Coding education for elementary school student spreads around the world. Game activity that children like is one of coding education methods. Among these, a board game is a tool where 3~4 children can participate together. This study developed a storytelling-based board game to help elementary school students understand Software education. The board game is composed of board, three types of command cards and dice. This study simultaneously surveyed and interviewed 57 fifth- and sixth-grade students at elementary school after playing the board game 4 times so as to analyze the usefulness of the developed software board game. In the results of study, most of elementary school students would be interested and participated in active. Elementary school students actually got to know algorithm easily through board game activity, and learned basic programming concepts such as sequence, condition, loop, variable and operation.

Since the entering SW-centered society in which people make the best use of SW in order to express their own personal ideas or to solve problems, the significance of SW education has been emphasized. It is generally known that storytelling provides motivational and contextual environments. This study conducted an experimental research to find out how Aesop's fables-applied SW educational program would influence computational thinking. Of these students who had participated in an SW educational camp on every Saturday for a total of 6 weeks, the experimental group learned on basic concepts of Scratch programming as working on Aesop's fables and they were led to diverse SW activities such as stories, games, simulations arts, and others. After that, the study carried out a comparison research in relation to the groups' SW concepts, SW implementation and attitudes toward SW education. The result shows that the experimental group came up with higher levels of SW concepts, implementation and positive attitude toward SW education.

The established childcare facilities, which were established as a result of a policy of the government focusing on enlarging the numerous facilities, caused some qualitative deficits. In the existing situations, they usually practice a single fixed program and concentrate on more static teaching then kinetic with over-crowded childcare teachers. Most of the teachers are being taken into consideration as improperly qualified professionals for the jobs in the field and we can also point out the passive form of service of the parents and the communities. Thus, We are interested in putting the management system for common education of children based on website mutual help through service after realizing a proper design into the real childcare education. This system makes database through PHP web programing method, organizes a common childcare group, forms a special educational program for each group to take the most proper way of teaching, and finalizes the management system for Common education of children based website.

Hilbert's rational ambition to establish consistency in Number theory and mathematics in general was frustrated by the fact that the statement itself claiming consistency is undecidable within its formal system by $G\ddot{o}del's$ second theorem. Hilbert's optimism that a mathematician should not say "Ignorabimus" ("We don't know") in any mathematical problem also collapses, due to the presence of a undecidable statement that is neither provable nor refutable. The failure of his program receives more shock, because his system excludes any ambiguity and is based on only mechanical operations concerning signs and strings of signs. Above all, $G\ddot{o}del's$ theorem demonstrates the limits of formalization. Now, the notion of provability in the dimension of syntax comes to have priority over that of semantic truth in mathematics. In spite of his failure, the notion of algorithm(mechanical processe) made a direct contribution to the emergence of programming languages. Consequently, we believe that his program is failure, but a great one.

This study aims to compare and analyse computer curriculum and textbooks of South Korea and North Korea in order to provide the basis for unifying the Informatics Education. Result of this study follows : First, there isn't any course for Informatics Education in the elementary school but it was requisitely carried 2 hours per week in secondary school in North Korea. But contents of curriculum is much different according to the level of school : genius secondary school, first secondary school, general secondary schol. In especially, Informatics Education had centered in genius secondary school. Second, in comparison of computer textbooks used in South and North Korea, we found that most contents of South Korea textbook was selected equally from all scope whereas those in North Korea were not contained the newest contents(e.g. Internet, Multimedia). But in contrast to South Korea textbook, there was BASIC programing course for improving problem-solving skills in North Korea textbook.

This study compared and analysed computer textbooks of the middle school from South Korea and North Korea for preparing the unification of the Korean Peninsula. According to the result of this study, the contents of South Korea textbook were equally selected from all scopes. By contrast, the contents of North Korea mostly consisted of the basic knowledge of computer, word-processing excluding the newest contents as Internet or Multimedia. But with the BASIC programming and algorithm for enhancement of the creative solving ability, prospective IT brains had been trained in North Korea. Moreover, due to differences of language policy and country that delivered IT technology, significant differences were found between South and North Korea in IT terminology. For preparing IT education after unification of the Korean Peninsula, both efforts of people who work in the fields of IT and school system in South and North Korea should be taken in order to relieve these differences.

The syntax-directed translation using semantic actions is frequently used in construction of compiler for text programming languages. it is very useful for the language designers to develop compiler back-end using a syntax structure of a source programming language. Due to the lack of the integrated representation method for a parse tree node and modeling method of syntax structures, it is very hard to construct compiler using syntax-directed translation in visual languages. In this Paper, we propose a visual language compiler generation method for constructing a visual languages compiler automatically, using syntax-directed translation. Our method uses the Picture Layout Grammar as a underlying grammar formalism. This grammar allows our approach to generate parser efficiently u sing And-Or-Waiting Graph and encapsulating syntax definition as one unit. Unlike other systems, we suggest separating the specification and the generation of semantic actions. Because of this, it provides a very efficient method for modification.

Technology-based convergence education is being emphasized for students in the era of the fourth industrial revolution. In math education, students need to increase their capabilities in the future by having them experience mathematical problems using robots and sensors, a key technology in the era of the fourth industrial revolution. To this end, it is necessary to present educational uses for educational robots in relation to math and curriculum from a 'mathematics education perspective' and analyze its educational use in relation to the mathematics and curriculum, considering the role of mathematics at the base of the process of exploring real-world phenomena and solving problems. Based on the analysis of Van Hiele levels of development in geometry and the LOGO activity level of Olson et al.(1987), this study analyzed and presented the level of LEGO Mindstorm activity, a representative educational Robot capable of collecting and analyzing data and programming in the form of block language, in the first to fourth level.

Broadcast-based data dissemination has become a widely accepted approach of communication in the mobile computing environment. However, with a large set of data items, the expected delay of receiving a desired data increases due to the sequential nature of the broadcast channel. This paper explores the issue of designing proper data allocation on multiple broadcast channels to reduce this wait time, and proposes a new data allocation scheme named near optimal data allocation(NODA). The proposed scheme first partitions all data items in K group based on the theoretical lower-bound of the average expected delay to determine data items which each broadcast channel has to broadcast. Then, NODA further partitions each group of data items in B groups using extended dynamic programming algorithm to broadcast data items allocated on the same broadcast channel in different frequencies. The proposed scheme is capable of minimizing the average expected delay time since it can broadcast data items allocated on the same channel reflecting their popularities.
