This study seeks to analyze trends in Korean government support for marine biotechnology R&D investment. The quantitative analysis proposed in this paper provides useful data to inform government policy making decisions in relation to R&D investment in the marine biotechnology. Data used in this study is from NTIS (National Science & Technology Information Service) DB. Empirical results indicate that national R&D investment in the area of marine biotechnology has recently been increased in terms of the number of R&D programs and the amount of R&D investment. The results also show that the R&D programs in the area of marine biotechnology involve various Ministries of the government of Korea, although the Ministry of Oceans and Fisheries (MOF) performed a key role in the R&D investment in the marine biotechnology. Finally, the results of social network analysis in this study reveals that most of the R&D programs in the area of marine biotechnology seeks the development of new materials using unique features of marine bioresources.

What benefit items from railroad investment are evaluated, and how those items are quantified have profound impacts on the feasibility of the proposed investments. They also have implications on the projects priorities, not to mention on intermodal comparison between highway and railroad. Evaluation procedures currently being utilized in Korea show limits in fully evaluating railroads' investment impacts. Economic and practical implications are evaluated for including revenues for railroad investment. Based on the critical evaluation of procedures in other countries, and based on the analysis of Korea's national transportation goals, new and improved benefit items are redefined and quantification guidelines are proposed.

본 연구는 주식의 격언이 주식 투자자의 투자 행동에 영향을 미치는 지에 대한 연구로서 주식 시장에서 오랜 시간 사용되어 온 주식 격언을 투자자들이 알고 있는 지를 확인하고, 주식 투자자가 이러한 내용을 실제 투자 과정에 적용 하는지 그리고 그 적용이 투자 성과에 영향을 미치는 지를 분석하였다. 이를 위하여 본 연구에서는 주식시장에서 활용되고 있고, 주식과련 문헌에 자주 인용되는 투자 원칙, 분산 투자, 종목 선정, 매수 매도 시점 및 주가 동향에 관한 총 29개의 주식 격언을 선정하여 191명의 주식 투자자들에게 설문 조사를 실시하고 그 결과를 분석하였다. 분석 결과 14%의 투자자들이 주식 격언을 적용하여 투자하고 이를 통하여 수익을 창출하는 것을 확인하였다. 본 연구 및 결과를 통하여 주식 시장과 주식 투자자들이 분석된 주식 격언 통계를 활용하여 주식 투자에 적용하여 도움 되기를 기대한다.

This paper aims to determine factors causing the stagnation of Korean firms' fixed investment after the global financial crisis, using panel data for the period of 1999-2016. Fixed investment remained sensitive to cash flow and Tobin's q although their effects decreased after the global financial crisis. A decreasing trend of cash flow and an increase in Tobin's q since the early 2000's imply that the worsening cash flow was a major factor behind the sluggish investment after the crisis. Meanwhile, debt-equity ratio remained significant for non-chaebol affiliated firms, reflecting disparity in access to external financing. Volatility of stock returns also became insignificant after the crisis, casting doubt on the argument that uncertainty was a major factor contributing to the decline of fixed investment. Analysis of financial investment confirmed the significant effect of cash flow, larger than that on financial investment than on fixed investment. In particular, debt repayment and other financial investment, except share repurchase, were sensitive to cash flow. However, the substitution of fixed investment by financial investment is a consequence, rather than a cause of declining fixed investment.

본 연구에서는 투자자 거래 정보를 활용한 포트폴리오 투자전략을 제안했다. 포트폴리오를 구성하는 과정에서 군집분석을 활용하여 기대수익이 높은 종목을 선정하고, 유전자 알고리즘으로 포트폴리오를 최적화하여 투자성과를 높이고자 했다. 2007년 4월부터 2013년 6월까지의 국내 주식시장을 대상으로 한 실증분석을 통하여, 본 연구에서 제안한 포트폴리오 투자전략의 유용성과 우수성을 확인 했다. 본 연구의 결과는 특정 투자 주체의 매매행태를 분석하여 투자 의사결정에 이용할 수 있으며, 이를 통하여 높은 투자성과를 얻을 수 있음을 보여준다. 또한 인공지능 기법이 투자 의사결정에 유용하게 사용될 수 있음을 시사한다.

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.

This paper suggests a valuation framework of investment project using the concept of real options. We show the valuation process of real assets using the risk-neutral pricing. Especially, we focus on the investment lag. Real assets have investment lag in general. The decision time and the payment time are not identical. So the investment lag should be considered when valuing real assets for reality. We provide the valuation process for real assets, including R&D project. The results of this paper can be used for the real assets valuation and strategic decision analysis.

The investment for industrial disasters prevention can not help but get accomplished in negative way. At this point, the most effective way to diminish industrial disaster outbreak is the very subject should strive to prevent it by itself However, it's still the times that we place more weight on economic development no economic subject would not positively self-participate in it for the investment for industrial disasters prevention without my effect of numerical reduction. In this view, this study will tv to entirely analyze and grasp the economic toss due to industrial disasters at construction sites, and will present the most suitable safety-investment. As a result, in domestic construction sites, averagely $1.6\~2.6\%$ of the entire construction expenses had been invested for safety expense. The according to the result of the analysis, basically this safety investment expenses should be spent $2.4\%$ over to reduce the saffey-accidents stably.
