변화와 혁신의 가속화로 산업과 비즈니스에 대한 창의적 접근에 대한 관심이 높아지고 있으나 공공의 영향을 받는 건설산업은 상대적으로 이러한 창의적 접근에 대한 연구가 미비하다. 설계VE 역시 효율성 증대를 위한 창의적 접근에 대한 연구가 진행되고 있으나, 기법제안에 그친 경우가 많아, 실무적용 가능성에 대한 실증적 연구가 필요하다. 본 연구는 새로운 아이디어 창출 방법으로 BCC(Business Creativity Codes)사고체계를 소개하고, 이를 반영한 개선된 설계VE 아이디어 창출 프로세스를 제시하였다. 또한, 실무 종사자를 대상으로 BCC의 11가지 창의코드를 활용한 VE모델 분류실습과 설문 및 집단면접 등을 통해 BCC사고 체계의 유용성과 활용 가능성을 검증하였다.

Silo is a warehouse for storing granular materials such as grain, cement, petroleum compound and coal. When compared to other warehouses, the silo can use space efficiently. The coal silo are consists of silo, tunnel and extractor. Of these, there are not sufficient study and design data on tunnel. It depends heavily upon trial and error method by field engineers with several years of experience. Recently, silos are constructed with a large size, and tunnel becomes to be in danger of severe cracking and collapse by a huge load of coal. So it is necessary to analyze structural safety for tunnel. In this study, the problems of the tunnel are analyzed by field data, and reinforcement of structural weak area using FE analysis has been carried out to design the tunnel satisfying structural safety. From FE Analysis, the reinforced model which does not exceed the yield strength of the material has been proposed.

This paper asserts to teach engineering writing while teaching cornerstone design as well as addresses its background of the assertion. Cornerstone design course in which students study what is engineering design and what is the design process by team activities provides suitable circumstance for them to learn technical writing for solving communication problems and to produce some language artifacts. Studying the process-based writing and making use of the written artifacts in the course of engineering design process boosts design thinking for developing creative design concepts and mediates problem solving communications among design stakeholder.

Delta sash is an important part of automobile door, which has the functions of supporting and guiding seesaw of car's window, preventing dust and air from outside. In previous manufacturing process, each part of the delta sash was independently formed by tandem processes, and rubber is bonded to steel by poisonous glue. So, the previous processes, including roll forming process and toxic gases, had low production rate and high failure rate. In this study, progressive process design of the delta sash was proposed in order to increase productivity and high utilization of the materials. And instead of the poisonous glue used for adhesion of rubber in the previous tandem process, embossing and piercing processes were designed in the new guide to help the rubber to adhere well to steel. And the optimal piercing distance was designed to ensure structural safety, and prototypes were manufactured for verifying reliability of the processes.

Microdisplays based on organic light-emitting diodes (OLEDs) have a small form factor, and this can be a great advantage when applied to augmented reality and virtual reality devices. In addition, a high-resolution microdisplay of 3000 ppi or more can be achieved when applying a white OLED structure and a color filter. However, low luminance is the weakness of an OLED-based microdisplay as compared with other microdisplay technologies. By applying a tandem structure consisting of two separate emission layers, the efficiency of the OLED device is increased, and higher luminance can be achieved. The efficiency and white spectrum of the OLED device are affected by the position of the emitting layer in the tandem structure and calculated via optical simulation. Each white OLED device with optimized efficiency is fabricated according to the position of the emitting layer, and red, green, and blue spectrum and efficiency are confirmed after passing through color filters. The optimized white OLED device with color filters reaches 97.8% of the National Television Standards Committee standard.

페리다이나믹스 이론과 이진분해 기법의 병렬연산을 이용하여 동적 균열진전 문제에 대한 애조인 형상 설계민감도 해석법을 개발하였다. 페리다이나믹스에서는 균열의 연속적인 분기를 다룰 수 있으며, Explicit 시간적분법을 채택한다. 설계민감도 해석은 애조인 변수법은 경로의존성 문제에는 적합하지 않으나 여기서는 응답해석의 경로를 이미 알고 있으므로 채택하여 사용할 수 있었다. 얻어진 해석적 설계민감도는 유한차분과 비교하여 그 정확성을 검증하였다. 유한차분법은 설계섭동량에 민감하여 비선형성이 강한 페리다이나믹스 문제에서 부정확한 설계민감도를 제시할 수 있다. 정확한 설계민감도 해석을 위해서는 이산화과정에서 $C^1$ 연속성을 가지는 체적율이 필요함을 알 수 있었다.

This study aims to identify on the possibility of the convergence education in engineering. Delphi survey on a panel of experts was chosen to be the main methodology for this study, drawing the main factors of convergence education in engineering. From Oct. 10 to Nov. 25, 2013, a three-round Delphi survey was implemented to collect data. A panel of eighteen experts were involved in this survey. For statistical processing, descriptive statistics including frequency, percentage, mean and standard deviation were carried out along with internal reliability test on the survey instrument. First, the possible convergence of disciplines in engineering were found to Design, Industrial design, ICT, Health care services, Video media, Business and Administration, Organizational psychology, Sociology, Humanities and Aesthetics. Second, the convergence education factors to be most important demanded creativity, idea generation techniques such as the expression of thought communication skills, technical expertise in the field per line, understanding of basic knowledge, verification of common elements among different disciplines, understanding of other disciplines fusion in engineering, artistry and imagination, etc. Third, requirements for the talented person of convergence were the open mind and enthusiasm, creative imagination, accept the opinions of others, skills capacity as a creative expression, and challenges. Above-mentioned requirements are found to be the necessary elements for convergence education.

This study designed and developed a class using review games as a way to enhance students' interest, class participation, and class comprehension in engineering theory classes, and explored their educational effectiveness. To this end, a review game strategy based on the Creative Training Technique was established and applied to three engineering theory subjects. The types of review games include Jin-jin-ga, Bingo, Challenge Golden Bell, Finding hidden terms, and Completing initial sentences. As a result of applying this review game strategy to the classes over the past decade, students' satisfaction and lecture evaluation scores significantly increased compared to before application, and it was confirmed that students' interest in and understanding of the class increased significantly. Furthermore, this gamification class strategy can be a way to increase students' participation in theory classes regardless of their major, and can be applied to non-face-to-face online classes.

지식정보화 시대에 있어서 전공교육과 더불어 창의적 인재를 양성하기 위한 창의적 사고 기법 향상에 관한 교육수요가 증가하고 있다. 학생들은 전공과목에 대한 중요성은 인식하고 있지만, 창의성은 선천적으로 타고나야 한다는 선입견이 크게 작용하여 창의성 계발에 별다른 노력을 기울이지 않고 있다. 반면, 기업의 경우 창의력과 응용력을 겸비한 인재를 더욱 중시하고 있다. 이러한 상황에서 러시아에서 개발된 창의적 문제해결기법인 TRIZ는 실무적 적용 가능성이 높은 기법이라고 할 수 있다. 본 연구에서 활용한 TRIZ는 실무문제를 명확히 정의하고 체계적인 분석을 통해 창의적 아이디어를 도출할 수 있는 가이드라인을 제시한다. 창의적 문제 해결 이론에서는 이론적인 내용의 숙지도 중요하지만, 실습을 통한 실무능력의 배양이 필수적으로 요구된다. 본 연구에서는 TRIZ기반 상용 소프트웨어인 CREAX를 활용하여 창의적 문제해결 실습교육을 수행한 결과를 바탕으로 학습자들의 창의적 문제 해결 능력 실습에 필요한 과정을 제안하였다.
