Industrial wastewater often contains a number of recalcitrant organic contaminants. These contaminants are hardly degradable by biological wastewater treatment processes, which requires a more powerful treatment method based on chemical oxidation. Advanced oxidation technology (AOT) has been extensively studied for the treatment of nonbiodegradable organics in water and wastewater. Among different AOTs developed up to date, ozonation and the Fenton process are the representative technologies that widely used in the field. Based on the traditional ozonation and the Fenton process, several modified processes have been also developed to accelerate the production of reactive radicals. This article reviews the chemistry of ozonation and the Fenton process as well as the cases of application of these two AOTs to industrial wastewater treatment. In addition, research needs to improve the cost efficiency of ozonation and the Fenton process were discussed.

<배경 및 목적> Hepatitis B virus (HBV) 감염은 급성 간염, 만성 간염, 무증상의 보균상태, 간경변, 그리고 간암에 이르기까지 넓은 범위의 임상 양상을 보인다. HBV 감염과 연관된 간 손상은 주로 면역 기전에 의해 매개되고 있는 것으로 알려져 있으며 바이러스의 유전적 다양성에 의해 영향을 받을 수 있다고 보고되고 있다. HBV는 HBsAg의 antigenic determinants에 따라 9개의 서로 다른 subtype으로 나뉜다.

Background / Aims : Hepatitis B virus(HBV) genotype have distinct geographic distributions. The possibility of pathogenic difference among HBV genotypes has been suggested. We investigated the prevalence of HBV genotypes in Korea and the association between distinct genotypes and clinical outcomes. Methods : Using a PCR-RFLP and sequencing, HBV genotypes were determined in 136 patients with chronic type B hepatitis. Results : The genotype C was detected in 131 patients(96.3%), and other 5 patients(3.7%) had genotype B. There were no significant differences in sex, age, disease duration, ALT level, HBeAg/anti-HBe status, or HBeAg loss between genotype B and C patients. Conclusion : These results suggest that almost all patients with chronic hepatitis B are infected with genotype C. Genotypes do not influence the outcome of chronic hepatitis B patients in Korea.
