관계추출은 문장 내 두 개체 간의 의미적 관계를 추론하는 자연어분석 태스크이다. 딥러닝의 발전과 더불어 관계추출은 BERT 계열의 이해형 언어모델을 이용하였다. 그러나, ChatGPT의 혁신적인 등장과 함께, GPT계열의 생성형 언어모델에 대한 연구가 활발해졌다. 본 논문에서는 소규모의 생성형 언어모델(Kebyt5)을 이용하여 관계추출 성능개선을 위한 프롬프트 구성 및 생각의 사슬(CoT) 학습 방법을 제안한다. 실험결과 Kebyt5-large 모델에서 CoT 학습을 수행하였을 경우, Klue-RoBERTa-base 모델보다 3.05%의 성능개선이 있었다.

This study analyzed the introduction of addition and subtraction, including the composition and decomposition of numbers in the Korean, Singaporean, American, and Japanese elementary mathematics textbooks. The analytic foci of this study included visual models and their connections with the given problem contexts, the introduction of addition/subtraction or addition/subtraction sentences and their connections with the visual models, and additional activities for students to develop a relational understanding of the equal sign. The results of the analysis demonstrated diverse connections, mainly because the problem contexts, visual models, and the introduction of addition/subtraction or addition/subtraction sentences were implemented differently for each textbook. There were differences among the textbooks in what order of problem contexts were presented. Regarding the use of visual models, two textbooks tended to use one model consistently, whereas the other textbooks used various models depending on the problem contexts. There were subtle but significant differences in introducing addition/subtraction or addition/subtraction sentences. For a relational understanding of the equal sign, all textbooks included activities emphasizing that both sides of the equal sign are equal. Based on the results of this study, this paper closes with several implications related to the problem contexts to introduce addition/subtraction and addition/subtraction sentences as well as the use of visual models, which can serve as a basis for a new unit for the subsequent textbook.

This study is a descriptive study to investigate the relationship between verbal violence type, emotional response and coping in the operating room nurse. The subjects of the study were 400 nurses working in 20 general hospitals and 372 nurses in the operating room. As a result of the analysis, it was found that the perpetrators of the verbal violence experienced by the subject were physicians, direct supervisors, and more than half of the subjects were considering the transition. The most frequent cases of language violence were when the equipment was inoperable or not used during surgery, There were significant differences in verbal violence experience according to marriage, clinical career, and work style. Language violence emotional response showed significant difference with gender, position and coping, age, academic background, clinical career, and position. There was a significant correlation between experience of verbal violence and emotional response, emotional response and coping. Therefore, the results of this study will contribute to the development of coping strategies and prevention education programs.

기계번역에서 기능어의 번역은 각 언어가 고유의 문법적 특성과 표현방법을 가지고 있기 때문에 기능어가 가지는 의미와 문법적 기능을 자질로 표현하고 이를 통하여 해석과 생성을 한다. 한국어는 첨가어로 기능어가 매우 발달되어 있으며, 특히 조동사가 많은 문법적 기능을 담당하고 화자의 양태적 관계를 나타낸다. 따라서, 기계번역의 한국어 생성에서 조동사가 번역의 질에 상당한 영향을 미친다. 본 논문에서는 중간언어방식을 이용한 기계번역시스템의 한국어 생성에서 문법적 기능이나 양태적 관계를 나타낸 중간언어로부터 어떠한 조동사가 생성이 되어야 하고, 또한 조동사들간의 결합순서는 어떠한지를 살펴본다. 이를 위하여 Corpus를 분석하여 각 조동사 분류에 대한 대표 표층어를 선정하고 조동사간의 결합순서를 밝힌다. 조동사 생성을 위해 필요한 처리 과정과 언어적 지식베이스를 제안하고 시스템을 구현한다.

The purpose of this study is to determine whether the mean fundamental frequency (F0) changes depending on language, task, or language proficiency for Korean-English bilinguals. A total of forty-eight Korean-English speakers (28 balanced bilinguals and 20 Korean dominant bilinguals) participated in the study. Participants were asked to read aloud two types of tasks in English and Korean. For statistical analyses, the language ${\times}$ task two-way repeated ANOVAs were conducted within the balanced bilingual group first, and then group ${\times}$ language two-way mixed ANOVAs. The results showed that the females in both bilingual groups changed their mean F0 depending on the language they used and the tasks (p<.05), whereas no significant results were found in the males in either group under any conditions. The mean fundamental frequency in the Korean reading task was significantly higher than that in the English reading task for females in both balanced and Korean dominant bilingual groups. Thus, changes in mean F0 depending on language and context may reflect gender-specific characteristics, and females seem to be more sensitive to the socio-cultural standards that are imposed on them.

The purpose of this study is to analyze newspaper articles from corpus linguistic point of view. We used a large corpus of newspaper articles built from <21st century Sejong Project> and counted occurrences of certain expressions. A newspaper article is divided into the headline, the lead and the body. We tried to figure out how to measure the characteristics of indication and compression which are typical to headlines. Then, we focused on the differences between the headline and the lead. finally, we analyzed the sentence structure and measured the ratio of the frequency of common nouns in the body. This study verifies the existing stylistic theories of newspapers and shows new aspects of language use in newspaper articles. Texts like newspaper articles are the results of human language processing and they in turn affect the development of cognitive ability of language.

The purpose of this study is to analyze the learning objectives characteristics of educational programs of centers for the university affiliated science-gifted education using semantic network analysis, we examined the applicability of semantic network analysis in analyzing learning objectives by comparing the results of analysis with Bloom's revised taxonomy. For this purpose, 702 learning objectives presented in 169 science subjects were selected as subjects to be analyzed. After classifying and coding the learning objectives according to Bloom's revised taxonomy, we conducted a semantic network analysis to investigate the relationship between learning objectives. The results of the analysis are as follows. First, we looked at the number of learning objectives used for each subject, and about 3 elementary school levels and about 6 middle school levels were used. Second, the knowledge dimension such as 'factual and conceptual knowledge' and cognitive process dimension such as 'remember', 'understand', and 'create' was high regardless of the research method and school level. Third, the results of analysis based on the weighting through the semantic network analysis method, the elementary school level emphasize activities th be applied to the actual experimental process through learning about scientific facts, while the middle school level emphasize the understanding of scientific facts and concepts themselves. As a result, it can be seen that the semantic network analysis can analyze characteristics of various learning objectives rather than the conventional simple statistical analysis.

This study wanted to see if there was a difference in the development of counselors before and after sandplay education analysis and verbal education analysis. Ten people were selected for the sandplay education analysis and the level of counselor development before and after receiving the verbal education analysis, divided into three groups that received the verbal education analysis, and the three groups that received the language education analysis. A nonparametric test, Kruskal-Wallis test, was conducted to identify differences in the results of the pre-parametric test, and a nonparametric test, Wilcoxon signed tank test was conducted to identify differences in the pre-post test results. Studies have shown that there is a statistically significant difference in the overall development of counselors and in case of case, in the whole of sandplay education analysis groups, while those that received verbal education analysis and those that did not receive education analysis do not have a statistically significant difference in the level of counselors development. This study is meaningful as it proves that sand play education analysis is effective in the development of counselors.

결속성은 텍스트의 의미 관계 분석에서 주요하게 고려되는 요인 중 하나이다. 결속성이 높을 수록 텍스트 내 언어적 의미 관계가 긴밀한 것으로 볼 수 있기 때문이다. 사람에 의한 텍스트 결속성 분석은 주관이 개입되는 문제를 배제할 수 없는데, 영어에는 TAACO라고 불리는 결속성 자동 측정 도구가 있어 다양한 지표들로 텍스트의 결속성을 측정하고 있다. 그러나 한국어에는 이와 같은 텍스트 결속성 자동 측정 도구가 거의 없으며, 관련 연구도 상당히 부족한 실정이다. 따라서 본 논문에서는 한국어 텍스트의 의미 관계 분석을 위한 결속성 지표를 정의하고, 한국어의 특성에 맞는 결속성 측정 도구인 KorCAT을 제안한다.
