The purpose of this study was to analysis children's engagement behavior and teachers' linguistic behavior by type of group activity in kindergarten. The subjects were 45 children and 2 teachers of 5 years' class in 2 kindergarten. The data were collected by 16 times observation in general classrooms for 4 weeks to explore the children's engagement behavior and teachers' linguistic behavior. The results of this study are as follows: Firstly, the large group and structural activity from initiated teacher's plan. Secondly, children's watching and listening behavior was most frequently shown in academic large group activity. And children's active engagement behavior was most frequently shown in free play of peer group. Finally teachers explained and directed frequently in academic large group activity. And teacher praise and permission was frequently shown in free play of small group teacher-child interaction. Consequently, it is important to recognize the relationships between the activity type and children's engagement behavior in organized daily program for early child education.

Purpose: This study compared the total antioxidant status (TAS) and superoxide dismutase (SOD) activity in the saliva of periodontally compromised patients before and after scaling and root planing (SRP) to assess their diagnostic utility. Methods: Severe chronic periodontitis patient (test group) and subjects with no attachment loss, sites showing a 3 mm or more probing depth and a sulcus bleeding index < 10% (control group) were enrolled in this study. Saliva sampling and clinical examination were performed at one week, one month and 3 months after SRP. The TAS and SOD activity in each patient's saliva was measured for the comparative analysis between the groups. Results: In the test group, the TAS decreased directly after SRP. With time, it increased slightly and was relatively unchanged compared to the baseline. In the control group, the TAS also decreased immediately after SRP but increased gradually with time until 3 months. The SOD activity in the test and control subjects decreased immediately after SRP until 1 month. At 3 months, the SOD activity had increased. Both groups had a similar profile of SOD activity. However, the SOD activity of the control group was significantly higher than that of the test group at each point in time (P < 0.05). Conclusions: There was a significant difference in the total salivary antioxidant level between the periodontitis and healthy or gingivitis (control) group during the experiment period. The total antioxidant level in the saliva was higher in the patients with severe chronic periodontitis than the healthy or gingivitis control before SRP. The SOD activity of the periodontitis patients was lower than the control at each time point. These findings conclusively reveal the possible use of saliva as a diagnostic tool for periodontal health.

Participants in this study of the effect of story making activity on the language expression and creativity of young children were all forty 5-year-old children in a child-care facility. The experimental group read the fantasy picture book and engaged in story making activity; the control group read the same fantasy picture books the experimental group but didn't have any story making activity. Experimental treatments were given twice a week for 6 weeks. Data were analyzed by MANCOVA using scores of the pre-test as covariance. Differences were found between experimental and control groups in language expression and creativity showing that story making activity using the fantasy picture book was more effective than just reading without story making activity.

This study was undertaken to identify the degree of burden and depression according to level of self-care activity and variables to which affect that in family caregivers of patients with stroke. The data were collected from October 23th to November 20th, 1995 The subjects in this study were 80 caregivers, that is, one family member and 80 patients with stroke who were hospitalized in one oriental medicine hospital in D city. The questionnaires consisted of questions regarding burden(13 items, 6 point scale), depression(20 items, 4 point scale), and self-care activity(15 items, 5 point sacle) Data were analyzed using percentages, means, t-test and ANOVA with the SAS program. The results of this study are as follows: 1) The mean score for client's self-care activity was 2.58. The highest score of the self-care activity item was 'returning'(M=3.604), and the lowest score of the self-care activity item was 'shower or tubbathing'(M=1.925). 2) the degrees of self-care activity according to the general characteristics of patients were tested. It was significantly different by sex(P<0.01), occupation(P<0.05), and relationships with patients(P<0.05). That is, the degree of self-care activity was higher in men than that of women, and caregiver with job than caregiver without that. In the case that caregiver was a patient's spouse, the degree of self-care activity was higher than other case. 3) The score for family caregiver's burden was higher than the mid level for the 13 items and caregiver's depression was relatively low. 4) According to the degree of self-care activity, the group was divided to 3, that is, A( 15-33), B(34-56), and C(57-75). The score of total burden was the highest in group A(M=55.257) and the lowest in group C(M=51.928), but there were no statistically significant differences between groups. The score of objective burden was the highest in group A(M=30.400), and the lowest in group C(M=25.214), and there were statistically significant differences between groups. The score of subjective burden was the highest in group B(M=26.000) and the lowest in group A(M=24.783), but there were no statistically significant differences between groups. The degree of depression was the highest in group A(M=44.750) and the lowest in group C(M=40.751), but there were no statistically significant differences between groups.

This study explores the types of daily routines in child care centers based on the time planned for indoor free choice activities, outdoor activities, group activities and nap/rest. The daily routine plans of 63 classes of 0 to 2-year-olds and 51 classes of 3 to 5-year-olds were cluster analyzed. Also, openness and closeness of child care programs as well as the most participated indoor/outdoor activities were examined using questionnaires developed for teachers. The results were as follows: First, teachers planned the most time for free play choice activity and comparatively less time for outdoor play during the day. Time for rest and naps were planned more for 0-2 year-olds whereas group activities were planned more for the 3-5 year-olds. Second, 3 daily routine types were found in the daily plans of child care centers, such as "Low-Activity Oriented," "Free Choice Activity Oriented" and "Group Activity Oriented" in 0 to 2-year-old classes and 3 to 5-year-old classes. Also, "Group Activity Oriented" type in 0 to 2-year-old classes showed more "closed" child care programs than the "Free Choice Activity Oriented" type. However, no difference was shown among the 3 types of daily routines in the openness and closeness of 3 to 5-year-old child care programs. Finally, all children, regardless of the types of daily routine, participated most in block activity and role play indoors and fixed-play equipment, sand play and free play outdoors.

It has been believed that antioxidant enzymes such as CuZn- and Mn-superoxide dismutase and catalase protect the tissue from damage resulting from the oxygen derived free radicals($O_2\;^-$, $H_2O_2$ and OH ). The purpose of this study was to investigate the relationship between activity of antioxidant enzymes including CuZn- and Mn- superoxide dismutase and catalase and inflammatory periodontal disease and periodontal parameters. For this study, the patients were classified into normal, gingivitis, adult periodontitis and rapidly progressive periodontitis, and then their papillary bleeding index(PBI) and probing depth were checked. Gingival tissues were surgically obtained from the patients during periodontal surgery, extraction, and clinical crown lengthening procedure. The activity of CuZn- and Mn- superoxide dismutase and catalase in the gingival tissues was measured by using UV-spectrophotometer by the same methods as Crapo et al. And Aebi did, respectively. The results were as follows : 1. CuZn- and Mn- and total-superoxide dismutase activity were significantly low in rapidly progressive periodontitis group in comparison to normal group (P<0.05). 2. In comparison of the antioxidant enzyme activity according to papillary bleeding index group(PBI), Mn-superoxide dismutase activity only was significantly lower in PBI 2, 3, and 4 groups than PBI 0 group(P<0.05). 3. Superoxide dismutase activity failed to show any significant difference according to probing depth. But significant]y high catalase activity was shown in deep pocket group (${\ge}7mm$)(P<0.05). In conclusion, these results suggest that the activity of Mn-superoxide dismutase among the antioxidant enzymes may reflect the inflammatory status of gingival tissue and that the decreased activity of superoxide dismutase may be one of responsibe factors for progression of rapidly progressive periodontitis.

The action of serotonin on the sodium plus potassium activated ATPase activity in the rabbit red cell membrane has been investigated. The experiments were also designed to determine the mechanism of action of serotonin on the ATPase activity. The following results were obtained. 1) The NaK ATPase activity of rabbit red cell ghosts is stimulated by low concentration of serotonin but inhibited by higher concentration, and the concentration of serotonin for maximal activity is about 2mM. The pH optimum for the serotonin sensitive component is 8.0. 2) The activating effect of serotonin on the ATPase, with a given concentration of sodium in the medium, is increased by raising the potassium concentration but the ratio of activity is decreased. 3) The activating effect of serotonin on the ATPase, with a given concentration of potassium in the medium, is increased by raising the sodium concentration but the ratio of activity is decreased. 4) The ATPase activity is increased by small amounts of calcium but inhibited by larger amounts and the ratio of activity by serotonin is decreased by small amounts of calcium but increased by larger amounts. 5) The action of serotonin on the ATPase activity was not related to the amino group of lysine, the hydroxyl group of threonine, the carboxyl group of aspartic acid, or the imidazole group of histidine. 6) The action of serotonin on the ATPase activity is due to sulfhydryl group of the enzyme of NaK ATPase.

Purpose: This study attempts to determine the effects of water-based exercise performed on stroke patients in their muscle activity of lower extremity and gait ability tests. Methods: The subjects were 20 stroke patients, who were randomly divided into a water-based exercise group and a land-based exercise group, each including 10 patients. Both exercises were performed 3 days per week, for 40 minutes a day, for a period of eight weeks. Results: The water-based exercise group showed a greater increase in muscle activity of lower extremity compared to the land-based exercise group. The water-based exercise group showed a greater increase in gait ability than the land-based group, showing a significant difference and better efficiency of water-based exercise when compared to land-based exercise. Conclusion: From the result of this study, we found that water-based exercises are more effective in improving muscle activity of lower extremity and gait ability. The patient is considered to be used by itself to involve the treatment and the risk of falling from the lowered state into the treatment method for the intensive treatment of stroke patients to be useful in improving the strength and ability to walk.

Subway environments such as crowd, passenger's gab, or subway-generated mechanical noise may become a potential stressor. The present study was sought to determine whether subway noise with or without mental activity affects cerebral hemodynamics and sympathetic system. Fifty-four healthy volunteers were divided group I which underwent subway noise (n=24) and group II which underwent a combined mental activity (mental arithmetic) with subway noise (n=30). Sympathetic factors such as heart rate (HR), blood pressure (BP) and heart rate-systolic pressure product (RPP), and mean blood flow velocity in the middle cerebral artery (MCAV) were measured before (baseline), during and after the noise-exposure. Systolic and diastolic blood pressure, HR and RPP significantly increased in group II (P<0.05) but not in group I during the noise-exposure. Peak-MCAV, diastolic-MCAV and mean-MCAV in the both groups were elevated during the noise-exposure (P<0.05) and the increased ratios in group II were greater than those in group I. These results suggest that a combined mental activity with subway noise may be a stressor which affects cerebral hemodynamics and sympathetic system.
