Purpose : The purpose of this study was to evaluate the effect of nutritional support with enteral liquid supplement in cancer patients receving chemotherapy for possible benefit in nutritional, immunologic and golbal function of patients. Patients and Methods : From October 1995 to February 1997, 30 advanced cancer patients receving chemotherapy were divided two roups. The Nycare group, in addition to normal diet, Nucare^R enteral supplement was given for 1week right after chemotherapy for the duration of 2 chemotherapy cycles. Control group received only normal diet without parenteral fluid supplement for 2 chemotherapy cycles. Results : Median ages were 53 end 56 years for Nucare group and Contrl group respectively. Performance scores was less than 2 by ECOG scale. All patients were stage Ⅲ or Ⅳ. The physical parameters, such as weight, arm muscle circumference(AMC) and triceps skin fold(TSF) were decreased in both groups after 2 cycles of anticancer therapy. but it was less severe in Nucare group(p<0.05). Serum transferrin was maintained in mild deficit state in Nucare group, whereas it aggravated form mild to moderate deficit in Control group(p<0.05). Serum albumin level increased in Nucare group without statistical significance. but it decreased from normal to mild deficit in Control group. Serum total protein did not change significantly in Nucare group. but in Control group, serum total protein was decreased from 7.24±0.9 to 6.52±0.5(P<0.05). Total lymphocyte count did not change significantly in both groups. Conclusion : This study shows that the nutritional support with Nucare^R was effective in the prevention of nutritional deficit status in patients receving a nticancer chemotherapy.

The immune response is dependent on phagocyte function. When this function is deficient or enhanced, the patient is susceptable to a large variety of disease. Enhanced function results in an over active immune response. This study was carried out to investigate whether water extracts of Sijunzi-Tang and Radix Glycyrrhizae have inhibitory effect of neutrophil superoxide generation and cell injury. Superoxide was generated by rabbit polymorphonuclear leukocytes (neutrophils) stimulated by tert-butylhydroperoxide(t-BHP), and was measured by luminol and its detector chemiluminometer. The inhibitory effect of extracts against t-BHP induced superoxide generation was dose-dependent in the range of 0.1~1% concentrations. Cell injury was estimated by measuring lactate dehydrogenase(LDH), and lipid peroxidation was examined by measuring malondialdehyde(MDA), a product of lipid peroxidation. When rat renal cortical slices were treated I mM t-BHP, water decocted herbs inhibited LDH release from the slices as partially dose depecdent manner. It shows that herbs can reduce cytotoxicity, but over dose can be toxic to the slices. And MDA measurement shows the effect of Sijunzi-Tang and Radix Glycyrrhizae inhibiting cytotoxicity from oxidants, partially depend on preventing lipid peroxidation of cells. HPLC data shows the antioxidative effect of Sijunzi-Tang depends on the effect of Radix Glycyrrhizae. So further studies should be followed to make clear the mechanisms of antioxidative effects.

The purpose of this study was to educe presumed formula that guess the relation between ??max by indirect method and by the event for simple examination of physical fitness with 40 adults. The results of this study were as followings : 1. On a average, ??max was 3.16ℓ/min within the scope of 2.6∼4.6, 45.38㎖/㎏, and 52,00㎖/LBM/㎏. 2. It was found that ??max and BT2 (Burpees test 2min) were correlative highly and significant within P<.001. 3. As the result of recurrent analysis of ??max, item of basic test, and 5 events for the simple test of physical fitness, it was found that BT2, lung capacity, and rest heart rate in keeping equilibrium are significant independent variable that preestimates in 65%(r=.64). 4. The recurrent formula that can presume ??max is as following. y=7.8563-0.032729(BT2)+0.18335(VC)-0.012835(rest HR)

Above 130 accessions of pepper consisting of 50 introductions from Mexico and Nepal, and resistant and susceptible controls were tested for resistance to bacterial wilt and to Phytophthora root rot at seedling stage by artificial inoculation. As the results, KC897, KC939, KC936 were newly found resistant to bacterial wilt in addition to already known resistance sources such as KC126, KC350, KC351, KC353. No new sources of resistance to Phytophthora root rot were found among the introductions from Mexico and Nepal.

To analyze the effects of provision of school lunch (PSL)on the development of children physical physique, 666(boys 343, girls 323)students of K. elementary school (PLS) were compared with 981(boys 491, girls 490)students of C. and K. elementory schools (none PSL) concerning about standing height, sitting height, body weight, chest circumference, and Rohrer index. The conclusions from the results were as follows : 1) There was no significant differency on standing height between PSL and non PSL groups. 2) It shows significantly high on sitting height in the none PSL group of girls of 10 years old. 3) On the body weight and Rohrer index the boys group in PSL 11 years old were presented significantly high, but there were no difference in the other's age group. 4) In the group of 10 years old boys and of 10,11 and 12 yeas old girls were showed significantly higher status on chest circumference in none PSL groups.

This study investigated the phenomena of membrane fouling by NOM and the effect of the fouling on removal of micro-pollutants. NOM has a great effect on decline of permeate flux. Permeate flow rate was reduced by 88% in RO and 34.8% in NF for 323hr operation period. Removal rate of UV_(254), is 87.4% in RO and 78.5% in NF and removal rate of DOC is 42.7% in RO and 32.9% in NF for 2㎎/l humic acid. Removal efficiency of the micmpollutants by the RO and NF membranes fouled by humic acid was mostly lower than that by the new membrane. The concentration polarization which affects the flux and the rejection was thought to occur in the active layer of the membrane, as the membrane was getting fouled.

Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.
Efficient Glitch-Generation Estimation in Logic Systems
Kim,Min Su,Noh,Yong Whan,Choi,Jung Yun,Kim,Young Hwan 대한전자공학회 1997 ICVC : International Conference on VLSI and CAD Vol.5 No.1
In this paper, we present an efficient probabilistic method that estimates the generation of glitches in logic systems. The analysis results can be used to locate the logic blocks to modify for power reduction by decreasing the chance of glitch generation. To propagate signal transitions in a circuit, the proposed method uses a notion of delay sets that carry the information on the time points of signal transitions along with transition probabilities. The method considers the typical spatial correlation of signals, and decomposes the logic gates with the large fan-in into smaller gates before analysis to improve efficiency for practical use at the small sacrifice of analysis accuracy.
