해양수산부가 구축한 초고속 해상무선통신망(LTE-Maritime)은 연안으로부터 최대 100km 해역을 항해하는 선박들에게 지능형 해상교통정보서비스(e-Nav)를 제공하기 위한 기반 통신 인프라다. 선박에서 e-Nav 서비스를 제공받기 위해 LTE-M. 무선설비는 선내 고정 설치되어 유선으로 연결된 표시장치와 연동이 필요하다. 이는 공간이 협소하고 밀폐된 소형선박에 설치의 어려움뿐 아니라 선내 센서를 비롯한 다양한 IoT 기기 등과의 연결성에 제약을 줄 수 있다. 또한 선박이 육상의 LTE-M. 기지국과 멀리 떨어질 경우, 다운링크에 비해 업링크 통신품질이 상대적으로 취약해져 긴급 조난 신호를 비롯한 위험상황의 전달에 문제가 발생될 수 있다. 본 연구에서는 LTE-M. 망의 무선설비 다각화 사업으로 추진·개발된 소형선용 WiFi 및 업링크 향상용 무선설비의 실해역 성능 시험 방안을 고찰하여, 선내 WiFi 무선 품질을 평가하기 위한 성능 지표를 비롯해 업링크 통신속도 개선 등을 확인하기 위한 상호운용성 성능 시험 방안을 제시하고자 한다.

Recently, as part of an effort to realize the low-carbon green growth, the research to measure the degree of greening about the road facility with United States as its center was performed. In addition, the Green-road certification is enforced and applied. In this study, we would like to examine the applicability of the green-road certification to domestic road to promote the settlement of green-road certification system to contribute the related industry development for the green technology development and application and spread in the roads sector.

With the increase in the demand for sustainable and environmentally-friendly development, Green Building Certification System came into force in 2002, Evaluation parts of Green Building Certification System are divided into land use and transportation, energy, ecological environment, and indoor environment. Alloted point for the part of energy is larger than other part, thus we can say that this part is very important to increase the green building performance. This study aims to analyze the present condition of design and construction for the part of energy in the certificated green school building. Total 40 certificated school buildings were selected and average scoring rate of each item was evaluated. Key particular to be considered were suggested to improve the item of energy consumption.

The purpose of this study is to investigate the characteristics of disaster preparedness for young children in educare curriculum and accreditation criteria. As a result, it is revealed that educare curriculum and accreditation criteria had the content of disaster preparedness for children. In addition, it is necessary to pay attention to the disaster preparedness for young children.

In this study, the effectiveness of the innovative company certification system, which is one of the important means of the SME innovation promotion policies, was examined in terms of technological innovation activity and performance. To this end, we used the results of 'SME Technology Statistical Survey' conducted by the Small and Medium Business Administration and the Korea Federation of Small and Medium Business in 2013~2015 to compare the innovative SMEs that have received the certifications such as Venture Certification, Innobiz Certification, and Mainbiz Certification with the general SMEs that did not. As a result, it was found that the innovative SMEs have comparative advantage in many detailed indicators related to the technological innovation activity and performance. However, the ratio of external use of R&D expenditure, the number of technology development attempts and the number of successes were not different according to the survey year, so it is necessary to strengthen the follow-up management of the system. On the other hand, the proportion of self-procurement R&D expenditure of the general SMEs was significantly higher than that of the innovative SMEs in all three-year surveys. Therefore, it is necessary to regulate the government funding for the innovative SMEs to be used as a complementary material, not as a substitute for their own R&D investment. In addition, the technological innovation activity and performance of a company were more influenced by the size of the company and the participating industry rather than by the certification, so it is necessary to consider it when establishing the technology innovation promotion policies.

Environmental Performance Index(EPI) has shown some limitation. Since it has lack of analysis for the relation between environmental performance and business performance, and public information. Therefore it could not provide valuable information for the shareholders to decide for the investment. In this paper by using Analystic Hierarchy Process (AHP), EPI was calculated giving some weighted scale for each environmental items. Improvement of pollution treatment, general management data such as EMS system, and environmental improvement for the products and process were the main three items when decision makers in bankings are considering the investment for a company. In empirical case, companies which has Environmental-Friendly Coorperation Award from MOE and ISO 14001 certification had shown strong relation between business performance and environmental performance.

Ethical and technical problems are becoming serious as the industrialization of artificial intelligence robots becomes active, research on risk is insufficient. In this situation, the researcher developed 52 verified indicators that can measure the body, rights, property, and social risk of artificial intelligence robots. In order to develop measurement indicators for each type of risk of artificial intelligence robots, 11 experts were interviewed in-depth after IRB deliberation. IIn addition, 328 workers in various fields where artificial intelligence robots can be introduced were surveyed to verify their fieldwork, and statistical verification such as exploratory factor analysis, reliability analysis, correlation analysis, and multiple regression analysis was verifyed to measure validity and reliability. It is expected that the measurement indicators presented in this paper will be widely used in the development, certification, education, and policies of standardized artificial intelligence robots, and become the cornerstone of the industrialization of artificial intelligence robots that are socially sympathetic and safe.

Recent national policy agenda of 'Low-Carbon Green Growth' has been implemented as the important vision of the country. The government has set a target of entering the seven major world powers of Green Nation at 2020, and five major world powers at 2050. In order to achieve the goal, the reduction of greenhouse gases and the composition of green land and transportation has been promoted as an important policy. In a construction industry sector, policies and technologies for reducing greenhouse gas emissions and energy have been actively developed. In the case of developed countries, research for green road infrastructure has been conducted, which is the basis for certification system of green highway. This paper benchmarks the policies and cases of developed countries, verifies the applicability in the domestic road sector, and suggests the introduction of the certification system of green highway.
