The purpose of this paper is to examine the structural relationship between the use of a web medium and learning commitment to develop creative talent for higher media integrated Korean classical literature education. For this we used DBs of The 'Encyclopedia of Korean Local Culture(a local culture DB)' built by the Academy of Korean Studies, and a survey was conducted on 418 high school students, attending a classical literature class which used a local culture DB. The result of this study demonstrates media usefulness of local culture DBs' positive effect on learning commitment. Specifically, media richness and media experience affects the learning commitment through the medium usefulness. These results indicate that in order to encourage learner's medium experience and increase medium richness it is necessary to increase the utilization of mediums, such as local culture DBs.

As real-time media applications based on IP multicast networks spread widely, the end-to-end QoS (quality of service) provisioning for these applications have become very important. To guarantee the end-to-end QoS of multi-party media applications, it is essential to monitor the time-varying status of both network metrics (i.e., delay, jitter and loss) and system metrics (i.e., CPU and memory utilization). In this paper, targeting the multicast-enabled AG (Access Grid) group collaboration tool based on multi-Party real-time media services, a hybrid monitoring scheme that can monitor the status of both multicast network and node system is investigated. It combines active monitoring and passive monitoring approaches to measure multicast network. The active monitoring measures network-layer metrics (i.e., network condition) with probe packets while the passive monitoring checks application-layer metrics (i.e., user traffic condition by analyzing RTCP packets). In addition, it measures node system metrics from system API. By comparing these hybrid results, we attempt to pinpoint the causes of performance degradation and explore corresponding reactions to improve the end-to-end performance. The experimental results show that the proposed hybrid monitoring can provide useful information to coordinate the performance improvement of multi-party real-time media applications.

Objectives: This study was designed to understand the association between sociodemographic characteristics, health behaviors and channels retrieved for health information. Methods: Questionnaire survey was performed from April 2007 to May 2007 through household visiting. Sample was selected according to gender, household income, and residence district. We got 1,009 respondents and subgroups were as follows; 508 people had health insurance, 250 people were medical indigent group, and 251 people were medicaid beneficiaries. Results: People seemed to be separated into subgroups by channels used for health information. One was active and the other was passive group. Characteristics of passive group were older age, worker or inoccupation, less income, subjective poverty, lower education, loss of spouse, medical indigent or medicaid group. They usually got health information through mass media like TV and radio or medical professionals. Characteristics of active group were younger age, professional, more income, subjective affluence, higher education, single or married, and member of health insurance. They mainly got health information through printed media like newspaper or the Internet. Conclusion: We suggest to provide health information through various channels customed to individual needs and literacy. Public health stakeholders seems better to focus on people with low education, insufficient health literacy, poor health status, and short information technology.

This paper examined the utilization pattern of aroma-therapy and relating factors after visiting about 100 skin-care shops registered to the Central Estheticism's Association in Daegu.Kyungbuk areas, in 200. This questionnaire survey was put into practice from September 1st to September 30th, 2003 for one month, study subjects were 643 skin-care-shop users. As for the experience of Aroma-use. while 85.4% of respondents experienced Aroma-use or has been using Aromat, 14.6% had no experience of Aroma-use. As for average frequency of Aroma-use, 32.8% used Aroma one time a week,23.7% everyday, 20.4% one time a month, 12.0% 3 times a week, 11.1% 2 times a week. As for the route of getting information on aroma, 49.5% of Aroma users got the information in skin-care-shop, 28.6% from mass-media such as internet, TV, newspaper, magazine. Regarding the type of preference aromas, 65.4% answered Lavender, 35.3% Rosemary, 35.2% Peppermint, 25.5% Rose, 23.7% Tea tree, 21.1% Jasmin, 19.5% Lemon. As for purposes of Aroma-use, 36.8% answered problematic-skin-control & fatness-control, 33.5% stress-relaxation, 14.8% physical-symptom-relaxation, 12.4% muscle-relaxation, 2.6% other purposes.

Continuous multimedia applications require a guaranteed retricval and transfer rate of streaming data, which conventional file server mechanism generally does not provide. In this paper we describe a dynamic negotiated admission control and dick bandwidth scheduling framework for Continuous Media (CM : e.g., video) servers. The framework consists of two parts. One is a reserve-based admission control mechanism and the other part is a scheduler for continuous media streams with dynamic resource allocation to achieve higher utilization than non-dynamic scheduler by effectively sharing available resources among contending streams to improve overall QoS. Using our policy, we could increase the number of simultaneously running: clients that coo]d be supported and cot]d ensure a good response ratio and better resource utilization under heavy traffic requirements.

This study was conducted to determine the effects of adolescents' media literacy, self-esteem, and cognitive related to on critical media understanding ability using data from the Korea Media Panel Survey 2020. As a result of the study, PC literacy and smart device literacy influenced adolescents' critical media literacy. The mediating effect of cognitive needs between Internet literacy and critical media understanding ability using PCs and smart devices was significant, and the mediating effect of self-esteem between email literacy using PCs and smart devices and critical media understanding ability was significant. Therefore, to improve adolescents' critical media understanding ability, it is necessary to educate them to use PCs and smart devices as tools for interaction. To this end, it is desirable for information and technology subjects to focus on media literacy to increase cognitive needs, and for other subjects, cooperative learning using media is desirable.

One of celebrities using Social media caught public's eye and interest in Korea. Thereby the number of the user has grown rapidly and by last year it had reached to about 770 million. But at the same time, it has brought us social issues such as invasion of privacy, spreading of malicious code, and stealing of ID. To solve these problems, first the government need to establish adequate law and policy. Second, Service provider should remove vulnerability in the security system and filter illegal information. Third, individual user should put more effort to protect their own privacy. This paper will suggest a solution of using the Social media more sound and secure.

On 11 March 2011, earthquake occurred in Japan were left with the significant human and material damage. Among these, social media has emerged as a very useful communication channel by playing a important roles in the process of safety checking and disaster recovery. In fact, however, we have no specific response methods or systems to these occurrence of disaster in Korea. Therefore, we investigate the relevant literature in order to analyze the current status of foreign and domestic utilization of social media, and draw the ideal ways to use social media for responding to unpredictable disasters based on the relevant literature reviews. The results of this study are summarized as follows. First, Institutions such as Meteorological Administration or National Emergency Management Agency are able to utilize social media as the communication systems to public in emergency. Second, social media are able to used for building disaster information systems including location information such as emergency call for help or requests for dissemination materials. Lastly, online donation services via Facebook or Twitter are able to be provided. The findings have significant implications for official responsible for disaster response and academic researchers.
