The KOrea Insecticide Exposure Model (KOIEM) was developed to facilitate ecological risk-based management of Korean insecticides. KOIEM, applied as a multimedia fate model, evaluates water, soil, air, and vegetation compartments based on three water-body types (streams, ditches, and ponds). Deltamethrin, a pyrethroid insecticide, was used to evaluate and create the model parameters. After exposure of both the stream and the ditch to deltamethrin, the KOIEM-predicted concentrations and the observed levels were in agreement. The model was also evaluated using the accuracy factor (AF), which was 4.32 and 0.35 for the stream and ditch, respectively. Ecological risk assessment was also performed to evaluate the application of KOIEM for four popular South Korean insecticides (cypermethrin, deltamethrin, diazinon, and permethrin). Despite the insecticides having low PECs in water, their risk quotients were typically above 1.0. Thus, KOIEM modification would be required in further studies to account for spatial variation.

The purpose of this study was to verify a Structural Equation Model that constructed the causations among the structural leisure constraints, interpersonal leisure constraints, intrapersonal leisure constraints, leisure motivation, leisure activity participation, leisure satisfaction and the quality of life from the ecological perspective. The respondents were 301 elderly people residing in 4 free institutionalized elderly homes in Seoul. The data were analyzed by confirmatory factor analysis and covariance structure analysis using USREL 8.0 ver. The major results are summarized as follows: 1) Statistically, a goodness of fit is good of structural equation model presented in the study. 2) The structural leisure constraints and the interpersonal leisure constraints are some types of leisure environment of the aged in public homes from the ecological perspective. Such constraints would inevitably lead to a direct effect on individual leisure life and leisure motivation. 3) The important valuable factor which affected the leisure satisfaction and the quality of life in the elderly was the leisure motivation.

Purpose: To investigate the behavioural factors of the health promotion for caregivers based on a socio-ecological model. Methods: This study was a cross-sectional descriptive study using a self administered questionnaire. The survey was conducted in 219 people chosen through convenient sampling between September and December 2008. The collected information included general characteristics, individual, interpersonal, community, policy level. Results: For the statistical analysis, the t-test was used for the health promotion according to the general characteristics and to each level of the socio-ecological model, by assessing the high and low values and dividing them into mean points. The influence elicited by different health promotion factors was determined using the hierarchical multiple regression. At the individual level, the factors influencing health promotion in caregivers included perceived seriousness, perceived benefits, and self efficacy. Social support was important at interpersonal level, and the use of community resource was relevant for the community level. We found no statistically significant factors relating to the policy level. Conclusions: In conclusion, the socio-ecological models seems appropriate for explaining health promotion and its associated factors in caregivers. We suggest that, for caregivers, strategies should be developed for their social support and to offer information about how to use community resources in relation with factors relating to the individual level.

The purpose of this study was to identify the educational and ecological factors (environment and infra-structure) associated with workers' participation to safety and health education at work (SHEW) based on the PRECEDE constructs. A total of 590 workers (484 in manufacturing and 106 in construction companies) finished the self-administered survey. Survey packets were delivered to the safety and health manager (SHM) in survey companies and the SHMs conducted the self-administered survey in their companies. The questionnaire includes demographics, epidemiological constructs, and educational and ecological constructs based on the PRECEDE model. Participation to SHEW was better in the manufacturing sector than in the construction sector (p<.001). Environmental, reinforcing, and enabling factors were better in the manufacturing companies than in the construction companies. Male worker, better perceived efficacy of SHEW, higher social support for SHEW, assignment of SHM at work, and better safety and health management level at work were significantly associated with workers' better participation to SHEW (p<.05). Those factors accounted for 45.9% of total variance of workers' participation to SHEW.

최근 하천복원 사업은 하천의 이수 및 치수 기능과 함께 생태적 기능을 고려한 방향으로 진행되고 있다. 생태적 건강성과 다양성이 증대된 하천으로의 복원을 위해서는 하천 내 제방과 같은 종적구조물로 의해 차단된 공간에서의 수리수문 연결성 회복이 중요하다. 본 연구에서는 차단된 공간에서의 생태적 연결성 분석에 필요한 수리수문자료의 제공을 위한 첫번째 단계로써 강우에 의한 유역유출 및 하도흐름 해석이 동시에 가능한 1차원 수치모형을 개발하였고, 이를 청미천 유역에 적용하였다. 수치해석 결과는 실측 자료 및 타 모형의 수치해석 결과와 비교하였고, 그 결과 잘 일치함을 알 수 있었다. 본 연구의 결과는 생태적 변화를 예측할 수 있는 자료의 제공을 위해 장기적인 수리수문분석이 가능하도록 보완될 예정이다.

The purpose of this study is to clarify the actual condition of real certification schools of environment-friendly architecture per ecological environment elements through extracting ecological environment elements which is possible to analyze in quantity certification standards of environment friendly architecture. As the method of this study, firstly, certification as an examination on certification system of environment-friendly architecture, summary of certification system of environment-friendly architecture and eco-school pilot model project, ecological environment elements which is possible for quantitative analysis of ecological environment certification standards were extracted. Secondly, actual condition of ecological environment elements per school grade by collecting actual data of certification schools environment-friendly architecture were analyzed. The average of ecological area ratio was 24.5 percent in case of this certification regardless of school grade and region and it was analyzed that the natural based green area ratio was 22.9 percent, bio-tope area ratio was 0.60 percent and ecological learning places area ratio was 0.39 percent.

The watersheds are functional geographical areas that integrate a variety of environmental and ecological processes and human impacts on landscapes. Geographical assessments using GIS recognize the relationship between interdependence of resources and ecological/environmental components in watersheds. They are useful methodology for viable long term natural resource management. This paper performs through the using hydrological analyses, landscape ecological analyses, remote sensing, and GIS. Indicators are items or measures that represent key components of the small watersheds, and they are developed to be evaluated. Some indicators are described that they represent watershed condition and trend as well as focus on physical, biological and chemical properties of small watershed. Also, ecological functions such as stability, resilience, and sensitivity are inferred from them. The model implemented in GIS allows to reflect the ecological and hydrological functioning of watershed. Methodology from image analysis, landscape ecological analysis, spatial interpolation, and numerical process modeling are integrated within GIS to provide assessment for eco-logical/environmental condition. Results are described from the small watershed of Gwynns Falls in Baltimore County and Baltimore City, Maryland, an area of about 66.5 square miles. The small watershed within Gwynns Falls watershed are subject to a number of land-use. But it is predominantly urban, with significantly lesser amounts of forest and agriculture. The increasing urbanization is ass-coiated with ecological/environmental impacts and citizen conflicts.
