Ever-developing information and communications technology has changed the ways of life from that of industrial society to the information-oriented community, and is widely used in a variety of social and economic contexts. Besides, urban problems in today's society are intricately involved so that the possibility of any reliable breakthrough may not to be likely. To work out these complicated problems as well as to understand the crux of the matter more comprehensively, ubiquitous urban planning has been laid out, and as a result attempts to reflect this system are cautiously made in metropolitan areas. However, most u-City planning, integrating uibiquitous technology, has focused on creating urban infrastructure and its services, therefore neglecting the importance of housing in urban space. Consequently, thorough u-City planning has yet to be defined in relation with urban space, and housing planning, established on the basis of the user-oriented housing environment, needs to be urgently made. Centering on the importance of housing in the construction of an improved future urban environment, this study aims to discuss the role of urban environment planning where metropolutan residents can enjoy a comfortable and convenient life. As well, this research paper seeks to focus attention on the consideration for users that is often disregarded but requires reflecting in the u-City planning.

Conventional hypermedia systems provide a simple data model based on nodes and link, and give us the limited capability in information retrieval such as browsing and navigating following the links. In this paper, we design and implement a hypermedia system (AHEAD) with enhanced data modeling and querying capability, which are strongly supported in object-oriented database technology. The AHEAD makes it possible to model the accurate data semantics and relationships in application domain, to represent useful information related to nodes and links, and to define the structure and manipulation operations of multimedia data. It also support the various querying capabilities by using modeling information.

Improving software product quality is a key to increasing user satisfaction and to achieving competitive edge. There are two approaches to assure high software product quality; development process-oriented and product-oriented. There have been many efforts for improving software quality through process certification, for example, CMM, ISO 9000 family, ISO/IEC 12207, SPICE and Bootstrap. However, a good process alone cannot guarantee good product quality. A need for the evaluation of software product quality by an independent third party is growing rapidly for several reasons. We are concerned with an application of Statistical Quality Control (SQC) to the evaluation of software product quality to obtain the efficiency of evaluation processes and the objectivity of evaluation results. Methods for selecting test cases using a random sampling approach have been discussed and methods for selecting acceptance criteria with respect to software product quality have also been suggested.

Development of digital information and internet technology causes the changes of technology environments and companies, and the variety of customer needs has been dynamically changed in terms of integrating information system with customer satisfaction. Moreover a new logistics concept is needed through the sharing information between suppliers and consumers, which maximizes the level of customers service and its flexibility by changing functional-oriented to process-oriented. In other words, Supply Chain Management (SCM) is now considered as a key aspect of business, which controls the flows of information, funds, and goods in the supply chain. Rationalization of transport-delivery system will be one of the most important issues on logistics management to the domestic companies. The companies need the effective delivery system. Especially in the case of delivery system from distribution centers to customers or vendors, it might take a long time to control the delivery system manually because it would be hard to apply the automatic vehicle routing algorithm effectively considering all the practical constraints. Thus this study develops a heuristic algorithm of automatic vehicle delivery support system in terms of grouping by short ranges of vehicle movement utilizing postal coordinates, which satisfies a variety of realistic constraints and reduces controlling time of manual operations. In addition, the performance of the algorithm developed in this study is evaluated through the case study.

Using modified melt-textured grown targets, YBa$_2$Cu$_3$O$_{7-{\delta}}$ thin films were prepared by pulsed laser deposition technique at the laser energy density from 1 J/cm$_2$ to 4 J/cm$_2$. All the films showed c-axis preferred orientations, however, a-axis outgrowths on the film surface were considerably increased with an increase of the laser energy density. To examine the origin of the a-axis outgrowth formation, the microstructures of films deposited at 2 J/cm$_2$ and 4 J/cm$_2$ were investigated using X-ray diffraction, transmission electron microscopy, and high-resolution electron microscopy. It was shown that a significant number of Y$_2$O$_3$ inclusions were formed during the growth of c-axis oriented films at 4 J/cm$_2$. These inclusions formed nucleation sites for the a-axis outgrowths. It is considered that, due to the unstable growth conditions with a high flux density of incident vapor species and the strain induced by the surrounding c-axis films, the Y$_2$O$_3$ inclusions would prefer the nucleation of α-axis grains.
