Plate heat exchanger consists of thin, rectangular, pressed sheet metal plates that are sandwiched between full peripheral gaskets and clamped together in a frame. The frame has a fixed end-cover plate, fitted with the connecting ports, which is bolted together with a movable cover plate to hold the embossed plates in between; the top and bottom carrying bars allow proper alignment of the plate stacks. When compared with the well-established shell and tube heat exchangers, the plate heat exchanger shows a lot of advantages like high NTU values, compactness, low cost, multi duties and reduced fouling etc. Plate heat exchangers are often used to transfer heating or cooling water which is produced in the energy production( district heating or district cooling) facilities to residential areas and industrial parks. The district cooling systems of Middle East are the biggest market of plate heat exchanger, but the technical specifications for cooling system are different from the domestic one. To achieve its specifications, the new plate heat exchanger was developed, and its thermal performance results are introduced in this paper.

We have reviewed 11 cases of Disseminated Intravascular Coagulation (DIC) admitted to the Pediatric department of Kyungpook National University Hospital from January 1981 to July 1982. Age distribution showed 4 cases below, year of age including 2 neonatal cases, 2 between 1 to 5 years of age, 2 between 6 to 10 years of age and 3 between 11 to 15 years of age. Three of these 11 cases are male and the rest 8 female. DIC developed within the first 5 admission day in 7 cases, from the 6th to the 10th day in one and after the 10th in three. Factors predisposing to DIC included infection (11 cases) which were usually systemic, shock, recent surgery and malignancy. Diagnostic coagulation studies included low platelet count below 100,000/cumm (all 11 cases), prolonged PT (10 cases) and PTT (all 11 cases). All patients had abnormal hemorrhage and the majority being petechiae on the skin (8 cases) followed by oozing from the injection site (6 cases), melena (4 cases), epistaxis (3 cases), bleeding from the oral cavity (3 cases), intracranial hemorrhage (1 case) and hematuria (1 case). Local ischemic manifestations probablly due to the thrombus formation were respiratory distress (9 cases), mental disturbance (9 cases), diarrhea (8 cases), abdominal pain (7 cases) and acrocyanosis (3 cases). Shock due to systemic circulatory disturbance was also seen in 5 cases. Treatment included transfusion of fresh whole blood and Vitamin K admimistration in all cases, plalelet transfusion in 6 cases, Corticosteroid administration in 4 cases and none received Heparin. Only 3 cases showed improvement and the rest discharged hopelessly and/or died. key words: Disseminated Intravascular Coagulation.

To investigate the effect of Shudihuang(熟地黃) aqua-acupuncture at the meridian points BL 23 on the renal function in normal and two kidney one clip Goldblatt hypertensive rats. The results of this study were as follows : 1. Urine volume, free water clearance rate were significant increased after Shudihuang aqua-acupuncture in normal rats. 2. Urinary excretion on potassium and chloride, glomerular filtration rate were significant decreased after Shudihuang aqua-acupuncture in normal rats. 3. Urine volume, ruinary excretion of electrolytes were significant decreased after Shudihuang aqua-acupuncture in two kindney one clip Goldblatt hypertensive rats. 4. Free water clearance, glomerular filtration rate were significant increased after Shudihuang aqua-acupuncture in two kidney one clip Goldblatt hypertensive rats.

In this study, additions of aluminium foil eching characteristics were compared with sulfuric acid for capacitor. sulfuric acid and ethylene glycol is used as addition, characteristics of funtional group from addition were guessed by comparing of aluminium foil eching characteristics. When sulfuric acid was added in HCI etching solution, corrosion of aluminum metal was inhibited by the chemical adsorption of sulfate ion, when ethylen glycol was added in HCI etching solution, corrosion inhibited by the chemical adsorption of OH^ion.

Background: Urinalysis is a useful laboratory test in the diagnosis of various diseases. In sampling for the urinalysis, there is much concern about contamination that can lead to misdiagnosis in the mid-stream urine sampling method. We conducted this study to determine, in terms of concordance of results and contamination in culture, whether there was any superiority in nod-stream sampling methods with or without disinfection measures compared to the catheterization method. Materials and Methods: We used three kinds of urine sampling methods sequentially, mid-stream non-clean catch, mid-stream clean catch, and catheterization, for ambulatory, non-pregnant, non-men-struating female patients who visited NHIC Ilsan Hospital emergency department during a one-week period in September 2001. Each sample was electrophotometrically analyzed for leukocyte esterase, nitrite, and blood by using a reagent strip and was cultured immediately or after overnight refrigeration. Results: Of the 41 patients, 9 had culture-proven urinary tract infections. The concordance rates(kappa) for nitrite, blood, and leukocyte esterase were 0.875, 0.403, and 0.406 between non-clean catch and catheterized samples and 0.875, 0.481, and 0.560 between clean catch and catheterized samples, respectively. The contamination rate of the non-clean catch, the clean catch, and the catheterized samples were statistically different: 51.2%, 29.3% and 0%, respectively. Conclusion: We found that cleaning with disinfectant was effective for reducing the contamination rate, even though the best urine sampling method for zero contamination was catheterization. We recommend considering cost, patients' comfort, an acceptable threshold for contamination, and the necessity for a culture before choosing a urine sampling method for women who visit the emergency department.

For the proposal of Microcystis aeruginosa control technique by coagulants, removal effects of coagulants were carried out using isolated strain and collected water bloom of M. aeruginosa on Downstream of the Nakdong River. Both of purified and field-collected M. aeruginosa were entirely sedimented by the addition of the coagulant Ceramic-Zeolite type Co 100 (1.5 mg/l) within 24 hr, but Yellow loess (10 mg/l) was less effective for the removal of M. aeruginosa within 24hr. Thus it was concluded that Ceramic-Zeolite type Co 100 was the most effective coagulant.

Clinical effects of rhG-CSF were investigated in 17 patients receiving chemotherapy for non-Hodgkin's lymphoma. Patients were given G-CSF 2㎍/㎏/day after 2nd cycle chemotherapy for least 14 consecutive days, and clinical and laboratory results were compared to results of the first cycle. Treatment with G-CSF resulted in increase of mean WBC count(952.9±152.2㎜³vs 1882.4±350.4/㎜³) and neutrophil count(212.9±53.0/㎜³vs 841.5±238.0/㎜³), reduced the duration of leukocytopenic days(12.4±1.3 days vs 5.5±1.0 days, WBC count less than 4000/㎜³) and neutropenic days(4.5±0.9 days vs 2.3±0.7 days, neutrophil count less than 500/㎜³), and reduced the duration of neutropenic fever(5.8±1.1 days vs 0.9±0.5 days). The side effects of G-CSF were not so significant. These results demonstrated that G-CSF is safe and useful for the treatment of neutropenia induced by anticancer chemotherapy of non-Hodgkin's lymphoma and reducing the incidence of febrile periods and duration of antibiotic administration.
