Because a procedure is complicated and various related parties participate in the redevelopment and reconstruction project, it can be extended to diverse disputes when the relation with the related parties is smoothly adjusted. In particular, when the dispute occurs in a phase of occupancy after the complete construction, the regional residents-centric association must give up many rights of invisible parts caused by the construction company's profit maximization because they are short of professionalism about the business. Accordingly, this study is aimed at providing the construction project manager's dispute and claim process for responding to the dispute or claim reasonably and for obtaining the client's (association) rights for the reconstruction project, and at developing the checklist for obtaining the necessary documents by each phase, when the dispute or claim is made by the association against the construction company after the completion of construction. Through this study, the association can obtain the related documents in advance and can implement the reasonable response data when the dispute or claim occurs due to it. Also, it will enable the construction manager to analyze the project costs reasonably and will reduce the estimated wastes. That is, the work efficiency is expected to be improved.

Volunteer computing is a new computing paradigm that performs operations on idle resources of many nodes. The operation method of the client application for the execution of the volunteer computing is determined by the setting information of the user. Ideal operation requires optimized settings for system features and operating methods of other applications. In this paper, we analyze the usage ratio of CPU and GPU periodically, and develop a manager that dynamically applies optimized options. Through our proposed mechanism, the performance of the task computing is higher than that of the existing Volunteer Computing, and the performance interference is minimized. It is expected that volunteers will be able to provide higher computing resources for Volunteer Computing Project.

Although more than 90% of the yearly freight has been made through shipping the positioning system for the ships and cargos to support effective transportation of the freights has not been established yet. The government has been working on developing such a positioning system in many perspectives. The main problem in building a such system is that individual shipping companies are running different types of system and databases. This would cause duplicated investment with wasting money and time and this becomes an obstacle to the easier information sharing. Therefore, this study has mainly demonstrated developing a manager's system in the positioning system for the ships and cargos based on client-server scheme using electronic nautical charts on which the international standards are already available. In addition, this study also proposed an independent system which can be used in the ports with different locations thereby preventing duplicated investments.

The web has been evolving as an indispensable part of our lives since Berners Lee introduced the first web sever and browser in 1990. From the web end user's point of view, the response time is a matter of concern. Moreover the throughput is an important factor to consider for the system manager's point as well. It's not easy to estimate the performance of a web application because it depends on various elements comprising the whole operational environment of the Internet from networking, client and server computing powers, DBMS and OS capabilities, to application itself. This paper suggests a coarse grained simulation model for web application performance estimation based on the data measured by Buch and Pentkowski [1] and the analytical model proposed by Gunther [2]. The result of the simulation model almost coincides with the measured data and estimates the performance of a new environment.

The construction industry has the most safety accidents among domestic industries. Special care must be taken because disasters in the construction industry lead to social problems caused by huge property losses and casualties. As a result of this, there is a growing awareness of disasters occurring in the construction industry, and government departments are tightening regulations on safety management. In particular, the OSHA (Occupational Safety and Health Agency) focuses on the expansion of protection targets and the clarification of responsibility in the full amendment OSHA. As a result, a study that focuses on safety management by client's responsibility is needed. In this study, the project performance capability assessment of construction project management contractors, which is being carried out with uniform assessment criteria without considering the characteristics of the construction project, is considered and all the amendments to the OSHA are considered, and the factors were derived for improvement measures.

Intelligent pipeline inspection gauges (PIGs) are inspection vehicles that move along within a (gas or oil) pipeline and acquire signals (also called sensor data) from their surrounding rings of sensors. By analyzing the signals captured in intelligent PIGs, we can detect pipeline defects, such as holes and curvatures and other potential causes of gas explosions. There are two major data access patterns apparent when an analyzer accesses the pipeline signal data. The first is a sequential pattern where an analyst reads the sensor data one time only in a sequential fashion. The second is the repetitive pattern where an analyzer repeatedly reads the signal data within a fixed range; this is the dominant pattern in analyzing the signal data. The existing PIG software reads signal data directly from the server at every user#s request, requiring network transfer and disk access cost. It works well only for the sequential pattern, but not for the more dominant repetitive pattern. This problem becomes very serious in a client/server environment where several analysts analyze the signal data concurrently. To tackle this problem, we devise a fast in-memory cache manager, called T-Cache, by considering pipeline sensor data as multiple time-series data and by efficiently caching the time-series data at T-Cache. To the best of the authors# knowledge, this is the first research on caching pipeline signals on the client-side. We propose a new concept of the signal cache line as a caching unit, which is a set of time-series signal data for a fixed distance. We also provide the various data structures including smart cursors and algorithms used in T-Cache. Experimental results show that T-Cache performs much better for the repetitive pattern in terms of disk I/Os and the elapsed time. Even with the sequential pattern, T-Cache shows almost the same performance as a system that does not use any caching, indicating the caching overhead in T-Cache is negligible.
