Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Yurchenko I. F.
Published: April 2023

The need for irrigated agriculture in the Republic of Crimea is due to the natural and climatic conditions of the territory, which are characterized by a moisture defi cit with a high level of heat supply. The purpose of the research: an analytical assessment of the current state of irrigated agriculture in the Republic of Crimea and the success of its further development and reproduction, taking into account the natural resource potential of the territory and the existing experience of positive and negative approaches to the use of irrigated lands. The object of research is the crop production system of the agro-industrial complex, the subject of research is agricultural production on irrigated lands. The research material was the data of statistical reporting of agricultural and water management organizations of the republic; publications on the results of theoretical study and practice of the use of reclaimed lands, which are in the open press; as well as the author’s own work. The methodological basis of the research was: information-analytical, systematic and comparative approaches; analysis, generalization and synthesis of the obtained data; statistical, expert and heuristic evaluations. The analysis of the development and effi ciency of agricultural production on the irrigated lands of the republic revealed signifi cant shortcomings in their use. Of the total area of irrigated land, about 24 thousand hectares are irrigated, i.e. no more than 5%, which is associated both with limited water resources and with depreciation of 80% of fi xed assets, lack of necessary sprinkler equipment, understaffi ng of pumping stations, etc. It is shown that the natural resource potential of the territory is not fully realized. The average yield of cereals and leguminous crops under irrigation can exceed the actual one by 1.5-2 times. An increase in the area of irrigated lands with unsatisfactory indicators of alkalinization has been established. The priority measures for rational water use in the reclamation sector of the economy of the Republic of Crimea are presented, including a set of measures f or the effective use of water resources of the territory, taking into account economic, social and environmental components. Its implementation is necessary regardless of the renewed supply of Dnieper water to the North Crimean Canal.

Currently, there is a situation where the funds for maintaining the engineering reclamation systems in working condition are used rationallyenough. One of the reasons is the low level of elaboration of the goals and objectives of the repair or reconstruction of structures, ignoring the requests of organizations directly involved in the operation of hydromelioration systemsand interested in regular, sufficient and safe water supply. The question of choosing how to restore objects is of paramount importance. On each hydro-reclamation system, a detailed analysis can identify the so-called «bottleneck», the elimination of which, which requires relatively insignificant costs, can signifi cantly increase the productivity of the HMS. An algorithm for analyzing HMS has been developed in order to identify the causes of changes (decreases) in the operational reliability and performance of the system that arose during operation. It has been established that the algorithms for analyzing HMS, generally similar in structure, differ depending on the type of irrigation, the structure of the irrigated areas and the water consumption of the crops grown. In conditions of a shortage of financial resources, in order to increase the productivity of the system, instead of major repairs or reconstruction, it is sometimes possible to limit the elimination of only a part of the problems that are part of the work during the current repair of reclamation facilities. Such problems, which are a «bottle neck of production», in each individual case are determined by a thorough analysis of the work of the HMS. These actions do not eliminate the need for major repairs or reconstruction, but they make it possible to operate the HMS with acceptable performance during the period preceding the repair. The developed algorithm was used in the analysis of a specific object (channel R-3, Maloderbetovsky and Oktyabrsky district of the Republic of Kalmykia) and showed high efficiency.

Published: April 2023

The aim of the work was to solve the problem of increasing the efficiency of identifying large enterprises that pollute natural water from among many water users of the industrial region. For this purpose, artificial neural networks (INS) were used to detect and evaluate the weights of connections between statistical data, which is important for studying the dynamics of water quality formation in conditions of its spatial and temporal variability. The work was carried out on the example of the available 250 measurements of the concentration of each of the four priority metals at the hydro chemical gates of the Iset River in the area of Yekaterinburg. Neural network analysis made it possible to detect the interdependencies of individual water quality indicators at neighboring sites. At points above Yekaterinburg (+5.2 km, target 1), in the city (target 2) and below it (–4 km, target 3), in total at 3 × 4 × 250 = 3000 points. It was found, in particular, that the effect of the nickel content in the water of the gate 2 on the concentration of other metals of the gate 3, especially zinc, is quite high, so that the correlation coefficient is not lower than 0.6. Such results made it possible to identify the logistical economic ties of water users and simplify the identifi cation of water pollutants by the “water footprint” left by related enterprises. Thus, it is shown that the INS provides the identification of a man-made decrease in water quality against the background of its natural pollution with the same substances. The reliability of the conclusions is confirmed by the ability to satisfactorily predict the water quality of the section located downstream of the river, according to the data for the section located above, as established in the work by predicting water quality using the INS.

Cultural Significance of Seiwansawa Written by Oeda Ryuho in History of Japanese Senchado
Authors:   The Korean Tea Society, Kim Dae-Young
Published: April 2023

Seiwansawa, the book written by Oeda Ryuho is the first specialty publication of Senchado in Japan. He lived as a hermit in Kyoto and Osaka and lived as a man of taste, leaving various books on the elegant hobbies of literary taste, including incense burning. It was Seiwansawa that the publisher edited and published a separate article about infusing tea written during his lifetime. The publication of this book suggests high interest in the new method of making tea, infusing tea of intellectual in Japan at the time. He described his thought of infusing tea by quoting a number of Chinese references. Rather than accepting a large number of Chinese literature as it is, he added his views by adopting them analytically based on his experience and preferences. His though of infusing tea, which was revealed through the book, aims to inspire grace by recognizing infusing tea as one of the elegant hobbies of literati. His view of tea inherited Baisao's view by retrospecting the spirit of tea to Lu yu and Lu Tong, the literati of Tang period, but he considered pleasure rather than performance. This pursuit of elegant and pleasure improved the uniqueness and professionalism of the method of infusing tea, and his view of tea could be followed by Ueda Akinari and other later literati tea lover.

Published: April 2023

The United Nation (UN) lists ending poverty in all its forms as the number one prerogative among seventeen sustainable development goals. One organization that is seeking to make an impact on those who live in poverty is Heifer International, a global nonprofit organization based in the United States, whose mission is “to end world hunger and poverty while caring for the Earth.” By using Values-Based Holistic Community Development, Heifer has helped to lift millions of people out of poverty. In this article, we present the results of a study we conducted in Bihar, India to assess the impact of Heifer International programming on participants’ communication competency. Grounded in over 100 interviews with women across four time periods, the results show that women who have partnered with Heifer International experience significant qualitative changes in communication competency across five areas: expressiveness, assertiveness, persuasiveness, openness, and positiveness. We discuss the implications of this work on communication competency and empowerment for women living in poverty and its impact on personal transformation. 
Predictive role of culture-based MIC testing vs. genotyping for carbapenem-resistant Enterobacterales in a non-universal screening, highly resourced setting
Authors: Alnimr Amani M
Published: April 2023

A lack of evidence of accuracy for various testing modalities for carbapenem-resistant Enterobacterales (CRE) reduces the efficiency of screening and delays the isolation of carriers. This study examined the performance of phenotypic detection of CRE in comparison to molecular testing. A cross-sectional study was conducted in an academic medical institution in Saudi Arabia on CRE-screened patients during a 36-month period (April 1, 2019, through March 31, 2022). Cases were followed up for their susceptibility status by the phenotypic gradient method and genotypes. Of 3,116 samples tested, 359 carbapenemase genes were detected in 297 strains (9.5%) belonging to 292 patients. Oxacilliniase-48 (OXA-48) was the most frequently detected genotype (n=190, 64%), followed by a combined New Delhi metallo-B-lactamase (NDM)/OXA-48 genotype (n=77, 25.9%). Variable missed isolation days were encountered for various genotypes (0-18.5 days), with an excellent clinical utility index obtained for screening the OXA-48 genotype phenotypically. The data provided some insights into the predictive role and shortcomings of the e-test alone in CRE screening. While it provided a reasonable approach in a CRE population dominated by OXA-48 genotypes, it was more likely to miss the NDM-incurred carbapenemase. Thus, local epidemiology in an institution must be considered when designing a local screening protocol in addition to consideration of cost and turnaround time.

Background: To determine the association between coronavirus disease-2019 (COVID-19), medical attention and self-care of patients with type 2 diabetes (T2DM) at the Archbishop Loayza National Hospital.

Methods: This analytical cross-sectional study, involved interviewing 181 T2DM patients and recording their actions regarding three aspects–self-care measures, medical care, and spending on medicines–before and during the pandemic. The relationships between the variables were established using descriptive and analytical statistics.

Results: During the pandemic, self-care decreased to 37%; 26% had access to medical care. Patients in the provinces experienced better self-care (Lima: 35%; Provinces: 61%; p=0.002). Patients with comorbidities also took good care of themselves (with comorbidities: 41%; without comorbidities: 29%; p=0.036).

Conclusions: COVID-19 had a negative influence on T2DM patients regarding self-care and medical care. One out of four patients received medical care. Additionally, being outside Lima and having comorbidities were associated with better self-care during the pandemic.

Aim: Prolonged use of electronic devices (EDs) and adopting poor posture during ED usage might lead to musculoskeletal disorders among young adults and adolescents. Hence, this study compares neck muscle strength, range of motion (ROM), and craniovertebral angle (CVA) among Malaysian young adults using different EDs.

Methods: A cross-sectional study using a quantitative study design was applied to compare neck muscle strength, ROM, and CVA between laptop and tablet users of Malaysian young adults. The population of this study covers young adults residing in Selangor, Malaysia. Among them, 30 laptop users and 30 tablet users were selected using the selection criteria and criterion-based sampling method. The data analysis was carried out with SPSS 20.0 at a 5% level of significance.

Results: There was no significant difference between the laptop and tablet users concerning neck muscle strength and CVA. However, a significant difference was observed only in the neck extension ROM between laptop and tablet users. The mean neck extension ROM is lower in tablet users than in their counterparts. The mean CVA of laptop and tablet users was less than 50 degrees, indicating severe FHP. Most laptop users (73.3%) were categorized into severe FHP than tablet users (53.3%).

Conclusion: The mean neck extension ROM is lower in tablet users than in laptop users. Most laptop users had severe FHP than tablet users. Hence, Malaysian young adults should adhere to the appropriate duration of ED usage, ergonomics while using ED. and postural correction exercises to prevent and reduce musculoskeletal problems.

Published: April 2023

This paper is part of a project on enhancing STEM teaching through teachers’ professional development (TPD). The aim is to explore K-12 science and mathematics teachers’ views and practices about implementing STEM through technological pedagogical content knowledge (TPACK) model in Qatar and identify their challenges. The objective is to develop a TPD program using project-based learning pedagogical intervention to support K-12 science and mathematics teachers and to train them on how to implement PBL in their teaching practices. 245 STEM teachers from 16 preparatory and secondary schools, representing an equal number of males and females, responded to a STEM-TPACK survey on perceptions of and practices in teaching STEM subjects. One hundred thirty-seven preparatory (grades 7-9) and 108 secondary school teachers (grades10-11). Generally, there are no significant differences between the different dual groups in understanding STEM, TPACK, and embedding technology, with few exceptions in some aspects. This reflects a high consistency in teaching, pedagogy, and learning environments among these groups (gender, teaching level, and STEM subjects taught). Preparatory school teachers show more variations in all elements of TPACK than secondary school teachers, as reflected by values of standard errors of the mean (SEM). Male teachers show slightly more understanding of elements of TPACK and have somewhat higher means than female teachers. SEM for female teachers is slightly higher, indicating more variation among female teachers than male teachers. However, the difference is also insignificant, as characterized by the small effect sizes ranging from 0.13 to 0.31, small t-test values, and high p-values.

Culex quinquefasciatus and Cx. tritaeniorhynchus are 2 dominant disease vectors in Neijiang City, Sichuan Province, China. Although there is evidence of confirmed resistance against insecticides in mosquito vectors, nothing is known about the existing insecticide resistance-conferring mutations in Cx. quinquefasciatus and Cx. tritaeniorhynchu in this region so far. In this study, the G119S mutation in the acetylcholinesterase (AChE) was detected in Cx. quinquefasciatus at a very low frequency (0.9%) with no resistant homozygotes being observed. Two resistance mutations in the voltage-gated sodium channel (VGSC) (L1014F and L1014S) were found in Cx. quinquefasciatus with frequencies of 88.7% and 8.3%, respectively. By contrast, the AChE F455W mutation was found to be fixed (with a frequency of 100%) in 3 of the 5 studied populations, with an overall frequency being 98.1%. In addition, 1 resistance-conferring VGSC mutation (L1014F) was detected with an overall frequency of 15.2% in Cx. tritaeniorhynchus. These results indicate that the well-recognized insecticide resistance-conferring mutations in both AChE and VGSC are present in the 2 Culex species in Neijiang. The contrasting patterns in the frequency of resistance alleles indicate that species-customized strategies of insecticide resistance management should be considered for the 2 species.

A Doppler Location Method Based on Virtual Path Difference
Authors: Tao Yu
Published: April 2023

This paper presents a Doppler passive location method for moving targets with fixed single station using the Doppler frequency shift and time difference information. First, based on the relationship between frequency shift and path difference, the virtual path difference is calculated from the measured value of Doppler frequency shift by means of mean value correction. Then, under the assumption that the target is moving at an average speed along a straight line, two coaxial virtual double base arrays are constructed by using the moving track of the moving target based on the method of fixed period time difference. On this basis, the moving distance of the moving target can be calculated by using the ratio relationship between the frequency difference and the radial distance between the two adjacent detection points in the middle of the array, and the linear solution of the two double base path difference positioning equations. At this point, the relative coordinate position of the moving target can be obtained by directly using the linear solution of the double base path difference positioning equation again.

About the feasibility to realize a nonlinear radar with processing at the probing signal frequency

The conditions for the implementation of a nonlinear radar using a probing signal having a form as a periodic sequence of pairs of radio pulses with different amplitudes and equal energies, are considered. The energies of the reflected pulses are compared in the locator receiver for each pair, which makes it possible to detect reflections from nonlinear devices at the probing signal frequency by violating the equality of these energies. A numerical experiment was performed to evaluate the dependence of the current form through germanium and silicon diodes and their amplitude parameters at the frequency of the acting sinusoidal voltage with variable amplitude. As a result, it was found that the amplitude nonlinearity can be detected before the diode is completely "opened" if the two voltage amplitudes on the diode differ from each other by at least one and a half to two times. Since the pulse energies are proportional to their powers, and the pulse durations are unchanged, it should be possible to detect non-linearity by determination of a ratio between the radar cross-sections of non-linear objects for different pulse amplitudes. To obtain quantitative estimates, a simulation of the incidence of a flat, linearly polarized wave on a half-wavelength dipole and a half-wavelength folded dipole loaded with a diode was performed. It was found that the model type and parameters significantly affect both the values of the radar cross-sections and the degree of influence of nonlinearity on these values, so that the detection of non-linearity requires significantly higher power levels of the probing signal than the theory predicts.

Pakistan’s National Educational Policy 2009 delineates that quality of teacher certifications in primary and secondary tiers of education willprogressively be made more rigorous by replacing the erstwhile Primary Teaching Certificate (PTC) and Certificate of Teaching (CT) programs. For this and similar policy provisions, in the last two decades, Pakistan has witnessed a rapid increase in the number of private and public Teacher Education Providers (TEPs) that provide alternate and supposedly more rigorous certifications such as the Bachelor of Education. As a result, struggles have ensued among the TEPs to bag their market share of thepotential applicants to their teacher education programs. T

Published: April 2023

The effect of refrigerant injection techniques on the performance of heat pump system based on exergy analysis was studied theoretically. Three refrigerant injection techniques were used; the first was achieved by injected vapour in volume ratios from 1 to 7% in the accumulator. The second was injection liquid refrigerant in the discharge line with the aid of Liquid Pressure Amplification (LPA) pump, with volume ratios from 1 to 10%. The third was a hybrid injection with volume ratios of injected vapour and liquid varied from 1 to 3% and 1 to 10%; respectively. The following improvements in cycle performance were observed. For vapour injection technique, the best ratio of injection was 5%, the exergy destruction reduced by 21% and exergy efficiency enhanced by 14.6%. For liquid injection technique the best ratio of injection was 6%, the reduction in exergy destruction was 34% while the exergy efficiency increased by about 21.4%. The hybrid injection technique increased the exergy efficiency by 23% when the volume ratio of vapour and liquid injections are 3% each. The effect of condensing pressure on the cycle performance was studied also. The optimum exergy efficiency of the cycle was 54.55% achieved when the condensing pressure was 15 bars.

Authors: Alasadi Ali Abdul Mohsin Hasan , Habeeb Ahmed Khalid
Published: April 2023

The effect of air injection angle on the performance of airlift pump used for water pumping has been studied analytically and experimentally. An airlift pump of dimensions 42mm diameter and 2200 mm length with conventional and modified air injection device was considered. A modification on conventional injection device (normal air-jacket type) was carried out by changing injection angle from 90  (for conventional) to 45  and 22.5  (for modified). Continuity and one-dimensional momentum balance for the flow field with basic principle of two-phase flow and expressions of slip ratio and friction factor as function of flow rates were formulated. The analytical and experimental investigations were carried out for both conventional and unconventional air-jackets at submergence ratios 0.75, 0.6 and 0.5 and air mass flow rate from 0.5 to 97kg/hr. The comparison between the analytical and experimental results shows agreement and the main results showed that the performance and maximum efficiency of airlift pump is increased for higher mass flow rate of injected air for all tested submergence ratio using unconventional air-jacket and the higher performance was associated with injection angle 22.5 , with average enhancement were 9% and 10% for performance and maximum efficiency respectively.
Robustness Assessment of Regional GNSS Geodetic Networks for Precise Applications
Authors: Alhamadani Oday Y. M. Zeki , Khalaf Ahmed Zaidan
Published: April 2023

Over the past few decades, the surveying fieldworks were usually carried out based on classical positioning methods for establishing horizontal and vertical geodetic networks. However, these conventional positioning techniques have many drawbacks such as time-consuming, too costly, and require massive effort. Thus, the Global Navigation Satellite System (GNSS) has been invented to fulfill the quickness, increase the accuracy, and overcome all the difficulties inherent in almost every surveying fieldwork. This research assesses the accuracy of local geodetic networks using different Global Navigation Satellite System (GNSS) techniques, such as Static, Precise Point Positioning, Post Processing Kinematic, Session method, and finally Real Time Kinematic for different surveying applications. To achieve this assessment, GNSS observations were executed to highlight the characteristics for each GNSS observation technique. Furthermore, the level of accuracy which is gained from each positioning technique is enormously investigated to figure out the amount of allowable error and the suitability for different geodetic applications. In relative positioning, at least two receivers (or more) are required for timing and positioning while the Precise Point Positioning necessitates single receiver. Some of geodetic applications require about positions with centimeter level of accuracy or less. The robust geodetic networks provide accurate positions which in turn serve different earth science applications.

"Se não aguentar, corra!": um estudo sobre a pedagogia do sofrimento em um curso policial militar
Authors: Gomes França Fábio , Gomes Janaína Letícia de Farias
Published: April 2023

Neste artigo analisam-se as nuances que nortearam o Estágio de Operações Táticas com Apoio de Motocicletas (Eotam), realizado por uma Polícia Militar no país em 2014. Para tanto, realizaram-se entrevistas abertas com alguns participantes do referido curso de aperfeiçoamento policial militar. Por esse foco, importou utilizar metodologicamente os relatos pretéritos, por meio da história oral, o que permitiu apreender relatos das experiências tanto de oficiais quanto de praças sobre as situações de humilhação e sofrimento físico vivenciadas, as quais ainda reproduzem a crença policial militar de que o sofrimento faz parte da conquista de um brevê militar. Ratifica-se a urgência dessa discussão no campo da segurança pública, visto que a lógica desse tipo de pedagogia carrega de forma implícita um ideal belicista que corrobora a existência da violência policial militar devido ao fato de os policiais enaltecerem valores como a masculinidade, a força e o machismo.

Authors: Tomesani Marques Ana Maura
Published: April 2023

O artigo busca reconstituir a trajetória do Conselho Nacional de Segurança Pública desde o momento em que a ideia de reativação do antigo CONASP, criado em 1989, surge no gabinete da Secretaria Nacional de Segurança Pública em 2007 até a penúltima reunião ordinária realizada pela atual composição do conselho em agosto de 2014, passando pela 1ª CONSEG (2009) e pelos Diálogos Regionais (2014). Destacam-se tensionamentos e avanços verificados no âmbito do Conselho e algumas sugestões são esboçadas no intuito de melhorar a imagem, a divulgação e a efetividade das ações do colegiado – questões que parecem centrais para seus membros e que vêm ocupando grande espaço na pauta de suas discussões desde 2010.

Este trabalho busca refletir sobre a estrutura do poder municipal e as políticas de segurança num novo paradigma federativo. Para tanto, estuda-se a posição ocupada pelo município na Federação brasileira, o que remete à compreensão da sua autonomia no campo das políticas públicas. Na sequência, perscrutam-se as políticas de segurança e as respectivas competências municipais, na perspectiva de um novo paradigma da segurança pública. Por fim, analisam-se as administrações dos municípios com mais de 50 mil habitantes, em três faixas populacionais, para aferir se houve acréscimo no número de secretarias municipais de segurança e de guardas municipais armadas. Conclui-se pela competência do município de agir na segurança pública, o que também é demonstrado pelo maior número de órgãos locais a agir nestas políticas públicas.
Novas polícias? Guardas municipais, isomorfismo institucional e participação no campo da segurança pública
Authors: De Oliveira Junior Almir , Alencar Joana Luiza Oliveira
Published: April 2023

Os municípios vêm ocupando cada vez mais espaço no campo da segurança pública no Brasil e, como parte desse movimento, as guardas municipais podem ser consideradas uma inovação institucional no setor. A participação e o empoderamento popular na segurança podem se dar em conselhos comunitários, que se pretendem espaços de escuta das comunidades. Nesse sentido, as guardas municipais são atores relevantes, com capacidade de apoio e implementação de ações preventivas que deem resposta às demandas que emergem nesses espaços de participação. Contudo, a tendência, muitas vezes presente, de se tornarem organizações semelhantes às polícias militares faz com que as guardas municipais corram o risco de reproduzir uma postura de certo distanciamento em relação à população, voltada para ações ostensivas de enfrentamento à criminalidade, em vez de privilegiar um modelo com foco na atuação preventiva, como preconizado no Estatuto das Guardas.
