Influence of initial check, information exchange, final accuracy check, reaction information nursing on the psychology of elderly with lung cancer

BACKGROUND As one of the fatal diseases with high incidence,lung cancer has seriously endangered public health and safety.Elderly patients usually have poor self-care and are more likely to show a series of psychological problems.AIM To investigate the effectiveness of the initial check,information exchange,final accuracy check,reaction(IIFAR)information care model on the mental health status of elderly patients with lung cancer.METHODS This study is a single-centre study.We randomly recruited 60 elderly patients with lung cancer who attended our hospital from January 2021 to January 2022.These elderly patients with lung cancer were randomly divided into two groups,with the control group taking the conventional propaganda and education and the observation group taking the IIFAR information care model based on the conventional care protocol.The differences in psychological distress,anxiety and depression,life quality,fatigue,and the locus of control in psychology were compared between these two groups,and the causes of psychological distress were analyzed.RESULTS After the intervention,Distress Thermometer,Hospital Anxiety and Depression Scale(HADS)for anxiety and the HADS for depression,Revised Piper’s Fatigue Scale,and Chance Health Locus of Control scores were lower in the observation group compared to the pre-intervention period in the same group and were significantly lower in the observation group compared to those of the control group(P<0.05).After the intervention,Quality of Life Questionnaire Core 30(QLQ-C30),Internal Health Locus of Control,and Powerful Others Health Locus of Control scores were significantly higher in the observation and the control groups compared to the pre-intervention period in their same group,and QLQ-C30 scores were significantly higher in the observation group compared to those of the control group(P<0.05).CONCLUSION The IIFAR information care model can help elderly patients with lung cancer by reducing their anxiety and depression,psychological distress,and fatigue,improving their tendencies on the locus of control in psychology,and enhancing their life qualities.

Effect of annealing temperature on microstructure and mechanical properties of Mg-Zn-Zr-Nd alloy with large final rolling deformation

In this study,the Mg-3Zn-0.5Zr-χNd(χ=0,0.6)alloys were subjected to final rolling treatment with large deformation of 50%.The impact of annealing temperatures on the microstructure and mechanical properties was investigated.The rolled Mg-3Zn-0.5Zr-0.6Nd alloy exhibited an ultimate tensile strength of 386 MPa,a yield strength of 361 MPa,and an elongation of 7.1%.Annealing at different temperatures resulted in reduced strength and obviously increased elongation for both alloys.Optimal mechanical properties for the Mg-3Zn-0.5Zr-0.6Nd alloy were achieved after annealing at 200℃,with an ultimate tensile strength of 287 MPa,a yield strength of 235 MPa,and an elongation of 26.1%.The numerous deformed microstructures,twins,and precipitated phases in the rolled alloy could impede the deformation at room temperature and increase the work hardening rate.After annealing,a decrease in the work hardening effect and an increase in the dynamic recovery effect were obtained due to the formation of fine equiaxed grains,and the increased volume fraction of precipitated phases,which significantly improved the elongation of the alloy.Additionally,the addition of Nd element could enhance the annealing recrystallization rate,reduce the Schmid factor difference between basal and prismatic slip systems,facilitate multi-system slip initiation and improve the alloy plasticity.

Teachers’Perception for Evaluation of the Primary School Students With Final Grade

The most difficult and delicate part of the learning process is assessment.Assessment is difficult because during his/her accomplishment the teacher has to consider not only the acquisition of knowledge from students,but also the overall degree of development of their competencies.It is delicate,because through assessment we can influence the emotional side of students and their“willingness”to learn.Despite these facts,teachers need to evaluate students during the learning process.The purpose of the research is to find out what is the perception of teachers about the level of evaluation of students with final grade.The overall results showed that 89%of teachers agree,9%of them have a neutral attitude,and 2%do not agree that the evaluation of students with a final grade is done taking into account many aspects and using many methods,the overall average of the results,M=4.36.Based on the empirical results,it was found that teachers who have completed assessment training have a more positive approach to student assessment,as the average score is higher than teachers who have not completed assessment training.From the qualitative results it was understood that the Teachers did not encounter any difficulties during the assessment of the students.

A Review on Determinants Affecting Commercialization of Academic Institution Final Year Projects

Final year project is an important training and assessment component incorporated in many courses of academic institution.The ability to translate ideas,research,and creativity into actual products,services,or businesses shows how successful and impactful people or institutions can be in the wider economy.However,in most of the cases,the outcomes of the final year project usually remain as academic discussion without maximizing their potential to be converted into a commercialized product or services.In this review,theory and applications are discussed to understand how entrepreneurial skills and networking abilities,components of individuals’human capital can impact the commercialisation of final year projects.Furthermore,determinants affecting commercialization of final year projects will also be explored namely:entrepreneurial skills,networking ability,access to resources,institutional support as well as creativity and innovation.

Revisiting Akaike’s Final Prediction Error and the Generalized Cross Validation Criteria in Regression from the Same Perspective: From Least Squares to Ridge Regression and Smoothing Splines

In regression, despite being both aimed at estimating the Mean Squared Prediction Error (MSPE), Akaike’s Final Prediction Error (FPE) and the Generalized Cross Validation (GCV) selection criteria are usually derived from two quite different perspectives. Here, settling on the most commonly accepted definition of the MSPE as the expectation of the squared prediction error loss, we provide theoretical expressions for it, valid for any linear model (LM) fitter, be it under random or non random designs. Specializing these MSPE expressions for each of them, we are able to derive closed formulas of the MSPE for some of the most popular LM fitters: Ordinary Least Squares (OLS), with or without a full column rank design matrix;Ordinary and Generalized Ridge regression, the latter embedding smoothing splines fitting. For each of these LM fitters, we then deduce a computable estimate of the MSPE which turns out to coincide with Akaike’s FPE. Using a slight variation, we similarly get a class of MSPE estimates coinciding with the classical GCV formula for those same LM fitters.

硅酸钠改善碱激发材料力学性能与凝结机理分析

为了进一步增强碱激发材料的力学性能,掌握碱激发材料的凝结规律,通过掺入不同种类与掺量硅酸钠进行增硅改性,增强矿渣碱激发材料反应活性,定期观测试件的力学性能并分析凝结规律,同时结合微观分析手段深入剖析硅酸钠的增硅增强机理。结果表明,固态与液态硅酸钠均能够显著提高试件的抗压强度,明显缩短初凝与终凝时间。随固态硅酸钠掺量的提升,试件抗压强度呈先上升后下降趋势,固态硅酸钠在试件内大量结晶是导致抗压强度下降的主要原因。随液态硅酸钠掺量的提升,试件抗压强度呈先显著上升后趋于平稳的趋势,这说明其增强作用具有最大限值,液态硅酸钠的激发效果明显优于固态。

1960-2020年黄河流域农业热量资源时空演变特征

[目的]气候变暖将改变农业热量资源的时空分布,对黄河流域农业热量指标进行分析,可为区域合理利用农业气候资源提供依据。[方法]基于1960-2020年黄河流域89个气象站点逐日气象资料,运用线性趋势估计和Mann-Kendall突变检验等方法分析了黄河流域年平均气温,≥0℃和≥10℃的初终日、持续日数和有效积温的时空变化特征及其影响因素。[结果]近61 a黄河流域平均气温、≥0℃和≥10℃有效积温分别以0.29℃·(10 a)^(-1)、70.23℃·d·(10 a)^(-1)和34.50℃·d·(10 a)^(-1)的倾向率呈上升趋势,≥0℃和≥10℃持续日数呈增加趋势,倾向率分别为3.33 d·(10 a)^(-1)和2.78 d·(10 a)^(-1)。≥0℃和≥10℃初日呈提前趋势,倾向率分别为—2.16 d·(10 a)^(-1)和—2.14 d·(10 a)^(-1),≥0℃和≥10℃终日呈延迟趋势,倾向率分别为1.16 d·(10 a)^(-1)和0.63 d·(10 a)^(-1),≥0℃和≥10℃初日提前的幅度大于终日推迟的幅度,≥0℃初终日和持续日数变化幅度大于≥10℃相应指标变化幅度。近61 a黄河流域年平均气温、≥0℃和≥10℃有效积温分别于1996、2003和1997年发生突变。黄河流域上、中、下游地区各热量指标变化趋势与流域整体变化一致,上游地区变化幅度相对较大。从空间分布来看,由上游、中游到下游地区年平均气温逐渐增加,≥0℃和≥10℃有效积温逐渐增加,初日逐渐提前,终日逐渐推迟,持续日数逐渐延长。[结论]黄河流域农业热量资源呈增加趋势,热量指标主要受海拔高度和年平均气温影响。西太平洋副高强度指数、太平洋副高强度指数和东大西洋遥相关型指数是影响近61 a黄河流域农业热量指标变化的主要大气环流因子。

句末助词“的”的功能分类及语义演变

本文主张普通话的句末助词“的”应分为“过去焦点化”和“确认语气”两个功能。该词的功能分类标准不宜是句子焦点域的宽窄,而应是“的”自身的语法作用:可否隐去,可否用于疑问句,对所述事件及焦点成分的语法限制,对整句语篇功能的影响等。本文证明,窄焦点句“他是昨天到北京的”和宽焦点句“(这事儿)是警察把他抓起来的”中的“的”都是结构助词,而宽焦点句“主任明天会来单位的”中的“的”是语气助词。我们将“的”的语义演变路径构拟为“名词化标记→过去焦点化→确认语气”,并探讨了普通话句末“的”与“了_(2)”的异同点,还比较了方言里“的”类词和“有”类词的用法。

论时态与限定范畴——以监利赣语的句末词“在”为例

湖北监利赣语的句末词“在”只能出现在表示静态持续意义的句子中。这些句子必须是根句或是带有时间状语的关系子句,不能出现在非限定子句中。句末“在”对谓语动词有两方面的语义要求。首先,谓语动词必须是自主动词;其次,谓语表达的情景体必须是静态的、持续的、无终结点的。监利赣语的句末“在”既不是句末语气助词,也不是句末体貌助词,它是限定范畴的标记,具有说话者属性,可以通过引入说话者来锚定说话时间,帮助句子获得时间解读。

闽东方言变韵的机制与方向

从闽东方言的闽清县坂东镇新近出现的变韵现象出发,通过声学分析发现,变韵在不同声调条件下有不同的时长结构。闽东南北两片代表性方言(福州、连江、宁德、周宁)松紧复合韵母的声学分析显示,声调对元音时长的影响在先,继而元音时长的改变诱发其响度增减。因此,也可以说,声调影响元音时长,元音时长与相对响度相关,三者共同构成闽东方言变韵的机制。最后,结合闽东方言韵母的共时特点和历史演变,可以将变韵的基本规律归纳为首成分扩张与尾成分扩张两大类型,各韵母依声调环境而沿不同的方向演变。
