Objective: The aim: To analyze the levels of competence formation in parents of senior preschoolers with moderate ID and to substantiate the obtained indicators for practical use.
Patients And Methods: Materials and methods: The sample of the study was 162 persons: experimental group (EG) - parents (or persons substituting them) of 53 preschoolers with moderate ID - 96 persons (out of the total number, 12 children are brought up by mothers without fathers); control group (CG) - parents (or persons substituting them) of 41 preschoolers with MID - 66 persons (out of the total number, 16 children are brought up by mothers without fathers).
Results: Results: The use of Fisher's φ-criterion allowed to draw the following conclusions: first, at the ascertaining stage of the experiment the characteristics of the EG and CG according to certain indicators of parental competence were homogeneous (α=0.
Ethonium, an antimicrobial chemotherapeutic agent, was investigated by mass spectrometry (MS) under various ionization conditions: electron impact, field ionization, field desorption (FD) and fast atom ionization. FDMS was found to be the most suitable procedure for ethonium identification. Relation of the ED mass spectra to the distance between the nitrogen atoms in bis-quaternary ammonium compounds is discussed.
