Published: November 2022

The presence of coliforms, Mastadenovirus (AdV), and Canine protoparvovirus (CPV) in an Environmental Education Center, which contains city kennel, was investigated. Surface water and wastewater, dogs’ stool, and lettuce samples were collected from the irrigation system in both periods October 2017 and February 2018. Water samples were analyzed for the presence of human AdV (HAdV) and canine AdV (CAV), CPV, total coliforms (TC), and Escherichia coli; lettuce for AdV; and dog stool for CAV and CPV. Sixty-seven samples were analyzed: dog stool (n = 33); water (n = 10), and root, stem, and leaf (n = 24) originated from eight lettuce samples. Coliforms and E. coli were tested by Colilert and viruses by PCR assays, respectively; and the amplicon was sequenced. E. coli, TC, and viruses were detected in both collections. Viruses were detected in 34.3% of samples, of which HAdV-C was present in 13% of water samples; HAdV-E in 8.7% (water and lettuce); CAV-1 in 13% (dog stool and water); CPV-2a in 56.5% (dog stool). Raccoon CPV-like and AdV not characterized were detected in one wastewater samples and one dog stool, respectively. To our knowledge, this is the first description of the presence of Raccoon CPV-like in water and HAdV-E in lettuce in Southern Brazil.

Published: November 2022

Water policies play a critical role in good water governance and sustainable water development. The evaluation of water policies helps improve the quality of water policy systems and water governance. This study quantitatively evaluated water resource management policies through the policy modeling consistency (PMC) index model and a text-mining method based on national water resource management policy texts produced from 2011 to 2019. This study constructed an evaluation index system based on the water resource management policy's high-frequency words, including 9 first-level variables and 43 second-level variables; furthermore, it compared and analyzed key water resource policies based on the PMC index and PMC surface. The results showed that China's water resource management policies are generally applicable, but it needs to be improved. China's water resource management policies are reasonable in terms of policy nature, policy function, policy priority, and function level, and need to be further improved in terms of policy prescriptions, incentive constraints, policy fields, policy evaluations, and policy priorities. This study thus provided a scientific basis for the optimization of water resource management policies and water governance capacities in China.
Research on the comprehensive evaluation of the value of water conservancy heritage based on expert knowledge and public cognition: a case study of Red Flag Canal
Authors: Wang Yanrong , Fu Hao , Zhang Shujing , Jiapaer Nilupa
Published: November 2022

The scientific construction of the indicator system and the objective evaluation method that apply to the value of water conservancy heritage are of great significance to the promotion and development of water culture and water conservancy heritage conservation. This study constructs an index system for water conservancy heritage value assessment from seven first-level indexes, such as engineering value, economic value, social value, ecological value, artistic value, innovative value and heritage value, builds a fuzzy comprehensive evaluation model based on expert knowledge and public perception and carries out empirical evidence with the example of China's Red Flag Canal. The results show that the overall value of the Red Flag Canal was 94.68 points, which reached a high level. The result is consistent with that the Red Flag Canal was successfully declared as the national water conservancy heritage, thus verifying the scientificity and rationality of the index system and the evaluation method constructed by this study.
Preparation, Characterization and in vitro/vivo Evaluation of Long-Acting
Rivaroxaban-Loaded Microspheres
Authors: Tan Chunli , Xiong Subin
Published: November 2022

Background:

Rivaroxaban is widely used for long-term prevention and maintenance therapy
of thromboembolic disorders. The existing oral dosage forms of rivaroxaban lead to poor patient adherence
because of repeated daily administration. The aim of this study is to design long-acting rivaroxaban-
loaded microspheres to reduce dosing frequency and improve patient compliance.

Methods:

Rivaroxaban-loaded microspheres were prepared using the emulsion-solvent evaporation
method. The microspheres were evaluated in terms of morphology, particle size, drug loading and encapsulation
efficiency, the physical state of the drug in the matrix, in vitro release/release mechanism,
and in vivo pharmacokinetics in Sprague Dawley rats.

Results & Discussion:

Rivaroxaban-loaded microspheres presented spherical-shaped particles displaying
a mean particle size of 89.3 μm, drug loading of 16.5% and encapsulation efficiency of 97.8%. The
X-ray diffraction indicated that rivaroxaban existed in crystal form in the microspheres. In vitro release
lasting approximately 50 days was characterized as a tri-phasic pattern: (1) an initial burst release,
mainly due to the dissolution of drug particles with direct access to the microparticles’ surface, (2) a
“plateau” phase with a slow-release rate controlled by the diffusion and (3) a final, rapid drug release
phase controlled by polymer erosion. Pharmacokinetic studies showed that rivaroxaban microspheres
maintained a sustained release for more than 42 days.

Conclusion:

Rivaroxaban-loaded microspheres have great potential clinical advantages in reducing
dosing frequency and improving patient compliance. The data obtained from this study could be used as
scientific evidence for decision-making in future formulation development.

Authors: Wannous Boshra Ibrahim , Khaddam Jamal , Ismaiel Mohamad Adel
Published: November 2022

Background:

Chronic Urticaria is one of the most therapeutic difficulties confronted by a dermatologist.

Objective:

The objective of this study is to estimate the efficacy of Autologous Serum Therapy (AST) in Chronic Urticaria patients and compare the efficacy of AST in each group of Autologous Serum Skin Test (ASST) positive and negative.

Methods:

A prospective study was conducted for the period of one year (July 2020 – July 2021) at Tishreen University Hospital. We enrolled 50 patients suffering from Chronic Urticaria. ASST was done for all patients before the treatment. We gave patients 9 injections of Autologous Serum intramuscularly once a week. The response to AST was evaluated by using Urticaria Total Severity Score (UTSS) before the treatment (0 weeks), after the treatment (9 weeks), and followed up for 3 months after the end of the treatment (21 weeks).

Results:

Between 50 patients, the sample was distributed equally in each group of ASST (positive and negative). 18 patients (36%) had an excellent response, 7 patients (14%) had a very good response, 11 patients (22%) had a good response, and 14 patients (28%) had no response. The treatment was effective in both ASST positive and negative groups, however, there was no significant relationship in response between the two groups.

There was a significant relationship between clinical response and severity of disease p-value = 0.04, the majority of excellent response cases (88.9%) had severe disease before the treatment.

Limitations:

The main limitations of our study were the lack of patients and the short follow-up period (12 weeks).

Conclusion:

AST was effective in treating Chronic Urticaria without side effects. There was a significant response in both ASST positive and negative groups.
Construções ditransitivas e estrutura informacional em Português Europeu quando o OD é um constituinte pesado
Authors: Brito Ana Maria
Published: November 2022

The text analyses the relation between argument structure and information structure with “core dative verbs” in European Portuguese (EP), specifically in the constructions with heavy direct objects (DO). Developing some previous analysis , I will argue in favour of the proposal that EP has a basic construction of ditransitives where the DO is projected as complement of a low verbal category and the IO is projected in the specifier position of that verbal category. When the DP DO raises to a higher position because of Case reasons, the order V DO IO is obtained. With a heavy and focalized DO the order is V IO OD and that can be explained if the DP DO leaves a spelled-out copy. This approach makes discursive functional categories such that topic and focus in the left periphery of the Verbal Phrase unnecessary and reinforces the view that in languages like European Portuguese information structure relates, in a very strong way, Syntax and Phonology and Syntax and Prosody.
Núcleos funcionais e variação linguística o caso da Reestruturação
Authors: Gonçalves Anabela
Published: November 2022

The idea that linguistic variation results from the properties of functional heads goes back to the 1980s (e.g. Borer 1984) and is particularly important within the generative model known as Minimalist Program. This paper intends to present more empirical evidence favouring this approach, considering the contrast between European Portuguese (EP) and Brazilian Portuguese (BP) as far as Restructuring is concerned (available in EP only). It is claimed that this contrast is not due neither to different temporal relations between the embedded and the matrix domains nor to the functional heads projecting in the former. Instead, the difference between the two varieties results from different properties of the embedded functional heads below T, namely Asp and vP: in EP, but not in BP, these heads may be defective for φ-features, which triggers the phenomena related to Restructuring, such as clitic climbing and long object movement to the matrix domain.
On Evidentiality and Perception Ambivalent adjectives in the Spanish non-finite complements of ver
Authors: Carrasco Gutiérrez Ángeles
Published: November 2022

In this paper, I will pay attention to the behavior of adjectives such as altísimo and torpe, called ambivalent (Luján 1981) or underspecified (Fernández Leborans 1995), due to the fact that they can be combined with both the copulative verb ser and the copulative verb estar in languages such as Spanish. More specifically, I am interested in two structures, both of them dependent on the Spanish verb of perception ver. In the first, altísimo and torpe combine with the copula estar in infinitive clauses. In the second, subordinate infinitive clauses are headed by the copula ser. I will try to elucidate which is the contribution of the copulative verbs to the interpretation of these structures. With Escandell-Vidal (2018), I assume that the adjectives altísimo and torpe in combination with estar give rise to an evidential effect: the spatio-temporal situation to which the property they denote is anchored is conceived as a situation of visual experience. In the first of the structures I am interested in, the source of information is likewise encoded in the verb of perception. Therefore, the research question that will guide this study is whether the evidential content is actually being expressed twice.
Contraste, concessão e contra-argumentação em textos académicos uma análise exploratória
Authors: Duarte Isabel Margarida , Pinto Alexandra Guedes , Rodrigues Sónia Valente
Published: November 2022

The present study takes an integrated approach of grammatical elements and structures from the perspective of their functioning in texts/discourses. It focusses the semantic-pragmatic and argumentative-discursive values of utterances represented by the conceptual scheme Yes... But..., in academic writing, in particular master’s theses and reports. Its object are discursive sequences with a composite argumentative movement comprising concession and contrast /counter-argumentation. From a wide universe of works, made up of final reports from FLUP Master’s students, from the years 2020-2022, five works were selected in which the discursive sequences in focus frequently occur. The set of clipped sequences constituted the corpus of this study. After the theoretical framework, an exploratory analysis of qualitative and interpretative nature was carried out, based on procedures such as: the segmentation of utterances with movements of concession and contrast, starting from the identification of linguistic elements related to the conceptual scheme Yes..., But...; the categorization and description of these segments, taking into account syntactic-semantic and pragmatic-discursive dimensions; the comparison of the values displayed by the sequences of the different categories; the explanation of the occurrences in the academic genre in question; the articulation of the linguistic elements with the enunciative, interactional and contextual dimensions of discourse production. The results show that contrastive constructions, such as adversative and concessive, acquire, in discourse, very similar semantic-pragmatic and discursive-argumentative functions, serving to mark mitigated discordant polyphony and a confrontational strategy that combines agreement (even if partial) with disagreement, a strategy that proves to be particularly appropriate in the discursive genre under analysis. They also demonstrate that this movement is present in academic works with higher classifications, in the final assessment of the course, working as evidence of the author’s capacity for problematization and critical, divergent thinking. In this way, it may come to function as a specific marker to improve the academic writing competence.
A vista da ponte das pessoas que vão em fila a caminho do céu um relance sobre a composicionalidade das palavras complexas do chinês e do português
Authors: Veloso João
Published: November 2022

Semantic compositionality, as the principle that makes it possible to compute the global meaning of a complex unit from the specific meanings of its constituents, is usually accepted (at least when Indo-European languages are considered) as exclusive of sentences. Even in the case of complex words, the role of compositionality is accepted very limitedly only. In languages like Chinese, though, where most simple words are monosyllabic – thus, generating a high rate of homophones –, forming complex words on the basis of the compositional combination of simple words is a highly productive, systematic linguistic resource of the language. In this paper, we shall argue for the need of always assessing linguistic principles, such as compositionality, in relation to particular languages; in tandem with this tenet, we shall favour the view of Chinese complex words as compositional structures (differently from what occurs in Indo-European languages, namely). This conclusion is in line with previous studies on this subject.

Me-Leader versus We-Leader: Bhagavad Gita Perspectives on Transformational Leadership
Authors: Kuknor Sunaina , Rastogi Shailesh , Singh Satyendra Pratap
Published: November 2022

The Bhagavad Gita is one of the world's oldest known holy scriptures, dating back over 5,000 years. The scripture, which Hindus believe was inspired by God, contains unique perspectives and prescriptions for today's leaders. The Gita advises managers to seek a higher level of consciousness. It makes them influence people and lead compassionately and inclusively. The Bhagavad Gita advocates a consciousness approach to transformational leadership based on eternal values and moral principles. Many researchers and practitioners in business leaders identify the Bhagavad Gita as one of the most famous and quoted works in Indian literature. The paper attempts to assist business leaders with insights into Indian scriptures and how they can benefit from the ancient writings of spiritual gurus. Therefore, the authors pursue extracting and elaborating the Bhagavad Gita's concepts into business leadership. Specifically, the study indicates how lessons from Gita can help transform a transactional leader, 'me-leader',into a transformational 'we-leader'.
Consumer Misbehaviour in Services: A Qualitative Study in India
Authors: Bhattacharjee Anindo , Purohit Neha
Published: November 2022

Consumer misbehaviour is a growing phenomenon these days in the services sector. The perils of the job of being a call centre executive or the incidences of verbal abuse or aggression on employees in services or deviant consumer behaviour such as shoplifting by customers in retail outlets is widely known but rarely reported. In fact many organizations, in their pursuit of following the mantra of “customer is king” become victims of wrong behaviour by the customers itself. The current study not only identifies the antecedents or motives of consumer misbehaviour that could be of interest for marketers but also proposes strategies to deal with or neutralize the consumer misbehaviour. The area of consumer misbehaviour in an emerging market context is still an under-researched area and every organization faces it in some form or the other. The findings of this paper are based on a nation-wide qualitative study on consumer misbehaviour based on semi-structured interviews. We are reporting the findings based on 24 of such interviews. We proposed a conceptual framework that can be the starting point for future confirmatory studies in this area of consumer research.
Food Waste at Household and Social Gatherings: Drivers and Possible Remedies
Authors: Srivastava Saurabh Kumar , Singh Sandeep , Srivastava Medha
Published: November 2022

Over the course of the food supply chain, approximately one-quarter of the food produced for human consumption is thrown away. According to the World Food Waste Survey, food waste created at the household level accounts for almost half of the total food waste. Agrowing number of people are becoming concerned about food security and environmental consequences, such as resource depletion and greenhouse gas emissions associated with food waste. This has heightened public awareness of the issue. Despite the fact that food waste happens at every level of the food supply chain, private households have been recognized as being the primary source of food waste production. However, there is currently a lack of studies about the factors that influence consumer food waste behavior. This paper presents a twofold study. In the first section, this paper maps drivers of food waste at household level along with the remedies backed by extensive literature review. In the second section, this study identifies factors which are responsible for food waste in social gathering with special reference to weddings along with solutions to prevent food waste in the context to social gathering through systematically reviewing empirical studies on food waste practices. The results of the study demonstrate that food waste is a complex and multi-faceted issue that cannot be reduced to a single variable; as a result, a more comprehensive integration of multiple academic viewpoints is required. The mapping of the factors of waste creation allows for a more in-depth knowledge of household habits, party organizers’practices, guest behaviors toward food, and the development of food waste control policies. Finally, we connect the factors that have been found with formulation of policy, business, and social responsibilities. This study will be a value addition in the existing pool of literature concerned with responsible consumption and sustainable practices.
Influence of Social Interaction on Customer Experience in Tourism Industry
Authors: Agarwal Nidhi , Mohan Ashutosh
Published: November 2022

Customer experience has always been a pivot around which every industry revolves. Customer experience refers to sum total of beliefs, perception, feelings & emotions a person develops over a period of time. It is the entire customer journey in which the Customer experience is built up. Social Interaction is one of the contributing factors of customer experience. Social interaction occurs when two or more people communicate with each other intentionally or unintentionally. The level of interaction decides the customer experience. Tourists are the people who travel and visit a place (location) other than their usual surroundings for leisure purposes. The more friendly & helpful interaction a tourist encounters at the destination, the better his/her experience and vice-versa. Various factors influence the customer experience in the customer journey, but the paper focussed on only one factor i.e. social interaction. The paper consists of three objectives in which the first two objectives check the influence of social interaction based on gender and age-group of tourists during the onsite phase of customer journey, and the last objective is to find out the influence of Social interaction on customer experience during the onsite phase of customer journey. The questionnaire was prepared for conducting a survey, Kruskal-Wallis test and Spearman’s Rank correlation analysis was performed to check the proposed hypothesis.
Analysis of Accreditation of Indian Universities Located in the Western Part of India Considering NAAC Quality Indicators
Authors: Inda Shyam Singh . , Srinivasulu Kocherla .
Published: November 2022

With the introduction of the National Education Policy 2020, the focus of higher education in India is shifting towards the holistic development of students through multidisciplinary education. It also envisages higher education institutions with motivated, skilled, and focused faculty members who are capable of providing quality teaching-learning process as well as engaged in visible and relevant research. Also, universities are mainly meant to cater to large masses, conduct research that is of societal importance, and reach out to society through extension activities. Looking into these aspects, the quality assessment of the universities is of utmost importance for their complete development. The overall progress of universities will depend upon the formulation and implementation of policies leading to a better teaching-learning environment, infrastructure for teaching and research, mobilization of funds, excellence in research, and extension activities. Uniformity in the evaluation of the quality of the universities requires taking all these factors into consideration. National Assessment and Accreditation Council, which evaluates the quality of higher education institutions in India, grades the universities based broadly on these criteria. In this paper, we attempt to analyze the accreditation of universities based on their grades obtained in various criteria set by NAAC. We have also tried to find the correlation of some of the criteria on other quality indicators.

Objective. Hg was quantified in the dorsal muscle of the 11 species of fish most consumed in San Marcos, located in the region of La Mojana. Materials and methods. Dorsal muscle samples were taken from the fish species, T-Hg concentrations were quantified using cold vapor atomic absorption spectrophotometry (CVAAS). Results. The species with the highest Hg-T values ​​were those with carnivorous eating habits: Pseudoplatystoma magdaleniatum (0.44 ± 0.09 µg/g), Plagioscion surinamensis (0.42 ± 0.14 µg/g) and Hoplias malabaricus (0.39 ± 0.11 µg/g). However, the maximum recommended amount of Hg in fish (0.5 µg/g) set by the European Union, was not exceeded by any of the species studied. Conclusions. It is concluded that the commercial ichthyofauna of La Mojana is contaminated by Hg, a result of the mining activities that take place in the channels of the rivers that discharge in this region. The persistent consumption of fish from the evaluated areas by its inhabitants represents a high risk, due to the high toxicity of Hg, which presents adverse effects on human health even when it is consumed in low doses for prolonged periods of time.

Objective: The aim of this work was to determine the rates of prevalence and recurrence of TVT infection in owned dogs, as well as the distribution of the disease, in Cuajinicuilapa, Guerrero, Mexico. Methods: This work was an observational, descriptive, longitudinal study. A TVT diagnosis was performed in all dogs in the community based on clinical records, a physical examination, and a cytological evaluation, and further confirmed by histopathology. Tissue samples were surgically obtained for histopathological analysis and, when required, to remove tumors and give treatment with vincristine; a GPS system was used to identify possible spatial groupings. All cases were re-evaluated one year after. Results: A prevalence of 5.15% was found in 1047 dogs (512 females and 535 males; 25 positive females and 29 positive males). TVT infection was more frequent in 2–3-years-old dogs. A spatial aggregation pattern was observed in the local cases. One year after, no lesions were found in the 29 animals treated. Conclusion: TVT is a common disease, and its distribution suggests its aggregation in certain areas of the locality. Further studies on the dynamics of dog populations in small cities are required.

Published: November 2022

BACKGROUND

The HIV epidemic continues to disproportionately burden marginalized populations despite the availability of effective preventive and therapeutic interventions. Trans women are severely affected by HIV worldwide including in Brazil and other low- and middle-income countries (LMICs), with evidence of increasing new infections among young people. There is an urgent need for youth-specific HIV prevention and care interventions for young trans women in Brazil.

OBJECTIVE

The Brilhar e Transcender (or BeT) study is a status-neutral HIV intervention with the following aims: (1) to address stigma in the Brazilian public health system, (2) to reduce barriers to HIV care and prevention with systems navigation among young trans women aged 18-24 years in Rio de Janeiro, Brazil.

METHODS

BeT is a peer-led single arm digital intervention study enrolling 150 young trans women in Rio de Janeiro, Brazil. The intervention was pilot tested and refined using data from a formative phase. The BeT intervention takes place over three months, is delivered remotely via mobile phone and in-person by peers is comprised of three components: 1) BeT sessions, 2) digital interactions, and 3) automatic messages. Eligibility includes those aged 18-24 years old, trans woman, Portuguese speaking, and lives in Rio de Janeiro metropolitan area in Brazil. The primary outcomes are HIV incidence, PrEP uptake, linkage to HIV care and viral suppression. Primary outcomes were assessed at baseline and quarterly for 12 months. Participants respond to interviewer-based surveys and receive HIV and sexually transmitted infections testing.

RESULTS

The study has been approved by the Brazilian and the US local institutional review boards in accordance with all applicable regulations. Study recruitment began in February 2022 and were completed on early July 2022. Plans are underway to complete the follow-up of study participants and to analyze study data and disseminate intervention results upon study completion.

CONCLUSIONS

Interventions to engage a new generation of trans women in HIV prevention and care are needed to curb the epidemic. The BeT study will evaluate a digital peer-led intervention for young trans women in Brazil that builds upon ways young people engage in systems and utilizes peer-led support to empower trans youth in self-care and health promotion. A promising evaluation of the BeT intervention may lead to availability of this rapidly scalable status-neutral HIV intervention that can be translated throughout Brazil and other LMICs for young trans women at high risk or living with HIV.

The Effect of Monetary Incentives on Health Care Social Media Content: Study Based on Topic Modeling and Sentiment Analysis (Preprint)
Authors: Maleki Negar , Padmanabhan Balaji , Dutta Kaushik
Published: November 2022

BACKGROUND

While there is high-quality online health information, a lot of recent work has unfortunately highlighted significant issues with the health content on social media platforms (eg, fake news and misinformation), the consequences of which are severe in health care. One solution is to investigate methods that encourage users to post high-quality content.

OBJECTIVE

Incentives have been shown to work in many domains, but until recently, there was no method to provide financial incentives easily on social media for users to generate high-quality content. This study investigates the following question: What effect does the provision of incentives have on the creation of social media health care content?

METHODS

We analyzed 8328 health-related posts from an incentive-based platform (Steemit) and 1682 health-related posts from a traditional platform (Reddit). Using topic modeling and sentiment analysis–based methods in machine learning, we analyzed these posts across the following 3 dimensions: (1) emotion and language style using the IBM Watson Tone Analyzer service, (2) topic similarity and difference from contrastive topic modeling, and (3) the extent to which posts resemble clickbait. We also conducted a survey using 276 Amazon Mechanical Turk (MTurk) users and asked them to score the quality of Steemit and Reddit posts.

RESULTS

Using the Watson Tone Analyzer in a sample of 2000 posts from Steemit and Reddit, we found that more than double the number of Steemit posts had a confident language style compared with Reddit posts (77 vs 30). Moreover, 50% more Steemit posts had analytical content and 33% less Steemit posts had a tentative language style compared with Reddit posts (619 vs 430 and 416 vs 627, respectively). Furthermore, more than double the number of Steemit posts were considered joyful compared with Reddit posts (435 vs 200), whereas negative posts (eg, sadness, fear, and anger) were 33% less on Steemit than on Reddit (384 vs 569). Contrastive topic discovery showed that only 20% (2/10) of topics were common, and Steemit had more unique topics than Reddit (5 vs 3). Qualitatively, Steemit topics were more informational, while Reddit topics involved discussions, which may explain some of the quantitative differences. Manual labeling marked more Steemit headlines as clickbait than Reddit headlines (66 vs 26), and machine learning model labeling consistently identified a higher percentage of Steemit headlines as clickbait than Reddit headlines. In the survey, MTurk users said that at least 57% of Steemit posts had better quality than Reddit posts, and they were at least 52% more likely to like and comment on Steemit posts than Reddit posts.

CONCLUSIONS

It is becoming increasingly important to ensure high-quality health content on social media; therefore, incentive-based social media could be important in the design of next-generation social platforms for health information.

Epidemiology and Perception of Acne Among Adolescents in Jos, Nigeria: Cross-Sectional School-Based Study (Preprint)
Authors: Adah Ruth , Yusufu Hope , Otene Queen-Amina Vivian
Published: November 2022

BACKGROUND

Adolescents who make up a vast majority of the secondary school population are at a stage at which they are largely affected by acne. This condition, which is widely visible and easily recognized by peers, has numerous misperceptions surrounding it, which may influence attitudes toward people affected by it. There is a paucity of information on the prevalence of acne and how adolescents in Jos, Nigeria, view the condition.

OBJECTIVE

This study aimed to determine the prevalence of acne, perceived risk factors, and the accuracy of self-report among adolescents in Jos, Nigeria. The study also sought to understand perceptions surrounding acne in this age group.

METHODS

This descriptive cross-sectional study was conducted among adolescents attending private and public secondary schools in Jos, Nigeria. In total, 482 students were recruited through a multistaged stratified random sampling method. A self-administered semistructured questionnaire was used to collect information on history of acne, perceptions of causes, and the attitude toward those who have the condition. All participants were examined for the presence of acne. Univariate, bivariate, and multivariate analysis were conducted using SPSS (version 26; IBM Corp).

RESULTS

The self-reported prevalence of acne was 44% and that upon clinical examination was 55%. Self-report showed a moderate degree of agreement with clinical diagnosis (Cohen κ=57.3%; P<.001). Predictive factors for the presence of acne in general were age of ≥15 years (odds ratio [OR] 1.79, 95% CI 1.12-2.87; P=.02), being in a private school (OR 2.17, 95% CI 1.38-3.42; P=.001), and being in a senior secondary class (OR 2.14, 95% CI 1.32-3.47; P=.002). The female gender (OR 3.03, 95% CI 1.64-5.61; P=.001) and religion (OR 3.24, 95% CI 1.27-8.24; P=.02) were predictive for acne only among adolescents aged <15 years, while a positive family history was predictive in those aged ≥15 years (OR 2.04, 95% CI 1.15-3.61; P=.02). A distinct perception and attitude pattern surrounding acne was observed, as a significant proportion (84/131, 64.1% vs 47/131, 35.9%; P=.02) of those who related acne to a biological phenomenon had acne themselves; however, the belief that acne is caused by skin lightening practices was significantly more common in those without acne (19/28, 67.9%) than in those with acne (9/28, 32.1%; P=.01). One-fourth of the adolescents (n=122, 25.3%) had no idea of the possible causes of acne.

CONCLUSIONS

Though acne is a prevalent skin condition among Nigerian adolescents, many misperceptions and unfavorable attitudes surround acne and persons affected by the condition. Our findings have revealed the need to work with the school health program to educate the general adolescent population about acne, to refer and manage teenagers with acne.

Summary: Object detection is a computer technology related to computer vision and image processing concerned with detecting instances of semantic objects of a certain class in digital images and videos. Machine learning can be used to detect and classify objects in images and videos. Vehicle detection, also known as computer object recognition, is essentially scientific methods and means of seeing machines, not human eyes. Vehicle detection is one of the features most used by businesses and organizations today. We can use computer vision to detect different types of media on video or in real time through the camera. Vehicle detection and tracking is used in traffic control, car tracking, parking sensor creation, and more.
Customer Churn Prediction in Banking Sector - A Hybrid Approach
Authors: Mandava Sreenitya , Gupta Anvita , Srikar Komanduri
Published: November 2022

Abstract: No institution wants to lose customers and would do anything to prevent it. But banks can’t do anything about customer churn unless they predict it first. Predicting customer churn will help them to reach out to such customers and offer the assistance they need. With the support of precise and early churn prediction, customer resource management, and customer experience teams can be more assertive and customer-focused. It has been reported that simply reaching out to customers early enough can prevent 11 percent of attrition. The problem remains about how to predict such behaviour. Surveys are difficult to undertake and not many are interested in answering them. Past data holds the required solution. We can predict the behaviour of present and future customers by using machine learning and data science techniques to learn from this past customer data. In this paper, we aim to conduct a comparative analysis of different churn prediction models for banking institutions. Then we would implement a hybrid approach with the considered advantages from each of the best performing models for a given cluster of the dataset, to get better results.

Abstract: Our Proposed system is to develop a Web Application for hiding information in any image file to ensure the safety of the exchange of data between different military parties and provide better security during message transmission. The scope of the project is the implementation of steganography tools for hiding information including any type of information file and image file and the path where the user wants to save the image and extruded file. We use the LSB technique. The proposed approach is to use a steganography algorithm for embedding data in the image files for military applications. For security purposes we used modules face Recognition technique with AES algorithm for Strong Security purpose. And we use the cover channel technique as an information hiding technique that can be exploited by a process to transfer information in a manner that violates the system security policies. And we use copyright marking techniques. In short, Cover Channels transfer information using nonstandard methods against the system design.d. Deep learning techniques used for image steganography can be broadly divided into three categories - traditional methods, Convolutional Neural Network-based and General Adversarial Network-based methods.

Authors: B L Nanda
Published: November 2022

Abstract: As the presence of excess free radicals in body can cause damage to the system and may lead to several diseases like Alzheimer’s, Parkinson’s, Cancer, Atherosclerosis and many more. Free radicals should be neutralized or eliminated out of the body. Apart from the antioxidants present in biological system natural antioxidants available from the diet help in the removal of free radicals from the body. Therefore, the antioxidants present in fruits, vegetables and medicinal herbs can be used to scavenge free radicals and treat the disorders due to oxidative stress. Five different medicinal herbs were collected locally to quantitate phytochemicals, antioxidant activity and inhibition of lipid, protein and sugar oxidation. Among the different samples, highest Phenolics, flavonoid and antioxidant activity was seen in aqueous extract of Ocimum basilicum. This study demonstrates that it can be used in nutraceuticals and can be a potential source of natural antioxidants to combat the free radical mediated diseases.

Published: November 2022

Abstract: This project proposes a way to control the position of the cursor with the bare hands without using any electronic device. While the operations like clicking and dragging of objects will be performed with the different hand gestures. The proposed system will only require a webcam as an input device. The software that will be required to implement the proposed system are OpenCV and Python and the libraries used for this model is MediaPipe. The output of the camera will be displayed on the system’s screen so that it can be further calibrated by the user. The python dependencies that will be used for implementing this system are NumPy, math and mouse. It’s a new approach for controlling mouse movement using a real time camera. Major approaches consist of adding more buttons or charging the position of the tracking ball of mouse. Instead we suggest to change the design of hardware. Our concept is to use a camera and computer vision technology, as a image segmentation and gesture recognition, to control mouse tasks and we show how it can perform everything that current mouse devices do.
