The widespread implementation of advanced and complex systems requires predominantly operators' cognitive functions and less importance of human manual control. On the other hand, most operators perform their cognitive functions below their peak cognitive capacity level due to fatigue, stress, and boredom. Thus, there is a need to improve their cognitive functions during work. The goal of this paper is to present a psychophysiology training approach derived from cardiovascular response named heart rate variability (HRV) biofeedback. Description of resonant frequency biofeedback-a specific HRV training protocol-is discussed as well as its supported researches for the performance enhancement. HRV biofeedback training works by teaching people to recognize their involuntary HRV and to control patterns of this physiological response. The training is directed to increase HRV amplitude that promotes autonomic nervous system balance. This balance is associated with improved physiological functioning as well as psychological benefits. Most individuals can learn HRV biofeedback training easily which involves slowing the breathing rate (around six breaths/min) to each individual's resonant frequency at which the amplitude of HRV is maximized. Maximal control over HRV can be obtained in most people after approximately four sessions of training. Recent studies have demonstrated the effectiveness of HRV biofeedback to the improvement of some cognitive functions in both simulated and real industrial operators.

The aim of this study was to examine the effect of resonant breathing biofeedback training for reducing stress among manufacturing operators. Resonant breathing biofeedback works by teaching people to recognize their involuntary heart rate variability and to control patterns of this physiological response. Thirty-six female operators from an electronic manufacturing factory were randomly assigned as the experimental group (n = 19) and the control group (n = 17). The participants of the intervention received 5 weekly sessions of biofeedback training. Physiological stress profiles and self-perceived depression, anxiety, and stress scale (DASS) were assessed at pre- and post-intervention. Results indicated that depression, anxiety, and stress significantly decreased after the training in the experimental group; they were supported by a significant increase in physiological measures. Overall, these results support the potential application of resonant biofeedback training to reduce negative emotional symptoms among industrial workers.

BACKGROUND: Predominantly cognitive tasks assigned to the shop floor can lead to decreased cognitive functions problems, thereby increasing occupational accident risks. A potential approach to prevent such circumstances is by improving operator's cognitive performance. OBJECTIVE: This study aimed to examine whether heart rate variability (HRV) biofeedback training could improve cognitive performance among electronic manufacturing's operators. PARTICIPANTS: Subjects consisted of 36 female operators who were randomly assigned as the experimental (n = 19), and control group (n = 17). METHOD: The experimental participants received five session of weekly HRV biofeedback training of 30-50 minutes each. Physiological stress profiles and cognitive performance were assessed at pre and post-intervention. RESULTS: Significant group x time effects were observed for attention and memory (p < 0.01) but not present for cognitive flexibility. Significant higher total spectrum HRV and low frequency (LF) power also occurred during biofeedback sessions, in addition to slower respiration rate. Physiological stress profile showed that the biofeedback participants were able to increase their LF activity at baseline, stressor, and recovery periods from pre to post. CONCLUSION: This study demonstrates potential application of HRV biofeedback for operator's performance enhancement, associated with increases in HRV.

Introduction: Marital satisfaction is vital to the wellbeing and functioning of the individual and family. Marital dissatisfaction can lead to detrimental effects on mental, physical and family health. The study aimed to determine the proportion of marital dissatisfaction in outpatient setting and its association with sexual functioning and psychiatric morbidity in Kuala Lumpur, Malaysia. Materials & Methods: A crosssectional study was conducted in selected primary care using purposive sampling. Data collection was done using socio-demographic questionnaire and several validated Malay version of self-administered questionnaires. Marital satisfaction was measured by the Malay version of Golombok–Rust Inventory of Marital State (Mal-GRIMS). Results: The prevalence of marriage dissatisfaction in sample population was about 37.3% with almost equal prevalence in both, 36.5% (male) and 37.8% (female). Using a regression analysis, the significant factors that affect marital dissatisfaction were respondent’s age group between 31- 40 years old (Adjusted Odds Ratio, AOR. =11.4, 95% Confidence Interval, CI. =1.2-110.9), spouse’s salary of RM1000-RM2000 (lower income category) (AOR=7.3, 95% CI= 1.9-28.1), anxiety case (AOR= 4.8, 95% CI=1.1- 21.5), depression case (AOR= 4.8, 95% CI=1.0-22.8), female sexual dysfunction in term of arousal function (AOR= 0.01, 95% CI=0.0-0.7), satisfaction dysfunction (AOR= 9.4, 95% CI= 1.5-58) and pain function (AOR=43.7, 95% CI=1.28 - 1489.2). Conclusion: Marital dissatisfaction can be influenced by financial factor, sexual dysfunction and presence of psychiatric morbidity. Hence, in management of marital discord, thorough screening of these factors should be prioritized in clinical setting.

Introduction: Poor understanding and knowledge about thalassaemia has been associated with a poor attitude towards the disease as a whole. Thus, it is the aim of this study to explore the poor attitude and misconceptions about thalassaemia among the parents of thalassaemic patients. Methods: This study was conducted over a six-month period. Five focus group sessions (5-6 per group) involving different sets of parents of thalassaemia patients attending the Paediatric Clinic of Tengku Ampuan Afzan Hospital, Kuantan, Pahang, Malaysia was carried out. Results: The study reveals that misconceptions associated with thalassaemia are still prevalent as shown in our study. Misconceptions that we encountered were related to the underlying cause, sign and symptoms, blood transfusion therapy and iron chelation therapy. Such incorrect knowledge was observed among parents coming from different educational backgrounds and socioeconomic status. As a result of misconceptions parents opt for alternative medicine or to seek treatment from traditional healers for thalassaemia. Conclusions: Several misconceptions still continue despite the nationwide campaign on screening programme to increase awareness about the disease. More effort is needed to improve the knowledge of the parents of thalassaemic patients as they have direct influence on the supervision of the management of thalassaemia patients.
