| 2 | Therapeutic benefits of zinc sulfate on neonatal hyperbilirubinemia显示文摘Neonatal hyperbilirubinemia is a common phenomenon shortly after birth and a frequent cause of prolonged hospitalization[1].Increased enterohepatic circulation of indirect bilirubin is one of the elucidated mechanisms implicated in the pathophysiology of neonatal hyperbilirubinemia[2,3].According to various in vitro and in vivo evidence from animal[3]and human[2]trials,zinc salts have been depicted to reduce bilirubin levels. | Abdulrahman Al-Matary Abdullah AlGhamdi Bandar Alenaze Rasha Abdulaziz Mandili Dhuha Abdulaziz Alhawsawi Duha Magzoub Ahmed Abu-Zaid | 2022 | World Journal of Pediatrics2022，18，4： | 1 |
| 3 | Nurse manager ’ s perception about clinical supervision at Madinah Hospitals in Saudi Arabia显示文摘Aim:The present study assesses the nurse managers’perception of clinical supervision.Method:A cross-sectional,descriptive,non-experimental quantitative research design was utilized in three governmental hospitals in Madinah Munawara city for a purposive sample of different levels of nurse managers(n=84)by using a questionnaire.Results:The total knowledge of nurses managers regarding clinical supervision domains,where 59.5%of participants had a high level of knowledge,with mean±standard deviation(47.262±11.151).The highest mean was in the clinical supervision-facilitating learning domain(18.464±4.155),with 69%of participants having a high level of knowledge regarding this domain.Safety and quality in the clinical supervision domain represent the lowest mean of knowledge(4.607±1.628).The level of total skills of nurses managers regarding clinical supervision domains,where 54.8%of participants had a high level of total skill while the range 19-60,with mean±standard deviation was(44.167±8.958).The highest mean was in the c linical supervision-f acilitating learning domain(17.405±3.671),with 48.8%of participants having an increased knowledge of this domain.Safety and quality in the clinical supervision domain represent the lowest mean of skills(3.952±1.270),with more than half 58.3%of nurse managers having average skills in the same domain.Conclusion:In the Al-Madinah region,there is no single policy or system of clinical supervision;rather,it is based on the needs of each organization.Clinical supervision should be handled appropriately and supportive.Hospital management should offer proper training for newly appointed first-line nurse managers with adequate,regular,and timely feedback on their strengths and weaknesses in their skills.Clinical supervision should be taught as a separate curriculum in nursing administration courses.Hospital managers should create a system,culture and environment that fosters high ethical standards and competent clinical monitoring.The right to supervision,feedback,help,appropriate working circumstances,and respect must be guaranteed to trainees and supervisors in this system. | Awatif Omar Alhawsawi Amenh Mohammad Alahmdi Sahar Mohammed Aly | 2022 | Nursing Communications2022，6，1： | 0 |
| 4 | A modified universal pedestrian motion model: Revisiting pedestrian simulation with bottlenecks显示文摘Pedestrian flow through narrow exits is one the most important features of crowd dynamics and evacuation.This is a particularly important aspect of pedestrian simulation models in that the accuracy is highly dependent on their ability to produce realistic exit flow rates.We firstly identified the four parameters that are most critical for physical interactions of the social force model and then calibrated them against two well-controlled pedestrian experiments.With these calibrated parameters,we discussed the reasonable settings of sensitive parameters for different levels of pedestrian competitiveness.Then,we revisited the basic questions about the effect of the exit location,the bottleneck length,and the effect of obstacles on pedestrian egress.Our simulation results indicated that:(1)The effect of the exit location on the pedestrian egress efficiency is uncertain,and the evacuation efficiency is also related to the exit width and the level of urgency.(2)The'pass-way'after the exit also named as the bottleneck length has a negative impact on the evacuation performance only in the scenarios that the bottleneck length is not more than 2.0 meters.When the bottleneck length exceeds 2.0 meters,pedestrian outflow efficiency reaches an asymptotic.(3)Setting an obstacle near an exit is not leading to a longer pedestrian evacuation time,instead,it is effectively improving pedestrian evacuation. | Jianyu Wang Majid Sarvi Jian Ma Milad Haghani Abdullah Alhawsawi Juan Chen Peng Lin | 2022 | Building Simulation2022，15，4： | 0 |
