Hyperreflexic bladder is a common problem in spinal cord lesion above sacral segment and the management remains a challenge. As a result of markedly elevated bladder pressures these patients often present with urinary incontinence, recurrent urinary tract infection and renal deterioration lastly. We treated the three hyperreflexic bladder patients (2 spinal cord lesions & 1 cerebrovascular accident) with 6% phenol injection through the third sacral foramen for nerve root block. Average of bladder capacity increment was above 300ml and maximal intravesical pressure did not rise above 40cmH2O. Continence was maintained in all cases. Therefore, all patients performed self - catheterization successfully and the volume was 300-500m1. There was no definitive complications. The third sacral nerve root block may be used for hyperreflexic bladder patients who cannot be controlled by anticholinergics.
멀티미디어 데이터베이스에서 SMIL을 이용한 질의어 확장 및 프리젠테이션 시스템의 구현

멀티미디어 데이터베이스 시스템에서 멀티미디어 데이터를 질의하고 결과를 어떻게 프리젠테이션 할 것인가 하는 것은 매우 중요하다. 또한 질의 결과를 다양한 응용에서 사용하기 위해서는 보다 일반화된 형태로 질의결과를 제공해야 한다. 본 논문에서는 W3C의 권고안인 SMIL에서 제공하는 멀티미디어 프리젠테이션의 기능적 요소들을 질의어에서 지원하도록 함으로써 보다 일반화된 형태로 질의어를 확장하고, 또한 다양한 응용에서 사용하도록 하기 위해서 질의 결과를 SMIL 형태로 제공하도록 한다. It is very important how users query MM data and how the query results are presented in MMDB systems. Also, the query results are represented as the generalized form so as to be used in various applications. In this paper, we propose a generalized method for querying and presenting MM data by extending query language based on presentation elements of SMIUSMIL is W3C recommendation for synchronized MM presentation). Our system provides the query results for users as SMIL format in order to be used for various applications.

지금까지 질의 결과에 대한 프리젠테이션은 일반적으로 외부 툴이나 리포트 작성기를 통해 이루어지고 있는데, 프리젠테이션을 작성하는 방법이나 저장 방법 등이 표준화되어 있지 않기 때문에 다른 응용에서 질의 결과를 사용하는 데 많은 어려움이 따른다. 따라서 멀티미디어 데이터를 질의하는 질의어에서 표준화된 방법으로 프리젠테이션을 정의할 수 있는 방법이 필요하다. 본 논문에서는 W3C (World Wide Web Consortium) 의 멀티미디어 프리젠테이션 표준인 SMIL (Synchronized Multimedia Integration Language) 2.0을 기반으로 SQL을 확장하여 멀티미디어 데이터에 대한 사용자가 질의와 질의결과에 대한 프리젠테이션 작성를 원활히 할 수 있도록 한다. The presentation of query results is usually made with an external tool or a report generator but, because the methods of preparing and storing presentations have not been standardized, there are many difficulties for other applications to use query results. Thus, it is necessary for a multimedia data query language to define presentation in a standardized method. In this paper we designed extented SQL is based on SMIL 2.0, which support the proposed presentation model effectively. Furthermore this study proposed methods of using query results in various multimedia applications.

Hydronephrosis due to uroteropelvic junction obstruction is a well recorgnized and common disorder of children and young adults. Its clinical charateristics are vague generalized symptoms, so early detection is not easy. We reviewed fourty five cases of hydronephrosis due to ureteropelvic junction obstruction in the Department of Urology, Chungnam National University, from January, 1981 to December, 1990. The results are as follows; 1. Age distribution of hydronephrosis was 20 cases in old aged group(above 20 years old), 10 cases in 1st decade, 9 cases in 2nd decade and 6 cases in infants. Sex distribution was 28 cases(62.2%) in male and 17 cases(37.8%) in female(male to female ratio was 1.6: 1). 2. Of 45 cases, 39 cases(98.7 %) were unilateral and 6 cases(1.3 %) were bilateral. 'Left kidney was more involved than right. 3. Associated diseases were 13 cases(28.9%), of which congenital anomalies were 6 cases, such as horseshoe kidney(3 cases), ureterocele(1 case), complete duplicated ureter(1 case) and contralateral renal hypoplasia(1 case), and acquired diseases were 7 cases, such as pyonephrosis(3 cases), stone(3 cases) and spontaneous renal rupture(1 case). 4. The operative methods were nephrectomy(23 cases), pyeloplasty(22 cases), isthmectomy(3 cases) and partial nephrectomy(1 case). 5. The pyeloplasty was successful in 19 cases(86.4% ).

We developed a noble assay method for a quantitative measurement of ROS by using anano biosensor system using the highly durable nanocomplex under hydroponics culture conditionsin a greenhouse. The highly durable nanocomplex, in which nano-Ag is bound to silica and PANI, hasbeen synthesized by using γ-irradiation at room temperature. In this study, the sensor electrode has aworking life of at least 3 months and a measuring range of 4~60℃ in the pH 4~8 area. In addition,We developed a manufacture process for mass production of electrode by introducing electronicprinting system (1000 pieces·hour-1). With the ROS sensor, we determined an induction pattern ofoxidative burst in plant when plant pathogen attack the plant. It was suggested a possibility for realtimecontinuous measurement of oxidative burst (ROS) patterns induced by plants.

For the isolation of pure amino acids, it is advantageous to have available chromatographic systems. The method previously outlined in the preliminary form wherein amino acid are eluted from cation exchange resine with citrate solution has proved useful for the seperation of amino acid, but the resolving power has not been sufficient to permit isolation of all the common constitution. In the procedure described in the present study, aspartic acid, glutamic acid, and typosine are isolated by passage of the column of acetate form of Dowex 1×4 using 0.5N acetic acid as eluent and the remaining components of the mixture are seperated through 500W×4 by elution with 1 to 5 N HCI.
