The U.N. Security Council's North Korea Sanctions Committee estimated that the amount of North Korea's cyberattacks on virtual asset-related companies from 2017 to 2023 was about 4 trillion won. North Korea's cyberattacks have secured funds through cryptocurrency hacking as it has been restricted from securing foreign currency due to economic sanctions by the international community, and it also shows the form of technology theft against defense companies, and illegal assets are being used to maintain the Kim Jong-un regime and develop nuclear and missile development. When North Korea conducted its sixth nuclear test on September 3, 2017, and declared the completion of its national nuclear armament following the launch of an intercontinental ballistic missile on November 29 of the same year, the U.N. imposed sanctions on North Korea, which are considered the strongest economic sanctions in history. In these difficult economic situations, North Korea tried to overcome the crisis through cyberattacks, but as a result of analyzing the changes through the North's cyber attack cases, the strategic goal from the first period from 2009 to 2016 was to verify and show off North Korea's cyber capabilities through the neutralization of the national network and the takeover of information, and was seen as an intention to create social chaos in South Korea. When foreign currency earnings were limited due to sanctions against North Korea in 2016, the second stage seized virtual currency and secured funds to maintain the Kim Jong-un regime and advance nuclear and missile development. The third stage is a technology hacking of domestic and foreign defense companies, focusing on taking over key technologies to achieve the five strategic weapons tasks proposed by Chairman Kim Jong-un at the 8th Party Congress in 2021. At the national level, security measures for private companies as well as state agencies should be established against North Korea's cyberattacks, and measures for legal systems, technical problems, and budgets related to science are urgently needed. It is also necessary to establish a system and manpower to respond to the ever-developing cyberattacks by focusing on cultivating and securing professional manpower such as white hackers.

Twenty-five chipmunk species occur in the world, of which only the Siberian chipmunk, Tamias sibiricus, inhabits Asia. To investigate mitochondrial cytochrome b sequence variations and population structure of the Siberian chipmunk in northeastern Asia, we examined mitochondrial cytochrome b sequences (1140 bp) from 3 countries. Analyses of 41 individuals from South Korea and 33 individuals from Russia and northeast China resulted in 37 haplotypes and 27 haplotypes, respectively. There were no shared haplotypes between South Korea and Russia - northeast China. Phylogenetic trees and network analysis showed 2 major maternal lineages for haplotypes, referred to as the S and R lineages. Haplotype grouping in each cluster was nearly coincident with its geographic affinity. In particular, 3 distinct groups were found that mostly clustered in the northern, central and southern parts of South Korea. Nucleotide diversity of the S lineage was twice that of lineage R. The divergence between S and R lineages was estimated to be 2.98-0.98 Myr. During the ice age, there may have been at least 2 refuges in South Korea and Russia - northeast China. The sequence variation between the S and R lineages was 11.3% (K2P), which is indicative of specific recognition in rodents. These results suggest that T. sibiricus from South Korea could be considered a separate species. However, additional information, such as details of distribution, nuclear genes data or morphology, is required to strengthen this hypothesis.
Various social and environmental problems have recently emerged due to global climate change. In South Korea, coniferous forests in the highlands are decreasing due to climate change whereas the distribution of subtropical species is gradually increasing. This study aims to respond to changes in the distribution of forest species in South Korea due to climate change. This study predicts changes in future suitable areas for Pinus koraiensis, Cryptomeria japonica, and Chamaecyparis obtusa cultivated as timber species based on climate, topography, and environment. Appearance coordinates were collected only for natural forests in consideration of climate suitability in the National Forest Inventory. Future climate data used the SSP scenario by KMA. Species distribution models were ensembled to predict future suitable habitat areas for the base year(2000-2019), near future(2041-2060), and distant future(2081-2100). In the baseline period, the highly suitable habitat for Pinus koraiensis accounted for approximately 13.87% of the country. However, in the distant future(2081-2100), it decreased to approximately 0.11% under SSP5-8.5. For Cryptomeria japonica, the habitat for the base year was approximately 7.08%. It increased to approximately 18.21% under SSP5-8.5 in the distant future. In the case of Chamaecyparis obtusa, the habitat for the base year was approximately 19.32%. It increased to approximately 90.93% under SSP5-8.5 in the distant future. Pinus koraiensis, which had been planted nationwide, gradually moved north due to climate change with suitable habitats in South Korea decreased significantly. After the near future, Pinus koraiensis was not suitable for the afforestation as timber species in South Korea. Chamaecyparis obtusa can be replaced in most areas. In the case of Cryptomeria japonica, it was assessed that it could replace part of the south and central region.
This article reviewed the status of military force on the DMZ(demilitarized zone) without any confidential problems after literature reviewing on a ceasefire agreement and these powerful military force is judged to be a very serious setback to peaceful reunification of the Korean Peninsula. Also it suggests the ways to reduce inter-korean military force based on the political and economic phenomenon to preparing for an era of reunification of the Korean Peninsula. The easing of tension on the inter-korean military force is an essential element in building infrastructure of peaceful reunification. From now on, both Seoul and Pyongyang might check inter-Korea exchange cooperation Project and reconcile their differences. Primarily, The troops of DMZ would be minimized by Modernization for Military confidence-building. Increasing North-South hotline as possible further, it could contributes to ease of tension in case of emergency. Political and economic plans should be presented that do not arise the military tension simultaneously with ensuring political and economic aspects in the North Korea's regime.

We, Korean, still remember the moment that we got so excited due to the expectation of unification between North and South Korea which turned to be failure when Kim, Il-Sung passed away in 1994. However, the recent close relationship between two Koreas has shown the remarkable improvement, and North Korea seems to be ready to expose itself to the western capitalism. The special economy zone in Sinewuiju is one of the examples showing the gradual change in N. Korea. This political change has made possible the cultural exchanges between two countries, which is similar to the process of German unification. It is absolutely necessary to learn from the previous experience happened during the German unification. We, then, need to realize how the Germany managed the problems aroused by unification Especially, the matter in integrating two different public library systems in East and West Germany is treated as a major concern through the paper. The method Germany applied on integrating two different systems was to dissolve the one in East and let it be absorbed by the one in West even the public library system in East German was known as a well-organized network. Therefore, this paper shows the process of the development of East German public library and harmonization of two different public library systems.

Resource evaluation for environment-friendly regional planning using GIS was implemented in Bonghwa-gun, Gyeongsangbuk-do And new paradigms such as 'green tourism', 'eco-tourism', 'eco-village', were considered and applied into resource indicator system. The weighted evaluation was carried out into pixel units and the scores of every 'myeon' were compared with each others. As a result, the area that has the 'Dak-sil-ma-eul' village in Bonghwa-eup got the highest score. When compared every 'myeon' in mean scores, Bonghwa-eup got the first grade, Socheon-myeon the second grade and Choonyang-myeon the third grade. In a comprehensive view, the areas that got higher scores were the lower flat areas and the 'Dak-sil-ma-eul' village in Bonghwa-eup, north-east areas in Choonyang-myeon, north-west areas and south-east areas in Socheon-myeon. In this study, resource evaluation using indicator system and GIS was implemented, and some problems that appeared in this process were resolved.
Gravity, magnetic and VLF surveys were conducted to investigat the structural stability and hazards associated with the Ubong landfill in Pohang City, which has been built to dump industrial wastes. In 1994, the collapse of a bank happened in the 6th landfill site due to sudden heavy rain, and a large quantity of waste materials flowed out to the nearby landfill sites, factories and roads. We used $10{\times}10m$ resolution DEM data for gravity reductions. The maximum variation of the terrain effect in the survey area is about 0.5 mgal and the terrain effect is large in the vicinity of bank boundary. The Bouguer gravity anomaly map shows the effect due to the variatino of thickness and type of waste materials. The small negative gravity anomaly increases from the 9th site to the 6th site. The small negative gravity anomaly of the 9th site reflects the relatively shallow dumping depth of average 14.5 m in this site and increased density of waste materials by the repeated stabilization process of soil overlaying. The 6th site is located at the center of the former valley and rainfall and groundwater are expected to flow from south-east to north-west. Therefore, considering the previous accident of mixing waste and bank materials at the north-west boundary of the landfill, there may be some environmental problems of leakage of contaminated water and bank stability. The complex inversion technique using Simulated annealing and Marquardt-Levenberg methods was applied to calculate three-dimensional density distribution from gravity data. In the case of 6th site, it is apparent that the landfill had been dumped in four sectors. However, most part of the 9th site and showed that high magnetic industrial wastes were concentrated in the 6th site. The result of magnetic survey showing low magnetic anomalies along the boundaries of two sites is similar to that of gravity data. The VLF data also reveals four divided sectors in the 6th site, and overall anomaly trend indicates the directio of former valley.
The purpose on this study is to grasp the clothing habits and problems of the Chinese-Koreans in Yanbian, China through the fact-finding survey about the clothing habits for the Chinese-Koreans in Yanbian, China who have frequent exchanges with the North Korea and have relatively similar home culture preparing for the unification of North and South Korea, also it is to make the basic data for improving their qualities of life. As for the method of study, it centered on the investigation by the questionnaire on the spot and it referred to the data like domestic and abroad literature, field observation, interview and internet, etc. as a reference. Also it centered on the girl college students and the housewives in Yangil City as an object of research. Accordingly, the result of this study is as follows. The Yanbian is the largest Chinese-Koreans group of people in the China. The economic environment in Yanbian is in the middle of the whole China. With the open-economy of China and the contact with the foreign culture, especially with Korea, the 1960s and 1990s coexist in. The Chinese-Koreans in Yangil spend about 1,425 CNY as clothing expenses averages a year, and the estimated value of holding amount of clothing is about 27 suits. They recognize the clothing made in Korea as high-quality and high-price of high-quality articles. They have high interest in the Korean fashion as the younger generation. They prefer to modern, active, refined and mature atmosphere in the clothing atmosphere, but they still do not reach to the level yet in actual. They generally have strong tendency with the preference of black color or dark color because they have small holding amount. The field materials of fiber did not become high-quality articles because they hold in the level of 1960s in Korea. So, the color level of Chinese-Koreans in Yanbian is still low.
As the post-cold war era and globalization go on, national security problems which were not traditional national security problems such as terrorism, crime, environmental disasters, economic crises, cyber-terrorism, diseases, and energy problems threat humanity and nations and demands changes. Also, with the change, the concept of "big government" has emerged as the role of nation expanded. The modern society sees every country change from small government to big government in order to realize the establishment of welfare state. A comprehensive interpretation of security is needed in order to comprehensive protection of citizens beyond outside invasion such as crime, new disaster, terrorism. In Korea, incidents such as Cheonan-Ham, Yeonpeyong-Do, foot-and-mouth disease, Ddos terrorism, pirates hostages, mad cow disease, AI are happening and the humanitarian support for North Korea and the summit of South and North Korea are at a standstill. Also, National emergency management system, comprehensive emergency management center, countrol tower, national security system, cooperation with citizens, establishment of legal and institutional system are needed. The importance of this research is on the reestablishment of new national security and emergency management system according to the comparison between the national security and counter-terrorism system of Korea and that of the United States which is a leading country in this field. Also, the establishment of national emergency management act is needed as a statute for effective function as currently various laws and administrative organizations are dispersed.

Currently, due to the demographic cliff phenomenon in Republic of Korea, A serious defense vacuum could occur due to the lack of South Korean military's personal strength. As a result, The South Korean military has a possibility to implement the polices the prepare for military provocations and preemptive strikes by the North Korean military while resolving the South Korean defense vacuum caused by the shrinking population. It seems like that the only way for the South Korean military to solve the shortage of personal strength due to the population decline is to reduce the number of Mechanized Units(MU) other than, infantry and automate, and autonomous driving the weapons system of the Mechanized Units(MU). In this paper, we propose the use of the virtual autonomous driving of the self propelled artillery K-9's in self selection of the position and occupation of position and self positioning in the position. At the same time in this paper, the self propelled artillery K-9 model robot is used to simulate and the explain about the operation method, necessity and feasibility in the self propelled artillery K-9. In addition, this paper predicted the problems that would arise if the South Korean military deployed autonomous driving self propelled K-9, in real combat.
