Historical books are records of information using text and images and is one of the valuable cultural heritages of mankind. However, these books wear, tear and are damaged with time, so we are restricted in our usage of them for study or research. There are many libraries and museums around the world researching a method to digitize the historical books to prevent their collection from damage. Digitizing the historical books not only produce digital images but also a valuable high quality digital information. Digitizing process also keeps the original content of the historical books as well as add a value as research material as a bibliographical, artistic and archaeological item. Furthermore, its information would be provided through a network, like internet, to share and to promote more advanced studies. The purpose of this study is to examine the principles and method of digitization of historical books. This study also researches the meaning and problems of digitizing process for more effective usage.

ENC(Electronic Navigational Chart) is an electronic chart that digitize nautical chart including all kinds of information of nautical chart. Mariners have difficulty reading information because of clutter problem if display scale of ECDIS is lower than compilation scale of ENCs. IHO made SCAMIN improvement model included in S-65 Standard to settle this ENC clutter problem. This SCAMIN model includes both simple restriction that should safety some requirement and share geographic information. and hard restriction that should overlap with area object such as depth area, land area, dredge area. It also apply SCAMIN step of sounding value according to importance of safety navigation. In this paper, we analyzed the restrictions for SCAMIN model of S-65 Standard, developed algorithm and application to apply theses restrictions reasonably and mechanically. Also we applied this algorithm and application to Korea ENCs and evaluated the result of performance.

Purpose: The purpose of this study is to develop three-dimensional computerized anthropometry(3DCA) and to compare its reliability and accuracy 3DCA with manual anthropometry(MA) for measurement of lips and nasal deformities in unilateral cleft lips and palate(UCLP) patients. Methods: Samples were consisted of six UCLP patients whose facial plaster models were available immediately before and 3 months after the cleft lip surgery. MA of the facial plaster models was carried out using an electronic caliper. In 3DCA, three-dimensional auto-measuring program was used to digitize landmarks and to measure three-dimensional virtual facial models (3DVFM), which was generated with a laser scanner and 3D virtual modeling program. Intraclass correlation coefficients(ICC) were calculated to evaluate reliability and reproducibility of the variables in both methods, and Wilcoxon's signed rank test was done to investigate the difference in values of the same variables of facial models of each patient between two methods. Results: All ICC values were higher than 0.8, so both methods could be considered reliable. Although most variables showed statistical differences between two methods(p<0.05), differences between mean values were very small and could be considered not significant in clinical situation. Conclusion: In clinical situation, 3DCA can be an objective, reliable and accurate tool for evaluation of lips and nasal deformities in the cleft patients.

It is well known that the ground water level changes rapidly before and after the earthquake, and the variation of ground water level prediction is used to predict the earthquake. In this paper, we predict the ground water level in Miryang City using ANFIS algorithm for earthquake prediction. For this purpose, this paper used precipitation and temperature acquired from National Weather Service and data of underground water level from Rural Groundwater Observation Network of Korea Rural Community Corporation which is installed in Miryang city, Gyeongsangnam-do. We measure the prediction accuracy using RMSE and MAPE calculation methods. As a result of the prediction, the periodic pattern was predicted by natural factors, but the change value of ground water level was changed by other variables such as artificial factors that was not detected. To solve this problem, it is necessary to digitize the ground water level by numerically quantifying artificial variables, and to measure the precipitation and pressure according to the exact location of the observation ball measuring the ground water level.

In marine site surveys, drilling boreholes are restrictively conducted, while geophysical surveys are used with ease. To overcome the limitations of marine site survey, various site survey data should be collected and analysed by adopting complementary pros and cons. In this study, the integration assessment was established to digitize 2D geo-layer based on the overlapping of a few borehole data to seismic refraction tomography and to determine 3D geo-information based on the kriging for the design of offshore-foundation. And the overlapping method was proposed considering spatial variability of the tomography and separation distance from borehole position to determine the 2D geo-layer. Finally, the integration assessment was applied to offshore wind-turbine site in Jeju-do, and its applicability was verified based on the cross-validation.

The problem of common difficulties for the implemented business that imposing the Value Engineering(VE) is crucial. Because of the difference in effect of VE by how an abstract concept as function digitize. Furthermore, to improve achievement of VE,, the advancement of VE is demanded. The most of business conducting the VE is pushing this method with the purpose of cost reduction. As explaining this product, the cost occupies the desktop of F1 and the component of product 54% with the result of analyzing the coefficient of functional requirement. Then the functional cost can be confirmed. Through the result of this study, the fact that the desktop, the bluetooth, the probe occupy the most of products with satisfying the function is able to confirm. An effort for cost reduction in purchasing through adjusting a stable quality demanded for the cost reduction is needed. Also, another effort of proper price reduction by diversification of buyer business is needed also.

Eulsukdo located in the Nakdong Estuary plays important role in ecosystem and coastal wetland. There have been various changes in Eulsukdo up to now. Recently, we expect a great change of the western part of shoreline in Eulsukdo due to the floodgate construction but there is few databases. In this study, shorelines were digitized after we had produced the ortho-images by using aerial photos taken for 30 years(8 times). SCE, NSM and EPR were analysed by DSAS 4.2 program using vector data. In addition, the changes of shoreline were analysed in October 2011 from before Eulsukdo water gate construction to now by adding field surveying with VRS. The amount of years shoreline change is -0.34m/yr in 2009(before water gate construction) and -0.50m/yr in 2011(during the water gate construction), and the change trend shows an accumulation aspect.

The Construction Project Information System(CPIS), an information system constructed as part of the Construction Continuous Acquisition & Life-cycle Support(CALS) of the Ministry of Land, Infrastructure, and Transport(MOLIT), is designed to digitize construction projects across all stages, and enable sharing of information so as to enhance the productivity and efficiency of construction projects and secure their transparent administration. One of MOLIT's internal work systems, CPIS focuses on work-handling and data management. However, now over 10 years old after its construction, it focuses on text and document-based construction project information, but it cannot be interfaced with the visualization-based GIS, which limits the sharing and dissemination of information and the determination of the overall construction project status. To resolve the existing CPIS limitations and problems and to upgrade the system, this study examined domestic and overseas GIS technology trends and relevant information systems, and analyzed the CPIS status and problems. It thus proposed total GIS application measures to upgrade CPIS. Also, it identified detailed CPIS utilization measures and GIS application measures by unit system, and analyzed considerations for GIS application.
