Korea's recent attempt to separate prescription and dispensation of pharmaceuticals suffers serious, negative side effects. The interned-based prescription delivery system is being considered a supportive tool to alleviate such side effects. This paper conducts an economic evaluation of the system. We consider all possible types of pecuniary costs and benefits, from societal perspective, to conclude that nationwide adoption of the system would raise net social benefits by 5,892 billion won for the coming five years. Specifically, the net benefits would be distributed among consumers (5,667 billion won), pharmacies (216 billion won) and medical institutions (8 billion won). Net social benefits would be far mere enhanced by deregulation policies, such as removal of restrictions on electronic type prescription and home-delivery of dispensed drugs.

The volume of B2C products rapidly increases according to the activation of the electronic commerce. Small and medium electronic commerce companies request the establishment of Parcel Warehouse &Distribution Center(PWDC) that is invested by the post office. This paper presents an economic evaluation method for PWDC from the perspectives fo PWDC and the post office. Two types of warehouses are considered as alternatives for PWDC. One is the conventional warehouse, and the other is the automamic warehouse that is characterized by AS/RS and automatic dispenser system. A benefit/cost analysis method is used to evaluate PWDC since it has the property of public enterprise. A PWDC which will be located in Seoul and adjacent to a concentrated post office is selected as a case study to illustrate the procedure of economic analysis.

In this paper, the method on calculating benefits of combined heat and power is introduced for standard evaluation in electrical power system. This paper calculates benefits about new national viewpoint and viewpoint of independent power producers and assesses benefits of combined heat and power in Korea and In Seoul national capital area. Benefit costs are composed of avoid cost of centralized generation, line upgrading adjustment, loss adjustment and electrical power trade cost per year in earlier study, in addition trade cost of CO2, construction cost of combined heat and power for accurate calculation. Benefit of combined heat and power is calculated by simulation results of real electrical power system.

As cost invested in developing the specified technology is increasing, investors are paying more attention to cost to benefit analysis (CBA). One of the basic elements of CBA for new technological development is the diffusion pattern of demand of such technology. Many studies of technology evaluation have adopted a single generation model to simulate the diffusion pattern of demand. This approach, however, considers the diffusion of the new technology itself, not taking into account a newer generation that can replace the one just invented. In this paper, we show how a multi-generation technology diffusion model can be applied for more accurate CBA for information technology. Monte Carlo simulation is performed to find influential factors on the CBA of a Cybernetic Building System.

The aim of this paper is to evaluate users benefit values of theme park using Travel Cost Method with special reference to Woobang Tower Land in Taegu for the estimation of economic values. This research is mainly based on questionnaire survey of 100 users of the theme park. Socio-economic factors such as income, year of education, annual income, age and money(travel cost) are analysed from 5 residential areas of the respondents. Multiple regression analysis was used for the evaluation of annual number of park visitings based on the analysis. The regression model shows NV = $\alpha$+$\beta_1$TC+$\beta_2$INC+$\beta_3$EDU+$\beta_4$AGE (NV : Annual Number of Visitings, TC : Travel Cost, INC : Annual Income, EDU : Years of Education, AGE : Age). Regarding to visitors demand curve based on the equation showed that annual economic values of Woobang Tower Land was estimated as 50billion Korean Won.

The purpose of this study was to investigate the online review writing motives of online shopping on repurchase intention and recommendation intention about fashion merchandise. The questionnaire was administered to 279 people who had experience in online shopping. The data were analyzed by utilizing factor analysis, multiple regression analysis and t-test. The results of this study were as follow. First, the online review writing motives were divided into three categories such as benefit pursuit/hedonic shopping value, information transmission and evaluation. Second, the consumer who has experience of writing review prefers to repurchase other products in that online shopping mall and to recommend those products more than the consumer who doesn't have that experience. Third, the benefit pursuit/hedonic and information transmission had an effect on repurchasing intention and recommendation intention.

Nowadays, it is planning to establish a coastal VTS in Korean southern coastal waters in order to enhance the safety of vessel traffic and to protect the marine environment. But, it surely needs over ten billions Won to establish, operate and maintain the above mentioned coastal VTS. Therefore, this paper proposes the VTS cost-benefit analysis model to confirm the reasonability and decide the priority of the project. This model has three distinct processes. Fist, it is the identification in qualitative terms of the effects of a given proposal. Second, it quantify the specified effects in physical terms. Third, it is the evaluation of the total effects of project. The proposed model in this Paper will contribute to the confirmation and the priority of the project in future.

Telemedicine can increase accessibility to advance medical technology at the university hospital for community residents living in a remote area. This paper focused on the economic evaluation of telemedicine to identify important factors influencing costs and benefits and to understand how these factors can be changed to improve economic performance of the telemedicine. When the telemedicine project currently operating in Korea was evaluated based on the traditional cost-benefit analysis, the results showed a heavy net loss wiht a B/C ration of 0.56. As several values were added to the analysis based on the Information Economics approach, B/C ratios steadly increased. When the saving of medical expenses from the early detection of diseases was taken into a consideration, the ration exceeded the break-even point. >From the sensitivity analysis, a number of patients and the cost for equipment and communication were found to be the key factors for influencing economic performance of telemedicine.

This paper conducted an analysis of economic effects of offshore wind power in Korea with benefit/cost analysis. The existing feed-on tariff, which was too low to support wind power development, was recently replaced with a Renewable Portfolio Standard(RPS), effective from 2012. According to the new regulatory policy, The Korean government has announced a strategy to draw investments worth for offshore wind farms with a total capacity of 2.5 GW over the next eight years, which is expected the change of cost and benefit. After overview the offshore wind power development status, The effects on cost can be divided by economic, environmental and social factors. Each factor will be calculated and combined by both evaluating index and using Quantification methods. At the end, the implication for the evaluation of feasibility of offshore wind power of Korea will be done.
