  • The purpose of this study is to identify the main issues of international STEM education by synthesizing the findings in the field of global STEM education. The data in this study are the results of meta-analysis or systematic literature studies that reflect key issues of STEM education through the review of selection criteria and groups of experts. The following issues of STEM education were selected by conducting a qualitative meta-analysis of a total of 23 studies. First, STEM education is a global educational trend and has been studied in many countries such as the United States, Canada, Australia, Republic of Korea, and Turkey. Second, STEM education contributes positively to the improvement of students' cognitive, affective, psychomotor, and career domains. Third, STEM education has been studied with the use of various instructional tools and technologies. Furthermore, the growth of teachers' expertise in STEM education is one of the main factors for the implementation of successful STEM education. In addition, issues such as diversity, equity, and valid and reliable research design were discussed for the successful practice of STEM education. This study provides implications for the direction of convergence education and practical strategies in South Korea and gives suggestions for future research.

  • RFID is an emerging technology and rapidly applied to various industries due to its high-tech characteristic and convenience. Although RFID provides valuable benefits. it might also generate serious privacy problems. Previous studies show that privacy issues should be incorporated in developing RFID systems and more detailed privacy protection methods. However. they just provide basic concept, rough guideline. and simple architecture about RFID privacy protection. Industry needs more structured framework and detailed systematic process to incorporate privacy issues into the RFID system. The purpose of this paper is to develop a framework and detailed process design of RFID privacy protection issues in retail industries. A framework is developed based on individual sensitivity concept, RFID contents, and interface with EPC global standard. Case study is applied to validate the framework and it turns out to be useful. It is expected that the proposed framework and process design would provide more systematic guide lines to solving RFID privacy problems.

  • This paper deals with the global path planning problem for AUVs (autonomous underwater vehicles) in a tidal current field. The previous researches in the field were unsuccessful at simultaneously addressing the two issues of obstacle avoidance and tidal current-based optimization. The use of a genetic algorithm is proposed in this paper to move past this limitation and solve both issues at once. Simulation results showed that the genetic algorithm could be applied to generate an optimal path in the field of a tidal current with multiple obstacles.

  • The purpose of this study was to explore the elementary students' perceptions of Earth systems and environmental issues. A survey was conducted to determine the students' perceptions on the following aveas: (1) the concepts of certainty and tangibility, (2) self-reported knowledge level, (3) perceived danger level of selected eight Earth systems and environmental issues, and (4) their primary information source on these issues. Results indicated that ozone hole, acid rain, El $Ni\widetilde{n}o$, and global warming were identified by the students as uncertain and intangible issues. Perceived certainty and perceived tangibility were highly positively correlated with self-reported knowledge compared to other relationships. The results also showed that learning from school was the most frequent information source for environmental issues. The second most frequently used source of information was television among several mass media sources. It is hoped that this study contributes to understanding the elementary school students' perceptions toward the selected Earth systems and environmental issues.

  • The Korean Ministry of Environment and Daegu Metropolitan City are establishing the Korea Water Cluster, which will focus on promoting and escalating Korean water industries. The water industry, a future-oriented and promising business sector, is continuously growing each year worldwide, so the project is very timely. In reality, however, challenges still need to be addressed, such as accessibility, logistics systems, social infrastructures, and attracting good companies. For the Korea Water Cluster to be successful, those issues should be solved, but it is difficult to untangle the matters only with efforts of the Korean Ministry of Environment and Daegu Metropolitan City since some issues will require a great deal of both money and time. Therefore, it is important for the Korean federal government to administer support and finances for certain parts of the project, and for the Korean Ministry of Environment and Daegu Metropolitan City to take on other issues to ensure the Korea Water Cluster is successful long-term. The success of the Korea Water Cluster project will result in the Korea Water Cluster becoming a global hub for the future water industries.

  • The globalization of oriental medicine can be interpreted as the work of making its own contents able to be communicated among global heterogeneous cultural groups. In the field of oriental medical classics the work is to translate its classics into English and introduce them to researchers of oriental medicine in the world, which is essential in order to stimulate global academic communication in that the classics are the prototype as well as the source of oriental medical knowledge for thousands of years. Previous English translation studies have had limits in that terms used were not based on mutual agreement. Now "WHO International Standard Terminologies on Traditional Medicine in the Western Pacific Region(WHO-IST)" is the outcome of developing standard terminologies on oriental medicine contributed by researchers of Korea, China and Japan. The study aims to translate parts of "Classic of difficult issues(難經)" into English adopting "WHO-IST" hoping to set a model of translation study which can be communicated universally.

  • A proactive approach on environmental issues may be one of critical competitive factors for global business in near future. Especially, distribution systems are very related to the various environmental issues, including development of green products and packaging, selection of the transportation vehicles and pallets, design of retail stores and distribution facilities, participation for solving the local environmental problems, and so on. In order to approach the environmental issues on distribution systems, for the first time managers need to understand the strategic framework for green management and then, to find the key success factors of leading companies in this field. Finally, future directions of strategic green management on distribution systems are discussed and shared.

  • This study aims to utilize big data contents of news and social media for developing a corporate strategy of multinational enterprises and their global decision-making through the data mining technique, especially text mining. In this paper, the data of 2 news media (BBC and CNN) and 2 social media (Facebook and Twitter) were collected for the three global leading Korean companies (Samsung, Hyundai Motor Company, and LG) from April, 2018 to April, 2019. The findings of this paper have shown that traditional news media and also modern social media have become devastating tools to extract global trends or phenomena for businesses. Moreover, this presents that a company can adopt a two-track strategy through two different types of media by deriving the key issues or trends from news media channels and also grasping consumers' sentiments, preference or issues of interest such as battery or design from social media. In addition, analyzing the texts of those media and understanding the association rules greatly contribute to the comparison between two different types of media channels to see the difference. Lastly, this provides meaningful and valuable data empowered insights to find a future direction comprehensively and develop a global strategy for sustainability of business.
