    Suicide is an important public health problem for adolescents, and it is essential to increase our knowledge concerning the etiology of suicide among adolescent students. Therefore, this study was designed to examine the associations between hopelessness, depression, spirituality, and suicidal behavior, and to examine spirituality as a moderator between hopelessness, depression, and suicidal behavior among 1376 Malaysian adolescent students. The participants completed measures of depression, hopelessness, daily spiritual experience, and suicidal behavior. Structural equation modeling indicated that adolescent students high in hopelessness and depression, but also high in spirituality, had less suicidal behavior than others. These findings reinforce the importance of spirituality as a protective factor against hopelessness, depression, and suicidal behavior among Malaysian adolescent students.

    Suicide is a substantial public health problem, and it remains a serious cause of death in the world. Therefore, this study was designed to examine the relationships between brooding, reflection, emotional intelligence (assessed by performance-based test), and suicidal ideation; the mediation role of emotional intelligence on the relationships between brooding and reflection with suicidal ideation; and the moderating role of suicidal history on the relationships between brooding, reflection, and emotional intelligence with suicidal ideation among Iranian depressed adolescents. The study consisted of a cross-sectional sample of 202 depressed adolescent inpatients from five public hospitals in Tehran, Iran completed measures of depression, rumination, emotional intelligence, and suicide attempt history as indices of suicidal ideation. Structural Equation Modelling estimated that depressed adolescent inpatients with high levels of brooding and reflective rumination, and low levels of emotional intelligence were more likely to report suicidal ideation. Moreover, emotional intelligence partially mediated the relationships between brooding and reflective rumination with suicidal ideation. Suicidal history moderated the relationships between brooding, reflection, and emotional intelligence with suicidal ideation. These findings reinforce the importance of emotional intelligence as an influencing factor against the deleterious effects of rumination styles and suicidal ideation. The results indicate that brooding and reflection have detrimental effects on suicidal ideation in depressed inpatients.

    The main aim of the study was to investigate the effectiveness of two psychotherapeutic approaches, cognitive behavioral therapy (CBT) and a complementary medicine method Reiki, in reducing depression scores in adolescents. We recruited 188 adolescent patients who were 12-17 years old. Participants were randomly assigned to CBT, Reiki or wait-list. Depression scores were assessed before and after the 12 week interventions or wait-list. CBT showed a significantly greater decrease in Child Depression Inventory (CDI) scores across treatment than both Reiki (p

    Nursing is a stressful occupation, even when compared with other health professions; therefore, it is necessary to advance our knowledge about the protective factors that can help reduce stress among nurses. The present study sought to investigate the associations among problem-solving skills and hardiness with perceived stress in nurses. The participants, 252 nurses from six private hospitals in Tehran, completed the Personal Views Survey, the Perceived Stress Scale, and the Problem-Solving Inventory. Structural Equation Modeling (SEM) was used to analyse the data and answer the research hypotheses. As expected, greater hardiness was associated with low levels of perceived stress, and nurses low in perceived stress were more likely to be considered approachable, have a style that relied on their own sense of internal personal control, and demonstrate effective problem-solving confidence. These findings reinforce the importance of hardiness and problem-solving skills as protective factors against perceived stress among nurses, and could be important in training future nurses so that hardiness ability and problem-solving skills can be imparted, allowing nurses to have more ability to control their perceived stress.

    Objective: To investigate attitudes and practices toward smoking among university students and to identify associated factors. Methods: A cross-sectional study was conducted among 1,299 students from five public universities in Thailand. Factor analysis and multiple regression were used for analysis. Results: A higher score of anti-smoking attitude was associated with female gender, majoring in science, living on campus, having a father with primary or secondary school, and those whose father was employed in the private sector. A more positive perceptions about smoking was associated with male gender, having a family income of 30,001-50,000 baht, and having a smoking friend. High positive preventive practice score was associated with those who came from rural areas, having a mother who was self-employed, and having a smoking family member. Conclusions: Although students showed strong anti-smoking attitudes, their preventive practices were poor. These findings should be taken into consideration when developing preventive smoking programs.

    This study presents an investigation on the effect of shield placement for mitigation of transient voltage in a 33/11 kV, 30 MVA transformer due to Standard Switching Impulse (SSI) and Oscillating Switching Impulse (OSI) surges. Generally, the winding and insulation in transformers could experience severe voltage stress due to the external impulses i.e. switching events. Hence, it is important to examine the voltage stress and identify the mitigation action i.e. shield placements in order to reduce the adverse effect to the transformer windings. First, the resistances, inductances, and capacitances (RLC) were calculated for disc type transformer in order to develop the winding RLC equivalent circuit. The SSI and OSI transient voltage waveforms were applied to the High Voltage (HV) winding whereby the transient voltages were simulated for each disc. The resulting voltage stresses were mitigated through different configurations of electrostatic shield placements. The resonant oscillations generated due to switching surges were analysed through initial voltage distribution. The analyses on the transient voltages of the transformer winding and standard error of the slope (SEb) reveal that the location of shield placement has a significant effect on the resonant switching voltages. The increment of the shield number in the windings does not guarantee optimize mitigation of the resonant switching transient voltages. It is found that the voltage stress along the windings is linear once a floating shield is placed between the HV and Low Voltage (LV) windings of the disc-type transformer under the SSI and OSI waveforms. These findings could assist the manufacturers with appropriate technical basis for mitigation of the transformer winding against the external transient switching overvoltage surges.

    This paper proposes an alternative approach to extract transformer's winding parameters of resistance (R), inductance (L), capacitance (C) and conductance (G) based on Finite Element Method (FEM). The capacitance and conductance were computed based on Fast Multiple Method (FMM) and Method of Moment (MoM) through quasi-electrostatics approach. The AC resistances and inductances were computed based on MoM through quasi-magnetostatics approach. Maxwell's equations were used to compute the DC resistances and inductances. Based on the FEM computed parameters, the frequency response of the winding was obtained through the Bode plot function. The simulated frequency response by FEM model was compared with the simulated frequency response based on the Multi-conductor Transmission Line (MTL) model and the measured frequency response of a 33/11 kV, 30 MVA transformer. The statistical indices such as Root Mean Square Error (RMSE) and Absolute Sum of Logarithmic Error (ASLE) were used to analyze the performance of the proposed FEM model. It is found that the simulated frequency response by FEM model is quite close to measured frequency response at low and mid frequency regions as compared to simulated frequency response by MTL model based on RMSE and ASLE analysis.

    To encourage recycling in Malaysian households, a waste separation at source programme was implemented that made it mandatory for households to sort their waste into different categories before leaving it out for collection. Penalties designed to act as a deterrent are imposed on households that fail to sort their waste appropriately. But does this deterrence motivate compliance with the programme directives? This study employs the deterrence theory to investigate if deterrence alone is sufficient to motivate households to actively participate in recycling. A total of 866 questionnaires were administered in person in households in Putrajaya and Melaka. Data were analysed using structural equation modelling. The results of the structural model reveal that just 25% of the variance in compliance is explained by the severity of the sanction, and the perceived certainty of penalty imposed. Perceived severity of sanction (β = 0.149, p = 0.012) and perceived certainty of sanction (β = 0.383, p = 0.000) were found to contribute significantly to compliance behaviour to the programme directives. However, deterrence alone cannot motivate household participation in waste separation at source because it only explains 25% of compliance behaviour. The present study provides information that could allow policymakers to understand recycling habits better and implement more effective compliance strategies.

    Mechanical strength, thermal conductivity and electrical breakdown of polypropylene/lignin/kenaf core fiber (PP/L/KCF) composite were studied. PP/L, PP/KCF and PP/L/KCF composites with different fiber and lignin loading was prepared using a compounding process. Pure PP was served as control. The results revealed that tensile and flexural properties of the PP/L/KCF was retained after addition of lignin and kenaf core fibers. Thermal stability of the PP composites improved compared to pure PP polymer. As for thermal conductivity, no significant difference was observed between PP composites and pure PP. However, PP/L/KCF composite has higher thermal diffusivity. All the PP composites produced are good insulating materials that are suitable for building. All PP composites passed withstand voltage test in air and oil state as stipulated in IEC 60641-3 except PP/L in oil state. SEM micrograph showed that better interaction and adhesion between polymer matrix, lignin and kenaf core fibers was observed and reflected on the better tensile strength recorded in PP/L/KCF composite. This study has successfully filled the gap of knowledge on using lignin and kenaf fibers as PP insulator composite materials. Therefore, it can be concluded that PP/Lignin/KCF has high potential as an insulating material.

    BACKGROUND: The etiological factors of mood disorders and psychopathologies are understudied. In this paper, we explored whether social psychological strains are related to depression, anxiety, and stress in non-clinical populations.

    METHODS: 6,305 college students (39.3% men; 60.7% women) from six Chinese provincial-level jurisdictions completed a paper-and-pencil survey with Psychological Strain Scales (PSS-40) and Depression, Anxiety, and Stress Scales-21 (DASS-21), both validated in Chinese populations.

    RESULTS: Both PSS-40 and DASS-21 have high internal consistency reliabilities, and are highly correlated with each other. Hence, Chinese college students with greater psychological strains (value, aspiration, deprivation, or coping) have greater depression, anxiety, and stress. These results still held after controlling for relevant socio-demographic variables in the multiple regression models.

    LIMITATIONS: This was a cross-sectional study, and the sample only included several provinces in mainland China, not a representative sample of all of them.

    CONCLUSIONS: Mood disorders and psychopathologies are linked to suicidal thoughts and behaviors. The results of this study extend the Strain Theory of Suicide from explaining the risk factors of suicidality to mood disorders and psychopathologies. Hence, these findings can inform prevention measures among college students, and possibly the general population.

    Background: According to the strain theory of suicide, strains, resulting from conflicting and competing pressures in an individual's life, are hypothesized to precede suicide. But social support is an important factor that can mitigate strains and lessen their input in suicidal behavior. Aims: This study was designed to assess the moderating role of social support in the relation between strain and suicidality. Methods: A sample of 1,051 employees were recruited in Beijing, the capital of China, through an online survey. Moderation analysis was performed using SPSS PROCESS Macro. Social support was measured with the Multidimensional Scale of Perceived Social Support, and strains were assessed with the Psychological Strains Scale. Results: Psychological strains are a good predictor of suicidality, and social support, a basic need for each human being, moderates and decreases the effects of psychological strains on suicidality. Limitations: The cross-sectional survey limited the extent to which conclusions about causal relationships can be drawn. Furthermore, the results may not be generalized to the whole of China because of its diversity. Conclusion: Social support has a tendency to mitigate the effects of psychological strains on suicidality.

    Halal authentication has become essential in the food industry to ensure food is free from any prohibited ingredients according to Islamic law. Diversification of food origin and adulteration issues have raised concerns among Muslim consumers. Therefore, verification of food constituents and their quality is paramount. From conventional methods based on physical and chemical properties, various diagnostic methods have emerged relying on protein or DNA measurements. Protein-based methods that have been used in halal detection including electrophoresis, chromatographic-based methods, molecular spectroscopy and immunoassays. Polymerase chain reaction (PCR) and loop-mediated isothermal amplification (LAMP) are DNA-based techniques that possess better accuracy and sensitivity. Biosensors are miniatured devices that operate by converting biochemical signals into a measurable quantity. CRISPR-Cas is one of the latest novel emerging nucleic acid detection tools in halal food analysis as well as quantification of stable isotopes method for identification of animal species. Within this context, this review provides an overview of the various techniques in halal detection along with their advantages and limitations. The future trend and growth of detection technologies are also discussed in this review.

    BACKGROUND: Suicide is a major global mental health problem among college students. The aim of the current study was to explore the association between the psychological strains of the strain theory of suicide and suicidal behaviors among college students.

    METHODS: Participants comprised 1912 college students (16-28 years old, 47.2% female) from three universities in Jilin Province, China, who completed the self-report assessments of psychological strains (40 items Psychological Strains Scale) and suicidal behaviors (Suicidal Behaviors Questionnaire-Revised). The demographic characteristics included four variables: health status, psychological status, academic status and economic status.

    RESULTS: Approximately 15.0% (286/1912) of participants were classified as having suicide risk, based on the cut-off scores of the SBQ-R. The prevalence of suicidal behaviors among males and females was 11.9% (120/1009) and 18.4% (166/903), respectively. Value strain (OR = 1.075, 95%CI: 1.057-1.094), aspiration strain (OR = 1.082, 95%CI: 1.064-1.101), deprivation strain (OR = 1.073, 95%CI: 1.052-1.093), and coping strain (OR = 1.095, 95%CI: 1.075-1.116) were risk factors for suicidality in college students. Coping strain (OR = 1.050, 95%CI: 1.023-1.077) was still positively associated with suicide risk in multivariate logistic regression. Logistic regression analysis indicated that coping strain had the highest correlation with suicidal behaviors.

    LIMITATIONS: The directionality of the relationships cannot be deduced because this study is cross-sectional.

    CONCLUSION: This study confirms a strong association between psychological strains and suicidal behaviors in college students. Some measures can be taken to reduce psychological strains to mitigate suicide risk among college students. More studies investigating coping strain among college students are warranted.

    BACKGROUND/OBJECTIVE: The United States (US) and China are the two largest economies, but recent and directly comparable studies on suicide-related behaviors in the two countries are lacking. By using the Suicidal Behaviors Questionnaire-Revised (SBQ-R), item-level comparison was performed in assessing self-reported suicide-related behaviors between the US and Chinese undergraduates.

    METHOD: This study involved a total of 3,185 college students aged between 18 to 24 years (1,185 US college students, and 2,000 Chinese students who were randomly selected from a large sample of 11,806 Chinese college students). Participants filled out the 4-item SBQ-R.

    RESULTS: Participants' responses were compared by country and sex. There was a higher overall risk of suicide-related behaviors among US students (24.3%) compared to Chinese students (17.0%). US students also reported higher lifetime attempt, past-year ideation, and lifetime threat. US female college students reported the highest suicide-related behaviors compared to other sub-groups.

    CONCLUSIONS: There is a need to tailor specific interventions to alleviate college students' suicide-related behaviors in the US and China, with a particular focus on US females.
