Through the recent pandemic, this study examined the theory of awe, which explains that external crises affect people's value systems and consequential behaviors. During the pandemic, some consumers expressed a growing interest in equity, while others pursued the consumption of materialistic items, such as luxurious fashion goods. According to the theory of awe, both of these phenomena could be coping responses to the crisis. Based on this, we attempted to understand the psychological processes behind the pandemic's effect on these two different consumers value systems thereby influencing sustainable consumption intentions: one through the new ecological paradigm (NEP) that emphasizes consumers' increased consciousness, and the other through materialism that emphasizes consumers' self-centered side. The results obtained from a survey of 382 U.S. consumers revealed that the degree of pandemic experience increased consumers' NEP and materialism, which also increased their economic and ethical CSR expectations. These CSR expectations then enhanced consumers' sustainable consumption intentions. As sustainable consumption and CSR are important agendas for the fashion industry, this study will provide useful insights for researchers and practitioners in the fashion field.

Greenhouse gas (GHG) emission from agricultural lands is recognized as one of important factors of global warming. The objective of this short communication was to evaluate the applicability of different soil GHG emission prediction models on agricultural systems in Korea. Four models, namely, DNDC, DAYCENT, EXPERT-N and COUP, were selected and the basic structure (e.g., components and sub-model), input variables, and output variables were compared. In particular, the availability and compilation of essential input variables were assessed. Major input variables needed for operating these predictive models were found to be available through database systems established by national organizations such as the Korea Meteorological Administration, the Korean Soil Information System, and the Rural Development Administration. However, in order to apply these models in Korea, it was necessary to calibrate and validate each of the models for the domestic landscape settings and climate conditions. In addition, field data of long-term monitoring of GHG emission from agricultural lands are limited and therefore should be measured.

In order to make plan for landscape construction by ecological methods in Yukong R & D Complex site, environmental factors and structure of plant community were investigated and analyzed around Yukong R & D Complex site of Daeduk. The result of this study were as follows: 1. In the result by the classification of TWINSPAN and ordination (DCA) techniques for analysing of plant community structure, thirty plant community structure, thirty plots were divided into four groups according to soil moisture and succession trends were seem to be from the development of subsidiary vegetation through Pinus densiflora, Quercus spp., Robinia psudoacasia community to Q. acutissima community. So this result was proposed to validity of vegetation introduction for planning of ecological landscape construction in studied site. 2. On the analysis of environmental factors by ordination techeniques, the plant community were divided by soil moisture. Soilcondition will be fertilized by introduction of broad-leaved tree and the development of succession trends from the present state of plant community to Q. acutissima community. 3. The problems of horiticultural places happened to studied site, so horiticultural places for ecological landscape construction was proposed planting techniques that were considered to soil suitability, economical efficiency, native species and wildlife. 4. If we attempt to ecological landscape designs on natural systems and use natural processes to achieve desired end-points, we are more likely to produce self-sustaining solutions.

Background: Satisfactory completion of mine safety training is a prerequisite for being hired and for continued employment in the coal industry. Although training includes content to develop skills in a variety of mineworker competencies, research and recommendations continue to specify that specific limitations in the self-escape portion of training still exist and that mineworkers need to be better prepared to respond to emergencies that could occur in their mine. Ecological models are often used to inform the development of health promotion programs but have not been widely applied to occupational health and safety training programs. Methods: Nine mine safety trainers participated in in-depth semi-structured interviews. A theoretical analysis of the interviews was completed via an ecological lens. Each level of the social ecological model was used to examine factors that could be addressed both during and after mine safety training. Results: The analysis suggests that problems surrounding communication and collaboration, leadership development, and responsibility and accountability at different levels within the mining industry contribute to deficiencies in mineworkers' mastery and maintenance of skills. Conclusion: This study offers a new technique to identify limitations in safety training systems and processes. The analysis suggests that training should be developed and disseminated with consideration of various levels-individual, interpersonal, organizational, and community-to promote skills. If factors identified within and between levels are addressed, it may be easier to sustain mineworker competencies that are established during safety training.

This study evaluated ecological health, using various biomarkers and bioindicators, of pale chub (Zacco platypus) as a sentinel species, in Daejeon Stream, South Korea, during AprilMay 2011. The biomarkers and bioindicators were compared among three sites of control: Reference ($C_z$), transition ($T_z$), and the urban zones ($U_z$); and the 7-Ethoxyresorufin-O-deethylase (EROD) activity, DNA damage, acetylcholinesterase (AChE) activity, and vitellogenin (VTG) concentrations were more significantly increased in the $U_z$ than in the $C_z$. Also, physiological markers such as condition factor, liver somatic index, visceral somatic index, and gonad somatic index were significantly increased in the $U_z$ than in the $C_z$. For the health assessments, three categorized parameters of blood chemistry, molecular biomarkers, and physiological bioindicators were standardized and calculated as a star-plot, representing values of Integrated Health Response (IHR). Values of IHR had more significant (P<0.05) increases in the $U_z$ than any other zones, indicating an impairment of ecological health by organic matter, nutrients (N, P), and toxic chemicals. This study is based on low levels of biological organization approach of molecular and physiological biomarkers and bioindicators, so further study of high-levels of biological organization approach such as community and population is required for overall range of health assessments. The approach of IHR values, however, may be useful in providing early warning of future impacts on ecological health.

The purpose of the present study was to compare the long-term management objectives, policy objectives, implementation plans, and detailed plans of four provincial parks established in 2013 using various analysis frameworks. Through this, the study aimed to identify the characteristics of the management plan and extract the implementation plan important to each park by analyzing the priorities in the detailed plan. The long-term management objectives of most parks were to maintain recreational functions by utilizing all the resources of the park, rather than merely preserving the ecosystem. From an ecological perspective, information on major plants and legal protection species are included for most parks, and geological and topographic features considered a major resource. For sustainable forests, it is important to induce the dispersion of concentrated use space. Efficient management systems are distinctively differentiated among the parks. For regional revitalization, the management of programs to link provincial parks and their surrounding areas has become most important. From an ecological perspective, priorities differed for the parks according to their ecological characteristics. For sustainable forests, Moaksan Provincial Park prioritized the visitor reservation system related to the overall park, while the other three parks prioritized alleviating the concentrated use of specific areas. From an efficient management perspective, Daedunsan Provincial Park prioritized aspects related to the cableway. Maisan Provincial Park prioritized inducing the linkage between the use of natural and cultural resources, and Seonunsan Provincial Park prioritized establishing an ecological and cultural commentary operating system. For the base-type leisure activity space, Moaksan Provincial Park prioritized the systematic management and operation of the pilgrimage route, Maisan Provincial Park the connection between the Maisan geography and residents' income, and Seonunsan Provincial Park providing a space for ecological education.

Many countries have run their own certification systems in order to reduce the environmental loads from buildings. Domestically, various systems are applied according to building types from Building Energy Efficiency Rating System since 2001 to Green Home Construction Standard and Performance since 2009. However, these systems provide the applicants with confusion and waste by exposing them to several systems simultaneously, some of which are mandatory. Therefore, this study aims to ensure the flexibility among those systems and eliminate the possible waste by suggesting mutual accreditation method of evaluation results. To achieve this purpose, firstly, the thirteen similar evaluation items are identified between Housing Performance Grading Indication System and Green Building Rating System. Then, the mutual accreditation method is developed by comparing detailed evaluation criteria and credits for those thirteen items.

Biological assessments are the primary tool for evaluating the biological condition of a water body and makes it possible to understand accumulative and long-term effect of stressors. They also provide reliable biological information for which disturbed systems are to be restored. Sustainable water environment is not enough with attaining only the clean water, but it should sustain healthy and diverse aquatic life. Aquatic organisms are affected by various factors, including not only water quality but also habitat condition and stressors, and thus good condition of both physical and chemical water quality is prerequisite for sustaining healthy organisms. Therefore, biological assessment, along with other physical and chemical assessments, are crucial for evaluating the health of a water body. Overall, sustainability of water environment demands the attainment and maintenance of ecological integrity, which is resulted from the combination of physical, chemical and biological integrity. The biological criteria will play very important role in the water resource management and policy issues, and thus bioassessment program should be fully implemented and supported eventually by the law. To keep ecosystem health of water environment safely from the toxic pollutants and other stressors, the following suggestions need to be considered in environmental quality standards in Korea. For the first step, the biological indicators need to be introduced in evaluating river quality condition; they provide a qualitative description of biological condition of water body. Secondly, the biological water quality standards using biotic indices should be developed and implemented under the consideration of characteristics of Korean river systems. Lastly, the ecological status classification regime (ESCR) should be developed and introduced; it could be used in quality assessment of the water environment in general. In developing ESCR, integration of physico-chemical, biological, and habitat parameters should be taken into account.
