Hekimlerin Sağlık İletişim Düzeyleri ve Kullandıkları Modellerin İncelenmesi: Odak Grup Çalışması
Authors: Acar Nihal
Published: March 2024

Sağlık hizmetlerinin sunumunda meydana gelen değişiklikler 1970 yılında küresel olarak yeni sağlık politikaları ortaya çıkartmıştır. Bunlardan biri olan sağlık iletişimi, ülkelerin gelişmişlik düzeyleri ile yakından ilişkili toplumsal ve bireysel sağlığın korunmasına yardımcı yeni bir uygulamadır. Sağlık iletişimi kavramı, ilk dönem, iletişim araştırmalarında sıklıkla hastalar açısından incelenmiştir. Fakat kavram temelde tüm sağlık çalışanları ile hasta ve hasta yakınlarını kapsamaktadır. Bu araştırma, alanda bulunan eksikliği kapatmak için hekimlerin iletişim düzeyleri ile iletişim modellerini belirlemek üzere nitel araştırma yöntemlerinden odak grup çalışması ile inşa edilmiştir. 10 hekim ile yürütülen araştırma sonunda doktorların “hekim-hasta” kategorisinde iletişim kurduğu saptanmıştır. Araştırmanın bir başka bulgusunda, hekimlerin sağlık iletişimi modellerinden retorik model dışında kalan 6 farklı modeli de hastanın sosyo-ekonomik ve psikolojik özelliklerine göre kullandıkları anlaşılmıştır. Araştırma sonunda hekimlerin, hastaları ile daha kaliteli bir sağlık iletişimi kurmaları için muayene sürelerinin uzatılması, günlük bakılan hasta sayısının azaltılması ve sağlık iletişimi politikalarının geliştirilmesi önerilmiştir.

Published: March 2024

2000'li yılların başında yaşanan mali krizler, düşük ve orta gelirli ülkelerin dış borç yükümlülüklerine ilişkin yaklaşımlarının evrimleşmesine neden olmuştur. Bu nedenle, dış finansmanın sadece ekonomik faydalarına odaklanmanın sürdürülebilirlik açısından yetersiz olduğu anlaşılmıştır. Geliştirilecek yeni dış finansman yaklaşımları ile çevresel ve toplumsal meselelere ilişkin özgün perspektiflerin sisteme entegre edilmesi beklenmektedir. Bu bağlamda gündeme gelen Borç-Doğa Takası mekanizması ekonomik büyüme ile sürdürülebilir kalkınmayı bir araya getirmeyi amaçlayan bir yaklaşım olması nedeniyle dikkat çekmektedir. Bu çalışmanın ana amacı Borç-Doğa Takası mekanizmasının işleyişini derinlemesine irdelemektir. İlgili kapsamda mekanizmanın avantaj ve sınırlılıkları tartışılacak; ek olarak vadettiği çevresel katkının ölçeği değerlendirilecektir.

Birey, siyasal ve toplumsal anlamda sosyalleşmeye ilk olarak ailede adım atmaktadır. İleriki yaşamında ise formel ve informel çevresiyle bulunduğu ilişki sonucunda siyasal ve toplumsal sosyalleşmesi şekillenmektedir. Bireyin bu alanlarda kimliğinin şekillenmesinin bir diğer önemli unsuru ise jenerasyon, kuşak ya da bir diğer ismiyle nesil kavramıdır. Kuşaklar genel olarak belirli zaman diliminde dünyaya gelen, süreç içerisinde benzer deneyimleri yaşayan ve bunun sonucunda benzer özellikler, tutumlar ya da inançlar taşıyabilen bireyleri ifade etmektedir. Bu çalışma, Y ve Z kuşağı bireylerinin siyasal tutum ve davranışını etkileyen faktörlere, ilgili bireylerin siyasal ilgilenim ve siyasal katılım düzeylerine yoğunlaşmaktadır. Bu doğrultuda çalışma kapsamında öncelikle ilgili bireylerin siyasal tutum ve davranışlarını etkileyen unsurlar literatürde oy verme modelleri olarak bilinen “Psikolojik, Sosyolojik ve Rasyonel” oy verme yaklaşımları çerçevesinde ne gibi farklılıkların veya benzerliklerin olduğunun ortaya koyulması amaçlanmakta, ayrıca ilgili bireyler, siyasal olaylara veya konulara ilişkin ilgi düzeyleri ve siyasal alana katılım düzeyleri açısından karşılaştırmalı bir olarak incelenmesi amaçlanmaktadır. Bu doğrultuda 1980-2004 yaş doğumlu toplam 617 katılımcı ile saha araştırması yürütülmüştür. 04 Mart – 31 Mart 2022 tarihleri arasında anket tekniği kullanılarak gerçekleştirilen araştırmada Y ve Z kuşağı bireyleri arasında siyasal konulara ilgi ve katılım düzeyleri açısından farklılıklar ortaya çıkarken; oy verme yaklaşımları açısından ise çeşitli noktalarda benzeşmelerin ve farklılaşmanın meydana geldiği görülmüştür.

Authors: Hindriana Anna Fitri , Handayani Handayani , Setiawati Ina
Published: March 2024

Connecting related concepts can enable learners to obtain holistic knowledge but designing integrated learning must consider high element interactivity between concepts, so that learning would not result in excessive cognitive load, which will instead hinder learning. The promising benefit of learning plant anatomy and physiology in connected integrated learning was analyzed by assessing preservice biology teachers’ identification and information analysis skills. The influence of learning approach on their cognitive load was also analyzed. Results suggested the advantage of learning in an integrated way, in which cognitive load can be managed by considering the correlation between cognitive load elements.
HOW DO STUDENTS THINKING PROCESS IN SOLVING THE VISUALLY REPRESENTED QUESTIONS?
Authors: Remme' Beatric Videlia , Delastri Lusiana
Published: March 2024

Problems that are represented visually can develop students' relational and logical understanding. Relational and logical understanding in geometry learning can reinforce certain relationships and develop cognitive functions, such as knowledge construction. In the process of constructing knowledge and constructing problem solving requires students' thinking processes. This study aims to describe students' thinking processes in solving problems that are represented visually. The thought process is based on reflective abstraction. The type of research that is appropriate to achieve these objectives is qualitative. The research subjects are 4 students who have studied the material of flat shapes. The results showed that the concepts represented visually could inspire various ideas in solving problems. In solving problems, the thinking process based on reflective abstraction depends on the history of the solver's knowledge. The mental mechanisms that occur when solving problems with visual representations are interiorization, coordination and encapsulation. Concepts presented using visual representations can increase in-depth understanding, but can also be a source of misconceptions for students. Error answers obtained are the result of misconceptions about concepts/information that have been interiorized into concepts presented using visual representations.

Analytical techniques for elemental analysis in the soil-plant system have significance importance, especially emerging techniques such as synchrotron radiation (SR). Improved techniques allow samples to be examined in a non-invasive manner at high speed and resolution, resulting in better sample data. By applying various analytical techniques based on SR, it is possible to gather different information about the structure of the studied samples. In mining ecology, such techniques are widely used in assessing heavy metal-polluted sites, i.e., overburden dumps and areas around operating and mothballed mines. The present review elaborated insights into different analytical techniques for applying SR in plant-soil samples. The review also compared traditional research techniques with SR-based emerging and improved techniques. The need to use SR techniques for the complex diagnostics of sample structures to study their elemental and phase composition is substantiated. Using an integrated approach with SR, we can study the dynamics and speciation of HMs with carrier phases and uncover the mechanisms underlying the interactions between the adsorption centers of minerals, organic components, and heavy metals. It also improves the efficiency and accuracy of analysis and broadens the range of information obtained, which could lead to a more precise analysis of samples.

Published: March 2024

The study was conducted in the Hyang-Argopuro volcanic mountain in Jember, Indonesia, with the aim of assessing the distribution of soil minerals along a toposequence and their relationship to soil genesis. Three soil profiles representing the upper, middle, and lower slopes of the toposequence were analyzed. The results revealed that the predominant sand minerals in the soils are opaque minerals, weatherable minerals, amphibole groups, and ferromagnesian minerals. The presence of magnetite, primarily found in the soil profile on the upper slope, suggests the effect of the well-drained topography on its formation. Clay mineral analysis showed that halloysite dominates in soil profile 1, along with traces of gibbsite and cristobalite in the surface horizon. Soil profile 2 is characterized by a combination of halloysite and illite, while kaolinite and illite dominate in soil profile 3. The presence of illite in these soils aligns with previous studies conducted in volcanic regions. The degree of soil development follows the sequence: Soil Profile 2 > Soil Profile 1 > Soil Profile 3. This corresponds to the soil classification, where soil profile 3 is classified as an Alfisol, soil profile 1 as a Mollisol, and soil profile 3 as an Inceptisol. The Andic properties, such as low bulk density and high pH in NaF, observed in soil profile 1 suggest its development from an Andisol. Overall, the study findings highlight the significant influence of basaltic andesite parent material, mountainous topography, and warm and wet climate on the mineral composition and development in the area.
Parametrical synthesis of various radio devices with the set quantity of cascades of type «the mixed two-port network – nonlinear part»
Authors: Golovkov Alexander A.
Published: March 2024

Background. Presence of possibility of analytical definition of a part of parametres of various radio devices, optimum by criterion of maintenance of preset values of modules and phases of transfer functions on necessary quantity of frequencies, considerably reduces time of numerical optimisation of other part of parametres by criterion of formation demanded PFC and FFC in a strip of frequencies. Till now such problems dared concerning radio devices only with one cascade of type «a nonlinear part - the coordination the device» or «the coordination the device - a nonlinear part». In quality coordination devices were used the jet, resistive, complex or mixed two-port networks. The problem of multicascade radio devices with jet two-port networks is solved also. Change of basis for the coordination two-port networks and a place of inclusion of a nonlinear part leads to change of area of a physical realizability.
Aim. Working out of algorithms of parametrical synthesis of radio devices with any quantity of identical and unequal cascades of type «the coordination the mixed two-port network – a nonlinear part» by criterion of maintenance of the set frequency characteristics. Nonlinear parts are presented in the form of a nonlinear element and parallel either consecutive on a current or pressure of a feedback.
Methods. The theory of two-port networks, matrix algebra, a decomposition method, a method of synthesis of actuation microwave devices, numerical methods of optimisation.
Results. In interests of achievement of the specified purpose systems of the algebraic equations are generated and solved. Models of optimum two-port networks in the form of mathematical expressions for definition of interrelations between elements of their classical matrix of transfer and for search of dependences of mixed of two-poles from frequency are received. It is shown, that at certain parities between quantity of identical cascades and values of resistance of a source of a signal and loading of the one-cascade radio device frequency characteristics of one-cascade and multicascade radio devices appear identical or similar. Such schemes are named by equivalent. Use of unequal cascades leads to substantial growth of a working strip of frequencies.
Conclusion. The comparative analysis of theoretical results (PFC and FFC radio devices, value of parametres), received by mathematical modelling in system «MathCad», and the experimental results received by scheme modelling in systems «OrCad» and «MicroCap», shows their satisfactory coincidence.
Antenna array of waveguide elements with dielectric phasing sections
Authors: Pasternak Yuri G. , Pendyurin Vladimir A. , Proskurin Dmitry K. , Safonov Kirill S.
Published: March 2024

Background. The need to develop and continuously improve mobile and on–board high-speed satellite communication terminals, as well as satellite communication equipment with high secrecy of operation, emitting ultra-wideband signals, the spectral power density of which, measured at the input of receiving devices of radio monitoring complexes, should be significantly lower than the spectral power density of noise, is due to the following circumstances: ensuring reliable and high-quality communication military and civilian users; the development of the domestic element and technological base, import substitution; the need for rescue services in small-sized information transmission and reception systems; the need to develop satellite control systems for military and civilian equipment; the development of precision agriculture programs. An antenna array made of waveguide elements with dielectric phasing sections can serve as one such example.
Aim. The model of the antenna element is considered, and its main characteristics are also given. A model of a linear antenna array consisting of 32 waveguide elements with phasing sections has been developed. Linear and flat antenna arrays based on a common-mode and equal-amplitude 1:32 power divider and antenna elements are considered. A model of a flat antenna array composed of 16 linear antenna arrays is also constructed and its main characteristics are given.
Methods. The antenna element model is based on a circular waveguide with an internal diameter of 18 mm and a dielectric plate, the plane of which is oriented at an angle of 45° to the lines of force of the electric field intensity vector. The linear antenna array is powered by an equal amplitude and common-mode power divider, and the linear and flat antenna arrays are based on square waveguides with internal dimensions of 14×14 mm2 with beveled internal corners.
Results. It is shown that the gain at a frequency of 10,95 GHz is 32,5 dB (normal) and 31,2 dB when the beam is deflected by ±37,5° in the angular plane. The gain at a frequency of 11,7 GHz is 33,8 dB (normal) and 32,5 dB when the beam is deflected by ±37,5° in the angular plane. With the maximum deviation of the main lobe from the normal, the level of the side lobes in the vertical increases to the level of -11,4 dB, which slightly exceeds the UBL with in-phase and equal amplitude field distribution in the headlight aperture (-13,2 dB).
Conclusion. In the considered headlight design, the positioning of the main lobe of the radiation pattern in the azimuthal plane is carried out by mechanical rotation of the antenna system. The rejection of two–coordinate electronic scanning was chosen based on considerations of reducing phase shifters (or high-frequency switches) and reducing the cost of headlights.
Reciprocal action of natural bianisotropy and artificial chirality on electromagnetic propagation in medium
Authors: Zeyde Kirill M.
Published: March 2024

Background. The present article investigates the reciprocal action of specific medium effects on electromagnetic waves propagation. The object of study is a moving dielectric, which at rest already demonstrate bianisotropic properties, i. e., it is a synthetic material, e. g., chiral media with Ω-particles. Bianisotropic material equations are the most general for describing the effects of electromagnetic waves interaction with complex medium. Studying and analyzing them is proving to be a notable scientific problem. Natural bianisotropy is a property of simple media under special conditions (state of motion, internal currents and diffusion processes), whereas artificial bianisotropy is an inherent property of the synthetic material itself (composite material, material with different metaparticles).
Aim. The main goal of the work is to generalize the already available data. On it basis, then, obtain analytical expressions, which can be effectively used for the experiments designing, creating new computational techniques for solving direct and inverse electromagnetic diffraction problems.
Methods. In this paper, analytical methods are applied to obtain the resulting close-form expressions.
Results. Three classes of effects have been identified that have a significant reciprocal effect on each other: gyrotropy, spatial dispersion, and temporal dispersion. In this article it was shown that the gyrotropy of the medium has not only a simple additive effect, but under some, specific conditions, can be related to the system emergence.
Conclusion. The reciprocal action of the spatial dispersion of the moving chiral medium, generally has different scales in range. Temporal dispersion was investigated, which does not have a simple additive property, because even an isotropic medium acquires fundamentally new material properties of bianisotropy when it moves.

Published: March 2024

OBJECTIVES:The World Health Organization (WHO) has reported carbapenem-resistantEnterobacteriaceae(CRE), carbapenem-resistantAcinetobacter baumannii(CRAb), and carbapenem-resistantPseudomonas aeruginosa(CRPa) as critical priority pathogens for human health. Therefore, this study aimed to review clinical carbapenem resistance systematically and comprehensively in West Africa.

DATA SOURCES:A total of 102 research articles on carbapenem resistance from the sixteen countries forming the West African region were included in this review.

DATA SYNTHESIS:Carbapenem-resistant bacteria (CRB) were isolated mainly from urine 73/300 (24.3%) and pus/wounds of patients 69/300 (23%). The mean prevalence of CRB in West Africa was 4.6% (1902/41635), ranging from 1.6% to 18.6%. CRB identified were mainlyEscherichiaspp. (34/130; 26.1%),Klebsiellaspp. (27/130, 20.8%),Pseudomonasspp. (26/130, 20%), andAcinetobacterspp. (25/130; 19.2%). Bacteria isolated in West African countries produced carbapenemases that belong to the four Ambler classes and include 13 types. TheblaOXA-type (34/104; 32.7%),blaNDM(31/104; 29.8%), andblaVIM(13/104; 12.5%) were the most common carbapenemase genes. These genes are carried by plasmids, composite transposons, and integrons. The Kirby-Bauer disc diffusion method (74/172; 43.0%), PCR (38/172; 22.1%), and whole genome sequencing (17/172; 9.9%) were the most common methods for carbapenem resistance detection. The most reported alternative antibiotics active against CRB were amikacin, colistin, and fosfomycin.

CONCLUSION:There is an urgent need to take synergistic action to delay, as much as possible, the occurrence of CRB epidemics in West Africa.

With the development of modern educational technology, micro courses, a new type of educational resource, have been continuously developed in school teaching in China. However, the problems encountered by teachers in creating micro lessons have hindered their application and practice. At the same time, students have put forward higher requirements for the presentation form of micro lessons during the learning process. Therefore, it is particularly important to find a more suitable micro lesson production tool for teachers to use and present results that can meet students’ needs (Yulong [1]). Freeze frame animation, as an art form emerging from film art, is easy to produce with low entry requirements, and can reduce the difficulty of micro course design by presenting static images in dynamic effects. Combining the characteristics of various subject knowledge points, use freeze frame animation to create micro lessons to help teachers create micro lessons.

Background: Groundnut is a globally significant oil crop. It possesses diversity in the nutritional and medicinal values. Groundnut kernels contain 48%-50% oil, 26%-28% protein and vitamins B and E. Continuous efforts to enhance groundnut productivity is the main driving force for the current study. Methods: Line × Tester analysis was carried out to estimate the gene action of yield and its attributing traits for their improvement. Seven lines viz., VRI 7, VRI 8, VRI 9, VRI 10, K 6, GG 7 and CO 7 and eight testers viz., IGCV 15402, IGCV 15412, IGCV 15432, IGCV 15427, IGCV 15426, IGCV 15408, IGCV 15410 and IGCV 15388 were crossed to obtain 56 crosses. GCA and SCA variance revealed the importance of both additive and non-additive gene action of all the traits. Result: The study observed significantly higher specific combining ability (SCA) variances compared to general combining ability (GCA) variances, indicating a predominant role of non-additive gene action in trait control. Line VRI 7 was observed best GCA, particularly for pod yield and other traits making it a promising variety for pod yield enhancement programs in the future. The SCA for hybrid VRI 8 × ICGV15426 and VRI 7 × ICGV15402 revealed superior performance in terms of pod yield per plant. Notably, the VRI 7 × ICGV15402 cross exhibited outstanding performance across all traits, highlighting the prominence of a parent with strong GCA. The study recommends early-generation selection as a strategic approach for improving groundnut breeding efforts.

Background: Sheep is one of the important species of livestock in India contributing to meat production. India has 44 distinct breeds of sheep, out of which 10 are found in Tamil Nadu. The present study describes the molecular characterization of recently registered breed of sheep - Katchaikatty sheep, genetic variability and genetic structure of the population by microsatellite marker analyses. Methods: DNA from 50 unrelated Katchaikatty sheep was amplified with 25 FAO recommended fluorescent tagged ovine-specific microsatellite markers and genotyped on an automated Genetic Analyzer. In each locus, observed (no) and effective number of microsatellite alleles (ne), allele frequencies, observed (Ho) and expected (He) heterozygosity and heterozygosity deficit estimate (FIS), polymorphism information content (PIC) and Chi-square (χ2) test for Hardy-Weinberg equilibrium (HWE) were assessed. Mode-shift analyses were performed. Result: The study revealed a total of 144 alleles across all the loci. The number of alleles at each locus varied from one to 10 with a mean of 5.76 alleles. The PIC values in the microsatellite loci ranged from 0.34 (OarAE129) to 0.83 (OarFCB48) with an average of 0.59, which showed a high genetic polymorphism. Six out of 25 microsatellite loci studied were in Hardy-Weinberg equilibrium and 19/25 loci showed positive FIS values. The overall mean observed and expected heterozygosity were 0.50 and 0.65 respectively and the estimates elucidated a substantial genetic variability in Katchaikatty sheep population. Mode shift analysis revealed a normal L-shaped curve, describing that the Katchaikatty population had not experienced any genetic bottleneck and remained in mutation-drift equilibrium.
Current issues of intercultural interaction: experience of western countries
Authors: Pistoletov Danil
Published: March 2024

The current difficulties of intercultural interaction, experience of counteracting xenophobia and other problems are considered in the framework of the article on the example of Western countries, mainly the United States, as a state with a significant proportion of its population, including in percentage ratio, occupied by representatives of different races and cultures. In the course of the research the relevance and acuteness of the problems of intercultural interaction are assessed, the problems of weakening of peoples' self-awareness and formation of complexes of the race accused of xenophobia, as well as attempts to introduce xenophobic ideas into science are considered. The author also touches upon the topic of selective tolerance. The research is based on the analysis of scientific and informational publications on the topic under study, both domestic and foreign, representing an inside view of the problem. The material considered in the article allows us to conclude that the problems of intercultural relations in the United States are becoming more and more complicated over time, and similar processes are taking place in other Western countries, which gives grounds to recognize the policy of fighting xenophobia as ineffective. These articles can be used as a basis for further research into the problems of intercultural interaction and the possible development of measures for the settlement and subsequent prevention of these problems.

Authors: Guseletov Boris
Published: March 2024

The article examines the consequences of the change of the Polish government, headed by the right-wing Euro-skeptical Law and Justice party, which has led this country since October 2015. The article presents an analysis of the results of the parliamentary elections in Poland, held on October 15, 2023, in which the PiS won a formal victory, which, however failed to form a majority coalition. As a result, the ruling alliance, which received the right to form a government, was made up of the pre-election association of the parties Civic Coalition, which included the Civic Platform parties led by former Prime Minister Donald Tusk, Modern, the Greens and the Polish Initiative, the Third Way association, which included the parties Poland 2050, the Polish People's Party, the Center for Poland, and the Union the European Democrats, as well as the union of the Left, consisting of the parties New Left and Left together. The assessment of the activities of the leading Polish political parties over the previous four years is given, the main provisions of the election platforms of the main parties and coalitions that were elected to parliament following these elections are analyzed. To identify the dynamics of changes in the political situation in Poland, a comparative analysis of the results of the leading political parties of this country in the elections of 2019 and 2023 was carried out, as well as their main characteristics. The key differences in the approaches of the country's leading parties to the IpR and the Civic Platform on domestic and foreign policy issues, including their attitude to Russia's special military operation in Ukraine, are analyzed. The process of forming a new Polish government and the influence of the country's President Andrzej Duda on it is considered.
Gastrointestinal involvement in Fabry disease
Authors: Politei Juan Manuel , Solar Benjamin
Published: March 2024

Fabry disease is an X-linked lysosomal storage disorder due to alpha-galactosidase A deficiency. This deficiency results in a progressive accumulation of globotriaosylceramide and related glycosphingolipids, particularly in vascular endothelial cells, renal cells, nerve cells, and cardiomyocytes. Gastrointestinal symptoms are frequent and can be extremely debilitating. It is known that most of the well-characterized gastrointestinal manifestations of Fabry disease are the result of the accumulation of glycosphingolipids, which causes vascular occlusion and malfunction of the peripheral and autonomic nervous system. Although improvement is noted in treating patients with enzyme replacement therapy and migalastat, some continue to experience symptoms after treatment; thus, it remains a significant cause of morbidity, necessitating concurrent adjuvant treatment. Current research is focused on clarifying the underlying dysmotility and further analyzing the correlation between the gut-brain axis, the histologic disease progression, and the clinical symptom presentation.
Space Theory
Authors: Chen S.
Published: March 2024

The author introduces a novel theoretical framework that suggests matter and energy are both converted from curved space. In Space Theory, gravitation is generated by the flow of space, instead of being transmitted by the graviton as in String Theory. This theory also suggests that Newton's gravitational constant, denoted as G, may not be truly constant but could vary over time. The equivalent equation of space is S=Ec2=mc4, and the gravitation of hollow sphere space is Sμν=4πGm=(4/3)π((r+a)3-r3). The Space Theory also predicts that the surface gravitational acceleration of the neutron star Crab Pulsar (PSR B0531+21) is approximately 8.21924883×106 m/s2.
