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.

The present study was designed to examine the effects of aerobic exercise on the change of alpha wave component in electroencephalogram (EEG) and plasma β-endorphin. Exercise consisted of 30-min cycling on an ergometer with the load adjusted to elicit a heart rate rise of 50% between resting and predicted maximal value. The EEG signals and blood samples were obtained before and after 30-min exercise. The EEG signal was digitized at a sampling frequency of 64㎐ and analyzed by means of computer-aided decomposition algorithm and frequency power spectral analyses, respectively. The blood samples were immediately centrifuged for 15-min for quantitative analysis of β-endorphin by means of radioimmunoassay method. Results indicated that β-endorphin was significatly (p<.05) greater after exercise as compared to that of the resting contorol. It was also found that the larger the changes in β-endorphin following exercise, the higher the appearance rate of alpha wave in EEG. There was a positive and signifcant correlation (r=.563, p<0.05) between that increase in alpha wave component and that of the plasma β-endorphin. There results suggest that traquilizer effects of aerobic exercise could be explained, at least in part, by the increase of alpha wave component and plasma β-endorphin which in turn bring about the relaxation effects upon the central nervous system.

Neurofibromatosis type 2(NF-2) is a dominantly inherited disorder characterized by the occurrence of bilateral acoustic neurinomas and the frequent association of other central nervous system tumors. We present a retrospective review of 16 patients with NF-2 who were treated at our hospital from 1984 to 1995 in 13 cases, the diagnoses of Nf-2 were based on the criteria developed at the Consensus Development Conference of National Institute of Health in the United States, and in another 3 cases. the criterias of NF-2 were not fully satisfied, but the diagnoses of NF-2 were highly suspected. The average age of the patients was 27.6 years, ranging from 13 years to 56 years. The most common symptom was hearing difficulty : intervals between symptom onset and deafness ranged from 8 months to 6 years(mean : 2.9 years) One family of NF-2 was documented consisting of a sister a brother and their mother. Nine patients underwent operations on unilateral acoustic neurinomas : these were subtotally removed in eight patients and totally in one patient Among these patients five were deaf on the ipsilateral side at surgery. Among the other four patients with useful hearing before surgery, hearing was preserved to preoperative status in two patients. Four patients with diagnoses of meningioma, received operations to relieve mass effect with subtotal removal in two patients and total removal in the other two. Early diagnosis and treatment are the most important in the management planning of patients with NF-2 for reasons of early manifestation and rapid progression of the disease.

For the purpose of development of a liquid membrane permeator which separates metal ions from aqueous solutions continuously and effectively, a continuous membrane permeator with the membrane solution trapped between extraction and stripping phases by two micro-porous hydrophilic films was manufactured. Experimental researches on the separation of zinc ion from aqueous solutions were performed in the liquid membrane permeator with 30 vol % D_2EHPA solution in kerosine as liquid membrane. As results, the liquid membrane permeator separates zinc ion from aqueous solutions continuously and effectively in the wide range of operating conditions. A simple mass transfer rate model using equilibrium constant of the extraction reaction for the system used were proposed, and the model was compared with experimental results of separation of zinc ion in the permeator. And the effects of operating factors, such as space time, pH of extraction solution, extraction temperature, on the separation rate of zinc ion in the permeator were experimentally examined.

김수정,정규영,이용화,기창석,이남용,이상일,김지희 대한감염학회 1997 감염 Vol.29 No.4

목적: 인플루엔자는 매년 겨울 전 세계적인 유행을 일으키는 급성 호흡기 질환으로 높은 이환률과 사망율을 보인다. 국내에서도 1996-1997년 겨울철에 다수의 보고가 있었으나 아직 체계적인 감시가 이루어지고 있지 못하다. 저자들은 이 기간 동안 인플루엔자 바이러스 감염의 역학적 특성과 임상상을 연구하여 인플루엔자 감시의 기초 자료를 제공하고자 하였다. 방법: 1996년 10월부터 1997년 4월까지 삼성서울병원 임상병리과에 인플루엔자 바이러스 배양 검사가 의뢰된 모든 검체를 대상으로 인플루엔자 바이러스의 분리율과 유행 양상, 그리고 환자들의 임상상을 후향적으로 조사, 분석하였다. 결과: 총 461명의 환자로부터 525례의 검체가 의뢰되어 총 98명의 환자로부터 인플루엔자 바이러스가 분리되었다. 인플루엔자 A형은 54명의 소아 환자와 4명의 소아 환자로부터 분리되었다. 아형과 항원 특성 검사를 시행한 31례의 인플루엔자 A형 중 한 예에서 A/Wuhan/359/95 유사주로 확인되었고 12례의 인플루엔자 B형 중 5례에서 B/Guangdong/8/97 유사주로 확인되었다. 인플루엔자의 유행 양상은 3월과 4월 중순, 두 번의 인플루엔자 최고 분리 시점이 관찰되었고, 가장 많은 불리 빈도를 보인 연령층은 인플루엔자 A형의 경우 1세 미만이었고 인플루엔자 B형의 경우 3-5세였으며 폐렴이 가장 흔한 호흡기 질환이었다. 결론: 저자들은 3차 의료기관에서 분리된 인플루엔자 바이러스에 대한 역학적, 임상적 특성을 연구하였다. 지역사회에 대한 광범위한 연구가 아니므로 국내의 전반적 상황과는 차이가 있을 것으로 생각되지만 우리나라에서도 인플루엔자 바이러스의 이환률이 낮지 않을 것으로 생각되며, 보다 조직적이고 전국적인 인플루엔자 감시가 이루어져야 할 것으로 사료된다. Background: Although influenza has been a leading cause of global morbidity and mortality, we have few data regarding the epidemioloical and clinical characteristics of influenza activity in korea. Since an outbreak of influenza was recognized during winter of 1996-1997, we analysed the epidemiological and clinical features of influenza activity in the hospital seeting. Methods: All clinical specimens requested for isolation of influenza virus at Samsung Medical Center from October 1996 to April 1997 were included. Mardin-Darby canine kidney (MDCK) cell line was used for virus culture. Isolated viruses were confirmed with immunostain followed by subtyping. The demograpic and clinical characteristics of the patients were reviewed retrospectively. Results: Ninety eight influenza viruses were isolatd from 461 patients (21.3%). Influenza A and B virus were isolated from 58 (54 children and 4 adults) and 40 pediatric patients, respectively. One of 31 influenza A viruses was confirmed as A/Wuhan/359/95-like strain and 5 of 12 influenza B viruses were confiremd as B/Guangdong/8/97-like strains. Two distinctive peaks of influenza activity were recognized and the most common age of patients was less than 1 year for influenza A, and 3 to 5 years for influenza B. Common lower respiratory infections were pneumonia followed by croup, bronchiolitis and laryngitis. Conclusion: We analyzed the epidemiological and clinical features of influenza activity during winter of 1996-1997. Although this study was performed not in the community but in the hospital setting, the morbidity caused by influenza may not be low in Korea. Therefore, nationwide surveillance for influenza activity is warranted.

This paper empirically investigates the announcement effect of overseas equity related securities issuance by the 336 Korean firms between 1992 and 2001. After we reviewed the performance of overseas securities issuance firms from the existing literature, we collected data from the Korea Stock Exchange. The research was conducted by an event study. Specifically, abnormal returns are calculated by market model with parameters estimated over the 190 trading days before the event period. For each case, average abnormal returns and cumulative average abnormal returns are calculated by using daily stock returns obtained from the KSRI-Stock database. We also analyse the relation between cumulative average abnormal returns and the change of overseas securities issuance restricts, issuing size, growth opportunity by cross sectional regression. The results of this study can be summarized as follows. First, the announcement effect of overseas securities issuance is indistinct. Second, there are no particular differences of the announcement effect among overseas securities issuance firms. Third, issuing size is confirmed as a significant variable explaining cumulative average abnormal returns.

In this study we investigated the effects of supine ergometer exercise on physiological and psychological relaxation. Seven healthy young men(aged 24.4±2.00years) volunteered for the experiment. The experiment consisted of the following three successive segments" A pre-exercise period of 10 min, during which the subjects rested in a supine posture with their eyes closed for the final 5 min; an supine ergometer exercise period of approximately 10 min, during which the subjects performed intensity of 50%HRmax exercises; A post-exercise recovery of 5 min, and a recovery of 10 min, which was similar to the pre-exercise rest period. The electroencephalo-graphic(EEG) activity of the central cortex of the brain were measured pre-exercise, post-exercise 5 min, and recovery phase 10min. Fast Fourier Transformation of the EEG was used to obtain power spectrum areas in the delta(0.5~4 Hz), theta(4~8 Hz), alpha(8~13 Hz) and beta(13~30 Hz) frequencies. We compared the relative power values(power %) of the electroencephalogram alpha bands(8~13 Hz) and korean edition of the profile of mood states(K-POMS) before and after the supine ergometer exercise. We also estimated the percentage of maximal heart rate(%HRmax) throughout the experiment to ascertain the intensity of the supine bicycle ergometer exercise. The results of %HRmax indicated that the intensity of supine exercises practised in the experiments ranged from low to moderate. The power % of EEG alpha bands had increased significantly after the supine ergometer exercise compared with the pre-exercise rest(p<0.05). From the POMS results, we observed that positive mood(vigour) increased and negative mood(tension, depression, and total mood)decreased significantly after the supine ergometer exercise(p<0.05). This study found that the subjects showed increased physiological and psychological indices of relaxation after supine bicycle ergometer exercise.
