A remote data access architecture for home-monitoring health-care applications.

With the aging of the population and the increasing patient preference for receiving care in their own homes, remote home care is one of the fastest growing areas of health care in Taiwan and many other countries. Many remote home-monitoring applications have been developed and implemented to enable both formal and informal caregivers to have remote access to patient data so that they can respond instantly to any abnormalities of in-home patients. The aim of this technology is to give both patients and relatives better control of the health care, reduce the burden on informal caregivers and reduce visits to hospitals and thus result in a better quality of life for both the patient and his/her family. To facilitate their widespread adoption, remote home-monitoring systems take advantage of the low-cost features and popularity of the Internet and PCs, but are inherently exposed to several security risks, such as virus and denial-of-service (DoS) attacks. These security threats exist as long as the in-home PC is directly accessible by remote-monitoring users over the Internet. The purpose of the study reported in this paper was to improve the security of such systems, with the proposed architecture aimed at increasing the system availability and confidentiality of patient information. A broker server is introduced between the remote-monitoring devices and the in-home PCs. This topology removes direct access to the in-home PC, and a firewall can be configured to deny all inbound connections while the remote home-monitoring application is operating. This architecture helps to transfer the security risks from the in-home PC to the managed broker server, on which more advanced security measures can be implemented. The pros and cons of this novel architecture design are also discussed and summarized.

An investigation into the physical accessibility to wheelchair bound students of an Institution of Higher Education in South Africa.

PURPOSE: A descriptive cross-sectional study was undertaken to establish the ease of accessibility to wheelchair bound students of the campus of a large institution of higher education in South Africa. Accessibility was defined not simply in terms of access to buildings, but also of the added time and distance traveled by wheelchair bound students on the campus. METHODS: Five different faculties were randomly selected and typical routes travelled by a first year student in each faculty established. The shortest possible distances were mapped out for each faculty and measured using a metre wheel. For those in wheelchairs, this distance included the distance to ramps and to lifts. Mean speeds were used to determine the time taken to travel the measured distances. A checklist was used to measure the physical accessibility of the 18 buildings concerned. RESULTS: The total mean distance traveled between lecture theatre changeover by wheelchair-bound students was 402 metres (range 278-689 m for the different faculties), which was a mean difference of 66 m (range 11-145 m) longer than for ambulant students. The mean time taken was 17 minutes (range 11-28 minutes), which was 11 minutes (range 8-19 minutes) longer than for ambulant students. The Faculty of Mechanical Engineering fared the worst, at 689 metres and 28 minutes between changeover. Two of the 18 buildings measured were fully accessible, while three were completely inaccessible. Inaccessible toilets were the most common problem. CONCLUSIONS: Wheelchair-bound students consistently had to travel further and for longer times between lecture theatres in all the faculties measured. The students would therefore be unable to reach their lectures within the 10 minute time allocated by the university. The inaccessibility of the buildings limits the full integration of wheelchair-bound students into campus life. Certain administrative changes might assist in improving the ease of accessibility. Architectural adaptations, although more costly, might also prove to be effective.

Minimum guidelines and requirements for accessible design--Architectural and Transportation Barriers Compliance Board. Final rule.

The Architectural and Transportation Barriers Compliance Board hereby revises its "Minimum Guidelines and Requirements for Accessible Design" (guidelines and requirements). These revisions respond to concerns registered by certain Board members and to issues raised in comments submitted during the rulemaking process. The purpose of the revisions is to make the guidelines and requirements more cost effective and consistent with Federal and nationally recognized standards while still providing ready access and use. The guidelines and requirements, as revised, will provide a basis for consistent and improved accessibility standards to be issued under the Architectural Barriers Act by the General Services Administration, the Department of Housing and Urban Development, the Department of Defense, and the United States Postal Service. For clarity, the guidelines and requirements are published in their entirety with the revisions incorporated.

Minimum guidelines and requirements for accessible design--Architectural and Transportation Barriers Compliance Board. Proposed rule.

The Architectural and Transportation Barriers Compliance Board proposes to rescind the minimum guidelines and requirements for standards for accessibility and usability of federal and federally-funded buildings and facilities by physically handicapped persons, adopted on January 6, 1981. The Board seeks public comments on which parts of the January 6 rule should be retained, which parts should be deleted, and which should be modified to formulate alternative ways for the Board to carry out its responsibility to establish such guidelines and requirements.

Attachment styles and repressive defensiveness: the accessibility and architecture of affective memories.

One hundred and twenty Israeli students were classified into secure, avoidant, and anxious-ambivalent attachment groups. They completed scales that tap the construct of repressive defensiveness and recalled early personal experiences of anger, anxiety, sadness, and happiness. Secure people reported moderate defensiveness and low anxiety and had easy access to negative memories without being overwhelmed by the spreading of the dominant emotional tone to nondominant emotions. Anxious-ambivalent people were unable to repress negative affects, reported high anxiety, had easy access to negative memories, and could not inhibit emotional spreading. Avoidant people reported high levels of defensiveness and anxiety and showed low accessibility to negative memories. The discussion emphasizes the parallel between a person's interaction with the social world and the makeup of his or her inner world.

PCASSO: a secure architecture for access to clinical data via the Internet.

Patient Centered Access to Secure Systems Online (PCASSO) is a National Information Infrastructure research project funded by the US National Library of Medicine (NLM). PCASSO is specifically designed to address the problem of enabling secure access to health information over the Internet, not just for healthcare providers and medical researchers, but also for patients to view their own medical records. The project is using familiar Web technologies to support the search and retrieval of information, including patient demographics, medications, lab tests, and transcription reports. State-of-the-art security technologies protect patient privacy and the integrity of patient information. This paper describes the security architecture of the PCASSO system.

Home modification.

Almost 50 million Americans--about one in five--live with a mental or physical disability, many in homes that are inconvenient, restrictive, or dangerous for them. Modifying the home using universal (barrier-free) design, architectural accessibility, and other such concepts can reduce the risk of falls and improve overall function. Nurses can be involved by assessing patients' living quarters and recommending specific modifications.

Dimeric DNA quadruplex containing major groove-aligned A-T-A-T and G-C-G-C tetrads stabilized by inter-subunit Watson-Crick A-T and G-C pairs.

We report on an NMR study of unlabeled and uniformly 13C,15N-labeled d(GAGCAGGT) sequence in 1 M NaCl solution, conditions under which it forms a head-to-head dimeric quadruplex containing sequentially stacked G-C-G-C, G-G-G-G and A-T-A-T tetrads. We have identified, for the first time, a slipped A-T-A-T tetrad alignment, involving recognition of Watson-Crick A-T pairs along the major groove edges of opposing adenine residues. Strikingly, both Watson-Crick G-C and A-T pairings within the direct G-C-G-C and slipped A-T-A-T tetrads, respectively, occur between rather than within hairpin subunits of the dimeric d(GAGCAGGT) quadruplex. The hairpin turns in the head-to-head dimeric quadruplex involve single adenine residues and adds to our knowledge of chain reversal involving edgewise loops in DNA quadruplexes. Our structural studies, together with those from other laboratories, definitively establish that DNA quadruplex formation is not restricted to G(n) repeat sequences, with their characteristic stacked uniform G-G-G-G tetrad architectures. Rather, the quadruplex fold is a more versatile and robust architecture, accessible to a range of mixed sequences, with the potential to facilitate G-C-G-C and A-T-A-T tetrad through major and minor groove alignment, in addition to G-G-G-G tetrad formation. The definitive experimental identification of such major groove-aligned mixed A-T-A-T and G-C-G-C tetrads within a quadruplex scaffold, has important implications for the potential alignment of duplex segments during homologous recombination.

Data security and protection in cross-institutional electronic patient records.

This paper aims at identifying the specific legal requirements concerning data security and data protection of patient health data that apply to a cross-institutional electronic patient record (EPR) and describes possible solutions for meeting these requirements. In Germany, the legal framework for such records provide that disclosure of patient health information to physicians of third-party institutions is only allowed in case that it is necessary for the joint treatment of the patient, i.e. in case of a "treatment connection". As a first step, the functionality of a remote-access architecture was proven allowing a one-way connection between the EPR systems of two health institutions in Germany, which jointly treat tumor patients. Besides, a signature system model for ensuring the integrity and authenticity of medical documents was developed and implemented in the existing information system architecture of the University Medical Center of Heidelberg. Especially in Germany, the legal framework for cross-institutional EPRs is very complex and has a considerable influence on the development and implementation of cross-institutional EPRs. However, its introduction is thought to be valuable, since a cross-institutional EPR will improve communication within shared care processes, and thus improve the quality of patient care.
