Background: The most essential part of manufacturing the products is grinding. Health and safety of workers are the most important issues in this unit now a days. High productivity as well as maximum turnover is the highest interest of these units. Target oriented work puts some pressure on the workers that also increase their muscular and body stresses.  Methods: The research work was done in different small-scale grinding units in West Bengal. The snap shot of 20 workers in different grinding units was obtained and evaluated with the help of rapid upper limb assessment. NIOSH’s discomfort survey method was used for mapping the different areas of pain, dissatisfactions during the operation. Heart rate and postural stresses were also noticed.  Results: This research work also shows that the poor working conditions enhance the body stresses and the discomfort level of grinders. The highest heart rate also indicates the poor health condition of grinders. Poor environmental conditions, specially noise and heat were common in grinding units.  Conclusions: It can be concluded that MSDs were present in the activities carried out in grinding units where the major number of workers were involved in bad body postures. This research work also shows that the poor working conditions enhance the body stresses and the discomfort level of grinders.

Small-scale contractors (SSCs) require management strategies in implementing occupational health and safety (OH&S) performance at projects to reduce accidents, injuries, fatalities and diseases. Management strategy success factors have been acknowledged to be of great benefit in improving in OH&S performance. Hence, the study sought to assess the management strategy success factors for the improvement of OH&S performance by SSCs in Zambia’s electricity industry. Using quantitative methods, data was collected using a survey questionnaire from 246 respondents representing firm owners, managers, project managers and OH&S representatives at electricity industry projects at 70.3% response rate. Descriptive and inferential statistics were adopted as methods of data analysis using exploratory factor analysis. After analysis, the success factors were clustered into three construct categories within OH&S performance namely, compliance and workplace processes, policy and human resource development, and leadership and structure significant values ranging from 0.513 to 0.972. The independent reliability was tested using the Cronbach Alpha coefficient. The study exposed management strategy success factors are well recognised by most SSCs and contributed to the body of knowledge in this mastery by introducing three success factors for OH&S performance. It is recommended that these factors be adopted and considered to improve OH&S performance management by SSCs in the electricity industry in Zambia.

This chapter looks at the health and lifestyle factors among tea garden labourers in West Bengal. Tea garden labourers enjoy access to some free facilities like education for children, medical facilities, piped drinking water, housing, and subsidised food. Yet they still suffer from several health problems. This might be due to insufficient or inadequately maintained facilities, poor lifestyles, or a mixture thereof. The chapter then focuses on the work environment, lifestyles, and physical health status of Oraon tea garden labourers of Jalpaiguri district, West Bengal. The results reveal that around 60 per cent of the labourers are underweight, despite reporting that they were getting sufficient food to eat. Poor hygienic practices may explain these results. Anaemia was also high for both sexes. Ultimately, the overall health condition of the labourers may be explained by the poor health lifestyles that they have adopted in response to their work environment.

Measurement Results

Heart rate and body temperature can be used to determine the vital signs of humans. Heart rate and body temperature are two important parameters used by paramedics to determine the physical health condition and mental condition of a person. Because if your heart rate or body temperature is not normal then you need to make further efforts to avoid things that are not desirable. The purpose of this study is to design a heart rate and body temperature. In this study, the heart rate is detected using a finger sensor which placed on the finger. This sensor detects the heart rate pulses through infrared absorption of blood hemoglobin, and measure the body temperature using a DS18B20 temperature sensor which is placed axially. DS18B20 sensor works by converting temperature into digital data. The measurement results will be displayed on liquid crystal display (LCD) 2 x 16 and the data will be sent to android mobile phone via Bluetooth.  After the comparision beetwen the desain and the standart, the error is 0.46% for beats per minutes (BPM) parameters and 0.31 degrees Celsius for temperature parameters.

This research work investigates into the servicescape and customers’ willingness to pay for mechanical services at the Suame Magazine in the Kumasi Metropolis. The study adopted descriptive survey method and the target population was the mechanics and customers of mechanical services in the Suame Magazine in the Kumasi Metropolis. The study conveniently sampled 150 customers who patronize the services of the small scale auto mechanics who repair and maintain vehicles. Questionnaire was used to collect data from the customers. It was realized that signs, symbols and artifacts were not important to customers who go to the Suame Magazine for mechanical services but customers’ perceived ambient conditions and spatial layout as important to them. Customers disagree that Suame Magazine smell badly but they attested that the Suame Magazine is noisy. Suame Magazine has good layout but customers attested that the industrial enclave is always congested. Majority of customers’ relatively perceived charges or price of mechanical services to be relatively as expected and majority (58.0%) of the customers were willing to pay for mechanical services at the Suame Magazine. The customers’ willingness to pay for mechanical services depends on the servicesscape in the Suame Magazine. Mechanical garages with good ambient and spatial layout would have high patronage. The study recommends that mechanics in the Suame Magazine should strategically use servicescape as marketing tool for effective pricing which can influence customer willingness to pay for their services. The mechanical garages should have servicescape policy with specific emphasis on spatial layout and ambient conditions.

<p>This study investigates the feasibility of photoplethysmogram (PPG) signals in monitoring health condition and designing a portable health monitoring kit which is suitable for home use. The aim of this study is to ease people in monitoring their health continuously without the need to go to the hospital which can save a lot of time. The focus of this study is to find heart rate and blood pressure recording. The type of PPG sensor used in this project is a non-invasive PPG which measures the blood volume changes in any part of the body. A total of 16 subjects consisting of male and female with age range of 20 to 60 years old were involved in this research. The heart rate and blood pressure for each subject were acquired and analyzed. Based on the result, it shows that higher heart rate reading is associated with female and younger age groups. Meanwhile, for blood pressure value, male subjects tend to have higher blood pressure as compared to female subjects. However, there is no specific pattern for blood pressure in terms of the age group. In the case of HRV analysis based on Kubios software, the SDNN value is higher for male and older age subjects. Meanwhile, the RMSSD value is lower for male and older age subjects. Therefore, PPG signal has the capability to monitor the health status of an individual, which acts as an alternative biological signal for the existing health monitoring systems.</p>

Temperature control system is nothing but a complicated process which is aimed to maintain the temperature in a particular defined area to a certain maxima or minima level or say defined in a range which is quite certain. We can witness this process commonly used in many parts of the India and many other countries. In recent times, we are witnessing a rapid growth in industries at global level which has led to globalization and industrialization which further has led the necessary use of the temperature control system and its application in these industries at day-to-day level in manufacturing and maintenance with the increase in the greenhouse effect and depletion of ozone layer. Many factories both at small scale as well as at large scale always maintain a certain area or say a section of operation in their infrastructure that must maintain a range of temperature for process to work successfully. The laboratories of research uncertainly sometimes lack in the use of temperature control system which has further necessitated the use of large chambers of different sizes to perform specific temperature related re-search work which further led to the increase in the cost of research work. In certain specific areas there are lot of electronic activities happening or some machinery function like in the server rooms or the area where production plant is, so basically these places work constantly for 24hrs and during the whole day the temperature has to be monitored precisely and frequently so that it can be ensured that the temperature do not instantly rise or fall below the marked temperature which may lead to the acceleration of wearing and tearing of whole system. Living rooms, hospitals, malls, aircrafts etc., are also one of the most important places where monitoring of temperature is required so as to ensure that the thermal comfort is ensured, and thermal comfort here means that the state of mind which feels satisfied with the temperature in the present environment. This is important because if there will be any dissatisfaction with the thermal environment then it can cause the body to be too warm or too by unwanted heating and unwanted cooling of the equipment may further lead to the functional disbalance.

Vital sign monitoring is an important body measurement to identify health condition and diagnose any disease and illness. In sports, physical exercise will contribute to the changes of the physiological systems, specifically for the vital signs. Therefore, the objective of this study was to determine the effect of physical fatigue exercise on the vital sign parameters. This is significant for the fitness identification and prediction of each individual when performing an exercise. Five male subjects with no history of injuries and random BMI were selected from students of biomedical engineering, Universiti Teknologi Malaysia. Based on the relationship between physical movement and physiology, the parameters considered were heart rate, blood pressure, and body temperature. Subjects were required to run on the treadmill at an initial speed of 4 km/h with an increase of 1 km/h at every 2 minutes interval. The effect of exercise was marked according to the fatigue protocol where the subject was induced to the maximum condition of performance. All parameters were measured twice, for pre and post exercise-induced protocol. The analysis of relationship of each parameter between pre and post fatigue was p<0.05. The results revealed that the heart rate and gap between blood pressure’s systolic and diastolic were greater for all categories except underweight, where the systolic blood pressure dropped to below 100mmHg at the end of exercise. Also, the body temperature was slightly declined to balance the thermoregulatory system with sweating. Hence, the vigorous physical movement could contribute to the active physiological system based on body metabolism. Heart rate and blood pressure presented significant effects from the fatiguing exercise whereas the body temperature did not indicate any distinguishable impact. The results presented might act as the basis of reference for physical exercise by monitoring the vital sign parameters.

The system “LabVIEW based ECG signal acquisition and analysis” is developed to assist patients and doctors in health care. An arrhythmia is an abnormal heart rhythm. It may be so brief that it doesn’t change the overall heart rate, but it can cause the heart rate to be too slow or too fast. When arrhythmias are severe or last long enough, the heart may not be able to pump enough blood to the body. This can cause the patient to feel tired, lightheaded or may make him pass out. It can also cause death. Before treatment, it’s important for the doctor to know where an arrhythmia starts in the heart and whether it’s abnormal. An electrocardiogram (ECG) is often used to diagnose arrhythmias. “LabVIEW based ECG signal acquisition and analysis” is meant to acquire ECG signals from the patient and analyze it to detect and classify its anomalies and abnormalities. This is achieved by extracting amplitudes and durations of parameters of ECG waveform such as P wave, QRS complex, RR interval, and PR durations. These parameters are compared with the normal values to determine the type of abnormality- Tachycardia or Bradycardia. The database of the patient is maintained for further use by the doctor. The objective of LabVIEW based ECG signal acquisition and analysis aims at acquiring and analyzing temporal parameters of ECG signal such as P wave, QRS complex, RR interval, PR durations and amplitudes of the P wave, ST wave, identification of cardiac arrhythmia using LabVIEW. The research work has helped us to explore various features of LabVIEW like signal processing and automated database generation.

Examination of vital signs such as blood pressure, heart rate, and body temperature is the most basic essential function of the body in determining the health status of the patient. In general, examining vital signs performed by a doctor or nurse uses an electrocardiogram, thermometer, and sphygmomanometer. However, this tool has a weakness in terms of time efficiency and accuracy of reading vital sign data. The process of taking vital sign data for a long time, the limited number of medical personnel in handling patients, and increasing administrative costs certainly become a concern for management in improving health services. To overcome this problem, we proposed a design that can monitor the health condition of patients' vital signs efficiently and in real time. The system used in this study consisted of an HRM-2511E type heartbeat sensor in pulse units per minute (bpm), DS18b20 body type temperature sensor in degrees Celsius (0C), and MPX5700AP sensor in mmHg units. This research is fundamental and is useful in helping medical personnel in monitoring patients' vital sign health conditions. The results of the proposed design showed that the heart rate, temperature, and blood pressure devices worked well with respective accuracy of 97.64%, 99.51%, and 97.53%.

Heart rate (HR) is an essential indicator of health in the human body. It measures the number of times per minute that the heart contracts or beats. An irregular heartbeat can signify a severe health condition, so monitoring heart rate periodically can help prevent heart complications. This paper presents a novel wearable sensing approach for remote HR measurement by a compact resistance-to-microcontroller interface circuit. A heartbeat’s signal can be detected by a Force Sensing Resistor (FSR) attached to the body near large arteries (such as the carotid or radial), which expand their area each time the heart expels blood to the body. Depending on how the sensor interfaces with the subject, the FSR changes its electrical resistance every time a pulse is detected. By placing the FSR in a direct interface circuit, those resistance variations can be measured directly by a microcontroller without using either analog processing stages or an analog-to-digital converter. In this kind of interface, the self-heating of the sensor is avoided, since the FSR does not require any voltage or bias current. The proposed system has a sampling rate of 50 Sa/s, and an effective resolution of 10 bits (200 mΩ), enough for obtaining well-shaped cardiac signals and heart rate estimations in real time by the microcontroller. With this approach, the implementation of wearable systems in health monitoring applications is more feasible.
