This study investigated the use of the amplifier very in high school English textbooks and native corpora by comparing its frequency distributions and collocation patterns. The native corpora, used as the reference of the study, were COCA and BNC, with their built-in sub-corpora further grouped into spoken and written corpora. The High School English Textbook Corpus (HSETC) was compiled from a total of 53 high school textbooks, with the spoken corpus (HSETC-S) from the texts in listening and conversation and the written corpus (HSETC-W) from the reading passages. Analyses using AntConc3.4.4 revealed no prominent differences between HSETC and reference corpora in the frequency of the amplifier very, while the written corpus (HSETC-W) had more occurrences contrary to the native corpora. The combination patterns and their occurrences of HSETC were slightly different from those of COCA and BNC with the gap increased with the spoken corpus (HSETC-S). Pedagogical implications and suggestions are made on ELT materials development and teaching practices.

This study was carried out to compare the actual size(length and height) of ovaries, follicles and corpora lutea of Korean native cow with those on sonograms. We used 3 different probes(3.5 MHz abdominal probe, 6.5 MHz transvaginal probe and 5.0 MHz transrectal probe) and a calipher for measurements of ovaries, follicles and corpora lutea on sonograms and actual size. Under water immersion, 157 ovaries were scanned with 3 probes and measured in actual size and compared each other. The average height and width of ovaries of Korean native cows were 17.403.99 and 34.236.02mm, respectively. In comparison of height, length of ovaries and preovulation follicles, we found that image with a transvaginal probe was nearly the same as the actual size(p<0.01), but with an abdominal probe the image was appeared larger than the actual size. In measurement(diameter) of preovulation follicles the transvaginal probe was proven to be more accurate to the actual size than other probes and in corpus luteum measurement all probes were accurate. In the comparison of number of follicles by different size ranges, there was no statistical difference in the count of follicles over 10 mm in diameter between the transvaginal probe and naked eyes.
