This paper deals with the telicity variability on the point of Pustejovsky's (2000) event structures. Accomplishments and achievements have been known to show the telicity. According to Hay, Kennedy, and Levin (1999), however, open-range predicate in degree achievements, which do not show telicity, can show telicity in certain context. In order to explain this kind of telicity variability systematically, I will discuss Pustejovsky's (1995) Generative Lexicon Theory and the co-composition generative mechanism in section 2. In section 3, I will discuss Hay, Kennedy, and Levin's (1999) telicity variability and Lee Chungmin's (2000) modified extended lexical structure. In section 4, I will introduce Pustejovsky's (2000) event structures and modify them a little. And I will argue that the modified event structures can explain the telicity variability with the co-composition generative mechanism efficiently.

In this paper I am arguing in favour of more vigilance on the part of the Korean linguistics' melieu and, if deemed necessary, a more solid epistemological foundation of the Korean Linguistics. The purpose of this work consist in providing some epistemological inquiry on the major orientations and tendencies which are manifested in the reception of western linguistic theories. I might call this point of view as a critical approach to the philosophy and history of Korean linguistics. In the first section, I gave a short description of the model of the linguistic historiography which can be applied to the history of the Korean linguistics. In the second section, I am concerned with the comparative epistemology of the development of linguistic ideas produced in the West and East. In the final section, I made some critical reflections on the limits of Korean linguistics.

Programmed grammars, one of the most important and well investigated classes of grammars with context-free rules and a mechanism controlling the application of the rules, can be described by graphs. We investigate whether or not the restriction to special classes of graphs restricts the generative power of programmed grammars with erasing rules and without appearance checking, too. We obtain that Eulerian, Hamiltonian, planar and bipartite graphs and regular graphs of degree at least three are pr-universal in that sense that any language which can be generated by programmed grammars (with erasing rules and without appearance checking) can be obtained by programmed grammars where the underlying graph belongs to the given special class of graphs, whereas complete graphs, regular graphs of degree 2 and backbone graphs lead to proper subfamilies of the family of programmed languages.

In the history of linguistics in the world the scholars in India could be regarded as the representative linguists, who had provided the cornerstone of the academic development at linguistics. Without looking into the contents of Indian linguistic theories devised and developed in the past it would be almost impossible to account for the origin of descriptive linguistics and historical linguistics. These linguistics trends became full-fledged in 19 and 20 century and are still accepted by a lot of researchers in order to analyze newly revealed languages and train students only coming up the toddling level of linguistic studies. In this paper I will show how far the influence of Indian linguistics has colored the flow of linguistic growth historically. Especially through the analysis of Panini grammar I will prove the intimate relationship between the Indian linguistic theory and the generative grammar - it is the most active theory at present. The methods that Panini applied to constitute the rules like sutra include lots of information, that also could be discovered at the rules postulated in the generative grammar. One of the common features found at both linguistic theories is the simplicity of rule representation. At the generative grammar a rule has to be established without any redundancy. When certain number of sounds like p, b, m show the same phonological. change relevant to lips (labial in linguistic term) different rules need not to be given for each sound separately. It is better to find a way of putting the sounds together in a rule with grouping the 3 sounds with the shared phonetic feature 'labial'. In Panini grammar the form of a rule was decided based on the simplicity, too. For example, sutra 6.1.77 shows the phonological connection between the vowels i, u r 1 and the semi-vowels y, v, r, 1. However, it does not require to postulate 4 individual rules respectively. Instead a rule in which the vowels and the semi-vowels are involved is suggested, and linguistically the rule make it clear that the more simpler the rules will be the better they can reflect the efficiency of human language acquisition. Although the systems introduced at Panini grammar have some sense of distance from the language education itself we cannot deny the fact that the grammar formulates the a turning point of linguistic development. It is essential for us to think over the grammar from the view point of the modem linguistic theories to understand their root and trunk more thoroughly. It will also help us to predict in which way linguistic tendency will proceed to in future.

As the late partner to science fiction, various experimental languages such as animal language, telepathic language, newly invented language, alien language often appear as "unexpected and frightened situations" in SF. Like generative semanticists, some SF writers daringly delve into the sacred mystery of semantics in language whereas others avoid the dream of a universal language by holding themselves to manageable data. Samuel Delany's description of the ideal telepathic universal language in Babel 17 shows us humans' dream to be like God by showing to us the new process of communication in the factual interplanetary environment. Similar to the mystery of alien language in SF, the baby's babbling reveals how language is both simple and complicated. Children's language shows us the changing process of a soul revealed by language use and it is no wonder that many languages of AIs in SF often borrow their source from children's language acquisition processes. In short, science fiction as the repository of tropes illuminates other literary language studies and other literary genres. Especially in terms of the futuristic study of linguistics, the relationship between science fiction and linguistics is much closer than we thought.

본고는 한국어 생성 모델의 독성 텍스트 저항 능력을 검증하기 위해 'CVALUE' 데이터셋에서 추출한 고난도 독성 질문-대답 100쌍을 바탕으로 한국어 생성 모델을 위한 '100 K-Poison' 데이터셋을 시범적으로 구축했다. 이 데이터셋을 토대로 4가지 대표적인 한국어 생성 모델 'ZeroShot TextClassifcation'과 'Text Generation7 실험을 진행함으로써 현재 한국어 생성 모델의 독성 텍스트 식별 및 응답 능력을 종합적으로 고찰했고, 모델 간의 독성 텍스트 저항력 격차 현상을 분석했으며, 앞으로 한국어 생성 모델의 독성 텍스트 식별 및 웅대 성능을 한층 더 강화하기 위한 '이독공독(以毒攻毒)' 학습 전략을 새로 제안하였다.

본 연구에서는 민감한 개인정보의 유출과 남용 위험이 높아지고 있는 상황에서 정확한 개인정보 탐지 및 비식별화의 효율을 높이기 위해 개인정보 항목에 특화된 개체명 체계를 개발하였다. 개인정보 태그셋이 주석된 대화 데이터 4,981세트를 구축하고, 생성 AI 모델을 활용하여 개인정보 개체명 탐지 실험을 수행하였다. 실험을 위해 최적의 프롬프트를 설계하여 퓨샷러닝(few-shot learning)을 통해 탐지 결과를 평가하였다. 구축한 데이터셋과 영어 기반의 개인정보 주석 데이터셋을 비교 분석한 결과 고유식별번호 항목에 대해 본 연구에서 구축한 데이터셋에서 더 높은 탐지 성능이 나타났으며, 이를 통해 데이터셋의 필요성과 우수성을 입증하였다.

In this paper we discuss the contrastive nature of formalism and functionalism in linguistics. Though the mainstreams of linguistic analysis have been focused on the form and function, they have been challenged from each other's strong points. On the one hand, the formal description has been studied in the tradition of generative grammar. On the other hand, the functional nature has played a crucial role in the framework of language use. It seems undesirable to argue that there is one-sided bias toward any type of linguistic approach. I try to present a balanced view of these two contrastive approaches. We also argue that there should be a cooperative work in developing the mutual growth of linguistic theory.

끊임없이 재생산되는 혐오 표현의 정확한 탐지를 위해서는 혐오란 무엇인가에 대한 본질적인 이해가 필요하다. 본 연구에서는 화용론에서 사용되는 적정성 조건이라는 분석 틀을 활용하여 모델이 '혐오하기' 화행을 어떻게 인식하고 있는지 평가하고자 했다. 혐오 화행의 적정성 조건을 명제 내용 조건, 예비 조건, 성실성 조건, 본질 조건으로 나누어 분석하였으며, 이를 진위형, 연결형, 단답형, 논술형 문항으로 구성했다. 그 결과 모든 문항 유형에서 50점이 넘는 점수를 받았으나 비교적 고차원인 사고 능력을 측정하는 단답형과 논술형 문항 유형의 점수가 가장 낮게 나타났다.
