The aim of this paper is to integrate security and privacy in mmWave communications. MmWave communication mechanism access three major key components of secure communication (SC) operations. proposed design for mmWave communication facilitates the detection of the primary signal in physical (PHY) layer to find the spectrum throughput for primary user (PU) and secondary user (SU). The throughput of SC for PU with maximum throughput being recorded at 0.7934 while maximum throughput for SU is recorded at 0.7679. So, we will design a mmWave communication mechanism for solving this problem. The probability for sensing where the probability of detection (PD) is predicted at a defined range of 690 km with an estimated accuracy of 83.56% while the probability of false alarm (PFA) is predicted at a defined range of 230 km with an estimated accuracy of 81.39%. This conflicting but interrelated issue is investigated over three stages for the purpose of solving with a cross-layer model with MAC and PHY layers for a secure communication network (SCN) while reducing the collision effect concurrently with a 92.76% for both cross-layers. MATLAB 2019b would be forwarded in use as the increasing demand for augmenting the bandwidth in secure communications has actuated the evolutionary technology.

Empirical research revealed that teaching quality is extremely important for the development of students’ employability attributes. Hence, one of the biggest challenges for HEI is to continuously improve teaching quality with the aim to enhance student employability. This study examined the influence of teaching quality on the employability of Technology Management students. Three important factors for teaching quality are identified from literature review comprising of learner quality, learning environment quality and content quality. This study used quantitative method to collect data via online questionnaire with 60 Technology Management students from a Business School within Malaysia responded. Data collected was analyzed using SPSS in term of normality, reliability, descriptive and Pearson correlation test. Finding from this study reveals that learning environment quality, content quality and learner quality are important, significant and positively correlated with employability. The main implication of this study is students’ employability could be assessed based on teaching quality directly instead of via students’ academic performance or employability attribute.
The use of peer role-play in doctor-patient communication skills training for medical students: A systematic review
Authors: Stevanny Bella , Syakurah Rizma Adlia
Published: August 2022

The quality of communication is directly related to patient satisfaction and can influence health outcomes. However, most doctors still have poor communication skills. A systematic literature search in PubMed, Cochrane, and Science Direct was conducted to retrieve studies reporting the use of peer role-play (PRP) for doctor-patient communication skills training in medical students. The quality of each study was assessed using the Joanna Briggs Institute (JBI) critical appraisal checklist. A total of 1,620 studies were obtained from electronic database search and screening of reference lists. After removing irrelevant studies and duplicates, one randomized control trial (RCT) and eight quasi-experimental studies were included in this systematic review. Peer role-play was perceived to be as useful as simulated patients (SP) training methods with comparable post-intervention objective structured clinical examination (OSCE) scores. Majority of students preferred PRP for learning communication skills over didactic lectures. The limitation of this review is the scarcity of eligible studies, high variability in the PRP programs across studies, and the lack of grey literature included. Peer role-play might be a cost-effective method to improve doctor-patient communication skills with comparable results (student’s perception and OSCE scores) with the expensive use of simulated patients. However, further study is needed to support this statement.

Published: August 2022

Environmental literacy is an attitude and behavior that must be possessed by a student in protecting the environment. Therefore, it is necessary to carry out a plan and action to empower environmental literacy through education. This study aimed to determine the effect of the problem-based learning with environmental-based comic (PBLEC) model in empowering students' environmental literacy in Indonesia. This type of research was a quasi-experimental posttest-pretest non-equivalent control group design study involving 97 students at the University of Muhammadiyah Makassar, South Sulawesi, Indonesia. Students' environmental literacy data was obtained by using an exam technique using an essay test instrument sheet, then the results were analyzed using descriptive statistics and one-way inferential analysis of covariance (ANCOVA). The results of statistical analysis showed that the PBLEC model has an effect on students' environmental literacy. The average score achieved by students in the class group using PBLEC is higher than students who are taught by the problem-based learning (PBL) learning process and conventional learning. Therefore, the use of the PBLEC model can be used in the learning process as an effort to grow and improve student environmental literacy.

Authors: Padagas Reynold , Duay Butch Stephen , Dalisay Jill
Published: August 2022

The internet-dense ecosystem has dramatically influenced the health-seeking behaviors of various population groups, including education students. Exposure to massive and readily accessible online health information increases health anxiety resulting in cyberchondria, a phenomenon characterized by excessive health search on the internet. This cross-sectional research study examined the level of cyberchondria among 179 teacher education students. The findings revealed that excessiveness, distress, reassurance, and compulsion subscales of cyberchondria were at moderate levels. However, higher correlations existed between excessiveness and compulsion subscales and between distress and compulsion subscales. Gender and programs enrolled have very weak relationships with cyberchondria subscales. The weakest association was between the programs enrolled by the students and all cyberchondria subscales. Meanwhile, students' age and year level have slightly higher but weak associations to the cyberchondria subscales, especially the excessiveness and distress subscales. As an intervention, an interdisciplinary collaboration between teacher education programs and the health-related institutes is recommended to promote awareness about cyberchondria, its prevention, and management.

The issue of professional English as a foreign language (EFL) lecturer in the industrial revolution 4.0 (IR 4.0) era has received considerable attention. However, very few studies on this subject have been conducted in Indonesia, particularly at State Islamic Universities. To address this gap, researchers conducted a qualitative study to examine how EFL lecturers maintain their professionalism in the IR 4.0 era and the curriculum approach that best meets current teaching and learning needs. The researchers applied a purposive sampling approach in selecting the participants for this study. There were 11 EFL lecturers from a state Islamic university in Banda Aceh, Indonesia chosen to participate in this study. The findings of this study indicate that EFL lecturers must continue to learn and improve their digital and technological competency in order to maintain their professionalism. In terms of curriculum approach, EFL lecturers believe that taking an interdisciplinary approach and providing more opportunities for students to focus on applied skills are essential parts of their teaching professionalism in the IR 4.0 era.

Published: August 2022

The article examines conditions for effective implementation of self-learning program in the training preschool teachers. The following research methods were used: pedagogical experiment, testing, observation, activity analysis, Kolmogorov-Smirnov test, Student’s t-test. An independent variable of the experiment was the self-learning program of preschool teachers developed through quality feedback and self-analysis. The professional competence of preschool teachers is studied through a system of components: motivational, cognitive, activity and reflective. Motivational and reflective components are less developed than cognitive and activity ones. It was found that the self-learning program is more effective for the development of cognitive, activity and reflective components, while the motivational component was less developed. It is established that the basic conditions for the effectiveness of professional self-learning is feedback from the program developer and ensuring quality pedagogical reflection of one’s actions. The following blocks of material were the most problematic for the assimilation of in the developed course: the physiological characteristics of children, speech and thinking of preschoolers, various aspects of the organization of learning and play in preschool education. The data can be used in the self-learning practice of preschool teachers and students to stimulate professional development. Further prospects for the study of the problem include improving the self-learning program for implementation in higher educational institutions. It is important to optimize the ways of development of preschool teachers’ pedagogical reflection. The development of standardized forms of assessment of acquired competencies is worth noting.

Published: August 2022

Most of the young generation do not realize the importance of decision making, money-saving, and budget planning. Consequently, a total of 47% of bankruptcies in Malaysia occurred among young adults between the ages of 18-35. Young individuals account for the majority of bankruptcies, public awareness of financial literacy should be raised. More effective teaching in secondary school has attracted researchers' attention. One of the general objectives of the Malaysian curriculum for the students is to practice moral values. Money-saving can be considered as one of the moral values. Still, school teachers have to cover many other academic topics, and they always feel overburdened with all types of examination-oriented textbooks. Students' value towards money and attitude influence their financial decision. Other factors needed in financial literacy are decision-making and accountability. This study aimed to examine factors that influence students' human values in financial literacy. This study had instilled human values to encourage students to practice time-saving, decision making, money-saving, and other values related to their well-being in the future. The survey was employed in this study. Then, a video that integrated financial literacy and human values with a Malaysian-based real-world learning experience was created in stage two. In addition, the questionnaire was administered to 327 secondary school students after they watched the video. The structural equation modeling method was used to determine the factors that influenced the financial literacy model. The findings from the analysis retained four elements: practices, decision making, accountability, and human values. Future research can focus on a comparative analysis with neighboring countries.

Published: August 2022

Student-centered teaching methods and technology are often viewed as effective tools to raise students’ performance and interest in mathematics learning. Limited research exists on discussion of teaching methods and the use of technology on the general certificate of education (GCE) A-level mathematics. The purpose of this qualitative research where data were collected using semi-structured interviews was to explore how A-level mathematics teachers used teaching methods and technology for the delivery of mathematics instruction. Convenience sampling was applied, the participants were seven A-level teachers from a private college in Johor, Malaysia. The gathered responses were analyzed using thematic analysis based on the approaches suggested by Braun and Clarke. The findings of this research reported that while mathematics teachers revealed they made some attempts in incorporating technology and student-centered teaching approaches to their classes, traditional teaching approaches such as chalk-and-talk and drill-and-practices remained to be the dominant teaching approaches they would use in their classes. In order to have a closer examination between the relationship of students’ interest and students’ performance in mathematics, the researcher suggests the future direction of study on the development of a teaching module which serves as a reference guide to alleviate the mentioned teachers’ concerns.

A visão educacional do Mestre Xun: tradução comentada do primeiro capítulo do Xúnzi 荀子
Authors: Costa Matheus Oliva da , Li Peter
Published: August 2022

No presente texto buscamos estudar um importante autor da formação da Escola dos Eruditos, também conhecida como Confucionismo. Trata-se da obra Xúnzi 荀子, do autor homônimo, que aportuguesamos como “mestre Xun” (310-211 AEC). Buscamos responder qual é a importância e o papel da questão do Aprender na obra do mestre Xun, ou seja: qual é sua visão educacional? Isso é importante não apenas pela importância dele nessa tradição que influenciou grande parte da humanidade, especialmente na Ásia, como também por ele contribuir à compreensão de boa parte do pensamento chinês antigo em geral, e de fornecer ideias sobre educação que podem ser importantes à todos interessados(as) nesse tema. Nosso objeto de estudo é o primeiro capítulo da obra do mestre Xun, chamado de “Quàn Xué 勸學, Persuadir a Aprender”. O objetivo é mostrar a visão educacional desse autor em seus próprios termos e à luz dos nossos comentários. Para isso, nosso método foi traduzir a partir dos princípios de fidelidade (xìn 信) ao original, inteligibilidade (dá 達) segundo as normas, e da elegância (yǎ 雅) da escrita e da compressão, seguido de comentários nossos. Nestes últimos usamos tanto um ponto de vista tradicional (confuciano e de explicação de cada paragrafo) quanto por recentes obras universitárias do tema. Em conclusão, mostramos que o Apender para o mestre Xun é o fundamento para a plena realização humana, em termos cognitivos, morais e socioemocionais, dentro dos parâmetros confucianos da busca por ser alguém Sábio.
Elementos para a Compreensão da Pintura de Paisagem Chinesa
Authors: Ribeiro Claudia
Published: August 2022

No sentido de promover a compreensão da pintura tradicional chinesa – sobretudo a pintura de paisagem – procuro discorrer sobre os seus aspectos materiais, técnicos e filosóficos. Começo precisamente pela incompreensão de que tem sido vítima, patente desde os primeiros missionários cristãos na China. Discrimino os vários materiais com ela relacionados, desde os mediums aos suportes e enumero os mais importantes tipos de pinceladas que fazem parte do seu vocabulário básico. De seguida, debruço-me sobre os seis grandes preceitos fundamentais para a execução e apreciação de pintura chinesa. Passo então a analisar as diversas características patentes numa obra de arte de pintura chinesa de paisagem, começando pela importância do espaço vazio e pelo jogo do yin e do yang com ele intimamente associado, seguindo-se a discreção ou insipidez, a fluência, a perspectiva não-linear e a recusa de mimesis. Por fim, delineio um breve périplo pela história da pintura chinesa, não só de paisagem mas de outros géneros também, realçando a diversidade e o tipo de criatividade que lhe são próprios.

Published: August 2022

A presente pesquisa tem como objetivo identificar a presença de práticas xamânicas na China antiga. Através das fontes selecionadas, apontadas situações em que são notas práticas entendidas como “xamanismo” de acordo com a bibliografia selecionada. A delimitação do conceito de “xamanismo” é fundamental para este trabalho. Estudiosos como Mircea Eliade e Kwang-chih Chang revelam uma ampla definição que esse termo expressa. Noções convencionais de ritos como práticas religiosas caminham ao lado de normas de comportamento e etiqueta, além de instituições e práticas implementadas por figuras virtuosas do passado. Além disso, as fontes textuais dão indícios de um forte vínculo do xamanismo com a autoridade política no recorte temporal selecionado. No decorrer da pesquisa, através das fontes selecionadas e com apoio bibliográfico, será identificado o aparecimento do xamanismo chinês e seu processo de transformações até chegar em seu auge, em que é incorporado pelas instituições dinásticas.

Crowd-Sourced Identification of Characteristics of Collective Human Motion
Authors: Amos Martyn , Webster Jamie
Published: August 2022

Crowd simulations are used extensively to study the dynamics of human collectives. Such studies are underpinned by specific movement models, which encode rules and assumptions about how people navigate a space and handle interactions with others. These models often give rise to macroscopic simulated crowd behaviours that are statistically valid, but which lack the noisy microscopic behaviours that are the signature of believable real crowds. In this article, we use an existing Turing test for crowds to identify realistic features of real crowds that are generally omitted from simulation models. Our previous study using this test established that untrained individuals have difficulty in classifying movies of crowds as real or simulated, and that such people often have an idealised view of how crowds move. In this follow-up study (with new participants) we perform a second trial, which now includes a training phase (showing participants movies of real crowds). We find that classification performance significantly improves after training, confirming the existence of features that allow participants to identify real crowds. High-performing individuals are able to identify the features of real crowds that should be incorporated into future simulations if they are to be considered realistic.
Prescribed Performances: Fluxus and Disability
Authors: Chamberlain Colby
Published: August 2022

In 1961, George Maciunas first met the artists and composers whom he would organize into the neo-avant-garde movement known as Fluxus. That same year, he acquired a persistent cough that was later diagnosed as asthma. Drawing from disability-studies scholars including Alison Kafer, Rosemarie Garland-Thomson, Jasbir K. Puar, and Ellen Samuels, “Prescribed Performances” considers the historical dimensions of this coincidence. Maciunas belonged to a new class of medical subject, the patient of chronic illness who depended on postwar medical innovations (such as steroids) and integrated a regime of self-management into their everyday life. To chart where and how the subject presented in neo-avant-garde performance intersected with the one produced by an emerging biopolitical apparatus for regulating public health, this article turns to the first Fluxus concerts, held in Europe in 1962–63, and then moves forward into the 1970s, asking how event scores, multiples, happenings, and body art were all inflected by their authors' experiences of debility, gender, sexuality, race, nationality, and precarity. Maciunas's Solo for Sick Man (1962), FluxClinic (1966), One Year (1973–74), Hospital Event (1975–76), and Flux Wedding (1978) will be discussed in relation to works by George Brecht, John Cage, Hi Red Center, Allan Kaprow, Alison Knowles, Shigeko Kubota, Charlotte Moorman, Nam June Paik, and La Monte Young.

Authors: FERNANDEZ-HILARIO ROBIN , REYNEL CARLOS
Published: August 2022

Two new species of Meliosma, M. chanchamayensis and M. dazae, are described and illustrated from the Department of Junín of Peru. Meliosma chanchamayensis is more closely related to M. wurdackii but differs by its leaf blades (4.0-)5.0–7.2 cm wide, glabrous abaxial leaf blades, pedicels 0.5–0.8 mm long, and sepals 0.71–0.90 mm long. Meliosma dazae most closely resembles M. caballeroensis but differs by its elliptic leaf blades, sepals longer than outer petals, sepals 0.92–1.18 mm long, outer petals 0.66–0.95 mm long, and entire inner petals. Following IUCN criteria, M. chanchamayensis and M. dazae are categorised as Critically Endangered (CR).

Hydnobolites oaxacanus is described using molecular and morphological data. This new species is characterized by the whitish ascomata with orange spots, grey gleba, and 4-spored asci with ascospores of 17–45 × 15–20 µm. The new species differs from other American Hydnobolites such as H. californicum and H. cerebriformis by the number of ascospores per asci, and larger ascospore size and ornamentation. It is putatively associated with Quercus castanea in the Quercus-Pinus dry mixed forest. Photographs, descriptions, and molecular phylogeny of the ITS region are presented.
A new Sobralia (Orchidaceae: Sobralieae) from Panama

Published: August 2022

In Panama, the Orchidaceae comprise 187 genera, of which one of the most conspicuous is Sobralia. The flowers of Sobralia are mostly ephemeral but colorful, often fragrant, and of variable sizes. Despite being a prominent group, its taxonomy is still underdeveloped in most neotropical countries. To continue with taxonomic studies in the Orchidaceae of Panama, we investigated a species of Sobralia, which differs from any recorded species of the genus. We documented the species with digital images and compared it with morphologically similar taxa. This paper describes and illustrates a new Sobralia from the Bosque Protector Palo Seco in the Fortuna area, Panama. Sobralia rinconiana differs from all other species recorded in Panama by the combination of a large plant size that reaches up to 120 cm high and the larger and broader, elliptical-lanceolate leaves (30–35 × 14–16 cm). Sobralia rinconiana is most similar to S. carazoi but differs in the spreading flowers with reflexed petals and the infundibuliform, cream-yellow lip, the wider, longer sepals and petals, and the longer, suberect column. The accurate estimate of the number of Sobralia species in Panama is still uncertain. Its diversity may increase as new areas are explored or species complexes are resolved.
Application of viscoelastic-plastic model in blended yarn
Authors: Peng Laihu , Zheng Qiuyang , Li Yang , Hu Xudong
Published: August 2022

This paper investigates the mechanical properties of a blended yarn and its correlation with the characteristics of constituent yarns of different materials. Each yarn’s creep and stress relaxation tests are curves fitted to a six-element constitutive model. The results show that the higher the chemical fiber content in the yarn, the better the plastic properties. The experimental data fit the six-element model with 99% confidence. Compared with the commonly used viscoelastic Burgers and Ering models, the six-element model has a much more precise forecasting ability. Within the scope of this study, the ratio of yield stress to initial stress under different stress conditions calculated from the same yarn test is similar, and the ratio is only related to the blending ratio of polyester-cotton blended yarn. In yarns with strong plasticity, this ratio can reflect the proportional relationship between plastic deformation and elastic deformation in relaxation experiments.

Published: August 2022

Background:

Intra-articular microfragmented adipose tissue (MF-AT) injections have been proposed for the treatment of knee osteoarthritis (OA).

Purpose:

To compare a single injection of MF-AT or platelet-rich plasma (PRP) in terms of clinical outcomes and OA progression.

Study Design:

Randomized controlled trial; Level of evidence, 1.

Methods:

A total of 118 patients with symptomatic knee OA were randomized to receive a single intra-articular injection of MF-AT or PRP. Patients were evaluated before the injection and at 1, 3, 6, 12, and 24 months with the International Knee Documentation Committee (IKDC) subjective score, Knee injury and Osteoarthritis Outcome Score (KOOS) subscales, EuroQol visual analogue scale (EQ-VAS), EuroQol 5 dimensions (EQ-5D), and visual analogue scale (VAS) for pain. Primary outcomes were the IKDC subjective score and the KOOS pain subscore at 6 months. Knees were evaluated at baseline and at 6, 12, and 24 months with radiography and high-resolution magnetic resonance imaging (MRI) using the Whole-Organ Magnetic Resonance Imaging Score (WORMS).

Results:

Both MF-AT and PRP provided a statistically and clinically significant improvement up to 24 months. The improvement in the IKDC subjective score from baseline to 6 months was similar in both MF-AT (41.1 ± 16.3 to 57.3 ± 18.8) and PRP (44.8 ± 17.3 to 58.4 ± 18.1) groups ( P < .0005). The improvement in the KOOS pain subscore from baseline to 6 months was similar in both the MF-AT (58.4 ± 15.9 to 75.8 ± 17.4) and PRP (63.5 ± 17.8 to 75.5 ± 16.1) groups ( P < .0005). Overall, no differences were found between the MF-AT and PRP groups in terms of clinical outcomes, adverse events (18.9% and 10.9%, respectively), and failures (15.1% and 25.5%, respectively). Radiographic and MRI findings did not show changes after the injection. As a secondary outcome, more patients in the MF-AT group with moderate/severe OA reached the minimal clinically important difference for the IKDC score at 6 months compared with the PRP group (75.0% vs 34.6%, respectively; P = .005).

Conclusion:

A single intra-articular injection of MF-AT was not superior to PRP, with comparable low numbers of failures and adverse events and without disease progression. No differences were found in clinical and imaging results between the 2 biological approaches.
