Symptoms or behaviors called symptomatic by Steiner (2004) explain how interactions in the classroom only look at the physical presence around teachers and students. However actually, intrinsic value is very crucial to prioritize. The intrinsic value in students who need to be touched is their heart and soul to get to know each other better. Teaching classically with the view that the existence and readiness of students are the same is a way of thinking that should be addressed to present an unpretentious "open classroom climate" filled with love, care, and togetherness.
A memoritertanulás és a digitális oktatás az anyanyelvi nevelésben
Authors: Urbán Péter
Published: May 2022

A memoriterek problémája a magyar nyelv és irodalom tantárgy aktuális tantárgy-pedagógiai dilemmáinak egyfajta kicsinyítő tükre. A tanulmány ezek közül a problémák közül azoknak a körüljárására vállalkozik, amelyek sajátos módon egybeesnek a digitális tanulási környezetek professzionális tervezésének sürgető kihívásaival. A memoriter olyan területek reflexiójára késztet, mint a magyarórán szerzett tudás tartalma és minősége, az irodalom és a nyelv viszonya, a tantárgyi tevékenységekhez, különösen az olvasáshoz kapcsolódó attitűdök formálása. A memoriter a felületesebb gondolkodás számára több szempontból is ellentmondásosnak tűnhet. A régebbi korok pedagógiájának öröksége ugyanakkor a korszerű neveléstudományi paradigmákban is pozitív fogadtatásra talál. A külső tárolók és ezek modern mobilitása fölöslegessé teszik, éppen ez a fölöslegessé válás eredményezi azonban mégis sajátos nélkülözhetetlenségét. Ez a paradox helyzet meggyőzhet mindenkit arról, hogy a korszerű technológiára nem csupán úgy érdemes gondolnunk, mint ami helyettesít valamit, hanem úgy is, hogy talán éppen a helyettesítés lehetősége növeli meg a helyettesített jelentőségét.
Philosophical Dialogue in the Works of Joseph de Maistre and Vladimir Solovyov (St. Petersburg’s Evenings and Three Conversations: the Comparative Analysis Experience)
Authors:   National Research University Higher School of Economics, Parsamov Vadim S.
Published: May 2022

The article examines the reflection of the philosophical ideas of the “St. Petersburg’s Evenings” by Joseph de Maistre in “Three Conversations” by Vladimir Solovyov. Both of these works, created in the genre of philosophical dialogue, are the final works of their author. Solovyov and Maistre reflect on the same problems of evil and violence, war and peace, the end of world history. Solovyov's ideas are largely polemical in relation to those of Maistre. Maistre is interested in the question of the origin of evil and the responsibility of God for it. For Solovyov, the problem of resistance to evil is more important. In this respect, he takes an intermediate position between L. Tolstoy with his idea of non-resistance and Maistre with his idea of resistance to violence by forse. Solovyov considers good to be the only means of resisting evil, which in some cases does not exclude violence. In matters of war and peace, Solovyov also takes an intermediate position between Tolstoy’s pacifism and Maistre’s view of the divine origin of war as a punishment for people. Solovyov does not consider war an absolute evil, just as he does not consider peace an absolute good. War, from his point of view, is the creation of people, but it is justified and necessary when it is waged in defense of Christianity. In questions of the end of world history, Solovyov polemics with the idea of the third Testament, which goes back to the teachings of Joachim of Flores, which is expressed by Maistre. In the ideological structure of “Three Conversations”, Maistre takes the place of Tolstoy's antipode. Their ideas are presented to Solovyov as two abysses that distort the truth in opposite directions.
The Phenomenon of Reproducibility from the Point of View of Epistemology and Philosophy of Science
Authors:   Ulyanovsk State University, Bazhanov Valentin A.
Published: May 2022

The article analyzes the phenomenon of reproducibility (repeatability, replica­tion), its terminological variations and grounds for assessing the current stage of development of science as a crisis in terms of reproducibility (verification) of scientific research results and their acquisition of intersubjective status. Attention is drawn to the fact that judgments about the crisis of reproducibility apply to al­most all areas of science, including such (often called exact) sciences such as physics and chemistry. We claim that understanding the phenomenon of repro­ducibility directly affects decision-making policy towards science (regulation of the activity of scientific directions and their funding). At the same time, the situ­ation in the social, humanitarian and biomedical sciences is of particular con­cern, since the level of reproducibility here is quite low. This applies to modern neuroscience as well. From the point of view of epistemological view, it is pro­posed to interpret reproducibility procedures as an attempt to overcome funda­mental limitations associated with measurement processes. It is shown that un­derstanding the meaning and significance of these procedures depends on the opinion of the disciplinary scientific communities, which differ in their ap­proaches to the criteria of reproducibility and follow different cognitive tradi­tions and attitudes. It is emphasized that in the social and humanitarian fields of knowledge it is necessary to take into account the “contextuality” of the mea­surement process, the constant and inevitable dynamics of the characteristics of society, culture and the person himself. All this push us to think about the prob­lem of defining the boundaries of de-anthropologization of scientific knowledge. An attempt is made to comprehend the phenomenon of reproducibility through the lens of the interval approach, and it is stated that reproducibility (ontologi­cally) is limited by the “pervasive inaccuracy of the real world” (L. Zadeh).
What is the Philosophy of Dialogue? Historical Interaction of Different Schools
Authors:   Hebrew University of Jerusalem, World Center for Jewish Studies, Dvorkin Ilya S.
Published: May 2022

To answer the question “what is the philosophy of dialogue” it is necessary to solve two interrelated tasks: to define the main group of its authors and to iden­tify the main part of its content. During the century of development of the phi­losophy of dialogue, several centers of its consolidation can be distinguished. The first most famous such center is the group of dialogists in Germany in the 1920s. It is with the ideas of Rosenzweig, Buber, Ebner, Rosenstock-Huessi that the philosophy of dialogue is associated in the first place. Along with this, it is necessary to consider the independent center of the philosophy of dialogue in Russia, which is primarily associated with the name of M.M. Bakhtin. The pres­ence of a philosophy of dialogue as a unified direction essentially depends on the extent to which these two schools can be considered as one entity. At the same time, many researchers note the presence of a common source for these centers in the philosophy of H. Cohen, which, although not considered by its author as a philosophy of dialogue, contained important prerequisites of the latter. These three centers of consolidation served as a source for a number of dialogical teachings, which more or less independently developed during the 20th century in Germany, France, the Soviet Union, the USA and Israel (H. Levin Gold­schmidt, E. Levinas, V.S. Bibler, etc.). In addition to the continental branch, at the end of the 20th century, the analytical-pragmatic movement of the philo­sophy of dialogue appeared in works of K.-O. Apel, J. Habermas, K. Lorenz, P. Lorenzen. All these authors are characterized by the view of reality as a process of interaction between persons, the priority of language in relation to thinking, the study of the deep connection of social processes with dynamics of interper­sonal relations. In this article, we consider the forms of comprehension of the listed topics in different schools of philosophy of dialogue in historical dy­namics. This allows us to talk about the philosophy of dialogue as a single move­ment of thought.
Cognitive Basis of Legal Order

Law as a special social regulation tool in modern conditions acquires a universal character. For its comprehensive study, as well as for its implementation in public life, a special cognitive apparatus is required. Consequently, both in theoretical and practical terms, it is about legal thinking, which is in the focus of doctrine as a special form of mental activity. To solve scientific problems associated with this study, it is advisable to introduce the category of “cognitive basis of law and order” into science. This kind of innovation is necessary in order to disclose a mechanism for ensuring trust in society, without which the entire apparatus of legal coercion is reduced to haphazard violence and, as a result, becomes meaningless. This mechanism includes intellectual and volitional components. The former is the dominant component, as it is represented by the “cognitive apparatus of law”. It is this component which deter­mines the entire “content of law”, while ensuring its consistency, independence and completeness. The inclusion of the volitional component in the cognitive basis of law and order is explained by the fact that it is through this component the intellect is re­alized. Without an act of external expression of will none of intellectual activity in the field of law can achieve its goals. The cognitive basis of the rule of law – in conjunction with its normative and institutional foundations – ensures the func­tioning of law, while defining its existence.

Published: May 2022

Severe Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV-2) has now spread worldwide, and various governments are attempting to control the disease's spread before it becomes a global health crisis. Data from 28 Indian states and 8 Union Territories (UTs) provide a detailed look at the transmission pathways and case fatality rate (CFR) of the SARS-CoV-2. Among the global data, India was found to be the third country with the highest mortality cases of 157K, and Maharashtra was having the most higher number of mortality cases followed by Tamil Nadu and others. The percent distribution of CFR calculated in each geographical zone of India i.e. Central, Eastern, North Eastern and Northern, Southern and Western zone were 17%, 14%, 7%, 22%, 12%, and 28%, respectively. Furthermore, the CFR was calculated at different periods of the month using a standard formula. The CFR was significantly higher (P<0.01) in April to June of 2020. CFR was significantly different (P<0.01) depending on the month. Moreover, CFR was compared in different zones in India, western zone showed the highest CFR as compared to other zones. The effectiveness of SARS-CoV-2 was evaluated in patients of various ages and co-morbidities. Patients >21 years had the highest age-specific positivity rate. The prevalence of SARS-CoV-2 patients in acute and chronic disease was 12.87 and 87.13 percent, respectively. Thus, this analytical epidemiological study serves specifically in establishing a relationship between SARS-CoV-2 infection and other precipitating factors causing morbidity and mortality during the given time frame in the first wave, in the year 2020.

Published: May 2022

Background
Premature ovarian failure which leads to loss of fertility and low level of estrogen have serlously affected women's physical and mental health, especially, women of child-bearing age. The etiology remains unclear. DNA methylation, as a key epigenetic modification might play an importan role in primary ovarian insufficiency (POI). We explore the whole DNA methylation of POI by whole genome bisulfite sequencing (WGBS), and find the pattern of DNA methylation in POI and analyze the differentially methylated regions (DMRs) genes related POI.
Methods
According to clinical and experimental standards, follicular fluid samples were collected from three women with POI and three women with normal ovarian reserve (NOR). Ovarian granulosa cells were purified from each follicular fluid sample. Whole genomic DNA methylation sequencing of the granulosa cells was performed by WGBS.
Results
We obtained whole-genome methylation maps of human granulosa cells. The average percentages of methylated cytosines in CG contexts exceeded 99%, in CHG and CHH contexts was less than 1%. The average methylation level in CG was about 80%, in CHG and CHH was less than 0.4%. there was no significant difference in CpG methylation level between NOR and POI. But there were DMRs between two groups. Distribution of DMRs was enriched in promoter and exon. Differentially methylated genes were used to perform Gene ontology(GO) analysis and enriched in GO items of cellular process, biological regulation, metabolic process, developmental process,binding and catalytic activities.
Conclusion
DNA methylation plays a critical role in POI and serve as resources for further investigation in the future.
Sediment Yield Modelling and Soil Erosion Hotspot Area Identification
Authors: Sime Chala Hailu , Abebe Wondmagegn Taye
Published: May 2022

Sediment movement is the most critical problem in Ethiopia, notably in the Ketar river watershed, which is located in the Rift Valley Basin. The Ketar River flows through rugged terrain with steep slopes and high sediment movement. The purpose of this research is to check Soil and Water Assessment Tool (SWAT) in simulating sediment yield and to identify soil erosion-prone sites. The SWAT model sediment simulation performance was evaluated using the coefficient of determination (R2) and Nash-Sutcliffe Efficiency (NSE), with R2 and NSE values of 0.69 and 0.55 for calibration and 0.73 and 0.51 for validation, respectively using SWAT Calibration and Uncertainty Program (SWAT-CUP). The sub-basins located at the upstream of the watershed have a high sediment yield rate. The sediment-prone area sub-basins have steep slopes and were mostly covered by cultivated land. Annual sediment yield from cultivated land was approximately 1872.12 t/y, while grass land with moderately cultivated yield was 171.45 t/y. Woodland and forest land have less soil erosion rate. The sub-basin highly covered by Eutric nitisols is found at very high soil erosion prone area. Sediment yield from a slight slope is almost zero, whereas sediment yield from steep and very steep slopes was very high. The slope of the sub-basin is an important factor in determining sediment yield, followed by land cover and soil types. The very high sediment yield rate area accounted for 39.64% of the total sub-basin.

Published: May 2022

PURPOSE
This study proposes a novel Maximum Likelihood Expectation Maximization (MLEM) based positron emission tomography (PET) image reconstruction approach, designed to provide improved signal recovery, specifically in small structures. This proposed technique, termed GPSF-MLEM, utilizes a gradually decreasing full-width-half-maximum (FWHM) point spread function (PSF), designed to yield increased spatial details in progressing iterations when measured and estimated projection data are in closer consensus.
METHODS
GPSF-MLEM was compared with the analytical filtered back projection (FBP) and the iterative reconstruction techniques of standard MLEM and PSF incorporated into MLEM (PSF-MLEM). Simulated phantoms as well as cylindrical and brain phantoms were used to evaluate performance, contrast recovery and for visual assessment of image quality. The performance of GPSF-MLEM and PSF-MLEM with various FWHM kernel sizes was also investigated. This work presents evidence that the choice of reconstruction technique and parameters for the best quantification of reconstructed PET images should be based on the purpose (task-based optimization).
RESULTS
Quantitatively, across all reconstructions tested, the image intensity estimated using GPSF-MLEM terminated at an intermediate FWHM was in closest agreement to the raw image intensity in the simulated phantom. Qualitative analysis of reconstructed images with physical phantoms suggested that irrespective of the FWHM at the terminal iteration, GPSF-MLEM provided robust image contrast and increased suppression of background hotspot artifacts compared to MLEM and PSF-MLEM. Further, across all FWHM combinations tested, GPSF-MLEM yielded fewer artifacts inherent to PSF-MLEM images reconstructed with an overestimated FWHM.
CONCLUSIONS
Emphasizing common task scenarios frequently encountered in medical imaging: A) GPSF-MLEM is recommended for tasks requiring a low background noise; B) PSF-MLEM is recommended for tasks that require good image segmentation; C) GPSF-MLEM with a larger terminal FWHM is recommended for obtaining high contrast recovery in small image structures.
Correlation between accuracy in computer guided implantology and peri-implant tissue stability: a prospective clinical and radiological pilot study
Authors: Poli Pier Paolo , Manfredini Mattia , Maiorana Carlo , Beretta Mario
Published: May 2022

Background there is very little scientific evidence in the literature regarding the correlation between accuracy and peri-implant health. Consequently, the present pilot study was designed to fill this gap in the literature, hypothesizing a possible correlation between lack of accuracy in implant placement and deterioration of peri-implant hard and soft tissue health.Materials and Methods a total of 5 male and female patients were enrolled. Patients underwent computer-guided implant surgery and full arch immediate load between 2013 and 2014. After a follow-up of 5 years, all patients treated with the computer-guided implant placement technique and undergoing evaluation of the accuracy of computer-guided implant placement by postoperative CBCT were recalled for a clinical-radiographic evaluation of peri-implant health status. Accuracy of implant placement was then related to peri-implant hard and soft tissue health variables such as marginal bone resorption, amount of keratinized tissue, recession and plaque and bleeding.Results Mean linear deviation was 0.57 ± 0.23 mm at implant head and 0.69 ± 0.26 mm at implant apex, while mean angular deviation of the long axis was 2.88° ± 1.22°. A mean MBL of 1.16 ± 0.94 mm and 2.01 ± 1.76 mm was observed after 1 and 5 years of follow-up, respectively. At 5 years, mean PPD was 4.09 ± 1.44 mm, 66.6% of the evaluated implants showed BOP, KM was < 2 mm in 48.4% of cases, REC ≥ 1 mm was assessed in 45.4% of the included implants, plaque accumulation occurred in 66.6% of cases. A negative correlation was observed between bucco-palatal/lingual linear inaccuracy and MBL, PPD, BOP and KM.Conclusions with the limit of a pilot study, it can be observed that the accuracy of computer-guided implant surgery as described here, obtained satisfactory results. A reduction in accuracy leading to the placement of an implant in an excessively vestibular position may be the cause of peri-implant hard and soft tissue suffering in terms of marginal bone resorption, amount of keratinized mucosa and bleeding on probing.

Published: May 2022

Background: Rapid referral of traumatic brain injury (TBI) patients requiring emergency neurosurgery to a specialized trauma center can significantly reduce morbidity and mortality. Currently, no model has been reported to predict the need for acute neurosurgery in severe to moderate TBI patients. This study aims to evaluate the performance of Machine Learning based models to establish to predict the need for neurosurgery procedure within 24 hours after moderate to severe TBI.Methods: Retrospective multicenter cohort study using data from a national trauma registry (Traumabase®) from November 2011 to December 2020. Inclusion criteria correspond to patients over 18 years old with moderate or severe TBI (Glasgow coma score ≤ 12) during prehospital assessment. Patients who died within the first 24 hours after hospital admission and secondary transfers were excluded. The population was divided into a train set (80% of patients) and a test set (20% of patients). Several approaches were used to define the best prognostic model (linear nearest neighbor or ensemble model). The Shapley Value was used to identify the most relevant pre-hospital variables for prediction. Results: 2159 patients were included in the study. 914 patients (42%) required neurosurgical intervention within 24 hours. The population was predominantly male (77%), young (median age 35 years [IQR 24-52]) with severe head injury (median GCS: 6 [3-9]). Based on the evaluation of the predictive model on the test set, the logistic regression model had an AUC of 0.76. The best predictive model was obtained with the CatBoost technique (AUC: 0.81). According to the Shapley values method, the most predictive variables in the CatBoost were a low initial Glasgow coma score, the regression of pupillary abnormality after osmotherapy, a high blood pressure and a low heart rate. Conclusion: Machine learning based models could predict the need for emergency neurosurgery within 24 hours after moderate and severe head injury. Potential clinical benefits of such models as a decision-making tool deserve further assessment. The performance in real-life setting and the impact on clinical decision making of the model should be evaluated in prospective studies.
Optimized deep learning model for spatio-temporal detection and localization of object removal video forgery with multiple feature extraction
Authors: Ch Lakshmi Kumari , K.V PRASAD
Published: May 2022

Video forgery (VF) is an approach for manipulating the fake videos by modifying, coordinating or generating new contents among the video sequence. The identification of this type of video forgery is complex. For extracting multiple features, developing a novel approach still remains major challenge in this area. In this work, an optimized deep learning (DL) model for the video forgery detection (VFD) and localization with multiple feature extraction is proposed. Initially, key-frame extraction takes place with the aid of Gaussian mixture model (GMM) to extract frames from the forged videos. Then, pre-processing stage is manipulated for the conversion of RGB frame into grayscale image. To study the nature of the forged videos, there is a need of extracting multi-features from the pre-processed frames. In our proposed study, SURF, PCA-HOG, MBFDF, COA and PRG features are extracted. The dataset used for proposed work is collected from REWIND of about 80 forged and authenticated videos. With the help of DL approach, video forgery can be detected and localized. Thus, this research mainly focus on the detection and localization of forged video based on ResNet152V2 model hybrid with Bi-GRU to attain the maximum accuracy and efficiency. The performance of this model is finally compared with existing approachesin terms of accuracy, precision, F-measure, sensitivity, specificity, FNR, FDR, FPR, MCC and NPV. The proposed methodology assures the performance of96.17% accuracy, 96% precision, 96.14% F-measure, 96.58% sensitivity, 96.5% specificity, 0.034 FNR, 0.04 FDR, 0.034 FPR, 0.92 MCC, 96% NPV respectively. Along with is, the mean square error (MSE) and peak-to-signal-noise ratio (PSNR) for GMM model attained about 104 and 27.95 respectively.

Published: May 2022

Background: Metabolic syndrome (MetS) is characterized by a cluster of signs of metabolic disturbance and has caused a huge burden on the health system. The study aims to explore the prevalence and characteristics of MetS defined by different criteria in the Chinese population.Methods: Using the data of the China Hypertension Survey (CHS), a nationally representative cross-sectional study from October 2012 to December 2015, a total of 28717 participants aged 35 years and above were included in the analysis. The MetS definitions of the International Diabetes Federation (IDF), the updated US National Cholesterol Education Program Adult Treatment Panel III (the revised ATP III), and the Joint Committee for Developing Chinese Guidelines (JCDCG) on Prevention and Treatment of Dyslipidemia in Adults were used. Multivariable logistic regression was used to identify factors associated with MetS.Results: The prevalence of MetS diagnosed according to the definitions of IDF, the revised ATP III, and JCCDS was 26.4%, 32.3%, and 21.5%, respectively. The MetS prevalence in men was lower than in women by IDF definition (22.2% vs. 30.3%) and by the revised ATP III definition (29.2% vs. 35.4%), but the opposite was true by JCDCG (24.4%vs 18.5%) definition. The consistency between the three definitions for men and the revised ATP III definition and IDF definition for women was relatively good, with kappa values ranging from 0.77 to 0.89, but the consistency between the JCDF definition and IDF definition (kappa = 0.58) and revised ATP III definition (kappa = 0.58) was poor. Multivariable logistic regression showed that area, age, education, smoking, alcohol use, and family history of cardiovascular disease were factors related to MetS, but the effects and correlation intensity of these factors varied with gender and definition.Conclusions: The prevalence and characteristics of the MetS vary according to the definition used in the Chinese population. The three MetS definitions are more consistent in men but relatively poor in women. On the other hand, regardless of the definition used, metabolic syndrome is common in China, so it is necessary to take targeted measures to reduce its harm.

Published: May 2022

Background
The onset of COVID-19 has led to people adopting either facility-based care or herbal medication. The Ugandan government allowed for this two-tier system of care, yet little is known as to why people during the COVID-19 choose the type of care that they do. There is also little known regarding the actual lived experiences of the people that choose facility-based treatment or herbal care. There is lack of evidence to understand the complex choices and experiences of people adopting either of the two options during COVID-19 crises in Uganda. This study attempts to fill this gap by investigating people’s experiences with choosing either facility-based treatment or herbal treatment. Understanding factors that drive the usage, fears, and trust of the population in different treatment options is necessary for the adoption of effective policy.
Methods
A qualitative study with a sample size of 333 was used for this study. Thematic analysis with the help of the Social Representation Theory (SRT) provided the basis of analysis.
Results
We set out to investigate people’s experiences and views regarding why they choose either facility or herbal based treatment against COVID-19. With the help of the SRT, the study showed that easy accessibility, affordability, trust in traditional knowledge and the official authorization of Covidex as factors leading to a positive perception of herbal treatments. On the other hand, the lack of regulation and a clear dosage as well as international recognition were found to create a negative perception of herbal treatment. Regarding facility-based treatment, the trust in the scientific development, regulation and international authorization as well as in the medical personnel could be identified as the main factors leading to a positive perception. The negative perception of facility-based treatment was mostly created based on the fear of side effects, the contraction of COVID-19 in the health facilities as well as the low accessibility and high costs.
Conclusion
Ultimately, our study provides evidence of how each type of treatment produces complex experiences among the population. Thus, this study defies any binary notions of “either good or bad” regarding the two types of treatment. Rather, our evidence shows the complexity in pull and push factors regarding the adoption of any of the two options. This means any policy on improving treatment of COVI-19 in Uganda must pay particular attention to how these factors interplay and interrelate.

Background
Against the background of e-government, it is discussed whether self-organization represents an independent component of digital leadership. Addressing this research question, the instrument "DigiFuehr" is being expanded to include the aspects of self-determination and coordination. The aim is to test the model quality of three adapted scales against the already established support-focusing version.
Methods
Based on an online survey of n = 422 employees at visual display unit workstations in German municipal administrations in April 2022, the original version of DigiFuehr as well as one reduced and two extended versions were validated considering their local and global model fit.
Results
All four scales show a good local fit with regard to internal consistency (Cronbach's α), discriminatory power and dimensionality. Only the scale extended by two items also offers a sufficient global fit and is thus most suitable as a predictor for psychological stress, work satisfaction and satisfaction with the professional exchange during homeworking.
Conclusions
With "DigiFuehr 2.0", an improved version of the original scale is available. Self-organization is not a component independent of the support dimension, but a further important indicator of a latent digital leadership culture. Neither should come at the expense of the other.

Purpose Patient follow-up is an essential part of hospital management. With the advent of the information age, patient follow-up is expected to be replaced by Internet technology. This study constructed a gynecological chemotherapy patient cloud follow-up platform to evaluate its cost-effectiveness and patient feedback effect.Methods A total of 2538 patients were followed up using a cloud follow-up system between January and October 2021. Prior to this, 690 patients were followed up manually over telephonic calls. The patient characteristics, follow-up rate, patient satisfaction, and session duration in the cloud follow-up group and manual follow-up group were compared. In addition, the read rate of health education materials in the cloud follow-up group was analyzed.Results The general information (age, cancer stage, and disease category) and follow-up rate (cloud: 6957/7614, 91.4%; manual: 1869/2070, 90.3%; P=0.13) did not significantly differ between the two groups. The follow-up satisfaction of the cloud follow-up patients was significantly better than that of the manual follow-up group (cloud: 7192/7614, 94.5%; manual: 1532/2070, 74.0%; P＜0.001). The time spent on the follow-up of 100 patients in the cloud follow-up group was approximately 1.2 hours compared to 10.5 hours in the manual follow-up group. The read rate of health education materials in the cloud follow-up group was 72.9%.Conclusions The follow-up effect of the cloud follow-up group was not inferior to that of the manual follow-up group, and the cloud follow-up group was more in line with the prevention and control requirements of the post-epidemic era. Cloud follow-up can save medical resources, improve cost-effectiveness, provide sufficient health education resources for patients, and improve patient satisfaction.

BACKGROUND: Lip-splitting approach for oncologic resection and defect reconstruction of tongue squamous cell carcinoma (TSCC) needs modification to avoid unfavorable aesthetic results. METHODS: Forty-three patients with TSCC underwent surgery using the modified submandibular mandibulotomy( MSMM) approach without lip-splitting and another matched 43 patients using lip-splitting mandibulotomy (LSM) approach were reviewed retrospectively. Clinical outcomes evaluation consisted of tumor exposure, resection margin, surgical morbidity, locoregional recurrence, survival status, scar scores and quality of life (QOL). RESULTS: All the tumors were en bolc removed by MSMM approach and LSM approach through combined intraoral routes with excellent tumor exposure and R0 resection margins. Tumor recurrence rates and swallowing, chewing, speech were similar in both groups. The MSMM approach was associated with significantly better facial appearance and recreation than LSM approach. CONCLUSION: The MSMM approach without lip-splitting is safe and effective, achieves better aesthetic results and QOL compared to LSM approach in patients with TSCC.

Metasurfaces have recently realised many revolutionary applications such as metalenses, equation solvers, beam shapers, and holographic projection.1–4 However, the conventional metasurfaces are monotask due to their fixed dimensions. Therefore, realising multitask metasurfaces for applications such as beam steering, optical switches and meta-displays, which require fast and dynamic reconfigurability, has bottlenecked. To address this technological challenge, there has been a quest to enable tunability via mechanical tilting or stretching the samples, rotating the illumination angle or the incident light polarisation, use of chemical reactions, and others.5–8 However, most of these approaches still suffer from slow tuning rate, weak modulation, and bulky or non-solid state components. Here, we introduce electrically tunable metasurfaces that offer up to 9 folds surge in transmission, i.e. 90% transmission modulation depth, with switching time <625 µs, i.e. one order of magnitude faster than video frame rates. To realise such a breakthrough, we have driven the designed metasurface by <5 V spiked voltage, asymmetrically, for the first time in optoelectronics.

The Brazilian scientific community has available a curricular information system called Lattes. The analysis in the area of scientific production is rapidly evolving as we have an increase in the number of publications combined with increasingly interdisciplinary sources of information. The Brazilian scientific community has available a database with curricular information called Lattes which contain information about academic and scientific achievements. There is a demand to carry out the search and retrieval of information from the Lattes curriculum in order to reduce the difficulties in exploring bibliometric data and to aid in the analysis of this information. This article uses textual data mining techniques, multidimensional projection techniques and visualization based on analysis of bibliometric data extracted from the Lattes platform. The results obtained were clusters of research groups that are related to each other and clusters of research groups that work with very different themes. These results can become a tool for visually exploring bibliometric data from the Lattes platform.

Published: May 2022

BackgroundChest wall sinus with infection is a refractory disease caused by a variety of susceptible factors, and the treatment is still challenging.For clinically complex cases, although there are various surgical methods to choose from, it is still very difficult to achieve clinical cure,especially for patients with older age and many underlying diseases.Complete resection of chest wall sinus and application of repair and reconstruction technology may bring hope to refractory cases.Case presentationHerein,We report a case of a 67-year-old woman who had undergone breast cancer surgery and a history of multiple cycles of radiotherapy and chemotherapy.One year ago, she had a fistula in the left chest wall with yellow purulent fluid.After admission to our hospital, chest computed tomography (CT) showed the formation of the left chest wall sinus, accompanied by high-density images of the left clavicle, part of the ribs and part of the sternu.According to the patient's symptoms, signs and imaging examination, we preliminarily diagnosed the patient as chest wall sinus with infection and chronic osteomyelitis.Therefore, in the first-stage operation,the patient underwent left chest wall sinus resection, left partial rib resection, left partial clavicular resection and left partial sternal resection,After surgery, the wound surface was changed with gauze dressing with sensitive antibiotic solution every day until the wound surface was clean and new granulation was formed.In the second-stage operation, the wound surface was appropriately expanded, and the pedicled latissimus dorsi myocutaneous flap was transferred to the chest wall defect. Finally, the skin paddle was sutured without tension to the normal skin around the chest, and two drainage tubes were placed.Anti-infection, anti-spasm, anti-coagulation and other treatments were given after operation, and the survival of myocutaneous flap, wound healing and sinus disappearance were observed.ConclusionsThe application of pedicled latissimus dorsi myocutaneous flap in the treatment of intractable chronic chest wall sinus is an effective method. It does not change the shape of the thorax. The clinical effect is satisfactory in the near and medium term, which is worthy of clinical promotion.
