Rising co.plexities in co.struction projects management has boosted the importance of relationa co.tracting(RC) in the field. RC is based on reco.nition of mutual bene fits and win-win scenarios gained through more co.perative relationships between co.tracting parties There have been a range of RC initiatives across many co.ntries towards deeper co.laborative relationships; however, such formal RC approaches are not yet wel established in china. In this paper, the feasibility of implementing RC in the china's public co.struction projects is investigated. The results indicate that RC is highly feasible for implementation in china due to its theoretical bene fits, its alignment to Chinese culture, and its behaviors in past public co.struction projects. three strategies for facilitating the implementation of RC in china are proposed.

By co.bining sequencing batch reactor (SBR) activated sludge process and co.structed wetland (CW), this study is to achieve the domestic wastewater treatment. Our purpose was to determine the optimum operating parameters of the co.bined process. The process involved advantages and shortages of SBR and CW. Under normal temperature, the 3rd cycle (SBR’s operation cycle is 8 h: inflow for 1 h, limited aeration for 3 h, sediment for 1 h, outflow for 1 h, and idling for 2 h; CW’s hydraulic retention time (HRT) is 24.8 h and hydraulic loading is 24.5 m3/m2 d) was the best cyclic mode. The effluents can meet the standard GB/T18921-2002: "The reuse of urban recycling water: water quality standard for scenic environment use". In the 3rd cycle, the efficiency of CW was the maximum, and energy co.sumption of SBR was the minimum. Under the co.dition of low dissolved oxygen, the removing efficiency of chemical oxygen demand (co.) and ammonia was not affected obviously. Simultaneously, nitrification and denitrification phenomena occured and phosphorus was absorbed obviously.

Background Over 10 million Chinese are affected by schizophrenia. The annual co.t of schizophrenia in china was estimated at US$2586 per *** The study has two aims:(1) to co.duct a targeted literature review of the eco.omic literature on oral ziprasidone in china, and(2) to develop an inpatient eco.omic model that co.pared the co.t of intramuscular ziprasidone with other regimens including electroco.vulsive therapy(ECT) for the management of acute agitation in patients with schizophrenia from a hospital's perspective in *** A targeted literature review was co.ducted using PubMed and the Chinese literature databases for studies published between January 2007 and December2017. Studies that assessed co.ts associated with oral ziprasidone treatment for schizophrenia in china were summarised. In the inpatient eco.omic model,co.t measures included hospital room and board,antipsychotics,ECT and medications for the management of extrapyramidal symptoms(EPS). Input for standard antipsychotic regimens and unit co.t were obtained from the literature. Hospital length of stay(LOS), utilisation of ECT and incidence of EPS were derived from the literature and supplemented/validated with a survey of psychiatrists in china. co.t was presented in 2017 Chinese *** The average estimated LOS was 29 days with ziprasidone, 33 days with risperidone+benzodiazepine,32 days with olanzapine, 35 days with haloperidol and 29 days with ECT. The co.t of antipsychotics was $1260 with ziprasidone, $137 with risperidone+benzodiazepine, $913 with olanzapine and $210 with haloperidol; ECT treatment co.ts $785. The base-case analysis suggested that higher antipsychotic co.t with ziprasidone was offset by savings with shorter LOS. Using intramuscular ziprasidone for acute management was associated with a total co.t of $11157, the lowest among all antipsychotic regimens($11 424 with risperidone+benzodiazepine, $11 711 with olanzapine and $11 912 with haloperidol) and slightly h
