Recent efforts on syntax-directed programming systems have shown the incremental parsing technique is basic and essential part of the system. We extended a conventional LR Parsing table to accept nonterminal symbols as well as terminal symbols, and also to accept incomplete sentences as input string. We use a parse tree to store the parse sequence and to retrieve previous parse sequence. With the extended parsing table and incremental parser driver, we can generate an efficient incremental parser automatically.

Heine's Retinoscope is 100% dust proof and incorporates a unique Integrated Polarizing filter which eliminates all internal glare, providing for a clearer, brighter papillary reflex, enhancing performance and ease of examination, As a result of their data basis, we observed and analyzed which instrument has lesser occurring refracting aberration. Contact lens Wearers assuming best visual acuity lead 1.0(20/20) performed over refraction using Retinoscope. Auto Refractor, Auto Refrac-Keratometer and Suresight. The Auto refractor provides highly accurate measurement of patients refraction error. Auto Refrac-Keratometer provides precise and efficient refraction and Keratometry measurements and suggests contact lens base curve values. The automatic calculation of residual astigmatism assists in fitting RGP lenses. Also, suresight is a most convenient instrument for refraction. 30 contact lens wearers are chosen regardless of age, sex, and job. At least 30 minute after placing contact lens in each subjects eye, Performing over refraction by use of Retinoscope, Auto refractor, Auto refrac-Keratometer and suresight. Then presenting each results by graph in consist of spherical part, cylinder, axis, left eye and right eye separately.

Microarrays can provide detailed information of the expression patterns of thousands of genes in tumours, but due to systematic variations such as dyes, hybridization and processing precedures, and technical attefacts, true biological differences in gene expression levels cannot easily be detected. If the vast quantity of these microarray data can be suitably normalized, the impact of this genomic expression data on the understanding of diagnosis and treatment of disease will be profound. Statistical normalization approaches to microarray data are not as yet fully explored and need to be continuously evaluated. We compared the currently much used normalization methods and recently proposed statiostical normalization methods of ANOVA with oligonucleotide microarray data of hepatic nocular lesions indluding hepatocellular carcinoma. This article proposes combined normalization methods of ANOVA after a robust local lowess, intensity and print- tip dependent, regression.

Lovastatin(LV), one of the potent cholesterol-lowering agents, is an inactive lactone prodrug which is metabolized to its active open acid (Lovastatin acid. LVA). In order to optimize the assay procedure of LVA by high performance liquid chromatography(HPLC). solid phase extraction(SPE) method and protein precipitation method were employed for the pretreatment of plasma sample containing LV and LVA, and plasma sample was hydrolyzed under alkaline condition to transform all LV to LVA. Following pretreatment of plasma sample. 100ul of sample was injected onto a reversed-phase C_18 column and eluted with a acetonitrile-pH 3.0 phosphate buffer mixture(45:55 v/v) at a flow rate of 2.0ml/min. Ultraviolet detection was carried out at 238nm. It has been shown that all of LV in plasma was converted to LVA in vitro under alkaline condition. On SPE method, elution with acetonitrile-methanol mixture(75:25 v/v) indicated the highest recovery of LVA, but acid treatment of plasma sample before loading on SPE cartridge revealed little effect on recovery of LVA. Compared with two different pretreatment of plasma sample, SPE indicated better sensitivity and recovery.

Objectives : To understand the motor recovery pattern after spinal cord injury, We designed the quantitative measuring method of locomotion recovery using computerized motion analysis combined with video recordings. Materials and Methods : Using computerized motion analysis technique, locomotions of the 10 cord-hemisected Sprague-Dawley rats on the treadmill were graphically analyzed. Patterns of foot trajectories were plotted on two dimensions before and after unilateral spinal cord hemisecion at T7 level. Result : Immediately following dorsal hemisection, patterns of foot trajectories altered dramatically. Walking speed, stride length and height of hindfoot movements were markedly reduced. Coordination of left and right hindlimb was also disrupted. Although the lesions were unilateral, locomotor behavior was distrubed bilaterally. However, by six weeks, stride length and coordination of hindlimbs returned to near normal but vertical movement of the hindlimb recovered very little. Forelimb-hindlimb coordination was also initially disrupted but partially returned within three weeks. Conclusion : Computerized motion analysis is a sensitive technique for the detection of minor motor deficits following nerve injuries.

In a series of 20 young rats, three cortical lesions were made in each hemisphere. Two of these lesions were filled with avitene and gelfoam, while the third was left empty as a control. The animals were killed successively on weeks 1, 2, 4 and 8 after the operation. The results were as follows : 1) Although there was no difference in the type of tissue reactions, avitene was more rapid and profound than gelfoam in the process and degree of inflammatory reaction at the same periods. 2) Avitene biodegradaded more rapidly than gelfoam. 3) The extent of fibrosis and adhesion to the surrounding brain tissues were not grossly different between these two agents but more profound histopathologically in avitene at the same periods. With these results, we could conclude that the avitene was superior to the gelfoam as the hemostatic agent in neurosurgical area.

Henoch-Schonlein 자반증은 피부, 위장관, 관절, 신장 등을 주로 침범하며 소혈관염을 기본 병리 소견으로하는 전신성 혈관 장애 질환이다. 위장관계 증상으로는 복통, 오심 및 구토, 잠혈, 토혈, 흑색변 등이 있을 수 있고, 이러한 증상은 합병증 없이 회복되는 것이 보통이나 드물게는 장중첩증, 장벽경색 및 괴사, 장천공 등의 심한 합병증을 동반할 수도 있다. 이러한 위장관계 증상들은 특징적인 피부 소견에 선행하여 나타날 수도 있으며, 이때는 급성복증에 대한 감별진단이 중요하다. 저자들은 장벽경색이 선행하여 감별진단에 어려움을 겪고 시험적개복술을 시행한 이후에 특징적인 피부 자반이 발현되어 Henoch-Schonlein 자반증으로 진단할 수 있었던 증례를 경험하였기에 이를 보고하고자 한다. 본 증례는 입원 1일전부터 시작된 복통을 주소로 입원한 5세 남아가 배꼽 주위에 심한 경련성 복통을 지속적으로 호소하였고 이학적 소견상 배꼽주위의 압통, 장음의 감소, 흑색변 등이 있었으며 소장조영술상 공장 부위에 미만성의 불규칙한 점막비후 소견을 보여 제 8병일에 시험적개복술을 시행한 결과 근위 공장에 국한된 장괴사의 소견이 발견되어 절제 및 문합술을 실시 하였다. 병리학적 검사에서는 장벽경색의 소견을 보였다. 수술후에 복통은 완화되었으나 경미하게 지속되었고, 제 13병일경에 급성 부고환염이 병발되었다가 회복되었고 제 15병일경에는 하지에서부터 발현된 자반이 3일간 지속되었다. 결구 Henoch-Schonlein 자반증과 이의 합병증으로 발생한 근위 공장의 장벽경색으로 진단하였다. Colicky abdominal pain as symptom of Henoch-Schonlein purpura occurs in up to 70% of patients, and results from submucosal edema and hemorrhage. Abdominal pain and other GI symptoms such as nausea, vomiting, melena and hematemesis resolve mostly without any complications. But rarely life-threatening GI complications such as intussusception, intestinal mural infarction and necrosis, and massive hemorrhage may develope. In 14% of patients, abdominal pain may precede other symptoms, and creats diagnostic difficulties. We reports a case of the Henoch-Schonlein purpura presented with colicky abdominal pain which resulted from intestinal mural infarction and preceded characteristic purpuric skin lesion by several weeks. This 5 year old male patient complained of colicky abdominal pain, nausea and melena. Exploratory laparatomy was done and revealed intestinal mural infarction in proximal jejunum. One week later operation, purpuric skin lesion develiped in both leg and feet, and then, Henoch-Schonlein purpura was diagnosed.
