Published: September 2023

Introduction:
We aimed to analyze the association between the consumption of sexually explicit media (SEM) in the sexual practices of Brazilians and the exposure to HIV infection.

Methods:
This is an analytical, cross-sectional national study, conducted with 854 participants. Data were collected from September 2021 to January 2022 and analyzed in SPSS.26 software using the Logistic Regression model, with a robust estimator for the covariance matrix.

Results:
In the results we observed that 558 (65.3%) participants revealed the habit of watching SEM; of these, 58.2% saw up to two scenes per day. The increased chances for involvement in sexual practice of greater exposure to HIV were identified in: being male (ORa=1.36 times); having a homosexual, bisexual, asexual, or pansexual sexual orientation (ORa=1.44); habit of watching SEM or erotic art (ORa=1.47); and being under the age of 12 at the first contact with SEM (ORa=2.74). As such, we can observe that the consumption of sexually explicit media is associated with sexual practices of greater exposure to HIV among Brazilians.

Conclusion:
Therefore, the development of public policies and strategies to prevent practices aimed at the consumption of sexually explicit media becomes relevant, starting with the demonstration of HIV prevention strategies during the sex scenes.

Authors: Raut Samali S. , Singh Neha R. , Rane Bhushan R. , Jain Ashish S. 
Published: September 2023

Background:
Benzoyl peroxide is a peroxide with antibacterial, irritating, keratolytic, comedolytic, and anti-inflammatory properties. When benzoyl peroxide is applied topically, it breaks down and releases oxygen, which kills the germs of Propionibacterium acnes. Benzoyl peroxide's irritating impact causes an increase in epithelial cell turnover, which causes the skin to peel and aids in the healing of comedones. Treatment for acne vulgaris involves the use of benzoyl peroxide.

Objective:
The research is aimed at studying the formulation of Microsponge gel preparation of benzoyl peroxide by using Carbopol 934 as a gelling agent and evaluation of microsponge gel formulation for its physicochemical properties.

Methods:
Microsponges of Anti-acne agent benzoyl peroxide drug were prepared by quasi-emulsion method, and in-vitro drug release using a suitable membrane model using a simple diffusion cell.

Result:
Prior to drying, the microsponge was filtered and rinsed using distilled water. Formulation containing benzoyl peroxide and Eudragit RS100 with a ratio of 1:4 showed a high 87.5% drug content and 78.20 % yield. The drug content of the microsponge gel was found to be 84%. Microbiological study on S. aureus was conducted by the cylinder cup method and found good results. The in-vitro diffusion of microsponge formulations was sustained for 8 hours. The drug release rate for Eudragit RS-100 was reported to be 88.87% after 8 hours based on the polymer: drug ratio (4:1).

Conclusion:
The quasi-emulsion solvent diffusion method was used to successfully prepare benzoyl peroxide microsponges using Eudragit RS100, Ethyl Cellulose, and HPMC K4M as polymers. The formulations with the highest medication concentration were made with the porous polymer Eudragit RS100.
Decolourisation of Metal-azo Dyes in Wastewaters by Sodium Peroxodisulphate: A Template for Experimental Investigations
Authors: Cheung Philip C.W. , Williams Daryl R. , Kirk Donald W. , Murphy Pamela J. , Barton Stephen J. , Barker James 
Published: September 2023

Background:
It has long been recognized that the presence of azo metal complex dyes and their non-complexed counterparts in wastewaters, which is due to their manufacturing and use in the textile industries, renders natural waterways intensely coloured, and is therefore aesthetically unacceptable. Azo dye moieties are also known to be precursors of human carcinogenicity.

Objective:
This work aimed at the decolourisation of metal-azo dyes present in wastewaters so that pollution of natural bodies of water can be prevented. Decolourisation is indicative of the destruction of the metal-ligand complex, allowing the retrieval of transition metal ions, which are also water contaminants. Fracturing of the azo bond itself minimizes the potential for the carcinogenicity of these dyes.

Methods:
Decolourisation is achieved by the oxidative action of free radicals furnished by Na2S2O8, the sodium salt of peroxodisulphuric acid (Marshall’s acid). Raman spectroscopy characterizes the dye (ligand) known as “Eriochrome Black T (EBT)” by a peak at 1425 cm-1. Dismantling of its molecular structure by peroxodisulphate will lead to decolourisation accompanied by the collapse of the peak. Concomitantly, as EBT ligands fracture and cease to chelate, metallic ions are released, oxidized to a higher oxidation state, and precipitated as insoluble compounds in alkaline media.

Results:
The concentration of metallic ions in the aqueous phase has been found to be substantially reduced. The successfully treated dye solutions are mostly clear and colourless; their Beer-Lambert absorbances are in the range of 0.02 ≤ absorbance ≤ 0.05. The treatment of Ni(II), Co(II) and Fe(II)-EBT solutions is straightforward; the Cu(II) and Cr(III)-EBT solutions require additional treatment to be included in the above absorbance range. The Cr(III)-EBT is the least responsive to treatment. Fracturing of the azo bond is evinced by Raman Spectroscopy.

Conclusion:
A template to investigate the feasibility of decolourisation of metal-complex dye solutions is pioneered and recommended.

Published: September 2023

Background:
The term artificial intelligence refers to the use of computers and technology to
replicate intelligent behaviour and critical thinking similar to that of a human being. In COVID-19, artificial intelligence has been widely applied in diagnostics, public health, clinical decision-making, social
control, treatments, vaccine development, monitoring, integration with big data, operation of additional
vital clinical services, and patient management. Hence, we conceptualized this study to evaluate the usage
of artificial intelligence as a tool at the time of the COVID-19 pandemic.

Methods:
From December, 2019, to May, 2022, all clinical trials using AI approaches listed on clinicaltrials.gov and ctri.gov.in were examined and analysed.

Results:
Out of 8072 studies on COVID-19 listed on ClinicalTrials.gov and 674 studies on the CTRI
website, 53 studies were related to AI. Ten (18.9%) of the 53 studies were interventional, while the remaining 43 (81.1%) were observational.

Conclusion:
With limited medical resources and growing healthcare strain, the introduction of AI approaches will increase human efficiency and capacity to combat the COVID-19 pandemic. In this review,
artificial intelligence was proven to be more accurate than human specialists in COVID-19 diagnosis and
medication discovery.

The prevalence of obesity continuously increase, as are associated comorbidities and healthcare expenses. Early detection, intervention, and effective treatment of obesity are important to improve quality of life and to reduce costs. This Community Practice Program aimed to evaluate health status and provide education about healthy life style of people at productive age in Pajimatan Hamlet, Imogiri, Bantul, Yogyakarta. Participants were 66 adults (26 men, 40 women) aged 19-64 years living in Pajimatan Hamlet. The program was held on November 2021. Education on healthy life style was done using WhatsApp group. Pre- and post-test were given to the participant before and after the education. Health screening was done by measuring height, weight, waist circumference (WC), blood pressure BP), and fasting blood glucose level. Obesity was determined using body mass index (BMI) and WC. There were significant increase scores before and after education in men (p= 0.017) and women (p< 0.001). Health screening indicated that men were significantly taller (p< 0.001) and heavier (p= 0.009) than women, however, there was no difference in BMI, WC, BP, and fasting blood glucose level (p> 0.05). There were no differences in the distribution of BMI obesity between men and women, however, women with central obesity were higher than men (70% women, 30% women, p= 0.021). Men having prehypertension were higher than women (46.2 vs. 15%), on the other hand, women with hypertension I and II seemed to be higher than men (p= 0.043). The prevalence of type-2 diabetes was slightly greater in women (12.5%) compared with 7.7% in men. In conclusion, the Community Service Program found high prevalence of obesity and hypertension in the population. Education on healthy life style program can help to improve knowledge of the target population.

Clean and Healthy Living Behavior (CHLB) practices in a congregate setting like Pondok Pesantren plays a vital role in maintaining the health of each individual living in. This study aims to provide an overview of student’s (Santri) CHLB practices at the Pondok Pesantren Assalafiyah 2 Mlangi. It is a quantitative study using a descriptive analysis approach conducted in July-September 2022. A non-probability sampling with a total sampling of 848 santri were used. The data were collected using self-administered questionnaires developed on Google Form and imported to Microsoft Excel for further data analysis. Several indicators were assessed, including personal health maintenance, CHLB implementation, and environmental cleanliness. The results showed that the students consume fruit less than 2 timers per day (89.3%), vegetables less than 3 times per day (45.6%), drinking 6-9 glasses of water (18.3%), only 4.2% have routine exercise schedule with the duration more than 120 minutes per week, and only 44.7% students have regular sleep patterns of 6-8 hours per day. The CHLB practices implementation and environmental cleanliness used the indicators of good hand washing practices, regular bathroom and dormitories cleaning, and the overall cleanliness of the Pondok Pesantren achieved good performance which scored around 55.1-64.4%. While 45.8-50% of the students reported an average good scoring for the available cleaning and healthcare facilities. The results of this study will be used to develop recommendations related to the importance of basic personal health education using CLHB practices to promote and prevent disease transmission in congregate facilities. To improve the overall health outcomes of the students, there are some measures that could be taken, including providing training for health cadres, provision of proper healthcare facilities, and developing digital health interventions such as telemedicine applications for further consultation with healthcare professionals.

Published: September 2023

This study examined challenges of livelihood sustainability from artisanal inland water fishing activities in Ibi LGA, Taraba State, Nigeria. Descriptive survey design was adopted. Purposive sampling was used in selecting 406 respondents from 12 communities in 6 political wards of the LGA. Descriptive statistics was used to analyse 401 questionnaires retrieved. Findings of the study reveal decline in daily fish catch from three baskets 10 years ago to only one basket presently. Also, income from fishing has declined from ₦150,000 ($192) monthly 10 years ago to less than ₦50,000 ($64) presently. Factors responsible for decline in fish catch include rising water level, temperature increase, pollution, climate change, seasonality and unsustainable fishing practices. The unsustainable fishing practices include use of chemicals, small size nets and mosquito nets in fishing. The results reveal that fishermen engaged in non-fishing activities, fish farming and construction of fishing ponds along the floodplain as a way of achieving livelihood sustainability. Challenges of livelihood sustainability include seasonality of fishing activities, decline in fish stocks, use of traditional fishing methods and unsustainable fishing practices among others. The study recommend the need to enforce extant laws on fishery protection, enlightenment campaign, and government support to fishing cooperatives.

Authors: Mizar Khalid , Mulyati Sri , Arahman Nasrul 
Published: September 2023

Abstract: Dyes have toxic properties and complex chemical structures which become a threat to the ecosystem if it exposes to the environment. A photocatalyst is a semiconductor material that can run a photocatalytic process under UV or visible light to degrade most organic molecules, ideally to H2O and CO2. Tungsten trioxide (WO3) is a visible photocatalyst which could use sunlight irradiation to treat the wastewater pollutant. In this study, WO3 material was hybridized with hydroxyapatite (HAp) through the sol-gel method to degrade methylene blue (MB) synthetic pollutants. The FTIR and SEM-EDX characterization confirmed the presence element of the WO3/HAp hybrid material. The original WO3 and modified WO3/HAp photocatalysts with concentrations of 10, 15, and 20 mg were tested to degrade 15 ppm of 50 ml MB solution under visible light for 4 hours. The highest pollutant degradation was obtained using a 20 mg photocatalyst, which reached the photodegradation efficiency of 73.072% for WO3 and 88.689% for WO3/HAp. The result proved that WO3/HAp hybrid photocatalyst showed higher degradation performance than the unmodified WO3 photocatalyst. The results of this research can be developed for industrial wastewater treatment, including the papermaking, printing and dyeing industries.Abstrak: Zat warna memiliki sifat beracun dan memiliki struktur kimia kompleks yang dapat menjadi ancaman bagi ekosistem apabila terpapar ke lingkungan. Fotokatalis heterogen menggunakan semikonduktor yang memicu proses fotokatalitik dengan bantuan sinar UV atau sinar tampak dalam mendegradasi kebanyakan limbah organik, menjadi H2O dan CO2. Tungsten trioksida (WO3) merupakan fotokatalis yang dapat menggunakan cahaya matahari untuk mendegradasi polutan pada air limbah. Pada penelitian ini, WO3 dihibridisasi dengan hidroksiapatit (HAp) melalui metode sol-gel untuk mendegradasi polutan sintetik Methylene Blue (MB). Hasil karakterisasi FTIR dan SEM-EDX mengkonfirmasi unsur-unsur penyusun material WO3/HAp. Fotokatalis WO3 munri dan WO3/HAp yang dimodifikasi diuji untuk mendegradasi 15 ppm larutan MB 50 ml di bawah cahaya tampak selama 4 jam dengan konsentrasi 10, 15 dan 20 mg. Degradasi polutan tertinggi diperoleh dengan menggunakan fotokatalis 20 mg yang mencapai efisiensi 73,072% untuk WO3 dan 88,689% untuk WO3/HAp. Hasil tersebut membuktikan bahwa fotokatalis hybrid WO3/HAp menunjukkan kinerja degradasi yang lebih baik daripada fotokatalis WO3 tanpa modifikasi.
Exploring Accounting Research Topic Evolution: An Unsupervised Machine Learning Approach
Authors: Cao June , Gu Zhanzhong , Hasan Iftekhar 
Published: September 2023

ABSTRACT
This study explores the evolution of accounting research by utilizing an unsupervised machine learning approach. We aim to identify the latent topics of accounting from the 1980s up to 2018, the dynamics and emerging topics of accounting research, and the economic reasons behind those changes. First, based on 23,220 articles from 46 accounting journals, we identify 55 topics using the latent Dirichlet allocation model. To illustrate the connection between topics, we use HistCite to generate a citation map along a timeline. The citation clusters demonstrate the “tribalism” phenomenon in accounting research. We then implement the dynamic topic model to reveal the dynamics of topics to show changes in accounting research. The emerging research trends are identified from the topic analytics. We further explore the economic reasons and in-depth insights into the topic evolution, indicating the economic development embeddedness nature of accounting research.

Optimal Dynamic Relative Performance Evaluation
Authors: Hemmer Thomas 
Published: September 2023

ABSTRACT
The theoretical prediction of a negative coefficient on positively correlated peer performance underlies much of the empirical literature on relative performance evaluation. This prediction is commonly obtained from a single period model where the variance–covariance matrix of available performance measures is exogenously restricted to be independent of the evaluee’s action. Using the dynamic approach of Holmström and Milgrom (1987), I study the properties of contracts that optimally condition an agent’s compensation both on his own performance and on how well he fares relative to a peer (group) when these restrictions are not imposed. I show that if the covariance is nonzero, the optimal contract is linear in own and peer performance as well as in their correlation. Significantly, and in line with the preponderance of the empirical evidence, in its simplest and perhaps most reasonable form, the model predicts that the expected coefficient on peer performance is exactly zero.
The Impact of M&A Delistings on the Information Environment of Industry Peer Firms
Authors: Brown Anna Bergman , Byard Donal , Darrough Masako , Suh Jangwon 
Published: September 2023

ABSTRACT
This study documents that M&A delistings are associated with a deterioration in the quality of analysts’ information environment for industry peer firms, measured by an increase in analysts’ absolute forecast errors and dispersion. This effect persists for six quarters and is larger when the delisting target firm contributes relatively more to the industry information environment. Further, we find that, among analysts forecasting earnings for an industry peer firm, those who also followed the delisted target firm in the pre-M&A period experience a larger increase in their absolute forecast errors. A comparison based on public versus private target firms also suggests that the loss of target firms’ public disclosures plays a role in the deterioration in the quality of analysts’ information environment. In additional analyses, we find evidence consistent with this effect resulting from a deterioration in analysts’ ability to exploit across-firm information complementarities.

Pædagogik som videnskabsfag. Replik til Jens Erik Kristensens fremstilling
Authors: Christensen Gerd , Øland Trine 
Published: September 2023

This article seeks to elaborate on some of the understandings of ‘pædagogik’ (pedagogy) that we have observed in Jens Erik Kristensen’s article ‘Pedagogy and/or educational research and educational science’ in Nordic Studies in Education (Kristensen, 2022). In this article, we present several claims in order to argue for and be able to characterize pedagogy as a science: that pedagogy as an object of study involves an institutional perspective, that pedagogy is practiced and thus calls for empirically based and theoretically informed studies of pedagogical practice, and not least that the studies of pedagogy, according to pedagogy as a science, are critical in the sense that they seek to examine the significance of pedagogical practice, question its epistemology and make it possible to think differently.

Authors: юскаев юрий 
Published: September 2023

В данной работе проведено исследование работ в которых отображены мировые данные по эффективности ПБ с 1960-2023гг.
При этом данные в предлагаемом исследовании были отсортированы по следующим критериям : общая эффективность т.е насколько эффективны ПБ без указания были ли применены РБ или нет то есть это максимально общая не детальная оценка применения ПБ в реальных ДТП экспериментальных расчетах. Следующая таблица отображает данные эффективности ПБ без применения РБ, затем показаны публикации и результаты эффективности ПБ совместно с РБ . И заключительная таблица эффективность работы ПБ по шкале AIS-MAIS. Проведенные исследования показали: что вопреки ожиданию авторов нет линейной корреляции по эффективности ПБ с временем проведения исследования хотя в конструкции ПБ вносились многочисленные изменения направленные на искоренение недостатков и поиск различных улучшений. Результат данного исследования заключается в первую очередь в изменчивости человеческого организма и множестве переменных влияющих на результат ДТП при условии применения ПБ. В данном исследовании приведены только те данные которые прямо относятся к автомобильной травме. Необходимо провести анализ полученных данных с помощью математического аппарата.
De la modernidad al futuro, estructuras y profesionales, 130 años del Hospital Provincial y Clínico de Valladolid (1889-2019)

Published: September 2023

Los hospitales de una población, son punto de referencia relevante en su historia. Su funcionamiento suele ser extenso a lo largo del tiempo y en algún caso su existencia puede ser equiparable a la de la propia ciudad, como sucedió con el antiguo Hospital de Esgueva en Valladolid. En todas las poblaciones suele haber hospitales emblemáticos sobre las que durante largos periodos han sido punto de referencia de la atención sanitaria de la población. El hospital Clínico Universitario de Valladolid, si nos atenemos a sus datos de prestaciones y actividad, es el hospital más importante de la ciudad y que tuvo su antecesor en el Hospital Provincial y Clínico, clausurado para la actividad sanitaria, cuando se inauguró el primero. Entre ambos suman un periodo de actividad de 130 años en el momento actual a los que por continuidad habría que añadir el denominado Hospital de la Resurrección abierto en 1544 para desempeñar sus funciones, que a la vez fue cerrado y demolido cuando se abrió el Provincial y Clínico en 1889, lo que suma un total de casi 500 años de soporte hospitalario de la ciudad del Pisuerga; aunque curiosamente los tres hospitales al que habría que añadir un cuarto, el Hospital de Esgueva, están vinculados por proximidad de sólo varios metros al cauce del otro rio de Valladolid, que es el Río Esgueva.
