폴리우레탄 섬유의 染色機構에 關한 硏究

金公朱,朴炳基,姜濚義 全北大學校 1980 論文集 Vol.22 No.-

Spandex is man-made elastomer fiber. Chemically, polyurethane is produced by interaction of Glycol and Diisocyanate. From a physical point of view, these Spandex fibers owe their elasticity to the same thermodynamics as rubber, therefore, the high degree of fabric stretch availability permits its use in a wide range of textile fabrics. Particular interests are to improve the dyeing properties and to find out the dyeing mechanism. So, it is the purpose of this paper to present technology which will permit these yarn to be dyed with selected dyes and to describe the dyeing mechanism.

漱石作品における文體の變遷について : 「如し」を例として

羅工洙 全南大學校 人文科學硏究所 2001 용봉인문논총 Vol.30 No.-

근대 일본 소설의 거장인 나쓰메 소세키(夏目漱石)의 작품을 통해서 그 문체의 변화를 고찰하였다. 지금까지의 연구와는 다른 방법으로 「如し」를 통해서 고찰하였다. 그 내용을 정리하면 다음과 같다. ① 「如し」 와 「 樣だ」 의 사용률을 볼 경우, 초기작품에 비교적「如し」 의 비율이 높고, 후기작품으로 갈수록 점점 줄어든다. ② 「如し」의 활용을 볼 경우, 초기작품에 훈독문에서 많이 사용되는 종지형이 보이지만 후기 작품에는 사용되고 있지 않다. 그리고 동사 연용형과 접속할 경우, 훈독문에서 많이 사용되는 격조사 「が」 가 초기작품에 많이 있지만, 후기작품에는 사용되지 않는다. ③ 「みたやうだ」「みたいだ」를 볼 경우, 전 작품에서 「みたやうだ」가 보이지만, 후기작품에서 신 어법인「みたいだ」가 사용되고 있다. 이러한 결과가 나온 배경은 소세키는 어릴 적부터 한문을 배웠고, 기본적으로 한문의 소양이 깊었기 때문이다. 많은 한시를 남긴 것으로도 그 능력이 있음을 알 수 있다. 소세키는 작가활동을 타인보다 늦게 시작하여, 이미 언문일치의 확립.성립의 시기에 출발하였고 작가자신도 언문일치에 지대한 관심을 갖고 있었다. 그러나, 한문에 소양이 깊었던 소세키는 언문일치의 문장에 한문맥과 같은 문어적 표현을 써 넣고 있다. 그것이 특히 초기문장에 그 빈도가 높고, 후기작품에 갈수록 작아지는 것이다. 짧은 작가생활이었지만, 점점 구어화 할려고하는 움직임이 있었다.

대기중 부유입자상물질의 통계적 해석에 관한 연구

강공언,신대윤 조선대학교 생산기술연구소 1992 生産技術硏究 Vol.14 No.2

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.

Recreation과 체육에 관한 연구

尹恭和,吳柱勳 慶一大學校 1999 論文集 Vol.16 No.4

The results of this study on recreation and physical education are as follows : 1. It is necessary to develop technique and to cultivate taste of sports and plsy which can enjoy recreation as physical training. 2. It is necessary to make use of spare time and to build up view of value which rightful understanding and attitude on recreation. 3. It is necessary to create atmosphere in other that one may always apply recreation by completely furnishing physical facilities. 4. It is necessary to improve practical habit and capability which can assist physical training by making spare time fitting to aptitude. 5. It is necessary to emphasize importance of role in physical training as rightful recognition on recreation.

금강 하류의 기초생산성에 관한 연구 : 最長漲潮期(夏8~9月)의 염소도, 수온.PH, 영양염류 변동에 관한 연구 Study on the changes of chloronity, PH, water temperature, nutrient salts during the month at the greatest tidal cycle

유공식 군산교육대학 1971 論文集 Vol.4 No.-

In order to study about the basic productivities on the estuary of the Kum River, first, I conducted several experiments on the tidal variation on the site encircled on Fig. 1. I measured PH, water temperature, outside temper ature, chloronity, nutrient salts. PH variation range was 7. 20-7. 95, water tempreature increased with outside one, chloronity varied from 1.0 to 13‰, NO2-N increase is proportional to part of fresh water flowed into the estuary and their range is 0.28-0.15㎍-aton/L. P04-P content increase is reversely proportional to fresh water content In general nutrient salts showed more higher value with water temperature increase. The results in detail of this experiment are shown up at Table 1, 2.

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.

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.
