Helmet Wearing Recognition of Construction Workers Using Convolutional Neural Network

One of the most effective ways to prevent construction workers from suffering a head injury is to wear a safety helmet.The use of a computer vision method to detect whether or not construction workers are wearing helmets can improve external construction worker supervision, reducing the number of head injury accidents.A helmet-wearing recognition method based on head recognition is proposed using cnn (convolutional neural network).The area of the head of constructors can be accurately located using crossvalidation of facial feature recognition and head recognition, which solves the problem of determining constructor head position under complex posture.The i-yolov3 target detection network is used to detect helmet wear, and the relative position relationship between the helmet and the human body is determined.The findings show that the helmet wearing identification system can be successfully applied to helmet wearing identification work in a complex environment construction site, and it offers a new research perspective and technical method for construction industry information-based safety monitoring.

Research on the Evaluation and Optimization of Innovation Ability of Private Enterprises Based on DEA Model

As private businesses are an integral part of china’s market economy, it is essential to foster their expansion in a positive manner.Even though some private enterprises have made significant strides in their ability to innovate independently, the majority of them have not yet established an effective endogenous mechanism of independent innovation, and their independent innovation capability and level are insufficient to meet the requirements of economic and social development in the new era.Therefore, it is essential to evaluate the innovation capacity of private businesses.Therefore, the first section of this paper examines the research on measuring enterprise productivity.Second, this paper employs a combination of endogenous dynamics to develop an endogenous dynamics mechanism that encourages innovation in private companies.In addition to employing the dea model, this paper proposes an evaluation optimization mechanism for assessing the innovation capability of private enterprises in a chinese province from 2015 to 2021.It concludes that the innovation capability of private enterprises in this province is generally low and that factors such as the number of technical employees, the r&amp;d investment funds of private enterprises, and the number of granted patents have a significant impact.

The Asymmetric Utility of Cultural Distance in International Business based on the Cultural Bias

As an index to measure the cultural differences between countries, culture distance (cd) is a widely used construct in international business and postulated to be symmetric in previous studies.However, cd symmetry across different countries is been demonstrated to result in the national cd paradox.A new asymmetry index utility cultural distance (ucd) is proposed to replace the previous one in this study.The cultural utility function is applied to calculate the ucd for a particular country, where the cultural bias could cause the asymmetric change of cultural score.The index is verified to be a significant variable in the regression analysis of china’s outward foreign directing investment to 17 other countries in 15 years.The ucd demonstrated in this paper corrects the fallacious symmetry assumption on cultural distance and can maintain a consistent and effective conclusion on cultural differences in international business studies.

The Protection and Restoration of Ancient Buildings in Guanzhong Traditional Villages Based on the Improved Priority Algorithm

Architecture is closely related to human development.Different architectural shapes and texture structures reflect the changes of society and the level of social development.They are not only important materials for studying history but also carry the profound significance of human history.However, due to chemical effects, the acid, alkali, salt, and corrosive solvents are applied and produced in the process of industrial production, as well as the corrosive media contained in the atmosphere, groundwater, surface water, and soil will corrode the ancient buildings.The whole picture of many ancient buildings cannot be completely preserved, let alone used as research materials to deeply explore history and humanities.With the development of computer science and technology, we hope to protect and repair traditional ancient buildings through modern technology, which not only respects the long history of the chinese nation but also helps us better study history through ancient buildings.This paper takes the ancient buildings of traditional villages in guanzhong, shanxi province as an example, optimizes them on the basis of predecessors, and explores the protection and restoration of ancient buildings based on the improved priority algorithm.The results show that the proposed algorithm performs better in the protection and restoration model of ancient buildings than the traditional algorithm.

Gluconeogenesis Alteration and p53-SIRT6-Fox01 Signaling Adaptive Regulation in Sheep from Different Grazing Periods

The decline in sheep health and meat quality caused by seasonal nutritional deficiencies has always been an important problem in the production of naturally grazing sheep.Glucose metabolism is crucial in ruminants for adequate cell function and maintenance of the body tissues and systems.However, whether glucose metabolism, especially gluconeogenesis, is affected by seasonal grazing conditions has not been fully uncovered.Thus, twelve sheep from two seasons (dry and green grass periods) in natural grazing areas of inner mongolia, china, were selected for this study.Their serum glucose, insulin, pc, and pepck levels and volatile fatty acid (gluconeogenesis material) concentrations in rumen fluid were analyzed.The expression of key enzymes including pc, pepck, glut2, and g6p of gluconeogenesis and their regulators insr, pi3k/akt and p53-sirt6-fox01 in the liver was detected by real-time pcr and western blotting.The results revealed significant variances in gluconeogenesis and its indicators and showed p53-sirt6-fox01 as having potential regulation in different grazing periods.This study offers new insights into the mechanism of gluconeogenesis and adaptive regulation between dry grass period and green grass period and also provides a reference for maintaining the health of sheep and meat quality despite seasonal nutritional deficiencies.

Fibroblast Growth Factor 3 Is Associated with Tongue Squamous Cell Carcinoma: A Controlled Study

To explore the effects of fibroblast growth factor 3 (fgf3) on the proliferation, cell cycle, and apoptosis of the tongue squamous cell carcinoma scc-9 cell line (scc-9).Methods.We measured the proliferation of scc-9 cells in a control group, an fgf3 intervention group, and a fibroblast growth factor (fgfr) inhibitor intervention group in cholecystokinin octapeptide (cck-8) experiments.We studied effects of fgf3 on the cell cycle and apoptosis of tongue cancer cells using flow cytometry.We further explored the irs1/pi3k/akt signaling pathway by measuring bcl-2 and bcl-2 associated x-protein (bax) m rna and protein levels with rt-pcr and western blot, respectively.Results.Results from the cck-8 experiment showed that survival rates of cells in the control group, fgf3 intervention group, and fgfr inhibitor intervention group were 100.000 % ± 4.026 % , 136.330 % ± 9.779 %, and 83.199 % ± 4.954 %, respectively; survival rates of scc-9 cells in all three groups were statistically significant ( p &lt; 0.05 ).Compared with that in the control group, the ratio of cells in g0/g1 phase in the fgfr inhibitor intervention group was higher ( p &lt; 0.05 ) and that in g2/m phase was lower, while the fgf3 intervention group showed opposite results ( p &lt; 0.05 ).The apoptosis rate of tongue cancer cells differed significantly between the fgfr inhibitor intervention and the control groups ( p &lt; 0.05 ).The m rna and protein expression levels of irs1, pi3k, and bcl-2 were all increased in the fgf3 intervention group ( p &lt; 0.05 ), while bax m rna and protein expression levels were decreased ( p &lt; 0.05 ).The m rna expression levels of protein kinase b (akt) showed no differences between groups.The p-akt protein was overexpressed, while the total amount of akt protein remained stable ( p &lt; 0.05 ).Conclusion.Fgf3 contributes to the proliferation of scc-9 cells by increasing the proportion of cells in g2/m phase.Therefore, appropriately timed inhibition of fgf3 can potentially promote tumor apoptosis through the irs1/pi3k/akt signaling pathway.Our results demonstrate the role of fgf3 in the tumor microenvironment in tongue squamous cell carcinoma scc-9 cells and suggest new therapeutic targets.
