통행발생은 4단계 모형의 처음 단계로 전체수요예측에 상당한 영향을 미치게 되므로 정확성이 무엇보다 필요한 단계라 할 수 있다. 현재 통행발생모형으로 도시교통 및 SOC시설 등의 계획에 널리 사용되고 있는 것은 선형회귀모형이며, 각종 사회경제지표와 통행발생량의 관계가 선형임을 전제로 한다. 하지만 급격한 도시개발이나 도시계획구조가 변경되었을 때 통행량을 추정하기 위한 사회경제지표 자료가 부족하여 추정된 통행량의 오차가 많을 수 있다. 이에 본 연구는 일반적으로 널리 사용되는 사회경제지표를 선형이란 가정을 하지 않고, 다양한 존의 특성을 반영할 수 있는 변수에 대한 시장분할을 토대로 새로운 유형별 통행발생모형을 개발하고자 한다. 본 연구에서는 교통수요예측의 처음 단계인 통행발생 모형의 예측력을 개선하기 위하여 존의 다양한 특성(토지이용, 사회경제적 등)을 고려하였다. 예측력 개선을 위한 시장분할 방법론으로는 통행 발생률을 기반으로 한 Data Mining(CART)방법과 회귀분석을 이용하였다. 연구의 결과를 살펴보면, 첫째, CART분석을 활용한 존 특성 분석결과, 유출통행은 사회경제적 요인(남녀상대비중, 연령대(22~29세))에 영향을 받고 있으며, 유입통행은 토지이용 요인(업무시설상대비중), 사회경제적 요인(3차 종사자상대비중)으로 나타났다. 둘째, 유형별 모형개발 결과 통행발생 계수 값은 유출의 경우 0.977~0.987(통행/인)이며, 유입의 경우 0.692~3.256(통행/인)로 나타나 유형구분이 필요한 것으로 나타났다. 셋째, 실측검증을 수행하였으며, 유출 및 유입의 경우 기존 모형보다 적합도가 높아진 것을 알 수 있다. 따라서 본 연구에서 개발한 유형별 통행발생모형이 기존 연구보다 우수한 것을 알 수 있었다.

광양만권 경제자유구역은 2003년 함께 지정되었던 인천, 부산 경제자유구역 등에 비해서 지리적, 인지도, 사회간접자본 등의 측면에서 불리한 여건에 있다. 물론 정부, 지자체, 광양만권 경제자유구역청 등은 변화시키기 어려운 우리사회의 여건 속에서 외국인투자 유치를 위한 최선의 방안을 모색하고, 이를 실행하기 위한 각종 제도의 정비, 환경조성, 운영전략 등 외국인 투자유치를 위해 노력하고 있지만 이에 대한 실적은 부족한 실정이다. 광양만권 경제자유구역이 성공하기 위해서는 경제자유구역을 거점으로 아시아와 세계를 상대로 하는 비즈니스를 구상하고, 수행하는 많은 외국인투자기업을 유치하기 위한 운영전략이 필요하다. 그러나 아직까지 광양만권 경제자유구역 내 이러한 양질의 외국인투자기업을 유치하기 위한 광양만권 경제자유구역만의 차별화 된 운영전략이 부족한 것으로 평가되고 있다. 광양만권 경제자유구역의 외국인 투자유치 활성화를 위한 마케팅 믹스 전략을 제시하면 다음과 같다. 첫째, 제품(product)전략으로 주변 특성과 연계된 클러스터를 구축해야 한다. 둘째, 가격(price)전략 측면에서는 탄력적인 인센티브와 맞춤형 인센티브, 현물 및 현금보조금 제도의 비중을 높여야 한다. 셋째, 촉진(promotion)전략 측면에서는 전문능력 및 외국어능력을 겸비한 인력양성과 수요자 위주의 환경을 조성해야 한다. 넷째, 유통(place) 전략 측면에서는 광양만권 경제자유구역청의 독립화 및 전문화가 구축되어야 한다.

There are disputes for oil and gas development between China and Japan in the East China Sea. These involve the area where China is already carrying out activities of oil and gas development and where Japan is proclaiming its EEZ. China insists that the Chinese activities on oil and gas development area are being carried out within the Chinese jurisdictional waters even if the median line principle of Japanese proclamation is applied in delimitation. Indeed, the permit for Japanese development is causing disputes between China and Japan because its permit allows development in the waters adjacent to Chinese development area. h the event, the core of this dispute around the oil and gas field in the East China Sea relates to issues of maritime boundary delimitation and issues of resources acquisition with both states. Chinese policy on oil and gas development is to first consider development issues in accordance with a median line principle where waters toward to China from the median line should be developed by China and the area toward Japan from the median line within the Chinese continental shelf should be jointly developed. However, the Japanese position is that the East China Sea should be jointly developed, and Japan hopes to eventually convince China to accept its median line delimitation. With on-going development of such issues, Korea should establish a strategy of negotiation based on analyses of resource distributional conditions and other strategic factors in the Korean delimitation area. In particular, Korea should prepare and make the best use of joint development zone established in an agreement between the ROK and Japan concerning the development of the southern part of continental shelf adjacent to both states.

This study aims to assess the attraction of foreign direct investment in Vietnamese economic zones (including industrial zones and economic zones). The main research method used are synthesis and comparison analysis based on the data collected from the surveyed group comprising of enterprises operating in the economic zones in the Middle (Chu Lai, Nhon Hoi, Dung Quat) and the Southern (the largest island: Phu Quoc). After conducting surveys, research results show that there is a difference between the assessment and the level to meet the requirements of investors with business environment, expressed through the following criteria: (1) the infrastructure; (2) quality of public services; (3) preferential policies; (4) labor; (5) market; and (6) social services. Based on the assessment of the identified criteria, this paper had suggested six number of recommendations to promote the role of attracting foreign direct investment capital into the economic zones in Vietnam: (1) implementing the "one-stop-shop" policy; (2) continuing to improve the infrastructure of economic zones; (3) prevent and ensure the security of economic zones; (4) implementing vocational training activities to improve quality of human resources; (5) development of supporting industries; (6) raising the quality of capital invested in the economic zone.

This study is intended for the development of urgent facing strategies for the designation of a CFZ(Customs Free Zone) in Incheon city. First, it analyzes the current status of the Incheon CFZ. Next, it suggests several strategies for successfully growing the CFZ of Incheon City. Finally, it develops and proposes a method for establishing an integrated management system for the effective management of the CFZ. The key findings of this study are as follows: First, the CFZ should provide state-of-the-art movement of port logistics, create new added value caused by the movement of logistics, and provide other public support. The Incheon CFZ should be developed in three stages: an inducement stage in 2002-2005, a growth stage in 2005-2008, and an implementation stage in 2008-2011. Second, The parties responsible for the management of the CFZ would be as follows: for the port area, the Ministry of Maritime and Fisheries; for the back space of CFZ, Incheon City; and for port management, port management companies. However, a committee for CFZ management is strongly suggested for the improved efficiency and effectiveness of CFZ management. Furthermore, additional regulations ensuring the role of local government will likely be necessary for the sucessful designation and sustainable management of the CFZ. Third, For the creation of additional revenue, reformation of the current laws of the CFZ are recommended in the area of business administration. Fourth, A strategic marketing plan that supports the successful management of the companies of the CFZ will be a key component in the success of the CFZ. Thus, the new marketing plan should be developed in the near future based on case studies of other CFZs. Fifth A method for an integrated CFZ management system was developed and suggested for the comprehensive and transparent management of port logistics.

Global firms are seeking to implement their global logistics strategies in two ways: the use of centralized inventories and/or postponement of final assembly. These strategies stress the importance of regional logistics centers. In most cases, regional logistics centers are located in or near ports so that changing demands can be met with economy, reliability and flexibility, The port can profit not only from the activities of logistics center itself, but also the increasing flow of cargo through the logistics center. A number of ports respond to this trend by shifting their emphasis from traditional cargo-handling services to value-added services. This paper presents guidelines drawn from the best practices of ports to be successful logistics centers to provide many aspects of value-added logistics services. These include: Effective Planning and Development of Logistics Centers; Institutional Incentive Scheme; Development of Free Trade Zones; Financing Infrastructure related to Logistics Centers; Developing Logistics Service Providers and Logistics Professionals; Development of Information Technology; and Regulatory and Administrative Issues. These guidelines will help managers of ports and policy makers of governments in the East Asian region learn to recognize, analyze and adopt the best practices for use.

Korea classified into a development country when UNFCCC was concluded in 1995. So Korea doesn't have a GHG reduction duty until 2012. As the UNFCCC is strengthened, recently there is a growing interest in renewable energy and energy usage efficiency improvement for reducing GHG emission. It is associated with CES and renewable energy. CES is a total energy (heat, cooling and power)supplier in aggregated demand zone like a hotel, building, hospital and redevelopment district using CHP and it improves energy usage efficiency. At present, renewable energy is needed for GHG reduction duty but renewable energy doesn't have economic feasibility. So renewable energy is needed various support system to popularize which is a FIT and RPS. Especially RPS is carrying out instead of FIT in many advanced country and it will be inroduced in Korea. RPS is a duty which electricity service provider must guarantee renewable energy as much as specific ratio of total capacity. Therefore this study conducts an economic feasibility estimation of CES considering renewable energy when RPS will introduced in the future.
