This study is presented the improvement techniques of artificial wetland, one of micro-ecosystem developed to promote bio-diversity in urban areas, through studies of problem in cases. To this end, based on instances found in broad and importance which is development method of ecological park, wetland and micro-ecosystem at cases was proved the effect of techniques. There was no monitoring result and biological lacking about biological form in urban areas in korea. But this study selected the subject which it built up until the present time and it was presumes development possibility site. So this study showed techniques to promote bio-diversity. Key result of this study are as follows. (1) There is the problem of the living environment for creatures. The artificial embankment is necessary to various water depths and considering of the living of aquatic life. It is an important factor for the ability of activity place and prevention of soil erosion for activities of aquatic insects and young fish as well as the growth of aquatic plants. Therefore, as create of the embankment must considering that form of embankment, various grade, soil stability, food-plant and as well as the plant by water to clean . (2) It is necessary for making observation way to protection. Recently, this problem must consider because of ecological park stand out in bold relief. As a result, the ecological park must accept many people to use. Therefore, nature get damaged. Until now, cases are developed deck and way for observation too accessible. So a soil environment has been change for the worse and caused soil compaction. It was menaced the living environment for creature. Therefore, suitable pattern of observation way and areas for protection through the control should be consider to protect of living environment for creatures. (3) Cases presented is lack model of living environment for creature. In such a case of a forward nation, there is studying about ecological model to promote bio-diversity even detailed part. To example, stone-constructed, to placement a log, to built of a grass-roofed house(a small cottage), it is induce a micro-living thing by create porous environment. Therefore, we must continually study for allurement a living thing at the place-constructed in urban areas. (4) Environment education program's development are more earnest are urgent. It is most important works. Therefore, study have to going afterward. The present state of artificial wetland and eco-pond were not development of program. So it is raise the problem. Environment education by placement of guide map or book and a volunteer in the field is a practice way of a narrow means. Also development program is urgent to aware important of environment and development program and training for environmental specialist have to preceding. As a result of development method groping should be sponsored education of special and efficacious.

安文圭,鄭容子 경성대학교 1985 부산수산대학 논문집 Vol.6 No.2

Ion pair compounds between prifinium bromide and acid dyes were extracted from the aqueous solution into organic phase and determined colorimetrically each of the maximum absorption wavelength. Diprotic acids such as Bromphenol blue, Bromcresol green, Bromthymol blue and monoprotic acids such as tetrabromo phenolphthalein ethyl ester and dichlorophenol indophenol were used as color forming agents. The intensity of the color was measured spectrophotometrically. The absorbance showed a linear relationship to the concentration of prifinium bromide in the aqueous solution over the range of (1∼5)×?? M for BPB, (2∼6)×?? M for BCG and BTB, and (1∼5)×?? M for TBPE and DCIP. A singly charged TBPE and DCIP anion was found to be extracted with prifinium bromide as 1:1 associates in organic phase, while in the case of diprotic acid dyes was extracted 2:1 associates. The analysis was carried out as follows; buffer solution 5㎖, acid dye solution (5×10??) 3㎖and prifinium standard solution (5×10??) (1∼5)㎖ are poured into a sep aratory funnel. After diluting the mixture to 50㎖ with water, 10㎖ of chloroform is added. After the solution shaked for 3 min, the organic phase is centrifuged to remove droplets of water. The absorbance of the extracts is measured at each maximum absorption wavelength, using a reagent blank or water as reference.

강종성,홍정희,임정미,이용문,장재연 충남대학교 약학대학 의약품개발연구소 1999 藥學論文集 Vol.15 No.-

방향족 탄화수소인 tnmethylbenzene (TMB)은 그 사용량이 늘어갈 뿐 아니라 직업적으로 폭로되는 양도 증가하고 있으므로 생물학적 모니터링 및 흡수, 대사, 배설에 관한 연구가 중요시되고 있다. 일반적으로 TMB는 간의 산화효소에 의해 하나의 메틸기가 산화되고 이것은 glycine과 포합되어 배설되는 것으로알려져 있다. 본 연구에서는 1,2,4-TMB의 대사체를 합성하고, 모세관의 전기영동법으로 분석할 수 있는 방법을 개발하였다. 모세관 전기영동법으로 흰쥐의 뇨 중에서 1,2,4-TMB의 대사체인 3,4, 2,4, 2,5-dimethylbenzoic acid 및 3,4 2,4 2,5-dimethylhippuric acid를 분석하기 위하여 내경 75㎛, 총길이 35cm (검출기까지 29cm)인 용융실리카 모세관을 15℃로 유지하면서 양단에 10kV의 전압을 걸어주고, 전해질로는 15mM β-CD, 3% 2-프로판올을 포함하는 01m 인산완충액 (pH 7)을 사용하였으며, 검출신호는 UV 210nm와 254nm에서 동시에 모니터링하였다. 뇨 시료의 분석 결과 배설된 1,2,4-TMB의 대사체의 상대량은 3,4-이성질체가 56.&%, 2,4-이성질체가 30.5%, 2,5-이성질체가 12.8%였다. 이 방법은 노동자의 뇨 분석에도 적용될 수 있을 것으로 생각된다. The metabolites of 1,2,4-trimethylbenzene (TMB) were synthesized and determined by capillary electrophoresis (CE). The optimum conditions of CE for the separation and determination of 3,4-, 2,4-, 2,5-dimethylbenzoic acid and 3,4-, 2,4-, 2,5-dimethylhippuric acid from the rat wine were as following: the fused silica capillary(75μm i.d. X 36 cm length, 29 cm to detector) was used and kept at 15℃ The applied voltage was 10kV and compounds were detected at UV 210 nm and 254 nm. The running electrolyte was 0.1 M phosphate buffer (pH 7) contalI1ing 15 mM of β -CD and 3% of 2-propanol. The relative amount of the metabolite of 1,2.4-TMB in the rat urine was 56.7% of 3,4-isomer, 30.5% of 2,4-lsomer and 12.8% of 2,5-isomer. This method can be applied to the analysis of TMB-metabolites in human wine.

HHV-8 virus is known to be associated with Kaposi's sarcoma (KS) in HIV seropositive patients and its seroprevalence has geographic difference, In South Korea, incidence of KS is low not only in general population but also in HIV patients compared to other countries, It is speculated that low seroprevalence of HHV-8 has contributed to the low incidence of KS in South Korea. We examined the seroprevalence of anti HHV-8 IgG of HIV seronegative health care workers in one University hospital. Enzyme-linked immunosorbent assay(ELISA) was used for diagnosis. One person (0.6% 1/164) was seropositive, six were equivocal (3.7%,6/164) and 157 people were seronegative (95.73%, 157/164). This study revealed that seroprevalence of HHV-8 in general population was. low in South Korea. Further studies are needed to be carried out to evaluate the low HHV-8 seroprevalence in Korea.
