Sign language has completely different meaning depending on the direction of the hand or the change of facial expression even with the same gesture. In this respect, it is crucial to capture the spatial-temporal structure information of each movement. However, sign language translation studies based on Sign2Gloss2Text only convey comprehensive spatial-temporal information about the entire sign language movement. Consequently, detailed information (facial expression, gestures, and etc.) of each movement that is important for sign language translation is not emphasized. Accordingly, in this paper, we propose Spatial-temporal Keypoints Centered Sign2Gloss2Text Translation, named STKC-Sign2 Gloss2Text, to supplement the sequential and semantic information of keypoints which are the core of recognizing and translating sign language. STKC-Sign2Gloss2Text consists of two steps, Spatial Keypoints Embedding, which extracts 121 major keypoints from each image, and Temporal Keypoints Embedding, which emphasizes sequential information using Bi-GRU for extracted keypoints of sign language. The proposed model outperformed all Bilingual Evaluation Understudy(BLEU) scores in Development(DEV) and Testing(TEST) than Sign2Gloss2Text as the baseline, and in particular, it proved the effectiveness of the proposed methodology by achieving 23.19, an improvement of 1.87 based on TEST BLEU-4.

This paper presents a development of a mobile sign language recognition system for daily communication of deaf people, who are sign dependent to access language, with hearing people. The system observes their sign by a cap-mounted camera and accelerometers equipped on wrists. To create a real application working in mobile environment, which is a harder recognition problem than lab environment due to illumination change and real-time requirement, a robust hand segmentation method is introduced and HMMs are adopted with a strong grammar. The result shows 99.07% word accuracy in continuous sign.

In order to increase the productivity of software, the research to reduce the total cost in software development environments is working, Considerable time is wasted waiting for a changed program in program development, however smell the change, to be edited and compiled and executed. In case of partial change, we need incremental interpreter for reexecuting the changed parts and its affected parts, In this paper, we implement the incremental interpreter by using analyzing dynamic semantics at execution time, We define a new IMPLO(IMPerative Language with Object) language using EBNF(Extended Backus Naur Form) notation and then, design and implement the incremental interpreter of this language by using action equations to describe the dynamic semantics.

This study pointed out the reality that many novice Korean language teachers who lack rater training are scoring the learners' writing skill. The study performed and analyzed a case where pre-service teachers were educated in order to explore the possibility of promoting rater training in a Korean language teacher training course. The pre-service teachers majoring in Korean language education at the graduate school scored TOPIK compositions and were provided feedback by the FACETS program, which were further discussed at the rater meeting. In three scoring processes, the raters scored with conscious of own rating patterns and showed positive change or over correction due to excessive consciousness. Consequentially, ongoing training can improve rating ability, and considering the fact that professional rater training is hard to progress, the method composed of FACETS analysis and rater training revealed positive effects. On the other hand, the rater training including native Korean and non-native(Chinese) speakers together showed no significant difference by mother tongue but by individual difference. This can be interpreted as a positive implication to the rating reliability of non-native speakers possessing advanced Korean language abilities. However, this must be supplemented through extended research.

This study aims to improve the accessibility and efficiency of sign language education for both hearing impaired and non-deaf people. To this end, we developed VR realistic sign language education content that integrates hand tracking technology and conversational AI. Through this content, users can learn sign language in real time and experience direct communication in a virtual environment. As a result of the study, it was confirmed that this integrated approach significantly improves immersion in sign language learning and contributes to lowering the barriers to sign language learning by providing learners with a deeper understanding. This presents a new paradigm for sign language education and shows how technology can change the accessibility and effectiveness of education.

Built-up environments by humans are cultural byproducts which combine social ideology and architectural paradigm. The process of modernization in the Western countries has the characteristic of decisive paradgm based on materialism. Therefore, environmental design in modern world failed to focus on the essential features of humanity which are the subject of space and replaced it for objective and unilateral architectural environments, instead. Environment without supporting the human psychological and complicated behaviorism is as same as the hardware without the vitality. under these regards, this study will cover the design approach of pattern language as a design method of environment design. The purpose of design approach by pattern language lies in creating the space of flexibility, adaptability and strong vitality. It is summed up as humanization in space and it helps the user to verbalize individualized space language for their own. The range and method of in the study attribute to the pattern language of Christopher Alexander and a researcher' method on them. In premise that human behavior ought to the multilateral and indefinite under rapid change of circumstances in modern world, th study tried to find the design method stimulating creative behavior of human being.

This study analyzes a language network of Science and Technology Basic Plan, which is the basis for science and technology policy in Korea, for the next Science and Technology Basic Plan. Language network analysis was adopted for a quantitative approach measuring the trend of policies. Several techniques such as keyword analysis, language network map analysis, quantitative characteristics analysis and keyword-related major-word analysis have been performed. Results show that there are common policies emphasized by all Science and Technology Basic Plans in the past, and there are also specific policies emphasized in each period of the Science and Technology Basic Plan. These specific policies come from a 'change of times' when the Science and Technology Basic Plans were established, as well as the philosophy of the national government.

This study explores the lexical-semantic structure of derived causative verbs in Korean based on Pustejovsky(1995)'s Generative Lexicon Theory (GL). Morphological causative verbs are derived from their root stems by affixing ‘-i, -hi, -li, -gi’ in Korean and the meanings of derived predicates are closely related to the meanings of their root verbs. In particular, the change of the ARGUMENT STRUCTURE by morphological derivation leads to the change of the EVENT STRUCTURE. The ARGUMENT STRUCTURES of derived causative verbs include a causer argument, which is added to the ARGUMENT STRUCTURE of their root verbs by means of the causative derivation. Their EVENT STRUCTURE has a headed process related to a causer and its result is the event which their root verbs denote. This approach can also suggest that the (in)directness of causative is dependent on is the semantics of its root verb.

The purpose of this study is to examine possible improvements of operation of sign language interpreter qualification system through looking into specific perceptions of sign language interpreters and Deaf sign language interpreters in the field and Deaf people who use interpretation service on current sign language interpreter qualification system through focus group interview. As a result of the thematic analysis, three high-level categories were derived for each group, and as a result of recombining them, 'change to a qualification system in which sign language interpreting competency and expertise can be recognized' and 'improvement to a qualification system based on Korean Sign Language and Deaf culture' been sorted out. Based on the above research results, 'establishment of a permanent institution in charge of management and operation of sign language interpreter qualification tests', 'reorganization into a qualification system that reflects the professionalism, level and experience of sign language interpreters', 'all test questions and exam procedures are conducted mainly in sign language', 'a system in which the Deaf take the lead', and 'enactment of a code of ethics for sign language interpreters and Deaf interpreters' were suggested.

The purpose of this study is to examine aspects and causes of the change and disappearance in the Gangneung dialect vocabulary about costume. A typical example of linguistic factors that influence the change of costume vocabulary is competition with the standard language. However, costume as culture has a more powerful effect than linguistic factor. For example, the following factors lead to the disappearance: the disappearance of the referent, the inherent characteristics of the costume, the introduction of the new culture, and the change in values about costume.
