국내 물관련 건설 및 설비 업체를 대상으로 하는 설문조사 및 인터뷰 결과 국내 물 관련 기업들의 해외진출 시 가장 큰 애로사항은 해외경험 직원의 부족으로 나타났다. 해외사업 확대를 위해서는 고부가가치 업무를 수행할 수 있는 고급기술자와 관리 인력의 양성이 시급하며, 특히 건설사업관리(CM, PM)나 설계/엔지니어링을 담당할 고급 기술 인력의 양성이 필요한 것으로 조사되었다. 경쟁력있는 글로벌 기술 관리 인력의 양성은 정부의 주도하에 기존의 물 관련 기관의 교육프로그램 통합 운영 및 내실있는 전문 수자원 대학원 운영 등 장기적인 정책적인 지원이 필수적이다. 또한 현재 해외 물시장 정보 수집의 활성화를 위하여 국토교통부, K-water, 해외건설협회 등이 연계한 물 산업 전담 정보시스템 구축과 중점 수출대상국 선정 후 대상국에 해외지부 운영 등이 필요할 것이다. 금융지원과 관련하여 해외건설 금융지원 강화를 위한 글로벌 인프라펀드 조성, 해외건설 보증한도 확대 등이 필요하며, 'EDCF 등 공적금융의 물산업 지원 확대 등 재정지원을 위한 정부의 적극적인 역할 역시 중요하다. 해외 물시장 진출을 위해서는 국내 물기업들의 역량을 결집하는 것이 필요하며, 이를 위해서는 효율적인 공공 민간 협의체의 설립 및 운영이 이루어져야 한다. 전 세계적으로 물 산업은 높은 공공성과 함께토탈 솔루션 역량이 중시되고 있으며, 이런 시장환경에 부응하여 네덜란드, 독일 등 물산업 수출 강국은 자국의 물관련 분야를 결집하는 워터 파트너십을 설립하여 국제사회에서 위상과 세계시장 점유율을 동시에 높여가고 있는 실정이다. 이들 국가 워터파트너십의 공통적인 설립 목적은 궁극적으로 자국 물 관련 산업, 국가 브랜드 및 이니셔티브와 관련되는 국제협력, 정책 분야 등의 결집이다. 다시 말해서 정부가 주축이 되어 관 산 학 연 기관간의 정보제공, 협력 등을 도모하고 있으며 이 네트워크의 구심점 역할 및 촉진은 자국의 워터파트너십이 맡고 있는 것이다. 해외 물 시장 확대를 도모하고 있는 우리나라도 국가차원의 장기적이고 지속적인 해외 물산업 네트워크 구축을 위해서는 정부-공기업-민간기업 등의 협력을 토대로 한 Korea Water Partnership을 조속히 설립하는 것이 필요하다. 이를 위해서는 국토부, 환경부 등 물 관련 부처는 물론 글로벌 네트워크를 구축하고 있는 외교부, 무역협회 등 유관기관의 정보 연계 및 협조 체계 역시 필요하다. 정부부처 차원의 조직은 국제 정치 아젠다(agenda)에 중대한 영향을 줄 수 있으며, 경쟁적 우위와 유사기관 간의 정보와 네트워킹의 공유를 보다 원활하게 할 수 있기 때문이다. Korea Water Partnership에서는 한국이 보유하고 있는 선진 수자원기술 및 경험을 해외에 소개하고, 정부 및 민간 기업들의 물 산업 수출역량을 적극적으로 피력할 수 있는 기회를 마련하며, 국제사회에서 물 강국으로서 한국의 위상을 높일 수 있는 홍보 마케팅 창구로서의 역할을 기대할 수 있을 것이다.

Malfunctioning of telecom systems can have serious implications on the safe navigation and operation of vessels and off-shore plants. Most safety-related accidents incur significant monetary damages and pollution due to complicated arrangements of the working environments and facilities. Therefore, an automated monitoring system that can collect data from configured telecom equipment connected to a network based on IP is required to ensure safe navigation and operation of such crucial institutions. This paper reports a list of such system requirements, system functions, and user-centered requirements based on the NORSOK T-100 (a standard of telecom management system). These findings were made through research with the newly designed and developed telecom management system (TMS). The TMS was tested by a testbed configured with CCTV, PA/GA, and other network equipment.

Power supplies make the load compatible with its power source. DC power supplies are extensively used with most electrical and electronic appliances such as computers, television, and audio sets. The presence of non-linear loads results in a low power factor and higher harmonics in the power system. Several techniques for power-factor correction and harmonic reduction have been reported in the literature. This paper proposes a bridgeless boost converter that improves the power factor and reduces the harmonic content in input line currents as compared to full-bridge rectifiers. This bridgeless boost converter eliminates the need of a line-voltage bridge rectifier in conventional boost converter and thereby reduces conduction losses. The effectiveness of the proposed scheme is verified by computer simulations by using the PSIM software.

The global demand for carbon neutrality in response to climate change is in a situation where it is necessary to prepare countermeasures for carbon trade barriers for some countries, including Korea, which is classified as an export-led economic structure and greenhouse gas exporter. Therefore, digital transformation, which is one of the predictable ways for the carbon-neutral transition model to be applied, should be introduced early. By applying digital technology to industrial gas manufacturing facilities used in one of the major industries, high-tech manufacturing industry, and hydrogen gas facilities, which are emerging as eco-friendly energy, abnormal detection, and diagnosis services are provided with cloud-based predictive diagnosis monitoring technology including operating knowledge. Here are the trends. Small and medium-sized companies that are in the blind spot of carbon-neutral implementation by confirming the direction of abnormal diagnosis predictive monitoring through optimization, augmented reality technology, IoT and AI knowledge inference, etc., rather than simply monitoring real-time facility status It can be seen that it is possible to disseminate technologies such as consensus knowledge in the engineering domain and predictive diagnostic monitoring that match the economic feasibility and efficiency of the technology. It is hoped that it will be used as a way to seek countermeasures against carbon emission trade barriers based on the highest level of ICT technology.

As the severity of environmental pollution has increased, restrictions on air pollution have been strengthened. Stringent regulations have been imposed, not only on marine diesel engines but also on automotive and industrial power plants. Thus, biofuels have been directly applied in practical engines and used in training ships for basic research. Even though a high biofuel percentage cannot be used in a training ship engine for safety reasons, because this type of engine is larger than those used in institutional laboratories, the results will provide important basic information that will allow organizations to determine the status of a large output. Biodiesel fuel was studied to determine how it would affect the combustion characteristics and exhaust emissions of a marine diesel generator engine. The main results can be summarized as follows. Because the physical and chemical compositions of biofuels are similar to those of diesel fuel, it was found that their practical use was possible in a training ship. The specific fuel consumption and NOx increased, whereas a tendency was found for carbon monoxide and soot to decrease. In addition, no significant pressure change difference was found between the diesel fuel and biofuels.

The research team for the virtual construction development was established with the support of Korea Ministry of Construction and Transportation, and KICTEP (Korea Institute of Construction and Transportation Technology Evaluation and Planning). Its aims are to develop system that is to improve productivity & quality, to create a higher value-added business, and to cultivate international competitiveness in the construction industry. The virtual construction system is a design, engineering, and construction management information system that allows the project participants to effectively share the information throughout the construction life cycle with the support of 3D and design information. To achieve this, the research team focuses on developing several systems. First, the team focuses on developing for the pre-planning, the structural engineering, MEP, and the 3D based estimation system. Second, they focus on developing a simulation system for the construction process planning and feasibility study with help of the virtual reality technologies. Third, they focus on developing the CPLM (Construction Project Life-cycle Management) system for managing construction project data, and the decision support system that makes the collaboration among the project participants based on 3D technologies and information. We also focus on developing the SDAI (Standard Data Access Interface), the localized guideline for 3D design, and a training program. In addition, we focus on developing the undeveloped area of the commercial system and building an environment that can support the communication and collaboration in the construction life-cycle rather than developing the existing and commercialized system.
