Since commercial operation of Kori-1 nuclear power plant in 1978, twenty units are under operation and six units are under construction at 2011 present. Nuclear power become a main energy source in our country. However, the plant was constructed by a USA vendor in its beginning period, the Quality Assurance requirements of USA was applied. Even though Quality Assurance requirements were newly established to the Korea Atomic Energy Act, its contents are quite similar to those of USA. And 10 CFR 50 App.B, ASME NQA-1 apply to most of nuclear industries as a quality assurance plan. In this paper, Quality Assurance requirement of domestic nuclear industries has been investigated and applicable method of ISO Quality Assurance application to the nuclear industries is suggested by a comparison ISO 9000 and nuclear quality assurance specification.

Current food sanitation systems for meat and livestock in Australia ar underpinned by HACCP-based quality assurance. HACCP-based quality assurance programs have been implemented by all australian red meat industry sectors, from 'farm-to-fork'. These quality assurance programs are (along with other quality and food safety considerations) the collection of a series of sanitation steps and strategies that aim to ensure that only healthy, clean livestock are presented for slaughter; those healthy, clean animals enter a clean processing plant; contact of carcase surfaces with potential sources of contamination is avoided; carcase surfaces are decontaminated before chilling; and subsequent growth of potential contaminants is avoided. Prospects for food sanitation systems for meat and livestock in Australia lie largely in enhancing current and applying new sanitation strategies and procedures within our HACCP-based quality assurance framework. Prospects include increased focus on actual (Versus perceived) risks; on-farm/feedlot pathogen elimination; increased implementation of existing (or new) decontamination technologies; and an improved cold chain.

For reliability and confidentiality of information security systems, the security engineering methodologies are accepted in many organizations. To improve the effectiveness of security engineering, this paper suggests a security methodology ISEM, which considers both product assurance and production processes, takes advantages in terms of quality and cost. To verify the effectiveness of ISEM, this paper introduces the concepts of quality loss, and compares the development costs and quality losses between ISEM and CC through the development of VPN system.

The purpose of this case study is to examine and compare the basic characteristics of quality assurance systems of the 3 leading countries in international higher education: Australia, Canada, and the Netherlands. The comparative analysis of the three cases demonstrates that, taking a more commercial stance on the international education service market, quality assurance systems of the 3 countries aim at facilitating effective promotion of student recruitment and enhancing their national brand image as advanced knowledge society. Consequently, rules and regulations of their systems are concerned primarily with strengthening institutional capacities to educate international students effectively, and, ultimately, improving their learning experiences in the host countries. Compared to these foreign cases, the newly-adopted quality assurance system in Korea places too much emphasis on internationalization process itself, thereby neglecting evaluation of educational capabilities of higher education institutions. Further implications for improvement of the Korean International Education Quality Assurance System(IEQAS) are discussed.

Nowadays most companies are required to acquire the quality assurance system for their survival. It is essential to improvement company's competitive power that Certification of Quality Assurance System but there are many problems. To analysis the effects of ISO 9000 series/QS-9000 QA systems to the Domestic Company Quality Improvement as well as quality consciousness, data has been surveyed form quality assurance engineers who have work on certification activities. The data is analyzed using relevant tabulations of five scale or paired t test method in order to compare level of quality management of pre-certification with that of post-certification. It is analyzed in two parts which are qualitative effects and quality maturity grid. Also, to analysis for the bottlenecks and problems the data is analyzed using frequency analysis method.

Female customers form a major customer group for Internet shopping and their trust on Internet stores seems to be significantly related with their transactions. This paper focuses on female customers' trust on Internet stores, hypothesizing that online service quality has a positive impact on trust and that trust, in turn, together with service quality has a positive effect on loyalty. We investigate trust from three dimensions(benevolence, integrity, and ability) and at the same time, unlike existing research, treat service quality to have five dimensions (intangibles, reliability, responsiveness, assurance, and empathy) as known in SERVQUAL(Parasuraman et al., 1988). Survey data is obtained from the female college student sample. Our research model is justified in terms of construct validity, internal consistency, and goodness of fit. Research hypotheses are tested using SEM(Structural Equation Modeling). The results are as follows: First, assurance and empathy dimensions of service quality have significant impacts on benevolence/integrity dimension of trust. Second, out of the five service quality dimensions, only assurance has a positive effect on ability dimension of trust. Third, assurance dimension of service quality and ability dimension of trust are positively related with customer loyalty. The most important factors for female customers' loyalty are found to be assurance(service quality) and ability(trust). The significance of assurance is in line with findings from existing research. But its relationship with the trust dimensions is uncovered in this research, and the only dimension that impacts on ability is assurance. We find that female customers build trust about internet stores based on their ability rather than on their benevolence/integrity and that the female customers' perception on the internet stores' ability can be improved by higher service quality from the aspect of assurance. Importantly enough, these findings offer practical guidelines to Internet stores to boost female customers' loyalty.

In many of the industrialized countries an increasing amount of infrastructure is ageing. This has become specifically critical to bridges which are a major asset with respect to keeping an economy alive. Life of this infrastructure is scattering but often little quantifiable information is known with respect to its damage condition. This article describes how a damage tolerance approach used in aviation today may even be applied to civil infrastructure in the sense that operational life can be applied in the context of modern life cycle management. This can be applied for steel structures as a complete process where much of the damage accumulation behavior is known and may even be adopted to concrete structures in principle, where much of the missing knowledge in damage accumulation has to be substituted by enhanced inspection. This enhanced and continuous inspection can be achieved through robotic systems in a first approach as well as built in sensors in the sense of structural health monitoring (SHM).
