In this study, It is utilized 103 management panic data about social enterprises in Chungnam area (Chungnam, Daejeon, Sejong) region from 2011 to 2017. The organizational characteristics (organizational type, type of certification, company's region, external grants, paid employees) were set as independent variables with economic performance (sales) and social performance (employment of vulnerable class) as dependent variables. We analyzed the factors affecting the economic and social performance of social enterprises and confirmed the correlation between economic and social performance. The results of this study are as follows: First, the organizational characteristics of social enterprises showed a significant difference in sales as economic performance. External grants have no positive effect on the economic performance (sales) of social enterprises, while paid workers have a positive (+) influence on the economic performance. Second, the organizational characteristics of social enterprises showed significant differences in employment of the vulnerable class, which is social performance. Only the paid workers had a statistically significant relationship with the social performance of the social enterprise. Third, the correlation between economic performance (sales) and social performance (employment of the vulnerable class), which is the result of social enterprise, is shown. This can enhance a social enterprises' sustainable growth and self-sufficiency by improving the employment of vulnerable people, the economic performance of a social enterprise, which is sales and social performance, and ultimately can manifest the value and purpose of the social enterprise.

본 연구는 인형연행의 역사를 기술하는 새로운 모색의 일환으로 자리한다. 일반적인 문화사적 전개에 의존하는 방식이나 왕조별 접근의 방식, 나아가 이 둘의 결합된 방식을 넘어서서 또 하나의 새로운 방식을 시도한 것이다. 여기에는 인형연행의 '역사'가 아니라 '인형연행'의 역사를 기술하려는 필자의 지향이 함축되어 있다. 이를 위하여 필자는 조선 시대까지의 인형연행 관련 자료를 대상으로 논의를 했다. 이 자료에는 문헌 자료는 물론이고 유물, 그리고 그림까지 포함된다. 논의는 우선 인형연행의 자료를 정리하고 분류 기준을 설정하는 것으로 시작되었다. 50항목에 이르는 자료들을 정리하고, 이를 분류할 기준을 설정하였다. 분류 기준은 1차적으로 인형연행이 자리하는 문맥이 설정되었다. 이는 제의와 오락으로 나타난다. 2차적 분류 기준은 인형연행의 핵심적 사항인 연행방식이다. 이 기준에 따라 조종, 목소리연기, 섬김, 축출, 진열 등의 항목이 설정되었다. 이러한 분류 기준에 따라 인형연행을 유형화하고 시대를 구분하는 논의가 이어졌다. 그 결과 인형연행의 시대는 '다양한 인형 이용의 시대', '섬김의 제의적 인형연행 시대', '조종의 오락적 인형연행 시대', '진열의 제의적 인형연행 시대', '축출의 제의적 인형연행 시대', '조종의 제의적 인형연행 시대', '진열의 오락적 인형연행 시대', '조종과 목소리연기의 오락적 인형연행 시대' 등으로 구분되었다. 이러한 인형연행의 내적 시대 구분에 따라 이를 통시적으로 펼쳐 보이는 인형연행사 기술이 이어서 이루어졌다. 그 기술의 결과, 인형연행은 왕조사적 시대 구분에 메이지 않고 나름의 전개 과정을 보이고 있음을 확인할 수 있었다. 그리고 '정적인형에서 동적인형으로'나 '제의적 연행에서 오락적 연행으로'라는 일반적인 문화사적 전개와는 다른 양상을 보이고 있음도 확인되었다. '무언인형에서 유언인형으로의 전개'를 제외하고는 일반적으로 받아들여지는 인형연행의 문화사적 전개와는 다른 양상을 보였다. '제의적 인형연행에서 오락적 인형연행으로의 전환'이라는 전개과정은, '제의적 인형연행과 오락적 인형연행의 순환'으로 수정되어야 하는 양상이 나타났다. '정적 인형에서 동적 인형으로'라는 전개과정 역시 '정적 인형과 동적 인형의 순환'이라는 차원에서 바라보는 것이 보다 적절한 것으로 판단되었다. 이렇게 일방적인 전환이 아니라 순환으로 나타나는 이면에 자리하고 있는 것은, 인형연행이 한 시대를 마감하게 되었다고 그 시대의 인형연행이 그 전승을 마감하는 것이 아니라는 점이다. 한 시대에서 다른 시대로 인형연행이 전개되는 동시에 이전 시대의 인형연행은 그 나름의 자체적 생명력을 가지고 지속과 변화의 모습을 보였다. 또한 크게는 제의적 인형연행과 오락적 인형연행 사이에, 작게는 각각의 인형연행 유형 사이에 상호영향 관계가 존재한다는 점 역시 인형연행의 역사를 살피는 데 있어 간과해서는 안 될 사항으로 제기되었다. 본 연구를 통해 이루어진 인형연행사의 새로운 모색과 기술은 완결된 것이 아니다. 그야말로 '또 하나'의 인형연행사 기술의 시도였을 따름이다. 이 시도는 인형연행 외부에 자리한 정치·경제·사회적 문맥을 전혀 고려하지 않고 있다. 또한 대단히 조심스러운 태도를 보이고 있지만, 인형연행 전통의 지속을 염두에 둔 기술이었음을 부인하지 못한다. 인형연행 외부 문맥을 감안하고, 지속이 아닌 단절까지 감안하는 인형연행의 문화사 기술이 시도될 필요가 있다. 또한 인형연행사를 넘어서는 다른 전통연행까지 포괄하는 전통연행사를 장기적으로 염두에 두는 포석도 필요하다. 이러한 과정에서 본고에서의 제안이 비판적으로 검토되기를 필자는 기대한다.

In this study, an in-house program to analyze the performance degradation for gas turbines is developed using MATLAB and is validated using commercial software. This program consists of design and off-design calculations. The results of design calculation is used for reference values of off-design calculation. The off-design calculation is composed of measured and expected performance analyses, and turbine inlet temperature correction. In general, performance degradation is analyzed by comparing the results of measured and expected performance analysis. However, if gas turbine performance degrades, turbine inlet temperature might increase due to the general control logic to comply with the power demand. Therefore, it is required to consider the deviation of turbine inlet temperature from the normal value in the performance diagnosis to analyze the performance degradation exactly. In this study, a special effort is given to the correction of turbine inlet temperature. The accuracy of the developed program is confirmed by comparison with commercial software, and its capability of performance diagnosis using the turbine inlet temperature correction is demonstrated.

Many enterprises are interested in using the IS development methodologies as a means of increasing system performance and solving the problems of delayed delivery time, excessive budget, and failure of integrated systems. Even if previous researches showed that the system productivity and quality improvement using the system development methodologies are very poor, we tried to find that the methodologies are meaningful as an innovative means for IS performance. We defined that the IS development methodology as a technical and managerial innovation for IS department. We intended to study the relationship between the implementation process of the IS development methodology divided into four steps and IS performance. A cross-sectional field survey with IS departments of domestic companies was conducted, and we used LISREL 8.12a to perform the structural equation model analysis and hypothesis verification. We found the meaningful relationship between the development methodology and qualitative performance. We reconfirmed that the relationship between the development methodology and quantitative performance is not meaningful as expected, which is the same result with the previous researches. But the qualitative performance affects very strongly to the quantitative performance. As a results, we suggest that IS managers and developers keep the principles of the IS development methodologies to get the quantitative performance through the qualitative performance improvement.

Split magnetic fluid sealing is a combination of magnetic fluid rotary and plane sealing. Using the theory of equivalent magnetic circuit design as basis, the author theorized the pressure resistance performance of magnetic fluid plane sealing. To determine the pressure resistance of magnetic fluid plane sealing, the author adopted the method of finite element analysis to calculate the magnetic field intensity in the gap between plane sealing structures. The author also analyzed the effect of different sealing gaps, as well as different ratios between the sealing gap and tooth and solt width, on the sealing performance of split magnetic fluid. Results showed that the wider the sealing gap, the lower the sealing performance. Tooth width strongly affects sealing performance; the sealing performance is best when the ratio between tooth width and sealing gap is 2, whereas the sealing performance is poor when the ratio is over 8. The sealing performance is best when the ratio between the solt width and sealing gap is 4, indicating a slight effect on sealing performance when the ratio between the solt width and sealing gap is higher. Theoretical analysis and simulation results provide reference for the performance evaluation of different sealing equipment and estimation of critical pressure at interface failure.

At present, in the case of pump fast optimization, there is a problem of rapid, accurate and effective prediction of cavitation performance. In "A Cavitation Performance Prediction Method for Pumps PART1-Proposal and Feasibility" [1], a new cavitation performance prediction method is proposed, and the feasibility of this method is demonstrated in combination with experiments of a mixed flow pump. However, whether this method is applicable to vane pumps with different specific speeds and whether the prediction results of this method are accurate is still worthy of further study. Combined with the experimental results, the research evaluates the sensitivity and accuracy at different flow rates. For a certain operating condition, the method has better sensitivity to different flow rates. This is suitable for multi-parameter multi-objective optimization of pump impeller. For the test mixed flow pump, the method is more accurate when the area ratios are 13.718% and 13.826%. The cavitation vortex flow is obtained through high-speed camera, and the correlation between cavitation flow structure and cavitation performance is established to provide more scientific support for cavitation performance prediction. The method is not only suitable for cavitation performance prediction of the mixed flow pump, but also can be expanded to cavitation performance prediction of blade type hydraulic machinery, which will solve the problem of rapid prediction of hydraulic machinery cavitation performance.

The purpose of this research is to investigate the mediating role of performance information use in the relationship between result-oriented culture and organizational performance. The data were collected from chief accountants and managers working in public-sector organizations in Vietnam. The analysis was based on the 197 completed questionnaires by using Partial Least Squares Structural Equation Modeling (PLS-SEM). For the test research model and hypotheses, the supporting tool is SmartPLS 3 software. Research findings show that result-oriented culture is positively associated with organizational performance, and that performance information use is a mediating mechanism that explains how a result-oriented culture leads to higher performance in public organizations. The findings of this study suggest that the results-oriented culture, not only directly improves organizational performance, but also indirectly does so by the use of performance information. This study provides evidence for theoretical understanding of the impact of result-oriented culture on the performance of public-sector organizations through performance information use, and suggests practical implications for public organizations in applying result-oriented culture to foster using performance measurement and improve organizational performance. In order to achieve good performance, public-sector organizations need to create and spread result-oriented culture and enhance the use of performance information for decision-making.
