金公朱,김경수,전재홍,이화선 全北大學校 1995 論文集 Vol.40 No.-

In one bath dyeing system of silk/acrylonitrile(acryl) fabric with acid/disperse dyes and acid/cation dyes, adsorption behavior of acid dyes, disperse dyes and cation dyes on silk and acryl fabrics were examined. In the dyeing of acryl with the C. I. Disperse Red 19(Red 19) and The C. I. Disperse Red 60(Red 60), dye uptake with Red 19 was higher than that with Red 60. When the silk and acryl fabric were dyed with C. I. Basic Red 27(Red 27), dye uptake on the acryl was higher than that on the silk. When the silk/acryl fabric was dyed with Red 19 and Basic 27, solid shade could be obtained with Red 19 but could not be obtained with Basic 27. In the dyeing of silk/acryl fabric dyed with Blue 80/Red 27 and C. I. Acid Blue 113(Blue 113)/C. I. Basic Blue 116(Blue 116), compatibility could be obtained with Blue 80/Red 27 but that could not be obtained with Blue 113/Blue 116.

柳珙植 군산대학교 1980 論文集 Vol.1 No.-

As stated above, we can realize that 'Lime stone' is one of the most important resources which are able to hare a dirrect connection with organic and inorganic chemical industry. 'Lime stone' is gengraphically distributed on a large scale and its deposits arc not only inexhaust ible but also rather superior ill its quality. Therefore this Lime stone Industry is considered to involve the possibility enough to he developed, and the industrialization of 'Lime stonc' call be one of new ways out of difficulty in chemical industry field in Korea, none-oil producing country, suffering with scarcity of resources in general. The materials of chemical industry being 'Lime stone', how to develop and bring up our chemical industry --- that relys on how to produce abundant electric power in low cost. Saying again, the basic problem is that electric power producing in low cost is the only way to bring lip our chemical industry. Therefore if it is possible to produce electric power abundantly in low cost by developing all the rivers possible and build up water power plants it is believed that we are able to bring up this 'Lime stone' industry with it and produce the same products from 'Lime stone' as we get from the petrolium chemical Industry.

金公朱,박미라,강영의,김애순 全北大學校 1994 論文集 Vol.38 No.-

In one bath dyeing system of silk/cellulose triacetate(triactate) fiber blend fabric with acid/disperse dyes, adsorption behvior of acid dyes and disperse dyes on silk and triactate fabrics were examined. In the dyeing of triactate with the C.I. Disperse Red 19(Red 19) and the C.I. Disperse Red 60(Red 60) at 100℃, dye uptake with the Red 19 was higher than that with the Red 60. When the silk/triaceetate was dyed with Red 19 and the Red 60 at 100℃, dye uptake on triacetate was influenced by affinity of the dye to the silk fabric dyed together. In the treatment of the silk fabric dyed with the Red 19 and Red 60 in desorption bath with and without undyed triacetate, desorption of the dyes from the silk fabric was influenced by the affinity of the dyes to the triacetate. When the silk/triacetate was dyed with the Blue 80/Red 19 and Red 60 at 100℃, color of triacetate dyed with the Red 19 and Red 60 was not influenced by the Blue 80 but silk dyed with the Blue 80 was influenced by the Red 19.

익산지역에서 자동 및 수동채취방식에 따른 강수의 화학적 특성 비교

강공언 한국대기환경학회 2004 한국대기환경학회지 Vol.20 No.3

In order to understand the precipitation acidity and chemical composition of ion species in Iksan area as well as to know the difference of chemical characteristics in precipitation samples from the viewpoint of precipitation sampling method, precipitation samples were collected by wet-only automatic precipitation sampler and hulk manual precipitation sampler in Iksan, from March 2003 to August 2003. The mean pH of precipitation was 5.0. There was a little significant difference in the mean value of pH between automatic and manual sampler. However, pH values of some precipitation samples were lower in automatic sampler than in manual sampler, especially in case of precipitation samples with small rainfall for March 2003. The mean concentrations of each ions in precipitation were generally a little higher in precipitation samples collected by the manual sampler than in those collected by the automatic sampler because of accumulation of dry deposition on the surface of glass funnel installed at the manual sampler during the sampling period of no rainfall. Dominant species determining the acidity of precipitation, were NH₄+ and nss-Ca^(2+) for cations and nss-SO₄^(2-) and NO₃- for anions. The mean concentration of NH₄+ and nss-Ca^(2+)j were 31 μeq/L and 9 μeq/L for the automatic sampler and 40 μeq/L and 16 μeq/L for the manual sampler, respectively. In addition, nss-SO₄^(2-) and NO₃- were 27 μeq/L and 13 μeq/L for the automatic sampler and 32 μeq/L and 17 μeq/L for the manual sampler, respectively. Although the concentrations of the acidifying ions of nss-SO₄^(2-) and NO₃- were about 3 times higher than those for foreign pristine sites, precipitation acidity were estimated to be natural due to the neutralization reaction of the alkaline species of NH₄+ and nss-Ca^(2+) with its higher concentrations. Considering the ratios of nss-SO₄^(2-)/NO₃- and NH₄+/nss-SO₄^(2-), it was found that ammonium sulphate was dominant in Iksan precipitation. The major non-sea salt ions were maximum concentrations for March, but decreased with increasing of precipitation amount.

강공미,김진호 한국컴퓨터교육학회 2003 컴퓨터교육학회 논문지 Vol.6 No.3

수행평가는 학생들의 학습 과정을 관찰하거나 학생들이 산출해 낸 자료를 통해 평가하는 방식으로 단순 필답 고사의 단점을 보완하는 새로운 평가 방식으로 주목받고 있다. 그러나 이 수행평가를 적용하는데 많은 노력과 시간 부담이 들어 실제 학교 현장에서 시행에 많은 어려움을 겪고 있다. 이러한 부담을 줄이기 위해 인터넷을 이용한 평가가 다방면에서 시도되고 있으나, 이들 기존 연구에서는 학생의 평가 참여가 허용되지 못하며 평가 방법이 다양하지 못하거나 교사의 피드백이 부분적으로만 사용되는 문제점을 가지고 있다. 따라서 본 논문에서는 학습자들의 평가 참여 및 학습 과정 중의 다양한 수행평가를 지원하고 교사가 효과적으로 관리할 수 있는 웹 기반의 수행평가 시스템을 설계하고 구현하였다. 이러한 웹 기반 수행평가 시스템을 활용할 경우, 학생들의 평가력 등의 고등사고 능력과 전인적 발달을 도모하고, 수행평가를 위한 교사의 업무와 시간 부담을 대폭 줄일수 있을 것이다. A performance evaluation, which requires to observe students in the course of teaming and studying and to evaluate their reports and materials, is emerging as an alternative evaluation method to overcome the shortcoming of simple written tests. However, there are many difficulties in real teaching setting to apply the performance evaluation, because it requires many burdens of efforts and time. In order to reduce these burdens of teachers, there have been several approaches which utilize the Internet for the evaluation. But these previous approaches have several limitations that they don’t allow students’ participation in evaluation activities, fail to provide a variety of evaluation methods, and/or support teachers’ feedbacks very limitedly. In order to overcome these limitations, therefore, this paper designed and implemented a web-based performance evaluation system supporting the participation of students in doing evaluation themselves and various evaluation methods, which can be effectively managed by teachers. This web-based performance evaluation system developed in this paper can enhance not only students’ high level thinking abilities but also their emotional and intellectual abilities. It can also help teachers to reduce the burden of working and the time in plenty used for evaluating students.
