  • Recently, spatial data integration for geoscientific application has been regarded as an important task of various geoscientific applications of GIS. Although much research has been reported in the literature, quantitative assessment of the spatial interrelationship between input data layers and an integrated layer has not been considered fully and is in the development stage. Regarding this matter, we propose here, methodologies that account for the spatial interrelationship and spatial patterns in the spatial integration task, namely a multi-buffer zone analysis and a statistical analysis based on a contingency table. The main part of our work, the multi-buffer zone analysis, was addressed and applied to reveal the spatial pattern around geological source primitives and statistical analysis was performed to extract information for the assessment of an integrated layer. Mineral potential mapping using multi-source geoscience data sets from Ogdong in Korea was applied to illustrate application of this methodology.

  • In this paper, for integrating of data on car parts we model information of parts that PDM system manages. Ontology of car parts applies existing ontology mapping research to integrate into car ontology. We propose a method for semantic integration of PLM object of MEMPHIS based on the integrated ontology. Through our method, we introduce C# ontology model to apply existing C# applications with ontology. We also classify ontology integration into three through examples and explain them. While semantically integrating PLM objects based on the integrated ontology, we explain the need for change of PLM object type and describe the process of change for PLM object type by examples.

  • To take the re-use of software, we need to study the efficient integration method of source programs. When the source programs are merged, it is required the steps of verification for any non-interference on non-identical parts of them. The traditional techniques of the program integration verify non-interference of source programs through the simple comparison of statements of source programs. We propose the efficient integration method using data flow analysis in the programs. A study comparing test results from the traditional method and the proposed method has found that the proposed method is more efficient than the traditional method.

  • This study compares supply chain integration practices of high performing manufacturing plants in Korea and those in the U.S., Japan, and six European countries. Data were drawn from the High Performance Manufacturing(HPM) Round 3, a joint data-collection effort on manufacturing and supply chain management. Specifically, in the automotive, electronics, and machinery industries, we selected twenty Korean plants with high performance reputation and chose the same number of non-Korean plants(HPM top 20), based upon their competitive manufacturing capability index and customer satisfaction index. The Korean plants do not significantly differ from HPM top 20 plants in that internal value creation activities are coordinated and integrated at the corporate level and between plants. The Korean plants, however, demonstrated more integration with suppliers than with customers, and only the two of them were classified as 'outward facing', which pursues greater integration with both customers and suppliers. Unbalanced and lower integration with customers of the Korean plants was attributed to the lower than expected manufacturing capability and customer satisfaction. Implications for supply chain professionals were discussed.

  • The purpose of this study is to make suggestions for the ongoing process of an integration of the Healthy Families Center and the Center for Multicultural Families. Based on previous studies and interview data from nine service workers at the two institutions, we make the following suggestions. First, a systematic analysis tool should be developed in order to evaluate the effects of the integration initiative with reliability and validity. Second, empirical data should be collected from the users after the integration of the two institutions and be used to promote their satisfaction. Third, a specific preparation should be made to enhance the integration process of the service workers. Fourth, the integration should be considered in the context of the community and networks. Finally, further studies are needed to understand how the integration influence family policy and social policy in larger contexts.

  • KARI precision attitude determination system has been developed for high accurate geo-coding of KOMPSAT-2 image. Sensor data from two star trackers and a IRU are used as measurement and dynamic data. Sensor data from star tracker are composed of QUEST and unit vector filter. Filter algorithms consists of extended Kalman filter, unscented Kalman filter, and least square batch filter. The type of sensor data and filter algorithm can be chosen by user options. Estimated parameters are Euler angle from 12000 frame to optical bench frame, gyro drift rate bias, gyro scale factor, misalignment angle of star tracker coordinate frame with respect to optical bench frame, and misalignment angle of gyro coordinate frame with respect to optical bench frame. In particular, ground control point data can be applied for estimating misalignment angle of star tracker coordinate frame. Through the simulation, KPADS is able to satisfy the KOMPSAT-2 mission requirement in which geo-location accuracy of image is 80 m (CE90) without ground control point.
