The North Korean military's maneuver toward Honam was the fastest maneuver the North Korean army had demonstrated during the Korean War, and it was a threatening attack that forced the Korean and Allied forces to fully adjust the defenses of the Nakdong River. However, when this study analyzed the North Korean military's maneuver toward Honam in terms of indirect approach strategy, there were a number of factors that inevitably led to its failure. In terms of implementing the indirect approach strategy, the North Korean military cited a number of failure factors, including the dispersion of combat forces, the inflexibility of changing the line of operation, the maneuvering of ground forces, and the lack of psychological distaction. However, the North Koreans were preparing for a final "surprise attack," in which the 7th Division, which was following the North Korean 6th Division, took another diversion and attempted to attack in the direction of Tongyeong. With this, the North Koreans intended to break through the Nakdong River defenses and head for Pusan. However, the North Korean attack was ultimately thwarted by the Korean Navy and Marine Corps' Tongyeong Amphibious Operation. With a swift maneuver using the sea as a maneuvering space, the Navy and Marine Corps occupied key points first, creating an advantageous situation and fending off an attack by the North Korean 7th Division. The Navy and Marine Corps' Tongyeong Amphibious Operation finally thwarted the North Korean military's maneuver toward Honam, thus maintaining the Nakdong River defenses.

The Azerbaijani Armed Forces(AAF) that carried out a drone blitzkrieg for a short time defeated the Armed Forces of Armenia in 2020. As a result, the AAF proved that drones aren't supplementary means, but major ones in combat. Simultaneously, the AAF demonstrated that middle powers can shortly implement the revolution in military affairs(RMA) if the organizational culture for deep change are backed up. Especially, the AAF's RMA is full of suggestions to the Repulic of Korea Army(ROKA) because the ROKA wants to prepare the dronbot combat system for the future. After this, the ROKA is able to visualize how to perform the korean style drone blitzkrieg achieving a intact victory if its comabt system and structure are developed at the same time.

과거 지상군이 기동수단으로 각종 차량을 운용하였듯이, 미래 2000년대의 전장에서는 헬기가 주요 기동수단의 하나로 발전할 것이라는 점도 의심의 여지가 없을 것이다. 이러한 전망에서 우리는 김일성 부자의 군사적 위협에 대처하고 주요 무기체계의 자급이란 목표달성을 위해, 앞서정부가 황무지에서 군용차량 자급을 이룩해낸 70년대의 방위산업 투자를 다시한번재현하여, 2000년대 "공중기동차량" 자급을 이룩할수 있도록 서둘러 정부차원의 항공산업 육성책을 마련해 추진하여야 할것이다

군 통신도 앞으로 상용에서의 이동통신 시스템이나 ATM(Asynchronous Transfer Mode), 위성통신과 같은 첨단 통신방식으로 발전하는 추세에 있으므로 전술제대 단위로 위치보고체계의 통신망을 구성한다면 상호운용성(Interoperability)면에서 중대한 문제점이 발생할 수 있다. 한편 장차전의 양상은 화력전, 입체 고속 기동전으로 가는 추세이며 기갑/기계화부대는 비선형 기동전의 주역으로서 적의 취약점을 포착하는 즉시 민첩한 기동전투력으로 종심공격을 실시하여 적에게 불리한 비선형의 전장을 적극적으로 조성하고 주도권을 행사하는 전술작전 능력을 발휘한다

대한민국 해병대는 현재의 남북 대치상황 뿐만 아니라 통일이후에 전개될 다원적 전략환경하에서도 국가안보의 필수적 역할을 수행하고자 한다. 이는 해병대가 국가의 부름에 즉응할 수 있는 상시 전투준비가 완료된 군으로서, 고강도 전면전으로부터 부여받은 임무를 완벽하게 수행하고 모든 전장에서 반드시 승리하는 다목적 국가전략기동군으로서의 사명을 다하기 위한 것이다

This paper describes an Energy Efficient Timetabling Problem(EETP). In these days, the researches on development of an energy efficient railway systems are highlighted over the world. The departures occurred in an electrical power feeding circuit at the same time are necessary to be reduced as far as possible, to minimize the energy consumption. The paper addresses the operational requirements and facility restrictions to construct a mathematical model for EETP. In addition, it suggests several types of objectives for the model.

The ROK Army is promoting cutting-edge, future-oriented military development such as a mobile, intelligent, and hyper-connected Army TIGER system. The future infantry brigade plans to increase mobility with squad-level tactical vehicles to enable combat in multi-domain operations and to deploy various weapon systems such as surveillance and reconnaissance drones. In addition, it will be developed into an intelligent unit that transmits and receives data collected through the weapon system through a hyper-connected network. Accordingly, the future infantry brigade will transmit and receive more data. However, the Army's tactical information communication system has limitations in operating as a tactical communication system for future units, such as low transmission speed and bandwidth and restrictions on communication support. Therefore, in this paper, the information distribution capability of the future infantry brigade is presented through the offensive operation scenario and M&S.

The Army is making efforts to increase combat power by incorporating technologies related to the Fourth Industrial Revolution into the field of defense. In order to utilize these technologies, it is necessary to develop a military tactical communication system that enables transmission and reception of data between command and control system and weapon systems. Therefore, in this paper, we analyze the tactical communication systems of the other countries, derive the limitations of the tactical communication system currently operating in the military. And, a multi-layered integrated operation structure centered on satellites and plans to provide communication on the move to small units are reviewed. Then, we present the necessity of a large-capacity transmission speed by predicting the amount of data that will be generated from weapon systems of the future, and a plan to efficiently manage the network using intelligent network technology.

capsular polysaccharide(CPS), alpha toxin과 재조합 fibronectin binding protein (FnBP)으로 구성된 유방염 백신을 개발하여 야외효능실험을 수행하였다. 이 subunit 백신은 비유우 23두와 처녀우 20두를 대상으로 10개월동안 각각 수행되었다. 비유우는 매 3주간격으로 2회 백신접종을 하였으며 대조군은 PBS를 상유방림조절 주위에 피하주사하였다. 처녀우를 대상으로 한 실험에서는 분만 8주전부터 시작하여 매 3주간격으로 2회 비유우 백신접종부위와 동일하게 접종하였다. 접종후 비유우에서는 황색포도상구균에 의한 총유선내 감염율이 대조균에 비해 유의성있게 감소하였으며 (p<0.001) 처녀우에서도 총유선내 감염이 백신 접종균(1.6%)이 대조군(11.7%)에 비해 다음 비유기동안 유의성있게 낮았다. (p<0.001). 비유기동안 백신접종한 젖소의 체세포수는 변화가 없었으며 처녀우에서는 추가접종후 백신접종군에서 대조군의 체세포수에 비해 낮았지만 통계학적으로 유의성은 없었다(p>0.05). 본 실험결과 황색포도구균에 대한 유방염 아단위 백신은 비유우와 처녀우에서 체세포수를 증가시키지 않고 총 유선내 감염율을 낮추어주었다. 하지만 본 실험은 1군데의 목장을 대상으로 하였기 때문에 향후 대규모 목장을 대상으로 하는 유방염 백신의 야외효능실험이 심도있게 이루어져야 한다고 생각된다.
