Purpose: The purpose of this study was to investigate the impact of action observation training (AOT) on the balance and cognition of the elderly with dementia. Methods: Twenty-four participants were randomly assigned to experimental and control groups (12 participants each). The 5-week intervention involved 45 minutes sessions, three times a week. Both groups did 30 minutes of general physical exercises, followed by the experimental group watching a 5 minutes video featuring functional movements and imitating them for 10 minutes. The control group watched a scenic video and did functional training for 10 minutes, mimicking the experimental group. All participants were evaluated using the Timed Up and Go (TUG) test, Functional Reaching Test (FRT), Berg's Balance Scale (BBS), and Korean version of Mini-Mental State Examination (K-MMSE) before and after the intervention. A paired t-test was conducted to compare the within-group change before and after the intervention. Two-way repeated measures ANOVA was performed to compare the between-group difference. The statistical significance level was set to p=0.05 for all variables. Results: The experimental group showed significant within-group changes in the TUG test, FRT, BBS, and K-MMSE (p<0.05). The control group showed a significant change in FRT and K-MMSE (p<0.05). A significant difference was observed between the experimental group and the control group regarding the change in the TUG test, BBS, and K-MMSE after the interventions (p<0.05). Conclusion: The findings of this study suggest that the AOT and repetition of actual movements, led to more significant improvements in balance and cognitive abilities compared to the control group that observed scenic landscapes.

To determine the degree of variability among the host plant species in their abilities to become colonized by arbuscular mycorrhizal fungi (AMF), the inoculum for AMF was collected from the various sites in Korea and was inoculated to the three horticultural plants; Tagetes patula, Torenia fournieri, and Salvia splendens. After 4-month growth under greenhouse, mycorrhizal root colonization rates and spore density were measured. The roots of T. patula showed higher colonization rate than both plants of T. fournieri and Salvia splendens. The mycorrhizal root colonization was influenced by both of the AM fungal inoculum and the host species or their interactions. The combination of the host and fungal species was suggested to be important for the application of AMF to horticultural crops.

BACKGROUND The purpose of this study was to investigate disability of the patients after stroke, clinical applicability and usefulness of the FIM in evaluating the functional abilities and to assess the characteristics of the patients after stroke. And this study examined difference by predictive factors on the treatment outcome. METHOD The study was composed of 31 stroke patients who were within 1 week after stroke and had been treated in hospital more than 4 weeks. Improving rate was measured by using the Functional Independence Measure(FIM), and the correlation was analyzed between Motor FIM and Cognitive FIM. We analyzed significant meaning statistically in the mean value of FIM. RESULT 1. There was no significant meaning statistically in the mean value of FIM that was between both at admission and after 2 weeks. But there was proportional correlation between both at admission and after 4 weeks, and significant meaning statistically. 2. There was proportional correlation between both FIM and Motor FIM, and significant meaning statistically. But there was no significant meaning statistically between both FIM and Cognitive FIM. 3. There was no significant meaning statistically between both FIM and sex, age, side of weakness, stroke subtype, hypertension, hypercholesterolemia, diabetes mellitus, heart disease, starting point of rehabilitation therapy and past history of cerebral vascular accident. While dysarthria affected functional recovery in stroke patients, and significant meaning statistically. CONCLUSION 1. FIM appeared to be a valid and reliable method to measure the functional abilities of the patients after stroke. 2. Only one thing between Motor FIM and score didn't influence FIM score. 3. Dysarthria affected functional recovery in stroke patients, and it is the statistically significant factor.

The new course distances of a ship are one of the important factors of the safety handling as the indices to indicate directly her abilities of course alteration. Recently, International Maritime Organization (IMO) exhorts that all vessels should use maneuvering booklets in which are drawn the curves of new course distances obtained from the test of measuring them and noted other maneuvering performance standard in various navigation conditions. This paper describes the method to calculate many new course distances for many rudder angles by turning circle test without observation or using other calculating methods. The main results are as follows: 1) The mean difference of the distances between two new course distances by the turning circle test and heading test of the experimental ship was about 7.7% vaules of the ones by the heading test. when her altering angles were $48^{\circ}$, $63^{\circ}$and $70^{\circ}$, using the rudder angle of $35^{\circ}$ . These new course distances were therefore found to be small in difference of those. 2) The mean difference of the distance between two new course distances by the turning circle test and the maneuvering indices of the experimental ship was about 4.5% values of the ones by the maneuvering indices, when her altering angles were $48^{\circ}$, $63^{\circ}$and $70^{\circ}$, using the rudder angle of $35^{\circ}$, these new course distances were therefore found to be small in difference of those. 3) The mean difference of the distance between two new course distances by the turning circle test and the observation of the experimental ship was about 6.1% values of the ones by the observation, when her altering angles were $48^{\circ}$, $63^{\circ}$and $70^{\circ}$, using the rudder angle of $35^{\circ}$. These new course distances were therefore found to be small in difference of those. 4) It is confirmed that many new course distances for many angles can be calculated easily by using the method of ship's simple turning circle test, without observation or using the maneuvering indices and heading test method. 5) It is considered to be helpful for the safety of ship handling to draw curves of new course distances by turning circle test and $\phi_4$ - $\phi_2 by heading test, and utilize them at sea.
