Negative space in the discipline of art defines the space around and between the subject of an image. The use of negative space is an element of artistic composition, since it is occasionally used to artistic effect as the "real" subject of an image. In painting, it is a technique that negatively touches the background of an object to be expressed, so that it gives a feeling of unique texture and silhouette by touching unnecessary parts while leaving necessary parts. As in art, negative space in a design can also be useful to identify an image of infeasible design ranges with a straightforward view. Similarity between two disciplines leads to the introduction of the negative space concept for design space exploration. A rough design space exploration using statistics and visual analytics may support more efficient decision-making, and can provide meaningful insights into the direction of early-phase system design. For this, the approach guarantees dynamic interactions between visualized information and human cognitive systems. Visual analytics is useful to summarize complex and large-scale data. It is useful for identifying feasible design spaces, as well as for avoiding infeasible spaces or highly risky spaces. This paper investigates the possible use of the negative space concept by using an application example.

In this paper, we design and implement a system for managing domain specific thesauri, where object-oriented paradigm is applied to thesaurus construction, concept browsing and query-based reference. This system provides an objected-oriented mechanism to assist domain experts in constructing thesauri; it determines a considerable part of relationship degrees between terms by inheritance and supplies domain experts with information available from a thesaurus being constructed This information is especially useful to enforce consistency between the hierarchies of a thesaurus, each constructed by different experts in different sites through cooperation. It may minimize the burden of domain eIn this paper, we design and implement a system for managing domain specific thesauri, where object oriented paradigm is applied to thesaurus construction, concept browsing and query based reference. This system provides an objected mechanism to assist domain experts in constructing thesauri: it determines a considerable part of relationship degrees between terms by inheritance and supplies domain experts with information available from a thesaurus being constructed. This information is especially useful to enforce consistency between the hierarchies of a thesaurus, each constructed by different experts in different sites through cooperation. It may minimize the burden of domain experts caused from the exhaustive specification of individual relationship. This system also provides an abstracted browsing and a query based reference, which allow users to easily verify thesaurus terms before they are used in usual boolean queries. The verification is made by actively searching for them in the thesaurus. Reference queries and abstracted browsing views facilitate this searching. The facility is indispensable especially when precision counts for much.

This study suggests external knowledge search as a way of creating knowledge and efforts for reaching out to the innovation and examines the relationship between innovation speed and the breadth and depth of external knowledge search. As a part of efforts to overcome the limitations of the routines of external knowledge search in the domestic market, the efforts of a firm to enter the foreign market have been examined with a moderate effect. Although previous research focused on exploration of external knowledge that is mostly effected in single country or similar industry, this study expands it by introducing the concept of market expansion and empirically inspect the interaction effect. 818 valid samples used in this study are based on the innovation survey published by STEPI and empirical results are as follows. First, the breadth and depth of external knowledge search have a positive impact on innovation speed. Second, export performance as the effect of expanding the market has a moderating effect on the speed of innovation. Third, younger companies prefer various networks while older companies prefer depth networks in order to increase the speed.

A Web-based environment has very various and heterogeneous users. The emphasis on their individual characteristics may make it hard to reach the general understanding of how they seek and use information on the Web. The purpose of this study is to find common patterns in information seeking behavior on the Web by analyzing a series of cognitive movement of users in interaction with the Web. Based on Dervin's concept and Timeline interview methodology, this study collected 37 Web experience descriptions from 21 respondents, which consisted of 302 steps. Findings addressed that Web information seeking behavior can be classified into seven types : Starting, Searching, Viewing/B row sing , Examining/comparing, Finding/compiling, Deciding/Acting, and Ending. Movement paths in the seven-type information seeking process showed that user's interaction with the Web was repeated and circulated at the Viewing/Browsing step and that information seeking behavior on the Web was multi-directional and non-linear.

This study suggests the way of revitalization of strategic specialized industry from the perspective of design business model. In order to revitalize the regional strategic specialized industry, it is necessary to overcome traditional production-based industry structure. For the industry's side, companies should convert their traditional production-based business perspective into market-oriented or design-oriented one. For the designer's side, they need to lead the design-centered industry structure by suggesting active design sources to industries escaping from passive design development perspective. Namely, the revitalization of strategic specialized industry can be peformed by design-based and market-oriented business execution. The formation of market-oriented industry can be accomplished by designers who do their design development works with design-business perspective and play an active role in the industry system. For the suggestion of concept mentioned above, this study conceptualized the meaning of design business, and applied the concept of it to the case study for bamboo industry of Damyang province. The case study suggests the possibility that designers are able to create higher profit through various sources such as sales royalty, production royalty etc by playing an active role for design development, industry selection, business system establishment and so on. In addition, the study implies that industries can increase the possibility of business success through design-based business execution mentioned above.

In recent years, service discovery is one of the major technologies of home networks which head for a pervasive computing environment. However, existing service discovery techniques are difficult to understand semantics, and they only provide syntactic level service matching. To solve these problems, we have designed and developed ontology for semantic service discovery. Our ontology could enrich the amount of devices and services representations with semantics, and the relation of devices and service could be efficiently described through primitive service. For representing context information of devices, we describe attributes of device including location information, device status and etc. To determine whether the developed ontology can be applied to service discovery systems, we have implemented a semantic service discovery system by extension of the existing Jini lookup service. Also, we have evaluated our ontology with associated software environment according to some experiment scenarios, and have proved the usefulness of our ontology-based semantic service discovery system.

Pub/sub system enables data users to access any necessary data without knowledge of the data producer and synchronization with the data producer. It is widely used as the middleware technology for the data-centric services. DDS (Data Distribution Service) is a standard middleware supported by the OMG (Object Management Group), one of global standardization organizations. It is considered quite useful as a standard middleware for US military services. However, it is well-known that it takes considerably long time in searching the Participants and Endpoints in the system, especially when the system is booting up. In this paper, we propose a discovery scheme to reduce the latency when the participants and Endpoints are densely distributed in a small area. We propose to modify the standard DDS discovery process in three folds. First, we integrate the Endpoint discovery process with the Participant discovery process. Second, we reduce the number of connections per participant during the discovery process by adopting the concept of successors in Distributed Hashing scheme. Third, instead of UDP, the participants are connected through TCP to exploit the reliable delivery feature of TCP. We evaluated the performance of our scheme by comparing with the standard DDS discovery process. The evaluation results show that our scheme achieves quite lower discovery latency in case that the Participants and the Endpoints are densely distributed in a local network.
