  • A Bayesian model-based clustering method is proposed for clustering objects on the basis of dissimilarites. This combines two basic ideas. The first is that tile objects have latent positions in a Euclidean space, and that the observed dissimilarities are measurements of the Euclidean distances with error. The second idea is that the latent positions are generated from a mixture of multivariate normal distributions, each one corresponding to a cluster. We estimate the resulting model in a Bayesian way using Markov chain Monte Carlo. The method carries out multidimensional scaling and model-based clustering simultaneously, and yields good object configurations and good clustering results with reasonable measures of clustering uncertainties. In the examples we studied, the clustering results based on low-dimensional configurations were almost as good as those based on high-dimensional ones. Thus tile method can be used as a tool for dimension reduction when clustering high-dimensional objects, which may be useful especially for visual inspection of clusters. We also propose a Bayesian criterion for choosing the dimension of the object configuration and the number of clusters simultaneously. This is easy to compute and works reasonably well in simulations and real examples.

  • Semi-supervised learning has gained significant attention in recent applications. In this article, we provide a selective overview of popular semi-supervised methods and then propose a simple but effective algorithm for semi-supervised classification using support vector machines (SVM), one of the most popular binary classifiers in a machine learning community. The idea is simple as follows. First, we apply the dimension reduction to the unlabeled observations and cluster them to assign labels on the reduced space. SVM is then employed to the combined set of labeled and unlabeled observations to construct a classification rule. The use of SVM enables us to extend it to the nonlinear counterpart via kernel trick. Our numerical experiments under various scenarios demonstrate that the proposed method is promising in semi-supervised classification.

  • Religion affects all the dimension of human beings, and at the same time it forms one dimension of human beings. Costume Is considered as a result that reflects the phases of the time and the characteristics of a wearer. Costume, also, has been influenced by religion that has led one's belief, social spirit and culture for a long period of time. The Eastern aesthetics has expanded the area of thoughts with the concepts that originated from Buddhism, Taoism, and Confucianism. Among the concepts, Non-Dualistic Theory is the core idea of Buddhism.'rho theory contains the moaning that one should not lean to one side between existence and nonexistence and should not be obsessed with the center. It was the most powerful Buddhistic idea that had an influence on Asian aesthetics. Korean traditional costume is not an exception. This study has a significance that it was conducted to understand the relation between religious principle and traditional custom through mainly using documentary records. The formative characteristics of Korean traditional costume influenced by Non-Dualistic Theory ran be summarized as non-structure like, indeterminate forms, amorphousness and anti-decoration such as plainness, temperance and achromatic color. Aesthetic value was expressed through 'the aesthetic of emptiness', 'the aesthetic of hiding', and 'the aesthetic of nature'. Although the appearance of a religious symbol can change, an essential element in religion lasts as human society remains. Although our clothing culture has converted to western style, Korean traditional aesthetics is placed deep inside of 'the Koreans' spirit and has a consistent effect on our overall culture of clothing.

  • This paper examines the aspects of the inferences between the dimensional terms in Korean, and attempts to give an account of the inference patterns based on the interaction of gestalt and position properties of spatial objects. Following Lang (1987) and Lang, Carstensen & Simmons (1991), we advance the idea that the inferences are possible for the same axis of a spatial object, if some contextually induced positional specifications are reversed to the inherent proportion schema. Two simple inference rules are proposed and justified. They are applied under the assumption that the inferences of the dimensional terms are drawn in a unidirectional way, i.e, from the Primary Perceptional Space to the Inherent Proportional Schema.

  • At the beginning of 21st Century, human desire of communication is forwarding to the Cosmos The way of Communication is going to be not by simple methodology but by the complicated methodology with high technology. It will not be monologue communication but be interactive communication, that will make intelligence Infra, which could be able to communicate from the location of information is present to which is not present; and the multi-media which will be able to solve the technical problems of these communication; will be developed continually. In the genre of plastic art, there are no exception in these changedness. More developed and proceed to develope intermedia could be able of intercommunication. The more development of technology could be able to the more development of new plastic art. Furthermore the development of science make the genre of art to be changed. There are no exception of this changedness in any part of society, The art always has been guided by the person who has proceeding idea for new value. The 21st century plastic art will be in the procedure of the intercommunication. Human-being's concern is to communicate with Universe, and that will be multi-dimension$(4{\cdot}5{\cdot}6{\cdot}7{\cdots}dimension)$ communication beyond our usual recognition. To conjoin this, the possibility of cyber space expressing is going to be considered, and the way is being done by the development of the Media Art, which is able to go and back to the cyber-space. And the message will be so complicate beyond our recognition. Because we will need to communicate with various newly-built vocabulary, so we need to magnify the repertories of new vocabulary.

  • The first attempt in architectural design theory to consider the perceptual and metaphysical dimension separately with a fully modern scientific manner, which exist in contrast to the Renaissance idea, was Claude Perrault, who emphasized the cognitive factors as an important scientific human issue in building design in 1683 in his book "Ordonnance". Even today many elaborated works to reveal the mysterious design processes based on a set of rational approaches have been introduced since the Design Method movement in 1960's. Their pioneering and challenging efforts to rationalize design process have been mostly rely on the cultural issues whether it takes a qualitative or quantitative stance. On the other hand, however, today's computer generated free form architecture seems not to be aware of those lessons learned from the past and, therefore, this study conducted an extensive research through exploring on morphological building forms with cultural issues to fill up the missing and/or lacking characteristics of today trend in building design.
