우리나라에서의 기존 산학연 협력에 관한 연구는 주로 대학의 역할을 강조하였다. 그러나 출연(연)이 지난 $30^{\sim}40$년간 연구개발 수행과정에서 축적된 혁신역량을 국가차원에서 효율적으로 활용할 필요가 있다. 특히 최근 들어 중소기업의 기술경쟁력 강화에 대한 관심이 증대되고 있는 시점에서 정부출연기관에 의한 중소기업 지원의 타당성과 필요성에 대하여 실증적으로 도출한 연구가 부족한 것이 사실이다. 이 연구는 기존의 추상적인 정책제안을 탈피하여 1,077개의 중소기업과 13개 정부연구기관의 373명의 연구원들을 대상으로 한 광범위한 설문조사를 분석하여 중소기업이 실질적으로 요구하는 기술의 유형과 지원의 형식 및 정부연구기관의 연구원들이 체감하는 기술공급의 문제점들을 중심으로 고찰하고자 한다. 설문조사결과 정부연구기관이 지역을 기반으로 한 중소기업과 대학 등 국가기술혁신체제 속의 연구개발주체들을 네트워크화 하여 기술지식과 정보의 유통, 활용을 촉진하는 매개체로서의 역할을 수행하여 지역혁신 지원 조직이 공동으로 지역 중소기업을 위한 산 학 연 종합기술지원 사업을 추진할 것을 요구함을 발견하였다.

With the core technology of 4th Industrial Revolution, the industry of Smart-Farm technology has applied agriculture automation system instead of traditional agriculture. This study were explored to introduce undergraduate research practices by using Smart-Farm technology to promote to build new lectures focused on this technology. The mentor-mentee program were conducted by a graduate student and a professor. Our team implemented surveys to develop nutritionally-balanced diets with fresh Smart-Farm vegetables. After all, sensory evaluation were explored to improve food quality by recruitment of 29 panel. New dishes using fresh vegetables were considered to be nutritionally-balanced but the results of sensory evaluation were low. Survey results from the panel suggest to improve the quality of fresh vegetables texture. To intake adequate nutrients intakes, educational program and nutrition consults should be promoted for undergraduate program. Demand on Smart-Farm technology was high according to panel opinion. In conclusion, the results of this study will be useful as basic data for the planning of Smart-Farm technology utilization program for the undergraduate students in the department of food science and nutrition.

One of the important requirements in user beam lines of the KOMAC (Korea Multi-purposeAccelerator Complex) 100-MeV linac facility is the ±10% uniformity of the particle distributionover the irradiation area. For a long beam line, we found that it can be achieved by using theusual octupole method. However, the lengths of other beam lines are too short to generate uniformirradiation on target by using two octupole magnets. In this work, we studied the combination ofan octupole magnet, which makes uniform particle distribution in one direction, and a scanningmagnet, which shifts the beam center in the perpendicular direction and makes uniform irradiationby adding several pulses. This report summarizes the condition of uniform beam irradiation andthe characteristics of beam on target in the KOMAC 100-MeV beam line.

One of the PEFP (Proton Engineering Frontier Project) 100-MeV beam lines requires a large and uniform irradiation field of ±10% uniformity in the target area of 300 mm × 300 mm. We studied the nonlinear optics method by using two octupole magnets in order to achieve a large uniform field at the target. We found that the particles can be uniformly distributed within ±10% in a 300 mm × 300 mm irradiation field at the target. We also studied the conditions of the quadrupole and the octupole magnets to meet the requirement of a large and uniform irradiation field.
Study on the RF Set Point for the PEFP DTL by Using a Phase Scan Method
장지호,권혁중,조용섭 한국물리학회 2012 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.61 No.11
The drift tube linac (DTL) is used to accelerate proton beams from 20 MeV to 100 MeV in the linear accelerator of the Proton Engineering Frontier Project (PEFP). The phase scan signature method is a common technique to determine the radio-frequency (rf) set point, including the rf amplitude and phase, in DTL tanks. In this work, we applied the phase scan method to the first tank of the PEFP's DTL in order to study the procedure for determining the rf set point by using artificial experimental data generated by using the PARMILA code.
