In this paper, we develop the system for audio volume equalization of video on demand(VoD) content and propose the solution for it. In recent years, there has been a steady increase in the number of VoD users in addition to linear channels. However, viewers ought to sit in an uncomfortable way, adjusting the volume intermittently while they are broadcasted. Sudden changes of volume occur between the broadcasting channels, the programs from the co-channel, or the linear channels and the VoDs. Especially, upsurged dissatisfaction from the televiewers has been found due to the unequalized volume when shifting between the linear channel and the VoD. In order to solve this problem, multilateral efforts were put forth, such as a system for keeping the volume at a certain level in digital broadcasting program has been legislated domestically. It leads success in equalizing linear channel volume. On contrary, too little notice has been taken for distorted volume problem of video on demand(VoD) content. In this paper, we developed and applied the volume equalization system into VoD content to achieve uniformization, a similar condition with linear channel(-24LKFS). This suggestion helped uneven current of volume which was in the stage -16 ~ -20LKFS to stable condition by lowering into the stage of -24LKFS. It also brought 20% increase in perspective of volume quality satisfaction level.

Since IMF relief financing, domestic economy has been rapidly cooled down. At this point that we predict an overall decrease of production and sale of industries, cooperative marketing activities of the whole dairy industry are required to promote milk consumption. As everyone knows, advertisement is only one of the various factors that affect sales. Other factors include price, distribution, package, promotion, and consumer's needs and taste. The objectives of the cooperative advertising campaign should be trial purchase of new consumers, maintenance of brand loyalty of existing consumers, more positive experience of using the product, and increase of frequency of purchase. Long term analysis is essential to making these kinds of behaviour changes. Also the objectives of the communication program should be a shift of awareness of milk from 'a basic health food for children' to a substitute to the beverage even for adults. To share database of consumers among companies, we need to find ways to use interactive on-line services, the internet, D.M. events and so on as well as the mass media. It should be a precondition that the main body of the cooperative advertisement includes the milk processing board, dairy companies, livestock cooperations, farmers and the Government. To assure continuous, activities to promote milk consumption, the Government should take the lead in legislating 'An enforcement ordinance for milk promotion and research', and seek complementary measures and support to establish the ordinance.

Recently, as mobile internet users grow rapidly, mobile internet companies are experiencing a fierce competition to capture new customers. Under this business environment, they try to identify factors that make people use mobile internet in order to satisfy customers by providing better and diversified services. There has been enormous effort to analyze customers' behavior in choose and use mobile internet services. However, there is no one best methodology to identify factors to attract customers yet. Thus, the study applied the flow construct proposed by Csikszentmihalyi(1977) and expanded by Hoffman and Novak(1996) to identify environmental factors of internet which has impact on users' mobile internet usage. To implement the study, the following activities have been done: literature reviews on service acceptance model and flow structure, questionnaire survey, suggestion of the flow model on mobile internet, and hypothesis test. For the study, 242 out of 307 samples collected were statistically analyzed using SPSS 10.0, AMOS 4.0 statistics package. The findings of this study are as follows: First, mobile internet environment factors influencing on challenge of flow antecedent were media characteristics(use of convenience, transmission quality), contents characteristics(uniqueness, timeliness, simplicity). Second, mobile internet environment factors influencing on skill of flow antecedent were contents(uniqueness, timeliness, simplicity), charge(definiteness and diversity of charge), usage(security, instant connectivity). Third, challenge of flow antecedent had a significant effect on flow of mobile internet usage. But it was not statistically significant that skill has an influence on flow. This study discovered the relationship between mobile internet environment factors(media characteristics, contents characteristics, charge characteristics, usage characteristics) and flow experience of mobile internet users which would be a valuable insight for marketing strategies. Results shows that challenge of flow antecedent have a significant impact on flow experience in mobile internet environment. Additional, media characteristics, contents characteristics of mobile internet environment factors is positively correlated with challenge of flow antecedent. In other words, mobile internet companies should provide customers with diverse service and take a challenging attitude to get customers show aggressive attitude in mobile internet usage.

Korean Blood Services have grown with history of half a century or more, and in its developing process, technological growth have contributed largely toward it. However, Korean Red Cross and public blood centers are finding difficulty in their business because the public doesn't feel necessity of blood donation and have distrust in current blood management system. Recently, smart phone shows new possibility to the modern life as it plays a role of micro PC. With this tendency, mobile application is being highlighted as a new media. Therefore this paper aims to propose an application called 'Nanumi'(tentatively named) to improve negative awareness about blood donation. For specific development suggestion, I analyzed existing theses and applications. Also, I interviewed experts in blood management and did a public survey to firm up necessity and appropriateness of this research. In this paper, I proposed structure of functions and UI design for the application.

This study seeks to find new strategies for the development of Tapgol Park and to identify Programs to promote this development. In addition, the study specifies the purpose and meaning of these efforts by revealing social aspects not apparent in the physical form of the site, and reading how these aspects influenced the development of Tapgol Park Because the focus of the study lies in reading cultural aspects of the site which have to be understood within the context of their social circumstances, the study drew materials from mass media such as newspapers and literary magazines, which best reflect these social aspects. Interpreting the over 100 you history of Tapgol Park in a cultural context, the study found a meaningful suggestion that such a small urban place located in a city forms a cultural identity in the course of communicating with its surrounding social situations. The change in the identity of Tapgol Park has been sensitive to changing social circumstances rather than the physical structure of the space. The original function of Tapgol Park as a traditional city park has gradually changed towards strengthening social functions, much like the character of an urban plaza. In the process of change the park developed a unique culture. This park culture, however, came not from the original design but from its close interactions with social circumstances changing over time. At the same time, the change in identity seen in Tapgol Park has not been fresh formed. It can be said that the inertia came into light with the potential powers under the place over the long history having been combined into the then social circumstances. In early 2002, the park re-opened, refurbished as one of the relics of the March 1st Movement. Investigating how cultural inertias that have been developing in various forms to date will change and be maintained in this new paradigm is an important assignment for researchers.

Purpose This study suggests the development of forecasting model for local cable TV advertisement. In order to verify the expected effect of the suggestion, using the causal loop map of System Dynamics, the factors affecting the prospects of cable TV commercial market were divided into 5 groups. Then targeting 97 people involved in the cable TV commercial market in Busan, Ulsan, and Gyeongnam, a survey was conducted on their perception of the current status of local advertisement market and future prospect. Design/methodology/approach The analysis of the collected data shows that workers in advertising and advertisers perceive the influence of cable TV as an advertising media to be high, while clearly understanding the problems of cable TV commercial market. Based on this the effects on the prospects of cable TV commercial market were analyzed and a forecasting method called Weighted Moving Average was applied. In order to improve accuracy of the added value of Weighted Moving Average, the 5 factors were divided into qualitative factors and quantitative factors, and using Multi-attribute Decision Making method, all the factors were normalized and weighting factors were deduced. The result of simulating the prospects of cable TV commercial market using Weighted Moving Average, both qualitative and quantitative factors showed downward turn in the market prospect for the following 10 years. Findings The result reflects generally negative perception of advertisement viewers about the prospects of cable TV commercial market. Compared to the previous studies on domestic cable TV commercials that focused on policy suggestions and surveys on perception of current status, this study has its significance in that it used scientific method and simulation for verification.

The Information and Communication Technology(ICT) is applied variously by advanced development, however that also causes the ethical problem simultaneously nowadays. It is emphasized the necessity of information and communication ethics and the scheme also is suggested that the student actually may produce and use their own UCC as an educational material which relates to ethics of information and communication in this paper. By doing that activity, student could learn themselves from what they've produced. Therefore they can approach the subject with more interests, beside the method how teacher has been teaching normally which can be described as cramming. The suggestion is phased by the steps as below; First of all, adequate guidance is selected and the aim of education is established to the method of education through producing UCC by analyzing the contents system of information and communication ethics. Second, it is analyzed educational effect along media of UCC. Third, it is analyzed educational effect along the producing format of UCC. Finally, the scheme is developed that student could be learned from UCC they have created. Therefore, students could be participated by themselves more actively to the education and manage the negative effects of ICT. They also could acknowledge and determine the right ethical awareness of information and communication, and develop more advanced ethical awareness by doing this activity.
