<span>It is generally considered that remote and rural telephone users generate less traffic as compared<span> to urban area users. This lowers the attraction of investment in rural areas by the<span> telecommunications companies and service providers. The financial implications of wiring a<span> vast area for low telephone traffic causes most telephone service providers to ignore those<span> regions. Still, it is known that telecommunications are essential to the economic development of<span> a region and that traffic increases rapidly as soon as the service is available. A satellite–based<span> telephone network can provide efficient long distance telephone service to remote rural<span> communities at a lower cost than land-based wired networks in most cases. Mobile satellite<span> systems already provide this service, but are limited in capacity and charge high per-minute fees<span> for the satellite link. Small earth stations and GEO satellites can provide this service more<span> efficiently and at lower cost. On top of that, bandwidth efficient multiplexing with compressed<span> speech, Voice Activity Detection (VAD) and Packet discarding methods can even further reduce <span>the cost of service for the users in rural areas. In this paper, Statistical Time Division Multiplexer<span> (STDM) architecture was simulated. Two packet discarding methods, random packet discarding<span> and cyclic packet discarding are used to maximize bandwidth utilization along with VAD.<span> Results indicate that considering monologue speech source, with 80%, activity for each 6.4 kbps<span> sources, on a channel of 64 kbps, 12 users can be allowed to be multiplexed instead of 9,<span> therefore a Digital Speech Interpolation (DSI) advantage of 1.33 is achieved with 3% packet<span> loss. Furthermore, it is observed that cyclic packet discarding technique perform better than<span> random packet discarding in terms of subjective quality<br /><br class="Apple-interchange-newline" /></span></span></span></span></span></span></span></span><br /><br class="Apple-interchange-newline" /></span></span></span></span></span></span></span></span></span></span></span></span>

Routine transmission of electrocardiograms and their computer interpretation via long-distance telephone lines has been proven feasible in the Automated Electrocardiogram Project of the Missouri Regional Medical Program. Though this Pilot Project — the first on a state-wide basis — is still viewed as an applied research effort rather than a service, such biotelemetry is rapidly gaining acceptance as a medium to bring modern medicine, through modern technology, to urban and remote rural areas as well, where it is most needed.The computer executes all the wave measuraments and calculations with incredible speed. It takes over a most boring, repetitive part of the physician’s work. However, it can only follow the instructions of the diagnostic program, compiled by expert cardiologists. Thus, it is an ever-ready, never-tiring servant for the physician and his patients.

The Silk Road

Chinese government has developed transport infrastructure rapidly under Belt and Road Initiative (BRI) strategy. The BRI strategy is China's economic development strategies for expanding trade and cultural influence towards countries in western and eastern regions, including ASEAN. The development of BRI strategy is consists of two main components i.e., (i) the Silk Road Economic Belt, follows the historical overland Silk Road through Central Asia, Iran, Turkey and eventually to Europe, and (ii) the Maritime Silk Road, originates in the South China Sea, passing through the Malacca Strait, the Indian Ocean, and the Red Sea and extending into the Mediterranean Sea (Chris & Elizabeth, 2015). Due to the BRI strategy, more than 6000 trains made the journey from China to Europe in 2018, which is an increase of 72% compared to 2017. China has sent more than 11,000 freight trains to Europe and back since the BRI strategy was announced in 2013. Railway networks have been constructed under the BRI strategy for connecting 48 Chinese cities with 42 cities in Europe through Asia. There are many railway infrastructures under the BRI strategy. The China – Laos railway (Vientiane–Boten railway) is one of project under the Silk Road Economic Belt that has been developed for serving as a key infrastructure for the economic corridor between the two countries. In nearly future, this railway will be helped to boost trade, investment and tourism for Lao PDR. and south China's Guangxi Zhuang Autonomous Region. The Vientiane–Boten railway, especially transportation time will attract both travelers and Logistics Service Providers (LSP), which can be reduced time of journey compared with road mode. In this paper, modal shift potential of travelers and freight on Kunming-Bangkok Highway (R3A), AH2, AH8, AH9, AH10, AH12, AH13, and AH18 have been investigated by considering behavioral aspects of long distance travel.

Purpose This paper aims to compare the costs of deploying different wireless terrestrial broadband technologies in the Andes and Amazon Regions of Peru. These areas are representatives of different and challenging geographic regions throughout the globe that currently are severely underserved or unserved for vital broadband services necessary to bridge the “Digital Divide”. Design/methodology/approach The broadband technologies studied include Wi-Fi, Worldwide Interoperability for Microwave Access (WiMAX), long term evolution (LTE), TVWS and new stratospheric platforms (super-pressure balloons). This study conducts a technical analysis (design and simulation) of wireless broadband networks, and a bottom-up engineering cost analysis to estimate and compare the deployment and operating costs of the networks over a 10-year period. The analysis also identifies potential regulatory barriers to deployment associated with spectrum allocation licenses and overbooking requirements intended to improve quality of service. Findings Comparison of the capital and operating expenses of these options over a 10-year period finds that LTE and Wi-Fi can be the lowest cost alternatives, though significantly, stratospheric balloons have the lowest initial costs for the first few years and can factor as a low-cost broadband catalyst early in deployment. Finally, the lowest cost technology broadband roadmap for the 10-year period is presented, which includes using stratospheric balloons (carrying micro-LTE base stations) for the first years and deploying complementary terrestrial LTE networks for the rest of the 10-year period. Originality/value This study presents detailed technical and engineering cost analysis results of wireless access network deployments, including advanced wireless technologies and new unmanned aerial systems, to expand broadband services to rural areas in mountainous (Andes Region) and rainforest (Amazon Region) geographies to reduce the digital divide in emerging countries. Results aim to aid governments, regulators, internet service providers (incumbents and competitive) and content providers to assess current alternatives to expand broadband service in these rural areas.

Background: Breastfeeding is an important indicator for child health and mortality. The aim of this study was to determine the level of knowledge and practices regarding EBF and its relation to various socio-economic and demographic factors among mothers with at least one child age (6-12 years) in the rural areas of the Rajshahi district in Bangladesh. Methods: A study based at village hospitals was conducted and a semi-structured questionnaire was used. A total of 513 mothers who had at least one child's age (6-12) months from 32 different village hospitals in rural areas of the Rajshahi District, Bangladesh from September to December 2015. The composite index, chi-square test and binary logistic regression model were used in this study. Results: The incidence of EBF good knowledge and practices was 32.0% and 27.9% among mothers with at least one child age (6-12) months. The analysis shows that the age of mothers ≥ 31 years have less knowledge and practice about EBF compared to mothers aged ≤ 30 years. Mothers who are housewives had a higher probability of good knowledge and practice than mothers who were service providers. Nursing mothers at home have less knowledge and practices about EBF than mothers who gave birth in the hospital. Mothers that had a monthly family income of ≤ 6 699 BDT had less knowledge and practices about EBF compared to mothers with a family income of >6 699 BDT. Conclusions: This study showed a huge gap in EBF knowledge and practices among mothers who have at least one child age (6-12) months. This study suggests that EBF education and interventions can play an important role in increasing EBF good knowledge and practices among mothers with at least one-to-one (6-12) months of age children. Malnutrition will be reduced if the EBF is widely established in Bangladesh.

With modernization and technology enhancements on a global scale, environmental consciousness has also been increasing in recent days. Various technologies and automobile industries are vandalized with sustainable solutions and green technologies. Transportation via roadways is mostly preferred for distant travel as well, despite the advancements in airways and railways, due to less capital outlay, door to door service possibility in rural areas etc. The conventional fuel vehicles are a huge contributor to environmental pollution. Electric vehicles are an optimal solution to this issue. The lives of the common masses are not impacted largely by the electric vehicles despite their market commercialization since a few decades. It is due to certain challenges associated with the electrical vehicles. A 100% efficient perpetual machine does not exist yet. Predominantly, challenges related to charging, hinders the success of e-vehicles. Frequent charging is required in case of long-distance travel and other scenarios in the existing vehicles. Based on the respective governments, extensive changes are made in the infrastructure to overcome the issues at the charging stations. In this paper, an enhanced wireless charging module for electric vehicles is presented. The use of multiple coils is emphasized for building up energy and transmitting it. The inductive power transfer mechanism and efficiency of the system are improved with the design of a three-phase coil. The mechanism for assessment of the energy consumed in e-vehicles is also discussed.

The study aims to answer the question concerning how effectively cities of the Siklós district can involve the surrounding settlements in the tourism economy, thereby promoting the development of rural areas. In addition to local governments and tourism organizations, our important goal is to understand the ideas of service providers and their guests related to rural development, as well as the space use characteristics of the latter group. The key method is the questionnaire survey, the target group of which is the mayors of all settlements in the district, as well as the guests of the accommodations belonging to the different product types. The primary sources are based on two further series of interviews, which explore the opinions of service providers and professional organizations. Empirical experience shows that thematic trips can play a prominent role in the development of the less frequented small settlements. The essence of this is to connect the places offering traditional crafts and local products by a bike route.
