Usability is one of the most important concepts regarding software quality. It can be interpreted as the goodness associated with using the software product. This paper distinguishes the goodness of an individual using experience and the goodness of a product for using. This paper proposes a software quality view model which classifies software quality views into two broad categories of end view and means view. End view includes long-term view and short-term view which is classified further into performer's view on software activity and third party's view on software activity. Means view includes intrinsic view and contingency view. The analysis of ISO 25000 Series SQuaRE demonstrates the necessity to decompose product quality model and quality in use model into five models corresponding to the software quality views respectively. The analysis on playability shows that the universal definition of usability may be an illusion. The results provide the theoretical basis to build a comprehensive and consistent body of knowledge regarding software quality, which is consisted with the set of quality models and the theories explaining the relationships among the elements of the models.

This study is to suggest plans that can make service quality and consumer satisfaction high in internet shopping mall , categorizing the determinants of service quality of Internet shopping mall and analysing determinants of service quality which can give much effect on consumer satisfaction. Using the survey method, the study gathered data from 115 consumers and students with purchasing experience on the web. The Cronbach alpha reliability coefficient was computed to assess the reliability of the responses to all instruments and factor analyses were performed to determine construct validity. Multiple regression was employed to test the hypotheses of this study. According to our findings, the determinants of service quality which influences consumer satisfaction are tangibles, responsiveness, problem solving and security. Several implications of the study are provided in the paper.

Many studies reported that some organizations experience benefits of quality as well as the productivity due to the implementation of ISO9000. However, there are significant differences across countries, industries and organizations. This paper examines the current quality management practices in the Hong Kong construction industry under the ISO 9000 environment by a postal survey. It focuses on the success factors of ISO 9000 implementation in the industry. The findings support the views that changes in the organization are needed to realize the benefits brought by ISO 9000.

Purpose: This study aimed to perform a concept analysis of quality nursing care. Methods: Walker and Avant's concept analysis method was used to carry out this study. Results: The defining attributes identified were as follows: caring, the nurse-patient relationship, and patient needs. Antecedents included patient characteristics, individual factors (age, education, knowledge, competence, and experience), job position, and environmental factors. The consequences of quality nursing care have significant influence on both patients and nurses. Conclusion: The findings can aid researchers in obtaining a better understanding of quality nursing care, and stakeholders can consider the factors related to quality nursing care and its consequences to improve the nursing process.

We conducted this study to identify the components of H&B store app service quality and their effect on customer satisfaction. The survey was conducted through an online survey for teenagers or older with experience in using H&B store app. A total of 330 copies were distributed and a total of 282 copies were used for the final analysis. The results of this study are summarized as follows: First, eight factors such as ease of use & design, fulfillment, playfulness, responsiveness, personalization, security, contextual usefulness, interactivity were derived as service quality components of H&B store app. Second, as a result of regression analysis, the six service quality components, such as 'ease of use & design', 'fulfillment', 'playfulness', 'responsiveness', 'security', and 'interactivity' were found to have a significant positive (+) effect on customer satisfaction (p<0.05) and 'playfulness (β=.372)' had the greatest effect on customer satisfaction. Based on the results of this study, we should strive to establish effective marketing strategies in the H&B industry.

High strength concrete(65MPa) was used for construction of the bulk cement storage silo by using sliding form. This paper presents mix design, production, quality control and experience with field application of high strength concrete under cold weather conditions. It is shown to be possible to produce high strength concrete of compressive strength of 50~60 MPa by using high-range water reducer to lower w/c ratio with appropriate quality control.

It is very important to rationally allocate manufacturing processes because customer's needs are being various, and product life cycle in the market Is being shortened. The process allocation is needed before making process control plan and is mostly being done by the field experience or intuition of machine operator, process engineer and/or maintenance technician. Therefore, a modified allocation method using the process variation is proposed. This paper presents the result of comparative studies between current method and the proposed one.

High strength concrete was placed at the mass concrete slabs, walls, pillars of RC building from August till August. And the construction is going on now. This paper presents mix design, production, quality control and experience with field application of high strength ready-mixed concrete under hot weathered conditions. It is shown to be possible to produce high strength concrete that has 45MPa compressive strength using superplasticizer and cement replaced with 20% fly-ash with appropriate control.
