It addresses a significant research gap in understanding metro passengers’ dynamics across cultural and geographical contexts. It employs questionnaires, field observations, and advanced data analysis techniques like association rule mining and neural network modeling. Key findings include a correlation between rainy weather, shorter waiting times, and higher arrival volumes. Neural network models showed high predictive accuracy, with waiting time, metro satisfaction, and weather being significant factors in Lagos Light Rail Blue Line Metro. In contrast, arrival patterns, weather, and time of day were more influential in Wuhan Metro Line 5. Results suggest that improving metro satisfaction and reducing waiting times could increase arrival volumes in Lagos Metro while adjusting schedules for weather and peak times could optimize flow in Wuhan Metro. These insights are valuable for transportation planning, passenger arrival volume management, and enhancing user experiences, potentially benefiting urban transportation sustainability and development goals.展开更多

This study is aimed to explore nutritional risk screening and its influencing factors of hospitalized patients in central urban area. It is helpful for the early detection of problems in nutritional supports, nutrition management and the implementation of intervention measures, which will contribute a lot to improving the patient＇s poor clinical outcome. A total of three tertiary medical institutions were enrolled in this study. From October 2015 to June 2016, 1202 hospitalized patients aged ≥18 years were enrolled in Nutrition Risk Screening 2002（NRS2002） for nutritional risk screening, including 8 cases who refused to participate, 5 cases of same-day surgery and 5 cases of coma. A single-factor chi-square test was performed on 312 patients with nutritional risk and 872 hospitalized patients without nutritional risk. Logistic regression analysis was performed with univariate analysis（P〈0.05）, to investigate the incidence of nutritional risk and influencing factors. The incidence of nutritional risk was 26.35% in the inpatients, 25.90% in male and 26.84% in female, respectively. The single-factor analysis showed that the age ≥60, sleeping disorder, fasting, intraoperative bleeding, the surgery in recent month, digestive diseases, metabolic diseases and endocrine system diseases had significant effects on nutritional risk（P〈0.05）. Having considered the above-mentioned factors as independent variables and nutritional risk（Y=1, N=0） as dependent variable, logistic regression analysis revealed that the age ≥60, fasting, sleeping disorders, the surgery in recent month and digestive diseases are hazardous factors for nutritional risk. Nutritional risk exists in hospitalized patients in central urban areas. Nutritional risk screening should be conducted for inpatients. Nutritional intervention programs should be formulated in consideration of those influencing factors, which enable to reduce the nutritional risk and to promote the rehabilitation of inpatients.展开更多

With the promotion and application of the Fast-Track Surgery concept and the increase in hospital bed turnover rate, the average hospital stay of patients undergoing CVR surgery has been significantly shortened, and thus the patients are still in the recovery stage rather than fully recovered when they are discharged from the hospital. Good preparation for discharge can improve patients’ post-discharge self-care ability, reduce the risk of re-admission, and save medical resources. <strong>Objective: </strong>To describe the status of readiness for hospital discharge among postoperative patients that have undergone CVR, and to explore its influencing factors.<strong> Methods:</strong> The general information questionnaire, the Readiness for Hospital Discharge Scale and the Quality of discharge Teaching Scale were utilized to investigate 130 post-CVR patients admitted to the Cardiothoracic Surgery Department of a tertiary A-Class hospital in Guangzhou from July 2019 to October 2020. <strong>Results: </strong>The Readiness for Hospital Discharge Scale was at a moderate level with a total score of 163.88 ± 39.082, while the Quality of Discharge Teaching Scale was also at a moderate level with a total score of 194.09 ± 40.643. Multiple linear regression analysis revealed that the quality of discharge guidance, gender, and occupation were the influencing factors of CVR patient’s readiness for hospital discharge. These three variables jointly explained 45.8% of the total variation. <strong>Conclusion: </strong>The level of CVR patients’ readiness for hospital discharge is at a moderate level, and the quality of discharge guidance positively affects patients’ readiness for discharge. Therefore, in clinical work, attention should be paid to patient discharge guidance. Personalized health education should be implemented to improve the quality of patient guidance.展开更多

文摘<strong>Background:</strong> There are about 200,000 patients in China who need to undergo valve replacement surgery each year. With the promotion and application of the Fast-Track Surgery concept and the increase in hospital bed turnover rate, the average hospital stay of patients undergoing CVR surgery has been significantly shortened, and thus the patients are still in the recovery stage rather than fully recovered when they are discharged from the hospital. Good preparation for discharge can improve patients’ post-discharge self-care ability, reduce the risk of re-admission, and save medical resources. <strong>Objective: </strong>To describe the status of readiness for hospital discharge among postoperative patients that have undergone CVR, and to explore its influencing factors.<strong> Methods:</strong> The general information questionnaire, the Readiness for Hospital Discharge Scale and the Quality of discharge Teaching Scale were utilized to investigate 130 post-CVR patients admitted to the Cardiothoracic Surgery Department of a tertiary A-Class hospital in Guangzhou from July 2019 to October 2020. <strong>Results: </strong>The Readiness for Hospital Discharge Scale was at a moderate level with a total score of 163.88 ± 39.082, while the Quality of Discharge Teaching Scale was also at a moderate level with a total score of 194.09 ± 40.643. Multiple linear regression analysis revealed that the quality of discharge guidance, gender, and occupation were the influencing factors of CVR patient’s readiness for hospital discharge. These three variables jointly explained 45.8% of the total variation. <strong>Conclusion: </strong>The level of CVR patients’ readiness for hospital discharge is at a moderate level, and the quality of discharge guidance positively affects patients’ readiness for discharge. Therefore, in clinical work, attention should be paid to patient discharge guidance. Personalized health education should be implemented to improve the quality of patient guidance.

文摘China is witnessing a very complicated economic development environment.Migrant workers'working patterns will directly affect their income level and the realization of many economic and social development goals.This paper collects relevant data from three places:Shanghai,Lanzhou and Chengdu for empirical research whose results show that determinants of migrant worker's willing working time in urban areas mainly include the“income-consumption difference”,“urban-rural consumption difference”and their“urban income and expenditure uncertainty”.These factors directly affect their effective working time in the city,and determine their choice of choosing corresponding work patterns.From the significant differences of these factors,we can see that migrant workers in China is still struggling to solve their material needs under the pressure of livelihood,and less attention is paid to their spiritual needs and the pursuit of quality of life.

文摘BACKGROUND Transjugular intrahepatic portosystemic shunt(TIPS)is a cause of acute-onchronic liver failure(ACLF).AIM To investigate the risk factors of ACLF within 1 year after TIPS in patients with cirrhosis and construct a prediction model.METHODS In total,379 patients with decompensated cirrhosis treated with TIPS at Nanjing Drum Tower Hospital from 2017 to 2020 were selected as the training cohort,and 123 patients from Nanfang Hospital were included in the external validation cohort.Univariate and multivariate logistic regression analyses were performed to identify independent predictors.The prediction model was established based on the Akaike information criterion.Internal and external validation were conducted to assess the performance of the model.RESULTS Age and total bilirubin(TBil)were independent risk factors for the incidence of ACLF within 1 year after TIPS.We developed a prediction model comprising age,TBil,and serum sodium,which demonstrated good discrimination and calibration in both the training cohort and the external validation cohort.CONCLUSION Age and TBil are independent risk factors for the incidence of ACLF within 1 year after TIPS in patients with decompensated cirrhosis.Our model showed satisfying predictive value.
文摘In order to clarify the mechanism and main influencing factors of the vibration energy coupling transmission with a dual-piston structure,a thermodynamic and dynamic coupling model of the free piston linear generator(FPLG)was established.The system energy conversion,vibration energy coupling transmission,and influencing factors were studied in detail.The coupling transmission paths and the secondary influence mechanism from in-cylinder combustion on vibration energy transmission were obtained.In addition,the influence of the movement characteristics of the dual-piston on the vibration energy transmission was studied,and the typical parameter variation law was obtained,which provides theoretical guidance for the subsequent vibration reduction design of the FPLG.
