The development of recent science technology and computer application technology has brought many changes in our society The interest in using computers for foreign language education has been emphasized due to these continuing development in technology and social changes. Therefore, the role of the teachers has increased since the early 1990s. Today CMC is concerned with communication between two or more participants via a computer in foreign language education. This study suggests that the teacher's role is very critical in new foreign language education through CMC and this article recommends :The first thing is the roles of teachers such as teachers training, political concern,, financial supports, social and cultural aspects, teachers themselves, and positive CMC activity. The second is to develop the special programs for the English to make new studying circle through the Internet, and to support group study using foreign language. In conclusion, the teachers should guide their students in their studying English by using CMC which is supported by various groups in our society.

The purpose of this thesis is to analyze the authoring tools which can be used for the efficiency of English instruction. We have some steps for this analysis. The first one is to analyze the functions of English learning. The second one is to improve the software function for English learning through a comparative study between the Authorware 5.0 program and the PASS2000 1.0 program. The final one is to recommend directions for English learning in the framework of authoring tools. The first result of the comparative study is that the PASS2000 is more effective than the Authorware in English learning. The PASS2000 authoring tool has many advantages in authoring English education material. But this program will need to improve its functions by analysing the method of English learning in listening, speaking, reading, writing.

In an attempt to find bioactive natural products with an anti-inflammatory activity, we evaluated the effects of the methanol extract of Fomes fomentarius (MEFF) on in vivo anti-inflammatory and anti-nociceptive activities. MEFF (50, 100 mg/kg/d, p.o.) reduced acute paw edema induced by carrageenin in rats, and showed MEFF analgesic activity, as determined by an acetic acid-induced writhing test and a hot plate test in mice. To investigate the mechanism of the anti-inflammatory action of MEFF, we examined the effect of MEFF on lipopolysaccharide (LPS)-induced responses in murine macrophages cell line RAW 264.7. MEFF potently inhibited the production of nitric oxide (NO), prostaglandin E₂ (PGE₂), and tumor necrosis factor-α (TNF-α) in LPS-stimulated RAW 264.7 macrophages. Consistent with these observations, inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) levels were reduced by MEFF in a dose-dependent manner. Furthermore, MEFF suppressed nuclear factor-кB (NF-кB) activation in LPS-stimulated RAW 264.7 macrophages. These findings suggest that the anti-inflammatory and anti-nociceptive properties of the methanol extract of MEFF may result from the inhibition of iNOS and COX-2 expression through the down-regulation of NF-кB binding activity.
