Authors: Wulandari Arviana
Published: April 2021

Over the changing times, human activity has grown, now the propaganda that is valued between men and women results in more women having an outside flurry to get continued. Enables them to buy something fast, including when it comes to serving food. One that was raised by the food industry plays is by presenting frozen food (Frozen Food). The purpose of this research is to study how the marketing strategies carried out by the "Family Mantab" in increasing business and increasing BRAND AWARENESS in the community in East Jakarta. The research method used in this research is descriptive method by collecting data through interviews, observations and distribution of online questionnaires for frozen mantab kebab buyers in East Jakarta. This is evidenced in the t test the marketing strategy has a significant level of 0,000 and a calculated t value of 5,650> t table of 0.05. This means rejected so that it can be announced that the marketing strategy is significant to BRAND AWARENESS, this is evidenced that t table> t arithmetic (5,650> 0.05) and t arithmetic values> t table (8.239> 0.05). Pearson relation coefficient of product moment marketing strategy of .446** it means  that the correlation or positive realtionship between variable marketing strategy and brand awareness is 0,466 or in the coefficient interval between 0,40-0,599 means the level of relationship between the variable marketing strategy and brand awareness is being. Thus it can be concluded that the alternative hypothesis (Hα) which reads "Is a Marketing Strategy on BRAND AWARENESS".

Published: April 2021

A newly discovered saurischian dominated tracksite in the Lower Cretaceous Jiaguan Formation in southeastern Sichuan province reveals 13 sauropod trackway segments representing ichnogenus Brontopodus and three theropod trackways. This is a typical Type 1 Jiaguan Formation deposit dominated by tetrapod tracks with no significant tetrapod body fossils. The tracks occur in a river channel exposure of feldspathic quartz sandstone about 20–25 m wide and ~ 60 m long. The trackways are exposed on both banks but eroded away in the central channel area. The sauropod tracks represent relatively small animals with pes print lengths ranging from 24.5 cm to 33.9 cm. The theropod trackways include a large example (footprint length 46.5 cm with metatarsal traces) and two smaller parallel trackways with footprint lengths less than 20 cm. The author also discussed the erosion of tracks and trackways by water erosion, especially their morphological changes.

By means of online real-time data collection and synchronous analysis technology, the Shanghai rail transit online monitoring system for track safety status and its vibration and noise takes shape, thereby achieving real-time monitoring for on-site vibration and noise as well as safety status, and providing assistant decision-making reports in connection with relevant index systems and in accordance with relevant time periods.
Verification and Optimization of Metro Fare Clearing Models Based on Travel Route Reconstruction
Authors: Yichao Pu
Published: April 2021

How to verify and optimize metro fare clearing models efficiently and accurately is a research focus in metro operations. Metro fare clearing models are mostly based on probability distributions. In such models, the normal distribution of travel time corresponding to the section probabilities is used to calculate the route choice probabilities of passengers on a multi-route metro network. By integrating the operating mileage proportions of each metro line operator and the corresponding route choice probabilities, the fare clearing proportions are calculated for all the operators of the metro network. To verify the accuracy of the fare clearing proportions, we propose a travel route reconstruction approach based on cell phone data acquisition technique. With wireless access point (AP) sensors installed at transfer stations, the unique medium access control (MAC) address of the smart phone with Wi-Fi function turned on is recorded and transmitted to a data analysis platform. After matching the MAC address information with time and location, the travel route of the smart phone user is reconstructed. Then, the parameters in the fare clearing model are verified and optimized according to the travel route choice probabilities. The proposed methodology is applied in Hangzhou metro network for experiment, and the metro fare clearing model is verified and modified by reconstructing the actual travel routs of the local passengers.

O Plano Diretor como instrumento de planejamento e gestão urbana dos centros emergentes no Norte de Minas/MG
Authors: Melo Bernardes Brenda , Esdras Leite Marcos
Published: April 2021

O Plano Diretor desempenha um importante papel no planejamento e gestão municipal, contudo, apesar da sua relevância e obrigatoriedade para cidades com mais de 20.000 habitantes, na prática presencia-se, em muitos municípios, a dificuldade da sua implementação e de articulação das diretrizes propostas com o desenvolvimento local. No Norte de Minas, objeto de estudo desse artigo, essa situação é agravada pela carência de investimentos públicos na mesorregião e pela necessidade de fortalecimento das relações intermunicipais para obtenção de recursos orçamentários de entes federais e estatais. Desse modo, pretende-se por meio deste artigo compreender a influência que os princípios de ordenamento do solo e as políticas de educação e saúde, explicitadas nos planos diretores, exercem no desenvolvimento dos centros emergentes no Norte de Minas. Sobre os métodos de pesquisa adota-se a abordagem qualitativa com a utilização de pesquisa bibliográfica e documental.
A presença de disciplinas voltadas ao projeto de espaços livres de lazer urbano nos cursos de Arquitetura e Urbanismo da Região Sul do Brasil
Authors: Paulus Covaleski Joani , Vieira Romano Fabiane , Rossi Lopes Limberger Lucienne , De Conto Vanessa
Published: April 2021

Este artigo reflete sobre o ensino de projeto de espaços livres de lazer e recreação urbanos. Com discussões sobre a criação e o entendimento de espaços livres desde as décadas de 1930 e 1940, e com a institucionalização, a partir de 1994, da disciplina de paisagismo e projeto da paisagem nos cursos de Arquitetura e Urbanismo brasileiros, os espaços livres urbanos ganham a importância equivalente a que, até então, era somente atribuída ao espaço edificado. Assim, abre-se espaço para análise da constituição das disciplinas de projeto na grade curricular de cursos de Arquitetura e Urbanismo na Região Sul do Brasil, para entender a presença de projetos de espaços livres de lazer urbano.
(Re)escrevendo a história da cidade: o mercado de terras de Passo Fundo (1920 – 1950)
Authors: Carretta Diniz Pedro Henrique , Christie Oliveira de Almeida Caliane
Published: April 2021

Este artigo se insere na temática da história urbana, tomando Passo Fundo, localizada no noroeste do estado do Rio Grande do Sul, como objeto de estudo. O objetivo foi analisar o processo de formação e transformação da mencionada cidade, com atenção especial ao período conformado entre as décadas de 1920 e 1950, quando diversos loteamentos privados e vilas operárias foram concebidos e transformaram significativamente as dinâmicas e o traçado urbano. Este estudo foi baseado em dados primários, coletados dos arquivos públicos da cidade, e foi dividido em três etapas: pesquisa bibliográfica, pesquisa documental e pesquisa iconográfica. Percebe-se, para além das obras de modernização e qualificação empreendidas no espaço urbano, que o mercado de terras de Passo Fundo ainda é um campo de estudos pouco explorado pela historiografia especializada. Apesar de muitos dos loteamentos e vilas terem dado origem a importantes bairros, especialmente nos anos compreendidos no recorte temporal apresentado, tal tema ainda não foi objeto de interesse de pesquisa local. Espera-se que este artigo contribua para o preenchimento dessas lacunas, trazendo novos dados e contribuindo para um maior conhecimento da história urbana de Passo Fundo.

Published: April 2021

The Western Balkans are an important hotspot of caddisfly diversity in Europe, with several microscale endemics, many of which were discovered during the recent years. The genus Potamophylax Wallengren, 1891 likely originated and diversified in Europe, with the Balkan Peninsula being one of the most important diversity hotspots.

In this paper, we describe the new species Potamophylax coronavirus sp. n. from Bjeshkët e Nemuna National Park in the Republic of Kosovo. The new species belongs to the Potamophylax winneguthi species group and is morphologically most similar to Potamophylax juliani Kumanski, 1999, currently known only from Bulgaria and Potamophylax winneguthi Klapalek, 1902, known from Bosnia and Herzegovina and Serbia. The male of the new species differs from its most similar congeners mainly in exhibiting: (1) elongated subrectangular superior appendages in lateral view; (2) hardly acuminate, almost rounded apex of intermediate appendages; (3) differently shaped, irregular and higher inferior appendages; (4) narrow spinate area, roughly rectangular in dorsal view, slightly wider at the base and (5) different paramere shape and/or spine pattern. The new species also differs by its considerably smaller size and association with open, high altitude eucrenal zones.

The uncorrected interspecific pairwise distance between P. coronavirus and other species of the P. winneguthi species group is on par with those amongst other recognised species in the group, as well as with the yet ambiguously identified taxa from the Sharr, Rila and Bajgorë Mountains.

The new species is most probably a microendemic of Bjeshkët e Nemuna, thus highlighting further this area as an important hotspot of caddisfly biodiversity in Europe.

La retraite par répartition au crible de la pensée multi-solidaire
Authors: Masson  André
Published: April 2021

Les débats suscités par le projet de réforme du système de retraite français, pourtant assez bien accueilli au départ, ont surtout révélé l’ampleur des désaccords concernant aussi bien les défauts du système actuel et les objectifs de la réforme que la pertinence du système universel proposé. L’étude cherche déjà à mieux comprendre ce dissensus patent en remontant à la source des désaccords. Celle-ci est d’ordre idéologique , opposant les visions a priori du monde social avancées par trois pensées du social : celles du libre agent, de l’égalité citoyenne et multi-solidaire. Tout discours sur le social correspond, grosso modo , à un point à l’intérieur de ce triangle idéologique. Les clivages entre les trois pensées, qui se nouent autour du rôle attribué à la famille et de la vision des liens et transferts entre générations, conduisent à des architectures des transferts sociaux (volume global, priorités selon l’âge, etc.) et à des systèmes de retraite très différenciés. Le système français actuel s’inspire d’abord de la pensée multi-solidaire, le projet de réforme, dans sa version initiale, de celle de l’égalité citoyenne. Les systèmes de retraite existants semblent de plus en plus rechercher un compromis entre les pensées du libre agent et de l’égalité citoyenne, assimilant la retraite en répartition à un dispositif financier soumis à des choix individuels. Les vocations d’assurance sociale et de solidarité intergénérationnelle de la retraite s’estompent. La suite de l’étude montre comment des propositions de réforme innovantes, inspirées par la pensée multi-solidaire, permettraient de retrouver ces vocations pour mainte forme actuelle de la répartition.
Épargne retraite
Authors: Hamayon Stéphane , Pradat Yannick , Legros Florence
Published: April 2021

La loi PACTE du 22 mai 2019 vise à orienter l’épargne vers des placements longs productifs en favorisant l’essor de l’épargne retraite. Elle aspire conjointement à modifier la ligne de partage entre répartition et capitalisation. Cette disposition pose deux questions. Celle de l’impact de la capitalisation sur la croissance et celle de la dynamique que l’on prête aux actifs risqués. Cet article est centré sur la mesure du risque associée à l’utilisation des revenus du capital pour financer les retraites et examine la question centrale de l’utilité que les agents peuvent retirer de leur abondement au fonds d’épargne. Les résultats des simulations réalisées dans le cadre démo-économique français montrent que si le prix des actifs risqués suit une marche aléatoire (EMH), les agents averses au risque ne pourront pas obtenir sur les marchés un ratio « rendement/risque » équivalent à celui procuré implicitement par l’édifice des régimes par répartition. En revanche si les chocs sur les marchés boursiers ont un caractère transitoire, alors le marché financier pourrait concurrencer les régimes par répartition au prix d’un investissement massif en actifs risqués en début et milieu de vie active.
Système universel de retraite et taux de taxation marginal implicite des cotisations retraite
Authors: Gannon Frédéric , Le Garrec Gilles , Touzé Vincent
Published: April 2021

Cet article étudie comment l’adoption d’un système universel (SUR) par points impacte le taux de taxation marginal implicite de la cotisation retraite. À partir des formules de calcul des droits à pension, nous identifions deux facteurs centraux pour analyser la nature du changement : le facteur de revalorisation du salaire et le taux de remplacement marginal du salaire revalorisé. Nous observons également que le mode de calcul de la pension à prestations définies versée par la CNAV induit une discontinuité car seules les hausses marginales de salaires associées aux meilleures années cotisées comptent. Nos calculs montrent dans quelle mesure la cotisation SUR élimine cette discontinuité et réduit également le taux marginal de taxation de la cotisation AGIRC-ARRCO grâce à une meilleure indexation de la valeur des points. La cotisation SUR n’élimine pas le taux marginal implicite mais conduit à un profil plus lisse sur l’ensemble du cycle de vie.
Le lent développement des évaluations d’impact en France : une approche par les acteurs
Authors: Bono Pierre-Henri , Desplatz Rozenn , Debu Sandra , Lacouette-Fougère Clément
Published: April 2021

En s’appuyant sur les résultats de deux études récentes commandées par France Stratégie, l’article propose une analyse critique du développement institutionnel et académique de l’évaluation d’impact des politiques publiques en France. Il montre que les évaluations d’impact, reposant sur des méthodes statistiques contrefactuelles, représentent une part faible – bien que croissante – des évaluations réalisées dans notre pays et qu’elle n’est produite que par quelques centres de recherche spécialisés. Les acteurs institutionnels de l’évaluation des politiques publiques (ministères, Parlement, Cour des comptes…), qui promeuvent une conception de l’évaluation plus large que l’identification de liens de cause à effet entre une politique et les résultats observés, ne font quasiment jamais appel à ce type de méthodes scientifiques. Le rôle joué par l’Insee et des services statistiques des ministères (SSM), à mi-chemin entre l’administration et la recherche, constitue une spécificité française dans le développement des pratiques d’évaluation d’impact.
Le rôle des institutions supérieures de contrôle dans les transformations des pratiques évaluatives : l’exemple de la Belgique

Published: April 2021

À partir du cas de la Cour des comptes de Belgique, la présente contribution examine la dynamique d’enrichissement et de diversification des pratiques évaluatives à l’œuvre au sein des institutions supérieures de contrôle. Ces évolutions posent de nouveaux défis institutionnels et organisationnels pour les entités en charge du contrôle de la dépense publique comme l’attention croissante portée à l’impact des activités d’évaluation, l’effritement des cadres traditionnels de l’action publique et la coexistence de rationalités professionnelles multiples.
Quelle(s) pratique(s) d’évaluation dans les collectivités locales ?

Published: April 2021

Trois constats ressortent d’une récente enquête en ligne à la fois quantitative (89 collectivités de plus de 40000 habitants) et qualitative (11 monographies) réalisée pour le compte du CNFPT : la trajectoire des pratiques évaluatives est incertaine ; les objectifs des évaluations sont plus techniques que politiques, avec des élus trouvant difficilement leur place et des usagers faisant irruption dans le processus ; l’utilité est multiforme, les stratégies très pragmatiques mises en œuvre visant en définitive plus l’accompagnement que le jugement. Trente ans après son introduction progressive, sommes-nous à l’orée d’une nouvelle étape pour l’évaluation dans les collectivités territoriales ?
Une privatisation de l’état bleu ? Ingénierie publique, ingénierie privée dans la gouvernance territoriale des risques littoraux
Authors: Mazeaud Alice , Rieu Guillaume
Published: April 2021

Depuis le début des années 2010, l’affirmation des pouvoirs publics (État et collectivités territoriales) dans le domaine de la gestion des risques littoraux est manifeste. Cependant, l’inégale distribution de l’expertise et les relations entre ingénierie publique et ingénierie privée nous semblent avoir été trop peu analysées. Si, dans le cas de la Charente-Maritime étudié ici, le département est parvenu à gagner une compétence dans la gestion des risques littoraux grâce à son ingénierie, l’essentiel des savoirs, savoir-faire et moyens matériels nécessaires à la mise en œuvre de ces politiques est détenu par les bureaux d’études privés, ce qui nous conduit à formuler la thèse d’une privatisation de l’« État bleu ».
Speculative behavior and chaotic asset price dynamics: On the emergence of a bandcount accretion bifurcation structure
Authors: Panchuk Anastasiia , Westerhoff Frank
Published: April 2021

We study a simple financial market model with interacting chartists and fundamentalists that may give rise to multiband chaotic attractors. In particular, asset prices fluctuate erratically around their fundamental values, displaying a significant bull and bear market behavior. An in-depth analytical and numerical study of our model furthermore reveals the emergence of a new bifurcation structure, a phenomenon that we call a bandcount accretion bifurcation structure. The latter consists of regions associated with chaotic dynamics only, the boundaries of which are not defined by homoclinic bifurcations, but mainly by contact bifurcations of particular type where two distinct critical points of certain ranks coincide.

Authors: Doganer Adem , Zuopeng (Justin) Zhang
Published: April 2021

A new type of coronavirus (COVID-19), detected at the end of December 2019 in Wuhan, China, can pass from person to person, spreading very quickly. The COVID-19 outbreak has created stress among societies. This study aims to evaluate the usability of Google Trends data in predicting and modeling the COVID-19 outbreak and the attitudes of different societies to it by using an infodemiological method. The authors collected the search words related to coronavirus and their relative search volume (RSV) from 11 different countries affected by the COVID-19 outbreak from Google Trends. A positive correlation was found between the trend rate of the words searched on the internet and the number of COVID-19 cases in countries related to the COVID-19 outbreak (p<0.05). There was a significant difference between 11 country societies in the daily RSV for the COVID-19 outbreak (p<0.05). The Turkish, South Korean, Iranian, and Swiss society have searched more intensely on the internet for COVID-19 than others. The research shows that Google Trends data can be used to build the forecast model for case numbers in the COVID-19 outbreak. Besides, Google Trends data provides information about different societies' attitudes in the COVID-19 outbreak.

Authors: An Lu , Hu Junyang , Xu Manting , Li Gang , Yu Chuanming
Published: April 2021

The highly influential users on social media platforms may lead the public opinion about public events and have positive or negative effects on the later evolution of events. Identifying highly influential users on social media is of great significance for the management of public opinion in the context of public events. In this study, the highly influential users of social media are divided into three types (i.e., topic initiator, opinion leader, and opinion reverser). A method of profiling highly influential users is proposed based on topic consistency and emotional support. The event of “Jiankui He Editing the Infants' Genes” was investigated. The three types of users were identified, and their opinion differences and dynamic evolution were revealed. The comprehensive profiles of highly influential users were constructed. The findings can help emergency management departments master the focus of attention and emotional attitudes of the key users and provide the method and data support for opinion management and decision-making of public events.

Published: April 2021

Basal cell carcinoma (BCC) is characterized by slow but locally invasive growth. Although there is low metastatic potential, if not treated early, these skin cancers can lead to significant morbidity and mortality. In this case report, we present a man with a neglected BCC that developed into what is termed a giant BCC or one that is greater than 5 cm. This tumor was discovered only upon workup of orthostatic lightheadedness and iron deficiency anemia. Although rare, basal cell carcinoma must be included on the differential of a large cutaneous lesion and may be a source of significant blood loss.

Authors: Tetikkurt Cuneyt , Kubat Bahar , Kulahci Cigdem , Tetikkurt Seza , Caliskaner Ozturk Buket
Published: April 2021

Idiopathic pleuropulmonary fibroelastosis is an extremely rare lung disease characterized by the combination of fibrosis of the visceral pleura and the fibroelastotic changes transcending in the subpleural lung parenchyma that predominantly affects the upper lobes with accompanying volume loss. It is mostly idiopathic while infection, autoimmunity, bone marrow or lung transplantation and genetic predisposition may be associated with the development of PPFE. The disease is exceptionally rare as approximately ninety cases have been reported in the literature currently. A 35-year-old female presented with exertional dyspnea, dry cough and weight loss. Physical examination demonstrated platythorax, suprasternal notch deepening and fine rales over the upper lobes. Blood count, serum biochemistry, autoimmunity and serologic markers for collagen vascular diseases were within normal limits. Arterial blood gases demonstrated a low pO2 (48 mm Hg) and a high pCO2 (54 mm Hg) values. Chest x-ray showed bilateral parenchymal fibrotic lesions, left pneumothorax, bronchiectasis in the middle and pleural thickening in the upper lung zones while HRCT revealed bilateral apical pleural thickening, traction bronchiectasis, subpleural reticulations, ground-glass opacities and honeycombing in the upper lobes. Bronchoscopy, BAL cytology, smear and culture did not reveal any pathologic findings. Relevant with the clinical, laboratory, radiologic manifestations and the differential diagnosis with other interstitial lung diseases, PPFE was the final diagnosis. The aim of this case report was to present the clinical manifestations of our case. The second crucial objective was to establish a diagnostic scoring system relevant with the literature and the clinical manifestations of the patient.
Detection of human papillomavirus high-risk genotypes in rural women of Lucknow, North India
Authors: Srivastava Anand Narian , Misra Jata Shanker , Rizvi Saliha
Published: April 2021

Background:

Human papilloma virus (HPV) has been widely implicated in cervical carcinogenesis and 90% of carcinoma cervix cases are due to high-risk HPV infection. This study was done to find the high-risk HPV genotypes in the rural women of Lucknow, North India.

Materials and Methods:

HPV-DNA testing has been carried out in 130 cases of squamous intraepithelial lesions (SILs) of the cervix to find HPV status and type of high-risk HPV genotype infecting the rural women. These cases were collected from the rural cervical cancer screening program carried out in the villages of West Lucknow, North India.

Results:

HPV status in 130 SIL cases revealed HPV positivity in only 17 cases (13.1%), whereas the remaining 113 cases were HPV negative (86.9%). HPV genotypes detected in the study were HPV-18, HPV-31, HPV-33, and HPV-35. HPV positivity was found highly associated with the young and sexually active group of women complaining of vaginal discharge. High HPV infection rate was also seen with multiparity and illiteracy as majority of women attending the camps were multiparous and illiterate.

Conclusions:

The present study revealed highly oncogenic HPV-18 alone or in combination with multiple infections of high-risk genotypes – 31, 33, and 35 – in the rural women of Lucknow, North India. Since HPV vaccine currently available in India is for HPV-16 and HPV-18 combined, efforts should be made to make region-specific vaccine according to their prevalence in that particular state of the country to provide effective HPV vaccination.
Improving Memory Exploitation in M-health Applications through Context-Aware System
Authors: Belhadi Siham , Merzougui Rachid
Published: April 2021

INTRODUCTION: The mobile application requires some information about its environment in order to the adaptation of its behaviour according to this information in a transparent manner. However, such a task usually needs the resource consumption of mobile devices.OBJECTIVES: the main goal of this work was the design of the context aware infrastructure for the healthcare applications embedded on mobile devices. This last aims to the integration of the context awareness into the execution environment and providing a adequate methodology of the generic context manager, with the maintenance of low level the resource consumption.METHODS: This collected the context information (medical data) thanks to the component (Context Element Monitor). When the components set acquire values of different elements context which belong the same class, these components run in the same time. it is mean the execution of its in a group way. From the state of monitors (ACTIVE or DISABLED), our system creates the new context situation. The mobile application is structurally an assembly of services. The adaptation methodology revolves around the execution manager of services according to the new created context situation. This approach ensures the best use of resources depending on the characterization of context and reduces the amount of contextual information in the adaptation processes.RESULTS: We evaluated a memory space in three cases, since it is the most resource that is affected in the field of the mobile health (mobile patient monitoring application). For this, we estimated the consumed memory at two levels: the first is the management module "Context Manager" and the second level considers the adaptation procedure. In the Context Manager, the first and the third case were the exploited memory space was almost identical, Knowing that its consumption is varied between 1556 and 2026 KB. But in the second case, it increased and become varying between 2424 and 6848 KB. the other hand, in the adaptation mechanism, it is necessary a huge space of a memory for managing services more than 40000 kb.CONCLUSION: Our own approach of context manager and adaptation can open the new way in the m-health applications development. This allows these applications that can exploit the great quantity and the different type of a medical data with the best use of the memory space.

Background: In spite of concerted global efforts to reduce childhood mortality, countries in Sub-Saharan Africa are still being plagued with incomparably high mortality rates; thereby contributing majorly to the global burden. These deaths occur from causes which are preventable. Men play a pivotal role in sustained efforts to reduce childhood mortality, however, they are usually overlooked in favour of the mothers. The study aimed to assess the knowledge and attitude of men towards factors influencing childhood mortality in a semi-urban community, North-Western Nigeria.Methods: A descriptive cross-sectional study was conducted using structured interviewer-administered questionnaire. A total of 174 married men were sampled using a multistage sampling technique. Data collected were analysed using the IBM SPSS version 21. Results were presented in tables and bar charts. The level of statistical significance was set at p<0.05.Results: The mean age (±SD) of the respondents was 38 (±11.2) years. One hundred and ten (64.7%) of the respondents had lost a child under the age of five years. Majority 142 (83.5%) of the respondents had poor knowledge of risk factors influencing childhood mortality and 141 (82.9%) of the respondents had a positive attitude towards prevention of childhood mortality.Conclusion: The study has highlighted the need for increased male involvement in child health issues. Interventions such as health education and community mobilization that aims to educate men on risk factors and danger signs associated with poor childhood health outcomes should be carried out in this area.

Background: COVID-19 is a global pandemic affecting over 25 million people with more than one million deaths and having different patterns of clinical presentation. The study aimed to describe the patterns of clinical presentation of COVID-19 patients in Federal Medical Centre, Asaba, Nigeria.

Methods: After obtaining an ethical approval, a facility-based retrospective cross-sectional study was carried out among 50 eligible patients in the hospital’s isolation ward. Data was collected from the patients’ case notes using a proforma to describe the epidemiological history, medical history, symptoms, signs, treatment measures and complications. Data were analyzed with Statistical Package for Social Science (SPSS) version 20 and presented as percentages, mean and standard deviation.

Results: The mean age of respondents was 44.7 ± 17.3 years with slightly higher proportion of female 26 (52.0%) and majority 41 (82.0%) had tertiary level of education. Fever 29 (76.3%), followed by malaise 19 (50.0%), cough 18 (47.4%), difficulty with breathing 14 (36.8%) and headache 14 (36.8%) were the most common presenting symptoms while majority 43 (86.0%) of the respondents had mild to moderate clinical presentation. The commonest source of the infection was close contact with confirmed case 33 (66.0%).

Conclusion: Mild to moderate cases of COVID-19 were more, with over two-third of the patients being symptomatic. The replication of this study in other COVID-19 treatment centers/isolation wards will aid in the better management of COVID-19 patients.

Background: School health program takes care of the health needs of a significant proportion of the population, especially in the third world countries, by ensuring that children of school age remain healthy and benefit maximally from their education. This study aimed to assess the knowledge of School Health Programme (SHP) among primary school teachers in Sokoto metropolis, northwestern, Nigeria.Methods: A cross-sectional study was conducted among 382 public primary school teachers that were selected by multistage sampling technique. Data was collected using a structured, self-administered questionnaire. Proportions and adjusted odds ratios (OR) were calculated with 95% confidence intervals (CI) in a binary logistic regression model. All levels of significance were set at p < 0.05.Results: The mean age of the respondents was 34.8 ± 8.6 years. More than half of the respondents were Nigerian Certificate in Education (NCE) holders 245 (64.1%). Knowledge of SHP was good in 198 (51.8%) of the respondents. The predictors of good knowledge were belonging to other ethnicity (aOR: 3.70; 95% CI=1.11–12.50, p=0.034), having degree or postgraduate qualification in education (aOR: 4.55; 95% CI=2.63–7.69, p<0.001) and having worked for two or more decades (aOR: 4.15; 95% CI=1.34–12.78, p=0.011)Conclusion: Nearly half of the respondents had poor knowledge of SHP and this is likely to deny a large number of school children of being healthy and benefitting from th eir education. Awareness campaigns and trainings on SHP to fill in the knowledge gap is highly recommended.

Published: April 2021

Background: Adolescents with hearing loss are often faced with poor cognitive and executive functions, and increased prevalence of mental health problems. The study compared the perceptual reasoning skills (PRI) and mental health problems of deaf adolescents with those of their age- and sex- matched hearing counterparts.Methods: It was a comparative cross-sectional study of a total population (102) of deaf adolescents, who were matched for age and sex with 102 normal hearing adolescents. The PRI of the participants was assessed using the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV). Mental health problems were assessed with the parents’ and teachers’ versions of the Strengths and Difficulties Questionnaire (SDQ). Descriptive statistics, chi square test and correlation co-efficient were done. Significant level was set at p-value < 5%.Results: The PRI scores ranged from 41-106 across both groups; 58.8 % of the deaf and 41.2% of the hearing adolescents scored 69 and below on the WISC and this difference was statistically significant (p = 0.033). The PRI scores had no significant relationship with the audiometric scores of the deaf participants (r = -0.177; p = 0.076). The PRI scores in the deaf participants were inversely related to hyperactivity assessed by the teacher (r = -0.354), emotional difficulty assessed by both teachers (r = -0.221) and parents (r = -0.280) and peer problems assessed by the teachers (r = -0.329).Conclusion: Deaf participants in this study showed significantly lower level of nonverbal IQ and higher level of behavioural difficulties compared with their hearing counterparts.
