  • This study was carried out to investigate the characteristics survey of Clavicorona pyxidata strains. C. pyxidata are selected 3 kinds of strains collected in GWANG DEOCK Mt., DO BONG Mt., and BUK HAN Mt., Mycelial growth of C. pyxidata collected from GWANG DEOCK and BUK HAN Mt. is 64mm, 60mm for 18days respectively. DO BONG Mt strain is 85mm for 9 days. Transparent crystal body of C. pyxidata mycelia were appeared by microscopic examination of 100 magnification. Optimal temperature of mycelial growth in C. pyxidata strains are 25~30℃ respectively.

  • In an ongoing survey of Korean indigenous fungi, three fungal strains belonging to the Sordariomycetes were isolated from soil samples. These strains were designated KNU16-001, KNU16-002, and KNU16-009, and identified as Ambrosiella grosmanniae, Acremonium sclerotigenum, and Trichocladium asperum, respectively, based on morphological characterization and phylogenetic analysis using internal transcribed spacer region sequences of ribosomal DNA. This is the first report of these species in Korea.

  • The purpose of this study is to suggest an improvement plan for the National Technical Qualification Practical Evaluation focusing on National Competency Standards. First, in order to strengthen practical techniques such as field abilities and expertise, practical evaluation methods were applied to the National Competency Standards, referring to a learning module focused on field performance. Second, an expert advisory committee in the field of organic agriculture was utilized to compare, analyze, and match the competency unit and competency unit elements of the National Competency Standards with the national technical qualification examination standards in field of organic agriculture. In addition, in order to identify work in progress in the industrial field, share professional practice skills, and analyze facilities and equipment, we visited an organic agriculture industry site. Through this, a practical evaluation exam was developed. Subsequently, in order to confirm the adequacy of the developed exam, the pilot test assessment was conducted for those majoring in organic agriculture. Finally, as a feasibility study, a survey was conducted. Based on the results, greater technical job competency in the field of organic agriculture will contribute to strengthening knowledge in this field by suggesting an improvement plan for the national technical qualifications practical evaluation method in the field of organic agriculture.

  • This study suggest strategies to expand pork exports to Hong Kong through understanding characteristics of its pork market based on results from analysis on surveys on consumers and marketers. The survey results indicate that Hong Kong's consumers consider freshness and sanitation/safety of pork as the most important factors in their purchase. The consumers are found to be very satisfied with Korean pork and have intension to purchase it in the future. The importers suggest that Korean pork should improve its price competitiveness and build up its brand images. Based on results of surveys, this study suggests four strategies, which are systematic disease controls, establishment of its brand image, effective quality and sanitation/safety management and government supports. And, as results from deriving economic effects of 2021 Korean pork export to Hongkong, the production inducement effect is 42.5 billion won and the employment inducement effect is 266 persons.

  • A fungal isolate belonging to the phylum Ascomycota was isolated and identified as Talaromyces veerkampii in 2017 during a survey of fungal diversity in field soils in Korea. This fungal isolate was identified and described based on macro- and micromorphological and molecular characterization. The identification was also based on partial 18S-ITS1-5.8S-ITS2-28S rDNA and calmodulin (CaM)-encoding gene sequencing data. Talaromyces veerkampii has not been previously reported in Korea. Thus, we report here a newly discovered species from soil in Korea along with its morphological and molecular characteristics.

  • This study attempts to derive measures to improve content claims of free antibiotic livestock products(FLP) through analyzing situations for the FLP market and results of survey for its providers. Recently the number of certified farms has been decreasing, but shipments per farm has been increasing. Furthermore as the COVID-19 has increased health and environmental concern, shipments of FLP have showed a steady increase. The distribution channel of FLP, regardless of varieties, is similar to that of general livestock products(GLP). The major results from survey for providers of FLP are little difference in between content claims of GLP and FLP and low utilization of FLP in production of livestock processed products compared with its shipments. The policies for content claims of FLP suggested by this study are permission of FLP authentication labelling for livestock processed products and permission of those which contain FLP over 70% in the first step.

  • A survey on the Eperythrozoon infection of cattle was conducted by means of examinations of Giemsa staining blood films obtained from 2,263 cattle which had been fed in the middle and south parts of Korea. On the other hand, continuous hematological examinations to five splenectomized calves were performed. The results obtained were summarized as follows: 1. Eperythrozoon wenyoni were detected in the blood films of five cattle from Kyungpook and Cheju areas. 2. The infections of Eperythrozoon wenyoni were observed in four of five splenectomized calves from Taegu and Sungwhan areas. 3. From these results it is considered that the infections of Eperythrozoon wenyoni in cattle are quite common in the middle and south parts of Korea.
