북한에 의한 위협이 증대되고 있는 엄중한 안보 상황에서 우리 군은 첨단기술을 활용한 GOP 과학화 경계시스템의 성능개량 사업을 통해 병력 절감 효과를 추구하고 있다. GOP 과학화 경계시스템이 인구절벽에 따른 병역자원 감소에 대한 효과적인 대안이 되기 위해서는 높은 탐지 및 식별률이 보장되어야 하고, 오탐율을 획기적으로 개선함으로써 병력의 개입이 최소화되어야 한다. 그런데, 현(現) GOP 과학화 경계시스템의 경우 양호한 기상환경에서는 비교적 높은 탐지 및 식별률을 보장하지만, 강우 및 안개 등의 악천후 상황에서의 성능은 다소 부족한 것으로 알려져 있다. 이를 극복할 수 있는 대안으로 악천후 시에도 물체를 탐지할 수 있는 레이더 기반 경계시스템이 하나의 대안으로 제시되고 있는데, 본 논문은 2021년 신속시범획득사업을 통해00사단에서 운용 중인 레이더 기반 AI 과학화 경계시스템의 악천후 상황에서의 효과성을 검증하고 이를 통해 향후 GOP 과학화 경계시스템의 발전 방향을 제시한다.

Voice over Internet Protocol (VoIP) has grown in popularity as a low-cost, flexible alternative to the classic public switched telephone network (PSTN) that offers advanced digital features. However, additional security vulnerabilities are introduced by the VoIP system's flexibility and the convergence of voice and data networks. These additional challenges add to the normal security challenges that a VoIP system's underlying IP data network infrastructure confront. As a result, the VoIP network adds to the complexity of the security assurance task faced by businesses that use this technology. It's time to start documenting the many security risks that a VoIP infrastructure can face, as well as analyzing the difficulties and solutions that could help guide future efforts in research & development. We discuss and investigate the challenges and requirements of VoIP security in this research. Following a thorough examination of security challenges, we concentrate on VoIP system threats, which are critical for present and future VoIP deployments. Then, towards the end of this paper, some future study directions are suggested. This article intends to guide future scholars and provide them with useful guidance.

본 논문은 에이전트 기반 모델링 및 시뮬레이션을 바탕으로 한 한국군 GOP 경계시스템에 관한 연구이다. 에이전트 기반 모델링 및 시뮬레이션 기반 소프트웨어인 MANA를 이용하여 다양한 시나리오를 모델링하고 유전학적 알고리즘을 통해 침투 양상이 변화하는 적에 대해 분석하였다. 우리는 유전학적 알고리즘을 이용하여 침투하는 적의 최적화된 행동에 근사하는 값을 구하기 위해 최적화 모델을 구성하였다. 그 결과는 GOP 경계시스템에서 침투하는 적의 행동에 대한 최적화가 경계시스템의 효과성에 현저한 차이를 가져온다는 점과 침투하는 적의 아군 자산에 대한 회피 정도는 각각의 자산의 중요성을 반영한다는 점에서 두 가지 중요한 통찰력을 제공한다.

본 논문은 에이전트 기반 모델링 및 시뮬레이션 개념과 그 플랫폼인 MANA를 적용한 연구이다. 유전학적 알고리즘을 이용하여 획득한 근사 최적화된 침투하는 적의 행동을 바탕으로 병력, 감시, 통신 시스템들로 이루어진 GOP 경계시스템의 효과를 평가하였다. 경계시스템의 효과 분석을 위해 4가지의 효과척도를 이용하였고, 모델을 구성하는 다수의 경계 자산을 고려하기 위해 NOLH 디자인을 적용하였다. NOLH 디자인을 적용함으로써, 시뮬레이션을 효과적으로 수행할 수 있었다. 이 연구의 결과는 경계시스템을 구성하는 경계자산의 효과적인 구성과 소초에 적정한 병력배치 등을 결정하는데 좋은 자료를 제공할 수 있을 것으로 기대한다.

2001년 9월 11일 테러 이후 초국가적 범죄와 테러리즘의 증가로 인해 국경안보의 중요성이 강조됨에 따라 통합적인 CIQ 역량강화가 요구되고 있다. 미국, 캐나다, 호주는 CIQ를 통합하여 여행자 물품 출입국통제 강화 및 공항만 육로 국경보안에 중점을 둔 국경안보 활동을 강화하고 있다. 미국은 2003년 국토안보부 산하에 관세국경관리청(CBP)을 신설하였다. 캐나다도 2003년 공공안전부 산하에 국경보안청(CBSA)을 창설하였다. 호주도 2015년 이민국경보호부(DIBP) 산하로 관세국경보호청을 통합하고, 국경수비대(ABF)를 신설하였다. 그러나 CIQ 업무별 분산된 국경관리체계를 운영하고 있는 한국은 공항만 육로 국경에서 발생하는 불법 출입국, 테러분자 입국, 밀수입, 마약 총기류 밀거래 등 복합적인 국경위협에 통합적으로 대응하기 어렵다. 이를 해결하기 위해서 유사성이 높은 세관 및 검역 업무부터 순차적으로 통합하고, 중장기적으로 관세청이 출입국관리 업무를 위임받아 CIQ 업무 전체를 통합하는 방안도 검토해볼 수 있다. 또는 미국, 캐나다, 호주의 CIQ 단일책임기관을 한국의 실정에 맞게 벤치마킹하여 새로운 통합국경안보조직을 신설하는 방안도 있다.

The article is devoted to the study of the features of administrative liability for offenses in the informational sphere, the definition of the concept and features. Based on the examples of implementation of instruments of European legislation into the national legal system and examples of national legal practice, the authors have identified the features of informational and legal sanctions aimed at restricting the rights of access of subjects to information, prohibiting them to disseminate certain information, restricting the rights to disseminate certain information, and suspending informational activities. It has been substantiated that the administrative liability for informational offenses as a protective legal institution is created to contribute to the solution of such acute problems of legal support of human and society interests in the new informational dimensions.

Discrete event systems interact with the external environment to decide which action plan is adequate. Some of these interactions are not predictable in the modelling phase and require consequently an adaptation of the system to the metamorphosed behavior of the environment. One of the challenging issues is to guarantee safety behavior when failures tend to derive the system from normal status. In this paper we propose a framework to combine diagnose technique with adaptive control to avoid unsafe sate an maintain the normal behavior as long as possible.
