학생들이 수학수업에 참여도를 높이고 효율성을 극대화하기 위해 그들의 마음을 움직여, 인생을 살아가며 내재된 수학 잠재능력을 깨워 쓸모 있고 훌륭한 사람으로 이끌어주고 수학을 다시 생각할 기회를 주려고 한다. 수학에 관심을 갖고 수학을 하도록 안내하는데 있어, 개인마다 내재되어 있는 수학적 잠재력을 깨울 수 있게 하는 방법에 대해 알아보려고 한다. 각 항목에 대한 구체적인 프로그램을 만들고, 그것을 시행하는 데는 상당한 어려움이 따르지만, 그 결과가 만족스러울지 학생들에게 알아보았다. 중복되는 주제가 서로 도움을 주고 시너지 효과를 주므로, 하나씩 읽어가며 좋은 결과를 기대하면 각 주제가 서로 상승 작용을 일으키고 도움을 준다. 물론 수학에 관심이 덜하고 수학학습 능력이 부족한 학생들을 깨우치기 위한 시도이지만, 16개 큰 주제에 딸린 작은 주제 중 어느 하나를 글쓰기를 통해, 그 글에 대해 서로 발표하고 비판하며 수학 잠재력을 한 사람이라도 더 깨우치게 되었다.

Purpose: The purpose of this study is to identify research trends related to ESG by domestic and overseas researchers so far, and to present research directions and clues for the possibility of applying ESG to Korean companies in the future and ESG practice through comparison of derived topics. Research design, data and methodology: In this study, as of October 20, 2022, after searching for the keyword 'ESG' in 'scienceON', 341 domestic papers with English abstracts and 1,173 overseas papers were extracted. For analysis, word frequency analysis, word co-occurrence frequency analysis, BERTopic, LDA, and OLS regression analysis were performed to confirm trends for each topic using Python 3.7. Results: As a result of word frequency analysis, It was found that words such as management, company, performance, and value were commonly used in both domestic and overseas papers. In domestic papers, words such as activity and responsibility, and in overseas papers, words such as sustainability, impact, and development were included in the top 20 words. As a result of analyzing the co-occurrence frequency of words, it was confirmed that domestic papers were related mainly to words such as company, management, and activity, and overseas papers were related to words such as investment, sustainability, and performance. As a result of topic modeling, 3 topics such as named ESG from the corporate perspective were derived for domestic papers, and a total of 7 topics such as named sustainable investment for overseas papers were derived. As a result of the annual trend analysis, each topic did not show a relatively increasing or decreasing tendency, confirming that all topics were neutral. Conclusions: The results of this study confirmed that although it is desirable that domestic papers have recently started research on consumers, the subject diversity is lower than that of overseas papers. Therefore, it is suggested that future research needs to approach various topics such as forecasting future risks related to ESG and corporate evaluation methods.

Purpose: The purpose of this study is to provide information for other journals as well as the continuous development of distribution science research by confirming the globalization performance of the Journal of Distribution Science (JDS), the main journal of KODISA. Research Design, Data, and Methodology: A total of 863 papers published in JDS from 2011 to 2021 searched by scienceON were divided into 4 periods and analyzed under the headings of submission system, standardity, collaboration, and degree of achievement of publication goals. SPSS 24.0 and R 4.1.1 package were used to perform the publication frequency analysis, crosstab-analysis, keyword frequency analysis, and LDA topic modeling were performed. In addition, trend analysis with weight applied to each word was performed. Results: It was found that the ratio of English-written papers, which is the indicator of a journal's starndardity, is continuously increasing, and the ratio of overseas authors, which is the indicator of collaboration, is also continuously increasing. It was confirmed through keyword trend analysis by period and LDA topic modeling results - which were weighted to confirm the degree of achievement of the journal's publication goal - that the articles published by the journal has been in agreement with monthly research topic proposed by JDS. Conclusion: By examining the five criteria for globalization, it can be concluded that JDS's efforts for globalization are achieving significant results and providing effective directions for other academic journals. However, in order for JDS to become a top academic journal, it was suggested that efforts should be made to establish a system for collaborative research by domestic and foreign authors, as well as to provide a clear definition for the monthly research topics and classification of sub-topics.

This study examines a Korean elementary school EFL teacher's practice of teacher-based assessment (TBA), a subject which has been little researched despite the authorities' strong call for its implementation. The classroom interactions for TBA were observed and audio-recorded in eight fifth-grade classes between March and June 2010. Additionally, the teacher and students were interviewed in a semi-structured way. The results showed that the teacher used three types of TBA: assessment of individual students on different topics, assessment of the entire class on the same topic, and assessment of individual students on the same topic. Due mainly to time constraints during class time and classroom management issues, the teacher preferred implementing the first two types of TBA. During the practice of the types, the teacher provided prompts or posed questions in ways that elicited responses which were short in length and easy. Although the third type of TBA was perceived by both the teacher and students as helping students enhance their EFL proficiency and was the most favored by the students, it was viewed by the teacher as having the potential of causing classroom management difficulties. Based on the findings, a number of implications are suggested.

Photovoltaic devices are promising candidates as affordable and large-area renewable energy sources, which can replace the fossil-fuel-based resources. Especially, thin film solar cells have attracted increasing research attention, since they have a great advantage of low production cost. From the physical point of view, the photovoltaic devices can provide us interesting questions, how to enhance the light absorption and the carrier collection efficiency. A lot of approaches would be possible to address these issues. We have focused on two major topics relevant to photovoltaic device physics; (1) light management using surface plasmons and (2) junction characterizations aiming at proper interface engineering. Regarding the first topic, we have investigated the influences of Ag under-layer morphology on optical properties of ZnO thin films. The experimental results suggested that coupling between the surface plasmon polaritons at the ZnO/Ag interface and excitons in ZnO should play important roles in reflectivity of the ZnO/Ag thin films, which are widely used back reflector structures in thin film solar cells. For the second topic, we have carried out scanning probe microscopy studies of Schottky junctions consisting of photovoltaic materials. Such a research is very helpful to understand the correlation between the defects (e.g., grain boundaries) and local electrical properties. We will introduce some of the recent experimental results and discuss the physical significance.

Purpose: The purpose of this study is to explore the trends of research related to ethical topics in Korean nursing students. Methods: A total of 131 articles that were published from 2000 to 2020 were analyzed and summarized according to publishing type, research design, subject, data analysis method, main research topic, research variables and instrument. Results: Most studies were journal articles (93.9%) and their most frequent research design was survey (75.7%). The research subjects covered all grades (35.1%) or they were divided between clinical nursing practicum (29.8%) or not (21.4%). The main research topics were biomedical ethics, ethical values, moral judgment and ethics education. Recently, ethical decision making and practical ability in nursing practice were reported. The instruments for measuring variables were limited and the same tools were used several times. Conclusion: Based on the findings of this study, it is suggested that the selection of various research topics and the application of research methods related to ethics for nursing students will continue in response to rapidly changing social phenomena in the future. In particular, it is necessary that research related to ethical and practical ability as well as ethical attitudes and perceptions of nursing students be actively carried out.
