Korea needs to develop a rational system to separate stormwater utility fee from current sewerage fee. In this study, the scenario for calculating stormwater utility fee of Bupyeong-gu was suggested and the results were considered. For this purpose, the application of stormwater utility fee overseas and current domestic system were analyzed. A three step calculating scenario considering suitable domestic situation and impervious surface area was suggested. Water, sewerage usage, and hydrant data were collected. The total amount of water and sewerage fees for land use were calculated. The sewerage fee of Bupyeong-gu for the year 2014 was 21,685,446,578 won. Assuming that 40% of this amount was the cost associated to stormwater, the result showed that the fees for residential area in third step decreased by 0.77% compared to that of the first step. For commercial area, the stormwater utility fee decreased by 36.87%. For industrial area, although the consumption of water was similar to that of commercial area, the stormwater utility fee increased by 8.35%. For green area, the fee increased by 37.46%. This study demonstrated that the calculation of actual stormwater utility fee using impervious surface map and impervious Surface Ratio Estimation Methodology developed in previous studies is feasible.

This paper investigated policies that drive the sustainable management of Ivorian forest which disappear at an annual rate of 250000 hectares. Based on an inter-temporal model for optimum allocation of forest land to three competing uses, the article found that sustainability depends on the incentive structure, of which forest taxes and fees are a key, though obviously not the sole, component. The study proposed to increase the area fee level by accounting for environmental externalities generated by forest harvesters and farmers. The paper showed that the area fee is a decreasing function of the forest natural rate of regeneration and the reconversion rate of agricultural surfaces. Finally, at the given forest natural rate of regeneration and the reconversion rate of agricultural surfaces, the model argued that the area fee need to be progressive (arithmetic progression) in the context of ecological equilibrium break while it should remain constant in normal situation.

Management of stormwater runoff is considered a nationwide challenge. To deal with this challenge, many researches have been conducted to study initial stage of stormwater fee imposition. The objective of this study was to recommend a framework for stormwater fee imposition not only for funding the stormwater management programs but also for encouraging people to decrease impervious area. This study focused on, regulations, financial resources and international cases related to stormwater runoff management. Polluter pays principle, which is generally recognized environmental policy principle is regarded the basis of stormwater fee imposition. Three components suggested for the stormwater rate structure are 1) stormwater utility revenue requirement, 2) billable equivalent stormwater unit, 3) system unit cost. The key point of stormwater rate structure is the "Equivalent Residential Unit(ERU)". The concept of an ERU is one residential area with a runoff coefficient. The runoff coefficient is that portion of rainfall that becomes runoff rather than infiltrating into the ground. In addition to this, this study took into account the observed data simulation for the separation of stormwater treatment expenditure from the comprehensive wastewater treatment cost.

As sewer flooding frequents due to localized and concentrated stormwater and increased non-permeable surface area after urbanization, building cities with sound water recycle and accordingly efficient management of rainwater is demanded. To do this, the existing sewage (including rainwater) fee imposition system should be philosophically evaluated. This study presents problematic issues of the existing domestic sewage fee imposition system considering the principle of sharing costs on the service of sewage and rainwater collection and treatment. Four methods to improve the existing sewage fee imposition system are suggested: 1) imposing stormwater fee according to Polluter Pays Principle, 2) clarification of the share of public sector, 3) reducing or exempting the sewerage fee for inhabitants reducing urban runoff by constructing their own rainwater management facilities, 4) imposing charge for discharging rainwater to sewers due to new development action. Short, mid, or long term planning for rainwater management is recommended considering the situation of each municipality.

This study is aimed to get clear model for CM fee level in public construction project. For the practical use and main target, CM for fee contract only is assessed and analysed. Cost estimate by percentage of total contract sum and method based on the historical construction data have significant deficiency. An regression model and probabilistic model are suggested with 9 independent variables. In the case of limited work scope, an element based floor area model is suggested and concluded with fish-bone scheme.

A new colloidal silver (Ag) system is present in which a fine colloidal Ag is in situ deposited onto functionalized porous poly (ethylene glycol dimethacrylate) (poly (EGDMA)) microspheres. The effectiveness of Ag deposition was investigated considering the surface characteristics of poly (EGDMA) microspheres. The result reported in this study illustrates that the control of surface area and surface functionality (in this study, a hydroxyl group) of poly (EGDMA) microspheres is an important factor that determines practically the degree of deposition of colloidal Ag. The x-ray analysis showed that Ag nanoparticles were dispersed evenly inner and outer surfaces and had a face center cubic (fee) phase. In the preservative efficacy test, the Ag-containing poly (EGDMA) microspheres had a powerful anti-bacterial activity, showing a high potential for a new preservative in cosmetic industry.

본 연구는 헤도닉가격기법(hedonic price method)을 활용한 경기도 남양주시의 2012년도 지가 분석을 통해 수질보호구역으로 인한 경제적 손실을 추정하고, 한강 하류지역에 수혜자부담원칙에 의해 부과되는 물이용부담금 제도에 대한 평가 의견을 제시한다. 분석결과 Double-log 모델이 수질보호구역으로 인한 영향을 추정하는데 보다 적합한 모델인 것으로 나타났으며, 본 연구에서 사용된 Double-log 모델에 따르면 남양주시에 대한 적정 총 보상액은 약 8.6조원으로 추정되었다. (95% 신뢰구간: 약 4.4조-12.4조원) 또한, 영구연금지급방식에 따른 남양주시에 대한 연간 보상액은 약 0.9 조원으로 추정되었으며 (95% 신뢰구간: 약 0.4조원-1.2조원), 이는 추정된 적정 연간 보상금이 2012년에 징수된 한강수계에 대한 물이용부담금 총액 (약 0.5 조원) 보다 높다는 것을 보여준다. 특히, 팔당지역의 국유지를 제외한 수질 보호구역의 면적이 (약 $2,572km^2$) 남양주시의 수질보호구역 면적의 (약 $140km^2$) 18 배가 넘는 점을 고려할 때, 한강상류지역의 재산권 침해에 대한 적절한 보상을 위해 수혜자부담원칙에 따라 하류지역에 부과되는 물이용부담금의 인상이 필요할 것으로 판단된다.

As a rise in national income has resulted in the growth in tourism demand, many studies on developing and managing tourism resources were publicized. In this context, this study was conducted to analyze the demand and willingness to pay(WTP) using contingent valuation method for agricultural experience of Daegu Urban Agriculture Park and to suggest a proper participation fee. The survey targeting Daegu citizens was performed, and we obtained 346 valid samples. We carried out the logistic analysis and figured out that sex, age, education and alienation area for urban agriculture affected to probability of agricultural experience participation. As the result of estimating willingness to pay(WTP), the measured range with this samples was from 6,052 to 16,436won. Finally, we also attained 25,000won as the proper participation fee which enables maximum revenue by conducting the scenario analysis. These findings are important in setting up the construction plan and pricing the appropriate participation fee for Daegu Urban Agriculture Park.

지난 2008년도에 기존의 기반시설부담금제가 국토계획법 상 기반시설부담구역제도로 개정되면서 2009년도 이후 전국적으로 다수 지자체들이 본 제도를 도입, 시행하고 있으며 이러한 새 제도를 통해 난개발 방지를 위한 선계획의 마련과 기반시설 설치비용 확보를 위한 유용한 제도적 기반을 가지게 되었다. 이러한 맥락에서 본 연구는 기반 시설설치계획과 기반시설부담비용 산정과정에 앞서 필요한 기반시설부담구역 지정에 대해 시행령에서 명시한 인구증가율 기준을 근거로 인구격자의 수직수평방향 사출형 셀 집단화 방법을 통해 구역지정 대안을 검토해 보고 이를 실제 기반시설부담구역 지정이 필요한 것으로 판단되는 화성시 수영리 개발제한구역 일원 대상지에 적용해 봄으로써 상기 방법론의 기술적 적용가능성을 확인함과 동시에 실무적 차원의 구역결정 제언을 시도해 보았다는 데 연구의 의의가 있다.
