Survey Safety01:28

Survey Safety

515
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

391
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

Parametric Survival Analysis: Weibull and Exponential Methods01:14

Parametric Survival Analysis: Weibull and Exponential Methods

1.3K
Parametric survival analysis models survival data by assuming a specific probability distribution for the time until an event occurs. The Weibull and exponential distributions are two of the most commonly used methods in this context, due to their versatility and relatively straightforward application.
Weibull Distribution
The Weibull distribution is a flexible model used in parametric survival analysis. It can handle both increasing and decreasing hazard rates, depending on its shape parameter...

Area of Science:

  • Obstetrics and Gynecology
  • Perinatal Epidemiology
  • Maternal Health

Background:

  • Stillbirth, defined as fetal loss after 28 weeks gestation, affects approximately 2 million globally each year.
  • Sub-Saharan Africa is projected to bear half of the nearly 15.9 million stillbirths by 2030.
  • Known causes include placental issues, birth defects, and maternal health conditions, with many cases remaining unexplained.

Purpose of the Study:

  • To identify significant predictors for stillbirth risk in pregnant women.
  • To inform the development of improved antenatal health monitoring strategies.
  • To support targeted interventions for high-risk maternal populations.

Main Methods:

  • Retrospective analysis of data from 1435 mothers.
  • Chi-square tests to identify candidate covariates.
  • Stepwise logistic regression with Akaike Information Criterion (AIC) for covariate selection and adjusted risk ratio (aRR) calculation.

Main Results:

  • Heavy bleeding (aRR=4.69), hypertension history (aRR=3.89), and multifetal pregnancies (aRR>6) significantly increased stillbirth risk.
  • Other risk factors included premature rupture of membranes (aRR=3.22), severe back pain (aRR=2.61), anemia (aRR=2.45), and malaria (aRR=2.74).
  • Maternal relaxation reduced risk by over 60%; mothers aged 20-35 had 40% lower risk.

Conclusions:

  • Significant predictors for stillbirth forecasting have been identified.
  • Findings can guide the development of antenatal care strategies to mitigate stillbirth.
  • The study underscores the importance of tailored interventions for vulnerable maternal groups.
