Location management is difficult in ad hoc networks due to many features such as the lack of a wired infrastructure, the scarce energy, memory and processing capabilities of nodes, and nodes’ movement which leads to a dynamic topology. These characteristics make the location management schemes designed for mobile cellular networks inefficient for ad hoc networks. New solutions for location management have therefore been proposed in the literature in the recent past. In this paper, a taxonomy of location management strategies is presented; some of the more interesting approaches proposed in the literature are critically discussed, highlighting their advantages and disadvantages.

본 논문의 주 목적은 한국의 대중국 해외직접투자의 지리적 변화에 대한 근본적인 원인을 밝히고자 하는데 있다. 특히 1990년대 후반 이후 대중국 투자전략 전환으로 인한 투자 업종 및 입지의 변화는 한국 투자기업이 기업특유 우위(ownership-specific advantages), 내부화우위(internalization advantages) 및 입지우위(locational advantages)에 이론적 기반을 둔 것이 아니라, 시장, 제도 및 기술을 중심으로 한국과 중국 양 국가의 수요가 접합되는 지점의 변화, 즉 통합적 전략의 변화에 기반을 두고 있다고 주장한다. 다시 말해, 1990년대 후반 이후 한국 대중국 직접투자 입지 변화는 2000년 이후 중국시장구조의 변화, 투자유입에 대한 중국의 제도적 변화, 한국기업의 기술역량 제고에 기인한다는 것이다. 이와 더불어 본 논문은 2000년 이후 급속히 증가하고 있는 CDMA 이동통신 투자경험을 사례로 한국 대중국 직접투자에 대한 시상, 제도 및 기술의 입지효과를 밝히고자 하였다.

This paper proposes an ultrasonic location system based on the spread spectrum principle. Compared with the existing ultrasonic location systems, the proposed system combines the spread spectrum and amplitude modulation principles. As a result, the proposed ultrasonic location system is advantageous in that it can improve positioning accuracy and detection sensitivity by the spread spectrum principle, it simplifies transmitter and receiver circuits by the amplitude modulation, and it is easy to upgrade its performance by the software functionalities. The advantages and performance of the proposed location system are demonstrated by experiments.

The advantages of implementing a virtual channel can be derived from the notion of the 'death of distance' that would result from electronic commerce. According to this view, the internet was going to make distance irrelevant, in that firms would no longer need to establish a physical presence in a geographical location in order to do business there. However, on-line firms selling physical products could take advantages of presence in the related off-line(brick and mortar) industrial area. This paper developed a conceptual framework that highlights the various types of synergies by location on-line businesses in the related off-line industrial area. Using data from 96 on-line ventures selling physical products, factor analysis was used to figuring out six synergies including improved customer trust, value-added service, cost savings, personnel and organizational efficiency, sharing products and customer information, relationship with suppliers, and relationship with local government. The six empirically derived critical synergy factors were then used to examine how they improve performance of the on-line ventures measured by Balanced Scorecard(BSC). According to lthe results, we concluded that the on-line firms selling physical products can take advantages of presence in the related off-line industrial area.

This study identified types of online retail internationalization in the fast-fashion context and proposed driving factors of retailers' choices in online-based market entry following the logic of the Uppsala model and the eclectic theory. In particular, this study proposes three types of online-based internationalization: 1) entering a host market with a physical store first, and then expanding with an online store, 2) entering a foreign market with an online store, then expanding to physical stores, and 3) entering only with an online business. In addition, this study investigated the causal factors, ownership-specific and location advantages, that influence the choice of the type of developmental process of online-based internationalization. To develop theoretical and managerial insights into the issue researched, this study employed a qualitative research design involving case studies of three European fast-fashion retailers, H&M, TOPSHOP, and ASOS. This study suggested that fast-fashion retailers that enter a host market with high ownership-specific advantages are likely to choose to enter the market with physical stores and then expand with online stores. On the other hand, when faced with uncertainties attributable to low ownership-specific or location advantages, fast-fashion retailers are likely to choose to enter with an online store first and then expand with physical stores as conditions change. Consequently, this study provides a better understanding for fast-fashion retailers who are willing to expand their businesses to foreign markets via online stores.

Our studies diagnose insulation degradation using the method of computer sensing system, which has the advantages of PD(partial discharge) and AE(acoustic emission) sensing system. To use advantages of these two methods can be used effectively to search for treeing location and PD in some materials. In analysis method of degradation, using statically operator such as the center of gravity (G), the gradient of the discharge distribution(C), we have analyzed for the prediction of life which we can be obtained the time, occurred of many pulse of small discharge amplitude.

This paper analyzes the comparative advantages and development prospects of the China (Anhui) Pilot Free Trade Zone. Based on a SWOT analysis method, this study finds that the Anhui Pilot Free Trade Zone has a set of comparative advantages, including location advantage, rich resources, industrial transformation and new industries, technological innovation capabilities, new patterns for development, and policy support. In recent years, by leveraging its key resources, Anhui Province has been committed to developing an open economy. Furthermore, its economic vitality has increased significantly under preferential policies such as the Belt and Road Initiative, the China-Europe International Freight Shuttle, and the Yangtze River Economic Belt Development Plan. As a result, the total foreign trade has continued to grow. The findings of this study highlight that the comparative advantages are of great significance to the development of the Anhui Pilot Free Trade Zone, which helped expand the scope and openness of the regional economy and foreign investment. However, to achieve the development objectives of the Anhui Pilot Free Trade Zone as planned, these comparative advantages must be developed and converted into a set of sustainable competitive advantages for the regional economy. Therefore, a few development suggestions are put forward.

본 논문은 한국 현지에 진출하여 직접 경영활동을 수행하고 있는 중국 제조업 분야 기업들을 대상으로 대한국 해외직접투자 결정요인을 규명하는 것이다. 결정요인을 구성하고 있는 변수로는 선행연구를 통해서 중국기업들의 경쟁우위요인과 한국의 입지우위요인으로 선정하였다. 경쟁우위요인은 다시 3분되는데, 중국기업의 독점우위요인, 본사의 자회사에 대한 지원 필요성, 그리고 효율성 추구 동기 등이다. 한국의 입지우위요인은 한국의 일반 환경, 중국 자회사들의 한국내 자원의 이용 필요성, 시장과 원자재 조달 동기 등이며, 종속 변수로는 중국 기업들의 투자형태로서 단독투자와 합작투자로 분류하였다. 이들 간의 원인 관계를 실증적으로 분석하기 위해 구조방정식모델링 기법을 사용하였다. 분석 절차를 요약하면, 선행연구를 통해 문헌분석을 실행하고 이를 토대로 연구가설을 설립한 후 이를 검증하기 위한 실증분석을 실시하는 것이다. 즉, SPSS 15.0 for windows를 이용하여 상관분석, 신뢰성 타당성 분석을 실행하였고, 최종적으로 구조 방정식 모델링을 통한 경로분석은 AMOS 11.0 for windows 통계프로그램을 활용하였다.

In order to effectively relieve the traffic pressure of the city, ensure the smooth flow of freight and promote the development of the logistics industry, the selection of appropriate port logistics location is the basis of giving full play to the port logistics function. In order to better realize the selection of port logistics, this paper adopts the entropy weight method to set up a multi-dimensional evaluation index, and constructs the evaluation model of port logistics location. Then through the actual case, from the environmental dimension and economic competition dimension to make choices and analysis. The results show that port d has the largest logistics competitiveness and the highest relative proximity among the three indicators of hinterland city economic activity, hinterland economic structure, and port operation capacity of different port logistics locations, which has absolute advantages. It is hoped that the research results can provide a reference for the multi-dimensional selection of port logistics site selections.
