Published: October 2023

Villages, as the smallest part of the government administration system in Indonesia, are required to be able to follow technological developments and continue to improve their ability to manage village population administration data. Currently, the village is in the administrative service system. The villagers are still conventional; this affects village devices and villagers, where human error is common, as well as waste of time and costs. So it takes the use of the right technology to overcome this. Cloud computing is a paradigm that allows users to access information electronically using fixed devices or mobile devices connected to the internet network. Cloud computing offers PaaS (Platform as a Service) collaboration, on-demand services,and anytime, anywhere access capabilities. With cloud computing, digital village systems can be built. To be able to use the service, the village government must first subscribe to a cloud service provider.Based on the test results, it can be concluded that the implementation of Kebun Kelapa Village administration provides convenience in processing village population data, reduces village operational costs, and can provide more optimal administrative services to villagers, especially Kebun Kelapa.
Endometrial receptivity: The journey so far
Authors: Osazee K  , Omorogiuw A
Published: October 2023

Implantation is an act of coordinated interaction between the nascent blastocyst and a receptive endometrium mediated by the molecular and cellular interplay in a spatiotemporal manner. Though the advent of modern technology has enhanced the availability of relatively good quality embryos; the implantation rate has not positively correlated. Unlike the human embryo, the study of implantation is laden with ethical and technical challenges. Hence, most of the data on the process of implantation derived from animal studies. Unfortunately, there is wide variation in implantation process among animal species. Thus, cannot be transposed for a human. Hence, the in-vivo model remained the basis for the study of the mechanism of implantation. Research directed towards this direction may help in optimising the outcome of Assisted Reproduction Technology (ART).

Published: October 2023

Introduction: Placenta praevia complicates approximately 0.3-0.8% of pregnancies in multiparous parturient and there is an increased risk in those with previous Caesarean section. The choice of anaesthetic technique usually poses dilemma to the attending anaesthetist. The aim of this study was to review the choice of anaesthetic technique for caesarean section complicated by placenta praevia and determine foeto-maternal outcome.Patients and Methods: This was a retrospective survey covering a period of four years (January 2013 - December 2016). After Ethics Committee approval, information was obtained from the anaesthetic and theatre records and the patients’ case notes. The information obtained were: patients’ characteristics, obstetric history, grade of placenta praevia, indications for surgery, choice of anaesthetic technique, PCV/haemoglobin level, haemodynamic changes, blood transfusion, maternal and foetal outcome. The data were analysed using IBM SPSS version 20.Results: A total of 4,388 Caesarean sections were carried out during the 4- year period of review. One hundred and forty-five cases (3.3%) with different degrees of placenta praevia progressing to Caesarean section were identified. The mean age (years) was 32.6+5.3 with a mean gestational age(weeks) of 36.7±1.11.  Thirty-nine (26.9%) patients were offered general anaesthesia while 106 (73.1%) were done under spinal anaesthesia. The mean blood loss in the GA and spinal group was 1,080 + 970.53 and 753.77 + 568.19 ml respectively (P = 0.0135). 87.6% neonates were delivered alive. Seventy-nine (54.5%) were elective procedure with adequate preparation.  There were two (1.4%) cases of maternal mortality and perinatal mortality of 12.4%.Conclusion: The anaesthetic technique for patients with placenta praevia should be determined by the patient’s haemodynamic status and the grade of the placenta praevia.

Ten-month In Vitro Study of Marginal Adaptation and Micropermeability in Class II Restorations Made with Matrix-modified Composites
Authors: Yantcheva Sevda
Published: October 2023

The aim of the present in vitro study was to compare the marginal adaptation and micropermeability of class II restorations with a gingival wall, located 1 mm below the enamel-cementum junction, restored with two conventional dimethacrylate composites (Filtek P60 and Filtek Ultimate), and two innovative composites with a modified polymer matrix (Venus Diamond and Kalore) over ten months of ageing. The marginal adaptation to the proximal margins of the cavity was analyzed and evaluated by the SEM. The dye method was used to assess the micropermeability, and the analysis was performed using a stereomicroscope. The same samples were used for both studies. A correlation analysis was done based on the data to establish the relationships between marginal adaptation and micropermeability.
 
A statistically significant difference in the estimates for marginal adaptation of materials to the gingival, vestibular, and lingual proximal edges for values of excellent marginal adaptation ($$p<0.005$$) was found.
F.P60 differed significantly from V. Diamond and F. Ultimate. Kalore is arranged in the middle and does not differ considerably from the above two groups. According to micro permeability, a significant difference was found between F. Ultimate with better results and F.P60 and Kalore ($$p<0.005$$). There was a significant correlation ($$p=0.008$$) between the excellent scores for marginal adaptation to the edge of the gingival wall and micropermeability. It can be concluded that innovative high-molecular-weight composites do not significantly improve marginal adaptation and micropermeability in class II cavities, with a gingival wall located entirely in dentin.
A reductionist paradigm for high-throughput behavioural fingerprinting in Drosophila melanogaster
Authors: Jones Hannah , Willis Jenny A , Firth Lucy C , Giachello Carlo N G , Gilestro Giorgio F
Published: October 2023

Understanding how the brain encodes behaviour is the ultimate goal of neuroscience and the ability to objectively and reproducibly describe and quantify behaviour is a necessary milestone on this path. Recent technological progresses in machine learning and computational power have boosted the development and adoption of systems leveraging on high-resolution video recording to track an animal pose and describe behaviour in all four dimensions. However, the high temporal and spatial resolution that these systems offer must come as a compromise with their throughput and accessibility. Here we describe
coccinella
, an open-source reductionist framework combining high-throughput analysis of behaviour using real-time tracking on a distributed mesh of microcomputers (ethoscopes) with resource-lean statistical learning (HCTSA/Catch22). Coccinella is a reductionist system, yet outperforms state-of-the-art alternatives when exploring the pharmacobehaviour in
Drosophila melanogaster

Human Attention during Goal-directed Reading Comprehension Relies on Task Optimization
Authors: Zou Jiajie , Zhang Yuran , Li Jialu , Tian Xing , Ding Nai
Published: October 2023

The computational principles underlying attention allocation in complex goal-directed tasks remain elusive. Goal-directed reading, i.e., reading a passage to answer a question in mind, is a common real-world task that strongly engages attention. Here, we investigate what computational models can explain attention distribution in this complex task. We show that the reading time on each word is predicted by the attention weights in transformer-based deep neural networks (DNNs) optimized to perform the same reading task. Eye-tracking further reveals that readers separately attend to basic text features and question-relevant information during first-pass reading and rereading, respectively. Similarly, text features and question relevance separately modulate attention weights in shallow and deep DNN layers. Furthermore, when readers scan a passage without a question in mind, their reading time is predicted by DNNs optimized for a word prediction task. Therefore, we offer a computational account of how task optimization modulates attention distribution during real-world reading.
Leading an urban invasion: risk-sensitive learning is a winning strategy
Authors: Breen Alexis J , Deffner Dominik
Published: October 2023

In the unpredictable Anthropocene, a particularly pressing open question is how certain species invade urban environments. Sex-biased dispersal and learning arguably influence movement ecology, but their joint influence remains unexplored empirically, and might vary by space and time. We assayed reinforcement learning in wild-caught, temporarily-captive core, middle- or edge-range great-tailed grackles—a bird species undergoing urban-tracking rapid range expansion, led by dispersing males. We show: across populations, both sexes initially perform similarly when learning stimulus-reward pairings, but, when reward contingencies reverse, male—versus female—grackles finish ‘relearning’ faster, making fewer choice-option switches. How do male grackles do this? Bayesian cognitive modelling revealed male grackles’ choice behaviour is governed more strongly by the ‘weight’ of relative differences in recent foraging returns—i.e., they show more pronounced reward-payoff sensitivity. Confirming this mechanism, agent-based forward simulations of reinforcement learning—where we simulate ‘birds’ based on empirical estimates of our grackles’ reinforcement learning—replicate our sex-difference behavioural data. Finally, evolutionary modelling revealed natural selection should favour risk-sensitive learning in characteristically urban-like environments: stable but stochastic settings. Together, these results imply risk-sensitive learning is a winning strategy for urban-invasion leaders, underscoring the potential for life history
and
cognition to shape invasion success in human-modified environments.
Early prediction of student performance in CS1 programming courses
Authors: Llanos Jose , Bucheli Víctor A. , Restrepo-Calle Felipe
Published: October 2023

There is a high failure rate and low academic performance observed in programming courses. To address these issues, it is crucial to predict student performance at an early stage. This allows teachers to provide timely support and interventions to help students achieve their learning objectives. The prediction of student performance has gained significant attention, with researchers focusing on machine learning features and algorithms to improve predictions. This article proposes a model for predicting student performance in a 16-week CS1 programming course, specifically in weeks 3, 5, and 7. The model utilizes three key factors: grades, delivery time, and the number of attempts made by students in programming labs and an exam. Eight classification algorithms were employed to train and evaluate the model, with performance assessed using metrics such as accuracy, recall, F1 score, and AUC. In week 3, the gradient boosting classifier (GBC) achieved the best results with an F1 score of 86%, followed closely by the random forest classifier (RFC) with 83%. These findings demonstrate the potential of the proposed model in accurately predicting student performance.
Correlation Between the Infection Control Organizational Culture, Infection Control Fatigue, and Burnout
Authors: Oh Si-Yoon , Lee In-Soo
Published: October 2023

Emergency medical services (EMS) personnel play an important role in infectious disease control at the forefront of the emergency medical system. However, the increase in EMS personnel’s workload due to the prevalence of infectious diseases can negatively affect the practice of infection control. Accordingly, this study identified the infection control organizational culture, infection control fatigue, and burnout of EMS personnel and analyzed the correlation. In 2023, data on infection control organizational culture, infection control fatigue, and burnout were collected using a structured questionnaire for 104 participating EMS personnel in the Seoul metropolitan area. The findings showed that the personnel were unaware of the infection control organizational culture, and the degrees of infection control fatigue and burnout were high. The more negatively the personnel perceived the infection control organizational culture and the higher the infection control fatigue, the higher the burnout. Therefore, policies to manage EMS personnel’s infection control organizational culture, infection control fatigue, and burnout should be prepared and implemented.

Authors: Shukla Madhulika , Shukla Saurabh
Published: October 2023

Introduction: Determining the seroprevalence of Human Immunodeficiency Virus (HIV) in pregnant women offers essential data for monitoring the trend of HIV and assists in prevention from mother-to-child transmission. Aim: To determine the prevalence of HIV infection among pregnant women. Materials and Methods: A retrospective observational study was conducted at Autonomous State Medical College, Hardoi, Uttar Pradesh, India from July 2016 to June 2019. A total of 6,974 pregnant females were referred to the antenatal clinic during the study period, and all were included in this study. HIV antibodies were tested using the three ELISA/Rapid/Supplemental tests protocol. A woman was identified as HIV infected if tested positive on more than two HIV ELISA tests. The data were entered into MS Excel and analysed using Statistical Package for the Social Sciences (SPSS) version 22.0. A Chi-square test was employed to assess the association between the variables. Results: Out of 6,974 females, a total of 32 (0.46%) pregnant females were found to be seropositive (13 patients from July 2016 to June 2017, 10 patients from July 2017 to June 2018, and 9 patients from July 2018 to June 2019). Among the 32 HIV-positive pregnant women, 2 (6.3%) were aged <20 years, 19 (59.4%) were aged 21-30 years, 9 (28.1%) were aged 31- 40 years, and 2 (6.2%) were aged over 40 years. Illiteracy was associated with seropositivity, as 53.1% of seropositive patients were illiterate. Conclusion: Seroprevalence has been decreasing in recent years, indicating that we are on the right track. However, efforts should be made to provide universal access to antenatal care and services for prevention parent-to-child transmission of HIV/AIDS.

Introduction: Laparoscopic cholecystectomy can now be performed safely and effectively due to various surgical tools that have significantly reduced intraoperative and postoperative problems. The Harmonic® Scalpel (HS) is a superior option to more conventional Electrocautery (EC) because it reduces temperatures, smoke, and lateral tissue damage. The Harmonic® Scalpel also lowers the risk of injury due to minimal heat dispersion. Due to less trauma, there is a decrease in both moderate and severe bleeding. It is hypothesised that the HS might be a more cost-effective alternative to employing a variety of disposable tools, such as scissors, a clipper, an EC hook, and a grasper. Aim: To compare the effectiveness and safety of the HS compared to traditional EC in achieving complete dissection and haemostasis during laparoscopic cholecystectomies. Materials and Methods: A prospective interventional study was conducted with 300 patients diagnosed with chronic calculous cholecystitis, admitted to a tertiary care hospital under Department of General Surgery, from November 2020 to October 2022. Patients were allocated to two groups, and the outcomes of laparoscopic cholecystectomy were compared between the usage of a HS and EC in Calot’s triangle dissection and Gallbladder (GB) dissection from the GB fossa. Descriptive data were represented through frequencies and percentages. The means of the two groups were compared using t-test, and categorical variables were compared using chi-square test. Results: The mean age was 46.53±13.740 years in the HS group, while it was 45.3±13.961 years in the EC group. The average duration of dissection with a HS was 52.84±6.167 minutes and 56.79±5.582 minutes in the EC group (p-value 0.001). A total of 67 (44.7%) patients in the HS group had minimal or no bleeding, while it was 23 (15.3%) patients in the EC group. GB perforation occurred in 13 (8.7%) patients in the HS group and in 26 (17.3%) patients in the EC group. Liver injury occurred in 2 (1.3%) patients in the HS group and in 6 (4%) patients in the EC group. Postoperative nausea and vomiting were reported in 20 (13.3%) and 72 (48%) patients in the HS and EC groups, respectively, in the first 48 hours. All these associations were found to be statistically significant (p-value 0.001). Conclusion: The present study found that the HS offers a hassle-free dissection without much incidence of intraoperative bleeding or surrounding tissue damage.

Aims: Butterflies are the symbol and target species for conservation in many parts of the world, and are key indicators of an environment's ecological status. The abundance, brief generation time, quick movement, and sensitivity to climatic changes of the butterfly fauna make it a significant predictor. It is crucial for effective and suitable butterfly protection to conduct research on biodiversity, ecology, and habitat suitability.

Place and Duration of Study: The study was conducted in Ajmer City, Rajasthan, India. The four sites for butterfly collection were Open Land, Scrub Land, Aravalli Hills, and MDS University Campus to reflect the variety of environments in Ajmer. Scrub land makes up 1.5 km2, open ground 1.3 km2, the MDS University campus 0.5 km2, and the Aravalli hills 2 km2 of the 5.3 km2 research regions.

Methodology: For butterfly studies, the Pollard walk technique was used, with 20 fixed transects placed stratified and randomly across four environments. Adult butterfly individuals were noted while walking at a slow, steady speed within a assumptive 5 m radius and Alpha and Beta diversity analysis was performed using PAST 4.06 and Microsoft Excel 2010

Results: During the study, 54 butterfly species from five groups were identified. The most diverse families were Nymphalidae and Pieridae, then Lycaenidae, Hesperiidae, Papilionidae.

Conclusion: It is essential to track changes in the butterfly population as an indicator for climate and human impacts because they are sensitive to changes in their surroundings, they perform functions like pollinating various plant species. However, by planting appropriate trees, plants, and other vegetation that will support the organisms' continued health, we can at least try to lessen them. At a minimum, this attempt will prevent the common species from facing extinction.

Watershed morphological and hydrological properties can be derived from the drainage morphometric parameter. Morphometric analysis with the help of remote sensing and GIS techniques is considered to be the most useful approach for prioritization of watersheds. The main aim of the study is to evaluate the morphometric parameters of Kantori nala milli watershed located at Mahasamund district of Chhattisgarh state, India. This study outlines the significance of digital elevation model for assessment of drainage pattern and extraction of relative parameters. Milli watershed was automatically delineated and divided into eleven micro watersheds MWS 1 to MWS 11 on the basis of topography from the Depression less Digital Elevation Model (DEM) with 10 m resolution prepared by Inverse Distance Weighted (IDW) interpolation technique. Stream order in study area milli watershed ranges from one to two. Each parameter has been assigned their ranks according to their value. Thereafter, an average value of the rank score for each of the micro watershed is calculated. The micro watershed with the lowest compound factor (Cp) was given the highest prioritized rank out of the group of micro watersheds, and vice versa. The result from the priority ranking of morphometric analysis shows that MWS 7 is having high priority while MWS 8 is having low priority. Micro watersheds MWS 9 and MWS 11 falls under same priority i.e. 6 and also micro watersheds MWS 2 and MWS 4 falls under same priority i.e. 7. To control soil erosion, various land rehabilitation programmes and bioengineering methods should be adopted on the micro watershed of high priority categories, followed by medium and low priority categories.

A chlorophyll meter measures the greenness of leaves and can indicate the chlorophyll content and N status. Therefore, by using a chlorophyll meter, proxy information related to the leaf N content could be obtained and this would avoid the need of laborious laboratory analysis. Keeping in this view a field experiment was conducted during winter (Rabi) 2019 growing season at the experimental field of JNKVV, Jabalpur to estimate crop nitrogen (N) and chlorophyll content in wheat using SPAD. The treatment comprised of 3 sources of nutrient M1- Inorganic sources (NPK fertilizers), M2- organic sources (FYM, vermicompost, biofertilizers Azotobacter and PSB) and M3- Integrated sources (50% Inorganic + 50% organic) as main treatments and 5 NPK levels S1- control, S2- 100% RDF, S3- 150% RDF, S4- 200% RDF, S5- Based on soil test value for target yield of 6t ha-1 as sub treatments were replicated thrice in a split plot design. The results showed that the correlation (r = 0.94, 0.90, 0.92 and 0.94, respectively) and coefficient of determination (R2 = 0.96, 0.94, 0.83 and 0.94, respectively) was significantly and positively correlated with SPAD and nitrogen concentration in leaf. Similarly significant and positive correlation (r = 0.84, 0.76, 0.78 and 0.71, respectively) found with SPAD and total chlorophyll values. Coefficient of determination (R2) SPAD with chlorophyll and leaf N concentration proved to be significant (R2 = 0.75, 0.76, 0.54 and 0.85, respectively) at different growth stages. It was concluded that SPAD meter are useful for the determination of proxy chlorophyll and total nitrogen content of wheat plant.

Medical waste has enormous consequences for human health and the environment. It has the potential to cause severe disease, if not death. If drugs end up near wildlife refuges like parks, lakes, and other natural environments, whole populations of species might be wiped off therefore its  management is vital due to the potential for environmental and public health hazards, especially in countries which are in the process of development. It is crucial to collect data and examples from a developed nation or a nation with an efficient medical waste management system. Cities are expected to accommodate 65 percent of the globe's population by 2030. The amount of residential waste produced in Mumbai on a regular basis is approximated to be the equal of an eight-story building complex. The atmosphere in cities is so bad that an estimated two million kids under the age of five die from respiratory problems each year.  Hospitals, retail stores selling vegetables, seafood, and other items, as well as bus stops, train stations, and amusement parks, are all filthy and serve as breedi­ng grounds for dangerous diseases. In developing nations like India, the amount of trash generated by hospitals is significantly rising, hence monitoring is important. The growing interest for public health excellence and pollution management, necessities that the large quantity of hazardous waste be rendered as innocuous very quickly, prior to its disposal. The main aim of this paper is to highlight the issues surrounding medical waste, its environmental repercussions, and the management procedure.
