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.

최근 복합성의 과학에 일반인들도 큰 관심을 지니게 됨에 따라 관련책들이 많이 소개돼 있다. 다만 계통론.파국이론.정보론.사이버네틱스.공조론. 그리고 카오스에서 복잡계에 이르는 과학론의 출판추세가 일본의 출판유행을 그대로 따르는 것같아 조금은 찜찜하다.

본강좌(II)에서는 종래에 제안된 피로기구와 이론의 개요를 소개함으로서, 구조용 재료의 강도 및 복잡성을 살펴보기로 하겠다. 기계적인 각종의 원칙 및 이론은, 피로를 동반한 기계적, 금속적 또는 물리적 현상중에 어느 하나의 현상에 대해서만 적응되고 또 이론이 적용되는 영역도, 재 료에 가해지는 응력의 고저를 고려하면 피로한도근방에, 또는 피해가 발생하는 영역 그리고 소성피로를 발생시키는 영역에만 제한된다. 따라서 이와 같은 사항들을 전부 고려한 통일된 피 로기계 및 이론은 아직 찾아볼 수는 없으나, 피로를 이해하는데 초보자에게는 도움이 될 것이 라고 인식되기에, 우선 종래에 발표된 피로에 대한 각종 이론 및 구조들 중에 중요하다가 생 각되는 몇 가지만을 간추리고 그 개요를 다음과 같이 간단히 소개하기로 했다.

현대의 산업은 점차 분야가 다양해지고 기술이 첨단화되며, 고객의 요구사항이 복잡해지고 있다. 이에 따라 현대의 첨단산업에서 제조파트는 제조기술의 초정밀, 극소불량, 고신뢰도가 요구되어지고 있는 실정이다. 이런 제조파트의 핵심 기술인 SPC기법 중에서 누적합(CUSUM) 관리도는 공정의 작은 변화에 대해서 민감하다는 장점 때문에 첨단 산업인 반도체나 화학공정 등에서 활용도가 높은 관리도 기법이다. 하지만 복잡한 이론 체계로 인하여 사용편리성이 떨어진다는 단점이 있어서 널리 사용되지는 못 하고 있는 실정이다. 본 논문에서는 누적합 관리도의 이론적 전개에 관한 체계적인 동향 분석을 통해 누적합 관리도의 복잡한 이론 체계를 이해하는데 도움을 주고 더 나아가 앞으로의 제조 기술의 방향성을 제시하고자한다.

In this study, class demonstrations conducted integrating science education and 'Education for Sustainable Development (ESD)' by pre-service science teachers were analyzed, focusing on the concept of 'sustainable happiness' and the main elements of 'complexity theory'. In addition, changes before and after participating in such education implementation were analyzed from various angles. Through this, pre-service science teachers tried to derive implications for developing multidimensional teacher professionalism in ESD. The main findings are as follows. First, as a result of peer evaluation of class materials and class demonstrations designed by pre-service science teachers, the average of the integration for 'sustainable happiness' was relatively high. Next, it was analyzed that the elements of 'sustainable happiness' and 'complexity theory' generally had a positive correlation with ESD. In addition, after participating in the study, pre-service science teachers considered individual and social behavioral patterns as important in the sense of ESD. Regarding the need to integrate science education and ESD, pre-service science teachers thought it was necessary to deal with the concept of 'sustainable happiness' in science education to understand a sustainable way of life. It was analyzed that the elements of 'sustainable happiness' and 'complexity theory' generally had a positive correlation with ESD. It was found that pre-service science teachers' confidence in incorporating ESD in science classes was significantly higher after participation in the study. In addition, it was analyzed that pre-service science teachers have come to think more about the role of teachers who can communicate with students and think about happy lives together than before. Overall, it is thought that pre-service science teachers have come to think of multidimensional science teacher professionalism by applying the perspective of the teaching and learning strategy of the new ESD, which integrates the concept of 'sustainable happiness' and elements of 'complexity theory'.

The purpose of this study was aimed to analyze factors affecting on continuous intention to use of Smartphone based on the innovation diffusion theory. Also, by using the demographic characteristics were compared whether the difference in the loyalty on between user group of iOS and Android platform. Predictor factors were selected innovation, convenience, economic cost, social influence, communication channel, compatibility and complexity suggested on the innovation diffusion theory. Participants of this study were 278 Smartphone users in Busan city and Gyeongnam province in accordance with convenience sampling. IBM SPSS Statistics 19 were employed for descriptive statistics, Smart PLS(partial least squares) was employed for confirmatory factor analysis and path analysis of casual relationship among variables and effect. Analytical results show that all paths except path from complexity to the continuous intention to use and loyalty are significant. The comparison loyalty on between user group of iOS and android platform are significant. This study suggests practical and theoretical implications based on the results.

Software complexity is used to evaluate a target system's maintainability. The existing complexity metrics on web applications are count-based, so it is hard to incorporate the understandability of developers or maintainers. To make up for this shortcomings, entropy-theory can be applied to define complexity, however, it is assumed that information quantity of each paper is identical. In this paper, structural complexity of a web application is defined based on information theory and similarity. In detail, the proposed complexity is defined using entropy as the previous approach, but the information quantity of individual pages is defined using similarity. That is, a page which are similar with many pages has smaller information quantity than a page which are dissimilar to others. Furthermore, various similarity measures can be used for various views, which results in many-sided complexity measures. Finally, several complexity properties are applied to verify the proposed metric and case studies shows the applicability of the metric.
