3D 프린팅과 전문대학 인력에 대한 기업 수요조사를 통한 전문대학 산학협력 활성화 방안 연구
유충현(Ryu, Chung-Hyun) 한국산학기술학회 2016 한국산학기술학회논문지 Vol.17 No.3
산학협력은 국가경쟁력 강화를 위해 필요한 정책이나 기업 수요가 지속적으로 감소하고 있어 산학협력 활동이 위축받고 있다. 특히 산학협력의 범위를 일부로 한정하여 판단함으로서 전문직업인 양성을 위해 노력하는 전문대학이 일반대학에 비하여 산학협력에 기여하는 바가 미흡하다는 인식이 있고 이것은 전문대학 산학협력 활성화를 저해하고 있다. 전문대학 산학협력을 활성화하기 위해서는 기업 수요를 정확히 파악하는 것이 무엇보다도 중요하다. 본 연구는 기업을 대상으로 설문조사를 실시하고 3D 프린팅과 전문대학 졸업생의 활동분야를 비교분석하여 3D 프린팅을 활용한 전문대학 산학협력 활성화 방안을 제안한다. 그리고 전문대학과 일반대학의 주요역할을 기술사업화 절차에 따라 기업 수요를 분석하여 기업과 전문대학 그리고 일반대학의 협력모델을 제안한다. Academia-industrial cooperation policy is essential to enhance national competitiveness in Korea. Although government and academia have invested in policies and supported industries, academia-industrial cooperation is not operated actively. This is one of the reasons why industrial demand for cooperation has continuously decreased. There are thoughts that universities' outcomes are larger than colleges' outcomes in academia-industrial cooperation, which could be a barrier to academia-industrial cooperation for colleges. It is important to understand industry demands in order to activate this type of cooperation. We propose a way to achieve this based on survey data for 3D printing and college graduates. Interactive cooperation among industries, colleges, and universities is suggested in the process of technical commercialization, such as TRL (Technology Readiness Level).

A study to reduce the substrate warpage on flash light sintering for copper nanoparticles was investigated. In order to minimize the substrate warpage, two-step flash light sintering method was performed. The flash light sintering process was divided into a preheating step and a main sintering step. To find the optimum sintering conditions of copper nanoparticles, the flash light conditions (irradiation energy, pulse number, on-time and off-time) was varied. The microstructures and transformation crystal phase of the sintered copper nanofilms were analyzed by scanning electron microscopy. In addition, the sheet resistance was measured using a four-point probe method. Also, the thickness of copper nanofilms was measured by alpha-step. From these results, it is found that the flash light sintered copper nanofilms have a low resistivity without any damage to the thin polyimide substrate.

This study was performed to evaluate bonding strength of the composites section made of existing concrete and repair mortar in domestic. The pull-out tester was used to test bonding strength for the composites section made of each materials. The results of the test was used to evaluate the korean industrial standard of polymer modified cement mortars for maintenance in concrete structures.
