Abstract
Coronavirus disease-2019 (COVID-19) in Indonesia began to appear on March 2, 2020 and led to a number of fatalities. Spatial analysis is important to study the spatio-temporal trend of COVID-19 cases and fatalities to get a better understanding of the spread as well as to mitigate it. However, such a comprehensive study at national level is not to be seen in Indonesia with limited health infrastructure. This study aims to analyse the spatio-temporal distribution and clusters of COVID-19 in Indonesia for a year period. COVID-19 cases, as well as the fatalities as a consequence of this disease, were collected from the government through publicly shared data. A geographic information system (GIS) was used to manage and analyse the data on demographics, cases, and fatalities. The case fatality rate (CFR) was produced based on the number of cases and deaths per province weekly. The spatio-temporal data of both cases and fatalities were generated from the data. Finally, K-means clustering was employed to classify the cluster of Indonesia based on the proportion of vulnerable age groups, cases, and CFR. The results show that most of the provinces in Indonesia are affected by COVID-19, but the fatalities are not distributed evenly throughout the country. Based on the K-means clustering, two provinces are classified as moderate, namely the Province of East Kalimantan and North Kalimantan. The Province of Jakarta is classified as high, because the vulnerable age group there is highly correlated with the number of cases and deaths.

Abstract
The study of the transformation of natural complexes in areas with a developed infrastructure for oil subsurface use is a prerequisite condition for solving the environmental problems of oil-producing regions. Located in the territory of the Atyrau Region in Western Kazakhstan, the Tengiz oil field is one of the largest oil fields in the world. The field has been under intensive development for more than 40 years and is characterised by a large volume of anthropogenic load, which contributes to a significant transformation of the landscape complex. The purpose of this study is to investigate the dynamics of landscape changes in the territory of the Tengiz field and to assess its ecological condition. Based on the materials from many years of research, the features of the Tengiz field and the main technogenic sources affecting the landscape complex were identified. Several quantitative indicators characterising the anthropogenic load were calculated based on satellite images. On the basis of Landsat – 5 TM, 7 ETM+ and 8 OLI and Sentinel-2A (S2A) data, the vegetation index of land cover was calculated using normalised difference vegetation index (NDVI), demonstrating the dynamics of landscape changes in the period from 1990 to 2020. The obtained results show that the areas of some landscape components continue to deteriorate. For example, the area of open soil in 2020 decreased due to the withdrawal of these areas for industrial facilities, which increased by 2.2 times by 2020 due to intensive field development. This study demonstrates the importance of monitoring and studying desert landscape complexes under active anthropogenic impact to ensure the sustainable development of territories.

Hacia un modelo predictivo para la segmentación prosódica del discurso oral coloquial: MESTEL (Modelo Estadístico para la Selección de Términos Entonativos Ligados)
Authors: Cabedo Nebot Adrián 
Published: June 2022

En la Lingüística tradicional, la prosodia ha sido poco considerada para identificar unidades operativas de análisis. Habitualmente, la segmentación inicial se basa en delimitaciones lingüísticas, basadas en un conocimiento previo del investigador; a partir de ellas, se analiza la influencia del nivel prosódico. Nuestra propuesta es que esa secuenciación empiece en lo prosódico (en su nivel acústico, más concretamente) y, a posteriori, se complete con otros niveles. Así pues, se pretende cambiar la perspectiva tradicional.
Además, en este artículo se propone un modelo de segmentación (semi)automática del discurso espontáneo oral. A partir del análisis de diferentes grupos entonativos, se presenta una fórmula probabilística (MESTEL) que calcula las probabilidades de que determinados segmentos del continuum oral puedan convertirse en fronteras de grupos entonativos.
Actos truncados estratégicos: Aspecto formal. Hacia el reconocimiento de sus tipos
Authors: Pose  Furest Francisca 
Published: June 2022

Aislar las unidades que componen los actos truncados estratégicos resulta una tarea complicada, pero ineludible para afrontar su estudio. Cada registro necesita unidades propias de análisis y en este trabajo presentamos una propuesta de las unidades que componen los actos truncados estratégicos en el género discursivo entrevista semidirigida (corpus PRESEEA-GRANADA). Partiendo de la posibilidad de que el segmento o acto truncado pueda convertirse en intervención, constatamos que el corte sintáctico puede producirse en el interior de un acto –truncamiento interno– o entre actos truncamiento externo–. Por otro lado, desde el punto de vista de la información, advertimos que los truncamientos pueden ser progresivos o regresivos, y en función de esto presentarán una forma u otra.

The authors present their experience in applying quantum electronic devices in patients undergoing lower limb amputations.Object. To develop a technique for potentiating the traditional multimodal anesthesia by optoelectronic devices with wavelength 650 nm (red range) and 470 nm (blue range) (manufactured in Russia) in amputation of lower extremities.Material and methods. Multimodal anesthesia with quantum electronic devices was performed in 48 patients (11 women and 37 men) aged 68–89 and having comorbidities. In the main group, for contact LED irradiation portable semiconductor LED device AFS к-630/670 emitting in red range with wavelength 650 ± 20 nm and portable AFS device emitting in blue range with wavelength 470 ± 10 nm and power 30 mW at the end of surgery were used. The above mentioned devices were made in the form of bracelets for non-invasive and non-contact application in the multimodal anesthesia during amputations of lower extremities. In the comparison group, multimodal anesthesia was not potentiated by contact LED irradiation.Results. The discussed Russian bracelets emitting in red and blue bands of the spectrum during amputation of lower extremities promoted the decrease of narcotic dosage (Fentanyl) during general multimodal anesthesia. In the main group, cardiac index increased at the end of surgery, and the total peripheral vascular resistance decreased if to compare to baseline values. In the comparison group, cardiac index increased somewhat less if to compare to baseline values, and the total peripheral vascular resistance decreased somewhat less if to compare to baseline values.Conclusion. The discussed bracelets emitting in red range (650 nm) which were applied during surgical interventions for the amputation of lower extremities and bracelets emitting in blue range (470 nm) which were applied at the end of surgery reduce the dose of narcotic preparations (Fentanyl) as well as stabilize hemodynamic parameters during surgery. Besides, in the immediate postoperative period, patients who survived amputation of lower extremities and in who the abovementioned bracelets were used do not require additional narcotic painkillers after amputation.

Background:
Neuroendocrine tumors (NETs) are uncommon neoplasms arising from neuroendocrine cells and are rarely associated with intracranial metastases.

Case Description:
We discuss the case of a 74-year-old woman with a right CPA tumor. She had a history of retroperitoneal NET, but was diagnosed with vestibular schwannoma due to a right-sided hearing loss and a right CPA tumor along the VII and VIII nerves. After a 3-year follow-up, she presented with repetitive vomiting, a 1-month history of gait instability, and a 3-month history of general fatigue. Brain imaging revealed tumor growth and edematous changes in the right cerebellum. She underwent retrosigmoid craniotomy and partial resection. Histopathological examination revealed metastatic NET. She underwent stereotactic radiosurgery for residual lesion and, at 11 months of follow-up, the lesion was confirmed to have shrunk on magnetic resonance imaging (MRI).

Conclusion:
This is the first case to report the natural course of cerebellopontine metastasis of a NET. The differential diagnosis of CPA tumors is diverse, and, in our case, we suspected a vestibular schwannoma because of the typical symptoms and imaging features. However, the tumor grew relatively faster than expected and showed intratumoral hemorrhage during the 3-year follow-up. Therefore, in patients with a history of a NET, a careful follow-up is advisable even for lesions highly suspected to be another benign tumor on MRI. Careful follow-up imaging and appropriate treatment strategies were useful to manage the brain metastasis. Although NETs metastasizing to the CPA are extremely rare, this possibility should be considered when patients with NETs have intracranial lesions.

Background:
Symptomatic common carotid artery (CCA) occlusion is rare and its treatment remains unestablished. Although cases of subclavian-to-carotid bypass have been reported, very few cases of carotid-tocarotid crossover bypass have been reported, despite its advantages. We report a case of Riles type 1A symptomatic CCA occlusion after aortic arch replacement that was treated with carotid-to-carotid crossover bypass with favorable outcomes.

Case Description:
A 65-year-old woman with a history of hypertension, hyperlipidemia, diabetes, and total arch replacement for thoracic aortic aneurysm was admitted to our hospital with a complaint of the right hemiparesis and motor aphasia. Head magnetic resonance imaging revealed a fresh infarction in the left cerebral hemisphere. Cervical computed tomography (CT) angiography revealed left CCA occlusion. Thoracic CT angiography showed severe stenosis of the left subclavian artery. SPECT showed a general decrease in blood flow in the left cerebral hemisphere. We performed a carotid-to-carotid crossover bypass with a synthetic graft that was passed through the subcutaneous tunnel. First, the right carotid artery-synthetic graft end-to-side anastomosis was performed. Subsequently, we performed synthetic graft-left CCA end-to-side anastomosis. The postoperative course was uneventful. Cervical computed tomography angiography showed perfect patency of the crossover bypass. The patient recovered almost completely and was independently performing daily activities.

Conclusion:
Carotid-to-carotid crossover bypass is a durable treatment for symptomatic CCA occlusion. Further studies are needed to compare its outcomes with those of other methods and to confirm our findings with larger sample size.

Published: June 2022

Одним из инструментов экологической политики в разных государствах является создание сети особо охраняемых природных территорий (ООПТ). Кроме сохранения биоразнообразия некоторые объекты ООПТ выполняют рекреационную функцию. Во многих странах система охраняемых территорий имеет два уровня: государственный и решиональный. В статье проводится сравнение системы ООПТ Австралии и России на примере двух территориально-административных образований этих государств: штата Виктория и Тверской области. Объектом анализа стали структура сети ООПТ и количество объектов. Затрагиваются вопросы организации и функционирования элементов сети ООПТ, предназначенных для туризма и рекреации. Выявлены положительные и отрицательные аспекты сформированной системы охраняемых природных объектов в обоих государствах. Сделаны предложения по совершенствованию сети ООПТ в Тверской области.
One of the tools of environmental policy in different states is the creation of a network of specially protected natural areas (PAs). In addition to preserving biodiversity, some objects of protected areas perform a recreational function. In many countries, the system of protected areas has two levels: state and resolute. The article compares the system of protected areas of Australia and Russia on the example of two territorial-administrative entities of these states: the state of Victoria and the Tver region. The object of the analysis was the structure of the network of protected areas and the number of objects. The issues of organization and functioning of elements of the network of protected areas intended for tourism and recreation are touched upon. Positive and negative aspects of the formed system of protected natural objects in both states are revealed. Proposals were made to improve the network of protected areas in the Tver region.

Existen algunos síntomas que pueden ser medidos muy rápidamente y pueden indicar un caso potencial de COVID-19 y ser aislado de manera oportuna, dos de ellos son: la temperatura y la oxigenación, este último bien documentado en la literatura y se refiere al porcentaje de oxígeno en la sangre, se mide mediante el SpO2 por medio de un oxímetro, este dispositivo es de bajo costo y sencillo de utilizar. De lo más implementado en los filtros de entrada para algún sitio es la toma de temperatura, que en la mayoría de los casos una persona quien realiza la medición, algu-nos otros emplean un sistema de reconocimiento mediante una pantalla que despliega la tempe-ratura, otro ejemplo, pero de mucho mayor costo es la incorporación de un Robot inteligente capaz de identificar posibles casos COVID.
Este trabajo propone el desarrollo de un dispositivo que incorpora la medición de temperatura y oxígeno para la detección de posibles casos COVID-19, como apoyo y filtro en una entrada de personas, así como una aplicación web para el seguimiento de la actividad de la COVID-19 en la comunidad Lasallista. La solución presenta dos etapas de desarrollo, en la primera se diseña un dispositivo que incorpora la medición de temperatura y oxígeno y la segunda etapa, plantea el desarrollo de una aplicación web para el seguimiento de la actividad de la enfermedad en la co-munidad Lasallista, la cual recopila datos relevantes del ingresante en alguno de los campus La-sallistas, para apoyar el seguimiento y/o detección de un caso COVID.El impacto de esta propuesta está dirigido en la prevención de brotes dentro de la institución salvaguardando la salud de la mayor cantidad de personas posibles, en caso de tener una persona asintomática dar un mejor seguimiento por medio del registro de ingreso en la aplicación web.
Este trabajo logra construir una herramienta que incorpora de manera independiente un sensor de temperatura y un oxímetro para que se pueda hacer una medición de dos variables que permi-ten indicar un posible caso COVID-19 sin necesidad de tener a una persona realizando dicha me-dición, además de implementar una aplicación web con los datos necesarios para dar seguimiento cuando se presenta un caso positivo de COVID-19 dentro de la comunidad Lasallista.
