Eumenis autonoe belonging to a lepidopteran family Nymphalidae (superfamily Papilionoidea) is an endangered species in Korea. Historically, the species was distributed in Europe and Asian region including a wide region in Korean peninsula. However, in Korean peninsula, the species is found only in two isolate dregions: South in a remote island Jeju, where altitude is higher than1, 400 meter on Halla Mt. and North in far northern Korean peninsula around Mt. Bekdu. In this study, we report the complete mitochondrial genome of the endangered E. autonoe collected from Mt. Halla. The 15,489-bp long E. autonoe genome has a typical gene content found in animal mitochondrial genomes and contains the gene arrangement identical to all other sequenced lepidopteran insects, which differs from the most common type found in insects, as the result of the movement of tRNAMet to a position 5’-upstream of tRNAIle. As seen in many other lepidopteran insects, no typical ATN codon for COI gene is available. Thus, we tentatively designated the CGA (arginine) found at the beginning of the COI gene, as has been suggested for lepidopteran COI starter. The intergenic spacer sequence located between tRNASer (UCN) and ND1 of E. autonoe mitogenome also contains the ATACTAA motif which is conserved in all sequenced lepidopteran species. The 678-bp long A+T-rich region, which is longest in sequenced lepidopteran insects contains ten identical tandem repeats composed of 27 bp plus one 13-bp long identical incomplete final repeat. Such repeat sequence is rare in the lepidopteran mitogenomes known so far. The E. autonoe A+T-rich region also contains a poly-T stretch located at the end of the region as 19 bp and also contains the downstream conserved motif ATAGA that were previously suggested to serve as a structural signal for minor-strand mtDNA replication. Phylogenetic analysis using the concatenated 13 amino acid sequences of PCGs among available six lepidopteran superfamilies (Tortricoidea, Pyraloidea, Papilionoidea, Bombycoidea, Geometroidea, and Noctuoidea) rooted with three dipteran species with BI and ML analyses supported the following topology: ((((Bombycoidea + Geometroidea +Noctuoidea) + Papilionoidea) + Pyraloidea) + Tortricoidea). Within Papilionoidea, a closer relationship between Lycaenidae and Pieridae, excluding Nymphalidae was observed. Further fruitful information will be available after more analysis is done.

The complete nucleotide sequences of the mitochondrial genome (mitogenome) from the white-spotted flower chafer, Protaetia brevitarsis (Coleoptera: Cetoniidae) was determined. The 20,319-bp long circular genome is the longest among the completely sequenced arthropods. This extraordinary length of the genome stemmed from 5,654-bp long A+T-rich region composed of twenty-eight 117-bp tandem repeats, seven 82-bp tandem repeats, and each two 19-bp and 38-bp tandem repeats. The P. brevitarsis contains a typical gene complement, order, and arrangement identical to most common type found in insects. The P. brevitarsis COI gene does not have typical ATN codon. Thus, we also designated it as AAC (asparagine), which is found in the start context of all sequenced Polyphaga within Coleoptera. All tRNAs showed stable canonical clover-leaf structure of other mt tRNAs, except for tRNASer (AGN), DHU arm of which could not form stable stem-loop structure. The 5bp-long motif sequence (TAGTA) that has been suggested to be the possible binding site for the transcription termination peptide for the major-strand also was found betweent RNASer (UCN) and ND1, as have been detected in all sequenced coleopteran insects.

The 15,389-bp long complete mitogenome of the endangered red-spotted apollo butterfly, Parnassius bremeri (Lepidoptera: Papilionidae) was determined. This genome has a gene arrangement identical to those of all other sequenced lepidopteran insects, which have the gene order of tRNAMet, tRNAIle, and tRNAGln at the beginning. Due to the uncertainty the start codon for COI gene in insect has been discussed extensively. We propose the CGA sequence as the start codon for COI gene in lepidopteran insects, based on complete mitogenome sequences of lepidopteran insects including our P. bremerii and additional sequences of the COI start region from a diverse taxonomic range of lepidopteran species (a total of 51 species belonging to 15 families). As has been suggested in other sequenced lepidopteran insects the 18 bp-long poly-T stretch and the downstream conserved motif ATAGA that were previously suggested to serve as a structural signal for minor-strand mtDNA replication also was found at the 3’-end region of the P. bremerii A+T-rich region. In an extensive search to find out tRNA-like structure in the A+T-rich region, each one tRNATrp-like sequence and tRNALeu (UUR)-like sequence were found in the P. bremeri A+T-rich region, and most of other sequenced lepidopteran insects were shown to have tRNA-like structure within the A+T-rich region, thereby indicating that such feature is frequent in the lepidopteran A+T-rich region. Phylogenetic analysis using the concatenated 13 amino acid sequences and nucleotide sequences of PCGs of the four macrolepidopteran suferfamilies together with Tortricoidea and Pyraloidea well recovered a monophyly of Papilionoidea and a monophyly of Bombycoidea. However, Geometroidea and Noctuoidea were unexpectedly clustered as one group and placed this group to the sister group to Bombycoidea, instead of Papilionoidea in most analyses.

The 15,338-bp long complete mitochondrial genome (mitogenome) of the Japanese oak silkmoth, Antheraeayamamai (Lepidoptera: Saturniidae) was determined. This genome has a gene arrangement identical to those of all other sequenced lepidopteran insects, but differs from the most common type, as the result of the movement of tRNAMet to a position 5’-upstream of tRNAIle. No typical start codon of the A. yamamai COI gene is available. Instead, a tetranucleotide, TTAG, which is found at the beginning context of all sequenced lepidopteran insects was tentatively designated as the start codon for A. yamamai COI gene. Three of the 13 protein-coding genes (PCGs) harbor the incomplete termination codon, T or TA. All tRNAs formed stable stem-and-loop structures, with the exception of tRNASer(AGN), the DHU arm of which formed a simple loop as has been observed in many other metazoan mt tRNASer(AGN). The 334-bp long A+T-rich region is noteworthy in that it harbors tRNA-likestructures, as has also been seen in the A+T-rich regions of other insect mitogenomes. Phylogenetic analyses of the available species of Bombycoidea, Pyraloidea, and Tortricidea bolstered the current morphology-based hypothesis that Bombycoidea and Pyraloidea are monophyletic (Obtectomera). As has been previously suggested, Bombycidae (Bombyxmori and B.mandarina) and Saturniidae (A.yamamai and Caligula boisduvalii) formed a reciprocal monophyletic group.

We determined the complete mitochondrial genome of the yellow-spotted long horned beetle, Psacothea hilaris (Coleoptera: Cerambycidae) that is an endangered insect species in Korea. The genome was sequenced from four overlapping fragments: two short fragments and two long fragments. The 15,857-bp long P. hilaris mitochondrial genome has the gene content typical of animal mitochondrial genome: 13 protein-coding genes, 22 tRNA genes, 2 ribosomal genes, and one non-coding A+T-rich region. The gene arrangement of the molecule is identical to the most common type found among insect mitochondrial gene arrangement that is regarded as ancestral for insects. Like several other coleopteran species the P. hilaris COI gene has typical mitochondrial start codon ATT. The 1,190-bp long A+T-rich region contains 57-bp long seven identical repeat sequences and at least seven stem-and-loop structures, composed of stems with perfect matches and loops with variable size. All P. hilaris tRNAs can be folded into the typical clover-leaf structure, with the exception of tRNASer(AGN), the dihydrouridine (DHU) arm of which forms a simple loop. After more genomic and phylogenetic analyses are performed, further detailed information will be available.

In this study, we determined the complete mitochondrial genome of the jewel beetle, Chrysochroa fulgidissima (Coleoptera: Buprestidae), from four overlapping fragments. The 15,592-bp long C. fulgidissima mitogenome exhibits a gene arrangement and content identical to the most common type in insects. The start codon of the C. fulgidissima COI gene is unusual, in that no typical ATN codon is available. The 875-bp A+T-rich region is the shortest among the coleopteran mitogenomes that have thus far been sequenced in their entirety. The most unusual feature of the genome is the presence of three tRNA-like sequences within the A+T-rich region: two tRNALeu(UUR)-like sequences and one tRNAAsnlike sequence. These sequence stretches evidence the proper anticodon sequence and the potential to form secondary structures, but also harbor many mismatches in the stems. Phylogenetic analysis using a concatenation of 13 amino acid sequences of protein-coding genes among the available sequenced species of coleopteran superfamilies (Buprestoidea and Elateroidea belonging to the infraorder Elateriformnia, and Chrysomeloidea and Tenebrioroidea belonging to the infraorder Cucujoiformia) by Bayesian inference, maximum-parsimony analyses, and maximum-likelihood analysis unexpectedly revealed a lack of support for monophyletic Elateriformia.

The 15,389-bp long complete mitochondrial genome (mitogenome) of the redspotted apollo butterfly, Parnassius bremeri (Lepidoptera: Papilionidae) was determined. This genome has a gene arrangement identical to those of all other sequenced lepidopteran insects, but differs from the most common type, as the result of the movement of tRNAMet to a position 5’-upstream of tRNAIle. No typical start codon of the P. bremeri COI gene is available. Instead, a tetranucleotide, TTAG, which is found at the beginning context of all sequenced lepidopteran insects was tentatively designated as the start codon for P. bremeri COI gene. All protein-coding genes (PCGs), but COII (T) have complete termination codon TAA or TAG. One of the most unusual feature of the P. bremeri mitochondrial genome is the presence of two tRNA-like structures, such as the tRNATrp-like sequence and tRNALeu (UUR)-like sequence with proper anticodon and clover-leaf structures in the 514-bp long A+T-rich region. Furthermore, the A+T-rich region possesses three sequences that have the potential to form stem-and-loop structures, flanked by the conserved sequences, "TA(A)TA" at the 5’ end and "G(A)nT’ at the 3’ end. After more genomic and phylogenetic analyses are performed, further detailed information will be available.

The completely sequenced mitochondrial genome of the brown marmorated stink bug, Halyomorpha halys, is a circular molecule of 16,518 bp with a total A+T content of 76.4%. Nucleotide composition and codon usage of this genome are near the means observed in other 12 hemipteran mitochondrial genomes; however, the initiation codon for CO1 gene appears to be TTG, dissimilar to what has been seen in the 12 mitochondrial genomes. In this genome, the A+T rich region between srRNA and tRNAIle gene includes two extensive repeat regions, in which each region includes 4 and 12 tandem repeats of a 73 bp sequence, respectively. The gene content, order, and structure of the H. halys mitochondrial genome are consistent with that of Triatoma dimidiata, belong to the same suborder Heteroptera, but different from two suborders, Auchenorrhynca and Sternorrhyncha, including various gene rearrangements. Analyzing phylogenetic relationship and comparing gene order and content of the 13 hemipteran mitochondrial genomes of three suborders, Heteroptera, Auchenorrhynca, and Sternorrhyncha, supported the morphology-based current hypothesis that both Auchenorrhynca and Sternorrhyncha are a monophyletic group.

We determined the complete mitochondrial genome (mitogenome) of the Japanese Oak Silkmoth, Antheraea yamamai (Lepidoptera: Saturniidae) from two overlapping fragments and subsequent shotgun sequencing. The 15,601-bp long A. yamamai mitogenome contains gene arrangement and content identical to the most common arrangement found in lepidopteran insects. Most individual A. yamamai mitochondrial (mt) genes were well within the range found in the respective genes of other insects, except for small ribosomal RNA (1,037 bp). The 336-bp A+T-rich region is relatively smaller than that of other lepidopteran insects. The region is interesting in that it contains tRNA-like structures as found in the A+T-rich regions of other insect mitogenomes. The start codon of A. yamamai COI gene is unusual in that no typical one (ATN) is available. Three of the 13 protein-coding genes have incomplete termination codon T or TA. All tRNA formed stable stem-and-loop structure, except for tRNASer(AGN), the DHU arm of which formed a simple loop as seen in many other metazoan mt tRNASer(AGN).

We determined the complete mitogenome of the oriental mayfly, Ephemera orientalis (Ephemeroptera: Ephemeridae) and the dragonfly Davidius lunatus (Odonata: Gomphidae). The 16,463-bp long E. orientalis and the 15,912 bp long D. lunatus mitogenome contains gene arrangement and content identical to the most common type found in a diverse insect order. Most individual E. orientalis and D. lunatus mt genes were well within the size found in the respective genes of other insects. The initiation codon for the D. lunatus COI gene was typical as ATA, whereas no typical start codon was found in the start region of E. orientalis COI gene. The A+T-rich regions of both mitogenomes have a few unusual feature. The A+T-rich region of E. orientalis contains a tandem repeat composed of two identical copies of 55 bp long, whereas that of D. lunatus contains a tandem repeat composed of duplicated identical 261-bp copies and one partial copy of the repeat. Also, the A+T-rich region of E. orientalis contains a single sequence and that of D. lunatus contains nine sequences, along with the tandem triplicate sequences, that has the potential to form stem-and-loop structures, flanked by the conserved sequences, “TA(A)TA” at the 5’ end and “G(A)nT’ at the 3’ end. Furthermore, the A+T-rich region of D. lunatus contains two tRNA-like structures, tRNALeu(UUR)-like sequence and tRNATyr-like sequence that have proper anticodon TAA and clover-leaf structure that were previously found in the hymenopteran insects.

We determined the complete mitochondrial genome (mitogenome) of the jewel beetle, Chrysochroa fulgidissima (Coleoptera: Buprestidae) from two overlapping fragments and subsequent sub fragments. The 15,592-bp long C. fulgidissima mitogenome contains gene arrangement and content identical to the most common arrangement found in insects. Most individual C. fulgidissima mitochondrial (mt) genes were well within the range found in the respective genes of other insects. The 875-bp A+T-rich region is shortest among the coleopteran mitogenomes sequenced in their entirety. The region is interesting in that it contains several stem-and-loop structures and tRNA-like structure found in the A+T-rich regions of other insect mitogenomes. As seen in other insect motogenomes the start codon of C. fulgidissima COI gene also is unusual because no typical start codon is available. Three of the 13 protein-coding genes have incomplete termination codon T or TA. All tRNA formed stable stem-and-loop structure, except for tRNASer(AGN), the DHU arm of which formed a simple loop as seen in many other metazoan mt tRNASer(AGN).

In this study, the paint, which has very close relationship to the of indoor air quality, was examined for the air pollution leveling test, and using the various passive sampler, the test was evaluated on the regard of TWA(Time Weighted Average). This study is to examine how the air pollution levels differ between the regular paint that is used for public and the new developed environment friendly paint. The consecutive experiments were performed in the small chamber test to investigate the VOCs and formaldehyde, ammonia emissions and characteristics from paint which are commonly used as the complete material of building. In conclustion, the natural paint showed the highest emission of VOCs among the selected paints, and water paint showed the highest contents of ammonia. Formaldehyde showed N.D(Not Detected) in most of tests and found a small amount in vinyl paint however, it was not as bad as to fail the certify level of building materials. It is recommended to constantly develop the chamber system and it will be very much possible to be used for the estimation of indoor air pollutants from the various paints and other complete materials.

A three-dimensional (3-D) method of analysis is presented for determining the free vibration frequencies and mode shapes of solid paraboloidal and complete (that is, without a top opening) paraboloidal shells of revolution with variable wall thickness. Unlike conventional shell theories, which are mathematically two-dimensional (2-D), the present method is based upon the 3-D dynamic equations of elasticity. The ends of the shell may be free or may be subjected to any degree of constraint. Displacement components ur, uθ, and uz in the radial, circumferential, and axial directions, respectively, are taken to be sinusoidal in time, periodic in θ, and algebraic polynomials in the r and z directions. Potential (strain) and kinetic energies of the paraboloidal shells of revolution are formulated, and the Ritz method is used to solve the eigenvalue problem, thus yielding upper bound values of the frequencies by minimizing the frequencies. As the degree of the polynomials is increased, frequencies converge to the exact values. Convergence to four digit exactitude is demonstrated for the first five frequencies of the complete, shallow and deep paraboloidal shells of revolution with variable thickness. Numerical results are presented for a variety of paraboloidal shells having uniform or variable thickness, and being either shallow or deep. Frequencies for five solid paraboloids of different depth are also given. Comparisons are made between the frequencies from the present 3-D Ritz method and a 2-D thin shell theory.

Objectives: To develop normative data for normal young adults, to interpret patients’ CMDT score objectively and select the employees who require manual dexterity. Methods: Participants were sixty normal subjects (thirty males and thirty females) between ages of 19 and 26. Averaged performance duration of normal subjects on the CMDT was recorded and Pearson Correlation Coefficients between subtests of CMDT were analysed. Results: Women’s performance duration was shorter than that of men’s, but the percentile scores were different according to the percentile. Pearson Correlation Coefficients were significantly different between the subtests, but not in the results of comparing ‘displacing’ and ‘one hand turning and placing’. Conclusions: These data will assist occupational therapists and others to interpret patients’ CMDT scores objectively.
