An approximate solution of the d.d.mensional Schrod.nger equation with the mod.fied.Posehl-Teller potential is obtained.with an approximation of the centrifugal term. Solution to the correspond.ng hyper-rad.al equation is given using the conventional Nikiforov-Uvarov method. The normalization constants for the Poschl-Teller potential are also computed. The expectation values of 〈r^-2 and.〈V（r）〉 are also obtained.using the Feynman- Hellmann theorem.

Two basic motivations for an upgrad.d.JLab facility are the need.： to d.termine the essential nature of light-quark confinement and.d.namical chiral symmetry breaking （d.SB）; and.to und.rstand.nucleon structure and.spectroscopy in terms of Qcd.s elementary d.grees of freed.m. d.ring the next ten years a programme of experiment and.theory will be cond.cted.that can ad.ress these questions. We present a d.son- Schwinger equation perspective on this effort with numerous illustrations, amongst them： an interpretation of string^breaking; a symmetry-preserving truncation for mesons; the nucleon＇s strangeness σ-term; and.the neutron＇s charge d.stribution.

d.e to the rapid.growth of the mining sector of Mongolia, the need.for preparing mining surveying specialists is increasing significantly. The history of preparing highly ed.cated.mining surveying specialists and.putting their ed.cation into practice in our country is an interesting one. The main center to prepare mining surveying specialists is the School of Mining Engineering of the Mongolian State University of Science and.Technology. This paper introd.ces the work that is being d.ne tod.y to prepare mining surveying specialists in Mongolia and.its future purposes.

Parton d.stribution functions (d.s) have long been recognized.as key measures of had.on structure. Tod.y, theoretical pred.ction of such d.s is becoming possible using d.verse method. for continuum and.lattice analyses of strong interaction (Qcd. matrix elements. Recent d.velopments includ. a d.monstration that continuum and.lattice analyses yield.mutually consistent results for all pion d.s, with behavior on the far valence d.main of light-front momentum fraction that matches Qcd.expectations. Theory is also d.livering an und.rstand.ng of the d.stributions of proton mass and.spin amongst its constituents, which varies, of course, with the resolving scale of the measuring probe. Aspects of the pion d. and.proton spin d.velopments are sketched.herein, along with some novel perspectives on gluon and.quark orbital angular momentum.
