Hangoo Jeon,Young-Gi Min,Kwang-Kyu Seo 보안공학연구지원센터 2016 International Journal of Security and Its Applicat Vol.10 No.2
For the purpose of effectively utilizing & managing ICT resources and reducing costs, various companies are using cloud service as their core technological strategy. In spite of such effort, cloud service security, information protection and performance are being considered as areas that need to be considered when implementing cloud service. In Korea, cloud service certification system is being used to ensure user reliability for cloud service and high-quality cloud services are being certified by considering their quality, security and ongoing service capability. Since current certification system is being utilized focusing on management system, however, it lacks the consideration on technical aspects. Accordingly, this study aims to examine information assurance systems such as ISO 20071 and ISMS to propose a framework for enhancing the cloud service certification system of Korea by focusing on security. The findings of this study are expected to help in increasing the use of cloud service by improving user reliability through the increased utilization of cloud service certification system of Korea.

클라우드 컴퓨팅이 보편화 되면서 지금보다 더 저렴한 가격으로 더 유용한 클라우드 기반의 서비스에 대한 요구가 폭발적으로 증가할 것으로 예상되며, 이에 따라 클라우드 서비스 제공자와 사용자간을 연결하고, 클라우드 서비스에 대한 관리 및 감사 등을 제공하는 클라우드 서비스 브로커(CSB)가 요구되는 시점이다. 본 논문에서는 다수의 이종 클라우드 환경에서 클라우드 자원을 통합 관리하여, 클라우드 서비스 제공자(CSP)와 클라우드 서비스 사용자(CSC) 사이에서 중개 기능을 기반으로 가상시스템의 배치, 제어 및 관리를 지원하는 클라우드 서비스 브로커 시스템의 구성 요소 및 역할 등의 프레임워크를 설명한다.

The KORDI has launched a new project to develop multi-legged subsea robot, named CR200, for precise proximity exploration and precise underwater work in the shallow sea under 200m depth. In Ms project, a six-legged underwater robot is proposed for the both of seabed walking and. underwater working in the high tide and high turbidity environment The proposed robot uses two front legs as manipulators. This paper deals with ike design of robot arm combined with leg for the six-legged subsea robot. First, The kinematics structure and shapes of robot arm combined with leg are established. Second, the specific design is performed such as calculation of torque for joints and selections of motor, reduction gears, sensors, and motor controller. Finally, medianical designs were -performed using 2D and 3D CAD design tools. All of the design process will be presented in this paper
해저 보행 로봇 CR200을 위한 매니퓰레이터 기능을 갖는 다리 개발
강한구(Hangoo Kang),심형원(Hyungwon Shim),전봉환(Bong-Huan Jun),이판묵(Pan-Mook Lee) 제어로봇시스템학회 2013 제어·로봇·시스템학회 논문지 Vol.19 No.8
This paper presents the development of a specialized underwater leg with a manipulator function(convertible-to-arm leg) for the seabed walking robot named CRABSTER200(CR200). The objective functions of the convertible-to-arm leg are to walk on the seabed and to work in underwater for precise seabed exploration and underwater tasks under coastal area with strong tidal current. In order to develop the leg, important design elements including the degree of freedom, dimensions, mass, motion range, joint structure/torque/angular-speed, pressure-resistance, watertight capability and cable protection are considered. The key elements of the convertible-to-arm leg are realized through concept/specific/mechanical design and implementation process with a suitable joint actuator/gear/controller selection procedure. In order to verify the performance of the manufactured convertible-to-arm leg, a 25bar pressure-resistant and watertight test using a high-pressure chamber and a joints operating test with posture control of the CR200 are performed. This paper describes the whole design, realization and verification process for implementation of the underwater convertible-to-arm leg.

This paper presents the numerical results of the contact force and durability with optimized design of lip seal. Using the finite element method based on the Ogden model, the contact force and durability of lip seals were analyzed to illuminate the effect of various shaft interferences and the shape of lip seals. And the optimized design is performed through the Taguchi method. The results show that No.5 model is the best model. And the interference, angle and displacement(d) is important factors.
