2.- Galactic structure from starcount analyses. The thin disk, Intermediate Population II, and halo density distributions. Luminosity functions. The extent of the Galaxy.

3.- Age, kinematical and abundance analyses of the thin disk, Intermediate Population II and halo from deep surveys and tracer surveys. Rotational velocities, abundance distributions. The thin disk/IPII interface. Age distribution of open and globular clusters.

4.- Dual halo scenarios. The division of the halo globular clusters into "young" and "old" halo systems and implications for the formation of the "dual halo". The second parameter problem and "young" halo globular clusters.

5.- Accretion and the Galactic halo. Discovery of "moving groups" of halo stars and possible moving groups of globular clusters. The Sgr galaxy and its system of globulars. The Magellanic Stream and the recent discovery of a tidel star stream thereform and implications for the Galactic halo. Alignments of globular clusters and Galactic satellites. The origin of "young" and second parameter globular systems.

3.- Star clusters as a Test for Stellar Evolution.
Vittorio Castellani. Univ. of Pisa. Italy. 1.- Modeling the evolution of low mass stars: i)the role of fundamental physics;
