  • Sparse coding or independent component analysis (ICA) which is a holistic representation, was successfully applied to elucidate early auditor${\gamma}$ processing and to the task of sound classification. In contrast, parts-based representation is an alternative way o) understanding object recognition in brain. In this thesis we employ the non-negative matrix factorization (NMF) which learns parts-based representation in the task of sound classification. Methods of feature extraction from the spectro-temporal sounds using the NMF in the absence or presence of noise, are explained. Experimental results show that NMF-based features improve the performance of sound classification over ICA-based features.

  • A large body of previous studies investigated mathematical tasks by analyzing the design process prior to lessons or textbooks. While researchers have revealed the significant roles of mathematical tasks within written curricular, there has been a call for studies about how mathematical tasks are implemented or what is experienced and learned by students as enacted curriculum. This article proposes a mathematical task analytic framework based on a holistic definition of tasks encompassing both written tasks and the process of task enactment. We synthesized the features of the mathematical tasks and developed a task analytic framework with multiple dimensions: breadth, depth, bridging, openness, and interaction. We also applied the scoring rubric to analyze three multiplication tasks to illustrate the framework by its five dimensions. We illustrate how a series of tasks are analyzed through the framework when students are engaged in multiplicative thinking. The framework can provide important information about the qualities of planned tasks for mathematics instruction (proactive) and the qualities of implemented tasks during instruction (reactive). This framework will be beneficial for curriculum designers to design rich tasks with more careful consideration of how each feature of the tasks would be attained and for teachers to transform mathematical tasks with the provision of meaningful learning activities into implementation.

  • The purpose of this paper was to analyze a social discourse on the enactment of School Sport Promotion Law produced in the media. For this purpose, 73 articles related to the law collected from portal sites such as 'Daum', 'Naver' and 'Yahoo' as well as 'KINDS' were utilized for data analysis. Therefore, it was concluded that a social discourse's feature related to the enactment of the law is a social 'support' discourse calling for the enactment of the law, a 'denunciation' discourse after the rejection at the regular session of the National Assembly, a 'opposition' discourse concerned about the regression of elite sport and a 'wish' discourse expecting the leap and vitalization of school sport. From the holistic point of view, a dominant discourse is the appropriateness and necessity of the enactment of the law. However, smaller but stronger voices of dissent concerning about the decline in the development of elite sport (especially elite sporting success) were raised.

  • 'Transference phenomenon' is considered as a essential feature in psychotherapy as well as psychoanalysis. But there is much difference in conceptual and methodological issues for 'transference phenomenon' among various psychoanalytical schools. In general, the depth psychological studies for 'transference phenomenon' are mainly from the psychoanalytical view of point but relatively sparse from the analytical psychological view of point which has more holistic and deeper understanding for human psyche. So this article was intended for a comprehensive review of 'transference phenomenon' from the perspective of analytical psychology and tried to make an understanding for its meaning. To begin with, the concept of 'transference phenomenon' was investigated from the view before Jung and after Jung, with Jung's view in the center. Then it was made clear that 'transference phenomenon' from the perspective of analytical psychology could be understood by several characteristic aspects. It was suggested that a careful study on the symbolic meaning of the woodcuts' pictures in Rosarium Philosophorum including a proper interpretation of its posterior part to which Jung didn't refer in "The Psychology of The Transference" be devoted to the genuine understanding of 'transference phenomenon' from the perspective of analytical psychology afterwards.

Abstract Most existing digital libraries for document image retrieval provide a limited retrieval service due to their indexing from document titles and/or the content of document abstracts. This paper proposes a word spotting system for full English document image retrieval based on word image shape features. In order to improve not only the efficiency but also the precision of a retrieval system, we develop the system by 1) using a combination of the holistic features which have been used in the existing word spotting systems, 2) performing image matching by comparing the order of features in a word in addition to the number of features and their positions, and 3) adopting 2 stage retrieval strategies by obtaining retrieval results by image feature matching and applying OCR(Optical Charater Recognition) partly to the results for filtering purpose. The proposed system operates as follows: given a document image, its structure is analyzed and is segmented into a set of word regions. Then, word shape features are extracted and stored. Given a user's query with text, features are extracted after its corresponding word image is generated. This reference model is compared with the stored features to find out similar words. The proposed system is implemented with IBM-PC in a web environment and its experiments are performed with English document images. Experimental results show the effectiveness of the proposed methods.

  • Recently some people in learned circles of oriental medicine raised a Question about a terminological problem, i.e., 'oriental medical'. This question was thought as an attempt to find out the identity of oriental medicine which exists among the various current medical knowledge systems. In spite of same object, human body, there are diverse medical knowledge systems which has different concepts and theories. This come from the difference of a view of object which defines the experiences of that. The knowledge system of oriental medicine was established by the view of object in oriental medicine which depended on the way of thinking as Yin and Yang. The view of object in oriental medicine has come out in the special cultural soil, namely, the oriental world. Because of this the view of object in oriental medicine cannot be seperated from the oriental world view. What distintive feature does the oriental world view have? It can be summarized as the holistic, dynamical and organic ideas of the world. The term 'oriental medical' is being used to emphasize the characteristic and the peculiarity of the oriental medicine among the various medical knowledge systems. Can the current so called scientific method accept this peculiar and special method of oriental medicine? The efforts of philosophers who had been stimulated by the awful scientific achivements and had tried to find out the unified method penetrating through all the empirical science by mobilizing the logic and mathematics has became out of date for the raise of a question about the inductive method. On the contrary, the theses of theory-laden observation was accepted widely and the relativism was accepted as a new established theory. But the relativism has its own problem. The relativism was founded upon the concept, the incommensurability, which Khun and Feyerabend had proposed. This concept was criticized strongly by some of philosophers because of its own self-refuting. The view of object in oriental medicine has a relative characteristic in the aspect of its urge that in accordance with the perspective a different medical knowledge system can be possible. But our possible choice is the moderate conceptual relativism. Therefore if the view of object in oriental medicine includes the relative aspect, there is the 'conceptual relativity' between the knowledge system of oriental medicine and the western medicine. This preview an important aspect for the standardization and modernizing research of oriental medicine by lending the knowledge of the western medicine. And when we choose the moderate conceptual relativism, it means that we do not support the extreme relativism, that is, 'anything goes'. The concept of truth and rationality cannot be abandoned, and it plays the role of the norm on the knowledge system of oriental medicine and other knowledge systems of medicine in a limited meaning. And the view of object in oriental medicine has an organic view about the human body and the characteristic which wants to interpret the phenomena of human body by using the holistic method. But the availability of this method will be evaluated by the achievements of oriental medicine. Finally what relationship does the theory of oriental medicine have with the world the theory is applied to? It is recognized that the theory of oriental medicine has the instrumental characteristic. But it can be thought the instrumentalism is different from the oriental medical standpoint in the aspect that the instrumentalism seperates the theoretical existence from the observational existence sharply. Because in the oriental thinking way there is no seperation between the mind of observer and the object and no conflict between the idealism and the realism like the western world. For this problem there must be a further study.

  • Face Recognition has been an active research area because it is not difficult to acquire face image data and it is applicable in wide range area in real world. Due to the high dimensionality of a face image space, however, it is not easy to process the face images. In this paper, we propose a method to reduce the dimension of the facial data and extract the features from them. It will be solved using the method which extracts the features from holistic face images. The proposed algorithm consists of two parts. The first is the using of principal component analysis (PCA) to transform three dimensional color facial images to one dimensional gray facial images. The second is integrated linear discriminant analusis (PCA+LDA) to prevent the loss of informations in case of performing separated steps. Integrated LDA is integrated algorithm of PCA for reduction of dimension and LDA for discrimination of facial vectors. First, in case of transformation from color image to gray image, PCA(Principal Component Analysis) is performed to enhance the image contrast to raise the recognition rate. Second, integrated LDA(Linear Discriminant Analysis) combines the two steps, namely PCA for dimensionality reduction and LDA for discrimination. It makes possible to describe concise algorithm expression and to prevent the information loss in separate steps. To validate the proposed method, the algorithm is implemented and tested on well controlled face databases.

  • The purpose of the research is to understand the life of persons with disabilities caused by an accident by reconstructing their post-accident experiences. As a research tool, Fritz $Sch{\ddot{u}}tze's$ narrative interview was used, and three cases were analyzed in terms of a 'process structure of life'. After the researcher reconstructed each case, she sorted the cases comprehensively both according to the common features as well as to the differences among them. In doing so, the researcher came up with three characteristics of persons with disabilities caused by an accident. First, rather than identifying with their present life, the interviewees identified themselves with their life before the accident happened. Such identification problem is connected with their problem of accepting their handicap. And the interviewees identified themselves with disability groups. It showed that they feel more comfortable and secure among other people with disabilities than with families or friends. This makes them stay in the group of the disabled, in which they can understand and respect each other, rather than staying in a group in which people discriminate the disabled from able bodied and do not accept the disabled as equal members. Second, in their narration the interviewees told stories emphasizing their life after the accident happened. This feature can be compared with the experiences of those persons who underwent a trauma. Finally, it was found that our country's welfare policy for persons with disabilities caused by an accident is designed without differentiating people according to gender or educational background. Through these findings, the researcher intends to reflect on our country's current social welfare services and to look for new methods in order to implement proper social welfare practices.
