In this paper, we introduce a newly developed photogrammetric software for automatic generation of high quality geo-products and its performance assessment carried out using various satellite images. Our newly developed software provides the latest techniques of an optimized sensor modelling, ortho-image generation and automated Digital Elevation Model (DEM) generation for diverse remote sensing images. In particular, images from dual- and multi-sensor images can be integrated for 3D mapping. This can be a novel innovation toward a wider applicability of remote sensing data, since 3D mapping has been limited within only single-sensor so far. We used Kompsat-2, Ikonos, QuickBird, Spot-5 high resolution satellite images to test an accuracy of 3D points and ortho-image generated by the software. Outputs were assessed by comparing reliable reference data. From various sensor combinations 3D mapping were implemented and their accuracy was evaluated using independent check points. Model accuracy of 1~2 pixels or better was achieved regardless of sensor combination type. The high resolution ortho-image results are consistent with the reference map on a scale of 1:5,000 after being rectified by the software and an accuracy of 1~2 pixels could be achieved through quantitative assessment. The developed software offers efficient critical geo-processing modules of various remote sensing images and it is expected that the software can be widely used to meet the demand on the high-quality geo products.

This study aimed to understand why small libraries, which have been continuously extended by the increase of social interest in them and the enactment of 「Promotion of Small Library Act」, an independent law about small libraries, are poorly activated. To this end, it examined the actual status of small library operation, related policies, support and legislations. By summarizing the results, it proposed a policy direction and tasks for activating small libraries. The policy tasks for activating them consist of three main tasks such as 'the improvement of laws and institutions for establishing the base of policies and securing practical momentum', 'the reestablishment of roles by policy units and the reinforcement of cooperation systems' and 'the construction of stable operation support system for small libraries', and their 14 sub-tasks, under the vision of 'the activation of small libraries support local residents' happy life' and the core value of 'a comprehensive policy ground, the innovation of policy systems and sustainable management support'.

The paper investigates the determinants of firm's standardization activity in the Korean service industry. Standardization variables as dependent ones are standardization management at the firm level, domestic standardization activity, and international standardization activity. The independent variables include innovative activities(R&D intensity and patent application), firm size, export ratio, network, and firm's organization characteristics. We estimated the logistic regression model, using the data from 102 Korean service firms. The empirical findings are as follows. First, R&D intensity has a positive effect on international standardization activity, but not on the standardization management at the firm level and domestic standardization activity. Second, patent application has a negative effect on the standardization management at the firm level. Third, firm size doesn't have any influence on firms' standardization activities in the service sector. Fourth, the level of chief executive officer's interest on standardization is a very important factor in determining firms' efforts to participate standardization process, regardless of types of standardization activity.

Consumption has generally become more fragmented, hedonic and individual specific, satisfying not only functional but also emotional needs. In parallel, customer satisfaction is now thought to be both a cognitive and affective response, and the closely related concept of job satisfaction is commonly seen as an emotional reaction. The reasoning within quality management does, however, still lean heavily toward cognitive judgements (i.e. performance ratings), the emotional component clearly being under explored. Further, performance variables have shown not to be significant in predicting satisfaction for certain 'experience products', the effect fully mediated by emotions. As a consequence a cognitive judgement based quality concept has lost its ability to predict satisfaction, which clearly contradicts with the modem quality definition, stressing quality as the ability to satisfy the customer. Emotions have however entered the quality discourse and it has been proposed that having customers that are merely feeling satisfied will not suffice. Instead, there has been a plethora of executive exhortations in the trade press calling on business to 'delight the customer'. Strategies for doing so have however usually been imprecise and unclear, and the different drivers of delight and satisfaction are not well explored. This paper aims to complement the previous cognitive dominance by exploring the multiple emotional responses involved in customer satisfaction. A conclusion being that we currently are measuring something, in terms of satisfied, that is more or less independent of what we aim for, in terms of delight. It is also most likely that - depending on the situation, product, and person - other positive and negative emotions are more important outcomes of purchase and usage than merely satisfaction. It is questioned whether a single, summary response such as satisfaction is feasible or even desirable.

Due to the change of future environment like high-rise building and the use of basement space etc, new types of disaster occur in recent years. The scale of disasters is changing to bigger than past and the environment of fire industry is varied with Korea-America FTA etc. As the reasons above expressed, the necessity of technical innovation of fire industry comes to the fore. Domestic fire products don't have competitive technique than one of developed countries and also don't have competitive price than one of Southeast Asia and China. It is very important that the independent fire industry must be established using R&D vitalization to overcome these problems. In this study, we have analysed the status of domestic R&D and the domestic fire industry R&D. And we suggested the problems of above analysis and improvement. Consequently, we want to suggest the development strategy through R&D vitalization.

The evolution of transaction-based business model is upon us. The business models of many e-Marketplace in their early stages have typically been based on transaction fees. Many e-Marketplaces have even called out transaction revenues as a core element of their business plans. The transaction business represents the most simple of business models, but it does not provide a long-term sustain able advantage. For buyer's convenience, wide selection and test price hold appeal. For suppliers, the extended global market reach and direct access to customers and consortiums of customers is powerful. To maxmize leverage of these new e-marketplace, you must from both a buyer perspective as well as a supplier perspective. Also required is a strategy that takes in account all of the various e-Marketplace transaction standards and one that allows the easy accomodation to new e-marketplace as the market change. These new e-marketplace will need to be factored into the sales channel strategies. To be successful, integration with these e-marketplaces should occur at a complete business process level. This study explored independent and industry-backed current and future business models that are emerging in the B2B electronic market industry, as well as value -added service models for the Net market maker industry. E-Marketplaces will evolve into digital work environments in which real industry collaboration can occur.

As a part of the KIAPS (Korea Institute of Atmospheric Prediction Systems) Package for Observation Processing (KPOP), we have developed the modules for Advanced Microwave Sounding Unit-A (AMSU-A) pre-processing and its bias correction. The KPOP system calculates the airmass bias correction coefficients via the method of multiple linear regression in which the scan-corrected innovation and the thicknesses of 850~300, 200~50, 50~5, and 10~1 hPa are respectively used for dependent and independent variables. Among the four airmass predictors, the multicollinearity has been shown by the Variance Inflation Factor (VIF) that quantifies the severity of multicollinearity in a least square regression. To resolve the multicollinearity, we adopted simple linear regression and Principal Component Regression (PCR) to calculate the airmass bias correction coefficients and compared the results with those from the multiple linear regression. The analysis shows that the order of performances is multiple linear, principal component, and simple linear regressions. For bias correction for the AMSU-A channel 4 which is the most sensitive to the lower troposphere, the multiple linear regression with all four airmass predictors is superior to the simple linear regression with one airmass predictor of 850~300 hPa. The results of PCR with 95% accumulated variances accounted for eigenvalues showed the similar results of the multiple linear regression.

As fashion has concentrated increasingly on inner values, it has become more directly connected with human life and society. This study analyzed anti-fashion, a movement that resists mainstream society and culture, which it views as causing inner conflicts such as competition, mammonism, consumerism, and egoism by fixating solely on the pursuit of growth and improvement. The study examined Kinfolk, an independent lifestyle magazine, to determine the essential values and principles that comprise this movement's refusal of mainstream modern society. The analysis of Kinfolk identified the following characteristics of, the Kinfolk lifestyle: essentialism, nature-friendliness, retro sensibilities, socio-ethical awareness, and diversity. Essentialism refers to the pursuit of essence, brevity, innovation based on tradition and slow life. Nature-friendliness involves communion with nature and humanity, animal-friendliness, de-industrialization, de-urbanization, and nomadic behavior. The components of the retro sensibility include nostalgia, and interests in vintage culture, and handcrafts. Diversity encompasses commonplaceness, various subcultures, agelessness, genderlessness, acceptance of other cultures, and new understanding. The analysis identified the tendencies of anti-fashion in Kinfolk magazine as simplicity, naturalism, resistance to novelty, ethics, and inclusiveness. Anti-fashion pursues the essential values of human life that have been lost or forgotten in modern society. It is important to pay constant attention to the values of minority, non-mainstream and indie cultures that represent anti-fashion. It exerts considerable influence and has great potential as an area for the development of various style-based paradigms rather than as a single fashion direction.

IT has been receiving increasing attention for cloud computing services. However, despite a lot of attention, there are limitations of existing research on cloud computing services. There are researches respectively about the benefits and costs that would occur if you choose a cloud computing services. However, in real life, consumers should be considered about the benefits and costs at the same time if they choose and use a cloud computing service. Therefore, this study examines the interaction effect of benefits and costs on cloud computing service. The findings demonstrate that three independent variables(usefulness, social influence, and innovativeness) positively(+) affect the perceived value. However, showed the benefits and costs of interaction effects analysis, usefulness and innovation on the cost influence the perceived value in statistics. The interaction of the usefulness & cost shows negative(-) effect and the interaction of the innovativeness & cost has positve(+) effect on the perceived value. In conclusion, this study provide that consumers need to consider costs with benefits when they use a cloud computing service.
