Mathematics is a scientific field that investigates formless structures and forms of interaction within them. Mathematical interaction is a powerful tool used to express mathematical opinions verbally or in writing. The Think-Talk-Write (TTW) learning approach is designed to facilitate the construction, reflection, and organization of new mathematical views. This study aims to explore the efficacy of using TTW learning examples as a tactic to enhance the quality of students' mathematical communication, and to assess the impact of this approach. In order to achieve these goals, researchers used classroom action research in two stages of testing. The study involved 21 students in grade VIII at SMP Parulian 1 Medan. The initial ability test revealed that the students' mathematical communication ability scores were 34.2%. After conducting test activities in cycle I, the average mathematical communication ability of students rose to 36.8%. In the second cycle (II), the percentage result increased to 88%. The results of the research demonstrate that students in Class VIII at SMP Parulian 1 Medan experience a significant improvement in their mathematical communication skills through learning via the Think-Talk-Write model. We can conclude that this approach is an effective way to enhance students' mathematical communication skills.    

The quality of life in North Sumatra currently still needs improvement, where poverty rates and human development are still lagging. These problems can be reflected in the community welfare indicator, namely the Human Development Index (IPM). One of these problems can be solved by knowing the factors that determine the Human Development Index in North Sumatra. The Human Development Index is suspected to contain elements of spatial dependency, therefore in this study the spatial regression method will be used with a spatially dependent effect model. The results of the analysis and discussion obtained are that the SAR model is the appropriate model in the case of the Human Development Index in North Sumatra. Predictor variables that significantly influence the Human Development Index in North Sumatra are Pure Enrollment Rate (APM) at Senior High School level , Poverty Rate , Open Unemployment Rate , and PDRB on the basis of price .

B value is a factor that reflects the strength and timing of the gradient that will be used to generate a diffusion-weighted image. The higher the b value, the stronger the effect on diffusion. B value can be expressed in units of s/mm2 with a b value range of 500 s/mm2 to 1500 s/mm2. The use of b value in Diffusion Weighted Imaging (DWI) sequences is very important in detecting prostate cancer to distinguish malignant and benign cancer tissue because b value determines the amount of diffusion weighting and shows the sensitivity of the sequence to diffusion. The purpose of this study is to determine the difference in the quality of SNR and CNR images with b value variations in Pelvic MRI examination in prostate cancer cases. This study uses quantitative research methods with an experimental approach. The study population and samples were 4 Pelvic MRI patients with prostate cancer cases who underwent examination in July-August 2023 at the Radiology Installation of Prof.Dr.I.G.N.G Ngoerah Hospital, and each sample was subjected to b value variations of 800, 1000, 1400 and 2000 on the Diffusion Weighted Imaging (DWI) sequence. Data were processed using radiant DICOM and then analyzed using normality test and repeated anova test on SPSS 25 software. The results showed a significance value (p-value) > than 0.05, it can be concluded that H0 is accepted and Ha is rejected, which means that there is no difference in Pelvic MRI image quality in Prostate Cancer Cases with b value variations. The b value variation of 800 on Pelvic MRI examination on Diffusion Weighted Imaging (DWI) sequences with prostate cancer cases can produce more optimal image quality compared to b value variations of 1000, 1400 and 2000.
