Today Geo-Spatial Information System(GSIS) has developed and used more widely, and especially it has been more greatly asked for Land Information System as a part of GSIS. Now it has been planning and monitoring for remaking of cadastral maps by the Ministry of Government Administration and Home Affairs. But this is long term project because of the importance of itself. And then it has been needed to computerize cadastral maps for implementation of relative tasks and services. Cadastral maps have some problems; for example, map join in different scales, different administration boundary and so on. In this study General topology algorithm, Polygonization algorithm and Pseudo-topology algorithm was adapted in computerization of cadastral maps. This is called digital map. The area and shape of parcels do not change. As a result it was found that Polygonization algorithm is the best of 3 algorithm and General topology algorithm is the worst.

This study deals with a certified e-document authority system to securely archive e-documents by a government authorized third party. For this study, I have looked at three cases of certified e-document authority systems and compared then with the similar cases in the USA and Japan. In my conclusion, I suggest four ideas to improve the service of certified e-document authority system. First, the company providing the certified e-document authority system needs to expand to special services. Second, they need to concentrate on subject area of their business. Third, they should provide a consulting service for business archives with business customers. Finally, they can support additional services like document risk management and other digital contents archiving.

Geo-spatial information system covers a wide range of applications and technologies and is of great potential interest to many users in government, industry and science. In many civil engineering problems it is necessary to model a landform in order to be able to removed or to be brought in to make the site ready for the proposed developed. The earthwork volume, could be calculated by the trapezoidal formula, Simpson's 1/3 and 3/8 rules. And slope is defined by a plane tangent to the surface as modelled by the digital terrain model at any given point and comprises two components namely, gradient, the maximum rate of change altitude, and aspect, the compass direction of this maximum rate of change. The thesis is the earthwork volume could be counted, readjustment height, slope and aspect analysis of various derived products can be obtained form geo-spatial informations.

Industrial Revolution is a concept and a development that has fundamentally changed our society and economy. Industry 4.0 focuses on the end-to-end digitization of all physical assets and integration into digital ecosystems with value chain partners. At present, we find ourselves at the beginning of this fourth stage, which is characterized by so-called "Cyber-Physical Systems". These systems are a consequence of the far-reaching integration of production, sustainability and customer-satisfaction forming the basis of intelligent network systems and processes. If South Korea ran toward global ICT with the advent of the Fourth Industrial Revolution, North Korea has adhered to a unique Juche science and technology. ICT in South Korea and North Korea seems very difficult to find common interests. However, as seen in the Internet and intranets, information and communication technology can find similarities in many areas than in general science and technology. There are many differences not only in the level of ICT and science and technology but also in the direction. And IT terminology and all technologies are also different. What are we preparing for the unification of North and South Korea? If we look at the science and technology sector at present, there seems to be no systematic preparation by the government. South Korea and North Korea need to be prepared for science and technology cooperation. First, it is necessary to understand the exact situation of North Korea's science and technology. In this study, we will perform research to establish mid and long term plans for revitalization of ICT cooperation between the two Koreas. In this study, we will determine the extent to which the two Koreas utilize ICT based on available ICT capabilities and technologies. To do this, we conducted research to measure and evaluate the ICT development index of North Korea using ICT international index.

The regulation of the game industry by the Korean government is closely related to the specific regulatory behavior from their parents' generation regarding gaming behavior of their children. This is because there exists a gap in terms of digital culture experience between parents and children. This study examined the differences in how moral values affect the awareness or perceptions of the game users. In the results, the norm conformity was found to have a negative influence on the fondness for game users. Age was also shown to have a negative influence on the fondness for the game users. Based on these findings, we also found the mediating effect of age existed specifically with regard to the relation of norm conformity and the fondness for the game users. The results suggest that the game industry promotion policies of Korea should change their existing targets from focusing on everyone to just the elderly.

It is important to identify the mid and long-term strategic technologies and evaluate technology level for the establishment of national R&D policy to upgrade technology level in Korea. This paper summarizes the result of technology level evaluation for 99 key technologies of 'National Technology Road Map', which consists of 5 visions, of Korea. The technology level, the technological gap between Korea and world-top country, the role of government to upgrade technology level, etc. were investigated by the survey (total 1,067 respondents) and the interview with experts related to key technologies. The average technology level of Korea was $65.1\%$ of that of world-top country and average technological gap was 5.8 years. The technology level of vision I 'Building an Information-Knowledge-Intelligence Society' was $71.6\%$ and highest among 5 visions. The highest technology level among 99 key technologies was $85.6\%$ for 'Digital Broadcasting Technology' and the lowest was $20\%$ for 'weather Control Technology'. The major reasons of technological gap were investigated as the lack of R&D personnel ($23.8\%$), the shortage of R&D funds ($17.8\%$), and the insufficiency of basic research ($15.4\%$), in sequence. The average technology level of USA was evaluated to highest in the world. It was presented that the technological power of China increased rapidly in the expert interview. The result of technology level evaluation would be primary information for various national S&T planning, such as S&T basic plan, S&T foresight, technology road map, etc.

The government has invested much budget for 5years to do the Smart-education and operate digital textbook services since 2011. The private enterprises also decided to focus on constructing Smart learning system by investing much budget. If these systems are constructed nationwide and therefore can access to cyber university by using smart devices, we can reduce the information gap and study online lectures to get a grade whenever, whoever and wherever we want to. However, these convenient systems can cause serious problems like falsifying grades by hacking if security systems are weak. In this paper, we formulated cyber university which is secured in terms of security. For this, we simulated the smart-learning system which strengthened the security, considering code algorithm and encryption technique.
