This research investigates the possibility of using the postural sway of patients as a reference for measruing the progress of the disease and healing of patients who received total hip replacement; the progress of the disease by X-ray pictures, the pain felt by the patients, and the difficulties encountered in moving the joints. The measurements on the force platform were taken during a 25 second period standing on both feet and during a 5 second period standing on one foot with both eyes open. The result of the research showed that the trace and area of the overall length of postural sway was a good indicator which represented the healing progress of the patients who received total hip replacement, and the weakening of the muscles and the recovery process for 3 or 4 month after receiving the operation, which did not appear on X-ray pictures, were exhibited on the postural sway. Finally, standing on a single foot represented the healing progress much better than standing on both feet.

Multi Progress Planning System problem in a multi-stage manufacturing system have a complexity and peculiarity different from other kinds of production system. World leading company has invested much cost and effort into a Real-Time Planning System and intelligent manufacturing field to obtain their own competitiveness. Especially Real-Time Planning System for ship production process as a part of intelligence for a shipyard. Real-Time Planning System, simulation based system, or virtual manufacturing system is an approach to achieve a such goal. It is expected that the Real-Time Planning System will contribute to the improvement of the productivity in working process at a shipyard. Also, This Real-Time Planning System will optimize the entire shipbuilding process in a multi progress planning environment for the delivery.

We fabricated resistive superconducting fault current limiters based on $YBa_{2}Cu_{3}O_{7}$ thin films and investigated position dependence of quench progress. The $YBa_{2}Cu_{3}O_{7}$ film was coated insitu with a gold layer and patterned into 1 mm wide meander lines by photolithography. The limiters were tested with simulated fault currents. Quench progress depended significantly on the position in the limiter with respect to electrodes. The limiters quenched fastest at the part farthest from the electrodes. the limiters quenched fastest at the part farthest from the electrodes and slowest next to the electrodes. This phenomenon was more prominent near the minimum quench current. At high fault current the quench started simultaneously on all parts of the limiters and the subsequent progress of quench depended only weakly on the position. The heat transfer from limiter meander lines to electrodes explains these results.

Insulation diagnosis techniques of power equipments for the stable power supply and prevention from accidents are of high importance. Diagnosis techniques is able to prevent from large accidents before they happen by finding signs of the accidents. From this point of view, this paper simulated discharge progress and partial discharge using needle-plan electrode system in air, studied the distribution of frequency spectrum of the radiated electromagnetic waves using biconical antenna and spectrum analyzer. From results of this study, the new method was introduced for measurement and analyzation of the radiated electromagnetic waves in accordance with discharge progress in air, Besides, according to the consideration of the mutual relation between frequency spectrum of the radiated electromagnetic waves and discharge progress, it was confirmed that detecting partial discharge and estimating discharge progress were possible.

One way of evaluating the effectiveness of a dairy breeding program is to measure response to selection. This may be direct or indirect. The objectives of this study were to estimate expected progress for direct selection on milk, fat and protein yields; to estimate the expected correlated responses on indirect selection for milk, fat and protein yields in Zimbabwean Holstein cattle and to establish the effect of selection intensity on responses. The Animal Model contained fixed effects of herd, year of calving, calving month, dry period, milking frequency and additive effects pertaining to cows, sires and dams. AIREML software package was used to analyse the data. The genetic and phenotypic parameters obtained in this study were used to compute direct and correlated responses to selection. Because of the higher heritabilities in first parity, genetic progress was found to be greater when selection was practised on first parity cows as compared to later lactations. It is therefore recommended that older cows in the herd be replaced with improved heifers so as to enhance genetic progress.

Construction projects have shown a dramatic increase in size and complexity during the recent years that precise management has been recognized as one of key factors leading the project to success. It has been investigated that management in construction sites is generally done based on the experience of site engineers. Such experience based decision making lacks reliability that could bring disastrous results such as delay and cost overruns. The purpose of this study is to suggest a process progress pattern analysis method that is expected to be used as an objective reference for site managers to aid the decision making done regarding process progress management.

As the importance of maintenance of reinforced concrete structure recently has emerged, the attention of durability of structure has been increasing. There are many studies about durability decline especially due to the carbonation. In order to study carbonation progress after surface repair of carbonated concrete, each carbonation penetration velocity from different repair materials of concrete structure is compared through the experiment of carbonation accelerating CO2 concentration to 100%. As carbonation infiltration progress is predicted through this study, the counterplan of service life evaluation will be prepared on selection of repair materials of concrete structure.

Construction projects are managed by focusing on the results of projects. Moreover, cost and schedule are managed separately even though the efficiency of integrated management is very high. This paper proposes existing and progress control research of existing quantity the integrated information uses WBS-CBS. Schedule and cost are most important in construction projects. Specially, progress and cost are relationship of the managing integrated in many construction management. The quantity of materials for the works of construction is the base to create activities and a network. The quantity of materials of materials for the elemens of a building is a base of cost estimation and resource. allocation. This study suggest method for relating the schedule and cost information through the case study of construction field engineers.

There are many studies about durability decline especially due to the carbonation. In order to study carbonation progress after surface repair of carbonated concrete, each carbonation penetration velocity from different repair materials of concrete structure is compared through the experiment of carbonation accelerating CO₂ concentration to 5%. As carbonation infiltration progress is predicted through this study, the counterplan of service life evaluation will be prepared on selection of repair materials of concrete structure.

The type and proportion of construction work varies depending on the stage of progress, and the frequency of inspection and defect occurrences are different. If it is determined to be defective after the inspection, a delay may occur, and additional manpower and resources are required. Therefore, it is necessary to prevent these risks by classifying, deriving, and managing key management woks according to the progress. This study aims to contribute to the efficiency of the supervisor's inspection work by identifying the types of construction that should be managed intensively for each construction progress and deriving the time when defects occur frequently in each construction type.
