According to the analysis results on Korean cattle cooperatives, it is considered that the conditions of members' welfare, payment and education were poor because of short establishment period and unexpected financial crisis. However, the representative's farm management ability and planning was well prepared. Viewing the components of investment in the cooperative, while the proportion of investment in kind was getting bigger, investment in cash and in kind were increased by 28.6% and 78.2%, respectively compared with the beginning stage. Most of the investment in kind was destined to land and facilities. Per capita investment was increased by 11.6million won from 21.3million won at the beginning to 32.9million won. The component ratios of fixed capital such as facility and equipment were composed of 36.4% of subsidy, 43.1% of loan and 20.5% of self-support. Results of the economic analysis on the cooperatives by farming system identified that the highest profitability and productivity were achieved by Type II on increasing value-added followed by Type I of concentrating on hanwoo production, Type III on selling input and Type IV on saving input. Investment analysis based on the amount of allowable investment limit also shows that all farming systems except Type II invested over an appropriate level. Most influential factors affecting cooperative's profitability were record keeping and selling type. The effects of the cooperatives' operating system and subsidy on profitability were statistically insignificant.

Background : CD14 is the receptor for lipopolysaccharides and heat shock protein (HSP), which has been suggested being associated with increased risk of coronary artery disease (CAD). We investigated whether the response to infectious agents or HSP is different according to CD14 polymorphism in Koreans. Materials and Methods : Antibody titers to Helicobacter pylori, Chlamydia pneumoniae, and human HSP60 (hHSP60) were measured in 48 patients with stable CAD and in 41 healthy controls by ELISA. CD14 genotype was determined by PCR and high-sensitivity C-reactive protein (hs-CRP) was measured. Results : Seropositivity to C. pneumoniae and H. pylori, and antibody titer to hHSP60 were not significantly associated with the presence of CAD. CD14 genotype distribution was 31 TT (35%), 43 CT (48%), and 15 CC (17%). To compare the response to the infectious organism and hHSP60, we divided study population into 3 groups; CAD patients with non-TT genotype (group I, n=30), CAD patients with TT genotype (group II, n=18), and normal controls (group III, n=41). Seropositivity to C. pneumoniae and H. pylori, and antibody titer to hHSP60 were not significantly different among 3 groups. Though hs-CRP level was significantly different among 3 groups, post-Hoc analysis showed that hs-CRP level was not significantly different between group I and group II (group I: 1.6[1.1-3.5] mg/L and group II: 0.35[0.1-2.0] mg/L). Conclusions : This study suggests that the inflammatory responses to infectious organisms and HSP do not differ according to the CD14 genotype in Koreans. 목적 : 만성적인 세균 감염이나 자가 면역 반응이 동맥경화와 연관되어 있다는 주장이 제기되어 왔다. CD14은 lipopolysaccharides (LPS)와 heat shock protein(HSP)의 수용체로 C(-260)→T 다형성이 관상동맥 질환의 위험과 관련되어 있다고 제안되어 왔다. 본 연구에서는 한국인에서 CD14 다형성에 따른 LPS와 HSP에 대한 반응성을 염증표지자를 측정하여 살펴보고자 하였다. 재료 및 방법 : 안정형 관상동맥 환자 48명과 정상 대조군 41명을 대상으로 Chlamydia pneumoniae, Helicobacter pylori 항체 및 인체 HSP60 (hHSP60) 항체 역가를 enzyme-linked immunosorbent assay (ELISA) 방법으로 측정하였다. CD14 유전자형은 중합효소연쇄반응을 이용하여 결정하였고 hs-CRP를 측정하였다. 결과 : C. pneumonias 및 H. pylori 항체 양성 여부 및 항체 역가, 그리고 hHSP60에 대한 항체 역가는 안정형 관상동맥 질환의 유무와 유의한 상관관계는 없었다. CD14 유전자형의 분포는 TT 30명(39%), CT 31명(40%), 그리고 CC 16명(21%)이었다. 관상동맥 질환 군에서 TT 유전자형은 38%, 대조군에서는 32%로 TT 유전자형과 관상동맥 질환의 유무와는 유의한 상관관계가 발견되지 않았다(P>0.05). CD14 유전자형에 따라 C. pneumonias와 H.pylori 감염 및 hHSP60에 따른 반응에 차이가 있는지 여 부를 알아보기 위해, 관상동맥 질환 군을 다시 TT 유전자형 군과 non-TT 유전자형 군으로 나누어, 전체적으로 세군에서 항체 양성률과 역가를 비교하였다(I군: CD14 TT 유전자형을 가진 안정형 관상동맥 환자, II군: CD14 TT 유전자형을 가진 안정형 관상동맥 환자, III군: 정상 대조군). 세 군에서 C. pneumonias와 H. pylori 항체 양성률 및 hHSP60 항체 역가에는 유의한 차이가 없었다. 세 군사이에 hs-CRP 값에 유의한 차이가 있었지만, post-Hoc분석에서 II군의 hs-CRP 값이 I군에 비해 유의하게 높지는 않았다(0.35 [0.1-2.0] mg/L in group II vs. 1.6 [1.1-3.5]mg/L in group I, P>0.05). 결론 : 본 연구는 한국인에서 CD14 유전자형에 따라 LPS나 HSP에 대한 반응이 유의하게 다르지 않음을 시사한다.

Background: Hyperkalemia is a common and potentially life-threatening metabolic disorder. The electrocardiogram(ECG) is known to be a relatively sensitive diagnostic tool for hyperkalemia. However many exceptions, in which patients showed normal ECG findings even though hyperkalemic, have been reported. The purpose of this study was to determine the extent of correlation between the ECG findings and hyperkalemia and to determine when the ECG has value for diagnosing hyperkalemia. Methods: Patients who had been diagnosed as having hyperkalemia at two university hospitals during three years were enrolled in this study. We reviewed the medical records of the patients and evaluated the following 6 ECG abnormalities: tall T waves, narrow T waves, QRS widening, atrioventricular block, loss of P waves, and sine waves. We defined tall T waves and narrow T waves as 20 percentiles of heights and widths of the T waves from the 100 patients with normokalemia. Results: During the study period, there were 100 hyperkalemic patients, and we analyzed 69 available electrocardiograms. Abnormal ECG findings were revealed in 67%of 69 patients. The higher the serum potassium level, the more abnormal ECG findings. The common ECG abnormalities were tall T waves and loss of P waves. The patients with normal ECGs even though hyperkalemic had relatively low potassium levels. And whether chronic renal disease was not correlated to the ECG abnormality. Conclusion: The electrocardiogram is a good diagnostic tool for hyperkalemia if it is used with accurate diagnostic criteria. Thus, hyperkalemia should be considered when the ECG shows tall T waves or loss of P waves.

In this study, the author examined the fermentative abilities and baking properties of commercial baker's yeasts and suggested the fundamental data for the development of the yeast products industry. Carbon dioxide production, expansion abilities of doughs, and maltose fermentative abilities were measured with commercial yeasts. The fermentative abilities of various bread doughs were determined in comparison to a reference yeast and a selected yeast from commercial yeast. Various breads were prepared by these two yeasts and their sensory properties were evaluated. Y7, followed by Y5 and Y4, shooed higher ability than any other commercial yeasts in the gassing power of the dough, as measured by a Meissle fermenter. In the expansion abilities of the doughs made from various yeasts by M-Cylinder, Y7, followed by Y4 and Y5, showed the best expansion ability the results were similar to those for gassing power. Therefore, Y7 was selected. The maltose fermentative abilities of various yeasts in Atkin's liquid medium showed a higher value in Y5, Y7 and Y4. Selected yeast Y7 and the reference yeast K were used for determining the fermentative abilities of various bread doughs. For the various breads prepared by K and Y7, the qualities of the breads such as volume, weight and specific volume were measured. The volume by Y7 was higher in the straight dough bread, and that by K was higher in the sponge dough bread. In the sweet dough bread, both Y7 and K were excellent groups for it. Sensory properties of various breads made from K scored high on the items such as external properties and color in the straight dough bread. It also acquired a good score on the item of the crusts in the sweet dough bread. The overall acceptability of Y7 and K were similar.

Asbestos industry has been in operation over 60 years in Korea. However, the prevalence of asbestosis has not been yet reported. With rapid turn-over of workers, previous cross-sectional studies of current workers on the job could not find cases with exposures long enough for the development of asbestosis. This study was done to evaluate asbestosis prevalence of those worksites with operation history of more than 20 years. In total, 139 workers from 5 worksites were examined. Asbestos industries covered in the study include 2 asbestos textile, 1 brake lining, and 2 ship repairing worksites. Chest x-ray was taken from all workers and read by two experts familiar with pneumoconiosis classification according to 1980 ILO guidelines. Those with findings compatible with asbestosis were further ckecked with high resolution computerized tomography (HRCT). Pulmonary function tests were done according to ATS guidelines, and occupational and previous medical history was taken through a standardized interview. Air-borne asbestos was measured according to NIOSH method 7400. The air-borne asbestos concentrations ranged from 0.2-1.3 f/cc for asbestos textile, from 0.7-1.0 f/cc for brake lining, and from 6.3-7.8 f/cc during asbestos removal at ship repairing worksite. Of the 139 workers 25 had abnormal chest radiographic findings, and 10 of them had findings compatible with pneumoconiosis. When work history and current asbestos measurements were accounted, 9 workers who had more than 10 years of asbestos exposure history showed chest radiographic findings of pneumoconiosis with Finally, 4 workers showed finding of pulmonary fibrosis and/or pleural thickening at HRCT, and 2 of them had restrictive lung function changes. The study results showed that, among 139 subjects, there were 4(3%) definite asbestosis cases confirmed with HRCT. The prevalence of probable asbestosis was 7% for 10-14 years of exposure, 13% for 15-19 years of exposure, and 23% for 20 or more years of exposure. The prevalence of compensable asbestosis with abnormal lung function was 4-6% for those with 15 or more years of exposure.
