In this study, the present condition of 8 Open APIs for books, such as Naver, Daum, Aladdin, Amazon, Google, KERIS, LibraryThing, and OCLC, were compared and analyzed. In addition, the bibliographic records of 167 samples of visible 'light & paraphotic' (DDC 535) classifications were selected from the bibliographic records of the library of C university, and the effectiveness of the Open APIs were compared and analyzed. On the basis of the results of this analysis, 12 Open API application models, which were judged to be useful in expanding the function of the access point of the bibliographic records and enhancing the library catalog using Open API, were experimentally implemented. Various methods of augmenting access points of bibliographic records and expanded library catalogue were investigated using the unique identifier described in the KORMARC fields of 001, 010, 012, 020, 035, 246, 505, 520, 850, 856 for the integrated format for bibliographic data, and Open API. Finally, using Open API for the brief display and detailed display screen as a result of search of the OPAC of the sample bibliographic records, the devices for the expanding library catalog were implemented as examples.

Recently, the application area of an embedded software become larger and larger rapidly due to the development of the wire and wireless communication, the expansion of the digital information device and the convergence of the digital devices and emphasize the effort of the development of more complete software. As a consequence, the importance of the software test process was raised to discover the defects of the software early and improve the quality of an embedded software. However there was no test process model for applying the embedded software which is required the highly precision and the real-time process. In this paper, therefore, we propose the design procedure and case study for the test maturity model of an embedded software(Emb-TMM) which reflects the characteristics of the embedded software and test process. for this, we suggest the three category of the proposed procedure which consists of the selection of the reference model and the derivation of the area, the categorization of the area level, and design model. Then we suggest the case study how the proposed procedure can be applied to the development of an embedded software actually.

According to the development and expansion of software and hardware about recent information technologies(IT), disabled persons in using IT seem to feel more information gap. Devices for IT are important tools for users including disabled persons to communicate with each other and get information. Although the Korea faces ageing society rapidly, products for disabled persons are seldom shown in time for use. As getting older especially, one of the body function disorders is visual disturbance. There are tools, braille lettering, for disabled persons with visual disturbance to communicate or get information from book. Compared to general books, however, braille lettering book is lack of including all of information of our society. Therefore, in this paper, we implement and show an embedded system for disabled person with visual disturbance to get information by scanning text, extγacting characters and converting the text to speech automatically.

Magnetic Resonance Imaging (MRI) scanner is the device to draw an image of conditions and the spread of various tissue in the body. It is used by making the patient into rounded superconductor and using high frequency which cause resonances. It uses superconduction magnet and high frequency that is non-ionizing radiation so can acquire biochemical, physical, and functional information of tissue. It is also very useful because it can scan tomography from many different angles to diagnose disease of a nervous system, the heart, and a skeletal structure. It also has advantages of that there is no risk of radiation exposure and the ability of observation on organizations such as brains, livers and the spinal cord of people. Since these features, the rate of use has been increased accordingly more considerations of the security are required when it plans. The weight of devices and the cover problem of the strong magnetic field which is occurred by magnetic resonance at the time of diagnosis can cause very important structure problems and architectural condition. That also the recent tendency which needs stronger equipment means that planning of the MRI unit should generally aim at purposing of the proximity for the device maintenance and up-grade and of further expansion. However there are not enough studies and data on the magnet resonance imaging in domestic hospitals. According to these reasons, this study has an object of indicating basic data on MRI unit plan standard and alternative proposals.

The digital technology that has brought about the information revolution acts as the causes of multi-faceted socio-cultural phenomena. The spread of the digital environment and the popularity of the digital devices accelerate the phenomenon or the fusion of culture and technology, and such a phenomenon is no exception in the fashion design. Namely, the combination of fashion design and digital-based technology draws more and more attention; Not only the technology is simply applied to the fashion design, but also it is used as an emotional tool to enhance consumers' satisfaction, while some designs and marketing cases stimulating consumers' emotion are highlighted importantly. This study was aimed at surveying and analyzing the contemporary fashion using the digital technology and thereupon, assessing the characteristics of the emotional representations of technology as well as their aesthetic values. To this end, the theory of 'science of emotion and sensibility' was applied to divide the characteristics of emotional technological expressions in the contemporary fashion into immateriality, non-boundary, multi-media and interaction, while the aesthetic values of the emotional technology immanent in the contemporary fashion were categorized into communication & participation, conceptual configuration, physical expansion and variable movement. This study analyzed uses of technology for human emotion and sensibility shown in not only collections but also communication media and exhibition spaces and thereby, suggested the direction for our fashion industry to fulfill consumers' changing needs and advance further.

Many economists and policymakers regard the ratio of R&D investment to GNP to be a good indicator of a nation's technological capabilities. Consequently, their major policy recommendation to promote technological development is a rapid expansion in R&D investment. However, a low R&D ratio does not necessarily mean less efforts at technological advancement since the composition of technologies to be developed varies depending upon the stage of economic development. Technology policy to improve the international competitiveness of domestic industries should be based on the stage of economic development and present technological status rather than on a simple comparison with advanced countries. At Korea's stage of development, maximizing the efficiency of R&D investment is more important than enlarging the size of the investment. Strategic alliances between domestic firms and foreign enterprises should be encouraged to save time and costs involved in acquiring new technologies and learning how to use them. The government should establish institutional devices to stimulate private enterprises to internationalize their business activities such as R&D, production, and marketing. The government should also promote the development of domestic and international R&D networks, which can serve as the infrastructure for technological innovations.

A previous study evaluated the seismic response of typical multi-span simply supported (MSSS) and multi-span continuous (MSC) steel-girder bridges in the central and southeastern United States. The results showed that the bridges were vulnerable to damage resulting from impact between decks, and large ductility demands on nonductile columns. Furthermore, fixed and expansion bearings were likely to fail during strong ground motion. In this paper, several retrofit measures to improve the seismic performance of typical multi-span simply supported and multi-span continuous steel girder bridges are evaluated, including the use of elastomeric bearings, lead-rubber bearings, and restrainer cables. It is determined that iead-rubber bearings are the most effective retrofit measure for reducing the seismic vulnerability of typical bridges. While isolation provided by elastomeric bearings limits the forces into the columns, the added flexibility results in pounding between decks in the MSSS steel-girder bridge. Restrainer cables, which are becoming a common retrofit measure, are only moderately effective in reducing the seismic vulnerability of MSSS and MSC steel girder bridges.
