With the accelerated pace of urbanization and the increasing number of power users in urban areas, increased the amount of business of urban power communication system. At the same time, the distribution of users in remote areas, such as rural areas has been reduced, which means that the business needs of power communications reduced. For the situation, We proposed a power system communication architecture based on the number of terminal equipment. The scheme will effectively improve the current situation of electric power communication terminal access network, and improve the efficiency of information transmission.

Background Posting of doctors in remote rural areas has always been a priority for Government; however data are scarce in the country about experience of doctors of working in remote areas after medical graduation.Objective A questionnaire survey of doctors was planned to analyze their experience of working after graduation in remote rural areas in various parts of the country.Method The cross-sectional survey was done by convenience sampling method. A one-page questionnaire with one partially closed-end and five open-end type questions was distributed to the doctors who had worked in remote rural areas after graduation under various governments’ postings.Result Two-third of participants had their home in urban areas and 89.8% had stayed for 1 to 5 years. About half of the participants had difficulty in getting the posting in the remote areas of their choice. Most participants indicated provision of opportunities for Residential (postgraduate) Training as their reasons of going to remote areas as well as their suggestions to encourage young graduates to go there. Similarly most also suggested appropriate career, salary and incentives to encourage doctors to go to work in remote areas. About 85% of participants pointed out the major problem faced while posted in remote areas as difficulty in handling varied situations with no guidance or seniors available around.Conclusion The notable points indicated by the participants are centered on the opportunity for Residential Training and difficulties faced without such training. Residential Training is a priority to be considered while planning the health policy for optimum health care of people.Kathmandu University Medical Journal Vol.12(2) 2014: 121-125

Education is a fundamental right of all children, including those with special educational needs. Efforts to achieve education for all has resulted in the focused attention of governments around the world, thereby improving the quality of education in schools and leading to dignified social status for students previously marginalized and/or denied admission to schools. This worldwide movement following various international conventions and mandates has resulted in local efforts to reach rural remote areas, with education provided by the government in most countries. Though there has been significant progress in reaching children, it has not been uniform. There are still many barriers for children in rural and tribal areas or in remote parts of the country that prevent them from receiving equitable education. The essence of inclusive education is to build the capacity to reach out to all children, thereby promoting equity. In the 1990s, special needs education was a focus, and integrating it into the overall educational system led to reforms in mainstream schools which resulted in inclusive education that addressed the diverse learning needs of children. How successful have we been in these efforts particularly in the remote and rural areas? There are various models and practices for special and inclusive education in rural and remote areas, but reaching children with special educational needs in such areas is still a challenge. Though there are schools in these areas, not all are sufficiently equipped to address the education of children with special needs. Furthermore, teachers working in rural areas in many countries are not adequately trained to teach those with special needs, nor are there the technological support systems that we find available in urban areas. Yet, interestingly, in some rural/tribal communities, the teachers are naturally at ease with children with diverse needs. The schools in such areas tend to have heterogeneous classes with one teacher providing instruction to combined groups at different grade levels. Evidence shows that rural teachers are less resistant to including children with special needs compared to urban teachers. Because of their homogeneous lifestyle, community supports in rural areas offer another supportive factor toward smooth inclusion. Though primary education is ensured in most rural and remote areas, children have to travel long distances to semi-urban/urban areas for secondary and higher education; such travel is further complicated when the child has a disability. In many rural areas, children with special needs tend to learn the traditional job skills naturally associated with that area, though such skills are not always blended into the school curriculum. Preparing teachers to provide education in rural areas with the latest technological developments and a focus on vocation is bound to make that education more meaningful and naturally inclusive.

Because of low potential revenue, network operators have mainly focused on providing connectivity in urban areas rather than in rural areas resulting in technology improvement in favour of urban areas; and consequently, most of remote areas suffer from poor or lack of connectivity. In this paper, we present the potential of massive-MIMO to provide connectivity to sparse areas. We show that we can cover large rural areas with radius of tens of km using massive-MIMO mounted on existing infrastructure of TV towers. We also show that, in contrast with common belief, higher frequencies, e.g., 3500 MHz rather than 700 MHz, can reach farther utilizing massive-MIMO, provided that the antenna area is the same.

Mobile networks are experiencing a great development in urban areas worldwide, and developing countries are not an exception. However, sparsely populated rural areas in developing regions usually do not have any access to terrestrial communications networks because operators cannot ensure enough revenues to justify the required investments. Therefore, alternative low-cost solutions are needed for both the access network and the backhaul network. In this sense, in order to provide rural 3G coverage in small villages, state-of-the-art approaches propose to use Small Cells in access networks and inexpensive multihop wireless networks based on WiFi for long distances (WiLD) or WiMAX for backhauling them. These technologies provide most of the required capabilities; however, there is no complete knowledge about the performance of WiFi and WiMAX in long-distance links under quality of service constraints. The aim of this work is to provide a detailed overview of the different alternatives for building rural wireless backhaul networks. We compare both IEEE 802.11n and IEEE 802.16 distance-aware analytical models and validate them by extensive simulations and field experiments. Also WiFi-based TDMA proprietary solutions are evaluated experimentally and compared. Finally, results are used to model a real study case in the Peruvian Amazon in order to illustrate that the performance provided by these technologies may be sufficient for the backhaul network of a rural 3G access network based on Small Cells.

Abstract Background Knowledge of geospatial pattern in comorbidities prevalence is critical to an understanding of the local health needs among people with osteoarthritis (OA). It provides valuable information for targeting optimal OA treatment and management at the local level. However, there is, at present, limited evidence about the geospatial pattern of comorbidity prevalence in Alberta, Canada. Methods Five administrative health datasets were linked to identify OA cases and comorbidities using validated case definitions. We explored the geospatial pattern in comorbidity prevalence at two standard geographic areas levels defined by the Alberta Health Services: descriptive analysis at rural-urban continuum level; spatial analysis (global Moran’s I, hot spot analysis, cluster and outlier analysis) at the local geographic area (LGA) level. We compared area-level indicators in comorbidities hotspots to those in the rest of Alberta (non-hotspots). Results Among 359,638 OA cases in 2013, approximately 60% of people resided in Metro and Urban areas, compared to 2% in Rural Remote areas. All comorbidity groups exhibited statistically significant spatial autocorrelation (hypertension: Moran’s I index 0.24, z score 4.61). Comorbidity hotspots, except depression, were located primarily in Rural and Rural Remote areas. Depression was more prevalent in Metro (Edmonton-Abbottsfield: 194 cases per 1000 population, 95%CI 192–195) and Urban LGAs (Lethbridge-North: 169, 95%CI 168–171) compared to Rural areas (Fox Creek: 65, 95%CI 63–68). Comorbidities hotspots included a higher percentage of First Nations or Inuit people. People with OA living in hotspots had lower socioeconomic status and less access to care compared to non-hotspots. Conclusions The findings highlight notable rural-urban disparities in comorbidities prevalence among people with OA in Alberta, Canada. Our study provides valuable evidence for policy and decision makers to design programs that ensure patients with OA receive optimal health management tailored to their local needs and a reduction in current OA health disparities.

Access to broadband telecommunication infrastructure is important for both urban and rural areas. In urban areas market forces ensures access to service providers. In many rural and remote areas this is not the case. Local actors need to initiate the development of the infrastructure. This paper contributes to the development of a staged model for infrastructure development. We explore how local stakeholders have initiated and sustained the development of broadband access in rural and remote areas of Norway. Our conclusion is that the model is relevant in a Norwegian context. However we see the need to extend and strengthen it with elements of local reflexive processes taking context, feedback, learning, and global change forces into account. In initiating a timely development to meet local needs it is important to have a staged reflexive approach.  Such a model provides a path of development that allows local and regional initiatives to aggregate and grow.

Population is concentrated in the major cities which are facing the energy deficiency issues. The unregulated development of micro-urban areas is underestimated in both cases (Slovak Republic and Taiwan R.O.C.) so are the energy issues bound with them. Centralized energy sources require long distance wires to support remote areas.

AbstractUrbanization processes are increasing globally. Anthropogenic alterations in the environment have profound effects on biodiversity. Decreased biodiversity due to biotic homogenization processes as a consequence of urbanization often result in increased levels of mosquito vector species and vector-borne pathogen transmission. Understanding how anthropogenic alterations in the environment will affect the abundance, richness, and composition of vector mosquito species is crucial for the implementation of effective and targeted mosquito control strategies. We hypothesized that anthropogenic alterations in the environment are responsible for increasing the abundance of mosquito species that are adapted to urban environments such as Aedesaegypti and Culexquinquefasciatus. Therefore, our objective was to survey mosquito relative abundance, richness, and community composition in Miami-Dade County, Florida, in areas with different levels of urbanization. We selected 24 areas, 16 remote areas comprised of natural and rural areas, and 8 urban areas comprised of residential and touristic areas in Miami-Dade County, Florida. Mosquitoes were collected weekly in each area for 24 h for 5 consecutive weeks from August to October 2020 using BG-Sentinel traps baited with dry ice. A total of 36,645 mosquitoes were collected, from which 34,048 were collected in the remote areas and 2,597 in the urban areas. Our results show a clear and well-defined pattern of abundance, richness, and community composition according to anthropogenic modifications in land use and land cover. The more urbanized a given area the fewer species were found and those were primary vectors of arboviruses, Ae.aegypti and Cx.quinquefasciatus.

The lack of access to quality healthcare and the lack of sufficient manpower, especially doctors, in rural areas is a major healthcare challenge faced by dwellers in rural communities in most developing countries. The intervention of governments, which range from the introduction of training programs aimed at producing health workers from schools of health technology and nursing to the recalling and deployment of retired nurses to rural areas, has still not been able to generate the desired improvement in healthcare delivery, as outbreaks of epidemics are still being reported in such areas. This work presents an E-Health architecture which utilizes low cost sensors and communication devices to link the doctors in the urban areas with the patients in rural areas enabling doctors-patients interaction. The system enables accurate and timely diagnosis of the patients and facilitates proper treatment plans. It also incorporates an epidemic alert which enables the tracking of diseases and the early detection and control of epidemics.
