Along with the urbanization, the risk of urban flooding due to climate change is increasing. Flood regulation, one of the ecosystem services, is implemented in the different level of function of flood risk mitigation by the type of ecosystem such as forests, arable land, wetlands etc. Land use changes due to development pressures have become an important factor in increasing the vulnerability by flash flood. This study has conducted evaluating the urban flood regulation service using InVEST UFRM(Urban Flood Risk Model). As a result of the simulation, the potential water retention by ecosystem type in the event of a flash flood according to RCP 4.5(10 year frequency) scenario was 1,569,611 tons in urbanized/dried areas, 907,706 tons in agricultural areas, 1,496,105 tons in forested areas, 831,705 tons in grasslands, 1,021,742 tons in wetlands, and 206,709 tons in bare areas, the water bodies was estimated to be 38,087 tons. In the case of more severe 100-year rainfall, 1,808,376 tons in urbanized/dried areas, 1,172,505 tons in agricultural areas, 2,076,019 tons in forests, 1,021,742 tons in grasslands, 47,603 tons in wetlands, 238,363 tons in bare lands, and 52,985 tons in water bodies. The potential economic damage from flood runoff(100 years frequency) is 122,512,524 thousand won in residential areas, 512,382,410 thousand won in commercial areas, 50,414,646 thousand won in industrial areas, 2,927,508 thousand won in Infrastructure(road), 8,907 thousand won in agriculture, Total of assuming a runoff of 50 mm(100 year frequency) was estimated at 688,245,997 thousand won. In a conclusion. these results provided an overview of ecosystem functions and services in terms of flood control, and indirectly demonstrated the possibility of using the model as a tool for policy decision-making. Nevertheless, in future research, related issues such as application of models according to various spatial scales, verification of difference in result values due to differences in spatial resolution, improvement of CN(Curved Number) suitable for the research site conditions based on actual data, and development of flood damage factors suitable for domestic condition for the calculation of economic loss.

This study analyzes the contract terms to explore whether the content has any improper and/or unfair clause, reviews the consumer-related laws, and examines the activities of the regulatory systems in the telecommunication service markets. The major resets of the stud\ulcorner are: first, the level of regulation to contract terms is inconsistent across the services areas and needs to be coordinated; second, the standard contract terms need to be developed; third, the policy implications with respect to regulatory policy making and public education are developed; and lastly establishment of consumer advisory board to advise the commission on consumer issues and the consumer information and education center is suggested.

The current software company report system in Korea has many problems in its efficiency and effectiveness. In this paper, we investigated the system by surveying the contracting officials and contractors in software development. By analyzing current status and some problems with the survey results, we derived an feasible improvement scheme for the software company report system. We suggested efficient procedures and reporting items for the registration process, some benefits for contractors, and the short-term direction for its implementation.

이동전화시장에 대한 규제여부를 논의할 때 가장 중요한 요인으로 이동전화시장의 경쟁상황을 들고 있다. 대부분의 이동망 비규제를 주장하는 측의 논리는 이동전화시장은 복수사업자체제로 치열한 경쟁이 전개되고 있기 때문에 고정망에서와 같은 강력한 규제가 대칭적으로 적용되어서는 안된다는 점을 강조하고 있다. 본 고에서는 이러한 주장의 타당성을 검토하고 합리적인 이동망 시장 규제대안을 모색해보기 위해서 이동전화 시장구조를 살펴보고 세분화된 이동전화 시장 내에서의 경쟁상황을 검토하였다. 아울러 본 고에서는 이러한 분석을 바탕으로 세분화된 이동전화 시장상황에 적합한 정책 및 규제 대안을 제안하였다.

캐나다의 통신시장 자유화 및 경쟁도입은 비교적 늦게 시작되었지만, 지금은 세계 어느 나라보다 경쟁적 환경이 각 분야에서 전개되고 있다. 이는 정부의 정책과 산업계의 활동이 경쟁 강화와 시장확대에 초점을 맞추고 있기 때문이다. 따라서, 캐나다 통신서비스 산업을 이해하기 위해서는 그 근간이 되는 규제측면에서의 이해가 전제되어야 하며, 본 고는 이런 맥락에서 규제기관의 주요 경쟁도입 결정과 그 후속조치로서의 경쟁환경 조성 제반조치 등을 중심으로 최근 10년간의 캐나다 통신서비스 산업 전반을 분석하였다.

Urban green spaces supply ecosystem services (ESs), which are consumed by city residents and generate demand, to improve air quality. It is important to determine supply and demand for ESs and reduce the gap for efficient management. This study proposed a method to use the concept of supply and demand for ESs in the decision-making process for urban planning or management. PM₁₀ concentrations were converted to weight for demand assessment on PM₁₀ reduction, and PM₁₀ absorption capacity of all green spaces including the forests, and that of urban green spaces excluding forests, was calculated for each supply assessment. The differences in the calculated supply and demand were analyzed to derive the mismatched regions in Suwon. As a result, regions with big forested areas showed sufficient supply, indicating that the degree of mismatch among administrative neighborhoods (dong) varied greatly depending on whether they had a forest. An analysis of only urban green spaces showed that all neighborhoods lacked supply. Forests with high PM₁₀ absorption capacity had a great effect, but urban green spaces can be considered a key element in reducing PM₁₀ in daily life. Considering the mismatch of supply and demand, spatial distribution, and population distribution, it is possible to prioritize the supply of urban green spaces to reduce PM₁₀ and, furthermore, support decision making for priority zones subject to forest conservation and designation and cancellation of green spaces, which gives significance to this study.

본 연구의 목적은 해외유료방송의 시장집중과 시장성과 간의 실증적인 관계분석을 통해 국내 미디어산업의 바람직한 규제 및 정책 방향을 고찰해 보는 것이다. 세계적으로 방송통신이 융합되어 규제가 완화되고 있음에도 불구하고, 국내의 경우에는 미디어 시장이 특정사업자에 집중될 경우 시장 비효율이 발생하고 다양성이 훼손된다는 전제 하에, 여전히 시장집중현상을 집중적으로 규제하고 있다. 본 연구에서는 전 세계 17개 유료방송시장을 대상으로 1위 사업자의 시장점유 정도가 시장가격과 서비스 보급에 영향을 미치는지 분석하였다. 조사결과 시장집중 현상이 초래되어도 가격이 상향되거나 서비스 보급이 지연되는 않는 것으로 분석되었다. 본 연구결과, 시장성과에 영향을 주는 요인들이 다각화되었기 때문에 단순히 시장집중만을 규제하면 기술혁신 침체와 같은 부작용도 발생하는 것을 포함하여 다양한 시사점들이 도출되었다.

Recently, many countries have placed great attention on energy security and climate changes. Governments are promoting the construction of renewable energy projects with regulatory support in Korea. Despite an increasing penetration of renewable resources, however, the photovoltaic and wind power are underutilized due to the endemic problems such as difficulties of output control and intermittent output. The Energy Storage System (ESS) is proposed as a good solution for solving the problems and has been studied in both the private business and the government. However, because of inefficient aspects, the research has been carried out for improving high costs and a small capacity. In addition, the ESS is currently installed for using only one purpose which is frequency regulation or transmission congestion relief such that has an economic limitation. Therefore, methods which are becoming economically justifiable to increase the penetration of the ESS is required. Thus, this paper presents in terms of operation efficiency to improve economic feasibility of the ESS currently used. mainly, there are two aspects for the operation efficiency. Firstly, it is intended to improve the utilization rate through a process that can utilize the ESS for various purposes. It is necessary to be able to use for other purposes by classifying and clustering for increasing the efficiency of availability. The clustering method is proposed to conduct the grouping the ESS. Especially, it is proposed to utilize ESS for frequency regulation service which is the one of ancillary services in the power system. Through case studies, it is confirmed to secure the necessary resources by clustering small size ESS.
