This study investigates the effects of corpus-based vocabulary tasks on the acquisition of English vocabulary in an attempt to explore the influence of corpus use on EFL pedagogy. For this to be realized, a total of 40 Korean high school students participated in the study over a 4-week period. An experimental group used a set of corpus-based tasks for vocabulary learning, whereas a control group carried out a traditional task (i.e., the L1-L2 translation) for vocabulary learning. To assess learning gains, the students were asked to complete the pre- and post-treatment tests measuring the word form, meaning, and use aspects of target lexical items. Results of the study indicate that in the experimental group the corpus-based vocabulary tasks were beneficial for the learning of word forms and use. In particular, corpus-based benefits were greatest in the low-proficiency EFL learners' collocational aspects of vocabulary use. On the other hand, in the control group, the traditional vocabulary tasks benefited the meaning aspects of target vocabulary items the most. In addition, survey results revealed that most students were positive about the corpus-based learning experience although some expressed reservations about the heavy cognitive load and the time-consuming nature of the analysis of corpus data primarily due to learners' lack of language proficiency.

This study aims to uncover the learner's language proficiency shown in the writing data of Chinese elementary/intermediate level learners. Language proficiency of the learners acquired by error analysis provides only partial information, and thus this study analyses the interlanguage of Korean learners in terms of 'Mean Length of Utterance, MLU' to discover the overall aspect of learner's language proficiency more symmetrically. The analysis of vocabulary area is to be enforced after generally studying the learner's language development aspect in accordance with MLU-m(orpheme) and MLU-(w)ord found in compositions by Chinese speaking Korean language learners. In terms of MLU, it has been slightly increased as the level of proficiency between elementary level and intermediate level learners; however, the morpheme seemed to be difficult to use, since the difference between Chinese learners and Korean university students has been notably shown. Vocabulary diversity, using aspect for each word class, and using aspect of the predicate are studied for vocabulary area; more various and numerous vocabulary tend to be used as the level of proficiency increases. In terms of predicate use, Chinese learners use less numerous vocabulary types.

This study aims to explore a new technique making complementary linkage between controlled vocabularies and uncontrolled vocabularies for analyzing a research domain. Co-word analysis can be largely divided into two based on the types of vocabulary used: controlled and uncontrolled. In the case of using controlled vocabulary, data sparseness and indexer effect are inherent drawbacks. On the other case, word selection by the author's perspective and word ambiguity. To complement each other, we suggest a descriptor profiling that represents descriptors(controlled vocabulary) as the co-occurrence with words from the text(uncontrolled vocabulary). Applying the profiling to the domain of information science implies that this method can complement each other by reducing the inherent shortcoming of the controlled and uncontrolled vocabulary.

This paper aims to explore the vocabulary difference between South and North Korean English textbooks as a first step toward a unified vocabulary list. To this end, both South and North Korean English textbooks in 2000s and 2010s are digitized into a corpus of text files, and a vocabulary list is constructed based on the corpus with reference to its concordances for the vocabulary use and contexts using AntConc 3.5.7. The vocabulary list of North Korean English textbooks are compared and found in their differences of quantity and quality of the English vocabulary in English education. Both quantitative and qualitative differences are found in between South and North Korean English textbook corpus. Both South and North aim that students learn about 3,000 words throughout the English education. North Korean English textbook contains more special academic vocabulary while South Korean English textbook is constrained by a strict vocabulary control which does not allow such a flexibility. Differences of vocabulary and their use are caused by the capitalistic market economy of South and the socialists' planned economy of North. Differences are also attributed to the religious words and grammatical vocabulary appearance.

While noticing that there is insufficient interest in the assessment of EFL learners' vocabulary levels or sizes, the researchers developed two tests identical in form (Forms A and B) to assess the lexical knowledge of Korean university learners at the $1^{st}{\sim}10^{th}$ 1,000 word bands by adapting a pre-established vocabulary levels test (VLT). Of equal concern was to investigate if the VLT was equally a valid and reliable instrument to be used on measuring the lexical knowledge of EFL learners. The participants were 804 university freshmen enrolled in a General Education English Course from four different colleges. The learners were asked to respond to either Form A or B. While scores generally fell towards the lower frequency bands, multiple regression found the Korean College Scholastic Ability Test (CSAT) to be a significant variable for predicting the learners' vocabulary sizes. From a methodological perspective, however, noticeable differences between Forms A and B could be found with item response theory analysis. The findings of the study provide suggestions on how future VLT for testing EFL learners may have to be redesigned.

The purpose of this study was to investigate the relationship of toddlers' vocabulary ability with reading activities and teachers' verbal and nonverbal behaviors during book reading. The subjects were 52 teachers and 104 toddlers at age 2. Lee and Kim (2004)'s categories of the Teachers' Verbal Behaviors, the categories of the Nonverbal Behavioral Analysis(Kim. 2005), and the Peabody Picture Vocabulary Test-Revised (Kim, et al.1995) were used. The data was analyzed by t-test, ANOVA, and Correlations. The results indicated that there were significant correlations in the subcategories of reading activities in classrooms, teachers' picture book reading behaviors, and toddler's vocabulary ability. The toddler's vocabulary ability increased as the 'interacting time both before and after book reading' became longer. The toddler's vocabulary ability increased as 'connecting with previous experience', 'asking questions for confirmation', 'acknowledging,' and 'expanding' of verbal behavior, as well as the nonverbal behavior, such as 'requesting behavior', 'emotional contact,' and 'empathetic behavior.' In conclusion, teachers' reading behaviors and activities were related to toddlers' vocabulary ability.

Objective: The purpose of this study is to identify the longitudinal reciprocal relationship between young children's vocabulary ability and physical aggression in young children. Methods: Two waves of panel data(2013/2015) from the Panel Study of Korean Children were analyzed in this study by using an adapted version of Autoregressive cross-lagged modeling. A total of 306 five-year-old and seven-year-old preschoolers, and their mothers participated in the study. Autoregressive cross-lagged modeling for multiple groups was conducted by using AMOS 24.0. Results: First, vocabulary ability and physical aggression showed stability over time. Second, young children's vocabulary ability(t) had a statistically significant effect on physical aggression(t+1). Conclusion/Implications: This study confirmed the interrelationships of young children's vocabulary ability and physical aggression by examining longitudinal data using the longitudinal analysis method. This study highlights the importance of developing interventions to support language development with aggressive children. The results of the present study can be used as a source in developing policies for aggressive children and their parents.

This study analyzed the vocabulary level in the 'Water' unit of chemistry I textbook. It also analyzed its relevance to the 11th graders' vocabulary level. The main tool for analyzing vocabulary level was SWA(Science Word Analysis) program which was referenced the Standard Korean Dictionary and Graduated Vocabulary of Korean Language Education. The results in this study turned out to be as follows: The distribution of scientific vocabulary level increased from Level-1 to Level-3 and showed a tendency to decrease from Level-3 until Level-5. The average percentage of Out of level is the largest as 37%. The highest percentage of non-scientific vocabulary was Level-1. The distribution of non-scientific vocabulary level decreased progressively. The Level-5 and Out of level are used 18% averagely. So, there are 6 vocabularies of Level-5 and 82 vocabularies of extra-level inappropriate in scientific vocabularies. And there are 53 vocabularies of Level-5 and 145 vocabularies of Out of level inappropriate in non-scientific vocabularies. Therefore, the overall state of textbooks for grade 11 students are reasonable. But there are a great many vocabularies inappropriate for them. Those should be used minimum, and to be changed to the 1-4 of level vocabulary as stated in the student's level of understanding of appropriate vocabulary.

The purpose of this study was to investigate whether young children with cleft palate differ from those of noncleft typically developing children in terms of expressive vocabulary size, phonological characteristics and lexical selectivity. A total of 12 children with cleft palate and 12 noncleft children who were matched by age and gender participated in the study. The groups were compared by size of expressive vocabulary reported on Korean version of MacArthur-Bates Communicative Development Inventories and the number of different words, consonant inventory, the percentage of words beginning with obstruents and vowels, nasal, and glottal sounds, and the percentage of words which do not include obstruents in a language sample. Also, correlation analysis were performed to examine the relationship between measures on size of expressive vocabulary and phonological characteristics. The results showed that expressive vocabulary size and consonant inventory for children with cleft palate produced significantly smaller than those for noncleft children. Children with cleft palate produced significantly more words beginning with vowel or which do not include obstruents, and fewer words beginning with obstruents than noncleft children. The two groups showed different results on significant correlations between measures on size of expressive vocabulary and phonological characteristics indicating that children with cleft palate show different lexical selectivity from their noncleft peers. The results suggest that children with cleft palate aged 18-30 months demonstrate a slower rate of lexical and phonological development compared with their noncleft peers and they develop lexical selectivity reflecting cleft palate speech. The results will have a clinical implication on speech-language intervention for young children with cleft palates.

The purpose of this study is to categorize a landscape adjective list for urban landscape analysis. For this purpose, four methods are used. The first method is to survey the foreign landscape adjective lists such as Feimer's EACL & LACL, VRM suggested vocabulary, and IEA and LI's aesthetic factors, which are commonly used in domestic research. The second method is to analyze vocabulary in Korean linguistic textbook the third is to investigate Korean adjective lists from 36 domestic research. The last is to survey adjectives used to express the urban landscapes. 24 landscapes from BunDdang, GwaCheon, YakSoo and ApGuJeong were presented to 40 subjects, whose responses were collected and categorized. The frequency analysis of the adjectives and landscape factors were processed by SJTOOL, which was programmed for Korean vocabulary analysis. The results of this study can be summarized as follows: Foreign adjective lists were mainly focused on the physical features of landscapes and they also had linguistic problems caused by the translations. Therefore, it is undesirable to use the foreign adjective list directly to analyze Korean urban landscapes. The vocabulary from the linguistic textbook has more variety, but it includes many adjectives irrelevant to the urban landscape. More types of adjectives were used in the researches(890 adjectives/295 types), compared with the result of response survey(1,406 adjectives/270 types). Because some adjectives were partly confusing, it is desirable to categorize the adjectives. The categorized adjectives could therefore be more useful and practical for urban landscape analysis.
