지하철 구내의 대기 중 $SO_2$, TSP 농도와 대기 허용기준에 관한 연구
김성천 한국환경보건학회 1993 한국환경보건학회지 Vol.19 No.1
The airborne concentrations of Sulfur Dioxide and Total Suspended Particulates were investigated in 4 subway lines in Seoul at early summer, 1990 and early summer, 1991. The results of the study were as follows: 1. The airborne concentrations of SO$_2$ and TSP were 0.022 ppm, 445.7 $\mu$g/m$^3$ respectively. And percents of over annual air quality standard of WHO was that SO$_2$ and TSP were 41.7%, 100% respectively. 2. Airborne SO$_2$ concentrations by subway lines were that line 1 was 0.025 ppm, line 2 was 0.023 ppm, line 3 was 0.020 ppm, and line 4 was 0.017 ppm. And TSP concentrations by subway lines were that line 2 was 533.8 $\mu$g/m$^3$, line 1 was 516.5 $\mu$g/m$^3$, line 4 was 371.6 $\mu$g/m$^3$, and line 3 was 369.3 $\mu$g/m$^3$ 3. Annual variation of concentration of TSP was not significant statistically (t=0.327), and that of SO$_2$, in 1990 was slightly higher than that in 1991 (t=1.433, p<0.1). 4. Coefficients of correlation between TSP and SO$_2$ by years were that early summer, 1990 was r=0.277 (p>0.1), and early summer, 1991 was r=0.32 (p>0.1).
소비자정책의 최근 동향 - 2004년과 2005년을 중심으로 -

The years 2004-2005 saw some landmark developments in the nation’s legal framework for consumer protection policy. These legislative initiatives were designed to secure effective measures for protecting consumer rights in the face of radical changes brought about by the rapid spread of undue electronic commerce transactions and unfair adhesion contracts, etc. The Adhesion Contracts Act was revised to prevent consumer damage caused by Unfair Adhesion Contracts. The new standard adhesion contract regulation system was introduced to prevent use of any adhesion contract containing unfair terms and conditions. The Consumer Protection Act on Electronic Transaction, etc was revised to prevent consumer damage caused unduc electronic commerce transactions. The payment escrow system and Do-not-Call system will be introduced to prevent consumer damage caused by prepaid distant selling and internet fraud. And the Korean Consumer Policy will undergo major changes. According to the ‘Mid-to-Long Term Road Map on Consumer Policy’ of the Ministry of Finance & Economy (MOFE), the Consumer Protection Act will change to the Consumer Fundamental Law (tentative name). Also the Consumer Class Action Lawsuit will go into effect.
