ABSTRACT
Based on Donabedian three-dimensional quality structure theory, this paper summarized the sensitive quality indicators of breast cancer nursing and summarized the research status from three aspects of structure, process and quality of results, to analyze the shortcomings of current research, and propose improvement strategies. The aim is to provide reference for the construction of scientific, standardized, practical and specialized sensitive quality indicators of breast cancer nursing in accordance with China′s national conditions.
ABSTRACT
Objective To explore the influence of visual working memory contents on visual func-tion and fluid intelligence.Methods 42 subjects were randomly divided into three groups:controll group in-cluding 17 people who had no training,working memory based on Gabor vision group including 13 people and standard working memory group including 12 people who received the N-back working memory training for 15 days,and lasted half an hour in every day.The contrast sensitivity was recorded and measured using OPTEC6500,and the fluid intelligence was measured with the Raven's advanced progressive matrices before and after training.Results In the Gabor working memory group,there were salient gains in contrast sensitivi-ty(respectively(1.48±0.26)log,(1.87±0.13)log,P＜0.05)and in fluid intelligence(respectively(11.15± 1.28),(13.46±1.76),P＜0.05)between pre-and post-test. In the standard working memory group,the con-trast sensitivity improvement was not significant(respectively(1.72±0.30)log,(1.75±0.31)log,P＞0.05),the fluid intelligence increased significantly(respectively(11.25±1.91),(13.00±1.86),P＜0.05); while the controlling group had no significant difference in contrast sensitivity (respectively(1.61±0.26)log,(1.67± 0.25)log,P＞0.05)and in fluid intelligence(respectively(11.41±1.87),(11.58±1.94),P＞0.05) between pre-and post-test.Conclusion Working memory training based on Gabor vision can enhance the subjective perception of visual stimuli and improve the behavioral effect of visual contrast sensitivity, but the visual working memory contents do not affect the migration effect of working memory training on fluid intelligence.
ABSTRACT
Skin sensitization (allergic contact dermatitis, ACD), is a serious condition caused by small reactive molecules and is characterized by a delayed-type hypersensitivity .Animal tests were usually used in the evaluation of sensitizing potential of chemical substances in the past .However , there is an increasing interest from the public for reducing and ultimately replacing animal tests .The European Union (EU) has posed a ban on animal testing of cosmetic ingredients that includes skin sensitization since 2013.Therefore, alternative in vitro tests are the main tendency in chemical substances and cosmetic sensitizing potential research in the future .In this study, different kinds of in vitro test methods that were adopted by OECD or on research (LLNA, DPRA, KeratinoSens TM, h-CLAT) were reviewed through recent years literature , comprehensive introduction and evaluation were made to obtain reliable hazard and potency information on potential skin sensitizers .
ABSTRACT
Objective To explore the influence on college students' contrast sensitivity how dual N-back working memory training task based on Gabor,and to provide new training method for improving the contrast sensitivity.Methods 42 college students were randomly divided into three groups:a control group (17 students) ; a working memory training group (13 students) ; and a Gabor orientation training group (12 students).The control group received no training,while the working memory training group and the Gabor orientation training group received N-back working memory training and Gabor training,respectively,over three weeks (5 days a week,approx.half an hour per day).The above-mentioned two training methods performed with the same visual stimulus,i.e.,the Gabor patch with a fixed spatial frequency and contrast.The contrast sensitivity of the 42 students was measured and recorded using OPTEC6500 before and after training.Results In the working memory training group,a salient gain in contrast sensitivity was observed after the training (before:(1.48 ± 0.26) log,after:(1.87 ± 0.13)log),with a statistically significant difference (t =-6.20,P ＜ 0.05),while both the Gabor orientation training group (before:(1.75 ± 0.19) log,after:(1.68 ± 0.30) log) and the control group (before:(1.67 ±0.25) log,after:(1.61 ± 0.26) log)) showed no statistically significant difference (P ＞ 0.05) in terms of contrast sensitivity.Conclusion N-back working memory training shows a positive effect on improving contrast sensitivity in Gabor identification training,and can be used as a means to improve contrast sensitivity.
