De la oralidad primaria a la tercera oralidad: transformaciones culturales y cognitivas en la era digital
Authors: Cordón-García José-Antonio , Muñoz-Rico María
Published: December 2024

Las tecnologías de la comunicación han transformado profundamente la cultura y la cognición humanas, desde la oralidad primaria de las culturas ágrafas hasta la actual tercera oralidad mediada por lo digital. La oralidad primaria se caracterizaba por su inmediatez, participación comunitaria y una integración sensorial intensa, sustentada en la memoria colectiva. La invención del alfabeto fonético y la imprenta marcó el inicio de una cultura visual que promovió el pensamiento lineal y el individualismo, desplazando la experiencia sensorial integrada de la comunicación oral. En la actualidad, la tercera oralidad surge como un fenómeno híbrido que integra lo visual, auditivo e interactivo en un entorno digital global. Plataformas como TikTok, YouTube y los audiolibros no solo amplifican las características participativas de la oralidad primaria, sino que también transforman la comunicación al diluir las fronteras entre emisor y receptor. Estas tecnologías potencian una comunicación multimodal e interactiva que redefine tanto la creación de contenidos como la subjetividad humana en un marco tecnológicamente mediado. La lectura, lejos de quedar relegada, se adapta a esta nueva oralidad mediante formatos transmedia y prácticas comunitarias, convirtiendo al lector en un participante activo y consolidando un ecosistema comunicativo dinámico que combina lo oral, lo escrito y lo digital en una experiencia compartida e inmersiva.

Authors: Aktaş Özgür
Published: December 2024

This study sets out to develop the “Attitudes towards Westernization Scale”. The sample of the study was 300 students who were selected randomly and were enrolled in three departments of Education Faculty at a State University. The study utilized exploratory and confirmatory factor analyses for the data obtained, and the internal consistency coefficients were analyzed for the items (Cronbach’s Alpha) within the scope of reliability analyses. The analysis results indicated a 27-item measurement tool including the “social environment”, “adoption” and “democracy” factors. Cronbach’s Alpha internal consistency coefficients that explained 54.127% of the total variance were .87 for the total variance, .93 for social environment, .88 for adoption, and .67 for democracy. Values of the Guttman Split Half, which was calculated to have an idea about the stability of the scale or consistency between the two halves, were found .90 for “social environment”, .90 for “adoption”, and .75 for “democracy”. Fit statistics of the last modification of the model through confirmatory factor analysis were found χ2=666,87, sd=289, p

Authors: Çiftçi Türetken Pelin Saliha , Kalkan Samet , Altuğ Gülşen
Published: December 2024

Marine sediments are important reservoirs for antibiotics and heavy metals. Bacteria play a key role in polluted sedimentary habitats. This study aimed to identify heavy metal and antibiotic resistance in marine sediment bacteria isolated from Gökçeada Island in Turkiye. The samples were collected seasonally from 10 different sampling stations in 2015. Ninety isolates determined by VITEK 2 were tested against seven antibiotics using the disk diffusion method. The minimum inhibitory concentration values were measured against four heavy metal salts. The antibiotic resistance frequency rates were ordered as sulphonamides compound (93.3%), cefotaxime (78.9), ampicillin (77.8%), oxacillin (67.8%), rifampicin (57.8%), imipenem (1.1%), and oxytetracycline (0%). The heavy metal resistance ratios against ZnCl2, CuSO4, Pb(CH3COO)2, and HgCl2 were measured as 100%, 100%, 96.7%, and 73.3% respectively. The multiple heavy metal resistance index values were ranged from 0.75 (22.2%) to 1.0 (77.8%). The results show significant heavy metal and antibiotic contamination in the sediments of the Gökçeada Island. It is recommended that measures be taken against antibiotics and heavy metal pollution, as well as identifying and monitoring critical control points.

Published: December 2024

Cities are one of the main centers for the development of urban areas. The opportunity for investment activities in a city is one of the biggest pull factors for migration. Medan's rapid development can be seen from the construction of many tall buildings such as malls, apartments, and offices. The granting of permits for the construction of these high-rise buildings is closely related to urban spatial planning. Medan City does not yet have a 3D map of the distribution of high-rise buildings, there is only data on the number and location of high-rise buildings. Therefore, urban spatial mapping of high-rise buildings is needed. The model in this research uses a GIS computer model integrated in Arcgis software by taking the object of West Medan sub-district. The results of this study are the suitability of the distribution of tall buildings with a fairly dense uniform pattern in the West Medan sub-district where this sub-district is indeed a service center for trade/business, services and provincial and municipal government activities, and the economy
Chromatin diminution and its possible biological meaning
Authors: Ibraimov Abyt
Published: December 2024

Chromatin diminution (СD) is a phenomenon of germline and somatic cell differentiation during early embryonic development, associated with the loss of a portion of chromatin that represents the chromosomal constitutive heterochromatin (CH). In СD, 96-98% of chromatin is deleted in somatic cells (macronucleus), whereas in germline cells (micronucleus) they are completely preserved. Despite the fact that the phenomenon of СD was discovered in the in the late 18th century, its biological role remains to be elucidated. Numerous hypotheses have been proposed, which are the subject of discussions. Based on data obtained during the study of variability of human CH, the hypothesis of their participation in cell thermoregulation (CT) was substantiated. The essence of СT is that it equalizes temperature differences between the nucleus and cytoplasm, namely, excess metabolic heat from the cell nucleus is removed into the cytoplasm by means of a dense layer of condensed chromatin (CC) around the nucleus, consisting of CH. We discuss the view that the phenomenon of CD in parasitic animals may be related to CT in somatic cells, in the sense that in them the problem of thermoregulation is solved by the host organism and for this reason they do not need to retain full CH as the material basis of CT. Chromatin preservation in germ cells is necessary for conjugation, synaptonemal complex formation and recombination of homologous chromosomes during meiosis.

Published: December 2024

Micromeria myrtifolia Boiss. & Hohen. is a valuable medicinal plant in Türkiye, recognized for its extensive applications across the country. In this study, plant samples were collected from Muğla, Türkiye and extracts from both the aerial parts and roots were prepared using ethanol. To elucidate their phytochemical composition, a comprehensive LC-MS/MS analysis was conducted. The results revealed that both extracts were quite rich in phenolic compounds. Notably, nicotiflorin was the major constituent in both extracts (12878.31355.44 μg/g extract in the aerial parts and 47512.41311.34 μg/g extract in the roots) along with significant phenolic acids such as rosmarinic acid and caffeic acid as well as flavonoids like hesperidin. Moreover, both extracts demonstrated substantial antioxidant activities compared to the synthetic antioxidant compounds as evaluated by DPPH free radical scavenging, ABTS cation radical scavenging, and CUPRAC activity assays. Both aerial parts and root extracts also exhibited meaningful anti-glucosidase activity with 73.030.16% and 47.060.41%, respectively, at 2 mg/mL concentration. The root extract also showed moderate butyrylcholinesterase inhibitory activity. This study contributes to the existing body of knowledge with valuable insights regarding the phytochemical profile and biological activities of M. myrtifolia, paving the way for future research aimed at exploring its medicinal properties and potential uses in traditional and modern medicine.
Az utca rendje. Rendőri térfigyelés a századfordulós Budapesten
Authors: Perényi Roland
Published: December 2024

A szerző a XIX–XX. század fordulóját tekinti vizsgálata időszakának. A korabeli utcarend kialakítását az 1879-ben létrehozott kihágási törvény szabályozásaiból eredezteti. A rendőrök állandó helyen „posztoltak” ebben az időben, sokkal nagyobb közbiztonságot teremtve, mint a harmadik évezred elején. Kiváló alapot nyújt a korabeli helyzet elemzéséhez az 1902-től évente publikált „Budapesti Útmutató”, amely tartalmazta a főváros területén található összes rendőr őrszem helyét. A szerző – korabeli szabályzók felhasználásával – érzékletesen mutatja be a figyelőszolgálat feladatait, annak hatását a közterület állapotára, valamint a rendőri térfigyelés és a lakosság szociális helyzetének viszonyát. A főváros centrumából kiindulva szemlélteti a szerző a térfigyelés módosulásait a belváros és a korabeli külterületek, illetve az agglomeráció tekintetében.

A magyar állami rendvédelmi testületek katonai rendfokozati rendszerei a kiegyezéstől az ezredfordulóig
Authors: Olasz György , Parádi József , Zeidler Sándor
Published: December 2024

A magyar rendvédelmi testületek a polgári fejlődés időszakában testületi rendfokozati rendszert viseltek. Egyes testületek tagjai azonban – mint például a Magyar Királyi Csendőrség, a Magyar Királyi Koronaőrség, a Magyar Királyi Képviselőházi Őrség és a testőrségek – személyükben katonának minősültek. Ebből fakadóan ezeknél a szervezeteknél a belső függelmi viszonyok is katonaiak voltak, a személyi állomány tagjai katonai rendfokozatot viseltek. A katonai rendfokozati rendszer azonban kisebb-nagyobb módosításokon esett át, melyet végül is az eredetei katonai rendfokozati rendszerhez igazítottak. 1945. után pedig a – az orosz indíttatású szovjet minta nyomán – a teljes magyar rendvédelmi struktúrára ráerőltették a katonai rendfokozati rendszert. A magyar rendszerváltás után két évtizeddel – a nyugat-európai gyakorlattól, eltérően – napjainkban is ez a keleti ihletésű függelmi viszonyrendszer érvényesül. A szerzők a magyar rendvédelem katonai rendfokozati rendszerének a gyökereit tárják fel tanulmányukban.

BACKGROUND

A ventriculoatrial (VA) shunt is an alternative to a ventriculoperitoneal (VP) shunt for managing hydrocephalus, especially when VP shunt insertion is not feasible. Despite its decline in use, the VA shunt remains vital for certain patients. This report highlights a rare complication of bilateral vocal cord paralysis following VA shunt insertion for hydrocephalus secondary to subarachnoid hemorrhage.

OBSERVATIONS

A woman in her 60s with a history of hypertension and giant liver cysts developed hydrocephalus after a subarachnoid hemorrhage. Because of her abdominal anatomical problems, VA shunt insertion assisted by transesophageal echocardiography (TEE) was chosen. Postoperatively, she experienced sudden dyspnea and upper airway stridor, diagnosed as bilateral vocal cord paralysis, necessitating an emergency tracheostomy. Gradual improvement was noted over the following month.

LESSONS

Bilateral vocal cord paralysis can be a potential complication of TEE-assisted VA shunt procedures. To mitigate this risk, preoperative assessments of vocal cord function and swallowing are recommended. Alternatives to TEE, such as fluoroscopy or smaller probes, can be considered for patients with risk factors, including severe subarachnoid hemorrhage and prolonged intubation.

Published: December 2024

Cel artykułu ma jedynie charakter przyczynkowy, ukazując Trybunał Konstytucyjny na tle polityki. W szczególności w okresie transformacji ustrojowej, rola Trybunału Konstytucyjnego daleko wykraczała poza ramy ukształtowane w demokracji. Trybunał Konstytucyjny stał się nie tylko strażnikiem, ale często twórczym interpretatorem przepisów konstytucyjnych. Trybunał Konstytucyjny w swojej działalności uzyskał wysoki autorytet, a jednym z ważnych powodów była jego pluralistyczność pod względem politycznym, co istotnie wpływało na jego niezależność.

Na przestrzeni dziesięcioleci w różnym stopniu uzależnienie prokuratury od osób sprawujących władzę było zróżnicowane. W czasach PRL-u prokuratura pełniła wręcz rolę broni o charakterze politycznym. Ustawa z dnia 20 lipca 1950 r. o Prokuraturze Rzeczypospolitej Polskiej obowiązywała prawie 17 lat. Prokuratura w okresie po II wojnie światowej była szczególnie nasycona zmianami organizacyjnymi i funkcjonalnymi z powodu ówczesnego ustroju, jakim był PRL, gdzie upolityczniona prokuratura była użytecznym narzędziem wykorzystywanym do walki z wszelkimi formami i przejawami niezadowolenia obywateli z władzy państwowej.

Published: December 2024

Vanilla is a commodity with high economic value that belongs to the Orichidaceae family. One of the problems in vanilla cultivation is unhealthy seedlings and mother plants due to Fusarium oxysporum infection. In vitro plant propagation is an alternative because it uses a small part of the plant on sterile media so that it becomes a healthy plant. The objective of this study was to determine the effect of thidiazuron and NAA on the growth response of vanilla (Vanillaplanifolia Andrews) node explants in vitro. This research method uses RAL, which consists of two factors. Thidiazuron at concentrations of 0, 0.5, and 1 ppm combined with NAA at concentrations of 0, 1, 2 ppm. The data were analyzed by ANOVA at 5% level of significance, followed by BNT (Least Significant Difference) test at 5% level of significance. The results showed that the interaction between the administration of thidiazuron and NAA on the response of vanilla (Vanilla planifolia Andrews) nodule explants in vitro had a significant effect on the variables of shoot length and root length. In conclusion, the combined treatment of thidiazuron concentration 0.5 ppm and NAA concentration 1 ppm (T1N1) showed the best trend.

A plasticizer is a liquid added to synthetic leather materials to make the product softer, more flexible, and easier to process. The development of sustainable plasticizers in this study was achieved using palm oil as the primary raw material. The study aimed to evaluate the application of epoxidized palm oil esters on imitation leather. The epoxidation process used palm oil esters as the base material, with acetic acid, hydrogen peroxide, and amberlite resin as catalysts. The mixture was heated to a temperature of 60 °C and stirred at a speed of 400 rpm for 4 hours. The resulting epoxy oil was then applied to the top layer of imitation leather, and its mechanical properties were tested. Epoxidized palm oil esters replaced 50% and 100% of epoxidized soybean oil the imitation leather. As a control, plasticizers from commercial epoxidized soybean oil were used. The mechanical test results showed that replacing 100% of the epoxidized soybean oil with palm oil esters in synthetic leather did not result in significant differences in longitudinal tensile strength and transverse elongation compared to the control. However, artificial leather with epoxidized palm oil esters demonstrated better tear resistance than the control. Further studies are required to determine the optimal conditions for the epoxidation reaction, fatty acid composition, and stability of epoxidized palm oil esters.

Sepiolite has been used widely as nanofillers to improve the properties and compatibility of rubber blends, and due to its magnesium silicate hydrates contents, the sepiolite may also function as a thermal stabilizer. These works investigate the effects of sepiolite loadings on curing, mechanical, thermal, and morphological characteristics of natural rubber/epoxidized natural rubber (NR/ENR-25) blends. The blends were made using a two-roll mill technique using standard vulcanization reagents of sulfur and carbon black as the main filler, and their vulcanization characteristics were investigated using the rheometry technique. Furthermore, the thermal, mechanical, and morphological characteristics of the blends were evaluated using thermogravimetry, tensile tests, and electron microscopy, respectively. It was found that an increase in the sepiolite loadings decreased scorch times (ts2 and t90), whereas optimum sepiolite loading with higher tensile strength was 3 phr, which lowered down when the sepiolite loading was increased up to 9 phr. The thermogram of blend specimen with 3 phr sepiolite loading also exhibited superior thermal stability, that is, has higher degradation temperature at 5% weight loss. Fracture surface SEM photographs of the blend specimens showed finely distributed sepiolite particles at optimum sepiolite loading 3 phr and exhibited agglomerations when the loadings were increased up to 9 phr.

Aging is characterized by decreased collagen production. Collagen peptide is a hydrolyzed product of collagen. The topical peptide collagen could act as anti-aging, however, only a small concentration of peptide collagen could penetrate the skin. A microsphere is a micro-spherical particle that could increase the penetration of molecules via a transcellular pathway. This present study aims to optimize the microsphere formation of various collagen peptides as active agents, using alginate as a polymer and CaCl2 as a cross-linker. The microsphere was prepared with collagen peptide (CP), hydrolyzed collagen, CP with molecular weight (MW) < 30 kDa and CP with MW > 30 kDa. The microsphere was then characterized for its size, flowability, topography (SEM), protein-alginate interaction (ATRFTIR and DSC), drug loading, and entrapment efficiency. The molecular size of collagen peptide influences the microsphere characteristic. The higher molecular size of collagen resulted in higher microsphere size. The microsphere of CP with MW < 30 kDa has an average size of 2.25 µm (compared to native collagen with an average size of 5.00 µm). The moisture content of the microsphere is 2.27 to 3.52%. The highest drug loading was observed in the native collagen microsphere (23.85%), while the highest entrapment efficiency was also found in the native collagen microsphere (61.80%). From the SEM analysis, all the microspheres showed a sphere's shape. The fingerprint area of protein and alginate was detected in all formulations. Our study showed that the different size of collagen significantly influences the microsphere characteristics.
EXTRACTION OF THE HUMIC-LIKE SUBSTANCES FROM COFFEE HUSK-DERIVED BIOCHAR: DETERMINE PARAMETERS OF EXTRACT PROCESS
Authors: Van Phuong Nguyen
Published: December 2024

Dissolved organic carbon (DOC) with a humic acid-like composition is a very important component of biochar in agricultural production applications. DOC extraction from biochar derived from coffee husks at different pyrolysis temperatures using a KOH solution was performed. The investigated parameters of the DOC extraction process included biochar pyrolysis temperature (300, 450, and 600℃), KOH content (0.5; 1.0 and 2.0 M), homogenization speed (4000, 6000, and 8000 rpm), extraction time (1, 2 and 3h) and biochar dosage used (50, 100 and 150 g/L). The optimal extraction process parameters were determined based on the DOC extraction efficiency and the contribution of humic acid-like substances. The results showed that the optimal extraction parameters selected were biochar pyrolyzed at 300℃, 2M KOH; homogenization speed of 6000 rpm, extraction time of 2 h, and biochar dosage of 100 g/L. The DOC extraction efficiency reached 33.7% and the main components of DOC were the humic-like substance with high molecular weight. The findings in this study not only determine the optimal parameters for the extraction of organic matter from biochar but also provide a theoretical basis for the use of biochar-based extracts as liquid organic fertilizers or soil conditioners.
COMPOSITE HYDROPHOBIC PDMS-SILICALITE-1 MEMBRANES FOR THE SEPARATION OF THE ACETONEBUTANOL-ETHANOL (ABE) FROM AN AQUEOUS MIXTURE BY PERVAPORATION

Published: December 2024

One of the challenges in butanol production is its separation from aqueous acetone-butanol-ethanol (ABE) because of the azeotropic nature of the mixture and the high energy needed to recover the solvents from the dilute solution. Currently, pervaporation has been one of the most studied recovery approaches due to its selectivity when highly hydrophobic membranes are used, as well as the reduced energy demand involved in applying vacuum instead of conventional distillation. In this study, an ABE aqueous mixture was separated by pervaporation using pure and composite (mixed matrix and layered) PDMS + silicalite-1 membranes. For mixed matrix membranes, silicalite-1 crystals were dispersed in PDMS (20, 40, 60, and 80 wt%), then spin-coated using toluene as a solvent, and finally characterized by SEM-EDS, XRD, TGA, and FTIR. A total flux of 35.65 g/m2×h and a separation factor towards butanol of 22.60 was achieved with membranes prepared using 500 mg of (80 wt% + PDMS/mL of toluene) and 1,000 mg of silicalite-1 (80 wt% + PDMS/ mL of toluene), respectively. The high flux is related to the larger free volume in the polymer resulting from the incorporation of hydrophobic crystals of silicalite-1, thus improving the selectivity towards butanol. Also, the physicochemical properties of the membranes are paramount to high performance in the recovery of the ABE mixture, particularly the appropriate silicalite-1 loading.

Schmallenberg virus (SBV) infection is an infectious disease transmitted by species vectors as Culicoides sp. and characterised by fever, anorexia, decreased milk yield, loss of condition, abortion and birth of offspring with arthrogryposis hydranencephaly syndrome. The aim of this study was to determine the prevalence and presence of SBV infection in sheep in private farms in Kars province. For this purpose, blood serum samples were taken from 376 (301 females + 75 males) healthy-looking Akkaraman sheep raised in small-scale family-type farms in five central villages of Kars province (Kümbetli, Çakmak, Dikme, Subatan, Cumhuriyet) and evaluated for SBV-specific antibodies with a commercial ELISA kit. The animals included in the study were 1-4 years old. Of the sampled animals, 1.1% (4/376) were positive and 1.1% (4/376) were suspected. Seropositivity rates were determined between 0% and 2.53% according to the settlements. 1.33% (4/301) of ewes were antibody positive and all rams were antibody negative (0/75). Of the four animals with suspected antibodies, two were sheep (2/301, 0.66%) and two were rams (2/75, 2.66%). It was shown that there was no statistically significant variation in seropositivity rates amongst age groups, genders, and villages (P>0.05). This study examined the seroprevalence of SBV in sheep grown in the province of Kars. The presence of the infection was serologically demonstrated for the first time, and it was determined that the seroprevalence rate of SBV infection was low.

The paper presents a modern metallogenic overview of Rudny Altai and the results of the study of the volcanic rocks associated with contrasting basalt-rhyolite formation, manifested as a consequence of riftogenic processes. There are two linear metallogenic subzones within the Rudny Altai polymetallic belt that extend in a northwestern direction. The Zmeinogorsko-Zyryanovskaya subzone is the main one: it contains 2/3 of the belt's deposits, 3/4 of Zn, Pb, Cu, and 4/5 of Au and Ag, which are associated with Emsian-Givetian basalt-rhyolite formation. The Irtysh metallogenic subzons extends along the Irtysh Shear Zone, and is mainly composed of the Eifelian – Early Famennian basalt-rhyolite formation. Devonian bimodal volcanism occurred against a background of extension deformation with the formation of pull-apart basins. Taking into account the structure-kinematic characteristics of faults, the Devonian architecture of the Rudny Altai block can be considered as a 'negative flower' (tulip) structures. Based on the trace element characteristics of initial basic rocks, the original magmas were the product of partial melting of metasomatised lithospheric mantle. This is confirmed by Pb-Pb studies of galena monofractions from the Rudny-Altai volcanogenic massive sulfide (VMS-type) deposits. The magma source of the subsequent major phases probably corresponded to the asthenosphere, which may have risen to the depth of the preceding melting region. The generation of significant volumes of felsic volcanic series, to which the main VMS-type deposits are genetically related, was most likely associated with large-scale melting of thick terrigenous strata of the pre-Devonian palaeoshelf under the influence of mantle magmas. The sequence of Devonian mineralization types is considered to be a consequence of the change in the type of volcanism initiated by transtension tectonics. This is consistent with the concept that the formation of ore-forming systems VMS type is associated with periods of hydrothermal activity during the mantle upwelling under extensive tectonic settings. For this region, the antidromic nature of magmatic series caused a specific evolution trend of its metallogeny, expressed in the change of barite-polymetallic and polymetallic deposits of the Emsian-Eifelian stage (Zyryanovskoe, Tishinka, Ridder-Sokolnoe), pyrite-polymetallic at the Givetian stage (Belousovskoe, Talovskoe) and then copper-pyritic at the Frasnian-Early Famennian stage (Kamyshinskoe, Nikolaevskoe). The results obtained are consistent with the model of evolution of the marginal arc – back arc system, in which mantle uplift is associated with basin extension and plate rollback.

A study on the growth of the unstalked crinoid Heliometra glacialis (Owen 1833 ex Leach MS) (Echinodermata, Crinoidea) based on ring-shaped bands formed in the brachials
Authors: Stratanenko E. A.
Published: December 2024

The growth of the unstalked crinoid Heliometra glacialis was studied based on material from the northwestern part of the Barents Sea near the Svalbard Archipelago. The calculation of the crinoid age was performed using ring-shaped markings in the their brachials. The growth rings visible on the surface of the crinoid brachials were considered as annual. The most suitable mathematical model describing the growth of H. glacialis was the Gompertz equation. The averaged limiting radius of the brachials (R∞), according to this equation, was 1694 ± 119 microns, the exponential deceleration constant of the specific growth rate (g) amounted to 0.41 ± 0.04, and the maximum lifespan to 12–18 years.

Published: December 2024

We present the first results of local seismicity monitoring of the Severnaya Zemlya archipelago for the end of 2016 to 2023, recorded by a single permanent seismic station installed on Bolshevik Island. 73 local seismic events with P- and S-phases have been identified. The possibility of their sorting (earthquake or icequake) by comparing their waveforms and time-frequency analysis with regional earthquakes that occurred in the archipelago area is considered. The spatial and temporal sequence and migration rate of the events show that glacial-type events can be the result of stress discharge in glaciers under the impact of shallow crustal earthquakes within a radius of ~30 km. It is shown how, given the difficulty of deploying a seismic network, even a single permanent seismic station can provide useful information on glacial and crustal earthquakes.

Issues of legal regulation in order to ensure environmental safety, rational use of natural resources, and their protection are relevant for the Russian Federation and the member states of the Eurasian Economic Union (EAEU). FEC organizations carry out economic activities that have a direct impact on the environment. Legal regulation in the field of environmental management, the establishment of appropriate standards, environmental requirements for business activities, and the establishment of financial regulators contribute to the preservation of the environment. Issues of legal regulation in connection with the Paris Climate Agreement are of particular relevance in modern socio-economic conditions. The CIS states and the EAEU have historically established economic ties in the fuel and energy sector, and common energy markets are currently being formed. In this regard, there is a need to adopt new legislative decisions in the field of rational use of natural resources, ensuring safety and maintaining the environment in proper condition. In particular, joint solutions are needed on climate issues and economic decarbonization. In this study, the goal was to substantiate proposals for the development of certain areas of legal regulation in the area of public relations under consideration. In this regard, an analysis of national legislation was carried out, as well as interstate agreements, decisions, review documents, model laws of the CIS, international agreements and conventions were collected and analyzed. Based on the analysis, a proposal was formulated on the possibility (subject to the interest of all participants) of developing and adopting an inter-integration agreement (between the CIS and EAEU associations) in the field of activity of fuel and energy complex organizations in order to solve environmental problems, as well as climate ones. Such an agreement would allow the EAEU member states to use the existing legal potential of the CIS countries, in particular, model legislation, and would also help resolve issues of financing joint projects in the field of scientific and technical cooperation. The possibility of developing at the level of national legislation criteria for compliance with the requirements of environmental legislation and introducing compliance programs at the level of fuel and energy complex organizations (programs for compliance with the requirements of legislation on the rational use of natural resources and ensuring environmental safety) is also justified.
Codification projects of Soviet All-Union legislation (late 1920s – early 1950s)
Authors: Yashchuk Tatiana F.
Published: December 2024

The article shows the stages of codification of All-Union legislation. In the 1920s the legislation of the RSFSR was codified. After the formation of the USSR the all-Union legislation developed. At the end of the 1920s, the first ideas about the advisability of the transition to all-Union codification appeared. After the adoption of the Constitution of the USSR in 1936, drafts of the Criminal Code of the USSR, the Civil Code of the USSR, the Code of Criminal Procedure of the USSR, the Civil Procedure Code of the USSR are being developed. The process of preparation of projects and the result obtained are analyzed. The political and legal reasons for the refusal of the all-Union codification are revealed.

Motorcycles are one of the most widely used means of transportation in the community. However, this widespread usage has led to an increase in thefts, especially when motorcycles are not equipped with adequate security systems. Statistical data shows that motorcycles have the highest theft rate compared to other vehicles. To address this issue, an enhanced security system is necessary. This study proposes the use of Radio Frequency Identification (RFID) sensor and the Blynk application to provide additional security for motorcycles. The RFID system will only be accessible using the motorcycle owner's e-KTP (electronic Indonesian Identity Card) or other registered cards to start the vehicle. Additionally, the Blynk mobile application allows for vehicle control (ON and OFF) via Wi-Fi and provides real-time monitoring of the vehicle's status. This application enables motorcycle activation remotely via Wi-Fi, with a range of approximately 10 meters. Meanwhile, there is a 4-second delay to start the motor starter using e-KTP. Test results indicate that this IoT-based keyless ignition and starter system is effective in enhancing motorcycle security. With this system, motorcycles have a dual-layer security mechanism to minimize theft attempts.

Allergies are now increasingly common, due to public awareness and lifestyle changes. Although antibody tests and skin pricks can detect allergies, their accuracy is not always 100%, causing some cases of false negatives. Observing the reactions caused by food is an alternative approach, but people often forget the food they consume, especially if the allergic reaction is indirect. Therefore, tools are needed to record foods and reactions, allowing traceability to undetected allergy triggers. This study is applied research that aims to develop a prototype application for recording daily food and tracking the history of eating activities based on the allergy symptoms entered. The software development method used is the Agile method with the Scrum framework. The Scrum framework is used considering that the development of this application requires speed in its provision, and is susceptible to change, so flexibility in development is an absolute must. The software testing was conducted by User Acceptance Testing (UAT) to ensure it meets the user’s needs and requirements. The UAT results are ease of use 3.8, functionality 3.99, user interface (UI) design 3.8, utility 4, and support and help 4. UAT results indicate that the ease of use and UI design have the worst scores and need to be improved, while the utility and support have the best results.
