Purpose: This study examined the importance and satisfaction of consumer's perception of the information delivery format of products and services required and recommended by KS A ISO / IEC Guide 13: 2003 and KS A ISO / IEC Guide 37: 2003. Methods: In this study, the importance and satisfaction of clarity, principles of information transfer, how to use expressions and technical terms, and technical terms, warning signs, and durability were investigated. Results: The t-test analysis of the importance and satisfaction of the Writing Rules of the product user guide showed that all items had statistically significant differences. The importance of the writing rules of the product user guide for the use of the product was in the order of warning signs (4.423), how to use expressions and technical terms (4.215), principles of information transfer (4.163), clarity (3.914), and finally durability (3.851). Conclusion: Among the 'explanation,' 'instruction' and 'warning' functions of the Product User Guide, the consumer uses the manual to identify the inherent dangers and misuse of the product. Besides, since the life of the product is prolonged, the Product User Guide also needs to improve the quality of the cover or paper so that it can use for a long time.

The purpose of this study is to suggest new safety technical standards to improve the safety in the incineration process. Firstly, we analyzed the major accidents occurred in the incineration process since 1996 and proposed 4 articles which is required to be added newly to the existing KOSHA GUIDE. Secondly, we also performed the HAZOP study for each study node and also suggested 3 articles. Finally, we analyzed recommendations commented for PSM reports which have been submitted from the enterprise located in Honam province since 2005 and proposed 2 articles as well. We understand that all 9 articles proposed above, should be added to the KOSHA GUIDE in order to improve the safety in the incineration process and to prevent the major fire and explosion accidents in the design stage.

The variable demand on the energy market requires a great flexibility in operating hydro turbines. However, Francis turbine operated at off-design conditions poses technical challenges related to large unsteady forces given by residual swirl and angular momentum. In order to improve the performance of a Francis turbine, the paper presents a numerical investigation of the 3D flow in the turbine at off-design conditions and discusses the influence of variable guide vane openings on the internal flow of a Francis turbine with the help of computational fluid dynamics. First, the internal flow characteristics of Francis turbine operated by varied guide vane angle at off design condition are computed and the optimal guide vane angle is obtained. Secondly, the Francis turbine is operated with guide vane number varies at the optimal guide vane angle. Finally, pressure contours and velocity distributions in the distributor are discussed and compared.

Pyro project, one of complex project, is now under research and development. To manage this kind project successfully, it is essential to apply the processes of technical management (TM) based on systems engineering (SE) and project management (PM). In this paper, the project management processes from ISO-21500 standard, PMBOK guide, and PRINCE2 guide were reviewed, and then some common PM for the large national R&D project were selected. An integrated technical management and project management frame work was finally established and suggested for Pyro project.

In this paper, I described a guide of developing contents to present the direction of developing contents for u-learning. After surveying a character of Ubiquitous computing and u-learning, I described a guide of developing contents which is composed 17 items in 5 fields. This guide is checked by experts and staffs to test a validity and reliability. As a result, It is proven having the validity and reliability. I expect it to guide the direction of developing contents for u-learning. Also, It will contribute to make effective contents which will not affected by technical development and can use continuously because of foreseeing the technical development of future.

Accurate optical texturing of light guide plate over the entire surface area is an important technical issue in LCD TV industry. Injection molding process has the potential to produce large light guide plates having highly efficient optical textures such as micro-prism array. This study is focused on the effect of the degree of replication of the micro texture of the 40" injection molded light guide plates on the overall optical performance of the display panel. Measured replication ratios of the micro-textures formed with three different types of injection molding process were considered in the modeling of prismatic micro segment array. Optical simulation was conducted and results were discussed.

Screw insertion surgery is frequently required among surgical procedures. Especially, very careful attention should be paid to the insertion of screw in the operation of the cervical vertebra. Therefore, there is a need for a guide that allows the surgeon to reliably and promptly perform treatment by calculating the desired insertion angle and length for screw insertion. In this study, the center and direction of the pedicle were calculated through 3D modeling and 3D vector numerical analysis using the CT or MRI image of the patient for the safe operation of the guide, and based on this, After that, we will implement surgical guide based on this.
