Abstract

Land Surface Temperature (LST) assessment can explain temperature variation, which may be influenced by factors such as elevation, land cover, and the normalized difference vegetation index (NDVI). In this study, a multiple linear regression model of LST variation was constructed based on data from the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite, relating to the period, 2000-2018. The highest LST variation of nearly 1.3 °C/decade was found in savanna areas while the lowest variation was in the evergreen broadleaf forest and woody savanna, which experienced a decrease of 2.1 °C/decade. The overall mean change of LST was -0.4 °C/decade and the regression model with LST as the dependent variable and elevation, land cover type, and NVDI as independent variables produced an R square of 0.376. The variation in LST was different depending upon the NDVI.

Abstract

Performance presumably improves and develops the quality of an organization’s products and services. This study analyzed some factors that are likely contributing to informal worker performance as the informal sector has distinct characteristics from the formal one because it is a more flexible setting with no hierarchical position nor fixed income which usually drives worker performance. We analyze worker performance at one of the Agro-Fish Markets in Indonesia, located in Lamongan, East Java. The multifactor leadership questionnaire (MLQ) was used for formulating the leadership styles, while motivation was measured using the multidimensional work motivation scale (MMWS), which was based on Self-determination Theory (SDT). Safety culture was measured using a questionnaire based on the safety culture approach. Performance was assessed using the behavioral anchor rating scale (BARS). The research design is causal explanatory. Our study involved 171 workers. We use the binary logistic regression to identify the relationship between leadership style, motivation, and age towards safety culture as well as the relationship between safety culture and age towards worker performance. We found that safety culture and age could impact 40.1% on worker performance. Although motivation directly impacted safety culture, the study found that it had an indirect impact on performance. The agro-fish market's characteristics as an informal sector may explain why the findings differ from research on the formal sector.

Abstract

Land Surface Temperature (LST) is a parameter to estimate the temperature of the Earth’s surface and to detect climate change. Papua New Guinea is a tropical country with rainforests, the greatest proportion of which are located on the island of New Britain. Hectares of rainforests have been logged and deforested because of infrastructure construction. This study aims to investigate the change in land surface temperatures on the island from 2000 to 2019. The temperature data were taken from National Aeronautics and Space Administration (NASA) Terra satellites and were analysed using two statistical models: spatial and temporal. The spatial model used multivariate regression, while the temporal one used autoregression (AR). In this study, a cubic spline fitted curve was employed because this has the advantage of being smoother and providing good visuals. The results show that almost all the sub-regions of New Britain have experienced a significant increase in land surface temperature, with a Z value of 7.97 and a confidence interval (CI) of 0.264 – 0.437. The study only investigated land surface temperature change on New Britain Island using spatial and temporal analysis, so further analysis is needed which takes into account other variables such as vegetation and land cover, or which establishes correlations with other variables such as human health.

Abstract

Information Technology (IT) professionals suffer musculoskeletal problems and injuries more frequently due to their type of work which makes them rely on using computers for a prolonged time. The goal of this study is to analyze the risk factors for work-related musculoskeletal disorders in IT professionals. Amount of 150 IT professionals participated in this study as respondents. The Cornell Musculoskeletal Disorders Questionnaire (CMDQ) was used as a measurement tool in determining musculoskeletal complaints among IT professionals. The independent variables (age, gender, working experience, educational level, number of hours spent at work in front of a computer per day, working hours, and exercise habits) that significantly affected the variance in the dependent variable (musculoskeletal disorders) were evaluated using multiple linear regression analysis (p-value < 0.05). IT professionals reported experiencing symptoms most frequently 3–4 times per week in the upper back (45.3%) and back (31.3%), and once or twice per week in the upper back (33.3%) and back (31.3%). Then on the discomfort level, IT professionals feel very uncomfortable in the back (71.3%), upper back (68.7%), and neck (64%). The number of hours spent at work in front of a computer per day (p-values of 0.040) and working hours (p-value of 0,032) are significant predictors of IT professional musculoskeletal disorders. IT professionals reported experiencing the greatest musculoskeletal issues in the right upper extremity, which comprises the right wrist, right forearm, right shoulder, and right upper arm (88%). Back (84%) and left lower extremities (82.7%), which include the left thigh, left knee, and left lower legs, are two other issues that most IT professionals have.

Abstract

Introduction: Major industrial accidents or disasters can have significant impacts on various aspects, including human health, the environment, societal well-being, and national economies. The concept of safety culture is increasingly receiving attention as a means of mitigating industrial mishaps. Nonetheless, a dearth of comprehensive systematic reviews exists that specifically examine the important role of safety culture in effectively mitigating severe industrial accidents across diverse industries on a global scale. Hence, the primary aim of this research is to examine the important role of safety culture in the effective management of industrial accidents across diverse sectors. Method: The systematic literature review (SLR) from the ScienceDirect database was established using the four basic procedures outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A total of thirty-three scholarly publications were retrieved from the database, encompassing the years 2017 to 2021, which specifically address the important role of safety culture in the effective management of major industrial incidents. Results: The findings yielded two primary themes, namely, the significance of safety culture at both the managerial and employee levels. These topics were then categorised into ten subthemes. The findings indicate that safety culture exerts a significant influence at the managerial level in mitigating industrial accidents through the enhancement of safety training. Conclusion: In summary, a safety culture holds significant importance within the realm of management as it serves to effectively mitigate the occurrence of industrial accidents in the years to come.
