유수사용허가업무를 담당하는 실무자들은 현행 공무원 보직체계에 따라 인사이동이 되는 경우가 많으므로 유수사용허가업무를 수행하는 담당자의 해당 분야에 대한 전문성이 결여될 수 있다. 또한, 유수사용허가 권한 자체가 수계나 하천의 등급에 따라 각 하천의 홍수통제소와 지방자치 단체에 위임되어 있어 동일한 업무이지만 업무의 일관성이 보장되기 힘든 여건이다. 따라서, 업무를 일관적으로 처리할 수 있는 시스템의 개발이 절실히 요구된다. 특히 국유인 수자원을 배분하는 유수사용허가 검토는 일관된 방법과 기준을 적용해야 하는 것이므로 컴퓨터 시스템으로 개발할 경우 간단한 조작방법을 습득하는 것만으로 업무의 일관성을 유지 할 수 있는 장점이 있으며, 여러 사용자가 동시에 접속하여 사용이 가능한 웹 프로그램을 이용한다면, 4대강 홍수통제소 및 각 지방자치단체로 분할된 업무를 하나의 시스템에서 체계적으로 수행할 수 있게 된다. 하천유수사용허가관리를 위한 시스템은 유역에 대하여 상 하류에 걸쳐 일관성 있게 적용할 수 있는 자동화된 물수지 분석을 실시할 수 있으며, 유수사용허가에 따른 허가이력 관리, 서식의 자동출력, 허가대장의 시스템과의 연계운영 등을 전산화하였다. 하천유수사용허가관리시스템은 웹기반 의사결정 시스템으로서 앞으로 각 유역에서 발생되는 신규 하천유수사용허가신청의 허가여부 검토와 허가 갱신시 허가량 조정 등에 사용할 수 있으며 수리권 및 시설물 정보의 유지 관리에 도움을 줄 것이다.

As the complexity of society increases, the demand for the forest-based recreational site is also increased. This, in turn. makes congestion an ubiquitous type of externality in forest-based recreational site. Efficient resource allocation requires this congestion effect to be accounted and considered in the decision making process. In this content, this study was conducted to suggest a process which can be used to measure the congestion and determine the optimal number of users. Willigness to pay(WTP) function obtained from Book Han San National Park users suggested that every 20.000 users increased decrease the satisfaction of users obtained from the site visit be 27.3%. For the purpose of demonstration this WTP function is applied tit determine the optimal number of users which is estimated as about 73,000 persons per day.

Based on the case of collaboration between large companies and startups, this study suggests the importance of establishing mutual cooperation and trust relationships for the success of open innovation strategy from the perspective of cooperative game theory. It also provides implications for how this can be implemented. Due to information asymmetry and differences in organizational culture and decision-making structures between large companies and startups, collaboration is likely to proceed in the form of non-cooperative games among players in general open innovation, leading to the paradox of open innovation, which lowers the degree of innovation. Accordingly, this study conducted a case study on collaboration between large company 'G' and startup 'S' based on the research question "How did we successfully promote open innovation through cooperative game-type collaboration?" The study found that successful open innovation requires (1) setting clear collaboration goals to solve the organizational problem between large companies and startups, (2) supporting human resources for qualitative growth of startups to solve reliability problems, (3) leading to strategic investment and joint promotion of new projects to solve the profit distribution problem. This study is significant in that it contributes to expanding the discussion of the success factors of open innovation to the importance of interaction and strategic judgment considering the organizational culture and decision-making structure among players, and empirically confirming the success conditions of open innovation from the perspective of cooperative game theory.

This study developed an algorithm for real-time signal control based on the detection system that can collect sectional travel time. The signal control variable is maximum queue length per cycle and this variable has a sectional meaning. When a individual vehicle pass through the detector, we can gather the vehicle ID and the detected time. Therefor we can compute the travel time of an individual vehicle between consecutive detectors. This travel time informations were bisected including the delay and not. We can compute queue withdrawing time using this bisection and the max queue length is computed using the deterministic delay model. The objective function of the real-time signal control aims equalization of queue length for all direction. The distribution of the cycle is made by queue length ratios.

This article purposes to investigate opening process of the 21st National Assembly in the middle of severe conflicts between two major-parties, and predict the changes it will bring to the operation of the National Assembly. With incumbent party's taking all leadership positions of standing committees, it broke the practice since 13th National Assembly, that is, distribution of the standing committees based on the seat-ratio. It means that our National Assembly has entered a new phase in the decision-making process. While the incumbent party, with overwhelming victory in general election, emphasizes that it should dominate legislative process to support the government, the out-party claims that they should take leverage to check over government. Two opposing trends are characteristically observed in the operation of the Korean National Assembly. First of all, due to the experience under authoritarian regimes, the National Assembly has been institutionalizing decision-making processes in the direction of enforcing cooperation between parties. On the other hand, the polarization in political parties has been stronger, making it difficult to reach consensus between parties. This article claims strongly that the 21st National Assembly need to find a balance amid such two-conflicting trends. To do so, three necessary conditions are proposed: observing decision-making procedures, securing diversity within party and National Assembly, and deliberative legislative activities.

This paper mainly deals with the appropriation of ship voyage allocation, using a heuristic regression model, in order to reduce total costs incurred in port, yard and at sea under the specific port condition. Because of different behavior of costs incurred in port, yard and at sea, an effort to minimize these costs by adjusting the number of voyages for three ship classes(50,000, 100,000, and 150,000-ton) should be made. For instance, if the port managers attempt to reduce the sea transport cost by increasing the annual allocated number of ship voyages classed 150,000-ton for economies of scale, they have no choice but to suffer a significant increase in queueing cost due to port congestion. To put it differently, there are trade-off relationships among the costs incurred in port, yard, and at sea. We utilized a computer simulation result to perform a couple of regression analyses in order to figure out the appropriate range of allocated number of voyages of each ship class using a heuristic approach. The detailed analytical results will be shown at the main paper. We also suggested a net present value(NPV) model to make a proper investment decision for an additional berth of 200,000-ton class that alleviates port congestion and reduces transport cost incurred both in port and at sea.

In 2004, in order to create core competences and major growth drivers for endogenous regional developments, the Korean government adopted the policies for establishing regional innovation systems, The main organization for the policies is the regional innovation council which is composed of diverse groups of scholars, professionals, and government officials. The regional innovation council of Kang-won Province consists of a couple of sub-divisions such as Operation Committee, Administration Office, Planning and Moderation Department, Strategic Industry Department, Culture and Tourism Industry Department, Regional Industry Department, and Regional Human Resource Development Department. The primary roles and jobs are planning, reviewing, evaluating and finalizing regional innovation policies. However, because of conflicts with local government, insufficient budget problems, organization structure problems, and decision making process problems, the regional innovation councils could not perform their original roles and functions. They could not adopt radical or non-traditional strategies. Although it's failure, a lot of people recognize the importance of regional innovation councils' roles and functions, I believe there would be another regional innovation councils coming continuously which would be take more important roles and have more power over budgeting problems. The purpose of this article is to identify the primary sources of strategies and organization structure problems of the previous regional innovation councils and to provide a couple of answers. In this paper, the author primarily analyze the problems of the Kang-won innovation council. A couple of answers to the desirable organization structures and the desirable roles of regional innovation councils will be presented for discussion.

Sewer rehabilitation is performed to improve the problem for urban drainage sewer system recently. However the data for the sewer system is not stored enough so that the sewer system is difficult to be managed systematically. In this study, a maintenance management system for urban drainage system is developed to store the data efficiently and manage the system systematically. In the developed system, a hydraulic and hydrologic analysis module is included to test the carrying capacity of a sewer pipe and estimate the amount of combined sewer overflows. The I/I and superannuation evaluation module is included in this system. The module distribute the total inflow/infiltration observed at the several sampling points in a drainage area to the individual pipes of the entire sewer system. Then the superannuation of a sewer pipe is evaluated according to the amount of I/I of the pipe. And in the developed system, the optimal rehabilitation priority module is included to determine the optimal priority and support the decision making for the sewer rehabilitation. The maintenance management system which is developed in this study is constructed by the association with the developed modules and the system is formed as graphical user interface system.

In this paper, we build a gradient Boosting model to predict government SME R&D subsidy, select features of high importance, and measure the impact of each features to the predicted subsidy using PDP and SHAP value. Unlike previous empirical researches, we focus on the effect of the R&D subsidy distribution pattern to the incentive of the firms participating subsidy competition. We used the firm data constructed by KISTEP linking government R&D subsidy record with financial statements provided by NICE, and applied a Gradient Boosting model to predict R&D subsidy. We found that firms with higher R&D performance and larger R&D investment tend to have higher R&D subsidies, but firms with higher operation profit or total asset turnover rate tend to have lower R&D subsidies. Our results suggest that current government R&D subsidy distribution pattern provides incentive to improve R&D project performance, but not business performance.

청정개발체제(CDM)란 '기후변화의 부정적 효과 완화'와 '개도국의 지속 가능한 발전 지원'이라는 기후변화협약의 양대 목표를 비용 효과적으로 이행하기 위해 교토의정서에 마련된 수단이다. CDM은 선진국인 부속서 I 국가와 이에 해당하지 않는 비(非)부속서(non-Annex) I 국가 즉 개도국이 배출감축을 위해 공동으로 노력하고 그 결과 창출된 온실가스 감축 분을 이 두 그룹 국가간에 배분되도록 한 제도다. 즉 선진국은 개도국에 자본과 기술을 투자하여 온실가스 저감사업을 벌이고 이 과정에서 발생한 온실가스 배출감축 분을 자국의 감축실적(credits)으로 인정받게 되고, 개도국은 이 과정에서 기술이전 및 재정지원의 혜택을 받을 수 있게 되어 있다. CDM은 따라서 세계 대다수의 국가가 직 간접으로 영향을 받지 않을 수 없을 것이며, 이로 인해 CDM의 구체적 실천 방안을 둘러싸고 각 국간의 이해 관계가 좀처럼 좁혀지기 어려운 상황이다. 이에 따라 지난해 부에노스 아이레스에서 개체되었던 COP-4에서는 CDM 체제를 비롯한 기후변화협약의 핵심 쟁점사항을 오는 2001년(또는 2002년)에 개체될 COP-6까지 일괄 타결키로 한 부에노스 아이레스 행동계획을 채택하는 데 그쳤다. CDM이 향후 어떤 형태로 결정되는 가에 따라 우리 나라가 받는 영향도 상당한 차이가 날 것이다. 따라서 CDM의 전개 방향을 면밀히 주시하고 이에 대한 대응책 마련이 절실히 요구되고 있다.
