Minimally Invasive Gingival Recession Treatment by Using Vista Combined With PRF and Collagen Membrane: A Case Report
Authors: Durgapal S. , Shetty M.
Published: October 2023

Root exposure generates major concerns regarding aesthetics and other problems like hypersensitivity and root caries. Gingival recession has traditionally been treated by periodontal plastic surgery, often using soft tissue grafts to fill the defect with excellent clinical results. Advancements in root coverage procedures in the aesthetic zone have led to increasing the ability of clinicians to harness a treatment modality that delivers better outcomes with less surgical morbidity. Collagen membrane is most commonly used for guided tissue regeneration (GTR). On the other hand, platelet-rich fibrin (PRF) has gained popularity due to its simple method of acquisition, low cost and the presence of growth factors. Therefore, this case report describes the treatment of a 38-year-old patient with bilateral multiple Miller’s class I recession defects extending from central incisors to canines by using the vestibular incision subperiosteal tunnel access (VISTA) with PRF and collagen membrane. Clinical parameters such as recession height (RH) and width of keratinised gingiva (WKG) were measured at 6-month and 1-year follow up intervals. The 6-month follow-up revealed optimum root coverage with excellent outcomes for both sites, with an increase in the width of keratinised gingiva and a decrease in the recession height, and less discomfort in the site treated with a PRF membrane. These clinical parameters were maintained at the 1-year follow up. The increase in the width of keratinised gingiva and the decrease in the recession height in both groups and the patient compliance due to this minimally invasive procedure suggests its potential use when aesthetics and patient comfort are of paramount concern.
Voluntariness of social insurance for entrepreneurs – de lege ferenda postulates
Authors: Kolek Antoni Jerzy
Published: October 2023

Subject and purpose of work:

The subject of this paper is to discuss the situation of entrepreneurs in the Polish social insurance system and to present postulates based on conclusions resulting from the analysis of the legal situation of entrepreneurs.

Materials and methods:

The institutional analysis method was used in the paper, which made it possible to present the situation of entrepreneurs in the Polish social insurance system. Based on the analysis of legal acts and the rules of the social security system, the main challenges and issues related to the non-agricultural business activity in Poland were pointed out.

Results:

As a result of the analyses, de lege ferenda postulates have been formulated indicating the need for changes in the area of social insurance for people engaged in non-agricultural business activity.

Conclusions:

Assuming that entrepreneurship is more valuable and that the right to social security can be exercised not only though the insurance process (but also by way of provision, cumulative, or assistance techniques), it is reasonable to introduce voluntary social insurance coverage for people engaged in non-agricultural business activities. With the introduction of voluntariness, it would be necessary to redefine the conditions of eligibility for the statutory minimum pension so that the rights to benefits are not abused.
Ethics and economy during the COVID-19 pandemic
Authors: Wójcicki Włodzimierz
Published: October 2023

Since the beginning of formation of societies (families, tribes), people have looked for ways of arranging mutual relationships so as to improve safety, comfort and development and to be able to differentiate between what is good and what is evil, on the level of everyday life. In their struggles with nature, they sought support in faith. Priests became the intellectual elite, and guidelines how to act became the content of religion. On the higher level of integration, the role of rulers became prominent, and guidelines were sought in the law established by them, with specific contribution from more important subjects (hierarchs). In the background of this process, wise men (philosophers) and theologians made efforts to create and arrange a system of cultivated values in important fields and circumstances of life. The paper deals with the question of ethics in the healthcare sector and during the pandemic.

Authors: Nimară Ciprian
Published: October 2023

Industrial recovery is a very important issue and a useful way to replace the degraded land, industrial objectives and to reuse the abandoned sites. It’s important to use a model of including the abandoned industrial territories in the local economic circuit and to integrate these constructions and landforms in the urban network.

This paper wants to highlight the economic potential of aquatic ecosystems developed on degraded lands, using a rapid method of impact assessment and to show that nature has the ability to recover in a new shape useful for human society.
Exploring the Influence of Sensory Marketing on Brand Perception
Authors: Krupka Zoran
Published: October 2023

The main purpose of this paper is to investigate how the number, perceived intensity, and frequency of sensory involvement in the consumer-brand relationship, impact brand perception. The research was conducted on a sample of 189 respondents from the Republic of Croatia. To test the hypotheses factor and regression analyses were used. The main findings of this research are: a) involvement of multiple senses in the consumer-brand relationship has a positive effect on brand perception; b) the greater the frequency of involving multiple senses in the consumer-brand relationship, the more positive effect it has on brand perception; and c) the higher intensity of sensory involvement in the consumer-brand relationship does not have a significant effect on brand perception. This research contributes to marketing and brand management literature by investigating importance of sensory marketing, more specifically number, perceived intensity, and frequency of sensory involvement on brand perception.

An established biotesting system designed to discover specific features of innovative multifunctional biotextile, encompassing integrated silica dioxide and succinite (Baltic amber) particles, is founded on reproducible, reliable, and relatively fast methods. The main idea starting this study was to create a system of test methods devoted to identification of specific features of biotextile materials designed to preserve living organisms from adverse environmental factors like enhanced electromagnetic radiation of different frequencies, without use of vivarium animals. Cultures of the freshwater macrophyte duckweed (Lemna minor) line Sta2 and fruit flies (Drosophila melanogaster) were chosen as model systems suitable for the study of the influence of electromagnetic field (EMF) radiation. The experiments showed changes of phenotypic features and growth parameters of test objects, as well as induction of point mutations of DNA (for example, insertions or deletions in chloroplast DNA and nucleotide substitutions in nuclear genes). The responses of test organisms induced by EMF were studied using microscopy, flow cytometry, and DNA sequencing methods. On the cell level, a new fast flow cytometry method for biotextile testing was developed: immature gametic (pollen) cell cultures were used as a highly sensitive model system (plant gametic cell response is comparable to human neutrophil response) to study the influence of EMF radiation. The method was based on the measurement of differences of fluorescence intensity between group of cells experimentally affected by EMF radiation and non-affected cells.
Development of a Marker within the Candidate Un8 True Loose Smut Resistance Gene for Use in Barley Breeding
Authors: Šķipars Vilnis , Sokolova Elīna , Seile Sanita , Ruņģis Dainis , Legzdiņa Linda
Published: October 2023

Breeding for resistance to true loose smut infection caused by the pathogen (Ustilago nuda (Jens.) Rostr.) is an economical and environmentally safe way to limit the effect of this pathogen on barley. However, screening for resistance using natural infection can lead to inconsistent results and artificial inoculation is labour intensive, and unless done in growth chambers or greenhouses, can also be affected by environmental conditions, leading to inconsistent phenotyping. Marker-assisted selection of genes conferring disease resistance can increase the efficiency of breeding programmes. A candidate gene for Un8 resistance was used to develop a genetic marker, which was tested on a recombinant inbred line (RIL) population derived from the resistant ‘CDC Freedom’ and the susceptible ‘Samson’ varieties. The RIL population (98 lines) was pheno-typed for resistance to true loose smut by artificial inoculation and genotyped with the newly developed marker. Only one of the 98 RILs tested had a resistant genotype, but was susceptible according to the artificial inoculation results. The marker was also tested in 47 additional barley cultivars and breeding material, and of the five lines with inconsistent results, four were susceptible according to the genotyping results, but were resistant according to the artificial inoculation results, while one line was resistant according to the genotyping results but had a susceptible resistance phenotype.
Nursing Development should Now Become a Priority for Health Systems in Europe
Authors: SKELA-SAVIČ Brigita
Published: October 2023

The vast majority of European countries are struggling to embrace nursing as a profession and as a science. There are still not enough nurses with bachelor’s degrees and advanced practical skills, and clinical specialisations for nurses are being developed at the master’s level. Attention should be paid to recognising nurses as an equal healthcare workforce who need to be empowered to advance their profession and be provided with professional development opportunities. Changes needed include improving pay and working conditions, providing opportunities to improve skills and professional recognition, empowering nurses to deliver care, and harnessing the power of technology to better support nurses. The declining interest in nursing education and the often stereotypical and condescending view of the role and work of nurses on the healthcare team should be a warning signal to all who are working on healthcare reform.
Reliability, Validity and Responsiveness of the Slovenian Version of the Patient Evaluation Measure (PEM-Slo) in Patients with Wrist and Hand Disorders
Authors: BOJNEC Vida , LONZARIĆ Dragan , KLARER REBEC Živa
Published: October 2023

Introduction

The Patient Evaluation Measure (PEM) is a region-specific patient reported outcome measure (PROM) for hand and wrist disorders, first introduced in English for patients with hand surgery in 1995. The purpose of the study was to assess the psychometric properties of the translated and cross-culturally adapted Slovenian version of PEM (PEM-Slo).

Methods

The study was designed as a single-centre observational prospective study conducted from July 2020 to March 2021. The psychometric evaluation was performed on fifty-one patients with miscellaneous hand and wrist disorders. Reliability was tested for internal consistency and test-retest reliability. Convergent and divergent validity, responsiveness, floor and ceiling effect, and interpretability with the determination of minimal detectable change (MDC) and minimal clinically important difference (MCID) were assessed.

Results

The PEM-Slo has excellent internal consistency (Cronbach’s α 0.932) and good to excellent test-retest reliability (intraclass correlation coefficient=0.874). Convergent validity was proved with high to moderate correlations of PEM-Slo with DASH, grip strength and self-care, usual activities, and pain EQ-5D-5L subscales, whereas no correlation of PEM-Slo with EQ-5D-5L mobility and anxiety/depression subscale confirmed divergent validity. The PEM-Slo responsiveness was high (standardised response mean=1.42, effect size=1.25). MDC was 18.01 and MCID was 17.31. No floor or ceiling effect was found.

Conclusion

The PEM-Slo is a reliable, valid and responsive PROM for Slovenian-speaking patients with hand and wrist disorders.

Personzentrierte Psychotherapie während der Covid-19- Pandemie aus der Perspektive von Therapeut*innen: Eine Mixed Methods Studie
Authors: File Norbert , Kulcar Vanessa , Kuntschner Emily , Zeppenfeld Anna , Juen Barbara
Published: October 2023

Die COVID-19-Pandemie erforderte die Umstellung von Psychotherapie auf Distanzmethoden. Basierend auf quantitativen Längs-schnittdaten (N = 101) sowie Expert*inneninterviews mit elf Lehrtherapeut*innen wurden die Perspektiven von personzentrierten Therapeut*innen auf Distanztherapie untersucht. Dabei zeigten sich unterschiedliche Schwierigkeiten bezüglich der Distanz-therapie, insbesondere im Hinblick auf Resonanz und Therapiebeziehung. Obwohl die Präsenztherapie aus diesen Gründen bevorzugt wurde, sahen die Befragten auch Vorteile und befürworteten die Beibehaltung der Möglichkeit von Distanztherapien als Ergänzung. Die Distanztherapie kann dabei durch ihre Niederschwelligkeit die psychosoziale Versorgung der Bevölkerung ver-bessern. Für eine erfolgreiche Umsetzung sind Anpassungen gegenüber der Präsenztherapie nötig. Hierfür können Lehren aus der Pandemiesituation gezogen werden, welche als Empfehlungen zusammenfasst werden.

Gesprächspsychotherapie in Deutschland Vom Höhenflug zum Abstieg?
Authors: Helle Mark
Published: October 2023

In diesem Beitrag wird der Frage nachgegangen, wie es dazu kommen konnte, dass die Gesprächspsychotherapie in Deutschland so sehr an Bedeutung verloren hat. Zunächst wird in groben Zügen die Entwicklung derGesprächspsychotherapie im Kontext der hochschulpolitischen Veränderungen dargestellt. Anhand von drei Thesen wird dann herausgearbeitet, dass (1) die Gesprächs-psychotherapie konträr zu den Professionalisierungsbestrebungen der Psychotherapie im Allgemeinen steht, (2) es ihr nicht gelungen ist, sich konstruktiv mit dem medizinischen Störungsverständnis auseinanderzusetzen und (3) sie sich zu wenig flexibel zeigte, neuere Entwicklungen zu integrieren. Im Ergebnis zeigt sich, dass der aktuelle Status der Gesprächspsychotherapie inDeutschland nicht nur auf fragwürdige Kriterien der wissenschaftlichen Anerkennung und der Beurteilung der Versorgungsrelevanz durch den wissenschaftlichen Beirat bzw. Gemeinsamen Bundesausschuss zurückzuführen ist, sondern auch auf Versäumnisse der Vertreter*innen der Gesprächspsychotherapie.
Die Personzentrierte Psychotherapie im humanistischen Paradigma: Eine Standortbestimmung
Authors: Korunka Christian , Stumm Gerhard
Published: October 2023

National und international wird in den letzten Jahren vermehrt die „Humanistische Psychotherapie“ als ein Sammelbegriff für psychotherapeutische Ansätze mit gemeinsamen Wurzeln vorgeschlagen. Wir versuchen mit diesem Beitrag eine Standort-bestimmung zu dieser Entwicklung aus der Perspektive der Personzentrierten Psychotherapie: Die verschiedenen humanistischen Psychotherapien weisen theoretische Gemeinsamkeiten auf und sie teilen identitätsbildende Merkmale. Die Personzentrierte Psychotherapie kann dabei als zentraler Ansatz innerhalb der humanistischen Psychotherapien verstanden werden. Analog sind Varianten innerhalb der Personzentrierten Psychotherapie als mehr oder weniger eigenständige Entwicklungen innerhalb des Ansatzes zu verstehen. Die Entwicklung der Psychotherapie lebt von diesem Spannungsfeld von Identitätsbildung über Abgrenzung und Gemeinsamkeit. Diesem Spannungsfeld wird nachgegangen, woraus abschließend Thesen gebildet werden, darunter dass eine Humanistische Psychotherapie als methodenintegratives Projekt kritisch betrachtet wird.

Con el objetivo de problematizar las relaciones de género presentes en la educación chilena, se estudian los discursos y las prácticas de académicos, académicas, estudiantes y egresadas de diversas carreras de una universidad chilena. A partir de la información producida mediante una metodología cualitativa de carácter dialógico con estudiantes y egresadas de una universidad chilena, y desde un posicionamiento teórico que concibe como injustas las desigualdades de género, se analiza la elaboración estereotipada de identidades generizadas, la asignación de roles y la distribución de tareas, entre estudiantes, académicos, académicas y egresadas, al momento de cursar sus carreras y en su posterior desempeño profesional. Recurriendo a los resultados de investigaciones previas, que ponen el foco en la formación inicial docente y el posterior desempeño profesional de sus egresadas, se concluye que en las aulas de todos los niveles del sistema educacional se producen desigualdades de género que han comenzado a ser problematizadas y se vuelve necesario investigar con mayor profundidad y extensión
Raíces del cine ensayo en Latinoamérica
Authors: Celedón Bórquez Gustavo , González San Martín Patricia
Published: October 2023

El presente escrito propone que ciertas manifestaciones cinematográficas de los años sesenta y setenta se inscriben dentro de lo que actualmente se llama, con mayor propiedad, cine ensayo. Por un lado, se trata de piezas cinematográficas genuinas y singulares en relación al ensayo cinematográfico europeo, marcando una diferencia importante al constituirse como reflexiones materiales y no estrictamente formales, al decir de la mayoría de los estudios sobre cine ensayo en general. Asimismo, el ensayo cinematográfico latinoamericano de aquellos años establece unas raíces, ligadas a la política, a la crítica y a la estética, muy diferentes a las definiciones actuales, de carácter analítico y lingüístico. Sin llegar a ser moderno, por razones que aquí se discutirán, construye procesos subjetivos alternos, materializa el pensamiento cinematográfico y discute conceptos importantes, como el de la imagen-tiempo en Deleuze. Sin elaborar una lista, el presente escrito genera un marco conceptual con el cual ciertas piezas de la época pueden ser consideradas ensayísticas. Se nombran algunas.
Genealogía del color en objetos públicos

Published: October 2023

El contenido del presente artículo da a conocer la creación de una técnica pictórica e investigativa bautizada como “lijografía”, la cual, a través de una metodología determinada y utilizando un tipo de soporte no convencional como es la lija, permite obtener el pigmento de algunos objetos públicos de la ciudad de Santiago. A través de la descripción de los procedimientos de la técnica, se detallarán algunas categorías apriorísticas y emergentes que se han identificado a lo largo de su desarrollo, revelando, en el caso de las primeras, el “modus operandi” hasta antes de lijar el objeto a intervenir; y en lo referente a las segundas, las situaciones que van surgiendo durante la investigación y que podrían detener transitoriamente la acción en algún momento determinado. A su vez, se detallarán las consecuencias que se manifestaron luego que el confinamiento provocado por la pandemia de coronavirus no permitiera movilizarse libremente por las calles, sugiriendo cambiar temporalmente la manera de proceder.

Tal investigación, que sigue activa al día de hoy, reflexiona sobre la posibilidad de descubrir y ampliar la historia de un objeto público mediante la creación de imaginarios por parte del espectador, permitiendo establecer y desarrollar un relato que se extienda por sobre las descripciones tradicionales del objeto intervenido, dando paso a una apertura de nuevos contextos dialógicos que establecen una relación entre acción lijográfica, mobiliario urbano, espacio público y transeúnte.

La nación y el olvido desde una perspectiva de género: la historia de las enfermeras de la guerra de Malvinas
Authors: Loza Jorgelina , Rigi Luperti Aylem
Published: October 2023

El relato nacional sobre la guerra de Malvinas contiene memorias y experiencias diversas. La historia oficial construyó una memoria masculinizada que no reconoce la participación de las mujeres en la guerra. Desde un marco teórico sobre nación y género, este trabajo busca vincular los significados contemporáneos en torno a la participación de mujeres que ocuparon puestos de enfermeras e instrumentadoras quirúrgicas en la guerra de Malvinas (1982) con la construcción del artefacto cultural nación. Se reconstruye la participación de mujeres en el conflicto a partir de documentos y entrevistas semiestructuradas para reflexionar sobre la omisión de la participación de las mujeres en los relatos oficiales sobre el conflicto. Se busca contribuir a la consolidación de un marco teórico sobre los vínculos entre nación y género. Sostenemos que el olvido de las mujeres en específico que participaron en la guerra se fundamenta en que ocupaban roles vinculados a tareas de cuidado, históricamente feminizados e invisibilizados. El balance entre olvido y reconocimiento que observamos en este caso particular se fue modificando al ritmo de las transformaciones del régimen nacional de género que impactaba en las fuerzas de seguridad.

Efficient Two-Way Coupled Analysis of Steady-State Particle-Laden Hypersonic Flows

A direct solution approach for surface erosion in particle-laden hypersonic flows is extended for use in low-cost two-way coupled solutions of dilute gas-particle flows. The trajectory control volume method, which uses a sparse set of probe particles to predict surface erosion distributions on general vehicles, is reformulated for the solution of source terms by mean trajectory subdivision and computing a flux differencing. The approach is verified successfully against a boundary-layer solution and shown to agree well with experimental measurements. A representative Mars entry case, with conditions and geometry based on the ExoMars Schiaparelli capsule, is solved with the approach to study the impact of two-way coupling on surface heating and erosion. Results indicate that, for realistic loading conditions, heating is largely unmodified compared to one-way coupled results at peak heating trajectory conditions, and no measureable difference is observed in the surface erosion rate. At exaggerated loading conditions high enough to observe coupling effects, the worst-case collisional heating can increase heating by up to 60%.
Three-Dimensional Kinetic Simulations of Carbon Backsputtering in Vacuum Chambers from Ion Thruster Plumes
Authors: Nishii Keita , Levin Deborah A.
Published: October 2023

Gridded ion thrusters are tested in ground vacuum chambers to verify their performance when deployed in space. However, the presence of high background pressure and conductive walls in the chamber leads to facility effects that increase uncertainty in the performance of the thruster in space. To address this issue, this study utilizes a fully kinetic simulation to investigate the facility effects on the thruster plume. The in-chamber condition shows a downstream neutral particle density 100 times larger than the in-space case due to ion neutralization at the wall and limited vacuum pump capability, resulting in a significant difference in the density and distribution of charge-exchange ions. The flux, energy, and angle of charge-exchange ions incident on the chamber wall are found to be altered by the electron sheath, which can only be simulated by the fully kinetic approach, as opposed to the conventionally used quasi-neutral Boltzmann approach. We also examine the effect of backsputtering, another important facility effect, and find that it does not necessarily require a fully kinetic simulation as the incident flux and energy of the sampled charge-exchange ion are negligibly small. Finally, we demonstrate that the carbon deposition rate on the thruster is significantly influenced by the angular dependence of the sputtered carbon, with a nearly 50% effect.
Evolution and Control of Oblique Detonation Wave Structure in Unsteady Inflow

Published: October 2023

Oblique detonation engines have promising applications in hypersonic propulsion due to their compact combustor and high thermal efficiency. However, it is still challenging to achieve stabilized oblique detonation wave in a broad range of flight conditions. This work aims to study the evolution of oblique detonation wave structure in an unsteady inflow with sinusoidal velocity disturbance and to propose a control method to maintain a stable oblique detonation wave in an unsteady inflow. Simulations are conducted for oblique detonation waves in a stoichiometric hydrogen/air mixture, and the detailed chemistry is considered. Results demonstrate that for low-frequency inflow disturbances the autoignition point on the wedge exhibits a smooth trajectory. In contrast, high-frequency inflow disturbances give rise to a new reaction front that subsequently triggers a detonation wave within the induction region, resulting in an abnormal path for the autoignition point. A proportional controller is effectively used to maintain the autoignition point at the desired position, thus stabilizing the oblique detonation wave in unsteady inflow conditions. By implementing the proportional controller, the oblique detonation wave retains relative stability. Moreover, the proportional controller exhibits robust performance in nonideal inflows affected by other types of disturbances, including temperature and attack angle perturbations.
Flutter and Limit-Cycle Oscillations of a Panel Using Unsteady Potential Flow Aerodynamics

Published: October 2023

The potential aerodynamic theory is implemented to model the flow over a flexible panel. The present study compares the more complete unsteady version of the potential flow theory with its simplification known as the linear piston theory for different Mach numbers and the two- and three-dimensional aerodynamic models. The piston theory is “local” in space and time because it assumes the pressure at a spatial point and time only depends on the panel deformation at the same point and time. The full potential flow model includes the effect of the past history of the panel deformation and the spatial distribution of the panel deformation on the pressure at any instant in time and at any point in space. Aeroelastic analysis is made to trace the flutter onset critical condition based on the limit cycle oscillation amplitudes, and the results are compared with the more traditional implementation using piston theory. Conclusions are made based on the use and application of this more complete aerodynamic theory, particularly for near-transonic and hypersonic flow regimes. Subsonic results are also presented in this study.
Isogeometric Dynamic Buckling Analysis of Trimmed and Multipatch Thin-Shell Structures

Published: October 2023

This paper extends our previous work on the isogeometric dynamic buckling analysis of thin-shell structures to the trimmed and multipatch situation where features such as cutouts and stiffeners can be easily incorporated. To be specific, a modified generalized-[Formula: see text] time integration scheme combined with a geometric nonlinear isogeometric Kirchhoff–Love shell element is used to simulate the complex buckling and postbuckling behaviors of thin-shell structures. The developed method can damp properly high-frequency contents while maintaining second-order accuracy in the dynamic buckling analysis. For the integration of arbitrary-shaped trimmed elements, a geometrically exact blending function method is developed to improve the efficiency of the dynamic shell buckling analysis. To deal with multipatch geometries, a penalty-based weak coupling approach is developed, where coupled patches with nonconforming trimmed interfaces or even with prescribed angles, such as stiffeners, can be analyzed. We demonstrate the accuracy, stability, and flexibility of the proposed framework with several numerical examples. In particular, the influences of “free” and “partially free” control points, penalty factor, trimming, as well as different modeling strategies on the dynamic solutions of shell structures are investigated.
