Mechanism Construction of Human Resource Management based on Blockchain Technology

The traditional human resource management system is faced with such problems as the quality of staff recruitment can not be guaranteed,the training performance is not consistent with the actual performance,the enterprise performance appraisal is unfair,and the salary distribution is unfair,which seriously affects the enthusiasm and loyalty of employees and threatens the survival and development of enterprises.In view of the current situation and problems of human resource management system,combined with the technical characteristics of blockchain,this paper proposes a human resource management mechanism based on blockchain technology,in order to achieve the company’s human resource management system accurate,efficient,open and transparent.It is found that there is a good coupling between blockchain technology and human resource management system.This paper constructs a human resource management mechanism based on blockchain,innovates the application scenarios of blockchain technology,and provides certain guiding significance for the establishment of human resource management system and process improvement in the future.

Analysis on Post-Abortion Care Service Mechanism Construction and Popularization

In view of current situation of high repeated abortion rate in China, the Chinese Women＇ s Development Foundation, the Family Planning Branch of Chinese Medical Association and the National Population and Family Planning Science and Technology Research Institute mutually sponsor the ＂Caring Her Care after Abortion（abbreviated as PAC） Public Welfare Project＂ , aiming at establishing PAC excellence service model outpatient service, regulating the female care service process after abortion, promoting contraception knowledge, strengthening the immediate contraception consciousness after abortion, implementing effective contraception measures and guiding females how to adhere to the correct usage after abortion, so as to improve the female reproductive health level.

An Exploration of the Construction of Inner Driving Force of Cultural Education in Vocational Colleges

Cultural education is closely related to individual development and the needs for economic,social,and technological development,which,while aiming at improving students’overall professionalism,respects their subjective consciousness and initiative,highlights the development of personality and individual potential,and designs and improves educational activities that are characterized by cultivating people’s ability to make innovation,start a business,and form a healthy personality.Taking problems existing in the cultural education in vocational colleges as the cutin point,this paper explored the inner driving force of cultural education in the new era and tried to discuss the concept,objectives,content and mechanism of cultural education by pivoting to individual autonomy,expertise,and development goals,with the hope that the inner driving force of cultural education could be effectively carried out.

Study of slope topple mechanism on belt express way around Jilin City

The Slope Program is a complex problem,and the constructive mechanics is the emphasis and difficult point of the slope researching.The research on the slope constructive mechanics takes an important theory and experience role of the stability analysis and preventive methods.On the basis of the field survey of the overturn-slope on the Jilin Belt Highway,the authors analyzed its constructive mechanics,valuated its stability,and showed the treatments of the slope.

Model Test for Dynamic Construction Mechanical Effect of Large-Span Loess Tunnel

It has been a focus of debate for a large time on construction methods for large-span loess tunnel.Reasonable construction method has much effect on stability of tunnel and construction schedule.Deformation and failure of surrounding rock are quite complex.Associating with the large-span loess tunnel of Zhengzhou- Xi'an high-speed passenger rail line in China,large scale model test with geometric proportion 1:20 is applied to study on dynamic mechanical behavior of various construction methods.They include full-face excavation with support and no support,and benching method with support.It is found that pre-deformation and stress accumulation take place ahead of working face.The effects of three construction methods are further studied,particularly in terms of tunnel displacement and stress changes.It is revealed that benching method transfers load to an unexcavated area,limits horizontal deformation,reduces stress concentration effectively,lengthens the distance between location of peak for stress concentration and working face,and consequently increases stability.The model test results not only supply theoretical foundation for determination of reasonable construction method,but also can act as reference for similar tunnel and underground engineering construction.

Modular construction mechanics of a European pressurized reactor steel containment liner

A European pressurized reactor （EPR） steel containment liner structure is comprised of the cylinder part and the dome part. An introduction of the steel liner structure is presented, followed by studies on the key mechanical features of the construction process using a refined finite element method. The steel liner was divided into several modules and then assembled during construction. Firstly, the equipment structure used to hoist the liner module was optimized, the lifting lug was analyzed using a multi-scale finite element model; the wind speed limit during lifting was also studied. Subsequently, the effect of internal forces during assembly between the liner modules, the lateral pressure of fresh concrete, the non-uniform temperature load, and the wind load on the cylinder module was analyzed. According to the time-varying structural performance during continuous concrete pouring and the hardening construction, an ＂overlapping element and birth-death element＂ technique was adopted to analyze the deformation and stress of the long-span steel dome liner. In addition, the stability-bearing capacities of the dome structure during construction were also studied, which took into consideration the effect of the initial geometrical imperfections and the elasto-plasticity of the material. This study presents a reference in terms of the mechanics of the construction scheme and the safety of such a type of structure.
