To make a objective diagnosis of the syndrome of cold-limbs, We investigated the 20 patients with cold limbs and GI trouble and 20 normal people as a control group. And we compared the thermal difference between Chon-jung(CV17) and Chung-wan(CV12 中脘), Chon-jung(CV17) and Ki-hae(氣海 CV6) and we compared the thermal differences of No-gung(PE8 勞宮) and Yong-chon(湧泉 KI1), too. The results were as follows. 1. All 20 patients had GI trouble and cold limbs. They had the symptom-Indigestion(16 cases-80%) with heart burn, tympanites, abdominal distention, hiccup, belching. Beside that symptom they also had constipation(6 cases-30%), diarrhea(3 cases-15%), headache & dizziness(6 cases-30%). And some had the menstrual syndrome, chronic fatigue, palpitation, insomnia, edema, arthralgia. 2. The thermal difference of the palms between the patients group and the control group were $25.70^{\circ}C,\;25.82^{\circ}C$, but they were not significant. 3. The thermal difference of the soles between the patients group and the control group were $23.58^{\circ}C,\;24.42^{\circ}C$ and the significancy was P=0.020 so it was significant(P<0.05). 4. The thermal difference of the palms and Chon-jung(CV17) between the patients group and the control group were $1.08^{\circ}C,\;0.76^{\circ}C$, but they were not significant. 5. The thermal difference of the sales and Chon-jung(CV17) between the patients group and the control group were $3.01^{\circ}C,\;1.90^{\circ}C$ and the significancy was P=0.003 so it was significant(P<0.05). 6. The thermal difference of Chon-jung(CV17) and Chung-wan(CV12 中脘) between the patients group and the control group was $0.30^{\circ}C,\;0.62^{\circ}C$ and the significancy was P=0.793 so it was significant(P<0.05). 7. The thermal difference of Chon-jung(CV17) and Ki-hae(CV6 氣海) between the patients group and the control group was $0.53^{\circ}C,\;0.68^{\circ}C$, but they were not significant. From the above, I could find the significance of D.I.T.I to diagnose the cold-feet not the cold-hands and the thermal difference between the trunk and limbs was more significant on cold-feet than on cold-hand, either.

The purpose of this study was to compare the fracture resistance of the IPS Empress ceramic crown with 1.0mm width rounded shoulder, which is usually recommended in all ceramic crown, and 0.5mm width chamfer finish lines on the maxillary central incisor. After 15 metal dies were made for each group, the IPS Empress all ceramic crowns were fabricated and cemented with resin cement(Bistite resin cement, Tokuyama Soda Co. LTD., Japan) on the metal die. The cemented crowns were mounted on the positioning jig and the universal testing machine(Zwick Z020, Zwick Co, Germany)was used to measure the fracture strength, with loading on the incisal edge. And also, three-dimensional finite element stress analysis was used to measure the stress distribution with the various types of the finish lines (1.0mm width rounded shoulder, 0.5mm width chamfer), the loading site (incisal edge, incisal ⅓), and the type of loading(concentration loading, distribution loading). The results of this study were as follows. 1. In the fracture resistance experiment according to the finish line, the mean fracture strength of rounded shoulder(876N) and the mean fracture strength of chamfer(882N) did not show any significant difference between each other(p>0.05). 2. The stress distribution of all ceramic crown in three dimensional finite element analysis showed concentration aspect at loading point and cervical area of labial surface. 3. In metal die, there were no differences in stress distribution between finish lines, but in natural teeth model, chamfer finish line showed higher stress than rounded shoulder finish line. 4. When force was loaded on the incisal edge, the stress was concentrated on the incisal edge and the cervical area of labial surface. When force was loaded on the incisal ⅓, the stress concentrated on the cervical area of labial surface and the cingulum area. 5. Generally, natural teeth model showed higher and various stress than the metal die.

목적: 생존심근 진단에 있어 니트로글리세린 투여 Tc-99m-MIBI 게이트 심근SPECT의 진단성능을 휴식/지연재분포 Tl-201 심근SPECT와 비교하였다. 대상 및 방법: 22명의 관상동맥질환에서 Tl-201휴식/디피리다몰 부하 Tc-99m-MIBi 게이트/ 지연재분포 Tl-201 심근SPECT를 시행하였다. 이 때 게이트SPECT 시행 후 니트로글리세린 0.6mg을 설하 투여하고 연이어 그 자리에서 게이트 SPECT를 1회 더 반복 시행하였다. 환자들에서 관상동맥우회로술을 시행하고 3개월 후 게이트 심근SPECT를 추적검사로 시행하였다. 20 분절 모델을 이용하여 각 분절에서 휴식, 지연재분포, 기저상태와 니트로글리세린 투여 후의 심벽운동 및 수축기비후화 등을 정량하였다. 정량화된 생존심근 예측지표들 중, (1) 휴식기 Tl-201 섭취, (2) Tl-201 지연재분포, (3) 기저상태의 수축기비후화, (4) 니트로글리세린 투여 후의 수축기비후화, 네 가지의 예측성능을 평가하고 비교하였다. 결과: 총 100개의 분절이 분석에 포함되었으며, 이 중 66개(66%)의 분절이 재관류 후 기능 회복을 보였다. 최적 기준점인 50%를 기준으로 하였을 때, ROC 곡선 분석에서 휴식기 Tl-201 섭취와 Tl-201 지연재분포의 민감도, 특이도는 각각 79%와 44%, 그리고 82%와 44%였다. 또한 15%를 기준으로 하여, 기저상태 수축기비후화와 니트로글리세린 투여후 수축기비후화의 민감도, 특이도는, 각각 49%, 50%와 64%, 65%였다. ROC 곡선의 AUC는 니트로글리세린 투여 후 수축기비후화가 기저시 수축기비후화에 비하여 유의하게 높았다(p=0.004). 결론: 니트로글리세린 투여 Tc-99m-MIBI 정량적 게이트 심근SPECT는 기능이상 심근에서 기능 회복을 예측하는데 유용한 검사이다. The performance of nitroglycerin-challenged Tc-99m-MIBI quantitative gated SPECT for the detection of viable myocardium was compared with rest/ 24-hour redistribution TI-201 SPECT. Materials and Methods: In 22 patients with coronary artery disease, rest Tl-201/ dipyridamole stress Tc-99m-MIBI gated/ 24-hour redistribution TI-201 SPECT were performed, and gated SPECT was repeated on-site after sublingual administration of nitroglycerin (0.6 mg). Follow-up gated SPECT was done 3 months after coronary artery bypass graft surgery. For 20 segments per patient, perfusion at rest and 24-hour redistribution, and wall motion and thickening at baseline and nitroglycerin-challenged state were quantified. Quantitative viability markers were evaluated and compared;(1) rest thallium uptake, (2) thallium uptake on 24-hour redistribution SPECT, (3) systolic wall thickening at baseline, and (4) systolic wall thickening with nitroglycerin-challenge. Results: Among 100 revascularized dysfunctional segments, wall motion improved in 66 segments (66%) on follow-up gated myocardial SPECT after bypass surgery. On receiver operating characteristic (ROC) curve analysis, the sensitivity and specificity of rest and 24-hour delayed redistribution TI-201 SPECT were 79%, 44% and 82%, 44%, respectively, at the optimal cutoff value of 50% of Tl-201 uptake. The sensitivity and specificity of systolic wall thickening at baseline and nitroglycerin-challenge were 49%, 50% and 64%, 65% at the optimal cutoff value of 15% of systolic wall thickening. Area under the ROC curve of nitroglycerin-challenged systolic wall thickening was significantly larger than that of baseline systolic wall thickening (p=0.004). Conclusion: Nitroglycerin-challenged quantitative gated Tc-99m-MIBI SPECT was a useful method for predicting functional recovery of dysfunctional myocardium.

Upper gastrointestinal bleeding is common and potentially life threatening medical emergency. Emergency endoscopy is the first choice of diagnostic and treatment measure for patients with active upper gastrointestinal bleeding. Histoacryl should be considered a second-line treatment modality when conventional treatments were failed. However, it might cause several complications. Herein, we report a case of acute pancreatitis developed after histoacryl injection therapy for active duodenal ulcer bleeding. A 71-year-old man was admitted with melena and hematemesis. On emergency endoscopy, a 2 cm sized active ulcer with bleeding from an exposedvessel was seen at the duodenal bulb. Attempts to arrest the bleeding with hemoclipping and submucosal epinephrine injection were tried, but failed. We changed the method to endoscopic histoacryl injection, and obtained hemostasis immediately. A few hourslater, after successful hemostasis, patient complained diffuse abdominal pain. Ultrasonography revealed hyperechoic heterogenous diffuse pancreatic enlargement and right pararenal space fluid collection, this ultrasonographic findings and elevated serum pancreatic enzymes are compatible with acute pancreatitis.

ABSTRACT This study was accomplished to look into the response of main growth characters, yield and chemical composition of Cheju local cowpea on Cheju Island based on the difference between seeding rate. The study took place between May and September, 1998. Number, of days to flowering tended to be delayed as the seeding rate increased. Plant length was the longest at 6kg/10a treatment and the next one was at 5kg/10a treatment. The shortest came from 2kg/10a treatment, 275 cm, 271 and 220cm respectively. Number of branchs and stem diameter became weaker as the seeding rate increased. Fresh forage yields per lOa was the heaviest which weighed 6,073kg at 6kg/10a treatment and 5,840kg at 5kg/10a treatment respectively. The rest decreased gradually. Dry matter yields per lOa, crude protein yields per lOa and total digestible nutrient yields per lOa showed a similar tendency to fresh yields per lOa. The percentage of crude protein and crude fat got higher as the seeding rate increased, but the percentage of crude ash and crude fiber rather tended to decrease. Nitrogen free extract and total digestible nutrient percentages were similar to the change of crude protein percentage. SPAD reading values were the highest at 6kg/10a and 5kg/10a treatment.

It is necessary to provide sufficient daylighting for the high quality lighting in interior space. In these days various kinds of daylighting systems are developed and applied to buildings, however the difference of the purpose of an object room and a physical environment makes the Daylighting system to be unuseful. Therefore it is necessary to estimate the performances of the Daylighting system using the Computer program to apply the Daylighting system usefully. The purpose of this study is to develop the computer program using the Monte Calro Method and Ray-tracing technique to estimate the performances of the Daylighting system in interior space and the consumption of electric energy by dimming control of electric lighting. The accuracy of the computer model was validated through measurements with physical scale models under real clear sky conditions.
