  • Remotely sensed data is the most fundamental data in acquiring the GIS informations, and may be analyzed to extract useful thematic information. Multi-spectral classification is one of the most often used methods of information extraction. The actual multi-spectral classification may be performed using either supervised or unsupervised approaches. This paper analyze the effect of assigning clever initial values to image classes on the performance of parallelepiped classification algorithm, which is one of the supervised classification algorithms. First, we investigate the effect on serial computing model, then expand it on MIMD(Multiple Instruction Multiple Data) parallel computing model. On serial computing model, the performance of the parallel pipe algorithm improved 2.4 times at most and, on MIMD parallel computing model the performance improved about 2.5 times as clever initial values are assigned to image class. Through computer simulation we find that initial values of image class greatly affect the performance of parallelepiped classification algorithms, and it can be improved greatly when classes on both serial computing model and MIMD parallel computation model.

  • Director Shin, Dong-il is one of the artists who is constantly pursuing his own work theme with his artistic insistence in the Korean film industry. He is an artist who criticizes modern society's systems, ideologies, and ills and questions them all the time. (2017), which he introduced in eight years after , is an extension of the work theme pursued by previous works, but it is a work that shows a different change from previous works. In this paper, I divide the world of works Shin, Dong-il pursues into three types of Others, Boundaries, and Drives, analyzing the common points and changes of . And through such analysis, I will examine the work theme of Director Shin Dong-il and measure the direction of change.

  • Relation extraction is an important information extraction technique that can be widely used in areas such as question-answering and knowledge population. Previous studies on relation extraction have been based on supervised machine learning models that need a large amount of training data manually annotated with relation categories. Recently, to reduce the manual annotation efforts for constructing training data, distant supervision methods have been proposed. However, these methods suffer from a drawback: it is difficult to use these methods for collecting negative training data that are necessary for resolving classification problems. To overcome this drawback, we propose a one-class classification model that can be trained without using negative data. The proposed model determines whether an input data item is included in an inner category by using a similarity measure based on lexical information and syntactic patterns in a vector space. In the experiments conducted in this study, the proposed model showed higher performance (an F1-score of 0.6509 and an accuracy of 0.6833) than a representative one-class classification model, one-class SVM(Support Vector Machine).

  • Perspective of director Bong Joon-ho shown in his movies up to now had been limited to domestic issues but that in the was shifted to the world, mankind, and future of humans. Images exhibited in his movies had the same meanings of many stories in the Bible and myths. The study looks into his philosophical world through the Christian view of the world and the Oriental circulation thinking; the story of the was expressed in before the glacial period, the 17 year glacial period spent in a train, and after the glacial period; structure of the story was composed of allegory as prior to Israelites' Escape from Egypt, desert life for 40 years, and entrance to Canaan. The end in the Bible does not mean complete collapse but it contains aspiration for new heaven and new earth to open a new era, to make a new promise with the God and to live a permanent life. This study intends to interpret the developed in a quite different meaning of imagination of humans' future from the previous one by the director Bong Joon-ho and to make another different explanation underlying in the image projected on the surface layer by the director.

  • The information on the land cover along stream corridor is important for stream restoration and maintenance activities. This study aims to review the different classification methods for mapping the status of stream corridors in Seom River using airborne RGB and CIR digital ortho imagery with a ground pixel resolution of 0.2m. The maximum likelihood classification, minimum distance classification, parallelepiped classification, mahalanobis distance classification algorithms were performed with regard to the improvement methods, the skewed data for training classifiers and filtering technique. From these results follows that, in aerial image classification, Maximum likelihood classification gave results the highest classification accuracy and the CIR image showed comparatively high precision.

  • If we look into genre movie, we can see that almost similar forms are repeated in a movie. Such similar elements are largely divided into three units from a mass of story to a very small camera angle. Those can be explained as Formula, Convention, and Iconography. Among those three, convention means custom and it is a structure or an incident in which one story can be divided into second one. Convention is an incident visualized in individual genre, and a movie director tunes audiences through the incident. The director leads a familiar story but all of a sudden, he transforms the familiar scene to a new story. As a product established from the beginning of movie history, movie convention helps communication between audiences and a director. Audiences familiarize themselves with movie convention through repeated activities of watching movies, and the director utilizes it to provide audiences with familiarity. Director Bong Joon-ho not only tunes audiences through traditional convention but also creates a new art work through transformation of convention. A study is conducted on how he used traditional convention and transformation to get a new idea and to engage in his work through his work .

Double Meaning Inherent in the Film : focused on the Movie "Perfume" (영화 속에 내재된 이중적 의미 : 영화 "향수"를 중심으로)

  • Double meaning inherent in the film is interpreted in the same context as it's called ambiguity in the literature. Ambiguity means that one word or one sentence can be interpreted in two or more meanings. In the movie, one behavior of a character, a prop or a costume with two or more meanings faces the audience. A famous French direct Francois Ozon said "The director has always made movie contrary to his/her latest movie." This means that the film should seek to reform and it's his philosophy about the movie. Actually, it's the film's basis that a movie breaks the taboo. The film has always challenged taboos and led the progressivism. Taboos of western films are more intense than our country's moral and ethical level. Their taboos are to deny the sacred and legitimacy of Christianity. Particularly, as many people talk about the film to deny the divinity of Jesus Christ, it's sufficient to elicit an argument pro and con. This study is to choose the movie "Perfume"of director Tom Tykwer as a text, examine the highly elaborate and strategical double meaning in the movie and analyze the western taboos to deceive the audience skillfully.
