Abstract

Natural disasters claimed many victims. To prevent this, one is to understand the problem of evacuation crowd behavior. Evacuation research in dangerous condition of the people or the crowd is a research to understand how human behavior in facing danger as individuals in a group or crowd. Evacuation research is almost impossible to be experimented in a real life, but it can be simulated. Evacuation simulation can help to understand more about the evacuation. For example, by understanding the evacuation, it could be used for the development of buildings and facilities safer and more comfortable or to make good standard evacuation procedures. Formerly research evacuation simulations in the crowd are based on the miSFM (mutual information Social Force Model) where the individual or agent in the crowd will conduct the evacuation simulation by using social force models and get feedbacks of mutual information such as location, rate, direction and density of agent, so there’s no effect of "faster is slower" but this model still has the disadvantage that doesn’t regulate the density in crucial areas, such as in the exit. This study proposes a force social combination model with attractive potential field or SPM-PF to solve the density, so the effect of "faster is slower" can be reduced and the evacuation could be faster. Based on the results of the tests taken place on environment with one door room showed that the average of SFM-PF algorithm is faster 13.01 seconds or 44.67% than the miSFM algorithm in the application of evacuation simulation.Keyword: crowd behavior, simulation evacuation, social force model, atrractive potential field

Abstract

Background: Low birth weight babies are population at risk for gastroesophageal reflux and its complications due to physiologic immaturity of digestive system. However, the pathomechanism remains unclear. There is no similar study conducted in Surakarta City and still lack of studies on 0-1 year infants. The aim of this study is to evaluate Gastroesophageal reflux risk in low birth weight infants age 0–1 year. Method: Case control study on infants aged 0–1 year in Ngoresan Public Health Center, Surakarta. Samples were obtained by purposive sampling method in April–May 2021 with a questionnaire on infant characteristics and the Infant-Gastroesophageal Reflux Questionnaire as research instruments. Results: There were 60 samples divided into case and control groups with a 1:1 ratio. There was no significant relationship between birth weight and gastroesophageal reflux (p = 0.612). Discussion: Research conducted in Semarang and Italy declared no correlation between birth weight and gastroesophageal reflux. The relationship is more visible if infants have a birth weight <1,500 grams and a history of the disease such as bronchopulmonary dysplasia or chronic lung disease. Conclusion: There is no relationship between birth weight and gastroesophageal reflux in infants aged 0–1 years
