This study aimed at examining how the organizational citizenship behavior as a significant attitude variable of organization members appear through daily sports activities and self-efficacy in local administration organization. First, is there a difference in daily sports activities, self-efficacy and organizational citizenship behaviors depending on socio-statistical characteristics of organization members? Second, is there any difference in self-efficacy and organizational citizenship behaviors depending on whether organization members participate in daily sports activities of rough organization members or not? Third, does the degree of participation in daily sports activities of the members have an influence on self-efficacy? Fourth, does self-efficacy of the members have an influence on organizational citizenship behaviors? Fifth, does the degree of participation in daily sports activities of the members have an influence on organizational citizenship behaviors? Finally, how much will the degree of participation in daily sports activities of the members have an influence on organizational citizenship behaviors thself-efficacy?

Saccharin의 展望性있는 化學的 製法과 副産物의 利用에 關한 硏究

柳珙植 群山大學校 1983 論文集 Vol.6 No.-

It seems very likely that the consumption of saccharin will be increased, according to the increasing national income and the variety of processed foodstuffs, with demand of carolieless foodstuffs for the prevention of supernutrition and diseases of adult people. Therefore all the nations in the world have been concentrated on developing artificial sweetstuffs substituting sugar for. As a result of it, the manufacturing process in the past was the one which used to solve O-toluene Sulfon Amid with 30% Sodium Hydroxide; this time the method is the one which is solved with definite diluted Sodium Hydroxide. This is why we want to reduce the poionous content as possible avoiding conc Alkaline Substances. Para-toluen Sulfo Chloride produced as by-product seems likely to be used as the followings: (1) the Ester, treated and manufactured with Alkaline Alchol, can be used as Alkalifing Reagent. (2) This Chloride can be used as Chlorifying Agent of Carbon Acid in Organic Synthesis. (3) this Chloride is used for the manufacture of Dialky1 Amine. (4) this Chloride is used for the manufacture of Chiramine T, Water disinfectant and Halazone. As the above, in order to keep our good health and to save foreign currency, we should not import the whole quantity of original crude sugar, but develop this area, by-products produced in the manufacture, and poisonless Saccharin in large quantity. Thus, if we export this in large quantity, taking the exclusive property of each market in the world, it is expected that this would contribute to economic development for exporting Korea.

絹/毛混紡織物의 一浴染色法에 관한 硏究

金公朱,姜濚義 全北大學校 1988 論文集 Vol.30 No.-

Silk and wool are the two most important natural protein fibers. Because of there different Physical chemical properties the two fibers show quite different dyeability. In this study, we tride silk/wool blend fabric in one step using a one bath dyeing method. Acid dyes, 1 : 2 type metal complex dyes, and complex type reactive dyes used as the dyes. The results of the exsperiments can be summarized as follows

폴리 에틸렌 테레프탈레이트 섬유의 改質에 의한 染色性 改良에 關한 硏究

金公朱,姜濚義 全北大學校 1979 論文集 Vol.21 No.-

This paper concerns with the utilization of the treatment of sulfuric acid for improvement of dyeing of poly ethylene terephthalate(P. E. T) fiber. The P. E. T. fiber drafted to various times was treated with 70~74% sulfuric acid at 80~95℃ for 30~120min and neutralized with 2% ammonia. The fiber thus prepared has remarkable advantage in high yields of colours when dyed with C. I. Basic Green 4. The tensile strength of 3.2 times drafted P. E. T. fiber is as high as that of used fiber.

견/합성섬유 혼방품의 1욕염색(Ⅶ) : 견/아크릴로니트릴 섬유 혼방품의 염색거동 Adsorption Behavior of Silk/Acrylonitrile Fiber

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.

In order to investigate the statistical analysis of ambient suspended particle at Seoul in Korea, airborne particulate matters were collected by High-Volume Air Sampler from April 1988 to May 1991, and size distribution of the aerosols were measured by filters on nine stages Andersen Air Sampler from January 1990 to December 1990. And with respect to seven components in the total suspended particulate, the factor analysis was performed. As a result of factor analysis by using the varimax rotation method, the chemical components in the TSP were able to characterize with two principal factors. The first factor (Factor 1) was considered to be a factor indicating the contribution of natural sources and the second factor(Factor 2) was a factor indicating the contribution of anthrophogenic sources. For concentration of size distribution measured by Andersen Air Sampler, tne factor analysis was also performed. As a result of factor analysis by using the varirnax rotation method, particle size distribution of atmospheric particulate was divided into two groups, coarse particle group was made by particles lager than 2.1㎛ in diameter and fine groups smaller than 1.1㎛ in diameter.

학습자의 평가 참여를 지원하는 웹 기반 수행평가 시스템의 설계 및 구현

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.

I have investigated from surfactant to be used widely in daily life. 1. I have found a lot of special interesting things in which consists of Hydrophiles solution and oil. 2. I have reaffirmed to find out two kinds of type of dissociation which is done and not. It would be necessary to be capable of searching for the development of use in ion. 3. I have found the result in which surfactant could be applied in every field of utilities. Above all, emulsification has been functioned with a big important utilities. Above all, only the best way to choose suitable surface tention must be understood its function and utilities of it.
