        The phylogenetic relationships of species and genera in the subfamily Nymphalinae from Myanmar were inferred using mtDNA sequence data from 608 bp of cytochrome oxidase subunit I (COI). A total of 20 species in 10 genera were sequenced and used to construct phylogenetic trees. The base composition of COI sequences was 38.1% T, 15.6% C, 31.6% A, 14.7% G, revealing strong AT bias (69.7%). The sequence distance of 20 species of Nymphalinae ranged from 1.5% to 15.5%. The transition of nucleotide substitution was more common than transversion. The transition between T and C were higher than transition between A and G, and the transversion between A and T was the highest amongst other types of transversion. The phylogenetic trees were constructed using the neighbor-joining (NJ) and maximum likelihood (ML) methods and showed almost identical topologies. The results indicated that the tribes Junoniini and Nymphalini (sensu Wahlberg et al., 2005) formed monophyletic groups but Kallimini was not monophyletic group. Rhinoplapa polynice formed sister group to Junoniini clade with moderate support in both trees. The relationship of species in Junoniini was ((Junonia + Yoma) + Hypolimnas) and the relationship in Nymphalini was (Symbrenthia + (Vanessa + (Kaniska + Polygonia))). The clustering results were almost identical to current morphological classification.

        This study was carried out to know some regional gene difference in carabid beetle, Coptolabrus jankowskii. There are eight subspecies in this species from Korea and it was too difficult to identify by morphological similarity. The mitochondrial ND5 (NADH dehydrogenase subunit 5) gene of Coptolabrus jankowskii from four regions of (Sangju, Daegu, Mt. Jumbong and Jeju island) was compared. The results showed the differences of the base sequence of total 57 sites and the amino acid variation of the 25 sites. The Neighbor-joining tree and Maximum parsimony tree were established based on sequence data of the ND5. In NJ tree, the Jeju area except Songdangri, and Mt. Jeombong region showed close relationship group. In the case of Maximum parsimony tree, the result divided to three separated group, the first connected group was Jeju Songdangri area and the other the Korean peninsula region except Mt. Jeombong. Others were Jeju area except Songdangri, and Mt. Jeombong region.

        Pansies butterflies belong to the genus Junonia are widely distributed throughout Myanmar and 6 species of Junonia have been reported in Myanmar. Molecular comparison of the cytochrome c oxidase subunit I (COI) nucleotide sequences among the species of Junonia was conducted. The nucleotides divergence of COI sequences between species were 2.9 to 7.9% and sequences identity was 92.5-97.7%. The phylogenetic trees were constructed by using Neighbour-joining (NJ) and Maximum likelihood (ML) methods. In both methods, phylogentic trees were showed identical and were revealed that all sequences of Junonia species from Myanmar were in the same cluster with those of the same species from other countries.

        The purpose of this study is to identify the level of masseter muscle tension according to the levels of restricted movement and pain in the temporomandibular joint(TMJ), thereby verifying the fact that excessive masseter muscle tension can be a cause for restricted movement and pain in the TMJ. The subjects of this study were 81 men and women in their 20s and 30s, who feel uncomfortable with their masticatory function on the preferred chewing side. The subjects were measured in terms of the range of motion (ROM) and deviation of the TMJ and the degree of pain in the affected region. The ROM and deviation of the TMJ were measured using the Global Posture System(GPS) after instructing each subject to open his/her mouth to the fullest and taking photos of the subject with a digital camera. The tension of the masseter muscle was measured with a Pressure Threshold Meter(PTM). After the measurements, in order to compare the ROM of the TMJ, the subjects were divided into two groups based on the ROM of above 35mm and below 35mm. For the deviation and pain, based on the average of total subjects, the subjects were divided into two groups of above and below average. Thereafter, the levels of masseter muscle tension were compared between each pair of groups. According to the results, when each variable was compared between the respective two groups, in terms of the deviation, the pressure pain threshold(PPT) of the masseter muscle revealed a statistically significant difference(p<.05). However, the ROM and pain showed no statistically significant difference. Consequently, masseter muscle tension may cause restricted movement in the TMJ. In particular, the deviation and tension in the masseter muscle is considered to be a factor that causes deviation in the TMJ.

        This study was to investigate pregnancy rate of IVM/IVF/IVC Korean cattle (registered in government) embryos according to transport time course. For the production of embryos, oocytes recovered from slaughtered excellent grade cow and highly motile frozen‐thawed bull semen (purchased from LIMC, KPN#497) was used. In vitro produced embryos were cultured in CR1aa medium for 8 days and some of them were frozen. The rate of average cleavage (>2‐cell) was 83.0% (308/371) and blastocyst rate at day 8 was 34.7% (107/308). Among in vitro produced blastocyst embryos at day 8, most healthy embryos were freshly transferred on production day and some frozen embryos were direct transferred on appropriate day. These embryos were produced in a laboratory, embryo transfer (ET) was planned in 10 areas of the remote island (Jeju) from the laboratory by airplane. Thus, we examined the pregnancy rate in recipient cow according to embryo of transport time course before ET. From embryo transferred 44 recipient cows, overall pregnancy was 40.9% (18/44), these 18 cows were all calved [single, 94% (17/18); twin, 6% (1/18)] and total embryo implantation rate was 26% (19/66). Comparing transport time in the base of 6 hr, pregnancy rate in ET group required less 4 hr (60%, 9/15) was significantly higher than that required more 6 hr (26.3%, 5/19). In direct ET of freezing embryos, the pregnancy rate was 40% (4/10). However, it was difficult to find the meaning of temperature, pH and corpus luteum quality of recipients on comparison of pregnancy rate. When the cell death level of embryos according to storage time in thermos (straw container) before ET was measured by TUNEL staining, apoptotic index was increased with storage time‐dependent. These results demonstrated that long distance transfer of IVM/IVF/IVC embryos is possible and the time of embryo transport is very important for the pregnancy rate on field trial.

        The purpose of this study was to investigate the recognition and demands of forest interpretation programs. Questionnaire survey was carried out to estimate the awareness, necessity, future participation intent, experience, satisfaction and demands of forest interpretation programs with 100 residents living in Jinju city or Gyeongnam region. The data were subject to frequency analysis, correlation analysis, and path analysis. Overall 63% of respondents didn’t know forest interpretation programs, but 52% of respondents recognized the necessity of forest interpretation programs. 52% of respondents had the future participate intent of forest interpretation programs, and 38.3% didn’t know if they would participate. 74% of respondents had never experienced the programs. In the satisfaction, 80% of respondents who experienced showed neutral. Future participation intent was highly correlated with necessity as shown in the result of correlation analysis among awareness, necessity, future participation intent, and experience of forest interpretation programs. Also future participation intent in path analysis was estimated to be affected indirectly by experience and awareness as well as necessity. Enhancement of future participation intent would be achieved by increasing experience, awareness, and necessity of forest interpretation programs. According to the demands, forest interpreters were required to have the expertise to provide knowledge and information of forests. Attractive content for forest interpretation programs was in the order of recreational activities > forest conservation > education while the proper objective of forest interpretation programs was experience and interest > education > conservation and resource > public relation of forests and parks. Respondents preferred participation and experience the most as a style in selecting the programs. Key condition in selecting the venue was diversity > safety > connectivity > accessibility in order. There was no significantly different preference in proper participation duration or operation season for the activities of forest interpretation programs.

        The inflammatory response to infections, such as bacteria and viruses is mediated by multiple host factors. The tumor related-genes are the important cytokines in mammals. However, a number of tumor related-genes are not identified in the rock bream. Here, we have reported the identification and molecular characterization of the tumor related genes. The LPS-induced TNF-α factor 1 and 2 (LITAF1, LITAF2), tumor necrosis factor superfamily member 14 (TNFSF14), tumor necrosis factor receptor superfamily member 14 (TNFRSF14) and translationally controlled tumor protein (TCTP), programmed cell death 10 (PCD10) from rock bream are used for the under investigations. The LITAF1 and LITAF2 consist of 138 and 163 amino acids with a conserved LITAF domain. TNFSF14 and TNFRSF14 comprise 266 and 181 amino acid, respectively. TCTP encompasses of 170 amino acid containing two conserved TCTP signatures. Furthermore PCD10 consists of 210 amino acids. Using quantitative real-time PCR, we have obtained expression analysis results of LITAF1 and 2, TNFSF14, TNFRSF14, TCTP, PCD10 in the various tissue. Compared to the control, the tumor related genes mRNA is detected at a high levels in gill (LITAF1, TCTP), intestine (LITAF2), liver (PCD10), spleen (TNFSF14) and RBC (TNFRSF14). We have also performed gene expression analysis in the kidney, spleen, liver and gill after challenging with Streptococcus iniae, Edwardsiella tarda and Red seabream iridovirus. We have acquired the dynamic regulated mRNA expression to each of pathogen according to the tissue. Expression of tumor related-genes mRNA are significantly increased by infected with pathogens in most of the tissue. But oddly, PCD10 mRNA is expressed significantly decreased by S. iniae infection in all of tissues. Our results reveal that rock bream tumor relatived-genes may be involved in rock bream immune responses to pathogen infections, as well as, they also act like potential biomarkers for innate immunity.

        Translationally controlled tumor protein (TCTP) is one of important immune regulator. TCTP has been implicated in cellular processes including the cell growth, cell cycle progression, apoptosis regulation and the protection of cells against various stress condition. In this study, we cloned and characterized TCTP from rock bream (Oplegnathus fasciatus), which is an economically important species in the Korea aquaculture industry. The Full-length of rock bream TCTP (RbTCTP) cDNA was 1041 bp and contained an open reading frame (ORF) of 513 bp, which encoded 170 amino acid sequence. The 5' untranslated region (UTR) was 90 bp while the 3' UTR was 538 bp, containing a polyadenylation signal (ATTAAA). The identity of amino acid sequence was 76%, 75% and 74% in tilapia, orange-spotted grouper and Japanese seaperch, respectively. The positions of microtuble-binding region, Ca⁺ binding region and TCTP signature regions in RbTCTP were similar with those of other fish species and mammalian. The RbTCTP mRNA was expressed highest in the muscle. Expression of TCTP mRNA were significantly variable according to injection of red seabream iridovirus (RSIV), Streptococcosis (S. iniae) and Edwardsiella tarda (E. tarda).

        Cereal seeds, sorghum, foxtail millet, hog millet, adlay, and corn are traditionally used as health assistant as well as energy supplying food in Korea. While beneficial phytochemicals to human have revealed in cereals, the information on peptides from cereals is far less accumulated than major reserve protein. Here, we analyzed peptide profiles using surface enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF MS) in cereal seeds for construction of peptide information and attempted to develop peptide biomarkers for cereal identification. To optimize the analysis condition of SELDI-TOF MS, the effect of dilution factor on binding affinity to protein chips was tested using CM10 and Q10 arrays. Peptide clusters were significantly different at the level of 0.01 p-value. Peak spectra were the most stable in 1:50 of dilution factor in both chip arrays. Numbers of detected peak of 5 cereal seeds were 131 in CM10 and 74 in Q10 array. Each cereal was grouped as a cluster and well discriminated into different cluster in the level of 0.01 p-value. Numbers of potentially identified peptide biomarkers are 11, 13, 9, 5 and 12 in sorghum, foxtail millet, hog millet, adlay and corn, respectively. This study demonstrates that each cereal seed have own distinguishable specific peptides although their function are not identified yet in this study. In addition, the proteomic profiling using SELDI-TOF MS techniques could be a useful and powerful tool to discover peptide biomarker for discrimination and assess crop species, especially under 20 kDa.
