목 적 : 본 연구에서는 두경부 암 환자의 방사선 치료 시 Neck node lower region까지 Target이 위치한 환자의 경우 기존의 상품화 된 두 가지 고정용구와 자체개발한 Shoulder Retractor의 유용성을 비교 평가하고자 한다. 대상 및 방법 : 본원에서 치료한 두경부암 환자 6명을 대상으로 사용한 고정용구의 종류에 따라 각각 2명씩 분류하여 좌, 우 Shoulder 위치변화와 Set up의 정확성을 OBI를 이용한 2D/2D 영상정합 위치보정 후 좌표 분석을 통해 비교하여 유용성을 확인해 보았다. 결 과 : 고정용구 종류에 따른 영상정합 위치보정 값(OBI A-P상 좌, 우 Shoulder 위치변화값)에 대한 평균값과 표준편차는 A그룹에서는 RT.Shoulder $1.07mm{\pm}3.99mm$, LT.Shoulder $-4.35mm{\pm}2.09mm$이고, B그룹에서는 RT.Shoulder $-0.37{\pm}5.91mm$, LT.Shoulder $1.26{\pm}5.28mm$, C그룹에서는 RT.Shoulder $-0.63{\pm}2.44mm$, LT.Shoulder $0.25mm{\pm}1.61mm$으로 나타났다. SET UP의 영상유도좌표 분석에서는 평균 및 표준편차 값이 A그룹에서 Vrt $-2.06{\pm}2.68mm$, Lat $-1.11{\pm}8.15mm$, Lng $0.34{\pm}3.78mm$, Rot $0.51{\pm}0.77^{\circ}$이고, B그룹에서 Vrt은 $-1.18{\pm}1.82mm$, Lat $-0.94{\pm}2.13mm$, Lng $-0.67{\pm}1.98mm$, Rot $0.91{\pm}1.04^{\circ}$이고, C그룹에서 Vrt은 $0.12{\pm}2.18mm$, Lat에서 $-0.79{\pm}1.62mm$, Lng에서 $-0.79{\pm}2.64mm$, Rot $0{\pm}0.49^{\circ}$으로 나타났다. 결 론 : 자체개발한 고정용구는 좌,우 Shoulder의 위치변화에 대한 재현성을 유지시킴에 있어 유용함을 알수있었고, 환자 변위요소(환자가 잡은 줄을 놓치는 현상과 발 끝의 위치와 모양에 따라 잡은줄이 한쪽으로 치우치는 현상)와 환자의 체중 변화로 인한 환자 자세의 고정문제를 줄임으로써 Set up의 오차를 줄이고 환자의 재현성을 유지시키는데 도움이 될 것으로 사료된다. Purpose : We compared the set-up accuracy and right-left Shoulder position variation of the manufactured device and other commercial shoulder-retractors in the head and neck radiation treatment. Materials and Methods : Six patients consist of three groups which were used three different Shoulder retractors. We measured position corrections of left and right Shoulder and the couch after the image guidance by using on board imager (OBI) for six head and neck patients who has the extended target to the neck node lower region. Results : The position variation correction of left (right) Shoulder after image guidance were $1.07{\pm}3.99mm$ ($-4.35{\pm}2.09mm$), $-0.37{\pm}5.91mm$ ($1.26{\pm}5.28mm$), $-0.63{\pm}2.44mm$ ($0.25{\pm}1.61mm$) for group A, B and C. The vertical, lateral, longitudinal position and angular corrections of the couch after image guidance were $-2.06{\pm}2.68$, $-1.11{\pm}8.15$, $0.34{\pm}3.78mm$, and $0.51{\pm}0.77$ degree for group A, $-1.18{\pm}1.82$, $-0.94{\pm}2.13$, $-0.67{\pm}1.98mm$, and $0.91{\pm}1.04$ degree for group B and $0.12{\pm}2.18$, $-0.79{\pm}2.64$, $0.79{\pm}2.64$, and $0.00{\pm}0.49$ degree for group C. Conclusion : In this preliminary study, we found the positioning accuracy of the manufactured Shoulder retractor is comparable to other commercial Shoulder retractors. We expect that the reproducibility and accuracy of the patient set-up could be improved by using the home made Shoulder retractor in the head and neck radiation treatment.

Objective : Surgery for the microvascular decompression is mostly concerned with injury to the cranial nerves or brain stem by cerebellar retraction. Intraopeartive brain stem auditory evoked potentials(BAEPs) has been continuously monitored on surgery to evaluate the extent of injury, recovery of the nerves and prognosis. Methods : Of the 161 cases of CP angle surgery from Feb. 1996 to Apr. 1998, 103 cases were monitored during operation. Thirty five patients who had undergone similar surgery were selected and evaluated ; 23 patients were monitored and 12 were not during surgery. If monitor showed more than 0.5 mSec delay of latency, surgeon was given a warning not to retract brain any more. If more than 1mSec delay, surgeon was informed to stop surgery and wait for the returning of evoked potentials. The level of amplitudes and delay of latencies during the initial stage of operation, opening the dura, insertion of teflon patches, and closing the dura and recovery were then compared. Resuls : Twenty patients were male and 15 were female. Their average age was 50.26 years. Mean amplitude during the initial stage of operation was $0.60{\pm}0.25mV$, at opening the dura $0.56{\pm}0.26$, after teflon patches insertion $0.49{\pm}0.20$, and after closure of dura $0.47{\pm}0.28mV$. Mean latency during the early stage of operation was $6.08{\pm}0.67mSec$, at opening of dura $6.38{\pm}0.55$, insertion of teflon $6.97{\pm}0.59$, and closing the dura $6.17{\pm}0.54$. There was statistical significance in the difference of amplitudes between each procedures, and in the difference of latencies. For the complete recovery of amplitude and latency, it usually took average 5.65 minutes(0-20 min). In monitored group, only one patient required more than 20 minutes to recover and suffered from hearing disturbance after surgery. Others were recovered within 10 minutes without complications. However, 4 out of 12 patients who were not monitored showed hearing disturbance, and 1 patient had temporary facial palsy and dizziness(p=0.000). Conclusion : The results indicate that continuous intraoperative monitoring of BAEPs during CP angle surgery is seen mandatory procedure to prevent operative complications.

Epidural steroid injection(ESI) has been a commonly applied conservative therapy for the management of chronic low back pain and sciatica. However, there are many reports concerning various local, systemic and neurological complications related to ESI. We report two cases with fatal complications after ESI for low back pain and sciatica. In both patients, ventriculitis and meningitis were causative factors to be fatal. Aseptic procedures and careful post-procedure assessment are essential to avoid serious complications following ESI.

Objectives : The purpose of this study is to report the effectiveness of Korean medical treatments on chronic glossitis using Yanggyeok-sangagam based on tutakbeop(透托法), and Ikgibohyeol-tanggagam based on botakbeop(補托法) and bobeop(補法). Methods : We treated a 83-year-old female patient who had glossitis by Korean medicine and acupuncture treatment. These treatments were performed from 2020.8.4. to 2021.3.4. We have confirmed the improvement of white plaque like a pseudomembranous pattern lesion and pain. We recorded images that include change of symptoms. Results : After the treatments were done, the scores of numeric rating scale(NRS), oral assessment guide(OAG) and oral health impact profile-14(OHIP-14) were decreased. The NRS score was decreased from 7 to 1. The OAG score was decreased from 20 to 9. The OHIP-14 score was decreased from 34 to 5. Conclusions : According to the result, Korean medical treatments such as Korean medicine and acupuncture treatment, followed by the cure rules- tutakbeop(透托法), botakbeop(補托法) and bobeop(補法) can be effective for the treatment of chronic glossitis.

본 논문에서는 컴퓨터 비전을 이용한 강의 도우미 시스템을 제안한다. 강의자가 강의를 진행하며 사용하는 강의 노트 및 관련동영상 등 다양한 강의 컨텐츠를 사용할 때, 컨텐츠 전환 등 컴퓨터 조작으로 인해 강의의 끊김이 유발된다. 제안하는 시스템에서는 강의 도중 강의 컴퓨터에 대한 조작이 필요할 때, 보드에 미리 정해진 기호를 그려 넣고 시스템이 이를 인식하여 해당 조작을 수행함으로써 강의 끊김 없이 손쉽게 강의를 이끌어 가도록 도와준다. 제안된 강의 도우미 시스템에서는 임의의 기호를 인식하기 위해 모양 문맥이라는 특징 표현자를 사용한다. In this paper, a teaching assistant system using computer vision is presented. Using the proposed system, lecturers can utilize various lecture contents such as lecture notes and related video clips easily and seamlessly. In order to do transition between different lecture contents and control multimedia contents, lecturers just draw pre-defined symbols on the board without pausing the class. In the proposed teaching assistant system, a feature descriptor, so called shape context, is used for recognizing the pre-defined symbols successfully.

온라인 필기인식을 위한 증가하는 데이터를 이용한 앙상블 기법

김태준(Tae-Jun Kim),장하영(Ha-Young Jang),박정완(Jeongwan Park),황성택(Seongtaek Hwang),장병탁(Byoung-Tak Zhang) 한국정보과학회 2014 정보과학회논문지 : 소프트웨어 및 응용 Vol.41 No.2

모바일 기기의 대중화와 함께 필기체 인식의 중요성은 더욱 커지고 있다. 필기 데이터는 데이터에 존재하는 분산(variance)이 매우 크기 때문에 데이터가 증가함에 따라 문제의 복잡도가 급격히 증가하는 특성이 있다. 이러한 특성으로 인하여 대용량의 데이터를 이용하여 인식기를 학습시키기도 어렵고 학습시간도 길어진다는 문제점이 있다. 본 논문에서는 이러한 문제점들을 해결하기 위한 앙상블 기법을 제시하였다. 제안한 방법론은 모바일 기기를 통해서 축적되는 필기 데이터를 효율적으로 이용하기 위하여 일정량의 데이터가 모일 때마다 새로운 약분류기(weak learner)를 추가함으로써 앙상블 모델을 구축한다. 필기체 인식을 위해서 많이 사용되는 인공신경망은 필기 데이터의 크기가 커짐에 따라서 데이터 내의 분산도 같이 커지는 문제로 인하여 학습 시간이 급격히 증가하게 되는데 앙상블 기법을 이용한 점진적 학습을 통해서 빠른 시간 안에 보다 효율적인 학습이 가능하게 된다. Today’s mobile devices offer more intuitive touch interfaces and support handwriting recognition. The within class variance of handwritten characters causes the growth of complexity in handwriting recognition as data grows. Because of it, more time and efforts are required to train the recognizer as data grows. We propose the ensemble method with batch incremental learning. The proposed method adds the new weak learner to ensemble model, when incremental data reaches certain amount. The ensemble method with batch incremental learning reduces the training time of artificial neural network with large data set. It also tends to cancel out overfitting problem caused by high variance.
