In this paper, the necessity of developing effective nondestructive testing and monitoring techniques for the evaluation of structural integrity and performance is described. The evaluation of structural integrity and performance is especially important when the structures and subject to abrupt external forces such as earthquake. A prompt and extensive inspection is required over a large area of earthquake-damaged zone. This evaluation process is regarded as a part of performance-based design. In the paper, nondestructive testing and monitoring techniques particularly for concrete structures are presented as methods for the evaluation of structural integrity and performance. The concept of performance-based design is first defined in the paper followed by the role of evaluation of structures in the context of overall performance=based design concept. Among possible techniques for the evaluation, nondestructive testing methods for concrete structures using radar and a concept of using fiber sensor for continuous monitoring of structures are presented.

This study analyzes the buyer's remedies for defects in title under DCFR, and it is compared with those of CISG. DCFR adopts a unitary concept of 'non-performance' which is any failure and includes delayed performance and any other performance which is not conformed with the contract. In terms of defects in title, any remedies for non-performance are available under DCFR. Thus. under DCFR, the buyer is entitled to enforce specific performance of obligations, to withhold performance, to terminate for fundamental non-performance, to reduce price, to damage for loss, to require repair, or to deliver a replacement. But under CISG, whether or not defects in title constitute 'non-conformity' is not clear and the majority understands 'non-conformity' does not include title defects. Therefore, the buyer may not has rights to require repair and delivery of replacement unlike DCFR.

In spite of IT performance can be achieved through the interaction of IT and organization, many previous study has been treated the introduction of the information system itself as a final outcome. But if it doesn't clear about understanding on IT performance, performance management is difficult and also it is impossible to produce the intended outcomes. This study investigates the improvement of the business performance of SMEs through IT investment, whether the investment process on business performance. Analytical methods that were used in previous studies were maintained and new model IO(Information Orientation) analysis was applied. Therefore, this study is meaningful to establish a new methodology, that is not attempted until now, for evaluating the performance of IT investment, and analysis relationship between IT investment and business performance.

In order to plan and manage public facilities effectively and efficiently, it is necessary to diagnose the current status of facilities and decide the objective features. Performance measurement is to provide managers with the information they need to measure competitive advantages. This paper discusses public facility performance in order to establish the conceptual framework for performance measurement for public facilities. In order to develop the measurement of public facility performance, a pilot study was conducted with facilities managers of facilities management corporation of public districts in Seoul. We investigated how public facilities management teams have assessed their performance and collected data regarding financial aspects, service aspects, community aspects, and building aspects. There is no standard format to measure facility performance since building sizes, programs, community needs widely differ. However, it is necessary to have a more consistent system to measure facility performance. In addition, each public municipal district needs to empower each district facilities management corporation to participate in managerial decisions and budget control.

This study is to explore the relationship between trust in local administrative organization and organizational performance. Local administrative organizations provide the citizens with administrative services. Heightening the organizational performance contributes the citizens' happiness and the stream of times through organizations' change. To provide high quality of administrative service to citizens, trust in organizations is more important than any other capital. The improvement of organizational performance needs through this social capital. Factors about trust variables and organizational performance variables are extracted through the theoretical discussions. To do the research, public servants in 7 local administrative organizations of Gangwondo were asked to do the survey about how trust in organizations affects organizationa performances. The results explain that trust variables are related to organizational performance, and the local administrative organization which is high in trust is high in organizational performance. Trust in local administrative organizations improves the organizational performance internally and the organization will obtain trust from the citizens externally.

One of the most difficult tasks in pavement management information systems is establishing the links between performance measures of a structure and the design and construction inputs. In-situ pavement performance can be considered a response variable to many project input variables, such as design, construction, and traffic loading effects. If we are to fully understand the component of pavement performance and specify the inputs through design and construction specifications to achieve that performance we must develop quantitative relationship between input and response variables through a scientific, fully integrated Pavement Performance Analysis System (PPAS). Hence, the objective of this study is to design a database model required for developing an effective database template that will allow analysis of pavement performance measures based on design and construction information linked by location. In order to select the most appropriate database model, a conceptual database model (Entity Relationship Model) and dimensional model, which is believed to be the most effective modeling technique for data warehouse project, are designed and compared. It is believed that other state highway agencies could adopt the proposed design strategy for implementing a PPAS at the discretion of the state highway agencies.

In the initial design phase of superscalar microprocessors, a performance model is necessary. A theoretic performance model is very useful since performance for various architecture parameters can be obtained by simply computing equations, without repeating simulations, Previous studies established theoretic performance models using the relation between the instruction window size and the issue width, with the penalties due to branch mispredictions and cache misses. However, the study was intended for unlimited number of functional units, which is insufficient for the real case application. This paper proposes a superscalar microprocessor theoretical performance model which also works for the limited functional units. To enhance the accuracy of our limited functional unit model, instruction dependency rates are employed. By using trace-driven data of SPEC 2000 integer programs as input, this paper shows that the theoretically computed performance of superscalar microprocessor with limited number of functional units is quite similar to the measured performance.
