In this paper, we proposed a simple method of decreasing the off current generated by degradation for improve the electrical characteristics such as mobility and on/off current ratio by making the line patterns on the pentacene surface between the electrodes using atomic force microscope (AFM) lithography.

This study examined and analyzed the women's jeogoris in the Seoul Gwangjang Market and Busan Jin Market. They study explored the items to look into the current state of the Jeogori patterns, as well as investigate the flat pattern jeogoris, including its source and aspects of change. Korean women's body figure has become more westernized, and the purpose of this study is to investigate the effects of this change on the traditional jeogoris. We hope to gather valuable data, which can be used to propose a new direction for designing hanbok in the future. The study methods are as follows: First, the types of jeogori patterns were examined. Second, the current state of jeogori patterns in the Seoul Gwangjang market and Jin market in Busan were analyzed to look into how the patterns have transitioned. And lastly, the reason for the origination of the flat pattern jeogori and the type of changes will be examined. Current study results show that two pattern types are being used: the flat composition jeogori and the flat pattern jeogori. Surveys show that more than 90 percent of the jeogoris in the Seoul Gwangjang Market are of the flat composition pattern variety, while more than 90 percent of jeogoris in the Busan Jin Market are of the flat pattern variety. In 1998, western-style dress designers in Busan introduced the flat pattern jeogoris, which were used to get rid of the wrinkles caused by the extra space, into the market after the financial crisis period in Korea, as a way to revitalize the market. This new pattern was popular among tea aficionados and traditional Korean musicians. It was exposed to the public via different mediums, such as TV programs, magazines, and brochures. Busan was the first to be exposed, and then it spread to Seoul. It also seems that the reduction of production cost caused the increase of the flat pattern jeogori.

In this study, the rise throughput and the stability in fabrication of device can be obtained by applying of CMP process to STI structure in 0.l8um semiconductor device. Through reverse moat pattern process, reduced moat density at high moat density, STI CMP process with low selectivity could be to fit polish uniformity between low moat density and high moat density. Because this reason, in-situ motor current end point detection method is not fit to the current EPD technology with the reverse moat pattern. But we use HSS without reverse moat pattern on STI CMP and take end point current sensing signal.[1] To analyze sensing signal and test extracted signal, we can to adjust wafer difference within $110{\AA}$.

Studies on the flow pattern due to reclamation in the Myunggi-Nocksan region are carried out based on field observations and numerical experiments. Serial time series measurement of current, temperature and salinity were conducted for 1 tidal period at intervals of 1 hour from surface to bottom on station located at 128.deg. 54' 44" E, 35.deg. 01' 04" N in April and June 1992. Surface current opposite to the subsurface current causes turbulent mixing to make homogeneous salinity pattern in vertical section. Reclamation has little effect on the wave pattern and flow patterns are also nearly similar except on the nearby region of reclamation where flow speed somewhat weakened.

A new current controlled PWM technique with NPC structure is proposed in this paper. A current controlled PWM technique with neutral-point-clamped pulse-width modulation inverter composed of main switching devices which operates as switch for PWM and auxiliary switching devices to clamp the output terminal potential to the neutral point potential is described. The proposed current controller has a first and second current band. The switching pattern will be made by the first current band. According to the second current band, the output state of the switching pattern is changed into positive and negative state. This inverter output contains less harmonic content and lower switching frequency than that of conventional current controlled PWM technique at the same current limit. Two inverters are compared analytically and the performance is investigated by the computer simulation.

Objectives : The aim of this study is to summarise pattern-identification of shoulder pain based on the classics of oriental medicine, current literature and domestic papers. Methods : The materials selected were sourced from the classics of oriental medicine, current literature and domestic papers which contained data related to pattern-identification of shoulder pain. The pattern-identifications were compared to determine the similarities, and these were classified. Results : Thirty-five studies were reviewed, and thirty-seven pattern-identifications were collated. These were classified into the following groups: wind-cold-dampness group(n = 8), blood stasis group(n = 3), phlegm group(n = 7), dual deficiency of Qi and blood group(n = 4), deficiency cold group(n = 2), liver-kidney deficiency group(n = 1) and meridian-collateral group(n = 12). Conclusions : On the basis of the classification of pattern-identifications, two groups of pattern-identifications for shoulder pain were suggested. The first group included the pattern-identification associated with a disease-cause, which included the wind-cold-dampness pattern(風寒濕型), blood stasis pattern(瘀血型), phlegm pattern(痰飮型), Qi-blood deficiency pattern(氣血兩虛型), deficiency cold pattern(虛寒型), and liver-kidney deficiency pattern(肝腎虧損型). The second included the pattern-identification associated with the meridian-collateral, which included the hand greater Yin meridian pattern(手太陰經型), hand Yang brightness meridian pattern(手陽明經型), hand lesser Yin meridian pattern(手少陰經型), hand greater Yang meridian pattern(手太陽經型), hand reverting Yin meridian pattern(手厥陰經型), hand lesser Yang meridian pattern(手少陽經型), and foot greater Yang meridian pattern(足太陽經型).

This paper presents an advanced abnormal over-current protection with $SuperFET^{(R)}$ 800V MOSFET in Flyback converter. In advanced abnormal over-current protection, digital pattern generator is proposed to detect a steep di/dt current condition when secondary rectifier diode or the transformer is shorted. If current sensing signal is larger than current limit during consecutive switching cycle, Gate signal will be stopped for 7 internal switching periods. If the abnormal over-current maintains pattern, the controller goes into protection mode. The Advanced over-current protection has been implemented in a 0.35um BCDMOS process (ON Semiconductor process).

In order to clarify the seasonal variation of the residual current and the material transportation process in Hiroshima Bay, JAPAN, the real-time simulation of residual current and particle tracking by using the Euler-Lagrange model were carried out. The calculated tidal current, water temperature, and salinity showed good agreement with the observed ones. The residual currents showed a southward flow pattern at the upper layer, and a northward flow pattern at the lower layer. The flow structure of the residual current in Hiroshima Bay is an estuarine circulation affected by density flow and wind driven current. The residual current plays an important role of material transportation in the bay.

Current distributions according to electrode patterns in vertical structured InGaN/GaN LED (light emitting diode) were investigated quantitatively by utilizing three dimensional electrical circuit modeling method. The uniformity of the injected current density in the active layer was compared among different electrode patterns. It was found that the current uniformity was greatly dependent on the electrode pattern in vertical InGaN/GaN LEDs.
