Labor resources as a characteristic of labor potential and their structure
Authors: Toksanbaeva Mairash , Popova Raisa
Published: December 2022

One of the characteristics of labor potential is the ability to work among its carriers indiv i duals, groups and the population, by which are also studied other characteristics (demography, health, social and economic activity, professional competencies, etc.). On the basis of working capacity is determined the most general indicator of the labor potential of population, namely, labor resources. This indicator is structured according to a number of qualitative parameters. They make it possible to identify labor resources used in public production, as well as unused reserves. Their involvement in labor is becoming relevant in the context of the modern need to increase the self-sufficiency of the economy, and hence, to increase these resources. However, their growth is limited for demographic reasons. To assess the available reserves, labor resources are ranked according to the characteristics of economic activity. In descending order, the categories are distinguished according to their relation to the labor force: the real labor force (employed and unemployed), potential labor force (not employed, but willing to work) and not included in the labor force (not willing to work). Calculations for these categories showed that in 2021, the real labor force dominated in the labor force (85.6%). The potential contingent accounted for a miserable amount (slightly more than one percent), and for those who did not want to work — a little more than 10%. But among those not included in the labor force, more than two thirds of this category were those who had objective reasons for being unemployed, as well as those employed in unpaid but useful domestic work. Factors influencing the structure of labor resources are considered by regions of the Russian Federation. They showed dependence of this structure on the birth rate, aging of the population, internal migration, and, above all, on the parameters of employment and unemployment, which play a leading role among the factors for improving this structure.
Genesis and socio-economic condition of single-industry towns
Authors: Shneiderman Inna , Sharov Sergey
Published: December 2022

Crisis single-industry towns will remain in the foreseeable historical perspective an acute socio-economic problem both in Russia and in the rest of the world. The emergence of single-industry towns started in the beginning of the 18th century due to deep historical, geographical and socio-economic causes connected with development of territories and new types of economic activity, and single-industry towns themselves also contributed to emergence of social ideas and transformations. Dependence of the life of a town on one enterprise often related to the extractive sector, remote location of the town means increased risks for the socio-economic situation. In this respect, Russian cities do not differ from foreign ones. In Russia, at the official level, both the criteria for classifying settlements as single-industry towns and the methods of working with them are still evolving. The palette of solutions to the crisis of single-industry towns is well developed, but the complex nature of the problem leads to lack of ready-made solutions that guarantee success. The key point is elaborating the strategy for development of single-industry town with appropriate investment support mechanisms or, in some cases, even making a decision to close up the settlement and switch, for example, to a rotational method of work on the territory. The transition to sustainable development of single-industry towns requires coordinated efforts of all participants and stakeholders: business, local authorities and population, and significant political will of the state, while the Federation must fill in the gaps in the competence of regional authorities, if any. In this article the typology of single-industry towns and solutions is considered in the context of their genesis, the processes of transformation of modern economy and evolution in the perception of single-industry towns by society. Such approach should contribute to a more meaningful perception and decision-making leading to a long-term progressive improvement of the situation.

Authors: Alikperova Natalia , Markov Dmitry
Published: December 2022

The article is devoted to analysis of attitudes and ideas of young people about their own well-being and opportunities for implementation of financial behavior in the context of the prevailing socio-economic conditions, as well as a private assessment of these conditions and their prospects. The empirical basis of this work was the results obtained within the framework of two research projects, namely 1) research work within the framework of the State assignment for 2021 "Financial and economic culture as a parameter of the economic system: research methods and evaluation criteria" and 2) the author's sociological study "Economic culture of modern Russian youth", 2022. Youth, as the most creative and active part of society, is the driving force in the development of all spheres of society's life, and its attitude to the surrounding reality, in particular, to the socio-economic structure of our country, to the Russian elite, and the authorities sets the vector of transformational impact on both the State and society as a whole. The data obtained as a result of the conducted research reflect the negative assessments and young people's views on the future of the Russian economy and social sphere. In particular, this is expressed in low assessments of the actions of Russian elites and low trust in the State and state sources of information, that indirectly indicates that the respondents choose other sources of information for making economic decisions, and this can lead to new problems and risks associated with the quality of these sources, transformation of attitudes, values and behavior, including that in the financial market. This fact, first of all, serves as a signal to the State, which, according to the authors, should act as a conductor of all social processes in the country: economic, social, political, legal, spiritual and ideological, military, informational, environmental and others.

Authors: Egorov Nikolay , Pavlova Svetlana
Published: December 2022

The subject of the study is the socio-economic system "innovative development of region - quality of life of the population". The aim of the work is to identify the degree of relationship between the innovative development and the standards of living of the population in regions. The study is based on the application of standard methods of data collection and processing, correlation analysis and rating assessment. Official data from statistical collections and official sources of rating assessments of the quality of life and innovative development of regions were used as an information base. The analysis and evaluation were carried out on the example of the regions of the Far Eastern Federal District. The results of the rating assessment by the value of the Russian Regional Innovation Index (RRII) showed the leading positions of Khabarovsk Krai, Primorsky Krai and the Buryatia Republic. The average value of RRII in the Far Eastern Federal District is almost 2 times less than that of the leader — Moscow and is generally characterized by a low level of innovative development. According to the latest data of the Human Development Index (HDI) rating, Russia ranks 52nd among other countries of the world. The results of a comparative assessment of the subjects of the Far Eastern Federal District with the HDI levels of other countries are presented in the article. It was found out that three leaders (Sakhalin Oblast, Khabarovsk Krai and Kamchatka Krai) have higher values of the Quality of Life Index (QLI) than in Russia as a whole, and six regions of the Far Eastern Federal District are characterized by an average level of the quality of life of the population. The results of the correlation analysis showed a moderate degree of relationship between the RRI and the QLI, that allows us to use standard regression formulas for modeling predictive estimates of the impact of innovative development on improving the level and quality of life of the population in regions.

CGI-technológiával (számítógépes grafikával) készült antropomorf (emberszerű) virtuális karaktereket ma már nem kizárólag számítógépes játékokban láthatunk, hanem virtuális közösségimédia-influencerekként is, akik különböző társadalmi-politikai célú mozgalmak élére állítva üzeneteket közvetíthetnek a követői bázisuk felé, amelynek tagjai olykor paraszociális interakcióba lépnek a karakterrel. A jelen tanulmány öt olyan esetet vizsgál, amelyekben egy virtuális influencer összefüggésbe került valamely társadalmi-politikai célú mozgalommal: politikai nézetek befolyásolása; afroamerikai modellek jogai; #metoo kampány; járványmegelőzés; elektromos cigaterrahasználat. Az elemzett kampányokban megjelenő antropomorf virtuális influencerek többségére jellemző, hogy külső és belső karakterisztikájuk egyaránt kidolgozott, emberi jelleget ölt. A paraszociális interakció végbemenetele minden megvalósult kampány esetén beazonosítható.
A modernkori feudalizmus érvrendszerének kritikája
Authors: Dudik Benedek
Published: December 2022

Írásomban a 21. században a hálózatosodás hatására kibontakozó gazdasági és társadalmi átrendeződést veszem górcső alá, amely egy teljesen új gazdasági képződmény, a platformgazdaság kialakulásához vezetett. Ezzel párhuzamosan a digitális feudalizmus rendszerének kialakulása mellett szóló érveket – Jakob Linaa Jensen (2020) The Medieval Internet című könyve alapján – vizsgálom és azok relevanciáját más, a digitális gazdaságban érdekelt óriáscégek munkásságát vizsgáló tanulmányok alapján értelmezem. Jensen (2020) a Big Data rendszerek és algoritmusok korában olyasfajta alárendeltségi viszonyok megjelenése mellett érvel, szolgáltatók és azok felhasználói között, melyekhez hasonló képződmények a középkorban voltak megfigyelhetőek a feudális urak és jobbágyaik közt. Munkám során megállapítom, hogy a magánélet és személyes adataink példátlan fenyegetettsége valóban létező jelenség, viszont modern korunk és a benne megjelenő kapcsolati rendszer feudalizmussal való összevetése erősen túlzó következtetések eredménye.

PENGISLAMAN ILMU VS PENGILMUAN ISLAM: Studi Model Penerapan Ilmu Integralistik Pada Perguruan Tinggi Keagamaan Islam di Indonesia
Authors: Abidin Muhammad Zainal
Published: December 2022

This paper studies about the model of implementation of integration between Islam and science in Islamic Religious Universities in Indonesia. The transformation from State Institute of Islamic Studies (IAIN) to the State University of Islamic Studies needs the strong spirit to combine between religious knowledge and secular sciences. This spirit may be seen at the consideration clause about the policy of determination of division of sciences as found at PMA RI No. 36 Tahun 2009 which mentioned the need of the integration of the sciences performed by religious colleges. This article is the library-based paper that use the standar procedur in scientific writing. As the result of the article that there at least two models of Islamic- science integration. Both are the model of Islamization of knowledge and the scientificazation of Islam. The first one may be accomodated for the general study program that combined with the islamic value, while the other one may be accomodated for the religious studies that combined with new approach in order to more useful to answer the modernity challenges and fit with the mankind need. Both kind of models have the special advantages, only in model of scientifization of Islam more likely hoped to contribute the new original knowledge.
Cryptic Persistence of Truncated Abdominal Legs in Insects Enabled Diverse Outgrowths with Novel Functions
Authors: Bruce Heather S. , Patel Nipam H.
Published: December 2022

An iconic feature of insects is the apparent lack of legs on the abdomen, which is believed to be due to the repression of the leg-patterning gene Distalless (Dll) by abdominal Hox genes. However, in contrast to these molecular observations, it is not widely appreciated that the embryos of most insect groups do in fact form paired protrusions on most abdominal segments that appear to be homologous to the thoracic legs. However, these degenerate before hatching to form the abdominal body wall. To resolve this discordance between molecular and morphological observations, the expression patterns of pannier and araucan, genes known to distinguish proximal leg segments in all arthropods, are examined in embryos of the flour beetle Tribolium castaneum. In Tribolium embryos, all pregenital abdominal segments develop leg-like paired protrusions, and the stripes of pannier and araucan expression that delineate the proximal leg segments of the thorax are also expressed in the same configuration around these abdominal protrusions. This suggests that insect abdominal legs are homologous to only the proximal portion of the thoracic legs, which in insect adults forms the body wall (lateral tergum and pleura). These cryptic, truncated abdominal legs – likely inherited from their crustacean ancestors – appear to be an important wellspring for new functions in insects, such as caterpillar prolegs, gills, and structures for camouflage16 and aposematic warning.

Published: December 2022

Indigenous knowledge is proven to be one of the foundations of sustainable land and marine management. While indigenous knowledge is acknowledged as of important factors on maintenance of biodiversity of the planet, it also ensures the sustenance of social and economic system of indigenous community. To facilitate the application of indigenous knowledge on management of customary forest in Indonesia, since 2012, the Government of Indonesia has been providing formal access for indigenous communities to their forests to maintain forest sustainability and to enhance the welfare of indigenous community. Nonetheless, the achievement of sustainable development goals in the scope of forest and conservation area management is threatened by various competing interests and power imbalance, which mostly leads to conversion of naturally vegetated area, as well as the inability of the community to integrate new economic opportunities to its institution. Moreover, the Government of Indonesia has not been regulating the involvement of indigenous community on the management of conservation area. Most importantly, such a program provides no reference on indigenous community, especially on the assessment of authenticity of indigenous community’s forest. Cultural space methodology may fill the aforementioned gaps. The methodology was developed based on the notion of cultural space and land administration, particularly the people-and-land/marine space relationship. Moreover, such a methodology was also constructed based on the experiences of agricultural and maritime communities in Indonesia on the administration of their territories. The methodology provides a procedure to convert information on the interrelation of indigenous community, its cultural space in forest and conservation area, and indigenous knowledge into geospatial information and data that represent the cultural space unit as a geographic feature. Therefore, such methodology may be utilised to assess the authenticity of a long-existing relationship between a community, especially an indigenous one, and its land, particularly that serves conservational function.
Atmospheric CO2 Two Box Model Accurately Tracks 14C and 13C without Requiring the "Revelle Isotopic Exception"
Authors: Taylor Stephen
Published: December 2022

Although nett CO2 flows can be estimated with reasonable accuracy, the contributing gross fluxes between the atmosphere and the earth's surface are poorly understood. This paper presents a means by which the global outflow and inflow of CO2 between atmosphere and "mixing reservoirs" can be calculated, using the radiocarbon isotopes 14CO2 and 13CO2 as a tracer. It has been asserted that isotopic CO2 cannot be directly used as a tracer in flow studies because Δ14C is not subject to the Revelle factor; evidence is provided showing that this view is mistaken. The model contains 7 key parameters which are used to provide outputs of Δ14C and d13C as a function of time. By optimising the fit of these two outputs with historical records spanning 200 years or more, including during the bomb pulse, the key parameters are determined. The quality of fit of Δ14C and d13C is excellent and the internal parameters optimise at reasonable values. The global flux to and from the effective mixing reservoir, whose size is six times that of the atmosphere, is currently 58 GTC/yr in 2020, not including annually cycled carbon.
Researching Teacher Work Motivation in Ghana through the lens of COVID-19
Authors: Adarkwah Michael Agyemang
Published: December 2022

Teachers, particularly in developing contexts, were vulnerable populations during the COVID-19 pandemic. As natural parental figures for students, they had to reconcile the dual role of ensuring the safety and health of students and their own and family well-being. The external crisis of COVID-19 heightened the negative experiences of teachers in their work environments during both online and physical instruction. The qualitative phenomenological study involving thirty (30) secondary school teachers in Ghana took a comprehensive and fresh look at how COVID-19 impacted the work motivation of teachers. It was found that teachers suffered a great deal of stress in the wake of the pandemic and had face-mounting concerns about their working conditions. The low morale of teachers precipitated by COVID-19 made them develop attrition intentions. However, intrinsic and altruistic traits such as passion, the feeling of responsibility, and the desire to contribute to society and foster student development made teachers resilient towards the deleterious effects of the pandemic to promote optimal teaching. Future studies should investigate the installation of support structures that strengthen the motivation of teachers in unforeseen crises.
Novel Speech Recognition Systems Applied to Forensics within Child Exploitation: Wav2vec2.0 vs. Whisper
Authors: Vásquez-Correa Juan Camilo , Álvarez Aitor
Published: December 2022

The growth in online child exploitation material is a significant challenge for European Law Enforcement Agencies (LEAs). One of the most important sources of such online information corresponds to audio material that needs to be analyzed to find evidence in a timely and practical manner. That is why LEAs require a next-generation AI-powered platform to process audio data from online sources. We propose the use of speech recognition and keyword spotting to transcribe audiovisual data and to detect the presence of keywords related to child abuse. The considered models are based on two of the most accurate neural-based architectures to date: Wav2vec2.0 and Whisper. The systems are tested under an extensive set of scenarios in different languages. Additionally, keeping in mind that obtaining data from LEAs is very sensitive, we explore the use of federated learning to have more robust systems for the addressed application, while maintaining the privacy of the data to LEAs. The considered models achieved a word error rate between 11% and 25%, depending on the language. In addition, the systems are able to recognize a set of spotted words with true positives rates between 82% and 98%, depending on the language. Finally, federated learning strategies show that they can maintain and even improve the performance of the systems when compared to centralized trained models. The proposed systems sit the basis for an AI-powered platform for automatic analysis of audio in the context of forensic applications within child abuse. The use of federated learning is also promising for the addressed scenario, where data privacy is an important issue to be managed.
ARIMA MODEL IN PREDICTING OF COVID-19 EPIDEMIC FOR THE SOUTHERN AFRICA REGION
Authors: SHOKO Claris , NJUHO Peter
Published: December 2022

Background: Coronavirus pandemic, a serious global public health threat, affects the Southern African countries more than any other country on the continent. The region has become the epicenter of the coronavirus with South Africa accounting for the most cases. To cap the deadly effect caused by the pandemic, we apply a statistical modelling approach to investigate and predict COVID-19 incidence. Methods: Using secondary data on the daily confirmed COVID-19 cases per million for Southern Africa Development Community (SADC) member states from March 5, 2020, to July 15, 2021, we model and forecast the spread of coronavirus in the region. We select the best ARIMA model based on the log-likelihood, AIC, and BIC of the fitted models. Results: The ARIMA (11,1,11) model for the complete data set was finally selected among ARIMA models based upon the parameter test and the Box–Ljung test. The ARIMA(11,1,9) was the best candidate for the training set. A 15-day forecast was also made from the model, which shows a perfect fit with the testing set. Conclusion: The number of new COVID-19 cases per million for the SADC shows a downward trend, but the trend is characterized by peaks from time to time. Tightening up of the preventive measures continuously needs to be adapted in order to eradicate the coronavirus epidemic from the population

Published: December 2022

Background: This study investigated the efficacy of the essential oil (EO) of Syzgium aromaticum L. (clove) on the bacteria associated with otitis media. Materials and Methods: Ear swab samples were collected and bacteria isolated were identified using morphological and biochemical procedures. Essential oil was extracted from the dried flower buds using the hydro-distillation method while physicochemical and phytochemical analysis was done on the oil. Antibiotic susceptibility test and agar well diffusion was used to determine the susceptibility of the isolates to the EO. In – silico analysis was conducted to determine the drugable compound in the EO. Results: Phytochemical analysis of the oil indicated the presence of flavonoids, sterols, phenols, carbohydrates and alkaloids. Physicochemical test of the EO exhibited the presence of eugenol (80.98%) as the most abundant phytocompound. Percentage occurrence of the bacterial isolates are as follows; Proteus mirabilis (31.25%), Staphylococcus aureus (25%), Pseudomonas aeruginosa (18.25%), Proteus vulgaris (3.12%), Moraxella catarrhalis (12.5%), Klebsiella pneumoniae (3.12%) and Staphylococcus epidermidis (6.25%). Zones of inhibition were within the range of 11.5±0.71mm-23.0±2.83mm. In silico studies demonstrated that 16 out of 38 compounds identified passed the ADMET analysis. Various compounds had different binding energies, such as linalool, carvacrol for S. aureus (2NOJ), gamma-eudesmol, eudesmol for Proteus mirabilis (6H2L), eucalyptol, gamma-eudesmol and eudesmol for Proteus vulgaris (4MCX) and Staphylococcus epidermidis (4HBL). Conclusion: This study shows the potency of clove EO as an antibacterial agent and its component as potential lead molecules in drug development and design to combat multi – drug resistance.

Published: December 2022

Background: The pandemic caused by SARS-CoV-2 also caused infection in some pregnant women. Some reports say this viral infection can show symptoms of preeclampsia. Material and Methods: We analyzed 25 pregnant women with SARS-CoV-2 infection with 4 patients presenting with symptoms of preeclampsia. we performed routine blood analysis, renal function, liver function, and IHC examination to see the expression of viral proteins in the placenta. Results: we obtained 4 patients with confirmed SARS-CoV-2 infection by RT-PCR. In these 4 cases, none of the cases showed expression of the SARS-CoV-2 viral protein in the placenta, and all 4 mothers were declared dead after treatment, and 2 babies delivered out of these 4 cases died. In one case we had fetal death in pregnancy while in one case prematurity. 2 babies born to mothers with SARS-CoV-2 infection with preeclampsia were born in good condition. There were no babies infected with SARS-CoV-2 Conclusion: We conclude that SAR-CoV-2 infection in pregnant women with comorbidities can lead to a poor prognosis for both mother and baby. We cannot yet conclude whether SARS-CoV-2 infection can cause preeclampsia, but SARS-CoV-2 infection can exacerbate preeclampsia symptoms.

Background: The number of people using traditional medicines in the management of chronic diseases is increasing. The safety profile of some of the formulations, however, has not been scientifically demonstrated. This study assessed the acute and sub-acute toxicity of Uthuli Lwezichwe™ (UL), a traditional medicine used by a traditional healer in the management of diabetes mellitus.

Materials and Methods: In the acute toxicity assay, one female Sprague dawley rat was administered 1000mg/kg body weight (BW) of Uthuli lwezichwe™ and observed for 14 days. In the sub-acute assay, 24 Sprague dawley rats were randomized into four groups. With one group as the control, the other groups were administered varying daily doses (100 mg, 300 mg, 1000 mg/kg BW) of UL for 28 days. Phytochemical analysis of UL was done using Liquid Chromatography – Quadrupole Time of Flight - Mass Spectrometer (LC-QTOF-MS).

Results: There were no significant differences in liver function biomarkers and kidney function biomarkers between the control and all the treatment groups. Histological examination of the kidney however, showed enlarged bowman’s space and distal convoluted tubule diameter and area in the 1000mg/kg UL treated group compared to the control group. Similarly, histological examinations of the liver showed increased sinusoidal space and decreased central vein area in the 1000mg/kg UL treated group. A number of phytoconstituents were identified in UL.

Conclusion: The maximum safe dose was determined to be between 300 – 1000 mg/kg BW. We recommend a chronic toxicity study to assess the long-term effects.

PHILOSOPHY OF INTEGRATED NATURAL SCIENCE LEARNING
Authors: Wicaksono Anggit Grahito , Rahman Ifa Hanifa
Published: December 2022

Philosophically, natural sciences as a building of knowledge can study ontology (what you want to know), epistemology (how to acquire knowledge), and axiology (what is the value of knowledge). Natural Science as a building of science has properties that are closely related to natural objects. The problems that occur with natural objects are holistic. This holistic problem requires problem-solving from various disciplines, especially in the natural sciences. Based on the scope of the research above, this article aims to investigate integrated natural science learning in a philosophical review (ontology, epistemology, axiology). The qualitative method is applied in this study. Studies conducted to solve problems based on a critical and in-depth analysis of pertinent library materials are known as library research. Overviews of ontology, epistemology, and axiology state that integrated natural science learning, students are expected to be able to relate to other disciplines such as physics, astronomy, chemistry, geology, biology, technology, environment, and health and safety. This type of instruction uses natural science to present natural phenomena and events holistically and to develop students' problem-solving skills. The recommendation given is that teachers should tend to the interdisciplinary study of the natural sciences.

Published: December 2022

Kualitas air di Daerah Metroplotian sangatlah penting untuk diteliti karena menyangkut kelayakan dan informasi terkait penggolongan air menggunakan alat berbasis teknologi. Maka perlu diadakan sebuah kelayakan atau penelitian dalam hal ini tentang kandungan pH dan TDS yang terkandung dalam air tersebut, Di mana pH tersebut mengetahui tingkat keasaman atau basa air yang dikonsumsi itu semua tergantung pada mereka, sehingga secara tidak langsung mengkonsumsi air dengan mengetahui pH air akan memberikan informasi mengenai potensi kontaminasi, karena itu menguji pH air bisa menjadi tindakan pencegahan untuk kesehatan masyarakat. Disamping kita mengetahui pH maka kita harus mengetahu tingkat kualitas air dengan TDS air – yang mana air merupakan molekul yang paling banyak ada di alam dan sebagai sumber utama kehidupan, bahkan tubuh manusia itu sendiri. Dimana TDS (Total Dissolved solid) merupakan ukuran Zat terlarut (baik itu zat organic maupun anorganic ) yang mana TDS merupakan gambaran zat terlarut dalam Part Per Million (PPM). Penelitian ini menggunakan metode eksperimental dengan data kuantitatif melalui pengambilan sampel di 14 titik se-Kabupaten Sidoarjo. Dari hasil pengujian alat ukur pengukuran TDS dan pH meter didapatkan nilai kalibrasi dari air minum baku dibawah 300 ppm sedangkan untuk air normal dibawah 500 ppm. Untuk batasan maksimal air bisa digunakan untuk kebutuhan rumah tangga dibawah 1000 ppm. 14 titik Sampel yang telah diukur, dapat disimpulkan bahwa Daerah Sedati merupakan Daerah dengan nilai ppm terbaik untuk konsumsi rumah tangga. Namun harus diolah terlebih dahulu dalam pengkonsumsiannya dikarenakan diatas 300 ppm. Sedangkan untuk 13 titik sampel daerah selain Sedati tergolong mengandung logam dan bahan-bahan campuran dalam air. Sehingga dibutuhkan pengolahan lebih lama lagi untuk bisa dikonsumsi.

Published: December 2022

This paper presents the analytical investigation of the Fidelity and Concurrence of Photonic Quantum teleportation Circuit (PQTC) designed using quantum dot within the optical micro-cavity, considering vacuum noise and sideband leakage. It is found that the performance of the Photonic Quantum teleportation Circuit is significantly dependent on the interaction between the spin of quantum dot and photon within the optical cavity. The maximum concurrence obtained is 0.8158 at \(g/k=5\) and \({k}_{s}/k=0.1\) without noisy environment and 0.375 at \(g/k=0.3\) and \({k}_{s}/k=0.1\) with a noisy environment. The computed maximum fidelity of 0.99 is observed at \(g/k=4\) and \({k}_{s}/k=0.1\) with noisy conditions, and 0.4603 is observed at \(g/k=0.3\) and \({k}_{s}/k=0.1\) without noisy conditions. The work reported in this paper can be used to implement different quantum cryptography-based protocols.

Background
Many people in the community become infected with the coronavirus and seek help from the pre-hospital Emergency Medical Service (EMS) system. This study aimed to identify the pre-hospital medical intervention delivered to the COVID-19 patients by EMS personnel.
Methods
In this cross-sectional study, 335 EMS personnel were selected by random sampling method from the 49 pre-hospital emergency stations of east and west Azerbaijan Province, Iran. Data were collected using a questionnaire assessing the demographic characteristics and pre-hospital medical intervention delivered to COVID-19 patients. Data were analyzed using SPSS software version 21.
Results
The results showed that 68.9% of the missions for COVID-19 patients were emergency situation, and for these patients invasive interventions; Cardiopulmonary Resuscitation (CPR) (60.9%), intubation (53.1%) and suction (38.8%) were performed. Administration of oxygen, intravenous (IV) line, patients transport to emergency department, serum therapy and recommendation for home care were the most common pre-hospital medical interventions. The results showed that there was a significant relationship between the pre-hospital medical intervention with personnel’s educational degree, field of study, and history of the COVID-19 disease (P < 0.001).
Conclusions
The results showed that EMS personnel, in addition to close contact with COVID-19 patients, perform various advanced interventions for them. Therefore, planning to train these personnel, developing standards, following protocols and adequate access to personal protective equipment (PPE) and diagnostic and therapeutic equipment can be useful in improving the quality of patient care, handling of the patients and personnel safety in recent and future pandemics.
The contribution of Middle East irrigation to the growth of the Karakoram glacier

Published: December 2022

Globally, ice sheets and mountain glaciers are on the decline [1-5]. However, satellite and ground data have shown an anomalous glacier gain over the Karakoram (KK) glacier in the northwestern Qinghai-Tibet Plateau[3, 6-12]. Presently, scientific consensus has not yet been established on the causal mechanisms responsible for this glacier gain. Here, we hypothesize that this KK mass gain is possibly attributed to irrigation in the Middle East (ME) through atmospheric teleconnection (KK-ME hypothesis). First, using observations from the Gravity Recovery and Climate Experiment (GRACE) and Global Precipitation Climatology Project (GPCP), we show mass and precipitation loss in the ME but both gain in the KK. Then, we test the KK-ME hypothesis using simulated differences in precipitation resulting from the irrigation and non-irrigation cases in the Community Atmosphere Model and Community Land Model. The result suggests that ME irrigation increases the amount of evaporated moisture. The excess water vapour is transferred to the KK by the strengthened westerly water vapour transport, increasing the simulated precipitation by approximately 30% around the KK region.
