Japan's economy made rapid and steady progress in the post-war half century and children grew by 2 cm per decade. Economic development in South Korea was some two decades behind Japan, due to the Korean War (1950-53). Teens in Korea were 2-3 cm shorter in height than their Japanese peers in the 1960-70s, caught-up with the latter in the early 1990s and then outgrew Japanese teens by 3 cm in the mid-2000s. They ceased, however, to grow any taller afterwards, whereas the national economy remained prosperous and per capita supply of animal-sourced foods, including milk increased appreciably.School boys in Korea were 1.5 cm greater than their Japanese peers in growth velocity from 1st graders in primary school to high school seniors in the early 2000s but began to fall persistently in velocity to be 2 cm below Japanese in the end of the 2010s.Analyzing Household Expenditure Surveys, 1990 to 2019, the authors were stunned to discover that Korean children started to turn away from vegetables in household consumption in the mid-1990s and ate as little as 10% of vegetables as the control group (people in their 50s) in the mid-2010s. Children in Japan started to steer away from fruit and vegetables in the end of the 1970s, when supply of per capita meat and milk was expanding. It is suspected that vegetables and fruit may be among essential nutrients for child height development.

Summary Many attempts to utilize ICT (Information and Communication Technology) tools have been made to promote active and interactive learning between teachers and students. A major area has been the introduction of education using clickers for dental students, and some reports indicated their effects. However, the introduction of mobile devices and software and their maintenance and management very costly. On the other hand, almost allundergraduate students of Matsumoto Dental University have a smartphone, and can connect to the Internet in the lecture room. Therefore, we conducted online exercises to pre- pare for the National Board Dental Examination using students' smartphones and the online real–time voting service"Mentimeter" at the lecture of Operative Dentistry for 6th–year dental students of Matsumoto Dental University, in the school year of 2019. We also conducted some anonymous online questionnaires using Mentimeter. Thirty percent of the participating students answered that they were not good at conservation and restoration studies. Although 97% of students answered that the test questions conducted in the exercise using Mentimeter were difficult, 92% of the students answered that the exercise was effective in deepening their knowledge of Operative Dentistry. The results of the questionnaires suggested the effectiveness of the interactive lecture using Mentimeter in order to deepen and retain knowledge of Operative Dentistry.
