Objective: The aim of this study was to invastigate the validity and reliability of the Turkish version of the Professional Quality of Life Scale (ProQOL R-IV). Methods: One hundred health professionals participated in the study. All participants were assessed using the ProQOL R-IV, the Burnout Inventory and the Brief Symptom Inventory the Turkish versions. Results: A moderate correlation was observed between the Turkish Version of the ProQOL R-IV (and its subscales) and the Brief Symptom Inventory (and its subscales). The ProQOL R-IV was correlated with Burnout Inventory and Brief Symptom Inventory (respectively, r=0.391, p<.01, r=0.401, p<.01). The Cronbach's alpha value of the scale was 0.848. Conclusion: This study demonstrated that the Turkish version of the ProQOL R-IV is a valid and reliable instrument. It is assumed that the scale might be especially useful in the assessment of professionals in stressful working conditions and may provide the clinician with data contributory for the management of these subjects.

A two year field experiment was conducted in field conditions using wheat (Triticum aestivum ssp. Vulgare L. cv Bezostaja) as the test plant for the evaluation of phosphate solubilizing (+PS) microorganisms. Bacterial strains significantly (P<0.05) increased plant biomass (by 13 to 36 %) without plant P enrichment. Only Bacillus sp. #189 significantly (P<0.05) raised plant P-content, biomass and rhizosphere soil Olsen P at Zadoks Scale 62 simultaneously. Inoculations variably increased plant potassium (K-), magnesium (Mg-), zinc (Zn-), and managenese (Mn-) contents at harvest (Zadoks 92) but not earlier (Zadoks 31 and 61). The enrichment of the inoculated plants with nutrients other than P indicates the presence of alternative plant growth promoting mechanisms. This study showed that promising phosphate solubilizing microorganisms could increase not only the P content of the plants, but also the soil available P in rhizosphere transiently.
