This study was conducted to develop effective production system in greenhouse for leaves and stems of Angelica acutiloba by using connect pots in 2003 and 2004. Seed germination rate and plant biomass of Angelica acutiloba collected in 2004 were higher than those harvested in 2003. Germination rate of Angelica acutiloba seeds collected in 2003 was 10%, while germination rate of seeds collected in 2004 was above 90%. Especially, plant growth and yield of Angelica acutiloba grown in connect pots sized with 4×4×5cm(length×width×height) were the highest. These results indicate that leaf and stem production of Angelica acutiloba can be improved by using connect pots and optimizing seed collecting time in greenhouse.

An algorithm to automatically extract coordinate and time information from optical observation data of geostationary orbit satellites (GEO satellites) or geosynchronous orbit satellites (GOS satellites) is developed. The optical wide-field patrol system is capable of automatic observation using a pre-arranged schedule. Therefore, if this type of automatic analysis algorithm is available, daily unmanned monitoring of GEO satellites can be possible. For data acquisition for development, the COMS1 satellite was observed with 1-s exposure time and 1-m interval. The images were grouped and processed in terms of “action”, and each action was composed of six or nine successive images. First, a reference image with the best quality in one action was selected. Next, the rest of the images in the action were geometrically transformed to fit in the horizontal coordinate system (expressed in azimuthal angle and elevation) of the reference image. Then, these images were median-combined to retain only the possible non-moving GEO candidates. By reverting the coordinate transformation of the positions of these GEO satellite candidates, the final coordinates could be calculated.

The object of this research is about how jeon-ju, which is one of the historical cities is changed according to the flow of generation. In this analysis, product and enemy factors will be studied. The inner and urban landscape of the generations of the 1860s, 1930s and modern times will be surveyed and compared in the context to grasp those factors. Analysis will be applied to this modern historical city by theorizing how these factors will effect future development. Today's modern landscape will be compared and analyzed based on the effects and abstractions of the recent landscape immediately preceeding current times. Modern conditions will again be placed in context, by suggesting future potential developments. In the result, first, considering present conditions of the landscape which set the stage for the Japanese invasion, an evaluation will be made on the best course of action for future development of street landscape. Second, the question of preserving the history and culture of this rich and ancient city through network of modern street landscape naturally will be posed. Finally, an analysis of the difference between the old and modern landscape will be evaluated, in preparation for suggestions of future development.

Background: Cholestatic hepatitis is failure of bile to reach the duodenum with hepatocellular damage and no demonstrable obstruction of the major bile ducts. The prognosis is usually good with recovery in less than 4 weeks after withdrawal of the offending drug. However, a prolonged course lasting over 3 months is possible and, in rare cases, progression to ductopenia with development of a vanishing bile duct syndrome occurs. A differential diagnosis with other causes of Chronic liver disease is needed. Materials and Methods: From January 1991 through Jaunary 2000, 14 patients diagnosed as cholestatic hepatitis by liver biopsy were inclouded. The possible causative drug, clinical features, laboatory findings, and progression of cholestatic hepatitis were evaluated. The semiquantitative study of liver lesions was performed by two independent observers. Results: Causes of cholestatic hepatitis are 5 cases of oriental medicine, 3 cases of anti-tuberculosis medication, 1 case of ticlopidine and antibiotics and 4 cases of unknown causes. The clinical features of cholestatic hepatitis were jaundice, itching, urine color change, and general weakness. During 6 to 30 months, LFT of 5 patients showed prolonged elevation. Elevated total cholesterol ≥250 mg/dL in 6 patients, pheripheral blood eosinophilia in 5 patients, auto-antibody positive in 6 patients were observed respectively. The biopsies showed intralobular bilirubinostasis with a mixed portal inflammatory infiltration. Conclusion: In cholestatic hepatitis. durations of abnormal LFT are variable regardless of causative drugs. If cholestatic hepatitis progresses toward chronic course, viral hepatitis, primary biliary cirrhosis, and autoimmune hepatitis should be differentially diagnosed and sequential liver biopsies are needed.

Isoquinolinium dichromate[(C_(9)H_(7)NH)₂Cr₂O_(7)] was synthesized by the reaction of isoquinoline with chromium(VI) trioxide in water. isoquinolinium dichromate[(C_(9)H_(7)NH)₂Cr₂O_(7)] structure was verified by IR. EA and ICP. The oxidation of benzyl alcohol by isoquinolinium dichromate[(C_(9)H_(7)NH)₂Cr₂O_(7)] in carious solvents showed that the reactivity increased with the increase of the dielectric constant s order: cyclohexen < chloroform < acetone < acetonitrile. In the presence of acid, isoquinolinium dichromate [(C_(9)H_(7)NH)₂Cr₂O_(7)] oxidized the substituted benzyl alcohols in N,N-dimethylformamide. The Hammett reaction constant p was -0.69 at 303K. The observed experimental data was used to rationalize the hydride ion transfer in the rate-determining step.

Objective: To study on the incidence of complications from C-arm guided lumbar transforarninal epidural injections in patients with radiculopathy caused by either lumbar spinal stenosis or herniated intervertebral disc. Materials & Methods: A total of 1200 patients with back/leg pain for more 3 months and received therapeutic injections in recent 1-year period was evaluated. All procedures were performed by one neurosurgeon with careful monitoring by nursing staffs during and after the procedures. Two party observers reviewed medical charts including immediate postprocedure complications using standardized questionnaire. Results: Average 1.9 injections per patient were done. Complications per injection seen included 12 transient headaches (0.9%), 5 increased back pain(0.4%), 4 increased leg pain(0.3%), 4 facial flushing(0.3%), 2 increased blood sugar in an insulin-dependent diabetic(0.2%), I vasovagal reaction(0.08%), and I hypertension(0.08%). All of these complications resolved within several hours to 2 weeks and there were no need for further specific management. There were no major or permanent complications. The incidence of minor complications was 2.3% per injection. All reactions resolved without morbidity. Conclusion: Although effectiveness varies with different pathologies, the C-arm guided lumbar transforaminal epidural injection seems to be a safe and effective procedure for these patients when carefully performed and closely observed with appropriate nursing care.

This study was performed to evaluate the temperature rise on various position of the Buchanan plugger, the peak temperature of plugger's type and the temperature change by its touching time of heat control spring. The heat carrier system 'System B' (Model 1005. Analytic Technologies, USA) and the Buchanan's pluggers of F, FM, M and ML sizes are used for this study. The temperature was set to 200℃ which Dr. Buchanan's "continuous wave of condensation" technique recommended on digital display and the power level on it was set to 10. In order to apply heat on the Buchanan's pluggers, the heat control spring was touched for 1, 2, 3, 4 and 5 seconds respectively. The temperature rise on the surface of the pluggers were measured at 0.5 mm intervals from tip to 20 mm length of shank using the infraed thermography (Radiation Thermometer-IR temper, NEC San-ei Instruments, Ltd, Japan) and TH31-702 Data capture software program (NEC San-ei Instruments, Ltd, Japan). Data were analyzed using a one way ANOVA followed by Duncan's multiple range test and linear regression test. The results as follows. 1. The position at which temperature peaked was approximately at 0.5 mm to 1.5 mm far from the tip of Buchanan's pluggers (p<0.001). The temperature was constantly decreased toward the shank from the tip of it(p<0.001). 2. When the pluggers were heated over 5 seconds, the peak temperature by time of measurement revealed from 253.3±10.5℃ to 192.1±3.3℃ in a touch for 1 sec, from 218.6±5.0℃ to 179.5±4.2℃ in a touch for 2 sec, from 197.5±3.0℃ to 167.6±3.7℃ in a touch for 3 sec, from 183.7±2.5℃ to 159.8±3.6℃ in a touch for 4 sec and from 164.9±2.0℃ to 158.4±1.8℃ in a touch for 5 sec. A touch for 1 sec showed the highest peak temperature, followed by, in descending order, 2 sec, 3 sec, 4 sec. A touch for 5 sec showed the lowest peak temperature (p<0.001). 3. A each type of pluggers showed different peak temperatures. The peak temperature was the highest in F type and followed by, in descending order, M type, ML type. FM type revealed the lowest peak temerature (p<0.001). The results of this study indicated that pluggers are designed to concentrate heat at around its tip, its actual temperature dose not correlate well with the temperature which Buchanan's "continuous wave of condensation" technique recommended, and finally a quick touch of heat control spring for 1 sec reveals the highest temperature rise.

Natural compounds such as free sugars, minerals and composition amino acids in Darae(Actinidia arguta) and Korean stewartia(Stewartia koreana) saps were analyzed to establish to the basic data of foods. Free sugars of the saps determined were fructose and glucose which were detected higher amounts as 378.4 and 125.4㎎/100㎖, respectively, but sucrose and maltose were not detected. Among 10 kinds of mineral detected in the saps, the content of calcium in Darae and aluminum in the Korean stewartia saps was the highest 172.0 and 56.1㎎/ℓ, respectively. The calcium content in Darae saps was 13 times higher than that of Korean stewartia saps. The Darae saps were composed of 4 kinds of amino acids such as cystine, aspartic acid, serine and valine, and then Korean stewartia saps 6 kinds of amino acids such as cystine, glutamic acid, aspartic acid, serine, valine and phenylalanine. It is concluded that saps of Darae and Korean stewartia contain a good variety of natural compounds such as free sugars, minerals and amino acids to serve as an excellent source of very natural and health promoting drinks.
