Grid-based dynamic electronic publication: a case study using combined experiment and simulation studies of crown ethers at the air/water interface.

Conventional paper-based scientific publications are limited in the amount of data and interaction they can provide. Simply placing an electronic copy of such a publication on the web makes for easier distribution, but more can be achieved by making use of the technology to navigate through the paper, to show the links between calculated parameters and the data, and provide access to the chain of calculated results all the way back to the raw data and ultimately the laboratory notebook. While the paper version of this publication is in a relatively conventional form, an interactive demonstrator version (available at http://epaper.combe.chem.soton.ac.uk and as an installable package) illustrates the concepts of publication@source, whereby all the figures and data presented in the paper are linked back to the original raw data together with a description of the processes by which the raw data were analysed. This level of interactivity is achieved using semantic technologies, which have the additional advantage of making the final document subsequently available and navigable by automated techniques. We present the combined information from experimental studies of surface tension and second harmonic generation (SHG) on the behaviour of benzo-15-crown-5 at the solution/air interface, together with a molecular dynamics computer simulation, to demonstrate how the simulation aids the interpretation of the SHG experiment. The adsorption isotherm was determined using SHG and fitted to a Langmuir isotherm giving Delta ads G0=26 kJ mol-1.

Two distinct approaches to crystallization results-recording databases.

Two different systems for recording crystallization results are described. Both programs are written in Microsoft Excel. Results can be entered either as text or numerical scores. In each system, one can search or query on the results, macromolecule name, experimental parameters, etc. and correlate these to specific crystallization conditions or trends in the crystallizations. Such information is valuable when optimizing crystal growth conditions and determining new crystallization parameters to test. XTAL RES is a Macintosh program that is linked to PCRYSTAL (software used to enter details of the crystallization experiments) through an Oracle database on a VAX network. A second system, the Electronic Notebook, was designed as a 'stand-alone' Excel application running under Microsoft Windows.

Accuracy and reliability testing of a portable soft tissue indentor.

We have designed, built, and tested a portable indentor device that allows us to determine force/displacement (F/D) measurements on soft tissue in a clinical or research setting. The indentor system consists of a load cell mounted on a three-dimensional measurement device (Metrecom). The output of the load cell and the Metrecom are recorded and analyzed by software running on a notebook computer. The displacement calibration of the Metrecom gave an average error = 0.005 mm [standard deviation (SD) = 0.062)]. The force calibration of the load cell resulted in an average error = 0.022 N (SD = 0.049) and a linearity of 1.0062 (R2 = 0.9998). The indentor device was tested on six different human soft tissues by two different investigators. The interreliabilities and intrareliabilities were 0.99 [interclass correlation (ICC)] indicating that the results were repeatable by more than one investigator. F/D measurements from indentor testing on two materials were comparable to values measured using an Instron device (5.34 versus. 5.52 N/mm, and 0.98 versus 1.04 N/mm). The device was used to measure the soft tissue characteristics on the plantar surface of the foot of one subject. These data were used to calculate the effective Young's modulus for the tissue using equations derived by Zheng et al. [1] and indicated a wide range of values dependent upon the portion of the F/D curve used. All results indicate data from this portable indentor device are reliable, accurate, and sensitive enough to identify mechanical properties of human tissues.

A rate-controlled indentor for in vivo analysis of residual limb tissues.

A tissue tester was designed to enable rate-controlled indentation of the bulk soft tissues of lower extremity residual limbs. The tissue tester employs a digital linear actuator that implements rate-controlled indentation, and a load cell that measures the reaction force resulting from tissue indentation. Viscoelastic phenomena such as preconditioning, hysteresis and force relaxation can be assessed, and the effect of varying indentation rates on soft tissue stiffness can be investigated. The device accommodates indentor excursions up to 30 mm, indentation at rates of 0 to 10 mm/s, reaction forces up to 44 N, and multiple loading/unloading cycles. The tissue tester is controlled via a notebook personal computer with a PCMCIA data acquisition card. The tissue testing trials are automated and the entire test system is portable and amenable for use in a clinical or research environment. System output consists of force-displacement curves from cyclic loading, and force-time curves following ramped-step indentation. The mean indentor positioning error was 0.071 (+/-0.75)% of the desired displacement. This error varied as a function of indentation and was approximately independent of the indentation rate. Indentation rates were accurate to within 0.94(+/-0.68)% of the desired value and also varied with indentation. Indentation of a viscoelastic foam yielded force-displacement curves that were consistent with that obtained from an Instron universal testing machine.

Wireless health care service system for elderly with dementia.

The purpose of this paper is to integrate the technologies of radio frequency identification, global positioning system, global system for mobile communications, and geographic information system (GIS) to construct a stray prevention system for elderly persons suffering from dementia without interfering with their activities of daily livings. We also aim to improve the passive and manpowered way of searching the missing patient with the help of the information technology. Our system provides four monitoring schemes, including indoor residence monitoring, outdoor activity area monitoring, emergency rescue, and remote monitoring modes, and we have developed a service platform to implement these monitoring schemes. The platform consists of a web service server, a database server, a message controller server, and a health-GIS (H-GIS) server. Family members or volunteer workers can identify the real-time positions of missing elderly using mobile phone, PDA, Notebook PC, and various mobile devices through the service platform. System performance and reliability is analyzed. Experiments performed on four different time slots, from three locations, through three mobile telecommunication companies show that the overall transaction time is 34 s and the average deviation of the geographical location is about 8 m. A questionnaire surveyed by 11 users show that eight users are satisfied with the system stability and 10 users would like to carry the locating device themselves, or recommend it to their family members.

Developing wearable bio-feedback systems: a general-purpose platform.

Microprocessors, even those in PocketPCs, have adequate power for many real-time biofeedback applications for disabled people. This power allows design of portable or wearable devices that are smaller and lighter, and that have longer battery life compared to notebook-based systems. In this paper, we discuss a general-purpose hardware/software solution based on industrial or consumer devices and a C++ framework. Its flexibility and modularity make it adaptable to a wide range of situations. Moreover, its design minimizes system requirements and programming effort, thus allowing efficient systems to be built quickly and easily. Our design has been used to build two brain computer interface systems that were easily ported from the Win32 platform.

Three centuries of stomach symptoms in Scotland.

BACKGROUND: Stomach pain and discomfort have been reported since antiquity. AIM: To follow the time trends since the 18th century of dyspepsia, gastric ulcer, duodenal ulcer, and benign oesophageal disease to test when dyspepsia started to become a major clinical problem. METHODS: The annual in- and out-patient records of the last three centuries from the Scottish Royal Infirmaries of Edinburgh, Aberdeen, Glasgow and Dundee were analysed. In addition, dispensary attendances, clinicians' casebooks, students' notebooks and medical texts have been scrutinized for historic statistics of upper gastrointestinal disease. RESULTS: Dyspepsia was first recorded in the 1750s and increased markedly subsequently. Such dyspepsia persisted after gastric and duodenal ulcers appeared in the late 19th century and then declined again in the late 20th century. Non-ulcer dyspepsia has remained the commonest diagnosis made after endoscopy for stomach pain in the beginning of the 21st century. CONCLUSION: The current commonest diagnosis of stomach pain, dyspepsia dates from the mid-18th century. Any explanations of its causation need to consider this timing.

Quality of life and attitudes towards psychotropics and dependency: consumers vs. non-consumers aged 50 and over.

AIM: To assess the relationships between socio-demographic factors, quality of life and attitudes towards psychotropic drugs and dependency and to compare those relationships in continuous consumers (CC), occasional consumers (OC) and non-consumers (NC) of those drugs. METHODS: Quality of life (SF36) and attitudes (14 statements) were measured in 601 subjects (45-60 years old) from the SUVIMAX cohort (SUpplementation en VItamines et en sels Mineraux AntioXydants). Data were obtained on 334 NC, 142 CC, 125 OC from the inclusion questionnaire and the monthly consumption report notebooks kept by subjects between 1994 and 1998. Dichotomous and polychotomous logistic regressions were used for the analysis. RESULTS: The lower the quality of life score the more frequent was consumption. NC tended to be men, with high quality of life scores. They entertained negative attitudes towards psychotropics and dependency. OC tended to be women reporting a chronic pathology, with fairly high social status. They had intermediate quality of life and denied dependency. CC tended to be men with no professional activity and low quality of life scores in particular for mental health and perceived health. They had positive attitudes towards psychotropics and accept dependency. DISCUSSION: Assessment of patients' quality of life and understanding of their attitudes towards psychotropics can provide essential information for those in charge of health promotion programmes and may help in identifying new intervention strategies. Preventive education and follow-up of therapy may be better suited to the needs of patients.

x-y-recording in transmission electron microscopy. A versatile and inexpensive interface to personal computers with application to stereology.

An interface for IBM XT/AT-compatible computers is described which has been designed to read the actual specimen stage position of electron microscopes. The complete system consists of (i) optical incremental encoders attached to the x- and y-stage drivers of the microscope, (ii) two keypads for operator input, (iii) an interface card fitted to the bus of the personal computer, (iv) a standard configuration IBM XT (or compatible) personal computer optionally equipped with a (v) HP Graphic Language controllable colour plotter. The small size of the encoders and their connection to the stage drivers by simple ribbed belts allows an easy adaptation of the system to most electron microscopes. Operation of the interface card itself is supported by any high-level language available for personal computers. By the modular concept of these languages, the system can be customized to various applications, and no computer expertise is needed for actual operation. The present configuration offers an inexpensive attachment, which covers a wide range of applications from a simple notebook to high-resolution (200-nm) mapping of tissue. Since section coordinates can be processed in real-time, stereological estimations can be derived directly "on microscope". This is exemplified by an application in which particle numbers were determined by the disector method.

A new computer network system for communicating perinatal decision support information via a telephone line.

OBJECTIVE: For fetal monitoring and assessment of high risk mother and fetus at regional hospitals, we developed a new computer network system. METHODS: The system incorporates a notebook-type personal computer (PC-9801nv) at regional hospital for communication in with 3 servers (IBM5580-YOC) connected via 2 Ethernet LANs to 2 host computers (IBM3080, IBM3174) and 5 workstations (IBM5521 V2b), and transmits the compressed data by telephone. When the data arrive, the doctor in perinatal center can immediately display and interpret the data on his workstation and give appropriate advice to the doctor at the regional hospital. RESULTS: The rate of reliable data transmission was 100%. Each 1 hour recording session and characteristic perinatal information was transmitted in less than 2 minutes. Regional medical institutions can easily access the center, and thereby can receive both simplified automatic diagnosis by fetal cardiotocography and pregnancy-risk evaluation. CONCLUSIONS: Because this system uses telephone circuits, it can be accessed from all regions of the country. Thus, our system is useful for perinatal management of high risk mother and fetus.

Error classification in community optometric practice - a pilot project.

OBJECTIVE: A pilot study was conducted to undertake a baseline assessment of errors reported in community optometric practice. The feasibility and acceptability of a method for recording staff-reported errors in optometric community practice was investigated. DESIGN: An anonymous self-reporting system was introduced in order to collect information regarding errors/untoward events in community optometric practice. SETTING: UK community optometric practice. MAIN OUTCOME MEASURES: Classification of errors according to a previously published study pertaining to general medical practice in the same geographical area. RESULTS: Thirty-six notebooks were distributed to 10 participating community optometric practices. At the end of the 1 month study period the note books were returned and the 439 entries made were classified into seven categories: optical prescriptions (18.2%), communication (35.5%), administrative (15%), appointments (2.3%), equipment (11.9%), clinical (10.3%) and other (6.9%). CONCLUSION: A previously developed classification of errors in general medical practice was found to be equally applicable to community optometric practice. This study forms the basis of providing an acceptable and practical methodology, which can be applied by Primary Care Trusts (PCTs) when developing their risk management strategy to include optometry.

Improving the timeliness of written patient notification of mammography results by mammography centers.

Timely reporting of mammogram results helps to reduce anxiety for women with negative results and speeds up diagnosis or treatment in the case of abnormal results. The goal of this project was to improve the rate at which Virginia mammography centers provide a written report to women in lay terms within 30 days of a mammogram. The project included six intervention and five control mammography centers. The baseline period was prior to when new regulations in the Mammography Quality Standards Act (MQSA) took effect in April 1999. The re-measurement period was after April 1999. Data were obtained from abstraction of mammography reports and patient notification letters from a sample of patients with negative and abnormal mammography results at each mammography center. Each intervention mammography center received a notebook that included numerous tools on systems for patient notification and tracking, baseline notification rates and other abstracted information, biopsy recommendations, sample results letters, and a copy of the MQSA. For negative mammograms, the intervention group in aggregate increased from 24% at baseline to 79% at re-measurement in their rate of notification within 30 days. The control group increased from 25% to 46%. For abnormal mammograms, increases were from 35% to 85% and from 25% to 58%, respectively. The intervention group's increases were considerably higher, suggesting an effect due to the interventions that involved technical assistance, education, and system change. All increases were statistically significant (p < 0.01). At baseline, three intervention centers and two controls had policies for written notification. All 11 had policies at re-measurement. However, only two of the five control centers could provide clear supporting documentation for dates of notification at re-measurement. Mammography centers can benefit from guidance in the form of intervention materials specifically designed to address the MQSA sections that apply to patient notification, tracking, and positive predictive value of biopsy recommendations.

Method for coding data on protozoan strains for computers.

Traditionally, observations on the nature of protozoa have been published in periodicals or books, or remain buried in research notebooks. The retrieval and processing of information on a particular species or strain are dependent solely upon individual investigators. Although various modern methods have been applied to the study of protozoa, no attempt has been made to develop a system with which information on protozoan strains can be stored, retrieved easily, and processed for various analyses by computer technology. Based upon an existing system for encoding data on bacterial strains, a complementary system applicable to protozoan strains was developed and is described herein.

The School Health Portfolio System: a new tool for planning and evaluating coordinated school health programs.

The School Health Portfolio System (SHPS), developed originally to evaluate the Florida Coordinated School Health Program Pilot Schools Project, offers a new and innovative system for planning and evaluating a coordinated school health program at the individual school level. The SHPS provides practitioners a detailed but easy-to-use system that enables schools to create new programs or modify existing programs across all eight components of the CSHP model, as well as administrative support critical to sustainability. The System comes packaged as a self-contained, notebook-style manual divided into 15 sections. It includes electronic templates of key documents to guide school teams in creating a customized portfolio, and a list of sample goals and artifacts that confirm achievement of a goal related to the school's coordinated school health program. An evaluation rubric provides a structured method to assess a program portfolio's contents, and the extent to which the contents document achievement of program goals. The rubric produces both a qualitative assessment, such as a narrative summary of program strengths and areas for improvement, and a quantitative assessment, such as a numerical score (0-100), letter grade (A-F), or 5-star system (*-*****). The physical structure, function, and scoring of the rubric depend on the method of assessment. The SHPS enables schools to set goals based on individual school needs, and incorporate CSHP goals into school improvement plans--a critical factor in sustainability and accountability. The System also offers teams the option of coordinating their efforts with CDC's School Health Index as a companion assessment measure. This article outlines the process a team would follow in developing a portfolio, and includes a sample assessment for the area of School Health Education.

Building a virtual network in a community health research training program.

OBJECTIVE: To describe the experiences, lessons, and implications of building a virtual network as part of a two-year community health research training program in a Canadian province. DESIGN: An action research field study in which 25 health professionals from 17 health regions participated in a seven-week training course on health policy, management, economics, research methods, data analysis, and computer technology. The participants then returned to their regions to apply the knowledge in different community health research projects. Ongoing faculty consultations and support were provided as needed. Each participant was given a notebook computer with the necessary software, Internet access, and technical support for two years, to access information resources, engage in group problem solving, share ideas and knowledge, and collaborate on projects. MEASUREMENTS: Data collected over two years consisted of program documents, records of interviews with participants and staff, meeting notes, computer usage statistics, automated online surveys, computer conference postings, program Web site, and course feedback. The analysis consisted of detailed review and comparison of the data from different sources. NUD*IST was then used to validate earlier study findings. RESULTS: The ten key lessons are that role clarity, technology vision, implementation staging, protected time, just-in-time training, ongoing facilitation, work integration, participatory design, relationship building, and the demonstration of results are essential ingredients for building a successful network. CONCLUSION: This study provides a descriptive model of the processes involved in developing, in the community health setting, virtual networks that can be used as the basis for future research and as a practical guide for managers.

Peter Holland: a pioneer of occupational medicine.

The earliest recorded occupational health service in this country was that established in a cotton spinning factory at Quarry Bank Mill in Cheshire. The mill was built in 1784 by Samuel Greg and his partners. They employed local labour and also some parish apprentices. Happily, Samuel Greg was a good christian and, having created a modern factory and a model village with a church and a school, he was equally concerned for the physical welfare of his employees. Accordingly, he appointed a doctor to make pre-employment examinations of the apprentices and to visit regularly to deal with the health problems of a community of some 400 people. The man he chose was Peter Holland of Sandlebridge, who had served his medical apprenticeship under Dr Charles White of Manchester. The first record of the employment of a doctor was in 1796, but from 1804 to 1845 (doubtless in response to the early factory legislation) each visit of the doctor was entered in a day book with either an indication of fitness to work or details of the treatment required. The complete record consists of two hardback foolscap notebooks that provide a fascinating insight into the medical practice of the times when the industrial revolution was just getting under way. One of the more interesting features is the preservation of medical secrecy. Dr Holland made his comments on the case in shorthand and his instructions in longhand. By a fortunate coincidence the key to the shorthand was discovered and this has now been largely transcribed. Although much of the content of the diaries is the day by day practice of medicine at the time, there are many illuminating glimpses of the early practice of occupational medicine.
