genome size estimation of callipogon relictus Semenov coleoptera cerambycidae an endangered species and a korea natural monument
Insects, 2021Co-Authors: Soyeong Jin, Jongok Lim, Cheolhak Kim, Namjoon Cho, Seunggyu Lee, Sangil Kim, Jongseok Park, Keekwang Kim, Chungoo Park, Sungjin ChoAbstract:We estimated the genome size of a relict longhorn beetle, Callipogon relictus Semenov (Cerambycidae: Prioninae)-the Korean natural monument no. 218 and a Class I endangered species-using a combination of flow cytometry and k-mer analysis. The two independent methods enabled accurate estimation of the genome size in Cerambycidae for the first time. The genome size of C. relictus was 1.8 ± 0.2 Gb, representing one of the largest cerambycid genomes studied to date. An accurate estimation of genome size of a critically endangered longhorned beetle is a major milestone in our understanding and characterization of the C. relictus genome. Ultimately, the findings provide useful insight into insect genomics and genome size evolution, particularly among beetles.

Survey research on the habitation and biological information of Callipogon relictus Semenov in Gwangneung forest, Korea and Ussurisky nature reserve, Russia (Coleoptera, Cerambycidae, Prioninae)
'Pensoft Publishers', 2018Co-Authors: Seunggyu Lee, Cheolhak Kim, Bongwoo Lee, Alexander V Kuprin, Jung-hoon Kang, Jongok LimAbstract:An investigation on the habitation of Callipogon relictus Semenov, 1899 in Gwangneung forest was carried out, where the Korea National Arboretum is located. In an investigation spanning the last eleven years (2007–2017), 22 emergence holes, nine pupal chambers, six adults, and two larvae of C. relictus were identified. In this study, biological information about habitation of C. relictus is provided by comparing and combining the results of this investigation with a survey conducted in Ussurisky Nature Reserve, Russia, in 2015. The distribution is also reviewed to include the Korean Peninsula and a new location of South Korea is added to the distribution for C. relictus

molecular identification and larval description of callipogon relictus Semenov coleoptera cerambycidae a natural monument of south korea
Journal of Asia-pacific Entomology, 2013Co-Authors: Jongok Lim, Minyoung Kim, Ilkwon Kim, Sunghoon Jung, Jongsu Lim, Shinyoung Park, Kyungmi Kim, Cheolhak Kim, Bongkyu Byun, Bongwoo LeeAbstract:Abstract An unknown larva of enormous size was found from Carpinus laxiflora in the Gwangneung forest and identified by using a barcode gene. It was a larva of Callipogon relictus Semenov, a natural monument of Korea, at an undetermined instar. Based on the result, we provide the larval morphological description of this particular instar, with the illustrations and biometric measurement data of diagnostic characters.

Self-accelerating decomposition temperature (SADT) calculation of methyl ethyl ketone peroxide using an adiabatic calorimeter and model
Journal of Thermal Analysis and Calorimetry, 2008Co-Authors: W. H. Lin, G. Y. Shiu, Shyan-shu ShiehAbstract:The highly reactive and unstable exothermal features of methyl ethyl ketone peroxide (MEKPO) have led to a large number of thermal explosions and runaway reaction accidents in the manufacturing process. To evaluate the self-accelerating decomposition temperature (SADT) of MEKPO in various storage vessels, we used differential scanning calorimetry (DSC) and vent sizing package 2 (VSP2). The thermokinetic parameters were, in turn, used to calculate the SADT from theoretical equations based on the Semenov model.

prediction of the self accelerating decomposition temperature sadt for liquid organic peroxides from differential scanning calorimetry dsc measurements
Journal of Hazardous Materials, 2005Co-Authors: Marcus Malow, Klaus Dieter WehrstedtAbstract:We present a prediction (estimation, calculation, screening) method for the estimation of the self-accelerating decomposition temperature (SADT) for liquid organic peroxides from differential scanning calorimetry (DSC) measurements based on the concepts of thermal explosion theory originally introduced by Semonov which are adopted to our problem assuming nth-order reaction kinetics. For the peroxides under investigation, we demonstrate good agreement with the experimental SADT. This method can be used as a quick and easy applicable method for the estimation of the critical temperatures.
