Methods: 92 cases of pediatric patients admitted to our hospital from June to November 2021 were selected for this study. According to the time of admission, 46 cases were divided into the control group (admitted from June to August 2021) and the combined group (admitted from September to November 2021). Both groups of children were given routine care. The former was given routine intervention while the latter was given multiple forms of psychological intervention on the basis of the former. The nursing compliance, SCARED (anxiety disorder) score, DSRSC (depression disorder) score and parents satisfaction with the nursing work were compared between the two groups. Results: compared the total score of nursing compliance between the two groups, the score of the control group (40.3±3.5) was lower than that of the combined group (55.2±2.1). Compared the SCARED and DSRSC scores of the two groups of children after nursing, the two scores of the control group were all higher than the two scores of the combined group;Compared with the total satisfaction of parents in the two groups, the control group was 76.09%(35/46) < the combined group was 91.30%(42/46). there were differences in the above three measurement indexes and one counting index between the two groups (p < 0.05). Conclusion: the adoption of various forms of psychological intervention for pediatric children can improve the childrens bad mood and mentality, and guide the gradual formation of their correct behavior, so as to improve the treatment coordination and nursing compliance, and win higher satisfaction from the parents of the children.展开更多

According to the situation of 160 senile cataract patients treated in our hospital in recent years, this research method was randomly distributed and divided into the control group and the observation group. The control group adopted the traditional nursing method, and the observation group applied various forms of health education on the basis of the above, and analyzed the nursing effect of the control group and the control group. The laboratory observation results compared the health awareness and treatment satisfaction of the two groups of patients, which were significantly higher than those of the control group (P<0.05) and significantly lower than those of the control group (P<0.05). Conclusion: the multi-level health education model for senile cataract patients can significantly improve the patients' health awareness, improve the satisfaction of medical services and reduce the incidence of complications.展开更多

The mathematical tool that made it possible to explore and analyze this equation is the Bogning-Djeumen Tchaho-Kofané method extended to the new implicit Bogning' functions. The analytical form of the solutions chosen in this manuscript is particular in the sense that it contains within its bosom, a package of solitary waves made up of three solitons, especially, the bright type soliton, the hybrid soliton and the dark type soliton which we estimate capable in their interactions of generating new hybrid or multi-form solitons. Existence conditions of the obtained solitons have been determined. It emerges that, these existence conditions of the chosen ansatz could open the way to other new varieties of fifth-order KdV equations including to which it will be one of the solutions. Some of the obtained solitons are exact solutions. Intense numerical simulations highlighted numerical stability and confirmed the hybrid character of the obtained solutions. These results will help to model new nonlinear wave phenomena, in plasma media and in fluid dynamics, especially, on the shallow water surface.展开更多

The model considered for this purpose is the modified KdV (Korteweg-de Vries) equation. A peculiarity of the obtained solutions is that they form packages constituted by combinations of waves belonging to the two main families of well-known bright and dark solitary waves. This putting together creates competitions between the different components of the considered packages which, following the values assigned to the parameters of the considered system and in relation to those of the wave parameters, generate hybrid or multi-form structures. The direct method of resolution which made possible the obtained results is that of Bogning-Djeumen Tchaho-Kofane extended to the new implicit Bogning functions. The existence conditions of some solutions are obtained. The numerical simulations carried out with a view to testing the observable and applicable characters of the obtained solutions revealed their stabilities over a relatively long time, and at the same time, confirmed the recommended theoretical forecasts. We are convinced that the solutions proposed as part of this work will make it possible to detect, understand and explain some physical phenomena linked to fluid molecular interactions, former or new, which constantly occur on the fluid surfaces, mainly at the shallow water surface.展开更多

The problem is NP-hard when f（x） has degree 3 or higher. Denote by fmin （resp. fmax） the minimum （resp. maximum） value of f（x） on S^n-1. First, when f（x） is an even form of degree 2d, we study the standard sum of squares （SOS） relaxation for finding a lower bound of the minimum .fmin ：max γ s.t.f（x）-γ.｜｜x｜｜2^2d is SOS.Let fos be be the above optimal value. Then we show that for all n ≥ 2d,Here, the constant C（d） is independent of n. Second, when f（x） is a multi-form and ^-1 becomes a muilti-unit sphere, we generalize the above SOS relaxation and prove a similar bound. Third, when f（x） is sparse, we prove an improved bound depending on its sparsity pattern; when f（x） is odd, we formulate the problem equivalently as minimizing a certain even form, and prove a similar bound. Last, for minimizing f（x） over a hypersurface H（g） = {x E lRn： g（x） = 1} defined by a positive definite form g（x）, we generalize the above SOS relaxation and prove a similar bound.展开更多
