선박무선통신장비는 선박이 항해하는데 필요한 안전정보, 선박교통 모니터링 및 관제, 입·출항 정보를 교환하기 위한 필수 장비이므로 선박항해사는 무선통신 내용을 항상 주의 깊게 청취해야 함. 본 연구에서는 선박의 실제 음성 교신데이터 500시간 데이터를 수집 및 학습하고, Wav2Vec 및 Whisper 모델을 활용하여 한글 및 영어(해사영어) 음성인식 모델을 개발하고 실용화를 수행하였다. 음성인식 모델의 성능은 CER(Character Error Rate) 기준 94.5%로 향후 선박 운항 관련 댜양한 분야에 적용이 가능할 것으로 사료된다.

The purpose of this study Is to analyze and describe the characteristics of the information needs and information seeking behavior of ST information users of the KISTI. Questionnaires were distributed to the ST information users in the academic, industrial, and scientific sectors via mail. The role of the KISTI as the specialized information source and intermediary for other institutional information sources as well as individual users and the need for improving the strategies for customer-based services and collection development were evaluated. Major findings include the need for a more comprehensive effort to collect, preserve, and communicate the ST information resources. the need for much broader collection of journals and conference proceedings to provide the documents "on demand" for users, and the need to improve DDS in general.

In this paper, we present an Example-based Dialogue System for English conversation tutoring. It aims to provide intelligent one-to-one English conversation tutoring instead of old fashioned language education with static multimedia materials. This system can understand poor expressions of students and it enables green hands to engage in a dialogue in spite of their poor linguistic ability, which gives students interesting motivation to learn a foreign language. And this system also has educational functionalities to improve the linguistic ability. To achieve these goals, we have developed a statistical natural language understanding module for understanding poor expressions and an example-based dialogue manager with high domain scalability and several effective tutoring methods.

This paper aims to explore a comparative instructional effects among meaning-based communicative language teaching, input-enhanced FnF instruction and output-enhanced FnF instruction in order to optimize the teaching methods of target grammar and vocabulary. The experiment selected three homogeneous groups of 30 students in each group for the comparison: One comparative group with communicative language teaching, one input-enhanced FnF group and another output-enhanced FnF group. The result indicates that the input-enhanced group outperformed the comparative group in the grammar test with statistical significance and the output-enhanced group overweighted the comparative group in the vocabulary test. However, no significant statistical difference was found between the input-enhanced group and the output-enhanced group. The conclusion from the result could bear the following pedagogical implication: The general English education must use the eclectic method of adopting communicative language teaching with FnF of input-enhanced target grammar and output-enhanced target vocabulary to supplement the students with the basic vocabulary and grammar.

The present study was conducted to investigate science and engineering graduate students' proficiency in technical English writing and their perceptions of research ethics. Given that graduate students in science and engineering colleges usually write journal articles as well as dissertations in English, this study examined their experience of and preparation for technical English writing, writing practices, and research ethics including plagiarism. The results of the study show that it is very necessary to intensify education on research ethics and to provide educational training in proper citation practices. These findings can be used as a basis for the development of future academic curricula and other support resources to improve science and engineering graduate students' technical English writing.

In order to attain the best-educated people in a rapidly changing, modern society with English is an official language, this study applies the problem-based learning (PBL) method to the English Science Class. PBL problems were developed for PBL classes, and their effectiveness has been proven. The focus of this study was five PBL questions posed during the first semester, targeting seven learners in the fourth grade of Elementary School A. The questions were divided into levels aimed at each grade, with the emphasis on specialized English education. Learners wrote journals, peer evaluations, and self-evaluations after finishing their PBL classes. Also, a survey about PBL was conducted after the first semester. The results of the study showed that learners experienced an 86% improvement in presentation skills, an 86% improved interest in learning, 86% better understanding, and 100% improvement in both problem-solving skills and cooperation. On the other hand, learners had difficulty in understanding PBL problems, and with research using the internet. PBL was somewhat unfamiliar to the students, but the survey found that learners are already aware of its effectiveness, and that they are interested in PBL.

상호참조해결은 자연언어 문서 내에서 같은 개체를 나타내는 언급들을 연결하는 문제다. 대명사, 지시 관형사, 축약어, 동음이의어와 같은 언급들의 상호참조를 해결함으로써, 다양한 자연언어 처리 문제의 성능 향상에 기여할 수 있다. 본 논문에서는 현재 영어권 상호참조해결에서 좋은 성능을 내고 있는 BERT 기반 상호참조해결 모델에 한국어 데이터 셋를 적용시키고 표층형을 이용한 규칙을 추가했다. 본 논문의 모델과 기존의 모델들을 실험하여 성능을 비교하였다. 기존의 연구들과는 다르게 적은 특질로 정밀도 73.59%, 재현율 71.1%, CoNLL F1-score 72.31%의 성능을 보였다. 모델들의 결과를 분석하여 BERT 기반의 모델이 다양한 특질을 사용한 기존 딥러닝 모델에 비해 문맥적 요소를 잘 파악하는 것을 확인했다.

본 논문에서는 BERT가 합성된 새로운 Transformer 구조를 제안한 선행연구를 보완하기 위해 cardinality residual connection을 적용한 새로운 구조의 모델을 제안한다. Transformer의 인코더와 디코더의 셀프어텐션에 BERT를 각각 합성한 모델의 잔차연결을 수정하여 학습 속도와 번역 성능을 개선하고자 한다. 그리고 가중치를 다르게 부여하는 실험으로 어텐션을 선택하는 효과적인 방법을 제시하고 원문의 언어에 맞는 BERT를 사용하는 이유를 설명한다. IWSLT14 독일어-영어 말뭉치와 AI hub에서 제공하는 영어-한국어 말뭉치를 이용한 실험에서는 제안하는 방법의 모델이 기존 모델에 비해 더 나은 학습 속도와 번역 성능을 보였다.

This paper presents a new approach to describing the meanings of English relative clauses with the theoretical framework of Conceptual Structure Theory (henceforth CST)which builds on the pionerring work of Sowa.And this paper aims at proposing some extensions to his work. CST describes the conceptual structrures of sentences with conceptual graphs(henceforth CG). which have begun to be used as an intermediate language in natural language processing and machine translation of computer.CGs are composed of concept types and conceptual relation types. They are a system of logic for semantic representation of sentences. This paper focuses on showing the differences of the CGs according to the functions of English relative clauses. English relative clauses are divided into restrictive and nonrestrictive uses.And this paper describes a restrictive clause with a CG including a expression.which derives from the viewpoint of Montague-semantics and Nom-S Analysis.This paper deals mainly with the relative clauses of double restroction as an example of restrictive relative clauses.The description of a nonrestrictive relative clause does not need any-expression, for it doesn's involve the meaning of set.And this paper links the CG of an appositive relative clause,which is a kind of nonrestrictive clauses,to the concept of the antecedent in the main clause.The description of a nonrestrictive relative clause with adverbial meaning is strated with two CGs for the main clause and the relative clause.They are linked with an appropriate intersentential conceptual relation type according to the contextual realtions between them.This paper also presents a CG of a sentential relative clause,which gives a comment on the main clause.
