이가영 ( Kayoung Lee ) 이상근기념사업회 2016 이상근 연구 Vol.2 No.-

This study attempts to read Lee Sang Guen`s music in the historical context of 1980s of Korea. By considering the society of the 80s being one of the most turbulent eras of the 20th century of Korea, this study addresses various ways in which Lee reacts to, interact with, and engage this particular era. In particular, the study deals with Songs of song II written in 1988 with the text by Shin Dal Ja, focusing upon if these series of songs reflect the 80s. In order to examine the relation of 80s to Lee`s thoughts in general, and to Songs of song II in particular, this study traces Lee`s writing in the course of 50s, 60s, and 70s, arguing that Lee`s ideas, in one way another, demonstrate the ideas of essentialism that lead him not to see Korean and western art music in a subjective, balanced way. However, this paper argues that toward 80s, Lee appears to show his dissociation with the idea of essentialism. And this paper proposes that Songs of song II musically illustrates the kind of change that Lee underwent in the 80s.

The purpose of this study is to investigate fluoride release in the oral cavity from polymer adhesive tape which is NaF coated PVA. 45 healthy adults were divided into 3 groups by the type of topical fluoride applied: 60seconds taste$^{(R)}$ APF gel (group 1), FluoroDose$^{(R)}$ varnish (group 2) and NaF-PVA (group 3). Topical fluoride was applied to the facial surface of maxillary 12 teeth and unstimulated whole saliva was collected to measure fluoride release after 1, 3, 6, 12, 24, and 48 hours. Fluoride-sensitive electrode was used for measuring the fluoride concentration in the saliva samples. All three groups showed significantly higher value for fluoride concentration than the baseline after 1 and 3 hours (p < 0.05). After 6 hours, group 3 showed significantly higher fluoride concentration than the baseline (p < 0.05) and also showed significantly higher value for fluoride concentration than group 1 and group 2. Between group 1 and group 2, however, there was no significant difference statistically with respect to fluoride concentration value (p > 0.05). 연구의 목적은 인체 안정성이 입증된 고분자제제인 폴리비닐알코올(PVA, polyvinyl alcohol)로 얇은 박막을 제조하고 불화나트륨(NaF)을 첨가하여 불소를 함유한 고분자 접착 테이프(NaF-PVA)를 개발하여 피실험자의 구강 내에 도포 후 잔류하는 불소농도를 측정하였다. 이를 통해 제제 도포 전후의 타액 내 불소농도를 분석하여 불소를 함유한 고분자 접착 테이프의 치아우식증 예방효과를 간접적으로 평가하였다. 불소겔(60seconds taste$^{(R)}$, Group 1), 불소바니쉬(FluoroDose$^{(R)}$ varnish, Group 2)와 불소를 함유한 고분자 접착 테이프(NaF-PVA, Tiral product, Group 3)를 각각 15명씩 상악 치아 12개의 순면에 도포 후, 1시간, 3시간, 6시간, 12시간, 24시간, 48시간 후 비자극성 타액 내 불소농도를 불소이온전극을 이용하여 측정하였다. 도포 후 3시간까지 세 군 모두 불소제제 도포 전 농도보다 유의하게 높은 불소농도를 보였으며 3군의 경우 도포 후 6시간에서도 불소제제 도포 전 농도보다 유의하게 높은 불소농도를 보였다(p < 0.05). 도포 후 6시간에서 3군은 1군과 2군보다 유의하게 높은 불소농도를 보였고 (p < 0.05), 1군과 2군 사이의 유의한 차이는 없었다(p > 0.05).

심한 우식을 보이는 미성숙 영구치 치료에 있어서 치수생활력을 보존하는 것은 중요하다. 치수절단술을 시행 시 생체적합성이 있는 재료를 이용하여 치료함으로써 남아있는 생활력이 있는 치수를 보호하며 미성숙 영구치의 치근 성장을 도모할 수 있다. 혈소판 농축 섬유소는 환자의 혈액을 직접 채취하여 적용하기 때문에 생체적합성이 뛰어나며 다양한 성장인자를 함유하고 있어 치수생활력을 유지하고 미성숙 영구치의 치근 발육을 촉진시킬 수 있다. 본 증례에서는 심한 치아 우식증을 보이는 미성숙 영구치에서 치수절단술 시행 후 남아 있는 치수 상부에 혈소판 농축 섬유소를 적용하였다. 정기적인 검진 결과 미성숙 영구치의 치근 성장 및 정상적인 치아 주위 조직들이 관찰되었다. 향후 장기간의 임상적 관찰이 필요할 것이며 더 많은 임상 증례를 바탕으로 한 연구가 필요할 것이다. Preserving the pulp is important in the treatment of carious pulp exposure in young permanent teeth. Pulpotomy is a vital pulp therapy in which a portion of the coronal pulp tissue is surgically removed, and the remaining radicular tissue is covered with suitable material that protects the pulp from further injury and permits and promotes healing. It is important to develop biocompatible treatment directed at maintaining pulp vitality and increasing tooth longevity. Platelet-rich fibrin (PRF) has been referred to as a second-generation platelet concentrate. Two clinical cases in which PRF was applied as a medicament after pulpotomy of an immature permanent tooth are presented. After isolation, caries removal and pulpotomy with PRF was performed. A layer of mineral trioxide aggregate (MTA) was placed over the PRF, and the final restoration was performed. Postoperatively, the patient had no pain or discomfort, and follow-up radiographs revealed normal periodontal ligament space and trabecular bone pattern.

시판중인 불소 바니쉬의 불소이온 유리량 및 초기우식병소의 재광화 효과 비교

이가영,이상호,이난영,지명관,Lee, Kayoung,Lee, Sangho,Lee, Nanyoung,Jih, Myeongkwan 대한소아치과학회 2016 大韓小兒齒科學會誌 Vol.43 No.4

본 연구는 현재 시판되고 있는 불소 바니쉬 제품의 불소이온 유리 능력을 측정하고 이와 함께 정량 광 형광기를 이용하여 치질의 재광화 효과를 비교, 분석하였다. 평가하고자 하는 불소 바니쉬는 다음과 같은 6가지 제품을 대상으로 하였다; $FluoroDose^{(R)}$ (FD, Centrix Inc., USA), $Enamelast^{TM}$ (EL, Ultradent Product Inc., USA), $Clinpro^{TM}$ white varnish (CW, 3M ESPE, USA), $CavityShield^{TM}$ (CS, 3M ESPE, USA), V $varnish^{TM}$ (VV, Vericom, Korea), MI $varnish^{TM}$ (MI, GC, Japan). MI $varnish^{TM}$와 V $varnish^{TM}$에서 누적 불소이온 유리량과 재광화율이 가장 높게 나타난(p < 0.05) 반면 CS $varnish^{TM}$가 가장 낮은 누적 불소이온 유리량과 재광화율을 보였다(p < 0.05). Subjects of this study were : $FluoroDose^{(R)}$ (FD, Centrix Inc., USA), $Enamelast^{TM}$ (EL, Ultradent Product Inc., USA), $Clinpro^{TM}$ white varnish (CW, 3M ESPE, USA), $CavityShield^{TM}$ (CS, 3M ESPE, USA), V $varnish^{TM}$ (VV, Vericom, Korea), MI $varnish^{TM}$ (MI, GC, Japan). The amount of fluoride ion release was measured eight times during 168 hours to see change in accumulation with the course of time using a measuring instrument. And the remineralization rate was measured with Quantitative Light-induced Fluorescence (QLF). V $varnish^{TM}$ group and MI $varnish^{TM}$ group showed high remineralization rates with statistically significance while $CavityShield^{TM}$ group was the lowest rate of remineralization (p < 0.05). After that, several chosen samples were scanned through electron microscope (SEM). Demineralized enamel was observed as the number of enamel crystal was very small; enamel rods and crystals were highly protruding. Remineralized groups with fluoride varnishes show the decreasing tendency of the surface roughness compared to the demineralized enamel.

이가영,박정윤,Lee, Ka Young,Park, Jeong Yun 한국중환자간호학회 2018 중환자간호학회지 Vol.11 No.3

Purpose : This study investigates pediatric nurses' knowledge and attitudes regarding iatrogenic narcotic analgesic withdrawal symptoms management (INAWSM). Methods : In this cross-sectional study, 253 pediatric nurses working at a tertiary hospital in Seoul participated. Instruments were the inventory consisting questionnaires on 35 items knowledge and 12 items attitude for INAWSM. Further, descriptive statistics, t-test, and analysis of variance were used to evaluate the nurses' knowledge and attitudes. Results : The correct answers rate of knowledge toward INAWSM was 44.9%. With respect to the pediatric nurses' attitudes, the participants scored an average value of $2.83{\pm}0.25$ out of 4 points. The factor related to the knowledge and attitude level was age, pediatric nursing experience, educational experience, and educational needs. Conclusions : Results revealed that pediatric nurses had inadequate knowledge and attitude on INAWSM despite a compulsory education. Therefore, it is necessary to develop an efficient INAWSM educational program.

Naphthopyrone Glucosides from the Seeds of Cassia tora with Inhibitory Activity on Advanced Glycation End Products (AGEs) Formation

이가영,장대식,Yun Mi Lee,Jong Min Kim,Jin Sook Kim 대한약학회 2006 Archives of Pharmacal Research Vol.29 No.7

Three naphthopyrone glucosides, cassiaside (1), rubrofusarin-6-O-β-D-gentiobioside (2), and toralactone-9-O-β-D-gentiobioside (3), were isolated from the BuOH-soluble extract of the seeds of Cassia tora as active constituents, using an in vitro bioassay based on the inhibition of advanced glycation end products (AGEs) to monitor chromatographic fractionation. The structures of 1-3 were determined by spectroscopic data interpretation, particularly by extensive 1D and 2D NMR studies. All the isolates (1-3) were evaluated for the inhibitory activity on AGEs formation in vitro.
