Atypical lichen myxedematosus: a rare case with complete resolution of skin
Authors: Karthiga S. , Nusair M. S. M. , Mayurathan P.
Published: February 2024

Lichen myxedematosus (LM) is a rare disorder classified into three categories based on the type and distribution of skin lesions: generalised (scleromyxoedema), localised, and atypical variants. Scleromyxoedema, often associated with monoclonal gammopathy, exhibits multi-organ involvement and necessitates specific treatments such as intravenous immunoglobulin. Localised LM has benign characteristics and typically does not progress to scleromyxodema. The atypical variant does not meet the criteria of the previous two categories and may resolve spontaneously. We present a case of a 45-year-old woman who manifested an erythematous papular lesion on both shins over three months, which spontaneously resolved over one month. A skin biopsy confirmed the diagnosis of Lichen myxedematosus. However, clinical features were not suggestive of either Scleromyxodema or localised LM. The Patient was diagnosed to have an atypical variant of LM because the lesion, which was confined to bilateral shins, completely resolved within a month and was not associated with paraproteinemia. This report highlights the challenges in diagnosing and managing such atypical cases.

Authors: Wariyapperuma U. M. , Atapattu P. M. , Fernando A.
Published: February 2024

Introduction: The Faculty of Medicine, University of Moratuwa, established during the COVID-19 pandemic, was compelled to conduct the teaching activities online for the first intake of students until their first bar examination. Online learning is known to be linked to several health issues. This study aims to explore the academic performance and perceived health effects related to online learning in the Faculty of Medicine, Moratuwa.Methods: A descriptive cross-sectional study was conducted among all 104 first-intake students using an anonymous online self-administered questionnaire to explore health effects and academic performance after ethical clearance.Results: Out of 104 students, 82 students responded (response rate=78.85%). Majority participated from home using their own laptop (74.4%) and personal Wi-Fi (69.5%) and spent 5-10 hours daily for online academic activities (72%). Majority complained of related physical (86.6%), and psychological (81.7%) health issues: eye problems (69.5%), headache (47.6%), backache (43.9%), stress (46.3%) and concentration difficulties (45.1%). The first bar examination was cleared by 84.1% with the majority (52.4%) obtaining classes. There was a statistically significant positive association (p< .05) between physical and psychological health concerns with the average screen-time spent on academic activities, but not with the academic performance. There was also no statistically significant association between screen-time and academic performance.Conclusions: Majority of students using online learning had related physical and psychological health issues which were positively associated with the screen-time though not with academic performance. Designing online activities with less screen time may be considered as a strategy to minimise health effects related to online learning.

Authors: Rampazzo Giulia , Zironi Elisa , Depau Giacomo , Pagliuca Giampiero , Gazzotti Teresa
Published: February 2024

Glyphosate and glufosinate are among the most widely used pesticides in agriculture worldwide. Their extensive use leads to the presence of their residues on crops and in the surrounding environment. Beehives, bees, and apiculture products can represent potential sources for the accumulation of these substances and their metabolites, and the consequences for bee health, as well as the level of risk to human health from consuming contaminated food, are still unclear. Furthermore, information on the contamination levels of honey and other beehive products by these compounds remains poorly documented. This study is part of a broader research effort aimed at developing specific analytical methods for monitoring the level of these contaminants in bee products. The methodology employed enabled the acquisition of preliminary information concerning the levels of glyphosate and glufosinate contamination in honey samples obtained from various retailers in Italy to assess compliance with the limits established by Regulation 293/2013. The liquid chromatography tandem mass spectrometry analysis of the 30 honey samples revealed quantifiable levels of glyphosate in eight samples, with contamination ranging from 5.4 to 138.5 ng/g. Notably, one sample of the wildflower type showed residue levels nearly three times the maximum residue limit. Additionally, trace levels of glyphosate contamination were detected in another ten samples. It is noteworthy that glufosinate and its metabolites were not detected in any of the analyzed samples within the established method’s detection ranges.

Lymphatic filariasis (LF) is a leading cause of disability due to infectious disease worldwide. The Recife Metropolitan Region (RMR) is the only remaining focus of LF in Brazil, where the parasite Wuchereria bancrofti is transmitted solely by the mosquito Culex quinquefasciatus. This study reports the results of transmission assessment surveys and molecular xenomonitoring in the city of Olinda, RMR, after nearly 15 years (2015–2016) of interventions for LF elimination. Participants were screened for W. bancrofti antigen via immunochromatographic card tests (ICT) in: 1) door-to-door surveys conducted for all children aged 5–7 years from 4 out of 17 intervention areas treated with at least five annual doses of mass drug administration (MDA), and 2) a two-stage cluster sampling survey of residents aged 5 years and older in non-MDA areas. Mosquitoes were collected via handheld aspirators in four MDA areas, differentiated by species, sex, and physiological status, pooled into groups of up to 10 blood-fed, semigravid, and gravid mosquitoes, and screened for W. bancrofti infection by real-time quantitative polymerase chain reaction (RT-qPCR). All 1,170 children from MDA areas and the entire population sample of 990 residents in non-MDA areas were ICT negative. In MDA areas, a total of 3,152 female Cx. quinquefasciatus mosquitoes in 277 households (range, 0–296 mosquitoes per house) were collected via aspiration. RT-qPCR of 233 pools of mosquitos were negative for W. bancrofti RNA; an independent reference laboratory confirmed these results. These results provide evidence that LF transmission has been halted in this setting.

Published: February 2024

Type 2 leprosy reaction is a type of acute inflammation that predominantly affects borderline lepromatous leprosy and lepromatous leprosy patients and occurs before, during, or after therapy. The atypical variant, which resembles Sweet syndrome, could easily lead to misdiagnosis. Here, we report a case of a 52-year-old man who presented with type 2 leprosy reaction that mimicked Sweet syndrome. In addition, we review published cases and summarize their features to raise awareness of this atypical variant to enable improved diagnosis and management.

Published: February 2024

Anopheles darlingi is the primary malaria vector in the Amazon region and is highly susceptible to both Plasmodium vivax and Plasmodium falciparum parasites. Although anopheline mosquitoes may develop melanotic encapsulation in response to Plasmodium parasites, there is no record of An. darlingi exhibiting a melanization response to P. vivax, the main malaria parasite in the Americas. Here, we report the occurrence of P. vivax sporozoite melanization in An. darlingi mosquitoes.
The Drivers of Low Vaccination Utilization in Niger
Authors: Seytre Bernard , Chaibou Sanoussi , Simon Bernard
Published: February 2024

Vaccination adherence involves the expected benefit of a vaccine and the perceived risk of the disease. To develop an evidence-based communication strategy aimed at improving vaccination coverage in Niger, we conducted a mixed socio-anthropological study of the perceptions among the population on the benefit and the risk of the childhood (Expanded Program on Immunization) and the COVID-19 vaccines. Our results show that negative rumors are not a significant driver of vaccine refusal. The insufficient level of fully vaccinated, compared with partially vaccinated, children might be explained by misunderstandings around the side effects of vaccines and the necessity for full vaccination. Approximately one-fourth of the population is vaccinated against COVID-19, whereas 73.3% think that vaccines against the disease are a “good thing,” and 83% of those who have heard messages promoting the vaccination approve of them. This apparent contradiction is explained by a low perception of the risks of COVID-19. More than half of the population surveyed believe that the disease is not present in the country. A large majority believe that only ill people can transmit the disease, whereas only 12.8% think they know anybody who has ever been sick with COVID-19. Three-fourths of the interviewees have seen images from around the world of persons sick or deceased from COVID-19; the same proportion has not seen any such images of affected patients in Niger. Communication to improve COVID-19 uptake should focus on the reality of the disease presence and its transmission and not on rumors surrounding the vaccines.
Toward an Integrated Transportation Pricing Approach Using
Vehicle-based Technologies
Authors: Sethi Sonika S.
Published: February 2024

A suite of recent policy and legislative initiatives are prioritizing a shift
towards electrification of the personal-use vehicle fleet. This agenda is
intimately tied to another complex issue: the sustainability of the primary
transportation funding source (i.e., the gas tax—also known as the motor fuel
tax). What makes this particularly hard is that gasoline consumption is only a
proxy for “amount of travel.” With diversification in fuel sources and a
concerted movement towards non-fossil fuel sources to power vehicles, any
specific fuel source would be (at best) a weak or (at worst) grossly inequitable
representation for amount of travel.

Toward an Integrated Transportation Pricing Approach Using Vehicle-based
Technologies will focus on some of the larger questions for an
integrated pricing system based on miles driven that are measured directly using
vehicle-based or in-vehicle technology communicating directly with
infrastructure systems.

Authors: Phillips Paul
Published: February 2024

The adoption of metallic additive manufacturing (AM) for heat exchangers offers
significant thermal management benefits that range from optimized heat energy
transfer to supporting integrated designs that can reduce weight, size, and
component numbers. The benefits offered by utilizing AM for heat exchangers
transcend industries and have relevance within the aerospace and automotive
industries, where new mobility requirements result in the need for efficient
energy systems, increasingly efficient component design, and higher
temperatures.

Additive Manufacturing of Thermal Management Components in Mobility

Exploring the Quality of Feedback in Entrustable Professional Activity Narratives Across 24 Residency Training Programs
Authors: Clement Elizabeth A. , Oswald Anna , Ghosh Soumyaditya , Hamza Deena M.
Published: February 2024

Background Competency-based medical education (CBME) has been implemented in many residency training programs across Canada. A key component of CBME is documentation of frequent low-stakes workplace-based assessments to track trainee progression over time. Critically, the quality of narrative feedback is imperative for trainees to accumulate a body of evidence of their progress. Suboptimal narrative feedback will challenge accurate decision-making, such as promotion to the next stage of training.

Objective To explore the quality of documented feedback provided on workplace-based assessments by examining and scoring narrative comments using a published quality scoring framework.

Methods We employed a retrospective cohort secondary analysis of existing data using a sample of 25% of entrustable professional activity (EPA) observations from trainee portfolios from 24 programs in one institution in Canada from July 2019 to June 2020. Statistical analyses explore the variance of scores between programs (Kruskal-Wallis rank sum test) and potential associations between program size, CBME launch year, and medical versus surgical specialties (Spearman’s rho).

Results Mean quality scores of 5681 narrative comments ranged from 2.0±1.2 to 3.4±1.4 out of 5 across programs. A significant and moderate difference in the quality of feedback across programs was identified (χ2=321.38, P<.001, ε2=0.06). Smaller programs and those with an earlier launch year performed better (P<.001). No significant difference was found in quality score when comparing surgical/procedural and medical programs that transitioned to CBME in this institution (P=.65).

Conclusions This study illustrates the complexity of examining the quality of narrative comments provided to trainees through EPA assessments.

Published: February 2024

Background Studies across specialties have demonstrated gender disparities in feedback, learner assessments, and operative cases. However, data are limited on differences in numbers of procedures among residents.

Objective To quantify the association between gender and the number of procedures reported among emergency medicine (EM) residents.

Methods We conducted a retrospective review of procedural differences by self-identified gender among graduating EM residents at 8 separate programs over a 10-year period (2013 to 2022). Sites were selected to ensure diversity of program length, program type, and geography. Residents from combined training programs, those who did not complete their full training at that institution, and those who did not have data available were excluded. We calculated the mean, SD, median, and IQR for each procedure by gender. We compared reported procedures by gender using linear regression, controlling for institution, and performed a sensitivity analysis excluding outlier residents with procedure totals >3 SD from the mean.

Results We collected data from 914 residents, with 880 (96.3%) meeting inclusion criteria. There were 358 (40.7%) women and 522 (59.3%) men. The most common procedures were point-of-care ultrasound, adult medical resuscitation, adult trauma resuscitation, and intubations. After adjusting for institutions, the number of dislocation reductions, chest tube insertions, and sedations were higher for men. The sensitivity analysis findings were stable except for central lines, which were also more common in men.

Conclusions In a national sample of EM programs, there were increased numbers of dislocation reductions, chest tube insertions, and sedations reported by men compared with women.

Published: February 2024

Background We started a primary care residency program intended to prepare graduates for primary care and increase entry into primary care, using time-limited funds from the Health Resources and Services Administration (HRSA).

Objective To compare the graduates of the primary care residency program to their categorical peers, and whether they remained in the state, began primary care careers, and whether they identified as underrepresented in medicine.

Methods This is a retrospective study of a cohort of 39 residents who graduated from the University of North Carolina primary care residency program from 2014-2023. In 2016, HRSA grant funding expired and the program continued with ongoing financial support from the 2 institutions. Graduate demographics and career choices were compared to categorical residents (159 total) for graduate years 2014 to 2023.

Results The primary care pediatrics residency has graduated 39 residents to date. Job placement data was obtained for all 39 graduates. Graduates of the program have 5.5-fold greater odds (95% CI, 2.5-12.5) of working in primary care roles following graduation than peer categorical residents. Most graduates (33 of 39, 85%) have taken jobs in general pediatrics (including primary care, urgent care, adolescent medicine, or hospital medicine). The program has recruited a large proportion of its residents (12 of 39, 31%) from groups historically underrepresented in medicine.

Conclusions We developed an innovative primary care pediatric residency in collaboration with a community partner, spurred by HRSA funds, that has trained a diverse group of new primary care pediatricians.

Published: February 2024

Obsolete mobile phones form a major component of the e-waste stream. The Printed wiring boards (PWBs) of mobile phones are packed  with economic and toxic metals. Regulatory bodies such as Restriction of Hazardous Substances (RoHS) directives regulate the amount of  these toxic metals in electrical and electronic equipment. This study is aimed at evaluating selected critical metals present in PWBs of  three popular brands of discarded mobile phones used in Nigeria to understudy the behaviour of original equipment manufacturers  (OEMs) regarding toxicity, economic potentials, and level of compliance with international initiatives by regulatory bodies to reduce the  level of toxic metals in electronic equipment. PWBs obtained from 60 discarded mobile phones of 3 popular mobile phone brands used in Nigeria were chopped into smaller particles, extracted according to EPA 3050B method, and analysed using the Inductive Coupled  Plasma-Optical Emission Spectrometry technique. It was observed that Mn, Fe, Zn, and Cu, had the highest concentration range across all  brands studied. Notable toxic metals such as Pb, Cd, Cr, and As have mean and standard deviation values of 0.43±0.38 mg/kg,  0.62±0.160 mg/kg, 5.16±1.06 mg/kg, and 84.97±13.83 mg/kg respectively. Economic metals: Cu, Ag, and Au had mean and standard  deviation values of 80.37±16.89 mg/kg, 2.12±0.43 mg/kg, and 0.95±0.19 mg/kg respectively. Results from the study indicate that PWBs of  mobile phones are a perfect secondary source of a large variety of metals vital for the recycling industry. Also, the low levels of toxic metals suggest that some OEMs are already adopting the 'design-for-environment' option. Therefore, PWBs studied seem eco-friendly;  however, need to be handled with care as there are still some toxic metals of concern not determined in this study.
Whisking away the veil: exploring feline immunodeficiency virus and feline leukaemia virus prevalence among shelter cats in Portugal
Authors: Afonso Paulo , Cardoso Luis , Quintas Hélder , Coelho Ana Cláudia
Published: February 2024

Feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) are important pathogens affecting feline hosts worldwide, compromising the health, well-being, quality of life, and lifespan of infected cats. This study explores the prevalence of these viral agents among shelter cats in Portugal, aiming to unravel their complexities and implications. The prevalence of FIV and FeLV was assessed by collecting blood samples (n = 326) from cats during medical routine check-ups at shelter admission and testing them with an immunochromatographic kit. The overall seroprevalence of FIV and FeLV was 15.3% (50/326, 95% confidence interval [CI]: 11.6–19.7). The proportion of cats positive to FIV, FeLV, and both FIV and FeLV was 9.8% (32/326, 95% CI: 6.8-13.6), 2.1% (7/326, 95% CI: 0.9-4.4) and 3.4% (11/326, 95% CI: 1.7-6.0), respectively. The prevalence of FIV and both FeLV and FIV appeared to be higher in the adult population. No statistical association was found between sex, breed, hair, or municipality, and FeLV, FIV and both FeLV and FIV prevalence. This is the first report on retroviral prevalence in shelter cats in Portugal, which provides important information regarding FIV and FeLV among stray cats in Portugal, highlighting the need for surveillance of those viruses, improved compliance with vaccination programmes, and vigilant management strategies to limit and control these viruses in the felinepopulation.
Breeding season and body condition influence on zootechnical parameters of Ouled Djellal ewes in semi-arid areas
Authors: Taherti Mourad , Ait Isad Nassima , Mimoune Nora
Published: February 2024

In this study, a database was created by monitoring 3000 Ouled Djellal ewes, belonging to ten breeding farms and representing two modes of reproduction management. The data collected make it possible to measure the reproductive performance of females and to determine the influence of non-genetic factors on different parameters. The Body Condition Score (BCS) was calculated to compare performance in relation with breeding conditions. The results showed that fertility and prolificacy accounted for 91.1±0.1% and 116.4±0.2% in the reproduction mode respectively based on one lambing/year with exclusive spring control, and of 53.5±0.2% and 101.2±0.1% respectively in the traditional lambing system spread overthe year (with the ram permanently present in the flock) (P<0.05). The BCS varied according to mating season and feeding system. Indeed, as the BCS at mating increased, fertility, prolificacy and productivity improved. Ewes whose BCS at mating was equal to or greater than 3 obtained the best performance, while those with a lower BCS were less fertile, less prolific, and less productive. The average productivity of Ouled Djellal sheep was 107.0±0.1%, and 54.8±0.3%, respectively, in the first and second mode of reproduction management (P<0.05). This study highlights the main sources of variations and their interactions.
Genetic characterisation of the domestic cat population (Felis catus) in Valledupar – Cesar using coat markers
Authors: Pardo-Pérez Enrique , Cavadía-Martínez Teodora , Causil-Vargas Luis
Published: February 2024

The domestic cat (Felis catus) is a small carnivorous mammal belonging to the feline family. It is characterised by significant variability in terms of breeds, with females commonly smaller than males. Cats are one of the most popular pet species worldwide, though there is growing evidence that their large populations are having negative effects on the environment. Cats exhibit noticeable polymorphisms, particularly related to the colour, pattern, and texture of their coat, which can be easily recognised by visual inspection. This makes data collection a straightforward procedure. Cats are an ideal species for population studies because they are cosmopolitan animals and form a panmictic population. Genetic population analyses of cats are essential for understanding the history of their evolution and for developing phylogenetic hypotheses about allele relationships. However, despite the importance of these studies, global information availability is limited and, in some areas, completely absent. The aim of this study wasto determine the level of genetic diversity and structure in domestic cat populations using coat markers in Valledupar, Cesar. Random sampling was conducted between February and September 2022, and 365 adult animals were phenotypically identified in twelve neighbourhoods of the locality. The genes studied included Orange, Agouti, Dilution, Tabby, Long Hair, Siamese, Manx, Spotting White, and Dominant White. The Non-agoutimarker showed the highest frequency (0.740), while the Manx gene exhibited the lowest value. Most of the genetic diversity was found within populations and was limited between populations. Additionally, high gene flow, an excess of heterozygotes, and reduced genetic differentiation between populations were observed. The Spotting White locus showed a departure from Hardy-Weinberg equilibrium. Genetic distance between populations and the obtained dendrogram revealed low significant values, indicating that the populations as a whole are closely related.
Difference Adder Graph Algorithm for Reducing LUT Size
Authors: A Umamaheswari , Pushpa S. Ewins Pon
Published: February 2024

The current study introduces an implementation of the Difference Adder Graph Algorithm (DAGA) using Verilog. DAGA, rooted in graph theory and adder circuits, aims to diminish Look Up Tables (LUTs) and power consumption in Field Programmable Gate Arrays (FPGAs). By reducing the number of LUTs required for a specific functionality, DAGA offers a promising alternative for digital circuit optimization. To evaluate its efficacy, the paper contrasts DAGA with the Multiple Constant Multiplication (MCM) method, which leverages Carry Save Adder (CSA) architecture and exploits signed-digit number representations to minimize LUT usage. Experimental findings reveal DAGA's superiority over MCM in both area and power utilization reduction. Implementation details and results indicate a remarkable 49.29% reduction in LUT count and a corresponding 41.8% decrease in power consumption for digital circuits. These outcomes underscore the effectiveness of DAGA in enhancing FPGA efficiency, highlighting its potential as a valuable tool for digital circuit designers seeking to optimize performance and power utilization.
EVOLUCIJA ODNOSA MAJKE I KĆERKE U ITALIJANSKOM FEMINIZMU DRUGOG TALASA
Authors: Đorđević Aleksandra
Published: February 2024

With the development of feminist emancipatory concepts, the maternal figure as a symbol of the patriarchal structure becomes a frequent object of criticism. The search for identity has meant the discovery of the female side, that in patriarchy has been subordinated and manipulated for a very long time. The approach towards the mother has undergone many changes, from rejecting the mother in the late sixties when the mother was perceived as part of an authoritarian system, to viewing the mother as a victim of repression, as seen by feminists in the seventies. Critical analysis of philosophical, mythological, religious, and psychoanalytic theories linking motherhood to biology, nature, and submission has led to a change in the perception of motherhood, which over time begins to be seen as a source of creative inspiration. The paper provides an overview of the basic characteristics of Italian second-wave feminism and its most prominent representatives. It then seeks to analyze the evolution of the mother-daughter relationship, primarily through the principles and development of the feminist continental wave, and the influence that the most significant Italian feminists have had on the literary corpus and culture of this country.

Authors: Halim Michelle
Published: February 2024

Price perception and brand image are prominent factors that influence consumers' propensity to buy a product. However, in the context of high credence product, their influence on brand loyalty is still in open to study. Using Innisfree as a research context, the researcher aims to study whether the two variables affect attitudinal loyalty. For that purpose, the researchers constructively replicated Adawiah's (2015) research model by adding attitudinal loyalty as an endogenous variable and price perception and brand image as exogenous variables. Data were collected using Google Forms from 150 respondents selected purposively. The analysis using Structural Equation Modeling with WarpPLS 7.0 shows that price perception and brand image have a positive and significant effect on the attitudinal loyalty. Further research can involve behavioral loyalty as an additional endogenous variable.

Aim: To investigate whether inflammation plays a role in the pathogenesis of patients diagnosed with overactive bladder (OAB).
Material-Method: Patients who applied to the urology outpatient clinic with a preliminary diagnosis of OAB between March 2022 and September 2023 and were diagnosed were prospectively included in the study. Demographic data of the patients, such as age, gender and body mass index (BMI), were recorded. The number of urgency attacks, pollakiuria and nocturia, OAB-V8 scores (0-40) and the anticholinergics used were recorded. Blood group, whole blood and biochemical values measured from peripheral blood at outpatient clinic admissions, among the inflammation markers neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), lymphocyte-monocyte ratio (LMR), C reactive protein/albumin (CRP/Albumin) ratio and Deritis (AST/ALT) ratios were recorded.
Patients with urinary tract infection, renal function test abnormalities, and patients with a history of previous urological surgery were excluded from the study. Patients who presented to the outpatient clinic with non-OAB were included as the control group. Hemogram and biochemical values of these patients were also recorded.
Data recorded at baseline were compared between groups.
Results: A total of 198 patients were included in the study (OAB group n: 99, control group n: 99). The mean age of all patients was 52.3±15 years, and the mean OAB-V8 score was 11.9±9.9.
No statistically significant difference was observed between the groups in terms of gender and blood group. No statistically significant difference was observed between the groups in terms of hemoglobin, hematocrit, lymphocyte, platelet, AST, ALT, albumin, NLR, LMR, PLR, Deritis, MLR and CRP/albumin ratio. The mean age of the OAB group was found to be significantly higher than the control group (p

Published: February 2024

Diabetes is one of the most widespread chronic diseases worldwide. More than 400 million people in the world suffer from it, and their number is increasing significantly every year. The continents of the world, especially Asia and Africa, are experiencing a high rate of infection due to a number of factors and environmental factors. Related to diet and healthy habits used in many developing countries. Diabetes is considered one of the most serious chronic diseases that affect the human body due to impaired secretion of the hormone insulin, because the pancreas is unable to secrete a sufficient amount of insulin, or when the cells of the human body do not accept insulin and don't use it. Effective, causing a sudden drop or rise in blood sugar levels. It has a huge impact on human health and type 2 diabetes is the most common form in humans as many factors contribute to its spread, such as genetic factors, poor diet and lack of regular exercise.

Published: February 2024

The ever-evolving cybersecurity sector requires robust intrusion detection systems (IDS). Traditional rules-based measures are no longer sufficient due to the complexity of cyber threats, requiring new approaches. This study presents the architecture of an intrusion detection system combining machine learning and principal component analysis (PCA) to increase network security. A network traffic classification system was built and tested on the NSL-KDD dataset and used PCA for dimensionality reduction. The results were cross-validated to reduce overfitting and ensure generalizability of the model. Low-variance precision refers to the consistency of the cross-validation fold. The combination of PCA and machine learning models exceeds previous studies with an F1 score for the random forest model of over 99%. The study improves intrusion detection and network protection against cyber-attacks.

Clean water is one of the basic needs that is needed and is an important concern in a residence for human survival. The condition of the springs is estimated to have experienced a decrease in water quantity due to human activities and changes in quality due to the change of dry and rainy seasons as well as traditional activities. This research aims to determine the quality and quantity of spring water based on physical, chemical and biological parameters based on RI Minister of Health Regulation No. 32 of 2017. These parameters are turbidity, color, TDS, temperature, odor, pH, Nitrate, Nitrite, Cr 2+, Iron, Mn, Total Coliform, E-Coli. The method used is a survey method for sampling and measuring discharge. The results show that the Total Coliform, E-Coli and Temperature parameters exceed the quality standards. This is an indication that there is a result of the dissolution of chemicals from the agricultural activities of local residents as well as the existence of the ruwatan tradition which uses organic materials put into ponds. Water quality that does not meet quality standards will affect public health and the surrounding environment.

Springs are one of the water sources that people can use to meet their clean water needs. The Balinese people in particular, apart from using spring water to fulfill their daily needs, also use it as a means of religious ceremonies so that its sustainability is strictly maintained. One of the springs that can be found in Bali is the Tirta Salaka spring. Tirta Salaka spring is located in Sading Village, Mengwi District, Badung Regency, Bali Province. The purpose of this study was to analyze the effect of surface water availability on Tirta Salaka springs. The method used in the research is a combination of quantitative and analytical methods. Based on calculations, the discharge value of the Tirta Salaka spring is smaller than the general water balance value from November to March. The discharge value of the Tirta Salaka spring from November 2022 to March 2023 is included in class VI with values of 1.111.931 liters/month, 1.196.208 liters/month, 1.413.677 liters/month, 1.036.800 liters/month, and 914.717 liters/month. This shows that the amount of discharge from the Tirta Salaka spring is influenced by rainfall. The higher the rainfall value, the higher the discharge of the Tirta Salaka spring

: Rawa Singkil is a former river-lake formed in Pondok and Parangjoro Village, Grogol District, Sukoharjo Regency, Central Java Province due to the straightening of the Bengawan Solo river. Land use and the buildings construction around Rawa Singkil ignore the regulations and river strips. Erosion around Rawa Singkil has the potential to cause siltation. Siltation can reduce the capacity of Rawa Singkil as a reservoir for rainwater runoff to prevent overflow flooding. This study was conducted to calculate the amount of erosion rate, Erosion Hazard Level (EHL) and the effect of rainfall intensity on erosion in Rawa Singkil. The stick method is used to measure the rate of erosion while the intensity of rainfall is measured actually based on the volume and duration of rain using a simple observatory-type rain measuring device. The results showed the largest erosion and EHL in LP-2, LP-3, LP-8, LP-9, and LP-11 respectively, namely: 438.826 tons / Ha / year Weight EHL (BIII); 62,255 tonnes/Ha/year medium EHL (S II); 447,681 tons/Ha/year weight EHL (B III); 57,025 tons/Ha/year light EHL (R I); 488,628 tonnes/Ha/year Very heavy EHL (SB IV). Correlation and regression tests indicate that rainfall intensity and rain duration specifically affect erosion rates

The purpose of this paper is to look at the impact of financial and non-financial aspects on voluntary disclosure as a broader form of disclosures. With total of 15 organizations used as samples, obtained from the Indonesia Philanthropy directory in April 2021 by purposive sampling method. The time period used is from 2016 to 2020. The data is then processed using the multivariable regression method. The results of this study showed that the entire variable of the financial aspect had no influence on voluntary disclosure. Non-financial aspects show better outcomes with variables of board size and organization age having a positive impact on voluntary disclosure, while organization size has a negative impact. This research is based on limit sample, so it is not able to describe the actual situation. However the results are still meaningful for the organization, society, and government for making better transparency and accountability.

Pemanenan air hujan (PAH) merupakan cara yang digunakan untuk mengumpulkan dan menyimpan air hujan dari atap rumah, atap gedung atau di permukaan tanah pada saat hujan. Sebagai salah satu sumber air bersih, pemanfaatan air hujan dapat digunakan untuk mengatasi permasalahan kelangkaan air bersih, mengurangi volume air limpasan hujan dan mengisi kembali air tanah terutama di perkotaan. Pesatnya pertumbuhan penduduk di perkotaan memicu konsekuensi bahwa terjadi penurunan debit air tanah karena konsumsi yang berlebihan yang diperparah dengan pengurangan lahan tangkapan air hujan karena banyak lahan terbuka dikonversi menjadi areal bangunan.  Hal ini akan memicu terjadinya kelangkaan air tanah sekaligus memicu terjadinya banjir. PAH merupakan salah satu alternatif untuk  mengurangi terjadinya hal tersebut.  Dengan cara ini suplai air bersih dari PDAM  maupun dari air tanah dapat dihemat dan kelebihan airnya dapat diresapkan di sumur resapan sehingga dapat membantu pengisian kembali air tanah. Penelitian ini dilakukan selama tiga hari. Penampungan air dilakukan sekitaran dari pukul 15: 17 – 16:05 selama tiga hari. Jumlah air hujan yang dapat tertampung dalam sehari adalah 98 liter (0,098 m3). Sehingga jumlah air yang tertampung selama tiga hari adalah 0,098 m3 x 3 = 0,294 m3. Penampungan yang dugunakan pada penelitian ini adalah penampungan air dengan kapasitas 120 liter (digunakan untuk menampung air hujan) serta satu tendon untuk  sumur bor dengan kapasitas 1200 liter  yang menjadi sumber air kontrakan dan nantinya akan menjadi media tamping. Karena kebutuhan air bersih penghuni kontrakan dalam sehari adalah 0,48 m3
