Abstract

Abstract: Dengue fever is a disease that can be fatal if not treated seriously. This disease is transmitted to humans through the Aedes Aegypti mosquito. Mathematical modeling is a tool used to understand the dynamics of dengue fever. Incomplete data creates uncertainty in the parameter values of the mathematical model. Uncertainty analysis to determine these parameters using sensitivity analysis. This study found that the bite rate of susceptible and infected mosquitoes and the mosquito death rate have a large influence on changes in the value of . Human recovery rate (r), mosquito mortality rate , and human mortality rate have a major influence on infected human individuals . The bite rate of susceptible and infected mosquitoes has the most positive influence on the number of infected mosquitoes . The mortality rate of mosquitoes had the most negative relationship with the number of mosquitoes infected with . Numerical simulations are carried out to determine the dynamics that occur when parameter values are increased or decreased. Keywords: Sensitivity Analysis, Dengue Fever, Mathematical Modeling

Abstract

The study aims to determine the effective dose to critical organs in head CT scans at RSUD Bali Mandara and analyse the difference in effective dose between male and female patients and compare it with BAPETEN's normal threshold. Secondary data including current, voltage, CTDIvol, and DLP were collected and grouped by gender. The effective dose was calculated by multiplying DLP by the conversion factor K and CTDIvol by the organ weight factor (WT). The mean effective dose of male patients was 4.35 ± 0.68 mGy, while that of female patients was 4.00 ± 0.53 mGy. The effective dose of critical organs for males was 0.642 mGy and for females 0.613 mGy, with higher doses for males. Statistical analysis using t-test shows the value of tcount < ttable, which indicates that the effective dose in head CT scan examination at RSUD Bali Mandara is still within normal limits according to the BAPETEN DRL standard Number: 1211/K/V/2021.

Abstract

The results of research that have been carried out, especially in the field of medical physics such as X-rays, have been widely utilized in the medical field, especially Radiology Units in Several General and Regional Hospitals. Thus, it is very important to be understood and known by the community, especially the community, in this case the students of SMA Negeri 2 Kuta. In 2022/2023, there are 507 male and 597 female students. Seeing these conditions, surveys and observations were carried out as a result, students had difficulty understanding physics because the physics subject matter was dense, memorized and mathematical. Seeing these results, it is necessary to carry out a new paradigm in physics learning. One of the more appropriate methods is to balance theory learning with field applications such as natural and artificial radiation measurements and applications in the field of medical physics. The results of natural radiation measurements in the classroom and outside the classroom were 0.605 ± 0.0024 and 0.182 ± 0.0008 mSv/year, respectively. The limit of the dosage rate allowed by BAPETEN is 1,000 mSv/year. Natural radiation identified in the classroom and outside the classroom is still declared safe
