BACKGROUND To evaluate the effect on problem behaviors of a universal school-based prevention curriculum of third grade students. METHODS Six regular classes in 1 elementary school were randomly assigned to an intervention (n = 208) or control (n = 209) group. A 13-session program was offered to students in the intervention group. The Achenbach Child(More)
This article introduces a method of optimizing design of ASSEL roller profile. It obtains the feed angle and toe angle for all rolling gauges with genetic artificial neural network (GANN), and to optimize weight coefficient and network structure by training of weight value of genetic neural network. The model was tested on the imported ASSEL mill. The(More)
Heat stress-induced reduction in feed intake is an annoyance of the poultry industry. Feed intake is regulated by complex mechanisms in which brain-gut neuropeptides are involved, but the changes in such neuropeptides in broiler chickens during heat exposure remain unclear. In this study, we investigated the effects of acute heat stress (35°C, 6 h, and 65%(More)
Chinese school-aged children in urban areas of Beijing, China were surveyed in 1985, 1993, and 2003 consecutively regarding their behavioral problems. The instrument of the Rutter Scale for children’s behavior problems was used, so that the obtained data can be compared over the time. The results revealed that total behavioral problems increased remarkably(More)
SARS is an acute infectious disease and can cause a large amount of death. Up until now we have not known it well. With the experimental results of micronutrients of 30 SARS patients and 30 non-SARS patients, using rough set theory we induce some classification rules. Attribute reduction results show that micronutrients Fe, Ca, K and Na are necessary and(More)
OBJECTIVES To delineate clinical and pathological features and determine the prognostic factors of primary intraosseous squamous cell carcinoma (PIOSCC). MATERIALS AND METHODS Patients diagnosed with PIOSCC, attending the department of oral and maxillofacial surgery, Nanjing stomatological hospital between 2005 and 2015, were identified and(More)
According to the retrieval algorithm of adjusting automatic the weight of multi-features, and which the algorithm exist some deficiency, like that have not the study mechanism and so on. The paper analyzed and studied in the BP neural network in the learning process, and has realized the image retrieval method based on the BP neural network relevance(More)
