Use of COSREEL, a computerised recording system, for herd health management of two dairy herds.

COSREEL, a computerised animal health recording system, has been used since October 1980 by two agricultural colleges for the management of their dairy herds. Each college and the veterinary practice which served the college has had its own typewriter terminal connected to a remote computer. Management and milk data have been coded and entered at the college and clinical data at the veterinary practice. An average of just over one management and veterinary event per week has been coded for every three cows in milk. Error rates were on average 11 per cent by one pair of users and 4 per cent by the other pair. COSREEL has provided a valuable aid to the management of the health of the two herds, and the regular use of pregnancy diagnosis, infertility investigation and oestrus detection action lists resulted in a considerable improvement in herd fertility at the two colleges.

Clinical evaluation of the rapid telephone access system for radiology reporting.

The Rapid Telephone Access System (RTAS) for radiology reporting was evaluated clinically among patients undergoing fluoroscopy, excretory urography, or cholecystography at a community-based teaching hospital. After the radiologist has dictated his report in the customary manner, it can be heard by the referring physician using any telephone. Reports can be reduced to hard copy by a typist, or an automatic typewriter can be programmed to print normal or standard reports. Time between dictation and access of the report was significantly reduced after installation of the RTAS (p less than 0.001). There was also a trend toward reduced hospital stay (p less than 0.05) for patients in the study group. The system has been readily accepted by radiologists and referring physicians.

Right unilateral agraphia following callosal infarction in a left-hander.

A left-handed Japanese man is reported who presented right-hand agraphia and tactile anomia following callosal infarction. Magnetic resonance imaging revealed an ischemic lesion extending from the posterior half of the trunk to the splenium of the corpus callosum. In his right handwriting, the 'Kana' (phonogram) was more severely impaired than the 'Kanji' (ideogram), and the most frequent typewriting error was morphological followed by neographism. His visuoconstructional ability was also more impaired in the right hand than in the left. Right-hand agraphia in our case is readily explained by the right hemisphere dominance both for language and visuoconstructional ability.

Nondyslexic children with combined writing and arithmetic learning disabilities.

A common presenting problem of children in pediatric practice is the constellation of symptoms involving difficulty in completing assignments, trouble with written work, and organizational problems. Typically, these children do not have difficulty with reading but show problems with academic achievement. We have recently studied 29 children, aged 7 to 13, referred for learning problems. They were not dyslexic, that is their reading abilities were normal, but they had significant difficulty with written tests and assignments and problems with arithmetic. In addition to difficulty with eye-hand coordination as measured by a test of visual motor integration, these children showed poor performance on short-term memory tasks when compared with children who do not have writing or arithmetic problems. Suggested treatments include the use of tape recorders, typewriters, and calculators to help compensate for the writing and short-term memory difficulties associated with these learning problems. The pediatrician, acting as child advocate, can exert influence within the traditional school system to gain acceptance for use of learning aids by children with a developmental output disability.

The effects of competition on achievement motivation in Chinese classrooms.

BACKGROUND: Laboratory studies have consistently found that competition induces performance goals and affects learning motivation. However, the ecological validity of these results is yet to be established. There is a need for investigation of whether the results hold in both the classroom context and non-Western culture. AIM: The study investigated the effects of competition on learning motivation among Chinese students in an authentic classroom setting. SAMPLE: The participants were 52 students of grade 7 from two Hong Kong secondary schools. METHOD: They were randomly assigned to either competitive or non-competitive conditions in a 2-hour Chinese typewriting course. RESULTS: Students in the competitive condition performed better in easy tasks than their counterparts in the non-competitive condition. However, they were more performance-oriented and more likely to sacrifice learning opportunities for better performance. They were also prone to have worse self-evaluation after failure. Although there were no statistically significant differences between the two conditions in task enjoyment and achievement attribution, the direction of the differences was consistently unfavourable to students in the competitive condition. CONCLUSION: The findings were consistent with the predictions of goal theory. Competitiveness induces performance goals and worse self-evaluation after failure among Chinese students in a classroom setting, as was found with Western students in a laboratory setting.

[Electroencephalography measures in motor skill learning and effects of bromazepam].

Neuromodulators change brain's neural circuitry. Bromazepam is often been used in the pharmacological treatment of anxiety disorders. Few papers links this anxiolytic to motor tasks. The purpose of this study was to examine motor and electrophysiological changes produced by administration of bromazepam in differents doses (3 and 6 mg). The sample consisted of 39 healthy individuals, of both sexes, between 20 and 30 years of age. The control (placebo) and experimental (bromazepam 3mg and bromazepam 6 mg) groups were submitted to a typewriting task, in a randomized, double-blind design. The results did not reveal differences on score and time of the attention test. In the comportamental analysis was noticed blocks as main effect to behavioral variables (time and mistakes in the task). Electrophysiological data showed significants interactions to: laterally/condition/moment; laterally/condition; laterally/moment; condition/moment; condition/site.

[Effects of Bromazepam in qEEG by type writing].

The efficiency with which an information is processed by the brain's neural circuitry can be altered by neuromodulators. The use of Bromazepam in the pharmacological treatment of anxiety disorders is due to its anxiolytic property. However, the effects of this benzodiazepine in motor learning tasks are not entirely understood. In this context, the goal of this study was to assess the effects of Bromazepam (6 mg) on psychophysiological, behavioral, and electrophysiological variables, during the process of learning a motor task. The sample consisted of 26 healthy individuals, of both sexes, between 19 and 36 years of age. The control (placebo) and experimental (Bromazepam 6 mg) groups were submitted to a typewriting task, in a randomized, double-blind design. The results did not reveal differences for phychophysiological and behavioral variables between the groups. Statistical tests pointed out to an interaction between condition and moment, and a hemisphere main effect, i.e. a reduction of relative power in the right hemisphere. This reduction suggests a specialization of the neural circuitry in the hemisphere contralateral to the finger used in the task. Such reduction is independent from the drug administration.

[Neuromodulatory effects of bromazepam when individuals were exposed to a motor learning task: quantitative electroencephalography (qEEG)].

The sedative effects of bromazepam on cognitive and performance have been widely investigated. A number of different approaches have assessed the influence of bromazepam when individuals are engaged to a motor task. In this context, the present study aimed to investigate electrophysiological changes when individuals were exposed to a typewriting task after taking 6 mg of bromazepam. qEEG data were simultaneously recorded during the task. In particular, relative power in delta band (0.5-3.5 Hz) was analyzed. Time of execution and errors during the task were registered as behavioral variables. The experimental group, bromazepam 6 mg, showed a better motor performance and higher relative power than control individuals (placebo). These results suggest that the use of bromazepam reduces anxiety levels as expected and thus, produces an increment in motor performance.

[Procedural learning and anxiolytic effects: electroencephalographic, motor and attentional measures].

The objective of the present study was to evaluate attentional, motor and electroencephalographic (EEG) parameters during a procedural task when subjects have ingested 6 mg of bromazepam. The sample consisted of 26 healthy subjects, male or female, between 19 and 36 years of age. The control (placebo) and experimental (bromazepam 6 mg) groups were submitted to a typewriting task in a randomized, double-blind design. The findings did not show significant differences in attentional and motor measures between groups. Coherence measures (qEEG) were evaluated between scalp regions, in theta, alpha and beta bands. A first analysis revealed a main effect for condition (Anova 2-way--condition versus blocks). A second Anova 2-way (condition versus scalp regions) showed a main effect for both factors. The coherence measure was not a sensitive tool at demonstrating differences between cortical areas as a function of procedural learning.

An introduction to the clinical toxicology of volatile substances.

Acute poisoning with organic solvents and other volatile compounds now usually follows deliberate inhalation (volatile substance abuse) or ingestion of these compounds. Solvents from adhesives, typewriter correction and dry cleaning fluids, cigarette lighter refills (butane) and aerosol propellants are commonly abused. The major risk is that of sudden death. Arrhythmias leading to cardiac arrest are thought to cause most deaths, but anoxia, respiratory depression and vagal stimulation leading to cardiac arrest may also contribute, as may indirect causes such as aspiration of vomit or trauma. In the United Kingdom (UK), 3.5 to 10% of young people have at least experimented with volatile substance abuse and mortality is more than 100 per annum. The products abused are cheap and readily available despite legislation designed to limit supply. Volatile substance abuse is not illegal and only a minority of abusers are known to progress to heavy alcohol or illicit drug use. Prevention of abuse by education, not only of children but also of parents, teachers, retailers and health care workers, is important in limiting the problem. However, volatile substance abuse-related deaths are still increasing in the UK despite many measures aimed at prevention. Clinically, volatile substance abuse is characterised by a rapid onset of intoxication and rapid recovery. Euphoria and disinhibition may be followed by hallucinations, tinnitus, ataxia, confusion, nausea and vomiting. It is important not to further alarm the patient if signs of serious toxicity are present, since a cardiac arrest may be precipitated. Further exposure should be prevented and the patient resuscitated and given supplemental oxygen if necessary. Cardiac arrhythmias should be treated conventionally and respiratory failure managed supportively. Long term exposure to n-hexane is associated with the development of peripheral neuropathy, while prolonged abuse (notably of toluene or chlorinated solvents) can cause permanent damage to the central nervous system, heart, liver, kidney and lungs. Knowledge of the routes of absorption, distribution and excretion of volatile compounds, and of the rates governing these processes, is important in understanding the rate of onset, intensity and duration of intoxication, and rate of recovery after volatile substance abuse. In addition, such knowledge is helpful when the clinician is attempting to interpret the results of toxicological analyses performed on samples (blood, other tissues, urine) from such patients. Many volatile substances are partly metabolised, the metabolites being eliminated in exhaled air or in urine. Although metabolism normally results in detoxification, enhanced toxicity may also result as with carbon tetrachloride, chloroform, dichloromethane, n-hexane, trichloroethylene and possibly halothane.(ABSTRACT TRUNCATED AT 400 WORDS)

A quantitative model for designing keyboard layout.

This study analyzed the quantitative relationship between keytapping times and ergonomic principles in typewriting skills. Keytapping times and key-operating characteristics of a female subject typing on the Qwerty and Dvorak keyboards for six weeks each were collected and analyzed. The results showed that characteristics of the typed material and the movements of hands and fingers were significantly related to keytapping times. The most significant factors affecting keytapping times were association frequency between letters, consecutive use of the same hand or finger, and the finger used. A regression equation for relating keytapping times to ergonomic principles was fitted to the data. Finally, a protocol for design of computerized keyboard layout based on the regression equation was proposed.

A computerized semi-automatic evaluation system for quantitation of electroimmunoassays.

A fast and accurate evaluation system for quantitation of plasma proteins from electroimmunoassay plates is described. The protein concentration is determined from the height of its stained antigen-antibody precipitate by means of a coordinate digitizer connected to a COMPUCORP 445 minicomputer. The plasma protein concentration is calculated from the equation of the best second-order least square regression of data from a standard dilution curve. The values from one type of protein analysis can either be stored on a discette for future examination or printed out each day in a tabular form on a typewriter. A double evaluation of plasma concentrations from plates of two different proteins showed a coefficient of variation (CV) better than 4.5%. A correlation between values obtained by this technique and those obtained by the manual reading procedure has also been done. The correlation coefficient varied between 0.95 and 0.99 depending on the type of protein.

Moving the eyes along the mental number line: comparing SNARC effects with saccadic and manual responses.

Bimanual parityjudgments about numerically small (large) digits are faster with the left (right) hand, even though parity is unrelated to numerical magnitude per se (the SNARC effect; Dehaene, Bossini, & Giraux, 1993). According to one model, this effect reflects a space-related representation of numerical magnitudes (mental number line) with a genuine left-to-right orientation. Alternatively, it may simply reflect an overlearned motor association between numbers and manual responses--as, for example, on typewriters or computer keyboards--in which case it should be weaker or absent with effectors whose horizontal response component is less systematically associated with individual numbers. Two experiments involving comparisons of saccadic and manual parity judgment tasks clearly support the first view; they also establish a vertical SNARC effect, suggesting that our magnitude representation resembles a number map, rather than a number line.

A study of the multiple pinhole coded aperture and the application of the minicomputer in image decoding.

Research has been done on optically reconstructed imaging employing the Multiple Pinhole Coded Aperture (hereafter abreviated as MPCA) in radioisotope tomographic imaging. However, problems remain in the optically reconstructed image method. Therefore, we employed a minicomputer (hereafter abbreviated as CPU) and developed the software for decoding and managing the radioisotope tomographic image. Combining the MPCA and the CPU system, we were able to decode and manage the radioisotope tomographic image. 1) In comparison to the optically decoded MPCA image, various input commands are possibly in the CPU method according to the dialogue between the CPU and the on line typewriter. In addition to this, decoded tomographic images of unrestricted depth are readily attainable. 2) In the CPU method noise elimination and other aspects of image management can be easily performed.

Brief or new: two pronation splints.

For two years we have made pronation splints to assist quadriplegic patients who lack adequate forearm pronation but who have enough upper extremity strength to feed themselves and perform other self-care or functional activities. We have found the splints to be an appropriate alternative to the MAS. The first pronation splint fits underneath the arm, is simple in design and fabrication, and is hidden. However, occasionally the lever of the splint hangs up in the shirt, catches on the post of the wheelchair, or slips out from underneath the arm when the patient reaches away from the body. To eliminate these problems, we designed a second splint. But, this splint requires more time to make and adjust, has two parts to put on instead of one, and is more noticeable because it is worn on top of the arm rather than underneath it. When a patient uses either splint, the degree of pronation may be adjusted according to the activity by slightly rotating the splint either way when strapping it on. For example, full pronation may be required for feeding, but only half the range is necessary to operate the keyboard of a computer or typewriter. Once the Velcro straps are applied, the splints do not slip. The splints are not interchangeable from left to right and assistance is always needed to put them on. For patients with "weak" or "absent" wrist extensors, a wrist support and cuff splint may be used along with the pronation splint or a universal cuff, if wrist extension is adequate. The pronation splints are appropriate for those patients whose forearms supinate when they reach their hand to or near their mouth.

Electronic forms: a next step in hospital automation.

Information consists of two parts, facts and communication. It is not enough for one person to know a fact; the fact must be communicated for it to be of any value to anyone else. Forms were invented to do just that--communicate facts in a systematic manner from one party to the next. Automating forms with computers on a local area network or a wide area network allows for hospital personnel to input a patient's information once and electronically share the information from one department to another, simultaneously. Switching from a paper-based forms system to a fully automated workflow forms system or combining the two can save a healthcare institution money, errors, time and even lives. The levels of an automated forms system include: electronic forms design, demand printing, typewriter replacement, intelligent forms, intelligent mail and true workflow automation.

Speech-to-text: the next revelation for recording data.

There are numerous tools available for communicating and storing information. Administrators may want to consider speech-to-text-technology. Programs are available that are accurate, easy to use and easily integrated into existing hospital information systems. Computerized voice recognition systems that provide direct speech-to-text are available today and are often referred to as the "listening typewriter." You speak, the computer listens and then types out what it thinks it heard. Such a system has a vocabulary or collection of words that may be spoken by a user. The program analyzes the phonetic structure of words in the vocabulary. A database table compares sounds made by the voice to words in the vocabulary. Two types of recognition are available--realtime and deferred server-based. With realtime transcription, dictation appears on the workstation screen in front of the dictating radiologist. With the deferred system, the dictated session goes to a queue on a server and waits there to be processed, on operation often known as batch processing. Failure of the system can be prevented by clustering or having a redundant server that takes over for the primary server if it should fail. Options to consider for a speech transcription system include security for electronic signatures and a provision for quality assurance or editing professionals who will review documents for errors in recognition. Some software systems offer a program that examines the final document for new or misspelled words, while other systems require error correction to be completed within the last 10 dictated words. The distributed voice model contains a profile of users' pronunciations and allows the computer to recognize a voice that, associated with login ID, differentiates it from others. This model allows a physician to dictate from different locations. Although the cost of the hardware is impressive and requires a thorough cost benefit analysis, such a system can be an excellent solution for large institutions with several locations.

Word processing in healthcare: guidelines and a case study.

If controlling or reducing healthcare costs while providing the best possible patient service is your goal, then word processing is an auxiliary method of information processing that you should examine closely. Handled properly, word processing delivers significant benefits: improved collections, increased cash flow, reduced paperwork, increased donations to healthcare foundations, improved productivity and improved document quality. Mishandled, word processing does little more than provide you with expensive typewriters.
