The wild silkmoth Antheraea yamamai Guérin-Méneville, 1861 (Lepidoptera: Saturniidae) is an important producer of silk that is superior to the silk produced by traditional domesticated silkworm. In this study, we sequenced the complete mitochondrial genome (mitogenome) of An. yamamai collected from Jeju Island, which is the southernmost island approximately 100 km offshore southward from the Korean Peninsula. Determining this sequence will be necessary for tracing the biogeographic history of the species and developing molecular markers for identifying the origin of commercial products. Comparison of the sequence divergence among two available and the current mitogenomes revealed a low but substantial number of substitutions, totaling 23 nucleotides in the whole genome. CytB and ND5 showed the highest variability with five and four variations, respectively, suggesting that these regions will be prior regions to target for subsequent biogeographic and diagnosis study. Phylogenetic reconstruction based on all available sequences of Saturniidae showed that An. yamamai is a sister to the congeneric species An. pernyi, corroborating that Antheraea is a highly supported monophyletic group. The tribe Saturniini was clearly non-monophyletic and interrupted by Attacini and Bunaeini.

A quartz crystal microbalance (QCM) sensor system for the detection of odorants, especially environmental pollutant, has been constructed by depositing various phospholipids, activated carbon and lead compound pigment onto the surface of the QCM. The characteristics of a QCM operating at 9 MHz deposited with phosphatidyl- choline were analysed. An explanation is given for different odorant affinities based on the monolayer properties of phospholipids. The identification of odorants is discussed in terms of a comparison of their normalized resonant frequency shift patterns and relative response intensities calculated from the response areas. Applying the lead compound pigment coated QCM, it was possible to detect sulfur compound specifically. Using a number of different lipid-coated QCMs, odorants could be identified by comparing the response patterns.

Fe-28%Al($Fe_3Al$)과 Fe-28%Al-4%Cr($Fe_3Al-4Cr$) 금속간화합물을 대기중 1073, 1273, 1473k의 온도에서 최고 17일까지 장시간 산화시켰다. $Fe_3Al-4Cr$의 산화저항은 근본적으로 $Fe_3Al$과 거의 비슷하거나, 약간 우수하였다. $Fe_3Al$ 위에 형성된 산화물은 거의 순수한 ${\alpha}-AL_2O_3$로만 구성되어 있었으며, $Fe_3Al-4Cr$ 위에 형성된 산화물은 약간의 Fe와 Cr 이온이 고용된 ${\alpha}-AL_2O_3$로 구성되어 있었다. 외부산화막을 형성하기 위해 모재원소의 외부확산에 의해 산화물-모재 계면에는 Kirkendall 기공이 존재하였다. $Fe_3Al(-4Cr)$ 표면에 형성된 산화막은 1273k가지는 비교적 얇고 치밀하였으나, 1473k에서 산화막의 박리와 함께 상대적으로 큰 무게증가가 발생하였다. Intermetallics of Fe-28%Al($Fe_3Al$) and Fe-28%Al-4%Cr($Fe_3Al-4Cr$) were oxidized at 1073, 1273 and 1473k in air for up to 17 days. The oxidation resistance of$Fe_3Al-4Cr$ was basically similar to or better than that of $Fe_3Al$. The oxide scales formed on $Fe_3Al$ consisted essentially of pure ${\alpha}-AL_2O_3$, while those formed on $Fe_3Al-4Cr$ consisted of ${\alpha}-AL_2O_3$ having dissolved iron and chromium ions. The preferential outward diffusion of substrate elements to form the outer oxide layer led to the formation of Kirkendall voids at the oxide-matrix interface. The scales formed on $Fe_3Al(-4Cr)$ were thin and dense up to 1273K, but they spalled easily at 1473K, accompanied by more weight gains.
