Transfer in Third Language Acquisition
Ebru Turker 사단법인 한국언어학회 2017 언어학 Vol.0 No.79
This study analyzes second language transfer in third language acquisition. The L1 English participants were studying Korean either as an L2 (n = 23) or as an L3 (n = 22) after studying L2 Japanese. The study focuses on the Korean postpositions -ey, -eyse, and -(u)lo, which correspond to the Japanese postpositions -ni, -de, and -e. Beginning, intermediate, and advanced L2 and L3 Korean groups completed two tests (multiple choice and fill-in-the-blanks) in two particle use conditions (same vs. different in Japanese and Korean). Logistic mixed effects models found that both groups performed significantly better in the same than in the different particle use condition, indicating the influence of factors other than transfer. However, as proficiency increases, L3 learners performed better than L2 learners in the different particle use condition, suggesting different developmental trajectories. This finding implies that non-facilitative transfer can positively influence ultimate attainment.

A Quantitative Analysis of Anger and Happiness Metaphors in Korean across Genres and over Time
Ebru Turker 담화·인지언어학회 2022 담화와 인지 Vol.29 No.3
This quantitative study takes a data-driven corpus-based approach to variation in the use of Korean emotion metaphors across modern written genres and over time (1980–2004). It focuses on two sets of semantically close emotion words, hwa and pwunno (similar to anger and rage, respectively) in figurative expressions based on anger metaphors, and hayngpok and kippum (similar to happiness and joy, respectively) in figurative expressions based on happiness metaphors. The results demonstrate that both genre and year affect the frequency of occurrence of figurative expressions. For anger, hwa metaphors are more frequent in the nonfiction book and novel genres than other genres, while pwunno metaphors show no difference by genre. Hwa metaphors occur consistently and at high frequencies across the time period analyzed, while pwunno metaphors show up later and at lower frequencies. For happiness, kippum metaphors are more frequent in the nonfiction book and newspaper genres, while hayngpok occurs most frequently in the nonfiction book and novel genres. The frequency distributions of expressions with hayngpok and kippum changed over the years in different ways, with short, reversed rises and falls. The paper concludes by discussing the benefits and limitations of a corpus-based genre approach to the study of figurative language.

Korean adverbial particle -(u)lo , L2 acquisition, particle development process, L1 English learners
( Ebru Turker ) 한국문법교육학회 2017 문법 교육 Vol.31 No.-
This study investigates the acquisition of the multiple meanings of the Korean adverbial particle -(u)lo by L1 American English learners of Korean-as-a-foreign-language studying at U.S. institutions. Beginning, intermediate, and advanced proficiency level learners (N=45) participated in two types of tasks to determine their ability to interpret and produce six meanings of -(u)lo, to which they had been exposed in formal classroom settings. The results indicate different developmental trajectories with respect to different meanings of the particle. The findings of a statistical analysis show that only the transportation meaning of -(u)lo had been acquired by all levels. The intermediate level participants’ performance on the raw material, instrumental, and directional meanings was better than the beginning level participants’ performance, and the advanced level participants demonstrated nearly full acquisition of these four meanings (i.e. transportation, raw material, instrumental, and directional). All groups showed low rates of acquisition for the reason and option meanings. The study suggests that the acquisition and development of the meanings of -(u)lo are affected by cross-linguistic influence, semantic complexity, the availability of linguistic input, and the possibility of particle alternation.

PURPOSE. The aim of the present study was to investigate the effects of surface treatments on the bond strengths between polymer-containing restorative materials and two dual-cure resin cements. MATERIALS AND METHODS. In the present study, rectangular samples prepared from Lava Ultimate (LU) and Vita Enamic (VE) blocks were used. The specimen surfaces were treated using CoJet sandblasting, 50 ㎛ Al<sub>2</sub>O<sub>3</sub> sandblasting, % 9 HF (hydrofluoric) acid, ER,Cr:YSGG laser treatment, and Z-Prime. Dual-cure resin cements (TheraCem and 3M RelyX U 200) were applied on each specimen's treated surface. A micro-tensile device was used to evaluate shear bond strength. Statistical analysis was performed using the SAS 9.4v3. RESULTS. While the bond strength using TheraCem with LU or VE was not statistically significant (P=.164), the bond strength using U200 with VE was statistically significant (P=.006). In the TheraCem applied VE groups, Z-Prime and HF acid were statistically different from CoJet, Laser, and Sandblast groups. In comparison of TheraCem used LU group, there was a statistically significant difference between HF acid and other surface treatments. CONCLUSION. The bonding performance between the restorative materials and cements were material type-dependent and surface treatment had a large effect on the bond strength. Within the limitations of the study, the use of both U200 and TheraCem may be suggested if Z-prime was applied to intaglio surfaces of VE. The cementation of LU using TheraCem is suitable after HF acid conditioning of the restoration surfaces.
