P-V곡선에 의한 음나무 묘목 상층엽의 수분특성을 측정하였다. 음나무 잎의 최대팽압시의 삼투포텐셜은 -1.44 MPa 이었고, 초기원형질분리점의 삼투포텐셜은 -1.84 MPa, 초기원형질분리점의 상대함수율은 78.2%였다. Water relations of Kalopanax pictus leaves obtained from the P-V curve. In the upper leaves of Kalopanax pictus seedlings, the original osmotic pressure at maximum turgor was -1.44 MPa, and the osmotic pressure at incipient plasmolysis point was -1.84 MPa, and the relative water content at incipient plasmolysis point was 78.2%.

The genus Hypoxylon is a member of the Xylariaceae that has brown to dark brown and phaseoliform single cell ascospores with a conspicuous full germ slit. Hypoxylon truncatum differs from H. annulatum, it has conspicuous perithecial mounds, dark brown stromatal surface, and absence of enriched ostiola disc. The isolate of Hypoxylon, collected from Mt. Deuk-yu in Korea, is compared with similar taxa and described. The isolation of H. truncatum is compared with similar taxa, H. annulatum, with a precise description in the SEM level in Korea.

The wide spread of wireless networks over the Internet makes it necessary to revaluate the performance of efficient protocols over wired and wireless networks. The different channel characteristics such as the bit error distribution and average bit error rate cause the performance of network protocols to be varied. To faithfully represent the wireless channel behaviors in simulation, various wireless channel models have been proposed. In this paper, we evaluate the faithfulness of four representative channel models by two metrics such as bit error rate and packet loss rate comparing to real sensor networks. We, furthermore, estimate the effect of the channel model precision to higher layer's protocols such as the link layer's FEC (Forward Error Correction) and TCP protocol. Our experiments showed that the average bit error rate in simulations was different by 30% maximally than that measured over real sensor networks. This bit rate gap, finally, leads to the different performance prediction of FEC and TCP by 30% and 20% respectively comparing to the real measurements.
