Published: August 2021

Background Drug abuse is one of the world's most serious and rapidly rising problems, causing a wide variety of health issues with significant morbidity and mortality. This study aimed to explore the association between part-time work and substance abuse among vocational students. Design and methods We conducted a cross-sectional analytical study that included all part-time working male students from five vocational male schools, and we used a standardized pretested questionnaire after obtaining written informed consent. A One- Step Multi-Drug Screen Test was used to assess the substances that were abused Results A total of 316 out of the 400 invited students participated in our study. Of the total screened subjects, 26.6 % were abusing substances. Twenty-five (36.2%) day working adolescents, nine (14.0%) night working adolescents, and forty (36.0%) day and night working adolescents were abusers. Tobacco was the most widely abused drug (68%) in the form of smoking, followed by cannabis (24%), marijuana (16.4%), alcohol (10%), and opioid (6.3%). Night workers had significantly lower rates of smoking, cannabis, Marijuana, alcohol, or opioids abuse, and Logistic regression was performed to ascertain the effects of the work schedule on the likelihood that participants have substance abuse; Night workers were 7.14 times less likely to have substance abuse than day workers, while day and night work did not differ from day work. Conclusions The prevalence of drug abuse in vocational students is considered high and a serious problem that damages the youth and the community.

Published: August 2021

Background Single-use personal protective equipment (PPE) has been essential to protect healthcare workers during the COVID-19 pandemic. However, intensified use of PPE could counteract the previous efforts made by the UK NHS Trusts to reduce their plastic footprint. Design and methods In this study, we conducted an in-depth case study in the Royal Cornwall Hospitals NHS Trust to investigate plastic-related issues in a typical NHS Trust before, during and after the pandemic. We first collected hospital routine data on both procurement and usage of single-use PPE (including face masks, aprons, and gowns) for the time period between April 2019 and August 2020. We then interviewed 12 hospital staff across a wide remit, from senior managers to consultants, nurses and catering staff, to gather qualitative evidence on the overall impact of COVID-19 on the Trust regarding plastic use. Results We found that although COVID-19 had increased the procurement and the use of single-use plastic substantially during the pandemic, it did not appear to have changed the focus of the hospital on implementing measures to reduce single-use plastic in the long term. We then discussed the barriers and opportunities to tackle plastic issues within the NHS in the post-COVID world, for example, a circular healthcare model. Conclusion Investment is needed in technologies and processes that can recycle and reuse a wider range of single-use plastics, and innovate sustainable alternatives to replace singleuse consumables used in the NHS to construct a fully operational closed material loop healthcare system.

Published: August 2021

This paper presents an empirical study on women’s financial literacy in a developing country, Indonesia. Financial literacy in developing countries, especially for women, needs to be improved. Traditionally, women have an important role in managing family finances. Their ability to conduct good financial management can help their family’s financial stability and improve its welfare. If women do not have adequate capacity to manage the family’s finances, the family’s economic health can be at risk. Having financial literacy is important as it provides financial resilience at times of uncertainty. This explanatory research uses a sample comprising 100 women living in the city of Bandung, Indonesia, who are in the Baby Boomer generation as well as in Generations X, Y, and Z. The data were collected through an online questionnaire and analyzed using partial least squares structural equation modeling (PLS-SEM). The results provide evidence that perceived financial knowledge has a significant effect on financial management behavior in the dimensions of savings behavior, shopping behavior, long-term planning, and short-term planning. Moreover, the study results show that the respondents have a moderate level of financial literacy and financial management behavior.

Published: August 2021

Poor nutritional status, especially during childhood, has a negative impact on one’s early life as well as throughout their life. One of the factors that influences the improvement of children’s nutritional status is the bargaining power of the mother. Previous studies have limitations in that they often use cross-sectional data and indirect approaches to measuring bargaining power. This study aims to measure the impact of maternal bargaining power on children’s nutritional status in Indonesia. The unit of analysis is children aged 7–19 years (IFLS5) who still have and live with their parents (IFLS4). Using the OLS estimation method, the results show that maternal bargaining power significantly and positively influences the nutritional status of children (HA z-score).

Published: August 2021

All countries affected by the COVID-19 pandemic have established several policies to control the spread of the disease. The government of Indonesia has enforced a work-from-home policy and large-scale social restrictions in most regions that result in the changes in community mobility in various categories of places. This study aims to (1) investigate the impact of large-scale restrictions on provincial-level mobility in Indonesia, (2) categorize provinces based on mobility patterns, and (3) investigate regional socio-economic characteristics that may lead to different mobility patterns. This study utilized Provincial-level Google Mobility Index, Flight data scraped from daily web, and regional characteristics (e.g., poverty rate, percentages of informal workers). A Dynamic Time Warping method was employed to investigate the clusters of mobility. The study shows an intense trade-off of mobility pattern between residential areas and public areas. In general, during the first 2.5 months of the pandemic, people had reduced their activities in public areas and preferred to stay at home. Meanwhile, provinces have different mobility patterns from each other during the period of the large-scale restrictions. The differences in mobility are mainly led by the percentage of formal workers in each region.
Does Uncertainty Matter for Trade - Economic Growth Nexus in Indonesia?
Authors: Febiyansah Panky Tri , Cahyono Bintang Dwitya , Novandra Rio 
Published: August 2021

This paper aims to test the impact of uncertainty on the causal relationship among exports, imports, and economic growth in Indonesia. The relationship is constructed by examining the presence of FDI-adjusted exports and imports (trade) and the output link using conditional variances-covariances derived from the generalized autoregressive conditional heteroskedastic (GARCH) process in a vector error correction model (VEC-GARCH model). Using evidence in Indonesia, the model exposes the uni-directional nexus from trade performance to trade-adjusted output growth in the absence of uncertainty. The volatility effects are evident in the causal relationship between trade and output. The finding shows that the uncertainty effects hamper the trade-economic growth nexus. Incorporated with the long-run causality, trade still causes output even after containing the contributions of volatility. The significant role of imports highlights the higher demand for intermediate capital products and the inclusion of technology in strengthening economic growth.

LEAN MANUFACTURING PRACTICES AND SUPPLY CHAIN PERFORMANCE OF SUGAR MANUFACTURING FIRMS IN WESTERN KENYA
Authors: Ochieng Bob 
Published: August 2021

Introduction: Western Kenya is the largest producer of sugar in Kenya, supporting about 170,000 smallholder farming households and contributing about 80 percent of the total sugar produced in Kenya. This contribution is however threatened given that the sugar firms in that region are producing sub optimally with obsolete technology. Comparing to related sector, other firms in Kenya such as the tea manufacturing firms have implemented energy efficiency practices so as to manage energy wastage and reduce production costs. Were they to employ effective production methods, they could increase their production significantly. While that is the case, scholars have suggested that adoption of lean manufacturing practices is a panacea to quality addition and waste minimization. Perhaps what these firms need are lean practices.
Purpose: This study interrogated the extent to which the firms have adopted lean manufacturing practices, just-in-time and total quality control and if they have, its effect on supply chain performance.
Methodology: The study targeted and conducted a census on the 11 sugar manufacturing firms in the Western Kenya belt where the procurement managers, line managers, finance managers, production managers, production engineers, quality assurance officers and operations managers of each of the 11 firms (total 87) were targeted. The study employed a descriptive research design to collect quantitative data. Quantitative primary data was collected through questionnaires and analyzed using statistical package for social sciences.
Findings: The findings of the study indicated that the just in time productionand total quality control are positively and significantly associated with supply chain performance of the sugar manufacturing firms.
Unique Contribution to Practice and Policy: The study recommended adoption of just in time production practices such as availing labor on demand in order to manage labor costs, availing resources on demand in order to manage wastage, production on demand in order to manage inventory costs, ordering raw materials from the suppliers only when there is demand for production from customers, having a simplified production design to ensure timely production and having multiple skilled workers to ensure faster production. In addition, in order for the sugar manufacturing firms to increase supply chain performance, there is need to adopt total quality control practices such as having manageable defect prevention costs related to quality planning, putting in place manageable defect prevention costs related to investment in quality related information systems, having manageable appraisal costs related to test and inspection of purchased materials, having manageable appraisal costs related to quality audits, having controllable internal failure costs related to reworks and having manageable internal failure costs related to scrap.

Published: August 2021

Electrodeposition an advanced thin film deposition method originally used for decorative purposes and now widely used in industrial applications such as electronics, phonics, magnetic recording and protective coatings, has also been used for the production of size and structure-controlled nanoparticles. In this research, the electrodeposition of silver (Ag) films on gold (Au) substrates with two plant (Ocimum gratissimum (Og) and Vernonia amygdalina (Va) leaf extracts as additives was explored . The effect of these leaf extracts immediately after addition and after a prolonged exposure in the electrolyte on the silver deposits was studied using cyclic voltammetry (CV), chronoamperometry (CA) and linear sweep voltammetry (LSV). Silver thin films were electrodeposited on gold film from an electrolyte of 5 mM AgNO3 and later 5 mM AgNO3 +0.1 M KNO3 for 10 minutes, using a double potential step protocol and potentials -0.15 V and -0.3 V with and without the plant leaf extracts. As silver was grown on the gold substrate, silver nanoparticles were also discovered to have been formed in the electrolyte. Though the deposition potential in the presence of the plant leaf extracts affected the kinetics of the silver deposition on the gold substrate, it only slightly affected the silver film thickness on the gold. CV graphs with the plant leaf extracts show lower current densities indicating a slowing down of the deposition/dissolution rates of silver probably due to the adsorption of the leaf extracts on the surface of the growing silver films which may have affected the transport of silver ions (Ag+) towards the electrode and impacted on the silver deposition/dissolution kinetics. The deposited silver film thickness was 7 nm to 8 nm with the Og leaf extract and 1.5 nm to 2 nm with the Va leaf extract. Atomic Force microscope (AFM) was used for viewing the silver films and the mean grain sizes of the Og silver films was calculated to be . This was larger than those of the Va silver films calculated to be While the Va silver films surface roughness was higher at 10.6 , that of the Og silver film was 9.3.
Simulation of an Industrial Carbon Black Reactor Using Collision Kinetics
Authors: Igbagara Princewill 
Published: August 2021

Purpose: Objective of the work was to test efficacy of the proposed flame chemistry and collision kinetics for prediction of process parametres through determination of the effect of basic process parameters on yield (which includes but not limited to grade of carbon black produced).
Methodology: The research methodology in this work was simulation of an industrial Carbon Black Reactor based on reaction kinetics from flame chemistry which assumes that primary particle formation and particle growth is strictly by collision of molecular nuclei with gas molecule as proposed by the collision theory. Decant oil from the Fluid Catalytic Cracking Unit (FCCU) of the Warri Refinery and Petrochemical Company Limited of Nigeria represented by naphthalene was used as feedstock in the simulation while methane gas is the fuel for combustion needed to attain the reaction temperature.
Findings: Results showed an excellent quantitative prediction of trends by models. Qualitative predictions gave far higher parameter values, something easily attributable to the excessively high values of kinetic data used for model testing.
Recommendation: The simplifying assumptions of these models completely ignored microscopic phenomena such as interface mass and heat transfer and other similar processes. Consequently, the model can be improved upon by introducing some of these processes as identified.

A Review of the Robotic Radical Prostatectomy Outcomes
Authors: Maharajh Suhani 
Published: August 2021

ABSTRACTRobotic radical prostatectomy was first performed in 2000. The superior range of movement as well as better ergonomics were clear advantages of this technology. This technology and its cost can however only be justified, if it has clear data confirming its equivalence or preferably superiority in management. Open radical retropubic prostatectomy has previously been the gold standard for oncological outcomes in organ confined prostate cancer. Follow-up data showed good 5-year cancer free survival and mortality and Walsh's technique contributed significantly to improvement of quality of life issues, such as sexual function. In spite of improved survival rates with other less invasive modalities, such as brachytherapy and intensity-modulated radiotherapy, the radical prostatectomy is still a popular treatment choice as there is long-term data to support evidence of durable cancer control. The recovery and cost of the open procedure has often been a disadvantage. Minimal access surgery was able to overcome these issues with good surgical outcomes. Robotic surgery may well be the next step in surgical and technological revolution and has the possibility of making minimally invasive surgery accessible to surgeons with less laparoscopic experience. This review will attempt to assess the outcomes of robotic surgery to determine if it is indeed a feasible option for the treatment of organ confined prostate cancer, by assessing the surgical outcomes.How to cite this articleMaharajh S.
