It identifies opportunities to remove unnecessary costs while assuring that quality, reliability, performance, and other critical factors will meet or exceed the customers’ expectations. It has been widely used in the construction industry in a number of countries. A recent survey, however, revealed several problems that hinder the wider use of this methodology in the industry. To overcome these problems, a feasibility study has been conducted to investigate whether or not a Group Support System (GSS) can support collaborative works in VM workshops. This paper introduces the development and structure of a prototype GSS which is designed to support the collaborative works of stakeholders in VM workshops. It begins with an introduction to the conceptual GSS framework and job plan, illustrating what GSS supports can be provided to VM workshops. This is followed by a detailed description of the GSS prototype system to demonstrate how these supports can be performed as an integrated computer system. The testing of the system is also discussed. The research findings provide strong evidence in supporting the notion of using GSS to improve VM implementation. The information support of GSS has been ranked to be the most useful GSS functions and most of the practitioners interviewed are highly interested in applying GSS to support VM workshops in the future.展开更多

This kind of framework includes four basic layers, namely, application layer, task layer, logical layer and physical layer. Based on indicating the respective meanings of those layers a task skeleton of group decision support system and a logical structure of group decision support system generator are put forward and discussed in detail. The framework provides theoretical guidance for developing group decision support system to lower systematic development complexity and support reuse of software.展开更多

In Cameroon, the viral load (VL) suppression rate is 44.7% and poor adherence is widely documented as being responsible for the large gap in VL Suppression. Enhanced adherence counselling (EAC) sessions, and enrolment and participation in support groups are specific interventions to improve ART adherence and improve viral load suppression. Purpose: This study assesses the uptake and contribution of support groups and EAC sessions in the management of adolescents with unsuppressed VL results at Centre Hospitalier d’Essos, Yaounde. Methods: A retrospective correlational quantitative patient files review was conducted for 138 files of HIV positive adolescents aged between 10 - 19 years with HIV VL above 1000 copies/ml enrolled in care between January 2009 and December 2019. Data from the questionnaire was entered into CSPRO version 7.4. and analyzed by using SPSS version 25.0. Results: A total of 138 participants (75 females and 63 males) with a mean age of 15 ± 3 years were included in our study. Sixty-nine (50%) participants were in World Health Organization (WHO) stage I;32.6% were in Stage II;13.0% and 4.3% were in stages III and IV, respectively. Thirty (21.7%) had a history of tuberculosis and 76% of the adolescents were being cared for primarily by their parents. The charts of the adolescents revealed that there was an association between completion of EAC sessions in adolescents with unsuppressed VL and eventual VL suppression (R.R = 2.5;CI 0.848 - 6.162;p = 0.033). However, there was no significant association between support group enrolment and active participation, and eventual VL Suppression. Furthermore, combining EAC and support group interventions was strongly associated with eventual VL Suppression in this group of initially unsuppressed adolescents (R.R = 7.5;C.I 2.544 - 22.360;p Conclusion: Suppression rates were good after completion of EAC sessions and participation in support group enrolment for adolescents with a high VL. As we move towards having 95% of ART-treated adolescents achieve and maintain viral suppression, there is a need to reinforce EAC sessions and support group enrolment in ART clinics targeting this priority group.展开更多

The evaluating problem is becoming one of the popular issues in academe. In this paper, the essential meaning of evaluation is defined firstly, and evaluation process analyzed: putting forward the problem of evaluation; defining evaluation subject, evaluation organizer and evaluation criterion and method; processing and feeding back evaluation results. According to the essential meaning and process, the evaluation support system (ESS) is established, consisting of four function modules: problem definition module, data extraction module, mold database module and man-machine communication module. Based on the complexity of factual problem, the group evaluation support system(GESS) is established, which is an integration system of many valuators’ wisdom, experience and corresponding ESS. GESS is used to support group valuators to solve semi-construction evaluation problem on the basis of computer and network in order to acquire scientificity and objectivity in the evaluation of big system.展开更多

From the beginning, there are biographical notes made about the most well-known fan leaders in Rio, such as Jaime de Carvalho, who founded the Charanga （1942）. The emergence of dissent among the fans, in the late 1960s, is then covered, which establishes itself within the organized fans in Rio with these individuals beginning to question the authority of the old fan group leaders. This is against the principle of giving unconditional support to the club and it is postulated that the fans have the right to criticize and protest against the club＇s management, even if this means using forceful tactics. Along with the journalistic narrative, there is a break-off by the ＂Young Fans＂ and a process of emancipation begins which occurs over the 1970s, this happens by means of the use of fan coaches and the invention of a lifestyle that is associated with soccer. Finally, the 1980s is marked by the constructive and destructive potential that is linked to fan groups. On the one hand, creating an Association of fans--Astorj--is pointed to in order to reach a mutual understanding, but it should be noted, on the other, that there are feuds, in a scenario of spiraling violence, in which fights, beatings, and even murders begin to be commonplace.展开更多

Pig models of acute hepatic failure were induced by D-galactosamine and randomly divided into two groups with or without artificial liver support system treatment. Tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β） levels were detected by the enzyme linked immunosorbent assay （ELISA）, the expression of HMGB-1 by Western blot, and serum levels of HMGB-1, liver function and hepatic pathology were observed after artificial liver support system treatment. The levels of TNF-α and IL-1β were increased and reached the peak at 24th h in the acute hepatic failure group, then quickly decreased. The serum level of HMGB-1 was increased at 24th h in the acute hepatic failure group and reached the peak at 48th h, then kept a stable high level. Significant liver injury appeared at 24th h and was continuously getting worse in the pig models of acute hepatic failure. In contrast, the liver injury was significantly alleviated and serum level of HMGB-1 was significantly decreased in the group treated with artificial liver support system （P〈0.05）. It was suggested that HMGB-1 may participate in the inflammatory response and liver injury in the late stage of the acute liver failure. Artificial liver support system treatment can reduce serum HMGB-1 level and relieve liver pathological damage.展开更多

文摘Recently we develop a new conceptual model for group decision support Systems. Themodel is based on the information communication theory, minority ducting theory and human physicaland mental limited theory described by Srinvasan & Sirkkal(1991)[1]. The new model tells how to reducethe noise and enhance the information communication and then enhance GDSS function; it tells howto provide the minority effect to enhance GDSS function; it tells how to reduce knowledge resourceconsumption and enhance knowledge resource and enhance GDSS ability. The authors developed thenew GDSS system in LAN and WAN environment.
