The goal of supply chain integration is to improve the effectiveness and efficiency of supply chain for creating customer values. Supply chain integration can be classified into IT integration and structural integration. Also, structural integration can be collapsed into three dimensions: internal, supplier and customer integration. In this study, we investigate the relevance between customer value and supply chain integration. To explore the current study, we collected from 73 Korean firms. The results are as follows: First, customer value has a positively significant effect on IT integration. Second, customer value influences on customer integration but does not has an effect on internal and supplier integration. Third, IT integration improve internal, supplier and customer integration. Finally, each of structural integration positively influences firm performance. These results indicated that declaration of customer value is important factor in supply chain integration.

This study aims to develop an integration performance measurement model for each stage of information systems integration. In order to achieve the purpose of the research, first of all, the concepts of IS integration or consolidation are analyzed through theoretical and practical reviews. Also, a number of important studies of domestic and overseas cases about the stage models of IS integration or consolidation are critically reviewed. Second, we proposed three step stage model of is integration, Physical Integration stage, Application Integration stage, Service Integration stage, and Also proposed the performance measurement model for each stage of information systems integration. Third, especially in case of performance indicators and performance measurement methodology for physical integration stage are illustratively proposed, based upon the case of NCIA (National Computing Integration Agency) in Korea. This study provides the theoretical basis for reasonably deriving the stage model and performance measurement model for each stage of Information Systems Integration, and they are validating through investigating domestic and foreign practices. The results of this study are very likely to contribute to presenting the practical guideline for desirably implementing is integration or IS consolidation.

These days, firms are focusing on the improvement of relationships with business partners. The supply chain integrations are taking critical role in improving the relationships with business partners. In accordance with the development of the IT technology, it became possible for firms not only to integrate inner parts of the organization, but also to integrate the company with other organizations in the supply chain, which is open system. Therefore, in e-Biz environments, it is imperative for firms to strengthen the core capacity through the supply chain integration, and to precisely determine the components of the determinants of e-Business integration which impact the firm performance. This study analyzed determinants that have impacts on business integration in IT capacity perspectives in competetive environments. We analyzed 163 domestic companies to find out many significant suggestive points. First, IT management capacity, process innovation capacity are adopted as determinants of differentiation and competetive edges against competing firms. Second, it is analyzed that the more the companies are in intensified competetive environment, the more likley that the innovation capacity and partner management capacity become the determinants of the business integration of the companies and that they pursue new market development strategy. Third, it is analyzed that the more the companies are in high demand fluctuation, the more likley that the innovation capacity becomes the determinants of the business integration of the companies, and that they pursue new market development strategy and operation efficiency strategy. Last, it is analyzed that the more the companies are Technology dependent, the more likely that IT management capacity and process innovation capacity become the determinants of business integration, and that they pursue new market development strategy and operation efficiency strategy. These results provide us the foundation that the determinants that we have analyzed can impact the supply chain integration strategies which take into account the competetive environments.

In land navigation applications, two kinds of GPS/DR integration schemes are commonly used; the loosely-coupled integration scheme and the tightly-coupled one. The loosely-coupled integration filter has a simple structure and is easy to implement. When the number of visible satellites is insufficient, however, it cannot calibrate the errors of the DR sensors. On the contrary the tigthly-coupled integration filter can sup-press the growth of the error in the DR output even when the visibility is poor. However, it has larger com-putation load due to the state dimension and is inconsistent because of the variation in the measurement dimension. This paper presents a GPS/DR integration scheme with dual integration mode. During when the number of visible satellites is sufficient, the proposed scheme operates in a loosely-coupled integration mode. When the visibility becomes poor, it is switched into a tightly-coupled integration mode. Consequently, the pro-posed scheme can calibrate the DR sensors even when the visibility is poor. In addition, its computation time remains constant even if the number of visible satellites increases. Field experiment results show that the performance of the proposed integration method is almost similar to that of the tightly-coupled one.

The development and integration of Enterprise Resource Planning (ERP) systems have consistently attracted attention from software engineering researchers. Many studies have examined the factors that influence successful ERP integration, while others have focused on introducing integration models that address issues and challenges that affect the successful integration of ERP. However, it is crucial to recognize that the key player in successful integration is the individual involved. This paper aims to investigate how individuals based on departmental attachments and experiences have viewed the factors that affected the success of ERP integration. A case study was conducted at one large organization namely Umm Al Qura University, Saudi Arabia. Five departments were involved namely: Financial management, purchasing management, warehouse management, human resources management, and the Deanship of Information Technology. The results of 78 participants were collected and analyzed. Furthermore, it was different how individuals from different departments involved in the ERP integration viewed the factors that affected the success of integration. In addition, it was noticed that individuals with different experiences have various views on the factors. Moreover, it was evident that departmental attachments and individual experience might play a role in the successful integration of ERP.

Recently, Mergers and Acquisitions (M&A) have become increasingly popular in the last few decades, and overseas' M&A are particularly increasing to sharpen corporate competitiveness on a global scale. Previous studies showed that one of the main reasons attributes to failures of mergers was the lack of attention to merging information systems. In recent years, both academy and industry have more focused on Post-Merger Integration (PMI) and the integration of information systems (IS) between two companies is one of the critical success factors of corporate. This paper focused on Post-Merger IT (Information Technology) Integration Methodology of Cross-Border M&A. We followed a single-site qualitative case study method in order to investigate the type of phenomenon in M&A's natural setting. Moreover, we examined a typical energy and power company case in order-based industry, so that other industry players may have different results to determine post-merger IT integration method and scope.

In the merged organization, the efforts of integration such as various PMI activities, etc. are exerted and the performance of PMI can be judged by evaluating the effectiveness of an organization. In this paper, the empirical analysis was conducted to see what effects of 'planned PMI activities' and 'voluntary integration efforts' have on the effectiveness of an organization which is 'Organizational Commitment', 'Job Satisfaction', 'Emotional Integration' and 'Shared Value Recognition'. The survey was made on the employees of LH, which is a representative case of public corporation advancement, and SPSS 17.0 and AMOS 17 were used for the analysis. As a result of the analysis of a structural equation model, it indicated that both 'planned PMI activities' and 'voluntary integration efforts' have direct influence on 4 indices of effectiveness of an organization respectively. In particular, it was found that 'planned PMI activities' affects 'Shared Value Recognition' the most and 'voluntary integration efforts' has the largest effect on 'Emotional Integration'. Through this study, it was verified that voluntary integration efforts of members as well as the planed formal PMI activities are also very important factor of effect on the integration performance of an organization.

Korean administrative jurisdiction has changed from separation to integration system, without definite raison d'etre from the effectiveness dimension. It partially comes from the fact that the top priority of most existing documents has given to the behavioral patterns of key variables during specific time periods. As an alternative approach, this study focuses on dynamic analysis on the long-term structural patterns related to urban-rural integration issues. Specifically, it pays attention to unique experiences between two neighboring administrative authorities, namely Cheongju and Cheongwon, all of which have repeated exceptional confrontations between pros and cons over almost two decades. From the theoretical perspectives, this observes structural similarities and differences between separation and integration approaches and compares individual feedback loops in order to examine urban-rural integration effectiveness. Structurally, if the integrated local authority adopts systematic management and balanced territorial development principles, it would gain the highest positive effect of urban-rural integration. After scenario buildings, it analyzes administrative integration dynamics between Cheongju and Cheongwon, highlighting geo-political conditions, key issues, and implementation plans between two administrative authorities. It expects that the integrated jurisdiction as a whole would increase the urban attractiveness as it can facilitate territorial development plans from macro-level. Furthermore, if the integrated authority keeps balanced territorial principles, which would be well reflected in the mutual agreement between two administrative units, it would also guarantee the increased urban attractiveness in the integrated jurisdiction. Nonetheless, compared to Cheongwon, which might be wider open to the location of NIMBY facilities, it would be more difficult for Cheongju to pay attention to territorial development confined to its original jurisdiction in the short run.
