Bu çalışmada, Covid-19 salgını sürecinde okulların kapanmasıyla başlayan uzaktan eğitimin canlı derslerle yürütülmesinde ilkokul velilerinin yaşadığı sorunları ortaya koymak için betimsel bir araştırma yapılması amaçlanmıştır. Bu doğrultuda, 2019-2020 eğitim-öğretim yılındaki 313 ilkokul velisine çevrimiçi ortamda anket uygulanmıştır. Araştırma sonucunda velilerin çocuklarının canlı derse katıldıkları bilişim teknolojisi araçlarının donanımsal özelliklerinin ve internet bağlantısının iyi olduğu ancak buna rağmen canlı ders saatinde EBA’ya bağlantı sorunları yaşadıklarından dolayı EBA canlı ders uygulamasının alt yapısının yetersiz olduğu sonucuna varılmıştır. Veliler canlı ders sürecinde çocukların öğretim süreçlerine; öğretim ortamının hazırlanması, öğrenci motivasyonunu artırma, ödev yapımı ve kontrolünü sağlama, yapılan ödevlerle ilgili öğretmene dönüt verme olarak katkı sağlamaktadırlar. Velilerin %36,1’inin canlı dersler sırasında teknik anlamda sorun yaşadıkları; teknik sorun olarak da en fazla bağlantı sorunu/altyapı eksikliği sorunu yaşadıkları sonucuna varılmıştır. Velilerin %29.1’inin yönetimsel kaynaklı sorun yaşadığı; yönetimsel kaynaklı sorun olarak en fazla ders saati ve sayısının az olması, canlı ders veren öğretmenin süreç için hazır olmayışı ve isteksizliği ile canlı ders esnasında yaşanan iletişim eksikliğini dile getirmişlerdir. Velilerin 30.7’sinin canlı dersin en fazla sosyal etkileşim yanını sevdikleri; %35.8’inin planlama ve uygulama sorunlarını ise sevmedikleri belirlenmiştir. Bu bilgiler ışığında; velilere EBA canlı ders için sağlanan ücretsiz internetin diğer uzaktan eğitim platformlarını da kapsayacak şekilde genişletilmesi, canlı ders sürecinin sadece okul değil veli tarafından da dikkatlice yürütülmesi önerilmektedir.

Oral Squamous cell carcinoma (OSCC) is the most common oral malignancy which consistently ranks as one of the sixth most common cancer with significant morbidity and mortality. Oncogenic viruses, particularly Human Papilloma Virus (HPV) and Herpes simplex Virus (HSV) play an important role in the pathogenesis of OSCC. These viruses promote cell transformation and prompt uncontrollable cell generation, resulting in the formation of malignant tumors. The role of oncogenic viruses HPV, HSV in OSCC is presented.
INDIRECT SINUS LIFT
Authors: Rai Rathika , T.K Vidhya
Published: May 2022

The indirect sinus lift is a procedure to lift the augment/regenerate alveolar bone in atrophied residual maxillary posterior alveolar crest . The posterior maxilla is always considered as difficult site for the placement of implant than the mandible due to the presence of various anatomical land mark such as maxillary sinus. The anatomical structure of maxillary sinus often makes every dental implant surgeons a challenge task in placement of endosteal implants in the chronic atrophic maxilla and difficulty in osseointegration and further functional and aesthetic implant supported prosthesis. Various techniques in sinus lifting procedure enables the additional anchorage and stability in implants placed support in maxillary segments in with atrophic ridges and pneumatic sinuses. Lack of sufficient bone height along maxillary sinus poses significant difficulty for placement of implants in edentulous maxillary jaw. Minimally invasive sinus augmentation is an effective solution for this problem. In 1960 Boyne introduced sinus lift through lateral access which was initially used as a pre-prosthetic procedure for removable complete dentures purpose. In 1980 Boyne and James used the bone created by sinus lift procedures to place implants. In pursuit of less invasive techniques , in 1994 Summer’s explained a technique which offers access to sinus floor through residual alveolar crest. Using the elasticity of bone, floor dilatation of sinus was performed to increase the length of implants .

Published: May 2022

BACKGROUND: To develop an evidence based report on the level of knowledge and awareness about dental implants among public in South India through web–based questionnaire. So that this can be utilized for better understanding of patients’ needs and gain of knowledge among dental practitioners. MATERIALS&METHODS: A structured questionnaire survey was done to assess the level of knowledge and awareness about dental implants among the public through Google form. Two interviewers with dental background did the study, for a period of 4 months. All questions were close-ended multiple-choice questions. RESULTS: 1050 participants recorded their responses for this survey. Among them 566 (53.9%) are males and 484 (46.1%) are females, between age groups of 15-75 years. About 59.81% people have heard implant as a treatment procedure and 40.19% not aware, but on the contrary only 7.8% respondents have undergone an implant procedure. CONCLUSION: This survey reflects the clinical scenario of our day-to-day practice. Even though the patient knows of this dental treatment, many are not willing to undergo this procedure. The reason behind may be the fear of surgery or the cost of this treatment but it is in the clinician’s hands to improve this current situation in South India. Based on the result of our study, it is prudent for the clinician to put more effort in order to deliver efficient treatment protocols and glean this evidence to improve patient’s perception and acceptance for this treatment.

The conventional treatment for vertical maxillary excess due to Skeletal class II base, is surgical reduction and rigid fixation which has decreased patient acceptance. However, intrusion of some selected MVE cases can be achieved with minimal intervention using mini plate anchorage, thus expediting and simplifying their management. A 15 year old female patient came with a complaint of forwardly placed teeth in the upper front tooth region of the jaw. Intraoral examination showed class II molar occlusion on both sides with increased overjet and overbite. The cephalometric analysis showed class II skeletal relationship with vertical maxillary excess. The treatment plan included Fixed appliance with extraction of 14,24,35, then miniplates and miniimplant assisted anterior maxillary retraction and intrusion. At the end of the treatment anterior maxillary retraction and intrusion was achieved. Thus the hypothesis was accepted as retraction and intrusion using mini plates is an easy, efficient, safe and cost- effective option in the management of VME. It is less invasive with acceptable clinical and radiographic outcome, while avoiding surgery under GA with its risk and complication. Careful case selection is needed for achieving satisfactory result and smile.

Immediate implant is a valuable treatment of choice to replace non restorable teeth in the esthetic zone with a success rate of 87.5 to 100%. It has several advantages like minimizing the total treatment time, cost effective, and psycosocial benefits. In spite of the exceptional success rates, horizontal buccal bone resorption of about 56% and corresponding palatal bone resorption of 30% has been documented with respect to immediate implants (1) . These morphometric changes negatively influence the aesthetic outcome of dental implants. The use of modified surgical procedures such as the flapless technique, various hard tissue augmentation procedures, guided bone regeneration (GBR) and titanium reinforced barriers as well as various bone promoting molecules have been tried for bone preservation, with each method having its own benefits and drawbacks. Recently socket-shield technique (SST) otherwise called partial extraction therapy by Hurzeler et al in 2006 was described where buccal segment of the root is retained as a shield in situ, which aids in preserving periodontal attachment apparatus thus preserving the vascularity of buccal bone when compared to other conventional techniques. Here we present a case of non-restorable tooth in the maxillary aesthetic zone managed with placement of immediate implant using socket shield technique and evaluating the hard tissue health and aesthetic outcome (2).

Published: May 2022

The idiom CUP (carcinoma of unknown primary) is defined as the histological diagnosis of metastasis without the presence of a primary tumor. The prerequisites for the diagnosis of a CUP syndrome were defined as follows: biopsy and consecutive histological examination of a lymph node confirms malignant cell growth and makes a primary tumor at the location of the biopsy unlikely, while physical examinations and those carried out with technical equipment do not detect any primary tumor. There is an emergence of an occult primary in about 40% of CUP cases and about 70% of such lesions are detected in the head and neck region. in addition to thorough clinical examination of the head and neck mucosa (under general anesthesia), Positron emission tomography with fluoro-2-deoxy D- glucose is essential to identify or rule out the primary tumor, along with other modalities like CT/MRI, endoscopy and biopsy from all suspicious sites. Therapeutic approaches include neck dissection with or without post-operative radiotherapy, radiotherapy alone and radiotherapy followed by surgery

DOES TOLL LIKE RECEPTORS HAVE DOUBLE EDGE? : A REVIEW
Authors: C Vikram , M Shanmugam , D Smirithi , . Annie arokya mary
Published: May 2022

Vertebral immunity can be broadly classified into adaptive and innate immunity .Innate immunity is the first line of defense. Adaptive immunity are regulated by clonally distributed B and T lymphocytes and are characterized by specificity and memory .Innate immunity works through toll-like receptors (TLRs), which recognize the molecular patterns on virulent bacteria known as pathogen-associated molecular patterns(PAMP). The periodontium is constantly exposed to microorganisms which inturn stimulates the innate immune sytem. The toll like receptors present on gingival epithelial cells are continuously stimulated, resulting in production of cytokines and defensins that help to maintain oral health. If the epithelial barrier is breached, allowing invasion of bacteria into the underlying connective tissue, the TLRs on other resident and non-resident cells of the periodontium become activated. This leads to an exaggerated release of pro-inflammatory cytokines and other biological mediators, which may cause host tissue destruction. The present review examines the role of TLRs and their signaling in periodontal health and disease

Published: May 2022

An autoimmune bleeding disorder, formerly known as idiopathic thrombocytopenic purpura is characterized by isolated thrombocytopenia which is not associated with any other systemic illnesses. ITP in adults is often considered an autoimmune disorder, as the body produces antibodies that damage some of its own products-in this case, blood platelets. It is recorded that immune thrombocytopenic purpura occurs in about 2 in 1,00,000 adults. The course is more chronic although spontaneous remission can also occur within months of initial diagnosis. A thorough and timely workup of thrombocytopenia is necessary as it is considered as a diagnosis of exclusion to rule out other differentials of ITP. The present case report emphazises a case report and review on immune thrombocytopenic purpura in a 24- years old female who was identified in our hospital who visited for a normal dental screening

Published: May 2022

In this study, the inhibitory effects of extracts prepared from oleaster seeds on antioxidant activity, anti-urease and anti-collagenase enzyme activities, which have an important area in health, were investigated. For this purpose, the inhibitory effects of aqueous and methanolic extracts of these oleaster seeds on these enzymes were analyzed by spectrophotometric measurements. The inhibitory effect of the prepared extracts on these enzymes was evaluated by in vitro method. Only the aqueous extract was found to show both anti-urease and anti-collagenase activity. It was determined that it showed higher inhibition activity than the urease standard. Accordingly, the anti-urease IC50 value of the extract was 0.23 ± 0.003μg/mL; the % inhibition value at 2.8 µg/mL extract concentration was determined as 36.54 ± 1.11. Anti-collagenase IC50 value 2.8±1.12 μg/mL; the % inhibition value at 4.6 µg/mL extract concentration was determined as 50.7±0.01. The IC50 value of epigallocatechingallate anti-collagenase, which is the anti-collagenase standard, was determined as 1.05±0.002 μg/mL. DPPH and ABTS methods were used to examine the antioxidant activities of oleaster seeds extracts. According to DPPH results, while aqueous extract provided 25,85 % removal, the methanolic extract provided 20,44 % removal. In ABTS removal activity, while aqueous extract provided 25,55 % removal, the methanolic extract provided 18,23% removal. This study clearly shows that oleaster seeds the aqueous extract of can be used as an alternative source of anti-urease and anti-collagenase source. Due to the important role of these enzymes in various diseases, new drugs with inducing or inhibitory effects should be developed.

Published: May 2022

Bredia bullata, B. enchengensis, and B. nitida (Sonerileae, Melastomataceae), three species occurring in Sino-Vietnamese limestone karst regions, are described as new. Molecular phylogenetic analyses and morphological divergence indicate that these species are well separated from their close relatives in Bredia, justifying their recognition as distinct species. Bredia bullata is unique in its interveinal areas prominently bullate each with an apical seta, a character otherwise never recorded in the genus. Bredia nitida resembles B. malipoensis in habit, leaf shape, and inflorescence morphology, but differs in the glabrescent and nitid adaxial leaf surface (vs. densely pubescent and subvelvety), ovate-elliptic or elliptic calyx lobes (vs. triangular to semiorbicular), and white petals (vs. purplish-red). Bredia enchengensis is closest to B. longiradiosa, but easily recognized by its prostrate habit (vs. erect), the yellowish-green, membranous and fragile leaves (vs. green or dark green, papery), and white anthers (vs. pink to purplish). These new discoveries show that further botanical exploration is warranted in the remote Sino-Vietnamese bordering region.

Pour s’adapter à la marchandisation du droit et aux mutations profondes de leur environnement, les cabinets d’avocats d’affaires, constituant une composante désormais essentielle de l’avocature française, sont peu à peu devenus des entreprises de services juridiques. Mus par la rentabilité économique, ils développent des stratégies de marque pour se différencier dans un univers concurrentiel et diminuer l’incertitude liée à la qualité du service rendu. Comme dans d’autres secteurs d’activités économiques, ces marques mènent, à côté de la publicité classique, une communication dépublicitarisée. Cet article met en exergue leurs modalités et motivations d’appropriation de dispositifs médiatiques et culturels qui relèguent leur intention marchande au second plan.

Segmentation and identification of spectral and statistical textures for computer medical diagnostics in dermatology
Authors: Liu Xinlin , Krylov Viktor , Jun Su , Volkova Natalya , Sachenko Anatoliy , Shcherbakova Galina , Woloszyn Jacek
Published: May 2022

An important component of the computer systems of medical diagnostics in dermatology is the device for recognition of visual images (DRVI), which includes identification and segmentation procedures to build the image of the object for recognition. In this study, the peculiarities of the application of detection, classification and vector-difference approaches for the segmentation of textures of different types in images of dermatological diseases were considered. To increase the quality of segmented images in dermatologic diagnostic systems using a DRVI, an improved vector-difference method for spectral-statistical texture segmentation has been developed. The method is based on the estimation of the number of features and subsequent calculation of a specific texture feature, and it uses wavelets obtained by transforming the graph of the power function at the stage of contour segmentation. Based on the above, the authors developed a modulus for spectral-statistical texture segmentation, which they applied to segment images of psoriatic disease; the Pratt's criterion was used to assess the quality of segmentation. The reliability of the classification of the spectral-statistical texture images was confirmed by using the True Positive Rate (TPR) and False Positive Rate (FPR) metrics calculated on the basis of the confusion matrix. The results of the experimental research confirmed the advantage of the proposed vector-difference method for the segmentation of spectral-statistical textures. The method enables further supplementation of the vector of features at the stage of identification through the use of the most informative features based on characteristic points for different degrees and types of psoriatic disease.
Asymptotic behavior of the solutions for a stochastic SIRS model with information intervention
Authors: Ding Tingting , Zhang Tongqian
Published: May 2022

In this paper, a stochastic SIRS epidemic model with information intervention is considered. By constructing an appropriate Lyapunov function, the asymptotic behavior of the solutions for the proposed model around the equilibria of the deterministic model is investigated. We show the average in time of the second moment of the solutions of the stochastic system is bounded for a relatively small noise. Furthermore, we find that information interaction response rate plays an active role in disease control, and as the intensity of the response increases, the number of infected population decreases, which is beneficial for disease control.

Published: May 2022

New Delhi metallo-β-lactamase-1 (NDM-1) producing Pseudomonas aeruginosa strain detection plays a vital role in confirming bacterial disease diagnosis and following the source of an outbreak for public health. However, the standard method for NDM-1 determination, which relies on the features of the colony of the bacteria cultured from the patient's specimen, is time-consuming and lacks accuracy and sensitivity. This study aimed to standardize a high-resolution melting curve analysis (HRMA) assay to detect NDM producing P. aeruginosa. For optimization and development of the HRMA method, a reference strain of P. aeruginosa was used. For evaluating the broad range PCR data, ABI Step One-Plus Manager Software version 3.2 and Precision Melt Analysis Software 3.02 (Applied Biosystems) were used.

Based on the results, expected results were obtained for all tested strains, with high analytical sensitivity and specificity. Temperature melting analyses of the HRMA time PCR assays showed the Tm at 89.57 °C, 76.92 °C and 82.97 °C for N-1, N-2 and N-3 genes, respectively. Also, melting point temperatures of the blaVIM, blaSPM and blaSIM amplicons for isolates identified as MBL strains were 84.56 °C, 85.35 °C and 86.62 °C, respectively. The amplification results using negative control genomes as templates were negative, showing the specificity of the designed assays. Our study's data indicated that the sensitivity and specificity of the HRMA method are linked to the primer length and the fluorescent dye. We can further identify antibiotic resistance in NDMproducing P. aeruginosa by software analysis and melting curve analysis.
Isoparametric foliations and the Pompeiu property
Authors: Provenzano Luigi , Savo Alessandro
Published: May 2022

A bounded domain $ \Omega $ in a Riemannian manifold $ M $ is said to have the Pompeiu property if the only continuous function which integrates to zero on $ \Omega $ and on all its congruent images is the zero function. In some respects, the Pompeiu property can be viewed as an overdetermined problem, given its relation with the Schiffer problem. It is well-known that every Euclidean ball fails to have the Pompeiu property while spherical balls have the property for almost all radii (Ungar's Freak theorem). In the present paper we discuss the Pompeiu property when $ M $ is compact and admits an isoparametric foliation. In particular, we identify precise conditions on the spectrum of the Laplacian on $ M $ under which the level domains of an isoparametric function fail to have the Pompeiu property. Specific calculations are carried out when the ambient manifold is the round sphere, and some consequences are derived. Moreover, a detailed discussion of Ungar's Freak theorem and its generalizations is also carried out.
Impact of risks on forced CEO turnover
Authors: Chang Xue
Published: May 2022

Risk management has been an important topic since the 2008 financial crisis, and it has become an important area of focus in business management. It is important for the board of directors to evaluate the ability and competence of the CEO. This study was aimed to investigate the effect of various risks on forced CEO turnover through the use of a linear probability model. The Chinese A-share market from 2010 to 2019 was selected as the sample, and theoretical analysis and empirical research were combined to explore the impact of various risks on forced CEO turnover, further analyzes the relationship under different ownerships. This paper study revealed that the crash risk is positively associated with forced CEO turnover. This paper also found that the idiosyncratic risk increases the likelihood of forced CEO turnover, and that the relationship is more significant in non- state-owned enterprises (non-SOEs) than state-owned enterprises (SOEs). The systematic risk has no effect on forced CEO turnover. Risks can be an important indicator of the CEO's ability and competence. This paper also evaluated the relationships in Chinese circumstances. China is an emerging market that has a different legal and social environment than other countries. The different goals of SOEs and non-SOEs lead to different risk attitudes. It is necessary to distinguish ownership when evaluating the Chinese situation.
Artificial Reef Stakeholders in France: A Social-Network Analysis
Authors: Salaün Jessica , Pioch Sylvain , Dauvin Jean-Claude
Published: May 2022

As coastal zones are subjected to cumulative human pressures, it is vital to protect these productive and sensitive marine ecosystems. Artificial Reefs (ARs) are recognized as useful tools to overcome certain challenges to these ecosystems, if managed and regulated appropriately. While ARs were originally used for fishery purposes, for almost two decades they have also been widely used in ecological restoration to recover specific habitat functions. Most assessments of ARs focus on their biological and physical results: few have investigated how stakeholders contribute to their outcome. This chapter seeks to shed light on this aspect, examining the role and characteristics of stakeholders in ARs using social network analysis.
Artificial Reef Contributions to Sustainability

Published: May 2022

For 59 million people in the world, fishing represents their main source of income. In addition, for 3.2 billion people, fishery resources provide 20% of the protein of animal origin in their diet. One tool that could contribute to recovering stocks in a sustainable way is artificial reefs. In Mexico, 750 structures were deployed in Barra de Pichi and 500 in Caleta de Campos municipality of Lázaro Cárdenas, Michoacán, between 2016 and 2018. The objective of this work is to evaluate the level of sustainability of the artisanal fishing system between Barra de Pichi and Caleta de Campos, in relation to the artificial reefs (ARs) and with the purpose of assessing its usefulness as a public policy tool. The framework for the evaluation of natural resource management systems incorporating sustainability indicators (MESMIS) was used as a methodological guide, comparing two groups: AAusers (users ARs) and non-AAusers (non-users of ARs). The results showed that the artisanal fishing activity carried out by ARs users is more sustainable than non-ARs users.
An Overview of the First National Artificial Reef Project of Turkey

Published: May 2022

Although artificial reef applications in Turkey started in the 1980s, the acceptance of its use as a tool in fisheries management ended in the 2000s. The first legal regulation on artificial reefs entered into force in 2001, and the National Artificial Reef Program (NARP) was prepared in 2009. The program was aimed to have two main purposes: (1) create new fishing grounds to promote small-scale fisheries and (2) conserve biodiversity in the littoral zone. The first pilot project within the framework of the NARP was completed in February 2013 in Edremit Bay. With the completion of the deployment of the ARs, a 5-year monitoring program was initiated. In this chapter, the historical development of AR studies in Turkey, the NARP, and the evaluation of the first project within the framework of the program are discussed.
Portuguese Artificial Reef Modules
Authors: Ramos Jorge H. P.
Published: May 2022

Artificial reefs (AR) for diving must have certain characteristics that are not activity-limiting. Likewise, these characteristics are generally fundamental for good diving experiences. In this aspect, AR must not be at a great depth, and they must have a diverse bio-colonization by several species of various taxa and attract diver interest. In Portugal, Algarve (South) and Nazaré (Centre) reef modules were deployed at depths that can be considered as potential for diving. In this chapter, an approach is made using the analytic hierarchy process (AHP) and fuzzy logic (a method called fuzzy analytic hierarchy process: FAHP) defining what is the likely interest for potential diving tourism activities in each of the locations presenting AR modules. The results obtained by using these methods allowed to further discover the importance of AR in Algarve and Nazaré.

Situating Cultural Awareness Through Comics
Authors: DeHart Jason D.
Published: May 2022

This chapter explores the affordances of the comics/graphic novels medium for engaging in critical reading and awareness of relevant cultural issues and a range of experiences. The author situates comics as medium before highlighting the work of Faith Erin Hicks, noting both promise and limitation in the graphic novel series The Nameless City as a way of beginning conversations about relevant topics. The attention then shifts to include the work of Nate Powell, framed as artivism, and the adaptation process of moving the verse novel work of Jason Reynolds to graphic novel form. In this section, the author invites the collaboration of the artist who crafted the adaptation. Finally, attention is given to additional titles that teachers and researchers can consider.
The Red Bandanna
Authors: Worley Cristina
Published: May 2022

Teachers often think of curriculum as a static set of written content. However, in college level multicultural education (ME) classes, this kind of curriculum rarely provides the student input necessary for authentic transformation. As a result, pre-service teachers lack the ability to understand how their biases and assumptions negatively impact their students. This phenomenon coupled with pre-service teachers' negative associations with terms like “white privilege” and “deficit perspective” beg the question: How can White educators provide positive experiences that result in high levels of cultural competence among White teachers, who make up the workforce majority? With this question in mind, the author set out to create the “red bandanna experiment,” a lived curriculum-as-racialized-text experience in present time that relies on both teacher and student input. Ultimately, the experiment allowed for her own critical engagement with curriculum artifacts and also gave students a positive outlet for engaging with their own biases and assumptions.
The Concept of Corporate Social Responsibility
Authors: González-Masip Jaime
Published: May 2022

The concept of corporate social responsibility continues in a state of lack of academic consensus, which makes it difficult to propose new research proposals on the company's social and environmental commitment. With the aim of facilitating research tasks, this chapter systematically compiles a list of definitions of the concept and lists a set of dimensions or drivers that are either present in these definitions or can be considered as fundamental elements or perspectives for the study of corporate social responsibility. As conclusions, the most relevant ideas presented in the chapter are compiled. The incorporation, in academic studies, of perspectives based on impacts of business activity rather than principles of action is also proposed, since they present a possible greater operability. These concepts are corporate social performance or corporate sustainability.

Corporate Social Responsibility and Financial Information
Authors: Gavancha Irina Filipa , Paiva Inna Sousa
Published: May 2022

The importance of corporate social responsibility (CSR) has been increasing especially in the last decade, due to the positive pressure exerted by society in general. This chapter analyses the relevance of CSR, associated theories and studies carried out in the last decade related to financial information and consequently accounting quality. The strong link between CSR and financial information that is directed towards knowledge of mitigation of asymmetry information is evident. We aim to contribute to the development of sustainability accounting, presenting assumptions that mitigate the blocks of practice of CRS acts that make the return of positive elements possible, namely the image of entities and their financial economic improvement.
