Self-efficacy was found to play a partial mediating role in the relationship between transformational leadership and learning outcomes. Therefore, it was confirmed that the transformational leadership of polytechnic professors had a significant direct and indirect impact on students

메타버스기반 LLM을 활용한 생성형 AI의 구현

A metaverse is a virtual convergence environment that promotes inclusiveness and diversity by maintaining social relationships among users through avatars and engaging them in various cultural activities. Because everyday activities can be maintained the same in a metaverse environment, the transmission, exchange, and sharing of useful and accurate information among members in the metaverse environment has become important. Additionally, the desire and requirements of members to obtain the desired information through conversations with avatars in a metaverse are increasing; the number of these cases is also increasing. Accordingly, in this study, we redesigned and implemented the structure of the metaverse platform at Korea Polytechnics such that generative AI based on an LLM could be utilized on the metaverse platform. By presenting experimental examples according to the implementation, we confirmed that an AI-based service could be provided that configured the LLM and generated answers in the metaverse. In future research, we plan to apply various generative AI models to the metaverse platform, present a customized model through a comparative analysis, and continue research on implementing our LLM model.

머신러닝기반 메타버스플랫폼 고도화 모델 설계에 관한 연구

Metaverse is a space where communication and interaction similar to those in the real world are possible and new experiences can be pursued through the provision of various contents and services. Owing to the recent advancements in the application of artificial intelligence (AI), Metaverse is expected to expand. The convergence of metaverse and AI overcomes the limitations of communication, resolves difficulties in creating space, and maximizes the use of internal and external data. In this study, we present the status of existing studies implemented within the Metaverse Platform virtual campus of Korea Polytechnic and the design of an advanced model that enhances interaction using machine learning such as the latest GPT technology and LLM. We propose to provide an LLM-based interactive internal information search service to improve the user environment by efficiently utilizing internal data and communicating in natural language. In future studies, we will focus on the detailed design of domain data capable of general-purpose services and implementation of the advanced model designed in this study. Thereafter, we intend to design and construct our own reliable LLM model and perform performance evaluation through with external LLM models.

챗GPT기반 메타버스플랫폼 모델 설계에 관한 연구

Interactivity is the most critical factor in the success of metaverse platforms, which can provide a unique user experience through interaction with digital avatars and engagement in a shared space. As a conversational artificial intelligence (AI) service, ChatGPT is considered a promising approach to dramatically improve the quality of interactions with computational agents on existing metaverse platforms. The ability of large language models (LLMs) to understand and respond to human communication can be expected to enable more immersive and realistic experiences. Therefore, in this study, we developed a computational model to enhance interaction with AI agents on a virtual campus on the Korea Polytechnics University metaverse platform by using ChatGPT. In future research, we plan to create an LLM with unique domain data related to Korea Polytechnic University and the National Competency Standards (NCS) along with industrial and personal data and implement the model by fine‑tuning a specially designed architecture with a pretrained framework. We plan to apply this system to the virtual Polytech Metaverse Campus for testing and monitoring. We will also perform quantitative and qualitative analyses based on advice from technical experts and the results of objective evaluations.

미래형 직업교육을 위한 메타버스기반 환경 연구

The prolonged COVID-19 pandemic has changed offline-oriented education by increasingly employing online methods. Although in the early days, the metaverse was operated to be used as a one-time event rather than for education, it is now gaining attention as a new virtual learning space that interacts with reality. In this study, the metaverse platform Poly Meta and content use cases built by Korea Polytechnics were analyzed.
 Based on this, we intend to go beyond the usage of the metaverse in general education and further develop metaverse environmental requirements and content in a direction necessary for vocational education. In future research, quantitative and qualitative analysis will be performed on the metaverse platform’s usability and accessibility and on the effect of applying it to vocational education and training

A Study on the Collocations in English Class in Korea Polytechnics Focusing on Textbook and Classroom Activities

A lot of interest is in vocabulary teaching and learning, and most research focuses on individual words. Learners have been encouraged to learn individual words and make sentences by inserting them into extended grammatical structures. Although learners successfully learn grammar and a lot of individual words, they often produce awkward grammatical sentences. This is because of their lack of collocation competence. Learners have relatively few chances to encounter typical word sequences repeatedly. Thus, they are more likely to translate from their unacceptable general vocabulary knowledge. A collocation is a relationship between two words or groups of words that often go together and form a common expression. Some combinations sound natural to native English speakers, but other combinations may be unnatural and sound wrong to native speakers. Learning collocation is a crucial part of learning the vocabulary of a language and of acquiring fluency. This paper aims to suggest a few activities accessible to Korea Polytechnics’ English class to help Korea Polytechnics’ students improve their collocation competence instead of just memorizing as many words as possible.

반응형 수업모델 개발과 적용사례 연구 － 한국산업기술대학 <한국문학의 이해>를 중심으로

이 글의 목적은 대학생의 인문·인성 교육에 효과적인 ‘문학’ 관련 교과목 수업모델을 기획하는 데에 있다. 즉 학생들이 ‘문학’ 수업을 통해 인문학을 수용하고, 나아가 인문학에 주체적으로 반응하여 자신의 학습 경험을 표현할 수 있도록 <한국문학의 이해> 교과목 수업모델을 구성해 보는 것이다. 21세기 지식기반 사회에서 학생들은 주어진 상황과 과제에 맞는 적절한 지식과 정보를 선별하고 활용하는 능력을 갖추어야 한다. 이런 능력과 태도를 기르는 방향으로 교육 내용이 변화해야 하는데, 이때 부각된 것이 핵심역량 개념이다. 역량기반 대학교육은 학습자 중심의 새로운 형태의 교육 패러다임을 요구하고, 본 연구는 그러한 새로운 교육 패러다임에 부응할 수 있는 수업모델을 개발하여 적용 사례를 검토하였다.<BR> 대학에서 ‘문학’은 ‘인문·인성’(Re:Humanity) 교육을 실시할 수 있는 매우 중요한 교과목이다. 본 수업모델로 수업을 진행하게 되었을 때 기대효과는 다음과 같다. 첫째, <한국문학의 이해> 수업은 철저히 학습자 중심으로 수업이 운영되고, 그 과정에서 학생들은 스스로 인문·인성 교육을 체득하게 될 것이다. 둘째 현대, 단편, 소설 중심의 문학 작품의 독서와 토론은 인문학의 바탕이 미흡한 대학생들에게 감성지수를 향상시키고, 아울러 ‘나’와 ‘타인’에 대한 이해의 폭을 넓혀 궁극적으로는 공감 능력을 신장시킬 것이다. 셋째 학생들은 자신의 지식과 경험을 바탕으로 텍스트를 읽고, 그 과정에서 자신의 삶을 성찰할 기회를 갖게 된다. 뿐만 아니라 텍스트 속에 존재하는 다양한 갈등과 솔루션의 예를 제공함으로써 문제해결능력을 갖추게 할 것이다. 넷째 본 모델을 적용하여 교과목을 개선했을 경우, 학습자들은 문학작품 속에 내포된 무궁한 상상력을 자신의 전공 영역과 결합하여 좀 더 창의적이고 융합적인 사고 역량을 확보할 수 있을 것으로 기대한다.

Oxyresveratrol의 기원, 생합성, 생물학적 활성 및 약물동력학

Department of Chemical Engineering and Biotechnology, Korea Polytechnic UniversityAbstract Oxyresveratrol (trans-2,3',4,5'-tetrahydroxystilbene) has been receiving increasing attention because of itsastonishing biological activities, including antihyperlipidemic, neuroprotection, antidiabetic, anticancer, antiinflammation,immunomodulation, antiaging, and antioxidant activities. Oxyresveratrol is a stilbenoid, a type of natural phenol and aphytoalexin produced in the roots, stems, leaves, and fruits of several plants. It was first isolated from the heartwood ofArtocarpus lakoocha, and has also been found in various plants, including Smilax china, Morus alba, Varatrum nigrum,Scirpus maritinus, and Maclura pomifera. Oxyresveratrol, an aglycone of mulberroside A, has been produced by microbialbiotransformation or enzymatic hydrolysis of a glycosylated stilbene mulberroside A, which is one of the major compoundsof the roots of M. alba. Oxyresveratrol shows less cytotoxicity, better antioxidant activity and polarity, and higher cellpermeability and bioavailability than resveratrol (trans-3,5,4'-trihydroxystilbene), a well-known antioxidant, suggesting thatoxyresveratrol might be a potential candidate for use in health functional food and medicine. This review focuses on theplant sources, chemical characteristics, analysis, biosynthesis, and biological activities of oxyresveratrol as well as describesthe perspectives on further exploration of oxyresveratrol.Keywords: oxyresveratrol, stilbenoid, biosynthesis, biological activity, phamacokinetics
