Infant mortality remains a public health problem in Aceh Province, Indonesia. Health services during pregnancy are an essential factor in reducing infant mortality. Studies examining factors such as maternal and child health services that have implications for infant mortality in Aceh province are still scarce. Therefore, this study aims to examine the correlation between maternal and child health services variables such as Blood-Supplementing Tablets (TTD), Coverage of the First Visit of Pregnant Women (K1), Coverage of the First Visit of Pregnant Women (K4), and management of Obstetric Complications to live births and to map the maternal and child health services obtained during pregnancy. A cross-sectional study was used as the research study. This study used descriptive statistics, such as measures of data centering and data dispersion. In this work, inferential statistical analysis was conducted using the Shapiro-Wilk test, Spearman test, and fuzzy c-means. The result of the Shapiro Wilk test stated that the live birth rate variable and all Maternal and Child Healthcare Services variables were not normally distributed (p-value < 0.05), all Maternal and Child Healthcare Services variables were positively correlated to live birth rate based on the Spearman test (p-value < 0.05). Based on the Silhouette Index with 0.555, the formation of 3 clusters is the optimal cluster. The clustering is based on the Maternal and Child Healthcare Services that have been provided, where the first, second, and third clusters consist of five districts/city, eight districts/city, and ten districts/city, respectively, as a result of Fuzzy C-Means Clustering.
婴儿死亡率仍然是印度尼西亚亚齐省的一个公共卫生问题。怀孕期间的保健服务是降低婴儿死亡率的一个重要因素。审查对亚齐省婴儿死亡率有影响的妇幼保健服务等因素的研究仍然很少。因此,本研究旨在研究妇幼保健服务变量之间的相关性,如补血片(TTD)、孕妇首次就诊的覆盖率(K1)、孕妇首次就诊的覆盖率(K4)和活产产科并发症的管理,并绘制怀孕期间获得的妇幼保健服务。本研究采用横断面研究。本研究采用描述性统计,如数据中心和数据分散的措施。本研究采用Shapiro-Wilk检验、Spearman检验和模糊c-means进行推理统计分析。Shapiro Wilk检验的结果表明,活产率变量和所有妇幼保健服务变量都不是正态分布的(p值<0.05),根据Spearman检验,所有妇幼保健服务变量与活产率呈正相关(p值<0.05)。基于剪影指数0.555,形成3个集群为最优集群。聚类基于已提供的妇幼保健服务,其中第一、第二和第三聚类分别由5个区/市、8个区/市和10个区/市组成,这是模糊c均值聚类的结果。

Leukemia is a blood cancer in which blood cells become malignant and uncontrolled. It can cause damage to the function of the body's organs. Several machine learning methods have been used to automatically detect biomedical images, including blood cell images. In this study, we utilized a hybrid machine learning method, called a hybrid Convolutional Neural Network-eXtreme Gradient Boosting (CNN-XGBoost) method to detect leukemia in blood cells. The hybrid method combines two machine learning methods. We use CNN as the basic classifier and XGBoost as the main classification method. The aim of this methodology was to assess whether incorporating the basic classification method would lead to an enhancement in the performance of the main classification model. The experimental findings demonstrated that the utilization of XGBoost as the main classifier led to a marginal increase in accuracy, elevating it from 85.32% to 85.43% compared to the basic CNN classification. This research highlights the potential of hybrid machine learning approaches in biomedical image analysis and their role in advancing the early diagnosis of leukemia and potentially other medical conditions.
白血病是一种血癌,患者的血细胞变得恶性且无法控制。它会对身体器官的功能造成损害。几种机器学习方法已被用于自动检测生物医学图像,包括血细胞图像。在这项研究中,我们使用了一种混合机器学习方法,称为混合卷积神经网络-极端梯度增强(CNN-XGBoost)方法来检测血细胞中的白血病。混合方法结合了两种机器学习方法。我们使用CNN作为基本分类器,XGBoost作为主要分类方法。该方法的目的是评估纳入基本分类方法是否会提高主要分类模型的性能。实验结果表明,使用XGBoost作为主分类器,与基本的CNN分类相比,准确率从85.32%提高到85.43%,略有提高。这项研究强调了混合机器学习方法在生物医学图像分析中的潜力,以及它们在促进白血病和其他潜在医疗条件的早期诊断方面的作用。

This study aims to evaluate the implementation and effectiveness of the Adaptive Neuro-Fuzzy Inference System (ANFIS) based Quantitative Structure Retention Relationship (QSRR) to predict the Kovats retention index of compounds in gas chromatography. The model was trained using 340 essential oil compounds and their molecular descriptors. The evaluation of the ANFIS models revealed promising results, achieving an R2 of 0.974, an RMSE of 48.12, and an MAPE of 3.3% on the testing set. These findings highlight the ANFIS approach as remarkably accurate in its predictive capacity for determining the Kovats retention index in the context of gas chromatography. This study provides valuable perspectives on the efficiency of retention index prediction through ANFIS-based QSRR methods and the potential practicality in compound analysis and chromatographic optimization.

Diabetes is a chronic condition characterized by elevated blood glucose levels which leads to organ dysfunction and an increased risk of premature death. The global prevalence of diabetes has been rising, necessitating an accurate and timely diagnosis to achieve the most effective management. Recent advancements in the field of machine learning have opened new possibilities for improving diabetes detection and management. In this study, we propose a fine-tuned XGBoost model for diabetes detection. We use the Pima Indian Diabetes dataset and employ a random search for hyperparameter tuning. The fine-tuned XGBoost model is compared with six other popular machine learning models and achieves the highest performance in accuracy, precision, sensitivity, and F1-score. This study demonstrates the potential of the fine-tuned XGBoost model as a robust and efficient tool for diabetes detection. The insights of this study advance medical diagnostics for efficient and personalized management of diabetes.
糖尿病是一种慢性疾病,其特征是血糖水平升高,导致器官功能障碍和过早死亡的风险增加。糖尿病的全球患病率一直在上升,需要准确和及时的诊断,以实现最有效的管理。机器学习领域的最新进展为改善糖尿病的检测和管理开辟了新的可能性。在这项研究中,我们提出了一个微调的XGBoost糖尿病检测模型。我们使用皮马印第安糖尿病数据集,并采用随机搜索超参数调优。经过微调的XGBoost模型与其他六种流行的机器学习模型进行了比较,在准确性、精密度、灵敏度和f1分数方面达到了最高的性能。这项研究证明了微调后的XGBoost模型作为一种强大而有效的糖尿病检测工具的潜力。这项研究的见解促进了医学诊断对糖尿病的有效和个性化管理。
