초대규모 언어모델의 뛰어난 생성 기술이 실질적인 부분에서 많은 도움을 주고 있음에도 불구하고 사람들의 마음을 움직일 수 있는 매력적인 광고 카피를 생성하기에는 아쉬운 점이 많다. 이 연구는 효과적인 광고 카피 자동생성을 위한 데이터 구축 방법론 연구로, 데이터에 일관적으로 학습시킬 수 있는 감성적 카피의 문체적 특징을 프레임워크로 정의하고 이를 모델에 적용한 결과를 보여 데이터 설계 방법론의 유효성을 검증하고자 하였다. 실험 결과 문체 적합성 측면에서 성공적인 결과를 확인한 것에 비해, 한국어 보조사와 같이 미세한 어감 차이를 발생시키는 요소나 의미적 중의성 해석 등의 고차원적인 한국어 구사능력을 필요로 하는 부분에서 생성모델의 개선 여지를 발견할 수 있었다. 본 연구에서 보인 감성형 카피 생성을 위한 프레임워크는 마케팅 실무에서도 유용하게 사용될 수 있을 뿐만 아니라, 고객 세그멘테이션 분석이 이루어진다면 타깃 고객의 취향을 고려한 효과적이고 맞춤화된 광고 카피를 생성에 기여할 수 있을 것으로 기대된다.

최근 ChatGPT와 같은 사전학습 생성모델은 자연어 이해 (natural language understanding)에서 좋은 성능을 보이고 있다. 또한 코드 작업을 도와주고 대학수학능력시험, 중고등학교 수준의 문제를 풀거나 도와주는 다양한 분야에서 활용되고 있다. 본 논문은 사전학습 생성모델을 이용하여 영어 교육을 위해 말뭉치를 확장하는 프레임 워크를 제시한다. 이를 위해 ChatGPT를 사용해 말뭉치를 확장 한 후 의미 유사도, 상황 유사도, 문장 교육 난이도를 사용해 생성된 문장의 교육적 효과를 검증한다.

CEFR(Common European Framework of Reference for Language)는 유럽 전역의 교육기관에서 언어구사 능력을 평가하는 평가 기준이다. 본 논문은 학습자가 문장 작문한 것을 CEFR 에 기반하여 평가하는 모델을 기술하는 것을 목표로 한다. CEFR 기반 문장 작문 평가는 크게 전처리 단계, 작문 단계, 평가 단계로 구성된다. CEFR 기반 문장 작문 평가 모델의 평가는 CEFR 수준별로 분류한 문장들이 전문가의 수동 분류와 일치하는 지의 정확도와 학습자가 작문한 결과의 자동 평가로 측정되었다. 실험은 독일어를 대상으로 하였으며 독일어 전공 41 명의 대학생에게 CEFR 6 등급별로 5 문장씩 총 30 문장의 2 세트를 만들어 실험을 실시하였다. 그 결과 CEFR 등급별 자동 분류는 전문가의 수동 분류와 61.67%로 일치하는 정확도를 보였다.

With the advance of digital technology, new methods which acquire color information and combine it with various contents are emerging. Color has some effect on emotion while it gives some information as component of an image. In addition, change in emotion and sensation from color stimulus makes some change in cognition. This research investigate the effect of color overlay on cognition depending on emotional state. With this goal, subjects consisting of 10 men and 10 women solved some problems with color overlay of red, orange, and green after watching short video clips which intend to induce target emotion. Experimental results show that red color overlay under positive emotion significantly reduces the average score of solving problems, while green overlay under negative emotion significantly increases it. It is also analyzed that there is not statistically significant difference in cognitive function with color overlay while it is significantly better under positive emotion than negative emotion without color overlay.

This study was conducted to describe the relationship of Communication Skill, Communication Self-Efficacy and Communication Related Educational Needs of nursing students. The participants were 206 nursing students in K City who were surveyed using self report questionnaires and the data was analyzed using SPSS 20.0. 83.5% of nursing students answered communication related education was necessary and they preferred practice centered communication education through role-play. And there was a significant positive correlation between Communication Skill and Communication Self-Efficacy. The results of this study provided a foundation to develop efficient communication program to improve interpersonal relationship of nursing students.

The current study aimed to examine university students' perceptions of the positive effects of L2 oral presentations in terms of communication skills and future employment. The participants were 13 undergraduate students enrolled in L2 oral presentation classes at the beginner or intermediate level. This study followed a qualitative research approach using in-depth and semi-structured interviews as the primary method. The findings revealed that students largely exhibited the benefits of oral presentations in three ways: by enhancing L2 proficiency, building confidence in public speaking, and gaining competitive advantages in their future careers. As a challenge for L2 learners, oral presentations were considered fundamental to develop effective communication skills in academic and professional contexts.

This study aimed at designing an effective earth science instruction which would help to improve students' scientific creativity using the questioning strategies. The developed questioning strategies were applied to 153 students of $10^{th}{\sim}11^{th}$ grades from March, 2004 to February, 2006. The Reaction Evaluation of Educational Program was used for students' reponses on these questioning strategies. And the Creativity Test developed by the Korea Institute for Aptitude Test was used for the changes of students' scientific creativity. The students responded that these questioning strategies improved students' scientific creativity, and those did not promoted interaction between the teacher and the students. After implementing these questioning strategies, students' analogical ability of language was evaluated the largest score among the 6 categories of scientific creativity. The survey about students' scientific creativity showed that there are meaningful differences between before and after implementing these questioning strategies : analogical ability of figure, analogical ability of language, reading comprehension ability.

This study aims to investigate the effects of literary texts as a teaching tool to enhance college students' English communicative competence both in linguistic aspects and affective ones. The control group used only the course book as study material, whereas the target group read four short stories along with it and engaged in a series of follow-up tasks. To measure their English competence, the researcher had both groups take a pre-test and a post-test, compared the results, and analyzed the data using SPSS. The study indicates that though the target students' post-test scores increased, the result failed in reaching a significant level. Nevertheless, reading and discussing literature facilitated the target students' affective aspects of communication. This article points out some other limitations of utilizing literary texts in language teaching and suggests the need for further research to deal with the issues.

The purpose of this study was to provide basic data for the selection of educational contents when developing a course for cultivating global business communication competence. Reviewing previous studies on sub-elements of global competence, the researcher selected the sub-elements of global business communication competence. A survey was conducted on 148 employees of 20 companies regarding the importance of the sub-elements of global business communication competence. As a result, it was concluded that the sub-elements of relatively high importance-English email writing, reading and understanding of English materials and documents, telephone English, business English conversation, understanding of other cultures, communication skills, business knowledge-should be included in the educational contents of a course for cultivating global business communication competence.

Since the problem-based learning (PBL) shows the effectiveness of self-directed learning ability and internalization of learning motivation in the process of solving real problems, studies on PBL and application cases are actively pursued in the university education. This study analyzed the effects of PBL on the academic achievement and computational thinking in a non-SW major students' programming course. The programing course was divided into the PBL class and non-PBL class, and at the end of the classes, the scores of the exams and the results of questionnaires about the educational effectiveness and computational thinking were analyzed. As a result, the students in the PBL class, compared to those in the non-PBL class, showed significantly higher scores in the areas of the algorithm implementing skill, self-directed learning, problem solving ability, and continuous learning motivation.
