Authors: Elmi Abdirahman , Irekeola Ahmad Adebayo , Abdullah Muhammad Amiruddin , Mohamed Zeehaida
Published: October 2024

INTRODUCTION: Neonatal herpes simplex virus (HSV) infection is generally infrequent, despite being a life-threatening illness. Knowledge of its prevalence is limited in Malaysia since most cases are asymptomatic infections and only limited routine neonatal HSV screening is conducted. This study therefore provides a comprehensive investigation of the seroprevalence of HSV-1 and HSV-2 in neonates. MATERIALS AND METHODS: Serological screening for HSV-1 IgG and HSV-2 IgG antibody tests using the Electrochemiluminescence assay was performed on serum samples of 215 neonates delivered from January until December 2022 at Hospital Universiti Sains Malaysia. RESULTS: Of the neonates, 54.4% were found to be HSV-1 positive, while 4.2% were HSV-2 positive. All the HSV-2 neonates were co-infected with HSV-1. Newborns aged 0–10 days were the most infected group by HSV-1 (92.3%) and HSV-2 (55.6%). The most reported clinical presentation was small gestational age (SGA) (60%). Microcephaly and macrocephaly were observed in one neonate each. The clinical presentations of reactive HSV-1 and HSV-2 cases revealed the presence of fever with rash in both cases. CONCLUSION: The high seroprevalence of HSV-1 is alarming. It is hoped that these data will support the advocacy of screening women for HSV before or during pregnancy as a precautionary approach to reducing the risk of vertical transmission.

Authors: Beyaz Fatih
Published: September 2024

Bu makale, Han hanedanlığından Qing hanedanlığına kadar Doğu Asya'da uluslararası ilişkiler ve diplomasi için önemli bir model olarak Çin haraç sistemini incelemektedir. Bu sistemin bölgenin diplomatik uygulamalarını ve uluslararası ilişkilerini nasıl şekillendirdiğini araştırıyor ve haraç sisteminin hiyerarşik ancak istikrarlı ve karşılıklı yarar sağlayan bir düzen oluşturduğunu öne sürüyor. Sistemin kültürel üstünlüğe, ahlaki otoriteye ve yumuşak güce dayanması, Vestfalya düzeninin güç dengeleme yaklaşımının tersine, sık sık askeri müdahale olmaksızın bölgesel istikrara katkıda bulunduğuna değinmektedir. Çalışma, Çin haraç sistemi ile Vestfalya sisteminin ideolojik, kültürel ve pratik temellerini inceleyerek karşılaştırmalı bir analizini sunmaktadır. Çin'in hegemonik konumunu nasıl koruduğunu ve ticaret, kültürel alışveriş ve diplomatik ritüeller yoluyla bölgesel istikrarı nasıl desteklediğini vurgulamaktadır. Bu araştırma, Batılı olmayan tarihsel deneyimlerin ve teorik çerçevelerin küresel diplomasi tartışmalarına dahil edilmesini savunarak, uluslararası ilişkiler teorisinde Avrupa merkezli perspektiflere alternatif sunmaktadır. Makale, hiyerarşik düşünceyi, egemenlik ve müdahale etmeme ilkelerini vurgulayarak, Çin haraç sisteminin çağdaş Çin diplomatik uygulamaları üzerindeki kalıcı etkisinin altını çizmektedir. Haraç sistemini Vestfalya düzeniyle yan yana getiren bu çalışma, farklı kültürel ve tarihi bağlamların uluslararası ilişkiler teorisini ve uygulamasını nasıl şekillendirdiğinin yeniden değerlendirilmesini teşvik ediyor. Doğu Asya deneyiminden elde edilen içgörüler, küresel diplomasi için değerli dersler sunuyor ve alternatif uluslararası düzen modellerinin devletler arasında istikrarı ve iş birliğini etkili bir şekilde destekleyebileceğini öne sürüyor.

Authors: Yılmaz Ali
Published: September 2024

Bu araştırmada, Giresun’da 1960-1980 yılları arasında sağlık alanındaki gelişmelerin ortaya çıkarılması amaçlanmıştır. Giresun’da sağlık faaliyetleri, modern anlamda Osmanlı Devleti’nin son dönemlerinde görülmeye başlamıştır. Şehirdeki ilk hastane; 1913’te Kızılay (Hilal-i Ahmer) Hastanesi olarak hizmete girmiştir. Ardından 1917’de Guraba Hastanesi açılmıştır. Bu dönemin savaş yıllarına denk gelmesi, açlık, salgın ve bulaşıcı hastalıkların çoğalması beraberinde modern hastanelerin ve sağlık hizmetlerinin iyi koşullara doğru erişmesini gündeme getirmiştir. Bununla birlikte Cumhuriyetin ilk yıllarında, kentte kolera ile birlikte tifo, difteri, kızamık, dizanteri, verem ve frengi gibi hastalıklar da ortaya çıkmıştır. Bu olumsuz gelişmeleri önlemek için bu dönem itibarıyla kentte sırasıyla Giresun Memleket Hastanesi ve Şebinkarahisar Devlet Hastanesi hizmete açılmıştır. Giresun’da özellikle 1960 ve 1980 yılları arasında sağlık hizmetleri modern hâle getirilerek Giresun Devlet Hastanesi, Giresun Gedikkaya Göğüs Hastalıkları Hastanesi, Giresun Doğum ve Çocuk Bakımevi ve Kale SSK Devlet Hastanesi halkın hizmetine açılmıştır. Bu dönemde önemli ölçüde sağlık ocakları ve sağlıkevleri faaliyete geçmiştir. Hastanelerin yanı sıra dispanser sayıları da artmış, Ana ve Çocuk Sağlığı, Verem Savaş, Frengi ve Lepra ile Nüfus Planlaması Dispanserleri kurulmuştur. Bu sağlık kurumlarının varlığı sayesinde Giresun, Türkiye çapında sağlık koşulları bakımından önemli iller arasında yer almaya başlamıştır. Ancak bu olumlu gelişmelere rağmen ilde sağlık kurumlarında personel eksikliği derinden hissedilmiştir. Bu noksanlıklar ise 1970’li yıllardan itibaren giderilmeye çalışılmıştır. Araştırmanın amacına uygun olarak nitel araştırma yöntemlerinden doküman incelemesi yöntemi kullanılmıştır.
Antik Çağ’da Kappadokia Bölgesi’nin İnanç Sistemi Üzerine Bir Değerlendirme
Authors: Atcı Esra
Published: September 2024

Çağlar boyunca birçok medeniyete ev sahipliği yapmış olan Kappadokia bölgesi, bu özel duruma paralel olarak çok çeşitli kültürlerin doğduğu ya da şekillendiği bir alandır. Nitekim bölgenin merkezi konumu, başlangıçtan bu yana farklı etnik gruplara mensup halklar tarafından yaşam alanı olarak tercih edilen önemli bir coğrafyadır. Bu durum, başlangıçta bölgede kendine özgü bir gelişim gösteren dini hayatın giderek daha kozmopolit bir yapıya bürünmesine neden olmuştur. Bölgenin farklı alanlarında yapılan arkeolojik çalışmalar bu konuyu destekleyen en önemli verileri sunmaktadır. Bu nedenle bölgenin arkeolojik malzemelerinin sağladığı bilgiler, Kapadokya'nın tarih öncesi çağlarda bile çevre kültürlerle yakın ilişkiler içinde olduğunu ortaya koymaktadır. Bununla birlikte bölgedeki inançların ve ritüellerin başlangıç aşamasında kendine özgü bir gelişim sergiledikleri söylenebilir. Buna karşılık Kappadokia coğrafi konumu nedeniyle doğu-batı ve kuzey-güney yönlerinde uzanan yol bağlantılarının kavşak noktasında yer almaktadır. Bu nedenle zaman içinde askeri seferler, ticari ilişkiler ya da göçler gibi güçlü nedenler etkisiyle bölgedeki özgün dini yapılarda değişiklikler meydana gelmeye başlamış ve bu değişim tek yönlü gerçekleşmemiştir. Değişim ve gelişimin karşılıklı yaşandığı bu coğrafyada bulunan kültlerin sayısı ise aynı zamanda burada yer alan etnik çeşitlilik oranı konusunda da fikir vermektedir. Bu çalışmada bölgede tarih öncesi çağlardan beri tapınılan tanrıların misyonları ile bölgenin coğrafya ve iklim koşulları arasındaki yakın bağlantı, arkeolojik malzemeler, antik yazarların verdiği bilgiler ve güncel veriler harmanlanarak bölgedeki inanç sistemi incelenmiştir.

Despite the best efforts of their instructors, first-year students often misinterpret or even ignore assignment sheets, leading to unmet learning outcomes and demoralising marks. Like academic writing as a whole, assignment sheets often contain conventions, terminology, and expectations that are unfamiliar to incoming undergraduates. In this paper, I propose an activity which calls students’ attention to assignment sheets as a genre, helping them meet the practical requirements of their assignment as well as develop their genre awareness. Students work in groups to rank the major goals of their current assignment as specified in the assignment sheet and use previous student responses to consider the diverse ways in which these goals can be fulfilled. Using this exercise, students can discover the close generic and rhetorical connection between the assignment sheet and the written responses it generates, as well as the variety of successful uptakes that are possible within the assigned genre.

Published: September 2024

The adsorption of O3 molecules (ozone) on graphene, N-doped graphene, Ga-doped graphene, and -Ga-N- co-doped graphene with an emphasis on O3 detection was examined in this work. The physical characteristics of -Ga-N-co-doped graphene are significantly altered upon O3 adsorption, which makes it a suitable choice for O3 detection molecular sensors. The interaction between the O3 molecule and the adsorbent is explained on the basis of their adsorption energy, adsorption distance and charge transfer. It was found that the adsorption of ozone molecules on the -Ga-N- co-doped graphene was more favorable in energy than that on the pristine one, representing the superior sensing performance of -Ga-N- co-doped system. In our work, we estimated the charge transfer between the O3 molecule and doped graphene nanostructures based on Mulliken population analysis. The calculated adsorption energy value shows the ozone molecule more firmly adsorbs on the surface of -Ga-N- co-doped graphene nanostructures (Eads = –1.74 eV) than that of pristine graphene (Eads = –0.41 eV), deriving from a stronger covalent bond between the ozone molecule and the -Ga- N- co-doped graphene nanostructures. Our findings thus suggest that -Ga-N- co-doped graphene could be a highly efficient gas sensor device for O3 detection in the environment.

In the irradiated phosphor 4 LiRbSO Eu , the mechanisms of formation of the induced or combined electron-emitting state at 3.1-2.94 eV were studied using optical and thermal activation spectroscopy methods. It has been shown experimentally that the combined electron-emitting state of the phosphor is formed from the electron states of impurity and intrinsic electron and hole trapping centers of 24Eu SO   and 34 4 SO SO . Electron and hole trapping centers are created by irradiating the phosphor with photons exceeding the width of the forbidden band of the matrix, where free electrons are created in the conduction band and a hole in the valence band. The trapping center is formed by the capture of free electrons by impurities and anionic complexes according to the reaction 3 2 Eu e Eu      ,2 34 4 SO e SO    . In one process with electron centers, holes in the form of 24SO are localized. Thus, impurity and intrinsic 2 4Eu SO   and 34 4 SO SO  electron-hole trapping centers are formed. Similarly, trapping centers are formed as a result of charge transfer from the excited anion of the 24SO complex to the 3Eu  impurities and to the neighboring 2 4 SO anions according to the reaction ( 2 3 O Eu   ) and ( 2 24O SO  ), and localized holes are also formed in one act along with it. Combined electron-emitting states consisting of impurity and intrinsic electron states are excited by photons with energies of ~4.0 eV and ~4.5 eV.

Published: September 2024

This study focuses on the synthesis and characterization of hole transport layers (HTLs) for solar cells, particularly copper(I) thiocyanate (CuSCN) and cuprous oxide (Cu2O), synthesized via electrodeposition techniques. CuSCN and Cu2O offer promising properties for efficient charge transport in photovoltaic devices. The synthesis processes involve precise control of deposition parameters to achieve desired film morphologies and properties. Characterization techniques including scanning electron microscopy (SEM), atomic force microscopy (AFM), and ultraviolet-visible (UV-Vis) spectroscopy provide insights into film morphology and optical properties. Optimization of synthesis parameters for Cu2O films is explored to enhance their electrical properties. Photoelectric response measurements indicate improved charge separation at the interface of Cu2O/CuSCN composite films. These findings can contribute to the advancement of solar cell technology. Furthermore, the study extends its exploration to the fabrication of Cu2O by electrodeposition at different pH levels. SEM and X-ray diffraction (XRD) analyses reveal the impact of deposition parameters on film morphology and crystal structure, providing valuable insights for tailored synthesis approaches. Overall, this comprehensive study not only advances the understanding of HTL materials synthesis and optimization but also provides valuable guidance for the development of high-efficiency and stable solar cell devices.

One of the promising methods for producing ceramics from tungstate metals of the MWO4 composition is radiation synthesis using powerful electron fluxes. Due to the unique properties of radiation, it was possible to significantly accelerate the synthesis process. It has been demonstrated that ZnWO4 ceramics can be synthesized by acting on an electron flux with an energy from 1.4 to 2.5 MeV and a high power density of 10–25 kW/cm2. In this regard, studies of the optical properties of ceramic samples of zinc tungstate ZnWO4 obtained by this method were carried out. The morphology of the surface, X-ray diffraction spectra and optical properties of ZnWO4 ceramics obtained by radiation synthesis were studied. X-ray diffraction measurements and EDX analysis confirmed the formation of zinc tungstate ceramics ZnWO4 as a result of radiation synthesis. The absorption, luminescence, and luminescence excitation spectra of synthesized samples were measured. Luminescence spectra of a reference single crystal sample were also measured. X-ray diffraction confirmed the formation of zinc tungstate (ZnWO4) as a result of radiation synthesis. The luminescent spectra of the synthesized sample coincide with the spectra of crystalline ZnWO4. A comparison of the luminescence spectra of a synthesized ceramic sample and a monocrystalline reference sample measured under different optical excitation conditions shows significant differences in the luminescence spectra of the synthesized sample and the reference sample and indicates possible various defects present in the compared samples.

In the paper the results of the study on the synthesis of high-temperature superconducting ceramics of nominal composition Bi1.6Pb0.4Sr2Ca2Cu3Oy by various methods were presented based on amorphous phases using glass-ceramic technology and solid-phase method. For comparison, amorphous phases were obtained in two ways. In the first case, a heating furnace of a special design was developed to obtain an amorphous phase, which provides melting without using a crucible. The heating of the initial samples for melting is carried out due to the combined effect of the convection heat flux and the radiation of heating elements, which consists of the IR region of the spectrum at a melting temperature in the spectral range of 1300–1350 nm. In the second case, melting is carried out under the influence of broadband optical radiation, including UV, visible and IR spectral regions. The production of glassy precursors is carried out by draining the melt onto a quenching device in the form of a propeller made of stainless steel. Studies of the formation rate of the superconducting high-temperature phase Bi-2223 were carried out in the same temperature conditions at 848–850 °C with intermediate grinding every 24 hours and the study of the phase composition by X-ray diffraction method. Studies showed that the glass phase-based method ensures the completeness of the formation of the high-temperature phase Bi-2223 and the rate of its formation is significantly higher than by the solid-phase method (2.5–3 times). Studies of the critical density of the transport current have shown that the current value is 7.05×103 mA/cm2, (measured by the criterion of 1 µV/cm), which is significantly higher compared to other methods.

Valve components used in the petroleum industry are subjected to intense wear during operation, which leads to a sharp decrease in their durability. Usually, the often subjected to the wear process surface of the valves is treated by tungsten carbide cladding to improve its durability. Because of the difficulty in applying tungsten carbide using conventional surfacing techniques, high velocity oxyfuel (HVOF) spraying technology is recommended. In this work, the mechanical, tribological properties and phase composition of 86WC-10Co-4Cr composition coatings obtained by HVOF Termika-3 high-velocity gas-fuel spraying were investigated. Varying the technological parameters of spraying was carried out by changing the spraying distance, which led to differences in the thickness of the coatings. The phase composition, microstructure and distribution of elements were analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM) methods. The hardness of the samples was measured on a microhardness tester using the Vickers method, the friction coefficient and the wear rate were investigated using a friction and wear tester. It was determined that the surface of the coatings had developed character and high roughness. The results of X-ray phase analysis showed the predominance of hexagonal WC as the major phase, with a small amount of hexagonal tungsten carbide W2C as the minor phase, and the minor presence of cobalt oxide CoO. It was found that the increased wear resistance and low friction coefficient of 86WC-10Co-4Cr coatings are explained by the high volume fraction of hard and stable WC grains with high resistance to wear.

In this study, multilayer gradient NiCrAlY/ZrO2-Y2O3 coatings obtained by detonation spraying in 1D (spot sputtering) and 2D (full-surface scanning sputtering) modes were investigated. The structure of coatings was analyzed using scanning electron microscopy and electron dispersion analysis, mechanical properties (hardness, modulus of elasticity) were determined using various techniques. The tribological characteristics of the coatings including abrasion resistance and coefficient of friction were also studied. It was determined that the coatings consist of alternating layers of NiCrAlY and ZrO2-Y2O3, creating a multilayer gradient structure. It was found that the NiCrAlY layers act as a bonding element, providing interlayer adhesion, and the ceramic ZrO2-Y2O3 layer serves as a thermal barrier protecting the substrate from high temperature loads. It was found that the coatings in 2D mode have high microhardness compared to coatings in 1D mode. It was determined that the hardness of coatings smoothly increases from the substrate to the surface layers due to the gradient increase in the content of ceramic materials. It was found that coatings obtained in 2D mode have better wear resistance and lower coefficient of friction compared to coatings in 1D mode, indicating the greater efficiency of coatings in dry friction conditions and their ability to prevent wear of the substrate material.

In the article the results of a study of heat conductivity and thermal resistance of quartz-containing materials were presented. The object of the study was a quartz mineral from the Aktas deposit, located in the Ulytau district of the Karaganda region. The initial size was a piece of quartz mineral measuring 5–10 mm, which was disassembled mechanically. To prepare the samples under study, quartz powder 0.2 mm thick, crushed by the electric pulse method, was used. Electropulse technology is one of the methods based on the influence of Yutkin, accompanied by the formation of a specially formed high-voltage pulsed electrical discharge inside a volume of liquid. The pulse discharge frequency of the electrohydropulse installation for grinding the mineral to the required fraction was f = 3 Hz, the pulse capacitor capacitance C = 0.4 μF, the pulse discharge voltage U = 18–37 kV. The samples under study were made in the following dimensions: width 100 mm, length 100 mm, height 25 mm. To evaluate the thermophysical properties of manufactured samples in a stationary mode, the ITP-МG4 “100” installation was used, which determines the heat conductivity and thermal resistance of materials for thermal insulation of industrial equipment and pipelines in accordance with GOST 7076, based on the thermoelectric method, and GOST 30256, based on the thermal probe method. As a result of the study, a graph of the temperature dependence of heat conductivity and thermal resistance of quartz-containing materials was obtained. Based on the results obtained, it was established that the thermophysical parameters of the sample containing quartz are lower compared to the sample consisting of cement.

Published: October 2024

Cartap, a nereistoxin derivative from the marine annelid Lumbriconeresis heteropoda, is widely used as a pesticide, targeting pests like caterpillars. While the WHO classifies it as moderately hazardous, with a recommended daily intake of 0.05 mg/kg, human toxicity reports are limited. A 34-year-old female was admitted after consuming an unknown poison. She reported epigastric pain, burning sensations, sweating, vomiting, dyspnea, palpitations, and restlessness, compounded by alcohol intake. Initially treated for organophosphate poisoning, her cholinesterase level was 8.91. It was later confirmed she ingested 100 ml of 50% concentration cartap. Treatment included amiodarone for supraventricular tachycardia and intravenous N-acetylcysteine, magnesium sulfate, and midazolam for general tonic clonic seizure. Cartap, toxic through ingestion and skin contact, can cause symptoms such as vomiting, convulsions, and cardiac issues like supraventricular tachycardia. Supportive care is crucial, and awareness of its risks is necessary.

Published: October 2024

Introduction: Most developing regions of the world are undergoing gradual epidemiological transition resulting in high burden of both communicable and noncommunicable diseases. Morbidity and mortality pattern is a reflection of disease burden. Detailed assessment of these parameters tends to aid in formulating pivotal aspects of in-hospital policies, standards of care and so consequently promoting efficient work systems. The aim of this study is to identify the pattern of mortalities in medical wards in a tertiary care hospital.Methods: This retrospective descriptive cross-sectional study was conducted in National Academy of Medical Sciences, Bir hospital focusing on all patients admitted to the medical wards (General Medical, Hepatology, Nephrology, Neurology, Endocrinology, Pulmonology, Cardiology and Gastrology) between January 1 to December 31, 2023 after obtaining ethical approval from Institutional Review Committee (Reference Number: 390/2080/81). Total population sampling was done. Data were analyzed using Microsoft Excel and SPSS.Results: Among 10124 admitted patients in medical wards, mortality was reported in 732 (7.22%). The number of deaths seen in general medical ward was 389 (53.14%) and in liver ward was 85 (11.61%). Systemic cause of death due to respiratory diseases was 157 (21.5%) and liver disease was 143 (19.6%).Conclusions: The respiratory disease is responsible for a higher proportion of deaths among admitted patients. However, the deaths due to liver disease are increasing because of the rise in cirrhosis of the liver in the younger age group.

Hospitals require an adequate supply of blood to meet patient needs. Accurate prediction of blood demand is essential to optimize inventory management and avoid shortages or overstocks. This study aims to predict blood demand at Pelamonia Hospital using K-Means Clustering and Elbow methods. Historical data on blood demand at Pelamonia Hospital was collected and processed. The Elbow method is used to determine the optimal number of clusters in the K-Means Clustering algorithm. Sum of Squared Errors (SSE) or Within-Cluster Sum of Squares (WCSS) values were calculated for various clusters, and the elbow point on the graph of SSE/WCSS vs. number of clusters was identified as the optimal number of clusters. Once the optimal number of clusters is determined, the K-Means Clustering algorithm is applied to the blood demand data, resulting in grouping the data into specific clusters. Each cluster is analyzed to find interesting patterns or characteristics, such as clusters with high or low blood demand. From the results of the SSE calculation process on 1057 blood demand data, the result that has the biggest decrease is at k = 4 with a difference value of 2754.90. The clustering results and patterns found are used to predict future blood demand by identifying which cluster best fits the current or expected conditions. The characteristics of the clusters are used to estimate the likely blood demand. This approach provides valuable insights into blood demand patterns and enables hospitals to better anticipate blood demand, thereby optimizing inventory management and improving the quality of healthcare services.

In 2020 there were floods in the Air Hitam and Tanjung Alam villages, Bengkulu Province, and surrounding areas. These floods have caused a lot of losses to the community, especially resulting in damage to houses and agricultural land. Flooding in the Air Hitam and Tanjung Alam village areas, Bengkulu Province, occurred due to heavy rain that fell for 3 consecutive days, resulting in the overflow of the Musi Hydroelectric Power Plant (Hydroelectric Power Plant) dam which was unable to withstand the water discharge and eventually overflowed. So in this research, a prototype system for monitoring and detecting height and turbidity in embankment water in real time based on IoT will be designed. The method used is a waterfall, where the ultrasonic sensor and turbidity sensor will be connected to the ESP-8266 NodeMCU so that data on the height and turbidity of the embankment water is obtained in real-time via the user interface on the Thinger io Platform. Apart from that, the system uses LEDs in red, yellow, and green as indicators of the embankment water level. These results show that the implementation of a real-time IoT-based monitoring and detection system for height and turbidity in embankment water has good capabilities. This is indicated by the user being able to see data on the prototype system for monitoring and detecting height and turbidity in embankment water in real-time based on IoT with the display of numbers and LED indicator lights. The seawater height scale used in the system on the red LED indicator lights is 16 - 20 cm, yellow is 10 - 15 cm, and green is 0 - 9 cm.

This application provides convenience for users in monitoring and managing the coconut charcoal drying process, thereby enhancing the efficiency and quality of the final product. This integration shows excellent potential in optimizing the production process using data-driven innovative technology.
Implementation of Webservice Security: A Case Study on HTTPS Usage and ARP Spoofing Attack Threats
Authors: Fitri Novi Aryani
Published: September 2024

This study explores network security within a simulated environment built using VirtualBox, focusing on comparing the HTTP and HTTPS protocols in protecting data from eavesdropping. The research follows the PPDIOO model (Prepare, Plan, Design, Implement, Operate, and Optimize), including system requirements mapping and the setup of a virtual network environment that supports VLAN and data security. Two main scenarios were tested: an authorized user securely accesses a server using HTTPS, and another where an attacker attempts to intercept communication between the client and server using HTTP. The results indicate that HTTPS effectively protects data from eavesdropping attempts by attackers, while HTTP leaves security vulnerabilities that can be exploited to steal sensitive information. This study underscores the importance of using secure protocols like HTTPS in VLAN-based networks to protect data from eavesdropping and other threats. Additionally, the research paves the way for developing further security measures in network management, such as firewalls, intrusion detection systems (IDS), and more advanced encryption.

Published: September 2024

Artificial intelligence, as well as a number of other products of the technological revolution, served as a prerequisite for the formation of a specific area of public relations, which led to the search for adequate forms and methods of legal regulation. The use of legal resources in the process of creating the necessary regulators has led to the accumulation of relevant practical experience and the emergence of a disciplinary ontology accumulating doctrinal knowledge about the AI legal existence. The central place in it is occupied by the issue of AI legal identification, which has both theoretical and practical significance. Its development involves the development of a complex of fundamental, programmatic and design issues.
The article presents the solutions forming this complex in the context of the development of scientific legal knowledge and practice of legal regulation in the field of AI creation and use, as well as a rational view of mediation by law of the considered public relations in its current form; the author characterizes the content and dynamics of this view, analyzes the accumulated law-making experience and practice of legal experiments. The article also sets out forecasts for the further development of this segment of the legal sphere and the tools used to streamline it; defines the tasks of the legal doctrine for the future.
The article was prepared on the basis of a scientific report presented by the author at a meeting of the Presidium of the Russian Academy of Sciences on March 12, 2024.
A new approach to assessing the consequences of radiation on the eye
Authors: Ostrovsky M. A. , Feldman T. B.
Published: September 2024

The authors propose a new approach to assessing the consequences of exposure to ionizing radiation on the structures of the eye. The approach is based on the results recently obtained by the authors together with employees of the Joint Institute for Nuclear Research in Dubna, according to which radiation exposure causes oxidation of the bisretinoids contained in the structures of the eye - the retina and retinal pigment epithelium. As a result of this oxidation, the fluorescence spectrum of bisretinoids shifts to the blue region of the visible spectrum. The shift in the fluorescence spectrum can be recorded non-invasively using the method of recording fundus autofluorescence, which is currently generally accepted in ophthalmology. Since the oxidation of bisretinoids occurs during radiation exposure, it becomes possible almost immediately after irradiation to assess the degree of impact of ionizing radiation on both the structures of the eye and the body as a whole. There is no analogue to such a non-invasive assessment of the effects of radiation on the body. The proposed approach may become important for assessing the radiation safety of nuclear industry workers, astronauts, and patients undergoing proton or gamma therapy.
