수리권은 물을 소유할 수 있는 권리가 아닌 지속적이고 배타적으로 물을 사용할 수 있는 권리를 의미한다. 국내 수리권은 공유하천용수권, 관행수리권, 허가수리권, 댐사용권 및 농어촌용수 수리권으로 구분되어 있다. 미국의 경우 연안주의 수리권 (Riparian Rights), 유용한 사용의 원칙 (Beneficial Use Doctorin)에 근거한 우선전용 수리권 (Prior Appropriation Rights)으로 구분되어 있으며 물 분쟁이 발생할 경우 동등배분원칙에 따라 해결방안을 제시하고 있다. 일본 수리권의 경우 댐 건설할 경우 건설 주체 및 비용 분담이 명확하게 규정되어 있어 별도의 수리권 규정 절차가 없으며 농업용수에 대한 관행수리권 또는 기득수리권이 존재할뿐 그 외의 생활용수 등에 대한 수리권은 존재하지 않는다. 이렇듯 본 연구에서 검토된 국내외 수리권 법률 및 해결 방안에 대한 비교 및 검토 결과는 향후 국내의 수리권 법률 규정에 기초 자료로 활용 될 수 있을 것이다.

This paper proposes a method and its implementation for searching, converting, and delivering composite events and actions in the U-City Integrated Management Platform to process them efficiently through allocation and collaboration between the platform and u-services. The purpose of this method is to, when a composite event occurs, execute prompt and correct measures to reduce the damage caused by the event and prevent its spread. The proposed method also helps to simplify the complexity of corresponding business processes by modifying composite events and actions that are frequently added, delete, and revised, and delivering them to u-service systems.

In this paper, the selection of transport route for import-export container cargo based on the sacrifice model and CO₂ emission was investigated. At first, the transportation of import-export container cargo, the transport share of each transport route, the CO₂ gas emission, the sacrifice model and the time value of import-export container cargo were investigated. And next, the selection of transport route based on the sacrifice model was investigated for the transport of import-export container cargo from Seoul to Pusan Port. Finally, the transport route was also selected by using the sacrifice model including the effect of CO₂ emission. The research results show that the transport route selection results of import-export container cargo based on the sacrifice model represents the present status of the transportation of import-export container cargo very well. And also the research results show that the reduction of transport time was very effective to increase the share of coastal transportation.

Since the introduction of New Towns in Seoul MSA, land price has steadilly been risen due to the financial burden of constructing metropolitan transportation facilities. Despite metropolitan transportation facilities are utilized by New Towns as well as its surrounding area, the current situation is that most of the burdens, which is supposed to be shared with local governments, fall to developers. This study, with the case of Dongtan New Town, is to deduce rational structure of cost-sharing by the analysis of travel demands of metropolitan transportation facilities. Also, for the financing of the cost, the application methods of TIF(Tax Incremental Financing) have been suggested. The results showed that the proportion of travel which origins from New Town was 35.1%, which results in 800 billion won for the share of local government. For financing this amount of the cost, at least 20 years of financial period and the rate of 2% increase of real estate are needed in operating the TIF.

Since the OPRC-HNS Protocol entered into forced in the June of 2007, the potential effects on industrial circles are encouraged to be analyzed according to the obligatory regulations listed in the Protocols. This study was conducted on the quantitative analysis of the possible effect on the industrial circles if Korea accedes to OPRC-HNS Protocol. In spite of any burdens caused by keeping "accident emergency program memorandum" and performing "education and any training program for the crews", potential decrease of insurance fee is in possibility provided it follows. In addition, the oil refinery and petrochemical industries may also have burdens for potential costs for acquiring any materials including equipments and fees for education and training related to HNS. However, minimizing any costs by swift response against accidents would be big advantage that comes with paying of small amounts of expense by international convention related to HNS.

This study extended Park et al.(2007c), which analyzed the efficiency of a hierarchical transit network, showed the result of a real data, and analyzed its applicability. Operating cost was estimated using a model which was established in this study, and minimum transit demand was derived from the operating cost. The minimum transit demand value is just a sample calculation, thus it varies by many inside and outside factors of the model. Looking at the inside of the model, operating cost and travel speed are major factors, and the possibility of introducing urban subway becomes high when the operating cost of the transit system is low and its travel speed is high. As far as the outside factors are concerned, according to the analysis on the network structure, transit demand, and transit mode share, the minimum transit demand value which was derived in this study will be the maximum value among the possible values. In the feasibility study, the benefit is likely to be overestimated and the cost is likely to be underestimated than those of this study. It could be concluded that the methodology of a feasibility study is appropriate in the field standard. This study analyzed the efficiency of introduction of urban subway using analytical approach, thus has many shortcomings and limitations. However the practical approach, like feasibility study, has some limitations as well. This study could be a basis on establishing an analysis framework that is more accurate and reasonable by comparing analytical approach and practical approach.

The modal spilt of highway has been increased and the one of railway has been decreased from 17.2%(1990) to 6.3%(2006). In this context, it is meaningful to examine the competitiveness of the railroad of Korea. The objective of this study is to analyze the competitiveness of railroad with the highway so that countermeasures improving the competitiveness of railroad could be suggested. For this, firs of all, indicators representing the competitiveness of the railroad transport are determined. The main influencing factors for mode choice include transport time, transport cost and level of service. Three types of commodity, container, cement and steel are the target for the analysis. It was found that the overall competitiveness of railroad transport is weaker compared with highway even for the main freight origin-destination pairs. It means that the freight transport system is focused on road rather than railroad. Therefore, we need to remeasure the competitiveness of railroad transport related to methods for freight railroad competitiveness improvement.

The existing route re-establishment methods which intend to extend the lifetime of the network attempt to find new routes in order not to overly consume energy of certain nodes. These methods outperform other routing algorithms in the network lifetime extension aspect because they try to consume energy evenly for the entire network. However, these algorithms involve heavy signaling overheads because they find new routes based on the flooding method and route re-acquisition occurs often. Because of the overhead they often can not achieve the level of performance they intend to. In this paper, we propose a new route re-acquisition algorithm ARROW which takes into account the cost involved in the packet transmission and the route re-acquisition. Since the proposed algorithm considers future route re-acquisition costs when it first finds the route, it spends less energy to transmit given amount of data while evenly consuming the energy as much as possible. Using 2-dimensional Markov Chain model, we compare the performance of the proposed algorithm and that of other algorithms. Analysis results show that the proposed algorithm outperforms the existing route re-acquisition methods in the signaling overhead and network lifetime aspects.

The Purpose of this Paper is the development of the day-to-day dynamic combined model on the evaluation of traveller's traffic information for multi-mode and multi-class environments. Information is assumed to be provided for multi-mode such as bus and automobile. and multi-class such as a driver with and without route guidance equipment when they depart for their trips. The information provision strategies have been developed in the base of user equilibrium, system optimum and in between them. The Sioux Falls network is used for the evaluation of the model and information provision strategies. In the numerical analysis, a Braess' paradox for the information provision, which is the increase of travel time even though the number of information usage level and user are increased, has been occurred so that these kinds of information strategies should be implemented with special care.

Currently financial support for vocational skills development training is provided based on the NCS standard unit price set according to the NCS occupational classification. Such a standard unit price system has the advantage of reducing administrative burdens required in managing the training levy-grant system. In this paper, it is pointed out that current unit price system may distort the social integration function of vocational training policy as it is based on the tuition fees of training course. As a basis for finding a more appropriate financial support system, we analyzed what factors are influencing the training course fees set by training institutions. As a result, it was confirmed that the monopolistic nature of the training courses or the high level of willingness of pay of training participants influenced the training course fees. Therefore, the necessity of removing the influence of such factors from unit price system was suggested so as that the training policy contributes to the social integration. Furthermore, it is required to establish new support criteria centered on the government's policy judgment if the training costs of all training courses cannot be exactly estimated.
