Time-frequency analysis is a successfully used tool for analyzing the local features of seismic data.However,it suffers from several inevitable limitations,such as the restricted time-frequency resolution,the difficulty in selecting parameters,and the low computational efficiency.Inspired by deep learning,we suggest a deep learning-based workflow for seismic time-frequency analysis.The sparse S transform network(SSTNet)is first built to map the relationship between synthetic traces and sparse S transform spectra,which can be easily pre-trained by using synthetic traces and training labels.Next,we introduce knowledge distillation(KD)based transfer learning to re-train SSTNet by using a field data set without training labels,which is named the sparse S transform network with knowledge distillation(KD-SSTNet).In this way,we can effectively calculate the sparse time-frequency spectra of field data and avoid the use of field training labels.To test the availability of the suggested KD-SSTNet,we apply it to field data to estimate seismic attenuation for reservoir characterization and make detailed comparisons with the traditional time-frequency analysis methods. 展开更多

The implementation of strategies to achieve the Sustainable Development Goals(SDGs)is frequently hindered by potential trade-offs between priorities for either environmental protection or human well-being.However,ecosystem services(ES)-based solutions can offer possible co-benefits for SDGs implementation that are often overlooked or underexploited.In this study,we cover this gap and investigate how experts from different countries value the SDGs and relate them with ES.A total of 66 countries participated to the survey,and answers were grouped into three macro-regions:Asia;Europe,North America,and Oceania(ENO);Latin America,Caribbean and Africa(LA).Results show that the most prioritized SDGs in the three macro-regions are usually those related to essential material needs and environmental conditions,such as SDG2(Zero Hunger),SDG1(No Poverty),and SDG6(Clean Water).At a global scale,the number of prioritized synergies between SDGs and ES largely exceeded trade-offs.The highest amount of synergies was observed for SDG1(No Poverty),mainly with SDG2,SDG3(Good Health),SDG5(Gender Equality),and SDG8(Economic Growth).Other major synergies among SDGs include SDG14-15(Life below water-Life on land),SDG5-10(Gender Equity-Reduced Inequality),and SDG1-2(No poverty-Zero Hunger).At a global scale,SDG15,SDG13,SDG14,and SDG6 were closely related to ES like climate regulation,freshwater,food,water purification,biodiversity,and education.SDG11(Sustainable Cities)and SDG3 were also relevant in Asia and in LA,respectively.Overall,this study shows the potential to couple future policies that can implement SDGs’strategies while adopting ES-based solutions in different regions of the world. 展开更多

Background: Preterm labor is one of the most public health problems related to neonates admitted to Neonatal Intensive Care Unit (NICU). Poor knowledge among mothers about the care requirements of a preterm neonate is immediate cause for post-discharge medical problems in premature and neonates readmission to NICU. Hence, this study aims to evaluate mothers’ knowledge of caring for premature infants post-discharge from Neonatal Intensive Care Units in the Gaza strip. Methods: A Quantitative-based cross-sectional designs study was used to survey 120 mothers of preterm neonates at the time of preterm neonates discharge by face-to-face interview at Al-Shifa medical complex and Nasser hospital between February and June 2018. Results: The results showed that only about 58.4% of mothers of premature babies had good knowledge about health care needed for premature infants after discharge from NICU. Furthermore, there was no statistically significant difference between the level of knowledge and mother’s sociodemographic characteristics (P-values > 0.05). Conclusion: Mothers’ knowledge of premature infants care was not at the optimal level, which might put the newborns at risk. Therefore, the study emphasizes the necessity of thoughtful exchange of health information between team members and mothers and establishing pre- and post-discharge plans with mothers to start their healthy transition of preterm neonate to home and to ameliorate family concerns. 展开更多

This paper examines the origin,compilation,and circulation of A Barefoot Doctor’s Manual(Chijiao yisheng shouce赤脚医生手册),exploring the relationship between medical politics and knowledge transmission in China,and its impact on the promotion of Chinese medicine across the world.Barefoot doctors were a special group of rural medical practitioners active in a very special socio-political context.Various editions of barefoot doctor manuals and textbooks were published across China after the first publication of the Manual in 1969.The publication of these manuals and textbooks became an indelible hallmark of the“Cultural Revolution”(1966–1976),when political publications predominated.The Manual was not only a guide for barefoot doctors in their daily study and practice,but also a primary source of medical knowledge for ordinary people.In the middle of the 1970s,the Manual was translated into many languages and published worldwide.This paper argues that the publication of A Barefoot Doctor’s Manual embodied a public-oriented mode of knowledge transmission that emerged and was adopted during a very specific era,and though it was eventually substituted by a mode of training embedded in the formal medical education system,it demonstrated the impact of politics on medicine and health in the context of resource scarcity and low literacy.Changes in China’s geopolitical status,the West’s pursuit of alternative approaches to medicine and health,and the World Health Organization’s(WHO’s)concern over health universality and equity all contributed to the translation and circulation of the Manual,facilitating the dissemination of Chinese medicine worldwide.The paper thus presents empirical and theoretical contributions to research on the relationship between medical politics and knowledge transmission in China. 展开更多

Singular rough sets (S-rough sets) have three classes of forms: one-directional S-rough sets, dual of onedirectional S-rough sets, and two-directional S-rough sets. Dynamic, hereditary, mnemonic, and hiding properties are the basic characteristics of S-rough sets. By using the S-rough sets, the concepts of f-hiding knowledge, F-hiding knowledge, hiding degree, and hiding dependence degree are given. Then, both the hiding theorem and the hiding dependence theorem of hiding knowledge are proposed. Finally, an application of hiding knowledge is discussed. 展开更多

Background: The aim of the study was to evaluate the knowledge, attitude and practices on child adoption among infertile women in Douala (Cameroon). Methods: It was a prospective descriptive study of six months duration at the General Hospital and the Dawn Medical Foundation Clinic. Patients of the gynecologic unit presenting with infertility were included. A questioner was administer to each patient with the following variables: Age, marital status, profession, level of education, past gynecologic history, number of children, type and the duration of infertility. Their knowledge, attitude and practice toward child adoption were investigated. Data collected was analyzed using the statistical software EPI-INFO 6.04 and R. p value < 0.05 was considered to be statistically significant. Results: Among the 300 women included, 269 (89.7%) had already heard about adoption, 62.1% through the media. Seventeen percent knew who to meet in order to adopt a child in Cameroon. Two hundred and thirty patients (76.7%) were in favor of adoption but 48.7% of them didn’t want to adopt a child. One percent of patient had adopted a child. The attitude towards adoption was significantly influenced by the duration of infertility of more than 10 years (p = 0.0014). Among women who have at least one child 9.4% wanted adoption against 21.4% who did not want adoption (p = 0.0305). Among women aged between 25 and 30 years, 28.2% wanted to adopt a child against 79.1% who did not want it (p = 0.000). Eighty five percent of women who had secondary infertility did not want to adopt against 44.7% who wanted it (p = 0.0003). Conclusion: The level of knowledge is high in educated patient. However, many women don’t know the right procedure and the structures in charge of adoption. Their attitude is favorable but the practice of adoption remains low. 展开更多

While the nursing community generally agrees that the Doctorate of Nursing Practice (DNP) degree will strengthen nursing as an academic discipline, there is little known about students’ perceptions of the advanced degree. Nursing students enrolled in an accelerated master’s program in nursing (N = 45) were surveyed to assess their knowledge of the DNP degree while also identifying the perceived effect a DNP might have on their careers, on nursing as a discipline, and on public perceptions of nursing practice. In this study, 51% of participants supported the transition to the DNP as the standard degree for practice nursing while 29% were opposed. The majority of participants (71%) planned to pursue an advanced practice nursing degree/certification with 81% of this group signifying that they would do so even if a DNP is required. The majority of participants agreed that the DNP will improve public perception of advanced practice nursing, but 71% thought the title of “doctor” would confuse patients. While current nursing students are generally informed of the upcoming DNP transition, there is disagreement regarding its implications for their careers and for the extent of public understanding. 展开更多

Background: Rheumatoid arthritis (RA) is a chronic and disabling disease that has a major impact on the lives of patients. Objectives: To test the patients’ knowledge about their disease, its treatment, its complications, and if this affects severity of the disease as measured by the disease activity index (DAS 28). Patients and Methods: A sample of 100 patients with RA who met the Criteria of American College of Rheumatology for RA agreed to participate in this study over the period September 2011-March 2012. Patients’ data were obtained by personal interview. The questionnaire included demographic characteristics and the patients’ knowledge about their disease. The disease activity was measured using standard (DAS28). Results: Thirty three percent of the patients didn’t have an idea about their disease, 20% didn’t know the reason for the investigations, 49% didn’t know the treatment and 40% didn’t know the side effects of their medications. Most patients had a high disease activity index, and there was a poor correlation between patients’ educational level and the disease activity. Conclusions: Neither the educational level nor the frequency of hospital admissions had effects on the knowledge about this disease. As most patients had a high disease activity, a better knowledge may improve disease control and prevent complications. 展开更多

A test items knowledge library system of for adaptive learning is proposed in this paper. The first step is to carry out the quantity and quality analysis of the test items by using the Bloom's revised taxonomy and scale anchoring respectively to produce the characteristics for test items. A smoothing method of arbitrary anchoring revised from scale anchoring is first proposed to make tests more accurate in distinguishing test levels. In addition, raised three dimensional indicators based on the Bloom's revised taxonomy are adopted to validate test contents and therefore it concretely describes the examining function of items. The items obtained have the precise and concrete properties; an item knowledge library is therefore constructed combining teaching materials and items using the technologies of ontology and knowledge management. Finally, a knowledge library system of test items is established to achieve the purpose of adaptive learning for learners. 展开更多

The industrial organisations have a vested interest in quality and its practices in making a quantum leap, thereby requiring proper refocusing and rethinking. This is targeted seriously towards firms acquiring Knowledge Systems (KS) in order to nurture the employees' capabilities. Therefore, to enhance performances and their highly creative direction takes consideration of QE (quality engineering) and KS and disciplines complementary to each other. Additionally, the flow of operations and activities of the KS through the application of quality engineering (QE) principles is according to the view of Japanese engineer Taguchi. This aims to achieve good quality in the product design and processes, and also to anticipate problems that may occur before the shipping of the products. In this study, the use of quality control engineering and Taguchi's function methods in determining these properties and the loss caused by the company will be examined. However, the adopted approach of study scope to the society will aid KS. Also, efforts in this direction motivate the employment of a statistical method by Taguchi which relied on the principle of target-oriented quality, representing the value characterising the product quality. 展开更多
