Objective To study the current situation of migrant children' s social adaptation and ex?plore its influencing factors. Methods The study population was 1547 children aged 10?16 years recruited from Shijiazhuang city. Social adaptation was collected through social adaptation questionnaire,whereas self?control was measured by children' s self?control investigating questionnaire. The data were statistically ana?lyzed with the ANOVA and stepwise regression analysis. Results ①There was no significant difference on social adaptation scores between migrant children and urban children (3.71±0.65,3.70±0.69, P>0.05). ②Among migrant children,girls scored significantly higher than boys(3.80±0.59,3.63±0.69, P<0.01). And as the grade of the migrant children increased,the social adaptation scores decreased (3.82±0.68,3.72±0.64, 3.58±0.60, P<0.01). ③The poor control system had a significantly negative prediction on migrant children' s social adaptation ( β=-0.299, P<0.01),whereas the good self?control system had a significantly positive prediction on migrant children' s social adaptation ( β=0.243, P<0.01) . Both parent?child relationship and peer relationship significantly positively predicted migrant children ' s social adaptation ( β=0. 179, β=0.092, P<0.01) . There was no significant correlation between the proportion of the migrant children in the classes and migrant children's social adaptation (P>0.05). Conclusion There is no significant difference on social adaptation between migrant children and urban children. Children' s self?control,parent?child rela?tionship and peer relationship have significant influence on social adaptation of migrant children .

Objective To learn how the process of self-regulatory fatigue (SRF) mediates the effect of leadership styles on job satisfaction of young workers.Methods 723 young workers recruited from a business enterprise were required to response to questionnaire survey, including leader behavior description, self-regulatory fatigue and job satisfaction questionnaire.Results All young workers' job satisfaction was 3.78±0.69,31 years old and above were higher than 30 years old and under(t=-3.246, P＜0.01) ,and there was no significant difference in gender and education.Job satisfaction was significantly positively correlated with leadership style (r initiating structure =0.210, r ideration =0.272), and was significantly negatively correlated with self-regulatory fatigue (r=-0.333).Two dimensions of leadership styles,initiating structure (β=0.227, t=2.659, P＜0.01) and consideration (β=0.270, t=5.035, P＜0.01), had the predicted effects of job satisfaction (R 2 =0.098).Consideration dimension of leadership style had more influence on job satisfaction at the high level of self-regulatory fatigue (β=0.266, t=4.929, P＜0.01);the effect of initiating structure dimention on job satisfaction was influenced by gender (t=-5.154, P＜0.01);self-regulatory fatigue was mediator between leadership styles and job satisfaction, and the consideration dimension of leadership style had more mediation effect on job satisfaction than that of initiating structure dimention of leadership style (mediationconsideration=0.317,mediationinitiating structure=0.268).Conclusion Two dimensions of leadership style can affect job satisfaction, and are mediated by self-regulatory fatigue.The intervention of self-regulatory fatigue can help to improve the job satisfaction of young workers.

Objective:To develop a set of algorithms that could predict the precise size of acetabular cup preoperatively by the deep learning neural network technology.Methods:Retrospective analysis was performed on 30 patients with femoral head necrosis from April 2019 to April 2020, including 15 males and 15 females. At the age of (54.8±10.5) years (range 33-72 years). Thirteen hips on the left and seventeen hips on the right, who underwent primary unilateral THA. Based on the manually segmented hip joint CT database, a deep learning convolutional neural network was trained to realize automatic segmentation. A customized algorithm was created to fit the surface of the acetabulum. By the application of another deep learning convolutional neural network, the identification of anatomical points of the pelvis and correction of the pelvic position were realized. So that the placement of the acetabulum cup could be done. DOC (dice overlap coefficients) as well as the average error parameter were adopted to evaluate the accuracy of the above steps. The novel algorithm and Orthoview software were retrospectively used to template the acetabular cup separately. The results of both groups were compared with the actual size and the coincidence rate was calculated to evaluate the accuracy of the novel algorithm. To verify this algorithm, the conformance rate was calculated respectively.Results:Compared with other classical segmentation networks, the G-NET network can segment the pelvic with femoral head necrosis more accurately (DOC 92.51%± 6.70%). It also has better robustness. The average error of the point recognition network is 0.87 pixels. Among the 30 patients, the AI-based algorithm group had a complete coincidence rate of 96.7% and the Orthoview group had a complete coincidence rate of 73.3%. The difference was statistically significant ( χ2=6.405, P=0.011). Conclusion:The artificial intelligence-based algorithm can segment the CT image series and identify the feature points of the patient's hip accurately. Compared with the conventional 2D preoperative planning method, the AI-based algorithm is relatively more accurate. This artificial intelligence-based 3D preoperative software has promising prospect to makeaccurate surgical plan efficiently.
