The outrigger damper system is a structural system with excellent lateral resistance when a wind load occurs. However, research on outrigger dampers is still in its infancy. In this study, dynamic response control performance of damper is analyzed according to change of stiffness value and damping value of damper. To do this, a real-scale 3D model of 50 stories has been developed and the artificial wind load has been entered for dynamic analysis. Generally, the larger the damping value, the smaller the stiffness value is, the more effective it is to reduce the maximum displacement and acceleration response. However, the larger the attenuation value as the cost of construction increases, it is necessary to select appropriate stiffness and damping value when applying an outrigger damper.

In recent years there have been many efforts for changing from machine oriented technology to human oriented technology gradually. In the research of Intelligent system, the previous simple learning and reasoning methods are also changing to human like processing, namely the direction of implementing humanity. Especially as Neuro Engineering research is getting active, the studies on application of brain function are increasing in the engineering aspects. In this paper, we defined Super Value as a concept which reflect the higher value of 'viewpoint' and proposed flexible KEB(Knowledge-Emotion Binding) System. The system has a hierarchical structure which consists of Main level and Super level for flexibility and it is designed for having the function of extracting KEB Threads by Reasoning mechanism.

This paper shows the architecture of IPS(Intermarket Payment System), an implementation of the electronic payment function for internet-shopping merchant system. Because the original purpose of commerce transaction is the exchange of money for goods or services, it is very important to prepare an exchangeable economic value or method. The electronic payment system is the hardware or software or both to process an electronic payment transaction. It has two type, the broker type and the electronic value type. The broker type means an intermediator between real bank network and internet commerce transaction. The electronic value type means a substitute for money in the real world. This paper shows the architecture and the function to implement the broker type electronic payment system. The system has two parts. One is the mediator part to support multiple payment systems and to offer common access methods for merchant system database. The other is the executor part to implement the payment protocol and to process payment transaction.

It seems that a primary concern of the project-based company, which provides a large scale product or service over long term period, is to run a successful project through systematic project process control and control costs. One of the typical project control methods is Earned Value Management System(EVMS) which analyses the precess through performance measurement. Even though the EVMS is a highly efficient tool in the managerial aspect, it cannot easily determine the Planned Value(PV), Actual Cost(AC), or Earned Value(EV) due to the indistinct criteria and extensive data. The accurate calculation of AC in particular, is the basic of project management, but most companies record direct personnel expenses or direct expenses only. Since they calculate indirect expenses based on the estimated ratio, it limits the systematic project management that reflects changes in profit and loss of a company. This study introduces a EVMS for project management and its actual case based on EVMS and ERP system which some additional modules are installed for performance measurement. It is expected that this new method enables a company to save time and effort, and also to improve transparency by specifying expense items in detail and to switch quarterly settlement to monthly by reducing the time of calculation.

How should the value of presidential records be evaluated and discarded? Currently, the evaluation of presidential records is operated in a dual system that evaluates the value of 7 types based on the characteristics of presidential records as public records while considering the uniqueness of presidential records. Once again, we have to think about 'where does the value of presidential records come from, and how can we evaluate this value'. In this paper, I would like to examine the value and evaluation of presidential records by understanding the characteristics of the domestic presidential archives evaluation system and organizing the problems and issues of the current evaluation system. In addition, the purpose of this study is to examine the evaluation system of presidential records stipulated in the Presidential Records Management Act of the United States and to analyze its implications for the domestic presidential records evaluation system.

The results of this study can be summarized as followings. First, healthcare accreditation system had not a positive significant on the job satisfaction. Second, healthcare accreditation system had a positive significant on service value. Third, job satisfaction had a positive significant on the organizational commitment. Forth, service value had a positive significant on the organizational commitment.

In this study, the effect of load torque on the synchronous whirling of a rotor system has been studied analytically. Results show that the critical value of load torque to damping exists above which synchronous response decreases with increasing load torque. It has been also shown that the synchronous whirling amplitudes are more sensitive to the value of eccentricity and the ratio of disk radius to shaft length of the rotor system than other design parameters for a fixed value of load torque.

This paper presents a method for establishing an initial value of redundancy optimization problem to maximize system reliability of multiconstraint mixed parallel-series system. The constraints not be linear. This paper proposes a new initial value which is near to optimal solution by considering the relative median rate of the unreliability and amount of consumed resources for each subsystem. To show the efficiency of this model. numerical example and comparison with Narasimhalu is illustrated in chapter 4.

Storytelling plays a very important role in emotional marketing recently. Storytelling marketing emphasizes a unique story and mythical meaning of the product, rather than its practical function. This is a faithful reflection of what the Dream Society has proposed. In this article, we are researching the consumption value system, and analyze various cases focusing on a coffee advertisement. In particular, by delivering a story, we will concentrate on advertising that appeals to utopian values and discusses the actual impact that it brings. If we communicate utopian values to consumers through various stories, business effects will be maximized, which will strengthen the brand image. The originality of this paper is to discuss the theory of consumption value system positively with the concept of storytelling. Therefore, we will draw conclusions as to which orientation is most ideal for storytelling in advertising. Understanding these business models will help you build an effective marketing strategy for the Dream Society.

In this paper, a new overload control scheme is proposed for a control system in ATM switching system. The proposed control scheme includes a counter that conunts the number of accepted calls and is decreased at cach D time interval. In overload condition of call processor, the control scheme detects over load condition when the counter value reaches a certain threshold value. Under overload condition, processor utilization is measured and the value of the D is updataed according to the difference between measured processor utilization and target utilization. A new call is accepted accepted only if the value of the counter is less than the threshold value. In overflow condition of cell traffic, accept probability of new call is reduced exponetially according to the elapsed time. The results of simulation show that the proposed overload contorl scheme maintains the target utilization very well under the various processor overload conditions and reduces the cell loss probability under the cell overflow conditions.
