Recently, the government has provided support such as entering new markets, expanding sales channels, and supporting manpower, not just in the form of funding, to efficiently and effectively support limited national resources to improve corporate performance. In this study, we tried to find out the effect of government support for companies that have benefited from the Excellent Technology Research Center Project (ATC Project) and the World Class 300 project using propensity score matching. As a result of the analysis, the effect of government support for the ATC project became visible after the appointment period, while the effect of the World Class 300 project was insignificant. This means that when the size of the company is small, the effect of government support is more pronounced. This suggests that in order to maximize the effectiveness of government support, appropriate national policy interventions such as government innovation funding are needed when the size of the company is small. In this study, differences in the timing, performance indicators, and company size of policy support effects were found in the growth stage of a company from a mid- to long-term time series perspective, suggesting that support policies based on this need to be adjusted and redesigned.

Recently, carbon composites have been applied to various fields. However, carbon composites have not been applied to the fishing vessel field due to its structure standards centered on glass composites. In this study, a structural strength evaluation study was conducted for the application of carbon composites in the fishing vessel field. Hull minimum thickness verification test and hull joint verification test were conducted. Compared to glass composites, the verification was based on equivalent or better performance. The results show that carbon composites can reduce the weight by 20% compared to glass composites. For hull joints, it was necessary to increase the thickness of the joint seam by the thickness of the hull to apply carbon composite. Through this study, a standard for the application of carbon composites to fishing vessel can be established.

탄소전극과 이온교환막을 결합한 축전식 탈염(CDI)을 이용하여 셀 구조와 셀 전위에 따른 구리 이온의 제거 특성을 연구하였다. 탄소전극과 이온교환막의 결 합 방식에 따라 4종류의 셀에 대해 실험한 결과 양이온, 음이온교환막을 결합한 셀(MCDI)에서 구리 이온의 제거율과 전하효율이 가장 높은 것으로 나타났다. 셀 전위에 따른 영향을 분석한 결과 0.6 V 이하에서는 전기이중층에 의한 전기 흡착(electrosoprtion)에 의해, 그리고 0.6 V 이상에서는 구리 이온의 전착 (electrodepostion)반응에 의해 구리 이온이 제거됨을 확인하였다. 또한 1.2 V 이상에서는 물이 전기분해되어 전하효율이 감소하였다. MCDI 셀의 운전결과 전하효율은 80% 정도로 구리 이온을 포함한 중금속 이온을 제거하는데 효과적인 것으로 판단되었다.
