In countries and regions population plays an important role. Recently the importance of population migration increased as population growth slowed. Researches on population migration are mainly focused on the analysis of the population movement factors and the regional structure analysis using the network analysis method. Analysis of regional structure through population movement is not enough to explain the phenomenon of migration of small cities and rural regions. In this study, to overcome the limit of previous studies the characteristics of the population movement rate according to the size of the population were analyzed. Also network analysis using the population movement OD (Origin and Destination) and population movement rate OD were conducted and the results of them were compared. As the results of analysis by the regional population scale, the population movement by population size showed a big difference in the areas with more than 100 thousand people and less than 100 thousand people. Migration to the outside of the province was the most frequent in regions with 30,000~50,000 people. The population migration rate network analysis result showed that the new area with large population inflow capacity was identified, which could not be found in the population movement network analysis because population movement number is small. The population movement rate irate is expected to be used to identify the central regions of the province and to analyze the difference in resident attractiveness.

본 연구의 목적은 IMF 외환위기 기간(1996-2001)동안의 지역 자료를 활용하여, 지식기반경제에 있어서 지역의 지식연계망 기능을 분석하는데 있다. 특히, 지역혁신과 관련하여 지역간 지식연계망에 관한 다음과 같은 사항을 구명하고자 하였다. 첫째, 지역에서 지역간 지식연계망을 어떻게 구별할 수 있는가? 둘째, 실물 경제와 지역간 지식 연계망의 관계는 무엇인가? 이러한 의문 사항을 해결하기 위하여, 본 연구에서는 실물 경제의 변화와 지역간 지식연계망 간의 관계를 분석하기 위해서 사회 연계망 분석법을 활용하였으며, 실증분석을 위해서 1996년부터 2001 년까지의 16개 시도의 지역 고용 자료를 사용하였다. 주요 분석 결과로는 먼저 지역간 지식연계망의 집중도와 실물 경제의 경제성장률과는 양의 상관관계를 갖고 있는 것으로 나타났으며, 또한 지역간 지식연계망의 밀도와 표준편차는 실물 경제의 경제성장률과는 음의 상관관계를 갖고 있는 것으로 분석되었다.

Natural disasters often lead to regional failures that can cause network nodes and links co-located in a large geographical area to fail. Novel approaches are required to assess the network vulnerability under such regional failures. In this paper, we investigate the vulnerability of networks by considering the geometric properties of regional failures and network nodes. To evaluate the criticality of node locations and determine the critical areas in a network, we propose the concept of ${\alpha}$-critical-distance with a given failure impact ratio ${\alpha}$, and we formulate two optimization problems based on the concept. By analyzing the geometric properties of the problems, we show that although finding critical nodes or links in a pure graph is a NP-complete problem, the problem of finding critical areas has polynomial time complexity. We propose two algorithms to deal with these problems and analyze their time complexities. Using real city-level Internet topology data, we conducted experiments to compute the ${\alpha}$-critical-distances for different networks. The computational results demonstrate the differences in vulnerability of different networks. The results also indicate that the critical area of a network can be estimated by limiting failure centers on the locations of network nodes. Additionally, we find that with the same impact ratio ${\alpha}$, the topologies examined have larger ${\alpha}$-critical-distances when the network performance is measured using the giant component size instead of the other two metrics. Similar results are obtained when the network performance is measured using the average two terminal reliability and the network efficiency, although computation of the former entails less time complexity than that of the latter.

본 연구는 신산업으로서 광산업(photonics industry)과 광주 광산업 집적지의 성장에 관심을 두고 국내 광산업 성장의 지역적 특성을 탐구하였다. 연구를 위해 광산업 성장의 행위주체 기반이 되는 광산업체와의 심층면담을 토대로 광산 업체의 입지와 사업네트워크를 살펴보았다. 이를 통해 신산업인 광산업의 성장과 함께 광산업을 전략산업으로 육성하고자 하는 지역산업육성정책의 의미를 되짚어보고자 했다. 연구 결과, 시장과 정책의 이점으로 대비되는 수도권과 광주에서 광산업의 차별적 성장을 관찰할 수 있었다. 광산업을 육성하려는 광주의 지역산업육성정책은 다양한 지역주체들의 공감대 형성, 산업발전의 원천이 될 모멘텀과 다양성 부여의 측면에서 의미를 갖는다고 보겠다.

Purpose This paper examines the role of local market-based communities in driving regional revitalization, using detailed analysis of online networks. We aim to dissect a local community's communication network, highlighting members with high engagement levels and exploring their characteristics. Our goal is to identify the conditions that allow local community networks to grow independently and to demonstrate how the activation of these networks contributes to regional revitalization. Design/methodology/approach We employ a mixed-methods approach, combining social network analysis with statistical techniques to investigate the structure of online communication networks. Specifically, we use ANOVA to determine the statistical significance of our findings, ensuring their reliability. To complement our quantitative data, we include qualitative insights from interviews, adding depth and context to our analysis. Findings Our results show that individuals with high centrality in the online network are crucial for maintaining active local communities. We find that leveraging local resources to create a supportive and adaptable environment is essential for the communities' sustainability and expansion. Importantly, our research draws a direct connection between the vitality of local community networks and the broader process of regional revitalization. We argue that energizing local communities is an effective way to address the risk of regional decline. By integrating quantitative analysis with qualitative feedback, this study contributes to the understanding of local market-based communities as key drivers of regional development. It emphasizes the importance of building vibrant, resourceful community networks to revitalize areas experiencing socio-economic challenges.

This study is a structural analysis of a multi-type and multi-level library network within the framework of a regional interlibrary loan (ILL) system. The study monitored to information network structure for resource sharing of academic and research library materials transmitted through the ILL. The local flow of academic and research information was measured by a survey of the filled ILL transactions by individual libraries in the Western 3Rs region. The major findings were as follows: 1) the regional ILL network showed less than half of participation of the total subject libraries, 2) existing structure surveyed was identified as a composite centralized network with three communication groups, 3) depending on the types of materials transacted, the structure were changed, 4) statewide and multi-state library cooperatives had direct interactions with some of the local libraries, 5) individual libraries participated in the ILL network more for periodicals than book materials, 6) academic libraries throughout the total six structure analyzed showed the highest percentage of participation.

In this paper, our proposed system uses the regional Gabor wavelet and Neural Network to implement face recognition similar to human face recognition system, because the Gator wavelet expresses visual recognition system of human mathematically and the regional Neural Network is robust to white noise and partial illumination. This system consists of two stages of building database and recognizing face. One is composed by using the supervised learning of Neural Network. At this time, the Neural Network is applied to the upper and the lower part of face images respectively. The Backpropagation algorithm is used to learn Neural Network. Another consists of calibration of slope of face image, measurement of illumination variant using deviation with average face image and similarity comparison using Euclidean distance measure.
