Research on the Guidance of Youth Labor Education Based on the "Combination of Education and Production Labor" Program Based on the Deep Learning Model.

At present, there is a lack of research on Marx's idea of "combining education and productive labor" and its guiding significance for youth labor education, and no effective teaching model has been formed. In response to this problem, this study proposes a semi-supervised deep learning model based on u-wordMixup (SD-uwM). When there is a shortage of labeled samples, semi-supervised learning uses a large number of unlabeled samples to solve the problem of labeling bottlenecks. However, since the unlabeled samples and labeled samples come from different fields, there may be quality problems in the unlabeled samples, which makes the generalization ability of the model worse., resulting in a decrease in classification accuracy. The model uses the u-wordMixup method to perform data augmentation on unlabeled samples. Under the constraints of supervised cross-entropy and unsupervised consistency loss, it can improve the quality of unlabeled samples and reduce overfitting. The comparative experimental results on the AGNews, THUCNews, and 20Newsgroups data sets show that the proposed method can improve the generalization ability of the model and also effectively improve the time performance. The study found that the SD-uwM model uses the u-wordMixup method to enhance the unlabeled samples and combines the idea of the Mean Teacher model, which can significantly improve the text classification performance. The SD-uwM model can improve the generalization ability and time performance of the model, respectively, 86.4 ± 1.3 and 90.5 ± 1.3. Therefore, the use of SD-uwM in Marx's program is of great practical significance for the guidance process of youth labor education.

Application-aware deadline constraint job scheduling mechanism on large-scale computational grid.

Recently, computational Grids have proven to be a good solution for processing large-scale, computation intensive problems. However, the heterogeneity, dynamics of resources and diversity of applications requirements have always been important factors affecting their performance. In response to these challenges, this work first builds a Grid job scheduling architecture that can dynamically monitor Grid computing center resources and make corresponding scheduling decisions. Second, a Grid job model is proposed to describe the application requirements. Third, this paper studies the characteristics of commercial interconnection networks used in Grids and forecast job transmission time. Fourth, this paper proposes an application-aware job scheduling mechanism (AJSM) that includes periodic scheduling flow and a heuristic application-aware deadline constraint job scheduling algorithm. The rigorous performance evaluation results clearly demonstrate that the proposed application-aware job scheduling mechanism can successful schedule more Grid jobs than the existing algorithms. For successful scheduled jobs, our proposed AJSM method is the best algorithm for job average processing time and makespan.

[Langerhans cell histiocytosis: a case report].

A case of Langerhans cell histiocytosis of the mandible was reported. A 34-year-old woman presented with pain for one year on the gingival of the low left jaw, and together with pyorrhea in the past 2 months. The histopathology and immunohistochemical examination confirmed the diagnosis of Langerhans cell histiocytosis.

[Treatment of cleft palate with secretory otitis media].

OBJECTIVE: To gain a clear idea of the function of middle ear and hearing in cleft palate with secretory otitis media after pressure equalization tube insertion. METHODS: 53 cleft palate cases with secretory otitis media including 62 ears were divided into treatment and control groups. They were examined by tympanogram and hearing threshold. RESULTS: Hearing threshold in treatment group after PE tube insertion respectively was 23.3 dB and 23.4 dB in the near future and at a specified future date. It was normal. But there were still 64% tympanogram B and C. CONCLUSIONS: PE tube insertion could solve hearing problem, but could not improve the function of middle ear.

[A preliminary study of the two models treated by presurgical orthopedics compared with early soft palate adhesion method].

OBJECTIVE: To compare results of the growth and development of the upper dental arch and the velopharyngeal closure of the cleft patients treated by two methods. METHODS: The dental cast of patient and X-ray films were measured and the statistical medical records were analyzed. RESULTS: The transverse distance of upper dental arch was found to be wider in group A than in group B. The anterior-posterior distance of the dental arch in bilateral cleft group was shorter in group A than in group B. The difference of the two groups were gradually lessened as age increases. Bony bridge in alveolar gap was 63% and 83.3% in unilateral and bilateral cleft group respectively. 15% of cases in group A and 35.2% in group B needed pharyngeal flap. CONCLUSIONS: The stable upper dental arch in group A can opposes the pressure from the lip muscles, this maintains the width of the arch. But A-P distance of upper dental arch in BCLP in group A should be followed up after the age of 9 years. Pharyngeal flap is needed less in group A than in group B.
