The purpose of this study lies in touching the study trend of Chinese education technology through the analysis on present situation of the study in Chinese education technology, and is to suggest the direction for the its further study and development. In order to achieve these kinds of study purpose, the frames have been set to grasp the features and trend of Chinese educational technology in such as 4 aspects of educational technology definition, curriculum and the cultivation of genuine individuals, study zone aspect and the method, and in order to grasp, in the comparison with the countries of advanced educational technology such as Korea, America etc., the progressive features and the trend of development of Chinese educational technology have been analyzed. As a result of the analysis, it has been found that Chinese educational technology has the different features in the study and development of educational technology of Korea and America in the abovementioned 4aspects. First, in the education technology comprehension, it differs from Korea, Japan and America, and understands the technology as a skill. Consequently, in either study or actuality, it seems puts more emphasis on skills (moreover, the aspect of hardware). Second, in the aspect of curriculum and the cultivation of the genuine individuals, gives preponderance to science aspect, and the unclear distinction between the education technology and the computer science makes that the true character of educational technology is not clear. Third, when speaking of study fields and study methods, those of china is a little behind of the advanced nations of the educational engineering, Korea, America and so on. And in the range of study, China is following the international tendency but when it comes to the depth of study and quality is very far from perfect. In the aspect of study method, the theoretical study, design study and development study are occupying mostly, and it is hardly to see the existence about actual proof study, and in this aspect, it is quite different than that of Korea and America. And it is judged that it is related with the traditional educational ideology and the academic study tradition, the cultural air and the features of economical development of China.

The purpose of our study is to analyze the effect of socio-economic status on the diet pattern of Korean adults. Raw data from the fifth (2010-2012) Korea National Health and Nutrition Examination Survey (KNHANES) were used, and finally 11,700 adults were analyzed as subjects. Results in consideration of the socio-economic status of the subjects, a linear trend was observed in men in which the odds ratio of having lunch (p for trend=0.006) and dinner (p for trend=0.0317) decreased as the level of education went down. In diet frequency, a decreasing trend (p for trend=0.0328) was observed in which the odds ratio of having 3 meals a day reduced as the household income lowered. For women, a linear trend (p for trend=0.0012) was observed in which the frequency of dinner decreased as the level of education became lower. A falling trend in the rate of having 3 meals a day was also observed (p for trend=0.0135). Our study analyzed the characteristics of the diet patterns of individuals according to their socio-economic status with the purpose of suggesting guidelines for correcting. To prevent this, we will need education and awareness and public attention for the practice of correct eating habits.

The Korean Society for Engineering Education (KSEE) has been conducted scholarship meeting, workshop, and publicated academic journal, Engineering Education Research, since 1998. Kim Jin-soo analysed 'Engineering Education Research' on methods of research and contents. However, there are an in crease in quantity since then, it needed to analyse and arrange. This study analysed all 417 papers which were published from 1998 to 2012. The conclusion is as in the following. First, the number of collections published has been increasing up to 6 per year. 75.5% of the lead author's institution are universities, and Engineering Education Innovation Center researcher has been increasing steadily up to 8.9%. Research about Engineering Education Methods and Programs are being mostly studied. Apart from classified field in this, a study on the psychological characteristics of technology students are being steadily researched. In papers, the literature/development research method is used the most frequently (54.6%), the research study (39.9%) is the next and the experimental research method (5.5%) is followed by. Since 2006, study using the experimental research method is the growing lately. Second, characteristic of study between institution of lead author, a field of study, a number of study and methods of research by cross analyzing. The result is as in the following. In case of university and Engineering Education Innovation Center researcher studied much more about Engineering Education Methods and programs, research laboratory researcher tend to study about Engineering Educational Philosophy and Policy. Also, foreign researcher tend to introduce Engineering Education Example and Lecture. In case of university and foreign researcher used the literature/development research method frequently. Engineering Education Innovation Center and research laboratory and school researcher used the research study much more. There is no difference between a field of study and research methods. Finally, research strategies and new direction for improving the engineering education journal's papers at the section of discussion and suggestion were suggested.

This study analyzed research trends in the field of Practical Arts (Technology & Home Economics) education. From 958 articles published between 2010 and 2018 in the Journal of Korean Practical Arts Education (JKPAE), Journal of Korean Home Economics Education Association (JHEEA), and Korean Journal of Technology Education Association (KJTEA), 958 keywords were extracted and analyzed using NetMiner 4. When the general network structure was analyzed, keywords such as practical arts education, curriculum, textbook, home economics education, and students were high in the degree centrality and closeness centrality, and textbook, practical arts education, curriculum, student, home economics education, and invention were high in the node betweenness centrality. The cluster analysis showed that a four-cluster solution was most appropriate: cluster 1, technology and experiential learning activities; cluster 2, curriculum studies and practical problem; cluster 3, relationships; and cluster 4, creativity and character education. The three journals showed differences in the knowledge network structure: The topics of JKPAE and JKHEEA focused on general content knowledge and curriculum, while the topics of KJTEA were spread across invention and creativity education, and curriculum studies.

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.

The purpose of this study is to explore the research trend changes of convergence education since 2011 compared to the convergence education research that has been steadily continuing in science education. The trend in convergence education were investigated by comparing the number of publications, research subjects, research content, and topic linkages with previous studies, and using the network analysis method to check recent research trends. In the field of science education, the number of papers related to convergence education has been published more than 8.0% steadily, and it has been increasing since 2012, then decreasing again from 2015 and gradually increasing again from 2017. The subjects of study were high in elementary school students, while those in middle school, high school, and university students were low. While the number of in-service teachers increased, the number of pre-service teachers decreased, and the literature and public increased somewhat. In study content, effectiveness studies decreased, while development studies increased, and theoretical and perception studies appeared similar. In thematic linkage, the intra-science linkage was 23.9%, and the extra-science linkage was 76.1% and engineering/technology and art were high in extra-science linkage. In network analysis, elementary, science, STEAM, and program words have a high frequency of appearance and appear together with other words to lead the network. The educational implications of the research trend of convergence education will be more emphasized in the field of science education in the future, and in order to take root in the education field, research on secondary students should be more actively studied. In addition, it is necessary to move away from research on STEAM-centered program development and effects, and to increase research to establish the philosophical basis and theoretical of convergence education.
