Construction by nature is inherently dangerous, with a high degree of hazard and risk. Serious fire has occurred in building under construction, which will not delay their completion dates and loss of life, but also result in serious monetary losses. The objectives of this paper are to investigate the causes of fire hazard during the construction phase; assess the risk level arising from the fire hazard during the construction phase; and tpropose safety control measures of fire hazard during the construction phase. Primary data is obtained from the respondents of a mixed use development project in Kuala Lumpur via questionnaire surveys. The data is analysed via Statistical Package for the Social Science (SPSS) and Hazard Identification, Risk Assessment and Risk Control (HIRARC). The findings show that the most important causes of fire hazard of a mixed-use development project are related to workers site activities. Meanwhile, HIRARC identifies that fire hazard from hot works and use electrical tools are the most important risks. Lastly, safety control measures were proposed to control the identified fire hazard by improving the operating procedure of hot works and use of electrical tools as well as implementing good housekeeping practices and inspection at the workplace.

The Impact

The impact that trucks have on crash severity has long been a concern in crash analysis literature. Furthermore, if a truck crash happens in a tunnel, this would result in more serious casualties due to closure and the complexity of the tunnel. However, no studies have been reported to analyze traffic crashes that happened in tunnels and develop crash databases and statistical models to explore the influence of contributing factors on tunnel truck crashes. This paper summarizes a study that aims to examine the impact of risk factors such as driver factor, environmental factor, vehicle factor, and tunnel factor on truck crashes injury propensity based on tunnel crashes data obtained from Shanghai, China. An ordered logit model was developed to analyze injury crashes and property damage only crashes. The driver factor, environmental factor, vehicle factor, and tunnel factor were explored to identify the relationship between these factors and crashes and the severity of crashes. Results show that increased injury severity is associated with driver factors, such as male drivers, older drivers, fatigue driving, drunkenness, safety belt used improperly, and unfamiliarity with vehicles. Late night (00:00–06:59) and afternoon rushing hours (16:30–18:59), weekdays, snow or icy road conditions, combination truck, overload, and single vehicle were also found to significantly increase the probability of injury severity. In addition, tunnel factors including two lanes, high speed limits (≥80 km/h), zone 3, extra-long tunnels (over 3000 m) are also significantly associated with a higher risk of severe injury. So, the gender, age of driver, mid-night to dawn and afternoon peak hours, weekdays, snowy or icy road conditions, the interior zone of a tunnel, the combination truck, overloaded trucks, and extra-long tunnels are associated with higher crash severity. Identification of these contributing factors for tunnel truck crashes can provide valuable information to help with new and improved tunnel safety control measures.

Purpose – This study aims to understand the impacts of the Minor Works Control System (MWCS) on the performance of minor works contractors following its implementation in 2011, and specifically the initiatives adopted by minor works contractors in response to the new building control regime. Suggestions are made for the further improvement of the MWCS. Like many Western countries and Asian counterparts, Hong Kong has recently implemented a new building control system (the MWCS), which aims to restructure the building proposal approval process and shift the responsibility for building control from the public to the private sector. The effectiveness of the MWCS has been strongly questioned by the industry and the public. Design/methodology/approach – A mixed method including a questionnaire survey (quantitative) and focus group discussions (qualitative) was adopted to provide an initial evaluation of the impact of the MWCS on practitioners and the industry. Findings – The results suggest that implementation of the new control system has helped increase safety awareness and the technical capacity of minor works contractors. Despite these benefits, registered contractors are encountering challenges under the MWCS, such as manpower arrangement problems and higher business operating costs. Initiatives that include maintaining a sound financial background, an adequate in-house supervisory staff and a safe working environment are considered critical by practitioners to maintain their competitive edge under the new control regime. Originality/value – This study is one of the first studies in Hong Kong to evaluate the impact of the new building control system. The feedback and suggestions provided by the practitioners and experts during the research provide valuable insights for the government on how to provide support to practitioners under the MWCS to achieve a better built environment in Hong Kong.

The Impact

Purpose: The aims of the study were to identify and evaluate the internal controls used in a computerized accounting system of the SMEs, to identify and evaluate the merits and demerits of the internal controls used in the companies, and to identify the challenges in the implementation of internal control systems in the computerized accounting system of the SMEs. Design/methodology/approach: The population of the study was the employees of the SME’s registered with Ministry of Commerce and Industry (MOCI) in Muscat, Oman. Samples were selected from this population on a random sampling basis. One-member employee from the SMEs representing the enterprise filled the questionnaire. The survey was conducted through a questionnaire using a Google form. 220 samples were collected from the population. The data collected was analyzed using data processing methods and Microsoft excel. Findings: The study found that SMEs were using computers to perform their daily transactions and the accounting software used by SMEs were cheap, of low quality and not proficient enough. One of the components of internal control system, i.e. monitoring was implemented by most of the SMEs and they also stated that they rarely hired an external auditor for auditing because of the expensive auditing fees. It was also stated that the security mechanisms were not properly implemented in the SMEs because of the expensive cost. Research limitations/implications: The study suggested that the Government should emphasize the SMEs to implement a good internal control system. This can reduce the errors and also increase the efficiency of operations. SOX in Omani context should be strictly implemented making it statutory and mandatory for all the SMEs in Oman and such statutory laws will help the auditors to abide by the rules and regulations to be followed. Social Implications : Government should support SMEs through providing education on the importance of internal control systems as most of the employees of SMEs are poorly educated/illiterates. The Government should set a price ceiling to the external auditors on the auditing fees exclusively for SMEs so that they can afford. Originality / Value: No study was carried before in relates to the impact of the internal control system through the computerized accounting system among the SMEs in Muscat, Oman. This study will through light on the statutory laws required for the sake of internal control measures required for the SMEs.

The Impact

This study was carried out to determine the impact of the HACCP control system on the safety of the final products of collagen hydrolysate production. The object of the study was equine connective tissue. Using the FMEA model, established by a three-factor assessment of the risk priority number (RPN), critical control points (CCP) in the processes of hydrolysis, inactivation of the enzyme preparation, drying and storage were identified. For two CCP, measures for continuous monitoring were identified, and critical limits were developed. For CCT 1, the calculation of optimal fermentation processes using a mathematical model for the hydrolysis of raw materials is given. The optimal values of the Neutrase enzyme, providing a maximum content of water-soluble proteins of 55.0 mg/cm3, were determined: T=37 °C, dosage 5 Pa/g, t=210 min. For CCP 2, to avoid protein denaturation during hydrolysis, a critical limit was developed by determining the heat inactivation point and optimum temperature. Experimental analyses show that the inactivation point of the Neutrase enzyme, estimated by the rate of FTN accumulation, which has 20 % at 60 °C, is reached at the 11th minute. As a result of the study, the effect of enzyme preparations on the safety of collagen hydrolysate was also determined. The result confirms that the Neutrase enzyme preparation had a positive effect on all safety indicators compared to the Trypsin enzyme. The optimal parameters for reducing microbiological indicators, pesticides, antibiotic and toxic metals are: T=40 °C, duration 210 min, dosage of the Neutrase enzyme 5 units/Pa. The results can be used in collagen hydrolysate production to better ensure the quality and safety of the final product

To the article the results of the theoretical and experimental researches are given on questions of estimates of the dynamic rate effect of raindrop impact on soil. The aim of this work was to analyze the current methods to determine the rate of artificial rain pressure on the soil for the assessment of splash erosion. There are the developed author’s method for calculation the pressure of artificial rain on the soil and the assessment of splash erosion. The study aims to the justification of evaluation methods and the obtaining of quantitative characteristics, prevention and elimination of accelerated (anthropogenic) erosion, the creation and the realization of the required erosion control measures. The paper considers the question of determining the pressure of artificial rain on the soil. At the moment of raindrops impact, there is the tension in the soil, which is called vertical effective pressure. It is noted that the impact of rain drops in the soil there are stresses called vertical effective pressure. The equation for calculation of vertical effective pressure is proposed in this study using the known spectrum of raindrops. Effective pressure was 1.4 Pa for the artificial rain by sprinkler machine «Fregat» and 5.9 Pa for long distance sprinkler DD-30. The article deals with a block diagram of the sequence for determining the effective pressure of rain drops on the soil. This diagram was created by the author’s method of calculation of the effective pressure of rain drops on the soil. The need for an integrated approach to the description of the artificial rain impact on the soil is noted. Various parameters characterizing drop erosion are considered. There are data about the mass of splashed soil in the irrigation of various irrigation machinery and installations. For example, the rate (mass) of splashed soil was 0.28…0.78 t/ha under irrigation sprinkler apparatus RACO 4260–55/701C in the conditions of the Ryazan region. The method allows examining the environmental impact of sprinkler techniques for analyzes of the pressure, caused by raindrops, on the soil. It can also be useful in determining the irrigation rate before the runoff for different types of sprinkler equipment and soil conditions.

BACKGROUND COVID-19 represents a serious threat to both national health and economic systems. To curb this pandemic, the World Health Organization (WHO) issued a series of COVID-19 public safety guidelines. Different countries around the world initiated different measures in line with the WHO guidelines to mitigate and investigate the spread of COVID-19 in their territories. OBJECTIVE The aim of this paper is to quantitatively evaluate the effectiveness of these control measures using a data-centric approach. METHODS We begin with a simple text analysis of coronavirus-related articles and show that reports on similar outbreaks in the past strongly proposed similar control measures. This reaffirms the fact that these control measures are in order. Subsequently, we propose a simple performance statistic that quantifies general performance and performance under the different measures that were initiated. A density based clustering of based on performance statistic was carried out to group countries based on performance. RESULTS The performance statistic helps evaluate quantitatively the impact of COVID-19 control measures. Countries tend show variability in performance under different control measures. The performance statistic has negative correlation with cases of death which is a useful characteristics for COVID-19 control measure performance analysis. A web-based time-line visualization that enables comparison of performances and cases across continents and subregions is presented. CONCLUSIONS The performance metric is relevant for the analysis of the impact of COVID-19 control measures. This can help caregivers and policymakers identify effective control measures and reduce cases of death due to COVID-19. The interactive web visualizer provides easily digested and quick feedback to augment decision-making processes in the COVID-19 response measures evaluation. CLINICALTRIAL Not Applicable
