Deaf mutism (a hearing-impaired person and speech disorders) communicates using sign language. There are difficulties in communicating by voice. However, sign language can only be limited in communicating with people who know sign language because everyone doesn't use sign language when they communicate. In this paper, a finger language translation system is proposed and implemented as a means for the disabled and the non-disabled to communicate without difficulty. The proposed algorithm recognizes the finger language data by leap motion and self-learns the data using machine learning technology to increase recognition rate. We show performance improvement from the simulation results.

This study is for investigating strategy of associating loanwords to original words of Korean language learners. Loanwords have often been thought as easily learnable because the knowledge of the original word is assumed to be helpful in discovering the meaning. But there is much phonological, morphological and semantic transforming in accepting original words in Korean, and therefore, it is not easy to connect Korean loanwords to the original words. In this study, the awareness of loanwords and competence of associating Korean loanwords to the original words of advanced Korean language learners from China are investigated. As a result, the awareness of loanwords is remarkably lower than the awareness of non-loanwords. And, the competence of association also was very low with 17.9% of successful association. This means the learners have difficulty in inferring the meaning of loanwords by connecting that to original words.

Treating genomes just as languages raises the possibility of producing concise generalizations about information in biological sequences. Grammars used in this way would constitute a model of underlying biological processes or structures, and that grammars may, in fact, serve as an appropriate tool for theory formation. The increasing number of biological sequences that have been yielded further highlights a growing need for developing grammatical systems in bioinformatics. The intent of this review is therefore to list some bibliographic references regarding the recent progresses in the field of grammatical modeling of biological sequences. This review will also contain some sections to briefly introduce basic knowledge about formal language theory, such as the Chomsky hierarchy, for non-experts in computational linguistics, and to provide some helpful pointers to start a deeper investigation into this field.

Objective : Functional magnetic resonance imaging (fMRI) is frequently used to localize language areas in a non-invasive manner. Various paradigms for presurgical localization of language areas have been developed, but a systematic quantitative evaluation of the efficiency of those paradigms has not been performed. In the present study, the authors analyzed different language paradigms to see which paradigm is most efficient in localizing frontal language areas. Methods : Five men and five women with no neurological deficits participated (mean age, 24 years) in this study. All volunteers were right-handed. Each subject performed 4 tasks, including fixation (Fix), sentence reading (SRI. pseudoword reading (PR), and word generation (WG). Fixation and pseudoword reading were used as contrasts. The functional area was defined as the area(s) with a t-value of more than 3.92 in fMRI with different tasks. To apply an anatomical constraint, we used a brain atlas mapping system, which is available in AFNI, to define the anatomical frontal language area. The numbers of voxels in overlapped area between anatomical and functional area were individually counted in the frontal expressive language area. Results : Of the various combinations, the word generation task was most effective in delineating the frontal expressive language area when fixation was used as a contrast (p<0.05). The sensitivity of this test for localizing Broca's area was 81 % and specificity was 70%. Conclusion : Word generation versus fixation could effectively and reliably delineate the frontal language area. A customized effective paradigm should be analyzed in order to evaluate various language functions.

ChatGPT가 등장한 이후 다양한 거대 언어 모델(Large Language Model, LLM)이 등장하였고, 이러한 LLM을 목적에 맞게 파인튜닝하여 사용할 수 있게 되었다. 하지만 LLM을 새로 학습하는 것은 물론이고, 단순 튜닝만 하더라도 일반인은 시도하기 어려울 정도의 많은 컴퓨팅 자원이 필요하다. 본 연구에서는 공개된 LLM을 별도의 학습 없이 사용하여 zero-shot 프롬프팅으로 이진 분류 태스크에 대한 성능을 확인하고자 했다. 학습이나 추가적인 튜닝 없이도 기존 선학습 언어 모델들에 준하는 이진 분류 성능을 확인할 수 있었고, 성능이 좋은 LLM의 경우 분류 실패율이 낮고 일관적인 성능을 보여 상당히 높은 활용성을 확인하였다.

A new distributed/parallel algorithm simulator, DASim(Distributed Algorithm Simulator), is proposed in this paper. The idea is to ease the task of design, analysis and implementation of distributed algorithms. A small high level language has been proposed for the purpose. Through this non-language specific high level language, the users are spared from the tedious details about how to program distributed or parallel algorithms. Further, visualization of these algorithms are pretty helpful to understand behaviors of these algorithms.

In this Paper we consider non-deterministic finite Rabin-Scott's automata. We define special abstract objects, being pairs of values of states-marking functions. On the basis of these objects as the states of automaton, we define its edges; the obtained structure is considered also as a non-deterministic automaton. We prove, that any edge of any non-deterministic automaton defining the given regular language can be obtained by such techniques. Such structure can be used for solving various problems in the frames of finite automata theory.

In the past, Korean English language learners focused on knowledge of grammatical structures. Thus Korean trained instructors, who focused on explaining the grammar structures, were seen as being preferable for teaching in EFL (English as a foreign language) classrooms. However, with the focus changed to speaking capability Koreans now desire 'fluent' English more than 'accuracy' seeing if possible (Mottos, 1997). Current study has been concerned about the issue of how non-native learners of English perceive the difference between native teachers (NTs) and non-native teachers (non-NTs) of English in the context of ELT classroom. The study explores the issues and problems the followed and how non-NTs can enhance teaching practice of speaking and listening lessons through multimedia application.

This research, we will begin our analysis of the types of research example of designers by the linguistic studies of products form. Specially, we had a mind to generate the linguistic concept of products form by the linguistic relations between tools and thinking, and analysed how activate the roles of form language in linguistic and non-linguistic areas. We understood the relations of design process about idea generation, same means of interpretation of form and the generation of form concept, by using of the roles of form language made in design process. We showed the research examples of Enzo Mari and the origins of form language in view point of design history. Also, we classified the form linguistic concerns of designers and scholars interested in design areas by dividing various factors in view point of language. Finally, through the process of this classification, the researches of form language call for further study, as more the examples of detailed design practises and the individualized form language of products than systematic researches and abstract theories about products, and emphasized this viewpoint, we suggest a going-on research theme, the individualized products' differences of form language and concerns viewpoint of inter-culture, the concept generation of form language of products can be inter-coexistent.

In this study, using data completed in the 11th year of the Panel Study on Korean Children, discourse management, situational adjustment and application ability, communication intention, and non-verbal communication were investigated by the child pragmatic language checklist tool in the field of cognitive and language development. It is to find a significant influence by analyzing the relationship between the factors of the observed variables on the latent variables of communication. The subject of this study is 4th grade elementary school students in 1,392 households, excluding 36 non-respondents to the language development question, out of 2150 households in the 11th year of the Panel Study on Korean Children(2018) data, 1428 households excluding 722 households who did not participate in the survey. As a result of the study, it was found that the total effect, direct effect, and indirect effect among the three latent variables except for communication intention were all significant in the effect analysis of the research model. Specifically, not only did nonverbal communication have a direct effect on discourse management ability, but also the indirect influence mediated by situational control and application ability was significant in the relationship between nonverbal communication and discourse management ability. As a result, it was found that the higher the non-verbal communication and situational adjustment and adaptation ability, the higher the discourse management ability.
