The techno-park built-up project of Korea had begun in order to support regional enterprises since 1997. The number of techno-parks increased from 6 in 1997 to 17 in 2009 with various enterprise supporting services such as a new enterprise breeding, pilot production, and education and training. By way of renewing regional innovation promoting system, revising technopark law, and starting second step techno-park project, techno-parks have become centers for regional technology innovation, and cultivation of regional technology-based companies. Alternative policies for the development of techno-park projects are as follows: revitalizing the network among enterprises, universities, research institutes, and government; strengthening the ability to draw up projects in nurturing regional industry; and the establishment of fixed channels to support SME in the region.

Competition in telecommunications field brings about change in attitudes toward technology development. It is no longer the case that technology development itself has merits but that technology development should be considered in terms of its economic concepts such as the cost-effectiveness concept. Techno-Economic study intend to incorporate the idea of economic efficiency into technology development and management so that economic potential of technologies is maximized. This paper categorizes the contents of techno-economic study in telecommunications and information technologies and suggests a framework of techno-economic study based on technology lifecycle and decision makers.

The importance of ventilation system is being emphasized by interest of indoor air quality. Especially, heat recovery ventilation system has attracted attention as most effective ventilation plan. Because it can reduce hazardous construction materials, indoor air pollutions, and also can reduce air conditioning energy cost. In heat recovery ventilator, the element core is the most important part. The element core is composed of liner and spacer. And liner and spacer are stacked alternately. On the Liner, heat and humidity transfer are made between supply and exhaust air. And spacer plays a role as a tunnel of exhaust and supply. In this study, we investigated and analyzed the efficiency of a heat recovery ventilator, when the spacer's properties are changed. As a result, difference spacer's properties affect an efficiency of heat recovery ventilator.

The purpose of the present work is to investigate the removal characteristics of positively charged filters for capturing negatively charged particles such as bacteria and virus in water. In order to reduce the pressure drop and increase the filtration efficiency, the filter media, modified by charge modifier having positive functional groups, is developed and evaluated. Improved liquid filters have been developed with the modified surface charge to capture and adsorb particles by electrokinetic interaction between the filter surface and particles contained in an aqueous liquid. The positively charged filter media is composed of glass fiber, cellulose and poly-ethylenimine resin for positively charging with the variation of volume ratio. The zeta potential value of the positively charged filter is +37.92 mV at the glass fiber and cellulose content ratio of 50 : 50 with resin content of 100%, while that of the PSL test particle is -23.5 mV at pH 7. The removal efficiency of the electro-positively charged filter is 98% for PSL particles of 0.11 ${\mu}m$, while that of the negatively charged filter is 7%. The positively charged filter media showed the potential to be an effective method for removing fine particles from the contaminated water for liquid filtration.

The importance of technical innovation is increasing gradually in accordance with the life cycle of technology being shortened and the convergence being accelerate. This thesis aims to present the Framework of Competency Model of Techno Leadership capable of utilizing in promoting R&D (Research and Development) Leaders systematically by the technology based enterprise. The characteristic of core behavior necessary for Techno Leaders has been sorted out through the literature investigation and the analysis course of meaning, etc., the competency model of Techno Leadership has been deducted by analyzing the relation with MOT (Management of Technology) capacity being common skill of task necessary for Techno Leaders and the characteristic of behavior based on this through the questionnaire survey. The possibility of application in the field as well has been verified by applying the developed competency model in the actual field of enterprise. The competency model of techno Leadership developed in this research may be utilized in the direction establishment for the promotion of Techno Leadership in the enterprise or laboratory, especially, if would be effective to self-diagnose the core competency necessary for R&D manpower to be grown as the Techno leader in the IT oriented enterprise and to establish the improvement direction.
