R&D is the core competence of an enterprise. Furthermore, R&D requires huge capital investment and has very risky characteristics. Therefore, to be successful in R&D process, several approaches of engineering economics are used prior to decision-making. Until now, typical approaches of engineering economics such as NPV(net present value) or DCF(Discounted cash flow) have been used. But, they cannot properly capture managerial flexibility to adapt and revise later decisions in response to unexpected market development. In a constantly changing and always uncertain marketplace, managerial operation flexibility and strategic adaptability have become vital in order to successfully capitalize on favorable future investment opportunities and limit losses from adverse market development. For the alternatives of conventional static decision-making approaches, new concept of using real options is introduced. Real option theory is based on financial option's characteristics and checks every revision interval whether situation have changed favorable to decision maker or not. In advantageous situation, the decision maker has only to go on. In contrast, with unfavorable situation, he abandons the investment immediately. In this aspect, real option model is more suitable in very uncertain and dynamic business environment in that it can provide the opportunity to cope with flexibility. This paper suggests efficient and effective R&D investment strategy by using real options model. In addition, this paper compares financial options and real options.

전통적 투자안 평가방법인 현금할인법(DCF:discounted cash flow) 모형의 투자안 평가는 경영자가 미래 사업환경의 변화에 능동적 대처를 할 수 없다는 가정이다. 그러나 현실에서는 투자를 수행하는 중에 새로운 정보가 유입되고 불확실성이 클 때 평가 시점에서 예측한 대로 시나리오가 이루어지기 어렵기 때문에 경영의 유연성을 고려하는 실물옵션 방법으로 평가함으로써 이런 난점들을 극복할 수 있다. 실물옵션에는 연기옵션, 단계적 투자옵션, 변경옵션, 포기옵션, 전환옵션 등이 있다. 따라서 사업 변동성이 클 경우 전통적인 DCF보다는 이러한 변동성이 갖는 가치를 적극 이용하여 평가하는 실물옵션 방법이 보다 바람직한 평가방법이라 할 수 있다.

Under climate change and urbanization, rainwater harvesting (RWH) systems are emerging as an alternative source of water supply because of growing concern about water sustainability. RWH systems can satisfy the various watering needs and provide the environmental benefits of lessening the damages from flood, drought, and runoff. The economic success of a RWH system is vitally concerned with the determination of the design capacity of storage tank to be built in the system. The design capacity is determined by the factors of average annual rainfall, period of water scarcity, and water price during the whole life-cycles. Despite the high uncertainties inherent in these factors, the current engineering design of RWH system construction often assumes that storage tanks should be built all at once. This assumption implicitly ignores the managerial flexibility in responds to the future as new information comes out-the right to build storage tanks stage by stage depending on the evolution of demand. This study evaluates the value of a multistage storage tank construction using a real option approach. A case study involving a typical RWH system construction in Jeonju, the Republic of Korea is conducted. The managerial flexibility obtained from the real option perspective allows engineers to develop investment strategies to better cope with the issue of water sustainability.

The purpose of this study was to explore the effect of creativity management factors on R&D performance. To do this, the data(885 cases) was collected from 19 Korean Government-supported Research Institutes, and 3 hypothesis derived from model of creativity management(after here CM) were tested. Major findings are as follows: 1) CM factors are grouped into diversity, autonomy, connectivity, redundancy and flexibility factors; 2) The factors that can explain R&D performance are connectivity, autonomy, diversity and flexibility factors; 3) All CM factors have significant relationship with satisfaction of the employees; 4) Flexibility and connectivity factors give effects on turnover intention of the members. This study has some limitations in model building and empirical testing. But this study provided the theoretical and managerial implications about CM and R&D management, especially Government-supported Research Institute.

The purpose of this study is to explore the effect of creativity management factors on perceived R&D performance. To do this, the data (885cases) were collected from 19 Korean Government-supported Research Institutes, and 3 hypotheses derived from the model of creativity management(after here CM) were tested. Major findings are as follows: 1) CM constructs are grouped into diversity, autonomy, connectivity, redundancy and flexibility factors; 2) The major factors that can explain R&D performance perceived by scientists and engineers are connectivity, autonomy, diversity and flexibility; 3) All CM factors have significant relationship with satisfaction of the employees; 4) Flexibility and connectivity factors give effects on turnover intention of the members. This study has some limitations in model building and empirical testing. This study, however, provides theoretical and managerial implications about CM and R&D management, particularly Government-supported Research Institutes in Korea.

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.

의료조직 경영에 대한 기존의 연구들은 의료서비스의 품질 혹은 운영의 효율성을 위한 연구에 집중된 반면에 본 연구는 조직운영의 중요한 전략적 요소인 유연성이 의료조직의 경영에 어떠한 영향이 있는지를 연구하였다. 특히 의료조직의 수량유연성과 제품유연성을 대상으로 이들 유연성의 원천이 되는 내부 및 외부 자원의 활용이 조직의 재무적 성과에 미치는 영향을 분석하였다. 국내 병원들을 대상으로 표본을 추출하였고, 설계된 설문지를 이용하여 연구변수들의 측정 자료를 수집하였다. 연구변수들의 관계를 가정한 가설을 검정하기 위하여 회귀모형을 수립하고 분석한 결과 내부자원에 기반한 수량유연성이 성과에 직접적으로 영향을 줄 뿐 아니라 제품유연성의 내부자원 및 외부자원의 활용과 상호작용을 통해서도 성과에 영향을 주는 것으로 나타났다. 반면에 외부자원에 의한 수량유연성은 조직성과에 유의적인 영향이 없는 것으로 나타났다. 이들 분석결과에 대한 설명과 관리적 시사점을 논의하였다.

This research examined the mediation effect of Workforce Agility (WA) on the relationship between environmental uncertainty and operational performance. We manipulated the control variables that are known to be affected by employment flexibility. Employment flexibility is caused by idiosyncratic characteristics of Korean port system. The analysis was tested by Baron & Kenny's method. The result indicates that each path of the proposed model is significant. Furthermore, the mediation effect was checked with the Sobel Test. The research revealed that environment uncertainty poses an indirect effect on operational performance. Both supply/demand uncertainty and technological uncertainty affected operational performance through the mediation effect of WA. Most of the distribution centers located in Busan Newport Distripark are operated in a bimodal labor (human resource) system which includes both permanent employees (workers) and temporary employees (workers). This empirical research provides theoretical and managerial implications by suggesting ways to increase efficiency in distribution center operation through WA enhancement, and to improve the unloading labor system.
