  • In recent years, as frequency and intensity of severe weather disasters such as flash flood have been increasing, providing accurate and prompt information to the public is very important and needs of user-friendly monitoring/warning system are growing. This paper introduces a method that re-produces radar observations as multimedia contents and applies reproduced data to mesh-up services. In addition, a accurate GIS matching technique to help to track the exact location going on serious atmospheric phenomena is presented. The proposed method create multimedia contents having structures such as two dimensional images, vector graphics or three dimensional volume data by re-producing various radar variables obtained from a weather radar. After then, the multimedia formatted weather radar data are matched with various detailed raster or vector GIS map platform. Results of simulation test with various scenarios indicate that the display system based on the proposed method can support for users to figure out easily and intuitively routes and degrees of risk of severe weather. We expect that this technique can also help for emergency manager to interpret radar observations properly and to forecast meteorological disasters more effectively.

  • The study proposes an exploratory analysis on the success of animation films in Korea industry. It identifies animation films that have been successful in the Korean film industry during 2004-2013 period and explores (1) how the number of screens allocated to the films have been changed; (2) what are the major factors that influence the success of the films; (3) what are the differences between Japan and the US animation in terms of plots and genres; and (4) how the characteristics of the US animations are related to the success of the US market, the global market, and Korean market. Analyses show that the number of screens allocated to the animation films has been consistently increased due to the vertical integration of Korean film industry; and the (FTA) period, months in year (summer and winter break months for middle and high school students), and the number of screens allocated to the films were the major factors influencing the financial success of animations. It also finds that specific characteristics embedded in its own cultural trait were shown in the plots and genres in the animations. Lastly the study also finds that specific set of characteristics extracted from IMDB site influence certain markets. Budgets and actor's power were found to influence the success in the US market while period (pre-FTA, FTA, post-FTA) only influence the success in Korean market. The study points out that the success of the US and Japan animations in Korean film industry are due to the historicity of animation cultures which are not found in Korean animation industry.

  • The study is aimed to recognize the meaning of foundation study through understanding history and flow of foundation study in Korea. The analysis period is from 1998 when there was first boom of venture foundation in Korea after IMF to 2013 September when the latest thesis was made, and the analysis intends total 382 dissertations the online. The analysis was conducted in the fields of foundation study, foundation support, foundation steps, founding company forms, founder's demographic features, and from the analysis, the following conclusion could be drawn out. First, the field actively carrying out foundation studies is the business management & economics field, but the foundation is dealt as an object of study across the all industries. It could be identified that of the all industries, especially IT industry, food service industry, and contents industry are the fields showing much interest about the foundation. Second, the field attracting most keen attention among the fields of foundation support was the field related with the founders. Third, the main problem relevant to foundation study was that the foundation was judged in comprehensive viewpoint, not being judged with strategies, in detail. Fourth, investing from the company's form aspect, it was found that during the starting period, the main foundation trend was the venture firm foundation, but recently the foundation-relevant attention is focused on the small business foundation and the most dominant founder type is the youth including college students, and the women's foundation is paid continual attention and senior foundation is being actively discussed. According to these analyzed results, future foundation studies should actively promote the general foundation studies, the specified foundation studies reflecting each industry's specialities, the fusion studies.

  • In this paper, we propose a pioneering concept of DPD(Disaster Prevention Design) to realize a securable society in the future. Features of danger in the future society are expected to be diverse, abrupt occurring, large scale, and complicated ways. Due to increment of dangers with their features of uncertainty, interactivity, complexity, and accumulation, human-oriented design concept naturally participates in activities to prevent our society against disasters effectively. We presented DPD is an essential design activity in order to cope with dangers expected in the future societies as well as realize securable environments. DPD is also an integrated design aids including preemptive protections, rapid preparing, recovery, and interactive cooperation. We also expect these activities of DPD is effective for generation of new values in the market, satisfaction of social needs, expansion of design industry, and a novel chance for development in the future society. Throughout this paper, we submit various aspects of DPD concepts including definition, classification, scope, necessity, strategy, influencing elements, process, and its principle. We expect these concepts will be the seed and/or basement of DPD research for the future works. For the direction of study for DPD in the future, we emphasize alarm system for preemptive protection rather than recovery strategy for the damage occurred. We also need to research about progressive prevention techniques and convergence with other areas of design. In order to transfer the concept of product design from facility-oriented mechanism to human-oriented one, we should develop new kinds of city basis facilities, public-sense design concepts referred to social weak-party, e-Learning content design preparing disasters, and virtual simulation design etc. On the other hand, we have to establish laws and regulations to force central and/or provincial governments to have these DPD strategies applying their regional properties. Modern design activities are expanding to UI(user interface) content design area overcoming the conventional design concept of product and/or service. In addition, designers are recognized as art directors or life stylists who will change the human life and create the social value. DPD can be divided into prevention design, preparedness design, response design, and recovery design. Five strategies for successful DPD are Precaution-oriented, Human-oriented, Sense-oriented, Legislation, and Environment Friendly Strategies.

  • Calculating of matching cost is an important for efficient stereo matching. To investigate the performance of matching process, the concepts of the existing methods are introduced. Also we analyze the performance and merits of them. The simplest matching costs assume constant intensities at matching image locations. We consider matching cost functions which can be distinguished between pixel-based and window-based approaches. The Pixel-based approach includes absolute differences (AD) and sampling-intensitive absolute differences (BT). The window-based approach includes the sum of the absolute differences, the sum of squared differences, the normalized cross-correlation, zero-mean normalized cross-correlation, census transform, and the absolute differences census transform (AD-Census). We evaluate matching cost functions in terms of accuracy and time complexity. In terms of the accuracy, AD-Census method shows the lowest matching error ratio (the best solution). The ZNCC method shows the lowest matching error ratio in non-occlusion and all evaluation part. But it performs high matching error ratio at the discontinuities evaluation part due to blurring effect in the boundary. The pixel-based AD method shows a low complexity in terms of time complexity.

  • Recently, school violence has come to the fore as a social phenomenon. "Comprehensive countermeasures for eradication of school violence" as a policy safety are created by Safety Administration bureau and Ministry of Education, Science and Technology under the chairmanship of the Office of Prime Minister on Feb,2012. This policy is supposed to be test-operated for a year from March, 2012. but voices of concern about effectiveness have been brought up by some critics greatly. So 172 teachers in high school in Seoul were surveyed in order to examine the effectiveness of "Comprehensive countermeasures for eradication of school violence" with a questionnaire composed of 5 point Likert-type. Among the fundamental measures, there were a total of 12 countermeasures about 'Practices for personality education' (with the exception of unrelated one question). 'Expanding opportunities of various art education and Supporting reading activities' of them ranked highest on average. Then, 'Reflecting results of special feature related to character develops to the Selection of Admission officers and Self-directed learning was the next. And among the three countermeasures about 'Reinforcement of roles of the family and society', 'Pan governmental conducting annual campaign related to broadcast, press, civic group to combat school violence was highest. Finally, among the 7 countermeasures about 'Countermeasure about harmful factors of games and internet addiction', 'Reinforcement of preventive discipline about game and internet addiction' was highest and 'Development and Promotion of various educational contents for preventive discipline about game and internet addiction' was the next.

  • South Korean broadcasting industry has been under a significant level of structural change since the permission of new general programming channels in the end of 2010. One of the most characteristic features of the change may be the exodus of core manpower from the in-house productions of major terrestrial broadcasters which have been maintaining their dominant power over broadcasting content market based on their systems of tight vertical integration. This paper sheds light on the presence of a purposeful 'mechanism design' that aims to the expansion of market logics in South Korean broadcasting sector by promoting commercial media conglomerates, and analyses how this external design has been actualized while being interlocked with various internal factors of the broadcasting industry. This paper shows that on the backdrop of the mechanism design, some of new media conglomerates has successfully provided various incentives in contrast with those disincentive of terrestrial broadcasters, which in turn, has facilitated the exodus of elite producers. This paper, however, raises a set of questions about whether this relocation process of creativity led by commercial media conglomerates would, in the long term, guarantee more opportunities and potentials for the producers, as promised. As part of conclusion, inherent problems of present mechanism design are highlighted.

  • They insist that there is no more new stuff in modern art to change every circumstance rapidly. According to this situation, they recreate the works which are made with the existed idea or materials, and also transform creative concept which cites the existing functions with modern meaning. Furthermore they can look into any data everywhere from their daily routine using the internet. And this must become one of the general forms which they imitate others' works which are referred or chosen in modern art. These social complextion is called a parody and pastich is technique of the Post Modernism which is the existence of past. Using the new construction, the parody and pastich which can accomplish some better value and bring other meanings makes original recreation with the concept of copying and repeating. It keeps changing and is shaping up to be different aspect so far. Every field has a little different term using its own expression but it keeps empathizing each other a same essential meaning. Although it is like universal mode of expression, It is fact that the public cannot distinguish what is creation, imitation, or piracy. This thesis shows the concept of it and files for terms which is using like that. At last it selects some artist who worked with parody and pastich analyses and compares them and their works.

  • The purpose of this study is to develop a model of the TOC (Table of Contents)-based research record system and to comparatively analyze its usability, in order to comprehensively and systematically manage and practically use the various research records generated from the entire process of research and development. For this purpose, the templates for technical recording and the components of each item were proposed to enable technical recording based on TOC, and structured contents were designed to organically connect between these TOC technical records and existing research records. Also, a database logical schema was developed to design a database, and a test collection was constructed on the basis of research records and TOC technical records. Finally, the model of research record system was constructed by designing TOC record search system and user interface including integrated search system. Based on this model, the usability assessment was performed by comparing the existing distributed general systems with the TOC-based research record system. As a result of the comparative analysis of these two systems, the TOC-based research record system showed generally higher utilization of research records than the general systems.

  • With the explosive growth of information about books, there is a growing number of customers who find it difficult to pick a book. Against the backdrop, the importance of a book recommendation system becomes greater, through which appropriate information about books could be offered then to encourage customers to buy a book in the end. However, existing recommendation systems based on the bibliographical information or user data reveal the reliability issue found in their recommendation results. This is why it is necessary to reflect semantic information extracted from the texts of a book's main body in a recommendation system. Accordingly, this paper suggests a method for extracting keywords from the main body of novels, as a preceding research, by using TF-IDF method as well as the text structure. To this end, the texts of 100 novels have been collected then to divide them into four structural elements of preface, dialogue, non-dialogue and closing. Then, the TF-IDF weight of each keyword has been calculated. The calculation results show that the extraction accuracy of keywords improves by 42.1% in performance when more weight is given to dialogue while including preface and closing instead of using just the main body.
