Q: Passage: On an international level the German DIN 4512 system has been effectively superseded in the 1980s by ISO 6:1974, ISO 2240:1982, and ISO 5800:1979 where the same sensitivity is written in linear and logarithmic form as "ISO 100/21°" (now again with degree symbol). These ISO standards were subsequently adopted by DIN as well. Finally, the latest DIN 4512 revisions were replaced by corresponding ISO standards, DIN 4512-1:1993-05 by DIN ISO 6:1996-02 in September 2000, DIN 4512-4:1985-08 by DIN ISO 2240:1998-06 and DIN 4512-5:1990-11 by DIN ISO 5800:1998-06 both in July 2002.

Q: Passage: Some Samoans are spiritual and religious, and have subtly adapted the dominant religion of Christianity to 'fit in' with fa'a Samoa and vice versa. As such, ancient beliefs continue to co-exist side-by-side with Christianity, particularly in regard to the traditional customs and rituals of fa'a Samoa. The Samoan culture is centred around the principle of vāfealoa'i, the relationships between people. These relationships are based on respect, or fa'aaloalo. When Christianity was introduced in Samoa, most Samoan people converted. Currently 98% of the population identify themselves as Christian.
