  • Achieving sustainability targets on construction projects has increasingly become one of the prime strategies for construction organizations. To provide more detailed guidance on sustainability implementation on projects, Construction Industry Institute (CII) Research Team (RT) 304 developed a catalog of the Construction Phase Sustainability Actions (CPSAs). The primary objective of this paper was the development of two support tools, the CPSA Screening Tool and the CPSA Implementation Index, that could be used to enable efficient application of CPSAs, support sustainability-related decisions, and measure CPSA implementation and performance. The authors developed the tools in four stages: conceptual, detailed planning, tool programming, and testing. The tools were then demonstrated on a capital project to confirm their efficacy and applicability. This paper presents the background, inputs and outputs, and the algorithms of each tool. The CPSA Screening Tool can prioritize the CPSAs most relevant to a project; the CPSA Implementation Index enables continuous monitoring of implementation levels.

  • Although waste management in construction industry has a significant impact on both economical and environmental issues, the current level of waste management performance in Korean construction is reported as relatively low. To improve any type of management performance, it is necessary to diagnose the current status of the performance level. In this context, this research is aimed to identify important factors in influencing the waste management performance and to develop an evaluation tool for the purpose of assessing the level of the performance for a particular construction site. In this paper, 59 influential factors have been identified and categorized into five classes, i.e., manpower, material, method, management, and policy, in terms of the characteristics of the factors. In addition, an evaluation tool has been developed in order to effectively quantify all the 59 factors based on a thorough industry survey. The output of the Tool, which is Waste Management Index, effectively assess the level of waste management performance for a particular project and provide with the most leveraged factors in need for improvement in waste management performance.

  • To manage a cluster of distributed server systems, a number of management aspects should be considered in terms of configuration management, fault management, performance management, and user management. System performance monitoring and reporting take an important role for performance and fault management. In this paper, we present distributed system architecture modeling of a performance monitoring and reporting tool. Modeling architecture of four subsystems are introduced: node agent, data collection, performance management & report, and DB schema. The performance-related information collected from distributed servers are categorized into performance counters, event data for system status changes, service quality, and system configuration data. In order to analyze those performance information, we use a number of ways to evaluate data corelation. By using some results from a real site of a company and from simulation of artificial workload, we show the example of performance collection and analysis. Since our report tool detects system fault or node component failure and analyzes performances through resource usage and service quality, we are able to provide information for server load balancing, in short term view, and the cause of system faults and decision for system scale-out and scale-up, in long term view.

  • Background: This study aimed to determine and define the elements of an Fatigue Risk Management System (FRMS) diagnostic tool to assist an organization in systematically assessing its level of implementation of an FRMS. Methods: A modified Delphi process was used involving 16 participants with expertise in sleep science, chronobiology, and fatigue risk management within occupational settings. The study was undertaken in two stages 1) review of elements and definitions; 2) review of statements for each element. Each stage involved an iterative process, and a consensus rule of ≥ 60% was applied to arrive at a final list of elements, definitions, and statements. Results: Stage 1: a review of elements (n = 12) and definitions resulted in a final list of 14 elements and definitions with a consensus of ≥ 60% achieved after 2 Delphi rounds. Stage 2: a review of statements (n = 131) resulted in a final list of 119 statements with a consensus of ≥ 60% achieved after 2 Delphi rounds. Conclusion: The final FRMS diagnostic tool will enable an organization to systematically assess the level of implementation of their current FRMS and identify gaps and opportunities to reduce risk.

  • This study examined the hygiene management of ultrasound probes by examining the cleaning tools for hygiene management of ultrasound probes, the presence or absence of wearing glove as a personal protective equipment, and the awareness of ultrasound probe hygiene. Parts 154 questionnaire about people working in the ultrasound room were surveyed and analyzed. The single gel removal tool of the ultrasound probe was most frequently used with a 48.7% cotton towel, and for double gel removal tools, the first gel removal tool was 42.4% cotton towel and the second gel removal tool was used with 57.6% wet tissue. Antimicrobial wipes were the most commonly used drug and instrument used in ultrasound hygiene management at 58.4%. According to the survey of the presence or absence of wearing glove during ultrasound examination, 46.8% were found to be unworn. When examining the intracavity ultrasound, 30.9% of those who do not wear glove and 61.0% of hygiene awareness of ultrasound probes are 'normal'. According to age, ultrasound probe gel removal tool was not significant difference(p>0.05). According to the working organization and the working department, it was significant difference to wearing gloves during ultrasound examination(p<0.05). Therefore, in order to properly sanitize the ultrasound probe, it is considered that a guideline for hygiene management of the ultrasound probe that fits the situation in Korea is necessary, and it is considered that thorough hygiene management training for inspector is necessary for efficient hygiene management of the ultrasound probe.

  • An efficient measurement and evaluation system for hand tool tasks will provide a practical solution to the problem of designing and evaluating manual tool tasks in the workplace. Few studies on the biomechanical analysis of hand postures and tool handling tasks exist because of the lack of appropriate measurement techniques for hand force. A measurement system for the finger forces and joint angles for analysis of manual tool handling tasks was developed in this study. The measurement system consists of a force sensing glove made from twelve Force Sensitive Resistors and an angle-measuring glove (Cyberglove$\^$TM/, Virtual technologies) with eighteen joint angle sensors. A biomechanical model of the hand using the data from the measurement system was also developed. Systems of computerized procedures were implemented integrating the hand posture measurement system, biomechanical analysis system, and the task analysis system for manual tool handling tasks. The measurement system was useful in providing the hand force data needed for an existing task analysis system used in CTD risk evaluation. It is expected that the hand posture measurement developed in this study will provide an, efficient and cost-effective solution to task analysis of manual tool handling tasks. These tasks are becoming increasingly important areas of occupational health and safety of the country.
