The main purposes of this study were (a) to analyze the research trend of educational use of tangible technology, (b) to identify tangible learning mechanisms, and potential benefits of learning with tangible technology, and (c) to provide references and future research directions. We conducted a systematic literature review to search for academic papers published in recent five years (from 2013 to 2017) in the major databases. Forty papers were coded and analyzed by the established coding framework in four dimensions: (a) basic publication information, (b) learning context, (c) learning mechanism, and (d) learning benefits. Overall, the results show that tangible technology has been used more for young learners in the kindergarten and primary school contexts mainly for science learning, to achieve both cognitive and affective learning outcomes, by coupling tangible objects with tabletops and desktop computers. From the synthesis of the review findings, this study suggests that the affordances of tangible technology useful for learning include embodied interaction, physical manipulations, and the physical-digital representational mapping. With such technical affordances, tangible technologies have the great potential in three particular areas in education: (a) learning spatial relationships, (b) making the invisible visible, and (c) reinforcing abstract concepts through the correspondence of representations. In conclusion, we suggest some areas for future research endeavors.

Background: As the public interest in chemical substances found in daily life has increased, environmental health education content has been developed and related studies have been conducted. However, there is still insufficient research on methodologies for environmental health education. Objectives: This study aimed to explore risk communication strategies by focusing on N-nitrosamines in rubber balloons. Methods: In this study, two different health messages were composed: a gain-framed message emphasizing the advantages of practicing the health behavior and a loss-framed message emphasizing the negative consequences of not practicing the health behavior. The effect of the message containing risk information was evaluated by measuring the health beliefs and health behavior potential for female caregivers. As the Environmental Health Act defines a child as "a person under the age of 13," a total of 131 women with children under the age of 13 were studied. Results: The age, awareness, and interest of the participants in the gain frame group and these in the loss frame group were similar. In terms of message framing effect, the gain-framed message was more effective in terms of health belief and potential health behavior than was the loss-framed message. As a result of an independent t-test, among the six variables of health belief model the message effect was statistically significant at the level of p<0.05 in three variables: perceived severity (t=2.287, df=129, p=0.024), self-efficacy (t=2.123, df=129, p=0.036), and health behavior potential (t=2.094, df=129, p=0.038). Conclusions: This study presented a direction for effective environmental health education by studying the effects of risk communication messages based on scientific evidence. It is necessary to extend the scope of environmental health education research by expanding research into various household products.

Through the careful examination of seminal papers, this study carefully explores the integration of IVR in high school mathematics education. It highlights significant contributions of IVR in improving students' computational proficiency, problem-solving skills, and spatial visualization abilities. These enhancements are crucial for developing a robust mathematical understanding and aptitude, positioning students for success in an increasingly technology-driven educational landscape. This review emphasizes the pivotal role of teachers in facilitating IVR-based learning experiences. It points to the necessity for comprehensive teacher training and professional development to fully harness the educational potential of IVR technologies. Equipping educators with the right tools and knowledge is essential for maximizing the effectiveness of this innovative teaching approach. The findings also indicate that while IVR holds promising prospects for enriching mathematics education, more research is needed to elaborate on instructional integration approaches that effectively overcome existing barriers. This includes technological limitations, access issues, and the need for curriculum adjustments to accommodate new teaching methods. In conclusion, this review calls for continued exploration into the effective use of IVR in educational settings, aiming to inform future practices and contribute to the evolving landscape of educational technology.

Marine ecosystems are often characterized by a high biological diversity, and it corresponds to a high chemical diversity. Up to present, more than 20,000 new bioactive substances have been isolated from marine organisms, where considerable numbers of these naturally occurring derivatives are developed as potential candidates for pharmaceutical application. In this process, screening of natural products from marine organisms that could potentially inhibit the expression of metalloproteinases has gained a huge popularity. Cancer is considered as one of the deadliest diseases in the medical field. Matrix metalloproteinase (MMPs) can degrade extracellular matrix (ECM) components and play important roles in a variety of biological and pathological processes. Matrix metalloproteinase inhibitors (MMPIs) have been identified as potential therapeutic candidates for metastasis, arthritis, chronic inflammation and wrinkle formation.

Purpose: this study is aimed at assessing the contribution of education and innovation to the economic growth of Kazakhstan, the correlation between them is checked based on two levels on a national scale and a regional scale. Based on the literature review, it was revealed that in the vastness of the scientific community, there are many views concerning the influence of educational and innovative factors on economic growth. Research design, data and methodology: the research methodology is divided into two levels, at the first level, a correlation analysis is carried out between key factors and the economic growth of the country (GDP), at the second level, the same factors are analyzed, but the impact on the economic growth of the region (GRP) is estimated. Statistical data on educational and innovation potential is taken from the Bureau of National Statistics for the period 2003-2021. Results: in this study, it was revealed that the economic development of regions could be influenced by such indicators that cannot affect the entire state in aggregate and vice versa. In addition, the correlation analysis results showed that investments in innovations affect economic growth at the country and the regional level. Conclusions: based on the results of the assessment of educational and innovative potential, policy recommendations and further research in this area were proposed.

Background: To identify and avoid predators, amphibians rely on chemical cues. Onychodactylus koreanus undergo two to three years of the larval stage in mountainous streams, where they encounter various predators. We aimed to identify the potential predators of O. koreanus larvae based on their antipredator responses to predator odors. Additionally, we examined whether the response was innate or can be strengthened by predator olfactory learning. Results: In Experiment 1, O. koreanus larvae exhibited a substantial antipredator response to Chinese minnow (Rhynchocypris oxycephalus) odor but not to Korean freshwater crayfish (Cambaroides similis) odor. In Experiment 2, O. koreanus larvae, who did not previously expose to R. oxycephalus odor, demonstrated a substantial antipredator response to it. Experiment 3 indicated that predator olfactory learning of R. oxycephalus did not enhance the antipredator response of the larvae. Conclusions: Rhynchocypris oxycephalus could prey on O. koreanus larvae, whose antipredator response to R. oxycephalus odor is innate and not enhanced by olfactory learning. Further investigation into the olfactory system of this species may provide insights into the life cycle of O. koreanus, uncovering hidden underground breeding sites and unknown breeding periods.

In this study, Life Cycle Assessment(LCA) was applied to the production processes of waste cooking oil recycling products. Recycling products as defined in the Law of Saving of Resources and Recycling Promotion are biodiesel and soap. Weighting result of biodiesel production process showed that the most significant impact potential was abiotic resource depletion(84.17%) followed by global warming(13.93%). In the case of the soap, the most significant impact potential was also abiotic resource depletion(58.59%) followed by global warming(33.71%). In terms of the whole system of the biodiesel production process, methanol showed the largest environmental impact potential(87.35%). While in the case of the soap, sodium chloride showed the largest environmental impact potential(99.99%). This study suggests that there should be improvement of the methanol recovery system in the biodiesel production process and also appropriate use of the major environmental impact materials in both processes.

The purposes of this study is to verify additional demand of students for secondary vocational education, and draw political implications. To meet the purposes, firstly we analyzed current policies on the secondary vocational education. Second, we divided additional demand of students for secondary vocational education into practical and potential demand. Practical demand by students who would like to take further vocational education in secondary education system includes students who hoped to enter vocational high school however they failed to go, the first or second year students who transferred from general high school to vocational high school, and the third year students who are in general high school would like to take commissioned vocational courses. Potential demand is an additional demand for secondary vocational education in a society perspective. This includes a student who downgraded employment even though they entered college or university after graduated general high-school. Comparing the result of this study with the entrance quota of vocational high-school, additional demand of students for secondary vocational education showed that accounted for 61.2 percent of the entrance quota year 2015. Specifically, potential demand accounts for 31.7 percent of the entrance quota for vocational high school and practical demand accounts for 29.5 percent.

The purpose of this study is to analyze the influence of digital textbook use for potential risk group of internet addiction and average group. For this, I selected two samples. One was a group to use digital textbook at school, the other was a group not to use that. Then each potential risk group of internet addiction were sort out in two groups by a test of internet addiction. I firstly compared a average user group and a potential risk group of internet addiction in group to use digital textbook. Also, I too did that in group not to use digital textbook. Then I analyzed the relevance of using digital textbook and internet addiction. As a result, I found that using digital textbook have not the relevance with internet addiction. But in this paper, I proposed a way to teach ICT ethical training before students use the digital textbook, because most of potential risk students of internet addiction tend to think they was influenced by digital textbook.
