In this paper, we present the method of detecting some face regions in video images using Support Vector Machine and Hidden Markov Model. Face images from a camera are mapped into a texture space and then, some texture informations are extracted in face images. Given texture informations, face regions are detected. For extracting some texture informations in face images, 10 Support Vector Machines are used. PCA(principle Component Analysis) is used to reduce dimension, and then a face pattern is obtained. The obtained pattern doesn't represent the entire image texture, but represent the pixel texture information. Accordingly the pattern represents a spacial distribution of each texture information. The detection of face regions is performed using HMM, which shows texture of input image and spatial characteristics of texture. In order to reduce the computational load to the human face detection, the presented method is based on the variation regions application. The method consists of two steps: moving region detection and face region detection. First, the moving region detection, the rough positions of moving objects in image sequence are determined using an adaptive thresholding method that automatically choose the threshold value for detecting the moving regions. Then, we obtained binary motion masks. Second, the face region detection, the pixels in the detected motion masks that have similar texture are extracted. Some candidate face regions are classified into real face regions using HMM. The experiment is showed that the presented method is robust to a motion-blur and saturated image under illumination variation.

Carl Orff의 Carmina Burana 분석연구

유수웅 경복대학 1998 京福論叢 Vol.2 No.-

본문에서 다루고자 하는 Carmina Burana는 전통적인 형식 및 화성구조에 악곡의 구조원리를 두지 않고 가사에서 파생된 리듬을 주로 하여, 단순한 화성구조 위에 주제를 집요하게 반복 사용하고, 복잡한 대위법을 인용하여 선명한 구조를 이루고 있어, 전체적으로 단순함과 리듬을 강하게 느끼게 하는 음향중심의 악곡으로 Carl Off의 음악적 특징들을 잘 나타내는 곡이다. 본 연구의 목적은 Orff의 대표적 작품인 Carmina Burana를 표현적인 방법을 통하여 20세기의 새로운 합창곡으로 Orff는 20세기 전반기를 지배한 주류-인상주의음악, 표현주의음악, 신고전주의음악 등에 얽매이지 않고 스스로의 의식을 고수하며 독창적인 방법을 만들어 가는 한편, 극음악을 통하여 원시성 극대화를 추구하였다. 기초성과 단순성을 가장 중심에 두는 그의 원시주의는, 엄격성과 인위적으로 조직된 복합성을 바탕으로 삼는 Stravinsky의 원시주의와는 또 다른 창의력을 보여주고 있기 때문이다. 그는 그의 동시대에 유행하던 낭만주의, 인상주의 등의 조류에 따르지 않고 원시적인 미를 느끼게 하는 기본적이고 직접적인 독자적 음악어법을 전개하였고, 무대음악 작곡에 전념한 독특한 작곡가였으며 리듬을 통한 새로운 음악 교육법을 주장한 음악교육자이며 또한 음악학자로서도 널리 알려져 있다. On this thesis, with a propose to study on Orff's characteristic, musical mode of expression, then his representative work, "Carmina Burana" has been analysed. In analysis those pieces, because Orff's music didn't follow traditions types of harmonious structures, but centered on sounds which characterize a repeat and simplicity stressed (emphasized) on rhythms derived from the song-text's moderation the characteristics of each element's musical structures and methods of combination, etc. were analyzed so mindly without adapting a tractional analytic method, taking regular section having the same elements (rhythm accompaniment-type, melody-composition, ect.) as "one-section" then Block-Section into several composing elements. His musical idea based on the unification of the three elements, music, language and action (specially dancing element). And as a drama performed by a resultant of those three, being called a "worldly shadow" (worldly drama:Welt Theater), a spread of drama as a "worldly shadow" became a basis for his creation of the stage-musics. He wa a characteristic composer who had developed a sole mode of expression of his own, without being tied with such as fashionable tendencies; Romantism, Impressionism, Expresionism, etc., which had dominated first over the first half or 20 century. He tried a Maximization of Primitivity, and his primitivism was on basis, simple and basical, which is entirely distinguishable with Stravinsky's primitivism strict, artificial and complex.

An efficient method to extract text regions in complex color images is proposed. An algorithm locates the spatial position and estimates the skew of the text lines which are present in image using the local color information and hough transform. The color image is divided into sub-blocks. Sub-blocks are classified into a background block and a character candidate block by intensity variance and contrast. The background intensity is erased from 3×3 neighbor blocks. Similar blocks in hue and saturation are grouped into a region. Regions are refined by several heuristic parameters such as color, size and position information. Binary image is obtained after region refinement and is segmented into connected components. Character candidate components are detected by filtering noncharacter-like components based on several heuristics. The skew of the text lines are estimated by applying the hough transform. The proposed method have been used to locate text regions in book cover images. Experimental results are reported.

The organizational costs which result from losing an employee are very high. Recently, Many researchers focused on not how people quit their jobs but why they don't leave them. Reflecting the idea of people's being "situated or connected in a social web, " embeddedness has several key aspects: the extent to which people have links to other people or activities, the extent to which their jobs and communities fit other aspects in their "life spaces," and the ease with which links could be broken-what they would give up if they left their present settings. As a result, one way to improve the embeddedness of travel agency in the organization is to form a unity among the employees through enforcement of consistent management policies, concern and consideration of each employee, activation of horizontal communication among the employees, and employees' participation in decision making and sharing employees' values.

This study was carried out to investigate the flora of Mts. Dae-am, Dae-woo, Baek-suk, and Sa-myung located on the east side of DMZ in province Yang-gu-gun, from July 1999 to August 2000. Although two hundred and fifty eight vascular plant taxa (70 families 167 genera) were recorded, this was only a part of representatives in this community because of the restrictin of collections within the military zone. The overall forest stand age of this area was 40 to 50 years, but occasionally ca 70 years old trees were found. We reported 11 taxa of the rare and endangered species proposed by the Ministry of Environment in this area. The Yong-neup, the only high altitude (alt. 1,200m) moore in south Korea, are located in the peak of Mt. Dae-am-san. Some species of this moore (Carex chordorrhiza Ehrh., Carex limosa L., and Gentiana jamesii Hemsl.) - were only found in south Korea. This moor would suffer vegetation change by natural moorland succession and human disturbances. The long-term monitoring of variation of annual vegetation, species distribution, numbers and distribution pattern of individuals of rare species are recommended for the wetland conservation.

전자음악 및 대중음악에 관한 비교문석 연구

인류 문명의 역사는 20세기에 이르러 이전의 그 어느 시기보다도 빠른 속도로 발전되었다. 이 가운데 대중문화의 발전은 각 문화의 독자적인 성장과 함께 여러 다양한 문화들의 상호 작용에 의하여 복합적인 형태를 형성하며 발전하게 된다. 이러한 대중문화의 한 부분인 대중음악 또한 대중문화의 유사한 모습의 발전양상을 띄게 되고 이것은 1950년대에 형성된 전자음악이라는 새로운 음악 경향을 흡수하게 되면서 보다 혁신적인 성장을 이루게 된다. 1960년대 말엽부터 형성되기 시작한 테크노음악은 전자음향기기의 발전과 많은 음악적 성장을 통하여 1990년대에 이르러서는 대중음악의 주류로서 자리하려는 움직임을 보이게 된다. 이 같은 테크노음악의 생성과 발전은 대중음악에 접목된 전자음악의 새로운 경향이라고 할 수 있으며 그 결과 다음과 같은 점을 발견 할 수 있었다. 첫째, 테크노음악은 전자음악의 대중화된 모습으로서 초기 전자음악의 실험적이고 전문적인 음악적 성향을 가지고 있으면서도 실제 대중들에게 소비되어지는 형태를 취하고 있다. 둘째, 테크노음악은 대중음악에 전자음악이 접목되는 가운데 생성된 형태로 그 과정에서 복합적인 음악의 성장을 이루게 되고 그 결과 세분화된 다양한 하위음악 장르를 형성하게 된다. 무엇보다도 테크노음악이 대중음악계에 미친 영향은 발전적인 새로운 음악 경향의 생성이라는 결론과 함께 테크노음악이 발전되면서 나타난 여러 가지 음악문화의 발전에 있다. 예를 들어 댄스 음악문화의 형성, 클럽문화의 정착화, 라이브 문화와 레코드 문화사이의 상호작용 등이 그것이라 할 수 있다. 또한 테크노음악의 미래지향적이고 도전적인 성격은 앞으로의 대중음악의 전망을 밝게 하고 있다. We have made so much rapid development in our human cultural history since 20th century than any other past, in this process, the development of mass culture has grown up and each culture has made unique process by mutual actions of various civilizations. Popular music as a part of mass culture has entered on similar shape with that and has made an innovating development by assimilation of new trend in music. Techno Music which has been building up through the end of 1960's intended to get the main position by development of electronic sound machinery and popular music. These formation and growth of Techno Music IS may be said as anew tendency of electronic music involved with popular music and as a result I could find several factors like these. In the first place, Techno Music has an experimental and special disposition of primary electronic music as a popularized form, but also can be used up by the real consumer. Secondly, Techno Music a kind of form which has sprung from the linkage of electronic music to popular music. In the process of correlation, complex music genre has grown and diverse, detailed subcategoried sort of music genre have arisen. More than anything else, the impact of Techno Music on popular music is the rise of new paradigmatic music pattern and the progress of various music culture triggered by the Techno Music development. We can easily see the influence in the formation of 'dance music' culture, the settlement of club culture, and the interplay of live performance culture with 'ever-prepared record-type products' culture.

본 연구는 중학생의 개인적특성에 따른 자아정체감을 살펴봄으로써 성장기의 자아정체감을 확립하는데 도움이 되는 기초자료를 제시하는데 그 목적이 있다. 본 연구의 연구대상은 2002년 현재 서울지역 중학교에 재학중인 학생으로 하였고, 층화표본추출법(Cluster random sampling)을 사용하여 서울을 강남과 강북으로 분류한 후 서울시 교육청에 등록된 학교에 난수표를 부여한 후, 각각 1개교씩 2개교를 선정하였다 선정된 학교에서 교사의 양해를 얻어 250명씩 총 500명을 표집하였다. 연구대상 500명 중 불성실하게 응답하거나 신뢰성이 떨어지는 53부를 제외한 447부가 본 연구의 분석자료로 사용되었다. 본 연구에서 사용한 측정도구는 설문지로 박아청(1996)이 제작한 한국형 자아정체성 검사 중 '정체감 유예'와 '정체감 혼미'를 제외한 '주체성', '자기수용성', '미래확신성', '목표지향성', '주도성', '친밀성'의 6개 영역을 각 8문항씩 총48문항으로 재구성한 류청렬(1999)의 검사지를 수정·보안하여 본 연구에 적합한 설문지를 완성하였다. 본 연구에서 자료분석을 위하여 사용된 분석방법은 SPSS 10.0 version 프로그램을 이용하여 신뢰도 분석(Reliab Analysis), T-검증(T-Test), 교차 분석(Crosstabs Analysis), 일원변량분석(one-way ANOVA) 및 요인 분석(factor Analysis)등의 통계기법을 사용하였다. 본 연구의 자료분석 결과와 논의를 통해 얻어진 결론은 다음과 같다. 개인적 특성의 변인으로 성별, 학년, 학업성적, 경제수준에 따라 자아정체감에서 성별은 '친밀성' 요인에 있어서는 여학생들이 남학생들보다 높게 나타났다. 학년은 '주도성', '목표지향성'. '자기수용성', '천밀성' 순으로 높게 나타났다. 학업성적은 학업성적이 높으면 전체 자아정체감이 높았으며, '친밀감', '자기수용성', '미래확신성', '주체성' 순서로 높게 나타났다. 경제수준은 '주체성'이 높게 나타났다. This study was intended to present the basic materials helpful for middle school students in their middle school days and establishing their self-identify in a period of growth. For this purpose, this study attempted to identify what effect middle school students' participation had on the formation of self-identity through the investigation of the relationship between their participation in self-identity. The questionnaire research was conducted for middle school students attending middle schools in Seoul as of 2002. For this purpose, 500 students were sampled using the duster random sampling method. 447 questionnaires returned from them were used as data for analysis of this study. Such statistical analysis techniques as reliability analysis, t-test, crosstabs analysis, one-way ANOVA and factor analysis were used to analyze data using the SFSS 10.0 version program. Based on the findings of this study, the following conclusion was drawn: First, an attempt was made to investigate self-identity according to such individual characteristic variables as sex, school year, school records and economic level. Middle school girls showed the higher level of intimacy than the schoolboys in terms of sex. Self-identity was shown to be higher in the ascending order of 'initiative', 'goal orientedness 'self-acceptance and 'intimacy' in terms of school year. Middle school students with better school records, showed the high overall self-identity, which was shown to be higher in the ascending order of 'intimacy', 'self-acceptance', 'future assurance', 'subjectivity'. They showed the high level of 'subjectivity' in terms of economic level.
