The purpose of this study is to search for the direction of informal science education research by analyzing them from the educational perspectives of informal science education. For this purpose, this study analyzed 144 journals related to informal science education that have been issued in the last six years in terms of educational perspectives. As a result, this study found a tendency for studies to be biased towards a few educational perspectives such as scientific practice participation, emotional enhancement, and understanding of knowledge, while studies on the understanding of nature of science have been conducted in a few cases. This tendency was also found in the analysis of the detailed media in each field, however, the biased educational perspectives varied from media to media. Therefore, in order to understand various aspects of informal science education itself, which is not a subsidy of formal school education, and to deeply understand what each media is trying to pursue, it should be done with various educational perspectives in each media study.

The purpose of this study is to review the trend in comparative education research related to curriculum published in the Korean Journal of Comparative Education, and to critically analyze its characteristics from the postcolonial perspectives. In this study, I analyzed 61 articles published in this journal from 1995 to 2016. The result showed that comparative studies related to curriculum were conducted mainly by benchmarking policies or contents related to curriculum and textbooks of Western countries including North America and Europe as well as Japan which colonized Korea. In addition, although Korea has been changing into multicultural society, studies on Asian countries such as China and Vietnam which are the nationalities of many foreigners living in Korea were rare. Based on the results, this study suggested that the expansion of comparative education research subjects, overcoming of coloniality in comparative education, and ontological reflection of comparative education researchers are necessary.

The longitudinal trend of elementary and secondary students' science process skills were investigated to monitor the progress of science learning. Science process skill test, developedin an earlier study on developing a national science process skills assessment system,was revised and administered for the study on March, 1999. Subjects were sampled nation wide according to sex and region. The results of this assessments were compared to those administered on February, 1997. The results showed little difference on science process skills among elementary school students. However, secondary students showed marked increase in science process skills. More systematic and long-term research for assessing science process skills should be planned and performed periodically to provide empirical and foundational data for educational policy making.

To understand the research trend of environmental education(EE) during last two decades, we analyzed a total of 801 research papers published from 1990 to 2008, 418 research papers from "Hwankyungkyouk" and 393 research papers from "The Journal of Environmental Education(JEE)", respectively. The majority of the authors in both journals majored in EE, followed by authors of science education major in "Hwankyungkyouk" and authors of social science major in JEE. In both journals, more researches were data-collected by quantitative method rather than qualitative method. In particular, the ratio of researches by qualitative method have been dramatically increased since the mid 1990s. The significance test was less used in Korean EE researches than those in JEE. In both journals, more EE researches for elementary and secondary school students were accomplished, which tended to be more salient in Korea. The result of the analysis of 119 EE programs in both journals proposed that EE program needs to be developed more diversely in content as well as in educational method.

Objectives: The purpose of this study is to analyze the research trends on oral health literacy in South Korea and to suggest the direction of future research, Methods: The literatures were searched using KISS, RISS, KMBASE, KoreaMed, Nanet and NDSL. A total of 17,433 documents were retrieved by database searching. The final 34 literatures that satisfied the inclusion criteria were selected for analyzing. A content analysis was performed on 34 literatures on the topics of oral health literacy which had been published from 2012 to 2019. Results: Most of the 34 literatures, 23 articles and 11 thesises were descriptive-correlation studies, but there was no intervention study. The participants studied in the selected literatures were mostly adults followed by elderly and other groups including foreigner. More troubling sufficient samples and sampling methods were lacking at the population level. The validation of the used health literacy instruments was not sufficient. Conclusions: The unification of translation terminology for oral health literacy and the standardized instrument to test oral health literacy are needed. And to improve the level of oral health literacy, studies should be conducted using various variables. It is also necessary to develop the oral health education programs that can improve the level of oral health literacy. In the future, meta-analysis on the oral health literacy are needed for cumulating findings and drawing more reliable and general conclusions.

In this study, we applied the long short-term memory (LSTM) model to classify the cryptocurrency price time series. We collected historic cryptocurrency price time series data and preprocessed them in order to make them clean for use as train and target data. After such preprocessing, the price time series data were systematically encoded into the three-dimensional price tensor representing the past price changes of cryptocurrencies. We also presented our LSTM model structure as well as how to use such price tensor as input data of the LSTM model. In particular, a grid search-based k-fold cross-validation technique was applied to find the most suitable LSTM model parameters. Lastly, through the comparison of the f1-score values, our study showed that the LSTM model outperforms the gradient boosting model, a general machine learning model known to have relatively good prediction performance, for the time series classification of the cryptocurrency price trend. With the LSTM model, we got a performance improvement of about 7% compared to using the GB model.
