The general learning method aims at conveying knowledge by conveying the contents of the learning set to numerous of learners. However, such a method is difficult to induce the interest of the learner, and the unilateral delivery method has a disadvantage in that the concentration of the learner can be lowered and the overall academic achievement can be lowered. In order to solve this problem, the gay learning method which induces the interest of the students themselves is studied, and the gay learning game which combines the education and the game can influence the learning by inducing the interest of the student. In this paper, we propose a method to prevent the forgery and falsification of the blockchain, which has been widely discussed by the 4th Industrial Revolution, as a card game, And suggests ways to contribute to the development of the process.

Through the 4th Industrial Revolution, various digital equipments are being distributed, and accordingly, the importance of data processing is increasing. As data processing has a great effect on the reliability of equipment, its importance is increasing, and various studies are being conducted. In this paper, we propose an algorithm to remove AWGN in consideration of the noise in the image. The proposed algorithm is used in the filtering process by inferring the standard deviation of the image noise. The noise is removed by dividing the filter for the high frequency component and the filter for the low frequency component compared with the standard deviation of the filtering mask. The proposed algorithm is simulated with the existing methods for evaluation and compared and analyzed by difference image, PSNR and profile. The proposed algorithm minimizes the effect of noise and preserves the important characteristics of the image and shows the performance of efficient noise removal.

In the modern society, the use of digital equipment is increasing along with the 4th industrial revolution, and the importance of image and signal processing is increasing. At the same time, research on noise reduction is being actively conducted. In this paper, we propose a switching filter algorithm for random-valued impulse noise cancellation. The proposed algorithm obtains the threshold value by determining the noise level present in the image, and threshold value is compared with the difference between the input pixel value and the reference value, and is used in the weight switching process of the filter. The final output of the filter is estimated by applying a pixel weight and a modified weight median filter according to the switching, and obtains a final output by comparing the estimated value with the input pixel value. To evaluate the performance of the proposed algorithm, we compared it with the existing methods using simulation and PSNR.
