Emulsion型 液體膜에 의한 Toluene과 n-Heptane 混合物의 分離
金周德,鄭泰秀 成均館大學校 科學技術硏究所 1989 論文集 Vol.40 No.1
In the separation of toluene-n-heptane mixture by emulsion-type liquid membrane, studied were the effects of the following factors on the separation factor: surfactant concentration, stirring speed in emulsification, glycerol concentration and volume ratio of solvent to feed. The separation factor of toluene reached a maximum value at the surfactant concentration of 0.6 weight percent and contact time of 10 minutes. The separation factor increased with increasing stirring speed in emulsification, giving the greatest value at the contact time of 10 minutes. The separation factor of toluene reached a maximum value at the glycerol concentration of 0.6 weight percent and contact time of 10 minutes. The separation factor increased with increasing stirring speed in emulsification, giving the greatest value at the contact time of 10 minutes. The separation factor of toluene reached a maximum Value at the glycerol concentration of 30 weight percent. When the volume ratio of solvent to feed is equal to three, the permeation of toluene reached a maximum value.

본 연구는 델파이 조사를 통한 전문가 협의과정을 거쳐 지도자들이 필요한 지식 및 역량을 정립하여 장애인 재활운동 및 체육 지도자 양성을 위한 교육과정 개발의 전반적 방향을 모색하기 위한 목적으로 수행되었다. 장애인 재활운동 및 체육 관련 이해관계자 80명을 전문가 패널 범주에 포함시켰으며, 전문가의 의견을 수렴하는 방법인 델파이 조사를 총 2회에 걸쳐 실시하였다. 델파이 질문지는 장애인 재활운동 및 체육 지도자에게 필요한 지식 및 역량에 대한 내용으로 구성되었고 연구결과는 다음과 같다. 장애인 재활운동 및 체육 지도자 교육 과정 범주화를 위해 총 8가지 세부영역(체육 전반에 관한 지식, 인체의 해부학적 지식, 장애의 유형별 특성에 관한 지식, 운동 기능의 평가와 처방에 관한 지식, 운동지도에 관한 실무 지식 및 역량, 안전과 부상예방 및 대처에 관한 지식, 장애인 및 의료관계 법령에 관한 지식, 장애와 복지 관련 지식)으로 구성하여 교육과정을 최종 범주화하였다. This study was conducted to find the overall direction of the development of curriculum for the training of rehabilitation sports instructors for the disabled by establishing the knowledge and competence required by the instructors through the expert consultation process through the Delphi survey. 80 stakeholders related to rehabilitation sports for the disabled were included in the expert panel category, and Delphi survey, which is a method to collect opinions of experts, was conducted twice in total. The Delphi questionnaire was composed of the contents about the knowledge and competence required for the rehabilitation exercise instructor for the disabled. The results of the study are as follows. For the categorization of courses for rehabilitation sports instructors with disabilities, the curriculum was finally categorized into eight detailed areas(Knowledge of Kinesiology in general, Knowledge of the Human Anatomy, Knowledge of the characteristics of each type of disability, Knowledge of evaluation and prescription of exercise functions, Knowledge of practical affairs and competence about exercise instruction, Knowledge of safety and injury prevention and response, Knowledge of disability and medical legislation, Knowledge of disability and welfare).
