The United Nations has recommended integrating digital technology into various aspects of life, including public services. The objective is to offer real-time, high-quality digital services, improve the delivery of public services, enhance their effectiveness and efficiency, while achieving objectives such as transparency, interoperability and citizen satisfaction. However, most governments in developing countries are unable to keep up with this trend. As a result, they often create digital public services that fall short of users’ expectations. This study aims to identify the fundamental factors influencing the quality of service in relation to user satisfaction and to explore the relevance of digital technology in implementing this quality within Cameroon public administrations. To achieve this, we used a qualimetric research method, which included non-directive interviews, questionnaires, and structured observations. The results showed that the public services offered in our study environment did not meet users’ expectations. However, the study identified the fundamental aspects to be considered in providing quality public services connected to user satisfaction, as well as the strengths of digitization in achieving this quality.展开更多

Reports show continued patient satisfaction after surgery despite not maintaining clinical improvement as measured by evolution scales. Objectives: The present study sought to explore expectations and level of satisfaction in patients after DBS surgery with a semi-structured questionnaire and subsequent correlation with functional scales, Quality of Life (QoL), and motor and non-motor symptoms. Methods: We performed descriptive statistics to represent demographic data, Wilcoxon rank tests to determine significant differences, and Spearman correlation between the applied scales. Results: We evaluated 20 patients with a history of DBS surgery. 45% were female, with a mean age of 55.7 ± 14.15 years, a mean disease duration of 13.42 ± 8.3 years, and a mean time after surgery of 3.18 ± 1.86 years. Patients reported surgery meeting expectations in 85.5% and continued satisfaction in 92%. These two variables showed a significant correlation. Conclusions: This sample of patients remained satisfied after DBS surgery, although we found no differences in motor and non-motor clinimetric scales. Further studies are needed to confirm the importance of assessing quality of life in patients with DBS.展开更多

Some enterprise systems are however more than mere facilitators, they provide the bedrock without which organizations could not function;we term these mandatory systems “non-volitional”(NVS). With hyper-growth in demand for connectivity, telecommunications are typical of sectors where NVS shape the fiercely competitive landscape. Among them, Billing & Revenue Management Systems (BRMS) are a form of credit, providers deliver a service and subscribers later pay for that service. As such, they are “business critical”, meaning failures may affect an organization’s ability to conduct its core business. Failures also impact user satisfaction, a key measure of information systems success. However, relatively few studies empirically test this notion;fewer still evaluate it at organizational (rather than individual) level, while there is a dearth of literature investigating non-volitional systems and, to the best of our knowledge, none whatsoever consider ways of predicting user satisfaction for BRMS. According to a renowned and widely cited conceptual model, user satisfaction is influenced by information, system, and service quality respectively. To test this theory for telecoms BRMS, we applied structural equation modelling to investigate which of these dimensions has the most effect. The results indicate that information quality, system quality, service quality, and user satisfaction are all valid measures of BRMS success. Hypothesized relationships between the four success dimensions were significantly substantiated. The study also identified five measures of information quality, four measures of system quality, four measures of service quality, and four measures of user satisfaction. Once the proposed model had been successfully validated, we tested the level of significance among user satisfaction and the three quality dimensions. Findings showed that service quality had the strongest influence on user satisfaction, with information quality second. This is quite different from other applications considered in our literature review which mostly have information quality as having the strongest impact (knowledge management systems apart).展开更多

This research project was conducted by collecting relevant data from library users of five universities. Specifically, it aimed to measure database users' level of satisfaction and tried to find factors affecting these graduate students who are using databases regularly at their university libraries. An analysis of the collected data shows that the level of database users' satisfaction could be directly affected by the database service quality, the easiness of accessing the system and user perceived notion of usefulness of those databases that they use often. This study also found that database users' gender could be a significant factor in their perceived notion of easiness of accessing databases, and also in their perceived notion of satisfaction for their successful information retrieval operations. The frequency of accessing databases by these graduate students has an impact on users' perceived notion of easiness of database access. The users' school classifications could make a significant difference in their perceived notion on the extent of usefulness of a particular database.展开更多

One of the most important sectors that plays key role for grasping developed condition is banking sector. Banks like other institutions also look for augmenting their profits and increasing their strength by expansion. The designing of bank must involve selection of those that have sufficient success potential. Hence, from several factors of success, the following three criteria factors have been: selected-customer satisfied, one dimensional, and product fully functional. These factors offers three question multi criteria group extracted from a 16 norms. Also, three criteria factors have been studied over a period of five years and important criteria for evaluating the norms. The Analytical Hierarchy Process (AHP) has been employed to calculate the success potential of each norm. The empirical data comprises the longitudinal survey of the agricultural banking of the Semnan province. The paper, also, finds that product fully functional is placed as the first priority.展开更多

A company that provides the solution should have knowledge of the customer needs in the purpose of sailing strategy or upgrade policy. The needs are also directly connected to the user satisfaction. However, the users have respective points of view in the needs as well as they may not identify the requirements to improve the solution. SERVQUAL can be an appropriate method to define and measure the customer satisfaction for the information technology solutions. As a case study of the customer satisfaction, the modified SERVQUAL items and scoring method are applied to a cyber-infrastructure system named CyberL ab in Korea. The measurement results of user satisfaction for CyberL ab are provided to confirm that our proposed method performs as we intended. From the results, we can score the satisfaction level of users and identify their needs in the various aspects. The total user satisfaction level for CyberL ab is scored by 88.3.展开更多

It explores the distinctive economic and cultural features that affect the retailer's relational satisfaction with its consumer goods manufacturers. The study employs a survey based on a face-to-face administered questionnaire. Two hundred and thirty four responses from a survey with Tunisian retailers as well as international retailers operating in Tunisia were obtained. All constructs are measured using five-point Likert type scales (1 = strongly disagree, 5 = strongly agree). Analyses are conducted using exploratory factor analysis and reliability analysis. The results support the original model with however some differences derived from the Tunisian economic setting as a whole, the characteristics of the Tunisian consumer goods industry as well as the clan characteristic feature of the Tunisian collectivistic culture. Thus, the amount of discounts obtained, does no longer contribute to the retailer's economic satisfaction. Moreover, when it comes to social satisfaction, the respondents get uncomfortable, even to deal with a potential negative interaction with their suppliers. For retail companies involved in internationalization in the Maghreb Region, and especially in Tunisia, it seems that other competitive advantages than prices are to be developed, such as the development of private label or other services that create positive perceived value for the Tunisian customer. From a cultural standpoint, western managers have rather to go away from a formalized channel relationship management, while taking into account the importance of interpersonal influence. The study sheds light on the heterogeneity of the so-called Arab-Muslim world. This is highlighted in the management of channel relationship in Tunisia, that is influenced by: (1) The government's price regulation and control, especially in many food products; (2) The relative weak importance of discounts in gaining retailer's economic satisfaction; (3) The reshaping of the local retailing sector due to the arrival of international retail companies; (4) The clan feature of the Tunisian collectivistic culture that advocates putting priority on interpersonal influence in channel relationship's management.展开更多

Mastectomy stigmas are associated with depression, body image dysmorphia, and decreasing quality of life. BREAST-Q is a PROM (Patient Reported Outcome Measures) that has proven useful in measuring satisfaction with breast reconstruction results from the patient’s point of view. <strong>Objectives:</strong> To measure the satisfaction index and improvement in quality of life after breast reconstruction for breast cancer sequelae in our hospital in the last 5 years.<strong> Materials and Methods:</strong> Descriptive Study that includes patients with Breast cancer diagnosis that underwent mastectomy and breast reconstruction (prosthesis or autologous tissue) in “Hospital Central Sur de Petroleos Mexicanos” (January 2015 to January 2020), whose satisfaction index was measured with BREAST-Q one year after reconstruction. <strong>Results:</strong> 153 patients were included in the analysis. Mean global satisfaction was 74 points. We observed a tendency towards higher psychosocial, sexual and appearance satisfaction in patients who underwent reconstruction with autologous tissue. The mean satisfaction with provided information was 64 points and with the medical team > 90 points. <strong>Conclusion:</strong> Breast reconstruction is associated to a high satisfaction index and quality of life improvement regardless of the technique. BREAST-Q proved to be useful in evaluating patient experience and it helped us identify areas of opportunity to improve our care.展开更多

文摘The aim of the article is to determine the extent to which customer satisfaction's in the e-banking in Semnan area had organizational and customer readiness for developing their services. One of the most important sectors that plays key role for grasping developed condition is banking sector. Banks like other institutions also look for augmenting their profits and increasing their strength by expansion. The designing of bank must involve selection of those that have sufficient success potential. Hence, from several factors of success, the following three criteria factors have been: selected-customer satisfied, one dimensional, and product fully functional. These factors offers three question multi criteria group extracted from a 16 norms. Also, three criteria factors have been studied over a period of five years and important criteria for evaluating the norms. The Analytical Hierarchy Process (AHP) has been employed to calculate the success potential of each norm. The empirical data comprises the longitudinal survey of the agricultural banking of the Semnan province. The paper, also, finds that product fully functional is placed as the first priority.

文摘There are numerous information technology solutions including hardware and software. A company that provides the solution should have knowledge of the customer needs in the purpose of sailing strategy or upgrade policy. The needs are also directly connected to the user satisfaction. However, the users have respective points of view in the needs as well as they may not identify the requirements to improve the solution. SERVQUAL can be an appropriate method to define and measure the customer satisfaction for the information technology solutions. As a case study of the customer satisfaction, the modified SERVQUAL items and scoring method are applied to a cyber-infrastructure system named CyberL ab in Korea. The measurement results of user satisfaction for CyberL ab are provided to confirm that our proposed method performs as we intended. From the results, we can score the satisfaction level of users and identify their needs in the various aspects. The total user satisfaction level for CyberL ab is scored by 88.3.

文摘Under the development of computing and network convergence,considering the computing and network resources of multiple providers as a whole in a computing force network(CFN)has gradually become a new trend.However,since each computing and network resource provider(CNRP)considers only its own interest and competes with other CNRPs,introducing multiple CNRPs will result in a lack of trust and difficulty in unified scheduling.In addition,concurrent users have different requirements,so there is an urgent need to study how to optimally match users and CNRPs on a many-to-many basis,to improve user satisfaction and ensure the utilization of limited resources.In this paper,we adopt a reputation model based on the beta distribution function to measure the credibility of CNRPs and propose a performance-based reputation update model.Then,we formalize the problem into a constrained multi-objective optimization problem and find feasible solutions using a modified fast and elitist non-dominated sorting genetic algorithm(NSGA-II).We conduct extensive simulations to evaluate the proposed algorithm.Simulation results demonstrate that the proposed model and the problem formulation are valid,and the NSGA-II is effective and can find the Pareto set of CFN,which increases user satisfaction and resource utilization.Moreover,a set of solutions provided by the Pareto set give us more choices of the many-to-many matching of users and CNRPs according to the actual situation.
文摘Purpose:The aim of the study was to investigate the actual benefits of the electronic official document online submission and approval system and the satisfaction of hospital staff in a medical center in southern Taiwan,and to find out whether there are any differences between medical institutions and general government personnel.Methods:A cross-sectional study was conducted to investigate satisfactory outcome with questionnaires.The subjects were administrators,healthcare professionals and medical personnel of a medical center in the southern part of Taiwan who had signed electronic documents online.A total of 395 questionnaires were sent out,147 of which were valid,and the rate of collecting data survey was 37%.We analyzed with SPSS version 20.Results:The official document approval system was mainly used by administrative units and contractors,accounting for more than 50%of users.Besides,the frequency of use was at least more than once a week.As for the user’s perception of operating system,most people thought that it is easier to choose the format of official document and to set up the duty agent on leave,but in the part of the signing and approval process setting or modifying,it was considered more difficult,accounting for 38.1%.In terms of perceptual usefulness,the average value was 3.81,which showed that the user agreed that the system has met the needs of daily official documents.When some users of service area encountered problems with their use,the clerical staff were able to provide services immediately and have the professional ability to resolve problems,in order to agree to the majority,accounting for 53.7%.In addition,nearly 60%of users rated the official document system positively,with an average of 3.84 satisfaction,which was higher than the certified value of 3,conforming to the standards for satisfaction with the use of official documents.In addition,the role authorization,perceptual easy-to-use and service area were significant(p<0.05).The perceptual usefulness of Subordinate units was also significant(p=0.016).The frequency of use,perceptual easy-to-use,perceptual usefulness,service area and satisfaction were significantly different(p<0.05).The correlation coefficient between perceptual usefulness and user satisfaction was 0.833,indicating that there was a high correlation.The daily usage frequency of contractors was higher than supervisors.However,supervisors had the highest frequency of use every quarter(p=0.135).There was no significant difference between contractors and supervisors in the frequency of use.Conclusion:It is suggested that education and training on the operation of the electronic official document on-line submission and approval system should be conducted,which can enhance the education and training of supervisors and medical personnel.Continually,invite supervisors and medical personnel to provide advices on the official document system as a reference for future improvements of the system.
文摘The current research aims to find out whether the model of the retailer's relational satisfaction, developed in a western setting is relevant in a different economic and cultural field of investigation: the Tunisian post 2011 revolution's emerging context, and in a different industry: the retail industry. It explores the distinctive economic and cultural features that affect the retailer's relational satisfaction with its consumer goods manufacturers. The study employs a survey based on a face-to-face administered questionnaire. Two hundred and thirty four responses from a survey with Tunisian retailers as well as international retailers operating in Tunisia were obtained. All constructs are measured using five-point Likert type scales (1 = strongly disagree, 5 = strongly agree). Analyses are conducted using exploratory factor analysis and reliability analysis. The results support the original model with however some differences derived from the Tunisian economic setting as a whole, the characteristics of the Tunisian consumer goods industry as well as the clan characteristic feature of the Tunisian collectivistic culture. Thus, the amount of discounts obtained, does no longer contribute to the retailer's economic satisfaction. Moreover, when it comes to social satisfaction, the respondents get uncomfortable, even to deal with a potential negative interaction with their suppliers. For retail companies involved in internationalization in the Maghreb Region, and especially in Tunisia, it seems that other competitive advantages than prices are to be developed, such as the development of private label or other services that create positive perceived value for the Tunisian customer. From a cultural standpoint, western managers have rather to go away from a formalized channel relationship management, while taking into account the importance of interpersonal influence. The study sheds light on the heterogeneity of the so-called Arab-Muslim world. This is highlighted in the management of channel relationship in Tunisia, that is influenced by: (1) The government's price regulation and control, especially in many food products; (2) The relative weak importance of discounts in gaining retailer's economic satisfaction; (3) The reshaping of the local retailing sector due to the arrival of international retail companies; (4) The clan feature of the Tunisian collectivistic culture that advocates putting priority on interpersonal influence in channel relationship's management.
文摘<strong>Introduction: </strong>Cancer is one of the most devastating pathologies to affect the breast. Mastectomy stigmas are associated with depression, body image dysmorphia, and decreasing quality of life. BREAST-Q is a PROM (Patient Reported Outcome Measures) that has proven useful in measuring satisfaction with breast reconstruction results from the patient’s point of view. <strong>Objectives:</strong> To measure the satisfaction index and improvement in quality of life after breast reconstruction for breast cancer sequelae in our hospital in the last 5 years.<strong> Materials and Methods:</strong> Descriptive Study that includes patients with Breast cancer diagnosis that underwent mastectomy and breast reconstruction (prosthesis or autologous tissue) in “Hospital Central Sur de Petroleos Mexicanos” (January 2015 to January 2020), whose satisfaction index was measured with BREAST-Q one year after reconstruction. <strong>Results:</strong> 153 patients were included in the analysis. Mean global satisfaction was 74 points. We observed a tendency towards higher psychosocial, sexual and appearance satisfaction in patients who underwent reconstruction with autologous tissue. The mean satisfaction with provided information was 64 points and with the medical team > 90 points. <strong>Conclusion:</strong> Breast reconstruction is associated to a high satisfaction index and quality of life improvement regardless of the technique. BREAST-Q proved to be useful in evaluating patient experience and it helped us identify areas of opportunity to improve our care.
