최근 수요가 급증한 36W 단일 캡 형광램프의 과열로 인하여 화재의 위험성이 대두되고 있다. 단일 캡 형광램프는 이중 캡에 형광램프에 비하여 길이가 작아 다루기가 쉽고, 관 지름이 작아 고효율의 형광램프로 인식되고 있다. 그러나 한쪽방향에 전극을 가지고 있어 열 분산 면에서 이중 캡에 비하여 열 축적 가능성이 크고, 수명말기에 전극필라멘트가 열에 의해 소실되었을 경우 관경이 작아 필라멘트 지지 스템(stem)의 길이가 가까워 고속스위칭의 전자식안정기를 적용한 시스템에서 완전히 개방되지 않고 임피던스의 상승만을 가져올 수 있다. 이로 인하여 캡의 열화에 의한 분리가 일어나고, 화재의 원인이 될 수 있다. 이러한 현상은 형광등의 수명 말기에 발생하는데 본 논문에서는 형광등의 수명말기 현상을 모델링하여 단일 캡 36W 형광램프의 수명 말기에 발생하는 과열에 관한 시험방법에 대하여 시험 연구 하였다.

The load deformation behavior of the cap-pile-soil system is investigated, based on numerical analysis. Special attention is given to consideration of pile cap flexibility. Rigid pile cap analysis and flexible cap analysis were conducted for comparison. A numerical method that takes into account the coupling between the rigidities of the piles, the cap, and the column has been introduced to analyze the response of pile group supported columns. The prediction of the lateral loads and bending moments in the pile cap is much more conservative for a flexible cap than for a rigid cap.

This case study analyzed the effect of capstone design on students' competence and class satisfaction. Three subjects developed in S university were analyzed, and 92 students participated. Results show that the lesson structure of the capstone design was developed to provide students with problem solving competence and practical business skills through hands-on experience. In addition, the students' competence was enhanced, and their satisfaction in class was very high. Statistical results show that, compared to the existing classes, class satisfaction in capstone design improved significantly. Considering the foregoing results, this study suggested that for the capstone design, the lesson structure and method need to be diversified to provide more opportunities for students to participate and become active. The assessment procedure and method also have to be more objective to lessen subjectivity and to increase class satisfaction in capstone design.

A pile group, that consists of several piles connected by a pile cap, is used as the superstructure. The pile supports vertical and horizontal load to design the pile group, but the effect of bearing capacity of the pile cap has not considered. Various researches have been conducted to reflect the effect of bearing capacity of the pile cap in order to reduce the amount of piles in the range of the stability under the vertical load of the superstructure. However, the effect of bearing capacity under the horizontal seismic load has not been studied adequately. Therefore, a shaking table test was carried out with different-sized pile caps that support the superstructure in this study. This test was to verify the influence of the size of the pile cap in the group pile under the horizontal load. The result shows that the size of the pile cap affects to the dynamic behavior of the superstructure and the pile group. Also, the bigger size of the pile group makes the larger constraint effect of ground, and it results that both the ground and the pile moves as a whole.

In this study, the case of capstone design course operation for the execution of SW development-oriented projects in the field of computer engineering is presented, and a 3-tier capstone design model is proposed through the case. Recently, most engineering departments operate capstone design classes, but in many cases, capstone design courses are generally operated in the graduation year. Students taking these capstone design courses are experiencing difficulties in the process of actually coding and implementing together with the collaboration process according to the team project class operation, but before these difficulties, derivation and verification of possible ideas and concrete ideas It is showing more difficulties in the process. In this study, in order to efficiently operate the capstone design and create results, in the second semester prior to graduation, students, professors, and mentors from industry mentors will work together to develop ideas through an idea tone contest, etc. Through the second semester, we propose a 3-tier capstone design model that can advance the idea and actual implementation and implementation of the derived ideas.

In this paper, we introduce a model of the teaching and learning method for multidisciplinary convergence capstone design at Kongju National University's Engineering Department. At Kongju national University, various capstone design works are designed and proceeded by multidisciplinary students at the summer session. The multidisciplinary approach described in this paper includes the involvement of five department's student who have not collaborated in capstone design experience. This study focuses on multidisciplinary capstone design education by using the micro controller board called Arduino Uno that consists of an assortment of sensors and actuators. The result of self-satisfaction survey was shown the meaningful teaching process for the engineering department students who could have more creative and industrial experiences. As a result, we are able to get the result of the possible directions for future technology education in the area of convergence multidisciplinary capstone design.

Capstone design course in current domestic software education environment has been opened in undergraduate courses in order to improve student's practical skills. However, the capstone design course is hardly applied the software convergence trend. We opened the capstone design course in not only the students in certain department, but also the students in other departments in order to solve this problem, and then we analyzed the operating results of this capstone design course. In the analyzed result, we find that operation of the convergence capstone design course is enough satisfactory, but we find that the operation of the convergence capstone design course has the limit that the certain department operates individually the convergence capstone design project. Hence, we need that the convergence capstone design course is preferably operated as the department-integration.

The purpose of this study was to comprehensively examine the effect of capstone design education on learning outcomes and propose directions for effective design and implementation of capstone design classes. For achieving this, a 21 studies meeting the standards among the academic journals and thesis published in Korea by September 2020 were selected, and based on 83 effect sizes, the meta analyses were carried out. The results of this study were as follows: First, the total effect size of capstone design education was 0.96, which is a large effect size. Second, the effect size was large in order of affective, cognitive, and social areas. Third, the effect size of vocational basic ability showed a large effect size while creativity showed a medium-sized one. Fourth, the effect size showed highest for design subject, the grade in the third or fourth, there was help from industrial corporation, theory and practice. Based on these results, this study proposed instructional design implications in order to increase the learning effects of capstone design in Korea.

This paper introduces a case study on the development of the evaluation system for capstone design course which is usually provided at engineering education program. A capstone design is an engineering education course which aims to improve the students' ability on analysis and design of practical industrial problems by use of overall engineering knowledge which has been learned in undergraduate program. Firstly, this paper provides a literature review on evaluation indices and methods related with a capstone design course. Secondly, the evaluation system for learning outcomes of capstone design course is described. The evaluation system for learning outcomes of capstone design course provided in this paper could be referred by other universities opening a capstone design course, and used to design an evaluation system for internship program or education course which is provided as an industry-academic connection program.
