Korea is now classified as an area of intermediate endemicity for hepatitis B virus (HBV), due to the implementation of universal HBV vaccination and national preventive programs for HBV infection. A national program of HBV vaccination was launched in Korea in 1988 for school-going children and was listed on a vaccination guideline in 1991. In 1995, universal vaccination for newborn infants was started for the prevention of perinatal HBV transmission. The prevalence of HBsAg among Korean middle school students has shown marked decreased from 3.2% in the late 1990s to 0.44% in 2007. HBsAg positivity in preschool children was 0.9% in 1995, decreased to 0.2% in 2007 by national prevention program of hepatitis B vertical transmission, launched in 2002. Vaccine failure rate of HBV immunoprophylaxis is 4.2% by this program. The infected children should be monitored per 6-12 months interval. Lamivudine and interferon are approved therapies for children with chronic hepatitis B in immune-clearance phase in Korea.

This study examined the developmental characteristics of friends and disliked peers in 169 children and adolescents, including 44 preschool children, 43 primary school, 42 middle school, and 40 university students. Their descriptions of 2 same gender friends and 2 disliked same gender peers were categorized with an 81 category coding system. Comparisons across age and sex were made by a cross-tabulation test. Results showed that the reported characteristics of friends and disliked peers varied by age, but there was no sex difference. That is, younger children liked their friends because they played together, their friends were generous and attractive, but older children liked friends because they had some similarity, were reliable allies, caring and concerned. Younger children's disliked peers were aversive, aggressive and hyperactive while older children's disliked peers were dissimilar and snobbish.

Objectives: The Korea Ministry of Environment regulates concentrations of hazardous air pollutants (HAPs) through Atmosphere Environmental Standards to protect public health from HAPs. However, simply determining the exceedance of HAP concentrations has several limitations and more comprehensive assessment is required. In addition, integrated risk assessment is needed considering exposure in all microenvironments, including outdoor as well as indoor environments. The purpose of this study was to assess the differences in risk by sub-population groups according to time-activity patterns and reported concentrations, as well as the lifetime risk for Koreans. Methods: In this study, we calculated time-weighted average exposure concentrations for benzene and $PM_{10}$ among preschool-age children, students, housewifes, workers, and the elderly using residential time and concentrations for indoor (house, school or workplace, other), outdoor, and transport by the meta-analysis method. The risk assessments were conducted by excess cancer risk and disease death risk using 1,000,000 Monte-Carlo simulations for probabilistic analysis. Results: Preschool-age children, students, housewifes, workers, and the elderly spent 91.9, 86.0, 79.8, 82.2, and 77.3% of their day in their house, workplace, or school, respectively. The more than 99% excess cancer risk for benzene exceed 1.0E-06 in all sub-populations and lifetime. The acute disease death risk for $PM_{10}$ for housewifes and workers for lifetime were 3.35E-04 and 3.18E-04, and chronic disease death risks were 2.84E-03 and 2.70E-03, respectively. Conclusions: The risk of benzene and $PM_{10}$ by sub-population group and for the lifetime of housewifes and workers were assessed. Benzene showed risky results for this study. All disease death risks of $PM_{10}$ were higher than 1.0E-04 and showed different risks by sub-population. This study can be used as a basis for lifetime exposure and risk assessment to benzene and $PM_{10}$.

Objectives: Although the risk assessments for nitrogen dioxide ($NO_2$) and ozone ($O_3$) have been extensively studied, most of the existing risk assessments were limited mainly to indoor environments such as workplaces, schools, and multi-use facilities. Therefore, integrated risk assessment is needed to consider exposure in all microenvironments, including outdoors. The purpose of this study was to assess the differences in risk among sub-population groups according to time-activity patterns and reported concentrations, as well as the lifetime risk of Koreans. Methods: In this study, we estimated time-weighted average exposure concentrations of $NO_2$ and $O_3$ for preschool children, students, housewives, workers, and seniors using residential time and indoor concentrations (house, school or workplace, other), outdoors, and transport by meta-analysis method. The risk for $NO_2$ and $O_3$ were assessed by hazard quotient using reference concentrations 30 and 60 ppb, respectively. The risk assessments were conducted through 1,000,000 Monte-Carlo simulations for probabilistic analysis. Results: Preschool children, students, housewives, workers, and seniors spent 91.9, 86.0, 79.8, 82.2, and 77.3% of their day in a house, school, or workplace, respectively. The risk assessment for the lifetime of a housewife and a worker showed that 33.8 and 28.4% of hazard quotients of $NO_2$ exceed 1, respectively, and more than 99% of hazard quotient of $O_3$ were less than 1. Conclusions: The risk of $NO_2$ and $O_3$ by sub-population group and for the lifetime of housewives and workers were assessed. The risk for $NO_2$ was higher than for $O_3$ and showed a different risk by sub-population group. Both $NO_2$ and $O_3$ showed a higher risk for housewives than for workers. This study can be used as a basis for lifetime exposure and risk assessment for $NO_2$ and $O_3$.

시각과 시간은 학교수학의 내용 요소 중 일상생활에 필수적인 수학적 개념이다. 본 연구는 초등학생들의 시각과 시간에 대한 수학적 이해 실태를 분석하고, 그 결과에 기초하여 시각과 시간에 대한 이해 신장을 위한 효과적인 수업 설계 및 교재 개발에 대한 시사점을 도출하는 것을 목적으로 한다. 구체적으로 초등학교 1~5학년 각 1개 학급 학생 약 130명을 대상으로 시각 인식 및 시간 계산 수행 검사지를 적용하고, 그 결과를 토대로 하여 연구 대상의 수학적 이해 정도를 분석하였다. 분석결과, 학생들의 시각 인식 능력은 높았으며, 학교수학에서 몇 시 몇 분의 학습이 완료되는 2학년 시기에 완성됨을 알 수 있었다. 시간 계산은 학년에 따라 차이가 있고, 시각과 시간 학습이 완료되는 시기인 3학년 이상의 학생들도 어려움을 겪는 문항이 있음이 확인되었다. 분석 결과에 기초한 논의로부터 시각과 시간의 수학적 이해 제고를 위한 교수학적 시사점을 제안하였다.
