  • This study is intended to analyse the economic sensitivity of imported fishery products due to decrease in or elimination of tariff rates through the progress of free trade. Forty-seven species of fishes were selected for this study on the basis of the HS Code. The substitution and price effects were calculated using the price elasticities of both domestic and imported demands for fishery products under the assumption of 5% decrease in a tariff rate. Seven main economic variables were extracted from the fishery industry which can mediate the substitution and price effects. A multiple regression analysis was conducted to obtain the influence weights of these main economic variables on both effects. The order of sensitivity of the fishes was calculated using these weights. The 47 fish species were classified into four groups according to their sensitivity based on the means and the standard deviations of their total scores on seven main economic considerations. Nine fish species such as squids, hair tails, shellfishes, and crabs belonged to the hyper-sensitive group, whereas 15 fishes such as eels, sea breams, and sea weeds belonged to the sensitive group. Twelve species including common sea basses, cods, and abalones were among the less-sensitive group, and 11 species including skate rays and mud fishes comprised the non-sensitive group.

  • Daewungbojeon hall of Magoksa temple is a korean traditional wood building well representing Joseon Dynasty architecture in the 17th century. The purpose of this study was to identify the wood species of 42 wooden elements collected from Pillar (Gidung), Head-penetrating tie (Changbang), Pyeongbang, Angle rafter (Chunyeo), End-angle rafter (Sarae) and Hwalju. According to the microscopical investigation, Pillar, Head-penetrating tie, Pyeongbang and Hwalju were identified as domestic hard pine species. However, Chunyeo were identified as either Zelkova serrata Makino or Gingko biloba L. and Sarae as exotic hard pine species. It might be related to the high replace rate of wood elements for the roof. Especially, exotic hard pine species seem to be replaced in recent years when Daewungbojeon hall was repaired.

  • Water Pollution of Gwangju Stream was examined for four months from 22 March 1981 to 7 June, 1981. For checking the water pollution, 6 sampling positions were selected 5 from main stream. We assumed that the water pollution of Gwangju stream was due to the organic materials, which came from the domestic sewage. The apparatus for this test were pH meter (Orion model 301), Dissolved Oxygen & Temperature meter(Delta model 1010). The results we obtained are as follows: 1. The average range for mid-stream(sp. 3, 4) was 3. 10~2.73ppm of Dissolved Oxygen(DO), 80.23~102.95ppm of Biochemical Oxygen Demand (BOD), 195. 10~165.90ppm of Suspended Solid (SS), 6.6~6.7 of pH. 2. The plankton identification in this survey period showed Cyanophyceae is 4 genera 5 species, Bacillariophycea 11 genera 14 species, Chlorophyceae 8 genera 15 species and Zooplankton 6 genera 7 species: total 29 genera 41 species. 3. To appear dominant plankton in polluted water, there were Paramecium, Euglena and Oscillatoria. 4. The results of biological water analysis were as follows: st. 1 was B-mesosaprobic to oligosaprobic, but st. 4 and st. 5 at stream in the midtown area seemed to be polysaprobic.

  • Time and cost-effective production of next-generation sequencing data has enabled the performance of population-scale comparative and evolutionary studies for various species, which are essential for obtaining the comprehensive insight into molecular mechanisms underlying species- or breed-specific traits. In this study, the evolutionary and functional analysis of Korean native pig (KNP) was performed using single nucleotide polymorphism (SNP) data by comparative and population genomic approaches with six different mammalian species and five pig breeds. We examined the evolutionary history of KNP SNPs, and the specific genes of KNP based on the uniqueness of non-synonymous SNPs among the used species and pig breeds. We discovered the evolutionary trajectory of KNP SNPs within the used mammalian species as well as pig breeds. We also found olfaction-associated functions that have been characterized and diversified during evolution, and quantitative trait loci associated with the unique traits of KNP. Our study provides new insight into the evolution of KNP and serves as a good example for a better understanding of domestic animals in terms of evolution and domestication using the combined approaches of comparative and population genomics.

  • We investigated the effects on various crops of inoculation with species of arbuscular mycorrhizal fungi (AMF) in soils from different sources and selected AMF species suitable for domestic environment-friendly farming. Effects on plants varied with the AMF species used. In carrot, Scutellospora heterogama, Acaulospora longula, and Funneliformis mosseae had a positive effect on growth of the host, whereas AMF had only weak effects on the growth of red pepper and leek. AMF inoculation had positive effects on the growth of carrot and sorghum. The results of this study indicate the nature of the relationship between soil, plants, and AMF; this study therefore has important implications for the future use of AMF in environment-friendly agriculture.

  • The genus Philanthus Fabricius, 1790 in Korea are reviewed, and two species, Philanthus triangulum and P. coronata, are treated. The former is new to Korea. This species is easily separated from congeners by dense punctures in propodral enclosure and tri-forked marking in lower face. DNA barcoding test is supportive in our identification as well as conspecitficity of Korean materials showing variation in size and coloration. The observed data on flower associations of this species specified with domestic localites and date are separately provided. The current status of Philanthus coronatus that has been the only representative of the genus but forgotten for a lengthy time in Korea is discussed.

  • The extract contents of various Phellinus species (Hymenochaetaceae) including P. linteus, P. baumii, P. pini and P. igniarius of domestic and foreign products, were examined to standardize the quality of these products. The differences of various extract contents were identified and compared between different species of Phellinus products. The thin layer chromatographic patterns were also analyzed and six unidentified samples were thought to originate from P. baumii and P. igniarius. The chemical standardization for the quality control of various origins could be suggested by this study.

  • The nucleotide sequence of the domestic silkworm (Bombyx mori) mitochondrial (mt) control region and its flanking genes was determined from PCR clones. The control region of the silkworm mt genome was located between the small ribosomal RNA gene and transfer RN $A^{Met}$. This 499 bp control region hale 95.4% A+T content. Extensive comparative analysis studies performed with similar control region of other insect genomes could not reveal a highly conserved region containing conserved motifs of animal mito-chondrial genome. The remarkable feature that found in this control region was the presence of tandem motifs containing nine repetitive sequences. The potential usefulness of this motif sequences for Bombyx species or their taxonomically related species is enhanced by its unique localization in the maternally inheritance mitochondrial molecule.e.

  • V8 juice agar (V8A) has been the most popular and commonly used medium for growth and reproduction of Phytophthora. However, frequently V8 vegetable juice is not available or difficult to obtain in Korea. We therefore developed widely accessible medium to substitute for V8A using domestically available five juices; two carrot (KCJA), two tomato (KTJA) and a vegetable-mix (KVMA). To prepare 10% juice medium, each vegetable juice 100 ml, DW 900 ml, agar 17 g and Ca CO3 0.5∼1.0g were supplemented to adjust pH ca. 6.0 Mycelial growth of P. cactorum and P. capsici on KTJA and KVMA was equally effective as V8A for the growth of P. cactorum, P. capsici, P. drechsleri and P. nicotianae under light. Sporangial production of P cactorum, P. capsici and P. nicotianae on KTJA and KVMA was as good as V8A and slightly better than CKJA, but the difference was insignificant by P. cactorum and P. nicotianae. The four fungi successfully formed oospores on all the media although the numbers were varied among species and media. While KTJA was the best for P. cactorum and P. capsici, V8A was the best for P. capsici and P. drechsleri. However, KCJA stimulated highest number of oopspores of P. nicotianae. Overall results showed that domestically available vegetable juices were highly effective on growth and reproduction of Phytophthora and comparable to V8 juice. Therefore, the domestic juice medium can be successfully replaced V8A in Phytophthora study.
