of the two. Some vaccines are specific for cows while the others are designed for calves. Environmental stress and contamination Harsh weather conditions such as low temperatures, rain, heavy snow, wind, and high levels of moisture act as stress factors to young calves and increase the susceptibility of calves to diarrhea [13,71]. Neonatal calves are not able to effectively regulate their... Calf diarrhea is a commonly reported disease in young animals, and still a major cause of productivity and economic loss to cattle producers worldwide. In the report of the 2007 National Animal Health Monitoring System for U.S. dairy, half of the deaths among unweaned calves was attributed to diarrhea. Multiple pathogens are known or postulated to cause or contribute to calf diarrhea development. Other factors including both the environment and management practices influence disease severity or... -

is a classic test of routine postganglionic sudomotor function. We investigated sudomotor function by QSART after summer (July 2012) and winter (January 2013) seasonal acclimation (SA) in the Republic of Korea. QSART with acetylcholine (ACh) iontophoresis were performed to determine directly activated (DIR) and axon reflex-mediated (AXR1, 2) sweating rate. Onset time of axon reflex, activated... a classic test of routine postganglionic sudomotor function. We investigated sudomotor function by QSART after summer (July 2012) and winter (January 2013) seasonal acclimation (SA) in the Republic of Korea. QSART with acetylcholine (ACh) iontophoresis were performed to determine directly activated (DIR) and axon reflex-mediated (AXR1, 2) sweating rate. Onset time of axon reflex, activated sweat gland density (ASGD), activated sweat gland output (ASGO), tympanic and skin temperatures (Tty, Tsk),... -

to Campbell and Madden (1990), and the area under the disease progress curve (AUDPC) was calculated using the Guillen-Sanchez et al. (2003) trapezoid method. Tempera- ture and precipitation weather variables were monitored us- ing a Davis Vantage Pro2 (Davis Instruments, Hayward USA) weather station. Cmm isolation and molecular identification. The phy- tosanitary analysis was performed on all... 1146 and 1510 cm-1 were the distinguishable markers. Chemometric analyses showed the best performance by the implementation of PCA-LDA supervised classification algorithms applied over Raman spectrum data with 100% of performance in metrics of classifiers (sensitivity, specificity, accuracy, negative and positive predictive value) that allowed us to differentiate Cmm from other endophytic bacteria (Bacillus and Pantoea). The unsupervised KMeans algorithm showed good performance (100, 96, 98, 91... -

seed-borne pathogens of rice (Goto, 1964; Kadota, 1996; Shakya et al., 1985). Especially, the occurrence of bacterial leaf blight and bacterial grain rot is becoming more common in Korea as the weather is get- ting hot and humid (Jeong et al., 2003) and these patho- gens can be a threat to rice production in both temperate and tropical rice growing regions due to its high epidemic potential... Burkholderia glumae (bacterial grain rot), Xanthomonas oryzae pv. oryzae (bacterial leaf blight), and Acidovorax avenae subsp. avenae (bacterial brown stripe) are major seedborne pathogens of rice. Based on the 16S and 23S rDNA sequences for A. avenae subsp. avenae and B. glumae, and transposase A gene sequence for X. oryzae pv. oryzae, three sets of primers had been designed to produce 402 bp for B. glumae, 490 bp for X. oryzae, and 290 bp for A. avenae subsp. avenae with the 63°C as an... -

to 36.8% (cv. Bele- nus). The lowest FDK was found in 3 cultivars Ostroga, Boomer and Jenga. Differences in spike and kernel infection in two experi- mental years were the result of contrasting weather condi- tions (Table 4). In 2010, precipitation during heading and flowering was much higher than in 2011. It resulted in higher spike infection in 2010. However, FHB indexes in 2010 and 2011... of trichothecene mycotoxins was analysed. Grain samples originated from plants inoculated with Fusarium culmorum and naturally infected with Fusarium species. The genetic distance between the tested cultivars was determined and data were analysed using multivariate data analysis methods. Genetic dissimilarity of wheat cultivars ranged between 0.06 and 0.78. They were grouped into three distinct groups after cluster analysis of genetic distance. Wheat cultivars differed in resistance to spike and... -

designed eld experiment in 2012 and 2013. Conduciveness of weather conditions at 26 locations in Korea in 2014-2017 was also evaluated using PBcast. The PBcast estimated daily infection risk (IR) of Phytophthora capsici based on weather and soil texture data. In the designed led experiment, four treatments including routine sprays at 7-day intervals (RTN7), forecast-based sprays when IR reached... 고추 역병의 감염위험도 예측모델인 PBcast 포장검증 연구를2012-2013년 동안 수행하였다. 그리고 2014-2017년 동안 우리나라 26개 지점에서 PBcast 모델을 이용하여 발병환경을 평가하였다. PBcast 모델은 기상과 토성자료를 이용하여 Phytophthora capsici의 일일 감염위험도를 추정한다. 시험포장에서 7일 간격으로 살균제를 살포하는 정기방제(RTN7) 처리, 예측된 감염위험도가 200 이상(IR200), 224 이상(IR224)일 때 살포하는 예찰방제 처리, 무방제(CTRL) 처리를 발병주율과 살균제 살포횟수로 비교하였다. 2012년에 감염위험도가... -

period of cloudy, humid (relative humidity; RH above 93%) conditions, and wet weather (Wil- liamson et al., 1995). B. cinerea infections often were not able to detect at the time of harvest, but develop rapidly under moist conditions during storage and shipment (Vrind, 2005). Once infected, petals during wet or humid weather, show masses of silver-gray spores on the whole petals, resulting in... -

their subject con- tent knowledge is delivered and what is assessed. Thus, they use a textbook as a method and assessment of teachers’ teaching, which often becomes inseparable from their everyday routine in the school curriculum. So a textbook becomes an essential part of teaching and assessment. When evaluating science curriculum materials, the administrators and teachers are to examine how... The U.S. science education went through reforms in 1990s and resulted in producing the National Science Education Standards (NSES). A middle school science curriculum, Investigating Earth Systems was newly developed based on the standards. The purpose of this study was to examine how congruent the standards-based science textbook is with the visions of the standards and what characteristics it has. Two instruments were used in analysis: Textbook Questioning Style Assessment Instrument (TQSAI)... -

obtain more than two baseline and intervention data points for Mandy during outside play due to hot weather and an urgent need for intervention. Although changes in levels for problem behavior and engagement were immediate upon intervention and she engaged in the routine without any problem behavior in intervention, more data are required to demonstrate experimental control. In addition, both... This study evaluated the use of the Prevent-Teach-Reinforce (PTR) model, an individualized behavior intervention process, with two teachers and two 4-year-old children in a community preschool classroom. A multiple baseline design across routines was employed to assess teachers’ implementation of the PTR intervention and changes in child behavior. Additional measures associated with the PTR process and outcomes, such as procedural integrity and social validity, were obtained. The results... -

he got, he should have kept working to make money. After his VISA was expired, he decided to stay in South Korea. Of course, he could not even think about any medical service in the severe winter weather, and he became weaker and weaker physically and mentally due to his diseases and extreme work. One day in his first winter in South Korea, he finally collapsed while he had a dinner together... Despite the public health risks to international workers and the urgency to reach them with appropriate public health services and information, few strategies to do so have achieved both effectiveness and sustainability. The present article proposes the identification, recruitment, and activation of informal opinion leaders, a strategy that utilizes interpersonal influence through existing advice-seeking networks among the target population. Coupled with an explanation about recruitment and...
