This study proposes a construction method reinforcing with hybrid mortar using Ethylene-Vinyl Acetate Copolymer (EVA) used as an environmentally friendly noise reduction material in Korea and other countries, POSS nano complex (Polyhedral OligomericSilses-quioxaneS) and wire mesh. The final form of destruction, performance against force, strength, malleability were evaluated based on the flexural compression, a calculation equation of the slab reinforced with wire mesh and composite mortar was analyzed by comparing the values of the experiment and the values of the calculation equation proposed by existing theses.

This study conducted an experiment to verify the flexural reinforcement effect based on the state of damage by reinforcing damaged reinforced concrete slabs with hybrid mortar, in order to ascertain the effect of reinforcement construction methods verified to improve the strength of the structure and noise between floors on actual buildings. The method of experiment was conducted based on the “2017 Safety Inspection and Precise Safety Diagnosis Guidelines” of the Korea Infrastructure Safety and Technology Corporation, and the damage on the actual specimen was determination based on the displacement value occurring on the specimen.

The purpose of this study is to investigate prevents hypertension effect of ethanol extract of Sigesbeckia pubescens. In this study, to determine prevents hypertension effect of ethanol extract S. pubescens on suppression of calcium mobilization force in vascular smooth muscle cell line. Ethanol extract of S. pubescens,showed a moderate suppression of calcium mobilization force effect vascular smooth muscle cell line. Therefore, treatment with ethanol extract of S. pubescens may accelerate blood flow through dilatation of the blood vessel. This result suggest a potential role of ethanol extract of S. pubescens as source of prevents hypertension agent.
