Storycrafting is a creative educational technique in Finland. Since 2011, storytelling approach of mathematics textbooks in South Korea can be regarded as opportunities for interesting learning of mathematics as well as its improper application to mathematics lessons. We need to revise and improve the storytelling method. The purpose of this study is to make a storycrafting program that encourages students to make mathematical stories for themselves and to analyze the effect of the storycrafting program on mathematical creativity and communication. To do so, we developed a storycrafting program of mathematics for sixth graders, which is composed of 33 lessons. And we applied them to one sixth class as experimental group. Through pre-test and post-test, their mathematical creativity and communication were tested. Based on the result of t-test, we can verify the statistical meaningful effect of the storycrafting program. This study contains some conclusions and suggestions.

Recently, smart wearable devices for monitoring health status have been utilized as interest in health care has increased. In this paper, we developed a fatigue measurement system that works with smart wearable devices. Unlike physical fatigue that is restored when you take enough rest, mental fatigue can decrease the efficiency or concentration of work, so you can monitor your mental health status through measurements. This system provides the function to transmit the measured data from the smart wearable device to the smartphone and to calculate the mental fatigue. A fatigue index was developed to measure fatigue and expressed as a number from 1 to 5. In addition, the results of the fatigue calculation and the survey were compared with the results of the independent sample t-test. Therefore, this system will be used to help users manage their health efficiently.

The purpose of this study is to investigate the relationship between self-control, value consumption, and subjective happiness of high school students. In this study, self-control is the students' ability to control their thoughts and emotions and value consumption is the psychological mechanism of their consumer behavior. To conduct this study, 400 high school students were surveyed. Independent sample t-tests showed statistical significance in the results that are discussed below. First, subjective happiness among the participants varied according to their self-control levels. We observed that the higher their level of self-control was, the higher their subjective happiness was also likely to be. Second, there was a significant difference in subjective happiness based on the value consumption level of high school students. We observed that the higher their value consumption level was, the higher their subjective happiness also was.

To derive implication for marketing strategy for Korean cosmetic products in China, an analysis was conducted on the difference in quality perception and purchase behavior between two groups of Chinese women classified by their awareness of Korean Wave. Analytical methods including k-means clustering method, independent samples t-test, factor analysis were applied on the survey results of Chinese women residing in Guangzhou city. The positive impact of Korean Wave on quality perception and brand image is much stronger for higher awareness group, compared against for lower awareness group, that leads to higher product satisfaction and willingness to recommend purchases. Thus, marketing strategies need to be adjusted based on the difference in customers awareness of Korean Wave. However, the low price is the primary inducement for purchases for both groups, increased efforts to enhance brand image and product quality as premium products is strongly required, together with the utilization of Koran Wave.

Since realtime search keywords of portal sites are arranged in descending order by instant increasing rates of search numbers, they easily show issues increasing in interests for a short time. But they have the limits extracted different results by portal sites and not shown issues by a period. Thus, to find key issues from the whole realtime search keywords for certain period, and to show results of summarizing them and analyzing differences, is significant in providing the basis of understanding issues more practically and in maintaining consistency of them. This paper analyzes differences of week key issues extracted from week analysis of realtime search keywords provided by two typical portal sites. The results of experiments show that the portal group means of realtime search keywords by the independent t-test and the survival functions of realtime search keywords by the survival analysis are statistically significant differences.
