This study had two aims. First, the study intended to identify the influences of product benefits and product identification on consumers' purchase intention, Second, it wanted to assess the moderating effects of consumers' aesthetic seeking tendency on their decision-making process. Based on the stimulus-organism-response (S-O-R) paradigm and the product personality-brand identification-purchase intention model, this study proposed a research model, the benefits-product identification-purchase intention model. To test the model, a survey was conducted of female college students; a total of 298 questionnaires were analyzed. The stimulus used was a popular model of Nike running footwear: the Luna Eclipse+2. Factor analysis and structural equation analysis were conducted to analyze the research model. The results indicate : (1) The aesthetic benefit influenced product identification positively. The aesthetic benefit, functional benefit and product identification were all positively related to purchase intention. (2) The aesthetic seeking tendency mediated the influences of product benefits on consumers' purchase intention in the decision-making process. For consumers in the 'high' level group of aesthetic seeking tendency, aesthetic benefit and social benefit affected purchase intention and for consumers in the 'low' level group of aesthetic seeking tendency, the functional benefit only affected purchase intention. Based on this study, we find evidence that product benefits and aesthetic seeking tendency play important roles in consumers' decision-making process in product purchase.

As software grows more complex, it contains more bugs that are not recognized by developers. Attackers can then use exploitable bugs to penetrate systems or spread malicious code. As a representative method, attackers manipulated documents or multimedia files in order to make the software engage in unanticipated behavior. Recently, this method has gained frequent use in A.P.T. In this paper, an automatic analysis method to find software security bugs was proposed. This approach aimed at finding security bugs in the software which can arise from input data such as documents or multimedia. Through dynamic taint analysis, how input data propagation to vulnerable code occurred was tracked, and relevant instructions in relation to input data were found. Next, the relevant instructions were translated to a formula and vulnerable input data were found via the formula using an SMT solver. Using this approach, 6 vulnerable codes were found, and data were input to crash applications such as HWP and Gomplayer.

The purpose of this study is to develop conceptualization models of reading, information, ICT, and digital literacy through conceptual differences of these literacy by reviewing and defining the concepts of literacy as well as reading, information, ICT, and digital literacy. Computer literacy has emerged as a concept that explains the phenomenon of contemporary social, cultural, and information technology development, and since then, computer literacy has since changed to IT, ICT literacy, and digital literacy. As a result of the study, a conceptualization model of the reading, information, ICT, and digital literacy was developed. In this model, these literacy whose terms have changed according to the technological development of media, have been classified as medium-centered literacy. And reading and information literacy that focuses on the cognitive process of understanding, utilizing, and evaluating texts and information is categorized as process-oriented literacy. In the digital environment, reading and information literacy is a core competence to critically think and evaluate the texts that are on media, and further research is needed to reduce the reading and the information gap among readers.

Recently, public libraries as complex cultural spaces are becoming a trend, and public libraries as complex facilities that are built in one building or one site are being highlighted. This can be seen as part of a policy to expand public libraries as part of the government's Living SOC project. The establishment of libraries in government office is also included in this movement. Therefore, this study presented excellent cases by investigating the current state of government office in Korea and investigated citizens' perception on the establishment of public libraries in Busan Metropolitan City Hall. Based on this, a basic plan for the operation of public libraries in Busan Metropolitan City Hall, including basic directions, organization and manpower, collection development, and service programs (including specialization program), was proposed.

The purpose of this study is to define the concept of media information literacy and to develop educational content. To achieve the purpose of the study, literature analysis, interviews with field experts, and surveys with teacher librarians were conducted. The field experts recognized the media as a tool to use information and recognized information problem-solving skills, reading comprehension ability, media functions, case activities, and affective domain as the areas of media information literacy education. The teacher-librarians thought that information and media literacy which include its competency and educational content are more important than the digital literacy. As a result of the study, the concept of media information literacy was defined as knowledge, skills, and attitudes including the concepts of literacy, media literacy, information literacy, and digital literacy. In addition, educational contents of media information literacy were developed so that 'participation in democratic society', 'classification of media tools and contents', 'basic human rights', 'skills', 'digital tool manipulation' and 'information problem solving process' can be combined and applied in context.
