선광잔류물의 친환경적 처리 기술: 심해저광물자원개발시 발생하는 선광잔류물 특성 연구

망간단괴, 망간각, 해저열수광상 개발에서 필연적으로 발생하게되는 선광잔류물은 방대한 양과 잠재적인 독성으로 인해 관심이 증가하고 있지만, 아직까지 선광잔류물의 발생량, 물리·화학적 특성, 환경 유해성, 해양생태계에 미치는 영향 등에 관한 정보가 부족한 실정이다. 최근에는 선광잔류물의 친환경적인 처리 중요성이 인식되고, 그에 따른 저감/처리법이 강구되고 있다. 심해저 광물자원개발 시 선광잔류물이 선상에서 처리되지 못할 경우, 선광잔류물의 육상으로 운반 비용이 발생하고 육상 환경오염 문제를 해결해야하는 경우가 발생하게 된다. 따라서, 한국해양과학기술원에서는 1) 오염인자/환경영향, 2) 환경/생물 위해성 영향, 3) 입자 확산, 4) 선광, 5) 저감/처리(정화)를 친환경적인 선상에서의 선광잔류물 처리를 위한 주요 핵심 요소로 구분하여 선광잔류물의 유해성, 해양생태계에 미치는 영향, 오염 입자 확산 모델, 선광 및 정화처리 후보기술 등에 대한 연구를 수행하고 있다. 본 연구 결과는 향후 심해저광물자원 개발과정에서 발생할 수 있는 환경영향에 대한 과학적인 증거 확보를 통해 환경문제를 최소화 할 수 있는 연구 기반을 제시할 수 있고, 이는 다른 기원의 오염물 및 규제없이 방치되고 있는 육상 폐광산의 누출수 처리에도 적용할 수 있을 것이라 기대한다. Mine tailings, which are inevitably formed by the development of manganese nodules, manganese crusts, and hydrothermal seafloor deposits, have attracted attention because of their quantity and potential toxicity. However, there is a lack of data on the quantity of mine tailings being generated, their physicochemical properties, and their effects as environmental hazards and on marine ecosystems in general. The importance of treating mine tailings in an environmentally friendly manner has been recognized recently and related reduction/treatment methods are being considered. In the case of deep-sea mineral resource development, if mine tailings cannot be treated aboard a ship, the issue becomes one of the cost of transporting them to land and solving the problem of environmental pollution there. Therefore, the Korea Institute of Ocean Science and Technology conducted research on the harmfulness of mine tailings, their effect on marine ecosystem, the diffusion model of contaminated particles, and candidate purification treatment technologies based on five representative controlling factors: 1) effects of pollution /on the environment, 2) effects of environmental/ biological hazards, 3) diffusion of particles, 4) mineral dressings, and 5) reducing/processing mine tailings. The results of this study can provide a basis for minimizing environmental problems by providing scientific evidences of the environmental effects of mine tailings. In addition, it is also expected that these results could be applied to the treatment of pollutants of different origins and at land-based mining waste sites.
Hexokinase 방법을 이용한 Heparin 혈장과 NaF 혈장 시료의 혈당 분석치 비교

In this study, the two sampling methods for blood glucose measurement were evaluated in order to reduce pre-analytical error. For this purpose, glucose levels of Li-heparinized plasma (LHP) and Na-fluorinated plasma (NFP) in blood collected from healthy volunteers were determined by using routine hexokinase procedures. The percentage range of pre-analytical error was quantitated by comparing LHP glucose values with NFP glucose values according to delaying analytical time (0, 60, and 120 min). LHP glucose values were decreased by 6.6% in 60 min., 17.7% in 120 min, whereas NFP glucose values decreased by 1.1% in 60 min, 2.0% in 120 min. Therefore it may be recommended that the NFP sampling method should be used for routine blood glucose determination in diabetes mellitus diagnosis.

Hepatitis-B virus is a serious problem in Korea, and about 7 to 8 % of the populations are in carrier state. The only drugs currently approved for hepatitis-B infection is a -inteferon. However, the cure rate with this treatment is low. Some patients are unresponsive to the interferon, and some relapse when is stopped. Recently, Lamibudine, a novel cytosine analogue, exhibits potent anti-viral activity against hepatitis B virus. The effect of lamibudine treatment is good for almost all patient, but some patients showing refractorlness and the mutant HBV appearance. We studied for what kinds of tests are available for predict the response of lamibudine. HBeAg positive cases are 11.5 % in the HBV -PCR postive group and 0.0% in the HBV-PCR negative group. HBeAg neagtive cases are 88.5% in the HBV-PCR postive group and 100.0% in the HBV-PCR negative group. These results indicate that HBV-PCR test are more reliable for predict the viral state of HBV infection. So the 띠ral status evaluation(infectivity) for HBV infection by HBeAg assay is not recommended. Further studies recruiting on patient’s clinical courses and liver biopsy studies may helpful to determine the HBV viral status.

This Study has for its object to investigate the actual conditions of the quality control method of the Clinical Chemistry, Hematology and Immunology, and the quality control of the specimens and Automated Analysis of the five medical institutions in Jeju Island of 2000. The analysis methods, the type of a automatic system analyzer and quality control material make any difference with the other area. Besides, the Internal quality control applies only the X- R control chart and the VIS value produce stable results. The realities of a quality control is similar to the other areas. It is expected to run more Repeat analysis method in the hematological quality control. It is also expected a variable method to the side of quality control.
Glucose Oxidase를 이용한 혈당 정량법에 Ascorbic acid가 미치는 영향에 대한 연구
문인경 제주한라대학 2002 論文集 Vol.26 No.-
The GOD method using blood glucose analysis has been announced interfering above 25mg/㎗ in blood consistency of the ascorbic acid. The 5 sera groups which are divided into each consistency of 5, 15, 25, 35 and 45mg are analyzed with the GOD method, and researched the influence of each response. A theory which the GOD method is influenced only above 25mg of the ascorbic acid's consistency should be re-examined, according to this research, the GOD method is influenced 2.73% under the 5mg of the ascorbic acid's consistency.
