Since 2019, research on microplastics has been actively conducted around the world, so analyzing the differences between domestic and foreign microplastics research can be a milestone in establishing the direction of domestic research. In this study, microplastic papers from KCI and WoS were extracted and the differences between domestic and foreign studies were analyzed using a network analysis methodology based on big data such as author keyword co-occurrence word analysis, thesis co-citation analysis, and author co-citation analysis. As a result of the analysis, the analysis of the research topic confirmed that studies that could affect the human body and the treatment of microplastics in daily life were additionally needed in Korea. In the analysis of the depth of thesis citation that examines the quality of research, it was found that Korea was still insufficient at 2.25 overseas and 1.39 in Korea. In the analysis of the composition of the joint research front, where various researchers participate and share information, 3 out of 22 clusters in Korea are Star type. In the case of overseas, all 19 clusters have a mesh structure, so it was confirmed that information flow and sharing were insufficient in specific research fields in Korea. These research results confirmed the need to expand the research topic of microplastics, improve the quality of research, and improve the research promotion system in which various researchers participate. In addition, if the automation program is developed based on topic modeling, it will be possible to build a system capable of real-time analysis.

This study aimed at understanding the characteristics of interactive discourses between docents and visitors in natural history museums. Two docents participated in this study. One worked in Seodaemoon Natural History Museum and the other in Gwacheon National Science Museum. To analyze the characteristics of interactive discourses, especially understanding the mediation of visitors' learning, Pedagogic Discourse Analysis method was adopted. The results show two contrasting types of interactive discourses, Encouraging Visitors' Meaningful Participation (EVMP) and Encouraging Visitors' Simple Participation (EVSP). In the EVMP discourse, structural cohesion is strong in thematic flow and information flow. Docent and visitors share the role of information provider and "Themes" are developed through the interactions between the docent and the visitors. On the contrary, in the EVSP discourse, structural cohesions are weak. Even though the visitors participate in the discourse, their discourse scarcely contribute to develop "Themes" in the discourse. Most of the information is developed and expanded by the docent. These results helped us to suggest that docents have to understand and use visitors' prior knowledge as a discourse "Theme." It is also suggested that docents need to have not only the competent content knowledge about exhibitions but also the capability to lead discourses that allow the visitors to participate meaningfully during the education processes.

This study analyzes difficulties of enterprise activities in Chinese construction market by surveys on early entrants and interviews with experts. This study also suggests future strategy to enter the market by using inducement coefficient model. Korean construction companies in China are under heavy pressure to maintain requirement of licenses, despite recent deregulation. They are in dire predicament for market entry due to the Foreign Direct Investment System. It is almost impossible to participate in public projects and also it is not easy to do PPP projects. Therefore, Korean government should make more efforts to solve those issues through negotiations in FTA and GPA. For future expansion in Chinese construction market, it is highly recommended to boost cooperation models between Korea and China according to the empirical results of inducement coefficient model. Korean companies should collaborate with Chinese companies in some fields: smart city, environment and water treatment. Also, Korean government should support Korean companies by diplomatic means such as requesting for further opening of China's market. In GPA or GATS negotiation, Korean government should ask Chinese government that Korean companies can obtain order independently (without joint venture with Chinese companies) in China. Lastly, Korean construction companies should participate in construction projects ordered by international organizations such as ADB, AIIB.

This study deals with the credibility of citizens when investing in uncertain project companies, as well as the Social Performance Compensation Project (SIB) and the IT sharing economy. This allows the convergence of the three sectors to address investment inequalities in economic effectiveness and social security. Activates the model of the overall Social Impact Bond (SIB) process that successfully activates the exchange of information. The empirical presentation of the operations and techniques for social IT service finance examines how the innovation ecosystem can be created with social performance and reward projects. The analysis shows that small sharing institutions or citizens can participate directly to create the ability to connect with private investors, identify the possibility of recognizing non-shared barriers to participation, and show the great impact of citizen trust in IT sharing projects in uncertain areas. As a result, for the sake of social sharing and IT cooperation promoted by the City of Seoul, before the project has the ability to design directly, it will be responsible for reliability and safety in the planning of the project. Therefore, non-shared citizens can also participate in the platform that has been effectively constructed and created.

This study proposed the ubiquitous learning system by finding the difficulties which students have in learning the course of science and analyzing the current learning applications that are used commercially. Through case studies, we found 4 problems. First, the request of long learning time by most of the existing video-based learning applications. Second, it is impossible to know their level of learning due to the lack of open learning contents. Third, it is difficult for learners to participate in interactive learning. Fourth, there are educational contents without considerations on the level of learners. To refine the difficulties due to these problems, we designed and implemented a new ubiquitous learning system which applies the small learning contents for short-term learning, open learning system and enhanced hierarchical learning contents. The system was implemented based on Android. It provides learners with useful science education. We conducted a questionnaire for third grade middle school students in order to show that the proposed system has a good educational effects. The questionnaire asks for the differences between the proposed ubiquitous learning system and the existing learning application. We concluded that the proposed system is better than the existing application by using t-test for improvement of learning effects using feedback with which students participate in interactive learning but not in unidirectional learning, and share the learning result.

Since the Web 2.0 generation, the average user is more than just enjoying the various media contents; they start to create contents, and those contents have had a huge value and great influence in recent days. The reason for the increase of users who tend to create contents is due to popularization of web based applications. Previous applications were only for the skilled person; however, new web based applications involve the average person and give him a new level of user enjoyment by allowing him to create easily with simple operations. In this paper, through analysing previous animation-creating applications which could not spread widely compared to other contents, we suggest the outline for developing a web based animation-creating application which can help the user to easily create animation contents. We have looked around at how various other contents-making applications have been changed to help the user to be able to participate in creating contents, and we suggest how animation-creating applications can be changed and developed from this analysis. We expect the conclusion of this paper to stimulate to development acting 3D animation-creating applications corresponding to the web 2.0 features - open, share, cooperate, participate. In result, users can enjoy creating the animation more actively; at the same time, we hope to help the development of the new applications which correlate to memedia generation.

As the business competition between firms is getting intense, one of the sources of competitive advantage is effectively and efficiently to create, share, and apply information/knowledge among employees. Most of the firms which conduct knowledge management are operating a Community of Practice(CoP) in order to create, share and utilize this kind of information/knowledge resource. Recently, the CoP is getting out of its informal and spontaneous manner and is beginning to be led by the top management, receiving official support, in order to achieve the organization's strategic goals. However, the corporation's strategic operation of the CoP is not only against its original characteristics but also hampers the spontaneity of its participants. Every participant has different motivation to participate and different preference for reward type. This study, with the survey of 114 respondents, found that intrinsic motivation as well as extrinsic motivation significantly affect the motivation-reward fitness. Also, the motivation-reward fit was found to influence CoP commitment which ultimately leads to knowledge sharing activity in the CoP context. This research will help knowledge management companies to figure out how the two things of participants' motivation and their reward types can fit together, and how such fitness ultimately affects the participants' commitment and their knowledge sharing activities.

Medical humanities has become a third area of medical education following basic and clinical medicine. Also, in the national evaluation of medical schools, medical humanities education is an important factor. However, there are many difficulties in teaching medical humanities in medical schools. First, it is still an unfamiliar education area to medical schools and professors. Second, still, there is no consensus on the definition and contents of this education. Third, it is usually very difficult to find professors who have interest and the ability to teach medical humanities. Fourth, even medical students do not understand why they should study medical humanities and sometimes do not eagerly participate in class. This paper suggests some solutions for these problems. First, medical humanities need to be divided into sections according to how easily the contents can be accepted by existing medical education system and apply these sections in the introduction of this education gradually and in stage. One example of the division can be as follows: Group 1) medical ethics and medical law which can be most easily accepted. Group 2) medical communication skills which can be relatively easily accepted. Group 3) medical history and medical professionalism which is relatively difficult to accept, and Group 4) medical philosophy, medicine and music, medicine and literature, medicine and art, medicine and religion, etc. which is the most difficult to accept. In this paper, four things are suggested. Second, divide the contents into mendatory courses and elective courses. Third, allocate the contents throughout the four years from the first year though the fourth year according to the spiral curriculum model. This paper reports some new ideas and methods for medical humanities education. First, to stimulate students' participation, several methods were applied in a large size lecture and student projects. Second, the emphasis of writing in class and evaluation were discussed. Third, the provision of hands on experience is more emphasized than lectures. Fourth, inviting some doctors who work in non-medical areas such as journalism, pharmaceutical industry, etc is suggested. Trial and error is inevitable in this education, but it is essential in molding a good doctor, so medical professors who are interested or in charge of this medical humanities education need to share their ideas and experiences.

The purpose of this study is to analyze the actual condition of the already established rural theme park, draw the weak and strong points, and come up with an efficient performance plan for Changwon Persimmon Theme Park through the benchmarking of the best overseas case. According to the analysis, it is necessary to introduce a facility and a program for family customers as a plan for promoting Changwon Persimmon Theme Park. It is required to secure safety through public operation and management, improve scalability of the facility through the establishment of multi-functional complex facility, and come up with a plan for operating a special program associated with local resources. Therefore, this study drew three activation factors: the establishment of operation and management system, the development of operation contents by facility, and the establishment of operation in each area. First, to establish the operation and management system, it is necessary to classify the organization of the theme park into the operation business area and into operation & management area by job function. Secondly, it is necessary to establish a special program in consideration of space and facility, suggest a differentiated plan for operation contents, and create a facility operation plan and program for Changwon Persimmon Theme Park. Lastly, to operate and manage Changwon Persimmon Theme Park smoothly, it is necessary to set the theme park space as open collaboration space which the local residents can share and participate in by avoiding the conventional administration-based business performance and operation. This study suggested the plan for establishing an operation and management system for Changwon Persimmon Theme Park and its operation, the establishment of a special program, a business performance strategy, and the use of internal and external spaces of the theme park.

As recently too many local museums have been built in the whole country, most of them cannot attract enough spectators. In order to resolve this problem, it is needed for local museums to differentiate their spaces and programs related to their exhibition. Thus, the purpose of this study was to analyze the characteristics of spaces and programs of local museums from the perspective of spatial marketing to activate them, and contribute to development of local cultures. This study targeted historical public museums located in Seoul and Incheon. Through preceding research, an analysis frame was established based on the keywords related to spatial marketing, and then the characteristics of spaces and programs of local museums were analyzed based on the frame. The study results are as follows. 1) Access convenience refers to openness that public museums located in Seoul and Incheon can embrace accessible locations, points of interest, and convenient facilities easily recognized by pedestrians. 2) Symbolic formativeness is to express symbolic historical contents in the museum lobby or exhibition to show the identity of local museums. 3) Visibility is needed for direct guidance signs or spaces to let spectators know directions and locations. 4) Public concern is for spectators and local residents to participate in local museums to share and utilize their partial spaces. 5) Interactivity is to induce activation of local museums by utilizing experience exhibition contents and having spectators directly contact exhibits. 6) Interest is related to cultural festival programs of exhibition to arouse spectators' and local residents' curiosity. 7) Participation is to activate spaces and spectators by providing educational programs. 8) Usefulness is to induce spectators' interest in local museums by providing historical, social, and cultural information. These results are expected to be used as baseline data to suggest a new direction for activation of local museums from the perspective of spatial marketing.
