The main goals of the study were to investigate the sediment quality and trace metal distribution in sediment of Kwangyang Bay, south coastal of Korea. Surface sediment sampling were performed in November, 2000 and February and March, 2001. The concentration of H₂S, IL and COD in sediment were measured by a manual of the Department of Marine Environment of Korea. The extracted trace metals Fe, Cu, Cd, Pb, and Zn in sediments mean analyzed by the flame atomic absorption spectrophotometer with an instrument of model Shimadzu AA-6701F. H₂S, IL and COD in the surface sediment were 1.3 mg/g, 5.9 % and 15.0 mg/g, respectively. The mean content of Fe, Cu, Cd, Pb and Zn were 1523 mg/kg, 4.799 mg/kg, 1.321 mg/kg 9.285 mg/kg and 9.353 mg/kg, respectively. All of these measured trace metals level were over the other reported trace metal level in sediment of coastal area. According to histograms, the content of H₂S, IL and COD and trace metals in sediment of this study were affected by artificial activities rather than natural process.

Purpose : In order to study the effectiveness of East-West pain treatment on central poststroke pain(CPSP), we evaluated its effect on alleviation of pain and rehabilitation of CPSP Patients who were treated with electroacupuncture and west pain treatment for four weeks. Methods : Twenty four patients diagnosed by their pain characteristics of central pain from stroke were treated with sympathetic nerve block, gabapentin, amitriptyline, and electroacupuncture for four weeks. Pain intensity through the visual analogue scale(VAS), and improvements of mobility and rehabilitation through the modified Barthel index(MBI) and Rankin scale(RS), respectively, before and after pain treatment were also assessed. Results : VAS pain scores were significantly improved from 7.7±1.7 to 4.4±2.0 with pain treatment(p<0.05). In accordance with improvement of pain scores, RS and MBI scores were also improved from 2.88±0.95 to 2.13± 1.01 and from 83.0± 16.9 to 94.7±9.5(p<0.05), respectively, with pain treatment(p<0.05). Conclusions : It was suggested that the active pain treatment was contributed to the rehabilitation of CPSP patients, resulting in improvement of quality of life of CPSP patients. Futhermore, East pain treatment in combination with West pain treatment may be useful modality to alleviate CPSP.

Dealkylation of m-diisopropylbenzene (m-DIPB) was studied on various zeolite catalysts which have different pore structures. The very low dealkylation activity was observed on MFI zeolite because of its small pore size. The m-DIPB low conversions of MOR and FAU zeolites were due to severe deactivation of the catalysts by carbon deposites. On the other hand, the high conversion and the low deactivation in the m-DIPB dealkylation were observed on BEA zeolite with bent pores and MWW zeolite with pillow-type pores. In particular, the MWW zeolite shows a very high conversion, because the polymerization of m-DIPB resulting to carbon deposites is suppressed by sharing one m-DIPB molecule per unit pore. The high selectivity for benzene on MWW zeolite is explained by long retention time of reaction intermediate inducing consecutive dealkylation.

We studied the oxidation of docosahexaenoic acid(DHA: C22: 6ω-3). β-Cyclodextrin(CD) inclusion complexes(ICs) of DHA were prepared with antioxidant such as α-tocopherol and BHT, and microcapsulated with Curdlan and Pullulan. Identification of their structural features of ICs were observed with the use of SEM, FTR, and XRD. Methods for quantitative analysis of DHA were used: TLC scanning method and TBARS(Thiobarbituric acid reactive substance) method. As a result, we observed the formation of ICs and estimated antioxidant effect. In this work, loading efficiency of DHA in ICs was about 25%, and the antioxidant effect of α-tocopherol was higher than that of BHT. When ICs containing DHA was microcapsulated with curdlan and pullulan, the loading efficiency was less than 5%.

Evaluation of a hybrid constructed wetland for treating domestic sewage from individual housing units surrounding agricultural villages in South Korea

Seo, Dong Cheol,DeLaune, Ronald D.,Park, Woo Young,Lim, Jong Sir,Seo, Jeoung Yoon,Lee, Do Jin,Cho, Ju Sik,Heo, Jong Soo Royal Society of Chemistry 2009 Journal of environmental monitoring Vol.11 No.1

<P>The treatment efficiency of 2- and 3-stage constructed wetlands (CWs) was evaluated for treating domestic sewage from houses surrounding agricultural villages. The optimum depth of filter media was 90 cm. The optimum volume ratio of vertical flow (VF) and horizontal flow (HF) beds was 1:2, and the optimum filter medium was broken stone in the VF-HF 2-stage hybrid CWs. Based on the above optimum conditions, removal efficiency of biochemical oxygen demand (BOD), chemical oxygen demand (COD), suspended solids (SS), total nitrogen (T-N), and total phosphorus (T-P) were 99, 98, 99, 68, and 72%, respectively. However to utilize constructed wetlands (CWs) for treating domestic sewage for an individual house, would require downsizing of the 2-stage hybrid CWs. In addition, the low removal efficiency of T-N and T-P in 2-stage hybrid CWs would require improvements necessary to meet acceptable water quality discharge standards. Thus, to reduce the CWs’ area and improve the T-N and T-P removal efficiencies, VF-HF 2-stage hybrid CW was modified into VF/HF(I)-HF(II) and VF/HF(I)-HF(III) 3-stage hybrid CW. The optimum reduced size of 3-stage hybrid CW was the VF/HF(I)-HF(II) configuration which also increased T-N removal. Using this system, removal efficiency of BOD, COD, SS, T-N, and T-P were 99, 98, 99, 83, and 75%, respectively. In VF/HF(I)-HF(II) CW, the removal velocity of BOD, COD and SS was rapid on the order of VF (1<SUP>st</SUP> stage) ≫ HF(II) (3<SUP>rd</SUP> stage) ≥ HF(I) (2<SUP>nd</SUP> stage), VF (1<SUP>st</SUP> stage) ≫ HF(II) (3<SUP>rd</SUP> stage) > HF(I) (2<SUP>nd</SUP> stage) and VF (1<SUP>st</SUP> stage) ≫ HF(I) (2<SUP>nd</SUP> stage) > HF(II) (3<SUP>rd</SUP> stage), respectively. The removal velocity of T-N and T-P in VF/HF(I)-HF(II) CWs was rapid on the order of HF(I) (2<SUP>nd</SUP> stage) > HF(II) (3<SUP>rd</SUP> stage) ≥ VF (1<SUP>st</SUP> stage) and VF (1<SUP>st</SUP> stage) > HF(I) (2<SUP>nd</SUP> stage) > HF(II) (3<SUP>rd</SUP> stage), respectively.</P> <P>Graphic Abstract</P><P>To effectively treat domestic sewage from individual houses surrounding agricultural villages, the optimum hybrid constructed wetlands was demonstrated to be the VF/HF(I)-HF(II) 3-stage constructed wetlands configuration. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=b806017g'> </P>

Report of the Korean Association of External Quality Assessment Service on Cardiac Marker Testing (2016–2020)

Jong Do Seo,Hanah Kim,Yeo-Min Yun 대한임상검사정도관리협회 2021 Journal of Laboratory Medicine And Quality Assuran Vol.43 No.4

Cardiac marker tests are useful tools to diagnose acute coronary syndrome and predict its prognosis; therefore, reliable test results are required. The Korean Association of External Quality Assessment Service has conducted a proficiency test program for cardiac marker tests twice a year since 2016 using low- and medium-level pooled serum and high-level commercial quality control (QC) material. This report summarizes the results of the proficiency tests performed from 2016 to 2020. The number of participating laboratories increased from 321 in 2016 (1st trial) to 476 in 2020 (2nd trial). Items that showed the highest increase in participation during this period were tests for N-terminal-pro brain natriuretic peptide (NT-proBNP) (+86.2%) and creatine kinase-myocardial band (CK-MB) mass tests (+73.2%), whereas the corresponding BNP (–6.6%) and CK-MB activity (–26.5%) items were decreased. The most and least commonly tested items were CK-MB mass in 417 laboratories, and CK-MB activity in 25 laboratories, respectively. The coefficients of variation (CVs) differed among the manufacturers, and among different instruments from the same manufacturer. In 2020, during the 2nd trial, the lowest CV was confirmed in the troponin T test using the same manufacturer’s instruments, for the medium-level pooled serum sample. However, the CV for high-level commercial QC material was higher. Similarly, the NT-proBNP test for commercial QC material showed higher CV compared to pooled serum. These results are considered to originate from the non-commutability of commercial QC material; therefore, obtaining the commutability of the materials for the external quality assessment program is required.

Jasmonic acid carboxyl methyltransferase : a key enzyme for jasmonate-regulated plant responses

Seo, Hak Soo,Song, Jong Tae,Cheong, Jong-Joo,Lee, Jong Seob,Choi, Yang Do 이화여자대학교 세포신호전달연구센터 2001 고사리 세포신호전달 심포지움 Vol. No.3

Methyl jasmonate is a plant volatile that acts as an important cellular regulator mediating diverse developmental processes and defense responses. We have cloned the novel gene JMT encoding a S-adenosyl-L-methionine: jasmonic acid carboxyl methyltransferase from Arabidopsis thaliana. Recombinant JMT protein expressed in E. coli catalyzed the formation of methly jasmonate from jasmonic acid with Km value of 38.5 mM. JMT RNA was not detected in young seedlings but was detected in rosettes, cauline leaves and developing flowers. In addition, expression of the gene was induced both locally and systemically by wounding or methyl jasmonate treatment. This result suggests that JMT can perceive and respond to local and systemic signals generated by external stimuli, and that the signals may include methyl jasmonate itself. Transgenic Arabidopsis overexpressing JMT had a 3-fold elevated level of endogenous methyl jasmonate without altering jasmonic acid content. The transgenic plants exhibited constitutive expression of jasmonate-responsive genes including VSP and PDF1.2. Furthermore, the transgenic plants showed enhanced level of resistance against the virulent fungus Botrytis cinerea. Thus, our data suggest that the jasmonic acid carboxyl methyltransferase is a key enzyme for jasmonate-regulated plant responses. Activation of JMT expression leads to production of methyl jasmonate that could act as an intracellular regulator, a diffusible intercellular signal transducer, and an airborne signal mediating intra- and inter-plant communications.
