This study investigates the impact of Internet Banking Systems on the business performance of bank. Although Internet Banking Systems were introduced about 15 years ago in Korea, there were few studies which evidenced the relationship between Internet Banking Systems and the performance of banks. For this empirical investigation, this study collected the panel data of 13 domestic banks over 8.5 years and divided the dataset into two parts-the first half period (2003~2007) and the second half period (2008~2011) in order to examine the dynamic changes in the impact of Internet Banking Systems. The fixed-effects panel regression results were different in the two parts of dataset. Internet Banking Systems showed only cost-efficiency impact in the first half period. However, in the second half period, Internet Banking Systems showed positive impact on the bank profitability. Moreover, the dummy variable regarding local bank showed no additional impact on this result, implying that the impact of Internet Banking Systems was still significant for the local banks. The results will deliver managerial interpretation on the value of Internet Banking Systems and additional implication on the strategic planning of Internet Banking Systems for many domestic banks.

While ubiquitous healthcare (u-health) services were expected to propagate along with conventional healthcare services, recent progress indicated rather limited market acceptance. In this paper, we investigated the fundamental causes of why the consumer acceptance level of u-health services has been low. We draw upon innovation adoption theories to analyze the consumer readiness of the typical u-health services. The comparative analysis between innovative u-health services and conventional services was performed using analytic hierarchy process (AHP). Subsequently, policy and business implications including technological breakthrough insights were discussed based on the customer perspective comparative adoption analysis. The propositions captured through this study provide useful insight to further studies on u-health services.

In recent years there has been an increasing amount of attention paid to outosourcing of information systems (IS) functions in organizations. The changing and more strategic role of outsourcing in business firms has been given much coverage in academic and trade publications. Trying to remain competitive and up-to-date in the rapidly developing world of computer technology is becoming a financial burden to many organizations in fields such as banking and financial services, health care, and manufacturing. Hiring outsiders to handle part or even all of its information services helps an organization provide better services and maintain a competitive advantage. This paper attempts to provide a benchmark of current IS outsourcing utilization in Korea. A detailed descriptive analysis of survey responses from 78 Korean companies indicates the usage, length of experience, expenditure of outsourcing, and kinds of IS functions being outsourced. The study also analyzes the effects (strategic, economic, and technological) of IS outsourcing with respect to the length of experience, expenditure of outsourcing, and kinds of IS functions being outsourced As a result of the analysis there are significant differences in the strategic, economic and technological effects of IS outsourcing with respect to the expenditure of outsourcing, kinds of IS functions being outsourced and firm size.

The drone is an unmanned aerial vehicle which has no human pilot. Drones can be classified into military drones, commercial drones, and personal drones by usage. Also, drones can be classified from large-sized to nano-sized drone by size and autonomous, remote controlled drone by control type. Especially, military drones can be classified into low-altitude drones, medium-altitude, and high-altitude drones by altitude. Recently, the drone industry is one of the fast growing industries in the world. As drone technologies have become more advanced and cost-effective, Korean government has set its goal to become a top-level country in drone business. However, the government's strict regulation for drone operations is one of the biggest hurdles for the development of the related technologies in Korea and other countries. For example, critical problems for drone delivery can be classified into technical issues and institutional issues. Technical issues include durability, conditional awareness, grasp and release mechanisms, collision avoidance systems, drone operating system. Institutional issues include pilot and operator licensing, privacy rules, noise guidelines, security rules, education for drone police. This study analyzes the trends of the drone industry from the viewpoint of technology and regulation. Also, we define the business areas of drone utilization. Especially, the drone business types or models for public sector are proposed. Drone services or functions promoting public interests need to be aligned with the business reference model of Korean government. To define ten types of drone uses for public sector, we combine the business types of government with the future uses of drones that are proposed by futurists and business analysts. Future uses of drones can be divided into three sectors or services. First, drone services for public or military sectors include early warning systems, emergency services, news reporting, police drones, library drones, healthcare drones, travel drones. Second, drone services for commercial or industrial services include parcel delivery drones, gaming drones, sporting drones, farming and agriculture drones, ranching drones, robotic arm drones. Third, drone services for household sector include smart home drones.

Recently, the development of wireless network technologies has been advancing in several directions: increasing data transmission speed, enhancing user mobility, expanding the range of services offered, improving the utilization of the radio frequency spectrum, and enhancing the intelligence of network and subscriber equipment. In this research, a series of contradictions has emerged in the field of wireless network technologies, with the most acute being the contradiction between the growing demand for wireless communication services (on operational frequencies) and natural limitations of frequency resources, in addition to the contradiction between the expansions of the spectrum of services offered by wireless networks, increased quality requirements, and the use of traditional (outdated) management technologies. One effective method for resolving these contradictions is the application of artificial intelligence elements in wireless telecommunication systems. Thus, the development of technologies for building intelligent (cognitive) radio and cognitive wireless networks is a technological imperative of our time. The functions of artificial intelligence in prospective wireless systems and networks can be implemented in various ways. One of the modern approaches to implementing artificial intelligence functions in cognitive wireless network systems is the application of fuzzy logic and fuzzy processors. In this regard, the work focused on exploring the application of fuzzy logic in prospective cognitive wireless systems is considered relevant.

This study presents the growth strategy of outsourcing service by finding out the differences of importance between user firms and system integration(SI) firms in Korean outsourcing business, The result of data analysis reveals that there are siginificant differences between user firms and SI firms in some components of information systems(IS) outsourcing services. User firms regarded integation of distributea data centers as the prominent issue of IS environment changes. Meanwhile, SI firms chose management of IS/VAN center, office automation(OA), and management of global network, as the more important issues in the application area of outsourcing. Among the merits of outsourcing, both of them considered cost reduction and IS flexibility as the most important factors, However, they chose the difficulty of management control and the lack of operation knowledge among the demerits of outsourcing, Also, they commonly selected overall IS consulting among the components of outsourcing diffusion. In the question of future outsourcing services, user firms chose the adoption of client/server architecture, while SI firms selected the application of multimedia. These results show that there are some differences of preference between user firms and SI firms. Most of user firms consider the outsourcing to maximize information utilization, while the service suppliers focus on new IT adoption and its application to organization. For the strategic use of outsourcing services, SI firms are required to establish the diffusion strategy to meet the outsourcing needs of user firms.
