Cassava Identification Model Based on Color for Mocaf Flour Using Digital ImageAbstractThis study aims to produce a model to identify the quality of cassava-based on color as an ingredient for making mocaf flour based on digital images. The procedure includes preprocessing and feature extraction among other steps of digital image processing. Preprocessing includes cropping, resizing, and grayscaling, while feature extraction includes threshold segmentation and binaryization. The data are 188 cassava images consisting of 72 training data images and 46 test data. The result of the study is an identification model based on the following two things: a) utilizing feature extraction that uses threshold segmentation with a threshold value of 170 and binaryization with a threshold value of 75; and b) determining of the quality of cassava is carried out based on the ratio of the area of white pixels produced by threshold segmentation to the area of white pixels produced by binaryization. If 65% or more of the pixels in the image are white, the cassava has a good quality. The resulting model provides an accuracy of 94% for 72 training data and 95% for 46 test data.
Gender Bias When Using Artificial Intelligence to Assess Anorexia Nervosa on Social Media: Data-Driven Study
Authors: Solans Noguero David , Ramírez-Cifuentes Diana , Ríssola Esteban Andrés , Freire Ana 
Published: June 2023

Background
Social media sites are becoming an increasingly important source of information about mental health disorders. Among them, eating disorders are complex psychological problems that involve unhealthy eating habits. In particular, there is evidence showing that signs and symptoms of anorexia nervosa can be traced in social media platforms. Knowing that input data biases tend to be amplified by artificial intelligence algorithms and, in particular, machine learning, these methods should be revised to mitigate biased discrimination in such important domains.

Objective
The main goal of this study was to detect and analyze the performance disparities across genders in algorithms trained for the detection of anorexia nervosa on social media posts. We used a collection of automated predictors trained on a data set in Spanish containing cases of 177 users that showed signs of anorexia (471,262 tweets) and 326 control cases (910,967 tweets).

Methods
We first inspected the predictive performance differences between the algorithms for male and female users. Once biases were detected, we applied a feature-level bias characterization to evaluate the source of such biases and performed a comparative analysis of such features and those that are relevant for clinicians. Finally, we showcased different bias mitigation strategies to develop fairer automated classifiers, particularly for risk assessment in sensitive domains.

Results
Our results revealed concerning predictive performance differences, with substantially higher false negative rates (FNRs) for female samples (FNR=0.082) compared with male samples (FNR=0.005). The findings show that biological processes and suicide risk factors were relevant for classifying positive male cases, whereas age, emotions, and personal concerns were more relevant for female cases. We also proposed techniques for bias mitigation, and we could see that, even though disparities can be mitigated, they cannot be eliminated.

Conclusions
We concluded that more attention should be paid to the assessment of biases in automated methods dedicated to the detection of mental health issues. This is particularly relevant before the deployment of systems that are thought to assist clinicians, especially considering that the outputs of such systems can have an impact on the diagnosis of people at risk.

Analisis Fatwa MUI Tentang Tes Swab Untuk Mendeteksi Covid-19 Saat Berpuasa Perspektif Pandangan Ulama dan Relevansinya
Authors: Zulyenni Yola 
Published: June 2023

Circular Letter of the Covid-19 Handling Task Force Number 11 of 2022 concerning Provisions for the Travel of Domestic Persons During the Covid-19 Pandemic Period is the basis for revoking the obligation for Rapid antigen tests for people who have received full doses of vaccines and booster vaccines, but are required to comply with health protocols. People who receive the first dose of the vaccine and who have not received the vaccine for reasons of special health conditions must show negative results from the RT-PCR test or rapid antigen test. This regulation also applies to travellers who are fasting. One prohibition that must be avoided while fasting is putting something into the body. In response, the Indonesian Ulama Council issued fatwa number 23 of 2021 concerning the Swab Test to Detect Covid-19 While Fasting, which states that the swab test does not break fast. So it is necessary to study how the views of the Ulama on this fatwa and its relevance to the situation when this fatwa was decided. This study uses the method of literature review. The approach used is the ushul fiqh approach, and the theory used is istihsan. The primary legal material used is the MUI Fatwa Number 23 of 2021, and the secondary legal material used is books and journal articles. The purpose of this study was to find out the views of the Ulama on the results of the MUI's Ijtihad in establishing Fatwa Number 23 of 2021 so that there is no doubt when carrying out a swab test while fasting and whether this MUI fatwa is relevant to the situation at the time this fatwa was decided. The study's results show that Ulama's views on the results of the MUI's Ijtihad in establishing Fatwa Number 23 of 2021 are divided into two opinions. Most contemporary scholars say that the law on swab testing during fasting does not break the fast. According to the classical ulama, the Hambali and Shafi'i ulama declared it null and void. The Maliki school of thought believes there is a gap for the swab not to break the fast because it is a dry and solid object that does not reach the stomach. The Hanafi school believes that the swab is not invalidated because it does not enter the body perfectly. MUI's decision-making in establishing Fatwa No. 23 of 2021 is considered relevant to the situation when this fatwa was issued. This fatwa is an effort to emphasize the spread of Covid-19.

Abstract

OBJECTIVE
While the clinical utility of next-generation DNA sequencing (NGS) as a diagnostic tool for infections in humans and traditional pets has been demonstrated, there is a lack of data regarding its utility for exotic animals. For exotic patients, traditional culturing is especially challenging for anaerobic and fungal pathogens. Therefore, diagnosis often relies on PCR, which provides a high degree of sensitivity and specificity, although it targets only a predetermined, finite pathogen panel. NGS provides the same benefits as PCR, while also offering de novo identification and quantification of all bacteria and fungi present in a clinical sample, including novel pathogen discovery.

PROCEDURES
Clinical samples from 78 exotic animal patients were collected simultaneously for conventional culture testing and NGS analysis. Results provided by each laboratory were compared for the presence and absence of bacterial and fungal pathogens and commensals.

RESULTS
Results showed large bacterial and fungal species diversity in the study cohort and a lack of sensitivity of microbial culture testing. Culture failed to grow 15% of putative bacterial and 81% of putative fungal pathogens that were identified by NGS. The probability of a “no growth” diagnosis was 14% higher for bacteria and 49% higher for fungi with culture versus NGS testing if fungal culture was conducted.

CLINICAL RELEVANCE
Culture testing failed to diagnose a substantial number of both bacterial and fungal pathogens, which were detected by NGS. This highlights the limitations of traditional culture-based testing and displays the clinically advanced utility of NGS-based diagnostics in exotic animal medicine.

Penilaian Hasil Dipstik Urine (Nitrit Dan Leukosit Esterase) Sebagai Prediktor Bakteriuria
Authors: Parwati Putu Ayu , Cahyani Anak Agung Ayu Eka 
Published: June 2023

Bacteriuria is the leading indicator of Urinary Tract Infection (UTI), which is detected through urine culture examination. Significant bacteriuria indicates the growth of microorganisms as much as ≥ 100,000 cfu/ml in urine culture. There are drawbacks to this examination that requires a screening test with a short time and lower cost. This study aimed to determine differences in the results of nitrite and leukocyte esterase examination using a urine dipstick with urine culture as a predictor of bacteriuria. The type of research used is analytic with an experimental approach. The sample used in this study was ten samples of urine. Based on the bivariate analysis results, the p-value was 0.541, which means that there was no difference in the results of leukocyte esterase and urine culture. This indicates the presence of leukocytes in the urine can be an indication of bacteriuria. The results for the nitrite examination obtained a p-value of 0.000, which means there is a difference between the results of the nitrite examination and the results of the urine culture. This shows that the presence of nitrites in the urine cannot indicate of bacteriuria. However the data on the sensitivity and specificity of dipstick examination are still low for leukocyte esterase and urine nitrite tests. However, urine dipstick examination to detect bacteriuria and UTI is still an option for faster screening. Keywords : leukocyte esterase, nitrites, urine culture

Published: June 2023

Obesity is described as the accumulation of excess body fat. Several health issues are caused by excess fat, including cancer, type 2 diabetes, and cardiovascular disease. Additionally, obesity rates among schoolchildren and young adults are rising globally, putting young people at risk of chronic diseases. Genetics, epigenetic modification, epigenomics, and environmental factors influence inheritance patterns significantly. This systematic study aimed to classify and investigate the polymorphisms of novel candidate obesity genes. Several genes have been suggested, includingat mass and obesity-associated gene (FTO), leptin gene (LEP), leptin receptor gene (LEPR), peroxisome proliferatoractivated receptor gamma gene (PPARG), melanocortin 4 receptor (MC4R), insulin-induced gene 2 (INSIG2), proprotein convertase subtilisin/kexin type 1 (PCSK1), adrenoceptor beta 2 (ADRB2), and uncoupling protein 2 (UCP2). The study’s literature review identified genes in scientific papers published in databases such as Web of Science, PubMed, Google Scholar, Embase, and others over the past three decades. There is evidence that genetic variations contribute to childhood obesity, adolescent obesity, and young adult obesity. Identifying functional differences and further defining the implicated molecularly and physiologically involved genes andpathways in efficient therapeutic approaches in fighting. Technological advances have recently demonstrated that genetic changes and mutations can be used as biological markers, risk indicators, and therapeutic targets.
