Boiled, broiled, deep fried, pan fried 등의 방법으로 조리된 조기와 돼지고기의 50% methanol 추출물에 S9 mix를 첨가한 군, S9 mix를 첨가하지 않은 군, 그리고 nitrite를 처리한 군을 Salmonella typhimurium TA98과 TA100으로 Ames test를 실시하여 돌연변이원 형성을 검토한 결과는 다음과 같다. 1. S9 mix를 첨가하지 않은 조기와 돼지고기는 original weight 0.0125 g과 0.1 g사이의 농도 구간에서 돌연변이 원성을 보였다. 2. S9 mix 첨가시 조기와 돼지고기의 돌연변이원성은 모든 농도 구간에서 S9 mix를 첨가하지 않은 경우보다 2∼5배 정도 증가하여 간접 돌연변이원이 존재함을 확인하였다. 3. TA98과 TA100에 대한 돌연변이원성은 모든 조리법에서 조기보다 돼지고기가 더 높았고, 특히 pan fried법의 경우 S9 mix의 첨가시 돌연변이원성이 매우 높게 나타났다. 4. 조기와 돼지고기의 모든 조리법에서 nitrite 처리시 TA98과 TA100 모두 돌연변이원성이 증가하여 직접돌연변이원임을 나타냈고, 특히 TA100보다 TA98에서 돌연변이원성이 더 높은 것으로 나타났다.

국제수로기구(IHO)는 항해안전과 해양환경보호를 위한 적절하고 효율적인 수로 데이터 및 정보사용을 지원하기 위해, 전자 수로 데이터를 위한 S-100 표준을 개발하였다. 이전 모델인 S-57의 경우, 차세대 전자해도(ENC) 생산 조건의 바탕이 되기에는 비효율적이라고 판단되었다. S-100 표준의 가장 핵심적인 특징은 표준화 등록소와 그것을 이루고 있는 등록부의 활용이다. 이 온라인 등록소는 편리하게 실제 항해 시스템에 적용될 수 있는 세계 공통의 표준을 제공한다. 현재는 IHO가 유일한 등록소를 소유하고 있으며, 도메인 전문가들에게 접근이 허용되고 있다. 그러나 S-100 표준이 국제기구에 의해 운영되는 국제 표준인 만큼, 필요 시 즉각적인 데이터의 수정 및 갱신이 불가능하고 시간 소요가 많다. 따라서 국내 사용자와 항해자들의 항해 안전성을 고려하여, 독자적인 표준기술개발을 위한 개별적인 등록소가 국내에도 자체적으로 필요하다고 판단하였다. 이 연구는 IHO에서 편찬된 S-99를 바탕으로 하여, 정의 및 수로데이터를 제공하는 목적에 부합하는 웹사이트 디자인을 통해 등록소를 설계하였다.

A study was undertaken to examine the effect of curing agents on the stability, curing and segregation of R plasmid pSL100. And also the stability, transfer frequency, and recombination of its segregants obtained from curing agent treatment were studied. Ethidium bromide, acridine orange, and mitomycin-C were used as curing agent. The results obtained were as follows ; 1. The curing agent ethidium bromide, acridine orange, and mitomycin-C were not effective for curing the multiple antibiotic resistant determinant of pSL100 in Salmonella typhimurium and Escherichia coli. However, they induced plasmid segregation with high frequency in S.typhimuruim LT-2strains. TcApSmCm, TcSmCmKm, TcApCm, TcAp, TcKm, Tc segregants were obtained. 2. The resistant markers of the segregents were transferred to S.typhimurium LT-2 strains with high frequencies whereas they were transferred to E.coli K-12 only with low frequencies. 3. The transconjugants obtained from conjugation between two different S.typhimurium segregants were similar to the phenotype of the original R factor pSL100 and the resistant markers were transferred to the S.typhimurium LT-2 or E.coli strain with equal frequencies, indicating that they are recombinants. 4. The transconjugants obtained from conjugation between pSL100 segrgants and pKM101, or pBR322 possessed the resistant markers of the two parental plasmids and they were transferred to both S.typhimurium and E.coli K-12 strains with the same frequencies and maintained stably, suggesting that they are also recombinants. 5. The recombinant pSL100 could be also obtained in rec A-strains of E.coli, suggesting that the gene function of rec A is required for the recombination of pSL100 segregants in E.coli.

본 논문은 100 Gb/s급 광통신 시스템을 위한 반복적인 Bose-Chaudhuri-Hocquenghem (BCH) 부호와 고성능 복호기 구조를 보여준다. 제안된 구조는 고속 데이터 처리율뿐만 아니라 뛰어난 오류정정능력을 보여준다. 제안된 6회 반복 i-BCH 복호기는 메모리 기반의 인터리브 기술을 이용하였으며 6번의 반복 복호시 $10^{-15}$ post-FEC Bit Error Rate(BER) 기준 9.34 dB의 강력한 Net Coding Gain(NCG) 성능을 제공한다. 제안된 고성능 i-BCH 복호기의 구조는 90-nm CMOS 공정을 사용하여 합성한 후 수행한 성능 분석 결과 430 MHz의 동작 속도와 100 Gb/s의 데이터 처리율을 갖는다. 따라서 100 Gb/s급 광통신시스템을 위한 차세대 순방향 오류정정 구조에 적용할 수 있다.

Objectives This experimental study was performed to investigate the continuous anti-bacterial potency of Coptidis rhizoma extract on cultivation of Staphylococcus species(S. aureus, S. epidermidis) that induce eye disease. Methods Minimal inhibitory concentration(MIC) was measured by dropping to $50{\mu}l$ diluted Coptidis rhizoma extract(100%, 10%, 1%, 0.1%) on S. aureus, S. epidermidis that were cultivated from 2 to 6 days. Anti-bacterial potency was measured by the size of inhibition zone with change of volume($20{\mu}l,\;30{\mu}l,\;40{\mu}l,\;50{\mu}l$). Results 1. Anti-bacterial potency of Coptidis rhizoma extract on S. aureus was appeared in 100%, 10% and was the same as anti-bacterial potency of 2 days and 6 days. Anti-bacterial potency with change of volume(100%) was increased in propotion to increase volume on all samples. Anti-bacterial potency with change of volume(10%) was increased in propotion to increase volume on all samples except $20{\mu}l$. Anti-bacterial potency of Coptidis rhizoma extract on S. aureus was appeared continuous. 2. Anti-bacterial potency of Coptidis rhizoma extract on S. epidermidis was appeared in 100%, 10% and was the same as anti-bacterial potency of 2 days and 6 days. Anti-bacterial potency with change of volume(100%) was increased in propotion to increase volume on all samples. Anti-bacterial potency with change of volume(10%) was appeared in $50{\mu}l$. Anti-bacterial potency of Coptidis rhizoma extract on S. epidermidis was appeared continuous. Conclusions Anti-bacterial potency of Coptidis rhizoma extract on cultivation of S. aureus & S. epidermidis was showed continuous.

Methods : Minimal inhibitory concentration(MIC) was measured by dropping to 50${\mu}$l diluted Sean-tang(100%, 10%,1%, 0.1%) on S. aureus, S. epidermidis that were cultivated from 2 to 6 days. 1. Anti-bacterial potency was measured by the size of inhibition zone with change of volume(20${\mu}$l, 30${\mu}$l, 40${\mu}$l, 50${\mu}$l). Results : 1. Anti-bacterial potency of Sean-tang on S. aureus was appeared in 100% and increased on 6 days. Anti-bacterial potency with change of volume was increased in propotion to increase volume. Anti-bacterial potency of Sean-tang on S. aureus was appeared continuous. 2. Anti-bacterial potency of S. epidermidis was appeared in 100%, 10%, 1% on 2 days and in100%, 10% on 6 days. In 100% Sean-tang, Anti-bacterial potency of 6 days was increased, in 10%, 1%, Anti-bacterial potency of 2 days was increased. Anti-bacterial potency with change of volume was increased inpropotion to increase volume and increased on 6 days, but bacteria was increased. Anti-bacterial potency Sean-tang on S. epidermidis wasn't appeared continuous. Conclusions : Anti-bacterial potency of Sean-tang on cultivation of S. aureus was showed continuous, but on cultivation of S. epidermidis was not showed continuous.
