The purpose of this case study is to understand the characteristics and implication of videojournalist's image expression techniques in the television news programs, comparing with television camera reporter's image expression techniques. Texts chosen in this thesis are 120 programs of KBS2TV 'News Time' which had been on air from July to December in 2005. Shot size, camerawork, shot duration and camera angle of the images were analysed, which had been extracted through the processes of thematic classification. The results of the analysis of thematic classification shows us that videojournalist covered mainly social, economic and cultural news items, almost completely alienated in the fields of hard news as political and health-scientific news items which were very sensitive and influential on the life of the entire people of the nation. The results of the analysis on the characteristics of image expression reveals that videojournalist used one-shot more often than the camera reporter, showing us videojournalist's preference of close news gathering, and videojournalist used following and zooming much more often than camera reporter, showing us videojoumalist's preference of mobile and dynamic cameraworks, and videojournalist used low angles more often than camera reporter, also showing us videojoumalist's preference of candid camera style news gathering.

Application areas of Knowledge Discovery in Database(KDD) have been expanded to many R&D management processes including technology trends analysis, forecasting and evaluation etc. Established research field such as informetrics (or scientometrics) has utilized techniques or methods of KDD. Various systems have been developed to support works of analyzing large-scale R&D related databases such as patent DB or bibliographic DB by a few researchers or institutions. But extant systems have some problems for korean users to use. Their prices is not moderate, korean language processing is impossible, and user's demands not reflected. To solve these problems, Korea Institute of Science and Technology Information(KISTI) developed stand-alone type information analysis system named as KnowledgeMatrix. KnowledgeMatrix system offer various functions to analyze retrieved data set from databases. KnowledgeMatrix's main operation unit is composed of user-defined lists and matrix generation, cluster analysis, visualization, data pre-processing. Matrix generation unit help extract information items which will be analyzed, and calculate occurrence, co-occurrence, proximity of the items. Cluster analysis unit enable matrix data to be clustered by hierarchical or non-hierarchical clustering methods and present tree-type structure of clustered data. Visualization unit offer various methods such as chart, FDP, strategic diagram and PFNet. Data pre-processing unit consists of data import editor, string editor, thesaurus editor, grouping method, field-refining methods and sub-dataset generation methods. KnowledgeMatrix show better performances and offer more various functions than extant systems.

Humans have made a third person over a long history and differentiated them from each other. Discrimination of 'us' and 'them' has led Derrida to make works to look upon the human nature towards animal strangers. This study tries to examine upon the expansion of animal strangers by focusing on 'The Animal That Therefore I am.' Furthermore, the research asserts to pay more attention to animal strangers by looking at his works of how modern people think about animals in the current society. Derrida expresses his 'humiliation' that he felt when he faced his cat after a shower. This emotion brings up the topic that was neglected in the conventional wisdom and casts doubts on this. This emotion of humuliation is only felt by humans, and he explains this is one way of feeling like a 'human.' The researcher therefore focuses on the 'experiences of humans' and looks at the ambivalence of humans in culture and the irony in natural animals. This perspective criticizes Speciesism, which considers people other than oneself able to be suffered. This view also tried to escape anthro-pocentrism and looked at the animals on their own. This study examines current animal strangers with theories of Donna Haraway and Jane Goodal, and analyzes Derrida's artworks with Susan Sontag's philosophy. This aims to lead to a conclusion of how to reach an optimal relationship between human and animal. By focusing on Derrida, who has not been highlighted yet in this country, hopes to create effective communication between human and animal by explaining his artworks through new philosophy of animals.

The advent of Social Journalism coincided with the rise of social media to create and deliver news information; as a type of civic journalism, social journalism may be characterized as a new form of information gathering and news reporting which is fed by citizens creating news information through their use social networking services (SNSs). The current study analyzed a Facebook page called, to determine how this page was utilized during the onset of the citizen movement for the Egyptian democratic revolution to produce news, to facilitate interaction among the public and to deliver the news under the form of networked journalism. Each post uploaded onto the Facebook page from January 27 till February 2, 2011 was coded in its category, content and the contextual frame of the news. The results of the study showed that during the first week, straight news rather than those with opinions was produced most frequently. The research findings of the current study suggest that in a society of political turmoil, such as in Egypt and other Arabic countries, when the institutionalized media are controlled severely by the government or other forces, SNSs can perform journalistic media roles which create and distribute news information representing facts and reality, and simultaneously facilitate the public's interactions on social and political issues.

As whole genome sequences of many organisms have been revealed by small-scale genome projects, the intensive research on individual genes and their functions has been performed. However on-memory algorithms are inefficient to analysis of whole genome sequences, since the size of individual whole genome is from several million base pairs to hundreds billion base pairs. In order to effectively manipulate the huge sequence data, it is necessary to use the indexed data structure for external memory. In this paper, we introduce a workbench system for analysis and visualization of whole genome sequence using string B-tree that is suitable for analysis of huge data. This system consists of two parts : analysis query part and visualization part. Query system supports various transactions such as sequence search, k-occurrence, and k-mer analysis. Visualization system helps biological scientist to easily understand whole structure and specificity by many kinds of visualization such as whole genome sequence, annotation, CGR (Chaos Game Representation), k-mer, and RWP (Random Walk Plot). One can find the relations among organisms, predict the genes in a genome, and research on the function of junk DNA using our workbench.

In order to analyze textbooks from a discursive approach, the purpose of this study is to structuralize an analytic framework based on previous literature review and apply it to analyzing the meanings and their syntheses developed by words and visual mediators appeared in the definition of graph in first-year middle school textbooks. The discursive approach consists of the communicational approach developed by Sfard(2008) and the systemic functional linguistics developed by Halliday(1985/2004). In this study, ideational meta-functions for ideational meanings and interpersonal meta-functions for interpersonal meanings were employed to analyze the meanings produced by words and visual mediators in textbooks, whereas textual meta-functions for textual meanings were used for analyzing the synthesized relationships between words and visual mediators. Results show that first, density in mathematical discourse was very high and subjects in mathematical activities were ambiguous in the ideational meanings of words, and behavior aspect was more emphasized than thinking aspect in the interpersonal meanings of words which request student participations. In the case of ideational meanings of visual mediators, there was a lack of narrative diagrams, whereas there were qualitative differences in the case of offer. Second, there was a need for promoting a wide range of diverse synthetic relationships between words and visual mediators for developing enriched mathematical meanings through the varying uses like specification, explanation, similarity, and complement. These results are so important that they provide a new analytic framework from a discursive approach to textbook analysis because not only words, but also visual mediators are analyzed as tools for producing meanings in mathematics textbooks and their synthetic relationships are also examined.

Since an e-mail has been an important mean of communication and information sharing, there have been much effort to classify e-mails efficiently by their contents. An e-mail has various forms in length and style, and words used in an e-mail are usually irregular. In addition, the criteria of an e-mail classification are subjective. As a result, it is quite difficult for the conventional text classification technique to be adapted to an e-mail classification efficiently. An e-mail classification technique in a commercial e-mail program uses a simple text filtering technique in an e-mail client. In the previous studies on automatic classification of an e-mail, the Naive Bayesian technique based on the probability has been used to improve the classification accuracy, and most of them are on an e-mail in English. This paper proposes the personalized recommendation technique of an email in Korean using a data mining technique of frequent patterns. The proposed technique consists of two phases such as the pre-processing of e-mails in an e-mail folder and the generating a profile for the e-mail folder. The generated profile is used for an e-mail to be classified into the most appropriate e-mail folder by the subjective criteria. The e-mail classification system is also implemented, which adapts the proposed technique.

Recently, there is a strong interest in SW basic education for non-major students in universities, but SW non-majors are having a hard time learning. This paper proposes a class operation method that utilizes customized contents reflecting the interests of non-majors, rather than using existing learning contents for SW majors. The proposed method is to improve the education effects by increasing the learning motivation of SW non-majors. The paper shows a case study of A university, which has operated non-major SW basic education for more than five years. The case study analyzed the change of class satisfaction of students of pre- and post- learning group that reformed major-friendly contents about the same curriculum. As a result, the students of social sciences are interested in learning contents using public data that can examine the social and cultural phenomena of the country, and humanities students are interested in text contents such as novels, history books, and SNS articles. In addition to the understanding of the lectures, the class satisfaction was also greatly improved, and it showed that the major-friendly contents is useful for SW basic education of non-majors.

The purpose of this study is to review the established research practices and managerial methods on the range of Knowledge that have been independently studied from the conventional information system (libraries) and the managerial information system (MIS, DSS and EIS) within the quantitative and the non-quantitative perspective. The information systems were developed through their own purpose since the 1950s and these days the corporate environments have become integrated due to the rapid creation and expansion of information. Therefore, to make fast decisions in this situation it is appropriate that these two systems, Library and the managerial information system, should be dealt within the same category. In other words, not only the quantitative data that become main sources of DSS or EIS, but also the qualitative data such as the text documents, video and audio data, which have been managed in the libraries and information centers and not extracted from the former, can be used as the new knowledge source. Also BSS/EIS can provide the splendid infrastructure for Knowledge Management(KM) while libraries/information centers manage the comprehensive range of explicit and tacit knowledge, which can be a facilitator or main driver for KM.

The purpose of this study was to examine the social efficacy of children shown in reflective journal writing of early childhood education teachers focusing on picture book activities. The subjects were 47 3, 4 and 5 year old children in G Child Care Center in the Capital Area. Teachers were asked to do 20 picture book activities and to write a journal according to reflective thinking after each picture book activity. Through the reflective journals collected, this study attempted to interpret and analyze them qualitatively by classifying the journals and yielding text contents according to factors for children's social efficacy such as emotionality, emotion control, interpersonal relationship technique, and social knowledge understanding. From the results of this study, first, it was found that children expressed their emotion naturally and that they learned their unique emotionality while they lived together with their friends. Second, it was found that children perceived and controlled their own emotions by using their sympathy and empathy. Third, it was found that children recognized and accepted that they are different rather than the counterparts are wrong through their differences in each other's thoughts to compose the capability of interpersonal relationship. Fourth, it was found that children improved themselves by their understanding, respecting and accommodating their friends as members of society.
