Electronic educational environments in the conditions of quarantine restrictions of COVID-19 have become a common phenomenon for the organization of distance educational activities. Under the conditions of Russian aggression, Ukrainian proof of their use is unique. The purpose of the article is to analyze the role of electronic educational environments in the process of training applicants for higher education in Ukraine in the realities of a large-scale war. General scientific methods (analysis, synthesis, deduction, and induction) and special pedagogical prognostic methods, modeling, and SWOT analysis methods were used. In the results, the general properties of the Internet educational platforms common in Ukraine, the peculiarities of using the Moodle and Prometheus platforms, and an approximate model of the electronic learning environment were discussed. The reasons for the popularity of Moodle among Ukrainian universities are analyzed, but vulnerable elements related to security are emphasized. It was also determined that the high cost of Prometheus software and less functionality made this learning environment less relevant. The conclusions state that the military actions drew the attention of universities in Ukraine to the formation of their own educational platforms. This is especially relevant for technical and military institutions of higher education.

We can not respond asymmetric warfare effectively. The asymmetric operation is performed in asymmetric methods and means with different characteristics and functions to their enemy. And the character of the asymmetric operation have 'heterogeneity' and 'superiority' in principle. The type of asymmetric strategy is complex and diverse. Since we can classify the type of the asymmetric strategy in many different way and we must study in many ways and aspects. When we study asymmetric war previous cases from modern to ancient era, we can find that the key factors of the victory have superiority of the asymmetric strategy and discriminatory measures. The asymmetry is created when one party has to adapt to the strategic environment. If we want to secure a strategic advantage, we must take a number of case studies and countermeasures for asymmetric warfare.

As science and technology develops, it is expected that more precise and various weapons will be used in a much more complicate future battlefield environment. C4I is a system that provides the proper and necessary information to commanders and their staffs to recognize the battlefield situation by connecting and visualizing the complex battlefield environment and various weapon systems together. Commanders and staffs perform battle command training based on a computer or paper map to better utilize the C4I system and Command Post eXercise(CPX) is a process of the training. This is the way for them to improve command control and decision making skills. Analyzing of line of sight(LOS), identifying communication fringe area, deploying troop strength, and determining unit maneuver are highly restricted under the 2D based CPX. In recent years, however, three-dimensional (3D) CPX simulators have been developed to overcome these drawbacks. In response to this trend, this paper proposes a multi-user based CPX simulator using augmented reality (AR) glass, which can be used as a practical war game simulator.

Global food prices have skyrocketed due to international uncertainties such as COVID-19 and the Russian-Ukrainian War. In this context, the importance of rural areas as a source of food production is also rapidly increasing. However, the issue of regional extinction is emerging as Korea faces the world's lowest fertility rate and fastest aging population. Also, rural areas are losing their population more rapidly than large cities. Therefore, this study aims to analyze the factors that can encourage the influx of fishermen to prevent the disappearance of these fishing villages. As a result of the analysis, in order to prevent the disappearance of fishing villages, among the infrastructure, natural environment, and residential environment variables, the ratio of aged housing related to quality of life, culture and amenities coefficients were found to have a greater impact than other variables. Based on these results, it is judged that it is necessary to establish a sufficient level of infrastructure in fishing villages and to prioritize policies for improving the residential environment.

The ocean provides with not only the global environment and ecology, which is essential for human beings survival, but also various resources for human beings prosperity. The ocean security is to secure and keep the benefits that the ocean provides with to human beings. It is essential to keep enforcement measures for the ocean security. Major marine countries are challenging to secure ocean environment and resources since UNCLOS. The utmost policy priority should be given to the ocean security in Korea.

The boundaries of ROK maritime jurisdictional area remains unclear as two Koreas failed to draw clear maritime boundaries at the armistice agreement and there are no clear maritime boundaries with China and Japan. After the Korean War, the United Nations Command established the northern limit line(NLL) as well as the area of operations(AO) to enforce the DPRK's compliance with the armistice agreement and has been controlling all of the maritime and air activities in the region. ROK also has been controlling the passage of DPRK vessels in the area. Within the AO, third nation vessels have freedom of navigation, Yet, due to the division followed by the Korean War, ROK classifies DPRK as a hostile state and unique controling system is applied to DPRK vessels. Since the establishment of the AO, many changes have been occurring such as adoption of the UN Convention on the Law of the Sea(UNCLOS) and two Koreas' joining the UN. Also, there are continuous inter-Korean conflicts. Therefore, the geographical span of the AO needs to be reconsidered. Furthermore, a legal measure which ensures ROKN vessel's functional capability of controling DPRK vessels must be introduced. This thesis examines post-Korean War DPRK vessel control system in the Korean peninsula as well as how it should be improved.

A method of constructing a war simulation based on Bayesian Inference was proposed as a method of constructing heterogeneous historical war data obtained with a time difference into a single model. A method of applying a linear regression model can be considered as a method of predicting future battles by analyzing historical war results. However it is not appropriate for two heterogeneous types of historical data that reflect changes in the battlefield environment due to different times to be suitable as a single linear regression model and violation of the model's assumptions. To resolve these problems a Bayesian inference method was proposed to obtain a post-distribution by assuming the data from the previous era as a non-informative prior distribution and to infer the final posterior distribution by using it as a prior distribution to analyze the data obtained from the next era. Another advantage of the Bayesian inference method is that the results sampled by the Markov Chain Monte Carlo method can be used to infer posterior distribution or posterior predictive distribution reflecting uncertainty. In this way, it has the advantage of not only being able to utilize a variety of information rather than analyzing it with a classical linear regression model, but also continuing to update the model by reflecting additional data obtained in the future.

Owing to the development of science technology, particularly the smart concept and defense policy factors of the 4th industry, military weapon systems are advanced, and the scientific and operational force is reduced dramatically. The aspect of the future war is characterized by the operation of troops with reduced forces from advanced and scientific weapon systems in an operational area that has expanded more than four times compared to the present. Reflecting on these situational factors, it is necessary to improve combat methods based on the changes in the battlefield environment and advanced weapon systems. In this study, to find a more efficient future combat method in a changing war pattern, this study applied the battle experiment methodology using Vision21 war game model, which is an analytical model used by the army. Finally, this study aimed to verify the future combat method and unit structure. Therefore, the scenario composition and experiment method that reflect the change in the ground operational environment and weapon system was first composed. Subsequently, an analysis method based on the combat effectiveness was applied to verify the effective combat performance method and unit structure of future infantry units.

Thanks to the fact that the 1953 Korea Armistice Agreement does not have any clear provisions on the sea demarcation line, the North Korea insists that the sea demarcation line in the Yellow Sea Area should not be the NLL designated by the Commander in Chief. UN Command, unilaterally, but the hypothetical extention of the Latitude Parallel from the end of the provincial boundary line between Whanghae-do and Kyongki-do In those unique situations at the end of the Korean War, the cease-fire line on the part of the western sea area, a logically indispensable element of the contents of an armistice agreement, however has formed and crystallized by the act of the UN Command designating the NLL. In implementing the South-North Korean Basic Relations Agreement, a fair and clear common consent on the sea demarcation line in the western sea area should be deliberated.
