The Construction of Conceptual Framework of Enterprise Internal Control Evaluation Report

In practice, although there is no doubt about the role of enterprise internal control, how to evaluate the effect of enterprise internal control and the auditability of internal control has always been a difficult problem that plagues the theoretical and practical circles.The problems existing in the construction and development of enterprise internal control, such as the information content problem in the enterprise internal control evaluation report, are largely due to the lack of the conceptual framework of enterprise internal control to guide the internal control theory of enterprises.Therefore, the establishment of a set of conceptual framework for the evaluation report of internal control of enterprises and a full understanding of its importance play an important role in solving the practical problems faced in the practice of internal control of enterprises and promoting the construction and development of internal control of enterprises.The construction of the conceptual framework of the internal control evaluation report of an enterprise should adopt the viewpoint of the essential starting point theory, learn from the experience in the construction of relevant conceptual frameworks, start from the concept of the conceptual framework, clarify the main users of the report and their common needs, and combine the functions of the internal control evaluation report.Then, determine the objectives of the internal control evaluation report.This paper proposes that the introduction of information quality characteristics, elements of internal control evaluation reports, and cost-benefit measurement concepts can achieve the preset goals of enterprise internal control evaluation reports.

Accurate Detection of Intelligent Running Posture Based on Artificial Intelligence Sensor

In order to solve the problem of low accuracy of human posture recognition during motion, the author proposes a human posture recognition and detection method based on multiple sensors.The method uses acceleration sensor, angular velocity sensor, and single-chip microcomputer to collect data; uses time domain and frequency domain analysis methods to analyze the collected data; and then uses bayesian classifier to classify and identify the current motion posture of the human body.The obtained results are as follows: in the traditional method, with the increase of subjects, the accuracy of the classification method continues to decline; when the number of subjects reaches 50, the accuracy rate is only 60%; in the experiment, the zero crossing times of the acceleration signal axis are selected, and the axis area of the angular velocity signal is used as the characteristic item to distinguish the two different attitudes of going upstairs and going downstairs; the discrimination can reach about 90%.The authors combine the data collected by the acceleration sensor and the angular velocity sensor to perform feature extraction and classification, and the classification accuracy can reach more than 95%.It is proved that the method proposed by the authors can perform human gesture recognition very quickly and has a high accuracy rate.

The Application of a Multidimensional Prediction Model in the Recurrence of Female Pelvic Organ Prolapse after Surgery

The relationship between multiple indicators of women and postoperative recurrence of pelvic organ prolapse was analyzed to establish a model for predicting postoperative recurrence of female pelvic organ prolapse.Methods.Three hundred patients with pelvic organ prolapse who underwent pelvic organ prolapse surgery at our hospital were monitored for 1-2 years to determine their prognosis.Whether there was a postoperative recurrence, they were divided into two groups.We collected the relevant data from the two groups of patients before and after surgery.Through single factor and logistic multivariate analysis, we selected the risk factors that may affect the recurrence of patients to construct a prediction model.We verified the identification ability, proofreading ability, and clinical applicability of the model.Results.Eighty-four patients with pelvic organ prolapse who had postoperative recurrence were assigned to the recurrence group, and 216 patients were included in the nonrecurrence group.Based on the logistic multivariate analysis results, we constructed a nomogram model containing 5 dimensions of age, bmi, degree of prolapse, pubic fissure, and serum calcium to predict postoperative recurrence.The tests revealed that the model had an excellent identification ability ( auc = 0.910 ), and the expected recurrence rate was significantly in agreement with the actual recurrence rate ( u = − 0.007 , brief = 0.087 ).The hosmer-lemeshow goodness-of-fit test demonstrated that the model had good calibration ( c 2 = 29.352 , p = 0.522 ), and the decision curve showed that the threshold probability was in the range of ~12% to 100%, having a high net benefit value.Conclusion.Based on the present study findings, we concluded that the constructed nomogram model has suitable identification, calibration, and clinical applicability.

Study on Mechanical Characteristics of Energy-Absorbing and Anti-Scour Bolts

In order to improve the impact resistance and mechanical performance of anchor rods and satisfy the requirements for supporting rockburst roadways, the energy balance equation of the energy‐absorbing support and roadway surrounding rock system is established.Moreover, to effectively prevent rockburst disasters, the energy criterion for roadway instability is derived.From the perspective of an energy‐absorbing support, a yield‐absorbing anti‐shock anchor composed of a rod body, tray, constant resistance energy‐absorbing device, and special‐shaped nut is designed and developed; compared with ordinary anchor rods, this rod has stronger mechanical properties for resisting impact.Theoretical and numerical simulation studies show that the energy‐absorbing device has a repeatable deformation failure mode and a constant yield force.The paper also presents the principle involved in the design of anti‐shock bolt supports.The energy‐absorbing support not only effectively guides and controls the release and conversion of impact energy but also consumes the impact energy in the buffering process of the anchor to ensure the stability of surrounding rock and support protection system.This study aims to provide reference for roadway support design and to improve rock bolts used in rockburst roadways.

Study of the Structure and Properties of ZnS Utilized in a Fluorescence Biosensor

Zn s materials have been widely used in fluorescence biosensors to characterize different types of stem cells due to their excellent fluorescence effect.In this study, zn s was prepared by vulcanizing nano-zn particles synthesized using a dc arc plasma.The composition and structure of the zn s materials were studied by x-ray diffraction (xrd), and their functional group information and optical properties were investigated by using ir spectrophotometry and uv-vis spectrophotometry.It has been found that the synthesized materials consist of zn, cubic zn s, and hexagonal zn s according to the vulcanization parameters.Crystalline zn s was gradually transformed from a cubic to a hexagonal structure, and the cycling properties first increase, then decrease with increasing sulfurization temperature.There is an optimal curing temperature giving the best cycling performance and specific capacity: the material sulfurized thereat mainly consists of cubic β-zn s phase with a small quantity of zn and hexagonal α-zn s.The cubic phase zn s has better conductivity than hexagonal zn s, as evinced by electrochemical impedance spectroscopy (eis).The zn s (as prepared) shows board absorption, which can be used in fluorescence biosensors in cell imaging systems.

Statistical Characteristics and Security Analysis over Multi-Cascade κ-μ Shadowed Channels

In this paper, the statistical characteristics of the multi-cascade κ-μ shadowed fading channels are investigated and analyzed under the classic wyner’s eavesdropping model.In particular, the general accurate expressions of the probability density function and the cumulative distribution function for amplitude and signal-to-noise ratio (snr) are derived for the first time.Moreover, we further utilize the two performance evaluation metrics including outage probability and intercept probability to investigate the impacts of cascade number and channel parameters on reliability and security.Finally, the theoretical results are consistent with the simulations, proving the correctness of the derivation.The interesting conclusion is that when the average snr is greater than 2 d b, the reliability of the multi-cascade model will decrease as the number of cascade increases; on the contrary, more cascading can lead to stronger anti-eavesdropping ability.

Sports Augmented Cognitive Benefits: An fMRI Study of Executive Function with Go/NoGo Task

Exercise is believed to have significant cognitive benefits.Although an array of experimental paradigms have been employed to test the cognitive effects on exercising individuals, the mechanism as to how exercise induces cognitive benefits in the brain remains unclear.This study explores the effect of dynamic neural network processing with the classic go/no go task with regular exercisers.We used functional magnetic resonance imaging to analyze the brain activation of areas involved in executive function, especially inhibitory control.Nineteen regular joggers and twenty-one subjects as a control group performed the task, and their brain imaging data were analyzed.The results showed that at the attentive visual period, the frontal and parietal areas, including the prefrontal cortex, putamen, thalamus, lingual, fusiform, and caudate, were significantly enhanced in positive activities than the control group.On the other hand, in the following inhibitory control processing period, almost the same areas of the brains of the exercise group have shown stronger negative activation in comparison to the control group.Such dynamic temporal response patterns indicate that sports augment cognitive benefits; i.e., regular jogging increases the brain’s visual attention and inhibitory control capacities.
