컴퓨터의 소형화 추세와 더불어 퍼스널 컴퓨터가 직장과 학교는 물론 일반 가정에까지 널리 보급되기 시작하였다. 아울러 이들 퍼스널 컴퓨터 사용자들에게 편리를 제공하기 위한 응용 소프트웨어에 대한 연구가 활발히 이루어지고 있으며 특히 영어를 모르는 사용자들을 위한 컴퓨터의 한글화 문제가 매우 중요시하게 대두되었다. 더구나 오늘날 대중화되고 보편적인 이용 수단이 된 컴퓨터의 교육이나 프로그래밍 언어의 한글화는 상당히 낙후되었던 것이 사실이다. 이에 본 연구에서는 사무처리에 적합한 코볼 언어와 유사한 한글 코볼언어에 대한 설계를 하였다. 한글 코볼 언어의 설계의 궁극적인 목적은 한글의 음운체계에 맞는 좋은 프로그래밍 언어를 개발해서 프로그래머들이 프로그램 작성에 효율을 갖게 하려는데 있다. 이러한 좋은 프로그래밍 언어를 설계해서 구현하는 작업은 상당히 어려운 작업이므로 본 논문에서는 일차적으로 영문 명령어의 한글화와 조사처리에 대한 방법들을 연구하였다.

The revised 7th education course of information implies that students use variety of information devices to solve the common problems and it also includes the programming education for improving problem-solving abilities. Not only improving problem-solving abilities but also developing thinking skill is expected in programming education. However, traditional programming education is teacher-oriented and focused on language syntax. Accordingly, students have heavy cognitive load and it decrease students' interest of programming. Therefore, in this paper, a instructional method of programming using educational robot is proposed to improve interest of elementary students in concretive operation stage for effectiveness of programming education. Additionally, results of experiments show that proposed robot programming instructional method can be applied in elementary education.

Operation and control system has been installed and tested to use energy storage system(ESS) for frequency regulation at 4MW class of ESS demonstration facility installed at Jeju island, Korea in 2013. Simulation tests were performed by programing language C# for power system of Jeju island to develop control algorithm. Site simulation tests were performed in control system itself without connecting power system and energy storage system. Control algorithm was coded, modified and tested to load to controller and communication system and human-machine interface were developed and tested in the process of simulation tests. After similar results to that of simulation tests by programing language were obtained, power system and energy storage system demonstration facility were connected to control system by communication system. Energy storage system for frequency regulation was tested for actual frequency and simulation frequency. The site tests showed the similar results to that of simulation tests and the control systems is possible to be operated for frequency regulation. Faster response of energy storage system for frequency regulation, less costs and less capacity of energy storage systems which cover for frequency regulation of power plants. It is expected that more studies for time-reduction and time-delay elements can make less capacity of energy storage system cover more role of frequency regulation of power plants.

This paper proposes an design of the OLED(Organic Light Emitting Diodes) driver IC using novel verification method. This method using the HDL(hardware description language) simulator, PLI(Programing Language Interface) and image viewer. The proposed method can be used efficiently to function verification in display driver IC.

The purpose of this study is to find the programming capability for the students majoring in H/W. For implementing this purpose, first, the academic achievements on the C language and C++ language are measured for the graduates-to-be majoring in H/W and S/W. Second, the H/W and S/W curriculum are compared and analyzed to derive the relevant factors to give influence on the academic achievement of the programming. Third, to find the influence of mathematic competence on the academic achievement of the programming, the relevance is analyzed in terms of the regression analyses between mathematics curriculum and programing curriculum. This paper presents the effective teaching method for the improvement of the programming academic achievement in the H/W curriculum.

This paper focuses on analyzing Korean language learning effect through the STEAM class using a robot which is targeted on multicultural elementary school students. For the purpose of it, the degree of difficulty and interest of how students feel has been measured. By using the programing tool of Korean language entering base, they learn the programming commands like as variable, data type, branching statement, loop statement, etc in Korean, the effect of Korean learning has been measured. It has been examined two interviews at the beginning and the end of the second semester to measure the effect of Korean language learning. As a result of this research, It can be realized that multicultural children who have similar linguistic characteristics and cultural sphere understood Korean language easily when they take the Korean language class by utilizing a robot, and the class had an effect on the acquisition of Korean language for multicultural children.

In order to analyze the change of student's logical thinking, in this study, we were develop the educational materials. This educational materials were used in algorithm class through educational programming language Scratch. Algorithms of education materials were selected by analysis of foreign ACM and domestic middle school curriculum. The developed educational materials were applied to 4th grade students of elementary school. In order to analyze the change of student's logical thinking, we were used GALT short version. Total logic and Combinational reasoning, in the experimental group students, were growing significantly.

In database application developments, data coexists in memory and disk spaces. To manipulate the memory data, the general programing languages are used and to manipulate the disk data, SQL is used. In particular, the procedural languages for the memory manipulation are difficult to create and manage than declarative languages such as SQL. Thus, this paper shows that a particular structure of memory data, tree structured, can be manipulated by SQL. Most of all, the model data of the user interfaces can be represented by a tree structure and thus, it can be processed by SQL except non set computations. The non set computations could be done by helper classes. The SQL memory data manipulation is more suited to the database application developments which have few complex computations.

In this paper, we proposed DEVS based programming education model that based on the cognitive information processing theory, not a grammatical programming education, and studied effectiveness analysis using computer thinking patterns. By creating a small range of patterns in the grammar which underlies the programming language and solving various examples through combinations, this paper shows an education method to develop problem-solving skills based on algorithmic thinking. The purpose of this study is to facilitate non-majors learn programming languages and understand patterned program structures when writing programs by patterning of control statements which the most important in learning programming.

In this study we present a new approach for computing the partial atomic charge derived from the wavefunctions of molecules. This charge, which we call the "y_charge", was calculated by taking into account the energy level and orbital populations in each molecular orbital (MO). The charge calculations were performed in the software, which was developed by us, developed using the C# programming language. Partial atomic charges cannot be calculated directly from quantum mechanics. According to a partitioning function, the electron density of constituent molecular atoms depends on the electrostatic attraction field of the nucleus. Taking into account the Boltzmann population of each MO as a function of its energy and temperature we obtain a formula of partial charges.
