Nowadays, accessibility to facilities is one of the most discussed issues in sustainable urban planning. In the current research, two spatial distance accessibility measures were applied to evaluate the accessibility to amenities, services, and facilities (ASFs) from public transit (PT) by walking distance in six Indian cities. The first stage accounts for distance measures using the Euclidean distance with a new methodical approach derived from the built-up area with a spatial resolution of 30 m from Landsat data, and for the network distance method, the actual road distances using OpenStreetMap (OSM) for different threshold ranges of distances were derived. Meanwhile, in the second stage, indicators such as built-up area, network connectivity, and network density with the percentage of ASFs are evaluated and combined for normalization process for ranking the city. The present study assesses the accessibility to various ASFs from PT at city level and explores whether the actual road network access (by measuring distance) in Indian cities is contributing to a high level of accessibility. It adopts a unique approach using statistical tools while assessing both Euclidean and network distances. It models a framework for overall benchmarking in all six cities by ranking them for their accessibility. The results show various scenarios in terms of the rank of cities, which had been strongly affected by distance metrics (Euclidean vs. network) and thus emphasize the careful use of these measures as supporting tools for planning. This facilitates the identification of the local barriers and problems with network access that affect the actual distance. This unique approach can help policymakers to identify the gaps in PT coverage for reaching ASFs. Furthermore, it helps in crucial implementation by strategic planning that can be achieved using these distance criteria.

Background. This article examines personnel and patient experiences of videoconferencing (VC) trials on tablet computers between oncology certified nurses (OCNs) and patients with cancer who live at home. The study points to organizational pitfalls during the introduction process. In many different arenas, the use of VC has increased recently owing to improved Internet access and capacity. This creates new opportunities for contact between patients living at home and their nurses. Video conferencing presupposes knowledge about Internet access, training, and usability of technological equipment. The aim of this pilot study was to illuminate patients’ and nurses’ experiences of the technical functionality, usability, and training of tablet use in VC in primary cancer care. The results point to the drawbacks concerning the introduction of VC. Method. A pilot study with an explorative design was used to describe patients’ and OCNs’ experiences of technical functionality and usability of VC on tablet computers. After a three-month trial, data were gathered, focusing on both patients’ and nurses’ perspectives. Individual interviews with four female OCNs, aged 32–65 (mean 46), and six patients with cancer, two men and four women aged 49–78 (mean 69), were content-analyzed. Results. The analysis revealed two main categories: network connectivity and tablet usability and training and educational pitfalls. Conclusion. When planning VC implementation, the organizational leadership should consider network access and stability, as well as individualized VC training on tablets. Ensuring patient safety should also be a priority. Further research should provide knowledge of technological and educational pitfalls, and possible implications of VC on the care quality of nursing.

Seiring perkembangan pendidikan, penggunaan ICT sangatlah besar dalam proses perkembangan tersebut. Dengan penggunaan ICT ini, memungkinkan distance learning diimplementasi dimana proses belajar mengajar tidak harus lagi berada dikelas seperti pada pendidikan yang konvensional. Dengan adanya distance learning dapat memecahkan masalah spasial baik dari ukuran ruangan terhadap jumlah murid dan keterbatasan untuk dapat hadir kedalam ruang perkuliahan. Karena itulah, Sistem Pengalokasian Virtual Local Area Network (VLAN) secara Dinamis dibutuhkan. Sistem ini merupakan sistem yang berbasis protokol Radius yang dapat membantu untuk mengotentikasi dan memindahkan client antar sub jaringan (VLAN) didalam jaringan internal suatu perkuliahan.Perancangan sistem digunakan aplikasi berbasis open source. Pada perancangan sistem Dinamik VLAN ini, penulis menggunakan sistem otentikasi berdasarkan MAC-Address dari client yang akan dimapping kedalam VLAN yang akan dituju. MAC-Address dan VLAN yang akan dituju disimpan didalam database. Untuk skema jaringannya, server dan client akan terhubung menggunakan manageable switch.Mekanisme kerja dari sistem pengalokasian VLAN secara dinamis ini terdiri dari 3 (tiga) tahap yaitu: tahap penerimaan request dari Network Access Server (NAS), pengecekan MAC-Address terhadap VLAN yang dituju dan persetujuan otentikasi dan otorisasi. Untuk mendukung proses pembelajaran jarak jauh, digunakan Web Conference dan aplikasi seperti file sharing pada jaringan VLAN tersebut. Untuk pengujian sistem tersebut, kita menggunakan applikasi Web Conference dengan cara membandingkan performa jaringan pada saat dengan dan tanpa sistem tersebut.Dalam mengimplementasikan sistem ini, terbilang murah karena suatu perusahaan hanya membutuhkan sebuah server dengan Sistem Operasi yang gratis dan aplikasi yang gratis dan dapat diimplementasikan langsung ke dalam jaringan perusahaan tanpa perubahan topologi jaringan yang menyeluruh.Namun dalam sistem ini masih terdapat kekurangan, dimana sistem ini hanya dapat diaplikasikan dengan menggunakan Manageable Switch dan belum dapat digunakan untuk Wi-fi dan Unmanageable Switch.

The processing needs for the High Luminosity (HL) upgrade for the LHC require the CMS collaboration to harness the computational power available on non-CMS resources, such as High-Performance Computing centers (HPCs). These sites often limit the external network connectivity of their computational nodes. In this paper we describe a strategy in which all network connections of CMS jobs inside a facility are routed to a single point of external network connectivity using a Virtual Private Network (VPN) server by creating virtual network interfaces in the computational nodes. We show that when the computational nodes and the host running the VPN server have the namespaces capability enabled, the setup can run entirely on user space with no other root permissions required. The VPN server host may be a privileged node inside the facility configured for outside network access, or an external service that the nodes are allowed to contact. When namespaces are not enabled at the client side, then the setup falls back to using a SOCKS server instead of virtual network interfaces. We demonstrate the strategy by executing CMS Monte Carlo production requests on opportunistic non-CMS resources at the University of Notre Dame. For these jobs, cvmfs support is tested via fusermount (cvmfsexec), and the native fuse module.

Digital libraries have been widely applied in educational institutions in Indonesia as a complement conventional libraries. The purpose of this research is to know division computer network access at the Adisutjipto Intitute of Technology (STTA) library. The research method used is a qualitative method using Prepare Plan Design Implement Operate and Optimize (PPDIOO). The result research is that people who have internet access will not be able to enter the digital library network. Computer network users who want to access digital libraries must log into the computer network that provides digital books in the library using a Virtual Local Area Network (VLAN). Making this VLAN requires a computer network infrastructure in the form of a Local Area Network (LAN) and computer network equipment in the form of a switch that can be used to configure multiple VLANs in a LAN. Some of the existing services in the library are placed on one VLAN and the digital library is placed on another VLAN. From the test results, it can be seen that between computers that provide services in the library on VLAN 2 cannot communicate via the connecting network to VLAN 1 where the digital library with website based services will be located. This is evidenced by the ping command which generates request time out information. VLANs network in the STTA library have been able to provide support for plans to improve services to members and academicians in the form of a digital library.

Abstract Unemployment is a serious challenge that has been rising day by day. Skill development and creation of employment opportunities are key factors to address youth unemployment. This study emphasizes on the need for job-oriented education and to link education to employment. This study derives a mathematical model and tests the same using live university hiring data and attempts to integrate the three stakeholders, employers, education providers, and the young, each of whom have a unique approach, expectation, and understanding of the paradigm. Novel methodology inclusive of empirical evidence-based integration of objective fulfillment drafted into institutional pedagogy can help increase the success rate of education to employment from an Indian context especially Indian girls and women. The study outlines specific aspects of analytical intervention in this regard and focus-es on systematic training programs exclusively for vocational and skills amelioration executed to ad-dress this multidimensional challenge by adopting easily implementable software methodologies that are more easily implementable over a wide area network or an Internet-based application engine powered by information communication technology.
