Germonpré P, Van der Eecken P, Van Renterghem E, Germonpré F-L, Balestra C. First impressions: Use of the Azoth Systems O’Dive subclavian bubble monitor on a liveaboard dive vessel. Diving and Hyperbaric Medicine. 2020 December 20;50(4):405–412. doi: 10.28920/dhm50.4.405-412. PMID: 33325023.) Introduction: The Azoth Systems O’Dive bubble monitor is marketed at recreational and professional divers as a tool to improve personal diving decompression safety. We report the use of this tool during a 12-day dive trip aboard a liveaboard vessel. Methods: Six divers were consistently monitored according to the user manual of the O’Dive system. Data were synchronised with the Azoth server whenever possible (depending on cell phone data signal). Information regarding ease of use, diver acceptance and influence on dive behaviour were recorded. Results: In total, 157 dives were completely monitored over 11 diving days. Formal evaluations were only available after six days because of internet connection problems. Sixty-one dives resulted in the detection of bubbles, mostly in one diver, none of which produced any symptoms of decompression illness. Conclusions: The O’Dive system may contribute to increasing dive safety by making divers immediately aware of the potential consequences of certain types of diving behaviour. It was noted that bubble monitoring either reinforced divers in their safe diving habits or incited them to modify their dive planning. Whether this is a lasting effect is not known.

Rapid advances in mobile data-transfer technologies offer new possibilities in the use of cell phones to conduct assessments of a person’s natural environment in real time. This paper describes features of a new Internet-based, cell phone-optimized assessment technique (ICAT), which consists of a retrospective baseline assessment combined with text messages sent to the participants’ personal cell phones providing a hyperlink to an Internet-stored cell phone-optimized questionnaire. Two participation conditions were used to test variations in response burden. Retention rates, completion rates, and response times in different subgroups were tested by means of χ² tests, Cox regression, and logistic regression. Among the 237 initial participants, we observed a retention rate of 90.3% from the baseline assessment to the cell-phone part, and 80.4% repeated participation in the 30 daily assessments. Each day, 40–70% of the questionnaires were returned, a fourth in less than 3 minutes. Qualitative interviews underscored the ease of use of ICAT. This technique appears to be an innovative, convenient, and cost-effective way of collecting data on situational characteristics while minimizing recall bias. Because of its flexibility, ICAT can be applied in various disciplines, whether as part of small pilot studies or large-scale, crosscultural, and multisite research projects.

Broadband over powerline (BPL) is a technology that allows connectivity to internet connection riding via the low tension (LT) power line communication (PLC). A hybrid BPL technology was proposed to the rural area of Sarawak as an alternative option to expand the internet connection without the need to reform a new pathway for internet connectivity. The data signal is transmitted via a communication tower to the access point(s) that is mounted on an electricity pole that provides a low voltage (LV) line. There are three types of custom-designed equipment that has been integrated into the hybrid BPL: the Head End (HE), the Time Division Repeater (TDR) and the Customer Premise Equipment (CPE). Two longhouses at the Bawang Assan, Sarawak settlement has been chosen to initiate the pilot project that required the cooperation of the technology provider, power producer, and the internet service provider. This paper presents a proof of concept (POC) on the deployment, advantages, and limitations for the BPL in a rural setting.

Background The process of triaging is performed as an effective solution to balance limited resources against high patient volumes, based on an assessment of the patient’s medical condition and the application of an established patient categorization protocol. In Princess Marina Hospital (PMH), a national referral government hospital in the capital city of Botswana, the Princess Marina Hospital Accident and Emergency Centre Triage Scale (PATS) has been in use since 2010. Because the rules of these triage scales are very well defined, these protocols have been shown to be amenable to translation into computer algorithms. Thus, clinical decision support systems (CDSSs) that can assist with information management to support clinicians’ decision-making abilities can be developed, leading to improved healthcare quality and patient safety. Objective This study aims to determine the feasibility of development of a mobile triage app based on the adult PATS using Open Data kit (ODK) open source software to be used as a CDSS on smartphones and tablet computers for correct patient categorization. Methods A user-centered design approach was used in designing the app, with participants recruited from the staff at the Accident and Emergency Department (A&E) at PMH. Forty clinical vignettes were used in the evaluation of the performance of the app as compared to the paper-based system currently in use with the emergency physician at PMH providing the gold standard categorization of these vignettes. Usability testing was also performed. Results The app scored 90% (n=36) of the vignettes correctly, as compared to the paper-based system which scored 82.5% (n=33) of the vignettes correctly. Both systems achieved an over-triage score of 7.5% with an equal number of vignettes over-triaged (n=3). The results of the chi-square test indicate that the difference in triage scores between the paper-based system and the mobile app is statistically significant at P=.001 in favour of the ODK app. An overall positive outcome was also achieved in the usability test with ease of use and speed of triage determined to be the most recurring themes in the user feedback survey. While the app does not require an internet connection for triaging patients, a reliable wireless internet connection is required to upload data to the server for viewing by medical officers and physicians in real time, and this can be provided by the hospital as part of the Botswana government eHealth strategy. Additionally, the app developed in this research allows for data collection up to the point of triage categorization, meaning that a separate form would be required for capturing the rest of the information on the PMH A&E triage form. Conclusions The triage app developed in this research was found to determine the triage category of patient vignettes more accurately than the traditional paper-based system based on PATS triage guidelines with good results obtained in usability testing. Future work includes use of the app developed in this research in a live setting involving real patients in the A&E in PMH.

The authors present a Student Response System for modern Internet-capable mobile devices, which was developed in a European R&D project, co-funded by the European Commission. The goal was to make a system that is designed for speed, ease of use, and flexibility for use in lectures. The authors have tried to make a time efficient and intuitive system that does not compromise flexibility and that enables the teacher to use any lecture format he/she sees fit. The only requirement is a computer with an Internet connection; the teacher is not bound to specific presentation software. The system is Web-based, enabling students to use their own mobile device or computer. The cost for both educational institutions and students is kept at a minimum, lowering the threshold for using the system in education. As of today, the program is free of charge and can be found at histproject.no.

Computer assisted language learning (CALL) is one of the alternative ways used by teachers in teaching English. This research aims to find out various CALL applications used by the pre-service English teachers, the difficult skills faced by students, hindrances, and pre-service teachers’ reflection. A mixed-method approach with questionnaires, interviews guideline, and observation checklist were employed by the researchers. The sample consisted of 30 pre-service English teachers and 750 students. The data analyses were done by using simple statistics calculations, codes, and categories. The results showed that pre-service English teachers applied various CALL applications, in which the majority of them used Hello English for speaking in the classroom because of the ease of use of the application. The most difficult skills learned by students were listening, and the easiest skill was reading. Another finding is related to hindrances during CALL applications which included internet connection, material understanding, CALL application procedures, assessment, discipline, cost, and learning style. However, those problems were eventually solved by pre-service English teachers. Furthermore, pre-service teachers wrote their teaching reflection to know their evaluation of their teaching. The reflections showed that they could solve the problems, made, and revised lesson plans, and brought good role models in the classroom.

In supplying the dragon fruit market, dragon fruit farmers use irradiation methods in the off-season to increase the productivity of dragon fruit harvests, with manual dragon irradiation methods seen as less effective in the process of irradiating the operation, the role of technology can be used in the irradiation control system of dragon fruit gardens. based on the internet of things in order to be effective in operating the irradiation of dragon fruit garden lights in a long distance and produce maximum out of season harvest. The study was conducted in 4 stages: needs survey, design, prototype, trial. In the trial using the ESP 8266 wifi module, the module has the disadvantage that it is easy to heat when searching for a wifi signal that is used in the process of transmitting light control system data which is assumed to be the irradiation of the dragon fruit garden, so that it can cause problems in the internet connection. But in the results of testing the IoT-based control system which is assumed to irradiate the dragon fruit kebuh in 4 well-controlled lights with 100% success. In this research it is recommended to use the ESP 8266 wifi mode with good internet facilities because ESP 8266 can work optimally by an internet connection. If the internet connection used is unstable, it will make the ESP 8266 module become hot so it can make the module burn

(Thaler J, Pignel R, Magnan M-A, Pellegrini M, Louge P. Decompression illness treated at the Geneva hyperbaric facility 2010–2016: A retrospective analysis of local cases. Diving and Hyperbaric Medicine. 2020 December 20;50(4):370–376. doi: 10.28920/dhm50.4.370-376. PMID: 33325018.) Introduction: The Geneva hyperbaric chamber is the main treatment centre for decompression illness (DCI) in Switzerland. The characteristics, symptomatology, treatment and short-term outcome of divers treated at this chamber have not previously been investigated. Methods: This was a retrospective study of patients treated with hyperbaric oxygen (HBO) for DCI from 2010 to 2016. Data were analysed to provide a description of the cases and statistical analysis for possible factors associated with an unfavourable outcome. Results: One hundred and thirty-five patients were treated for DCI. Ninety-two were included in the study. Sixty-four presented with neurological and 28 with mild DCI. One hundred and thirty-five patients were treated for DCI. Ninety-two were included in the study. Sixty-four presented with neurological and 28 with mild DCI. Patients with mild DCI mainly had musculoskeletal symptoms (79%). Patients with neurological DCI mainly had spinal (55%), followed by vestibular (36%) symptoms. Arterial gas embolism was diagnosed in 30% of cases. Diving depths ranged between 15 and 142 metres, and dive times between two and 241 min. Median time to treatment was 6 h. Patients with neurological DCI had a high rate (25%) of persisting deficits after treatment. Older age was associated with an unfavourable outcome in univariate but not in multivariate analysis. No adverse effects of HBO were observed. For spinal DCI, a high Boussuges score was associated with persisting deficits after treatment. Conclusions: Our findings are consistent with other series. Severe DCI was associated with a high rate of persisting deficits. No single factor was associated with a negative outcome. A Boussuges score > 7 had sensitivity of 90% and positive predictive value 53% for predicting an unfavourable outcome in spinal DCI.
