On the basis of the evidences that electrical stimulation could enhance proliferation and differentiation of bone cells and promote healing and regeneration of bone, this study was performed to investigate the effects of electrical stimulation on human periodontal ligament cells and gingival fibroblasts in vitro, which also have important roles in regeneration of periodontium, and to evaluate the potential of clinical application of electrical stimulation. Human periodontal ligament cells and gingival fibroblasts were primarily cultured from the root surface of extracted premolar and the adjacent gingiva without periodontal diseases. In control group, the cells ($5{\times}10^4$ cells/ml)were incubated only in Dulbecco's Modified Eagle's Medium contained with 10% fetal bovine serum. In test groups, electrical stimulation was given at the current intensity of $0.25{\mu]A$(test group 1), $1.0{\mu}A$(test group 2), and $2.5{\mu}A$(test group 3) for 12 hours to the same culture media with the control group. After 12 hour exposure of electrical stimulation, the cells were incubated for 2 and a half days(60 hours), and then each group of cells was analyzed for cell proliferation, protein level, and activity of alkaline phosphatase. The results were as follows ; 1. The Rate of cell proliferation of every test group increased significantly in both periodontal ligament cells and gingival fibroblasts, and in periodontal ligament cells, test group 3 showed significantly increased proliferation compared to the other test groups(p<0.05). 2. In the protein levels, neither periodontal ligament cell nor gingival fibroblast showed statistically significant differences between control and test groups. 3. The activity of alkaline phosphatase in periodontal ligament cells increased significantly in all test groups(p<0.05), but there were no significant differences between 3 test groups. In gingival fibroblasts, the activity of alkaline phosphatase increased significantly only in test group 3(p<0.05). From the above results, it is concluded that electrical stimulation may have beneficial effects on the regeneration of destructed periodontal tissue in regard of the stimulation of periodontal ligament cells and gingival fibroblasts as well as electrically stimulated bone formation that has been known, and that electrical stimulation may have the potential of clinical application.

유교 혼례의 절차와 상징성에 관한 고찰

이욱 ( Lee Wook ) 한국계보연구회 2011 한국계보연구 Vol.2 No.-

유교에서 혼례는 관례를 통해 어른임을 확인받은 사람이 부모에 게서 벗어나 다른 사람과 만나 새로운 터전을 마련하는 과정의 하나이다. 『의례(儀禮)』에 규정화된 혼례의 절차는 납채(納采),문명(問 名), 납길(納吉), 납징(納徵), 청기(請期),친영(親迎)의 여섯 가지 절차로 되어있다. 본고에서는 이 육례(六禮)를 중심으로 유교 혼례의 절차와 의미를 살펴보았다. 먼저 본고에서는 혼례의 목적을 이성(異性) 의 결합, 계승과 다산(多産), 통제와 분별(分別)이라는 세 가지 주제로 나누어 고찰하였다. 그리고 혼례의 절차를 역시 세 가지의 관점에서 살펴보았다. 첫째는 배우자 찾기라는 관점에서 본 선택의 과정이다. 여기서 의례의 주체는 신랑과 신부의 당사자가 아니라 그들의 부모이다. 납채, 문명, 납길, 납징 등 혼례의 주요 절차는 결혼의 상대를 선택하는 것이다. 청기 역시 혼례 날짜의 선택 과정이다. 이러한 선택의 의례화는 타자를 만남에 따른 불안과 희망을 동시에 보여준다. 둘째, 신랑과 신부의 관점에서 혼례를 바라보는 것이디-. 여기서는 친영의 과정 속에 내포된 합일의 상징이 중요시 되었다. 마지막으로 여성의 입장에서 신부가 친정아버님의 훈계로부터 시댁 사당에서 조상을 알현할 때까지의 입문 과정을 살펴보았다. In Confucianism, nuptials are the processes in which men and women, who were confirmed as adults through coming of age ceremony, escaped from their parents, met the opposite sex and set up new bases of life. The procedure of nuptials provided in『Uirye(儀禮)』 of six components: Napchae(納采), Munmyeong(問名), Napgil(納吉), Napjing(納徵), Cheonggi(請期) and Chinyeong(親迎). This study examined the purposes of nuptials in three topics: union between other sexes, succession & fecundity, and control & differentiation. The procedure of nuptials was also examined by three viewpoints. The first was the selection process in terms of seeking spouse. The main agents of selection process were not the bride and groom, but the parents of them. From Napchae, Munmyeong and Napgil to Napjing, the most of nuptials processes was spouse selecting. Similarly, Cheonggi is also the selection of date of nuptial ceremony. The formalization of selection shows at the same time the hope and anxiety that would arise when meeting other person. The second was watching nuptials from the viewpoint of bride and groom. Here, the symbolism of union connoted in Chinyeong process was importantly considered. Lastly, this study examined from the viewpoint of women the introduction processes starting with bride’s listening the discipline of her father ending at bride’s audience to the shrine of her groom.

壬辰倭亂中 鹽政의 展開와 性格

李旭(Lee Wook) 역사실학회 2002 역사와실학 Vol.24 No.-

The Chosun government entrusted private autonomy with the salt production and the sales. However, the outbreak of ImJinWaeRan(壬辰倭亂) compelled adjustment of these policies. The basic policy converted to a method it was so played, and the government produced salt directly, and to sell. It was YeomCheolSa(鹽鐵使) dispatched, or to have entrusted a local governor with the responsibility. However, the state-run commerce that a tyranny did not hold a change of the social structure rather resulted in a lot of abuse. It was due to Chosun government's to get a hasty policy in a financial supplement. And It was currently due to a local governor or GungBang(宮房), a nobleman(士大夫) getting profit through salt distribution. Afterwards, the salt policy of Chosun Dynasty was proceeded with course to eliminate participation of a government about Salt production or sale. Entrance to comment on direct intervention for a national commerce and industry achieved the mainstream. It is so done and emphasizes financial thrift and benevolence and righteousness and two characters can do a root the opening of a port has reality strong before, and an assertion having been reflected at policy or thoughts in agriculture.

대한제국의 성립과 명성황후(明成皇后) 국장(國葬)의 변화

이욱 ( Lee Wook ) 서울대학교 종교문제연구소 2018 종교와 문화 Vol.0 No.34

The death of Empress Myeongseong(1851-95), who was assassinated on August 20, 1895 (lunar calendar), was officially announced on October 15 (lunar calendar), over two months later. Begun at this point, state funerals for Empress Myeongseong proceeded through largely three stages. State funerals for Empress Myeongseong did not swerve from the overall framework of state funerals during the Joseon Dynasty (1392-1897). Continuity was maintained because the ideology and rituals of Confucianism were followed. As for elements of change that emerged amidst such a situation, some were extensions of changes during the latter half of the Joseon Dynasty while others stemmed from changes in government organization following the Gabo Reforms, import of Western elements, and political positions of the dominant groups. In addition, above all, changes arising from the establishment of the Empire of Korea had significant effects. A reinforcement of traditional rituals with the advent of a new era, all of this will form one axis for understanding the modern era in Korea.
