Sophisticated geometric structure analysis must be preceded to create electronic document from logical components extracted from document image. this paper presents a knowledge-based method for sophisticated geometric structure analysis of technical journal pages. The proposed knowledge base encodes geometric characteristics that are not only common in technical journals but also publication-specific in the form rules. The method takes the hybrid of top-down and bottom-up techniques and consists of two phases: region segmentation and identification. Generally, the result of segmentation process does not have a one-to-one matching with composite layout components. Therefore, the proposed method identifies non-text objects such as image, drawing and table, as well as text objects such as text line and equation by splitting or grouping segmented regions into composite layout components. Experimental results with 372 images scanned from the IEEE Transactions on Pattern Analysis and Machine Intelligence show that the proposed method has performed geometrical structure analysis successfully on more than 99% of the test images, resulting in sophisticated performance compared with previous works.

Only requiring research reports or publishing articles as the final obligation of R&D activities is not sufficient to utilize and reproduce the knowledge information. Since a lot of important data have been ignored and missed by the public or private research institutions, it is not easy to manage and utilize R&D outcomes and to develope knowledge-intensive business as we expect. It is important and rather urgent matter that we should reexamine the related regulations/ laws of Intellectual Property and observe the practical problems of data utilization in real settings. This study reviewed recent studies about domestic R&D institutions, current regulations related IP, and some conflicts with the copyright, and then summarized the problems/ solutions of utilizing R&D information as knowledge assets.

The purpose of this study is to uncover weaknesses in the constructivism in mathematics education and to search for ways to complement these deficiencies. We contemplate the relationship between the capability of construction and the performance of it, with the view of the 'Twofold-Structure of Mind.' From this, it is claimed that the construction of mathematical knowledge should be to experience and reveal the upper layer of Mind, the Reality. Based on the examination on the conflict and relation between the structuralism and the constructivism, with reference to the 'theory of principle' and the 'theory of material force' in Neo-Confucianist theory, it is asserted that the construction of mathematical knowledge must be the construction of the structure of mathematical knowledge. To comprehend the processes involved in the construction of the structure of mathematical knowledge, the epistemology of Michael Polanyi is studied. And also, the theory of mathematization, the historico-genetic principle, and the theory on the levels of mathematical thinking are reinterpreted. Finally, on the basis of the theory of twofold-structure, the roles and attitudes of teachers and students are discussed.

The purpose of this study is to find out impact of level of awareness about old age, knowledge of the elderly and preparing for later life on college students in Korea. The study was composed of 133 students who were studying in 4-year system at colleges. Data were collected from October 1st to November 31st, 2019. Data analysis included an independent t-test, ANOVA, Pearson correlation coefficients and multiple regression using the SPSS 19.0 program. As a result of this study, factors influencing the subject's preparing for later life included knowledge of the elderly (β = 0.21, p = .012), men (β = 0.28, p = .001), and level of awareness about old age (β = 0.23, p =. 005), and the accounting power of these factors was 18% in total (F=9.14, p<.001). The results of this study suggest that understanding of the elderly must be improved in order to effectively prepare for later life and gender should be taken into account when planning for intervention.

The purpose of this study is to define a method of building an integrated service to provide various science and technology knowledge infrastructures that are helpful in R&D activities, and to show the cases that are adapted the methodologies. Knowledge infrastructures scattered throughout the entire R&D cycle, such as generating/development of ideas, finding the R&D project, performing the project, and spreading results, are segmented in terms of services, functions, information, and data, and links and converges to provide the knowledge infrastructure that desired by users in one place. We define the integrated service classification, integration level model, integrated architecture, and integrated user authentication system in consideration of logical linkage and integration rather than physical integration of individual knowledge infrastructures. Also, we considered the extensibility as the reference model for building of similar integrated service.

This study aimed to identify the level of knowledge, attitude toward the elderly, competence of carers, and the correlation between these variables. Research design employed a cross sectional descriptive study using structured questionnaires. Data were collected from 145 carers who have worked in long term care facilities from June 2014 to September 2014. Descriptive statistics, ANOVA, independent t-test, and Pearson correlation coefficient were performed to identify the relationship among variables. The competence of carers was related to a positive attitude and a higher knowledge of caring for the elderly. Therefore, educational content that considers improvement among carers who have a low level of educational status should be developed. It should require carers to have a positive attitude toward the elderly through improving the job environment in order to increase the quality of long term care.

The purpose of this study is to analyze pre-service science teachers' pedagogical content knowledge. For this study, two senior education students were selected. The data of this study were collected through interviews, CoRe questionnaire, and classroom observation recordings during the period of student-teacher practice. Data were analyzed using the constant comparative method. The results indicated that the two pre-service science teachers had low level pedagogical content knowledge. Two pre-service science teachers' knowledges of science curriculum were different from each other. Orientations toward teaching science shifted to undesirable direction after the experience of a student-teacher's practice-teaching. Their subject matter knowledges were imperfect. They also had low levels of knowledge of students' understanding.

Establishing and evaluating science education policies and revising and monitoring the effectiveness of science curriculum should be based upon the results of systematic and scientific research studies. Advanced nations have already been administering and developing national level science assessments for these purposes. The science assessments administered in Korea have been reported having many limitations and problems, and not succeeded in providing data for science education policy making and curriculum reform. The major purpose of the study is developing national level science knowledge assessment system in order to identify longitudinal trends of elementary and secondary school students science knowledge achievements. The research team consisted of science education experts and teachers from various school levels, decided the directions and major elements of national level science knowledge assessment with the consultation of educational evaluation experts. Item developing ability of the researchers was improved by seminars? and workshops on national assessment in advanced nations and developing skills of writing science items. Nearly 500 items were developed and revised. Pilot test was administered with 958 students at various school levels. 380 items were selected and tested with 8766 students, and the characteristics were analyzed in terms of item response theory. The target populations for national level science knowledge assessment are 5th-grade of elementary school, 2nd-grade of middle school, 1st and 2nd-grade of high school students. The proper period for the assessment is February every year. Multi-stage clustered sampling method is desirable and rotated forms are recommendable for the test format. Bridge items should be introduced to compare the results of multiple tests, and various grades. Anchor items should also be used for longitudinal interpretations of the results. The items for elementary school require low to medium abilities, for middle school and first grade of high school require medium to high abilities and for 2nd-grade of high school high abilities. The discrimination ability of the items developed is high.
