Supply chains and locational adjustment in the global automotive industry

This paper helps to set the scene for this special issue on automotive restructuring and policy responses. It starts by providing a brief introduction to the different inventory and supply-chain management approaches dominant within the industry at different stages of its evolution, before moving on to outline the spatial implications of these different approaches. The paper then presents a transactions–costs conceptual framework for analysing key features of the auto manufacturing and supply-chain system, using a taxonomy approach. The paper concludes by highlighting the spatial and policy implications for the auto industry which arise from such a transactions–costs analysis. Interestingly, the logic of both a transactions–costs approach and a consideration of knowledge spillovers both point towards the increasing spatial concentration of higher value-added activities. This may have a number of policy implications in terms of the industrial, technology and regional policies required to support and sustain such higher value-added activities. This is also consistent with the view that globalization leads to greater spatial dispersion, as the latter tends to be dominated by lower value-adding activities, with the core locations progressively moving towards higher value-adding activities. Overall, the opposing positive and negative impacts on regional ‘winners’ and ‘losers’ will be more greatly amplified than would previously have been the case. As such, regions benefiting from the immigration of integrated supply-chain networks will tend to maintain their advantageous position in the industry over time. On the downside, regions which lose such supply-chain systems, as seen over the last two decades in many regions in the US, UK and Australia, face a challenging situation, with very limited prospects for redeveloping such systems via policy initiatives.

Energy-Efficient Clustering scheme with Concentric Hierarchy

With the development of the Wireless Sensor Network (WSN) technology, ubiquitous technology comes to the fore as the core technology in the future. In the Wireless Sensor Network, energy efficiency of the whole network is a key problem that has to be solved. Clustering is one of routing techniques to improve energy efficiency. LEACH and LEACH-C are existing techniques focused on optimizing energy efficiency of the network by applying clustering. However, those protocols still have problems. LEACH does not guarantee balanced distribution of cluster heads and communication overhead of LEACH-C is quite heavy. In this paper, therefore, we suggest a new method, “Energy-Efficient Clustering scheme with Concentric Hierarchy (EECCH),” a centralized clustering scheme aimed at overcoming weaknesses of LEACH and LEACH-C both. By drawing circles with the base station as its center, the base station separates network nodes into some levels. Afterward, we let the clusters have different numbers of its member nodes to eliminate inequality in energy dissipation. Through this process, it becomes possible to improve energy efficiency. By using MATLAB, we prove that EECCH gives better performance than some other protocols which also use clustering technique, including LEACH, in the performance evaluation.

Location Choices of Korean MNEs in East Asia: Escaping the Nutcracker

Increasing numbers of free trade and economic partnership agreements have been concluded among many countries in East Asia, and economic integration has progressed rapidly on both a de facto and de jure basis. However, as the authors of this book argue, integration may intensify regional inequalities in East Asia and so this process has attracted much attention of late. Will it actually succeed in achieving greater economic growth or will it in fact cause growing regional disparity?

A Study of Advanced Hybrid Execution Using Reverse Traversal

As software analysis techniques have been developed, lots of software analysis tools and anti-malware programs now can easily detect various kinds of malware. However, techniques for avoiding software analysis are also being developed. Polymorphic malware and obfuscated malware use those kinds of techniques, and they cause enormous damage to computer systems all over the world. In this paper, therefore, we suggest advanced hybrid execution using reverse traversal to examine advanced malware. The method we suggest reads in the whole program, creates control flow graph, and traces all the execution paths reversely, so that infeasible paths can also be detected. By traversing the whole execution paths, including infeasible paths, we can sense hidden vulnerabilities. Although we anticipate huge overhead when tracing all the execution paths, multi-core processing is expected to alleviate the overhead.

Theories on FDI and the Behavior of MNEs in East Asia

Covering a wide range of aspects surrounding economic integration in East Asia, this well-researched text will appeal to undergraduate and postgraduate students of development studies, regional economics and Asian studies. It will be of particular value to those on courses concerned with economic and regional integration.
