Abstract: Respiratory diseases, which are caused by viruses and bacteria affect the upper and lower respiratory tract, are a leading cause of morbidity and mortality globally, accounting for approximately 5.8 million deaths worldwide. This study attempts to document some of the most selected medicinal plants found in the study area with respect to respiratory diseases infections. The study was conducted in Yem special woreda of which three kebeles namely (Angery, Kerewa, and shemona metelo). The kebeles were selected purposely based availability of medicinal plants. This study recorded more than 31 plant-derived medicines to cure various respiratory diseases and also corona virus-related diseases. Other questionnaire based results revealed that almost all 90 (98.9%) of the respondents know the causative agents of respiratory diseases. Majority of the communities 43 (86.8%) want to transfer their traditional knowledge to everyone and their source of knowledge for traditional healing is from their father, whereas 11 (12.1%) of them from their mother, 6 (6.6%) from their grandmother and father and 3 (3.3%). Thus, the government should strengthen the capacity of traditional healers with training, financial support and improve means of protecting their intellectual property rights. Moreover, detailed study on phytochemical analysis of these medicinal plants should be promoted so as to modernize the effort of these traditional healers.

Abstract: Earthquake is a most disaster event, responsible a lot of structural damage and casualties worldwide on the earth’s surface without any early warning. The trends in using dampers in buildings and tall buildings, increasing yearly based on their outstanding feature during an earthquake event. Typically, there are four types of energy dissipation device system such as friction damper, viscous damper, viscoelastic damper and metallic damper. The theoretical and experimental study results indicate that all fourth types of dampers can be able to minimize the structural damages and cracking during an earthquake occurrence event. But only viscous damper device has an acceptable feature against of earthquake forces as compare to other kinds of damper devices in symmetric and asymmetric building plan configurations as well. Based on the reviews, a viscous damper device system plays major role in reducing the lateral displacement of buildings about 30% to 85%, inter-storey drift of building about 60% to 80% and 1487.82KN drop in base shear of structural components in symmetric and asymmetric building plan configurations upward as compared to friction dampers, viscoelastic dampers and metallic dampers. Contradictory, dampers can decrease the construction cost limitation of multi-storey structures economically rather than conventional buildings.
