Recently mobile service industry has grown very rapidly. In this paper, I investigated the changes in mobile service industry as well as new direction of human life in future global society. Under these changing market conditions, competition has been also changed into global and ecological competition. But compared to the platform initiatives and ecological strategies of global companies, Korean companies' vision of building ecosystems is still unclear. New directions of mobile service industry are smart phone oriented open market, UCC, QPS and cloud computing. As such, I investigate the structure of mobile service ecosystem in order to gain strategic implications and insights in this paper.

Industrialization and modernization of the $20^{th}$ century have brought convenience to human life. However, such development produced unintentional global environmental issues such as destruction of natural ecosystem through excessive use of the natural environment beyond its capacity. The United National (UN) recognized such global environment issues and coordinated with worldwide experts to conduct a comprehensive assessment of the global ecosystem, "Millennium Ecosystem Assessment (MA)", to resolve the issues. The UN conducted the MA primarily to comprehend the correlation between the ecosystem and human welfare. The results demonstrated that the ecosystem provides various direct and indirect benefits to human. This new concept was introduced as the "ecosystem services". Introduction of the ecosystem services highlighted the significance of the ecosystem and led to increased research and active discussions among experts from various discipline over the recent 10 years. It has been considered that the ecosystem service concept could be incorporated in policymaking process, as primary criteria to assess and weigh the benefits of using natural resources against the effects on value of the ecosystem. The current policymaking process is affected by the contradicting logics of modernization and preservation of ecosystem. The ecosystem services concept could be the answer to forming a rational policymaking process, allowing for nature preservation while wisely using the available natural resources. The general consensus has been formed on the need of incorporating the ecosystem services concept in the policies and globally various researches on the ecosystem services have been actively conducted. However, introduction of the ecosystem services concept is still at a very early stage and research on real application of the ecosystem services is yet almost nonexistent. Also there are no clear and agreed definition, classification scheme and value appraisal methodology regarding the ecosystem services. Therefore, this research explains the basic concept of the ecosystem services and highlights specific issues for further researches, as further researches on real application of the ecosystem services would find ways for the ecosystem services approach to be valuable in the policymaking process.

A human in urban areas has depended on ecosystem for well-being, so it is important to evaluate urban ecosystem services which contribute significantly to human well-being. In this study we classified ecosystem functions and set indicators used for evaluating ecosystem services of urban park by Delphi method. As a result, it derived 12 items and 14 indicators of ecosystem services to evaluate them such as vegetable garden, canopy cover, biodiversity, and educational programs. Based on the derived evaluation indicators, the feasibility of the indicators was examined by applying to two urban parks, Maetan park and Seoho-Ggotme park, in Suwon City. We also suggested strategies to improve each ecosystem services based on the results of evaluation. It is significant to recognize unknown services in urban parks. The results can be used for improving urban ecosystem services consistently in response to current rapid urbanization. In the future, the city should make a master plan on ecosystem service on urban area, beyond urban park, considering both of quality and quantity.

Based on 3-period land use data using RS and GIS, this paper analyzed landuse change and subsequent loss of ecosystem service value, using the ecosystem service value coefficients put forward by Costanza. Results show that from 1917 to 2006, area of crop land, plantation, building site, unused land increased and natural forest, grassland, water area, wetland decreased, in Musan region and Hoeryeung region. But the area of natural forest is acute reduced by 7,925.34ha and the amplitude of building site is increased rapidly in Musan region. The area of grass land is acute reduced by 71,594.34ha and the amplitude of unused land is increased rapidly in Hoeryeung region. Total ecosystem services value of Musan region reduced dramatically, from $66,135.26{\times}10^6$ won to $37,894.51{\times}10^6$ won in period 1917~2006. The net decreased ecosystem services value is $28,240.75{\times}10^6$ won and the increased amplitude is 42.71% in Musan region. Total ecosystem services value of Hoeryeung region reduced dramatically, from $145,862.69{\times}10^6$ won to $106,948.44{\times}10^6$ won in period 1917~2006. The net decreased ecosystem services value is $38,914.25{\times}10^6$ won and the increased amplitude is 26.68% in Hoeryeung region. Therefore, the effective measures should be taken to maintain sustainable development of environment.

This study was conducted to suggest an assessment indices to evaluate the ecosystem services of the unique functions of wetlands as well as economic value provided by the village wetlands. The assessment indicators applied in this study were used by the RAM indices. The results of RAM assessment on the village wetlands in Cheonan city were analyzed by item and critical functions of the village wetland. They were derived by assessment indicators of ecosystem services, and the village wetland ecosystem were presented by Focus Group Interview (FGI). The 20 critical indices were selected from 52 different indices by analyzing the wetland function assessment items. 13 indicators excluding duplicate indexes by function, were selected as ecological service impact indicators. Finally, ecosystem services were evaluated by using AHP analysis to calculate the weight of each assessment indices and apply it to the 9 village wetlands. The results of this study confirmed that the functions of the village wetlands are compliant with the ecosystem services. Based on this assessment of the unique functions of wetlands, it will serve as a methodology for assessing ecosystem services. The study was also conducted on 49 wetlands in Cheonan. The detailed assessment of wetland ecosystem services based on the wetland ecosystem function proposed by this study, was further developed as a follow-up study. It suggested that the wetland areas should be compared and be used as a general standard. In addition to the assessment of the economic value of ecosystem services provided by the village wetlands, it would be useful to assess the unique features and convert them into value.

Ecological and ecosystem database is becoming very necessary to understand origins and relationship between human and nature and also to minimize disturbance caused by human activities. An ecological information portal can play important roles as a computing system to collect knowledge, distributed research findings and separated data from researchers. In this study, we designed and developed ecological information portal service (EcoBank 1.0) for collecting and providing ecological information for diverse classes of stakeholders. To reach the goal, we had reviewed related and comparable ecological database portals to design conceptual structure of EcoBank system including database management framework. Then, we developed some functions of ecosystem analysis for each stake-holders (researchers, general public and policy makers). As a result of this study, we successfully designed of EcoBank system covering the functions of Digital Object Identifier(DOI) publishing and data quality management process. Also, we (1) applied ecological indices for calculating biodiversity by administrative boundary for policy makers, (2) provided statistical information of econature map for general public and distribution characteristics of species for researchers. To make a successful establishment of EcoBank, we have to collect and build up related database and offer various and reliable ecological data consistently. We expect that the successful construction of EcoBank will help not only to accomplish sustainable development goals but also to raise the welfare of ecosystem in Korea.

Farming practices that balance environmental friendliness with biodiversity are increasingly valuable. Wild plants on farmlands compete for nutrients with crops and create a crucial microhabitat and resources for animals such as natural enemies. Investigating farmlands and their surrounding plants with limited human and material resources has become an essential aspect of evaluating the agricultural ecosystem services. This study investigated plants in six agricultural long-term ecological research sites in Taiwan from 2017 to 2020 to determine the ideal season for investigation. Cluster analysis was performed to group habitats with similar plant composition, and the species-area curves of the clusters in each season were created. The results indicated that the agricultural ecosystem could be divided into farmlands, banks, orchards, and tea gardens. The habitats were divided into farmland, bank, Chia-Yi orchard, Gu-Keng orchard, and tea garden clusters. Ground plant cover can be investigated all year with at least 18 quadrats. However, if human and material resources are limited, 10 quadrats should be the minimum for farmlands in autumn and for the other microhabitats in spring. The minimum number of quadrats is 10 for banks, 17 for orchards, and 9 for tea gardens.

기존의 컨텐츠 전달 방법은 인터넷 서핑을 통한 획득의 개념으로 이루어졌다고 볼수 있다. IT 서비스와 유무선 인터넷 기술의 비약적인 발전에 따라 사용자는 더 이상 컨텐츠의 획득을 위해 직접 찾아 나서지 않아도 몇가지 설정만을 통해 컨텐츠가 나를 찾아오는 시대가 되었다. 이런 형태의 서비스들 중에서 최근의 단말 발전경향과 더불어 위젯 서비스가 급격히 발전하였다. 더불어 컨텐츠의 소비자이던 일반인들이 약간의 개발을 통해 직접 컨텐츠의 생산자, 배포자가 될 수 있는 개발환경이 최근에는 큰 이슈가 되고 있다. 기존의 서비스 사업자들은 직접 컨텐츠를 전달하는 어플리케이션을 개발하여 공급하였지만, Open API 를 통해 외부의 개발자들이 직접 필요한 어플리케이션을 개발하여 공유하고 수익을 배분하는 형태의 사업이 바로 Application Open Ecosystem 이라고 할 수 있다. 본 논문에서는 위젯 서비스의 Open Ecosystem 을 구축하는 방법에 대한 연구를 정리하여 소개하고자 한다.

Recently, the number of available cloud services are increasing dramatically because many IT companies have entered into cloud service market. Due to the reason, cloud service brokers are emerging as agents to solve cloud service selection problems and to support cloud service initialization and maintenance of unskilled cloud service users. In this study, NCloud24 case in South Korea and Right Scale case in the USA are analyzed as representative examples of the collaboration between original cloud service providers and cloud service brokers. The business models of two companies are analyzed using Business Model Canvas. The emergence of cloud service brokers are interpreted as unbundling process of IaaS (Infrastructure-as-a-service) cloud service companies. Based on the comparison with the two companies, we prospect future directions of cloud service brokerage.
