In recent years, enterprise networks have been widely used. However, due to its structure so that all access and calculation must be processed through VPN service, which appeared insufficient memory, computing speed to keep up with other issues. This article proposed some improvement based on these issues, using the improved algorithm to encrypt the ellipse. Keywords-SSL;VPN;Ellipsealgorithm

Remote access technology offers tremendous possibilities to the cytometry community

THE opportunity for low cost, high quality training and supervision is an attractive one to most scientists in the cytometry field. Many have had little if any training, no expertise based locally, or may not have the funds to attend regional or international training courses. In addition, rather than general cytometry they may require assistance with a particular application, which could be accomplished in a number of hours through support from an expert. Separately, shared resource scientists, also known as core facility staff, are generally responsible for the performance and upkeep of multiple complex instruments, as well as monitoring, training etc. Some acquisitions or cell sorts may take hours for a single run, and with limited staff the scientist is usually multitasking on an hourly basis. Also, if users of the core facility are having problems and staff is unavailable, valuable samples or time may be lost. There is potential for error at many steps of flow cytometry, including sample preparation, experimental design and fluorochrome selection, instrument set up, compensation, gating, analysis, and interpretation. External/offsite tracking may improve monitoring, and perhaps limit such errors. Also interand intra-instrumentation variations can lead to different results for the same sample. A means of unifying performance, setup, and interpretation is vital, in particular with multicenter collaborations. Peer-review of results and analysis, as well as hierarchical approval systems, provides some solutions, but further stream-lining is clearly beneficial. Remote access technology for cytometry (or remote cytometry) may offer solutions to many such issues and can be performed at very low costs to the institution. There is potential for such systems to facilitate instrumentation monitoring, control equipment in containment areas, speed up vendor service, improve training courses, increase collaborations, and further promote cytometry globally.

Enhancing Nursing Education with Remote Access Laboratories

Abstractâ??Given the vast coverage area and dispersed population centres in which nursing professionals practice in Australia, Remote Access Laboratory (RAL) based learning activities would seem to be an ideal match. However while they are commonplace in engineering faculties; in other disciplines such activities are not widely used. This may well be due to the intricacies of these practicals not being as straightforward and readily reproducible as typical physics or science experiments. 
 In our chosen case, the safe practice of intravenous pump driver operations and related clinical reasoning skills are important components for the training of both registered nurses and nursing students. The aim of this research project is to develop and trial remote access technologies that enable nursing students to test their knowledge, skills, and clinical reasoning with intravenous infusion pump drivers. This has been possible by extending the concept of RAL from a physical and tangible experiment, to more conceptual experimentation in any form conducted remotely. In such a context clinical reasoning becomes possible. 
 This paper discusses a prototype system that has been built with collaborative input from the Faculty of Engineering and Surveying and the Department of Nursing and Midwifery. An initial evaluation with a group of nursing students has been completed to assess if such activities can assist with the training of student nurses. Previous work has identified the need to scaffold learning activities that rely on RAL technology; the key conclusion in this paper is that in the context of nursing this has to be taken a step further. RAL activities here require contextualisation to become an effective learning tool.

Lifestyle-oriented non-pharmacological treatments for fibromyalgia: a clinical overview and applications with home-based technologies

Fibromyalgia (FM) is a persistent and disabling widespread pain condition often accompanied by chronic fatigue, cognitive problems, sleep disturbance, depression, anxiety, and headache. To date, the most thoroughly studied non-pharmacological approaches to managing FM are those with a focus on changing patient activities and beliefs that affect the illness. These interventions are intended to facilitate enduring improvement in pain and functional status. Lifestyle-oriented treatments include patient education, aerobic or other physical exercise, and cognitive-behavioral therapy (CBT). These interventions in FM can be delivered in medical or behavioral health care settings by trained professionals, through patient-oriented treatment manuals, or via remote-access technologies. Non-pharmacological treatments, in particular exercise and CBT, have yielded effect sizes and cost–benefit ratios comparable to medications. This paper describes lifestyle-oriented non-pharmacological treatments for FM and highlights selected literature reviews of these interventions. In addition, behavioral and practical issues are addressed that may affect these non-pharmacological treatments, including patient expectations, participant burden, and treatment availability. Recommendations are made to facilitate these interventions and potentially improve outcomes. In particular, the increasing availability of convenient home-based mobile technologies to deliver these non-pharmacological treatments is described.

A Meta-Analysis of Remote Monitoring of Heart Failure Patients

The purpose of this study was to assess the effect of remote patient monitoring (RPM) on the outcome of chronic heart failure (HF) patients. RPM via regularly scheduled structured telephone contact between patients and health care providers or electronic transfer of physiological data using remote access technology via remote external, wearable, or implantable electronic devices is a growing modality to manage patients with chronic HF. After a review of the literature published between January 2000 and October 2008 on a multidisciplinary heart failure approach by either usual care (in-person visit) or RPM, 96 full-text articles were retrieved: 20 articles reporting randomized controlled trials (RCTs) and 12 reporting cohort studies qualified for a meta-analysis. Respectively, 6,258 patients and 2,354 patients were included in RCTs and cohort studies. Median follow-up duration was 6 months for RCTs and 12 months for cohort studies. Both RCTs and cohort studies showed that RPM was associated with a significantly lower number of deaths (RCTs: relative risk [RR]: 0.83, 95% confidence interval [CI]: 0.73 to 0.95, p = 0.006; cohort studies: RR: 0.53, 95% CI: 0.29 to 0.96, p < 0.001) and hospitalizations (RCTs: RR: 0.93, 95% CI: 0.87 to 0.99, p = 0.030; cohort studies: RR: 0.52, 95% CI: 0.28 to 0.96, p < 0.001). The decrease in events was greater in cohort studies than in RCTs. RPM confers a significant protective clinical effect in patients with chronic HF compared with usual care.

Remote Laboratories for Optical Circuits

This paper presents a remote laboratory implementation for an optical circuits course. The process from design and implementation towards assessment and continuous improvement phase is outlined. The design of the experiments involved the research on remote access technology and the investigation of best practices for an experimental setup. The first pilot implementations were used to determine the possible shortfalls during an ldquoIntroduction to an Optical Communicationsrdquo course in fall 2004 at the University of Colorado, Boulder, and an ldquoOptical Circuitsrdquo course in fall 2005 at the University of Houston, Houston, TX. After improvements, two experiments were pilot tested during spring 2006 at the University of Houston. Assessment of learning outcomes and teaching methods were performed. The remote access methods, in addition to the delivery of the class and lectures, are presented in the paper. Delivery of a class with remote laboratories and videotaped lectures are also outlined under future directions of this project.

The development and deployment of a multi-user, remote access virtualization system for networking, security, and system administration classes

We have combined four industry standard technologies to create a flexible, modular and easily extensible virtual server environment for both distance and local students to use in our networking, security, and system administration classes. By combining the remote access technologies of Remote Desktop, the multi-user capabilities of Microsoft Terminal Services, the ability to share sessions of Remote Assistance, and the ability to manipulate virtual machines and virtual networks using VMWare Workstation, the Remote Laboratory Emulation System (RLES) allows students to conduct labs very similar to our local labs from either inside or outside our lab facility. While other people have been experimenting with various combinations of these technologies we have aggressively developed and implemented this system and feel that it has become a very important tool in our ability to cost-effectively provide computing infrastructure for local and distant students, and student and faculty research.

Remote access to a web-based image distribution system

To assess different network and security technologies for remote access to a web-based image distribution system of a hospital intranet. Following preparatory testing, the time-to-display (TTD) was measured for three image types (CR, CT, MR). The evaluation included two remote access technologies consisting of direct ISDN-Dial-Up or VPN connection (Virtual Private Network), with three different connection speeds of 64, 128 (ISDN) and 768 Kbit/s (ADSL-Asymmetric Digital Subscriber Line), as well as with lossless and lossy compression. Depending on the image type, the TTD with lossless compression for 64 Kbit/s varied from 1 : 00 to 2 : 40 minutes, for 128 Kbit/s from 0 : 35 to 1 : 15 minutes and for ADSL from 0 : 15 to 0 : 45 minutes. The ISDN-Dial-Up connection was superior to VPN technology at 64 Kbit/s but did not allow higher connection speeds. Lossy compression reduced the TTD by half for all measurements. VPN technology is preferable to direct Dial-Up connections since it offers higher connection speeds and advantages in usage and security. For occasional usage, 128 Kbit/s (ISDN) can be considered sufficient, especially in conjunction with lossy compression. ADSL should be chosen when a more frequent usage is anticipated, whereby lossy compression may be omitted. Due to higher bandwidths and improved usability, the web-based approach appears superior to conventional teleradiology systems.

The Virtual Medical Library

Most academic health sciences libraries have developed impressive digital collections of journals and books over the past few years. These resources constitute a strong core collection of library resources, easily accessible to campus users anytime, day or night. Remote access proxy servers and other remote access technologies allow affiliated students, staff, and faculty to use these resources from the home, office, or remote clinical locations, virtually anywhere there is access to the Internet. This paper provides an overview of issues related to implementing, promoting, and supporting remote access via a proxy server and selected issues relating to licensing and managing electronic resources. The particular experiences of the Yale University's Cushing/Whitney Medical Library are highlighted.

Network infrastructure security

The network is only as secure as its weakest access point. At one extreme we have the totally open network with every user having open access to every area of the network. At the other we have the ultimate secure network with no user connections so that there are no insecure access points! Somewhere in between we have a balance in the security provided to maintain an easy to use and accessible network whilst reducing the risk of breaches to security. Today computing networks span the world with thousands of entry points. Remote access technologies and the Internet or corporate intranets further extend the network to include remote and mobile users. Whilst these technologies heighten the productivity of the organization they also increase the security risks.

Total quality management and servicing users through remote access technology

For as long as libraries and information centers have existed, the services they have offered to their constituents have been provided, utilized and monitored on a person‐to‐person basis. This individual and direct interaction has ensured an active vendor/consumer dialog which has not only fostered a successful transfer of information but also provided a forum through which to evaluate user needs and service quality. This one‐on‐one communication flow has been of invaluable assistance to the professional in assuring that clients and customers receive accurate, clear, concise, complete and timely responses to information inquiries. In addition, it has affected a critical check‐in‐balance on the value and viability of collections and databases in meeting service demands. It was through this traditional reference and information interview that direct user impact on the service process could be guaranteed and a high degree of quality achieved.
