This paper applied a VAR model to analyze the effects of RMB exchange rate brought to processing trade, non-processing trade and FDI. Then we can get the results that the appreciation of RMB could not solve the problem of US trade deficit. It is more likely that the appreciation just can transfer the trade imbalance to other country with US, which could not radically solve the economic problems of US. Also this paper find that the data of service trade is surplus while the main goods deficit was occur in advanced technology product, especially in the information & communications trade And US has real advantage in these industries, so the situation will be changed if US decreased the barrier in these industries. In that way, the imbalance situation should be greatly reduced.

The terms electronic trade, electronic trading and electronic commerce are often used interchangeably, and refer to trading transactions conducted using electronic media. Electronic trade is business-to-business transactions in an industrial context, while electronic commerce refers to retailing and the consumer sector as well as mass marketing. The Electronic trade process is defined as a flow of information (documents) exchanged between enterprises and trade-related firms (shipping companies, foreign exchange banks, forwarders, etc.) in the course of implementing a series of export and import procedures. Electronic trading systems exploit information technology to improve the efficiency of communications and/or to alter the nature of inter-organizational transactions. Many studies exist about the adoption of inter-organizational systems (IOS) and electronic data interchange (EDI), but few focus on electronic trade. The literature on exporting companies's electronic trade adoption and implementation, although extensive, consists mainly of exploratory studies focusing on technological characteristics such as barriers, benefits and usage. The purpose of this study is to broaden this perspective by investigating the environmental, organizational and technological drivers of business-to-business e-commerce adoption.

The purpose of this article is to study on the electronic bill of lading in the electronic trade era. The term 'electronic trade' means all or part of any such trade as implemented by means of apparatus having the information processing capability, such as a computer, and networks of information and communications. The introduction of an electronic bill of lading has long been considered essential by the members of the international trading community as a key means of reducing its costly reliance on paper.

Nowadaty, To keep pace with the mass transportation carried out by vessels in the international trade, the Korean government is trying to make a rapid progress to be a higher ranked shipping country to the world through the shipping increase. For the effective management of international trade by vessels and the safe operation of vessels, it is indispensable for ships radio communication to be effective and smooth. Therefore, to enhance the efficiency of ships radio communication is one of the primary factors to be solved for the econimics of shipping management. The reserch area is not only limited to the ships radio communication on the North Pacific Ocean but limited to the ships radio communication which is one of the chiefest methods of communications. From the research for the efficient methods of ships radio communication, the following results are obtained. (1) The operator on ships radio communication should have the knowledge of specific know-how and wide experience in the operation of ships radio communications. (2) The operator should abopt the radio propagation prediction made by the Ministry of Communications to use the best ionosphere reflection in the short wave communications. (3) The increase the radio officer of 1 to 2 in order to contrive the safety at sea and to keep the ships radio communication fare low. (4) The owner should pay their attentions to the education and employment of radio officer. (5) The authorities concerned on the ships radio communication should estabilish the effective and consistent policy for the ships radio officers.

Information and communication technology (ICT) is one of the primary zones that stimulates economic development in today's globalized world. It promotes technological developments in worldwide communication and manufacturing systems, as well as economic growth and development. Many economic activities, such as international trade and foreign direct investment, rely heavily on contemporary information and communications technologies (FDI). The goal of this study is to look at the dynamic relationship between FDI, ICT, trade openness, and economic growth in the context of BRICS countries from 2000 to 2018, with Gross Domestic Product as the dependent variable and Telephone subscriptions, Mobile subscriptions, Broadband subscriptions, Internet subscribers, Secure internet servers, Trade, and Foreign direct investment as the independent variables.Two variables are used as proxies to manage the macroeconomic environment, while five variables are used as proxies for ICT infrastructures. The outcomes of this study are analyzed using Generalized Methods of Movements (GMM). According to this study, ICT has a positive impact on the economic growth of a few countries. Trade openness and foreign direct investment, on the other hand, have a negative impact on economic growth. As growing countries, the BRICS must participate in economic reform and liberalization measures. This report suggests policy proposals for improving ICT standards, focusing especially on economic growth, trade openness, and increasing foreign investment in the BRICS countries.

본 연구에서는 한 중 IT산업의 기업 및 경쟁력 분석, 수출입구조를 통해 전반적인 무역의 흐름을 알아보고 정보통신기기 분야인 통신기기, 정보기기, 방송기기, 부품 등 4개 분야에 대해 무역집중도(Trade Intensity), 현시비교우위지수(Revealed Comparative Advantage), Grubel-Lloyd 지수, 불변시장점유율(Constant Market Share) 등으로 한 중 무역구조를 분석하였는데 그 결과는 다음과 같다. 첫째, 한국은 2004년 이후 3개 기업이 글로벌 500대 기업 리스트에 등재되어 왔으나 중국기업들이 평균 2.25개로 한국을 바짝 쫓아오는 상황에 직면해 있다. 둘째, 무역집중도 지수 분석결과 2002년보다 2007년에 4.57% 증가하여 한 중 간 통신기기에 관한 교역의 긴밀도가 높아지고 있음을 알 수 있었다. 셋째, 현시비교우위지수(Revealed Comparative Advantage)와 Grubel-Lloyd 지수의 분석결과 한국 정보통신기기는 비교열위에 있지만 수출입 구조에서는 흑자를 내고 있다. 넷째, 최근 들어 중국 수입시장에서 상당수 정보통신기기 제품의 시장점유율은 경쟁력과 상품공급구조의 변동으로 시장점유율이 하락하였다. 현재 한 중 정보통신기기 분야의 무역구조 변화와 중국수입시장에서 시장점유율 하락의 어려움을 국내 IT산업이 한 단계 도약할 수 있는 계기로 삼아야 할 것이다.

With the rapid development of information and communications technology, the construction of efficient, reliable, and safe Internet of Things (IoT) is an inevitable trend in order to meet high-quality demands for the forthcoming 6G communications. In this paper, we study a secure intelligent reflecting surface (IRS)-assisted IoT system where malicious eavesdropper trying to sniff out the desired information from the transmission links between the IRS and legitimate IoT devices. We discuss the system overall performance and propose a hybrid resource allocation scheme for maximizing the secrecy capacity and secrecy energy efficiency. In order to achieve the trade-off between transmission reliability, communication security, and energy efficiency, we develop a quantum-inspired marine predator algorithm (QMPA) for realizing rational configuration of system resources and prevent from eavesdropping. Simulation results demonstrate the superiority of the QMPA over other strategies. It is also indicated that proper IRS deployment and power allocation are beneficial for the enhancement of system overall capacity.

기존의 컴퓨팅환경에서 유비쿼터스 컴퓨팅 환경으로의 전환이 이루어지면서 사용자는 언제 어디서나 네트워크에 연결될 수 있다. 이는 역으로 말하면 언제 어디서나 사용자의 정보가 네트워크에 유출될 수도 있다는 것을 의미한다. 컴퓨팅 환경에서 보안성과 편리성의 추구는 서로 상반되는 Trade-off 문제이다. 이 논문에서는 오토노믹 컴퓨팅(Autonomic Computing)의 개념 [1, 2］을 이용, 정해진 개인정보 보호정책(Privacy Policy)에 기반 하여 개인정보를 보호하고 서비스 사용자의 환경 변화에 대안 상황인지(Situation-Aware)를 통해 유연한 개인정보 보호정책을 적용할 수 있는 아키텍쳐를 제안함으로서 보안성(개인정보보호)과 편리성(사용자 개입의 최소화)의 문제를 다루어보았다.
