다양한 향미를 가진 막걸리의 개발을 위해 전통누룩으로부터 분리한 곰팡이로 입국을 제조한 후 품질특성을 분석하여 입국의 규격에 적합하며 이취가 없고 관능이 우수한 9균주를 입국 제조용 우수균주로 최종 선발하였다. 선발된 균주는 Aspergillus oryzae(C1-5-2-2, C20-7-3, CN1.3.1-4, CN16.19.1-1, N152-1, N220-1), Mycocladus corymbiferus (N162-2), Rhizopus oryzae(N20), Lichtheimia corymbifera (N21)로 동정되었으며, 제조한 입국의 산도는 5.0~6.8, 당화력은 128~241sp이었다. Various koji were prepared by fungi isolated from traditional nuruk and their quality characteristics were investigated. Acidity and saccharification power of their koji were ranged in 5.0~6.8 and 128sp~241sp. Nine fungi which were showed good quality and sensory evaluation were identified by analysis of their nucleotide sequences with PCR-amplified 18S rDNA internal transcribed spacer-1(ITS-1) and ITS-4 genes. Among them, six strains were identified as Aspergillus oryzae and the other strains were identified as Mycocladus corymbiferus, Rhizopus oryzae, Lichtheimia corymbifera.

As time goes up, structural capacity of members decreases in reinforced concrete structures. The deterioration of the capacity is mainly due to the corrosion of materials, poor construction and environmental pollution, etc. This deterioration is unavoidable, thus it is necessary to develop the method for repair and retrofit of structures in order to ensure structural safety of members. The purpose of this paper is to investigate the load-deflection, ultimate strength, failure mode, and energy absorption effect. For the test, the specimen size of column is 20cm×20cm×90cm reinforced with 4 number of main bars of 13mm diameter, tied bars of 6mm diameter. The test results show that the increasement of bolt and bolt tension's quantity improve the ultimate strength and energy absorption capacity.

This study was conducted to develop a simple selection method for herbicide-resistance weeds. Two methods, designated "seedling method" and "stem node method" were employed for screening of barnyardgrass against propanil and butachlor. In the seedling method, shoot and root growth of barnyardgrass were significantly inhibited at quarter of the recommended herbicide rate, while in the stem node method, the similar inhibition was obtained at half of the recommended rate. Thus, it was concluded that the seedling method is more simple and quick method to evaluate response of barnyardgrass to propanil and butachlor compared to stem node method.

Objectives : The aim of this study was to compare endogenous plasma lithium concentrations among schizophrenic patients classified by DSM-IV subtype and control groups and to investigate the correlation of endogenous plasma lithium concentration and psychotic symptoms in schizophrenia. Methods : Schizophrenic patients were selected among psychiatric inpatients without lithium medication and then classified by DSM-IV schizophrenia subtype, Schizophrenic patient groups were composed of 15 disorganized type, 15 paranoid type and 15 undilferentiated type schizophrenic patients. The control group was composed of 15 healthy subjects without any psychiatric disease,Endogenous plasma lithium concentrations were estimated by inductively coupled plasma atomic emission spectrometer. The psychotic symptoms in schizophrenic patients were classified as positive symptoms, negative symptoms and disorganized symptoms according to andreasen classificationl about SANS and SAPS items. Endogenous plasma lithium Con-centration among three subtypes of schizophrenia and control group was compared, and correlation between endogenous plasma lithium concentrations and psychotic symptoms was examined. Rcsults : 1) Schizoprenic patients showed higher endogenous plasma lithium concentration than control groups (p=0.033). Endogenous plasma lithium concentrations were significantly different among three subtypes of schizophrenia (p=0.001). Compared with the control group, disorganized type showed higher endogenous plasma lithium concentration, but paranoid type and undifferentiated type were not significantly different. 2) Disorganized symptoms correlated with endogenous plasma lithium concentration (r=0.416, P=0.004), but negative symptom and positive symptom did not significantly correlate with endogenous plasma lithium concentration (r=0.202, P=0.184. r= -0.216, P=0.155). Conclusion : These results suggested that schizophrenic patients with disorganized symptom show the differences in utilization or distribution of endogenous lithium.

난소절제후 Estrogen을 투여한 흰쥐 대동맥에서 Protein Kinase C-α와 Fas 발현의 변화

이왕수,이상엽,안지현,송영빈,김학진,이광재,유재격,김상욱,김태호,김치정,류왕성 중앙대학교 의과대학 의과학연구소 2001 中央醫大誌 Vol.26 No.3

Estrogen is believed to decrease coronary artery disease. Protein kinase C-α(PKCα)appear to be important in signal conduction pathways. Estrogen treatment increases catalytic activity of PKCα,and activation of PKCαcan modulate estrogen receptor levels and responsiveness. And it was reported that activation of PKC can protect cells from apoptosis induced by Fas ligation. But the beneficial effect of estrogen on PKCαwas not clearly demonstrated. The objective of this study was to evaluate the role of PKCαafter ovariectomy and estrogen therapy in rat aorta. The results were summarized as below: 1. The significant pathological changes were not observed in the rat aorta irrelevant to ovariectomy and estrogen therapy. 2. The expression of Fas was decreased in the aorta of estrogen-treated rats than that of ovariectomized rats without estrogen therapy. 3. Increased expression of PKCαwas more marked in the aprta of estrogen-treated rats than that of ovariectomized rat without estrogen therapy. In conclusion,PKCαmay be important in signal conduation pathway on the effect of estrogen. Activation of PKCαby estrogen reduced Fas expression, suggesting that PKCαactivation may play a role in protection against atherasclerosis. Further studies are needed to elucidate the role of PKCαafter estrogen therapy.

조류의 강세에 의존하여 조업이 이루어지는 근해안 강망어업의 어황이 조석에 따라 어떻게 변동하는지를 연구하기 위하여 1994년부터 1996년까지 주간 어획량, 조업척수, 척당어획량의 자료를 판매량이 증가하는 조금 전후와 그 반대의 현상이 나타나는 사리 등으로 구분하여 시계열분석기벅으로 장기변동추세를 분석하였다. 단계별 구분에 따른 어획량에 대한 분석결과, 3단계 구분에서 전체적으로 모형의 적합도가 가장 높게 나타났다. 3단계로 구분한 경우의 어획량은 조금에 (1-0.6891B+2.1168B²)(1-B)Z₁=(1-0.9730B)a_(?) 사리에 Z_(t)=(1+0.41659B)a_(t₁) 중간물에 (1+1.38253B+0.63391B²)Z₁-(1+1.15390B+0.64547B²)Z₁-(1+1.15390B+0.64547B²)a_(t)로 표현되었으며, 조업척수는 조금에 (1-0.19699B)Z₁=(1-0.66259B)a_(t?) 사리에 (1+0.45672B)Z₁=1+0.006094B)a_(t?) 중간물에(1.0.74814B) Z₁=((1-0.21476b)a_(t)로 표현되었다. 척당어획량은 조금에 (1-0.54709B+0.26967B^(6))Z_(t)=a_(t₁) 사리에 (1-0.26622B-0.28067B^(6))(1+0.45081B^(8))Z_(t)=(I+0.21652B^(15))a 중간물에 (1-0.23881B-0.10487B^(5))Z_(t)=a_(t)로 나타낼 수 있었다.

A seasonal Autoregressive Integrated Moving Average (ARIMA) time series model was applied to the weekly prediction of landings. number of operating boats and catches per unit effort of large stow net fisheries as ebb and flow in Korean wafers for 1994-1996. The estimated seasonal ARIMA models are presented as the fellowing equations:(1-0.6891B+2.1168B²)(1-B)Z₁=(1-(0.9730B)a₁ at the neap tides. Z₁=(1+0.41659B)a₁ at the spring tides, and (1+1.38253B+0.63391B²) Z₁=(1+1.15390B+0.64547B²)a₁ at the middle tides between the neap tide and the spring tide fer landings.(1-0.19699B) Z₁=(1-0.662593)a₁ at the neap tides. (1+0.45672B) Z₁=(1+D.0.006094B)a₁ at the spring tides, and (1-0.74814B) Z₁=(1-0.214766)a₁ at the middle tides between the neap tide and the spring tide for the number or operating boats, and(1-0.54709B+0.26967B)Z₁=a₁at the neap tides, (1-0.26622B-0.28067B^(6))(1+0.45081B^(8)) Z₁=(1+0.21652B^(15))a₁ at the spring tides, and (1-0.23881B-0.10487B^(5)) Z₁=a₁t the middle tides between the neap tide and the spring tide for the catch per unit efforts, where: :Z_(t)=the value at week t: B^(D)=a backward shift operator that is used as follows: B^(D)Z_(t)=-Z_(t-p); and a_(t)=error term at week t. The prediction error by the Box-Cox transformation on weekly landings, number of operating boats and CPUB of stow net in Korea were less than that by the Iogarithmic transformation.
