The main purpose of this study is to analyse the digital divide and th determinants of ICT diffusion rate in Korean industries. We estimate the ICT diffusion function using the pooling data for this analysis. The results are as follows. First, the ICT capital accumulated in machinery & equipment, electrical machinery and construction industry is estimated to be 83% of total In capital stock in the 90s. Second, using the panel analysis, we find positive correlation among ICT diffusion, network effect and accumulation of human capital, which is more prominent in the service sector. Third, the estimation results show that the additional 1% increase of human capital accumulation will allow to increase the 0.69% of ICT capital intensity in Korean industries.

The purpose of this paper is to analyze economic adequacy by estimating the benefit-cost for bird eco-park, eco-center, eco-river, and eco-waterway, which will be built in the new town of Kimpoo, Yangchon. This paper attempts an economic analysis for the development of an eco-friendly new town. The rates of B/C (benefit-cost) in all scenarios are over one. Especially, the B/C rate of the eco-center is the most efficient of the four eco-facilities by 5.02 - 3.75. In addition, the construction costs of the five eco-facilities are assumed to be 50 percent higher, though their economic soundness is maintained. This paper implies that providing ecological variety is one of the core components in constructing housing complexes and suggests that the construction of housing be harmonized with zero-carbon and energy efficient methods.

Recently, LVDC(Low Voltage Direct Current) has been came into the newly spotlight with HVDC(High Voltage Direct Current) and as increasing digital load, DC power supply and high quality of demand is also getting extended. In accordance with the report of EPRI(Electric Power Research Institute), they expect digital load will grow to 50% of whole load in 2020. Subsequently, the use of DC equipment will grow dramatically. Therefore, the careful adoption of LVDC standardization policy is urgently required for the safety of people, prevention of confusion and occupancy of the market.

Many studies make us difficult for understanding the specific concept of NOW avant garde by misusing avant garde or by using the over wide-ranging concept. The purpose of this study is to define the concept of NOW avant garde fashion by analyzing its fashion and its paradigm characteristics, after considering modern avant garde fashion history. This study was used with bibliographic research as well as internet search of qualitative method for analyzing fashion show clothes since 2005 women's wear. The characteristics of NOW avant garde fashion are classified into plural deconstructivism, econonism that integrates the last avant garde factors with logical economics, and the aesthetic of Tech-Human. To conclude, the concept of NOW avant garde fashion is defined as the fashion expressing either the digital-hybrid images or the deconstructive images meaning elimination, unification or confinement, being pilled up one on another, bizarre connection, transposition, and distortion.

Chaos theory, qualitative study of unstable aperiodic behavior in deterministic nonlinear dynamical systems, is dominant paradigm in the twenty first century. Fractal geometry, as an expressed form of chaos, now influences many areas such as architecture, art, music, economics, literature, etc. The purpose of this study is to analyze fractal geometry and fractal formative elements in architectural design. There are scaling, superimposition, distortion, deformation and repetition in the fractal form generator that can be applied to design concept and process in architecture. This study shows fractal geometry can be the architectural form creation method. Fractal geometry similar to nature's patterned order can be provided endless possibilities for design analysis and methodology in architecture. Therefore the further study of fractal geometry should progress synthetically through the basis of the study.

This paper proposes an advanced digital kwh-meter, which records voltage management data, load management data as well as the existing kwh data. This meter supports the requests from DRMS (Distribution Remote Management System) which include kwh meter reading, voltage management data reading, and load management data reading request, it can enhance greatly the economics of the existing remote meter reading system. Also it can improve highly the quality of power supplied to the electric customer by minimizing the voltage management cost and by enhancing the efficiency of load management.

This paper proposes a DRMS(Distribution Remote Management System) based on the advanced digital kwh-meter. The proposed URMS is designed so as to be able to collect the voltage management data, the load management data as well as the used kwh data from advanced kwh-meter remotelly. It makes the integrated management of distribution system possible and enhances highly the economics of the existing remote meter-reading system based on the only used kwh-data. Also it can improve highly the quality of power supplied to the electric customer by minimizing the volt age management cost and by enhancing the efficiency of load management.

This paper develops an ADWHM(Advanced Digital Watt Hour Meter) based on RISK type'8bit micro-controller, which has voltage management data recording function, load management data recording function as well as the existing watt-hour data recording data function. It can enhance greatly the economics of the existing remote meter reading system. Also it can improve highly the quality of power supplied to the electric customer by minimizing the voltage management cost and by enhancing the efficiency of load management.

Although the research on electronic commerce is plentiful, there is little empirical research related to Web-Based Shopping Systems (WBSS). This is especially so in global electronic commerce circumstances. WBSS are the fastest growing segment of digital economies and are perceived as driving forces of electronic commerce in terms of global markets and digital business. Using WBSS, organizations have a new chance of their business evolving successfully as global marketers. This paper develops a unified model to assess the diffusion of WBSS. Factors that impact WBSS diffusion are identified and analyzed as the basis for empirical testing. A set of propositions is developed that allows operationalization of the model. The ultimate goal is to provide the new research insights for the academic circles and the practical guidelines for organizations wishing to undertake WBSS.
