This study aims at analyzing hypermedia interactivity in terms of learner control, self-regulation, and continuing motivation; at revealing what the most required learner ability is; at providing the ways of increasing the ability. The points of hypermedia interactivity are as follows ; First, hypermedia basically permits learner control even if they are restricted within the category of nodes and links made by the author. Second, hypermedia cannot fundamentally replace the learner's self-regulation ability even if they can partially assist it through establishing browser and inserting advice. Third, hypermedia can easily trigger learner's learning motivation through various forms of content expression such as graphic, animation as well as letters, learner's free selection and organization of content, and multi-screen presentation of content. Here the educational effect of hypermedia is influenced by the author's generating activity of nodes and links, and the learner's using activity. However, hypermedia have been made easy to use according to the learner's intention on the basis of vast information. Therefore, the educational effect of hypermedia being dependent on learner, the acquisition of metacognitive skill elevating the learner's using activity will be an important factor in enhancing the educational effect of hypermedia.

Body condition score (BCS) is a useful management tool for distinguishing differences in nutritional needs of cows in the herd. Although it is not always possible to quantify the nutrient content of the feed supplied to the donor cow, the nutritional status can be determined by the BCS. The objective of this study was to evaluate in vivo embryo production, return to estrous of donor and pregnancy rate of recipients following BCS in Hanwoo superovulation. Sixty nine Hanwoo donor cows were flushed on day 7 of estrus cycle with same FSH and artificial insemination by the same technicians. Embryos were recovered on 7 days after the third insemination by flushing the uterus with Embryo Collection Medium. The results obtained were as follows: No differences were observed in the efficiency of superovulation rates regardless of BCS (≤2.0, 2.5 to 3.0, and ≥3.5). The mean number of total embryos was each 5.20±0.86, 11.56±1.04, and 6.23±1.07. The mean number of transferable embryo from ≤2.0, 2.5 to 3.0, and ≥3.5 of BCS was 2.60±0.87, 7.94±0.89, and 4.75±1.32, respectively (p<0.05). Return to estrous regardless of donor BCS was no difference. The pregnancy rates of recipient were BCS ≤2.0 11.76%, 2.5 to 3.0 40.79%, and ≥3.5 11.11%, following transfer of fresh embryos produced in vivo, respectively. These results indicate that if the Hanwoo with BCS 2.5 to 3.3 are used for donor and recipient, the embryo production and the conception rate will be greater.
