A Crescent shaped prominence Structure (CS), over the solar west limb isstudied using EIS/HINODE and AIA/SDO. First, the time varying positions of thetop and below borders of the CS, along with its central axis are derived. Timeevolutions of the Doppler shifts, and Line width of Fe~{\scriptsize \rm XII}195.119 line are studied over the CS borders. Transverse kink oscillations areobserved both in the Solar-Y direction and in the Doppler shifts over theobservers' LOS. One explanation could be the oscillatory direction of the mainkink wave build an angle with the observers LOS. This angle is calculated to beequal to 27 degrees for the CS top border. The main kink amplitude velocity andperiods are obtained to be 5.3 $\rm km/s$, and 33.4 minutes, respectively. Theanti-correlation observed between the brightness and thickness of the CS (with-178.1$^\circ$) suggests the presence of sausage modes with periods of 20.8minutes. Based on the AIA imaging, it is suggested that the occurred jets andtheir afterward dimming are responsible to trigger the sausage mode. Theaverage electron densities of the CS over the time of the study is obtained tobe log($\rm n_e$)=9.3$\rm [cm^{-3}]$. The Alfv\'en velocity, magnetic field,and energy flux of the observed fast kink mode over the CS are estimated to be16.7 $\rm km/s$, 2.79 $\rm G$, 41.93 $\rm W/m^2$. Considering the magnetic fluxconservation inside the CS, expanding the CS cross section, causes the magneticfield to decay with the rate of $\rm 4.95 \times 10^{-4} \, G/sec$.
