We observed clinical features of 161 patients of acute gastroenteritis who were adimitted to the Department of Pediatrics in the Chosun University Hospital from January 1. 1989 to December 31. 1993. The stool specimen on admission was tested for rotavirus Ag by ELISA(Rotazyme Ⅱ^R)method. The results are as follows : 1) HRV antigen was detected in 97 patients (58.4%) among 161 patients with gastroenteritis. 2) In monthly distribution. 77.7% of cases developed between October and December 3) The majority if patients were under 24month of age with the peak incidnce being between 6-12 month of age. 4) Mean frequency of diarrhea per day were 5.3±2.6 days in HRV antigen rhinorrhea(48.5%), cough(44.7%). Dehydration was noted 87.2% of cases and 93.9% Was isotonic dehydration. 6) The mean duration of hospitalization was 5.3±2.6 days. 7) AST and AIT elevation in HRV group were 91.5%, 42.6% respectively. AST and ALT elevation in Non-HRV group were 73.1%, 26.9% respectively. AST elevation between two group was not correlated statistically. but ALT concentration was significantly increased in HRV group above normal than Non-HRV group (p<0.05%).

A new 3D micromachining method, called Hole Area Modulation(HAM), has been introduced to enhance the current micromachining technology. In this method, information on the depth of machining is converted to the sizes of small holes in the mask. The machining is carried out with a simple 2D movement of the workpiece. This method can be applied for machining various kinds of microcavities in various materials. In this paper, a mathematical model for excimer laser micromachining based on HAM and also determination of optimal laser ablation conditions(width, hole radius, step size, path, etc.) is performed by Genetic Algorithm(GA).

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

Drowning is the second most common cause of accidental death of children in Korea. But the study of near-drowning is very rare in Korea. The purpose of our study is to determine the factors that may influence survival on the basis of submersion time, consciousness state upon admission to hospital, the kinds of water, laboratory findings and neurological outcomes. The survey was performed by a retrospective cohort study on 28 near-drowning victims of less than 15 years of age who were admitted to the emergency room in the Chosun University Hospital between May 1988 & May 1997. The results were as follows :1)Sex distribution was 22 males and 6 females. 2) Submersion time was <5 minutes in 9 cases, 5-9 minutes in 6 cases, 10-14 minutes in 5cases, 15-19 minutes in 3 cases, ≥20 minutes in 5cases. 3) Comatose patients upon arrival were 6/7 cases in the death group(86%) and 2/21 cases in the improved group(10%). They had unfavorable outcomes(P<0.05). 4) The first PH value was mean 7.02±0.12 in the death group and mean 7.31±0.13 in the improved group. There was a statistically significant difference between the death and the improved group(P<0.05) 5) The patients who gad increased blood glucose concentration were all 7 cases in the death group and 12/22 cases in the improved group(54%). The mean blood glucose concentration was mean 424.7235.6㎎/㎗ in the death group and mean 140.182.7㎎/㎗ in the improved group. There was a statistically significant difference between the death and the improved group(P<0.05). 6) The patients who had pulmonary edema upon arrival were all 7 cases in the death group and 1/21 cases in the improved group(46%). They had unfavorable outcomes(P<0.05). 7) The patients who had been submerged more than 15 minutes were all 7 cases in the death group and 6/21 cases in the improved group(5%). They had unfavorable outcomes(P<0.05). We conclude that pediatric victims of near-drowning can be assigned to high or low likelihoods of unfavorable our outcomes with the use of five variables ; comatose mentation upon arrival decreased initial blood pH, increased initial blood glucose concentration, pulmonary edema, and maximum submersion time estimated longer than fiften minutes. This prediction rule may be useful if it can be validated in another cohort.

Liquid phase oxidation of p-xylene using molecular oxygen has been carried out on the Co/Mn/Br-based catalyst system in acetic acid as a solvent. Process parameters(total pressure, partial pressure of oxygen and temperature) and kinetics of the reaction were studied as a basic study in the viewpoint for the development of new catalyst system and process. The total pressure above 20atm and the partial pressure of oxygen above 5atm were required to keep the reactant in the liquid phase and to overcome the mass transfer limitation of oxygen. The oxidation rate conversion were increased with increasing reaction temperature to the 100∼190℃ range. For a given initial concentration of p-xylene, the oxidation rate and the apparent activation energy were found to be of first-order and 4.24 ㎉/㏖, respectively. The effect of the third components added to the Co/Mn/Br catalyst was also studied. It was found that Ni is only a good additive that can promote the catalyst performance.

Recently technological advances have made multimedia on-demand services, such as movies-on-demand and home-shopping, important to the customer market. One of the most challenging aspect of this type of service is to provide on-demand access, that is, users can view the movie either instanteneously or within a small and reasonable latency upon request. One way to reduce the latency is to simply purchase more disk. A more interesting and more economical approach might be to either attempt to improve the data layout and scheduling techniques or to reduce the I/O demand of each request in service through "sharing" of data between requests for the same object. There are several approaches to reducing the I/O demand on the storage server through sharing. Batching and adaptive piggybacking are studing as general I/O bandwidth reduction policies frequently. In this paper, both batching and simple piggybacking performances are analyzed by a simulation, and the performance between batching and simple piggybacking is compared.

Purpose: The aim of this study was to evaluate the short-term outcome of a jejunal interposition, by comparing it with a conventional Roux-en-Y gastrojejunostomy, after a total gastrectomy. Materials and Methods: For 28 patients (20 men and 8 women) with a gastric adenocarcinoma, who underwent an isoperistaltic simple jejunal interposition, weight, hemoglobin, hematocrit, serum protein and albumin, and cholesterol levels were checked before the operation and at 1 year and 2 years after the surgery. Also, endoscopy was performed to confirm reflux esophagitis. In this study, the data were collected between January 1993 and July 1999 at Chungnam National University Hospital, and the results were compared with those of the Roux-en-Y procedure. Results: The body weights at 1 year and 2 years after the surgery had returned to 86.0% and 87.6% of the recent original body weight in the jejunal interposition (Jl) group and to 90.8%, 87.0%, respectively in the Roux-en-Y (RY) group. The levels of hemoglobin (g/dl) were 13.3, 12.5, and 11.9 in the Jl group, and 13.8, 12.6, and 12.1 in the RY group at the time of the operation and at 1 year, and 2 years after the surgery, respectively. The total serum protein (g/dl) levels were 7.1, 7.2, and 7.5 in the Jl group and 7.1, 7.0, and 7.2 in the RY gropu at the time of the operation and at 1 year and 2 years after the surgery, respectively. The serum albumin (g/dl) levels were 4.2, 4.1, and 4.2 in the Jl group and 4.2, 4.2, and 4.2 in the RY group at the time of the operation and at 1 year, and 2 years after the surgery, respectively. The total serum cholesterol (mg/dl) levels were 186.5, 174, and 164 in the Jl group and 213.7, 171.1, and 141.0 in the RY group at the time of the operation and at 1 year and 2 years after the surgery, respectively. The endoscopic finding showed that reflux esophagitis occurred in 7.1% of the patients in the Jl group and in 3.5% in the RY group. Conclusion: We think that from the view point of quality of life, a jejunal interposition, as well as a Roux-en-Y procedure, is a useful reconstruction methods for a total gastrectomy.
