Recently, CM at Risk delivery system(CM@R) that could solve the problems of Design Bid Build delivery(DBB) system has been emerging. In the CM@R delivery system, the contractor negotiates for a maximum guaranteed price(GMP) with the client at the design stage, and the contractor carries out the construction within the GMP. In CM @ R, the construction company with expertise in construction participates from the design stage to reflects the construction know-how in the design. On the other hand, the modification design frequently occurs due to the change of the construction cost when negotiating the GMP. In addition, uncertainties are inherent in the GMP calculation because the calculation is based on unfinished drawings and documents. This study proposes a probabilistic GMP estimation method applying MCS to the BIM - based cost prediction model, in order to extract the accurate quantity information when estimating the GMP and to cope with the change of the construction cost inherent in uncertainty.

The automated assignment of multiple tasks to executing agents is a key problem in the area of multi-agent systems. In many domains, significant savings can be achieved by reallocating tasks among agents with different costs for handling tasks. The automation of task reallocation among self-interested agents requires that the individual agents use a common negotiation protocol that prescribes how they have to interact in order to come to an agreement on "who does what". In this paper, we introduce the multi-agent Traveling Salesman Problem(TSP) as an example of task reallocation problem, and suggest the Vickery auction as an interagent negotiation protocol for solving this problem. In general, auction-based protocols show several advantageous features: they are easily implementable, they enforce an efficient assignment process, and they guarantce an agreement even in scenarios in which the agents possess only very little domain-specific Knowledge. Furthermore Vickrey auctions have the additional advantage that each interested agent bids only once and that the dominant strategy is to bid one′s true valuation. In order to apply this market-based protocol into task reallocation among self-interested agents, we define the profit of each agent, the goal of negotiation, tasks to be traded out through auctions, the bidding strategy, and the sequence of auctions. Through several experiments with sample multi-agent TSPs, we show that the task allocation can improve monotonically at each step and then finally an optimal task allocation can be found with this protocol.

Systematic studies on the dispatch scheduling algorithm and related constraints can enhance the effectiveness of electricity market operation. When System Operator (SO) establishes a dispatch schedule, the bid information should be preserved in the schedule as much as possible. In this paper, we introduce a new type of sensitivity factor called Line Outage Impact Factor (LOIF) to screen a transmission line causing the most severe outage when scheduling the dispatch. This screening can assure the stable system operation and make an efficient feedback between the SO and market participants. We propose a transmission line contingency constrained Pre-dispatch algorithm using sensitivity indices in a suitable Pre-dispatch scheduling. The proposed algorithm has been tested on sample system and the results show more secure operation against critical contingencies.

In the evaluation for ordering BIM-based projects (Design Build) of Korean National Railway, criteria of BIM-based smart construction technology are assessed. Unlike the existing assessment criteria, performance resources and detailed assessment guidelines have been added by this research. The purpose of this study is to propose qualification assessment standards according to specific guidelines when evaluating on the phase of bidding for BIM-based projects. In the study, an improved evaluation standard (draft) was arranged based on two consultation meetings and surveys of related companies, applied to existing projects with the companies that won the bid, and validated. As more specific and added criteria compared to the existing standards, it could reduce the difficulty of evaluation for BIM capability and lay the foundation for railway BIM-based project management.

The current web implementation largely falls into process-oriented and object-oriented methods. Both ways implement the programs to be used for simple design of external outfit and auxiliary function of hybrid webs and it might lead to cost problems arising from waste of time and man-power to develop with it. Therefore, managed structural system programming which can be applied under .NET framework is suggested in a bid to solve these problems. The structural system design method under .NET environment by applying CS concept prefers to adopting the optimized design configuration suited to proper interfaces of UI configuration, which offers the environment to maintain the inheritance relationship by taking form of the balanced class allotment by domain, and continue to keep the connectivity between UX and UI which leads to application of interface of UX objects as form of objects through connection with objects in class design process. This development method enables programs to be implemented focused on representation methods of UI and UX, and helps relieve much of the burden on development costs.

The purpose of this study was to examine support for education informatization provided by the government agencies and the private sector in a bid to give some suggestions on education informatization, as the three-stage education informatization plan was soon going to be completed. And it's found that the government agencies pushed ahead with the education informatization plan to boost national competitiveness, and their policies primarily focused on coping with the dysfunction of informatization and narrowing information divide. On the contrary, the private sector moved ahead with the plans that aimed at building necessary infrastructure in underdeveloped areas and providing various sorts of support involving education to the low-income classes.

Objectives : The purpose of this study was to examine the self-rated oral health concern of adults over the age of 20 and from all over the country and their subjective oral health symptoms in a bid to provide some information on oral health policy setting for adults. Methods : The subjects in this study were 3,558 adults who voluntarily participated in a survey conducted by this researcher at the website of a company. After their answer sheets were analyzed, the following findings were given: Results : 1. 81 percent replied that they were very concerned about oral health. As to the relationship between their general characteristics and oral health concern, there were statistically significant differences in that regard according to their gender, age, purpose of seeing a dentist and occupation. 2. As for the relationship of their general characteristics to subjective awareness of oral health symptoms, there were statistically significant gaps in that aspect according to their gender, age, purpose of seeing a dentist, occupation and state of smoking. 3. In regard to the relationship between oral health concern and subjective awareness of oral health symptoms, those who were more concerned about oral health felt less subjective oral symptoms, but the difference between them and the others was not significant. The respondents who felt more symptoms of dental caries felt more symptoms of periodontal diseases as well. Conclusions : The above-mentioned findings indicate that in order to help adults promote or maintain their oral health, their concern for oral health should be stimulated by providing them with a lot of diverse information, and it seems that the development of programs that can eliminate their subjective oral symptoms of dental caries and peridontal diseases, the primary causes of tooth dysfunction, is required.
