The types of industrial software are classified into package, embedded and system type. The Package type software means industrial ERP, the embedded software is built in industrial devices and the system type software controls the manufacturing and production system, In this paper, we described about the development of evaluation modules which can implement quality test and evaluation fur industrial embedded software. If you are planning to enhance the objectivity and the validity of evaluation modules, it is necessary to construct the system based on international standard. There are two international standard, ISO/IEC 12119 and ISO/IEC 9126 related to quality evaluation of software. Also ISO/IEC 14598-6 is the standard that defines the construction form of the evaluation modules. Based on these standards, We extracted the quality requirements of industrial embedded software and constructed the evaluation modules that can evaluate the content level of the quality requirements.

Recently, it's increasing to use the applied technology related to the quantitative and qualitative growth of industry area. One of them is software to be used in industry area, and software is the most important part in using the industrial equipments. Therefore, the quality of software in the industrial devices determines the performance of the devices. At this time, it's inspired an evaluation and measurement of software quality to have within industrial equipment, and it's forming the research and development in domestic and foreign. In this paper, we constructed evaluation metrics based on ISO/IEC 12119, the International Standard for the general requirements of software and ISO/IEC 9126-2, the International Standard for the evaluation of software qualify characteristics and sub-characteritics, and for this accomplishment, It has been designed and developed industrial software international standard compatible approval system which approve a quality based on quality test result of industrial software using the ISO/IEC 14598-6 that international standard for organization of evaluation module.

In this paper, the software reliability growth model which incorporates the periodic maintenance after the release is proposed. Using the proposed model, the debugging and periodic maintenance cost subject to the required level of the software reliability are investigated. An optimal software release time is derived for a fixed interval of periodic maintenance. To validate the proposed model, release times obtained in this study are compared with examples. The proposed investigation is expected to be served as one of factors in determining the release time of the software where periodic maintenance is considered.

Cost reduction, time to market, and quality improvement of software product are critical issues to the software companies which try to survive in recent competitive market environments. Software Product Line Engineering (SPLE) is one of the approaches to address these issues. The goal of software product line is to maximize the software reuse and achieve the best productivity with the minimum cost. In software product line, software components are classified into the common and variable modules for composition work. In this paper, we proposed a dynamic composition process based on aspect-oriented programming methodology in which software requirements are classified into the core-concerns and cross-cutting concerns, and then assembled into the final software product. It enables developers to concentrate on the core logics of given problem, not the side-issues of software product such as transactions and logging. We also proposed useful composition patterns based on aspect oriented programming paradigm. Finally, we implemented a prototype of the proposed process using Java and Aspect to show the proposed approach's feasibility. The scenario of the prototype is based on the embedded analysis software of telecommunication devices.

Industrial ventilation is one of crucial engineering measures to protect workers from hazardous airborne contaminants. Designing a ventilation system is not an easy task. To solve this problem, U.S. computer programs and softwares have been developed. In Korea, a software, called as VPMC(Velocity Pressure Method Calculation), was developed by Korean Industrial Safety Corporation. Since VPMC is a DOS-based software, it could not be a user-friendly one. In this study, a Windows-based software was thus developed to overcome the difficulty in using a software for designing the ventilation system. As far as we know, this kind of Windows-based software is the first in the world. But this software should be kept being revised. The future work would include introduction of GUI(Graphic User Interface) and enhancement of editing functions by using Data-Base programs.

In this paper, we deal with an optimal software-release problem of determining the time to stop testing and release the software system to the user. The optimal release time problem is considered from maintenance like the periodic distribution of service packs and the unpredictable distribution of patches after the release. Moreover, the environment of software error-detection during operation differs from the environment during testing. This paper proposes the software reliability growth model which incorporates periodic service packs, unpredictable patches and operational environment. Based on the proposed model, we derive optimal release time to minimize total cost composed of fixing an error, testing and maintenance. Using numerical examples, optimal release time is determined and illustrated.

It is necessary to systematically explore the reform plans of the Software Industrial Promotion Law to systematically a representative high-added value future knowledge-based industry, software industry. The current Software Industrial Promotion Law provides only one provision on software business contract procedures, and the Civil Code, the National Contract law or Subcontract Fairness Law regulate other things, so the features of software industry are not properly reflected. To the contrary, the Information Communication Construction Law or the Construction Basic Law effectively prevent disputes by providing material and detailed provisions. Therefore the current software industry needs to be shifted from promotion to fundamental one. That is, as the software industry takes up a large portion at present, so the law should have basic procedural provisions. Also the National Contract Law governs only the contract procedures of public sector, so there should be business performance procedural provisions to regulate the software business formalities of civil sector. And the National Contract Law controls the sale, construction and service of articles at separate contract procedures, but software business contains construction and service characters simultaneously, so there should be business performance procedures fit for software business. Thus this study presented the legislative need and bill on the performance procedures of software business.
