The LVC(Live, Virtual, Constructive) system of CTC(Combat Training Center) is at the very cutting edge of modeling and simulation technology, which has become widely accepted an enabler for a new military training transformation. In this paper, the architecture of LVC system is proposed for the Korean brigade-level CTC, and high level operational architecture, system architecture, and technical standard architecture are suggested.

In this paper, a standard robot design methodology is suggested and a software architecture for modular robot is introduced. The robot is modularized by several functions, and the module is produced according to a standard proposal. Each module requires standard interface for communicate in distributed environments. Software architecture was developed to support distributed component environment, and application development support tools are developed for user convenience. Many robot softwares are developed in a library form so that, they are being used widely robot application software development. Also a device driver was developed for the mostly used sensor and actuator. It is verified that the modular robot can be applied in various fields through guide, errand and guard scenario.

비즈니스 전략 및 환경이 정적인 환경에서 동적인 환경으로 변화의 필요성이 요구되는 유비쿼터스 환경에 제공되는 서비스가 언제, 어디서나, 쉽게 접근하기 위한 이동성을제공하기 위한 기술로 모바일 서비스의 중요성이 대두되고 있다. 현재 웹 서비스에서 사용하고 있는 요청-응답방식의 모바일 환경에서 일관성을 유지하기 힘들다. 서비스 지향 아키텍처를 기반으로 이동성을 고려한 아키텍처를 정의할 필요가 있다. 따라서 에이전트 컴퓨팅아키택처에 의해 상호운영성이 높은 모바일 에이전트 컴퓨팅을 통하여 모바일 환경에서 사용자의 접근을 용이하게 하고 컴포넌트를 이용한 개발의 효율성을 향상시킬 수 있어야 한다. 본 논문에서는 PDA 서비스를 위해 모바일 에이전트를 이용하여 이를 위한 컴퓨팅 환경을 제공하기 위해서 모바일 에이전트 아키텍처를 정의하고 각 레이어에서 식별된 컴포넌트를 개발하기 위한 프로세스를 제시하고자 한다.

Many researches on intelligent system have been performed and various intelligent algorithms have been developed, which are effective under an assumed specific environment and purpose. But in an real environment, the performance of these algorithms can be largely degraded. In this Paper, we Proposed an Evolvable and Reconfigurable(ERI) Architecture based on intelligent Macro Core(IMC) so that various and new algorithms can be easily added incrementally and construct the reconfigured intelligent system easily. We apply the proposed ERI Architecture to face detection and recognition system to show its usefulness.

In this paper, we propose a base address candidate selection method using the $gp register and page granularity as a way to build a static analysis environment for firmware based on MIPS architecture. As a way to shorten the base address search time, which is a disadvantage of the base address candidate selection method through inductive reasoning in existing studies, this study proposes a method to perform page-level search based on the $gp register in the existing base address candidate selection method as a reference point for search. Then, based on the proposed method, a base address search tool is implemented and a static analysis environment is constructed to prove the validity of the target tool. The results show that the proposed method is faster than the existing candidate selection method through inductive reasoning.

최근 공인인증서가 폐지되고 보다 발급이 간편하고 유효기간이 긴 사설인증서가 부상했다. 더불어 탈중앙화를 핵심 개념으로 하는 블록체인 기반 분산 신원 증명(Decentralized Identity, DID)기술이 대두되고 있다. 서비스 환경의 변화에 따라 사용자 인증 기술도 변화가 요구된다. 더욱이 메타버스라는 새로운 인터넷 환경이 조성되고 있는 바 현재 사용자 인증 기술의 동향을 살펴보고 미래에 사용자 인증이 나아갈 방향성을 제시하는 것은 의미가 있어 보인다. 본 논문에서는 사용자 인증 기술의 개요와 사용자 인증 기술의 변천과정을 시작으로 공개키 기반 구조(Public Key Infrastructure, PKI)와 분산 신원 증명을 중심으로 시장에서의 사용자 인증 기술의 동향을 살펴본다. 나아가 메타버스가 상용화되었을 시기에 사용자 인증 기술이 나아가야할 세가지 방향성(분산화, 플랫폼 초월, 생체 기반 인증 중심)을 제시한다.

MND(Ministry of National Defense) has developed .nm AF(Ministry of National Defense Architecture Framework) to guarantee interoperability among defense information systems. Users can easily and consistently develop architecture products through MND AF. There is necessity for development if CADM(Core Architecture Data Model), which facilitate exchange, integration, and comparison for architecture data, to store architecture data from architecture products and reuse them. We developed CADM from defining entities and relationships that satisfy data requirement of each architecture product from MND AF. After we developed architecture products about MIMS(Military Intelligence Management System), and inserted these architecture data to CADM repository. we verified CADM entities and relationships through query. Through CABM which provides common data model for the whole my architectures, interoperability and integration among defense information systems ran be improved, and integrated defense information resources efficiently can be managed.
