본 연구는 남북한 영어교과서에 나타난 어휘를 비교하여 영어어휘의 양적 질적인 차이를 알아보고 궁극적으로 남북한 통일 영어교과서에 담을 영어어휘 목록을 만드는데 필요한 기초적인 작업을 진행하는데 있다. 이를 위해 2000년대에 출간된 남북한 영어교과서로 코퍼스를 구축하여 어휘목록을 추출하고 이들 남북한 영어교과서 코퍼스를 비교하였다. 어휘목록의 추출은 남한 영어교과서의 경우는 7차교육과정 이후 출간된 교과서에서 추출하고 북한 영어교과서의 경우는 김정일정권시대인 2000년대 이후 영어교과서로 코퍼스를 구축하고 그 코퍼스에서 어휘목록을 만들어서 비교하였다. 이를 위해서 AntConc 3.5.7을 사용하여 어휘목록을 추출하고 콘코던스를 통해서 어휘목록에 나온 어휘의 사용맥락을 살펴보면서 점검하였다. 이를 통해서 남북한 영어 어휘의 양적 질적 비교를 통해서 그 차이점들을 도출하였다. 양적으로 남북한이 영어교과서를 통해서 학습해야 할 어휘는 양적으로 비슷하게 3000 단어 내외였으나 북한 영어교과서의 경우 전문학술 어휘가 좀 더 많이 나타났다. 자본주의 시장경제를 따르는 남한과 사회주의 계획경제를 따르는 북한 영어교과서에는 이와 관련된 어휘의 사용과 의미적 차이가 발견되었다. 아울러, 종교와 문법 용어의 사용에 있어서 차이가 나타났다.

This study lists the vocabulary of the inscriptions on SeoGwol-YeongGeon-DoGam-UiGwe(西闕營建都監儀軌 1831). This study also deciphers and explains the meanings of them. In advance, this study compares them with the vocabulary of the national language in the middle ages and in modem times. There are two important missions in deciphering a transcription marking of the architectural vocabulary of UiGwe(儀軌). One is to gain an understanding of the reading method of transcription marking and the other is an explanation of what that means. As a result, we can correctly understand the UiGwe(儀軌) written in transcription marks. If we could decipher the transcription markings of the documents as it is, we cannot only recover plenty of vocabulary related with characteristic architecture in the age of the later Joseon Dynasty, but also correct wrongly used vocabulary in the present. As a result, we can standardize and adjust the vocabulary use of Korean traditional architecture. In advance, we can correct errors of spelling and mistaken explanations in the Korean Encyclopedia.

In this paper, we investigated performance of a vocabulary-independent speech recognizer with speaker adaptation. The vocabulary-independent speech recognizer does not require task-oriented speech databases to estimate HMM parameters, but adapts the parameters recursively by using input speech and recognition results. The recognizer has the advantage that it relieves efforts to record the speech databases and can be easily adapted to a new task and a new speaker with different recognition vocabulary without losing recognition accuracies. Experimental results showed that the vocabulary-independent speech recognizer with supervised offline speaker adaptation reduced 40% of recognition errors when 80 words from the same vocabulary as test data were used as adaptation data. The recognizer with unsupervised online speaker adaptation reduced abut 43% of recognition errors. This performance is comparable to that of a speaker-independent speech recognizer trained by a task-oriented speech database.

The role of social networking mobile applications such as WhatsApp in enhancing second language vocabulary learning among English language learners continues to be a subject of interest for many scholars. The current study aimed at examining medical English vocabulary learning among undergraduate students using WhatsApp compared to learning vocabulary via the Blackboard platform during the Covid-19 pandemic. To this end, 108 medical students (51 males, 57 females) enrolled in a first semester English for a specific English course participated in the study. A quasi-experimental design was adopted for two groups. Fifty-three students participated in the WhatsApp group and 55 students formed the Blackboard group. A pretest-posttest design was employed to collect data. Results of t-test scores did not show a significant difference between the WhatsApp and Blackboard groups on a vocabulary test. Results of a survey that measured students' opinion of the use of WhatsApp as a platform for learning new vocabulary showed positive perceptions since participants thought that WhatsApp enhanced their learning experience.

A sample of 322 18-month-old infants and their mothers were assessed longitudinally at 24 and 30 months. Maternal utterances and styles of linguistic interaction were measured during a 10 minute free play session. Mothers completed a vocabulary checklist for infants. Longitudinal data were analyzed by multilevel modeling. Results indicated that vocabulary increased with age of infants and the growth rate was highly predictable by the size of vocabulary at 18 months. The growth rate was strongly influenced by maternal questioning and feedback. The effect of the maternal linguistic input was constant with age. Gender differences in size of vocabulary did not vary systematically with age.

This study's purpose is to examine the effects of mobile apps on learners' vocabulary acquisition and to analyze students' perceptions and opinions about the vocabulary app. To this end, this study set up a control group, which was given explicit instructions in the classroom by the instructor and an experimental group, which used a vocabulary app. The vocabulary acquisition test results suggested that the difference between the the two groups was insignificant. However, user satisfaction with regard to the mobile app was high, and the reasons given were the following: convenience, efficiency of memorizing, having fun while learning, and the app's interface. Based on these results, this study suggests that teachers should use mobile apps much more actively in classroom instruction, and encourge students to let apps play a more active role in their language studies.

In this paper, we propose a vocabulary coverage improvement method for embedded continuous speech recognition (CSR) using knowledgebase. A vocabulary in CSR is normally derived from a word frequency list. Therefore, the vocabulary coverage is dependent on a corpus. In the previous research, we presented an improved way of vocabulary generation using part-of-speech (POS) tagged corpus. We analyzed all words paired with 101 among 152 POS tags and decided on a set of words which have to be included in vocabularies of any size. However, for the other 51 POS tags (e.g. nouns, verbs), the vocabulary inclusion of words paired with such POS tags are still based on word frequency counted on a corpus. In this paper, we propose a corpus independent word inclusion method for noun-, verb-, and named entity(NE)-related POS tags using knowledgebase. For noun-related POS tags, we generate synonym groups and analyze their relative importance using Google search. Then, we categorize verbs by lemma and analyze relative importance of each lemma from a pre-analyzed statistic for verbs. We determine the inclusion order of NEs through Google search. The proposed method shows better coverage for the test short message service (SMS) text corpus.

정보검색의 성공여부는 적절한 검색어의 선정에 달려있다고 해도 과언이 아니다. 특히 CD-ROM이나 온라인목록시스템에서 주제검색시 분류표, 주제명과 같은 통제어와 자연어 등 비통제어의 비교 우위 문제는 아직도 논란이 되고 있다. 본고는 두 시스템의 검색효율성을 비교하기 위하여 특히 다언어 환경하에서의 검색어 사용에 중점을 두고 다양한 형태의 검색어휘를 조사 분석하였다.

Objectives: This study was aimed to identify the expressions used by consumers to talk and by mediator to provide information about hypertension in the internet and suggest more understandable vocabulary for consumers. Methods: A researcher collected archival postings associated 78 hypertension-related vocabularies from internet websites for extracting consumer and mediator vocabulary respectively. Then, the consumer and mediator vocabularies with the same meaning as 78 vocabularies were extracted from postings collected by two non-professional extractors and a researcher, respectively. Both consumer and mediator vocabularies manually mapped to the 78 hypertension-related representing vocabularies. Finally, the survey was conducted from 110 inpatients and 115 nurses from December 27 to 31, 2013 for the selection of recommended vocabulary related to hypertension. Data were analyzed using the SPSS program and included descriptive statistics. Based on the survey results, the recommended vocabularies were selected for laypersons. Results: 67 consumer and 73 mediator vocabularies were linked with the 78 vocabularies. Two vocabularies unmapped to both consumer and mediator vocabularies were 'wheeze' and 'angioplasty'. 49 recommended vocabularies related to hypertension were selected for helping laypersons understand hypertension information. Conclusions: The consumer-oriented vocabularies may be helpful to overcome the vocabulary problem between non-professionals and professionals.

본 연구는 초급 한국어 학습자들의 어휘 학습에 대한 인식과 애플리케이션 클래스카드를 활용한 어휘 학습을 일반적으로 쓰면서 외우는 어휘 학습 방법과 비교하여 효과를 살펴보는 것에 목적이 있다. 이를 위해 D대학교 한국어교육원 1, 2급 초급 한국어 학습자 24명을 대상으로 통제 집단 12명, 실험 집단 12명으로 나눈 후 어휘 평가지를 통하여 두 집단의 학습 전, 후 성취도를 살펴보았다. 실험 결과에 따르면 애플리케이션 클래스카드를 활용하여 어휘 학습을 한 학습자들의 어휘 점수가 크게 향상되었고 통계적으로 유의미한 결과를 보여 클래스카드를 활용한 어휘 학습의 효과성을 입증하였다. 또한 설문 조사를 통해 학습자들이 애플리케이션 클래스카드를 활용한 어휘 학습에 대한 거부감을 느끼지 않으며 쉽게 어휘를 공부할 수 있는 어휘 학습 방안 중 하나로 생각하고 있어 애플리케이션을 활용한 어휘 학습이 학습자들의 학습 성취도와 정의적인 측면에도 긍정적인 영향을 미치는 것을 알 수 있었다. 본 연구는 애플리케이션을 활용한 어휘 학습의 효과를 입증함으로써 학습자들의 흥미도와 어휘력을 높일 수 있는 어휘 학습 방안을 제안했다는 것에 의의가 있다.
