A biological assessment of water quality was carried out in stream of the near Andong lake from June 2002 through March 2003. The benthic macroinvertebrates collected seasonally from 5 field sites were indentified mostly up to species level. The benthic macroinvertebrates collected from the surveyed sites were composed of 77 species, 62 genera, 44 families, 13 orders, 5 class, 4 phyla. Among these phyla, aquatic insects in Arthropoda were 69 species, 37 families, 8 orders. Dominant species occurring in all the field sites were mostly Chironomidae sp. 1, Baetiella fuscatus and Rhopalopsole mahunkai. The dominance indices(DI) showed the highest as 0.929 at site 3 and the lowest as 0.758 at site 5. The species diversity indices(H´) showed the highest as 1.964 at site 5 and the lowest as 1.128 at site 3. Ecological score of benthic macroinvertebrate(ESB) showed the highest as 33.3 at site 5 and the lowest as 17.8 at site 1. It was α-mesosaprobic in site 1 and site 3 the others was β-mesosaprobic that the water quality estimated by ecological score of benthic macroinvertebrate community.

The ice cream, a type of freezing food of condensed state of milk, richer in nutritions and easily available in all seasons, is one of luxuary items. The fatty acids in the milk is the most important component of ice cream which not only improve the nutritional value but also is easier digestive, more rapidly absorbed than those of plant and also has influence up the quality of the goods. In order to see the fatty acid distribution of the fats in the ice cream on the market, the ice creams on the market were selected in accordance with things most in demands of each manufacture divided into the shape. and analyzed for the concentration of total lipid, acid value, iodine value and saponification value. For the compositional analysis of fatty acid of milk as basis and those gas liquid chromatography was also used. The following were the results obtained. 1) The average total lipids in milk and, the 3 kind of ice creams shaped carton, cone and bar were 3.04, 8.34, 6.41, and 5.4% respectively. 2) The average acid values of milk and each of 3-different type of ice creams shaped carton, cone and bar were 0.72, 0.62, 0.76, and 0.95 respectively. 3) The soponification values. Ranged from 180 to 260, varied great degree depending upon. the different manufactures, the average saponification value of the milk and each type of ice cream shaped carton, cone and bar were 208, 226, 226 and 215 respectively. 4) The iodine values varying great degree upon the different manufactures ranged from 10 to 32, the average values of milk and each type of ice cream shaped carton, cone and bar were 29, 20, 19 and 22 respectively. 5) The fatty acids analyzed for milk and ice cream, were 17-different kind, for the milk palmitic acid appeared principal constituents which valued 29.8%, whereas oleic acid were 27.1%. Since the compositions of fatty acid in ice creams for each different manufacture varied so great degree from manufacture to manufacture that the average values of those for the same shaped ice creams seems to have no meaning, if the compositions of fatty acid in the ice cream were considered according to the manufactures such as A, B, C, D and E companies. 27.4% lauric acid which was principal constituents, 17.8% palmitic acid and 11.8% oleic acid which was equal to 1/2 of that in the milk were found in the product of A company, 28.2% oleic acid and 27.8% palmitic acid which had similar pattern with the composition as that of milk in the product of B company, 25.5% palmitic acid, 22.7% oleic acid and 11.6% lauric acid in the product of C company, 34.4% lauric acid, 15.6% palmitic acid and 8.6% oleic acid which amounts to 1/3 of that in the milk in the product of D company, and 24.6% lauric acid and 18% palmitatic acid in the product of E company respectively. For the ratio of saturated to unsaturated fatty acid, these were 84 : 16 in the product of At 62 : 38 in the product of B, 68 : 32 in the product of C, 88 : 12 in the product of D, 79 : 21 in the product of E respectively, while this ratio for milk was 63 : 37. Although the compositional characteristic of fatty acids in the ice creams varied great degree according to the manufactures, all kinds of different shaped product showed the same pattern in composition regardless of the type of ice cream shaped in provided they were made in the same company. The lauric acid was more exuberant, however oleic acid, unsaturated fatty acid, was of less quantity than in the milk fat. In general, there was less quantity of unsaturated fatty acid in the ice creams compared with in milk.

The Effect of Spaced Repetitions on Korean Elementary Students` L2 English Vocabulary Learning

In this article, the effect of spaced review on Korean elementary students` English vocabulary learning is investigated in an attempt to find an optimal way of teaching and presenting new words in the context of textbook-based instruction. Sixty fourth graders participated in Experiment 1. They learned new vocabulary through four classroom activities on three different spaced schedules: four 10-minute presentations with one activity each, two 20-minute presentations with two activities each, and one massed 40-minute presentation with all four activities. It was found that there was no significant interaction between review spacing and vocabulary gain. Experiment 2 replicated the procedure of Experiment 1 with new words and participants (n = 57), the results of which reaffirmed the earlier finding. This indicates that spaced learning may not bring about a strong facilitative effect on beginner-level foreign language learners` vocabulary acquisition and that there exist many other variables modulating the effect to a larger extent than the sheer frequency of repetition.

It has been known that arteriovenous malformations, involving gastrointestinal tract is often found to be the bleeding, in patient who present chronic anemia with or without specific past history and family history. Clint, et al. Report.d 47 arteriovenous malformations of gastrointestinal tract. In 22 patient (45%) arteriovenous malformations were found at terminal ileum, cecum, ascending colon and hepatic flexure, and rarely it was found at jejunum, ileum, stomach and duodenum. We have found each cases of arteriovenous malformation arising from stomach and jejunum. Diagnosis was confirmed by biopsy in each cases. A case of stomach arteriovenous malformation, the patient was a 67 year old male who complained of epigastric pain, hematemesis, melena and shock. The UGI series revealed a filling defect in greater curvature of stomach and gastrofiberoscope showed pulsatile mass suspicious of arteriovenous malformation. Diagnosis was confirmed by surgery and biopsy. A case of jejunum arteriovenous malformation, the patient was a 50 year old female who com- plained of painless melena and chronic fatigue. The patient appeared anemic on physical examina- tion. Gastrofiberoscope and colonofiberoscope were negative. However angiogram showed evidence of arteriovenous malformation at branch of jejunal artery. Diagnosis was also confirmed by surgery and biopsy.

Dieulafoy ulcer is a distinctive arteriovenous malformation of gastric fundus, which presents with massive or recurrent gastrointestinal bleeding. The lesion is very small and easily overlooked even at laparotomy, and can only be correctly diagnosed by endoscopy or arteriography if the patient is actively bleeding. A 61-year-old man was admitted as emergency to this hospital because of repetitive hematemesis and melena. A history of gastric or hepatic disease was absent. There was no relevant family history, excessive alcohol or NSAIDS including aspirin administraion but a pack of cigaret per day. No telangiectasia or other abnormalities was found on physical examination, but he had obvious anemia and melena. He was found to have hemoglobin 7.1 lg/dl, hematocrit 22%, and a normal platelet count. Two pints of blood were transfused. Emergency gastrofiberscopy was performed during the active phase. A small spurtion blood vessel close to the esophago-gastric junction surround by gastric ulcer on the lesser curvature side of the stomach was identified. Sclerotherapy was done successfully by the multiple local injections of 95% ethanol. After this management, follow up gastrofiberscopy revealed much improvement of the lesion. The long term follow up of his course could not be done.

Marked eosinophilia is found in many kinds of disease state, It usually occur in allergic and parasitic conditions and occ assionally in autoimmune disease, blood dyscrasias, or certain malignancics. Idio- pathic hypereosinophilic syndrome is characterized by markedly elevated peripheral blood eosinophil count without explainable etiology. Eosinophilopoiesis is related with T-lymphocyte activation and cytokine cascade controlling eosinophilic production. It shows tissue infiltration in many organs including endomyocardium, lung, liver, gastrointestinal tract. We have recently experienced a case with idiopathic hypereosinophilic syndrome of a 65-year-old woman who had of complained anorexia, weight loss and diarrhea during the past month and half. Persistantly increased eosinophil count was shown in her peripheral blood, the count averaging 3480/mm'(41% in differential count). Abdominal computer tomography disclosed multiple small relatively ill-defined hypoechoic lesions in the liver. Microscopically, the needle biopsy of the liver revealed heavy infiltration by eosinophilis especially in the portal tracts. On reviewing, previously perfomed endoscopic biopsies from the stomach and terminal ileum also had mild to moderate eosinophilic infiltration, respectively. No evidence of parasitic infection was present on the clinical history and laboratory test. Corticosteroid was administered ard brought marked improvement of clinical manifestations including both hematologic and radiologic abnormalities. (Korean J Gastroenterol 1997; 30:397- 403)

Gastric adenoma is a benign polypoid growth called borderline epithelial lesion, atypical epithelial lesion or flat adenoma. Some authors suggest that it may be a precancerous lesion and its frequent association with gastric carcinoma raises a possibility of its malignant potentiality although unclarified. In this context, we assessed 15 cases with gastric adenoma who visited Koryo General Hospital from 1981 to 1986 and obtained following results. 1) The most patients were in the seventh decade followed by the sixth decade, mean age being 61. 9. The ratio of male to female was 1:1.1. 2) The common clinical symptoms with which patients presented were indigestion (80.0%), epigastric pain and loss of appetite. Epigastric tenderness was observed in 40% of patients on physical examination. 3) UGI series taken in 9 patients showed findings compatible with malignant tumor in 3 cases, peptic ulcer in 3 cases and normal finding in 3 cases. 4) Gastroscopic findings of adenomas were pedunculated polypoid mass in 4 cases, elevated lesion in 2 cases, and multiple small nodules in 1 case. In remaining 8 cases, only nonspecific findings such as superficial ulcers or chronic inflammation were observed. 5) In most cases (13 of 15 cases), gastric adenoma was located in the pyloric antrum as a single in numher. 6) Histologically, only one case was associated adenocarcinoma and two cases showed cellular atypism suspected of malignant change although there was no evidence of malignant cell. 7) 12 cases showed symptomatic improvement with medical treatment and 3 cases who were suspected or confirmed as malignancy by endoscopic biopsy took surgery,

N/A Cancer of the biliary tract usually carries a poor prognosis because the disease involves vital structure early in its course and often become clinically manifest too late for curative surgical theraphy. In these days, it has been suggest that not all cancer of the biliary tree is hopelessly fatal if detect early. In this context, we assesed 39 cases with the malignant tumor of the biliary tree seen at Koryo General Hospital from 1976 to 1985 and obtained following results. 1) The most patients were in seventh decade followed by sixth decade, mean age being 58. 6. The ratio of male to female was 1.3: 1. 2) Sixteenth(41.0%) of the 39 patients of cancer of the biliary tract had the primary tumor in the gall bladder, thirteen(33.4%) in common bile duct, and five(12. 8%) in hepatic duct and ampulla of Vater, respectively. 3) The predominant symptoms or signs with which patients presented were upper abdominal pain(66.7%), jaundice and pruritus. On physical examinations, jaundice was observed in 74.% Of patients, hepatomegaly in 59% and upper abdoninal tenderness in 33.4% 4) The white cell count was found to be within normal limits in 33.3% of patients, showing leukocytosis in 28.2%. Anemia was only observed in 2% of patients. 5) Bilirubinuria was observed in 51.3% and urobilirubinuria in 28.2% of patients. 6) Serum GOT and/or GPT were abnormal in 87.2% and 79.5% of patients, respectively. In 51.3% Of patients serum total bilirubin was above 3.0mg/dl. Serum alkaline phosphatase was elevated in most patients(92.3%) 7) The accuracy, according to the various diagnostic procedures for twenty two patients as follows: In 17 of 19 cass by ultrasonic studies were proved as carcinoma, in 8 of 10 cases by PTC, in 8 of g cases by abdominal CT scan, all of cases by ERCP and in 2 of 7 cases by iv cholangiopgram or oral cholecystogram, respectively. 8) Twenty two of total cases confirmed histologically by operation and/or endoscopic biopsy were as adenocarcinoma but the rest as undifferentiated carcinoma and adenosquamous cell carcinoma, respectively.

N/A Circulating immune complexes are frequently found in the blood of patients with acute or chronic hepatitis type B. Recently, Palla and coworkers reported the apparent presence of HBsAg/IgMspecific anti-HBs complexes in acute and chronic hepatitis B and indicated that the presence of these immune complexes may function as prognostic indicators of chronic evolution. Therefore, we observed for the detection of HBsAg/IgM complexes and studied the significance of their presence in acute and chronic type B hepatitis. A total of 155 HBsAg-positive patients were carried out for this study from Mar, 1980 to Feb. 1986 in this hospital. They were included as 28 patients with asymptomatic hepatitis B carriers, 77 patients with acute hepatitis B, and 50 patients with chronic hepatitis B, respectively. The following results in this study were obtained: 1) Circulating HBsAg/IgM complexes were found in 15 out of 28 (54%) asymptomatic hepatitis B carriers, in 26 out of 77 (34%) acute hepatitis B patients, and in 26 out of 50 (52%) chronic hepatitis B patients, respectively. 2) Circulating HBsAg/IgM Complexes in patients with acute B hepatitis were either absent from the initial hospital day or disappeared from four weeks hospitalization, and recovered clinically within two months. 3) The acute hepatitis B patients, being detectable circulating HBsAg/IgM complexes, had persistent elevation of serum alanine transaminase at least six months period. It is suggested that circulating HBsAg/IgM complexes seem to be of important prognostic and diagnostic value in acute and chronic hepatitis B.
