Using the observation technique and in-depth interview, the current study compared various aspects of multicultural education between Korea and Canada and suggested the direction Korea's multicultural education needs to take. As a part of class curriculum, the researcher interviewed the representative of Ansan Foreign Center (AFC) and the president of the Kosian's House, a NGO for multicultural educations. The observations and experiences of the researcher were also used in this study. The results of the current study are as follows. First, multicultural education is provided for the minority group in Korea, whereas multiculturalism is included and taught for every student in Canada. In addition, the current multicultural education of Korea focuses on language and culture acquisition to help the students to adjust. Canada, on the other hand, focuses on accepting other cultures and ethnic equality, creating both identities as their ethnic origin and as Canadians. Second, in language educations, both countries had students enrolled in lower school years than their age. However, the differences occurred in terms of emotional support and availability of expert teachers. Third, comparing teacher's attitude towards multicultural education, Korean teachers were not free from perceiving the multicultural student as 'different', whereas Canadian teachers have been taught since little to consider multicultural students as Canadians, but accept their ethnic backgrounds. Based on the results, the current study suggested multicultural education program for the majority group, increase in number of expert language teachers and teaching assistants, and an education program to teach multiculturalism as part of an identity of humankind. The limitations and suggestions for future studies were provided afterwards.

Automatically detecting mentions of pharmaceutical drugs and chemical substances is key for the subsequent extraction of relations of chemicals with other biomedical entities such as genes, proteins, diseases, adverse reactions or symptoms. The identification of drug mentions is also a prior step for complex event types such as drug dosage recognition, duration of medical treatments or drug repurposing. Formally, this task is known as named entity recognition (NER), meaning automatically identifying mentions of predefined entities of interest in running text. In the domain of medical texts, for chemical entity recognition (CER), techniques based on hand-crafted rules and graph-based models can provide adequate performance. In the recent years, the field of natural language processing has mainly pivoted to deep learning and state-of-the-art results for most tasks involving natural language are usually obtained with artificial neural networks. Competitive resources for drug name recognition in English medical texts are already available and heavily used, while for other languages such as Spanish these tools, although clearly needed were missing. In this work, we adapt an existing neural NER system, NeuroNER, to the particular domain of Spanish clinical case texts, and extend the neural network to be able to take into account additional features apart from the plain text. NeuroNER can be considered a competitive baseline system for Spanish drug and CER promoted by the Spanish national plan for the advancement of language technologies (Plan TL).

Recognition of sign language is challenging due to the occlusion of hands, accuracy of hand gestures, and high computational costs. In recent years, deep learning techniques have made significant advances in this field. Although these methods are larger and more complex, they cannot manage long-term sequential data and lack the ability to capture useful information through efficient information processing with faster convergence. In order to overcome these challenges, we propose a word-level sign language recognition (SLR) system that combines a real-time human pose detection library with the minimized version of the gated recurrent unit (GRU) model. Each gate unit is optimized by discarding the depth-weighted reset gate in GRU cells and considering only current input. Furthermore, we use sigmoid rather than hyperbolic tangent activation in standard GRUs due to performance loss associated with the former in deeper networks. Experimental results demonstrate that our pose-based optimized GRU (Pose-OGRU) outperforms the standard GRU model in terms of prediction accuracy, convergency, and information processing capability.

In this paper, we propose a system that can detect the shape of a hand at high speed using an FPGA. The hand-shape detection system is designed using Verilog HDL, a hardware language that can process in parallel instead of sequentially running C++ because real-time processing is important. There are several methods for hand gesture recognition, but the image processing method is used. Since the human eye is sensitive to brightness, the YCbCr color model was selected among various color expression methods to obtain a result that is less affected by lighting. For the CbCr elements, only the components corresponding to the skin color are filtered out from the input image by utilizing the restriction conditions. In order to increase the speed of object recognition, a median filter that removes noise present in the input image is used, and this filter is designed to allow comparison of values and extraction of intermediate values at the same time to reduce the amount of computation. For parallel processing, it is designed to locate the centerline of the hand during scanning and sorting the stored data. The line with the highest count is selected as the center line of the hand, and the size of the hand is determined based on the count, and the hand and arm parts are separated. The designed hardware circuit satisfied the target operating frequency and the number of gates.

소프트웨어 아키텍쳐는 소프트웨어 시스템의 상위 수준 모델이다. 이러한 소프트웨어 아키텍쳐는 명료하고 엄밀한 표현을 위해 아키텍쳐 기술 언어(ADL)를 사용하여 기술된다. 하지만 대부분의 ADL들은 C2 스타일 ADL(C2SADL)처럼 소프트웨어 시스템의 개발에 필요한 요소들 중에서 특정한 관점만을 고려하여 정의되었거나 별도의 표기형식으로 배워야 하는 부담이 있기 때문에 아키텍쳐를 명세하는 언어로서 정착되지 못하였다. 반면 UML은 범용 모델링 언어로서 소프트웨어 개발의 전 과정에 일관된 표기형식과 폭넓은 지원도구들을 제공하고 있으므로 소프트웨어 개발을 위한 사실상의 표준 언어로 자리잡았다. 그러나 UML은 소프트웨어 아키텍쳐를 표현하도록 설계된 것은 아니기 때문에 UML을 사용하여 아키텍쳐를 표현하기 위해서는 UML을 확장, 변경하여야 한다. 본 논문에서는 UML2.0에 기반한 C2 아키텍쳐 모델링 언어 프로파일을 정의하였다. 정의된 C2 아키텍쳐 모델링 언어는 식당 예약 시스템을 모델링 하는데 사용되었다.

복지형 정보단말 장치로 청각장애인과 건청인사이의 커뮤니케이션을 지원하기 위한 수화 생성시스템이 개발되었다. 이 시스템에서는 신체의 각 부위의 움직임을 주목한Motion-Primitives에 기초로 하여 컴퓨터그래픽(CG) 애니메이션으로 수화 단어 동작을 생성하고 있다. 기존의 수화 생성시스템은 수화 단어를 생성할 때 손 모양이나 손과 어깨의 움직임을 제어하기가 어려워 수화 단어를 생성하는데 많은 시간이 소요되었다. 또한 수화 통역을 위해서는 수화단어가 5000단어 이상이 필요하기 때문에 수화단어 데이터 베이스를 구축하는 것도 큰 문제로 대두되고 있다. 따라서, 본 논문에서는 종래의 시스템보다 수화단어 구축에 있어서 다양한 움직임의 경로를 유연하게 만들수 있는 Motion-Primitives에 의한 새로운 시스템을 제안한다. 이 제안한 시스템을 적용하여 실제로 청각장애인을 대상으로 수화단어 100단어에 대하여 평가실험을 행한 결과 종래의 시스템으로 평균 76%의 인식 율을 얻을 수 있었던 것에 비하여 새롭게 제안한 시스템은 82%의 양호한 인식 율을 얻을 수 있었다.

The goal of this study is to examine whether the genre characteristics of newspaper articles are appropriately reflected in Korean language textbooks. For the purpose of this study, two corpora were built with 17 textbook articles and 60 newspaper articles respectively. The average sentence length and frequency of vocabulary in each corpus were measured. It was found that the sentences of articles in textbooks tended to have longer sentence length and more complicated structures than the articles in newspapers. For instance, sentences in the textbook articles had more verbal endings, such as conjunctive and transforming endings. On the other hand, in case of vocabulary representing 'timeliness', there was a high frequency of adverbs and nouns which were related to year, month, and time in actual articles, while it is found to be very limited in textbooks. Also, typical translative styles such as '-ko itta', '-e ttareumyun' were more prominent in textbooks than in newspaper articles. In the case of abbreviated and omitted form of particles, this was a characteristic that appeared only in actual articles because of the constraint of space. It is significant that this paper offers suggestions for the development of reading materials for Korean language education by revealing that the genre typology of actual newspaper articles is not adequately reflected in current textbooks.

최근 대규모 데이터 세트로 학습된 거대 언어 모델들의 뛰어난 성능이 공개되면서 큰 화제가 되고 있다. 하지만 거대 언어 모델을 학습하고 활용하기 위해서는 초대용량의 컴퓨팅 및 메모리 자원이 필요하므로, 대부분의 연구는 빅테크 기업들을 중심으로 폐쇄적인 환경에서 진행되고 있었다. 하지만, Meta의 거대 언어 모델 LLaMA가 공개되면서 거대 언어 모델 연구들은 기존의 폐쇄적인 환경에서 벗어나 오픈 소스화되었고, 관련 생태계가 급격히 확장되어 가고 있다. 이러한 배경하에 사전 학습된 거대 언어 모델을 추가 학습시켜 특정 작업에 특화되거나 가벼우면서도 성능이 뛰어난 모델들이 활발히 공유되고 있다. 한편, 사전 학습된 거대 언어 모델의 학습데이터는 영어가 큰 비중을 차지하기 때문에 한국어의 성능이 비교적 떨어지며, 이러한 한계를 극복하기 위해 한국어 데이터로 추가 학습을 시키는 한국어 특화 언어 모델 연구들이 이루어지고 있다. 본 논문에서는 오픈 소스 기반의 거대 언어 모델의 생태계 동향을 파악하고 영어 및 한국어 특화 거대 언어 모델에 관한 연구를 소개하며, 거대 언어 모델의 활용 방안과 한계점을 파악한다.

Chaucer's Troilus and Criseyde is a tale of love framed by an overarching pattern of death, set in the war-torn and doomed Troy, from which the lovers cannot separate their fate. Compared with Boccaccio's poem, the attention paid to death in Chaucer's version underlies his complex treatment of love. Above all, the language of death in Chaucer's poem provides the thread from which the entangled web of love is woven. Death together with desire pervades the language and rhetoric of the poem, prominent not only in the courtly love tropes, but also in the characters' asides and speeches. The prominence of these two concepts, desire and death, seem to be central to the various issues that the poem contains explicitly and implicitly. That is, two concepts are the basis for the breadth and depth of Chaucer's examination of love in light of the social and political realities of late fourteenth century England. The language of death in Chaucer's poem reflects the powerful influence on his imagination. With the devastation wrought by the plague and the changing fortunes of England in the war with France, Chaucer's world was once saturated in death, and one that could amply parallel the turn from prosperity to downfall. In particular, Chaucer's poem is suffused with the language of contagion and death in connection with desire. Troilus's lovesickness mimics the progress of a viral infection. Once breached, his body performs its newly compromised identity through fever, loss of appetite, and physical disintegration. On the other hand, Chaucer depicts Boccaccio's conventional portrait of Criseyde into a elaborate paramour of a pathogen. She is characterized as the contaminant that infects male hero. In addition, Criseyde is cast as sole earthly cure of illness that Troilus suffers from. In spite of Criseyde's role as nurturer and healer, Troilus longs for his own death and feels death clutching his heart. Finally, Troilus's love toward Criseyde is doomed to death.
