Back extension exercises have been used for rehabilitation of the injured low back, prevention of injury, and fitness training programs. However, excessive loading on low back can exacerbate existing structural weakness. The purpose of this study was to compare muscle activity of low back muscles during back extension exercises. Twenty healthy male subjects were evaluated, Electromyographic (EMG) activities of low back muscles at L1 and L5 level were recorded during seven different back extension exercises and two reference tasks by surface EMG and saved for data analysis. Reference tasks of lifting 20% and 40% of their body weight were included for comparison. The result were as follows: 1) Single-arm extension and single-leg extension exercises on quadruped position appeared to constitute a low-risk exercise for initial extensor strengthening. 2) When arm extension was combined with contralateral leg extension on quadruped position, EMG activities of low back muscles were increased, 3) EMG activity of low back muscles was highest during the trunk extension exercises on prone position. 4) EMG activities of low back muscles during arm and leg extension exercises on quadruped position were less than those of reference task of lifting 40% of their body weight. These results have important implications for progressive back extensor muscle

Nano-sized silver catalysts have been prepared by alcohol and dioctyl esterof sodium sulphosuccinic acid, anionic surfactant, Aerosol OT(AOT). TOD/TPR andethylene oxide activity have been studied to investigate the characteristics of silvercatalysts. The sizes of Ag particles were estimated to be 10∼16 nm and the peak ofsilver oxide was not observed by XRD except for metallic silver. The desorptionpeak of molecular oxygen by TPD/TPR uniqely observed at about 400 ℃ in thecatalyst prepared by water-alcohol method. However, in the catalyst prepared bymicroemulsion method, the desorption peaks of molecular and atomic oxygens wereobserved at about 400 ℃ and 600 ℃, respectivly. The catalyst prepared by water-alcohol method showed higher activity ethylene oxide than the catalyst prepared by microemulsion method. It eems due to the larger silver particles and easier desorption of molecular oxygen from the catalyst prepared by water-alcohol method.

Statistical total information was suggested by modifying Gell-Mann's total information in the process of dividing by bit number of composing elements. Results of application satisfied set condition of information suggested by Gell-Mann, converged in the case that all elements are known, and expressed the differences with deterministic information. To find the relation with real value, total information gathered in Encyclopedia regressed with land value and showed significant relation. Further research on automatic gathering information in more stable IGUS like internet would benefit assessing ambiguous value like environment and human feeling.

Mobile nodes in ad hoc mobile networks typically communicate over wireless channels and are capable of movement. These are networks that support multihop communication and can be formed on a temporary basis. This paper proposes a solution that allows mobile nodes to access the wired Internet and to roam from base station to base station. And we also develop the efficient method that adapts in Global MANET which can be changed over time. It is observed that we can reduce not only error detection time but also network load, thus increasing the data reception rate in Global MANET Environment.

Objective: The Lispro insulin has faster onset of effects and shorter duration than the human regular insulin, an analog of human insulin. The differences in the pharmacodynamics between the two types of insulin in the continuous subcutaneous insulin infusion(CSII) with insulin pump for treating the Korean Type 2 DM patients were analyzed. The effects on the regulation of blood sugar, the amount of insulin injected, and the frequency of hypoglycemia were compared between the lispro insulin and the regular human insulin. Method and Material: One hundred and three Korean Type 2 DM patients were randomly divided into two groups, 49 Lispro insulin and 54 Regular insulin.(Table 1) Both groups were treated for 14 days. Also at a set time before meal, insulin was injected as bolus, using a portable insulin pump, in both groups, 15 minutes before for lispro insulin and 30 minutes before for human insulin The HbA1C, C-peptide, AC/PC, height and weight were measured for each patients at the time of admission. The peripheral blood sugar level and insulin injection profile were recorded 7 times per day for each patients. Results: After treating for 7 days and 14 days, the blood sugar level normalized in both groups. There weren't any significant differences in blood sugar levels in both groups at point of the study, and also there weren't any differences in the frequency of hypoglycemia. In order to maintain the normalized blood sugar level, the lispro insulin group had higher total daily insulin requirement than the regular insulin group after 14 days of treatment (0.90±0.35 vs 0.73±0.39u/kg/day, p<0.05) This difference is probably due to the difference in basement insulin requirements rather than prandial insulin requirements (0.32±0.1 vs 0.43± 0.09u/kg/day, p<0.001). Discussion: In the hospitalized Korean Type 2 DM patients with CSII treatment, continuous subcutaneous insulin infusion therapy using lispro insulin has convenience in usage compared to the regular insulin. However, there were not any differences in the blood sugar levels. Also lispro insulin requires more insulin in order to maintain normal blood sugar level, which is probably due to the increase in the basal requirement. Also there were not any difference in the frequency of hypoglycemia.

Renal cell carcinoma is the third most common neoplasia of the genitourinary tract. Its most common type, representing 60% of the cases, is the clear cell carcinoma, with an incidence peak between 50 and 70 years. Metastases are present at the time of diagnosis in approximately 30% of the patients, the major sites being lungs, bones, skin, liver, and brain. But distant metastasis of malignant neoplasm to the masseter muscle is extremely rare. We report a case of renal cell carcinoma (RCC) metastasizing to the masseter muscle.

We investigated the variation of PR signals for n-GaAs surface treated with Fe as annealing method. The samples were annealed by isochronal(200∼600 ℃, 10 min) and isothermal(300 ℃, 10 ∼60 min) method. In PR signals measured from isochronal annealed samples, the rate of intensity decreasing for n-GaAs was 49%, and that for n-GaAs surface treated with Fe was 66%. We assumed that the large amount of decreasing intensity for Fe contaminated sample caused by decreasing carrier density due to increasing of ?? neutral acceptor at higher annealing temperature. In PR signals measured from isothermal annealed samples, the signals for annealed n-GaAs decreased with increasing annealing time, and the signals for n-GaAs surface treated with Fe continuously increased with increasing annealing time. It can be assumed that the increasing of PR intensity for Fe contaminated samples as annealing time caused by the diffusion of Fe atoms from the surface.

연구목적 : 저자들은 알코올의 진정 작용과 수행 붕괴 효과에 대한 카페인의 영향을 확인하기 위해 이 연구를 시행하였다. 방 법 : 건강한 19세에서 25세 사이의 대학생 지원자 14명을 대상으로 Epsworth Slippiness Scale(ESS), Stand-ford Sleepiness Scale(SSS), Visual Analogue Sclae(VAS), Vienna test, Multiple Sleep Latency Test(MSLT) and Breath Ethanol Concentration(BrEC)을 측정하였다. 결 과 : 알코올(1.0g/㎏)은 투여 후 5시간까지 입면잠복기를 단축시키며, 카페인(300mg)은 이러한 단축을 현저히 개선시키는 반전 효과가 있었다. 알코올(1.0g/㎏)은 투여 후 3~5시간 동안 주간 졸음과 피로감을 유발하며, 카페인(150~300mg)은 졸음과 피로감을 개선시키는 효과가 있었다. 경계력은 알코올(0.5~1.0g/㎏) 투여 1시간 후 유의하게 저하되었고 카페인(150~300mg) 투여 3시간 후부터 개선되었으며, 집중력은 알코올(1.0g/㎏) 투여 후 변화가 없었으나 카페인 투여 3시간 후부터 유의하게 향상되었고, 단기 기억은 알코올과 카페인 투여에 유의한 변화가 나타나지 않았다. 기준일, 알코올 투여일, 알코올 및 카페인 투여일에서 각 변량(SSS, MSLT, 졸음, 피로감, 기분, 집중력, 경계력, 단기 기억력)간에는 일관성 있는 유의한 관계가 나타나지 않았다. 정상인에서 알코올은 입면잠복기를 단축시키고 주간 졸음과 피로감을 유발하며, 카페인은 알코올에 의해 유발된 입면잠복기의 단축을 연장시키고 주간 졸음과 피로감 및 경계력과 주의 집중력을 개선시키는 효과가 있었다. 결 론 : 카페인은 알코올의 진정 및 수행 붕괴 효과를 반전시키는 효과가 있음을 알 수 있었다. Objectives : The authors performed this study to identify the effects of caffeine on the alcohoi's sedative and performance disruptive effects. Methods : Epsworth Sleeppiness Scale(ESS), Stanford Sleepiness Scale(SSS), Visual Analogue Scale WAS), Vienna test, Multiple Sleep Latency Test(MSLT) and Breath Ethanol Concentration(BrEc) were checked for the 74 young and healthy college student volunteers aging from 19 to 25 years. Results : Alcohol(1.0g/kg) freduced sleep latency until 5 hours after administration and caffeine(300mg) reversed this effect significantly. Alcohol(1.0g/kg) induced daytime sieepiness and fatigue 3-5 hours after administration and caffeine(l50-300mg) improved sleepiness and fatigue. Vigilance was decreased significantly 1 hour after alcohol administration(0.5-1.0g/kg) and improved 3 hours after caffeine administration(l50-300mg) and attention was not changed after alcohol administration(1.0g/kg) but improved significantly 3 hours after caffeine administration and short-term memory was not changed significantly after alcohol and caffeine administration. On the baseline, the day of alcohol administration only, and alcohol and caffeine administration day, between each vanable(SSS, MSLT, sleepiness, fatigue, mood, vigilance. concentration, and short-term memory) did not show significant consistent correlation. Conclusion : Alcohol decreases sleep latency and induces daytime sleepiness and fatigue, and caffeine prolonges sleep latency and improves daytime sleepiness, fatigue, vigilance and attention in normal subjects. These results showed caffeine reverses alcohol's sedative and performance-disruptive effects.
