  • Animal infectious diseases, such as avian influenza and foot and mouth disease, occur almost every year and cause huge economic and social damage to the country. In order to prevent this, the anti-quarantine authorities have tried various human and material endeavors, but the infectious diseases have continued to occur. Avian influenza is known to be developed in 1878 and it rose as a national issue due to its high lethality. Food and mouth disease is considered as most critical animal infectious disease internationally. In a nation where this disease has not been spread, food and mouth disease is recognized as economic disease or political disease because it restricts international trade by making it complex to import processed and non-processed live stock, and also quarantine is costly. In a society where whole nation is connected by zone of life, there is no way to prevent the spread of infectious disease fully. Hence, there is a need to be aware of occurrence of the disease and to take action before it is distributed. Epidemiological investigation on definite diagnosis target is implemented and measures are taken to prevent the spread of disease according to the investigation results, simultaneously with the confirmation of both human infectious disease and animal infectious disease. The foundation of epidemiological investigation is figuring out to where one has been, and whom he or she has met. In a data perspective, this can be defined as an action taken to predict the cause of disease outbreak, outbreak location, and future infection, by collecting and analyzing geographic data and relation data. Recently, an attempt has been made to develop a prediction model of infectious disease by using Big Data and deep learning technology, but there is no active research on model building studies and case reports. KT and the Ministry of Science and ICT have been carrying out big data projects since 2014 as part of national R &D projects to analyze and predict the route of livestock related vehicles. To prevent animal infectious diseases, the researchers first developed a prediction model based on a regression analysis using vehicle movement data. After that, more accurate prediction model was constructed using machine learning algorithms such as Logistic Regression, Lasso, Support Vector Machine and Random Forest. In particular, the prediction model for 2017 added the risk of diffusion to the facilities, and the performance of the model was improved by considering the hyper-parameters of the modeling in various ways. Confusion Matrix and ROC Curve show that the model constructed in 2017 is superior to the machine learning model. The difference between the2016 model and the 2017 model is that visiting information on facilities such as feed factory and slaughter house, and information on bird livestock, which was limited to chicken and duck but now expanded to goose and quail, has been used for analysis in the later model. In addition, an explanation of the results was added to help the authorities in making decisions and to establish a basis for persuading stakeholders in 2017. This study reports an animal infectious disease prevention system which is constructed on the basis of hazardous vehicle movement, farm and environment Big Data. The significance of this study is that it describes the evolution process of the prediction model using Big Data which is used in the field and the model is expected to be more complete if the form of viruses is put into consideration. This will contribute to data utilization and analysis model development in related field. In addition, we expect that the system constructed in this study will provide more preventive and effective prevention.

  • Those who were from Jaeincheon and Jaein line entertainers played great roles during transition period from traditional society to modern society, and even at present the dances of them are the representative traditional dances of Korea and the matrix of Korean originality. Nevertheless, Korea dance field has given little importance to these dances, but too much importance to Gibang dance in studying traditional dances, which causes the studies on Jaein line danced to be superficial or separate. Therefore, the aims of this article are to analyze the dances of Jaein line by Han Seong-jun, who was representative for the dances, and to appraise the historical value of them. Han Seong-jun(1874-1942) was the most influential dummer and dancer of his day in Japanese colonial times, and has been recognized as one of the masters of traditional dances. He established autonomy of traditional dances by reorganizing, collecting and stage-formalizing the dances, and systemized transmitting ways for various folk dances including a Buddhist dance, which made it possiblefor those dances to be traditional dances of Korea and the bases for creative dances. The values of Jaein line dances, which were transmitted through Han, are the following: First, the dances have been designated as national or regional intangible cultural assets, and, as the representative traditional arts, we proudly show them to the world. Second, the dances, as one of the genres of Korean dances, are the subjects of younger scholars' studies. Third, the dances become one of the representative examples of revivals of traditional dances, which tend to be extinct during modernization times, and contribute to establishing national identity and subjectivity. In addition, they contribute to discovering and transmitting other traditional dances. Fourth, the dances enable many dancers to make association, that is, Association for Preservation of Traditional Dances,for the transmitting the dances, and to distribute the dances and get many dancers to transmit the dances. Furthermore, as new performance repertories, they give another pleasure to the audience. In addition to the above, as a base for expansion of Korean creative dances, Han's dances have other values such as the following: First, in searching for a new methodology for creation, he played an important role in rediscovering the foundation in the tradition, and tried to discover nationalidentity by employing the traditional dances for expression of theme. Second, he contributed to drastically dissolving the genres by expanding the gesture language from motion factors of traditional dances, which can be compared to the modern dance. Third, he tried new challenging approaches to re-create the tradition, and contributed to pursuing the simple elements of our traditional dances as traditional aesthetics. While the dances of Jaein line have such values as the above, there are also some problems around the dances, such as the confusion in the process of transmission resulted from different transmission forms and transmitters, which we must no longer leave as it is. Furthermore, it is urgent that the rest of Jaein line dances be recovered and designated as intangible cultural assets for the sound transmission of the traditional dances.
