This study conducted the following experiment to examine effects of cardiovascular function on lumbar stabilization exercise(LSE) in floor or swiss ball. This experiment was conducted to compare heart rate, systolic blood pressure, diastolic blood pressure and peripheral vascular oxygen saturation effects by lumbar stabilization exercise in floor or swiss ball with 18 normal adult and it divided 9 subjects. experiment group (1) is applying LSE on floor group and (2) is applying LSE on swiss ball group. Heart rate was measured by portable heart rate manometer, blood pressure was measured by hemodynamometer, and peripheral vascular oxygen concentration was measured using a computerized NURYTEC measuring apparatus analysis. These result lead us to the conclusion that systolic blood pressure and peripheral vascular oxygen concentration were influenced by LSE. but there was not differential effect between each groups. These results suggest that LSE has the capability to improve heart rate, blood pressure, peripheral vascular oxygen concentration. Consequently, LSE would be lead to increment of cardiovascular function.

This study examines the effects of spasticity, equilibrium and gait ability at lower extremity on lumbar stabilization exercise(LSE) with Swiss ball. This experiment was conducted to compare BBS, FRT, MAS and TUG by Swiss ball LSE with 34 stroke patients. equilibrium by BBS or FRT, spasticity by MAS and gait ability by TUG were measured after a 8-week traditional exercise physical therapy(17 subject of stroke patient) and a Swiss ball LSE(17 subject of stroke patient). These result lead us to the conclusion that BBS & FRT were statistically increased and MAS and TUG were decreased on Swiss ball LSE group. there were statistically differential effect between each group on FRT and MAS. These results suggest that Swiss ball LSE has the capability to improve spasticity, equilibrium and gait ability at lower extremity. Consequently, Swiss ball LSE would be lead to restoration of muscle spasticity, equilibrium and gait ability on stroke patients.

Since Civil Law recognizes the freedom of a testament, it recognizes the freedom allowing the decedent to dispose his/her own property at his/her own intention. However, in order to prevent various abuses which may occur when the principle of freedom of testament is carried out unlimited, secured portion system is stipulated. So, absolute freedom of property disposed by the deceased is limited. Likewise, the secured portion system is introduced as the system to resolve the contradiction that exists between principle of freedom of testament and legal inheritance. Since Supreme Court Decision 2010DA50809 delivered on May 24, 2012 includes major legal issues such as how to exercise of claim of return for secured portions, transfer of the secured proportion or the claim of return for secured portions, and exercise of claim of return for secured portions against a third party. So, it has a very important meaning. In this paper, legal issues regarding the exercise of claim of return for secured portions have been reviewed with this decision.

The effects of Tabebuia avellanedae (Taheebo) on exercise endurance capacity were investigated using mice in an adjustable-current water pool. Compared to the control group, a 1.8~2.0 fold increase in swimming time was observed in mice administered hot water extract (TAW) and 80% ethanol extract (TAE) of inner bark from T. avellanedae. Blood lactate level, an important fatigue relevance factor, was significantly lower in the TAW and TAE groups than in the control group. The total phenolic contents of TAW and TAE were $93.3{\pm}1.6$ and $115.7{\pm}1.5mgGAE/g$, respectively. The levels of flavonoids in the extracts were $77.3{\pm}1.3$ and $95.9{\pm}1.7mgCE/g$, respectively. Higher antioxidant activities of TAE were observed in each assay at the same concentration as compared to TAW. Correlation between antioxidant activities of TAE with total polyphenol contents was observed. These results suggest that extracts of Taheebo increase exercise endurance capacity by elevating antioxidative potentials.
