The purpose of this study was to analyze and derive pedagogical implications from elementary mathematics textbooks that align with the revised 2015 curriculum. Specifically, the focus was on the chapters related to simplifying fractions, finding a common denominator, and performing addition and subtraction of Fractions with Different Denominators. The analysis revealed that the overall structure of these chapters was similar across the textbooks, but variations existed in terms of the main activities and the textbook organization. Furthermore, different textbooks employed various types and quantities of visual representations. When designing lesson directions and content, it is crucial to consider the strengths and weaknesses of each visual representation.

This paper has two aims (1) to address the common European past by way of considering the development of the official archives of the European Union; and (2) to give specific attention to the activities of archivists in Germany. The EU archives contain the all the documents officially recording the common history of European integration from the establishment of the European Coal and Steel Community in 1951. It was at the beginning of the 1980s, thirty years after the production of these documents, however, that the Archives of the European Community (EC) began to be systematized for public use when the European University Institute in Florence in Italy was chosen as the deposit location for the archive. After the coming into effect of the Maastricht Treaty in 1993, the EC Archives were renamed as the EU Archives. Through the cooperation of the national archives of the each Member State of the EU with this EC Archives common norms regarding deposit were developed. This archives is a veritable gold mine for serious research into all and any official aspect of the institutional and policy history of today's EU, so for the formation of common European identity. The denazification process using the evidence of the archives contributed to the orientation of the New Germany towards Europe. The German archives then have been contributing to the redressing the past to a significant degree since after the Second World War. More recently, the establishment of the "Memory, Responsibility, and Future" Foundation in 2000 in Germany made possible cooperations with the archives of the East European countries and especially for the purpose of the providing evidence about former enforced workers under the Nazi regime. There has thus been developed European-wide networks among archives. These developments have furthered the common redressing of the European past and this process in turn has been contributing the enhancing the European spirit and identity. The thesis of this paper then is that historical research based on the EU archives and individual Member States can not only illuminate in great detail the stages of the history of European integration to date. The dissemination of such research can itself contribute to the process of the spreading of supranational ideas beyond Europe to other regions of the world.

The purpose of this study was to analyze the effects of mathematics learning through tessellation activities on the improvement of spatial sense and to find out a better mathematics teaching method that could further develop spatial sense. For this purpose, the following questions were attempted; Can mathematics learning using tessellation activities develop spatial sense? In odor to test this hypothesis, twenty-four fifth graders of a class were selected at random. And the experimental group was divided into four groups according to gender and academic performance. The groups were protested and post-tested to determine results based on the quasi-experimental design(i.e. one-group pretest-post test design). The process of this study was checking spatial sense for a common evaluation of experimental group. In this study, tangram, pattern block, and GSP was used for mathematics learning through tessellation activities during each independent-study, discretion-activity, and math class. The instrument used in this study was a spatial sense test and pretest and post-test were implemented with the same instrument(i.e. K-WISC-III Activity Test). In conclusion, mathematics learning through tessellation activities with tangram, pattern block, and GSP is an effective teaching and learning method for the improvement of the spatial sense.

Endogeneous activities of ${\beta}-galactosidase$-like enzyme in various tissues from several finfishes and shellfishes were examined by histochemical analysis based on X-gal staining and by fluorimetric measurement using 4-methylumbelliferyl-${\beta}$-D-galactoside (4-MUG). Species used in this study were 3 freshwater fishes, mud loach (Misgurnus mizolepis), common carp (Cyprinus carpio) and tilapia (Oreochromis niloticus) ; 3 marine fishes, olive flounder (Paralichthys olivaceus), stone flounder (Kareius bicoloratus) and marbled sole (Limanda yokohamae) ; and 4 shellfishes, abalone (Haliotis discus hannai), Pacific oyster (Crassoskra gigas), pearl oyster (Pinctada fucata martensii) and ark shell (Anadara broughtonii). The activities of ${\beta}-galactosidase$-like enzyme in all finfishes examined were significantly different among species, with the wide variations between tissues in a species. In general, the tissues such as kidney, intestine and liver were ones which showed the significantly higher values in 4-MUG fluorimetry and deeper staining patterns in X-gal analysis compared to other tissues. On the other hand, serum and muscle revealed the significantly lower activities than others did, regardless of species. Shellfishes were also found to have endogenous activities of ${\beta}-galactosidase$-like enzyme which were significantly varied depending on both species and organs in a species. Hepatopancreas from all shellfishes examined showed the deepest pattern in X-gal staining and also the highest value in 4-MUG analysis, while activities of ${\beta}-galactosidase$-like enzyme in adductor muscles and mantle muscles from all shellfish species in this study except Pacific oyster were negligible : Pacific oyster had the significant activity of this enzyme in muscle tissues. Putative endogenous lacZ fragment was amplified from both finfishes and shellfishes by polymerase chain reaction (PCR). The molecular size of PCR products was about 510 bp, and there was no difference in size among species examined.

The purpose of this study was to investigate how many kindergarten parents use after-school programs and specialization activities and to suggest effective policy improvement plans based on the results. After 693 parents were interviewed by the investigators, the collected data were presented by calculating the percentages, averages, and standard deviations. First of all, the results of after-school are presented. First, about 38.2% of the surveyed parents spent additional expenses to use after - school program, and the average of additional costs was about 62,850 won. When the cost burden and satisfaction were evaluated as 5 points, it was rated as normal. Second, the main reason for participating in the after-school program was both parents were working, followed by the parents' wishes for their children to spend time with their friends. Next, the results for specialization activities at kindergartens are presented. First, the proportion of children using after-school specialization activities was 68.2%, of which 79% were expenditures, the number of activities was 2.69, and the average cost was 83,540 won. Second, the most preferred after-school specialization activity by age group was English, and the most common reason for this was that the children liked to participate. Improvement of the educational contents suggested as the most important thing to improve after-school specialization activities. Lastly, the results showed that after-school specialization activities reduced parents' spending on private education. On the basis of the results, some discussions are presented included the development after-school programs focusing on the different needs of children and parents accordingly.

When developing a weapon system, a T&E(Test and Evaluation) can be performed using M&S for the test items that cannot be evaluated in the real world. In this case, the VV&A activities are required to prove the credibility of M&S for the T&E. Recently, the use of M&S has been increasing as the R&D trends of weapon systems are becoming more advanced. Therefore, the VV&A activities are also increasing. The VV&A activities aim to verify, validate, and accredit that the simulation can represent a real system and ensure credibility regarding its purpose and intention of use. VV&A activities are divided into V&V and Accreditation. When performing VV&A in the ADD (Agency for Defense Development), the V&V activities are performed by a separate department of the ADD and the accreditation activities are performed in the DTAQ (Defense Agency for Technology and Quality). This paper proposes a V&V process for a T&E of M&S that has been performed in ADD. The process is used to verify and validate the documents and data generated during the development process according to the accreditation criteria, and provides objective data that can be used to judge whether the accreditation decision and acceptance criteria are met.

This study analyzed illustrations presented in middle school science 14 paper textbooks and 14 digital textbooks under the 2015 revised curriculum in terms of gender stereotypes. In both paper and digital textbooks, the most common type of illustration was multiple pupils. For pupils, the frequency of gender was balanced in both paper and digital textbooks. However, there were differences among publishers in digital textbooks. In both paper and digital textbooks, girls showed a higher frequency than boys in learning activities. However, the opposite tendency was observed in non-learning activities. In particular, non-learning activities of digital textbooks showed gender imbalance among all publishers. In both paper and digital textbooks, behavioral characteristics were mostly described to be active without gender differences. But, there were differences among publishers in digital textbooks. For adults, men showed a higher frequency than women in both paper and digital textbooks. Gender frequency was balanced in family activities, however, men showed a higher frequency in social activities. Unlike paper textbooks, digital textbooks were gender balanced in occupational activities. In both paper and digital textbooks, the number of occupations in which men appeared more frequently was higher than that in which women appeared more frequently. Especially, men showed a higher frequency than women in both scientist and researcher. Behavioral characteristics were mostly biased in terms of gender in both paper and digital textbooks.

The main purpose of this study is to investigate the impact of COVID-19 risk perception on the operational activities and performance of incubator tenant companies during the early stages of the COVID-19 outbreak. The primary variables considered for the operational activities of incubator tenant companies include financial management, research and development, marketing, and downsizing. Financial and non-financial performance are the key variables for business performance. The research findings indicate that COVID-19 risk perception has a significant impact only on downsizing, but it does not significantly affect financial management, research and development, or marketing. Additionally, COVID-19 risk perception has a significantly negative impact on both financial and non-financial performance. Financial management and marketing significantly influence financial performance, while research and development and downsizing do not seem to have a significant impact on financial performance. Conversely, research and development, as well as marketing activities, significantly impact non-financial performance, while financial management and downsizing lack a significant influence on non-financial performance. Finally, when examining incubator tenant companies categorized into early-stage, leap-stage, and growth-stage companies, it was observed that only marketing activities have a common and significant impact on non-financial performance across all three types of companies.
