Electroencephalogram (EEG) signals derived from polysomnography recordings play an important role in assessing the physiological and behavioral changes during onset of sleep. This paper suggests a spike rhythmicity based feature for discriminating the wake and sleep state. The polysomnography recordings are segmented into 1 second EEG patterns to ensure stationarity of the signal and four windowing scheme overlaps (0%, 50%, 60% and 75%) of EEG pattern are introduced to study the influence of the pre-processing procedure. The application of spike rhythmicity feature helps to estimate the number of spikes from the given pattern with a threshold of 25%.Then non parametric statistical analysis using Wilcoxon signed rank test is introduced to evaluate the impact of statistical measures such as mean, standard deviation, p-value and box-plot analysis under various conditions .The statistical test shows significant difference between wake and sleep with p<0.005 for the applied feature, thus demonstrating the efficiency of simple thresholding in distinguishing sleep and wake stage .

One of the nutritional problems that often occurs among adolescents is iron deficiency anemia. Especially for adolescent girls who have a higher risk of anemia than adolescent boys. Based on data from Riskesdas 2018, the prevalence of anemia in adolescents aged 15-24 years is 32%, meaning that there are still anemia problems in Indonesia that have not been resolved. The purpose of this community dedication activity is to provide education about iron deficiency anemia for adolescent girls using leaflet media. The target of this community dedication activity is adolescent girls aged 12-19 years in the JABODETABEK area. The community dedication activity is carried out online through the WhatsApp group due to the COVID-19 pandemic. There are 31 adolescent girls who participated in this community dedication activity. This community dedication activity consists of three stages including pretest, education with leaflets, and posttest. The amount and types of pretest and posttest questions are the same. The amount of questions given is 15 questions. The correct answer is given a score of 10 and the wrong one is given a score of 0. The level of knowledge of adolescent girls is categorized as 3 groups, which is less if the correct answer is <60%, sufficient if the correct answer is 60-80%, and good if the correct answer is >80%. Most of the adolescent girls are in the age range of 17-19 years (54.8%). The results showed that there was an increase in knowledge about iron deficiency anemia in adolescent girls. The results of the Wilcoxon signed rank test showed significantly different pretest and posttest results (p-value = 0.000), so it can be concluded that providing education using leaflets can help increase knowledge of iron deficiency anemia for adolescent girls.Salah satu masalah gizi yang sering terjadi pada kalangan remaja yaitu anemia defisiensi besi.

Hemoglobin is the red pigment-protein contained in red blood cells. The function of hemoglobin is to transport oxygen from the lungs and in the bloodstream to be carried to the tissues. Hemoglobin can increase by increasing the intake of iron in the body. One way to increase hemoglobin can be done by giving method Infused Water Dates. Infused water is a drink consisting of plain water with fresh fruit added and soaking or settling together for a certain time. The making of infused water is carried out by soaking for a period of 0 to 12 hours, so that the infused water becomes a liquid medium that carries more nutrients than ordinary water and will be more easily absorbed by cells and distributed throughout the body (Sidauruk, 2018 ). In several studies, it is stated that dates can increase hemoglobin levels in the blood. Where dates contain iron, vitamin A, vitamin C, protein to form red blood cells. With the method, Infused Water the date palm water becomes alkaline so that it can accelerate the absorption process in the body. The purpose of this study was to determine the effectiveness of dates infused water provision to increase hemoglobin levels of midwifery adolescent girls at Medan Health Polytechnic in 2020. This research was quasi-experimental study using the One Group Pretest-Posttest Without Control Design approach. The sample in this study were 20 respondents of midwifery adolescent girls from Medan Health Polytechnic, using the technique of purposive sampling. The statistical test used wa the Wilcoxon Signed Rank Test because the data was not normal. The results of the Wilcoxon Signed Rank Test obtained the value of P-Value = 0.001.

Background: To improve rates of human immunodeficiency virus (HIV) case detection and treatment, the Nigerian Ministry of Defense Health Implementation Program and the US Army Medical Research Directorate-Africa/Nigeria introduced a HIV standard of care (SOC) package. Given the integration of tuberculosis (TB) and HIV programs and evolving policies, we evaluated the impact of this strategy on TB program indicators.Methods: Routine, de-identified program data from 27 Nigerian military hospitals were analyzed. Using Wilcoxon signed-rank test, bivariate analyses were performed to compare data from 12 months before and after implementation of the SOC package.Results: Our data showed improvements post-implementation as follows: the number of individuals receiving antiretroviral therapy (ART) screened for TB increased from 14 530 to 29 467 (P < 0.001); the number of individuals with presumptive TB identified increased from 803 to 1800 (P < 0.001); the number of ART clients bacteriologically tested for TB increased from 746 to 1717 (P < 0.001); and the number of ART clients treated for TB increased from 152 to 282 (P < 0.001). Newly registered or relapsed TB cases increased from 436 to 906 (P < 0.001), the number of TB cases with known HIV status increased from 437 to 837 (P < 0.001), the number of TB-HIV co-infected cases increased from 182 to 301 (P = 0.006), and the number of TB-HIV co-infected clients who started ART increased from 101 to 176 (P = 0.003).Conclusion: The implementation of the updated HIV SOC package led to the improvement in key TB diagnosis and treatment indicators. When emulated, this could help improve the performance of other TB programs in countries other than Nigeria.
