This paper aims to compare open source software (OSS) with proprietary software (PS), and to propose a new business model for OSS. Generally speaking, PS has made negative impact on software industry in various ways. In contrast, OSS may reduce negative aspects of lock-in effect and transaction cost the ways in which software distribution has been utilized. In this regard, OSS makes it possible to create a new business model, which is software customization. Software customization is not to sell software license directly to end-users, but to create values by means of developing and capitalizing software-related industries where value chain is linked. In other words, the new business model of OSS is focusing on software market where the value created by OSS can be enhanced.

This paper presents a new learning method for a noise tolerant Fuzzy ART. In the conventional Fuzzy ART, the top-down and bottom-up weight vectors have the same value. They are updated by a fuzzy AND operation between the input vector and the current value of the top-down or bottom- up weight vectors. However, it can not prevent the abrupt change of the weight vector and can not achieve good performance for a noisy input vector. To solve the problems, we updated using the weighted sum of the input vector and the current value of the top-down vector. To achieve stability, the bottom-up weight vector is updated using the fuzzy AND operation between the newly learned top-down vector and the current value of the bottom-up vector. Computer simulations show that the proposed method prominently resolves the category proliferation problem without increasing the training epoch for stabilization in noisy environments.

Digital image and video libraries require new algorithms for the automated extraction and indexing of salient image features. Eigen values of an image provide one important cue for the discrimination of image content. In this paper we propose a new approach for automated content extraction that allows efficient database searching using eigen values. The algorithm automatically extracts eigen values from the image matrix represented by the covariance matrix for the image. We demonstrate that the eigen values representing shape information and the skewness of its distribution representing complexity provide good performance in image query response time while providing effective discriminability. We present the eigen value extraction and indexing techniques. We test the proposed algorithm of searching by eigen value and its skewness on a database of 100 images.

The study, "a semiotic analysis on 1930′s costume", is based on semiotic theory which analyze the meaning of signs. In the novels, "흙" and "삼대", character′s costume were used as a visual language that implies massages of character′s status, class, and the view of value. Analyzing the meaning of clothing signs, clothing could deliver the people′s informations to others and could be first things when people accept new value. The object of the studies are the novels, Hulk(흙) and Samdae(삼대) which are written by lee, Kwang-Soo and Yeom, Sang-Seob. In the novels, the social structure is classed as modern and traditional after we accept the western cultures and institutions. The traditional clothing, Han Bok, were dressed by the conservative woman. However, we could find the modernized woman dress with the western dress and the modified traditional style. According to the result of the research, we could find that clothing could be a sign which indicates value and also clothing is one of the first thing to change when people acquired new value.

This study is the design case analysis of seamless knitwear in order to suggest a new direction of high value-added seamless knitwear and seek for its possibility. Seamless knitwear is the up-to-date knit product that is made by a knitting machine without sewing, and it maintains elasticity of a material itself and is the closest type to the essence of knitwear. The seamless knitwear can satisfy satisfaction of customers with more elegance and individuality and become a method to develop a high value-added design. This study suggests a new direction for the 21st century knitwear design through a practical approach of seamless knitwear designs, pursues a high value fashion, and contributes to improving national competitiveness of fashion industries in order to be a practical research data for seamless knitwear designs.

The aim of this paper is to provide a new model to evaluate the quantitative value of technology(nonfinancial benefits). This new model is based on the technology stock(technology level) ac-quired in R&D process. The model can explain the quantitative relation between the technology stock(level) and the market value of technology as considering the R&D expenditure to acquire technologies above a certain level(>70%) in comparison with the advanced country and the cost to prevent the technology obsolescence. The value of non-destructive testing technology which is one of the electric power technology is measured quantitatively as a case study.

In this paper, we propose a new paradigm of weighting methods for naive Bayesian learning. We propose more fine-grained weighting methods, called value weighting method, in the context of naive Bayesian learning. While the current weighting methods assign a weight to an attribute, we assign a weight to an attribute value. We develop new methods, using Kullback-Leibler function, for both value weighting and feature weighting in the context of naive Bayesian. The performance of the proposed methods has been compared with the attribute weighting method and general naive bayesian. The proposed method shows better performance in most of the cases.

Polyolefins show a very healthy growth rate among commodity polymer resins due to their low feedstock prices, recyclable and environmentally friendly characteristics and easily controllable performances. Capacity investment in polyolefin field is now moving from technology region to consumer region and feedstock region. Therefore, key success factors for polyolefin business in the other region such as Korea are cost reduction, development of highly value-added products and new applications and substitution of PVC, PS, PET and other EPs. To add additional value to commodity polyolefin products, high level of platform technology such as catalyst, process and structure-properties relationship is needed. Progress on polyolefin products has been very closely related to catalyst and process technology. According to this trend, SK Corporation has devoted a lot of research effort into development of new value-added polyolefin products based on the proprietary technology platform.

This paper proposes the new signal-to-noise ratio(SNR) that is different from the conventional signal-to-noise ratio (SNR) in direct-sequence code-division multiple-access communication system employing offset quadrature phase-shift keying(OQPSK) and using a chip waveform. The conventional SNR value is so different from a real SNR value. Therefore, we propose a new SNR equation approximated to real SNR. The multiple-access interference(MAI) in DS-CDMA communication system has an effect on SNR performance and MAI is concerned with the correlation functions of the chip waveform. For this reason, we considered all possible correlations of chip waveforms. In conclusion, the SNR value of proposed method is enclosed to the real SNR value.
