Computer-assisted telephone interviews (CATI) through mobile phones are a low-cost, rapid and safe way to collect data. However, decisions for how such mobile phone surveys are designed and implemented, and their data analysed, can have implications for the sample reached, and in turn affect the generalisability of sample estimates. In this practice paper, we propose a framework for extending the use of CATI–mobile phone surveys in India, which can be applied broadly to future surveys conducted using this method. Across the stages of design, implementation and analysis, we outline challenges in ensuring that the data collected through such surveys are representative and provide recommendations for reducing non-coverage and non-response errors, thereby enabling practitioners in India to use CATI–mobile phone surveys to estimate population statistics with lower bias. We support our analysis by drawing on primary data that we collected in five mobile phone surveys across nine Indian states in 2020. Our recommendations can help practitioners in India improve the representativeness of data collected through mobile phone surveys and generate more accurate estimates.

<p class="p1"><span class="s1">Considering the deficiency that the existing automobile accident self-rescue system requires to assemble the specific sensor, GPS and communication module, the author designed a vehicle collision or  crash detection and accident self-rescue system based on the smart mobile phone groups. Taking the acceleration signals of physical moments from the smart mobile phones in the accidents car as the input samples and the assembly of acceleration data as the calculating thresholds, the system can not only improve the accuracy rating of the judgments about the accidents, but can also reduce the unusable distress signals due to the damages to individual vehicle-borne device or mobile phone in severe accidents. When the signals exceed the threshold value, the system can draw support from the functions of video, GPS positioning and 3G networking in the mobile phones automatically to call for help from the rescue center. Meanwhile, a prototype system has been implemented on Android platform. The results of the experiments indicate that the system possesses the advantages of high accuracy of collision or crash recognition, low energy consumption and low cost.</span></p>

Belajar kosakata adalah langkah awal untuk belajar bahasa asing Namun, hasil belajar bahasa Inggris siswa di Indonesia masih dibawah rata-rata. Hal ini mungkin disebabkan oleh keterbatasan kosakata siswa yang mempengaruhi kemampuan mendengar, berbicara, menulis dan membaca. Studi ini bertujuan untuk melihat apakah penggunaan handphone dan flashcards dapat meningkatkan pemerolehan kosakata siswa dan juga untuk melihat persepsi siswa kelas X terhadap penggunaan handphone dalam belajar kosakata. Penelitian ini menggunakan nonrandomized kontrol group pretest dan posttest. Sampel penelitian ini adalah siswa kelas X SMA Negeri 4 Lahat. Data dalam penelitian ini diperoleh dengan menggunakan test dan angket. Data yang diperoleh dianalisa dengan menggunakan one-way ANOVA. Hasil penelitian ini menunjukkan bahwa ada peningkatan yang signifikan dalam pemerolehan kosakata siswa dengan menggunakan handphone dan flashcards setelah diberikan perlakuan. Pemerolehan kosakata siswa dengan menggunakan handphone lebih tinggi dibandingkan dengan siswa yang menggunakan flashcards. Dari studi ini diketahui juga bahwa siswa kelas X SMA Negeri 4 Lahat memiliki persepsi positif terhadap pembelajaran kosakata dengan menggunakan handphone.Learning vocabulary is the fundamental step to learn a foreign language. Vocabulary gives contribution to the learners to perform or practice their skills better. However, Indonesian students’ English score is still below average. It may be caused by their limited vocabulary which influence their listening comprehension, speaking, writing and reading abilities. Therefore, the objectives of this study were to see whether the use of mobile phone and flashcard could improve students vocabulary achievement and also to see the perceptions of the tenth grade students of learning vocabulary via mobile phone. The nonrandomized control group pretest-posttest design was applied in this study. The sample of the study was 90 first year students of Sekolah Menengah Atas Negeri 4 Lahat. The primary data were obtained by means of the tests and questionnaire. The obtained data were analyzed using one-way ANOVA. The results of the study showed that there was significant progress in the vocabulary achievement of the students using vocabulary learning program in mobile phones and flashcards after the treatment. The vocabulary achievement of the students using vocabulary learning program in mobile phone was higher than using flashcards. From this study it was also found that the tenth grade students had positive perception of learning vocabulary via mobile phones.

The access to agricultural information in Sudan continues to be challenging to farmers due to use of inadequate sources and traditional extension approaches. The rapid growth of smart-mobile phones usage in developing countries resulted in several advantages compared to other alternatives in term of costs, geographic coverage and ease of use. This research was conducted in North Kordofan Sate to explore the role of smart-mobile phone in accessing agricultural information. Primary data were obtained by structured questionnaires and focus group discussion through participatory rural appraisal and observation while secondary data were collected from scientific journals, books and authenticated web sources. A number of 230 respondents (10% from total farmers) were interviewed and five focus group discussions were done. Statistical Packages for Social Science (SPSS) version 22 was used to analyze the data with aid of descriptive statistics and Chi-squire Test. The result indicated that most of the respondents fall in age group between 21-40 years, and they depend on farm activity. There was 90% of farmers processed mobile phone since more than three years ago, 90.8%continuedto use smart mobile phone to access agricultural information and showed positive contribution towards income generation. The results also revealed that there was positive perception towards using mobile phones which showed more efficient in use than radio and TVs. The results showed great advantages of using smart mobile phone where 75.2 % of respondents preferred to get agricultural information, logistics and other needs through successful communication in the mid of agricultural season. Results of Chi-squire test showed significant differences between the parameters tested. The study recommended that farmers should be connected with mobile phones to admit ease communication with agricultural extension offices and quick access to their needs and logistics.

In this chapter, a method is proposed to contact the Police with mobile phones and via SMS (Short Message Service). In this method, when a person wants to contact the Police, he must only press a special key on his mobile phone for a short time to launch a special program. This program sends current location of the person using GPS system and sends it periodically with other useful information such as name, home and work address of that person automatically to the Police Station using SMS. In this method, there is no need to talk and a person can contact the Police easily and tell them the place which crime has occurred. In addition, there is no busy line problem. This method has low cost and can be run on many mobile phones This method is implemented using JavaME (Java Platform Micro Edition) programming language and tested on a Nokia N71 mobile phone by using an ‘Evermore BT-R700’ GPS receiver.

Background:There are reported concerns of patient misunderstanding of the COVID-19 pandemic and vaccination safety. It is particularly important that these are understood in patients taking complex immunusuppressive therapies. Rapid delivery of targeted and up-to-date video messages from clinicians sent directly to patients could address patient uncertainty, and improve COVID-19 vaccination uptake. Innovative SMS (short message service) based video message has already shown promise in delivering COVID-19 information to patients [1]. We present our experience in creating a tailored vaccine information video sent directly to our large cohort of patients in the UK with a range of rheumatic diseases and report on the learning points going forward.Objectives:Our three objectives were: (1) educate our patients using an interactive mobile video information resource outlining the safety of the COVID vaccination in these patient groups; (2) better understand our patients’ views of the COVID-19 vaccine; (3) evaluate the patient experience of this approach.Methods:We designed and recorded an 8-minute interactive web-based video delivered education resource designed for mobile phones. This included: aims of the video; details of licenced vaccines; UK vaccination schedule; frequently asked questions; links to national charity resources; our clinician recommendations; a rheumatologist being vaccinated; case studies; and summary data. We produced a simple mobile phone web-based evaluation of the resource, including anonymised patient demographics, their understanding of the safety of the vaccine pre/ post video, and their user experience. Resource and evaluation were piloted by local healthcare professionals, our Patient Participation Group, a national charity, and approved by senior management. We distributed this to our follow-up patient cohort via our hospital SMS provider on 21.12.20, at the start of roll-out of UK vaccines, containing a link to the resource and evaluation.Results:Of a cohort of 10,981 patients, we had 8886 mobile phone numbers. At Day 14, we recorded 2358 video views (26.3%) and 664/2358 completed evaluations (28.1%). Only one person reported being unable to watch the video. Before watching the video, 348/664 patients (52.4%) were unsure if the vaccine was safe and/or recommended for them, rising to 626/664 (94.3%) post-video.Reasons for uncertainty after the video (38/664) included drug allergy and fertility concerns. Following the video, 509/664 patients (76.6%) reported that they were more likely to have the vaccination. The majority of the patients (614/660, 93.0%) agreed that the method was a helpful method to share such information.Age distribution of our whole cohort, patients with mobile phones, and responders were similar: Age >50 was 80.4%,76.3%,and 88.6% respectively. A large proportion was treated with immunosuppressive medication (61.3% conventional DMARD, 39.4% biological DMARD and 17.6% corticosteroids). Gender and case mix for responders were similar to published data from our cohort: female 74.0%; rheumatoid arthritis commonest disease (389/664, 58.5%).Conclusion:To our knowledge, this is the first study to show the potential for SMS linked interactive multimedia message for patient education. The multimedia component allows users to easily navigate to relevant sections, and access a choice of linked resources. We demonstrate this low-cost technology is simple, effective and well placed to assist physicians in educating patients during a time when face-to-face contact is proving to be difficult. We have shown high levels of patient satisfaction, reassurance, and self-reported behaviour change. Such technology has potential utility for national bodies, primary and secondary care groups, and merits further research.References:[1]The Lancet Rheumatology.

<div><p><em><span>Opening of new branch in every village is uneconomical for any traditional bank. Transactions through mobile phones may cover a low cost platform for basic banking services to every rural or urban citizen. India’s domestic remittance market is more than Rs. 900 Billions. The payment banks play a vital role in implementing the government’s direct benefit transfer scheme, where subsidies on healthcare, education and gas are paid directly to beneficiaries’ accounts. Keeping in mind the government's unwavered digital drive target, customers shifting from cash transactions to operating their accounts on their mobile phone, this paper discusses the objectives of primary banks, its history and services rendered by it. This paper also focuses on m-Banking, the Department of Posts, Pradhan Mantri Jan-Dhan Yojana and the India Post Payments Banks.</span></em></p></div>

Repair of mobile phones fits with the vision of a circular economy in an urban context and with the Sustainable Development Goal 11 Sustainable Cities and Communities. Drawing on the literature about firm level competitiveness and closed-loop design through repair, remanufacturing or recycling, we analyze the business ecosystem of independent mobile phone repair shops in the Netherlands, Poland and China as a glocal business activity. The analysis is based on primary data collection through a questionnaire to independent repair shops in the Netherlands (n = 130), Poland (n = 443) and China (n = 175) with response rates of 13%, 12%, 40%, respectively; and 17 interviews in the Netherlands, 40 in Poland, and 70 in China. Findings indicate that to maintain a strong position in the local market and to sustain the trust of customers, independent mobile phone repair shops offer a range of customized services based on direct contact with customers. In China, the increasing prices of spare parts and falling prices of mobile phones constitute the most important challenges, whereas in the Netherlands and Poland, the most important challenges are the competitive pressures from informal repair activities, and new repair shops. Our research also revealed that repairability strongly depends on the global manufacturers’ circularity choices.
