Virtual Robot Education System (VRES), which is for programming education with a Lego Mindstorm NXT robot, is designed and implemented. Through this system, program learners can edit source code, compile, download it into the robot, and run their executive program. In order to observe it, the system includes web cameras and provide monitoring services. Thus, students are able to verify the operation of robot into which they download their program in detail and to debug if necessary. In addition, we design a new simple user-friendly programming language and a corresponding compiler for it. With those tools, learner can more easily create programs for NXT robot and test them than Java language. A educator can control and manage the robot for the subject of a class with direct control mode of our system. Therefore, the proposed system is able to support students to learn robot programming during or after regular classes with web browsers through Internet.

IDC는 기업 및 개인 고객에게 전산 설비나 네트워크 설비를 유치하여 유지·보수 등의 서비스를 제공하는 곳으로, 서버 장비 및 통신장비의 운영과 관리를 대행하여 서버의 안정성, 보안성과 서버가 제공하는 서비스의 품질을 유지해 주는 시설이다. 하지만 학교나 일부기업에서는 자신들의 고유 서비스를 위해 호스트를 자신들의 NOC(Network Operation Center)에 놓아두게 되고, 그러면 IDC에서 지원하는 다양한 관리 서비스를 제공받지 못한다. 본 논문에서는 웹 기반 IDC 관리형 인터넷 서비스 모니터링 및 관리시스템의 구조를 제안하고 시스템을 구현한다. 웹에서 효과적인 모니터링 및 관리를 위하여 JAVA 기반의 설계를 하였으며, 인터넷 서비스에 대한 효율적인 관리를 위하여 ICMP 프로콜을 사용하였다. 제안된 시스템을 이용하여 원격지의 서버의 상태나 인터넷 서비스의 전반적인 상태를 일정하게 유지하며, 웹을 기반으로 하여 모니터링 및 관리를 할 수 있다. 중요 기능은 데이터의 주기적인 수집과, 수집된 정보를 데이터 베이스에 저장함으로써 네트워크의 상태 변화에 대한 지속적인 관찰이 가능하다. 또한 시스템에 어떤 문제가 발생하였다고 판단될 경우 효율적이고 신속한 대처가 이루어지도록 하기 위하여 관리자에게 보고서를 제출하게 된다.

With the recent development of manufacturing technology and the diversification of consumer needs, not only the process and quality control of production have become more complicated but also the kinds of information that manufacturing facilities provide the user about process have been diversified. Therefore the importance of big data analysis also has been raised. However, most small and medium enterprises (SMEs) lack the systematic infrastructure of big data management and analysis. In particular, due to the nature of domestic manufacturing companies that rely on foreign manufacturers for most of their manufacturing facilities, the need for their own data analysis and manufacturing support applications is increasing and research has been conducted in Korea. This study proposes integrated analysis platform for process and quality analysis, considering manufacturing big data database (DB) and data characteristics. The platform is implemented in two versions, Web and C/S, to enhance accessibility which perform template based quality analysis and real-time monitoring. The user can upload data from their local PC or DB and run analysis by combining single analysis module in template in a way they want since the platform is not optimized for a particular manufacturing process. Also Java and R are used as the development language for ease of system supplementation. It is expected that the platform will be available at a low price and evolve the ability of quality analysis in SMEs.
