This paper aims to critically review the geographical literature on learning and proximity that stresses the role of the regions and geographical proximity in sustaining competitive advantage, and to conceptualize a relational/organizational perspective on the sources of knowledge and learning in the firm. In the first part of the paper, I argue that the geographical literature lacks the deliberate scrutiny of how learning occurs in the firm and where the sources of knowledge and learning come from. Secondly, I attempt to elaborate the concept of proximity through a relational/organizational perspective. Thirdly, I delve into how learning takes place and is realized in the firm through communities in the firm such as communities of practice, epistemic communities and task-force teams and how such communities in the firm generate knowledge and sustain loaming by drawing on relational/organizational proximity. This paper concludes by claiming that the sources of learning exist in organizational spaces, with complex geographies mobilizing distributed knowledge and competences and combining varied forms of knowledge beyond the simple demarcation of tacit and codified knowledge.

일반적으로 의사결정의 대상이 되는 현실 시스템은 매우 가변적 (variable)이며 때로는 많은 불확실성(uncertainty)이 포함된 상황에 놓일 수 있다. 이러한 문제의 처리를 위한 통계적 방법으로 유의수준이나 확신도, 민감도 분석 등이 사용된다. 본 논문에서는 먼저 근접관계 행렬에서 근접도를 구하는 방법으로 상대적 해밍거리와 max-min방법을 이용한 다음, 다중임계치를 사용하여 최적구간분할을 하는 방법을 제안한다. 결과적으로 max-min방법을 이용하여 다중임계치을 적용한 근접관계의 분류가 상대적 해밍거리로 근접도를 구하여 다중임계치를 구하는 방법보다 계산과정이 더 간단하고 명확하며 분할과정을 줄일 수 있고 최적의 의사결정에 효율적이라는 것을 알 수 있다.

The main aim of this article is to examine theoretical issues on the 'global-local connectivity' of regional industrial cluster and regional innovation system which have been presented since the 2000s in terms of three different aspects. Firstly, the concept of 'geographical proximity' is discussed within the context of its importance for the regional industrial development by considering relationships of cluster, local buzz and global pipeline. Secondly, concepts on knowledge gatekeeper and temporary cluster are explored with respect to their role of a mediator in forming or transforming global-local connectivity. Finally, policy implications of the global-local connection are presented. Authors arguments are as follows; firstly, in order to improve regional industrial cluster on the basis of geographical proximity, relational proximity which is beyond different spatial scales has to be secured. It means that geographical convenience and inconvenience are required simultaneously for regional industrial development. Secondly, A base of the global-local connectivity is socal capital and embeddedness. Therefore, it needs to understand that relational proximity is embedded into different culture and habit at different spatial scales. Finally, within the context of the global-local connectivity, in order to overcome spatial hierarchy by the division of labor of firms, it needs to consider the complex system which is composed of vertical and horizontal hierarchy by the spatial division of labor by firms, openness and closeness of clusters, and the scope of policies' inclusion and exclusion by central and local governments.

Generally, real system that is the object of decision-making is very variable and sometimes it lies situations with uncertainty. To solve these problem, it has used statistical methods as significance level, certainty factor, sensitivity analysis and so on. In this paper, we propose a method for fuzzy decision-making based on MFAC(Multiple Fuzzy Alpha Cut) to improve the definiteness of classification results with similarity evaluation. In the proposed method, MFAC is used for extracting multiple a ${\alpha}$-level with proximity degree at proximity relation between relative Hamming distance and max-min method and for minimizing the number of data which are associated with the partition intervals extracted by MFAC. To determine final alternative of decision-making, we compute the weighted value between extracted data by MFAC From the experimental results, we can see the fact that the proposed method is simpler and more definite than classification performance of the conventional methods and determines an alternative efficiently for decision-maker by testing significance of sample data through statistical method.

Since the advent of the internet as representative of the development of information communication technology (ICT), information transfer forms have changed rapidly these days. In the new techno-economic paradigms, I would ultimately consider how spatial structures of a knowledge-based service industry have been altered dynamically. To delve into this background, this study conducts an empirical case study of the internet advertising industry, particularly, among the whole advertising industry. Therefore, the primary objective of this study is to identify dynamic characteristics of spatial networks among actors for knowledge creation in Korea's internet advertising industry. In addition, it also is to analyze the formative elements of spatial networks which would have an influence on constructing the space of new economic activities. There are multilateral approaches. This research is classified into types of actors such as inter-firm, intra-firm, and firm-customer, and categorized according to spatial ranges such as local, regional, global levels. In the meanwhile, formative factors of the spatial networks could draw a conclusion from two aspects: inter-firm networks in the process of business in the internet advertising industry, and individual networks in the nonoccupational aspect. Accordingly, the results of this study suggest that actors' networks of two perspectives would make mutually complementary relationships and create new relational spaces in the digital economy.

The Document Management System(DMS) is a system which retrieves and manages library information efficiently. Since DMS manages the information using only one table, it does not need to provide join and view operations that spend high cost in traditional DBMS. In addition, DMs requires new operations because of their property. the operation has not been supported in existing DBMSs. In this paper we define a data language which represents the structure definition and process of data on the DMS. Especially we define Ranking and Proximity operation which is needed in Document Retrieval,. We also design and implement a query processor to process the query constructed with the data language. When the exiting query processors of relational DBMS are used as a query processor of DMS, they degrade the whole system performance. The proposed query processor not only overcomes such a problem but also supports new operation which is needed in DMS.

This paper aims to provide a context-specific interpretation on the shifting process of in-house R&D spaces in a large Korean firm in the context of rapidly changing markets and technology. Drawing on the case study of LG Electronics Company, one of the Korea's flagship companies, I examine the causes and mechanisms leading to a shift in domestic R&D spaces and the nature of learning processes between R&D teams and between R&D and other organizational units, particularly manufacturing. It appears that the current reshaping processes of domestic R&D spaces in LGE focus more on the clustering of core R&D laboratories than the geographical integration of conception and execution. However, it should not simply be viewed that such a move would be reduced to the linear model of innovation and organizational learning. Instead, it involves the firm-specific mode of regulating organizational competences. As contextual variables to induce such a firm-specific mode of organizational change, I consider the spatial form of organization, the spatial sources of knowledge and learning, and the powers of relational learning that can be made between distanciated actors and teams.

This paper aims to explore organisational change and learning involving spatial processes and outcomes. In particular, it focuses on the context specific nature of corporate learning and organisational change that can be found in the case of a large Korean firm facing radical economic change. Drawing on the case study of a large Korean firm, the Samsung Electronics Company, three main claims can be followed. First, territorial sources of learning influence the way in which the firm makes use of space/place. Second, corporate learning practices, however, are not based merely on specific localised sources or geographical proximity but on bringing together the local and the global sources by harnessing the properties of relational proximities. It reveals that firms are concerned less on specialising specific local knowledge than promoting organisational knowledge and competences by integrating a variety of knowledge distributed in and out of the boundaries of the firm. Finally, to learn and innovate in a continual basis, firms would attempt to combine codified knowledge with tacit knowledge.

This paper aims to explore the viability of a rural-industrial complex neighbouring in the metropolitan area and suggest policy implications for the restructuring of the rural industrial complex. In particular, the paper focuses on the location and management practices of the firms operating in the industrial complex. Research shows that the key elements of the viability of the rural industrial complex in Koryung-Gun are the geographical and relational proximities to the metropolitan city of Daegu and the decentralization of urban industries towards rural areas neighbouring in the large city as a result of the deterioration of location conditions in the large city. It is revealed that the major pull factors of location are 'availability of cheap industrial sites', 'agglomeration in a specialized industry' and 'proximity to major customers and suppliers' rather than 'availability of labour pool'. However, it shows that 'weak university-industry linkages' and 'insufficiency of cooperation culture' are the major limitations to attracting firms. In the context of pub1ic policy, the author argues that the restructuring of the rural industrial complex should be sought to promote social infrastructures centered on networks and learning rather than firm centered financial and tax incentives.
