  • This study investigated the recruitment patterns of ten trunk muscles in isometric exertion tasks, focused on the functional roles (agonist or antagonist). Twelve male students performed maximum voluntary isometric exertion tasks towards six directions: flexion/extension, left/right lateral bending, and clockwise/counter-clockwise twisting. EMG signals from ten trunk muscles and exertion forces were collected. Normalized EMG (NEMG) values were calculated at 10, 20, 30, 40, 50, 60, 70, 80, and 90 %MVC. The subjects showed a limited capacity in producing twisting moments, approximately 50% of the extension moment, and 70% of lateral bending moments. EMG activity was dependent on the direction and magnitude of the exertion, and also on the functional role. The mean NEMG of agonist was 0.260 and 0.067 for antagonist. Agonists showed the highest mean NEMG in flexion (0.367), while antagonists showed the highest mean NEMG in twisting clockwise/counter-clockwise (0.090/0.106).

  • Osteoarthritis(OA) is a widespread, slowly developing disease with a high prevalence rate increasing with age. The most common big joints involved in OA is the knee, where the disease particulary strikes, causing difficulties in rising from a chair. climbing stairs, kneeling. standing, and walking. The primary complaints of these patients include pain, stiffness. instability, and loss of function. The purpose of this study was to assess the impact of self-reported symptoms and limited flexion, and limited extension on functional impairment in patients with knee osteoarthritis. In the data collection, a total of 206 who had visited the physiotherapy unit at six different departments of orthopedics were interviewed in K City from June to September, 2000. The results of the study summarized are as fellows: 1. There was a significant difference among different degree group of limited flexion(p<0.05). A group difference was demonstrated between <5 ${\sim}$ 15 and 16 > (F=16.21, p<0.05). In the relationship between the degree of limited flexion and the level of functional impairment, the h igher the range of limited flexion, the lower the level of functional impairment. 2. In the relationship between the degree of limited extension and the level of functional impairment, a group difference was revealed between the non-limitation group and the <10 and 11 < However, no significant difference was noted between 11 ${\sim}$ 20 and 21 >(F= 13.37, p<0.05). In conclusion, finding above suggest that functional impairment is closely correlated with limited tlexion and extenion

  • Objective: Bilateral movement training is an effective method for upper extremity rehabilitation of stroke. An approach to induce bilateral movement through functional electrical stimulation is attempted. The purpose of this study is to develop an EMG-triggered functional electrical stimulation device for upper extremity bilateral movement training in stroke patients and test its feasibility. Design: Feasibility and Pilot study design. Methods: We assessed muscle activation and kinematic data of the affected and unaffected upper extremities of a stroke patient during wrist flexion and extension with and without the device. Wireless EMG was used to evaluate muscle activity, and 12 3D infrared cameras were used to evaluate kinematic data. Results: We developed an EMG-triggered functional electrical stimulation device to enable bilateral arm training in stroke patients. A system for controlling functional electrical stimulation with signals received through a 2-channel EMG sensor was developed. The device consists of an EMG sensing unit, a functional electrical stimulation unit, and a control unit. There was asymmetry of movement between the two sides during wrist flexion and extension. With the device, the asymmetry was lowest at 60% of the threshold of the unaffected side. Conclusions: In this study, we developed an EMG-triggered FES device, and the pilot study result showed that the device reduces asymmetry.

  • The concept of an extension α-F-contraction and it's modified counterpart represents an advancement in the theory of metric space contractions. Through our study of the contraction principles and it's relationship to extension and modified extension, we found different conditions somewhat lengthy. In our paper, we create a development of the conditions for the extension of α-F-contraction and a modified α-F-contraction by reducing the conditions and make them easier. Our propose conditions are notably simple and effective. They serve as the foundation for proving theorems and solving examples that belong to our study. Moreover, they have remarkable significance in the condition of mathematical analysis and problem-solving. Thus, we find that these new conditions that we mention in the definitions achieve what is require and through them, we choose λ = 1 and we choose λ ∈ (0, 1) to clarify our ideas.

  • The purpose of this study is to explains consumers' medical discourse embedded in the consumption of oriental medicine and health functional foods. Despite the fact that both of oriental medicine and western medicine is legally accepted, people tend to recognize that accurate diagnosis is possible only in the latter. As the discourse that oriental medicine, compared with western medicine, has an auxiliary position is widely spreaded, the rivalry between herbal medicine and health functional foods come to be formed. And it led to a close correlation between the decrease of herbal medicine consumption and the growth of health supplement market. Herbal medicine is compared to red ginseng, one of the representative health supplement. Negative notion such as using an Asian herb from China and side effect of hepatotoxicity influences herbal medicine consumption. This study argues two conclusion. First, the correlation between the consumption of herbal medicine and that of health functional foods results from the discourse of scientific reconstruction, standardization, and commercialization all of which come from globalization discourse. Second, medical discourse embedded in these commodity, in the end, has impact on agricultural production.

  • Mulberry (oddi) is one of the most popular functional foods with many physiological components. This study investigated and compared the nutritional compositions and physiological activities of four mulberry fruits from Morus albo L. including Cheongilppong, Iksuppong, Suwonppong and Cheongsuppong (a new cultivar from Chungcheongbuk-do). To analyze the nutrient contents, mulberry fruits were freeze-dried. The results showed that the proximate compositions of the four mulberry cultivars ranged from 9.61~14.11% for moisture, 8.28~11.90% for crude protein, 3.70~4.86% for crude ash, 4.28~5.54% for crude lipid and 7.46~10.78% for crude fiber. The above proximate contents of mulberry cultivars were not significantly different. However, Cheongsuppong had the highest content of reducing sugar, 74.7%. Chungsuppong and Iksuppong showed higher contents of total polyphenol and anthocyanin than other mulberry cultivars, while all mulberry cultivars showed high antioxidant activities. Hypoglycemic effect had a slightly higher level in Suwonppong and Cheongsuppong than in the other samples. Taken together, the new cultivar "Cheongsu" oddi can be suggested as a potential source of functional food.

  • In this note, we extend the concepts of linearly positive quadrant dependence to the random vectors and prove a functional central limit theorem for positively quadrant dependent sequence of $R^d$-valued or separable Hilbert space valued random elements which satisfy a covariance summability condition. This result is an extension of a functional central limit theorem for weakly associated random vectors of Burton et al. to positive quadrant dependence case.
