수술가이드를 이용한 무피판 임플란트 술식에서 임플란트 드릴링이 열발생에 미치는 효과

유지현,정승미,최병호,주상돈,Yoo, Je-Hyeon,Jeong, Seung-Mi,Choi, Byung-Ho,Joo, Sang-Don 대한치과보철학회 2013 대한치과보철학회지 Vol.51 No.1

연구 목적: 본 연구에서는 수술가이드를 이용한 무피판 임플란트 술식에서 임플란트 드릴링이 열발생에 미치는 효과를 측정하였으며 드릴링 방법에 따른 온도 차이를 측정하고자 하였다. 연구 재료 및 방법: 하악 양측 제 1 대구치와 제 2 대구치가 없는 실험 모델에서 피판을 거상하는 임플란트 수술(실험A군)과 수술가이드를 이용한 무피판 임플란트 수술(실험B군), 그리고 핸드피스의 상하 수직 움직임을 제한한 후 수술가이드를 이용하여 무피판 임플란트 수술(실험C군)을 각각 진행하여 온도 측정을 하였다. 임플란트 드릴링 시 온도 측정은 thermocouple과 열전식 온도 기록계(Yokogawa, Tokyo, Japan)를 이용하여 측정하였다. 온도 측정 위치는 최종 임플란트 드릴(직경 3.8 mm)의 경계부에서 0.5 mm 떨어진 곳에서 3 mm 깊이(설측)와 6 mm 깊이(협측)로 하였다. 측정된 온도 값을 이용하여 종속변수인 온도가 정규분포 하는지를 검정하기 위해 Kolmogorov-Smirnov test를 거쳐 확인한 후 세 수술 방법 간의 평균 온도 차이를 검정하기 위해 independent t-test로 분석하였다. 결과: 피판을 거상하고 드릴링을 한 수술군(실험A군)에서 평균 온도는 $27.2^{\circ}C$($SD{\pm}2.1^{\circ}C$)를 보였고 피판을 거상하지 않고 드릴링을 한 수술군(실험B군)에서 평균 $27.5^{\circ}C$($SD{\pm}2.3^{\circ}C$)를 나타냈다. 이들 두 수술 방법 간 온도비교에서는 통계학적으로 유의한 차이를 보이지 않았다. 수술가이드를 이용하여 무피판 수술 시 상하 수직 움직임(upand-down pumping motion)이 없이 드릴링을 시행한 수술군(실험C군)에서 평균온도는 $37.0^{\circ}C$($SD{\pm}3.4^{\circ}C$)을 보였다. 이를 상하 수직 움직임으로 드릴링을 한 무피판 임플란트 수술군(실험B군)과 비교 시 통계학적으로 유의한 온도 차이를 보였다. 결론: 수술가이드를 이용하여 무피판 임플란트 수술 시 핸드피스를 상하 수직 움직임으로 드릴링을 시행하면 피판을 거상하여 수술할 때와 온도차이가 발생하지 않으나, 상하 수직 움직임 없이 드릴링을 시행하면 드릴링 시 높은 온도 상승을 보인다. Purpose: The aim of this study was to evaluate the heat generation in bone in vitro during the guided flapless drilling procedure and the effect of drilling methods on the heat generation. Materials and methods: A model that has missing the first and second mandibular molars bilaterally was used. In group A, classical flap implant surgery was performed. In group B, flapless implant surgery using surgical guide was performed. In group C, flapless implant surgery using surgical guide without up-and-down pumping motion was performed. Temperature was measured with k-type thermocouple and a real-time digital thermometer. The thermocouples were placed at 0.5 mm away from the osteotomy area at the depths of 3 mm and 6 mm. The measured values were evaluated with independent t-test. Results: The mean temperature generated was $27.2^{\circ}C$ ($SD{\pm}2.1^{\circ}C$) and $27.5^{\circ}C$ ($SD{\pm}2.3^{\circ}C$) for groups A and B, respectively. These differences were not statistically significant. In group C, the mean temperature was $37.0^{\circ}C$ ($SD{\pm}3.4^{\circ}C$). There were statistically significant differences between groups B and C with respect to the mean temperature. Conclusion: These findings suggest that guided flapless drilling with up-and-down pumping motion may not significantly increase the bone temperature.

유지현 한국전기전자학회 2018 전기전자학회논문지 Vol.22 No.4

In this paper, we propose recurrent CNN(Convolutional Neural Networks) for detecting seizures among patients usingEEG signals. In the proposed method, data were mapped by image to preserve the spectral characteristics of the EEGsignal and the position of the electrode. After the spectral preprocessing, we input it into CNN and extracted the spatialand temporal features without wavelet transform. Results from the Children's Hospital of Boston Massachusetts Institute of Technology (CHB-MIT) dataset showed asensitivity of 90% and a false positive rate (FPR) of 0.85 per hour. 본 논문에서는 뇌파 신호를 이용하여 환자의 경련을 감지하는 순환 CNN (Convolutional Neural Networks)을 제안한다. 제안 된 방법은 뇌파 신호의 스펙트럼 특성과 전극의 위치를 보존하기 위해 영상으로 데이터를 매핑하여 처리하였다. 스펙트럼 전처리 과정을 거친 후 CNN에 입력하고 공간 및 시간 특성을 웨이블릿 변환(wavelet transform)없이 추출하여 발작을검출하였다. 여기에 사용된 보스턴 매사추세츠 공과 대학 (Boston Massachusetts Institute of Technology, CHB-MIT) 아동병원의 데이터셋 결과는 시간당 0.85의 민감도와 90 %의 위양성 비율 (FPR)을 보였다.

비판적 풍자정신의 현대적 계승과 김지하 담시의 시사적 위상

柳志賢 안성산업대학교 1998 論文集 Vol.30 No.-

The purpose of this study is to analyze that the satiric characters of Kim Ji-Ha's narrative poem are originated from the traditional literature. It is examed by comparing and analyzing the aspects of satire between Gamyunkuk and Kim Ji-Ha's poetry. Satire was one of the useful mode of expression in the Gamyunkuk. It was also useful method to criticize circuitously the existing authority or valuse system and to correct the social abuse. By using the traditional satiric technique in the modern poetry, Kim Ji-Ha took the social concern into literature and used it as the mode of indirect resistance. Through this technique, he made the expanded form of poetry-Damsi and created the new meaning of poetry which is containing the criticizing consciousness.

학습공동체 참여 활동에 따른 대학생의 학습전략, 협력적 자기효능감, 학업성취 수준의 차이

유지현 학습자중심교과교육학회 2016 학습자중심교과교육연구 Vol.16 No.9

본 연구의 목적은 학점이 부여되지 않는 비교과 교육과정으로 운영하는 학습공동체 프로그램에 참여한 학생들의 학습전략, 협력적 자기효능감, 학업성취 수준에 어떠한 차이가 있는지 확인하는 것이다. 이를 위하여 충남에 소재한 S대학 재학생 중 학습공동체 프로그램 참여 학생 76명을 실험집단, 미참여 학생 71명을 통제집단으로 설정하고, 학습전략, 협력적 자기효능감, 평점평균의 사전-사후 검사를 실시하였다. 효과성 검증을 위해 프로그램 실시 전후로 공분산분석, 대응표본 T-검증을 실시하였다. 연구결과 프로그램에 참여한 실험집단의 학습전략, 협력적 자기효능감 평균이 통제집단에 비해 유의하게 높은 것으로 나타났다. 또한 실험집단의 프로그램 참여직전학기 평점평균보다 해당학기 평점평균이 유의하게 높은 것으로 나타났다. 학습공동체 참여 학생들의 경우, 미참여 집단에 비해 서로 다양한 학습방법을 공유하고, 자신에게 더 효과적인 학습방법을 채택, 적용함으로써 학습전략에 대한 자기 모니터링의 기회가 더 많은 편이며, 적극적으로 팀 활동에 개입하고 자신의 역할을 잘 수행했다는 긍정적인 신념을 형성할 수 있다. 이러한 적극적 학습태도, 학습전략의 점검기회 등으로 프로그램의 도움과목 성적뿐 아니라 해당학기 평점평균이 향상되었다고 추론할 수 있다. 연구결과를 바탕으로 학습공동체 관련 후속연구에 대한 몇 가지 제언을 제시하였다.

'집'의 공간 시학과 1920-1930년대 시인들의 상실의식 고찰

유지현 안성산업대학교 1999 論文集 Vol.31 No.-

The purpose of this thesis, through the spacial character of the home, is to study the consciousness of poets in 1920-1930. Poets written in this thesis are Kim So-Wol(김소월), Baek Sok(백석), Lee Yong-Ak(이용악), Seo Jung-Joo(서정주), Yun Dong-Joo(윤동주). The poems of 1920-1930 frequently show the consciousness of loss for losing the base of life, it is actualized in the absence of the home or the loss of one's old home. By the analyzing poetics of space on the 'hone', we can exactly investigate the poetic consciousness of the those poets. They grope the new area by leaving the home actively, or exhibit the yearning for the past space. Also they indirectly express that the reason of the absence of the home are due to the colonial situation. Focusing on the poetics of space on the 'home', this thesis study the process of poetic speculation-loss and surmount.

Building energy consumption in Korea accounts for 20% of the total energy consumption, and this figure is on a continuous increase. About 71% of the buildings in Seoul are over 20 years old, indicating that the government should present a plan to activate remodeling for existing public buildings. Business facilities account for most of the public buildings managed by Seoul, and as a result of examining the distribution of the total floor area, it was found to be the most suitable for remodeling. Most of these business facilities are fire station facilities, and as fire station facilities consume energy 24 hours, great improvement can be expected when remodeling old buildings. Most of the energy consumption patterns of fire departments showed similar patterns in winter and summer. However, there was no significant difference in energy consumption between the fire stations in the 80s and the fire stations in the 00s. Therefore, Field measurements were carried out, and the reason why there was no difference in energy consumption was found through indoor environment and PMV results, indicating that the older the building, the colder it is in the winter. It is judged that the amount of energy used is limited according to the guidelines of the government and local governments, and through this, the indoor environment is maintained differently depending on the age while consuming a similar amount of energy. In addition, the improvement effect of remodeling was analyzed through the ECO2 program for buildings in the 1980s. It is expected to cost about 1.9 billion won to make the energy efficiency rating 1++, indicating the need to compare it with a dynamic simulation tool that can consider the behavior and patterns of occupants in the future.
