  • This study is performed to examine the relationships between trust and antecedents in cyberspace. Trust is the major control system in cyberspace. Different time, different spaces, different cultures, indistinct boundaries, flexible structure, separation of information from matters, cybernetics, difficulty of control are differential characteristics between cyberspace and physical space. Providing fit information, use of effective electronic channels, previous trust management, feedback system about output, flexible culture, self-regulation, off-line meeting, providing information about tasks and roles, ability, and justice are supposed to have effects on trust in cyberspace. By electronic mediated systems, the company will have more business opportunity. But trust will be conditional factors of expanding business in cyberspace.

  • In this letter, we study the impact of single event upsets (SEUs) in space or defense electronic systems which use memory devices such as EEPROM, and SRAM. We built a microcontroller test board to measure the effects of protons on electronic devices at various radiation levels. We tested radiation hardening at beam current, and energy levels, measured the phenomenon of SEUs, and addressed possible reasons for SEUs.

  • 레이저 유기 압력 펄스법을 이용하여 가교폴리에틸렌필름과 전력케이블의 공간전하의 성질을 정량적으로 연구하여 다음과 같은 결론을 얻었다. 잔류가교제를 갖는 XLPE에서는 음극으로부터 현저한 전자주입이 나타나고 시료전체에 걸쳐 부의 공간 전하가 형성되었으며 음극으로 부터의 전자 주입은 전계상승에 따라 증가 하였다. XLPE 전력 케이블에서는 잔류가교제가 이온화하여 생긴 정 및 부의 헤테로 공간 전하가 음극 및 양극 부근에 형성되었다.

  • The effects of low molecular weight components of LDPE and sample molding condition were investigated to find the orgins for heterocharge in LDPE without any addtives. Low molecular weight chains of LDPE encourages the formation of heterocharge by being charged and migrating the counter electrode. The formation of heteroohage in LDPE was also effected by sample preparation process and the kind of a moling film. When PET film is used as a molding layer, the carbonyl, which may lead to increase the heterocharge, formed at surface of LDPE.

  • The behavior of charged particle in dielectrics have a many effects on characteristics of the insulating materials. In this paper, numerical analysis method by hopping model was investigated application of TSC. As the results, there was a difference between characteristics of TSC by dipole polarization. Physical constant of movable ion corresponding to the experimental results was evaluated and also. Numerical calculations of unsaturated TSC and I-V characteristics were carried out by was of hopping model.

  • In this paper, the eigenvalue sensitivity analysis algorithm in discrete systems by the RCF method are presented and applied to the power system including TCSC. The RCF analysis method enabled to precisely calculate eigenvalue sensitivity coefficients of dominant oscillation modes after periodic switching operations. These simulation results are very different from those of the conventional continuous system analysis method such as the state space equation method

  • Recently, there has been much focus on the controlled alignment and patterning process of nanowires for nanoelectronic devices. A simple and effective method for patterning of highly aligned nanowires using a microcontact printing technique is demonstrated. In this method, nanowires are first directionally aligned by contact printing, following which line and space micropatterns of nanowire arrays are accomplished by microcontact printing with a micro patterned NOA mold.

  • YSe1.83 was synthesized by vapor transport technique and its crystal structure was determined. The structure was isostructure of LaTe2-x, which was layered structure consisting of two-atom thick layers of YSe with distorted NaCl-type structure and one-atom thick layer of Se. The substructure of YSe1.83 was tetragonal with space group of P4/nmm and a=4.011(2) and c=8.261(3) Å with final R/Rw=6.4/6.9 %. The superstructure with asuper=2a, bsuper=6b and csuper=2c was found. The measurements of electronic and magnetic properties of this compound indicate that it is an electronic insulator and diamagnet.

  • A skin tissue system is considered, whose configuration is electrically modelled by a layer over the infinite half space. The problem is to estimate the layer\`s thickness and respective conductivity from the measured impedance between the electrodes placed on the skin surface. A simulation is taken place as the optimization problem which is to minimize the norm between the \"measured\" and the solution for the assumed parameters.arameters.
