A diesel engine for tractor was tested for 250 hours of durability with biodiesel fuel of 100%. An engine test cycle was designed based on the ISO test code of off-road vehicle. Eight test conditions, combination of three engine speeds and eight engine loads, were applied to the engine endurance test, and the engine was operated for eight hours in a day. Power output, fuel consumption rate, exhaust gas quality and particulate matter （Pm） were measured and discussed. For the extensive 250 hours of the tractor diesel engine endurance test no significant changes of power output, fuel consumption rate, exhaust gas quality and Pm were monitored and authors could not find any difference in the engine patterns of the two fuels of BDF100 and light oil. During all the engine endurance test conditions, no abrupt stopping was encountered but because of temperature down by the cold season the endurance test could not carried out for some periods. Pms were collected and the average F＇m was 0.027 g/kw which was far below than Tier 4 diesel engine Pm of 0.3 g/kw h defined by US EPA Pm of the diesel engine clas,;. Overall even 100% biodiesel can be an alternative fuel for light oil for diesel engine operation with some considerations for cold sea：son use.

目的利用倾向评分匹配法探讨乳腺浸润性小叶癌(ILC)病人术前乳腺mR成像与手术预后的关系,以确定mRI检查是否对乳腺癌ILC亚型有益。材料与方法 2005年1月—2016年12月期间接受手术的603例ILC病人,其中369例(61.2%)行乳腺mRI检查。本研究对mRI发现但乳腺钼靶和超声检查中未发现的病变进行统计,并分析术中因疾病情况作出的改变。在倾向评分匹配后,将196例病人分成mR组和非mR组,并平衡两组间与病人、肿瘤特征以及各种临床特征有关的17个可能的混杂变量。比较2组手术结果。结果 369例接受mRI检查的病人中,145例(39.3%)发现其他病变,这145例病人中有95例(65.5%)发现恶性病变。在369例病人中有94例(25.5%)因mRI检查结果而改变手术方式。根据病理结果显示,这94例病人中84例(89.4%)手术方式的变更是合理的。在倾向评分匹配分析中,与未进行乳腺mR成像病人相比,乳腺mRI检查与较低重复手术率相关(比值比,0.140;PmRI检查提高了乳腺恶性肿瘤的检出,在不增加乳腺切除率的同时可以显著降低重复手术的可能性。

In order to elucidate the state of diseases, especially viral diseases, and to prevent viral diseases from occurring in olive flounder hatcheries, a range of studies, including epidemiological study, were performed from 1997 to 2003. The location of the hatcheries investigated includes several representative sites in the east （Kangnung, Uljin, Pohang, yangsan, Ulsan, Pusan）, south （Wando, Changheung, Goheung, yeosu, Namhae, Tongyeong, Geoje, jeju） and west （Seosan, Kunsan, Gochang, yeongkwang, mokpo, Chindo） costal areas of the Korea Peninsula. A total of 2000 cases have been examined in 7 years, in which mortality caused by viral agents accounts for 22%, or 446 cases. mortalities associated with viral infection considerably increased from 14% in 1997 to 27% in 2003. A variety of viral diseases were observed, and the occurrences of viral epidermal hyperplasia, viral ascites and viral deformity, viral nervous necrosis, and hirame rhabdoviral disease are 14%, 51%, 25%, and 8% respectively. By investigating the viral infection of broodstock flounder, the infection rate of marine birnavirus （mABV） in hatcheries was identified to be approximately 30%, therefore, it is highly necessary to acquire and keep non-infected broodstock fishes.
