154 Conclusions and future work<br />
The issue <strong>of</strong> the sp<strong>at</strong>ial vari<strong>at</strong>ions <strong>of</strong> temper<strong>at</strong>ures and abundances across a given Hii<br />
region (or galaxy) is also one important po<strong>in</strong>t th<strong>at</strong> deserves deeper <strong>study</strong>. For this purpose,<br />
IFS has been revealed as a powerful tool, as seen <strong>in</strong> this work. More d<strong>at</strong>a us<strong>in</strong>g this young<br />
technique is needed to enlarge the sample.<br />
With the help <strong>of</strong> IFS, it is possible to detect and loc<strong>at</strong>e precisely, with two-dimensional<br />
<strong>in</strong>form<strong>at</strong>ion, the ioniz<strong>in</strong>g sources <strong>of</strong> a given region. Until the beg<strong>in</strong>n<strong>in</strong>g <strong>of</strong> the XXI century,<br />
we had only one dimensional photo-ioniz<strong>at</strong>ion codes (i.e. CLOUDY, Ferland et al., 1998) to<br />
modelize <strong>ionized</strong> <strong>regions</strong>. However, 3D tools (i.e. MOCASSIN, Ercolano et al., 2003) have<br />
recently emerge as a powerful tool to unveil the processes <strong>of</strong> planetary nebula or Hii <strong>regions</strong>.<br />
Due to its self-consistent tre<strong>at</strong>ment <strong>of</strong> asymmetries, density, chemical <strong>in</strong>homogeneities as<br />
diffuse radi<strong>at</strong>ion, one <strong>of</strong> our future goals is to use MOCASSIN to modelize <strong>in</strong> a realistic way<br />
Hii complexes.<br />
Regard<strong>in</strong>g stellar popul<strong>at</strong>ions <strong>in</strong> Hii <strong>galaxies</strong>, we are f<strong>in</strong>ish<strong>in</strong>g a project to <strong>study</strong> the<br />
properties <strong>of</strong> the brightest knots <strong>of</strong> star form<strong>at</strong>ion <strong>in</strong> the Hii <strong>galaxies</strong> studied by Hägele<br />
et al. (2006) and Hägele et al. (2008) us<strong>in</strong>g detailed photo-ioniz<strong>at</strong>ion models. In this way<br />
we <strong>study</strong> the properties <strong>of</strong> the ioniz<strong>in</strong>g stellar popul<strong>at</strong>ion, <strong>in</strong>clud<strong>in</strong>g the Wolf-Rayet stars<br />
follow<strong>in</strong>g the analysis methodology expla<strong>in</strong>ed <strong>in</strong> Pérez-Montero and Díaz (2007).
