This study identifies the dominant factors in the conceptual cost estimate process of flyover development in the Provincial Government of DKI Jakarta that affect accuracy, based on the relationship model between the conceptual cost estimation process of flyover development in the Provincial Government of DKI Jakarta with the accuracy. Furthermore, this study also develops strategies to improve the accuracy based on the dominant factors. Two parts of the method are used in this study. The first method is to obtain the dominant factors in estimating the conceptual cost of flyover development in the DKI Jakarta Provincial Government, which affects accuracy using the SEM-PLS method, which involved 151 respondents. Second, the method to obtain strategies to improve accuracy based on these dominant factors, using the gap analysis. The result shows that four dominant factors affect accuracy: information quality, project definition, cost information, and project characteristics. Improving strategies are obtained based on those identified dominant factors. The finding of this study suggests that these strategies can be compiled into the guideline of the conceptual cost estimate process, which can be a tool to assist relevant agency personnel in carrying out the stages in the process of conceptual cost estimation of flyover development.

Purpose Cost estimating process is an important element within the project life cycle. Comprehensive information, expanded knowledge, considerable expertise, and continuous improvement are needed to obtain accurate cost estimation. The purpose of this paper is to identify the critical factors that affect accuracy of cost estimation and evaluate the degree to which these factors are important from contractors’ and consultants’ viewpoints. Design/methodology/approach Qualitative and quantitative research approaches were adopted in collecting and analyzing the data, and testing the hypotheses. Based on the literature review, a questionnaire was prepared and then was modified according to the results of face-to-face open-ended interviews conducted with 11 project managers. The final version of the questionnaire was distributed to a random sample of 265 respondents. For analyzing the collected data Kendall’s and Mann-Whitney tests were conducted. Findings The analysis revealed that there is a strong agreement between contractors and consultants in the ranking of the factors related to consultant, contractor, design parameters, and information. A slightly weak agreement between contractors and consultants was noted regarding the factors related to market conditions (external factors) and factors related to project characteristics. Furthermore, the results show that the top ten factors affecting the accuracy of cost estimate are clear and detail drawings and specification, pricing experience of construction projects, perception of estimation importance, equipment (cost/availability/performance), project complexity, clear scope definition, accuracy and reliability of cost information, site constraints (access, storage, services), material availability, financial capabilities of the client, and availability of database of bids on similar project (historical data). Originality/value Offers an original view of the concept of accuracy of cost estimates as it relates to the efficiency of the project relying on both literature review and empirical evidence.

BACKGROUND Telemedicine is a system using telecommunication technologies to diagnose, treat, and monitor patients by healthcare physicians and specialists in many developing countries such as Kuwait. Telemedicine services have proven to be successful in reporting and tracking patient records, delivering, real time monitoring, providing correct medications, and early detection of clinical decline. Covid-19 pandemic period have reinforced telemedicine system’s benefits even more in Kuwait. OBJECTIVE The objective of this study is to investigate factors influencing patients’ continuance intention to use telemedicine after the COVID-19 pandemic in the medical sector of Kuwait. METHODS The updated Delone and Maclean (2003) model was utilized to investigate the aforementioned factors. As such, this research applied quantitative research methods with a sample of 290 participants from patients in Dar Al Shifa Hospital, a private hospital in Kuwait which utilizes telemedical services called ‘Sehaty online’. The corresponding data was analyzed using SmartPLS. RESULTS The findings of this study revealed that the relationship of both telemedicine’s information quality and system quality with patient’s satisfaction are significant with (β = 0.377, t = 5.612, P < 0.001), (β = 0.295, t = 4.397, P < 0.001) respectively. While the relationship of service quality and patient’s satisfaction is not significant with (β = -0.056, t = 0.894, P > 0.05). patient’s satisfaction relationship with patients’ continuance intention to use telemedicine found to be significant with (β = 0.403, t = 8.732, P < 0.001). CONCLUSIONS It has been concluded that information quality and system quality have a positive and significant influence on patient’s satisfaction, whereas service quality has an insignificant influence on patient’s satisfaction. Also, patients’ continuance intention to use telemedicine is found to be significantly impacted by their satisfaction.

<p class="ArticleTitle">In recent years, the increasingly innovative and diverse mobile devices have significantly promoted the mobile device-based shopping. What factors influence this kind of shopping? Will consumers purchase things with mobile devices? These are two topics that need to be explored. Through the literature analysis and the empirical research, this study aims to analyze the quality of information, system, service and mobile devices on the mobile device-based shopping platform. Moreover, it studies the attitude of consumers towards mobile device-based shopping, their willingness to adopt the shopping method and the behavioral relationship model in the actual mobile device-based shopping as well as compares the groups of different frequencies of the Internet use in terms of the relationship model.</p>　　With the convenient sampling, this study made an investigation among some of those who had experienced shopping on such mobile devices as tablets or smart phones. The 765 retrieved valid copies of questionnaire were divided into three groups—“often”, “average” and “seldom” according to the frequency consumers undertook mobile device-based shopping and were then compared. The results showed that there were significant differences among the three groups in four relationship paths, including: 1) the information quality of the mobile device-based shopping platform has more significant positive influence on consumers’ attitude path of mobile device-based shopping in the “average” group than in the other two; 2) the service quality of the mobile device-based shopping platform has more significant positive influence on consumers’ attitude path of mobile device-based shopping in the “seldom” group than in the other two; 3) the preference for mobile device-based shopping has much significant positive influence on the behavior path of mobile device-based shopping in the “often” group. According to the research results, different groups have different behavior models. These results can serve as reference information in the decision-making of those who establish mobile device-based shopping platforms and manufacture mobile devices.
