Purpose - In today's markets, new technologies such as social network systems and user generated contents have provided consumers with access to unlimited amounts of information and an ability to communicate with other consumers in the world. Specially, the massive of the internet and the development of online communities and interactive platforms offer the potential to cocreate with a large number of consumers. Significant changes in marketplace suggest that simply being consumer oriented is not enough, so firms must learn from and collaborate with consumers to create values that meet their individual and dynamic needs. In these sense, emergent perspectives in marketing highlight new opportunities for co-opting consumers as a means to define and cocreate value through their engagement. Although the importance of consumer co-creation with firms, the current literature lacks the respond to two questions: (1) who are the most competent consumers for creating the values with firm? and (2) what are the stimulaters to help the consumers engage for co-creation? To this answer the question, this research investigate how to structure consumer motivations to encourage consumers to be more engaged for co-creation and what drives a consumer to get involved to respond to a call for co-creation. Research design, data, and methodology - To empirically test the hypotheses, a survey was conducted among consumers who had experienced the co-creation including upstream, downstream, autonomous, and sponsored co-creation with the firms. We collected a total of 343 responses. After we excluded 37 questionnaire because of incomplete responses, a total of 306 questionnaire remained. Working with a sample of 306 responses in Seoul and Kwangju, hierarchical moderated regression is employed to test research hypotheses. Results - The results indicated that consumer creativity and emergent nature are positively related to engagement in co-creation including upstream, downstream, autonomous, and sponsored co-creation. Also, the relationships between consumer creativity/emergent nature and engagement in co-creation were moderated by intrinsic motivation in case of upstream and downstream co-creation. Finally, interaction effects between consumer creativity/emergent nature and extrinsic motivation were not significant. Conclusions - These results suggest that marketing managers have to consider the consumer personality such as creativity and emergent nature and stimulate the intrinsic motivation of consumer to achieve the co-creation project successfully.

This article describes the latest development of a generic approach to detecting emerging trends and transient in scientific literature. The work makes substantial theoretical and methodological contributions to progressive Information analysis. A specialty is conceptualized as a time variant duality research front concepts in information science. A research front is defined as an emergent and transient grouping of concepts and underlying research issues. The contributions of the approach is that the nature of an intellectual base is algorithmically and temporally identified by emergent research-front terms. The modeling process is implemented in RADERS, and applied to the analysis of telecommunication field. Practical implications of the work are discussed. A number of challenges and opportunities for future studies are identified.

Star forming galaxies found in the early universe exhibit asymmetric Lyα emission line that results from multiple scattering in a neutral thick medium surrounding the Lyα emission source. It is expected that emergent Lyα will be significantly polarized through a large number of resonance scattering events followed by a number of successive wing scatterings. In this study we adopt a Monte Carlo method to calculate the polarization of Lyα transferred in a very thick static slab of H_I. Resonantly scattered radiation associated with transitions between is only weakly polarized and therefore linear polarization of the emergent Lyα is mainly dependent on the number of off-resonant wing scattering events. The number of wing scattering events just before escape from the slab is determined by the product of the Doppler parameter a and the line center optical depth τ₀, which, in turn, determines the behavior of the linear polarization of Lyα. This result is analogous to the study of polarized radiative transfer of Thomson scattered photons in an electron slab, where the emergent photons are polarized in the direction perpendicular to the slab when the scattering optical depth is small and polarized in the parallel direction when the slab is optically thick. Our simulated spectropolarimetry of Lyα shows that the line center is negligibly polarized, the near wing parts polarized in the direction parallel to the slab and the far wing parts are polarized in the direction perpendicular to the slab. We emphasize that the flip of polarization direction in the wing parts of Lyα naturally reflects the diffusive nature of the Lyα transfer process in thick neutral media.

Furniture design is no exception to human desire for pursuit of the nature. In various design fields, it has turned out nature-decorative method in the past, and also recently it has turned out bio-adaptive method which is more root design process using principal of generation in nature world. The purpose of this study is to analyze application methods and characteristics of fractal geometry and voronoi diagram which are most representative principals of generative design in nature by research on the example of furniture design using these principals. The results of having analyzed fumitures by generative design can be summarized as follows; design principals of fractal; superposition, scaling, repetition & gradation, deformation, distortion and voronoi diagram; individual speciation, variational patten, repetition gradation, ambiguous boundary create new design concept and emergent form in furniture design. Application methods are 'form emergence by algorithm', 'conventional process based on principals of generative design', and 'reproduction of pattern from generative design'. Biological reinterpretations and new explorations of principals of nature generation offer unbounded possibilities for furniture design.

본 연구는 새로운 세계관으로서의 전환에 대해 주목하고 그 변화의 경향이 동양적 사유 방식과 유사한 관계형성 도구라는 것에 초점을 맞춰 한국 전통정원인 소쇄원에 대해 새로운 해석을 시도하고자 한다. 따라서 개별적 구성요소들의 특성보다는 관계를 통해 전체를 바라보려는 복잡성 이론에 기초하여 소쇄원과 연결, 재해석하는데 목적이 있다. 연구결과를 요약하면 다음과 같다. 첫째, 물리적 차원의 공간과 열린 시스템에 나타난 복잡성의 특성은 '사건(상황)', '비결정성', '부분과 전체의 상동적 관계' 등 세 가지로 나타났으며, 다양한 기법들은 자연을 적극적으로 도입하고 있는 것으로 나타났다. 특히, 지형의 이용이 많은 이유는 소쇄원의 경우 부지를 적극적으로 선택하였고, 그 주어진 자연지세의 흐름에 순응하며 건축하였기 때문에 나타난 결과이다. 이것은 창발적 상황에 열린 텍스트로서의 성격을 갖게 된다. 둘째, 비가시적 차원으로서의 경험과 열린 시스템에 나타난 복잡성의 특성은 '사건(상황)', '행위자와 환경간의 상호 감응관계'가 주로 나타났으며, 다양한 기법들은 자연과 일상의 경험이 결합되어 상호작용하는 공간으로 나타났다. 이는 주체와 객체, 인간과 자연 사이의 상호작용을 바탕으로 한 양방향의 어울림의 전형이라 할 수 있으며, 삶의 일시적 행태를 담아내는 창발적 공간이 된다. 셋째, 자기조직화를 통한 감성언어와 체험에서의 구성요소들은 고정적 관계들을 해체하고 유기성을 가진 공간으로 재구성된다. 특히 '소쇄원 48영'은 현재의 행위자들에게 소쇄원의 감성적 공간체험을 위한 원천이 되어준다. 결국 소쇄원 공간에서의 행위자는 동시에 공간의 창출자가 되며, 환경과 상호텍스트 된 새로운 공간을 생성한다. 그러므로 소쇄원은 인간과 자연, 전체와 부분의 유기적 사고를 바탕으로 상호관계를 유지하면서 나와 타자를 결속시켜주는 장소가 되는 것이다.

This study was carried out to suggest the baseline data necessary for vegetation restoration at riverine wetland within stream corridor. We used the prevalence index for wetland assessment by applying the method of weighted averages with index values based on five hydrophyte indicator status as defined by estimated probability occurred in wetland. We selected near nature and urbanized reach of Gap and Yanghwa streams as experimental site. Although two sites have some different disturbance and characteristics of watershed, they showed that similarity of vegetation community including three dominant species - Salix koreensis, Phragmites communis, Miscanthus sacchariflorus - was very high. But in case of Yanghwa stream, various kinds of emergent plants along wetted condition were distinctly occurred, resulted from difference of hydrological regime and substrate, etc. Degree of naturalness of vegetation at the sampled areas indicated that near nature area of Gap stream and all area of Yanghwa stream were fitted as riverine wetland, while urbanized area of Gap stream has changed into upland condition. In conclusion assessment system using prevalence index would be considered an effective method for evaluating of natural states of riverine wetland, but further integrated consideration of physical, hydrological, and biological factors of stream process, and also with considering the difference between those qualitative data of vegetation community.

Literacy acquisition is a social phenomenon. Children in a literate society grow up with literacy as an integral part of their personal, familial, and social histories. Because it is language, children learn written language in ways similar to oral language. However. because it is written, the ways in which written language differs from oral language in terms of its different functions and forms affect the way in which children learn written language. Written language is likely to be more decontextualized than spoken language. The ability to use decontextualized language seems to be crucial to successful participation and progress in school. Experiences identified as contributing to preschool children's literacy development contribute to their ability to use language in a decontextualized way. Teale and Sulzby's(1986) metaphor of emergent literacy has provided a conceptual scheme for understanding the nature and process of literacy acquisition in early childhood.

The framework, described in this paper, involves artificial evolutionary systems that re -produce aimed solutions through a simulated Darwinian evolution process. Through this process the framework designs structures of machines innovatively and emergently especially in the stages of conceptual and basic design. Since the framework simulates the evolution of nature, it inevitably involves processes that converse the natural evolution to the artificial evolution. For the conversion, based on several methods as the building block modeling, Artificial Life, evolutionary computation and the law of natural selection, we propose a series of processes that consists of modeling, evaluation, selection, evolution etc. We have demonstrated the implementation of the framework with the design of multi-step gear systems.

Construction is one of the most hazardous industries due to its unique nature. Recent occurrences of highly publicised and criticized construction site accidents have highlighted the immediate need for the construction industry to address safety hazards. Safety used to be addressed as an isolated issue in the past, but the problem of safety is an emergent property of a system. In general, it seems that both industrial practitioners and government officials have tended to address safety by focusing on technical aspects and looking for immediate causes of accidents after they have taken place. The objective of this paper is to examine issues and critical factors that affect the safety standards from a holistic point of view. The job of making worksites safe should not just fall squarely on the contractors but should be shared by all parties in the value chain of construction activities.
