Many megacities are exposed to natural hazards such as earthquakes, and when located in coastal regions, are also vulnerable to hurricanes and tsunamis. The physical infrastructures of transportation systems in megacities have become so complicated that very few organizations can understand their response to extreme events such as earthquakes and can effectively mitigate subsequent economic downfalls. The technological advances made in recent years to support these complex systems have not grown as fast as the rapid demand on these systems burdened by population shift toward megacities. The objective of this paper is to examine the risks imposed on and recoveries of transportation systems in megacities as the result of extreme events such as an earthquake. First, the physical damage to transportation infrastructure, loss of the transportation system performance, and the corresponding economic loss from disruptions to passenger and freight traffic is evaluated. Then, traffic flows are re-routed to reduce vehicles' delay due to earthquakes using a microscopic traffic flow simulator with an optimization model and macroscopic terminal simulator. Finally, the economic impact of the earthquake is estimated nationwide. Southern California is regarded as the region of study. The results demonstrate the effectiveness of the integrated model and provide what and how to prepare innovative resilience policies of urban infrastructure for a natural disaster occurrence.

Since the first oil embargo (1973), there have been developed many different types of energy-economy interaction models based upon various aspects of energy impact mechanism. We will propose to develop an integrated energy-economy interaction analysis system for less developed countries' energy policy analysis, especially for investment analysis toward constructing energy-saving industry infrastructure ; which is based on the motivation of combined energy models by John P. Weyant. This modeling system can cover the economic growth, inter-industry transactions including production features, and process analysis of energy sector in the total network scheme of general equilibrium, so that it can give many political implications as well as the modeling concept to be used for analyzing various political issues and making decisions related to national energy environment.

This research analyzed on the future energy society of Korea in 2030 using system thinking approach. Key uncertainty factors determining the future energy society were analyzed in a multi disciplinary view point such as politics, economy, society, ecology and technology. Three causal loop diagrams for the future energy system in Korea and related policy leverages were shown as well. 'Global economic trends', 'change of industrial structure' and 'energy price' were identified as key uncertainty factors determining the Korean energy future. Three causal loop diagrams named as 'rate of energy self－sufficiency and alternative energy production', 'economic activity and energy demand' and 'Excavation of new growth engines' were developed. We integrated those causal loop diagrams into one to understand the entire energy system of the future, proposed three strategic scenarios(optimistic, pessimistic and most likely) and discussed implications and limits of this research.

Multi-scale representations are effective in characterising the time-frequency characteristics of financial return series. They have the capability to reveal the properties not evident with typical time domain analysis. Given the aforesaid, this study derives crucial insights from multi scale analysis to investigate the co-movements between Indian and emerging Asian equity markets using wavelet correlation and wavelet coherence measures. It is reported that the Indian equity market is strongly integrated with Asian equity markets at lower frequency scales and relatively less blended at higher frequencies. On the other hand the results from cross correlations suggest that the lead-lag relationship becomes substantial as we turn to lower frequency scales and finally, wavelet coherence demonstrates that this correlation eventually grows strong in the interim of the crises period at lower frequency scales. Overall the findings are relevant and have strong policy and practical implications.

Climate technology applied to address climate change requires a comprehensive review such as environmental and social acceptability in addition to economic feasibility. Not only mitigation and adaptation technologies, but also integration of climate technologies into a business model with other relevant technologies including ICT, finance, and policy instruments could enhance technical, economic, and environmental performances to respond to climate changes. However, many climate projects (and business models) are currently not designed to consider adequately complex climate?related issues. In addition, there is a lack of research on assessment systems that can comprehensively evaluate business feasibility of such models. In this study, we developed a system consisting of nine major indicators in four fields to assess climate technology-based business models. Each indicator was weighed using the analytic hierarchy process (AHP) for systematic assessment of business models. The process can be utilized as a tool to guide improvement of climate technology business models.

2005년 국내 중고차 시장은 신차 거래규모의 1.5배인 약 170만대가 거래되었으며 직간접적인 금액도 10조원에 이르는 시장규모이다. 이와 같은 중고차 시장은 2005년 인터넷쇼핑몰의 거래규모와 거의 동일한 시장규모이다. 국내 중고차의 공급량은 신차 생산량의 증가와 기술력 향상으로 자동차의 수명이 길어짐에 따라 더욱 증가할 것이다. 본 연구에서는 이와 같이 증가하는 중고차 공급과 중고차 수출 감소를 해결하기 위한 중고차 수출물류혁신방안을 제시하고자 한다. 기존 중고차 수출관련 연구 등에서는 수출 전용부두 조성, 통관지원과 같이 중고차 수출물류에 있어서 부분적인 검토가 이뤄졌으나, 본 연구에서는 국내 중고차 유통과 수출부분을 모두 고려한 수출물류 프로세스측면에서 분석과 방안을 제시하였다. 또한 국내 중고차 수출관련업체를 대상으로 설문 및 면담조사를 실시하여 중고차 수출물류 활성화를 위한 현실적인 대안 및 정책방안을 모색하였다. 중고차 수출물류혁신방안으로는 수출물류 프로세스 개선을 위한 수출물류통합시스템 구축과 수출활성화를 위한 전초기지인 수출물류단지 조성에 대하여 제시하였다. 인천항에 중고차 수출활성화를 통한 경제적 효과를 분석한 결과 관련업체의 수익증가 270억원, 수출물류단지 조성으로 인한 부가가치 효과 3.4천억원, 고용효과 2,200명으로 추정된다. 그러나 이와 같은 수출물류혁신방안이 추진되기 위해서는 일관된 정책이 추진되어야 한다. 중고차 수출활성화를 위해 현재의 문제점만을 개선하는 근시안적인 정책이 아니라 지속적으로 국제시장에서 우리나라 중고차가 경쟁력을 확보할 수 있는 중장기적인 중고차관련정책이 필요하다. 이에 본 연구의 목적은 수출물류통합시스템구축과 수출물류단지 조성을 위한 정책방안을 제시하고자 한다.

이 연구는 세계화라는 맥락에서 신자유주의, 사회복지 축소, 제3의 길이라는 상호관련된 주제들을 분석하고 있다. 통합된 세계경제체제에서 이루어지는 자유화, 규제 철폐, 민영화로 정의되는 신자유주의적 세계질서는 국제 금융자본의 세계질서를 강화함으로써 개별 국민국가의 자율성과 사회복지적 개입, 그리고 민주주의 원칙을 불가능하게 만들고 사회복지정책을 경제정책에 예속시킨다. 더욱이 서구 복지 선진국들은 복지와 성장, 축적과 정당화라는 상충적 요소의 공존이 필연적으로 위기를 만들어내며, 이 위기는 어느 한쪽을 완전히 포기하지 않고는 해결되지 않는다는 분석이 있다. '생산적 복지', '노동하는 복지'를 강조하는 제3의 길은 신자유주의의 변형에 지나지 않는다는 비난에도 불구하고 영국과 독일 등의 좌파 정부들이 채택하고 있는 노선이다. 그러나 세계화를 배경으로 한 우리나라의 경제위기는 대량의 실업과 빈곤의 양극화를 심화시켰고 빈약한 사회복지는 이를 더욱 악화시키고 있다. 유럽과는 상이한 역사적 과정과 정치경제적 환경을 배경으로 하고 있는 우리나라에서 제3의 길에 대한 논의와 성급한 복지위기 논쟁은 결코 수용될 수 없을 것이다.

A worldwide trend of permitting system for industrial installation to achieve a high level of protection of the environment has been moved from single media to multimedia in approach. The Council of the European Community issued the Directive 96/61/EC, the IPPC Directive, concerning integrated pollution prevention and control in 1996. The IPPC Directive is one of the most ambitious legal measures that the European Union (EU) has initiated with a view to applying the prevention principle for industrial activities. The IPPC aims to achieve the integrated prevention and reduction of environmental pollution emitted by those industrial installations with a higher potential of emissions to the environment. Organization for Economic Cooperation and Development (OECD) recommended on Environmental Performance Reviews of Korea in 2006 that IPPC permitting concept should be considered for large stationary sources at the national and regional levels. Any Korean law doesn't provide for integrated pollution control with a single process covering all pollution from economic activities. However, one exception might be the "environmentally-friendly companies" certification scheme, introduced in 1995, in which participants agree to meet targets beyond the legal emission limit values in exchange for government technical and financial support to operate environmental management systems. The other exception might be Environmental impact assessment (EIA) of projects, in 1977, which has been strengthened and reinforced to be more preventive through development of the prior environmental review system (PERS) in 1999. The aim of this work is to introduce the contents of IPPC Directive at the viewpoint of Korea policy and to survey the integrated approaching concept of Environmentally-Friendly Companies (EFC) Certification Scheme and EIA policy of Korea. The study will be helpful in the future to prepare the infrastructure of integrated permitting system and to enforce the integrated permit which the authorities of local government issues on industrial activities. It can be said that the data calculated through both EFC Certification Scheme and EIA will be discussed as worthful information to determine Korean BAT reference notes for integrated permitting process.

The synchronization of production-delivery artivities is one of crucial factors to get competitive collaboration benefits between the manufacturer and the retailor(s). There were several researches to study on He optimal delivery policy to minimize the total cost of integrated system of both manufacturer and retailor(s). In this research, we investigate the joint optimal shipment policy in case that a manufacturer produces multiple products sharing a single production facility in the manufacturer side and retailor(s) deploys JIT delivery pattern with equal-size shipment policy. We formulate this problem as a form of 'Common Cycle Approach' in classical ELSP (Economic Lot Scheduling Problem) and provide simple optimal solution procedure.
