The purpose of this study was to assess the effects of wavelength and intensity of light curing units on the curing of composite resin. The wavelength and intensity of nine units were evaluated with Optical Multichannel Analyzer and Radiometer. Two-part split stainless steel mold with a cylindrical hole-3.0mm in diameter, 6.0mm in hgieht-was prepared. After placing a Mylar strip between two parts, 100 specimens were made by inserting each of four composite resins into the mold and irradiating for 20 seconds with five light units alternatively. The curing depths were measured by scraping method and evaluated by two-way ANOVA. And Vicker's hardness measurements were made on the longitudinally sectioned surface at 0.5mm interval. The results were as follows: 1. Visilux 2 showed a narrow spectral band within the effective wavelength in initiating polymerization and the highest intensity. Translux showed the diffuse spectrum of wavelength and the lower light intensity. 2. Visilux 2 showed the highest curing effect in any composite resin and then followed by Optilux, Efos 35, Heliomat and Translux. (p < 0.01) 3. Durafill showed the deepest curing depth in any light unit and then followed by Bisfil M, Silux and Heliosit. (p < 0.01). 4. Maximum hardness values showed 0.1mm and 0.5mm under top surface and then gradually decreased with depth.

야담집 소재 신라 및 경주 이야기 연구-『天倪錄』, 『雜記古談』, 『東稗洛誦』을 중심으로 -

이채경 동국대학교 WISE(와이즈)캠퍼스 신라문화연구소 2013 新羅文化 Vol.41 No.-

Yadam(野談) was the best literary genre in the literary history of late Choseon dynasty. In this paper, I researched the Silla(新羅) and Gyeongju(慶州) story in Yadam collections. Especially there were focused by 『Cheonyerok(天倪錄)』written by Im Bang(任埅), 『Jabgi-godam(雜記古談)』written by Im Mae(任邁), 『Dongpaeraksong(東稗洛誦)』written by No myeong-heum(盧命欽). I selected six stories in this collections. For example, there were <Kimyousin(金庾信)> and <Maeng taoist[孟道人]> and <a foolish admiral[궤짝 提督]> on 『Cheonyerok』, <a medical witch[醫巫]> and <two sword women[女俠]> on 『Jabgi-godam』, <a beggar[乞客]> on 『Dongpaeraksong』 etc. Silla was the first ancient nation to unify three nations in Korean history, and Gyeongju was an ancient capital about thousand years in Silla dynasty. As a result of study, I knew that they had understanding about the Silla dynasty and Gyeongju people in the late of Choseon dynasty. The first, <Kimyousin> and <Maeng taoist> stories showed us unification of three nations and signs of decadence. Two stories contained all historical facts. The second, Silla Son officialdom appeared on <a medical witch>, Gyeongju sword man appeared on <two sword women>. I knew that Gyeongju was godlike person's living through two stories. The third, <a foolish admiral> and <a beggar> stories had two Gyeongju official dancing girls. They were very wise, so showed us her wit[機智] and discerning eye[知人之鑑]. I knew that they satirized on social conflict and against misgovernment through two stories. There were mixed literary fiction in this stories. In short, Silla and Gyeongju story in Yadam collections were harmonized with historical fact and literary fiction. Also there were people's historical mind and actual spirit in this stories.

18세기 송사담의 서사 양상과 특징

이채경 대동한문학회 (구.교남한문학회) 2023 大東漢文學 Vol.77 No.-

야담은 조선후기 한문서사에서 단연 돋보이는 장르이며, 18세기는 순수야담의 전성기였다. 본고는 18세기에 등장한 송사담의 서사 양상과 특징을 연구한 결과물이다. 18세기 송사담은 다양한 사건과 그 경제적・제도적・사회적 배경을 담아내는데, 공물 대납권을 둘러싼 사기사건과 남녀의 음행을 다룬 무고사건 및 가문의 명예를 중시한 살인사건 등이 있다. 또 야담 저자가 송사에서 주목한 대목과 그것이 어떠한 이야기로 펼쳐지는지 살펴보면, 국기일에 문서를 위조하는 범죄모의 과정과 신체적 특징을 이용해 범죄를 해결하는 과정 및 범죄를 재수사하는 과정에 검시를 통해 원통함을 해소하는 등으로 서사가 전개되었다. 이러한 분석을 거쳐 도출한 18세기 송사담의 서사적 특징은 일상 경험을 평어로 부록하고, 구체적인 증거로 사건이 해결되며, 현실과 비현실을 넘나들며 송사가 벌어진다는 사실이 확인되었다. 이는 18세기 송사담만의 전개 양상과 서사적 특징이라 단언하기 어렵지만, 송사를 다룬 이야기가 당시 처음으로 등장했으며, 차후 송사담에 거의 실리지 않은 것으로 보아 특정 시기에 한정된 이야기라고 할 수 있다. Yadam is a genre that stands out among the Chinese narratives of the late Joseon Dynasty, and the 18th century was the heyday of pure Yadam. This paper is the result of a study of the narrative aspects and characteristics of lawsuit story, which appeared in the 18th century. The lawsuit story of the 18th century contains various incidents and their economic, institutional, and social backgrounds, including a fraud case surrounding the right to pay tribute, a false accusation case dealing with adultery between a man and a woman, and a murder case that focused on family honor. We also looked at the parts that the author of Yadam paid attention to in the lawsuit and what kind of story it unfolded. For example, the narrative unfolded through the process of simulating a crime by forging documents on National Memorial Day, solving a crime using physical characteristics, and resolving the resentment through an autopsy during the process of reinvestigating the crime. Through this analysis, it was confirmed that the narrative characteristics of the 18th century lawsuit story are that crimes in everyday life are narrated, cases are solved with specific evidence, and lawsuits take place across reality and unreality. It is difficult to say for certain that this is the development pattern and narrative characteristic unique to lawsuit story in the 18th century. However, considering that the story dealing with the lawsuit appeared for the first time at the time and was rarely included in subsequent lawsuit story, it can be said to be a story limited to a specific period.

의원급 의료기관 간 경쟁이 진료행태에 미치는 영향 - 유ㆍ소아 급성중이염 중심 융합연구 -

이채경,서원식 한국융합학회 2018 한국융합학회논문지 Vol.9 No.1

이 연구는 의원 간 경쟁이 급성중이염 총진료비와 항생제처방률에 미치는 영향을 분석하였다. 건강보험심사평가원 2015년 유·소아 급성중이염 평가 자료를 활용하여 기초통계, 상관분석, 회귀분석을 실시한 결과는 다음과 같다. 첫째, 총진료비와 의원 간 경쟁지수는 시·구·군별 큰 격차를 보였으나, 항생체처방룰은 차이를 보이지 않았다. 둘째, 의원 간 경쟁은 총진료비에 통계적으로 유의한 영향을 미쳤다. 셋째, 의원 간 경쟁은 항생제처방률에 통계적으로 유의한 영향을 미치지 않았다. 향후 연구에서 의료기관 경쟁정도가 진료행태에 미치는 다른 요인을 규명하기 위해 재진비율, 방문당 진료비 등에 대한 추가 연구가 필요하다. This study analyzes the impact of competitions clinics on the total treatment cost and anti-biotics prescription rate. The result of implementing the basic statistics, correlations, and regression analysis by facilitating the evaluation data by Health Insurance Review & Assessment Service in 2015 for acute otitis media in children is shown as follows. First, there is a significant difference for each si-gun-gu for the competition index between total treatment cost and clinics, but there is almost no significant difference for the anti-biotics prescription rate. Second, competition in clinics has statistically important impact on the total examination cost And, third, competition in clinics has no statistically important impact on the anti-biotics prescription rate. There is a need for additional studies on re-examination rate, treatment cost per visit and so forth in order to clarify other factors of competition for medical institutions impacting on the physician behavior in the future studies.

어린이(0-12세) 손상환자의 재원일수에 미치는 요인 분석: 퇴원손상심층자료를 중심으로

이채경 국제문화기술진흥원 2023 The Journal of the Convergence on Culture Technolo Vol.9 No.3

This study was conducted to analyze factors affecting the length of stay in children with injuries by determining relationships between length of stay and characteristics of children(aged 0 to 12) with injuries. 7,804 patients aged 0 to 12 who participated in the Korea Nation Hospital Discharge In-Depth Injury Surveys, got a diagnosis of sequelae of injuries and of other consequences of external causes(S00-T98), and were discharged between 1 January 2016 and 31 December 2020 were investigated. A frequency analysis, independent samples t-test, and ANOVA were performed. Also, to identify factors affecting the length of stay, a regression analysis was performed. The average length of stay for the patients investigated in this study was 5.5 days. The length of stay for school-age children(aged 7 to 12) and children who had either public or private coverage was higher than that for preschoolers(aged 0 to 6) and children who didn’t have public or private coverage, respectively. The length of stay for children admitted to a hospital in a rural area(Jeolla-do or Gyeongsang-do) was higher than that for children admitted to a hospital in a metropolitan area and the length of stay for children admitted to a hospital that had 100-299 hospital beds was relatively long. However, children who first visited a hospital for outpatient care stayed relatively short in hospital and children who had been burned or injured in traffic crashes stayed relatively long in hospital. Children who got a secondary diagnosis and had a principal procedure or who died after being discharged were in hospital for a long time. The findings of this study shall be useful, as they identified characteristics related to the length of stay for Korean children with injuries and factors that determine the length of stay for those children by analyzing the national dataset, or more specifically, the data from the Korea National Hospital Discharge In-Depth Injury Surveys. The risk of child injuries can be easily reduced by taking actions to prevent them and providing safety education programs. The present study has provided essential baseline data for the provision of aggressive care for child injuries and the establishment of a range of policies for child injury prevention. 이 연구는 어린이(0-12세)손상 환자의 특성에 따른 재원일수의 관계를 규명하여, 어린이손상 환자 재원일수에 미치는 요인을 분석하고자 시행하였다. 조사대상은 퇴원손상심층조사 자료에서 2016년 1월1일부터 2020년 12월31일까지 퇴원한 환자 중 0-12세 이하이며, 주진단이 손상 및 사고의 외인(S00-T98)인 환자 7,804명이었다. 분석은 빈도분석 및 독립표본 t-검정, ANOVA 검정을 실시하였다. 재원일수에 영향을 미치는 요인을 알아보고자 회귀분석을 시행하였다. 연구대상자의 평균재원일수는 5.5일 이었다. 학령기(7-12세)기 아동이 학령전기(0-6세)보다 재원일수가 길었으며, 진료비 지불방법이 의료급여 및 기타보험 환자가 재원일수가 길었다. 의료기관 소재지가 수도권보다 비수도권(전라도, 경상도)일 때, 병상규모가 100-299병상인 경우 재원일수가 길었다. 내원경로는 외래인 경우 재원일수가 짧았고, 손상기전이 운수사고, 화상인 경우 재원일수가 길었다. 부진단이 있고, 주수술을 시행한 경우 재원일수가 길었으며, 퇴원후 방향이 사망인 경우 재원일수가 길게 나타났다. 이 연구는 전국 단위 자료인 퇴원손상심층조사 자료를 이용하여 우리나라 어린이 손상환자의 재원일수의 특성 및 결정요인을 파악하였다는 점에서 의의를 갖는다. 또한, 안전교육 및 예방 활동만으로도 발생을 줄일 수 있는 어린이 손상의 관련 요인 대한 적극적인 치료와 다양한 예방정책 마련을 위한 기초 자료를 제공했다는 점에서 의의가 있다.

『三國遺事』와 스토리텔링―동서양 이야기의 비교를 중심으로

이채경 국제언어문학회 2018 國際言語文學 Vol.- No.39

In this article, I comparatively analyzed storytelling aspect of Yadams and myths from the east and the west. Furthermore, I judged value and stature of 『Samgukyusa』 as a original form of storytelling. Firstly, <A tale of Geotaji> was passed down to <A tale of Hwapojang> as a Yadam and was changed its sort from strange story to story of making fortune thereby reflecting social aspect of those days. Also <A tale of Geotaji> has similar story development with <Story of Perseus> from Greek myths. It shows contents about repaying favor and making relationship presenting different sentiments and cognizances of the east and the west. In sequence, <A tale of Kimyusin> had been altered to new tale by transmission including <A tale of King Michu Jukyeopkun> which could found in history. It originally was a story about protection of country by king Michu and Kimyusin but thereafter it had been changed to story about right ideals of Kimyusin as a confucian scholar. Lastly, <A tale of King Kyeongmun> has similar substance to tale of king Midas from Greek myths. Both tales based on emotional pressure about revealing secrets and object's ecological features. Furthermore, especially <A tale of King Kyeongmun> emphasizes king's 'ear' as a organ of listening public sentiment. Therefore, 『Samgukyusa』 is a repository of storytelling that could discover transmission relation between tale and Yadam furthermore can find common features between western myths. And it is evaluated as a original form of Korean storytelling. 본고에서는 『삼국유사』에 실린 이야기를 중심으로 동서양 說話와 野談 및 神話의 스토리텔링 양상을 비교 분석하고, 스토리텔링 原形으로서 『삼국유사』의 가치와 위상을 가늠해 보았다. 먼저 설화 <거타지 이야기>는 야담으로 전승되어 <화포장 이야기>를 낳았고, 스토리 성격이 당대의 사회상을 반영한 奇異談에서 致富談으로 바뀌었다. 또 <거타지 이야기>는 그리스 신화 <페르세우스 이야기>와 유사한 스토리 전개 양상을 보였는데, 동서양의 서로 다른 정서와 인식을 반영한 報恩談과 結緣談을 이루었다. 다음으로 설화 <김유신 이야기>는 역사서에 나오는 미추왕 죽엽군 이야기를 포함해 야담에 전승되어 새로운 이야기로 변개되었으며, 당초 미추왕과 김유신의 護國談에서 이후 儒者로서 김유신의 면모를 강화한 正義談의 양상을 보여주었다. 마지막으로 <경문왕 이야기>는 그리스 신화 <미다스 왕 이야기>와 흡사한 내용인데, 두 이야기는 모두 비밀과 발설에 대한 인간의 심리적 압박과 사물의 생태적 특징이 기저에 깔려 있으며, 특히 <경문왕 이야기>는 王者가 民心을 듣는 신체기관으로서 ‘귀[耳]’를 강조한 스토리텔링이라고 해석되었다. 따라서 『삼국유사』는 우리나라 설화와 야담의 전승관계를 밝히고, 서양의 신화와도 유사성을 발견할 수 있는 스토리텔링의 寶庫이자 原形으로 평가된다.
