This paper embodies the rating recognition system of broadcast program which can automatically acknowledge the broadcast pictures indicating the harmfulness rating, so prevent children from watching TV. This experiment was progressed as the course of extracting featured patterns (standard number patterns) and the proper patterns owned only by the concerned numbers from the numbers of standard font used by broadcasters, and comparing these patterns with input pictures and arranging them. The recognition rate of x-rating was remarkably high as a result of this experiment.

Recently, Game Rating Board has been established. It is to follow worldwide trend in building up publicity, autonomy and professionalism under the framework to assure freedom of expression. This article analyzed major nation's game rating system, and showed some points to need improvement which are to have more detailed classification in game rating, to modify contents descriptor, to appoint committee members with expertise on game, to revise articles to be capable of misuse, and to become a nongovernmental organization.

The aim of the study was to explore the effects of parental media mediation types on adolescents' perception of the usefulness of the broadcasting rating system. A total of 520 middle school students participated in the survey. Results showed a higher utility of 'autonomy-supportive restriction' strategy by the parents led to more positive perception of the usefulness of the rating system. This study argues that parents need to pursue a mediation strategy in which a rationale for prohibiting media contents use should be provided and in which the perspective of the adolescent is taken seriously.

The circulation of unwholesome information such as obscene and violent information is gradually increasing based on the rapid expansion of information communications infrastructure. Those kinds of information are harmful to the adolescents and even cause social problems so that active countermeasure is requited. In order to cope with the spread of unwholesome information, appropriate regulating methods are absolutely in need by establishing or revising information communications-related laws. In this paper, we had analyzed domestic and foreign programs with existing harmful information blocking method, and then designed and implemented a selective blocking program based on Platform for Internet Contents Selection(PICS) by using selective blocking technology based on Internet contents rating system. We also proposed a compromised rating system blocking method that consists of selective filtering function by age and the popular blocking list. The proposed system has advantages in that there would be no increase in network load resulting from blocking list update and inquiry, it is possible to perform active selective filtering considering user's age, and it may introduce self-imposed rating.

While the United States and Japan have non-government film rating system, Korea and France are still maintaining governmental control process. But the restrict showing rate in Korea does possibly violate the Constitution with no theatre for the movies of that rate right now. No other visual media including broadcasting have any outer classification process before their showing. So we need to improve our system by replacing it with non-governmental system. To establish independent non-government rating system, first of all, the major companies of film industry should get together to set up Korean Classification and Rating Association, to support the Film Rating Board. The most important thing is that the board operates independently. Government can support art cinemas financially with rating fee. Juvenile protection groups have to keep watch on the process of the board going fairly as well. The chief obstacle for non-governmental rating system is the fact that major companies don't want to get it. But continuing efforts to find any rational way is worthy enough.

Rating system, which generated by struggling and negotiating of many social groups, helps us to anyalyze plenty of social factors. With this point of view this article attempts to examine the game rating system of Iran, that started in 2009. At the beginning, the nubmber and ratio of prohibited games were very high. Most prohibited games have contents of violence with religious distortion or women's nudity. But recently the case of prohibition is not seen and the ratio of age rate is changed to that of other countries. The system and operation of ESRA is influenced by multiple factors like the willingness to support game industry of government, the understanding of industrial value, the acknowledgement of cultural effect of game and etc.

This article explores on the deploying of game rating system in the context of whole game governance. Rating system is critical apparatus of game policy because it works as a kind of counterweight between different actors. We analyse to apply the three form of governmentality by Faucault. Rating system can be commonly considered as security mechanism. Korean rating system has hoped to be so but its effect was not actually. We should see why that system evolve to disciplinary mechanism, not toward security mechanism. Sound governance shows to be ensure all actors to participate its procedures practically, through constituting more rich discourse.

On the internet, the rating scores assigned by customers are considered as the preference information of themselves and thus, these can be used efficiently in the customer profile generation process of recommender system. However, since anyone is free to assign a score that has a biased rating, using this without any filtering can exhibit a reliability problem. In this study, we suggest the methodology that measures the reliability of rating scores and then applies them to the customer profile creation process. Unlikely to some related studies which measure the reliability on the user level, we measure the reliability on the individual rating score level. Experimental results show that prediction accuracy of recommender system can be enhanced when ratings with higher reliability are selectively used for the customer profile configuration.

This study explores multiple variables of an OTT service for discovering hidden relationship between rating and the other variables of each successful and failed content, respectively. In order to extract key variables that are strongly correlated to the rating across the contents, this work analyzes 170 Netflix original dramas and 419 movies. These contents are classified as success and failure by using the rating site IMDb, respectively. The correlation between the contents, which are classified via rating, and variables such as violence, lewdness and running time are analyzed to determine whether a certain variable appears or not in each successful and failure content. This study employs a regression analysis to discover correlations across the variables as a main analysis method. Since the correlation between independent variables should be low, check multicollinearity and select the variable. Cook's distance is used to detect and remove outliers. To improve the accuracy of the model, a variable selection based on AIC(Akaike Information Criterion) is performed. Finally, the basic assumptions of regression analysis are identified by residual diagnosis and Dubin Watson test. According to the whole analysis process, it is concluded that the more director awards exist and the less immatatable tend to be successful in movies. On the contrary, lower fear tend to be failure in movies. In case of dramas, there are close correlations between failure dramas and lower violence, higher fear, higher drugs.
