As games have been used throughout the advertisement design in diverse ways, the paradigm of the internet advertising has also been changed. At the same time, there has been a growing tendency among companies to maximize the purpose of advertising by using game-like internet banner advertising, which provides internet-users with the information of the advertisements by exposing specific information, brands, characters, or image. In spite of the quantitative expansion of the game-like internet banner ads, according to a survey with regard to their click-through rate(CTR), the result indicates the CTR is less than 0.5%. Therefore, this study aims to examine what types of displaying elements of the game-like banner ads gaining in popularity can leave the users with a strong impression, and also to explore what types of displaying elements need to be highlighted for the users' active and aggressive access to internet banner advertisements. Currently advertised game-like banner ads on the internet web sites in different fields are selected. Then, they are analyzed by using seven categories. The findings are expected to lay out systematic and practical guidelines for the future production of game-like banner ads.

Due to the Covid-19 Pandemic, the world is facing the most serious crisis since the Great Depression, and is facing a new paradigm of the Untact era. Korea has also announced various policies and legal systems, including the 'Korean version of the New Deal', but it is conflicting between the use of information and the protection of information. In this paper, we derive thresholds by analyzing policies, statutes and technologies in the public cloud. Based on this, we propose to introduce the "Building a Nationwide Public Virtual Machine" as a key task to secure the next-generation national growth engine so that all citizens can use digital services in a secure and reliable environment with equal access to information. Through this, all citizens can use various digital new technology services only with low-priced and low-specification terminals, and by establishing a dedicated center for information protection, we want to respond to rapidly increasing security threats. It also points out that the domestic cloud-related legal system only emphasizes the use of information while overlooking the importance of security, and suggests the right direction for the legal system to move forward.

Today's public sector information is considered an important national asset that has social and economic value. Hence, developed countries are competitively promoting various policies to actively promote access to public sector information and the use of such information for private purposes. The Korean government is also boosting the Government 3.0 policy as a new governmental management paradigm that supports the creative economy. Despite these governmental efforts, since open public sector information is only classified from the supplier's perspective, it is difficult to have access to information for private application from the consumer's perspective and expand private applications because of the problems in identifying the information source. In this study, the concept of data from the user's perspective for the activation of private applications was defined by focusing on public sector information obtained by affiliated organizations of the Ministry of Science, ICT and Future Planning(MSIP). The new classification system was designed by analyzing the classification system of conventional open services of public sector information through investigation.
