Published: July 2022

Este estudo teve como objetivo comparar a avaliação da resistência aeróbia avaliada pelos testes de McArdle e Conconi e associar as medidas indiretas com a percepção subjetiva por meio da Escala de Capacidade Percebida (ECP). Foram recrutados 29 participantes, 17 homens e 12 mulheres, com idades iguais ou maiores de 18 anos da região de São José, Santa Catarina. Após os recrutamentos foram analisados variáveis como sexo, idade, estatura, massa corporal, frequência cardíaca e esforço físico por meio dos testes de banco de McArdle e Conconi, além da capacidade percebida por meio da ECP. A média da pontuação da ECP foi de 9,72 (DP = 1,60). O Índice de Correlação Intraclasse entre os dois testes foi considerando excelente (r = 0,939; p < 0,001). Além disso, ambas análises apresentaram associação com a variável desfecho. No entanto, o poder explicativo da Regressão Linear, considerando como variável independente o VO2max a partir do deste de McArdle foi maior (45,3%). Assim, recomenta-se a utilização da tabela de referência deste teste para identificação do VO2máx a partir da percepção subjetiva pela ECP. Desta forma, a ECP pode ser uma ferramenta valiosa na avaliação, prescrição de exercícios e em estudos epidemiológicos por sua fácil e rápida aplicabilidade em adultos ativos fisicamente.

Published: July 2022

Characteristic mode analysis (CMA) is used in the design and analysis of a wide range of electromagnetic devices such as antennas and nanostructures. The implementation of CMA involves the evaluation of a large method of moments (MoM) complex impedance matrix at every frequency. In this work, we use different open-source software for the GPU acceleration of the CMA. This open-source software comprises a wide range of computer science numerical and machine learning libraries not typically used for electromagnetic applications. Specifically, this paper shows how these different Python-based libraries can optimize the computational time of the matrix operations that compose the CMA algorithm. Based on our computational experiments and optimizations, we propose an approach using a GPU platform that is able to achieve up to 16×× and 26×× speedup for the CMA processing of a single 15k ×× 15k MoM matrix of a perfect electric conductor scatterer and a single 30k ×× 30k MoM matrix of a dielectric scatterer, respectively. In addition to improving the processing speed of CMA, our approach provided the same accuracy as independent CMA simulations. The speedup, efficiency, and accuracy of our CMA implementation will enable the analysis of electromagnetic systems much larger than what was previously possible at a fraction of the computational time.

Published: July 2022

In this paper, a low-cost, simple, and reliable bi-static radar cross-section (RCS) measurement method by using a historic Marconi set-up is presented. It uses a transmitting (Tx) antenna (located at a constant position, at a reference angle of θ=0∘θ=0∘) and a moving receiver (Rx) antenna. A time gating method is used to extract the information from the reflection in the time domain; applying time filter allows removing the antenna side-lobe effects and other ambient noises. In this method, the Rx antenna (on the movable arm) is used to measure the reflected field in the angular range from 1∘1∘ to 90∘90∘ from the structure (printed circuit board, PCB) and the reference configuration represented by a ground (GND) plane of the same dimension. The time gating method is then applied to each pair of PCB/GND measurements to extract the bi-static RCS pattern of the structure at a given frequency. Here, a comparison of measurement results is carried out at 18 and 32 GHz with simulation ones indicating successful performance of the proposed method. It can be used as a low-cost, reliable, and available option in future measurement and scientificresearch.

Published: July 2022

In this paper, a novel planar Butler matrix (BM) utilizing only 3dB3⁢dBhybrid couplers and a crossover are implemented using a low-cost silver-nano inkjet printing technique. Unlike in the conventional design of BM where a phase shifter is required, this novel design does not need a phase shifter to be implemented. However, the use of delicate substrates like polyethylene terephthalate (PET) in the design makes it unique. This is not possible with the conventional thermal curing process, as PET substrate cannot be subjected to an excessively feverish temperature. The results obtained show good return loss and transmission coefficients better than 26.1026.10 and 23.54dB23.54⁢dB, respectively, at the center frequency. Similarly, an amplitude imbalance of less than 2.4dB2.4⁢dB with phase mismatch within ±0.25∘±0.25∘ is achieved at the center frequency. The BM has a −10dB-10⁢dB bandwidth of 24.79% with a beam pattern produced at +13∘+13∘,−40∘-40∘, +40∘+40∘, and −13∘-13∘ when ports 1-4 of the BM are energized.

Authors: Huang Qianling , Xu Xiaofei , Zhang Ruiheng 
Published: July 2022

This work is focused on how to efficiently shrink a patch antenna operating in the UHF band. Five typical independent methods are first introduced that were solely used to realize a small patch antenna. A potential combination method is further discussed utilizing two or more of these five methods. One miniature patch antenna is experimentally demonstrated operating at 735 MHz using the combination method, in which both of shorting wall and complementary split ring resonators are applied in a reconciling way. A two-step optimization procedure is given to show how the antenna sizes can be significantly reduced with this combination method. The antenna is fabricated on a simple dielectric with a low εεrr of 2.2. The patch size is only 0.127λλ ×× 0.123λλ. The antenna efficiency is considerably high as 77% in measurement.
FOREIGN EXPERIENCE IN ENSURING GENDER EQUALITY: SOCIAL AND LEGAL RESEARCH
Authors: Golovinova Yuliya V. 
Published: July 2022

The article is devoted to identifying the foreign positive experience of the Nordic countries in the construction of a social policy of gender equality. Based on the involvement of a wide regulatory framework in textual content analysis, which consolidates the mechanisms for ensuring the principle of gender equality, the author emphasizes the versatility and consistency in the development of strategies and policies and social practices for equal rights for men and women. The author emphasizes that, in particular, in Finland, the minimization and leveling of gender asymmetry is supported by the national quota system. This approach is aimed at comprehensively ensuring a gender-neutral configuration of social practices. Such a humanistic trajectory of the policy of gender equality finds consolidation at the level of special legislation. The publication found that guided by both imperative and dispositive principles in this group of countries, a whole system of anti-discrimination legislation was adopted and is being effectively implemented. Through the establishment of special public authorities in Norway, Finland, Iceland and Sweden, state guarantees of the principle of gender equality are fully ensured.
N.M. YADRINTSEV AND G.N. POTANIN: REGIONAL EXPERIENCE OF SOCIAL CONSIDERATION OF THE INTEGRATION POTENTIAL OF ETHNOCULTURAL INTERACTION
Authors: Golovinov Alexandre V. , Golovinovа Yulia V. 
Published: July 2022

The article is devoted to the reconstruction of the socio-philosophical views of the ideologists of the movement of Siberian regionalists on the interaction of ethnic cultures. The relevance of addressing the ideological heritage of the patriots of Siberia is due to several circumstances. Firstly, 2022 marks exactly 180 years since the birth of Nikolai Mikhailovich Yadrintsev, the leader of Siberian regionalism. Secondly, the current state of interethnic relations, unfortunately, is accompanied by contradictions and some conflict clashes against the background of ethnic stereotypes rooted in the minds of the masses. Therefore, the appeal to the creative heritage of G.N. Potanin and N.M. Yadrintsev, in which attempts were repeatedly made to theoretically comprehend the harmonization of interethnic interactions, seems to be relevant.
Based on the analysis of the journalism of regional thinkers, the authors found that the progressive movement of ethnoculture acquires the direction of social integration, cultural progress is regarded not as a transition from the lower to the higher, but as a natural modification of the ethnocultural features of the subethnos. The publication shows that the alternative approach of N.M. Yadrintsev and G.N. Potanin to ethno-cultural interaction allows us to present the policy in the field of culture through the interaction and struggle of two lines - "hard", aimed at standardization and unification of cultural activities, and "soft", allowing the coexistence of cultures of different types. All this is possible, according to the teachings of the regionalists, with equal access to any kind of resources.

BACKGROUND
First trimester vaginal bleeding is an obstetric high-risk, early registration of pregnancy regular antenatal visits and good awareness to the pregnant women and their family members about first trimester vaginal bleeding and the sequelae and the early and remote obstetric and neonatal outcome are needed. The purpose of the study was to observe the effect of first trimester bleeding on maternal & foetal outcomes.
METHODS
This study involved all women attending the antenatal clinic at the Department of Obstetrics and Gynaecology with a history of vaginal bleeding in the first trimester or the second trimester or third trimester with prior history of first trimester bleeding at Basaveshwar and Sangameshwar Hospital, attached to MRMC, Kalaburagi. It included a total of 100 singleton pregnant women with vaginal bleeding in the first trimester of pregnancy that was confirmed ultrasonographically. Patients were closely observed and follow-up done 2 weekly up to 36 weeks and weekly after that till delivery. The maternal and foetal outcomes were studied.
RESULTS
In the present study, first trimester vaginal bleeding was seen maximum in the age group of 21-25 years about 47 %, seen more in Multigravida 52% than primigravida 44% and 4% in Grandmultipara. Maternal adverse outcomes such as abruption in 8 % of cases, placenta pravia in 15% of cases, placenta accreta in 2 % of cases, preeclampsia in 12 % of cases and PROM in 18 % of cases and preterm labour in 21 % of cases were observed. Among 63 live births, 38 were term babies, 19 were early preterm, 2 were late preterm babies, and 8 were IUGR babies.
CONCLUSIONS
In the first trimester, vaginal bleeding is one of the predictors of poor maternal and foetal outcomes later in pregnancy. Both maternal and foetal outcomes are studied considering pregnant women with first-trimester vaginal bleeding as a high-risk category. Proper evaluation of a pregnant woman with first-trimester vaginal bleeding, regular antenatal care, methodical evaluation of bleeding and regular follow-up with the lookout for maternal and foetal complications and awareness to the woman and family members and knowledge about warnings signs in pregnancy to be explained. Proper clinical examination and ultrasonographic evaluation & timely obstetric consultation and interventions play an important role in the management of patients with first-trimester vaginal bleeding.

Effect of engraved concentric circles on pool boiling of water
Authors: Singh Saurabh , Kumar Manoj , Patil Anil Kumar 
Published: July 2022

Abstract
Pool boiling takes place when a stagnant liquid is placed on a surface above the saturation temperature of the liquid. Thermal studies have attracted a large number of researchers working in different segments of the industry to meet the heating and cooling demands of each individual. The pool boiling is a highly effective technique of convective heat transfer to maintain the system operation under safe temperature and safe temperature limits for better performance and longevity. This study investigates the effect of engraved concentric circles on aluminium disc in de-ionized water. The experiments are conducted by varying pitch ratio (P) and indentation ratio (I) of engraved concentric circles in the range of 0.0125–0.05, and 0.002–0.008, respectively. The maximum enhancement in the boiling heat transfer coefficient is found to be 21.11% more than that of a plain surface corresponding to the pitch ratio of 0.0125 and indentation ratio of 0.008.
Molecule graph reconstruction from atomic force microscope images with machine learning
Authors: Oinonen Niko , Kurki Lauri , Ilin Alexander , Foster Adam S. 
Published: July 2022

Abstract
Despite the success of noncontact atomic force microscopy (AFM) in providing atomic-scale insight into the structure and properties of matter on surfaces, the wider applicability of the technique faces challenges in the difficulty of interpreting the measurement data. We tackle this problem by proposing a machine learning model for extracting molecule graphs of samples from AFM images. The predicted graphs contain not only atoms and their bond connections but also their coordinates within the image and elemental identification. The model is shown to be effective on simulated AFM images, but we also highlight some issues with robustness that need to be addressed before generalization to real AFM images.

Impact statement
Developing better techniques for imaging matter at the atomic scale is important for advancing our fundamental understanding of physics and chemistry as well as providing better tools for materials R&D of nanotechnologies. State-of-the-art high-resolution atomic force microscopy experiments are providing such atomic-resolution imaging for many systems of interest. However, greater automation of processing the measurement data is required in order to eliminate the need for subjective evaluation by human operators, which is unreliable and requires specialized expertise. The ability to convert microscope images into graphs would provide an easily understandable and precise view into the structure of the system under study. Furthermore, a graph consisting of a discrete set of objects, rather than an image that describes a continuous domain, is much more amenable to further processing and analysis using symbolic reasoning based on physically motivated rules. This type of image-to-graph conversion is also relevant to other machine learning tasks such as scene understanding.

Examine the subject matter with a deeper intention, using the perspective of Jaques Derrida's 'deconstruction' as a frame of mind as well as a framework. This study uses a qualitative approach with a descriptive-critical method specification. The study results show that the pandemic determines how to interact and communicate, even the way citizens exist. The pandemic also gave birth to more significant social problems, namely mass hysteria; A reflection or reflection of the character of the spectacle society. The pandemic presents a new social pathology known as the information pandemic. This pandemic creates images of terror that cause people to be more afraid, frustrated, and stressed because they multiply the fear and trauma in their minds. Prosperous countries practice Panopticon. A gentle and impressive power technique. Discourses, legal codes, norms, rules as well as rituals and symbols displayed by the state apparatus are another power strategy, which is referred to as symbolic violence.Penelitian ini bertujuan mengungkap makna-makna tersembunyi atau terpinggirkan dalam metanarasi Pandemi Covid-19.

Politik sebagai Dakwah: Komunikasi Politik Partai Keadilan Sejahtera (PKS)
Authors: Suryana Cecep 
Published: July 2022

This paper describes the dynamics of political communication run by the Partai Keadilan Sejahtera (PKS), which has been identified as a da’wa party. By using the phenomenological method, this paper describes the knowledge and experience of political communication which is framed as an Islamic da’wa movement which is the character of the PKS struggle which is focused on the concept of PKS da’wa and how political communication activities are carried out. This study shows that the PKS da’wa concept is inspired by Hasan Al-Banna’s universalist thought and da’wa movement because da’wa must be a practical answer to all social problems for all mankind, not only for Muslims. Therefore, politics is nothing but a medium of da’wa. Meanwhile, the pattern of political communication carried out by PKS is categorized into two categories, namely; communication to cadres, generally through Islamic and political studies; and communication in the context of succession or facing regional elections which are usually carried out through social service activities, public recitations and door to door socialization. Tulisan ini menguraikan tentang dinamika komunikasi politik yang dijalankan oleh Partai Keadilan Sejahtera (PKS) yang diidentifikasi sebagai partai yang berorientasi dakwah. Menggunakan metode fenomenologi, tulisan ini menguraikan tentang pengetahuan dan pengalaman komunikasi politik yang dikerangka sebagai gerakan dakwah Islam yang menjadi karakter perjuangan PKS yang difokuskan pada konsep dakwah PKS dan bagaimana aktivitas komunikasi politik yang dijalankan. Kajian ini menunjukkan bahwa konsep dakwah PKS banyak mendapat inspirasi dari gerakan dan pemikiran dakwah Hasan Al-Banna yang bersifat universalis dalam arti bahwa dakwah harus mampu menjadi jawaban praktis atas semua persoalan sosial-kemanusiaan, tidak hanya bagi umat Islam. Oleh karena itu, politik tidak lain merupakan salah satu medium dakwah. Sementara itu, pola komunikasi politik yang dijalankan oleh PKS dikategorikan pada dua kategori besar yakni; komunikasi terhadap kader yang pada umumnya melalui kajian-kajian Islam dan politik; dan komunikasi dalam konteks suksesi atau menghadapi perhelatan pilkada yang biasanya dilakukan melalui kegiatan bakti sosial, pengajian umum dan sosialisasi secara door to door.

Published: July 2022

Media literacy is a necessity for people who live in the midst of the development of communication technology. The overflow of information, and easy access to media, require the provision and strength to filter and criticize any content received by the public. By using descriptive methods, this study aims to determine how counselling communication can improve media literacy in the people of Desa Bojong Tengah, Kecamatan Pusakajaya, and Kabupaten Subang. The results showed that village government officials institutionally guide community leaders, community leaders informally and personally guide farmer groups, teachers guide formally guide students at school, and parents guide their children in a persuasive and coercive manner. The results of this study are expected to have an impact on the government in making regulations in increasing the importance of media literacy in the community and school environment. Then it has an impact on the formation of a special team that conducts media literacy counselling in each region.
