Diabetes Melitus Sebagai Faktor Risiko Tuberkulosis
Authors: Aditya Nugraha Ida Bagus , Gotera Wira , Yustin Wayan Evie Frida
Published: December 2023

Hubungan antara diabetes mellitus (DM) dan tuberkulosis (TB) adalah saling berkaitan,  karena DM tidak hanya meningkatkan risiko TB aktif tetapi juga mempengaruhi hasil pengobatan. Beban penyakit TB, terutama di negara berkembang, tetap tinggi meskipun telah dilakukan berbagai upaya pencegahan. Diabetes mellitus yang menyebabkan imunosupresi semakin diakui sebagai faktor risiko independen untuk TB. Diabetes mellitus meningkatkan risiko berkembangnya TB dua hingga tiga kali lipat dan juga meningkatkan risiko kegagalan pengobatan TB, kekambuhan, dan kematian. Diabetes juga dapat menyebabkan penyakit parah, reaktivasi fokus TB yang tidak aktif, dan hasil pengobatan TB yang buruk. Beberapa obat antituberkulosis yang biasa digunakan secara terpisah dapat menyebabkan gangguan toleransi glukosa. Skrining tuberkulosis pada penderita diabetes telah direkomendasikan, tetapi memerlukan bukti nyata mengingat efektivitas biaya dan manfaatnya.

ORIENTATION OF PLATE PARTS DURING ASSEMBLY
Authors: Cherepanov Anatoliy
Published: December 2023

The article presents an analysis of methods of logical recognition of the position and orientation of parts during assembly, which allowed us to establish that among them, pneumatic methods implemented by jet-logical orienting devices have undoubted merits. The process of recognizing the position of parts based on the theory of continuous flow of compressed air flow in the gap between the planes of the reactor and the part is considered. The use of self-powered jet sensors and jet logic elements together representing the recognition cells that create control signals by supplying a stream of compressed air into the gap between the sensor and the part using a cen-tral channel is shown. The recognition cells expand the possibilities for the orientation of plate parts, and also exclude individual channels for supplying power to each sensor of the orienting device. The advantages and disadvantages of the methods of orientation of plate parts during assembly are considered

Unraveling the International Law of Colonialism: Lessons From Australia and the United States
Authors: Miller Robert , Hobbs Harry
Published: December 2023

In the 1823 decision of Johnson v. M’Intosh, Chief Justice John Marshall formulated the international law of colonialism. Known as the Doctrine of Discovery, Marshall’s opinion drew on the practices of European nations during the Age of Exploration to legitimize European acquisition of territory owned and occupied by Indigenous peoples. Two centuries later, Johnson—and the international law of colonialism—remains good law throughout the world. In this Article we examine how the Doctrine of Discovery was adapted and applied in Australia and the United States. As Indigenous peoples continue to press for a re-examination of their relationships with governments, we also consider whether and how the international law of colonialism has been mitigated or unraveled in these two countries. While we find that the Doctrine lingers, close examination provides several important lessons for all Indigenous nations and governments burdened by colonization.

Saudi EFL Students’ Perceptions of Pedagogical Translanguaging in English Medium Instruction
Authors: Almatrafi Bakheet
Published: December 2023

The English language has been increasingly used as a medium of instruction (EMI) at the tertiary level in Saudi Arabia. Recent research has garnered Saudi students’ perceptions regarding EMI, revealing that some participants preferred a mixture of English and Arabic. Although these studies have provided valuable results, they did not expose participants to translanguaging before investigating their perceptions. Hence, this paper reports on the findings of a quantitative study that surveyed 18 Saudi college students about their perceptions of a four-week pedagogical translanguaging intervention delivered to improve their academic writing skills. The purpose of this study is to investigate the effectiveness of incorporating pedagogical translanguaging into an EMI setting. A Likert-scale questionnaire consisting of 12 items was used to collect data after which it was analyzed via SPSS. Findings revealed most participants found translanguaging useful as it made lessons and activities less challenging and more comprehensible. We suggest that teachers and policymakers adopt a flexible language use policy in tertiary education, normalizing translanguaging as a medium of instruction in EMI contexts. Implications for incorporating translanguaging as a medium of instruction and recommendations for future research directions are discussed.

Sjögren's Syndrome: A Rare Clinical Entity in Children
Authors: Hamri Laila , Saoudi Saloua , Rabhi Samira
Published: December 2023

Background. Sjögren's syndrome (SS) is a rare autoimmune disease in children, with only a few hundred reported cases. Its clinical presentation is atypical. We report the case of a 14-year-old boy diagnosed with recurrent parotitis.

Case Presentation. Our patient, a 14-year-old male, presented with a one-year history of recurrent bilateral parotid swellings. Clinical examination revealed an objective oculo-buccal dryness. Ultrasound imaging showed hypoechoic hypertrophy of the parotid glands. Anti-SSA/SSB antibodies were strongly positive. Histological study of the accessory salivary glands revealed lymphocytic sialadenitis with a focus score of 3. The diagnosis of SS was confirmed according to the ACR/EULAR 2016 criteria. The combination of treatment with hydroxychloroquine and corticosteroids resulted in the resolution of clinical signs and biological inflammatory markers.

Conclusion. Given the rarity of SS in children, several diagnostic and therapeutic difficulties arise, in the absence of classification criteria adapted to the juvenile form of the disease, and the absence of therapeutic recommendations consolidated by clinical trials in children.

Published: December 2023

A simple and rapid method has been developed for determination of lutein and β-carotene in food formulated with lutein diester beadlet, microencapsulated β-carotene as ingredients by reverse-phase high performance liquid chromatograph. This method combines extraction and saponification to one step reaction and lack of evaporation. Dimethyl sulfoxide (DMSO) was selected as solvent to release lutein diester, β-carotene from lutein diester beadlet and microencapsulated β-carotene, then add acetone-ethanol-20%KOH/methanol (10:5:4, v/v/v) to saponify lutein diester as well as extract lutein and β-carotene directly at the same time. The prepared sample solution was subjected to a HPLC analysis using Athena C30 column eluting with Methanol / methyl tert-butyl ether (MTBE) mobile phase. The precision, accuracy, linearity, specificity and ruggedness of the developed method were validated following AOAC guidance for single laboratory validation procedure. The recovery of lutein and β-carotene are 94.80%-104.76% and 98.94%-104.69% respectively. The injection repeatability: RSD(r) =1.8% for lutein, RSD(r) =5.5% for β-carotene. This method developed can be used for the quantitation of free lutein and β-carotene in products adding with lutein diester and β-carotene in quality control.

BACKGROUND

Superficial esophageal squamous cell carcinoma (ESCC) is defined as cancer infiltrating the mucosa and submucosa, regardless of regional lymph node metastasis (LNM). Endoscopic resection of superficial ESCC is suitable for lesions that have no or low risk of LNM. Patients with a high risk of LNM always need further treatment after endoscopic resection. Therefore, accurately assessing the risk of LNM is critical for additional treatment options.

AIM

To analyze risk factors for LNM and develop a nomogram to predict LNM risk in superficial ESCC patients.

METHODS

Clinical and pathological data of superficial ESCC patients undergoing esophagectomy from January 1, 2009 to January 31, 2016 were collected. Logistic regression analysis was used to predict LNM risk factors, and a nomogram was developed based on risk factors derived from multivariate logistic regression analysis. The receiver operating characteristic (ROC) curve was used to obtain the accuracy of the nomogram model.

RESULTS

A total of 4660 patients with esophageal cancer underwent esophagectomy. Of these, 474 superficial ESCC patients were enrolled in the final analysis, with 322 patients in the training set and 142 patients in the validation set. The prevalence of LNM was 3.29% (5/152) for intramucosal cancer and increased to 26.40% (85/322) for submucosal cancer. Multivariate logistic analysis showed that tumor size, invasive depth, tumor differentiation, infiltrative growth pattern, tumor budding, and lymphovascular invasion were significantly correlated with LNM. A nomogram using these six variables showed good discrimination with an area under the ROC curve of 0.789 (95%CI: 0.737-0.841) in the training set and 0.827 (95%CI: 0.755-0.899) in the validation set.

CONCLUSION

We developed a useful nomogram model to predict LNM risk for superficial ESCC patients which will facilitate additional decision-making in treating patients who undergo endoscopic resection.

Introduction. Statistical methods in the analysis of experimental data can be applied to identify patterns and test hypotheses, determine the quality of experimental data and draw conclusions based on objective data. In addition, experimental data after non-parametric processing can be used in numerical modeling using contemporary computing suites.

Aim. To outline a methodology for non-parametric processing of experimental results using SCAD computing suite tools, certified in the territory of the Russian Federation. In the proposed methodology, experimental test data for spirally reinforced concrete samples of various strengths were used.

Results. As a result of non-parametric processing of spirally reinforced concrete samples, empirical coefficients of the Prandtl bilinear diagram were determined according to the proposed method. This diagram is used in the SCAD computing suite to set the physical nonlinearity of the material behavior. A method for processing a small volume of experimental results is proposed for using the available data in SCAD CS numerical studies with an acceptable level of probability.

Conclusions. The empirical coefficients, obtained in non-parametric processing for setting the Prandtl bilinear diagram, can be used to perform a numerical modeling of the sample bahavior for planning further experimental studies in order to find more general patterns, taking into account other behavioral factors of real structural elements in load-bearing systems of buildings and structures with spiral reinforcement, including high-intensity dynamic effects. According to experimental and theoretical studies, spiral reinforcement can significantly increase the deformability and energy capacity of reinforced concrete structures, which fundamentally affects the behavioral pattern of structures and supporting framework of buildings and structures as a whole. These behavioral features of spirally reinforced structures can be further taken into account for the computational justification of design solutions in the SCAD CS and other software programs using the Padé approximation of the Prandtl bilinear diagram.

We present a deep learning method for accurately localizing the center of a single corneal reflection (CR) in an eye image. Unlike previous approaches, we use a convolutional neural network (CNN) that was trained solely using synthetic data. Using only synthetic data has the benefit of completely sidestepping the time-consuming process of manual annotation that is required for supervised training on real eye images. To systematically evaluate the accuracy of our method, we first tested it on images with synthetic CRs placed on different backgrounds and embedded in varying levels of noise. Second, we tested the method on two datasets consisting of high-quality videos captured from real eyes. Our method outperformed state-of-the-art algorithmic methods on real eye images with a 3–41.5% reduction in terms of spatial precision across data sets, and performed on par with state-of-the-art on synthetic images in terms of spatial accuracy. We conclude that our method provides a precise method for CR center localization and provides a solution to the data availability problem, which is one of the important common roadblocks in the development of deep learning models for gaze estimation. Due to the superior CR center localization and ease of application, our method has the potential to improve the accuracy and precision of CR-based eye trackers.

Published: December 2023

This article aims to articulate and empirically substantiate the concept of an efficient space for regional social development utilizing the creative potential inherent in settlement patterns. The study is built upon the author's concept of space as a set of conditions for placing material objects and that of spatial development as the region's transformation through changes in settlement patterns. An efficient space is understood as a multilayered space with smooth connections between layers forming a structure that fosters activity and intraregional connectivity. The research represents a novel perspective on the concept of intraregional connectivity and contributes to its advancement. The article describes elements, characteristics, and trends in settlement patterns, healthcare, education infrastructure, and production locations in the Komi Republic. It identifies flaws in intraregional connectivity and their root causes and uses maps to illustrate the compression of the settlement area resulting from a decrease in the number of settlements and a population outflow in the north of the region. Challenges associated with accessibility to medical institutions and lack of access to essential medical services in some areas create a risk zone for public health. The study emphasizes the transformative impact of resettlement challenges on general education institutions, necessitating adjustments in the interface between transport and social service layers. The article explores the evolving city-forming and spatial functions within such areas as Fuel-Based Arctic, Traditional North, Energy-Based Center, and Timber-Based South. It highlights the limited role of corporations and the burgeoning potential of locally focused socially-oriented companies. The findings suggest that future research areas may include the digital transformation of healthcare and education, as well as an exploration of the territorial structure of social cohesion.

Published: December 2023

Transitioning from coal to natural gas and renewable energy sources has become a global trend over the past decade. Despite efforts made by the EU, USA, Japan, and several other nations to replace fossil fuels with alternative sources, significant success in this domain remains elusive, with hydrocarbons continuing to dominate the energy landscape. Notably, the share of liquefied natural gas (LNG), once perceived as a weak alternative to pipeline gas, constituted 56 % of the global gas exports by the end of 2022, with the number of consumer countries reaching 47. This study aims to assess the potential capabilities of key LNG suppliers in increasing production and export volumes to meet the growing demand in the global LNG market. A primary focus is placed on evaluating the capabilities and plans of Russian companies to execute large-scale LNG projects. The research employs methods of systems and statistical analysis, along with economic forecasting. The article discusses the key trends in the global LNG market's development and identifies the factors exerting the most significant impact on its trajectory. An analysis of the current long-term program supporting LNG production in Russia is conducted, highlighting the key support measures available to domestic companies. The practical significance of this study lies in identifying countries poised to increase their production volumes and enter the LNG production and export arena within six to seven years. The research pinpoints key large-scale domestic LNG projects set to make the Russian LNG share in the world market grow from 8 % to 15–17 %. Subsequent steps of this research will involve assessing the prospects for selling Russian and American LNG in the Asia-Pacific (APAC) market.

The relevance of developing the construction sector in Russia stems from the imperative to 1) enhance productivity, 2) reduce costs and improve quality and safety, and 3) address future challenges such as climate change and economic diversification. This article assesses the readiness of regions for digitalizing the construction sector through a ranking system based on the geometric mean. Digitalization readiness in the construction industry is the current state of territorial socio-economic systems defined across four areas of development: the socio-economic domain, research and innovations,the digital sphere, and the industrial domain. The study aims to establish a regional ranking to assess digitalization readiness in the construction sector, with a specific focus on the Arctic zone of the Russian Federation. Regional specialization in construction-related economic activities is identified, revealing that the Yamalo-Nenets Autonomous Okrug and the Republic of Sakha (Yakutia) present opportunities for creating an industrial cluster. A benchmark ranking is proposed, indicating that the Yamalo-Nenets Autonomous Okrug and the Republic of Sakha (Yakutia) exhibit attractiveness for strategic initiatives aimed at digitalizing the construction industry.
