This paper presents a UML CASE tool for collaboration work between remote place. It configured functions to support collaboration work and it applied framework concept to increase extension and reusability. It also constructed UML CASE tool based on framework. It result in not only reflecting various stakeholder's opinions but it also contributing to integrated and consistent modeling.

This paper presents an implementing of Use Case Description writing tool to support systematically writing and editing Use Case Description. It also supports both 1 column and 2 column formats of use case scenarios and increases convenience for editing scenario steps with automated step numbering function we presented. It results in not only user-friendly and effective description for use case but also contributing to development of integrated use case modeling tool with use case diagram.

Multimedia Authoring Tool is a tool for creating multimedia presentations. With this tool, a user can produce playable multimedia documents. A Multimedia Authoring Tool requires input in the form of a spatial layout and a temporal layout. Users can make many mistakes in creating multimedia presentations and verification is required in the Multimedia Authoring process in order to produce multimedia documents. In this study, two verification phases are proposed: Time Computation and Spatiotemporal Conflict Verification. In the experiment conducted for this study, two kinds of verification were carried out: The use of single-phase verification and the use of double-phase verifications. By using these two types of verification, it became easier to successfully detect errors in the spatial and temporal layouts, and the types of verification have also been successful in increasing the success of error detection.

Smart contract, one of the applications of blockchain, is expected to be used in various industries. However, there is risks of damages caused by attacks on vulnerabilities in smart contract codes. Tool support is essential to detect vulnerabilities, and as new vulnerabilities emerge and smart contract implementation languages increase, the tools must have extensibility for them. We propose a design model for extensible architecture of smart contract vulnerability detection tools that detect vulnerabilities in smart contract source codes. The proposed model is composed of design pattern-based structures that provides extensibility to easily support extension of detecting modules for new vulnerabilities and other implementation languages of smart contract. In the model, detecting modules are composed of independent module, so modifying or adding of module do not affect other modules and the system structure.

Simulation is now using in various area as an effective decision analysis tool in complex environment of today. But, There is a focus to the simulation model development and execution better than result analysis. This article will emphasis to the importance of result analysis apart from model development in simulation, and will use R package for profit optimization simulation. R has a various function in statistic analysis and data manipulation, graphic display. So this research can show the value of R as a tool for simulation.

This paper describes the design and implementation of a XCP (Xeline Control Protocol) network system. XCP is an information oriented protocol which delivers information with high reliability according to the predefined rule. The XCP network system is implemented with partly hardware and partly software based on the power line communication(PLC) environment. A network management tool which interacts with devices is also developed. In order to verify the feasibility of the proposed architecture, the implemented XCP network system is evaluated using a lighting control system.

In this paper, we propose ER_Modeler, which is a logical database design tool based on entity-relationship model. ER_Modeler provides the entity-relationship diagrams to be built graphically on windows and generates the graphs into the appropriate data definition language for creating relational database tables. Furthermore, ER_Modeler provides the import/export functions using XML to guarantee the interoperability with ERwin which is one of the most popular commercial products.

When use FMO by error resilience purpose in existing $TYPE1{\sim}2$ compare. But, in This paper, TYPE $3{\sim}5$[Gradual decoder refresh tool] is used as error resilence tool. Experiment result, it shows that Y PSNR improves that use suitable TYPE's FMO. Images using in an experiment had better use Type $3{\sim}5$. Differ with existing paper, dipersed mode appeared result badly. Because spatial correlation is low, acted adversely in intra predication.

Hyperspectral images have shown a great potential for the applications in resource management, agriculture, mineral exploration and environmental monitoring. However, due to the large volume of data, processing of hyperspectral images faces some difficulties. This paper introduces the development of an image processing tool (HYVIEW) that is particularly designed for handling hyperspectral image data. Current version of HYVIEW is dealing with efficient algorithms for displaying hyperspectral images, selecting bands to create color composites, and atmospheric correction. Three band-selection schemes for producing color composites are available based on three most popular indexes of OIF, SI and CI. HYVIEW can effectively demonstrate the differences in the results of the three schemes. For the atmospheric correction, HYVIEW utilizes a pre-calculated LUT by which the complex process of correcting atmospheric effects can be performed fast and efficiently.

The compiler is the key of the prototyping framework for the new memory system. These compiler-centric prototyping tools have several components, including compiler, linker, assembler, and standard libraries. It takes a lot of cost and man power to develop it all at zero base. Therefore, developer usually use a development framework to develop these prototyping tools efficiently. These development frameworks should be free of licensing issues when considering the commercialization of development results. Thus, developer should investigate the development framework, which is free from licensing issues and that provides all of the development environment to enable actual execution. There are three representative compiler-centric development frameworks: GCC, Clang (LLVM), and MS visual studio. There are some differences depending on the release version among them. And, there are some limitations to the freeware and commercial use. We chose LLVM here to explain the development of prototyping tools. This information will help accelerate the development of prototyping tools and will help reduce system development costs.
