The overdrive hub clutch is attached to a 6-speed automatic transmission to reduce fuel consumption by using the additional power of the engine. This paper proposes a means to minimize the load and roll-over ratio on the punch during the piercing process for the overdrive hub clutch product. Die clearance, shear angle, and friction coefficient, which can affect the load and roll-over ratio of the punch during processing, were set as the design variables. Sensitivity analysis was also conducted to determine the influence of each design variable on the punch load and roll-over ratio. As a result, shear angle, friction coefficient and die clearance were found to be sensitive to load and roll-over ratio. The punch load and roll-over ratio were set as the objective function and the equation of each design variable and objective function was derives using the Response Surface Method. Finally, the optimal value of the design variables was derived using the Response Surface Method. Application of this model to finite element analysis resulted in 22.14% improvement in the roll-over ratio of the punch load and material.

In order to secure sustainable financial resources and to attract more key supporters, today's art museums are trying to further develop individual sponsorship. The purpose of this study is to explore the direction of membership programs by considering membership as the first step for the development of individual supporters for art museums. Although it is not easy to generate substantial profits within a short period through membership, art museums can secure supporters who empathize with and participate in their mission and activities by developing individual supporters through membership. The new trends of support, which has emerged as a stream of "new philanthropy" since the 1990s, indicate that the needs and motivations of individual supporters are changing. This has great implications for the direction of the development and operation of membership programs at art museums. This study investigated the role, method, and direction of the development of individual supporters through membership by conducting a theoretical review and a case study on the membership programs and individual sponsors of art museums. In addition, the study analyzed the cases of the Cleveland Museum of Art, the Art Institute of Chicago, and the Museum of Modern Art in the United States, which have continuously attempted new approaches and improved membership programs based on a long history of membership operation and individual support, by centering on the new attributes of philanthropy, including participation and involvement, accountability, and transparency. Based on the results, implications and suggestions for Korean art museums were derived. Amid the lack of art museums' membership programs and academic research, this study has significance in exploring the direction and prerequisites for membership for the development of individual supporters.

Achievement at university is recognized in a comprehensive sense as the level of qualitative change and development that students have embodied as a result of their experience in university education. Therefore, the academic achievement of university students will be given meaning in cooperation with the historical and social demands for diverse human resources such as creativity, leadership, and global ability, but it is practically an indicator of the outcome of university education. Measurement of academic achievement by such credits involves many problems, but in particular, standardization of academic achievement by credits based on evaluation methods, contents, and university rankings is a very difficult problem. In this study, we present a model that uses machine learning techniques to predict whether or not academic achievement is excellent for D-University graduates. The variables used were analyzed using up to 96 personal information and bachelor's information such as graduation year, department number, department name, etc., but when establishing a future education course, only the data after enrollment works effectively. Therefore, the items to be analyzed are limited to the recommended ability to improve the academic achievement of the department/student. In this research, we implemented an academic achievement prediction model through analysis of core abilities that reflect the philosophy, goals, human resources image, and utilized machine learning to affect the impact of the introduction of the prediction model on academic achievement. We plan to apply the results of future research to the establishment of curriculum and student guidance conducted in the department to establish a basis for improving academic achievement.
