        This study was carried out to investigate insect community structure from different habitats. We performed day and night collection at three different habitats (mountain, coast and rural area) of island Deokjeok, island Soya and island Mungap from May to September in 2014. A total of 3,482 individuals of 725 species, 119 families belonging to 10 orders were collected and identified. A dominant species was Corymbia rubra (Cerambycidae) despite a very low percentage of the species among the catches. Results of ANOVA test showed a significant effect of habitats typeon species diversity. Also, combination of seasons and habitats types were significantly influential with species abundance and species diversity. Indicator species analysis (ISA) result identified 121 significant (p < 0.05) indicator species; one species for the habitats cluster, 93 species for the season cluster and 27species for combination of habitats with seasons.

        An insect faunal survey was carried out to investigate insect community structure along the vegetation community to monitor insect species in forest ecosystem. We performed day and night collections from June to August along three vegetation communities of Is. Nam-hae in 2014: the first stand with Pinus thunbergii, the second P. thunbergii with Quercus serrata and the third P. thunbergii with various Quercus species. In total 2,259 individuals of 532 species, 99 families, 13 orders are identified. Cluster Analyses (CA) showed that all three vegetation communities were relatively similar between vegetation community types. According to indicator species analysis (ISA) result, nine significant indicator species were identified (p < 0.05); five species were found to be affected by the vegetation cluster and four species the month cluster.

        A long term monitoring was carried out to compare altitudinal effects on insect community structures on high mountains and evaluate responses the monitoring and changed of insect communities induced by the climate change. These mountains were choose for Mt. Jeombong for northern part, Mt. Ilwol for middle and Mt. Beakun for southern. Each mountain was divided into three altitudinal gradients. They were collected three times a season from spring to autumn, using pitfall traps for ground beetles and UV light trap for moths. The present study presents preliminary results of analysis for the first year monitoring. In total 41beetle species and 326 moths were collected from the monitoring sites in 2012. abundance of ground beetles and moths were the highest in Mt. Baekun followed by Mt. Ilwol and lowest in Mt. Jeombong. Analysis of variance (ANOVA) results showed statistically significant differences among sampling area, species evenness and Shannon’s diversity index with altitude in species abundance as a response variable. Also we found statistically significant differences to three species of ground beetle and six species of moths with altitude. Although we expected a distinct cluster with the difference of altitude at each study site. one of ordination analysis, nonmetric multidimensional scaling (NMS), showed distinct clusters with the ground beetles assemblage at some altitude and moths assemblage at sampling date.

        Somatic cell nuclear transfer in cattle has limited efficiency in terms of production of live offspring due to high incidence of fetal failure after embryo transfer to recipients. Such low efficiency of cloning could possibly arise from abnormal and poorly developed placenta. In the present study the placental proteome in late pregnancy established from in vitro fertilization (IVF) and nuclear transfer (NT) was analysed. Proteome alternation was tested using two-dimensional polyacrylamide gel electrophoresis (2-DE) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI- TOF). Comparing placenta from NT embryos to those from IVF counterparts, significant changes in expression level were found in 18 proteins. Of these proteins 12 were not expressed in NT placenta but expressed in IVF counterpart, whereas the expression of the other 6 proteins was limited only in NT placenta. Among these proteins, cytokeratin 8 and vimentin are considered to be involved in regulation of post-implantation development. In particular, cytokeratin 8 and vimentin may be used as makers for placental development during pregnancy because their expression levels changed considerably in NT placental tissue compared with its IVF counterpart. Data from 2-DE suggest that protein expression was disorientated in late pregnancy from NT, but this distortion was eliminated with progression of pregnancy. These findings demonstrate abnormal placental development during late pregnancy from NT and suggest that alterations of specific placental protein expression may be involved in abnormal function of placenta.

        “Greenstar”, a new Saxifraga cultivar was bred by crossing between “Geumgongjak” with green (YG145C) petals and “Rokseon” with red purple (RP62A) petals in 2003. The selection and flower characterization were conducted from 2003 to 2006 in greenhouses of the National Institute of Highland Agriculture. The flowering of “Greenstar” starts on September 17 for 36 days and the number of flowers per plant was about 290. The flower color is a green (G142C) and the number of petals was 5. Flower width is 2.1 cm and flower length is 1.9 cm. “Greenstar” can be used for pot flower. Fifty percent shading is a good cultural practice against direct sunlight and soft rot disease would occur usually by over-irrigation.

        A new Saxifraga cultivar “Snowmaple” was bred by crossing between “Jeokhoamugab” with red purple (RP68B) petals and “Hongsaja” with red purple (RPN66A) petals. The selection and flower characterization were conducted from 2004 to 2006 in greenhouse of the National Institute of Highland Agriculture. The flowering of “Snowmaple” starts on October 9 for 16 days, The number of flowers per plant was 315 with strong concurrent flowering habit. The flower shows red purple (RP62C) at opening, but It turns gradually changable from red purple to white. The flower has 5 petals, and the size is 2.0 cm in width and 2.3 cm in length. “Snowmaple” can be used for pot flower. Fifty percent shading is a good cultural practice against direct sunlight and soft rot disease would occurs usually by over-irrigation.
