The card-based user interface is one of the easiest navigation methods for smart phones, and many of the contents have recently been exposed as cards. In this paper, we have dealt with the definitions of cards and the components of cards used in smart phones. The card can play multimedia including various images and media, and serves as an entry point into detailed contents through the arrangement of buttons or actions. The card UI had different characteristics depending on the type, if it could be classified into basic type, timeline type, workflow type, and dashboard type. The basic type and the timeline type were not suitable for the hierarchy and order of information, and they were suitable for providing large contents. The workflow type was not significantly different from the amount of content, horizontal content arrangement was possible, and the dashboard type was analyzed to be suitable for providing various data as graph or number.

In many applications, wireless sensor networks could be thought as data-centric networks, and the sensor nodes are densely distributed over a large sensor field. The sensor nodes are normally vulnerable in terms of security since they are very often deployed in a hostile environment and open space. In this paper, we propose a scheme for contents-based anomaly detection in wireless sensor networks. In this scheme we use the characteristics of sensor networks where several nodes surrounding an event point can simultaneously detect the phenomenon occurring and the contents detected from these sensors are limited to inside a certain range. The proposed scheme consists of several phases; training, testing and refining phases. Anomaly candidates detected by the distance-based anomaly detection scheme in the testing phase are sent to the refining phase. They are then compared in the sink node with previously collected data set to improve detection performance in the refining phase. Our simulation results suggest the effectiveness of the proposed scheme in this paper evidenced by the improvements of the detection rate and the false positive rate.

This study analyzed the use of scriptwriting and hologram technology for storytelling in the production of locally-centered cultural and artistic content. The musical <WolhwaJeon>, produced in the Gangneung area, was examined as a case study. The process of creating the script for the performance was used to establish the self-identity of the character "carp" and the stage visualization of the folktale "Yeonhwa." Furthermore, the use of hologram technology to actualize the inner expressions of the characters, deliver information, enhance spatiality, and visualize fantasy elements was examined. Through this approach, educational information about local folktales was provided to the local residents, and their pride in their region was heightened. This locally-centered content requires continuous development in a modern society that pursues cultural diversity, and future research is needed to produce and develop traditional and cultural content in other regions.

This study analyzed the most frequently used navigation cases in a desktop environment. As a result of the research, GNB induces users' search as the top element of the search structure and can place color, text, icon, and image elements. LNB could be classified in the form of a dropdown, flyout, dropline and mega menu. In this study, the navigation structure of Interpark and Interpark among open markets used by users was analyzed. G-Market's GNB has a two-tier structure with color, text, image, and icon elements, and Interpark has a three-tiered horizontal label. Interpark's GNB drew attention by placing a badge on the seasonal label, which is a temporary content section, unlike G-market. It can be seen that the LNBs of both shopping malls have flyout menus that protrude when you mouse over the category menu arranged in a vertical text form under the logo placed on the left. The flyout menu has a complex structure consisting of the layout of the mega menu. This study is meaningful in revealing user experience elements by analyzing the GNB and LNB of shopping malls these days where internet shopping is increasing.

Due to urbanization and industrialization, the importance of large-scale fire prevention, management and measures is increasing day by day. However, the fire site arrival rate in Golden Time, which is a factor that can minimize large-scale fire damage, of Pohang, a large city with a population of over 500,000, is relatively low. So additional fire fighting power deployment and infrastructure investment are required. However, as budget and manpower are limited, it is necessary to selectively deploy fire fighting power and invest in infrastructure. Therefore, this study attempted to present a fire damage rating that can compare the level of fire damage, which is an index that can help selectively provide fire fighting services in Pohang and make related decisions. For the index, the OD cost matrix was used to predict fire vulnerable areas with a high probability of increasing the fire scale in the event of a fire. Also fire damage was measured by predicting the level of fire damage in the event of a fire according to population, building density, and access of fire trucks. It is expected that the fire damage rating will be able to help in various decisions related to fire fighting service deployment and services not only in Pohang city, but also in other regions.

This paper is based on the perspective that the YTN Science, a science channel in Korea which plays a key role in the popularization of science, is suffering from low viewing ratings, insufficient content, and shortage of production. First, this study employs an exploratory method to identify current status of programming and operation of the Korean science channel along with its promotional strategy. Second, it aims to conduct an analysis on the science channels, specifically some major programs, of other nations including the U.S. (Discovery Channel, National Geographic Channel), United Kingdom (BBC Knowledge), Japan (Science Channel), and China (CCTV 10), seeking the possibility to apply and combine them afterward to the Korean TV channels specialized in science. A number of implications are derived from our diagnosis of present situation and analysis of abroad cases, and this helps us suggest the content development and promotional strategies as follows: First, due to the rising need for change in the programming strategy to enhance the value of the content, it is required to rearrange the programming in terms of the target audience and the viewer lifestyle, adopt a new strategy for building up the viewers' watching habit through 'stripping', and place strategic programs in prime-time. Second, as for the specific schemes of content production and application, it is recommended to establish a dual strategy in creating the content (one for conveying knowledge, the other for delivering fun), plan and use a representative character of the program, select scientific and technological topics with more Korean backgrounds, attempt strategic ties with SNS, deepen and diversify the material for programs, and implement a strategy to boost the OSMU. Finally, with regard to the promotional strategy, a constructive proposal may include raising channel awareness through science-related events and live broadcasting, performing promotional strategies by way of expanding to printed media like magazine and book publications, and intensifying online and mobile promotional strategy.

As an advance in medical technology development is being made, and people are increasingly aware of the importance of health, related investments and people's average life expectancy rise, which in turn leads to an increase in elderly people. Also, with a growing number of elderly people enjoying their leisure activities, the utilization of multimedia contents using computers is on the increase, leading to an activated research into the establishment of digital culture for the elderly people. This paper proposes a Korean text input system to enable the elderly to utilize digital contents. Text input interface has conventionally depended on keyboards. However, the keyboard wherein many keys are dispersed creates problems for the elderly, such as a protracted recognition of keys and a lowered concentration when they use the keyboard. To address these problems, in this paper, the grip type controller interface for console games was used and a corresponding alphabet location algorithm was developed. To verify these efforts, a simulator was developed to test 20 elderly people; as a result, their satisfaction over and convenience of using the grip type interface increased.

Recently, the Department has utilized the media facade as a means to attract new customers and promotional tools. In particular, we checked the rate of customer's gender who visited a large department store. The ratio of women's visit is 4.6 times more than men. This can confirm the need to produce a differentiated content of LED media facade by gender. This study are subject to an empirical analysis of differences of perception of evaluation factors of media facade in gender. At first we specified four factors which can evaluate the media facade according to gender by previous studies. There are aesthetics, artistry, comfort and harmony. And the hypothesis was set as "Each factor might be differences between the recognition of their gender" In order to verify a hypothesis the country's large department store was selected and experiment was performed. In the result of the experiment, among the four factors, aesthetics, creativity, and harmony were chosen, while comfort was dismissed. This results confirm that the following factors are needed to attract more women's customer at the department such as combination of space and media facade, combination of shape and color, appropriateness of the information and beautiful place, and directing way of content.
