Do Student Preferences for Different Types of Writing Affect Writing Improvement?
Roo, Young-Sook 팬코리아영어교육학회 2005 영어교육연구 Vol.17 No.3
This study investigates student preferences for and the effects of three different types of writing: free journal writing in class, sentence translation writing in class, and one-paragraph formal writing done at home. Three research questions guided this study: What type of writing task do Korean English as a Foreign Language (EFL) writers prefer? Is there any significant difference in improvement related to an individual’s preference for a particular type of writing? Is there any significant difference in improvement in accuracy among the three different writing tasks? Most of the students attending the writing class preferred the translation task because they were able to learn expressions and grammar rules explicitly. All the participants (twelve students) made improvement in accuracy in translation task regardless of their preferences. Four students were selected for data analysis and two of them showed improvement in the type of writing they preferred. The results suggest that teachers should consider student preferences for a certain type of writing when selecting writing tasks.
Poster Presentations : P6 ; Dissolving Microneedle Patch for Wrinkle Treatment
( Mi Roo Kim ),( Hui Suk Yang ),( Hyo Jung Kim ),( Hyung Il Jung ) 한국피부장벽학회 2013 한국피부장벽학회지 Vol.15 No.2
Current wrinkle treatment, which are based on topical application, have relatively low efficacy compared to injection treatment caused by lower skin penetration efficacy. Invasive therapies show superior wrinkle improvement, however there are side effects such as pain, infection, and inflammation. The aim of this study is to assess wrinkle improvement and safety of a novel cosmetic dissolving microneedle patches. Clinical studies were performed on 24 Korean women for 12 weeks. Patients in group A were treated with retinyl retinoate-loaded dissolving microneedle patches on the left eye crow`s feet area, and patients in group B were treated with ascorbic acid-loaded patches on the right eye crow`s feet area twice daily. Wrinkle improvement was evaluated by skin Visiometer SV 600. Both the retinyl retinoate- and ascorbic acid-loaded dissolving microneedle patches demonstrated statistically significant differences in all Visiometer R-values (P < 0.05). Also, there were no side effects such as allergic or irritant contact dermatitis. In conclusion, we developed novel cosmetic microneedle patches using retinyl retinoate and ascorbic acid and verified their safety and efficacy in wrinkle improvement. Various functional anti-aging agents could be formulated into dissolving microneedle patches regardless of their chemical properties, especially hydrophilicity. These cosmetic patches can be used efficiently in cosmetics given their patient usability, safety, and efficacy in wrinkle improvement.
