본 연구는 북한경제관련 전문기관이나 전문가들의 연구결과와 불완전하게나마 발표되거나 간접적으로 도출된 북한의 통계자료들을 통계학적인 방법으로 통합하여 에너지 부문이 구분된 북한의 2005년도 산업연관표를 추정하였다. 이렇게 추정된 산업연관표를 이용하여 에너지 부문에 대한 대북투자가 북한경제의 산업별 산출과 부가가치에 미치는 효과를 투입-산출 분석과 CGE 분석을 이용하여 계산하였다. 전력산업에 대한 40억 달러의 대북투자는 총산출을 3억 6,802만 달러 증가시키고 총부가가치를 1억 5,599만 달러 증가시키는 것으로 계산되었고 석유산업에 대한 1.5억 달러의 대북투자는 총산출을 2,046만 달러 증대시키고 총부가가치를 965만 달러 증가시키는 것으로 나타났다.

본 연구에서는 종합주가지수와 코스닥지수, 문화콘텐츠 산업과 관련이 높은 오락 문화, 디지털콘텐츠 지수를 이용하였다. 지난 2004년 3월에서 2015년 7월까지 총 597주 동안 각각의 주가지수 및 수익률 동향을 파악하였다. 각 주가지수의 수익률, 변동성, 상관관계, 동조화현상 등을 비교 분석하여 콘텐츠관련 주식들이 투자가치가 있는지 살펴보았다. 향후 문화콘텐츠 산업의 높은 성장 가능성을 보았을 때 관련 주식들의 투자 가능성에 기대를 걸어보았다. 분석 결과 지난 2008년도 글로벌 금융위기 이후 문화콘텐츠 관련 주식들이 더 높은 상승률을 보여주었다. 최근 문화콘텐츠 산업에 대한 관심이 높아지면서 점점 투자가치 메리트가 증가하고 있음을 볼 수 있었다. 향후 문화콘텐츠 산업이 계속 발전할 것으로 예상되어 이들 기업에 대한 투자자들의 많은 관심이 이어지면서 문화콘텐츠관련 기업들의 투자가치 상승에 많은 기대를 걸어본다.

A nuclear power plant requires a huge amount of initial investment and long construction lead time. As we expect that there may exist a relationship between investment and construction lead time, a number of researchers have reported that nearly a half of investments is incurred due to time factors such as the time value of money and inflation or escalation rates. Therefore, we investigated in this paper a relationship between the initial investment and the construction lead time of a nuclear power plant construction, and proposed a method for a trade-off analysis between the annual equivalent worth and the investment alternatives to reduce the construction lead time. Finally, we presented a real case to numerically explain the steps of the method presented in this paper.

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. 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.

본 연구에서는 철도 투자에 따른 투자이후 수요변화를 계량화하기 위한 조사방법론을 검토하도록 한다. 특히, 유발수요는 전환수요에 비해 조사 및 계량화 방안에 대한 연구가 미흡하므로 유발수요를 중심으로 조사 및 계량화방법들을 검토하여 제시하도록 한다. 이러한 연구 결과는 국내에 철도에 대한 투자이후 단계에서 수요변화를 추정하는 연구가 미흡한 실정이므로 향후 활용도가 높을 것으로 판단된다.

The IRR (internal rate of return) is often used by investors for the evaluation of engineering projects. Unfortunately, it is widely known that it has serial flaws. Also, External rate of returns (ERRs) such as ARR (Average Rate of Return) or MIRR (MIRR, Modified Internal Rate of Return) do not differentiate between the real investment and the expenditure. The PRR (Productive rate of return) is faithful to the conception of the return on investment. The PRR uses the effective investment instead of the initial investment. In this paper, we examined two cases of the engineering project. the one is a traditional engineering project with financing activity, another is the project with R&D. Although the IRR has only one value, it overestimates or underestimate profitabilities of Engineering Projects. The ARR and the MARR assume that a returned cash reinvest other projects or assets instead of the project currently executing. Thus they are only one value of a project's profitability, unlike the IRR. But the ARR does not classify into the effective investment and non-investment expenditure. It only accepts an initial expenditure as for an investment. The MIRR also fails to classify into the investment and the expenditure. It has an error of making a loss down as the investment. The IRR works as efficiently as a NPW (Net Present Worth). It clearly expresses a rate of return in respect of an investment in an engineering project with a loan. And it shows its ability in an engineering project with a R&D investment.

This paper develops a portfolio management game applicable to Korean Stock Market with an emphasis on teaching and training aid. It allows each participant to start out with a certain amount of money and pick his favorable stocks from a list of stocks chosen by instructor. Each participant must make a transaction at each time period and he gets a readout that states his individual performance, i.e., stock lists, cash on hand, net worth, transactions he has made and rank in accordance with his net worth. This game package consists of 10 subprograms and 7 files written with Fortran language for use on the Nova 840 computer and is divided into 3 main categories according to their functions, i.e., book-keeping function, data processing function and information searching function. This package may be used for training portfolio decison makings in the stock market and for comparing various investment methods through hypothetical investments.

This study analyzed and suggested management situations and improving issues on a consumer cooperatives which has supplied environmentally friendly agricultural products from the year 2002. Indices of management analysis are stability ratio, activity ratio and profitability ratio. Management Stability ratio indices are debt ratio, net worth ratio, fixed ratio and current ratio. Management activity ratio ones include fixed assets turnover and net worth turnover. And profitability ratio is showed through return on investment, net return on sales and return on equity. In order to analyze these indices, financial statements after the closing entires are used each year.

This study analyzed the management situation of two organizations that have produced environmentally friendly agricultural and livestock products. One organization sells and processes environmentally friendly agricultural products like as grains, vegetables, fruits and processing foods. Another organization processes and sells environmentally friendly livestock products, specially beef products. Indices of management analysis are stability ratio, activity ratio and profitability ratio. Stability ratio indices are debt ratio, net worth ratio, fixed ratio and current ratio. Activity ratio ones include fixed assets turnover and net worth turnover. And profitability ratio is showed through return on investment, net return on sales and return on equity.
