본 논문에서는 차량번호판 인식시스템의 성능을 최대화 하기 위해 충격잡음과 가우시안 잡음으로 인해 손상된 입력영상을 중간값 필터와 형태학 필터를 이용하여 개선하는 방법을 제안하였다. 실험에서 각 필터를 적용한 결과를 PSNR을 통하여 비교하였고, 인식결과와 학습 기대값 사이의 MSE를 측정함으로서 인식시스템의 성능을 비교하였다. 실험결과 손상된 차량번호판의 입력영상은 최대 3.7dB까지 개선되었으며, 인식시스템의 성능 평균 MSE는 약 1.84×10-3 로 원활한 인식이 이루어짐을 확인하였다. In the paper we propose a method which makes the performances of the vehicles plate recognition system better for the impulse or gaussian contaminated images using the median and morphological filters. Comparing the PSNR and MSE of the experimental results, PSNR has been improved to 3.7dB maximally and the average MSE is 1.84 ×10-3.

인터넷과 전자산업기술의 발달로 영상의 획득과 처리를 동시에 수행하는 실시간 처리 기술이 용이하게 되었다. 본 논문에서는 심장혈관의 위치, 모양, 크기 등의 정보를 우리에게 알려주는 의용 영상의 에지검출에 Genesis 보드와 이를 제어하는 MIL 패키지를 사용하여 실시간 개념을 적용한 실험을 구현해 보았으며, 획득한 영상에 적용한 마스크의 크기에 따른 영상처리 속도와 실시간 개념에 맞는 최대 제한 속도를 조사해 보았다. The development of electronics and internet technologies is enable to perform of real-time image acquisition, processing, and transmission almost simultaneously. In the paper, real-time edge detection of the medical coronary angiograms image was accomplished by making use of the Genesis H/W board and the MIL(Matrox Image Library) S/W package. The comparison of the processing time for the various mask to detect the edges of the given image shows the determination about the limited mask size under the real-time processing environment.

Involvement of central nervous system is a well-known compication in uremic patients. However, development of acute extrapyramidal symptoms with bilateral basal ganglia involvement (acute basal ganglia syndrome), especially in non-diabetic hemodialysis patient is very rare. We report a case of acute basal ganglia syndrome in a non-diabetic hemodialysis patient. A 45-year-old man with autosomal dominant polycystic kidney disease (ADPKD) on chronic hemodialysis treatment for the last 4 years was admitted due to generalized myalgia. On admission, the patient was found to have rhabdomyolysis and intractable metabolic acidosis. Nine days after admission, he suddenly developed dysarthria, lateralizing ataxia, and bradykinesia. Brain MRI demonstrated low and high signals in bilateral basal ganglia and cerebellar vermis in T1-weighted and T2-weighted images, respectively. Intensified hemodialysis treatment combined with general supportive therapy resolved the severe metabolic acidosis and the neurologic manifestations gradually improved. Follow up brain CT scan taken 3 months later showed decreased size of initial low attenuation lesions in bilateral basal ganglia and cerebellar vermis. Although no definite pathophysiology is yet established, severe metabolic disorder is believed to play an important role in development of acute basal ganglia syndrome. Correction of metabolic acidosis and hypoglycemia in our patient lead to improvement in neurologic manifestations and organic brain lesions. Our case suggests that severe metabolic acidosis and hypoglycemia in uremic patient may act as risk factors for acute basal ganglia syndrome even in non-diabetic patient.

Analysis of Hydraulic Lift Force of a Fuel Assembly
Sim, Yoon-Sub,Oh, Dong-Seok,Hong, Soung-Dug,Kwon, Hyuk-Sung Korean Nuclear Society 1990 Nuclear Engineering and Technology Vol.22 No.2
The exact expression for the 1151 force on a fuel assembly in a reactor core is derived in terms of calculable hydraulic parameters. The relation for the lift force. pressure drop, buoyancy force, viscous force. and fuel assembly weight is discussed. Based on the derived exact expression. error analysis is made for a simple expression applying COBRA IV-i to a typical PWR fuel assembly. The error analysis revealed that the error of the simple expression consists of four terms and the overall error depends on the flow rate change direction, and its magnitude is about 1%.

An attempt was made to prepare having pyridine derivatives contained chitosan derivatives that is suitable for N-substituted as thiobenzoic acid contained nicotinic acid and pyridinium derivatives side chain form. Those chitosan derivatives showed high selective adsorption abilities in order of Pb>Cd>Cu>Zn>Hg>Cr>Ba>Ag>Pt>Pd ions in mixed solution of various metal ions at pH 4.7. Chitosan derivative were synthesized treating with pyridine and pyridine derivatives to give them a high selectivity in adsorption of metal ions. The chitosan derivatives(6, 7) demonstrated their selectivity on precious metals among various metal ions distinctively. that is chitosan derivatives had a peculiar selective adsorption on Pb, Cr and Cu ions in mixed solution of various metal ions at pH 1.0. The chitosan derivatives are characterized by ^1H-NMR and IR spectrum.

본 연구에서는 대학교육의 질 제고를 위하여 지향해야 할 ‘학습자중심교육’의 특성과 원리를 도출하고 이러한 요소들에 대한 교수들의 중요도와 실행도 인식을 분석하였다. 이를 위해 3개 대학의 전임교수들을 대상으로 설문조사와 면담조사를 실시하였다. 학습자중심교육의 특성에 대한 중요도와 실행도 차이 분석결과, 학습 자중심교육의 5가지 영역 27개 항목에서 모두 유의한 차이를 보였으며, 중요도 인 식에 비해(M=4.09, SD=.38) 실행도는 낮게 나타났다(M=3.62, SD=.49). 또한, IPA분 석을 통해 향후 집중적으로 실행 노력을 기울여 개선해야 하는 항목으로 학습관 및 학습목표 영역의 특성들이 도출되었다. 그리고 면담을 통해 대학 교수들이 인식하 는 학습자중심교육에 대한 개념, 필요성, 실행 상의 어려움, 설문 결과에 대한 원인, 학습자중심교육에 기초하여 수업을 개선하기 위한 방안을 규명하고 제시하였다. This study investigated the attributes and principles of learner-centered education, then analyzed the professors perceptions on importance and performance of learner-centered education. For this, the survey and interview with faculties from 3 universities were conducted. As a result, the differences between importance and performance of every items were significant, the scores of performance were lower than those of importance. By IPA result, ‘concentrate here items which should make more efforts to improve were derived in areas of learning philosophy and objectives. Based on the survey results, the concepts, needs, difficulties of implementing to learner-centered education, reasons of survey results, and strategies of improving the teaching were suggested by an interview.

The role of Cl channels in regulatory volume decrease (RVD) in human salivary gland acinar cells was examined using a whole-cell patch clamp technique. Human tissues were obtained from healthy volunteers or from patients with oromaxillofacial tumors. During the measurements, K+-free solutions were employed to eliminate contamination of whole-cell conductance by K+ currents. When the cells were exposed to a 70% hypotonic solution, outward-rectifying currents, which were not observed in the resting state, were found to have significantly increased both in human labial and parotid gland acinar cells. The amplitudes of the currents were reduced in a low Cl bath solution. Furthermore, the addition of 100 μM 5-Nitro-2- (3-phenyl propylamino) benzoic acid (NPPB) or 100 μM 4,4'-diisothio cyanatostilbene -2,2'-disulphonic acid (DIDS), known to partially block Cl channels, significantly inhibited these currents. Its outward-rectifying current profile, shift in reversal potential in a low Cl bath solution and pharmacological properties suggest that this is a Ca 2+-independent, volume activated Cl current. We conclude therefore that volume activated Cl channels play a putative role in RVD in human salivary gland acinar cells.
