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.

The subjects of this study were sampled by using the Cluster Random Sampling with the population that consists of the 4th, 5th and 6th graders of elementary school and the 1st, 2nd and 3rd graders of middle school, who are currently training at Taekwondo training centers in Metropolitan City. The way to sample was made by randomly sampling 500 men and women from 30 Taekwondo training centers, which are registered at the Taekwondo Association of Kwangju Metropolitan City, and having a questionnaire survey with the method of self-assessment marking, that is, the direct interview method. Except 58 questionnaires that were judged to answer insincerely or had missing parts, 422 questionnaires were used for the actual analysis. The objective of this study is to research the trainees' satisfaction level about facility factors, analyze the contents, and thereby make the plan to activate Tae kwondo training centers, in order to effectively operate Taekwondo training centers. Thus, this study concluded as follows. First, it showed no significant in the comparison by gender and training period, and it showed the significant difference between 4th and 5th grader trainees of elementary school ~1st grader trainees of middle school and over 2nd grader trainees of middle school. Second, the satisfaction level of 4th grader ~1st grander trainees of middle school for facility factor was shown as high, whereas over the 2nd grader trainees of middle school low. Third, as for age, it showed the significant difference between the 10 year -old trainees, 11 year-old trainees ~14 year-old trainees and over 15 year-old trainees, and the satisfaction level of 10 year-old trainees for facility factors was shown as high, wheres over 15 year-old trainees low. Fourth, as for grade(Poom Geup), it showed the significant difference between the trainees with Geup grade and trainees with over Poom grade, and it showed the characteristic that the satisfaction level of the trainees with Geup grade for facility factors was high, whereas the trainees with over Poom grade low.

This study was undertaken in an attempt to explore nursing student health behaviors. Based on responses from 218 2nd grade nursing students in nursing college in the City of Incheon health behaviors were evaluated. Data were collected from 19th of August to 5th of September in 1998. The open ended questionnaire which was used in study formulated based on literature review and contained health concept, personal habits, exercise, cause of the stress and stress management. The results of the analysis were as follows ; 1. The nursing student thought health as an adaptation mostly. 2. 1.8% of the student smoked the cigarettes. 3. 78.0% of the student drinked the alcohol. Most of them began to drink by peer pressure. 4. 97.2% of the student consumed caffeine-containing products. But most of them don't consumed much. 5. 36.7% of the student took the drugs. Most of the drugs were analgesics & vitamins. 6. 39.4% of the student exercised regularly. Most of the type of the exercise were physical exercise and walking. 7. Most of the causes of the stress were the burden of the school works. Most of the stress management were sleeping.

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.

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.

This study was conducted to determine the inertial charactristics of the body segment such as mass, mass center, and moments of inertia with respect to the three principal axes of rotation passing through the mass center of Korean male gymnasts using a mathematical model. The subjects chosen for this study were 7 male university gymnasts of 18-21 years of age. Two 35mm cameras enabled simultaneous photographs of the body to be made. The optical axes of the cameras were horizontally aligned to provide anterior and lateral views of the body. The photographic records were analyzed by reading the image using the scanner, defining the contours and required points of the segments using the mouse, and computing the inertial charactristics. The model of the human body described in this study was an advancement over previous mathematical models in that a representation of the segments by elliptical disc 5 mm wide followed the shape fluctuation of the body more closely. The accuracy of the method was evaluated by comparing the estimates of total body mass with the mass as measured on weigh scale. Table 2 provides the results of this study as mass, mass center, and moments of inertia of male gymnast body segment.
