In the knowledge-based society, IT literacy and application of a person become a measure of personal competitiveness. As IT industry is of great important nationally, many countries are trying to make an effort to promote IT industry. In this sense, identification and fostering of the gifted children in IT become an important national task since, in IT industry, usually only a few prodigies have led whole IT industry. Currently gifted education aims for convergent gifted education according to government policy. The purpose of this paper is to investigate correlation of information subject and convergent subject for the gifted children in IT. For this purpose, the gifted children in IT who attended a gifted science education center attached to a university at Seoul Metropolitan Area are selected. Their grades during their the period of attendance are collected and analysed. The statistical results show that there is a meaningful correlation between information subject and convergent subject for the gifted children in IT. It means that the higher scores information subject is, the higher scores convergent subject is. The results can be used to make or change gifted curriculum and education contents for gifted IT education.

The purpose of this study was to understand middle school Home Economics teachers' family value and needs on learning objectives of family life area, and to identify the relationship between the two. Data was collected from the survey mailed to the teachers responsible for family life area in $\lceil$Technology/Home Economics$\rfloor$ in middle schools in Korea. The collected 312 questionnaires were used for final analysis. SPSS/WIN program was used for calculating average, standard deviation, percentage, t-test, ANOVA with post-verification scheffe., and correlation analysis. Followings are the summary of the results of this study. Firstly, the family value of middle school Home Economics teachers was relatively modern. They had very modem sense of value in all of the sub-areas such as sense of value on marriage. on gender role. on children, on filial love, and familism. Secondly, regarding needs on family life area of learning objects of Home Economics teachers, the requirement on emancipatory system of action was the highest. technical system of action was the next, and Communicative System of Action was the lowest. Thirdly, in the relationship between the needs of teaming objects of family life area and the family value, the needs of technical and interpretive behavioral system had few things to do with the family value. However. the needs on teaming object needs of emancipatory system of action was higher as the family value was modern. The trend in the relationship with needs was same in all the sub-areas such as sense of value on marriage, on gender role, on children. on filial love, and familism. However, the family value and the achievement level of family life area goals did not show significant correlation. Fourthly, regarding the family value and the needs on teaming objectives of family life area of middle school Home Economics teachers, those who were female, who had certificates for Home Economics Teaching, who were young and who had less experiences in teaching had more modem family value and required more teaming objectives in emancipatory system of action. Considering the results of the study, it is needed to emphasize the learning objects of emancipatory system of action in family life education by inducing consensus on the proposition that Home Economics subject is a critical and practical subject. To do this. it is needed to provide Home Economics teachers with emancipatory interest and mature family value through educating and refreshing them. It is desirable to separate Technology and Home Economics so that certificated Home Economics teachers could teach family life area. In that case they can teach the subject in the point of practical criticism. If the area is to be taught by other subject teachers there should be enough understanding on the philosophy and nature of Home Economics subject beforehand.

In terms of making more various geometrical figures than existing Tangram, Sphinx Puzzle has been used as a material for the gifted education. The main research subject of this paper is to verify how many convex polygons can be made by all pieces of a Sphinx Puzzle. There are several previous researches which dealt with this research subject, but they did not account for the clear reasons on the elementary level. In this thesis, I suggest using unit area and minimum area which can be proved on the elementary levels to account for this research subject. Also, I composed the program for the mathematically gifted elementary students, regarding the subject. I figured out whether they can make the mathematical justifications. I applied this program for three 6th grade students who are in the gifted class of the G district office of education. As a consequence, I found that it is possible for some mathematically gifted elementary students to justify that the number of convex polygons that can be made by a Sphinx Puzzle is at best 27 on elementary level.

This thesis is to presented a theoretical fundamental of an assessment criteria available to a conventional curriculum because informatics subject matter education became it. We analyzed Bloom's Knowledge Dimension, Taxonomy that have suggested most general theoretical base in the educational assessment area. Also a programming area which can improve computational thinking can be the most important chapter of the informatics subject matter. Thus this thesis applied Bloom's theory to KAIE's informatics subject matter curriculum made by 2017. And the result of the qualitative research through the expert panel was 14 items, 87% of Conceptual, Procedural Knowledge and 12 items, 75% of Understand, Apply Taxonomy of Bloom's Theories in the 16 items of the curriculum outlines. Applying Bloom Criteria to like these can provide theoretical fundamental of assessment trend, development of assessment tool requested in the conventional education.

Introduction: Research on dental bone graft material has been actively conducted. Recently, demineralized dentin matrix material has been developed and introduced. This study examined the effect of demineralized dentin matrix material on bone healing. Subjects and Methods: The patients who received no treatment after extraction were used as the control group and patients who underwent demineralized dentin matrix material application in the extraction socket after extraction were used as the experimental group. Panorama radiography was performed at the baseline and at 3.5 months after graft material placement and CT was taken at 3.5 months after graft material placement for a radiologic evaluation. Bony tissue specimens were collected from the alveolar crest in the middle of the extraction socket using a 2 mm trephine bur after 3.5 months for the histology and hostomorphometric study. Results: 1. On the panoramic view, a higher bone density was observed in the subject group. 2. On the panoramic view, the bone density increased significantly in the extraction socket, from the baseline to 3.5 months: a 7 and 10 gray-level scale was observed in the control and experimental group, respectively (P<0.05). 3. The CT view evaluation at 3.5 months revealed significantly higher bone density in the subject group than the control group (P<0.05). 4. The histological findings showed more active new bone and lamellar bone formation in the subject group. Dentin with osteoinduction ability and enamel with osteoconduction ability appeared. 5. On histomorphometric analysis, the subject group showed significantly more new bone, lamellar bone area and lower soft tissue area (P<0.05). The difference between the groups was significant (P<0.05). Conclusion: Bone healing was improved after the application of demineralized dentin matrix material and there was active new bone and lamellar bone formation.

This study describes an approach for comparative bibliometric analysis of scientific publications related to (i) individual or several departments comprising a university, and (ii) broader integrated subject areas using multiple disciplinary schemes. It uses a custom dataset of scientific publications (ca. 15,000 articles and reviews, published during 2009-2013, and recorded in the Web of Science Core Collections) with author affiliations to the research departments, dedicated to science, technology, engineering, mathematics, and medicine (STEMM), of a comprehensive university. The dataset was subjected, at first, to the department level and discipline level analyses using the newly available KAKEN-L3 classification (based on MEXT/JSPS Grants-in-Aid system), hierarchical clustering, correspondence analysis to decipher the major departmental and disciplinary clusters, and visualization of the department-discipline relationships using two-dimensional stacked bar diagrams. The next step involved the creation of subsets covering integrated subject areas and a comparative analysis of departmental contributions to a specific area (medical, health and life science) using several disciplinary schemes: Essential Science Indicators (ESI) 22 research fields, SCOPUS 27 subject areas, OECD Frascati 38 subordinate research fields, and KAKEN-L3 66 subject categories. To illustrate the effective use of the science mapping techniques, the same subset for medical, health and life science area was subjected to network analyses for co-occurrences of keywords, bibliographic coupling of the publication sources, and co-citation of sources in the reference lists. The science mapping approach demonstrates the ways to extract information on the prolific research themes, the most frequently used journals for publishing research findings, and the knowledge base underlying the research activities covered by the publications concerned.

General-purpose classification scheme encompasses all subject areas, While the whole classification scheme is constructed by library studies experts, structure and preparation of each specific subject area's classification should be referenced to that specific subject. In order for the whole system to be practical and useful classification scheme, not just a simple collection of each subject area's scheme, it is necessary to set the rule for properly distributing the amount of classification items, and the collections assigned to these items. The rule to set the distribution of items based on the amount of document collections is called 'literary warrant'. This study examines actual status of assignment of each classification items to information resources, as a result of application of Korean Decimal Classification, and then suggests a way to improve these practices.

Purpose : The purpose of this study was to establish a model of the predictive factors for success or failure of examinees undertaking the Korean physical therapist licensing examination (KPTLE). Additionally, we assessed the pass/fail cut-off point. Methods : We analyzed the results of 10,881 examinees who undertook the KPTLE, using data provided by the Korea Health Personnel Licensing Examination Institute. The target variable was the test result (pass or fail), and the input variables were: sex, age, test subject, and total score. Frequency analysis, chi-square test, descriptive statistics, independent t-test, correlation analysis, binary logistic regression, and receiver operating characteristic (ROC) curve analyses were performed on the data. Results : Sex and age were not significant predictors of attaining a pass (p>.05). The test subjects with the highest probability of passing were, in order, medical regulation (MR) (Odds ratio (OR)=2.91, p<.001), foundations of physical therapy (FPT) (OR=2.86, p<.001), diagnosis and evaluation for physical therapy (DEPT) (OR=2.74, p<.001), physical therapy intervention (PTI) (OR=2.66, p<.001), and practical examination (PE) (OR=1.24, p<.001). The cut-off points for each subject were: FPT, 32.50; DEPT, 29.50; PTI, 44.50; MR, 14.50; and PE, 50.50. The total score (TS) was 164.50. The sensitivity, specificity, and the classification accuracy of the prediction model was 99 %, 98 %, and 99 %, respectively, indicating high accuracy. Area under the curve (AUC) values for each subject were: FPT, .958; DEPT, .968; PTI, .984; MR, .885; PE, .962; and TS, .998, indicating a high degree of fit. Conclusion : In our study, the predictive factors for passing KPTLE were identified, and the optimal cut-off point was calculated for each subject. Logistic regression was adequate to explain the predictive model. These results will provide universities and examinees with useful information for predicting their success or failure in the KPTLE.

The purpose of the research is examine the effect of STEM integration education using educatinal robot on academic achievement and subject Attitude of mathematics and science. The participants were 73 students of two classes, sampled from 6th graders of an elementary school. They were divided into a control group who learned a traditional mathematics and sciences education based textbooks and an experimental group who learned STEM integration education using educational robot during 12 sessions. The results are summarized as follows : First, there is a significant difference in academic achievement between two groups. STEM integration education using educational robot based group accomplished higher achievement than textbook based instruction group. Especially, post test analyzes results on the three factors of academic achievement, knowledge, understanding and adaptation, indicate statistically meaningful difference between two groups in understanding and adaptation area except knowledge area. Second, it shows that it greatly affected a positive influence on experimental group's attitude toward subjects in affective area. So we can expect STEM integration education using educational robot to be an alternative for stimulating children's higher learning interest on mathematics and science subject.
