Challenges brought by applications of advanced technologies in education call for new approaches that can best ensure the provision of quality e-learning experiences. This paper presents an ecological approach as one of such approaches to quality assurance in e-learning that can monitor, assess and improve the effectiveness and the links between the various elements of e-learning. The ecological model for QA in e-learning emphasizes interrelation transactions between elements (e.g. providers, learners, cultures and policies) and systemic integration of those elements, and stresses that all these elements within a QA system play an equal role in maintaining balance of the whole. The model focuses attention both on individual and societal/cultural environmental factors as cornerstones for QA efforts in e-learning. It addresses the importance of QA efforts directed at changing QA transactions from provider-centered to 'all stakeholder-oriented', from one-size-fits-all model to 'globally oriented, locally adaptive model' and from control framework to 'culture creation framework'.

In view of the problem of the invalidity of the incentive mechanism of the ecological subsidies, which is due to the information asymmetry between the government's supervision and the enterprise endeavor to fulfill their ecological responsibilities, this paper attempts to analyze the supervision of ecological subsidies based on the Principal-agent Model. Two conclusions are drawn: firstly, the government's supervision regarding the effect of the enterprises' fulfilling the ecological responsibilities can significantly reduce the information asymmetry; secondly, the government's incentive strength and the enterprises' endeavor level of fulfilling the ecological responsibilities are both improving the surveillance dynamics. Here is the suggestion: with the increasing of the surveillance dynamics of the government and the transparency of the enterprises' fulfilling the ecological responsibilities, the government should meanwhile increase the subsidies incentive strength, therefore, to promote the effort level of the enterprises' fulfilling the ecological responsibilities to approach to the Pareto optimal value.

The objective of this research was to develop ecological multi-metric models using natural fish assemblages for a diagnosis of current stream health condition, and apply the model to nationwide lotic ecosystems of the Geum River, the Youngsan River, and the Sumjin River. The ecological stream health model was based on the index of biological integrity (IBI), which was originally developed in North American streams by Karr (1981), and the Rapid Bioassessment Protocol (RBP), which was scientifically established by the US EPA (1999). The metric numbers and metric attributes were partially changed for the regional applications, so the scoring criteria was modified for the assessment. Overall, metric values, based on the IBI calculations, reflected conventional water quality characteristics, based on nutrient regime, and agreed with results of staticeco-toxicity tests. Some stations impaired in terms of stream health were identified by the IBI approach, and also major key stressors affecting the stream health were identified by additional evaluations of physical habitats. Our preliminary results suggested that biological integrity in stream ecosystems was largely disturbed by habitat degradation as well as chemical pollutions. This new approach would be used as a key tool for ecological restorations and species conservations in the degraded aquatic ecosystems in Korea and applied for elucidating major causes of ecological disturbances. Ultimately, this approach provides us an effective management strategy of stream ecosystems through establishments of ecological networks in various watersheds.

Purpose: This study aimed to develop hypertension control programs and to analyse their effects in small scale enterprises(SSE). Method: One program was based on 'Transtheoretical Model and Stages of Change' and named 'Individual Approach'. Another program was based on 'Ecological Model' added to the former theory and named 'Integrating Approach'. The target population of the programs are 33 and 34 workers each. The two intervention programs were conducted for 18 weeks after a pre-intervention survey. Immediately after the programs end, first post-intervention survey was done, and second post-intervention survey was done after 28 weeks. Results: First, at the beginning of intervention, the target workers were evenly distributed over the five stages of Transtheoretical Model. But after the intervention, all workers were found in the maintenance stage. Second, the blood pressure level was diminished in the two programs. In Individual Approach, the workers have lost systolic blood pressure by 17.3 mmHg and diastolic blood pressure by 11.8mmHg. In Integrating Approach, the workers have lost systolic blood pressure by 20.0mmHg and diastolic blood pressure by 15.0mmHg. Conclusion: Integration Approach is more favorable than Individual Approach as an intervention program of hypertension in small scale enterprises.

The purpose of this study was to propose theoretical-practical strategies of family-based intervention for the "Healthy Family-Support Center." The theoretical background used was an ecological approach, that is, taking viewpoints of client family's microsystems as well as those of exo- and macrosystems. This study raised several critical points in researching and developing family-based intervention programs. Based on a review of the literature, the study indicated why an ecological, family-based intervention model was a relevant alternative to investigate issues in family welfare and to deliver possible assistance and solutions for them.

The purpose of the study was to develop family-based intervention program to be implemented and disseminated via "Healthy Family-Support Center." This preventive-empowerment program was designed to intervene with parenting mildly handicapped children enrolled at integrated kindergarten. The theoretical backgrounds employed were ecological theory, preventive family-based intervention approach, and theraplay theory. The pretest-posttest control-group design with random assignment was applied. The research model yielded a significant intervention effect(t=-1.294, p<0.05) on mothers' parenting stress. With proven effectiveness of family-based intervention program, the study further discussed why an ecological, family-based intervention model was a relevant alternative to investigate issues in family welfare, and why an individualized family service plan was a relevant tool to deliver services-in-context for the families who needed supports from exo-and macrosystems.

Objectives: This study is to draw the design of the program which is improve school health promotion participation by applying the Social Ecological Model based on the literature review on the health promotion. Methods: Literature review was carried out based on 5 factors of social ecological model using computer search engines of Google, ProQuest, and Riss4U. Results; Social Ecological Model is consist of individual, interpersonal, institutional/organizational, community, and policy. Individual sphere is drawn from Health Belief Model, interpersonal sphere is Social Support Theory, institutional/ organizational sphere is institutional resources theory, community sphere is community model, and policy sphere is Social Marketing Theory. The literature review show that the important variables affecting health promotion exist in each sphere. Individual sphere has social economic status, age, sex, sensitivity and specificity of illness, self-efficacy. Interpersonal sphere has support and use of family, friend and neighbor. Institutional/Organizational sphere has environment service reliability and utility. Conclusions: Community sphere has distance, neighborhood safety, interrelationship among institutions. Policy sphere has cost, legislation advertisement, lobby and concern and leadership of Institution.

This research developed an approach to identify ecologically important areas at local scales and explained how the results of this approach could contribute to extend the protected areas in the Republic of Korea (ROK). While most developed countries have considered various biotic and abiotic factors, ecological processes, migration routes, habitat connectivity, ecosystem services, and etc. to determine the protected areas, ROK has considered a few factors focusing on biodiversity, landscape, and the habitats of endangered organisms. However, for sustainable management of our nature, we need comprehensive understanding of various ecosystem factors and interactions among them at local scales in designating protected areas. Forthis, we developed a conceptual model based on the ecological engineering approach and then explained how the results of this approach could contribute to extend the protected areas. In particular, we considered future land-use and climate change in determining the priority areas for novel protected areas. Our research suggested an effective methodology 1) to include various ecosystem factors and 2) to consider future environmental changes as well as current environmental conditions in finding the ecologically important areas and prioritizing these areas. However, our approach has limitations on the real-world applications due to the lack of fundamental information and data on our ecosystems. To improve the effectiveness of our approach in the real-world applications, we need various long-term ecological research results, environmental and ecological monitoring data, and both current and future spatial environmental data.
