ABSTRACT
Objective:To investigate the current situation of students' academic procrastination behavior in medical colleges and universities and its influencing factors, and to put forward suggestions to reduce the academic procrastination of medical students.Methods:A total of 1 327 undergraduate students from three medical colleges and universities in Heilongjiang Province were randomly selected to receive questionnaire investigation on life satisfaction, anxiety, and academic procrastination. SPSS 23.0 was used for data analysis.Results:①The total procrastination scores of medical students were (35.00±8.92) points. ②There were statistical differences in the academic procrastination of medical students with different genders, whether the only children, the reasons for choosing the major, and the level of achievement ( P < 0.05). There was no statistical difference in academic procrastination among medical students of different ages and grades ( P > 0.05). ③Medical students' procrastination was positively correlated with their anxiety level ( r = 0.102, P < 0.01), and negatively correlated with life satisfaction ( r = -0.117, P < 0.01). ④Regression analysis showed that the following six predictive variables including the level of achievement, gender, life satisfaction, anxiety, reasons for choosing the major, and whether the only children could effectively explain the variance of 14.2% academic procrastination of medical students. Conclusion:The overall degree of academic procrastination of medical students is higher than that of non-medical students. And the students' achievement level, gender, life satisfaction, anxiety, the reasons for choosing this major and whether the only child are the influencing factors of academic procrastination.
ABSTRACT
Objective To examine the current situation of the career plateau among anesthesiologists and analyze the impact of occupational stressors on it. Methods A questionnaire survey was conducted on the anesthesiologists. A total of 300 questionnaires were distributed and 278 questionnaires were effectively collected. Statistical analysis using SPSS 19.0 was performed to assess the status quo of career plateau among anesthesiologists. Pearson correlation analysis and stepwise regression analysis were used to analyze the influence of occupational stressors on career plateau . Results The average value of occupational stressors among anesthesiologists was (3.22±0.55), and the average value of career plateau was (3.90±0.70). Occupational interest in the occupational stressors of anesthesiologists is negatively correlated with the occupational plateau (r=-0.552, P<0.01), and career development is negatively correlated with occupational plateau (r=-0.541, P<0.01) as well. Both occupational interest and career development show a negative predictive effect on the career plateau (β=-0.359, P<0.01 andβ=-0.334, P<0.01, respectively). Conclusion Career plateau among anesthesiologists is at a medium-to-high level. Occupational interest and occupational development in occupational stressors have a negative predictive effect on occupational plateaus, so hospital managers should pay attention to them.
ABSTRACT
Objective To explore the impact of work-family conflict on job satisfaction and turnover intention of anesthesiologists in Heilongjiang Province.Methods Questionnaire survey was used for data collection.Descriptive statistics,Pearson correlation analysis and multivariate linear hierarchy regression analysis were performed to analyze the impact of work-family conflict on job satisfaction and turnover intention of anesthesiologists.Results The average value of work-family conflict among anesthesiologists was (2.99 ± 0.57).The finding indicated that work-family conflict of anesthesiologists had a significant negative effect on job satisfaction (β=-0.248,P＜0.01) and a positive effect on turnover intention (β=0.329,P＜0.01).Conclusion Anesthesiologists' work-family conflict is above the middle level in Heilongjiang Province.The work-family conflict of anesthesiologists can reduce job satisfaction and increase turnover intention.
ABSTRACT
Aim To study absorption characteristics of SM-1 , a novel anti-tumor agent , to provide a research basis for the druggability evaluation of SM-1 and formu-lation design. Methods Caco-2 cell monolayer model and in situ single-pass intestinal perfusion rat model were used to study the absorption characteristics of SM-1 , and the absorption of SM-1 in vivo was evaluated through absolute bioavailability study in rats. Results The results of cell monolayer model showed that cu-mulative absorption and efflux of SM-1 increased line-arly with concentration ( 10 ~40 mg · L-1 ) . There were no significant differences in Papp with different concentrations ( P>0. 05 ) . SM-1 was absorbed mainly through passive diffusion. The intestinal perfusion re-sults showed that Ka and Pef of SM-1 had no significant differences ( P > 0. 05 ) , when the concentrations ranged from 25 to 100 mg · L-1 . SM-1 entered the systemic circulation mainly via on passive diffusion, indicating it is a compound with high permeability. The absorption of SM-1 in duodenum was superior to other intestinal segments ( P 0. 05 ) . The absolute bioavailability of SM-1 in rats was 29. 3%. Conclusion The membrane perme-ability of SM-1 is high and it can be absorbed by intes-tine well. The absorption mechanism of SM-1 is pas-sive diffusion, and it possibly escapes from the efflux transporter protein. The absolute bioavailability of SM-1 in rats is low.
ABSTRACT
Objective To realize hospital administrators ’recognition extent to healthcare-associated infection (HAI )management staff ’s competency and qualification.Methods The unified questionnaires were filled in by respondents in 173 hospitals of Inner Mongolia autonomous Region,administrators’recognition on the competency and qualification of HAI management staff were surveyed.Results Of 445 hospital administrators,20.09%, 19.89%,and 18.05% considered that staff members in HAI management departments should have the knowledge background of preventive medicine,clinical medicine,and nursing respectively.58.20%,89.44%,and 43.37% of hospital administrators considered that the directors of HAI management departments should have senior profession-al titles,undergraduate course or above,and with 2 -5 working experience,respectively.34.92% and 30.93%considered that the most important professional ability of directors of HAI management department were profession-al and management ability,respectively.Conclusion Hospital administrators are apt to consider that the competen-cy and qualification of HAI management staff are strong professional ability and certain management ability,and are interdisciplinary talents.
