In this study electrical impedance plethysmograph was developed and each ten digital blood flow was measured for eight nomal males and a patient tvith digital arterial reconstruction surgery. Blood flow of the digit with surgery was approximately fourty percent compared to that of the other normal digit. For the normal subjects, right - handed subjects generally have larger blood flow in right fingers than that in left fingers while it was reverse for the left - handed subjects. The relative average magnitude of the digltal blood flow Is the third, first, second, fourth, and fifth digit in descending order for the left and rich hand, respectively. Blood flow of the fifth digit for all subjec!s except one was the smallest among the five digits.

This study attempted to determine the effects of a context-based drawing task on the language expression of a severe Wernicke's and Broca's aphasic. The subjects in this study showed a poor auditory comprehension and naming performance. They also showed paraphasia and perseveration. This study focused on improving language expression by a drawing task based on conversation at hand. Ten target words were chosen which were easily drawnable and familiar to the subjects. The results showed that the context-based drawing task was effective on improving the subjects' confrontation naming ability and expressive language ability in terms of explanation of sentences. In addition, the Broca's aphasic showed improved naming ability when the contextual cues were given and he was supposed to spontaneously name words.

Backsulgies containing various levels of guar gum(0g, 2.5g or 5g) were ingested by ten healthy male subjects after 12-h fast. Guar backsulgies was given a time in a week a time in a week for 3 weeks with 75g glucose. The Sensory qualities of backsulgies containing guar gum powder of different levels(0g, 2.5, 5g) were also evaluated using a hedonic scoring technique. On each test day 4ml samples of venous blood were taken from the fasted subjects. Further 4ml post-prandial blood samples were taken from the subjects 30, 60, 90 and 120min after guar backsulgies had commenced. Result were as follows: Plasma glucose and insulin levels were not sifnificantly reduced according to guar gum levels in backsulgies. But plasma glucose and insulin levels of the case which ingested 5g guar backsulgies tended to be lower than those of the case which ingested 0g or 2.5g guar backsulgies. Therefore it is recommended that 5g guar backsulgies is most effective snack of diabetics. KEY WORDS: guar backsulgies plasma glucose, plasma insulin, snack.

This study examined concept development in children in terms of sound propagation. The subjects consisted of 240 five-, seven-, and ten-year-old children from three kindergartens and two primary schools respectively. The instrument used for the purposes of this study was the examination instrument on sound as developed by the SPACE Project in the UK. The concepts related to sound were classified into five stages including : no recognition, egocentric concept, initial mental models, synthetic mental models, and scientific mental models. The results revealed the existence of significant differences in terms of the types of concept that children were aware of, according to age and context. Most five-, seven-, and ten-year-old children revealed egocentric concepts related to every sounds, drum, rubber band context, however, most five-, seven-, and ten-year-old children revealed their recognition of the synthetic models of sound propagation when using the string telephone context. These results have implications for the contents of science education for children when it comes to the development of concepts related to sound propagation.

PURPOSE: The purpose of this study was to investigate the effects of ten minutes of manual passive exercise performed by physical therapists on autonomic nervous system. METHODS: Thirty-five healthy adults, both male and female, were chosen as subjects for this study. The autonomic nervous system was measured by heart rate variability (HRV),before and after passive exercise using the following measurements: mean heart rate (mean HRT), low frequency (LF) and high frequency (HF) components, the LF/HF ratio, root mean square of the successive differences (RMSSD), and the HRV index. The exercise was performed on the subjects by a physical therapist with seven years of experience specializing in the nervous system. The exercise was conducted at the mid-range of motion on the upper and lower limbs of the subjects for two minutes and thirty seconds and for a total of ten minutes. RESULTS: There was a significant increase in the LF component. The mean HRT and the LF/HF ratio both increased, but these increases were not significant. The HF component, RMSSD, and HRV index all decreased, but these decreases were not significant. CONCLUSION: In conclusion, mid-range manual passive exercise does not induce stress on the autonomic nervous system. It can safely be performed by a physical therapist.

The purpose of this study was to determine the effects of music therapy and ball exercise on women experiencing menstrual discomforts, thereby identifying the validity of these methods as interventions against menstrual discomforts, with a particular goal of presenting basic data for clinical use. Twenty university students in their 20s were assigned to two therapy groups in a sequence via simple random sampling; ten subjects attended a ball exercise combined with music therapy group and the other ten subjects attended a music therapy group. Ball exercises were conducted 3 times per week for a total of 12 times, starting from 3 weeks before the expected first day of the menstrual period and ending on the last day of the menstrual period. Similarly, the subjects participated in music therapy by listening to music for 35 minutes per session and 3 sessions per week, starting from 3 weeks before the expected first day of the menstrual period and ending on the last day of the menstrual period. Five out of six categories of menstrual discomforts were significantly decreased in both music therapy and ball exercise, the exception being changes in the autonomic nervous system, while those in the music therapy group showed a significant difference only in the category of behavioral changes. The results of the present study demonstrate that the ball exercise combined with music therapy more effective in improving menstrual discomforts than the music therapy group.

The purpose of this study was to determine whether the convergence pulmonary function of the 20s men of mild intellectual disabilities with obesity to tredmill exercise. Ten subjects of mild intellectual disabilities with obesity(experimentals) and ten contrary subjects(controls) were participated in the experiment. experimental group conducted treadmill gait training and control group conducted automed exercise. Subjects were assessed for their respiratory function by using Fit mate. The result of the experiments showed high pulmonary function than the controls. Thus, it suggests that the respiratory functional data of 20s men of mild intellectual disabilities with obesity can be used as a various respiratory one for the exercise programs in the area.

Purpose： The purpose of this study was to investigate the actual conditions of obesity, and the factors related to children's obesity. Method： The subjects were 568 students (5th, 6th grades) of ten elementary schools in a small city of about 350,000. Subjects self-reported after being instructed by researchers to identify health habits and attitudes toward obesity. The Rohrer index was calculated by using annual physical examinations preformed by the schools. Result： 17.5％ of the subjects were under weight, 22.2％ were overweight, and 60.3％ were normal. In girls, the under weight group was much larger, in boys the overweight group was larger. 46.2％ of overweight children had a familial tendency to obesity. 60.6％ of boys and 60％ of girls were on a diet in order to improve their looks or to prevent ridicule from mends. On average, one-third of the subjects misunderstood their own weight level. Subjects spent 3-4hours on weekdays, and over 6hours on the weekend watching TV or using personal computers. The overweight group enjoyed eating meat, fish, beans and vegetables, while the normal group tended to prefer fruit. Conclusion： Health education programs which guide elementary school students to form better health habits, more accurate perceptions of their own body weight, and better attitudes toward obesity and which make students aware of the importance of exercise, a healthy diet, and reducing time spent in front of TVs and computers may help them to keep at their appropriate weight.

Objective: The purpose of this study was to identify the effect of reduced plantar cutaneous sensation on gait kinematics during walking with and without CAI. Method: A total of 20 subjects involved in this study and ten healthy subjects and 10 CAI subjects participated underwent ice-immersion of the plantar aspect of the feet before walking test in this study. The gait kinematics were measured before and after ice-immersion. Results: We observed a before ice-immersion on plantar cutaneous sensation, CAI subject were found to reduced ankle dorsiflexion, knee external rotation, hip adduction, and internal rotation compared to control subject. After ice-immersion, CAI subjects were found to reduce knee external rotation, hip adduction. However, no significant ankle joint kinematics. Conclusion: While walking, gait pattern differences were perceived between groups with and without plantar cutaneous sensation. The results of the study may explain the abductions in the hip angle movements in CAI patients at initial contact compared to healthy subjects in the control group when plantar cutaneous sensation was reduced. A change in proximal joint kinematics may be a conservative strategy to promote normal gait patterns in CAI patients.

The purpose of the present study was to evaluate the nutritional status of the Korean population and its relationship with the age, sex, economic status and geographic characteristics. Taking in consideration the geographic location and socioeconomic states, ten regions out of the twenty-four regions where the Ministry of Health and Social Affairs had executed a programme (National Nutrition Survey) on evaluation of the community nutritional status were selected. Hemoglobin concentration hematocrit, and mean corpuscular hemoglobin concentration were tested from a total of 906 subjects in a month of November, 1979. The results of this study suggest that the anemia prevalences of young children in Seoul and rural areas were remarkedly decreased during last ten years, but the prevalence of low income group in provincial cities are still high and particularly in 7-l4yr. and female adult group.
