A desconstrução de Derrida e a natureza que logo somos
Authors:   , Toledo Túlio
Published: October 2022

Esta dissertação se desenvolve no intuito de evidenciar a crise do Ser do antropoceno através de uma aproximação entre o pensamento do filósofo Jacques Derrida e outros pensadores que se permitiram um olhar diferenciado perante o mundo natural. Com sua proposta da desconstrução, Derrida traça toda uma impossibilidade de uma origem rígida para o conhecimento ao contestar os limites do pensamento centralizado causador de uma extrema ruptura entre o Ser da individualidade da presença e toda a potência heterogênea das incontáveis alteridades. Criticar todo condicionamento oriundo de certo logocentrismo é possibilitar a abertura das práticas de sentido para uma nova atuação da era geológica dos humanos e seu relacionamento com o outro, com o animot e com a multiplicidade de viventes. Deste modo, a desconstrução e o rastro da Natureza adentram também na problemática da educação e da ciência que precisariam reorientar seus próprios paradigmas metodológicos a fim de propiciar uma ressignificação dos sentidos humanos perante sua própria atuação no mundo. O estudo tem como objetivo compreender a importância de libertar o conhecimento de toda uma centralidade idealizada, condicionante e condicionadora, através de certos conceitos fundamentais como a différance e o deserto que evidenciariam a característica imanente do pensamento de pertencimento a um perpétuo fluxo de movimento sem uma origem limitada. A desconstrução aqui aparece como um mergulho profundo em busca de uma alteridade totalmente outra, uma alteridade que se mistura na interdependência da Natureza. O procedimento adotado é especificamente uma pesquisa bibliográfica de reflexão filosófica e poética, mediante uma análise das crises sociais e ambientais e uma busca de reorientação da práxis humana diante de sua morada Terra. A desconstrução invoca a responsabilidade de um repensar do agir humano que possibilite e garanta um porvir mais consciente da própria humanidade.

Key Points

Baseline eGFR does not affect the effects of supplementation with vitamin D3 on the incidence of cardiovascular events or invasive cancer.

Vitamin D3 supplementation results in a greater reduction in serum parathyroid hormone concentration in those with lower versus higher eGFR.

Background

Reduced 25-hydroxyvitamin D (25[OH]D) metabolism and secondary hyperparathyroidism are common with lower estimated glomerular filtration rate (eGFR) and may contribute to cardiovascular disease and cancer risk.

Methods

We assessed for heterogeneity by baseline eGFR of the effects of vitamin D3 on cardiovascular and cancer outcomes in the Vitamin D and Omega-3 Trial (VITAL). Participants were randomized to 2000 IU vitamin D3 and/or 1 g Ω-3 fatty acids daily using a placebo-controlled, two-by-two factorial design (5.3 years follow-up). Primary study end points were incident major cardiovascular events and invasive cancer. Changes in serum 25(OH)D and parathyroid hormone (PTH) were examined.

Results

Baseline eGFR was available for 15,917 participants. Participants’ mean age was 68 years, and 51% were women. Vitamin D3 resulted in higher serum 25(OH)D compared with placebo (difference in change 12.5 ng/ml; 95% CI, 12 to 13.1 ng/ml), without heterogeneity by eGFR (P interaction, continuous eGFR=0.2). Difference in change in PTH between vitamin D3 and placebo was larger with lower eGFR (P interaction=0.05): –6.9 (95% CI, –10.5 to –3.4), –5.8 (95% CI, –8.3 to –3.4), –4 (95% CI, –5.9 to –2.2), and –3.8 (95% CI, –5.6 to –2) pg/ml for eGFR <60, 60–74, 75–89, and ≥90 ml/min per 1.73 m2, respectively. Effects of vitamin D3 supplementation on cardiovascular events (P interaction=0.61) and cancer (P interaction=0.89) did not differ by eGFR: HR=1.14 (95% CI, 0.73 to 1.79), HR=1.06 (95% CI, 0.75 to 1.5), HR=0.92 (95% CI, 0.67 to 1.25), and HR=0.92 (95% CI, 0.66 to 1.27) across eGFR categories for cardiovascular events and HR=1.63 (95% CI, 1.03 to 2.58), HR=0.85 (95% CI, 0.64 to 1.11), HR=0.84 (95% CI, 0.68 to 1.03), and 1.11 (95% CI, 0.92 to 1.35) for cancer, respectively.

Conclusions

We observed no significant heterogeneity by baseline eGFR in the effects of vitamin D3 supplementation versus placebo on cardiovascular or cancer outcomes, despite effects on 25(OH)D and PTH concentrations.
Actigraphy-Based Assessment of Sleep Parameters in Intensive Care Unit Patients Receiving Respiratory Support Therapy
Authors: Kang Jiyeon , Kwon Yongbin
Published: October 2022

Purpose : This study aimed to investigate sleep parameters and to identify differences according to respiratory support therapy, sedation, and pain medication in intensive care unit (ICU) patients.Methods : In this observational study, sleep parameters were measured using actigraphy. We observed 45 sleep events in 30 ICU patients receiving respiratory support therapy. We measured the sleep parameters, time, efficiency, and wakefulness after sleep onset (WASO). The differences in sleep parameters according to the respiratory support therapy were analyzed using the Mann-Whitney U test.Results : The average daily sleep time of the participants was 776.66±276.71 minutes, of which more than 60% accounted for daytime sleep. During night sleep, the duration of WASO was 156.93±107.91 minutes, and the frequency of WASO was 26.02±25.82 times. The high flow nasal cannula (HFNC) group had a significantly shorter night sleep time (χ2=7.86, p =.049), a greater number of WASO (χ2=5.69, p =.128), and a longer WASO duration (χ2=8.75, p =.033) than groups of other respiratory therapies.Conclusion : ICU patients on respiratory support therapy experienced sleep disturbances such as disrupted circadian rhythm and sleep fragmentation. Among respiratory support regimens, HFNC was associated with poor sleep parameters, which appears to be associated with the insufficient use of analgesics. The results of this study warrant the development of interventions that can improve sleep in ICU patients receiving respiratory support, including HFNC.

Authors: Moon Sun Jung , Jang Haena
Published: October 2022

Purpose : This study aimed to identify the factors influencing the professional quality of life of intensive care unit (ICU) nurses working in university hospitals.Methods : A survey was conducted on 171 ICU nurses in university hospitals in B City, South Korea. This study used the Professional Quality of Life instrument, which consists of three subscales, namely, compassion satisfaction, burnout, and secondary traumatic stress. Data were analyzed using stepwise multiple regression analysis.Results : Compassion satisfaction was influenced by resilience, ICU job satisfaction, and innovation-oriented culture, and these variables explained 37.1% of the variance in compassion satisfaction. Burnout was influenced by resilience, a hierarchy-oriented culture, and ICU job satisfaction, and these variables explained 42.9% of the variance in burnout. Secondary traumatic stress was influenced by a task-oriented culture and resilience, and these variables explained 12.5% of the variance in secondary traumatic stress.Conclusion : These findings suggest the importance of improving resilience and job satisfaction to enhance the professional quality of life in ICU nurses. Moreover, creating an innovation-oriented culture rather than a hierarchical and task-oriented culture can effectively improve the professional quality of life of ICU nurses.

Цель исследования. Определение перечня состояний, связанных со свертыванием крови и способствующих возникновению рецидива инфаркта мозга у пациентов детского возраста.Материалы и методы. Проведен ретроспективный анализ причин заболевания и рецидива ишемического инсульта (ИИ) у 55 детей, обратившихся в стационар по поводу ишемического инсульта с июля 2016 по май 2022 г. Возраст детей – от 1 до 17 лет, мальчиков – 32, девочек – 23.Результаты. Анализ исходов ишемического инсульта у обследованных детей показал, что каждое из проанализированных гематологических состояний потенциально может стать причиной повторных ишемических атак с развитием неврологических нарушений. Кумулятивная частота рецидива в остром периоде ИИ составила (7,3±3,5)%. Рецидив ИИ в остром периоде заболевания был тесно связан с назначением противотромботических препаратов (G=0,99; p=0,02), доза которых была недостаточна. Кумулятивная частота рецидива ИИ на этапах восстановления составила (20,9±8,3)% и была связана в равной мере как с отсутствием профилактического применения противотромботических средств (G= –0,33; p=0,25), так и с гематологической причиной (G=0,33; p=0,21) заболевания.Заключение. Полученные результаты указывают на необходимость использования противотромботических лекарственных средств у всех пациентов с ишемическим инсультом. Обязательны контроль за достижением фармакологического эффекта и коррекция дозы антикоагулянта (антиагреганта) с учетом клинической ситуации.

Purpose. To determine the list of conditions associated with blood clotting and contributing to the recurrence of cerebral infarction in pediatric patients.Materials and methods. A retrospective analysis of the causes of the disease and recurrence of ischemic (IS) stroke was carried out in 55 children who applied to the hospital for ischemic stroke from July 2016 to May 2022. The age of children is from 1 to 17 years, boys – 32, girls – 23.Results. An analysis of the outcomes of ischemic stroke in the examined children showed that each of the analyzed hematological conditions could potentially cause recurrent ischemic attacks with the development of neurological disorders. The cumulative recurrence rate in the acute period of IS was (7.3±3.5)%. The recurrence of IS in the acute period of the disease was closely associated with the prescription of antithrombotic drugs (G=0.99; p=0.02), the dose of which was insufficient. The cumulative recurrence rate of IS at the stages of prophylactic use of antithrombotic agents was (20.9±8.3)% and was equally associated with both the lack of prophylactic use of antithrombotic agents (G= –0.33; p=0.25) and hematological cause (G= 0.33; p=0.21) of the disease.Conclusion. The results obtained indicate the need for the use of antithrombotic drugs in all patients with ischemic stroke. It is obligatory to control the achievement of the pharmacological effect and adjust the dose of the anticoagulant (antiplatelet) taking into account the clinical situation.

В статье представлен анализ поздних осложнений химиолучевой терапии лимфомы Ходжкина (ЛХ) у 95 пациентов 0–18 лет в Республике Беларусь. Пациенты получали программную терапию в рамках протокола DAL-HD-90(m). Выявлено, что в основном осложнения развивались в результате лучевого воздействия на органы и ткани. Риск отдаленных последствий у пациентов с ЛХ увеличивается с увеличением суммарных доз облучения. Полученные данные подтверждают необходимость снижения объемов лечения и уточнения показаний к лучевой терапии с учетом прогностических факторов, внедрения новых методик лучевой терапии и использования новых схем лечения пациентов детского возраста с ЛХ.

The analysis of late complications of chemoradiotherapy of Hodgkin’s lymphoma (HL) in 95 pediatric patients of the Republic of Belarus is presented. Patients 0 to 18 years old with LH received program therapy under the DAL-HD-90(m) protocol. It was revealed that complications mainly developed as a result of radiation exposure to organs and tissues. The risk of the complications increased with an increase in total radiation doses. The data obtained confirm the need to reduce the doses and indications for the use of radiation therapy in HL, taking into account prognostic factors, the introduction of new methods of radiation therapy and the use of new treatment regimens for children with HL.

По результатам динамического наблюдения и лабораторной и инструментальной оценки показателей здоровья 113 регулярных доноров крови и компонентов крови выявлены изменения гематологических и биохимических показателей. Согласно данным исследования, до 50% доноров крови и ее компонентов имеют дефицит железа. Установлено, что у доноров крови статистически значимо более низкие показатели, характеризующие обмен железа, чем у доноров компонентов крови. Данные изменения также имеют особенности в зависимости от пола. У доноров компонентов крови статистически значимо более низкие показатели содержания белка и более высокие показатели содержания лейкоцитов и кальция, чем у доноров цельной крови. Не установлено клинически значимых изменений показателей системы гемостаза, электрокардиографии. Сделан вывод о необходимости более расширенного и частого по сравнению с действующим скрининга на дефицит железа, белка и, с учетом полученных результатов, назначения в рамках междонационного периода медикаментозной коррекции и определенного режима питания, изменения видов и интервалов донаций.

Summary to the results of dynamic monitoring, laboratory and instrumental assessment of health indicators of 113 regular blood donors and blood components, changes in hematological and biochemical parameters were revealed. Data have been obtained characterizing iron deficiency in up to 50% of blood donors and its components. It has been established that whole blood donors have statistically significantly lower rates characterizing iron metabolism than blood component donors. These changes also have features depending on gender. Blood component donors had statistically significantly lower protein levels and higher leukocyte and calcium levels than whole blood donors. There were no clinically significant changes in the parameters of the hemostasis system, electrocardiography. It was concluded that there is a need for a more extended and frequent screening for iron and protein deficiency compared to the current one and, taking into account the results obtained, within the inter donation period of prescribing drug correction and a certain diet, changing the types and intervals of donations.

Цель исследования - сравнительный анализ субъективных оценок и аудиологических показателей у пациентов сурдологического профиля, полученных до и после прохождения курса транскраниальной электростимуляции (ТЭС). В группу обследования вошли 99 пациентов 20-85 лет (45 мужчин и 54 женщины) с хронической одно- (16%) и двусторонней (76%) сенсоневральной тугоухостью (СНТ). Группа молодого и среднего возраста (20-59 лет) составила 37 человек, пожилого (60-74 лет) - 48, старческого (75-90 лет) - 14. Обследование включало сбор анамнеза, ЛОР-осмотр, тональную пороговую аудиометрию, импедансометрию, анкетирование. Все пациенты прошли курс из 10 процедур ТЭС с применением прибора «Трансаир-7». Данные свидетельствовали об улучшении субъективных оценок в отношении слухового восприятия у 54% пациентов, разборчивости речи - у 53%, ушного шума - у 24%, общего самочувствия - у 36%. Распределение порогов слуха в области речевых частот до и после курса также оказалось достоверно различным ( p <0,01). При этом были выявлены гендерные и возрастные особенности влияния ТЭС на показатели слуха и общего самочувствия, наиболее выраженные у пациентов старческого возраста, продемонстрировавших минимальную положительную динамику. В целом, с учетом возрастных ограничений, результаты подтверждают целесообразность применения ТЭС при хронической СНТ даже вне режима комбинированной (с аудионагрузкой) стимуляции.

The aim of the study was a comparative analysis of subjective assessments and audiological parameters of patients with hearing loss obtained before and after the course of transcranial electrical stimulation (TES). The study group included 99 patients (45 men and 54 women) with chronic mono- (16%) and bilateral (76%) sensorineural hearing loss (SNHL) aged 20 to 85 years. Groups of young and middle age (20-59 years old) amounted to 37 people; elderly (60-74 years old) - 48 and senile (75-90 years old) - 14 people. The observation included: anamnesis, ENT survey, tone threshold audiometry, impedancemetry, and questioning. All patients underwent a course of 10 TES procedures using the «Transair-7» device. The data indicated an improvement in subjective assessments regarding auditory perception in 54%, speech intelligibility in 53%, tinnitus in 24% and general well-being in 36% of patients in the study group. The distribution of hearing thresholds in the region of speech frequencies before and after the course also turned out to be significantly different (p<0,01). At the same time, gender and age-specific features of the effect of TES on hearing and general well-being were revealed, the most pronounced in senile patients who showed minimal positive dynamics. In general, taking into account age restrictions, the results confirm the feasibility of using TES in SNHL, even outside the combined (with audio loading) stimulation.

Published: October 2022

При неэффективности консервативной терапии хронического риносинусита во всех возрастных группах больных в настоящее время часто прибегают к функциональным риносинусохирургическим эндоскопическим вмешательствам. Имеются сообщения об использовании бета-адреноблокаторов для снижения операционной кровоточивости, однако недостаточно изучена возможность их внутривенного применения у пациентов старшей возрастной группы. Цель работы - оценка эффективности внутривенного применения метопролола для снижения интраоперационного кровотечения (ИК) при риносинусохирургических вмешательствах в условиях общей анестезии у пациентов пожилого и старческого возраста. ИК оценивали по шкале Fromme-Boezaart Score на разных этапах операции с 10-й по 60-ю минуту в двух группах больных - без применения метопролола (БМ) и с использованием метопролола (М). Выявлено, что на 30-й минуте операции ИК была значимо ниже в группе М. Многофакторный анализ показателей гемодинамики выявил прямую связь показателей ЧСС с развитием кровоточивости. В группе БМ вероятность значительной кровоточивости была выше в 8,6 раза. Показано, что внутривенное интраоперационное применение метопролола позволяет снизить интенсивность локальной кровоточивости при эндоскопических риносинусохирургических вмешательствах.

With the ineffectiveness of conservative therapy of chronic rhinosinusitis in all age groups of patients, functional rhinosinusosurgical endoscopic interventions are now often used to do. The minimal bleeding is a necessary condition for their realization. There are reports of the use of beta-blockers for reducing surgical bleeding, but the possibility of their intravenous use in older patients has not been sufficiently studied. The aim of the work was to evaluate the effectiveness of intravenous metoprolol to reduce the bleeding intensity (BI) during rhinosinusosurgical interventions under general anesthesia in elderly and senile patients. The BI was assessed on the Fromme-Boezaart Score scale at different stages of the operation from the 10th to the 60th minute in two groups of patients: without (WM) and using metoprolol (M). It was shown that at the 30th minute of the operation BI was significantly lower in M group. Multivariate analysis of hemodynamic parameters demonstrated a direct relationship between heart rate (HR) and the development of bleeding. In the WM group, the probability of significant bleeding was 8,6 times higher. It has been shown that intraoperative intravenous use of metoprolol reduces the intensity of local bleeding during endoscopic rhinosinusosurgical operations.
New approaches to the treatment of acute peritonitis

Published: October 2022

The high prevalence of acute peritonitis, its unpredictable course, and the rapid development of systemic dysfunctions necessitate further study of the disease. It is relevant to use the principle of personalized medicine, which is based on the selection of diagnostic, therapeutic and preventive means taking into account the patient's genetic, physiological, biochemical and other characteristics. The paper presents data on the diagnosis and treatment of acute peritonitis in 246 patients who, in addition to standard clinical, biochemical, immunoenzymatic and genetic studies, were conducted to determine the role of proinflammatory cytokines (IL1β) in the pathogenesis of the inflammatory process and the development of its complications. The dependence of the manifestations of inflammation and it’s spread on the concentration of IL1β in the blood and variants of the IL1β gene (‒511C/T), which regulates its secretion, is shown. The processes of peroxidic oxidation, antioxidant protection, unlimited proteolysis, fibrinolytic activity in the implementation of systemic reactions in peritonitis were studied, and their individual variability was shown. On the basis of the conducted research, the stages of surgical interventions, drug treatment schemes and proposed methods of prevention of various complications have been improved. This approach to diagnosis, forecasting the course of acute peritonitis, and the choice of treatment tactics is personalized and provides an opportunity to significantly improve the results of treatment of such patients and reduce mortality.

Investigation of Olivine Mineral's Use in Ceramic Glazes and Applications
Authors: TURAN Beyza , ACARTÜRK Buket
Published: October 2022

Olivine, which has been used in industry since the 1930s, is a mineral type that takes its name from the Olive color. Olivine has gained increasing importance in the industry over time and has gained an important place as the Olivine industry all over the world today. The chemical compound of commercial Olivine contains 45-50% Magnesium Oxide, 40-43% Silicon Dioxide, 8% Iron Oxide and 1-2% glow loss. The fact that the olivine mineral is environmentally friendly, has a significant potential in terms of reserves in Turkey and has not been used in ceramic glazes before are important parts of the study. In this study, it is aimed to investigate the usability of olivine mineral in glaze making. In the research, alkaline, alkaline-boron and boron glazes consisting of basic raw materials such as albite, orthoclase, petalite, calcined borax, colemanite and boric acid were prepared using the experimental method. Olivine is used in glaze recipes by adding 10-50-80%. The glaze mixtures prepared were applied to the test tablets shaped with ESC 1 Code white tile casting clay and fired at 1150°C. As a result of the study, faultless glazes were made with a maximum of 50% Olivine contribution. The glazes obtained from the test results were evaluated according to surface properties such as glossy, matte, crackle, and the study was supported by presenting them in the text.

Authors: ÖZBAĞ Fatih , MODANLI Mahmut
Published: October 2022

Fractional differential equations are useful for modelling mathematical issues in fields including engineering, physics, and biology. In this article, approximate solutions of an initial boundary value problem for fractional pseudo hyperbolic differential equations are investigated using the finite difference method. First, a first-order finite difference scheme is created for the initial boundary value problem. Then, stability analysis was performed for this finite difference scheme. In order to support the theoretical results obtained, error values were calculated for precise and approximate solutions in different fractional order derivatives of a sample problem. Some numerical simulations are also given to show the effectiveness of the applied solution method.

¿Es posible el desarrollo de una ciudadanía intercultural sin comunicación supranacional?
Authors:   , Di Bin María Verónica
Published: October 2022

Esta investigación ha estado motivada por el concepto desarrollado por Michael Byram (2008) sobre ciudadanía intercultural, y el análisis de sus axiomas y características (Byram et al., 2017). La manera en que estos axiomas son concebidos radica en la idea de individuos que actúan de manera conjunta, en donde la premisa es que las personas actúan de manera diferente como “ciudadanos interculturales” que como lo harían como “ciudadanos nacionales”. Uno de esos axiomas establece que “la experiencia intercultural se lleva a cabo cuando individuos de diferentes grupos sociales con diferentes culturas (valores, creencias y comportamientos) se encuentran” (Byram et al., 2017, p.xxvi); una característica es la creación de “una comunidad de acción y comunicación que es supranacional” (Ibid., p.xxv); y un criterio es que los estudiantes “crean y cooperan en grupos de varias nacionalidades” (Ibid., p.xxvi) utilizando la lengua extranjera que están aprendiendo. Pero, ¿qué sucede cuando esta comunicación supranacional no es posible o cuando los individuos que interactúan en esa comunicación no pertenecen a diferentes grupos sociales con diferentes culturas y lenguas nativas? Con el objetivo de investigar si la ciudadanía intercultural es posible pedagógicamente en aulas donde este axioma, esta característica y este criterio no son factibles, esta investigación describe un estudio de caso llevado a cabo en una clase de inglés como lengua extranjera en una escuela secundaria en Argentina que desafía, en parte, ese pensamiento nacionalista de una manera no identificada en la teoría. Este estudio abordó la temática “el mundo que deseamos” utilizando los objetivos de desarrollo sostenible propuestos por la Organización de las Naciones Unidas como base, prestando particular atención a cuestiones ambientales y sin que haya comunicación transnacional. Los resultados indican que el pensamiento internacionalista, en oposición al pensamiento nacionalista (Byram, 2018) se volvió central en este caso, ya que el resultado fue más importante que el posible proceso de participar en una comunicación supranacional identificada como uno de los axiomas de la teoría. Sobre esta base, sostengo que este estudio desafía la teoría y pedagogía de la ciudadanía intercultural en su forma actual y sugiero el enriquecimiento de ambas recurriendo a las nociones de internacionalismo, comunidades imaginadas y ciudadanía ecológica.

Las dermatosis autoinmunes se dividen en tres grupos: complejo pénfigo, enfermedades ampollares subepidérmicas autoinmunes y lupus. Como objetivo se establecieron bases clínicas, histopatológicas e inmunohistoquímicas para el diagnóstico. Se realizó un estudio retrospectivo (n=74) y prospectivo (n=19). Se consideraron las lesiones macroscópicas, las lesiones microscópicas y la aplicación de las técnicas de inmunohistoquimica, inmunofluorescencia y lectinhistoquímica. Se observaron diferencias significativas en el complejo pénfigo con relación a la localización (periorbital y pabellones auriculares), la raza y la presencia de pústulas y acantólisis. En el lupus se observó degeneración vacuolar de células basales y en las enfermedades ampollares separación dermoepidérmica. En la aplicación de la técnica de inmunohistoquímica se obtuvo un 77,03% de inmunomarcación. En el 21,05% de los casos estudiados se pudo, mediante esta técnica, complementar el diagnóstico histopatológico. Las enfermedades autoinmunes deben ser tenidas en cuenta en pacientes que presentan pústulas, vesículas, bullas y, más frecuentemente, costras, erosiones y úlceras en el dorso de la nariz, la zona periocular y los pabellones auriculares. La histopatología es útil en el diagnóstico de estas enfermedades y, en nuestro medio, sigue siendo la herramienta más utilizada para arribar a un diagnóstico definitivo.
“Vivir los libros”

En esta tesis se analizan los vínculos que establecen las juventudes con lo literario, especialmente con aquellos productos ligados a la industria masiva del entretenimiento. Para ello, el trabajo empírico se centró en dos comunidades lectoras: las y los aficionados de la saga Harry Potter que se nuclean en un club de fans, y quienes conforman la comunidad BBB de bloggers, booktubers y bookstagrammers: jóvenes que comparten experiencias lectoras a través de sus redes sociales. Se asume que estas personas tienen en común el hecho de ser lectoras y lectores transformados por lo literario, ya sea por la cantidad de libros leídos, pero, sobre todo, por el significativo vínculo que con la lectura entablan. Desde una perspectiva socioantropológica de la lectura que procuró captar las formas sensibles y emotivas que se despliegan en torno a lo literario y que a la vez fuera hospitalaria con los objetos que intervienen en la conformación de los vínculos, se relevaron experiencias empíricas de lecturas, afición y consumos culturales. Una operación que permitió, al mismo tiempo, mostrar cómo esto tiene correlatos en otras esferas vitales como la educativa, la laboral o la implicancia en causas de interés social y público, incluso cuando optan por relacionarse a partir de productos identificados con la industria cultural masiva. En términos metodológicos, esta perspectiva, atenta no solo al decir sino especialmente a los planos de performatividad y acción puestos en lo literario, supuso el despliegue de una mirada y una estrategia etnográfica que colocó en primer plano a las y los lectores, entendidos como interlocutoras/es. De esta forma, se buscó mostrar las continuidades entre esferas online y offline con la realización de trabajo de campo in situ en eventos considerados claves por mis interlocutoras/es, al mismo tiempo que se desplegaron técnicas de seguimiento y participación en las redes sociales en las que interactúan. La tarea se complementó con la realización de entrevistas etnográficas semi-estructuradas y biográficamente orientadas. La propuesta conceptual y metodológica supuso así seguir lo literario como una manera de entender, en acto, los efectos de los libros en tanto mensajes y en tanto objetos en las prácticas de las juventudes contemporáneas en el marco de una sociedad signada por la expansión y consolidación de procesos de digitalización en la que, producto de estas mismas vinculaciones, se constituye un renovado y específico ecosistema de lecturas.

Analysis and mapping of the structure of suburban settlement of the city of Orel
Authors: Kiryunin Ivan , Tikhii Vladimir
Published: October 2022

From the late 1980s to the present, the “ceiling” of urbanization has been reached in the Oryol region—the share of the urban population is in the range of 62–66 %, around the city of Oryol, in rural areas, a large number of the population is concentrated, the number of which is growing. Often, in the territorial planning system, the area of contact between urban and rural territories is not distinguished in any way, the development strategy of this territory cannot have the expected result. In this regard, the main purpose of the work was an attempt to identify the suburban area of the city of Orel using the method of transport zoning, which is based on the analysis of transport communication. The method of transport zoning of suburban areas allows us to estimate the territorial concentration of the suburban population in individual parts of the district. Each zone differs in the transport conditions of settlement, including the conditions of transport service. The paper presents the result of the application of the methodology for identifying suburban areas as territories served by different modes of transport on the example of the city of Orel. Based on the assessment of the differentiation of transport mobility of the population, as the most important condition for the quality of life, the zoning of the suburb of Orel was carried out. Its structural zones are highlighted—the neighborhood of the city, the near suburb and the far suburb. To achieve the purpose of the study, data from the All-Russian population censuses, OpenStreetMap data, and field research information were used. Based on these data, maps were built in QGIS that visually display the phenomena under study, and the zoning of the Oryol Municipal District was carried out. The article also concludes that transport communication radically affects the settlement system of the population, demonstrates the tendency of settlement in areas with better transport links.

Authors: Rosalind Maria , Pulung Sari Retno Dewi
Published: October 2022

Tujuan dari penelitian ini untuk mengetahui karakteristik dan penilaian terhadap sistem pre project selling perumahan berdasarkan asas keseimbangan pasca diundangkannya Peraturan Pemerintah (PP) No. 12 Tahun 2021 tentang Perubahan atas PP No. 14 Tahun 2016 tentang Penyelenggaraan Perumahan dan Kawasan Permukiman. Penelitian menggunakan metode yuridis normatif dengan fokus pengkajian tekstual terhadap tulisan atau teks hukum. Sementara, pendekatan penelitian yang digunakan yaitu pendekatan kasus untuk membantu memahami penerapan norma hukum dalam praktiknya. Hasil penelitian menunjukan bahwa karakteristik sistem pre project selling memiliki karakteristik preventif bagi konsumen sebagai bentuk perlindungan dan kepastian hukum. Namun, belum dapat dikatakan seimbang terutama terhadap tanggung jawab developer karena masih bersifat merugikan dalam beberapa aspek, sehingga menjadi kontraproduktif terhadap keberlangsungan usaha para pengembang properti. Pemerintah diharapkan lebih peka dengan memperhatikan kembali hak dan kewajiban developer yang juga perlu diperjelas dan dilindungi, sehingga kepastian hukum dapat dirasakan semua pihak dalam kegiatan jual beli properti.

Thisarticle contributessearchingfor a sustainable solution tothe supply of LPG. A little research has been done in Peru regarding the supply of LPG; it is focusedon the analysis of the energy matrix,LPG distribution for vehicles, Government pricing policy orsupply sources. The lack of studies that carry out an analysis of the causes or the interrelation between different factors can affect the normal supply of this fuel. An analysis of the problematic situation following the soft system dynamics methodology allows an adequate definition of the problem and events generating of risks that are presented in the LPG Supply. As a result of its application, defining the unstructured problematic situation has included the situation description where events and circumstances are observed without having any kind of structure, arising as the occurrence of the LPG shortage without having a clearidea of the real factors that cause it. On the other hand, defining the structured problematic situation has involved concatenating all the elements that integrate the situation describing and analyzing the whole system, considering historical records of past situations and collecting needs, aspirations and expectations of the different stakeholders, contributing to form an image of the situation that shows the structure, processes, relevant events and interrelations between all the elements involved.Thus, it is observed how the variables in the phases of the value chain of the LPG are related and interact affecting their supply.
