Riparian areas are significant functional grounds for inhabiting ecological system on the river such as the self-regulation of the water quality and the foundation of important corridors. For such functional device to operate, consecutive land purchase scheme that prioritizes targeted areas with high pollutant load rate imposes sustainable development of the ecological riparian belt. The purpose of this study is focused on measuring the methodology for selecting land purchse order before establishing riparian belt in accordance with pollution loading estimation and the basin approach. The Yeongsan and Seomjin river which includes targeted areas of the land purchase have been classified into the large-medium-small(standard basin) influence areas based on their catchment rage, which than sub-divided the research area of Juam lake by 38 small basins and 223 units. Small basins with the high pollution load rates have been assessed as the first prioritized targets. For the second priority, the condition of the point pollutant sources, original area of the targets, original restored area were concerned. The final decision of the land purchase order targeted only those within 50 meter range from the basin. To validate the accumulated data, the on-site investigation went along the targeted zones, which the result shows that all prioritized areas included both point and non-point pollutant sources, and had not a small originally restored areas.

Purpose: This study tries to systematically understand factors that explain levels of happiness among pregnant women in the Ecological systems theory. Methods: A descriptive, cross-sectional study was conducted with 169 pregnant women in Korea. Collected data from self-report questionnaires were analyzed by hierarchical regression analysis using the SPSS statistics 23 program. Results: A total of 5 models were examined according to individual, microsystem, mesosystem, exosystem, and macrosystem in the Ecological systems theory. In the first model including individual factors, extraversion, neuroticism, and physical and psychological change constitute significant factors explaining happiness. In the second model with microsystem factors and in the third one with mesosystem factors, marital intimacy appears to be a significant factor. In the fourth model including exosystem factors, community service is a significant factor. In the final model with social atmosphere, personality (${\beta}=.15$ for extraversion; ${\beta}=-.30$ for neuroticism), physical and psychological change (${\beta}=-.15$), marital intimacy (${\beta}=.35$), and community service (${\beta}=.18$) turn out to be significant. These factors explain 59% of the variance of happiness in the pregnant women in Korea. Conclusion: Considering the fact that pregnant women's happiness is explained by microsystem and exosystem factors as well as individual factors, developing intervention programs that can promote influencing factors such as marital intimacy and community service is necessary to improve levels of happiness among pregnant women in Korea.

The purpose of this study is to investigate a student's career maturity during a career exploration program based on the ecological system perspective and to propose directions for the career maturation process to help H. Meister High School students to get jobs. A single-case 12-session career exploration program was applied to a first-year student at H. Meister High School in U. City for 90 minutes per session twice a week. To verify the effects of the program, this study conducted a pre-test and post-test of career maturity to analyze changes. In addition, the study qualitatively analyzed changes in the program activity sheets and process evaluation sheets per session. The results of the study are as follows: Firstly, the career exploration program based on the ecological system perspective conducted with the student at H. Meister High School improved the student's career maturity. Secondly, changes were observed in the scores in the sub-factors of career maturity between the pre-test and the post-test. Significant differences in the results of the analysis of the sub-factors of career maturity indicate that the program had a statistically positive impact on the career maturation process of the participant. In conclusion, as a result of the in-depth implementation of the program for 12 sessions, the participant expressed his desires which were clarified. In addition, a positive career maturation process appears to have taken place, owing to the self-directed program that led the participant to initiate plans and explore his career by himself. This study was conducted as a single case based on the ecological system perspective concerning career exploration and the career maturation process, but it will be necessary to expand the study to investigate the effects of group counseling, information exchange considering peer influences, common discussions on goal-setting, and other methods on the career maturation process.

This study attempted an eco-ethical approach to the sporting body, focusing on Toegye's Gyeong. A causes for the conflict between man and nature is a wrong view of nature derived from human desire. Toegye thought that the problem of desire could be overcome through Gyeong. Eco-ethical approaches of Toegye's gyeong thought are possible for the following reasons: First, because Toegye's gyeong is completed in nature. Second, because Toegye's gyeong emphasize human responsibility (consideration) for nature. Third, because gyeong is related to the ability to practice morality. Meanwhile, Toegye understood 'preserving the body well' as self-preservation and at the same time, as the meaning of a natural principle of following the laws of nature. From this perspective, the sporting body has meanings of physical fitness and mental health and at the same time, an aspect of ecological values of understanding man and nature as a single network and following the order of nature. Acquisition of Gyeong through the sporting body suggests the practice of 'gyeongsin (respect for the body)' and 'hwalgyeong (preservation of the ecological environment).' When human beings do physical exercise with nature, they proceed to the stage of building up the virtue of yosan yosu (finding happiness in mountains and water) through nature preserving the ecological environment (hwalgyeong) beyond staying at the stage of gyeongsin.

This study explores Witi Ihimaera's The Whale Rider (1987) from ecological and postcolonial perspectives. Ihimaera is one of the prominent Maori writers who have critically voiced their concerns about the fragmentation of Maori tradition and the alienation of an environmentally friendly culture in New Zealand. Throughout the novel The Whale Rider, with his mythic imagination and cultural sensitivity, Ihimaera raises ecological awareness in terms of environmental justice and promotes critical consciousness regarding sociocultural and histo-political realities of the Maori people as alienated others in their ancestors' land. Revolving around the developmental process of a young Maori girl named after a mythical Maori ancestor Kahutia Te Rangi also known as the Whale Rider to inherit the Maori leadership, the novel describes the historical, cultural, emotional landscape of the Maori community in the white-centered society of New Zealand. In particular, this paper analyzes the leaving and homing process of narrator Rawiri which is deeply embedded in Maori myth and philosophy toward an eco-friendly culture and postcolonial reality. Indeed, Ihimaera skillfully juxtaposes young man Rawiri's experience outside the Maori community and young girl Kahu's life at the Maori home. In the end, while Kahu achieves her destiny in a mythical way to foster a new vision of harmonious co-existence that is rooted in Maori heritage and compatible with Western culture, Rawiri comes to understand the interrelatedness of all existence and embraces both the rational knowledge of scientific empiricism and the traditional knowledge of spiritual experiences. The novel The Whale Rider was also turned into a film by New Zealand's most influential female film director Niki Caro in 2002, and the film Whale Rider received international acclaim.

Objectives: Residents of a single room occupancy (Jjok-bang) in Seoul are at high risk of having mental health issues. The majority of residents live in single households with past traumatic experiences including self-deprivation and social exclusion. This study was to investigate the association between mental health and socio-ecological factors at the intrapersonal and community levels. Methods: We conducted face-to-face surveys in Dongja-dong Jjok-bang area in June, 2014. Of 78 participants, 76% were male and the mean age was 60 years (SD=11.53). A multiple regression was used to analyze the association among depression, a sense of well-being, socio-ecological factors, and perceived empowerment and community solidarity. Results: Perceived empowerment (${\beta}=0.83$; 95% CI=0.40, 1.26) and community solidarity (${\beta}=0.52$; 95% CI=0.04, 1.01) were positively associated with a sense of well-being. Participants with empowerment (${\beta}=-2.55$; 95% CI=-4.86, -0.23) and those with community solidarity (${\beta}=-2.36$; 95% CI=-4.94, 0.21) were negatively associated with being depressed. Conclusion: Mental health of the residents in Jjok-bang was more influenced by empowerment and community solidarity than socio-demographic factors. It is necessary to improve public health infrastructures that can enable the residents to enhance empowerment and community solidarity utilizing socio-ecological perspectives.

Changpo Lake was created as a part of a land reclamation for refugee self-helping projects. It shows characteristics of a fresh water lake, and still retains the early appearance of reclamation that surrounding regions have not been developed into farm lands. Shallow wetland has formed around the lake, which provides great conditions for diverse lives, and surrounding earthiness is favorable for growth of vegetation and restoration of the ecosystem. However, as facilities of the Muan International Airport nearby Changpo Lake are expanding and barns are being constructed, artificialness is gradually increasing. Particularly, since pollution sources such as sport facilities, farm lands and barns are scattered around Changpo Lake, pollutants are flowing in constantly. Accordingly, the results for setting up management areas according to the spatial characteristics and creating natural ecological spaces near Changpo Lake, Taebongcheon stream and Hakgyecheon stream are as follows. First, the creation of a natural eco-friendly waterfront space should be promoted by securing the health of the aquatic ecosystem and restoring species and the ecosystem. In addition, a consultative body needs to be formed to lead local residents to participating in river investigation and monitoring, maintenance, and management through role sharing. Second, the basic direction of the spatial management plan is to keep the unique charm of Changpo Lake, maintain harmony with nature, create diverse waterfront areas, and secure the continuity of Changpo Lake and inflow streams. Moreover, the area should be divided into three zones such as a conservation zone, a restoration zone and a waterfront zone, and for each zone, the preservation of vegetation, the creation of ecological wetlands and restoration of the ecotone and ecological nature need to be promoted. Third, facilities and activity programs for each space of Changpo Lake should be operated for efficient management of protected areas. In order to suit the status of each space, biological habitats, water purification spaces, experiential and learning spaces, and convenience and rest spaces should be organized and designated as research, monitoring, education, and tourism areas. Accordingly, points of interest should be set up within the corresponding area. In this study, there are many parts that need to be supplemented for immediate implementation since the detailed plans and project costs for the promotion of programs by area are not calculated. Therefore, it is necessary to make detailed project plans and consider related projects such as water quality, restoration of habitats, nature learning and observation, and experience of ecological environments based on the categories such as research, monitoring, education and tourism in the future.

The alkaliphilic, calcium carbonate precipitating Bacillus sp. strain AK13 can be utilized in concrete for self-repairing. A statistical experimental design was used to develop an economical medium for its mass cultivation and sporulation. Two types of screening experiment were first conducted to identify substrates that promote the growth of the AK13 strain: the first followed a one-factor-at-a-time factorial design and the second a two-level full factorial design. Based on these screening experiments, barley malt powder and mixed grain powder were identified as the substrates that most effectively promoted the growth of the AK13 strain from a range of 21 agricultural products and by-products. A quadratic statistical model was then constructed using a central composite design and the concentration of the two substrates was optimized. The estimated growth and sporulation of Bacillus sp. strain AK13 in the proposed medium were 3.08 ± 0.38 × 10⁸ and 1.25 ± 0.12 × 10⁸ CFU/ml, respectively, which meant that the proposed low-cost medium was approximately 45 times more effective than the commercial medium in terms of the number of cultivatable bacteria per unit price. The spores were then powdered via a spray-drying process to produce a spore powder with a spore count of 2.0 ± 0.7 × 10⁹ CFU/g. The AK13 spore powder was mixed with cement paste, yeast extract, calcium lactate, and water. The yeast extract and calcium lactate generated the highest CFU/ml for AK13 at a 0.4:0.4 ratio compared to 0.4:0.25 (the original ratio of the B4 medium) and 0.4:0.8. Twenty-eight days after the spores were mixed into the mortar, the number of vegetative cells and spores of the AK13 strain had reached 10⁶ CFU/g within the mortar. Cracks in the mortar under 0.29 mm were healed in 14 days. Calcium carbonate precipitation was observed on the crack surface. The mortar containing the spore powder was thus concluded to be effective in terms of healing micro-cracks.
