A visual concurrent programming environment, called ESTGVP is designed and implemented, which is easy to understand, highly portable, and can represent parallel behaviors. For our purpose, a conventional state transition graph is extended so as to enable both of synchronous and asynchronous parallel operations. We call it extended state transition graph (ESTG). ESTGVP uses the ESTG and texts for programming, and makes it easy programming sequential and parallel behaviors. Also, it is easy to understand the control structure of a program because ESTGVP is a visual programming environment based on the graph. ESTGVP is written in Tel language and thus it is highly portable on various operating systems. It consists of three major components; edition, transformation and execution. If necessary, ESTG can be transformed into C or Tel language, and its execution is based on Tel.

Computers can be used in providing new ways to promote intellectual skills. A computer programming environment can create conditions under which an intellectual mode takes root. Especially problem solving skills can be promoted through programming. To investigate whether and, if so, how computer programming enhances problem solving skills, the nature of programming and problem solving skills are examined. Then, issues on the programming learning context in relation to problem solving are presented.

As international market pressures increase, product life cycles are becoming shorter at same time requirements for productivity and flexibility are becoming higher. Major improvement in robot programming user interface is central to increasing productivity and flexibility for automatic manufacturing environments. New computer technologies have the potential to accomplish this improvement. In this study we have developed a system which proves that interactive computer graphics and geometric modeling have matured to the point where their artful application into an integrated system can rsult in radically new and powerful user interface for robot programming. With the graphic user interface environment the system efficiently utilizes the existing CAD data and gemetric modeling techniques for off-line programming and simulations. Also the system successfully generates robot control programs performing the desired tasks given through off-line programming.

Previously, parallel computing was mainly used in areas requiring high computing performance, but nowadays, multicore CPUs and GPUs have become widespread, and parallel programming advantages can be obtained even in a PC environment. Various parallel programming frameworks using multicore CPUs such as OpenMP and PPL have been announced. Nvidia and AMD have developed parallel programming platforms and APIs for program developers to take advantage of multicore GPUs on their graphics cards. In this paper, we develop digital image transformation programs that runs on each of the major parallel programming frameworks, and measure the execution time. We analyze the characteristics of each framework through the execution time comparison. Also a constant K indicating the ratio of program execution time between different parallel computing environments is presented. Using this, it is possible to predict rough execution time without implementing a parallel program.

MSRDS(Microsoft Robotics Developer Studio) provides the ability to simulate these technologies. SPL(Simple Programming Language) of MSRDS provides many functions for sensor programming to control autonomous robots. Sensor programming in SPL can be implemented in two types of schemes: procedure sensor notification and while-loop schemes. We considered the three programming schemes to control the robot movement after studying the advantages and disadvantages of the sensor notification procedure and the while-loop scheme. We also created simulation environments to evaluate the performance of the three considered schemes when applied to four different mazes. The simulation environment consisted of a maze and a robot with the most powerful sensor, i.e., the LRF(Laser Range Finder) sensor. We measured the required travel time and robot actions (number of turns and number of collisions) needed to escape the maze and compared the performance outcomes of the three considered schemes in the four different mazes.

Traditional programming education lacked consideration of contents, methods and learners. In particular, the importance of programming education has been decreased in school because almost no suitable teaching has been executed for elementary school students. To solve these problems, this study proposed the use of MINDSTORMS that is a programming education tool suitable for elementary school students, and verified its effects on learners' creativity. The results of this study show that the tool is highly effective in improving students' creativity. The objectives of programming education are not only learning programming languages but also improving problem-solving ability, logical thinking and creativity. We must offer environment, in which students can control their own learning activity and solve problems by themselves. In addition, MINDSTORMS can be a very useful and suitable tool for programming education.

As IT technology improves, software is being more and more important. Industry demands higher level of programming ability from university graduates. As a result, programming related courses already take higher possession of electronics department curricula. But even though the environment likewise computer laboratory is improved as much, and professors have tried to enhance the quality of their lectures and educational results, still programming education does not match the demand of our society and industry. In this paper, we introduce the overview of programming education in electronics department, KUT and discuss problems in programming language education especially for the 1st year students, since programming education to the 1st year university students becomes one of the most important part as it deals with fundamentals on programming language and we suggest its improvement directions in regards with students, teaching materials, professors, class size, and class hours.

In distributed office, the pairs can program together using a distributed pair programming system. Many CSCW tools featuring remote screen sharing function have insufficient usability, accessibility to introduce many developers to distributed pair programming. In this paper, we suggest a distributed pair programming system based on IDE, which many developers will accept and use easily. We have do#eloped a user scenario and GUI of the system, making distributed pair programming easier and designed with high extensibility by adapting design patterns and implemented in Java language. Our findings will be of significant help to developers dealing with implementation of distributed pair programming function into some commercial IDE.

Industrial robots have been usually controlled using text-based programming languages provided by each manufacturer with its button-based TP(Teaching Pendent) terminal. Unfortunately, when we consider that people who manipulate TPs in manufacturing sites are mostly unskilled with no background knowledge about computer programming, these text-based programming languages using button-based interaction on manufacturing sites are too difficult for them to learn and use. In order to overcome the weaknesses of the text-based programming language, we propose a visual programming language that can be easily used on gesture-enabled devices. Especially, in our visual programming environment, each command is represented as a block and robots are controlled by stacking those blocks using drag-and-drop gestures, which is easily learnable even by beginners. In this paper, we utilize a widely-spread device, Tablet PC as the gesture-enabled TP. Considering that Tablet PC has limited display space in contrast to PC environments, we designed different kinds of sets of command blocks and conducted user tests. Based on the experiment results, we propose an effective set of command blocks for Tablet PC environment.
