붕장어 가공부산물인 머리와 frame를 효율적으로 이용하기 위한 일련의 연구로 붕장어 부산물을 이용한 붕장어탕의 개발을 시도하였고, 아울러 이의 식품성분 특성에 대하여도 살펴보았다. 살균조건 및 가온일수에 따른 붕장어탕의 저장성 부여를 위한 최적 살균조건은 F? value=8분으로 판단되었다. 붕장어탕의 일반성분은 수분의 경우 90.7%, 조단백질의 경우 4.8%, 조지방의 경우 2.6%, 조회분의 경우 1.5%를 나타내었다. 붕장어탕의 엑스분 질소 함량은 243.1 ㎎/100 g으로 시판 추어탕의 208.0 ㎎/100 g보다 높았다. 붕장어탕의 총 아미노산 함량은 4,310 ㎎/100 g이었고, 주요 구성아미노산은 glutamic acid(637.3 ㎎/100 g, 14.8%), glycine(409.1 ㎎/100 g, 9.5%) 및 alanine(404.4 ㎎/100 g, 9.3%)등이었다. 붕장어탕은 관능적인 비린내는 거의 감지되지 않았고, 맛은 우수하였으며, 항산화능이 인정되었으나 ACE 저해능은 크게 기대할 수 없었다. For the effective use of the conger eel by-products, such as head and frame, Tang, which is the Korean-type soup, from conger eel by-products (TCEB) was developed and its food component characterization was compared with that of commercial Chueotang, loach Tang. According to the results of viable cells and coliform group of TCEB heated at 115oC for various times, the reasonable F0 value was 8 min. The proximate composition of TCEB was 90.7% for the moisture, 4.8% for the protein, 2.6% for the lipid, and 1.5% for the ash. The extractive-nitrogen content of TCEB was 243.1 ㎎/100 g, which was higher than that of commercial Chueotang, 208.0 ㎎/100 g. The total amino acid content of TCEB was 4,310 ㎎/100 g and its major amino acids were glutamic acid (637.3 ㎎/100 g, 14.8%), glycine (409.1 ㎎/100 g, 9.5%) and alanine (404.4 ㎎/100 g, 9.3%). TCEB was not felt in the sensual fish odor and its sensual taste was good. The health functional properties for health of TCEB were 1.29 as a PF (protection factor) for antioxidative activity and 39.4% for angiotensin Ⅰ converting enzyme (ACE) inhibiting activity.

Background : Studies in animals suggest that pipecuronium dose not induce hemodynamic chan-ges related to histamine release or to an effect on the autonomic nervous system. Therefore the effects of bolus administration of large doses of pipecuronium, up to 0.20 mg/kg, on the intubation condition, onset and duration of neuromuscular blockade, heart rate and blood pressure were studied during fentanyl- nitrous oxide anesthesia. Method : Forty adults were randomly assigned to receive a bolus injection of either 0.05, 0.10, 0.15, 0.20 mg/kg of pipecuronium. Neuromuscular blockade was measured using mechanomyographic activity of the adductor pollicis muscle after supramaximal stimulation of the ulnar nerve. Four subgroups of 10 patients received pipecuronium doses of 0.05, 0.10, 0.15 and 0.20 mg/kg, respectively, as an intubating dose. Results : The times of onset and clinical duration(mean sem) after each dose were as follows: 0.05 mg/kg, 2.98 0.42 and 41.5 2.42 min; 0.10 mg/kg, 1.54 0.06 and 82.9 7.48 min; 0.15 mg/kg, 1.41 0.14 and 124.8 13.1 min; 0.20 mg/kg, 1.12 0.05 and 187.1 12.8 min. The intubation condition, time of onset and duration after doses of 0.05 mg/kg were significantly different from values after the higer doses. The duration was increased with dose-increments. No dose-related changes in heart rate or blood pressure were observed. Conclusion : The authors conclude that dose of 0.10 mg/kg and over has good intubation condition clinically and large bolus dose of pipecuronium can be safely used with a significantly prolonged duration of action without hemodynamic change.

Epidural clonidine is reported to produce analgesia in humans. To investigate the analgesic effect and prolongation of epidural and spinal anesthesia, we mixed 0.2mg epinephrine, 150 mcg clonidine, or 1 cc normal saline with 0.5% bupivacaine and compared the hemodynamie and analgesic effects of each drug. Heart rate and blood pressure were checked before, during and after anesthesia. Sensory level was checked by pin-prick method. The results were as follows; 1) The analgesia onset time and the time to highest level of sensory loss was most rapid in the epinephrine group. 2) The two segment regression time was significantly prolonged in the epinephrine group. 3) The analgesia duration was significantly prolonged in the clonidine and epinephrine group. 4) Although the heart rate gradually decreased over 60 min. After injection of each drug, there was no significant change between the groups. 5) Blood pressure decreased over 20-30 min. After injection of each drug, but there was no significant change between the groups.

Recently increasing amount of efforts has been devoted to the improvement of logistics in the marine products industry. Yet, few studies have been conducted on the development of site selection models of marine products centers. This paper proposes a systematic assessment model for the decision making, which is composed of a set of evaluation criteria and an appropriate evaluation method. In choosing criteria we consider completeness and comprehensiveness to reach a right solution. For more flexibility of the model in the future, this study proposes two sets of criteria according to the size of planned centers. The Analytic Hierarchy Process (AHP) is adopted in this study, since the criteria incorporate both subjective factors and objective factors and the AHP is known effective in the situation. This study then illustrates the model application with plausible alternatives. Finally, a dependency problem in the decision criteria is discussed and the Analytic Network Process (ANP) is recommended, in the context, as a solution method.

Recently expanded and enhanced software system inevitably demands serous managerial considerations on its maintenance cost. This study proposes a systematic and thorough assessment model for software development methods to the end of maintainability, incorporating ISO 9126 quality standards-based criteria. The Analytic Network Process (ANP) is employed in our model to find the effect of any dependency among the items of the criteria and the alternative methods. This study then applies the model empirically in order to evaluate the efficacies of the Structured Method and the Objected-Oriented Method. At first, this study performs the test on the existence and direction of any dependency under the three types of assumptions, and then determines the relative dominance of the two methods.

윤석영,홍민표,김은호,공광훈 중앙대학교 기초과학연구소 2000 基礎科學硏究所 論文集 Vol.14 No.-

Alcohol dehydrogenase from Thermomicrobium roseum was purified to electrophoretic homogeneity approximately 77-fold with a 38% activity yield by adenosine 5'-monophosphate and Mono Q column chromatography. The molecular weight of the enzyme was determined to be approximately 43,000 by SDS-polyacrylamide gel electrophoresis and 88,000 by gel chromatography, indicating a homodimeric structure. The Km and Vmax values of the enzyme for ethanol were 24.2 mM and 12.8 ㎛ol/min/mg, respectively. Pyrazole notably inhibited the enzymatic activity. Ca2+ ion activated the enzyme activity, but Cu2+ inhibited. The activity of the enzyme was optimal at pH 10.0 and 60℃.

It is important to interpret the soil chemical properties in order to effectively manage the farmland. This study was conducted to investigate the soil chemical properties of upland soybean field according to the soil series at 32 upland fields located in the parts of Gangwon-do. Soil sampling sites were selected by using the National Statistics DB and KSIS DB that is a soil environment information system provided by the Rural Development Administration. Soil samples were collected from 0~15 cm of top soil before seeding or transplanting, air-dried, passed through a 2 mm sieve, and analyzed for soil pH, EC, organic matter, available phosphorus (P2O5), exchangeable potassium, exchangeable calcium and exchangeable magnesium. The average chemical properties have exceeded the each nutrient optimum range level of RDA, except the organic matter in experimental soil 2015. And despite application of conventional fertilization, each soil series nutrient contents were change respectively. The results of this study suggest that conventional fertilization should be applied based on the analysis about the amount of accumulated nutrient contents in the soil.
