The purpose of this study were (1) to investigate the effect of environments on the ecological value orientation (2) to examine the effect of environments and ecological value orientation on housewives' recycling behavior and (3) to analyze the hypothesized causal model of the housewives' recycling behavior in order to explain direct and indirect effects of the selected variables. 687 samples were selected from housewives living in Seoul. Cronbach's a, descriptive statistics and stepwise multiple regression were used for data analysis The major findings are as follows: Housewives' recycling behavior In conclusion the result of the path analysis explained the contribution of variables on housewives' household recycling. It was found that the ecological value orientation makes the most significant contribution to household recycling.

Soft shores are particularly vulnerable to human exploitation; however, they exhibit a variety of habitats which provide refuge for a diversity of flora and fauna. This study describes a survey of 13 soft shores in Hong Kong with information on species diversity, sediment characteristics, shore extent, pollution threat, degree of naturalness, linkage with other ecological habitats, and degree of social/economic importance. Data collected were subjected to multivariate statistical analyses, so as to identify shores that have significant ecological status and conservation value for management purposes.

To protect water pollution and scarcity in lake and river, water quality monitoring applications have become important tools to understand the change of aquatic ecosystem. KLEON (Korean Lake Ecological Observatory Network) is designed to manage and share the ecological observations. The various kinds of water quality and phytoplankton observations are collected from the selected observatories such as seven lakes/rivers/wetlands. To deeply understand the collected observations with weather, KLEON also manages the observatory information such as lake, dam, floodgate, and weather. The accumulated observation and analyzed results are used to improve the water quality index of the observatories and encourage the ecologists' cooperation.

This paper aims to analyze ecological characteristics of interior design, selecting as the subjects Busan-based construction companies which have a model house, among those that distribute apartments in Busan as of August 2006. Primarily, literature research Is conducted to understand recent trends of interior design for apartment building, present situations and characteristics of ecological design, and prepare environmentally-friendly guidelines and check-list items on the basis of domestic and overseas cases. Collected data in turn is analyzed to assess ecological characteristics of apartment building design in Korea today and present problems and directions for the future.

It is widely recommended that teachers should actively mediate students' engagement with tools such as manipulative materials. This paper is to help to parse classroom life so that both social and psychological aspects are accounted for and coordinated. Building on the theory of affordances from ecological psychology and the activity theory from sociocultural perspectives, the main strategy of this paper is to view manipulative materials as simultaneously participating in social and psychological activity systems. Within these activity systems it is charted how both mathematical affordances related to the structure of mathematical concepts and ecological affordances related to socially situated classroom practices need to be considered by teachers in effective mediation of mathematical manipulatives. This paper has three major sections. The first section develops a theoretical extension of Gibson's theory of affordances from natural to social environments. The second section introduces mathematical and ecological affordances using empirical data from a grade two elementary school classroom. The third section illustrates the need of coordinating the two affordances as embedded in different activity systems.

The purpose of this study was to identify environmental perception of eco-friendly apartment residents in the perspective of ecology. Questionnaire survey was adopted in this study, and 92 cases were used for data analysis. As an indicator of environmental perception, the New Ecological Paradigm (NEP) instrument was used. The NEP instrument consists of five dimensions: the reality of limits to growth, anti-anthropocentrism, the fragility of nature's balance, the rejection of exemptionalism, and the possibility of an eco-crisis. The findings showed that the residents held ecological environmental perceptions. Various social characteristics(gender, age, income) of the respondents were related to acceptance of the NEP.

The objective of this study is to propose the whole idealistical process for ecological area zoning based on the natural environment analysis. In order to draw out the ecological zoning, this study used the remote sensing, GIS method and field survey. As a result of this study showed that it was helpful in establishing development direction of Midong Mountain, minimizing the impact on environment by drawing out a development suitable land based on the objective standards and data and also preventing the misconduct development in advance.

Purpose: The study was undertaken to determine the socio-ecological convergence factors affecting on attempts to quit smoking in out-of-school youths. Methods: The study participants were 187 out-of-school youths enrolled Youth support Centers, collected from November 2018 to February 2019, analyzed through x2test and independent sample t-test, logistic regression analysis. Results: There was a significant differences and associated within daily smoking amounts, age of start smoking, intense physical activity, intake breakfast, smoking cessation self-efficiency, and smoking attitude among socio-ecological characteristics according to attempts of quit-smoking. Conclusion: The results of this study will be provided a basic data for developing The Quit-Smoking Intervention Program for out-of-school youth's health activities.

This study analyzed research trends in the field of ecological research. Data were collected based on a keyword search of the SCI, SSCI, and A&HCI databases from January 2002 to September 2022. The seven keywords, including biodiversity, ecology, ecotourism, species, climate change, ecosystem, restoration, wildlife, were recommended by ecological research experts. Word clouds were created for each of the searched keywords, and topic map analysis was performed. Topic map analysis using biodiversity, climate change, ecology, ecosystem, and restoration each generated 10 topics; topic maps analysis using the ecotourism keyword generated 5 topics; and topic map analysis using the wildlife keyword generated 4 topics. Each topic contained six keywords.

Background: South Korea's Act on Registration and Evaluation, etc. of Chemicals (known as K-REACH) was established to protect public health and the environment from hazardous chemicals. 4,4'-Methylenedianiline (MDA), which is used as a major intermediate in industrial polymer production and as a vulcanizing agent in South Korea, is classified as a toxic substance under the K-REACH act. Although MDA poses potential ecological risks due to industrial emissions and hazards to aquatic ecosystems, no ecological risk assessment has been conducted. Objectives: The aim of this study is to assess the ecological risk of MDA by identifying the actual exposure status based on the K-REACH act. Methods: Various toxicity data were collected to establish predicted no effect concentrations (PNECs) for water, sediment, and soil. Using the SimpleBox Korea v2.0 model with domestic release statistical data and EU emission factors, predicted environmental concentrations (PECs) were derived for ten sites, each referring to an MDA-using company. Hazard quotient (HQ) was calculated by ratio of the PECs and PNECs to characterize the ecological risk posed by MDA. To validate the results of modeling-based assessment, concentration of MDA was measured using in-site freshwater samples (two to three samples per site). Results: PNECs for water, sediment, and soil were 0.000525 mg/L, 4.36 mg/kg dw, and 0.1 mg/kg dw, respectively. HQ for surface water and sediment at several company sites exceeded 1 due to modeling data showing markedly high PEC in each environmental compartment. However, in the results of validation using in-site surface water samples, MDA was not detected. Conclusions: Through an ecological risk assessment conducted in accordance with the K-REACH act, the risk level of MDA emitted into the environmental compartments in South Korea was found to be low.
