Gongjae Yoon DuSeo(1668~1715), from Haenam in the late Joseon Dynasty, is a scholar-born painter who was active during King Sukjong. He is the person who created the foundation as a pioneer of realist paintings in the late Joseon period during the transition from the middle to the latter period. He was born in Namin's prestigious family, but he ended his career as part of a partisan fight and immersed himself in painting and learning. 18C, the beginning of the late Joseon Dynasty, was a period when Silhak emerged and the Jinkyung era opened with awareness of nationalism. At this time, by incorporating the Silhak thought into the art world, the real reformed aesthetic consciousness was demonstrated to pioneer common people's customs, the application of Western painting methods, the pursuit of realist techniques, and the introduction of Namjongmuninhwa. His view of painting, who thoroughly learned the old things and pursued change, must have both the form and spirit that he can achieve 'HwaDo' only when it has the science of 'learning and knowledge' and the technical elements of 'practice and quality' emphasized. He has worked in a variety of reconciliations. In particular, portrait paintings are characterized by ihyeongsasin's realistic expressions of aesthetics. His masterpiece, 「Self-portrait」, excels in extreme-realistic depiction and innovation in composition, and stands out with an unconventional experimentation spirit that expresses his mind and thoughts in a painting with a sense of resentment. His landscape paintings combine to express the form as it is and mental notions, and beautifully embodied Do as a form, thus achieving ihyeongmido, which reached the level of'joyfulness forgotten even the heart of joy'. On the other hand, the generalization of the common people using various common people's lives as the subject of an open-mindedness aimed at gaining the facts of ihyeongsajin, a passive protest against corrupt power and an expression of a spirit of love. Since then, his painting style has been passed down from generation to generation to his eldest son Yoon Deok-hee and his grandson Yoon Yong, leading the change and revival of calligraphy art in the late Joseon Dynasty.

The conventional TTS system consists of several modules, including text preprocessing, parsing analysis, grapheme-to-phoneme conversion, boundary analysis, prosody control, acoustic feature generation by acoustic model, and synthesized speech generation. But TTS system with deep learning is composed of Text2Mel process that generates spectrogram from text, and vocoder that synthesizes speech signals from spectrogram. In this paper, for the optimal Korean TTS system construction we apply Tacotron2 to Tex2Mel process, and as a vocoder we introduce the methods such as WaveNet, WaveRNN, and WaveGlow, and implement them to verify and compare their performance. Experimental results show that WaveNet has the highest MOS and the trained model is hundreds of megabytes in size, but the synthesis time is about 50 times the real time. WaveRNN shows MOS performance similar to that of WaveNet and the model size is several tens of megabytes, but this method also cannot be processed in real time. WaveGlow can handle real-time processing, but the model is several GB in size and MOS is the worst of the three vocoders. From the results of this study, the reference criteria for selecting the appropriate method according to the hardware environment in the field of applying the TTS system are presented in this paper.

We extracted the meaning of educational experience of the parents who moved to rural village for their children's education. While moving to the cities for the childen's education is general trend, moving to the rural village for the children's education is peculiar phenomenon. For the study, in-depth interviews were conducted with six parents who moved to rural village, and the statements were analyzed by the phenomenological analysis method of Colaizzi. As a result, thirty themes, eight theme clusters, and three meaning categories were extracted. Three categories which characterize the experience of parents who moved to rural village for their children are 'longing for nature-friendly life in rural area', 'positive experience of communication and empathy with neighbors', and 'children's happiness-centered education'. Eight theme clusters are 'dislike confined environment of an apartment', 'positive experience of childhood in the countryside', 'value direct and indirect experiences of variety', 'free and stimulating environment of countryside', 'experience of communicating and empathizing with neighbors','regret private education caused by parents' greed', 'value child centered education', 'yearn for the self-directed learning around character and art-physical abilities'. Based on the result, implications were discussed and follow-up studies were suggested.

School Violence is one of the most serious problems faced by Korean. As this serious problem becomes social issue in nation, many researchers have tried to find out the most effective solution of that problem and the reasons for why prevention of school violence are failed in such mind-hurting activities. The government and NGO proposed many the alternative to prevent the school violence. But the effectiveness of the alternatives art questionable. Last year Busan Metropolitan Police Agency and Busan Education Administration proposed new alternative in united cooperation which is namely Administration proposed new alternative in united cooperation which is namely 'school police' for school violence. School Police is composed of the retired teachers and ex-police officer, to do a prevention activity of school violence, which is expected to effectively curtail school violence in the assigned school. It is first networking try to prevent of school violence as a team of police and teachers in Korea. But the type of Korean school police system is different from American's school police, like as LASPD which is of sworn police officers. Korean school police is to employ a kind of school liaison officers. Though 'School Police System' got good reaction from students and citizen in Busan, It has some defects to be solved in future. So it hard to note that their efforts have been successful in curtailing the prevalence of school violence. In this paper, I present the new type of new 'Social Security Network Model' for school violence by repairing of 'korean school police system'. The problem of the school violence is not the problem of the school but the problem of society. In such viewpoints, It is important to plan a security network model which is participate in police officers, teachers, community and government. To prevent school violence effectively, I propose this new social security network model which based on theory of Community Oriented Policing, aggressive policing and CPTED technique.

This study aims to identify the trends in 'Aesthetic Science-Education' research through bibliographic analysis and provide future implications for research in this field. To this research, 100 studies were extracted using the search function of the Web of Science provided by Clarivate Analytics. Detailed bibliometrics was analyzed using the Bibliometrix package of the R program. As a result of the analysis, the average number of papers increased from 1993 to 2022, and academic journals in which related papers were published were evenly distributed locally. As a result of keyword analysis, papers with top citations, author collaboration networks, and literature co-citation networks, Aesthetic Science-Education could be classified as inducing aesthetic experience by integrating art in science education, and categories using 'formalist aesthetic' and 'emotional response'. The implications derived from this study are as follows: first, the aesthetic aspects of science should be actively studied to emphasize 'Agency' and 'Active Learning' in future science education. Second, it is necessary to develop a new approach to science education by further utilizing the 'formalist aesthetic' of science in science education. Third, the aesthetic aspect of science can change the perception of the Nature of Science of teachers, pre-service science teachers, and students. Fourth, it is necessary to discover implications for utilizing aesthetic aspects in science education through extensive research on the aesthetic aspects of science for teachers, students, and pre-service teachers. This study is meaningful because it provides an overview of the 'Aesthetic Science-Education' research to realize the above implications.
