This study was conducted to examine changes in the muscle activity of the triceps surae, specifically the gastrocnemius and the soleus, depending on the angle of the knee joint during the manual muscle test (MMT) of the plantar flexion of the ankle. The muscle activity of the medial and lateral heads of the gastrocnemius was statistically significantly reduced when the angle of the knee joint was $15^{\circ}$, $30^{\circ}$, and $45^{\circ}$ compared to when the angle was $0^{\circ}$. However, there was no statistically significant difference in muscle activity at the angles of $15^{\circ}$ and $30^{\circ}$ or $45^{\circ}$. There was no statistically significant difference in the muscle activity of the soleus depending on the angle of the knee joint. The ratio of the muscle activity of the soleus to that of the triceps surae showed a statistically significant increase when the angle was $15^{\circ}$, $30^{\circ}$ and $45^{\circ}$ compared to when the angle was $0^{\circ}$. However, there was no statistically significant difference in muscle activity at the angles of $15^{\circ}$ and $30^{\circ}$ or $45^{\circ}$. When the angle of the knee joint was $15^{\circ}$ or higher during the test of the isolated soleus, the muscle activity of the gastrocnemius was reduced. These results indicate that the angle is suitable for the test of the isolated soleus, but there was no statistically significant difference in the muscle activity of the gastrocnemius when the angle was higher than $15^{\circ}$. Therefore, it can be concluded that the most suitable angle of the knee joint for the isolated MMT test of the soleus is $15^{\circ}$.

Background: This study investigated the effect of robot-assisted arm training on muscle activity of arm and weight bearing in stroke patients. Methods: The study subjects were selected 20 stroke patients who met the selection criteria. 10 people in the robot-assisted arm training group and 10 people in the task-oriented arm training group were randomly assigned. The experimental group performed robot-assisted arm training, and the control group performed task-oriented arm training for 6 weeks, 5 days a week, 30 minutes a day. The measurement tools included surface electromyography and smart insole system. Data were analyzed using independent sample t-test and the paired sample t-test. Results: Comparing the muscle activity of arm within the group, the experimental group and the control group showed significant differences in muscle activity in the biceps brachii, triceps brachii, anterior deltoid, upper trapezius, middle trapezius, and lower trapezius. Comparing the muscle activity of arms between the groups, the experimental group showed significant difference in all muscle activity of arm compared to the control group. Comparing the weight bearing within the groups, the experimental group showed significant difference in the affected side and non-affected side weight bearings and there were significant differences in anterior and posterior weight bearing. The control group showed significant difference only in the non-affected side weight bearing. Comparing the weight bearings between groups, the experimental group showed significant difference in the affected side and non-affected side weight bearings compared to the control group. Conclusion: This study confirmed that robot-assisted arm training applied to stroke patients for 6 weeks significantly improved muscle activity of arm and weight bearing. Based on these results, it is considered that robot-assisted arm training can be a useful treatment in clinical practice to improve the kinematic variables in chronic stroke patients.

The need of oriental nursing role is recently increasing. The implication of this trend is enormous not only for the need of independent of independent oriental nursing intervention. Hence, this study was designed to describe the characteristics of oriental nursing activity and identify the meaning of nursing activity in oriental hospital. A total of 24 nurses were selected by convenience sampling from eight units at one oriental hospital. A total of 168 data were collected using minute-by-minute recording during nurse s work shift. The data were analyzed using nova and scheffe method as post-hoc test The results of this study are as follows; 1. the category of nursing activity in oriental hospital 74.4% of nursing activity was the patient-oriented nursing care. The nursing activity included others (18.28%), the function-oriented nursing care (7.07%), and staff-oriented care (0.2%). 29.1 % of the patient-oriented nursing care was the direct care, and 24. 5 % of the patient-oriented nursing care was the indirect care. There was a lack of patient education and the communication patient. 2. Nursing activity in oriental hospital by characteristics 1) Nursing activity by unit For patient-oriented nursing care, there was a statistically significant difference among 8 units. In the critical care unit, the patient-oriented nursing care was mostly performed. For function-oriented nursing care, there was statistically significant difference among 8 units. In the physical therapy unit, the function-oriented nursing care was mostly performed. 2) Nursing activity in oriental hospital For all kinds of nursing activity, there was a statistically significant difference between shifts. In night shift patient-oriented nursing care, function-oriented nursing care, and other kinds of nursing care was mostly performed. Patient-oriented nursing care included indirect care, treatment set management, and the breaktime. In day shift, staff-oriented nursing care was performed. 3) Nursing activity in oriental hospital For all kinds of nursing activity, there was not a statistically significant difference by day. The day has not impact on nursing activity. 3. the meaning of activity in oriental hospital The results of this study show that the patient-oriented care was vital check, input! output check, medication, bedsore prevention, nasogastric feeding, oral care, catheterization care, perinatal care, nursing care associated with acupuncture and moxacautery, observation (fever, sweating), heat and cold application communication with patent and family, and patient room management In conclusion, two issues associated with the findings of the research appeated to be involved in the difficulty of nursing activity in hospital. The first issue was the nursing care in oriental hospital provided by nurses who have a limited understading of the principles of oriental medicine. The second issue was the deficiency of systematic guideling for oriental nursing activity. The findings suggest the need to develop the systematic guideline for oriental nursing activity. The need of continuing education for nurses who work in the oriental hospital, and the need of nursing education including oriental nursing are critical.
Objective: This study is designed to investigate the effect of ankle joint position on hip extensor muscle activity when bridging exercise in sagittal plane. Design: Cross-sectional study Methods: The subjects were recruited from 20 healthy adult men. The subjects performed three types of bridging exercises (normal bridging, ankle dorsiflexion bridging, ankle plantar flexion bridging) three times for five seconds with a rest of 15 seconds between measurements and two minutes of rest between each motion. The target muscles were the gluteus maximus, biceps femoris, soleus, and tibialis anterior. A surface electromyography was used to measure the muscle activity of these muscles. Results: The results show there was no statistically significant difference between the three types of exercise in the gluteus maximus muscle activity. However, the biceps femoris showed a significant difference between the three types of exercises (p<0.05). Conclusions: In conclusion, when the three different bridging exercises were performed by adding ankle motion to normal bridging exercise, there was a significant difference in the muscle activity of the gluteus maximus relative to the biceps femoris muscle activity in the order of the ankle dorsiflexion bridging, normal bridging, and ankle plantar flexion bridging exercise. Therefore, this could be an effective option for a bridging exercise if applied to patients with a weak gluteal muscle and shortening of the hamstring muscle in further studies.
To investigate the radiation effect of P-32 on the soybean plants, the seeds treated with various levels of P-32 solution were sown and cultured in the pots. The growth of the plants and the contents of the macroelements were observed and the following results were obtained. 1) The linear growth of the plants at the early stage seemed to have been promoted by the low-level P-32 treatemnt. At the later growing stage, however, this difference among treatments were less conspicuous. 2) The plants of high level P-32 application showed some growth damaging symptom at the early growing stage. Later this damage was recorded as the time went on and these plants showed even better growth than the control. As a result at the late growing stage, they ensued highest growth. 3) The plants showed in general more growth at the low activity level than at the high-level at the early growing stage. At the late stage, however, the high-level activity promoted more growth than the low-level. 4) At the early growing stage P-32 treatment produced in general significantly more lower than control. At the later stage, however, this difference was not clearly seen. 5) The P-32 treatment seemed to have stimulated earlier florescence and this tendency was more clearly observable eapecially at the high activity level. 6) The weight of the air-dried seeds tended to be increased through P-32 treatment by 10-45%. This tendency was clearly observed especially at the low-level activity. 7) As for the contents of the various macroelements in the leaves, the nitrogen showed significantly larger contents at the middle level(S1) P-32 treatments. The phosphorous contents showed also highest at the middle levels activity and lower both at the high and low-activity levels. The potassium contents was proved, on the contrary, higher at the low-level activity and lower at the high-level. 8) The nitrogen contents in the stems was found significantly higher than control, except at the low-activity level. The phosphorous showed higher contents at the low-activity level and no significant difference at the high-activity level. As for the contents of potassium, calcium and magnesium, three seemed no significant difference among treatments. However, the magnesium showed somewhat higher content at the low-activity level, whereas the calcium was proved high than control. 9) The inorganic contents in the root showed that N and P in the P-32 treated plant were significantly higher than the control and the K-contents was, on the contrary, significantly higher at the control than the rest of the treatments. As for the calcium and magnesium there showed no difference among all treatments.
The purpose of this study was to analyze the kinematic variables of ankle joints and EMG signal of the lower limbs muscle activity for the different walking speed. The subjects were 6 males of twenties. It was classified into three different walking speed-0.75m/s, 1.25m/s, 1.75m/s. The walking performances were filmed by high speed video camera and EMG signal was gained by ME3000P8 Measurement Unit. Tibialis anterior(TA), Gastrocnemius medial head(GM), Gastrocnemius lateral head(GL), Ssoleus(SO) were selected for the dorsiflexion and plantarflexion of the ankle joint. The result of this study were as follows: 1. In the gait cycle, The time parameters for the phases were showed significant difference without the terminal stance phase and terminal swing phase for the different walking speed. 2. The angle of ankle joint was no significant difference for each time point and MDF, MPF but increasing walking speed the angle had the increasing pattern slightly. 3. The angular velocity of ankle joint was showed the significant difference for LHC, RTO, RKC, LHU, MPF and MDF point along the walking speed. 4. TA was showed about 2-3 times muscle activity at the 1.75m/s than 1.25m/s in some phases. And it was showed the similar muscle activity between the 0.75m/s and 1.25m/s but, showed a little much muscle activity in the 0.75m/s. GM was showed about 2-3 times muscle activity in the 1.75m/s than 1.25m/s, and even much muscle activity at the 0.75m/s than 1.25m/s in some phases. GL was showed increasing pattern of muscle activity specially in the initial swing phase as the walking speed increased. SO was showed about 3 times muscle activity in the 1.75m/s than 1.25m/s during the plantarflexion of ankle joint. It was showed the similar muscle activity between the 0.75m/s and 1.25m/s but, showed a little much muscle activity in the 1.25m/s.
This study deals with the following problems about leisure activity of young people and leisure guidance of mothers, (1) Leisure activity of children by the independent variables, (2) Leisure guidance of mothers by the independent variables. (3) The relation between leisure guidance of mothers and leisure activity of young people. This research used the questionaire survey. The subjects were 830 couples of mother and pupil (pupils of 4, 5 and t grades in six primary school in Kwang-Ju city). The statistics used for data analysis were percentage, t, F-test, X2. The results of this study are summarized as follows; (1) Boys and girls average leisure hours: week days…2 hour, saturday…3 hours, Sunday and holiday…4.5 hours, the school vacation…6.2 hours. And leisure activity showed the significant difference in sex, age, educational level, family form (p 0.001, p 0.05, p 0.010). Generally, they had social & amusing leisure activity. And a hindrance cause of leisure activ ty is due to hard working in learning practice. (2) The necessity of leisure activity showed higher in the aged mother and high educated mother, lower in the poor family. And guidance content showed the significant difference in sex of children(p 0.001), educational level of parents(p 0.05). Actually mothers wanted intellectual leisure activity. (3) The relation between the leisure activity pattern desired by leisure activity of mothers and children pattern showed that mothers demanded the various patterns, but children wanted social & amusing leisure activities mainly. Only children's patterns agreed with mothers in the artistic, intellectual, activities on Saturday and during the vacation. And the relation between mothers satisfaction degree in the leisure activity of children and children's satisfaction degree showed the significant difference (p 0.05). Children's satisfaction degree is high, irrespective of mothers satisfaction degree.
The purpose of the study was to examine the effect of ingestion of water or glycerol on renin activity, rectum temperature, blood electrolytes concentration in exercise. The present study took as its subjects five male students who major in physical education. The two different conditions were based on ingestion of water, ingestion of glycerol and a series of four blood gatherings were carried out at rest, at post-exercise 20 min, at post-exercise 40 min, at recovery. The findings of this study was as follows; On renin activity change, in the comparison within at rest ingestion of glycerol, ingestion of water were significant difference at post-exercise 20, 40 min (p<0.01). 2. On osmolality change, in the comparison within at rest, ingestion of glycerol was significant difference at post-exercise 40 min (p<0.05). ingestion of water was not. On Na and K concentration change, in the comparison within at rest, ingestion of glycerol was significant difference at post-exercise 40 min (p<0.05), ingestion of water was not. On Ca and Mg change, in the comparison within at rest, ingestion of glycerol, ingestion of water were no significant difference at all period.
Objective: Core training is a key exercise for conditioning and fitness programs, injury prevention, and more. This study aimed to find out the effect of adding dynamic core training, which is frequently prescribed in clinical practice, on dynamic balance and muscle activity compared to conventional static core training. Design: An experimental study Methods: This study is an experimental pilot study of prospective parallel design. Six healthy young adults were allocated to static core training group (SCG; crunch and plank) and blended group (BG; crunch, plank, and dead bug exercise) for two weeks to perform core training. Dynamic balance and muscle activity (erector spinae, rectus abdominis) were measured for all participants before and after core training. Results: All six healthy young adults enrolled completed the study. No significant difference was found before and after 6 sessions of core training in each group (P>0.05). Likewise, no significant difference was found in the results of the difference comparison between groups (P>0.05). Conclusions: In conclusion, in this experimental study, no difference was found when dynamic core training was added. Although the results before and after core training did not show improvement in dynamic balance and muscle activity, a randomized controlled trial is needed considering the results of previous studies and the limitations of this experimental study.
Purpose: This study was conducted in order to examine premenstrual symptoms (PMS) according to physical activity of high school girls. Method: Data were collected from 323 high school girls using structured questionnaires, Menstrual Distress Questionnaire (MDQ) and International Physical Activity Questionnaire (IPAQ). The data were analyzed using descriptive statistics, t-test, and AVOVA. Results: The mean score of PMS was low (2.200.81). Among the subcategories, negative feeling (2.491.26) was the highest. Physical activity levels were coded as inactive, minimal activity and health enhancing physical activity, among which minimal activity (53.0%) was the highest. Significant differences in PMS were observed according to subjective health condition (F=10.83, p<.001), alcohol intake (t=-1.99, p=.048), caffeine intake (F=3.04, p=.029), dietary habit (F=4.78, p=.009), amount of menstruation (F=4.57, p=.011), discomfort in daily life (F=28.94, p<.001), degree of menstrual pain (F=41.23, p<.001), method of menstrual pain relief (F=4.29, p=.015), and family history (F=11.45, p<.001). Significant difference in PMS was observed according to the physical activity level (F=3.12, p=.046), and health enhancing physical activity (2.540.87) was the highest. Conclusion: These findings suggest that PMS intervention programs would be considered factors related to PMS. Conduct of further studies is recommended for evaluation of the relationship between physical activity and PMS.
