Practical Life

Everyone knows that phraseological units are the most popular genre of oral folk art, which was formed as a result of life observations of the ancestors. Learning and analyzing Chinese phraseology allow us to better understand the inner world of the Chinese nation. This article reveals and semantically analyzes aspects of the word “head” that are closely related to Chinese culture. The worldview, deep logical thoughts, feelings, superstitions, lifestyle and environment of the Chinese people are described in phraseological expressions in a concise and clear form. This article discusses the semantics and features of Chinese-language phraseological phrases associated with the word “head”. Chinese-language phrases associated with “head” express meanings such as wisdom and ignorance, process of thinking, cunning,sagacity, and planning. Phraseological units in Chinese linguistics are closely related to practical life and determine such features as philosophical and ideological thinking, logical observation. Taking into account the above, the article provides a comparative analysis of phraseological units related to “head” in Chinese and Uzbek languages. The figurative meanings of the word “head” are being revealed, semantic connections and semantic structure of phrases in the sentence are in the process of learning. Chinese phraseological expressions are poorly studied in Uzbek-Chinese studies. We hope that this work will provide practical assistance to our young people who are learning Chinese.

Abstract Background Dividing a surgical procedure into a sequence of identifiable and meaningful steps facilitates intraoperative video data acquisition and storage. These efforts are especially valuable for technically challenging procedures that require intraoperative video analysis, such as transanal total mesorectal excision (TaTME); however, manual video indexing is time-consuming. Thus, in this study, we constructed an annotated video dataset for TaTME with surgical step information and evaluated the performance of a deep learning model in recognizing the surgical steps in TaTME. Methods This was a single-institutional retrospective feasibility study. All TaTME intraoperative videos were divided into frames. Each frame was manually annotated as one of the following major steps: (1) purse-string closure; (2) full thickness transection of the rectal wall; (3) down-to-up dissection; (4) dissection after rendezvous; and (5) purse-string suture for stapled anastomosis. Steps 3 and 4 were each further classified into four sub-steps, specifically, for dissection of the anterior, posterior, right, and left planes. A convolutional neural network-based deep learning model, Xception, was utilized for the surgical step classification task. Results Our dataset containing 50 TaTME videos was randomly divided into two subsets for training and testing with 40 and 10 videos, respectively. The overall accuracy obtained for all classification steps was 93.2%. By contrast, when sub-step classification was included in the performance analysis, a mean accuracy (± standard deviation) of 78% (± 5%), with a maximum accuracy of 85%, was obtained. Conclusions To the best of our knowledge, this is the first study based on automatic surgical step classification for TaTME. Our deep learning model self-learned and recognized the classification steps in TaTME videos with high accuracy after training. Thus, our model can be applied to a system for intraoperative guidance or for postoperative video indexing and analysis in TaTME procedures.

In this paper, we study mathematical model of ecology with a tritrophic food chain composed of a classical Lotka-Volterra functional response for prey and predator, and a Holling type-III functional response for predator and super predator. There are two equilibrium points of the system. In the parameter space, there are passages from instability to stability, which are called Hopf bifurcation points. For the first equilibrium point, it is possible to find bifurcation points analytically and to prove that the system has periodic solutions around these points. Furthermore the dynamical behaviors of this model are investigated. Models for biologically reasonable parameter values, exhibits stable, unstable periodic and limit cycles. The dynamical behavior is found to be very sensitive to parameter values as well as the parameters of the practical life. Computer simulations are carried out to explain the analytical findings.
