In this research, the similarity search algorithms are provided for large video data streams. A video stream that consists of a number of frames can be expressed by a sequence in the multidimensional data space, by representing each frame with a multidimensional vector By analyzing various characteristics of the sequence, it is partitioned into multiple video segments and clusters which are represented by hyper-rectangles. Using the hyper-rectangles of video segments and clusters, similarity functions between two video streams are defined, and two similarity search algorithms are proposed based on the similarity functions algorithms by hyper-rectangles and by representative frames. The former is an algorithm that guarantees the correctness while the latter focuses on the efficiency with a slight sacrifice of the correctness Experiments on different types of video streams and synthetically generated stream data show the strength of our proposed algorithms.

We propose a new optimization framework for the reactive scheduling. The proposed rescheduling scheme is specially focused on how to generate rescheduling results when equipment failure occurs. The approach is based on a continuous-time problem representation that takes into account the schedule in progress, the updated information on the batches still to be processed, the present plant state, the deviations in plant parameters and the time data. To update the predictive scheduling, we used right shift rescheduling and total regeneration when equipment failure occurs. And, a practical solution to the rescheduling problem requires satisfaction of two often confliction measures: the efficiency measure that evaluates the satisfaction of a desired objective function value and the stability measure that evaluates the amount of change between the schedules before and after the disruption. In this paper, the efficiency is measured by the makespan of all jobs in the system. And, the stability is measured by the percentage change in makespan and the modified sequence deviation in the predictive scheduling and rescheduling.

RPC(Rational Polynomial Camera) models have become the replacement model of choice for a number of high resolution satellite imagery providers. RPCs(Rational Polynomial Coefficients) provide a compact accurate representation of the ground to image geometry, allowing users to perform full photogrammetric processing of satellite imagery including block adjustment, 3D feature extraction and orthorectification. This paper presents an algorithm for 3D feature extraction using downhill simpler method which requires only function evaluations, not derivatives. The algorithm was implemented as an executable software program and tested using stereo IKONOS images of Seoul city. The results showed that the proposed algorithm was fast and accurate enough to be used as a practical method for the 3D feature extraction from stereo images with RPCs.

Effective and efficient representation of color features of multiple video frames is an important vet challenging task for visual information management systems. This paper Proposes a Video Browsing Service(VBS) that provides both the video content retrieval and the video browsing by the real-time user interface on Web. For the scene segmentation and key frame extraction of video sequence, we proposes an efficient scene change detection method that combine the RGB color histogram with the X2 (Chi Square) histogram. Resulting key frames are linked by both physical and logical indexing. This system involves the video editing and retrieval function of a VCR's. Three elements that are the date, the need and the subject are used for video browsing. A Video Browsing Service is implemented with MySQL, PHP and JMF under Apache Web Server.

Although bytecode has many good features, it has slow execution speed and it is not an ideal representation for program analysis or optimization. For analysises and optimizations. bytecode must be translated to a Static Single Assignment Form(SSA Form) But when bytecode is translated a SSA Form it has lost type informations of son variables. For resolving these problem in this paper, we create extended control flow graph on bytecode. Also we convert the control flow graph to SSA Form for static analysis. Calculation about many informations such as dominator, immediate dominator. dominance frontier. ${\phi}$-Function. renaming are required to convert to SSA Form. To obtain appropriate type for generated SSA Form, we proceed the followings. First. we construct call graph and derivation graph of classes. And the we collect information associated with each node. After finding equivalence nodes and constructing Strongly Connected Component based on the collected informations. we assign type to each node.

The principal purpose of this study is to analyse and critique how precisely the representation of women in the film Retrato de Teresa reconstructs the socio-cultural image of the female in the late seventies of Cuban society. The film of Pastor Vega is obviously an outstanding challenge on the new subject of 'women's liberation' against machismo in the context of the Cuban society. Teresa, the female character, as a socio-cultural image of the Cuban society don't focuses on the declarative and iconic images of the women's role as a revolutionary heroin that had appeared frequently in the films of the sixties, but she struggles for getting more realistic and pragmatic values such as women's emancipation to take rights in daily life. Therefore, the declaration of the emancipation of Teresa against machismo of her husband $Ram{\acute{o}}n$ has the special and symbolic meanings of social role and function of the film in the process of Cuban cultural revolution. The film concentrates on inducing the audience to make new perspectives such as women and gender issues in the daily experience of Cuban society where the machista ideologies and practices characteristic of a patriarchal society. Conclusively the female image of this film does not represent a national heroin, but reflects the women's desire, hope, and dreams in the society. Teresa makes the audience think of representations of the true meanings of the revolution in daily life, the machista ideologies in the patriarchal society, and the women's role and fuction in the Cuban society.

The characters' voices in the movie, Rashomon mean the absence of memories created by self-consciousness in order to avoid the crisis. The varying statements of the characters and the three spaces: the space of Nakanimon (th e ruins), the representation space as polyphony (the forest), the egoistic space of truth (the guardian), show the social ills of doubtfulness and mistrust among the Japanese at that time due to the defeat from the war. This matches with the polyphony theory of Mr. Bakhtin, a Russian cultural critic. The key concept of polyphony theory is that the voices that do not accord each other are not harmonized but each voice builds their own world and participates in the novel without being influenced by the creator. This study's aim is to discuss two aspects; Bakhtin's polypony theory allows polyphony film s to function as cinematic composition and spatial characteristics of polyphony films in the movie, Rashomon.

This thesis focuses on the five functions of film music as proposed by American composer Aaron Copland, and the application of these functions in the modern film Cinema Paradiso featuring music by Italian composer Ennio Morricone. Morricone has shown the application of these techniques in Western films such as the 1960s film A Fistful of Dollars and the top-rated 1980s films The Mission and Cinema Paradiso. Through his work, he maximizes the effects of representation in each scene by using variations of the theme music to effectively apply the functional theory of film music. Cinema Paradiso, especially, pursued the consistency and diversity of film at the same time. And it emphasized the specific atmosphere, intending to provide continuity in the scenes during the progress of the film. This thesis provides an understanding of the variation technique in film music, and the functionality of film music from scene to scene, as used by Morricone, for students majoring in film music.

This study explores the success factors of post-investment management in content projects, which have recently seen increasing quantitative and qualitative status. The dependence on investment is huge in projects in the domestic content industry. As a result, unlike other industries, the content industry has a large role and contribution of investors in terms of project management. This study is conducted on 15 venture capitalists who have a key function in domestic content investment, and draws on their successful experience, what factors are successful in management(project management). To this end, 10 representative project management areas at the research and practice level are manipulated to suit content projects, and success factors by management area are derived in a qualitative manner for films and games with genre and industrial representation. For each area of management, a total of 38 success factors were derived, ranging from as little as three to as many as five. Given the theoretical and practical implications of research and the limitations of research, we present future research directions.

My essay aims at reading Ginsberg's "Howl" and "Kaddish" with the concept of 'shaman-prophet-poet' to illustrate the dynamic relationship between his poetics and radical politics. Throughout his widely-ranging career, Ginsberg represents himself as a poet-prophet and commands a typical rhetoric of revelation as a way of decentering Cold War orthodoxies. While well aware of the oppressive and pervasive power of the dominant post-war ideologies, he adopts 'madness' to oppose conventional political, social, and religious institutions; by way of entering into the madness of this world and actively engaging himself as a victim, he can finally heal both himself and the world. This dual function of poet characterizes his rhetoric of revelation, but it doesn't appeal to the mainstream of American critical ideology where the post-structural approach to language and subject gives a skeptical look at any account of active human agency and humanistic belief in the possibility of language. In "Howl" and "Kaddish," Ginsburg persuades the reader of the truth of his own vision through the convincing and realistic portraits of his contemporaries as well as his own mother and family. Different from his visionary predecessors such as Emerson and Whitman, Ginsberg knew the difficulty of a negotiation between history and divine vision, and attempted to imbricate his family, friends, and even the larger social and political units within his visionary experience in order to avoid naive idealism, escapism, or solipsism. Furthermore, he deconstructs the Logos of Western prophecy and replaces it with the groundless identity and the nontheistic epistemology of Buddhism, which, in turn, leads to emptying his powerful language of absolutist meaning and prevents his prophecy from becoming re-reified as divine essentialism. Ginsberg's idea of poet and poem revitalizes the skeptical view on language and literary representation of our contemporary critical community which is unwilling to engage the experimental scope of his radical prophecy.
