The needs for ecological engineering, which can design ecosystems that integrate human society and their natural environment for the benefit of both, has increased. The Korean Society of Ecology and Infrastructure Engineering (KSEIE) was established for this purpose and has contributed to the research and development of theories and technologies in related fields. However, the current state of educational services and contents of ecological engineering is still needed to be standardized and systematized. In this paper, we outlined the trends of ecological engineering education at international and domestic levels and proposed a sample services and curriculum, brought from the discussions and suggestions made during the forum, Founding the Education for Ecological Engineering, held by the KSEIE. Education of ecological engineering can nurture people who can design and manage ecosystems for the benefits of human and natural society and can restore ecosystems disturbed artificially. The services and curriculum have to meet and cover the challenges facing the future of ecological engineering; a. the ethical interpretation of the balance between human and nature, b. developing and strengthening its relationship with other scientific disciplines and societies - business, policy, education, and practitioners, c. identify and fuse the key ecological engineering principles into other discipline. We proposed a three layers curriculum system, basic (mathematics, physics, chemistry, biology, etc.), core (ecology, hydrology, engineering, etc.), and advanced subjects. The first two can belong to an undergraduate program and the last two can be put into graduate program. The selection of subjects is according to the purpose and needs of the major.

Social demand for ecological engineering and technology has increased in tandem with national economic growth in order to improve the environmental capacity of civil infrastructures. To meet this demand, the Korean Society of Ecology and Infrastructure Engineering (KSEIE) was established in January 2013 and has contributed to the development of ecological engineering technologies. However, the establishment of an educational system for human resources training in ecological engineering is still at an early stage, and it is imperative to develop a curriculum for producing the human resources that can understand and apply ecological principles and functions and that is equipped with the abilities required for ecological conservation, restoration, and creation. As part effort, the KSEIE held a forum, entitled Founding the Education for Ecological Engineering, to discuss the establishment of the education system for ecological engineering in Korea. In this paper, based on the discussions and suggestions made during the forum, we analyzed the current status of ecological engineering education in various disciplines - civil and construction engineering, biology and environment, and landscape planning - in domestic universities, and attempted to seek possible solutions based on the cases of foreign universities. Generally, ecology and other application curricula are taught as fragmented subjects and fields in domestic universities. The development of new education strategies and systematic curricula for multidisciplinary education, ecological response to climate change, and the expansion of research fields is required.

This study investigated the difference in fish community structures in a main channel and an isolated former channel, considering the environmental factors in the Mangyeong River, Korea. Principal component analysis (PCA) with environmental factors showed that former channels were composed of a fine substrate covered by in-stream vegetation, whereas the main channel was covered by a wide range of substrates with a higher dissolved oxygen and conductivity. The result of the hierarchical cluster analysis with species abundance delineated to the four main groups; three abandoned channel groups and one main channel group. Non-metric multidimensional scaling (NMDS) showed that fish community structures of each study site differed from environmental factors: former channel fish communities were positively related to in-stream vegetation cover, whereas main channel fish communities were positively associated with dissolved oxygen and conductivity. The results indicated that channelization, where there was a separation between the former channel and the main channel, had detrimental effects on fish community structures of both the main channel and the abandoned channel in the Mangyeong River. In conclusion, this study suggested that the connectivity between the main channel and abandoned channel were required to enhance both habitat structural diversity and species diversity of the Mangyeong River.

In this study, an optimal improvement method of stream channel structure is presented for the enhancement of fish habitat suitability by genetic algorithm. The correlation between fish habitat suitability and physical disturbance in stream is analyzed according to the changes of hydraulic characteristics by channel structure rehabilitation. Zacco koreanus which is an indicator fish of the soundness of aquatic ecosystem was selected as a restoration target species by investigating the community characteristics of fish fauna and river environments in Wonju stream. The habitat suitability is investigated by PHABSIM with the habitat suitability index of Zacco koreanus. Hydraulic analysis by HEC-RAS and physical disturbance evaluation in stream are carried out. The optimal channel width modified for the enhancement of fish habitat suitability is provided. The correlation analysis between habitat suitability and physical disturbance with the change of hydraulic characteristics by channel modification showed that the proper channel modification enhanced fish habitat suitability and mitigated physical disturbance in the stream. The improvement of physical disturbance score by the channel structure rehabilitation for the enhancement of fish habitat suitability was confirmed in this study.

In order to assess the hydraulic effects of flow pattern changes and geomorphological evolution around spur dikes, this study carried out monitoring and numerical simulation on the changes of morphologic characteristics around spur dikes that settled in the bend of the Yeongcheon River. The study site spanned 190 m, and spur dikes were installed in March 2008. Monitoring of the site started in May 2008 and was completed in April 2014. When the water level was higher than the height of the spur dikes, the spur dikes extrude flow from the bank. Therefore, the spur dikes that were built to stabilize the channel have been effectively performing hydraulic functions. With the passing of time, the channel was stabilized and pools formed around the spur dike toes by local scouring. It was confirmed that spur dikes created various physical characteristics in the aspect of channel topography, with sediments deposits occurring between the spur dikes, while riffles and pools formed in the channel.

This study was conducted to investigate the flora and vegetation structure at a 15-year-old artificial wetland for the water purification in Jincheon, Korea. The percentage of species number of obligate wetland plants and facultative wetland plants totaled 40%, whereas that of obligate upland plants and facultative upland plants was 57%. This result showed that the artificial wetland in the study experienced terrestrialization. The number of annual and biennial plants that are pioneer vegetation in a successional stage was lower than that of perennial herbs as a result of the long-term stabilization of vegetation. From the results of DCA (detrended correspondence analysis), water depth played an important role on the classification of vegetation structure in an old artificial wetland. Species diversity was higher in the terrestrialized plant communities such as Iris pseudacorus and Aster koraiensis than in any other wetland communities. Plant communities could be classified according to the wetland indices; obligate upland for A. koraiensis community, facultative wetlands for Carex dispalata var. dispalata and I. pseudacorus community, and obligate wetlands for Nymphoides peltata, Nymphaea tetragona, Phragmites communis, Potamogeton maackianus, and Typha angustifolia community. In conclusion, this result suggests that wetland vegetation should be maintained against terrestrialization through the proper management of sedimentation and hydrological regime in an artificial wetland.

We investigated the tidal current, hydrographic data, and benthic environment of major sea cucumber (Holothuroidea, de Blainville, 1834) habitats in Baengnyeongdo, Jindo and Uljin to understand the optimal environmental or ecological habitat for sea cucumbers. The three study areas were characterized by a cold-water mass of temperatures ranging
, with an active circulation between the surface and deep waters. According to an analysis of the tidal current map, a strong flow velocity of
appeared in Baengnyeongdo and Jindo. The three sea cucumber habitats showed the common characters of a bottom sediment composed of sand-silt, a diverse seaweed colony and benthic organisms, and boulders and rocks which provide a hideout for the organisms. We aimed to draw the optimal habitat condition for sea cucumbers in Korea, and the result showed that the low water temperature, rapid water flow, active vertical mixing between surface and deep waters, bottom composed by sand-silt, large rocks, and diverse seaweed colony and benthic organism were important factors. The optimal habitat for Juvenile sea cucumbers was the intertidal areas characterized by a muddy bottom, reef, and seaweed. The optimal habitat for adult sea cucumbers was characterized by a place where sand and mud are mixed, and the body size of the sea cucumber was proportional to water depth, and the relatively large boulders and rocks compared to the intertidal area.

Some of alien plants, which were introduced from foreign countries, have caused problems in Korea. Invasion of these alien plants in the ecosystem threatens the habitat of endemic species, reducing biodiversity, and causing a disturbance in the ecological system. In urbanized areas of campus universities, a diverse range of organisms were found and a comparison between the sites, near roads or housing sites were made because the campuses provided a large biotope. Although the campus had been exposed to interferences like gardening, it was also a place for most organisms to live in an active floating population due to free access. This research investigated the flora of alien plants that appeared in Beakseok University, Sangmyung University, Hoseo University and Dankook University, and relationship between the distribution of alien plants and the campus and green areas and distance from the highway. The total number of plant species and naturalized species found in the four universities was 189 and 43 species. Those of Dankook University were 136 and 35 species, Hoseo 108 and 25 species, Sangmyung 103 and 31 species, and Baekseok 97 and 26 species, respectively. The abundance of natural plants for each respective university tended to be higher as it became closer to the highway. Also, the closer the walking distance to the university, the greater the tendency for the degree of similarity to be higher. As a result, we may conclude that the distribution of alien plants and anthropogenic activities may be closely related.

Acid mine drainage (AMD) producing mine tailings can be beneficially recycled to generate electricity by applying fuel cell technology. Pyrite-containing mine tailings and indigenous bacteria from abandoned mine areas were used to construct fuel cells to investigate the effect of pyrite contents and the presence of iron-oxidizing bacteria. The results showed an enhanced electrical performance with a higher content of pyrite in mine tailings. The inoculation of the indigenous bacteria also enhanced the current density by about three times, and the power density by about 10 times. Overall, this study shows that the combined use of the ecological function of indigenous bacteria from mine areas and mine-tailings in fuel cells does not only contribute to reducing harmful effects of mine tailings but also generate electricity.

Topsoil including numerous soil seedbanks has been known to be a valuable material for ecological restoration. There is a lack of specific study for its utilization in the field of stream restoration. This study conducted a revaluation of the value of topsoil as a material for stream restoration. Furthermore, an ecological technique using topsoil was applied in an improvement project of a stream environment at the Hwanggujicheon Stream in Korea. Stockpiling and spreading topsoil was specifically applied to the revegetation of a low slope revetment and a high flow plain. The result of this application showed that topsoil played an integral role in eco-friendly restoration in terms of ecological, flood control, economic, and constructional aspects. In conclusion, this study`s findings suggest that topsoil is a suitable candidate material for stream restoration.
