Mathematical formal justification may be seen as a bridge towards the proof. By requiring the mathematically gifted students to prove the generalized patterned task rather than the implementation of deductive justification, may present challenges for the students. So the research questions are as follow: (1) What are the difficulties the mathematically gifted elementary students may encounter when formal justification were to be shifted into a generalized form from the given patterned challenges? (2) How should the teacher guide the mathematically gifted elementary students' process of transition to formal justification? The conclusions are as follow: (1) In order to implement a formal justification, the recognition of and attitude to justifying took an imperative role. (2) The students will be able to recall previously learned deductive experiment and the procedural steps of that experiment, if the mathematically gifted students possess adequate amount of attitude previously mentioned as the 'mathematical attitude to justify'. In addition, we developed the process of questioning to guide the elementary gifted students to formal justification.

Remanufacturing is a series of industrial process by which retired or non-functional products are restored to a like-new condition. The remanufacturing industry provides much more economical and environmental benefits in view of significant materials and energy savings than existing material recycling way. It also has an effect on the substitute of natural resources, and gives the opportunity of high employment creation due to its highly labor intensive work. This paper thus presents the features of remanufacturing and its various benefits, and current status of domestic and overseas remanufacturing industry including USA, Europe, Japan and China. Furthermore, three major tasks for promoting the remanufacturing industry in Korea have been proposed based on the analysis of remanufacturing activities, technologies and related system in advanced countries.

This is a study about importance of reading comics and discussions highlighted on anthropological perspective as a proper way of education. In introduction, we broght in the issues about failure of the past cartoon education in responding adequately to the flow of current comic book industry, as it has been biased to technical education which resulted in negligence of studies about meaning and function of cartoon. On the other hand, emphasizing the need for cartoon education complemented cultural and academic aspects, we presented reading comics and discussions as an alternative. The challenges we need to pay attention throughout reading comics and discussions have considered in all its aspects specifically like creative process of cartoon, coping with social prejudice against cartoon, study about aesthetic value of cartoon, the role of cartoon in cultural democracy, issue about postcolonialism, multiple popularity and etc.

Program plagiarism is a significant factor to reduce the quality of education in computer programming. In this paper, we propose the technique of identifying similar or identical programs in order to prevent students from reckless copying their programming assignments. Existing approaches for identifying similar programs are mainly based on fingerprints or pattern matching for text documents. Different from those existing approaches, we propose an approach based on the program structur. Using paring progrmas, we first transform programs into XML documents by representing syntactic components in the programs with elements in XML document, then run X-tree Diff+, which is the change detection algorithm for XML documents, and produce an edit script as a change. The decision of similar or identical programs is made on the analysis of edit scripts in terms of program plagiarism. Analysis of edit scripts allows users to understand the process of conversion between two programs so that users can make qualitative judgement considering the characteristics of program assignment and the degree of plagiarism.

In this paper, we propose an improved method of differentiated curriculum in social studies class that can be immediately used in the class. There are two major reasons that differentiated curriculum has not been applied to actual educational programs. One reason is the inefficient progress of differentiated curriculum derived from students' self-study based on individual projects and teacher's excessive investment of time in the development and management of individual researches. The other attribute is the difficulty in distinguishing students' academic level due to the lake of distinct criteria, because students are classified into merely two groups, in-depth group and supplementary class. To cope with these problems, we adopted a cooperative learning to enhance the educational effect of students of the similar level. Experimental results validate that the proposed method is effective in the course of social studies.

In this research, we designed an educational activities of exploring mathematics programs in a course of mathematics education in teacher's college. We divided future mathematics teachers into 8 groups and suggested 8 mathematics programs to them. Each group explored one mathematics program. We asked to future mathematics teachers exploring some cases that use effectively a mathematics program in the teaching of school mathematics. In the process of an exploring, we designed some activities of teaching and learning. We provided opportunities of long-term exploration, group learning, presentations, exercises, reflections to mathematics teachers. As a result, future mathematics teachers acquired basic knowledge on the usage of mathematics programs in school mathematics textbook. In addition, their capabilities that are needed to explore mathematics programs have been enhanced. Also they had learned the teacher's positive attitude through the activities of teaching and learning.

This study explores the way to enhance research performance focusing basic and fundamental technology when researchers conduct international joint research with counterparts in foreign countries, funded under the National R&D programs. In order to retain validity and objectivity, mixed approaches including qualitative and quantitative are adapted at the first step. Through this step, main factors affecting the research performance can be addressed, such as the number of SCI papers published, conference attendance held both in domestic and foreign countries, researchers holding PhD involving in projects. Then, at the second step, DEA methodology is applied to explore the way to enhance research performance, based on the analysis at first step. The result at second step shows that the various ways can be drawn according to programs respectively and the general assumption of research funds and number of projects affecting positive outcome is not absolutely mentioned. Therefore, this study implies that input variables including research funds are not compatible with research performance in terms of international joint research and suggests further that the decisive outcome and management be reconsidered according to the programs respectively under the national R&D program.

This paper will address why records management innovation needs to be considered and sought again in 2017 when Korea's new government was inaugurated, and it suggests the direction and strategies of the innovation. Now is time to inherit the innovative spirit of Roh's Participatory Government based on new methods and contents with immanent criticism. This paper proposes the innovation for the "records management by everyone," where everyone involved needs to participate in and proceed with the innovation for the sake of democracy. Not just government offices but also corporations and even ordinary people need to participate in the process of records management and share the results. Records management is necessary and required in places where democracy is practiced, where historical events occur, and where technologies are continuously innovated around the world. This paper proposes 12 strategies and 35 tasks in 6 sectors where records management is required at present. In addition, it also suggests a methodological innovation for using the latest technologies, communicating with every entity, and governing decision-making.

Building and researching high definition maps that support autonomous vehicles, one of Korea's key challenges for the future, are being actively propelled in both private and government sectors with the goal of fast commercialization. Under this perspective, update methods that secure up-to-date information are emerging as key tasks. To provide a plan for establishing efficient renewal systems for high definition maps, we analyzed the present condition of road types, causes of road changes and its annual change rates, and examined where and how such road change information is managed. Furthermore, the method of collection and detection of road change information and the renewal system of high definition maps are defined based on the current study. At the end of the paper, a step-by-step renewal system is proposed through the examination of renewal cycles, contents, and region of high definition maps.

URI spotting (탐지) 문제는 텍스트에 있는 단어열 중에서 URI로 대표되는 개체(entity)에 해당되는 것을 탐지하는 것이다. 이 문제는 두 개의 작은 문제를 순차적으로 해결하는 과제이다. 즉, 첫째는 어느 단어열이 URI에 해당하는 개체인가를 인식하는 것이고, 둘째는 개체 중의성 해소 문제로서 파악된 개체가 복수의 URI에 해당할 수 있는 의미적 모호성이 있을 때 그 URI중 하나를 선택하여 모호성을 해소하는 것이다. 이 논문은 디비피디아 URI를 대상으로 한다. URI 탐지 문제는 개체명 인식 문제와 비슷하나, URI(예를 들어 디비피디아 URI, 즉 Wikipedia 등재어)에 매핑될 수 있는 개체로 한정되므로 일반적인 개체명 인식 문제에서 단어열의 품사열이 기계학습의 자질로 들어가는 방법론과는 다른 자질을 사용할 수 있다. 이 논문에서는 한국어 텍스트를 대상으로 한국어 디비피디아 URI 탐지문제로서 SVM을 이용한 개체경계 인식 방법을 제시하여, 일반적 개체명 인식에서 나타나는 품사태거의 오류파급효과를 없애고자 한다. 또한 개체중의성 해소 문제는 의미모호성이 주변 문장들의 토픽에 따라 달라지므로, LDA를 활용하며 이를 영어 디비피디아 URI탐지에서 쓰인 방법들과 비교한다.
