China has gone through rapid economic growth due to transitional economies since 1978. In particular, Chinese transitional economies has led to fundamental changes in firms' activities under the socialist system. Nevertheless, Chinese firms have formed new industrial production organizations and spatial orders by sustaining personal networks based on existing traditional firm practice, which is called 'guanxi'. Therefore, the main purpose of this research is to identify the influence of personal networks, guanxi, on the business activities of Chinese firms by investigating the formation of guanxi mechanism. The main characteristics of guanxi represented in inter-firm relations are as follows. First, guanxi has played a role in facilitating inter-firm relations and business activities, because it has an inter-debt relations based on inter-reciprocal relations between firms. Second, Chinese firms has depended on posteriori guanxi rather than inherent guanxi by the internalization of personal networks through 'guanxi communicators'.Third, guanxi between firms and local government in extra-firm relations has been established to minimize risks from unstable legal regulations.

Purpose: This study was performed to develop the electronic textbook (CD-rom title) about preclinical practice of oral and maxillofacial radiology, using multimedia technology with interactive environment. Materials and Methods: After comparing the three authoring methods of multimedia, i.e. programming language, multimedia authoring tool and web authoring tool, we determined the web authoring tool as an authoring method of our electronic textbook. Intel Pentium II 350 MHz IBM-compatible personal computer with 128 Megabyte RAM, Umax Powerlook flatbed scanner with transparency unit, Olympus Camedia l400L digital camera, ESS 1686 sound card, Sony 8 mm Handycam, PC Vision 97 pro capture board, Namo web editor 3.0, Photoshop 3.0, ThumbNailer, RealPlayer 7 basic and RealProducer G2 were used for creating the text document, diagram, figure, X-ray image, video and sound files. We made use of javascripts for tree menu structure, moving text bar, link button and spread list menu and image map etc. After creating all files and hyperlinking them, we burned out the CD-rom title with all of the above multimedia data, Netscape communicator and plug in program as a prototype. Results and Conclusions : We developed the dental radiology electronic textbook which has 9 chapters and consists of 155 text documents, 26 figures, 150 X-ray image files, 20 video files, 20 sound files and 50 questions with answers. We expect that this CD-rom title can be used at the intranet and internet environments and continuous updates will be performed easily.

By analyzing abstract book cover design, this study aims to examine the applicability of the semiotic methodology of Roland Barthes and to conduct a preference survey of how people would accept it. The selected books for the study are and published in Openbooks publishing company to mark the 30^th anniversary of the opening. The research results are as follows. First, it was confirmed that Roland Barthes' semiotic approach is a suitable tool for identifying the symbolic phenomena of visual elements that constitute abstract book cover design. Second, people were well informed of what the abstract form of design conveys, but they showed personal differences in preference, making it difficult to achieve clear results. This study, together with the importance of the internal meaning that appears in the book cover design, gives graphic designers an indication that interaction between the communicator and the acceptor should be sought.
