  • The purpose of this study is to examine the effect of sympathetic reactions to public service advertisement video messages produced for health campaigns. To this end, based on the empathy response scale proposed by Campbell & Babrow (2004), the empathy response to the images of nine health campaigns with themes of smoking cessation, tuberculosis, and suicide triggered fear of health risks and health behaviors (information seeking, preventive actions). As a result of the analysis, among the factors of empathy reaction, the reality of the message creative, the match of emotions, and the identification of the characters in the video each played a role in raising fear, and it is rather fear that logically understanding the situation that causes health problems through the health campaign video It was found that it played a role in reducing health information seeking behavior. On the other hand, it was found that the higher the degree of interest, such as sympathy for the characters in the video, among the factors of the sympathetic response to the health campaign, the higher the intention of preventive action to reduce the health risk.

  • Stock identification of Todarodes pacificus collected in the East Sea, Yellow Sea and East China Sea during the period from September to December in 2011 was analyzed by morphometric characters and mitochondrial DNA (mtDNA) cytochrome oxidase subunit I (COI) gene nucleotide variations. Frequency distributions of mantle length was analyzed by morphological method with measuring size of T. pacificus. Then each stock was estimated to confirm their maturation for mean mantle length comparing with mean mature mantle length 20-22 cm. According to morphologic stock identification, it is estimated that the northern part of East Sea is categorized as summer stock and the rest parts, including mid /southern part of the East Sea, northern part of the East China Sea and northern part of the West Sea were autumn stock. For genetic analysis, a total 49 haplotypes were defined by 33 variable nucleotide sites. From the extensive haplotype diversity, limited nucleotide diversity and star-like shape of haplotype network, T. pacificus appears to have undergone rapid population expansion from an ancestral population with a small effective population size. Although pair-wise Fst estimates which represent genetic difference among groups were low, there are relatively remarkable difference of Fst between middle and southern part of the East Sea. Although middle part of the East Sea and southern part of the East Sea were situated at the East Sea, genetically separated groups were appeared.

  • Taxonomic treatment and the identification key for 6 species and 4 varieties from the genus Asarum (Aristolochiaceae) in Korea were presented on the basis of the morphological analyses. Recently the taxonomy of the genus Asarum in Korea is controversial in the definition of species and the establishment of variation range. Our morphological studies supported that the species A. patens, A. misandrum and A. versicolor should be recognized as independent species by the unique morphological characters such as calyx lobes, stylar protuberance and leaf variegation. Second, A. sieboldii var. cornutum, A. koreanum, A. maculatum and A. sonunsanense, regarded as species or variety by different scholars, showed a close relationship with A. sieboldii by the similar calyx characters. Thus, new combinations, such as A. sieboldii for. cornutum, A. sieboldii for. koreanum, A. sieboldii for. maculatum and A. sieboldii for. sonunsanense, are proposed. And A. heterotropoides var. seoulense and A. heterotropoides var. mandshuricum also had a close relationship, thus, new combinations, A. mandshuricum for. seoulense, A. mandshuricum for. mandshuricum, are proposed. Furthermore, it is appropriate that A. heterotropoides var. heterotropoides, only distributed in Japan, is revised into A. heterotropoides as independent species by the unique character from the 2 varieties above. Consequently, the genus Asarum in Korea is classified into 3 species and 7 forma.

  • For nine taxa of the genus Carex which consist of C. arenicola, C. chordorhiza, C. curta, C. gibba, C. laevissima, C. leiorhyncha, C. neuromrpa, C. maakii and C. remouscula with mixed pistillate and staminate flowers, morphological characters such as inflorescense, spikelet, inflorescence bract, utricle, pistillate and staminate scales, achene, length between two spikelets were observed to find useful characters for their identification. Especially, the shape and the number of spikelet were very useful characters to divide the treated nine taxa into two groups, the their keys were prepared. The first group was comprised of five species of C. arenicola, C. chordorhiza, C. curta, C. gibba, and C. remouscula, which were characterized by broadly oboval or narrowly elliptical shape of spikelet, and 3-9 spikelets per infIorescence and gradual decrease in length between two spikelets. The second group was composed of four species of C. laevissima, C. leiorhyncha, C. neurocarpa, C. maakii, which were distinguished by oval shape of spikelet, and 17-20 spikelets per infIorescence and repetition of increase.

  • Screening and identification of genetic resources based on their phytoconstituents and morphological characters potentially provide baseline data for researchers, breeders, and nutraceutical companies who wish to formulate a nutrient-dense diet and health beneficial supplement. Thus, we evaluated the amount of total phenolic content and major phenolic compounds; examined if phenolic compounds could be used as distinguishing factors for perilla genetic resources; and investigated the relation between some quantitative and qualitative morphological characters with the contents of phenolic compounds in 360 accessions obtained from National Agrobiodiversity Center gene bank, Jeonju, Korea. Total phenolic content (TPC) was estimated using Folin-Ciocalteu colorimetric assay. Individual phenolic compounds were determined using an Ultra-High Performance Liquid Chromatography system equipped with Photodiode Array detector. Considerable variations were observed in TPC (7.99 to 117.47 mg GAE/g DE), rosmarinic acid (RA) (ND to 19.19 mg/g DE), caffeic acid (CA) (ND to 0.72 mg/g DE), apigenin-7-O-diglucuronide (ADG) (ND to 1.24 mg luteolin equivalent (LUE)/g DE), scutellarein-7-O-glucuronide (SG) (ND to 4.32 mg LUE/g DE), and apigenin-7-O-glucuronide (AG) (ND to 1.60 mg LUE/g DE). RA was the most dominant phenolic compound in most accessions (95.3%) followed by SG. The adaxial leaf color was light green, green and dark green in 13.8%, 65.0%, and 21.1 % of the accessions, respectively. 78.8% of the accessions had light green color at the abaxial side with the remaining being described as green. Most of the accessions (96.9%) were cordate shape, the remaining being eclipse. Intensities of green pigment at abaxial and adaxial leaf surfaces were correlated with contents of individual phenolic compounds and TPC whereas leaf length and width had no correlation with TPC, CA and RA, and negatively correlated with ADG, AG, and SG. Leaf shape was not related with content of phenolic compounds, color of leaves, or the length or width of leaves. Accessions IT57426, IT157434, IT267710, and IT267712 which contained relatively high contents of TPC and major phenolic compounds (RA and SG) could be used for further research in breeding and bioassay test. Our study result showed the contents of total phenolics and individual phenolic compounds along with the morphological characters could be useful distinguishing factors for perilla genetic resources.

  • We reported that amorphous silicon (a-Si) thin film provide sample plate exhibiting a multimodality to measure biomolecules by secondary ion mass spectrometry (SIMS) and laser desorption/ionization mass spectrometry (LDI-MS). Kim et al.1 reported that a-Si thin film were suitable to detect small molecules such as drugs and peptides by SIMS and LDI-MS. Recently, bacterial identification has been required in many fields such as food analysis, veterinary science, ecology, agriculture, and so on.2 Mass spectrometry is emerging for identifying and profiling microbiology samples from its advantageous characters of label-free and shot-time analysis. Five species of bacteria - S. aureus, G. glutamicum, B. kurstaki, B. sphaericus, and B. licheniformis - were sampled for MS analysis without lipid extraction in sample preparation steps. The samples were loaded onto the a-Si thin film with a thickness of 100 nm which did not only considered laser-beam penetration but also surface homogeneity. Mass spectra were recorded in both positive and negative ionization modes for more analytical information. High reproducibility and sensitivity of mass spectra were demonstrated in a mass range up to mass-to-charge ratio(m/z) 1200 by applying the a-Si thin film in mentioned above MS. Principle component analysis (PCA) - a popular statistical analysis widely used in data processing was employed to differentiate between five bacterial species. The PCA results verified that each bacterial species were readily distinguished and differentiated effectively from our MS approach. It shows a new opportunity to rapid bacterial profiling and identification in clinical microbiology. More details will be discussed in the presentation.

  • To clarify the key characteristics of Korean brown frogs (R. dybowskii, R. huanrenesis and R. amurensis coreana), this study employed a morphological and morphometrical comparisons among brown frogs found in Korea and Japanese endemic species, R. tsushimensis. As a result, it was considered that the key characteristics were the shape of the finger and toe tips, the markings of the lower jaw, the presence or absence of an upper lip line, the development of toe webbing, and the shape of the vomerine teeth series by morphological comparisons of brown frogs. Also, there were significant differences in tympanum diameters and foot lengths of the four species of brown frogs. Therefore, a comparison between morphological and morphometric characters is an effective way to clarify the identification of brown frogs.
