N/A The efficacy of a highly purified, formalin inactivated hepatitis B vaccine (Hepavax-B®), 20ug of surface antigen (HBsAg), given at 0, 1, and 6 months, was evaluated in 83 healthy young volunteers (mean age;25 years old) according to the injection sites of vaccine. All three doses had been given by arm injections in 51 subjects (A group) and the remainders (22 subjects) had received buttock injections for the first 2 doses followed by third-dose arm injections (B group). A significant decrease in seroconversion was noted 6 months after first dose injections in B group male subjects (31%) comparing with B group females and A group males and females, but conversion rate was rapidly elevated (95%) shortly after third-dose arm injections in these subjects. Geometrical mean antibody levels expressed as ratio units (RU) were significantly low 6 months after first dose injections in B group (both female % male) (p<0.005 vs. A group). This difference between A & B group was disappeared by the rapid increase of antibody level in B group subjects 2 months after third-dose injections, but in comparison with females, mean antibody level of male subjects was still significantly low in B group (p<0.005). Overall antibody conversion rates were over 95%, and antibody levels were above 10 RU in 90% of responders in both A & B groups 2 months after third-dose injections. Subjects with antibody levels above 100 RU were 65% in A group responders at the same time. In conclusion, as a method of hepatitis B vaccination, arm seems to be a superior site of injection to buttock even in young persons whose expected antibody responses are known to be excellent.

본 연구에서는 국토교통부 건설기술연구사업을 통해 친환경 건설 비산먼지 저감제를 개발하였다. 기존 비산먼지 저감제들의 구성 성분 분석 및 성능 확인, 하이브리드 폴리머계 수지 비산먼지 저감제 개발, 생분해수지 기반 비산먼지 저감제로 Build-Up, 그리고 다양한 현장에 시범 적용 및 결과 분석을 수행하였다. 현재 고속도로 건설 현장인 서부내륙 프로젝트 11공구 등의 현장에 실 적용되고 있으며, 이에 따라 다양한 측정 변수에 따른 모니터링을 실시하였다. 본 논문에는 그 중 친환경 건설 비산먼지 저감제의 유효 적용 거리에 대해 설명하고자 한다.
