Recently real-estate investment business is standing out as a new plan for creation of source of income. In this paper, we suggested appropriate real-estate investment strategy through the reconstruct case study of existing one-storied building. That is, we showed the efficient process of decision and propel to reconstruct and the key points for lease business and post management after building completion. Also, we analyzed the rate of return of commercial building investment in order to find its optimum dealing time. Therefore the results of this paper are expected to be a help to old ages and persons laying plans for a similar business.

A capital investment problem is essentially one of determining whether the anticipated cash inflows from a proposed project are sufficiently attractive to invest funds in the project. The net present value(NPV) criterion and internal rate of return(IRR) criterion are widely used as means of making investment decisions. A positive NPV means the equivalent worth of the inflows is greater than the equivalent worth of outflows, so, the project makes profit. Business people are familiar with rates of return because they all borrow money to finance ventures, even if the money they borrow is their own. Thus they are apt to use the IRR in preference to the NPV. The IRR can be defined as the discount rate that causes the net present value of a cash flow to equal zero. Why the project are accepted if the project's IRR is greater than the investor's minimum attractive rate of return\ulcorner Against the NPV, the definition cannot distinctly explain the concept of the IRR as decision criterion. We present a new definition of the IRR as the ratio of profit on the invested capital.

This paper aimed at identifying rural amenities valuable in terms of marketed value and economic analysis of green tourism so as to develop policy instruments for new rural communities. We conducted the case study on Jik-Dong rural community in Taejeon city and estimated income effects of green tourism and internal rate of return of investment for rural amenity facilities. The research results are as followings; (1) green tourism participant will spend the worth of 50,392 won per person, (2) earnings from green tourism amounts to about 2,471 thousand won per household, (3) internal rate of return of green tourism investment is estimated as 7%. The strategies far green tourism is suggested as follows; (1) rural amenities should be well maintained for green tourism infrastructure (2) measures to internalize the value of rural amenities should be developed for market oriented peen tourism (3) effective program for inducing visitors with purchasing power should be designed.

Recent collapse of shipping market right after unprecedent surge clearly demonstrates that shipping industry is extremely risky. Due to the volatile movements of the freight rates, investors tend to ask higher rate of return; higher required return reduces the total net present value of the investment project. For several decades, the Discounted Cash Flow(DCF hereafter) analysis has been the most frequently used valuation technique. However, the main problem of the DCF analysis is its assumption that the discount rate would stay the same during the project life. In other words, it usually does not address the decisions that managers have after a project has been accepted. The purpose of this study is investigate a new valuation method of investment: the Real Option Analysis(ROA hereafter) on ship investment. By replacing the existing valuation methods with the new one, the research will present a new perspective on investment with uncertainty. While uncertainty increases risk of investment and consequently discounts the value of it in the traditional feasibility analysis, in the ROA, a new valuation method which will be addressed in the research, uncertainty means some additional value of flexibility so that the tool can help investors produce more accurate decisions. Contrary to the DCF analysis, the ROA takes managerial flexibilities into account. In reality, capital budgeting and project management is typically dynamic, rather than static in nature. The ROA finds and assesses the values of managerial flexibilities or real options in the investments. The main structures of the research will be as follows: (1) overview of the ship investment project, (2) evaluation of the project by the Net Present Value analysis, (3) evaluation of the same project by the Real Option Analysis, (4) comparision of the two techniques.

국제적인 지구환경 보호문제 및 에너지의 효율적인 활용이라는 측면에서 다른 발전시스템 보다 월등하게 효율이 높은 열병합발전시스템은 개발 및 실용화되고 있는 실정이다. 본 논문에서는 이와 같은 열병합발전시스템을 모 호텔에 도입하는 경우 기존의 열 및 전기공급 방법의 요금과 신규로 열병합을 도입하였을 경우의 열 및 전기요금의 차액을 계산하고 신규투자비를 고려하여 단순 투자비 회수를 토대로 도입에 대한 경제성을 분석하였다. 열병합설비의 투자비 회수기간은 약 10년 정도로 10년 이후에는 열 및 전기요금의 혜택을 볼 수 있으므로 도입 가치가 충분히 있으며, 이자율 하락이나 정량적으로 계산하기 어려운 환경문제 개선비용 및 전기요금의 증가를 고려하면 실제적으로는 더욱 경제성이 있음을 알 수 있다.

When a company makes a decision on an investment for a new product as a source for a new program, it is not easy for them to take a proper decision-making process in this highly volatile market. There could be several ways to make an investment decision on a new program. A company needs to choose the most suitable way of investment which is reflected current corporate circumstances and potential risks. We check up the process of the engineering economic decision in a automotive part manufacturing company. We define the gap between the theory and practice on engineering economic decisions. We present advices to make a decision desirably.

본 연구는 신주인수권부사채(BW)의 투자효율성이 투자자 입장에서 어느 정도 인지를 규명하고 투자자들에게 효율적인 투자방안을 제시하는 것이 연구목적이다. 연구방법은 2014년부터 2021년 7월까지 발행한 BW에 대한 표면이자율, 만기이자율, 발행일, 권리행사 시작일과 종료일, 만기일, 행사가액 등을 조사한 후, 행사시작일 이후에 발행회사의 일별 주가등락과 연결하여 BW에 대한 투자의 효율성과 신주인수효과를 계량적으로 파악하고자 하였다. 연구 결과, 행사가액초과일수비율이 신주인수 가능날짜의 41.3%로써 신주인수권부사채의 투자효율성은 높지 않은 것으로 분석되었다. 행사시작일 수익률은 평균 24.8%, 종료일 수익률은 평균 52.6%로써 평균적으로 플러스 수익률을 보여서 투자자 기대에 맞게 도출되었다. 행사시작일 수익률이 마이너스인 종목 수가 플러스인 종목 수 보다 1.47배 많았으며, 종료일수익률이 마이너스인 종목 수가 플러스인 종목 수 보다 1.16배 많아서 신주인수 기대수익률은 발행종목에 따라 편차가 큰 것으로 분석되었다.
