Authors: Panda Ananya , Sharma Akash , Dundar Ayca , Packard Ann , Aase Lee , Kotsenas Amy , Kendi Ayse Tuba
Published: September 2021

Background

There is scant insight into the presence of nuclear medicine (NM) and nuclear radiology (NR) programs on social media.

Objective

Our purpose was to assess Twitter engagement by academic NM/NR programs in the United States.

Methods

We measured Twitter engagement by the academic NM/NR community, accounting for various NM/NR certification pathways. The Twitter presence of NM/NR programs at both the department and program director level was identified. Tweets by programs were cross-referenced against potential high-yield NM- or NR-related hashtags, and tabulated at a binary level. A brief survey was done to identify obstacles and benefits to Twitter use by academic NM/NR faculty.

Results

For 2019-2020, 88 unique programs in the United States offered NM/NR certification pathways. Of these, 52% (46/88) had Twitter accounts and 24% (21/88) had at least one post related to NM/NR. Only three radiology departments had unique Twitter accounts for the NM/molecular imaging division. Of the other 103 diagnostic radiology residency programs, only 16% (16/103) had a presence on Twitter and 5% (5/103) had tweets about NM/NR. Only 9% (8/88) of NM/NR program directors were on Twitter, and three program directors tweeted about NM/NR. The survey revealed a lack of clarity and resources around using Twitter, although respondents acknowledged the perceived value of Twitter engagement for attracting younger trainees.

Conclusions

Currently, there is minimal Twitter engagement by the academic NM/NR community. The perceived value of Twitter engagement is counterbalanced by identifiable obstacles. Given radiologists’ overall positive views of social media’s usefulness, scant social media engagement by the NM community may represent a missed opportunity. More Twitter engagement and further research by trainees and colleagues should be encouraged, as well as the streamlined use of unique hashtags.
Examining How Internet Users Trust and Access Electronic Health Record Patient Portals: Survey Study
Authors: Yin Rong , Law Katherine , Neyens David
Published: September 2021

Background

Electronic health record (EHR) patient portals are designed to provide medical health records to patients. Using an EHR portal is expected to contribute to positive health outcomes and facilitate patient-provider communication.

Objective

Our objective was to examine how portal users report using their portals and the factors associated with obtaining health information from the internet. We also examined the desired portal features, factors impacting users’ trust in portals, and barriers to using portals.

Methods

An internet-based survey study was conducted using Amazon Mechanical Turk. All the participants were adults in the United States who used patient portals. The survey included questions about how the participants used their portals, what factors acted as barriers to using their portals, and how they used and how much they trusted other web-based health information sources as well as their portals. A logistic regression model was used to examine the factors influencing the participants’ trust in their portals. Additionally, the desired features and design characteristics were identified to support the design of future portals.

Results

A total of 394 participants completed the survey. Most of the participants were less than 35 years old (212/394, 53.8%), with 36.3% (143/394) aged between 35 and 55 years, and 9.9% (39/394) aged above 55 years. Women accounted for 48.5% (191/394) of the survey participants. More than 78% (307/394) of the participants reported using portals at least monthly. The most common portal features used were viewing lab results, making appointments, and paying bills. Participants reported some barriers to portal use including data security and limited access to the internet. The results of a logistic regression model used to predict the trust in their portals suggest that those comfortable using their portals (odds ratio [OR] 7.97, 95% CI 1.11-57.32) thought that their portals were easy to use (OR 7.4, 95% CI 1.12-48.84), and frequent internet users (OR 43.72, 95% CI 1.83-1046.43) were more likely to trust their portals. Participants reporting that the portals were important in managing their health (OR 28.13, 95% CI 5.31-148.85) and that their portals were a valuable part of their health care (OR 6.75, 95% CI 1.51-30.11) were also more likely to trust their portals.

Conclusions

There are several factors that impact the trust of EHR patient portal users in their portals. Designing easily usable portals and considering these factors may be the most effective approach to improving trust in patient portals. The desired features and usability of portals are critical factors that contribute to users’ trust in EHR portals.
Adapting a Mental Health Intervention for Adolescents During the COVID-19 Pandemic: Web-Based Synchronous Focus Group Study
Authors: Calvo-Valderrama Maria Gabriela , Marroquín-Rivera Arturo , Burn Erin , Ospina-Pinillos Laura , Bird Victoria , Gómez-Restrepo Carlos
Published: September 2021

Background

Although focus groups are a valuable qualitative research tool, face-to-face meetings may be difficult to arrange and time consuming. This challenge has been further compounded by the global COVID-19 pandemic and the subsequent lockdown and physical distancing measures implemented, which caused exceptional challenges to human activities. Online focus groups (OFGs) are an example of an alternative strategy and require further study. At present, OFGs have mostly been studied and used in high-income countries, with little information relating to their implementation in low- and middle-income countries (LMICs).

Objective

The aim of this study is to share our experiences of conducting OFGs through a web conferencing service and provide recommendations for future research.

Methods

As part of a broader study, OFGs were developed with adults and adolescents in Colombia during the COVID-19 pandemic. Through a convenience sampling method, we invited eligible participants via email in two different cities of Colombia to participate in OFGs conducted via Microsoft Teams. Researcher notes and discussion were used to capture participant and facilitator experiences, as well as practical considerations.

Results

Technical issues were encountered, but various measures were taken to minimize them, such as using a web conferencing service that was familiar to participants, sending written instructions, and performing a trial meeting prior to the OFG. Adolescent participants, unlike their adult counterparts, were fluent in using web conferencing platforms and did not encounter technical challenges.

Conclusions

OFGs have great potential in research settings, especially during the current and any future public health emergencies. It is important to keep in mind that even with the advantages that they offer, technical issues (ie, internet speed and access to technology) are major obstacles in LMICs. Further research is required and should carefully consider the appropriateness of OFGs in different settings.

Authors: Pandey Aparna
Published: September 2021

Abstract: Machine to Machine (M2M) communication is used to maintain the connectivity between the various devices in IoT. One of the major issues of Machine to Machine (M2M) communications is to enhance the network lifetime with the help of an efficient MAC protocols. Slotted ALOHA Protocol is simple random access technique used in low power applications like LoRaWAN (Long Range Wireless Area Network). This approach gives an improved result as compared to P-persistence slotted ALOHA. In this paper, we consider an IoT -M2M network comprises of a large no of devices that transmit data packets to a gateway. We have tried to reduce the collision, which directly reduce retransmission of data packets. We propose Adaptive pSlotted ALOHA Protocol using Successive Interference Cancellation (SIC). It offers high throughput and reduces the delay. It is the simplest way of the channel allotment among the users. The proposed p-Slotted ALOHA protocol using SIC is better than the p-persistence slotted ALOHA in term of delay and throughput. Keywords: MAC, M2M, Slotted ALOHA, LoRa-WAN, IoT, SIC

Published: September 2021

Kepekaan terhadap brand awareness dan brand identity sangat mempengaruhi pertumbuhan penjualan produk. Terutama untuk produk lokal yang berpotensial seperti roti ketawa. Roti ketawa merupakan makanan khas Siantar, Sumatera Utara yang sampai saat ini masih dijual dengan cara konfensional dengan pengemasan yang sederhana. Roti ketawa selama ini hanya dikenal masyarakat lokal, terutama di wilayah Sumatera Utara saja. Hal ini disebabkan karena lemahnya visual branding dan kurangnya inovasi dari segi kemasan dan pemasaran itu sendiri. Image roti ketawa sendiri pun semakin meredup akibat banyaknya kompetitif makanan serupa yang didominasi oleh kalangan artis dan memiliki kemasan yang lebih menarik. Potensi yang dimiliki oleh roti ketawa sangat besar untuk masuk ke market anak-anak muda. Untuk itu perlu dilakukan pendekatan yang moderen agar produk kuliner ini dapat diterima oleh target audience.Untuk itu penulis merancang strategi visual kreatif untuk memberikan melakukan visual branding terhadap produk kuliner roti ketawa dengan brand name “kekeh”.

Computer simulations for the teaching of photoelectric effect
Authors: Aurora Favero Reis Mari , Geller Marlise , Serrano Agostinho
Published: September 2021

The photoelectric effect in the production and transformation of light is animportant phenomenon in quantum physics. The theory was initially presented by Albert Einstein and allows us to explain several technological applications in engineering. The use of computer simulations in the process, as they have already been proven to yield in science teaching, can provide excellent conceptual learning results, and that includes the teaching of the photoelectric effect. Ten simulations available on the internet were classified by criteria established based on bibliographic research developed within the framework of the historicity, concept, and context triad, and then four were selected and used in a classroom with engineering undergraduate sophomores. The Predict-Observe-Explain (P.O.E.) methodology was used to guide students in carrying out the experiments. The results of the analysis of the simulations and the elaboration of a laboratory instruction guide and experimental intervention, with the methodology, demonstrated the effectiveness of using computer simulations for the learning of scientific concepts in the context of engineering education.

The proof or validity of a test toda is very difficult to arrive at categorically, considering the enormous difficalty of carrying out the tests and, the limited experience in statistically valid clinical evaluation. He concludes that it seems rarional to evaluate new materials which appear in the dental field, initialy according to specifications already existing for materials, wich the new material may eventually suplant or be employed as substitute.
Causation Research on Diabetic Foot Complications—What I Learned From Roger Pecoraro: The 2021 Roger E. Pecoraro Award Lecture
Authors: Boyko Edward J.
Published: September 2021

Roger Pecoraro made important contribution
to diabetic foot research and is primarily responsible for instilling in me an
interest in these complications. Our collaboration in the final years of his
life led to the development of the Seattle Diabetic Foot Study. At the time it
began, the Seattle Diabetic Foot Study was perhaps unique in being a
prospective study of diabetic foot ulcer conducted in a non-specialty primary
care population of patients with diabetes and without foot ulcer. Important
findings from this research include the demonstration that neurovascular
measurements, diabetes characteristics, past history of ulcer or amputation,
body weight, and poor vision all significantly and independently predict foot
ulcer risk. A prediction model from this research that included only readily
available clinical information showed excellent ability to discriminate between
patients who did and did not develop ulcer during follow-up (area under ROC
curve=0.81 at one year). Identification of limb-specific amputation risk
factors showed considerable overlap with those risk factors identified for foot
ulcer, but suggested arterial perfusion as playing a more important role. Risk
of foot ulcer in relation to peak plantar pressure estimated at the site of the
pressure measurement showed a significant association over the metatarsal
heads, but not other foot locations, suggesting that the association between
pressure and this outcome may differ by foot location. The Seattle Diabetic
Foot Study has helped to expand our knowledge base on risk factors and
potential causes of foot complications. Translating this information into
preventive interventions remains a continuing challenge.

Photovoltaics convert solar radiation into electrical current. For the present study, blends containing electron donor and acceptor are used instead of materials made with silicon. Carbon-based organic semiconductors are easy to process and have low fabrication costs. There are several fabrication steps playing important role in the photovoltaic device performance such as, substrate preparation, polymer-acceptor ratios in the blend, thermal annealing of the active layer and top electrode deposition. It has been shown that nanoscale morphology of the blend can be altered via thermal annealing treatment. As a result, efficiency is affected by surface roughness. The blend of P3HT: PCBM as donor: acceptor was used to fabricate thin films and photovoltaic cells. The power conversion efficiencies and surface morphologies of the devices annealed at various times were measured. Atomic force microscopy (AFM) images revealed that the surface roughness of the active layer is mainly affected by the annealing time, and the film with the roughest surface results in the most efficient solar cell.
A Review on Instructing English through Literary Genre
Authors: HAMIMED Nadia
Published: September 2021

This study aims to highlight the utilization of literary genre as a well-liked method for instructing both language skills (that is to say, writing, reading, speaking, and listening) and language fields (that are grammar, pronunciation, and vocabulary). Why employing literary textbooks in foreign language classrooms and the main motives for choosing appropriate fictional texts in these classrooms are emphasized to make the reader acquainted with the motivating incentives and standards for foreign language teachers’ employing and picking erudite textbooks. Additionally, the teaching of language skills and literary genre gains benefits of diverse fields of literature (like drama, poems, tragedy and tales) to language teaching and to several difficulties met by language teachers in the sphere of instructing English using fiction (i.e. shortage of training in the field of literature teaching English as a Second English and Teaching English as a Foreign Language curriculums, deficiency of precise aims describing the function of fiction in English as a Foreign Language and English as a Second Language, foreign language teachers’ not possessing the experience and preparation in literature, and lack of suitable teaching tools to be utilized by foreign language teachers in a class milieu) are taken into consideration.
Stylistic Portrait of English Fantasy Texts (Based on Jordan’s The Eye of the World, Martin’s A Game of Thrones, Rowling’s Harry Potter and the Philosopher’s Stone, and Harry Potter and the Chamber of Secrets)

The paper is focused on stylistic features of English fantasy texts. The research materials include four fantasy novels written by British and American authors of the late 20th century: Jordan’s The Eye of the World, Martin’s A Game of Thrones, Rowling’s Harry Potter and the Philosopher’s Stone, and Harry Potter and the Chamber of Secrets. The research question of the study lies in need to systematize expressive means and stylistic devices used in the texts and distinguish the common stylistic features of English fantasy texts. To do this, the researchers implement the notion of a stylistic portrait of English fantasy text, and the main aim of the paper is to provide its definition and description. The study employed the complex of linguistic research methods, including analysis and generalization of theoretical sources, contextual analysis and the elements of quantitative analysis of linguistic units used in the texts. Based on three essential aspects of a stylistic portrait, the paper shows that the English fantasy texts are characterized by the dominance of expressive means and stylistic devices at the syntactic level of language. In addition, the researchers identified the most productive stylistically marked linguistic units at each level of language correlated with the semantic field within which they functioned, and studied connotative dominants in these texts.

The importance of the study presented  is  by  effective development and management of any system, including the state, it is necessary to implement a set of strategic goals and objectives. The increasing pace of globalization and digitisation of the contemporary world determines the need for all countries to respond to modern challenges and risks. The stagnation of the economic trend caused by the spread of coronavirus infection COVID-2019 and the decrease in the quality of life of the population, the growth of environmental, technological, demographic and other problems are related to such threats. The search for answers so necessary to overcome global challenges in general determines the national security of any country and, in particular, its development and prosperity. The authors of the article proved that it is possible to find the necessary answers only in the framework of the formation of a new model of state development. This model should ensure the strengthening and development of the real sector of the economy, the creation of new growth points from the introduction of innovative technologies and investment activities.

The article aims to study the specificities of an individually differentiated approach in the formation of speech generalization semantics and communicative competence in older preschool children. The main approach to the study of this problem is the analysis of theoretical and methodological approaches in the study of an individually differentiated approach to the linguistic competence of preschool children, which allows us to identify the most effective ones.  The article focuses on the concepts of individualization and differentiation in the development of the semantic aspect of speech and communicative competence, taking into account the individual psychological characteristics of the children. It is concluded that an individually differentiated approach increases the effectiveness of measures to form linguistic competence in the system of semantics of generalization of discourse. The materials of the article can be useful for speech therapists, specialists in preschool institutions that work in the area of speech development for older preschoolers, as well as for teachers in search of effective technologies for the formation of language skills.
