Private stevedoring companies are leasing and operating the container terminals of the Busan Port. The total amount of lease fees private stevedoring companies paid in 2010 reached 161 billion wons, an approximately 66 percent of the total revenue of the Busan Port Authority(BPA). In other words, lease fees are the most important revenue source for BPA. However, the lease fee assessment system of Busan container terminals goes against the principle of equity due to different assessment methods and criteria adopted by each container terminal. Therefore, the purpose of the study is to analyze the systematic problems of the lease fee assessment system that is used at Busan container terminals, and propose a new standardized scheme with a case study on the new system. In order to standardize the assessment system, the assessment methods need to be simplified by using the Discounted Cash Flow(DCF) method. In addition, the assessment criteria such as assessment duration, discount rates, price indexes, estimated container throughputs, sales unit price per TEU, operation costs, including labor costs, need to be standardized as well. The new standardized assessment system can be applied to estimate lease fees for new terminals. However, for existing terminals to run the new system, factors such as assessment duration, discount rates, price indexes, estimated container throughputs, investment and re-investment costs, and maintenance & repair costs of the new system should be changed slightly.

Price is an important marketing issue in current competitive environment characterized by various distribution channels such as economic circumstance and the Internet. Many companies, for their best profits, use a price discrimination strategy such as price discount that reinforces consumer's purchasing behavior and they employ advertising strategy by presenting reference price with information of price discount in advertisements. Accordingly, many research verifies the advertising effects of presented reference price in advertisements, this study tries to expand the existing study area which is limited on reference price of product by examining the its effects on service area. It also aims to verify the effects of reference price advertisements by the level of service reputation. For this experiment, a factorial design with service reputation and presented method of reference pricewas used. The result of this study is that attitude toward price and use intention on presented reference price in service advertisements are higher than not presented it. In the case of high service reputation, advertising effect on presented reference price in service advertisements are greater than presented price discount rates in service advertisements. And in the case of low service reputation, advertising effects can be much greater by just presented reference price in service advertisements. Therefore, in service advertisements, strategic views on presented methods of reference price by the level of service reputation are essentially needed.

The purpose of this study is to evaluate the value of information on Bus-Route concerning on the User's Individual value. The value of information is estimated with the price of time saving by using the information. The price of unit time for each user is applied to convert the saving time to the cost. To estimate the user's expense from origin to destination the previous model is modified. Bus-travel cost is estimated with variables such as bus-travel time, bus-interval, bus-fare, and the price of walking distance. In this study, to estimate in-vehicle time the bus-travel time model is developed based on the spatial characteristics distinguished by three types of circular-road in the network of Daegu Metropolitan area. For the case study, a set of the origin and destination is selected as Dalsu-gu District Office and East Daegu Train Station respectively. There are several bus-routes which can be used as direct or transferable bus-routes selected. The study showed that when the value of time for individual users is \1,738/hr, there is no benefit to using information of transferable bus-routes. It also showed that the more discount rates of bus fare is increased, the benefit to using information of transferable bus-routes is increased, and that the lower value of time is, the benefit to using information of transferable bus-routes is increased.

This paper has statistically analyzed the determining factors that affect office building sale prices by focusing on strata property sales through the hedonic price function. In this study, 1,171 office building transaction cases were analyzed in Seoul from 2000 to 2017. To determine the influence of various factors on office building sale prices, independent variables included factors that represented macroeconomic characteristics, locational characteristics, physical characteristics, and deal characteristics. The analysis of the strata property sales, which is a major concern in this study, showed that strata property sales enjoyed a discount of about 1.56 million won per pyeong out of the entire sales. In terms of the discount rate, strata property sales were at a 12.6% discount compared to entire property sales, so it was found that strata property sales significantly influenced office building selling price. This is due to the fact that the owner of the strata property encounters more difficulties in distributing cost than the sole proprietor in terms of property rights and the exercise of management rights. The results of this study are expected to contribute in securing transparency in transactions and risk management strategies in the future.

In this paper, we deal with two pricing of bond options using the relationship between the forward rate model and the Libor rate model. First, we derive a formula for obtaining discounted bond prices using the restrictive condition of the Ritchken and Sankarasubramanian (RS), and then use the volatility function relationship of the forward rate and the Libor rate models to find the analytic solution (AS) of bond options pricing. Second, the price of the bond options is calculated by simulating several scenarios from the presented condition using Monte Carlo Simulation (MCS). Comparing the results of the implementation of the above two pricing methods, the relative error (RE) is obtained, which means the ratio of AS and MCS. From the results, we can confirm that the RE is around 3.9%, which means that the price of the bond options can be predicted very accurately using the MCS as well as AS.

For economic impact analysis on a R&D project of groundwater remediation in the metropolitan areas conducted as a fundamental research programme of KIGAM from 1998 to 2002, benefit/cost ratio(BCR), net present value(NPV), and internal rate of return(IRR) were calculated using a contingent valuation method(CVM). Measurable direct benefit parameters among the major outputs of this project consist of setup of drinking water facilities and groundwater information data valuation. In this study, economic impact of the project in NPV of year 2002, with applying a discount rate of $10.0\%$, was identified and estimated as 5.09 billion won in cost, 67.69 billion won in benefit, 62.60 billion won in NPV, 13.3 points in BCR, and $152\%$ in IRR, respectively.

This study is to give informations about management Situations and investment returns to someone who will newly cultivate schizandra or expand area of culture. This study used IRR, B/C Ratio and NPV for beneficial analysis. We surveyed fifty one among schizandra cultivation farmhouses in chief producing districts Gangwon Inje, Gyeongbuk Munkyung, Kyungnam Sancheong and Jeonnam Whasoon in Korea from May till September in 2009. So this study surveyed about inputted labors and materials, land price and etc. by working process to calculate producing and operating cost. Fruits of schizandra are sold from 5,000 won to 6,000 won per kg at locals. And IRR(Internal Rate of Returns), B/C Ratio and incomes ratio is calculated by three senarios 5,000 won, 5,500 won and 6,000 won per kg at locals. Discount rate is 3.00%. As the result of this study IRRs are -16.00%, -6.91%, 0.40% one after another and B/C Ratios are 0.81, 0.89, 0.97 one after another. And schizandra cultivation isn't profitable. When price of schizandra fruits is 6,200 won per kg, IRR is 3.00% and B/C Ratio is 1.00. Therefore, if price of schizandra fruits is over 6,200 won per kg, we judge that it is profitable. And income ratio is 23.9% on 6,200 won per kg.

정부는 그린홈 100만호 보급 사업에서 연료전지의 보급 목표를 2010년 200대 2011년 300대, 2012년 500대로 결정하였고 이에 따라 2012년까지 누적 보급대수가 1000대에 달할 전망이다. 본 연구에서는 현재 상업화 되어있는 국내업체의 1kW급 가정용 연료전지 시스템을 2009년에 도입되는 것으로 가정하여 경제성평가를 수행하였다. 분석의 편의상 2009년 서울 지역 난방면적 $100m^2$을 기준으로 전제하였고, 대표가정의 전기와 열수요는 CES 소형 열병합 사업 타당성 분석 프로그램(GS파워, 2006)을 활용하여 구했다. 비용의 경우 기존 보일러의 설비가격은 60만원이며 연료전지시스템의 설비가격은 1200만원이다. 다만 연료전지의 고가 소모품인 스택은 2007년 발간된 한국에너지 기술연구원의 신재생에너지 경제성평가 보고서를 인용하여 스택의 수명은 5년, 교체비용은 1000만 원이나 5년마다 30%의 비용 하락을 전제하였다. 또한, 연료전지시스템의 수명을 20년으로 가정하였으며 할인율은 5.5%를 가정하였다. 한편, 가정용 연료전지의 최적 운전방안을 찾기 위해서 기존 설비를 이용한 비용과 전기추종운전, 열추종운전의 시뮬레이션을 수행한 뒤 세가지 결과를 시간대별로 비교함으로써 최적의 시간대별 운전방식을 선택하는 복합추종운전의 비용을 분석하였다. 시뮬레이션결과, 기존 설비 이용 시 에너지 비용은 1,934,864원으로 분석된 반면 연료전지를 이용한 전기추종은 1,123,691원, 열추종은 1,180,425원, 복합추종은 1,121,174원으로 계산되었다. 한편 편익면에서는 복합추종운전시 813,690원의 편익이 발생하는 것으로 분석되었으며 B/C ratio의 결과는 0.405로 현재로서는 연료전지 시스템이 경제성이 없는 것으로 분석되었다. 따라서 정부는 연료전지의 보급목표와 민간 주도의 자생적인 시장형성을 촉진하기 위해서 단순 설치 보조금 이외에 연료전지시스템과 스택의 비용을 획기적으로 저감 시킬 수 있는 기술개발을 촉진하는 정책 병행이 필요해 보인다.

In this paper, the cost-benefit analysis is used to compare policy alternatives on whether the Korea National Museum of Contemporary Art should be incorporated or not. Alternative 1 (Current State) is to remain as it is. Alternative 2 (Incorporation State) is to change its legal status from government agency into incorporation. To make the process of incorporating, some assumptions are introduced: (1) no labor workforce reductions, (2) wage increase, (3) keeping publicness. These assumptions reduce the resistance from worker and provides them incentives to accept the incorporating process. Those assumptions also reflect the direction of policy of the government. After estimating the net present values of each alternative, it turns out that the NPV of Alternative 2 (Incorporating State) is larger than that of Alternative 1 (Current State). This result holds after doing sensitivity test using different discount rates.
