A cylindrical microlens (CML) has been widely used as an optical element for organic light-emitting diodes (OLEDs), light diffusers, image sensors, 3D imaging, etc. To fabricate high-performance optoelectronic devices, the CML with high aspect ratio is demanded. In this work, we report on facile solution-based processes (i.e., slot-die and needle coatings) to fabricate the CML using poly(methyl methacrylate) (PMMA). It is found that compared with needle coating, slot-die coating provides the CML with lower aspect ratio due to the wide spread of solution along the hydrophilic head lip. Although needle coating provides the CML with high aspect ratio, it requires a high precision needle array module. To demonstrate that the aspect ratio of CML can be enhanced using slot-die coating, we have varied the molecular weight of PMMA. We can achieve the CML with higher aspect ratio using PMMA with lower molecular weight at a fixed viscosity because of the higher concentration of PMMA solute in the solution. We have also shown that the aspect ratio of CML can be further boosted by coating it repeatedly. With this scheme, we have fabricated the CML with the width of 252 ㎛ and the thickness of 5.95 ㎛ (aspect ratio=0.024). To visualize its light diffusion property, we have irradiated a laser beam to the CML and observed that the laser beam spreads widely in the vertical direction of the CML.

Recently, due to a decrease in the school age population, it is expected that there will be great difficulties in recruiting students. The dropout rate for the last three years of four-year universities nationwide announced in www.academyinfo.go.kr has been continuously increasing at 4.1% (2016), 4.3% (2017), and 4.6% (2018). It has emerged as the biggest issue facing the university. In this study, through a large-scale empirical study at H University, an analysis of the dropout intention of college students and educational factors affecting their intentions were derived. First, as a result of analyzing the intention to drop out, the dropout intention of students in the engineering department was higher than in the humanities, and it was higher in the upper grades. Students from specialized high schools were higher than general high schools, and the students who raised the tuition fees were higher than those who were not. As a result of factor analysis on dropout intention, it was analyzed that class difficulty, major satisfaction, parent satisfaction, internationalization satisfaction, and college education performance satisfaction had a significant effect on dropout intention.

Considerable interest has been directed toward utilizing virtual environment-based simulations for teacher education which provide authentic experience of classroom environment and repetitive training. Emotional Interaction should be considered for more advanced simulation learning performance. Since emotion is important factors in creative thinking, inspiration, concentration, and learning motivation, identifying learners' emotional interactions and applying these results to teaching simulation is essential activities. In this context, this study aims to identify the objective data for the empathetic response through the movement of the learner's EEG (Electroencephalogram) and eye-tracking, and to provide clues for designing emotional teaching simulation. The results of this study indicated that intended empathetic response was provided and in terms of valence (positive and negative) states and situational interest played an important role in determining areas of interest. The results of this study are expected to provide guidelines for the design of emotional interactions in simulations for teacher education as follow; (a) the development of avatars capable of expressing sophisticated emotions and (b) the development of scenarios suitable for situations that cause emotional reactions.

Thanks to the competition of AlphaGo and Sedol Lee, machine learning has received world-wide attention and huge investments. The performance improvement of computing devices greatly contributed to big data processing and the development of neural networks. Artificial intelligence not only imitates human beings in many fields, but also seems to be better than human capabilities. Although humans' creation is still considered to be better and higher, several artificial intelligences continue to challenge human creativity. The quality of some creative outcomes by AI is as good as the real ones produced by human beings. Sometimes they are not distinguishable, because the neural network has the competence to learn the common features contained in big data and copy them. In order to confirm whether artificial intelligence can express the inherent characteristics of different arts, this paper proposes a new neural network model called Humming. It is an experimental model that combines vgg16, which extracts image features, and DeepJ's architecture, which excels in creating various genres of music. A dataset produced by our experiment shows meaningful and valid results. Different results, however, are produced when the amount of data is increased. The neural network produced a similar pattern of music even though it was a different classification of images, which was not what we were aiming for. However, these new attempts may have explicit significance as a starting point for feature transfer that will be further studied.

There are many eyes that recognize Korean traditional performing arts as low, unorganized, and not a play. However, there is clear in the Korean traditional performing arts have a story with a perfect narrative structure. From the Miyal which accepts the Western tragedy theory to the Gangneung Gwanno Mast drama which contains the love story of the comedy, many Korean traditional performances contain the elements of narrative even though the contents are very simple. It is true that there are very few things with perfect narrative structure among the Korean traditional performance that has been passed down so far. It is the responsibility of the researchers to unearth and restore these, and it is the task of the creative artists to create new ones according to contemporary philosophy. If these two fields communicate smoothly, we will be able to look at the future of our traditional performing arts more brightly than now. As a result, it will also be a challenge to solve the problem of letting Korean traditional plays penetrate ing the world market.

The Korean innovation ecosystem has evolved from a catch up stage to a creative leader stage where government's role in creating a private sector driven, healthy and dynamic ecosystem is important. Korea's innovation ecosystem shows a stagnation of innovation performance and a lack of linkage activities within the national innovation ecosystem and in global cooperation, despite the dramatic advancement and expansion of the ecosystem. A next-generation innovation ecosystem model is required to create a future-oriented innovation ecosystem. The next generation innovation ecosystem was prepared on the basis of the framework, which has 6 elements among which inter-firm network is the the micro-foundation of the ecosystem. On the basis of the framework, assuming that the next generation innovation ecosystem is the evolved existing ecosystem, responsive the discontinuous change in market and technology, which is private sector driven healthy and dynamic ecosystem, the next generation innovation ecosystem model was created. The concrete details on the direction of the policy entities responsible for building the ecosystem was presented, and the contribution of this study was discussed.

This study examines the concepts and characteristics of Interculturalism and extracts artistic expressions of intercultural characteristics shown in Nouvelle Danse and Non-Danse, which were the birthplace of the contemporary dance flow in Europe. The discussion and composition of these dances will be analyzed from an intercultural perspective by selecting three works by each choreographer representing Nouvelle Danse and Non- Danse. In doing so, we would like to examine what creative acceptance was achieved based on the values and understanding in the clash and encounter between different cultures in art. Dance and interculturalism emphasize exchanges and encounters between one's own culture and other cultures. In addition, it has the potential to contribute to dance studies through the humanistic perspective of dance, as it also contains issues about diversity and identity due to exchange between cultures at the center of globalization. Therefore, the purpose of the study is to read the artistic expressions of choreographers in Nouvelle d'Anse and Non-d'Anse through intercultural understanding with an in-depth understanding and to interpret them by adding multi-layered time to the study.

There is a growing interest in the technology transfer and commercialization both at home and abroad. Accordingly, this study looked at the concept of technology transfer and commercialization, identified the factors that should be taken into account in order to facilitate technology transfer and commercialization, and then performed a empirical analysis. As for the conventional technology transfer and commercialization, there was a tendency to limit its scope to the exploration, transfer and commercialization of technology itself. Here in this research, technology transfer and commercialization is defined the category to expand as various activities implemented in order to make sure that intellectual properties such as intangible technological developments, know-how, and knowledge are transferred between the relevant parties through a contract or negotiation, and the party to which the transfer is made can then further develop and exploit the technology into tangible products and other activities to obtain economic benefit out of that. In addition, the findings of the positive analysis of technology transfer and commercialization revealed that the focus of facilitating technology transfer has been on the technology itself, its management and securing efficiency of the systems and institutions involved in the technology transfer and commercialization. So there was lack of recognition as to the importance of financial support given to the phase of technology commercialization. This indicates that when it comes to the technology transfer and commercialization, quantitative performance has been the focus of interest such as patent application, registration, number of technology transfers, royalty, etc. So there was not enough understanding as to the issues of starting up a business, creating quality jobs through technology transfer and commercialization, which are directly related to the realization of the creative economy. In this regard, this research is expected to be used for the development for the future policies to boost technology transfer and commercialization as it suggests not only simply ensuring quantitative performance but also necessary to create the environment for the creation of the stable ecosystem for the parties involved in the technology transfer and commercialization and then to build circumstances in which creative economy can be realized.
