We proposed an unified design methodology and verification platform for giga-scale System on Chip (SoC). According to the growth of VLSI integration, the existing RTL design methodology has a limitation of a production gap because a design complexity increases. A verification methodology need an evolution to overcome a verification gap. The proposed platform includes a high level synthesis, and we develop a power-aware verification platform for low power design and verification automation using it's results. We developed a verification automation and power-aware verification methodology based on control and data flow graph (CDFG) and an abstract level language and RTL. The verification platform includes self-checking and the coverage driven verification methodology. Especially, the number of the random vector decreases minimum 5.75 times with the constrained random vector algorithm which is developed for the power-aware verification. This platform can verify a low power design with a general logic simulator using a power and power cell modeling method. This unified design and verification platform allow automatically to verify, design and synthesis the giga-scale design from the system level to RTL level in the whole design flow.

웹 UI 자동화 테스트 환경 구축하여 운영할 때, 현실적으로 어려움이 있다. 자동화 셋을 구축하는데 초기 투자비용이 많이 들고, 구축한 흐름에도 유지보수 비용이 많이 발생한다. 또한 필요시 바로 실행될 수 있는 자동화 셋을 통합 관리하려면 많은 공수가 투입되어야 한다. 본 논문에서는 웹 UI 자동화 테스트시 발생하는 이런 어려움들을 효과적으로 해결할 수 있는 키워드 기반 웹서비스 UI 테스트 자동화 프레임웍 (kUTAF: Keyword based web service UI Test Automation Framework) 을 소개한다. kUTAF은 웹 구성요소와 사용자 행위를 도메인 지정 언어로 매핑시킨 키워드를 사용해 테스트케이스를 작성하여 자동화 테스트를 수행하고, 작성된 자동화 테스트 셋을 효과적으로 통합 관리하는 프레임웍이다. kUTAF을 적용하면 자동화 셋의 유지보수가 쉬워지고, 커뮤니케이션 비용이 감소하고, 자동화 테스트를 통합 관리하는 부문에서 많은 효과를 볼 수 있다.

Various types of robots are being utilized in the construction industry. Particularly, there is high interest in robots that can be applied to plastering automation, which can ensure consistent work quality. In this paper, we propose a robot platform based on wheels for plastering automation. Through experiments, we measured the surface pressure according to the air pressure of the wheel using the designed robot. As a result, we were able to confirm that the designed robot could perform plastering work on soft mortar with uniformly low pressure per wheel.

홈네트워크는 1980년대 Home Automation에서 출발한 개념으로서 가전기기의 자동 및 원격제어, 가정에 쓰이는 에너지(전기ㆍ가스 등)의 효율적 이용, 각종 방범 등을 목적으로 시작하였다. 그러나 Home Automation은 많은 비용을 수반하였고 가전장비와의 통신에 제한이 있었기 때문에 일반인들 속으로 파고들지는 못하였다. (중략)

Currently, advanced national research network groups are continuously conducting R&D for the requirement to provide SDN/NFV-based network automation and intelligence technology for R&E users. In addition, the requirement for providing large-scale data transmission with the high performance networking facility, compared to general network environments, is gradually increasing in the advanced national research networks. Accordingly, in this paper, we propose an open API-based virtual network provisioning automation platform for large data transmission researched and developed to respond to the networking requirements of the national research network and present the implementation results. The platform includes the KREONET-S VDN system that provides SDN-based network virtualization technology, and the Kubernetes system that provides container-oriented server virtualization technology, and the Globus Online, a high-performance data transmission system. In this paper, the environment configurations, the system implemetation results for the interworking between the heterogeneous systems, and the automated virtual network provisioning implementation results are presented.

A practical application of a supercapacitor energy storage system in a polarization instrument is proposed on the basis of the energy storage requirements of an induced polarization (IP) transmitter for geophysical exploration. We focused on the energy storage system of a supercapacitor, the topology of the power converter, and the system control strategy as key technologies, and we performed theoretical research and experimental tests on the system and developed an experimental platform. The experiments validated the theoretical research on the key technologies of the supercapacitor energy storage system and demonstrated the effectiveness of the innovation. Results showed that the storage system is efficient and satisfies the energy storage needs of the IP transmitter.
