  • Mobility and cloud platform have become the dominant paradigm to develop web services dealing with huge and diverse digital contents for scientific solution or engineering application. These two trends are technically combined into mobile cloud computing environment taking beneficial points from each. The intention of this study is to design and implement a mobile cloud application for remotely sensed image fusion for the further practical geo-based mobile services. In this implementation, the system architecture consists of two parts: mobile web client and cloud application server. Mobile web client is for user interface regarding image fusion application processing and image visualization and for mobile web service of data listing and browsing. Cloud application server works on OpenStack, open source cloud platform. In this part, three server instances are generated as web server instance, tiling server instance, and fusion server instance. With metadata browsing of the processing data, image fusion by Bayesian approach is performed using functions within Orfeo Toolbox (OTB), open source remote sensing library. In addition, similarity of fused images with respect to input image set is estimated by histogram distance metrics. This result can be used as the reference criterion for user parameter choice on Bayesian image fusion. It is thought that the implementation strategy for mobile cloud application based on full open sources provides good points for a mobile service supporting specific remote sensing functions, besides image fusion schemes, by user demands to expand remote sensing application fields.

  • In domestic university libraries, the difference between the knowledge resource collection activities on campus is depending on the size of the university, and their collection is concentrated on some types of digital resources. In recent years, the main universities in developed countries has developed actively in social openness and share activities of their knowledge resources, through the OA-based institutional repository, for the purpose of image improvement and competitiveness as a knowledge production base. This study examined ways to improve the relevant regulations in order to effectively collect and systematically manage the knowledge resources from graduate school, research institutes, center for teaching and learning, e-learning center, museum, press, a variety of campus organizations, so as to enhance the role of the library as the right manager of knowledge resources on campus. To this end, this study, considering the improvement of relevant regulations, investigates the operating situation of the library regulations of 176 universities and suggests necessary improvement methods in order to facilitate the digital legal deposit and expand its scope.

  • The purpose of this study was to research instances of green library construction and recognition in order to increase awareness of green libraries. To this end, we investigated the green library's outline and green building, evaluated cases of G-SEED certified libraries, and surveyed the employees at the 16 different G-SEED certified libraries. Results showed that the employees' knowledge of green libraries and the green certification system was low, whereas their interest and needs regarding the green library concept were very high. Second, the respondents were able to recognize as a whole the factors of green library construction based on the evaluation items for G-SEED and place particular emphasis on 'recyclable resources & recycling bins.' However, only a few recognized 'water reclamation/reuse system establishment' as a green library factor. Third, the respondents largely agreed upon an evaluation of items on the suitability of G-SEED, and their ranked reasons for build a green library were preventing environmental pollution, energy-saving, environment, ecology, and indoor environmental factors. Fourth, a lack of 'awareness about the concept of the green library' was thought to most affect the awareness of difficulties in green library construction, and the respondents agreed with the need for 'library image enhancement' to better manage expectations of the green library.

  • The University's web library is a form of library that enables to deal with information about searching loaning, returning of books or data housed in it through web. With the advent of the network and multimedia following the entrance to an information-oriented society, we are experiencing a big change in how to communicate and acquire information. Massive multimedia information transmitted by image and moving picture through the network, made it possible to overstep the limit of the physical gap between information suppliers and users. Despite this important role, it is accompanied by problems such as copyright, scarcity of recognition, paralysis of infra, technical matters and reliability which demand development. In this thesis, according to the State University Evaluation Standards, search node and user interface by system used in 20 different universities possessing web-based library sites were compared are analysed. On the basis of this, an experimental user interface for web-based University libraries was produced, and various questionnaires and data leer this produced interface were collected, classified and analyzed. With the application of the results for the work above to the general search system interface of the web-based library, we proposed a new user interface that contains the following functions, such as location and loan condition of books, search frequency and steps for purchasing books inside the web library.

  • Recently, the interest and research on 360 camera and 360 image production are expanding. In this paper, we describe the feature extraction algorithm, alignment and image blending that make up the feature-based stitching system. And it deals with the theory of representative algorithm at each stage. In addition, the feature-based stitching system was implemented using OPENCV library. As a result of the implementation, the brightness of the two images is different, and it feels a sense of heterogeneity in the resulting image. We will study the proper preprocessing to adjust the brightness value to improve the accuracy and seamlessness of the feature-based stitching system.

  • X-ray cross-sectional image-based inspection technique is one of the most useful methods to inspect the brazing joints of heat exchanger. Through X-ray cross-sectional image acquisition, image processing, and defect inspection, the defects of brazing joints can be detected. This paper presents a method to judge the type of detected defects automatically, and to display them three-dimensionally. The defect type is classified as unconnected defect, void, and so on, based on location, size, and shape information of defect. Three-dimensional display which is realized using OpenGL (Open Graphics Library) will be helpful to understand the overall situation including location, size, shape of the defects in a test object.

  • This study recognizes the need for Korean university society to have to prepare for the coming of the Fourth industrial revolution era and for rapid decline in the school-age population, and presents a diagnosis of the current situation of the department of domestic library and information science. To respond to such issues, it explores the identity of the department of library and information science, and the future development direction thereof. The findings of this study reveal as of February 2020 that 36 universities offer the department of library and information science, while 18 universities abolished the department. Further, compared to 2013, 2019 saw the number of the students enrolled and full-time faculty decline by 38.5% and 13.4%, respectively. Thus, the identity and future development direction of Korea's department of library and information science were examined by dividing the issue into 5 parts. Five proposals thus were presented: First, convergence education is required at the level of academic identity. Second, at the level of law and state, the department of library and information science, it should be guaranteed that the library and information science should be promoted and that the employment should be stabilized. Third, at the level of association, the social image of the department of library and information science should be enhanced. Fourth, at the level of universities, the support for and promotion of the department of library and information science should be boosted. Fifth, at the level of the department, student-oriented education should be bolstered and the employment rate should be enhanced.
