A survey was conducted to analyze seasonal dynamics of the phytoplankton community at 22 stations on the surface and bottom layers in the Anma Islands of Yeonggwang (AIY) in the southern West Sea, Korea from the spring of 2020 to the winter of 2021, using a marine survey vessel Ed Ocean. Based on the survey results, there were 87 phytoplankton species in 52 genera, diatoms accounted for 67.8%, dinoflagellates 26.5%, silicoflagellates 3.5%, and cryptomonads and euglenoids accounted for 1.1% each. By season, it was simple in spring and relatively varied in winter. The phytoplankton standing crop on the surface was low (28.8±30.1 cells mL-1) in summer and high (87.0±65.1 cells mL-1) in spring. In the phytoplankton community, diatoms showed a high share (over 80%) throughout the year, and Skeletonema costatum-ls was the dominant species with a dominance of more than 60% in spring and winter, and 34.6% and 24.2% in summer and autumn, respectively. The diversity expressing the characteristics of the community structure was high (2.79±0.45) in autumn and low (1.82±0.18) in spring, unlike the phytoplankton standing crop. However, the dominance was high at (0.86±0.08) in spring and low (0.44±0.13) in autumn. Based on the results of principal component analysis (PCA) using environmental and phytoplankton-related factors, it was estimated that the biological oceanographic environmental characteristics seen through the phytoplankton community in the AIY were dominated by nutrients supplied from open seawater and surface sediments by seawater mixing, such as tidal mixing.

Nowadays, importance of regional specific on-farm research is largely increased in order to reduce the feeding cost of cattle. For this project, three regional districts (Yeongam, Yeonggwang and Jangheung) were selected wherein the cultivation area of forage production were largely increased from 1,200 ('08) to 2,600 ㏊ ('09) in Yeongam, 1,001('08) to 1,925 ㏊ ('09) in Yeonggwang, and 1,300 ('08) to 2,820 ㏊ ('09) in Jangheung district. Among the forage species, Italian ryegrass (IRG) and forage barley were predominantly cultivated in these regions. On the other hand, rye, grassland and summer annual forages were cultivated very little in a manner of land area. The productivity of forage barley was slightly increased 21.5('06), 26.2('07), and 27.3 MT/㏊ ('08) as silage. The number of farm and cultivation area was also increased remarkably. The present research project will be conducted from 2009 to 2010. Forage production and utilization for reduction of feeding cost, and high quality of Hanwoo beef production will investigated, in a manner of cultivation of forage crops mainly IRG, forage barley, IRG+barley mixture and corn.

Background : Ramie, Boehmeria nivea (L) Gaud, is a bast fiber plant of the nettle family (Urticaceae) and originated in Asia. We have taken an active interest in ramie breeding for edible ramie, and consequently select "Yeonggwang No.1" with high yielding and good quality for edible leaves in 2015. Methods and Results : "Yeonggwang No.1" is a new ramie variety for edible leaves, which was derived from the plants of the population for pure clone isolation from 2013 to 2014, and progressively for specific character and yield trial in 2014 to 2015. The yield trials were carried on the field and the greenhouse with two replications, respectively. The plant height of "Yeonggwang No.1" is about 140 ㎝ with 6 ㎝ higher than that of check variety "Seobang" The leaves are heart-shaped, with large size, and finely serrated margins. The color of the upper side of the leaf is dark green, and silvery white on the under surface. The flowers are light purple in color and are borne in declinate clusters in the axils of the leaves. The average SLW (specific leaf weight) was 8.56 ㎎/㎠, which was weight lighter than that of check "Seobang", but chlorophyll content measured by a Chlorophyll meter, SPAD-502 was 12.3 SPAD higher than that of "Seobang". Fresh leaf yield was the annual total 1,578 ㎏/10 a in the field, and 2,479 ㎏/10 a in the greenhouse, which was 98% level of "Seobang" in the field, and increased by 10% than check "Seobang" in the greenhouse. The fresh leaves yield of "Yeonggwang No.1" tended to increased in changes according to time more than "Seobang". Conclusion : As a new variety, Yeonggwang No.1 can be harvested leaves several times annually, with the yield range of 1,578 – 2,479 ㎏/10 a, having 72.3% moisture, 6.61% crude protein, 987 ㎎ calcium, 5.27 Fe in its leaves. These results seem to indicate that there is considerable scope for increasing the fresh leaf yield of ramie and improving the processing quality by means of selection from the large and comparatively unexplored pool of variation, which should be obtainable from this heterozygous plant.

Recently, the food industry has evolved into a new and innovative trend according to its globalization and change of food consumption patterns. However, it is hard for the traditional food industry in Korea to meet the changing consumers' needs because of its poorer quality control and lower industrialization technology than other advanced industries. Also the knowledges acquired through a lot of time and efforts would be lost after the human resources with tacit knowledges leave by their too much aging. Especially, the 21st century would be called as knowledge based society which means that knowledge be the important contributing factor in the economic growth. In this regard, this study aimed at proposing the knowledge based system for systematically managing or preserving knowledges of Mosisongpyun industry in Yeonggwang County to seek for the sustainable development of the traditional food industry in Korea. The knowledge based system of Mosisongpyun industry in Yeonggwang County is finally proposed as follows; First, hardware is composed with the necessary unit facilities such as interpretive center, learning and experience room, library, etc. And the integrating facilities such as Mosisongpyun theme park, traditional village, and knowledge industrialization support center are proposed. Second, software is composed with the necessary unit softwares such as the preservation manual of traditional knowledge and skill, web-site administrator, development of graded textbooks, development database software, etc. And the integrating softwares such as development of innovation and management ability in Mosisongpyun industry are proposed. Third, humanware is composed with the necessary unit programs such as exhibition, own training program, incubator support system, etc. And the integrating programs such as the farm association corporation, the testing and research institute, the institution of learning and training are proposed.
