Research on the Reform and Practice of “Basic Nursing Skills Practice” Course Assessment

Objective: “Basic Nursing Skills Practice” is a key course connecting classroom and clinical teaching in nursing specialty teaching. Nursing practice ability is one of the core abilities of nurse practitioners. Therefore, the teaching quality of this course is directly related to the quality of nursing work. To improve the teaching quality of practical course, the assessment reform of the “Basic Nursing Skills Practice” course was carried out among the nursing undergraduates to explore a reasonable and fair assessment mechanism. Method: In the assessment of “Basic Nursing Skills Practice” course, the assessment included individual skill operation assessment, virtual simulation assessment and team comprehensive skill assessment. The assessment proportion was adjusted from 100% for the final examination to 50% for the middle and final examinations respectively. The assessment method was changed from individual skills assessment at the end of the term to a combination of individual skills assessment at the midterm and virtual simulation assessment and team skills assessment at the end of the term. The method has changed from summative evaluation to a combination of formative evaluation and summative evaluation, and self-made questionnaire was used to investigate the effect. Results: After implementing the assessment reform, 86.84% of the students were satisfied with the assessment reform, and the percentage of students with scores above 80 reached 100%. The highest score is 93.0, while the lowest score is 83.0, and the average score was 88.0. Conclusions: High satisfaction of students with basic nursing skills examination reform promoted the learning effectiveness and professional emotions, cultivated comprehensive quality and ability, promoted the realization of talent training objectives.

Improved Reliability Analysis Method Based on the Failure Assessment Diagram

With the uncertainties related to operating conditions,in-service non-destructive testing（NDT） measurements and material properties considered in the structural integrity assessment,probabilistic analysis based on the failure assessment diagram（FAD） approach has recently become an important concern.However,the point density revealing the probabilistic distribution characteristics of the assessment points is usually ignored.To obtain more detailed and direct knowledge from the reliability analysis,an improved probabilistic fracture mechanics（PFM） assessment method is proposed.By integrating 2D kernel density estimation（KDE） technology into the traditional probabilistic assessment,the probabilistic density of the randomly distributed assessment points is visualized in the assessment diagram.Moreover,a modified interval sensitivity analysis is implemented and compared with probabilistic sensitivity analysis.The improved reliability analysis method is applied to the assessment of a high pressure pipe containing an axial internal semi-elliptical surface crack.The results indicate that these two methods can give consistent sensitivities of input parameters,but the interval sensitivity analysis is computationally more efficient.Meanwhile,the point density distribution and its contour are plotted in the FAD,thereby better revealing the characteristics of PFM assessment.This study provides a powerful tool for the reliability analysis of critical structures.

Diffusion tensor tractography studies on mechanisms of recovery of injured fornix

The fornix,which connects the medial temporal lobe and the medial diencephalon,is involved in episodic memory as an important part of the Papez circuit.The mechanisms of recovery of an injured fornix revealed by diffusion tensor tractography in the five studies are summarized as follows：1） recovery through the nerve tract from an injured fornical crus to the medial temporal lobe via the normal pathway of the fornical crus;2）recovery through the nerve tract originating from an ipsi-lesional fornical body connected to the ipsi-lesional medial temporal lobe via the splenium of the corpus callosum;3） recovery through the nerve tract from the ipsi-lesional fornical body extending to the contra-lesional medial temporal lobe via the splenium of the corpus callosum;4） recovery through the nerve tract originating from the ipsi-lesional fornical column connected to the ipsi-lesional medial temporal lobe;and 5） recovery through the nerve tract originating from the contra-lesional fornical column connected to the ipsi-lesional medial temporal lobe via the contra-lesional medial temporal lobe and the splenium of the corpus callosum.These diffusion tensor tractography studies on mechanisms of recovery of injured fornical crus appeared to provide useful information for clinicians caring for patients with brain injury,however,studies on this topic are still in the beginning stages.

Research on the Performance Assessment Mechanism of Accurate Poverty Alleviation in Vocational Education

Vocational education is an effective way to achieve accurate poverty alleviation and get rid of intergenerational poverty.Vocational education is mainly to train skilled talents,not only to provide academic education for the children of poor families,but also to use a skill to achieve employment.It is of great necessity to implement accurate poverty alleviation in vocational education,and performance assessment is a very important part of the accurate poverty alleviation work of vocational education.This paper mainly analyzes the predicament of accurate poverty alleviation in vocational education and the problems in the construction of performance assessment system for accurate poverty alleviation in vocational education,and puts forward measures to improve the accurate poverty alleviation assessment system for vocational education and strengthen the accurate of vocational education.
