A Completely Cast-Free, Digital Workflow for Fabricating an Implant-Supported Prosthesis with a New Coded Healing Abutment

이주형 대한구강악안면임플란트학회 2019 대한구강악안면임프란트학회지 Vol.23 No.1

The BellaTek Encode System introduced an innovative concept of a healing abutment-level impression. As the coded healing abutment is unscrewed only at the placement session, the mucosal barrier at an implant is preserved and the clinical process is simplified. The laboratory process is also streamlined, as the entire process of a definitive dental implant abutment is outsourced and a dental technician fabricates only a definitive crown on a modified cast by robotic drilling or a stereolithography additive cast. However, potential errors may occur in the fabrication process of the casts. In addition, this system is available to only a specific implant system. This article describes a fully integrated digital workflow to overcome the limitations with a newly developed coded healing abutment. With the merging of advanced digital technologies, an implant-supported prosthesis can be accurately fabricated in an hour with minimized abutment dis/reconnection and no physical cast.

Using a Corpus Method to Understanding Universal-Design-Related Terms

이주형,이온순 한국공간디자인학회 2022 한국공간디자인학회논문집 Vol.17 No.6

(Background and Purpose) Growing numbers of elderly people and people with difficulties in mobility call for a change in the perception of design approaches related to the concepts of accessibility and usability for all people. One concern raised by the current use of terminology related to the concept of accessible design is the potential inappropriate usage of design terminology due to a lack of clear semantic distinctions among similar terms. Based on this observation, this study aims to provide a better understanding of the nature of various universal-design-related terms by reviewing and examining the usage of design terminology mentioned in scholarly papers by professional researchers and experts. (Method) This study employs corpus analysis methods, using the Python program. For the data collection, the study used universal-design-related keywords to search abstracts of academic papers published from 2003 to 2021 through Scopus and KCI. The keywords included, for example, ‘universal design’, ‘inclusive design’, ‘barrier free’, ‘accessible design’, ‘aging in place’, ‘adaptive design’, and ‘socially weak’. Based on the frequency analysis, Python was used to generate WordClouds and martic charts to visualize the usage and relationships of the frequently occurring words in the two corpora. (Results) The results suggest that the Korean context, universal-design-related words are largely related to the concepts of disability and age in public spaces, indicating that the application of the universal design approach focuses on addressing the needs of the specific populations of people with disabilities and older persons in public spaces (i.e., as opposed to, for example, housing) rather than on all people in all social contexts. In the foreign corpus, the universal-design-related words are largely related to concepts of people in general, regardless of physical ability or age, and of general accessibility, and indicates that such universal-design-related words might be most frequently applied to living environments, in particular housing. (Conclusions) The results of the analysis in this paper can be summarized as follows. First, Korean and overseas professional researchers’ perceptions of universal-design-related concepts might differ. In the Korean context, ‘disabled’ and ‘elderly’ seem the more important concepts. On the other hand, for non-Korean professional researchers, ‘people’ and ‘accessibility’ seem more important in the application of the universal-design-related approach. Second, Korean researchers have been interested in the application of universal design in the fields of public spaces and facilities, overseas studies have instead focused more on how universal design can be applied in various areas related to society, in particular living environments, buildings, housing, and human rights. This study provides theoretical implication. By re-examining the definition and principles of universal design, and distinguishing it from other related labels for this approach to design, the study’s findings call for further research to facilitate re-establishing or re-conceptualizing sub-elements of universal design.

The interaction of turbulent mixed convection and surface radiation in a three-dimensional channel with the heated blocks is analyzed numerically. Two blocks are maintained at high temperature and the other bottom and horizontal walls are insulated. S-4 method is employed to calculate the effect of the radiative heat transfer. The low Reynolds number k-$\varepsilon$ model proposed by Launder and Sharma is used to estimate the turbulent influence on the heat transfer enhancement. From above modeling, the effects of various channel specifications on the flow and heat transfer characteristics are investigated. The variables used for the present study are Reynolds number, block spacing, the channel height spacing for block and the emissivity. Average Nusselt numbers along the block surfaces are correlated and presented in terms of Reynolds number, emissivity and dimensionless geometric parameters. For the range of conditions in this study, average Nusselt numbers along the block surfaces are strongly influenced by the Reynolds numbers and channel height spacing for block but weakly influenced by the block spacing and the emissivity of the adiabatic walls.

플립러닝(Flipped Learning)을 통한 “거룩한만남”: 스마트 환경에서 기독교 대학 교양교육

이주형 연세대학교 신과대학 연합신학대학원 2018 신학논단 Vol.91 No.-

This paper is the initial theoretical construction to present the appropriateness of the flipped learning at liberal arts education in Christian universities. It takes account for the flipped learning as pedagogical method in college class and presents the way in which it could reshape the class environment prompting interactive communication and self-guided studies for college students. Inquiring the flipped learning and Christian liberal arts education dialectically, it made endeavor to enhance the efficiency and practicality of spirituality oriented character education as primary aim of Christian universities. This research presents the philosophical concept of education, “sacred encounter” as core for Christian spirituality oriented education and adopts it in liberal arts classes in Christian Universities. At last, it attempts to demonstrate its plausible embodiment by infusing or facilitating the flipped learning in constructive and reciprocal ways. 본 소고는 첫째, 기독교 대학의 교양교육이 지향하는 핵심개념을 영성적 인성교육을 중심으로 살펴볼 것이다. 다음으로, 전통적 방식의 교양교육이 직면하고 있는 대학교육의 스마트 환경을 살펴보며, 최근 적극적으로 도입되고 있는 플립러닝의 특징과 긍정적 효과와 한계를탐구할 것이다. 셋째, 기독교 대학의 교육철학으로 ‘거룩한 만남’이란 개념을 소개하면서, 기독교적 가치관과 세계관을 담지한 교양교육의 새로운 가능성을 고찰해보고자 한다. 마지막으로, 기독교 대학의 교양교육 환경에서 플립러닝이 어떤 방식으로 상호보완적으로 수용되고 활용될 수있을지를 고찰하며 그 가능성과 적합성을 탐구하고자 한다.

중고령자의 코로나19 이후 인터넷 이용량 변화와 일상생활만족도의 관계: 사회적 자본의 매개효과 분석

이주형,김기연 한국지역정보화학회 2022 한국지역정보화학회지 Vol.25 No.1

The purpose of this study is to investigate how changes in internet usage(PC/Mobile) after COVID-19 affect daily life satisfaction among Korean middle-aged and older adults and whether social capital mediates the relationship between changes in internet usage after COVID-19 and daily life satisfaction. We analyzed data of 2,300 adults aged 55 or older from the 「2020 Survey on Digital divide」 conducted by the National Inforamtion Society Agency. Both Baron and Kenny(1986)’s steps for mediation and the Sobel Test were conducted. Results showed that higher daily life satisfaction was found among middle-aged and older adults who were younger and had higher household income, higher internet usage(PC/Mobile), and higher level of social capital. In addition, while social capital partially mediated the relationship between changes in internet usage(PC) after COVID-19 and daily life satisfaction, the mobile case, social capital revealed to have a complete mediating role. This implies that social capital needs to be considered along with the level of internet usage as a way to improve daily life satisfaction of middle-aged and older adults. 본 연구는 중고령자의 코로나19 이후 인터넷 이용량 변화를 PC와 모바일 기기에서 각각 파악하고 이것이 일상생활만족도에 미치는 영향에 대해 살펴보았다. 더불어 코로나19 이후 인터넷 이용량 변화(PC/모바일)가 중고령자의 사회적 자본을 매개로 하여 일상생활만족도에 영향을 미치는지 살펴보았다. 본 연구에서는 한국지능정보사회진흥원(NIA)의 「2020년 디지털정보격차 실태조사」 자료를 활용하였으며, 연구대상자는 전국의 만 55세 이상 중고령자에 해당하는 2,300명이다. 분석자료는 SPSS 26.0을 사용하여 Baron&Kenny(1986)의 3단계 매개회귀분석을 실시하였으며, 사회적 자본의 매개효과에 대한 통계적 유의성은 Sobel Test를 통해 검증하였다. 분석결과, PC와 모바일 기기에서 모두 중고령자의 코로나19 이후 인터넷 이용량이 증가할수록, 사회적 자본 수준과 가구 월 평균 소득이 높을수록, 연령이 낮을수록 일상생활만족도가 더 높은 것으로 나타났다. 또한, 사회적 자본의 매개효과를 분석한 결과, PC에서의 코로나19 이후 인터넷 이용량 변화와 일상생활만족도의 관계에서 사회적 자본은 부분매개효과를 가지는 것으로 나타났다. 반면, 모바일 기기에서의 코로나19 이후 인터넷 이용량 변화와 일상생활만족도의 관계에서 사회적 자본은 완전매개효과를 가지는 것으로 나타났다. 이를 통해 중고령자의 일상생활만족도를 향상시키기 위한 방안으로 활발한 인터넷 이용 수준과 더불어 사회적 자본을 고려할 필요가 있음을 알 수 있다.

天圓地方의 천문학적 차원에서 본 干支의 曆法과 과학적 세계 -河圖의 圖像學的 원리-

이주형,이진무 동아시아고대학회 2023 동아시아고대학 Vol.- No.70

This study begins by interpreting the meaning of the circular heaven and rectangular earth, a time and space concept in East Asian tradition. The sexagenary cycle, invented in the ancient Shang Dynasty, became an essential tool for calculating time coordinates. Since ancient times, the development of the calendar system has not only informed the precise timing of sowing and harvesting required by agricultural societies but also provided the necessary baseline for human life. Everything in the universe leaves a trajectory of its existence in the framework of space and time corresponding to the four-dimensional world. Therefore, by understanding the principle of the circular heaven and rectangular earth, which is comparable to a priori knowledge handed down from the Neolithic period, it is possible to understand the four directions of the east, west, north, and south, which are the time and space coordinates. To identify ancient information, it is necessary to pay attention to the folktales passed down in the ancient societies where there were no letters, although excavating various relics from that era is a representative means. In the folktale, 10 suns, Fuso and Yakmok, Hyeonjo, Hehwa, and Tanggok appear, providing a five-way spatial framework. Because various fortune-telling techniques were popular at the time, the shell of the turtle or the shoulder bone of the animal served as a valuable resource that provided clues to the five directions. In addition to the combination of bottled water and holy water, the river, which explains the spatial structure of the five rooms, can elucidate the spatial arrangement structure of the five rooms as well as the iconographic principles of the circular heaven and rectangular earth. 본 논문에서는 동아시아 전통의 시공간 개념인 천원지방의 의미를 어떻게 해석할 것인가에서 출발한다. 고대 상나라 시대에서 출발한 60갑자는 시간의 좌표를 계산하는 중요한 도구이다. 고대로부터 내려오는 역법 체계의 발달은 농경사회에 필요한 파종과 추수의 정확한 시기를 알려줄 뿐만 아니라 인간 삶에 필요한 기준선을 제공해주었다. 우주 만물은 4차원 세계에 해당하는 공간과 시간의 틀 속에서 삶의 궤적을 남긴다. 이런 이유로 신석기 시대에서부터 전해 내려오는 선험적 지식에 비견되는 천원지방의 원리를 통해 시간의 좌표인 역법과 공간의 좌표인 동서남북의 사방 체계를 파악하고자 하였다. 고대의 정보를 알아내기 위해서는 그 시대의 각종 유물, 유적발굴이 대표적 수단이긴 하나 문자가 없던 고대 사회에는 구전되어 전해 내려오는 설화에도 관심을 가질 필요가 있다. 설화에는 10태양, 부상, 약목, 현조, 희화, 탕곡 등이 출현하여 오방의 공간 틀을 제공한다. 각종 점복술이 유행하던 시기이기 때문에 상대에는 특히 거북의 껍데기나 동물의 어깨뼈 등에 기록된 갑골문이 오방의 관념에 관한 단서를 제공해주는 좋은 사료가 된다. 오방의 공간구조를 설명한 하도는 생수와 성수의 조합과 더불어 오방의 공간적 배치구조를 이해할 수 있으며 더 나아가 천원지방의 도상학적 원리를 이해할 수 있다.
