Introduction: The type of admission to the Intensive Care Unit (ICU) influences the prognosis of patients with severe pneumonia and, in the case of patients with COVID-19 pneumonia, this is still unexplored. The objective of this study was to determine the differences between early and late ICU admission.
Methodology: A retrospective cohort study of patients with COVID-19 pneumonia at two high-complexity hospitals in Colombia. Early ICU admission (EICUA) was defined as direct admission from the emergency department or within the first 24 hours of admission. Late ICU admission (LICUA) was defined as admission from the hospitalization service after 24 hours of arrival. A robust Cox regression was performed for the variable recovery time, to determine the impact of the ICU admission type in the hazard rate.
Results: 68.2% were EICUA patients and 31.8% were LICUA patients. Recovery and duration of hospital stay were significantly lower in EICUA than in LICUA (9 vs 15 days, p = 0.0001, and 10 vs 15.5 days, p < 0.0001, respectively). However, the duration of ICU stay (7 vs 9 days, p = 0.131) and the invasive mechanical ventilation requirement (48.9% vs 54.9%, p = 0.374) were not statistically significant. The 30-day follow-up showed no difference between the EICUA and LICUA (alive 97% vs 94.6%, p = 0.705).
Conclusions: Mortality between EICUA and LICUA patients with COVID-19 pneumonia showed no statistically significant differences. However, the recovery time, the probability intensity of instant recovery, and the duration of hospital stay were better in EICUA than in LICUA. Neither EICUA nor LICUA affects the final status (death) of patients.

Introduction: The annual incidence of brain abscesses is 1–2% in developed countries and up to 8% in developing countries. Our aim was to describe the profile and etiological agents of patients with surgical brain infections according to their nosological diagnosis on admission, and to analyze whether the initial diagnosis influenced the neurological deficit at discharge.
Methodology: This was an observational study with convenience sampling. All surgical cases operated between January 2017 and February 2022 with a final diagnosis of an infectious process were included. Three groups were analyzed according to admission diagnosis: a) infection, b) neoplasia, and c) miscellaneous. The time before admission, final histological diagnosis, etiological agent, length of hospital stay, and secondary neurological deficits were investigated. Descriptive and comparative statistics were used.
Results: 24 cases, including 18 (75%) men and 6 (25%) women, of ages 19 to 61 years (average 43.7 years) were studied. Nosological diagnoses on admission were infection in 9 (37.5%) patients, cerebral neoplasia in 9 (37.5%) patients, and miscellaneous diagnoses in 6 (25%) patients. Among the miscellaneous, neoplastic, and infectious groups, 33.3%, 33.3%, and 22.2% of patients were discharged with some neurological deficits with overall neurological morbidity and mortality of 29.6% and 8%, respectively. The etiological agents were Mycobacterium tuberculosis (16.6%), Streptococcus sp. (13%), Morganella morganii (8.7%), Nocardia sp. (4.3%), Cryptococcus sp. (4.3%), and Klebsiella sp. (4.3%).
Conclusions: Nosological diagnosis on admission did not influence the percentage of patients with neurological deficits in our study. Mycobacterium was the most frequent etiological agent.

Published: October 2024

Introduction: Cases of human infection with Hymenolepis diminuta are very rare, and only a few hundred cases have been described. We report a rare case of H. diminuta infection in a 16-month-old boy living in a rural area of Bac Giang province, Vietnam.
Case presentation: The patient was admitted to the hospital with mild diarrhea, abdominal pain, and several tapeworm segments in his stool, and no other symptoms. The worm was identified as H. diminuta by morphological examination of eggs in a concentrated stool specimen and genetic sequencing of the 18S rRNA gene of the worm. The patient was successfully treated with single oral dose of praziquantel, and he fully recovered.
Conclusions: This report presents a rare case of human infection with H. diminuta in Vietnam; and contributes to enhancing our understanding of the epidemiology, clinical manifestation, and treatment protocols of human hymenolepiasis.

Published: October 2024

Introduction: The study aimed to compare the outcomes of nirmatrelvir and ritonavir drug combination (Paxlovid) therapy in patients who received treatment within or after five days of COVID-19 confirmed in the elderly.
Methodology: This was a single-center, retrospective cohort study of older COVID-19 patients (≥ 60 years) admitted from April 7 to May 30, 2022. Patients were categorized into the EP group (starting Paxlovid within five days) and the LP group (starting Paxlovid after five days) following symptoms onset. Length of stay and positive SARS-CoV-2 duration were compared between the two groups. Severe case conversion from mild and moderate COVID-19 patients were also analyzed.
Results: In total, 273 patients were included: 137 in the EP group and 136 in the LP group. Compared to the LP group, the EP group had a significantly shorter length of stay (12.4 vs. 14.7 days, p = 0.001) and positive SARS-CoV-2 duration (11.7 vs. 15.8 days, p < 0.001). The EP group had lower severe case conversion (4.4% vs. 15.4%, p = 0.002). Additionally, abnormal IL-6 and lower lymphocyte count indicated increased length of stay. Older age was associated with a decreased risk in SARS-CoV-2 negative test (HR = 0.98) and an increased risk in severe case conversion (OR = 1.11).
Conclusions: Starting Paxlovid within five days of COVID-19 symptoms onset reduced the length of stay and SARS-CoV-2 duration compared to initiating treatment after five days. While severe case conversion among mild COVID-19 patients might be comparable whether starting Paxlovid within or after five days.

Published: October 2024

Introduction: Coronavirus disease 2019 (COVID-19) has an extremely high infection rate. This study aimed to investigate emotional states and COVID-19 infection of medical workers during the self-management strategy to COVID-19.
Methodology: Questionnaires were collected via an online questionnaire platform from 20 December 2022 to 19 January 2023, including demographic characteristics, number of vaccine doses, COVID-19 test results, occupation, attendant situations of workers, clinical symptoms, disease duration, and the Depression, Anxiety and Stress Scale 21.
Results: A total of 748 complete questionnaires were collected. The average age of participants was 33.61 ± 8.94 years, and 79.55% participants were female. The proportion of anxiety was significantly higher in the infection group (52.32%) than in the non-infection group (28.45%) (p < 0.001), as was the proportion of stress (41.47% vs. 31.90%, p = 0.046). Medical students (odds ratios (OR) 0.54, 95% confidence interval (CI) 0.31–0.93) and other staff (OR 0.63, 95% CI 0.40–0.98) had a lower risk for depression than doctors (p = 0.024), and attendant and infective situations of workers was the risk factor for depression (p = 0.007). Occupation (p = 0.029) and infected workers (p = 0.001) were related to anxiety. Infected attendant workers had a higher risk for stress (OR 1.97, 95% CI 1.12–3.48) than uninfected attendant workers (p = 0.019).
Conclusions: Most medical workers infected with COVID-19 had emotional disorders during the COVID-19 pandemic. Attention and useful measures are suggested to support medical workers.

Introduction: Since COVID-19 first surfaced in 2019, it has seriously threatened public health. The most prevalent symptoms are respiratory ones. This study aimed to present the correlation between the severity of the clinical presentation of the disease and the results of respiratory function tests conducted within 6 months after hospital discharge.
Methodology: This retrospective study included 99 patients with confirmed SARS-CoV-2 virus infection. Of all patients 24.2% had accentuated bronchovascular pattern, 9.1% had unilateral, and 29.3% had bilateral pneumonia. In comparison, 35.4% patients had diffuse changes, which were described as acute respiratory distress syndrome (ARDS) on computed tomography (CT).
Results: Patients with unilateral, bilateral pneumonia or diffuse lung damage had significantly lower forced vital capacity (FVC) values. They were treated with non-invasive mechanical ventilation (NIV) or invasive mechanical ventilation (MV) and had lower FVC values (0.039). A negative, weak correlation existed between CT findings during the infection and Diffusing capacity for carbon monoxide (DLCO) measured after the infection (0.003). A negative, weak correlation was found between oxygen therapy, the use of NIV, and MV findings during the infection with DLCO. A negative correlation was noted between leukocyte values during the infection and forced expiratory volume in the first second (FEV1) and FVC after the infection.
Conclusions: Patients with COVID-19 infection who need oxygen support and MV continue to suffer from loss of respiratory function after the resolution of COVID-19 infection. These findings highlight the negative predictive value of pulmonary tests in the long-term follow-up for the development of PC-ILD as well as decreased pulmonary capacity.

Authors: Kareem Ali Maryam , Shia Jaafar Sataar
Published: October 2024

Introduction: Parvovirus B19 virus-mediated viral inflammation and immune-complex deposition generate mainly short-term manifestations in the affected individuals. The objective of this study was to determine Parvovirus B19 infection in rheumatoid arthritis (RA) patients.
Methodology: The study employed 50 patients diagnosed with RA and 30 healthy individuals. Blood samples were collected from both groups. The blood samples were screened for Parvovirus B19 infection using polymerase chain reaction to detect B19 DNA and enzyme-linked immunosorbent assay to detect anti-B19 IgM and IgG.
Results: 17 (34%) of 50 patients tested positive for parvovirus B19 DNA. In contrast, the mortality rate in the control group was significantly lower (6.7%; p = 0.005). Anti-B19 IgG antibody levels differed significantly with patients and control (p = 0.007), whereas anti-B19 IgM Ab levels did not (p = 0.6). There was a significant correlation between viremia B19 and all measured parameters. Parvovirus-affected patients had significantly higher CRP and ESR, elevated DAS28 scores, and more joint pain compared to parvovirus (-) patients.
Conclusion: Anti-CCP and RF values were significantly high in parvovirus (+) patients. Joint erosion was also prevalent in patients who tested positive for parvovirus. The findings of this study suggest that infection with parvovirus in patients with RA, and a possible role of this viral infection in the pathogenesis of RA may contribute to the pathogenesis of RA.

Introduction: Identifying inflammation and lung damage markers is crucial in reducing morbidity and mortality of coronavirus disease 2019 (COVID-19). This study aimed to examine the validity and reliability of severity and post-infection lung damage and analyse their relationship.
Methodology: This was a prospective analysis study at the Airlangga University Hospital, Surabaya, Indonesia, from March to August 2021. The infection`s severity was measured by examining angiotensin-converting enzyme 2 (ACE2) levels and complete blood count. Lung damage was estimated by reviewing Krebs von de Lungen (KL)-6, matrix metalloproteinase (MMP)-9, tissue inhibitor metalloproteinase (TIMP)-1, and MMP-9/TIMP-1. Two-factor confirmatory factor analysis (CFA) and canonical correlation were calculated using Lisrel and SPSS (version 25).
Results: The research sample included 76 patients. The t count loading factor values were calculated: ACE2 (6.00), neutrophils (-0.80), lymphocytes (-0.63), neutrophil-lymphocyte ratio (NLR, 1.27), eosinophils (-1.52), basophils (1.72), monocytes (0.05), platelets (0.53), leukocytes (-0.51), platelet-lymphocyte ratio (PLR, -1.15), KL-6 (10.47), MMP-9 (11.91), TIMP-1 (11.79), and MMP-9/TIMP-1 (-0.24). The t values were: neutrophil covariance error (6.11), lymphocytes (6.12), NLR (6.10), eosinophils (6.08), basophils (6.07), monocytes (6.12), platelets (6.12), leukocytes (6.12), PLR (6.10), ACE2 (0.97), KL-6 (5.63), MMP-9 (2.08), TIMP-1 (2.77), and MMP-9/TIMP-1 (6.12). t value canonical correlation of 7.04 (t count > 1.96) indicated a correlation between the severity of the patient and post-infection lung damage.
Conclusions: The severity was adequately measured through ACE2, IL-6, IL-10, neutrophils, lymphocytes, leukocytes, and NLR. Lung damage was measured with KL-6, MMP-9, and TIMP-1. There was a correlation between disease severity and lung damage.

Learning Terrain Traversability for a Mobile Robot based on Information Fusion
Authors: Peralta-Lopez José Eleazar , Antonio Emmanuel , Becerra Israel , Barranco-Gutierrez Alejandro-Israel , Murrieta Rafael
Published: October 2024

In this work, we propose an approach to determine terrain traversability for a car-like robot. Our approach has two main modules: a neural network classifier that makes use of sensors' readings to assign traversability levels to control inputs of the robot, and a second neural network that, based on the outputs of the first network, mimics the control selection performed by a human driver. The approach incorporates sensor fusion from a variety of sources to enhance the traversability estimation, and it is trained employing a semi-supervised learning scheme with examples resulting from the interaction of the car with the environment. This semi-supervised scheme avoids exhausting manual labeling and is built on the premise that there is a correlation between the terrain traversability and the required and observed behaviors of the vehicle. The method is validated with data obtained from a physical electric car.
ALHK: Integrating 3D Holograms and Gesture Interaction for Elementary Education
Authors: Hakeem Abeer , Bitar Hind , Alfahid Ayman
Published: October 2024

The integration of technology in elementary education offers innovative ways to enhance learning. One such advancement is the use of three-dimensional holograms (3DH), which provide immersive displays that merge seamlessly with the learner’s environment, creating a dynamic and engaging atmosphere. Educators have found that 3D visual tools significantly improve student comprehension, with 94.4% agreeing in a preliminary study. However, using interactive 3D holography alone has limitations, such as the inability for students to physically touch or manipulate holographic objects. To address this, Active Learning with Holo-Kid (ALHK) is introduced as a desktop application for elementary school students (grades 1 to 6). ALHK combines Leap Motion technology’s precision with interactive 3D holography to overcome these limitations. The combination allows students to interact with virtual objects in a more immersive and realistic manner. Holograms provide visual representation, while Leap Motion enables precise gesture recognition and hand tracking, resulting in a seamless and intuitive user experience. Initial evaluations demonstrate improved student engagement and comprehension. Future iterations aim to enhance scalability by incorporating features like custom object upload, multi-user interaction, and broader age applicability. ALHK shows promise as a tool for creating an immersive and intuitive learning environment using 3D holograms and interactive technology in elementary education.

In this work, we present a disciplinary e-tutoring system that integrates ONTO-TDM, an ontology designed for teaching domain modeling, with advanced transformer technology. Our primary objective is to enhance semantic similarity tasks within the system by fine-tuning a Sentence Transformer model. By carefully adjusting training parameters with a curated dataset of question-answer pairs focused on algorithms and data structures, we achieved a notable improvement in system performance. The Sentence Transformer model, combined with domain ontology, achieved an accuracy of 91%, a precision of 93%, a recall of 89%, and an F1-score of 90%, significantly surpassing the results of existing works. This methodology highlights the potential to deliver personalized support and guidance in tutoring scenarios. It effectively addresses the evolving needs of modern education by offering tailored answers and reducing the necessity for constant learner-tutor interaction, thereby improving the efficiency of educational support systems.
Armut verstehen
Authors: Schildbach Ina
Published: October 2024

Um Armut zu bekämpfen, scheint es naheliegend, mehr Geld zu fordern: mehr Geld in Gestalt von Sozialstaatsausgaben, für Entwicklungshilfe etc. Nur: In Zeiten der Klimakrise kann darin nicht die zentrale Lösung für das nach wie vor drängende Problem der nationalen und weltweiten Armut liegen. Was folgt daraus? Natürlich nicht, dass wir Menschen und Staaten das Recht auf Entwicklung absprechen. Unsere exklusiven und exkludierenden Privilegien aufgrund der Zufälligkeit des Geburtsortes lassen sich nicht rechtfertigen. Dennoch ist diese Erkenntnis der Nicht-Verallgemeinerbarkeit relevant. Sie verdeutlicht, dass wir prinzipiell anders über das Phänomen Armut nachdenken müssen. Hierzu möchte dieses Buch einen Beitrag leisten.

This research is driven by a fundamental recognition of the pivotal role played by water infrastructure in shaping urban environments, particularly within post-colonial settings. Focusing on the transformative period from 1957 to 1985 in Penang, marked by significant governance and societal changes, our objective is to comprehensively analyse the development of post-colonial water architecture. By identifying key factors influencing the design, implementation, and outcomes of water infrastructure projects, we aim to shed light on both successes and challenges faced during this era. Our motivation lies in extracting valuable insights from historical experiences to guide contemporary policymaking and scholarly efforts, with a specific emphasis on enhancing functionality, efficiency, and sustainability. Employing a history methodology encompassing historical analysis, archival research, and case studies, this research aims to provide a nuanced understanding of post-colonial water architecture in Penang, contributing to the broader goal of fostering efficient, sustainable, and aesthetically pleasing water infrastructure for improved urban living. This study found that the evolution of water infrastructure during this period in Penang was not merely a response to increasing urbanisation, but was intricately linked to policy decisions, technological advancements, and societal dynamics. One significant discovery pertains to the impact of governance changes on the efficiency and effectiveness of water projects. The shift in governance structures influenced decision-making processes, project implementations, and overall outcomes in the realm of water architecture.

Change cannot be separated from education and science, followed by rapid technological developments influencing human attitudes and behaviour in daily activities, including organisational behaviour and leadership patterns. More research is needed related to the trilogy leadership and organisational training support. Researchers state that trilogy leadership has a positive effect on organisational training support, and some say it does not affect organisational training support. Objective: This research examines and analyses the influence of the sustainability trilogy leadership pattern on green performance with the moderating role of dynamic exploration capabilities as a perspective of belief in local wisdom on state-owned companies in Indonesia. The object of research on employees of state-owned enterprises was as many as 260 respondents in Yogyakarta. Purposive sampling was used to take samples using a questionnaire. The data collected were carried out through three tests: data test, model test, and hypothesis testing using AMOS. Findings indicate that the trilogy leadership significantly positively affects organisational training support and dynamic exploration capability. Organisational training support has a significant positive effect on dynamic exploration capability, and dynamic exploration capability has a significant positive effect on green performance. Limitations and future research are also discussed in this study.

Utilisation of fisheries resources requires good management to maintain the sustainability of fish resources. Based on these conditions, this study aims to analyse the status of fish resource utilisation and estimate fish catches in the following year. The data collection is secondary data from Prigi Fishery Port, East Java, from June to September 2023. This study evaluates biological surplus production relationships. Next, due to the time series data, the forecasting performance uses Holt-Winter’s exponential smoothing. The modelling shows that the best estimation value in the Fox model is based on the highest R2 (0,614) and the effort coefficient (0.000034). The maximum sustainable yield (CMSY) and the optimum catch effort (EMSY) values were 10.006 tonnes/year and 29,425 trips/year, respectively. It shows that biological overfishing has yet to occur. The average production forecasting results in 2021-2023 decreased 8.5% from the previous year. Forecasting fish catches in 2021 exceeds CMSY, but in 2022 and 2023, production is still below CMSY. The circumstance indicates that fishing operations are inefficient because the catch obtained is projected to be smaller with fixed effort. Possible management strategies, therefore, include creating sustainable fisheries management through improved work variation for fishers in the off-season.

Oil palm biomass, which includes empty fruit bunches (EFB), mesocarp fibres (MF), palm kernel shells (PKS), and palm oil mill effluent (POME), are no longer seen as low-value residue, but as valuable economic resources that may contribute positively to national wealth. These oil palm biomasses can be converted into high value-added products, which can in turn generate additional revenue for the country. This study aims to identify the current biomass utilisation by palm oil mills in Peninsular Malaysia and examine the economic viability of biomass products generated by these mills across different categories. This study uses primary data obtained through a census of all 242 Malaysian Palm Oil Board-licensed palm oil mills in Peninsular Malaysia. The data were analysed using descriptive analysis and independent samples t-test. The study found that incineration is the most profitable approach for EFB, followed by selling EFB to other parties. However, due to environmental regulation and the lack of market for EFB, most of the resources (62.4%) were either returned to plantations or sent to landfills. In addition, 92.4% of MF generated were utilised for electricity generation through in-house boilers and this alternative has been proven to provide maximum profit to palm oil mills. The study also found that although selling PKS to other parties was proven to provide better profits to the palm oil mills, the PKS were mostly utilised for electricity generation through in-house boilers. Lastly, for the sludge from POME, there was no significant difference in the utilisation of the sludge, either if it was used for plantations or sold to other parties.

The purpose of this study is to examine the structural relationship between destination image, event quality, tourist satisfaction, and tourist loyalty in the context of Madurese cultural arts performances in Sampang Regency, especially those held at Lon-Malang Beach, Toroan Beach and Camplong Beach. The proposed structural model relationship between variables was tested using structural equation modeling with data from 190 respondents utilizing the bootstrapping method. The study findings show a direct correlation between event quality and destination image with the level of tourist satisfaction during their visit to tourist loyalty. There is evidence that tourist satisfaction fully mediates the relationship between destination image and tourist loyalty. This study emphasizes the importance of including event quality in the tourism destination model, and shows that events such as Madurese cultural arts performances are an integral part of a marketing plan aimed at improving destination image, tourist satisfaction, and tourist loyalty.

Authors: Ahmed Yasir , Din Marium
Published: October 2024

This study analysed the classroom management challenges faced by novice Elementary School Teachers (ESTs) who joined the Federal Directorate of Education (FDE), Islamabad, in 2022. The physical, administrative and individual challenges of the classroom were studied. Using a quantitative approach, the research focused on 661 ESTs, consisting of 249 males and 412 females. A stratified sample of 248 teachers (95 males, 153 females) was selected, and data were collected via a self-developed questionnaire. Experts confirmed the instrument’s validity and reliability were measured with a Cronbach’s alpha of 0.885. Data analysis revealed that novice teachers face several challenges, including limited classroom space, insufficient furniture, and inadequate resources for science labs. They also face challenges in maintaining discipline, disruptive behaviour, and irrelevant questions from students. Furthermore, individual differences among students due to varying IQ levels, learning interests, and socio-economic backgrounds proved challenging. Overcrowded classrooms hinder novice teachers' ability to focus and provide individual attention. The study concluded that heads of educational institutions must offer consistent guidance and support to newly appointed ESTs, especially during their first year, to improve classroom management skills.

Today, data security is a critical component of the efficient performance of every organization's diverse requirement, one of the important requirements is to provide a secure connection for data transmission in organization's networks. Cryptography algorithms are used to protect transmitted data from unauthorized access. Every day, a great deal of research is being done. The process of encrypting data is currently under development. Therefore, a substantial technological or research effort is still required. Cellular networks and secure communication. This proposal calls for the development of a new encryption system based on Using random keys in all the rounds. That’s mean we generated random keys as 128 bits for each round and save it in an array with size (8×8) because we have 8 rounds and each key divided into 8 sub keys as 16 bits for each to use in encryption and decryption. The developed random keys and traditional algorithm keys were tested with statistical tests of NIST, which made up a comparison and conclusion that the developed keys have a higher randomness specially in linear complexity, Frequency within block and random excursion tests, which leads to a better quality of encryption. Then we could test the cipher text with frequency within block test that was evaluated by (0.49590998713105255) and the approximate entropy test that was evaluated by (0.4922198616875501) for each cipher text which resulted from standard and modified Kasumi algorithm that’s means we can conclude that our modified Kasumi algorithm achieved more secure data in its resulted cipher text.
Investigation of Copper Anodization Products with Temperature and Chemical Solution Changes
Authors: Hashim Mustafa , Salih Haitham
Published: October 2024

The rapid breakdown anodization (RBA) process was used to modify the copper surface and produce copper oxide powder. The effects of the temperature and inhibitors like glycerol and ethylene glycol were studied. The rate of corrosion increased dramatically at low temperatures, whereas it decreased at high temperatures. Cubic Cu2O particles were formed on the anode. Their volumes increased with increasing temperatures. Scanning electron microscope (SEM) images show the production of semispherical particles in the powder formed at low temperatures, but these particles congregate and combine at high temperatures. After using the glycerol, octahedron and semispherical Cu2O particles were formed on the anode and cathode, respectively. The findings confirm the concept that the anodizing process's temperature may be utilized for controlling the oxide to metal ratio. Significant slowing of the anodic process occurs at high ratios for both inhibitors.

Published: October 2024

The density and height of the ionospheric F2 layer affect the observation of Jupiter's radio signals. The study aims to determine an approximate observation threshold from the values of the F2 peak density and the height of the F2 peak. The Florida and Lamy stations in the USA were selected. Utilizing actual observation data of Jupiter's radio signals from the Radio JOVE Data Archive for the years 2014-2015. The Radio Jove Pro software was employed to predict radio emissions from Jupiter. Ionospheric data were sourced from the International Reference Ionosphere (IRI) website. The primary focus of this study is to examine the role of the ionosphere in blocking the radio signals emanating from Jupiter. It was found that 49% and 31% (for the Florida and Lamy stations, respectively) of the predicted radio emission events from Jupiter were not observed. The likelihood of observation is higher after sunset and depends on Jupiter's elevation above the horizon relative to the observer. The F2 peak density during nighttime and throughout the year ranged from approximately 1011 to 1012 m-3 at altitudes of about 260-360 km. 89% and 98% (for the Florida and Lamy stations, respectively) of the observations occurred when the F2 peak density was less than around 6×1011 m-3. In contrast, 80% and 56% (for the Florida and Lamy stations, respectively) of the cases of non-observation occurred when the F2 peak density was greater than approximately 6×1011 m-3. As for The height of the F2 peak (hmF2), 85% and 93% of the observations occurred when the hmF2 was greater than about 300 km for the Florida and Lamy stations, respectively. The probability of observation is significantly influenced by the relationship between the electron density and its corresponding altitude.

Published: October 2024

Abstract
In this article, we use the Sinc approximation to solve the single Poisson problem (where the first derivative or higher order does not have an exact answer on the border of the boundary). We have examined the Sinc Galerkin approximation to solve the single Poisson problem, and finally, to solve the Poisson problem, we will use the sinc collocation method and in this method, we will reach a linear system. By carefully choosing the length of the steps and the number of nodal points, we will solve this system with two methods, with the orthogonalization technique, a numerical approximation will be obtained. Its accuracy can be exponential and of order  where  is a transaction parameter and c are a constant independent of N. In the final part, we will give some numerical examples of single Poisson problems.

MANAGING CORPORATE CLEANING OPERATIONS WITH A FLUTTER-DEVELOPED MOBILE APP: MAXIMIZING EFFICIENCY WITH THE CLEANER APP
Authors: Özkurt Cem
Published: October 2024

This study introduces a mobile application designed to streamline and supervise institutional operations. The application facilitates seamless coordination for cleaning staff and supervisors. At our university, cleaners used to mark their tasks on paper to prove completion, but this method did not allow for tracking cleaning durations and details. To address these issues, we developed an application that offers a new approach to institutional digital transformation for monitoring cleaning tasks. The application is programmed in Flutter, with a Firebase database, and allows for the recording of task start and completion times, providing managers with a transparent overview. Cleaners access and complete tasks via the user interface, while managers monitor activities, track progress, and generate daily reports through the management interface. A key feature of the application is its ability to archive historical data, allowing managers to access past records and gain insights into operational trends. Additionally, the capability to export reports in PDF format offers accessibility and ease of sharing. The evaluation of the application was conducted by examining data from the Cleaning Services Monitoring Unit under the University's Administrative and Financial Affairs Department. The examined data comprises 280 days and includes 33,587 records. By meticulously recording task start and completion times, the application provides managers with a transparent overview for analysis and evaluation. According to the data from the Cleaning Services Monitoring Unit, the application has increased efficiency by 23% and reduced task completion times by 28%. As a result, cleaners have been able to complete an additional task each day. This demonstrates that the application enhances functionality and makes operations more efficient.
