Published: December 2022

Objective: Experience of the conventional and a de novo Mitral repair techniques for the treatment of Severe Mitral Regurgitation (MR) in a Tertiary Care Cardiac Hospital of Pakistan.

Study Design: Descriptive cross sectional

Place and Duration of Study: Cardiac Surgical Division, Armed Forces Institute of Cardiology and National Institute of Heart Diseases, Rawalpindi, Pakistan

Methodology: This was a cross sectional study conducted over a period of 5 years from 2016 to 2020, which included SeventyFive (n=75) patients in the trial, 55 females and 20 males. The mean age was 23±9.5 years (range from 16 to 52 years). Amongst all cases of mitral regurgitation (MR) were five (6%) myxomatous degenerative changes, three (4%) ischemic MR & Sixtyseven (91%) patients had rheumatic aetiology. Five (05) patients with myxomatous diseases required only ring annuloplasty. In patients with ischemic MR, two required chordal shortening for anterior leaflet resuspension, and one required quadrangular resection of the posterior leaflet. Restrictive annuloplasty±Coronary Artery Bypass Grafting (CABG) was alsoperformed as part of the procedures. Sixty-seven (91%) patients having severe Mitral Regurgitation with rheumatic aetiology, required a myriad of procedures; including neo-chordae suspension for anterior & posterior mitral leaflets, quadrangular resection & reattachment of the posterior mitral leaflet. A novel innovative procedure, “Posterior annulus-sliding-plasty” (Nasir’s Technique) was adopted in patients with relatively fixed posterior mitral leaflet. Semi-rigid rings (Carbomedics® or Medtronic CG future®) were used in all the patients to stabilize our repair.

Results: There was no operative mortality. Patients were followed up for 01-year. Most of the patients have been found to have adequate intact Mitral Valve Repair. Only 01 patient developed Grade-II MR after 06 months (ischemic aetiology). This patient is being followed up at 06 monthly intervals with transthoracic echo and is being treated as per guideline-directed medical therapy (GMDT) for functional MR.

Conclusion: Mitral Valve Repair in the carefully selected subset of patients with severe MR, irrespective of aetiology can effectively be treated with satisfactory short-term and medium-term results.

Objective: To study the relationship of body mass index (BMI) and postoperative bleeding in patients undergoing isolated coronary artery bypass grafting (CABG) using cardiopulmonary bypass (CPB).

Study Design: Analytical cross sectional study

Place and Duration of Study: Cardiothoracic services, Almana General Hospital, Al Khobar, Saudi Arabia, from Oct 2019 to Oct 2021.

Methodology: Two hundred and twenty (220) consecutive patients who underwent CABG using cardiopulmonary bypass were included in the study. Patients who had additional procedures, those who were operated in emergency and those with significant comorbidities like hepatic and liver dysfunction were excluded from the final analysis. Patients were divided into three groups according to their BMI, healthy weight (BMI 18.5 to <25), overweight (BMI 25 to <30) and obese (BMI >30). The world health organization (WHO) definition was used to define different categories of BMI. Various perioperative variables were recorded for all the patients. Only the immediate postoperative follow up period was included in the study. Data was analyzed using IBM SPSS-statistics 23.0 (IBM, SPSS Inc., Chicago, IL).

Results: Of the 220 patients included in the study, 184(83%) were male patients and 36(16%) female patients. There was no significant difference in the mean age of the patients in the three groups (p=0.481). There were significantly more hypertensive patients 46(45%) in the overweight group compared to other two groups (p=0.025). Baseline diabetic status was not significantly different among the three categories (p=0.978). Total mediastinal drainage in the first 24 hours was significantly less in the obese group (3.7±4.45 ml) compared to overweight (4.4±2.7 ml) and healthy weight (7.35±8.5 ml) patients (p=0.001). There was no mortality in the studied cohort.

Conclusion: Bleeding after isolated coronary artery bypass grafting is inversely related to BMI. Patients with healthy and overweight BMI are at higher risk of bleeding compared to obese patients.

Cardioversion in Infantile Atrial Flutter
Authors: Ara Andaleeb , Akhtar Khurram , Rafique Saima , Farhan Mohammad Asad , Ahmed Tufail
Published: December 2022

Atrial flutter (AFL) is a rare arrhythmia in neonatal and infantile period. Potentially, AFL might lead to severe morbidity and even a fatal outcome. However it can have a good prognosis with early diagnosis and prompt appropriate treatment. Synchronized electrical cardioversion or transoesophageal atrial overdrive pacing is recommended in both stable and unstable cases. Antiarrhythmic drugs can be tried in stable newborns though the sinus rhythm takes some time to return to normal.Excellent prognosis has been noted in newborns and infants having AFL after sinus rhythm has been restored. The risk of recurrence is low and prolonged antiarrhythmic therapy is less likely to be required. However follow-up after discharge is essential to look for any possibility of recurrent arrhythmia and possible untoward effects of treatment.

Published: December 2022

Critical congenital pulmonary stenosis with intact interventricular septum is a cyanotic and potentially lethal neonatal cardiac anomaly. Percutaneous transcatheter balloon pulmonary valvuloplasty for critical pulmonary stenosis often presents technical difficulties due to supra-systemic pressure in right ventricle. Using transjugular approach instead of the femoral vein helps in dealing with this issue. We describe the successful use of right internal jugular vein approach in a case of critical pulmonary stenosis.

Desvendando Matraga e Saturnino: um olhar comparativo das obras de Guimarães Rosa e Luiz Marinho
Authors: Santos Amanda Lins Seabra Marques dos
Published: December 2022

Guimarães Rosa e Luiz Marinho, atentos a um período histórico do Brasil, traduziram em suas obras literárias A hora e a vez de Augusto Matraga e A derradeira ceia, respectivamente, questões sociais, políticas e até existenciais com muita sensibilidade. Essas duas obras, contudo, trazem surpreendentes coincidências, apesar de estarem localizadas em “sertões” diferentes. Ambas ressaltam o drama da sobrevivência em regiões onde a lei é a do mais forte ou poderoso, mas também trazem a misticidade que se confunde com a religiosidade e a cultura que faz aflorar o homem, qualquer homem, que é luz e escuridão ao mesmo tempo.

Published: December 2022

Background: Rapid antimicrobial susceptibility testing (RAST) is important for the appropriate treatment of bloodstream infections. The QMAC-dRAST system (QuantaMatrix Inc., Korea) can directly perform RAST using positive blood culture samples with microscopic imaging. This study aimed to evaluate the performance of the QMAC-dRAST system for AmpC β-lactamase-producing Enterobacterales. Methods: Eighty isolates (20 Morganella morganii, 20 Serratia marcescens, 10 Klebsiella aerogenes, 10 Enterobacter cloacae, and 20 Citrobacter freundii) and 14 antimicrobial agents were included in the antimicrobial susceptibility testing (AST). The performance of the QMAC-dRAST system was evaluated by simulating the clinical blood culturing process. We conducted a comparative evaluation of the QMAC-dRAST and Vitek 2 systems (bioMérieux Inc., France). Broth microdilution tests were performed as the reference method to resolve any discrepancies in the AST results between the two systems. Results: For 20 M. morganii and 20 S. marcescens, the categorical agreement (CA) between the QMAC-dRAST and Vitek 2 systems increased from 55.4% to 83.8% after AST algorithm optimization. Moreover, the discrepancy rates decreased as follows: from 19.1% to 5.4% very major errors (VME), from 38.3% to 4.3% major errors (ME), and from 14.6% to 12.1% minor errors (mE) for the QMAC-dRAST system compared to the Vitek 2 system. For all 80 tested isolates, the QMAC-dRAST system showed 93.0% CA, 1.7% VME, 2.3% ME, and 4.9% mE. Conclusion: The QMAC-dRAST system was comparable to the Vitek 2 system after AST algorithm optimization for AmpC β-lactamase-producers, which are major pathogens and require time to express the enzyme. However, further modifications of the AST algorithm are still warranted.

Published: December 2022

Background: We compared the antimicrobial resistance rates (AMRs) of major glucose nonfermenting gram-negative bacilli, Acinetobacter baumannii and Pseudomonas aeruginosa, under different clinical conditions. The purpose of the study was to provide useful background data to set up infection control strategies for infection-vulnerable patients. Methods: The AMRs of blood isolates were compared in various clinical conditions, using data from the Antimicrobial Resistance Surveillance System in Korea. Results: A. baumannii blood isolates from patients with healthcare-associated infections, inpatients, or intensive care unit (ICU)-admitted patients consistently exhibited higher AMRs to most antimicrobials, except minocycline, tigecycline, and colistin, compared with those from patients with community-acquired infections, outpatients, or non-ICU-admitted patients, respectively. P. aeruginosa blood isolates from patients with healthcare-associated infections showed higher AMRs to most antimicrobials, except ceftazidime and aztreonam, compared with those from patients with community-acquired infections, but not compared to those from inpatients or ICU-admitted patients. Conclusion: Higher AMRs were associated with A. baumannii bloodstream infections under various clinical conditions, such as healthcare-associated infections and infections in inpatients and ICU-admitted patients. Considering the high AMRs and the limited number of treatment options of A. baumannii, vigorous efforts should be used to prevent the spreading of A. baumannii infections in patients with vulnerable conditions.

Dominantlık durumunun genetik ve çevresel faktörler arasındaki çok yönlü etkileşimle ortaya çıktığı düşünülmektedir. Motor öğrenme ise hareket yeteneğinde tecrübe veya pratikle oluşan kalıcı değişimleri içeren bir süreci ifade eder. Bu çalışmanın amacı sağlıklı gençlerde el göz ve ayak dominantlığı ile motor öğrenme becerisi arasındaki ilişkinin incelenmesidir. Araştırmaya 107 sağlıklı genç birey dahil edildi. Ayrıca veri toplamak için “Edinburg El Tercih Anketi”, “Yenilenmiş Waterloo Ayak Tercihi Anketi”, “Miles ve Ports Lateralizasyon Testi” ve “İz Sürme Testi” kullanıldı. Dominant olan gözlerin karşılaştırılması Mann-Whitney U testi kullanılarak; dominant olan el ve ayakların karşılaştırılması Kruskal-Wallis H testi kullanılarak incelendi. Dominant olan el, göz ve ayaklar arasındaki ilişkiyi belirlemek amacıyla logaritmik doğrusal model uygulanarak; ana etkiler ve ikili etkileşimlerin önemli olduğu (p<0.001; p<0.01), üçlü etkileşimin önemli olmadığı belirlendi (p=0.993). Dominant olan el, ayak ve gözler arasında İz Sürme Testinin skorları açısından fark olmadığı belirlendi (p>0.05). Yapılan çalışma sonucunda sağlıklı gençlerde el, göz ve ayak dominantlığı ile motor öğrenme becerisi arasında ilişki olmadığı belirlendi. Bununla birlikte el dominantlığı ile ayak dominantlığı arasında ve göz dominantlığı ile ayak dominantlığı arasında ilişki olduğu; el dominantlığı ile göz dominantlığı arasında ilişki olmadığı belirlendi. Çalışmanın sonuçları el, ayak ve göz dominatlık durumunun motor öğrenmeyi etkilemediğini desteklemektedir.

Authors: Fang Xin , Li Feng , Sun Lei-lei , Li Tao
Published: December 2022

Abstract. We report the first Pseudo-random Modulation Continuous Wave (PMCW) narrowband sodium temperature/wind lidar developed at the University of Science and Technology of China (USTC). The laser system uses an 1178 nm diode seed-laser and a fiber Raman amplifier with a fiber-coupled Acoustic Optical Modulator (AOM) to generate a narrowband 589.158 nm light with a power output of 1.5 W at v0, v+ and v_ frequencies. Based on an innovative technique and algorithm, the main beam and the residual beam modulated by Electro-Optic Modulator (EOM) with M-code are separately directed to the vertical and eastward directions. The 3-frequency light is designed in timing with the multiple-period 127-bit M-code groups. The uncertainties of the temperature and wind with the vertical and temporal resolutions of 1 km and 30 min/1 hr under the clear-sky condition are estimated to be 5.0 K and 10 m/s, respectively at the sodium peak. The temperature and wind results are in good agreement with those observed by satellite and nearby ground-based meteor radar, demonstrating the reliability of the PMCW narrowband sodium lidar system for measuring mesopause region temperature and wind.
Assessment of S2S ensemble extreme precipitation forecasts over Europe
Authors: Rivoire Pauline , Martius Olivia , Naveau Philippe , Tuel Alexandre
Published: December 2022

Abstract. Heavy precipitation can lead to floods and landslides, resulting in widespread damage and significant casualties. Some of its impacts can be mitigated if reliable forecasts and warnings are available. Of particular interest is the subseasonal to seasonal (S2S) prediction timescale. The S2S prediction timescale has received increasing attention in the research community because of its importance for many sectors. However, very few forecast skill assessments of precipitation extremes in S2S forecast data have been conducted. The goal of this article is to introduce a new methodology to assess the skill of rare events, here extreme precipitation, in S2S forecasts. We verify extreme precipitation events over Europe in the S2S forecast model from the European Centre for Medium-Range Weather Forecasts. The verification is conducted against ERA5 reanalysis precipitation. Extreme precipitation is defined as daily precipitation accumulations exceeding the seasonal 95th percentile. In addition to the classical Brier score, we use a binary loss index to assess skill. The binary loss index is tailored to assess the skill of rare events. We analyse daily events locally and spatially aggregated, as well as 7-day extreme event counts. Results consistently show a higher skill in winter compared to summer. The regions showing the highest skill are Norway, Portugal and the south of the Alps. Skill increases when aggregating the extremes spatially or temporally. The verification methodology can be adapted and applied to other variables, e.g. temperature extremes or river discharge.
Elucidating ozone and PM2.5 pollution in Fenwei Plain reveals the co-benefits of controlling precursor gas emissions in winter haze

Published: December 2022

Abstract. Fenwei Plain, home to 50 million people in central China, is one of the most polluted regions in China. In 2018, Fenwei Plain is designated as one of the three key regions for the “Blue Sky Protection Campaign”, along with the Beijing-Tianjin-Hebei (BTH) and Yangtze River Delta (YRD) regions. However, compared to BTH and YRD, our understanding of the current status of air pollution in the Fenwei Plain is limited partly due to a lack of detailed analysis of the transformation from precursor gases to secondary products including secondary organic aerosol (SOA) and ozone. Through the analysis of 7 years (2015–2021) of surface monitoring of the air pollutants in Xi’an, the largest city in the Fenwei Plain, we show that roughly 2/3 of the days exceeded either the PM2.5 or the O3 level-1 air quality standard, highlighting the severity of air pollution. Moreover, an increase in O3 pollution in the winter haze was also revealed, due to the constantly elevated reactive oxygenated volatile organic compounds (OVOCs), and in particular formaldehyde with ozone formation potential of over 50 μg m−3 in combination with the reduced NO2. The abrupt decrease of NO2, as observed during the lockdown in 2020, provided real-world evidence of the control measures, targeting only NOx (70 % decrease on average), were insufficient to reduce ozone pollution because reactive OVOCs remained constantly high in a VOC-limited regime. Model simulation results showed that with NO2 reduction from 20–70 %, the self-reaction rate between peroxy radicals, a pathway for SOA formation, was intensified by up to 75 %, while the self-reaction rate was only reduced with a further reduction of VOCs of > 50 %. Therefore, a synergic reduction in PM2.5 and O3 pollution can only be achieved through a more aggressive reduction of their precursor gases. This study elucidates the status of ozone and PM2.5 pollution in one of the most polluted regions in China, revealing a general trend of increasing secondary pollution i.e., ozone and SOA in winter haze. Controlling precursor gas emissions is anticipated to curb both ozone and SOA formation which will benefit not just the Fenwei Plain but also other regions in China.

Published: December 2022

Abstract. Surface ozone is an important air pollutant detrimental to human health and vegetation productivity. Regardless of its short atmospheric lifetime, surface ozone has significantly increased since the 1970s across the Northern Hemisphere, particularly in China. However, high temporal resolution surface ozone concentration data is still lacking in China, largely hindering accurate assessment of associated environmental and human health impacts. Here, we collected hourly ground ozone observations (over 6 million records), meteorological data, remote sensing products, and social-economic information, and applied the Long Short-Term Memory (LSTM) recurrent neural networks to map hourly surface ozone data (HrSOD) at a 0.1° × 0.1° resolution across China during 2005–2020. Benefiting from its advantage in time-series prediction, the LSTM model well captured the spatiotemporal dynamics of observed ozone concentrations, with the sample-based, site-based, and by-year cross-validation coefficient of determination (R2) values being 0.72, 0.65 and 0.71, and root mean square error (RMSE) values being 11.71 ppb (mean = 30.89 ppb), 12.81 ppb (mean = 30.96 ppb) and 11.14 ppb (mean = 31.26 ppb), respectively. Air temperature, atmospheric pressure, and relative humidity were found to be the primary influencing factors. Spatially, surface ozone concentrations were high in northwestern China and low in the Sichuan Basin and northeastern China. Among the four megacity clusters in China, namely the Beijing-Tianjin-Hebei region, the Pearl River Delta, the Yangtze River Delta, and the Sichuan Basin, surface ozone concentration kept decreasing before 2016. However, it tended to increase thereafter in the former three regions, though an abrupt decrease in surface ozone concentrations occurred in 2020. Overall, the HrSOD provides critical information for surface ozone pollution dynamics in China and can support fine-resolution environmental impact and human health risk assessment. The data set is available at https://doi.org/10.5281/zenodo.7415326 (Zhang et al., 2022).
Improving scalability of Earth system models through coarse-grained component concurrency – a case study with the ICON v2.6.5 modelling system
Authors: Linardakis Leonidas , Stemmler Irene , Hanke Moritz , Ramme Lennart , Chegini Fatemeh , Ilyina Tatiana , Korn Peter
Published: December 2022

Abstract. In the era of exascale computing, machines with unprecedented computing power are available.
Making efficient use of these massively parallel machines, with millions of cores, presents a new challenge.
Multi-level and multi-dimensional parallelism will be needed to meet this challenge. Coarse-grained component concurrency provides an additional parallelism dimension
that complements typically used parallelization methods such as domain decomposition and
loop-level shared-memory approaches.
While these parallelization methods are data-parallel techniques, and they decompose the data space, component concurrency is a function-parallel technique, and it decomposes the algorithmic space.
This additional dimension of parallelism allows us to extend scalability beyond the limits set by established parallelization techniques.
It also offers a way to maintain performance (by using more compute power)
when the model complexity is increased by adding components, such as biogeochemistry or ice sheet models.
Furthermore, concurrency allows each component to run on different hardware,
thus leveraging the usage of heterogeneous hardware configurations. In this work we study the characteristics of component concurrency and analyse its behaviour in a general context.
The analysis shows that component concurrency increases the “parallel workload”,
improving the scalability under certain conditions.
These generic considerations are complemented by an analysis of a specific case, namely the coarse-grained concurrency in the multi-level parallelism context of two components of the ICON modelling system: the ICON ocean model ICON-O and the marine biogeochemistry model HAMOCC.
The additional computational cost incurred
by the biogeochemistry module is about 3 times that of the ICON-O ocean stand alone model,
and data parallelization techniques (domain decomposition and loop-level shared-memory parallelization)
present a scaling limit that impedes the computational performance of the combined ICON-O–HAMOCC model.
Scaling experiments, with and without concurrency,
show that component concurrency extends the scaling, in cases doubling the parallel efficiency.
The experiments' scaling results are in agreement with the theoretical analysis.

Abstract. Purpose: The purpose of this study was the clinical and therapeutic assessment of lower-limb
osteosynthesis-associated infection (OAI) by multidrug-resistant (MDR) and
extensively drug-resistant (XDR) Gram-negative bacteria (GNB), which have been
poorly studied to date.
Methods: A prospective multicentre observational study was conducted on
behalf of ESGIAI (the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) Study Group on Implant-Associated Infections).
Factors associated with remission of the infection were evaluated by
multivariate and Cox regression analysis for a 24-month follow-up period.
Results: Patients (n=57) had a history of trauma (87.7 %), tumour
resection (7 %) and other bone lesions (5.3 %). Pathogens included Escherichia coli
(n=16), Pseudomonas aeruginosa (n=14; XDR 50 %), Klebsiella spp. (n=7), Enterobacter spp. (n=9), Acinetobacter spp. (n=5),
Proteus mirabilis (n=3), Serratia marcescens (n=2) and Stenotrophomonas maltophilia (n=1). The prevalence of ESBL (extended-spectrum β-lactamase), fluoroquinolone and
carbapenem resistance were 71.9 %, 59.6 % and 17.5 % respectively.
Most patients (n=37; 64.9 %) were treated with a combination including
carbapenems (n=32) and colistin (n=11) for a mean of 63.3 d. Implant
retention with debridement occurred in early OAI (66.7 %), whereas the
infected device was removed in late OAI (70.4 %) (p=0.008). OAI remission
was achieved in 29 cases (50.9 %). The type of surgery, antimicrobial
resistance and duration of treatment did not significantly influence the
outcome. Independent predictors of the failure to eradicate OAI were
age >60 years (hazard ratio, HR, of 3.875; 95 % confidence interval, CI95 %, of 1.540–9.752; p=0.004) and
multiple surgeries for OAI (HR of 2.822; CI95 % of 1.144–6.963; p=0.024).
Conclusions: Only half of the MDR/XDR GNB OAI cases treated by antimicrobials and
surgery had a successful outcome. Advanced age and multiple surgeries
hampered the eradication of OAI. Optimal therapeutic options remain a challenge.
Damping analysis of Floating Offshore Wind Turbine (FOWT): a new control strategy reducing the platform vibrations
Authors: Capaldo Matteo , Mella Paul
Published: December 2022

Abstract. In this paper, the coupled dynamics of the floating platform and the wind turbine rotor is analysed. In particular, the damping is explicitly derived from the coupled equations of rotor and floating platform. The analysis of the damping leads to the study of the instability phenomena obtaining the explicit conditions that lead to the Non Minimum Phase Zero (NMPZ). Two NMPZs are analysed, one related to the rotor dynamics and the other one to the platform pitch dynamics. The latter is a novelty and an explicit condition is introduced in this work for its verification. In the second part of the paper, from the analysis of the damping of the floating platform, a new strategy for the control of Floating Offshore Wind Turbines (FOWTs) is proposed. This strategy allows one to impose to the controller an explicit level of damping in the platform pitch motion without changing the period of platform pitching. Finally the new strategy is compared to the one without compensation by performing aero-hydro-servo-elastic numerical simulations of a reference FOWT. Generated power, movements, blade pitch and tower base fatigue are compared showing that the new control strategy can reduce fatigue in the structure without affecting the power production.
Otrokove koristi – pravica ali zgolj načelo Listine EU o temeljnih pravicah?
Authors: Samobor Ana
Published: December 2022

Listina EU o temeljnih pravicah v prvem odstavku 51. člena in petem odstavku 52. člena uvaja razlikovanje med pravicami in načeli. Čeprav je bilo to razlikovanje eno pomembnejših vprašanj v procesu snovanja njenega besedila, iz Listine ni mogoče razbrati niti tega, katere izmed določb so načela in katere pravice, niti pravnih posledic take razmejitve. Oblikovanje meril in klasifikacija posameznih določb je torej v rokah Sodišča EU, vendar sodna praksa (še) ne ponuja jasnih zaključkov. Ena od določb, katerih pravna narava ostaja nejasna, je tudi drugi odstavek 24. člena Listine, ki določa, naj se pri vseh ukrepih, ki se nanašajo na otroke, upoštevajo predvsem njihove koristi. Avtorica se v prispevku na podlagi razmeroma skope sodne prakse ter relevantne literature opredeljuje do pravne narave navedene določbe ter pravnih posledic njene klasifikacije.
A utilização de incentivos fiscais, em Nova Serrana, direcionada às entidades filantrópicas por meio do imposto de renda de pessoas físicas

Published: December 2022

As entidades sem fins lucrativos têm como principal objetivo prestar serviços públicos à sociedade, de forma a amenizar o desequilíbrio social. Diante disso, uma forma de custear essas entidades é a utilização de incentivos fiscais, por meio do repasse do Imposto de Renda, em que o governo federal renuncia parte do imposto arrecadado e o repassa para entidades sem fins lucrativos e de cunho social. Isso, para que a população possa apoiar e ajudar projetos sociais dentro da sociedade em que está inserida. Portanto o presente estudo se propõe a verificar o nível de conhecimento dos contribuintes sobre a utilização de incentivos fiscais por meio do Imposto de Renda de Pessoa Física optante pelo modelo de declaração completa no município de Nova Serrana. A metodologia consiste no método quantitativo com aplicação de questionário para coletar os dados junto aos contribuintes que entregam declaração de imposto de renda no modelo completo. Os dados foram organizados e tabulados por meio da ferramenta Google Planilhas, para que fosse possível comparar as respostas dos participantes, analisando-as como propõem a pesquisa. Os resultados alcançados mostraram que a maior parte dos contribuintes não tem conhecimento sobre esse assunto, que o contador que estabelece o contato com o contribuinte é o menor divulgador dessa informação.
“Loading memories…”: Deteriorating pasts and distant futures in Stuart Campbell’s These Memories Won’t Last
Authors: Sandford Shannon
Published: December 2022

The field of comics has undergone palpable shifts in print and digital publishing cultures, from newspaper strips and zines to hardbound graphic novels and works still emerging in the era of Web 2.0. Comics that leave behind the aesthetic trappings of print to embrace digital platforms and media are known variously as digital comics, download comics, hypercomics and webcomics. This paper adopts the term “webcomics” to denote a precise, hybrid medium combining the visual-verbal grammar of comics with the capacious potentials of digitality. Through the case study of These Memories Won’t Last, a webcomic by Australian artist and graphic designer Stuart Campbell (known by his pseudonym, Sutu), I aim to explore the ways Campbell engages sound, animation and other interactive elements alongside drawings that render the lived experiences of his grandfather, who suffers from late-stage dementia. This paper considers how webcomics might transform the stasis of word-and-image to explore and communicate subjects that sit on the outer edges of representation, such as memory, identity and trauma. It responds to a new generation of artists who harness digital technologies to expand and revise the comics form and considers the potential effects of this practice on creating, reading and interpretating life stories.
La Realidad Virtual como herramienta en la comunicación de desastres naturales: el caso de RTVC y su representación de la erupción del volcán de la Palma
Authors: Sánchez Calero María Luisa , Triguero Oliveros Beatriz
Published: December 2022

Este trabajo analiza el uso y la utilidad de la Realidad Virtual (RV) en la cobertura de desastres naturales tomando como objeto de análisis el caso concreto del volcán de Cumbre Vieja, en La Palma. Un desastre natural que provocó una situación de emergencia tras entrar en erupción el 19 de septiembre de 2021, prolongándose durante 85 días. Esta investigación pretende conocer el tratamiento y difusión que le dispensó el programa ‘Una Hora Menos’ de la Radio Televisión Canaria (RTVC), emitido de lunes a viernes a las 21.30 horas. Se analizará también la repercusión social que generó el uso de la RV en la representación de la comunicación del desastre y qué percepción tuvo la opinión pública a través de los mensajes emitidos en la red social de Twitter.
La representación de la Unión Europea en los medios de comunicación españoles: temas y actores dominantes sobre el proceso de europeización
Authors: García-Carretero Lucía , Establés María-Josefa , Pérez-Escoda Ana , Boulos Sonia
Published: December 2022

Los acontecimientos globales ocurridos en los dos últimos años han dibujado un escenario intenso desde el punto de vista informativo, institucional y político. Los medios de comunicación se han legitimado ante la infodemia causada por la Covid-19 y la Guerra de Ucrania estableciendo una agenda-setting específica en la representación de la Unión Europea. En este contexto, presentamos una investigación que tiene como principal objetivo analizar la mediatización de los discursos sobre la UE en los medios españoles. Con una metodología de análisis de contenido cualitativo se han analizado un total de 543 noticias publicadas y/o emitidas en seis medios de comunicación españoles (El País, El Confidencial, ABC, El Diario.es, TVE y Antena 3) en un periodo temporal de nueve meses. La codificación y análisis de las fuentes estudiadas dio como resultado la detección de los tópicos y actores más destacados en el discurso de los medios respecto a la cuestión de la europeización.
La esfera pública en la encrucijada: fragmentación, crisis del periodismo y desinformación
Authors: Iranzo-Cabrera María , Calvo Dafne , Valera-Ordaz Lidia
Published: December 2022

En la esfera pública contemporánea la verdad es impugnada no solo desde las nuevas plataformas de comunicación digitales, sino también desde instituciones como la política o el periodismo convencional. La adquisición de conocimiento para la toma de decisiones ciudadanas se ve cuestionada por la creciente polarización política, la fragmentación mediática, el absolutismo moral y las dudas suscitadas por la verificación de datos que ejercen nuevos agentes comunicativos. Si bien la libertad de expresión ha sido el derecho exigido en el debate público y los medios alternativos se muestran útiles para elevar contradiscursos contra las élites, las falsedades intencionadas y los discursos de odio que circulan de forma masiva en el actual sistema híbrido de comunicación ponen seriamente en peligro bienes de titularidad pública, como la salud y los procesos electorales.
Una revisión sistemática de literatura: memoria colectiva, infancia y migración
Authors: Hedrera Manara Luciana , Mazzucchelli Nicole , Íñiguez-Rueda Lupicinio
Published: December 2022

Infancia, memoria colectiva y migración, suelen ser temáticas que la literatura científica aborda por separado. En el presente artículo, exponemos los resultados de una revisión sistemática que tuvo como propósito identificar la producción científica en torno a la memoria social, la infancia y la migración entre los años 2010-2020 en formato de artículos científicos. Siguiendo las directrices PRISMA, incluimos 38 artículos científicos mediante un análisis temático. Los resultados dan cuenta de la construcción de memoria de los/as niños/as desde aspectos identitarios; a través de la transmisión intergeneracional y la posmemoria, y por medio de experiencias de migraciones transnacionales y forzadas. Por último, algunas investigaciones se preocupan de estudiar las memorias como prácticas de resistencia, y a los/as niños/as como agentes de la memoria colectiva. Finalmente, por medio de las discusiones y las conclusiones, reflexionamos sobre las maneras en que se conciben a los/as niños/as en estos campos de estudio y la importancia de valorar su participación en investigaciones que tratan sobre las prácticas de memoria y los procesos migratorios, junto a algunas limitaciones y contribuciones de la revisión.
Desvios do espetáculo autobiográfico Revele!
Authors: Sanches João
Published: December 2022

O artigo discute as principais estratégias de desvio do espetáculo autobiográfico Revele!, encenado em Salvador nos anos de 2018 e 2019. A perspectiva teórica do trabalho baseia-se nas noções de crise do drama e desvio, formuladas respectivamente por Peter Szondi e por Jean-Pierre Sarrazac, em articulação com noções ampliadas de dramaturgia como as propostas pelos teóricos José Sanchez e Joseph Danan. O estudo ainda dialoga com o trabalho de outros artistas e teóricos como Fernando Kinas, Patrice Pavis e Erika Fischer-Lichte. O texto apresenta uma análise dos principais aspectos da referida montagem baiana que se diferenciam de poéticas tradicionais, ou de concepções estéticas majoritárias, e que são recorrentes no teatro contemporâneo, particularmente nas formas cênicas conhecidas como peça-conferência, ou conferência-espetáculo. Os desvios identificados no estudo indicam como principais estratégias dessas formas a enunciação direta para a plateia, o discurso monodramático e as tentativas de emersão do real em cena.
New data on the genus Cornus L. (Cornaceae) in the Bulgarian Miocene flora
Authors: Bozukov Vladimir , Hristova Latinka , Ranguelov Boyko
Published: December 2022

New data on the distribution of species of the genus Cornus on the territory of Bulgaria during the Miocene are presented. The species C. megaphylla was found for the first time in the middle Miocene flora from Satovcha (SW Bulgaria). So far, this species has been established in the middle Miocene flora from Ruzhintsi (NW Bulgaria). A revision of the species C. distans from the Satovcha paleoflora as Cornus aff. alba has also been made. A new finding of a leaf imprint from the Satovcha local paleoflora proves that the fossil material has the closest morphological features to the recent species C. alba.

Authors:   Moldova State University, Strimbeanu Alexandru
Published: December 2022

The concept of „access to computerized information” refers to one of the components of the objective side of the offenses provided in art. 259 of the Criminal Code of the Republic of Moldova. The main result of the present study is the definition of this concept that generates controversies in the theory and practice of criminal law. Another notable result consists in supporting with arguments the solution to qualify the acts of: 1) maintaining illegal access to computerized information after the withdrawal or expiration of the authorization; 2) illegal intrusion into the computer, the data storage device, the computer system or the computer network, in which or on which the computerized information is located, if, due to reasons independent of the perpetrator’s will, the illegal access to that information is not committed.
