This case was found in Holstein cow suffering from dystocia. The twin calves in uterus were dead and removed by fetotomy. Gross anatomical analysis of thoracopagus siamese calf was carried out. Two normal heads were present on two necks, however, the twins were fused in the thoracic region. There were four forelimbs and an abnormal orientation of ribs. Two separate vertebral columns along the length of the animal ended with two tails. A single pericardium lay on the midline when opening the thorax. However, there were two almost completely hearts within the pericardial sac. Two heart were joined by a common cavernous venous sinuous. There were two sets of lungs. Each twins had a separate esophagus that entered a separated stomach. A large liver was fused and connected into two duodenums. The pelvis, large intestines and urinary tracts were separated. The twins are female and have a full complement of limb.

The objective of this study was to investigate the calf death and analyse the causes of the mortality by based on medical records and autopsy findings during 10 years in a large dairy farm. Total of 1,361 calf born and 146 calf dead during the invested period. Mortality rate was 10.7% and showed the big difference by year-specific mortality from 2.8% (4 calves) to 19.2% (28 calves). The highest rate of mortality was 1 week age (18.5%, 27 calves) and followed by 2 week age (11.6%, 17 calves) and mortality of more old calf tended to be reduced. The death less than 4 weeks and 8 weeks of age of the entire mortality accounted for 41.1% (60/146 calves) and 70.0% (102/146 calves), respectively. Causes of calf death were digestive diseases (53.4%), respiratory diseases (17.1%), musculoskeletal disease (8.2%), and systemic disease (8.2%) in order. Specific causes of calf death was highest in enteritis (43.2%), followed by pneumonia (14.4%), sepsis (8.2%) and fractures (3.4%). Seasonally, most of calf death happened in winter (48.6%) and then fall (21.2%). This results showed that enteritis and pneumonia are the main reason of calf death but other reasons were involved in calf death on the based on autopsy finding. On going research relating factors of calf mortality is needed.

본 논문은 폐가전제품의 재활용을 위한 공동회수모형을 연구한 것이다. 이 모형은 지자체 및 생산자의 폐가전제품 수집소에 회수되어 있는 폐가전제품을 R/C(재활용 센터) 운송하는 거리를 최소화하는 것을 목적으로 한다. 현재 재활용을 위한 폐가전제품 회수물류 활동은 수집소 개별적으로 이루어지고 있어, 과도한 운송거리 및 운송비용의 초래 및 낮은 차량 적재율 등의 비효율적인 면이 존재하고 있다. 본 논문에서는 이러한 비효율적인 점을 개선하기 위해 공동회수모형을 제안하고 이를 정수계획모형과 실제 R/C의 입고자료를 이용하여 그 효과를 분석했다. In this paper, we studied about an consolidated transportation model to transport EOL (end-of-life) electronic household appliances for recycling in South Korea. The objective is to minimize the total traveling distance of the vehicles transporting EOL electronic household appliances collected by local authorities and major manufacturers' distribution centers to assigned R/C(recycling center) in South Korea. Current reverse logistics for recycling EOL electronic household appliances is operated by local authorities and major manufacturers individually, and it is inefficient for the following reasons: excessive traveling distance, transportation cost, low truck capacity utilization, and so on. The presented model is developed to solve this problem. We apply a integer programming to solve this problem and present computational results using actual field data.

The effect of grain size on the deformation induced martensite transformation and mechanical properties in austenitic stainless steel with high amount of Mn was studied. a`-martensite was formed by deformation and deformation induced martensite was formed with surface relief. With increase of grain size, volume fraction of deformation induced martensite was increased. With the increase in degree of cold rolling, hardness, and tensile strength was rapidly increased with linear relationship, while, elongation was decreased rapidly and then decreased slowly. With increase of grain size, hardness and tensile strength was rapidly increased with linear relationship, while elongation was decreased rapidly. The hardness, tensile strengths, and elongation were more strongly influenced by deformation induced martensite than the grain size.

The present study was undertaken to establish reference values for the composition blood lymphocyte populations and compare forty three Hanwoo neonatal calves (KC) with twenty one Holstein calves (HC) by blood cell count and immunophynotying. The percentages of CD2+, CD4+, CD8+, CD26+, ACT2+, MHC class, MHC class II and WC1+ T cells, B cells were determined by flow cytometry. The number of lymphocyte and monocyte in HC were higher than those of KC. However, the number of neutrophils was higher in HC than KC. The proportions of CD2+, CD4+, CD8+, MHC class, and WC1+ lymphocytes remained relatively stable during the study period, while there was a moderate increase in the relative percentage of CD26+, ACT2+, MHC class II and B cell from birth to approximately 3 weeks of age. Marked differences in the relative proportions of the lymphocyte subpopulations were noted between the individual calves. The present study shows that the T-cell subpopulations are present in peripheral blood of KC at levels comparable with HC, while the MHC class II and B cell population of KC increases significantly with age. The absolute number of WBC in KC was due to the decrease of absolute number of neutrophil rather than the increase of lymphocyte. The results indicated that KC have significantly higher number of neutrophils, and proportion of MHC class II and B cell than HC.

본 연구는 임상형 혹은 준임상형 자궁내막염에 이환된 젖소와 자궁내막염이 발생되지 않은 젖소 사이에 분만 전 후 기간 동안 혈액 대사물질의 농도를 비교하였다. 분만 전 4주, 분만 후, 분만 1, 2, 4, 6주 후 혈액을 채취하였으며, 혈청 분리 후 calcium, magnesium, non-esterified fatty acids (NEFAs), total cholesterol, albumin, urea nitrogen, ${\beta}$-hydroxybutyrate (BHBA), aspartate aminotransferase (AST), ${\gamma}$-glutamyltransferase, glucose 및 phosphorus 농도를 측정하였다. 분만 후 4주에, 임상형 혹은 준임상형 자궁내막염 발생 유무에 따라 대조군(n = 104), 임상형 자궁내막염군(n = 66) 및 준임상형 자궁내막염군(n = 37)으로 구분하였다. Calcium과 magnesium 농도는 실험 전 기간에 걸쳐 임상형 자궁내막염군이 대조군과 준임상형 자궁내막염군에 비해 낮았으나(p < 0.05 to 0.0001), NEFAs 농도는 실험전 기간에 걸쳐 임상형 자궁내막염군이 대조군에 비해 높았다(p < 0.01). Total cholesterol 농도는 분만 전 및 분만 후 기간 중 임상형 자궁내막염군이 대조군과 준임상형 자궁내막염군에 비해 낮았다(p < 0.05 to 0.001). Albumin 농도는 분만 후 기간 동안 임상형 자궁내막염군이 대조군과 준임상형 자궁내막염군에 비해 낮았다(p < 0.05 to 0.001). Urea nitrogen 농도는 분만 후 4주 및 6주에 임상형 자궁내막염군이 대조군과 준임상형 자궁내막염군에 비해 낮았다(p < 0.01). 분만 후 1주에, BHBA 농도는 임상형 자궁내막염군이 대조군에 비해 높았으나(p < 0.01), AST 농도는 임상형 자궁내막염군과 준임상형 자궁내막염군이 대조군에 비해 높았다(p < 0.05). 결론적으로, 분만 후 혈청 calcium, magnesium, total cholesterol, albumin 및 urea nitrogen 농도의 감소와 NEFAs, BHBA 및 AST 농도의 증가가 임상형 자궁내막염의 발생과 관련되었으며, 이것은 전환기 중의 균형 잡힌 영양의 중요성을 제시한다. This study compared blood metabolites during peri- and postpartum periods among cows with clinical or subclinical endometritis and cows without endometritis. Blood samples from 207 Holstein dairy cows were collected at 4 weeks prepartum, just after calving, and at 1, 2, 4, and 6 weeks postpartum to measure serum concentrations of calcium, magnesium, non-esterified fatty acids (NEFAs), total cholesterol, albumin, urea nitrogen, ${\beta}$-hydroxybutyrate (BHBA), aspartate aminotransferase (AST), ${\gamma}$-glutamyltransferase, glucose, and phosphorus. Clinical endometritis was diagnosed by the observation of vaginal discharge (> 50% pus) and subclinical endometritis was diagnosed by the evaluation of uterine cytology (> 18% neutrophils) at 4 weeks postpartum. Cows were divided into three groups based on the presence or absence of clinical or subclinical endometritis: the control group (n = 104), the clinical endometritis group (n = 66), and the subclinical endometritis group (n = 37). Calcium and magnesium concentrations were lower in the clinical endometritis group than in the control and subclinical endometritis groups throughout the study period (p < 0.05 to 0.0001), whereas the NEFAs concentration was higher in the clinical endometritis group than in the control group throughout the study period (p < 0.01). The total cholesterol concentration was lower in the clinical endometritis group than in the control and subclinical endometritis groups throughout the pre- and postpartum periods (p < 0.05 to 0.001). The albumin concentration was lower in the clinical endometritis group than in the control and subclinical endometritis groups during the postpartum period (p < 0.05 to 0.001). The urea nitrogen concentration was lower in the clinical endometritis group than in the control and subclinical endometritis groups at 4 and 6 weeks postpartum (p < 0.01). At 1 week postpartum, the BHBA concentration was higher in the clinical endometritis group than in the control group (p < 0.05), whereas the AST concentration was higher in the clinical endometritis and subclinical endometritis groups than in the control group (p < 0.05). In conclusion, lower serum concentrations of calcium, magnesium, total cholesterol, albumin, and urea nitrogen, but higher concentrations of NEFAs, BHBA, and AST during the postpartum period were associated with the incidence of clinical endometritis, indicating the importance of balanced nutrition during the transition period.

This study was carried out to investigate the effect of reverse transformation on the mechanical properties in high manganese austenitic stainless steel. Over 95% of the austenite was transformed to deformation-induced martensite by 70% cold rolling. Reverse transformation became rapid above an annealing temperature of 550℃, but there was no significant transformation above 700℃. In addition, with an increasing annealing time at 700℃, reverse transformation was induced rapidly, but the transformation was almost completed at 10 min. There was a rapid decrese in strength and hardness with annealing at temperature above 550℃, while elongation increased rapidly above 600℃. At 700℃, hardness and strength decreased rapidly, and elongation increased steeply with an increasing reverse treatment time up to 10 min, whereas there were no significant change with a treatment time after 10 min. The reverse-transformed austenite showed an ultra-fine grain size less than 0.2 ㎛, which made it possible to strengthen the high manganese austenitic stainless steel.
