Over time, the import of seafood has been increased causing a corresponding increase in recall and recall costs of the fishery on the threshold level. In order to reduce recall costs and to ensure the safety of imported seafood, a moveable lab and its supporting software specialized in seafood inspection were designed. A new fishery quarantine support system software, ‘M-LIMS’ is proposed to strengthen an inspection and quarantine process for the imported seafood at the local level. This new software reads data from an external inspection equipment when it is connected to a USB or RS232 cable inspection equipment on a regular basis to save a report sent to the server after its use. Reading was possible by reading records on a central server. Each time users can check own data through a mobile device.

In recent years, there has been a growing concern about enterprise resource planning (ERP) implementation in small and medium-sized enterprises (SMEs). In this study, we investigate the relationship among ERP software qualify, vendor support, user information satisfaction. and performance of ERP implementation. The empirical findings of this paper will allow SMEs to identify the importance of relationships with vendors and software itself for the successful implementation of ERP systems. The results provide a useful basis for the SMEs which have limited information capability to focus their attention on the software quality and vendor support in overcoming difficulties and obstacles facing the ERP implementation.

Increasing use of information system has led to larger amount of developing expenses and demands on software. Until recent days, the model using regression analysis based on statistical algorithm has been used. However, Machine learning is more investigated now. This paper estimates the software cost using SVR(Support Vector Regression). a sort of machine learning technique. Also, it finds the best set of parameters applying immune algorithm. In this paper, software cost estimation is performed by SVR based on immune algorithm while changing populations, memory cells, and number of allele. Finally, this paper analyzes and compares the result with existing other machine learning methods.

For a library to be able provide information services and fulfill its function as a knowledge convergence center capable of responding to various information demands, the development of next-generation information systems based on the latest information and communication technology is needed. The development of mobile information services using portable devices such smart phones and tablet PCs and information systems which incorporate the concepts of cloud computing, SaaS (Software as a Service), annotation and Library2.0 is also required. This paper describes a library information system that utilizes collective intelligence and cloud computing. The information system developed for this study adopts the SaaS-based cloud computing service concept to cope with the shift in the mobile service paradigm in libraries and the explosion of electronic data. The strengths of such a conceptual model include the sharing of resources, support of multi-tenants, and the configuration and support of metadata. The user services are provided in the form of software on-demand. To test the performance of the developed system, the efficiency analysis and TTA certification test were conducted. The results of performance tests, It is encouraging that, at least up to 100MB, the job time is approximately linear and with only a moderate overhead of less than one second. The system also passed the level-3 or higher criteria in the certification test, which includes the SaaS maturity, performance and application program functions.

As network has high speed and wide communication capability, users demand diverse and new software to satisfy their needs. To meet users needs, the softwares for multimedia or groupware or distributed virtual environments can communicate the widely distributed information fast and accurately. Even though the technology for this is under development, it is deficient to support the reliable computer communication. Distributed Object System aims, as the new paradigm of distributed system software development to overcome this problem, to obtain in distributed environment the easiness of development and management, expandability, reusability which object oriented technologies support by solving the complexity of communication processing through the object oriented methods. This paper aims to introduce distributed object system, its technological properties and the current status and trend of technology development related to its standardization. Additionally, with explaining the Replicated Shared Object System(RSOS) which is developed in our country as one of the distributed object systems, its future prospects and technical issues are discussed.

Estimating software development effort remains a complex problem attracting considerable research attention. Improving the estimation techniques available to project managers would facilitate more effective control of time and budgets in software development as well as market. However, estimation is difficult because of its similarity to export judgment approaches and fur its potential as an expert assistant in support of human judgment. Especially, in software development for DCS (Distributed Control System), because of infrastructure software related to target-machines hardware and process characteristics should be considered, estimating software development effort is more complex. This paper suggests software development effort estimation technique using neural network. The methods considered are based on COCOMO and case-based projects. Estimation results applied to case-based project appeared to have value fur software development effort estimation models.

The ability to trace change history and dependency relations of software artifacts which are continuously changed has been recognized as an important factor that support quality management activities such as verification, validation, and testing in software system development process. General software configuration management systems provide tracing information for artifacts only within the configuration management system, and it does not go further to changes that occur within personal workspace. This paper provides a solution that helps tracing down not only changes of configuration items but also change history of artifacts existent in personal workspace through the integration of configuration management system and personal workspace. Furthermore, in cases of artifacts which are included in a configuration item, this paper provides a solution that support tracing dependency relations between the artifacts by identifying their version links. For the integration of configuration management system and personal workspace, a revision of configuration item is connected to the artifact's version of the workspace by the tagging mechanism, and traceability for change history and dependency relations of artifacts can be managed more effectively through integrated change process.

Since nuclear power plants (NPPs) increasingly employ digital I&C systems, reliability evaluation for NPP software has become crucial for NPP probabilistic risk assessment. Several methods for estimating software reliability have been proposed, but there is no available tool support for those methods. To support NPP software manufacturers, we propose a reliability measurement tool for NPP software. We designed our tool to provide reliability estimation depending on available qualitative and quantitative information that users can offer. We applied the proposed tool to an industrial reactor protection system to evaluate the functionality of this tool. This tool can considerably facilitate the reliability assessment of NPP software.

Software-In-the-Loop Simulation(SILS) and Rapid Control Prototyping(RCP) are proposed as an integrated development environment to support the development process from system design to implementation. SILS is an environment used to simulate control systems with temporal behavior. RCP offers seamless phase shift from design to implementation based on automatic code generation. There are several toolsets that support control system design and analysis. A few of these tools generate the control software automatically. However, most of these design toolsets do not cover temporal behavior which appears after implementation. In earlier toolsets, the design and the implementation of a control system are considered as two separate processes which mean the conventional development process is not connected strictly. SILS/RCP environments work under an identical platform and use the same representation for system modeling. An integrated SILS/RCP environment makes it possible to design controllers under conditions similar to real execution during off-line simulation and to realize controllers in the early design phase. SILS/RCP environments integrate the design and implementation phases which reduce the time-to-market and provide greater performance-assured design. The establishment of SILS/RCP and the practical design approaches are presented.
