The ion exchange resins have been synthesized from chlormethyl styrene - 1,4 - divinylbenzene(DVB) with 1%, 2%, 4% and 8%-crosslinking and 1-aza-18-crown-6 macrocyclic ligand by copolymerization method. Content of chlorine in styrene-DVB copolymer was decreased as crosslink increased and it is because as crosslink increased 1%, 2%, 4% and 8% DVB content increased and crosslink density increased and cavity was reduced. Functional group of resin almost disappeared as C-C1 peak around $700cm^{-1}$ was substituted with 1-aza-18-C-6 macrocyclic ligand and new peak of C-N around $1020cm^{-1}$ appeared, so it was confirmed that styrene-DVB copolymer and ligand were compounded. As crosslink increased in the analysis of element contents, it resulted in the reduction of nitrogen content and it is because as crosslink increased, it led to the reduction of chlorine content in the process of substitution reaction and it affected macrocyclic ligand substituted. Thermo analysis curve of functional synthetic resin decomposed three part of 1-aza-18-C-6, styrene, and DVB. Form of functional synthetic resin showed distortion of its particles as macrocyclic ligand was introduced to styrene-DVB copolymer and hydrogen of ligand caused substitution with chlorine element of styrene molecule.

목적: 현장실습 내용의 적절성과 표준화된 실습내용을 개발하는 기초자료를 얻고자 하였다. 방법: 2009 년도부터 2011년도까지 현장실습을 이수한 전체 인원에 대하여 연도별, 성별, 지역별 실습 내용을 분석하였다. 결과: 평균 실습 일수는 24.27일 이었고 일일 평균 수행 일의 요소는 2.74개로 나타났다. 연도별, 지역별 실습내용의 변화를 볼 수 있었다. 남 여 학생의 실습내용도 일의 요소 수행에서 남학생의 경우 전체 일의 요소에 대한 빈도는 차이가 났다. 결론: 현장실습을 규격화할 수 있고 현장실습에서 요구하는 일의 요소가 포함되며 안경광학과 교육목표에 부합되도록 체계화된 실습매뉴얼의 개발이 필요하다.

We studied the meaning of the term avant-garde in relation to clothing of the 1980s and 1990s by examining the media's perceptions of Martin Margiela, a Belgian deconstructionist designer who was often labeled as avant-garde by journalists, scholars, and fashion critics in the late 20th century. A five-step content analysis method described by Paoletti (1982) was used to conduct the research. Newspaper and magazine articles in the 1980s and 1990s were analyzed using a set of existing avant-garde characteristics developed by Crane (1987) to determine if those journalists' perceptions matched the characteristics described by Crane. Results indicated that the journalists' critiques and descriptions matched the avant-garde characteristics described by Crane (1987). Including a subjective element to the conceptualization of the term explains how journalists described Margiela's designs despite Japanese designers' use of similar techniques before him. We (re) conceptualize the term's latter 20th century meaning and shifting dialogue to include a subjective element.

Developed the model equations which calculate roll force, roll power during hot rolling in real time. The variables which mainly effect on the roll force, roll power are shape factor, reduction, roll diameter, roll velocity, strip inlet temperature, carbon content of strip and strip-roll contact friction coefficient. Among these variables roll diameter, roll velocity, inlet temperature, carbon content and friction coefficient can be excluded in interpolated model equation by introducing equation of die force(F'), power(p') of the frictionless uniform plane strain compression which can be calculated without iteration. At the case of coulomb friction coefficient of 0.3, we evaluated coefficient of polynomial equations of {{{{ { F} over {F' } }}}}, {{{{ { Pf} over {Pd }, { Pd} over {P' } }}}} from the result of finite element analysis using interpolation. It was found that the change of values of {{{{ { F} over {F' }, { P} over {P' } }}}} with the friction coefficient tend to straight line which slope depend only on shape factor. With these properties, developed model equations could be extended to other values of coulomb friction coefficient. To verify developed roll force, roll power model equation we compared the results from these model equation with the results from these model equation with the results from finite element analysis in factory process condition.

The purpose of this study is to provide a meaningful thought to professionals and administrators of Korea working for Consumer General Education development at their Universities. Also, tips for organizing and meaning Consumer General Education Curriculum effectively are provided. Finally, the study suggests essential elements to improve qualities of Consumer General Education in Korea Universities. This study's method are content analysis through web site and survey. The subjects of this survey were 257 students. The data were collected by questionnaire developed by researcher and analyzed by frequencies, correlation Analysis, One Way Anova, Duncan Test, Factor Analysis, Multiple Regression Analysis. The major findings were as follows: University students's satisfaction level about General Education was low and the needs level about Consumer General Education was high. And the education service quality showed factors to be administrative service element, professor service element, classroom environment element, communication element. And Multiple Regression Analysis on each of the education service quality factors had been significant effects for find out the differences in the degree of satisfaction.

This study was intended to point out the limit of existing digital content-centered studies, or approaches from the viewpoint of the supplier and in the aspect of business profit model and find ways to assess the quality of digital content, considering the characteristics of digital content. For this, the study is to apply value innovation strategy to digital content assessment, to analyze the applicability, and to propose a new and practical framework for digital content assessment method. To this end, this study selected the global No. 1 search service provider Google and local portal site Naver search service. The study on assessment factors by value innovation strategy was based on existing literature, while user-value elements in that respect were confined to information quality, interactivity, communication, interactive storytelling, and usability. This study objectified the relation with the value innovation strategic analysis, through qualitative and quantitative analyses on value elements of search service users.
