Crossing Cultures and Genres: The Voices of Heaven, Poetry, and Comfort Women of WWII
No full textMaija Rhee Devine loved literature and earned a Master’s in English. But she resisted for 25 years her husband’s encouragement to write about her life, a story that starts with her as an infant being given away by her biological family while they kept her twin brother. Once she began writing, The Voices of Heaven and her poetry book Long Walks on Short Days were published. She discusses the culture and history of South Korea that shaped her writing--the effects of patriarchy in all aspects of Korean life, gender and population imbalance issues, the impact of the Korean War, and the future of South and North Korea relations. She also talks about her works-in-progress on Comfort Women of WWII, all stories of the past keeping powerful rein on the present and future.Maija Rhee Devine responds to questions from Armando F. Sanchez, a producer of international digital education programs, about the start of her unintended writing career; the metamorphosis of The Voices of Heaven from a memoir to a novel; and poetry, nonfiction, and fiction writing on topics including Comfort Women of WWII. Into the dialogue, she weaves aspects of South Korean life as they relate to patriarchy, gender inequality, and the future of North and South Korea relations. Why write? To journey with readers through the tombs of human suffering and witness characters standing, powered by empathy and dignity

Keratin fibres recovered from tannery industry wastes as fire retardant agents on PLA composites
No full textAs it is well known, tannery leather process is a high pollutant emissor. During beamhouse stage, the wastes have a strong negative environmental impact because of the effluents and solids have a high content of organic matter. Hair skin derived from this stage, which is thrown in sanitary fills without any usual treatment. However, wasted hair is considered an important keratin fibre source with interesting applications in polymer materials. In this work keratin fibres (KFs) were recovered from tannery industry wastes [1]. A specific treatment was applied to KFs in order to obtain polymer composites base on PLA, KFs and aluminium tri-hydroxide (ATH) by extrusion process. The effect of KF content and the joint action of KFs in combination with ATH as fire retardant for poly(lactic acid) -PLA- was studied by thermogravimetric analyses, UL94 classification, dynamical-mechanical, mechanical and rheological analysis. According to collected data, the fire retardant potential of keratin fibres recovered from tannery industry wastes on PLA composites have been demonstrated. Following UL94 classification PLA composites were classified as V2 rating with only KFs (3, 5 and 10 phr). However, when KFs were added to 30 phr ATH, the composites reached V0 rating, the same classification obtained using 50 phr ATH. Therefore, by using low KF content (3 phr), it is possible to replace 20 phr ATH. In addition, KF-based composites exhibited higher mechanical properties than that containing only ATH. Flow behaviour under continuous simple and small amplitude oscillatory shear flows demonstrated that KFs decrease the viscosity of the PLA composites in a remarkable way improving the processability of PLA composites. Materials containing both KFs and ATH exhibited a higher elastic behaviour than those loaded with only KFs. The latter result represents an important advantage from an economical and environmental point of view in flame retarded materials.
