Uncertainty is ubiquitous in target tracking wireless sensor networks due to environmental noise, randomness of target mobility and other factors. Sensing results are always unreliable. This paper considers unreliability as it occurs in wireless sensor networks and its impact on target-tracking accuracy. Firstly, we map intersection pairwise sensors' uncertain boundaries, which divides the monitor area into faces. Each face has a unique signature vector. For each target localization, a sampling vector is built after multiple grouping samplings determine whether the RSS (Received Signal Strength) for a pairwise nodes' is ordinal or flipped. A Fault-Tolerant Target-Tracking (FTTT) strategy is proposed, which transforms the tracking problem into a vector matching process that increases the tracking flexibility and accuracy while reducing the influence of in-the-filed factors. In addition, a heuristic matching algorithm is introduced to reduce the computational complexity. The fault tolerance of FTTT is also discussed. An extension of FTTT is then proposed by quantifying the pairwise uncertainty to further enhance robustness. Results show FTTT is more flexible, more robust and more accurate than parallel approaches.

The advent of the 4th Industrial Revolution is also causing many changes in defense operations. Defense reform and the fourth industrial revolution promoted smart defense innovation, and attempts are being made to incorporate cutting-edge science and technology into various fields such as weapons systems and defense operations. Education and training is one of the areas in which information and intelligence are urgently needed in the spirit of defense operations. Due to the nature of defense education and training, which aims to fight against the enemy, there is no emphasis on psychological training in the field rather than informatization, but in developed countries with various experiences of modern warfare, investment and vitalization of education and training are vital. Through this, efforts are being made to foster soldiers with problem-solving skills in uncertain battlefields. The informatization and intelligence of defense education and training is no longer a matter that can be delayed, and the innovation of education and training using cutting-edge science and technology can be said to be an age-old task to improve the results of education and training in the fourth industrial revolution. The purpose of this is because the application of related technologies is not the goal itself as the 4th Industrial Revolution arrives, but it has been made possible through the rapid advancement of science and technology that has made it difficult to realize education and training, even though it has long been desired. Ultimately, education and training data will be integrated and artificial intelligence-based intelligent learning systems will maximize the performance of education and training, thereby improving the combat readiness.

In this paper, we have proposed a design method for standardization of weapon information exchange between a weapon control computer of guided missile system and a high echelon command and control system. Because the weapon control computer based on diverse combat platforms is operated with several kinds of a high echelon system, it is necessary to provide a standardized design method for weapon information exchange between mutual system. In fact, it is possible to standardize a interface design specification of weapon information message because weapon information message is closely related to standard tactical data link message. It is essential that the interface design specification of weapon information is submitted to that of tactical data link information. It seems that this interface design specification is very useful in development process of the future weapon system.

정보통신기술과 타 산업분야 기술과의 융복합은 전통적인 제조업을 비롯한 의료, 건설 분야뿐 만이 아니라 국방 분야에서도 그 수요가 점점 증대되고 있어 민 군의 공통적인 기술 수요와 요구사항들이 새롭게 대두되고 있다. 미래 전장환경은 점차 네트워크를 근간으로 하는 NCW(Network Centric Warfare)로 전환될 것으로 예측되고 있다. NCW 는 C4I-ISR-PGM 의 사이클로 이루어지는 적의 탐지부터 타격까지를 의미하는 것이다. 이를 위하여는 정보통신 기술이 근간이 되어야 하며, 실제 전장을 모사할 수 있는 사이버 전장환경이 수반되어야 더욱 더 효과적이다. 본 논문에서는 최근에 연구개발이 본격화하고 있는 스마트 국방 IT 기술 개발 현황 및 향후 전망에 대해 제시하고자 한다.

현대의 정보화 사회에서는 정보기술이 기업과 공공기관에 도입되면서 정보기술 전반을 관리해야 한다는 필요성이 대두되었고, 비즈니스 목표와 IT의 연계 필요성이 증대되고 함께 IT투자의 중복을 방지하고 ROI를 추구하는 조직들이 늘어났다. 이에 여러 선진 기업들이 IT 거버넌스라는 개념을 제창하였다. IT 거버넌스는 기업의 비즈니스와 IT에 영향을 미치는 구조적 결정인자들의 구조 및 동적양상을 나타내며, 비즈니스와 IT 관련 사내외 위원회 및 부서, 그리고 그들의 활동범위 및 연관관계를 나타내는 프레임워크, 조직도 및 프로세스 구성으로 표현이 된다. 이러한 외부적인 요인과 맞물려 현재 우리 군의 국방 비전과 목표를 달성하기 위한 국방 IT 거버넌스의 재확립은 필수적인 사항이 되었다. 본 논문에서는 국방 IT 거버넌스의 프레임워크를 구축하기 위한 핵심 추진전략에 대해서 기술하였다. 이러한 주장에 뒷받침하기 위해서 IT 거버넌스의 전반적인 내용을 기술하고 국내 외와 해외의 군 사례를 분석하여 보고 국방 IT 거버넌스의 프레임워크 구축을 위한 핵심 추진전략을 연구하였다.

Cloud computing has become a new paradigm by enabling on-demand provisioning of applications, platforms or computing resources for clients. Workflow scheduling has always been treated as one of the most challenging problems in clouds. Commercial clouds have been widely used in scientific research, such as biology, astronomy and weather forecasting. Certainly, it is very important for a cloud service provider to pursue the profits for the commercial essence of clouds. This is also significantly important for the case of providing services to workflow tasks. In this paper, we address the issues of workflow scheduling in commercial clouds. This work takes the communication into account, which has always been ignored. And then, a topology-based workflow-scheduling algorithm named Resource Auction Algorithm (REAL) is proposed in the objective of getting more profits. The algorithm gives a good performance on searching for the optimum schedule for a sample workflow. Also, we find that there exists a certain resource amount, which gets the most profits to help us get more enthusiasm for further developing the research. Experimental results demonstrate that the analysis of the strategies for most profits is reasonable, and REAL gives a good performance on efficiently getting an optimized scheme with low computing complexity.

To build up the military strength based on information oriented armed forces, the Korean ministry of national defense (MND) promotes the defense CALS (Continuous Acquisition and Life cycle Support) initiative for the reductions of acquisition times, improvements of system qualities, and reductions of costs. These defense CALS activities are the major component of the underlying mid and long term defense digitization program and the ultimate goal of program is to bring a quick victory by providing real-time battlefield intelligence and the economical operations of the military. The concept of defense CALS is to automate the acquisition and disposition of defense systems throughout their life cycle. For implementing defense CALS, the technology for exchange and sharing CALS standard data that is created once and used many times should be considered. In order to develop an efficient CALS information exchange and sharing system, it is required to integrate distributed and heterogeneous data sources and provide systematic search tools for those data. In this study, we developed a content based search engine technology which is essential for the construction of integrated data environments. The developed technology provides the environment of sharing the CALS standard data such as SGML(Standard Generalized Markup Language) and STEP(Standard for The Exchange of Product model data). Utilizing this technology, users can find and access distributed and heterogeneous data sources without knowing its actual location.
