Complexity paradigm is a scientific amalgam that aims to unite a range of theoretical perspectives and research agendas across natural and social sciences. Proponents of complexity paradigm lay claims to an increasing number of areas of study, including artificial life, interpersonal networks, internal/international patterning of organizations, mapping of cyberspace, etc. All of those can be subsumed under the title, 'complexity turn.' Owing to the idea of open system, complexity paradigm has developed a number of new concepts/themes/perspectives that help to account for the complex mechanism of living and non-living creatures. A complex system comprises a number of properties such as disequilibrium, nonlinearity, dissipative structure, self-organization fractal geometry, autopoiesis, coevolution. Following a brief introduction to theoretical development, those properties are succinctly discussed. The complexity turn has provided a wealth of insights that enable to analyze system operations of any kind. It contributes a lot to illuminating the working of social system as well. The most remarkable attempt may be Niklas Luhmann's 'neofunctional system theory.' Merits and shortcomings of complexity paradigm were examined and its future prospect were assessed with the conclusion that complexity paradigm would continue to be useful both as effective transdisciplinary framework and powerful analytical tool.

Ecosystem models are mathematical representations of underlying mechanistic relationships among ecological components and processes. Ecosystem modeling is a useful tool to visualize inherent complexities of ecological relationships among components and the characteristic variability in ecological systems, and to quantitatively predict effects of modification of systems due to human activities and/or climate change. A number of interdisciplinary programs in recent 20 to 30 years motivated oceanographic communities to explore and employ systematic and holistic approaches, and as an outcome of these efforts, synthesis and modeling became a popular and important way of integrating lessons learned from many on-going projects. This is a brief review that includes: background information of ecosystem dynamics model; what needs to be considered in building a model framework; biologically-physically coupled processes; end-to-end modeling efforts; and parameterization and related issues.

This study distinguishes between factors that affect mental health of college students, establishes an effective approach to integrating model building, mental health promotion, and development of nursing intervention based on the Bronfenbrenner's ecological system theory. The study method investigate the causal relationship between the factors. The SPSS 20.0 program was used for general characteristics and mental health related characteristics. The fitness of the model was verified and the Amos 20.0 program was used for hypothesis verification. In the study, the fit index of the model was $x^2=614.90$ (p = .000), Q value = 3.5, GFI = .88, AGFI = .84, NFI = .92, NNFI = .94, CFI = .02, and RMSEA = .08, respectively. The results showed that stress was the most influential on mental health, and that stress coping strategies, self - esteem and parenting attitude affect mental health. In order to improve the mental health of college students, intervention should be carried out to develop nursing interventions to improve stress management, self - esteem, and coping with stress.

The process of biological invasion is led by the dynamics of a population as a demographic and evolutionary unit. Spatial structure can affect the population dynamics, and it is worth being considered in research on biological invasion which is always accompanied by dispersal. Metapopulation theory is a representative approach to spatially structured populations, which is chiefly applied in the field of ecology and evolutionary biology despite the controversy about its definition. In this study, metapopulation was considered as a spatially structured population that includes at least one subpopulation with significant extinction probability. The early phase of the invasion is suitable to be analyzed in aspects of the metapopulation concept because the introduced population usually has a high extinction probability, and their ecological·genetic traits determining the invasiveness can be affected by the metapopulation structure. Although it is important in the explanation of the prediction of the invasion probability, the metapopulation concept is rarely used in ecological research about biological invasion in Korea. It is expected that applying the metapopulation theory can supply a more detailed investigation of the invasion process at the population level, which is relatively inadequate in Korea. In this study, a framework dividing the invasive metapopulation into long- and middle-distance scales by the relative distance of movement to the natural dispersal range of species is proposed to easily analyze the effect of a metapopulation in real cases. Increased understanding of the mechanisms underlying invasions and improved prediction of future invasion risk are expected with the metapopulation concept and this framework.

Purpose: This study analyzed a path through which factors influencing death anxiety in the community-dwelling elderly, assuming personal organismic factors and microsystemic factors based on the ecology model purported by Belsky (1980). Methods: This study was performed with 189 elderly people. Data were collected through a self-report questionnaire. The data were analyzed using the SPSS and AMOS programs. Results: The factors influencing death anxiety in the elderly were depression, family support, social network, and familism value, and the explanatory power of these variables was 22%. Death anxiety increased with higher depression, higher familism value, larger social network, and lower family support. Spiritual well-being and elderly discrimination experience had indirect effects on death anxiety, and these effects were mediated by depression. Conclusion: Depression, family support, social network, and familism value were found to influence death anxiety in the elderly, and the strongest effect came from depression. To reduce death anxiety in the elderly, it is important to improve their relationship with their family and friends. Moreover, support should be provided by establishing local systems, and intervention should be provided to alleviate depression.

Since 2004, community childcare centers are legislated and the centers are running as the concept of community-oriented child welfare services. Recently child welfare paradigm are changed from simple "study room" for protection to the future capabilities of the "social welfare". For children who grow in their community, it must request to new construction with ecological system.

This study aimed to find out the formation of ecologically educational place identity of nature trails in national parks, which elementary school students to adults can understand, by analyzing the connectivity between characteristics (signs) of nature trails and elementary science environment-related key concepts and the domain of ecological education in the course of environment and by developing a semiotic interpretation model of place identity based on Barthes's semiotic theory. When analyzing correlations between the interpretation board-focused surrounding environment of nature trails and the content system of ecological education, this study found out that it showed the highest connectivity with the domain of 'System of Ecological Environment'. When analyzing the formation of place identity of nature trails in terms of semiotics, this study discovered that geographical locations or landscapes, artificial environments and physical elements as characteristics of surrounding environments mostly acted on the formation of placeness. Besides, it was found that both knowledge and attachment elements equally could act on the formation of a sense of place. Being likely to develop through interaction between placeness and a sense of place, place identity was mostly composed of behavioral internal stages and sympathetic internal stages. To diversify the formation of place identity, however, this study found it necessary to develop environment education projects and create surrounding environments and interpretation boards with the environmental uniqueness of nature trails reflected much more.

The objectives of this study is to Systematic literature review of internationalization of SMEs. Due to the economic characteristics of Korea, which depends on economic growth by exports, internationalization has become an essential management activity, not an option for SMEs. As a result, more than 400 studies related to the overseas expansion and internationalization of SMEs have been published in the past 20 years, focusing on major academic journals (such as KCI). Accordingly, the research trends used as advance research in internationalization research were analyzed of SMEs. Research targets were defined as the internationalization of SMEs and searched through 'RISS' (Research Information Sharing Service) as 'internationalization', 'global ', 'export', 'overseas expansion' and 'theory'. The analysis was carried out using a Systematic literature review. It was selected as the 76 studies and According to international research subjects and characteristics, the four areas of internationalization motive, process, outcomes, and support were analyzed. The results of the study confirmed that the most active research is focused on internationalization outcomes. This study could provide a support and the parties concerned in the ecosystem of SMEs in Korea with implications for the SMEs overseas market.

미국사회는 미혼모들의 문제를 개인적 뿐만 아니라 사회적 그리고 국가적 문제로 인식하므로 이들을 위한 다양한 사회복지 정책과 서비스, 그리고 프로그램들을 제공하여 이들이 스스로 자활할 수 있는 토대를 마련하여 왔다. 특히 십대미혼모들은 학교를 중퇴하고 직업을 갖지 못하며 빈곤한 환경에서 아이를 키우기 때문에 심리적 정신적으로 불안한 상태에 있다. 이들에 대한 서비스는 국가적으로 미혼모뿐만 아니라 어린아이들까지도 돌보는 것으로 가정과 사회의 안정을 가져오며 인적자원을 잘 보존하는 것이다. 한국의 경우도 현대화/산업화된 사회로 발전하며 청소년들의 문제가 특히나 십대 미혼모의 문제가 사회적으로 이슈화되고 있다. 따라서 이 연구는 미국의 상황을 분석하고 미국의 복지 정책, 프로그램, 자원봉사자들을 이용한 서비스들을 살펴보고 한국에 적용 가능한 복지프로그램과 지원서비스를 제안하고자 한다. 미국의 미혼모를 위한 대안 학교차원의 교육/직업훈련/부모교육 등과 가족지원프로그램은 미혼모뿐만 아니라 사회와 가족이 모두 혜택을 받을 수 있는 서비스며 프로그램이므로 한국사회에 적용하면 효율적으로 미혼모들의 어려움과 사회문제를 해결 할 수 있다고 본다. 또한 자원봉사의 서비스 체계가 미혼모를 위한 사회복지 프로그램 등에 적극적으로 활용되면 미혼모들은 믿고 따를 수 있는 롤 모델을 갖게 되며 국가적으로는 인력의 활용과 자원 절약의 효과를 기대할 수 있다.
