Purpose The business ecosystem perspective offers a new lens in which to view customers. Customers as the member of business ecosystems influence firms by participating in both the firm level activities and the business ecosystem level activities. For example, customers participate in the business ecosystems by forming interest groups, allowing their voice to be heard the within business ecosystems. Customers can also, turn public opinion around and foster the business ecosystems favorable to firms. On the other hand, as an extreme case of customer participation, customers can engage in community activities to boycott the purchase of products or services from certain firms or business ecosystems. Design/methodology/approach This study views content creation and feedback activities as customer participation in the firm level. On the other hand, word-of-mouth (WOM) and boycott activities are considered as customer participation in the business ecosystem level. This study presents a research model regarding the relationships among customer socialization, customer participation, and psychological ownership. The proposed model is validated through an empirical analysis on online platform business ecosystems. Findings When the two business ecosystems are compared, different results were drawn. In the Facebook ecosystem, boycott and psychological ownership did not have a significant relationship. However, in the Kakao ecosystem, the two had a significant positive relationship. The mediating effect of the business ecosystem type sheds a light on the mission, purpose, vision, and other values associated with the theory of the business on the customer-firm relationship. Further implications for theory and practice were discussed in this study.

It is important to consider interaction between species in understanding structure and function of the biological community. Current ecological issues such as climate change and habitat loss emphasize the significance of the concept of species interaction in that varying species' interaction across environmental gradients may lead to altered ecological function and services. However, most community studies have focused on species diversity through analysis of quantitative indices based on species composition and abundance data without considering species interactions in the community. 'Ecological network analysis' based on network theory enables exploration of structural and functional properties of ecosystems composed of various species and their interactions. In this paper, network analysis of Cheonggye stream as a case study was presented to promote uses of network analysis on ecological studies in Korea. Cheonggye stream has a simple biological structure with link density of 1.48, connectance 0.07, generality 4.43, and vulnerability 1.94. The ecological network analysis can be used to provide ecological interpretations of domestic long-term monitoring data and can contribute to conserving and managing species diversity in ecosystems.

Innovation Cosystems are Conceptualized as Organizational Networks of Economic Actors, Technologies and Social Contexts that Interact for Knowledge Production, use, and Adaptation. This Paper Proposed a Conceptual Framework to Describe Value Co-creation of Organizational Networks Engaged in Technology Innovation. We Adopted Theory-Based Approach by Integrating the Perspective of Service-Dominant (S-D) Logic Into the Evolutionary Model of the Triple Helix. The Framework Gives a Plausible Explanation on how Actors Collaborate to Create Value in Dynamic Contexts of an Innovation Ecosystem. The Innovation Ecosystem can be Considered as a Composite of Sub-Ecosystems, Including Knowledge, Sectoral, and Business Ecosystems. When these Sub-Ecosystems are Recursively Transformed by Coordination of Functional Mechanisms that Serve Value Co-creation in the Innovation Process, the Innovation Ecosystem will be Re-Organized and Evolve. The case of the Digital Living Network Alliance (DLNA) was Examined to Demonstrate the Fundamental Mechanisms for Value Co-creation that was Described in the Framework. The case Study Indicates Features of Value Co-creation when Implementing Innovation in Organizational Networks.

본 연구의 목적은 생태체계이론을 적용하여 노인장기요양보험제도라는 거시체계가 가족관계라는 미시체계에 미치는 영향을 살펴보는 것이다. 이를 위해 『한국복지패널(KWPS: Korean Welfare Panel Study)』 2차년도(2007년)와 4차년도(2009년) 데이터를 활용하여 노인장기요양보험제도의 이용자 및 그 가구원(실험집단)과 비이용자 및 그 가구원(통제집단)으로 구분한 후, 노인장기요양보험제도 이용 전후의 가족관계의 변화를 살펴보았다. 이중차이모델(difference-in-difference model) 분석결과, 생태체계이론은 노인장기요양보험제도와 가족관계를 설명하는 이론이라고 할 수 있다. 주목할만하며 새로운 발견은 우리나라의 노인장기요양보험제도가 소득 효과(income effect)가 아닌 독립효과(independent effect)를 갖는다는 것이다. 이러한 결과는 무엇보다도 점점 더 가족의 의미가 퇴색되어 가족관계가 약화되고 있기 때문이다. 또한 한국의 노인장기요양보험제도가 사회보험으로서의 특징을 온전히 갖추지 못하였기 때문으로 추정된다. 노인장기요양보험은 제도의 포괄성, 급여대상의 보편성, 급여의 적절성, 서비스 접근성 측면에서의 제도개선이 필요하며, 가족친화적 사회복지제도로의 변모가 절실히 요청된다.

In this work, we analyze the spatial patterns of a predator-prey system with cross diffusion. First we get the critical lines of Hopf and Turing bifurcations in a spatial domain by using mathematical theory. More specifically, the exact Turing region is given in a two parameter space. Our results reveal that cross diffusion can induce stationary patterns which may be useful in understanding the dynamics of the real ecosystems better.

This paper presents a knowledge-based view of platform-centered collaborations among multiple organizations. Studies of technological innovation and knowledge creation have broadened beyond their initial emphasis on internal development within an organization or simple exchange of ideas between two parties toward complex collaboration among many organizations at the level of platform-based knowledge ecosystems. Platforms serve as an interface between different groups of producers and consumers in a variety of multi-sided knowledge markets such as smartphone operating systems and video games industries. This study is an exploratory examination to offer theoretical understanding of how the organizational capabilities of platform leaders help expand a network of platform participants. The growth of platform participants is particularly important in the early stage of any platforms as the concept of network effects suggests that the platform with the largest number of participants will capture entire markets. Building upon organization studies and network economics theory on multisided markets, this paper focuses on the role of platform leaders in expanding platform-based collaboration. In our view, platform leaders develop varying levels of three organizational capabilities to discern quality of potential participants, to attract them to actually participate in collaboration, and to maintain long-term exchange relations in the ecosystem. We suggest that the capabilities of platform leaders will have a positive effect on the expansion of platform participants to secure network effects, and also examine several contextual factors that moderate the relationship between a platform leader's capacity and platform expansion.

Today, In the Service Industry are more getting a lot of convergence of IT utilization. And global IT companies are strengthening that platform based Services Ecosystems. These business in the field, Ecosystem Competitive strategy is difficult to imitate. And this strategy is generated organic Business Model that a by Competitive-Predominance to brings. In addition, the added value of the Service Industry is taken, a new type of job creation by the ripple-effect is huge. However, existing the Ecosystem Theory of Business is a lack of research on the use. Thus, Ecosystem Construction conditions is very difficult. This study is try to successful Platform Case's Analysis such as Apple, Google, Amazon, eBay's. These Ecosystems is that want to know the Major attributes. At first, would be analyzing to previous research, the Service and Knowledge Services' major attributes and Ecosystem studies' major attributes to grasp. Then, from a Group of Experts is to assess the importance. Finally, according to each Platform, examined the Correlation of Major Attributes.

본 연구는 유아기 자녀를 둔 어머니의 자녀 행복 의미 구성과정을 탐색하는 데에 목적을 두었다. 연구 참여자는 유아기 자녀를 둔 어머니 16명이었고, 2회에 걸친 1:1 면담을 통해 자료를 수집하였으며, 어머니의 자녀 행복 의미 구성과정을 분석하기 위해 근거이론방법의 개방코딩, 축코딩의 패러다임 분석, 과정분석을 실시하였다. 유아기 자녀를 둔 어머니의 자녀 행복 의미 구성과정은 분리되지 않은 욕망을 따라가기, 나의 욕망과 아이의 행복 돌아보기, 얽혀있는 욕망을 조정하기, 아이와 나의 행복 찾아가기로 나타났다. 그리고 이들은 어머니의 개인적 맥락, 사회문화적 맥락, 시간체계와 상호영향을 주고받는 것으로 나타났다. 본 연구는 이상의 결과를 바탕으로 어머니가 자녀의 행복 의미를 구성해 가는 각 과정에서 나타나는 시간관, 자녀 양육과 교육에 대한 태도 및 행동과의 상호작용 특성, 행복 의미 구성에의 영향성을 논의하였다.
