淺水灣 북부지역 양측 연안에서 이제까지 보고되지 않은 새로운 퇴적층이 발견되었다. 이 퇴적암은 선캠브리아기의 低變成堆積岩(泰安層)과 쥬라기 黑雲母花崗岩으로 구성된 基盤岩을 不整合으로 덮고 있으며 천수만의 윤곽을 나타내므로 淺水灣層으로 명명할 것을 제안한다. 본 천수만층은 역암, 응회암, 현무암, 응회암질 각력암, 셰일로 구성되어 있으며 천수만의 북서부와 북동부의 연안과 중앙부인 죽도 등지에 걸쳐 분포한다. 생성시기는 중생대 말기로 추정된다. 전체 분포 양상이 이곳에 발달한 남북방향의 구조선과 일치하며 여기에 따른 단층작용, 및 화산작용과 밀접한 관련을 갖고 퇴적된 결과로 해석되었다. 이들의 퇴적은 서측에서 동으로 이동하면서 이루어졌다. A previously unreported sedimentary complex has recently been discovered in the northern part of Choˇnsu Bay. It overlies both unconformably the Precambrian low-grade metamorphosed sedimentary sequence(Taean Formation) and the Jurassic biotite granite. The sedimentary complex is proposed to be designated as Choˇnsuman Formation. The Formation is composed of conglomerate, tuff, basalt, tuffbreccia, and shale. It is distributed in the northwest and northeast coasts of Choˇnsu Bay and in the Chukdo. Age of the Formation seems to be of late Mesozoic. The Choˇnsu sedimatary basin is considered to be originated by block faulting presumably during the Cretaceous, as suggested by the development of N-S trending structural lineation in the study area and its vicinity. The Choˇnsuman Formation seems to be formed by sedimantation in close association with block faulting and volcanic activities nearby. Sedimentation is thought to be developed from west to east in the basin.

The Kongju basin of Cretaceous sedimentary rocks, which is located in the area between Ogcheon fold belt and Gyeonggi massif, is developed by the strike-slip fault and shows elongated rhombic shape trending roughly NE and SW with about 4㎞ in width and 25㎞ in length. Two stripes of ductile shear zone are traced in basement rocks along the boundary of basin. The shear sense of ductile shear zone is suggested to be sinistral. The Cretaceous sedimentary rocks within the Kongju Basin also exhibit deformed state in terms of developments of en-echelon arrayed folds, faults and various kinds of joint systems. The majority of joints is occupied by the fractures whose strikes are approximately normal to the directions of en-echelon arrayed fold axes. The shortening(α^(-1)) of fold system is most pronounced at the central part of the basin and gradually decreases toward both ends of the basin. Both of the strikes of fold axial planes and the azimuths of fold axes change discontinuously to form sigmoidal style of en-echelon arrayed folds. The en-echelon arrayed folds, all plunged towards SW direction, indicate that upper layers of the sedimentary rocks are more distributed in the SW area of the basin than in its NE area. The gravity anomaly around the Kongju basin shows 12∼17 mgal in the outer metamorphic zone and 8∼10 mgal in the basin; and its minimum value occurs in NE-SW direction along the western boundary of the sedimentary basin. The electric resistivity study on both boundaries of the basin shows 200∼300Ω-m in the boundary zone, 500∼600Ω-m in sedimentary rocks, and 1000Ω-m or more in the granite-gneiss region. These values indicate that the east boundary be gentle slope and the west one be steep fracture zone. 'These patterns of geophysical data implicates that the Kongju sedimentary basin should be dipping down to the west.

Background: Hepatitis B virus (HBV) infection is one of the worldwide public health problem affecting about 300 million people. The envelope protein of HBV consists of three components known as preS1, preS2, and S antigen. According to the recent study, anti-HBs Ab showed effective neutralization ability against HBV from chronic hepatitis B and liver transplant patients, suggesting the possible development of therapeutic antibody. Methods: Spleen cells immunized with S antigen of HBV were fused with myeloma cell line to obtain HBsAg specific monoclonal antibodies. High affinity antibodies against HBsAg (adr, ad and ay type) were selected by competitive ELISA method. Nucleotide sequence of the variable regions of monoclonal antibodies was analyzed by RT-PCR followed by conventional sequencing method. Results: We produced 14 murine monoclonal antibodies which recognize S antigen of HBV. Two of them, A9-11 and C6-9 showed the highest affinity. The sequence analysis of A9-11 revealed that variable regions of the heavy chain and light chains are members of mouse heavy chain I (B) and light chain lambda 1, respectively. Likewise, the sequence analysis of C6-9 revealed that variable regions of the heavy chain and light chains are members of mouse heavy chain II (B) and light chain kappa 1, respectively. Neutralization assay showed that A9-11 and C6-9 effectively neutralize the HBV infection. Conclusion: These results suggest that A9-11 and C6-9 mouse monoclonal antibodies can be used for the development of therapeutic antibody for HBV infection.

b値 算出과 그 差異 解析에 관한 硏究

宋武永 忠南大學校 環境問題硏究所 1985 環境硏究 Vol.3 No.1

For the regression analysis such as b value in the Gutenberg- Richer relation, Least Square Estimation and Maximum Likelihood Estimation were mathematically reviewed. From the NOAA-EDIS earthquake data file, we calculated the b value in the adjacent to the Korean Peninsula as 0.723 and the East Sea side shows lower value than the Northwest side. The b value of the microearthquakes in the Southeast region of the Korean Peninsula was reviewed. In most cases, there are the b value differences between LSE and MLE for the same data and the differences have no relation with the correlation coefficients and the earthquake total frequencies. The difference will be due to the different assumption for the object data as the Gaussian distribution. Therefore the b value calculation needs everytime the definition of the estimation methods for the b value comparison in space and time.

한반도 중부권 지각물질의 구조와 물성연구(2) : 퇴적암류 코아시료의 탄성파 속도와 점재하 강도 비교

송무영,황인선 대한지질공학회 1993 지질공학 Vol.3 No.1

석회암, 사암과 셰일의 퇴적암 코아시료를 대상으로 암석의 비중, 공극률, 함수율 등을 구하고 탄성파 전파 속도와 점재하 강도 지수를 측정하였다. 이들 암석물성 사이의 관계로부터 석회암에 대한 밀도와 탄성파 속도의 관계는 $Vp=4085d^2-20747d+303,{\;}V_s=3899d^2-21442d+318$의 다소 곡선 경향을 나타낸다. 또한 밀도가 높은 셰일의 탄성파 속도가 사암에서보다 작으며 이는 셰일의 층리 영향띠문인 것으로 보인다. 석회암, 사암, 셰일의 P파 속도와 S파 소ㄷ도는 대체로 직선 양상을 보여주며 각 관계식은 석회암에서는 $V_s=0.26V_p+1041.6m/sec,{\;}사암은{\;}V_s=0.43V_p+424.2m/sec$, 셰일에서는 r= 0.86으로 나타났다. 석회암에 대한 점재하 강도 시험에 의하면 점재하 강도 이방성을 시료가 다소 호상구조를 보이더라도 뚜렷하지 않았다. $30^{\circ}-60^{\circ}$내외의 변화를 보이는 층리면 경사각은 직경방향과 축방향의 점재하 지수에 큰 영향을 미치지 않은 것으로 생각된다. 점재하 강도 실험결과 점재하강도 지수가 증가하면 P파 속도도 증가하지만 상관관계가 뚜렷하지 않았다. In order to investigate the correlation of sedimentary rock properties. specific gravity, porosity, water content, sonic wave velodty, and point4oad strength index of core samples of limestones, sandstones and shales were measured. The relationships between density and velocity show $V_p=16300d-38719.3,{\;}V_s1896.4d-29225.1$ of regression equation for sandstones and $Vp=4085d-10264.8,{\;}V_s=3519d-7841.3$ for shales and <$Vp=4085d^2-20747d+303,{\;}V_s=3899d^2-21442d+318$ for limestones. Seismic wave velocity of shales which have high density is lower than that of sandstones, and this seems to be an effect of bedding in shale. P-wave velocity and S-wave velocity of limestones, sandstones and shales show the linear relationships as a whole. The regression equations are respectively calculated V_s=0.26V_p+1041.6m/sec,{\;}V_s=0.43V_p+424.2m/sec,{\;}and{\;}Vs=0.51V_p+261.9m/sec$ and the correlation coefficients of the velocity show r= 0.86 in sandstones, r= 0.75 in limestones and r=0.86 in shales. According to the point4oad strength test for limestones, point4ord strength anisotropy was not so dear even though the specimens show generally the banded structure. Variations of dip angle of bedding whihin the range $30^{\circ}-60^{\circ}$ does not have much influence upon the diametral strength index and axial strength index. From the result of point load test, P-wave velocity increases with point4ord strength index but the regression equations are $V_p=98.5lI{s_d}+4082.1m/sec,{\;}V_p=106.41{s_a}+3954m/sec$ and their correlation coefficient is low.

연약지반에서의 P파와 S파의 반응비교 연구

송무영,유영준 충남대학교 기초과학연구소 1994 연구논문집 Vol.14 No.-

瑞山 干拓地의 연약지반과 大田 근교의 논의 토양에서 P파와 S파의 직접파 및 굴절파 반응시험을 실시하였다. SH파 탐사는 평판 측면타격에 의한 두 가지 極性의 진원과 3성분 수진기 및 12ch의 Enhancement Seismograph로 수행되었다. 실제적인 실험결과 대못의 목재 직각평판의 소규모 탐사 시험에 가장 편리하였고, 타격용 鐵球의 무게는 에너지의 크기 및 사용의 편리성을 고려할 때 30㎏ 정도가 적합하였고, 지반과 평판의 結合(coupling)증진과 SH파의 발생을 위한 최적하중은 200㎏으로 나타났다. 신호의 重合(stacking) 회수는 3회 이상일 때 SH파 탐지의 最適 移隔距離(optimum offset)는 6m부터 30m 범위이었다. SH파의 판별은 極性變化를 이용하였으며 3성분을 X, Y, Z로 하고 [타격방향/수진방향]의 기호로 표시할 때 [+Y/Y]와 [-Y/Y]에서만이 극성변화 구분이 수월하였다. SH파 속도는 P파에 비하여 1/2∼1/4 범위이며 Poisson비는 0.35∼0.47 범위로 산출된다. Poisson비의 값이 큰 것은 서산 간척지의 연약지반으로서 층후는 15∼22m의 범위이며 비저항치는 3∼10Ωm의 범위를 보이므로 海水로 포화된 泥質 堆積物로 추정된다. 大田 근교의 논 토양의 Poisson비는 비교적 낮은 값을 보여준다. The responses of P wave and S wave were measured in the soft ground of Sosan reclamation area and in the paddy soil near Taejon. The SH wave exploration was carried out with plate striking source of opposite polarities, 3-component geophones and enhancement seismograph of 12 channels. The optimum condition for SH wave generation was known: ① rectangular wood plate with spikes, ② striking steel ball (30㎏) of pendulum type, ③ 200 ㎏ weight for coupling between ground surface and wood plate. With the 3 times for stacking using hammer blow, the observable offset for SH wave was 6m through 30m. With steel ball pendulum, 70m is possible. The identification of SH wave signal was based on the polarity change, and 3-component signal comparison (X, Y, Z). [Striking direction/receiving direction] was used, and [+Y/Y] and [-Y/Y] made the polarity change with weak energy. The P wave velocity was 2∼4 times of that of SH wave, then the Poisson's ratio was calculated in the range of 0.35∼0.47. The soft ground with high Poisson's ratio was found in the depth 15∼22m of Sosan area, and their resistivity was 3∼10Ωm. Therefore the layer was interpreted as the mud layer saturated by sea water. The paddy soil in Taejon showed the low Poisson's ratio.
