  • In Korea, many open-air upper palaeolithic sites are located at the river valley, particularly exposed in gently rotting terrain along the river course. They are situated at an altitude less trail 30 m above present river bottom, and covered with the blankets of slope deposits of several meters in thickness. The purpose of this research is to eluridate depositional and vegetational environment of the alluvial upper palaeolithic Jangheung-ri sites on the basis of analytical properties of grain size population, chronology, palynology, soil chemistry and clay mineralogy and magnetic susceptibility of the Jangheung-ri Quaternary formations. The lithostratograpy of Jangheung-ri sit is subdivided into 3 layers based on the depositional sequence and radiocarbon ages. From bottom to top, they are composed of slope deposits with lower paleosol layers, young fluvial sand and gravel with backswamp organic muds, and upper paleosol layers. The upper paleosol was formed under rather dry climatic condition between each flooding period. Dessication cracks were prevalent in the soil solum which was filled with secondarily minuted fragments due to pedogenetic process. The soil structure shows typical braided-typed cracks in the root part of cracking texture, and more diversified pattern of crackings downward. The young fluvial sand gravel were formed by rather perennial streams after LGM. The main part of organic muds was particularly formed after 15Ka. Local backswamp were flourished with organic muds and graded suspension materials in the flooding muds were intermittently accumulated in the organic muds until ca. 11Ka. This episode was associated with migration of Nam River toward present course. Organic muds were formed in backswamp or local pond. Abies/Picea-Betula with Ranunculaceae, Compositae, Cyperaceae were prevalent. This period is characterized with B$\Phi$lling, Older Dryas, Allerod, and Younger Dryas (MIS-1). Stone artefacts were found in the lower paleosol layers formed as old as 18Ka-22Ka. Based on the artefacts and landscape settings of the Jangheung-ri site, it is presumed that settlement grounds of old people were buried by frequent floodings of old Nam River, the river-beds of which were heavily fluctuated laterally and river-bed erosions were activated from south to north in Jangheung-ri site until the terminal of LGM9ca 17Ka).

  • Lignin degrading enzymes from Lentinula edodes have broad substrate specificities, and therefore can degrade a variety of recalcitrant compounds. In this study, the lignolytic biodegradation was investigated in five different L. edodes fungi (Chunbaegko, Sanjo 303ho, Poongnyunko, Baekhwahyang, and Soohyangko). The fungi were evaluated for their ability to decolorize Remazol Brilliant Blue R (RBBR) in malt extract broth medium. Sanjo 303ho, Poongnyunko, Baekhwahyang, and Soohyangko rapidly decolorized RBBR within 7 days. The activities of manganese peroxidase (MnP) and laccase were determined in the absence and presence of lignin. Poongnyunko displayed the highest ligninolytic activity on day 7 of incubation (2,809 U/mg and 2,230 U/mg for MnP and laccase, respectively).

  • The grade and price of Lentinula edodes largely differs in preference depending on the product area and seasonal factors. The product amount of autumn L. edodes was higher than that of spring L. edodes, but high quality, which is divided into "Hwago" is low in preference. Mostly, the autumn L. edodes is obtained as powder; hence, it is necessary to develop a processing method to utilize its flavor and aroma at an affordable price. Additionally, we estimated the content of 𝛽-glucan, ergosterol, vitamin D2, reducing sugars, and free amino acids and evaluated the anti-inflammatory activity of saccharification powder of log-cultivated L. edodes. In the saccharification powders obtained via 7 min of UV irradiation of log-cultivated L. edodes, 𝛽-glucan and vitamin D2 contents were found to be the highest, whereas ergosterol content was found to be the lowest. The content of reducing sugars ranged from 62.4 mg/L to 68.2 mg/L. The free amino acids were higher in these saccharification powders than in the control. Subsequently, RAW 264.7 cells were treated with different concentrations (10, 50, 100, 200, 300, and 500 ㎍/mL) of the saccharification powders of log-cultivated L. edodes obtained via different UV irradiation time applications. The cells showed good viability; the anti-inflammatory effect was found to be the highest at 7 min UV irradiation. Therefore, 7 min of UV irradiation was determined to be the optimum condition for manufacturing saccharification powders of log-cultivated L. edodes. Hence, saccharification powders of log-cultivated L. edodes may be used as a raw material for natural sweeteners, food additives, and in the food industry.

  • 고병원성조류인플루엔자가 지난 4월 6일 전남 장흥에서 마지막으로 발생한 이후 한달 이상 추가 발생이 없어 종식단계에 접어들었다. 지난해 11월 26일 최초 발생한 고병원성조류인플루엔자는 235일간 가금농장에서 106건, 관상용 2건을 비롯해 야생조류에서 234건이 검출됐고, 이로 인해 487농가에서 3천만수에 육박하는 가금류가 살처분됐다. 이중 오리는 육용오리 96농가 184만9천수, 종오리 23농가 184천수가 살처분됐다. 특히 종오리의 경우 농가수로는 35%가 피해를 입었으며 사육수수로는 4월말 현재 산란종 오리수가 전년대비 17.1%가 줄어들었으며 평년에 비해서는 30% 가까이 줄어들었다. 때문에 당분간 육용오리 생산에 차질이 불가피하며 살처분 농가들의 입식도 늦어질 것으로 예상되고 있다. 이처럼 고병원성조류인플루엔자 발생으로 인해 국내 오리산업은 큰 피해를 입었으며 정상으로 회복하기까지는 상당한 시일이 소요될 것으로 예상된다. 우리나라 뿐만 아니라 전 세계적으로도 고병원성조류인플루엔자로 인해 몸살을 앓고 있다. 아시아는 물론 유럽, 아프리카, 북아메리카까지 고병원성 조류인플루엔자가 지속적으로 발생하고 있기 때문이다. 전 세계적인 고병원성조류인플루엔자 발생은 장기적으로 국내 오리산업에도 악영향을 미칠것으로 예상되고 있다. 원종오리를 수입하고 있는 영국 등에서도 고병원성조류인플루엔자가 발생함에 따라 가금류의 수입이 중단되면서 장기적으로 종오리 수급에도 차질이 예상되기 때문이다. 이에 이번호에서는 앞으로의 종오리 수급 현황 및 전망에 대해 살펴봤다.

  • In Seongju, Gyengsangbuk-do, the Placenta Chamber (胎室, Taesil) of 18 sons and a son of the crown prince of King Sejong(世宗大王) is located in one place. Taesil refers to the place where the umbilical cord and placenta, which are separated when the baby is born, are placed in a jar made of pottery and stone box and then buried on the ground. The placenta chamber in Seongju has the Buncheong ware (粉靑沙器) cover buried on the ground to protect the baby's placenta. These covers are all hemispherical, with a diameter of more the 20cm. The decorations were made using black and white inlaid techniques only on the outside. The Buncheong ware cover with this shape and pattern has been confirmed only in the placenta chamber in Seongju. This study targets 6 of the Buncheong ware cover whose owners were identified, when and where they were prepared, what the stylistic features and meanings are, and where it was produced. The results of the study are as follows. First, ss a result of reviewing the production background and procurement system of this bowl, it was inferred that it was sourced from Jangheunggo (長興庫) at the central government office, between 1436 and 1439, when the event to bury the placenta of royal members in the ground was the most active. Second, it analyzed the unique features of this cover, such as the shape, pattern, and baked traces. The shape and pattern were compared to the ritual objects contained in the Sejong Silok Oryeui (『世宗實錄』 「五禮」, Five Rites of King Sejong Chronicle) and the lid of the royal placenta jar made in the 15th and 16th centuries. Third, this study suggests that the baking method was based on the shape and location of the traces remaining outside the cover. Finally, the following data were used to estimate the production site: the relationship with the 'Jagiso (磁器所, ceramic workshop) registered in the Sejong Silok Jiriji (『世宗實錄』 「地理志」, Geographical Appendix of King Sejong Chronicle); various records of contribution and dedication about the Buncheong ware made here; and the Buncheong ware and related tools excavated from the kiln site in the area. The place where the Buncheong ware cover was produced is estimated to be the most likely production site for the kiln site in Chunghyo-dong Kiln Site, located in Jeolla-do province by synthesizing the data above.
