In addition to spreading information among friends, information can also be pushed through marketing accounts to non-friends. Based on these two information dissemination channels, this paper establishes a Susceptible-Infection-Marketing-Removed (SIMR) rumor propagation model. First, we obtain the basic reproduction number $ R_0 $ through the next generation matrix. Second, we prove that the solutions of the model are uniformly bounded and discuss asymptotically stable of the rumor-free equilibrium point and the rumor-prevailing equilibrium point. Third, we propose an optimal control strategy for rumors to control the spread of rumors in the network. Finally, the above theories are verified by numerical simulation methods and the necessary conclusions are drawn.

Članek analizira vložke javnih sredstev v preventivo, raziskave ter pomoč in zavarovanja na področju naravnih nesreč v Sloveniji. Predstavlja javna sredstva za preventivo, odziv in obnovo. Vlaganja v sistem zaščite in reševanja ter sredstva za zmanjšanje posledic nesreč za obdobje med 1999 (2002) in 2019 smo analizirali po podatkih proračunov. Za obdobje 1997–2011 smo ocenili vlaganja v znanost. Analizirali smo strukturo javnih sredstev za pomoč po nesrečah ter neenotnost meril med občinami. Javna sredstva smo primerjali z vlaganji zasebnikov v zavarovanja ter škodnimi izgubami in BDP-jem. Temeljna ugotovitev so obratna sorazmerja med prostorskimi enotami, kar velja za vse velikostne ravni: manjši kot je deléžnik, relativno več finančno prispeva za preventivo pred naravnimi nesrečami.

In this article we analyze the contribution of public funds for prevention, scientific research, financial aid for disaster events, and insurance in the field of natural disasters in Slovenia. It presents the public funds for prevention, response and recovery. We have analyzed the investments in the protection and rescue system and the budget for disaster mitigation for the period between 1999 (2002) and 2019. For the period 1997–2011, we estimated investments in science. We also analyzed the structure of public funds for disaster relief and the inconsistency of criteria and approaches in Slovenian municipalities. We compared public funds with private investments in insurance, with claimed losses and with GDP. The basic finding is that there is an inverse relationship between the investments of the mentioned spatial units: the smaller the actor, the greater its relative financial role in disaster management.

Authors: Wani Mudassir Maqbool , Sheikh Iqbal M , Marsh Howard , Sheriff Matin , Bhat Zubair , Mullighan John
Published: March 2022

Purpose:

The purpose of this study was to investigate the management of acute urolithiasis during index admission by primary ureteroscopy (P-URS) during coronavirus disease-2019 (COVID-19) pandemic. With the rise in prevalence of urolithiasis, the focus has shifted to manage patients presenting with acute ureteric colic during their first admission rather than using temporary measures such as emergency stenting (ES) or nephrostomies which are followed by deferred ureteroscopic procedures Deferred Ureteroscopy (D-URS). We compared the results of ES with P-URS procedures in terms of quality and cost benefits during COVID-19 pandemic.

Materials and Methods:

Data were collected prospectively from April 2020 to March 2021 for all emergency urolithiasis procedures performed including ES and P-URS. The quality assessment was based in relation to patient factors including the number of procedures per patient, number of days spent at hospital, number of days off work, and expertise of person operating. Cost analysis included theater expenses, hospital stay charges, and loss of working days.

Results:

This study revealed that the average stay of patients on index admission who had an ES was 1.35 days compared to 1.78 days in patients who underwent P-URS. Patients who had ES had to undergo D-URS and spent another average of 1.5 days in the hospital. Overall, additional expenditure in patients who did not undergo primary ureterorenoscopy was on an average in the range of £1800 (excluding loss of work for patients, who needed to return for multiple procedures).

Conclusion:

We conclude that the approach of P-URS and management of stones in index admission is very effective in both improving quality of patients (during the COVID-19 pandemic) and bringing down cost expenditure effectively.
Strong nonlinear instability and growth of Sobolev norms near quasiperiodic finite gap tori for the 2D cubic NLS equation
Authors: Guardia Marcel , Hani Zaher , Haus Emanuele , Maspero Alberto , Procesi Michela
Published: March 2022

We consider the defocusing cubic nonlinear Schrödinger equation (NLS) on the twodimensional torus. The equation admits a special family of elliptic invariant quasiperiodic tori called finite gap solutions. These are inherited from the integrable 1D model (cubic NLS on the circle) by considering solutions that depend only on one variable. We study the long-time stability of such invariant tori for the 2D NLS model and show that, under certain assumptions and over sufficiently long time scales, they exhibit a strong form of
transverse instability
in Sobolev spaces

H^s(\mathbb{T}^2)(0 < s < 1)

. More precisely, we construct solutions of the 2D cubic NLS that start arbitrarily close to such invariant tori in the

H^s

topology and whose

H^s

norm can grow by any given factor. This work is partly motivated by the problem of infinite energy cascade for 2D NLS, and seems to be the first instance where (unstable) long-time nonlinear dynamics near (linearly stable) quasiperiodic tori is studied and constructed.

Well - test analysis for wells with gas rich CO2 in carbonate reservoir Song Hong Basin
Authors: Nguyen An Hai , Nguyen Duc Hoang ,   Petrovietnam Exploration and Production Corporation, Vietnam
Published: March 2022

The evaluations of properties of carbonate reservoirs containing gas with very high carbon dioxide (CO2) content often face many difficulties. In fact, there is a significal difference in interpretation results compared to conventional gas well testing due to: there is a gas to liquid phase transition; noise, abnormal increase or decrease in pressure and temperature during flow period, etc. These abnormal behaviors are all directly related to the specificity of CO2 properties with high compressible than that of natural gas, which can vary greatly density and can reach supercritical liquid state, transitioning solid to liquid or liqid to gaseous states even when pressure and temperature changes within a small range. During the testing of gas wells with high CO2 content, the phenomenon of pressure drop while pressure buid-up often occurs, leading to the analysis of reservoir parameters according to the conventional pressure build-up analysis method usually not feasible. The content of the article is aimed at researching and applying the method of interpreting well test data in the drawdown period while multi-rate flowing to more accurately estimate reservoir properties and mitigate risks in the design of the field development plan to achieve the economic efficiency.

The paper considers the problem of keeping cars from rolling away on station railway tracks with a permissible slope of 0–2.5 ‰. The study presents the computer simulation results for the dynamic interaction of wheels with brake shoes installed on rails in the process of stopping a freight train car using standard brake shoes in the MSC.ADAMS engineering software package. In this case, various properties of the rail surface were taken into account, simulating favorable and unfavorable conditions for contact between the wheel, brake shoe and rail at braking due to both weather conditions and the peculiarities of station tracks location and operation. The interaction of the car wheels with the maximum axle load and the station brake shoes installed on the rails was studied at different initial velocities of the vehicle movement, as well as when it is at rest on tracks with the permissible slope under the conditions of ensuring the minimum friction between the wheel and the rail, as well as the interaction of rail and shoe was analyzed, which corresponds to the presence of the train on oily rails. It is demonstrated that it is not always possible for one brake shoe put on the oily rail to hold the train moving with the initial velocity more than 0.5 m/sec. Under other conditions of the wheel-brake shoe collision, the problem of keeping the train on the rails is also possible, due to such random factors as lateral wind load, rail icing, wear and deformation of the wheel surface and brake shoe, which reduce the dynamic friction coefficient between the contacting surfaces.

As time passed, numerous mathematicians gravitated towards universities. An emphasis on free thinking and trial had begun in Britain's oldest universities beginning in the seventeenth century at Oxford with the scientists Robert Hooke and Robert Boyle, and at Cambridge where Isaac Newton was Physics. Science and mathematics in the Islamic world during the Middle Periods followed colourful models and modes of backing varied grounded primarily on scholars. It was expansive patronage and strong intellectual programs enforced by specific autocrats that allowed scientific knowledge to develop in numerous areas. A mathematician is someone who uses an expansive knowledge of mathematics in their work, generally to break fine problems. Mathematicians are concerned with figures, data, volume, structure, space, models, and change.

Systemic corticosteroids are continued to be administered in juvenile idiopathic arthritis (JIA) patients, especially in systemic JIA (sJIA), despite the ability of biologic therapy. One of the complications of long-term CS treatment is delayed hip arthritis development with risk of secondary hip osteoarthritis formation and total hip arthroplasty (THA).We compared different types of hip joint lesions in JIA, especially, secondary hip osteoarthritis development and THA rates in systemic and non-systemic JIA, and evaluate systemic corticosteroids contribution to those complications.The study included 753 JIA patients. They were divided into 2 groups: patients with sJIA and non-systemic JIA (nsJIA). Clinical and demographic characteristics, CS treatment regimens were compared.Results. Hip arthritis was found equally often in both groups, but both secondary hip osteoarthritis (19% vs 5,3%) and THA (8.6% vs 1.6%) prevailed in the sJIA. Patients with sJIA had delayed hip involvement (57.9% vs 30.6%; p=0.019), earlier secondary hip osteoarthritis development (4.5 vs 5.1 years after the JIA onset) with younger age of secondary hip osteoarthritis achievement (13.7 vs 15.2 years; р=0.045), they also had higher inflammatory activity, greater systemic corticosteroids administration (94.8% vs 56.1%; р=0.0000001) and higher cumulative systemic corticosteroids dose (3085 mg vs 2000 mg; p=0,005). More than half patients (56.1%) with nsJIA had systemic corticosteroids treatment and impaired calcium-phosphorus metabolism.Conclusion. Systemic corticosteroid treatment and delayed hip involvement are independent predictors of secondary hip osteoarthritis in all JIA categories. Calcium and phosphate metabolism disturbances are additional predictor for secondary hip osteoarthritis in non-systemic JIA categories

Intra-articular injections of glucocorticoids are widely used in the complex therapy of rheumatic diseases (RD). However, there is insufficient data on their effectiveness and safety in real clinical practice.The aim of the study – to evaluate the effectiveness of intra-articular injections of glucocorticoids in rheumatic diseases in real clinical practice.Material and methods. The study group consisted of 290 patients with RD, mainly osteoarthritis (OA) and rheumatoid arthritis (RA) (69.0% – women; age – 55.6±12.6 years), who underwent intra-articular injections of glucocorticoids in the knee joint. Indications for intra-articular injections of glucocorticoids were determined by the attending physicians. The control group consisted of 112 patients with OA (71.4% – women; age 59.3±14.6 years) who underwent a course of intra-articular injections of hyaluronic acid. The result of treatment was evaluated in 2 weeks, 1 and 3 months according to a telephone survey.Result. After 2 weeks, 1 month and 3 months after the intra-articular injections of glucocorticoids, the severity of pain during movement decreased (numerical rating scale (NRS) 0–10; Me [25%; 75%]) from 6.0 [4.0; 8.0] to 1,0 [0; 2,0], 2,0 [1,0; 4,0] and 2.5 [1.0; 4.0] respectively (p<0.001). After 3 months, the number of patients with no pain or mild pain (<4 NRS) was 63.8%, with complete/almost complete absence of pain (≤1 NRS) – 30.3%. The effect of intraarticular injections of glucocorticoids was higher in RA than in OA: pain dynamics after 3 months –4.0 [–2.0; –6.0] and –2.0 [–1.0; –5.0] respectively (p=0.003). In OA, the effect of intra-articular injections of glucocorticoids and of hyaluronic acid did not differ: the dynamics of pain after 3 months was –2.0 [–1.0; –5.0] and –3.0 [–1.0; –5.0] respectively (p=0.869). No serious adverse reactions were noted at intra-articular injections of glucocorticoids.Conclusions. Intra-articular injections of glucocorticoids are an effective and fairly safe method of short-term treatment of synovitis in rheumatic diseases.

Prospects for the use of monoclonal antibodies to interleukin 23 Gusеlkumab in psoriatic arthritis: New data
Authors: Nasonov E. L. , Korotaeva T. V. , Selmi C. F.
Published: March 2022

Among the pathophysiological mechanisms of immune-mediated inflammatory diseases (IMIDs), specific attention has been paid to the abnormal activation of Th17 type immune response related to the dysregulated synthesis of cytokines forming the interleukin (IL)-23 and IL-17 axis. IL-23 blockade is an innovative approach to the treatment of psoriasis and psoriatic arthritis (PsA). Much of the interest has focused on guselkumab (GUS) (TREMFYA, Janssen, Johnson & Johnson, USA), a fully human IgG λ monoclonal antibody (mAb) targeting the p19 IL-23 subunit and the first-in-class treatment approved for patients with psoriasis and PsA. In patients with psoriasis, GUS is at least as effective as other biologic therapies for PsA and is superior to ustekinumab, an anti-IL-12/IL-23 mAb, and secukinumab, an anti-IL-17 mAb. Compared with TNF-α inhibitors, GUS therapy is less likely to cause infections and does not increase the risk of the reactivation of latent TB infection. The new GRAPPA guidelines (2021) recommend GUS (and other IL-23 inhibitors) for patients with PsA resistant to conventional disease-modifying antirheumatic drugs (DMARDs), who have peripheral arthritis, enthesitis, dactylitis, psoriatic skin and nail lesions. The paper discusses new data on the efficacy of GUS in patients resistant to TNF-α inhibitors, its benefits in patients with axial PsA, and safety during the COVID-19 pandemic.

Redes personales como factores de riesgo y protección en mujeres privadas de libertad
Authors:   Universidad Autónoma de Querétaro, México, Rivera-López Maribel , Añaños Fanny T. ,   Universidad de Granada, España
Published: March 2022

El trabajo analiza las redes personales de las mujeres privadas de libertad, identificando factores de riesgo y protección en tres etapas definidas por el ingreso a prisión y orientadas a la reinserción. Se realizó una investigación documental en bases de datos (WOS, Scopus y Google Académico), empleando Mendeley como gestor. Los resultados muestran que, las redes, antes de prisión están permeadas por la violencia y ausencia de apoyo; durante la prisión se dividen en internasexternas y presentan modificaciones relacionales importantes (ruptura de pareja, distanciamiento o no de los/as hijos/as y apoyo de nuevas personas) y; en semilibertad se amplían y mejoran estas, favoreciendo la reinserción social, no obstante, la mayoría regresa al entorno familiar y comunitario inicial enfrentándose a los factores de riesgo asociados.
Prevención del delito y despliegue territorial de la policía en la Ciudad de México. Evidencia a debate
Authors:   Universidad Nacional Autónoma de México - UNAM, Díaz Román Mario Pavel
Published: March 2022

El crimen es un asunto público trascendental. Para hacerle frente se han desarrollado distintas políticas públicas que van desde el despliegue de recursos policiales y castrenses hasta la prevención primaria del delito. En este último caso, y para la Ciudad de México, se han implementado diversas iniciativas; sin embargo, estas no se han estudiado plenamente. Así, el objetivo del texto es mostrar si existe o no correlación entre los módulos de prevención del delito y participación ciudadana y la prevención del delito de la policía de la Ciudad de México con la incidencia delictiva operacionalizada con la variable homicidio. Para ello, se definieron distintos observables empíricos fundamentados en teoría y se ajustaron varios modelos de regresión. Los hallazgos son contraintuitivos, esto es, que en aquellos lugares donde existen módulos se incrementa la probabilidad de ocurrencia de incidentes criminales.

El presente artículo aborda el racismo como una de las expresiones de discriminación con mayores repercusiones en varios dominios del desarrollo de los niños y en la sociedad. Sus consecuencias en la salud física y mental están asociadas con el alcoholismo, consumo de drogas y violencia intrafamiliar. Por ello, se vuelve necesario analizar la forma en que los niños perciben las diferencias de fenotipos, creencias y culturas entre seres humanos y proponer estrategias de intervención que permitan disminuir el racismo desde los entornos escolares. Como instrumentos se presentan dos ejercicios realizados con niños entre diez y doce años, estudiantes de escuelas públicas de tres comunidades localizadas en el estado de Puebla, en México. Los resultados reflejan las construcciones sociales que tienen los niños acerca de diferencias en el color de piel u otras características físicas, así como la percepción de lo que implica ser rico o pobre, teniendo una marcada preferencia hacia personas de tez blanca, cabello rubio y ojos claros, en contraste con las personas de tez negra o morena, cabello negro y ojos oscuros. En la discusión se profundiza en las implicaciones de estos resultados y se presentan algunas estrategias de intervención dirigidas a padres de familia y maestros.
Mitos de violación, creencias que justifican la violencia sexual: una revisión sistemática
Authors:   Universidad Católica del Norte Antofagasta, Chile, Murray Carol , Calderón Carlos ,   Universidad Católica del Norte, Chile
Published: March 2022

En investigación social existe una importante línea de estudios que intentan comprender el fenómeno de la violencia sexual. Un constructo que ha centrado el interés de no pocos investigadores corresponde al de “mitos de violación”. Este concepto agrupa creencias erróneas respecto a la atribución de culpabilidad del agresor y la responsabilidad de la víctima en caso de violación sexual. El objetivo del presente artículo fue realizar una revisión sistemática de los estudios empíricos que reportan evidencia acerca de la relación entre la aceptación de mitos de violación y variables psicosociales. Las bases de datos consultadas fueron, ProQuest, Web of Science, Scopus, PsycINFO, EBSCOhost y JSTOR. Se seleccionaron estudios empíricos en español e inglés publicados entre los años 2009 y 2019. Se encontraron 96 artículos que cumplían con los criterios de selección. Dentro de los resultados el 63,4 % de las investigaciones se desarrollaron en Estados Unidos, 24,7 % en países de Europa y solo 1 % en América Latina. Los hallazgos muestran que los hombres son los que mantienen mayores niveles de aceptación de los mitos de violación en la mayoría de los estudios. Además, se encontraron relaciones con variables como violencia interpersonal y violencia sexual, rasgos de personalidad, variables ideológicas, psicosociales, sexuales y de género. Finalmente se discute sus implicancias y limitaciones.

Published: March 2022

Se presenta la experiencia del proyecto Alerta Verde, una investigación-acción participativa encaminada a afrontar la violencia comunitaria hacia el alumnado universitario en el sureste de México. El proyecto es gestionado por 15 estudiantes voluntarios, con el objetivo de generar el cuidado de la integridad personal del alumnado universitario mediante cuatro acciones que se orientan a propiciar conductas prosociales de cuidado mutuo y solidario que son: determinar sitios inseguros y sitios seguros, medidas básicas para su protección y seguridad, atención en caso de ser víctima del delito e instaurar un pase de lista virtual para monitorear su trayecto de casa a la universidad y viceversa. Al implementar este proyecto 300 alumnos aceptan participar en él. Los resultados evidencian la necesidad de involucrar activamente a la universidad e indican que la vía idónea para hacerlo es a través de los medios y tecnologías de comunicación. Se concluye que se consigue tener participación de la población al solidarizarse para cuidar la integridad personal; se requiere que las acciones sean continuas, preventivas y no como recurso emergente de hechos violentos. Es fundamental apoyar a los estudiantes universitarios que con sus propios recursos y energía han apuntado a una necesidad imperante: el derecho a resguardar su integridad personal en su paso por la universidad.
A CORRIDA ENTRE AS “FINTECHS” E OS BANCOS TRADICIONAIS
Authors: Armelin Danylo Augusto , Rodrigues Nunes Allan
Published: March 2022

A sociedade e as empresas estão inseridas em uma revolução de interconectividade acelerada, promovida pelos avanços tecnológicos existentes e desafiando o uso de aprendizados tradicionais. Como exemplo da citação acima, pode-se dizer que as atuais “startups” buscam conquistar um mercado que estava dominado por outros players, um exemplo é o que ocorre com as “fintechs”, cujo significado representa uma empresa tecnológica que atua no segmento financeiro, sendo seu objetivo conquistar parte desse mercado, desafiando os bancos tradicionais. Diante desse contexto, o estudo teve como objetivo mapear o motivo no qual fez com que o público de 18 a 29 anos optasse pelas “fintechs” ao invés de seguirem com as instituições financeiras tradicionais. Acrescido a isso buscou-se entender o que consideram importante dentro desse cenário de segurança financeira. O estudo teve como base um questionário “on-line”, distribuído através de redes sociais, como o LinkedIn, o Facebook e pelo WhatsApp, o mesmo ficou disponível durante os dias 08 a 11 fev. 2021, com 268 respostas. A devolutiva dessas respostas contribuiu para identificar que a maioria dos entrevistados realizaram essa migração para a plataforma digital, porém ainda se sentem inseguros quanto a segurança das plataformas digitais existentes. Fato esse que sinaliza às organizações digitais a urgência em demonstrar como gerar segurança para seu público tanto quanto uma instituição mais tradicional.
DOS CRIMES CONTRA A ORDEM TRIBUTÁRIA
Authors: Maia de Souza Gabriela
Published: March 2022

O presente estudo objetiva discutir os crimes contra a ordem tributária. Para tanto, aborda o estado social e a justiça tributária; explica o princípio da intervenção mínima aplicado ao Direito Penal Tributário; e detalha sobre a evasão fiscal dando ênfase ao art. 1º, ao art. 2º da Lei 8.137/1990 e à apropriação indébita previdenciária. No desígnio de cumprir o objetivo dessa pesquisa, foi realizada uma pesquisa bibliográfica em doutrinas e na legislação vigente, fontes de pesquisa estas que orientaram a elucidação do tema proposto permitindo concluir que é necessário que o Estado efetive a função social do tributo, garantindo o disposto na Carta Magna e, em consequência, efetivando a justiça fiscal. Sendo assim, para que se garanta a correta aplicação da função social no mundo concreto, por meio do fato gerador, é importante que os crimes contra a ordem tributária sejam combatidos. Assim, com vistas a alterar o atual cenário de desobediência às garantias dos contribuintes, é importante que os operadores do Direito saibam como compatibilizar a necessidade de conseguir melhor eficiência e execução à lei, ao mesmo tempo, protegendo o contribuinte, para ser possível restaurar a equidade tributária.
Differences in body anthropometry between competitively efficient and less efficient junior male handball players
Authors: Adodo S. M. , Agwubike E. O
Published: March 2022

This study was carried out to determine if differences existed in anthropometric and body composition characteristics between competitively efficient (above average) and less efficient (average) junior male handball players. A total of 106 junior male handball players participated in this study. The players were divided into two playing quality or performance groups of above average or (competitively efficient) (n = 26) and average or competitively less efficient (n = 80) levels. A combination of individual players’ quality as determined subjectively by a consortium of national handball coaches and team ranking achieved at a championship were used to achieve this purpose. 22 anthropometric attributes were measured for each subject. Similarly, 6 body composition variables were estimated. The results showed that the above average players were better endowed morphologically than the average players particularly in the Longitudinal Skeleton Dimensionality (LSD), Transverse Skeleton Dimensionality (TSD) and Absolute Voluminosity of the Body (AVB) dimensions. The junior male players at both levels of performance were relatively homogenous in the Subcutaneous Fatty Tissue (SFT). However, the average level players had significantly lower supra spinale skinfold measure (t = 2.57, P < 0.011) than the above average level players. Derived body composition measures of skeletal mass (t = 5.80; p < 0.000); muscle mass (t = 4.87; p < 0.000); and fat free mass (t = 6.59; p < 0.000) were statistically significant in favour of the above average players. The mean (SD) somatotype of all the players (2.04[0.5]; 3.13[1.0]; 3.6[1.1]) were statistically significant. Similarly, the somatotype classification of mesoectomorphic (mesomorphic ectomorph) characterised both levels of players (above average – 2.1[0.4], 2.85[0.8], 3.85[0.8] versus average - 2.01(0.5), 3.23[1.1], 3.54[1.2]) as there were no significant differences in these somatotype components. Results of the study demonstrated that the competitively efficient junior male handball players were significantly differentiated as possessing superior anthropometric characteristics compared to the less efficient junior male handball players.

Authors: Agbonlahor Elvis I. , Hammed Adebisi I.
Published: March 2022

The purpose of this study was to establish the efficacy of a 12-week strength training (ST) programme on handgrip and pinch strength in Type 2 Diabetes Mellitus (T2DM) patients in a tertiary health institution in Benin-City. This study was a pre-test, post-test control group design. A total of 36 T2DM patients participated in the study. Handgrip and pinch strength were measured using electronic hand dynamometer (in kg) and mechanical pinch gauge (in kg) respectively prior to and following a 12-week ST programme. Data generated were analyzed using inferential statistics of one way analysis of variance (ANOVA) and the statistical significance was accepted for p value of <0.05.The findings of the study showed that ST programme had significant effects on handgrip and pinch strength of T2DM patients. It was concluded that ST programme can substantially optimize handgrip and pinch strength of patients with T2DM. Therefore, ST programme should be considered a key element in the management of T2DM patients.
