Dairy farming is booming now and the number of dairy cattle ha increased very rapidly in recent years. However, only a limited number of economic on dairy farm management have been done in Korea. As a fundamental data for the better utilizing the various resources concerned with dairy production, all dairy farms in Kyung-nam province were surveyed from January to February 1968. The purpose of this study was to find out the ownership of agricultural resources and farm in come of dairy farms in Kyung-nam province. The information obtained from this study will contribute to the decision making, both of individual farmers and of policy makers for dairy production. The results obtained are summarized as follows. 1. The average age of farm operator was 46 of age and variance of operator's age distribute equally in each 30, 40, 50 years of age, but a few differences are appeared among the region. 2. The farm operators educated from middle school and above level was 82.9 percent, while the farm operators educated from primary school and without school education was only 17.1 percent, but any differences are not appeared in the degree of farm operators education. 3. Dairy farm is 8.9㎞ from market or cooperative of milk apart in average, but a very high differences are appeared in regions. The carriage of milk are usually used by bicycle and bus. 4.

      • 급성 심근 경색증과 혈장 Paraoxonase activity와의 관계

        김건영,윤상준,박근호,조영신,장성종,장경식,홍순표 조선대학교 부설 의학연구소 2000 The Medical Journal of Chosun University Vol.25 No.1

        연구배경: 혈장 파라옥소나제의 감소는 HDL-cholesterol의 항 산화작용의 중요한 요소로 알려져 있어 이의 감소는 항산화작용의 저하로 인해 동맥경화의 진행을 촉진시킬 수 있어 허혈성심장병의 주요 위험인자로 추정하고 있다. 본 연구에서는 급성 심근 경색증 환자를 대상으로 혈장 파라옥소나제의 활성도를 측정하여 정상군과 비교하여 혈장 파라옥소나제 활성도의 감소가 급성 심근 경색증의 위험인자인지 알아보고자 하였다. 대상 및 방법: 급성 심근 경색증으로 입원한 39 명의 환자(남자 : 여자 = 19 : 20, 평균나이: 61±4.3세)와 정상 대조군 36명(남자 : 여자 = 17 : 19, 평균나이: 55±10세)을 대상으로 정맥혈을 채혈 후 파라옥소나제 활성도와 LDL-cholesterol, total cholesterol, HDL-cholesterol를 측정하였다. 두 군간의 비교는 Student T-test를 이용하였다. 결과: 건강 대조군과 급성 심근 경색 환자군 간에 측정치를 비교해본 결과 혈장 콜레스테롤 수치는 182.10± 12mg/dl, 194.87± 40mg/dl이고 HDL 콜레스테롤은 54±5.4mg/dl, 37.52± 13mg/dl 였다. LDL 콜레스테롤은 94.45±13mg/d1, 122±34mg/d1로 급성 심근 경색증 환자의 경우 통계학적으로 의미있는 차이를 보였다. (P<0.05). 그러나 혈장 파라옥소나제 활성도는 건강 대조군 112.35±15U/ml, 급성심근 경색증 환자군 96.10±43.50U/ml로 급성 심근 경색증 환자군이 건강 대조군에 비해 낮은 수치를 보이는 경향이 있었으나 통계학적으로 유의한 차이(P=0.071)는 보이지 않았다(Table 2참조). Background : Human plasma paraoxonase is a HDL-associated ester hydrolase that catalyzes the hydrolysis of organophosphates, aromatic carboxylic acid esters and carbamates. HDL has been implicated in the prevention of LDL lipid peroxidation. Low paraoxonase activity in the Plasma may have responsibility to the development of coronary artery disease partially because oxidized LDL has intimate relationship with atherosclerosis. We studied plasma paraoxonase activities in the plasma of acute myocardial infarction patients in order to evaluate the relationship between these enzyme activities and the acute myocardial infarction. Materials and Methods : plasma samples were obtained from 39 individuals with acute myocardial infarction(M: 19 cases, F: 20cases, mean age: 61(4.3 years) and 36 individuals of healthy control(M: 17 cases, F: 19cases, mean age: 55(10 years). We determined paraoxonase activities, total cholesterol, LDL-cholesterol &DL-cholesterol levels in the plasma samples. Paraoxonase activities were measured spectrophoto metrically in 0.1M Tris-HCl buffer (pH=7.4) at 25℃ with paraoxon as substrate(5.5mM) at 405 nm. We used student T-test to compare the results of both groups. Results : Comparison of the results between myocardial infarction patients and normal control groups revealed that plasma total cholesterol, HDL-cholesterol and LDL-cholesterol levels showed statistically significant differences between groups but plasma paraoxonase activity does not. Conclusion : Our study showed that there was no significant difference of plasma paraoxonase activity between acute myocardial infarction and normal population. So low plasma paraoxonase activity may not be a risk factor of acute myocardial infarction. but further prospective large scale study will be needed to conclude.

        자일리톨 섭취에 따른 Streptococcus mutans의 글루칸 생성관련 유전자 발현 억제효과

        김지혜,이영은,안상헌,최연희,남순현,송근배 大韓小兒齒科學會 2009 大韓小兒齒科學會誌 Vol.36 No.4

        본 연구에서는 장기적인 자일리톨의 섭취가 Streptococcus mutans의 대표적인 독성인자 중 하나인 글루칸 생성에 미치는 영향을 알아보기 위하여 글루칸 합성효소인 glucosyltansferase의 mRNA 발현을 실시간 역전사 중합효소 연쇄반응을 통해 평가하여 다음과 같은 결과를 얻었다. 1. 24개월 동안 자일리톨껌을 섭취한 군에서 타액 내 Streptococcus mutans의 colony 수는 통계적으로 유의하게 감소하였다(p<0.05). 2. 비수용성 글루칸 합성에 관여하는 유전자인 gtfB, gtfC의 발현은 자일리톨껌을 섭취한 군에서 시간이 지남에 따라 유의 하게 감소하였다(p<0.05). 특히 gtfB의 발현은 12개월과 24개월째 대조군에 비하여 통계적으로 유의하게 낮았고, gtfC의 발현은 24개월째 대조군에 비하여 통계적으로 유의하게 낮았다(p<0.05). 3. 수용성 글루칸 합성에 관여하는 유전자인 gtfD의 발현 역시 자일리톨껌을 섭취한 군에서 시간이 지남에 따라 유의하게 감소하였다(p<0.05). 또한 gtfD의 발현은 12개월과 24개월째 대조군에 비하여 통계적으로 유의하게 낮았다(p<0.05). 이상의 결과들을 종합해 보았을 때, 자일리톨의 섭취는 구강 내 Streptococcus mutans의 글루칸 합성 관련 유전자들의 발현을 억제시킴으로써 Streptococcus mutans의 수적인 감소를 가져오는 것으로 생각된다. Xylitol has the ability to reduce the adherence of Streptococcus mutans(S. mutans), which can make it easier to remove plaque, decrease acid production and inhibit dental caries. There are few reports on the effects of xylitol on the expression of the virulence related genes in S. mutans. This study examined the inhibitory effect of chewing gum containing xylitol on glucan synthesis related gene expression of S. mutans. Participants were voluntarily recruited for a women's oral health prevention program, classified into two groups(a control and a xylitol group), and then followed for 2 years. Twenty salivary samples were randomly selected from each group. Colony count and real-time reverse transcription polymerase chain reaction were used to analyze the characteristics of S. mutans. The following results were obtained: The S. mutans counts decreased steadily in the xylitol group over the study period(p<0.05). The expression of the virulence related genes (gtfB, gtfC and gtfD) was significantly lower in the xylitol group than in the control groups (p<0.05). In conclusion, these results suggest that chewing xylitol gum for a long period of time may reduce the expression of the genes associated with S. mutans virulence, which can result in a decrease growth of S. mutans colonies as a result.

        선천성 일측성 폐정맥 폐쇄증 1 예

        김철호,이계영,심영수,김건열,한용철,한성구,정희순,임정기,박재형 대한내과학회 1988 대한내과학회지 Vol.35 No.3

        Unilateral pulmonary vein atresia is a rare congenital disease and is frequently associated with intracardiac anomalies. It is usually diagnosed in childhood and is very rarely diagnosed in adulthood. A case of unilateral pulmonary vein atresia in a 20-year old female is de- scribed. The relevant findings were symptoms of exertional dyspnea, roentgenographic evidence of decreased lung volume, increased interstitial infiltration with septal lines in the involved side (right), and aoscence of blood flow in a radionuclide perfusion scan. Pulmonary angiography showed an extremely small right pulmonary artery and thining of the peripheral branches, and nonvisualization of the draining pulmonary veins. Bronchial arteriography showed rommunication between the bronchial artery and the right pulmonary artery and it was drained to the left pulmonary artery. Cardiac catheterization showed no intracardiac anomaly. The right bronchography was normal; pulmonary function studies showed a pure restrictive pattern and markedly in creased physiologic dead space. MRI showed no visible right pulmonary vein.

        디지털 및 일반 측방두부규격방사선사진에서 측정 방법에 따른 계측치의 비교

        김미자,허경회,이원진,허민석,이삼선,이진구,안병근,최순철 대한구강악안면방사선학회 2005 Imaging Science in Dentistry Vol.35 No.1

        Purpose : To compare cephalometric measurement between measuring methods in digital and conventional lateral cephalometric radiograph. Materials and Methods : Twenty digital and conventional lateral cephalometric radiographs were selected. In digital group, cephalometric measurements were performed manually using hardcopies and automatically using VCeph^(TM) program on the monitor. In conventional group, the same measurements were performed manually on conventional films, and for automatic measurement conventional films were digitized by scanner. All measurements were performed twice by 4 observers, and 24 cephalometric variables were calculated and the time spent for each measurement was recorded. The differences in measurements data and the time spent for each measurement were compared within each group. Intra-observer and inter-observer comparisons were performed. Results : In both groups, no statistically significant difference between manual and automatic measurements was observed and most of the variables didn’t show statistically significant differences between methods. The observer with less experience tended to show statistically significant differences of measurements between methods, and differences from other observers. The differences of measurements between methods in digital group were lesser than those of conventional group with statistical significance in 8 variables out of 24. With automatic method and in digital group, the spent time was shorter. Conclusion : With direct digital radiograph, automatic method using manually idenitified landmarks can be preferable in cephalometric analysis.

      • 그레이 스케일 변화량 계산에 의한 기하학적 특징 추출

        김두영,김순백,김근중 東亞大學校 附設 情報通信硏究所 1997 情報通信硏究所論文誌 Vol.5 No.1

        this paper presents a method of an edge detection and an extraction of geometric features based on computing an amount of gray scale variation. This method is derived by converting a change of gray scale between two regions of an image into a variation function that gives the difference between the gray level of each region and the gray level of the line of discontinuity. The process of computing the relative difference yields the magnitude, direction, and slope of and edge. By focusing on the relative variation of gray level for pixels between small regions, the filtering process of the local region identifies and smooths uncorrelated features for a truer edge than is possible by smoothing a larger region. We present results from the use of this feature extraction method as applied not only to visual images, but also to range and thermal images.
