Radio waves including GPS signals, various TV communications, and radio broadcasting can be disturbed by a strong solar storm, which may occur due to solar flares and produce an ionospheric delay anomaly in the ionosphere according to the change of total electron content. Electron density irregularities can cause deep signal fading, frequently known as ionospheric scintillation, which can result in the positioning error using GPS signal. This paper proposes a detection algorithm for the ionosphere delay anomaly during a solar storm by using multi-reference stations. Different TEC grid which has irregular electron density was applied above one reference station. Then the ionospheric delay in zenith direction applied different TEC will show comparatively large ionospheric zenith delay due to the electron irregularity. The ionospheric slant delay applied an elevation angle at reference station was analyzed to detect the ionospheric delay anomaly that can result in positioning error. A simulation test was implemented and a proposed detection algorithm using data logged by four reference stations was applied to detect the ionospheric delay anomaly compared to a criterion.

Along side with the rapid growth of local governments' advertising bills, there are few studies focused on the effectiveness of these ads. Especially one of the media being used by the local governments is the Korea Express Train (KTX), where they advertise in the train coaches' KTX video monitor. Unfortunately the ads in KTX are exposed without audio mostly. The current study, therefore, probed on the effectiveness of these ads. This study utilized transportation theory and content analysis methodology to give insight to its discourse. We established two analysis units (camera and subtitles), and then analyzed 107 local government ads. From the camera analysis, it is observed that local governments' festival and tour promotion ads more often employ dynamic angles such as drone shot and long shot. Also, from subtitles usage analysis, it is observed that many of the ads make use of large size titles and subtitles which could prevent viewers seeing visual shots. In the special case audio-less KTX ads, this study recommends emphasis on subtitles which will enhance the ad effectiveness of the ad messages.

The emphasis in environmental education for children should be on awareness, appreciation, and sensory experiences. By offering children opportunities to experience the elements of nature that surround them, teachers elevate children's comfort level and familiarity with the natural world. But many children have little contact with nature, because of urban living, hurried schedules, TV's attraction, and the low value most schools place on outdoor activities. So, teachers have to expand the real out-of-door experiences into the classroom by sharing and making accessible books focusing on nature and the natural environment. Namely, quality children's literature is an excellent vehicle for extending a particular experience or introducing new ones. Building on outdoor experiences through stories encourages children to explore more deeply what they have observed and experienced-concepts are reinforced, new knowledge gained, vicarious experiences provided. There are three-fold classification of environmentalism, especially environmental ethics, and three-aspects of the history in children's literature. The analytical results of this study are as follow. The environmental ideology in elementary Korean textbooks varies from 'egocentrism-didacticism' to 'ecocentrism-fantasy'. This finding has implication for selecting children's books and teaching environmental contents in elementary school. Therefore teachers and parents need to get ready to receive ecocriticism.

As social media has become a part of daily life, new types of online opinion leaders are emerging, and in turn, changes in traditional fashion leaders and leadership are expected. Considering such changes, this study attempted to reexamine fashion leader types and influence characteristics from the perspective of college students as fashion followers. Students were asked to write an essay identifying their fashion leader and how and why they were influenced by him or her. Sixty essays entitled "My Fashion Leader" were collected and content-analyzed. A total of 78 fashion leaders were identified and categorized into four types including celebrities, social media influencers, friends/family/acquaintances, and people seen on the street in order of frequency. Influence characteristics of the identified fashion leaders included superiority, role model, similarity, and familiarity. Similarity was observed across all types of fashion leaders, while superiority and familiarity were identified for celebrities and friends/family/acquaintances, respectively. The results imply that celebrities, mostly those from the TV, movie, and music industries, are still important as fashion leaders in society regardless of their communication style, while friends/family/acquaintances as opinion leaders within a consumer group are important to provide information, advice, and help. However, social media influencers between the two groups are expanding the influence.

SBS [Healing Camp] seems like having a different sound usage from other entertainment programs. After content analysis, I found that [Healing Camp] uses much more music & sound effects than [Muhandojeon]. Music & sound effects of [Healing Camp] has functions of tautological informing, uplush of emotion or Ancrage, narrating or Relais. It is very similar to television subtitle. Positive uses of music & sound effects are expected to catch the attention of audience and to increase the ratings. But [Healing Camp] uses music & sound effects very positively and systematically and opens a new dimension of narratives.

Digital Multimedia Broadcasting (DMB) is the mobile TV service based on a digital radio transmission system that provides high quality audio/video and other auxiliary data services. As users want to store the DMB content in their device to be consumed later or to be shared among users, a standardized format needs to be specified to guarantee the interoperability for the DMB contents for various devices. DMB AF (Application Format) specification defines a file format for DMB contents and services. It specifies how to combine the variety of DMB contents with associated information for a presentation in a well-defined format that facilitates storage, interchange, management, editing, and presentation of the DMB contents in protected, governed, and interoperable ways. In this paper we present our implementation of DMB AF as part of the development of DMB AF reference software. Our implementation of DMB AF is developed as the reference software for the standard specification that consists of a three applications: packager, media player, metadata browser and collection of supporting libraries used by the applications.
