  • This paper focuses on the asymptotic stability of a class of neutral linear systems with mixed time-varying delay arguments. Using the Lyapunov method, a delay-dependent stability criterion to guarantee the asymptotic stability for the systems is derived in terms of linear matrix inequalities (LMIs). The LMIs can be easily solved by various convex optimization algorithms. Two numerical examples are given to illustrate the proposed methods.

  • This study analyses the difference of contents and tones of arguments among three Korean major newspapers, the Kyunghyang Shinmoon, the HanKyoreh, and the Dong-A Ilbo. It is commonly accepted that newspapers in Korea explicitly deliver their own tone of arguments when they talk about some sensitive issues and topics. It could be controversial if readers of newspapers read the news without being aware of the type of tones of arguments because the contents and the tones of arguments can affect readers easily. Thus it is very desirable to have a new tool that can inform the readers of what tone of argument a newspaper has. This study presents the results of clustering and classification techniques as part of text mining analysis. We focus on six main subjects such as Culture, Politics, International, Editorial-opinion, Eco-business and National issues in newspapers, and attempt to identify differences and similarities among the newspapers. The basic unit of text mining analysis is a paragraph of news articles. This study uses a keyword-network analysis tool and visualizes relationships among keywords to make it easier to see the differences. Newspaper articles were gathered from KINDS, the Korean integrated news database system. KINDS preserves news articles of the Kyunghyang Shinmun, the HanKyoreh and the Dong-A Ilbo and these are open to the public. This study used these three Korean major newspapers from KINDS. About 3,030 articles from 2008 to 2012 were used. International, national issues and politics sections were gathered with some specific issues. The International section was collected with the keyword of 'Nuclear weapon of North Korea.' The National issues section was collected with the keyword of '4-major-river.' The Politics section was collected with the keyword of 'Tonghap-Jinbo Dang.' All of the articles from April 2012 to May 2012 of Eco-business, Culture and Editorial-opinion sections were also collected. All of the collected data were handled and edited into paragraphs. We got rid of stop-words using the Lucene Korean Module. We calculated keyword co-occurrence counts from the paired co-occurrence list of keywords in a paragraph. We made a co-occurrence matrix from the list. Once the co-occurrence matrix was built, we used the Cosine coefficient matrix as input for PFNet(Pathfinder Network). In order to analyze these three newspapers and find out the significant keywords in each paper, we analyzed the list of 10 highest frequency keywords and keyword-networks of 20 highest ranking frequency keywords to closely examine the relationships and show the detailed network map among keywords. We used NodeXL software to visualize the PFNet. After drawing all the networks, we compared the results with the classification results. Classification was firstly handled to identify how the tone of argument of a newspaper is different from others. Then, to analyze tones of arguments, all the paragraphs were divided into two types of tones, Positive tone and Negative tone. To identify and classify all of the tones of paragraphs and articles we had collected, supervised learning technique was used. The Na$\ddot{i}$ve Bayesian classifier algorithm provided in the MALLET package was used to classify all the paragraphs in articles. After classification, Precision, Recall and F-value were used to evaluate the results of classification. Based on the results of this study, three subjects such as Culture, Eco-business and Politics showed some differences in contents and tones of arguments among these three newspapers. In addition, for the National issues, tones of arguments on 4-major-rivers project were different from each other. It seems three newspapers have their own specific tone of argument in those sections. And keyword-networks showed different shapes with each other in the same period in the same section. It means that frequently appeared keywords in articles are different and their contents are comprised with different keywords. And the Positive-Negative classification showed the possibility of classifying newspapers' tones of arguments compared to others. These results indicate that the approach in this study is promising to be extended as a new tool to identify the different tones of arguments of newspapers.

  • This paper is an attempt to find/make an entrance to John Hejduk's architecture. Based explicitly on both Karl Popper's model of knowledge production called 'conjecture and refutation' and Harold Bloom's theory of poetry called 'revisionism', this paper, in order to produce a new problem, mainly deals with an existing knowledge as an object to refute, that is, Michael Hays' interpretation of Wall House by Jacques Lacan's notion of the gaze, Hejduk's a pivotal architectural finding. The arguments underlying this paper are two: First, Hejduk, just like this paper, follows Popper's model and Bloom's theory in conducting his own architectural research. Secondly, he takes what might be called artist's attitude when absorbing previous knowledge and producing new one. These two arguments are made in the first part and then served as a basic propositions for further arguments. In the process of criticizing the way in which Hays explicates Hejduk's Wall House, this paper reaches two main arguments. First, Lacan's notion of the gaze is not proper specifically for the explication of it. However, it may be useful and even promising when dealing with other works such as Subject/Object and House of the Inhabitant Who Refused to Participate. Secondly, Freud's notion of 'uncanny', arguably Hejduk's strong architectural orientation, may serve much better as a main gate among possibly many ones in trying to open his architecture. It is considered that this might also serve as an important clue to solving mysticism remaining yet untouched in his architecture.

  • Purpose: The purpose of the study was to interpretate Caper's view of the aesthetical approach to nursing, to discover problems of her arguments, and to ultimately expand the horizon of the aesthetical thinking of nursing. Method: By means of the critical interpretation of Caper's paper, problems of her arguments were discovered. This then was suggested was the proper way of the aesthetical approach to nursing. Result: Caper's arguments of aesthetics were seen to be confused, regarding the pattern of the nursing art and the relationship between aesthetical knowing and practical art, and to have no the nursing's perspective as moral art. The proper paradigm for the distinct thinking of the nursing aesthetics could be offered here through applying some aesthetical theories as follows; a mode of aesthetical knowing could be characterized as emphatical awareness in relationship between nurse and client, and a practical art of nursing understood as moral art in sense of the expression of the human dignity. Conclusion: This study suggested fundamental theme for the proper aesthetical approach to nursing in view of the aesthetical knowing and the practical art. The horizon of the aesthetical thinking in nursing can be expended through the inquiry into aesthetical theories which offer theoretical the base for nursing as an art.

  • In this paper we have inferred the influence of Zeno on the construction of the potential infinite of Aristotle based on arguments of Zeno's paradoxes. When we examine the potential infinite of Aristotle as the basis of the ancient Greek mathematics, we can see that they did not permit the concept of the actual infinite necessary for calculus. The reason Why they recognized the potential infinite, denying the actual infinite as seen in Aristotle's physics could be found in their attempt to escape the illogicality shown in Zeno's arguments. Accordingly, this paper could provided one of reasons why the ancient Greeks had used uneasy exhaustion's method instead of developing the quadrature involving the limit concept.

  • The argument from ignorance that knowledge conclusion is derived from ignorance premises is claimed to be fallacious by many logicians such as I. Copi. According to them, some arguments from ignorance which seem to be acceptable are not really the arguments from ignorance. They say that such arguments have implicitly conditional knowledge premise. Against them, I argue that every argument from ignorance can be interpreted as having a hidden conditional premise, and that every argument from ignorance is not fallacious. I propose the criterion to judge which argument from ignorance is fallacious and which is persuasive. In particular, I argue that social contexts play a crucial role to judge whether a practical argument is fallacious or not.

  • This paper argues that the basic modes of spatial cognition can be best identified in terms of argument/participant location, and shows that natural language uses‘simple’types of semantic denotations to encode spatial cognition, and further notes that spatial expressions should be interpreted not as locating an event/state as a whole but as locating arguments/participants of the event. The ways of locating events/states are identified in terms of argument orientation(AO), Which indicates semantic patterns of linkiarticipant location. and shows that natural langrage uses ng locatives to specific arguments. Four patterns of argument orientation described here reveal substantial modes of spatial cognition. and the AO patterns are mostly determined by the semantic classes of English verbs combining with locative expressions, i.e., by the event type of the predicate. As for the denotational constraint of locatives, the paper concludes that semantic denotations of locative PPs are restricted to the intersecting functions mapping relations to relations.

  • This article reports some Korean EFL learners' cognitive tendencies drawn up from their responses to logical fallacies in the argument passages, and its pedagogical implications. The findings of experimental study show the meaningful disparities in three sets of judgment tests designed to identify and explicate faulty arguments: based on the three general types of fallacies using language, emotions, and distraction tactics, subjects on average gained the highest scores in the test questions with language-loaded fallacies and the lowest scores in those with emotion-based ones among the three different types; for this reason, the scores that subjects obtained in the test of distraction-loaded fallacious arguments fell in between the two poles. These discrepancies, mainly based on statistical inferences, support the possibility that the Korean EFL learners are most likely to be manipulated by emotions/distraction- loaded argument tactics than by language-based ones in the three types of fallacious arguments; and, they are least likely to be influenced by language-oriented trickeries. As a consequence, such variances in abilities to recognize the intrinsic elements of logical fallacies suggest some basic instructional approaches to critical reading of argumentative texts with due weights on the Korean EFL learners' culture-specific cognitive tendencies.
