THE EFFECTS OF THE BIBLIOTHERAPY TECHNIQUE ON PERFECTIONISM LEVELS IN GIFTED CHILDREN: AN EXPERIMENTAL STUDY

Perfectionism is one of the personality traits of gifted children. When this trait, which may have positive or negative effects on the individual, is incorrectly handled by the child, it can cause problems such as anxiety and stress. The aim of this study was therefore to investigate the effects of bibliotherapy on perfectionism levels in gifted children. A total of 64 gifted children in the 3rd and 4th years of primary school (that is, children aged 9-10) took part in the study. The scale used to measure their perfectionism levels was the Multidimensional Perfectionism Scale (MPS) (Özbay & Mısırlı-Tasdemir, 2003), while the Reading Attitude Scale (RAS)(Ünal, 2006) was used to measure attitudes to reading. A random selection of 14 individuals whose scores were above the group average was identified for this study, in which the 2X2 experimental model was applied. Of these 14, 7 who had received high scores in RAS were placed in the experimental group, while another 7 of the same ages and genders were placed in the control group. When equivalence between the two groups had been obtained, the 7-session bibliotherapy-based training program was administered by the researcher to the experimental group. As a result of the study, it was found that the bibliotherapy training program thus applied reduced perfectionism levels to a significant degree. This reduction was found to be significant in terms of the following sub-scales of MPS: excessive concern over making mistakes, personal standards, doubting the quality of one’s actions and preference for order, and organization (but not in the dimension of parental criticism).  Article visualizations

Copolymers of 7-Methoxy-2-Acetyl Benzofuryl Methylmethacrylate with Styrene: Synthesis, Characterization, Reactivity Ratios and Determination of Kinetic Parameters with Thermogravimetric Analysis

The 7-methoxy-2-acetyl benzofuryl methylmethacrylate (MABMM) monomer was synthesized by reacting 7-methoxy-2-bromo acetyl benzofurane with sodium methacrylate in acetonitrile solvent at 70°C in the presence of triethylbenzylammoniumchloride (TEBAC). The monomer was characterized by FTIR, 1H-and 13C-NMR spectral studies. Reactivity ratios for the copolymers 7-methoxy-2-acetyl benzofuryl methylmethacrylate (MABMM)-co- styrene (ST) are reported. Copolymers were prepared by free radical polymerization using 2,2?-azobisisobutyronitrile (AIBN) as an initiator at 70°C in 1,4-dioxane solution. FTIR, 1H-and 13C-NMR spectral studies and gel permeation chromatography (GPC) were used the copolymer characterization. The monomer compositions in the copolymer were determined by elementel analyses and the reactivity ratios (ri) were calculated applying diverse linear methods, namely Finemann-Ross (FR) and Kelen-Tüdös (KT) and the nonlinear error invariable model method of a computer program RREVM. By using the latter pr°Cedure, the values of the reactivity ratios were estimated as 2.74 and 0.69 for the system MABMM (1) and ST (2), respectively. These values suggest the formation of nearly-alternating copolymers in the systems. Molecular weights were determined by gel permeation chromatography (GPC). The polydispersity indices of the polymers determined using suggest a strong tendency for chain termination by disproportionation. The glass transition temperature of the polymers were investigated by Shimadzu DSC-60 and the apparent thermal decomposition activation energies (Ed) were calculated by the Ozawa method using the Perkin-Elmer TGA thermobalance, respectively. Tg increases when the concentration of polar monomer (MABMM) in the copolymer increases. It was observed that thermal stabilities of copolymers increased with increasing of MABMM content in copolymers. © 2015 Copyright © 2015 Taylor & Francis Group, LLC.FUBAP-1352The authors wish to thank the financal support provided by the Fırat University Research Fund (Project No: FUBAP-1352).

Effects of extraction methods and conditions on bioactive compounds extracted from phaeodactylum tricornutum

The effect of homogenization, ultrasound and microwave extraction methods and conditions on fucoxanthin content, total phenolic content and antioxidant activity of extracts obtained from Phaeodactylum tricornutum were investigated in this study. The solvent/biomass ratio was the most effective parameter on fucoxanthin content, total phenolic content and antioxidant activity. The maximum fucoxanthin content (5.60 ± 0.06 mg/g) and antioxidant activity (763.00 ± 15.88 EC50 µg/mL extract) were obtained with the homogenization extraction method whose optimum conditions were 1.93% biomass/solvent ratio, ~5200 rpm homogenization rate and 14.2 min extraction time. Although the ultrasonic extraction method has reached the approximately same level of fucoxanthin content (5.24 ± 0.07 mg/g)), TPC (67.68 ± 1.58 mg gallic acid/L) and antioxidant activity (619.90 ± 17.16 EC50 µg/mL extract) at an amplitude of 55.72%, a higher biomass/ solvent ratio (2.72%) and a longer extraction time (17.37 min) have been required. The lowest fucoxanthin content, total phenolic content and antioxidant activity were determined for the microwave extraction method. © 2020 Slovensko Kemijsko Drustvo.
