Convergence of finite element solution of stochastic Burgers equation
Authors: Lv Jingyun , Lu Xiaoyan
Published: February 2024

We explore the numerical approximation of the stochastic Burgers equation driven by fractional Brownian motion with Hurst index $ H\in(1/4, 1/2) $ and $ H\in(1/2, 1) $, respectively. The spatial and temporal regularity properties for the solution are obtained. The given problem is discretized in time with the implicit Euler scheme and in space with the standard finite element method. We obtain the strong convergence of semidiscrete and fully discrete schemes, performing the error estimates on a subset $ \Omega_{k, h} $ of the sample space $ \Omega $ with the Gronwall argument being used to overcome the difficulties, caused by the subtle interplay of the nonlinear convection term. Numerical examples confirm our theoretical findings.
An approach to the global well-posedness of a coupled 3-dimensional Navier-Stokes-Darcy model with Beavers-Joseph-Saffman-Jones interface boundary condition
Authors: Tan Linlin , Cui Meiying , Cheng Bianru
Published: February 2024

This study focused on investigating the global well-posedness of a coupled Navier-Stokes-Darcy model with the Beavers-Joseph-Saffman-Jones interface boundary condition in the three-dimensional Euclidean space. By utilizing this approach, we successfully obtained the global strong solution of the system in the three-dimensional space. Furthermore, we demonstrated the exponential stability of this strong solution. The significance of such coupled systems lies in their pivotal role in the analysis of subsurface flow problems, particularly in the context of karst aquifers.

Presence can promote online learners' learning effectiveness in higher education, but in livestream teaching, the influential relationship between different types of presence and learning effectiveness is unclear. Therefore, based on the Community of Inquiry (CoI) Framework, we used structural equation, hierarchical regression, and the Bootstrap self-serving method to conduct a survey on college students participating in livestream teaching practice. The research findings revealed that livestream teaching substantially impacts learning effectiveness, with teaching presence, social presence, and cognitive presence all playing crucial roles. Notably, teaching presence has a significant positive influence on learning effectiveness through two key mediating factors: Social presence and cognitive presence. Consequently, three distinct mediating paths are identified. Among these three mediating paths, the most optimal route for teaching presence to enhance learning effectiveness is mediating cognitive presence. In conclusion, we recommend improving the livestream teaching environment, guiding learners toward active participation to promote a sense of embodiment, and elaborately designing livestream learning activities to improve interactivity. Finally, this paper offers evidence and insights for the improvement of livestream teaching in colleges, which will enhance learners' overall learning effectiveness.

Published: February 2024

For patients with limb motor dysfunction, the effect of physical exercise is directly related to their future quality of life. This article combines the physical training plan of rehabilitation therapists with the training of rehabilitation robots, which can effectively improve the training performance of existing lower limb rehabilitation robots. Therefore, a teaching and training method and a wireless data acquisition system based on energy acquisition wireless network sensor are proposed. Based on wireless wearable technology, wireless network sensors, PCs and electronic devices are used to monitor the activity information of human walking and standing in real time, and the physical fitness is tested by means of mean, variance, and standard deviation. Through the analysis of rehabilitation health, this article consists of two parts: power module and physical exercise. Finally, experiments show that the accuracy of wireless network sensors based on SVM algorithm is the most accurate under physical training. It provides a good means for wireless body area network technology.

Automated Digital Wind Instrument using Arduino UNO Microcontroller
Authors: Pamula Vinay Kumar
Published: February 2024

Recently, Blackstar Amplification Ltd. has introduced a Compact Carry-On Digital Wind Instrument (CDWI), mirroring the design of traditional recorder instruments in their size and shape. This CDWI can be played as a traditional wind instrument by blowing into the mouthpiece and simultaneously manipulating finger holes, enabling the production of desired musical notes. The main aim of this research work is the development of a prototype model to automate the CDWI, by utilizing the Arduino UNO microcontroller board and introducing the Automated Digital Wind Instrument (ADWI). The CDWI has a mouthpiece, nine finger holes, and one thumb hole, and the blowing mechanism can be automated by using a 12 Volts DC air blower and a servo valve. The author ingeniously develops a new servo valve using a plastic syringe, a ball, and a 5 Volts DC micro servo motor to regulate the air pressure blown into the mouthpiece. The ADWI fingers are meticulously crafted using plastic pen barrels, thrust tubes, and metallic springs to simulate the actions of a human music player's fingers. Positioned to maintain all finger holes in an open state by default, the selective closing of specific holes is achieved by ten micro servo motors to produce a specific musical note. In a preliminary test, the ADWI prototype is programmed to perform the Nursery Rhyme "Twinkle, Twinkle, Little Star." While evaluating the sound output by hearing, it is evident that the proposed ADWI effectively generates all the necessary musical notes. However, the noise generated by the air blower and micro servo motors introduces interference, impacting the clarity of the produced musical notes. Consequently, it is planned to integrate a noise reduction mechanism as part of future work.
Artistic Means and Therapeutic Effects in Sri Lankan Healing Rituals
Authors: Dona Lasanthi Manaranjanie Kalinga
Published: February 2024

Artistic expressions in the realms of mutually integrated sound culture and visual culture count as the essential elements of the traditional healing rituals in Sri Lanka. While music has a key role in the therapeutic process, visual ingredients provide the ritual setting with a glamour that exceeds the day-to-day domestic environment experience. Made for the occasion, a decorated ritual setting is the first sign to publicly announce the event and to create visual excitement. Its main aim is to welcome the invisible supernatural beings responsible for a disease. The sound produced by voices (chants, incantations, blessings, poetry, dialogues) and musical instruments (drums, handbells, hand cymbals, conch shells, anklets) aims to assure participation of community members and to act as a medium of connecting supernatural beings with the human world. Besides the visual and aural stimuli, the main roles in Sri Lankan healing rituals are given to unity thinking ,community caring, and community setup .Lessons learned from traditional healing rituals which integrate music, dance, visual arts, crafts ,and drama for the sake of individual comfort and the community’s wellbeing, have potential to benefit a variety of disciplines with a focus on artistic and/or therapeutic practices and outcomes such as medical and applied ethnomusicology and anthropology, psychomusicology, sociomusicology, visual arts, music therapy, including community music therapy and ethnomusic therapy, dance/movement therapy, psychotherapy, drama therapy, and more. The author’s arguments are expected to contribute to knowledge and understanding of holistic healing practices of Sri Lanka as non-pharmacological treatments marked by mutually interrelated artistic means and therapeutic effects.

In order to produce marketable yield, scientific methodologies must be used to forecast the greenhouse microclimate, which is affected by the surrounding macroclimate and crop management techniques. The MATLAB tool NARX was used in this study to predict the strawberry yield, indoor air temperature, relative humidity, and vapor pressure deficit using input parameters such as indoor air temperature, relative humidity, solar radiation, indoor roof temperature, and indoor relative humidity. The data were normalized to improve the accuracy of the model, which was developed using the Levenberg–Marquardt backpropagation algorithm. The accuracy of the models was determined using various evaluation metrics, such as the coefficient of determination, mean square error, root mean square error, mean absolute deviation, and Nash–Sutcliffe efficiency coefficient. The results showed that the models had a high level of accuracy, with no significant difference between the experimental and predicted values. The VPD model was found to be the most important as it influences crop metabolic activities and its accuracy can be used as an indoor climate control parameter.

Published: February 2024

The environment of a closed piggery is commonly characterized by spatial unevenness, and there are currently no specific standards for installation points of various environmental monitoring sensors. Therefore, the project team used the hanging track inspection robot (HTIR) as an environmental mon-itoring platform to seek the environmental monitoring points and ensure the scientific layout of moni-toring points. Ansys-CFD software was used to study the change rules of environmental parameters at 1.6 m (α plane), 0.7 m (β plane), and 0.4 m (γ plane) above the ground. The 300 monitoring points ((x1~x30) ×(y1~y10)) in each plane were analyzed to determine the most suitable monitoring points and inspection routes for HTIR. The results showed that: (1) All monitoring points could be arranged directly below the y3 track. (2) Monitoring points (x1, y3), (x10, y3) and (x30, y3) were environmental feature points. At (x1, y3), the maximum relative humidity and NH3 concentration on the α plane could be detected, and the maximum wind speed, maximum temperature, and maximum NH3 concentration on other planes could also be detected; At (x10, y3), the minimum temperature and maximum relative humidity of the β and γ planes could be detected; At (x30, y3), the maximum NH3 concentration in the α plane and the minimum relative humidity in all planes could be detected. This study scientifically arranged the inspection track and monitoring points for HTIR, improved the accuracy of environmental monitoring, and put forward suggestions for reducing NH3 concentration in closed piggeries, laying the foundation for the next step.

Since the Zika virus (ZIKV) pandemic in 2015–2017, there has been a near absence of reported cases in the Americas outside of Brazil. However, the conditions for Aedes-borne transmission persist in Latin America, and the threat of ZIKV transmission is increasing as population immunity wanes. Mexico has reported only 70 cases of laboratory-confirmed ZIKV infection since 2020, with no cases recorded in the Yucatán peninsula. Here, we provide evidence of active ZIKV transmission, despite the absence of official case reports, in the city of Mérida, Mexico, the capital of the state of Yucatán. Capitalizing on an existing cohort, we detected cases in participants with symptoms consistent with flavivirus infection from 2021 to 2022. Serum samples from suspected cases were tested for ZIKV RNA by polymerase chain reaction or ZIKV-reactive IgM by ELISA. To provide more specific evidence of exposure, focus reduction neutralization tests were performed on ELISA-positive samples. Overall, we observed 25 suspected ZIKV infections for an estimated incidence of 2.8 symptomatic cases per 1,000 persons per year. Our findings emphasize the continuing threat of ZIKV transmission in the setting of decreased surveillance and reporting.
Sociolinguistic aspects of the spoken version of Hausa in Ghana
Authors: Sadat Mohammed
Published: February 2024

Even though Hausa is not an indigenous Ghanaian language but it plays a very important role in Ghana’s sociolinguistics. It is the lingual franca for many people living in the zongos. Zongos are located in every major city in Ghana and they are occupied by different ethnic groups who use Ghanaian Hausa for their daily communications. Some popular and vibrant market centers in Ghana also use Ghanaian Hausa for their trading activities. However, there is no study that discusses both the features of Ghanaian Hausa and its social context. This explorative paper examines the current state of Hausa spoken in Ghana. It first discusses its historical and social contexts of use. Then, the paper examines its linguistic features in comparison with varieties of Hausa spoken outside Ghana (Nigeria) by drawing on data gathered from Ghanaian Hausa speakers and native speakers of Hausa who hail from Nigeria. The paper argues that Ghanaian Hausa is unique from the target Hausa from Nigeria, it is the first language for some residents in the zongos, it is widely used on some of the national televisions, radio stations and market centers, and it is the medium of instruction in the Islamic schools (makaranta). The paper proposes that the Hausa learnt and spoken in Ghana is best described as a Ghanaian Hausa because its peculiar features.
Cardinal numerals in Akan
Authors: Appah Clement , Duah Reginald Akuoko , Kambon Ọbádélé Bakari
Published: February 2024

This paper presents a Construction Morphology account of complex cardinal numeral formation in Akan (Kwa, Niger-Congo). Through a detailed description of the Akan numeral system, which is decimal, we identify various ranges of cardinal numerals and show that they share structures with other constructions in the language because they are either compounds or coordinate constructions. We show that, consistent with crosslinguistic patterns, the two arithmetic operations that underpin the construction of cardinal numerals in Akan are addition and multiplication and they are formally realised differently. While multiplication is achieved mainly through compounding (and reduplication), addition is expressed mainly through compounding and coordination. The Construction Morphology framework allows us to account for the full range of Akan cardinal numerals in a consistent manner, showing how numerals relate to other constructions in the language. We posit two constructional schemas for the two arithmetic operations, with various subschemas for different instantiating constructions, including some constructional idioms in which certain recurrent forms are pre-specified.

Published: February 2024

Intonation is one of the most problematic aspects of the English prosody for L2 speakers. Studies on Nigerian English (NigE) intonation have claimed that Standard English intonation differs significantly from native Englishes but studies on the interpretation and production of accentual intonation tunes of L2 acquisition have been rare. Fifty final-year university undergraduates from Nigeria (25 males and 25 females) were purposively sampled. Each of the respondents was given 10 English sentences to produce and interpret. Interpretations of each of the respondents was captured and converted to simple percentages while the voice production of each of the respondents was elicited from a Speech Filing System (SFS) installed on Hp250 laptop. Respondents' frequency of occurrence at production level showed appropriate use of 134 (26.8%) while inappropriate use amounted to 366 (73.2%) out of 500 expected results of accentual tunes. Production on gender basis revealed males and females appropriate use at 67 (13.4%) each and inappropriate use was 183 (36.6%) respectively, both sexes showing no difference in accentual tunes use. Findings revealed that out of the 500 expected results for interpretation of accentual tunes, respondents appropriately interpreted the English sentences in 360 (72%) instances while 140 (28%) respondents misinterpreted the English sentences. Though, results of respondents revealed competence in the interpretation of accentual tunes (72%) but at the production level, respondents did not apply accentual tunes (26.8%) on English expressions. This study concludes that Nigerian spoken English accent differs significantly from native Englishes and should be described as an outer circle English.

Analysing Infant Food Digestion through Artificial Neural Network
Authors: Luckyn B.J. , Orike S. , Gobo A. T.
Published: February 2024

The symbiotic relationship between nutrition and health is crucial, especially during the formative years of infancy when dietary intake has a significant impact on growth and development. New developments in food engineering highlight how important Artificial Intelligence (AI) is to the best possible optimization of baby food products, making them more inexpensive while maintaining great nutritional characteristics. The way that factors related to food processing affect an infant's ability to digest food and absorb nutrients has a big impact on their development and overall health. To evaluate the nutritional qualities of baby food products, this work elaborates on digestive models. It examines the three stages of digestive models static, semi-dynamic, and dynamic shedding light on the enzymes used in each stage and their corresponding benefits and drawbacks. The work also explores the theoretical developments in machine learning and adaptation and how they might be used to predict nutritional characteristics that are important for baby health. However, making use of Artificial Neural Networks (ANN) in a variety of food processing unit operations, this work will navigate the complex dynamics between food processing techniques and infant digestive stages. This method makes it easier to comprehend how food engineering and sophisticated computational models work together to forecast and maximize the nutritional benefits of foods designed specifically for infants. Fundamentally, the combination of cutting-edge food engineering methods and digestive modeling especially when it comes to baby food has great potential for guaranteeing that baby food offers are nutrient-dense and of high quality, both of which are essential for healthy growth and development.

Published: February 2024

This study deals with part quality concerning gate location on the part for injection molding. Through injection molding filling simulations, basic parameters such as injection pressure, bulk and surface temperature, shear rate, solidification, shrinkage, air entrapment, weld lines and others were analysed. The simulation was conducted on a fan blade model with Polycarbonate material. Polycarbonate is a commonly used polymer in the industry and is famous for its rigidity, strength-to-weight ratio and reliability in critical system. Simulation is done at six possible gate locations labelled A1 through A6. Injection molding filling simulations was performed to evaluate the performance of each gate location. Among the considered gate locations, gate A4 exhibited a considerably high pressure drop, while gate A5 exhibited a comparatively uniform pressure drop across the mould cavity, also gate A5 showed consistent and smooth filling along with uniform cooling implying less chance of defects. Gate A4 and A5 exhibit uniform distribution across the cavity in shear rate analysis. Gate locations A2, A3, A4, and A5 exhibited controlled solidification, indicating consistent part quality. However, Gate A6 exhibited problems with volume shrinkage, which requires process optimization. Gate A6 exhibited a significant reduction in air entrapment as compared to other gate locations.
ETNOGRAFSKA KARTA MILOŠA St. MILOJEVIĆA I NjENA VAŽNOST U 21. VEKU
Authors: Miletić Danilo
Published: February 2024

Miloš St. Milojević je pored poznavanja istorije i je- zika, bio je izvrstan kartograf. Karta koju je sastavio jedna je od važnih parametara sagledavanja prostora srpskog Tropolja koji je zauzimao srpski narod pre tek 149 godina (1873) i sledeće godine bliži se 150 godina od njenog nastanka što svakako treba obeležiti na određen način. Ova karta ide u prilog istraživanja dr Zorana Miloševića i potvrđuje tezu o nestajanju Srba koju Milojević pripoveda u ,,Odlomcima istorije Srba”. Šta se od onda desilo? Desilo se mnogo toga od Hercegovačke bune i Berlinskog kongresa, pa Majskog prevrata i konačno Velikog rata 1914. Posle toga dolazi period Jugoslavije i skretanja sa srpskog puta, na koji se tek postepeno vraćamo. Analizu ove karte usmerićemo u tri pravca. Prvi pravac pozabaviće se (anglo)germanskom tezom o doseljavanju Srba na Balkan i etničkim sastavom, drugi uspostavljanjem paralela između dva sveta cara Svevlada Prvog i Dušana Silnog, a treći pravac na geopolitiku karte iz (p)ogleda dr Milana Mladenovića. Na os- novu svega priloženog iznećemo zaključak o karti kao tapiji za sve srpske prostore i za sva vremena

U pametarnici srpskog naroda, istorijska prošlost je veoma zamršena, ali njoj dodatno doprinosi strano mešanje i uplitanje.

Milojević u svom naučnom amanetu ispravno zaključuje, kako jedini pravi odgovor na tumačenje imena Srbin može dati samo srpski jezik!
MILOJEVIĆEV ASAK U TROJADI
Authors: Bošnjak Ranko
Published: February 2024

U radu pod naslovom Milojevićevi Ksanti i Homerov Ksant, posebno priređenom za četvrti naučni skup posvećen Milošu Milojeviću, na temu Doprinos Miloša S. Milojevića istorijskoj nauci, pokazali smo kako se u njegovom bogatom naučnom opusu, čak i posle toliko godina, mogu pronaći činjenice koje mogu dati značajan doprinos novim saznanjima. Tim pre što se radi upravo o temama kojima se sam Milojević nije bavio, kao što je homersko pitanje u najširem mogućem smislu ili Trojanski rat. U ovom radu ćemo se ponegde i pozvati na po- menuti rad, ali samo na onim mestima gde su za oba rada korišćene iste činjenice, dok je u svakom drugom pogledu ovaj rad sasvim odvojen i bavi se isključivo pojmom istorijske Troje kao i neizbežnim Trojanskim ratom. Podsećamo da smo u prethodnom radu već definisali Homerovu i mitološku Troju kao odvojene entitete, iako smo obe pronašli na istoj geografskoj lokaciji i to na mestu današnjeg Feresa u dolini Marice. Upravo ta činjenica i jeste bila inicijalna kapisla za istraživanje koje je rezultovalo ovim radom, premda osnovna ideja autora, u početku, nije bila da ide dalje od Homera i Ilijade. Međutim, kako je istraživanje za- snovano na ovom epu dalo pomalo neočekivan i nadasve zanimljiv rezultat, prirodno je bilo nastaviti baš u ovom pravcu. Tako od tri Troje, defi- nisane u prethodnom radu, preostaje još samo jedna i to ona istorijska. Šta se o njoj može pronaći i da li možemo išta zaključiti o mestu ili oblasti gde se mogla nalaziti pokazaćemo u ovom radu, uz neizostavnu Milojevićevu pomoć. Držeći se upravo trojanske teme dopunićemo, onako usput, Milojevićevu kartu srpskih zemalja, prvenstveno u juž- nom delu Trakije. Tako ćemo dodati pomalo na Milojevićevu ispisanu i iscrtanu istoriju, a nastavljajući njegove radove odužićemo mu se na najbolji mogući način za svekoliki doprinos rodu i otečestvu!

Published: February 2024

This research highlights the impact of Variation Orders in construction projects, especially in the Tenjoresmi Area Arrangement. The results of the field study showed that the Variation Order caused significant changes to the Cost Budget Plan (RAB) and the performance of the implementing contractor. Some of the work affected includes changing the brand of air conditioner, replacing the amphitheater with a jogging track, dismantling railings, sanitary dismantling, plumbing dismantling, air conditioning dismantling, removing demolition debris, glass window frames, reinstalling aluminum door and window frames, wall handrails, doors. iron, disposing of excavated gravel, and planting shrubs. RAB analysis revealed changes in cost proportions for various works, such as increases in demolition and architecture and decreases in structures. In October and November, there was a delay in implementing the work due to a contract addendum, which was only approved in mid-October. However, the implementing contractor did not experience financial problems, and even experienced an increase in profit of 0.79%. In conclusion, Variation Orders can affect project time and costs, but flexible contractors can manage them well, and even optimize profits. Effective management is needed to cope with change and ensure the smooth implementation of construction projects.
Uptake of COVISHIELD vaccine and post-vaccination symptoms among healthcare workers at an academic primary care facility in Ghana.

Published: February 2024

Background: The emergence of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has affected health systems globally. Although a safe, effective, and widely accessible vaccine is crucial to ending the pandemic, the results of studies on the acceptability of vaccines among healthcare workers (HCWs) globally have been conflicting. Documented post-vaccination experiences are also limited. This study describes the uptake of the first dose of the COVISHIELD vaccine and analyses the pattern of post-vaccination symptoms among HCWs in Ghana.

Objective: This study sought to assess the uptake of the first dose of the COVISHIELD vaccine and analyse the pattern of post-vaccination symptoms among HCWs.

Methods: A cross-sectional survey was conducted at the Korle Bu Polyclinic/ Family Medicine Department (KPFMD) of the Korle Bu Teaching Hospital, Accra, in March 2021. Survey participants (n=188) were staff of the department who completed a structured questionnaire within one week of receiving their first dose of the vaccine. The vaccine uptake rate was estimated from those who received the vaccine (n=255) as a percentage of the total staff number at the department (n=314).

Results: The uptake rate of the first dose of the COVISHIELD vaccine among HCWs was 81.2% (n=255/314). The most frequently occurring post-vaccination symptoms were general malaise, headache, injection site pain and swelling, tiredness, muscle aches and fever. These symptoms were largely mild to moderate in severity and occurred mostly within 24 hours after vaccination. Of the 84.6% (n=159) respondents who reported at least one post-vaccination symptom, 77.4% (n=123) took analgesics to manage their symptoms. There was no significant association between age, sex, chronic health condition, a previous positive test for COVID-19 and experiencing post-vaccination symptoms.

Conclusion: A high proportion of HCWs received the COVISHIELD vaccine in this study. The study's findings are comparable with prior studies that indicated that the vaccine is generally safe and well-tolerated. Various stakeholders in Ghana should continue to educate, reassure and encourage the population to accept the vaccine as a key intervention towards containing the pandemic.

Background: Coronary artery disease is a significant cause of morbidity and mortality globally. Most people with coronary artery disease are asymptomatic, making its early detection with coronary artery calcium scoring using multidetector computed tomography an important aspect of its management.

Objective: Our study aimed to describe the spectrum of computed tomography findings (such as the absolute coronary artery calcium scores and coronary artery risk percentiles) and associated risk factors of 325 patients evaluated for coronary artery disease in Accra.
Methods: The study was a retrospective study involving retrieving electronically stored coronary artery calcium score reports for 325 patients reported by two radiologists. Patient information, including weight, blood pressure, and a history of diabetes mellitus and hypertension, were recorded. Data were analysed using Statistical Package for the Social Sciences version 23.Results: There were 62.2% (n = 202) males and 37.8%( n = 123) females. Of the total number, 44.6%(n = 145) had a normal coronary artery calcium score of 0, while 55.4%(n = 180) had values ranging from 1 to 2,690 (mean109.0±325.4). The two most prevalent modifiable risk factors for coronary artery disease recorded for individuals with coronary artery calcium score above 0 were an abnormality of weight (overweight and obesity)and hypertension in decreasing order. A significant relationship was observed between coronary artery calcium scoring and age (p = 0.001).
Conclusion: Our study showed that more than half of the participants had coronary artery calcification; abnormalities of weight followed by hypertension were the two commonest risk factors for CAD in Accra, and CAD occurred in individuals as young as 30 to 39 years old.

Background: Acute Respiratory Distress Syndrome (ARDS) is common in the Intensive Care Unit (ICU) setting and is associated with high mortality. Delayed diagnosis and failure to institute evidenced-based management have been associated with poor outcomes. Knowledge of the diagnostic criteria for ARDS and the adoption of recommended management practices by clinicians in the ICU is therefore required to reduce mortality.
Objective: This study sought to assess the knowledge and current management practices of ARDS among clinicians in a surgical ICU of the Korle-Bu Teaching Hospital.
Methods: This was a cross-sectional study involving a purposive sample of 15 clinicians (Specialist Anaesthesiologists) who work at the Korle-Bu Teaching Hospital Surgical ICU. A self-administered structured questionnaire was used to obtain data on the sociodemographic characteristics, knowledge and management practices of clinicians on ARDS. Clinicians' knowledge and management practices were scored based on conformity with the ARDSnet Ventilatory Protocol. Categorical data were
summarised as frequencies and proportions, and continuous data as Mean ± standard deviation.
Results: Clinicians (Specialist Anaesthesiologists) had good knowledge about ARDS (Mean knowledge score = 21.00±3.87),and their management practices were above average (Mean practice score = 8.53±2.50). The clinicians rarely (40%) or never (60%) practised prone ventilation.
Conclusion: Specialist Anaesthesiologists had good clinical knowledge of ARDS and applied appropriate management strategies. However, prone ventilation was rarely adopted

Background: Abdominal pregnancy, although a rare condition, has life-threatening consequences. This case report aims to expose the clinical and diagnostic challenges encountered in its management. We report a case of a 28-year-old gravida 2, para 1 woman, 35 weeks pregnant, who presented to Korle Bu Teaching Hospital with generalised abdominal pain and an ultrasound indicating a major-degree placenta previa. A repeat ultrasound assessment identified a viable abdominal pregnancy with the placenta attached to the uterine fundus. An emergency hysterectomy was done on account of a massive haemorrhage after the delivery of a live female foetus.

La fitoterapia es una práctica en la que se emplea el uso de plantas medicinales con fines curativos, la Organización Mundial de la Salud (OMS) refiere el concepto de fitoterapia, como una ciencia encargada del estudio de productos vegetales para su posterior utilización en la terapia de estados patológicos. Brosimum alicastrum Swarts (ábolrbol de Ramón) se considera históricamente, como un árbol con muchos beneficios, como para la elaboración de medicamentos y bebidas a partir de distintas partes del árbol, debido a que sus características fitoquímicas, sin embargo, al realizarse una encuesta (n= 81) en la comunidad de Bécal, ubicada en el estado de Campeche, al sureste de México, que tiene una población de aproximadamente 6801 según datos del INEGI, 2022., se observó que el 67 % de mujeres y el 31 % de los hombres  desconocen si B. alicastrum tiene un uso medicinal, esto debido a que el mayor porcentaje de participación se encuentra en el rango de edad de 15 a 24 años.  Destaca la presencia de un interés considerable, especialmente entre la población joven, en la importancia de este árbol, lo que sugiere la posibilidad de preservar y revitalizar el conocimiento sobre sus propiedades terapéuticas y tradicionales. Sin embargo, se evidencia una brecha de conocimiento significativa, particularmente entre las generaciones actuales, en lo que respecta a las propiedades medicinales y otros usos potenciales de esta planta. Además, el estudio revela que la recolección de forraje es el principal uso del Árbol del Ramón en la comunidad, lo que indica que las consideraciones económicas desempeñan un papel importante en la relación de la comunidad con esta planta. Esto abre oportunidades para desarrollar proyectos sostenibles que aprovechen el valor económico de esta especie, al mismo tiempo que se promueve su conservación y un uso respetuoso de sus recursos. En conjunto, estos hallazgos destacan la importancia de preservar y promover el conocimiento sobre el Brosimum alicastrum en Becal, beneficiando tanto a la comunidad como a la conservación de este recurso valioso.
Analisis Yuridis Isbat Nikah terhadap Status Hukum Anak Hasil Nikah Siri Berdasarkan Kompilasi Hukum Islam
Authors: Ardani Mochamad Fakhri Bimo , Suhadi Manan
Published: February 2024

Pengertian anak menurut Undang-Undang Nomor 23 Tahun 2002 tentang Perlindungan Anak adalah seseorang yang berusia di bawah 18 (delapan belas) tahun dan dimana Undang-Undang tersebut telah mengakui anak sebagai seorang individu yang berhak mendapatkan sebuah perlindungan, pemenuhan atas hak-haknya sebagai individu, dan memiliki tanggung jawab sesuai dengan usianya. Berbicara tentang anak pastinya tidak dapat lepas dari sebuah ikatan perkawinan, Karena setiap anak berasal dari sebuah perkawinan antara lawan jenis yaitu laki-laki dan perempuan. Ditegaskan di dalam Pasal 2 Undang-Undang tentang Perkawinan Tahun 1974 “Tiap-tiap perkawinan dicatat menurut peraturan perUndang-Undangan yang berlaku.” Tetapi pada kenyataannya banyak masyarakat Indonesia lebih memilih untuk melakukan perkawinan siri dimana perkawinan tersebut tidak dicatatkan sehingga berdampak negatif pada perkawinan dan terutama pada kedudukan dan status hukum anak dimana kedudukan dan status hukum anak hasil perkawinan siri tersebut tidak sama dengan anak yang berasal dari perkawinan yang sah karena perkawinan tersebut tidak diakui dan tidak memiliki akta nikah sehinnga pada anak tidak tercantum nama ayah dan hanya tercantum pada ibunya. Pemerintah telah memiliki solusi kepada pasangan suami isteri yang belum memiliki buku nikah atau bagi suami istri yang perkawinannya belum dicatatkan yaitu dengan melakukan Itsbat Nikah dimana tentunya Itsbat Nikah ini memiliki pengaruh yang baik untuk meringankan permasalahan yang dialami oleh pasangan dalam mencatatkan kembali perkawinan yang sudah dilakukan. Penelitian ini dilakukan bertujuan untuk menganalisis kedudukan status hukum dari anak Itsbat Nikah dengan status hukum anak yang sah. Metode penelitian yang digunakan dalam penelitian tersebut yaitu secara normatif dan penelitian hukum ini menggunakan metode pendekatan perundang- undangan (Statute Approach). Dengan dilakukannya Itsbat nikah maka terpenuhilah Pasal 2 Undang-Undang tentang perkawinan tahun 1974 dan perkawinan tersebut dicatatkan sehingga anak memiliki hak dan kewajiban yang sama dengan anak sah karena dicantumkannya nama ayah dan ibu di akta kelahiran anak tersebut dan statusnya menjadi jelas di mata hukum

Comparative analysis of peritoneal dialysis and hemodialysis for the management of kidney failure: A concise review
Authors: Khan Unsa , Siddiqui Mujtaba Azhar
Published: February 2024

Madam,
Chronic kidney disease has a high prevalence, affecting approximately 10-13% of the population. It is a chronic and advancing condition that carries an elevated risk of cardiovascular complications. In the early stages, patients often remain asymptomatic, Treatment options for chronic kidney disease include conservative management for patients with a glomerular filtration rate above 15 ml/minute, and replacement therapies like Hemodialysis (HD), Peritoneal Dialysis (PD), and kidney transplantation1.
Peritoneal dialysis involves solute and fluid exchange across the peritoneal membrane, utilizing diffusion, convective transport, and osmosis. Adjusting the flow rate of dialysis solutions optimizes solute and fluid removal, while various techniques enhance these transport characteristics. Peritoneal dialysis has advantages such as home-based therapy, ease of implementation, travel flexibility, lower cost, and suitability for specific patient groups. It allows continuous fluid and solute removal while preserving residual renal function. However, potential disadvantages include infection risks, limited dialysis adequacy, possible malnutrition, concerns about long-term viability, and psychological and fatigue-related issue2.
Haemodialysis is a widely used treatment for patients with acute and chronic renal failure, removing waste products through semipermeable membranes. It is commonly employed in medical emergencies like fluid overload and hyperkalemia, as well as various types of renal failure. However, haemodialysis demands substantial dedication and time from both patients and healthcare providers and may not be appropriate for all individuals with renal insufficiency. Treatment-related side effects include cramps, hypotension, issues with blood access, and reactions to dialyzer membranes. It should be noted that hemodialysis does not address the underlying disease but instead prolongs life and allows for the progression of multiple systemic conditions3.
The choice between PD and HD is crucial for patient outcomes. Studies on survival rates show mixed results, initially favoring PD due to residual renal function (RRF), but as RRF declines, there are potential risks. HD is generally preferred over PD for diabetic patients, with different risks of bone lesions. PD preserves renal function and improves quality of life as a home-based treatment. An integrated PD/HD program in dialytic centers provides comprehensive care for uremic patients4.
In conclusion, the selection between PD and HD depends on factors such as medical suitability, lifestyle, travel considerations, cardiovascular health, and resource availability. PD offers flexibility and independence, while HD can provide more efficient clearance of waste products and toxins from the body.
