The purpose of this study is to investigate reunification perception among groups with different cognitive bias(anchoring bias) through empirical studies. This study assumes that cognitive bias occurs according to the content of N. Korea provided in school education, and that the cognitive bias formed in youth creates a difference in perception of N. Korea and reunification. For empirical study, a survey of reunification awareness conducted by the Institute for Peace an Unification Studies-Seoul National University was used, and the two groups are divided into A-group that chose "anti-communism or security" and B-group that did "reunification interests, multi-culturalism and understanding North Korea" according to N. Korea content which was encountered in school education during adolescence. A-group recognized N. Korea as a hostile target even after becoming an adult, while B-group regarded N. Korea as a one of dialogue and cooperation. This analysis illustrates the existence of cognitive bias between the two groups because of N. Korea content which was given in school education. A-group had a lower percentage than B-group in terms of the benefits of reunification to S. Korea and the need for more dialogue and compromise with N. Korea. However, there was no difference between two groups in terms of acceptance of N. Korean defectors. This research result could be a reference to the direction of school education policies relating to reunification in that early school education affects reunification awareness and perception related with N. Korea even in adulthood.

The purpose of this study is to investigate elementary students' perception on science-related career and teachers' perception on science-related career education. The subjects of this study were 196 5^th and 6^th elementary students and 100 elementary teachers. The results show that 28% of the students desire to have science-related career. More Boys desire science-related careers than girls, and more students with higher level of perception in their science achievement also do than lower level students. The reason students did not desired science-related career were that they were not interested in science and did not have fun in science. Students' perceptions in the factors of science-related career choice were mostly negative except socio-cultural factors. The results of teacher's perception show that 42% of the teachers conducted science-related career education. A lot of teacher did not conduct science-related career education since they perceived the career education were not necessary or important. Students' negative perception on the factors of science-related career choice and the teachers' low perception on necessity of science-related career education can negatively influence students' science-related career choice. The more efforts were required in order to increase positive perception on science-related career.

This paper investigated the views of effective mathematics instruction on the part of school administrators, and then compared and contrasted such views with those of elementary school teachers based on the previous study. A total of 32 school administrators participated in this study and responded to three types of the questionnaire. The results of this study showed that school administrators regarded good mathematics teaching as using concrete materials and teaching students to think. School administrators put their first priority on curriculum and content among four main domains of good mathematics teaching, and did on constructing curriculum among seven sub-domains of good mathematics teaching. They agreed that good mathematics teaching includes teaching by reconstructing the curriculum according to students' various levels and teaching to emphasize the connection among mathematical concepts. However, they thought that good mathematics teaching might not include teaching for fluent calculation or teaching in well-equipped learning environment. The results of comparison of perspectives regarding good mathematics teaching between school administrators and teachers showed remarkably similar tendency. However, a noticeable difference was that school administrators agreed more than elementary school teachers with regard to the 20 elements related to effective mathematics instruction. This paper closes with implications based on the similarities and differences regarding effective mathematics instruction perceived by school administrators and teachers.

This study aims to examine the current status of managing elementary school libraries in Busan and suggest the ways to improve it with the viewpoint of 'the five laws of library science'. The scope of study was set as the elementary school libraries in Busan, and the operation status of 304 elementary school libraries was analyzed. And for in-depth investigation, D elementary school library was examined as a case. The operation status of elementary school libraries in Busan was analyzed with the analysis elements; existence of school library, placement of teacher librarian, library collection, annual use, budget, and library seats for 6 years from 2016 to 2021. As a result, especially the placement rate of full-time teacher librarians was only 10.5%, indicating that the problem of manpower shortage was serious. As case study, the current state of managing D elementary school library was deeply investigated with perspectives of the first law and the third law of library science among Ranganathan's five laws of library science. With the first law, the investigation was divided into the aspects of open-shelf system, library location, library hours, furniture, and staff. With the third law, the investigation was done as the aspects of shelf arrangement, catalog, extended service, book selection. Especially, books with more than 50 copies for the program of reading one book each semester accounted for 4.8% of the total collection, showing the problem of unbalanced collection. As the result of this study, 'expanding the placement of teacher librarians', 'making better reading environment through remodeling', and 'balanced collection development' were suggested as the ways of developing school libraries.

Despite the rapid expansion of satellite images supply, the application of imagery is often restricted due to unautomated image processing. This paper presents the automated process for the selection of training areas which are essential to conducting supervised image classification. The training areas were selected based on the prior and cover information. After the selection, the training data were used to classify land cover in an urban area with the latest image and the classification accuracy was valuated. The automatic selection of training area was processed with following steps, 1) to redraw inner areas of prior land cover polygon with negative buffer (-15m) 2) to select the polygons with proper size of area ($2,000{\sim}200,000m^2$) 3) to calculate the mean and standard deviation of reflectance and NDVI of the polygons 4) to select the polygons having characteristic mean value of each land cover type with minimum standard deviation. The supervised image classification was conducted using the automatically selected training data with Sentinel-2 images in 2017. The accuracy of land cover classification was 86.9% ($\hat{K}=0.81$). The result shows that the process of automatic selection is effective in image processing and able to contribute to solving the bottleneck in the application of imagery.
