The GIS has grown in its quantity as local authorities established the urban information system for better city administration, civilian services and decision-making support services. Recently, local authorities have expressed much interest on the introduction of ubiquitous technology to improve citizens' safety and convenience. This has become the drive behind the construction of ubiquitous city(u-City). Construction of a u-City requires the multitude of information and telecommunication networks and digital contents; the existing information resources need to be put to use in entirety for that end. In that regard, the integration of GIS established and currently operated by local authorities needs to be strategically promoted. This study intends to propose GIS integration strategies in various aspects for the future u-City and directions for the development of urban information systems in the coming of the Ubiquitous Age.

When we integrate schema of distributed local databases, we mean entity integration as central concept of schema integration, and semantic of entity affects several factors. Thus the schema integration in distributed database environment starts from definition of domain relation among entity types of local schemas. Moreover, the domain relation defined by designer needs some works for confidence and validation of schema integration system. But this work was not presented in previous integration system. In this paper, we define object oriented integration for schema integration of local databases in distributed system environment, present models to verify validation on its integration, and implement the validation system.

The youth with developmental disorders have substantial limitations in intellectual capacities and adaptive behaviors. For them to live independently as members of the local society after they graduate from high school, a continuous education in consideration of individual and environmental differences should be accompanied. The computer education can be a useful tool in their integration into the local society by 'Expansion of universality and the equality of education'. Particularly, the computer education as a transitional educational process can be of practical help for them to sustain independent and daily lives in the adult world. In this regard, this writing reviews 1) the integration into the local society of the youth with developmental disorders and the transitional education, 2) the significance and meaning of computer education for the youth with developmental disorders, and 3) the status of computer education for the youth with developmental disorders to present improvements for the computer education of the youth with development disorders.

The measurement of the key product quality index plays an important role in improving the production efficiency and ensuring the safety of the enterprise. Since the actual working conditions and parameters will inevitably change to some extent with time, such as drift of working point, wear of equipment and temperature change, etc., these will lead to the degradation of the quality variable prediction model. To deal with this problem, the selective integrated moving windows based principal component regression (SIMV-PCR) is proposed in this study. In the algorithm of traditional moving window, only the latest local process information is used, and the global process information will not be enough. In order to make full use of the process information contained in the past windows, a set of local models with differences are selected through hypothesis testing theory. The significance levels of both T - test and χ² - test are used to judge whether there is identity between two local models. Then the models are integrated by Bayesian quality estimation to improve the accuracy of quality variable prediction. The effectiveness of the proposed adaptive soft measurement method is verified by a numerical example and a practical industrial process.

A distributed DBMS integrates local schemas that are independently designed, maintained, and managed by different users at each site providing a global virtual schema. This global schema supports users at a specific site to transparently utilize local database at different sites. The security features of the local schema should also not be changed in the global schema integrating security features of each local schema. Researches on the integration of security features into local schema in distributed DBMS environment, however, are very rate. This pater using the multilevel secure object-oriented database model(as the model for the definition of a local schema in distributed environment) which is an extension of the object-oriented models. It also suggests eight integration methods that can maintain the security features of local schemas. The eight methods are classified by the object classes and by relationships among them.

We propose an enhanced version of the local binary pattern (LBP) operator for texture extraction in images in the context of image retrieval. The novelty of our proposal is based on the observation that the LBP exploits only the lowest kind of local information through the global histogram. However, such global Histograms reflect only the statistical distribution of the various LBP codes in the image. The block based LBP, which uses local histograms of the LBP, was one of few tentative to catch higher level textural information. We believe that important local and useful information in between the two levels is just ignored by the two schemas. The newly developed method: gradual locality integration of binary patterns (GLIBP) is a novel attempt to catch as much local information as possible, in a gradual fashion. Indeed, GLIBP aggregates the texture features present in grayscale images extracted by LBP through a complex structure. The used framework is comprised of a multitude of ellipse-shaped regions that are arranged in circular-concentric forms of increasing size. The framework of ellipses is in fact derived from a simple parameterized generator. In addition, the elliptic forms allow targeting texture directionality, which is a very useful property in texture characterization. In addition, the general framework of ellipses allows for taking into account the spatial information (specifically rotation). The effectiveness of GLIBP was investigated on the Corel-1K (Wang) dataset. It was also compared to published works including the very effective DLEP. Results show significant higher or comparable performance of GLIBP with regard to the other methods, which qualifies it as a good tool for scene images retrieval.

As applications of GIS technology have grown in local governments, the wider and integrated use of spatial information is demanded more than before. Particularly because 70-80% of administrative information in local governments are related spatial, it becomes a key issue to connect and integrate non-spatial information with spatial information for more advanced use of GIS applications in local governments. The purpose of this study is to establish an advanced Implementation model by analyzing obstacles in existing GIS applications and suggesting implementation strategies. The strategy, as an important part of the model, includes efficient information sharing, establishment of commonly usable GIS Database, architectural improvement for Enterprise GIS in terms of database and system implementation, standardization far the model, and establishment of spatial infrastructure in the local governments. The study concludes that administrative collaboration in a horizontal and vertical perspective has a highest priority for the implementation of the model.

The globalization of business is making it more important than ever to understand how international human resource can be utilized more competitively. This study explores how the international human resource strategies between global integration and local responsiveness affects the company's competitive advantage. The findings for global integration strategy suggest that when a subsidiary is highly dependent on the parent company's resources and the findings for local responsiveness suggest that when a subsidiary is highly dependant on the host country's resources and institution. This study proposes competitive advantage by the global integration strategy and local responsiveness strategy. The effects of IHRM to create value for company's core competence was analyzed. Two IHRM strategic choices will affect the different competences such as integration and localization abilities. This paper also suggests the two kinds of core competences of IHRM strategies how impact on company's performance.

Due to the evolution of computer systems and the proliferation of Internet, numerous information resources have been constructed. The deluge of information makes the need to integrate information, which are distributed on the internet and are handled in heterogeneous systems. Recently, most of the XML -based information integration systems use XML DTD(Document Type Definition) for describing integrated global schema. However, DTD has some limitations in modeling local information resources such as datatypes. Although W3C's XML Schema is more flexible and powerful than XML DTD in specifying integrated global schema, it has more complex problems in resolving conflicts than using DTD. In this paper, we provide a taxonomy of conflict problems in integration information resources using XML Schema, and propose conflict resolution mechanism using XQuery.
