  • In this paper we discuss a deconvolution density estimator obtained using the support vector machines (SVM) and Tikhonov's regularization method solving ill-posed problems in reproducing kernel Hilbert space (RKHS). A remarkable property of SVM is that the SVM leads to sparse solutions, but the support vector deconvolution density estimator does not preserve sparsity as well as we expected. Thus, in section 3, we propose another support vector deconvolution estimator (method II) which leads to a very sparse solution. The performance of the deconvolution density estimators based on the support vector method is compared with the classical kernel deconvolution density estimator for important cases of Gaussian and Laplacian measurement error by means of a simulation study. In the case of Gaussian error, the proposed support vector deconvolution estimator shows the same performance as the classical kernel deconvolution density estimator.

  • This paper presents a flexural-torsional analysis of thin-walled open-section composite beams. A general geometrically nonlinear model for thin-walled composite beams and general laminate stacking sequences is given by using systematic variational formulation based on the classical lamination theory. The nonlinear algebraic equations of present theory are linearized and solved by means of an incremental Newton-Raphson method. Based on the analytical model, a displacement-based one-dimensional finite element model is developed to formulate the problem. Numerical results are obtained for thin-walled composite beams under general loadings, addressing the effects of fiber angle, laminate stacking sequence and loading parameters.

  • For bringing about a revolution in studying the classic literature the positivism must be overcome and the imaginative power about the history, literature and religion must be exercised. The theme of the monk-mask-play had been interpreted from the both viewpoint; the traditional mask play is the profane drama, but, on the other hand, it is the sacred drama. Judging from the social viewpoint, the sexual union of the old monk and the beauty symbolizes the reconciliation between the governing class and the production class. Judging from the viewpoint of the equalitarianism, that symbolizes the harmony of a masculinity and a femininity. Judging from the viewpoint of the education, that symbolizes the unification of reason and sensitivity. Judging from the viewpoint of the religion, that means the resurrection.

  • The purpose of this paper is the analysis of to point its structure and meaning deduced from the rite of passage. In the light of the rite of passage, could be retrieved its value as one of significant works among the works of Gangho-sijo. is composed of nineteen pieces of monotype sijo. The first piece is a kind of prologue. The other pieces are divided into three parts which correspond with the three stages of the rite of passage-separation, transition, incorporation. As a result of this analysis, we can find out the writer's cognitive change according to the schema of the rite of passage. It becomes clear that the space of Gangho means the sacred space for mental culture rather than a separate space for escape. And considering the withdrawal for Gangho as the transition process of the rite of passage, gives a description of the disentanglement of conflict and a incorporation into the superior position of spirit.

  • Today, in the case of literary works such as modern poetry, novels, 'literature production : literature acceptance' are relatively simple as 'writing : reading'. However, in classical literature, there are ways of 'singing, chanting, narrating, performing, public reading, writing : listening, reading.' Modern literary works such as poetry and novels are sole arts made up only of literature, but classical literature have many complex arts accompanied by music, theater, etc. In order to understand the way classical literature, it is necessary to consider music, theater, etc. also. There are a number of subjects to research today in relation to the accepting method of classical literature. There are such things at Hyang-ga (향가), Goryeo Sog-yo (고려속요), Sijo (시조) and Gasa (가사) in of classical poetry. There is a public reading in classical novels. There is securing video materialㄴ for narrators in oral literature. And there are Si-chang (시창. 詩唱) and aloud reading in chinese proses. 'Listening literature', such as the oral literature needs to have the A. Lord's 'formular theory' - 'formular' (general words), 'themes' (general subject), and 'improvisation.' It is the opposite of contemporary poetry and novels that value ' special words', 'special contents', and 'original text.' Classical literature with a great deal of 'listening literature' besides ' reading literature' needs to have this 'formular theory' too basically. In the case of 'excessive pornographic' oriented events in Goryeo Gayo (고려가요) and Pansori (판소리), a vision is required to set up a space for the realization of literature. The haman basic elements like a man and woman's body subject can be evoked as a literature means at open place for anonymous people. Unlike modern poetry and novels, which are 'reading literature', and contain only literature, classical literature have 'listening literature' besides 'reading literature', and have complex arts - classical poetry (literature and music), and oral literature (literature, music, theater etc.) These aspects are available to research modern mass media literature, which are all 'listening literature,' and all complex arts - pop songs (literature and music), movies (literature, drama, image, music etc.) and TV dramas (literature, drama, image, music etc.). Thus, a proper understanding and consideration of the accepting method is very important in understanding, researching and educating classical literature.

  • RHadoop is a collection of R packages that allow users to manage and analyze data with Hadoop. In this paper, we implement K-Means algorithm based on MapReduce framework with RHadoop to make the clustering method applicable to large scale data. The main idea introduces a combiner as a function of our map output to decrease the amount of data needed to be processed by reducers. We showed that our K-Means algorithm using RHadoop with combiner was faster than regular algorithm without combiner as the size of data set increases. We also implemented Elbow method with MapReduce for finding the optimum number of clusters for K-Means clustering on large dataset. Comparison with our MapReduce implementation of Elbow method and classical kmeans() in R with small data showed similar results.

  • Classicism pursued beauty comprised of a perfect form, and beauty was perceived as a state of sufficiency. Accordingly, a completed and permanent beauty was sought after; as a result, a perfect and flawless form became the mainstream, and there was an effort to visualize the eternal proportional perfection. In classicism, forms were perfectly embodied with systematic inevitability and absolute inflexibility, by which an extremely clear aspect appeared. This study analyzes a classical construction paradigm in modern fashion according to the five categories: 'Harmony and order by numerical proportion', 'Clear form', 'Simplification of form and two-dimensional Seh-form', 'Completed contracture structure', and 'Pluralistic unification', and the respective formative characteristics are as follows. First, in terms of the formative aspect of modern fashion,'Harmony and order by numerical proportion' results from thorough observance of extreme and golden section (proportion of 5 :8) which was an aesthetic standard of beautiful body in classicism. Second, 'Clear form' appears in clothes as individual clearness of structural elements expressing each part of body, and shows a well-established form possible to be grasped with equal and clear contour line. Third,'Simplification of form and two-dimensional Seh-form' comes out as form composition, single line, single layer structure, two-dimensional form and arrangement of elements of clothes through the front viewpoint caused by 2D diagramming work while fashion-designing and producing. Also, it is seen that two-dimensional proportion which is composed of sections through various harmonious lines and sides according to the simple two-dimensional compatibility principle is accomplished. Fourth, 'Completed contracture structure' emerges as an expression of stationariness, in other words, fixation of an overall impression. This is a tendency that the overall form is grasped as a fixedly intact shape without a big change of the silhouette of clothes. Fifth, 'Pluralistic unification' means that it respectively emphasizes all the parts composing clothes by making them individually independent at the same time as each element is inclusively shown with the harmony of the overall silhouette of clothes and many other details. This study examined classical formative characteristics through a theoretical research on a formative paradigm revealing the classical style. Also, the significance of classical or rational value of art was illuminated by observing what characteristics a classical formation paradigm shows in modern fashion. As a result, classical characteristics in modern fashion prove that classicism is not a merely past construction style separated from the present but a construction paradigm deeply involved in our reason system.

  • In this thesis, we investigate the animation (2001) based on the three phases of the lyrical expression derived from Ye Weiqu's Mono no aware Aesthetic-a Japanese classical aesthetics' perspective, on the aspects of the perceptions of human, world, and nature. By analyzing each component of three phases of Mono no aware Aesthetic, the thesis illustrated that how (2001) utilized and expressed Japanese classical aesthetic and how Japanese classical aesthetics were widely utilized into modern Japanese animations. Moreover, the thesis also stated that Mono no aware Aesthetic has become a creative element in order to answer a development direction with future Japanese animations. Through integrating Japanese unique classical aesthetics into the animation elements, Satoshi Kon, the director of the animation, well carried and expressed the cultural content of Japanese nation, thus promoting a deep understanding of characteristics for Japanese animation which have a wide appeal. In his masterpiece -, the characters building, plot describing, theme expressing, cultural meaning could be analyzed respectively by means of Ye Weiqu's 3 phases of Mono no aware aesthetic, reflecting how inherited the legacy of Japanese classical aesthetics. Furthermore, based on the analysis method, the animation contributed tremendously to Japanese classical aesthetics and Mono no aware aesthetics. Tradition for classical aesthetics could play a role as a creative tool for contemporary and future animation.

  • In this paper a support vector method is proposed for use when the sample observations are contaminated by a normally distributed measurement error. The performance of deconvolution density estimators based on the support vector method is explored and compared with kernel density estimators by means of a simulation study. An interesting result was that for the estimation of kurtotic density, the support vector deconvolution estimator with a Gaussian kernel showed a better performance than the classical deconvolution kernel estimator.

  • We propose the Bayesian testing for the equality of K-exponential populations means with Type-II censored data. Specially we use the fractional Bayesian factors suggested by O'Hagan (1995) based on the noninformative priors for the parameters. And, we investigate the usefulness of the proposed Bayesian testing procedures via both real data analysis and simulations and compare the classical likelihood ratio(LR) test with the proposed Bayesian test.
