Safety boots

Nowadays, safety boots are necessary and essential to workers in order to avoid harm and injury at a workplace. Safety boots can be defined as a personal protective equipment (PPE) for foot protection at workplace from getting foot injuries caused by sharp object, hot object, splinters, and corrosive from chemical. Safety boots are further divided into 2 style which is formal and informal. The use of safety boots is mandatory in a work environment such as: • Handling hard and heavy object • Involve in handling round object that may dropped at your feet • Workplaces that are hazardous • Work that involved sharp object • Working with electric cable • Work on a floor with static electricit

Influence of Overweight, Obesity, Social Support, and Self-Efficacy on Breastfeeding Outcomes Among African-American Women

Breastfeeding reduces morbidity and mortality among mothers and children, yet African-American women breastfeed at lower rates than women of other racial and ethnic groups do. Higher rates of overweight, obesity, and low socioeconomic status may be contributing factors in this population; however, limited research exists regarding the roles of maternal overweight and obesity on breastfeeding outcomes. The purpose of this study was to examine whether social support and self-efficacy positively influence breastfeeding outcomes among overweight and obese African American women. Self-efficacy and social support theories provided the theoretical framework for the study. Research questions examined whether (a) maternal overweight and obesity, social support, and self-efficacy were associated with breastfeeding initiation and duration among African-American women; and (b) self-efficacy mediated this association. The study design was a quantitative retrospective analysis of a subset of secondary data from the 2009-2011 Pregnancy Risk Assessment Monitoring System (n = 10,926). SPSS 21.0-® was used for analyses. Obesity was significantly associated with breastfeeding durations of 9-16 weeks and 17 or more weeks. Self-efficacy was significantly associated with breastfeeding initiation only. Social support was negatively associated with breastfeeding durations of 9-16 weeks among obese women. Positive social change implications include increased knowledge of the associations between overweight, obesity, social support, self-efficacy, and breastfeeding outcomes among African-American women. This knowledge could be used to inform the development of interventions to improve breastfeeding and weight related health outcomes

Patterned resistive sheets for potential use in 3D stacked multispectral reduced thermal mass microbolometer

textPatterned resistive sheets (PRS) are resistive sheets with periodic patterns which provide further advantages to the functionality of the microbolometer. This study examines the potential of both single- and double-layer designs to achieve spectral selectivity in both broadband and narrowband absorption in the microbolometer's application. First, important design parameters, including rules and processes, are established. These include descriptions of sheet resistance, air gap, material refractive index, thicknesses of dielectric and bolometric layers, mirror, pattern shape and size, and unit cell period. Moreover, interactions among these elements are examined. Second, single-layer designs using dipole and slot PRS are introduced as initial designs for the reduced thermal mass design. Applying holes without changing spectral selectivity are investigated for narrowband application. Moreover, the method to tune the change of spectral selectivity is introduced. Third, newly stacked two-color design is suggested. The out-of-band transmission and reflection characteristics of the dipole and slot PRS are investigated to increase the absorption of each layer. Additionally, different pattern shapes, such as the circular patch and square patch, are investigated for easier fabrication.Electrical and Computer Engineerin

Computer-based Student Information System in USM

Memandangkan kesan sistem maklum~t berkomputer ke atas keberkesanan organisasi agak sukar diukur, kegunaan konstruk kepuasan maklumat pengguna merupakan asas yang paling ketara di dalam penilaian k~berkesanan sesuat~ sistem maklumat. Kajian ini memilih suatu ukuran yang diperakui untuk manilai kepuasan maklumat dengan sistem Maklumat Berkomputer Pelajar pengguna (SMP) di Universiti Sairis Malaysia. Dengan menyesuaikan soal selidik yang dip~rkenalkan oleh Bailey dan Pear~on (1983), suatu versi soal selidik yang terubahsuai disediakan dan dirintiskan secara percubaan. As the impactot c~mputer based information system on organizational effectiveness is difficult tomeasure~ the user information satisfaction construct has occupied a dominant role in the assessment of information system effectiveness. This study selects a validated instrument to measure user information satisfaction with Universiti Sains Malaysia's computer based student, information system (Sistem Maklumat Pelajar (SMP)). Adapting Bailey and Pearson's (1983) original instrum~ nt, a modified version of the questionnaire was devel- I oped and pilot te~ted

Goal Orientations, Mathematics Self-Efficacy and Cognitive Strategies as Predictors of Students' Mathematics Achievement

The purpose of this study is to examine the relationship between students' goal orientations (learning and performance), mathematics self-efficacy, cognitive strategies (deep and shallow) and mathematics achievement. This study also attempts to identify the predictors of deep cognitive strategy, shallow cognitive strategy and mathematics achievement. The sample consisted of 339 Form Four students. Pearson correlation showed that learning goal and mathematics self-efficacy were significantly correlated with each other (r = 0.57, p< .01). Deep cognitive strategy was significantly (p< .01) correlated with learning goal (r = 0.49) and mathematics self-efficacy (r = 0.54). The relationship between these three variables was positive and of moderate strength. Performance goal was positively correlated with shallow cognitive strategy (r = 0.18, p< .01), but the relationship was slight. Mathematics achievement was significantly (p< .01) correlated with learning goal (r = 0.22), mathematics self-efficacy (r = 0.30) and deep cognitive strategy (r = 0.20). In contrast, mathematics achievement was negatively correlated with performance goal (r = -0.16, p< .01) and shallow cognitive strategy (r = -0.11, p< .05), but the correlations for all these were considered weak. Stepwise multiple regression analyses were utilized to identify the predictors of deep cognitive strategy, shallow cognitive strategy and mathematics achievement. Results showed that mathematics self-efficacy and learning goal were significant predictors of deep cognitive strategy. Both learning goal and performance goal were significant predictors of shallow cognitive strategy. Mathematics self-efficacy, performance goal and shallow cognitive strategy served as significant predictors of students' mathematics achievement
