  • For the effective use of satellite communication transponder, tests for the payload system such as IOT(In-Orbit Test), RPM(Routine Payload Monitoring), CSM(Communicatios System Monitoring), and REV(Remote Earth-Station Verification) have to be conducted. Those tests are used in order to verify the condition and generic design of the satellite, to provide a database for operational calculations, and to maintain the quality of communication services. As the satellite communication system gets with wider expansion with higher complexity of operation, tests for the communication system also need more complex operation that usesophisticated computer-controlled measuring system. For and C language based measurement functions, which uses GPIB protocol and SCPI commands. But SICL requires knowledge of BASIC and C language as well as GPIB and SCPL system. This paper introduces a new language called CALSTEP-Control and Access Language for the Systems of Test Equipment and Payload. This language is designed for the operator to perform the tests for the satellite communication system without any special knowledge that is mentioned above. This language has very limited number of commands which are to be used to control the payload system and test equipments to perform IOT and CSM, and those commands are very readable and easy to understand, so an operator without any knowledge of BASIC and C programming language, or SICL and SCPI command can use it.

  • C 언어는 프로그램을 간결하게 구성하기 위하여 많은 연구를 한 언어로, 프로그램 구성 시 오류를 쉽게 발견하기 위한 기능은 부족하지만 다른 고급 언어가 가지고 있는 기술상의 제약이 적어 프로그래밍하기 쉬울 뿐 아니라 다른 프로그래밍 언어의 모태 언어로 평가되어 프로그래밍 언어를 배우려고 하는 사람들의 필수 언어로 여전히 많은 사람들이 공부하고 있다. 그러나 형식 언어가 가지고 있는 여러 가지 특징으로 배우는데 어려워한다. 따라서 본 논문에서는 C 언어를 배우려는 사람들에게 쉽고 재미있고, 정확히 배우도록 하기 위해 C 언어 교육을 위한 교수 학습 지원 시스템 설계를 위한 고찰을 수행하였다. C 언어 교수 학습 지원 시스템을 설계하는데는 학습전이이론과 블랜디드교육, 문제중심학습, 게임을 참고하여 설계하였으며, 다양한 멀티미디어가 사용되게 하였다.

  • The purpose is to produce a model of nuclear reactor trip logic caused by the steam generator water level of Wolsong 2/3/4 unit through an activity chart and a statechart and to produce C language automatically using Statechart-based Formalism and Stalemate MAGNUM toolset suggested by David Harel Formalism. It was worth attempting auto-generation of C language though we manually made Software Requirement Specification(SRS) for safety-critical software using statechart-based formalism. Most of the phases of the software life-cycle except the software requirement specification of an analysis phase were generated automatically by Computer Aided Software Engineering (CASE) tools. It was verified that automatically produced C language has high productivity, portability, and quality through the simulation.

  • This paper describes the design and implementation of the ParaC language that supports parallel programming on the shared memory and distributed memory parallel machine. The ParaC language is designed for the effective use of system resources of scalable parallel systems. The goal is achieved by adding parallel and synchronization constructs for shared address spaces, and remote task constructs for distributed address spaces. This paper also shows the translation method, and we implement the translator and the run-time library for parallel execution of extended constructs.

  • Python language is widely used because of its ease of learning and its wide application range. Arduino, on the other hand, is also widely utilized hardware for physical computing and internet of things(IoT). However, Arduino is controlled by $C{^+^+}$ language, which makes it difficult for non-experts to enter swiftly. This paper proposes an errorless protocol that can simultaneously control multiple Arduino devices in a master device using python language with I2C communication. Using the protocol proposed in this paper, we can take advantage of the python language to control multiple Arduinos.

  • I report on the case of a polyglot ‘savant’ (C), who is mildly autistic, severely apraxic, and of limited intellectual ability; yet who can read, write, speak and understand about twenty languages. I outline his abilities, both verbal and non-verbal, noting the asymmetry between his linguistic ability and his general intellectual inability and, within the former, between his unlimited morphological and lexical prowess as opposed to his limited syntax. I then spell out the implications of these findings for modularity. C's unique profile suggested a further project in which we taught him British Sign Language. I report on this work, paying particular attention to the learning and use of classifiers, and discuss its relevance to the issue of modality: whether the human language faculty is preferentially tied to the oral domain, or is ‘modality-neutral’ as between the spoken and the visual modes.

  • In late years, the tendency to shift the design language of electronic circuits from HDL to C-based languages of C/C)1 and so on is strengthened. The current of adopting these software languages thrives by necessity to solve the problem peculiar to HDL that verification of design is difficult. When we use C-based languages, we can describe the design by higher abstraction degree, mount the design as both hardware and software finally and so that express the design part which is not made clear at early stage the same one language. Therefore, the flexibility of design very improves, the design work in environment the range of applying the whole systems become possible. This paper introduces example at having applied C-based languages in image processing LSI design and describes that the design technique of C-based languages is effective for the system design.

  • Android program is developed with JAVA SDK and executed over virtual machine. For this reason, programming is easier than traditional C language but performance of operating speed decreases. To enhance the performance, NDK development tool, which provides C language, assembly language environment, was proposed. Furthermore, with NEON function provided by ARM, we can utilize the vector operation and enhance performance. In the paper, we explore effectiveness of NDK and then propose advanced multiplication structure with NEON function.

  • In general, flow analysis programs have been built in not JAVA language but such as Fortran, C or C++ because of a merit in performance of computation. However, most developer of those languages are not free for use. User should purchase the development tools of programs, and install it on their own computer. Fortunately, JAVA is a free software, and can be used to develop WEB-based programs. It is well known that the JAVA language is time consuming for calculating. However, the performance of computer power has been increased continuously, so it is sure that the former states can be overcome. In the present study, a flow analysis program, which is interactive with Graphics, using the Web-based programing language, JAVA, has been developed for solving the two-dimensional flow motion.
