The purpose of this study is to suggest a systematic procedural model for selecting competent project promoter. The proposed model was made by comparing domestic regulations and procedures with foreign nations', and through interviews with experts and literatures survey. The summaries of this paper are as follows. The current promoter selection procedure was evaluated by reviewing relevant papers, regulations and existing model. Some obstructions which hinder PPI project activation were identified, those are inadequacy of promoter qualification and negotiation process, lack of communication between parties, etc. Some alternatives which remove major obstructions are embodied in the model. The suggested model is comprised of PQ(prequalification), two phased evaluation for the technical proposals which include alternate, communication meeting, etc. To manage the overall procedure well, an involvement of professional "project promoter selection team" would be highly recommended. They will participate in each evaluation stage with full activities, and provide government with some technical materials for selecting promoter as coordinator.

This study is to prepare the emergency response procedures for an unmanned LRT (Light Rapid Transit) which is being commercially operated recently. This emergency response procedure adds several particular characteristics which happens in the hardware and software aspects at the unmanned LRT in addition to the present emergency response procedures. The emergency response procedure has to conform to the emergency response planning. For doing that this emergency response procedure includes three important sub systems. First of all, the functional emergency response system has been developed. Secondly, Standard Operation Procedure (SOP) is suggested for the better and faster emergency response between emergency response personnel and institutes. Thirdly, emergency response training and drilling system is also provided for emergency response personnel. Finally, a software program for emergency response training and drilling will be developed and suggested to be used for the emergency response personnel.

The objective of this study is the development of size, shape and topology discrete optimum design algorithm which is based on the genetic algorithm. The algorithm can perform both shape and topology optimum designs of trusses. The developed algorithm was implemented in a computer program. For the optimum design, the objective function is the weight of trusses and the constraints are stress and displacement. The basic search method for the optimum design is the genetic algorithm. The algorithm is known to be very efficient for the discrete optimization. The genetic algorithm consists of genetic process and evolutionary process. The genetic process selects the next design points based on the survivability of the design points selected form the genetic process. The evolutionary process evaluates the survivability of the design points. The evolutionary process evaluates the survivability of the design points selected form the genetic process. The efficiency and validity of the developed size, shape and topology discrete optimum design algorithm was verified by applying the algorithm to optimum design examples.

Arbitration is adopted recently as dispute resolution vehicle for major construction projects in Korea. These arbitration cases show that complex construction disputes are resolved reasonably by newly-introduced arbitration process and this trend will continue. This paper reviews the expanded concept of dispute resolution for the new approaches to the disputes resolution processes in construction projects. The expanded concept includes that disputes need to be assessed reactively and proactively in construction project and need to be managed effectively in advance. In this paper, dispute resolution methods used in Korea are reviewed and analyzed against ADR methods available in US construction industry The new approaches to the dispute resolution Processes are based on the concept of 'Disputability' which means dispute management through prevention, avoidance and predictability of dispute issues and characteristics.

The process of design management by public client has not performed effectively due to lack of the formal guidelines and procedures in domestic public projects. The purpose of this research is to develop the guidelines and procedures of design management for public clients. The research methodology is to analyze current status of design management process in domestic and overseas cases and to develop the guidelines based on the administrative stages of design process along the project. The guidelines of design management developed by the design stages of pre-contract, contract, and post-contract stages to classify administrative procedures. The outcome of this research is able to be utilized by the public clients and design firms to standardize the process of design management and minimize potential risk during the process of the project.

The purpose of this study is to investigate the relationship between the distance function average speed and the speed function. Particularly, in this study, we investigate the process of constructing the speed function in the distance function (irrational function, exponential function) which is difficult to weaken the argument in the denominator. In this process, students showed various anxieties and expressions about the procedural knowledge that they constructed first. In particular, if student B can not explain all the knowledge he already knows in this process, he showed his reflection on the process of calculating the differential coefficient. This study adds an understanding of the calculation method of students in differential coefficient learning. In addition, it is meaningful that the students who construct procedural knowledge at the time of calculating the differential coefficient have thought about how to provide opportunities to reflect on the procedure they constructed.

Recently the need for network surveillance to detect abnormal behavior within dynamic social networks has increased. We consider a dynamic version of the degree corrected stochastic block model (DCSBM) to simulate dynamic social networks and to monitor for a significant structural change in these networks. To apply a control charting procedure to network surveillance, in-control model parameters must be estimated from the Phase I data, that is from historical data. In network surveillance, however, there are many situations where sufficient relevant historical data are unavailable. In this paper we propose a self-starting Shewhart control charting procedure for detecting change in the dynamic networks. This procedure can be a very useful option when we have only a few initial samples for parameter estimation. Simulation results show that the proposed procedure has good in-control performance even when the number of initial samples is very small.

This paper presents a risk assessment methodology for standard flight procedures using recorded automatic dependent surveillance-broadcast (ADS-B) data. Utilizing the proposed methodology, the results of risk analyses in RKSI (incheon international airport) and RKSS (gimpo international airport) using trajectories that are regenerated based on 100 days of ADS-B data are presented. For the risk metric, detect and avoid well clear (DWC) is used. With this index, each procedure was evaluated for the sections with highest level of risk. Among the standard instrument departure (SID) of RKSI, the section between SI712 and RANOS of RNAV BOPTA 1L showed the highest level of risk. For the standard terminal arrival route (STAR) of RKSI, section between SI947 and DANAN of RNAV GUKDO 1N wasthe one with the highest level of risk. For RKSS, the segment between SS726 and SS727 of RNAV BULTI 1X and the segment between KAKSO and KALMA of RNAV OLMEN 1D showed the highest level of risk among the SIDs and STARs, respectivly.
