This paper aims to consider an overall benefit-duration optimization (OBDO) problem for the sake of maximizing owner's economic benefits, whilst considering influences of schedule compression incurred opportunity income on the profitability of a large-scale construction project. Unlike previous schedule optimization models and techniques that have focused on project duration or cost minimization, with greater weight on contractors' interests, OBDO facilitates owner's economic benefits through overall benefit-duration optimization. In this paper, the objective function of OBDO model is formulated. An example is illustrated to prove the feasibility and practicability of the overall benefit-duration optimization problem. The significance of employing OBDO model and future research work are also described.

Rice cultivation is not only the main resource of farm income and staple food but also the root of cultural life of Korean people. Korean government has carried out irrigation water development with heavy investment to cope with water shortage in rice fanning as a link of the five years economic development plans. In spite of the continuous accomplishment of irrigation water development, the marginal benefits-costs of irrigation water has not been studied. Owing to the government full support for the operation and maintenance of irrigation facilities, price of irrigation water as a membership fee could not be formed as the municipal and industrial water prices. Accordingly this study is aimed at identifying firstly the marginal benefits-cost of irrigation water, secondly deriving the macro-econometrics models as supply and demand functions of irrigation water and thirdly examining the marginal benefits-cost ratio. The trends of supply and demand prices of irrigation water were estimated annually. Considering the marginal benefits-cost ratio as 1.3, it was identified that additional irrigation water development projects still have an economic feasibility under the present economic situation in Korea.

Water is an indispensable input to human's existence and industrial production. In these days, people are getting more concerned about their health and the interest in the safety of drinking water has increased. In this situation, this paper attempts to measure the economic benefits of the tap water quality improvement. The study area was restricted to Busan, the second largest city in Korea, where local government is planning to implement a tap water quality improvement program. We apply a one-and-one-half bounded dichotomous choice contingent valuation (CV) method to obtain at least a preliminary evaluation of the benefits. CV is developed for valuing goods or services that cannot be valued either directly or indirectly from market observations and has been applied to several environmental goods. The CV survey was rigorously designed to comply with the guidelines for best-practiced CV studies. We surveyed a randomly selected sample of 400 households in Busan and asked respondents questions in person-to-person interviews about how they would be willing to pay for the water quality improvement. Respondents overall accepted the contingent market and were willing to contribute a significant amount (US$1.66), on average, per household per month. We can also calculate the aggregate value of the program which improves the water quality in Busan. This study is expected to provide policy-makers with useful information for evaluating and planning environmental policies relating specifically to water.

The purpose of this study is to analyze the adoption of Kakao Bank in terms of benefits (functional, social, experiential, economic benefits) and differentiated services (customization and service diversity) considering service types. Benefits are personal value consumers attach to the product or service attributes and, therefore, more important than attributes of service itself when using Kakao Bank in the internet based environment. Data was collected using an online and offline survey of 131 Kakao Bank users and analyzed the data using structural equation model (SEM). The results of empirical analysis using SmartPLS show that functional benefit, experiential benefit, and customization are significantly related to the user's satisfaction, but economic benefits, social benefit, and service variety are not. Customer's satisfaction are also showed significantly to be related to the all types of Kakao Bank usage(balance check, transfer, and other services). This study has the significance in that it examines the user's satisfaction and usage of Kakao Bank in terms of benefits and differentiated services while other studies analyzed banking services focusing on the attributes of banking channel itself.

본 연구는 북한 산림복원을 생태계 서비스의 관점에서 비용-편익 기반 경제적 가치로 확인하였고, 산림복원 형태에 따른 경제성을 비교하였다. 특히 산림복원에 따른 편익을 탄소저장, 수자원공급, 토양유실방지, 재해저감 등 생태계 서비스로 분류하고 경제적 가치로 환산하여 종합적 편익을 산출하였다. 산림복원 시나리오에서는 최근의 북한 조림실적과 산림정책을 고려하여 '단독조림 시나리오'와 '산림협력 시나리오'를 구성하여 동일한 복원기간이나 조림의 양적 물량 차이를 시나리오로 도출하였다. 단독조림 시나리오에서는 향후 20년 동안 3조 8,294억원의 비용으로 80만 ha의 산림을 복원하여 6조 8,684억원의 편익이 발생할 것으로 산출되었다. 순현재가치로 경제성을 평가하였을 때, 3조 390억원으로, BCR은 1 이상이었다. 산림협력 시나리오에서는 10조 531억원의 비용으로 220만 ha의 산림을 복원하여 18조 8,909억원의 편익이 발생할 것으로 산출되었다. 마찬가지로 순현재가치로 경제성을 평가하였을 때, 8조 3,599억원이며, BCR은 1 이상이었다. 두 시나리오에서 모두 BCR은 1 이상으로 경제성을 갖는 것으로 도출되었으나, 예상되는 편익의 양에는 큰 차이가 있었다. 다만, 조림면적에 따른 단순화된 비용-편익 분석이므로, 경제성(BCR)이 유사하게 나타나는 한계가 있으며, 조림속도나 생물리적 차이를 고려하지 않았다. 결론적으로 산림복원은 비용보다 편익이 높은 사업이 될 수 있으며, 산림협력을 통해 그 가치를 증진시킬 수 있다. 장기적으로 이러한 경제성이 근거가 되어 기업과 국제·민간기구 등의 협력을 통해 다양한 형태의 산림협력이 추진되길 기대한다.

Purpose: This study purposed to analyze the economic feasibility of introducing a third party logistics system as a strategic alternative to hospital management. Methods: Economic analysis was performed by measuring changes in costs and benefits before and after implement the third party logistics system and estimating the size of net benefits for the next five years for the target hospital. A questionnaire survey and in-depth interview with stake-holders were conducted to find out the satisfaction and effectiveness of the system. Findings: According to results, the cost-benefit ratio for the implementation of the system was 1.18. For the next five years, the cost-benefit ratio was 1.48, the net present value was about 1.7 billion won, and the internal rate of return was 64%. The satisfaction of internal stake-holders was relatively high, in terms of improving the concentration of unique tasks and increasing the efficiency of inventory management. Practical Implications: It was found that the increase in benefits had a greater effect on the change in the cost-benefit ratio than the increase in costs resulting from the expansion of logistics, and the increase in the present value of net benefits gradually decreased as the cost increased. In addition, overall job satisfaction and satisfaction with outsourcing companies were relatively low, which means that stabilization of the new system is important. Further study is needed for more accurate economic analysis.
