The performance of supersonic impulse turbine was investigated experimentally. Experiment was performed with the compressed air instead of the high temperature burned gas because of the limitation of test facility and danger. As a result of the experiment with the compressed air, the performance in the real gas(burned gas) was predicted by the similarity method. The nozzle area of prototype turbine was calculated based on the real gas. So, it is difficult to satisfy the similarity conditions completely. Two similarity conditions were set and the design point for real gas was existed between two similarity conditions. And, the new turbine test model with calculated nozzle area based on the compressed air was tested. Therefore, similarity point of the new turbine test model was also existed between above two similarity points. It means that the design point for real gas was similar to the test point with the new turbine model.

"한국사상사대계"는 우리 사상의 발달과 전개과정을 체계적으로 보여주는 데는 다소 미흡한 '방대한 논문모음'이라는 일각의 비판에도 불구하고 학제간의 공동연구의 산물이라는 점에서, 거시적 안목에서 한민족의 정신문화를 조감할 수 있게 했다는 점에서 상당한 의의를 가진다고 학계에서 평가되고 있다.

The purpose of this study is to verify trust in supervisor, customer badness behavior have turnover intention influence on job embeddedness. Self-report questionnaire was completed by 188 clinical nurse May 1st to May 30th, 2016. and date analyzed using the IBM SPSS/WIN 21.0 program. As a result, The mean score of trust in supervisor is 3.20 points, customer badness behavior is 2.66 points, job embeddedness is 3.05 points, turnover intention is 3.39 points(out of 5). There were significant positive correlations between job embeddedness and trust in supervisor(r=.57, p<.001) and turnover intention(r=.19, p=.011) and negative correlations between Sacrifice sub-cale of job embeddedness and customer badness behavior(r=-.15, p=.037). The convergence factors with the effect on job embeddedness, trust in supervisor(${\beta}=.471$, p<.001), job satisfaction(${\beta}=.226$, p<.001), turnover intention(${\beta}=-.196$, p<.001), nursing satisfaction(${\beta}=-.169$, p=.005) explained 48.9% of the job embeddedness. therefore, nursing managers have to strategy increasing nurse trust in supervisor and job satisfaction and nursing satisfaction for job embeddedness and plan to lower the turnover intention at the organization level.

The present study conducted in two parts toward employees in government office and state-owned companies, and financial companies. First, main impacts were demonstrated in the links between superior communication ability (SCA) and outcome variables (self-efficacy, and learning goal orientation). Second, mediating effects of self-efficacy and LGO were investigated in the relation SCA-Innovative behavior. The data which applied in analysis was collected from 318 employees who work at government office and state-owned companies, and financial companies in Jeju island. The results were as follows. First, SCA were positively associated with self-efficacy and LGO. Second, self-efficacy and LGO were fully mediated both relationships between SCA and innovative behavior. Findings were as follows. SCA is an important factor on self-efficacy and LGO. Such the results have meaningful implications in the research area of communication. The importance of self-efficacy and LGO were demonstrated when considering the both variable in the relations SCA-innovative behavior.

The purpose of this study was to evaluate effects of the confirmed of boss and the organizational effectiveness. For this, The mediating effect of psychological empowerment was verified. on the Influence of Organizational Effectiveness. the confirmed of boss (+)effected of the organizational effectivenes and verified the parameter part of psychological empowerment. Also The confirmed of boss (+)effected of a Junior staff's the job satisfaction and the organizational commitment. This results suggest that for maximization the organizational effectiveness need the confirmed of boss and the delegation of authority. The delegation of authority from boss provide autonomy and creativeity to Junior staffs. This ways suggest that make them the job satisfaction and the organizational commitment.

Due to the continuous spread of COVID-19 and the overall decline of the global economy, the business environment of Chinese SMEs is poor, the level of abusive supervision among managers of Chinese SMEs has generally risen state. First of all, the management' abusive supervision has a negative impact on the members' trust in leader. Secondly, the members' trust in leader has a negative impact on the members' knowledge hiding. However, the members' trust in leader has a positive impact on job engagement. Accordingly, this study puts forward some revelations on how to reduce the management' abusive supervision in Chinese small and medium-sized enterprises and the members' knowledge hiding, as well as how to improve the members' knowledge hiding and job engagement.

The main purpose of this study is to investigate the coordinate transformation based on two different systems between local geodetic datum(tokyo datum) and international geocentric datum(new Korea geodetic datum). For this purpose, three methods were used to determine seven parameters as follows: Bursa-Wolf model, Molodensky-Badekas model, and Veis model. Also, we adopted multiple regression equation method to convert from Tokyo datum to KTRF. We used 935 control points as a common points and applied gross error analysis for detecting the outlier among those control points. The coordinate transformation was carried out using similarity transformation applied the obtained seven parameters and the precision of transformed coordinate was evaluated about 9,917 third or forth order control points. From these results, it was found that Bursa-Wolf model and Molodensky-Badekas model are more suitable than other for the determination of transformation parameters in Korea. And, transforming accuracy using MRE is lower than other similarity transformation model.

This study analyzes the dispute settlement of between arbitration and litigation using a game theoretical approach. Many studies on arbitration have so far focused on the relevant institutions. However, there are few theoretical studies that have focused on the demand side of arbitration. The model presented here suggests conditions under which arbitration form a perfect Bayesian Nash equilibrium, provided that the players strategically choose a dispute settlement tool. Furthermore, the suggested model is used to analyze simple cases of international commercial dispute cases.

The purpose of this study is to examine the effect of supervisor humor on LMX and CWX. LMX and CWX on subordinates' job satisfaction. Additionally, we attempt to test the mediating roles of LMX and CWX on the relationships between supervisor humor and subordinates' job satisfaction. To verify the proposed hypotheses, we collected 230 data of employees in various industry. The major findings are as follows: 1) supervisor humor is positively associated with LMX and CWX. 2) LMX and CWX are positively associated with subordinates' job satisfaction. 3) LMX and CWX partially mediate the relationship between supervisor humor and subordinates' job satisfaction. We provided implications of the research results and recommendations for future research.

To trace the working point of pressure-fed rocket propulsion system, direct analogy model was suggested, by which propellant mass flow rate and combustion chamber pressure were calculated from propellant tank pressures, levels and flight acceleration. In this paper, the analysis of KSR-III flight test results was taken by example, and it can be described that working point transition tendency of pressure-fed rocket propulsion system can be calculated by this direct analogy model.
