Informatics curriculum has been revised for informatics principles and concepts to effectively teach. According to the revised curriculum, researches are verifying the educational effects of algorithmic thinking and problem-solving abilities using programming language by applying it to various area. However, researches in programming education considering the level of student are yet incomplete. This research has analyzed the impact of the perceived level of problem solving on the performance of project completeness. As results of difference of project completeness, a high perceived level of problem solving group's performance of project completeness was higher than a low perceived level of problem solving group's one. Analysis of the impact of the perceived level of problem solving on the performance of project completeness, 'problem finding' factor had a significant impact. This research suggested the importance of 'problem finding' and self-reflecting introspective 'reviewing' stages in problem solving process using programming language.abstract of your study in English.

This study developed a program suitable for operating an infinite creative space within the public library, and analyzed the effect of promoting participants' creativity through a trial run of the program. To do this, we operated a "picture book making activities" program in the infinite creative space of J library located in Chungbuk. This program was performed for 18 elementary students in grades 3-6. Torrance TTCT (The Torrance Tests of Creative Thinking) tools were used in this study to measure the overall creativity. As a result, first, awareness of the importance and interest in environmental science was improved through the whole program process. Second, participants' problem-solving abilities improved during the program by having to derive a solution for a given problem through brainstorming. Third, storytelling ability improved after the story-creating elements of the program. Fourth, each participants' creativity was improved through creative activities. Fifth, by publishing the results of creative activities of participants as books, the self-esteem of participating children improved as well.

The Purpose of this study is to explore if people with intellectual disabilities can play a role as 'meaningful informants' in research process in Korea, by challenging the existing paradigm which consists of suspicion on the communication ability of people with intellectual disabilities and truthlessness of their statements, which results in ignorance on the covered life of people with intellectual disabilities. In this research, lessons which could learn through reinterpretation of my research experience are as follows. Firstly, the deficits of communication ability can be supplemented with restructuring interview instruments such as research questions, visual aids etc and adopting conversation analysis methods. Secondly, Suspicion on the truthlessness of their statements can be restructured by epistemological and methodological reinterpretation on the representation of social reality. Thirdly, the mechanism of exclusion and oppression according to the ignorance can be substituted by 'uncovering the life of people with intellectual disabilities', which can be basis of reconstructing the contents of programmes in the disability service centers and disability policies in the government. With these research results it could be argued that there needs to include people with intellectual disabilities as meaningful informants in the research projects funded by the government and also to provide people with intellectual disabilities with diverse roles in the research process by virtue of the development of qualitative research methods in the near future.

This paper proposed embedded application-specific microprocessor(YS-RDSP) whose structure has an additional DSP processor on chip. The YS-RDSP can execute maximum four instructions in parallel. To make program size shorter, 16-bit and 32-bit instruction lengths are supported in YS-RDSP. The YS-RDSP provides programmability. controllability, DSP processing ability, and includes eight-kilobyte on-chip ROM and eight-kilobyte RAM. System controller on the chip gives three power-down modes for low-power operation, and SLEEP instruction changes operation statue of CPU core and peripherals. YS-RDSP processor was implemented with Verilog HDL on top-down methodology, and it was improved and verified by cycle-based simulator written in C-language. The verified model was synthesized with 0.7um, 3.3V CMOS standard cell library, and the layout size was 10.7mm78.4mm which was implemented by using automatic P&R software.

This study develops the real time ULTC(Under Load Tap Changer) control strategy with LDC setting values moved dynamically using artificial neural networks. The suggested strategy can improve the ULTC voltage compensation capability by building 2 types of neural networks, ANNs and ANNg. ANNs recognizes the uncompensated MTr sending voltage change caused by the receiving voltage variation. And ANNg dynamically determines the most appropriate ULTC setting valtage chanbe caused by the receiving voltage variation. And ANNg dynamically determines the most appropriate ULTC setting values by recognizing the voltage level obtained from ANNs, and the section load pattern for each time period. In order to evaluate the suggested approach, the ULTC voltage compensation strategy are simulated on a 8 feeder distribution system. Artificial neural networks developed in this study are implemented in FORTRAN language on PC 386.

In game developments, the design results are often modified not only in the design phase but also in the implementation and test phases. The results of game design are consisted of the results of game rule design and the results of game contend design. The results of game rule design should be correctly understood to all the participants, be efficiently managed by the given configuration controls, and be accurately verified. In this study, we carry out a survey of representation methods of game rules in game design. We have the comparison analysis of the written representation, the UML representation, the Petri net representation, and script-language representation methods about the suitability of the representation method for game rule designs. The comparison analysis is about the representation scope, the visual representation, the automated verification, and the configuration management. The analysis results show that the UML representation is the best method but it needs more convenient automated verification method.

This paper emphasizes the effect of using poetry in the University General English education and suggests the teaching method of English education with a Frost's poem, "Out, Out- ." These days, learner-centered English education and integrative study of four linguistic functions, reading, listening, speaking and writing are considered important in the University General English class. Poetry is very effective text for the education purposes. Poetry techniques like a visual image, rhythm, rhyme, or repetition are actually mnemonics and strongly connected to the enhancement of memory and oral linguistic function. This paper suggests the specific education methods in the poetry selection, pre-reading step, reading step and after- reading step with concrete examples of "Out, Out-." These education methods through the 'oral text' can be a good and sustainable model for learner-centered education.

The future society requires not only knowledge but also various competencies, including creativity, cooperative spirit and integrated thinking. This research develops a program for integrating mathematics and information science to enhance important mathematical competencies such as problem-solving and communication. This program does not require much prior knowledge, can be motivated using everyday language and easy-to-access tools, and is based on creative problem-solving activities with multilateral cooperation. The usefulness and rigor of mathematics are emphasized as the number of participants increases in the activities, and theoretical principles stem from the matrix theory over finite fields. Moreover, the activity highlights a connection with error-correcting codes, an important topic in information science. We expect that the real-world contexts of this program contribute to enhancing mathematical communication competence and providing an opportunity to experience the values of mathematics and that this program to be accessible to teachers since coding is not included.
