This studies was carried out to investigate the processing possibility of pheasant meat extracts treated with proteases. The crude protein, aminonitrogen, degree of hydrolysis, yield and amino acid composition of pheasant meat extracts when it was treated with proteases at various temperature and reaction time were analyzed. The crude protein contents of pheasant meat extracts processed in 130℃ were more than when it was done in 100℃, but the contents of aminonitrogen were not quite different between two processing temperature. The content of crude protein and aminonitrogen when pheasant meat was hydrolyzed with protease NP and prozyme A. The yields of pheasant meat extracts, when pheasant meat were treated at 100℃ and 130℃, were from 2.24 to 7.10% and from 5.51 to 10.45%, respectively. And the yield of extraction depended on extraction temperature, kinds of enzyme, amount of enzyme, extraction time. The content of aminonitrogen in pheasant meat extracts treated with enzyme was much higher than any other treatments. And it depended on amount of enzyme, extraction time and temperature. The amount of the amino acids in pheasant meat extracts treated by protease NP were eminently higher than by heat at 100℃ or 130℃.

인삼이 밀가루의 아밀로그래프에 의한 호화 성질과 파리노그래프에 의한 반죽 성질에 미치는 영향을 조사하였다. 인삼첨가 LL면의 조직감과 관능적 특성에 미치는 영향을 분석하기 위하여 밀가루에 대하여 인삼을 5.0∼10% 첨가하여 LL면을 제조한 뒤 면의 조직 특성 분석 및 조리시험을 하고 관능검사를 하였다. 인삼을 첨가하면 아밀로그래프의 호화개시 온도를 3.1℃ 지연시켰으며, 최고 점도를 40B.U 감소시켰다. 파리노그래프의 흡수율은 1.2% 증가하였으며, 반죽의 안정도는 인삼의 첨가로 2.0분 길게 측정되었다. Hunter L값은 인삼 첨가량이 증가할수록 낮아졌으며, Hunter a, b값은 반대로 측정되었다. 인삼첨가 LL면의 층밀림 압출력은 첨가량의 증가에 따라 높아져 10.0%의 첨가는 대조구 18.65(㎏f)보다 2.3(㎏f) 높은 23.95(㎏f)로 측정되었으며, 경도도 대조구보다 5.4(㎏f) 높게 측정되었다. 인삼첨가 LL면의 무게 증가는 인삼의 첨가량이 증가할 때 다소 높게 나타났으나. 부피 증가는 오히려 높게 나타나 조직이 다소 치밀한 것으로 나타났다 용출량은 인삼량의 증가에 따라 약간 감소하였다. 미생물은 인삼의 첨가량이 증가할수록 줄어들어서 장기 저장이 가능하였다. 관능 검사 결과는 인삼첨가 LL면이 4.2 및 4.0으로 비교적 좋은 점수를 얻었다. 이같이 LL면 제조시 인삼 첨가량은 7.0%의 수준이 효과가 컸다. The influence of ginseng on the paste or gelatinization properties by amylograph and mixing properties by farinograph of wheat flour, and on quality properties, color, cooking quality, textural and sensory properties, and reducing microbial population of LL (Long Life) noodles was studied. The contents of ginseng used were from 5% to 10% based on flour weight. The viscosity property of wheat flour with ginseng was increased the initial pasting temperature but the amylograph peak viscosity were decreased in vice versa. The farinograph absorption, stability and breakdown were increased by ginseng. The whiteness of LL noodles manufactured with ginseng was lower than that of control. The shear extrusion force and hardness of LL noodles manufactured with ginseng were shown much higher value than those of control. At cooking quality examination of LL noodles manufactured with ginseng, weight of cooked LL noodles was decreased but volume was appeared in vice versa. Extraction amounts of LL noodles manufactured with ginseng during cooking were much smaller than those of control. Total counts of microorganism of LL noodles manufactured with ginseng were decreased during storage at 30℃. Sensory properties of cooked LL noodles which was manufactured with ginseng showed quite acceptable. Based on the cooking and sensory evaluation test, addition of 7.0% ginseng to wheat flour may be suitable for processing LL noodles.

Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.

This paper describes voltage-controlled delta-modulation scheme for active power filters, which is to control the harmonic-compensating current indirectly by adjusting the capacitor voltage to be sinusoidal. The overall control system has two feedback loops : one is the outer proportional feedback for loop regulating the de current of the active filter and the other is the inner feedback loop for maintaining the ac current waveform to be sinusoidal, and to have zero power factor angle(i. e. unity power factor). The characteristics of the proposed scheme are investigated by digital simulation using ACSL.

The fish fauna in the coastal waters of Gageodo Island, South-west Sea, was investigated by SCUBA diving in October 16 and 17, 2002. The fishes observed were classified into 40 species in 23 families. In Autumn, subtropical fishes in such as families as Pomacentridae, Pomacanthidae and Apogonidae, represented 12.5% of the total, while eurythermal species represented 72.5%.

Fluoroneplanocin A (12) was designed as a novel mechanism-based inhibitor of S-adenosylhomocysteine hydrolase (SAH) and efficiently synthesized via an electrophilic vinyl fluorination reaction (n-BuLi, N-fluorobenzenesulfonimide at -78℃). Fluoroneplanocin A exhibited 2-fold more potent SAH Inhibitory activity than the parent neplanocin A. A new mechanism of irreversible Inhibition discovered in this work might provide new alternatives in the design of a different class of antiviral agents operating via SAH inhibition.

Recently, photovoltaic system has been studied widely as a renewable energy system, because it does not produce environmental pollution and it has infinity energy souice from the sun. A study on photovoltaic system has a lot of problems like as reappearance and repetition of some situation in the laboratory experiment for development of MPPT algorithm and islanding detection algorithm, because output characteristics of solar cell are vaned by irradiation and surface temperature of solar cell Therefore, the assistant equipment which emulates the solar cell characteristics Which can be controlled arbitrarily by researcher is require to the ieseaichers for reliable experimental data In this paper, the virtual implement of solar cell (VISC) system is proposed to solve these problems and to achieve reliable experimental result on photovoltaic system. VISC system emulates the solar cell output characteristics, and this system can substitute solar cell in laboratory experiment system To realize the VISC, mathematical model of solar cell is studied for driving converter and the DC/DC converters are compared in viewpoint of tracking error using computer simulation Output dynamic characteristic of PV array is vaned by iriadiation and PWM converter performance is studied using PSIM simulator<br/>
