As diverse researches are working about location acquisition, storing method, data modeling and query processing of moving objects, the moving object database systems, which can gain, store and manage location information and query processing, are tuning up. As the mobile device is moving but have constraints, the convenience user interface for spatio-temporal query and viewing query result needs. In this paper, we designed user Interface for spatio-temporal query related moving objects, viewing query result, tracing current and past location of those and monitoring. And we designed system for implementation of these interfaces.

In this paper, we propose an implementation of user interaction effect of web application using jQuery. jQuery is a very popular and extensible JavaScript library. It is strong in controlling DOM(Document Object Model), events and Ajax. But, it is poor at advanced effect of web user UI(User Interface). Implementing advanced effects need to extend jQuery or some skills. So, our proposal is a good way to implement UI effects.

Sketch based query plays an important role in shape matching for 3D shape retrieval system. Some researchers suggest the sketch based query interfaces. It is more effective to capture the needs of users rather than query by example. In this paper, we propose a new 2D sketch based query interface with coarse filters for shape matching. Coarse filtering enables to eliminate unfavorable shapes from shapes in DB. For the purpose of coarse filtering, we use two filters with the topological and geometric patterns. For the validity of our method, we show the experimental results.

In this paper, we propose a novel approach of user interface for querying Digital Video Library. Through the proposed user interface, the users can specify the query more easily and precisely for image and video retrieval, resulting in better retrieval accuracy of the system. The prototype of the proposed system allows specification of character, atmosphere, implement, mapping and event for the query. This prototype not only provides users with the convenience of query specification in various aspects, but also can easily be extended to the retrieval systems of various multimedia data.

The interface design for most present query-base model of OPAC systems does not include the function to implement an iterative feedback process till the user arrives at satisfied search results through the interaction with the system. Also, the interface doesn't provide the help function for a user to select pertinent search terms. To formulate a query at the present OPAC system, a user should learn a set of syntax different from system to system. All of above mentioned things make an end-user feel difficult to utilize an OPAC system effectively. This experimental system is attempted to alleviate a few limitations of the present OPAC system by a n.0, pplying the direct-manipulation technique as well as the feedback principle. First, this system makes it unnecessary for a user to learn some syntax for query formulation by providing option buttons for access points. Second, this system makes it possible for a user to decide whether each displayed record is relevant or not, and for keywords included in the relevant records to be automatically stored in order to be used for later feedback. Third, in this system, the keywords stored in [sayongja yongeu bogyanham] can be deleted if unnecessary or can selected as search terms for a query expansion as well as a query modification. Fourth, in this system, after inputting the original query, the feedback process can be proceed without coming back to the previous search step until a user becomes satisfied with the search results. In conclusion, the searching behaviors of heterogeneous users should be continuously observed, analysed, and studied, the findings of which should be integrated into the design for the interface of the OPAC system.

A feedback echo is a structured restatement of the user's query and informs the user what the system intends to do for the query. This provides backtracking of the user's query so that the user knows how the system has interpreted the query. This study scrutinizes whether the feedback echo, as currently available in the INTELLECT commercial system, can improve the performance of a casual user using a restricted natural language database interface. This study concludes that the particular type of feedback echo available in this commercial system was not effective in terms of overall performance for casual users. It is worth mentioning, however, that the feedback echo was effective for the specific type of error: using wrong conditions for data retrieval.

An XML-based mediator system is the one of the methods to virtually integrate distributed heterogeneous information sources. It considers each information source as the virtual XML database and accesses the information source by XML query language. In this paper, we present a design concept and a development result of the graphic user interface that generates XML views for each biological information sources with flexibility and XML queries on the views. In addison to the easy generation of XML views and queries for the integrated schema, the system supports the form of the workflow, in which the part of the query result against biological information sources is used as input data of an another source.

In this paper, a component was designed for a loom in a window, and then a user interface was implemented to be able to connect database and to process various queries. The implemented system has aggregate query processing functions for the loom components existing in the selected area by the mouse and it also supports high level query processing functions represented with chart and pivot table; we can use it as a decision support system. The proposed system can detect temporal or persistent problems in the looms. Therefore, it can be used to raise the productivity and to reduce the cost in textile companies by coping with the situation properly.

With the explosive growth n the numbers and sizes of imaging technologies, Content-Based Image Retrieval (CBIR) has been attacked the interests of researchers in the fields of digital libraries, image processing, and database systems. In general, in the case of query-by-image, in user has to select an image from database to query, even though it is not his completely desired one. However, since query-by-sketch approach draws a query shape according to the user´s desire it can provide more high-level searching interface to the user compared to the query-b-image. As a result, query-by-sketch has been widely used. In this paper, we propose a Java-based image retrieval system that consists of sketch query and image classification. We use two features such as color histogram and Haar wavelets coefficients to search similar images. Then the Leave-One-Out method is used to classify database images. The categories of classification are photo & painting, city & nature, and sub-classification of nature image. By using the sketch query and image classification, w can offer convenient image retrieval interface to user and we can also reduce the searching time.

We propose a graphical object query language called OGPL (Odysseus Graphical Query Language) for Odysseus object databases. By employing simple graphical notations, OGQL provides a user friendly database interface for object databases. OGQL provides a simple graphical notation for advanced features of the object queries such as path expressions including cycles (cyclic queries). Cyclic queries have not been handled in the previous graphical query languages because of their complexity and ambiguity in devising appropriate graphical notations. GOQL also provides a graphical notation for inheritance hierarchy. Since OGQL has been implemented in Java and JDBC standard interface, users can access the remote databases in a web environment and the system has platform-independent architecture.
