This paper is planned to use randomized response technique which is an indirect response technique on internet as a way of obtaining much more precise information, not revealing secrets of responsors, considering that respondents are generally reluctant to answer in a survey to get sensitive information targeting employees, customers, etc.

In this study, to measure the moisture of compaction, it is designed to use the 2neutron detectors. To perform the optimal design of their circuit, it is planned high voltage generator and voltage stable circuit and they are very suitable for detection demand. Also, it can be count to data calibration excluded count of ripple.

Big data in the supply chain mainly comes from four aspects. One is the relevant data inevitably generated in the process of product value transfer of enterprises in the supply chain, such as production equipment quality data, planned procurement data, product data, etc; On the other hand, it is derived from the ERP data of various companies in the supply chain; The third is e-commerce data from the customer, and the last is data from external or manually entered data. A third-party data service center analysis and mining the data to predict and control the inventory in the process of supply chain operation. It brings innovation and change of management technology and way of thinking to the whole supply chain in many aspects, and finally achieves the goal of coordinated inventory and zero inventory of the whole supply chain.

In this paper we present a data migration method for developing GIS-based Fisheries Resources Information Systems after considering standardization of existing methods and analyzing characteristics of such systems. First, a strategy for data migration is defined. Second, a iterative process to build a spatial database is planned. Third, the process is executed to make database transformations and basic data are converted into real GIS data. Finally, developers and users cross-check data correctness. As a result of our research, we suggest a data migration method for GIS data and confirm its usefulness by applying it to real projects.

The test transimissionof DGPS correction data has been carried out since early 1996. The data has been sent from marine radiobeacon station at Changgi Gap Ligthouse. It was the first test brosdcast of DGPS correction data based on midium frequency of marine radiobeacon where transmission power and rate are 300W and 100bps respectively. However, there has not been any scientific study on the characteristic of the accuracy of a marine DGPS/radiobeacon. Accordingly. this paper investigates the accuracy of the system, which is currently operating in 310KHz. As a result , planned 8 reference station and coverage verified that the differential positioning accuray using themarine radiobeacon is sufficient to ensure the safetyof marine activities around the coast of Korea(position error of distance 107NM at reference station was about10m(drms)).

Facility Management (FM) is a project phase to maintenance and to increase the qualities of product which is planned on the design phase and ensured on the construction phase. In addition, since the approximate time occupied in operation and maintenance phase is the longest from construction project as total approximate cost is about 85% of whole the project, it could be managed and realized primarily. The information of facility is not created on the specific point of project, but it might be created on the whole process of subject project widely. Thus, as the information could not be lost and it can be delivered into computer aided facility management system, it is necessary to manage the facility information. This paper proposed the necessities and the problems of BIM-based data interoperability on the Korean construction projects.

Analysis of variance (ANOVA) is a method to analyze the data from the experimental designs comparing two or more groups or treatments at the same time, and is the most effective tool of analyzing more complex data sets with different source of variations. This article describes the logic of ANOVA, the application of the method to the analysis of a simple data set, and the methods available for performing planned or post hoc multiple comparisons between the treatments means. In addition, the common misuse of the techniques is also discussed to emphasize that an inappropriate statistical analysis is potentially far more harmful than poorly conducted research. Lastly, an example is given for illustration purposes.

The Aerial photographic mission is working of taking picture at appropriate point at operating aircraft. Specially, because multi-looking camera system for 3D spatial data construction don't use large size CCD camera, do use middle size or small size CCD camera, Exterior parameter can't be calculated because of not enough overlap, if taking picture at inappropriate position. Therefore, we can construct 3D spatial modeling data by taking picture at planned points using GPS Positioning information

Modern war is called as information war. So an Information Systems which operate hitech-weapon is evaluated important by the ARMY. As terrain analysis techniques we an essential element, computer-based terrain analysis techniques for the army are developed. This paper studies the method of tactical terrain analysis data base construction and presents cross-country mobility after analysis officer analysis overlayed terrain data. Also, Terrain information data base construction method is presented through this analysis, which planned a suitable plan of operations in order to mission accomplishment in normal times.

To ensure interoperability among TADILs, we need inter-operational system of tactical data link that allows sharing of specific, planned information among different TADILs. In this paper, we have proposed the design of a conceptual software architecture of inter-operational system. For developing of a conceptual software architecture, we analyze the actual condition of ADSI used in the US military and identify functions and quality-attributes. Based on these factors, we design the conceptual software architecture for inter-operational system of tactical data link using Attribute-Driven Design(ADD) method. ADD is consist of three phases - choose the module to decompose, refine the module, repeat the steps for every module that needs further decomposition. To evaluate of ADD results, we apply the Software Architecture Analysis Method(SAAM) which is consist of making evaluation scenarios, choosing indirect scenarios, evaluation scenarios' interaction, and creating an overall evaluation. Through the evaluation, we verify the conceptual software architecture of inter-operational system.
