The UML(Unified Modeling Language) Class Diagram which is a part of structure of UML is fit for Object Modeling, and more recently, as the appearance of UXF(UML eXchange Format) UML Class Diagram by itself, can be exchanged in many other different system document. So this paper suggest the conversion system from UML Class Diagram to XML DTD. As this we can easily transformation and saving the UML Class Diagram that is the standard of Modeling Language to XML document which is so reusable. Also it can give a flexible method for the representation to the logical structure of document in various way because of converting XML DTD.

The integrated loader/linker plays a very important role in creating all types of information and ensuring information integrity needed for substantial executions by receiving a PE input file, an intermediate representation of a java class file or a .NET environment, thereby allowing for saving information optimized for verification, resolution, initialization, and execution. This paper proposes a loader/linker system for integrating a java class file and .NET-based PE file. As a means of implementing the loader/linker system, a new execution file format(*.evm) and a memory format were designed to save all information of Java class files and .NET-based PE files, and enable the information in those files to be executed in a JVM or .NET environment through the use of saved execution information.

Class components in a repository require exact information representation by reason of insufficiency of various visual information through search and extraction. In this paper, we have described syntax-analysis method and viewer facilities about class components. In the components analysis, we extracted class information which consists of class_names, methods, attributes, class inheritance relationship, and graphic information. viewer represents extracted class information and creates a new class. Also, it provides facilities of reuse, insertion, and deletion. Not only Viewer represents class hierarchy diagram, and shows detail information about each class, but also it creates new classes. In this paper, we implemented a Viewer using the components, inheritance, diagram information and process. And we enhanced understanding of programs through viewer, and supported prototype for class creation.

The open set recognition method should be used for the cases that the classes of test data are not known completely in the training phase. So it is required to include two processes of classification and the validation test. This kind of research is very necessary for commercialization of face recognition modules, but few domestic researches results about it have been published. In this paper, we propose an open set face recognition method that includes two sequential validation phases. In the first phase, with dummy classes we perform classification based on sparse representation. Here, when the test data is classified into a dummy class, we conclude that the data is invalid. If the data is classified into one of the regular training classes, for second validation test we extract four features and apply them for the proposed decision function. In experiments, we proposed a simulation method for open set recognition and showed that the proposed validation test outperform SCI of the well-known validation method

Fault detection during production processes is one of the required operational tasks to run production processes both safely and consistently. Unexpected operational events or undetected process faults can have a serious impact on the production systems and subsequently on the final products' quality. In addition, such situations may lead to malfunctions or breakdowns of production processes. To reliably detect such abnormalities, a new one-class classification-based detection scheme has recently been developed The proposed method consists of four steps:1) noise filtering, 2) feature selection, 3) nonlinear representation and 4) outlier detection. The performance of the proposed scheme was demonstrated using the multivariate data obtained from a simulation process. The results have shown that the proposed method produced reliable monitoring results and outperforms any existing methods with an average improvement of 25.4%. The use of proper feature selection in the proposed framework yielded better detection performance.

The purpose of this study was to analysis the 6th students' conceptions of the nature phenomenon focused on the systematic characteristics. For this study, 12 students of the 6th grades participated in special class for testing their conceptions about the water cycle in the earth system. And we analyzed the outcomes of students' conceptions based on SBF conceptual representation. The results indicate that most of the subjects perceived that the water cycle in earth system wasn't complex system maintaining its existence and functions as a whole through the interaction of its parts but simple system maintaining some actions between atmosphere and hydrosphere, geosphere, biosphere(biological world). And they didn't perceive the characteristics of the water cycle whose all parts must be presented the change of volume between vapor and water, glacier proposing the total hydro-volume are established in the earth system. Based on the results, it was suggested that the main goals of the schools' science education should be to provide students who understand the water cycle system as attaching importance to form with the skills needed to coherent understanding of the essential qualities for the nature phenomenon system.

Using interesting video clips corresponding to lesson subjects for students who favour visual representation is one of the good methods to enhance students' preference for science class. There are many moving picture web sites to get video clips easily via internet and 'YouTube' is very popular and one of the largest reservoir. In this study, every student in the 'Chemistry I' class, which is a class for 11th grade, was requested to search a video clip corresponding to lesson subjects and to make a presentation in the class. After 1st semester, students' response about the class using YouTube was examined by survey. As a result, students preferred and were interested in the class using YouTube than class centered on textbook. And students preferred YouTube clips showing unusual experiments that were related with contents of subject. In addition, experiments and watching their real phenomena were an interesting factor and helpful factor of learning chemistry in YouTube video clips, respectively. However, translation of English used in the video clips seemed to be a difficult part for students.

In this paper, it will be supplied to the representation of event abstraction which is useful for understanding information relationship of the object-oriented programs. And the clustering concept with the events will be applied to abstract the events. By clustering the events, user can set the information about the function of the classes and the retrieval of the class library.

This study explored the contribution of mother's representation of her mother and father during early years, marital satisfaction, and husband's participation in child caring to mothers' parenting behaviors. The subjects were 253 middle-class mothers and fathers in Seoul who had 2-to 3-year-old children. The data were gathered through questionnaires developed for the current study. As predicted, marital satisfaction and husband support as well as early family experiences were significant variables in predicting positive mothering for mothers of young children. However, the most powerful predictor of mothers' parenting turned out to be marital satisfaction. It was noteworthy that mothers who experienced positive and secure relationships with their own mothers were actively involved/intimate with their children whereas mothers who had insecure relationships with their own fathers showed more authoritarian control over their children.

In this paper we give a simple and direct proof of an Euler integral representation for a special class of _q+1F_q,k k-hypergeometric functions for q ≥ 2. The values of certain ₃F_2,k and ₄F_3,k functions at $x=\frac{1}{k}$, some of which can be derived using other methods. We may conclude that for k = 1 the results are reduced to [3].
