Headspace-solid phase microextraction 방법에 의한 DCAA & TCAA 분석에 관한 연구
조덕희,오성근 대한상하수도학회 2003 상하수도학회지 Vol.17 No.6
Water chlorination for disinfection purposes leads to the formation of haloacetic acids (HAAs). In this study, headspace solid-phase microextraction (HSSPME) was studied as a possible alternative to liquid-liquid extrmon for the analysis of HAAs in drinking water. The method involves direct derivatization of the acids to their methyl esters without methyl tert-butyl ether (MTBE) extraction. Experimental parameters such as 2㎝-50/30㎛ divinylbenzene/carboxen/polydimethylsiloxane fiber, sulphuric acid of 1㎖, methanol of 3ml, derivatization temperature of 50T, derivatization time of 2hrs, sodium chloride salt of 10g , extraction time of 30minutes, extraction temperature of 20℃ and desorption time of lminute at 260℃ were selected in optrmal experimental conditions for the analysis of haloacetic acids. The linearity (r²) for DCAA and TCAA is 0.9981 and 0.9997 when analyte concentration ranges from 1 to 4㎍/l, respectively. The relative standard deviations (%RSD) for DCAA and TCAA were 3.5 and 2.1% for concentration of 10㎍/l (n=5), respectively. The limits of detection (LOD) were 0.05 and 0.1㎍/l. The results of HAA2 from the survey of Seongnam drinking water samples showed that the highest concentration of HAA2 (DCAA + TCAA) were 30.04㎍/l which was well within the Korean drinking water quality standard of 100㎍/l. It can be concluded that HSSPME technique with direct derivatization has a great potential for the analysis of drinking water.
Ferrite-Bainite dual phase 강의 피로균열진전 특성 평가

With the recent increase in size of ships and offshore structures, there are more demand for thicker plates. As the thickness increases, it is known that fatigue life of the structures decrease. To improve the fatigue life, post weld treatments techniques, such as toe grinding, TIG dressing and hammer peening, are typically employed. However, these techniques require additional construction time and production cost. Therefore, it is of crucial interest steels with longer fatigue crack growth life compared to conventional steels. This study investigates fatigue crack growth rate (FCGR) behaviours of conventional EH36 steel and Ferrite- Bainite dual phase EH36 steel (F-B steel). F-B steel is known to have improved fatigue performance associated with the existence of two different phases. Ferrite-Bainite dual phase microstructures are obtained by special thermo mechanical control process (TMCP). FCGR behaviours are investigated by a series of constant stress-controlled FCGR tests. Considering all test conditions (ambient, low temperature, high stress ratio), it is shown that FCGR of F-B steel is slower than that of conventional EH36 steel. From the tensile tests and impact tests, F-B steel exhibits higher values of strength and impact energy leading to slower FCGR.
한국과 일본의 역사 교과서 재판을 통한『교육부장관』의 검정 교과서 수정명령권 분석
김덕근 ( Deok Geun Kim ) 대한교육법학회 2013 敎育 法學 硏究 Vol.25 No.1
한국과 일본의 역사 교과서 재판을 통한 교육부장관의 검정 교과서 수정명령권에 대 하여 분석해 본 결과는 다음과 같다. 첫째, 법률유보원칙 위배 여부에 대하여, 하급심에서는 검정 교과서에 대한 교육부장 관의 포괄적 수정명령권을 인정하였다. 그러나 대법원은 교육부장관의 오기·오타·통 계 등 형식요건 부분의 수정명령권을 인정하였으나, 교육적합성과 내용적합성에 대한 부분은 일정한 한계가 있음을 지적하였다. 이는 우리나라 법원의 태도가 점차적으로 수 정에 있어서 까다로운 절차를 규정한 일본에 가까운 방향으로 나아감을 의미한다. 둘째, 저작자의 원고적격 문제에 대하여, 교육부장관의 검정 교과서 수정명령권이 발행 자에게만 미친다면 저작자들의 입장에서는 자신들이 쓴 교과서에 본인들의 사상, 철학, 학 문적 견해 등이 전혀 다른 의도로 표현될 개연성이 높다. 따라서 교과서의 저작자는 직접 교육부장관을 상대로 그 수정명령의 취소를 구할 법률상 이익이 있는 것으로 판단된다. 셋째, 교육과학기술부 심의절차 흠결의 위법 유무에 대하여, 우리나라가 교과서 검정 제도를 채택하고 교육과학기술부의 심의 등을 거치도록 한 것은 헌법상의 교육의 자주 성, 전문성, 정치적 중립성을 구현하기 위한 것이다. 교육부장관의 수정명령이 교과서의 기술적 사항 또는 객관적 오류를 바로잡는 정도인 형식 요건을 넘어서서 내용적합성과 교육적합성까지 수정 대상으로 한다면 이는 새로운 검정절차를 밟는 것과 마찬가지로 교육과학기술부의 심의를 거쳐야 한다고 본다. 넷째, 수정요건을 법률로 명시하는 문제에 대하여, 교육부가 입법예고한 초·중등교 육법 개정 법률안에 따르면, 수정요건을 5개 항목으로 명시한 것은 장관의 임의적 재량 권에 제한을 가한 것으로 바람직해 보인다. 다만, 초·중등교육법 개정 법률안에 교육과 학기술부의 심의사항으로 수정에 대한 사항이 명시되어야 한다고 본다. This study explores the education minister`s authority of the textbook revision order, focusing on the Korean and Japanese history textbook lawsuits. The results are concluded as follows. First, regarding whether it violates the reservation of laws, the lower court acknowledges his comprehensive authority on the order of the revision. By contrast, the supreme court points out there are some restrictions on the relevance of education and contents despite approving of him asking to revise formal parts such as typographical errors. The court`s attitude toward the revision is changing like Japan`s fastidious authorization process. Secondly, with regard to the issue on plaintiff ship of the textbook writers, if his demand for the revision is applied only to the publishers, the writers perceive there is a high probability of their thoughts, philosophies, and academic perspectives in the contents could be distorted. Therefore, the writers have legal interests to require him to counterman his order directly. Third, as for whether or not to the deficiency in the screening process of the Textbook Screening Council runs counter to the law, adopting the textbook authorization system and the screening system is regarded as one way to guarantee independence, professionalism, and political impartiality of education under the law. Nevertheless, if he has the power to demand for the formal revision such as objective error correction but also even the direct authority over the relevance of education and the written contents, it may seem to go through the new screening process. Fourth, in terms of the matter of whether the revision requirements are prescribed by Act, it is desirable that the requirements consist the five items in the amendments of the Elementary and Secondary Education Act since his arbitrary discretionary authority must be subject to certain restrictions. However, the requirements of the revision should be specified in the amendments of the Act as the screening requirements.
