세계은행의 발표에 따르면 전 세계적으로 개인 간 해외송금 시장의 규모는 지속적으로 성장해 왔으며, 향후에도 지속적으로 성장할 것으로 전망된다. 이러한 글로벌 송금 시장의 확산과 맞물려 이동통신 네트워크의 글로벌화와 스마트폰의 확산 등 통신 기술 및 서비스 진화에 따라 모바일 네트워크를 통해 간편하고 신속하게 송금할 수 있는 모바일 송금 서비스 시장이 국내외에서 급속하게 팽창하고 있다. 이에 세계이동통신사업자협회(Global System for Mobile Communications Association: GSMA)의 MMT(Mobile Money Transfer) 프로그램, 케냐 및 일본의 모바일 송금 서비스 제공 사례를 중심으로 서비스 제공 시스템 및 그 이용에 따른 장 단점, 가치사슬, 서비스 유형 등을 간략하게 살펴보았다. 이를 바탕으로 모바일 송금 서비스 제공 과정에서 나타날 수 있는 규제 이슈들을 분석해 보았다. 그리고, 국내 이동통신 사업자가 MMT 서비스를 본격적으로 제공하는 경우에 고려해야 할 규제 요소들과 안전하고 효율적인 MMT 시장의 활성화를 위해 필요한 규제정책 방향을 검토해 보았다.

As the volume of internet rapidly increases, the number of IPv4 addresses available is quickly declining, while transition to IPv6 is being delayed. As a interim solution, Variable-Length Subnet Masking(VLSM) addressing scheme, which varies the length of each IP address allowing more efficient, is being used. This paper suggests effective example of network based on virtual network with topology designed using VLSM charting rather than usual theoretical approach in VLSM, which allows more efficient use of address space.

국제 무역에 있어 한 중 일 삼국은 동아시아에서 차지하고 있는 비중이 클 뿐만 아니라, 전 세계 컨테이너 물동량의 30% 이상을 차지하며 세계 물류 흐름에서 큰 역할을 차지하고 있다. 하지만 각국의 물류 정보시스템이 각각 다르고, 관리 체제나 연계 방안이 마련되어 있지 않아 정보 연계 시 많은 문제점이 발생하고 있다. 이를 해결하기 위해 한 중 일 삼국은 정보를 공유하고 관리할 수 있도록 동북아 물류정보 서비스 네트워크(이하 NEAL-NET) 구축 사업을 진행하고 있다. 본 논문에서는 NEAL-NET 프로젝트의 진행 사항과 의의를 살펴보고, 추후 국제 물류정보 공유 협력을 위한 표준화 방안에 대해 연구하였다.

All of the military aircrafts in Korea Air Force are administered and operated together in the same system regardless of whether they are equipped with the data communication capability or not. The absence of the data communication capability in some of the aircrafts might increase whole kill chain hour at the point of the Network Centric Warfare achievement. Network synergy effects cannot also be desired if the section which is not connected to the network influences to the whole tactical network. Equipping aircrafts with the data communication capability could be done by upgrading the aircrafts, but resulting in high costs and long updating time. This paper is a research about the design and implementation of the UMPC based Data Link System to aircrafts that do not have the data communication capability. The proposed system grafts the UHF-based wireless modem technology and the aircraft flight mission support software onto the off-the-shelf UMPC and GPS system. The employed UHF radio equipment allows communicating tactic data with another aircrafts on the air, the ground control point, and even the Tactical Air Control Party(TACP) control vehicle that achieve missions with aircrafts. It thereby increases such capabilities as navigation aid, situation awareness, quick target identification and attack. We also applied Closed Air Support(CAS) scenarios, which is very close to the real environment, to the experiments of the proposed system. The experimental results show that the proposed system could support the data communication capability effectively and the flight mission at low costs of money and time.

Korean military is propelling the M&S on new warfare concept, such as NCW(Network Centric Warfare) which is the aspect of future war. IPv6 is the essential element of next generation defense network which is supporting the future battlefield. There have been many studies on allocating the IPv6 address for next generation defense network. However, they assigned the address by level on the basis of the military organization or assigned it from the service network, so it had the defect, the big size routing table. This study reviews the topology of next generation defense network and adjusts the position of service network ID on the basis of the network topology. Finally, it improved the efficiency of route aggregation and minimized the routing table size in comparison with the previous studies and it was proved by OPNET simulator.

The unmanned aerial vehicle that emerged with the 4th Industrial Revolution attracts attention not only from Korea but also from around the world, and its utilization and market size are gradually expanding. For the first time, it was used for military purposes, but it is currently used for transportation, investigation, surveillance, and agriculture. China, along with the US and Europe, is emerging as a leader in the commercial unmanned aerial vehicle market, and Korea, which has the world's seventh-largest technology in related fields, is striving to promote various technology development policies and system improvement related to unmanned aerial vehicles. Military drones will revolutionize the means of war by using a means of war called an unmanned system based on theories such as network-oriented warfare and effect-oriented warfare. Mobile equipment, including drones, is greatly affected by environmental factors such as terrain and weather, as well as technological developments and interests in the field. Now, drones are being used actively in many fields, and especially in the military field, the use of advanced drones is expected to create a new defense environment and provide a new paradigm for war.

The purpose of this study is to provide developmental direction of medical education by analysing graduate medical school student's perception structure about 'good doctor' and the difference between graduate medical school student's perception structure about 'good doctor' before and after clerkship. Subject of study is medical students in 1st~4th year. NetMiner 4.0 program, which is social network analysis, was used to analyse. Many of the words that students used to describe good doctor were similar. But especially lots of times they used 'patient', 'treatment', 'competence', 'heart' and a word 'patient' showed highest degree centrality. Higher density of network and mean degree centrality were shown in students who experienced clerkship. 'Diagnosis and treatment', 'medical communication', 'attitudes to patients', 'medical knowledge', 'basic competence' these 5 groups were shown in network of students before and after clerkship in common. In the case of students after clerkship, 'lifelong learning ' groups have been added, so were the 6 groups. Considering the fact that social responsibility, professionalism, medical humanities are emphasized in recent medical education, students have lack of perception structure about good doctor, therefore education of this area needs to be strengthened.

Unmanned robot system has become a significant part of network centric warfare. Unnlike the commercial wireless system, however, it is tricky to provide reliable communication in the harsh environment: tactical and military communication. Therefore, it needs to be considered when the base station and mobile has poor communication channel. In this paper, we proposed an efficient operating algorithm for unammned robot system with ensuring communication survivability in the harsh environment. From the simulation, we adopted the SUI channel suitable for domestic mountainous area and open terrain with Rician factor K.

Recently, several researches are focused on the frequency sharing and the liberalization of frequency use for utilizing the limited frequency resources efficiently. In military, as Network Centric Warfare(NCW), which requires significant mutual operability of battle elements and real-time operation speed, has come to the fore front as an important aspect of modern warfare, the methods to manage limited frequency resources in wireless communications environment efficiently has been studied and utilized. In this paper, we propose a Spectrum COP(Common Operation Picture) design suitable for the battlefields of air force. To construct the Spectrum COP of Air Force, we analyze the requirements and design the frequency management system by using EA(Enterprise Architecture) Framework. The simulation results of the proposed design proved the effectiveness by using EADSIM(Extended Air Defense Simulation) of Air Force.
