Coming with the well-being era, consumer's demand for safe agricultural products is increasing. It is urgent to develop an environment-friendly pear production system. Accordingly, this study was conducted to develop an environment-friendly pear production system by using several environment-friendly agricultural materials which is known to be effective in agricultural production. In the effects of environment-friendly agricultural materials on the soil chemical characteristics in pear orchard, the content of total carbon, organic matter, Ca and Mg increased a little respectively compared with those of 2008, and 2nd treatment showed the highest EC and Mg content in the soil among treatments. The content of leaf N, P and Ca in 2009 decreased compared with those of 2008, while Mg content showed no difference between 2008 and 2009 years. Average pear weight in 2009 was 31g higher than that of 2008 (682g) and 2nd treatment showed the highest pear weight (738g) among treatments. The average sugar content was higher in 2009 (12.6$^{\circ}Bx$) compared with that of 2008 (12.2$^{\circ}Bx$) and the plot of 2nd treatment highest sugar content (12.6$^{\circ}Bx$) among treatments. There were no difference in hunter value of L among treatments, but hunter value of a showed higher 1.62 in 2009 than that of 2008 (3.73). The highest of gumminess and cohesiveness of fruits were obtained from 1st treatment and adhesiveness and chewiness of fruits were obtained from 3rd and 1st treatment respectively. Firmness of fruit increased a little in 2009 compared with that of 2008, while the highest firmness was obtained from 3rd treatment with 1.63kg/5mm$\oint$ among treatments. Phosphate content in the peel of 'Niitaka' pear of fruit skin in 2009 (0.97g/kg) showed 0.06g/kg more content than that of 2008 (0.91g/kg), while the highest content was obtained from 3rd treatment (1.15g/kg). Potassium content in the peel of 'Niitaka' pear in 2009 was 8.20g/kg, which is 0.06g/kg more content than that of 2008 (7.82g/kg) and the highest content was obtained from 1st treatment (8.34g/kg) among treatments. The highest nitrogen content in the flesh of 'Niitaka' pear was obtained from 3rd treatment (4.32mg/g), while it was the lowest in control plot (3.10mg/g). Phosphate content in the flesh of 'Niitaka' pear in 2009 (8.20g/kg) showed 0.06g/kg more content than that of 2008 (7.82g/kg), while the highest content was obtained from 1st treatment (8.34g/kg). There were no difference of the potassium content in the fruit peel of 'Niitaka' pear between years, but 1st treatment showed the highest content (11.81g/kg) among treatments, while the lowest was obtained from the control plot (10.83g/kg). 웰빙시대의 도래와 함께 안전농산물에 대한 국민요구가 커져가고 있으며, 이에 따라 친환경 배 생산체계 개발이 절실한 실정이다. 따라서 본 연구는 최근 효과가 큰 것으로 알려지고 있는 유효미생물제제인 Amo 등을 비롯한 몇가지 친환경농자재를 조합 처리하여 친환경 배 생산체계를 수립코자 2년간 수행한 연구결과를 요약하면 다음과 같다. 1. 친환경농자재 처리에 의한 배과수원의 토양양분의 변화는 T-C, 유기물, Ca 및 Mg 함량은 2008년에 비해 2009년 약간 증가하였으며, 처리 간에는 EC, Ca 및 Mg 함량이 2 처리에서 많은 경향이었다. 2. 엽내 질소 및 인산함량은 2008년에 비해 2009년 각 처리구 모두에서 감소하였다. 칼륨 함량은 2008년 1.93%에 비해 2009년은 2.06%로 증가하였으며, 처리간에는 1처리구가 2.17%로 가장 많았다. 칼슘함량도 2008년에 비해 2009년 각 처리구 모두에서 함량이 감소되었으며, 처리간에는 3처리구가 1.52%로 가장 많았다. 3. 연차간 과실특성을 보면 과중은 2008년 평균 682g에 비해 2009년에는 713g으로 31g이 높았으며, 처리간에는 2처리구가 738g으로 가장 높았다. 과실의 당도함량은 12.2~12.6$^{\circ}Bx$로 2008년 평균 12.2$^{\circ}Bx$에서 2009년 12.6$^{\circ}Bx$로 당도가 증가하였다. 처리간에는 대조구와 2처리구가 12.6$^{\circ}Bx$로 가장 높았다. 4. 과피색의 L값은 연차간 처리구간에 큰 차이가 없었으나, a 값의 경우 2008년 3.73에 비해 2009년에는 5.35로 1.62 높은 경향을 보여 성숙진행이 2009년에 다소 빨랐음을 알 수 있었으며, 처리간에는 2처리구가 4.82로 가장 높았다. 5. 과실 조직의 처리간 응집성 및 점착성은 1처리구가 각각 1.97, 0.14로 가장 높았다. 부착성은 2008년과 비교하여 2009년이 -0.86이 적었으며, 유의성이 인정되었다. 처리간 부착성은 3처리가 -2.58로 가장 높았다. 과실의 경도는 1처리구가 14.4로 가장 높았으며, 씹힘성도 1처리가 1.77로 가장 높았다. 6. 과피의 무기성분 함량 중 인산함량은 2008년 0.91g/kg에 비해 2009년 0.97g/kg으로 0.06g 더 많았으며, 처리간에는 3처리가 1.15g/kg으로 가장 많았다. 칼륨함량은 2008년 7.82g/kg에 비해 2009년 8.20g/kg으로 2009년이 더 많았으며, 처리간에는 1처리가 8.34g/kg으로 가장 많았다. 칼슘은 처리간에는 3처리에서 166.80ppm을 나타내 가장 함량이 높았다. 7. 과육의 질소함량은 처리간에는 3처리가 4.32mg/g으로 가장 함량이 높았다. 인산함량은 2008년 평균 1.59g/kg에 비해 2009년 1.42mg/g로 함량이 적었으며, 처리간에는 1처리, 3처리가 1.68g/kg으로 가장 많았다. 칼륨함량은 년차 간에는 차이가 없었으며, 처리간에는 1처리가 11.81g/kg으로 가장 함량이 많았다. 칼슘함량은 2008년 34.13ppm에서 2009년은 35.10g/kg을 나타내 함량이 증가하였다. 마그네슘 함량은 3처리가 0.93g/kg으로 가장 함량이 높았다.

Typical metal oxide thin films having optical and electrical properties are widely used as inorganic functional materials. Liquid phase deposition(LPD) method, a new low temperature process, has been developed for the several advantages of no vacuum system, low cost, high throughput, and low processing temperature(<$50^{\circ}C$). Silica powder was added to 40wt% hydrofluoro-silicic acid($H_2$SiF\ulcorner) to obtain an immersing solution of silica-saturated hydrofluorosilicic acid solution. Boric acid solution was continuously added in the range from 0 to 0.05M to prepare supersaturated hydrofluorosilicic acid solution. LPD $SiL_2$film was formed with the variation of added amount of $H_2$O. The SiO$_2$thin film could be prepared from hydrofluorosilicic acid by LPD method. The thickness of LPD $_SiO2$film was influenced by the boric acid concentration and added amount of $H_2$O. Silicon in thin film existed as SiF\ulcorner by Raman spectrum.

N/A Objectives: Interstitial penumonia is a major cause of death in scrub typhus but little is known about its pathology and pathogenesis. To study the clinical findings, pathology and pathogenesis of interstitial pneumonia in scrub typhus, we performed this study. Methods: We performed clinical evaluation, laboratory tests, radiological evaluation including high resolution CT and pulmonary function tests in 53 scrub typhus patients. Bronchoalveolar lavage(BAL) and transbronchial lung biopsy(TBLB) were done in patients with interstitial pneumonia and electron microscopic examination and immunofluorescence study including monoclonal antibody against Rickettsia tsutsugamushi were done. Results: 1) Interstitial pneumonia was found in 13(26%) patients. 2) Radiological findings: High-resolution CT showed diffuse ground glass opacity, thickening of bronchovascular bundie and prominent central core of secondary pulmonary lobule with minimal thickening of interlobular septum and there were no findings suggesting vasculitis 3) Cells in HAL fluid: total cell count, (46±9)×104/ml, alveolar macrophage, 68±17%, lymphocyte, 28±15% and neutrophil, 5±3% Pathologic finding(TBLH): 4) Light microscope: interstitial edema with mononuclear cell infiltration, mainly lymphocyte, without any evidence of vasculitis or perivasculitis 5) Immunofluorescence and eletron microscope ' IF study, using anti-Ig G,A,M, anti-Cg, anti-fibrinogen and anti-rickettsial Ab, revealed negative reaction. Electron photomicrograph revealed no rickettsial organism. Conclusion: In interstital pneumonia associated with scrub typhus we noted lymphocytosis in BAL fluid and interstitial inflammation in histopathology without any evidence of vasculitis. Thus vasculitis is not the only main pathology but other mechanism including immunopathogenesis may operate in the pathogenesis of intersititial pneumonia in scrub typhus
