It has been highlighted that consumers tend to overspend when using cashless payments because the pain of paying associated with cashless payments is less pronounced than that of cash payments. However, excessive spending can also lead to unstable financial management for consumers. Therefore, it is important for consumers to understand their own behavioral characteristics associated with cashless payment and to deepen their knowledge of the characteristics of individual payment tendencies due to cashless payment usage in order to maintain healthy financial management while enjoying the convenience of cashless payment. Accordingly, this study examines the effects of self-control and the cashless payment experience on the willingness to pay using cashless payment. Although the results do not conclusively confirm the influence of self-control, the experience of using a credit card or debit card is found to increase the willingness to pay using such cashless means, even when there are no benefits such as reward points.

  This paper examines home economics-related content in social studies in elementary schools in Cambodia based on the revised curriculum and syllabus in 2018 by the Ministry of Education, Youth and Sport. As the social studies syllabus of Cambodian elementary schools progresses from Chapter 1 to Chapter 6, the content of education expands from the family, which is the closest community, to the larger community, the nation and society. In addition, as students progress from lower grades to higher grades, their specialization increases in the areas of history, geography, civic morality, and home economics. Next, in the home economics-related content of the social studies syllabus, each student is expected to acquire specific knowledge, skills, and attitudes regarding family and home life as they progress from lower grades to higher grades. When compared with Japan's elementary school guidance guidelines of home economics published in 2017 by the Ministry of Education, Culture, Sports, Science and Technology, there are shared descriptions in terms of family and home life.
