최대 블록화 방법을 이용한 묵자획 특징 추출에 관한 연구

김의정,김태균,Kim, Ui-Jeong,Kim, Tae-Gyun 한국정보처리학회 1997 정보처리학회논문지 Vol.4 No.4

본 논문에서는 오프라인 한자의 특징 추출을 위한 최대 블록화 방법(Maximum Block Method:MBM)을 제안한다. 최대 블록화란 처며 찾아진 화소로부터 블록을 점차 키워 나 아가감 으로서 입력문자의 골격선과 특징점을 추출하는 방법이다.기존의 세선화 방법 에서는 국소적인 잡음의 영향과 굴곡점, 누락점 등에서 발생되는 왜곡 현상이 특징 추출 을 어렵게 하는 단점이 있었다. 본 논문에서는 최대 블록 생성으로 인하여 잡음블록의 제거와 합성으로 직선과 사선획을 찾으므로서, 정확한 특징점 추출하는 앙법임을 입증 하였다. 실험 데이타로는 프린터 결과물, 중고등학교 한자 교과서와 기타 문서 등을 사용하였다. 한자 이외에도 한글 및 영, 숫자를 입력하여 실험한 결과, 인식의 전처리 과정인 골격선 추출과 획의 특징 추출에서 매우 효과적인 방법임을 확인하였다. In this paper the Maximum Block Method is suggested for the Feature Extraction of stokes of off-line Chinese characters.The Maximum Block Method is a technique which enlarges the block from the first found pixel that wxtracts the skeleton and features of the input characters.The maximum Block mthod is an adequate technique for the correct extraction of the features since the exsting thining methods have shortcomings of making the feature extraction difficult from the distoritions generated from the effiects of the parial noises,inflection points and blemishes. The printed outputs and chinese books of the middle and high school students,and other materials are used for the test.It was found that the Maxthod is also an effective technique for the extraction of skeleton line and features,which is the preoprocessing of the pattern recognition,for the Korean chracters and English as well as chinese chracters.

림프절 전이를 동반한 췌소도세포종 1예의 세침흡인 생검소견

Islet cell neoplasms (ICNs) of pancreas are uncommon, and the cytologic features of ICN are not well delineated. We report a case of islet cell tumor with lymph node metastasis, describing the cytologic, histologic, and immunohistochemical findings. A 40-year-old woman was admitted due to upper gastrointestinal bleeding of 2 days' duration. Computed tomography of the abdomen showed a diffusely infiltrating bulky mass in the body and tail of the pancreas. The fine needle aspirate showed moderate to high cellularity, monotonous cell population, single ceil predominance over small cell clusters, and eccentrically located nuclei. Although the definite diagnosis of ICN on the cytologic basis is difficult, the cytomorphologic features are sufficiently distinctive to suggest the diagnosis.

李白 閑適시에 보이는 시간의 흐름에 대하여 - 〈春日醉起言志〉를 중심으로

金宜貞(Kim, Eui-Jeong) 중국어문학연구회 2021 중국어문학논집 Vol.- No.131

This paper focuses on the flow of time expressed in the LiBai(李白)’s poem 〈Chunriziqiyanzhi〉and studies the flow of time in literary works. What this paper is trying to deal with is not the author"s notion of time, but the flow of time revealed in the work. In order to solve this problem persuasively, this paper summarized the flow of research on time in Western scientific history and adopted the time theory of Husserl’s Phenomenology as the main position. Time in human consciousness is not a moment without length like a point. It has flow and depth in a series of past and future orientations, and is now expanded by conscious memory. This paper selected 19 works whose descriptive form is relatively similar to 〈Chunriziqiyanzi〉 in total 36 works belonging to “XianShi” and distinguish various aspects of time flow within them. The passage of time had some unconscious development, and other dimensions had areas of reflection that deliberately brought about past events. Under this framework, there were four types of analysis. They are compression and concentration(A) · leap and expansion(B) · intermittent expansion(C) · manipulated present(D). It revealed how the flow of time develops within each type, and how it connects to the delivery of the theme or the atmosphere of the entire works.

정상인에서 측정한 바이오피드백의 정신생리학적 특징

김율리,구문선,김의정,유범희,Kim, Youl-Li,Koo, Moon-Sun,Kim, Eui-Jung,Yu, Bum-Hee 대한수면의학회 2002 수면·정신생리 Vol.9 No.1

본 연구는 정상인을 대상으로 바이오피드백 시스템으로 측정된 정신생리적 반응의 특징을 파악하는 것을 목적으로 시행되었다. 연구 결과 20대에서 피부전도반응이 다른 연령대에 비해 유의하게 높았으며, 여성에서 전두부 근전도가 남성에 비해 유의하게 높았다. 한편 정상인에서 바이오피드백 측정치와 자가 평가한 기분 변수와는 관련이 없는 것으로 나타났다. 본 연구의 결과는 향후 바이오피드백 시스템 기기를 이용하여 평가를 할 때 성별, 연령별 특징을 고려해야 함을 시사한다. 본 연구에서 제시된 정신생리변수에 관한 중요한 특징들은 향후 동종의 바이오피드백 시스템을 이용한 연구결과를 비교하는 데 도움이 될 것으로 기대된다. Objectives: This study is aimed at measuring psychophysiological responses using a biofeedback system in healthy people to obtain basic normative data for biofeedback research and treatment. Methods: Ninety-six healthy volunteers (55 males and 41 females : average age $30.4{\pm}8.0$) without any history of major medical or psychiatric illnesses participated in this study. Psychophysiological responses were assessed using the ProComp+ and BioGraph program (ver. 2.1) with regard to forearm and frontal electromyography (EMG), electrodermal response (EDR), and skin temperature. They were measured in 3 phases (baseline, stress, and recovery phases), respectively. Beck depression inventory and Spielberger state and trait anxiety inventory were used to measure mood states. We compared psychophysiological responses according to age and gender differences, respectively and examined the relationship between mood states and psychophysiological measures. Results: People in their twenties showed higher EDR levels in the 3 phases than those of other age groups. Female subjects showed higher frontal EMG levels in the 3 phases compared with male subjects. There was no significant correlation between biofeedback measures and mood states in these subjects. Conclusion: We present normative data of psychophysiological responses measured by a biofeedback system in healthy people. These results suggest that gender and age should be considered as important variables in assessing psychophysiological responses using a biofeedback system.

Haar Cascade 필터링을 통한 마스크 착용 여부와 발열 체크

김의정(Eui-Jeong Kim),김인중(In-Jung Kim) 한국정보통신학회 2021 한국정보통신학회 종합학술대회 논문집 Vol.25 No.2

최근 2020년부터 본격적으로 유행한 코로나19를 예방하기 위해 발열 체크, 마스크 착용 유무를 확인하는 곳이 많아졌다. 그러나 마스크 착용과 발열 체크는 일반적으로 사람이 직접 측정하거나 한명씩 기계 앞에 서서 측정하는 방식이 대부분이며 일반적으로 발열 체크시 피부의 최고 온도를 측정하므로 정확도가 떨어지고 대량의 인원 측정시 병목이 나타날 수 있다. 따라서 본 연구에서는 마스크 미착용자와 발열자를 일반 카메라와 열화상 카메라, 인공지능 알고리즘을 통하여 실시간으로 정확하게 자동 분류하고 표시하여 전염병 확산을 막는 방법에 대하여 제안하고자 한다. Recently, in order to prevent the proliferation of COVID-19, which began in earnest in 2020, an increasing number of places have been measuring the temperature and required to wear a mask. However, as wearing a mask and checking the temperature are typically measured directly by a person or by a single individual positioned in front of the machine, standards may vary based on the person’s manual measurement method, wasting workforce. While standing in front of a device often measures the maximum temperature of the face, the standard of fever is also unclear. Both approaches can create bottleneck situations when checking large numbers of people. Furthermore, it is unable to conduct periodic measurements and tracking because the measuring machines are generally put only at the entrance. Thus, this study suggests a method for preventing the spread of infectious diseases by automatically identifying and displaying unmasked people and those with fever in real-time using a general camera, a thermal imaging camera, and an artificial intelligence algorithm.

크론병을 동반한 IgG4 관련 경화성 장간막염 1예

김의정 ( Eui Jung Kim ),김은영 ( Eun Young Kim ),송정은 ( Jung Eun Song ),이현철 ( Hyeon Chu Lee ),배규환 ( Gyu Hwan Bae ),오훈규 ( Hoon Kyu Oh ),이태성 ( Tae Sung Lee ) 대한소화기학회 2014 대한소화기학회지 Vol.63 No.3

Sclerosing mesenteritis (SM) is a rare disease characterized by chronic nonspecific mesenteric inflammation and fibrosis of unknown etiology. Some tumefactive SM shows diffuse accumulation of IgG4-positive plasma cells and is considered as a part of the spectrum of IgG4-related disease. An association between inflammatory bowel disease and IgG4-related disease has been indicated. A 45-year-old woman visited our hospital due to weight loss with intermittent lower abdominal discomfort. Pelvic ultrasound revealed a mass-like lesion in the abdominal wall and pelvis MRI demonstrated a 5.9 cm sized wall-enhancing mass with heterogeneous signal intensity from right adnexa to the abdominal wall. Tumor resection and adhesiolysis was done because of severe adhesion with the small bowel, colon, bladder, uterus, and abdominal wall. Appendectomy was also performed due to adhesion and edematous change. Histological examination of the resected mass showed findings that were compatible with IgG4-related SM. The resected appendix showed chronic granulomatous inflammation without evidence of tuberculosis. She was diagnosed with Crohn`s disease after undergoing colonoscopy and CT enterography. Herein, we report a rare case of IgG4-related SM that occurred in conjunction with Crohn`s disease.
