Recently, various methods of text embedding using deep learning algorithms have been proposed. Especially, the way of using pre-trained language model which uses tremendous amount of text data in training is mainly applied for embedding new text data. However, traditional pre-trained language model has some limitations that it is hard to understand unique context of new text data when the text has too many tokens. In this paper, we propose self-supervised learning-based fine tuning method for pre-trained language model to infer vectors of long-text. Also, we applied our method to news articles and classified them into categories and compared classification accuracy with traditional models. As a result, it was confirmed that the vector generated by the proposed model more accurately expresses the inherent characteristics of the document than the vectors generated by the traditional models.

Computational models up to now for Korean morphology have been linear in that it deal with only segmentation of morphemes rather than formation of the internal structure of a word. When integrating a linear computational model with syntax analysis, it requires an additional interface component between this model and the syntax to bind morphemes into sentence constituents. Furthermore the linear model is not semantically intuitive. In this paper, based on word-syntactical viewpoint, we propose an integrated computational model that deals with morpheme segmentation, formation of syntactic element (sentence constituent), and even internal structure of word. Formalism of two-level morphology is employed to cope with morpheme segmentation and alternation problems, and functional diacritics are proposed to incorporate categorial context into the two-level formalism. A modified GLR-based algorithm is also proposed to check syntactical constraint of morphemes.

Feminist critics have criticized Aristotle as a sexist, misogynist, male chauvinist or masculinist, or, at least, their chief spokesman. Indeed, he says in the Politics that the male is by nature superior to the female and, also, that women possess the same deliberative part of the soul as men, but without authority, etc. In the Generation of Animals, he claims that the male supplies the form and the efficient cause, whereas the female supplies the material cause only in reproduction and describes the female as a mutilated being. When these remarks of Aristotle are read without considering their overall context, it hardly seems possible for him to escape from such severe criticism and condemnation. On the contrary, in what follows, I shall claim that the criticism and condemnation that has been ascribed to him is unfair. Although it is undeniable that Aristotle has made such remarks, it does not immediately follow that he was a sexist. In particular, I shall show his view on the status of men and women by analysing the value of matter and form ascribed in two of his main philosophical theories, the theories of hylomorphism and four causes. In consequence, we shall arrive at the conclusion that, since the theories do not imply the significance or necessity of either form or matter alone, but of both, there is no sign of sexism or misogyny or male chauvinism in Aristotle.

In this thesis, the author will examine how modern philosophical expression manifests in the field of ethics based on Kant's Ethics. The author will critically assess whether Kant's Ethics is an appropriate rational theoretical alternative to overcome today's ecological crisis. In the first section, the author lists the characteristics of modernity. The purpose of this section is to show why Kant's Ethics must be understood in the context of modern age and how his ethics expresses the ideology of the modernity(I). In the second section, the author will analyze the challenge Kant's Ethics face in relation to ecological crisis from the context of dualism between person and thing(II). In the last section, the author will inspect the flaw of Kant's Ethics based on his positive position regarding vicarious duties toward animals, and pose the basic direction of the theory of ecological publicness that can overcome the limits of Kant's Ethics in the context of a critical reconstruction of neo-confucian tradition(III).

A hierarchical classification scheme, which can reduce the spectral ambiguity and also reflect crop cultivation patterns from past land-cover maps, is presented for the purpose of the early production of crop classification maps in large-scale crop areas. Specifically, the effects of mixed pixels are minimized not only by applying a hierarchical classification approach based on different spectral characteristics from crop growth cycles, but also by considering temporal contextual information derived from past crop cultivation patterns. The applicability of the presented classification scheme was evaluated by a case study of Iowa State in USA with time-series MODIS 250 m Normalized Difference Vegetation Index(NDVI) data sets and past Cropland Data Layers(CDLs). Corn and soybean, which are major crop types in the study area and also display spectral similarity, could be properly classified by applying different classification stages and accounting for past crop cultivation patterns. The classification result by the presented scheme showed increases of minimum 7.68%p and maximum 20.96%p in overall accuracy, compared with one based on purely spectral information. In addition, the combination of temporal contextual information during classification was less affected by the number of NDVI data sets and the best overall accuracy of 86.63% was achieved. Thus, it is expected that this classification scheme can be effectively used for the early production of large-area crop classification maps in major feed-grain importing countries.

Background : Arterial hypoxemia has been noted in patients with liver cirrhosis because of bronchial vessel dilatation. Cabenes et al. reported that bronchial hyperresponsiveness to the metacholine inhalation was observed in patients of left side heart failure, he suggested that one of the mechanism was bronchial vessel dilatation. We hypothesized that patients of liver cirrhosis might have bronchial hyperresponsiveness to metacholine inhalation due to portal hypertension. We evaluate the relationship between bronchial responsiveness and severity of liver cirrhosis, severity of portal hypertension. Methods : In the 22 patients of the liver cirrhosis with clinical portal hypertension, metacholine provocation test was done and determined $PC_{20}FEV1$. We classified liver cirrhosis according to Pugh-Child classification. Esophagogastroscopies were performed for the evaluation of the relationship between bronchial hyperresponsiveness and severity of esophageal varix. Results : In the 22 cases of the liver cirrhosis with clinical portal hypertension. The causes of liver cirrhosis, alcoholic hepatitis was 9 cases, hepatitis B virus was 12 cases, hepatitis C virus was 1 case, and 151 cases (68.18%) of total 22 cases were positive in metacholine provocation test. In positive cases. There was no significant relationship between $PC_{20}FEV1$ and severity of liver cirrhosis which were classified by Pugh-Child classification or severity of esophageal varix(p<0.05). Conclusion : we observed that bronchial responsiveness to metacholine increased in the patients of liver cirrhosis and there was no significant relationship between the severity of liver cirrhosis and the severity of esophageal varix.

This study is a link in a chain which grope for the description of puppet performance history. This study imply my intention which is not a description of puppet performance 'history' but a description of 'puppet performance' history. Object materials of this study is materials connected with puppet performance from ancient times to Chosun dynasty. Object materials of this study include not only records but also remains and pictures. Discussion start with regulation of puppet performance materials and establishment of a classification criterion. As a result of that discussion, the age of puppet performance is as follows: 'the age of diverse use of puppet', 'the age of ritual puppet performance of worship', 'the age of play puppet performance of handling', 'the age of ritual puppet performance of display', 'the age of ritual puppet performance of expulsion', 'the age of ritual puppet performance of handling', 'the age of play puppet performance of display', 'the age of play puppet performance of handling and voice-acting'. According to the internal division of age, the description of puppet performance history which is spread chronologically is attempted. As a result of the description, I confirm that puppet performance reveal a one's unfolding process. And a distinct aspect from the general cultu! re history is found. The development process which is a changeover that is 'from ritual puppet performance to play puppet performance' is amended by a circulation of ritual puppet performance and play puppet performance'. And the development process which is a changeover 'from static puppet to dynamic puppet' is amended by a circulation of static puppet and dynamic puppet'. Like this the thing which is laid in the inside which is not a one sided changeover but is a circulation is said that from one age of puppet performance to other age of puppet performance is not a close of former puppet performance tradition. Unfolding from one age to other age, on the other hand former puppet performance reveal aspect which is a continuance and change with a one's vitality. And a relation of mutual influence is exist between the ritual puppet performance and the play puppet performance on a large scale, among the puppet performance types on a small scale. this also don't overlook in cas! e of a groping of puppet performance history.

Students are exposed to a concept of tangent from a specific context of the relation between a circle and straight lines at the 7th grade. This initial experience might cause epistemological obstacles regarding learning concepts of tangent to additional curves. The paper provides a method of how to introduce a series of concepts of tangent in order to lead students to revise and improve the concept of tangent which they have. As students have chance to reflect and revise a series of concepts of tangent step by step, they realize the facts that the properties such as 'meeting the curve at one point' and 'touching but not cutting the curve' may be regarded as the proper definition of tangent in some limited contexts but are not essential in more general contexts. And finally students can grasp and appreciate that concept of tangent as the limit of secants and the relation between tangent and derivative.

In this paper, we attempted to extract binary relations between terminologies using composite kernels consisting of convolution parse tree kernels and WordNet verb synset vector kernels which explain the semantic relationships between two entities in a sentence. In order to evaluate the performance of our system, we used three domain specific test collections. The experimental results demonstrate the superiority of our system in all the targeted collection. Especially, the increase in the effectiveness on KREC 2008, 8% in F1, shows that the core contexts around the entities play an important role in boosting the entire performance of relation extraction.
