This study was carried out to Investigate the biochemical characteristics, antibiotic susceptibility, serogroups and pili producibility test of enterotoxigenic Escherichia coli(ETEC) isolated from piglets with diarrhea in Kangwon province from March to October 1996. 1. Sixty eight E coli strains were isolated from 72 piglets with diarrhea and the biochemical and cultural reaction were compared with the classification criteria of Edwards and Ewing. 2. The serogroups of 26 isolates were classified as 08 : K87 6(8.8%), O20 : K1O1 4(5.9%), O141 : K85 4(5.9%), 09 : K103 : P987 3(4.4%), O45 : K 2(2.9%) 0139 : K82 2(2.9%), O64 : $K^{-}$2(2.9%), O149 : K91 1(1.5%), O157 : K88ac 1(1.5%) and O115 : $K^{-}$1(1.5%), respectively. 3. In antibiotic susceptibility test, the isolates showed high susceptible to Ak, Eno, Na, Gm, Am and Km, whereas resistance to Tc, Sm and Cf. 4. Sixty one strains(89.7%) of 68 I coli Isolates were resistant to one or more drugs. The isolates resistant to 2 and 3 or more drugs were 60.3% and 19.1%, respectively. Amog the 16 multiple resistant patterns, Sm Tc(11.5% ), Cf Sm Tc(11.5% ), Cf Cp Sm Su Tc(9.8% ) and Cf Cp Sm Su Tc(8.2%) patterns were frequently observed. 5. MRHA of guinea pig erythrocytes was detected in 9 out of 26 OK serotype and 9 out of 42 unidentified serotypes. MRHA titers of serotypes showed from 16 to 32 in O141 : K85 and no titers in O139 : K82. 6. By the GM1 ganglioside ELISA, $\beta$-, $\alpha$-, and $\gamma$-hemolysin producing strains was detected as 36, 6, and 5 from heat labile enterotoxin(LT) of 47 ETEC, respectively. The distribution of LT toxin from 112 isolates was showed $\beta$- hemolysin, 2 isolates $\alpha$-hemolysin and 3 isolates $\gamma$-hemol-ysin from 26 OK serotypes.

This experiment was carried out to find the effect of different organic farming types, the Duck - pasture plot, the Pond-snail pasture plot and control of the conventional culture plot farming on the yield and its components of paddy rice. The results obtained are summarized as follows. Plant height and Tillering were significantly increase in the Duck - pasture plot. Panicle number per hill, No. of grain per spike and 1,000grain weight were significantly increase in the conventional culture plot. Yield per 10a were 574.13^ at pond-snail pasture plot, 576.81kg at Duck-pasture plot and 579.04kg at conventional culture plot. From these results, it seems that the organic fanning are usefel and pasture of the Duck, Pond-snail for depression of the weed occurrence or increase of yield per 10a is effective as the environmental perservation farming.

This experiment were performed on rice dignity during 1998 at paddy field of Dong-a Univ., Pusan, Korea. Depression effect of weed occurrence by pasture of 2kg of the Ampullarius insularus per 10a was 80.4% at the 7th day after transplanting, 69.7% at the 14th day after transplanting pasture plot and 51.8% at the 21th day after transplanting. Depression effect of weed occurrence by pasture of 5kg of the Ampullarius insularus per 10a was 97.9% at the 7th day after transplanting, 79.2% at the 14th day after transplanting pasture plot and 64.1% at the 21th day after transplanting. Depression effect of weed occurrence by pasture of 8kg of the Ampulbrius insularus per 10a was 97.9% at the 7th day after transplanting, 87.1% at the 14th day after transplanting pasture plot and 71.4% at the 21th day after transplanting. Weeds ingestied by the Ampullarius insularus were in the order of perennial weed, annual weed.
