본 연구는 녹비작물-벼 재배 작부체계에서 볏짚과 녹비작물을 전량 회수하여 사료작물로 활용시 농경지 비옥도 관리를 위한 양분수지를 평가하였다. 녹비보리와 헤어리베치 혼파비율에 따른 녹비작물 생산량은 B75H25에서 가장 높게 나타났다. B75H25 처리구의 벼 수량은 NPK 처리구 대비 90%를 보였다. 녹비작물과 볏짚을 전량 회수시 NPK, B100, B75H25, B50H50, B25H75, H100 처리구의 질소 수지는 각각 2.0, -80.8, -104.0, -93.5, -82.9, 76.2 kg N/ha 이었다. 그리고 질소 수지가 가장 낮은 B75H25 처리구의 인산수지는 -50.3 kg P/ha로 가장 낮았다. 따라서 녹비작물-벼 재배 작부체계에서 녹비작물과 볏짚을 전량 사료로 활용시 농경지 비옥도 유지를 위해서 각각 약 90 kg N /ha, 50 kg P/ha의 질소와 인산 시비가 필요한 것으로 나타났다. 그리고 금후 녹비작물을 사료로 활용하고자 할 경우 화학비료 시용량과 적정 녹비작물의 회수량에 관한 연구가 필요한 것으로 판단된다.

The purpose of this study was to analyze and compare the effect of resistance exercise and balance exercise on proprioception and WOMAC index of patients with degenerative knee osteoarthritis. A total of 40 subjects participated in this study. The subjects were diagnosed with degenerative knee osteoarthritis and all were more than 60 years old. They were divided into three groups. Group I(n=8) was trained with resistance exercise, Group II(n=6) was trained with balance exercise and Group III(n=6) was trained with range of motion as a control. The results of this study were as follows. It was significantly indicated that the resistance exercise group and balance exercise group elicited error-reduction on proprioception goal-angle (p<.05). There was a statistically significant difference on proprioception between resistance exercise group and control(range of motion) group. There was a statistically significant reduction on WOMAC index between resistance exercise group and balance exercise group (p<.05) and on the WOMAC index between resistance exercise group and range of motion group(p<.05). In conclusion, resistance exercise and balance exercise are effective on degenerative knee osteoarthritis and resistance exercise is the most effective for improving proprioception and WOMAC index. More research on the intervention according to the degree of degenerative knee osteoarthritis is needed.

Purpose: The aims of this study were to determine if game-based training with constraint-induced movement therapy (CIMT) is effective in improving the balance ability in female patients with a total knee replacement, and to provide clinical knowledge of CIMT game-based training that allows the application of total knee replacement. Methods: Thirty-six patients who had undergone a total knee replacement were assigned randomly to CIMT game training (n=12), general game training (n=12), and self-exercise (n=12) groups. All interventions were conducted 3 times a week for 4 weeks. All patients used a continuous passive motion machine 5 times a week and 2 times a day for 4 weeks. The visual analog scale (VAS), muscle strength of knee flexion and extension, and range of motion (ROM) of knee flexion and extension were assessed, and the functional reach test (FRT), and timed up and go (TUG) test were performed to evaluate the balance ability. Results: All 3 groups showed significant improvement in the VAS, knee flexion and extension muscle strength, FRT, and TUG test after the intervention (p<0.05). Post hoc analysis revealed significant differences in FRT, and TUG of the CIMT game training group compared to the other group (p<0.05). Conclusion: Although the general game training and CIMT game training improved both the knee extension muscle strength and dynamic balance ability, CIMT game training had a larger effect on dynamic balance control.

The purpose of this study is to examine the influence of a horse riding simulator and galvanic vestibular stimulation on improving the ability to balance posture and proprioception. Thirty healthy adults participated and were randomly assigned to a horse riding simulator group ($n_1$=10), galvanic vestibular stimulation (GVS) group ($n_2$=10), control group ($n_3$=10). Experiment groups were trained 3 times per week over 6 weeks. The ability to balance posture was measured by force plate and proprioception was measured by Joint position sense. The following results were obtained. the changes of balance index were significant interaction in each group in accordance with the experiment time in 0, 3 and 6 weeks (p<.05). All groups showed the most decreasing pattern compared with the control group. But was not statistically significant. Proprioception was significant interaction in each group in accordance with the experiment time (p<.05). All groups showed the most decreasing pattern compared with the control group. The above results indicated that the 6 weeks horse riding simulator and galvanic vestibular stimulation training demonstrated positive effects in the ability to balance posture and proprioception. These results suggest that the horse riding simulator and galvanic vestibular stimulation training could be therapeutic intervention that can improve balance and postural control.

Purpose: Menstruation is associated with menstrual symptoms like pain and balance problems which have an impact on the quality of life. Pilates increases pelvic stability and reduces menstrual pain by inducing abdominal muscle contraction. This study was done to evaluate the effects of Pilates on menstrual pain, symptoms, balance, and quality of life when compared to aerobic exercise. Methods: Thirty-nine women with menstrual pain were randomly divided into the Pilates group (n=13), aerobics group (n=13), and control group (n=13). The Pilates group performed lumbar-pelvic stabilization exercises, while the aerobic group ran on a treadmill. The control group did not undergo any intervention. The experimental groups exercised for four weeks (12 sessions) and did not exercise during menstruation. The Y-balance test was performed on the second day of menstruation to evaluate dynamic balance. The questionnaires administered immediately after menstruation were the visual analog scale (VAS), Korea Oswestry Disability Index (ODI), and the modified Menstrual Distress Questionnaire (MDQ). The paired t-test was used to compare the effect of exercise within the three groups and a oneway analysis of variance was used to compare between groups. Results: VAS and MEDI-Q scores significantly decreased in the Pilates group after 4 weeks compared with those in the aerobic and control groups. Moreover, ODI and Y-balance scores increased in the Pilates group compared with those in the aerobic and control groups (p<0.05). Conclusion: The Pilates stabilization exercises are effective and help in improving menstrual pain, balance and other menstrual symptoms assessed through ODI, and MEDI-Q, compared to aerobic exercises.

PURPOSE: This study was conducted to determine the effects of treadmill gait training with obstacle-crossing on the static and dynamic balance ability of patients with post stroke hemiplegia. METHODS: Twenty-one patients with post stroke hemiplegia were divided into three groups as: treadmill gait training with obstacle-crossing (TOG, n=7), treadmill gait training without obstacle-crossing (TGG, n=7) and a control (CON, n=7). TOG and TGG performed exercise for 20 minutes, three times a week for 8 weeks. Static balance ability (stability typical, ST; weight distribution index, WDI; fourier harmony index, FHI; and fall index, FI) and dynamic balance ability (berg balance scale, BBS and timed up and go test, TUG) were measured before and after 8 -weeks in each exercise group. Statistical analyses were conducted using two-way ANOVA with repeated measures, a paired t-test, and multiple comparisons according to Tukey's HSD. RESULTS: FHI and BBS were significantly increased at TOG (p<.01) and TGG (p<.05) after 8-weeks compared to before treadmill gait training with obstacle-crossing. FHI and BBS were significantly increased at TOG compared with CON and TGG (p<.05). CONCLUSION: Treadmill gait training with obstacle-crossing was more effective than that without obstacle-crossing to improve posture control and independent daily life performance of hemiplegia patients.

Purpose: The purpose of this study was to investigate the effect of balance using ankle strategy during adjusted balance training and muscle training in normal young female adults. Methods: There were eighteen participants. All subjects were randomly assigned to three groups, the control group (n=6), the adjusted balance training group (n=6) and the muscle training group (n=6). Subjects were assessed for each subject by a pretest and a posttest at 1 week, 2 weeks, and 3 weeks, measuring the anterior-posterior limit of stability, trace length and EMG data for the tibialis anterior and lateral gastrocnemius. Results: The anterior-posterior limit of stability significantly increased in the training group (p<0.05). The trace length significantly decreased in the training group (p<0.05). The muscle activity of the tibialis anterior and lateral gastrocnemius also significantly decreased in the training group (p<0.05). Conclusion: We confirmed that both the balance training group and the muscle training group significantly increased the anterior-posterior limit of stability and decreased trace length and muscle activity. Further studies are needed to analyze the long-term effects on subjects resulting from these changes.

Purpose : The goal of this study was to identify the effects of treadmill walking training (TW) and ergometer bicycle training (EB) on gait and balance in stroke patients. Methods : The subjects consisted of 42 stroke patients. They were randomly divided to two groups: TW(n=20) and EB(n=22). Each group trained along with the conventional physical therapy, three times a week for six weeks. The ability of gait was assessed by the 10m walk test and Timed Up and Go test(TUG). The ability of balance was assessed by Berg Balance Scale(BBS) and Balance Performance Monitor(BPM). Results : There was no significant difference between the 10m walking test and TUG groups, but there was a statistical difference between before and after the training for all groups. The result of BBS that assessed balance showed a significant reduction between before and after the training for all groups, but there was no difference between the two groups. While the two groups showed no difference in the BPM assessment, only the EB showed a significant improvement of before and after the training in each group. Conclusion : The outcomes suggest that stroke patients can improve their gait and balance performance through the TW and EB trainings. Although dynamic mean balance showed significance from EB, no significant difference was found between two groups. Even though it cannot be determined through this study which training group is more effective among the above mentioned two, it could be suggested that each training is effective to gait ability and the ability of balance of stroke patients.
