경계요소법을 이용한 위상변이 마스크의 단차 효과 분석

이동훈,김현준,이승걸,이종웅,Lee, Dong-Hoon,Kim, Hyun-Jun,Lee, Seung-Gol,Lee, Jong-Ung 대한전자공학회 1999 電子工學會論文誌, D Vol.d36 No.11

3차원 위상변이 마스크의 단차 효과를 분석하기 위해 투명 경계조건, 주기적인 경계조건, 및 연속조건을 가진 경계요소법을 광 리소그래피 공정 시뮬레이션에 새로이 적용하였으며, 해석적인 해와 참고문헌의 결과와 비교함으로써 구현된 모듈의 정확성을 검증하였다. 또한, 기존의 rigorous coupled wave analysis에 의한 방법에 비해 수렴성과 계산 시간 측면에서 경계요소법을 이용하는 것이 더 효율적임을 확인하였다. 끝으로 비교적 간단한 위상변이 마스크와 다층-위상변이 마스크에 대한 최적 설계 과정을 기술하였다. The boundary element method was newly implemented into an optical lithography simulator so that it could evaluate rigorously the topological effects of 2dimensional phase-shifting masks. Both transparent and periodic boundary conditions were applied for the method, and the continuity conditions were used for treating interface nodes. The accuracy of the module developed for simulating aerial images was verified by comparison with analytic solutions and published results. In addition, it was found that our simulator would be more efficient than the conventional method based on the rigorous coupled wave analysis in views of the convergence and the calculation speed. Finally, the optimal design of two phase-shifting masks was performed.

tRNA 염기배열 순서를 이용한 진화적 관계

이동훈,김영준,강현삼,이병재 한국유전학회 1986 Genes & Genomics Vol.8 No.2

The nucleotide sequences of tRNAs were compared and the homologies between a pair of sequences were calculated. The homology is high between phylogenically related organisms, but low between eukaryote and prokaryote. The organelle's tRNA sequence shows very lower homology with chromosomal tRNA sequence. The homology and evolotionary distance was obtained by the method of Kimura (1980) with the sequences of chromosomal tRNAs which have the same anticodon (GUC) to compare orthologous genes. The phylogenic tree was constructed by unweighted pairgroup method using arithmatic average (UPGMA). The time of divergence of prokaryote and eukaryote was estimated to be 6.4×10^(10) years ago and the branching order in this phylogenic tree was in good agreement with that obtained by primary protein structures and 5S rRNA sequences.

증례보고 : 내장동맥 동맥류 파열에 의한 자발성 혈액복막 1례

이동훈,김기범,장혜영,어은경,전영진,정구영 대한응급의학회 2003 대한응급의학회지 Vol.14 No.5

내장동맥의 동맥류는 임상적으로 매우 드물고진단 또한 어렵다. 대부분 초기의 임상증상은 복통을 호소하지만 동맥류에 특이적인 소견이 없어 파열에 의한 혈액복막이나 위장관출혈이 발생한 후 진단되는 경우가 많고 이에따라 사망률이 높다. 특히 본 예와 같이 중간잘룩창자동맥의 동맥류는 발생빈도가 매우 적고 다른 내장동맥 동맥류와비교해서 파열전 진단에 사용할 수 있는 방법이 혈관조영술로 매우 제한적이다. 하지만 응급실에 내원한 원인을 알 수없는 복통환자의 경우 발생빈도가 적지만 내장동맥 동맥류를 의심할 수 있어야 하고 만약 내장동맥 동맥류가 의심될경우에는 최근 사용이 증가한 역동적 컴퓨터 단층촬영과 혈관조영술 등의 적극적인 진단 방법을 사용하는 것이 필요할것으로 생각된다.

임산부의 심폐소생술 중 시행한 응급제왕절개술 1례

이동훈,김기범,어은경,전영진 대한응급의학회 2007 대한응급의학회지 Vol.18 No.1

Cardiac arrest during pregnancy is an uncommon event, occurring only about once in every 30,000 late pregnancies. Survival from such an event is exceptional. This case involves sudden cardiac arrest of a 32 weeks pregnant woman. The patient was found at unresponsive state and transferred to emergency center by EMS. At arrival, her EKG rhythm was asystole and we had no patient information. Upon initiation of ACLS, abdominal ultrasonography was done and we detected a fetal heart beat. Timely emergency caesarean section delivery was done and the 1- minute APGAR score of neonate is 0. After endotracheal intubation and respiratory assist, 3-minute APGAR score was recoverd to 3 and neonate was admitted to neonate ICU. The mother did not responsed to resuscitation efforts. Physiologic and anatomic changes occur during normal pregnancy, necessitating a modification of standard BLS and ACLS methods for successful resuscitation. When arrest does occur during the latter part of pregnancy, perimortem caesarean delivery may improve the outcome for both the fetus and the pregnant woman. 임신부의 심폐소생술에 있어서 빠른 기관삽관,산소 공급, 대동정맥 압박의 방지를 위한 위치 변화 등 임산부의 생리적 변화에 맞는 심폐소생술의 방법을 사용해야한다. 임신 20주 이후의 심정지의 경우 심정지 5분 이내의빠른 응급제왕절개술이 산모와 태아의 생존에 중요하며 임신주수, 심정지의 원인, 제왕절개술의 기술적 능력을 판단하여 시행여부를 판단해야 한다. 본 저자들은 흔하지 않은임신부의 심정지에서 심폐소생술 중 응급제왕절개술을 통한분만을 경험하였기에 보고하는 바이다.

The purpose of this study is to figure out the perceptions of correctional professionals about therestoration process of ex-offenders' family. A total of 11 professionals from various correctionalworks have participated in this study. The main questions are as follows: First, what is theimportant meaning of family restoration to ex-offenders? Second, what are the difficulties that existin the process of ex-offenders' family restoration? Third, what are the kinds of support needed forthe ex-offenders' family restoration process? These three questions have been organized as 10domains and 33 categories using consensual qualitative research(CQR). The results of this studyindicated the following outcomes. First, to ex-offenders, the meaning of family restoration processincluded a driving force for a new life, the different processes of family restoration based on thetypes of ex-offenders, and the reunion with family which was hard to endure during theimprisonment. Second, during the family restoration process, ex-offenders have experiencedhardships that were due to internal characteristics of individual ex-offenders, the disorganization offamily relationship, and social reentry. Third, the kinds of support required for the ex-offenders'family restoration process are the support for individuals' internal problems, rearing issues ofchildren, family relationship, and social reentry. The implications and limitations of this study havebeen discussed The purpose of this study is to figure out the perceptions of correctional professionals about therestoration process of ex-offenders' family.
