In this study, more than 2,500 cases using TRIZ methodology for 10 years from 2006 to 2016 in S company were analyzed to identify which TRIZ tools have been used for solving field problems. In the previous studies, some attempts were made to analyze the utilization of TRIZ tools, but all of them were based on very limited surveys or cases. The results of this study show that 40 inventive principles were most used, followed by separation principles, standard solutions, trimming, modeling using little people, patterns of evolution, ARIZ and Effects. In addition, detailed analysis were performed for widely used tools such as 40 inventive principles, separation principles, standard solutions, etc. The analysis would be a useful guide for the study and application of TRIZ tools in industry.

본 연구는 공과계열 4년제 대학생, 졸업생, 인사담당자를 대상으로 NCS 직업기초능력의 중요도, 현재 자신의 수준, 교육요구를 파악하여 대학의 NCS 교육과정 개발 및 운영에 대한 시사점을 도출하는데 목적이 있다. 이를 위해 대학생 533명, 졸업생 730명, 인사담당자 106명을 대상으로 NCS 직업기초능력의 중요도 및 자신의 수준을 조사하였다. 그 결과 첫째, 인사담당자는 재학생, 졸업생에 비해 모든 역량이 중요하다고 인식하고 있었고, 졸업생은 재학생에 비해 모든 역량에 있어 현재 자신의 수준이 높다고 인식하는 것으로 나타났다. 둘째, 재학생과 졸업생은 자기개발능력, 기술능력, 문제해결능력에 대한 교육요구도가 높았고, 수리능력, 자원관리능력, 조직이해능력, 직업윤리에 대한 교육요구도가 낮게 나타났다. 반면 인사담당자는 자기개발능력, 의사소통능력, 문제해결능력에 대한 교육요구도가 높았으며, 수리능력, 자원관리능력, 정보능력, 기술능력, 조직이해능력, 직업윤리에 대한 교육요구도가 낮게 나타났다. 이러한 결과를 바탕으로 재학생 및 졸업생, 인사담당자가 인식하는 교육요구도를 종합적으로 고려하여 NCS 교육과정을 개발 적용할 필요가 있다.

The purpose of this study is to provide basic data and guideline to STEM(Science, Technology, Engineering, Mathematics) educators who prepare engineering education in elementary and secondary school. For this, this study develops a composition model for engineering education program of elementary and secondary school. To do this, a literature research, experts interview and Delphi survey were conducted. Through the literature research, we extracted the components of model for engineering education program of elementary and secondary school and then made a first draft of the model. The draft was revised by experts while Delphi survey was used to validate the model based on Delphi panels' opinions. The panels for the Delphi survey consisted of 51 experts in the STEM education field. The survey was conducted three different times and importance survey was included in the third stage. The conclusions of this study were as follows: First, the model consist of definition, 4 directions, 4 characteristics, 3 educational goals according to school level, educational contents area and element, teaching and learning method and evaluation method. The educational contents area and element consist of 2 major areas, 7 areas and 18 elements. Second, all components of the developed model were valid in most of the statistics such as mean, standard deviation, the degree of consensus and convergence, and CVR(Content Validity Ratio). Third, importance for education contents area and element according to the school level are analyzed.

The purpose of this study was to analyze the current status of team learning in engineering education. For this, literature review and survey were used. The survey was conducted with 16 professors and 627 students in engineering college. Based on the results, team should be organized in consideration of various characteristics and competencies for effective team learning activities in engineering education. And in the team learning operations, it is necessary to make the conditions for students to immerse in team learning through the activation of communication of team members, tightening management of free riding in team learning, and optimizing team learning period. It is necessary to use the team learning evaluation method in harmony with the team, individual and peer evaluation.

The purpose of this study is to analyze the current evaluation methods on faculty performance at Korean engineering colleges and develop teaching evaluation indicators for faculty performance. We investigated the faculty performance cases in engineering colleges inside and outside of the Korea, the engineering faculty's awareness of evaluation factors for their educational performance, and the appropriate ratios by indicating factors. Also we developed evaluation indicators for educational achievements to improve the current faculty performance system. 227 engineering faculty members answered our survey questionnaire. The result in the case study on faculty performance evaluation is as follows. First, most items of faculty performance evaluation are about quantitative indicators that can easily conduct objective evaluation. Second, evaluation items of faculty performance are mostly focused on instruction in a classroom. Third, the evaluation by students and administrative managers is more dominant than that by professors or their colleagues, document evaluation than on site evaluation, general evaluation than formative evaluation, and static evaluation than dynamic evaluation. Lastly, Some universities tend to substitute outstanding articles for underperforming instruction. The evaluation indicators that we have developed can be implemented by four types of subjects, such as students, professors, their colleagues, and deans. Also, based on the evaluation indicators, faculties can freely select their evaluation domains depending on the their tracks, such as a teaching track, a research track, or an industry-university cooperation track. The mandatory evaluation fields include teaching, student counselling, teaching portfolio evaluation by mentors or colleagues, class management evaluation by deans, and self-evaluation. The other areas are optional and professors can choose their evaluation factors.

The purpose of this research is to analyze the educational experiences of competent engineering students and finding the reason why they invest their time and efforts engaging in school activities. Five students with high GPA, high K-CESA scores and successful employment or entrance test scores, participated in the survey and the interview. In checking their responses, their activities' records were gathered from school DB. According to the modified framework based on the personal investment theory, the interviews, survey and DB records were analyzed on the sense of self, the social cultural environment, and pattern of behaviors in schools. The competent engineering students are able to manage themselves, in maintaining a good relationship with the collegiate, and in having high self-efficiency. They also tend to put effort into their studies and participate in inbound and outbound school activities. At the last part, freshmen foundation, relationship within college, students' activity related future career, economic stability during studies are suggested for supporting students in universities.

Automatic flow control system composed by hardware and software was designed and fabricated to be used as teaching tool of feedback control theory in university experimental class. This system includes hardwares like data acquisition board, flow measuring device, transmitters, and the pneumatic valve, and software like LabView program for the monitoring and control of flow rates. The system was designed as the student can see the control effect of not only set point but also disturbance changes. Also the LabView program was composed for the calculation of controller parameters of both Ziegler-Nichols and Cohen-Coon tuning. The students can apply both tuning constants and compare the control performances. This system will provide the easy way for the students to understand the function and specification of control hardwares, and to raise the programing ability of control software.

It was only 2010 when start-up education spread to undergraduate education in South Korea. Start-up education was conducted so late that there are insufficient studies of evaluation and feedback on the effectiveness of start-up education. Education is a complex concept of teaching people in a desirable direction and developing their inherent abilities. Based on this, start-up education can be defined as cultivating students' entrepreneurial spirit internally and making them exhibit start-up competence externally by teaching them the knowledge, skills and attitudes necessary for business start-up and developing abilities such as creativity, challenge spirit and problem-solving skills. This study conducted pre and post survey to check if the education camp for the technology start-up, which is a practice-oriented start-up education, has an effect on the change of the participating students' perceptions about the business start-up. This study would analyze various factors of college students' business start-up through a factorial analysis so that the quantitative accumulation of start-up education can lead to a qualitative change and propose measures for the management of the quality of the education.
