Authors: De Meyer Dimitri , Chantziaras Ilias , Amalraj Arthi , Maes Dominiek
Published: January 2024

Weaning is one of the most important stress events in the life of pigs, increasing the risk for health problems and reduced performance. The release of pheromones in pig stables can be considered an environmental enrichment and alleviate the negative effects of weaning stress in nursery pigs. The present study investigated the effect of synthetic pheromones on the performance of nursery pigs. The effect of positive handling of sows in the farrowing house on the performance of the offspring in the nursery was also investigated. The study was performed in a commercial pig farm and included 24 batches of weaned piglets (216 piglets per batch). Half of the batches originated from sows exposed to positive handling. This implied that music was played from 6.00 a.m. to 6.00 p.m. from the moment the sows entered the farrowing house until weaning and that they were subjected to backscratching from the day they entered the farrowing unit the day of farrowing. During the nursery period, half of the batches were treated, and half served as controls. Piglets of treated groups were exposed to a synthetic analog of the maternal pig appeasing pheromone (PAP) (SecurePig®, Signs, Avignon, France). The product consisted of a gel block from which the pheromones were slowly released into the room. Different performance parameters were measured during the nursery period. Neither the sow treatment nor the treatment with pheromones significantly influenced the performance of the piglets during the nursery period (p > 0.05). The median values (95% confidence interval) of average daily gain, namely 318 (282–338) vs. 305 (272–322) g/day, feed conversion ratio, namely 1.64 (1.51–1.71) vs. 1.70 (1.57–1.75), and number of antimicrobial treatment days, namely 16.9 (9.6–25.0) vs. 17.3 (9.5–25.0) days, were numerically better in the nursery pigs exposed to the pheromones compared to the control groups. Mortality however was numerically higher in the treated groups, namely 4.4 (2.8–6.8) vs. 3.2 (0.9–4.2)%. Under the conditions of the present production system, pigs exposed to the pheromone treatment during the nursery did not show a significant performance increase.
Spatiotemporal Variation and Long-Range Correlation of Groundwater Levels in Odessa, Ukraine
Authors: Melkonyan Dzhema , Sugathan Sherin
Published: December 2023

Increasing groundwater levels (GWLs) may become one of the most serious issues for the city of Odessa, Ukraine. This study investigated the spatial distribution characteristics and multifractal scaling behaviour of the groundwater-level/-depth fluctuations for a Quaternary aquifer in the city of Odessa using a geostatistical approach and multifractal detrended fluctuation analysis (MF-DFA). These two methods were applied to monthly GWL fluctuation time series from 1970 to 2020 to monitor 72 hydrogeological wells situated in different parts of the city of Odessa. The spatial distribution of the GWLs revealed an overall trend of decline and recovery from 1970 to 2020 in the study area, except for most of the southern region, where a persistent recovery of the groundwater depth was observed. The MF-DFA results suggest that the dynamics of the GWL fluctuations have multifractal characteristics in the Odessa area. In addition, both long-range correlations and fat-tail probability distribution contribute to the multifractality. However, long-range correlations among the fluctuations made a major contribution to the observed multifractality of the GWL fluctuation time series. The generalised Hurst exponents show a wide range of change (0.20 < h(q) < 2.85), indicating the sensitivity of the GWL fluctuations to changes in small-scale factors and large-scale factors. Regarding the long-range correlations of the GWL depths, the Hurst exponents (q = 2) demonstrated the positive persistence of groundwater-depth recovery in the southern region and the persistence of groundwater-depth variation in the other regions of the study area. The dynamic changes in the GWL depths in the Odessa area may be influenced by both natural and anthropogenic factors.

Published: December 2023

The construction of large dams in the upper tributary basin of the Chao Phraya River (CPR) has been linked to a significant decrease in sediment load in the CPR system, estimated between 75–85%. This study, utilizing historical and recent river flow and sediment data from 1922 to 2019, examines the impact of three major dams constructed in the Nan River basin (the Sirikit, Naresuan, and Khwae Noi dams) on river runoff and sediment loads in the CPR. The investigation employed the Mann–Kendall (MK) test and the double mass curve (DMC) for analysis. Findings indicate that the Nan River is a major contributor to the CPR, accounting for around 40% of the runoff and 57% of the total sediment load (TSL). The Naresuan diversion dam’s water regulation was found to significantly reduce annual runoff and TSL downstream of the dam. Despite an initial increase in sediment load at the CPR headwater (C.2) post the construction of the Sirikit dam, attributed to expanded irrigation downstream and channel improvements in the lower Nan River, the operation of the three dams eventually led to a 31% reduction in sediment load at C.2 compared to pre-construction levels.
Development and Deployment of a Virtual Water Gauge System Utilizing the ResNet-50 Convolutional Neural Network for Real-Time River Water Level Monitoring: A Case Study of the Keelung River in Taiwan
Authors: Chen Jui-Fa , Liao Yu-Ting , Wang Po-Chun
Published: December 2023

Climate change has exacerbated severe rainfall events, leading to rapid and unpredictable fluctuations in river water levels. This environment necessitates the development of real-time, automated systems for water level detection. Due to degradation, traditional methods relying on physical river gauges are becoming progressively unreliable. This paper presents an innovative methodology that leverages ResNet-50, a Convolutional Neural Network (CNN) model, to identify distinct water level features in Closed-Circuit Television (CCTV) river imagery of the Chengmei Bridge on the Keelung River in Neihu District, Taiwan, under various weather conditions. This methodology creates a virtual water gauge system for the precise and timely detection of water levels, thereby eliminating the need for dependable physical gauges. Our study utilized image data from 1 March 2022 to 28 February 2023. This river, crucial to the ecosystems and economies of numerous cities, could instigate a range of consequences due to rapid increases in water levels. The proposed system integrates grid-based methods with infrastructure like CCTV cameras and Raspberry Pi devices for data processing. This integration facilitates real-time water level monitoring, even without physical gauges, thus reducing deployment costs. Preliminary results indicate an accuracy range of 83.6% to 96%, with clear days providing the highest accuracy and heavy rainfall the lowest. Future work will refine the model to boost accuracy during rainy conditions. This research introduces a promising real-time river water level monitoring solution, significantly contributing to flood control and disaster management strategies.

Published: December 2023

Purified red phosphorus (RP) can be used as an adsorbent. However, the adsorption mechanism and reuse ability of purified RP have not been reported. This study utilized X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy techniques (a statistical physics model and the standard molar free energy of formation) to investigate the adsorption mechanism of methylene blue (MB) by purified RP. Purification did not change commercial RP structure according to X-ray diffraction. The results showed that the adsorption process only included physical adsorption according to Fourier transform infrared spectroscopy and UV–vis diffuse reflection absorption spectra. The specific areas of commercial RP and purified RP were 0.02 cm3/g and 5.27 cm3/g, respectively. Thus, purified RP has a higher adsorption capacity compared with commercial RP. A statistical physics model showed that, as the temperature increased from 288 to 308 K, the qe, Dm and qsat of purified RP for MB increased from 179.87, 0.824 and 0.824 to 303.26 mg/g, 1.497 mol/kg and 1.497 mol/kg, respectively. The fitted values of ΔrSmθ, ΔrHmθ and ΔrGmθ were 104.38 J·mol−1·K−1, −2.7 × 103 J·mol−1 and negative, respectively. Thus, according to adsorption energy, the adsorption of MB by purified RP was a spontaneous process, which was mainly driven by entropy increasing. Compared with neutral dye, the purified RP had higher adsorption ability for the cationic dye and anionic dye. As the purified RP dose increased from 30 to 150 mg, the adsorption capacity of purified RP increased. However, as the MB concentration and pH increased, the adsorption capacity of purified RP decreased. The purified RP had excellent reuse ability and high temperature desorption can be applied to obtain its reuse ability.
Advancements in Electric Vehicle PCB Inspection: Application of Multi-Scale CBAM, Partial Convolution, and NWD Loss in YOLOv5
Authors: Xu Hanlin , Wang Li , Chen Feng
Published: January 2024

In the rapidly evolving electric vehicle industry, the reliability of electronic systems is critical to ensuring vehicle safety and performance. Printed circuit boards (PCBs), serving as a cornerstone in these systems, necessitate efficient and accurate surface defect detection. Traditional PCB surface defect detection methods, like basic image processing and manual inspection, are inefficient and error-prone, especially for complex, minute, or irregular defects. Addressing this issue, this study introduces a technology based on the YOLOv5 network structure. By integrating the Convolutional Block Attention Module (CBAM), the model’s capability in recognizing intricate and small defects is enhanced. Further, partial convolution (PConv) replaces traditional convolution for more effective spatial feature extraction and reduced redundant computation. In the network’s final stage, multi-scale defect detection is implemented. Additionally, the normalized Wasserstein distance (NWD) loss function is introduced, considering relationships between different categories, thereby effectively solving class imbalance and multi-scale defect detection issues. Training and validation on a public PCB dataset showed the model’s superior detection accuracy and reduced false detection rate compared to traditional methods. Real-time monitoring results confirm the model’s ability to accurately detect various types and sizes of PCB surface defects, satisfying the real-time detection needs of electric vehicle production lines and providing crucial technical support for electric vehicle reliability.

Published: January 2024

Urbanization in Indonesia resulted in population density in urban areas, which has the potential for economic growth, marked by increased population income followed by changes in consumption patterns that will cause environmental problems in urban areas. Seeing environmental issues that occur in urban areas, it is necessary to have a green city concept city planning as a sustainable city planning solution without damaging the environment. The measurement of green city achievement has yet to be carried out in Indonesia. This study aims to measure the Green City Index (GCI) in metropolitan districts/cities in Indonesia using Partial Least Squares-Structural Equation Modeling (PLS-SEM). It examines the GCI achievements in Indonesian metropolitan districts/cities. The GCI is formed by a socioeconomic dimension of two indicators and an environmental dimension of eleven indicators. Generally, the highest GCI achievements are in the Bogor District, with a score of 74.3 percent. Bangkalan District achieved the highest socioeconomic dimension index, and Bogor District completed the highest environmental dimension index. In addition, there is a significant and negative relationship between GCI and the Human Development Index (HDI) and economic growth. It is hoped that the government and the community can pay attention to the balance of the environment in their activities.

Authors: Syukrilla Wara Alfa , Andriyana Yudhie , Verhasselt Anneleen
Published: December 2023

We investigate the impact of the percentage of clean water access, the percentage of handwashing habits, and the toilet category factors on the upper quantile of toddlers’ diarrhea risks in Bandung City, Indonesia, using the Geographically Weighted Quantile Regression model on the 75th percentile. The breusch-Pagan test was used to detect spatial heterogeneity. The results show that the significance, strength, and direction of the relationship between diarrhea and its risk factors depend on the location. At the upper quantile, the Panyileukan district is predicted to have the highest diarrhea risk. In this district, all three predictors significantly affect the toddlers’ diarrhea risk, with the variable of the percentage of houses practicing hand washing habits observed to reduce diarrhea risk the most. In conclusion, clean water access, handwashing habits, and toilet category are the potential risk factors for high-risk childhood diarrhea. This method is powerful as it would allow the decision maker to handle the diarrhea problem aptly based on which predictor has a substantial effect at a specific district of interest. And it can be used to investigate the effect of various intervention strategies and effectively allocate the limited available resources according to the most important locations.

In general, spatial regression is used to model one of the spatial effects, namely spatial dependency or heterogeneity. For the effects of spatial dependencies, the models that have been used frequently follow Elhost's taxonomy, with the spatial dependencies being on the response, predictor, or error. Whereas for the effect of spatial heterogeneity generally use geographically weighted regression models (GWR) or if there are global predictors use mixed geographically weighted regression (MGWR). The data used in this study are cases of Human Immunodeficiency Virus (HIV) per 100,000 population as a response variable, and key populations, positive cases in pregnant women, tuberculosis patients, poverty rate, and unemployment rate as predictors. In the data used, there are spatial dependencies and heterogeneity. The MGWR-SAR is a model that can be used if the data has both spatial effects. This study aims to determine the factors influencing HIV cases in districts/cities in Indonesia using a spatial model. The results showed that the combined model of GWR and spatial autoregressive regression (SAR) was the best model. Key population explanatory variables have a global and significant influence. Other explanatory variables that have local influence are positive cases in pregnant women, tuberculosis patients, poverty rates, and unemployment rates.
Morphology-Tailored Dynamic State Transition in Active-Passive Colloidal Assemblies
Authors: Yu Nan , Shah Zameer H. , Yang Mingcheng , Gao Yongxiang
Published: January 2024

Mixtures of active self-propelled and passive colloidal particles promise rich assembly and dynamic states that are beyond reach via equilibrium routes. Yet, controllable transition between different dynamic states remains rare. Here, we reveal a plethora of dynamic behaviors emerging in assemblies of chemically propelled snowman-like active colloids and passive spherical particles as the particle shape, size, and composition are tuned. For example, assembles of one or more active colloids with one passive particle exhibit distinct translating or orbiting states while those composed of one active colloid with 2 passive particles display persistent “8”-like cyclic motion or hopping between circling states around one passive particle in the plane and around the waist of 2 passive ones out of the plane, controlled by the shape of the active colloid and the size of the passive particles, respectively. These morphology-tailored dynamic transitions are in excellent agreement with state diagrams predicted by mesoscale dynamics simulations. Our work discloses new dynamic states and corresponding transition strategies, which promise new applications of active systems such as micromachines with functions that are otherwise impossible.

Online vs Paper Examination in University EFL courses
Authors: Stevkovska Marija
Published: December 2023

Universities have long been struggling with academic dishonesty in both online and pen-and-paper examinations. Different authors have suggested various deterrents to decrease cheating during exams. The aim of this study is to investigate how the online environment affects academic dishonesty during online exams and to compare students’ behaviour during written and paper exams. The hypotheses tested is that there is a significant difference between mean values of the results achieved on pen-and-paper tests and online tests. The research adopted a cross-sectional study design. The Wilcoxon Signed Ranks Test confirmed the hypothesis as it showed that the scores on the online exam (mean rank = 35.9) were statistically higher than the ones on the pen-and-paper test (mean rank = 28.3), Z= -3.311, p=0.001 with a small effect size r = 0.29. This could be due to the test format and insufficient proctoring technology. Online cheating could be minimized by giving priority to formative assessment, by raising students’ awareness of the negative consequences of academic dishonesty, and implementing more sophisticated technologies to track students’ behavior during online exams. Additionally, multiple-choice questions should be replaced by open-ended questions. Finally, a speaking section could be added to online tests, which is to be passed successfully in order for students to receive a passing grade for the EFL course.

Se considera que este fenómeno es provocado por las temperaturas altas durante el crecimiento del fruto. El objetivo de la presente investigación fue ampliar el periodo de cosecha de la variedad Kent, la más cultivada en la región, con 48 % del área plantada. Se establecieron dos experimentos, en los municipios de Escuinapa en 2018 y en El Rosario en 2019, ambos en el estado de Sinaloa, México. Los tratamientos fueron poda manual y poda química con etefón (ácido 2-cloroetilfosfónico) a dosis de 1.0 y 1.2 mL L-1 en panículas de la primera floración durante antesis para provocar una segunda floración en yemas axilares, el testigo consistió en árboles sin poda. La poda manual retrasó la floración entre 40 y 42 d, y con la poda química el retraso de la floración fue de entre 45 y 47 d; el retraso en la cosecha fue de 33 y 31 d, respectivamente. Por cada panícula apical podada se formaron de 2.5 a 4.8 panículas axilares. En 2018 las podas manual y química de panículas apicales tuvieron menos frutos, pero de mayor tamaño que el testigo, lo que resultó en una producción más equilibrada entre tratamientos. En 2019 el testigo sin podar fue más productivo. Los frutos del testigo y de los árboles podados con etefón 1.2 mL L-1 tuvieron el mejor comportamiento en los indicadores de calidad firmeza, sólidos solubles totales (SST) y la relación SST/acidez (RSA). Se concluye que el desfase de la floración mediante poda manual o química con etefón de panículas de la primera floración puede ser una alternativa para el retraso de la cosecha en mango Kent con frutos de calidad.

Previous studies on the relationship between GHG emissions and financial performance presented two competing points of view: either reducing GHG emissions can cause firms to diverge from their corporate goals, or, reducing GHG emissions can raise firm value in line with the resource-based view theory. This study examines 105 non-financial industry in Indonesia that produce significant amounts of emissions GHG between 2019 and 2021, with a total of 315 data observations. This study analyzes the financial performance using ROA and firm value, and the performance of GHG emissions using two constructs: the quantity of emissions and disclosure of GHG emissions. The Global Initiative Report (GRI) guidelines are used to conduct content analysis on disclosure of GHG emission. This study shows that GHG emission performance is considered as a firm's competitive advantage, there is a positive relationship between GHG emission performance and firm value, financial constraints negatively impact the relationships between GHG emission performance, and COVID-19 had no impact on the relationship between emission performance and financial performance.

An interactive learning strategy was a method or technique the teacher used when presenting learning materials where the teacher became the main actor in creating an educative interactive situation. The objective of this study was to create interactive media for theme learning that focuses on the development of soft skills and to evaluate its quality and usefulness. This study used Borg and Gall's Research and Development (R&D) approach, with four parsimonious stages of development: analysis, design, development, and implementation. This research used observation and interview sheets as data collection methods. The assessment of the interactive media's validity, quality, and efficacy based on soft skills was conducted through instrument and product validation methods involving media specialists and reviews from instructors and students. The study showed that students and teachers rated interactive learning media based on soft skills in the high-quality category. In addition, soft skill-based learning media was considered effective in fulfilling the criteria for assessing teacher activity in learning media, namely in the very effective category. It was concluded that the soft skill-based interactive learning media developed in this study were valid, high quality, and effective, so they were suitable for use in Penggalang 4 public elementary schools. We recommend that schools implement interactive media based on soft skills so that students become active and critical learners. Future research can adapt our model to other educational levels or domains, such as employee business development.

In the era of the Industrial Revolution 4.0, learning mathematics puts more demands on students’ computational thinking skills. This research responds to this challenge by developing learning media assisted by iSpring Suite 9 and GeoGebra Software, known as the Smart Fractions. This development method employed Borg and Gall’s ten-stage method. These stages included preliminary research, product planning and development, preliminary product design, product validation, preliminary product revision, user trial, product revision, effectiveness tests, final product and mass production, and product dissemination and implementation. The research data corroborated the validity, effectiveness, and practicality of the Smart Fractions interactive learning media. Media experts, material and learning experts, and students as users have acknowledged these properties. A validity test demonstrated a value of V_a = 3.53, which implied a decent extent of validity. The practicality test through questionnaire and observation generated a practicality score of 86.67%, another decent product property. The product's effectiveness was tested by assessing students’ learning outcomes, which indicated an N-Gain score of 0.8. This inferred a noteworthy increase in computational thinking skills after implementing learning media. A t-test (2-tailed) also confirmed a significant difference in students' computational thinking skills before and after using learning media, as indicated by p = 0.000. The findings have concluded that Smart Fractions is a highly appropriate learning medium to improve students' computational thinking skills and help them visually understand fractions. The recommendation is to encourage students to use the learning media with the aid of manuals and tutorials on using the media. Teachers are also advised to combine the media with appropriate models, methods, strategies, and approaches.
