본 연구는 perlite를 이용한 오이의 양액재배시 적정 배지량과 근권용적을 구명하고자 용기의 크기가 2, 4, 6, 8 및 10ℓ인 플라스틱 포트에 펄라이트를 채워 오이를 양액재배하였다. 근권용적이 증가할수록 초장, 경경, 엽수 및 엽면적이 증가하였고, 과실수와 과실중량에서는 근권용적이 큰 8ℓ와 10ℓ의 처리구에서 가장 양호하였으며 기형과 발생률도 낮은 경향이었다. 근권용적 6ℓ이상으로 하였을 때 경으로의 건물분배가 줄어들고 엽으로의 건물분배가 많았다. NAR과 CGR은 근권용적이 증가함에 따라 증가하는 경향을 보였다. 근권용적에 관계없이 본 실험 범위내에서는 LAI가 증가할수록 NAR과 CGR도 증가하는 경향을 나타내었다. This experiment was carried out to investigate the effect of container size and substrate volume on the growth and fruit yield of hydroponically grown cucumber(Cucumis sativus L.) plant. Seeds were sown in plug tray filled with coir dust on Feb. 13, 1998. Seedlings with 5 to 6 true leaves were transplanted in 2l, 4l, 6l, 8l and 10l plastic pots filled with perlite medium. Cucumber fruits were harvested with 1 to 2 day interval, and fresh weight, number and malform of fruit were recorded. Plant height, stem diameter, number of leaves and leaf area highly depended on the container size. Total fresh weight and the number of fruit were increased as the container size increased. NAR(net assimilation rate) and CGR(crop growth rate) increased with increasing the container size. Optimum container size for hydroponically grown cucumber plant using perlite medium was recommended as 8l per plant.

정순주,박순기,이범선,김월수 全南大學校 農業科學技術硏究所 1998 農業科學技術硏究 Vol.33 No.-

배지종류가 멜론의 생육 및 과실품질에 미치는 영향을 구명하고자 코리아멜론을 이용하여 시설내에서 재배하여 실험한 바 다음과 같은 결과를 얻었다. 토경, 펄라이트경 및 토양격리상에 재배한 경우 생육전반기에는 초장, 엽면적, 각 기관별 생체중 및 건물중 등에서 펄라이트경과 토양격리상이 토경 멜론보다 좋았다. 토양, 왕겨 혼합배지 및 토양·펄라이트·피트모스 혼합배지(360ℓ:180ℓ:60ℓ)에 재배한 경우 생육초기에는 왕겨 혼합배지와 토양·펄라이트·피트모스 혼합배지에서 조사전체 항목에 걸쳐 생육이 양호하였다. 토경, 펄라이트경 및 토양격리상에 재배한 멜론의 과실품질을 보면 과중은 토경보다 처리구가 높았고 당도는 펄라이트경에서 13.3도로 가장 높았다. 산도는 펄라이트경에서 낮게 나타났다. 토양에 왕겨, 펄라이트 및 피트모스를 혼합하여 재배한 멜론의 과실품질를 보면 토양·왕겨 혼합배지에서 당도가 12.4도로 가장 높았고 과중은 토양에 펄라이트와 피트모스를 혼합한 경우가 높았다. The experiment was carried out to investigate the effects of substrates on the growth and fruit quality of the Korea melon (Cucumis melo L. var. reticulatus). Seedlings were grown in soil(not isolated) and polyethylene boxes (10mX50cmX12cm, vol. 600l) filled with perlite, SI (isolated soil culture), RHS [rice hull (200l)+soil (400l)], SP-1 (soil : perlite : peatmoss = 360l : 180l : 60l), SP-2 (soil : perlite : peatmoss = 300l : 225l : 75l), respectively. Plant height, leaf area, fresh and dry weights were higher in perlite culture and isolated soil culture than those of soil culture at the beginning of growth. The vegetative growth of melon in RHS and SP-1 were better than that of soil culture. Soluble solid content and fruit fresh weight were higher in perlite and SI culture than those of soil culture. In the case of mixing substrates, soluble solid content was higher in SP-1 than that of the other substrates. The isolated soil culture of mixing perlite, peat, and soil were recommended as substrate for hydroponically grown melon.

본 연구는 양액재배를 이용한 국화의 절화재배시 적절한 재배시스템과 적정 pH수준 구명을 통한 고품질 절화국화의 다수와 생산기간을 단축을 목적으로 재배시스템의 종류와 pH변화가 국화의 생장과 절화품질에 미치는 영향을 구명하고자 실시하였다. 재배시스템은 분무경, 박막수경, 코코피트경 및 펄라이트경을 공시하였고, pH는 5.0, 5.5, 6.0, 6.5 및 7.0으로 처리하여 처리별 생장특성과 절화품질을 비교하였다. 생장 기간이 경과함에 따라 고형배지경인 코코피트경과 펄라이트경에서 자란 국화가 비고형배 지경인 분무경과 박막수경에서 자란 국화보다 초장, 경경, 엽수, 엽면적, 생체중 그리고 건물중 생장이 우수하였는데, 코코피트경에서 자란 절화국화가 특히 높았다. 박막수경에서 재배된 국화 뿌리는 근권의 산소부족, 온도와 pH의 변화 및 병해로 인해 뿌리가 갈변하고 로제트현상을 보였다. 고품질 절화국화는 코코피트를 이용한 고형배지에서 생산할 수 있었는데, 이는 다른 시스템에 비하여 근권온도, EC 및 pH 변화폭이 더 좁았으며 전 생육기간을 통해 보다 안정적이었다. pH변화에 따른 국화의 생장은 거의 차이가 없었지만, 초장을 pH 6.0에서 높았고 경경, 엽수, 엽면적, 생체중 그리고 건물중에서는 pH 6.5에서 높았으며, pH5.0일 때 가장 낮았다. 생육기간 동안 pH변화를 보면 pH 5.0과 pH 5.5에서는 조정한 이후 시간이 경과함에 따라 pH가 높아졌으며, pH 6.0은 변화폭이 적게 나타났으나, pH 6.5와 pH 7.0은 점점 감소하다가 다시 증가하였다. 본 실험의 결과로 보아 고품질 절화의 다수와 생산기간 단축을 기대하기 위해서는 코코피트경에서 pH는 6.0 내지 6.5로 관리하는 것이 적절한 것으로 확인되었다. This study was carried out to investigate the effect of hydroponic systems and pH change of nutrient solution on the growth and flower quality of cut chrysanthemum. Hydroponic systems were aeroponics and NFT as nonaggregate system and cocopeat culture, and perlite culture as aggregate system. pH was adjusted to 5.0, 5.5, 6.0, 6.5, and 7.0. Growth characteristics in terms of plant height, stem diameter, number of leaves, leaf area, fresh weight, and dry weight showed large differences among hydroponic system. Chrysanthemums grown on aggregate culture such as cocopeat and perlite culture system showed better growth than that of nonaggregate culture system such as aeroponics and NFT. Especially chrysanthemums grown on cocopeat culture system were the best of all the treated systems. High quality cut flower of chrysanthemum could be obtained in the cocopeat culture system due to the stabilization of root-zone environment such as EC, pH, and temperature. In the treatment of pH change, plant height was higher in the treatment with pH 6.0 but stem diameter, number of leaves, leaf area, fresh weight, and dry weight were higher in the treatment with pH 6.5. These results demonstrated that shortening of growth period and harvesting of high quality cut chrysanthemum could be obtained from cocopeat culture system with adjusting pH 6.0 to 6.5.

Both genetic and environmental factors play important roles in the pathogenesis of Parkinson Disease (PD). The contribution of many environmental factors including dietary factor remains unproven. The purpose the study was to investigate the dietary habits, nutrient intake and dietary quality of Korean PD patients according to the duration of disease. PD patients were recruited from K and S university hospitals from May 2005 to January 2006. This study was carried out after approval by the Institute Review Board (IRB). British Brain Bank criteria was used to diagnose PD. The subjects were classified into 2 groups based on the duration of PD: < 25 months and ≥ 25 months groups. General characteristics, anthropometric measurements, food habits and dietary intakes were investigated. The results of this study were as follows: 1) The mean age of < 25 months group (66.9 ± 8.0 yr) was significantly higher than that of ≥ 25 months group (62.2 ± 8.8 yr) (p < 0.05). No significant differences were found for academic background, occupation, living status and social activity, however, numbers of diseases, exercise and family history of PD were significantly different. 2) Anthropometric measurements were not different between the two groups. 3) The frequency of taking snacks was significantly higher in < 25 months group and the amounts of alcohol consumption were significantly higher in ≥ 25 months group. 4) Daily intakes of most nutrients were very low compared with DRI. 5) The MAR score was significantly lower in < 25 months group (p < 0.05;) however, the scores of DVS, DDS and DQI were not significantly different. As a conclusion an overall nutrient intake and dietary quality of the Parkinson's Disease patients need to be improved regardless of duration of the disease and a well-balanced diet should be emphasized.

무화과의 암면 양액재배를 통하여 시설재배의 가능성을 검토하고 배지종류 및 품종에 따른 과실생육 및 수량을 검토하여 우리나라 기후에 가장 알맞는 품종을 선발하고 육성을 도모하기 위하여 수행하였다. 봉래시 품종을 4종류의 배지(펄라이트, 코코피트, 암면슬라브 및 입상암면)에 재식하고, 또한 '마쓰이도후인', '봉래시', '화이트제노아' 및 '브라운터어키' 품종을 본엽 4∼5매인 5월 17일에 암면슬라브에 각각 15주씩 정식하여 생장반응과 총수량 등을 조사한바 배지종류에 따른 봉래시 품종의 생장반응은 암면과 입상암면 배지에서 초장, 엽수, 엽장 및 측지수가 다른 배지보다 높게 나타나 이들 두가지 배지의 이용 가능성이 컸고, 암면을 사용하여 재배한 경우 초기 생장은 봉래시 품종이 좋았으나 과실의 수량면에서 단위면적당 총수량과 주당 평균수량은 마쓰이도후인>브라운터어키>봉래시, 화이트제노아 순으로 많았고, 과실 한개당 평균무게, 과장 및 과폭은 브라운터어키 품종이 가장 높았다. 우리나라 남부지역에서 시설내 양액재배에 가장 적당한 품종은 마쓰이도후인 품종과 브라운터어키 품종으로 추천되었다. This experiment was carried out to know the effect of cultivars and substrates on the growth and development of fig tree (Ficus carica L.) grown in hydroponics. Four cultivars ; Masui Dauphine, Bongraeshi, White Genoa and Brown Turkey, were used and four substrates, perlite, cocopeat, rockwool and granular rockwool were employed. Every cultivars cutted into 20cm with two buds on 27th, of February and then inserted into fockwool cube for root initiation, Every fifteen cuttings were transplanted on 17th of May in each substrate. Among cultivars 'Bongraeshi' showed highest growth in terms of plant height, number of leaves and shoots, and leaf length in the both rockwool and granular rockwool. Total yields per square meter and average yields per plant were higher in the order of Masui Dauphine > Brown Turkey > Bongraesh and White Genoa. Brown Turkey showed the heavier frjuit weight and larger fruit length and width than those of the other cultivars. Consequently, optimum cultivars and substradtes for hydroponics were recommended as Masui Dauphine and Brown Turkey, and rockwool and granular rockwool. However further trials would be followed as to the nutrient concentration, composition and solution managemint for improving fruit yield and quality of fig tree during growing period.

Tsutsugamushi disease is an acute febrile illness caused by Orientie. tsutsugsmushi. It is characterized by fever, myalgia, lymphadenopathy, and rash. And it can be easily diagnosed by characteristic eschar and serologic testing. Nearly all of the patients with tsutsugamushi disease improve with antibiotics such as doxycycline. However, the fatality rate of untreated cases is seven to ten percent. Splenic infarction is not common disease which is caused by occlusion of the main splenic artery or any of its branches. It is mainly caused by emboli that arise from cardiovascular disease, but sometimes by regional thrombosis associated with leukemia, myeloproliferative disorder, sickle cell anemia, pancreatitis, splenic torsion and septicemia. We experienced one case of tsutsugamushi disease with splenic infarction, which was improved after doxycycline treatment finished.
