Construction technology has an important impact on construction quality, cost and period of construction project, and is restricted by project quality, construction cost and period. Therefore, it is necessary to continuously improve the construction technology, so as to effectively improve the quality of project, reduce the cost of project and control the construction period. This paper will analyze and discuss the relationship between construction technology and project quality, cost, time limit and current situation in detail, and then put forward the effective coordination of four suggestions, in order to provide reference.展开更多

The supply of power resources has become an inseparable part of people's daily production and life. Power grid construction has brought many conveniences to people's lives and promoted the economic development of our country. However, there are still many problems in the construction process, especially in the quality management, which will not only affect the economic benefits of power enterprises, but also adversely affect the social benefits. Only by continuously improving the quality management of power projects and keeping pace with the times, can power enterprises always achieve good social and economic benefits.展开更多

However, due to the large number of fields involved in the construction process of municipal engineering, construction quality and potential risks are extremely easy to cause, which affects the smooth progress of the construction process. Therefore, the construction unit needs to strengthen the development of risk management, improve the supervision mechanism, and organize personnel to conduct real-time supervision and inspection of the construction process, to ensure the construction progress and quality, and to lay a solid foundation for the healthy and stable construction operation and development of municipal engineering.展开更多

The overview of the effect of quality improvement initiatives in this paper focuses on private healthcare providers in Lagos State, Nigeria. The study assesses the impact of donor-funded quality improvement projects on these private healthcare facilities. It explores the level of participation, perceived support, and tangible effects of the initiatives on healthcare delivery within private healthcare facilities. It also examines how these initiatives influence patient inflow and facility ratings, and bring about additional benefits and improvements, provides insights into the challenges faced by private healthcare providers in implementing quality improvement projects and elicits recommendations for improving the effectiveness of such initiatives. Methods: Qualitative research design was employed for in-depth exploration, utilizing semi-structured interviews. Private healthcare providers in Lagos involved in the SP4FP Quality Improvement Project were purposively sampled for diversity. Face-to-face interviews elicited insights into participation, perceived support, and project effects. Questions covered participation levels, support perception, changes observed, challenges faced, and recommendations. Thematic analysis identified recurring themes from interview transcripts. Adherence to ethical guidelines ensured participant confidentiality and informed consent. Results: Respondents affirmed active involvement in the SP4FP Quality Improvement Project, echoing literature emphasizing private-sector collaboration with the public sector. While acknowledging positive influences on facility ratings, respondents highlighted challenges within the broader Nigerian healthcare landscape affecting patient numbers. Respondents cited tangible improvements, particularly in staff management and patient care processes, validating the positive influence of quality improvement projects. Financial constraints emerged as a significant challenge, aligning with existing literature emphasizing the pragmatic difficulties faced by private healthcare providers. Conclusions: This study illuminates the complex landscape of private healthcare provision in Lagos State, emphasizing the positive impact of donor-funded quality improvement projects. The findings provide nuanced insights, guiding policymakers, healthcare managers, and practitioners toward collaborative, sustainable improvements. As Nigeria progresses, these lessons will be crucial in shaping healthcare policies prioritizing population well-being.展开更多

The action is mainly the mutual influence between human activity and geologic environment. When human activity is uncoordinated with objective laws of the geologic environment, the problems of environmental geology or economic loss would occur.Therefore,the level and the changing orientation of geologic environmental quality are relative to the types of human activity,particularly relative to human intentional-activities of geologic environmental exploitation project. The geologic environment fitting to mining may not fit to urban construction,and fitting to water conservancy and hydroelectric projects may not fit to communication,and so on.Economy evaluation on the profit and loss of geologic environmental quality is exactly to depict the level of the profit and loss of geologic environmental quality about geologic environmental exploitation projects and the展开更多

Just because of the gradual increase of human production and activities, the impact on the surrounding environment has become greater and greater. At the present stage of social development, in daily life, we can easily find that the air quality around is getting worse and worse. In this context, more and more people from all walks of life begin to pay attention to the engineering problems of landscaping. This article first expounds the key points of construction in the process of landscaping and puts forward some specific and feasible reference measures for the existing problems at this stage.展开更多

On the assumption that any image distortion could be modeled as the difference between the directional projection-based maps of reference and distortion images, we propose a new objective quality assessment method based on directional projection for full reference model. Experimental results show that the proposed metrics are well consistent with the subjective quality score.展开更多

文摘The year 2018 marks the 40th anniversary of China’s reforms and opening to the world.As an important part of the overall reform effort,reform of the national family planning program,begun in the 1990s as a pilot project focused on quality of care,has achieved historic and significant results.The pilot project,conducted by the State Family Planning Commission of China in a few select areas,was a response to the 1994 International Conference on Population and Development in Cairo,as well as to a range of social and economic changes in China.To achieve quality of care,the pilot project adopted a client-centered approach to refocus China’s family planning efforts on client needs and rights,informed choice of contraceptives and the provision of better quality services.After nearly 10 years of trials,the successful experiences of the pilot project served as the basis of a family planning program reform rolled out nationwide.This paper uses a logic framework approach to review the main activities,outputs,and impacts of the pilot project.The paper argues that the quality of care project not only developed a model that facilitated reorientation of China’s earlier family planning efforts,but has also provided experiences and lessons that can serve as references for the implementation of“Healthy China 2030”in the future.
