Purpose: The purpose of this study was to evaluate the effect of web-based diabetic education on glycosylated hemoglobin(HbAlc) and self-care in people with type 2 diabetes. Method: Twenty-five patients were requested to input the blood glucose level weekly at http://www.biodang.com by cellular phone or wired Internet for one year. The researcher sent optimal recommendations weekly to each patient using the short message service for cellular phones and wired Internet. Results: Patients had a significant mean decrease in HbAlc, from 8.0% at pre-test to 6.9%, after three months and rested at 6.8% until 12 months. Patients had a significant mean increase in physical exercise adherence, from 3.3 days at pre-test to 4.1 days per week, after three months. Patients had a significant mean increase in foot care adherence, from 4.8 days at pre-test to 6.9 days per week, after one year. Conclusion: These findings indicate that Internet education could be used to improve HbAlc, physical exercise, and foot care adherence in type 2 diabetic patients.

The purpose of the study was to analyze kinetic factors required to the three-point jump shot of the basketball games through 3-D analysis and ground reaction force(GRF) analysis. Six university male players participated in this study. The results of the study were showed that (1) resultant velocity in the center of mass(COM) was $0.84{\pm}0.27\;m/s$ since a player didn't shot a ball in the highest peak and shot ball at the moment of going up forward and vertical movement. Therefore, it is necessary to find a proper timing to shot a ball; (2) the angular velocity was largely increased in upper arm and fore arm out of the upper-limb segments and the hands had the largest angular velocity since the body is in a fixed situation and angular speed is rapidly increased by the wrist' snap with the rapid movement of upper arm and forearm at the time of release a ball; (3) it is judged that a player can shot a ball at the accurate and high release point when the player collects power vertically to the maximum by keeping GRF to the right and the rear in a proper way and by keeping the body's balance so that a large power may not be dispersed.

The dissolution characteristics of DDB were markedly enhanced by preparing solid dispersions of drug with polyethylene glycol 6000. Solid dispersions of various weight fraction were formed by a melting method. And various tablets$(A{\sim}E)$ were prepared from these solid dispersions with excipients (lactose, com starch, Avicel and PVP) by wet granulation method. There were no significant differences in dissolution rates between physical mixture and DDB alone. But dissolution rates of solid dispersions were $1.4{\sim}2.0$ times greater than that of DDB alone and $1.2{\sim}1.8$ times greater than those of a commercial tablet.

The purpose of this study was to determine the effect of muscle contraction torque and muscle fatigue by low-frequency PC. In this article, We would like to experiment on electrical stimulation, determine optimal forms of stimulation setting. We used normal fourteen subjects(seven women, seven men) without neuromuscular disease and all subjects participated in the 3 session. Torque was measured using a computerized Kin-Com dynamometer for MVIC, MIC, Fatigue tests. The following results were obtained; 1. Torque of man were significantly higher than women in the MIC test(p<.05). 2. Torque of women, man were significantly decreased in the Fatigue test(p<.001). Between woman and man groups were significant difference(p<.05). These results lead us to the conclusion that muscle fatigue was influenced by PC, fatigue of women was higher than man. Therefore, A further studies concerning the electrical stimulation should consider differences between sexes in response to treatment and could enhance the development of the most effective treatment regimens.

Vehicular Ad-hoc Networks (VANETs) are comprised of wireless mobile nodes characterized by a randomly changing topology, high mobility, availability of geographic position, and fewer power constraints. Orthogonal Frequency Division Multiplexing (OFDM) is a promising candidate for the physical layer of VANET because of the inherent characteristics of the spectral efficiency and robustness to channel impairments. The susceptibility of OFDM to Inter-Carrier Interference (ICI) is a challenging issue. The high mobility of nodes in VANET causes higher Doppler shifts, which results in ICI in the OFDM system. In this paper, a frequency domain com-btype channel estimation was used to cancel out ICI. The channel frequency response at the pilot tones was estimated using a Least Square (LS) estimator. An efficient interpolation technique is required to estimate the channel at the data tones with low interpolation error. This paper proposes a robust interpolation technique to estimate the channel frequency response at the data subcarriers. The channel induced noise tended to degrade the Bit Error Rate (BER) performance of the system. Parallel concatenated Convolutional codes were used for error correction. At the decoding end, different decoding algorithms were considered for the component decoders of the iterative Turbo decoder. A performance and complexity comparison among the various decoding algorithms was also carried out.

This study was undertaken to determine the subjective symptoms of fatigue among the house-wives groups. Inquiries into subjective symptoms of fatigue were made by the form designied by the Industrial Fatigue Research Committee of the Japan Society of Industrial Health (1961), Comprising 30 items. These items are classified into 3 groups of 10 items, namely, A) Physical Symptoms, B) Mental Symptoms, C) Neuro-Sensory Symptoms (Figure 1 ). The results of the investigation can be summerized as follows: 1. Within the total items (T), the physical symptoms (A) were the strongest in the effect on the feelings of fatigue, and were followed by (B), and (C). 2. There was a significant difference shown in the distribution of responses by height (X$^2$=236.29, d.f. = 145, p < 0.00001). In the mental category (F = 2.22, d.f. = 4, p = 0.05) and neuro-sensory category (F = 2.64, d.f. = 4, p < 0.001), there was a difference in the responses’com-plaints by weight. 3. As for the ages, housewives at the age of 50 presented a higher rate than those 30 or 20. 4. Regarding the number of children, respondents have more children showed higher frequency rate of complaints. 5. In the investigation sample, complaints were related to education level (f = 18.34, d.f. = 3, p<0.0001) pentruation (t = 2.31, p< 0.022), and sleeping hours (F = 6.04, d.f. = 6, p< 0.0001).

The purpose of this study was to standardize the various methods and recipes of Hwajeun (glutinous rice pancake with flower) that appeare in the literature. For this purpose, the effects on sensory and physical characteristics of Hwajeun in various kinds of dipping syrups (S1 : honey, S2 : rice syrup, S3 : com syrup, S4 : sugar syrup and S5 : sugar) during storage for 24hrs were investigated. This experiment consisted of the measurement of water content, color difference meter, texture analyser and sensory evaluation for acceptance (color, flavor, moistness, softness, chewiness, adhesiveness, sweetness and overall acceptability). The moisture contents decreased with increasing storage time, indicating that S1 had a significantly (p<0.01) high value until 12hrs. The colorimetric values of lightness (L), redness (a) and yellowness (b) decreased and the total color difference values ($\Delta$E) increased with increasing storage time. In the two bite compression test, the hardness of S1 and S3 showed significantly (p<0.0001) lower values than other samples. As a result of the sensory evaluation for Hwajeun prepared with various kinds of dipping syrup, S1 and S3 were most preferred in color, flavor, moistness, chewiness, adhesiveness, sweetness and overall acceptability of sensory evaluation.

Bast fibers were applied for various usages from fabrics to household care products long time ago. In this study, we investigated the physical characteristrus of water retted & chemically rotted fibers of Yucca, New Zealand hemp, Corn, Kuzu vine, Indian mallow, and Mulberry paper that have been harvested by domestic cultivation. Water retting is more effective than chemical rotting for six kinds of plant fibers. When all fibers were rotted chemically with 1% sodium hydroxide, only Kuzu vine and Indian mallow were retted. Indian mallow, Yucca, New Zealand hemp, and Com fibers have higher tensile strength than any other fibers. The crystallinity of Kuzu vine, Indian mallow, Yucca, New Zealand hemp, and Corn was as low as 60% but Yucca, New Zealand hemp were flexible. Yucca had fewer lumina whereas New Zealand hemp more lumina in cross sectional shape. Especially com fibers have a structure like sponge, and Indian mallow had a net shape. The longitudinal section of New Zealand hemp showed smooth and long shape. Mulberry paper was proved to be short and thin, which is quite appropriate for making paper. In this study, we found that plant fibers for living material could be used for cloth materials.
