Authors: Hung Ngo Thanh , Nguyen Tran Thuy , Huy Nguyen The , Nam Nguyen Hoang , Lionel CAMILLERI 
Published: July 2021

Introduction: Surgical operative risk of valvular replacement has been widely studied and it has been shown that postoperative complications incidence and mortality increase with patients’ age. The aim of this study was to assess among elderly patients whom underwent surgical aortic valve replacement using various scoring system and Geriatric Assessment Indexes to predict post-operative risk and long-term outcome. Methods and Results: We prospectively evaluated the incidence, over early and late results, of surgical scores and geriatric profile amid 122 intermediate-risk patients, aged 75 years or more who underwent surgical aortic valve replacement. In a univariate analysis, the EuroScore II (OR 1.73, 95% CI: 1.21-2.48, P =0.002), STS score (OR 1.39, 95% CI: 1.03-1.88, P = 0.03) and a Katz index ≤ 5 (limitation of at least one daily living activity) (OR 3.35, 95% CI: 1.08-10.35, P=0.03) were predictors of a 30-day unfavorable evolution. In a multivariate analysis, only surgical scores were predictive factors. At 6 months, 20 patients had deceased or had to be readmitted to hospital. At 10 years, survival was 48 % [IQR 39-57]. The Katz index ≤ 5 was the only geriatric test independent of an unfavorable outcome at 6 months (OR 4.51, 95% CI: 1.25-16.29, P = 0.02) and of a deleterious effect over long-term survival (OR 3.00, 95% CI: 1.58-5.69, P=0.001). Conclusion: In elderly patients, autonomy assessment with the Katz index allows to distinguish a vulnerable population with less beneficial outcomes after aortic valve replacement.

Introduction: This study report the clinical characteristics, surgical indications, surgical technique and initial outcomes of autologous pericardial aortic valve reconstruction using Ozaki’s procedure. Methods: The study included consecutive patients with isolated aortic valve disease who underwent Ozaki’s procedure between June 2017 and December 2019. Aortic valve cups were reconstructed by autologous pericardium using Ozaki’s procedure. Results: Seventy-two patients were enrolled (mean age 52.9 ± 13 years; 53 males) and consisted of 30 aortic stenosis cases, 20 aortic regurgitation cases, and 22 patients with a combination of both 72 patients, a bicuspid aortic valve was present in 20, and 7 patients had infective endocarditis. Surgery was performed via a full or partial sternotomy. The procedure was successful in 70 case, and two patients were converted to prosthetic valve replacement. The aortic cross-clamp time was 106.3 ± 13.8 minutes, cardiopulmonary bypass time was 136.7 ± 18.5 minutes. One patient died of cardiac tamponade in hospital, and two patients underwent reoperation due to bleeding and sternal infection, respectively, were observed during the follow-up period of 30 days. 1-month postoperative echocardiography revealed that one patient had moderate aortic valve regurgitation, max trans-valvular pressure gradient was 16.1 ± 2.3 mmHg, and aortic valve area was 2.5 ± 0.2 cm ². Conclusions: Aortic valve reconstruction using autologous pericardium by Ozaki’s procedure was feasible, good hemodynamics, and can be applied to all lesions of the aortic valve.

Authors: Huy Nguyen The , Nguyen Phan Thao , Nguyen Tran Thuy , Thanh Le Ngoc 
Published: July 2021

Objective: Anteriovenous fistula is a high-flow vascular malformation. Anteriovenous fistula is characterized by a direct connection between an artery and a vein without the presence of a nidus (network of arterial and venous channels). Renal artery aneurysm concomitant with a renal arteriovenous fistula is extremely rare. Case report: We reported the case of a 45-year-old female who has giant renal artery aneurysm combined with high-flow RAVF who presented with gross hematuria. The patient’s embolization of a giant extrarenal aneurism arteriovenous fistula was successfully treated using specialized coils and plug device. Conclusions: Renal arteriovenous fistula is a disease that can lead to serious complications. Treatment of this condition should be initiated promptly after diagnosis. Embolization endovascular is a feasible, efficient and safe method which can maximally retain normal renal function.

Published: July 2021

Objective: Cox Maze procedure is an effective surgical treatment of atrial fibrillation and it is often performed concomitantly with mitral valve surgery. However, some patients still experience atrial tachyarrhythmia post-surgery, which adversely affects heart function as well as their quality of life. Method: We present the case of a 66-year-old female patient who underwent mitral valve replacement with a bio-prosthesis and Cox-Maze procedure; she was later admitted to our center after 14 months due to pneumonia and atrial tachycardia. An electrophysiology study/ intervention was performed. Result: We successfully determined the mechanism and ablated the atrial tachyarrhythmia. The sinus rhythm was restored and was maintained 3 months post-procedure, with amelioration of the left ventricular function. Conclusion: Electrophysiology study with electro-anatomy mapping can help to determine the mechanism of arrhythmia to guide successful ablation of post-operative arrhythmia
Group Formation-Finding-Your-Matching-Card in a Collaborative Learning Classroom
Authors: Liang Su 
Published: July 2021

This paper presents a non-traditional strategy of group formation that engages students in utilizing prior learned knowledge to solve problems at a collaborative learning classroom. Through the grouping process students communicate mathematical thinking with their peers and physically moving around to find their matching cards and group parteners. The grouping process warms up students to launch an active learning mode. Although the grouping method was implemented in the mathematics content course for preservice elementary teachers and the capstone course for preservice secondary mathematics teachers, it could perfectly fit different types of classrooms including grades K-12 or college level.
When learning Italian as a Second Language, tourism and technology go hand in hand
Authors: Zingaro Anna , Cervini Cristiana 
Published: July 2021

This paper aims to describe the development of CALL-ER, an application for mobile devices, produced within the CALL-ER project (Context-Aware Language Learning in Emilia Romagna). An ever-increasing availability of applications for language learning that meet the different learning needs of users, as well as the ubiquitous wireless communication, led applications for mobile devices to become gradually more context-aware. This means that language is acquired by users through the direct experience with the local context where they are. An example in this regard is represented by the CALL-ER mobile application, that supports mobility students through the incidental learning of Italian language and culture in the city of Forlì. We will begin this contribution with an outline of the theoretical underpinnings that supported the project and a presentation of the project itself. We will then present the first stage of the project, during which the application was developed before its first testing. At this point, an overall description of the application will be given. A special attention will be paid throughout this paper both to how language learning has been conceived through experiential tourism and to the multimodality of the contents.
Embracing the digitalization of research education? How social science research education was influenced by the COVID-19 pandemic
Authors: Prandner Dimitri , Hasengruber Katrin 
Published: July 2021

The COVID-19 pandemic led to a strong digitalization push at university level teaching. The latter had to be converted to distance modes quickly. This paper discusses the consequences of these developments for the field of social science research education, a discipline where the personal interaction between lecturers and students traditionally plays a major role in the transfer of knowledge and competences. Accordingly, we ask whether lecturers accepted distance learning as part of their work and if they will implement the associated digital teaching modalities into their regular teaching repertoire in the future. Furthermore, indicators shaping the acceptance of future distance teaching are explored. The article is based on a continuous online survey of lecturers (n = 169) who teach social science methods and methodology at Austrian public universities. The results of this study show that more than 40 % of the sample with or after the experience of distance teaching will retain some aspects of it in their teaching due to the CODIV-19 pandemic. In particular, the evaluation of the preparation effort, the interaction with students and the attitude toward new didactic methods play a central role in the acceptance of distance teaching.

Authors: Colegrove Patrick Tod , Westergard Tammy 
Published: July 2021

Emerging technologies in education are offering new tools for teaching and learner engagement. Today’s study and practice can include use of digital technologies far beyond looking at a flat screen: virtual reality, augmented reality, interactive 3D objects and 360 video can provide immersive and impactful teaching and learning. There are a variety of definitions for these “realities” but the overarching impact is one of powerful, immersive, visual learning. Immersive virtual reality in a learner-centric environment can provide more presence and engagement for students, enabling the possibility of enhanced learning experiences relative to conventional classroom practices. This paper presents early results of a pilot study leveraging the possibilities of VR technology in service to an existing program of study in allied health services:graduates surveyed report high degrees of confidence in course materials learned by means of the custom VR components developed, reporting the adjunct course materials substantially helped learners in understanding otherwise difficult to grasp concepts of the course.
Reverse Metadesign: Pedagogy And Learning Tools For Teaching The Fashion Collection Design Process Online
Authors: Casciani Daria , Colombi Chiara , Vacca Federica 
Published: July 2021

The present article discusses the experience of redesigning the pedagogy and learning tools of a pillar course at the School of Design of XXX, the Metadesign studio course. Metadesign is a design methodology that leads to the concept definition of a new product or service, through a research process that synthesizes design goals, technological and productive constraints, market context and consumption trends for a consumers’ group of reference. It represents a unique methodological approach characterizing the design education as it provides a consolidated research practice able to support the design process. The course structure foresees the reconstruction in phases and successive elaborations of all the elements of context that come into relation with the object of the design process (product, space, service, communication artifact…) influencing its characteristics and creating the “abacus” of elements that make its development possible. In line with the ever-increasing need to reshape the whole education system through the paradigms of digital transformation, and due the acceleration the COVID-19 emergency pushed to the request for on-distance courses, the article presents a renewed reverse course structure, highlighting strengths and opportunities for further improvements that represent a solid base for innovating a fashion design education.

Published: July 2021

Introduction (problem statement and relevance). The airbag belongs to the passive vehicle safety system (SRS - Supplementary Restraint System) and is the most important (together with the seat belt) restraint system that protects the driver and passengers in a collision with static or moving objects. The main task of the SRS is to minimize injuries to the driver and passengers and reduce deaths in various road traffic accidents. For the development and testing of modern high-tech airbag modules, it is necessary to have informative theoretical and experimental methods for studying the non-stationary processes of their functioning.The purpose of the study was to develop an experimental-theoretical research method based on modern highly informative tools of experimental physics of fast processes and numerical methods for continuous media dynamics.Methodology and research methods. To study the functioning dynamics of vehicle airbag modules, an experimental method for determining the kinematic and acoustic parameters has been developed and implemented, and a mathematical model of an airbag functioning process has been formulated and implemented in the LS-DYNA environment with the help of corpuscular particles method.Scientific novelty and results. The created experimental-theoretical method allowed both to simulate the functioning processes of the developed and tested airbag modules, and to carry out field tests of these modules. In addition, the experiment made it possible to carry out a detailed verification of the numerical method for calculating the airbag operation, on the basis of which it was also possible to perform numerical calculations interaction of the airbag and an anthropometric dummy model.Practical significance. The developed method for studying the processes of airbag modules functioning is an important and necessary component of creating a scientific, technical and experimental base for the development and production of passive safety systems.

Published: July 2021

Introduction (problem statement and relevance). Hydrocarbon emissions from vaporizationtank fuel contribute significantly to the total emissions of hazardous substances from vehicles equipped with spark ignition engines. To meet the established standards for limiting hydrocarbon emissions caused by evaporation, all modern vehicles use fuel vapor recovery systems, the optimal parameters of which require the availability and application of mathematical models and methods for their determination.The purpose of the research was to develop a model of vapor generation processes in the car fuel tank and a methodology for determining the main quantitative parameters of the vapor-air mixture.Methodology and research methods. The analysis of the processes of vapor generation in the fuel tank was carried out. It was shown that the mass of hydrocarbons generated in the steam space was directly proportional to its volume and did not depend on the amount of fuel in the tank.Scientific novelty and results. New analytical dependences of the vaporization amount on the saturated vapor pressure, barometric pressure, initial fuel temperature and fuel heating during parking have been obtained.Practical significance. A formula was obtained to estimate the temperature of gasoline boiling starting in the tank, depending on the altitude above sea level and the volatility of gasoline, determined by the pressure of saturated vapors. Using the new equations, the vaporization analysis in real situations (parking, idling, refueling, explosive concentration of vapors) was carried out.

Carreras de la memoria: corporalidad, dinamismo y performatividad en Campo de Mayo de Félix Bruzzone
Authors: Cantoni Federico 
Published: July 2021

In the heterogeneous corpus of works published by sons of Argentinean desaparecidos one of the most interesting and original contribution are the texts written by Félix Bruzzone. The aim of this article is to outline the main characteristics of the author’s style and then to analyse his last novel Campo de Mayo (2019). The novel actually originates as another type of text, a performance, so first of all, the peculiarities of this textuality will be identified, in order to reflect on the mechanisms that intervene when a performance is transposed into a novel. It will be demonstrated that the novel keeps many elements of the performance, all linked to the theme of the search for disappeared parents, that ensure that the dynamic corporeal characteristic of the hipotext is kept in its novelisation, in order to create a discourse that through the body of the protagonist displays all the contradictions and paradoxes that this impossible search implies, using de textual image of the moving body to give an account of the complex dynamics of identity definition concerning sons of desaparecidos.

Authors: Tim Penulis Laporan  
Published: July 2021

Perekonomian Jawa Timur pada semester II 2017 menguat dibandingan semester sebelumnya, diiringi dengan tekanan inflasi Indeks Harga Konsumen (IHK) yang lebih rendah dan stabilitas sistem keuangan daerah masih terjaga. Akselerasi ekonomi Jawa Timur pada semester II 2017 terutama disebabkan oleh perbaikan kinerja eksternal dan peningkatan investasi. Dari sisi inflasi, berakhirnya penyesuaian tarif listrik dengan daya 900VA menopang rendahnya tekanan inflasi IHK (yoy) Jawa Timur dibandingkan paruh pertama 2017. Lebih lanjut, terjaganya stabilitas sistem keuangan Jawa Timur tercermin dari terkendalinya NPLperbankan dan terjaganya rasio keuangan korporasi.
Akselerasi kinerja perekonomian Jawa Timur yang lebih tinggi tertahan oleh perlambatan kinerja konsumsi swasta dan peningkatan impor luar negeri. Pada Semester I 2018, kinerja ekonomi Jawa Timur diperkirakan tetap tumbuh tinggi sebagaimana pertumbuhannya pada paruh kedua 2017. Optimisme tersebut ditopang oleh potensi peningkatan konsumsi swasta dan pemerintah sejalan dengan berlangsungnya Ramadhan, Idul Fitri, dan Pemilihan Kepala Daerah (Pilkada). Inflasi IHK Jawa Timur diperkirakan kembali pada sasaran inflasi 3,5%±1% seiring meredanya tekanan inflasi di kelompok administered prices, terjaganya inflasi inti, dan rendahnya potensi peningkatan tekanan inflasi kelompok volatile food. Lebih lanjut, sejalan dengan nasional, stabilitas sistem keuangan dan kinerja perbankan Jawa Timur diperkirakan masih stabil pada paruh pertama 2018.
Title: Caring Conversation Framework to promote person centred care: synthesising qualitative findings from a multi- phase programme of research
Authors: Dewar Belinda 
Published: July 2021

Background Little is known about how to support practitioners to enhance their interpersonal conversations to be more compassionate, person centred and relational with others. The Caring Conversations (CC) framework was empirically derived to address this issue and comprises seven attributes (be courageous, connect emotionally, be curious, consider other perspectives, collaborate, compromise and celebrate).ObjectiveThis paper synthesises the qualitative findings from a multi-phase programme of research, which implemented the CC framework across a variety of health and social care settings (acute hospitals, community, and residential care). It explores the perceived impact of the CC framework on staff and their practice.MethodsSecondary analysis was conducted on the qualitative findings in the final reports of 5 studies, involved in the implementation of the CC framework.ResultsThe analysis showed consistent positive outcomes for staff in their interactions with patients, families and others; including greater self-awareness during interactions, development of stronger relationships, and more open dialogue that supports relational practice. The secondary analysis confirmed the applicability of the framework across a number of different settings, strengthened confidence in its value, generated fresh insights to inform further research, and developed a deeper insight into the attributes of the framework and its application.ConclusionsPolicy and research advocate compassionate care and relational practice, but do not state how this can be delivered in practice. By synthesising the findings from 5 studies undertaken in a variety of different settings, we can be more confident in the value of the CC framework to ensure best practice.
