It is a story through which people share their ideas and express their thoughts. Storytelling is temporally and spatially interconnected narration that consists of characters, background, its beginning and its conclusion. Furthermore, the story in storytelling is a means of delivering culture and history; thanks to the development of various media, delivering and exchanging the story are conducted in a variety of forms. Due to the technological advancement, the way storytelling is done has changed, which was a method called digital storytelling. This storytelling has been frequently used in education; that is, teachers utilize stories to communicate their thoughts. As receivers, students understand a shade of meaning and the role of language, thus reorganizing the important factors in the context of meaningful events. However, in practice the classes are so teacher-centered that the role of students are relegated to that of passive learners, thus debilitating the interaction between participants; as a result, this situation shows serious limitations in that it does not improve students' practical skills. Despite this situation, home economics has attempted to broaden students' practical knowledge and has enabled them to acquire procedural knowledge as its main objectives in the context of the entire life. To overcome this problem, this study attempts to demonstrate the lesson model utilizing the storytelling where the lively participation in the process and results of learning can increase learners' self-confidence and responsibility. This lesson model is believed to facilitate the communication among participants including teachers and students. Through this alternative teaching method, learners can participate in the process of learning so that they can acquire practical knowledge: this method can be a step-stone for further development. In conclusion, the development of curriculum and lesson plans should be encouraged.

This study, using Fractal theory, aims to examine the meaning in the aspect of urban spatial structure by reflecting the characteristics of elements organizing the urban space and at the same time measuring the urban form quantitatively. By calculating Fractal Dimension to Cheongju as a target, it conducted comparison and analysis by dividing building and road which are internal element of a space into the whole city and urbanized area to compare and analyze validity of the theory application and the inside of an actual urban space. For the method of an analysis, it calculated Fractal Dimension by linking a digital map including the property of building and road with GIS program and using box counting. An analysis result showed that the result value of Fractal Dimension by structure and road is all high and similar. It drew a similar result value from the whole Cheongju and the urbanized area as well, but commercial and industrial area showed low result value from the partial viewpoint. However, it is correct to regard these spaces as one space because they are intimately connected with a residential area. From the general viewpoint, it could be said that Cheongju's Fractal Dimension grows in the context of a urbanized area.

This study compared and analyzed the spatial division function and role of partitions by comparing the entire space and the spatial changes before and after the installation of partitions in <Donggwoldo>, which was manufactured in the late Joseon Dynasty. As a research method, a set standard was prepared to decompose the space of <Donggwoldo> into a unit space, and the standard was set according to the role and height of the space by classifying it into a main space, sub space, and transition space. Two convex maps were prepared according to before and after the installation of the Panjang, and the values of connectivity, control, and integration, which are spatial syntax variables, were calculated and analyzed. The results of the study are as follows. First, the partition in <Donggwoldo(東闕圖)> did not affect the overall spatial arrangement and control or connection of Donggwol, but the movement and access of space is limited to specific areas. Second, the partition was a facility intensively distributed in Naejeon(內殿) and Donggung(東宮) to be used actively in the way of space utilization. It shows that the unit space increased rapidly due to the installation of the partition. Since the partition was installed in the spaces that were open and under high control in the case of Naejeon(內殿), it helped to secure private spaces as closed ones under low control. On the other hand, for Donggung(東宮), the spaces were compartmented and divided with the partition to guide the movement path through narrow gates of the partition and increase the depth of the space. This helped to create spaces that are free and can be hidden as it increased the number of spaces coming through. Third, In addition to the functions of "eye blocking, space division, and movement path control" revealed in prior research, the partition has created a "space that is easy to control" within a specific area. The installation of the partition reduced the scale through the separation of spaces, but it occurred the expansion of the movement path and space. Also, the partition functioned to strengthen hiding and closure or increase openness as well through space division. This study is significant in that it revealed the value of the spatial control function of panjang through the analysis of spatial control and depth by analyzing the function of the partition with a mathematical model in addition to the analysis and study of the function and role of panjang. In addition, it is valuable in that it has prepared a framework for analysis tools that can be applied to traditional residential complexes similar to palaces by applying space syntax to <Donggungdo> to create convex spaces according to unit space division and connection types of palace architecture and landscape elements.

Proxy Mobile IPv6 (PMIPv6) is designed to provide network-based mobility management support to an MN without any involvement of the MN in the mobility related signalling, hence, the proxy mobility entity performs all related signalling on behalf of the MN. The new principal functional entities of PMIPv6 are the local mobility anchor (LMA) and the mobile access gateway (MAG). In PMIPv6, all the data traffic sent from the MN gets routed to the LMA through a tunnel between the LMA and the MAG, but it still has the single point of failure (SPOF) and bottleneck state of traffic. To solve these problems, various approaches directed towards PMIPv6 performance improvements such as route optimization proposed. But these approaches add additional signalling to support MN's mobility, which incurs extra network overhead and still has difficult to apply to multiple-LMA networks. In this paper, we propose a improved route optimization in PMIPv6-based multiple-LMA networks. All LMA connected to the proxy internetworking gateway (PIG), which performs inter-domain distributed mobility control. And, each MAG keeps the information of all LMA in PMIPv6 domain, so it is possible to perform fast route optimization. Therefore, it supports route optimization without any additional signalling because the LMA receives the state information of route optimization from PIG.

Fault localization plays a significant role in enormous distributed system because it can identify root cause of observed faults automatically, supporting self-managing which remains an open topic in managing and controlling complex distributed systems to improve system reliability. Although many Artificial Intelligent techniques have been introduced in support of fault localization in recent research especially in increasing complex ubiquitous environment, the provided functions such as diagnosis and prediction are limited. In this paper, we propose fault localization for self-managing in performance evaluation in order to improve system reliability via learning and analyzing real-time streams of system performance events. We use probabilistic reasoning functions based on the basic Bayes' rule to provide effective mechanism for managing and evaluating system performance parameters automatically, and hence the system reliability is improved. Moreover, due to large number of considered factors in diverse and complex fault reasoning domains, we develop an efficient method which extracts relevant parameters having high relationships with observing problems and ranks them orderly. The selected node ordering lists will be used in network modeling, and hence improving learning efficiency. Using the approach enables us to diagnose the most probable causal factor with responsibility for the underlying performance problems and predict system situation to avoid potential abnormities via posting treatments or pretreatments respectively. The experimental application of system performance analysis by using the proposed approach and various estimations on efficiency and accuracy show that the availability of the proposed approach in performance evaluation domain is optimistic.

The advertisement is an informative product in which a company or an organization has made a substantial capital investment in order to achieve their goals based on their carefully thought-out plans. David Ogilvy maintaned that making a headline of an advertisement is worth 80 percent completion of the advertisement. As he insisted, a headline is also the most important element in the printing advertisement. Therefore, the importance of selecting headline's font style is increased because, while creating a headline, it is necessary to consider the emotional aspects of the advertising object that attract the attention of people. Many researchers call 'typography' as 'frozen sound' or 'written sound' because typography not only works as a letter but also provide people with an emotional pleasure. An appropriate selection of headline's font style in the advertisement production makes both the client and the audience for the advertisement satisfied because it reduces the communication risk and makes design results more reasonable. It is difficult to find many decision-making methods for selecting headline's font style. Therefore, the author of this paper investigated the trend of the use of headline's font style in order to help the designer understand headline's font style as one of design factors. As a result of the research, it is possible to conclude that, while selecting the headline's font style, the attributes of a font consist of limited style, and more objective and systematic font selection methods are necessary.
