Beedi rolling and the health hazards associated with occupational exposure: A situational review from Karnataka, India
Authors: Rathore Ayushi , P. Ugargol Allen
Published: April 2024

Background Beedi rolling is one of the major unorganized sector activities in India and essentially employs a large number of women. The beedi industry is a labour-intensive cottage industry. The beedi is essentially a traditional form of lsquocigarettersquo and is commonly consumed by the non-affluent sections of the society. Workers engaged in the beedi rolling industry are known to suffer from many medical conditions either due to the indirect consumption of tobacco dust leading to respiratory diseases or from dermatological conditions due to the rolling process.Objectives To assess the working conditions of beedi rollers in Karnataka and to describe the occupational and health hazards that beedi rollers are exposed to and the medical conditions they are prone to developing.Methodology The study utilizes datasets on beedi workers in India especially the state of Karnataka. Data analysed for this review consists of publicly available data sources from the ILO the Ministry of Labour and Employment Govt. of India NSSO and peer-reviewed journal publications in this area.Results Beedi rollers face several health hazards and occupational exposure to tobacco during beedi rolling results in several medical conditions including musculoskeletal problems gastrointestinal problems respiratory disorders neurological disorders eye problems skin diseases gynaecological concerns cytogenic problems and blood related problems. As beedi rolling is often their only source of livelihood beedi rollers work for extended hours without realizing the harm it causes to them.Conclusion There are several beedi rolling pockets in India which serve the continued demand for this low-cost alternative to a cigarette. Longterm exposure to tobacco and poor working conditions wreak havoc on the health of beedi workers. There is a need to address the dearth of research related to tobacco cultivators and tendu leaf collectors. Research on alternative livelihoods for beedi workers needs to be undertaken and awareness of beedi workers regarding statutory benefits available under different welfare schemes needs to be improved.nbsp

Published: April 2024

A dimensão da ciência aberta intitulada de dados abertos requer ações de todos os atores da comunicação científica e os editores científicos possuem uma responsabilidade de incrementar a política editorial prevendo os requisitos mínimos para orientar os autores e avaliadores nesse processo. Por esse motivo, investigou a situação das políticas dos periódicos no campo da Comunicação e Informação quanto aos aspectos de publicação de dados científicos. Do universo de 1804 revistas no Qualis Periódicos (2016), 46 revistas do estrato A1 foram selecionadas para serem analisadas. O resultado demonstrou que 52% das revistas adotaram políticas editoriais para o compartilhamento de dados de pesquisa, no entanto, menos da metade possui orientações para autores sobre como citar e dar créditos aos dados científicos. Conclui-se que apesar da incongruência da política com as diretrizes para autores referente a citação de dados, identificador persistente e licenças uso, reuso, compartilhamento e distribuição, as revistas estão procurando acompanhar as tendências de publicações abertas.

Analysis and optimization of outputs of high power microwave tubes
Authors: Węgrzyniak Paweł , Gwarek Wojciech , Baczewski Dariusz
Published: April 2024

The subject of this work is optimization of outputs of L-band high power microwave tubes. These outputs are constructed as coaxial-to-waveguide transitions with a vacuum barrier in a form of glass or ceramic cup. The goal of optimization is to obtain sufficiently low reflection loss in the predefined frequency band and to avoid so called hot spots caused by excessive dissipation of microwave power in parts of the cup. Electromagnetic simulator has been applied to model the behavior of the optimized transition and to propose its optimum shape. The proposed solutions were verified by Z.E. Lamina SA in prototypes of high power (pulsed 600 kW) amplitrons and are to be used in manufacturing practice.
Iterative Algorithm for Threshold Calculation in the Problem of Routing Fixed Size Jobs to Two Parallel Servers
Authors: Konovalov Mikhail , Razumchik Rostislav
Published: April 2024

At present, solutions of many practical problems require significant computational resources and systems (grids, clouds, clusters etc.), which provide appropriate means are constantly evolving. The capability of the systems to fulfil quality of service requirements pose new challenges for the developers. One of the well-known approaches to increase system performance is the use of optimal scheduling (dispatching) policies. In this paper the special case of the general problem of finding optimal allocation policy in the heterogeneous n-server system processing fixed size jobs is considered. There are two servers working independently at constant but different speeds. Each of them has a dedicated queue (of infinite capacity) in front of it. Jobs of equal size arrive at the system. Inter-arrival times are i.i.d. random variables with general distribution with finite mean. Each job upon arrival must be immediately dispatched to one of the two queues wherefrom it will be served in FCFS manner (no pre-emption). The objective is the minimization of mean job sojourn time in the system. It is known that under this objective the optimal policy is of threshold type. The authors propose scalable fast iterative non-simulation algorithm for approximate calculation of the policy parameter (threshold). Numerical results are given.

Detecting Security Violations Based on Multilayered Event Log Processing
Authors: Malec Przemysław , Piwowar Anna
Published: April 2024

The article proposes a log analysis approach to detection of security violations, based on a four layer design. First layer, named the event source layer, describes sources of information that can be used for misuse investigation. Transport layer represents the method of collecting event data, preserving it in the form of logs and passing it to another layer, called the analysis layer. This third layer is responsible for analyzing the logs’ content, picking relevant information and generating security alerts. Last layer, called normalization layer, is custom software which normalizes and correlates produced alerts to raise notice on more complex attacks. Logs from remote hosts are collected by using rsyslog software and OSSEC HIDS with custom decoders and rules is used on a central log server for log analysis. A novel method of handling OSSEC HIDS alerts by their normalization and correlation is proposed. The output can be optionally suppressed to protect the system against alarm flood and reduce the count of messages transmitted in the network.

Published: April 2024

Because of the decision, taken during the ITU WRC-07, to allocate the upper part of the so-called digital dividend spectrum for mobile services on a co-primary basis with TV broadcast services, the involved stakeholders have a great interest in avoiding any interference caused by signals transmitted in adjacent bands. In this context the paper presents some experimental results of a study addressed to assess the effects produced by an interferential LTE signal transmitted from a user terminal when it is in proximity of a television antenna that receives DVB-T signals. The study has been conducted in the context of collaboration between Fondazione Ugo Bordoni and ISCTI, the scientific and technical body of the Italian Ministry of Economic Development, using high professional laboratory equipments and considering different experimental simulation test setups. Several simulation scenarios have been analyzed and results in terms of protection ratio and protection distance have been carried out.
Quantifying the Suitability of Reference Signals for the Video Streaming Analysis for IPTV
Authors: Hoppe Christian , Manzke Robert , Rompf Marcus , Uhl Tadeus
Published: April 2024

IP networks are indispensable nowadays and they are some of the most efficient platforms. The constantly growing number of users and new services in these networks – the largest being the Internet – require a satisfactory quality of service from any application they use. So, determining the QoS in real-time services is particularly important. This work shows how to quantify the suitability of reference signals for analyzing the quality of video streaming in IPTV. The assessment relies on two different algorithms: PEVQ and VQuad-HD. Three different reference signals – two real ones and an artificial one – are used in this study, and a numerical measurement system is used, which simulates mean network impairments. These measurements provide valuable information for determining the QoS of actual IPTV services in practice.
Call Blocking Probabilities of Multirate Elastic and Adaptive Traffic under the Threshold and Bandwidth Reservation Policies
Authors: Moscholios Ioannis D. , Logothetis Michael D. , Boucouvalas Anthony C. , Vassilakis Vassilios G.
Published: April 2024

This paper proposes multirate teletraffic loss models of a link that accommodates different service-classes of elastic and adaptive calls. Calls follow a Poisson process, can tolerate bandwidth compression and have an exponentially distributed service time. When bandwidth compression occurs, the service time of new and in-service elastic calls increases. Adaptive calls do not alter their service time. All calls compete for the available link bandwidth under the combination of the Threshold (TH) and the Bandwidth Reservation (BR) policies. The TH policy can provide different QoS among service-classes by limiting the number of calls of a service-class up to a predefined threshold, which can be different for each service-class. The BR policy reserves part of the available link bandwidth to benefit calls of high bandwidth requirements. The analysis of the proposed models is based on approximate but recursive formulas, whereby authors determine call blocking probabilities and link utilization. The accuracy of the proposed formulas is verified through simulation and found to be very satisfactory.

Published: April 2024

Traditional Chinese medicine (TCM) has been passed down for more than 2,000 years. TCM beauty products driven by the principles of identification and treatment with various dosage forms and exhibit mild and safe efficacy are bound to become a main component of the beauty industry in the future. Xu once commented that “Qian Jin Fang” is different from the traditional prescription system, which emphasizes the use of medicines. In this paper, we mainly selected the prescriptions for the treatment of disfigurement diseases such as acne, scarring, black dryness, face hyperpigmentation, black mole, and rosacea from the article titled, “Upper Seven Orifices Disease - Facial Medicine IX” in the Bei Ji Qian Jin Yao Fang [1]. By studying and analyzing the original composition of the formula, understanding the etiology and pathogenesis of the disease, and exploring the characteristics of the formula concerning the efficacy of TCM, their properties, flavors, and meridians, we summarized the characteristics of the Qian Jin Fang. It is based on the external treatment of disfigurement diseases, with a wide variety of drugs, flexibility, and accuracy. This method draws upon analogies while utilizing excipients and harmonizers to focus on the combined healing approach of treatment and nourishment.

We prove that for each u ⩾ 2 the class of all single-valued Σ0 ucomputable numberings of any infinite family of total functions is effectively infinite and the class of all its Σ0 u-1-computable numberings is generated by the downward closure with respect to the reducibility of the set of all infinite direct sums of uniformly Σ0 u-1-computable sequences of its single-valued numberings. It is established that if u > 2, then the class of all Σ0 u-computable numberings of any infinite family is generated by infinite direct sums of uniformly Σ0 u-computable and uniformly Σ0 u-minimal sequences of its numberings.

Alzheimer's Disease (AD), a form of dementia prevalent in older age, is a neurodegenerative condition impacting brain nerve cells. Early-stage AD symptoms are often subtle, complicating timely diagnosis. Early detection allows for intervention, slowing disease progression and facilitating appropriate treatments. Deep learning methods, particularly gradient-based images, prove promising for early Alzheimer's detection in Magnetic Resonance (MR) imaging. Gradient-based images, highlighting details in low-intensity images and enhancing contrast, play a vital role in determining structures' location, shape, and size, notably in techniques like Magnetic Resonance Imaging (MRI). This study aims to boost model performance in early AD detection by applying the Gradient filter before training deep learning models on diverse-angle and constant-density brain MRI images. The dataset comprises three categories representing early-stage AD, including images of mild cognitive impairment and healthy individuals. Original and gradient-filtered image subsets were inputted into deep learning models. Results indicate superior performance of gradient-based images, with the Densenet201 deep learning model achieving the highest accuracy at 98.63%.

Published: April 2024

During the first year after myocardial infarction, coronary artery restenosis, fatal arrhythmias, hospitalization for heart failure or cardiac death may occur. It is necessary to search for biomarkers to predict complications of myocardial infarction. As such predictors, it seems promising to introduce the ABCDE-SE echocardiographic protocol, as well as study the metabolism of vitamin D and proteins of the fibrinolysis system. Cardiospecific microRNAs-21, -29, -143 can be used as pathogenetic factors in the development of complications; it is proposed to study the ongoing pharmacotherapy and patients’ compliance with it as controllable factors.

Aim: To search for predictors of complications of myocardial infarction based on the assessment of echocardiographic parameters, vitamin D metabolism, components of the fibrinolysis system and cardiac-specific microRNAs.

Material and Methods. The PROMETHEUS study is designed as a prospective, open-label, non-randomized cohort study. It is planned to include 300 patients newly admitted to the vascular center with a preliminary diagnosis of ST-segment elevation ACS. All patients will have their vitamin D concentrations determined; genetic variants of polymorphisms of the vitamin D receptor gene and vitamin D binding protein; concentrations of urokinase and soluble urokinase receptor; microRNA-21, -29, -143, as well as echocardiography using the ABCDE-SE protocol at 1, 3, 6 and 12 months from inclusion. Pharmacotherapy will be assessed at all stages.

Expected results: Based on the results of the study, a comprehensive algorithm for optimizing the prediction and prevention of complications of myocardial infarction will be developed and introduced into practical healthcare.

Published: April 2024

Background: Staphylococcus aureus is a prevalent pathogen causing both nosocomial and community-acquired infections worldwide. The emergence of methicillin-resistant Staphylococcus aureus (MRSA) due to the acquisition of mecA and mecC genes poses a significant clinical challenge. The injudicious use of clindamycin for treating MRSA has led to the development of clindamycin resistance. This study aimed to determine the prevalence of inducible clindamycin resistance (iMLSB resistance phenotype) in Staphylococcus aureus isolates, employing the D test according to CLSI guidelines, particularly focusing on erythromycin-resistant strains.
Methodology: A total of 147 Staphylococcus aureus isolates were subjected to antibiotic susceptibility testing using the Kirby Bauer disc diffusion method. The D test was employed to identify inducible clindamycin resistance.
Results: The study revealed that 34% of isolates exhibited inducible clindamycin resistance, 40% demonstrated constitutive resistance, and the remaining 26% exhibited the MS phenotype. Notably, inducible clindamycin resistance was more prevalent in MRSA (40%) compared to MSSA (22%).
Conclusion: The findings underscore the importance of incorporating the D test as a mandatory procedure in standard disc diffusion testing to accurately identify inducible clindamycin resistance. This knowledge is crucial for guiding appropriate antibiotic therapy in the face of increasing resistance patterns.

This study examines the economic relevance of Henry David Thoreau’s philosophy and his quest for a simplified lifestyle in the context of the 21st century. Amidst the complexities of a globalized economy and the relentless pursuit of growth, Thoreau's wisdom serves as a catalyst for a critical reflection on economic ideologies and their impact on society. The study explores the complex interrelationships between money, education, and employment, challenging the narrow view that links education only to financial gain. Thoreau's call for a simple lifestyle, exemplified in his work "Walden," is analyzed in the light of contemporary research that highlights the tangible benefits of embracing simplicity for individual well-being, economics, and environmental sustainability. Additionally, the study explores the role of advertising in shaping consumer preferences, emphasizing Thoreau's call to reevaluate our needs in the face of widespread consumerism. Finally, the concept of a return to interdependent societies that prioritize self-sufficiency and social support is explored, drawing on historical examples and contemporary trends consistent with Thoreau's vision. Thoreau's philosophy provides valuable insights and guidance for navigating the challenges of the 21st century, overcoming materialism and economic dependence and promoting a more meaningful and sustainable way of life.
