Objectives: To ascertain whether some result of hematological examination could be as reference data for health management of welders. Method: The authors conducted the hematological examination of 1,018 welders and 531 control workers of a shipbuilding industry in Ulsan using automatic blood analyzer. Results: The WBC count of welders was lower than that of control on controlling the age and the duration of employment, but changes of other blood cells were not observed. Conclusion: We could use the results of hematological examination such as WBC counts as an indicator for subtle changes of health status of welders.

Increasing competition in the livestock industry has forced producers to cut costs by adopting new technologies aimed out increasing production efficiency. Non-ruminant livestock do not express fibrolytic enzymes. The major plant cell wall components of cereals, primarily β-glucans and arabinoxylans, form gel-like structures in the small intestines that trap nutrients. The viscous polysaccharides can also cause severe gastrointestinal disorders. (omitted)

This study investigated how much EVA which evaluate firm's value can explain hospital bankruptcy prediction as a explanatory variable including financial indicators in Korea. In this study, artificial neural network and logit regression which are traditional statistical were used as the model for bankruptcy prediction. Data used in this study were financial and economic value added indicators of 34 bankrupt and -:4 non-bankrupt hospitals from the Database of Korean Health Industry Development Institute. The main results of this study were as follows: First, there was a significant difference between the financial variable model including EVA and the financial variable model excluding EVA in pre-bankruptcy analysis. Second, EVA could forecast bankruptcy hospitals up to 83% by the logistic analysis. Third, the EVA model outperformed the financial model in terms of the predictive power of hospital bankruptcy. Fourth, The predictive power of neural network model of hospital bankruptcy was more powerful than the legit model. After all the result of this study will be useful to future study on EVA to evaluate bankruptcy hospitals forecast.

This study was designed to evaluate the gastroprotective activity of cirsilineol in hydrochloric acid (HCl)/ethanol-induced gastric ulcer model. Cirsilineol was administered at the doses of 20 and 40 mg/kg in HCl/ethanol-induced rats. The gastroprotective ability was verified by determining the ulcer score, total acidity, hemoglobin, inflammatory cytokines, lipid peroxides, and enzymatic antioxidants superoxide dismutase (SOD) and catalase (CAT) in gastric tissue and serum biochemical analysis. The results showed a favorable increase in the hemoglobin level, antioxidant enzymes (SOD and CAT), restored electrochemical balance (carbon dioxide & anion gap) while a noticeable decrease in ulcer index, total acidity, lipid peroxides, inflammatory cytokines (interleukin-1 beta [IL-1β], IL-6, and tumor necrosis factor alpha) in rats treated with the cirsilineol. The serum biochemical analysis on liver markers (alkaline phosphatases, alanine aminotransferase, and aspartate aminotransferase), kidney markers (urea, creatinine, albumin, globulin, total protein), and lipid profile (triglyceride, high-density lipoprotein, total cholesterol) were attenuated by cirsilineol treatment in rats. Histopathology showed enhanced gastric protection and preserved the integrity of gastric mucosa upon cirsilineol administration. These results ultimately suggest that cirsilineol has gastroprotective effects that prevent the development of gastric ulcer.

The objectives of this study were first to inspect the background information of an incentive pay system in hospitals, which provide specialized services for the public, the current status of hospitals with the system, as well as effects produced by introducing it, and then to come up with measures to invigorate the system. According to the findings of a survey, a total of 123 out of 150 hospitals responded that they applied the system to their HR management, some fully or some partially, which accounts for 82.0 percent. This study suggested that the following strategies to invigorate the incentive pay system: having a clear objective when adopting the system; concerted performance targets; practical yet worth challenging business objectives; transparent information disclosure; and establishing a confidence-building system between labor and management. Mutual trust between labor and capital should be a key factor for the successful implementation of the incentive pay system.

The purpose of this study was to identify the influence of hospital nurses' communication competence on resilience. Participants were 178 nurses who were from 5 general hospitals located in Seoul, Gyeonggi-do province in Korea. The data were collected from September 5 to 19, 2021 and analyzed using t-test, ANOVA, Pearson correlation coefficient and multiple regression with SPSS/WIN 22.0 program. The average score of communication competence was 3.57 and resilience was 3.43 points. The total correlations was .68 between communication competence and resilience. Communication competence explained 50% of the total variance of resilience(ρ<.001). Communicative effectiveness(β=.24, ρ<.001), immediacy(β=.19, ρ=.01), assertiveness(β=.15, ρ=.03) and social adaptability(β=.16 ρ=.02) were the significant factors influencing on resilience of hospital nurses. The findings suggest that we need to make efforts to increase the specific factors of communication competence affecting on resilience of nurses.

Several efforts to replace the use of existing fossil energy resources have already been made around the world. As a result, a new industry of renewable energy has been created, and efficient energy distribution and storage has been promoted intensively. Among the newly explored renewable energy sources, the most widely used one is solar energy generation, which has a high market potential. An energy storage system (ESS) is a system as required. In this paper, the design and implementation of an ESS for the efficient use of power in stand-alone street lights is presented. In current ESS applied to stand-alone street lights, either 12V~24V DC (from solar power) or 110V~220V AC (from commercial power) is used to recharge power in systems with lithium batteries. In this study, an ESS that can support both solar power and commercial power was designed and implemented; it can also perform emergency recharge of portable devices from solar powered street lights. This system can maximize the scalability of ESSes using lithium batteries with efficient energy conversion, with the advantage of being an eco-friendly technology. In a ripple effect, it can also be applied to smart grids, electric vehicles, and new, renewable storage markets where energy storage technology is required.

The current hospital industry is showing relatively low profitability in comparison with other industries due to the low medical fees and high costs. Therefore, our government presented the direction of improvement through model execution and support of the specialized hospitals. However, it is estimated that the specialized hospitals also will show differentiated management performances in accordance with their specialized fields due to the characteristics of medical treatment. Therefore, this study had attempted an analysis on the financial index in accordance with the weight of medical treatment items for the rehabilitative medicine department among the whole hospital groups through getting out of analyzing financial indices of individual hospitals centered at their costs. For this p개pose, this study had carried out its research by partially reciting the study on the plan for utilizing participations of private health resources to expand rehabilitative medicine services into the private people of the Korea Health Industry Development Institute(KHIDI). As its results, it was shown that the stability, profitability, activity and productivity of hospitals with high weight of medical treatment for the rehabilitative medicine department were lower than those for the general hospitals. To support smooth operations of these hospitals 'with high weight of medical treatment for the rehabilitative medicine department or of specialized rehabilitation hospitals, it is judged that the plan such as the support for hospital management fund and the additional recognition on the rehabilitative fees, etc. together with the actualization of medical fees must be provided for the institutions which are providing rehabilitative medical services more than the fixed percentage and being equipped with the sufficient medical equipment and personnel to do them.
