  • A smart tourism chatbot is needed as a user interface to efficiently provide smart tourism services such as recommended travel products, tourist information, my travel itinerary, and tour guide service to tourists. We have been developed a smart tourism app and a smart tourism information system that provide smart tourism services to tourists. We also developed a smart tourism chatbot service consisting of khaiii morpheme analyzer, rule-based intention classification, and tourism information knowledge base using Neo4j graph database. In this paper, we develop the Korean and English smart tourism Name Entity (NE) datasets required for the development of the NER model using the pre-trained language models (PLMs) for the smart tourism chatbot system. We create the tourism information NER datasets by collecting source data through smart tourism app, visitJeju web of Jeju Tourism Organization (JTO), and web search, and preprocessing it using Korean and English tourism information Name Entity dictionaries. We perform training on the KoBERT-CRF NER model using the developed Korean and English tourism information NER datasets. The weight-averaged precision, recall, and f1 scores are 0.94, 0.92 and 0.94 on Korean and English tourism information NER datasets.

  • This study aims to see some prosodic features of English spoken by Japanese learners of English. It focuses on speech rates, pauses, and intonation when the learners read an English passage. Three Japanese learners of English, who are all male university students, were asked to read the speech material, an English passage of 110 word length, at their normal reading speed. Then a native speaker of English, a male American English teacher. was asked to read the same passage. The Japanese speakers were also asked to read a Japanese passage of 286 letters (Japanese Kana) to compare the reading of English with that of japanese. Their speech was analyzed on a computerized system (KAY Computerized Speech Lab). Wave forms, spectrograms, and F0 contours were shown on the screen to measure the duration of pauses, phrases and sentences and to observe intonation contours. One finding of the experiment was that the movement of the low speakers' speech rates showed a similar tendency in their reading of the English passage. Reading of the Japanese passage by the three learners also had a similar tendency in the movement of speech rates. Another finding was that the frequency of pauses in the learners speech was greater than that in the speech of the native speaker, but that the ration of the total pause length to the whole utterance length was about tile same in both the learners' and the native speaker's speech. A similar tendency was observed about the learners' reading of the Japanese passage except that they used shorter pauses in the mid-sentence position. As to intonation contours, we found that the learners used a narrower pitch range than the native speaker in their reading of the English passage while they used a wider pitch range as they read the Japanese passage. It was found that the learners tended to use falling intonation before pauses whereas the native speaker used different intonation patterns. These findings are applicable to the teaching of English pronunciation at the passage level in the sense that they can show the learners. Japanese here, what their problems are and how they could be solved.

  • Literature had been at center-stage in the traditional grammar-translation-focused English classrooms up to the mid-twentieth century. As the Audiolingual Method and the Communicative Language Teaching have gained popularity in the English classrooms, however, literature has receded into the background of English education. The main reasons for using literary texts in the English classrooms for communication-focused English instruction need to be examined. First of all, students can come in touch with the subtle and varied uses of language through literature-based teaching. They also feel close to certain characters in the literary work and share the emotional reponses with them. They get personally involved in the plot of the story. Universal human experience and cultural enrichment are two other merits which can be conferred on students by literary texts. Such linguistic and literary experiences can be significantly integrated into the literature-based instruction. More significantly, the four language skills (reading, writing, listening and speaking) can be combined with one another and integrated into a literature-focused curriculum for English education. The value of literary texts in the English classrooms can be clearly demonstrated by effective ways of using such texts as Charlotte's Web for integrated instruction. The full array of benefits that literature can bring to English instruction, however, has yet to be fully realized. These potentials need to be materialized into classroom practice.

  • Using literary materials as resources for English learning rather than an object of literary study can be a genuine tool for the students to learn English in the form of oral and written communication. This case study treated the applications of a whole text to the overall course divided into pre-reading activities, while-reading activities, and post-reading activities and the applications of some partial passages extracted from various texts to teaching objectives with many levels of difficulty. This study found that literary texts could be good materials to teach the target language in EFL setting. The English-speaking students with little linguistic competence as a foreign language may be limited in learning English at first, but soon they can accelerate their linguistic competence by reinforcing the literary competence through the literary texts. To achieve effectively a desired goal through the use of literary texts as resources for language development several concrete techniques should be introduced: teacher-guided question strategies laying a central emphasis on the text itself, a problem-solving ability through student-centered activities, process-based and open-ended activities should be presented in a variety of ways using many appropriate activities according to teaching procedure with a careful selection of the texts.

  • This study examined how the use of learning apps in Zoom-based classes affects learners' English achievement and assessed the efficiency of app use in Zoom-based English classes. The study utilized the English Central (EC) app to induce learners to actively participate in zoom-based classes. To assess the app's efficiency, two rounds of achievement tests and an open-ended questionnaire were administered. The two tests showed that Zoom-based EC app utilization classes positively affected learners' English achievement and the questionnaire revealed that the learners were highly satisfied with using the EC app in Zoom-based classes. The participants praised this approach for "complementing insufficient class content" and facilitating "immediate feedback" (on the EC app), "English practice," and "real-time communication and sharing of opinions" (on Zoom-based classes), describing it as "not boring" and "4 skill training in English." Instructors should strive to efficiently use such new teaching tools in the evolving environment of the untact era.

  • The purpose of this study is to guide efficient ways to teach cultural aspects in Korean elementary English education through analyzing many studies on elementary English culture education. In global era, English education must be performed based on understanding of other various cultures for authentic communication. However, Korean elementary students have difficulty to approach or to be exposed to the culture of English speaking countries. Elementary English culture education is neither well organized nor performed for some reasons. The reasons are as follows. Frist, English teachers are not confident with the culture and they consider themselves not having enough experiences and knowledge to teach. They were not taught cultural aspects and the cultural aspects were not emphasized. Second, there are not appropriate culture related teaching materials in the textbooks and teachers' guide books. Therefore, necessary cultural aspects should be selected by English education experts and provided in the textbooks and teachers' guide books. Those two books should be systematically connected. Elementary English teachers should have more opportunities to understand and experience other various cultures. Language is a part of culture and culture is a part of language. Acquiring the second language is acquiring its culture. The culture education for authentic communication is accomplished from managing cultural aspects in textbooks and cultivating English teachers with experience and understanding of target culture.

  • In this study, the number of non-English speaking visitors is increasing day by day, and accordingly, there was a limitation in language communication and communication during radiographic examination. To this end, after distributing the handbook produced for inspection, the improvement effect of before and after explanation was examined. The score scale was not statistically significant as to whether it was the test site or not, and the degree of discomfort of the test, the degree of understanding of the breathing guidelines, and the satisfaction of the test description were improved and the score scale was improved before and after the description of the guide. Non-English-speaking foreign visitors were more satisfied with explanations in their own text than in English or Korean, and the method was also able to conduct effective inspections by informing the foreign guests when to control their breathing by using the lighting signals in the laboratory. In the future, the quality of medical services and imaging medical examinations can be improved only when communication methods are implemented from various perspectives, such as developing various language interpretation programs, developing guides for various test sites, and developing tools and improving foreign language skills of radiologists and medical staff. There will be. In the future, it may be used as a basic resource to prepare a manual that can be used to examine non-English speaking foreigners who do not understand English or Korean in other radiology labs.

  • YouTube, the online video streaming platform, has become popular and influential around the globe. Due to the development of science and technology, people without expertise in filming can now easily produce their videos with unique content. Many people are more eager to become a popular YouTube creator because they can earn money by placing commercials or Products in Placement (PPL) in their video clips. However, it is yet unknown what genres of YouTube videos are popular. YouTube creators have their channels where they upload videos of a certain type of genre. This study investigates video genres of the top 250 YouTube channels in English-speaking countries (United States, Canada, United Kingdom, and Australia) using Social Blade, which is a research website. The ranking is set based on the number of times people watched a video ("Video Views"). We handsomely analyze popular genres of the channels and also the YouTube ecosystem, and it will be meaningful for today's new media era.

  • This case study explored the potential for implementing content-based English as a Foreign Language (EFL) instruction in a Korean middle school facilitated by computer-mediated communication (CMC). The instructor scaffolded the student participant's language learning online, helping her to produce English output on her own. While experimental social studies lessons on the topic of stereotyping were taught, data were collected on the student's online exchanges with her counterpart in Iran about their respective cultures. Findings show that the student from Korea was able to better understand her own culture as a result of the online experience. This interaction and the in-class lessons have demonstrated that content-based EFL instruction is a viable alternative to the school's existing curriculum.
