The aim of this study is to investigate air travellers’ behaviour with regard to choices for ground access to this airport. Questionnaire data were collected from 684 respondents. Multinomial logit modelling was employed for this purpose. These findings indicate that in families with at least one car of their own, the tendency for using bus and carpooling was decreased. In addition, it was found that those in the 36 - 40 age group were more inclined to take the taxi. Finally, the results of this study suggest that with the growing price of the private car, the tendency to use it was diminished. Therefore, if transportation authorities seek to reduce the use of personal cars, it is possible to make the use of private cars expensive with increasing the parking cost in the airport. This may lead to the reduction of using private cars in land access to Mehrabad airport.

This research estimates the extent of using teleworking to mean the feasibility and appropriateness of this method of work for employees and professors according to their characteristics and features of career. The study population included university staff and professors in Tehran, and data collection was carried out through 447 questionnaires. A logistic regression model was used to investigate the transport demand caused by teleworking. The results showed that various factors, including history and percentage of telework, and after that, the time delay of home-to-work and travel distance, affected the model of transportation demand of professor’s members. For the staffing community, it had the most significant impact on teleworking, history and percentage of telework, followed by travel distances, latency from work to home, and latency from home to work.

Background: The neonatal mortality rate is a main indicator of the health and development of a country. Having insight into the cause of neonatal deaths may be the first step to reducing it. This paper depicts the cause of newborn deaths in Iran., Methods: This cross-sectional study was performed on data from the national Iranian Maternal And Neonatal network to investigate all neonatal deaths in the country during the year 2019. The cause of death data were reported according to categories of birth weight, gestational age (GA), death time and place., Results: The main causes of the 9959 neonatal deaths during the study period were respiratory distress syndrome (RDS) (37%), malformation (21%), prematurity of <26 weeks (20%), others (12%), asphyxia (7%) and infection (3%). The major causes of neonatal mortality in delivery rooms were prematurity of <26 weeks and in the inpatient wards the RDS. By increasing the GA and birth weight towards term babies, the rate of RDS gets lower, while that of malformation gets higher., Conclusions: RDS was the main cause of neonatal mortality in Iran which is seen mainly in preterm babies. Prematurity of <26 weeks was another main cause. Thus, suggestions include reducing prematurity by preconception and pregnancy care and, on the other hand, improving the care of preterm infants in delivery rooms and inpatient wards., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.
