This paper aims to examine the contribution that the ERVET System, composed of ERVET and real service centers, has made to both governing and enhancing regional innovation system in Emilia Romagna, Italy. ERVET and real service centers both establish and perform plans for regional development and innovation. But they also try to provide varieties of real services for local firms, mostly small and medium-sized firms. Attempting to promote innovation networks between industries, universities and administrative bodies, the ERVET System has become a core intermediary agency of Emilia Romagna in both governing regional innovation system and enhancing regional innovation capabilities. Based on the case of the ERVET System, we propose a policy recommendation. As local governments in Korea have still been less autonomous but hierarchical, it would be difficult for them to make the decision effectively on regional innovation and development initiatives. In this context, we suggest that regional development agencies need to be established on the basis of benchmarking advanced cases in Europe and North America such as the ERVET System.

The transmission networks are not perfect conductors and a percentage of the power generated is therefore lost before it reaches the loads. This network loss contributes to the cost of suppling power to consumers, and must be considered if the most efficient dispatch and location of generators and loads is to be achieved. In this paper, we propose an approximate calculation of marginal loss factors to analyze characteristics of regional transmission loss. These static marginal loss factors are approximately calculated based on the KEPCO's expected summer peak load data of year 2000.

Green tourism is a stay-flow activity between people in urban and rural area, using a natural view, tradition, and life in agricultural area. And green tourism provides rest, recreation, and new experience fur people living in urban area as well as opportunities to increase income for people in rural area. In recently, amenity is rapidly rising as a main factor fur a regional competitiveness. Boseong county shows a typical agriculture industrial structure with a weak independent base, but has a beautiful tea fields in full seasons. Boseong county is making an effort to activate the regional economy, but the result fall short of one's expectation. Several methods to activate the green tourism of Boseong county are as follows: i) introduction of specialized theme relating Boseong green tea; ii) provision of information regarding tourist resort and development of experience-program related to green tea business; iii) establishment of a sales network of products through accommodations in private houses; iv) establishment of networks among regions to achieve systematic sales of tourist experience, accommodations in private houses, and local speciality simultaneously.

Large-scale failures resulting from natural disasters or intentional attacks are now causing serious concerns for communication network infrastructure, as the impact of large-scale network connection disruptions may cause significant costs for service providers and subscribers. In this paper, we propose a new framework for the analysis and prevention of network service disruptions in large-scale failure scenarios. We build dynamic deterministic and probabilistic models to capture the impact of regional failures as they evolve with time. A probabilistic failure model is proposed based on wave energy behaviour. Then, we develop a novel approach for preventive protection of the network in such probabilistic large-scale failure scenarios. We show that our method significantly improves uninterrupted delivery of data in the network and reduces service disruption times in large-scale regional failure scenarios.

The transmission networks are not perfect conductors and a percentage of the power generated is therefore lost before it reaches the loads. This network loss contributes to the cost of suppling power to consumers, and must be considered if the most efficient dispatch and location of generators and loads are to be achieved. In this paper, marginal loss factors are calculated for 12 load cases that represent the impact of marginal network losses on nodal prices at the transmission network connection points. Based on comparison analysis of marginal loss factors for 12 loaf cases, we can find the regional MLF characteristics in KOREA.

This paper introduced a novel railway system, Automatic Train Protection and Block (ATPB) briefly, which is proposed to improve the efficiency of existing regional train lines with low cost in Japan. The biggest superiority of ATPB system is a great use of universal and mature technologies, such as GPS and regular mobile telephone networks, so that there is nearly no increment of trackside equipments in the reconstruction. Then in order to guarantee the system safety, a formal model of ATPB is established and analyzed by formal method VDM++. Firstly, the specification is specified by VDM++ formally without ambiguity. Secondly, its internal consistency is proved by discharging the proof obligations. And finally, its satisfiability is checked by systematic testing, which executes specification and checks the outputs against corresponding inputs.

A Teleport is an integrated facility that provides its users with fast, convenient access to advanced telecommunicatoins by satellites, fiberobtics, microwave and other networks. A teleport town is an urban sub-center equipped with teleport and other telecommunication infra-facilities. This study is based on the explicit disclimination between these two related concepts. In this paper we classify various types of teleport town with respect to the specific conditions and situation in Korea. The teleport town which will be developed in Korea should be fitted into the balanced regional structure to boost up the effects of urban or regional development plan. Three models of teleport town(large scale, middle scale, small scale) are proposed on the basis of the classified types of teleport town.

All the countries in RA II (Asia Region in WMO) welcome the establishment of a Web site dedicated to agricultural meteorology, because it is believed that the best way to improve and speed up the flow of information is the use of the Internet and the establishment of a Web site. In providing recommendation for the promotion and improvement of the AgroMeteorological service in RA II, a couple of key suggestions were proposed: (a) Exchanges of data and AgroMeteorological knowledge between member countries and between RAs, (b) Exchanges of experts between member countries as a necessary way to share the knowledge, and (c) Joint research between member countries to solve common problems in AgroMeteorological affairs. In order to meet the above requirements for RA II, an AgroMeteorological information network will be the most critical and dynamic aspect in sustainable agriculture in this region. In addition, the establishment of a Core AgroMeteorological station, recommended by CAgM of WMO, will require its own information sharing systems for communication among member countries. Inevitable use of information technologies (IT) such as information networks, databases, simulation models, GIS, and RS for regional impact assessment of environmental change on AgroEcosystem will be enforced. Thus, the regional Internet-based Agrometeorological information network has been in place since 1999, though all contributions to it have been volunteered by individuals, institutes, universities, etc.

This study empahsized the nature of spatial patterns, characteristics and embeddeness of foreign business service firms in Korea utilizing questionnaire survey and interview data. Foreign business services firms are active in forming interfirm networks with clients and supply firms in Korea for widening the market share in Korea. But a low proportion of foreign firms is engaged in academies-industry linkages, government organizations, research institutes, and trade associations. Knowledge transfer and interaction also shows low level of network and the regional development of foreign firms is still in the process of developing, not quite embedded yet. Policy guidances and instituional supports are very essential to strenthen interfirm network and collective learning process of foreing firms in Korea lather than mechanical accumulation of investments. Thus, regional foreign direct investment policy should be targeted towards the incrementation of the potential of foreign firms as a knowledge-intensive industry.

A methodology to analyze and quantify regional meteorological drough based on annual precipitation data has been introduced in this paper In this study, based on posterior probability estimator and Bayesian classifier in Spatial Analysis Neural Network ISANN), point drought probabilities categorized as extreme, severe, mild, and non drought events has been defined, and a Bayesian Drought Severity Index (BPSI) has been introduced to classify the region of interest into four drought serverities. For example, the proposed methodology has been applied to analyze the regional drought of South Korea. This is a new method to classify and quantify the spatial or regional drought based on neural network pattern recognition technique and the results show that it may be apprepriate and valuable to analyze the spatial drought.
