지식기반사회에서 산학협력의 중요성이 지속적으로 높아짐에 따라 정부는 산학협력 관련 다양한 사업을 추진하고 있다. 하지만 정부의 많은 지원에도 불구하고 만족스러운 성과를 거두지 못하고 있어 산학협력 성과를 확산하기 위한 실증적 성과분석의 필요성이 커지고 있다. 본 연구에서는 DEA를 활용하여 LINC+ 참여 대학의 산학협력 성과를 분석하였다. CCR 모형과 BCC 모형을 활용하여 효율성 분석을 수행하였으며, 규모효율성 분석을 통해 규모수익과 비효율 원인을 파악하였다. 또한 비효율적으로 운영되는 대학에 대하여 효율성 개선목표를 제시하였다. 분석 결과 대학이 위치한 지역에 따라 LINC+ 성과의 차이가 있으며, 대학별 비효율 개선을 위한 목표들이 상이한 것으로 나타났다. 본 연구 결과는 대학의 운영 효율성 제고와 경쟁력 강화에 기여할 것으로 기대되며, LINC+의 후속 사업 계획 수립에도 활용될 수 있을 것이다.

Along with the development of the automobile industry, the materials and processing technology of parts have also developed. In particular, various materials have been developed and applied to automobile bumpers, which are directly related to crash safety. In particular, the application of composite materials is expanding for weight reduction. In this study, a new composite material made of a mixture of carbon fiber and aramid fiber was developed and the possibility of application to an automobile bumper was reviewed, and significant results were obtained.

Atomic layer etching (ALE) is a promising technique with atomic-level thickness controllability and high selectivity based on self-limiting surface reactions. ALE is performed by sequential exposure of the film surface to reactants, which results in surface modification and release of volatile species. Among the various ALE methods, thermal ALE involves a thermally activated reaction by employing gas species to release the modified surface without using energetic species, such as accelerated ions and neutral beams. In this study, the basic principle and surface reaction mechanisms of thermal ALE?processes, including “fluorination-ligand exchange reaction”, “conversion-etch reaction”, “conversion-fluorination reaction”, “oxidation-fluorination reaction”, “oxidation-ligand exchange reaction”, and “oxidation-conversion-fluorination reaction” are described. In addition, the reported thermal ALE processes for the removal of various oxides, metals, and nitrides are presented.

The mass-rearing system for Neodryinus typhlocybae as a biological control agent of Metcalfa pruinosa was established. Depending on the density of host nymphs and plants, the average number of cocoons produced by the parasitoids was 5-8 and 70-150 cocoons per leaf and sapling of mulberry, respectively. There is a significant difference in cocoon length between females (6.10-6.46 mm) and males (4.20-4.62 mm). Sex determination of cocoons before emergence will be helpful for efficiently releasing this parasitoid in fields. The parasitic rate of N. typhlocybae at the semi-field condition was on average 13-17%. The release number of this parasitoid did not affect parasitism. Nevertheless, the population growth rate of M. pruinosa was reduced by increasing the release number of N. typhlocybae. The parasitoid offspring’s sex and bivoltine were influenced by the host age. On young host nymphs, the bivoltine portion of parasitoid increased. When parasitized on 4th or 5th nymphs, the offspring’s female ratio of N. typhlocybae increased. This result may be useful for potentially controlling mass rearing production of parasitoid.

In this work, the ablation behavior of monolith ZrB2-30 vol%SiC (Z30S) composites were studied under various oxy-acetylene flame angles. Typical oxidized microstructures (SiO2/SiC-depleted/ZrB2-SiC) were observed when the flame to Z30S was arranged vertically. However, formation of the outmost glassy SiO2 layer was hindered when the Z30S was tilted. The SiC-depleted region was fully exposed to air with reduced thickness when highly tilted. Traces of the ablated and island type SiO2 were observed at intermediate flame angles, which clearly verified the effect of flame angle on the ablation of the SiO2 layer. Furthermore, the observed maximum surface temperature of the Z30S gradually increased up to 2,200 °C proving that surface amorphous silica was continuously removed while monoclinic ZrO2 phase began to be exposed. A proposed ablation mechanism with respect to flame angles is discussed. This observation is expected to contribute to the design of complex-shaped UHTC applications for hypersonic vehicles and re-entry projectiles.
