The traditional portfolio optimization problem is to find an investment plan for securities with reasonable trade-off between the rate of return and the risk. The seminal work in this field is the mean-variance model by Markowitz, which is a quadratic programming problem. Since it is now computationally practical to solve the model, a number of alternative models to overcome this complexity have been proposed. In this paper, among the alternatives, we focus on the Mean Absolute Deviation (MAD) model. More specifically, we developed an algorithm to obtain an optimal portfolio from the MAD model. We showed mathematically that the algorithm can solve the problem to optimality. We tested it using the real data from the Korean Stock Market. The results coincide with our expectation that the method can solve a variety of problems in a reasonable computational time.

This study is aimed at proposing the framework of international cooperation business in HRD KOREA. To achieve this goal I collected all of data that were used in process of international cooperation business in HRD KOREA and interviewed some people to get information from the people concerned. After that I analyzed data involved in using SWOT technique and proposed the framework of international cooperation business in HRD KOREA. The conclusions are as these. First, alliances must be vitalized between businesses besides between organizations. For example 'Developing of voluntary comeback program for foreigner' and 'Establishment of HRD KOREA Center' can be proposed as action plans for this strategy. Second, glocalization must be pushed ahead. For example 'Business career monitoring system for PMC' can be proposed as action plan. Third, building of preemptive base must be done. For example 'Standing of international HRD forum' can be proposed as action plan. Fourth, reinforcement of organizational competency must be done. For example 'The program for internationalization' can be proposed as action plan. Fifth, SBU(Strategic Business Unit) must be pushed ahead. For example 'Customer diversification portfolio' can be proposed as action plan.

Capital inflows have a strong presence that influences destination countries' development of institutions, which can in turn help resuscitate a stopped economy and re-attract capital that was lost during crises such as the recent public health crisis. While the previous literature emphasizes the mechanism that foreign investors press or even threaten the local government for change, this paper explores empirically whether institutional improvement can be achieved through the channel that host countries voluntarily reform institutions in anticipation of potential investments predicted by the exogenous geographical and cultural characteristics of the recipient countries. Given that countries with better institutional quality can accumulate larger FDI stocks, we still find that the need for more FDI, in contrast to FPI and debt, gives higher incentives to host countries to strategically improve their institutions before seeking capital overseas. Moreover, the predicted FDI exerts more prominent impacts on institutions on constraining elite than those involved in launching a business, enforcing contracts, and protecting properties. The results imply that a long-run plan for upgrading elite constraint institutions is crucial for a post-pandemic FDI reboot.

Companies are responding appropriately to the rapidly changing business environment and striving to lead those changes. As part of that, we are meeting our strategic goals through IT projects, which increase the number of simultaneous projects and the importance of project portfolio management for successful project execution. It also strives for efficient deployment of human resources that have the greatest impact on project portfolio management. In the early stages of project portfolio management, it is very important to establish a reasonable manpower plan and allocate performance personnel. This problem is a problem that can not be solved by linear programming because it is calculated through the standard deviation of the input ratio of professional manpower considering the uniformity of load allocated to the input development manpower and the importance of each project. In this study, genetic algorithm, one of the heuristic methods, was applied to solve this problem. As the objective function, we used the proper input ratio of projects, the input rate of specialist manpower for important projects, and the equal load of workload by manpower. Constraints were not able to input duplicate manpower, Was used as a condition. We also developed a program for efficient application of genetic algorithms and confirmed the execution results. In addition, the parameters of the genetic algorithm were variously changed and repeated test results were selected through the independent sample t test to select optimal parameters, and the improvement effect of about 31.2% was confirmed.

Purpose - This paper investigates the long term impact of RFID investment on firm value in Korea. We wand to find out why the long term performance of some firm's RFID investment is better than others. To understand the dynamics of the long term returns from RFID investment announcements, we divide our events into groups for each of the independent firm characteristic variable such as investment time period, kind of markets, industries, solvency and growth potential. We composed portfolios based on the RFID investment announcement date for each group and evaluate the monthly abnormal excess returns. Research design, data, and methodology - Based on these calendar-time portfolios, we measure the long term returns from 86 RFID investment announcements of 46 firms from 2003 to 2017. We construct the calendar-time portfolio for 3, 6, 9, 12 months of holding periods. Using the weighted least squares method, we regress the raw monthly returns of the portfolios on the Fama-French model and Carhart(1997) model. As a result, we can get the estimated risk adjusted mean monthly abnormal excess return α_P for each of the calendar-time portfolio. Results - We found that early adopters, large firms, non-manufacturing firms have very significant excess returns. We also found modestly significant excess returns for financially stable firms and slow growing firms. Put together, top managers of the firms which plan to invest RFID should understand the strategic role of RFID adoption and the generalized business process of distribution information technology investment in Korea. Moreover, the findings of this paper provide useful trading strategies to the managers of large funds who are considering on investing in RFID adopting firms. Conclusions - Put together, the results of this paper give us a new insight into how the RFID and IT technology in general and other characteristic factors' interactions affect the long term performance of firms. Using the unbiased estimates of long term returns of the calendar-time portfolios, this paper extends the understandings on short term impact of RFID adoption of existing studies. This paper also extends the current understandings of firm characteristics that affect the long term performance of RFID adopting firms.

21세기와 함께 고령화 사회로 접어든 우리사회의 전반적인 여건 변화는 그간 잠재수요로 내재되어 있던 유료노인주거시설에 대한 수요를 현실화시킬 것으로 기대됨에 따라 유료노인주거시설 시장은 새로운 투자 영역으로 부상할 전망이다. 한편, 현재 국내 건설사의 매출이 아파트 등 주거부문 건설에 집중되어 있어서 향후 경기변동에 따라 재무적 위험에 처할 가능성이 높으나 유료노인주거시설에 대한 투자와 이를 장기적으로 운영할 경우 고정적인 수입원을 확보할 수 있으므로 사업포트폴리오의 다양화 뿐만 아니라 재무적인 측면에서 안정성에도 기여할 수 있을 것으로 사료된다. 본 연구에서는 이와 같은 배경으로부터 유료노인주거시설 확충 시 투자자/운영자 측면에서 수익모델의 중요성을 인식하고, 건설사의 유료노인주거시설에 대한 투자 및 장기적인 운영이 매출액 및 영업이익에 미치는 영향을 분석함으로써 건설사의 사업다각화에 대한 가능성을 평가하였다.
