On the stage of an international trade with well-developed transportation, communication system and proliferation of free trade, global companies who are eager to sustain business growth by cutting cost and pioneering new market are facing a new challenge named "Global Compliance" of business transparency, export and import regulations, and potential international business environment. The purpose of a global compliance is to monitor and regulate a company's trade activities to reduce the risk of transactions that might violate relevant countries' laws, regulations, or standards. After the 911, for strengthening the non-proliferation of the export control goods, UNSCR1540(United Nations Security Council Resolution 1540(2004)) was declared in order to enforce the members to adopt the rules in the resolution into their national laws and regulations. Companies does not realized that they need to get rid of the risks because they underestimate the importance of international security, caused by their careless management. That is why currently the export control program is not fully observed by the most. Lack of awareness for the export control and the poor system of each members could be the reason for this unstable operating status. With this background, this thesis will study on the meaning of export control, schemes for companies to recognize its importance and governmental guideline to support global companies.

Purpose: In this logistics disturbance period, this study conducts research of distribution and logistics firms in Korea. The purpose of this exploratory research is to analyze global competitive capability influence on business performance. And give managerial implications and contribute to academics. Research design, data, and methodology: This research empirically analyzes the relationship between global competitive capability and business performance. As for business performance this research considered non-financial performance and measured with business performance fulfillment. As for antecedent variables, this research measured three global competitive capability constructs; preparation, utilization, intensive capability. And each construct includes two capability concepts. This study used 2,316 executing direct export distribution and logistics industry firmsfrom KOTRA's GCL data. This research used frequency analysis, reliability analysis, correlation analysis, and step-wise regression analysis by SPSS26. Results: The result shows that all the variables except export infra showed statistically significant. As results show, mid/long strategy & global mind of preparation capability, both communication and marketing of utilization capability and market strategy and product/goods/service of intensive capability give a positive influence on business performance fulfillment. Conclusions: Based on the results, this research provide implication for practical management, contribution to academic, and suggestion for feature research.

최근 GPS(Global Positioning System)와 무선통신 기술을 이용하여 화물의 위치정보를 파악하는 것이 용이해지고 있다. 해운물류산업에서는 글로벌화가 가속화됨에 따라 화물을 실은 선박의 입출항 확인, 물류차량의 물류거점별 진입여부 등 화물의 가시성, 추적성, 실시간 정보제공의 필요성이 더욱 커지고 있다. 이러한 위치정보를 무선통신기술을 이용하여 물류주체에게 제공함으로써 공급사슬을 효율적으로 운영하고, 물류비용을 줄일 수 있다. 이전의 논문에서 GPS 데이터를 이용한 소프트웨어적인 방법으로 GPS 기반의 글로벌 위치추적 시스템을 제안한 바 있다. 그러나 이전 시스템에서는 실시간 위치이동 정보를 파악하기에 미흡한 문제점이 있었으며, 경도, 위도 좌표에 따른 글로벌 물류거점 위치를 신속하게 검색 및 조회하는 연구가 미비했었다. 따라서, 이 논문에서는 실시간으로 해운물류 과정의 화물 위치를 파악하고 GPS 좌표에 따른 물류거점을 신속하게 검색할 수 있는 보완된 위치추적 시스템을 제안한다.

Visible light communication (VLC) using LED lamps is suitable for implementing an indoor positioning system in an indoor environment where the global positioning system (GPS) signal does not reach. In this paper, we present an indoor positioning system for mobile robots using a VLC beacon and fuzzy rules. This system consists of an autonomous mobile robot, VLC modules, and device application software. Fuzzy rules are applied to plan the global and local paths along which the mobile robot navigates indoors. The VLC transmitter modules are attached to the wall or the ceiling as beacons to transmit their own location information. The variable pulse position modulation (VPPM) algorithm is used to transmit data, which is a new modulation scheme for VLC providing a dimming control mechanism for flicker-free optical communication. The mobile robot has a receiver module to receive the location information while performing its mission in the environment where VLC transmitters are deployed.

This paper describes a novel global on-chip interconnect scheme, in which a one UI-delayed symbol as well as the current symbol is sent for easing the sensing operation at receiver end. With this approach, the voltage swing on the channel for reliable sensing can be reduced, resulting in performance improvement in terms of power consumption, peak current, and delay spread due to PVT variations, as compared to the conventional repeater insertion schemes. Evaluation for on-chip interconnects having various lengths in a 130 nm CMOS process indicated that the proposed on-chip interconnect scheme achieved a power reduction of up to 71.3%. The peak current during data transmission and the delay spread due to PVT variations were also reduced by as much as 52.1% and 65.3%, respectively.

Network virtualization enables autonomous and heterogeneous Virtual Networks (VNs) to co-exist on a shared physical substrate. In a Network Virtualization Environment (NVE), the fact that individual VNs are underpinned by diverse naming mechanisms brings about an obvious challenge for transparent communication across multiple VN domains due to the complexity of uniquely identifying users. Existing solutions were mainly proposed compatible to Internet paradigm with little consideration of their applications in a virtualized environment. This calls for a scalable and efficient naming framework to enable consistent communication across a large user population (fixed or mobile) hosted by multiple VNs. This paper highlights the underlying technical requirements and presents a scalable Global Naming Framework (GNF), which (1) enables transparent communication across multiple VNs owned by the same or different SPs; (2) supports communication in the presence of dynamics induced from both VN and end users; and (3) greatly reduces the network operational complexity (space and time). The suggested approach is assessed through extensive simulation experiments for a range of network scenarios. The numerical result clearly verifies its effectiveness and scalability which enables its application in a large-scale NVE without significant deployment and management hurdles.
