Developing intercultural competence through drone-assisted virtual field trips while adapting to pandemic times

Abstract We designed technology-assisted intercultural learning activities in this study. University students, ten from Indonesia and ten from China recorded videos about local culture and traditions, and then they exchanged videos with partners to enable cultural virtual field trips. To record cultural videos, one has to personally go to places related to local culture and traditions; however, this was not a good idea due to the COVID-19 pandemic. To implement the physical distancing measures imposed by the COVID-19 pandemic, the participants employed drones or unmanned aerial vehicles (UAVs) to record cultural videos. This study explored the affordances of UAVs for intercultural learning and whether intercultural competence of the participants will be facilitated. Through our mixed-method approach, we collected the data from questionnaires, videos, and interviews. We obtained three main findings. First, we revealed five UAV affordances such as (1) UAVs convey visual and aural feelings of being in a place; (2) UAVs provide details on a circular route beyond the human eye-level; (3) UAVs provide landscape overviews; (4) UAVs provide detailed observations at higher altitudes or make surveillance possible, and (5) UAVs enable flying to a specific area. Second, drone-assisted intercultural learning activities facilitated intercultural competence of the Chinese and Indonesian participants. Based on the results of the study, we made several suggestions and drew implications for educators and researchers.
Arctic – Atlantic Exchange of the Dissolved Micronutrients Iron, Manganese, Cobalt, Nickel, Copper and Zinc With a Focus on Fram Strait

The Arctic Ocean is considered a source of micronutrients to the Nordic Seas and the North Atlantic Ocean through the gateway of Fram Strait (FS). However, there is a paucity of trace element data from across the Arctic Ocean gateways, and so it remains unclear how Arctic and North Atlantic exchange shapes micronutrient availability in the two ocean basins. In 2015 and 2016, GEOTRACES cruises sampled the Barents Sea Opening (GN04, 2015) and FS (GN05, 2016) for dissolved iron (dFe), manganese (dMn), cobalt (dCo), nickel (dNi), copper (dCu) and zinc (dZn). Together with the most recent synopsis of Arctic‐Atlantic volume fluxes, the observed trace element distributions suggest that FS is the most important gateway for Arctic‐Atlantic dissolved micronutrient exchange as a consequence of Intermediate and Deep Water transport. Combining fluxes from FS and the Barents Sea Opening with estimates for Davis Strait (GN02, 2015) suggests an annual net southward flux of 2.7 ± 2.4 Gg·a−1 dFe, 0.3 ± 0.3 Gg·a−1 dCo, 15.0 ± 12.5 Gg·a−1 dNi and 14.2 ± 6.9 Gg·a−1 dCu from the Arctic toward the North Atlantic Ocean. Arctic‐Atlantic exchange of dMn and dZn were more balanced, with a net southbound flux of 2.8 ± 4.7 Gg·a−1 dMn and a net northbound flux of 3.0 ± 7.3 Gg·a−1 dZn. Our results suggest that ongoing changes to shelf inputs and sea ice dynamics in the Arctic, especially in Siberian shelf regions, affect micronutrient availability in FS and the high latitude North Atlantic Ocean.
Assessment System for Predicting Maximal Safe Range for Heel Height by Using Force-Sensing Resistor Sensors and Regression Models

Women often wear high-heeled shoes for professional or esthetic reasons. However, high-heeled shoes can cause discomfort and injury and can change the body’s center of gravity when maintaining balance. This study developed an assessment system for predicting the maximal safe range for heel height by recording the plantar pressure of participants’ feet by using force-sensing resistor (FSR) sensors and conducting analyses using regression models. Specifically, 100 young healthy women stood on an adjustable platform while physicians estimated the maximal safe height of high-heeled shoes. The collected FSR data combined with and without personal features were analyzed using regression models. The experimental results showed that the regression model based on the pressure data for the right foot had better predictive power than that based on data for the left foot, regardless of the module. The model with two heights had higher predictive power than that with a single height. Furthermore, adding personal features under the condition of two heights afforded the best predictive effect. These results can help wearers choose maximal safe high-heeled shoes to reduce injuries to the bones and lower limbs.

Review on Wearable Thermoelectric Generators: From Devices to Applications

Wearable thermoelectric generators (WTEGs) can incessantly convert body heat into electricity to power electronics. However, the low efficiency of thermoelectric materials, tiny terminal temperature difference, rigidity, and neglecting optimization of lateral heat transfer preclude WTEGs from broad utilization. In this review, we aim to comprehensively summarize the state-of-the-art strategies for the realization of flexibility and high normalized power density in thermoelectric generators by establishing the links among materials, TE performance, and advanced design of WTEGs (structure, heatsinks, thermal regulation, thermal analysis, etc.) based on inorganic bulk TE materials. Each section starts with a concise summary of its fundamentals and carefully selected examples. In the end, we point out the controversies, challenges, and outlooks toward the future development of wearable thermoelectric devices and potential applications. Overall, this review will serve to help materials scientists, electronic engineers, particularly students and young researchers, in selecting suitable thermoelectric devices and potential applications.

Systemic Inflammation Is Associated With Future Risk of Fatal Infection: An Observational Cohort Study

Abstract Background Many diseases are associated with chronic inflammation, resulting in widening application of anti-inflammatory therapies. Although they are effective as disease-modifying agents, these anti-inflammatory therapies increase the risk of serious infection; however, it remains unknown whether chronic systemic inflammation per se is also associated with fatal infection. Methods Using serum C-reactive protein (CRP) data from 461 052 UK Biobank participants, we defined incidence rate ratios (IRRs) for death from infection, cardiovascular disease, or other causes and adjusted for comorbidities and the use of anti-inflammatory therapies. Results Systemic inflammation, defined as CRP ≥2 mg/L, was common in all comorbidities considered. After adjusting for confounding factors, systemic inflammation was associated with a higher IRR point estimate for infection death (1.70; 95% confidence interval [CI], 1.51–1.92) than cardiovascular (1.48; CI, 1.40–1.57) or other death (1.41; CI, 1.37–1.45), although CIs overlapped. C-reactive protein thresholds of ≥5 and ≥10 mg/L yielded similar findings, as did analyses in people with ≥2, but not <2, comorbidities. Conclusions Systemic inflammation per se identifies people at increased risk of infection death, potentially contributing to the observed risks of anti-inflammatory therapies in clinical trials. In future clinical trials of anti-inflammatory therapies, researchers should carefully consider risks and benefits in target populations, guided by research into mechanisms of infection risk.
CROWDFUNDING: AN INNOVATION IN THE AGE OF DIGITAL MARKETING

Entrepreneurs today establish the startups based on their own value chain using digital technology. Digital Marketing helps startups to focus attention of crowd through innovation and new marketing techniques. Crowdfunding is the collection of funds from people by marketing product / idea / startup online through internet platforms using digital technology. Crowdfunding is emerging as a billion dollar industry with funding opportunities available across platforms to entrepreneurs, organizations, and companies like Honda, Coca-Cola etc. Crowdfunding allows customers to fund for a product or cause themselves. Dell used this to fund the purchase of a laptop for college students. Honda used the platform of Indiegogo.com to raise funds for a project (social cause). KimberlyClark used this on moms to develop innovative products for children (FMCG product). The most famous crowdfunded product ‘Pebble Watch’ started pushing hard on the founders to make the watch waterproof (by the crowd) that the company had to add this feature before it closed the campaign. Smart brands have realized that crowdfunding provides focus groups online which help elevate the value n existence of their product. If any firms / organization or company wants to be at the forefront of digital cutting-edge integrated marketing tool it has to ‘innovate’. The paper tries to analyze crowdfunding as an opportunity for innovation in the digital age. It uses questionnaire to gather data from platform providers and startups to judge how important is digital technology for crowdfunding. It also lists certain pros and cons for crowdfunding in the age of digital marketing.
PENINGKATAN KINERJA SISTEM LMDS DENGAN ADAPTIVE CODED MODULATION MENGGUNAKAN RELAY AMPLIFY AND FORWARD DIBAWAH PENGARUH REDAMAN HUJAN TROPIS

Sistem LMDS (Local Multipoint Distribution Service) merupakan sistem komunikasi wireless yang dapat menyediakan layanan broadband dengan frekuensi operasi antara 28 – 31 GHz dengan teknik line of sight. Pemanfaatan lebar pita frekuensi yang sedikitnya sebesar 1 GHz membuat sistem LMDS mampu membawa informasi suara, video dan data berkecepatan tinggi dalam kapasitas yang besar. Meskipun demikian, cakupan sinyalnya terbatas pada radius antara 3 km hingga 5 km. Hal ini disebabkan karena karakteristik propagasi sinyal pada frekuensi tinggi banyak mengalami redaman, terutama redaman hujan. Selain itu adanya interferensi dari sel base station lain juga ikut mempengaruhi kinerja sistem LMDS. Untuk mengurangi pengaruh redaman hujan dan interferensi, pada penelitian ini dilakukan beberapa metode untuk meningkatkan kinerja sistem LMDS antara lain dengan teknik Adaptive Coded Modulation yang dikombinasikan dengan Relay Amplify and Forward. Berdasarkan hasil analisis yang telah dilakukan menunjukkan bahwa penggunaan teknik Adaptive Coded Modulation terhadap sistem LMDS yang menggunakan kanal dengan pengaruh redaman hujan dan interferensi dari sel lain baik pada pengamatan Bit Error Rate (BER) maksimal 10-6 maupun 10-11 diperoleh nilai link availability sistem mencapai 99,99% untuk panjang link utama 2 km pada sistem adaptif dan sistem 4 QAM non-adaptif. Bahkan hasil analisa sistem Adaptive Coded Modulation dengan Relay Amplify and Forwad diperoleh nilai link availabilty sistem mencapai 99,99% pada panjang link 4 km baik untuk sistem adaptif maupun sistem non-adaptif. Secara keseluruhan penggunaan teknik Adaptive Coded Modulation yang dikombinasikan dengan Relay Amplify and Forward menunjukkan peningkatan unjuk kerja Bit Error Rate (BER) dan efisiensi bandwidth sistem LMDS.
Volume analysis of cooling systems with synthetic jet actuator

: Increasing demands on the power and efficiency of electronic devices mean that more and more efficient methods of active cooling are being sought. One of the active cooling methods is the synthetic jet. The investigations show that the synthetic jet provides higher heat transfer enhancement than a continuous jet. But, in the papers, the size of the cooling devices is usually omitted. In this paper, the size of the chosen synthetic jet cooling system was investigated and compared to the size of the fan-cooled heat sink and heat sink under natural convection. Additionally, a comparison of the performance of different cooling devices was made. Investigation showed that the size of synthetic jet actuator cooling devices used is much bigger than the size of the fan-cooled heat sink, and therefore the heat sink heat transfer rate per unit temperature difference and unit volume of the cooling device is even 12 times lower than in case of the fan-cooled heat sink. Design challenges of cooled devices, which use synthetic jet actuators were presented.

Detection of paroxysmal atrial fibrillation in 994 patients with a cerebrovascular event by intermittent 21-day ECG-monitoring and 7-day continuous Holter-recording

Background The detection of paroxysmal atrial fibrillation (AF) is of importance in stroke care. The method used is continuous electrocardiogram (ECG)-monitoring or multiple short ECG-recordings during an extended period. Their relative efficiency is a matter of discussion. In a retrospective cohort study on 994 patients with an ischemic stroke or transient ischemic attack (TIA), we have compared continuous 7-day monitoring to intermittent recording 60 sec three times daily with a handheld device during 3 weeks. We related the result to subsequent occurrence of AF as detected in 12-lead ECG recordings. Methods The patients were identified in the local database of cardiovascular investigations. Their clinical profile and vital status during the follow-up were obtained from the Swedish Stroke Register and the Swedish general population registry. For comparison, we used an age- and sex-matched population with no known cerebrovascular event and a population with a cerebrovascular event that was not screened. Results AF was detected in 7.1% by continuous screening and in 5.1% by intermittent screening (P = 0.3). During follow-up of 32 months, AF in 12-lead ECG was found in 7.0%. In the subgroup with positive screening, 46.3% had AF compared with 6.7% in the subgroup with negative screening (P < 0.0001). Conclusions The two screening approaches had a similar yield of arrhythmia, in spite of the group with intermittent monitoring having a more favorable clinical profile. A positive screening was highly predictive of AF in ECG during the follow-up.
Designing an Optimal Two-Bin Strategy for Selling Perishable Produce to Responsible and Mainstream Buyers

Upstream produce vendors in supply chains are paying attention to the possibility of supplying goods to downstream buyers that strive to source responsibly. We explore a problem—the application of a two-bin strategy by vendors to sell produce to responsible buyers (RBs) and mainstream buyers (MBs). In this strategy, goods in the primary bin are supplied to an RB, which procures stable quantities of goods and provides fair procurement prices; goods in the secondary bin are supplied to MBs, which are price sensitive. We investigate a vendor's joint decisions regarding the primary bin replenishment quantity and selling price of goods in the secondary bin for short shelf life and long shelf life produce. For short shelf life produce, we formulate stylized newsvendorlike models and identify the vendor's optimal joint replenishment–price decisions, which are irrelevant to any surplus. For long shelf life produce, we formulate periodic-review dynamic programming models and characterize the solution structure of joint decisions, which depend on the surplus quantity in the secondary bin; the joint decisions are reduced by an increase in the surplus, and when surpluses become sufficiently large, the primary bin replenishment quantity is fixed. We numerically discover that the optimized primary bin replenishment quantity leads to an average profit improvement of 1.5% and that the optimized selling price in the secondary bin results in another 0.25% gain. Furthermore, relative to the sales of produce to only MBs, the supply of goods to an RB can at least double a vendor's profits.
Value of Multislice Spiral CT in Differential Diagnosis of Thick-Wall Gallbladder Carcinoma and Chronic Cholecystitis

To summarize the value of multislice spiral CT (MSCT) in the differential diagnosis of thick-wall gallbladder carcinoma (TWGC) and chronic cholecystitis (CC), the clinical data of 36 patients with TWGC and 60 patients with chronic cholecystitis who were treated in our hospital from January 2017 to May 2021 were retrospectively analyzed, and the CT image features and diagnostic accuracy of the patients were summarized. Compared with the CC group, the proportions of disruption of gallbladder mucosa line, blurred gallbladder outline, high obstruction of biliary tract, lymphomegaly, adjacent invasion, peritoneal effusion, wall nodules, and the gallbladder wall thickness in the TWGC group were higher, with statistical significance (P < 0.05). Thirty-four patients with TWGC and 62 patients with chronic cholecystitis were diagnosed by MSCT. The sensitivity and specificity of MSCT in diagnosing TWGC were 86.11% and 95.00%, respectively. The positive likelihood ratio was 17.222 and the negative likelihood ratio was 0.1462. The positive prediction rate was 91.18%, the negative prediction rate was 91.94%, and the correct rate was 91.67%. MSCT can show the characteristic difference between TWGC and chronic cholecystitis, which can be used for differential diagnosis.
Queue-Aware Finite-Blocklength Coding for Ultra-Reliable and Low-Latency Communications: A Cross-Layer Approach

To provide reliable transmissions with low-latency requirements, we focus on Finite-Blocklength Coding (FBC) in Ultra-Reliable and Low-Latency Communications (URLLC). However, ensuring the reliability and latency of FBC has remained an open issue in URLLC. In this paper, we develop a queue-aware FBC scheme under random arrivals. With the awareness of queue length, we employ variable-length coding to jointly encode packets, through which we obtain a benefit on reliability. Meanwhile, we optimize latency under a cross-layer approach, in which two classes of variable-length codes are investigated with resources allocated in the frequency and time domains, respectively. To obtain an optimal reliability-latency tradeoff under variable-length FBC, we first present the reliability and latency performance for single links based on a Constrained Markov Decision Process (CMDP). Providing reliability with a power allocation, we then obtain the optimal tradeoff by a Linear Programming (LP) problem, in which the probability of violation of the constraints on queue length and the number of transmitted packets is minimized under average constraints on resources. Moreover, we show an optimal threshold-based policy under Bernoulli arrivals. We finally consider some extensions of the optimal tradeoff for multi-user downlinks as well as single links with retransmission.
