Abstract Recent advances of ultrasound technology including 3D/4D sonography have revealed embryonal/fetal morphology, intrauterine vascularity and fetal behavior from early gestation. Modern ‘sonoembryology’ allows the definition of in vivo anatomy including visualization of dynamic features, which cannot be characterized in fixed specimens after embryonic death in embryology. Furthermore, recent highresolutional ultrasound technologies have remarkably approached accurate prenatal diagnoses with vivid and distinct sonographic depiction. Nowadays, the antenatal diagnosis is no longer ‘maybe’ nor ambiguous, owing to progressive 3D/4D ultrasound which have contributed to the field of embryology, fetal physiology and pathology.

Major Progress

The use CCD detectors has allowed a major progress in abundance derivations for globular cluster stars in the last years. Abundances deduced from high dispersion spectra now correlates well with other abundance indicators. I discuss some problems concerning the derivation of accurate metal abundances for globular clusters using high dispersion spectra from both the old photographic and the most recent CCD data. The discrepant low abundances found by Cohen (1980), from photographic material for M71 giants, are found to be due to the use of too high microturbulences.
