  • The purpose of this study was to assess the microbiological quality of home-delivered meals during production and delivery for children from low-income families. Production flows from a facility in Seoul that provides home-delivered meals were analyzed and the time-temperature of the food was measured. Microbiological assessment was performed for the production environment, personal hygiene, and food samples at each production and delivery step based on the process approach. It took 2 hours or longer from completion of production to meal delivery. An aerobic colony count (ACC) and coliform were not detected at knives, cutting boards, and dish towels. However, ACC (at pre-preparation, preparation, and packing areas) and coliform (at the preparation area) were detected on the hands and gloves of employees. Air-borne bacterial counts varied according to day and preparation area (ND~6 CFU/plate/15 min). Food temperatures, on the completion of production and meal delivery, fell into temperature danger zones. ACC and coliform counts of raw ingredients did not decrease after pre-preparation (washing and sanitizing) for menus involving food preparation with no cook step. ACC decreased after cooking step for menus of food preparation with cook step, but the ACC of the stir-fried and seasoned dried filefish fillet on the completion of cooking was too numerous to count due to improper heating. The ACC of seasoned young Chinese cabbages (a menu with complex food preparation) increased during delivery (from 2.5 log CFU/ml to 5.0 log CFU/ml). This qualitative assessment of foodborne pathogens revealed that B. cereus was detected in vegetable and meat product menus. These results suggest time-temperature control is necessary during production and delivery and management guidelines during production of home-delivered meals are provided for safe production.

  • 목적: 이 연구의 목적은 세 가지 자가 평가 방법에 따라 치의학전문대학원 학생들의 치아 삭제 능력의 향상 정도를 비교하는 것이다. 연구 재료 및 방법: 경북대학교 치의학전문대학원의 2학년 48명 학생을 대상으로 3개의 실험 그룹으로 나누었다. 금관(gold crown)제작을 위한 좌측 하악 제1대구치의 치아삭제를 수행하였다. 세 가지 자가 평가 방법(시각적, 디지털, putty index 자가 평가 그룹)을 사용하여 자가 평가를 수행하고, 치아 삭제를 다시 수행했다. 구강 스캐너를 사용하여 각 치아(삭제된 치아 및 삭제되지 않은 치아)를 스캔하고 standard tessellation language (STL) 파일 형식으로 데이터를 저장하였다. 삭제된 치아와 삭제되지 않은 치아의 STL 파일은 3 차원 분석 소프트웨어(Geomagic control X)를 사용하여 중첩되었다. 그리고 삭제량을 측정했다. 통계적 분석에서, 삭제량의 모든 값은 Wilcoxon signed rank 및 Kruskal-Wallis 테스트로 분석하였다(α = 0.05). 결과: 세 가지 자체 평가 방법은 통계적으로 유의한 차이를 나타냈다(P < 0.001). putty index 자가 평가 그룹은 디지털 자가 평가 방법보다 교육 후 오차의 감소가 더 컸다. 결론: 이 연구의 한계 내에서, 학생들은 세 가지 자기 평가 방법에 따라 치아 삭제 능력의 개선에 유의한 차이가 있음을 보였다.

  • Environmental Impact Assessment System, ever since its enactment in Korea fourteen years ago, has been steadily improved by introduction and implementation of new concepts and methodologies which include Environmental Impact Statement(EIS) preparation technique, selection of environmental factors, and the like. However, current guideline requires that every EIS, regardless of the specifics of the project type or characteristics of the site, must evaluate and study for all twenty-two environmental factors as set forth in the regulation. The situation causes many undesirable problems like; lack of site specific evaluation in most EISs, over-sized EIS drafts, consuming too much time and costs for EIS preparation, and so on. The objectives of this study are: - To establish a set of criteria to classify the types of the projects in terms of features of the project content and the characteristics of the site area. - To establish a guideline for selecting major environmental factors of the project type criteria, and - To provide basic materials for the preparation of complets draft EIS of the Amendment of Environmental Impact Assessment Act.

  • Environmental Impact Assessment(EIA) in Korea has developed as a tool for environmental conservation and decision making since Environmental Impact Statement(EIS) preparation in 1981. For effective implementation of it, we do system development and method enhancement continuously. The recently introduced GIS (Geographic Information System) can integrate geographic and attribute data, which will be applied to scoping, assessment, and alternative assessment, etc. in EIA. This study has three major components. First, it explains building of EIA factors of natural environment, living environment, and socio-economic environment of the study area defined in EIS preparation regulation. Second, the study presents applications of assessment method concerning suitability analysis of landfill site using GIS. Finally, it shows integration of GIS and odor impact assessment. Based on these analysis, the study makes some recommendations and conclusions.

  • This paper seeks for the set-up plan in the reasonable target area of environmental assessment. Domestically, the target area of environmental assessment is set up by the adjustment of opinion collection about the assessment scope result of an environmental factor. In a foreign country, the boundary of the target area for a development project is established with the environmental, economical, and social viewpoint based on the standard for significantly environmental impact. Based on the analysis of the present condition at home and abroad, the first set-up plan for the reasonable target area of environmental assessment is the preparation of the detailed term definition related to the target area of environmental assessment. The second is the arrangement of the judgement standard for significantly environmental impact. The quantitative assesment item can apply the present standard or regulation, and the qualitative assessment item can establish the standard based on factual and objective data. The last is the preparation of the reference material or the guideline for deciding the initial target area by the judgement standard and determining the final target area by opinion collection in the stage of scoping.

  • The purpose of this study is to suggest a guideline that can be used as a standard for consultation and review by environmental impact assessment consultation and review practitioner to enhance the practical effectiveness of creating alternative habitats. The consultation stage of environmental impact assessment was significantly divided into 1) preparation of draft environmental impact assessment reports and gathering of consensus thereon, 2) preparation of environmental impact assessment reports and consultation thereon, 3) follow-up survey of environmental impacts(under construction) and 4) follow-up survey of environmental impacts(in operation). And it was suggested that the procedures of creating alternative habitat by each consultation stage were linked in order of 1) planning, 2) designing, 3) construction, and 4) post-monitoring and maintenance. The basic principles were also proposed for each stage of consultation on environmental impact assessment and procedure for the creation of alternate habitats. Then, issues and methods to be reviewed by the consulting agency and review agency of environmental impact assessment were presented in detail. The guideline of this study provides important information not only to environmental impact assessment consultation and review practitioner, but also to developers and environmental impact assessment agents who plan, construct, and manage alternative habitats.

  • 화학물질관리법에서 장외영향평가서 및 위해관리계획서를 화학사고예방관리계획서로 일원화하는 제도가 시행되었다. 화학사고예방관리계획서에서 다루는 유해화학물질 중 사고대비물질은 화학사고의 발생 가능성이 높거나 화학사고가 발생한 경우에 그 피해 규모가 클 것으로 우려되는 화학물질로서 지정하고 있다. 본 연구에서는 사고대비물질별 규정수량 기준에 따른 위험도를 비교하고자 상위/하위 규정수량이 비슷한 화학물질을 특정하여 동일한 사고 시나리오를 선정하고 위험도 평가를 실시하였다. 연구대상물질은 암모니아, 염화수소, 이황화탄소, 벤젠 등 총 4종의 물질을 선정하였으며, DNV 사의 정량적 위험성 평가 프로그램인 Safeti 8.0을 활용하여 위험도를 비교 분석하였다. 그 결과, 비슷한 상위/하위규정수량임에도 불구하고 상대적으로 높은 위험도를 가지고 있는 물질을 확인할 수 있었다.

  • The purpose of this study is to suggest improvements of Eco-Natural map preparation guideline by presenting assessment methods that can be applied to the result of river ecosystem health survey and assessment, using the Geographic Information System. The area for studying is the main stream of the Hwang River where is easy to collect data and available to compare before and after of river assessment. It was reevaluated by reflecting the result of river ecosystem health assessment of the Ministry of Environment. As the result, Eco-Natural map of the study area reflecting the river assessment, the changes in the area ratio by grade have been increased from 1.14% to 14.03% in the first-grade and from 24.64% to 43.91% in the second-grade. It is considered to present more realistic grade due to the assessment of the rivers that have not been reflected in the meantime. Consequently, the result of this study will be useful for establishing the development projects on the rivers, providing the foundation for more realistic and active protection.
