The purpose of this thesis was to implement effective blended PBL(Problem-Based Learning) systems for information communication ethics education. The proposed systems, Online learning and face-to-face classes were systematically combined and Moodle is used for online learning platform. We proposed the use of wikis and blogs not just for creation of knowledge, but as active learning tool to support PBL. In the proposed system, learners used the web 2.0 as a open place to create new knowledge and experience various effects of PBL, such as (1) Improvement of problem solving ability, (2) Understanding of cooperative learning. The blended PBL systems with teaching and learning model were evaluated learners' level of satisfaction and educational achievement in the study of information communication ethics. The result shows that blended PBL learning method is more effective in cultivating consciousness of information communication ethics and showed more higher level of learners' satisfaction and educational achievement than the face-to-face PBL learning method.

Currently, depending on the penetration of the mobile device, age of one person one mobile device is open. It is a time when mobile equipment is located to the depths of human life that much. However, equipment for new mobile devices full of, was in the existing, tend to sleeping in the house or abandoned. It is determined that you build one server in a mobile device that individuals have, to be able to break out of the framework of the existing service Twitter and blogs, such as Facebook, and to create multiple Web services with a personality of their own. In this paper, we studied a scheme that can be instead of a simple fixed server, considering the characteristics of only the mobile device and take advantage.

Korean travel agencies that have been utilizing the Internet passively feel threatened as global online travel agencies are quickly permeating the Korean travel market. Under these circumstances, this study conducted a focused analysis on how ICT affects the business environment of travel agencies. Based on the analyzed data, it also presents coping strategies for the Korean travel agencies. First, it is imperative to accelerate platform development to counteract the distribution structure of global tourism products. Second, it is essential that travel agencies actively utilize big data, the new paradigm of technology where data are generated at high speed, high volume, and for numerous purposes. Third, it is necessary to actively utilize a travel blog marketing strategy. As a communication tool for travel agencies, the continuing development of the Internet highlights the usefulness of marketing activities using blogs.

In emergency dispatching at 119 Command & Dispatch Center, some inconsistencies between the 'standard emergency aid system' and 'dispatch protocol,' which are both mandatory to follow, cause inefficiency in the dispatcher's performance. If an emergency dispatch system uses automatic speech recognition (ASR) to process the dispatcher's protocol speech during the case registration, it instantly extracts and provides the required information specified in the 'standard emergency aid system,' making the rescue command more efficient. For this purpose, we have developed a Korean large vocabulary continuous speech recognition system for 400,000 words to be used for the emergency dispatch system. The 400,000 words include vocabulary from news, SNS, blogs and emergency rescue domains. Acoustic model is constructed by using 1,300 hours of telephone call (8 kHz) speech, whereas language model is constructed by using 13 GB text corpus. From the transcribed corpus of 6,600 real telephone calls, call logs with emergency rescue command class and identified major symptom are extracted in connection with the rescue activity log and National Emergency Department Information System (NEDIS). ASR is applied to emergency dispatcher's repetition utterances about the patient information. Based on the Levenshtein distance between the ASR result and the template information, the emergency patient information is extracted. Experimental results show that 9.15% Word Error Rate of the speech recognition performance and 95.8% of emergency response detection performance are obtained for the emergency dispatch system.

With the advance of information technology, e-learning is widely used. However, due to the lack of human computer interaction, e-mentoring or blended learning are adopted to complement the drawbacks of e-learning these days. One of the common purposes for adopting these tools is to enhance the interaction level by using bbs or blogs based on e-communities. If the cooperative learning contents management tools that share learners' knowledge in e-learning are provided, interactivity and educational effects can be enhanced. In this paper, a tree-based learning contents construction tool and a community-based cooperative learning contents construction tools that can share the learners' knowledge are proposed. Also, we analyze the influencing factors to the learners by using the proposed tools.

In the past, strong social bands, which had spontaneous communities, existed in Korean traditional society. However, while it's developing through industrialization; monolithic apartment houses were introduced which causes less interaction between neighbors. With the growing attention to the higher living quality, various schemes to revitalize the community spirits have been groped, including to improve in hardhearted neighborhood relationships and to cope with the dreariness in the city. With the development of the internet and the spread of 'digital home', the communities in cyber space have been especially revitalized since the information-oriented society. In a move to strengthen the communities in apartment complexes, this study tries to find the revitalization scheme for virtual communities in apartment complexes by analyzing the contents of its web sites and understanding the world of virtual community. These are compared and analyzed. The related virtual communities ("cafe" or "blogs") are also analyzed. The results are as follows. 1) There are some differences among the contents provided by apartment virtual community developing companies, still, it could be categorized into four types; "apartment complex introduction and management information" "community revitalization" "living guide" "individual services" 2) The contents provided by self-organized communities of residents neither require additional charge nor special membership for information while the formation is not systematized. 3) In the comparison of apartment virtual community developing companies with residents self-organized communities, "apartment complex introduction and management information" on freeboard, notice, request and Q&A, and "community revitalization" on communication board are both provided throughout the web sites. 4) The contents provided by apartment virtual community developing companies makes the information available in a wide range with managers, on the other hand, self-organized communities emphasize on showing attachment and concern of residents and requiring communications between neighborhoods.

When it comes to museumification, it has often been approached in terms of false history, placelessness or simulacra. However, this research aims at exploring the relation between the bodily-spatial performance of walking in the city and the museumification of urban space. For this, first it reviews theoretical discussions of walking as a bodily-spatial performance. Then, in the case of Daegu's Modern Street Tour and particularly focusing on the tour map, it looks at how the bodily performance of walking constructs the urban space of the tour as a museumified space. Finally, seeing the participants' blogs and other websites as another performative space, it examines how the bodily performance of walking reproduces the discourse and space of the tour in virtual space as well as in actual space. The study suggests the elusive assemblage of heterogeneous and multiple time-spaces immanent in urban space, which is different from the absolute and linear order of time-space in museum space.

This study examined the impact of information and communications technology (ICT) on the sociocultural dimensions of the family by comparing ICT use in Korean, Chinese, and American families. This study investigated attitudes to ICT usage in the family context by country and explored how various consumers use ICT in the family context. The study explored how families can be clustered based on usage. ICT device ownership had differences in the use of ICT services including blogs and video chatting accounts. ICT usage in the family was also similar in all three countries in the study, but the depth of use differed. The cluster analysis indicated that users could be classified into four groups, however the proportion in each group differed by country. This study has implications for understanding ICT ownership and use by families in various countries and indicates that sociocultural elements are important in ICT use.

The number of digital camera users is increasing rapidly and countless number of photos floats about on the internet especially through wide-spreading Cyworld and blogs. Though portraits cover a large percentage of those photos, because of the property rights, near entirety or such photos are unavailable for use by web-page producers, advertising companies, web-designers, and so on, who need a variety of portraits with differing expressions and characteristics. This study offers a search engine that incorporates image characteristics based on natural language index, which can provide a fast and reliable search result. It will create an opportunity for the digital photographers to mure easily sell their pictures and simultaneously provide the would-be users of the photos a better and easier way to find the pictures they are looking for. Once the search engine is realized, it will become possible to use not only the nouns as keywords and categories but also verbs in search of portraits revealing feelings, expressions, dressings, and other characteristics.
