The traditional theories of games are based on an assumption that the payoffs have a single dimension. In reality, any alternative is likely to imply more than one payoff. This paper deals with the game against nature with vector payoffs. The purpose of this paper is to develop methods for finding the practical optimal strategy in the game against nature with vector payoffs. Under the assumption that a prior probability over the stats of nature is given, this paper shows that a practical optimal strategy in this game can be obtained by applying a entropy method in order to assess the payoff weight and by employing the concept of compromise solutions in order to reduce the non-dominated solutions. When subjective payoff weights are unknown as well as known, these methods can be used. A numerical example is given.

Base isolation is a quite practical control strategy for enhancing the response of structural systems induced by strong ground motions. Due to the dynamic effects of base isolation systems, reduction in the interstory drifts of the superstructure is often achieved at the expense of high base displacement level, which may lead to instability of the structure or non-practical designs for the base isolators. To reduce the base displacement, several hybrid structural control strategies have been studied over the past decades. This study investigates a particular strategy that employs Tuned Mass Dampers (TMDs) for improving the performance of base-isolated structures and unlike previous studies, specifically focuses on the effectiveness of this hybrid control strategy in structures that are equipped with nonlinear base isolation systems. To consider the nonlinearities of base isolation systems, a Bouc-Wen model is selected and nonlinear dynamic OpenSees models are used to perform several time-history simulations in time and frequency domains. Through these numerical simulations, the effects of several parameters such as the fundamental period of the structure, dynamic properties of the TMD and isolation systems and properties of the input ground motion on the behaviour of TMD-structure-base isolation systems are examined. The results of this study provide a better insight into the performance of linear shear-story structures with nonlinear base isolators and show that there are many scenarios in which TMDs can still improve the performance of these systems.

The purposes of this study were to investigate the current status on stating a summary of assessments in the practical arts education and to analyze the problem and find out the reformation strategy for them. To achieve these purposes. 180 teachers working in all elementary schools located in Daegu-city was selected by systematic cluster sampling method. The data were collected by using the mailed questionnaire developed by the researcher, and there was a response rate of 91.7%. Findings showed that it was not realized the valid and reliable stating a summary of assessments because it was not fixed throughly in the elementary school. So many teachers had difficulties in assessing the practical arts subject and stating a summary of assessments. They used the computer programs of CMI(Computer Management Instruction) . Black Box. SA(Stand Along) for stating a summary of assessments. It was recommended that valid and reliable criteria of stating a summary of assessments should provided, and on-the-job training on the developing and selecting a good tools for stating a summary of assessments should required. And. it was also required that the various codes of stating a summary of assessments should developed. and the various materials. equipments. and systems should provided for teachers.

In this study, a new strategy is presented to transmit the fundamental elastic beam problem into the modern optimization platform and solve it by using artificial intelligence (AI) tools. As a practical example, deflection of Euler-Bernoulli beam is mathematically formulated by 2nd-order ordinary differential equations (ODEs) in accordance to the classical beam theory. This fundamental engineer problem is then transmitted from classic formulation to its artificial-intelligence presentation where the behavior of the beam is simulated by using neural networks (NNs). The supervised training strategy is employed in the developed NNs implemented in the heuristic optimization algorithms as the fitness function. Different evolutionary optimization tools such as genetic algorithm (GA) and particle swarm optimization (PSO) are used to solve this non-linear optimization problem. The step-by-step procedure of the proposed method is presented in the form of a practical flowchart. The results indicate that the proposed method of using AI toolsin solving beam ODEs can efficiently lead to accurate solutions with low computational costs, and should prove useful to solve more complex practical applications.

Cost, schedule, and quality are the three major performance indicators for any construction project. Under the globalized competition in the nuclear industry, researchers and practitioners have also explored a systemized and integrated management system for cost, schedule, and quality. In order to address this issue, the concept of earned value management system (EVMS) has been often utilized. However, implementing EVMS for a mega-project of nuclear power plant (NPP) construction requires extensive overhead efforts. Though previous studies proposed structures and methods for effective NPP EVMS, there has been no legitimate study for data collection strategy for practical implementation. In this context, the purpose of this paper is to develop an effective data collection strategy for NPP EVMS. Firstly, the barriers to practical NPP EVMS were identified based on literature review and expert interviews. Strategies for data collection were then developed based on different phases of project life cycle. This study focuses on the 'life-cycle integrated progress management system' for NPP construction from an owner's perspective Therefore, results of this study can be used as a guide for preparing request for proposals (RFP) of an NPP owner organization.

This research is, first of all, a theoretical study concerning 'conflict.' Only then, we could obtain ways in which we manage and resolve various problems arising from conflicts in business between Korean and Chinese companies. In doing this, we also tried to grasp cultural characteristics, or factors, in Chinese ways of carrying out negotiations that lead to conflicts with us. On the basis of these preliminary considerations, we developed practical techniques of conflict management and types of negotiation strategy. We thereby could suggest broader strategic implications for better performance in international business. Concretely, this research investigates techniques of conflict management and types of negotiation strategy. For such techniques and types, we suggest, (1) Sharing technique or reconciliatory compromising negotiation and its compromise strategy, (2) collaborative technique or cooperative negotiation and its win-win strategy, (3) competitive technique or competitive negotiation and its profit-seeking attack strategy, (4) accommodative technique or receptive negotiation and its relation-maintaining yield strategy, (5) avoidant technique or evasive negotiation and its indifference-showing avoidance strategy. This research contributes to promote understanding on negotiation culture of chinese corporate. and we provide the guideline of the conflict management and the insight for the efficiency strategy of chinese business negotiation. But, empirical data and statistical examinations should be added to our present research for the future prospective ones.
