Automation systems improve the productivity of works which relate to product design, facilities management, fault processing and quality evaluation. In these systems, the description language for monitoring and control process is called new control language. These are five flow control languages : IL, ST, FBD, SFC and LD. IL and ST are based on left form. FBD, SFC and LD are based on graphic form. Generally, a software which monitors and controls a system is allowed to use just one flow control language. It is impossible to use more than two languages for simulation in the same system environment. In this paper, we analyzed the characteristics of flow control languages and the process of programming in the legacy system. In addition, for the Integrated processing of languages, we propose Extended ST based on the high-level ST language. Based on this research, we implement a graphical language editor and EST-IL convertor. The graphical language editor makes sequence rules, and converts graphical language into EST. EST-IL convertor has a function to convert EST into IL which is similar to assembly language. As the result of this paper, we present a scheme which integrates all the flow control language processing based on IL.

The importance of service industries is growing as the portion of the service sector increases fast in the recent decades. This research deals with service prototyping and testing in a service laboratory. While products are generally tested through prototyping in new product development processes, services are difficult to test because of the characteristic of service, intangibility. A service laboratory, named s-Scape, is the experiment environment which has been developed to test services in virtual space for the purpose of analysis and improvement of real-world services such as hospitals and automobile show rooms. In this research, we present a service prototyping tool and language to support service test in the service laboratory. We first analyze key elements of service prototypes, and then design the service prototype diagram (SPD) and the service prototype description language (SPDL). SPD, which is a variant of the service blueprint, is a graphical tool to be used to generate SPDL. SPDL is an executable language of describing a service prototype of a real-world service in extensible markup language (XML) to experiment the service environment in virtual space. SPD reflects the control and interface of virtual reality devices, as well as key elements of service modeling. SPD represents a service process in which service providers and customers interact with each other in a service scape.

인터넷의 급속한 확대로 인해 컴퓨터 시스템 또는 네트워크 상에서 보안 문제는 점차 중요한 이슈로 다루어지고 있다. 시스템 또는 네트워크에서 보안 문제를 어떻게 다루느냐는 어떠한 보안정책을 구현하고 있느냐와 밀접하게 연결된다. 이 논문에서는 시스템 또는 네트워크에서 다루어지고 있는 기존 보안정책들을 표현할 수 있는, 그래픽 기반의 새로운 보안정책 언어를 제시한다. 이 언어는 객체 지향 기법에 기반을 두고 있는 그래픽 보안정책 기술 언어이다. 보안정책은 객체 내부 상황 및 객체들 사이 연관성을 표현하여 보안정책이 적용되는 상황을 기술하고 보안정책에서 만족되어야 하는 조건 및 행위 또한 객체 내부와 객체간의 연관성으로 표현된다. 객체지향 보안정책 언어는 그래픽 언어이기 때문에 명확하고 이해하기 용이하다는 장점이 있으며 UML의 클래스 다이어그램과 상태도로 대상 시스템을 표현할 수 있으므로 명시된 보안정책들에 대한 분석을 수행할 수 있다는 장점이 있다.

Field sampling requires statistical description to draw inferences from data. Field data, or linear structures, are commonly analyzed by the graphical presentations, such as streonets and rose diagrams. For this purpose the DROPOL program is developed to analyze the data more efficiently with personal computer. DROPOL program written in FORTRAN 77 plots the structural data in points, poles or great circle on equalarea (Schmidt net) or equal-angle (Wulff net) projection surface. It is also capable to project the data from upper or lower hemisphere of stereonet and to draw pole contour diagrams from the plotted data. The rose diagram, representing the frequency of the strike and dip angle, can also be drawn in general or smooth type using $5^{\circ}$ or $10^{\circ}$ degrees interval.

ADE i,1 a software tool for the design and implementation of multi-agent systems. ADE allows a designer to draw a multi-agent system graphically, specify the necessary properties, and deploy their applications. ADE offers a set of intuitive, easy to use interfaces that enable a designer to completely specify the agents and agent interactions in a multi-agent system. In this environment, JATLite/sup ［1］/ is improved significantly. Furthermore, ADE provides a unique set of features for a multi-agent system design tool. An agent description method based on Design roadmap/sup ［2］/ theory, a hierarchy of agents, and a fully featured Java-based Graphical User Interface are combined in ADE. This distinct combination of features mates ADE stand out among the existing multi-agent system design tools. This paper presents the research related to the application of the ADE, along with descriptions of its design and implementation.

In this paper, we present an object-based modeling and language for an object-oriented spatio-temporal database system. For handling the structure of spatio-temporal objects and the spatio-temporal operators, we propose the two layers of data modeling: a spatio-temporal object model (STOM) and an spatio_temporal internal description model (STIM). We then propose STOQL, a spatio-temporal object-oriented query language. STOQL provides an integrated mechanism for the graphical display of spatial objects and the retrieval of spatio-temporal and aspatial objects.

Biplots are the multivariate analogue of scatter plots. They are useful for giving a graphical description of the data matrix, for detecting patterns and for displaying results found by more formal methods of analysis. Nevertheless, when some values are missing in data matrix, most biplots are not directly applicable. In particular, we are interested in the shape variability of principal component biplot which is the most popular in biplots with missing values. For this, we estimate the missing data using the EM algorithm and mean imputation according to missing rates. Even though we estimate missing values of biplot of incomplete data, we have different shapes of biplots according to the imputation methods and missing rates. Therefore we propose a RMS(root mean square) for measuring and comparing the shape variability between the original biplots and the estimated biplots.

Recently, the plate bending analysis has been interpreted in terms of the tensor's components of curvatures and bending moments by presenting the conceptual perspectives of the Hydrostatic Method of Analysis (HM) and theoretical formulations that combine the continuum mechanics with the graphical statics analysis, the theory of thin orthotropic and isotropic plates, and the elasticity theory. In pursuance of uncovering a genuine formulation of the plate's flexural differential equations, that possess the general-covariance and coordinates-independency. This study had then, tackled various natural and structural problems in both solid and fluid branches of the continuum mechanics in a description of such theoretical and conceptual attainment in uncovering the dimensional independent diffeomorphism covariant partial differential laws.

In order to represent multiple regression data, an alternative graphical method, called as SSR Plot, is proposed by using geometrical description methods. This plot uses the relation that the sum of sqaures for regression (SSR) of two explanatory variables is known as the sum of the SSR of one variable and the increase in the SSR due to the addition of other variable to the model that already contains a variable. This half circle shaped SSR plot contains vectors corresponding explanatory variables. We might conclude that some explanatory variables corresponding to vectors which locate near the horisontal axis do affect the response variable. Also, for the regression model with two explanatory variables, a magnitude of the angle between two vectors can be identified for suppression.

As Graphic Information is a intuitive, simple and definite media to transfer information to human, It is widely used and deserved as a information exchange and store media. But the graphic information is so abstract that a human may misunderstand that's real meaning. So In order to transfer a Exact information to a human, a additional picture and description is needed. So, in this paper, A authoring system is suggested that it can be able to give a additional information at each region in graphic information, and to structurize relations between each region and to give linking information between each region using XML Linking Notation. In this paper, An suggested authoring system is implemented to support a authoring facility which is to display graphical information of CGM(Computer Graphic Metafile) and BMP, and to define structural information by selecting each region of graphics image on screen directly, and to save that structural information and linking information with XML Linking notation, and to support a browsing facility which to find hot spot using a structurized graphic information and then to show a proper graph.
