Simple device for the tape recording of complex behavioral situation on one track.

A low cost electronic device is described to record on one a.m. tape track the occurrence of any combination of four signals. The fast read out of recorded signals makes the apparatus reliable and helpful for coding behavioral situation and automatic averaging of event related phenomena. A detailed circuitry is included and discussed.

[The use of tape recorders in classes with motor handicapped pupils (author's transl)].

It is demonstrated that physical disabilities involving motor deficits automatically result in communicative limitations which become particularly evident in calsses. As a rule, the consequences of a slow writing performance due to physical disability are a decrease in performance. The supply of intellectually normal but severely physically handicapped pupils with adequate technical aids designed to compensate for their disabilities is, therefore, a necessity which improves their educational opportunities. With the help of an adjusted and technically supplemented tape recorder it is demonstrated in how far a technical apparatus can become the "tool" of a special education teacher.

Exploring the effects of tape-recording on personality assessment.

This study examined the possible influence of audio and video recording of personality assessment measures on anxiety. Undergraduate students in psychology were randomly assigned to Audiotape, Videotape, or Control conditions and given the State-Trait Anxiety Inventory and Rorschach Inkblot Method. A one-way multivariate analysis of variance indicated no significant differences among these conditions on the Spielberger, et al. State-Trait Anxiety Inventory, A-State scale, and five Rorschach measures of situational anxiety. Tape-recording itself did not seem to affect the anxiety indices of these frequently used personality assessments.

Interaction between emergency medical dispatcher and caller in suspected out-of-hospital cardiac arrest calls with focus on agonal breathing. A review of 100 tape recordings of true cardiac arrest cases.

AIM: One of the objectives of this study was to assess the emergency medical dispatchers (EMDs) ability for the identification and prioritisation of cardiac arrest (CA) cases, and offering and achievements of dispatcher-assisted bystander cardiopulmonary resuscitation (CPR). The other objective was to give an account of the frequency of agonal respiration in cardiac arrest calls and the caller's descriptions of breathing. METHODS: Prospective study evaluating 100 tape recordings of the EMD calls of emergency medical service (EMS)-provided advanced life support- (ALS) cases, of out-of-hospital cardiac arrest. RESULTS: The quality of EMD-performed interviews was highly commended in 63% of cases, but insufficient or unapproved in the remaining 37%. The caller's state of mind was not a major problem for co-operation. Among the 100 cases, 24 were suspected to be unconscious and in respiratory arrest. A further 38 cases were presented as unconscious with abnormal breathing. In only 14 cases dispatcher-assisted bystander CPR was offered by the EMD, and in 11 of these it was attempted, and completed in eight. Only four of the cases were unconscious patients with abnormal breathing. The incidence of suspected agonal breathing was estimated to be approximately 30% and the descriptions were; difficulty, poorly, gasping, wheezing, impaired, occasional breathing. CONCLUSIONS: Among suspected cardiac arrest cases, EMDs offer CPR instruction to only a small fraction of callers. A major obstacle was the presentation of agonal breathing. Patients with a combination of unconsciousness and agonal breathing should be offered dispatcher-assisted CPR instruction. This might improve survival in out-of hospital cardiac arrest.

Tape-recorded hypnosis instructions as adjuvant in the care of patients scheduled for third molar surgery.

UNLABELLED: As medical costs continue to escalate, there is willingness to consider the role played by nontraditional factors in health. We investigated the usefulness of tape-recorded hypnosis instruction on perioperative outcome in surgical patients in a prospective, randomized, and partially blinded study. Sixty patients scheduled for third molar surgery were studied. Patients were allocated to either an experimental group (E) or a control group (C). Group E received an audio tape to listen to daily for the immediate preoperative week, which guided the patients through a hypnotic induction and included suggestions on enhancement of perioperative well-being. Group C did not receive any tapes. The same surgeon administered local anesthesia and a standard regimen of sedation and performed the operation for all patients. The following variables were assessed 1 wk before surgery, immediately before and after surgery, and for 3 days after surgery by the indicated measurements: State anxiety by a Spielberger scale; nausea and pain by visual analog scales; number of tablets of the analgesics that were used; number of episodes of vomiting; and complications. In addition, the surgeon's assessment of ease of surgery was recorded. Two variables showed differences between the groups. First, Group C exhibited a mean increase of 11.7 points on the Spielberger scale from the screening to the presurgery period, while Group E showed only a mean increase of 5.5 points during the same period, P = 0.01. Second, the mean number of vomiting episodes was more in Group E, 1.3, than in Group C, 0.3, P = 0.02. In conclusion, anxiety was reduced before surgery by means of an audio tape containing hypnotic instructions; however, for no apparent reason, there was also an increase in the incidence of vomiting. IMPLICATIONS: We administered hypnosis instructions to patients before third molar surgery. Anxiety was reduced, but there was an increase in the incidence of vomiting. Although an easy and cost-effective method, the value of this approach remains to be established.

[Evaluation of Japanese school lunch cooks' work by foreign researchers: an attempt to promote an effective discussion by presenting a video tape record].

The aim of this study was to collect and examine foreign researchers' evaluations of Japanese school lunch cooks' workload, risk of musculoskeletal disorders, and some related issues by means of video tape discussion method at international conferences. The author reported work-related musculoskeletal disorders of Japanese school lunch cooks' at three international conferences. Together with the presentation a video tape recorded at one school kitchen during working hours was shown and the participants at the conferences were asked to evaluate the workload and risks of the Japanese school lunch cooks in the form of a questionnaire. Out of 151 participants from 21 countries at three conferences, 86 participants from 18 countries answered the questionnaire. The median of the values for Japanese school cooks' workload, derived by the Visual Analogue Scale method ranging from 0 (easy) to 10 (severe), was 8.5. Concerning the possibility of occurrence of musculoskeletal problems, 83% of the respondents pointed out that the occurrence of musculoskeletal disorders was certain, and 17% of them estimated that it was probable. Out of 18 countries from which participants came from, 12 countries were serving meals at school, and school lunch cooks in these 12 countries had similar occupational problems to those in Japan, such as musculoskeletal disorders, skin disorders and injuries, etc. The participants also pointed out that Japanese school lunch cooks were exposed to various problems, i.e., excessive workloads for women, and too few replacements of manual work by machinery. On the other hand, the cleanliness of the school kitchen, quality of meals, and conscientious cooking work were evaluated as very high. There were 36 researchers who asked for a copy of the video tape in order to use it in the education of industrial health personnel, medical students, and so on. These results showed the same tendency as Japanese researchers have found over the past 16 years. The video tape discussion method is proved to be useful in deepening mutual understanding at international conferences.

Tape recorder effects on jitter and shimmer extraction.

To test for possible contamination of acoustic analyses by record/reproduce systems, five sine waves of fixed frequency and amplitude were sampled directly by a computer and recorded simultaneously on four different tape formats (audio and FM reel-to-reel, audio cassette, and video cassette using pulse code modulation). Recordings were digitized on playback and with the direct samples analyzed for fundamental frequency, amplitude, jitter, and shimmer using a zero crossing interpolation scheme. Distortion introduced by any of the data acquisition systems is negligible when extracting average fundamental frequency or average amplitude. For jitter and shimmer estimation, direct sampling or the use of a video cassette recorder with pulse code modulation are clearly superior. FM recorders, although not quite as accurate, provide a satisfactory alternative to those methods. Audio reel-to-reel recordings are marginally adequate for jitter analysis whereas audio cassette recorders can introduce jitter and shimmer values that are greater than some reported values for normal talkers.
