The purpose of this study is to examine the effect of physical health on oral health in university staff and the mediating effect of stress on their relationship. As for the research method, a questionnaire survey was conducted from June 15 to June 30, 2021 for some university staff in the Seoul area. As research tools, general characteristics, somatic symptoms, oral symptoms, and perceived stress were investigated. For the analysis method, Pearson correlation analysis was used to examine the correlation between physical symptoms, stress, and oral symptoms, and regression analysis was used to verify the mediating effect. As a result, somatic symptoms, stress, and oral symptoms all showed a positive correlation. Also, somatic symptoms were found to have an effect on oral symptoms, and stress had a partially mediating effect on the relationship between somatic symptoms and oral symptoms: somatic symptoms directly affect oral symptoms, and stress directly and indirectly affects oral symptoms. In conclusion, institutional measures are needed to reduce the work stress of the university staff, and regular oral health education to promote oral health should be expanded.

Basel III (Third Basel Accord or Basel Standards) is a global, voluntary regulatory framework on bank capital adequacy, stress testing, and market liquidity risk. Basel III regulatory ratios include capital adequacy, asset soundness, and liquidity. The capital adequacy variables include BIS capital adequacy ratio, BIS tier 1 capital ratio, and tangible common equity ratio. The asset soundness variables include non-performing loan ratio and non-performing loan coverage ratio. The liquidity regulation variables include KRW liquidity coverage ratio and foreign currency liquidity coverage ratio. This study aims to investigate how capital adequacy standard affects efficiency of internet primary banks. As a result of this study, BIS capital adequacy ratio of domestic internet primary banks is lower than that of commercial banks. In order to maintain sustainable operation considering capital adequacy regulations, it is necessary to expand additional capital. In addition, the delinquency rate and non-performing loan ratio of domestic internet primary banks is gradually increasing due to the maturity of high-yield loans in 2019.

With the change of society and the rapid development of science and technology, the direction of future education and the functions of schools have changed. Also the roles and tasks of teachers are changing rapidly. As Germany entered into the 21st century, many discussions let to a consensus on the direction of future education and schooling withholding a sense of responsibility and solidarity for the education of all members of the society. As a result, standards for the training of general teachers and teachers for special education were presented. The purpose of this study is to compare the standard contents of teacher training for special education in Germany with the qualification criteria for special school, teachers in Korea, focusing on evaluation and giving as well detailed information on the examination of teachers for special school, as on basic subjects for the qualification of special school teachers for special education in Korea will be explored. As a result, the content of this study can be summarized by four items. The first one is dealing with the creation of a consciousness of solidarity and a sense of responsibility among the members of the society for the future education and the role of schools and teachers. The second item ist about including the capacity and competence of teachers in the restructuring of the school and in the minimum standards of teacher training for special education. Third, the specificity of each state (provincial and local) is considered in the content of standards for teacher training. Fourth, standards for teacher training are linked to each other, previous teacher education, trainee teacher education, and current teacher education.

The utilized coefficient of friction (UCOF) as a ratio of the shear force to the normal force on the ground during walking is used to identify the point at which slip is likely to occur. Shoe walking will change the utilized coefficient of friction by shoe design such as sole thickness and hardness, heel shape, and outsole pattern. In this study, subjects are 21 adults (10 female, 11 male, age: $25.2{\pm}2.3yrs$, height: $165.6{\pm}7.2cm$), analysis variables were walking speed, GRF, when the UCOF is maximal, and Tangent of CoP-CoM angle, and correlation analysis with the utilized friction coefficient (UCOF). As a result, First, for the shod walking the time point which UCOF is maximum about heel strike was faster and the magnitude was larger than for barefoot walking. Second, the correlation between the tangent of CoP-CoM and UCOF of right foot was higher at the left heel striking point (UCOF2_h) which occurred in the post propulsion phase than at the right heel striking point (UCOF1_h). This suggests that the right foot UCOF is related to the braking phase of left foot( which is the propulsion phase of right foot) rather than the braking phase of right foot.

Domestic hydraulic drifters till now have been developed by benchmarking products from overseas leading companies. However, they do not have excellent impact performance as they are not suitable for characteristics (large flow rate and low pressure) of Korean hydraulic drill power pack, and therefore, research on the optimum design has not made much headway. This study performs multi-objective function optimization for hydraulic drifters whose capacity has been redesigned to deal with the large flow rate, and also with the help of this function, it aims to improve impact power and reduce supply and surge pressure. A summary of the research study is as follows: First, we set goals for improving impact power, supply pressure, and surge pressure, and then perform multi-objective function optimization on them. After that, we secure the reliability of the optimized analytical model by comparing the test results of the prototype built by the optimized design with the analysis results of the analytical model. This study used SimulationX, that is the hydraulic system analysis software, and EasyDesign, which is a multi-objective function optimization program. Through this research, we have achieved the results that satisfy the goal of developing high power drifters suitable for Korean type hydraulic drills.
