남재철(Nam Jae cheol,南在澈) 대동한문학회 2015 大東漢文學 Vol.42 No.-

본고는 15세기 前期 太宗朝 朝野 諸賢의 吉再 讚詠詩 작품을 중심으로 하여, 朝鮮朝 역대 제현의 吉再에 대한 讚詠詩 양상을 검토한 것이다. 太宗朝 조야 제현의 吉再 讚詠詩 창작은 경상도관찰사 南在의 주도 하에 이루어졌다. 즉 南在가 吉再의 臣節과 孝行을 칭송하는 讚詠詩 몇 수를 짓고, 權近 등을 비롯한 조야의 제현이 이에 화답하여 詩卷을 완성하게 된다. 현재 남아 있는 자료를 통해 살펴볼 때, 이 詩卷에는 南在, 權近을 위시한 30분가량의 작가들이 참여하여 총 53수의 讚詠詩를 남겨놓고 있다. 太宗朝에 이르러 南在, 權近 등이 앞장서고 조야 제현이 뒤를 이어 吉再 讚詠詩 창작에 나섰던 것은 일면 정치적 의도의 결과물로 볼 수 있다. 태종이 吉再에 대해 우호적 태도를 취하고 權近 등에 의해 吉再에 대한 국가 차원의 포상에 대한 필요성이 제기되면서도, 명분의 부족으로 인해 국가적 포상이 이루어지지 못하는 상황에서, 吉再에 대한 국가 차원의 포상을 이끌어 내기 위한 효과적 輿論 형성의 수단으로 吉再 讚詠詩 창작이 이루어졌던 것이다. This essay is to study on some panegyrical poems about Gil Jae created by men of distinction of many generations living in Joseon Dynasty era, focusing on some panegyrical poems about Gil Jae made by men of distinction both in and out of government in Taejong Era, the early 15th century. Some panegyrical poems about Gil Jae was written by men of distinction both in and out of government with the lead of Nam Jae, the governor of Gyeongsang Provinces in Taejong Era. In the process, Nam Jae made some works which eulogize the loyalty to his king and the filial piety towards his parents and then men of distinction both in and out of government including Kwon Geun finished the collection of poem following the creation of Nam Jae. Looking over the existing materials, I found that about 30 poets including Nam Jae and Kwon Geun participated in the creating the collection of poem and 53 panegyrical poems about Gil Jae remain today. It may be the result of political intention to men of distinction both in and out of government including Kwon Geun finished the collection of poem following the creation of Nam Jae. In that period, the king Taejong could not give Gil Jae the national accolade although the king had the amicable attitude toward Gil Jae and some people including Kwon Geun profound the need of national accolade. Some panegyrical poems about Gil Jae was created to make public opinion effectively with the intention to make Gil Jae national accolade.

야은(冶隱) 길재(吉再)에 대(對)한 력대(歷代) 찬영시(讚詠詩) 검토(檢討)(Ⅲ) -숙종(肅宗) 어제시(御製詩) 및 갱진(?進)·차운시(次韻詩) 중심(中心)으로-

남재철 ( Nam Jae-cheol ) 근역한문학회 2016 한문학논집(漢文學論集) Vol.45 No.-

본고는 15세기 전기 태종조 조야 제현의 야은 찬영시 및 15세기 후기에서 17세기 전기 사이 야은 유적지 방문 사림들의 야은 찬영시에 대한 검토에 이어, 국왕의 입장에서 야은의 충절이 크게 추숭되었던 17세기 말엽 이후의 야은 찬영시의 양상에 대해 검토한 것이다. 국왕의 주도 하에 이루어진 야은 찬영시 창작은 18세기 초기 숙종에 의해 시작되었다는 점을 밝히면서, 먼저 숙종 어제 야은 찬영시의 존재 양상과 그 의미에 대해 살펴보았다. 이어 숙종 어제시에 대한 당대 신하들의 갱진시 및 후대에 산출된 차운시의 양상에 대해서도 살펴보았다. 야은의 절의가, 야은 생전의 양촌의 기록 및 야은 사후 국가적 추숭의 결과물인 『삼강행실도』의 내용에서는 주로 백이·숙제와 같은 불사이군의 충절의 측면에서 강조되어 왔는데, 숙종의 어제시에서는 공명에 아무런 욕심이 없는 엄광과도 같은 은사의 청아한 풍도의 측면에서 강조되고 있다. 국왕의 입장에서 야은의 청아한 은사로서의 절의를 새롭게 부각시켜 칭송함으로써, 벼슬에서 밀려나 은거하고 있거나 은거할게 될지도 모르는 당대 사대부들의 삶에 대해서도 긍정적인 의미를 적극 부여해줌으로써 그들의 충성심을 고취시키고자 하였던 것으로 보인다. 숙종의 어제시에 대해 명곡과 동강은 갱진시를 통해서 자신들을 비롯한 당대 및 후대의 모든 사대부들이 태종·세종·숙종 등의 임금이 야은의 은사로서의 맑은 절의를 포상해준 사실을 듣고서 은사로서의 절의를 절로 흥기하게 될 것이라고 화답하고 있다. 후대에는 순조와 역천, 사미헌과 한주가 숙종 어제시에 차운시로 화답하였다. 숙종·순조, 명곡·동강은 야은의 은사로서의 측면에 주목하고 있는데, 역천·사미헌·한주는 야은의 백이·숙제에 비견되는 불사이군의 충신으로서의 측면에 다시 주목하고 있다. 숙종·순조, 명곡·동강은 국왕 또는 조정의 관료이지만, 역천·사미헌·한주는 재야의 학자라는 점이 이러한 차이를 가져온 것으로 추정이 된다. This essay is to study on some panegyrical poems about Yaeun Gil Jae created by other persons from the late 17th century when the loyalty of Yaeun Gil Jae was eulogized by the lead of a sovereign ruler. At first I examined the aspect and meaning of panegyrical poems made by King Sukjong in 1707, the early of 18th century. In the earlier records of Joseon Dynasty in the 15th century, the fidelity of Gil Jae was emphasized in the aspect of Baeki and Sukje, the loyal brothers of Chinese lore, refusing to serve two dynasties. On the other hands, in the panegyrical poems by King Sukjong, the integrity spirit of Gil Jae was emphasized in the aspect of elegant attitude of a recluse, Eomgwang who was a representative recluse in Chinese history and was disinterested in a successful career. And then I studied the aspect and meaning of panegyrical poems made by high-ranking official, Myeonggok Choe Seokjjeong and Donggang Cho Sangwoo who composed a verse in response to Sukjong`s poems following the rhymes of Sukjong in the same generation and the responding poetry which was created by King Sunjo, Yeokcheon Song Myeongheum, Samyhun Jang Bokchu and Hanju Lee Jinsang in the later generations. They pledged themselves to practice the integrity spirit of recluse influenced by the fact that some kings including Sukjong eulogized Yaeun Gil Jae.

Lee, Jae-Seo,Kang, Byung-Cheol 대한구강악안면방사선학회 2005 Imaging Science in Dentistry Vol.35 No.4

Purpose : To report the incidence of radiological findings from screening panoramic radiographs and verify the validity of the panoramic radiography for screening purposes. Materials and Methods : Six thousand one hundred and sixty panoramic radiographs taken from the patients visiting the Health Promotion Center of CNUH were selected for this retrospective study. Panoramic radiographs were examined into the following pathologic conditions : the presence of periodontal bone loss, dental caries, periapical radiolucencies, retained roots, impacted supernumerary teeth, impacted third molars, odontoma, cystic lesions other than radicular cyst, sialoliths, and mixed radiolucent-radiopaque lesions Number of pathologic conditions and Prevalence values were recorded. Results : The prevalences of pathologic conditions were 72.9% of periodontal bone loss, 32.2% of dental caries, 11.9% of periapical radiolucencies, 10.8% of retained roots, 0.4% of root fracture, 1.0% of impacted supernumerary teeth, 1.0% of impacted third molars, 0.06% of odontoma, 0.08% of cystic lesion other than radicular cyst, 0.2% of prolonged retention of deciduous tooth, 0.1% of sialolith, and 0.04% of mixed radiopaque and radiolucent lesion. Conclusion : Although the panoramic radiograph should not be used to replace intraoral radiographic and clinical examinations, this study showed that many dental pathologic conditions could be detected on panoramic radiographs. The panoramic radiograph might serve as a diagnostic aid in dental health evaluation programs.

Enhanced Maturation and Function of Dendritic Cells Using Hydrogel Coated Plate and Antigen Electroporation

Son, Cheol-Hun,Bae, Jae-Ho,Shin, Dong Yeok,Lee, Hong-Rae,Choi, Yung Hyun,Yang, Kwangmo,Park, You-Soo Informa Healthcare 2013 Immunological investigations Vol.42 No.4

<P>Dendritic cells (DCs) are potent antigen-presenting cells that can be matured <I>in vitro</I> from immature dendritic cells (iDCs) in the presence of several biological agents such as cytokine cocktail, CD40L, TNF-a and antigen loading, which are necessary and achieved using various protocols, such as lipofection, passive pulse or electroporation. However, these DCs maturation protocols may cause with a significant loss of cells because of cellular attachment and spreading during culturing. Some biomaterials that influence adhesion and development of cells have been used in cell culture techniques, and it was thought that they might be applied on the culture of DCs. In this study, we used polyHEMA, which is a hydrogel coating biomaterial that prevents DCs from adherence, and investigated whether hydrogel coating affects the maturation of iDCs. The efficiency in the generation of mDCs was improved through hydrogel coating procedure and a dendritic cell maturation marker, CD83, was significantly increased in hydrogel-coated culture condition. The antigen-loaded mDCs from electroporation were further expressed the CD83. The mDCs generated in the hydrogel-coated culture condition showed more, longer and thicker dendrites, and produced more amounts of cytokines such as IL-12 and IFN-γ. Therefore, it was suggested that the hydrogel-coated culture condition could improve function of mDCs.<fn><P>Cheol-Hun Son and Jae-Ho Bae contributed equally to this work.</P></fn></P>

황남철,최문석,이준혁,고광철,백승운,유병철,이종철,이광웅,조재원,박철근 대한간학회 2004 Clinical and Molecular Hepatology(대한간학회지) Vol.10 No.2

목적: 간의 국소 결정성 과형성은 일반적으로 특별한 치료가 필요 없는 양성 종양이다. 그러나 드물지만 합병증이 발생한 경우와 진단이 불확실한 경우에는 수술을 시행하게 된다. 이에 저자들은 간절제술을 시행한 국소 결절성 과형성의 임상적, 영상학적 특징들을 알아보고자 하였다. 대상과 방법: 1995년부터 2003년까지 수술을 시행하여 조직을 확인한 국소 결절성 과형성 환자 10명을 대상으로 연령, 성별, 실험실 검사 및 영상 소견과 조직 소견을 분석하였다. 결과: 연령의 중앙값은 37.5세, 남녀 비는 1.5:1이었다. 5예에서는 간세포선종이나 간세포암종을 감별할 수 없어서 수술을 시행하였으며, 수술 후 우연히 진단된 예는 4예이었다. 간세포암종의 위험 인자를 가지고 있었던 예는 4예(B형 간염 바이러스 보유자 3예, 간경변 2예)이었다. CT검사가 시행되었던 6예 중 5예는 동맥기에서 조영 증강을 보였고 문맥기 및 지연기로 감에 따라 주변과 동일(4예)한 또는 감소(2예)되는 양상을 보여 간세포암종과의 감별이 어려웠다. 크기는 3.2±2.2㎝이었으며 위치는 간우엽의 후하구역(S6)에 가장 많았다(30.0%). 4예에서 수술 전 침생검을 시행하였으나 고분화 간세포암종이나 간세포선종과의 감별이 어려웠다. 결론: 임상상, 영상검사 및 간침생검으로도 간세포암종이나 간세포선종과의 감별이 어려운 경우 수술을 시행하였으며 수술 전에는 발견하지 못하였지만 다른 질환으로 인한 수술시 우연히 발견된 경우도 있어 국소 결절성 과형성의 수술 전 진단이 어려운 경우가 적지 않음을 알 수 있었다. Background/Aims: Focal nodular hyperplasia (FNH) is a benign hepatic tumor with few serious complications and no malignant transformation. However, differential diagnosis between FNH and other liver tumors, especially hepatocellular carcinoma, is often difficult. Methods: Clinical features of surgically resected FNH were reviewed. From January, 1995 to February, 2003, 10 patients with surgically resected FNH were enrolled. Their age, sex, results of laboratory examination, imaging studies and pathologic findings were evaluated. Results: Median age was 37.5 years and sex ratio (male:female) was 1.5:1. In 5 cases, resection to exclude hepatic adenoma or HCC was performed. Four cases were diagnosed incidentally after surgery. Four patients had risk factors for HCC, such as hepatitis B virus infection, liver cirrhosis or both. The size of FNH was 3.2 2.2 cm. The most common site of the tumor was segment 6 (30.0%). Differential diagnosis with HCC was difficult in 5 of six cases in whom CT was performed. Although needle biopsies were performed preoperatively in 4 cases, it was difficult to distinguish FNH from hepatic adenoma or HCC. Conclusions: FNH was resected due to uncertainty of diagnosis, or incidentally during hepatectomy in patients with other liver disease. In the former, differential diagnosis with hepatic adenoma or HCC was a major problem despite extensive work-up including dynamic CT or biopsy. (Korean J Hepatol 2004;10:135-141)

수열합성 반응에 의한 3mol % 지르코니아 세라믹의 Fe2+, Fe3+, Er3+치환에 따른 상변태와 물성 변화

변지철, 이현철, 김택남, 류재경 배재대학교 공학연구소 2017 공학논문집 Vol.19 No.1

Zirconia is a heat-resistant material with a high melting temperature(2700℃) and has low thermal conductivity and excellent corrosion resistance. However, application has been limited due to brittleness, which is a disadvantage of ceramic materials. As a way to improve this, the addition of Y3+ improves the strength by phase transformation, which can improve the brittle problem, which is a disadvantage of ceramic. Many studies have been conducted on the addition of Y3+ after the addition has been found to be more efficient than the other additives. In this experiment, have studied the additives that replace this Y3+. Expeiments on the possibility of replacing Y3+ by adding an alternative additive considering Zr-sol(Fe2+, Fe3+, Er3+) in consideration of Atomic size, Crystal ionic raddi and Effective Ionic raddi. ZOC(ZrOCl2*8H2O) was dissolved in distilled water and synthesized by hydrothermal synthesis at 160℃ for 24hours. The formed Zr-sol was separated into a supernatant and precipitate. The supernatant was washed with distilled water, and the presence of chloride ion was confirmed using AgNO3. And add to the cleaned Zr-sol an additive that is believed to be a substitute for Y3+. The prepared Zirconia was calcined at 900℃ for 2hours, and the crystal phase was analyzed by XRD similar that of YSZ. The calcined powder was uniaxial pressed and sintered at 1500℃ for 2hours. The sintered specimens were first measured for specific gravity. And the particle size distribution, EDAX and FESEM were measured. 지르코니아는 고온에선 용융하는 (2700℃) 낮은 열전도율과 부식저항이 우수한 세라믹이다. 이에 우수한 파괴인성을 주기 위해 3 mol % Y를 첨가하게 되고, 상온에서 정방정 상으로 존재함으로써 파괴인성이 증가한 것으로 알려져 있다. 따라서 본 실험에서는 Y와 유효 원자 반경이 유사한 Er3+ (89pm)를 첨가함으로써, 과연 어떤 변화가 나타나는지를 알아보았다. 또한 원자가가 유사한 Fe3+와 Fe2+ 를 첨가하여 물성변화와 상변화를 조사하였다. 연구결과 이온 반경이 Y와 유사한 Er3+에서는 완전한 정방정상과 밀도, 투광율 (일부 파장은 제외)을 나타내었으나, 이온 반경이 약1/2 인 Fe2+, Fe3+를 첨가한 경우에는 단사정과 비정질 그리고, 650nm이하의 파장에서는 거의 투광하지 않는 현상을 보였다.

프랙탈 수학을 이용한 소자 표면의 구조 및 전기적 특성

조재철 초당대학교 초고속정보화센터 2001 초고속정보화센터논문집 Vol.2 No.-

전자소자의 전자현미경 사진을 프랙탈 이론을 적용하여 소자의 전기적 특성을 분석하였다. 전자소자 표면의 전자현미경 사진을 이진코드로 변환하여 그린인 형태를 프랙탈 차원으로 처리하였으며 보이드는 프랙탈 프로그램으로 처리하였다. 그래인 밀도와 전기적 특성은 프랙탈 차원에 의존하였다. ZnO 바리스터의 그래인 크기는 Sb2O3의 첨가량에 따라 감소하였으며 Sb2O3 의 첨가에 따라 스피넬 구조가 형성되었고 ZnO 그래인 형성을 억제하였다. Sb2O3첨가께 따른 ZnO의 그래인 크기는 5∼10μm이었다. 프랙탈 차원이 증가할수록 그래인 밀도는 복잡해지며 전기적 특성이 양호해졌다. The structural properties that SEM pholograph of electronic devices surface studied by fractal mathematics program were investigated to verify the relations of electrical characteristics. The SEM photograph of electronic devices surface was changed by binary code and the grain shape was analyzed by fractal dimension. The void of electronic devices surface was found by fractal program. The relation between grain density and electrical properties depend on fractal dimension. The grain size in ZnO varistors surface was decreased by increasing of Sb2O3 addition. the spinel structure was formed by Sb2O3 addition and it was depressed the ZnO grain formation. The grain size of ZnO by Sb2O3 addition were from 5 to 10[μm]. When the fractal dimension was high, the grain shape of electronic devices was complex and the electrical properties was improved.
