    We are currently studying what kinds of problems occur when using the software with the kind of vocabulary used between doctors and patients. Using the voice recognition software "Dragon Naturally Speaking 2005" (DNS for short) from Scan Soft, we input the words from everyday medical usage into word processing software (Microsoft "Word"). Specifically, we created a model conversation between doctors and patients. Using DNS we dictated these documents into "Word". We studied the correctness of the conversion of the words and phrases and the types of conversion errors. Based on the number of errors we established 4 grades of difficulty in conversion and analyzed the causes of misconversion. Among total 9464 words the 341 (3.6%) words and phrases of misconversion were classified as follows: 77.3% into grade 2. easy by training, 8.5% into grade 3. difficult and 14.2% into grade 4. very difficult. The main causes of difficulty in conversion were failure to properly recognize pronunciation, faulty ranking of homophones or too many listed homophones and words not being registered in the dictionary, coined words. In order to use the voice recognition system in everyday practice, the creation of a language dictionary specifically for medical communication may be needed.

    It is desirable for team medicine that medical stuff such as doctor, or nurse and so on recognize their each role each other, and have an equal relationship. This concept is stated clearly as the aim of their medical practice for students. The statistical studies have been conducted on the recognition of the students about the role of nurse in students of medical, nurse, and management courses. As a result, it is found that the medical and nurse course students have a same recognition that they are on equal footing. On the other hand, the management course students have different opinions in several points since they are close to the point of view of patients. This means that there is a gap between the medical teams and patients. The students after experience of medical practice have a similar opinion on the role of nurse, and recognize the importance of making of cooperation with each other.

    Recently many midwifes are taking part into educations on the birth, baby and their lives. It is important to investigate what kind of recognisiton the midwifery course students have, especially on the education of the first menstruation. The aim of this paper is to clarify the relation between recognition to menstruation and the first menstruation education in midwifery course students. The search was done by the questionnaire for them. As the result, significant differences on the 8 contents of the education were seen among 2 groups, i.e., affirm tive group (N=22) and negative group (N=22).

    The previous study has been reported that the use of a room was visualized by using the number of the maximum and minimum date of the filtered ordinary noise with a passband of one octave. Because acoustic information is complementary to a blind spot, the measurement of the ordinary noise, respecting privacy, may provide an index of principal events in a common sight. Our present study has aimed at identifying whether the number of extrema could reflect the harmonics of noise originated in passersby, who were concurrently sensed by a pyroelectric infrared detector. While approximate seventy percent of 990 events per week related to infrared rays were reported by the conventional sound pressure level, which was hard to be normalized in a day, due to the large amplitude of an unexpected crashing sound, ninety percent of the events were detected by the number of extrema with a bandwidth of 2,560-5,120Hz, suggesting an unique security application in order to save time for the editing process of video archives.

    The purpose of our study is to evaluate the quality of synthesized speeches and noises by measuring the mismatch negativity (MMN) of the event-related potentials (ERPs). The proposed synthesis has required the superposition of six-channel sinusoidal interpolation between the extremal data of the filtered waveform, in which each passband had one octave, belonging to the total bandwidth of 80 to 5,120Hz. Subjects were presented with a repetitive stimulus of a male syllable /ki/, randomly replaced at a 14.3% probability by a synthesis. No MMN responses were observed in the task, suggesting that the extremal data played a key role in the synthesis of the phonetic equivalence of the acoustic structure. When the discontinuous or distorted interpolation was employed for the syllable and mechanical noise of a door slamming as deviant stimuli, the degraded syllable merely elicited MMN. The result has interpreted as the evidence of the superiority of speech perception to noise.

    The method of information acquisition was diversified by the advancement of the information technology. The Web technological improvement is remarkable, and a lot of information is being offered through the website. In order to do this, the chance for not only young people but also the elderly and dichromatic vision have to use the website to exchange and acquire information. It is necessary to maintain the Web accessibility so that all the people may safely use the website. However, data concerning the visual feature that can he used to make Web contents is not clear. In this report, the visibility of the elderly and dichromatic vision was measured using the simulation filters, and the relation between the visibility and the color difference ΔE_<00> was evaluated. As the results, the visibility has improved, when ΔE_<00> between characters and a background was increased. In particular, it was judged that the visibility was high by all groups, if ΔE_<00> is more than 42 in this experiment. Moreover, it was shown that because the characters color that did not include G value of RGB value was judged the high visibility. Therefore, it has to be very careful when the character color including G value is used.

    "Comfort" in shampooing is a largely subjective aspect for subjects, and it has been used as a means of evaluation after care has been provided, or it has been judged from the measured value of the hardness of the trapezius muscle. On the other hand, considering supportive techniques for providing comfort, an evaluation index of "comfort" is required as an index that can be used to instantly modify care while developing life-supporting techniques and leading subjects toward greater levels of "comfort." Therefore, this study is aimed at creating an index of "comfort" that can be instantly evaluated according to the senses of the operators while shampooing, without using a measuring instrument. The subjects, who were healthy students ranging from 18 to 21 years of age, were shampooed in a seated position in a chair. When being shampooed, the head was secured by inserting a towel or a neck protecting pad, or placing a headrest at the back of the head, and the difference in muscle hardness of the sternocleidomastoid muscle was thus examined. The shampooing was performed by the same person in order to provide uniformity of the procedure. The value of hardness of the sternocleidomastoid muscle did not change before and after shampooing in any group, but the muscle hardness value during shampooing (median value) was 44 in the group that used a headrest, 49 in the group that used a towel, and 52 in the group that used a neck protecting pad. The muscle hardness value during shampooing was significantly lower for the group that used a stool than for the group that used a neck protecting pad. When studied via a questionnaire method, a feeling of insecurity of the head was felt less in the group that used a headrest than in the group that used a neck-protecting pad. When the hardness of pillows used in nursing practice is measured on a hardness scale, the hardness value of pushing the middle of a small pillow can be represented as 49 or less, which is "feels soft," while that of pushing the middle of a medium-sized pillow can be scored as 50 to 54, which is "somewhat hard, like being stretched," and that of pushing the middle of a large pillow is shown by a value of 55 or higher, which is expressed as "feels hard." We propose the use of these expressions as a hardness index for the sternocleidomastoid muscle. From the results of this study, it is believed that when the sternocleidomastoid muscle "feels softer" than that of pushing the middle of a small pillow, then there is a sense of stability in the head. However, when it "feels hard, like being stretched" as when pushing the middle of a medium-sized pillow, then the sense of stability of the head is not obtained, and "comfort" may also be lost.

    A functional magnetic resonance imaging study on visuo-spatial working memory task using sinusoidal luminance grating inferred to have little influence on verbal working memory was presented. Seven right-handed healthy male participants wearing a head mount display were scanned while performing two 2-back tasks using the different spatial frequency stimuli. As results, the accuracy of the task using low spatial frequency stimuli was significantly-higher than that of the task using high spatial frequency stimuli. Moreover, both tasks activated the neural network between the prefrontal cortex and the parietal cortex. The activated areas on the right hemisphere were larger than those on left hemisphere. The intensity level of the frontal cortex activation was also asymmetric. The high spatial frequency task activated the right hemisphere higher than the left hemisphere. On the contrary, the low spatial frequency task activated the left hemisphere higher than the other one. Moreover, the activation in the ventrolateral region of left prefrontal cortex during the low spatial frequency task was salient. The activation was found to be caused by the verbalization changing the low spatial stimuli into the numbers.

    A survey was performed on 276 nursing students in April 2004 in order to establish an educational and supporting method on risk management. The self-completed questionnaire evaluated nursing students' memory of their past history of infection or vaccination of measles, rubella, mumps and chickenpox. When analyzing the past history of infection, our results indicated that the memory rate of first-year students was higher than any other year students in each infection. The memory rate was high in chickenpox (90.8%) and mumps (93.3%), whereas the prevalence rate of chickenpox (88.4%) was higher than mumps (50.4%). When analyzing the vaccination of unaffected students, the memory rate in measles and rubella (60-70%) was greater than the rate in mumps and chickenpox (approximately 50%). As a result of this study, appropriate measures should be taken to immunize students who have not acquired the antibodies against childhood viral infections until the age of adolescent.

    The prediction accuracy of QRS complex is not good in predictions of electrocardiogram used Volterra functional series yet. The cause is not to be able to predict enough, even if Volterra functional series is used because production mechanism for QRS complex contains strong nonlinearity. Therefore, means for prediction using an input delay neuron network which nonlinear prediction capability is higher was proposed. However, it is not sufficient on QRS complex though the prediction accuracy is improved overall. Aim of this study is further to improve on prediction accuracy for electrocardiogram using a 2^<nd>-order Volterra neuron network which processing performance to time series signal with strong nonlinearity is high. Then, nonlinear prediction capabilities for electrocardiogram by an input delay neuron network and a 2^<nd>-order Volterra neuron network are evaluated. As a result, prediction accuracy of the 2^<nd>-order Volterra neuron network is shown the remarkable improvement of 66.7% than the input delay neuron network on the average about root mean square error.
