Accuracy Improvement of Real-Time Location Tracking for Construction Workers

Extensive research has been conducted on the real-time locating system (RTLS) for tracking construction components, including workers, equipment, and materials, in order to improve construction performance (e.g., productivity improvement or accident prevention). In order to prevent safety accidents and make more sustainable construction job sites, the higher accuracy of RTLS is required. To improve the accuracy of RTLS in construction projects, this paper presents a RTLS using radio frequency identification (RFID). For this goal, this paper develops a location tracking error mitigation algorithm and presents the concept of using assistant tags. The applicability and effectiveness of the developed RTLS are tested under eight different construction environments and the test results confirm the system’s strong potential for improving the accuracy of real-time location tracking in construction projects, thus enhancing construction performance.

The Spillover Effects on Employees’ Life of Construction Enterprises’ Safety Climate

Organizational safety climate will produce spillover effects and thus affect the individuals’ performance in their family life. As a mainstay industry in many countries, the construction industry has a considerable number of employees and the research on the spillover effects from the safety climate of construction enterprises has important theoretical and practical significance to improve the safety behavior of construction employees in their family life. In this study, we thoroughly reviewed the literature to identify the dimensions of the safety climate spillover, obtain empirical data of the construction employees through a questionnaire survey, and use the data analysis method to study the spillover effects of the safety climate of the construction enterprises from the perspective of work–family integration, and reveal its influence mechanism. This study developed a questionnaire to measure the safety climate spillover of the construction enterprises including two dimensions, namely values and behaviors, with nine measured items. Management commitment and safety attitude in the safety climate were positively related to the spillover, and management commitment had the greatest impact on the spillover, while the other components were not significantly related to the spillover. The two forms of spillover, values and behaviors, were mutually influential, and the safety climate had a more significant impact on the values. This paper contributes to the current safety research by developing a factor structure of spillover effects of the safety climate on the lives of construction employees, thus providing a more profound interpretation of this crucial construct in the safety research domain. The spillover effects of the safety climate’s measurement questionnaire serve as an important tool for spillover among construction enterprises. Findings can facilitate improvement in both theories and practices related to the spillover effects of the safety climate on the lives of employees. This paper studies the spillover effects of construction enterprises’ safety climate, to reveal its influencing mechanism, and can thus provide theoretical guidance for preventing safety accidents in employees’ life.

ER-CLT: A Secure Emotion Recognition-Based Child Location Tracking System

As social recognition with respect to safety has recently improved, actions to prevent safety accidents and prepare appropriate measures for them have been actively taken. In particular, children are exposed to crimes such as kidnapping and abduction. To prevent child accidents, studies on smart device-based location tracking technologies have been conducted continuously. However, the global positioning system (GPS) technology used for location tracking cannot detect the location of the target accurately and has security vulnerabilities such as exposure of location information. To solve these problems, we propose an emotion recognition-based child location tracking (ER-CLT) system. The proposed ER-CLT system receives the child's audio data and determines whether the child is in an emergency situation by extracting emotional information from the audio data. The ER-CLT system improves the accuracy of location tracking compared to existing studies and provides secure location tracking functions by using encryption, authentication, integrity, and privacy protection.

하둡 기반의 통합설비 모니터링시스템 설계 및 구현 사례 연구

SCADA and DCS that have performed automatic control and monitoring activities increase the productivity of enterprise in industries. In such systems, although their performance had been improved, there are still many deficiencies in predictive maintenance which can foresee the risk of any kinds of accidents. Because the data acquisition systems of main facilities are being distributed throughout the whole plant and therefore, integration of data obtained from the systems is very difficult. Accordingly, techniques that acquire meaningful information from the gathered data through realtime analysis still need to be improved. This paper introduces a developed facility monitoring system which can predict equipment failure and diagnose facility status through big data analysis to improve equipment efficiency and prevent safety accidents.

For the matter of elevator, one of the multi-use facilities for unspecified public, the JIS has re-established and reformed to apply to the environment in South Korea for the past 20 years. In the aspect of safety assurance, it was inevitable to suggest improved measures. The government, Ministry of Public Administration and Security has secured the safety by enhancing the safety management functions in the elevator inspection standards and expanding its safety device measures. Further, the international inspection standard has been introduced, which is about unifying inspection standard system into the international standard code. In March 14th 2012, the international standard (EN) has been amended and fully announced. Escalator and passenger conveyor among lift devices have several common danger factor that cause safety accident. First, the accident caused by decreased braking power of brake. Second, the accident caused by the rate difference between handrail and tread-board. Third, the accident caused by defects of contraflow preventing device or carelessness inspection. Fourth, the accident caused by wet tread-board or wet floor of platform which makes passenger slip and fall. As the improvements to prevent and reduce these negligent accidents, the inspection list to check and methods should be subdivided and applied for each accident likelihood cause for safety management enhancement and safety assurance of existing escalator and passenger conveyors. The escalators and passenger conveyors without safety devices in existence should be obliged to modify the part of the system or install additional safety device. With making these measures obligations, it requires to improve the system to be suitable for the international inspection standard and to have measures to prevent safety accidents. It also needs to arrange improvements for skid accident of tread-board by the external environment factors such as snow and rain.

Evaluating Construction Workers’ Understanding of Safety Signs

It has been suggested that many construction workers are never properly educated on the meaning of safety signs. In particular, considering that any safety accident can lead directly to a serious disaster, understanding safety signs is a critical part of safety management. Therefore, the purpose of this study is to analyze construction workers’ awareness of and understanding of safety signs. The research found that most construction workers perceived that safety signs play an important role in preventing safety accidents. However, almost half of construction workers did not understand what construction safety signs convey, which indicates an urgent need for education on safety signs at construction sites.

국내외 실태조사 분석을 통한 연안역 안전시설의 개선방향

Recently, the risk of safety accidents in the coastal zone has been increased due to revitalization of marine leisure and tourism. Because of a lack of regulations about technical and maintenance aspect for safety facilities, the effective measures to prevent safety accidents in the coastal zone have not taken with increasing rate of the accidents. The nature of land/sea and behavioral characteristics of a fisherman/port laborer/tourist/people at leisure should be taken into account properly when safety facilities to prevent safety accidents in the coastal zone are installed, since the characteristics of land/sea and many activities such as fishery, harbor works, tour, leisure are mixed in the geographic and environmental condition of the coastal zone. This study analyzes the current problems on the safety facility in the domestic coastal zone through the domestic and foreign(Hongkong, Macau) field survey. Also the direction of the improvement about the safety facility are proposed.

Quantitative business decision-making for the investment of preventing safety accidents in chemical plants

This paper proposes a new quantitative method of supporting business decision-making while investing safety related facility and service. This method suggests the priority of investment relevant to safety within limited budget, so most possible hazards can be removed or the company may not invest money for the acceptable hazards depending on the bud. The typical theory that risk is equivalent to the multiplication of frequency and severity, given by CCPS (Center for Chemical Process Safety) in American Institute of Chemical Engineers (AIChE), is modified to consider more detailed classifications. The criteria of decision are determined by the manager's survey. Computation of R matrix results the priority of investment and the investment is finally chosen by the decision criteria. This method is proved to be effective in reducing safety accidents by proper management through the analysis of real accident data of a Korean petrochemical company for using Yonsei Safety Information Management System (ySIMS). We collected 5500 accident data for one and a half year by using the ‘detailed classification sheets’ including more than 60 accident cause types. As a result of applying this system to the company, the number of accidents of class A and B was significantly reduced in 6 months after the systematically chosen investment by 70% and 62% that was from 33 to 10 and from 122 to 47, respectively. The aim of this study is to manage safety accidents properly and to prevent major accidents from petrochemical industry.
