Objectives This study was conducted to confirm anatomical information near the treatment areas of visceral chuna manual therapy and to secure stability and effectiveness during the treatment. Methods For 50 healthy adult men and women, a total of 13 ultrasound images were taken of the 7 treatment areas which are the representative treatment areas of visceral Chuna manual therapy. Results The treatment area of the bottom of the liver can be palpated around the right side ST19 and CV14. The treatment area of the gallbladder and the common bile duct can be palpated around the right side SP16 and ST20. The treatment area of the cardia and the pylorus can be palpated around the left side KI21, right side ST20, ST21, KI19, KI20, CV12, and CV13. The origin point of the mesentery root can be moved to the left and lower left from CV12 and can be palpated. The treatment area of the ileocecal valve and the cecum can be palpated around the right side SP14. The treatment area for the colic flexure can be palpated around the both side LR13. The treatment support point for the kidneys can be palpated around both side BL51. Conclusions It is thought that if the ultrasound image data from the meridians around the treatment site is used as an auxiliary, it will be more effective in terms of safety and effectiveness during the treatment of visceral Chuna manual therapy.

Background: Focal adhesion kinase (FAK) and Src are non-receptor tyrosine kinases. FAK and Src play a critical role in inducing malignant transformation in tumor cells. Objectives: We performed immunohistochemical staining for total and phosphorylated forms of FAK and Src, to evaluate the role of FAK and Src in the development of premalignant and malignant skin lesions. Methods: A total of 59 facial skin samples (30 actinic keratoses, 10 Bowen``s diseases, 13 squamous cell carcinomas and six perilesional skins) were immunohistochemically stained for Ki-67, total (t) and phosphorylated (p) form of FAK and Src. Methods: A total of 59 facial skin samples (30 actinic keratoses, 10 Bowen``s diseases, 13 squamous cell carcinomas and six perilesional skins) were immunohistochemically stained for Ki-67, total (t) and phosphorylated (p) form of FAK and Src. Results: Cells positive for t-Src, p-Src-y530, t-FAK and pFAK-s722 were detected in premalignant intra-epithelial lesions (PELs) and squamous cell carcinomas (SCCs), but not in the perilesional skin. There was a tendency towards high correlation between Ki-67 and t-FAK or pFAK-s722, suggestive of the active role of FAK in cell proliferation. Conclusion: Our findings of higher t-Src and p-Src-y530 positive cells in PELs, as compared to SCCs (with higher Ki-67 level), are suggestive of the other role of Src in tumor formation and progression, which requires further investigation.

Purpose: ACR (American College of Radiology) offers variable parameters to PET/CT quality control by using ACR Phantom. ACR Phantom was made to evaluate parameters which are uniformity, attenuation, scatter, contrast and resolution. Manual analysis method wasn't good for the use of QC because values of parameter were changed as it may user and it takes long time to analysis. Ki-Chun Lim, a nuclear scientist in AMC, developed program that automatically analysis values of parameter by using ACR Phantom to overcome above problems. In this study, we evaluated automatic analysis program's usability, through the comparing SUV of each method, reproducibility of SUV when repeated analysis and the time required. Materials and Methods: Using Flangeless Esser PET Phantom, the ideal ratio of 4 : 1 hot cylinder and BKG but it actually showed a ratio of 3.89 to 1 hot cylinder and BKG. SIEMENS Biograph True Point 40 was used in this study. We obtained images using ACR phantom at Fusion WB PET Scan condition (2 min/bed) and 120 kV, 100 mAs CT condition. Using True X method, 3 iterations, 14 subsets, Gaussian filter, FWHM 4 mm and Zoom Factor 1.0, $168{\times}168$ image size. We obtained Max. & Min. SUV and SUV Mean values at Cylinder (8, 12, 16, 25 mm, Air, Bone, Water, BKG) by automatic program and obtained SUV by manual method. After that, we compared manual and automatic method. we estimate the time required from opened the image data to final work sheet was completed. Results: Automatic program always showed same result and same the time required. At 8, 12, 16 and 25 m cylinder, manual method showed 6.69, 3.46, 2.59, 1.24 CV values. The larger cylinder size became, the smaller CV became. In manual method, bone, air, water's CV were over 9.9 except BKG (2.32). Obtained CV of Mean SUV showed BKG was low (0.85) and bone was high (7.52). The time required was 45 second, 882 second respectably. Conclusions: As a result of difference automatic method and manual method, automatic method showed always same result, manual method showed that the smaller hot cylinders became, the lager CV became. Hot cylinders mean region size, the smaller hot cylinder size becomes we had some trouble in doing ROI poison setting. And it means increase in variation of SUV. The Study showed the time required of automatic method was shorten then manual method.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

National Agricultural Pesticide Risk Analysis (NAPRA) World Wide Web (WWW) 시스템(http;l//danpatch.ecn.purdue.edu/∼napra)은 다양한 영농방법에 따른 농약과 영양물질의 지표수/지하수 유실량을 웹에서 모?하고자 개발되었다. 단일 토양에 대해서 모의할 수 있는 Single Field 버전의 많은 기능이 개선되었고, 행정구역/수계 경계에 대해서 모의할 수 있는 County/Watershed 버전을 확장시켜, Web Geographic Information Systems (GIS) 버전의 NAPRA 시스템을 개발하였다. Web GIS 틀을 이용하면, 모의하고자 하는 지역을 마우스로 디지타이징 한 후 그 지역에대해서 영농방법에 따른 영향을 모의할 수 있다. 모의결과를 웹브라우저를 통해서 지도로 보여줄 뿐만 아니라, 그 결과를 데스크탑용 CIS에서 사용할 수 있는 포맷으로 제공한다. 모델을 운영하기 위하여 방대한 양의 입력자료가 필요하고, 일반 사용자가 준비하기 힘든 데이터들이 있는데, NAPRA WWW 시스템은 이러한 입력자료를 서버측 GIS, 데이타 베이스, 강우 및 온도 모델 예측치에서 추출하여 모델을 운영한다. 또한 모의결과를 방대한 양의 텍스트 파일이 아닌, 차트나, 테입블, 또는 지도형태로 보여주기 때문에, 농부와 같이 전문지식이 없는 사람이 이 시스템을 이용하여 여러가지 영농 방법 중에서 환경 친화적이면서 경제성을 유지 할수 있는 최적관리기법을 찾아낼 수 있다.

Stroke is one of the most important diseases in the elderly, but studies on the elderly stroke(age ≥70 years) are rare. The authors evaluated clinical characteristics of ischemic stroke in the elderly and compared them with those in the young(age ≤69). The conclusion obtained are as follows. 1. The strokes with multiple risk factors and combined diseases were more common in the elderly than in the young. 2. Middle cerebral artery territory was most frequently involved in the two groups, but vertebrobasilar territory was more frequently involved in the elderly than in the young. 3. The incidence of recurrent stroke and pathogenesis did not differ significantly between the two groups. 4. Among the complications, urogenital diseases were more common in the elderly than in the young.

The researches of alternative energy are carried out to reduce the dependence of fossil energy in these days. Hydrogen energy, one of the candidates of alternative, is drawing attention due to their environmental compatibility and recyclable ability, and it is most suitable for fuel of fuel cells. Solid oxide fuel cells (SOFC) which is called the fuel cell for next generation have many advantages such as high conversion efficiency, environmental compatibility, modularity, siting flexibility, but its high operating temperature imposes stringent material and processing requirements. For the alternative proposal for those problems, the low temperature ceramic fuel cell using NH4+/H30+ -beta-alumina for electrolyte is being investigated. In this paper, the characterization of low temperature ceramic fuel cell and electrolyte are described.

제약업종 부산물 및 화장품 제조업 폐수처리오니의 고추 비해에 미치는 영향

임동규,이상범,권순익,이승환,소규호,성기석,고문환 한국환경농학회 2004 한국환경농학회지 Vol.23 No.4

본 연구는 퇴비의 원료로 지정된 제약업종 부산물(공정오니) 및 화장품 제조업 폐수처리오니를 시용한 후 고추를 재배하면서 시용한 오니에 의한 작물의 비료의 피해를 밝히기 위해 포장에서 작물의 생육과 수량(적과, 청과), 시기별로 토양 및 식물체 중 중금속 함량 등을 조사하였다. 토양 중 유기물 및 질소성분은 시험재료의 성분함량이 높은 처리구에서 생육 초기(6월 11일)에 높았다. 토양의 중금속 성분에서 전함량의 경우 As성분은 생육 중기(7월 8일)에 함량이 급격히 높아졌다가 감소하였으며 Zn·Cu·Pb·Cd성분은 수확기에 갑자기 함량이 증가하였고, 1 N-HCI 가용함량에서 Zn·Cu·Pb·As성분은 생육 중기에 증가하였다가 감소하는 경향이었다. 고추의 생육(초장, 간경)은 초기에는 오니구(제약오니3구 제외)가 화학비료구보다 전반적으로 불량하였는데 이는 유기물 함량이 높은 미 부숙된 오니의 영향인 것으로 생각되며, 생육 후기에는 회복이 되어서 화장품 오니구를 제외하고는 서로 비슷하였다. 고추 식물체(잎, 줄기)의 질소함량에서 생육 초기 및 중기에 제약오니1과 돈분구가 높은 것은 이들 시험재료의 유기물 및 질소성분의 특성과 함량에 기인된 것으로 보이며, 식물체 중 중금속 함량에서 잎은 Zn·Pb·Ni성분이, 줄기는 Zn·Pb성분이 수확기에 급격히 높아졌으므로 이들 성분에 대해서 주의할 필요가 있다고 생각된다. 고추의 총 적과 수량은 가축분뇨 > 제약오니3 > 제약오니1 > 화학비료 > 제약오니2구 순으로 낮아졌으며, 화장품오니구는 타 처리구보다 상당히 감수하였다. 수확기 고차 청과 및 적과의 중금속 함량은 Zn과 Cu성분이 타 성분들보다 높았고, 처리별로는 청과에서 Zn 및 Ni성분은 제약오니1구가, Pb성분은 제약오니3구가 타 처리구들보다 조금 높아서 유기성 오니를 퇴비원료로 사용할 경우 오니 중의 Zn·Cu·Pb·Ni성분의 특성과 함량이 상당히 중요할 것으로 판단된다. 따라서 퇴비원료로 지정된 오니 중에서 화장품오니와 제약오니2에서 생육 후기부터 수확기에 걸쳐 질소성분의 부족 현상에 의한 생육부진과 낙엽, 어떤 원인인지 알 수 없지만 비해에 의한 수량감소 등의 원인을 앞으로 연구를 통해서 밝힐 필요가 있다고 생각된다. 본 시험의 결과는 퇴비원료로 지정하거나, 지정된 퇴비원료의 사용을 신청할 때 허가할 퇴비원료가 작물에 대해 적합한지 알아보는 방법의 일환으로 활용될 수 있을 것이다. Three sludge types from pharmaceutical byproducts and one sludge type from cosmetic waste-water sludge as raw materials of compost were used in a field based concrete pot (4 m², 2m × 2m) for investigating damage of red pepper cultivation. These sludges and pig manure (1 Mg/10a, dry basis) were incorporated into the upper of clay loam soil prior to transplanting with red pepper. Changes in concentration and properties of heavy metal for both of soil and plant were investigated 4 times during of red pepper growth. Plant height and stem diameter of red pepper in sludge treatments except to Pharmaceutical sludge 3 were poor than those of NPK treatment. This result were regarded as an effect of incompleted decomposition sludge which has a lot of organic matter concentration. Amount of total As was increased rapidly Jul. 8. in soil, total Zn·Cu·Pb·Cd were in harvest time, and 1 N-HCl extractable Zn·Cu·Pb·As were rised at middle stage and then decreased. Amounts of nitrogen in plant (leaf and stem) were high in Phamaceutical Sludge 1 and Pig Manure treatment in early and middle stage because of organic matter and nitrogen concentrations and characteristics. Amounts of Zn, Pb, and Ni in leaf and amount of Zn and Pb in stem were increased in harvest time so that we need to have a concern in detail. Total yield of red pepper was Pig Manure > Phamaceutical Sludge 3 > Phamaceutical Sludge 1 > NPK > Phamaceutical Sludge 2 and Cosmetic Sludge treatment was decreased considerably to compare to others. Amounts of Zn and Cu in green and red pepper in harvest time were higher than the other heavy metals. Finally these results can use to utilize that finding damage on crop for authorization and suitability estimation of raw material of compost.

14종의 새로 합성된 1-(phenoxymethyl)benzotriazole(Ⅰ)(Y=0)과 1-(thiophenoxymethyl)benzotriazole (Ⅱ)(Y=S) 및 1-(azidomethy) benzotriazole(Ⅲ) 유도체의 구조와 in vitro에서 Pyricularia oryzae, Fusarium oxysporum f. sp. sesami, Valsa ceratosperma 및 Botrytis cinerea에 대한 균사 생장을 50% 저해하는 활성(pI_50)사이의 구조-항균활성 상관관계들을 QSAR방법으로 연구하였다. (Ⅰ)의 항균활성은 (Ⅱ)와 (Ⅲ)보다 우세하였으며 phenoxy group(Ⅰ)의 치환기 효과는 수소 결합성 (HB)과 포물선 관계의 electronic effect(σ), steric effect(B_1) 그리고 hydrophobic effect(π)로 설명된다. P. oryzae와 F. axysporum f. sp. sesami의 항균 활성에 대한 치환기의 적정값은 B_1=1.40A, (H)와 σ=0.07∼0.15, (H)이고 V. ceratosperma와 B. cinerea에 대하여는 각각 σ=0.23∼0.28, (C1)과 π=0.70, (C1)이었으며 가장 효과적인 화합물인 (Ia)와 (Id)의 구조-활성관계가 검토되었다 (1990년 5월 11일 접수, 1990년 9월 20일 수리). The structure-antifungal activity correlations between the structure of fourteen new 1-(phenoxymethyl)benzotriazoles (Ⅰ) (Y=0), 1-(thiophenoxymethyl)benzotriazoles (Ⅱ) (Y=S) and 1-(azidomethy)benzotriazole (Ⅲ) derivatives were synthesized, and their activity, fifty percent inhibition of mycelial growth(pI_50), in vitro against Pyricularia oryzae, Fusarium oxysporum f. sp sesami, Valsa ceratosperma and Botrytis cinerea were investigated using a generalized QSAR method. The activity of (Ⅰ) was superior to those of (Ⅱ) and (Ⅲ). The effect of the substituents (Ⅹ) on the phenoxy group (Ⅰ) was rationalized by a parabolic function of electronic (σ), steric (B_1) and hydrophobic parameter(π), and hydrogen bonding (HB). Where the optimal values of substituent on the fungicidal activity againt P. oryzae and F. axysporum f. sp. sesami are B_1=1.40A ; (H) and σ=0.07∼0.15;(H), and those of substituent on the fungicidal activity against V. ceratosperma and B. cinerea are σ=0.23∼0.28; (Cl), π=0.70; (C1), respectively. The most effective compound (Ⅰa) and (Ⅰd) were examined in this study.
