As the security of personal information is becoming more important in mobile phones, we are starting to apply iris recognition technology to these devices. In conventional iris recognition, magnified iris images are required. For that, it has been necessary to use large magnified zoom & focus lens camera to capture images, but due to the requirement about low size and cost of mobile phones, the zoom & focus lens are difficult to be used. However, with rapid developments and multimedia convergence trends in mobile phones, more and more companies have built mega-pixel cameras into their mobile phones. These devices make it possible to capture a magnified iris image without zoom & focus lens. Although facial images are captured far away from the user using a mega-pixel camera, the captured iris region possesses sufficient pixel information for iris recognition. However, in this case, the eye region should be detected for accurate iris recognition in facial images. So, we propose a new fast iris detection method, which is appropriate for mobile phones based on corneal specular reflection. To detect specular reflection robustly, we propose the theoretical background of estimating the size and brightness of specular reflection based on eye, camera and illuminator models. In addition, we use the successive On/Off scheme of the illuminator to detect the optical/motion blurring and sunlight effect on input image. Experimental results show that total processing time(detecting iris region) is on average 65ms on a Samsung SCH-S2300 (with 150MHz ARM 9 CPU) mobile phone. The rate of correct iris detection is 99% (about indoor images) and 98.5% (about outdoor images).

This study analyzed the TV documentary titled on early childhood English education through narrative structure analysis (Chatman, 2003). It performed syntagmatic analysis to clarify the story structure with a focus on the development of events, and paradigmatic analysis to understand the semantic structure hidden in the text by binary opposition analysis. The documentary was constructed in the frame of 'balance-confusion-rebalance', and it was explicitly delivered that the English immersion education prohibited in the private elementary schools has stimulated the market of private English education. However, the government's and students' voices were missing, and the group of parents, private elementary school officials, and people involved in private English institutes played as main agents to lead the discourse of English immersion and early childhood English education in the documentary.

Online education is a new domain of learning that combines distance learning with the practice of face-to-face instruction utilizing computer-mediated communication. As technology continues to develop and the needs of teachers require better access to higher learning, online graduate degree programs can be a valid alternative. Some institutions in the United States have already offered graduate degrees in music education through the online distance learning. In this study, 8 accredited online graduate degree programs in music education were identified in terms of curriculum requirement, program requirement, and admission requirement. Online programs offer considerable benefits of convenience, while their drawbacks relates to the quality of learning, feelings of weaker interpersonal interaction. More researches need in order for online music programmers to achieve higher standards of instruction and to inform other disciplines in the fields of arts education and the performing arts.
