This paper is aimed to handle quick work for all the workers and to improve the productivity by adding more effective content in Crane Monitoring System. The contributing proportion of the increase of port productivity is more increasing concerning not only the port industry, but also all the informations of container crane which is the representative equipment by the rapid increase of the volume of freight of port. The basic of rapid service is the improvement of the productivity, the information of operation as to the productivity of crane for the quick handling within yard and especially the informations of breakdown and to handle breakdown as soon as possible has a great effect on the increase of productivity.

In this paper, building information modelling (BIM) associated to the principle of significant items emerged at quantities and costs in the optimization of productivity related to the rehabilitation of the building where proposed and discussed. A quantitative and qualitative study related to the field of application based on some parameters such as pathology diagnosis, projects documents and bills of quantities were used for model development at the preliminary stage of this work. The study identified 14 quantities significant items specified to cost value based on the use of the 80/20 Pareto rule, through the integration of building information modelling (BIM) in the optimisation of labour productivity for rehabilitation of buildings. The results of this study reveal the reliability and the improvement of labour productivity using building information modelling process integrating quantities and cost significant items.

Non-parametric method such as technology efficiency, DEA/Window model and Malmquist Productivity Index (MPI) are used to measure efficiency and productivity of ICT (Information and Communication Technology) manufacturing industry and service industry over the period 2007-2011. The results of this paper indicate following: (1) Technology efficiency of the ICT manufacturing industry were found as the range of 0.34 and 0.39 over the sample period. Technology efficiency of the ICT service industry were found as the range of 0.16 and 0.20 over the sample period. (2) The geometric average of the Malmquist TFP indexes on ICT manufacturing industry indicated the productivity improvement an average of 8.3 percent. The geometric average of the Malmquist TFP indexes on ICT service industry indicated the productivity improvement an average of 1.6 percent. (3) TIER analysis result on ICT manufacturing industry showed that optimal bench marking made by storage devices${\rightarrow}$wireless communication equipment${\rightarrow}$broadcasting equipment${\rightarrow}$radio, recording and playback devices${\rightarrow}$computers, printers, video and audio-visual equipment path. TIER analysis result on ICT service industry indicated that optimal bench marking made by computers and packaged software${\rightarrow}$wired communication${\rightarrow}$communication, information, detection equipment${\rightarrow}$consulting and construction for computer systems integration${\rightarrow}$industrial machinery and equipment rental${\rightarrow}$telecommunications reseller${\rightarrow}$system software development and delivery${\rightarrow}$hosting path.

The productivity of container terminal is usually regarded same as the productivity of quay crane. Operation of quay crane for the export is started from picking up a container in yard block. In doing so, smooth flow of container is vital to maximize the productivity of quay crane. Improvement of quay crane's productivity means improvement of entire productivity in container terminal, which reinforces the competitiveness of terminal consequently. Setting effective plan is essential to improve work flow from yard to quay crane. For optimal plan, it is necessary to gather information about exact time schedule of come-and-go containers for loading, amount of containers that will be come to terminal. Generally, the arrival time of containers and the amount of containers are definite and predictable. However, in the case of export container, the arrival time of containers is random and unpredictable. This study examines the pattern of coming-in containers as time goes in container yard and provides the solution to how to plan export yard considering the change of state in terminal and adapt it to container yard plan

This study analyzed the effect of small manufacturing firms' systematic documentation on productivity. The study results showed that establishment of work system documentation significanlty affectd defect decrease(p<.05) and production efficiency(p<.01), but ducumentation experience didn't significantly affected productivity improvement. So, it is suggested that firms should establish documentated work system and conduct education & training rather than depending on experiential aspect to improve productivity. This study provided implications for checking importance of documentation factor on productivity improvement and verifying the effect of documentation in quality management aspect.

The object of this paper is to Study the work measurement which is one of the principal technique in work study for the improvement of Productivity in the foundry industry. Most of domestic mechanical enterprise using the expensive foreign machinerise is inoufficient for the standardization of the operation method and time. Therefore, the improvement of operation and productivity through the introduction of the work measurement is an urgent task. Therefore, this paper is contribute to the improvement of operation and to reduce the loss time through the application of the work measurement based on the case study conducted at W-Foundry Corporation. The summary of this study is follows; 1. The measurement of operation efficiency can be accomplished by the standard time. 2. The detailed causes and counter-proposal of loss time can be established, 3. More than 50% of loss time is attributed to c/p.

This paper deals with a case study of layout design and improvement in medium and small-sized manufacturing factories. The shop layout affects greatly the productivity of manufacturing systems and we introduce some cases in which shop layouts are changed to improve the productivity step by step. Based on case studies, we propose also some guides to improve and design the shop layout in medium and small-sized manufacturing factories.

According to the liberalization of the air transport industry, the operation of airport also takes account of economic efficiency. The owners or the operators of an airport or airport systems want to know what is the best way to achieve the best performance in the aspect of economic efficiency and they are willing to improve the airport operation system. Prerequisite for the improvement of economic efficiency is to measure the performance of not only their own airports but the other airports. This study presents the result of performance measurement of Korean airports. The overall costs performance, labor productivity, capital productivity, revenue performance and profit performance are estimated and interpreted. As conclusions, the suggestion about airport system improvement is presented.
