Authors: Mohammed Musa , Muhammad A.G. , Kamaludeen Mustapha , Bayel Haruna Sallau
Published: April 2024

The radiation from different types of radionuclides has both advantages and disadvantages. However, detailed research reveals that the  drawbacks of several radionuclides far outweigh their advantages, particularly in regions with high concentrations, posing alarming  impacts on human health. The study focuses on assessing outdoor background radiation levels in Jimeta and Yola towns, Adamawa State, Nigeria. Using a well-calibrated portable halogen-quenched Geiger Muller (GM) detector at 20 locations, measurements were taken at an  elevation of 1.0m above ground level, with GPS tracking for accurate location. The research evaluates radiological health hazards and  radiation effective doses to different body organs based on outdoor background exposure rates. Comparison with recommended permissible limits reveals that mean values for outdoor background exposure levels (0.016 mRh-1) and absorbed dose rates (147.46  nGyh-1) exceed safety limits (0.013 mRh-1, 84.0 nGyh-1) set by UNSCEAR and ICRP. The total excessive lifetime cancer risk (ELCR) ranged  from 0.33× 10−3 to 2.61× 10−3 , with a mean value of 0.78 × 10−3 , close to the world average lifetime cancer limit (1.45× 10−3 ). Despite the mean annual effective dose equivalent (AEDE) (0.2219mSvy-1) being below the recommended limit of 1.00 mSvy-1 for general public  exposure, and effective doses to various body organs remaining below 1.0 mSvy-1, the study indicates potential long-term health hazards  such as cancer due to accumulated doses. Generally, the study shows that Jimeta and Yola Metroplis is relatively safe  radiologically with little contamination which could be attributed to the geological formation and partly due to human activity such as  market and car park for transport system in the area. However, the contamination will not pose any immediate radiological health effect  on resident of the area but there is tendency for long –term health hazards in the future such as cancer due to doses accumulated. It is  therefore recommended that regular radiation monitoring exercise should be conducted on the area from time to time in order to  checkmate both the workers and the members of public from high radiation exposure.

This research assessed the plant species composition, distribution and International Union for the Conservation of Nature (IUCN)  conservation status of plants in University of Uyo botanical garden and arboretum using systematic sampling technique. The species  were sampled in 10 x 10 m quadrats spaced at least regular intervals of 20 m from each quadrat. Thirty-one and thirty-eight species were encountered in the arboretum and botanic garden respectively. In terms of the frequency, Chromolaena odorata and Nauclea diderichii  had the highest values (75%), while Acanthus montanus, Anthocleista djalonensis, Anthonotha macrophylla, Baphia nitida, Barteria  nigritiana, Carpolobia lutea, Ceiba pentandra, Cnestis ferruginea, Entandrophragma utile, Hura crepitans, Lonchocarpus griffoneonus, Rauvolfia vomitoria, Senna siamea, Tamarindus indica, Tectona grandis and Treculia africana had the least frequency (25% each). For the  density, Nauclea diderichii had the value of 250±15.30 st/ha. In the botanic garden, Ageratum houstonianum, Alchornea cordifolia,  Chromolaena ordorata and Croton hirtus had the highest frequency (100%) while Allamanda cathartica, Asystasia gangetica, Bambusa vulgaris, Caladium bicolor, Centrosema virginianum, Cnestis ferruginea, Culcasia scandens, Cyathula prostrata, Desmodium scorpiurus,  Emilia sonchifolia, Heliconia psittacorum, Ipomea involucrata, Lagenaria sphaerica, Mimosa pudica, Nephrolepis bisserata, Panicum sp.,  Pentaclethra macrophylla, Plumeria rubra, Polyalthia longifolia, Pteridium aquilinum, Scoparia dulcis, Senna siamea, Sesamum radiatum  and Sida acuta had the least frequency (33.33%). The vegetation of both sites indicated variation in composition of trees, shrubs, herbs,  climbers and ferns. These heterogeneities may be a pointer to their varying adaptation levels and differential responses of plant species  to pedological and anthropogenic influences.

Published: April 2024

Radon in potable water has turned out to be an issue of public health concerns, specifically when used immediately from supply for  domestic purpose and consumption without any pretreatment. In this study, 222Rn Concentration in 15 water samples collected from  ground water sources (borehols) in Katagum local government Bauchi State was determined, using Liquid scintillation counter (Tri-Carb- LSA1000) and the radiological risk was calculated. The study revealed that, 222Rn concentration ranges from 28.44 to 49.61 Bql-1 with  mean value of 39.55 Bql-1. These values were found to be higher than the permissible limits set by WHO, USEPA and UNSCEAR. The mean  value of annual effective dose due to ingestion for different age categories (adults, children and infants) are 0.29, 0.43 and 0.51 mSvy-1  respectively; and for inhalation the mean is 0.1 mSvy-1. Also, the mean value of excess life cancer risk due to ingestion for different age groups (adults, children and infants) are 0.0010, 0.0015 and 0.0018 respectively while that of inhalation is 0.0003. Thus, this study reveals  that borehole water around Katagum Local Government Area Bauchi State is not radiologically safe and there is need for constant  monitoring.

Published: April 2024

This paper gives an insight into the need for radiation detection and the most commonly flexible and efficient radiation detector. It also  examines bulk characteristics of 4H-SiC semiconductor radiation detector with Ni and Ti as metals for the contact. Bulk characterization of  the device, including: doping concentration, electrons and holes behaviors, space charge and current densities were carried out. The modeling is conducted using Sentaurus Technology Computer Aided Design (TCAD) to examine charge transport in bulk 4HSiC material.  Data obtained were further analyzed through Sentaurus visual, sentaurus Techplot and Excel to clearly determine the characteristics of  the device. It is observed that when the semiconductor and metal are in contact, the Fermi-level is established where the doping concentration varied with either magnitude of the doping concentration or nature of the dopant. Similarly, Schottky and ohmic contacts  and temperature effect were observed from the device characteristics which demonstrate that, the detector can withstand a temperature  from the range of 100K to 700K in no fluctuating state.

Authors: Olomi J.E. , Muhamedhussein M. , Haonga B.T.
Published: April 2024

Background: The Surgical Implant Generation Network (SIGN) Fin nail is a relatively newer design of intramedullary nails that eliminates  the requirement for distal locking. While various factors influencing treatment outcomes with different nail designs have been extensively  studied, limited research has focused on the specific implications of using the SIGN Fin nail.
Objective: This study aimed to assess the relationship between Fin nail canal fitting and treatment outcomes in femur fractures treated  with the SIGN Fin nail at Muhimbili Orthopaedics Institute.
Methods: A cross-sectional study was conducted at a tertiary hospital in  Tanzania. Patients who underwent femoral fracture fixation with SIGN Fin nails between January 2016 and December 2021 were recruited  from the SIGN surgical database. Radiographic measurements were performed using radiant software, fracture union at one year was  assessed using the mRUST score, and weight-bearing status at 6 weeks was obtained from patient records.
Results: The mean canal  diameter was 11.30±1.75 mm, and 82.2% had a canal fill of 80% or more. The reoperation rate was 5.9% (7/118). Although not statistically  significant, patients with canal fill less than 80% had a higher rate of reoperation (p = 0.074). The union rate was 84.1% in this study, with a mean mRUST score of 9.4, and those patients with a canal fill of less than 80% were more likely to have nonunion at 1 year (p = 0.028).  Pain on weight bearing at 6 weeks was reported by 42.9% (24/118) of participants, and this was significantly associated with canal fitting  (p < 0.001).
Conclusion: The study found the degree of canal fitting of the Fin nail to be an important factor affecting the outcomes of  femoral fractures treated with SIGN Fin nails. A higher degree of canal fill was associated with better pain outcomes and lower nonunion  rates.

In this study, styrene was used as a functional monomer for the production of molecularly imprinted polymer (MIP) via free radical  polymerization method, using bromocresol green dye (BCG) as template. A non-imprinted polymer (NIP), that excluded the template,  was also synthesized. Both polymers were applied for the removal of BCG from aqueous medium. The synthesized polymers were  characterized with Fourier transform infrared spectroscopy, scanning electron microscopy, and X-ray powder diffraction spectroscopic  techniques. The effect of operating variables, such as pH, contact time, initial dye concentration and process temperature, on the efficiencies of the polymers in removing the dye were evaluated. Equilibrium time of BCG adsorption onto the  MIP was reached within  40 min, with adsorption capacity of 49.68 mg g-1 . The adsorption process followed the pseudo-second-order kinetic and Freundlich  isotherm models, while chemisorption mechanism was predicted. The adsorption process was spontaneous and exothermic in nature,  with DH values of -140.03 and -25.01 kJ/mol-1 recorded for BCG removal by MIP and NIP, respectively. The styrene-based MIP showed  good mechanical stability, and retained up to about 99% of its adsorption capacity after six sequential cycles of   regeneration.  Comparatively, the MIP (99.81mg g-1 ) performed considerably better than its NIP (59.00 mg g-1 ) analogue in the removal of BCG from  aqueous medium, thus affirming the potentials of the molecular imprinting technique in the production of efficient adsorbents for  adsorption of toxic dyes from industrial effluents.

Advances in the biological synthesis of nanoparticles have attracted decisive research attention in recent years. This is due to their eco- friendliness, nontoxicity and large spectra of applications. In this work, the structural characteristics and the purity of biogenic zinc oxide  (ZnO) nanoparticles were assessed. Zinc oxide (ZnO) nanoparticles were synthesized extracellularly using the culture filtrate of  Aspergillus niger, in the presence of zinc acetate dihydrate, as a precursor. The structural characteristics and purity of the nanoparticles  were examined using standard characterization methods viz UV-visible spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM), Fourier-transmission infrared (FT-IR) spectroscopy and X-ray diffraction (XRD). Results revealed a peak at  311nm and whitish and spherical particles with particulate sizes between 30 and 40 nm for the UV- -1 visible spectroscopy and SEM  respectively. On the FT-IR scale, absorption peaked at 548 cm in the spectra region known for the functional groups of ZnO nanoparticles;  while the average crystalline size was 21 nm based on XRD analysis. Findings in this study revealed that the ecofriendly  biogenic nanoparticles synthesized by common fungi, such as Aspergillus niger, possess desirable qualities comparable to those from  non-ecofriendly and costly chemical processes, which are currently employed for an array of applications.

Published: April 2024

According to the World Health Organization, fluoride in drinking water, either below or above the established permissible range, can adversely affect oral health, including tooth decay and dental fluorosis. The objective of this study was to evaluate fluoride and chloride ion concentration and their health implications in groundwater within Bwari Area Council, Abuja, Nigeria using ion-selective electrode potentiometric titration for fluoride ion and Argentometric titration for chloride ion determinations. The results showed a high fluoride concentration in well water samples ranging from 0.126 mg/L to 0.216 mg/L, compared to borehole water samples ranging from 0.013 mg/mL to 0.052 mg/L. Among the chloride concentrations, the highest levels were observed in the well water sample A (96.09 mg/L), followed by borehole samples, A (63.08 mg/L) and B (49.35 mg/L). The lowest chloride concentration was recorded in the borehole sample H (11.82 mg/L). Notably, both well and borehole water sources in the studied communities had fluoride concentrations below the established minimum WHO standard (0.5 mg/L). The chloride concentrations in the groundwater samples from the study area fell within WHO standards (< 250 mg/L). The results from this study suggest that the continuous consumption of water from these community sources, without additional sources of fluoride, may increase the risk of tooth decay. Therefore, addressing this issue and ensuring appropriate water treatment measures is vital for maintaining optimal oral health in the region.
Arsenic Species Distribution and Toxicity in the Environment, Bioaccumulation, Biomethylation and Bioremediation by Microalgae: A Review
Authors: Obuekwe I. S. , Ajuzie C. U.
Published: April 2024

Arsenic (As) is a noxious metalloid that has been designated a priority pollutant and is present in the environment as a consequence of both anthropogenic and natural processes. Its toxicity in environmental and biological systems depends strongly on the chemical species. Interest in arsenic and microalgae interactions is important because microalgae are at the base of the aquatic food chain, are used in animal nutrition and has potential for As phytoremediation. This paper reviewed the current information on As species distribution in the environment especially as it relates to its toxicity to microalgae as well as its bioaccumulation, biomethylation and bioremediation by microalgae using appropriate methods. Information obtained revealed that Microalgae have evolved mechanisms for dealing with As in the environment with arsBHC operon mediating the reduction and extrusion of arsenite from the cells. They accumulate large amounts of arsenic from their surroundings which could lead to toxicity, As excretion from cells, reduction, methylation or complexation with metal binding peptides like glutathione and phytochelatins. This has made them suitable as ecological indicators to give an indication of As bioavailability and also in possible applications for the process of As remediation. Microalgae are been proposed for bioremediation purposes in aquatic environment since they show a high capacity for biosorption and bioconcentration of As and most importantly since they are able to methylate inorganic As to non-toxic organic and volatile As.

Palm Nut Cracker Machine is mainly needed for the Palm Nut seeds. Palm Nut is very hard in nature and very tough to break manually with hand; hence in industrial production of palm oil a palm nut cracker machine that is able to break the palm nuts into the small pieces is usually necessary. Therefore, the objective of this paper was to fabricate a palm nut cracking machine and evaluate its performance of cracked nuts parameters as influenced by cultivars using standard methods. Data obtained shows that optimum crack efficiency of 97% was obtained at shaft speed 2600 rpm dura cultivar of 8% MCdb, 7 kg feed weight, 91% crack efficiency was obtained for tenera cultivars at 6% MCdb and 5 kg feed weight at the same shaft speed, while, crack efficiency of 87% was observed for pisifera cultivar at 6% MCdb, feed weight of 7 kg and operational speed of 2200 rpm. Optimum kernel breakage ratio % of 14.66, 21.93, and 17.24 % occurred at the experimental cracking of palm nuts dura, tenera and pisifera cultivars with corresponding feed weights 7, 5 and 6 kg, respectively. On weightier feed rates and shaft speeds, crack efficiency of machine was higher for the oil Palm nuts cultivars at lower moisture content.

Published: April 2024

Fermented Parkia biglobosa seeds (iru) contain high protein content, serving as a major source of protein in rural areas, among people who cannot afford animal proteins. Spices are known to possess health benefits in humans. Hence, this study assessed the impacts of spices such as alligator pepper, ginger, garlic, nutmeg, turmeric, grains of Selim, cocoplum and skinplum on the microbial population and physicochemical properties of fermented Parkia biglobosa seeds. A 30g of each spice was added to 300g of previously pressure cooked and dehulled locust beans in separate containers. Each was sterilized and inoculated with Bacillus subtilis. All the samples including control (naturally fermented P. biglobosa alone) were fermented at 370C for 36h. The microbial load, pH, total titratable acidity (TTA) and proximate analysis were determined. Commercially fermented iru had the highest microbial load of 5.40, with unfermented iru having the least load (4.78). Unfermented iru had the least pH (6.35), the pH of all fermented samples was significantly high (P=0.05) with values ranging from 7.27 to 8.29. TTA of all the samples varied with the highest value of 5.75 recorded in cocoplum fermented iru while Selim fermented iru had the least value (0.85). Protein and fat contents of all fermented samples significantly increased (P=0.05) while carbohydrate and crude fibre contents decreased. Selim fermented iru had the highest ash content of 6.07 while alligator fermented iru had the least ash content (2.86). This research confirmed that fermentation of P. biglobosa with edible spices improved its nutritional value in production of iru.

Published: April 2024

Abuja Municipal Area Council (AMAC) is experiencing rapid urban expansion, which is expected to impact land surface temperatures (LST). This paper evaluates the trends in soil adjusted vegetation index (SAVI), normalize difference buildup index (NDBI), and land surface temperature (LST) between 1987 and 2023 in AMAC using Landsat 4 Thematic Mapper and Landsat 8 Operational Land Imager/Thermal Infrared Sensor imagery, respectively. Results show that in 1987, SAVI ranged from -0.126 to 0.477, NDBI from -0.186 to 0.678, and LST from 27.18 to 46.4 oC. In 2023, SAVI ranged from -0.253 to 0.71, NDBI from -0.308 to 0.619, and LST from 23.89 to 46.57 oC. Analysis showed an increase in vegetation in 2023 compared to 1987. Built-up and bareland areas became more concentrated in the northeast in 2023 compared to 1987, and temperature reductions were observed in areas with increased vegetation, notably in the south and southwest. Correlation analysis indicated a strong negative relationship (-0.772) between SAVI and LST in 1987, weakening in 2023 (-0.389). NDBI and LST remained moderately positively correlated (0.645 in 1987, 0.621 in 2023). Significant differences (P<0.01) were observed between 1987 and 2023 SAVI, NDBI, and LST values. These findings have important implications for environmental monitoring, and urban planning in rapidly urbanizing areas such as AMAC

Authors: Asuzu-Samuel H. O.
Published: April 2024

Aluminium pervades ecosystems, posing a nuanced risk of intoxication for both animal and human cohorts.  In this paper, cardioprotective and haematological effects of wonderful kola (Buchholzia coriacea) in Wistar rats exposed to aluminum chloride-induced toxicity was investigated by different methods including haematological analysis revealed significant decreases in PCV, HB, RBC, and PLT, with increased WBC in the aluminum chloride-induced group, indicating hematological toxicity (p < 0.05). Vitamin C partially restored parameters, while both low and high doses of Wonderful Kola extract showed positive effects, suggesting potential protection against aluminum chloride-induced toxicity (p < 0.05). Histological assessment demonstrated severe inflammation in the aluminum chloride-induced group, partial protection with vitamin C, and potential protective effects with Wonderful Kola, especially at higher doses. Wonderful Kola extract exhibited protective effects on cardiac tissue histology in aluminum chloride-induced toxicity, highlighting its potential as a therapeutic agent. These results contribute to the understanding of the potential therapeutic benefits of natural products in mitigating cardiovascular diseases. Further research on natural remedies for cardiovascular diseases is warranted, and caution should be exercised when considering treatments that may have detrimental effects on cardiac structure.

BackgroundPatient waiting time as an important indicator of quality of services has been along-standing concern in health care.ObjectiveThe aim of this study was to assess patient waiting time in primary health caresettings in Rwanda.MethodsThis was a mixed-method study design. In quantitative phase, Patient Flow TimeLog was used to track the time patients spent waiting for the service. On exit,a structured questionnaire was administered. Observations were conducted tocapture information regarding the flow and processes. In qualitative part, six focusgroup discussions with patients were conducted. Semi-structured interviews withhealthcare providers were held.ResultsAmong 410 participants, the majority were females (77.1%). The overall healthcentre level waiting time was 211 minutes (3.5 hours). To receive a service, patientswaited an average of 81.5 minutes (1.4 hours). Three conceptual themes wereidentified: a) reported sections to have long wait time; b) causes of long waitingtime; and c) needs for activities to spend time on as patients wait.ConclusionMost patients experienced prolonged waiting times during their visit to the primaryhealth care settings , and the major factors were the huge number of patients, fewhealthcare providers, and lack of medical equipment. To effectively address thesechallenges, more resources and personnel must be allocated to primary healthcaresettings to help foster a higher level of client satisfaction with minimal primaryhealthcare waiting time.Rwanda J Med Health Sci 2024;7(1):6-21

BackgroundBasic life support (BLS) refers to a package of care that first responders provide toanyone experiencing a life-threatening condition to increase the victim’s chanceof survival. Globally, 92% of people who had out-of-hospital cardiac arrest dieddue to limited provision of BLS, therefore, there is a need to assess the awarenessand attitude of the general public towards BLS, such as taxi drivers.MethodsA quantitative, analytical study that involved 327 drivers recruited from threedifferent bus stations in Kigali city was undertaken and binary logistic regressionwas used for statistical analysis.ResultsThe current study found that 19.5% of company bus drivers were aware of basiclife support, and 29% had a positive attitude. However, none of the participantshad a basic emergency kit in their buses. Having basic life support training,(AOR=7.853:95%CI: 1.326-10.413) and previous involvement in accidents(AOR=4.321:95% CI 1.163-4.628) were significantly associated with basic lifesupport awareness.ConclusionKigali city in collaboration with Rwanda Utilities Regulatory Authority need todevise ways bus drivers can be trained in basic life support. In addition, there isa need for every bus permitted to work in transportation sectors to get a basiclife support kit.Rwanda J Med Health Sci. 2024;7(1):36-45

BackgroundAntenatal care (ANC) helps ensure the best health conditions of the mother and foetus during pregnancy. However, achieving optimal ANC attendance and adherence to the World Health Organization (WHO) recommendations remains a global challenge, with significant disparities in attendance rates. A qualitative study was conducted exploring pregnant women's perspectives of various enablers to their attendance and adherence to recommended ANC visits in Rwanda. MethodsThis exploratory qualitative study involved 22 pregnant women attending ANC in four public health centres in the Eastern province, of Rwanda. An interview guide with semi-structured questions was used to gather information about the moderators of ANC attendance and adherence among pregnant women. Data were audio-recorded and transcribed verbatim, and thematic analysis was used to categorize themes under the five-level Social Ecological Model (SEM).ResultsEarly recognition of pregnancy, financial stability, and female participation in decision-making were identified as intrapersonal enabling factors of ANC attendance and adherence; spousal support was identified as an interpersonal enabling factor; community health workers, and community relationships as community enabling factors; availability and cost of ANC services as institutional enabling factors; and media campaign, community outreach as public policy enabling factors contributing to the pregnant women's attendance and adherence to ANC visits.ConclusionEnablers at multiple levels affect women’s attendance and adherence to ANC visits. It is essential to consider each level when implementing effective strategies to maximize ANC attendance and adherence to the WHO recommendations in order to improve maternal- foetal well-being in Rwanda.Rwanda J Med Health Sci. 2024;7(1):101-115

The long-spined sea urchin Diadema setosum is an algal and coral feeder widely distributed in the Indo-Pacific that can cause severe bioerosion on the reef community. However, the lack of genomic information has hindered the study of its ecology and evolution. Here, we report the chromosomal-level genome (885.8 Mb) of the long-spined sea urchin D. setosum using a combination of PacBio long-read sequencing and Omni-C scaffolding technology. The assembled genome contains a scaffold N50 length of 38.3 Mb, 98.1% of complete BUSCO (Geno, metazoa_odb10) genes (the single copy score is 97.8% and the duplication score is 0.3%), and 98.6% of the sequences are anchored to 22 pseudo-molecules/chromosomes. A total of 27,478 gene models have were annotated, reaching a total of 28,414 transcripts, including 5,384 tRNA and 23,030 protein-coding genes. The high-quality genome of D. setosum presented here is a valuable resource for the ecological and evolutionary studies of this coral reef-associated sea urchin.

A CASE STUDY IN ASRIGDARA WITH SHODHANA AND SHAMANA CHIKITSA
Authors: Joshi Apurva , Sharma Rashmi
Published: April 2024

Introduction: Asrigdara is a condition commonly encountered by physicians in day-to-day practice. It is a preva-lent medical condition in women that can lead to significant physical and emotional disturbances. Asrigdara is characterised by excessive discharge of Asrik (menstrual blood). Abnormal uterine bleeding encompasses both cyclic and non-cyclic bleeding patterns.
Acharya Charaka has elaborated on various causative factors such as Ati Lavana (excessively salty), Amla (sour), Guru (heavy), Katu (pungent), Vidahi (spicy), Krushara (dry), Payasa (milk), Saktu (wheat), Mastu, which can aggravate Vata, and cause retention of Rakta vitiated due to the reasons above. This, in turn, can lead to an increase in doshas affecting the Rajovaha Sira (uterine vessels) and subsequently increase raja (menstrual blood). The fundamental treatment principles involve normalising the amount of menstrual flow and addressing associated symptoms. A 30-year-old married female patient presented to the outpatient department (OPD) with complaints of prolonged menstruation duration, excessive menstrual flow, and lower abdominal pain. The pain was described as erratic, accompanied by generalised weakness. To address the goal of reducing excessive menstrual blood loss and regulating the menstrual cycle, a combination of Ayurvedic treatments was employed, including Shodhana Chikitsa (detoxification) through Virechana Karma and Shamana Chikitsa (palliative treatment) using Shalmali Ghrita. The desired outcome of the Ayurvedic intervention was to alleviate heavy menstrual bleeding and establish regularity in the menstrual cycle. Conclusion: - Heavy menstrual bleeding not only inflicts significant mental stress but can also impede a woman's ability to engage in physical activities, causing disruptions in her daily routine. Prolonged and cumbersome menstrual cy-cles over the long term can even lead to life-threatening conditions. Therefore, the required treatment should be pure, non-hormonal, practical, safe, and gentle, aiming to restore the menstrual and ovulatory cycle without symptom recurrence and any adverse effects on long-term usage.

Published: April 2024

Traffic flow prediction is crucial in transportation management and optimizing control strategies and infrastructure planning. However, traditional prediction methods often need help handling traffic data's inherent uncertainty and complexity. This paper explores the application of Grey prediction models as a promising approach for efficient traffic flow prediction. Grey prediction models, rooted in Grey systems theory, offer a robust framework for modelling systems with incomplete and uncertain information. The paper provides a comprehensive overview of Grey prediction models, including the Grey Verhulst, Grey-Markov, and Grey differential equation models. It discusses the process of data collection, pre-processing, and model application in traffic flow prediction. Case studies and experimental results demonstrate the effectiveness of Grey prediction models in accurately forecasting traffic flow patterns. Despite challenges such as data sparsity and model complexity, Grey prediction models offer significant advantages over traditional methods, including improved prediction accuracy and adaptability to dynamic traffic conditions. The paper concludes with recommendations for practitioners and researchers interested in leveraging Grey prediction models for efficient traffic management.
delimitación de funciones entre las distintas clases de personal
Authors: Gamero Casado Eduardo
Published: April 2024

La delimitación de funciones entre las diferentes clases de personal viene provocando conflictos de gran envergadura en la ordenación del empleo público. La línea divisoria entre funciones reservadas a funcionarios públicos y empleados laborales no es clara en el art. 9.2 TREBEP. La confusión reinante obedece en gran parte a la polisemia del concepto de potestad administrativa, que se delimita por el Tribunal Supremo con una amplitud mayor de la que se atribuyó a este precepto cuando se aprobó en 2007. La Ley 5/2023, de Función Pública de Andalucía, hace un esfuerzo por delimitar claramente las funciones de cada clase de personal, en una apuesta valiosa, alineada con el Derecho estatal y acorde con el concepto de potestad administrativa en el alcance que actualmente se infiere del Ordenamiento jurídico.

Authors: David David , Zahra Amalia
Published: April 2024

Player churn is a prevalent challenge in the gaming industry. Most predictions of player churn utilize private datasets that are not easily accessible to the public. This study aims to investigate the performance of Logistic Regression, Random Forest, Support Vector Machines, and Ensemble Learning models using a dataset from a public API for predicting player churn, in comparison to other studies that typically rely on private game logs. In this research, the dataset consists of 418 unique player IDs, with a churn rate of 15%. After training the models, it was found that Logistic Regression and SVM achieved an accuracy of 95%, Random Forest achieved an accuracy of 96%, and Ensemble Learning, with Neural Network as the meta-learner, achieved an accuracy of 92%. These results underscore the validity of using public API data as an alternative data source for predicting player churn.
