In this study, we developed elementary science education modules for facilitating students' understanding of the connected nature of Science-Technology-Society. For these modules, we particularly used news articles to make connections among science, technology, and society. We set up the development criteria as followings: connecting science-technology-society, aligning with national science curriculum, respecting students' interest, and appropriating the difficulty levels in terms and concepts. We also studied 4th grade students' perception of using these modules in science lessons. Most students perceived that using the modules in their science classes helped them link science-technology-society intimately and enhance their interest and motivation, as well as their self-esteem for studying science.

Educational technology (ET) and learning sciences (LS) are two related disciplines that have shared interests in studying technologies for advancing human learning. This study conducted a content analysis of articles published in authoritative academic journals, Educational Technology Research and Development (ETR&D) and Journal of the Learning Sciences (JLS) from 2003 to 2012. By selecting and examining 93 issues with 429 articles during this decade with three analytical frameworks, the purpose of this study is to determine research trends precisely and create a scientific communication and theoretical connections for these two disciplines. The illustrated results indicate the dialogue between these two communities has begun yet accompanied by some certain limitations, whereas, they still need be more cooperative and communicational to move towards further integration, so as to contribute to promoting progressive education, learning theory and practice.

This study is to respond to the urgent demands of both society and times on public schools in regards to training an educated person who can cope with the financial environment of this diversified modern society. Therefore, this study will explain the concept of Financial Consumer Education and its trends of several other countries. By focusing on the current state of Korean Financial Consumer Education, it will call attention to the needs of introducing Financial Consumer Education to the school curriculum in order to educate students about finance systematically. To support our viewpoint, this paper analyzed and organized the materials concerning Financial Consumer Education in two curricula (2007 and 2011 Revised National Curriculum), and in a Practical Arts (Technology Home Economics) textbook of the 2007 revised version. Hence, the purpose of this study is to explore the desired direction and revitalization of Financial Consumer Education by analyzing the existing curricula. Even though the content of finance education begun from one of the subcategories of consumer education called 'Financial Management,'the number of research about financial education through public education has been increased in response to the social and academic consensus. Therefore, we suggest the re-conceptualization of consumer education for financial education is necessary. Therefore, this paper suggests that Financial Consumer education in a Practical Arts (Technology Home Economics) should not be regarded as only one of the components of Consumer Education. Instead, by raising it to the status of Financial Customer Education, it is required to teach the learners to improve their personal financial management skill as well as to help them achieve financial knowledge, skill, and attitude as financial consumer.

In plant-pathogen interactions, Magnaporthe oryzae causes blast disease on more than 50 species of 14 monocot plants, including important crops such as rice, millet, and most 15 recently wheat. M. oryzae is a model fungus for studying plant-microbe interaction, and the main source for fungal pathogenesis in the field. Here we report that MoJMJD6 is required for conidium germination and appressorium formation in M. oryzae. We obtained MoJMJD6 mutants (ΔMojmjd6) using a target gene replacement strategy. The MoJMD6 deletion mutants were delayed for conidium germination, glycogen, and lipid droplets utilization and consequently had decreased virulence. In the ΔMojmjd6 null mutants, global histone methyltransferase modifications (H3K4me3, H3K9me3, H3K27me3, and H3K36me2/3) of the genome were unaffected. Taken together, our results indicated that MoJMJD6 function as a nuclear protein which plays an important role in conidium germination and appressorium formation in the M. oryzae. Our work provides insights into MoJMJD6-mediated regulation in the early stage of pathogenesis in plant fungi.

C-SiC films with different content of SiC on stainless steel substrate were prepared with ion beam mixing. It was found that hydrogen concentrations in C-SiC coatings was higher than that in stainless steel after H$\^$+/ ion implantation followed by thermal annealing. Infrared (IR) transmission measurement was used to study the mechanism of hydrogen retention by C-SiC films. The vibrational features in the range between 400 and 3200 cm$\^$-1/ in IR transmission spectra show the Si-CH$_3$, Si-CH$_2$, Si-H, CH$_2$and CH$_3$bonds, which are responsible for retaining hydrogen.

According to the rapid change of the modern society, science & technology influences the society significantly. Thus, Korean education, especially the science education must be reviewed in the terms of that, the purpose of this article is to introduce social, environmental context's science education-STS education. STS education is to arise the ability of the democratic decision-making & participating in a discussion. The areas of this are knowledge, process, creativity, attitude, application. Also there are social issues approach & the social studies of science approach in the STS education. The social issues approach is the predominant approach to STS education; the social studies of science approach is often found in the form of goals & objectives for STS education. In order to introduce STS education to Korean science education,this author suggests the following; 1. The relation between science & society in science education must be emphasized more. 2. The study and development of STS education appropriate for Korean society must be preceded. 3. The new course about STS and technical education in the level of college must be developed.

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.
