북한군의 호남방면 대우회 기동은 6.25전쟁 기간 동안 북한군이 보여준 가장 빠른 기동이었으며, 국군과 연합군의 낙동강 방어선을 전면 조정하게 할 만큼 위협적인 공격이었다. 하지만 본 연구가 간접접근전략 측면에서 북한군의 호남방면 대우회기동을 분석한 결과, 이 기동에는 실패할 수밖에 없었던 여러 요인이 존재했다. 간접접근전략 수행 측면에 있어서 북한군은 전투력 분산, 작전선 변경의 융통성 부족, 지상군 위주의 기동, 심리적 견제 결여 등 여러 실패 요인을 노정했다. 하지만 북한군은 마지막 '기습'을 준비였는데, 그것은 북한군 6사단을 후속하던 7사단이 재차 우회를 감행하여 통영 방면으로 공격을 시도한 것이었다. 이를 통해 북한군은 낙동강 방어선을 돌파하고, 부산으로 향하고자 했다. 그러나 북한군의 공격은 한국 해군·해병대의 통영상륙작전으로 인해 최종 좌절되었다. 바다를 기동공간으로 한 신속한 기동으로 해군·해병대는 주요 요충지를 먼저 점령했고, 유리한 상황을 조성한 가운데 북한군 7사단의 공격을 막아냈다. 해군·해병대의 통영상륙작전은 북한군의 호남방면 대우회기동을 최종 저지함으로써 낙동강 방어선이 유지되도록 하였다.

A vast amount of labeled data is required for deep neural network training. A typical strategy to improve the performance of a neural network given a training data set is to use data augmentation technique. The goal of this work is to offer a novel image augmentation method for improving object detection accuracy. An object in an image is removed, and a similar object from the training data set is placed in its area. An in-painting algorithm fills the space that is eliminated but not filled by a similar object. Our technique shows at most 2.32 percent improvements on mAP in our testing on a military vehicle dataset using the YOLOv4 object detector.

For the key factors determining victory of combat, many works have been focusing on qualitative analyses in the past. As military training paradigm changes along with technology developments, demands for scientific analysis to prepare future military strength increase regarding military training results, and big data analysis has opened such possibility. We analyze the data from KCTC (Korea Combat Training Center) training to investigate the factors affected victory in offensive operations. In this context, we develop a way to measure the victory and the factors related to it from existing studies and military doctrines. We first identify Independent variables that affect offensive operations through variable selection and propose a mathematical model to explain combat victory by performing multiple regression analysis. We also verify our results with battalion-level live training data as well as previous studies on victory factors in the military doctrines.

In this paper, we have developed an evaluation model of technology green index(TGI) which includes 3 evaluation factors and 13 indicators. Furthermore, as presenting the degree of relative importance among evaluation factors and indicators for all R&D evaluation stages and all green technology areas, and applying the proposed model to 5 defense projects, we have found applicability of the model to evaluation of defense R&D projects. The results of evaluation using this model can be used to monitor the performance of project life cycle and develop R&D investment strategy of green technology using portfolio analysis.

The traditional theories of games are based on an assumption that the payoffs have a single dimension. In reality, any alternative is likely to imply more than one payoff. This paper deals with the game against nature with vector payoffs. The purpose of this paper is to develop methods for finding the practical optimal strategy in the game against nature with vector payoffs. Under the assumption that a prior probability over the stats of nature is given, this paper shows that a practical optimal strategy in this game can be obtained by applying a entropy method in order to assess the payoff weight and by employing the concept of compromise solutions in order to reduce the non-dominated solutions. When subjective payoff weights are unknown as well as known, these methods can be used. A numerical example is given.

The Navy is in the process of developing a sonar-operation strategy to increase the effectiveness of underwater target searching capability. HMS is the basic strategy to detect underwater targets. The advantages of HMS is that, it has a short preparation time to operate and can be always used regardless of sea conditions and weather. However, it is difficult to effectively detect underwater targets due to the interaction between marine environments and sonar-operations. During the research, the effectiveness of the HMS system's underwater target searching capability was analyzed by integrating various search and defense patterns, and environment conditions into the simulation. In the simulation the ship search an evasive target within a set region. The simulation presented results for an effective searching and defense methods of underwater targets. These research results can be used as foundation for advancing and improving the sonar operational tactics.

In this paper, we propose a low-power design strategy to minimize energy-consumption for surveillance and reconnaissance sensor networks. The sensor network consists of many different nodes with various operations such as target detection, packet relay, video monitoring, changing protocols, and etc. Each sensor node consists of sensing, computing, communication, and power components. These components are integrated on a single or multiple boards. Therefore, the power consumption of each component can be different on various operation types. First, we identified the list of components and measured power consumption for them from the first prototype nodes. Next, we focus on which components are the main sources of energy consumption. We propose many energy-efficient approaches to reduce energy consumption for each operation type.

As the size and complexity of software increases, it is important to ensure the quality of software through testing. Many organizations refer to international standards or test process models to improve the quality of software through establishing a systematic test process. However, these standards and process models provide general processes that do not reflect the characteristics of the domain or the organization's test policies and strategies. To establish a test process that reflects the characteristics of the organization, test policies and strategies based on the organization's quality objectives and the organizational and domain characteristics should be reflected. This study proposes specific methods for eliciting activities and information to establish organizational software test policies and strategies that are essential to establishing a test process that reflects the characteristics of the organization and the system.

In Sanyue, the identity of the state and the individual is discussed in terms of the class, ideology, system, moral ethics, tactical strategy, national view, Talent image, etc. and It pursues a historical approach in the world history and an attempt to self-realize in the history of mankind. This literature expresses the strength of military theory and discusses the main core points of the country as a military political and tactical strategy as follows: "Shangyue, zhongyue, and Xiayue. In the Shangyue in Sanyue, it describes how to distinguish the heroes who have been appointed through the ceremony, and it shows the accomplishment of the reason. In zhongyue, we discuss how to distinguish the contingency plan the meaning of change. In Xiayue, we discuss practical thinking of moral ethics and explain the possibility of All the officials and sages angry by considering the safety of the country."
