Objectives : The aim of this study was to compare endogenous plasma lithium concentrations among schizophrenic patients classified by DSM-IV subtype and control groups and to investigate the correlation of endogenous plasma lithium concentration and psychotic symptoms in schizophrenia. Methods : Schizophrenic patients were selected among psychiatric inpatients without lithium medication and then classified by DSM-IV schizophrenia subtype, Schizophrenic patient groups were composed of 15 disorganized type, 15 paranoid type and 15 undilferentiated type schizophrenic patients. The control group was composed of 15 healthy subjects without any psychiatric disease,Endogenous plasma lithium concentrations were estimated by inductively coupled plasma atomic emission spectrometer. The psychotic symptoms in schizophrenic patients were classified as positive symptoms, negative symptoms and disorganized symptoms according to andreasen classificationl about SANS and SAPS items. Endogenous plasma lithium Con-centration among three subtypes of schizophrenia and control group was compared, and correlation between endogenous plasma lithium concentrations and psychotic symptoms was examined. Rcsults : 1) Schizoprenic patients showed higher endogenous plasma lithium concentration than control groups (p=0.033). Endogenous plasma lithium concentrations were significantly different among three subtypes of schizophrenia (p=0.001). Compared with the control group, disorganized type showed higher endogenous plasma lithium concentration, but paranoid type and undifferentiated type were not significantly different. 2) Disorganized symptoms correlated with endogenous plasma lithium concentration (r=0.416, P=0.004), but negative symptom and positive symptom did not significantly correlate with endogenous plasma lithium concentration (r=0.202, P=0.184. r= -0.216, P=0.155). Conclusion : These results suggested that schizophrenic patients with disorganized symptom show the differences in utilization or distribution of endogenous lithium.

조남석,정홍채,김동훈,이상선,Ohga, Shoji,Leonowicz, A. 한국목재공학회 2004 목재공학 Vol.32 No.1

표고버섯(Lentinula edodes)의 생장이 매우 좋았던 일본잎갈나무재의 수용성 추출물(water-soluble fraction, WSF)을 분리하여 구성당을 분석한 결과, rhamnose 및 mannose는 거의 없고, glucose도 2.2%로 매우 낮았으며, arabinose가 18.3%, galactose가 75.3%로서 가장 많이 함유되어 있었다. 정제된 추출물의 arabinose와 galactose의 함량비는 1 : 3.4였다. 정제된 WSF를 완전메틸화·가수분해·가스크로마토그래피에 의하여 분석한 결과, β-1,3 결합한 D-galactopyranose가 주쇄를 이루며, 이에 galactose의 C6위에 측쇄로서 β-1,6 결합한 D-galactose와, β-1,6 결합한 L-arabinose가 존재하며, 전자는 2-3개의 D-galactopyranose가 결합을 하고 있고, 후자는 L-arabinofuranose가 1-2개 중간의 측쇄구조를 이루고, 말단은 L-arabinopyranose로 구성되어 있었다. PDA배지에 WSF첨가로 표고의 균사 생장이 매우 증진되었으며, 2-4% 첨가수준에서 균사 생장이 최대였고, 첨가량이 더 많으면 균사의 생장이 오히려 감소되었다. 톱밥배지에서도 PDA 배지에서의 결과와 마찬가지로 WSF첨가로 균사 생장이 증진되었으며, 산림 6호 및 Mok-H의 경우 모두 4% 첨가에서 균사의 생장이 최대로 나타났다. 톱밥배지에 WSF 첨가가 버섯생산량을 증가시켰는바, Mok-H의 경우 무첨가에 비해 약 1.3배, 산림 6호의경우 1.2배 증수되었다. 버섯균 세포벽의 주성분인 ergosterol 함량변화를 측정한 결과, WSF첨가로 미첨가에 비하여 ergosterol의 함량이 증가하였으며, 균사가 콜로니를 형성하는 초기단계에서는 낮은 ergosterol함량을 나타냈으나 자실체가 형성되는 시기에 급격히 높아지는 결과를 나타냈다. 따라서 배지내의 ergosterol함량이 자실체형성의 주요 예측수단으로 이용될 수 있을 것으로 판단된다. The water soluble fractions(WSF) from Japanese larch wood were isolated, purified by anion exchange resin and Sephadex gel filtration and identified its chemical structure by means of periodate oxidation and methylation reactions. Its major components are arabinose and galactose (1 : 3.4). Based on the results of periodate oxidation, methylation and gas chromatographic analysis of purified WSF, main chain is composed of β-1.3-glycosidic linkage among D-galactopyranoses, and two different side chains; β -1,6-glycosidic linkage among 2-3 units of D-galactopyranoses and β-1,6-glycosidic linkage between 1-2 units of Dgalactopyranose and L-arabinopyranose. Addition of WSF to culture media of oak mushroom (Lentinulu edodes) accelerated the mycelial growth. In the case of PDA cultures, 2 percent addition of WSF in Sanlim No. 6 strain and 4 percent of WSF in Mok-H strain mostly enhanced the mycelial growth of the mushroom. In the case of sawdust cultures, 4 percent addition of WSF in two strains showed the best mycelial growth. High percentages addition of WSF inhibited mycelial growth of the mushroom. Mushroom production was increased with addition of WSF. By the addition of WSF, ergosterol contents in the media were quite high at the colonized stage and rapidly increased at the fruiting stage. Therefore the ergosterol content could be utilized as an indicator to evaluate the culture maturity for the mushroom fruiting.

김남천,이시진,신항식,송영채 한국유기성폐기물자원화협의회 1993 유기성폐기물자원화 Vol.1 No.2

본 연구에서는 우리나라의 동물성 생지방의 발생 실태 및 유통현황에 대해서 조사, 분석하여 제반 문제점을 파악하고 적절한 유통근대화 방안을 제시하였으며, 생지방이 환경에 미치는 영향 등에 대한 연구를 종합적으로 수행하여 최종처리, 재활용 등 효과적인 관리대책을 제시하고자 하였다. 생지방의 발생원은 전국에 산재한 170여개의 도축장과 280여개의 육가공공장을 비롯한 식육점, 음식점 등으로서 식육의 모든 유통과정과 관련성이 크며, 수도권에만 60%이상의 발생원이 집중되어 있는 것으로 밝혀졌다. 현재 전국에서 발생되는 생지방의 1일 발생량은 약 650-750여톤으로 300여명의 수집원이 손수레, 자전거, 오토바이 등의 낙후된 수거 장비를 등원하여 수거하고있으며, 약 60여개에 이르는 수집상은 수집원으로 부터 생지방을 매입하여 재활용 공장으로 운송하고 있다. 그러나, 유통업계의 현실은 영세성과 전근대적인 경영방법, 거래형태의 무질서등의 문제점을 내포하고 있으며, 결국 유통체계의 혼란을 야기시켜 정상적인 생지방 재활용업계의 발전을 저해하고 있어 적절한 관리 및 유통구조의 근대화를 위한 행정적인 지원 및 제도적인 장치가 필요한 것으로 사료된다. 유통구조의 근대화 방안으르 효율적인 유통경로가 제시되었으며 유통산업의 대형화, 계열화 등을 통하여 수거효율의 향상과 유통마진율의 절감효과를 얻을 수 있는 것으로 분석되었다. In this study, generation characteristics and distribution situation of the animal fat residue were investigated to identify it's management problems and to propose alternatives for the recycling and final disposal. Generation sources were the meat distribution net-work including about 170 slaughterhouses, 280 meat-packing plants. thousands of meat shops and restaurants etc. The daily total amount of the animal fat residue is about 700 ton/day. More than 60% of the generation sources were concentrated in Seoul metropolitan area. The residue was collected by about 300 men using old-fashioned devices like handcarts, bike and auto bike, transported to the recycling plants by about 60 collection agencies. The residue was processed to produce by-products such as grease, tallow, animal feed ingredient in the recycling plants. At present, however, a great number of unlicensed, and mostly small rendering processors without having pollution control facilities do the unlawful business. These small, old fashioned and unorganized businesses are creating environmental problems by disposing the waste in improper ways such as open burning and dump. Improvement of the distribution network, the large-scale plants, and the estabilishing proper infrastructures were suggested to overcome the problems for the sound fat residues reprocessing industry.

Development of Fault Location Algorithm and Its Verification Experiments for HVDC Submarine Cables

Chae-Kyun Jung,Hung-Sok Park,Ji-Won Kang,Xinheng Wang,Yong-Kab Kim,Jong-Beom Lee 대한전기학회 2012 Journal of Electrical Engineering & Technology Vol.7 No.6

A new fault location algorithm based on stationary wavelet transform and its verification experiment results are described for HVDC submarine cables in this paper. For wavelet based fault location algorithm, firstly, 4th level approximation coefficients decomposed by wavelet transform function are superimposed by correlation, then the distance to the fault point is calculated by time delay between the first incident signal and the second reflected signal. For the verification of this algorithm, the real experiments based on various fault conditions and return types of fault current are performed at HVDC submarine cable test yard located in KEPCO(Korea Electric Power Corporation) Power Testing Center of South Korea. It proves that the fault location method proposed in this paper is very simple but very quick and accurate for HVDC submarine cable fault location.
