Recently, there has been an increasing interest in targeting the safety of bus operations worldwide; however, little is known about the determinants of the bus crash severity in developing countries. By estimating an ordered logit model using the bus-involved collision data in Hanoi (Vietnam), spanning the period from 2015 to 2019, this study investigates various factors associated with the crash severity. The results reveal that the severity risk increases for (1) large buses, (2) raining conditions, (3) evening or night, (4) sparse traffic, (5) non-urban areas, (6) roads with at least three lanes, (7) curved roads, (8) two-way roads without a physical barrier, (9) head-on collision, and (10) pedestrian-related crashes. Aside from confirming the crucial roles of a wide range of factors, this research has examined the effects of two determinants (traffic density and crash area) that have not been considered for the cases of developing countries previously. Based on the findings on the impacts of factors, a series of policy recommendations regarding improving road conditions in non-urban areas, promoting walking infrastructure, reminders of high-risk situations for drivers, safety notes when improving bus service quality, and recording bus-related crashes are proposed.

Biscogniauxia canker or dieback (formerly called Hypoxylon canker or dieback) is a common contributor to poor health and decay in a wide range of tree species (Balbalian & Henn 2014). This disease is caused by several species of fungi in the genus Biscogniauxia (formerly Hypoxylon). B. atropunctata or B. mediterranea are usually the species found on Quercus spp. and other hosts in Florida, affecting trees growing in many different habitats, such as forests, parks, green spaces and urban areas (McBride & Appel, 2009).  Typically, species of Biscogniauxia are opportunistic pathogens that do not affect healthy and vigorous trees; some species are more virulent than others. However, once they infect trees under stress (water stress, root disease, soil compaction, construction damage etc.) they can quickly colonize the host. Once a tree is infected and fruiting structures of the fungus are evident, the tree is not likely to survive especially if the infection is in the tree's trunk (Anderson et al., 1995).

<p>Designing urban facades is considered as a major factor influencing issues<br />such as natural ventilation of buildings and urban areas, radiations in the<br />urban canyon for designing low-energy buildings, cooling demand for<br />buildings in urban area, and thermal comfort in urban streets. However, so<br />far, most studies on urban topics have been focused on flat facades<br />without details of urban layouts. Hence, the effect of urban facades with<br />details such as the balcony and corbelling on thermal comfort conditions<br />and air flow behavior are discussed in this literature review. <strong>Aim</strong>: This<br />study was carried out to investigate the effective factors of urban facades,<br />including the effects of building configuration, geometry and urban<br />canyon’s orientation. <strong>Methodology and Results</strong>: According to the results,<br />the air flow behavior is affected by a wide range of factors such as wind<br />conditions, urban geometry and wind direction. Urban façade geometry<br />can change outdoor air flow pattern, thermal comfort and solar access.<br /><strong>Conclusion, significance and impact study</strong>: In particular, the geometry of<br />the facade, such as indentation and protrusion, has a significant effect on<br />the air flow and thermal behavior in urban facades and can enhance<br />outdoor comfort conditions. Also, Alternation in façade geometry can<br />affect pedestrians' comfort and buildings energy demands.</p>

Background: Congenital anomalies are a major cause of infant morbidity and mortality in developing countries including our country. Registries and data on these anomalies are still primitive and poorly collated. In this study we aimed to assess the important demographic factors associated with the development of congenital anomalies. Methods: This was a cross-sectional hospital-based study involving 880 infants in the 1st year of life registered in the birth defect unit in Fallujah Maternity and Children Hospital in the period between 1st of January 2017 to the 31st of December 2019. The prevalence rate, the pattern of anomalies and the factors associated with their occurrence were determined. Results: The prevalence rate of the group enrolled in this study was 31/1000 total births, congenital heart defects was the commonest followed by central nervous system anomalies, 58% of the infants were males, 65% had ≥ 2.5 kg birth weight & 95% were singletons. Family history of congenital anomalies was found in 31.25% of cases. The largest group of mothers (55.7%) were 21-30 years old & 92.5% of fathers were less than 45 years old. Parental consanguinity reported in 64.3% of the total cases. Only 4.5% of mothers reported history of fever during pregnancy, and none of them had history of exposure to x-ray or teratogenic drug use. Gestational hypertension was reported in 10% of the total (880) mothers, hypertension and diabetes mellitus in 0.3%, while hepatitis C, hepatitis B, toxoplasmosis and epilepsy, each was reported in only one mother (0.1% of the total). Regarding the outcome of pregnancy, 66.6% were live births, 24.2% were abortions and 9.2% were stillbirths. History of previous abortions was reported in 22% of cases. Urban residents accounted for 63% of the families of congenitally abnormal infants while 37% were rural. Conclusion: Congenital anomalies are still a major cause for concern and tension in Fallujah society, there is serious need to establish a surveillance and good statistical system for congenital anomalies and efforts should be made to raise awareness of their occurrence and the associated risk factors in Iraq and other developing countries.

Public Park is considered one of the essential settings for physical activity, especially in urban areas. Parks support physical activity through their accessibility, their provision to facilitate active pursuits; their capacity to provide opportunities to a wide range of users; and their semi-permanent nature. The paper explores the design intervention assessment of Benchakitti Park, which serves as the pilot project for active park and showcase during the past ISPAH 2016 conference. The objective of the paper is to understand the health and well-being benefits of an urban park in increasing PA levels of urban population and promoting a healthy and active lifestyle. Keywords: Public park; physical activity; urban landscape design; public health; SOPARC

IntroductionEarly access to adequate antenatal care (ANC) from skilled providers is crucial for detecting and preventing obstetric complications of pregnancy. We aimed to assess factors associated with the utilisation of the new WHO ANC guidelines including the recommended number, on time initiation and adequate components of ANC contacts in Myanmar.MethodsWe examined data from 2943 mothers aged 15–49 years whose most recent birth occurred in the last 5 years prior to the 2015–2016 Myanmar Demographic and Health Survey. Factors associated with utilisation of the new WHO recommended ANC were explored using multinomial logistic regression and multivariate models. We used marginal standardisation methods to estimate the predicted probabilities of the factors significantly associated with the three measures of ANC.ResultsApproximately 18% of mothers met the new WHO recommended number of eight ANC contacts. About 58% of the mothers received adequate ANC components, and 47% initiated ANC within the first trimester of pregnancy. The predicted model shows that Myanmar could achieve 70% coverage of adequate components of ANC if all women were living in urban areas. Similarly, if ANC was through private health facilities, 63% would achieve adequate components of ANC. Pregnant women from urban areas (adjusted risk ratio (aRR): 4.86, 95% CI 2.44 to 9.68) were more than four times more likely to have adequate ANC components compared with women from rural areas. Pregnant women in the highest wealth quintile were three times more likely to receive eight or more ANC contacts (aRR: 3.20, 95% CI 1.61 to 6.36) relative to mothers from the lowest wealth quintile. On time initiation of the first ANC contact was fourfold for mothers aged 30–39 years relative to adolescent mothers (aRR: 4.07, 95% CI 1.53 to 10.84).ConclusionThe 2016 WHO ANC target is not yet being met by the majority of women in Myanmar. Our results highlight the need to address health access inequity for women who are from lower socioeconomic groups, or are younger, and those living in rural areas.

Research shows that traffic fatality risk is generally higher in rural areas than in urban areas. In developing countries, vehicle ownership and investments in public transportation typically increase with economic growth. These two factors together increase the vehicle population, which in turn affects traffic safety. This paper presents a study focused on the relationship of various factors—including household consumption expenditure data—with traffic fatality in rural and urban areas and thereby aims to fill some of the gaps in the literature. One such gap is the impacts of personal and non-personal modes of travel on traffic safety in rural versus urban areas in developing countries which remains unexplored. An exhaustive panel data modeling approach is adopted. One important finding of this study is that evidence exists of a contrasting relationship between household expenditure and traffic fatality in rural and urban areas. The relationship between household expenditure and traffic fatality is observed to be positive in rural areas and a negative in urban areas. Increases in most expenditure variables, such as fuel, non-personal modes of travel, and two-wheeler expenditures, are found to be associated with an increase in traffic fatality in rural areas.
