본 연구는 대학의 학부 학생들에게 자율적인 연구 기회를 제공하기 위하여 운영하고 있는 학생연구프로그램의 성과를 점검하고 교육적 효과를 분석하기 위하여 수행되었다. 학생연구프로그램은 학생이 주도적으로 자율적이고 책임 있는 학습을 할 수 있는 기회를 제공하고 이를 대학의 교과과정을 개선하기 위한 목적으로 개발되었다. 본 연구는 서울대학교가 2003학년도부터 2009학년도까지 83명의 학부생을 참여시켜 수행한 프로그램의 성과를 평가하기 위하여 참여자들을 대상으로 설문조사와 심층 면담을 실시한 결과들이다. 참여자들은 본 프로그램에 참여하면서 자율적 탐구 능력 및 문제해결 능력의 함양, 학문 영역을 넘어선 다양한 전공의 경험, 진로 선택에 영향을 받았다고 응답하였다. 이와 같은 결과는 대학에서 교육 개선을 위한 새로운 교과과정의 틀을 마련하는 데 기초 자료로 활용될 수 있을 것이다.

Internet of things (IoT) is based on a global dynamic information network with cloud services where a great number of devices (things) exchange data to provide added-value services and products. There are several commercial and open source IoT platforms available in the market to connect devices to internet; however, they have cost and operational constraints that make them not suitable for academic projects. In this work, an IoT platform, known as Novus-io, is introduced in order to support academic projects for undergraduate students. With this platform and proper training, undergraduate students from different majors (not only from information technology and electronics) are capable to upgrade their school projects with IoT functionalities. The objective of this approach is to provide to any undergraduate student skills and knowledge on IoT, so they will be prepared, in their imminent step toward professionalism, to understand the relevance of digital services in today's world.

In electrolysis smelting plants that using high DC current, the bus bar is most important facility for delivering the high current. The copper made bus bar is widely used for various advantages as good electrical and thermal conductivity, resonable malleability, ductility, and not rust easily. However, when high current in copper bus bar, temperature rises and maximum allowable current capacity is restricted by temperature of bus bar. In this paper, we investigated temperature variation of copper bus bar by putting cooling water channel imposed to bus bar construction. For the validity, various simulations were carried out.

The purpose of this study is to propose a strategy model for engineering education for citizen through the connection between colleges of science and engineering and science museums as a way to achieve citizen science. For this model, the role of universities was redefined as social contributions through engineering education from the perspective of knowledge triangle and university entrepreneurship. In addition, the science museum was re-examined as an engineering education platform and selected as an institution that supports the contribution of colleges to society. For practical model development, the connection types of these two institutions were analyzed as case studies and interview to collect opinions from experts in the science museum. In this process, convergence education content development, reinforcement of college-science museum linkage, infrastructure construction, development of college resource utilization plans, and maintenance and expansion of educational programs diversification were derived as components for model development. Based on this, engineering education model for citizen was presented that matches educational programs according to the type of participation of colleges including key factors and considerations.

This study starts from the perspective that preparing students for employment is the most important role of undergraduate degree programs. Therefore, we examine the determinants of undergraduate employment, especially highlighting the differences by disciplines. We classify 28 factors into five categories such as personal attributes, entrance attributes, students’ employment-related activities, regular curriculum and employability programs provided by universities. This study is based on data from 7,616 students from a Korean university over four and half years. Findings reveal that university efforts are crucial in engineering. Only exchange programs and employment programs have an impact on science. There are no specific factors in humanities and social science. Grade point average and students’ efforts are important in business. Face-to-face coaching in employability support programs is effective for securing employment except in science disciplines. The study results do not point to the absence of a role of university even in the low employment disciplines. Rather, the issue is that of an over-supply of graduates exceeding job offers that results from the worldwide expansion of higher education services.

Almost all injection molds have multi-cavity runner system for mass production, which are designed with geometrically balanced runner system in order to accomplish filling balance between cavity to cavity during processing; However, even though geometrically balanced runner is used, filling imbalances have been observed. In these day, the CAE has been used widely in injection molding. However, CAE with fusion mesh can't indicate such as jetting, flow mark and filling imbalance in multi cavity mold. In this study, we investigated the filling imbalance according to runner shapes by CAE analysis. As a result in CAE, in case of binary branch runner system, filling imbalance was indicated between cavity to cavity, but the flow pattern of each cavity uniformed in unary branch runner system.

This research aims to examine the relationship between major satisfaction and psychological well-being of female engineering students. To achieve this goal, first, differences in major satisfaction and psychological well-being among engineering students were examined. Second, differences in major satisfaction and psychological well-being among female undergraduate students were investigated. In addition, the effects of psychological well-being, as perceived by undergraduate students by gender and major, on major satisfaction were explored. A total of three hundred and forty-nine (349) undergraduate students from two universities in Korea responded to survey based on a two-variables scale. The findings were that, firstly, male engineering students scored higher in two variables including their most sub-factors, and that gender differences in relation satisfaction as well as positive relationship with others, autonomy, and environmental mastery were statistically significant. Secondly, female engineering students scored higher in major satisfaction and several sub-factors of two variables, and that major differences in major satisfaction (total), social perception satisfaction, and autonomy - a sub-factor of psychological well-being - were statistically significant. Thirdly, a positive correlation among major satisfaction and psychological well-being was identified. Finally, psychological well-being could explain about 19% of major satisfaction. The practical implications of these findings are discussed herein, with attention on education for promotion of major satisfaction.

Now days CAE has been used for almost all injection molding designs in order to find the best injection conditions. Almost all CAE use 2-D mesh, but the CAE with 2-D mesh can't indicate such as jetting, flow-mark and filling imbalance in multi cavity mold. In this study, we suggested a new 3D meshing. the method which can indicate the filling imbalance in geometrically balanced runner system with Mold Flow MPI 6.1 and we found out that the calculation times are saved. As a feasibility study, we verified that Melt Flipper, RC Pin etc appeared the balanced filling behaviors. of geometrically balanced runner system and Melt Flipper, filling imbalance was indicated more accurately.
