This study is a leading research project to develop an automatic grade decision making algorithm of a 6-years-old fresh ginseng. For this work, we developed a Ginseng image acquiring instrument which can take 4-direction's images of a Ginseng at the same time and obtained 245 jingen images using the instrument. The 12 parameters were extracted for each image by a manual way. Lastly, 4 parameters were selected depending on a Ginseng grade classification criteria of KGC Ginseng research institute and a survey result which a distribution of averaging 12 parameters. A pattern recognition classifier was used as a support vector machine, designed to "k-class classifier" using the OpenCV library which is a open-source platform. We had been surveyed the algorithm performance(Correct Matching Ratio, False Acceptance Ratio, False Reject Ratio) when the training data number was controlled 10 to 20. The result of the correct matching ratio is 94% of the $1^{st}$ ginseng grade, 98% of the $2^{nd}$ ginseng grade, 90% of the $3^{rd}$ ginseng grade, overall, showed high recognition performance with all grades when the number of training data are 10.

This study aims to investigate the transition of the game rating system in Korea and to search for problems and improvement measures in the era of IARC game grade review. IARC(International Age Rating Coalition) is an International Classification Alliance, with 37 member organizations from 6 countries. In addition, IARC grants participating store-fronts autonomy to review game ratings. The method of deliberating games in Korea is proceeding with direct review by rating system and deliberation by IARC's own classification system. The problem of the rating system of the game is that the civilian becomes the subject, it relies on the questionnaire, and its side effects are caused by its own classification system. IARC guidelines can be developed to improve the game rating system, education on penalties and ratings for game developers, and management of participating front-stores. In conclusion, it may be dangerous to delegate rating authority to open market, and it is necessary to construct a discussion forum for ratings, including government and industry, game developers, users, and parents of under-age gamers. It is necessary to create a rating system for the game environment in Korea.
