고미현,이수철 한국기술혁신학회 2022 기술혁신학회지 Vol.25 No.6

본 연구는 디지털 전환의 주요 기술인 디지털 트윈과 메타버스의 지식구조를 탐색하는 것을 주 목적으로 수행되었다. 학술논문은 대표적인 강건한 형식지 중 하나이므로 본 연구에서는 디지털 트윈과 메타버스 지식구조 탐색을 위해 WoS (Web of Science) 데이터베이스에서 학술논문 데이터를 수집하였고, 저자 키워드의 동시등장 관계를 통해 co-word network를 구축하였다. 구축된 co-word network에서 중심성 분석을 통해 주요 노드를 식별하고, 최대 신장트리(maximum spanning tree)를 추출한 후, 군집분석(clustering analysis)를 수행함으로써 디지털 트윈과 메타버스의 지식구조를 제시하였다. 그 결과 현재 지식구조 상으로는 디지털 트윈과 메타버스 사이에는 강한 직접 연계는 없는 것으로 파악되었으며, 메타버스 기술은 교육 영역에서 선제적 적용이 이루어지고 있는 것으로 분석되었다. 본 연구는 디지털 전환의 핵심 기술인 디지털 트윈과 메타버스에 대해 정량적 데이터를 기반으로 지식구조를 파악함으로써 관련 방향성을 제시한 점에서 그 의의가 있다.

As a result of the analysis, the main topics were presented in order of competence, virtue, character education promotion law, practice-based, community, citizenship, morality, care, integration, school violence, and etc. In terms of historical trends, the studies of character have been conducted in a variety of ways in various academic fields. In addition, research was shifting toward integration, practice, competence, and learner-based that strengthened emotions, social skills, and morality. Especially, Main topics in the academic field included competence, virtue, autonomy, creativity and teaching character, and the field of children education produced the most research topics Based on these results, knowledge structure of character studies, research trends, new Knowledge that is noteworthy, and program development were discussed.

디지털 전환 시대 우편물류 서비스 고도화를 위한물류 서비스 지식구조 탐색*

이수철,유태종 한국경영컨설팅학회 2024 경영컨설팅연구 Vol.24 No.2

This study aims to explore the knowledge structure of logistics services for the advanced development of postal logistics services in the era of digital transformation. Recent environmental changes represented by digital transformation and the new normal demand changes in postal logistics services. Postal logistics services, as a representative universal communication service, need to consider both efficiency and universality simultaneously. To explore the knowledge structure of logistics services, academic papers as verified explicit knowledge was collected through the Web of Science (WoS) database. Based on the collected data, a co-word network was constructed using the co-occurrence relationships of author keywords. Subsequently, the maximum spanning tree extraction and cluster analysis were conducted to present the knowledge structure of logistics services. The results revealed that research on the application of artificial intelligence for achieving efficiency in logistics services is actively underway, particularly with a high correlation between unmanned transportation systems and artificial intelligence. Furthermore, the high betweenness centrality of 'Internet of Things' nodes was confirmed as a prerequisite for the efficient operation of logistics systems. Environmental issues were emphasized in various clusters in the network structure. The concept of last-mile delivery, which is emphasized in the recent logistics industry, is strongly connected to concepts such as 'drone,' 'UAV,' and 'LiDAR.' The findings from the exploration of the knowledge structure of logistics services can contribute to the formulation of policy and business directions related to the advanced development of postal logistics services. This is particularly important in the context of digital transformation, where efficiency and universality need to be considered simultaneously.

텍스트 언어지식의 구조화 : 중간 표제어의 물리적 틀과 정보 유형 연구

서종석 ( Jong Seok Soh ) 한국외국어대학교 언어연구소 2013 언어와 언어학 Vol.0 No.59

This paper analyses various section heading titles and captures thematic information and typographic features related to them. Section headings are used to structure texts, and defined in terms of hierarchy. Our approach is based on the Contextual Exploration Method, which provides the framework for identifying specific semantic information contained in texts. The typographical devices such as capitalization, italic, bold font styles, etc. are employed to identify parts of the text as section headings. The ultimate aim of this analysis is to provide a conceptual tool using typographic features to detect sectional hierarchy information.

수학교사의 테크놀로지 교수 내용 지식(TPACK) 측정 도구 개발 및 타당화

이다희,황우형 한국수학교육학회 2017 수학교육 Vol.56 No.4

The purpose of this study is to develop and verify the TPACK measurement tool for middle and high school mathematics teachers in the Korean context. Also, by clarifying the relationship between subordinate factors of Mathematics teachers' TPACK, an attempt was made to provide suggestions on the designs and directions for the in-service and pre-service teacher education and the programs for improving mathematics teachers' TPACK in the future. In order to achieve this goal, TPACK factors of mathematics teachers were extracted by reviewing literature on PCK, MKT, and TPACK. Then, content validity, basic statistical survey, reliability verification, exploratory factor analysis, confirmatory factor analysis, and structural equation model verification were conducted sequentially. At first, preliminary analysis was carried out on 79 mathematics teachers, and 76 items excluding the items with extreme value and reliability were included in the basic statistical analysis. And secondly, an exploratory factor analysis was conducted on 376 mathematics teachers, and this instrument consisted of 7 subordinate factors(CK, PK, TK, PCK, TCK, TPK, TPACK) and 61 items. Also by conducting confirmatory factor analysis and structural equation model test with 254 mathematics teachers, the measurement tool was confirmed the validity and reliability through statistically significant analysis. Then, the importance of integrated knowledge was confirmed by looking at the relationship between the TPACK factors of in-service mathematics teachers. The integrated knowledge(PCK, TCK, TPK) has played a crucial role in the formation of TPACK rather than the knowledge of CK, PK, and TK alone. Finally, the validity of TCK was confirmed through the structural equation modeling of TPACK. TCK not only directly affected TPACK, but also indirectly through TPK. According to these affirmative results, this measurement tool is claimed to be suitable for measuring the factors of Mathematics teachers' TPACK, and also the structural equation model can be regarded as a suitable model for analyzing the structural relationship of mathematics teachers' TPACK.

텍스트 정보와 언어지식 : 주제구조표지 분석과 탐색

서종석 ( Jong Seok Soh ) 한국외국어대학교 언어연구소 2010 언어와 언어학 Vol.0 No.49

This paper analyses the linguistic markers identified as potential thematic introducers and captures the linguistic information related to them. Our approach is based on the Contextual Exploration Method, which states that semantic information associated to textual segments can be identified by linguistic primary marks and a set of clues that would help to minimize their ambiguity. The purpose of this paper is to detail how linguistic information concerning the thematic introducers (pour ce qui est de, en ce qui concerne, a propos de, au sujet de, etc.) is captured. The ultimate aim of this analysis is to provide a tool using linguistic expressions to extract thematic information.
