The purpose of this study is to seek a planning approach for children's museum within Korean context that promotes community participation. A literature review method and a field survey method were used. Literature reviews on community participation paradigm, residents' participation and donation networks in community regeneration processes, and finally on case studies on children's museum in Korea were carried out. Through the field survey on Chicago Children's Museum(CCM) located in downtown Chicago, its role was identified as networking systems of community participation and donation and was verified as a socio-physical base for vitalizing donation culture that is an active and a leading community participation method. As a result, CCM has engaged many partnerships with city organizations and local schools to provide diverse and unique programs that are not only targeted to children but also parents, teachers and visitors. Also, an evolution of CCM through various types of donations and community participation was delineated. CCM was found successfully in restoring community spirit and vitalizing economical growth where it once was a decayed city area. Rather than focusing on descriptive technique of typical children's museum, this study explored how community fabric is made and acted out, through rethinking community participation's value, and how it can influence a physical space. CCM, as a good example of community participatory museum, the results can be used as a reference in planning and directing community participation based children's museums in Korea. It is significant to shed light on children's museum as an opportunity of social space which can empower community.

The Seoul Woods Design Competition in 2003 was one of the most remarkable events within the field of landscape architecture in Korea since the Yeo-Ui Do Square Park Design Competition in the mid 1990s. This study examines the overall procedure, evaluations and competition guidelines for the Seoul Forest Park Design Competition and identifies the implications and issues related to Korean landscape architecture. In addition this study analyzes the design concepts, strategies and spatial composition, and programs of five selected design worts including the best awarded work. This study also examines key features and issues from the five selected design works. Finally, this study examines a new trend of landscape design in Korea, which can be observed at the Seoul Forest Park Design Competition. In this study, it is argued that the Seoul Forest Park Design Competition had significant implications for landscape architecture in Korea. Firstly, the Seoul Forest Park Design Competition was the greatest project in Korea in terms of its size. Therefore, it shows us an enhanced status of Korean landscape architecture. Secondly, the Seoul Forest Park Design Competition provided a good opportunity to redefine the concept of 'park' in Korean modern society. Thirdly, through the Seoul Forest Park Design Competition, we can observe a dramatic change and developments in Korean landscape design since the 1990s, as well as the present status of landscape design competitions in Korea. And this study identifies an emphasis of a program in design, an evolution in ecological approach an diminishment in concern of Korean tradition, and a change in design methods and media, which are some aspects of Korean contemporary landscape design observed at the Seoul Forest Park Design Competition.

Lepomis macrochirus from the family Centrarchidae, commonly known as Bluegill sunfish, is an introduced freshwater fish in Korea that thrives in lakes, ponds, reservoirs and rivers. Since its introduction into Korea in 1969, Lepomis macrochirus has rapidly dispersed out and increased in number almost all over the freshwater ecosystems in Korea. Consequently this species causes a severe ecological problem, threatening native fishes due to its omnivorous foraging behaviors upon fish juveniles and many freshwater invertebrates. To address population genetic structure of L. macrochirus, 74 fish samples from 10 populations were collected and compared for their mitochondrial D-loop control region. As the result we found that the genetic diversity of L. macrochirus is extremely low such as resulting only four haplotypes with a few nucleotide differences among them. Analysis of molecular variance (AMOVA) revealed that the source of population genetic variation is largely retained in the comparisons among individuals within populations, while it is relatively low with slight significance at the highest hierarchical group. This distribution pattern differs from what is expected when biogeography is under the influence of natural geographic barriers such as mountain ranges in Korea. Instead the result is accord with the influential role of random spreading events facilitated by local people for aquaculture and fishing, and subsequent dispersals since its single point of introduction into Korea.

The Songji lagoon is brackish environment with a mixture of saline and fresh water, and the interaction of groundwater-lagoon water creates a physicochemical gradient. Although some studies have been conducted on the hydrological and geochemical characteristics of the Songji lagoon, microbial ecological studies have not yet been conducted. In this study, we investigated the effect of groundwater and surface water interaction on water quality as well as microbial community changes in the Songji Lagoon using 16S rRNA gene sequencing. Hydrochemical analyses show that samples were classified as 5 hydrochemical facies (HF) and hydrochemical facies evolution (HFE) revealed the intrusion phase was more dominant (57.9%) than the freshening phase (42.1%). Higher microbial diversity was found in freshwater in comparison to saline water samples. The microbial community at the phylum level shows the most dominance of Proteobacteria with an average of 37.3%, followed by Bacteroidota, Actinobacteria, and Patescibacteria. Heat map analyses of the top 18 genera showed that samples were clustered into 5 groups based on type, and Pseudoalteromonas could be used potential indicator for seawater intrusion.

Background: Despite many environmental problems, plastic waste emissions have been a significant surge during last few decades in the Republic of Korea. Furthermore, the emergence of the coronavirus disease 2019 (COVID-19) pandemic has lead to an increased use and disposal of plastic waste worldwide. This paper tried to present summarized data related to the production and disposal of plastics especially before and after the COVID-19 pandemic with environmental impacts of plastics. Also, review of plastic waste reduction policies and feasible policies to promote an act for a safe, sustainable environment are presented. Results: Plastics cause many environmental problems due to their non-degrading properties and have a huge direct and indirect impact on Ecosystems and Public Health. Microplastics need a lot of attention because their environmental effects are not yet fully identified. Despite plastic's significant impact on climate change, the impact is not yet widely known to the public. Since the COVID-19 pandemic, the use of plastic has surged and recycling has decreased due to the increase in delivery food and online shopping. Korea is introducing very active plastic and waste management policies, but it is necessary to implement more active policies by referring to the cases of other countries. Conclusions: In this article, we have scrutinized the evolution of plastic waste generation in the aftermath of the COVID-19 pandemic and delved into policy frameworks adopted by other nations, which South Korea can draw valuable lessons from. The formidable challenges posed by plastic waste, the remarkable shifts witnessed during the COVID-19 era, and the multifaceted response strategies elucidated in this paper all play a pivotal role in steering South Korea toward a sustainable future.

The aim of this study was to propose methods to transplant for the ecosystem damage borrow pits. The research site is Junggun-dong Gwangyang-si Jeollanam-do. The total area of the site is approximately $199,026m^2$, but the area damaged by exploitation of soil and rocks is about $84,200m^2$. This signals the transplanting method to solve the problems of ecological destruction. The research will focus on the areas either which are evaluated as damaged or in which the development is inevitable. Therefore, this study will investigate the vegetation structure and their evolution, topological and soil character, and annual ring structure; in the end, the study will propose compensating and restoring options. This study proposed the selection of trees and their planting methods by using the models of the community transplantation(Quercus mongolica trees) and the tree transplantation(Pinus thunbergii trees). The study set out plans that will attempt to restore the Quercus mongolica forests and 89 Quercus mongolica trees of the canopy layer trees, 153 middle layer trees, and 661 shrubs are suitable. The tree transplantation utilized the existing Pinus thunbergii trees. The number of transplantation is 2,648. The total area of the transplantation topsoil is calculated to be $15,353m^3$. These study results must be contributed to reduce a damaged ecosystems and compensated damaged ecosystems for solving the problem of damaged borrow pits.

The tiger population that once inhabited the Korean peninsula was initially considered a unique subspecies (Panthera tigris coreensis), distinct from the Amur tiger of the Russian Far East (P. t. altaica). However, in the following decades, the population of P. t. coreensis was classified as P. t. altaica and hence forth the two populations have been considered the same subspecies. From an ecological point of view, the classification of the Korean tiger population as P. t. altaica is a plausible conclusion. Historically, there were no major dispersal barriers between the Korean peninsula and the habitat of Amur tigers in Far Eastern Russia and northeastern China that might prevent gene flow, especially for a large carnivore with long-distance dispersal abilities. However, there has yet to be a genetic study to confirm the subspecific status of the Korean tiger. Bone samples from four tigers originally caught in the Korean peninsula were collected from two museums in Japan and the United States. Eight mitochondrial gene fragments were sequenced and compared to previously published tiger subspecies' mtDNA sequences to assess the phylogenetic relationship of the Korean tiger. Three individuals shared an identical haplotype with the Amur tigers. One specimen grouped with Malayan tigers, perhaps due to misidentification or mislabeling of the sample. Our results support the conclusion that the Korean tiger should be classified as P. t. altaica, which has important implications for the conservation and reintroduction of Korean tigers.

The paper describes the history and the evolution of the conflict of the Saemangeum reclamation project, focusing on the court trial processes. The Saemangeum project is the world largest coastal reclamation work, regarded as the most controversial environmental issue in the recent history of Korea. Due to the severe pollution found in Lake Sihwa in 1996, the Saemangeum project began to receive a large degree of public concern on the water quality of the proposed artificial freshwater lake. Unlike the Sihwa case, the Korean court system intervened to resolve the heated conflicts between stakeholders in the Saemangeum case. Based on the same set of facts, the Korean courts showed different perspectives on the economic feasibility, value of the ecosystem, land use, and water quality, which represents the limit of legal system to address complicated environmental problems. After the final judgment by the Supreme Court, 'the Special Act for the promotion of the Saemangeum reclamation project', was enacted with strong political support from local leaders and congressmen. A more developmental-oriented land use plan came out in 2009 based on this Act. The Saemangeum project walked along the different pathway from the Sihwa case. The area should be managed in sustainable manners to appropriately consider conservation and development for the prosperity of local residents and future generations.

The cultural contents are a field that originally has a cycle ranged from producers of various contents and distribution consumption. The various object elements composing of an ecosystem of cultural contents in this cycle, and the search of harmonious relations between these objects is becoming an important issue. The ecological approach on the cultural contents field is not being tried authentically until now, in spite of the expansion of interest and usefulness from its application at present, so there is no detailed discussion on the inside of an ecosystem and itsaction such as confirmation of object elements composing of the ecosystem, interaction principles between objects and object development, principles of co-evolution, etc. achieving common development of all objects composing of the ecosystem. Therefore, the present research aims to confirm object elements composing of the ecosystem of cultural contents through an ecosystem model that has been researched in several fields of the ecosystem and social science, and to seek interaction between objects and each object as well as a development direction of a total ecosystem.

The pollen dispersal by wind can make an important to understanding the viability and evolution of plants in ecological and agricultural science. Modelling can be applied to evaluate concerns about the spread of engineered pollens from genetically modified (GM) crops. Here, we are using gamma model to estimate the level of dispersal distance of pollen in the cross-pollination between two different maize (Zea mays L.) cultivars in GMO field of Korea University during the year 2010. The result of estimation of model indicates maximum pollen dispersal distance of estimated proportion of cross-pollination of maize was reached to 0.1% in 525 meter northwest due to the wind. We identify further measurements necessary to improve the accuracy of the model predictions.
