A pilot scale SBR (working volume, 20㎥) treating piggery wastewater was operated with real wastewater. The operation mode of intermittent feeding of raw water and sub-cycle with repeating anoxic-aeration conditions were adapted to avoid the high-strength nitrogen inhibition. In sub-cycle, aeration time for nitrification was tried to be controled with ORP and/or DO meter. The characteristics of control was somewhat different between ORP and DO. DO showed potential ability to detect complete ammonia oxidation point by the first order differential values or absolute value. Especially, DO was proved to be useful for high loading rates. ORP indicated the ending point of nitrification by the plateau appearing after bending point. Because ORP can be utilized as a diagnosis tool by its good sensitivity for the microbial condition in reactor, the simultaneous application of DO and ORP was recommended for the stable control of SBR.

Seasonal parasitism of adult Riptortus clavatus (Thunberg) (Heteroptera: Alydidae) by the tachinid fly parasitoid, Dionaea magnifrons (Herting), was monitored at three sites in Korea, 2006 by using the aggregation pheromone traps of R. clavatus. Basic developmental characteristics of the parasitoid were also examined. Annual parasitism of R. clavatus female and male adults was 6.8 and 11.6%, respectively. Parasitism of females and males of the over-wintering (Oct. to Jun.) generation (10.6 and 16.5%, respectively) was higher than the summer (Jul. to Sep.) generation (2.1 and 2.5%). Maximum parasitism for males was recorded during spring or autumn, reaching 35.6, 25.0, and 26.9% at the university campus, and pear and sweet persimmon orchards, respectively. Sex ratio of all the D. magnifrons was slightly male-dominated (62.2%). The pupal period of D. magnifrons was 9.2 days for both sexes in room temperature conditions. D. magnifrons larvae escaped from R. clavatus in 8.0±3.4 days after host bug collection fromthe field during April to September, whereas in October and November they emerged in 15.1±3.8 days. This parasitoid fly should be studied further to determine its effectiveness as a biological control agent complementary to existing strategies in the management of bean bug.

Study objective: To recognize importance of pain management in ED and properly manage the ED patients complaining pain by analyzing the intervals between arrival time in ED and pain medicine starting time, the types and the administered routes of pain medicine. Design: Retrospective review of ED charts Setting: University teaching hospital Participants: The patients had admitted in ED of Yeungnam University Hospital with a chief complaint of acute abdominal pain or pain due to bone fracture between June 1, 1995 and December 31, 1995. Results: The study group consisted 256 patients, 161 of them female. ED administrations of analgesics were 103 cases, 17 of them administered more than two times. The average time interval between arrival time and medication time was 169.02±120.25 minutes. Each types of perceived analgesics were antispasmodics 55 cases(53.40%), NSAID 26 cases(25.24%) and opioid 19 cases(18.45%). Every analgesics were administered through intramuscular routes, except only 3 cases. Violences of patients or relatives due to delayed pain control were occured 32 cases, 5 cases of them self-discharged and looked for other hospitals. Conclusion: Emergency physicians including interns and residents delayed management so long and ordered inappropriate administration routes and types of analgesics. So we thought proper protocols about pain management in ED were established.

Background and Objectives : The cell-cell adhesion molecule E-cadherin is necessary for the maintenance of the epithelial cellular structure. We were designed to confirm the significance of E-cadherin as a marker for differentiation and invasiveness of squamous cell carcinoma of the larynx and hypopharynx. Materials and Methods : Our study was investigated for the immunohistochemical expression of the epithelium-specific cell adhesion molecule E-cadherin in formalin fixed paraffin embedded tissue specimen of 32 cases of squamous cell carcinoma of larynx and hypopharynx. Results : The positive expression of E-cadherin was 56.3%(18 cases) in squamous cell carcinoma of the larynx and hypopharynx. Decreased E-cadherin expression was a stastistically significant correlation with a increased grade of lymph node stage and clinical stage. Reduced expression was seen in the large tumor size and poorly differentiated tumors, but these result was not statistically significant. Conclusion : The expression of E-cadherin may be related with progression of squamous cell carcinoma of the larynx and hypopharynx. But these correlation were not sufficient for the prognostic indicators in squamous cell carcinomas of the larynx and hypopharynx.

We have isolated a carbohydrase(dextranase and amylase; DXAMase) hyper-producing constitutive mutant from Lipomyces starkeyi JLC26 using ultrasoft X-ray irradiation obtained from Pohang accelerator laboratory(PAL). After partial purification of dextranase and amylase by membrane filtration, PEG, and DEAE-Sepharose column chromatography, the specific activities of amylase and dextranase were 3193 and 2822 unit/mg, respectively. The pH effects for activity and stability of both enzymes were similar to each other: Optimum pH and temperature for activity were at 5.5 and 50℃ and optimum ranges for stability were at pH 2.5-6.0 and 4-37℃, respectively. When the enzyme and maltotriose were reacted, glucose, maltose, isomaltose, maltotriose, panose and α (1→6) glucosylmaltotriose were produced by disproportionation reaction. When the enzyme and nigerose were reacted, glucose, nigerose, new product were produced.

1. Dasan exert his effort to offer the opportunity of the Government Service Examination for all the people evenly without restriction of classes, pedigrees, regions, and parties, though it is restricted within identical social stratum. Such as to assign the qourum of examinee regionaly, to cease the special examination system centered capital city and establish the Three Years Grand Examination System, to improve the procedures of examination equitably and strengthen the royal-exam step or royal court-exam step, to examine comprehensive capacity of examinee through manifold subjects are a link in a chain of efforts. 2. Dasan formulates a plan to equalize qualification of applicants, steps and procedures of examination, number of applicants, appointment of successfull examinee institutionally and practically between the military and the literary examination system. Dasan's idea like this is to realize the ideals of equality between two systems. 3. Dasan suggests 8 steps examination system insntead of traditional system. The traditional system has five steps, the first two step is preliminary examination, the second two step is main examination, and the last step is ranking examination. But Dasan system has 8 steps ; 1) town-selection(選擧) 2) state-exam(州試) 3) provincial -exam(省試), 4) assemble-exam(會試), 5) capital - exam(都試), 6) capital - assemble - exam(都會), 7) royal - exam(殿試) and 8) royal - court - exam(朝考). The system aims to ensure validity, reliability, objectivity, and also to strengthen sovereign power of royalty. 4. Dasan asserts the Three Years Grand Examination System(式年大比) as regular intervals. Because special irregular examination incurred so many abuse as lowering of officers standards, corruption and deprevation of examiner and examinee, disorder of examination place and waste of expenses. 5. Dasan suggests the town system. The system was that applicant has to be recommended by elders of towns and villages before the state-examination. It results various effects, such as to make examinees behave sincerely in ordinary days, and to prevent abuse of the examination. 6. Dasan suggests quorum of examinees by step and region to reduce the abuse caused by unlimited application, to balance demand and supply between number of successful examinees and officer's positions, and to prevent concentration of opportunities to capital city area. 7. Dasan suggests that applicants have to be examined virtuous conduct firstly with academic abilities and literary arts in order to evaluate harmonized whole-person. Dasan also emphasizes national history among examination subjects. It means his sovereignty and independency to try to surmount the worship of powerful China. 8. To heighten and validity of evaluation, Dasan suggests to grade examination papers jointly and openly. 9. Strengthening the function of the royal-exam step and the royal-court-exam step means to raise the sovereign power of royalty consequently, through the reconfirmation of evaluation results conducted by bureaucrat. On the one hand, the Literary Government Examination System of Dasan has critical points also as followings : 1. that it is little removed from the system which is to select officials for dynasty structure. 2. that the 8 steps examination system is complicate exceedingly in practice. 3. That the subjects of examination are not stipulated in the degree of difficulty in spite of the same subjects are made questions repeatedly. 4. that the applicant is determined by social position not by his ability.
