Purpose: Through studying the expert`s and non-experts panel responses to the questions regarding the attributes of chemical-biological protection cloth quality in terms of the levels of customer demand and technical factors has been studied. We are applied to a QFD matrix with find out the relationship between the selective removal efficiency of chemical-biological cloth and the guidelines of technical approach. Methods: We fabricated several composite of ion-exchange resins with selectively permeable performance designed to facilities water vapor transport and selective adsorption of the harmful gases. With these materials, we characterized on the selectively permeable performance to identify ion-exchange resin with chemicalbiological protective cloth. Results: Results showed that ion exchange materials possessed performance with selectively efficiencies as NH3, SOx, NOx and HCl gas. The selective adsorption amount of ammonia and hydrogen gases were 90-80 ㎍/g with TRILITE SCR-BH sulfonated ion exchange resin. The PP non-woven/ion exchange resin adsorbent materials possessed performance with water vapor permeability were 1,100-1,350 g/m2/day, it`s was two times high value compare with activated carbon. With these materials, we characterized selectively removal efficiency to identify new ion-exchange material with chemical-biological protective capability. Conclusion: This study shows that a QFD aids in deciding with of the adsorption parameters to optimized with chemical-biological protection cloth manufacturing.

본 연구에서는 인터넷 교육방송이 교수매체로서 학습자들에게 얼마나 만족하게 평가되고 있는지를 파악함으로써, 인터넷 교육방송 강좌 개발과 운영의 질적 향상을 위한 기초자료를 제공하고자 한다. 본 연구의 목적을 달성하기 위하여 다루어질 구체적인 연구 문제는 다음과 같다. 인터넷 기반 교육방송 강좌에 대한 학습자의 만족도는 어떠한가? 본 연구의 결과로 인터넷 교육방송 강좌 8개 영역 대부분이 학습자의 만족도가 평균 이상이 된다. 인터넷 교육방송 강좌에 관하여 학습자를 대상으로 수업 지원환경, 인터넷 기반 교육방송 수업 태도, 교수설계전략, 학습내용 제시 전략, 화면 디자인 및 인터페이스 전략, 학습지원 기능, 운영자 및 사이버 조교지원, 인터넷 교육방송 강좌에 관한 종합 평가 등 8개 영역으로 구성하여 인터넷 교육방송 강좌 영역별 만족도 차이를 파악하였다. 인터넷 교육방송 강좌에 관한 영역별 요소는 학습자의 만족도 요소를 파악하게 함으로써 인터넷 교육방송 강좌가 학습매체로서, 일종의 학습과정으로서 평가받게 되는 결과를 기대한다. The cutting-edge information engineering is getting human beings together and leads to formation of human network through the combination of multimedia and internet. The 21st century advances in technology realizes desire for human knowledge changing from demand-side educations to supply-side educations. One of the most innovative masterpiece by internet is internet broadcasting. Bill Gates said its appearance is much more of an epoch-making event than the discovery of computer. With the limits in one-way communications and synchronous environments overcome, the multi-channelled, multi-programmed learner-centered approach is made available. Internet broadcasting as a new paradigm for educational technology is on the horizon. This study evaluated the overall satisfaction with internet educational broadcasting courses, interview with the instructors in charge. The following issue was researched for this thesis: What is the satisfaction degree of learners with the courses? Data from semantic differential scales, and Likert-type items was analyzed according to the eight areas. With the results that the learner was satisfied with internet educational broadcasting, could we expect its activation. Comparing dimensional results from the questionnaire on the 5-point scale, the section for the overall assessment from the learner was much higher than any others at 4.11 and the lowest "support service environment" was shown above average at 3.42. We could capture the satisfaction elements per area, which help pave the way to a learning media, furthermore to a learning progress. High satisfaction degree of learning support function, screen design, and interface strategy made an overall average relatively high. Based on the research above, several findings can be discussed. First of all, it is important to investigate and discuss an authentication in all learner's aspects. It is consider learner's telecommunication engineering environments. It is important to design a good screen for the students, too. Next, it is essential to provide an output of continued courseware development research of multimedia effect for internet educational broadcasting. Finally, it is need to provide an interaction, feedback, and continued management in internet educational broadcasting course to effectiveness of class. The followings are further research knowledge. There is a strong need to research in the development of an instructional design model and strategy. It is essential to research in a need analysis of learner, too.
