Korean-Speaking L2 Learners’ Understanding of Ambiguous Sentences with the Preverbal Also
김소영 언어과학회 2022 언어과학연구 Vol.- No.100
A sentence containing preverbal also (i.e., Mary also ate a cookie) causes semantic ambiguity since the focus is assigned to a subject NP or an object NP. Depending on which constituent is identified as focus, the sentence evokes a different presupposition in discourse contexts. The current study examined which interpretation Korean EFL learners prefer to have in the comprehension of preverbal also-sentences with ambiguous focus and how it can differ in terms of their English proficiency. In a revised picture truth value judgment task, participants were asked to read a target sentence and then view a picture that described a presuppositional event. They were asked to check whether the target sentence is compatible with the depicted situation. The results showed that low and intermediate proficiency groups favored an object-focused interpretation whereas groups of high proficiency and English native speakers were able to assign the focus to a subject NP and an object NP by making use of relevant presuppositions from picture contexts.
Factors influencing the emissions of aldehydes from plant species of the Korean peninsula
김소영 한국대기환경학회 2023 Asian Journal of Atmospheric Environment (AJAE) Vol.17 No.1
This study present the factors controlling the aldehyde emission (formaldehyde, acetaldehyde, propionaldehyde, etc.) from plant species such as Pinus densiflora, Pinus koraiensis, Quercus acutissima, Quercus variabilis, Ginkgo biloba, and Oryza sativa. Even in the same tree species illustrate the emission rate variation of as much as 30 ~ 40%. The β-value, a parameter quantifying the temperature and emission correlation, were assessed as 0.07, 0.05 for formaldehyde and acetaldehyde, respectively. The coefficient of correlation was 0.4 and 0.5. for Quercus variabilis. In addition, the correlation between PAR (photosynthetically active radiation) and the emission is assessed close to the temperature impact on the emission. The emission of formaldehyde and acetaldehyde from P. densiflora, P. koraiensis, and Q. variabilis also depends on temperature and PAR. The ERs of total aldehydes of P. koraiensis are assessed at the level of 357.2 ng gdw− 1 h− 1, followed by propionaldehyde (110.6 ng gdw− 1 h− 1), acetaldehyde (102.5 ng gdw− 1 h− 1), and formaldehyde (73.66 ng gdw− 1 h− 1).
