        牧楡湯이 人體 肺癌細胞의 變化에 미치는 影響에 關한 分子生物學的 硏究

        李炯周,金相贊,徐富一,金先熙,卞晟僖 대한본초학회 1999 大韓本草學會誌 Vol.14 No.1

        This experimental study was performed to investigate the effects of Mokyou-Tang on cell cycle and gene expressions of human lung cancer cell. I examined the cell cycle progression and cell cycle-related gene expression in A549 using a flow cytometry and a quantitative PT-PCR analysis. The treatment groups, in accordance with concentration of Mokyou-Tang were classified as 3 group(MYT 100㎕/㎖, MYT 500㎕/㎖, MYT 1,000㎕/㎖), and according to treatment time, were classified as 2 group(24hours, 48hours). The results were summarized as follows; 1. In cell cycle stage, MYT 100㎕/㎖(48hours) and 1000㎕/㎖(48hours) groups were increased as compared with control group, especially 1000㎕/㎖(48hours) group showed eminent increase. 2. In p53 gene, MYT 500㎕/㎖(48hours) and 1000㎕/㎖(48hours) groups showed eminent suppressive effect to cancer cell. 4. CDKNI gene was decreased in all treatment groups, this mean that MYT has suppressive effect to proliferation of cancer cell. 4. In GADD45 gene was decreased in all treatment groups, this mean that MYT has suppressive effect to proliferation of cancer cell. The results suggest that MYT promotes G1 cell cycle arrest and suppresses the proliferation of cancer cell. Thus, it seems likely that MYT has suppressive effect to proliferation of lung cancer cell.

      • RFM을 이용한 고해상도 위성영상의 기하보정에 관한 연구

        전형섭,정용주,조기성 전북대학교 공학연구원 ( 구 전북대학교 공업기술연구소 ) 2003 工學硏究 Vol.34 No.-

        Manufacturing of the large scale map using the high-resolution satellite data requires high-precision geometric correction, and for this the location ephemeris data as like the location and attitude of the satellite sensor, which is an orbit component model, is needed, but in IKONOS satillite these are not porvided because of the business technology protection. Therefore, in this study, as the basic course for obtaining the ground coordinates from the IKONOS satellite imagery, using the ground control point without the satellite aid data it derived RMF's coefficient in the geometric correction of high-resolution satellite imagery, did the geometric correction using RFM and evaluated accuracy, and then finally it could be gotten the follwing conclusion as the result of evaluating the RMF's usefulness. First, as the result of applying to the least square method, to derive the coefficient of RFM using the ground control point, in the case of using the third order expression, it could derived the exact coefficient value about 0.686 pixel(m) of the root mean square error. Second, as the result of comparing the polynominal expression model and RFM, by using RFM it could improve the root mean square error more than 1.5 pixel. Third, RFM is very sensitive to the Z value information, and it could know that using the polynominal expression is more efficient than RFM is if the Z value infromation is inaccurated.

      • 18세기 말 전라도 수군전법 변화의 특성 : 전라우수영『전지도첩』과 전라좌수영『수조홀』을 중심으로

        장원주,최형주 龍仁大學校 武道硏究所 2011 武道硏究所誌 Vol.22 No.1

        이 연구는 18세기 말에서 19세기 초에 작성된 전라도수군의 군사훈련과 관련된 2종의 자료를 중심으로 18세기 말 전라도 수군전법 변화의 특성을 살펴보기 위해 작성되었다. 당시 수군제도의 전략적 재편과 수군전법의 전술적 보완이 요구되고 이에 따라 변화하던 수군편제를 살펴볼 수 있는 것 중 하나가 바로 수조다. 임진왜란 이후 중국의 수군전법을 받아들여『兵學指南』의 수조를 정비한 조선은 18세기에 이를 더욱 보완해 『兵學通』수조의 완성을 보았고, 이 시기를 전후하여 각 지역의 일선 수군지휘관들에 의해 수조홀기류 문서들이 작성되기 시작하였다. 이 자료들 중 전라도의 수군전법을 보여주는 것이 전라좌수영『水操笏』과 전라우수영『戰陣圖帖』이다. 전라우수영『戰陣圖帖』에는 총 12가지의 진도가 수록되어 있다. 이 진도들은 1780년 이전의 7개 진도와 이후의 5개 진도로 나눌 수 있다. 두 부류의 진도에 나타나는 전라우수영의 진관 편제는 확연히 다르며, 진형 역시 그 성격이 크게 달라 18세기말 전라우수영 전법의 변화를 뚜렷이 살펴볼 수 있게 해준다. 1830년대에 작성된 것으로 추정되는 전라좌수영『水操笏』은 총 8부분으로 나뉘어져 있다. 수군군사훈련의 핵심내용을 담고 있는 첫 번째「水操笏」과 두 번째의「夜操笏」은『兵學通』의 수조절차를 대부분 요약하면서도 절차와 의례에 중점을 두고 있었다. 즉『水操笏』은『兵學指南』과『兵學通』의 형식과 절차를 그대로 따르면서도 조선적인 특색을 띄고 있다 할 수 있겠다.

        소아복부둔상시 저혈량성 쇽과 연관된 복부전산화 단층촬영술의 유용성

        박광철,조수형,조남수,박진,변주남 대한응급의학회 2000 대한응급의학회지 Vol.11 No.4

        Background: We reviewed retrospectively the clinical features and contrast material-enhanced computed tomography(CT) after blunt abdominal trauma demonstrated a characteristic hypoperfusion complex. Our purpose were to evaluate the hypothesis that children with this "hypoperfusion complex" CT finding were associated with a tenuous hemodynamic state, severe injury and a poor outcome. Methods: Between January 1996 and December 1999, 39 consecutive children who sustained blunt trauma and were suspected clinically of having intraabdominal injury underwent CT. Demographic data, blood pressure, indication for CT, pediatric trauma score(PTS) and Glasgow coma score(GCS) were recorded at the time of the initial examination. Results: Three of the 39 children(8%) demonstrated a characteristic finding at CT which was described as the hypoperfusion complex. The "hypoperfusion complex" was present in the 3 of the 39 traumatized children(8%), but was the main radiographic finding in the 3 of the 14 children with a severe pediatric trauma score(PTS<8) and in the 3 of the 6 children with a Glasgow coma score(GCS<8) who were examined with CT. Conclusion: The CT findings in all children with the hypoperfusion complex by definition included marked, diffuse dilatation of the intestine with fluid; abnormally intense contrast enhancement of the bowel wall, mesentery, kidney and/or pancreas; decreased caliber of the abdominal aorta and inferior vena cava(IVC); and moderate to large peritoneal fluid collection. This "hypoperfusion complex" is a relatively rarely observed in injured children but appears to be associated with severe injury and a poor outcome. The pediatric trauma score provides a useful profile of injury severity in children. Prompt diagnosis of hypovolemic shock is important so that supportive therapy can be instituted to prevent further metabolic abnormalities and their potential cardiotoxic effects. In summary, the intense multiorgan enhancement pattern seen in the hypoperfusion complex indicates tenuous hemodynamic stability and is associated with a poor outcom.

      • 고립성 폐결절의 조직학적 진단에 있어서 경기관지폐생검의 진단적 가치

        김치훈,김정주,왕준호,연규민,김형수,리원연,용석중,신계철 건국대학교 의과학연구소 2002 건국의과학학술지 Vol.12 No.-

        Transbronchial lung biopsy(TBLB) is a relatively simple and convenient diagnostic tool in solitary pulmonary nodule(SPN) on chest radiograph, which is cannot be diagnosed through routine tests. To investigate the diagnostic value and diagnostic rate of TBLB according to the variable factor, we analyzed 69 patients with radiologically SPN lesion on chest radiograph which was confirmed histologically. A histologic diagnosis of TBLB was made in 47 of 69 patients(68.1%), in which 26 of 37(70.3%) with malignancy and 21 of 32(65.6%) with benign lesion. There were no significant differences in diagnostic yield according to age, sex and location of the lesion. The diagnostic rate tended to increase with the more than 5 pieces to acquired by TBLB. When the size of SPN was less than 3 ㎝, it cannot be diagnosed. In conclusion, TBLB is a diagnostic procedure with good yield and safety, but percutaneous needle aspiration, transbronchial needle aspiration, and bronchial washing fluid cytology may be a complementary procedure to overcome the limitation of TBLB and get higher diagnostic yield for SPN.

      • 鉛暴露 作業者의 鉛中毒 早期發見을 위한 集團檢診法 改善方案에 관한 硏究

        홍대용,김장락,정주화,최현림,윤형렬 慶尙大學校 1995 論文集 Vol.34 No.1

        This study was carried out to evaluate the feasibility of current lead indicators used in screening lead who were sspeted to have been exposed to lead were selected as 'case'and 207 female workers from non-lead industry were selected for 'control'. The results obtained were as follows: 1. The mean values of blood lead for case and control were 31.4㎍/dl, 22.2㎍/dl,respectively. The difference observed in the mean concentration between case and control was statistically signifi-ant(P<0.01) 2. The mean values for blood ZPP by hematofluorometer for case and control were 31.3㎍/dl, 25.4㎍/dl,respectiely. And difference between two groups was statistically significant(P<0.01). 3. No statistically significant correlation was found between working duation and blood lead, blood ZPPlovel. 4. According to the simple correlation analysis,ZPPand urine lead were found to be statistically correlated with blood lead(P<0.01) 5. According to the discriminant analysis using blood lead as a dependent variable, it showed 89.1% predictability when using 40㎍/dl as a cutting value which is used as a screenig cutting value for industry workers health examination, while 81.8% for 30㎍/dl,77.54% for 20㎍/dl, respectively. 6. Lead related simptons which is used for screening the lead ntoxicated patients were used as a dependent variables in multiple regression analysis to find useful lead indicator. And significant independent variables were found to be ZPP, Age, and Hct. 7. Above results suggest that objective evalution of feasibbility of several lead indicators should be developed to correct the disutility of current lead screeng system in Korea.

      • MgO 버퍼층을 이용한 PZT 박막의 형성 및 특성 평가

        김지미,전호승,강재경,최형봉,김철주 서울시립대학교정보기술연구소 2001 정보기술연구소 논문집 Vol.3 No.-

        In this paper, we fabricated the MgO layer by sol-gel method and estimated possibility as a buffer layer for ferroelectric such as PZT. MgO(Magnesium Oxide) proposed as buffer layer of ferroelectric is already for much used as buffer layer in optic technology. There are many formation methods of MgO layer, but in this study, we selected the sol-gel method which is easy to control the content of material and possible for fabrication of uniform layer, then we formed thin layer through the composition of MgO and PZT solution, spin coating and annealing. To estimate the possibility as buffer layer about ferroelectric layer, we analyzed the physical and electrical characteristics about PZT on MgO layer.By SEM, AFM and XRD analysis, we could know facts that the surface condition of PZT on MgO was relatively smooth and the crystal orientation of PZT was enhanced by MgO layer. Due to the measurements of P-V, C-V and I-V characteristics of PZT/MgO capacitor structure, the polarization, fatigue and breakdown properties of PZT on MgO were much improved than those of PZT without MgO layer. Also, in MFIS structure, the PZT on MgO showed the stable memory property. These results could be compared to those of MgO buffer layer formed by sputtering, so, if studies about the composition of MgO solution and the formation of MgO layer are executed continuously, the fabrication process of MgO layer by sol-gel method can be applied as the process for buffer layer of ferroelectric.

      • 都市街路의 遲滯度推定에 관한 硏究

        임채문,권강훈,이주호,김태형 대구대학교 과학기술연구소 2001 科學技術硏究 Vol.8 No.1

        This study suggested input variables whose effects have been considered by adjusting various input variables in the TRANSYT-7F and NETSIM, the Simulation programs employed in calculating the delay time at street sections. The results can be summarized as follow. 1. Among the input variables in the TRANSYT-7F needed to calculate the delay time at street sections, the excluded are those which effect the most on time delay, such as bus stops, pedestrian crossings and on/off ramps. Among the input variables the most affecting factors are Saturation flow rate and time delay whose suggested quotients are well summarized in the text of this study. 2. There are variables which affect the change of time delay in the NETSIM, such as bus stop, pedestrian crossing, bus appearance period, and departure time delay. This study did the Simulation program using those variables except pedestrian crossing because, as the result of the correlation analysis suggests, there is a strong correlation between bus stop and pedestrian crossing. In this study, the survey had been done in the morning and afternoon except the Peak time, so heavily congested sections were excluded. And both sides of three street sections were surveyed. Therefore, there should be further studies on heavily congested situations and many other street sections.
