangeable-carbonate and Fe-Mn hydroxide bound metals (F1&F2). Therefore, this research shows that the fractionation of heavy metals in the soil and the properties of washing agents should be considered in the selection of agents in the process design.

The purpose of this study is to provide information on a forest healing environment using the analysis of nature volatile organic compounds (NVOCs) and thermal comfort in Chungnam National University Experimental Forest, with the aim of using the Experimental Forest as a healing environment for health promotion. We analyzed NVOCs and thermal comfort of Chungnam National University Experimental Forest measured on September 12^th, 2021. As a result of the NVOC analysis, a total of seven substances were detected, mainly including alpha pinene and beta pinene. The detection amount for each time period was highest at the time of sunset. The thermal comfort was analyzed by time-dependent changes and changes according to clothing and exercise amount. The results showed that the predicted mean vote of the experimental forest is within the range of 'slightly cool' and 'slightly warm' sensation, and thus a comfortable thermal environment could be controlled by the amount of clothing and activity. Based on the analysis, this study provides information on the healing environment of the experimental forest at Chungnam National University. It also indicates that the forest can be used as a health promotion and healing environment with thermal comfort by composing a physical activity program of appropriate intensity for each time period.
