In order to calculate the quality management cost of construction work, the process must conform to relevant laws and regulations. In details, the cost of the various items such as quality test fee and quality control activity cost are required to be calculated. Regarding the quality management costs, the labor cost is applied to the quality examination fee and the calculation unit quantity in the construction quality management duties. The application of the unit price of the labor cost stipulates that Construction Association of Korea and Korea Engineering & Consulting Association apply the unit price which is surveyed and published. However, in the related laws and regulations, the standard of the quality manager and quality tester is not clear. This accounts for the confusion in the cost of construction management and the cost of labor. In the current law, the allocation standard of quality control personnel is specified according to the size of the construction, but the standard of placement of quality testers is not specified. At the construction site, there is no assignment criteria manpower for quality testers except quality managers, or very little work is being done. The quality control personnel conducts the quality test work to be carried out by the quality tester, and this carrying out heavy work. Therefore, it is difficult to maintain quality control activities. In this study, the labor cost of quality management expenses and the allocation criteria of quality managers and quality testers are established and presented for the purpose of securing the quality of the construction work and preventing the construction work. It is stipulated that the standards of the relevant laws and regulations, which are not clear, should be classified into quality control personnel and quality testers according to the size of the construction. Based on the unit price of Korea Engineering & Consulting Association, the personnel expenses of quality managers and quality testers are proposed to apply the unit price of engineer (professional engineer, specialist, advanced, intermediate, beginner) and skilled technicians (advanced, intermediate, beginner).

Many leading companies know that the best quality dominates the world economy in the next 21 century and Six Sigma Program of Motorola Corporation could be considered as a typical model for it. Six Sigma Program is based on the quantitative analysis and the professional qualify manager's training. In fact, this program is a strategy to accomplish the total quality innovation by applying the standardized quality control techniques to the manufacturing or non-manufacturing operation parts. Since many companies recognized their successes and vision, leading domestic companies are very much interested in establishing and driving this program. However, they must understand the meaning of the program correctly and prepare the practicing strategy sufficiently, since there are many differences in ways to drive between other quality program such as TQM and Six Sigma Program. Otherwise, it should lead a big disappointment and another vapour of management paradigm. This study considers the concepts and features of Six Sigma Program of Motorola Corporation and suggest the effective practicing strategy, pointing out the possible problems.

Traditional quality control for manufacturing or service sector is not suitable for the quality control of a project as the project is one-time task constrained by time, cost, and quality. To meet the internal and external customers' requirements, quality costs approach to the project will be effective. Hence, we propose PONC (price of nonconformance) estimation procedure and a mathematical model, which are focused on activity-based prevention in the execution step and warranty step of EPLC (extended project life cycle). This procedure and model will help project manager develop preventive action plan for project quality costs minimization from nonconformance risk activities and PONC estimates information.

This paper suggests a new process structuring method, which we call process modularization, for decomposing and grouping activities in a process. Above all, we propose the concept of a module that is a group of activities positioned on the same flow before and after control constructs. Since activities in a module are relatively strongly interrelated with one another, it is important to take into consideration of these together. A design structure matrix (DSM) is used to structure the process because it has a lot of advantages in process modeling and analysis. We developed two algorithms: the restricted topological sorting (RTS) algorithm for ordering activities and the module finding (MF) algorithm for detecting modules in a process, which utilize the DSM. The suggested approach enables a firm's manager to design and analyze the process effectively. We also developed a supporting tool to accelerate the progress of process modularization. The supporting tool aids the process manager in finding the module and understanding the process structure easily. An illustrative example is addressed to show operations of the suggested approach.

Our study focuses on the implementation of IS development methodology as the innovation of IS organization. We have two main research objectives. We Intend to understand the critical factors affecting the implementation process of IS methodology. We also intend to deeply analyze the relationship among the implementation processes of methodology. The whole innovation process is divided into detailed four levels tilth dynamic and evolving Point of clew a cognition level, an adoption level, an acceptance level and an usage level. The results of our study are as follows. The main factors affecting initiation level of the IS methodology are the innovativeness of IS members, the existence of champion manager, training, the existence of IS performance gap, executive supports for IS organization, and the relative advantage of IS development methodology At the Implementation level, It is understood that the existence of champion manager executive supports, training and the relative advantage of innovation are the main factors. However, the complexity of Innovation is a megative factor about the quality of accepting and using the methodology In Innovation process. In performing the Innovation process, the Previous level gives very notable affection to the continuous next level. However it's also understood that positive attitude of adoption level does not directly affect the quality of using Innovation. Therefore, IS managers must pay attention to manacle each level of the Innovation Process to successfully accomplish the Implementation of IS methodology.

In this paper presents the method of the Optimal Mobile Router Designation (OMRD) using QM(Quality of service Manager) in the nested mobile network. QM is positioned on TLMR (Top Level Mobile Router) in the nested mobile network and manages the information of all MRs in the mobile network. When MN (Mobile Node) moves to a new MR, OMRD (Optimal Mobile Router Designation) selects the candidate MRs group and decides an optimal MR considering the mobile characteristics. OMRD reduces maximally the production of handover and removes the transmission delay of a new call and a handover call resulted from the wireless insufficient resource. Also, it prevents the concentration in a specific MR and maintains equally the load of the whole network.

Project manager plays a very important role in the success of any project. The primary duty of the project manager is to combine the outcomes or results of the various processes and activities of project management into a systematic project management strategy or plan for the project. In the construction industry, a lack of motivation is an urgent problem for many project managers in construction and engineering projects. Lack of motivation affects the quality and productivity of jobs, reducing profits and growth for companies, businesses, contractors or organizations that rely on human resources. The reasons for this lack of motivation are diverse ranging from salary to culture to life and working environment, among others. Through surveys and data analysis using Cronbach's Alpha reliability and EFA (Exploratory Factor Analysis), our research scaled the factors affecting work motivation of project managers in the construction industry in Vietnam. The research results identified six major groups of relevant factors including (i) salary and benefits, (ii) work environment, (iii) promotion opportunities, (iv) organizational culture, (v) interest in the job, and (vi) relationship with the organization. From there, this paper contributed useful information as well as measures for businesses, companies, contractors or organizations in the construction industry.
