Relationship between age and length of working with work fatigue among workers in the motorcycle spare part industry

Fatigue is the inability to function optimally because of the use of physical and mental energy beyond existing capacity. Internal factors have a very important role because they are one of the things that cannot be separated from employees. Some things that are included in the internal factors of workers include age and length of work. The purpose of this study is to analyze the relationship between age and length of work with work fatigue among workers in the motorcycle spare parts industry. The type of study used was an observational analysis with a cross-sectional research design. The population in this study were spare part industry workers, with a total of 27 workers who were also in the research sample. The results of this study indicate that the majority of workers are over 40 years old, have a working duration of eight hours, and experience moderate levels of fatigue. There was a weak relationship between age and work fatigue, with a p-value of 0.041 and a correlation coefficient of 0.396. In addition, there was no relationship between the length of work and work fatigue, with a p-value of 0.174 and a correlation coefficient of 0.386. Companies are expected to provide a limit on overtime work, which is three hours in one day, and provide short breaks between jobs. Additionally, workers are expected to make the best use of their rest time and stretch their muscles between jobs.

Full blood count and some haemorheologic variables of vendors exposed to liquefied petroleum (cooking) gas: a comparative study

Introduction: Cooking gas in the form of liquefied petroleum gas is sold in gas stations and outlets by vendors who do not use personal protective equipment despite working in a high-risk environment hence they have a high exposure to inhalation of the chemicals in the gas. This study assessed the full blood count and haemorheologic variables of vendors exposed to liquefied petroleum gas. Methods: Forty gas vendors were enrolled from four gas stations in Calabar while forty apparently healthy individuals who do not work in gas-related jobs were recruited as control. Ethical approval was granted by the Cross River State Ministry of Health, Calabar. Permission to enroll workers was obtained from the management of gas stations while study subjects gave informed consent. A structured questionnaire was used to obtain demographic information and health history while blood pressure, weight and height were measured using standard instruments; the body mass index was calculated. The full blood count and haemorheologic variables were determined by standard methods. Data analysis was done using a student t-test on SPSS version 21 and a P value ≤0.05 was considered significant. Results: The mean age was 25.9±3.2 years and 26.5±6.5 years for the test and control groups with gas vendors being predominantly males (97.5%). Work duration of 97.5% of gas vendors was ≤5 years. Sixty percent of the control and 42.5% of the gas vendors engaged in regular exercise while 40% and 57.5% do not. Sixty-seven-point five percent (67.5%) of the control rarely go for medical checks and 27.5% had never had a medical check with only 2% who check often. For the gas vendors, 55% have never had a medical check while 45% of them rarely check. Also, 42.5% of the control have never or rarely checked their blood pressure while 15% check often; 62.5% of the gas vendors have never checked their blood pressure while 37.5% rarely check. There was a family history of hypertension for 2 (5%) of the control and none for the test group. Also, 1 (2.5%) of the gas vendors had a history of fainting episodes while 39 of them and the control did not. Only 10% and 20% of the gas vendors use nose mask and hand gloves with the use of overalls and safety boots being 40% for each. The body mass index of the control group (25.15kg/m2) was not different (P>0.05) from that of the test group (24.53kg/m2). Whereas the systolic blood pressure was higher for the gas vendors than the control (126.47mmHg and 120.32mmHg), the diastolic blood pressures were comparable (74.60mmHg versus 72.92mmHg). The full blood count shows the red blood cell count, haematocrit and haemoglobin of the gas vendors were significantly higher (P<0.05) than the control value while the mean corpuscular volume and mean corpuscular haemoglobin were comparable (P>0.05). Again, the mean corpuscular haemoglobin concentration and red cell distribution width standard deviation of the gas vendors were significantly higher (P<0.05) versus the control while the red cell distribution width coefficient of variation was comparable (P>0.05). The total white blood cell count and the absolute granulocyte and lymphocyte counts of the gas vendors were significantly higher (P<0.05) than the control value while the mixed leucocyte count was not different (P>0.05) between the two groups. The platelet count, mean platelet volume, platelet distribution width, plateletcrit, platelet large cell ratio and platelet large cell count were significantly higher (P<0.05) for the gas vendors when compared to the control. Relative plasma viscosity and fibrinogen concentration were significantly higher (P=0.030) when the test group was compared to the control. Conclusions: This study has demonstrated an increase in red cell, white cell and platelet parameters of vendors exposed to cooking gas as a probable response to an induced state of chronic inflammation. There is also impaired haemorheology as expressed by an increase in relative plasma viscosity and fibrinogen concentration with possible pre-disposition to cardiovascular disease as a consequence. Management of cooking gas stations and the vendors should be educated on the need to use personal protective equipment in order to reduce exposure to the components of cooking gas.

Analysis of operation modes of shunting diesel locomotives when performing shunting work

An overview of modern trends in updating shunting locomotives, which are based on the installation of on-board energy storage devices, multi-diesel propulsion power plants, and power plants operated on hydrogen energy sources, was carried out. The necessity to take into account the operating conditions of a shunting diesel locomotive when choosing an upgrade option is shown. The operation modes of shunting diesel locomotives during shunting operations at the Козятин-I freight station during three shifts were considered. By analyzing the data of the БІС-Р onboard system and processing the route sheets, the parameters of the operating modes were determined. Calculations of diesel engine power utilization indicators were performed, according to which it was determined that the full use of the installed diesel generator power is 7.5...8.4%, and the maximum diesel power recorded under the studied operating conditions is about 50%. The duration of work with traction loads is 49.5...68.8% of the shift time. The longest - 55...60% of the total duration of work under traction - are modes with a power of 0...50 kW. The duration of work without load is 18.1...36.9% of the duration of the shift. The shunting work performed is related to the formation and disassembly of trains, including the use of a sorting slide, as a result of which the traction power transmission operates with a low efficiency. In order to reduce the consumption of fuel and energy resources when performing shunting work, it is necessary to update the fleet of locomotives for shunting work, the characteristics of which are adapted to the operating modes. Key words: hybrid locomotive, modernization, shunting, energy efficiency, energy storage

Impacts of Pandemics on Healthcare Workers in Teaching Hospitals in Rivers State, Nigeria: Perspective from Healthcare Workers’ Experience during Pandemics

Background: Pandemics are wide-ranging incidences of infectious diseases that significantly increase morbidity and mortality in extensive geographic area. The study assessed impacts of pandemics experienced by healthcare workers in teaching hospitals in Rivers State, Nigeria.
 Materials and Methods: This study was conducted among healthcare workers in teaching hospitals (University of Port Harcourt Teaching Hospital (UPTH) and Rivers State University Teaching Hospital (RSUTH) in Rivers State Nigeria. Multi-stage sampling method was adopted to recruit 754 healthcare workers into the study, and a descriptive cross-sectional study design was used. A structured questionnaire was developed and pre-tested. The reliability of the questionnaire for this study was performed with the index of internal consistency and was calculated with Cronbach’s alpha coefficient which gave a considerable value of 0.72. The responses gotten from the participants were entered into, and analysed with IBM Statistical Package for Social Sciences (SPSS) software version 25. Ethical clearance to conduct the study was gotten from the Research and Ethics Committee of the University of Port Harcourt. Informed consents were obtained from each of the participants.
 Results: Most (62.2%) of the participants experienced psychological impact of pandemics, (59.4%) of the participants experienced emotional impact of pandemics, (54.5%) of the participants experienced financial impact of pandemics and the overall (58.2%) of experienced impact of pandemics on the HCWs was obtained. Also, the result revealed a statistically significant association between marital (p=0.0001), sex (p=0.003), religion (p=0.0001), level of education completed (p=0.039), income (p=0.0001), professional category (p=0.0001), duration of work (p=0.0001) and overall experienced impact of pandemics on the participants. We predicted that among the participants, marital status, sex, religion, education, income professional category, and work duration at (p≤ 0.05), significantly contributed to the level of experienced impact of pandemics among the participants.
 Conclusion: Majority of the healthcare workers reported impact of pandemics. However, psychological impact of the pandemics was most prevalent impact experienced by the healthcare workers who took part in this study. The level of impact of pandemics experienced by the health workers were substantially influenced by their socio-demographic characteristics. We recommend hospital management should improve the work setting and provide necessary support to the workers. Also, the healthcare workers should participant trainings on coping strategies during pandemics.

Воспроизводство трудовых ресурсов: к вопросу о социологическом подходе

The article presents the experience of applying sociological analysis in relation to one of the central concepts of labor economics – the reproduction of labor resources. Accordingly, the three stages of this phenomenon – formation, distribution and usage – are characterized by the processes occurring at each of the designated stages. The importance of paying attention to these social aspects of the implementation of the stages of re-production processes in the field of labor resources for a more balanced consideration and coordination of the interests of social groups to solve problems in the labor sphere is shown. The discussion of the issue of work-ing time duration from the perspective of historical concepts (K. Marx, E. Durkheim) and modern scientific community is considered. Conclusion dwells upon the fact that reproduction of labor resources is impossible without compliance with a number of conditions, including the optimal ratio of material remuneration and quali-fication of an employee, providing opportunities for professional growth and accumulation of knowledge, set-ting standards for working hours based on labor productivity.

WORK FATIGUE: AN ANALYTICAL STUDY OF WORKERS AT PT. DISTRIBUSI ENERGI MANDIRI, MAKASSAR CITY, INDONESIA

Work fatigue is a work-related tiredness that can become severe, inflict sleeping problems, and even threaten workers’ lives. The International Labor Organization (ILO) recorded annual deaths of approximately two million workers due to fatigue-induced accidents. The authors studied the factors promoting work fatigue in workers at PT. Distribusi Energi Mandiri (DEM) using an analytic survey method. This involved the entire workers as the study population and a questionnaire as the data collection method. In our findings, the chi-square test analysis revealed that work duration (p= 0.718 ( 0.05)), age (p= 1.000 ( 0.05)), and work posture (p= 0.176 ( 0.05)) have no relationships with work fatigue, but not with workload (p= 0.003 ( 0.05)). We, therefore, suggested that the management of PT. DEM continues and maintains the ongoing work duration, but provides assistive devices to workers with excessive workloads. In addition, it is necessary to supervise them to change body positions, stretch up and rest periodically during work. We advised workers to take proper breathing and intake, along with paying attention to occupational health and safety.

Assessment of the Significance of Identified Attributes Affecting the Rebar-Fixing Productivity Using Multiple Regression

Reinforced concrete structures are an inherent part of the construction sector. Every in situ reinforced concrete structure cardinally involves rebar-fixing works, which entails activities like transporting, marking, laying, and tying the rebar for the components under construction. Rebar-fixing absorbs a significant number of man-hours during the operation. Therefore, productivity of rebar fixers is a critical concern in construction. Several attributes influence rebar-fixing productivity. Former studies have investigated the impact of the attributes separately and predominantly using qualitative data. A few studies have assessed rebar productivity quantitatively but ignored the effects of some crucial parameters, such as congestion, crew composition, and construction delays. Moreover, studies are limited to account for all time proportions like productive, semiproductive, and nonproductive while assessing rebar productivity. Therefore, this study addresses the aforementioned research gaps by assessing the impact of diverse attributes using direct measures of rebar-fixing productivity and its attributes. Initially, hypotheses were developed to determine the influence of eight attributes identified in this study on rebar-fixing productivity. Next, the data were recorded from one large construction project in Gujarat, India. The work sampling approach was adopted for the productivity assessment of rebar fixers at the project site to evaluate each time proportion. Furthermore, the stepwise regression analysis was performed on the data set to examine the hypotheses. Results indicate that attributes such as quantity of reinforcement, characteristic rebar diameter, and congestion have a significant positive impact on rebar-fixing productivity, whereas work duration has a significant negative impact on it. The outcomes of this research can aid the site management, structural engineers, and construction planners in decision-making to enhance the productivity of rebar fixers, thereby adhering to the budget and schedule constraints of the project.

Обоснование списочного парка насосов и трубопроводных ставов рудничной водоотливной установки

The complex of drainage system of an underground mining enterprise ensures the safety and continuity of mining operations. Deterioration of the level of reliability of the functioning of the mine drainage system can lead to the following serious consequences. The main link of the mine drainage system is a drainage system equipped with pumping units based on the centrifugal pumps. One of the main criteria for the safe operation of a mine drainage system is its equipment with a sufficient number of pumping units. An assessment of the efficiency of the classical methodology for calculating the listed park of pumping units is given, including consideration of the amendment made to it regarding the given water inflow regime. The main drainage installation of the Udachny underground mine, equipped with sectional pumps, was chosen as the object of research. It is established that the list park of pumping units calculated according to the known methods does not allow to ensure a high level of reliability of the operation of the drainage plant. The same picture is typical for the park of discharge pipe sections of the drainage plant. When calculating the list park of pumping units of a drainage system, it is more expedient to consider not the passport performance of the pump, but its average value between major repairs. The number of pumps under repair depends on the average duration of repair work and the average time between failures of the pump. A method is proposed for calculating the optimal number of pumping units and pipe sections of a drainage system from the point of view of ensuring its reliable level of functioning. The results of the performed research will be useful to the specialists responsible for the design of drainage systems for underground mines and coal mines in the Russian Federation.

STIRRING OF METAL MELTS FOR IMPROVING THE EFFICIENCY OF THE “LADLE – FURNACE” UNITS Message 2. NEW METHOD FOR ELECTROMAGNETIC STIRRING OF METALLIC MELT IN “LADLE – FURNACE” UNIT

The features of refractory lining’s wear of “ladle – furnace” unit at work on metallurgical mini-plant with intensive stirring of liquid metal by gas and electromagnetic field is studied. It was established that the most affected areas are slag zone, ladle’s bottom, as well as side wall, near which the electromagnetic stirrer is located. The stability of these areas determines the duration of the ladle working between repairs. Recommendations for recovery of the lining’s working layer have been developed. Also, there are formulated the requirements for rationalization of melt stirring modes. Theoretical studying of influence of electromagnetic stirring on heat & mass transfer processes in liquid metal bath of metallurgical aggregates (in particular, during homogenization of alloy in free turbulence mode at input of additives) was investigated. New electromagnetic stirrer was designed in the PTIMA NASU, and it is proposed for technologies of melting and finishing of alloys. The stirrer creates the pulsating magnetic field, and its force lines spread equally intensively both in the horizontal and vertical planes. It is shown that design of developed stirrer, its power supply by industrial frequency 50 Hz, and physical nature of the generated field’s action provide the simplicity of its making and operation. So, new stirrer has essential technical, economic and technological advantages in comparison with known stirrers of travelling magnetic field at the same parameters of electromagnetic systems. Joint research performed by specialists of the PTIMA NASU and IED NASU with using mathematical modeling and experiments on aluminum melt showed the following. It is possible to realize a wide range of stirring modes, both intensity and melt movement directions. Thus, the application of developed electromagnetic stirrer in the “ladle – furnace” units will allow to significantly expand the possibilities for finishing liquid alloys on chemical composition and temperature, especially at small metallurgical plants.

Fractures of the fifth metacarpal neck treated by syndactyly: functional and quality of life outcomes of a series of 39 patients.

The management of the fractures of the fifth metacarpal neck is still debated between surgical, orthopedic, and functional treatments. The main objective of our study was to report the functional results at two, six, and twelve weeks of patients treated with syndactyly for fifteen days for a fracture of the neck of the fifth metacarpal and to determine if these results were compatible with a short-term medical follow-up and if they allowed for a quick return to work. Thirty-nine patients were retrospectively included. Functional results and their variations were analyzed at two, six, and twelve weeks using self-questionnaires filled out during consultation (VAS scores, QuickDASH, EuroQol-5D-5L, and EuroQol- 5D-VAS). The duration of work leave was extracted from medical records. Two weeks after the trauma, patients mostly had a very moderate impact of their fracture on their daily life with an average VAS of 4.2±1, QuickDASH of 42.2±20.9, and EuroQol-5D-VAS of 78±11. QuickDASH and EuroQol-5D-VAS scores showed significant improvement between two and twelve weeks of follow-up, decreasing from 42.2±20.9 to 2.1±6 and from 78±11 to 96±6, respectively (p<0.0001). The dimensions of common activities, pain, and autonomy had the most patients in the "moderate impairment" subgroup at two weeks. Only the dimension of common activities still had 21% of patients moderately impacted. Twenty-five patients returned to work at an average of 21.8±1.5 days. Syndactyly treatment offers good functional results at two weeks that are confirmed during follow-up, compatible with reduced medical follow-up and early return to work.

ANALISIS PERCEPATAN WAKTU PELAKSANAAN PROYEK BERBASIS MICROSOFT PROJECT (STUDI KASUS: PEMBANGUNAN RENOVASI HOTEL LAGUNA RESORT AND SPA NUSA DUA)

In project construction, problems during the implementation phase are unavoidable, resulting in non-compliance with the previously designed plan. In the case study of the construction of the Laguna Resort and Spa Nusa Dua hotel, based on the author's observations, data from the Planned Time Schedule and Realization Time Schedule found differences in the realization time with the plan, where the realization was delayed. In overcoming the delay, it is necessary to accelerate the completion time by accelerating the implementation time and conducting an analysis regarding how much influence the acceleration of completion time has by utilizing the Microsoft Project program. The data used is a quantitative descriptive method, namely by submitting a request for data to the Contractor. From processing the data and conducting 3 experiments on Microsoft Project, the authors chose the second experiment, namely by accelerating the Millwork sub-bill by reducing the average work duration of 1 working day. Activities that experience acceleration are as many as 26 work items including 8 work items on the 1st floor, 6 items on the 2nd floor, 6 items on the 3rd floor, and 6 items on the 4th floor. The results of the accelerated time are 5 (days) according to the time plan schedule

Migrant worker inclusion and psychological well-being: Insights from the hospitality and tourism workplace

While the hospitality and tourism industry relies on migrant workers as a source of labour, their inclusion and well-being are less examined. Set in a hospitality and tourism-dependent economy that heavily depends on migrant workers, this study employed logit models to determine the factors that coalesce to create inclusion in the industry. The findings revealed that formal educational attainment, duration of stay, duration of work with tourism organisation, contribution to creative solutions at the workplace, and assistance to co-workers significantly contributed to workplace inclusion. Two inclusion dimensions of belongingness, and uniqueness, significantly determined the psychological well-being of the migrant workers.

CHANGES IN PROFITABILITY OF THE AVIGNON RESIDENTIAL COMPLEX CONSTRUCTION UNDER THE INFLUENCE OF ORGANIZATIONAL FACTORS

This article is devoted to managing the profitability of the construction of the residential complex "Avignon" in the city of Odessa, located near the seaside, under the condition of changing organizational factors. The residential complex consists of 13 sections arranged in circular shapes, with sports and children's playgrounds in the middle. Each section has two underground levels of parking, except for one atypical section for a commercial pavilion with a structural glass facade. The buildings have a monolithic load-bearing frame, pile foundation, and enclosing structures made of non-removable formwork using a new technology with the use of foam concrete.To manage the profitability of construction, project management software and correlation-regression analysis were used. Modeling was carried out in Microsoft Project, which allows determining the sequence of tasks, estimating the duration of work, calculating the financial movement schedules, and determining the necessary resources. Using the COMPEX program, regularities were built on the change in the intensity of construction financing in accordance with the theory of experimental planning. These regularities allow controlling the duration of construction by changing the intensity of the use of working time and the compatibility of construction processes. Thanks to the data obtained as a result of experimental-statistical modeling regarding the maximum and average intensity of financing, the total cost of construction was determined, taking into account the use of credit funds. Further, when calculating the profitability of construction, the amount obtained as a result of the dependence of construction on all selected factors was used. Profitability was calculated depending on the average price per square meter according to the data of the Ministry of Regional Development. As a result of the research, it was determined that when changing organizational factors (the intensity of the use of working time and the compatibility of processes), the profitability of the construction of the "Avignon" residential complex changes from 11.4% to 41.8%.
