Gerald Trutnau.In this thesis, we study an analytic approach to global well-posedness and long-time behavior for weak solutions to ItΓ΄-SDEs with rough coefficients. Using elliptic and parabolic regularity theory and generalized Dirichlet form theory, we show existence of a pre-invariant measure for a large class of elliptic second order partial differential operators and show that these are in fact infinitesimal generators of a Hunt process. Subsequently, this Hunt process is identified for every starting point as a weak solution to an ItΓ΄-SDE in R^d up to its explosion time. The Hunt process has continuous sample paths on the one-point compactification of R^d and by a known local well-posedness result, it is a pathwise unique and strong solution up to its explosion time to the SDE that it weakly solves. Using analytic and probabilistic methods, we derive general strong Feller properties, including the classical strong Feller property, Krylov type estimates, moment inequalities and various non-explosion criteria. Using a parabolic Harnack inequality, we show irreducibility and strict irreducibility of the process and derive explicit conditions for recurrence and ergodic behavior. Moreover, we investigate well-posedness of weak solutions to ItΓ΄-SDEs with degenerate and rough diffusion coefficients whose points of degeneracy form a set of Lebesegue measure zero. In the final part we consider the case where the pre-invariant density is explicitly given. In contrast to the previous case, where we only knew its existence with a certain regularity, we investigate how far our previous methods can be extended and applied in case of a non-degenerate, possibly non-symmetric and discontinuous diffusion matrix. For this, we develop some variational approach to regularity theory for linear parabolic PDEs involving divergence form operators with weight in the term where time derivative appear.μ΄ λ

[μλ¬Έ]Hearing disability is one of the highly manipulated diseases in present times that can be minimized or treated by producing an appropriate therapy in the possibly earliest period of time and, further providing them with an appropriate childhood special education.
This research has been conducted on all the babies born in 2000 with bilateral hearing loss. The cost of the fees was estimated by the government who has estimated educational fees and direct medical fees such as newborn hearing screening, cochlear implantation, operation during and after.
Based on the experiment on 2000, the researchers estimated that there were 494,625 newborn babies in total; however, 494.625 newborn babies had hearing loss, 24.73125 newborn babies had innate hearing loss and missed their annual hearing screen, and 49,413.03750 newborns had hearing loss and were diagnosed by a hearing screen. The estimated annual cost of being diagnosed with the hearing screen was 3,960,957,000 won, and with the cochlear implantation was 11,862,097,000 won. Furthermore, the tuition for education was estimated 61,836,257.67 won for each student with hearing disability in special education schools and 13,325,769.18 won for each student with hearing loss in general schools.
From these results, it is concluded that the estimated medical fee without hearing screen during the childbirth is 13,076,512,000 won, and the estimated education fee is 26,986,584,000 won (total 40,063,096,000 won). When the hearing screen is carried out for all newborn babies, the e! stimated amount of the medical fee is 18,493,760,000 won and the tuition is 14,449,457,00 won (total 32, 913,217,000 won).
Similar to other foreign countries, the medical fees will likely rise as we provide newborn hearing screens at birth, but the cost of educational fee will decrease and a reduced cost can be obtained from the result in return. Thus, just like other advanced countries, it is also necessary for Korea to give hearing screens to all the newborn babies.ope
