I tried to make a comparison between two issues of Mases. One is issue of June, 1914, and the other one is issue of June, 1915. One of the most salient characteristics in frequency of words was the use of the word 'women' and 'men'. The frequent words in Masses of 1914 showed both 'men' and 'women' in a similar ratio, but in case of 1915 issue, I could only find the word men occurred frequently. I want to ask about the reason for this difference of frequency in words of men and women, because this would implicate the relationship between class and women. In addition, in the issue of 1914, I could find some words related to the nationality such as Mexico, and American, but in the issue of 1915, I could not find such words. It seems important theme to me, because this can be an evidence of the fact that the magazine also tries to encompass different social movements in different countries. Both of two issues seem to focus on the word ‘masses’ and ‘new’. From this idea, I could find the fact that the magazines seem to focus on the movement of masses and making a new change in the society and I want to study more about this.
