Purpose : The purpose of study was to determine effects of Proprioceptive Neuromuscular Facilitation pattern exercise with Swiss ball exercise and Swiss ball exercise on balance in the 40 students from H university. Method : There were two experimental conditions. There were two difference groups in the experimental conditions, which had to perform different exercise tasks: Swiss ball exercise group (n=20) and Proprioceptive Neuromuscular Facilitation exercise with Swiss ball exercise group(n=20). The experimental group received Proprioceptive Neuromuscular Facilitation exercise for 20minutes and Swiss Ball exercise for 40minutes, 3 times a week for 4weeks. While another experimental group received Swiss Ball exercise for 40minutes, 3 times a week for 4weeks. In order to evaluation effects of the Proprioceptive Neuromuscular Facilitation pattern exercise with Swiss Ball exercise and Swiss Ball exercise in the two different experimental group, subjects was measured by static balance. Statistical analysis was the paired t-test to compare the differences within groups and the SPSS to analyze the differences between groups. Results : The result of this study were as follows: The static balance was higher for the two different experimental group in post-exercise than in pre-exercise(P<0.5). Proprioceptive Neuromuscular Facilitation pattern exercise with Swiss Ball exercise experimental group was significant difference better then another experimental group(P<0.5). Conclusion : The Proprioceptive Neuromuscular Facilitation pattern exercise with Swiss Ball exercise can result in improved static balance better then Swiss Ball exercise.

In rocky intertidal habitats, abiotic stress due to desiccation and thermal extremes increases with elevation because of tides. A study in Atlantic Canada showed that, at low elevations where conditions are benign due to the brief low tides, fucoid algal canopies (Ascophyllum nodosum and Fucus spp.) do not affect the structure of benthic communities. However, at middle and high elevations, where low tides last longer, fucoid canopies limit abiotic extremes and increase the richness (number of invertebrate and algal species, except fucoids) of benthic communities. Using the data from that study, this paper compares the intensity of facilitation and its importance (relative to all other sources of variation in richness) between middle and high elevations, which represent intermediate and high stress, respectively. Facilitation intensity was calculated as the percent increase in benthic richness between quadrats with low and high canopy cover, while the importance of facilitation was calculated as the percentage of variation in richness explained by canopy cover. Data for 689 quadrats spanning 350 km of coastline were used. Both the intensity and importance of facilitation were greater at middle elevations than at high elevations. As canopies do not affect benthic communities at low elevations, this study suggests that the facilitation-stress relationship at the community level is unimodal for this marine system. Such a pattern was found for some terrestrial systems dominated by canopy-forming plants. Thus, it might be ubiquitous in nature and, as further studies refine it, it might help to predict community-level facilitation depending on environmental stress.

The aim of this study was to determine the effect of action observational physical training (AOPT) on manual dexterity and corticomotor facilitation in stroke patients. Ten hemiparetic patients participated in this study. Each subject was asked to participate the three conditions; base condition (Base), physical training (PT), AOPT. Participants were asked to observe the action in the video that a therapist moved the blocks during the AOPT conditions. Corticomotor facilitation was determined in three conditions by monitoring changes in the amplitude of motor-evoked potentials (MEPs) elicited in hand muscles by transcranial magnetic stimulation. MEP responses were measured from the first dorsal interosseous after participants attended to three conditions. For the manual dexterity, Box and Block test (BBT) was used. The results of present study were summarized as follows: MEPs amplitude significantly tended to be larger than PT and Base condition. The scores of BBT in the AOPT condition were also significantly larger than other conditions. In conclusion, this finding of present study indicates that physical training for observation of an action is beneficial for enhancing a dexterity of paretic arm in stroke patients.

Purpose: This study assessed the current working conditions and job satisfaction on aquatic therapy performed by physical therapists in South Korea. Methods: A total of 139 (managers: 53, staff: 86) physical therapists participated in this survey (90 questionnaires) and the data were analyzed using the SPSS 21.0 Windows. Results: The retention conditions of aquatic therapy facilitation was high in the rehabilitation centers (or disabled living facilities) and rehabilitation hospitals. On the other hand, there were regional variations. The physical therapists in this field were likely to have limitations or restrictions of professional aquatic therapy education. The subjects showed a tendency for a career interruption during their fifth working year. The overall job satisfaction on aquatic therapy of physical therapists was high (managers: 94.3%, staff: 95.3%, p=0.276), but the work intensity was higher than the other parts of physical therapy and the relative reward was comparatively low (managers: 60.3%, staff: 66.3%, p=0.865). Conclusion: Based on this study, the current working conditions regarding aquatic therapy by physical therapists were assessed. These results will help enhance aquatic therapy and/or in aquatic therapy facilitation.

Purpose: This study sought to compare the muscle activity of the deltoid muscle according to the range of motion during the proprioceptive neuromuscular facilitation (PNF) upper extremity D2 pattern exercise performed with an isokinetic exercise device. The aim was to provide basic data for selecting an exercise for the relevant segment of the range of motion to enhance function in clinical practice. Methods: In this study, the relevant measurements of the anterior and middle trapezius of 25 healthy adults were taken using a surface electromyography system. The upper extremity pattern exercise was performed in three ranges (0% to 50%, 50% to 100%, and 25% to 75%) using the upper extremity isokinetic device. Results: There was a statistically significant difference in the muscle activity ratios of the anterior and middle deltoid muscles according to the measurement conditions (p<0.05). There was a statistically significant difference in the activity ratio of the middle deltoid muscle according to the measurement conditions in the ratio from the start range to the end range (p<0.05). There was no significant difference in the muscle onset time difference according to the measurement conditions (p>0.05). Conclusion: The muscle activity of the anterior and middle deltoid muscles was analyzed according to the range of motion during the PNF upper extremity pattern exercise performed with an isokinetic device. The results could be used as a basis for selecting exercises for the relevant segment of the range of motion according to the function to be emphasized.

This paper evaluates whether the proposed FTAAP is a desirable policy option for APEC member economies and the world economy. More specifically, this paper qualitatively investigates whether the FTAAP satisfies conditions for a trade bloc to generate positive and sufficient net trade creation effect. In addition, this paper estimates the likely impact of the FTAAP by using a CGE model analysis. From the qualitative analysis based on statistical data, this paper strongly argues that the FTAAP can be a desirable regional trade bloc able to generate positive gains from freer trade. From the ex-ante scenario analysis using both static and capital accumulation CGE Models, this paper concludes that the FTAAP has great potential for improving welfare of participating APEC economies and will boost economic growth in the region. In particular, the FTAAP would be even better if it can be linked with liberalization of trade in services and enhanced trade facilitation.

The purpose of this study was to see whether Korean-English bilinguals' semantic systems of Korean and English are shared or separated between the two languages. In a series of picture-word interference tasks, participants were required to name the pictures in Korean or in English with distractor words printed either in Korean or English. The distractor words were any of identical, semantically related, or neutral to the picture. The response time of naming was facilitated when distractor words were semantically identical for both same- and different-language pairs. But this facilitation effect was stronger when naming was produced in their native language, which in this case was Korean. Also, inhibitory effect was found when the picture and its distractor word were semantically related in both same- and different-language paired conditions. From these results it can be concluded that semantic representations of Korean and English may not be entirely but partly overlapping in bilinguals.
