For semantic retrieval in semantic web environment, it is an important factor to manage and manipulate distributed resources. Ontology is essential for efficient search in distributed resources, but it is almost impossible to construct an unified ontology for all distributed resources in the web. In this paper, we assumed that most information in the web environment exist in the form of RDBMS, and propose a matching method between domain ontology and the existing RDBMS tables for semantic retrieval. Most previous studies about matching between RDBMS tables and domain ontology have extracted a local ontology from RDBMS tables at first, and conducted the matching between the local ontology and domain ontology. However in the processing of extracting a local ontology, some problems such as losing domain information can be occurred since its correlation with domain ontology has not been considered at all. In this paper, we propose a methods to prevent the loss of domain information through the similarity measure between instances of RDBMS tables and instances of ontology. And using the relational information between RDBMS tables and the relational information between classes in domain ontology, more efficient instance-based matching becomes possible.

This study analyzes the motives of Korean women for choosing breast augmentation in a cultural and relational context; in addition, it investigates their evaluations after surgery. Data was collected through in-depth interviews with 10 Korean women in their 20s and 30s who have received cosmetic breast augmentation. Enlarged and made-up breasts are a form of clothing that symbolizes the socio-economic status of women. In the vertical and individualized Korean society, the desire of women for a fashionable body invigorated the appearance management market. Fashion consumers have passively internalized the ideal body trends as the concept of the ideal body-image, which has been constructed by the social structure, markets, and the media. The analysis was rooted in post-modern feminist perspectives on the female body. The ideal body-image internalization process through the social interactions of participants was the main cultural factor to choose breast surgery. The self-image and conformity/individuality of participant were categorized as relational factors for the motivation to undergo breast surgery. The result showed that after surgery the participants achieved positive feedback from their social relationships. They expressed or hid their socio-economic statuses through their purchased fashion bodies. They also showed higher self-esteem and feelings of satisfaction by pursuing individuality and conformity as a member of society. Moreover, they achieved wider fashion options and greater controls over their public/private/secret clothing choices for certain occasions. Cosmetic breast surgery positively empowered individual women while reinforcing the socially manipulated body ideals that oppress women at the same time. Participants internalized socially constructed values and justified their surgery choices.

Recently, Graph Database (GDB) is being used in wide range of industrial fields. GDB is a database system which adopts graph structure for storing the information. GDB handles the information in the form of a graph which consists of vertices and edges. In contrast to the relational database system which requires pre-defined table schema, GDB doesn't need a pre-defined structure for storing data, allowing a very flexible way of thinking about and using the data. With GDB, we can handle a large volume of heavily interconnected data. A network service provider provides its services based on the heavily interconnected communication network facilities. In many cases, their information is hosted in relational database, where it is not easy to process a query that requires recursive graph traversal operation. In this study, we suggest a way to store an example set of interconnected network facilities in GDB, then show how to graph-query them efficiently.

In systemic grammar an English clause is analysed simultaneously from the point view of its ideational function, interpersonal function and textual function. This study deals with only the ideational function of the three functions, which accounts for the underlying content of a clause. Transitivity is the subsystem of the ideational function. It specifies the different types of process that are recongnized in the language and the structures by which they are expressed. The purpose of the paper is to describe the transitivity of English clause on the basis of systemic approach. For this we analyzed the three subsystems of transitivity which are physical process, mental process and relational process in the form of features. And we described the sets of the features of the three different types of process in English clause in the framework of the system network.

The primary purpose of this study was to investigate the relation between paternal self-esteem, child-rearing behaviors and child's self-esteem. The secondary purpose was to examine whether there were significant relational differences according to child's sex. 272 dyads consisting of fifth and sixth grade children in elementary school and their measured by the Self-Esteem Inventory (for children), the Self-Esteem Scale (for fathers), and the Iowa Parent Behavior Inventory: Father form. Pearson's r., F-test, and Ducan's multiple range test were used for data analysis. Paternal self-esteem was significantly associated with 'parental involvement', 'reasoning guidance', and 'intimacy'. Paternal self-esteem was positively correlated with girl's self-esteem. Child's self-esteem was positively related to 'parental involvement', 'limit setting', 'responsiveness', 'reasoning guidance' and 'intimacy'. In sex differences, only boy's self-esteem wasn't related to paternal 'limit setting'. Boys' self-esteem was strongly related to 'parental involvement', and girls' self-esteem was strongly related to 'reasoning guidance'.

In this paper, a enw model-base three-dimensional (3-D) object recognition mehtod using hopfield network is proposed. To minimize deformation of feature values on 3-D rotation, we select 3-D shape features and 3-D relational features which have rotational invariant characteristics. Then these feature values are normalized to have scale invariant characteristics, also. The input features are matched with model features by optimization process of hopjfield network in the form of two dimensional arrayed neurons. Experimental results on object classification and object matching with the 3-D rotated, scale changed, an dpartial oculued objects show good performance of proposed method.

A database program, named Geoscope, was developed to effectively manage the enormous boreholes log data produced during the geotechnical investigation works in construction and mining Industry This program was designed to give a maximum conveniences to the end users when dealing with the geotechnical data obtained. Most of the values related to geotechnlcal attributes can be selected by a simple click of the mouse in list boxes or small windows provided by the program. Logging chart is automatically created at the same time as the input of the data in the form designated by the user. The made file format and the relational database system adopted in this program, furthermore, can allow the data to be associated with other GIS programs.

In shipbuilding area, data sharing is one of the crucial issues. Recently, for collaborative design, ship structural CAD systems adopt the database as its primary storage. Database is useful to deal with the large amount of design information among the heterogeneous design department and design stage. To make the database-based CAD system object-oriented database(OODB) and object-relational database(ORDB) can be used. It is important to select proper database because the CAD system performance mainly depends on access performance of database. In this research, using prototype CAD system from other research, access performance of OODB and ORDB form CAD system was evaluated. STEP application protocol was used as the database schema and experiment was made in query by property and query by region. The results give some idea of how to choose the database for CAD systems.

Documents in a traditional PDM(Product Data Management) system have been managed in a form of scanned document files or electronic documents developed by specific tools. Though each tool manages documents with its own systematical methods, it has drawbacks in data search, data integration and interchange, etc. For this reason, in this research we propose an efficient document management system for PDM by using the SGML(Standard Generalized Markup Language), one of CALS and ISO standards for document interchanges. Among documents to be managed in PDM, the engineering change notification (ECN) is taken into account. The DTD (Document Type Definition) has been constucted based on the logical analysis of the documents format, In addition, based on the DTD, DB classes have been designed by object-oriented paradigms and a prototype for document input/output and search has been developed using UniSQL ORDBMS (Object-Relational DBMS) and PowerBuilder under the client/server environment.

When machining of a free-form surface with a ball endmill it is very important to select proper cutting conditions considering the geometrical shape of a workpiece to make the production more effective and reduce the machining time. Even though the same cutting conditions and materials are used, the cutting system of different geometry part machining shows the different static/dynamic characteristics. In this study, through various cutting experiments, we can construct the data base of stable cutting conditions for the machining of a Zine Alloy. We can get some relational plots between the optimal feedrates and classified shape features and parameters. On the basis of these results, we can develop the feedrate optimization program OptiCode. The developed program make it possible to reduce the cutting time and increase the machining accuracies.
