In this paper, we propose an efficient friendly forces location data sharing algorithm in a troops using a low bandwidth radio. The future battlefield is a 'Network Centric Warfare' with a concept of identifying the position and power of the enemy and friendly forces and leading the battlefield to victory through proper links at the time of our need. One of the basic elements in the 'Network Centric Warfare' is to share friendly forces location data. The bandwidth and transmission rates of radio used in battalion are low. Nevertheless, we should share our locations data almost in real time for effective fighting in a war situation. This paper describes the efficient method of friendly forces location data sharing based on low bandwidth radio. In particular, the concept of 'network-centered warfare' is reflected in the troop below the battalion to present an integrated and efficient way to shared location data of friendly forces.

This study is a case study of the Ukrainian military's asymmetric combat performance method. The composition of this study is as follows. First, it presented the background for the outbreak of war in the macroscopic framework of Russia-Ukraine. Second, the Ukraine-Russia war, which broke out in February 2022, presented the justification for the study, that is, the direction of the Ukrainian military's asymmetric combat performance in terms of microscopic aspects of the study, and detailed analysis of precision strikes using commercial drones and advanced sensors. Finally, we covered in-depth the case of Ukrainian troops who attempted to attack Russian tanks using semi-automatic laser homing technology. Therefore, the Korean military organization also suggested the justification for gradually introducing and utilizing the system for the Ukrainian military's asymmetric combat performance method, and related follow-up studies should be actively conducted following this study.

The purpose of this study is to examine the historical consciousness and view of the three religions (Buddhism, Taoism, and Confucianism) of Won Cheon Seok who lived a period of historical transition from the end of the Goryeo Dynasty to the early Joseon Dynasty. Actively speaking for the public in his time and having the same attitude as the Neo-Confucian scholars in the end of Goryeo Dynasty, he kept criticizing the abuse of the power by powerful families who made the people fall into a state of distress and misery. He believed the dispatch of troops to conquer the Yodong region as a great opportunity to boost the valiant spirit of his country; however, the reality was quite opposite to his expectation as Lee Seong Gye had withdrawn the army troops at the Wihwado causing a great risk to his country. He took a very hard line stance against what Lee Seong Gye did. Although he was a Confucian scholar, he did not ignore Buddhism and Taoism and understood that after all the three religions were based on the same principle. His deep understanding of Buddhism and Taoism as well as Confucianism helped him to make sense of Confucianism even further. He was able to sublimate the worldly anguish coming from the Confucian thinking system by indulging himself deeply into the world view of Buddhism and Taoism. In the end, his view on the three religions was based on the idea that they taught the same principle. His view of the three religions with transactional features has a huge implication for the contemporary society in which various values and multiple cultures coexist and have more common grounds.

The Korean military is having difficulty maintaining combat power due to the insufficient troop numbers caused by a demographic cliff and the reduction of the mandatory military service period. Recently, discussions on improving the military training system have increased significantly. This paper proposes an optimization model to establish military training schedules to improve combat power. The oblivion and learning effects on training tasks were quantified through a survey and applied to the model. The objective value, combat power, was calculated based on the total task scores of the unit members and the number of task failures after four weeks. The scenarios were configured by the change in educational conditions and initial scores of some tasks. As a result of scenario experiments, combat power has increased by at least 10% and up to 77%, which is sufficient to maintain combat power considering the change in troops. In addition, the planning of combat skill tasks has a significant impact on combat power. Through this research model, it is expected that military training managers will be able to establish a training schedule that maintains or improves the combat power of troops effectively.

For the past 70 years, an intense rivalry has persisted on the Korean Peninsula, and North Korea's nuclear and missile threats are becoming increasingly imminent. Facing a shortage of military resources, South Korea has pursued a national defense reform, significantly reducing the number of units and troops while focusing on ground forces. However, North Korea's strategic objective of unifying South Korea through surprise attacks, prompt responses, and combined nuclear and missile assaults remains unchanged. The central issue in this context revolves around determining the appropriate size of the Korean military's standing forces. This study employs the concept of net assessment as a novel method to ascertain the optimal size of the Korean military. Threats, strategic objectives, doctrine, and unit rotations are simultaneously considered from the enemy's perspective. In anticipation of security risks on the Korean Peninsula, an acceptable troop size will be proposed using the net assessment approach to calculate the appropriate standing force size.

In Korea ,little attention was paid to chiggers until 1950 so only to reports on four species of chiggers were pulished before Korean War. Since 1950 (beginning of Korean War), a marked progress in the study of chiggers has been made in connection with investigations of Epidemic hemorrhagic fever occurring among the United Nations troops which was suspected as a chigger-borne infectious disease and the first report of tsutsugamushi disease in Korea called natives attention to chiggers as the vector mites of this newly known disease in Korea. This paper is mostly based on specimens of author's collections from 3269 Rodentia Insectivora, 9 Chiroptera, 24 Aves , 35 Amphibia and 3 Reptilia during the time from December 1955 to December 1956 but four species were introduced here from works of others . There are reported here five species of chiggers previously known only out of Korea and a new species also. This new species was collected by author but Lipovsky informed his colleague had collected the same one in Korea and they would publish it as new one in near future. This is the reason of describing the new species without specific name . Of course, this paper is incomplete in view of the geographic distribution, seosonal change and host relation etc, but will serve as a brief summary of the chiggers fauna of Korea up to the present. This species described here are as follows : Gahrliepia brennani var. ventralis Neoschongastia posekanyi Euschongastia kigtajimai Euschongastia miyagawai Euschongastia koreaensis Trombicula nagayoi Trombicula japonica Trombicula pomeranzevi Trombicula mitamurai Trombicula tamiyai Trombicula palpalis Trombicula orientalis Trombicula pallida Trombicula scutellaris Trobmicula miotis Trombicula hiranumai Trombicula sp. Trombicula hiranumai Trombicula sp. Trombicula subintermedius Shunsennia tarsalis . Euschongastia ikaoensis . Trombicula koomori Trombicul subakanushi

South Korea has the defense burdensharing agreement with the United States in reference to the U.S. troops stationed in Korea since 1991, based on Special Measure Agreement(SMA). Due to the growth of Korea's economic power and the U.S. provision of the security environment on Korean penninsula, the U.S. government steadily demanded the rise of contributions to common defense from South Korea and South Korea accepted most of the U.S. requests without proper principles of negotiation concerning the cost sharing. This paper analyzes the systems of the Korea－U.S. cost sharing program through a systems thinking, that yields desirable results with a little effort. The three policy leverages are: 1) the development of negotiation principles; 2) the policy making closely linked with National Defense Reform Basic Plan; 3) the policy making with responsibility burdensharing than cost burdensharing. This paper findings will contribute to the developing the Korea－U.S. cost sharing program by providing policy－makers and policy-practitioners with systematic understanding and insight into the dynamics of the program. Also, this will enable the program to execute more effectively with a concrete formula.

Miniature smart-bullet is a human-carrying guided missile designed to hit a target easily while having a miniature size. Contrary to the normal missiles, miniature smart-bullet is highly expected to enhance the military strength and survival rate of troops by its compact size readily carriable to a single soldier. In this paper, previously developed techniques, activities and patents of miniature smart-bullet, particularly its structural shape and actuators are surveyed. Furthermore, analysis of required techniques to develop a miniature smart-bullet are also discussed for upcoming conceptual design.
