In order to improve user accessibility and interactivity, system scalability, service speed, and a non-standard internet web environment, we developed a Web-based geovisualization system of oceanographic information using HTML5 and dynamic particles. In particular, oceanographic and meteorological data generated from a satellite remote sensing and radar measurement and a 3-dimensioanl numerical model, has the characteristics of a heterogeneous large-capacity multi-dimensional continuous spatial and temporal variability, based on geographic information. Considering those attributes, we applied dynamic particles represent the spatial and temporal variations of vector type oceanographic data. HTML5, WebGL, Canvas, D3, and Leaflet map libraries were also applied to handle various multimedia data, graphics, map services, and location-based service as well as to implement multidimensional spatial and statistical analyses such as a UV chart.

Recently many of earlier GIS services are changing to the form of user-participated dynamic geoweb service like many new impressive web 2.0 services substitute for earlier old-fashioned web 1.0 services. Many relevant technologies are necessary to be developed so as to integrate a number of geospatial data and functions all around into the useful geoweb services. It is also necessary to make the integration easy and to cope with the rapid changes in geoweb environment. In this study, the trend of relevant geoweb technologies were reviewed before, and the development of open geospatial service platform were carried out. As a result, open 2D/3D map service engine, user-participated mashup engine, Open API search engine and so on were im plemented as the core components of that platform. The platform will be able to be used as the common platform among a number of applications in the fields such as public/private GIS integration, u-city projects and GIS/LBS services etc.

The mechanical strengths of buried lamellar tears located near the weld toe in the welded tee joints were evaluated in terms of the loss of load carrying capacity as a function of tear area. In static loading, the load carrying capacity was significantly reduced when tear intercepted over 10% of the cross-sectional area of the welded joints. However, the welded joints containing buried tears still failed at stresses over the yield strength of the base metal in the through-thickness direction in spite of the presence of tears up to 20-25% of the area. Fatigue strength of welded joints containing tears markedly reduced with increasing tear areas. Lehigh lamellar tearing test used in this study to produce speicmens was described in detail. The load carrying cpapacity in static loading was influenced by the reduction of supporting area whereas that in fatigue loading was influenced by the stress-concentration effects of lamellar tears and the reduction of supporting area. In bend tests, the pre-existing lamellar tears always grew up toward the weld toe. However, in fatigue loading, cracks grew up and down simultaneously form both the weld toe and the top of lamellar tears because of stress concentration. In fatigue loading, delaminations and decohesion of inclusion/matrix interface generated in multipass welds provided crack propagation paths and enhanced crack propagation because the tips of delaminations and deconhesios acted as stress raisers.

The purpose of this study is to investigate the factors affecting pre-service childcare teachers' job preparation behaviors according to the model of planned behavior theory which has proven useful in predicting various behaviors of human beings, and to provide job search guidance for pre-service childcare teachers in the educational dimension and social welfare dimension. The study model included the factors proposed in the planned behavioral theories such as attitude toward job preparation behavior, subjective norm, perceived behavior control, behavioral intention, and job preparation behaviors. As a result of analyzing the collected data, it was found that there was a statistically significant effect on job preparation behavior through mediation of subjective preparation norms, perceived behavior control, and attitude in that order with regard to job preparation behaviors, and the perceived behavioral control was found to have a direct and indirect effect on job preparation behaviors. Based on this, the theoretical basis for suggesting ways to promote pre-service childcare teachers' job preparation behaviors by raising subjective norms, perceived behavior control, and attitude levels is suggested.

In recent years, In recent years, research on geo-tagged image contents has defined a view frustum based on filming location and direction data and has studied indexes and various query search techniques for efficient search. The existing view frustum model has a limit of using the static visible distance and provides a simple service that displays the huge image contents on the digital map. We show a method to acquire filming location and attitude data and propose a view frustum model that can change the visible distance using geospatial object data. In addition, we describe the augmented reality service that combines the image matching technique so that it can be mapped in the scene where the image contents are captured.

The purpose of this study was to analyze the relationship creativity and motivation. The subjects were 297 gifted students, selected in the examination for entrance to the Science Education Institute for the Gifted located Jeonbuk. To compare the gifted students' creativity and motivation with the normal students', this study used the standardized test, the Creativity Inventory for Students(by Choi & Lee, 2004) and Multi-Dimensional Learning Strategy Test(by Park, 2006). The major results of this study were as follows; First, The gifted students group was high group in the creativity, and especially the gifted girls were significantly higher than the gifted boys. Second, learning motivation of the gifted students were high or than the normal students and the gifted students were inclined to cope actively to challenge situation rather than avoid. Third, The Creativity showed the positive relationship with learning motivation, the negative relationship with avoid motivation, and moderate relationship with competitive motivation. This result suggested that it is very important to encourage gifted students to the intrinsic motivation rather than extrinsic motivation like competition or achievement in education.

This study examines the causal mechanisms of low fertility and regional differentials in Korea. Utilizing the 2005 census and the 2005 vital statistics, and labor statistics at the regional level, major variables were calculated for administrative units of 234 'Gu's, 'Si's and 'Gun's. Gender equity orientation, labor market insecurity and family formation were hypothesized as key factors of recent decline in Korean fertility. This study first presents four maps of gender equity orientation, labor market insecurity, family formation and fertility. Then ANOVA and path analysis were carried out in an effort to generalize the causal mechanisms. Results of analysis reveal that gender equity orientation has played a central role in the second fertility transition in Korea. In metropolitan regions, however, labor market insecurity is found to have a significant influence on the level of family formation and fertility. Family formation also turns out to be an important intermediate variable of fertility.
