  • Unknowingly, the relationship between IT departments and their internal customers becomes that of client-supplier based on the mechanisms of marketing and competition. In addition, due to enhanced focus on the customer in the planning, development, and delivery of information service, IT service management(ITSM) has become increasingly important. These days IT management is focusing particularly on the 'de-facto' standard ITIL (IT Infrastructure Library) for implementing ITSM. It is linked as a part of CobiT’s 'deliver and support' domain, which is a framework of IT governance, and ISO/IEC 20000 is a unique international certification standards on the ITSM. This paper proposes the strategy and procedure for ITSM implementation based on ITIL with consideration of IT governance structure for manufacturing industries. It also presents a case study to share the lessons learned and results of an ITSM project.

  • This paper presents a case history of a geosynthetics-reinforced segmental retaining wall, which collapsed during a sever rainfall immediately after the completion of the wall construction. In an attempt to identify possible causes for the collapse, a comprehensive investigation was carried out including physical and strength tests on the backfill, stability analyses on the as-built design based on the current design approaches, and slope stability analyses with pore pressure consideration. The investigation revealed that the inappropriate as-built design and the bad-quality backfill were mainly responsible for the collapse. This paper describes the site condition including wall design, details of the results of investigation and finally, lessons learned. Practical significance of the findings from this study is also discussed.

  • Although the strategies and experiences of GIS leading countries are considered for the implementation of NGIS-Development in Korea, the western european nations cases are not analysed. Based on this study focused on German approaches to establish and implement the construction of national geospatial data framework. The goals, construction strategies and contexts of german national framework data, it called authoritative topographic-cartographic information system(ATKIS) in germany, are presented in detail. As a result, some lessons are suggested that can be learned by german approaches. Because we are now standing on the phase of "A Second Master Plan for National Geographic Information System", the german approach can be very for the development of the national framework database in Korea.

  • Terrace deposits are often encountered in portal areas and tunnels with low overburden. They are challenging to excavate considering their great mechanical and spatial heterogeneity and a very high stiffness contrast within the ground. Terrace deposits are difficult to characterize, considering that samples for laboratory testing are almost unfeasible to obtain, and laboratory tests may not be representative due to scale effects. This paper presents the approach taken for their characterization during the design stage and their posterior validation performed during construction. Lessons learned from several tunnels excavated on terrace deposits on the Bogota-Villavicencio road (central-east Colombia), suggest that based on numerical simulations, laboratory testing and tunnel system behaviour monitoring, an observational approach allows engineers to optimize the excavation and support methods for the encountered ground conditions, resulting in a more economic and safe construction.

  • Toxicity is usually investigated using a set of standardized animal-based studies which, unfortunately, fail to detect all compounds that induce human adverse events and do not provide detailed mechanistic information of observed toxicity. As an alternative to conventional toxicology, toxicogenomics takes advantage of currently advanced technologies in genomics, proteomics, metabolomics, and bioinformatics to gain a molecular level understanding of toxicity and to enhance the predictive power of toxicity testing in drug development and risk/safety assessment. In addition, there has been a renewed interest, particularly in various government agencies, to prioritize and/or supplement animal testing with a battery of mechanistically informative in vitro assays. This article provides a brief summary of the issues, challenges and lessons learned in these fields and discuss the ways forward to further advance toxicology using these technologies.

  • An overview of developments important in the future of animal breeding is discussed. Examples from the application of quantitative genetic principles to selection in chickens and mice are given. Lessons to be learned from these species are that selection for production traits in livestock must also consider selection for reproduction and other fitness-related traits and inbreeding should be minimized. Short-term selection benefits of best linear unbiased predictor methodology must be weighed against long-term risks of increased rate of inbreeding. Different options have been developed to minimize inbreeding rates while maximizing selection response. Development of molecular genetic methods to search for quantitative trait loci provides the opportunity for incorporating marker-assisted selection and introgression as new tools for increasing efficiency of genetic improvement. Theoretical and computer simulation studies indicate that these methods hold great promise once genotyping costs are reduced to make the technology economically feasible. Cloning and transgenesis are not likely to contribute significantly to genetic improvement of livestock production in the near future.
