  • Naval Combat Management System(a.k.a. CMS) is the core combat power of ROK Navy. CMS which has been localized since 1993 has been developed in various categories. However, in the characteristic of defense industry, CMS software has been rarely developed technically and structurally while the environment of computing system has been developed dramatically. A need for a new paradigm of CMS software development was raised. This paper suggests Naval Shield Component Platform(NSCP) as a standard interface architecture of CMS based on SOLID of OOP which is an advanced programming paradigm and introduce its functionality and feature. We expect NSCP's higher reusability, concurrency and maintainability in CMS software development. As a future work, we are going to apply NSCP to the next CMS software development project and evaluate quantitative, qualitative method.

  • Smart TV is expected to bring cloud services based on virtualization technologies to the home environment with hardware and software support. Although most physical resources can be shared among virtual machines (VMs) using a time sharing approach, allocating the proper amount of memory to VMs is still challenging. In this paper, we propose a novel mechanism to dynamically balance the memory allocation among VMs in virtualized Smart TV systems. In contrast to previous studies, where a virtual machine monitor (VMM) is solely responsible for estimating the working set size, our mechanism is symbiotic. Each VM periodically reports its memory usage pattern to the VMM. The VMM then predicts the future memory demand of each VM and rebalances the memory allocation among the VMs when necessary. Experimental results show that our mechanism improves performance by up to 18.28 times and reduces expensive memory swapping by up to 99.73% with negligible overheads (0.05% on average).

  • In this study, we suggest the selecting evaluation method considering 6 major factors like Compliance system application (Development language conformance, Platform Compliance), threat evaluation (criticality of security incident, possibility of security incident), application benefit (Reliability / quality improvement, Modify Cost) for appropriate secure coding rule selecting evaluation. Using this method, we selected and make a set consist of 197 secure coding rules for Battlefield Management System Software. And calculated the application priority for each rules.

  • 최근 사물인터넷 발달로 의료 IT 분야에서 뜨거운 관심과 많은 연구가 진행되고 있다. 연구 지향적인 성향을 지닌 대형병원이나 대학병원에 비해 중소병원에서는 현 상황에 즉각적으로 적용할 수 있는 실물 플랫폼의 적용이 매우 취약하다. 본 논문에서는 현중소의료에서 활용할 수 있는 환경구축을 중심으로 하여 중소의료기관에서도 적용할 수 있는 의료 IoT(Internet of Thing)를 제안하고자 한다.

  • 반도체 미세화, Glass 대면적화에 따른 산포관리 및 불량방지 필요(공정이격관리), 설비 데이터만으로는 Sensitivity가 낮아 공정 관리 어려움에 따른 대안 필요, 향후 추가 센서에 대한 접목이 용이한 SW Frame 필요, 양산적용을 위한 설비 및 FAB Host의 자동화 연계 개발 필요, 이종데이터의 통합를 통한 최적의 진단 및 관리가 필요합니다(SCM:툴박스). 즉, 기존의 장비 Parameter가 아닌 실제 공정시 Chamber로부터 얻을 수 있는 물리, 전기, 화학적인 데이터를 적합한 이종(異種) 센서를 직접 부착하여 이들 데이터를 통합 관리 분석 및 실시간 Monitoring을 통한 공정 진단 및 실시간 진단을 실행하는 솔루션입니다. 실 공정 시 적용이 유리한 OES 데이터를 주요 인자로 이외의 기타 데이터를 추가로 통합하여 특화된 분석환경과 공정 모니터링을 통하여 TAT (Turn Around Time)를 줄이고, MTBC (Mean Time Between Clean)를 늘림으로써 궁극적으로 칩메이커의 제품의 가격 경쟁력을 확보 할 수 있는 기능이며, 설비사 입장에서는 자사설비의 지능형 시스템을 위한 제반 기술이기도 합니다.

  • 클라우드 사용이 보편화 되고 확대됨에 따라, 서비스를 유연하게 확장 및 축소하여 신속하게 시장의 수요에 대응할 수 있는 PaaS(Platform-as-a-Service) 형태의 서비스가 많은 기업에서 각광받고 있다. 그리고 이러한 PaaS 형 서비스의 핵심이 되는 기술인 컨테이너(Container)와 컨테이너 관리를 효율화 해주는 쿠버네티스(Kubernetes)가 실질적인 표준으로 사용되고 있다. 이때 쿠버네티스 기반의 환경에서 서비스 어플리케이션은 다양한 구성사례가 존재하나, DB 는 아직 안정성 및 데이터 정합성 등을 이유로 베어메탈(Baremetal)이나 VM(Virtual Machine)을 기반으로 구성하고 있는 상황이다. 그러나, 인프라 구성 및 운영에 있어서도 파드(Pod) 형태의 DB 구성은 베어메탈 및 VM 대비 장점이 존재한다고 생각하여 본 실험을 수행하였다. 본 논문에서는 서비스 응답시간 및 자원 사용의 효율성 측면에서 VM 기반의 DB 와 쿠버네티스 파드 기반의 DB 에 각각 트래픽을 발생시켜서 비교한 결과와 시사점을 제시한다.

  • Cardiovascular disease is the leading cause of death in America [1]. This kind of situation leads researcher to find out how to analyze the disease without using a living human heart. Computer simulation is the solution. Based on the existed clinical data and mathematical formulas from the journals, we can simulate a human heart activity using a computer. Moreover, we can also use the existed biological data in our simulation program, such as CellML (Cell Markup Language) [2].

  • In this work, we studied the interactions of the complexes of a DNA base inserted between graphene layers through density functional theory (DFT) calculations. We find that there exists the negligible energy barrier as well as robust and distinguishable electronic fingerprints during the translocation of the DNA bases. Our result shows that the bilayer graphene can be a possible candidate for the future-generation of DNA sequencing device platform.

  • This paper aims to build a drone platform based on an optimum design of its single arm. We assumed its single arm as a cantilevered beam with a tip mass. Based on the numerical optimization theory, we conducted validation and optimization of a new design by comparing the results with the similar ones obtained by ANSYS. Finally, this design is reflected in the control simulation, and the requirement of an optimum structural design considering the resonance situation is demonstrated.
