An optical sensor was developed to detect nanoparticles, turbid materials and microorganisms in water simultaneously. Three different light sources like UV-LED, NIR-LED and laser diode have been employed to develop the optical sensor based on the scattering light and fluorescence light. The sensor system has high selectivity and sensitivity, that it can be used to monitor the quality of drinking water.

The purpose of this study contains evaluation of techno-cyber fashion, specifically in the area of dancing costume which symbolize the stage performing art of techno-cyber fashion's formative elements. The way of study is to make foundation with the theory and picture backgrounds to analyze the fashion trends and finally produce symbolic dance costume which applies modern dance stage costume design to techno-cyber elements. The 'Adieu 1999' is the modern dance work contains social mood in retrospect of 20 century and prepare 21 century. To make design of dance costume, apply the simple geometrical pattern design which utilize techno-cyber element like hi-tech fabrics, see-through and image of band and finally produce costume both 20 and 21 century.

Application of ceramics, carbide, ferrite has grown considerably due to significant improvement in their mechanical properties such as light weight chemical stability super wear resistance and electronical. Despite these character, the use of hi-tech material has not increased because of poor machinability. The method of using of metal bond wheel was proposed. But it is difficult that metal bond wheel can be dressed. Recently, the technology of in-process electrolytic dressing is developed to solve this problem. This method need wheel for electrolytic dressing, power supply and electrolyte. But development of wheel for electrolytic dressing is the most need. The aim of this study is development of wheel for electrolytic and appraisement of CIB-diamond lapping wheel

This research examines the characteristics of incubating organizations of hi-tech ventures in the information technology industry. In particular, it attempts to investigate incubating conditions under which entrepreneurs obtain their management abilities and market information, locate business partners and prepare the prototypes of their new products. For the empirical test, three incubator organizations, two universities (Seoul National University and Korea Advanced Institute of Science and Technology ) and a government research institute (ETRI: Electronics and Telecommunications Research Institute) are compared in terms of incubating conditions. It is found that two universities are not different in terms of lab members' demographic characteristics and their attitude towards venture creation. However, the entrepreneurial environments of incubator organizations are different between the universities and ETRI. The universities have more favorable environments than ETRI in terms of management know-how or capabilities, while ETRI has more favorable environments than the universities in terms of the information about markets, distribution channels or customers. The results of this study would provide many policy implementations to administrators of incubator organizations as well as government policy-makers in making effective venture-creation policies.

In this paper, an automatic welding carriage is developed by wireless communication. In the developed system, a data transmission of a automatic welding line tracking is adopted by RF communication. Additional, a welding condition of the automatic welding carriage IS displayed by microprocessor. Therefore, the developed system can overcome the restriction of an operating distance and perform an accurate transmission of the control signal.
