돌로마이트 폐기물 슬러지에 Al(OH)₃와 SiO₂를 첨가하여 코디어라이트와 규회석을 합성하고자 하였으나 1250℃소성으로 코디어라이트는 MAS조성에서 합성되지 않았으며 규회석은 합성이 되었다. 돌로마이트 내화물의 내수화성을 증가시키기 위해 슬러지에 Fe₂O₃를 6%이상 첨가하여 소성한 결과 입계에 (Ca·Mg·Al·Fe)SiO₂의 생성으로 인하여 내수화성이 증가되었다. The possibility of synthesis for the cordierite and wollastonite with dolomite waste sludge, Al(OH)₃ and SiO₂ was studied. With the composition of MAS, the cordierite was not synthesized at sintering of 1250℃ and the wollastonite was made at the same temperature. The addition of Fe₂O₃ above 6% to the dolomite for the antislaking behavior has promoted the sinterability of dolomite and (Ca·Mg·Al·Fe)SiO₂ at grain boundary was affecting the increase of antislaking.

철원산 현무암에 Al₂O₃와 CaO를 각각 첨가하여 결정화유리를 제조하고 그 물리적 특성을 조사하였다. SiO₂8.3wt%, CaO 20wt% 그리고 Al₂O₃8.3wt%를 현무암에 첨가하여 단일상의 Diopside 와 Anorthite를 제조할 수 있었으며, CaO를 첨가한 경우에는 첨가된 CaO가 결정핵으로 작용하여 anorthite와 diopside의 혼합 결정상이 얻어졌으며, Anothite는 CaO 첨가량이 증가함에 따라서 감소하는 경향을 나타내었다. Al₂O₃를 현무암에 첨가하면 hercynite(FeO·Al₂O₃)의 분해에 의해 anorthite가 생성되고 있음을 알 수 있었다. CaO 20wt% 첨가한 경우 900℃에서 2.93g/㎤의 부피 비중과 215MPa의 곡강도를 Al₂O₃ 8.3wt% 첨가한 경우에는 1000℃에서 2.83g/㎤과 210MPa의 곡강도를 나타내었다. 흡수율은 Al₂O₃8.3wt%, CaO 15wt% 그리고 Cao 20wt% 첨가한 경우 모두 900℃ 이상에서 1% 이하의 낮은 흡수율을 나타내었으며, 열팽창계수는 Diopside의 peak intensity가 증가함에 따라 증가하였다. Glass-ceramics were prepared by adding CaO 8.3wt%, 15wt%, 25wt% and Al₂O₃8.3wt% to SiO₂ 8.3wt% added Chulwon basalt and their effects of phase transition and firing temperature on the densification, microstructure development and thermal expansion coefficient were investigated by means of XRF. SEM and diletometer. It was one phase of diopside and anorthite respectively. The CaO added to Chulwon basalt played an role of crystal site of anorthite and diopside. However anorthite decreased and finally disappeared according as CaO addition increased by 20wt%. In case of decomposition. The flexural strength of CaO 20wt% added glass-ceramics fired at 900℃ and Al₂O₃ 8.3wt% added glass-ceramics fired at 1000℃ was 215MPa and 210MPa respectively. The thermal expansion coefficient varied from 6.554×??/℃ to 8.146×??/℃ depending on diopside peak intensity of CaO added glass-ceramics on XRD results.
企業會計基準의 改正에 따른 法人課稅所得計算 關聯規定의 改善方案

우리 나라 기업회계기준이 1981년에 제정된 이래 6차의 개정을 거쳤으나 지금까지의 개정은 주로 국내적 환경변화에 따라 이루어진 것인데 비하여 1996년 3월 30일자의 대폭적인 개정작없은 국제적환경변화에 부응하기 위한 것이었다는 것에서 그 특징을 찾을 수 있다. 이번의(1996. 3. 30) 개정은 세계무역기구(WTO)체제의 출범과 우리 나라가 경제협력개발기구(OECD)에 가입하므로 국내기업의 해외시장 이용이 점차 활발해지는 환경변화에 대처하기 위하여 이루어진 것이라고 보아야 할 것이다. 이번 개정의 기본방향은 국내기업 재무제표의 국제적 신뢰도와 이해가능성의 제고, 국제간 비교가능성의 확보를 위한 국제회계기준의 적극수용, 규제중심의 기준에 유연성을 부여하고, 회계기준의 합리성과 논리성의 확보, 계정과목 단순화를 통한 이해 가능성의 제고이다. 본 논문은 이상과 같은 기업회계기준의 개정방향에 따라 개정된 내용을 검토하고 이와 관련된 법인과세소득계산과 관련된 법인세법의 개정방향을 논의하였다.
유전체 배리어 방전 플라즈마를 이용한 애시드레드 27 수용액의 색도 제거

The physicochemical processes of dielectric barrier discharge (DBD) such as in-situ formation of chemically active species and emission of UV light were utilized for the decolorization of an aqueous solution formed with distilled water and an azo dye Acid Red 27. The DBD reactor consisted of two coaxial dielectric tubes with different diameters. Aqueous electrolyte solution was filled in the inner tube, which acted as the discharging electrode. The DBD reactor was submerged in the Acid Red 27 solution that was grounded. In this case, the Acid Red 27 solution acted not only as the counter electrode but also as the cooling medium of the DBD reactor. The DBD reactor with the aqueous discharging electrode was found to be more energy-efficient for the generation of ozone than that with typical metal electrode. The chemically active species (mostly ozone) produced in the DBD reactor were well dispersed in the Acid Red 27 solution using a porous gas diffuser, thereby increasing the gas-liquid contact area available for the decolorization. The results have clearly shown that the DBD reactor system was very effective for decolorizing the Acid Red 27 solution. For the purpose of improving the performance of the DBD reactor system, MnO_(2) catalyst was added to the Acid Red 27 solution. It was found that the catalyst significantly enhanced the decolorization.
Influence of Squid Liver Powder on Accumulation of Cadmium in Serum, Kidney and Liver of Mice

In this study, the effect of squid liver powder intake on accumulation of cadmium in mice was investigated. Subjects were divided into 4 groups including the control group (CON), squid liver powder group with lipids not removed (SLP100), and squid liver powder groups with lipids removed (LFSLP50 and LFSLP100). Feed intake and food efficiency ratio of squid liver powder groups was significantly higher than the CON. As a result of investigating cadmium content in hair, serum, liver, and kidney during intake of squid liver powder, all groups showed increase in cadmium accumulation through consistent, long-term intake. Especially, cadmium content in liver and kidney of LFSLP100 was significantly higher than the content of SLP100 and CON. As a result of pathological observation on liver and kidney tissues according to squid liver powder diet, LFSLP100 showed most serious pathological symptoms. In case of kidney tissues, degeneration was significantly more severe in LFSLP100 compared to other groups. Such results suggest that cadmium concentration in human body can be increased by ingestion of whole squid including internal organs and that tissues can be damaged by increased cadmium concentration. More specific and systematic studies are deemed necessary.
