Recently, the size of online texts and textual information is increasing explosively, and the automated classification has a great potential for handling data such as news materials and images. Text classification system is based on supervised learning which needs laborous work by human expert. The main goal of this paper is to reduce the manual intervention, required for the task. The other goal is to increase accuracy to be high. Most of the documents have high complexity in contents and the high similarities in their described style. So, the classification results are not satisfactory. This paper shows the implementation of classification system based on ETOM+RPost algorithm and classification progress using SPAM data. In experiments, we verified our system with right-training documents and wrong-training documents. The experimental results show that our system has high accuracy and stability in all situation as 16% improvement in accuracy.

To complete an image, it is needed to go through the process to capture the actual actor's motion and compose it with virtual environment. Due to the excessive cost for production or lack of post-processing technology, however, it is mostly conducted by manual labor. The actor plays his role depending on his own imagination at the virtual chromakey studio, and at that time, he has to move considering the possible collision with or reaction to an object that does not exist. And in the process of composition applying CG, when the actor's motion does not go with the virtual environment, the original image may have to be discarded and it is necessary to remake the film. The current study suggested and realized depth-based real-time 3D virtual image composition system to reduce the ratio of remaking the film, shorten the production time, and lower the production cost. As it is possible to figure out the mutual collision or reaction by composing the virtual background, 3D model, and the actual actor in real time at the site of filming, the actor's wrong position or acting can be corrected right there instantly.

[ $D{\'{e}}formation$ ]is one of the most important cultural factor which puts people at ease and gives a sense of security. This study, in the process, analyzes the works of Moschino. Moschino's designs are rated to have approached the sublime when it comes to transforming the psychological anxiety of everyday living into a laughter. After selecting one hundred-two of Moschino's designs from the Internet Web site(www.cft.or.kr, www.samsungdesign.net), this study examines and analyzes the characteristics and types of deformation found in them. The result as follows. The examination of deformation found in Moschino designs can be classified into a transformation, distortion, exaggeration, and illusion. Transformation, a conscious change of the existing form or function, was shown as the change of an existing position, form, function and designation of a new function. Distortion, an interpretation away from the reality or a "wrong interpretation," was shown by placing opposing factors in left-right position as an extreme asymmetry. Exaggeration, always beyond the realm of reality, was shown thorough an enlargement or a magnification of a specific part and a repetition of a detail factors. Illusion, through a distortion of reality results in something that looks new, was expressed through the effects of wearing a two-pieces, an expression of details, effects of wearing accessories, and an expression of a dynamism. Therefore, Moschino has reflected the desire of homo modern to transform the existing situation through many techniques of deformation.

PA(postero-anterior) and AP(antero-posterior) chest projections are the most sought-after types of all kinds of projections. But if a radiological technologist puts wrong information about the position in the computer, the orientation of left and right side of an image would be reversed. In order to solve this problem, we utilized CNN(convolutional neural network) which has recently utilized a lot for studies of medical imaging technology and rule-based system. 70% of 111,622 chest images were used for training, 20% of them were used for testing and 10% of them were used for validation set in the CNN experiment. The same amount of images which were used for testing in the CNN experiment were used in rule-based system. Python 3.7 version and Tensorflow r1.14 were utilized for data environment. As a result, rule-based system had 66% accuracy on evaluating whether the orientation reversal on chest x-ray image. But the CNN had 97.9% accuracy on that. Being overcome limitations by CNN which had been shown on rule-based system and shown the high accuracy can be considered as a meaningful result. If some problems which can occur for tasks of the radiological technologist can be separated by utilizing CNN, It can contribute a lot to optimize workflow.

The purpose of this paper is to justify the following four points. 1) Both communitarianism maintaining perfectionism and liberalism maintaining state neutralism are wrong. Communitarian liberalism is right. 2) If we accept a standpoint of communitarian liberalism, every state must make its own moral textbook for the achievement of common good. Of course, it dose not mean that a government must be an author of moral textbook. 3) The subjects of unification education and democratic citizenship education must be included in moral textbook. The crucial difference between moral education and civic education lies not in the educational subject but in the educational method. In order to internalize communal values and virtue, moral education prefer reflective internalization to indoctrination. But civic education prefer indoctrination to reflective internalization. 4) An desirable Korean who shares Korean values and virtue, provisional moral truth of Korea is a citizen of two isms, namely nationalism and cosmopolitanism.

What are the conditions make a being x a moral agent? Can an artifact be moral agent? A moral agent is considered to be a rational being capable of distinguishing between right and wrong. This study critically analyzed Davidson's position on the condition of the rational being and argued that the network of beliefs with propositional attitude and the beliefs as their background cannot be a requisite for the rational being. Later, it proves that the conditions proposed by $Proke{\check{s}}ov{\acute{a}}$ are merely paratactically listed superficial elements. The moral agent in this study includes the rational agent and it is proven that the strong first person viewpoint is the necessary and sufficient condition for rational agent and moral agent. In conclusion, it suggested a the sketch of moderate skepticism which sets the tentative limit on the agent potential in an artifact by suggesting conditions for moral agent instead of intense skepticism that strongly denies the potential as the moral agent.

With Seopa Ryu-Hee's Chunqiugwalyebulyu as the main research subject. this paper is to clarify characteristics in classification of the book's introductory remarks and its academic values. This book is a sort of synthetic collection of introductory remarks classification that defines standardized introductory remarks based on fundamental principles of Chunqiu introductory remarks. Seopa presented two fundamental principles for classifying Chunqiu introductory remarks. First, he clearly defined the nature and the system of the book Chunqiu, which was to present the background of classifying Chunqiu introductory remarks. Second, he declared that writing style and righteousness in Chunqiu serves as standard for classifying the introductory remarks. Seopa classified introductory remarks by type in accordance with these fundamental principles of introductory remarks in order to lay the groundwork for right interpretation of Chunqiu. Further, he was convinced that this classification of introductory remarks would block any chance of the book's wrong interpretation and at the same time, be able to remove the rationale behind distorted theories. This book can be appraised to have significant academic values in that it attempted standardization in classifying Chunqiu introductory remarks through systematic and synthetic analysis on various introductory remarks.

The present paper considers lice described in some premodern Korean proses, focused on the implications of lice and the literary strategies adopted by the writers in dealing with this unique subject matter. The works reviewed in this process are "A Story of the Louse and the Dog" by Lee Gyu-bo (Goryeo Dynasty), "The Old Man's Vindication of Lice" by Gwak Yeol (Early Joseon), "A Small Realization" by Yu Sin-hwan (Late Joseon) and "Miscellany" by Heo Jeon (Late Joseon). In these premodern essays, an allegory of lice was used to disclose various kinds of prejudices that people generally had: against things small (in "A Story of the Louse and the Dog"), against the old (in "The Old Man's Vindication of Lice"), against the dichotomous idea of right and wrong (in "A Small Realization") and against various aspects of life (in "Miscellany").

This study attempts to create an analytical framework of the transformation and transmission of knowledge by teachers to students. I focuses on the assertion that the cognitive thinking of a teacher is reflected in his use of mathematical language. Mathematical language is one of the critical elements of communicating mathematical knowledge to students. I examined the cognitive teaching style of different teachers as expressed in their use of mathematical language. An analytical framework of Mathematics Teaching styles was created integrating thinking factors of each visual and analytic style into 5 categories. After that, I regarding the teaching style of mathmatics teachers places its significance not on which teaching style is right or wrong but on identifying the strong and weak points of the teaching styles through actual analysis. With the help of this analytical framework, I conducted an analysis on the videotaped classes and found that the teachers were not biased to one side but in fact there were teachers who demonstrated visual, analytic or mixed teaching style. Therefore, I concludes that math teachers can analyze their teaching styles and improve them through the analytical framework provided in these findings.

Images of TV that crossed the reality & the virtual reality have been discussed for a long time, Then, With what feature can TV make messages of the reality & the virtual reality maintain to achieve such a target, and in which situation will the feature be exposed? One who answered first about these questions is a German critic, G$\ddot{u}$nter Anders. Anders called the reality confused with the reality and the confused world of the virtual reality Phantom, and thought human beings would live in the reproduced world created by media machine in the long run as a world that the Phantom created would be gloomy and confusing. The media, themselves, become images, and an image creates another image. Through this process, human beings became unaware of which image the reality was indeed. As TV often created these situations, we have been already seduced into the deep Phantom world before discussing right or wrong of the situation. Of course, the media reality & the reality can't be strictly distinguished. Because the means that help to form judgement of viewers is the media. The subject of practical judgement is the media reality not human beings.
