In the fourth industrial revolution age, because of advance in the intelligence information technologies, the various roles of AI have attracted public attention. Starting with Google's Alphago, AI is now no longer a fantasized technology but a real one that can bring ripple effect in entire society. Already, AI has performed well in the medical service, legal service, and the private sector's business decision making. This study conducted an exploratory analysis on the possibilities and issues of AI-driven policy decision making in the public sector. The three research purposes are i) could AI make a policy decision in public sector?; ii) how different is AI-driven policy decision making compared to the existing methods of decision making?; and iii) what issues would be revealed by AI's policy decision making? AI-driven policy decision making is differentiated from the traditional ways of decision making in that the former is represented by rationality based on sufficient amount of information and alternatives, increased transparency and trust, more objective views for policy issues, and faster decision making process. However, there are several controversial issues regarding superiority of AI, ethics, accountability, changes in democracy, substitution of human labor in the public sector, and data usage problems for AI. Since the adoption of AI for policy decision making will be soon realized, it is necessary to take an integrative approach, considering both the positive and adverse effects, to minimize social impact.

Klaus Schwab's discussion on the Fourth Industrial Revolution provides a framework for predicting the direction of legal technology development. Technological convergence, which has emerged as the core concept of the Fourth Industrial Revolution has a significant effect on legal technology. In particular, various new technologies, such as legal chatbots and platforms, are being introduced to enhance efficiency and accessibility in the legal field. However, legal technology is still in its early stage, with institutional improvement needed to vitalize the industry. In this paper, we first specify the concept and classification of legal technology in Chapter 2, followed by trends and limitations in Chapter 3 and ways of vitalizing legal technology in the future in Chapter 4. To invigorate legal technology development, it is necessary to put in place legal regulatory measures that stipulate the active disclosure of legal data, such as precedents, and make free use of such measures. In the law, many issues, such as the safety of artificial intelligence, personal information protection, and ethical standards, will be discussed in the future. Therefore, via this paper, we hope to promote the formation of social consensus and prepare countermeasures, such as legislative measures.

Quality evaluation of beef carcasses is an important issue in the livestock industry. Recently, through the AI monitor system based on artificial intelligence, the quality manager can receive help in making accurate decisions based on the analysis of beef carcass images or result information. This artificial intelligence dataset is an important factor in judging performance. Existing datasets may have different surface orientation or resolution. In this paper, we proposed a two-stage classification model that can efficiently manage the grades of beef carcass image using deep learning. And to overcome the problem of the various conditions of the image, a new dataset of 1,300 images was constructed. The recognition rate of deep network for 5-grade classification using the new dataset was 72.5%. Two-stage evaluation is a method to increase reliability by taking advantage of the large difference between grades 1++, 1+, and grades 1 and 2 and 3. With two experiments using the proposed two stage model, the recognition rates of 73.7% and 77.2% were obtained. As this, The proposed method will be an efficient method if we have a dataset with 100% recognition rate in the first stage.

In a situation where digital transformation using artificial intelligence is active around the world, the growth of domestic AI companies or AI industrial ecosystems is slow. Where a large amount of government funds related to AI are being invested to overcome the difficult economic situation, systematic research on the effect is insufficient. So, this study aimed to examine the policy effectiveness of the government artificial intelligence solution voucher support project for small and medium-sized enterprises (SMEs) using Propensity Score Matching (PSM) and Difference-in-Differences (DID) on the financial performance of beneficiary companies. For empirical analysis, PSM-DID analysis was performed using sales performance since 2019 for 461 companies with a history of voucher support among the AI SMEs data released by the National IT Industry Promotion Agency. As a result of the analysis, the beneficiary companies' asset growth, salary, and R&D expenses increased overall after government support, and no significant contribution could be confirmed in terms of profits. This study suggests that the voucher policy business directly contributed to the company's growth in the short term, but it requires a certain period of time to generate profits.

This paper proposes an artificial intelligence convergence education program for teaching the main concept and principle of Support Vector Machines(SVM) at elementary schools. The developed program, based on Jeju's natural environment theme, explains the decision boundary and margin of SVM by vertical and parallel from 4th grade mathematics curriculum. As a result of applying the developed program to 3rd and 5th graders, most students intuitively inferred the location of the decision boundary. The overall performance accuracy and rate of reasonable inference of 5th graders were higher. However, in the self-evaluation of understanding, the average value was higher in the 3rd grade, contrary to the actual understanding. This was due to the fact that junior learners had a greater tendency to feel satisfaction and achievement. On the other hand, senior learners presented more meaningful post-class questions based on their motivation for further exploration. We would like to find effective ways for artificial intelligence convergence education for elementary school students.

세계화의 빠른 진행과 더불어 외국에 대한 정확한 인식은 매우 중요한 문제로 등장하였다. 아직도 사실적 오류와 더불어 국제관계에서의 위치 때문에 많은 오류가 남아 있는 점도 사실이다. 그 가운데 미국의 위성영상서비스 가운데 가장 대표적인 구글사의 검색서비스와 미국지리정보국의 지명데이터베이스에 관한 내용을 분석함으로서 문제의 뿌리가 어디인지를 밝히고자 하였다. 이미 구글에 관련된 논문은 Science Direct 검색결과 69개가 검색되고 있을 만큼 전세계적 문화적 영향력을 가지고 있다. 본고에서는 전 세계의 지명을 영어로 서비스하고 있는 구글사와 미국의 지명 DB내에 있는 오류사례를 찾아내고, 그 유형을 분석하고, 특히 일제의 강점을 당했던 한국과 대만사례를 비교하는 데 있다. 대만 역시 1945년 제2차 세계대전의 종전으로 인해 일본의 영향에서 벗어나게 되었다. 따라서 지명에도 일본의 영향이 크게 남아 있을 것으로 보고 앞서 나온 유형대로 몇 개의 분석을 실시하였다. 그 중 대표적인 것을 들면, 경상남도 남해군 일원의 위성영상을 보면 최소한 3개의 일본식 지명이 나타난다. 우선 해양지명으로 미조만은 Mijo-wan으로 앵강만은 Oko-wan으로 표시되어 있고, 천황산은 Tenno San이라는 지명으로 나타나고 있다. 제주도의 한라산을 지칭하는 표준어는 Halla-san으로 등재되어 있으나 이명으로 소개되어 있는 것이 무려 11개나 등록되어 있는 것으로 파악되었다. Halla-san에 대한 미국의 NGA(National Geospatial-Intelligence Agency)의 지명정보 데이터베이스에서 검색한 결과는 아래와 같다. 앞의 간라산 또는 간다산 등은 일본식 표기임이 확실하며 여기에 오크랜드산(Auckland, Mount)이라고 또한 표기되어 있음을 확인할 수 있다. 대만의 경우 총 1,280개의 산악명과 산맥명이 등재되어 있으니 일본어 표기는 하나도 없으며, 영어로 Central Mountains와 Seaboard Mountains두개만 영문표기 지명이 등재되어 있을 뿐이며, 그 가운데 12개는 한자로 표기되어 있다. 국내의 지명이 모두 영문 알파벳으로 표기된 것과는 달리 대만의 경우 한자지명이 그대로 데이터베이스에 등재되어 있다. 하천의 경우를 분석해보면 1485개의 지명이 등록되어 있으며 이 가운데 24개는 한자지명으로 표기되어 있다. 유형별 분석을 통한 연구결과가 올바른 지명 찾기에 기여하고, 독도와 백두산에 국한된 지명논쟁의 근간을 공고히 하는데 기여할 것으로 사료된다.

After launching the GOCE (Gravity Field and Steady-State Ocean Circulation Explorer) which obtains high-frequency gravity signal using a gravity gradiometer, many research institutes are concentrating on the development of GGM (Global Geopotential Model) based on GOCE data and evaluating its precision. The precision of some GGMs was also evaluated in Korea. However, some studies dealt with GGMs constructed based on initial GOCE data or others applied a part of GNSS (Global Navigation Satellite System) / Leveling data on UCPs (Unified Control Points) for the precision evaluation. Now, GGMs which have a higher degree than EGM2008 (Earth Gravitational Model 2008) are available and UCPs were fully established at the end of 2019. Thus, EIGEN-6C4 (European Improved Gravity Field of the Earth by New techniques - 6C4), GECO (GOCE and EGM2008 Combined model), XGM2016 (Experimental Gravity Field Model 2016), SGG-UGM-1, XGM2019e_2159 were collected with EGM2008, and their precisions were assessed based on the GNSS/Leveling data on UCPs. Among GGMs, it was found that XGM2019e_2159 showed the minimum difference compared to a total of 5,313 points of GNSS/Leveling data. It is about a 1.5cm and 0.6cm level of improvement compare to EGM2008 and EIGEN-6C4. Especially, the local biases in the northern part of Gyeonggi-do, Jeju island shown in the EGM2008 was removed, so that both mean and standard deviation of the difference of XGM2019e_2159 to the GNSS/Leveling are homogeneous regardless of region (mountainous or plain area). NGA (National Geospatial-Intelligence Agency) is currently in progress in developing EGM2020 and XGM2019e_2159 is the experimentally published model of EGM2020. Therefore, it is expected that the improved GGM will be available shortly so that it is necessary to verify the precision of new GGMs consistently.

This paper is designed to deal with the gaps and differences between the two Koreas, which have gradually increased since the Korean War. The purpose of this study, in particular, is to assess the digital and AI gap between the two parts of the peninsula in the emerging 4^th industrial revolution era that is rapidly innovating the industrial structures, and to present a cooperation plan for the realization of a peace economy and economic prosperity of the Korean Peninsula in the future. In this study, policy alternatives for assessing and bridging the digital gap between South and North were drawn using the comprehensive policy (model) for closing the digital divide, which was one of Korea's past informatization policies. The derived alternatives are meaningful in that they can spark discussions for building the AI-driven society that realizes the integrated economy of the two Koreas complying with the future industrial structure.

The new high order Earth's gravity Model(EGM2008) are expected to improve the application about the Earth's global gravity field. The objectives of this research are to present characteristics on the geoid heights of provinces in South KOREA which calculated from the height anomalies by Earth Gravity Models. For this, seven EGMs (EGM2008<2,190>, EGM2008<360>, EGM96, EIGEN-GL04C, EIGEN-CG03C, EIGEN-GL04S1, and ITG-Grace02S) selected. Geoid heights of fifty BM check points by GPS/levelling are compared with those by NORI-05 model and seven EGMs. And also, geoid heights of 30"$\times$30" grid points in land(sixes blocks ; $1^{\circ}\times1^{\circ}$ sampled) and sea (four blocks ; $1^{\circ}\times1^{\circ}$ sampled) areas of South KOREA by EGM2008 are compared with those by NORI-05 and six EGMs. The results show that geoid heights obtained from EGM2008(2,190) of NGA displayed the nearest results to those by GPS/levelling.

To support the establishment of Information Security Management System, the private sector and the public sector have taken some measures. In the private sector, KISA(Korea Internet & Security Agency) has certified ISMS system based on "The Act on Communication Network Use Promotion and Information Security etc.". In the public sector, No authentication system has been established. Instead, NIS(National Intelligence Service) has enforced 'Information Security Management Condition Evaluation' based on "Electronic Government Act". This article compared ISMS control parts of the private sector with that of the public sector and analyzed the non-enforcement parts of ISMS implementing two sectors for years. Based on this, I would like to consider the method of establishment for efficient ISMS.
