This study was designed to evaluate the disinfection performance in water treatment plants (WTPs, n=16) in Seoul. Disinfection requirement based on the SWTR (Surface Water Treatment Rule) of the U.S. (0.5-log and 1.5-log Giardia removal) was applied in estimating the disinfection performance of WTPs in Seoul. The water treatment process or unit steps used for this evaluation includes inlet pipe line, flocculation basin, sedimentation basin, clearwell, and storage tank. The major results are as follows. First, it was found that all WTPs in Seoul meet a virus removal criteria (4-log removal). Second, the baffling factors (T_10/T) in treatment processes used for this evaluation which was selected by Seoul Water Works were found 1.0 for inlet pipe line, 0.2 for flocculation basin, 0.7 for sedimentation basin, and 0.5 for clearwell, respectively. Since the selection of right baffle factors (T_10/T) is critically important, further rationalization is required in this process. Residual chlorine concentration in clearwell varied from 0.4 to 1.0mg/L. Third, for the disinfection criteria of 3-log Giardia inactivation, almost all of disinfection data which were provided by Seoul Water Works can meet the CT requirement even at worst water quality condition. However, if disinfection criteria is strengthened to 4-log Giardia inactivation, then only 38% of disinfection data can meet the CT requirement. Rational disinfection criteria need to be developed, based on the occurrence of Giardia or other indicating microorganisms occuring in source water. Fourth, significant improvement of disinfection performance in 2001 at all WTPs in Seoul was made as compared to that of 1999 year.

Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.

This study was conducted to investigate the characteristics of disinfection by-products formation potential (DBPFPs) of dissolved organics. Dissolved organics in raw water were separated into two fractions ((1) hydrophilic and (2) hydrophobic) for the measurement of DBPs. Three types of DBPs (trihalomethanes (THMs), haloacetic acids (HAAs), and total organic halides (TOX)) were measured at 3days and 7days incubation time. Sample waters were collected from the Han River and the Wonchun Reservoir. Two major findings are as follows. First, THMFPs/DOC, HAAFPs/DOC and TOXFPs/DOC in the hydrophilic organic component had a level of lower value than those of the hydrophobic organic component. Brominated THMs and bominated HAAs were not found in the chlorinated hydrophobic organic component. Second, the magnitude of HAAFPs/DOC were higher than that of THMFPs/DOC in both hydrophilic and hydrophobic organic components. This results support the reported observation that HAAs formations were higher than that of THMs in chlorinated drinking water. THMFPs and HAAFPs comprised 53-91% of TOXFP.

This study was conducted to investigate the haloacetic acid (HAAs) formation characteristics in raw and treated water in Korea. The raw and treated water from the five major rivers were examined to measure the HAAs concentrations and compared those with literature values. Major findings are as follows. First, average HAAs concentration of treated water (collected from three water treatment plants) in Korea appeared to be 62.5±66.7㎍/L (n=7) and this level is higher than the average trihalomethanes (THMs) concentration (13.2±12.9㎍/L, n=6933) reported recently. Second, the average formation potential of TCAA and DCAA after three days was found as 103±74㎍/L (n=14) and 76±36㎍/L (n=14), respectively. As this result was applied to US-EPA developed model equation for TCAA and DCAA formation, dissolved organic matter (DOM) in Korea has a tendency to produce more TCAA and DCAA as compared to US. This phenomenon was especially notable in DCAA. The sum of weight percentage of TCAA and DCAA which are individual component of HAAS was composed of 80% of HAAs.

Objective : The aim of this study was to review systemically clinical trials on the effectiveness and safety of herbal medicines in the treatment of osteoarthritis. Methods : Computerized literature searches were carried out on seven electronic databases, and hand-searching on some chinese medical journals in library of Kyung Hee Medical Center. Trial data were extracted in a standardized, predefined manner and assessed independently. Results : 1. Thirty reports of clinical trials and two reports of meta-analyses concerning herbal medicine were collected and reviewed Among these reports three medical herbs were applied as topical medicine and others as internal medicine. 2. The western studies established NSAIDs or placebo as their control group. Five chinese reports established formulated herb pill(Ruanshnagshenjin pill) as their control group and Six did not establish a control group at all. 3. ACR was the most highly used diagnostic criteria in the western studies while the Chinese used their official criteria established by their government or the criteria of their text books. 4. 20 reports chose the Lequesne functional index, SHAQ, WOMAC OA index, AIMS, and their own unique scoring system as the criteria of analysing the effect. Others chose clinical symptoms, articular functions, and lab finding as their criteria. 5. 7 single herbs and 19 formulated herbs were studied. Among the formulated herbs, Achyranthes japonica was studied in 10 of the studies and Angelica gigantis Radix in 8, making them the most often studied herbs among the studies.

<P><B>Abstract</B></P> <P>A selective nonenzymatic glucose sensor was developed based on the direct oxidation of glucose on hierarchical CuCo bimetal-coated with a glucose-imprinted polymer (GIP). Glucose was introduced into the GIP composed of Nafion and polyurethane along with aminophenyl boronic acid (APBA), which was formed on the bimetal electrode formed on a screen-printed electrode. The extraction of glucose from the GIP allowed for the selective permeation of glucose into the bimetal electrode surface for oxidation. The GIP-coated bimetal sensor probe was characterized using electrochemical and surface analytical methods. The GIP layer coated on the NaOH pre-treated bimetal electrode exhibited a dynamic range between 1.0µM and 25.0mM with a detection limit of 0.65±0.10µM in phosphate buffer solution (pH 7.4). The anodic responses of uric acid, acetaminophen, dopamine, ascorbic acid, <SMALL>L</SMALL>-cysteine, and other saccharides (monosaccharides: galactose, mannose, fructose, and xylose; disaccharides: sucrose, lactose, and maltose) were not detected using the GIP-coated bimetal sensor. The reliability of the sensor was evaluated by the determination of glucose in artificial and whole blood samples.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Sensor is composed of hierarchical CuCo bimetal-coated with a glucose-imprinted polymer (GIP). </LI> <LI> The proposed sensor selectively detects glucose without interference from other saccharides and other organics. </LI> <LI> The reliability of the sensor was successfully evaluated using artificial and whole blood samples. </LI> </UL> </P>
