The construction industry in Korea has seen significant improvements in quality management techniques, driven by the dramatic development of new technology through Manhattanization and enlargements, but compared with technical development, the level of building quality improvement is still lagging behind. In the meantime, as the interest in construction quality soars due to changes in user consciousness, the level of quality that is being demanded is rising. The government has reinforced quality systems by implementing responsible supervision requirements and granting overseas companies permission to enter the supervision business in Korea, and private sector companies also are attempting quality improvement through quality assurance approaches like the preliminary qualification screening system and ISO 9000 series. But currently, building constructions are done only according to the construction specifications of project owners, whose design, materials and construction methods are already decided, and do not leave any necessity or opportunity for technical developments for the quality improvement of contractors. Therefore, in this study, a work process and system improvement plan for payment regulations is proposed, with which contractors can secure quality voluntarily in the building construction phase.

The revolution of information in information society innovates a lot of business processes. and the renewed processes contribute new paradigms of the 21th century. As one of the revolutions, ISO 9000 becomes a standard for developing efficient quality management systems which provide any-time and any-where environments satisfying customer needs. Thus, it becomes important to research on quality management systems for improving quality in information flowing and service domain. In this paper, we describe the applicable direction and the case study of ISO 9001 : 2000 which establishes quality management systems in the domain and hope to help for the Quality enhancement.

Hydroxypropyl terminated PDMS was synthesized by the hydrosilylation reaction with allyl alcohol in the presence of Karstedt's catalyst. And them, an one-pot reaction with HDI isocyanurate trimer and hydroxyethyl methacrylate was conducted to give a silicone-modified urethane acrylate oligomer (PUA oligomer) having 9000 g/mol, weight average molecular weight. The synthesized PUA oligomer was characterized by using FT-IR and GPC. The UV-curable coatings were prepared by PUA oligomer blending with a reactive monomer (phenylthioethyl acrylate) under the different mole ratios. It was found that the refractive index of cured film increased when the reactive monomer was added but there was no relationship between the refractive index and amount of reactive monomer. Also, their transmittance for cured films was not change as increasing the content of reactive monomer.

In this study, we propose a cryptographic module quality evaluation system referenced by ISO/IEC 9000 quality system with Quality, Quality Factor, Quality Subfactor, Metric. Practical application process encryption algorithm based on the encryption algorithm to encrypt the pros and cons valuation of diagnosis, point selection algorithm, analysis, and quality items(quality factor), eliciting constraints derived, such as the cryptographic module design quality evaluation system is set to step 5. The five steps are examples of field-based diagnostic tool for cryptographic operations, the most essential work to be done in order to derive one will work. 2-Factor encryption module for connection between indicator items(quality factor) to identify and ensure the quality of the item the constraints of the environment are two kinds of cryptographic operations. This study is an encryption module and a practical field application system, it presents the standardized model. We have to meet the rapid changes in information technology. The environment, development and the encryption algorithm applied to model a wide variety of on-site development encryption will be able to expect the efficiency.

In spite of the size and complexity of software becomes large and complicated, the demand of rapid development, cost reduction, good productivity and good quality software is increasing in these days. Many methods were proposed for efficient software development such as various Case tools. Metrics, Process improvement model (CMM, SPICE, ISO9000) and etc. However, most of them we useful to manage the whole projects rather than an individual programming. In this paper, we introduced a system for quality assessment and complexity metrics for Java programs to assess the individual programmer's quality rather than team's quality. This system shows not only the metrics value for quality assessment but also the source code and the soucture of classes simultaneously.

In this study, we have carried out test to examine the ignition characteristics, such as a relation of moisture content and combustibility, and ignition temperature using KRS-RG-9000 tester, of significant part of above trees which are representative species of Young Dong Province of Korea. After rainfall, the percentage of moisture content of living leaves and branches was between 52 and 70%. But it was just between 17 and 33% after 144 hours drying at normal temperature. For dead leaves, it was 10% lower than of first. There was a significant difference on ignition characteristics. The hazard of ignition is highest on dead leaves. The ignition temperature of barks and branches is higher so a retard time is long than of living and dead leaves at normal temperature.

The AS 9100 aerospace standard has become the aerospace quality management system standard agreed to, instead of ISO 9001 and MIL-Q-9858A by international aerospace manufacturing companies. In this paper correlative requirements of each of the standards are compared and analyzed. Then the evolutionary concept and its direction is proposed as a guide to participate in the preparation and establishment of current aerospace quality management systems. This study is applicable to the future as well as present aerospace manufacturing activities throughout the world.

Research issues in software engineering in recent may be object oriented methodology and software quality. Since Halstead has proposed metric-software science in 1977, software quality area has been studied in steady but inactively until 1980s. As international standards such as ISO 9000-3, 9126 were enacted in 1990s early, interest in software quality is increased but many problems such as how to validate metric, measure quality or apply metric are remained. This paper proposes software quality metric methodology which software developer or project manager can use in measuring quality and validating metric during software development. The methodology is classified by several phases: establishment of quality requirement, identification of quality metric, data collection, metric implementation, metric validation. In order to show its applicability, test program, metrics and data are applied to each phase of the methodology. Consideration of this methodology as a methodology for software quality measurement similar to development methodology for software development is needed.

Nowadays, public domain software CALS/EC projects give their attention to the importance of test and evaluation (T＆E). This article proposed a survey on T＆E procedures of the international standards ISO 9000-3, ISO/IEC 9126 and ISO 14598, and of the U.S. Army pamphlet as well as that of MIL-STD-498. And features of testing tools such as their characteristics were reviewed for a reference in selecting appropriate one. Large-scale software projects often encounter with problems during T＆E, when they become close to the end of development cycle. The problems generally act as a bottleneck of a project, leading to slippage of the entire schedule. This article tried a close look at the problems and solution alternatives of the T＆E policy, management, and technical issues, and proposed a T＆E model to support a variety of software development environment.

Since 1997, JAB (The Japan Accreditation Board for Conformity Assessment) had started the activity of accreditation for the laboratory based on U.S. PL101-592: the Fastener Quality Act that was signed by President Bush on 1990. The number of accredit laboratories are 69 in Japan, 21 in Taiwan, 2 in Korea and 189 in U. S. A, as of 09/10/1998. The JAB accreditation encompasses the requirements of the ISO/IEC Guide 25, and the relevant requirements of ISO 9002. The purpose of ISO/IEC Guide 25, also had been harmonized as JIS Z 9325 'General requirements for the competence of calibration and testing laboratories 'mainly facilitates and promotes acceptance of calibration and test results between countries to avoid barriers to trade through as 'one stop testing'. The features and differences between Guide 25 and ISO 9000 will be clarify in this report.
