One of the most important issues in global village instances like grid and cloud is resource discovery based on client requirements and system status. Applying appropriate mechanisms for resource management improve utilization of resources and avoids overhead in seleceting best resources for performing applications. In this paper we apply bloom filter for data grid information system. In proposed structure resource registration and inquiring are done based on bloom filter mechanism.This approach increases performance of the grid system. Additionally it increases the performance of performing applications and satisfies client requirement.

This study analyzed the previous studies that the user perceived quality of design factors. As a result, the most representative factors and functional classification is divided into non-functional factors showed that. In the level of human behavior, needs can be distinguished between functional aspects factor and motivator factor. When we access to the level of user's expectation, fundamental factor, performance level, and interest level were represented as the main three levels. Also, this study analyzed the sensitivity quality factors that are important in choosing smart-phone using PQ method of Q methodology. It was possible to find representative types such as sensibility focusing type, use-convenience focusing type and stability focusing type by the analysis. The discriminative sensibility focusing type thinks personality expression and social pride as important and this type prefers differentiation from others. The sensibility quality causes of sensibility focusing type are uniqueness, fun, curiosity, surprise, fashion, attracting others’ view, ostentation and emotional attachment. The use-convenience focusing type prefers convenience cumulated by personal experience. This type thinks the sensibility quality causes such as comfort, freedom, expandability and control of device as important. The stability focusing type prefers familiarity by use experience, attachment by intimacy and harmony with personal image as important. This type thinks the sensibility quality causes such as experience, habits, intimacy, conciseness and fun as important.

The application software operated on mobile device like a smart phone is hard to ensure continuously provision of stable services because of limited resource like a battery. Therefore the requirements on the energy consumption of mobile software become one of critical issues in the software development. To cover the problem that the energy consumption requirement of software was not satisfied when code development is completed, we propose an energy consumption analysis technique using software design model, UML state machine diagram. The design model is transferred to Coloured Petri-Net to estimate the energy consumption. Our technique gives a chance to reduce the energy consumption in the process of software development

As the vehicle technology grows rapidly in these days, the factors of practicable tests are increasing. However, it can be exposed to critical conditions to perform field tests with unverified implementations, since when error occurs while driving, directly leads to an unpredictable accident. For this reason, there are various simulators in the market to ensure the safety and provide various kinds of results, yet they are only targeting high value industries with their remarkable expense, which makes private enterprises challenging to purchase. Therefore, in this paper, autonomous vehicle simulation software based on an open-source project is proposed to provide an extensible platform with public license to perform tests in the virtual world.

Spectrum-based Fault Localization (SBFL) is a well-known debugging technique that locates fault in program code by utilizing execution profiles (spectra) of pass and fail test cases. Hence, the performance of SBFL depends on the test cases executed and the test results. In the most extreme scenarios, the debugging process may have to be conducted with only one fail test case, one pass test case or no pass test case. These scenarios might occur due to extremely high or extremely low failure rates or when software testers decide to stop running more test cases due to time and resource constraints. However, limited test case execution profiles may reduce the accuracy of SBFL metrics. In view of this, we evaluate the performance of SBFL metrics in these extreme scenarios to identify the best performing SBFL metric for each of these scenarios. From the experiment results, we have further discovered the convergence in performance for SBFL metrics under these extreme scenarios.

During software programming, code readability is very important because it affects the understanding of the code context, facilitates communication and collaboration between team members, and it avoids problematic software maintenance. In this study, our research hypothesis was that the coding style affects the code readability. Developers who do not comply with coding conventions and guidelines may be more likely to produce code with a low level of readability. To test this hypothesis, we investigated coding rule violations in the source code files of five open source projects and correlated the observed violations with the scores rated by a readability estimation function. We tested whether significant violations of coding conventions affected the readability of developed codes and identified the violations that were related specifically to low readability quality. We consider that our findings will improve the understanding of programmers so they can take appropriate action to generate better quality code.

For the cadastral management advancement, South Korea has upgraded its system through digitization of cadastral map. Recently, due to the computerization of the cadastral management system, various work systems have been developed and operate in cadastral fields for cadastral book information services, cadastral map information services, and real estate services. Especially brand-new information systems have been developed as part of a cadastral resurvey project. Although the operation of diversified systems has no problem in independent work areas, the inefficiency of operation such as data non-coincidence and compatibility issues between system databases has been incurred in mutual utilization and provision of cadastral information. In order to resolve these issues, this study suggests an integration model design strategy of cadastral information systems.

In this paper, it will be explained about an application which able to analyze the quality of java program code in implementing Java Database Connectivity (JDBC). The analysis will be based on existing best practice in implement JDBC. To analyze JDBC, bugs patterns are needed to be compared with existing best practice. Various methods are available to be used in constructing this kind of application, but in this paper, static analysis non-linear method is used in designing this application. Static analysis means the java program code will be read and analyzed without executing. Non-linear means the java program code will not read sequentially, but it will follow the flow of the program code itself. And this application will be called Bedhigasan, which able to detect bugs pattern in implementing JDBC and it will report those bugs to the web page including with location of the bugs.

According to enforcement of basic acts for electronic document and electronic commerce, certified electronic address system is introduced and as certified electronic document intermediary system is introduced, new market for #-Mail service is emerging. For #-Mail service, #-Mail solutions which enable to use are provided other than institutional portions and the currently provided #-Mail solutions are only provided as the form of Portal. However, many users generally show their user experiences which are familiar with Microsoft Outlook and e-mail solutions provided by Groupware. Study objective is regarded as meaningful where design method through the prototype to materialize #-Mail solution of existing portal form as Microsoft Outlook’s embedded function is to be suggested as one of the ways to improve the conveniences of the users from the viewpoints of the User Experience in this study, and technical methods to improve the practicality and applicability of #-Mail is suggested.
