Authors: Сизова И. Л. , Орлова Н. С.
Published: August 2021

В статье рассматриваются социальные процессы, сопровождающие реализацию политики «активного долголетия» в российской социальнотрудовой сфере. В первом разделе статьи кратко представляются основы концепции «активного долголетия» и обсуждаются возможные социальные механизмы ее применения. Особое место здесь отводится анализу социальных прав, которые формируют основу для разных моделей развития общественного благосостояния и качества жизни населения. Во втором разделе на базе парадигмы конструктивизма в социальных науках и теории символической власти П. Бурдьё предлагается авторский вариант изучения структур восприятия и оценивания населением реализованных государственных реформ. В третьем разделе представлены результаты эмпирического анализа серии полуструктурированных интервью с основными субъектами социально-трудовой сферы и текстов обращений граждан в органы государственной власти. В заключение интерпретируется символическая борьба вокруг восприятия политики «активного долголетия» в России. Авторы приходят к выводу о том, что ожидается новый всплеск программ социальной помощи пожилым и рост пассивности в их трудовом поведении.

The article examines the social processes accompanying implementation of the policy «active aging» in the Russian social and labor spheres. The basic concepts of «active aging» are brieﬂ y introduced and possible social mechanisms of its application are discussed in the ﬁrst section of the article. Special importance is given to the analysis of social rights which form the basis for different models of the development of public welfare and the population’s quality of life. In the second section, author’s version of studying the perception and assessment structures by the population of the implemented reforms of the State are proposed on the basis of the paradigm of constructivism in the social sciences and the theory of symbolic power by P. Bourdieu. In the third section the results of an empirical analysis of a set of semi-structured interviews with the main subjects of the social and labor spheres and the texts of citizens’ appeals to government bodies are presented. In conclusion, the symbolic struggle around the perception of the «active aging» policy in Russia is interpreted. The authors conclude that a new surge in social assistance programs for the elderly and an increase in passivity in their work behavior are expected.

Цель исследования - изучить влияние различных способов реабилитации после перелома лучевой кости в типичном месте на вариабельность ритма сердца и состояние факторов врожденного иммунитета, содержание IL -1, -2, -4, -6, -8, -10 у женщин пожилого возраста. У 50 женщин (средний возраст - 63,5±1,5 года) изучены показатели спектрального анализа ритма сердца на 3-и, 7-е, 14-е сутки реабилитационных процедур. Состояние клеточных факторов врожденного иммунитета оценивали по фагоцитарной активности и кислородзависимому метаболизму нейтрофильных гранулоцитов в тесте восстановления нитросинего тетразолия. Цитокиновый статус включал определение IL -1, -2, -4, -6, -8, -10 методом ИФА. Для проведения статистического анализа проведено вычисление критерия Шапиро-Уилка, односторонний точный критерий Фишера, t -критерий Стьюдента. Показано, что под влиянием реабилитационных мер с использованием метода постизометрической миорелаксации происходит снижение вариабельности ритма сердца у женщин пожилого возраста, восстановление баланса между симпатическим и парасимпатическими отделом вегетативной нервной системы, нормализация функционально-метаболического статуса нейтрофильных гранулоцитов и Th 1/ Th 2 лимфоцитов. Полученные результаты позволяют рекомендовать включение метода постизометрической миорелаксации в комплекс реабилитационных мер при переломах лучевой кости в типичном месте.

The purpose of the study is to study the effect of various methods of rehabilitation after a fracture of the radius in a typical location on the heart rate variability and the state of innate immunity factors, the content of IL -1, -2, -4, -6, -8, -10 in elderly women. In 50 women at the age of 63,5±1,5 years, the indicators of the spectral analysis of the heart rhythm were studied on the 3, 7, 14 days of rehabilitation procedures. The state of the cellular factors of innate immunity was assessed by the phagocytic activity and oxygen-dependent metabolism of neutrophilic granulocytes in the nitric blue tetrazolium reduction test. The cytokine status included the determination of IL -1, -2, -4, -6, -8, -10 by enzyme immunoassay. For the statistical analysis, the Shapiro-Wilks test, one-sided Fisher’s exact test, and Student’s t test were calculated. It has been shown that the inﬂuence of rehabilitation measures using the method of post-isometric muscle relaxation decreases the heart rate variability of elderly women, restores the balance between the sympathetic and parasympathetic parts of the autonomic nervous system, normalizes the functional and metabolic status of neutrophilic granulocytes and Th 1/ Th 2 lymphocytes. The results obtained allow us to recommend the inclusion of the method of post-isometric muscle relaxation in the complex of rehabilitation measures for fractures of the radius in a typical place.

Authors: Иорданишвили А. К.
Published: August 2021

Увеличение доли пожилых и старых людей в структуре населения является особенностью настоящего времени, которая охватывает практически весь мир. Постарение населения изменило область задач врачей разных специальностей, в том числе стоматологов, делая повышение качества оказания стоматологической помощи и жизни людей старших возрастных групп наиболее приоритетными. Важной в поддержании здоровья людей старших возрастных групп является биорегуляция, которая представляет сложный комплекс межклеточных взаимодействий, направленный на поддержание гомеостаза и отвечающий за течение таких важных физиологических процессов, как дифференцировка и деление клеток, регенерация тканей, старение организма, обмен и воспроизведение генетической информации и многое другое. Биорегулирующая терапия направлена на ликвидацию нарушений гомеостаза для нормализации функций поврежденных клеток, тканей и органов. Цель работы - исследовать основные направления использования, достижения и перспективы биорегулирующей терапии в области геронтостоматологии. Представлены основные результаты применения биорегулирующей терапии в геронтостоматологии при лечении заболеваний пародонта, слизистой оболочки полости рта, височно-нижнечелюстного сустава, одонтогенных гнойно-воспалительных заболеваний и очагов стоматогенной хронической инфекции, а также перспективы их дальнейшего применения.

The increase in the proportion of elderly and old people in the structure of the population is a feature of the present time, which covers almost the entire world. The aging of the population has changed the scope of tasks of doctors of various specialties, including dentists, making improving the quality of dental care and the life of older people a top priority. Bioregulation is important in maintaining the health of people of older age groups, which is a multiple complex of intercellular interactions aimed at maintaining homeostasis and responsible for the course of such important physiological processes as cell differentiation and division, tissue regeneration, aging of the body, exchange and reproduction of genetic information, and much other. Bioregulatory therapy is aimed at eliminating homeostasis disorders in order to normalize the functions of damaged cells, tissues and organs. The purpose of this work is to investigate the main directions of use, achievements and prospects of bioregulatory therapy in the ﬁeld of gerontostomatology. The main results of the use of bioregulatory therapy in gerontostomatology in the treatment of periodontal diseases, oral mucosa, temporomandibular joint, odontogenic purulent-inﬂammatory diseases and foci of stomatogenic chronic infection, as well as the prospects for their further use are presented.

Несмотря на очевидный прогресс в изучении вопросов лечения распространенных форм вторичного перитонита, ближайшие результаты далеки от удовлетворительных, в особенности у больных старших возрастных групп. В ряде случаев однократного оперативного вмешательства оказывается недостаточно для полноценной санации источника внутрибрюшной инфекции, что побуждает к проведению повторных санационных вмешательств, порядок и сроки выполнения которых на настоящий момент не являются строго регламентированными. Изучена эффективность применения лечебного алгоритма, подразумевающего дифференцированный подход к проведению плановых хирургических санаций в краткие сроки у больных с выраженными патоморфологическими изменениями в брюшной полости. Результаты лечения больных с применением плановых санационных вмешательств продемонстрировали эффективность разработанного алгоритма, позволив снизить общую послеоперационную летальность за счет сокращения удельного веса абдоминального сепсиса в структуре неблагоприятных исходов.

Despite the obvious progress in the treatment of secondary peritonitis common forms, the results are far from satisfactory, especially among patients of older age groups. In some cases, a single surgical intervention is not enough for a complete elimination of the intra-abdominal infection source, which leads to repeated sanitation interventions, the order and timing of which are currently not strictly regulated. The effectiveness of the treatment algorithm, which considers a differentiated approach to planned surgical interventions in a short time in patients with severe pathomorphological changes in the abdominal cavity, was studied. The results of treatment using planned sanitation interventions demonstrated the effectiveness of the developed algorithm, allowing to reduce the overall postoperative mortality by reducing the proportion of abdominal sepsis in the structure of adverse outcomes.

Для выявления взаимосвязи психических и физических нарушений в пожилом и старческом возрасте были обследованы 70 пациентов одной из поликлиник Архангельска, в том числе лица 60-74 лет - 56 (80 %), 75 лет и старше - 14 (20 %). Проведено анкетирование, изучены данные амбулаторных карт, использована оценка клинического статуса, а также методики для определения психического и физического состояния. Наиболее частыми психическими и физическими нарушениями были когнитивные и депрессивные расстройства, высокий риск синдрома мальнутриции, саркопении и синдрома падений, ухудшение функциональных возможностей, при этом больные старческого возраста имели достоверно более выраженные нарушения. Показано, что у лиц пожилого и старческого возраста когнитивные и депрессивные расстройства повышают риск синдрома падения и снижают функциональные возможности, а в старческом возрасте - увеличивают риск синдрома саркопении.

In order to identify the relationship between mental and physical disorders in the elderly and senile age, 70 patients were examined in one of the clinics in Arkhangelsk, including 56 (80 %) persons aged 60-74 years and 14 (20 %) people aged 75 years and older. A questionnaire was conducted, data from outpatient records were studied, and the clinical status assessment was used, as well as methods for determining mental and physical condition. The most frequent mental and physical disorders were the cognitive and depressive disorders presence, a high risk of malnutrition syndrome, sarcopenia and falls syndrome, reduced functional capabilities, while senile patients had significantly more pronounced disorders. It has been shown that the cognitive and depressive disorders presence in the elderly and senile increases the falling syndrome risk and reduced functional capabilities, and in old age - sarcopenia syndrome.

Целью работы являлось уточнение гендерных и возрастных различий в строении мозговых структур у здоровых добровольцев в связи с задачей разграничения визуальных паттернов физиологического старения и патологических процессов головного мозга. Методы исследования включали проведение структурной МРТ головного мозга у 131 условно-здорового добровольца 20-70 лет (из них 72 женщины и 59 мужчин). С помощью метода магнитно-резонансной воксель-базированной морфометрии проводили измерение объёма головного мозга в целом, а также его отделов с последующим сравнением полученных данных в возрастных подгруппах и между полами. Полученные в ходе исследования данные свидетельствуют о том, что наибольшее уменьшение размеров после 60 лет претерпевают правый и левый таламусы, левое хвостатое ядро, правая скорлупа, левый бледный шар, оба гиппокампа. Наибольшие изменения в гиппокампах претерпевает объём СА3 полей Бродмана. Установлено, что процесс физиологического старения головного мозга с изменением объёма его различных отделов имеет ряд гендерных особенностей, которые необходимо учитывать на диагностическом этапе медицинской помощи.

Published: August 2021

Пролапс тазовых органов (ПТО) является распространенным заболеванием у женщин в менопаузе и постменопаузе. ПТО является хроническим, медленно прогрессирующим заболеванием, приводящим к физическому и психоэмоциональному дискомфорту, приносящим физические и моральные страдания пациентки и снижающим качество жизни. Среди факторов, способствующих развитию данной патологии, выделяют акушерскую травму в анамнезе, ожирение, тяжелый физический труд, а также генетически детерминированную дисплазию соединительной ткани. Известны консервативные методы лечения ПТО, они редко используются, что обусловлено низкой эффективностью и запоздалой диагностикой данной патологии. Основным методом лечения является хирургический. Каждая третья гинекологическая операция в России выполняется по поводу пролапса. В настоящее время описано более 500 методов хирургической коррекции ПТО у женщин. Однако частота рецидивов достигает 38 %. Внедрение сетчатых имплантов также не привело к решению этой проблемы ввиду развития имплантассоциированных осложнений. Таким образом, в настоящее время является актуальным дальнейшее изучение причин развития пролапса тазовых органов с учетом генетических, фенотипических и клинико-анамнестических факторов риска пациентки, что будет способствовать разработке персонализированного подхода к выбору оптимального метода хирургического лечения в каждом отдельном случае.

Pelvic organ prolapse (POP) is a common condition in menopausal and postmenopausal women. POP is a chronic, slowly progressive disease that leads to physical and psycho-emotional discomfort, brings physical and moral suffering to the patient and reduces the quality of life. Among the factors contributing to the development of this pathology, there is a history of obstetric trauma, obesity, heavy physical labor, as well as genetically determined connective tissue dysplasia. Conservative methods of treating POP are known, but the low frequency of their use is due to low efficiency and late diagnosis of this pathology. The main method of treatment is surgical. Currently, more than 500 methods of surgical correction of POP in women have been described. However, the relapse rate reaches 38 %. The introduction of mesh implants also did not solve this problem due to the development of implant-associated complications. Thus, it is currently relevant to further study the causes of pelvic organ prolapse, taking into account the genetic, phenotypic and clinicalanamnestic risk factors of the patient, as well as to develop a personalized approach to choosing the optimal method of surgical treatment in each individual case.

The problem of identifying unstructured nonlinear systems is generally addressed on the basis of multi-model representations involving several linear local models. In the present work, local models are combined to get a global representation using incremental fuzzy clustering. The main contribution is a novel vector similarity measure defined in the System Working Space (SWS) that combines the angular deviation and the usual Euclidean distance. Such a combination makes the new metric highly discriminating leading to a better partitioning of the operating space providing, thereby, a higher accuracy of the model. The developed partitioning method is first evaluated by performing linear local model (LLM) based identification of a academic benchmark multivariable nonlinear system. Then, the performances of the identification method are evaluated using experimental tropospheric ozone data. These evaluations illustrate the supremacy of the new method over the standard Euclidian-distance based partitioning approach.

Coronavirus (COVID-19) is spreading rapidly around the world and, as of October 2020, more than 1,966,000 people have been infected in more than 200 countries. Early detection of COVID-19 is essential for the provision and protection of HIV-negative people in adequate health care for patients. To do this, we developed an automated diagnostic program for COVID-19 from pneumonia (CPA) obtained from chest tomography (CT). We propose, in particular, the Noise Resilient method of machine learning that focuses on regions of lung infection while making diagnostic decisions. Note that the sizes of the infection sites between COVID-19 and CAP are not well measured, in part due to the rapid progression of COVID-19 after the onset of symptoms. Large amounts of CVID-19 CT data from hospitals have been used to evaluate our frameworks.

“Refugee” is a historically constructed term that privileged concerns that are substantially ideological and political rather than economic and ecological. But one cannot neglect the fact that environmental and economic concerns cannot be set apart from the political and hence rises the necessity to create a new inclusive category of “ essential needs” to consider their intrinsic interconnectivity as its one of the apriorism. Refugee literature essentially addresses not only the displacement but the gaps that are found in the sociological approach to “statelessness” and migration. On the other hand, literature stands for individual expressions and experience. Literature in the context of statelessness not only signifies the notion of being a “refugee” but being an “ asylum, seeker” as well. No Friend but the Mountains by Behrouz Boochani is such an autobigraphcial novel written in the backdrop of his experience as an asylum seeker and consequent incarceration in the Australian detention regime. The Australian detention centre is built and worked in such a way that it satisfies the idea of the panopticon. The Kyriarchal system works in the prison even in a way that affects the psyche of the imprisoned individuals and thus these stateless asylum seekers undergo extreme existential dilemmas and commit severe crimes, turning against one another and sometimes even suicides. On the basis of the experiences of Boochani, the carceral system of Australian detention centre is expounded here through a Foucaludean idea of punishment, Bentham’s notion of the panopticon as well Fiorenza’s idea of kyriarchy where all of them are essentially different shades and shapes of exerting power.

Automated teller machine (ATM) nowadays are a favourite spot for attackers as they are available everywhere and are much easier to rob. Generally, ATM attacks can be either physical ATM attacks or ATM-related fraud attacks. In this paper the idea of an ATM system with multilayer security is proposed with the help of internet of things (IoT), fingerprint identification and face recognition to increase the security of ATM. The physical ATM counter attacks can be identified by using specific sensors to detect changes in vibration and temperature in the ATM counter. To prevent ATM related fraud attacks the proposed system has additional security features like fingerprint identification and face recognition along with ATM number verification. The convolutional neural network (CNN) and machine learning based face recognition is used in this work which is quite reliable. Failures in any of the above steps cancel the transactions and so the proposed system provides multi layer security which makes it impossible for the attackers to break the ATM security. The proposed system will help to increase the security of the ATM and provide safe and secure ATM transactions.

Herein presented, we demonstrate that a sensitive sensing/detection element was obtained from the laser treatment of a non-conducting flexible material exploiting laser machine, which can then potentially deploy as sensing element of a biosensor for possible usage in to sense and obtain the presence and quantity of the interested sample. The goal is to study and advance innovative means of fabricating a low-cost graphene sensor, employed as a Radio Frequency (RF) filter for disposable biomedical purposes. A material like Graphene can be fashioned by laser irradiation (Laser scribe) of Kapton tape implemented as a filter. The manufacture of the filter geometry was accomplished by means of a laser machine irradiating a Kapton tape on a chosen substrate (for this work a Flame Retardant 4 (FR-4)), by the application of the previous gotten parameters for the production. Various laser power values were employed for their manufacture and their corresponding conductivity was observed to range from 171 x10-6 S/mm to 279 x10-6 S/mm. The Raman spectrum results of the produced material has a D band peak at 1349.76 cm-1 , a G band of 1587.73 cm-1 and a 2D band peak of 2693.34 cm-1 . The ANSYS high-frequency structure simulator (HFSS) (for the Analysis of the System) simulation results signifies good outcomes, and opportunities to improve the material property are also being studied. Tests were also conducted by the utilization of a Vector Network Analyzer (VNA) to validating their feasibility of being deployed as the detection element of a biosensor, thus lending them the possibility to find implementation in disposable biological sensing.

Credit card fraud is a serious criminal offense. It costs individuals and financial institutions billions of dollars annually. According to the reports of the Federal Trade Commission (FTC), a consumer protection agency, the number of theft reports doubled in the last two years. It makes the detection and prevention of fraudulent activities critically important to financial institutions. Machine learning algorithms provide a proactive mechanism to prevent credit card fraud with acceptable accuracy. In this paper Machine Learning algorithms such as Logistic Regression, Naïve Bayes, Random Forest, K- Nearest Neighbor, Gradient Boosting, Support Vector Machine, and Neural Network algorithms are implemented for detection of fraudulent transactions. A comparative analysis of these algorithms is performed to identify an optimal solution.

Authentication is a process of verifying the credibility of a user who is trying to access classified or confidential information. There is a vast unfold in the number of internet users, and the demand for IoT devices, cloud services has been increasing; it is now essential more than ever to protect the data hosted on the internet. So, the authentication process cannot be relied on single-factor static authentication methods to verify the user credentials. All devices in the market are not equipped with biometric systems, so a form of multi-factor authentication which is independent of biometrics needs to be adopted for a secure authentication system. This paper portraits a systematic architecture to verify user credentials using specific parameters, trying to unfold patterns using machine learning algorithms based on user's past login records, thus trying to provide a safer and secure authentication process for the users.

Transformator merupakan unsur utama dan merupakan mata rantai terpenting dalam penyaluran dan distribusi tenaga listrik. Sehingga diperlukan sistem proteksi yang selektif, andal, sensitif, dan cepat untuk menjaga keandalan trafo. Salah satu komponen proteksi trafo adalah CT (trafo arus) yang berfungsi sebagai pembaca arus proteksi relay, apabila terjadi gangguan maka relay proteksi mendeteksi adanya keabnormalan sehingga  memberikan sinyal trip pada PMT untuk memutus rangkaian listrik. Relay pada sistem proteksi trafo memiliki lokasi pengamanan yang berbeda. Di PT. PLN (Persero) UPT Cirebon, terjadi gangguan pada bay trafo yang mengakibatkan relay bekerja. Namun kerja relay ini tidak sesuai dengan lokasi gangguan yang terjadi. Setelah diinvestigasi didapatkan bahwa  CT pada bay trafo memiliki desain peletakan yang kurang tepat sehingga mengakibatkan salah kerja relay (kurang selektif). Untuk memperbaiki kesalahan tersebut, maka dilakukan perubahan wiring CT pada trafo produksi lama. Perubahan wiring CT ini disesuaikan dengan ketentuan SPLN T5.003-2010 Tentang Standar Pola Proteksi Transformator Tenaga sehingga apabila terjadi gangguan relay bekerja sesuai dengan lokasi proteksinya. Hal ini terbukti pada saat terjadi gangguan setelah dilakukan perubahan wiring relay bekerja sesusai dengan fungsinya, sehingga prinsip sistem proteksi terpenuhi, yaitu selektif, andal, sensitif dan cepat.
