  • A regularization method based on the Duvaut-Lions viscoplastic scheme for plastic-damage and continuum damage models, which provides mesh-independent and well-posed solutions in nonlinear earthquake analysis of concrete dams, is presented. A plastic-damage model regularized using the proposed rate-dependent viscosity method and its original rate-independent version are used for the earthquake damage analysis of a concrete dam to analyze the effect of the regualarization and mesh. The computational analysis shows that the regularized plastic-damage model gives well-posed solutions regardless mesh size and arrangement, while the rate-independent counterpart produces mesh-dependent ill-posed results.

  • Korean academic societies in science and technology are trying to improve the prestige and quality of their journals by enlisting them in international citation databases. In order to be enlisted in international citation databases, a journal should be managed and maintained according to the policies of organizations operating citation databases. In particular, a journal should have an effective on-line publishing process including fair and transparent peer-review. KISTI studied the systematical necessary element so that the domestic journal could receive the evaluation for the international index DB record. Based on this, KISTI designed the Article Contribution Management System(ACOMS) Ver. 4.0 including the academic journal homepage and completed the english ACOMS development in 2010. Presently the english ACOMS promotes the continued facility improvement in 2012 in order to be reborn as the international journal manuscript submission/review and electronic publishing system. And it is managed about the academic journal of 49 kinds including JICCE academic journal. Therefore, this paper suggests utilizing english ACOMS as a way for JICCE journal to enlist their journals in international citation database.

  • The production of hyper-realistic digital rendering images has been available due to radical improvements of recent digital rendering and CGI (Computer-Generated Imagery) software technologies. The photorealism of digital architectural rendering images requires further studies and discussions in that architectural visualization becomes a foundation of other fields using digital rendering technology, such as movies, games, and VR industry. The principles for achieving photorealism on digital architectural rendering images were re-defined and detailed elements were analyzed through theoretical analysis of the former studies. Four principles were drawn from the architectural rendering images produced by newly-developed technologies: physically-accurate lighting calculations, accurate object geometry representation, realistic material and texture, and characteristics of photography. The sub-elements of those four principles are categorized into either essential or selective for photorealistic imagery and the randomness of the selective elements could explain the variety of photorealistic architectural rendering styles.

  • This study "The advance Study of human resource development Program Object for community Peoples in Information Society." that is too much important in Information society and IMF times. Human resource development is the process by which a community insures that it has the right number and kinds of peoples, in the right places at the right time, doing the things for which they are economically most useful. In the IMF season, an ever increasing number of cooperations are appointing executive level positions responsible for the re-enpoloyment, advancement, development of teaching, and growth of human resources. As a result, the field is being viewed as an important strategic approach to improved productivity efficiency and profitability in information society. Also, human resource development is a dynamic and evolving field in the world business. Industrial society organizations consist of three types of resources that machines, financial and human but, today have resource of organization that Knowledge, information and idea all include human. Human resource development factors will be consisted of that individual development, career development, motivation, Image making, Orignal idea development orientation and education and management time.ment time.

  • This research attempts to explore the competitive advantage of the Busan New Port based on the comparative analysis against the major ports. The competitive environment of the global shipping business poses a variety of challenges for the port authorities. Pursuing the hub position in the Northeast Asia, Busan new port needs an in-depth competitive analysis against the major ports in Singapore and China. This research proposes the strategies to exploit the locational advantage of the port while upgrading the operational efficiency. The recent development of the information technology suggests a viable solution for the Busan port.

  • 모델에 근거한 감지시스템(Model-based Monitoring System, MBM)은 생산성과 생산량을 증대 시켜줄 수 있는 방법으로 생각되어 왔다. 그러나 이러한 MBM시스템의 성능이 기대에 못 미치는 상황이 종종 발생하기도 했는데 실패의 한가지 원인은 MBM 시스템이 적절히 설계되지 못한 점에 있었다. 상태변수, 입력 및 파라미터의 추정에 관한 많은 이론적인 연구가 이루어졌지만 MBM 방식을 실제 생산공정에 적용하기 위한 설계과정에 대한 연구는 거의 없는 상황이다. 본 글에서는 MBM 시스템의 성능에 영향을 미치는 요소를 조사하고 이를 토대로 MBM 시스템의 정성적인 설계과정을 전개해 보았다. 특히 그 중에서도 MBM 시스템을 위한 감지모델의 선택에 대한 집중적으로 기술하였다. 한가지 중요한 문제점으로서 감지방식의 설계가 기계시스템의 수학적모델을 토대로 이루어져 왔는데 이 모델은 종종 감지의 관점에서 보았을 때 주요 요소를 생략하거나 또는 불필요한 요소가 포함되어질 수 있다는 것이다.
