Application of LED Headlamps in S. Korea

Secular Changes in Relative Height of Children in Japan, South Korea and Taiwan: Is “Genetics” the Key Determinant?

“…Copy@ Hiroshi Mori * 6 The author obtained the data pertaining to mean height of Taiwanese school children for the years from to 2016, only for the age ranges from 6 to 15 years [33]. * 7 In the ordinary A/P/C model, the impacts of period, say, changes in prices, incomes, for example, are assumed to be uniform over the different age and cohort groups in the same period.…”

“…Are these differences in body height between the two countries to be attributed, primarily, to differences in genetics? Intuitively, the answer should be "yes, very likely" [6]. As mentioned above, Koreans were nearly 3 cm shorter than Taiwanese in 1890-1930.…”

Cyano Acrylate Polymers in Medical Applications

“…The polymer capsule realizes compatibility of water-solution, drug and oil-solution, provides sustained release function. Thus, these compositions are used for ultrasonic contract and molcular imaging [25].…”

Design with White Light-Emitting Diodes for an Automotive Low-Beam Projector Headlamp

“…As a new type of light source, LEDs became available for application as automotive headlamps along with the rapid progress in luminous efficiency and heat dissipation technology characteristic of white LEDs. Although the price of LEDs is high, there are many advantages, such as longer lifetime, lower power consumption, short response time, and no mercury pollution, (1) as compared with conventional light sources. Since the luminescence characteristics of LEDs are different from those of conventional light sources, optical systems utilizing LEDs need to be redesigned.…”
