Qualitative and quantitative gastric ultrasound assessment in highly skilled regional anesthesiologists

Background Pulmonary aspiration is a major complication in anesthesia, and various studies have shown that gastric sonography can reliably provide valuable information relative to both the qualitative and quantitative aspects of gastric content. This study aimed to determine the accuracy of ultrasound assessment of gastric content compared between two novice anesthesiologist gastric sonographers. Methods This prospective cohort study of two anesthesiologists learning to perform qualitative and quantitative ultrasound assessment of gastric content on healthy volunteers was conducted at Siriraj Hospital (Bangkok, Thailand). This trial was registered with ClinicalTrials.gov (reg. no. NCT04760106). Results Of the 50 enrolled participants, three were excluded due to study protocol violation. Each anesthesiologist performed a qualitative assessment on 47 participants for an overall total of 94 scans. There were 15 males and 32 females (age 42 ± 11.7 years, weight 61.2 ± 13.1 kg, height 160.7 ± 7.3 cm, and BMI 23.6 ± 4.3 kg/m2). The overall success rate for all gastric content categories was approximately 96%. From antral cross-sectional area measurement, as the ingested volume increased, there was a tendency toward increased deviation from the actual ingested volume. Interrater agreement between anesthesiologists was analyzed using intraclass correlation coefficients (ICCs). A larger fluid volume was found to be associated with a lower level of agreement between the two anesthesiologists. The ICCs were 0.706 (95% CI: −0.125 to 0.931), 0.669 (95% CI: −0.254 to 0.920), 0.362 (95% CI: −0.498 to 0.807) for the 100 ml, 200 ml, and 300 ml fluid volumes, respectively. The mean duration to perform an ultrasound examination for each gastric content category and for the entire examination did not differ significantly between anesthesiologists (p > 0.05). Conclusion Our results indicate that qualitative ultrasound assessment of gastric content is highly accurate and can be easily learned. In contrast, quantification of gastric volume by novice gastric sonographers is more complex and requires more training. Trial registration ClinicalTrials.gov no. NCT04760106 Date registered on Feb 11, 2021. Prospectively registered.

The Perceived Effectiveness of Student Engagement Strategies in Open and Distance Learning

Student engagement is critical in online learning because it makes students feel more satisfied and motivated to learn. This study investigated how university students perceive various engagement tactics employed in online courses during the Covid 19 pandemic. Student engagement was measured using Moore's interaction framework. It implemented non-experimental quantitative research design through a survey with descriptive and causal-comparative approaches. A 29-item survey on learner-to-learner, learner-to-instructor, and learner-to-content engagement strategies was completed by 181 students from School of Engineering at Universiti Teknologi MARA. The students considered learner-to-content interactions to be the most engaging technique, according to the research. Learner-to-instructor interactions were the next most engaging method, while learner-to-learner interactions were the least engaging. Additionally, the most engaging technique is for them to search for and select appropriate materials in the learner-to-content category depending on their interests. Working jointly using online communication technologies to accomplish case studies, projects, or reports was deemed the most interesting technique by students in the learner-to-learner category. In the learner-to-instructor category, an email reminder or periodical notification is likewise regarded as the most engaging method. All three engagement mechanisms were shown to be interrelated, with learner-to-learner interactions heavily influencing learner-to-learner interactions. Mechanical engineering students were shown to be better at perceiving and implementing these tactics than students from the colleges of electrical, chemical, and civil engineering. It is believed that the findings of the present study will assist teachers and lecturers in increasing their participation in online courses.

Danger, Sex, and Everything Else

This study tests the effects of camera distance and camera angle on emotional response across four categories of pictures covering a large emotional range (positive and negative miscellanea, erotica, and threat), using the International Affective Picture System (IAPS) –a large database of emotionally evocative photographs. We content analyzed 722 images for the content category and camera framing (distance and angle), employing these as independent factors in analyses, and used the IAPS’ pre-existing normative average ratings of emotional valence, arousal, and dominance as dependent variables. As hypothesized, affective responses were generally increased by closer framing and high and low angles (compared to straight angles), but the content of the picture played an important role in determining effect strength and direction. In particular, closeness increased arousal for all picture groups but had the opposite effect on positive miscellaneous pictures, straight angles decreased the emotional response for the two miscellanea groups, and low angles increased the emotional response for threatening pictures. This study is the first to show that previously found camera framing effects apply to pictures of high emotional intensity (e.g., erotica and threat). We suggest that future work should consider formal manipulations alongside message content.

Sustainability of Health and Fitness Information Platform Ecosystem

The roles of content producers, information receivers, and platform operators affect the stability of the governance of informational platforms. The purpose of this study was to identify and explore the sustainable factors of a platform ecosystem for health and fitness apps across Mainland China and Taiwan by interviewing producers, receivers, and operators. An advanced analytic hierarchy process (AHP) method was applied to derive expert perspectives from apps users and operators, live streamers, key opinion leaders, scholars, and officers across Mainland China and Taiwan via four dimensions and fourteen sub-dimensions of the initial health and fitness apps. The results revealed that the weights of the dimensions of health and fitness apps were sorted by content categories, content updates, user reviews, and platform terms; furthermore, the weights of the six highest sub-dimensions were the following: exercise, new feature, functionality, correctness, monitoring, and privacy. Content producers in Taiwan cared the most about the content category, whereas content producers in Mainland China cared the most about user reviews. Information receivers in Taiwan graded the content category the highest, whereas information receivers in Mainland China rated content updates the highest. Platform operators in Taiwan paid most attention to the platform terms, whereas the platform operators in Mainland China were most concerned with the content category. This comparative study can contribute to assisting the health and fitness industry across Mainland China and Taiwan area to provide an overall strategic operative process by identifying the effectiveness of the procedures, estimative processes, and cost reduction to enhance the competitiveness and further improve users’ experiences and satisfaction for the sustainability of health and fitness information platform Ecosystem.

The Ranking Prediction of NBA Playoffs Based on Improved PageRank Algorithm

It is of great significance to predict the results accurately based on the statistics of sports competition for participants research, commercial cooperation, advertising, and gambling profit. Aiming at the phenomenon that the PageRank page sorting algorithm is prone to subject deviation, the category similarity between pages is introduced into the PageRank algorithm. In the PR value calculation formula of the PageRank algorithm, the factor W(u, v) between pages is added to replace the original Nu (the number of links to page u). In this way, the content category between pages is considered, and the shortcoming of theme deviation will be improved. The time feedback factor in the PageRank-time algorithm is used for reference, and the time feedback factor is added to the first improved PR value calculation formula. Based on statistics from 1230 games during the NBA 2018-2019 regular season, this paper ranks the team strength with improved PageRank algorithm and compares the results with the ranking of regular-season points and the result of playoffs. The results show that it is consistent with the regular-season points ranking in the eastern division by the use of improved PageRank algorithm, but there is a difference in the second ranking in the western division. In the prediction of top four in playoffs, it predicts three of the four teams.

OCCUPATIONAL CHOICE AND CAREER/JOB SATISFACTION AMONG YOUNG SPECIALISTS

Background: Professional activity is an important component of self-realization. Career and job satisfaction contribute to greater productivity and a sense of success. The initial stage of professional self-determination is occupational choice. Therefore, it is important to understand how to choose a profession and experience a higher level of career and job satisfaction. Aim: the paper aims to study the parameters of occupational choice among young specialists associated with career and job satisfaction in the future. Materials and methods. The sample consisted of 48 respondents, both females and males, young specialists from various professional fields with work experience from 1 year to 3 years. The study was conducted by means of a structured interview followed by content analysis of the data obtained. Career and job satisfaction were studied through self-reporting of subjects. Statistical processing of the data was carried out using the Spearman rank correlation coefficient and the Mann–Whitney U-test in the SPSS Statistics program. Results. The parameters of occupational choice among young specialists were studied such as information saturation, emotional attractiveness, motives of choice, as well as their components. It was found that the “information saturation” parameter includes such elements as “information about the profession”, “knowledge of oneself”, “personal experience of acquaintance with the profession”. The “emotional attractiveness” parameter includes “professional interest” and “emotional attitude”. It was found that personal experience and emotional attractiveness are most closely associated with career and job satisfaction among young specialists. Reliance on motives from the “activity content” category is associated with greater career and job satisfaction, and reliance on motives from the “personal security” category is associated with less pronounced satisfaction in the future. Conclusion. Thus, it was possible to prove the relationship between occupational choice and the subsequent career and job satisfaction among young specialists.

Content analysis and characterization of medical tweets during the early Covid-19 pandemic

ABSTRACTObjectiveThe novel coronavirus disease 2019 (Covid-19) has infected millions worldwide and impacted the lives of many folds more. Many clinicians share new Covid-19 related resources, research, and ideas within the online Free Open Access to Medical Education (FOAM) community of practice. This study provides a detailed content and contributor analysis of Covid-19 related tweets among the FOAM community.Design, Setting, ParticipantsTwitter was searched from November 1st, 2019 to March 21st, 2020 for English tweets discussing Covid-19 in the FOAM community. Tweets were classified into one of 13 pre-specified content categories: original research, editorials, FOAM resource, public health, podcast or video, learned experience, refuting false information, policy discussion, emotional impact, blatantly false information, other Covid-19, and non-Covid-19. Further analysis of linked original research and FOAM resources was performed. 1000 randomly selected contributor profiles and those deemed to have contributed false information were analyzed.ResultsThe search yielded 8541 original tweets from 4104 contributors. The number of tweets in each content category were: 1557 other Covid-19 (18·2%), 1190 emotional impact (13·9%), 1122 FOAM resources (13·1%), 1111 policy discussion (13·0%), 928 advice (10·9%), 873 learned experience (10·2%), 424 non-Covid-19 (5·0%), 410 podcast or video (4·8%), 304 editorials (3·6%), 275 original research (3·2%), 245 public health (2·9%), 83 refuting false information (1·0%), and 19 blatantly false (0·2%).ConclusionsEarly in the Covid-19 pandemic, the FOAM community used Twitter to share Covid-19 learned experiences, online resources, crowd-sourced advice, research, and to discuss the emotional impact of Covid-19. Twitter also provided a forum for post-publication peer review of new research. Sharing blatantly false information within this community was infrequent. This study highlights several potential benefits from engaging with the FOAM community on Twitter.

Understanding Consumer Enchantment via Paranormal Tourism: Part I—Conceptual Review

Tourism-hospitality businesses sometimes market consumer experiences in terms of “enchantment,” although this phrase is often used vaguely or variously. Therefore, we approached the issue conceptually by examining prior research on the experience economy, extraordinary architectural experiences, and accounts of paranormal tourism. Our critical overview suggests that we are dealing with a phenomenon rooted in environment-person bidirectional (or enactive) effects. We subsequently argue for the term “situational-enchantment” to denote a distinct and progressive arousal state characterized by dis-ease or dissonance that facilitates a sense of connection or oneness with a “transcendent agency, ultimate reality, or Other.” An iterative Content Category Dictionary exercise based on target literature specifically mapped this hypothesized state in terms of five competing features: (a) Emotional, (b) Sensorial, (c) Timeless, (d) Rational, and (e) Transformative. We frame this phenomenology within Funder’s Realistic Accuracy Model, which we propose drives an epiphanic process involving attentional, perceptual, attributional, and social mechanisms. Our synthesis of the multidisciplinary literature in this domain helps to clarify the nature and relevance of enchantment as an individual difference that varies across people and is subject to a variety of contextual influences. Accordingly, we discuss how this hypothesized state can be manipulated to an extent within certain people by creating or reinforcing conditions that spur experiential and rational engagement with ambiguous or unexpected stimuli.

Perspectives of Platform Operators, Content Producers, and Information Receivers toward Health and Fitness Apps

The interactive mechanism among platform operators, content producers, and information receivers is increasingly complex in human–computer symbiosis. The purpose of this study is to identify the interactive value among platform operators, content producers, and information receivers with regard to information through the health and fitness apps by adopting an advanced Analytic Hierarchy Process (AHP) method derived from professional perspectives of app users and operators, key opinion leaders, scholars, and officers. The AHP method was allocated weightings to the evaluation criteria from the twelve panelists from three groups of platform operators, content producers, and information receivers. After focus group interviews were conducted, four dimensions and twelve sub-dimensions of the initial health and fitness apps were obtained as follows: Content category: Monitoring, exercise, journaling, and sleeping; (2) User reviews: Fuctionality, interactivity, and criticism; (3) Content updates: New feature, correctness, and new language; (4) Platform terms: Privacy, accuracy, ownership, and right of use. The study integrated the panelists’ opinions toward health and fitness apps and analyzed the weight of each indicator according to their importance by Power Choice V2.5. The results revealed that the weights of dimensions of health and fitness apps were sorted by content category, user review, platform terms, and content update, as well as that the weights of the top six sub-dimensions were followed: monitoring, exercise, functionality, interactivity, privacy, and accuracy. Content producers suggested increasing the popularity of their products by adding new features, whereas information receivers preferred to correct problems. Content producers and information receivers graded platform terms as less essential, whereas platform operators rated platform terms higher. This study can contribute to assisting the health and fitness industry and the overall strategic operative process by identifying how the effectiveness in the procedures, estimative process, and cost-down can enhance competitiveness to further improve users experience and satisfaction.
