This research will mainly focus on security issues in a university campus and delve into the risk factors and its characteristics due to the extreme polarization growth, and ultimately conduct research on legislative issues regarding safety & security management. A university campus is a miniature of the society, concentrated with human resources, material resources and knowledge information resources. It is also a region in which various underlying risk factors threaten these resources. However, due to the insensibility of danger and carefree indolence, these risk factors have been ignoring, leaving university campus amidst a "dead zone." Currently, a systematic and synthetic measures not only for safety inside the laboratory but also for the new type of crimes such as cyber crimes and motiveless crime due to extreme polarization, stress, uneasiness about the future, increase of mental illnesses, and drug abuse are urgently required. Therefore, I would like to introduce a legislative program in a crisis management perspective that can prevent universities from danger and protect the resources which would ultimately create a new security system.

This study was conducted with the focus on the process of constructing 3 definition and produced definitions as well as gifted students' conceptions of a mathematical definition In the study, the students made five types of regular polyhedrons (section1), observed them and stated their characteristics (section2) and then constructed a definition of regular polyhedrons based on their observations (section3). We divided students into two groups by analyzing students' definitions. One group made definitions that were consist with a mathematical definition of regular polyhedrons, the other one made definitions that were not. We checked if they fulfilled requirements for a mathematical definition. Researchers sought to gain various suggestions through the analysis of the observations and definition laid down by the students and through the characteristics shown by the students in the process of defining the concept.

This study was started to study the artistic aesthetic value of the antique artwork which is gradually declining in the field of metal crafts. The aesthetic interpretation of the lines and faces that have been identified through previous researches has been defined as a vitality and repetitive beauty. The researchers here have tried to express the formative works which can be repeated and change. As a result, it was found that the object of inquiry which can express the aesthetic beauty felt in the simple change of the line and the face is possible without the advanced technique of the difficult technique or the molding method through the natural and gradual change of the line and the face rather than the regular repetition. Through this study, it was found that the use of future lines and surfaces could be utilized as a variety of aesthetic expression methods as molding elements.

If the stage of establishing concept in interaction design approaches only analytic and numeral & quantitative aspects, it would be lack of new and creative ideas of concept for the suitable and proper relationship among the human and tools or machinery which is required in interaction design. This study has explored the possibility of access through the research of diverse point of views in the various knowledge systems about the relationship. That is this study has expanded from improvement-intended approach as analyzing human and tools and solving problems with analytic and engineering aspect to value-intended approach as pursuing new ideas though various points of relationship. Or so, to examine 'Relationship' in other knowledge systems, it could be the basic research for more deepening and specific study in interaction design. To integrate this study, at first, it deals with interaction design and process. Through the specific method, it has investigated the current interaction design and related studies. In the next, it has researched the study of relationship in oriental and western philosophy, cultural science, social science, natural science and engineering so it has examined the relationship in the various points of knowledge systems. Based on the contents, it has considered the possibility of access in interaction design to explain the relationship in the various points of knowledge systems.

It is obvious that the characteristics of the media are related with the visual expression found in film and video shots. It can be assumed that there would be unavoidable distortion when the space and objects are being framed into an image by the camera and that unavoidable distortion can be utilized for creative expression. Therefore the relationship among the shape of filming zone, the structure of the image, and the strategies of disposition of camera, actors, and objects were studied in accordance with expressional attempts found in film and video images. The classified cases of the expressions found in film and video was studied from the view of the dispositions and movements of the physical elements such as camera, actors, and objects which made the designated expression possible. Finally the organization of method to arrange of the elements used for film within film zone was resulted as the expressional directing methods for filming. Later the usefulness of the method was tested by the application of the method in educational procedure and the evaluation of the analysis of the students' results.

The 1972 United Nations Conference on the Human Environment sparked off actions aimed at protecting the ocean on all scales. Physical science was essentially in the foreground, and the ecological dimension remained in the background as well. During the following two decades, ocean uses increased and spread unexpectedly, and there was an urgent need for management patterns to deal with coastal areas, regional seas, and with the ocean as a whole. Meanwhile, mainly thanks to the Man and the Biosphere (MAB) programme, the ecological dimension of the environmental issue became more evident, while the concept of sustainable development was designed by the World Commission on Environment and Development (1987). As far as the ocean is concerned, by adopting Agenda 21, the 1992 Conference on Environment and Development (UNCED) could neither embrace a wholly ecology-oriented policy, nor adopt the concept of sustainable development in its whole extent. This circumstance encourages efforts to consider the ocean from an effective ecological perspective, and to explore how cultural and ecological systems have interacted. Hence the concept of diversity becomes an increasingly key factor.

Elementary mathematics textbooks present contents for enhancing problem solving competency. Still, teachers find teaching problem solving to be challenging. To understand the supports textbooks are suggesting, this study examined tasks from the challenging/thinking and inquiry mathematics. We analyzed 288 mathematical activities based on an analytic framework from the 2015 revised mathematics curriculum. Then, we employed latent class analysis to classify 83 mathematical tasks as a new approach to categorize tasks. As a result, execution of the problem solving process was emphasized across grade levels but understanding of problems was varied by grade levels. In addition, higher grade levels had more opportunities to be engaged in collaborative problem solving and problem posing. We identified three task profiles: 'execution focus', 'collaborative-solution focus', 'multifaceted-solution focus'. In Grade 3, about 80% of tasks were categorized as the execution profile. The multifaceted-solution was about 40% in the thinking/challenging mathematics and the execution profile was about 70% in Inquiry mathematics. The implications for developing mathematics textbooks and designing mathematical tasks are discussed.

In the age of global competition, city brand is a significant element for establishing a city's competitiveness. City branding is the process of building a storytelling about cities' content. Among the various contents that differentiate cities, this study seeks to discuss the role of an event and a city brand in the process of city branding based on the city marketing and event tourism literatures. This research uses grounded theory and a case study to examine Seoul exploring the changes in the Hi Seoul Festival and the Hi Seoul city brand over the last two decades. The qualitative research includes a secondary data analysis based on case studies from domestic and foreign regions and their festivals. The analytical results indicted three limitations: inconsistency, a lack of identity, and political leverage. Based on the limitations, this study discusses the importance of the connection between city identity and event content, suggesting implications for moving forward toward a stable Seoul city branding strategy for the Seoul Metropolitan Government.
