In this study, three Line Operations Safety Audits (LOSAs) on an airline are carried out, their results are compared with each other, and a comparison is also made between domestic and international fleets. The LOSA is a proactive and predictive method in the Safety Management System that detects the strengths and weaknesses of airline performance under normal operations. Furthermore, it is a tool to improve the safety margin. The LOSA process is implemented on the basis of ten operating characteristics. Once the data for each LOSA was gathered and processed, the results for the three were compared. Surveys show that LOSAs provide a monitoring system for the Threat and Error Management of old generation aircraft. Domestic and international airline fleets confront different types of threats and errors in different flight phases. It is concluded that the syllabuses of training courses should be different for flight crew with respect to their fleet and the threat and error types. That are most common the obtained results can promote the importance of airlines’ Threat and Error Management based on their fleet type in the future.

Purpose: Dispatch Operations Safety Audit (DOSA) is a proactive and predictive method in safety management system that detects the capabilities and pitfalls of dispatcher performance. In this study, Dispatch-Line Operations Safety Audit is carried out in an airline and results are analyzed and discussed.Design/methodology/approach: The method of DOSA implementation for flight operations officers is similar to LOSA for flight crew.Findings: Results show that DOSA has an important effect on Threat and Error Management (TEM) in the Operations Control Center (OCC).Originality/value: Potential applications of this research include the better threat and error management in OCC with the implementation of DOSA as well as identification of threats and errors types for FOOs in OCC. Also distribution of threats and errors in different phases of dispatch shift is discussed, therefore syllabuses of training courses can be provided with respect to threat and error types for flight operations officers.

Abstract Background The identification of the homogeneous and heterogeneous risk factors for different types of metastases in colorectal cancer (CRC) may shed light on the aetiology and help individualize prophylactic treatment. The present study characterized the incidence differences and identified the homogeneous and heterogeneous risk factors associated with distant metastases in CRC. Methods CRC patients registered in the SEER database between 2010 and 2016 were included in this study. Logistic regression was used to analyse homogeneous and heterogeneous risk factors for the occurrence of different types of metastases. Nomograms were constructed to predict the risk for developing metastases, and the performance was quantitatively assessed using the receiver operating characteristics (ROC) curve and calibration curve. Results A total of 204,595 eligible CRC patients were included in our study, and 17.07% of them had distant metastases. The overall incidences of liver metastases, lung metastases, bone metastases, and brain metastases were 15.34%, 5.22%, 1.26%, and 0.29%, respectively. The incidence of distant metastases differed by age, gender, and the original CRC sites. Poorly differentiated grade, more lymphatic metastasis, higher carcinoembryonic antigen (CEA), and different metastatic organs were all positively associated with four patterns of metastases. In contrast, age, sex, race, insurance status, position, and T stage were heterogeneously associated with metastases. The calibration and ROC curves exhibited good performance for predicting distant metastases. Conclusions The incidence of distant metastases in CRC exhibited distinct differences, and the patients had homogeneous and heterogeneous associated risk factors. Although limited risk factors were included in the present study, the established nomogram showed good prediction performance.

The development of Internet of Things (IoT) systems is a rapidly evolving scenario, thanks also to newly available low-power wide area network (LPWAN) technologies that are utilized for environmental monitoring purposes and to prevent potentially dangerous situations with smaller and less expensive physical structures. This paper presents the design, implementation and test results of a flood-monitoring system based on LoRa technology, tested in a real-world scenario. The entire system is designed in a modular perspective, in order to have the capability to interface different types of sensors without the need for making significant hardware changes to the proposed node architecture. The information is stored through a device equipped with sensors and a microcontroller, connected to a LoRa wireless module for sending data, which are then processed and stored through a web structure where the alarm function is implemented in case of flooding.

Electronics and communication is the most important field. In this paper, we can describe how much safety is in the Automobile industry. In this paper, we are using uno-Arduino. The different types of sensors facilities are also provided using key points. The different sensors are provided to check visitor count. In this system, we can monitor and control all the safety precautions their one IoT web platform. This helps in the proper utilization of drivers and helps in avoiding accidents. This paper can be implemented in any two-wheelers, heavily loaded trucks, small SUVs, compact cars. In our paper, the electronics machine/components will be automatically working with using of Arduino program. The proposed wireless sensor platform is an attempt to develop more safety devices that can be used in multiple areas such as homes, schools, and public utilities to reduce accidents. This Advanced Driver Assists system will provide real-time accident detections and monitoring usage information that helps in real-time by using GSM, GPS, and sensors.

Since the Government of Indonesia made deregulation in several aspect of aviation industry early of this century, the development of airline industry shows thremendestly. There are many new Low Cost Air Carrier “growing up like mushrum in the rainy season”. Some of side effect of this fast growing are concerning with flight safety, especialy in maintenance, human resources and operational aspects. Flight Safety is mandatory in all aspect of aviation industry, there is no room for relaxation or dispensation regarding safety. Air crew especialy Pilot has huges responsibility in Flight Safety during flight, their healthy condition and eligibility of technical of flight should be maintain at all times. Missuse of narcotic will jeoperdize both healthy and ability in their profesional perform.  In this journal we will focus on human resources aspect regarding legislation of missuse of narcotic among flight crew and implementation of safety management of aviation personel.

All analyzers have strengths and limitations that vary with the technology used, and directly affect their suitability for different types of metabolic rate measurement. It is important for researchers to become familiar with the characteristics of the analyzer(s) they are using. This chapter discusses the chief technologies utilized in aerial gas analyzers for O2, CO2, and water vapor, and their advantages, disadvantages, and operating characteristics. For oxygen analyzers, the single channel and differential heated zirconia cell, single channel and differential fuel cell, and paramagnetic types are described. For carbon dioxide analyzers, the single-wavelength and dual-wavelength nondispersive infrared types are discussed. For water vapor analyzers, the chilled-mirror, infrared and capacitive types are considered.

This paper describes the principles and general operating characteristics of ultrasonic cross-correlation flowmeters for liquids and gases. A great deal of research is currently proceeding to determine the performance of these instruments when measuring different types of fluids, but the general form of results are given for various flow systems. Since there is no restriction to flow and the measurement is largely independent of the fluid properties there is a great deal of interest in applying the technique in industry when suitable ‘peak-seeking’ correlators become available.
