  • The characteristics of interface layer and the effect of mole fraction of inlet gas mixture($B_2H_6/H_2/N_2/TiCl_4$) on the microstructure of Ti(B,N) films were studied by microwave plasma hot filament CVD process. Ti(B,N) films were deposited on a substrate(STD-61) to develop a high performance of resistance wear coating tool. Ti(B,N) films were obtained at a gas pressure of 1 torr, bias voltage of 300 V and substrate temperature of $480^{\circ}C$ in $B_2H_6/H_2/N_2/TiCl_4$gas system. It was found that TiN, $TiB_2$, TiB and hexagonal boron nitride(h-BN) phases exist in thin layer on the STD-61.

  • 본 연구는 정보탐색 노력에 대해 정보의 모호성으로 인해 발생하는 불확실성의 지각, 불협화음의 인지, 그리고 관여정도가 작용하게 되는 역할에 대해 살펴보았다. 본 연구가설의 검증을 위해 정보탐색의 경험이 있는 155명의 설문을 활용하였다. 정보탐색 노력에 영향을 미치는 요인들로 정보의 모호성으로 인한 지각된 불확실성수준, 불협화음의 인지, 그리고 관여정도로 파악되었다. 본 연구의 결과를 통해 정보의 모호성으로 인해 나타나는 정보탐색 과정에 이러한 요인들이 어떠한 관계를 갖고 있으며 그 차이점을 제시하여 정보탐색 행동을 이해하는데 새로운 방향을 제시하였다고 본다.

  • Recently, e-business has very much attention in the management fields because it is expected to fundamentally change the way many business compete. Business that don't understand the changes and that can't change their operating model in time will be at a disadvantage. Information technology infrastructure and its management are key components of e-business The purpose of this study was to investigate the effects of information technology infrastructure and its management to the type of information systems used and the use of e-business. A total of 56 Korean firms responded to the survey instrument. There was indirect effect to the use of e-business from the information technology structure via communication capacity and direct effect from management type. The study also found that firms with less centralized forms of information technology were more frequent users of e-business, Firms that have more freedom in information technology decision making tended to be users of the new technology and take advantage opportunities that exits on the information technology.

  • The auther measured exothermic tempreature of the 5 kinds of direct resins during polymerization. Direct resins were mixed into the rubber cup(550-600㎣ in volume) with grass rod at room temperature (23.6℃) for 30 seconds and thermometer was placed approximately at the geometric center of the resin mass in the rubber cup. Polymer-monomer ratio was determined by instruction of the packages. The results were as follows. 1) The heat generated during polymerization was under 47.3℃. 2) The time at which the highest temperature is reached during polymerization was within 20.5 minutes. 3) Slow curing resins produced lower heat than quick curing resins and quick curing resins presented higher temperature than slow curing resins. 4) The highest temperature was sustained momentarily.

  • A driver's feelings of transmission serve as a basis to judge not only the transmission but also the entire automobile that he or she drives. The importance of transmission feelings is increasing daily because of driver's desire for increased torque and other improved functions. In order to accommodate such desire of drivers, new friction materials have been developed. The study in this report compared the affects of such materials and the force for transmission theoretically and empirically. By doing so, the study attempted to establish basic references for computation of capacity and other factors to be determined at the time of design of synchronizer system.

  • The antifuse is a semi-permanent memory device like a ROM which shows the open or short state, and a switch device connecting logic blocks selectively in FPGA. In addition, the antifuse has been used as a logic device to troubleshoot defective memory cells arising from SDRAM processing. In this study, we have fabricated ONO antifuses consisted of PIP structure. The antifuse shows a high resistance more than several G Ω in the normal state, and shows a low resistance less than 500 Ω after program. The program resistance variation according to temperature shows the very stable value of $\pm$20 Ω. At this time, its program voltage shows 6.7∼7.2 V and the program is performed within 1 second. Therefore this result shows that the PIP antifuse is a very stable and programmable logic device.
