This study deals with a strategic decision making in two level supply chain network design. This study presents more realistic mathematical model than the previous studies by considering simultaneous location of plants and distribution centers, determination of capacity level for both plants and distribution centers, and upper limit condition for numbers of locating plants and distribution centers. This paper tries to help the strategic decision making for two level supply chain network design. For this purpose, three different sized numerical examples are generated and optimal solutions are obtained by applying Excel Solver program. And sensitivity analysis is performed for the biggest sized example problem, which has 10 potential plants, 20 potential distribution centers, and 200 customer zones. After the plants being located are fixed, optimal minimum costs are obtained and compared for each of 7 different numbers of distribution centers to be located. As the number of distribution centers increases, changes in inbound transportation cost and outbound transportation cost can be derived. In case of considering cost as well as customer satisfaction level for two level supply chain network design, the analysis of this changes may help more sophisticated decision making.

As cloud services and deployment models become diverse, there are a growing number of cloud computing selection options. Therefore, financial companies need a methodology to select the appropriated cloud for each financial computing system. This study adopted the Balanced Scorecard (BSC) framework to classify factors for the introduction of cloud computing in financial companies. Using Analytic Hierarchy Process (AHP), the evaluation items are layered into the performance perspective and the cloud consideration factor and a comprehensive decision model is proposed. To verify the proposed research model, a system of financial company is divided into three: account, information, and channel system, and the result of decision making by both financial business experts and technology experts from two financial companies were collected. The result shows that some common factors are important in all systems, but most of the factors considered are very different from system to system. We expect that our methodology contributes to the spread of cloud computing adoption.

The purpose of this study is to find out specific measures that can help the management strategy of patient-centered medical institutions by conducting research on patient experience surveys of convergence outpatient medical services using data mining techniques according to changes in patient-centered medical culture. Using the raw data of the 2018 Medical Service Experience Survey, 8,843 people over the age of 15 who had patient experience in outpatient medical services were analyzed. Decision tree analysis was performed. The determinants of satisfaction with outpatient medical services patient experience were the doctor's area and patient's rights protection area, and the determinants of intention to recommend outpatient medical services were the doctor's area and facilities comfort. Women evaluated the experience positively in overall satisfaction as compared to men, and those over the age of 60 positively evaluated the overall satisfaction and intention to recommend. It is significant that the outpatient experience decision-making model is presented, and that the doctor's area, patient's rights protection area, and facility comfort are important factors. Long-term research on the 'Medical Service Experience Survey' is needed, and research on the inpatient medical service experience is needed.

The information technologies industry is now experiencing a rebirth of strong stable growth. However, very few studies have examined performance implications of strategic alliance or merger and acquisition from a knowledge-based view. Furthermore, none of these studies have investigated resource complementarities and alliance or merger and acquisition motive as potential sources of firm performance. This paper extends upon current knowledge-based literature to discover and explore linkages between resource complementarities and firm performance of strategic alliances or merger acquisitions. This study finds that strategic alliance and merger and acquisition announcements have provided abnormal positive returns of production alliances and merger and acquisition. This study can be used as a stepping stone for selection of strategic alliance or merger and acquisition.

This paper examines the impact of the strategic leadership of CEOs after M&A on resistance to change and on perceived performance. Most M&A research has focused on the strategic, financial and economic aspects, while studies on leadership and employee behavior have been limited. CEO leadership is critical to a successful M&A. Recently, strategic leadership has been attracting more attention. Strategic leadership can be defined as a person's ability to anticipate, envision, maintain flexibility, think strategically and to work with others to initiate changes that will create a viable future for an organization. It can also reduce resistance and improve perceived performance. So this paper used empirical studies from the IT industry after M&A.

This case study explores the stock sale, the resulting governance structures, and the airport management and development in Beijing Capital International Airport and Shanghai International Airport at Pudong. It is imperative for Incheon International Airport Corporation (IIAC) to change the management paradigm to survive in the changing environment and to become hubs in the relevant regions. And IIAC needs to search for the new ownership and governance structure to cope with the internal and external demands for innovation. In this study, along with the recent trends of the global airport industry, we suggest the implications for the IIAC's major decisions, especially, for the stock sale, the resulting governance structure, and the airport development and management. It is suggested that Korean government retain the majority control in the process of privatization to keep IIAC as a government-owned enterprise to provide the public goods to the citizen. Furthermore, to maximize the value of stock sale, IIAC needs to decide strategically the time and speed in the hybrid form of stock selling using trade sale and IPOs.

Although cryptocurrency which can promote innovation in the blockchain ecosystem is published for many useful purposes, in Korea, cryptocurrency is recognized only as a means of investment for the profit. The fact emphasizes only the speculative nature of the cryptocurrency, so investor negates the fundamental purpose of cryptocurrency and hinders innovation in the blockchain ecosystem. The purpose of this study is to investigate the cause of cryptocurrency perception and speculative behavior of domestic cryptocurrency investors from an academic perspective. We use a model that reflects the traditional considerations and cryptocurrency's characteristics in investment. Using the model, we can explain the cause of misperception of cryptocurrency through the theory of bounded rationality. In building the research model, we use variables of venture and angel investor's consideration used in investment decisions and collect the keywords from indexes of whitepaper to reflect the properties of cryptocurrency. This study mentions that, due to the imitations presented by Simon, individuals are forced to perceive cryptocurrency as a means of speculation and to make irrational decisions that impair ecosystem health. We analyze whether there is a significant difference in rationality in decision made by the sample under limited knowledge and imperfect information constraints. As a result, imperfect information constraints led investors to consider only irrational criteria in decision making. From this result, this study suggests that information asymmetry needs to be relaxed so that investment can be pursued together with rational investment and development of blockchain ecosystem. In addition, the industry can capture strategic insights for successful financing through ICO by enabling better understanding of investor decision-making.
