Amid the rapidly changing constructional business conditions, the volume of BTL business sectors has expanded largely during two or three years. Especially, construction works fur educational facilities of elementary, middle and high schools has been performed by the mid-sized construction companies who are not capable of doing effective and systematic quality management while the requirements of the customers are getting higher and higher. In order to have a flexible deal with the rapidly changing business conditions and also to enhance the quality level, it is the high time to reorganize the effective quality management systeme by doing the overall analysis about the quality defects in construction site. Accordingly through the investigation about the quality defects in the construction sites of domestic educational facilities, this study will focus on what kind of quality defects show. It is aimed at providing the preliminary data for the establishment of quality management fur the construction site of the domestic educational facilities by analysing the investigation results.

A dimensioning system in a manufacturing process is often complex, especially when a lot of operations are involved in the process. Determination of operational dimensions and tolerances becomes even more complicated if there exist inconsistencies between operational and design relationships among operational dimensions in machining. This chart furnishes a record of the relationships in an easy-to-grasp form, proves that sufficient stock for a cut is available even under adverse conditions, and also proves that separate operations, when taken together, will harmonize as desired. In this paper, various existing roles of the chart have been extended to an operational routing sheet by generating it automatically, providing machining conditions, and verifying operational tolerances.

According to the need for objectivity and convenience the whole planning process is devided into a secries of 8 systematic stages. But it is an unending upward spiral of incremented efforts toward improvement. So many activities should be carried out concurrently, providing a mutual supportive flow back and forth between various stages of the process depending on local conditions and requirements. The eight stages are: (1) Planning the Planning and Developing Planning Competence (2) Statements of Policy and Broad Goals (3) Data Gathering (4) Priority Statement (5) Statement of Major Alternative Proposals (6) Development of Detailed Plan (7) Implementation as a Part of the Planning Process (8) Evaluation The frame and function of the planning machinery must be adjusted to local conditions, and also flexibility is desirable, especially at the start, when adaptations are more necessary and more frequent.

This paper describes a GPSS-based, multi-server queueing model that was developed to simulate the patient flow, and to analyze the effectiveness of the patient scheduling system under various conditions. Unpredictable and unacceptably long waits to receive the service at the outpatient department of a general hospital necessitated the study. Arrival and service time distribution needed for the simulation model were generated from actual arrival and service patterns observed during the peak hours. The simulation results show that a change in patient scheduling system (i.e. time interval between appointments, starting time. and the number of physicians) from a current system would significantly reduce the patient wait time. This study provides the hospital administrator with an analysis of patient scheduling system under several conditions, and will be used to plan future scheduling system and staffing. Studies such as this can demonstrate the value of simulation in providing information for use in future planning.

Purpose: The purpose of this study is to measure the effectiveness of corporate social responsibility and service on consumers' risk perception, which ultimately influences satisfaction. Research design, data, and methodology: This study adopted experimental scenario questionnaires: 2 CSR conditions (with and without CSR) and 2 service outcomes (successful and unsuccessful). Multiple regressions were conducted to examine hypotheses. A total of 217 responses were gathered for research analysis. Results: The results of this study found that the performance risk perception and satisfaction of consumers were affected by both CSR and service. CSR was not found, however, to have a moderating effect on performance risk perception or satisfaction. Additionally, performance risk perception affected consumer satisfaction. Conclusion: The results of this study indicate that consumers respond to the conditions of company's CSR and service outcomes when they stay at hotels. Findings of this study suggest service outcomes and CSR had an effect on performance risk perception and satisfaction, although CSR did not moderate the effect of service outcomes for both performance risk perception or satisfaction. Therefore, providing satisfactory customer service and undertaking CSR activities are critical to achieving consumers' overall satisfaction.

In this study, expert system for the selection of the optimal cutting speed and feed rate was developed using NEXPERT system shell. The NC system has been usually used inefficiently because the input command, which contains cutting speed, feed-rate and the depth of cut, is fixed value which depends on principally operator's experience and machining handbooks providing a guideline for applicable ranges. On the other hand, the optimal cutting conditions vary with time, and depend on tool and machine characteristics, work materials, and cost factor and so on. In this study, if cutting factors, such as, cutting method, material type, cutting depth, and tool nose radius are specified, our expert system gets the information about the standard cutting speed form the cutting speed database, and provides optimum feed rate for these cutting conditions. This cutting speed database can be updated by inputting valid cutting speed which is obtained form the practices.

This paper proposes a method for the global optimization of redundancy over the whole task period for a kinematically redundant robot. The necessary conditions based on the calculus of variations for an integral type cost criterion result in a second-order differential equation. For a cyclic task, the periodic boundary conditions due to conservativity requirements are discussed. We refine the two-point boundary value problem to an initial value adjustment problem and suggest a numerical search method for providing the conservative global optimal solution using the gradient projection method. Since the initial joint velocity is parameterized with the number of the redundancy, we only search the parameter value in the space of as many dimensions as the number of degrees of redundancy. We show through numerical examples that multiple nonhomotopic extremal solutions and the generality of the proposed method by considering the dynamics of a robot.

The FISPACT-II inventory simulation platform is a modern computational tool with advanced and unique capabilities. It is sufficiently flexible and efficient to make it an ideal basis around which to perform extensive simulation studies to scope a variety of responses of many materials (elements) to several different neutron irradiation scenarios. This paper briefly presents the typical outputs from these scoping studies, which have been used to compile a suite of nuclear physics materials handbooks, providing a useful and vital resource for material selection and design studies. Several different global responses are extracted from these reports, allowing for comparisons between materials and between different irradiation conditions. A new graphical output format has been developed for the FISPACT-II platform to display these "global summaries"; results for different elements are shown in a periodic table layout, allowing side-by-side comparisons. Several examples of such plots are presented and discussed.

Besides recent progresses in the physics-based modelling of fission gas and helium behaviour, the scarcity of experimental data concerning their combined behaviour (i.e., cocktail) hinders further model developments. For this reason, in this work, we propose a modelling methodology aimed at providing recommendations for accelerated experimental investigations. By exploring a wide range of annealing temperatures and cocktail compositions with a physics-based modelling approach we identify the most interesting conditions to be targeted by future experiments. To corroborate the recommendations arising from the proposed methodology, we include a sensitivity analysis quantifying the impact of the model parameters on fission gas and helium release, in conditions representative of high and low burnup.
