Abstract ▼ AI-Helper

The purpose of this study is to compare research trends in the information and communication technology (ICT) field between North and South Korea and analyze the differences by using data mining. Frequency analysis, clustering, and network analysis were performed using keywords from seven South Korean and two North Korean ICT academic journals published for five years (2015-2019). In the case of South Korea (S. Korea), the frequency of research on image processing and wireless communication was high at 16.7% and 16.3%, respectively. North Korea (N. Korea) had a high frequency of research, in the order of 18.2% for image processing, 16.9% for computer/Internet applications/security, and 16.4% for industrial technology. N. Korea's natural language processing (NLP) sector was 11.9%, far higher than S. Korea's 0.7 percent. Student education is a unique subject that is not clustered in S. Korea. In order to promote exchanges between the two Koreas in the ICT field, the following specific policies are proposed. Joint research will be easily possible in the image processing sector, with the highest research rate in both Koreas. Technical cooperation of medical images is required. If S. Korea's high-quality image source is provided free of charge to N. Korea, research materials can be enriched. In the field of NLP, it calls for proposing exchanges such as holding a Korean language information conference, developing a Korean computer operating system. The field of student education encourages support for remote education contents and management know-how, as well as joint research on student remote evaluation.

성능/효과

1 and Fig. 2, image processing is the subject that occupies the highest percentage of the ICT academic papers of the two Koreas. There are 893 papers (16.
As shown in Fig. 3, it can be confirmed that keywords follow the latest trend every year. New keywords are shown every year.
3, the “unmanned aerial vehicle” (UAV) keyword has been on the upward curve since 2016, and the “vehicle” keyword has also been steadily ranked except for 2019
As shown in Fig. 4, the frequency of co-appearance of the top 20 keywords is also high, and it can be confirmed that they are used in various fields. In particular, it can be seen that the frequency of co-appearance in image processing, IoT, and wireless communication fields is high.
Korea. Based on these research results, specific exchange strategies for each ICT field should be established. In the fields of image processing and computer/Internet application/security, the research activities of the two Koreas are high, so joint inter-Korean research is expected to be possible quickly and actively.
For this policy reason, the world’s best communication infrastructure has been established so far. Due to the revitalization of the communications industry, the research frequency was 874 (16.3%), accounting for the second highest proportion of research (Fig. 1).
Korea has the following characteristics. First, there is a higher tendency for independent research than interdisciplinary convergence research. It can be seen that the Eigenvector centrality is relatively low compared to the top 20 keywords in S.
In the subject of autonomous driving/LBS/ITS, it was confirmed that there were many papers on V2X, monitoring systems using drones, and location recognition and estimation. In Fig.
This subject makes for the fourth highest number of research papers. It consists of computer and Internet applications, 230 papers (48%), security and encryption, 219 papers (46%), and Blockchain, 25 papers (5%). Computer and Internet application papers consist of various topics such as computer hardware and software, data communication, and Internet services.
It has been confirmed that keywords of the neural network, such as “DNN,” “CNN,” “deep learning,” and “machine learning,” are used in all fields of ICT such as image processing, industrial technology, and convergence media, rather than a single field
It is necessary to conduct private business exchanges by confirming the demand for industrial technology. It has been confirmed that there is sufficient demand for the establishment of a remote education system, and educational content exchange is necessary. The wireless communication field needs free infrastructure support after an intergovernmental agreement.
Korea’s ICT were divided into a total of eight fields: image processing, computer/Internet application/security, industrial technology, natural language processing (NLP), neural network/decision-making, wireless communication, student education, and sound signal processing.
Korea’s research in wireless communication is poor and its technological completeness is not high, so N
No potential conflict of interest relevant to this article was reported.
In the fields of image processing and computer/Internet application/security, the research activities of the two Koreas are high, so joint inter-Korean research is expected to be possible quickly and actively. Research in the NLP field makes the most of the advantages of N. Korea’s language policy, so that S.
Korea is active in interdisciplinary convergence research. Second, it can be seen that ICT research in S. Korea is very sensitive to trends.
Second, there was a higher tendency to be influenced by Workers’ Party of N
The “IoT” keyword was clustered together with the “security” and “network” keywords, and it is confirmed that security of the IoT is a major topic in S
The papers clustered on the subject of sound signal processing consist of underwater sound and sound navigation and ranging (SONAR), 142 papers (30%), voice recognition, 56 papers (12%), media sound, 56 papers (12%), architectural sound, 20 papers (4%), ultrasound, 20 papers (4%), and others, 189 papers (39%). “SONAR” has been seen for three consecutive years with 14 to 15 frequency since 2017, and “underwater acoustic communication” is 13 times in 2019 (Fig.
Korea has improved knowledge transfer over time and solidified its nuclear research community. The study confirmed that other areas of nuclear research increased interconnectivity over time.

Korea and the demand for manufacturing development are high. If capital is supported and production facilities are equipped with new models, it is expected to be of great help in improving manufacturing efficiency and revitalizing the industry. If S.
Korea authorities will try to cooperate first and favorably. In addition, it is proposed to provide UHD sports videos that S. Korea has the right to broadcast to N.
Based on these research results, specific exchange strategies for each ICT field should be established. In the fields of image processing and computer/Internet application/security, the research activities of the two Koreas are high, so joint inter-Korean research is expected to be possible quickly and actively. Research in the NLP field makes the most of the advantages of N.
Image processing has a very high research rate in both Koreas and research is actively being conducted. It is expected that joint research will be quickly possible from an equal standpoint in the future. In particular, if medical imaging technology is cooperated in consideration of the poor medical environment in N.
It is expected that private exchanges between the two Koreas in the field of wireless communication will not be easy. There is no possibility that N.
Korea. It may be possible to hold cyber security contests in third countries to evaluate security and encryption skills and to start exchanges by organizing a network of human resources cooperation.
Korea recognizes it as a field that requires investment first. Therefore, it is necessary to first sign an agreement between the governments and promote cooperative projects through incentives such as technology transfer and free support. Specifically, these include installation of 4G infrastructure equipment, maintenance training of wireless network systems, and personnel exchanges.
Computer/Internet application/security research is also expected to be very active as a joint research subject between the two Koreas. This proposes to create a special economic zone for ICT and to build a cloud center that can gather a common database from areas where there is no significant difference in opinion such as language, ancient history, medicine, forests, and fisheries. The database aims at the unique culture of the Korean peninsula.
