Objective: The aim of this study is to investigate the effects of whole body vibratory stimulation on muscle strength, balance, and fall efficacy among super-aged women. Design: Randomized controlled trial. Methods: Twenty-eight super-aged women over 80 years of age were assigned to either the experimental group (n=14) and control group (n=14). The experimental group received an exercise program that used the whole body vibratory stimulation with a frequency of 30 Hz and amplitude of 3 mm, and the control group received an exercise program without vibratory stimulation. Intervention was provided for 4 weeks, 3 sessions per week, and 30 minutes per session. In order to measure lower extremity muscle strength the 30-second chair stand test (CST) was used. The Berg Balance Scale (BBS) was used to measure dynamic balance. Static balance was measured by tracking the path length, velocity, and area of the center of pressure (CoP). The Falls Efficacy Scale (FES) was used to measure the subjects' fear of falling. Results: Both the experimental and control group demonstrated statistically significant increase in muscle strength, dynamic balance, and fall efficacy (p<0.05). Only the experimental group showed significant improvements in static balance before and after the intervention (p<0.05). The experimental group showed significantly greater improvements in CST, BBS, and CoP (path length, velocity) than control group (p<0.05). Conclusions: Whole body vibratory stimulation exercise is shown to be a safe and appropriate physical therapy intervention method to enhance muscle strength, balance, and fall efficacy of super-aged women.

Sarcoma is rare malignant tumor originated from mesenchymal stem cells that can differentiate to soft tissue and bone. Therefore sarcoma can be arised from any regions in human body. However, the incidence of bile duct sarcoma is extremely rare in adults. Obstructive jaundice is the most common presentation in the patients, but there`re no specific symptoms or signs. Also it can be misdiagnosed with other tumors or benign lesions in computed tomography or ultrasonography. For these reasons, it is hard to diagnose and manage. We present a case of intrahepatic bile duct sarcoma misdiagnosed with liver abscess in 70 year-old female with literature review.

본 논문에서는 유한요소법을 이용하여 차량용 One Touch Clamp 의 개발에 관하여 연구하였다. 유한요소법을 이용한 해석을 진행하기에 앞서 One Touch Clamp 의 모델링을 하였고, 인장 실험을 통하여 One Touch Clamp 의 물성치를 얻어 이를 바탕으로 유한요소법을 이용하여 응력분포도 확인으로 Clamp 의 안정성을 확보하였다. 또한 실제 차량의 주행조건과 동일한 조건에서 Clamp 의 조임력을 통한 누수 압력을 검토하여 Clamp 에 Leak 의 발생여부 및 누수여부를 확인하여 Cla,p 의 이상유무를 판단하여 개발을 진행하였다.

Objectives : Zizyphus jujuba fruits(ZJF), a traditional Korean medicine has various biological activities such as anti-inflammatory, anti-oxidative and neuro-protective effects. However, it is still unclear whether ZJF has any biological effect on anti-aging. In this study, we examined the effect of ZJF on lifespan and thermal stress in C. elegans. Methods and Results : ZJF water extracts were fermented for 7 days(F7-ZJF) and 14 days(F14-ZJF) by Laetiporus sulphureus to increase secondary metabolites such as aglycone of flavonoids and terpenoids. In the lifespan assay, ZJF water extracts and fermented ZJF were treated on the agar medium plate with age synchronized egg stage of C. elegans. Treatment of F7-ZJF-200 μg/mL with OP-50 E. coli and F14-ZJF-200 μg/mL with OP-50 E. coli significantly increased life span of C. elegans(N2) at thermal stress condition of 25℃. Moreover mRNA levels of lifespan associated HSP 16.1, HSP 70, and HSF-1 were increased at thermal stress condition of 25℃. However, in the equilibration temperature of 20℃ after stress condition of 35℃ for 2 hr, F-14-ZJF-200 μg/mL treatment decreased the levels of heat shock protein in hsp16.2/GFP C. elegans. Conclusions : Our study indicates that prolong role of fermented-ZJF in C. elegans is mediated by control HSPs production.
