Currently, coronavirus disease 2019 (COVID-19) literature has been increasing dramatically, and the increased text amount make it possible to perform large scale text mining and knowledge discovery. Therefore, curation of these texts becomes a crucial issue for Bio-medical Natural Language Processing (BioNLP) community, so as to retrieve the important information about the mechanism of COVID-19. PubAnnotation is an aligned annotation system which provides an efficient platform for biological curators to upload their annotations or merge other external annotations. Inspired by the integration among multiple useful COVID-19 annotations, we merged three annotations resources to LitCovid data set, and constructed a cross-annotated corpus, LitCovid-AGAC. This corpus consists of 12 labels including Mutation, Species, Gene, Disease from PubTator, GO, CHEBI from OGER, Var, MPA, CPA, NegReg, PosReg, Reg from AGAC, upon 50,018 COVID-19 abstracts in LitCovid. Contain sufficient abundant information being possible to unveil the hidden knowledge in the pathological mechanism of COVID-19.

The aim of this study was to analyze contemporary sociocultural phenomena and values through characteristics of augmented reality (AR) digital fashion design. The research method included a literature review on the metaverse and augmented reality, combined with a case study using both quantitative analysis through big data text mining and qualitative analysis through constant comparison. Data analysis was conducted using Python-based open-source tools: First, 6,725 data entries were collected from AR digital fashion platforms and brands identified in articles from Vogue and Vogue Business containing keywords of 'augmented reality' and 'digital fashion. Second, text preprocessing involved stop word removal, tokenization, and POS-tagging of nouns and adjectives using the NLTK library. Third, top 50 keywords were extracted through term frequency (TF) and TF-IDF analysis, with results visualized using a word cloud. Fourth, characteristics of products' external design and internal concepts that contained top keywords were classified, with their value examined through repeated comparison. Results indicate that AR digital fashion design has the following characteristics. First, it embodies surreal fantasy through designs that mimic natural biological patterns using 3D scanning and modeling technology. Second, it presents a trans-boundary aspect by utilizing the fluidity of body and space to challenge vertical and discriminatory social structures. Third, it imagines a new future transcending traditional sociocultural concepts by expanding perceptions of space and time based on advanced technological aesthetics. Fourth, it contributes to sustainability by exploring alternatives for the fashion industry in response to climate change and ecological concerns.

This study proposed and examined a model in which perceived organizational support and leader-member exchange are linked to safety communication safety commitment, and accidents. In addition, a moderating effect of role overload in the relationship between safety communication and safety commitment and that of performance monitoring in the relationship between safety commitment to accidents. Data were collected from 193 workers in a railroad company. The results indicated that the goodness of fitness of the proposed model was acceptable. More specifically, both perceived organizational support and leader-member exchange were significantly related to safety communication and safety communication was, in turn, significantly related to safety commitment which was ultimately related to accidents. Also, the moderating effects of both role overload and performance monitoring were found. Implications of these findings for safety and the possible roles of variables in the organizational level are discussed.

Purpose - The purpose of this study is to elucidate the perception differences between CEOs and employees, and to derive a plan for improving performance by using theory of planned behavior (TPB) to enhance the competitiveness of SMEs exposed to various difficulties until recently. Research design, data and methodology - A total of 238 valid questionnaires were collected for CEOs and members of SMEs. In order to clarify the difference of perception, independent sample t-test and multi-group analysis using AMOS were conducted. Simple regression analysis and structural equation were used to confirm whether the theory of planned behavior was applied at the level of SME. Results - The CEO group is more aware of company's ethical responsibility activities and organizational support than the group of employees, and collectivism contributes more to organizational development than individualism tendency. Also, the theory of planned behavior is applied to the SME level as well. Conclusion - This study suggest that CEOs need to accept the pluralism of their members for the development of SMEs. In addition, it is necessary to form a consensus on ethical responsibility activities that corporations are performing by supporting diverse strategies and members' participation in management decision-making.

본 논문은, 긍정적 가중치와 부정적 가중치를 통해 표현되는 규칙에 기반을 둔 품사 태깅 모델과, 형태 소 unigram 정보와 어절 내의 카테고리 패턴에 기반하여 어절 확률을 추정하는 품사 태깅 모델의 장점을 취하고 단점을 보완할 수 있는 혼합 품사 태깅 모델을 제안한다. 이 혼합 모델은 먼저, 규칙에 기반한 품사 태깅을 적용한 후, 규칙이 해결하지 못한 결과에 대해서 통계적인 기법을 사용하여 품사 태깅을 한다. 본 연구는 어절 내 카테고리 패턴정보에 따른 파라미터 set과 형태소 unigram만을 이용해 어절 확률을 계산해 내므로 다른 통계기반 접근방법에서와는 달리 작은 크기의 통계사전만을 필요로 하며, 카테고리 패턴 정보를 사용함으로써 통계기반 접근 방법의 가장 큰 문제점인 data sparseness 문제 또한 줄일 수 있다는 이점이 있다. 특히, 본 논문에서 사용할 통계 모델은 어절 확률에 기반을 두고 있기 때문에 한국어의 특성을 잘 반영할 수 있다. 본 논문에서 제안한 혼합 모델은 규칙이 적용된 후에도 후보열이 둘 이상 남아 오류로 반환되었던 어절 중 24%를 개선한다.
