The Ministry of Education is attempting to cultivate artificial intelligence convergence education teachers and establishment of artificial intelligence convergence education majors at graduate schools. However the scale for measuring and evaluating teachers’ abilities remains insufficient. Hence this study developed and validated the teaching competency scale of artificial intelligence convergence education for teachers. We derived the initial items through literature analysis, and we conducted Delphi surveys twice for 22 expert panels in related fields. Owing to the Delphi survey, items were maintained, modified, and deleted according to the qualitative opinions of experts and minimum value standard of the content validity ratio proposed by Lawshe(1975). Consequently, to validate the initial question, we conducted two surveys and a factor analysis for 213 teachers nationwide. Through factor analysis and reliability analysis, we derived two competency groups and six sub-factors “artificial intelligence convergence education understanding competency.” and “artificial intelligence convergence education instructional design competency.” “curriculum/class reconstruction competency.” “artificial intelligence-based learning environment development competency.” and “class reflection and improvement competency.” This study is significant in that it diagnoses teachers’ artificial intelligence convergence education teaching competency and presents a direction for teacher retraining and pre-teacher education.

Court paintings of military soldiers wearing black conical hats with the top folded and draping back from the late Joseon period are quite common. This type of hat has been known as Jeongeon, and was worn by soldiers, but no additional details have been revealed. Recently, however, as similar artifacts among the Korean collections of overseas museums have been discovered and surveyed, there emerges a need to find the proper term for them. Old documents, paintings, museum collections with regard to Jeongeon were thus compared and analyzed in this research. The purpose of this study is to broaden and deepen the understanding of military uniforms by revealing who wore them, how they were worn, as well as the materials and manufacturing methods used to make them. Jeongeon was a hat worn by soldiers, together with Hyeopsu, Gwaeja or Hoeui, and navy Jeondae in the late Joseon dynasty. Originally, it was exclusively produced for and worn by members of the Hullyeondogam. But it gradually came to be worn by soldiers of many other units. Soldiers with Jeongeon are primarily seen in paintings of the 18th and 19th centuries. The method of making Jeongeon was researched through examining historical records and museum collections. First, paper was attached to black fabric, then folded vertically so that the left and right sides overlapped in three layers. The center lines of the back were brought together, and then the upper side was sewn horizontally. The hat was decorated with red rectangles and gold curve lines, and the back was decorated with five gold vertical lines. The structure and characteristics of the artifacts in overseas museum collections are mostly consistent with literature and painting records. This research will contribute to the reproduction of Jeongeon and reenactment events in the future.

This study was conducted to investigate changes on the quality characteristics of Prunus davidiana sugar extracts (PSEs) by processing conditions. The PSEs were prepared by extraction with commercial sucrose at 4°C or 25°C for 9 months with or without a pressure plate. The quality characteristics of PSEs were analyzed for Bxo, pH, total acidity, Hunter color value, alcohol content, polyphenol content, DPPH radical scaveging activity, and free sugar content. Bxo increased significantly while pH decreased with increased storage period (p<0.05). The PSEs stored at 4oC scored lower than those stored at 25oC for total acidity, alcohol content, and polyphenol contents. The PSEs with pressure plate possessed lower alcohol content and higher polyphenol content and DPPH free radical scavenging activity than those without pressure plate. The sucrose content in PSEs decreased with increased storage period, while glucose and fructose contents increased. These results indicate that by increasing storage period, sucrose in PSEs is decomposed into glucose and fructose, and the quality characteristics of PSEs such as total acidity, alcohol, and polyphenol content depend on processing conditions.

This study explores how Korean high school students write English short essays in internet-based writing spaces. Participants consist of 12 Korean high school students. Among them, four students as a control group wrote two short essays with a paper and pencil at the beginning and end of the data collection procedure. Along with the two pre- and post- writing, the other eight students wrote for four more weeks either in an internet bulletin board or in facebook using a computer. They posted short essays online and exchanged peer feedback. The results indicates that the facebook writers exchanged more feedback with more peers compared to the bulletin board writers, suggesting that facebook could facilitate student interactions. However, the facebook writers showed the tendency to write less. Their online essays included fewer arguments and supporting details, and often omitted background and closing statements. The facebook writers' post-essays remained shorter in length and simpler in organization than their pre-essays as well as the other two groups' paper-pencil ones. The bulletin board writers, however, did not show any visible differences between their online and paper-pencil essays. Overall the study results suggest that different online writing spaces may differentially influence the ways that English learners write online, and English learners' online writing practices may also influence their later paper-pencil writing. Suggestions for future research and teaching of English writing are provided as well.

고대에서 중세에 이르기까지 동서양의 문화가 교차하던 실크로드의 중심에 위치한 우즈베키스탄 사마르칸트에서 아프라시압 궁전지벽화가 1960년대 발굴되어 학계의 주목을 받아왔다. 특히, 7C 소그디아나 왕국 바르후만 왕의 즉위식이 그려진 서벽에서 고대 한국인으로 추정되는‘조우관’을 쓴 두 인물이 발견되어 당시 국제적 정세와 문화적 특징을 살필 수 있는 중요한 사료로 활용되고 있다. 현재 아프라시압 역사박물관에 소장되어 있는 이 벽화는 사방으로 각기 다른 내용의 그림이 그려져 있고, 그것만이 가진 문화적 특성과 요소들이 내재되어 있음에도 불구하고 이를 활용한 스토리텔링과 문화콘텐츠의 개발은 없었다. 따라서 본 연구의 목적은 고대 한국인이 그려진 아프라시압 궁전지 벽화의 서벽 그림을 기반으로 한 문화콘텐츠와 캐릭터 개발과 활용방안을 모색하고자 한다. 이를 위하여 직접 현장을 방문하여 조사한 자료는 물론이며 기타 관련 학술자료들을 수집하였다. The wall paintings of the Afrasiab Palace in Samarkand, Uzbekistan, located at the center of the Silk Road where the culture of the East and the West crossed from ancient times to the Middle Ages, have been unearthed in 1960s and attracted attention from academia. In particular, two characters wearing a Korean ancient hat (Jougwan), who were considered to be ancient Korean, were found in the western wall. The wall depicted the Coronation of King Barfuman of Sogdiana Kingdom in 7th century. It is being used as an important feed for studying the international situation and cultural characteristics at that time. This mural, which is now in the Historical Museum of Afrasiab, contain four different paintings at each side, and has its own cultural characteristics and elements. Nevertheless, there has been no development of storytelling and cultural contents using it. The purpose of this study is to find out how to develop and utilize cultural contents and characters based on the paintings of west wall of Afrasiab palace. To this end, we visited the museum and investigated the mural as well as surveyed many academic materials.

커피 전문점 텀블러 공유 서비스 활성화 방안 연구

박가영,김승인 한국디지털정책학회 2020 디지털융복합연구 Vol.18 No.1

The purpose of this study is to suggest ways to reduce plastic use, one of the main culprits of environmental pollution around the world. Recently, the use of disposable cups at a domestic cafe has not been effective due to growing the number of stores and cafe in various brands. Cafes recommend the use of tumblers as a solution to the problem, but actual there are not many users in cafe. I need to investigate the problems of tumbler use and individual opinions through the first phase is FGI (Focus Group Interview). In the second phase, I investigate similar services, which are currently implemented in domestic and overseas, as a case study. The results showed that although similar services are offered in domestic, the focus is on tumbler sharing, which is somewhat insufficient for convenience provided when using cafes. Through this study, I hope to provide convenience and voluntary environmental protection by proposing a plan to activate Tumbler sharing services for cafe and users. 본 연구는 전 세계적으로 환경오염의 주범 중 한 가지인 플라스틱 사용을 줄이기 위한 방안을 제시하는 것이 목적이다. 최근 국내 커피 전문점에서 사용하는 일회용 컵 사용은 매장 수와 다양한 브랜드 커피 전문점이 늘어남에 따라 큰 실효성을 거두지 못하고 있는 상황이다. 카페에서는 이 문제의 해결 방안으로 텀블러 사용을 권장하고 있지만, 실제 사용자는 미미한 것으로 나타나 있다. 이에 본 연구는 1차로 FGI(표적집단면접법) 실험을 통해 텀블러 사용의 문제점과 개인의 견해를 조사하였다. 2차로 현재 국내·외에서 시행하고 있는 유사 서비스를 사례조사로 진행하였다. 그 결과 국내의 경우 유사 서비스를 제공하고 있지만, 텀블러 공유에 초점을 두고 있어 카페를 이용 시 제공되는 편의성이 다소 미흡한 것으로 나타났다. 이 연구를 통해 커피 매장과 사용자를 위한 텀블러 공유 서비스 활성화 방안을 제안하여 편의성 제공과 자발적 환경보호의 계기가 되길 기대한다.
