The purpose of this report is to investigate the electroacupuncture effect on the cholinergic neuronal activation in the hippocampal CA1 section. The electroacupuncture was performed on S36 of white rats and its consequencies were investigated by immunohistochemical method. Hippocampal CA1 sections of Sprague Dawley white male rats electroacupunctured on S36 at 20㎐ and 100㎐ are stained by cresyl violet to show that the values of 100㎐ and 20㎐ group increased significantly compared to sham group's one. Especially, 100㎐ group shows stronger neuronal activation compared to 20㎐ group. Induction of AChE, a neurotransmitter, in hippocampal CA1 is increased significantly in 100㎐ and 20㎐ group compared to sham group. Especially 20㎐ group shows higher AChE immunoreaction than 100㎐ does, although it wasn't significant enough. Induction of NGF(Nerve Growth Factor) in hippocampal CA1 sections was observed higher in 20㎐ and 100㎐ group than in sham group. Especially, 20㎐ group shows higher NGF immunoreaction compared to 100㎐. The facts above indicate that the eletroacupucture is effect to the cholinergic neuronal activation of hippocampus induced by focal ischemia.

This study is to make good acoustic environment around Gwang-ju riverside and performed survey and measurement of soundscape. The survey was focused on the types of sound producing. The results of measurement and analysis are as follows: 1) The types of sound at reverside were twenty and the Leq(equivalent noise level) was ranging from 50 dB(A) to 76 dB(A). The dominant sound was road traffic noise. 2) In the upperstream and the downstream, the sound of wind, bird and water was observed. 3) In the inner city, the water sound was produced by the difference of the height of the weir to mask the road traffic noise.

The researches classifying the artificial flaws in welding parts are performed using the pattern recognition technology. For this purpose the signal pattern recognition package including user defined function is developed and the total procedure is made up the digital signal processing, feature extraction, feature selection, classfier design. Specially it is composed with and discussed using the ststistical classfier such as the linear discriminant function classfier, the empirical Bayesian classfier.

Objective: To report the case of a patient suffering from Broca’s aphasia after cerebral infarction, which was improved by Korean medical treatments, especially five-element acupuncture.Methods: To relievesymptoms, Korean medicine treatments such as acupuncture, moxibustion, and herb medication were performed. To evaluate the effect of the treatments, articulation accuracy, vowel accuracy, and the sequential motion rate of articulator were checked.Result: After treatments for 28 days, the symptoms were improved.Conclusion: This report suggests that five-element acupuncture can be effectively used for patients with Broca’s aphasia after cerebral infarction.

In this study, we report that an electrical properties of OLEDs was investigated by the surface etching method of ITO Layer. The electrical properties of OLEDs was measured by IVL and optical properties by EL spectrum. The fundamental structure of OLEDs was ITO anode/TPD(400$\breve{A}$)/$Alq_3(600\breve{A})$/LiF(5$\breve{A}$)/Al(1200$\breve{A}$) cathode. The threshold voltage was low value according to the low resistance of surface. The luminance was increased by decreased surface resistance.

최근 영화, 광고 그리고 증강현실과 혼합현실 등 다양한 분야에서 실제 영상에 가상의 객체를 합성하는 기법이 자주 사용되고 있다. 보다 사실적인 합성 결과를 생성하기 위해서는 실제 배경영상의 광원정보를 그대로 적용해야 한다. 이러한 실 세계의 광원 정보를 이용하기 위해서는 HDR(High Dynamic Range) 영상을 생성해야 한다. 일반적으로 HDR 영상을 생성하기 위해서는 고가의 HDR 카메라를 사용하거나 LDR(Low Dynamic Range) 카메라를 사용하여 노출 시간을 달리한 일련의 LDR 영상을 촬영하여 이를 기반으로 HDR 영상을 생성해야 한다. 본 논문에서는 이러한 단점을 보완하기 위해 한 장의 LDR 환경 맵을 HDR 환경 맵으로 복원하는 방법에 대해 제안한다. 제안하는 방법을 통해 LDR 환경 맵을 HDR 환경 맵으로 복원할 수 있으며 결과에서 볼 수 있듯이 HDR 영상을 이용했을 때와 유사한 렌더링 결과를 생성할 수 있다.

This study was conducted to improve the postharvest storage techniques of managing and storing seeds, to test qualities and viabilities of the seeds and to examine the germination rate and the protein expression of Achyranthes japonica Nakai. The seeds collected from different areas of Je-Cheon and Gwang-Ju were stored with different temperatures and durations. Two plant growth regulators and two seed priming were treated to investigate their effect on the germination rates and the days required for germination. The weight of one hundred seed collected in Gwang-Ju was heavier than those in Je-Cheon. Seed length collected in Gwang-Ju was also longer about 5.12 mm than those in Je-Cheon about 4.90 mm and seed width was longer in Gwang-Ju than those in Je-Cheon. The rates of seed germination in two different collection areas were higher about 2.9 to 13.0% in Gwang-Ju compared to those in Je-Cheon. Comparing its rates with the storing temperatures and durations, they were not clearly different in between $4^{\circ}C$ and $25^{\circ}C$ and they also were gradually decreased with getting longer storing durations. The germination rates treated by plant growth regulators were higher with $GA_3$ than those with Kinetin. The highest seed germination rate was appeared at 50 ppm of $GA_3$. Comparing its rates with different seed priming, they were relatively higher with $KNO_3$ than those with PEG6000. In protein expression patterns between before the germinating and after the germinating of seeds, more and clear bands were appeared in the seed after the germination compared to those before the germination of seeds, especially 10 ~ 20 kDa. These results showing more and clear bands were more clearly appeared in Gwang-Ju compared to Je-Cheon. Comparing the protein expression with plant growth regulators and seed primings, $GA_3$ was better expression than those with Kinetin and $KNO_3$ was better than those with PEG6000. More and clear bands were closely related to the germination rates of seeds and more detailed studies would be required.

In this paper we have developed metadata system in order to utilize and refer to ICT educational resources which stand on the basis of standard international metadata " DC Core Education" by analyzing into the time input resources during each lessons. This metadata system makes addition metadata elements(introduction, development, review) in the flow of a general lesson to many ICT educational resources and high quality educational information in the web. It means elementary school teachers feel easy and convenient by offering systematically interface and unify reference. The system could expect to willing to help effectively lessons with ICT.
