    The Forgotten Roles and New Roles of Output in Second Language Acquisition

    변진석 | 2010, 5(6) | pp.51~64 | number of Cited : 0
    Abstract PDF
    For the past two and a half decades the roles of output in second language acquisition (SLA) have been discussed in many ways in the framework of the output hypothesis proposed by Swain (1985). However, some roles of output proposed in the early version of output hypothesis have not been investigated enough though they may play important roles in SLA. In addition, recent literature in SLA suggests that there may be some roles of output that have not been investigated so far. Therefore, this paper overviews the roles of output proposed in the early and the recent versions of output hypothesis and discusses the roles that need to be revisited and those that need to be investigated in the current SLA.

    French Influence on Learning English Lexical Stress by French Learners of English

    재스민 혜슉 , Tae-Jin Yoon | 2010, 5(6) | pp.75~84 | number of Cited : 0
    Abstract PDF
    Lexical stress in English plays an important role in native speakers’ perception and processing of speech. However, French learners of English have a fixed, final-stress system which differs from the free, variable-stress system of English. This difference in stress systems between the two languages may result in interference by the native language stress system in the production of English stress by French learners of English. This experiment sets out to test the hypothesis of native language interference in stress production. One female native English speaker and one female French learner of English produced 50 initially-stressed, trisyllabic English words (balanced for word frequency) twice in a carrier phrase ‘I didn’t say __but you said __ yesterday.’ A 2 (language) × 3 (syllable position) repeated-measures ANOVA was conducted on the data for each parameter of stress: fundamental frequency, amplitude and duration. The results supported the hypothesis of native language interference for the French learner of English. Implications of further work on second language acquisition and pedagogy were discussed.

    3D Point Set Rendering for iPhone

    SUN-JEONG KIM | 2010, 5(6) | pp.262~268 | number of Cited : 1
    Abstract PDF
    In this paper, 3D point set rendering algorithm is adapted to iPhone. Recent advances in scanning technology have led to a rapid increase in the availability and size of geometric data set. Instead of reconstructing a 3D mesh from a given point set, directly rendering it is very efficient in the running-time and space requirement. In addition, the smart phones such as iPhone have the advantage of rendering a point set because they may have not enough resources to display a 3D mesh whose size is bigger than the size of a point set representation. This paper introduces the rendering scheme of a 3D point set using OpenGL ES 2.0 in iPhone4. Shader techniques in OpenGL ES 2.0 enables to obtain the high-quality results of 3D point set rendering in the smart phones.
