송신자 개시 부하 균등 알고리즘에서는 전체 시스템이 과부하일 때 송신자(과부하 프로세서)가 부하를 이전하기 위해 수신자(저부하 프로세서)를 발견할 때까지 불필요한 이전 요청 메시지를 계속 보낸다. 따라서 이 같은 상황에서는 저부하 상태인 수신자 프로세서로부터 승인 메시지를 받기까지 불필요한 프로세서간 통신으로 인하여 프로세서의 이용률이 저하되고 또한 태스크의 처리율이 낮아지는 문제점이 발생한다. 본 논문에서는 이질형 분산 시스템에서의 동적 부하 균등을 위해 진화알고리즘을 기반으로 하는 접근 방법을 제안한다.

This paper explores the life cycle of innovation cluster, especially focussing on the Korean representative innovation cluster, Daedeok Innopolis. For this purpose, we review theoretically how an innovation cluster has been growing up. In particular, we discuss how a cluster has been formed and activated by governmental innovation policies from an evolutionary perspective. By doing so, the study identifies the typical features of an innovation cluster according to each dimensions of the cluster life cycle. The results of this study are as follows: First, in this study, Daedeok Innopolis has characteristics of latency, emergence, growth, and maturity from evolutionary perspective. Second, the governmental structure of the Daedeok Innopolis is a strong government-led and top-down structure, which has features of inclusiveness and flexibility such as umbrella policy. Third, the Daedeok Innopolis can be seen that adaptive or renewal development, as while, it can be applied fine adjustment the innovation cluster policy towards the recognition of innovation obstacle at each dimensions of the life cycle. Therefore, these discussions expose what kind of policy interventions should be addressed to form and develop the innovation cluster according to the cluster life cycle, as while, the development of adaptive policies during the risk and take-off period. Ultimately, the study provides that a different kind of policy instruments and tools should be implemented according to innovation cluster development and its distinctive characteristic per each dimensions of the cluster life cycle.

This article aims to search for moral educational implication of J. D. Greene's recent neuro-scientific approaches to deontological ethics. Recently new technique in neuroscience such as fMRI is applied to moral and social psychological concepts or terms, and 'affective primacy' and 'automaticity' principles are highlighted as basic concepts of the new paradigm. When these principles are introduced to ethical theories, it makes rooms of new and different interpretations of them. J. D. Greene et al. claim that deontological moral judgments or theories are just a kind of post hoc rationalization for intuitions or emotions by ways of neuroscientific findings and evolutionary interpretation. For example, Kant's categorical imperative in which a maxim should be universalizable to be as a principle, might be a product of moral intuition. Firstly this article tries to search for intellectual backgrounds of the social intuitionalism where Greens' thought originates. Secondly, this article tries to collect and summarize his arguments about moral dilemma responses, personal-impersonal dilemma catergorizing hypothesis, fMRI data interpretations by ways of evolutionary theory, cultural and social psychological theories, application to deontological and consequential theories, and his suggestion that deontological ethics shoud be rejected as a normative ethical thought and consequentialism be a promising theory etc. Thirdly, this tries to analyse and critically exam those aspects and argumentation, especially from viewpoints of the ethicists whose various strategies seek to defeat Greene's claims. Fourthly, this article criticizes that his arguments make a few critical mistakes in methodology and data interpretation. Last, this article seeks to find its implications for moral education in korea, in which in spite of incomplete argumentation of his neuroscientific approach to morality, neuroethics needs to be introduced as a new approach and educational content, and critical materials as well.

The purpose of this study is to analyze and illustrate 'Rhizome', a postmodern speculation system based on de-subjectivity and decentralization, presented by Gilles Deleuze. He borrowed the word rhizome, an originally botanical term meaning a horizontal stem under the surface of the earth, to counteract the dominating system grounded on binary, root-tree structure. The study then criticizes the early movements of de-subjectivity with molecular-biological and evolutionary evidences, and proves that these evidences can only be characterized by chance and nomadism, which are the key elements that constitute Rhizome. As a practical example of Rhizome, the study analyzes the film by Gus Van Sant, and demonstrates that both his various cinematic experiments and the result bear the same characteristics as Rhizome.

Following the emergence of a knowledge-based economy, the role of universities in regional development has been re-evaluated through considering localized interactive learning processes. This paper tries to identify the role of universities for regional development and the variables effecting on their localized engagement in regional development. We argues that universities cannot be viewed as a single angle, because the behaviors of a university are influenced by the degree of their independence from regional and national governments. Likewise, the contributions of universities to their regional development can be differential depending on the organizational characteristics of individual universities, the social, political, and economical contexts of a given region and nation, and complex relations between and within universities and other regional stakeholders. These variables can be both the drivers and barriers when each university responds to regional needs. Based on the literature review, we suggest that the explanatory factors of shaping the engagement of universities in regional development can be classified into four categories: the characteristics of individual universities, the national context, the local and regional context, and the policy context.

Traditionally, economic growth has been uneven over the space. It has also been true for the recovery from social and economic crisis in old industrial areas of the advanced economies. Even if many of such old industrial areas were seriously affected by de-industrialization, some areas have been showing progress, while others have not been so. While interpreting this phenomenon used to be a key issue in economics, main stream liberal economic theorists' explanation was uneven distribution of economic resources, such as raw materials, labour and money. However, some revolutionary economic theorists have brought in the concept of "history" in explaining the phenomenon. Path dependence theorists, for example, interpretate the emergence of different growth paths with the concept of historical accidents. This contrasts to the recent argument of the group of scholars suggesting the concept of "regional resilience," who argue that uneven growth and different growth paths are originated from different regional resilience. This paper introduces the backgrounds, characteristics and utilities of the two theories: path dependence theory and the concept of regional resilience.

This study examines the major changes of research about science and technology administrative system and innovation governance, and suggests future direction through critical review. The subjects of the analysis are papers of such as Korean Public Administration Review, Journal of Technology Innovation and policy reports and government documents published by national research institutes. As a result of the analysis, the research itself has evolved from the part of the government organization to the unique field and main focused historical, normative, comparative analysis and institutional approach. In addition, coordination and integration of science and technology policies have been regarded as important issues in research, and innovation system (NIS) and governance perspectives have begun to be reflected in research. However, it reveals some issues such as small government theory vs big government theory, governance theory vs control tower theory, and shows limitations in problem definition and solution inconsistency, and lack of grand and detailed discourse. Future challenges include the pursuit of evolutionary rationality, the pursuit of diversity in multidimensional research and methods, development of korean policy theory and securing universality.

본 연구에서는 허브와 스포크의 입지선정과 차량 경로가 통합된 hub-and-spoke 네트워크 설계문제를 다룬다. Hub-and-spoke 네트워크는 대량화와 공동화를 통해 물류효율화를 실현하기 위한 대표적인 구조로 물류시스템에서 흔히 사용되고 있다. 이러한 물류시스템에서 물류비용의 절감과 고객서비스 향상을 위한 효율적인 수송네트워크 설계는 매우 중요하다. 전통적인 hub-and-spoke 네트워크 설계문제에서 각 스포크의 위치와 화물량이 미리 주어진 상황에서 허브의 입지를 결정하였다. 하지만 스포크 역시 스포크가 담당하는 고객들의 위치와 담당 영역에 따라 그 위치와 수, 그리고 화물량이 변할 수 있다. 또한 정확한 비용산출을 위해서는 스포크에서 고객으로의 수집과 배달을 위한 차량경로가 함께 고려되어야 한다. 다루는 수송망 설계문제는 상호 관련성 있는 여러 부분문제가 결합된 통합문제로써 이를 해결하는 방법으로 기존의 발견적 방법에 의한 순차적 기법은 한계가 있다. 본 연구에서는 공생 진화알고리듬 기반의 방법론을 채용하여 다루는 수송망 설계문제를 동시에 통합적으로 해결할 수 있는 알고리듬을 개발한다. 실험을 통해 개발한 알고리듬의 우수성과 그 적용성을 보인다.

In a sender-initiated load balancing algorithm, a sender continues to send unnecessary request messages for load transfer until a receiver is found while the system load is heavy. Therefore, it yields many problems such as low cpu utilization and system throughput because of inefficient inter-processor communications until the sender receives an accept message from the receiver in this environment. This paper presents an approach based on evolutionary algorithm. The processors to which the requests are sent off are determined by the proposed algorithm to decrease unnecessary request messages.
