The purpose of this survey is to grasp the special school therapeutic education teachers, stress degrees in the real educational fields, and to campare the different stress degrees by the teaching responsibilities, by set by age, by the careers of special teaching profession, by his or her assiduity by the academic careers and teacher qualification, and by the reasons of stress. To perform this survey, the writer analyzed the answer sheets of the questionnairs returned by 85 special school therapeutic education teachers all over the country. The results of the analysis are as follows: First, the mean value of stress by the whole teachers was shown as endurable, and there was no difference among stress towels by the teaching responsibilities. As for the ratio of teachers confronted with the dangerous level of stress. the teachers taking charge of feebleminded school teachers the highest ratio, and those charging of deaf & dumb school teachers, the lowest. Second, the comparison by age didn't result in any difference, but in the relation of age to the handicap division there appeared meaningful differences. That is in the case of the therapeutic education theachers charging of crippled school, it revealed that the older they were, the more stress they suffered. In the case of the teachers charging of visually deaf & dumb school the tendency was opposite. The comparison by the special teaching profession careers, there showed no difference in the stress degree. The high or low academic careers didn't make any influence on the therapeutic education teachers stress degree. Third, The revealed on the highest stress degress, because reasons of relation the student's parents with students behavior.

The purpose of this study was to identify critical parameters of a putting performance using jerk cost function. Jerk is the time rate of change of acceleration and it has been suggested that a skilled performance is characterized by decreased jerk magnitude. Four elite golfers($handicap{\leq}2$) and 4 novice golfers participated in this study for the comparison. The 3D kinematic data were collected for each subject performing 5 trials of putts for each of these distances (random order): 1m, 3m, 5m The putting stroke was divided into 3 phases such as back swing. down swing and follow-through. In this study, it was assumed that there exist smoothness difference between elite and novice golfers during putting. The distance and jerk-cost function of Putting stroke for each phase were analyzed Results showed that there was a significant difference in jerk cost function at putter toe (at media-lateral direction) and at the center of mass between two groups by increasing putting distance. From these it could be concluded that jerk can be used as a kinematic parameter for distinguishing elite and novice golfers.

Intentional draw and fade shots could be good weapons for lowering golf score. But how to make such shots? To investigate deterministic variables generating different projectile paths of shots in square stance was the purpose of this study. Ten right-handed male collegiate athletes, showing 1.3 of averaged handicap, participated in this study. They were asked to intentionally perform three different shots such as the straight shot(control condition), draw shot, and fade shot. Swing path, pelvis rotation angle, thorax rotation angle and left forearm supination angle were determined for dependent variables on impact event at each trial. For statistical analysis one-way repeated measures ANOVA were used. The results showed that swing path was one of main factor making differences among three kind of shots. Straight shot vs. Draw shot, Straight shot vs. Fade shot and Draw shot vs. Fade shot showed differences on swing path. And left forearm supination angle revealed significant difference between draw shot and fade shot, showing a significant larger angle of draw shot than fade shot. No other significant difference was detected for the other variables. We found that the shot characteristics were influenced primarily by swing path and left forearm supination angle.

Many previous studies based on respiratory characteristics of Idiopathic Parkinson's Diseases (IPD) patients have not controlled related factors appropriately. Accordingly, these studies produced discordant results. Furthermore, there is currently a lack of studies that can provide precise explanations on the characteristics of respiration and phonation. This study included a total of 40 subjects: 20 mixed gender de novo IPD patients ranging in age from 50 to 80 (Hoehn & Yahr stage 1~3), and 20 normal subjects with similar matches for age and gender. All participants were controlled based on their gender, age, height, weight, vocal fold function, cognitive abilities, and depression factors. K-MMSE (Korean-Mini Mental State Examination), nVHI-10 (new Voice Handicap Index), and KGDS (Korean Form of Geriatric Depression Scale) were evaluated to select this study subjects. In order to compare respiratory functions between the two groups, FVC, FEV1, and FEV1/FVC were measured using microQuark, a PC-based spirometer. CSL was used by measure MPT and PAS was used to measure MFR. To investigate the characteristics of phonation ability, CSL was used to measure jitter and shimmer, while PAS was used to measure Psub. In order to compare the respiratory function averages and phonation ability between the two groups, statistical analysis was conducted using SPSS (version 12.0). The results of this study showed that most de novo IPD patients were included in the normal average range of respiratory and phonatory ability. But the respiratory and phonatory ability of de novo IPD patients showed lower tendency as compared with the normal group. When the average of respiratory and phonatory ability among the gender was compared, the difference of males was greater than the difference of females.

Mothers with cerebral palsy children have much stress that is related to the care of children with cerebral palsy and to other household duties, and this state of the mother has an effect on the cerebral palsy child and on other household member. Mothers in such stressful situations use various coping patterns. The purpose of this study was as follows : to develop instruments that can be used for measuring the stress and coping patterns of mothers with cerebral palsy children, and to test a hypothetical model on the relationship between the mother's stress, her coping patterns and the variable affecting the stress and coping patterns. The results of this study can be summarized as follows : 1. The stress scale was composed of 44 items and Cronbach's α was .94, and the coping pattern scale was composed of 19 items and Cronbach's α was. 80. The mean score of stress scale was 136.12 out of a total of 220, and the mean score of the coping scale was 72.87 in a total of 95. 2. In test of the hypothetical model, it was found that extra-care demand, the support of the husband, the degree of handicap, health status and self-esteem had statistically significant influence on the mother's stress(r=.285,-.262,-.133, -.126). And the support of the husband, formal support, informal support, and economic status were found to have statitically significant influence on the mother's coping patterns (r=.412, .178, 178, .138).

Objectives : The purpose of this study was to investigate the relationship between the oral health status of elderly people and their oral health-related quality of life. Methods : The subjects were the elderly people over 65 years old in Busan. A total of 479 elderly people participated in the study from general hospital, two research institutes, eight dental clinics, six welfare institutions, sixteen senior centers, and three nursing homes. The oral health impact profile-14 (OHIP-14) was used in the routine dental checkups of the elderly people. Results : Those who had no oral symptoms had a better oral health-related quality of life. Among the subfactors of the OHIP-14, significant differences were shown in functional limitation(p=0.001), physical pain(p<0.001), emotional discomfort(p<0.001), physical disability(p=0.001), emotional disability (p=0.001), social disability(p=0.005), physical handicap(p=0.003) and total OHIP-14(p<0.001). Those who had 18 sound teeth(natural teeth) or more had a better oral health-related quality of life. Among the subfactors of the OHIP-14, significant differences were shown in functional limitation(p<0.001), physical pain(p=0.007), emotional discomfort(p=0.019), physical disability(p=0.018), Emotional disability(p=.032) and total OHIP-14 (p=0.006). Conclusions : The results revealed a close relationship between oral health status and oral health-related quality of life. The number of sound teeth(natural teeth) and frequency of toothbrushing had a more positive influence. Therefore oral health programs for the elderly people can preserve remaining teeth. Toothbrushing is the best way to improve the quality of life in the elderly people.

The objective of this study was to analyze the difference in kinematic variables for successful and unsuccessful golf putting strokes. The study population included 8 male secondary school golf players who had played golf for over 3 years and whose handicap was 4 or lower. A hole was made on a 5-m-long artificial flat mat for practice, and an environment similar to that of a real green was created. The participants' motions were analyzed through 3D image analysis, and the difference in kinematic variables for successful and unsuccessful putting strokes in the same direction was determined. Data analysis revealed the following findings: The time spent for a segment of putting was the greatest for the backswing segment for both successful and unsuccessful strokes. During address and impact, the both changed to a larger extent. For successful putting strokes, the change in the elbow angle during the downswing was greater for the right elbow than for the left elbow. For both successful and unsuccessful putting strokes, the left shoulder angle increased during the segment from address to the turning point and decreased during the segment from the turning point to impact. In contrast, the right shoulder angle significantly differed between successful and unsuccessful putting strokes only during address. During successful and unsuccessful motions, the swing was executed with the moving displacement of the X-axis of the club head maintained almost constant along a straight light without back and forth movement. In the backswing segment, moving displacement of the Y- and Z-axes was greater in successful strokes than in unsuccessful strokes; however, this difference was very small for the Y-axis. The velocity of the club head for successful and unsuccessful motions significantly differed during address and at the turning point. The highest velocity of the ball was greater for successful than for unsuccessful putting strokes.
