        It is important to interpret the soil chemical properties in order to effectively manage the farmland. This study was conducted to investigate the soil chemical properties of upland soybean field according to the soil series at 32 upland fields located in the parts of Gangwon-do. Soil sampling sites were selected by using the National Statistics DB and KSIS DB that is a soil environment information system provided by the Rural Development Administration. Soil samples were collected from 0~15 cm of top soil before seeding or transplanting, air-dried, passed through a 2 mm sieve, and analyzed for soil pH, EC, organic matter, available phosphorus (P2O5), exchangeable potassium, exchangeable calcium and exchangeable magnesium. The average chemical properties have exceeded the each nutrient optimum range level of RDA, except the organic matter in experimental soil 2015. And despite application of conventional fertilization, each soil series nutrient contents were change respectively. The results of this study suggest that conventional fertilization should be applied based on the analysis about the amount of accumulated nutrient contents in the soil.

        Aplastic anemia is a disease characterized by pancytopenia in the peripheral blood and hypocellular bone marrow with the fatty infiltration. The causes of the acquired aplastic anemia were usually related to drugs and immune-related diseases. A 34-years old man was admitted due to general weakness. He has been going hemodialysis for 2 years because of end stage renal disease (ESRD) due to chronic glomerulonephritis. At admission, laboratory tests showed hemoglobin 6.2 g/dL, hematocrit 18.0 %, WBC 5,710mm (neutrophil 71.8%, lymphocyte 19.1%, monocyte 5.9%), reticulocyte 1.9%, platelet 93,000/mm, Fe 12.8 ug/dL, TIBC 204 ug/dL, ferritin 941.47 ng /ml, haptoglobin 0.72 g/L, vitamin B12 508.17 pmol/L, folate 24 ng/mL, total protein 6.54 g/dL, albumin 3.76 g/dL, Alk. pohsphatase 79 IU/L, AST 30.0 IU/L, ALT 39.7 IU/L, total bilirubin 0.57 mg/dl, BUN 79.4 mg/dl and creatinine 10.18 mg/dl. Peripheral blood smear showed the normocytic normochromic anemia with anisocytosis. Anemia was diagnosed but it was irresponsive to the recombinant human erythropoietin (EPO) and blood transfusion. In the bone marrow aspiration smear were there the hypoplastic myeloid and erythroid precursors. The bone marrow biopsy section showed the hypoplasia of all components (10-20%) and the fatty infiltration. We have experienced one case of the idiopathic aplastic anemia in a patient going through hemodialysis and we just report it with documentary records. 저자들은 혈액 투석 중인 환자에서 약물, 면역계 이상등의 원인을 발견할 수 없었음에도 재생 불량성 빈혈이 발생한 1예를 경험하여 문헌 고찰과 함께 보고하는 바이다.

        본 연구는 유아들이 쌓기놀이에서 수행하는 수학활동 내용과 수학활동에 영향을 미치는 요인을 알아보기 위하여 만 5세 유아들의 쌓기놀이를 문화기술적 연구방법을 통하여 고찰하였다. 연구 결과 유아들은 쌓기놀이에서 분류, 서열, 수세기, 전체와 부분, 측정, 공간과 기하, 패턴 등의 수학 활동을 수행하였다. 쌓기놀이에서 나타난 각각의 수학활동은 상황에 따라 매우 다양하고 복합적인 형태로 나타났다. 유아의 수학활동에 영향을 주는 요인으로는 수학적인 배율로 제작된 놀이감의 특징, 놀이주제, 성별, 또래참여, 교사개입 등으로 나타났다. 본 연구는 쌓기놀이 영역뿐만 아니라 여러 흥미영역에서의 유아수학활동 및 이에 영향을 미치는 요인에 대한 관심과 연구의 필요성을 시사해준다. This study investigated the contents of math activity carried out by young children in block-play and the factors influencing on their math activity through ethnographic research methodology. The study shows that young children conducted various math activities: classification, order, counting, whole and parts, estimation, space and geometry, and pattern. Each one of the math activities was appeared to be diverse and compound in terms of format according to situations. The factors influencing on young children's math activity were the characteristics of block-play materials made out of mathmatical magnification, block-play themes, gender, peers' participation, and teachers' intervention. The results suggest that further research on the contents of math activity conducted by young children and the factors influencing on math activity at the other interest areas as well as the block-play area are needed.

      • 산발성 장형 위선암 환자의 Microsatellite Instability와 병리학적 양상

        조창희,홍유찬,안지현,최경현,이상호,신영명,윤기영,정민정,장희경 고신대학교의과대학 2007 고신대학교 의과대학 학술지 Vol.22 No.2

        Background : Through many researches, microsatellite is expected to be a good diagnositic and prognostic factor in colorectal cancer, endometrial cancer, gastric cancer, and the others. The prevalence of microsatellite instability (MSI) in gastric carcinoma has reported variously, 13~44%. Purpose : We aimed to determine the prevalence of MSI-high and the relationship between MSI and pathological characteristics of sporadic intestinal type adenocarcinoma of stomach. Material and Methods : We analyzed 106 sporadic intestinal type adenocarcinoma specimens excised from patients who were over thirty-five years old to determine the statue of microsatellite by DNA sequencing. The tissues were formalin-fixed and paraffin embedded. DNA were extracted and amplified by polymerase chain reaction (PCR). MSI was determined using five markers recommended by National Cancer Institute (NCI). Specimens were also studied with five patholical factors-differenciation of tumor cells, depth of invasion, lymph node metastasis, vessel invasion, and perineural invasion- to determine pathological state. Result : The microsatellite statue was determined as MSI-High in 5 cases (4.7%), no MSI-low, and MSS (microsatellite stable) in 101 cases (95.3%). Within the frequency, there was no large gap in the distinction of gender in MSI cases, but in MSS cases, there was three-times more cases in male. MSI cases had moderate-to-poor differenciation and trend to invade toward serosa. All MSI cases showed no perineural invasion. But we could not find any statistical significance between MSI and pathological characteristics of sporadic intestinal type adenocarcinoma. Conclusion : Results suggest that MSI can not make any certain pathological significance in sporadic intestinal type adenocarcinoma. Even though less than 5% of sporadic intestinal type adenocarcinoma patients showed MSI, it can be used as a influential prediagnostic factor of gastric cancer. Further study with large scale of cases will be followed to verify these results.

        H. S. KIM, H. J. YOON, J. S. RYU, T. S. KIM. The Three Dimensional Analysis of the Upper Body's Segments of the Elderly during Walking. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 1-15, 2004. The purpose of this study was to investigate the kinematic variables of the upper part of the body for 8 elderly men during walking. For this study, kinematic data were collected using a six-camera (240Hz) Qualisys ProReflex system. The room coordinate system was right-handed and fixed in space, with righted orthogonal segment coordinate systems defined for the head, trunk, and pelvis. Based on a rigid body model, reflective marker triads were attached on the 3 segments. Three-dimensional Cartesian coordinates for each marker were determined at the time of recording using a nonlinear transformation(NLT) technique with ProReflex software (Qualisys, Inc.). Coordinate data were low-pass filtered using a fourth-order Butterworth with cutoff frequency of 6Hz. Three-dimensional angles of the head, trunk, and pelvis segment were determined using a Cardan method. On the basis of each segment angle, angle-angle plot used to estimated the movement coordinations between segments. The conclusions were as follows; (1) During the support phase of walking, the elderly people generally kept their head the flexional and abductional posture. Particularly, the elderly displayed little internal/external rotation. (2) The elderly people showed extensional and external rotation postures in the trunk movement. Particularly, It showed the change from adduction into abduction at the heel contact event of the stance phase. (3) The elderly people showed almost same pelvis movement from the flexion into extension, from the abduction into adduction, and from internal rotation into external rotation at the mid stance and toe off of the stance phase.

        김지열,송호천,양광희,최근희,채기문,범희승,김광윤 대한방사선 방어학회 1994 방사선방어학회지 Vol.19 No.3

        본 연구에서는 마우스에 이미 오염된 방사성스트론튬(Sr-85)을 제거하는데 수용성카이토산이 어느정도 효과가 있는지 알아보고자 하였다. Sr-85를 정맥주사한 경우 주사후 1일째의 체내 잔류량은 72.9 ±5.7%, 5일째는 57.7 ±1.9%, 7일째는 54.2 ±1.4%로 서서히 감소하였으며, Sr-85를 복강내 주사한 경우는 주사후 5일째 54.4 ±1.2%, 15일째 50.6 ±0.8%로 정맥주사에 비해 낮은 잔류량을 보였다(5일째 잔류량의 비교, P<0.05), 0.3% 수용성카이토산을 1회 정맥주사해준 제21군 및 10% 수용성카이토산을 식이중에 섞어 먹인 제5군은 각각의 대조군에 비해 체내 잔류방사능의 차이가 없었으나 (P>0.05), 0.3% 수용성카이토산을 3일간 정맥주사한 제3군과 3% 수용성카이토산을 이틀 간격으로 15일간 복강내 주사한 제6군에서는 각각의 대조군에 비해 낮은 잔류방사능을 보였다. (P<0.01). 결론적으로 수용성카이토산을 연속적으로 정맥투여하거나 복강내 투여하는 경우에는 스트론튬의 골대사촉진 또는 골중의 스트론튬과의 반응등을 통해 그 배출을 촉진시킬 것으로 사료되었다. The aim of the present study was to elucidate the effect of the water soluble chitosans on the removal of contaminated radiostrontium(Sr-85) from the bone of mice. The remaining radioactivities in intravenously injected controls(group 1) were higher than in intraperitoneally injected controls (group 4, P<0.01). The % retention at day 5 were 57.7 ±1.9%, 54.4 ±1.2%, respectively. Single intravenous injection of 0.3% water soluble chitosan and continuous oral ingestion of 10% water soluble chitosan for 15 days were ineffective on the removal of contaminated radiostrontiums. Multiple intravenous or intraperitoneal injections of water soluble chitosan effectively removed contaminated radiostrontiums (P<0.01 vs controls). In conclusion, water soluble chitosan might remove once incorporated radiostrontium from bones of mice. further studies were needed to elucidate the mechanism of the removal.
