동적 재구성 가능한 하드웨어 구조를 포함하는 시스템은 실시간으로 알고리즘을 처리할 수 있도록 하드웨어 자원을 효과적으로 이용할 수 있어야 한다. 이런 시스템의 수행 성능은 기본적으로 HW/SW 분할 문제에 의존한다. 이 논문은 동적 재구성 가능한 하드웨어를 위한 새로운 HW/SW 분할 알고리즘을 제안했다. 알고리즘은 초기해 얻기 후 그 해를 다시 최적화하는 단계적인 접근방법이다. 알고리즘은 분할 과정에서 FPGA를 재구성하는 과정을 고려했고 이를 최적화하기 위해서 부분적인 재구성(partial reconfiguration) 방법과 prefetching 재구성 방법을 사용했다. 이 휴리스틱(heuristic) 알고리즘을 통하여 JPEG 부호화기가 다른 접근 방법에 비하여 최적의 수행 성능을 얻음을 보였다.

This study intended, through some basic healths test, to find out the body composition, the blood components, and the immune function of the obese high-school girls. With 2 groups of 16 subjects, the eight obese group and the other eight non-obese group, the results are following: 1. In the body composition analysis, its quantity comparison indicates that the obese group shows significance higher than the non-obese group in Body fat and Weight (p<.001). The rate of comparison per weight of body composition tells that the former shows significance lower than the latter in every item(% Water, % Protein, % Muscle, % LBM) except the item % Mineral. (p<.001) 2. In the biochemical serum test, there is much higher significance of the obese group than the non-obese group in TC and TG (p<01), but there is not any significance difference in HDL-C. 3. In the blood test, the significance difference of the obese group is much higher in RBC, Hct, PLT(p<.01) and Hb(p<.05), but not in WBC. 4. In the leucocyte test(WBC diff) to find out their immune function, the obese group shows lower significance difference than the non-obese group only in Monocyte and Eosinophil.(p<.05), but not in Neutrophil, Lympocyte and Bosophil. From the above results, the obese high-school girls seem to have a good nutrient status and show no abnormality in their body composition and blood elements. But the result of WBC diff cannot show clearly the difference between two groups, which tells the need of the further investigation on T-cells and B-cells in lymphocyte.

마가루를 첨가한 식빵을 만들기 위해 물의 양과 마 가루의 양을 달리해서 제조하여 식빵의 수분함량과 Texture특성을 측정하고 또한 마 가루의 아미노산 함량과 식이 섬유소 함량 및 일반적인 성분을 분석하였다. Baker's Percentage사용법에 의해 마가루 첨가함량에 따른 적절한 물의 함량을 구하여 밀가루 100% 기준에 물의 양을 62%, 65%로 차이를 주어 제조하여 빵의 품질특성을 측정한 결과 마 가루 5% 첨가시에는 물의 양 62%가 적당하고, 10%, 15% 마첨가시에는 물의 양이 65%가 적당하였다. Texture특성에서 경도는 65%물을 첨가한 대조군이 가장 낮은 값을 보였으며 마가루의 첨가량이 증가할수록 경도와 검성, 씹힘성은 대조군에 비해 2∼ 3배의 높은 값을 보였다. To make bread added with Dioscorea Japonica Flour, we made bread with different water and Dioscorea Japonica Flour content, and estimated water contained quantity in bread and texture property. And we also analysis content of amino acids and dietary fiber and general composition. To get adequate water content according to adding Dioscorea Japaponica Flour, we made bread with 62% and 65% water content based on 100% wheat flour content of Baker's percentage method. When 5% Dioscorea Japonica Flour was added, 62% water content was appropriate and when 10% or 15% Dioscorea Japonica Flour was added, 65% was better, From a texture characteristic point of view, 65% water control group had the lowest hardness. And according to adding Dioscorea Japonica Flour, springness, gumminess and chewiness increased to 2 or 3 times of 62% water control group.

제주도 감귤원 토양의 화학적 특성과 물 분산성 콜로이드 함량

오상실,현해남,정종배 한국환경농학회 2002 한국환경농학회지 Vol.21 No.2

토양 중에서 농약을 대공극과 숨골을 통하여 지하수로 이동시킬 수 있는 매체로 작용하는 물분산성 콜로이드 함량과 그 안정성은 여러 가지 토양의 이화학적 특성에 의해 결정된다. 본 연구에서는 제주도 감귤원에서 채취한 30개 토양을 사용하여 pH, 유기물, oxalate 용액 추출성 Al과 Fe 등이 물분산성 콜로이드의 함량에 미치는 영향을 조사하였다. 토양의 pH가 증가할수록 물분산성 콜로이드의 함량이 높았으며, pH 5~6 이상의 토양에서는 표면 음전하의 증가에 따라 콜로이드의 안정성이 높아질 가능성이 많은 것으로 나타났다. 낮은 pH 조건에서는 표면 음전하의 감소와 함께 활성 Al 또는 Fe 함량이 증가함에 따라 콜로이드의 응집 현상이 촉진되는 것으로 나타났다. 물분산성 콜로이드의 함량은 콜로이드의 입단화를 촉진시킬 수 있는 토양의 유기물 함량과 반비례하였으며, 유기탄소 함량 5% 이하의 토양에서 특히 물분산성 콜로이드의 함량이 많게 나타날 가능성이 높은 것으로 나타났다. Oxalate 용액 추출성 Al과 Fe의 산화물 또는 수산화물들 그리고 Al의 유기물 복합체는 토양 중에서 콜로이드 형태로 존재할 수도 있으나 점토광물의 입단화를 촉진시키는 결합제로 작용함으로써 물분산성 콜로이드의 분산을 억제하는 것으로 판단되었다. Water-dispersible colloids are suspected to facilitate transport of contaminants to groundwater. This study evaluated some soil chemical properties in relation to the stability of colloids in soils of Jeju citrus orchards. Thirty surface soil samples were collected, and pH, organic matter content, oxalate-extractable Al and Fe contents, and water-dispersible colloid content were measured. In soils of higher pH, water-dispersible colloid contents were higher. The stability of colloids was found to be significantly promoted at pH above 5~6. Since organic matter can act as a flocculant, organic matter content significantly enhanced the colloid stability. In soils of less than 5% organic C, water-dispersible colloid content was expected to be significantly higher. In soils of higher oxalate-extractable Al and Fe contents, colloids remaining in suspension were lower. This indicated that amorphous oxides and hydroxides play important stabilizing roles in soil structure and can stabilize soil clay against dispersion. Therefore in soils of higher pH, lower organic matter, and lower amorphous clay minerals, the stability of water-dispersible colloids and the potential of colloid-mediated transport of organic chemicals to groundwater could be higher.

This is one of the preliminary researches for preventing osteoporosis in women of before and after menopause. We examined 63 women of 46-60 age(1-3 grade students' mothers of P highschool in Pusan) in order to check the standard of primary factors and prevention about osteoporosis by analyzing the questionary which was written by them. As a result, we got the relationship among RF(Risk Factor), PF(Prevention Factor), Age and BMI of osteoporosis is as follows : 1. The relationship between PF and RF was-0..315 and R^2=0.100 at the properness exam of the model. 2. The relationship between BMI and RF was low as 0.076 and R^2=0.006 at the properness exam of the model. 3. The relationship between Age and RF was 0.226 and R^2=0.051 at the properness exam of the model. 4. The relationship between BMI and PF was low as 0.015 and the result of the properness exam of the model got no meaning as 0.000. 5. The relationship between Age and PF was -0.13 and R^2=0.017 at the properness exam of the model. 6. The relationship between Age and BMI was 0.233 and R^2=0.054 at the properness exam of the model. The above facts are presumed as the result of the questionary which has sample size and low distinction. So if these problems are improved in the next study, more meaningful result can be obtained.

Objective : To investigate the pathogenesis of anemia and serum protein alteration in patient with pressure ulcer and proper management method. Method : Eleven patients with pressure ulcer were investigated. To investigate the change of anemia and serum protein between pre- and post-treatment of pressure ulcer, we measured hemoglobin, hematocrit, serum iron, ferritin, transferrin, mean corpuscular volume(MCV), red cell count, serum albumin and globulin before and after healing of pressure ulcer. Result : There was significant increases of hemoglobin, hematocrit, red cell count, MCV, serum iron, ferrtin and transferrin after healing of pressure ulcer(p<0.05). The serum ablumin and A/G ratio were increased significantly(p<0.05). The total globulin and α1-globulin were decreased significantly(p<0.05). There was no statically significant relationship between the ulcer size and the degree of anemia and hypoalbuminemia. Conclusion : This research suggested that anemia and serum protein alteration in patient with pressure ulcer are thought result from chronic inflammatory process. So, anemia and alteration of protein does not require any treatment such as transfusion, iron and albumin supply.

feficotorfer fyf☞ri(Hp)가 위암파 관련이 있다는 역학적인 증거는 많이 있지만 이에 대한 정확한 기전에 대해선 밝혀져 있지 않고 있으며 실험동물 모델도 적절하지 못한 것으로 알려져있다. 본 실험에서는 위암의 원인으로 알려져 있는 f, fyforf'(Hp)를 이용하여 마우스에서 위암 모델을 확립하고 만성염증과정 중에 생성되는 리0와 COX-2 등의 발현이 위암발생에 미치는 명향을 통하여 예방과 치료를 위한 점근을 시도하고자 하였다. 마우스를 7군으로 나누어서 1, 2, 3, 4군의 등물은 MNU를 증류수에 200ppm 농도로 음수병득 이용하띤 10주간 격주로 투여하였으며 MHU 음술 투여 1주 휴씩 후 배양한 f. fyrofi 를 약 109cru/rfll 로 맞춰 한 마리당 0.1ml 씩 이틀 간격으로 세 번에 걸쳐 하룻방 금식시킨 1, 2, 3, 5, 6, 7군기 마우스의 위장에 투입하떴다. 균 투입을 마친 후 다응 날부터 2군쏙 6군은 iNOS 억제제인 aminoguanidine(AG)을 음수병으로 툰여하였으며 3군과 7군은 COX-2 척제제인 nimesulide(NSD)를 투여하였다. 위의 종양발생양상을 샅최보면 bfNU와 Hp만을 투여한 1 관 ; (hfNU +Hp), 2군 : iNO을 inhibitor 투여군(MNU+HP+AG'1. 3군 ;CO딘-2 Inilibitor 투여군(MNU누Hp누 NSD), 4군 ,MNlf 단독투여군, 5군 ;Hp 단독투여춘, 6군 ; 러p 단독에 AG투여군, 7군 , Hp 단독에 NSD투여군의 종양발샐을은 각각 쁜.Bff(l1/16), 70.6%f12/ti), 했.9ff(7/18), 10%(1/10), Off(O/IS)0%(O/S), 0%(O/5)의 발쟁율을 보여 iNOS 억제제인 AC은 좁양발생을 억계하지 못하였으며, COX-2억제제인 NSD 는 종양발생을 유의적으로 감소시켰다. 콩양발생개수에서는 2.62±0.36, 1.41츠0.14, 0.44 르0.12, 0.10±0.10을 보여 AC와 NSD에서 유의성 있게 발생개수를 줄였다.

It is, therefore, essential to have an appropriate animal model for detailed analysis of the role of H. pylori played in gastric carcinogenesis. There is a wealth of evidence to support that over production of inducible nitric oxide synthase(iNOS) and cyclooxygenase-2(COX-2) is involved in the pathogensis of various cancer in both rodents and humans. The aim of this study was to establish a mouse model for H. pylori-associated gastric carcinogenesis and to identify the role of inducible nitric oxide synthase(iNOS) and cyclooxygenase-2(COX-2) played during the gastric carcinogenesis in mice. Eighty-three specific pathogen free, six-week-old male C57BL/6 mice were randomly divided into seven groups. Animals of the group 1, 2, 3, 4 were given MNU in their drinking water at the concentration of 200 p.p.m. for total five cycles of one-week regimen with one-week pause. After completion of MNU administration, they were given autoclaved distilled water for one weeks, and groups 1, 2, 3, 5, 6, 7 were inoculated with H. pylori. After completion of H. pylori. inoculation, groups 2 and 6 were given aminoguanidine in their drinking water at concentration of 1000p.p.m. and animals of group 3 and 7 were given the diet containing 200 ppm nimesulide at 12 weeks of age. All animals were killed at 50 weeks of age. The incidences of the glandular stomach tumors in the group 1, 2, 3 and 4 were 87.5%(14/16), 76.4%(13/17), 44.4(8/18), 10.0%(1/10), respectively and the tumor incidence of group 3(MNU→Hp+nimesulide) was significantly lower than those of group 1(MNU→Hp) at the value of P<0.01. The average numbers of tumors of group 2(MNU→Hp+AG : 1.41±0.24) and group 3(MNU→Hp+nimesulide : 0.44±0.12) were significantly lower than those of group 1(MNU→Hp : 2.62±0.36) at the value of P<0.05. Therefore, overproduced iNOS and COX-2 plays an important role in mice gastric carcinogenesis. We concluded iNOS and COX-2 inhibitor have good effects on gastric carcinogenesis.

남해선,황규윤,,백병준,정윤영,오천환,조성란,박준수 순천향의학연구소;Soonchunhyang Medical Research Institute 2000 Journal of Soonchunhyang Medical Science Vol.6 No.1

To evaluate usefulness of application of MAST-CLA to indetify allergens, authors conducted MAST-CLA allergen-specific IgE assay and collected allergy related symptoms in 118 allergic patients diagnosed at Soonchunhyang University Chunan Hospital during October 1998 through January 2000. The results were as followings; 1. The mean (SD) age was 23.1 (±12.17) years old and teenagers accounted for 33.1% of patients. 2. The frequent allergic symptoms were sneezing (59.3%), rhinorrhea (53.4%), nasal stiffness (44.1%), itching sensation (24.6%), cough or sputum (16.1%), and eye symptom (8.5%) in order. 3. Among these subjects, 62.7% of patients revealed at least more than one specific allergen and 70.3% showed elevated total IgE levels by MAST-CLA. The three most frequent specific allergens were Dermatophagoides farinae (47.5%), Dermatophagoides pteronyssinus (45.8%), and house dust (30.5%). 4. While age was not significantly related to positive of both specific allergens and total IgE (P>0.05), sneezing and nasal stiffness were significantly associated with positive of specific allergen and total IgE, respectively (both P<0.05). 5. Total IgE increased with the number of specific allergens, but both specific allergen and total IgE were not significantly related to increases of allergic symptoms (P>0.05). In conclusion, our data suggest that MAST-CLA allergen-specific IgE assay is useful measure for identification of causative allergens in allergic patients, however, it is recommended that more specific allergic antigens should be determined and replaced or added to Korean inhalent panel of MAST-CLA.
