  • The research of the object-oriented visual programming education is related to investigate the instructional method for computer programming, the process for program development for students, and the suitability analysis and design methodology for program development. In order to develop the educational methodology for the students who have the difficulties to study the computer programming and to enhance the abilities for the development of object-oriented programs, in this paper, we suggest the evaluation metrics to apply and assess for the object-oriented programming education. Also, we introduce the visual programming education methodology and curriculum using Alice programming. The evaluation metrics for the visual programming education suggested in this paper, is accepted when the visual programming languages/tools are used in the programming education to assess and analyze the suitabilities for the programming education for students, so to utilize the analyses for abilities of understanding, abstraction, and program implementation by level.

  • The purpose of multipurpose reservoir operation in flood season is to reduce the peak flood at a control point by utilizing flood control storage or to minimize flood damage by controlling release and release time. Therefore, the most important thing in reservoir operation for flood season is to determine the optimal release and release time. In this study, goal programming is used for the optimal reservoir operation in flood season. The goal programming minimizes a sum of deviation from the target value using linear programming or nonlinear programming to obtain the optimal alternative for the problem with more than two objectives. To analyze the applicability of goal programming, the historical storm data are utilized. The goal programming is applied to the reservoir system operation as well as single reservoir operation. Chungju reservoir is selected for single reservoir operation and Andong and Imha reservoirs are selected for reservoir system operation. The result of goal programming is compared with that of HEC-5. As a result, it was found that goal programming could maintain the reservoir level within flood control level at the end of a flood season and also maintain flood discharge within a design flood at a control point for each time step. The goal programming operation is different from the real operation in the sense that all inflows are assumed to be given in advance. However, flood at a control point can be reduced by calculating the optimal release and optimal release time using suitable constraints and flood forecasting system.

  • The computer programming education is very important to study the related subjects in computer science, and also in the technology education for the students finding employment. In this paper, we develop the assessment metrics to evaluate and apply the textual and visual programming in the computer education. Also, we analyze the validity for the programming languages and tools for the education and getting job of students, and choose the appropriate programming language/tool for programming education. And, we develop the curriculum for programming education, finally apply and analyze in computer education of university. Especially, we compare and analyze the effectiveness for the text based programming language(JAVA) and visual programming language/environment(LabVIEW) in the area of embedded/mobile/Web programming fields which are necessary in the related industry to the recent trend of IT technology.

  • Robot programming often sparks students' interest in programming, but it is not easy for them to program both procedure and reactivity of robot movements that are essential requirements. In this study, we reviewed in detail a new programming language, State-Based Squeak. It allows novice students to implement both procedure and reactivity of robots easily. The effect of this new language on robot programming education was also examined using a group of 28 middle school students. According to the results of analyzing the students' understanding of programming, reading and programming abilities the group that used State-Based Squeak (the experimental group) showed a higher completion ratio than the other (control) group. The significance of this study is that a robot programming language has been developed that addresses the concepts of both procedure and reactivity in such a way that middle school students can more easily learn how to program robots, something that is often difficult to attempt even for professional programmers.

  • This paper deals with the design of teaching learning model for programming language education. Various courses related to programming language education have opened at the university having many academic majors. In the meantime, a variety of programming languages have been developed, many integrated development environments of programming language have also been developed for users to make a program easily. But it is difficult for many novice learners to learn programming language still, likewise it is difficult for many teachers to teach the introduction course of programming language. In this paper, we have designed a teaching learning model based on scholastic achievements and blended learning for programming language education. The teaching learning model designed in this study was applied to a course opened in the second semester of 2011. According to the course evaluation result, the teaching learning model for programming language has shown to be an effective for novice learner.

  • In this paper fuzzy goal programming problems with fuzzy constraints and fuzzy coefficients in both matrix and right hand side of the constraints set are considered. Because of fuzzy coefficients in both members of each constraint ranking methods for fuzzy numbers are considered. An additive model to solve fuzzy goal programming problems is formulated. The diversity of each methods provides a lot of different models of auxiliary linear programming problems from which fuzzy solutions to the fuzzy goal programming problem can be obtained.

  • This paper presents an algorithmic approach used in the development of a task-level off-line programming system for the efficient applicaiton of robot. In the method, robot tasks are graphically described with manipulation functions. By applying robot language these graphic robot tasks are converted into commands for the robot. A programming example demonstrates the potentiality of task-oriented robot programming.

  • This paper shows the application of fuzzy set and nonlinear membership function to linear programming problems in a fuzzy environment. In contrast to typical linear programming problems, the objectives and constraints of the problem in a fuzzy environment are defined imprecisely. This paper describes that fuzzy linear programming models can be formulated using the basic concepts of membership functions and fuzzy sets, and that they can be solved by quadratic programming methods. In a numerical example, a linear programming problem with two constraints and two decision variables is provided to illustrate the solution procedure.

  • The effects of the substrate bias on the performance of programming erasing in p-channel flash memory cell have been investigated. It is found that applying positive substrate bias can improve the programming and erasing speed. This improvements can be explained by Substrate Current Induced Hot Electron Injection. From the results, we can confirm that BTB programming method is better in programming and erasing speed than CHE programming method.

  • A novel programming architecture for antifuse FPGA(Field Programmable Gate Array) is described. This architecture prevents programming transistors from breakdown which occurs due to high voltage across the transistors during antifuse programming. Extra mask and processes can be avoided using this proposed architecture. To reduce the applied voltage across the terminals of programming transistors, different voltage ranges are supplied to vertical and horizontal tracks; between programming voltage Vp and Vp/2 for vertical tracks and between Vp/2 and 0V for horizontal tracks. Therefore, Maximum voltage across the programming transistors is half of the programming voltage and an designated antifuse can be programmed by applying maximum voltage for vertical track and minimum voltage for horizontal track while others are subjected to voltage difference below Vp/2.
