不同雾化吸入方式在小儿哮喘临床治疗中的应用对比

目的:探究不同雾化吸入方式对小儿哮喘治疗的应用疗效。方法:选取90例小儿哮喘患儿进行临床研究,随机分为三组:甲组、乙组、丙组,甲组接受空气压缩泵式雾化吸入法,乙组接受氧气压缩泵雾化吸入法,丙组接受超声雾化吸入法,所用药物均为布地奈德和博尼康尼,观察三组患者的临床疗效并比对效果。结果:三组雾化吸入方式的临床疗效具有统计学差异(P>0.05)。结论:空气压缩泵式雾化吸入法的临床效果明显好于其他两种方法,并且雾化的药物不同,疗效也具有显著差别,选择合适的药物和空气压缩泵式雾化吸入法将提高临床疗效。

心理及康复护理干预在老年脑血栓患者中的应用效果

从对老年脑血栓患者的调查研究活动中探究心理及康复护理干预的护理应用效果。方法:调查研究从我院选取50例符合活动要求的老年脑血栓患者作为研究观察群体,患者接受治疗与护理的时间数据均为2019年2月至2020年6月。随后,使用电脑来对患者群体进行计量分组,共计分为对照研究组与试验研究组,组内患者的人数均等,且均为25人。其中前者对应脑血栓干预护理,而后者则对应心理及康复护理干预方案,最终将两组患者在护理中的表现以及评分量表数据进行对比,得出不同护理方案所取得的实践差异。结果:两种不同护理方案的分别得出不同的结果,从护理效果来看,试验研究组患者的总体护理有效率高于对照研究组患者,而从FMA以及Bl量表的数据来看,试验研究组患者护理前后的量表评分差异具有更加明显的优化,而从患者对不同护理干预的满意度来看,试验研究组老年患者对护理干预的满意度更高。结论:在脑血栓老年患者的护理过程中,运用心理及康复护理干预方式能够取得较为良好的干预效果,并且对患者生活状态以及肢体功能都有着良好的改善作用。

Application of extension neural network to safety status pattern recognition of coalmines

In order to accurately and quickly identify the safety status pattern of coalmines,a new safety status pattern recognition method based on the extension neural network (ENN) was proposed,and the design of structure of network,the rationale of recognition algorithm and the performance of proposed method were discussed in detail.The safety status pattern recognition problem of coalmines can be regard as a classification problem whose features are defined in a range,so using the ENN is most appropriate for this problem.The ENN-based recognition method can use a novel extension distance to measure the similarity between the object to be recognized and the class centers.To demonstrate the effectiveness of the proposed method,a real-world application on the geological safety status pattern recognition of coalmines was tested.Comparative experiments with existing method and other traditional ANN-based methods were conducted.The experimental results show that the proposed ENN-based recognition method can identify the safety status pattern of coalmines accurately with shorter learning time and simpler structure.The experimental results also confirm that the proposed method has a better performance in recognition accuracy,generalization ability and fault-tolerant ability,which are very useful in recognizing the safety status pattern in the process of coal production.

Service Function Chain in Small Satellite-Based Software Defined Satellite Networks

Software Defined Satellite Networks(SDSN) are proposed to solve the problems in traditional satellite networks, such as time-consuming configuration and inflexible traffic scheduling. The emerging application of small satellite and research of SDSN make it possible for satellite networks to provide flexible network services. Service Function Chain(SFC) can satisfy this need. In this paper, we are motivated to investigate applying SFC in the small satellite-based SDSN for service delivery. We introduce the structure of the multi-layer constellation-based SDSN. Then, we describe two deployment patterns of SFC in SDSN, the Multi-Domain(MD) pattern and the Satellite Formation(SF) pattern. We propose two algorithms, SFP-MD, and SFP-SF, to calculate the Service Function Path(SFP). We implement the algorithms and conduct contrast experiments in our prototype. Finally, we summarize the applicable conditions of two deployment patterns according to the experimental results in terms of hops, delay, and packet loss rate.
