Abstract Few studies have examined the relationship between heart rate and self-injurious behavior (SIB) shown by individuals with IDD (intellectual and developmental disabilities). In this single-case study, we simultaneously monitored heart rate and activity levels during a functional analysis of severe skin picking behavior exhibited by a young man with Prader-Willi syndrome (PWS). Results of the functional analysis indicated that the participant's skin picking was maintained by automatic reinforcement. A within-session analysis of the data indicated that skin picking bouts resulted in an increase in heart rate, suggesting a positive- automatic reinforcement function. These data indicate that inclusion of heart rate and activity-level monitoring during a functional analysis may provide important additional information concerning the determinants of SIB.

This paper aims to apply the wavelet transform to the study of driver’s heart rate in different roadside landscape patterns. In the methodology, we describe the procedure in detail that implementing wavelet transform to denoise heart rate signal. The result shows the algorithm presented with the best performance is suitable to process heart rate signal. In the case study, taking advantage of the superiority of wavelet transform in time-frequency domain, it is apparent that heart rate is in a state of fluctuation continuously. That confirms that sensitivity of heart rate measure the mental workload. We also observe that landscape transition enhance driver’s heart rate on a small scale, which makes a positive effect on driver and can be adopted as a countermeasure against the fatigue of driver in the further road landscape design.

This study aims to reduce the physical and mental workload received by workers in the Machine Shop Department. This research is focused on the production process .Measurement of physical workload uses the calculation of the worker's heart rate by calculating the percentage of Cardiovascular Load (CVL). Measurement of mental workload using the National Aeronautics and Space Administration Task Load Index (NASA-TLX) score calculation method. The results obtained based on the aspect of NASA-TLX before the proposal almost all workers receive a mental workload with a value of > 80 that is included in the category of heavy mental workloads except Milling-Drilling Workers (4) have a score < 80 in the category of moderate mental workload. After the proposal all workers have a score < 80 so that the mental workload received falls into the medium category. Based on the proposals applied to the Lathe Worker (1) and the Milling-Drilling Worker (4) namely the improvement of work methods in the process of turning, punching, and the proposed holding of a reminder as a tool to remember, the results obtained %CVL from both workers < 30%. Three other workers, although experiencing a decline, remained at > 30%. The category of mental workload received by workers from previously included in the category of heavy mental workload dropped to moderate

El objetivo de este artículo es el de proporcionar información sobre la carga de entrenamiento a partir del seguimiento de un atleta durante siete meses de preparación para una competición de Ironman (3.8 km de natación, 180 km de ciclismo y 42.195 km de carrera), utilizando una metodología de entrenamiento con registros diarios de variabilidad de la frecuencia cardiaca (VFC). Como variable para evaluar la actividad parasimpática se calculó la raíz cuadrada de la media de las diferencias de la suma de los cuadrados entre intervalos RR adyacentes (RMSSD) y el índice de estrés (SS) como indicador de actividad simpática. En los meses dos, tres y cuatro presentó un moderado incremento del SS (d =1,17) paralelamente a una moderada disminución de la RMSSD (d = -1,04). Para los meses cinco, seis, y siete se observó una pequeña disminución del SS (d = -0,23) y moderado aumento de la RMSSD (d = 1,08). Como concusión es que las mediciones de VFC de cinco minutos al despertar parecen ser una forma útil de monitorizar el estado de equilibrio parasimpático en un triatleta antes de abordar las sesiones de entrenamiento. El análisis de esta monitorización serviría para detectar precozmente posibles estados de fatiga y para poder modificar, en caso necesario, la planificación de las cargas de entrenamiento en la preparación para una competición de Ironman.  Summary. The objective of this article is to provide information on the relationship between external (TL) and internal training load (ITL) from the tracking of an athlete during seven months of preparation for an Ironman competition (3.8 km of swimming, 180 km of cycling, and 42,195 km of running), using a training methodology with daily records of the heart rate variability (HRV). As a variable to assess parasympathetic activity, the square root of the mean of the differences in the sum of the squares between adjacent RR intervals (RMSSD) was calculated, together with the stress score (SS) as an indicator of sympathetic activity. In months two, three and four, there was a moderate increase in SS (d = 1.17) parallel to a moderate decrease in RMSSD (d = -1.04). In months five, six, and seven, a small decrease in SS (d = -0.23) and a moderate increase in RMSSD (d = 1.08) were observed. As a conclusion, the five-minute HRV measurements upon awakening appear to be a useful tool to monitor the state of parasympathetic equilibrium in a triathlete before approaching training sessions. The analysis of this monitoring would serve to detect possible fatigue states in the early stages and to modify, if necessary, the training load planning in preparation for an Ironman competition.

The Relationship

Shipping is an indispensable tool for the sustainable global supply chain, and seafarers play a key role in safe navigation. Maritime autonomous surface ships (MASS) have been expected to reduce marine accidents by human error of the seafarers. On the other hand, MASS may have adverse effects on operators’ mental workload (MWL) and increase safety risks in some cases. This research aims to provide a scheme for identifying the relationship between MWL and MASS in the maritime that can be utilised for rulemaking and technological development. The provided scheme identifies the factors that affect the MWL of operators and sub-elements of MWL through gap analysis. Five factors related to MASS operation were defined, in addition to general factors. The case study was carried out by utilising the scheme on typical cases focusing on the normal navigational situation. The NASA task load index method was used to measure MWL. Ten deck officers with various ranks, including the third officer and captain, participated in the case study. The results suggested that various causes such as conflicted situations, machine–human interfaces, mechanical-style movements of the ship, reliability of MASS, and visibility constraints affect the MWL of operators. It also confirmed the verification of the identification scheme.

Wheelchair Athlete

This study, with a top T-52 class athlete, determines the relationship between stroke frequency (SF) and push time (PT) and wheelchair velocity (Wv) using different handrim diameters (HD) and the effect of different HDs on the athlete’s heart rate (HR) and blood lactate (LACT) at competition speeds. Wv shows a linear-direct relationship with SF but a linear-inverse relationship with PT (p < .001 in both cases). Using bigger handrims (0.37 m instead of 0.36 m), SF increases 6%, while PT decreases 27% (at 24 Km·h–1). HR (p < .0001) increases with Wv and is also affected by HD with differences between the 0.34 m—0.36 m handrim group (lower values) and the 0.37 m handrim (higher values). Significant interaction (p < .0001) is identified between HD and Wv. LACT results seem to follow the same direction as HR. This methodology helped the athlete to choose the optimum HD, and his achievements (some world records) indicate that HD optimization could be highly profitable in sport terms.

Introduction: Currently, Culinary becomes a promising business, so does Lamongan Kaliotik Resto, one of the famous restaurant in Lamongan. The high number of customer visits risks the workforce from work fatigue. The demand for production in order to fulfill the consumer needs leads to an excessive workload which is handed to the workers in the Kaliotik Lamongan restaurant. Moreover, high mobility in the food production process potentially creates non-ergonomic work attitudes. Therefore, all of those factors can lead the workers experiencing work fatigue. The purpose of this study was to analyze the relationship between workload and work attitude with work fatigue at Kaliotik Lamongan Resto workers. Methods: This study was observational descriptive which was done by using cross-sectional. The population in this study was all workers at the Kaliotik Lamongan Resto, which consisted of 13 people who worked in the kitchen and cashier kitchen section. The sampling technique used was the total population technique. Data collection includes physical workload measurements, assessment of work attitude with The Rapid Upper Limb Assessment (RULA) method and work fatigue measurements using a reaction timer. The study was analyzed using the Spearman correlation test. Results: Showed that the workload with work fatigue had a relationship with the strength of the moderate relationship (r = 0.415) and work attitudes with work fatigue showed a low strong relationship (r = 0.389). Conclusion: Excessive workload is the main factor which causes work fatigue in workers, in contrary, work attitude is not a factor of work fatigue.Keywords: physical workload, work attitude, work fatigue

High Stress Level

This type of activity or work with high stress level and requires more concentration and attention, in this case is the aircraft operation. Thereby mental workload is the most dominant than the physical workload. And this is what should have been a concern, because if mental workload endured by pilot is excessive, it will lower down the quality of work and lead to work safety;  in this case the aircraft operation. Subjective Workload Assessment Technique (SWAT) method is used to measure mental workload value, this method consists of three dimensions with their levels, there are: time, mental effort, and psychological stress load. The aim of this study was to know the mental workload of the pilot of an aircraft in flight dimensions: phases of time, phase of flight, terrain condition, and weather, and identifies what factors the most dominant for build of mental workload. The results of studies showed that pilot mental workload will increase when a pilot faced with flight conditions do at early morning (00.00-05:59 am), during weekend and enters the peak season period, and the aircraft will be landing procedures, and also in case of change of wind conditions in flight, and will increasingly when pilot exposed to aircraft operating with route condition which has a land surface is mountainious. This study also showed that the time dimension factor (T) significantly affects the mental workload of pilots, indicating that they put more emphasis on this factor when they are considering workloads.

In this article, we report on a multimethod qualitative study designed to explore the emotional experiences of students in the classroom setting. The purpose of the study was threefold: (1) to explore the correspondence among nonverbal expressions, subjective feelings, and physiological reactivity (heart rate changes) of students’ emotions in the classroom; (2) to examine the relationship between students’ emotions and their competence and value appraisals; and (3) to determine whether task difficulty matters in emotional experiences. We used multiple methods (nonverbal coding scheme, video stimulated recall interview, and heart rate monitoring) to acquire data on emotional experiences of six grade 7 students. Concurrent correspondence analyses of the emotional indices revealed that coherence between emotional response systems, although apparent, is not conclusive. The relationship between appraisals and emotions was evident, but the effect of task difficulty appears to be minimal.
