The world's major countries carry forward strategies for enhancing industrial competitiveness, resulting in the fourth industrial revolution while a new growth engine is required to deal with the slow growth of global economy and declining productivity. Artificial intelligence (AI) is regarded as a core technology of the fourth industrial revolution. AI is expected to be implemented rapidly in advertising and media industries. However, it is hard to find an effective way to implement AI in these industries, especially because of how quickly the AI market changes and develops. Therefore, this study seeks the possible industrial influence of AI in advertising and media industries and invigoration plan for AI, by an in-depth interview with 10 professionals who lead the AI market. First, it was analyzed to explore the macroscopic side of the AI market through P (Politics), E (Economy), S (Society), and T (Technology). Also, the applicability of AI in advertising and media industries was explored by analyzing its S (Strength), W (Weakness), O (Opportunity), and T (Threat).The result indicates that it is necessary to build up a nation-wide construction of infrastructure for the fourth industrial revolution to invigorate AI in advertising and media industries. Moreover, a social environment capable of overcoming a hyper-connected society and social risks should be fostered. Lastly, it is urgent for both the industrial and academic world to diagnose the influence of AI in advertising and media industries, to anticipate the future in accordance with technological advance, set a proper direction, to invest actively for technical development of AI, and to formulate innovative policies.

This article aims to identify organizational factors that influence the performance of implementation of the U.S. Freedom of Information Act (FOIA) and to investigate the strength and direction of their effects. Explanatory variables include administrative resources, organizational culture, litigation cost, and the complexity of FOIA requests. The study will analyze quantitative secondary data from official statistics of federal agencies and the 2006 Federal Human Capital Survey as well as qualitative data from semi-structured interviews of FOIA officers. The results of statistical analyses are as follows : FOIA funding significantly affects median processing time and number of requests pending. There is a significant relationship between bureaucratic culture and number of requests pending, but not between bureaucratic culture and number of requests pending. There exists a significant relationship between the cost of FOIA litigation to federal agencies and the performance of FOIA implementation. There exists a significant relationship between the complexity of FOIA requests and the performance of FOIA implementation. This study also has important implication in South Korea, which has been under a sharp confrontation with North Korea for more than 50 years. As illustrated by the conflict between people's right to know and national security during the investigation of recent Sinking of the ROKS Cheonan, efforts should be made to prepare legal and institutional mechanism for freedom of information policy which can maintain a balance between conflicting values as well as efficient information disclosure in Korea.
