Background and Objectives : Laryngeal cancer discrimination using voice signals is a non-invasive method that can carry out the examination rapidly and simply without giving discomfort to the patients. n appropriate analysis parameters and classifiers are developed, this method can be used effectively in various applications including telemedicine. This study examines voice analysis parameters used for laryngeal disease discrimination to help discriminate laryngeal diseases by voice signal analysis. The study also estimates the laryngeal cancer discrimination activity of the Gaussian mixture model (GMM) classifier based on the statistical modelling of voice analysis parameters. Materials and Methods : The Multi-dimensional voice program (MDVP) parameters, which have been widely used for the analysis of laryngeal cancer voice, sometimes fail to analyze the voice of a laryngeal cancer patient whose cycle is seriously damaged. Accordingly, it is necessary to develop a new method that enables an analysis of high reliability for the voice signals that cannot be analyzed by the MDVP. To conduct the experiments of laryngeal cancer discrimination, the authors used three types of voices collected at the Department of Otorhinorlaryngology, Pusan National University Hospital. 50 normal males voice data, 50 voices of males with benign laryngeal diseases and 105 voices of males laryngeal cancer. In addition, the experiment also included 11 voices data of males with laryngeal cancer that cannot be analyzed by the MDVP, Only monosyllabic vowel /a/ was used as voice data. Since there were only 11 voices of laryngeal cancer patients that cannot be analyzed by the MDVP, those voices were used only for discrimination. This study examined the linear predictive cepstral coefficients (LPCC) and the met-frequency cepstral coefficients (MFCC) that are the two major cepstrum analysis methods in the area of acoustic recognition. Results : The results showed that this met frequency scaling process was effective in acoustic recognition but not useful for laryngeal cancer discrimination. Accordingly, the linear frequency cepstral coefficients (LFCC) that excluded the met frequency scaling from the MFCC was introduced. The LFCC showed more excellent discrimination activity rather than the MFCC in predictability of laryngeal cancer. Conclusion : In conclusion, the parameters applied in this study could discriminate accurately even the terminal laryngeal cancer whose periodicity is disturbed. Also it is thought that future studies on various classification algorithms and parameters representing pathophysiology of vocal cords will make it possible to discriminate benign laryngeal diseases as well, in addition to laryngeal cancer.

Multilocular Squamous Odontogenic Tumor of Right Maxilla: A Case Report and Literature Review
이원범,김욱규,박혜련,유미현,정연화,황재준,황대석 대한구강악안면병리학회 2019 대한구강악안면병리학회지 Vol.43 No.4
Squamous odontogenic tumor (SOT) is a relatively rare, benign, small (rarely > 1.5 cm in diameter), but locally infiltrative and occasionally aggressive odontogenic epithelial lesion that appears to have harmatomous and neoplastic characteristics [1]. SOT is often asymptomatic, although it can present with mildly painful gingival swelling or tooth mobility. Radiographically, SOT is usually visualized as an irregularly or triangularly shaped unilocular radiolucency associated with the lateral roots of teeth. We report a case of the squamous odontogenic tumor occurring in a 60-year-old female in the right posterior maxilla with unusual radiographic and clinical appearances.

전자회절 Kikuchi Pattern의 전산모사와 그 응용
이원범,박찬로,박찬경,천창환,Lee, Won-Beom,Park, Chan-Rho,Park, Chan-Gyung,Chun, Chang-Hwan 한국현미경학회 1994 Applied microscopy Vol.24 No.4
A computer program has been developed to analyze easily the Kikuchi pattern which is useful in obtaining the crystallographic data of materials. This program can simulate the Kikuchi patterns for 14 Bravais lattice by using the matrix algebra. Convenient menu system was also added to enhance the applications of the program. That is, by varying the tilting angle, camera length (RADIUS) and $S_{max}$ in the menu, various Kikuchi patterns can be obtained. The simulated patterns, then, can be compared with the experimentally-obtained Kikuchi pattern to examine validity of simulation.

한국과 일본이 공동 주최한 2002 월드컵과 이를 계기로 한 한일 국민교류의 해는, 21세기 새로운 한일관계를 생각함에 있어서 시사하는 바가 적지 않다. 상호협력과 친선교류라는 측면에서 2002년은, 매우 성공적인 성과를 거둔 해였으며 금후의 양국 우호 관계에 새로운 희망을 가지게 하였다. 따라서, 우리는 이러한 한일 간의 새로운 흐름을 정착시키고 우호와 신뢰를 바탕으로 한 새로운 한일관계를 구축하는 전기(轉機)로 삼아야 하겠다. 본 발표에서는, 한일 양국의 우호 친선 관계에 있어서 2002 월드컵과 한일 국민교류의 해가 가지는 의미를 살펴보고, 금후 한일 우호협력 관계의 지속적이고 안정적인 발전을 위하여 우리에게 남겨진 과제가 무엇인가에 대하여 고찰하여 보고자 한다.

근대 한일관계와 개항지 부산 -신흥종교의 포교활동을 중심으로 -
이원범 경희대학교(국제캠퍼스) 국제지역연구원 2011 아태연구 Vol.18 No.3
본고의 목적은 근대 한일관계에서 개항지 부산에서의 일본거류민 사회의 형성과 자생종교의 역할에 대해 분석하는 것이다. 개항기 부산의 일본 거류민 사회의 형성은 일본인 종교 활동과 관계가 깊다. 역사적으로 19세기 천리교(天理教), 금광교(金光教)와 같은 일본의 자생종교는 일본인의 해외 이주가 시작되면서 해외 포교활동을 시작하게 되었다. 일본 자생종교의 해외 진출은 일본인 이민사회 성립을 전제로 일본인을 대상으로 하는 포교활동이 중심이었고, 이후 점차 이민사회를 넘어 현지인에게 확산되어 현지의 조직 기반을 확립하게 되었다. 일본정부의 지지를 받지 못했지만, 자생종교의 활동은 민중의 정신세계에 대한 지배를 강압적으로 추진하였던 일본 제국주의의 식민지 지배체제 속에서 지배계층과는 다른, 그들 자신의 전통적 가치의식과 행동양식을 고수하고 보편주의적 신앙운동으로 승화시켜 갔다는 것은 결코 간과할 수 없는 역사적 의미를 가지고 있다고 할 수 있다. Japan-Korea cultural exchange and cooperation was developed in many areas. In particular, Pusan played role of cultural gate from continent to Kyushu Island. In spite of Japan-Korea cultural exchange, there is lack of research under life of Japanese residents by that time. Aim of this essay is research under modern Japan-Korea relations regarding to opening of Pusan port and to investigate and analyze formation of Japanese residents community and its strong connection with religious activity. In 19th century Tenri and Konkokyo sects, indigenous Japanese sect, was brought by Japanese immigrants to Korea and propagated. Immigration of indigenous sects is reason why Japanese immigrants’ community was established, teaching activities was in great concern of Japanese people. Through teaching, knowledge was gradually spreading among Koreans and it was basis to establish some organizations. Even thought those indigenous sects activity was not supported by Japanese government, in the colonial system of Japanese imperialism rule, control of peoples spiritual life was promoted. To protect Koreans traditional values consciousness and style of life, different from ruling class, forced sublimation to universal belief movement cannot be overlooked, and it has historical meaning. In fact, from modern Japan-Korea cultural exchange ethnical conflict of dominating vs. dominated can be assumed, but it was not time of mutual exclusion nationalism. Co-existence and cooperation of people oriented to universalism can be recalled.
