  • In this study, the characteristics of large area internal linear ICP sources of $1,020mm{\times}920mm$ (substrate area is $880mm{\times}660mm$) were investigated using a multiple linear antennas with U-type parallel connection. Using the multiple linear antennas with U-type parallel connection, a high plasma density of $2{\times}10^{11}/cm^3$ and a high power transfer efficiency of about 88% could be obtained at 5kW of RF power and with 20mTorr Ar. A low plasma potential of less than 26V and a low electron temperature of $2.6{\sim}3.2eV$ could be also obtained. The measured plasma uniformity on the substrate size of 4th generation $(880mm{\times}660mm)$ was about 4%, therefore, it is believed that the multiple linear antennas with U-type parallel connection can be successfully applicable to the large area flat panel display processing.

  • 사람의 혈액 내의 단핵구 U937을 모델시스템으로 이용하여 옻추출물 처리에 의해 발현이 조절되는 특정 유전자를 탐색하였다. DDRT-PCR을 이용하여 옻 추출물 처리 시 발현이 감소되는 클론을 하나 얻을 수 있었으며 이를 클로닝하고 염기서열 분석을 실시하였다. 그 결과 얻어진 유전자는 H2A histone family의 member Z와 100% 유사성이 있는 것으로 나타났다. 이 단백질은 특정 조건 하에서 특정한 유전자 발현을 증가시키는 역할을 하는 것으로 보고되고 있으나, 보다 정확한 작용기작을 알아내기 위해서는 유전자 관계 파악을 위하여 향후 계속적인 연구가 필요함을 알 수 있었다.

  • In this paper, we propose a new method for measuring image sticking of an OLED display using a human visual test. We determined that the perceptual image sticking threshold is 2% of luminance difference at 200 nits and 1% at 100 nits, respectively. Color shift must also be considered when evaluating image sticking, as a ${\Delta}$(u', v') shift of just over 0.002 can be recognized regardless of background brightness. Perception of image sticking is affected by the background level, test pattern, and ambient illumination conditions. The evaluation standard must consider both luminance variation and color shift simultaneously.

  • High performance p-ch poly-Si TFTs with excellent stability were developed. By using a frequency doubled DPSS CW laser, the a-Si on glass could be crystallized into one dimensional single crystalline silicon named as a sequential lateral crystallization (SLC) region. We fabricated p-ch TFTs on SLC region and the typical characteristic values of the TFTs were $u_{fe}$ = 180 $cm^2$/Vs, $V_{th}$ = -3 V, S.S. = 0.5 V/dec, and $I_{off}$ = 1 pA/um@ $V_d$ = -10V. It is found that the TFTs are very stable after bias stresses such as negative and positive gate biases, hot carrier bias and high current bias. These results indicate that the poly-Si in SLC region is suitable for system on glass (SOG) application.

  • Human error has brought about accidents more than 50% in system of a large size and complicated expecially in nuclear power plants(NPPs). The technology of Man Machine Interface(MMI) has been changed to the digitalized controls employing computer-based technology. According to this trend. the human factors guidelines are becoming main issue for reliable supports to digitalized information displays. However. the existing human factors guidelines is not enough for advanced information display on NPPs. The purpose of this research is to develop the reliable design and evaluation guidelines for advanced information display in main control room (MCR) of NPPs. In this study. the various general human factors guidelines concerning information display on CRT are integrated on data base management system. unified based on the integration rules. and applied in computer based procedures. The use of the integrated guidelines are expected to evaluate the existing information display on MCR in NPPs from the human factors point of view.

  • 본 논문의 연구배경은 플로우 이론을 적용한 u-융합정보시스템이 관광객의 만족도 측정이 부족하기 때문에 연구를 시작하게 되었다. 본 연구의 목적 및 연구 방법은 다음과 같다. 첫째는 플로우 관계정보 표시형식 알고리즘 제안이다. 둘째는 이 알고리즘과 플로우 이론을 접목시켜 콘텐츠 정보품질과 관광객의 성격 유형에 따라 패턴 알고리즘을 생성한 것이다. 본 연구의 기대효과는 플로우 관계정보 표시형식과 관광객의 성격 유형에 따라 패턴 알고리즘을 생성함으로서 u-융합정보시스템의 성공요인을 도출한 것이다. 본 논문의 한계성은 한 지역을 한정적으로 하였으며 데이터의 부족과 소규모 지역으로 객관성이 떨어진다. 추후, 다른 관광지에 제시하는 방법 적용 후, 분석을 통해 효용성을 평가할 필요가 있다. 향후 과제는 전문가 집단의 데이터 보완이 필요하고 여러 지역의 객관성이 보완되어야 할 것이다.

  • Many well-known pixel compensation circuits have been applied to control TFT $V_{th}$ variations on small size AMOLED panels. For large (>30-inch) AMOLEDs, luminance and color uniformity are affected by TFT variations, but also by ELVDD IR drop and cavity non-uniformity which are not easily compensated by in-pixel circuits. AMOLED panels may also suffer from manufacturing-induced mura. An external compensation method based on optical measurements is proposed and applied to large AMOLED panels. It improves luminance uniformity by up to 95% at 200nits and color uniformity by up to 99% (${\Delta}$u'v' <0.004) on large AMOLED panels, and provides-increased margin against processinduced mura.
