This paper deals with the optimization problem that decides the number of advertising for any media among various medium to maximize the perception quality index of new product meets the given budget and over the minimum reached people constraints. For this problem, there is only in used the mathematical approach as linear programming (LP) software package and has been unknown the polynomial time algorithm. In this paper we suggest the heuristic algorithm with O(nlog n)time complexity to solve the optimal solution for this problem. This paper suggests the evaluation index to select the media most economically-efficient way and decides the media and the number of advertisement. While we utilize Excel, the proposed algorithm can be get the same optimal solution as LP for experimental data.

Library Week was established in 1964 and has continued without interruption for 56 years. It has grown to become one of the largest and most important activities within the library field today. The Korean Library Association publicly selects slogans to be used for Library Week publicity purposes and their poster advertising campaign. A study and evaluation analyzing slogan contents was performed to determine the overall effects of these slogans on the public and provide suggestions for more effective and focused slogans as part of a branding strategy. To achieve this purpose, the contents of 116 official slogans of the library week were analyzed according to the linguistic techniques and key words suggested by Young-Jun Park (2001). As a result, there were 103 slogans (88.79%) composed of only 'Korean characters'. And the key scoring type with the highest number of hits was the word 'sentences' 46 units (39.66%). Furthermore the word in the slogans resulting in the highest number of hits was 'library' with 111 units (96.52%). Therefore, it can be said that most of the weekly slogans of the library are 'sentence type' consisting of 'Korean characters' containing the word 'library'.

The result of analysis, news on lottery game mainly has been reported social issue related with win such as 'winning number', 'prize money', 'suspicion of manipulation' and etc. News on sports betting has been reported mandatory information related with business project and illegal site such as 'bidding', 'illegal site', 'sales target' and etc. News about horse racing has been reported the information about the business advertisement such as 'online race track' and 'promotion'. Lastly, casino related news has been reported 'major information' such as illegality', 'gambling place' and 'foreigner'. As a result of times series analysis, news about casino in the 1990s, news about lottery in the 2000s and news about horse racing in 2010s have been increased. Public's interest also has been moved to 'business scandal', 'winning game', 'citizens' campaign' and etc. Gambling related news has been classified by four types, 1. advertising publicity(horse racing), 2. mandatory information(sports betting), 3. social issue(public agenda, lottery), 4. major information(casino). We could get the insight that news can be formed a public agenda, when news is reported as a social issue with high frequency and public's interest like lottery related news.

The media movement is a movement to separate from the political power and to dismantle the media power and to seek the control of citizens' media. Political power is the biggest factor that violates the fairness and independence of the media in the public domain. On the other hand, the factor that interferes with the healthy and responsible media of the press in the private sector is the media power originating from the owner. Citizens 'media campaign emphasizes citizens' mobility as a subject that monitors the political power and media power that have the sovereignty of the media belonging to the citizen and may infringe on this sovereignty.In the Lee Myung Bak - Park Geun Hye regime, the civil press movement was a period of resistance and struggle. Citizen media campaigns have completely collapsed with governance. As a result, the intellectuals who have expertise in the media have lost their place in the discussion and presentation of the policy alternatives in which the policy production is centered. The influence of citizen media organizations, which are centered on activists rather than citizen's direct action, is limited. In order to strengthen the power of the media reform, it is necessary to reconstruct social forces such as civil society, media unions, media organizations and political forces. We should also look for various ways in which citizens can participate actively in the agenda and activities of the movement. In addition, it is necessary to expand the movement of the media.
