CORRELATION OF craniovertebral PARAMETERS WITH THE RETROPHARYNGEAL SPACE IN POSTERIOR C1-C2 ARTHRODESIS
Authors: Silva Luis Eduardo Carelli Teixeira da , Barros Alderico Girão Campos de , Fagundes Fábio Antônio Cabral de Araújo , Atencio Gamaliel Gonzalez
Published: April 2022

ABSTRACT Introduction/Objective: The craniovertebral junction (CVJ) requires a detailed evaluation, as the changes in alignment caused by surgery can affect adjacent structures in a secondary way. Examples of these effects are dyspnea or dysphagia after posterior occipitocervical arthrodesis, due to decreased caliber of the oropharynx. These changes can be identified perioperatively by several radiographic parameters that aim to predict possible postoperative respiratory complications. Such complications appear to be related to the narrowest oropharyngeal airway space (nPAS), and may also occur following atlantoaxial (C1-C2) arthrodesis. This work aims to correlate the variation in CVJ alignment parameters before and after C1-C2 arthrodesis with the variation in nPAS. Methods: Patients who underwent posterior C1-C2 arthrodesis between 2011 and 2019 at the National Institute of Traumatology and Orthopedics (INTO) were included in the study, totaling 26 patients. The parameters evaluated included cervical lordosis, C1-C2 angle, slope of C2, Occipito-C2 angle (O-C2), pharyngeal inlet angle (PIA), pharyngeal tilt angle (PTA), occiput and external acoustic meatus to axis angle (O-EAa), cranial transverse motion against C2 angle (C2TA), axial tilt (AT) and the percentage of change in nPAS (%∆nPAS). Results: A correlation was observed between the change in C1-C2 angle, O-C2, PTA, C2TA and the %∆nPAS. Conclusion: The change in cervical alignment and CVJ parameters is correlated with %∆nPAS and should, therefore, be evaluated before and after atlantoaxial fusion as a means of predicting a possible respiratory complication.

Published: April 2022

ABSTRACT Objective: To verify the influence of sedentary behavior and physical activity on the prevalence and situation of low back pain in medical students at a higher education institution. Methods: Cross-sectional study with a quantitative approach, conducted with 220 students. Data were collected between January and February 2021, using the Roland-Morris Disability Questionnaire. Data were analyzed using the Statistical Package for the Social Sciences Program. Values of p ≤ 0.05 were accepted as statistically significant. Results: Sixty-five percent of the participants were female, the average student age was 24.19 years, and a predominance of students were in the clinical cycle (60.9%). Of the total sample, 75.9% (n=167) stated that they performed physical activities and 28.2% (n=62) responded that they spend between 7-10 hours sitting studying. The prevalence of low back pain was high (84.1%; n=185), however, only 1.5% (n=3) had scores indicative of functional disability. Women (Mean=5.07, SD=0.35) had greater functional disability than men (Mean=3.33, SD=0.35; p=0.008). Sedentary students had greater disability (Mean=5.79, SD=4.55) than active students (Mean=4.04, SD=3.62; p=0.007); individuals who spent more than 7 hours a day sitting also had higher scores (p=0.02). Conclusion: The findings indicated a significant self-reported prevalence of low back pain among medical students, with greater functional disability in females, sedentary individuals, and those who sat for more than 7 hours a day.

Characterization and optical properties of polymer nanocomposite films for optoelectronic applications
Authors: Alotaibi Badriah M , Al-Yousef Haifa A , Alsaif Norah A M , Atta Ali
Published: April 2022

Polymer nanocomposite films combining polyaniline (PANI) and lead (II) sulfide (PbS) nanoparticles (PbSNPs) were effectively synthesized using a casting solution approach for use in optical energy applications. Transmission electron microscopy, X-ray diffraction and infrared spectroscopy showed that PbSNPs were successfully introduced into the PANI matrix. Scanning electron microscopy images revealed that lead (II) sulfide was homogenously loaded and distributed in the PANI chain. Using ultraviolet–visible optical absorbance, the optical parameters of PANI/PbSNPs were evaluated, including absorption edge (E d), bandgap (E g), carbon cluster number (N) and Urbach energies (E u). PbSNPs were investigated for their impact on PANI polymer linear optical as well as non-linear optical characteristics, including refractive index, non-linear susceptibility and dielectric parameter. When comparing the PANI/PbSNP film to the pure PANI film, the bandgap of the PANI/PbSNP samples was found to be reduced significantly. However, the addition of PbSNPs increased the predicted value of optical conductivity and the carbon cluster number. The addition of PbSNPs to the PANI polymer improved its optical characteristics, resulting in a synthetic composite that can be used in energy applications as well as optoelectronic devices.
Masterly Confusion: Ported Protection in the American Interwar
Authors: Fowler Justin
Published: April 2022

In domestic design projects ranging from carpet prototypes for the Metropolitan Museum in New York to bridge infrastructures for Robert Moses, architects Ralph Walker and Aymar Embury II drew from their experiences of trauma, play, and tectonic improvisation as camoufleurs during the First World War to work through logics of protective concealment. As with the operations of artillery and personnel camouflage, where makeshift flat tops of fabric and foliage provided portable spaces of relief within a brutal theater of reciprocal violence, the 'masterly confusion' of much interwar architectural work long deemed 'modernistic', middlebrow, or not fully modern was often animated by therapeutic desires for safety and comfort. Here, designs which sought to mask or avoid the aesthetic and physiological shocks of modernity also furthered the entrenchment of modern forms of mobilization, organization, and risk management. This essay traces how formal ambivalence born out of protective necessity on the battlefields of the First World War migrated across surfaces and mutated into surfaces back in the United States, advancing fluid forms of capital and corporatism via subtle tectonic and material means across a range of scales. It also argues that descriptive difficulty with respect to interwar style (and its relation to 'modernity') starts to dissolve when switching registers to look at the attitudes that pervade these architectural practices of conscious equivocation. This work marks a critical episode in modern architecture's construction of an expanded notion of environment, where engagement was produced through and experienced as relief.
Sayı Mistisizminin Arap Dilindeki Yansıması: Vâv-ı Semâniye -Tarihsel Bir Okuma Denemesi-
Authors: Çifçi Mehmet Faruk
Published: April 2022

Bu makale; bazı Arap dilcileri, edebiyatçıları ve tefsir âlimleri tarafından Arap dilinde sâbit bir kullanım olduğu iddia edilen vâv-ı semâniyenin tarihsel arka planı ve ideolojik yansımaları hakkındadır. Konu yaklaşık on asırdır muhtelif tefsirlerde ve gramer kitaplarında lugavî bir tartışma şeklinde ele alınmış, lehte ve aleyhte taraftar bulmuştur. Özellikle Kur’ân’ın sırları çerçevesinde değerlendirilmeye müsait oluşu konunun günümüzde de gündemde kalmasının başlıca sebeplerindendir. Ancak gramatik açıdan güçlü temellere dayanmayan bir iddia olmasına rağmen bu kadar ilgi görmesi vâv-ı semâniye düşüncesinin ardında farklı bir motivasyonun olabileceği ihtimalini akla getirmiştir. Bu makale bahsi geçen motivasyonu tespit etmek için kaleme alınmıştır. Çalışmada, konuyu herhangi bir yönüyle ele alan birçok tefsir ve gramer eseri kronolojik olarak incelenmiş, ayrıca vâv-ı semâniye kuralının isnat edildiği ilk dönem dilcilerinin eserlerinde bu görüşün izi sürülmüştür. Bu çerçevede yürütülen çalışmada vâv-ı semâniye düşüncesinin lugavî yönünün yanında sayı mistisizmiyle de alakalı olduğu tespit edilmiştir. Diğer yandan Seb‘iyye olarak da anılan İsmâilîye fırkasının bir dönem benimsediği yedili devir inancını güçlendirmek üzere vâv-ı semâniye kuralını kullanmaya çalıştığına dair ciddi bilgiler elde edilmiştir. Ancak takribî 700/1300 yıllarından sonra vâv-ı semâniyenin bu yönlerinin göz ardı edildiği ve nahvî bir meseleye dönüştürüldüğü görülmüştür.

Gastrointestinal Stromal Tumors (GISTs) are rare tumors of the digestive tract. The small intestine is the second most frequent localization of GIST after the stomach. We report a case of the ileal stromal tumor. The patient was admitted with a picture of hemorrhagic shock due to massive rectal bleeding. The fiberscope performed after stabilization was not objectified at the origin of the document while the CT scan objectified a mass of tissue density at the level of the right iliac fossa. Given the increasing evolution with the recurrence of patients to a target of a laparotomy for diagnostic and therapeutic purposes objectifying the tumor of the right iliac fossa at the expense of the ileum. The surgical procedure consisted of a major segmental resection of the tumor with ileo-ileal anastomosis. The anatomopathological study confirmed the diagnosis of the stromal tumor with good evolution. Through a general review of the literature, we have described the various clinical, para-clinical, anatomopathological, prognostic, and current therapeutic aspects specific to these tumors.

Abelhas sem ferrão são insetos nativos brasileiros e que desempenham um elevado potencial polinizador para inúmeras culturas agrícolas e plantas nativas. Tetragonisca angustula é uma das espécies mais manejadas pelos meliponicultores, deste modo, conhecer estrutura genética dessas populações é de grande importância, principalmente, para futuros projetos de conservação. Para isso, neste estudo foi realizado a caracterização bioquímica e a relação genética por eletroforese das isoenzimas esterase (EST), isocitrato desidrogenase (IDH), enzima málica (ME) e malato desidrogenase (MDH). Abelhas adultas foram coletadas em meliponários de Maringá e Astorga na região Noroeste do estado do Paraná, Brasil. T. angustula de Maringá apresentou dois locos polimórficos (22,22%) e oito locos polimórficos foram observados em T. angustula de Astorga (88,89%). A heterozigosidade média estimada para T. angustula foi de 0,1260. O valor de FIS foi de 0,4036 e indicou um excesso de homozigose. O valor FIT mostrou que as duas populações não foram diferenciadas, sem nenhum fluxo gênico entre elas. Os resultados sugerem a mesma origem para as duas populações de acordo com a distância genética de Nei.

Abstract
Stingless bees are native Brazilian insects and have a high pollinating potential for countless agricultural crops and native plants. Tetragonisca angustula bees are one of the species most managed by honey farmers and knowing about the genetic structure of these populations is of great importance, especially for future conservation projects. For this, the biochemical characterization and genetic relationship by electrophoresis of esterase (EST), isocitrate dehydrogenase (IDH), malic enzyme (ME), and malate dehydrogenase (MDH) isozymes was analyzed.  Adult bees were collected from meliponaries in Maringá and Astorga in the northwestern region of the state of Paraná, Brazil. T. angustula from Maringá presented two polymorphic loci (22.22%) and eight polymorphic loci were observed in T. angustula from Astorga (88.89%).  Average heterozygosity estimated for T. angustula was 0.1260. FIS value was 0.4036 and indicated an excess of homozygous. FIT value showed that the two populations were not differentiated, without any gene flow between them. The results suggest the same origin for the two populations in agreement with Nei’s genetic distance.

Abstract
The Ti-6Al-4V alloy presents elements harmful to the organism, such as aluminum and vanadium, demonstrating the importance of developing new Ti alloys with the addition of non-toxic elements. The elements were melted and machined for the study; the samples were divided into groups without surface treatment (Group I) and with surface modification by Yb: YVO4 laser beam irradiation in two conditions: 20Hz (Group II) and 35Hz (Group III). Structural and microstructural characterization was performed by evaluating Young's module, scanning electron microscopy (SEM) with elemental microanalysis by X-ray dispersive energy (EDX), and X-ray diffractometry (XRD). The results report an alloy of predominantly β structure and the formation of a layer of titanium oxides on the surface of the alloy in the three conditions studied, indicating protection of the material from chemical reactions related to its environment exposed to (NaCl 0.9%). The characterizations showed favorable results to laser beam irradiation, noting the formation of TiO2 compounds that are important and responsible for the attraction of bone tissue cells and bone/implant interaction.

Authors: Alghamdi Hamdan
Published: April 2022

Patients with a complex periodontal/restorative esthetic condition can only be successfully treated with an interdisciplinary approach. This report presents case managed with varying levels of periodontal and prosthodontic coordination of care. A 48-year-old female patient with no medical conditions, presented chiefly to enhance her dental esthetics and eliminate the central diastema. There was also gingival asymmetry and altered passive eruption (APE). High frenal attachment was also noticed in relation the central diastema space. The depigmentation, gingivectomy, and gingivoplasy procedures were planned accordingly. After 3 months of periodontal healing, the patient returned for the final porcelain veneer restorations limiting to the upper anterior incisors. The treatment of the complex periodontal/prosthetic esthetic patient can be achieved with an interdisciplinary approach. Such a dental rehabilitation should be beginning by a comprehensive esthetic examination. Then an accurate diagnosis, prognosis evaluation, and treatment planning have to be identified. In addition, the utilization of an advanced surgical and restorative biomaterials will ensure the best result with patient satisfaction.

Published: April 2022

A pandemia da COVID-19 impactou a sociedade brasileira, desencadeando medidas de prevenção à doença, restringindo espaços considerados de alto risco e induzindo o fechamento de escolas por tempo indeterminado. Desse modo, o Ministério da Educação através da Portaria nº 544, substituiu as aulas presenciais por remotas durante a pandemia, configurando assim o ensino remoto emergencial. Institucionalizado, este ensino fomenta questionamentos e incertezas sobre seus efeitos no processo pedagógico, principalmente relacionados à Educação Física devido seu caráter particular de aprendizado. Assim, este trabalho investigou percepções e impressões de diferentes sujeitos envolvidos no processo de ensino-aprendizagem da EF escolar frente ao ensino remoto emergencial. A coleta de dados ocorreu por convite, através de questionário de caráter misto com dez questões entre abertas e fechadas, aplicadas de forma virtual. Utilizamos estatística descritiva de frequência e porcentagem e Análise de Conteúdo de Bardin (2011) para análise dos dados. Os achados mostram que há diferenças expressivas nas percepções sobre o ensino remoto emergencial e seus efeitos no processo escolar, dividindo opiniões e impressões sobre a temática. Além disso, os dados apresentam percepções mais concordantes referentes à perda nas relações entre professor/aluno no processo pedagógico, dificuldades de acesso e sobre o crescimento da inatividade física dos alunos nesse período. Por fim, apesar das dificuldades enfrentadas, os sujeitos caracterizam o ensino remoto emergencial como uma estratégia parcialmente positiva para o aprendizado do componente curricular.

Published: April 2022

Angiosarcoma is a rapidly progressing malignant skin tumor associated with a poor prognosis. We report an immunohistochemical investigation of chemokine receptors in angiosarcoma. The aim is to investigate chemokine receptor expression and, if it is expressed, to histologically discuss its association with age, sex, development site, and histological type. Analyzed were 12 angiosarcoma samples (mean patient age: 75.7 years old) collected by biopsy or surgery from patients at our department by comparing with 4 granuloma telangiectaticum samples (mean patient age: 37.5 years old) and 16 healthy skin samples as controls. CXCR4, CCR6, CCR7, and SDF-1 expressions were immunohistochemically investigated. CXCR4 expression was positive in 6 of the 12 samples. CCR6 and CCR7 were negative in all samples. SDF-1 was positive in 4 samples. Out of the 6 CXCR4-positive samples, 4 were SDF-1-positive. No significant difference associated with age, sex, development site, or histological type was noted in the expression of CXCR4, CCR6, CCR7, or SDF-1. Although CXCR4 is regarded as an index of tumor aggressiveness of malignant melanoma, it is suggested that chemokine receptors, such as CXCR4, do not serve as useful markers of angiosarcoma.

The positive predictive value (PPV) of smart mobile phone teledermatoscopy is not known. The main purpose of the present study was to investigate the sensitivity and positive predictive values (PPVs) of smart mobile phone teledermatoscopy. Over a period of 6 months, up to three clinical and dermatoscopic images were obtained of 67 skin lesions from 67 patients using a mobile phone camera and standard pocket dermatoscopy device. Out of the 67 patients, 44 were men (65.67%) and 23 were women (34.32%). The mean age of the patients was 39.56 ± 22.19 years (ranging from 18 to 92). The majority of the lesions (71.64%; n=48) were benign, while 11.94% (n=8) of the biopsies were premalignant and 16.41% (n=11) of the lesions were malignant. The sensitivity for the diagnosis of benign, premalignant, and malignant lesions were 93.8%, 100%, and 100%, respectively. PPVs for the diagnosis of benign, premalignant, and malignant lesions were 93.8%, 100%, and 100%, respectively. The sensitivity and PPVs of all lesions were 95.9% and 95.7%. The accuracy of the teledermatoscopic consultation with a mobile phone is very high. We therefore think that it can be a cost effective and useful method in the consultation at distance.

Tablice trwania życia (wymieralności) to konstrukcje teoretyczne budowane w oparciu o rozkłady wieku zmarłych dla modelu populacji zastojowej i ustabilizowanej bądź metodą prawdopodobieństw zgonów z uwzględnieniem struktury wiekowej ludności żyjącej. W niniejszej pracy zaprezentowano możliwości wykorzystania parametrów tablic wymieralności, skonstruowanych na podstawie rozkładu liczby zmarłych w klasach wieku i wartości przyrostu naturalnego, do szacowania wskaźników płodności i mierników sposobności do działania doboru naturalnego przez jeden z jej komponentów – zróżnicowaną wymieralność. Wskaźniki płodności szacowane z użyciem powyższej metody informują nas o potencjale (poziomie) reprodukcyjnym populacji, a sama metoda może być stosowana w sytuacji, kiedy z różnych powodów nie jest możliwe odtwarzanie reprodukcyjnych historii rodzin. Z kolei szacowanie siły nacisków selekcyjnych daje kompleksowy obraz umieralności w populacjach historycznych.
Назначение Михаила Козачинского Слуцким архимандритом. 1748–1749 гг.
Authors: Kochegarov Kirill A.
Published: April 2022

В статье рассматривается вопрос о назначении слуцким архимандритом известного преподавателя и писателя XVIII в. Михаила Козачинского. Показано как этот вопрос был тесно связан с деятельностью русского посольства в Варшаве и нежеланием польско-литовских магнатов поднимать вопрос о положении православных на ближайшем сейме. В то же время русское правительство не желало обострения отношений с одним из крупнейших литовских магнатов Великого княжества Литовского и патроном Слуцкой архимандрии – Иеронимом Радзивиллом. Сам Радзивилл при этом был готов оказать покровительство православию в обмен на удовлетворение российским двором его партикулярных интересов. При этом при назначении слуцкого архимандрита в 1748-1749 гг. не была учтена позиция слуцкого православного братства, что было чревато дальнейшим углублением конфликта вокруг архимандрии.
Postrzeganie przyrody rodzimej i obcej w dziennikach podróży Stanisława Staszica (1789-1795)
Authors: Kucharski Adam
Published: April 2022

Stanisław Staszic (1755-1826) był wybitnym myślicielem oświeceniowym, zwolennikiem reform społecznych i ojcem polskiej geologii. W swoim dzienniku podróży opisał m.in. jego trzy podróże odbyte w latach 1789-1795. Znajdują się tam opisy wyprawy krajoznawczej w okolice Krakowa oraz podróży zagranicznych do Austrii i Włoch. W trakcie tych podróży Staszic poświęcał wiele czasu i energii na prowadzenie w terenie obserwacji przyrody. Spostrzeżenia i przemyślenia zapisywał w swoim dzienniku podróży. Staszic był w tych latach guwernerem młodych magnatów z rodziny Zamoyskich. Jednak jego uwagę zaprzątały głównie kwestie geologiczne, ekonomiczne, przyrodnicze i społeczne, a nie edukacyjne. Spostrzeżenia poczynione i spisane w czasie tych wojaży wykorzystał później w swojej pracy naukowej i zawodowej.
On Mainstreaming Philosophy of Science in Psychology Through “Psychological Theoretics
Authors: Oppong Seth
Published: April 2022

The principal goal of psychological science is not application but theory. This is because a good theory yields accurate predictions and control, two preconditions for applications. Thus, good psychological science is one that produces good theories. Against the background of reproducibility crisis and the apparent non-existence of an integrated subfield of psychology addressing those issues, I submit psychological theoretics (or psycho-theoretics) as a potential solution. The scope of psychological theoretics is outlined and distinguished from other closely related subfields. It was argued that psychological theoretics has the potential to make a unique contribution to the advancement of good psychological science. It is also worth noting that even if the global community of psychologists might not be ready for psychological theoretics as a new subfield, the reforms proposed under its rubrics would still remain relevant today and in the future. Indeed, the question of whether it is completely new will surely be the subject of scientific debate.
Medical Education Research Priorities for Master’s Students in Sudan: A Qualitative Study
Authors: Burhan Amira
Published: April 2022

Background: Believing research prioritization can increase the research value and augment advances in the scientific base of any profession, this study aimed to identify research priorities relevant for medical education in Sudan.
Methods: The study was designed to capture a qualitative exploration of multiple stakeholders’ opinions. Data were collected from two stakeholder groups: experts and students of medical education in Sudan. Semi-structured individual interviews and focus groups from 10 experts and 41 learners were incorporated. The categories and subcategories, derived from experts’ data inductively through constant comparison, enhanced the development of a coding framework. This framework was used deductively to analyze the beliefs and opinions of the learners leading to a list that exemplifies priorities for medical education research.
Results: A set of seven principal and three minor themes were identified, the principal themes were: Curriculum Content, Design, and Delivery; Faculty Development; Assessment Methods; Research; Accreditation, Evaluation, and Quality; Professionalism; and Student Selection and Support. Four themes were identified to justify participants’ selections: Quality education and patient care; Accreditation of schools; Curricula contextualization; and Documentation of success stories.
Conclusion: This instrumental research fulfilled its aim to mount a set of medical education research priorities grounded in collected perceptions with optimal stakeholder engagement. Importantly, there were many more similarities than differences between these findings and those from other countries which suggests that some topics are relevant across the international arena and one may propose the commencements of an international medical education agenda.

Background: Escherichia coli O157:H7 infection causes hemorrhagic colitis and is diagnosed based on symptoms such as cramps, stomach pain, and watery diarrhea. Shiga-like toxins (Verotoxin) produced by Escherichia coli O157:H7 damages endothelial cells of both kidney and brain, causing renal dysfunction and neurological problems.
Methods: The present study focuses on identifying the prevalence of Verotoxin-producing Escherichia coli O157:H7 among diarrheal inpatients at Erode Government Hospital, India, and its antibiogram. Further, the Verotoxins were characterized by using SDS-PAGE analysis. A total of 123 samples were collected both from diarrheal stools, and strains from 37 samples (43.02 %) were found to have the presence of E. coli.  The organisms were identified based on their colony morphology on various media, cell morphology, and biochemical tests. The Shiga-like toxin production was identified by non-fermentation of sorbitol on SMAC agar plates. Confirmation of Shiga-like toxin was performed using agglutination assay.
 Results: In total, 12 isolates showed agglutination and these isolates were confirmed to be E. coli O157:H7. The molecular weight of the Verotoxin was found to be between 20 and 29 kD. The antibiogram profile of the four isolated strains against 10 standard antibiotics was determined.
Conclusion: The results of this study show the occurrence of drug resistance on hemorrhagic colitis causing E. coli O157:H7.

The Themes of 'Proactivity' and 'Reactivity' in Achebe's 'Marriage is a Private Affair'
Authors: Hussein Khalid Mahmoud
Published: April 2022

The present study sets out to investigate the themes of 'proactivity' and 'reactivity' in Chinua Achebe's 'Marriage is a Private Affairs'. First, definitions for these concepts are established, and then the main characters' responses which run in their speeches and actions are pored over considering these definitions. Throughout the present study, 'proactivity' and 'reactivity' are construed as conscious cognitive choices rather than personality traits and acting proactively or reactively (assertively or submissively) is beheld as contextually bound and as determined by what floats on the surface rather than by what hides in the unconscious. Drawing upon the critiques of the concepts of 'proactivity' and 'reactivity', and having in mind that 'proactivity' and 'reactivity', as their lexical meanings may suggest, are two ends for the same dimension of doing something, one could safely claim that despite all Nene's(a character) proactive efforts to cultivate friendship with her in-laws, only after going some way towards the traditional position and reacting positively to the socially- imposed patterns considered to be crucial determinants of her acceptance in the extended family network she is admitted in the cosmopolitan Ibo community. Finding her feet there, she partakes in the construction of a new more open and accommodating Ibo identity. Two other important themes that seem to emerge strongly in the present study are that marriage is a tribal matter that should be framed within allegiance and respect for family traditions and religious affiliation, and that family can tackle any problem if its members stand as one strong front against any external antagonistic power.
Digital Technologies and Social Media in Tourism
Authors: Gvaramadze Ana
Published: April 2022

Computer-mediated technologies allow individuals, companies, nongovernmental organizations, governments, and other organizations to view, create, and share information, ideas, career interests in virtual communities and networks. For the tourism industry it is essential to create interesting content on social media at all stages of the journey. The aim of the paper was to highlight the role of social media in the tourism industry, to reveal how mobile applications affect tourism, and how tourists benefit from using social networks while traveling. The purpose was to show the best practices in promoting consumer relations through social media and social media channels, and what role social media plays in many aspects of tourism, especially in terms of information retrieval and decision making. The research revealed which search engine Georgian tourists use to get information throughout their travel and whether they usually use social media platforms to buy a tourism product. Using qualitative and quantitative (population-based) methods, the results of the study showed that travellers in Georgia actively use social media for ideas and inspiration, at the same time to buy tourism products. Social media is not just about disseminating information, it can also influence tourists’ expectations and decisions. The research shows the importance of an online tourism domain in the context of travel planning through a search engine. Therefore, stakeholders in the tourism industry should pay attention to the impact of social media to improve the reliability of their information and services.

L’objectif de cette étude est d’évaluer l’effet de la BAP et de l’ANA sur les varaiations des teneurs en sucres solubles et acides aminés totaux dans les tiges des vitroplants du Manihot esculenta Crantz variété TMS 96/1762 au cours de la régénération in vitro. Pour ce faire, les bourgeons néoformés sur microboutures sont isolés sous la hotte à flux laminaire. Ils ont été ensuite repiqués dans des tubes de cultures contenant le milieu de régénération, constitué de MB  auquel on a ajouté 0,05/0,05 et 0,1/0,1 mg.l-1 BAP/ANA. Les sucres solubles et les acides aminés totaux ont été extraits selon la méthode de Saha et Brewer (1994) modifiée. Le dosage des sucres solubles a été effectué selon la méthode de Saha et Brewer (1994). Les acides aminés ont été  dosés à la ninhydrine selon la méthode de Yemm et Cocking (1995). Le milieu de culture favorable au microbouturage est le milieu MS + 0,1/0,1mg.l-1 BAP/ANA qui a permis d’obtenir un nombre moyen de feuilles maximal de 6,44 ± 1,89. L’addition de BAP/ANA (0,05/0,05mg.l-1) aux MB a entrainé une baisse de la teneur en sucres solubles. Elle est passée de 530,932 µg/g de PF au jour 7 à 507 µg/g de PF puis elle était devenue élevée jour 28 (684,152 µg/g de PF). L’utilisation de la combinaison BAP/ANA aux concentrations de 0,05/0,05 mg.l-1 et de 0,1/0,1mg.l-1 dans les MB a respectivement engendré des pics de la teneur en acides aminés totaux au jour 14 (101831,5 mg/g de PF) et au jour 28 (167948,7mg/g de PF).

The objective of this study was to evaluate the effect of BAP and NAA on changes in soluble sugar and total amino acid contents in stems of Manihot esculenta Crantz variety TMS 96/1762 during in vitro regeneration. For this purpose, buds neoformed on microbuds were isolated under the laminar flow hood. They were then transplanted into culture tubes containing the regeneration medium, consisting of MB to which 0.05/0.05 and 0.1/0.1 mg.l-1 BAP/ANA were added. Soluble sugars and total amino acids were extracted according to the modified method of Saha and Brewer (1994). The determination of soluble sugars was performed according to the method of Saha and Brewer (1994). Amino acids were assayed with ninhydrin according to the method of Yemm and Cocking (1995). The culture medium favorable for micro bottling was MS + 0.1/0.1mg.l-1 BAP/ANA, which resulted in a maximum average leaf count of 6.44 ± 1.89. The addition of BAP/ANA (0.05/0.05mg.l-1) to MB resulted in a decrease in soluble sugar content. It went from 530.932 µg/g FP on day 7 to 507 µg/g FP and then became high on day 28 (684.152 µg/g FP). The use of BAP/ANA combination at the concentrations of 0.05/0.05 mg.l-1 and 0.1/0.1mg.l-1 in MB resulted in peaks in total amino acid content at day 14 (101831.5 mg/g FP) and day 28 (167948.7mg/g FP), respectively.
Escuela de Artes Plásticas en Barranco: El Espacio “Inbetween” como Motor de Superación de un “Cringe” Cultural
Authors:   , Ferraro Ravettino Franco
Published: April 2022

Hoy, en el mundo del arte de Lima, se puede percibir un fenómeno social definido por Robert Hughes (1992) como “Cultural Cringe”. Dicho fenómeno se basa en la incapacidad que tiene el artista para fundamentar su obra en una sociedad en la que el consumidor se ve condicionado por una exposición constante a medios de comunicación masivos. Al parecer, la solución se encuentra en la propuesta de una Escuela de Arte en Barranco, escenario principal de dicho “Cringe”. Dicha casa de estudios debe poder ofrecer una educación integral, teórica y práctica, que permita que los alumnos sean competitivos en una realidad internacional y, eventualmente, debe permitir que el contexto social en el que se encuentra se vea contagiado por el conocimiento y la cultura que la misma imparte.
Key Considerations for Targeting Social Assistance in Situations of Protracted Crises
Authors: Sabates-Wheeler Rachel , Szyp Carolina
Published: April 2022

Targeting social assistance in situations of protracted conflict, protracted displacement, or recurrent climate shock, so that it reaches those most in need rapidly, effectively and without doing further harm, has historically been one of the most complex technical and political challenges for development and humanitarian programmes. Trade-offs involving costs beyond the economic – such as risks of exclusion and concerns over protection – raise questions about who to target, how to target and whether to target at all (i.e. through universal coverage or lotteries) would lead to better impacts in contexts where systems of state provision are often damaged or non-existent. The multiplicity of actors involved in delivering social assistance in crisis situations, with their own targeting cultures and mandates, can result in uncoordinated patchy and limited assistance, often overlooking equity concerns. Drawing on a range of literature, in this paper we examine the key considerations and dilemmas for targeting social assistance in protracted crises, including shock contexts, targeting methods, exclusion and protection risks, national and international actors’ politics, and technologies. Our purpose is to draw out lessons to better inform targeting of future social assistance programming across the humanitarian-development nexus.
Trends summarization of times series: a multi-objective genetic algorithm-based model

Published: April 2022

Aim: The explosion of the amounts of data generated in many application domains, makes the paradigm of data summarization more essential. Furthermore, it is of a great interest to effectively handle some specific needs. In this work, we discuss an advanced model to drive linguistic summarization in the context of time series. This model relies on a multi-objective genetic algorithm mechanism to generate a set of best summaries from a large number of candidates. Methods: To achieve this objective, the current work is divided into two parts: The first part is dedicated for extracting the linguistic summaries of the dynamic characteristics of the trends of time series. It is achieved using the traditional genetic algorithm where the fitness function represents the truth degree of the linguistic quantified proposition. The second part is devoted to formalise the problem of interest as a multi-criteria optimization problem. We use different quality measures of summary as targets for improving the predicted set of summaries. To reach this goal, we use the Fast Non-Dominated Sorting Genetic Algorithm NSGA-II. Results: We evaluate the proposed approach on real data from a Smart Campus application (Neocampus project of the University of Toulouse, France). The results are promising and confirming the usability of the proposed approach. Conclusion: The proposed approach overcomes the problem of the overabundance of irrelevant linguistic summaries of the time series. It allows selecting a set of best summaries regarding some relevant criteria.
Ecoepidemiology of dengue in Brazil: from the virus to the environment
Authors: Martins Ana Beatriz Souza , Alencar Carlos Henrique
Published: April 2022

Dengue is an infectious disease caused by the dengue virus. In Brazil, the main vector is the mosquito Aedes aegypti (L.); however, Aedes albopictus (Skuse) can also transmit this pathogen. According to the WHO, more than 125 countries are endemic for dengue, and an estimated 50-100 million infections occur annually. In Brazil, the Northeast region is one with high incidence rates and records of successive epidemics. Dengue has been circulating in Brazil for over 30 years, due to the fact that there are areas that offer favorable environmental conditions, as well as municipalities with low socioeconomic conditions and frequent water crises. In addition, Brazil is a tourist hub with an intense flow of visitors, keeping the doors open for the entry and circulation of vector-borne diseases. The role of epidemiology is to analyze the distribution of diseases and their determinants in space and time and to unveil the social inequalities that influence the health-disease process. Thus, a review study that describes the occurrence of Dengue may provide a perspective of future areas of greater risk for dengue epidemics.

De par les propriétés physiques et chimiques particulières du bois de chêne, une barrique est le siège de phénomènes de transfert très complexes. Grâce au développement d'un perméamètre gaz/liquide innovant, les flux d’oxygène de part et d’autre de la cellule ont été mesurés et un bilan matière complet sur la barrique a pu être réalisé. Au cours de ce travail de thèse, il a été démontré que le transfert d'oxygène se fait essentiellement à l'inter-douelle dans les zones de faibles pressions et le phénomène de désorption est prépondérant dans l'apport total d'oxygène.
