This study identified the core competencies of aircraft maintenance quality engineers and compared the importance and retention of core competencies. Through literature research, 21 core competencies were derived in three areas of management technology, elemenal technology and collaboration technology, and a survey was conducted on the importance and retention of core competencies for 42 aircraft maintenance quality engineers. As a result of the survey, the importance of all core competencies of aircraft maintenance quality engineers is 3.95/5 on average, and the retention of all core competencies is 3.99/5 on average. 'Risk Management’, ‘Creating Document’, ‘Honesty/Moral’ were identified as the most important competencies in each area, and ‘Quality Management’, ‘Language’, ‘Honesty/Moral’ were identified as the most possessed competencies in each area. An IPA (Importance-Performance Analysis) was performed to analyze the details. Through IPA, ‘Risk Management’ and ‘Safety Management’ were evaluated as having a low degree of retention compared to a high level of importance. Therefore, they were identified as a core competencies that need to be improved first. In addition, the characteristics of each core competency and the recognition level in the field were also identified. This study will be helpful in defining the roles and functions of aircraft maintenance quality engineers to improve flight quality and prevent aviation accidents.

Nonlinear analysis for seismic performance evaluation of existing building usually takes 4~5 times more than linear analysis based on KBC code. To obtain accurate results from the nonlinear analysis, there are a lot of things to be considered for nonlinear analysis modeling. For example, reinforcing layout, applied load and seismic details affect behavior of structural members for the existing building. Engineer-oriented computerized system was developed for engineers to evaluate effective seismic performance of existing buildings with abiding by seismic design principles. Using the engineer-oriented program, seismic performance evaluation of reinforced concrete building was performed. Nonlinear hinge properties were applied with real time multiple consideration such as section layout, section analysis result, applied load and performance levels. As a result, the building was evaluated to satisfy LS(Life Safety) performance level. A comparison between engineer-oriented and program-oriented results is presented to show how important the role of structural engineer is for seismic performance evaluation of existing buildings.

레저보트디자인은 공학적 기술을 바탕으로 감성적 디자인이 결합된 종합적 디자인을 필요로 하기 때문에 무엇보다 디자인과정에서 디자이너와 엔지니어의 지속적인 정보교류와 협력이 필요하다. 따라서 본 연구에서는 이러한 특성의 레저보트디자인에 적합한 디자인프로세스와 디자인방법을 제안한다. 디자인프로세스는 디자이너의 사고프로세스를 바탕으로 이해하기, 탐색하기, 해석하기, 개발하기, 검증하기의 다섯 단계로 구성하며 각 단계마다 디자이너와 엔지니어의 협력과 의사소통을 촉진하는 디자인방법을 제시한다. 그리고 이 프로세스와 방법을 하이드로포일보트디자인에 적용하여 평가를 실시한다. 평가결과 본 연구에서 제시된 디자인방법들은 디자이너와 엔지니어 사이에 협력과 의사교환을 촉진시키며 또한 둘 사이에 상호 이해와 신뢰감을 형성하는데 도움이 되는 것으로 나타났다.

The purpose of the study is how to educate construction IT convergence for BIM engineers. With the advent of the fourth industry in recent years, BIM has attracted much attention in the construction industry. However, There are not many Construction-IT experts who can link the 4th industry with BIM. There is an increasing demand for construction IT convergence education that connects the 4th industry and BIM. How should we design construction IT convergence training for construction engineers? We surveyed 38 BIM engineers and 88 construction professionals in order to find a direction for construction IT convergence education for BIM engineers.
