본 연구에서는 호소수의 정수처리공정 중 폴리술폰계 중공사막을 이용한 침지형(흡인압)과 외압형을 동시에 적용한 분리막 공정으로 압력 및 공경에 따른 투과플럭스의 변화에 관한 성능을 평가하고자 하였다. 침지형(흡인압) 공정의 압력에 따른 최대 투과 플럭스는 공경이 0.3 μm에서 평균 282 LMH, 0.05 μm에서는 234 LMH를 나타내었으며 외압형(외압) 공정의 압력에 따른 최대 투과 플럭스는 공경이 0.3 μm에서 평균 443 LMH, 0.05 μm에서는 522 LMH를 나타내었다. 또한, 흡인압과 외압을 동시에 적용한 공정의 압력에 따른 최대 투과 플럭스는 공경이 0.3 μm에서 평균 674 LMH 0.05 μm에서는 648 LMH를 나타내었다. 따라서, 호소수를 이용한 정수처리공정에서 분리막으로 흡인압과 외압을 동시에 이용할 경우 단위 면적당 생산수를 최대로 할 수 있을 것으로 사료된다.

In spite of importance of safety issues in community sport, little concerns have been paid to the sport safety policy. Governing bodies and individuals involved with the facility management have a responsibility to manage the risks at acceptable levels. For sports injury prevention interventions, the safety policy of sport facilities should be made to provide a structured framework which can be implemented at community sport. Hence, the current study is to identify the safety issues and to generate the policies that assist to conduct the systematic safety management at sports facilities. For this, the current study analyzed two cases from Japan and Germany. The study reviewed multiple pieces of literature including journal publications, political reports, and media coverage. Through review, the study analyzed the organizational structure, legal systems, and political stance of the safety management of sport facilities in Japan and Germany. The results proposed the following issues. First, law needs to be enacted to establish the control tower where has a responsibility to develop the safety manual and system. Second, local organizations need to be established to educate individuals working in sport facilities and inspect the facilities. Further political issues were discussed for safety management in Korea sport facilities.
