So far, the use of superconducting magnets has been limited to chemical analysis and medical inspection. To develop a new use, we have tried to apply common MRI devices as nondestructive sugar content detector of watermelon. To estimate the sugar content, a new technique using multiple regression analysis of two NMR relaxation times was developed. It was found that the coefficient of multiple regression at the center of the watermelon exceeded 0.9 and the standard error of prediction was around 0.5, and that the over-ripened part of flesh called ‘nieka’ in watermelon could be distinguished because its T2 was much longer than that of the oridinary part. An evaluation rate of sugar content could be below 6s per watermelon. It is concluded that multiple analysis of T1 and T2 on intact watermelon can be applied as a non-invasive, nondestructive indicator of sugar content.

Accelerating M&A of worldwide giant firms in 2015 evokes Galbraithian hypothesis. Galbraith (1952) has asserted that only a few giant firms can conduct technological innovation required in the modern world to develop new products and processes. This view has been challenged and extensively tested since the 1960s. In general, a popular outlook on the advantage of firm size in conducting R&D has been transferred to the smaller, younger and fast-growing firms, which can play an important role for an invention. As noted in Cohen (2010), however, the question of the relationship between firm size and R&D efficiency remains open. Using data on worldwide Top1000 investors in selected R&D intensive industries from 2005-2014 EU Industrial R&D Investment SCOREBOARD, the relationship among sales, R&D expenditures and profitability is more closely examined. The central direction toward Galbraithian hypothesis can be identified with both nonlinear regression analysis and time-series analysis. More significantly, nations with increasing R&D intensity tend to improve the profitability.
