Third-party assessment, characterized by independence and specialization, is designed to mitigate these shortcomings. However, the implementation of third-party assessment faces challenges too. This paper intends to improve the third-party assessment system and to realize the legislative purpose of the system. Based on social research, discussions and exchanges with relevant parties, and the existing research results, this paper analyzes the challenges and possible optimization measures for the third-party assessment. The challenges include repulsion from policy-making bodies, insufficient independence of assessment bodies, disparity of assessment quality, and limited application of assessment outcomes. Possible optimization measures include promoting fair competition culture, increasing the acceptance of third-party assessment from policy-making bodies, enhancing the quality of third-party assessment, clarifying the relationship between policy-making bodies and assessment bodies, ensuring the independence of third-party assessments, and promoting the application of assessment results.展开更多

Methods A total of 251 couples were enrolled in this study and female patients were divided into two groups. In group Ⅰ, oocytes were inseminated at 6 h after ovum pick-up. In group Ⅱ, oocyte maturity was rapidly categorized by simple assessment system. Mature oocytes were inseminated at 3-4 h after ovum pick-up when oocyte-corona complexes (OCC) exhibited clear thick ring-like halo (RLH) and expanded cumulus cells (CC) or 5-6 h when OCC exhibited RLH and a few clumped and/or dark CC, respectively. Intermediate oocytes were inseminated at 7-8 h when RLH was not found around the OCC and CC were compacted and clumped and/or dark. Results Normal fertilization rate was higher in group Ⅱ (76.5%) than that in group Ⅰ (58.0%) (P〈0.001). However, abnormal fertilization rate was higher in group Ⅰ(11.3%) than that in group 11 (3.6%) (P〈0.001). The cleavage (82.6% vs 90.0%), chemical pregnancy (4. 8% vs 3.9%), twin pregnancy (6. 7% vs 3.9%) and implantation rate (8.4% vs 10.6%) had no statistically differences between group I and Ⅱ. Rate of clinical and singleton pregnancy was higher in groupⅡ (35.3% and 31.4%) than those in group Ⅰ (24.8% and 18.2%) (P〈0.05). Conclusion This simple assessment system is useful and effective for evaluation and categorization of the oocyte maturity with better reproductive outcomes.展开更多

Methods Between August 2014 and February 2015, a total of 140 patients at Ain Shams University Hospitals in Cairo, Egypt received the Arabic version of the ESAS-r. For each patient, the ESAS-r was completed twice, first by the treating physician (as part of the basic assessment) and a second time by the patient, with a maximum of 2 hours between the two assessments. An additional survey was included to assess patients' acceptance of the survey and their preferences. Results Out of 140 enrolled patients in the study, 11 patients refused to complete the questionnaire, and 10 patients were excluded due to incomplete records in their medical records. Complete data was retrieved for 119 patients who were included for further analyses. The 78 (65%) patients declared that the test was clear and easy to complete. They were able to answer the test without help. Collectively, tiredness and sense of well-being were the most commonly encountered symptoms in ratings obtained by both patients and physicians. Tiredness was the only symptom showing a significant difference between the two rating methods, patient-rated scores being higher (P = 0.032). Cronbach's alpha showed that both tests com- pleted by the physician and the patients were internally consistent: the physician-rated test had a coefficient of 0.877, and the patient-rated test had a coefficient of 0.863. All ESAS scores had good internal consis- tency, with a Cmnbach's alpha coefficient of 0.88. The internal consistency remained high after removal of individual symptom scores, with Cronbach's alpha coefficients ranging from 0.823 to 0.902, indicating that no individual question had undue influence on the total ESAS score. Conclusion The ESAS-r was easily understood by and applicable to patients. There was no significant discrepancy in the rates of symptoms reported by the patients and physicians, apart from tiredness. Based on this, the test could be applied on a larger scale with in-home patients. This test can be cost-effective and can decrease the number of hospital visits among advanced cancer patients in need of supportive treat- ment rather than active cancer therapy.展开更多

This paper concentrates on developing a new methodology for the online assessment web applications that could be used while offline. It is important to retrieve the critical data collected during an examination without a provision of a backup mechanism. There is a need for an assessment system that can adapt to work uninterruptedly and without loss of critical data while there is intermittent intemet discontinuity. This paper describes architecture and implementation of online assessment system with offline capabilities. Online assessment system with offline capabilities will not interrupt examinee's experience while appearing for an assessment test if intemet connection is not available. A development methodology is designed and a compliant framework is implemented to enhance online assessment system with offline capabilities.展开更多

With their integration, the teaching method gets constantly updated, and the teaching resources are greatly enriched, which con-spicuously enhances the teaching effect, and is embraced by students. Teaching assessment is a key link in college English teach-ing. Establishing a scientific and perfect assessment system is also an important means to achieve teaching goals, and thus it is im-perative to establish a scientific and reasonable assessment system based on the SPOC platform for college English blended teach-ing. The present paper argues the assessment system from two aspects:establishing assessment criteria and setting up the content of assessment. It aims to establish a scientific and perfect assessment system to promote students'growth, and improve the quality of teaching as well as personnel training.展开更多

For example in Italy the damage assessment of structures after an earthquake is managed from the Italian Emergency Authority, using printed forms (AeDES) which are filled by experts on site generating a lot of confusion in filling and transferring the forms to the Disaster Management Operative Center. Because of this, the paper explores the viability of using mobile communication technologies (smart phones) and the Web to develop response systems that would aid communities after a major disaster, providing channels for allowing residents and responders ofuploading and distributing information, related to structural damages coordinating the damage field reconnaissance. A mobile application that can be run by residents on smart phones has been developed, to give an initial damage evaluation of the area, which is going to be very useful when resources (e.g. the number of experts is limited). The mobile application has been tested for the first time during 2012 Emilia earthquake to enhance the emergency response, showing the efficiency of the proposed method in statistical terms comparing the proposed procedure with the standard procedure.展开更多

China is rich in coal resources and has a large amount of gas with a wide range of distribution. However, China experienced not only adverse effects on coal mining but also gas disasters in underground engineering construction, such as tunnels and chambers. With the increased number of tunnels passing through coal-bearing strata, the incidence of gas accidents is also rising. Therefore, the significance of preventing and mitigating gas disasters should be emphasized, and an effective risk assessment method for gas disasters should be established. On the basis of research on over 100 gas tunnels in China, a relatively ideal gas disaster risk assessment method and system for tunnels are established through the following measures. Firstly, geo-environmental conditions and gas situations were analyzed during construction. Secondly, qualitative analysis was combined with quantitative analysis. Finally, the influencing factors of gas disasters, including geological conditions, gas,and human factors, were investigated. The gas tunnel risk assessment system includes three levels:(1) the grading assessment of a gas tunnel during the planning stage,(2) the risk assessment of gas tunnel construction during the design and construction stages,(3) the gas tunnel outburst risk assessment during the coal uncovering stage. This system was applied to the dynamic assessment of gas disaster during the construction of the Zipingpu tunnel of Dujiangyan–Wenchuan Highway(in Sichuan, Southwest China). The assessment results were consistent with the actual excavation, which verified the rationality and feasibility of the system. The developed system was believed to be back-up and applied for risk assessment of gas disaster in the underground engineering construction.展开更多

Mature oocytes were inseminated at 3-4 h after ovum pick-up when oocyte-corona complexes (OCC) exhibited clear thick ring-like halo (RLH) and expanded cumulus cells (CC) or 5-6 h when OCC exhibited RLH and a few clumped and/or dark CC, respectively. Intermediate oocytes were inseminated at 7-8 h when RLH was not found around the OCC and CC were compacted and clumped and/or dark. Results Normal fertilization rate was higher in group Ⅱ (76.5%) than that in group Ⅰ (58.0%) (P〈0.001). However, abnormal fertilization rate was higher in group Ⅰ(11.3%) than that in group 11 (3.6%) (P〈0.001).

文摘Objective This study aims to test the acceptance, feasibility, and usefulness of the Arabic version of the revised Edmonton Symptom AssesSment System (ESAS-r) among Egyptian patients with advanced cancer and to compare the rates of symptoms documented by patients and physicians. Methods Between August 2014 and February 2015, a total of 140 patients at Ain Shams University Hospitals in Cairo, Egypt received the Arabic version of the ESAS-r. For each patient, the ESAS-r was completed twice, first by the treating physician (as part of the basic assessment) and a second time by the patient, with a maximum of 2 hours between the two assessments. An additional survey was included to assess patients' acceptance of the survey and their preferences. Results Out of 140 enrolled patients in the study, 11 patients refused to complete the questionnaire, and 10 patients were excluded due to incomplete records in their medical records. Complete data was retrieved for 119 patients who were included for further analyses. The 78 (65%) patients declared that the test was clear and easy to complete. They were able to answer the test without help. Collectively, tiredness and sense of well-being were the most commonly encountered symptoms in ratings obtained by both patients and physicians. Tiredness was the only symptom showing a significant difference between the two rating methods, patient-rated scores being higher (P = 0.032). Cronbach's alpha showed that both tests com- pleted by the physician and the patients were internally consistent: the physician-rated test had a coefficient of 0.877, and the patient-rated test had a coefficient of 0.863. All ESAS scores had good internal consis- tency, with a Cmnbach's alpha coefficient of 0.88. The internal consistency remained high after removal of individual symptom scores, with Cronbach's alpha coefficients ranging from 0.823 to 0.902, indicating that no individual question had undue influence on the total ESAS score. Conclusion The ESAS-r was easily understood by and applicable to patients. There was no significant discrepancy in the rates of symptoms reported by the patients and physicians, apart from tiredness. Based on this, the test could be applied on a larger scale with in-home patients. This test can be cost-effective and can decrease the number of hospital visits among advanced cancer patients in need of supportive treat- ment rather than active cancer therapy.
文摘There has been increasing research in developing offline web applications. This paper concentrates on developing a new methodology for the online assessment web applications that could be used while offline. It is important to retrieve the critical data collected during an examination without a provision of a backup mechanism. There is a need for an assessment system that can adapt to work uninterruptedly and without loss of critical data while there is intermittent intemet discontinuity. This paper describes architecture and implementation of online assessment system with offline capabilities. Online assessment system with offline capabilities will not interrupt examinee's experience while appearing for an assessment test if intemet connection is not available. A development methodology is designed and a compliant framework is implemented to enhance online assessment system with offline capabilities.

文摘Comprehensive English is a professional basic course for English majors,with the most class hours and the highest credits.It can be said to be the most important course in English majors.However,the procedural assessment in the previous comprehensive English assessment system,that is,the usual assessment,was largely determined based on the subjective impression of teachers.However,with the emergence of various English learning apps,students’learning methods and content have changed a lot.With major changes,the previous assessment system has not been able to play its due role.Designing a reasonable comprehensive English assessment system based on mobile APP is the unshirkable responsibility of comprehensive English teachers.Carefully and reasonably designed comprehensive English assessment system can promote students to improve learning efficiency,reduce classroom lecture time,improve teaching effect,and play a vital role in cultivating qualified English professionals.
文摘Due to the rapid development of modern science and technology, college English teaching has been improved according-ly. With their integration, the teaching method gets constantly updated, and the teaching resources are greatly enriched, which con-spicuously enhances the teaching effect, and is embraced by students. Teaching assessment is a key link in college English teach-ing. Establishing a scientific and perfect assessment system is also an important means to achieve teaching goals, and thus it is im-perative to establish a scientific and reasonable assessment system based on the SPOC platform for college English blended teach-ing. The present paper argues the assessment system from two aspects:establishing assessment criteria and setting up the content of assessment. It aims to establish a scientific and perfect assessment system to promote students'growth, and improve the quality of teaching as well as personnel training.

文摘Melasma, a kind of damaging disease, is commonly found in women during reproductive age. It causes great harm to patient's confidence and, has an effect on social contact as well. Melasma has been cured effectively by modern medicine and traditional Chinese medicine so far, in contrast, the treatment analysis system is far from flawless. Our research team is going to cooperate with Beijing University of Aeronautics and Astronautics and develop a computer-vision treatment analysis system for facial dermatosis based on present technology. It's supposed to provide clinical doctors with objective standards for melasma and other facial dermatosis.

文摘One common scenario during disasters such as earthquakes is that the activity of damage field reconnaissance on site is not well-coordinated. For example in Italy the damage assessment of structures after an earthquake is managed from the Italian Emergency Authority, using printed forms (AeDES) which are filled by experts on site generating a lot of confusion in filling and transferring the forms to the Disaster Management Operative Center. Because of this, the paper explores the viability of using mobile communication technologies (smart phones) and the Web to develop response systems that would aid communities after a major disaster, providing channels for allowing residents and responders ofuploading and distributing information, related to structural damages coordinating the damage field reconnaissance. A mobile application that can be run by residents on smart phones has been developed, to give an initial damage evaluation of the area, which is going to be very useful when resources (e.g. the number of experts is limited). The mobile application has been tested for the first time during 2012 Emilia earthquake to enhance the emergency response, showing the efficiency of the proposed method in statistical terms comparing the proposed procedure with the standard procedure.

文摘Gas disasters always restrict the tunnel constructions in mountain area, which becomes a major geological barrier against the development of underground engineering. China is rich in coal resources and has a large amount of gas with a wide range of distribution. However, China experienced not only adverse effects on coal mining but also gas disasters in underground engineering construction, such as tunnels and chambers. With the increased number of tunnels passing through coal-bearing strata, the incidence of gas accidents is also rising. Therefore, the significance of preventing and mitigating gas disasters should be emphasized, and an effective risk assessment method for gas disasters should be established. On the basis of research on over 100 gas tunnels in China, a relatively ideal gas disaster risk assessment method and system for tunnels are established through the following measures. Firstly, geo-environmental conditions and gas situations were analyzed during construction. Secondly, qualitative analysis was combined with quantitative analysis. Finally, the influencing factors of gas disasters, including geological conditions, gas,and human factors, were investigated. The gas tunnel risk assessment system includes three levels:(1) the grading assessment of a gas tunnel during the planning stage,(2) the risk assessment of gas tunnel construction during the design and construction stages,(3) the gas tunnel outburst risk assessment during the coal uncovering stage. This system was applied to the dynamic assessment of gas disaster during the construction of the Zipingpu tunnel of Dujiangyan–Wenchuan Highway(in Sichuan, Southwest China). The assessment results were consistent with the actual excavation, which verified the rationality and feasibility of the system. The developed system was believed to be back-up and applied for risk assessment of gas disaster in the underground engineering construction.

文摘Rock slope hazard assessment is an important part of risk analysis for open pit mines.The main parameters that can lead to rock slope failures are the parameters traditionally used in geomechanical classifications,the slope geometrical parameters and external factors like rainfall and blasting.This paper presents a methodology for a hazard assessment system for open pit mine slopes based on 88 cases collated around the world using principal components analysis,discriminant analysis and confidence ellipses.The historical cases used in this study included copper,gold,iron,diamond,lead and zinc,platinum and claystone mines.The variables used in the assessment methodology are uniaxial compressive strength of intact rock;spacing,persistence,opening,roughness,infilling and orientation of the main discontinuity set;weathering of the rock mass;groundwater;blasting method;and height and inclination of the pit.While principal component analysis was used to quantify the data,the discriminant analysis was used to establish a rule to classify new slopes about its stability condition.To provide a practical hazard assessment system,confidence ellipses were used to propose a hazard graph and generate the HAS-Q.The discriminant rule developed in this research has a high discrimination capacity with an error rate of 11.36%.
