ObjectiveTo study the clinical effect and influencing factors of kyphoplasty in the treatment of osteoporotic thoracolumbar compression fractures (OTCF) complicated with type 2 diabetes mellitus (T2DM).MethodsA total of 472 patients with OTCF complicated with diabetes who were enrolled in our hospital from January to December 2019 were selected as the study subjects, and all patients were treated with percutaneous kyphoplasty (PKP). The effects of gender, age, smoking, drinking, body mass index (BMI), bone mass density (T score), fasting blood glucose level, fasting C-peptide, glycosylated hemoglobin, course of T2DM, vertebral segment and surgical instrument on postoperative improvement were analyzed. The quality of life was evaluated by visual analog score (VAS) and Oswestry disability index (ODI) before PKP and 7 days, and 6 months after PKP, and the patient satisfaction was assessed by the modified Macnab criteria at 6 months postoperatively.ResultsThe overall excellent and good rate of evaluation result was satisfactory. In multivariate regression, independent risk factors for poor patient satisfaction included: age ≥70 years (odds ratio (OR) = 2.298, 95% confidence interval [CI] 1.290–4.245, P = 0.025), fasting blood glucose ≥8 mmol/L [OR = 2.657, 95%(CI) 1.288–4.121, P = 0.016], glycosylated hemoglobin ≥6.5 mmol/L [OR = 3.438, 95%(CI) 2.543–4.628, P = 0.001], duration ≥8 years [OR = 1.732, 95%(CI) 1.471–3.253, P = 0.019] and Kyphon instrument [OR = 1.472, 95%(CI) 1.112–2.228, P = 0.018] were independent influencing factors of OTCF complicated with DM.ConclusionKyphoplasty for patients with osteoporotic thoracolumbar compression fractures complicated with diabetes can achieve a satisfactory clinical effect, the curative effect is affected by many factors, attention to these factors can improve the clinical effect.
Політична коректність – соціальний конструкт сучасного мовного простору публічного управління
Authors: Yemelyanov Volodymyr , Yevtushenko Natalia 
Published: February 2023

У статті розглянута політична коректність, як соціальний конструкт повсякденного сучасного політкоректного мовного простору публічного управління, що була запропонована і розроблена у 60-х рр. ХХ століття Пітером Бергером і Томасом Лукманом.
Доведено, що в публічному управлінні в умовах комунікації, дотримання політкоректності спрямоване на те, щоб знайти нові способи мовного вираження замість тих, які торкаються почуттів та гідності окремої людини, стосовно раси, статі, віку, стану здоров’я, соціального статусу, зовнішнього вигляду та ін.
Зазначено, що політкоректність, як нормований мовний спосіб поведінки, притаманний будь-якому суспільству, зокрема українському, тому що пов’язаний з моделями коректної поведінки членів суспільства, а з точки зору теорії соціального конструктивізму має певний потенціал конструювання уявлень про реальність життя населення.
Підкреслено, що уявлення про політкоректність, як соціальний конструкт публічного управління засновано на тому, що люди в суспільстві засвоюють загальну точку зору щодо більшості речей, що існують в суспільній свідомості, як частину наданої соціальної реальності, що існує об’єктивно, але завжди є суб’єктивною тому що формується, інтерпретується, конструюється акторами в процесі комунікації.
Визначено, що політкоректність, як надана нам реальність і водночас конструкт соціальної реальності, створюється, конструюється та засвоюється людьми у вигляді політкоректних цінностей і норм, для того щоб в процесі комунікації, утримуватися від висловів, поглядів і дій, які можуть бути образливими для інших членів суспільства. Політкоректність є формою соціальної організації, що конструюється на суб’єктивних знаннях людей в процесі їх діяльності, та є символічною структурою, що інтегрована в модель політкоректної мовної поведінки.
В подальших дослідженнях пропонується вивчення політкоректності через механізми активного залучення громадськості до процесів публічного управління, зокрема об’єднаних територіальних громад.

Published: February 2023

Background
Ovarian hyperstimulation syndrome (OHSS) occurs in women receiving fertility treatments. Moderate and severe OHSS cases are required to be admitted to hospital for treatment. The incidence of moderate and severe OHSS and the characteristics of these cases are unknown in China. We aimed to assess the incidence of moderate and severe OHSS in national databases from China between 2013 and 2017.

Methods
We extracted moderate and severe OHSS cases from the Hospital Quality Monitoring System, the nationwide inpatient data collection system. We used ovum pick-up (OPUbaidu) cycle data from the annual report of China’s National Health Commission, developed on the basis of OPU data collected by National ART Management Information System. Overall incidence of moderate and severe OHSS (women aged 20 to 50 years) and year-specific incidence by each calendar year in China were calculated. We also investigated the age distribution in OHSS and OHSS with different comorbidities.

Results
We extracted 18,022 eligible patients with moderate or severe OHSS and 1,581,703 OPU cycles. The overall incidence of moderate and severe OHSS between 2013 and 2017 was 1.14%. The year-specific moderate and severe OHSS incidence was 1.1% in 2013, 1.4% in 2014, 1.4% in 2015, 1.1% in 2016, 0.9% in 2017, respectively. Women aged 26 to 30 years accounted for 48.4% of OHSS cases, followed by women aged 31 to 35 years (30%) and 20 to 25 years (14.2%). The age distribution pattern was consistent across OHSS with different comorbidities.

Conclusions
This study reported the incidence of moderate and severe OHSS in China using nationwide data for the first time. Our findings support that women aged under 35 years receiving assisted reproductive technology need more attention than other age groups in terms of OHSS risk control.
Structure of the space of GL4 (Z2)-coinvariants Z2 ⊗ GL4 (Z2) P H∗ (Z42,Z2) in some generic degrees and its application
Authors: Võ Phúc Đặng 
Published: February 2023

<p> Let $A$ denote the Steenrod algebra at the prime 2 and let $k = \mathbb Z_2.$ A very difficult problem in algebraic topology is to determine a minimal set of $A$-generators for the polynomial ring $P_q = k[x_1, \ldots, x_q] = H^{*}(k^{q}, k)$ on $q$ generators $x_1, \ldots, x_q$ with $|x_1|= |x_2| = \cdots = |x_q| = 1.$ Equivalently, one can write down explicitly a basis for the cohit space $\pmb{Q}^{q} := k\otimes_{A} P_q$ in each non-negative degree $n.$ This subject, which has now a long history, is the content of the classical "hit problem" proposed in [Abstracts Papers Presented Am. Math. Soc. \textbf{833} (1987), 55-89]. Furthermore, it is closely related to the $q$-th transfer homomorphism $Tr_q^{A}$ constructed by William Singer in [Math. Z. \textbf{202} (1989), 493-523]. This $Tr_q^{A}$ passes from the space of $G(q)$-coinvariant $k\otimes _{G(q)} P_A((P_q)_n^{*})$ of $\pmb{Q}^{q}$ to the $k$-cohomology group of the Steenrod algebra, ${\rm Ext}_{A}^{q, q+n}(k, k),$ where $G(q)$ denotes the general linear group of degree $q$ over the field $k,$ whereas $P_A((P_q)_n^{*})$ is the primitive part of $(P_q)^{*}_n$ under the action of $A.$ Particularly, Singer conjectured that $Tr_q^{A}$ is a monomorphism, but this remains unanswered for all $q\geq 4.$ Accordingly, the aim of the present study is to deal with the Singer conjecture for rank 4 in some certain internal degrees. Specifically, by the usage of the techniques of the hit problem in four variables, we explicitly determine the structure of $k\otimes _{G(4)} P_A((P_4)_{n}^{*})$ in some generic degrees $n.$ Then, applying these results and a representation of $Tr_4^{A}$ via the lambda algebra, we state that Singer's conjecture is true for rank $q = 4$ in respective degrees $n.$ This has contributed to the final proof of Singer's conjecture in the rank 4 case.</p>
Performance Analysis of Spectral Amplitude Coding Methods in Fiber Optical Communication System

Published: February 2023

<p> This study analyzes optical code division multiplexed access system coding with two different types of spectral amplitude coding (SAC): Double Weight (DW) codes and Multiple Diagonal (MD) codes. These two encoding types differ in code structure and channel bandwidth length (the number of wavelengths representing the channel's bandwidth), as well as Q-Factor, BER, and MAI values. This study analyzes systems with different number of users over single-mode optical fiber and presents a comparison of both. DW codes have a shorter length code than MD codes, and although this technique can generate unique code words for each user, it will break the system using MD encoding. This is another reason to increase bandwidth for MD codes. </p>

Published: February 2023

<p>The design and development of sub-Terahertz (THz) communication systems entail the need for new channel models that can precisely predict channel characteristics at such frequencies (>100 GHz) in outdoor and dynamic environments. This work proposes a novel hybrid-stochastic ultra-wideband channel model for sub-THz bands, developed within the framework of a class of spatio-temporal stochastic processes called ambit-process. The proposed model is capable of supporting bandwidths of upto 10 GHz. The spatio-temporal evolution of the ambit framework allows for a reasonably accurate and tractable characterization of the fading statistics and multipath propagation of a cellular channel with good spatial consistency. We leverage a recently proposed low-complexity ambit-process based channel simulation algorithm with necessary modifications to study key features of the outdoor sub-THz channel like associated diffused scattering, molecular absorption, spatio-temporal correlations, and consistency between the time-evolving delay and Doppler of the multipaths. Simulation results on path loss, delay spread, and channel correlation indicate that the ambit model accurately captures the typicalities of an urban microcellular sub-THz channel and agrees well with the measurement results reported in the literature. </p>

Published: February 2023

<p>Noise can be modeled as a sequence of random variables defined on a probability space that may add to a given dynamical system T that is a map on a phase space. In the nontrivial case of dynamical noise {ε<sub>n</sub>}<sub>n</sub>, where ε<sub>n</sub> ∈ N(0, σ<sup>2</sup>) and the system output is x<sub>n</sub> = T(x<sub>n−1</sub>, x<sub>n−2</sub>, ..., x<sub>0</sub>)+ε<sub>n</sub>, without any specific knowledge/assumption on T, the quantitative estimation of noise power σ<sup>2</sup> is a challenge. Here, we introduce a formal method, based on nonlinear entropy profile, to estimate the dynamical noise power σ<sup>2</sup> without knowledge on the specific T function. Time-series generated from Logistic maps and Pomeau-Manneville systems under different conditions are used to test the correctness of the method. Results demonstrate that the proposed estimation algorithm properly discerns different noise levels with no a priori information. </p>

Knowledge and skills. A possible meeting
Authors: Piccinno Marco 
Published: February 2023

The essay focuses on the relationship between knowledge and skills, to identify the anchoring points that allow a non-antagonistic and integrated interpretation of these two aspects of learning. The principals on which to build this mediation processes are identified in the distinction proposed by Gardner (2009) between Matter (the set of knowledge related to a scientific domain) and discipline (the processes from which the individual sciences build knowledge around their object of study), as well as in the concept of Abitus (Dewey, 2014; Baldacci, 2006) understood as the set of permanent provisions of subjectivity.

Saperi e competenze. Un incontro possibile.
Il saggio focalizza la riflessione sul rapporto tra saperi e competenze, allo scopo di individuare i punti di ancoraggio che consentono una interpretazione non antagonista e integrata di questi due versanti dell’apprendimento. I presidi sui quali costruire i processi di mediazione vengono individuati nella distinzione proposta da Gardner (2009) tra Materia (l’insieme delle conoscenze afferenti a un dominio scientifico) e disciplina (i processi a partire dai quali le singole scienze costruiscono conoscenza intorno al loro oggetto di studio), nonché nel concetto di Abitus (Dewey, 2014; Baldacci, 2006) inteso come l’insieme delle disposizioni permanenti della soggettività.
On competences, and in particular on personal competences often called soft skills: their role in the world of work
Authors: Pellerey Michele 
Published: February 2023

Recently there has been a wide debate on the role of so-called noncognitive skills, a misnomer for the personal skills needed to cope positively with personal, social and professional life. In this contribution an attempt is made to clarify their meaning, prospect their development and possible evaluation. Reference is made in this framework mainly to the world of work, in which they are more specifically referred to as soft skills.

Sulle competenze, e in particolare su quelle personali dette spesso soft skills: il loro ruolo nel mondo del lavoro.
Recentemente si è sviluppato un ampio dibattito sul ruolo delle cosiddette competenze non cognitive, espressione impropria per indicare le competenze personali necessarie per affrontare positivamente la vita personale, sociale e professionale. In questo contributo si cerca di chiarire il loro significato, prospettare un loro sviluppo e una loro possibile valutazione. Si fa riferimento in questo quadro soprattutto al mondo del lavoro, nel quale esse sono più specificatamente denominate soft skills.
Medios de sustento económico, social y cultural de mujeres “canasteras” vendedoras de productos agrícolas en un mercado tradicional

Published: February 2023

En la actualidad, cada vez es más visible el rol protagónico de las mujeres rurales en la sociedad. Son evidentes las complejas y diversas estrategias que realizan para ganarse la vida y para ser reconocidas como agentes económicos y sociales de transformación, y como piezas clave del desarrollo rural; sin embargo, aún persiste disparidad en su participación políticosocial. El objetivo del presente trabajo es comprender, desde el enfoque orientado al actor, los medios de vida de las canasteras, creadoras y vendedoras de productos agrícolas en el mercado tradicional Vicente Obregón en la ciudad de Acayucan, Veracruz en México. Se realizó un trabajo etnográfico durante un periodo de seis meses, durante el cual se realizaron entrevistas a profundidad e historias de vida. Las mujeres vendedoras de productos agrícolas en mercados tradicionales son parte del sector económico informal. A partir de ello se identificó que, a pesar de que esta actividad es su principal sustento, las canasteras no pueden acceder a una mejor calidad de vida y que, en su quehacer cotidiano, no sólo intervienen prácticas económicas, sino que éstas se convierten en dinámicas sociales y en reafirmaciones simbólicas. Asimismo, existe una fragmentación en la estructura del papel que juegan las mujeres rurales en la sociedad; las mujeres canasteras están reestructurando su rol de género tradicional asumiendo un papel social y económico más importante. Son agentes del cambio, tienen un rol en el mercado, y representan una parte fundamental en la alimentación de la sociedad.
Jóvenes Construyendo el Futuro: Análisis y recomendaciones sobre el diseño de la política pública
Authors: Muñoz Chávez Rosa Leticia , Muñoz-Chávez J Patricia , Valle Cruz David , Barrios-Quiroz Héctor 
Published: February 2023

El Programa Jóvenes Construyendo el Futuro surge como una política para combatir el desempleo, subempleo y los bajos salarios en la población joven. El programa pretende capacitar y vincular a los jóvenes con el sector productivo, con la finalidad de que encuentren empleos estables y mejor remunerados. Algunos de los efectos potenciales de esta política pública podrían relacionarse con el crecimiento económico e impactar en otros aspectos sociales (vivienda, salud, seguridad). Derivado de ello, el presente escrito tiene como objetivo realizar un análisis integral del programa, utilizando el modelo de etapas de Subirats, así como la definición de actores, recursos, reglas y componentes de la política pública y el modelo de Bardach, lo que permitirá efectuar algunas recomendaciones. Los hallazgos muestran que uno de los aspectos a mejorar en la implementación de este programa es el establecimiento de mecanismos de evaluación, por lo que se sugiere una modificación en las reglas de operación del programa, que incluyan los indicadores de evaluación de resultados, la focalización de beneficiarios, la creación de incentivos fiscales para los centros de trabajo participantes y una definición precisa de los planes de capacitación que potencien la vinculación con el sector productivo.
A COMPARATIVE REVIEW OF THE TRANSFORMATION OF ECONOMIC INDICATORS IN A TRANSITIONAL PERIOD IN THE HISTORY OF UKRAINE’S INDEPENDENCE
Authors: Romanovskyi Oleksandr O. 
Published: February 2023

The paper provides a comparative review of the transformation of economic indicators in a transitional period in the history of Ukraine’s independence. The illustration of comparison of the dynamics of economic development of Ukraine, Poland and Kazakhstan during the period from 1990 to 2017 is given. Analysis of political, social and economic problems of Ukraine in the period of its independence is carried out. Author’s vision of the important prerequisites for the further creation of conditions for the sustainable development of Ukraine is formulated. These prerequisites are based on fact that the last four years of political, social and economic development of Ukraine in a state of unceasing military aggression, constant shelling of the territory of Ukraine in the Donbass region, leading to the death of Ukrainian citizens, attacks on ships in the Black and Azov Sea adversely affect the entire spectrum of life and activities of Ukraine.
The author stated that in order to create the necessary conditions for the sustainable development of Ukraine the following prerequisites are indispensable: ​​the eradication of the oligarchic clans; overcoming corruption at all levels – “from the bottom to the top”; the creation of a “legal country”; the creation of a “civil society”; transition to “green economy”. Also the author underlined that to solve all the problems without exception in order to create conditions for the sustainable development of Ukraine (paragraph 2), it is necessary to solve the priority task – “create a moral and ethical Ukraine”. This is possible only in the conditions of moral and ethical education of the entire population – “from the cradle” to the “honorable old age”.

Published: February 2023

El objetivo general es analizar la importancia de desarrollar resiliencia en los estudiantes del sector rural. El estudio se lleva a cabo a través de la metodología de la revisión sistemática. Se seleccionaron 50 investigaciones científicas, clasificadas en 43 artículos científicos y 7 tesis doctorales, de las cuales 7 corresponden al contexto de Colombia, 4 Chile, 2 Cuba, 4 Ecuador, 7 España, 11 Perú, 8 México, 1 África, 1 Israel , Reino Unido, 1 USA. Se organizó la información teniendo en cuenta el título, nombre de la revista, número de la muestra, las observaciones finales, el país, el enfoque de cada investigación. Los temas tratados por los autores de las 50 fuentes bibliográficas seleccionadas para la realización de esta revisión sistemática son salud emocional - resiliencia, educación - resiliencia, Familia - resiliencia, Vulnerabilidad – resiliencia, resiliencia – rendimiento académico y Afectividad – resiliencia. Siendo la más común salud emocional abordado por 16 autores y el menos común afectividad y resiliencia abordado por 2 autores.Los resultados de la revisión sistemática dejaron en evidencia que, en las escuelas de sector rural, le restan atención a la salud emocional y la educación afectiva. para que sea posible el desarrollo de resiliencia en los estudiantes de sector rural o urbano, es preciso que estos cuenten con una buena salud emocional, apoyo familiar o un modelo positivo a seguir. Se concluye que hay personas que desarrollan resiliencia sin necesidad de ser estimuladas, sin embargo, es una capacidad que todo ser humano puede desarrollar. Para la formación de seres resilientes en las escuelas del sector rural es importante tener motivación, claras metas y buena autoestima.

Authors: Tello Yancha Patricia Anabel , Céspedes Guachamboza Danilo Alejandro 
Published: February 2023

La dependencia emocional es un estado psicológico caracterizado por un comportamiento en el que la persona realiza esfuerzos desmedidos para no ser abandonado, exige demasiada atención y presenta dificultad en la toma de decisiones, mientras que la resiliencia es una capacidad personal para afrontar los problemas y abstraer un aprendizaje. El objetivo del estudio fue determinar la relación entre dependencia emocional y resiliencia en estudiantes universitarios de la Carrera de Psicopedagogía de la Universidad Técnica de Ambato, mediante un estudio cuantitativo, descriptivo de alcance correlacional y de corte transversal con una muestra de 154 estudiantes (76 hombres y 78 mujeres) escogidos por un muestreo no probabilístico por conveniencia, a quienes se les aplicó el Inventario de Dependencia Emocional CDE y la Escala de Resiliencia de Wagnild y Young. Los resultados mostraron prevalencia de niveles bajos de dependencia emocional y niveles elevados de resiliencia, no se hallaron diferencias estadísticamente significativas entre la dependencia emocional, resiliencia y la edad, además se determinó una correlación inversa proporcional entre la dependencia y la resiliencia (Rho=-,257 p< 0.001).
