Recently, in school mathematics, classes using mathematical modeling are attracting attention to improve students' mathematical problem-solving skills. However, existing preceding studies have been conducted mainly on elementary, middle, and high school or in-service teachers, so it may be limited to apply the contents and results of the research as it is to pre-service teachers, who are future professors. Therefore, this study examined the school days' experiences of mathematical modeling for pre-service elementary school teachers. In addition, in order to provide a positive experience for mathematical modeling, mathematical modeling problem creation activities were conducted through group activities, and the results and their perceptions were examined. As a result of the study, elementary school preservice teachers had very little experience with mathematical modeling activities during their elementary, middle, and high school days. It was found that there is a deficiency in creating an appropriate mathematical modeling problem suitable for the level of elementary school students. In addition, it was found that they had a positive perception of mathematical modeling after participating in the study. Based on these results, implications for the training process for preservice teachers were suggested.

In this study, we explored factors that affect high school student's affective attitude on mathematics with respect to the school mathematics instructoin, school mathematics assessment, mathematics textbook, private mathematics education, college entrance and career, and social atmosphere. Considering students' grade, major, academic level, gender, and school location, 1,029 high school students participated in the survey. To analyze the survey results, descriptive statistics, t-test, ANOVA, and chi-square test were conducted using SPSS ver 29.0. Results are as follows. First, generally, college entrance and career and school mathematics instruction affected students' affective attitude on mathematics. Second, according to student's academic level and gender, there was a statistically significant difference in the factors affecting the affective attitude on mathematics. Third, according to students' background, there was a statistically significant difference in students' responses to sub-categories of each factor. We suggested that to improve student's affective attitude on mathematics, diversity of the school mathematics instruction, improvement of the mathematics textbook, student's appropriate participation in the private mathematics education, improvement of student's perception of the utilization of the mathematics in the future and the importance of the mathemaitcs in the society, and parents' emotional support are needed.

This study aims to introduce and assess CNN Deep Learning methods to analyze visual landscape images on social media with embedded user perceptions and experiences. This study analyzed visual landscape images by focusing on a healing place. For the study, seven adjectives related to healing were selected through text mining and consideration of previous studies. Subsequently, 50 evaluators were recruited to build a Deep Learning image. Evaluators were asked to collect three images most suitable for 'healing', 'healing landscape', and 'healing place' on portal sites. The collected images were refined and a data augmentation process was applied to build a CNN model. After that, 15,097 images of 'healing' and 'healing landscape' on portal sites were collected and classified to analyze the visual landscape of a healing place. As a result of the study, 'quiet' was the highest in the category except 'other' and 'indoor' with 2,093 (22%), followed by 'open', 'joyful', 'comfortable', 'clean', 'natural', and 'beautiful'. It was found through research that CNN Deep Learning is an analysis method that can derive results from visual landscape image analysis. It also suggested that it is one way to supplement the existing visual landscape analysis method, and suggests in-depth and diverse visual landscape analysis in the future by establishing a landscape image learning dataset.

There could be different ways of perception, emotions, and behaviors facing on unfair situation according to the culture background by which people have been affected. We investigated whether definition, feelings, and behaviors in 4 countries (Korea, China, Japan, and the US) would differ in terms of unfair situations. We further examined the relationship between new self-construal model (subjectivity-objectivity-autonomy model) and behaviors resulted from unfair situations. Three hundred seventeen participants (87 Koreans, 71 Chinese, 80 Japanese, and 79 Americans) took part in this research. We found that all countries defined unfair situation as "having a disadvantage or blame that one did not done by him or her" with the highest percentage, but there was a different percentage according to countries. Next, Chinese felt disappointment or betray from the situations highly while others expressed anger with the largest portion. In the area of behaviors, three countries in Asia answered "no behaviors" with the highest percentage while Americans mostly responded "direct expressions". In terms of self-construal model, subjective self was high in Chinese and Koreans while autonomy was high in Chinese and American. Japanese showed objective self with the highest. Implications and future research are discussed.

This study investigated the overall perceptions of pre-service school librarian teacher on the current education practicum through semi-structured in-depth interviews and suggested improvements to the educational practicum system. For this purpose, interview data were collected from 28 pre-service school librarian teacher (6 teachers' colleges, 14 taking teaching qualification courses, and 8 graduate school of education) who participated in educational practicum in school libraries, and a research method that combines qualitative analysis techniques with text network analysis was applied. The results of the study showed that pre-service school librarian teacher believe that educational practicum can prepare them for various field experiences and cultivate their ability to cope with situations they will encounter in the future. Through qualitative inquiry, we were able to identify their perceptions of school field practicum as a whole, their perceptions of the school field practicum, and their perceptions of educational service activities. Based on this, to improve the current problems of educational practice, we suggested expanding the period of school internship program, distributing the time, establishing a full-time practice system, having continuous discussions with field teachers, and developing a systematic school field practicum.

The present study investigated individuals' perception of important social issues in Korea. Based on previous research(Hahn, 1994; Hahn & Kang, 2000), a checklist containing 370 social issues was created. This checklist was administered to 1600 Koreans(812 college students, 788 adults) residing in 5 regional areas in Korea during the period of December 2004 and February 2005. Data were analyzed by the respondents' age, sex, and residing areas, and findings were compared to those of the two previous studies conducted in 1994 and 1999. Major findings of the study are as follows. First, across the three surveys, over 50% of the respondents consistently indicated the following four items as important social issues in the Korean society: political corruption, environmental pollution, the education system that is driven too much for college entrance, employment difficulty for local college graduates. Second, more than 50% of the respondents in the current survey indicated the following 12 items as important social issues that must be resolved: high unemployment rate, political corruption, environmental pollution, education system, overall difficulty of getting jobs, the nation's distrust in politics, hardships of life among the working classes, political incompetence, people with defective personal credit standings, employment difficulty for local college graduates, political instability, corruption of public servants. Third, analyses on the top 30 social issues across the three surveys revealed a positive and significant rank-order correlation for a five-year period(i.e., 1994-1999, 1999-2004), but not for a ten-year period(i.e., 1994-2004). Implications of the study and directions for future research are discussed.

During the COVID-19 period, public libraries produced and provided a variety of online contents to users as an alternative to offline services. The purpose of this study was to analyze the overall management of online contents in public libraries in the post COVID-19 period and to provide a methodological basis for improving online contents management. This study surveyed the overall current state of online content management in 305 public libraries in terms of production, services, and preservation. We also analyzed the librarian's perception of the online contents management process. As a result of the analysis even after the COVID-19 period, public libraries are efficiently producing and providing online contents and are actively providing this through the library website and social media. In addition, librarians recognized that online contents produced by public libraries are valuable as library resources and predicted that the online content would be produced more in the future. Also, they faced difficulties in production and management due to a lack of professional capabilities and extra workload, but they have recognized the high need for online contents management. Online contents is leading a paradigm shift in public library services. Therefore, attention and effort to activate online content is no longer an option but a necessity.

Under the Trump administration, the U.S. has made clear that "China is America's strategic competitor, revisionist power and a major challenge to America's prosperity and security." The Biden administration has largely inherited this perception of China. China has also responded without backing down. Therefore, the U.S.-China strategic competition has become the most important background factor in the international system and has a great impact on the security situation in Northeast Asia. Nevertheless, if you look at the recent process of establishing trilateral security cooperation among ROK, the U.S. and Japan, we can find that ROK's foreign strategy adjustment has played a key role. This is because establishing trilateral security cooperation among ROK, the U.S. and Japan depends on improving ROK-Japan relations. And the Yoon Suk Yeol government is pushing for rapid improvement in ROK-Japan relations regardless of domestic political constraints. The trilateral summit at Camp David laid the groundwork for future cooperation among ROK, the U.S. and Japan in security and other broader areas. China is strongly dissatisfied with the formation of trilateral security cooperation among ROK, the U.S. and Japan. However, this paper argues that although ROK agrees to form trilateral security cooperation with the U.S. and Japan, ROK's strategic objectives are not exactly the same as those of the U.S. and Japan. For example, looking back at the development of the U.S.-Japan alliance after the end of the Cold War, both the U.S. and Japan share similar views and perceptions of China's rise. The real goal of the strengthening of the U.S.-Japan alliance in recent years is also how to cope with China's rise. On the other hand, ROK's previous administrations have been negative about trilateral security cooperation with the U.S. and Japan. This is because ROK's main strategic goal is to reduce or eliminate threats from DPRK rather than respond to China. Faced with increasing DPRK's provocations and threats, more than half of South Koreans are in favor of reinforcing trilateral security cooperation with the U.S. and Japan to contain or mitigate threats from DPRK. As a result, if North Korea's nuclear and missile threats to ROK continue, then ROK's foreign strategy is likely to be to strengthen trilateral security cooperation between the U.S. and Japan to ensure its own safety and survival. If China wants to reduce the strategic pressure from the trilateral security cooperation among ROK, the U.S. and Japan, the best way is to reduce DPRK's provocations and threats to ROK and play a more substantive role in getting DPRK to give up its nuclear program.
