윤성재(Yoon, Sung-jae) 한국역사연구회 2013 역사와 현실 Vol.- No.87
The Chuseok holiday of Korea originated from the Ga"bae(嘉排) holiday of the ancient Shilla dynasty. But there might be some problems in directly connecting the Chinese Jungchu(中秋) holiday, which was essentially a holy service for the moon, with the Shilla Ga"bae holiday. Ga"bae celebration first appeared during Shilla king Yu"ri-wang"s reign. For an entire month, under the lead of two female members from the royal family, who also served as female priests, civilian females were specially recruited from the Six Bu units, in order to support the royal priests. Two teams were formed, and continued "weaving"(the "Jeok"ma" ceremony) in a form of a contest, and after the competition was ended they would present such products to the holy spirits through a memorial service, which was called the "Bu"jeong-je(部庭祭)" service. We believe the Ga"bae celebration was a festival that followed such task and service. The participants consisted of the royal females who led the two teams, and the civilian females from the Six Bu units who formed two groups and competed with each other. We can say that the Ga"bae festival was in fact a female festival. The place for this event, which was referred to as "Dae"bu"ji-jeong(大部之庭)" was not an ordinary space. It was a place for a holy religious activity, and also a sacred place for the Bu"jeong-je service. But according to the "Memorial Services" chapter of 『Samguk Sagi』 , the Bu"jeong-je service was not considered as a Confucian-style memorial service held at the Dynastic shrine or the founder king"s mausoleum. And it seems it was also different from other Shilla-specific services too. It could have been a service that belonged to the category of Miscellaneous Services("Jab-sa, 雜祀"). If it was indeed a traditional, folklore-based service, then it must have been a customary ritual designed to serve the objective of the royal family through a spiritual act of communicating with God. So, a Shaman priest(巫覡) with a specialized talent in the area would have led the services sometimes as well. Not only the two royal family females who led the contest and the service, but also the other females who were drafted from the Six Bu units, might have been selected to become part of a larger priest group. They must have taken on a variety of roles, but mostly they would have been ordered to weave textile products which were to be used in the Bu"jeong-je service, or to make clothes for the holy spirits(神衣) and enshrine them. Interestingly, the object to be receiving the service, and the subject who was arranging the holy memorial service, usually were regarded as one, as it was the general perception that the holy spirit would come down and superimpose itself upon the priest who was offering the service. In other words, the holy spirit overseeing the task of weaving was a female god, and a female priest serving that female God was literally offering the results of weaving.

윤성재(Yoon SungJae) 백산학회 2021 白山學報 Vol.- No.120
『어의촬요(御醫撮要)』은 1226년(고종 13)에 최종준(崔宗峻)이 왕실에서 비전(祕傳)되어 왔던 어의들의 처방 중 다방(茶房)에서 전해오던 방문을 2권으로 간행한 고려시대 의서이다. 이 책은 유실되어 전해지지 않으나 『향약집성방(鄕藥集成方)』과 『의방유취(醫方類聚)』 등에 인용되어 일부 내용을 알 수 있다. 『어의촬요』의 인쇄 배포를 통해, 종래 어의로 대표되는 왕실이 독점한 의료지식이 좀 더 널리 퍼지게 되었다. 하지만 의학 지식의 증가와는 별개로 약물을 구하는 것이 더욱 큰 문제였다. 왕으로부터 약을 받은 유공권의 사례나 용뇌를 권력자에게 받은 이규보의 사례는 약물의 확보 여부가 권력임을 보여준다. 이러한 흐름은 단오의 옥추단(玉樞丹)이나 납일(臘日)의 전약(煎藥)과 같이 의례화된 세시 풍속을 통해 권력 과시를 보여주는 형태로 유지되었다. 그러나 이런 의학적 혜택에서 배제되었던일반 민중들은 향약이라는 대체재를 마련하면서 의료생활을 발전시켰다. Eouichwaryo(御醫撮要) was published by Choi jongjun(崔宗峻) in 1226. He compiled two volumes of the royal family s prescription, which had been handed down by the Tea Office(茶房). This book is not handed down due to its loss, but it is cited in Euibangyoochui(醫方類聚) and Hyangyakjipsungbang(鄕藥集成方) to reveal some of its contents. Through the printing and distribution of this book, the royal family s proprietary medical knowledge, represented by the royal physician, has become more widespread. However, apart from the increase in medical knowledge, finding drugs was a bigger problem. The case of Yu Gongkwon(柳公權), who received medicine from the king and the other case of Lee Gyubo(李奎報), who received the borneol(龍腦) from the powerful man, shows that securing drugs is power. This trend was maintained in the form of showing power through ritualized seasonal customs, such as the Okchudan of Dano(端午) and the decoction of medicinal herbs of Nabil(臘日). However, people who were excluded from these medical benefits developed their medical lives by preparing alternative medicines.

Spoon is an essential tool for eating. It had been widely used on a daily life. However, all the tools are appear social characteristics of people who used these tools in pre-modern societies. Grave goods are emerged the social features and identity. I analyzed the bronze spoon in Gyeonggi area’s Koryo Dynasty tombs. Especially There was a change from the grave form in Koryo Dynasty. The corpse was leaved in the north and grave goods was reduced. But Bronzeware as like a Bronze mirror(銅鏡), Bronze bowl, was buried better than before. And porcelain was buried instead of earthenware. Specially grave goods was used things instead of new things Bronze spoon and chopsticks had buried from the late 11th century. Since the late 11th century, rich copper resources combined with processing technology of naturalized Khitan(契丹)’s people in Koryo Society. Bronzeware was a symbol of wealth to Koryo People, and was wanted to take to there grave. Since the 14th century bronze bowl was replaced with porcelain for grave goods. But bronze spoon still buried form 14th century to Joseon Dynasty.

정보통신기술(ICT)의 발전은 전통적인 제조 분야의 혁신을 가속화시키고 있고, 스마트팩토리로 불리우는 최첨단 공장에서는 각종 센서를 통해 실시간으로 데이터를 수집하고 있다. 이러한 수집된 데이터에 인공지능 기술을 적용하여 기계 고장 상황에 빠르게 대처하는 연구가 최근 들어 많은 관심을 받고 있다. 본 연구에서는 공작기계 스핀들의 고장 진단을 목적으로 인공지능 기술의 적용 가능성을 확인하기 위해 테스트벤치를 구축한 후 볼트를 이용하여 인위적으로 스핀들의 편심을 변화시킨 고장 데이터를 수집하였고, 분류(classification) 문제에 주로 사용되는 인공지능 모델 3종(CNN, LSTM, auto-encoder)을 학습하여 스핀들의 7가지 상태를 분류하는 정확도를 비교 분석하였다. 또한, 공작기계 도메인에 인공지능 기술을 효과적으로 적용하기 위해 필요한 데이터 수집 및 처리방법과 모델 개발 방법을 제안한다. The development of information and communication technology (ICT) is accelerating innovation in the traditional manufacturing sector. The smart factory which is a state-of-the-art factory collects data in real time through various sensors. Recently, researches on applying the artificial intelligence technology to these collected data to detect machine failures has gained a lot of attention. In this study, we built a test bench to check the possibility of applying the artificial intelligence technology for the fault diagnosis of the spindle of machine tools. We collected failure data by changing the off-center of the spindle using bolts. Further, we used artificial intelligence models (CNN, LSTM, and auto-encoder) to analyze the accuracy of seven types of fault classifications. In addition, the method of data collection, data process, and model development is proposed to effectively apply the artificial intelligence technology to machine tool domains.

Voltage-Frequency-Island NoC를 위한 테이블 기반의 고장 감내 라우팅 기법
윤성재(Sung Jae Yoon),이창림(Chang-Lin Li),김용석(Yong Seok Kim),한태희(Tae Hee Han) 대한전자공학회 2016 전자공학회논문지 Vol.53 No.8
반도체 공정 초미세화에 따라 에이징 (aging)과 공정 변이 (process variation)로 인한 칩에서의 물리적인 결함은 더욱 증가하고 있으며, 특히 금속 배선 스케일링 제한과 온 칩 데이터 통신량 증가에 따라 다수의 프로세서 코어로 구성된 네트워크-온-칩(Network-on-Chip, NoC)에서의 결함 감내 기법 연구가 활발히 진행되고 있다. 그러나 NoC에서 저전력 설계 기법으로 널리 채용되고 있는 VFI (Voltage-Frequency-Island)를 적용한 경우에서의 신뢰성 측면에 대한 연구가 부족한 실정이다. 본 논문에서는 신뢰성과 에너지 소모를 고려하여 VFI NoC에서 링크 고장이 발생하는 경우에도 정상적으로 통신을 유지할 수 있는 테이블 기반 라우팅 기법을 제안한다. 에너지 소모와 성능을 고려한 최적 경로와 고장 감내를 위한 우회 경로를 제공하며, 이때 우회 경로의 경우 필요한 최소한의 노드에만 라우팅 테이블을 저장하여 구현 복잡도를 완화하였다. 모의실험 결과를 통해 제안하는 기법은 전체 링크의 1%에서 고장이 발생하는 경우에도 정상적으로 통신함을 보였다. 또한 실시간으로 우회 경로를 탐색하는 고장 감내 라우팅 기법인 d² -LBDR에 비해 링크에 고장이 발생하는 경우 평균 15.9%의 에너지 소모가 감소함을 보였으며, 실행 시간 측면에서는 평균 0.8% 감소하는 것을 확인 할 수 있었다. Due to aggressive scaling of device sizes and reduced noise margins, physical defects caused by aging and process variation are continuously increasing. Additionally, with scaling limitation of metal wire and the increasing of communication volume, fault tolerant method in manycore network-on-chip (NoC) has been actively researched. However, there are few researches investigating reliability in NoC with voltage-frequency-island (VFI) regime. In this paper, we propose a table-based routing technique that can communicate, even if link failures occur in the VFI NoC. The output port is alternatively selected between best and the detour routing path in order to improve reliability with minimized hardware cost. Experimental results show that the proposed method achieves full coverage within 1% faulty links. Compared to d²-LBDR that also considers a routing method for searching a detour path in real time, the proposed method, on average, produces 0.8% savings in execution time and 15.9% savings in energy consumption.
