  • The 5th century kiln that produced pottery coffins was found for the first time in Korea, located in the Oryang-dong remains in the city of Naju. This kiln, located in the central area of the Yeongsan River, provides important data for research on mortuary practices in prehistoric society, including the structure of production and patterns of distribution and consumption. For this study, the remains of five ancient tombs and pottery coffins excavated from the 4th century Mandong archaeological site were chosen to determine the area of consumption of pottery coffins produced at the Oryang-dong kiln. The samples from each area of remains were analyzed for minor elements using neutron activation analysis method, and from these results, the identities of the corresponding production areas were investigated using the multi-variant statistical analysis of discriminant analysis. The evidence strongly suggests that pottery coffins produced at the Oryang-dong kiln in Naju were used in ancient tombs of the Bannam mound in Naju, the Okyari mound in Yeongam, and the Banam mound in Hampyeong, reaching those sites through trade and distribution. The findings also suggest that pottery coffins from the Mandong archeological site in Gochang and the Inpyeong mound in Muan were not produced at the Oryang-dong kiln in Naju, but rather were brought from pottery kilns in different production areas, through trade and distribution.

  • Red saprolites are appeared in granitic hills in Naju, Southern Korean Peninsula. These red saprolites were analyzed for their geochemistry, including CIA, A-CN-K and A-CNK-FM ternary plots, to understand the chemical weathering trend and rubefaction of the saprolites. These saprolites were compared with kaolinitic saprolites of Guadalquivir Basin in Spain formed under paleo-humid tropical conditions. Chemical Index of Alteration(CIA) value for Naju in Korea is 80, and 87 in Guadalquivir, suggesting moderate and strong weathering in both. Relative to kaolinitic saprolite of Guadalquivir in Spain, red saprolites in Naju are commonly weak loss of CaO, $Na_2O$, especially in $K_2O$. The A-CNK-FM ternary plots of Naju saprolites relative to Kaolinitic saprolites of Guadalquivir shows weak chemical alteration owing to slow removal of $K_2O$, but high mafic constituents, $Fe_2O_3$ and MgO, for most of the samples. In the saprolites of Naju, mafic oxides, $Fe_2O_3$ and MgO, become enriched because of the fast and massive removal of CaO, $Na_2O$ and $K_2O$ relative to other elements, resulting in rubefaction of the surface layer of the saprolites, so more redness than kaolinitic saprolites of Guadalquivir. It is found that the rubefaction of the saprolites is not necessarily proportional to chemical weathering intensity.

  • 올해 초 종오리농장에서 고병원성 조류인플루엔자가 발생하면서 국내 양계산업은 또 다시 큰 위기를 맞이했다. 과거 발생현황과 달리 6월에도 고병원성 AI가 발생하여 양계인들의 큰 걱정거리가 되었으며 기나긴 AI와의 싸움은 지난 9월 4일 AI 위기단계를 경계에서 관심으로 하향조정하고 전국에 걸쳐 설정되었던 방역대 및 이동제한조치를 해제하면서 AI 공포로 벗어나는듯 했지만 9월 24일 전남 영암 육용오리에서 또 다시 고병원성 AI가 발생하고 방역대 내 는 물론 전남 나주지역까지 발생하여 큰 우려를 자아내고 있다. 따라서 AI 확산 및 전파를 막기위해 농가에서 자율적으로 할 수 있는 방역활동 내용을 요약 정리하였다.

  • Main aspect of this study are to clarify mineral compositions on granites in Youngkwang-Naju area. These granites are is divided into four rock facies based on the geologic ages, mineralogical composition and chemical constituents, and texture : hornblende-biotite granodiorite, biotite granite, porphyritic granite and two mica granite. These granites constitude an igneous complex formed by a series of differentiation from cogenetic magma. In compressive stress field between the Ogcheon folded belt and the Youngnam massif, the foliated and undeformed granites had formed owing to heterogeneous distribution of stress. The geochemical data of study area indicate magma of these rocks would had been generated by melting in lower and middle crust. The major minerals of granitic rocks in study area are plagioclase, biotite, muscovite and hornblende. Plagioclase range in composition from oligoclase ($An_{19.3-27.7}$) to andesine ($An_{28.4-31}$), and shows normal zoning patterns, This uniformed composition indicated slow crystallization, and it is obvious that the growth of these crystal occurred before final consolidation of the magma. The Mg content of biotite are increases with increasing of $f_{O2}$ and grade of differentiation, changing from phlogopite to siderophyllite. Its $Al^{iv}$/$Al^{total}$ ratios are propertional to bulk rock alumina content. Muscovite is primary in origin with high content of $TiO_2$, and Its composition correspond to celadonitic muscovite. Hornblende indicated calc amphibole group ($(Ca+Na)_{M4}{\geq}1.43$, $Na_{M4}<0.67$). and consolidation pressure of granitic body by geobarometer of Hammerstrume and Zen show 11.3~17.2 Km.

  • Stable carbon and nitrogen isotope results recorded in human bone reflects palaeodiet, nutrition, subsistence and palaeoenvironment. We analyzed the remains of the Naju Yeongdong-ri people, who live at around $6^{th}$ century, excavated from stone chambers and stone-lined tombs. The following results of the analysis of stable carbon and nitrogen isotopes were obtained: ${\delta}^{13}C=-19.5{\pm}0.7$‰, ${\delta}^{15}N=9.6{\pm}0.7$‰, (n=9). The value for stable carbon isotopes indicates that the Naju Yeongdong-ri people had a largely $C_3$-based diet such as rice, barley, and beans. On the other hand, the value for stable nitrogen isotopes reflect the consumption of terrestrial animal protein. This study presents new information on the dietary patterns of the Naju Yeongdong-ri people, whose tombs were similar to the Baekje tomb style and their burial type was much like the one followed by the indigenous people of the Yeongsan river basin.

  • 홍민어, Sianops ocellatus는 미국 플로리다에서 멕시코 중부지역에 이르는 대서양 연안에 분포하며 160cm 까지 성장하는 대형종으로, 맛이 우수한 것으로 알려져 양식대상종으로 기대되고 있는 어종이다. 미국에서는 1980년 중반부터 종묘생산에 성공하여 산업화된 종으로 중국에서는 양식산업화 단계이다(국립수진흥원 1999). 홍민어는 미국의 캐롤리나주와(Paul A, 1993) 그리고 지중해에서(Diamant, 1998) 새로운 양식대상어종으로서 연구가 되고 있다. (중략)
