ERP system has been spreaded from large companies to many small and medium sized companies, and it is recognized as a basic system for optimum and efficient work process. The focus is moving from manufacturing companies to various specialized companies. Once ERP system was introduced to those specialized companies, there was attempt to customize an ordinary system which used in manufacturing companies, but it was hard to take effect due to the lack of experience and an inadequate analysis of work process. Some of foreign ERP packages are possible to be constructed for some companies. However, they are originally aim at a large enterprise and it is also very difficult to construct and maintain. For this reason, small and midium sized companies are having a difficulty to construct ERP system. This study deals with the construction of ERP system for small and medium sized design engineering company and introduction of the crucial points throughout the construction and requirements for composition module and customization of each main module. Based on the findings of this study, the specialized non-manufacturing companies are expected to have efficient and practical application of ERP system when they select and customize the ERP package of manufacturing companies.

The small and medium construction companies are facing potential EHS(Environment, Health & Safety) of major accidents to cause casualties or a financial loss and increasing social responsibility. So, they have to voluntarily accomplish the EHS management system rather than passively with regard to EHS regulation. In this study, the framework of integrated EHS management system is developed based on cloud computing, and construction companies are to materialize self-regulation EHS process of construction workplace and to standardize the total EHS business process using the developed system. The proposed system also provides risk analysis, education/control and continuous improvement for EHS tasks and users can easily access the system on the web at a low price through cloud computing service. Eventually, the integrated system contributes to the managerial improvement by minimizing economic and physical loss caused by construction accidents.

Several cloned animals have been produced using somatic cell nuclear transfer (SCNT) and have interested in producing the transgenic cloned animals to date. But still its efficiency was low due to a number of reasons, such as sub-optimal culture condition, aberrant gene expression and nuclear reprogramming. The purpose of this study was to analyze gene expression pattern in in vitro fertilized (IVF) or SCNT pre-implantation embryos. IVF- or SCNT-embryos were cultured in media supplemented with different proteins (FBS and BSA) or energy sources (glucose or fructose). Blastocysts from IVF or SCNT were analyzed using semi-quantitative RT-PCR in terms of developmentor metabolic-related genes. Culture medium supplemented different proteins or energy sources had affected on the expression of developmental or metabolic genes in the SCNT blastocysts.

Remarkably improvements have occurred recently in the maintenance management of physical assets and productive systems, so that less wastages of energy and resources occur. The technology of maintenance is about finding and applying cost-effective ways of avoiding or overcoming performance deterioration. Maintenance is thus a vital support function in business, especially as increasingly large investments are being required in physical assets. TPM(Total Productive Maintenance) focuses on optimizing planning scheduling. Availability, performance and quality rate are other factors that affect productivity. Especially there are some losses that affect the overall equipment effectiveness(OEE). These losses lead to low values of OEE, which provides an indication of how effective the production precess is. This study explores the ways in which Korean small and medium manufacturing industries can improve OEE.

Human fibroblasts that maintain the structural integrity of connective tissues by secreting precursors of the extracellular matrix are typically cultured with serum. However, there are potential disadvantages of the use of serum including unnatural interactions between the cells and the potential for exposure to animal pathogens. To prevent the possible influence of serum on fibroblast cultures, we devised a serum-free growth method and present in vitro data that demonstrate its suitability for growing porcine fetal fibroblasts. These cells were grown under four different culture conditions: no serum (negative control), 10% fetal bovine serum (FBS, positive control), 10% knockout serum replacement (KSR) and 20% KSR in the medium. The proliferation rates and viabilities of the cells were investigated by counting the number of cells and trypan blue staining, respectively. The 10% FBS group showed the largest increase in the total number of cells (1.09 × 105 eell₃/ml). In terms of the rate of viable cells, the results from the KSR supplementation groups (20% KSR:64.7%; 10% KSR: 80.6%) were similar to those from the 10% FBS group (68.5%). Moreover, supplementation with either 10% (30 × 104 eell₃/ml) or 20% KSR (4.8 × 104 cells/ml) produced similar cell growth rates. In conclusion, although KSR supplementation produces a lower cell proliferation rate than FBS, this growth condition is more effective for obtaining an appropriate number of viable porcine fetal fibroblasts in culture. Using KSR in fibroblast culture medium is thus a viable alternative to FBS.
