이재서,송재진,심우섭,김대우,이승신,이철희,민양기 대한비과학회 2003 Journal of rhinology Vol.10 No.1

Backround and Objectives:Mucocele of the paranasal sinuses could be developed as secondary to trauma, tumor orsurgical manipulation. This study was conducted to investigate clinical features of paranasal sinus mucocele followingendoscopic sinus surgery and to determine the effect of endoscopic wide marsupialization for the treatment of mucocele. Materials and Methods:Thirty-five patients with paranasal sinus mucocele who were diagnosed and surgically treated atSeoul National University Hospital from Nov. 1996 through Dec. 2002 were retrospectively analyzed by their medical recordsand radiological imaging. Results:The most common chief complaint of patients with mucocele were ocular symptomsincluding periorbital swelling, proptosis and headache. Previous sinus operation, especially endoscopic sinus surgery was themost common cause of mucocele, which developed at mean period of 50 months after surgery. Most commonly involvedsinuses were ethmoid and frontal sinuses. Thirty-three out of 35 patients underwent endoscopic wide marsupialization of themucocele cavity, and the other two patients were treated via external approaches. No recurrence was observed until mean followupof 33 months. Conclusion:One should suspect the possibility of mucocele recurrence if a patient complains of ocularsymptoms several years after endoscopic sinus surgery. Meticulous operation and postperative treatment, and regular followupare needed for patients who underwent endoscopic sinus surgery because of a possible development of mucocele as a latecomplication. Although transnasal endoscopic wide marsupialization for the treatment of mucocele showed safe and good results,long term follow-up data is needed to establish it as the gold standard for treatment of paranasal sinus mucocele.

『유마경』과 원불교사상

이재수(李在洙) 원광대학교 원불교사상연구원 2014 원불교사상과 종교문화 Vol.62 No.-

본 논의는 원불교가 새로운 실천불교운동이라는 이해에서 불교의 혁신과 대중화에 크게 기여했다는 평가에서 출발한다. 원불교는 불교와 불이적 관계에 있으면서도 종교적 정체성을 모범적으로 구현해왔다. 원불교의 사상의 근저를 『유마경』에 주목하여 규명하였다. 『유마경』은 대승불교 반야의 공사상을 천양하고, 대자비의 바탕에서 불이적(不二的)인 실천의 모습을 보여주었다. 『유마경』은 심오한 반야공관(般若空觀)에 기초한 불가사의한 해탈법문, 입불이(入不二)법문 등의 사상을 통해 이상적인 사회는 현실에서 출발됨을 제시하였다. 현실 속에서 이상적인 사회를 건설하기 위한 다양한 방법과 실천행을 분명히 밝혔다. 그래서 현실을 바로보고 이상을 꿈꾸는 선각자들이 주목한 경전이다. 『유마경』 안에는 바로 교단에 안주하지 않는 새로운 인간형이 살아 숨쉬고 있다. 이는 원불교의 지향과 닮아 있다. 특히 기성 교단에 대한 비판, 붓다의 십대제자에 대한 비판과 새로운 불교관의 천명과 새로운 패러다임의 제시는 원불교가 지향한 불교의 생활화 대중화를 넘어 불교의 시대정신 구현에 자산이 되었다고 본다. 유마의 침묵은 언어를 떠나 참다운 실천으로 보여주었으며, 소태산대종사는 이를 일원상으로 보여주고 실천에 옮긴 것이다. 아울러 그러한 정신은 ‘불법연구회’의 개혁적인 실천과 ‘사회개벽교무단’, ‘원불교 환경연대’ 등 교단의 사회 참여로 연결되고 있다. 유마가 설파한 실천을 불교혁신론을 통해서 구체적 실천의 구조임을 밝혔다. 소태산대종사의 혁신사상을 불교사상의 대중화, 수행의 혁신, 일원상 신앙으로 혁신 등 세 가지로 정리하였다. 본 논의를 통해 『유마경』과 원불교의 만남을 통해 같은 길에서 닮은 듯 다른 모습으로 조화롭게 이 시대 진정한 종교란 무엇이며, 무엇을 해야 하는지에 대한 고민을 함께하는 동반자로 대화의 길에 함께하며, 실천해 가는데 이바지하길 바란다. This study started with an assessment that Won Buddhism made a huge contribution to the reform and popularization of Buddhism as a new practice Buddhism movement. Won Buddhism has implemented its religious identity in an exemplary manner in a non-dual relation with Buddhism. The present study set out to investigate the ideological foundation of Won Buddhism based on Vimalak?rtinirde?a-s?tra. Vimalak?rtinirde?a-s?tra announced and spread the ??nya idea of Prajna-Paramita-Sutra in Mahayana Buddhism and exhibited non-dual practice based on grand mercy. Vimalak?rtinirde?a-s?tra proposed that an ideal society should begin in reality through the mysterious nirvana law based on the profound ??nya idea of Prajna-Paramita-Sutra and the non-dual law. It also clearly suggested a range of methods and practice acts to build an ideal society in reality. Those are the reasons why pioneers paid attention to the sutra, seeing through reality right and dreaming of an ideal. There is a new type of person that does not settle down in the current religious body living and breathing in Vimalak?rtinirde?a-s?tra, which resembles the orientation of Won Buddhism. The criticism of the old religious body and Buddha’s ten pupils, clarification of a new Buddhist viewpoint, and proposal of a new paradigm became the assets to implement the zeitgeist of Buddhism beyond the familiarization and popularization of Buddhism sought after by Won Buddhism. The silence of Vimalak?rti showed true practice beyond language, and Master Sotaesan showed it as Ilwonsang and translated it into practice. The spirit has been connected to the reformist practice of “Institute of Buddha-Dharma” and the social participation of “Social Beginning Administration” and “Environmental Alliance of Won Buddhism.” The present study found that the practice elucidated by Vimalak?rti had a structure of specific practice through the theory of Buddhism reform. The reform ideology of Master Sotaesan was arranged in three ideas, namely the popularization of Buddhist ideology, reform of asceticism, and reform into Ilwonsang faith. The present study will hopefully contribute to the conversation and practice for such questions as what true religion is and what one should do in the contemporary times based on the similar and yet different aspects in harmony on the same path through an encounter between Vimalak?rtinirde?a-s?tra and Won Buddhism.

이재서,강병철 대한영상치의학회 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 patientsvisiting 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.

이재서,강병철,윤숙자 대한구강악안면방사선학회 2005 Imaging Science in Dentistry Vol.35 No.2

Purpose : The purpose of this study was to investigate variability of doses with same exposure parameters and evaluate radiographic density according to the variability of doses. Materials and methods : Twenty-eight MAX-GLS (Shinhung Co, Seoul, Korea), twenty-one D-60-S (DongSeo Med, Seoul, Korea), and eleven REX-601 (Yoshida Dental MFG, Tokyo, Japan) dental x-ray machines were selected for this study. Surface doses were measured under selected combinations of tube voltage, tube current, exposure time, and constant distance 42 cm from the focal spot to the surface of the Multi-O-meter (Unfors Instruments, Billdal, Sweden). Radiographic densities were measured on the films at maximum, minimum and mean surface doses of each brand of x-ray units. Results : With MAX-GLS, the maximum surface doses were thirteen to fourteen times as much as the minimum surface doses. With D-60-S, the maximum surface doses were three to eight times as much as the minimum surface doses. With REX-601, the maximum surface doses were six to ten times as much as the minimum surface doses. The differences in radiographic densities among maximum, mean, and minimum doses were significant (p<0.01). Conclusion : The surface exposure doses of each x-ray machine at the same exposure parameters were different within the same manufacturer’s machines.

CPI 보안 강화 코드 변환의 실용적인 동등성 검사 기법

이재서,최태형,이규호,유재관,배경민 한국정보과학회 2019 정보과학회논문지 Vol.46 No.12

Code transformation is widely used to improve the performance and security of programs, but serious software errors can occur in this process if the generated program is not equivalent to the original program. There are a number of approaches for translation validation that can be used to prove the equivalence of programs, but the high cost of proof checking restricts the applicability of these techniques for large programs. In this paper, we propose a practical approach for checking the correctness of LLVM code transformation. We first prove the correctness of the transformation rules using automated theorem proving before compilation. We then perform a simple code analysis method—as opposed to directly proving the program equivalence— to check whether the transformations rules are correctly applied to the generated code. As the complexity of the proposed code analysis is linear, our technique can be effectively applied to large programs, unlike previous techniques. To prove the effectiveness of the proposed approach, we present a case study on LLVM code transformation for a code pointer integrity instrumentation. 코드 변환 시의 동등성이 만족되지 않을 경우 소프트웨어 오류를 야기할 수 있다. 기존의 정리 증명을 통한 코드 변환의 동등성 검사는 코드의 규모가 커질수록 기하급수적으로 높은 비용이 요구되기 때문에 실제 소프트웨어 개발 시에 적용하기 어렵다. 본 논문에서는 규칙 증명과 코드 검사의 분리를 통하여 실용적인 LLVM의 코드 변환의 동등성 검사 기법을 제안한다. 먼저 주어진 코드 변환 규칙의 동등성은 자동정리증명을 통하여 컴파일 전에 별도로 증명한다. 그리고 컴파일 과정에서 변환 전과 후의 코드에 대한 정적 분석을 수행하여 코드 변환 규칙이 생성된 코드에 올바르게 적용되었는지 검사한다. 이러한 코드 분석의 수행 시간은 코드의 규모에 선형으로 증가하기 때문에, 규모가 큰 코드에도 효과적으로 적용될 수 있다. 제안된 연구를 코드 포인터 무결성(code pointer integrity) 보안강화 코드변환에 적용하여 LLVM 기반 도구제작에 활용하였다.

Objective Evaluation of Surgically Corrected Velopharyngeal Insufficiency with Nasalance on Nasometer

이재서,정영호,성명훈,이철희,민양기 대한비과학회 2000 Journal of rhinology Vol.7 No.1

Background and Objectives:Various kinds of surgical correction have been performed for management of velopharyngealinsufficiency (VPI). This study was conducted to evaluate the efficacy of nasometer by comparing the speech evaluation withthe nasalance change in patients who had undergone surgical correction of VPI. Materials and Methods:Twelve cases of VPI,who had undergone surgical correction at Seoul National University Hospital between January 1996 and June 1999, were retrievedin this study. Nasality in all cases was evaluated by the speech evaluation and nasometer before and 3 months after the operation. Results:Postoperative nasalance decreased from 49.0% to 40.9%. Seven of nine patients with decreased nasalance after theoperation showed improved nasality by the speech evaluation. Three patients with increased nasalance or no change in nasalancedid not show change of nasality by the speech evaluation. Seven cases of improved nasality by the speech evaluation representedsignificant decrease in nasalance. Conclusion:The speech outcome after surgical correction of VPI may be evaluated objectivelywith the change of nasalance.
