        허밍 질의 기반 음악 검색 시스템의 유사도 계산 알고리즘

        오동(Oh Dong Yeol),오해석(Oh Hae Seok) 한국컴퓨터정보학회 2006 韓國컴퓨터情報學會論文誌 Vol.11 No.4

        사람은 음악에서의 선율을 악보의 기보법과 같이 음표의 높이와 음표의 길이가 조합된 형태로서 기억하는 것이 아니라, 전반적인 음표 간의 높낮이의 흐름과 음표 사이의 상대적인 지속시간으로 구성된 음조 곡선 형태로 기억한다. 이와같은 선율의 기억 방식으로 인해 기존 음악 검색 시스템과 같이 건반을 이용한 주선율 입력이나 악보에 기보된 형태로 음악 검색의 질의를 이용하는 방법을 그대로 적용하기 어려운 점이 있다. 이에 본 논문에서는 사용자의 허밍을 질의로 사용하는 음악 검색 시스템에서의 고려 대상들과 기존에 연구된 허밍 질의 기반의 음악 검색 시스템을 살펴본다. 또한 사람이 선율을 기억하는 방식인 상대적인 음표 간 높낮이와 음표 지속 시간을 이용하여 음악 내에 특징 정보를 추출하고 이를 기반으로 허밍 질의와 단음과의 유사도 계산 알고리즘을 제안한다. 제안된 유사도 계산 알고리즘은 선율내의 음높이 차만 가지고 선율의 유사도를 비교하는 경우 발생할 수 있는 문제를 연속된 음간에 길이 차이를 이용하여 해결하였다. A user remembers a melody as not the combination of pitch and duration which is written in score but the contour which is composed of the relative pitch and duration. Because of the way of remembering a melody, the previous Music Information Retrieval Systems which uses keyboard playing or score as the main input melody are not easily acceptable in Query By Humming Systems. In this paper, we mention about the considerable checkpoints for Query By Humming System and previous researches. And we propose the feature extraction which is similar with the way of remembering a melody and similarity computation algorithms between melody in humming and melody in music. The proposed similarity computation algorithms solves the problem which can be happened when only uses the relative pitches by using relative durations.

        유비쿼터스 환경의 인증 및 권한 메커니즘 동향을 통한 분산 인증기법 방안 연구

        오동,성경상,김배현,오해석 한국융합보안학회 2008 융합보안 논문지 Vol.8 No.1

        사용자가 접하는 정보 시스템과 어플리케이션에 대한 관리가 중요한 문제로 대두되면서 시스템 접근과 관리를 위한 방법론이 제기되고 있다. 여러 가지 형태의 인증 기술이 사용되고 있지만, 복잡한 인증 관리 및 운용에 따른 비효율성은 유무선 환경의 다양하고 새로운 비즈니스의 성공적인 전개를 위해서는 부적절하다. 또한 서로 다른 인증 방식을 사용하는 모바일 컴퓨팅 환경 하에서 유연하고 연속적인 서비스를 기대하기란 매우 어렵다. 유비쿼터스 컴퓨팅 환경하에서는 상호운용성 및 보안성이 지원되는 분산 인증 방안을 연구개발하는 것은 매우 중요한 사안이다. 이에 따라 본 논문에서는 유선(fixed) 컴퓨팅 환경에서뿐만 아니라 이동(mobile) 컴퓨팅 환경까지 고려한 유비쿼터스 컴퓨팅 환경으로 확장 가능한 분산 인증의 관리 및 운용 방안에 대한 요구사항과 권한 메커니즘에 대해 살펴봄으로써, 향후 진정한 유비쿼터스 환경에서의 분산형 인증기법에 관한 적극적인 참여를 유도할 수 있을 것으로 기대한다. While an information system and administration for an application that a user contacts with raise a head by an important problem, a system approach and methodology for administration are mentioned. Authentication technology of various configuration is used, but non-efficiency by complicated authentication administration and operation inappropriate use are for a successful expansion of various and new business of wire/wireless environment. In addition, under the mobile computer environment with different authentic method each other, it is difficult at all to expect flexible and continuous service. Under the ubiquitous computing environment, It is very important thing plan to research and develop compatibility and the side of variance authentication plan that preservation characteristics are helped. Hereby, This paper look around an requirement items and authority mechanism for the administration and the operation mechanism of the distributed authentication considering expansion possibility of the ubiquitous computing environment not only fixed computing environment but also mobile computing. In future, we expect it by can guide participation about distributed authentication technique of the genuine ubiquitous environment.

      • 韓國農民의 生理的 年齡에 關한 硏究

        吳東烈 中央醫學社 1940 中央醫學 Vol.9 No.3

        852 middle class farmers, male and female, aged from 20 to 79, who inhabit in three different districts of Korea, were subjected to this experiment. This study was designed to verify the biological changes of human beings due to aging by measuring 18 kinds of physiological functions-physical structures and strengths, motor and sensory functions, cardio-pulmonary functions, basal metabolism, etc. Based upon 10 kinds of functions out of the 18 tested which have close relations with aging, such as, number of missing teeth, basal metabolism, frequency of tapping, grasping power, lifting power, expiratory force breath holding time, diastolic blood pressure, visual acuity for near and auditory function; the author reached the following conclusions by means of evaluating the scores in percentil of each group of the subjects. 1. As for the reduction due to aging in the scores of functional tests, audio-visual acuities were definitely low in those 30's and the rest of the functions except basal metabolism showed remarkable changes in those in their 40's. 2. In comparison with the average scores of the physiological functions of each corresponding age group, these scores decreased remarkably in those in their 40's and 60's in both sexes. 3. The average scores of physiological functions were higher in males under the age of fifty, and they were higher in females thereafter.

        흰쥐 C6 신경교종 세포에서 Venlafaxine 그리고 Dexamethasone 처리가 열충격 단백질 70의 발현에 미치는 영향

        유재학,이준석,양병환,최미란,채영규,김석현,노성원,오동,최인근,Yu, Jae-Hak,Lee, Jun-Seok,Yang, Byung-Hwan,Choi, Mi-Ran,Chai, Young-Gyu,Kim, Seok-Hyeon,Roh, Sung-Won,Oh, Dong-Yul,Choi, Ihn-Geun 대한생물정신의학회 2005 생물정신의학 Vol.12 No.2

        Object:The intracellular action of the antidepressant, venlafaxine, was studied in C6-gliomas using heat shock protein 70(HSP70) immunocytochemistry and HSP70 Western blots because HSP70 is associated with stress and depression. Methods:To examine how the glucocorticoid affects the expression of HSP70 in nerve cells, the rat C6 glioma cell was treated with dexamethasone for 6 hours. In addition, venlafaxine was administered to the experimental groups of C6 glioma cells for 1, 6, 24, and 72 hours each, after which the expression of HSP70 was investigated. Finally, venlafaxine and dexamethasone were simultaneously administered to the experimental groups for 1, 6, 24, and 72 hours, followed by an investigation of the expression of HSP70. Results:The short term(1 hour) venlafaxine treatment significantly increased the level of HSP70 expression. The short term treatment of venlafaxine with dexamethasone also increased the level of HSP70 expression but this reduction was not statistically significant. The long term(72 hours) venlafaxine with dexamethasone treatment significantly reduced the level of HSP70 expression. The long term treatment of venlafaxine also reduced the level of HSP70 expression but this reduction was not statistically significant. Dexamethasone(10uM, 6hours) did not affect the level of HSP70 expression compared with controls. Conclusion:Venlafaxine increases the expression of HSP70 at short term treatment, but prolonged treatment with dexamethasone suppresses the expression of HSP70.

        약물성 파킨슨 증후군, 지연성운동장애 및 정좌불능의 공존

        오동,이원익,김창현 大韓神經精神醫學會 1994 신경정신의학 Vol.33 No.6

        The authors studied about the prevalence of drug-induced parkinisonism(DIP), tardive dyskinesia(TD) and akathisia(AK) and also coexistence of them in 442 psychiatric inpatients at Seoul National Mental Hospital. We examined also several variables including age, sex, dosage of drug, duration of exposure to drug, duration of illness, whether they can be a risk factors to each of the side effect, DIP, TD and AK. The results of study were as follows : 1) The prevalence of abnormal movement disorder in 442 psychiatric inpatients was 43.7% and the prevalence of TD, DIP, AK, TD with DIP, EIP with AK, TD with AK and TD with DIP and AK was 14.2%, 7.5%, 2.4%, 3.9% and 0.6% respectively. 2) The prevalence of TD in the body was 40.4% in tongue, 18.2% in lower extremity, 15.7% in upper extremity, 9.6% in jaw, 7.6% in trunk, 4.5% in lip, 4.0% in face respectively. In DIP, the prevalence of each subscale was 30.3% in akathisia, 19.5% in salivation and 1.3% in walking difficulty. 3) The three variables, like age, duration of drug administration, duration of illness, can be risk factors to TD and TD with DIP group, but another four variables, sex, dose of antipsychotics, past ECT history and duration of total admission, were not. Conclusively, DIP, TD and AK coexisted in high rates, so we should be cautious about the treatment of coexisting case. Tardive dyskinesia and drug-induced parkinsonism have been hypothesized to reflect opposing states of dopamine function in striatum. In fact, long-term prospective study should be done to evaluate the correlation of dopamine activity and each side effect like TD, DIP and AK.
