This study was conducted to have basic and applied informations to establish the cultivation method and to improve the cultivation techniques of Angelica gigas Nakai through investigating the rates of germination and seedling establishment with treatment of plant growth regulator and seed priming. The germination rates of round shape seed were about 0.3~12% higher than those of parallel shape. The germination rates with different storage durations were increased at the level of 25oC and 4oC with the storage days, while they were clearly higher at -20oC compared to those at 4oC and 25oC without the storage durations. With the results of germination rates with treating of plant growth regulator and seed priming, their rates with the round shape seeds were comparatively higher about 6% than those with parallel shape seed and they were increased with increasing of the storage durations. The germination rates were generally appeared higher with GA3 than did those with seed priming. The highest germination rate was appeared at 50 ppm GA3 of plant growth regulator and at -0.5 MPa PEG6000 of seed priming. The germination rates?ㅤ ?ㅤ of Angelica gigas were different with different temperature, storage durations and the treatments of plant growth regulator and seed priming. These results could be used according to different cultivating conditions.

In this study, Mechanical property, thermal property, watervapor, and oxygen permeability of biodegradable Soy protein/Pectin-montmorillonite nanocomposite, prepared with Na^(+)-MMT, have been studied. X-ray diffraction and TEM experiments an polymer/silicate composite samples demonstrated that the intercalation of polymer chains leads to increase in the spacing between silicate layers. In addition, it were found that the intercalated Soy protein/Pectin/montmorillonite nanocomposite were prepared. It was found that the addition of only a small of clay was enough to improve the thermal stability and mechanical property of Soy protein/Pectin/montmorillonite nanocomposite. watervapor of Soy protein/Pectin/montmorillonite nanocomposite was generally lower than that of Soy protein/Pectin. oxygen permeability of Soy protein/Pectin/montmorillonite nanocomposite was generally lower than that of Soy protein/Pectin.

Background : Most strains of methicillin-resistant Staphylococcus aureus (MRSA) now exhibit high-level resistance to various antibiotics, such as β -lactam antibiotics, aminoglycosides, macrolides, tetracyclines and quinolones. Recent reports describing the therapeutic failure of vancomycin for MRSA infections have arisen considerable concerns regarding the emergence of MRSA strains, which will require new therapeutic agents. Arbekacin, an aminoglycoside antibiotic, has antibacterial activity against both gram-positive and gram-negative bacteria and is stable in the presence of aminoglycoside inactivating enzymes produced by S. aureus. In this study, we compared the antibacterial activity of arbekacin with those of vancomycin, gentamicin, and amikacin against Staphylococcus aureus (S. aureus) and coagulase-negative staphylococci (CNS). Methods : For a collection of 549 S. aureus and 251 CNS isolates from three Catholic University Hospitals in Korea, minimum inhibitory concentrations (MICs) of arbekacin, vancomycin, amikacin and gentamicin were determined by agar dilution method using Mueller-Hinton agar according to NCCLS (National Committee for Clinical Laboratory Standards, USA)criteria. Results : Among 549 S. aureus isolates, 278 isolates were MRSA and 271 isolates were methicil sensitive S. aureus (MSSA). MIC50 & MIC90 of arbekacin against 549 S. aureus were 0.5 & 1 ㎍/mL, and MIC50 & MIC90 of vancomycin were 1 & 1 ㎍/mL. MIC of arbekacin against 549 S. aureus isolates ranges from 0.03 to 4 ㎍/mL, and MIC of vancomycin against 549 S. aureus ranges from 0.25 to 2 ㎍/mL. MIC90 of amikacin against 549 S. aureus was 32㎍/mL, and that of gentamicin was 128 ㎍/mL. MICs of amikacin and gentamicin were variable, ranging from 0.125 to 256, and otherwise arbekacin and vancomycin revealed relatively narrow range of MICs. MIC90 of arbekacin against 278 MRSA isolates & 271 MSSA were 1 & 0.5 ㎍/mL, and those of vancomycin against MRSA & MSSA were 1 & 1 ㎍/mL. MIC90 of amikacin against 278 MRSA & 271 MSSA isolates were 32 & 4 ㎍/mL, and that of gentamicin against MRSA & MSSA isolates were 128 & 32 ㎍/mL respectively. Among 251 CNS isolates, 122 isolates were MRCNS and 129 were MSCNS. MICSO & MIC90 of arbekacin against 251 CNS isolates were 0.25 & 2 ㎍/mL, and those of vancomycin were 1 & 2 ㎍/mL. MIC of arbekacin against 251 CNS isolates ranges from 0.015 to 32 ㎍/mL, and that of vancomycin isolates ranges from 0.25 to 2 ㎍/mL, MIC90 of arbekacin against 122 MRCNS & 129 MSCNS isolates were 2&0.3 ㎍/ML, and those of vancomycin were 2&s ㎍/ML. MIC90 of amikacin against 251 CNS isolates was 32 ㎍/ML, and that of gentamicin was 128 ㎍/ML for CNS. MIC90 of amikacin against 122 MRCNS & 129 MSCNS isolates were 128 & 8㎍/mL, and those of gentamicin ere 256 & 32 ㎍/mL. Conclusion : Considering above results, arbekacin can be useful agent against most strains of MRSA and MRCMS, which exhibit high-level resistance to amikacin and gentamicin.

Lovastatin(LV), one of the potent cholesterol-lowering agents, is an inactive lactone prodrug which is metabolized to its active open acid (Lovastatin acid. LVA). In order to optimize the assay procedure of LVA by high performance liquid chromatography(HPLC). solid phase extraction(SPE) method and protein precipitation method were employed for the pretreatment of plasma sample containing LV and LVA, and plasma sample was hydrolyzed under alkaline condition to transform all LV to LVA. Following pretreatment of plasma sample. 100ul of sample was injected onto a reversed-phase C_18 column and eluted with a acetonitrile-pH 3.0 phosphate buffer mixture(45:55 v/v) at a flow rate of 2.0ml/min. Ultraviolet detection was carried out at 238nm. It has been shown that all of LV in plasma was converted to LVA in vitro under alkaline condition. On SPE method, elution with acetonitrile-methanol mixture(75:25 v/v) indicated the highest recovery of LVA, but acid treatment of plasma sample before loading on SPE cartridge revealed little effect on recovery of LVA. Compared with two different pretreatment of plasma sample, SPE indicated better sensitivity and recovery.

완전미에 대한 소비자 지불가치 평가

오상헌,이순석,박평식,정호근,이상덕 한국국제농업개발학회 2003 韓國國際農業開發學會誌 Vol.15 No.2

본 분석은 최근 고품질 농산물에 대한 소비자의 관심이 높아가고 있음을 착안하여 서울지역 주부를 대상으로 완전미에 대한 소비자 지불가치를 추정하였다. 가치추정 방법은 다중범위 이산선택 기법을 사용하였으며, 구매유형별 소비자 선호요인을 분석하였다. 또한 추정된 평균값을 근거로 서울지역에서 판매가능한 완전미의 총 소비자 지불가치를 추정하였다. 분석결과를 요약하면 다음과 같다. 1. 완전미에 대한 소비자 선호분석 결과 “구입할 것” 형에서 통계적 유의성을 가지는 변수는 월소득, 교육수준 및 주거형태로 나타나 월소득이 높을수록, 교육수준이 높을수록, 아파트에 거주할수록 완전미 구입의향이 높게 나타났다. “반반이다” 형에서는 주거형태(HOU)가 1% 유의수준에서, 주부의 가구당 월소득(INC), 교육수준(EDU) 및 가구원수(FAM)가 각각 5% 유의수준에서 통계적 유의성이 있는 것으로 분석되었다. 2. 완전미에 대한 소비자의 구매 유형별 평균 지불의사 금액은 일반 쌀보다 최소 1.13배에서 최대 1.55배까지 비싸더라도 구입의사가 있는 것으로 분석되었다. 3. 조사대상 지역인 서울에서 완전미가 전면적으로 판매될 경우 추정 가능한 소비자 지불가치의 총액은 가장 적극적인 구매의향을 나타내는 “반드시 구입” 형은 2.154십억 원, “반반이다” 형은 2.955십억 원으로 추정되었다. 위와 같은 분석 결과는 일반 쌀보다 높은 가격을 지불하더라도 품질이 우수하다면 국산 쌀도 충분히 경쟁할 수 있음을 나타내고 있다. 아울러 최근 연구가 활성화되고 있는 다양한 기능성 쌀에 대해 소비 및 유통 측면에서의 심도 있는 접근이 이루어져야 함을 시사하고 있다고 결론 지을 수 있다. This study aims to estimate the consumers' value of the head rice using the multi bounded discrete choice CVM. The respondents were a total of 1,000 housewives living in Seoul. The results show that householders are willing to pay 3,480won/㎏, 2,920won/㎏ and 2,537won/㎏ for the head rice asuming three scenarios(not sure, sure, definitely). Results also show that in Seoul province the estimate aggregated buying value of the head rice is approximately 2,955 billion won in the definitely scenario.
