  • We propose a method to construct composite feature vector based on discriminant analysis for face recognition. For this, we first extract the holistic- and local-features from whole face images and local images, which consist of the discriminant pixels, by using a discriminant feature extraction method. In order to utilize both advantages of holistic- and local-features, we evaluate the amount of the discriminative information in each feature and then construct a composite feature vector with only the features that contain a large amount of discriminative information. The experimental results for the FERET, CMU-PIE and Yale B databases show that the proposed composite feature vector has improvement of face recognition performance.

  • A holistic representation, such as sparse ceding or independent component analysis (ICA), was successfully applied to explain early auditory processing and sound classification. In contrast, Part-based representation is an alternative way of understanding object recognition in brain. In this paper. we employ the non-negative matrix factorization (NMF)[1]which learns parts-based representation for sound classification. Feature extraction methods from spectrogram using NMF are explained. Experimental results show that NMF-based features improve the performance of sound classification over ICA-based features.

  • In this paper, we present a novel method to extract face representation based on multi-resolution spatial pyramid. In our method, a face is subdivided into increasingly finer sub-regions (local regions) and represented at multiple levels of histogram representations. To cope with misaligned problem, patch-based local descriptor extraction has been also developed in a novel way. To preserve multiple levels of detail in local characteristics and also encode holistic spatial configuration, histograms from all levels of spatial pyramid are integrated by using dimensionality reduction and feature combination, leading to our spatial-pyramid face feature representation. We incorporate our proposed face features into general face recognition pipeline and achieve state-of-the-art results on challenging face recognition problems.

  • The aim of this study is to identify the formative feature of the Chippendale style of the 18th century and to understand the aesthetic feature of the Chippendale style applied in the modern fashion. This is significant in that new possibilities are proposed in fashion design in more holistic and multifaceted views by comparing and delving into the fashion vis-a-vis other fields in a bigger scope of the formative art. The Chippendale style furniture is a combination of various styles of different eras and regions such as Gothic and Chinese style based on the Rococo style. Today, It is regarded in fashion as a composite design of heterogeneous elements or very curvy decorative design. The Chippendale style of this kind is classified into the Rococo style, Gothic style and Chinese style. Depending on each classification, formative features including curves, asymmetry, decorativeness, geometrical feature, exoticism, compositeness and graceness were derived. In comparative studies, fashion and furniture of the Chippendale style have the similarity in formative features but there were some differences in the expressive method. This study analyzed the formative features of the Chippendale style represented in furniture and the modern fashion based on the Rococo-revival design in the modern fashion starting from 2000.

  • The purpose of this article is to analyse the expenditure structure of the welfare mix; in order to grasp the holistic feature of the Korean social welfare. Most of all, the article attempts to elaborate the estimation methods of social welfare expenditure by including the components from which has been excluded so far - indirect tax expenditure of the government, nursery payments of households, life insurance pay-outs for survivors, inter-household private income transfers and the value of caring work of the family. In so doing, the article estimates that the total social welfare expenditure including state, enterprise, market, NPOs and family reached at 24.7% of GDP in 2000, which is approximately 2.5 times more than public social welfare expenditure. It implies that non-state, private sectors dominates the structure of social welfare provisions in Korea. In addition, based on the analyses of the expenditure structure, the article defines the main feature of Korea's welfare mix as the 'mixed structure of the welfare mix dominated by the protective family', or 'expanded public sector, relatively limited market, and protective family'. Such a family-dominated welfare mix structure in Korea indicates that the fundamental source of solidarity of the Korean social welfare system is family and, therefore, the welfare regime of Korea can be classified as 'Conservative'.

  • The opinion of user on a certain product is expressed in positive/negative sentiments for specific features of it. In some cases, they are expressed for a holistic part of homogeneous specific features, or expressed for product itself. Therefore, in the area of opinion mining, name of opinion features to be extracted are specific feature names, holonyms for theses specific features, and product names. However, when the opinion target is described with product name or holonym, sometimes it may not match feature name of opinion sentence to true opinion target intended by the reviewer. In this paper, we present a method to extract opinion targets from opinion sentences. Most importantly, we propose a method to extract true target from the feature names mismatched to a intended target. First, we extract candidate opinion pairs using dependency relation between words, and then select feature names frequently mismatched to opinion target. Each selected opinion feature name is replaced to a specific feature intended by the reviewer. Finally, in order to extract relevant opinion features from the whole candidate opinion pairs including modified opinion feature names, candidate opinion pairs are rearranged by the order of user's interest.

  • This study analysed theory and application of holistic innovation policy in the 3rd generation innovation policy with cases of Finland and Korea. Innovation policy areas of both countries are expanding from simple goal of economic development to extensive goals such as sustainable development, quality of life, balanced growth etc. Also administrative system changed in order to let technical innovation on the center of national operation and reorganized relation and structure of relative policies like manpower, education, region policy. Particularly, Korea is in embryo standing for S&T driven society since Noh's government. But, there are differences in embodiment degree and feature between both countries. Finland reinvigorate field of public opinion due to corporatism tradition as a Scandinavian institution. Government support system developed co-program and co-policy beyond territory of individual ministry to raise policy effectiveness. However, concept of the Korean innovation policy is ahead of the times but maintained framework of developing country. And there is no active participation of private sector and civil society because transition process accomplished on the top-down method, It could hardly progress toward transition in spite of various efforts to carry out a reform.

  • This study mathematically and scientifically investigated the aesthetic consciousness of women inherent in the costume craftworks craftworks of the Chosun Dynasty through a systematical analysis of their textile pattern composition using visual language theory. The tangent value from the horizontal and vertical ratio of the costume craftworks craftworks indicated that they had an indigenous proportion system with a relatively regular form and pattern but without an exaggerated type. There was a module based on structures in the textile patterns of the costume craftworks craftworks and the patterns were constructed by the module with the syntagms of the ratio structure. Moreover, the analysis of the pattern designs indicated that the whole form of the costume craftworks craftworks was built through a repetitive structure of feature and one of pattern units; in addition, the craftworks had the extended composition and blank space of daring patterns, an important factor to make a whole design. Therefore, our study suggested that the costume craftworks craftworks of the Chosun Dynasty was characterized by the presentation of the aesthetic style with a Geumgang ratio (an indigenous proportion system used in Korea) and could be interpreted as an art style based on the beauty of space. Moreover, it is suggested that the spirit inherent in the costume craftworks of the Chosun Dynasty (which tried to understand the whole as one and equate the whole and parts) might agree with a holistic tendency as the foundation of Korea art.

  • This paper presents a new holistic development approach for the carbon continuous-fiber composite frame of an automotive sunroof assembly. The original steel frame has been designed to get higher bending stiffness with its corrugated cross-sectional shape. The new approach uses the prepregs of a fast cure epoxy and PCM manufacturing processing. For higher productivity, the new frames feature a very simple plat cross sectional shape but achieve high bending stiffness through the laminate design. The sandwich structure with a PET foam core was presented. The frames were made of carbon UD laminae covered single carbon fabric on the outer surfaces. The fabrics provide torsional stiffness and also hold the carbon UD fibers floating in the low viscous epoxy resin of prepregs at the curing temperature during processing. The final product yields approximately 18 % savings in weight compared with the original.

  • Recent advances in systems biology are shedding a new light on the traditional medicine research. The systems biology highlights the way each component interacts with each other within a system, and the network behavior that emerges from such interactions. This feature of systems biology can accent the systemic aspects of Korean medicine such as the mechanism of action of herbal formulae, pattern differentiation, and the meridian systems, as both the Korean medicine and the systems biology theorize the human physiological functions and phenomena from a holistic point of view. This paper outlines the meaning of the recent Korean medicine research using the systems biology methodology. We discuss the methodologies of the two fields in a comparative manner, and overview the advantages and limitations of the integrated approaches. Finally, we suggest the future prospects for the systems biology inspired approaches to the Korean medicine research. The systems biology may provide a new modernized research methodology for the Korean medicine that can highlight its unique features.
