We first develop a value ecosystem framework to model the SDP(Service Delivery Process) of web services. Since the web service has been evolving from the basic web architecture (e.g., traditional world wide web) to a prosuming platform based on virtualization technologies, the proposed framework of the value ecosystem focuses on capturing the key characteristics of SDP in each type of web services. Even though they share the basic elements such as PP(Platform Provider), CA(Customization Agency) and user group, the SDP in the traditional web services (so-called Web1.0 in this paper) is quite different from the most recent one (so-called Web2.0). In our value ecosystem, users are uniformly distributed over (0, ${\Delta}$), where ${\Delta}$��represents the variety level of users' preference on the web service level. PP and CA provide a standard level of web service(s) and prosuming service package, respectively. CA in Web1.0 presents a standard customization package($s_a$) at flat rate c, whereas PP and CA collaborate and provide customization service with a usage-based scheme. We employ a multi-stage game model to analyze and compare the SDPs in Web1.0 and Web2.0. Our findings through analysis and numerical simulations are as follows. First, the user group is consecutively segmented, and the pattern of the segmentations varies across Web1.0 and Web2.0. The standardized service level s (from PP) is higher in Web1.0, whereas the amount of information created in the value ecosystem is bigger in Web2.0. This indicates the role of CA would be increasingly critical in Web2.0: in particular, for fulfilling the needs of prosuming and service customization.

This study is to evaluate economic value of the ecosystem service benefits of the marine forests provided to our society on the basis of the global standard valuation manual. The main results of this study are summarized as follows: First, the ecosystem service benefits of marine forests are worth 771,121,551 won per hectare for a year in Korea. Second, when evaluating value based on the services benefits of the marine forests, as resource provisioning service, the annual value of the fishery potential production amounts to 58,512,271 won per hectare. The annual value of the environmental and regulatory services is estimated to total 29,574,000 won per hectare including 546,488 won per hectare for climate regulation, 85,342 won per hectare for pollution purification, and 28,942,170 won per hectare for erosion protection. The annual value of the culture and tourinsm services is estimated to total 15,317,647 won per hectare including 5,011,765 won per hectare for skin scuba service and 10,305,882 won per hectare for sea fishing. Also, the aunnual non-use value is estimate to 637,800,000 won per hectare. Third, assuming that the value of the sea forests increases proportionally to the unit area, the marine forests can be valued at 12.7 trillion won per year based on 12,208.2 hectares of marine forests creation area and 4,272.6 hectares of natural seaweed beds. Fourth, the total economic value of the marine forests can be estimated at 244 trillion won in 2016, if the value of the marine forests permanently continues in the future by applying 5.5% of the social discount rate. The results of this study are expected to serve as a valuable information for improving awareness of the value of marine forests ecosystem and ensuring the validity of the marine forests creation policy by converting the value of the marine forests's ecosystem service into monetary units.

Urban green spaces supply ecosystem services (ESs), which are consumed by city residents and generate demand, to improve air quality. It is important to determine supply and demand for ESs and reduce the gap for efficient management. This study proposed a method to use the concept of supply and demand for ESs in the decision-making process for urban planning or management. PM₁₀ concentrations were converted to weight for demand assessment on PM₁₀ reduction, and PM₁₀ absorption capacity of all green spaces including the forests, and that of urban green spaces excluding forests, was calculated for each supply assessment. The differences in the calculated supply and demand were analyzed to derive the mismatched regions in Suwon. As a result, regions with big forested areas showed sufficient supply, indicating that the degree of mismatch among administrative neighborhoods (dong) varied greatly depending on whether they had a forest. An analysis of only urban green spaces showed that all neighborhoods lacked supply. Forests with high PM₁₀ absorption capacity had a great effect, but urban green spaces can be considered a key element in reducing PM₁₀ in daily life. Considering the mismatch of supply and demand, spatial distribution, and population distribution, it is possible to prioritize the supply of urban green spaces to reduce PM₁₀ and, furthermore, support decision making for priority zones subject to forest conservation and designation and cancellation of green spaces, which gives significance to this study.

Exotic conifer trees have been extensively planted in southern China because of their high apparent growth and yield. These fast-growing plantations are expected to persist as a considerable potential for temporary and long-term carbon sink to offset greenhouse gas emissions. However, information on the carbon storage across different age ranges in exotic pine plantations is often lacking. We first estimated the ecosystem carbon storage across different age ranges of exotic pine plantations in China by quantifying above- and below-ground ecosystem carbon pools. The carbon storage of each tree component of exotic pine (Pinus elliottii) increased significantly with increasing age in Duchang and Yiyang areas. The stem carbon storage except <10 years in Ji'an areas was the largest component among all other components, which accounts for about 50% of the total carbon storage followed by roots (~28%), branches (~18%), and foliage (~9%). The mean total tree carbon storage of slash pine plantations for <10, 10-20 and 20-30 years across three study areas was 3.69, 13.91 and $20.57Mg\;ha^{-1}$, respectively. The carbon stocks in understory and forest floor were age-independent. Total tree and soil were two dominant carbon pools in slash pine plantations at all age sequences. The carbon contribution of aboveground ecosystem increased with increasing age, while that of belowground ecosystem declined. The mean total ecosystem carbon storage of slash pine plantations for <10, 10-20 and 20-30 years across China was 30.26, 98.66 and $98.89Mg\;ha^{-1}$, respectively. Although subtropical climate in China was suitable for slash pine growth, the mean total carbon stocks in slash pine plantations at all age sequences from China were lower than that values reported in American slash pine plantations.

Globalization, increasing technological advancements and dynamic knowledge diffusion are moving our world closer together at a unique scale and pace. At the same time, our rapidly changing society is confronted with major challenges ranging from demographic to economic ones; challenges that necessitate highly innovative solutions, forcing us to reconsider the way that we actually innovate and create shared value. As such the linear, centralized innovation models of the past need to be replaced with new approaches; approaches that are based upon an open and collaborative, global network perspective where all innovation actors strategically network and collaborate, openly distribute their ideas and co-innovate/co-create in a global context utilizing our society's full innovation potential (Innovation 4.0 - Open Innovation 2.0). These emerging innovation paradigms create "an opportunity for a new entrepreneurial renaissance which can drive a Cambrian like explosion of sustainable wealth creation" (Curley 2013). Thus, in order to materialize this entrepreneurial renaissance, it is critical not only to value but also to actively employ this new innovation paradigms so as to derive community-driven shared value that stems from global innovation networks. This paper argues that there is a gap in existing business incubation model that needs to be filled, in that the innovation and entrepreneurship community cannot afford to ignore the emerging innovation paradigms and rely upon closed incubation models but has to adopt an "open incubation" (Ziouvelou 2013). The open incubation model is based on the principles of open innovation, crowdsourcing and co-creation of shared value and enables individual users and innovation stakeholders to strategically network, find collaborators and partners, co-create ideas and prototypes, share their ideas/prototypes and utilize the wisdom of the crowd to assess the value of these project ideas/prototypes, while at the same time find connections/partners, business and technical information, knowledge on start-up related topics, online tools, online content, open data and open educational material and most importantly access to capital and crowd-funding. By introducing a new incubation phase, namely the "interest phase", open incubation bridges the gap between entrepreneurial need and action and addresses the wantpreneurial needs during the innovation conception phase. In this context one such ecosystem that aligns fully with the open incubation model and theoretical approach, is the VOICE ecosystem. VOICE is an international, community-driven innovation and entrepreneurship ecosystem based on open innovation, crowdsourcing and co-creation principles that has no physical location as opposed to traditional business incubators. VOICE aims to tap into the collective intelligence of the crowd and turn their entrepreneurial interest or need into a collaborative project that will result into a prototype and to a successful "crowd-venture".

생태계 평가 연구는 대부분 토지피복 정보를 기반으로 하여 연구되며, 주로 전지구적인 범위로 이루어져 왔다. 그러나 이러한 결과들을 지역적 현안에 대한 의사결정 자료로 활용하기에는 범위와 스케일에 있어서 활용성이 떨어지는 측면이 있다. 지역적 스케일에 활용 가능한 토지피복 정보로는 환경부에서 제작된 토지피복도가 있지만 시각판독법(On Screen Digitizing Method)의 한계와 시기별, 지역별 차이로 인해 자료 활용에 제한이 있다. 본 연구는 객체기반 분류기법을 이용하여 UAV 영상의 중분류 토지피복도를 제작하는데 목적이 있다. 이를 위하여 고해상도 UAV 영상을 5m 공간해상도로 재배열한 후 영상분할을 수행한 결과 scale 20, merge 34가 최적의 가중치 값으로 나타났으며, RapidEye 영상 분할에서는 scale 30, merge 30이 중분류 수준에 적절한 가중치 값으로 나타났다. 토지피복도는 예제기반분류를 사용하여 제작하였고, 층화추출법을 사용하여 정확도 검증을 수행하였다. 그 결과, RapidEye 분류 영상은 90%, UAV 분류 영상은 91%로 양호한 토지피복분류 결과가 도출되었다.

블록체인 생태계의 혁신을 촉진하는 암호화폐가 여러 목적을 위해 발행됨에도 불구하고, 투자자들은 암호화폐를 시세 차익의 수단으로만 인식한다. 이는 암호화폐의 투기적 측면만을 부각해 암호화폐가 발행되는 근본적인 목적이 무시되고, 블록체인 생태계의 혁신을 방해한다. 본 연구에서는 암호화폐 투자자들의 투기적 행동 원인을 학문적 관점에서 규명한다. 개인들이 기존 주식, 벤처 투자 시 사용하는 의사결정 기준을 통합하고 암호화폐 투자 시 고려해야 할 기준을 추가해 통합하였다. 확립된 모델을 바탕으로 암호화폐에 대한 그릇된 인식의 원인을 제한된 합리성 이론으로 뒷받침한다. 의사결정 기준 정립을 위해 전통적인 벤처 및 엔젤 투자자들이 투자 의사결정 시에 사용하는 변수를 차용하고, 암호화폐 속성을 반영하기 위해 백서의 목차에서 나타난 키워드를 수집하여 암호화폐 투자에 적용 가능한 새로운 변수들을 도출하였다. 본 연구는 Simon이 제시하는 제약들로 인해 개인들이 암호화폐를 투기의 수단만으로 인식하고, 생태계의 건전성을 저해하는 비합리적인 의사결정을 행할 수밖에 없게 된다는 것을 설명한다. 이를 위해 우리는 제한된 지식과 불완전한 정보의 제약을 바탕으로 나누어진 표본이 내린 의사결정에서 합리성의 유의미한 차이가 있는지 분석한다. 그 결과, 불완전한 정보는 투자자들이 비합리적인 기준만을 고려하도록 야기했다. 이 결과로부터, 본 연구는 개인들의 합리적인 투자와 블록체인 생태계의 발전이 함께 추구되기 위해 정보 비대칭이 완화되어야 할 필요가 있음을 시사한다. 또한, 산업이 개인 투자자들의 의사결정에 대하여 더 나은 이해를 가능하게 함으로써, 추후 ICO에서 성공적인 자금 조달이 가능하도록 전략적 인사이트를 포착할 수 있다.

Recently, electronic-book (e-book) market is growing rapidly due to the evolution of information technology and e-book standard EPUB. Users can search e-book on-line and download easily to their e-book readers such as amazon's kindle or smartphones. On the other hand, there is lack of e-book contents for the reading disabled people because of high cost of making e-book accessibility for the reading disabled people. If we can translate EPUB specified e-book contents to the alternative e-book contents suitable for the reading disabled people, then there are many advantages to acquire various types and large volumes of e-book contents for the reading disabled people. This paper suggests a new electronic publishing ecosystem for the reading disabled people using e-book translation method. It also suggests a promotion strategy of e-book market for the reading disabled people.
