E-Report System to Help Monitor Student Academic Progress Using Forward Chaining for Grade Promotion According to Student Development Level

The COVID-19 pandemic that has occurred in the world and Indonesia is one of the affected countries. To limit the rate of transmission of COVID-19, the Ministry of Education issued regulations relating to online schools. With this online school, both parents and teachers need media to be able to monitor students' academic progress as long as online schools are implemented. Therefore, we need a system that can assist teachers and parents in monitoring students' academic progress. In this study, an e-report was designed by incorporating the components of students' academic aspect and students' character aspect. This system is supported by a decision support system using forward chaining to determine the feasibility of a grade increase according to the level of development of the student. The output of this system is student grade reports, advice given to parents and grade promotion decisions based on academic and character aspect.

Logistic Regression Analysis of the Influencing Factors of Cryptogenic Stroke with Positive c-TCD

Objective: To explore the influencing factors and logistic regression characteristics of cryptogenic stroke in patients with positive transcranial doppler bubble test (c-TCD). Methods: A total of 134 cases of cryptogenic stroke that were diagnosed by Tianshui First People’s Hospital from November 2018 to April 2020 were selected according to the TOAST (Trial of ORG 10172 in Acute Stroke Treatment) classification criteria. According to c-TCD results, there were 70 cases of right to left shunt that were included in the positive group and 64 cases without right to left shunt in the negative group. Gender, age, smoking, diabetes, hypertension, and factors affecting the positive rate of foam were analyzed. According to the abnormal embolism scale scores, logistic regression equation was used to analyze the independent influencing factors. Results: The influencing factors of cryptogenic stroke in patients with positive c-TCD were correlated with age, gender, and abnormal embolism scale scores (p < 0.05). For each grade increase in age, the proportion of positive foam test was calculated to be 3.21 times, and the proportion of female to male was calculated to be 2.25 times. For each grade increase in the scores, the proportion of positive foam test was calculated to be 2.55 times. Conclusion: Female, older age, and higher scores in the abnormal embolism scale are the influencing factors for cryptogenic stroke in patients with positive c-TCD.

High incidence of hypertension-mediated organ damage in a series of Chinese patients with 17α-hydroxylase deficiency

Objective To analyze the prevalence of hypertension-mediated organ damage (HMOD) and its relationship with enzyme activity of mutant CYP17A1 and other risk factors in patients with 17α-hydroxylase/17,20-lyase deficiency (17-OHD). Methods A total of 68 patients with 17-OHD were recruited in the Peking Union Medical Hospital from 2003 to 2021.The incidence of hypertension and HMOD was analyzed. CYP17A1 sequencing was performed for all patients and the enzyme activity of CYP17A1 mutant was determined by analyzing the characteristics of mutation itself and the functional data reported previously. A logistic regression model was employed to analyze the factors related to HMOD and the specific damaged organs in patients with 17-OHD. Result(s): Sixty-five patients (95.6%) exhibited hypertension,32 of whom were diagnosed with HMOD in this 17-OHD cohort. c.985_987del TAC ins AA (p. Y329KfsX418) (53.8%) and c.1459_1467del (p. del D487_F489) (11.4%) were the top 2 mutations in this cohort, and no correlation was found between enzyme activity of mutant CYP17A1 and HMOD. Age, hypertension grade, and hypokalemia grade were independent risk factors for HMOD in 17-OHD patients. The risk of HMOD increased by 27% for each additional year of age, 7.7-fold for each one-grade increase in hypertension level, and 1.7-fold for each grade of exacerbation of hypokalemia. Conclusion Patients with 17-OHD experience high incidence of HMOD. There was no correlation between the HMOD occurrence and enzyme activity of mutant CYP17A1.Age, hypertension grade, and hypokalemia grade are independent risks for the occurrence of HMOD.

Associations between school enjoyment at age 6 and later educational achievement: evidence from a UK cohort study

Education is influenced by a broad range of factors but there has been limited research into the role that early school enjoyment plays in pupil’s educational achievement. Here we used data from a UK cohort to answer three research questions. What is the association between early school enjoyment and later academic achievement? To what extent do family background factors underlie this association? Do sex differences in school enjoyment underlie sex differences in achievement? School enjoyment was self-reported in two questionnaires completed at age 6. We used multiple imputation to account for missing covariates in this study, giving an imputed sample size of 12,135. Children’s school enjoyment at age 6 associated with sex and cognitive ability but not family socioeconomic background. For example, girls were twice as likely to report enjoying school than boys (OR: 1.97; 95% CI: 1.56, 2.48). School enjoyment strongly associated with later achievement in age 16 compulsory GCSE exams even after adjustment for socioeconomic background and cognitive ability; pupils who reported enjoying school scored on average 14.4 (95% CI: 6.9, 21.9) more points (equivalent to almost a 3-grade increase across all subjects) and were 29% more likely to obtain 5 + A*-C GCSE’s including Maths and English (OR: 1.29; 95% CI: 0.99, 1.7) than those who did not enjoy school. These results highlight the importance of school enjoyment for educational achievement. As a potentially more modifiable factor than socioeconomic background, cognitive ability or sex, school enjoyment may represent a promising intervention target for improving educational outcomes.

Collision prediction on combined horizontal and vertical alignments of two-lane rural highways.

This study investigates the safety effects of combined horizontal and vertical alignments using accident occurrences on two-lane rural highways in Washington. Eight statistical models were developed to establish the relationships between vehicle accidents and their associated factors for eight combinations of alignments by the Poisson, negative binomial, zero-inflated Poisson, and zero-inflated negative binomial. Three selected models were validated. The findings show that degree of curvature is the most successful predictor for horizontal curves combined with vertical alignments. A minimum ratio of 25 of vertical curve radius to horizontal curve radius is recommended for a curve with radius of smaller than 6000 ft (or 1830 m). Vertical curves have relatively little influence on accident occurrences at horizontal tangents. The grade value and length of a grade increase accident occurrences when a horizontal curve or tangent is on a grade. A smaller curve should be avoided introducing at a steep grade.

Improving the quality of concentrates of Stoilensky GOK JSC with the use of magneticAgravity separation

An innovative high-grade magnetite concentrates production technology has been developed and pilot tested for ferruginous quartzites of the Kursk Magnetic Anomaly. This paper assesses the possibility of using magnetic-gravity separation to obtain high-grade products, suitable for direct metallization, from finely disseminated ferruginous quartzites of the KMA. The results of pilot tests are presented for the current production of high-grade magnetite concentrates from commercial concentrates and for the production of pellets at the Stoilensky GOK, which may be used to draw the following conclusions. Commercial magnetite concentrate may be processed by magnetic-gravity separation. The grade improvement (mass fraction of Fetot) in the pilot tests averaged 1.23 %, while the expected grade increase for industrial MG separation is 1.17 %. Magnetite concentrate for pellet production may also be processed by MG separation. The grade improvement in the pilot tests averaged 1.26 %, while the expected grade increase for industrial MG separation is 1.20 %. Magnetite concentrates are diluted with classes of over 0.045 mm. It is recommended to conduct the tests using classified feed. The processing of MG separation overflows, ground to d80 0.045 mm (the size of stage III industrial grinding), demonstrated the lack of prospects for obtaining any commercial product from this product.

Factors associated with delirium and cognitive decline following hip fracture surgery

Aims Postoperative delirium (POD) and postoperative cognitive decline (POCD) are common surgical complications. In the UK, the Best Practice Tariff incentivizes the screening of delirium in patients with hip fracture. Further, a National Hip Fracture Database (NHFD) performance indicator is the reduction in the incidence of POD. To aid in its recognition, we sought to determine factors associated with POD and POCD in patients with hip fractures. Methods We interrogated the NHFD data on patients presenting with hip fractures to our institution from 2016 to 2018. POD was determined using the 4AT score, as recommended by the NHFD and UK Department of Health. POCD was defined as a decline in Abbreviated Mental Test Score (AMTS) of two or greater. Using logistic regression, we adjusted for covariates to identify factors associated with POD and POCD. Results Of the 1,224 patients presenting in the study period, 1,023 had complete datasets for final analysis. POD was observed in 242 patients (25%). On multivariate analysis only preoperative AMTS and American Society of Anesthesiologists grade (ASA) were independent predictors of POD. Every point increase in AMTS was associated with a fall in the odds of POD by a factor of 0.60 (95% confidence interval (CI) 0.56 to 0.63, p < 0.001). Every grade increase in ASA led to a 1.7-fold increase in the odds of POD (95% CI 1.13 to 2.50, p = 0.009). A preoperative AMTS of less than 8 was strongly predictive of POD with area under the receiver operating characteristic of 0.86 (95% CI 0.84 to 0.89). Only ASA was predictive of POCD—every grade increase in ASA led to a 2.6-fold increase in the odds of POCD (95% CI 1.7 to 4.0, p < 0.001). Conclusion POD and POCD are common in the hip fracture patients. Preoperative AMTS and ASA are strong predictors of POD, and ASA predictive of POCD. This may aid in the earlier identification of those most at risk and suited for the patient consent and decision-making process. Cite this article: Bone Joint J 2020;102-B(12):1675–1681.
