Background and Objectives: In Coronavirus Disease 2019 (COVID-19), which is caused by the infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the clinical manifestations are primarily related to the pulmonary system. Under 10% of cases also develop gastrointestinal events such as diarrhea, nausea, vomiting and abdominal pain. Materials and Methods: We conducted an observational, retrospective study in the Infectious Diseases Clinic of “Victor Babes” Hospital, Timis County, in order to assess the incidence, outcome and risk factors for clostridium difficile infection (CDI) in COVID-19 patients. Results: Out of 2065 COVID-19 cases, hospitalized between 1st September 2020 and 30th April 2021, 40 cases of CDI were identified with 32 cases of hospital-onset of CDI and eight cases of community-onset and healthcare-associated CDI. By randomization, polymerase chain reaction ribotyping of Clostridium Difficile was performed in six cases. All the randomized cases tested positive for ribotype 027. The percentage of cases recovered with complications at discharge was higher among COVID-19 patients and CDI (p = 0.001). The in-hospital stay, 36 days versus 28 days, was longer among COVID-19 patients and CDI (p = 0.01). The presence of previous hospitalization (p = 0.004) and administration of antibiotics during the hospital stay, increased the risk of CDI among COVID-19 patients. The mean adjusted CCI at admission was lower among controls (p = 0.01). In two cases, exitus was strictly CDI-related, with one case positive for 027 ribotype. Conclusions: CDI has complicated the outcome of COVID-19 patients, especially for those with comorbidities or previously exposed to the healthcare system. In the face of the COVID-19 pandemic and the widespread, extensive use of antibiotics, clinicians should remain vigilant for possible CDI and SARS-CoV-2 co-infection.

Published: October 2021

Research indicates that the projection of traffic volumes is a valuable tool for traffic management. However, few studies have examined the application of a universal automated framework for car traffic volume prediction. Within this limited literature, studies using broad data sets and inclusive predictors have been inadequate; such works have not incorporated a comprehensive set of linear and nonlinear algorithms utilizing a robust cross-validation approach. The proposed model pipeline introduced in this study automatically identifies the most appropriate feature-selection method and modeling approach to reduce the mean absolute percentage error. We utilized hyperparameter optimization to generate a universal automated framework, distinct from model optimization techniques that rely on a single case study. The resulting model can be independently customized to any respective project. Automating much of this process minimizes the work and expertise required for traffic count forecasting. To test the applicability of our models, we used Florida historical traffic data from between 2001 and 2017. The results confirmed that nonlinear models outperformed linear models in predicting passenger vehicles’ monthly traffic volumes in this specific case study. By employing the framework developed in this study, transportation planners could identify the critical links on US roads that incur overcapacity issues.

Sustainable wastewater treatment is one of the biggest issues of the 21st century. Metals such as Zn2+ have been released into the environment due to rapid industrial development. In this study, dried watermelon rind (D-WMR) is used as a low-cost adsorption material to assess natural adsorbents’ ability to remove Zn2+ from synthetic wastewater. D-WMR was characterized using scanning electron microscope (SEM) and X-ray fluorescence (XRF). According to the results of the analysis, the D-WMR has two colours, white and black, and a significant concentration of mesoporous silica (83.70%). Moreover, after three hours of contact time in a synthetic solution with 400 mg/L Zn2+ concentration at pH 8 and 30 to 40 °C, the highest adsorption capacity of Zn2+ onto 1.5 g D-WMR adsorbent dose with 150 μm particle size was 25 mg/g. The experimental equilibrium data of Zn2+ onto D-WMR was utilized to compare nonlinear and linear isotherm and kinetics models for parameter determination. The best models for fitting equilibrium data were nonlinear Langmuir and pseudo-second models with lower error functions. Consequently, the potential use of D-WMR as a natural adsorbent for Zn2+ removal was highlighted, and error analysis indicated that nonlinear models best explain the adsorption data.
The Peripheral Cannabinoid Receptor Type 1 (CB1) as a Molecular Target for Modulating Body Weight in Man
Authors: O’Sullivan Saoirse Elizabeth , Yates Andrew S. , Porter Richard K.
Published: October 2021

The cannabinoid 1 (CB1) receptor regulates appetite and body weight; however, unwanted central side effects of both agonists (in wasting disorders) or antagonists (in obesity and diabetes) have limited their therapeutic utility. At the peripheral level, CB1 receptor activation impacts the energy balance of mammals in a number of different ways: inhibiting satiety and emesis, increasing food intake, altering adipokine and satiety hormone levels, altering taste sensation, decreasing lipolysis (fat break down), and increasing lipogenesis (fat generation). The CB1 receptor also plays an important role in the gut–brain axis control of appetite and satiety. The combined effect of peripheral CB1 activation is to promote appetite, energy storage, and energy preservation (and the opposite is true for CB1 antagonists). Therefore, the next generation of CB1 receptor medicines (agonists and antagonists, and indirect modulators of the endocannabinoid system) have been peripherally restricted to mitigate these issues, and some of these are already in clinical stage development. These compounds also have demonstrated potential in other conditions such as alcoholic steatohepatitis and diabetic nephropathy (peripherally restricted CB1 antagonists) and pain conditions (peripherally restricted CB1 agonists and FAAH inhibitors). This review will discuss the mechanisms by which peripheral CB1 receptors regulate body weight, and the therapeutic utility of peripherally restricted drugs in the management of body weight and beyond.

Published: October 2021

Traditionally, the supplement of organic manure in tea plantations has been a common approach to improving soil fertility and promoting terroir compounds, as manifested by the coordinated increase in yield and quality for the resulting teas. However, information regarding the effect of organic manure in the metabolome of tea plants is still inadequate. The metabolite profiles of tea shoots applied with cow manure, urea or no fertilizer were studied using gas chromatography–mass spectrometry (GC–MS). In total, 73 metabolites were detected, and the modulated metabolites included mainly amino acids, organic acids and fatty acids. In particular, glutamine, quinic acid and proline accumulated more in tea shoots in soils treated with cow manure, but octadecanoic acid, hexadecanoic acid and eicosanoic acid were drastically reduced. Pearson correlation analysis indicated that organic acids and amino acids in tea shoots were the two major metabolite groups among the three treatments. The analysis of metabolic pathways demonstrated that the cow manure treatment significantly changed the enrichment of pathways related to amino acids, sugars and fatty acids. Sensory evaluation showed that the quality of green teas was higher when the plants used to make the tea were grown in soil treated with cow manure rather than urea during spring and late summer. The results indicated that the application of cow manure in soils changed the metabolic characteristics of tea shoots and improved the qualities of the resulting teas.

The aim of the study was to establish the complete microbiological profile of boar semen (Sus scrofa domesticus) and to choose the most effective antiseptic measures in order to control and optimize AI reproduction in pig farms. One hundred and one semen samples were collected and analyzed from several pig farms. The microbiological profile of ejaculates was determined by evaluating the degree of contamination of fresh semen and after dilution with specific extenders. The bacterial and fungal load of fresh boar semen recorded an average value of 82.41/0.149 × 103 CFU/mL, while after diluting the ejaculates the contamination value was 0.354/0.140 × 103 CFU/mL. Twenty-four germs (15 bacterial and 9 fungal species) were isolated, the most common being Candida parapsilosis/sake (92%) and Escherichia coli (81.2%). Modification of the sperm collection protocol (HPBC) reduced contamination in raw sperm by 49.85% in bacteria (significant (p < 0.00001) and by 9.67% in fungi (non-significant (p < 0.111491). The load in bacteria and filamentous fungi can be controllable, but not in levuras fungi. Some fluconazole-added extenders (12.5 mg%), ensure fungal aseptization, and even an increase in sperm progressivity (8.39%) for at least a 12 h shelf life after dilution. Validation of sperm aseptization was done by maintaining sow fecundity unchanged after AI (insignificant p > 0.05).
Surface Modification of Bamboo Charcoal by O2 Plasma Treatment and UV-Grafted Thermo-Sensitive AgNPs Hydrogel to Improve Antibacterial Properties in Biomedical Application
Authors: Liu Shih-Ju , Liao Shu-Chuan
Published: October 2021

With the advancement of science and modern medical technology, more and more medical materials and implants are used in medical treatment and to improve human life. The safety of invasive medical materials and the prevention of infection are gradually being valued. Therefore, avoiding operation failure or wound infection and inflammation caused by surgical infection is one of the most important topics in current medical technology. Silver nanoparticles (AgNPs) have minor irritation and toxicity to cells and have a broad-spectrum antibacterial effect without causing bacterial resistance and other problems. They are also less toxic to the human body. Bamboo charcoal (BC) is a bioinert material with a porous structure, light characteristics, and low density, like bone quality. It can be used as a lightweight bone filling material. However, it does not have any antibacterial function. This study synthesized AgNPs under the ultraviolet (UV) photochemical method by reducing silver nitrate with sodium citrate. The formation and distribution of AgNPs were confirmed by UV-visible spectroscopy and X-ray diffraction measurement (XRD). The BC was treated by O2 plasma to increase the number of polar functional groups on the surface. Then, UV light-induced graft polymerization of N-isopropyl acrylamide (NIPAAm) and AgNPs were applied onto the BC to immobilize thermos-/antibacterial composite hydrogels on the BC surface. The structures and properties of thermos-/antibacterial composite hydrogel-modified BC surface were characterized by Scanning Electron Microscopy (SEM), Fourier Transform Infrared spectrum (FT-IR), and X-ray photoelectron spectroscopy (XPS). The results show that thermos-/antibacterial composite hydrogels were then successfully grafted onto BC. SEM observations showed that the thermos-/antibacterial composite hydrogels formed a membrane structure between the BC. The biocompatibility of the substrate was evaluated by Alamar Blue cell viability assay and antibacterial test in vitro.
The Ibtihalat in the Digital Age: Public and Private Domains
Authors: Abdelfattah Heba Arafa
Published: October 2021

One of the most popular cultures in Islam is the genre of “hymns” or “invocations” (pl. ibtihalat, sing. ibtihal), which has recently been amplified on social media platforms. The ibtihalat are Arabic short poems performed by a sheikh known as the “supplicator” (mubtahil). They air regularly on Arabic TV stations and more frequently on radio stations, especially those broadcasting about the Qur’an, its recitation, and its interpretation. In Egypt, the Qur’an’s radio station, which has millions of followers, launched a YouTube station that airs ibtihalat before and after dawn prayer daily. The viewership of one ibtihal like that of Sheikh Sayyid al-Naqshabandi’s “My Lord” (Mawlay) reached 11 million on YouTube. The ibtihalat are also integral parts of Islamic festivities during the two Eids and Ramadan. Focusing on al-Naqshabandi’s ibtihal “My Lord” (Mawlay), this paper discusses the genre of Islamic hymns as a popular culture approach to study Islam as a lived experience based on the inclusion, not the elimination, of difference. To that end, I explore how the ibtihal becomes a domain for contemplating the place of the self in the present moment without the gaze of authority and how this reconfiguration of authority within the self has deep roots in the Islamic notion of “unicity of God” (tawhid).

Authors: Nagao Yumiko , Takahashi Hirokazu , Kawaguchi Atsushi , Kitagaki Hiroshi
Published: October 2021

The worldwide increase in nonalcoholic fatty liver disease (NAFLD) is a major public health problem. Obesity and diabetes are risk factors for NAFLD and the development of liver fibrosis is a risk factor for liver cancer. Periodontal disease bacteria can also exacerbate NAFLD. We previously reported that amazake, a traditional Japanese fermented food, improves the quality of life (QOL) of patients with liver cirrhosis. In this study, we investigated the effect of amazake intake on NAFLD patients with periodontal disease. Ten patients (mean age: 57.1 ± 19.2 years) consumed 100 g of amazake daily for 60 days. On days 0 and 60, their body mass index (BMI), body fat percentage, serum biochemical parameters, periodontal disease bacteria in saliva, and ten visual analog scales (VASs), namely, sense of abdomen distension, edema, fatigue, muscle cramps, loss of appetite, taste disorder, constipation, diarrhea, depression, and sleep disorder, were measured. For periodontal bacteria, the numbers of six types of bacteria in saliva (Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Aggregatibacter actinomycetemcomitans, Prevotella intermedia, and Fusobacterium necleatum) and P. gingivalis-specific fimA genotype were determined. After 60 days of amazake consumption, eosinophils (p < 0.05), immune reactive insulin (IRI) (p < 0.01), and HOMA-IR (p < 0.05) had significantly increased and tumor necrosis factor α (TNFα) (p < 0.01), muscle cramps (p < 0.05), and depression (p < 0.05) had significantly decreased. All subjective symptoms improved after amazake intake. No change was observed in the periodontal bacteria. In conclusion, amazake significantly decreased TNFα and improved the QOL of the patients with NAFLD and periodontitis. However, caution should be exercised because amazake, which is manufactured using techniques that lead to concentrations of glucose from the saccharification of rice starch, may worsen glucose metabolism in NAFLD patients. Amazake may be an effective food for improving the symptoms of a fatty liver if energy intake is regulated.

Published: October 2021

This article discusses the process of creating a digital forest model based on remote sensing data, three-dimensional modeling, and forest inventory data. Remote sensing data of the Earth provide a fundamental tool for integrating subsequent objects into a digital forest model, enabling the creation of an accurate digital model of a selected forest quarter by using forest inventory data in educational and experimental forestry, and providing a valuable and extensive database of forest characteristics. The formalization and compilation of technologies for connecting forest inventory databases and remote sensing data with the construction of three-dimensional tree models for a dynamic display of changes in forests provide an additional source of data for obtaining new knowledge. The quality of forest resource management can be improved by obtaining the most accurate details of the current state of forests. Using machine learning and regression analysis methods as part of a digital model, it is possible to visually assess the course of planting growth, changes in species composition, and other morphological characteristics of forests. The goal of digital, interactive forest modeling is to create virtual simulations of the future status of forests using a combination of predictive forest inventory models and machine learning technology. The research findings provide a basic idea and technique for developing local digital forest models based on remote sensing and data integration technologies.
WiFi Fingerprinting Indoor Localization Based on Dynamic Mode Decomposition Feature Selection with Hidden Markov Model
Authors: Babalola Oluwaseyi Paul , Balyan Vipin
Published: October 2021

Over the years, WiFi received signal strength indicator (RSSI) measurements have been widely implemented for determining the location of a user’s position in an indoor environment, where the GPS signal might not be received. This method utilizes a huge RSSI dataset collected from numerous access points (APs). The WiFi RSSI measurements are nonlinear with distance and are largely influenced by interference in the indoor environment. Therefore, machine learning (ML) techniques such as a hidden Markov model (HMM) are generally utilized to efficiently identify a trend of RSSI values, which corresponds to locations around a region of interest. Similar to other ML tools, the performance and computing cost of the HMM are dependent on the feature dimension since a large quantity of RSSI measurements are required for the learning process. Hence, this article introduces a feature extraction method based on dynamic mode decomposition (DMD) for the HMM to effectively model WiFi fingerprint indoor localization. The DMD is adopted since it decomposes RSSIs to meaningful spatial and temporal forms over a given time. Here, the mode forms are analytically reconstructed to produce low-dimensional feature vectors, which are used with the HMM. The localization performance of the proposed HMM-DMD is compared with other well-known ML algorithms for WiFi fingerprinting localization using simulations. The results show that the HMM-DMD algorithm yields a significant localization performance improvement, accuracy, and reasonable processing time in comparison with the state-of-the-art algorithms.

Authors: Koszewnik Andrzej , Lesniewski Kacper , Pakrashi Vikram
Published: October 2021

This paper investigates damage identification metrics and their performance using a cantilever beam with a piezoelectric harvester for Structural Health Monitoring. In order to do this, the vibrations of three different beam structures are monitored in a controlled manner via two piezoelectric energy harvesters (PEH) located in two different positions. One of the beams is an undamaged structure recognized as reference structure, while the other two are beam structures with simulated damage in form of drilling holes. Subsequently, five different damage identification metrics for detecting damage localization and extent are investigated in this paper. Overall, each computational model has been designed on the basis of the modified First Order Shear Theory (FOST), considering an MFC element consisting homogenized materials in the piezoelectric fiber layer. Frequency response functions are established and five damage metrics are assessed, three of which are relevant for damage localization and the other two for damage extent. Experiments carried out on the lab stand for damage structure with control damage by using a modal hammer allowed to verify numerical results and values of particular damage metrics. In the effect, it is expected that the proposed method will be relevant for a wide range of application sectors, as well as useful for the evolving composite industry.

Published: October 2021

The differences between urban and rural B&Bs should be emphasized, which is critical for the sustainable development of the B&B industry. This study identified and compared the topics that customers were concerned about for urban and rural B&Bs in Beijing by analyzing 13,241 online reviews obtained from the website Ctrip. The results showed that customers focused on 10 common topics: “room”, “location”, “host”, “experience”, “surroundings”, “facilities”, “service”, “design/style”, “value”, and “entertainment”. However, the importance of each topic varied between urban and rural B&Bs. Customers paid more attention to the room. Urban B&B customers were more concerned about location. The convenience of urban B&Bs was more prominent than that of rural B&Bs, especially in terms of public transportation and commercial services. While rural B&B customers were more concerned about experience, service, design/style, and entertainment. In addition, the “host” is the most crucial and influential factor in the development of B&Bs. This study made contributions to customer perceptions of B&Bs from a comparative perspective and enriched the understanding of the characteristics of urban and rural B&Bs. In the part of practice, this study might provide enlightenment for B&B operators and local governments to take measures for B&Bs sustainable development.

We successfully analyzed the data, including the potential relationships, internal relationships, and operation laws between the data, to detect the safety statuses of hydrogen refueling stations.
Identifying how GPs spend their time and the obstacles they face: a mixed-methods study
Authors: Sinnott Carol , Moxey Jordan M , Marjanovic Sonja , Leach Brandi , Hocking Lucy , Ball Sarah , Georgiadis Alexandros , Lamé Guillaume , Willars Janet , Dixon-Woods Mary
Published: October 2021

Background

Although problems that impair task completion — known as operational failures — are an important focus of concern in primary care, they have remained little studied.

Aim

To quantify the time GPs spend on different activities during clinical sessions; to identify the number of operational failures they encounter; and to characterise the nature of operational failures and their impact for GPs.

Design and setting

Mixed-method triangulation study with 61 GPs in 28 NHS general practices in England from December 2018 to December 2019.

Method

Time–motion methods, ethnographic observations, and interviews were used.

Results

Time–motion data on 7679 GP tasks during 238 hours of practice in 61 clinical sessions suggested that operational failures were responsible for around 5.0% (95% confidence interval [CI] = 4.5% to 5.4%) of all tasks undertaken by GPs and accounted for 3.9% (95% CI = 3.2% to 4.5%) of clinical time. However, qualitative data showed that time–motion methods, which depend on pre-programmed categories, substantially underestimated operational failures. Qualitative data also enabled further characterisation of operational failures, extending beyond those measured directly in the time–motion data (for example, interruptions, deficits in equipment/supplies, and technology) to include problems linked to GPs’ coordination role and weaknesses in work systems and processes. The impacts of operational failures were highly consequential for GPs’ experiences of work.

Conclusion

GPs experience frequent operational failures, disrupting patient care, impairing experiences of work, and imposing burden in an already pressurised system. This better understanding of the nature and impact of operational failures allows for identification of targets for improvement and indicates the need for coordinated action to support GPs.

Gestión de la responsabilidad social territorial y su relación con la educación superior de calidad
Authors: Huamanchumo Sánchez Lilly
Published: October 2021

La crisis actual que atraviesa la Universidad y que afecta seriamente su actuación en la sociedad, radica –más allá del papel del Estado-, en el insuficiente quehacer de la formación académica, el limitado trabajo de investigación científica, la inadecuada puesta en marcha de la extensión universitaria, la poca elucidación en torno a lo que significa la responsabilidad social y arraigada en una visión empresarial. El objetivo de la investigación es conocer si la GRST está fuertemente relacionada con la Educación Superior de Calidad (ESC) porque creemos que su implementación en las universidades de laregión, especialmente de Perú, coadyuvaría a que desde un nuevo enfoque de RSU se avance hacia la calidad de la educación superior desde una gestión responsable que la contemple, sin descuidar su rol social. Como conclusión, según Rho de Spearman, La GRST (gestión institucional, formación profesional, investigación,    extensión     universitaria) y  la  ESC   (actuación,   autonomía, crítica, diversidad, equitativa, inclusiva, efectividad, pertinencia) tienen una fuerte y significativa relación a percepción de sus autoridades en las universidades de Perú, 2019, por lo que, si se implementa la GRST en las universidades peruanas, esta tendría éxito gracias a la correspondencia entre ambas variables.

Authors: Toloueiashtian Mahnaz , Golsorkhtabaramiri Mehdi , Bozorgi Rad Seyed Yaser
Published: October 2021

Todays, dynamic power management methods that decrease the energy use of sensor networks after their design and deployment are of paramount importance. In Wireless Sensor Networks (WSN), coverage and detection quality are one aspect of service quality and power consumption reduction aspect. The aim of the coverage problem is to monitor at least one node at each point in the targeted area and is divided into three categories: border, area, and point coverage. In point coverage, which is our interest, the problem is to cover specific points of the environment scattered on the surface of the environment; their position is decided on and called the goal. In this paper, a new metaheuristic algorithm based on Whale Optimization Algorithm (WOA) is proposed. The proposed algorithm tries to find the Best Solution (BS) based on three operations exploration, spiral attack, and siege attack. Several scenarios, including medium, hard and complex problems, are designed to evaluate the proposed technique, and it is compared to Genetic Algorithm (GA) and Ant Colony Optimization (ACO) based on time complexity criteria in providing a suitable coverage, network lifetime, energy consumption. The simulation results show that the proposed algorithm performs better than the compared ones in most scenarios.
Data Streams Oriented Outlier Detection Method: A Fast Minimal Infrequent Pattern Mining
Authors: Zhou ZhongYu , Pi DeChang
Published: October 2021

Outlier detection is a common method for analyzing data streams. In the existing outlier detection methods, most of methods compute distance of points to solve certain specific outlier detection problems. However, these methods are computationally expensive and cannot process data streams quickly. The outlier detection method based on pattern mining resolves the aforementioned issues, but the existing methods are inefficient and cannot meet requirements of quickly mining data streams. In order to improve the efficiency of the method, a new outlier detection method is proposed in this paper. First, a fast minimal infrequent pattern mining method is proposed to mine the minimal infrequent pattern from data streams. Second, an efficient outlier detection algorithm based on minimal infrequent pattern is proposed for detecting the outliers in the data streams by mining minimal infrequent pattern. The algorithm proposed in this paper is demonstrated by real telemetry data of a satellite in orbit. The experimental results show that the proposed method not only can be applied to satellite outlier detection, but also is superior to the existing methods.

Authors: Bashir Adil , Mir Ajaz Hussain
Published: October 2021

Internet of Things (IoT) is a smart interconnection of miniature sensors, enabling association of large number of smart objects ranging from assisted living and e-health to smart cities. IoT devices are equipped with limited resources in terms of power, memory and processing capabilities, therefore, presenting novel challenges to security. The purpose of this paper is to design energy efficient security mechanism for IoT based e-health system in which medical data is encrypted using lightweight cryptographic operations. The proposed scheme provides end-to-end data confidentiality for mobility enabled e-health IoT system. Our security scheme is simple and can be computed quickly on scarce resourced motes while providing required security services. Further, the mobility of patients is managed securely without the need of frequent reconfigurations during their movement within hospital/home premises. The evaluation results demonstrate that the proposed scheme reduces energy utilization to 17.84% and increases longevity of motes by 5.6 times compared to Certificate-Based Datagram Transport Layer Security (CB-DTLS). Energy consumption in configuration handover during mobility is handled by resource-rich devices, which make this scheme efficient in managing mobility of sensors. This work can be used as a basis for future research on securing patient data in an e-health system using energy efficient cryptographic operations.

Published: October 2021

Trabzonlu Emîn Hilmi 19. yy şair ve yazarlarındandır. Çeşitli kademelerdeki devlet memurluğundan başka, gazete muharrirliği ve Osmanlı Devleti’nin ilk Meclis-i Mebûsânında mebusluk görevi yapmıştır. Manzum ve mensur eserler kaleme almış, bunların bazıları yayımlanmıştır. Yazdığı müşterek gazeller ve çeşitli olaylara düşürdüğü tarih manzumeleriyle dikkat çekmektedir. Çeşitli devlet yetkililerine ithaf ettiği kasidelerinde, memurluk görevlerinde yaşadığı haksızlık ve yanlışlıkları dile getirip taleplerde bulunmuştur. Farklı nazım şekilleriyle kaleme aldığı manzumeleri Dîvân’ında toplayan Emîn Hilmi’nin, Münşeât’ına kaydettiği iki kısa kasidesi daha vardır. Bunlardan birini 1293’te tahta geçen V. Murâd’ın cülusu sebebiyle kaleme almış ve Bâb-ı Âlî’ye takdim etmiştir. Kasidenin her mısraıyla cülus tarihini tespit ederek padişaha dualar etmiştir. Diğer kasidesi de Trabzon defterdarlığına tayin edilen Âkif Efendi’nin övgüsünü içermektedir. Aynı zamanda şair ve münşi olan Âkif’in bu özelliğini belirterek, ondan lütuf ve himmet beklentisini îma etmiştir. Hilmi’nin Münşeât’ında, bu iki kasidesinden başka beyit ve kıtalar da mevcut olup makalede bunlara da yer verilmiştir.

Introduction: The relevance of the study is determined by the national goals of strategic development providing for sustainable population growth and an increase in active life expectancy, primarily in demographically disadvantaged areas to which most of the regions of the Russian Arctic Zone belong. Objective: To assess changes in the demographic structure of the Murmansk Region, one of the most industrially developed regions of the Russian Arctic, and the loss of its labor potential in 1989–2019 in order to substantiate the necessity to consider these changes for better planning of health care and adjusting the resource provision of the regional health care system. Materials and methods: We studied demographic characteristics of the population residing in administrative areas of the Murmansk Region with the main town-forming metals and mining enterprises by comparing data for 1989 with those for the years 1999, 2009, and 2015–2019 to establish trends in medical demography situation. The average age of the population was estimated as the arithmetic mean based on distribution of the population by age groups. Results: We established a significant decrease in the size of population of the Murmansk Region in 1989–2019 (by 34.8 %) accompanied by changes in the demographic profile. The increase in the average age of the population was attributed to the sharp decline in the child population, a decrease in the number of people of working age (16–59 years), and a significant increase in the population of older age groups. Changes in the age structure of the population had a significant effect on the old age dependency ratio, which demonstrated a 2.7 and 3.2-fold increase over the three 1989-to-2019 decades in the region and its industrial monotowns, respectively. Conclusion: The negative structural demographic trend resulted in a pronounced regressive regional age and sex pyramid, which by 2019 had a characteristic unstable shape with a relatively narrow base and a slope of its top to the left due to the significant predominance of the female population in the older age group. The observed changes in the demographic profile of the population suggest the need to consider this trend when planning local social policy including the volume and resource provision of health care services.

Authors: Loginova NN
Published: October 2021

Introduction: Occupational polyneuropathy of upper extremities induced by physical overload is often registered among workers of various occupations. Yet, modern science lacks up-to-date results of a comprehensive assessment of the condition of such patients in terms of occupational disease severity and the presence of concomitant non-occupational diseases.
Objective: To establish severity of the occupational disease and comorbidity status in workers of various occupations, to assess their significance for planning measures aimed at professional rehabilitation of patients.
Materials and methods: Severity of occupational polyneuropathy and comorbidity status were established in agricultural, construction, industrial, and mining workers.
Results: In all cohorts of workers, occupational polyneuropathy is generally registered in middle-aged and elderly people usually experiencing moderate symptoms; in most cases, it is combined with other occupational diseases of the musculoskeletal system and the peripheral nervous system. Miners suffering from this type of polyneuropathy are often diagnosed with chronic industrial bronchitis. Of non-occupational disorders, ischemic heart disease, hypertension, dorsopathies, and osteoarthritis of various sites prevail in all occupational cohorts and limit the ability of patients to work.
Discussion: The severity of polyneuropathy and comorbidity status of patients from different occupational cohorts vary and this fact shall be taken into account when planning medical and professional rehabilitation of workers, which is usually hampered due to imperfection of the current regulations on examining professional suitability, according to which occupational peripheral neuropathy cases shall not stop working in conditions of physical overload.
Conclusions: It is critical to attend to the flaws of current regulations, which impede effective rehabilitation of patients with occu¬pational polyneuropathy and other associated diseases.
Razões para uma Ditadura
Authors: Prates Lucas de Souza
Published: October 2021

O presente trabalho apresenta um diálogo intertextual e metodológico com o texto de autoria de David Gomes (2010), cuja análise é feita em relação à teoria da democracia possível de Manoel Gonçalves Ferreira Filho. A proposta aqui é de apresentar o pensamento autoritário de Mário Pessoa na sua obra “O direito da segurança nacional” (1971). Para isso, é demonstrado a construção argumentativa da referida obra. Depois passa-se a revelar os paradoxos e contradições de forma crítico-reflexiva do que se categoriza como pensamento jurídico-autoritário. Essa argumentação é dada a partir da Teoria da Constituição de um viés problematizante (re)construída pelo autor Marcelo Cattoni. Utiliza-se de outros juristas da época da ditadura empresarial-militar para dar suporte interpretativo e demonstrar como o pensamento não era restrito a Mário Pessoa e Ferreira Filho. A questão é revelar como houve um efetivo esforço intelectual, de origem autoritária, na busca da suposta legitimidade do regime de exceção. A conclusão foi de que o modelo discursivo da teoria de Pessoa, bem como de outros juristas autoritários, são contraditórios, antidemocráticos, elitistas e inadequados aos projetos verdadeiramente democráticos, porém, necessários para entender a trajetória institucional brasileira. Do ponto de vista da metodologia, o trabalho tem característica jurídico-social, interdisciplinar. Utilizou-se, também, a revisão bibliográfica de caráter histórico-jurídico.
