Edge computing, which is computing on the edge of the network, is becoming a market value as a means of overcoming the fear of communication disconnection and delay reduction, which are the technical weaknesses of cloud computing. Edge computing is continuously expanding applications in various applications such as safety industry, smart factories, autonomous vehicles, mobile communications, and AR/VR. Looking at edge computing trends from Microsoft, IBM, HPE, and Dell EMC, current edge computing must be understood as an integral binding technology and not as a simple complement to the cloud. This paper examines market trends in edge computing and analyzes the impact of edge computing on major related industries.

In this paper, we analyze the current research technology trends through the literature reviews of technical outlines of electric vehicles and hydrogen fuel cell vehicles, domestic and overseas policy trends, etc. After analyzing the literature, we found out while the re-use and recycling of waste batteries and the in-wheel motor systems are essential areas for the development of electric vehicles and hydrogen fuel cell vehicles, the related research is not quite sufficient, so the direction for further research is proposed at the conclusion.

Physical rehabilitation consists of exercises that help individuals who have suffered injury, disease, or nervous system disorders to recover lost or impaired functions. The exercises need to be tailored to the degree and type of the patient's condition. To this end, a comprehensive rehabilitation data delivery system that connects medical institutions and local communities should be established, and an intelligent rehabilitation service technology should be developed. An intelligent rehabilitation service integrates and manages the patient's health information provided by medical institutions and the overall function evaluation information measured in the community. Based on the collected data, personalized rehabilitation services can be provided. We examine supportive policies and technological trends for rehabilitation exercise and sports. Additionally, we investigate development trends and key technologies of intelligent rehabilitation services being developed at ETRI.

This study utilizes DEA/Window analysis in order to investigate the relative efficiency levels of korea national university libraries during the period of transition 2004-2008. The empirical results show the following findings. Firstly, a technical efficiency was not efficient which was a scale efficiency rather than a pure technical efficiency in 2008. Secondly, a technical and pure technical efficiency has increased steadily from 2004 to 2008(but a technical, pure technical efficiency has decreased since in 2008). As a result, a technical efficiency increase can be explained by a pure technical efficiency increase.

각 기업에게 신뢰성있는 가상 인트라넷 서비스를 제공하기 위해서는, 통신망의 품질, 기업내부 정보의 보호 등을 확실하게 보증할 수 있어야 하며, 기업 업무에 필요한 각종 응용 서비스를 제공하여야 한다. 본 고에서는 이러한 가상 인트라넷의 개념 구조를 제시하고, 이 서비스를 제공하기 위한 기술적 요구사항인 백본망의 고품질 및 VPN 기술과 기업 응용 서비스 기술을 분석하며, 미국, 일본 등의 통신사업자 및 서비스 제공자들이 제공하는 서비스의 동향을 소개한다. 우리나라에서는 아직까지 이러한 서비스가 도입되지 않았으나, 자체 기업망을 가지지 못한 중소기업이나 기관 등에게 업무의 효율성 증진 및 경쟁력 강화를 위해 상당히 유용하리라 예상된다.

안테나는 무선 시스템의 성능을 향상시킬 수도 있고 저하시킬 수도 있는 중요한 부분이다. 따라서 안테나의 성능과 특성을 이동체의 전파환경까지 고려하여 광범위하게 연구하고 있으며, 안테나의 설계에 있어서 안테나 자체뿐만 아니라 전파전파, 무선 시스템, 전파환경까지 고려하게 되었다. 본 고에서는 이동통신에 사용되는 안테나를 중심으로 최근 기술동향을 기술함으로써 기술장벽을 극복하고 국제경쟁력을 확보하기 위한 기회를 제공하고자 한다.
