Design optimization is an effective strategy to reduce construction project costs. This study focuses on the benefit of designoptimization, which should be allocated to the designer. Furthermore, the distribution ratio can be determined through negotiation. Inline with this view, this paper initially analyzed the benefits of engineering design optimization and the basic mechanism of itsdistribution. Second, we established the negotiation model of design optimization profit distribution by considering the fairnessconcern behavior of subjects. Finally, we set up the following three experimental scenarios: the designer solely has fairness concernbehavior, the owner exclusively has fairness concern behavior, and both negotiators have fairness concern behavior. From theengineering projects perspectives, we further analyzed the effects of the fairness concerns of both negotiators in terms of engineeringdesign optimization and negotiation performance using negotiation simulation experiments. Our experimental scenarios results showthat the appropriate behavior of fairness concerns by the two negotiators is valuable in improving their own advantages. However,excessive attention to the behaviors of fairness concerns by the two negotiators may lead to an increase in the negotiation cycle,which is not beneficial in attaining optimization. This study aims to provide references for the construction project management.

A core-shell surface-imprinted polymer was successfully synthesized on the surface of silica spheres by precipitation polymerization. The polymers were used to selectively identify dichlorophen in complex environmental system. The physical-chemical properties of the silica sphere molecularly imprinted polymers were analyzed by scanning electron microscopy and transmission electron microscopy scans characterization. The adsorption properties of core-shell polymers were examined by adsorption isotherms, kinetics and selectivity experiments. The Langmuir adsorption isotherm well fitted the adsorption experimental data, and an increase of temperature enhanced the adsorption capacity. The maximum binding capacity of imprinted polymers reached 72.46 mg g-1 at 318 K. Meanwhile, the adsorption data of binding experiments were well-fitting by the pseudo-second-order equation. Compared with nonimprinted polymer, the imprinted polymer not only has specific selectivity towards dichlorophen but also has higher adsorption performance. Moreover, via the regeneration experiments, it has been demonstrated that the MIPs have certain stability to the adsorption for the target, which provides a good reference for the adsorption of dichlorophen by the imprinted polymer in water.

Xiao Wei,Li Rui 한국여성철학회 2017 한국여성철학 Vol.28 No.-
From 2011 to 2015, it is the period of a rapid and fruitful development for feminist philosophy studies in China. According to the database of China National Knowledge Internet (CNKI), there are 377 articles with the key word of feminist philosophy to have been published in a number of journals in the period. Comparing to 267articles that were published in 2006-2010, the number of periodical articles increases 41%. This not only shows the concern and participation for Chinese scholars to study in feminist philosophy, but also embodies more systematically and richly in research methodologies and subjects, as well as their practical applications. This paper will be a review of the study of Chinese Feminist Philosophy under 8 sub-tittles,and try to analyze the achievement of feminist philosophy in the years 2011—2015 and look forward to the future possibilities for feminist philosophy studies in China.

Background/Aims: In recent years, endoscopic submucosal tunnel dissection (ESTD) has gained popularity worldwide. The aim of this study was to evaluate the safety and efficacy of ESTD in treating upper gastrointestinal submucosal tu-mors (SMTs) in a large-volume endoscopic center. Methods: Patients with SMTs were enrolled in this study between January 2012 and January 2015. Demographic data, clinical data, and treatment outcome were collected and analyzed. Results: Seventy SMTs originating from the muscularis pro-pria (MP) layer were identified in 69 patients. All patients successfully underwent the ESTD procedure. The mean procedure time was 49.0±29.5 minutes, and the mean tu-mor size was 18.7±7.2 mm. Among all lesions, the majority (70.0%) were located in the esophagus, 12.9% in the cardia, and 17.1% in the stomach. Complete resection was achieved in 67 lesions (95.7%). Perforation occurred in three patients (4.3%), who were treated by endoclips. Pneumothorax oc-curred in two patients (2.9%) and was successfully managed by thoracic drainage. During a median follow-up of 18.1 months, patients were free of local recurrence or distant metastasis. Conclusions: Our results demonstrated the fea-sibility and safety of ESTD in treating upper gastrointestinal SMTs originating from the MP layer. Large-scale comparative studies with other treatment methods should be conducted in the future. (Gut Liver 2017;11:620-627)
A Lightweight Three-Party Privacy-preserving Authentication Key Exchange Protocol Using Smart Card
( Xiaowei Li ),( Yuqing Zhang ),( Xuefeng Liu ),( Jin Cao ) 한국인터넷정보학회 2013 KSII Transactions on Internet and Information Syst Vol.7 No.5
How to make people keep both the confidentiality of the sensitive data and the privacy of their real identity in communication networks has been a hot topic in recent years. Researchers proposed privacy-preserving authenticated key exchange protocols (PPAKE) to answer this question. However, lots of PPAKE protocols need users to remember long secrets which are inconvenient for them. In this paper we propose a lightweight three-party privacy-preserving authentication key exchange (3PPAKE) protocol using smart card to address the problem. The advantages of the new 3PPAKE protocol are: 1. The only secrets that the users need to remember in the authentication are their short passwords; 2. Both of the users can negotiate a common key and keep their identity privacy, i.e., providing anonymity for both users in the communication; 3. It enjoys better performance in terms of computation cost and security. The security of the scheme is given in the random oracle model. To the best of our knowledge, the new protocol is the first provably secure authentication protocol which provides anonymity for both users in the three-party setting.

Due to the complex structure and wide excitations of range extender, the misfire and stator short-circuit coupling fault is easy to occur. Therefore, it is necessary to study the coupling fault mechanism of range extender, analyze the cause of the fault and the evolution law of fault, and diagnose the coupling fault through coupling fault characteristics ultimately. In this paper, a range extender is taken as research object. By establishing a nonlinear dynamic model and using Runge-Kutta method with variable step size, the dynamic response characteristics of system under different working conditions are analyzed to study the single fault and coupling fault mechanism. Then through the finite element analysis and practical experiments, the feasibility of coupled fault diagnosis is verified. The results show that when misfire fault and stator short-circuit fault occur at the same time, the vibration intensity of coupling fault is greater than that of single fault, and the 0.5- and 3.0-order harmonic amplitudes of horizontal vibration speed increase with the coupling fault.

In the present study, we identified genes that are putatively involved in the production of fungal 10-hydroxycamptothecin via transcriptome sequencing and characterization of the Xylaria sp. M71 treated with salicylic acid (SA). A total of 60,664,200 raw reads were assembled into 26,044 unigenes. BLAST assigned 8,767 (33.7%) and 10,840 (41.6%) unigenes to 40 Gene Ontology (GO) annotations and 108 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, respectively. A total of 3,713 unigenes comprising 1,504 upregulated and 2,209 downregulated unigenes were found to be differentially expressed between SA-induced and control fungi. Based on the camptothecin biosynthesis pathway in plants, 13 functional genes of Xylaria sp. M71 were mapped to the mevalonate (MVA) pathway, suggesting that the fungal 10-hydroxycamptothecin is produced via the MVA pathway. In summary, analysis of the Xylaria sp. M71 transcriptome allowed the identification of unigenes that are putatively involved in 10-hydroxycamptothecin biosynthesis in fungi.

( Xiaowei Hai ),( Chanchan Zhao ) 한국정보처리학회 2018 Journal of information processing systems Vol.14 No.2
The purpose of the high-speed railway construction is to better satisfy passenger travel demands. Accordingly, the design of the train working plan must also take a full account of the interests of passengers. Aiming at problems, such as the complex transport organization and different speed trains coexisting, combined with the existing research on the train working plan optimization model, the multiobjective bi-level programming model of the high-speed railway passenger train working plan was established. This model considers the interests of passengers as the center and also takes into account the interests of railway transport enterprises. Specifically, passenger travel cost and travel time minimizations are both considered as the objectives of upper-level programming, whereas railway enterprise profit maximization is regarded as the objective of the lower-level programming. The model solution algorithm based on genetic algorithm was proposed. Through an example analysis, the feasibility and rationality of the model and algorithm were proved.
