  • More than half of all the tidal flats and islands in South Korea are located in Jeonnam. Shinangun accounts for a large amount of these tidal flats and island. This study assessed the value of ecosystem services for 14 administrative units (2 'eup' and 12 'myeon') that have around 1,000 islands in Shinangun, using the method described by Costanza et al. (1997). The assessment involved examining the land use types in Shinangun in relation to ecosystem services value. The finding showed that the tidal flat areas had the highest value of ecosystem services in most of the islands of Shinangun, in particular in Aphae-eup and Jido-eup. The study illustrates how quantitative analysis of land use patterns can help local governments like Shinangun to formulate policy for conservation and sustainaable use of ecosystem services. Especially, tidal flat areas are unique and fragile ecosystem, so it is very importat to make strategies for sustainable development in bioculturally diverse areas. Some suggestions regarding landscape planning in Shinangun are provided.

  • The marine ecosystem survey investigates and analyzes multi-parameters at various times from various sites. Therefore, it is very difficult to analyze the complex ecological data of multi-items effectively, and it is more difficult to identify the current status and diagnose the problems of ecosystem through data analysis. Therefore, this paper aims to provide an example of interpretation of complex ecological data through analysis of distribution characteristics and outliers of ecological survey data. The main contents of the study are to elucidate the background levels of coastal ecosystem parameters considering the distribution characteristics of data, and to establish ecosystem monitoring indicators and an adaptive management system for the coastal waters in Korean Peninsula. The data used in this paper are based on the coastal ecosystem survey of the National Marine Ecosystem Monitoring Program conducted by the Ministry of Oceans and Fisheries (MOF) and the Korea Marine Environment Management Corporation (KOEM), and the major citations are from year 2015 to 2017. This article is a preliminary study to establish the above processes and the final result will be derived in 2020 when the coastal ecosystem survey is completed three times along the Korean coast.

  • A facility is built by participating of various parties who are connecting each other by network of contract. Domestic construction industry has been suffering with high cost and low efficiency due to lack of cooperative relationship among companies who participated in the project. The government has tried to resolve this problem by diverse policy support, but practical result has not been realized in the level of satisfaction. This paper defined construction business ecosystem in the aspect of business ecosystem as a network among construction companies based on diverse production system, and diagnosed cooperative business ecosystem in construction industry. For construction business ecosystem to be more cooperative business ecosystem, the result of diagnosis shows that the type of cooperation based capacity and value sharing should be developed and interdependence among companies and cooperative relationship should be durable and reasonable price for construction should be guaranteed for the participant to have a profit from the project.

  • Many countries have established and implemented marine ecosystem management plans to solve various problems arising from excessive development and use of marine and coastal areas. In this study, network analysis was applied to compare and understand marine ecosystem management's direction and characteristics in Korea and other maritime countries. The results showed that the words 'strengthen,' 'promote,' 'improve,' and 'establish' were the keywords used a lot in domestic and foreign marine ecosystem management plans. Establishing a foundation for marine ecosystem management, establishing international cooperation and partnerships, and strengthening climate change adaptation was commonly included. However, there were some differences in detailed management plans. In foreign countries, it aims to present management measures for certain species and improve the existing institutional foundation. Still, in Korea, it aims to strengthen the comprehensive management of marine life and establish an institutional foundation for marine ecosystems. This study is expected to help understand the direction of domestic and overseas marine ecosystem management and establish a domestic marine ecosystem management plan in the future.

  • This study investigated the diversity of butterfly communities inhabiting agroecosystems and examined the effect of latitude and longitude. The ecological characteristics of butterflies inhabiting rural ecosystems, such as habitat preference and food plant range, were also examined. This study was conducted from 2019 to 2022, selecting 10 locations nationwide and conducting line transect surveys every two weeks for four years, confirming a total of 112 species and 21,901 individuals. There was no difference in the number of species and individuals by region, but there was a clear difference in community composition. The most abundant species in rural ecosystems were Pieris rapae, Polygonia c-aureum, Zizeeria maha, and Colias erate, in that order. There was no significant difference in the number of species and individuals by latitude and longitude, indicating no peninsula effect. Habitat preference showed that butterflies preferring grasslands and forest edges were much more common than those preferring the forest interior, and the food breadth was mostly oligophagous, followed by monophagous and polyphagous. Butterflies inhabiting agroecosystems had ecological characteristics that preferred open spaces such as grasslands and forest edges or relatively diverse foods, due to the similarity of the environmental characteristics of the survey points. Through this study, we believe that continuous monitoring is necessary to determine whether climate change, which is currently underway and habitat change are affecting butterflies in agroecosystems.

  • This study established ecological goals and success criteria by using results of the coastal ecosystem restoration demand survey. The ecological goals are set for species diversity, regulation of seawater flow, improvement of purification, erosion prevention and habitat provision by ecosystem types. The indicators of success criteria are chosen the number of emergence species and community characteristics of target organism and pertinent items of hydrologic, water quality and sediment environment by ecological goals among the investigation items of tidal flat investigation guideline.
