To improve the luminance and efficiency of AC PDP, the effects of a square pulse applied to the address electrode during a sustain-period is investigated. Through this experiment, we confirmed the improvement of luminance and efficiency. We performed the temporal behavior measurement for the light emitted from AC PDP at floating state of the address electrode and at various auxiliary voltages (including ground state) applied to the address electrode using the scanned point detecting system. In the case of using an auxiliary voltage pulse, emission starts at the inner edges of the anode and cathode simultaneously. Also, we obtained the larger two discharge volumes compared with the normal sustain discharge where address electrode is floated.

We measured 3-dimensional temporal behavior of the light emitted from AC plasma display panel(PDP) at various auxiliary voltage pulse width supplied to the address electrode in sustain period using scanned point detecting system. In the case of applying an auxiliary address voltage pulse, the light emission starts at the inner edges of the cathode so the larger discharge volume toward address electrode can be obtained compared with the normal sustain discharge. Especially, when the auxiliary voltage pulse width is the $2{\mu}s$, the maximum luminance and long emission time can be obtained.

A new distribution of Scutellaria guilielmii A. Gray is discovered in Korea. This species was collected from seashores on Pyoseon-ri, Pyoseon-myeon, Seogwipo-si, Jeju-do. S. guilielmii is distinguished from other related Korean taxa of the genus by having broadly winged nutlets (fruits). Here, we provide a precise description, illustrations, key to the related taxa, and photographs of its habitat. The new Korean name is given as 'Nal-gae-gol-mu-kkot', considering the broadly winged nutlets (fruits). In addition, new habitats are likely to be discovered through plant biodiversity surveys of the southwestern coastal islands.

According to the bone-standard measuring, the length between the elbow and the wrist has the span of 1.25 cheoks whereas it has the span of 1.2 cheoks or 1.2 cheoks today, the breadth of the chest has the span of 9.5 chons whereas it has the span of 8 chons today, and the length from celestial pivot to transverse bone has the span of 6.5 chons whereas it has the span of 5 chons, and the length from free rib region to thigh pivot has the span of 6 chons whereas it has the span of 9 chons today. It is said that all of the acupuncture points are correctly prescribed by the bone-standard measuring irrespective of men and women of all ages, fat and lean, and whether large or small in height. This lies at the root of the selecting acupuncture points. The bone standard in Spiritual Pivot and that in common use at present have a little difference and the bone standard of today is based upon A-B Classic. Spiritual Pivot named as Acupuncture Classic was in good preservation until the mid-eleventh century, but the book lost a lot in contents was the incomplete edition. In the 8th year of the king Cheoljong's reign of the North Song Dynasty in 1093, though the nine-volume Spiritual Pivot drafted from the Goryo Dynasty was published, the book was wanting in consistency. While on the other, I think that A-B Classic which has been in a state of perfection had a great influence on the healers of the day.

In this paper, we measured 3-dimensional temporal behavior of the light emitted from discharge cell of plasma display panel(PDP) as a function of the pressure using the scanned point detecting system. The detected light signal through the PM tube is sent on the oscilloscope and oscilloscope which is connected to PC with GPIB. The whole system is controlled by a PC. From the temporal behavior results, we could analyze the discharge behavior of panel with Ne-Xe(4%) mixing gas and 300torr, 400torr, 500torr pressure. The top view of panel shows that the discharge moves from inner edge of cathode electrode to outer cathode electrode forming arc type. At the 300torr, initial emission time is very fast. The side view of panel shows that the light is detected up to $150{\mu}m$ height of barrier rib. In the panel of 300torr, emission distribution is wider than the others.

To protect the watermelon against soil-borne pathogens, we are currently producing disease-resistant transgenic root stock for the growth of watermelon, A defensin gene (J1-1) from Capsicum annum, a ACC deaminase gene from Pseudomonas syringae, a galactinol synthase (CsGolS) gene from Cucumis sativus, and a WRKY (CvWRKY2) gene from Citullus vulgaris were used as transgenes for disease resistance. The gene were transformed into a inbred line (6-2-2) of watermelon, Kong-dae watermelon and a inbred line (GO702S) of gourd, respectively, by Agrobacterium-mediated transformation. Putative transgenic plants were selected in medium containing 100mg/L kanamycin, and then integration of the genes into the genomic DNA were demonstrated by PCR analysis. Successful integration of the gene in regenerated plants was also confirmed by PCR (Figf 1), genomic Southern blot (Fig 2), RT-PCR (Fig 3), and Northern blot analysis(Fig 4). Several T1 lines having different transgene were produced, and disease resistance of the T1 lines are under estimation.

Objectives : In Huangdineijing(黃帝內經), there are many uncertain terms to express body structures, for example, Yuk(肉, flesh). The purpose of this study is to define the meaning of Yuk(肉, flesh) and relevant terminologies. Methods : To define the meaning and origin of Yuk(肉) character and relevant terminologies, examples in Huangdineijing(黃帝內經), Seolmunhaeja(說文解字) and other important references are investigated. Results : Yuk(肉) character has etymologically meant meat, and afterwards it has got meaning of flesh. In the main two terms derived from Yuk, Giyuk(肌肉) means flesh, and Bunyuk(分肉) means muscles in anatomical knowledges. Also Yuk has been the most important etymological word that means body, among the five parts of body[五體], Geun(筋, tedndon and ligament), Maek(脈, blood vessel), Yuk(肉 flesh), Pi(皮, skin) and Gol(骨, bone) to contribute to making basic meanings of those characters. Conclusions : It is necessary to make clear the definitions of many Korean medical terminologies especially in anatomical knowledges to be helpful for systematic management of terminologies.

The number of grain is determined based on Poisson distribution in respectively different active channel and it is converted to grain size which affects to the mobility and threshold voltage. the acquired data is applied to the SPICE for observing the variation of I-V characteristic with several channel lengths. we can confirm the effect on device.

Ashing of photoresist was investigated in dielectric barrier discharges in atmospheric pressure by changing applied voltage, frequency, flow rate. we analyzed the plasma by Optical Emission Spectroscopy(OES) to monitor the variation of active oxygen species. Another new peaks of oxygen radical is observed by addition of argon gas. This may explain the increase in ashing rate with argon addition. With the results of Optical Emission Spectroscopy(OES), we can find the optimized ashing conditions. MIS capacitor for monitoring charging damage by the plasma was also studied. The results suggest the dielectric barrier discharges(DBD) can be an efficient, alternative Plasma source for general surface processing.

Objective : The purpose of this study is to find out the effects of Dorsiflexion of foot & great toe of Dong-si acupuncture therapy for the patients with lumbago. Methods : A retrospective study has been carried out for 20 cases of lumbago patients who visited Cheongju Oriental Medical Hospital from January 1, 2002 to June 30, 2002. We have treated tem with acupuncture treatment of Dong-si acupuncture points(Yeong-gol and Dae-baek) and taken measurements with a Hand Grip Meter. Results : 1. There was no siginificance difference between the average values of the whole group and each groups divided by age before and after Dong-si acupuncture therapy. 2. The correlation of measured values before and after Dong-si acupuncture therapy was as much as 0.849, which suggests that the patients with higher value before the therapy also had higher value after the therapy. 3. The average value after Dong-si acupuncture therapy was higher than the average value before the therapy by $1.9625{\pm}.8440$, which suggests the therapeutic significance. Conclusion : The Dong-si acupuncture therapy is effective therapy of Dorsiflexion of foot & great toe.
