  • Plantlet regeneration from the shoot apex was studied in three different genotypes of the chinese yam (Dioscorea opposita Thunb) cv. Jnagma and Danma, Dunggunma. The effects of plant growth regulators and inorganic salts concentration of the culture medium on bud induction and shoot growth were examined. The combinations of 0.2 mg/L BAP + 0.2mg/L kinetin, 0.01mg/L NAA + 0.2 mg/L kinetin and a single treatment of 0.2mg/L BAP were equally effective for bud and shoot formation from the shoot apices in the three cultivars. Auxin (2,4-D, NAA) treatment enhanced calli formation from the cultured apices. Also, the shoot apices of the cv. Dunggunma produced more callus and buds on the culture medium (MS) containing 0.05mg/L NAA and 0.5-1.0mg/L SAP. Lower salt strength of medium inhibited shoot elongation but did not have much effect on the shoot and bud induction from the shoot apices. These results will be useful to obtain disease-free plants of the Chinese yam.

  • 폐면을 이용한 느타리버섯(Pleurotus ostreatus (Fr.) Quel)의 가을재배에서 배지량에 따른 자실체 수량과 초발이 소요일수에 미치는 영향을 시험한 결과 전 배지 공히 배지량이 증가할수록 수량이 증가되었으며, 그 중 폐면 + 볏짚 (6 : 4, V/V) 혼합처리가 증수특이 가장 컸으며$(10{\sim}22%)$, 폐면단용처리가 입상량간 증수특이 가장 완만하였다$(7{\sim}15%)$. 초발이 소요일수는 입상량이 적을수록 빨랐고, 특히 왕겨혼합처리(5 : 5, V/V) $50\;kg/m^2$가 다소 빠른 경향이었다.

  • The purpose of this study is to understand the required concept in the architectural competition for public library and its application in design process. The research is based on the 27 design guideline of architectural competition for public library from 2009 to 2013 and, as a case study, the project for the Chungcheongnam-do Provincial Library, the prize winner in 2014. Three required concepts; symbolism, function, and sustainability, are categorized through the analysis on the design guideline of 27 competitions and are identified. Symbolism is expressed by landmark forms based on the local characteristics. The function of public library means to provide services to everyone, regardless of age, race, gender, religion etc., as a local community. Sustainability is related to passive architecture for the maintenance and management of buildings. These three concepts for public library applied on the design process of Chungcheongnam-do Provincial Library and design elements in each process are categorized in three concepts. The results shows not only how closely the locality and a user are related, but also the changes in the appearance of a public library as time passed.

  • Eleutherococcus senticosus Maxim. has been successfully used as an oriental medicine for various diseases including allergic disorders. Histamine is a major factor on various allergic responses and it is reported that histamine was released from mast cells by sensitization of allergens. In this study, ethanol extracts from E. senticosus Maxim. were prepared and the composition was analyzed by high performance liquid chromatography. The eleutheroside B as a primary effective component of E. senticosus was contained approximately 225 mg/kg in root bark extracts. The extracts were found to significantly inhibit compound 48/80-induced histamine release form mast cells in dose dependent manner. However the extracts had low cytotoxicity on the mast cells with MTT assay. These results showed that E. senticosus Maxim. extracts may be the effective materials on inflammatory disorders.
