  • Drones, which were originally developed for military purpose, have expanded rapidly not only in hobbies, leisure, but also in broadcasting, filming, and public sectors, and search and rescue drones have been used to find four Korean teachers who went to Nepal for volunteer work but went missing in the avalanche. The government is encouraging the use of drones in the public sector as a policy to foster the drone industry, and the market is expected to expand in the future. This study presents improvement measures and specific directions for use of drones by public agencies at a time when the use of drones is expanding in the public sector. To that end, this research reviewed the interviews of relevant experts, analysis of drone operation regulations by public agencies, and the cases of operation of drones for searching missing persons by police. First of all, it will have to secure skilled personnel before the introduction of the drones and then determine the specifications of the drones through sufficient review, and then be put into the mission after careful examination of the drones. Next, it is necessary to draw up a base rule for drone operation and draw up a manual accordingly. Finally, drone flight has the risk of a crash, and it is essential to secure dedicated personnel for drone operation, especially since drones in the public sector are specialized in large scale compared to hobby drones to achieve their purpose. This research only conducted a detailed analysis of the National Police Agency's drones for searching for missing persons, and there are limitations to the number of people interviewed. Subsequent studies will require analysis of various public institutions, and in addition to interviews, surveys will require analysis of various data and statistics.

  • For the success of the DMB market to meet consumers' demands for Ubiquitous Media and strengthen the nation's competitiveness, it's inevitable for us to activate DMB advertising as of main profit source for DMB Media, and to develop various types of DMB advertising which are linked to the profit model. So I'd like to look over the various types of DMB advertising which are suitable for DMB features as one of the efforts to activate DMB advertising. First of all, I've figured out what kinds of advertising are available for new media and which related technologies are required for DMB media. Through this research, I could find out what features of new media such as cable broadcasting, Internet and Mobile have become the source of developing various types of advertising and how to a great part to activate new media advertising markets by making the best use of their media features. This research also shows that DMB advertising has the high potential to be developed in various and effective types and kinds of advertising with its media feature and technological feature. This research observing DMB advertising cases showed that DMB advertising can be divided into 6 types such as forms, purposes, techniques, advertising positions, the use of LBS(Location Based Service), coupons and it could be developed into various kinds of DMB advertising dependent on each type. On the other hands, it would be great to have continual researches and follow-ups for various types of DMB advertising and the verification of the effectiveness for DMB advertising by performing potential DMB advertising.

  • What is an appropriate length of an article in the mobile era producing new tastes of contents combining computing and mobile communication? Is it still valid to have a lengthy article as high level journalism even in the mobile era? Is there any possibility to have a short article combination to give us readability and the amount of information? This study aims to find some answers to these questions. The length of articles were controlled with a field experiment; from an article of 346 syllables(including spaces between syllables) which does not need finger scrolling on a mobile phone to articles of 633, 1033, 1368 syllables(including spaces between syllables) which frequently appear in newspapers and broadcasting news program. All the main themes were same for 4 articles which have different length. Three hundred and eighty four students viewed one of the 4 articles through mobile phone or newspaper. Each participant checked their preference and evaluated quality on the article, were asked to recall contents of the article. In newspaper group, articles with 346 or 1033 syllables were highly evaluated. Mobile group seemed to prefer articles of 346 or 633 syllables. In conclusion, we need to consider various strategies shortening the length of an article into 346 or 633 syllables as a basic format to meet the neEds of mobile era.

  • The purpose of this study was to investigate the needs of educators, learners and parents in elementary schools for implementing a systematic nutrition education program by nutrition teachers to begin in 2006. The subjects were 833 dietitians, 808 principals, 3,141 teachers, 7,577 students and 6,003 parents in elementary schools. A fairly large proportion of the principals (98.4%), teachers (95.5%), parents (96.6%) and students (62.8%) responded that nutrition education is urgently needed. Every dietitian, principal and teacher has recognized that for the enforcement of a nutrition program in the future, the placement of one nutrition teacher in every school is needed without a moment's delay. Many subjects responded that elementary low grades are the most proper time for nutrition education for students and it is also needed to extend this not only to students, but also parents and teachers who have a direct influence on them. In the education hour, they responded that it is proper one hour a month for teachers and one hour a week for students. Fifty-six percent of dietitians, 58.3% of principals and 67.0% of teachers responded that the best educational way to heighten the effect of nutrition education was education through discretional activities. It was found that 46.4% of students have wanted nutrition education to be enforced during special activities. Education through their school homepage or in-school broadcasting system, while it has been most utilized, was low in a degree of preference with 10.9%. In regards to a nutrition program, principals and parents have attached much importance to the dining etiquette, dietary attitudes, and relations of foodstuffs with health, while dietitians and teachers have made much of a balanced eating habit, and the relations of dietary life with health. Finally, for a nutrition program to be enforced towards a direction that the educators and students want, it is judged that first of all the role of nutrition teachers is the most important, furthermore the support of manpower and the budget should be made.

  • This study was to look into the press policy and the related activities performed by North Korea in the South during the Korean War and to evaluate them. In order to understand the concrete contents of the activities and their characteristics, the two representative newspapers published in the South by North Korea at that times - the Chosuninmin Bo and the Haebang Ilbo - were reviewed and analyzed. North Korea operated broadcasting and started newspapers just after the possession of Seoul. and also performed various positive press activities - such as the distribution of the newspapers and periodicals of North Korea and U.S.S.R., putting the movies on the screen, and founding the weekly, etc. But the target of all the media were the same. It aimed to support Kim Il-Sung's scheme which intended to carry out the war successfully and to make the South under occupation Communism System by introducing the Northern law and system. The two newspapers, as agent of power, made only such a role to agitate and exaggerate the false things with unrealistic optimism. They intended to ideologically mobilize the South people and to affect on their perspectives and acts. However the media including the two newspapers being operated in the South during the war had not got the faith or the good response from the South people as an audience. Most of South Koreans were tired with their endless and one-sided propaganda, agitation and ideological enlightenment. It could therefore be evaluated that the press activities by North Korea in the South during the Korean War resulted with many limitations in ideologically organizing and mobilizing the South Koreans.

  • The convergence of media poses serious challenges to technologies, industries and policy makers. At the core of the challenges lies a socially and culturally problematic condition of 'media unlimited.' Under the circumstances, the idea of public interest of the media seems to lose its intervening leverage as it flounders in countering 'the media torrent' rushing from the exponential growth of ICTs that overwhelms contemporary life and society. It is an urgent task for the critical community to blaze fresh new thoughts about the idea to intervene in the current age of media excess. Beyond the conventional content-conduit-centered perspective on the media, this study suggests a media-environment concept based on media ecology as an engaging leverage to replenish the public interest idea. The environmental approach to the media means literally to conceptualize the media as environment--a cultural eco-system. This study explores the potential of ecological approach in enriching the conceptual terrain of policy discussions and policy-making processes concerning the public interest idea that hopefully enlightens all the media actors concerned.

  • This study was conducted to analyze how appropriate the on-line nutrition information was externally as a web information. Four-hundred-ninety-seven web sites from 5 internet search engines (Yahoo, Empas, Nate, Hanmir, Naver) were selected on the basis of April 25th, 2004. The skillful personnels monitored them about 8 evaluating categories: clarity, purpose, authority, durability, advertisement, privacy and/or security, responsibility, and contents. Forty percent of the selected web sites were operated by the companies which had commercial purpose like internet shopping malls and 5.6% by academies, societies, research institutions, schools/colleges and public institutions. Most of web sites (76.1 %) were managed for advertisements and sales of companies' commodities, and 32.6% had the food and nutrition information as first purpose. Ninety-three percent of web sites were targeted to healthy individuals through whole life cycle. Specifically, there were lots of web sites for the obesity which were offered by diet related companies. Of the 497 web sites, 193 mentioned the name providing the nutrition information, but only 1/3 had reliability on their specialty. As a source of nutrition information, 52.7% of web sites were using 'books of the major field' and 42.0% 'newspapers' and 23.7% 'broadcasting', respectively. Most web sites mentioned 'setting-up date' but not 'renewal date'. Thirty-six percent of web sites took '2 - 3 days' for the operators to answer the questions through the bulletin. Forty-seven percent of web sites answered' 1 - 10 questions' per 1 week, but 40.1 % of them didn't answer for a week at all. There were 118 web sites (23.7%) to record the connected frequencies and 36.0% of them put the advertisements. Around 96% of web sites mentioned feedback addresses. Among the menus of web sites, 68.0% were about self-advertisement and 64.0% about nutrition information. Each web site was scored to judge its external quality according to the operators by selecting 13 items. Web sites managed by public institution had highest scores (9.5), and lowest in private vendors', food companies' and individual web pages. Among search engines, Naver got the highest score of 7.0 and Nate the lowest one of 6.1. As it was only the pilot study, there were several limits in evaluating tools, time and monitored quantity. To make monitoring of on-line nutrition informatiions actively, standardized monitoring forms might be developed under the integrated studies.
