This study intends to evaluate the relationships between DLS union catalog and curricula and to suggest methods for its quality control. Comprehensiveness, specificity, currentness, and location of copies were selected for evaluation criteria. And this criteria were practiced to evaluate the relationships its indicators and library-based learning topics of social subjects in Seoul DLS. The results of analyses the DLS union catalog serves users with book-based learning information and lacks specificity to evaluate quality of learning materials. Especially the DLS don't satisfy the learning community with on-line contents. Accordingly it is essential to appoint teacher librarians understanding curricula and instructional values of the catalog for its quality control.

In this paper, using the theory of majorization, we discuss the Schur m power convexity for L-conjugate means of n variables and the Schur convexity for weighted L-conjugate means of n variables. As applications, we get several inequalities of general mean satisfying Schur convexity, and a few comparative inequalities about n variables Gini mean are established.

This study analyzes the relative importance and priorities on the early childhood teacher's rights using hierarchical analysis process(AHP) and suggests the theoretical and practical implications. We conducted the survey of the practitioners and academics in order to provide comprehensive and balanced discussion on the area of early childhood teacher's rights and sub-factors. The results of analyses show that the professional authority is the most important rights of establishing the early childhood teacher's rights. Second, the results show that the rights to guide young children and to decide on a teaching method are more important than other factors in professional authorities. Third, the results indicate that the right to have an their identity and the right of claim for remuneration are more important than others in the Publicness. In the labor factor, the experts emphasize that the right to make union for early childhood teachers is more important than the right of teachers' union for bargaining. These confirm the difference of the perceptions of the relative importance and priority on the areas of early childhood teacher's rights and sub-factors between the practitioners and academics. Based on these findings, we discuss the implications for improving the early childhood teacher's rights.

Most infrastructure structures were completed during periods of economic growth. The number of infrastructure structures reaching their lifespan is increasing, and the proportion of old structures is gradually increasing. The functions and performance of these structures at the time of design may deteriorate and may even lead to safety accidents. To prevent this repercussion, accurate inspection and appropriate repair are requisite. To this end, demand is increasing for computer vision and deep learning technology to accurately detect even minute cracks. However, deep learning algorithms require a large number of training data. In particular, label images indicating the location of cracks in the image are required. To secure a large number of those label images, a lot of labor and time are consumed. To reduce these costs as well as increase detection accuracy, this study proposed a learning structure based on mean teacher method. This learning structure was trained on a dataset of 900 labeled image dataset and 3000 unlabeled image dataset. The crack detection network model was evaluated on over 300 labeled image dataset, and the detection accuracy recorded a mean intersection over union of 89.23% and an F1 score of 89.12%. Through this experiment, it was confirmed that detection performance was improved compared to supervised learning. It is expected that this proposed method will be used in the future to reduce the cost required to secure label images.

This study analyzed the contents of changes in educational policy from the perspective of policy learning, based on the awareness of the lack of academic efforts to identify such phenomena despite repeated policy failures in educational policy. To this end, it has been more than 20 years since the policy was established, but it was analyzed using the policy analysis case of the teacher incentive policy, which still had severe conflicts between the government and teacher unions. As a result of the analysis, first, there were 11 changes in the policy content from the Kim Dae-jung administration to the Moon Jae-in administration. Whenever the government was newly launched, not only the contents of the policy for teacher incentives changed, but also the policy changes continued during the same government period. Second, when analyzing what kind of policy learning took place at the stage of change in each government's policy content, most of them were 'political policy learning' or 'instrumental policy learning'. Rather than a fundamental discussion about the goal of the policy, it has only repeated policy learning that adjusts only the ratio of differential payments to defend the teacher incentive policy. In order to recover from this current situation, this study suggests that it is necessary to present an alternative policy that can change the rigid society of teachers through 'social policy learning', which examines the basic values and strategies of teacher incentive policies.

The purpose of this study is to suggest practical plans to improve the school library consulting, especially in case of a teacher librarian is not assigned. As a result of analyses, consulting through methods of the School Library Assistant Group lacks spontaneity, expertise, council, and independence. Besides, each office of education operates it as a marketing. A main goal of school consulting is to foster independent problem- solving of individual schools. Accordingly, it is necessary to build an union management system, develop a standard staff manual, construct DLS based on-line consulting, and design educational training programs of consultants for its successful consulting.

The introduction of real numbers is one of the most difficult steps in the teaching of school mathematics since the mathematical justification of the extension from rational to real numbers requires the completeness property. The author elucidated what questions about real numbers can be unanswered as the "institutional didactic void" in school mathematics defining real numbers as the union of the rational and irrational numbers. The pre-service teachers' explanations on the extension from rational to real numbers and the raison d'$\hat{e}$tre of arbitrary non-recurring decimals showed the superficial and fragmentary understanding of real numbers. Connecting school mathematics to university mathematics via the didactic void, the author discussed how pre-service teachers could break the illusion of transparency about the real number.

One of the historical origins of the modern science education was investigated in this paper. From the view point of the pansophistic educational philosophy which emphasized "man should teach completely all things to all mankind(Omnes, Omnia, omnino)", J.A.Comenius proposed in his book "Didactica magna"(1658) that 'physica' should be learned as one of the most important school subjects. He suggested the completion of human being as a wholeness of the universe could be achieved through the physics teaching. His ideas of science education was, however, directed not to the 'rational konwledge' about the natural world, but to the 'divine wisdom'. His main thoughts and influences on science education can be summarized as follows: 1) The human being as a God's image should know the divinely created nature, because the invisible God's existence can be sensorially recognized in the nature. 2) Physics or science should be regarded as more important objects than verbal learning in general school education. 3) The cognitive union between the words('representative' or 'das Dargestellte') and things('presentative' or 'das Dargebotene') can be achieved through the objects lesson ('Anschauungsunterricht') 4) The realistic and sensor-cognitive learning theory of the object lesson is yet very important especially in the science education of elementary school, even though the inquiry learning process has became more important in the last years. 5) The religious aspect of his idea could not satisfy the social needs of industrialization and the development of professonal technics in the 18 to 19th century.

The article substantiates the feasibility of using and actively implementing innovative technologies in the practice of organizing the educational process. The need for the use of telecommunication technologies, which provide constant communication between students and the teacher outside the classroom, has been identified. Particular attention is paid to the latest approaches to the use of various forms of multimedia technologies in student education, which intensify the process of acceptance and assimilation of educational material by foreign students. The advantages of using innovative means of distance education are determined, which thanks to modern electronic educational systems allow students to receive quality higher education. Innovative technologies promote the development of cognitive interest in students, they learn to systematize and summarize the material studied, discuss and debate. In this regard, the reorientation of the system of higher education in Europe towards innovation is becoming the most important tool in ensuring the competitiveness of graduates in the labor market. In addition, the investment attractiveness of a university often depends on the innovative nature of the development of scientific, educational and practical activities of the subjects of the educational process, their inclusion in the national innovation system. The article analyzes that in the universities of the European Union in the training of specialists in the management of basic interactive methods, forms and tools are binary lecture, briefing, webinar, video conference, video lecture, virtual consultation, virtual tutorial, slide lecture, comp. utheric tests. Various classes on slide technology took active forms during the training of management specialists.

In the Soviet Union School health services are provided as an integral part of the health care delivery system, which is under the Ministry of Health. This paper presents an overview of the Soviet Union's health care delivery system, the model for the delivery of school health service, the role and training of school personnel involved in school health services and implications the Soviet model may have for the countries. 1. School health services are a part overall Soviet health system under the Ministry of Health. 2. Municipal and rural health departments implement programs at the local level. Diagnosis and treatment are conducted through "polyclinics" that are outreach divisions of a district hospital. 3. Education institutions for the development of health manpower, including medical schools and nursing schools, are under the Ministry of Health, as are medical and scientific search institutes.
