ABSTRACT
Objective:To investigate the ecological environment and associated plants of mountain cultivated Panax ginseng were investigated in Xifeng county，Kuandian Manchu autonomous county and Huanren Manchu autonomous county of Liaoning province，in order to provided suggestions on the development of the mountain cultivated P. ginseng in these areas and necessary reference materials for the analysis of ecological suitability of mountain cultivated P. ginseng. Method:The field survey was conducted through sample plot survey in the survey pattern ofbased on representative area-sample plot-quadrat，literature review and data collation， were conducted to record indicators， calculate relevant parameters and make summary. Result:The associated plants were investigated based on 42 samples of mountain cultivated ginseng collected. A total of 95 plant species were identified. The correlation analysis was made on the six main species with an occurrence frequency of higher than 33%， and they were all positively correlated. Asarum heterotropoides var. mandshuricum was the strongest，which was followed by Schisandra chinensis， and Tilia tuan was the strongest in the arbor layer. The survey also found many problems in these areas，such as fewer large-scale planting bases， more scattered households，mixed germplasms，irregular planting techniques，simple planting mode and less sources of economic income generation. Conclusion:Xifeng county，Kuandian county and Huanren county of Liaoning province boast a superior ecological environment and abundant resources of mountain cultivated P. ginseng. The survey gets the whole picture of the ecological environment and associated plants of mountain cultivated P. ginseng in representative areas of Liaoning province，so as to provide the basis for the further development of mountain cultivated P. ginseng cultivation industry and the promotion of mountain cultivated Panax ginseng economy.
ABSTRACT
Objective: To explore the situation of interpersonal adaption and its relation to extroversion and self-control in college students. Methods: Totally 3125 college students (1497 males, 1628 females; age from 16 to24 years) were assessed with the interpersonal adaption dimension from China College Student Adjustment Scale (CCSAS), Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI) and Self-Control Scale (SCS). Results: The average score of interpersonal adaption was (33. 3 ± 3. 6). Regression analysis showed that extraversion and self-control positively predicted interpersonal adaption (β = 0. 25, 0. 08), interaction of extraversion and selfcontrol negatively predicted interpersonal adaption significantly (β =-0. 08). In the introvert group, the interpersonal adaption scores were higher in students with higher self-control scores than in those with lower self-control scores (P ＜ 0. 001). Conclusion: It suggests that college students have good interpersonal adaptation. Self-control may buffer the negative effect of low extraversion on interpersonal adaption.
ABSTRACT
Objective To improve the qualified rate of cleaning of loaner orthopedic surgery instruments by application of quality control circle(QCC).Methods QCC activity was carried out in a hospital from May to October 2016, on-site assessment of cleaning quality was performed by two circle members, causes of unqualified cleaning result of loaner orthopedic surgery instruments were recorded, the qualified result of loaner orthopedic surgery instruments before QCC activity(May-June 2016)and after QCC activity(September-October 2016)was compared. Results Before QCC activity, there were 1 667 packages of loaner instruments, 1 415 were qualified for cleaning, qualified rate was 84.88％;after activity, there were 1 673 packages of loaner instruments, 1 655 were qualified for cleaning, qualified rate was 98.92％, difference was statistically significant between two groups(P＜0.01), qualified rate increased to 14.04％, target achievement rate was 116％.Conclusion Application of the scientific tool of QCC can improve the qualified rate of cleaning of loaner orthopedic surgery instruments.
