엄태윤,김인환,이창헌,강창희,이시은,이원,임재희 濟州大學校 基礎科學硏究所 1994 基礎科學硏究 Vol.7 No.1

Aresenazo I-XAD-2 킬레이수지를 합성하고 이 수지에 대한 U(VI)이온의 흡착 거동을 조사 검토하였다. 킬레이트수지는 Arsenazo I 킬레이트제와 Amberlite XAD-2의 디아조늄짝지움 반응에 의해서 합성하였으며 원소 분석법과 적외선 분광법으로 확인하였다. U(VI)이온흡착의 최적 조건을 찾기 위해서 pH, U(VI) 이온농도와 진탕 시간에 관해서 조사하였다. U(VI)이온에 대한 킬레이트수지의 전체 흡착능은 pH 4.0∼4.5 범위에서 0.39mmol U(VI)/g resin이었고, pH값이 증가함에 따라 흡착능이 증가하였다. Arsenazo I-XAD-2 킬레이트 수지에 대한 U(VI)이온의 흡착 메카니즘은 U(VI)이온과 H+ 이온 사이의 경쟁반응임을 확인하였다. 컬럼법으로 구한 U(VI) 이온의 돌파점 부피와 전체 흡착능은 각각 600ml, 0.38mmol U(VI)/g resin 이었다. 3M HNO₃와 3m Na₂CO₃의 탈착용액을 사용하여 구한 회수율은 90∼96%였다. 따라서 본 연구에서는 합성한 Arsenaso I-XAD-2 킬레이트수지는 자연수 바닷물 중에 함유된 U(VI)이온의 분리와 농축에 매우 유용함을 알았다. Some sorption behaviors of U(VI) ion on Arsenazo I-XAD-2 chelating resin were investigated. This chelating resin was synthesized by the diazonium coupling of Amberlite XAD-2 resin with Arsenazo I chelating reagent and characterized by elementary analysis method and IR spectrometry. The optimum conditions for the sorption of U(VI) ion were examined with respect to pH, U(VI) ion concentration and shaking time. Total sorption capacity of this chelating resin on U(VI) ion was 0.39 mmol U(VI)/g resin in the pH range of 4.0∼4.5. This chelating resin was showed increased sorption capacity on the increased pH value. It was confirmed that sorption mechanism of U(VI) ion on the Arsenazo I-XAD-2 chelating resin was competition reaction between U(VI) ion and H+ ion. Breakthrough volume and overall capacity of U(VI) ion measured by column were was 600ml and 0.38 mmol U(VI)/g resin, respectively. The desorption of U(VI) ion was showed recovery of 90∼96% using 3M HNO₃and 3M Na₂CO₃as a desorption solution. The separation and concentration of U(VI) ion from natural water and sea water was performed successfully by Arsenazo I-XAD-2 chelating resin.

The main findings through this study are summarized as conclusion below ; When dredge soil (ill to sea area, suspended soil widely spread from main area to north of ga-duk island without the pollutant's fence, Especially, the total area of ung-dong bay is more than 20㎎/ℓ as SS concentration and the pollution of north of gaduk Island is considerable. Therefore dredge was needed the pollutant's fence, Consequently the only that main area is more than 20㎎/ℓ as SS concentration, decreasing of pollution is explicitly acknowledged on the ocean because the others except for dredged area is less than 2∼8㎎/ℓ as SS concentration with the pollutant's fence. It is only considered SS concentration of dredge soil, because concentration of BOD, TN and TP were very lower than not concentration. Heavy metal concentration of the dredge soil is lower than not only the standard of heavy metal in the sea-water but heavy metal concentration including sediments with dredged area. It is decided that the polluted surrounding area has been little by heavy metal.

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

梁在炫,嚴泰允 단국대학교 1984 論文集 Vol.18 No.-

Some characteristics of Model TSN 206 SA Mass Spectrometer, especially, on the variation of ion population as a function of time at the ion source, response time of the magnetic field and stability of the field after step scanning at peaks have been investigated and the following results are obtained. 1) Magnetic field response is fast enough for a general experimental purpose so that waiting time longer than 50μsec. after step scanning at peaks gives sufficient accuracy. 2) Integration time is more important than waiting time and the former should be longer than 1sec. in order to have ordinary analytical accuracy. 3) Built-in clock system is designed such that it's increment is 0.2sec. For short integrating time experiment, it is very important that the integration should be set at duration of integar multiple of 0.2sec. 4) In order to obtain more accurate isotope ratio, data processing program must be modified considering the pattern of tatal ion population variation during a measurement in the ion source of the system.

Purpose: The change of the marginal bone around dental implants have significance not only for the functional maintenance but also for the esthetic success of the implant. The purpose of this study was to investigate the load transfer of internal conical joint type implant according to marginal bone resorption by using the three-dimensional finite element analysis model. Materials and methods: The internal conical joint type system was selected as an experimental model. Finite element models of bone/implant/prosthesis complex were constructed. A load of 300 N was applied vertically beside 3 mm of implant axis. Results: The pattern of stress distribution according to marginal bone resorption was similar. The maximum equivalent stress of implant was increase according to marginal bone resorption and the largest maximum equivalent stress was shown at model of 1 mm marginal bone resorption. Although marginal bone loss more than 1mm was occurred increasing of stress, the width of the stress increase was decreasing. Conclusion: According to these results, the exposure of thin neck portion of internal conical joint type implant is most important factor in stress increasing. 연구 목적: 지금까지 성공적인 임플란트 치료를 위해 많은 연구가 진행되어 왔으며, 임플란트 주변 골 흡수 현상에 대한 연구는 매우 관심이 높은 분야 중 하나이다. 이에 본 연구에서는 삼차원 유한요소응력분석을 이용하여 변연골 흡수가 내측연결 임플란트 매식체의 기계적 안정성에 미치는 영향을 간접적으로 확인하고자 하였다. 연구 재료 및 방법: 악골에 식립된 내측연결 형태의 임플란트 매식체에 티타늄 소재의 임플란트 지대주를 지대주 나사로 연결하고 상부에 금합금관을 장착하는 삼차원 유한요소모형을 설계하였다. 0, 1, 2, 3 mm의 변연골 흡수 상태를 적용하고, 교합면 중심에서부터 3 mm 편측에 300 N의 수직 하중을 가하여 임플란트 매식체에 발생하는 최대 주응력을 계산하였다. 결과: 유한요소분석결과 변연골 흡수에 따른 임플란트 매식체의 최대 주응력 분포는 유사한 양상을 보였으며, 임플란트 매식체 상단에서 가장 높은 응력 집중이 나타났다. 최대 주응력은 처음 1 mm 변연골 흡수를 가정하였을 때 가장 크게 증가하였고, 이후 변연골 흡수가 증가할수록 응력은 증가하였지만 응력 증가의 폭은 감소하는 경향을 보였다. 결론: 이러한 결과로부터 내측연결 임플란트에서 매식체 두께가 얇은 경부의 노출은 변연골 흡수로 인한 응력 증가에 가장 큰 원인임을 알 수 있었으며, 매식체의 변형, 균열 및 파절 등의 기계적 실패를 감소시키기 위해서는 이에 대한 외과적, 보철적 고려가 필요할 것으로 생각된다.

위의 저도 MALT 림프종은 H. pylori 제균 후에 60∼90%가 관해를 보이는 것으로 알려져 있으나 고도 MALT 림프종은 H. pylori 제균 만으로는 치료가 부족한 것으로 알려져 있다. 그러나 최근에 위의 고도 MALT 림프종에서도 H. pylori 제균 치료를 통해 관해에 이른 사례들이 보고 되었고, 저자들도 고도 MALT 림프종 환자에서 H. pylori 제균 치료를 통하여 내시경적 및 조직학적 완전 관해에 도달한 증례를 경험하여 이를 보고하는 바이다. Low grade MALT lymphoma of stomach is associated with H. pylori infection in more than 90% of cases, and eradication of H. pylori leads to regression of the low grade MALT lymphoma in 60∼90% of cases. On the contrary, high grade MALT lymphoma is thought to be independent from H. pylori for growth and usually is thought to require antitumor chemotherapy. However, there have been recent reports of high grade MALT lymphoma regressing after H. pylori eradication. We experienced and are reporting a case of high grade MALT lymphoma arising in the background of low grade MALT lymphoma that showed complete regression after H. pylori eradication.
