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 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.

새만금 간척사업의 역사와 갈등을 소개하고 행정소송과정을 서술하였다. 세계 최대의 간척공사인 새만금 간척사업은 한국에서 가장 갈등이 심한 환경이슈로 여겨진다. 1996년에 발생한 시화호 오염사건을 계기로 새만금 사업의 인공 담수호수 수질문제가 사회적인 관심사와 이해당사자의 갈등을 불러일으켰다. 이를 해결하기 위해 사법재판부가 개입한 것이 시화호와 다른 새만금 사업의 특징이다. 1, 2차 재판부가 동일한 사실에 대해서 경제적 타당성, 생태계 가치, 토지이용, 수질에 대한 상이한 판결을 내린 것은 복잡한 환경문제를 다루는데 있어 법률적 제도의 한계점을 보여준다. 대법원의 최종판결 직후 지역주민과 국회의원의 강력한 지지에 힘입어 새만금 사업촉진을 위한 특별법이 제정되었다. 2009년에는 이 법에 근거한 새로운 토지이용 계획이 수립되었다. 새만금 사업은 시화호와는 전혀 다른 진행과정을 보여주고 있다. 새만금 지역은 개발과 보존이 조화를 이루며 지역주민과 미래세대의 번영을 위한 지속가능한 방법으로 관리되어야 한다.

최근에 와서 전시회는 다양한 유용성으로 인해 질적 양적 성장을 거듭해오고 있는 분야로서 여러 측면에서 활발한 연구가 진행되고 있는 분야이다. 특히 그동안 전시회 연구는 서비스 품질만족, 관람 동기, 기업의 성과 획득 등의 분야에서 집중적인 연구가 실시되고 있다. 하지만 이와 같은 연구는 전시장의 시설과 규모 등 전시장 품질의 동질화 및 일반적인 운영 노하우의 증진에 따라 전시회별 차별점을 찾기에 힘든 부분이 되고 있다. 이런 상황에서 전시회 기획에 있어 전시회를 구성하는 콘텐츠에 대한 중요성이 더욱 강조되고 있다. 본 연구는 2010년 4월 29일부터 5월 9일 까지 부산 벡스코에서 전개됐던 2010 부산국제모터쇼의 방문객들을 대상으로 전시회를 구성하는 콘텐츠별 관객 만족도 및 콘텐츠 유형에 따른 재방문 의사와 추천의사의 확인을 통해 전시회의 효과를 확인하고자 시도되었다. 연구결과 관람콘텐츠와 전시 콘텐츠 등의 만족이 높았으나 재방문 및 추천의사가 높았던 콘텐츠의 유형은 공연, 전시, 참여콘텐츠 등이 였으며 이는 곧 관람자들이 전시회를 단순히 해당 전시품의 관람만이 아니라 마치 축제와 같은 복합적인 공간으로 인식하고 있다는 것을 의미한다고 할 수 있다. 따라서 향후 전시 기획에 있어 콘텐츠의 종류(what to do)는 콘텐츠의 전개(how to do)와 함께 보다 관심하게 준비되어야 할 것이며 이는 곧 관람객의 관점에서 볼 때 전시회는 비즈니스 공간만이 아닌 엔터테인먼트를 위한 시간과 공간이라고 할 수도 있기 때문이다.
