국가적 차원에서 물을 사용하고 통제하는 일은 국민의 생활에 큰 영향을 주고 있기 때문에 대부분의 나라들은 주어진 여건에 맞게 효율적으로 물을 사용하고 홍수와 가뭄으로부터 국민의 생명과 재산을 보호하기 위해 많은 일들을 하고 있다. 이와 같은 목적으로 우리나라에서는 국가유량측정망을 구축하여 2007년부터 국가적인 차원에서 유량측정을 수행하고 있다. 하지만 국가유량측정망의 경우 유량자료의 제공에 주 목적이 포함되어 있어 실제 유량자료만이 아닌 수위자료만의 목적으로 운영되고 있는 수위관측소에 대한 평가가 부족한 것이 현실이다. 본 연구에서는 치수, 이수, 환경 목적을 위한 유량측정 지점 뿐만아니라 재난, 댐, 유지유량 관리 등과 같은 추가적인 목적으로 수위자료를 활용하는 지점들에 대하여 하천의 최상류 지점에서 하구까지 모든 지점에 대한 신뢰성 있는 수위정보를 실시간으로 파악할 수 있는 수위관측망을 구축하는데 목적을 두었다. 이를 위하여 금강홍수통제소, 한국수자원공사, 환경부에서 운영하는 수위관측소를 대상으로 홍수예보, 홍수 통제시설, 재난관리, 수자원 관리 및 공급, 수리권 갈등, 수질 등과 같은 다중목적을 적용하여 기존 관측소를 활용 목적별로 평가 하여, 각 기관의 중복투자에 따른 손실을 최소화 하고, 최적의 장소에 수위관측망을 구축하는 것이다. 이와 같이 도시, 댐 저수지 운영, 산간 및 농촌 지역 등의 현재 운영되고 있는 수위관측소 현황을 파악 한 결과 국토해양부 91개소, 한국수자원공사 18개소, 지자체 35개소, 환경부 26개소를 운영하고 있으며, 이중 환경부와 중복으로 검토된 지점은 15개 지점으로 나타났다. 최종적으로 수위관측소 운영 목적 및 지형학적 검토를 통하여 수위관측망을 검토한 결과 금강 권역의 하천 재난, 운영, 유지를 위해서 103개소의 수위관측소가 필요한 것으로 평가 되었다.

A smart grid is an electric-power grid that employs a new information technology.This technology makes it possible to exchange real-time energy information between suppliers and consumers, finally resulting in high energy efficiency. The energy management system in smart grid provides up to date information on electricity consumption as well as dynamic electricity price to consumers of smart grid system. However, the existing energy management systems only focus on pricing system, for example, real-time electricity prices. In this paper, we try to improve the existing energy management system and propose the energy management system that mainly focuses on the efficiency of electricity consumption. In the proposed management system, PMU(Phasor Measurement Units) installed in switchboards gathers electricity data in a real time. We also propose to use data mining method, which is applied to analyzed electricity data for improving energy efficiency. Also, the proposed energy management system is designed to efficiently control the electricity between PMU and management system in case of a shortage of electricity or surplus electricity.

Technology to optimize and utilize the use and supply of the electric power between consumer and supplier has been on the rise among the smart grid power market network in electric power demand management based on the Internet. Open Automated Demand Response system protocol, which can deliver Demand Response needed in electric power demand management to electricity supplier, system supplier and even the user is openADR 2.0b. This paper used the most credible, cosmopolitanly proliferated EPRI open source and analysed the variety of security vulnerability that developed VEN and VTN system may have. Using the simulator for attacking openADR protocol, the VEN/VTN system that has been implemented as EPRI open source was conducted to attack in a variety of ways. As a result of the analysis, we were able to get the results that the VEN/VTN system has security vulnerabilities to the parameter tampering attacks and service flow falsification attack. In conclusion, if you want to implement the openADR2.0b protocol system in the open or two-way communication environment smart grid network, considering a variety of security vulnerability should be sure to seek security technology and services.

It is very difficult that a company could grow with its own competitiveness in modern global competition era. The pattern of competition is changing from company-to-company to supply chain network-to-supply chain network. In order to enhance competitiveness and survive capability by combining inter-enterprises core competencies, the effort to integrate and optimize supply chain are increasing. The purpose of this study was to specify the effects of SCM characteristics on supply chain partnership and corporate performance through corporate characteristics such as agility and visibility. So as to verify hypotheses, multiple regression analysis was performed by using SPSS statistical package. The results showed that SCM characteristics had the positive effect on agility and visibility, and supply chain partnership and corporate performance was statistically influenced by agility and visibility. This study contributes on the SCM related research in that it investigated SCM activities of construction machinery industry.

The international standard certification evaluates the extend to which the supplier satisfies the international standard certification standards of the supplier of the product and the service, recognizes the quality assurance ability and reliability of the supplier, thereby resolving the international trade regulation that can occur to various fields and strengthening the network of the global partnership it is making an important contribution. Therefor, in this study, the survey was conducted on 153 companies of Korean import and export companies. The research method was empirically analyzed by the structural equation model. The results of the hypothesis test of this study are as follows. First, resource management factors among the international standard certification factors in the global trade supply chain integration had a positive effects on CRM satisfaction. Second, the measurement, analysis and improvement factors of international standard certification factors had a positive effects on CRM satisfaction. Third, CRM satisfaction has a positive effects on business performance. Through this study, it is concluded that the Korean import and export companies have an important role in improving the business performance of the global trade partners.

Cyber security in the automobile sector is a key factor in the life cycle of automobiles, and cyber security evaluation standards are being strengthened worldwide. In addition, not only manufacturers who design and produce automobiles, but also due to the nature of automobiles consisting of complex components and various parts, the safety of cybersecurity can be secured only when the implementation level of the cybersecurity management system of companies participating in the entire supply chain is evaluated and managed. In this study, I analyzed the requirements of ISO/SAE 21434 and TISAX, which are representative standards for evaluating automotive cybersecurity. Through a survey conducted on domestic/overseas company security officers and related experts, suitability and feasibility were reviewed according to priorities and industries, so 6 areas and 45 evaluation criteria were derived and presented as final evaluation items. This study is meaningful as a study in that it presented a model that allows companies participating in the automotive supply chain to evaluate the current cybersecurity management level of the company by first applying ISO/SAE 21434 and TISAX overall control processes before uniformly introducing them.

This paper examined the supply chain management Integration factors and environmental performance in Korean industry. Focusing on SCM Integration, GreenSCM practice, and environmental performance factors, purpose of this study is finding linkage between SCM Integration factors with new environmental practice factors and environmental performance. Based on the analysis of eighty-eight cases, the following results were found. First, We found External environmental collaboration factors and Internal environmental monitoring factors within Green Supply Chain Practices. Second, SCM Integration have a positively significant influence on environmental performance. Third, Internal environmental monitoring factors have a positively significant influence on Environmental performance but External environmental collaboration factors doesn't. This study suggests that only with high level of Integration firms may have good result on entire supply chain environmental performance. Finally, our empirical evidence shows that company should be prepared for new environmental trade regulation with Green Supply chain management integration.
