Turkish validation of the Parents' Beliefs about Children's Emotions Questionnaire
Anatolian Journal of Psychiatry, 2016Co-Authors: Sukran Kilic, Hatice KumandasAbstract:Objective: The present study is aimed to examine psychometrical properties of the Parents' Beliefs about Children's Emotions Questionnaire (PBACE) which is an important part of parental emotion socialization and closely related to children mental health, for Turkish parents and to detect measurement invariance according to parent gender. Methods: Three hundred and fifty mothers and 350 fathers who have children between the age of 4-10 participated in this study in Aksaray province. The PBACE is a Likert type Scale and consisting of 33 items. For its Turkish adaptation, translation and back-translation were completed, and then submitted to experts for content, semantic and conceptual equivalance. Confirmatory Factor Analysis (CFA) was performed for examining construct validity. Parents of gender-based measurement invariance structure were analyzed by calculating the configural, metric and scalar invariance. An evaluation of the reliability of the Scale was made using, internal consistency (Cronbach's alpha) coefficients, test-retest correlation methods and item-total correlation. Results: The validity of the data obtained from the measurement tool in the study were analyzed by examining the results of CFA. CFA results indicated that the questionnaire has a structure of seven factors and data model compliance was found to be within acceptable values. Internal consistency coefficients, test-retest values and item total correlations were examined and it was found that PBACE is a reliable measuring instrument. For parent gender measurement invariance fit indexes (Chi-square, RMSEA, SRMR, CF, TLI) in gradually obtained models was examined whether the range is acceptable. When examining structural analysis results for two different gender level, it was seen that metric and scalar invariance is achieved. Discussion: Parents can use Turkish version of PBCAE for evaluating children's positive and negative emotions and parents and the questionnaire can also be used in studies examining clinical, developmental and family systems.Copyright © 2017, Cukurova University, Faculty of Medicine.

FSKD (3) - Application of Fuzzy Relative Quality Performance Matrix on the Improvement of Critical to Quality Problems
2008 Fifth International Conference on Fuzzy Systems and Knowledge Discovery, 2008Co-Authors: K. S. Chen, T. W. ChenAbstract:The implementation of 6-sigma project consists of five well-known stages, that is, define, measure, analyze, improve and control. Among them, four have received much analysis and exploration by articles and scholars as well. While in the respect of definition, quite a few literatures have suggested that voice of customer (VOC) should be used as the core basis in improving the overall business performance. In collecting VOC, questionnaire has long been regarded as one of the most important tools. Whereas VOC is in nature fuzzy and non-quantitative, to which the mandatory dichotomy cannot seem to apply. To effectively collect genuine VOC, this paper tries to adopt fuzzy linguistic questionnaire (FLQ) instead of the conventional Likert-Type Scale. In presenting our definition of customerpsilas fuzzy valuation index and fuzzy satisfaction index, we have referred to the methods adopted by Y. H. Hung et al. (2003). Furthermore, a set of fuzzy relative quality performance matrix (FRQPM) will be suggested by combining relative competition matrix proposed by D. M. Lambert & A. Sharma (1990), to help businesses in defining, through objectively viewed VOC, CTQ problems, in the process of promoting the 6-sigma program.

one stop shop free breathing dynamic contrast enhanced magnetic resonance imaging of the kidney using iterative reconstruction and continuous golden angle radial sampling
Investigative Radiology, 2016Co-Authors: P Riffel, Frank G Zoellner, Johannes Budjan, Robert Grimm, Tobias K Block, Stefan O Schoenberg, Daniel HausmannAbstract:The purpose of the present study was to evaluate a recently introduced technique for free-breathing dynamic contrast-enhanced renal magnetic resonance imaging (MRI) applying a combination of radial k-space sampling, parallel imaging, and compressed sensing. The technique allows retrospective reconstruction of 2 motion-suppressed sets of images from the same acquisition: one with lower temporal resolution but improved image quality for subjective image analysis, and one with high temporal resolution for quantitative perfusion analysis.In this study, 25 patients underwent a kidney examination, including a prototypical fat-suppressed, golden-angle radial stack-of-stars T1-weighted 3-dimensional spoiled gradient-echo examination (GRASP) performed after contrast agent administration during free breathing. Images were reconstructed at temporal resolutions of 55 spokes per frame (6.2 seconds) and 13 spokes per frame (1.5 seconds). The GRASP images were evaluated by 2 blinded radiologists. First, the reconstructions with low temporal resolution underwent subjective image analysis: the radiologists assessed the best arterial phase and the best renal phase and rated image quality score for each patient on a 5-point Likert-Type Scale.In addition, the diagnostic confidence was rated according to a 3-point Likert-Type Scale. Similarly, respiratory motion artifacts and streak artifacts were rated according to a 3-point Likert-Type Scale.Then, the reconstructions with high temporal resolution were analyzed with a voxel-by-voxel deconvolution approach to determine the renal plasma flow, and the results were compared with values reported in previous literature.Reader 1 and reader 2 rated the overall image quality score for the best arterial phase and the best renal phase with a median image quality score of 4 (good image quality) for both phases, respectively. A high diagnostic confidence (median score of 3) was observed. There were no respiratory motion artifacts in any of the patients. Streak artifacts were present in all of the patients, but did not compromise diagnostic image quality.The estimated renal plasma flow was slightly higher (295 ± 78 mL/100 mL per minute) than reported in previous MRI-based studies, but also closer to the physiologically expected value.Dynamic, motion-suppressed contrast-enhanced renal MRI can be performed in high diagnostic quality during free breathing using a combination of golden-angle radial sampling, parallel imaging, and compressed sensing. Both morphologic and quantitative functional information can be acquired within a single acquisition.
