Bioaerosols generated from composting facilities and landfills may create health risks for workers and nearby residents. To determine the levels of culturable airborne bacteria and fungi in bioaerosols, samples were seasonally collected at a composting facility and a landfill in Ulsan, Korea with an impaction-type sampler. Concentrations of heterotrophic bacteria averaged (in $MPN/m^3$) $6.5{\times}10^3$ (range $1.5{\times}10^2-1.5{\times}10^4$) in the composting facility and $3.9{\times}10^3$ (range $6.0{\times}10^1-9.3{\times}10^3$) at the entrance of the facility. These concentrations were 460 and 280 times higher than those of reference sites. Coliform bacteria were detected both inside and entrance of the facility. On the landfill, heterotrophic bacterial concentrations averaged (in $MPN/m^3$) $4.9{\times}10^2$ (range $1.7{\times}10^2-1.0{\times}10^3$), while they averaged $3.7{\times}10^2$ (range $4.8{\times}10^1-1.3{\times}10^3$) at the parking lot of the landfill. These concentrations were 35 and 26 times higher than those of reference sites. When we isolated and tentatively identified heterotrophic bacteria, Pseudomonas luteola was the most dominant species in bioaerosols from the composting facility, whereas the most abundant one in reference samples was Micrococcus sp. Average concentrations of airborne fungi were measured between $4.8{\times}10^2$ and $7.9{\times}10^2\;MPN/m^3$ depending on sites, which were 2.1-3.4 times higher compared to those of reference sites. While Cladosporium, Alternaria, and Penicillium were commonly identified fungal genera, genus Aspergillus was identified only in bioaerosols from the composting facility.

현대 산업사회가 다양해짐에 따라 발생되는 생활폐기물의 형태도 다양화되었고 발생폐기물의 성상은 연소가 어려운 난분해성 폐기물로 발열량이 높아지고 있다. 이러한 폐기물의 처리를 위한 소각설비는 폐기물 처리형태에 따라 대형의 도시 쓰레기 소각장이나 지자체의 중형급 소각장, 발생원 단위의 소형 소각장으로 구분하여 처리하고있다. 기존 중ㆍ대형 소각로의 유해가스 처리시설은 일반적으로 냉각설비와 가스상 처리설비, 입자상 처리설비 등으로 구성되는데 반해, 소형 소각로는 싸이클론 방식만으로 구성되어 입자상 물질만을 처리하였으나, 최근에 들어서 관련법규가 개정되어 소형 소각로에서도 입자상 오염물질뿐만 아니라 HCl 및 SOx 등과 같은 산성가스류와 다이옥신 등의 배출농도를 규제함에 따라 가스상 오염물질도 처리하는 방안을 도입하고 있는 추세이다.

학교 도서실은 단지 자료를 축적해 놓은 자료실로서의 역할만을 목적으로 이용하는 곳이 아니라, 학습활동, 독서활동 자료 및 정보제공, 그리고 레크리에이션의 장으로서의 기능을 가지고 있다. 즉 학교의 도서실은 일반 공공도서실과는 다른 학교의 교육목표 달성을 위한 가장 기본적인 교육공간으로 자아학습의 장이다. 지식정보화시대를 맞이하여 자기주도적인 학생중심의 학습을 위한 독서활동과 다양한 자료의 활용이 없이는 불가능하며 학교 도서실을 이용하지 않고서는 그 효과를 기대하기 어렵다. 단지 장서수와 컴퓨터 등의 물리적인 수치가 더 이상 지표가 되어서는 안 되고 학생들의 정서함양 및 인격소양에 도움이 되는 독서공간을 통한 청소년기의 마음의 안정을 제공해 줄 수 있는 진정한 자아학습의 장으로 거듭나야 할 것이다. 본 고에서는 문화관광부의 문화로 아름답고 행복한 학교만들기 사업 가운데 선정된 도서공간의 재구축 사례에 대해 소개하고자 한다.

This study was carried out to investigate food service management practices in various operation types of child care center in Gyeonggi area of Korea, and to provide basic information for improving food service management policies at child care centers. Self-administrated questionnaires were collected from 102 child care center directors. The statistical analysis was completed using SPSS ver. 18.0 program. Approximately 97.1% of the directors were women. The number of total children were difference in public, private and home care centers respectively (p<0.001), and time of operation was significantly (p<0.01). Only 8.9% of the centers employed a dietitian, whereas 92.5% of the centers employed cook or assistant cook, thus food service was not managed by professionals in most centers. All of the centers had been self-operated and meals were prepared in a conventional manner. In approximately 89.2% of the centers servings snacks twice a day. Menu planner of the centers which have no dietitian was the child care information center (47.5%) or the director (34.7%). In most centers, the directors was also purchasing manager and 36.0% of the center purchased food every day. These results indicated that food service management guidelines need to be established by the child care center type with the government control and financial support. We recommended that they furnish the efficient food service program for food service management.
