In the situation where the uncertainty of the environment of organizations is high and dynamic, the competitive advantage should be secured and maintained through securing knowledge-based intangible assets rather than tangible assets. human resources management in the service industry is more important than in any other industries. Accordingly, based on preceding researches, this study examines the adoption factors and the results of organizations with regard to the e-HRM system as IT-based information system. The proof results are summarized as follows. First, the degree of IS maturity in the information technology factors was found to have effects on the business results of organizations (financial and non-financial results) and the IS/IT based structure was found to have significant effects on financial results (productivity, growth potential) but no effects on non-financial results (revitalization of organizations, the degree of total satisfaction). Second, the degree of competition, the degree of information technology and environmental uncertainty factors in environmental factors were found to have effects on financial results (productivity, growth potential) but no effects on non-financial results (the revitalization of organizations, the degree of total satisfaction). Third, it can be seen that the scales of organizations partially play the adjustment role between information technology factors and environmental factors and the business results of organizations. Based on these results, we can cautiously draw the conclusion that it is effective in enhancing financial results (productivity, growth potential) of organizations to adopt the e-HRM system in the case of large scale organizations in the service industry.

The stability and security management of IT data becomes more important because information security threats increases rapidly in Big Data era. The operational policy of the data backup considering information security threats is required because the backup policy is the fundamental method that prevents the damage of security threats. We present an economic approach for a data backup system with information security threats which damage the system. The backup operation consists of the differential backup and the batch backup. We present a stochastic model considering the occurrence of information security threats and their damage. We analyze the stochastic model to derive the performance measures for the cost analysis. Finally we analyze the average cost of the system and give numerical examples.

One of the hottest issues of security is information leakage of financial institution. Financial institutions including commercial banks are frequently threatened by attempts of leakage through hacking and vulnerability, and this information is centered on personal information of their clients. Through this study, I found out that security managers of financial institutions are trying to prevent the leaking of private information, but in fact most of them barely know where their personal information is. Even if they know where it is and trace the data, it is often found in unexpected places. Because there is a lot of waste in time and human resources as search is done manually, we have understood that responding to IT Compliance requires a lot of effort. This study is to improve IT Compliance response and protect information leakage through monitoring PC and servers, the main storage of personal information by automated system, periodically.

Information is a valuable asset regardless of the size of the enterprise and information security is an essential element for the survival and prosperity of the enterprise. However, in the case of large corporations, Security is ensured through rapid introduction of information security management system. but In the case of SMEs, security systems are not built or construction is delayed due to complex factors such as budget constraints, insufficient security guidelines, lack of security awareness. In this paper, we analyze the actual situation of information security management of SMEs through questionnaires, and We would like to suggest a comprehensive security plan for SMEs in free or inexpensive ways. We believe that by applying the method presented in this paper, SMEs will be able to implement the lowest cost basic information security and will benefit SMEs who plan to establish an information security plan.

The average age of CEOs of the small and medium-sized enterprises(SMEs) in Korea is 58.8, and discussions are actively underway regarding the support towards the succession companies. Government authorities are also operating a system to support the succession companies, and recently global support is also being demanded. In order to have justification over the support for succession companies, the fact that it greatly contributes to the revitalization of the national economy and the regional economy must be acknowledged in advance. This study analyzed the degree of corporate succession revitalization of the national and regional economy through statistical and empirical analysis. With the purpose to secure the reliability of the analysis, the study has referred to the database of the "Integrated Management System for Small Business Recruitment Project" and the Korea Enterprise Data (KED), which can be the most differentiated aspect compared to the existing research of the past. According to the analysis, it shows that the old companies' performance is significantly higher than the general companies in terms of sales, number of employees, assets, and operating profits⋯etc. The management performance of the old companies (which lasted over 30 years) more than doubles the performance of the start-ups (with less than 10 years of experience) in sales, triples the number of employees, doubles the assets, and more than doubles the operating profit. Thus, it is seen that the contribution to the overall economy is significant. Additionally, as a result of the empirical analysis of the relationship between the regional old companies and the regional economic revitalization, the non-metropolitan area shows better performance than the metropolitan area in terms of the number of employees, assets, borrowings, and rent, which entails policy implications of the polarization between the metropolitan and non-metropolitan areas. In other words, it is found that old companies make a significant contribution to revitalizing the local economy, suggesting that further policies regarding corporate succession are required to support the old companies in the future.

Currently, the main technologies of various fourth industries are big data, the Internet of Things, artificial intelligence, blockchain, mixed reality (MR), and drones. In particular, "digital twin," which has recently become a global technological trend, is a concept of a virtual model that is expressed equally in physical objects and computers. By creating and simulating a Digital twin of software-virtualized assets instead of real physical assets, accurate information about the characteristics of real farming (current state, agricultural productivity, agricultural work scenarios, etc.) can be obtained. This study aims to streamline agricultural work through automatic water management, remote growth forecasting, drone control, and pest forecasting through the operation of an integrated control system by constructing digital twin data on the main production area of the nojinot industry and designing and building a smart farm complex. In addition, it aims to distribute digital environmental control agriculture in Korea that can reduce labor and improve crop productivity by minimizing environmental load through the use of appropriate amounts of fertilizers and pesticides through big data analysis. These open-field agricultural technologies can reduce labor through digital farming and cultivation management, optimize water use and prevent soil pollution in preparation for climate change, and quantitative growth management of open-field crops by securing digital data for the national cultivation environment. It is also a way to directly implement carbon-neutral RED++ activities by improving agricultural productivity. The analysis and prediction of growth status through the acquisition of the acquired high-precision and high-definition image-based crop growth data are very effective in digital farming work management. The Southern Crop Department of the National Institute of Food Science conducted research and development on various types of open-field agricultural smart farms such as underground point and underground drainage. In particular, from this year, commercialization is underway in earnest through the establishment of smart farm facilities and technology distribution for agricultural technology complexes across the country. In this study, we would like to describe the case of establishing the agricultural field that combines digital twin technology and open-field agricultural smart farm technology and future utilization plans.

RFID that provide automatic identification by reading a tag attached to material through radio frequency without direct touch has some specification, such as rapid identification, long distance identification and penetration, so it is being used for distribution, transportation and safety by using the frequency of 125KHz, 134KHz, 13.56MHz, 433.92MHz, 900MHz, and 2.45GHz. Also it is one of main part of Ubiquitous that means connecting to net-work any time and any place they want. RFID is expected to be new growth industry worldwide, so Korean government think it as prospective field and promote research project and exhibition business program to linked with industry effectively. RFID could be used for access control of person and vehicle according to section and for personal certify with password. RFID can provide more confident security than magnetic card, so it could be used to prevent forgery of register card, passport and the others. Active RFID could be used for protecting operation service using it's long distance date transmission by application with positioning system. And RFID's identification and tracking function can provide effective visitor management through visitor's register, personal identification, position check and can control visitor's movement in the secure area without their approval. Also RFID can make possible of the efficient management and prevention of loss of carrying equipments and others. RFID could be applied to copying machine to manager and control it's user, copying quantity and It could provide some function such as observation of copy content, access control of user. RFID tag adhered to small storage device prevent carrying out of item using the position tracking function and control carrying-in and carrying-out of material efficiently. magnetic card and smart card have been doing good job in identification and control of person, but RFID can do above functions. RFID is very useful device but we should consider the prevention of privacy during its application.

In the 21st century, knowledge is an important asset to improve productivity in the business world. In today's rapidly changing business environment, companies have rigorously brought in knowledge management system in order to secure the sustainable competitiveness and effective knowledge management. Knowledge management has now become mandatory, not optional. Today many companies which have built knowledge management on top of information technology and hardware-based infrastructure are having a difficulty in creating organizational culture in knowledge management. Even though companies have invested substantial time and money in knowledge management, the performances have not met their expectations. To solve this problem, software oriented strategy for knowledge management such as education and networking is more needed rather than hardware oriented strategy such as information technology systems. Though the knowledge management framework suggested in this study is exploratory, this study contributes to the clarification of the critical elements that companies which are about to build knowledge management should take in account.

Public policy responses to the digital/information revolution and the micro-economic reforms that it facilitates have inspired exploration of the scope for local government implementation of digital spatial data handling(DSDH) of information relating to, among other things, asset inventory, environmental and utility management, address management, and planning. The results from these explorations are such that few doubt the value of bringing the public policies to practice, but diffusion rate and pattern of the approaches demonstrated by the scoping experiments will reflect institutional/cultural matters, indicators of the relative significance of which might be at least partly predicted from appraisal of case studies. This argument is exemplified by reference to case studies in adoption of DSDH by local government organizations in Korea and in Australia.
