Construction sites are renowned as the noisiest places that may cause hearing loss to workers. Lack of awareness about the level of harmful sounds causes more prevalence of hearing loss than other industries. This article intends to solve this issue by an innovative idea that is designing a wearable device called "smart helmet" (SH). The SH uses the concept of the Internet of things (IoT) for real-time monitoring workers' hearing health in construction sites. SH works online to send notifications in the presence of harmful sounds and offline due to storing data to analyse workers' health conditions. The results are divided into two sections: The first section presents the detail of the architecture, hardware and software of the SH and the second section offers a formula to convert noisy situations into allowable working time. By combining the proposed procedure and SH's prepared data, the allowable working time can be calculated for workers. The results of applying this device in practical projects show that steelworkers are more at risk than the others with exposure to 98 dB sounds.

Abstract This study presents a fuzzy decision-making trial and evaluation laboratory (DEMATEL) analysis of the internet challenges of the internet of things (IoT) implementation of construction projects in Nigeria. The identification of the IoT challenges was carried out through a thorough literature search and discussions with 27 built environmental experts. In addition, DEMATEL, an expert judgement-based tool, was used to pick, design, and evaluate a structural model consisting of a causal relationship between defined IoT challenges. Subsequently, the fuzzy DEMATEL was deployed with a view to constructing a structural relationship between the various challenging factors by visualising the dynamic associations between them. Based on the findings of the literature survey and expert evaluation, 18 obstacles to the implementation of IoT in construction projects were classified into cause and effect classes based on their relative parameters of impact. The results suggest that 8 challenges were categorised into the cause group, while 10 were listed into the impact group. The results of this study will enable construction companies, construction industry experts, project managers in Nigeria to enhance their search to design and execute an effective and productive IoT application for their construction projects.

In adults to the old age, check health conditions such as blood pressure, blood s ugar levels, and others are needed regularly. Medical devices generally only be operated by doctors. Healthcare companies always develop medical devices for efficiency in use and minimize costs in manufacture. In this study, researchers made a design for monitoring blood pressure, non-invasive blood sugar, weight, and body temperature based on the Internet of Things. This tool uses NodeMCU microcontroller, which processes sensor MAX30100 and DS18B20. The MAX30100 sensor is used to detect blood pressure and blood sugar non-invasive. By put finger index on the sensor, the results will display after 20 seconds. DS18B20 sensor is used to measure realtime body temperature by clamp the sensor to the armpit.  Load Cell sensors and the HX711 module are used to measure body weight.Results on measurements on LCD 20x4 and android using the Blynk application with the internet.Test analysis with a compare of the manufacturer's standard tools. The results, accuracy of tool are 94.78% and 93,37% in the measurement systole and diastole, 93,21% in measuring blood sugar, 96,55% in measuring body temperature, and 98,27% in measuring body weight. The results on Android can  display if there is an internet or wifi connection without place restrictions.

The construction industry is the pillar industry of China’s national economy. According to the statistics of the National Bureau of Statistics, the GDP in 2016 was 744.127 billion yuan, while the total construction output value was 193.567 billion yuan, accounting for 6.5 percent of China’s GDP. The construction industry has played a pivotal role in promoting social development. Construction projects have always belonged to typical high-risk industries, and they will be affected by many factors, and these factors are mostly from the social environment and the natural environment, which makes it difficult to realize the expected construction period, cost, quality, safety, etc., of the construction project. The objectives, especially for large- and medium-sized construction projects, involve a lot of specialties, a wide range, a long construction period, and a huge amount of investment. Once the risks appear, the consequences are unimaginable. In addition, construction projects will be affected by accidental factors during the implementation process. If not handled in time, it will seriously affect the normal operation of construction projects. In view of the above problems, this article aims to study the risk management research of construction project management under the multimedia environment of the Internet of Things. Combining the characteristics of mobile construction projects, various problems are analyzed in the construction process of construction projects. This paper proposes a multimedia-based construction project management system, construction project quality management objectives and principles, and schedule risk prediction. The experimental results of this paper show that taking the construction project under the multimedia environment as an example, the communication management and quality control management of the construction project under the multimedia environment are studied. Through the combination of theory and practice, the work of construction projects under the multimedia environment of the Internet of Things is guaranteed to be completed on time and with high quality.

The existing stand-alone multimedia machines and online multimedia machines in the market have certain deficiencies, so they cannot meet the actual needs. Based on this, this research combines the actual needs to design and implement a multi-media system based on the Internet of Things and cloud service platform. Moreover, through in-depth research on the MQTT protocol, this study proposes a message encryption verification scheme for the MQTT protocol, which can solve the problem of low message security in the Internet of Things communication to a certain extent. In addition, through research on the fusion technology of the Internet of Things and artificial intelligence, this research designs scheme to provide a LightGBM intelligent prediction module interface, MQTT message middleware, device management system, intelligent prediction and push interface for the cloud platform. Finally, this research completes the design and implementation of the cloud platform and tests the function and performance of the built multimedia system database. The research results show that the multimedia database constructed in this paper has good performance.

This paper discusses the organisations involved in the development of application standards, European regulations and best practice guides, their scope of work and internal structures. It considers their respective visions for the requirements for future standardisation work and considers in more detail those areas where these overlap, namely human centric or integrative lighting, connectivity and the Internet of Things, inclusivity and sustainability.

The economic diversification concept gives hope for a country with rich natural resources to strengthen its economic basis. Thus industrial revolution era of 4.0 provides great opportunity to fasten the process. A study by McKensey in 2011 proved that the internet in the developing country contributes around 3.4% towards its GDP which means that the internet has become a new hope for the economy in the future. Indonesia is one of the countries that is attempting to maximize the role of the Internet of Things (IoT) for its economic growth.� The attempt has made the retail and tourism industries as the two main sectors to experience the significant effect of IoT. In the process of optimizing the IoT to support the economic growth, Indonesia faces several issues especially in the term of the internet network quality and its distribution, the inclusive access of financial access and the infrastructure
