    In this study, a natural dye extraction was carried out to isolate dyestuff extract powder from the waste barks of Turkish red pine (Pinus brutia Ten.) timber which is not a common natural dyestuff source. The natural dyestuff powder obtained was applied to cotton, flax, wool, silk, tencel, polyamide and acrylic fibers accompanied by simultaneous application of alum and natural oak ash mordants. Color properties were investigated including rub-, light- and wash-fastness performance. Differently dyed fiber samples exhibited slightly different shades of beige, brown and brownish-yellow depending on the mordant used and fiber type. Alum mordanted samples exhibited better color properties. The highest (63.4) and the second highest (45.3) f(k) color yield values were observed for alum mordanted silk and wool samples, respectively. Dyed fabrics showed excellent wash fastness, very low staining performance, and moderate light- and rub-fastness. © 2013 The Korean Fiber Society and Springer Science+Business Media Dordrecht

    Key instructional design issues in a cellular phone-based mobile learning project

    Adding flexibility to the learning process, mobile learning offers great opportunities for education, especially for teenagers, who show great attentiveness to mobile technologies. Thus, the need to focus on design aspects of such learning is growing. This study aims to reveal critical issues in designing mobile learning based on a program for 11th graders and to unfold students' perceptions about reasons for participation, satisfaction, implementation processes, and specific content representation types. Reflections on insights gleaned from the instructional design process of the project and students' perceptions are presented with related recommendations

    Purpose: The aim of our research was to investigate the effect of multimodal aerobic, resistance and flexibility exercise training program on cardiovascular disease risk factor related with exercise capacity, lipid profile, flexibility, body composition, and glycemic control in newly diagnosed type 2 diabetic patients.\ud Material and Method: Sixteen newly diagnosed type 2 diabetes patients including 6 study subjects and 10 controls were enrolled in the study. Study group attended to exercise program for a period of 12 weeks. Body composition, flexibility, aerobic capacity, lipid profile, fasting blood glucose (FBG), postprandial glucose (PPG), and hemoglobin A1c (HbA1c) levels were assessed in all participants.\ud Results: Body fat decreased, flexibility, which was assessed using the sit and reach test, and aerobic capacity increased after the exercise program, these variables showed statistically significant difference within the groups (p<0.05). Triglyceride cholesterol and postprandial glucose levels showed statistically significantly decrease after the exercise program in all participants (p<0.05). Only post exercise FBG and hemoglobin A1c levels showed statistically significant difference between exercise and control groups (p<0.05). Additionally, the Borg Scale significantly positively correlated with FBG (r=0.63, p=0.09), PPG (r=0.51, p=0.039), and HbA1c (r=0.59, p=0.014).\ud Discussion: Twelve-week multimodal exercise training program improved the aerobic capacity and flexibility and decreased the cardiovascular disease risk related glycemic control by controlling body fat and triglycerides and by maintaining FBG and HbA1c below certain values.
