토마토 ‘모모타로’를 공시하여 셀레늄 10㎎ㆍL?¹의 관주 및 엽면시비 등의 단용 및 혼용처리가 수경재배 토마토의 생육 및 과실 내 셀레늄 축적 함량에 미치는 영향을 구명하였다. 토마토 종자를 50공 트레이에 파종하여 70일 동안 육묘한 후 유묘를 코코피트 슬라이브를 이용한 수경재배 시스템에 정식하였다. 양액은 일본원예시험장 배양액 표준처방으로 조성하였으며, pH 5.8~6.2와 EC 2.3 ㎎ㆍL?¹ 등으로 조절하여 공급하였다. 셀레늄은 무기태 SeO₂와 sugar fatty acid ester에 킬레이트화 한 유기태 셀레늄을 10 ㎎ㆍL?¹으로 조성하여 관주, 엽면시비, 관주와 엽면시비를 병행하여 처리하였다. 초장, 엽수, 엽면적 및 엽록소 등의 토마토 생장반응은 셀레늄의 엽면시비, 그리고 엽면시비와 관주를 병행한 처리구에서 현저히 증가하였다. 과실 내 셀레늄 축적 함량은 킬레이트화 한 유기태 셀레늄을 엽면시비와 관주를 병행하여 처리한 경우에 0.302 ㎎ㆍL?¹으로 가장 높았다. 무기태와 유기태 셀레늄의 엽면시비와 관주 등의 단용 처리 보다는 혼용 처리가 전반적인 과실 생장과 체내 셀레늄 축적에 효과적이었다. 무기태 설레늄(SeO₂) 보다는 sugar fatty acid ester에 킬레이트화한 유기태 셀레늄 처리가 셀레늄을 함유한 기능성 토마토의 수경재배에 더 효과적이었다. This study was conducted to clarify the effects of supplying methods of selenium on the growth and Se uptake of hydroponically grown tomato plants. Tomato seeds (Lycopersicum esculentum Mill. cv. Momotaro T-93, Daki Seed Co.) were sown in plug tray with fifty holes, and raised for sixty days. Tomato seedlings transplanted to coco fiber slabs were supplied with the nutrient solutions adjusted to EC 2.3 dSㆍm?¹ and pH 5.8~6.2 recommended by the Japanese Horticultural Experiment Station. Selenium forms used were inorganic SeO₂ (here in after referred to Se) and organic selenium chelated with sugar fatty acid ester (here in after referred to chelated-Se). 10 ppm selenium solutions were treated to tomato plants with foliar applications, drenching, and foliar application plus drenching. Growth characteristics in terms of plant height, number of leaves, leaf area and chlorophyll content were significantly increased in the plot of foliar application of Se, and in the plot of foliar application plus drenching of chelated-Se than other plots, respectively. Transported contents of selenium into the tomato fruits were highest as 0.302 ppm in the plot of foliar application plus drenching of chelated-Se. Also, it had tended to be higher in the plot of foliar application plus drenching than in the plots of foliar application or drenching in both of Se and chelated-Se. Foliar application and drenching of organic chelated-Se were effective to produce the functional tomato fruits.

Objectives: To study the clinical manifestations; time, mode of delivery, size of myomas and outcome of pregnancy in cases of myomas that were detected prior to pregnancy or during the antenatal care and after delivery. Methods: We statistically analyzed 76 patients with uterine myomas in pregnancy admitted to Soonchunhyang Seoul Hospital during the period of Jan. 1999 and Dec. 2001. Results: The results are as follows. 1. The mean age of patients in the detected group and undetected group were 32.9 years and 32.3 years, respectively. There was no difference in the proportion of primarity between the detected group(98.2%) and the undetected group(79.6%) 2. The most common type of uterine myoma in both groups was intramural myoma (detected group 94.1% vs undetected group 81.3%). The uterine myomas were most commonly located in the anterior portion and fundus(detected group 52.9% and 23.5% respectively vs undetected group 47.4% and 23.7% respectively) and the proportion was not significantly different between the two groups. Uterine myomas with a diameter of 3cm or more in the detected group were detected by clinical examination and ultrasonogram. Rate of uterine myomas with a diameter of 3cm or more in the detected group is 76.5% and less than 3cm is 54.2% which detected incidentally at delivery. 3. The proportion of term infants were detected group 88.2% vs undetected group 91.5%. 4. The most common indications for cesarean section in both groups were cephalopelvic disproportion and repeated cesarean section (detected group 41.2% and 45.8% respectively vs undetected group 11.8% and 18.6% respectively) and there was no significant difference between the two groups. 5. Secondary pathologic changes in the all myomectomy specimens were degeneration in both groups but there was no necrosis or sarcomatous change. 6. Antenatal complications were preterm labor, premature repture of membranes, spontaneous abortion, malpresentation, and placenta previa. Intrauterine growth retardation and placental abruption were not seen in both groups. Conclusion: Myoma detected by ultrasonogram before or during pregnancy is not a significant implication of pregnancy outcome.

The purpose of this study is compare the effects of two therapeutic processes-ⅰ) conservative Myofacial Release Technique along and ⅱ) Transcutaneous Electrical Nerve stimuliation alone - on the increase in the range of motion(ROM) and on the decrease in patient's pain with chronic Neck pain. The subjects of the study were student with choronic neck pain in Daegu health university. Half of them (10) took conservative Myofacial Release Technique along and the others (10) took Transcutaneous Electrical Nerve stimuliation alone.I used 3D Motion analysis. The range of motion (ROM) in six areas-flexion, extension, left lateral flexion, right lateral flexion, left rotation, right rotation-to check the effectiveness of the two combinations of methods, measured pain with visual analogue scale (VAS) to see the effect on pain reduce. Assement was conducted to the groups before the treatment began and affer the four weeks treatment ended. This study shows that both groups demonstrated significant improvement in ROM increase and pain reduction. Flexion ROM increases were significant in MFR and TENS after treatment 2 weeks and 4 weeks. Extension ROM increases were significant in MFR and TENS after treatment 2 weeks. Right rotation ROM was no significant differences were found in MFR and TENS after treatment all weeks. Right lateral flexion ROM increases were significant in MFR and TENS after treatment 3 weeks. Left lateral flexion ROM increases were significant in MFR and TENS after treatment 1 weeks. But the others no significant differences were in MFR group and TENS group during 4 weeks.

본 연구에서는 3차원 정육면체 가열로 내의 전도-대류-복사 복합열전달 특서을 해석하였으며, 연소가스의 유입속도, 벽면의 반사율과 매체의 흡수계수 등과 같은 인자들의 변화에 따른 영향을 살펴보았다. 가열로의 벽면들은 단열되어 있고 가열로 내부로 일정한 온도의 연소가스가 유입될 때 시스템 내부의 온도는 유입 온도와 비슷하게 균일한 온도 분포를 갖는 것으로 예측할 수 있었다. 유입 속도가 증가하더라도 가열로 내부의 온도에는 거의 영향을 미치지 않았으며, 가열로는 유입되는 연소가스의 흡수계수가 증가할수록 가열로 내부의 온도는 보다 균일하게 된다. 또한, 가열로 내부 벽의 반사율이 커질수록 벽의 온도는 감소하고 또한 벽면에 작용하는 유효복사열유속은 증가함을 알 수 있었다. 이러한 해석 결과로부터 가열로 내부의 온도 분포는 매체의 흡수계수가 클수록 그리고, 벽면 반사율이 작을수록 일정하게 유지될 수 있다는 것을 알 수 있었다. 그리고 이러한 결과들을 종합하여 볼 때 가열로의 설계 시 일정한 열의 유입과 가열로를 단열시키는 것이 중요하며, 그리고 매체의 흡수 계수를 크게 하고, 그리고 벽면의 반사율을 작게 하는 것은 가열로 내부의 온도를 일정하게 유지할 수 있는 중요한 조건이 된다는 것을 알 수가 있었다.

The stabilization of fuel-rich/lean laminar premixed flames has been studied experimentally using a slot burner. Fuel-rich flames hold the fuel-lean flame and suppress the flame blow-out phenomena. At the presence of fuel-rich flames, the tip of the fuel-lean flame remains closed even at equivalence ratios below the lean flammability limit. It was demonstrated that fuel-rich flames could stabilize the fuel-lean flame for the equivalence ratio as low as 0.2. The increase of heat release rate of the fuel-rich flame lowers the equivalence ratio limit of the stable fuel-lean flames. The stability of fuel-lean flames, however, is not sensitive to the equivalence ratio of fuel-rich flame. The mechanism that is responsible for the flame stabilization appears to be similar to that of a triple flame.

Estimation of landfill leachate generation is main issue that determain leachate collection system and scale of disposal system. Other reason is indirect estimation of damage of collection, drainage and disposal system for generation difference and control. The subject of this study is that Sudogwon landfill site #1 is landfill closure site. Actual leachate start 493 m^(3)/day at Jan. 1993 and maintain 5,000∼7,000 m^(3)/day after 1997. The other side estimation from HELP Model is 3,000∼6,000 m^(3)/day for same period. But concerned with condensation water and compression by increased layers, historical actual leachate geneation and estimation from HELP Model are similar.

Adult polycystic kidney disease(APKD) usually accompanies with renal and extrarenal manifestations and liver cysts are present in aproximately 30% of patients with APKD. Kidney cysts often accompany with hemorrhage, rupture, infection, however, liver cysts are usually asymptomatic and do not impair liver function. Rare complication of liver cysts in patient with APKD include portal hypertension with bleeding esophageal varices and hepatic failure with encephalopathy. But, in APKD patient, infection of liver cysts without infection of renal cysts is extremely rare. We report a case of infected liver cyst in a patient with APKD who has complained generalized abdominal pain and high fever which was confirmed by ultrasound and aspiration. The patient was treated successfully with repeated aspiration and systemic antibiotics.

The water level and flow rate data measured at Indogyo measurement point which serves as one of the major measuring points of Han River have been very important in aspect of controlling the flow. Because these data are becoming more and more unreliable due to the recent change in the basin or the narrowing of the river width, these data will be standardized by comparing the recent data of Indogyo measuring point with the past those. To minimize the errors of water level-flow rate curve caused by the yearly changes of basin, the standard water level-flow rate curve with respect to the present basin conditions will be set, and calculated reduced water level will be compared with the past data. And through frequency analysis, frequency-based flood level with respect to return period will be presented. Finally, the total flow rate of the flood measured in September, 1990 at the point of Indogyo measuring point will be compared with the total flow of the past extreme floods.
