Authors: Kurniawan Indra Fajar , Maulana Ahmad Rizky Ananda , Naufal Muhammad Faris , Rezeki Ingrid Multi
Published: December 2024

Mini Hydro Power Plants (MHPs) utilize the potential of water to generate electrical energy. However, construction on clay soils that have the potential to expand and contract can affect the stability of the structure. This study aims to evaluate the potential for soil development in the Cileunca MHP. The methods used to determine soil development potential include Chen (1988), Skempton (1953), and Seeds (1962) methods. Mineral identification was conducted through X-Ray Diffraction (XRD) testing of soil samples taken by the handboring method. The results of the analysis showed that the Skempton method showed 67% of the samples had activity values > 0.75 (“high” category). The Chen method indicated 60% of the samples had a plasticity index (PI) > 35% (“very high” category). The Seeds method indicated 73% of the samples had a development potential > 25% (very high category). XRD testing indicated the dominant mineral was dehydrated Halloysite (Al2Si5(OH)4). The soil at the Cileunca MHP site has a high development potential that can damage building foundations. Foundation stability is strongly influenced by expansive soil properties, so soil stabilization treatment is needed to prevent structural damage. This study concludes that the soil at the Cileunca MHP site has a high development potential, which can cause structural problems. Therefore, soil stabilization treatment is highly recommended to ensure the stability of the building foundation

Published: December 2024

Background: Genu varum, a common knee alignment issue, may negatively affect physical performance in athletes, particularly in sports requiring balance, agility, and strength, such as football. Objectives: This study aimed to examine the impact of genu varum on dynamic balance, core muscle endurance, and various athletic performance metrics in male football players. Methods: This descriptive and correlational study included 42 young football players, 21 with genu varum and 21 without. All participants trained at least three times per week and were screened for genu varum using a caliper. After applying inclusion and exclusion criteria, the participants completed tests to assess dynamic balance, core muscle endurance, lower body strength, agility, and speed. Key performance evaluations included the Sargent Jump test, a 9x4 meter agility test, and a 36-meter sprint. Independent t-tests were conducted to compare the two groups. Statistical analyses were performed using SPSS version 22, with a significance level set at 0.05. Results: Significant differences were found between the two groups. Players with genu varum showed reduced dynamic balance in all directions (anterior: P = 0.001, posterior-medial: P = 0.002, posterior-lateral: P = 0.004), lower body strength (P = 0.001), agility (P = 0.02), abdominal muscle endurance (P = 0.004), and sprint speed (P = 0.003) compared to players without genu varum. Conclusions: The findings indicate that genu varum adversely affects essential athletic performance components, including balance, strength, agility, and speed, in young football players. These deficits may increase the risk of injury and impede long-term athletic development.

Inference on modified Weibull type distribution and its application to Competing risks data using MCMC
Authors: Rangoli A.M. , Talawar A.S.
Published: December 2024

For lifetime data analysis, failure time analysis, or survival analysis, the Weibull distribution is commonly used due to its various hazard functions, which can be increasing, decreasing, or constant. We have extended the traditional twoparameter Weibull distribution to accommodate hazard functions that are increasing, decreasing, constant and bathtubshaped. Utilizing a competing risks approach, we applied this modified Weibull distribution to both simulated data and an observed mice dataset. Our findings indicate that the modified Weibull distribution provides a better fit to the mice dataset compared to the traditional Weibull distribution. We estimated the parameters of the modified Weibull distribution using Maximum likelihood estimation (MLE) and Bayesian methods. For MLE, we employed the Newton-Raphson numerical method, while for the Bayesian approach, we used the Metropolis-Hastings algorithm, an MCMC method. Additionally, we plotted hazard curves for both the simulated and mice datasets. The Kaplan-Meier survival curves were plotted along with the survival curve of the modified Weibull distribution..

Evaluation and Selection of Supplier in A Healthcare Supply Chain using Analytic Hierarchy Process under Fuzzy Environment
Authors: Bhosale Trupti S. , Umap Hemant P.
Published: December 2024

The aim of the supplier selection process is to reduce purchasing risks, boost customer profitability, and cultivate enduring, close relationships between suppliers and buyers. This process stands as a pivotal component of supply chain management (SCM), making supplier selection a critical concern for establishing an effective supply chain system. In this instance, a case study has been presented for supplier selection employing Analytic Hierarchy Process (AHP) in conjunction with the Multi-Criteria Decision Making (MCDM) technique. We have explained it using fuzzy data. It not only contributed on utility of fuzzy AHP methodology, but also provided comprehensive literature review of MCDM problems. Furthermore, by outlining the steps of fuzzy AHP in a straightforward numerical manner, this study can serve as a guide for implementing the methodology in other (MCDM) problems. In this study, we evaluate four suppliers using fuzzy AHP. This method can be used when one has to select one particular supplier from a number of suppliers in a short time span. It will be also helpful to the Pharmacists to select the best supplier who can fulfil all their needs. Despite the abundance of studies on supplier selection, there has been relatively less investigation into the evaluation and selection of suppliers using specific measures tailored to the healthcare sector. To bridge this gap, this research puts forth a guideline for selecting suppliers of baby hygiene products.. KEYWORDS :Supplier, AHP, Fuzzy, Evaluation, Supply chain management (SCM).

Published: December 2024

Land use system has a great impact on soil properties. The effect of land use on soil chemical, microbiological properties and soil moisture of salt-affected soils was investigated in India. Soil samples were collected from Solonetz soils under different land uses such as arable land (SnA), bare land (SnB) and pasture land (SnP). Results of the study showed that the chemical and microbiological properties of all three sites were statistically different from each other. The principal components (PC1 and PC2) retained for the analysis accounted for 86.26% of the total variance. The values of microbiological properties were the highest in SnA, intermediate in SnP and the lowest in case of SnB. Discriminant analysis of microbiological properties showed that 93.64% of variation and can be determined by MBC. The primary objective of our study was to ascertain how farmers' perceptions and decisions regarding land use systems, which are based on their experiences rather than laboratory results, align with soil physical, chemical and microbiological properties, and how they contribute to preserving soil quality. Overall, it was concluded that arable land (SnA) had more favorable chemical properties and it has been microbiologically more active in investigated salt affected (Solonetz) soils. Moreover, soil conservation and amelioration practices are suggested in bare land and pasture land to prevent further degradation and to improve the soil quality of the investigated salt affected areas. Also, it is important to educate and transfer knowledge to the farmers about the consequences of soil degradation and advocate good soil management practices (gypsum application, nutrient management, crop cover, tillage etc.)..

Published: December 2024

Manufacturers today prioritize increasing output quality while reducing per-unit costs to remain competitive. Statistical Process Control (SPC) is a useful tool for boosting quality and output. However, decision-makers in industries face difficulties in cost and quality control due to uncertainty in data. Fuzziness can be applied to uncertain data to manage the economic design of a control chart, allowing for better control over the control chart's economic design. This study seeks to enhance the economic design of X control charts by using fuzzy set theory, specifically utilizing triangular fuzzy numbers for cost parameters and the signed distance approach for defuzzification. The objective is to enhance the adaptability of these charts in unpredictable situations. The proposed model enables the incorporation of cost parameters inside a fuzzy framework, with the objective of minimizing the control chart while adhering to the permissible limit. The applicability and improved accuracy of the model in optimizing control chart parameters for a glass bottle production process are exemplified by an effective illustration. This study highlights the need of integrating fuzzy logic into SPC. It suggests a technique that improves the cost-effectiveness and operational effectiveness of control charts in situations when data is uncertain and imprecise. .

Published: December 2024

Confounding is a major problem in epidemiological research during the analysis of epidemiological data. To identify the confounder in the relationship between disease and risk factor is of prime importance because confounders distorts the actual relationship of risk factor on the disease. Due to the influence of confounder, on the factor disease relationship, the study may not provide the representative results of the association of the study sample. In the present study an attempt has been made to identify different confounders in the risk factor diabetes on disease hypertension among women under reproductive age groups. To achieve the objectives of the study data from the fourth round of National Family Health Survey (2015-2016) are used. To search the different confounders which may influence the relationship between hypertension and diabetics, stratum specific odds ratios and Mantel-Haensel common odd ratios are calculated. It has been found that, the women who are Diabetic associated with an increased risk of hypertension with the odds ratio of 2.27 (95% CI: 2.21-2.32).Risk factors such as age, body mass index (BMI), smoking are found as a confounders..

Sampling frames play an important role in survey research as they lay the foundation on the basis of which representative sample drawn from a target population. However, in practice, sampling frames are often incomplete, meaning that they do not fully capture the complete population of interest. In such cases, as a consequence of the incompleteness in sampling frame, the sample drawn does not provide a good representation of the population and hence, the results infer to vague and misleading conclusions. The present study is an attempt to somehow uplift the efficacy of the estimator of population mean by taking into consideration, the additional information gathered from the units currently excluded in the existing sampling frame along with mean square error of the proposed estimator. Optimum sample sizes are also obtained using suitable cost function under Neyman scheme. To compare the proposed estimator with the traditional ones, a simulation study has been done..

It is challenging to forecast crude oil prices. Given that the international crude oil price is time-varying and nonlinear, suggest a new mixed method for oil price forecasting. First, the traditional time series technique ARIMA method for predictions is incorporated. Then, The time-varying and nonlinear components of crude oil prices are forecasted using machine learning approaches such as boosted trees, SVM, ANN, LSTM, bagged trees and linear regression, etc. The ultimate predicted outcomes of crude oil prices are then calculated by adding the predicted prices of each component. The results showed that the new proposed hybrid method was capable of a high degree of oil price prediction based on its exceptional ability to adapt sample selection, data frequencies and structural breaks. In addition, the comparisons show that the new method proves to be more accurate than these well-known methods for crude oil price forecasts. The WTI daily data from 1986 to 2018 has been utilised for forecasting of crude oil trend for 2018 in next 50 days. Forecasts were made using the time series forecasting approach with the ARIMA model and the machine learning approach. Validation metrics have been used to evaluate the performance of these models and it was noted that they performed well. The effects of prediction methods on crude oil data are discussed with the help of graphs for the predictions for next 50 days, actual and predicted plots, model performance plot, and validation performance plot for all the methods. Compared to the previous published work, the accuracy of the problem has been verified by comparing it to the quantitative outputs exhibited in this, and the agreement between the results is excellent, which has led to confidence in the quantitative results projected in this study..

This study aims to analyze the effect of perceived social support and gratitude on teacher subjective well-being of honorary teachers in secondary schools in Madrid during the pandemic. Using a quantitative approach with an ex post facto design, this study involved 202 honorary teachers selected through purposive sampling. The research instruments included the Gratitude Questionnaire, the Revised-Multidimensional Scale of Perceived Social Support (R-MSPSS), and the Teacher Subjective Well-Being Questionnaire (TSWQ). The results of the analysis using Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM) showed that perceived social support and gratitude played a significant and positive role in teacher subjective well-being. The higher the perceived social support and gratitude values, the higher the level of teacher subjective well-being. The results of this study have theoretical implications for the development of educational psychology and positive psychology, as well as providing practical recommendations for teachers and the government to improve teacher well-being through curriculum adaptation and other supporting strategies.
