Challenges brought by applications of advanced technologies in education call for new approaches that can best ensure the provision of quality e-learning experiences. This paper presents an ecological approach as one of such approaches to quality assurance in e-learning that can monitor, assess and improve the effectiveness and the links between the various elements of e-learning. The ecological model for QA in e-learning emphasizes interrelation transactions between elements (e.g. providers, learners, cultures and policies) and systemic integration of those elements, and stresses that all these elements within a QA system play an equal role in maintaining balance of the whole. The model focuses attention both on individual and societal/cultural environmental factors as cornerstones for QA efforts in e-learning. It addresses the importance of QA efforts directed at changing QA transactions from provider-centered to 'all stakeholder-oriented', from one-size-fits-all model to 'globally oriented, locally adaptive model' and from control framework to 'culture creation framework'.

The article proves the relevance of developing conceptual frameworks for managing the quality assurance of logistics activities in the context of socio-economic interaction of their participants. It is established that the fundamental difference of the logistic approach in management from traditional approaches is the allocation of a single management function of previously separated, disparate material flows, as well as economic, technological, information integration of chain links into a single system capable of effective management of these flows. It is substantiated that the functioning of the enterprise as a logistics system can be represented in the form of a triad of logistics components, namely: supply logistics, production logistics, sales logistics. Management of quality assurance processes of logistics activities in the context of socio-economic interaction of their participants is a functional component of the entire logistics system due to the quality of work and interaction of all participants in the implementation of certain activities. The quality of logistics activities will affect the level of economic potential, rationalization and optimization of all logistics flows. It is proved that the management of quality assurance processes of logistics activities in the context of socio-economic interaction of their participants involves the following main areas: the introduction of a quality system of logistics processes; development and implementation of the general strategy of quality improvement at the enterprise; internal integration; controlling. Management of quality assurance processes of logistics activities in the context of socio-economic interaction of its participants requires compliance with the following requirements: systematic and comprehensive management of all flow processes; coordination of criteria and indicators for assessing the effectiveness of the entire logistics system; dissemination of the use and application of information technology; ensuring partnerships and close interaction of all participants in sales networks.

방사선치료는 수술, 항암치료와 함께 암의 3대 치료방법으로 많은 암환자들이 방사선치료를 받게 된다. 방사선은 눈에 보이지 않아 방사선 치료기계에서 나가는 방사선의 질과 양을 확인하기 쉽지 않고 산란되는 특성 때문에 다른 장기에 2차암이 유도할 수 있고 최근 치료기술의 발달로 치료 방사선에 대한 보다 정밀한 검증이 필요하게 되었다. 따라서 방사선 치료기기에 대한 품질관리를 철저히 해야만 한다. 국제원자력기구, 미국의학물리학회 등 해외에서는 보고서들을 제시하여 각 지역적인 차원에서 방사선 치료기기의 품질관리에 대한 권고를 제시한다. 하지만 국내는 외국에 비해 규모가 작아 각 병원에서 국외의 권고 중 일부를 선택적으로 사용한다. 국내 병원을 대상으로만 한 방사선치료의 품질관리 권고가 존재하지 않지만 국외의 권고들이 갱신되고 있으며 향후 국내 품질관리 권고를 제작하기 위해 국내 품질관리의 현황 역시 조사 및 갱신 될 필요성이 있으므로 본 연구에서는 방사선치료기에 대한 품질관리 설문지를 제작하여 국내 품질관리 경향에 대한 조사를 실시하였다. 초본으로 제작된 설문지를 국내 5개 기관의 의학물리학자에게 배포하여 설문지의 부족한 점을 파악하고 보충하여 최종 설문지를 제작한 후 이를 전국 72개 병원의 방사선 종양학과에 배포하여 조사를 실시하였다. 72개 병원 중 37개 병원에서 요청에 응답해주었으며 이들 중 97.3%의 병원이 선형가속기를 보유하고 있으며 40.54%, 18.92%, 24.32%의 병원이 각각 근접치료장치, 토모치료장치, 방사선수술장치를 보유하고 있는 것으로 나타났다. 이 밖에 품질관리 인력 및 장치, 국내의 환자 품질관리 현황, 각 치료기별 품질관리 현황에 대한 설문이 실시되었으며 이 결과는 향후 표준 품질관리 절차서가 제작될 경우 사용되기에 좋은 자료가 될 것이다.

In the current pavement construction practice, the state agencies traditionally determine the quality of the as-constructed pavement mix based on individual mixture material parameters (e.g., air voids, cement or asphalt content, aggregate gradation, etc.) and consider these parameters as key variables to influence payment schedule to the contractors and the present and future quality of the as-constructed mixture. A set of empirically pre-determined pay adjustment schedule for each parameter that was differently developed and being used by the individual agencies is then applied to a given project, in order to judge whether each parameter conforms to the designated specifications and consequently the contractor may either be rewarded or penalized in accordance with the payment schedule. With an improved quality assurance system, the Performance Related Specification, the individual parameters are not utilized as a direct judgment factor; rather, they become independent variables within a performance prediction function which is directly used to predict the performance. The quantified performance based on the prediction model is then applied to evaluate the pavement quality. This paper presents the brief history of the quality assurance in asphalt pavement construction including the Performance Related Specifications, statistical performance models in terms of fatigue and rutting distresses, as an example of the performance prediction models, and envisions the possibilities as to how this Performance Related Specification could be utilized in other infrastructures construction quality assurance.

In this paper, we survey recent trends of International Global Navigation Satellite System (GNSS) organizations such as the International Committee on GNSS (ICG), International Civil Aviation Organization (ICAO), International Maritime Organization (IMO), and International Telecommunication Union (ITU), and investigate their impact on the maritime and aviation sectors. Each international organization promotes international cooperation, improvement of service quality, assurance of security, compliance with international regulations, and technological innovation and development. ICG develops a variety of satellite navigation enhancement systems. ICAO establishes international aviation regulations and standards to enhance aviation safety and security. IMO establishes international shipping conventions and rules to protect and regulate the shipping environment. Lastly, ITU establishes international communication regulations and standards. Investigation of such international organizations plays an important role in increasing the efficiency and reliability of GNSS systems. Each international organization promotes international cooperation, improvement of service quality, assurance of security, compliance with international regulations, and technological innovation and development. In the future, interoperability and compatibility with new satellite navigation systems and other GNSS and satellite navigation enhancement systems must be secured, so and thus investigation of international organizations must be conducted first.

Purpose - With the growth of the duty free shop field and an increase in the executive interest in it, it becomes necessary to examine if PBZ (1988) SERVQUAL could be applied to duty free shop service reflecting on this increased interest and the importance of marketing strategy alternative managing multinational customers. Therefore, the present research focused on the comparison of Korean and Chinese consumers. We examined how service quality would affect relationship quality and customer loyalty. Research design, data, and methodology - Surveys were distributed to 235 Korean and 220 Chinese consumers who have visited a Korean duty free shop. We analyzed frequency analysis, mean difference analysis, and reliability analysis, exploratory factor analysis, confirmatory factor analysis, structural equation model analysis, and multi-group analysis. Results - First, perceived tangibles, responsiveness, empathy, assurance, price benefits, product diversity, and IT convenience of duty free shop service all appeared to be positive effect on customer satisfaction; at the same time, only tangibles, responsiveness, empathy, assurance, and price benefits positively affected customer trust. Secondly, customer satisfaction and trust that are the components of the relationship quality appeared to be positive effect on customer loyalty. Thirdly, customers' satisfaction was found to play a full mediating role effect among all of the service quality factors with customer loyalty; however, customer trust was found to have the mediating effects only with tangibles, empathy, assurance, and price benefits. Fourthly, we found a difference between how service quality influences relationship quality and how service quality influences customer loyalty as a function of different nationality. As a result, it appeared that price benefits and IT convenience affected customer satisfaction more among Koreans than among Chinese. Finally, it appeared that customer satisfaction and trust affected customer loyalty more among Chinese than among Koreans. Conclusions - The results of this study contribute to the theoretical knowledge, but also provide strategic alternatives to enhance differentiation, international competence of enterprises led by duty free shop and service quality improvement and customer loyalty of enterprises are drawn as a foundation for constructing international customer relationship in future global era.
