Authors: Sarkisova Yuliia
Published: October 2021

In this paper the results of modern scientific researches are analyzed and the possibilities of the method of establishing the amount of K+ and Na+ in the vitreous body (VB) of a person for solving problems of practical forensic medicine are studied.

The aim of the work. To investigate the possibilities of accurately establishing the time since death (TSD) by determining the amount of electrolytes (K+ and Na+) of human VB.

Materials and methods. VB samples from 120 deaths due to cardiovascular pathology (exclusion criteria: eyeball injuries, traumatic brain injury, exogenous intoxications) were studied. The study of the test material was performed on an analyzer of electrolytes and gases ROCHE COBAS B121. The main task was to analyze and establish the dependence of the change in the amount of K+ and Na+ of the VB on the TSD. Statistical processing of the obtained results was performed using Statistica software.

Results. In all cases, on average in the first 6 hours, its amount was 7,4 mmol/l, after 6-12 hours – 9,8 mmol/l, after 12-18 hours – 12,1 mmol/l, after 18-24 hours – 16,5 mmol/l, after 24-36 hours – 20,2 mmol/l, after 36-48 hours – 25,3 mmol/l. The amount of Na+ ranged from 120 to 200 mmol/l.

Conclusions. It is established that the number of electrolytes of the VB of the human eye naturally changes with increasing postmortem interval, which allows to use this technique to determine the TSD. In particular, the accuracy of setting the DNS by the number of K+ – 4-6 hours between 1 and 18 hours after death. There is an increase in the range of accuracy at a later date of the TSD.

Digital storytelling has been around in foreign language contexts for at least two decades and showed to be a promising technique for teaching different language skills. This study aimed at investigating the effect of using two types of digital storytelling, i.e. asynchronous and synchronous digital storytelling, on the EFL learners' speaking performance in terms of accuracy and fluency. To this end, a quasi-experimental design with an experimental and a comparison group was devised. Sixty-five intermediate EFL learners were conveniently selected based on their scores on Oxford Placement Test. The speaking module of Preliminary English Test (PET) was used to measure the participants' speaking accuracy and fluency before and after the intervention. The results of the study indicated that both groups made a significant improvement after the course. Nevertheless, the asynchronous digital storytelling group outperformed the synchronous one after the intervention.

Authors: NASTASE Carmen , MUSCAL Daniela
Published: October 2021

The circular economy is an alternative economic model to the current linear economy. The main feature of the circular economy is to preserve the value of resources. The circular economy generates indisputable environmental benefits, social benefits and added value for companies, aspects necessary to guarantee resource sustainability and ecological diversity in a globalized, complex and often unpredictable global context. Despite the fact that tourism plays an important role in the economic development of tourist regions and in the integration of these economies in the process of globalization, it puts great pressure on natural resources and the environment. Tourism activity generates environmental impacts and economic impacts. The aim of this paper is to analyze the future tendencies of tourism, how the circular economy can create value for the tourism sector and the steps to be followed to create a sustainable model. The society we live in has exhausted the resources needed to meet the future needs of an increasingly affected planet. Tourism is a sector sensitive environmentally, because while exploiting resources for its economic development, compromising their future growth. For this reason, it is very important to adopt tourism practices that promote respect for the planet - Earth, because we destroy our home and today we are already living the consequences and the circular economy is born of the real need to save the planet we live on. Change is the key to a sustainable model. Today there are endless opportunities, we need to rethink our current system and open up to new perspectives through innovation and creativity.

Apuntes sobre Charly García
Authors: Pujol Sergio
Published: October 2021

El presente artículo examina el saber musical de Charly García como diferencial sociocultural en el contexto del rock argentino. Desde su irrupción en 1972 con el dúo Sui Generis hasta su coronación como ícono pop en los años 80, el músico se valió de su formación musical entendida como capital simbólico para legitimarse como artista popular y, al mismo tiempo, legitimar el rock argentino. La medida de su triunfo está dada por su trascendencia más allá de la cultura rock: imposible pensar la música argentina de los últimos cincuenta años sin atender la obra de Charly García. Nos proponemos aquí reflexionar no tanto sobre el “contenido” musical del creador de “No bombardeen Buenos Aires” como sobre los recursos de los que supo valerse para ser reconocido en un género popular que, en los primeros tramos de su historia, fue objeto de destrato y desdén por parte del campo cultural argentino.
Saberes y placeres femeninos en Retrato de la Lozana andaluza
Authors: Pavón María Cecilia
Published: October 2021

Retrato de la Lozana andaluza es un libro particular, una rara avis en la extensa cantidad de obras continuadoras de La Celestina. El Retrato fue publicado aproximadamente en 1530, en Venecia, pero fue concebida en el espacio fronterizo, tanto geográfico como ideológico, entre España y Roma. Su autor, Francisco Delicado compartió con Lozana el mismo destino de exilio y olvido hasta que Ferdinand Wolf en 1845 logró reencontrar autor y obra en una referencia. En esta obra desmesurada, hilarante, provocadora, de contenido obsceno y realización sumamente culta analizaremos cómo se construye y representa la identidad femenina alrededor del eje de la corporeidad y cómo se resignifican los rasgos de femineidad promulgados por la mentalidad patriarcal dominante del siglo XVI.

Published: October 2021

El propósito de este artículo es sistematizar los estudios críticos acerca del adiestramiento castrense en los personajes de La ciudad y los perros (1963). Para conseguirlo, se confrontará con la hermenéutica de Gadamer, orientada a la propalación de estrategias heurísticas y taxonomías que consoliden el corpus de la novela cotejada. Así, se reconocerá el efecto que cumplen las variantes extrínsecas de la lectura, tales como las jerarquías y las percepciones idóneas y erróneas de la educación del Colegio Militar Leoncio Prado. Por ello, la adecuación de este contenido permitirá una mayor dilucidación del tema cuestionado con su respectivo soporte crítico.

The Coronavirus disease 2019 (COVID-19) pandemic has thoroughly and deeply affected the provision of healthcare services worldwide. In order to limit the in-hospital infections and to redistribute the healthcare professionals, cardiac percutaneous intervention in Pediatric and Adult Congenital Heart Disease (ACHD) patients were limited to urgent or emergency ones. The aim of this article is to describe the impact of the COVID-19 pandemic on Pediatric and ACHD cath laboratory activity during the so-called ‘hard lockdown’ in Italy.

Eleven out of 12 Italian institutions with a dedicated Invasive Cardiology Unit in Congenital Heart Disease actively participated in the survey. The interventional cardiology activity was reduced by more than 50% in 6 out of 11 centers. Adolescent and ACHD patients suffered the highest rate of reduction. There was an evident discrepancy in the management of the hard lockdown, irrespective of the number of COVID-19 positive cases registered, with a higher reduction in Southern Italy compared with the most affected regions (Lombardy, Piedmont, Veneto and Emilia Romagna).

Although the pandemic was brilliantly addressed in most cases, we recognize the necessity for planning new, and hopefully homogeneous, strategies in order to be prepared for an upcoming new outbreak.

Subject. The article considers the use of digital platforms and ecosystems, the analysis of their nature from the standpoint of marketing and its functions transformation.
Objectives. We investigate possibilities of designing platforms and ecosystems based on existing information products as applied to the branches of the information economy.
Methods. The study draws on the systems approach as a general methodological principle for solving interrelated modeling problems.
Results. Despite the established opinion that external platforms are more competitive due to the increased network effect and openness, internal digital platforms (implemented within individual companies) and ecosystems they generate can become a significant factor for successful functioning of small and medium-sized businesses. At the same time, a design, where an industry ecosystem is formed on the basis of a leading platform, can successfully exist. The paper presents examples of such solutions for Russian information companies.
Conclusions. Building a platform on the basis of a dedicated core in the form of existing information product, with the interests of its owner coinciding with the challenges of the relevant market, ensures long-term competitiveness of platform solutions in various formats of specific architecture.

Dalam bersaing saat ini, perusahaan yang memproduksi durable product seperti produk elektronik, produk mesin atau alat berat umumnya dijual dengan pemberian garansi sebagai salah satu bentuk layanan purna jual. Garansi merupakan suatu perjanjian kontrak yang diberikan oleh produsen atau retailer terhadap pelanggan yang membeli produk tersebut berupa penggantian atau perbaikan apabila mengalami kerusakan selama masa periode garansi. Produk dengan masa garansi yang lama bisa dijadikan tolak ukur oleh konsumen bahwa produk tersebut memiliki kualitas yang baik. Pemberian garansi menimbulkan tambahan biaya bagi produsen maupun retailer, yang disebut dengan biaya garansi. Pada penelitian ini akan mengukur dampak terhadap penerapan strategi perpanjangan garansi yang diberikan oleh dua retailer yang berbeda dengan produsen yang sama selaku pemberi garansi dasar kepada pelanggan, dengan metode pengembangan model strategi garansi Bian dan Esmaili. Strategi perpanjangan garansi yang dilakukan produsen berupa menawarkan garansi dasar kepada pelanggan dengan jenis garansi Free Replacement Warranty. Untuk kedua retailer memberikan penawaran pilihan perpanjangan garansi kepada pelanggan; yang pertama memberikan perpanjangan garansi dengan jenis garansi Free Repairment Warranty, dengan biaya garansi dibundel dengan harga produk; kedua tidak memberikan perpanjangan garansi. Hasil pengukuran menunjukkan, strategi dengan perpanjangan garansi oleh retailer memberikan profit supply chain dan profit bagi produsen yang lebih besar daripada yang tidak memberikan perpanjangan garansi.
