The printing industry is diverse and serves all the economic sectors. In the graphic industry it is common to use paints and solvents that have risky chemical substances in their composition which may cause damage to the central nervous system, euphoria, dizziness, drowsiness, irritations in the eyes, in the skin and respiratory tract. This research uses a qualitative chemical risk database from the International Chemical Control Toolkit (ICCT), adapted from COSHH Essentials published in 1998 by Healthy and Safety Executive (HSE), in the United Kingdom. A qualitative methodology, simple and practical, was applied to solvent washing activities of the graphic printing industry of a flexible plastic packaging company in Campina Grande-PB. A qualitative methodology was used to determine preventive actions and control measures for ethyl acetate solvent exposure. From simple information contained in the MSDS of chemical substance, such as safety phrases and boiling temperature, together with the amount handled by the worker and the operating temperature of the activity, it was possible to establish adequate control measures to be implemented in the areas with chemical hazard.

The nervous system remains one of the least understood biological structures due in large part to the enormous complexity of this organ. A theoretical model for the transfer of nerve impulses would be valuable for the analysis of various phenomena in the nervous system, which are difficult to study by experiments. The central nervous system is composed of more than 100 billion neurons, through which information is transmitted via nerve impulses. Nerve impulses are not immediately apparent since each impulse may be blocked during transmission, changed from a single impulse into repetitive impulse, or integrated with impulses from other neurons to form highly intricate patterns. In the human central nervous system, a neuron secretes a chemical substance called a neurotransmitter at the synapse, and this transmitter in turn acts on another neuron to cause excitation, inhibition, or some other modification of its sensitivity.

Combating child labour in Tanzania is a challenging endeavour especially in small-scale gold mining communities. Studies on child labour in Tanzania indicate that the government in partnership with international actors has undertaken several intervention actions to control and eliminate child labour in the country. Yet, child labour continues to be dominant in virtually all economic sectors including small-scale gold mining for reasons not sufficiently known. This research sets out to explore the challenges that face anti-child labour actors in their efforts to control and reduce child labour in Kahama district in Shinyanga region. The study uses a qualitative methodology in order to gain an in-depth insight of the context, cultural realities, community members’ views and experiences relating to child labour in small-scale gold mining communities. A sample size of 38 participants was drawn from among regional and district government officials, non-governmental organization (NGO) workers and community-based organization (CBO) activists responsible for combating child labour, small-scale gold miners, parents and children in Shinyanga region. Data was collected through in-depth interviews, focus group discussions and documents review. Findings revealed seven challenges facing anti-child labour actors in their efforts to combat child labour in small-scale gold mining communities all arising from within the household, local community and government contexts. The study recommends that the government, policy makers and other stakeholders should develop policy interventions that effectively address these challenges in order to eradicate child labour in small-scale gold mining communities in the country. Keywords: Child Labour, Small-Scale Gold Mining, Anti-Child Labour Actors, Challenges.

At the end of December 2019, a pandemic of life-threatening disease known as COVID-19, caused by a virus that is highly infective and capable of damaging the respiratory system of a human body, to eventually causing death within a short span of time, has been reported in Wuhan, China. This virus has spread to hundreds of countries with hundred thousand positive cases of COVID-19, as well as thousands of death recorded until April 2020. Similarly, Malaysia also faces the pandemic of COVID-19 and recorded an increase of positive cases with more than 50 deaths until today. Multiple drastic preventive measures and steps have been implemented by the authorities in Malaysia to prevent the spread of the COVID-19 outbreak. Hence, this study is conducted to identify control measures that have been used globally, by looking into recent literature studies and focusing on the enforcement of Restriction of Movement Order (RMO) measure in Malaysia. In evaluating the legality of the implementation, the concept of siasah syar’iyyah, which is an effective mechanism in safeguarding the public interest or common good as required in Islam, must be taken into consideration. Therefore, qualitative methodology was duly adopted to explore the jurisprudential approach of prior Muslim governments, by analyzing highly regarded principal references that addressed similar cases. The basic principles of Islam, as contained in the Quran and ḥadīth of Rasulullah PBUH, applied in the decision making process and the rationality of actions taken in addressing any pandemic of disease would also be observed through data analysis methodology (content analysis). The approach of Islamic jurispru-dence methodology that is relevant and its application to this issue is also very important to be elaborated to understand that the process used before arriving at each decision by the authorities should adhere to the concept of maqāṣid and main principles of sharī‘ah. The result of the study found that the preventive measures to control the pandemic outbreak currently implemented by Malaysian government as well as the policies being enforced in dealing with the life-threatening pandemic is consistent with the injunctions of Islamic law that should be obeyed by all parties. Abstrak Pada akhir Disember 2019, pandemik penyakit yang mengancam nyawa manusia dikenali sebagai COVID-19, sejenis virus yang mudah dijangkiti, mampu merosakkan sistem respiratori tubuh manusia seterusnya menyebabkan kematian dalam jangka masa pendek telah dilaporkan berlaku di Wuhan, China. Virus ini telah merebak ke ratusan buah negara dengan  ratusan ribu kes positif COVID-19 beserta ribuan kematian telah dicatatkan sehingga April 2020. Malaysia turut  berdepan dengan wabak COVID-19 dan merekodkan peningkatan kes positif dengan lebih 50 kematian setakat  hari ini. Pelbagai langkah dan kaedah kawalan drastik telah dilaksanakan oleh badan berautoriti di Malaysia untuk mengawal penularan wabak COVID-19. Justeru kajian ini dibuat  untuk mengenalpasti kaedah-kaedah pengawalan yang dilaksanakan di peringkat global dengan melihat kajian-kajian literatur terkini dengan penumpuan kepada penguatkuasaan kaedah Perintah Kawalan Pergerakan (PKP) di Malaysia. Dalam menilai kesahan pelaksanaan, konsep siasah syar’iyyah yang merupakan satu mekanisme efektif dalam menjaga kemaslahatan awam seperti yang dituntut oleh Islam harus diambilkira. Oleh yang demikian, metod kualitatif digunapakai untuk meneroka pendekatan ijtihad kerajaan Islam terdahulu dengan menganalisis kitab-kitab muktabar dalam menangani beberapa kes yang sama. Prinsip-prinsip asas Islam yang terkandung dalam al-Quran dan sunah Rasululullah SAW dalam proses membuat keputusan dan kewajaran tindakan yang perlu diambil dalam menangani suatu wabak penyakit akan turut diteliti melalui kaedah analisis data (content analysis). Pendekatan kaedah-kaedah memastikan yang relevan serta pengaplikasiannya dalam isu ini juga sangat penting untuk diperhalusi bagi memahami bahawa proses setiap keputusan yang diambil tindakan oleh badan berautoriti perlu menepati konsep maqasid dan prinsip utama syariah. Hasil kajian mendapati, kaedah kawalan penularan wabak yang sedang dijalankan oleh kerajaan Malaysia berserta dasar dan polisi yang dikuat kuasakan dalam menangani pandemik yang mengancam nyawa masyarakat adalah bertepatan dengan perintah syarak yang wajib dipatuhi oleh semua pihak.

Background: Japanese enchepalitis (JE) is a viral disease that considered as zoonotic disease, which transmitted through mosquito vectors that had JE virus. Mainly caused by the mosquito C. Tritaeniorhynchus (the most important vector is the mosquito Culex, which feeds on cattle in preference to human). JE virus disease can also cause disturbances in the central nervous system eg. brain, bone marrow, and meninges which has serious impact on public health. This disease has been reported from Japan, Korea, Taiwan, India, Myanmar, Thailand, Western Pacific and Southeast Asia to Indonesia. However, the incidence of this disease in Indonesia has not been well known in various animal species or humans. Aim: The purpose of this study is to develop rapid diagnostic examinations on patient diagnosed JE virus in Surabaya by using PCR (Polymerase Chain Reaction). Because, JE disease can lead to dead-end at the patient if not treated immediately. Method: The research methods, extraction method, PCR (1st RT-PCR and 2nd Nested PCR) are conducted using Japanese encephalitis PCR detection kit. Result: The results of the examination showed that 2 out of 17 people (11,765%) are positive with PCR bands 227 bp (basepair). This diagnostic technique to determine and to deal with early onset of the disease. Solutions for preventive actions can be started from the termination of the cycle vectors to vaccination measures. Conclusion: For his own medical factors given to reduce fever and swelling and reduce the pain.

The main aim of this paper is to establish that essential aspects are determinant in the enterprise risk identification (ERI) and the existing interrelationship between each corporate risk goals, in the large companies of Colombia. Study proposes a parametric analysis and a non-parametric. The first uses correlation matrices for statistical analysis, a multiple linear regression statistical tools to identify that essential aspects are determinant in the (ERI). The second proposes a new aggregation called the Bonferroni Induced Ordered Weighted Average Adequacy Coefficient (BON-IHOWAAC) operator and Bonferroni Induced Ordered Weighted Average the Maximum and Minimum level (BON-IHOWAIMAM) to establish the existing interrelationship between each corporate risk goals using the risk management information and manager perception. Of the results obtained is highlighted that for all economic sectors; first, control measures are highlighted in the (ERI) and second, the goal with the greatest interrelationship for the other ones to be achieved is protect people. Finally, the study concludes with a holistic analysis of the importance that executive team gives to the management of risks from the prioritization of objectives and the use of tools for the treatment of information to improve the process of decisions-making in uncertain contexts.

Abstract Microplastics (plastic particles < 5 mm) is a pollution of growing concern. Microplastic pollution is a complex issue that requires systematic attempts to provide an overview and avoid management solutions that have marginal effects or only move the pollution problem. Substance flow analysis (SFA) has been proposed as a useful tool to receive such an overview and has been put forward as valuable for substance management. However, as the research on microplastics has only emerged recently, detailed and reliable SFAs are difficult to perform. In this study, we use three SFA studies for three pollutants (cadmium, copper and pharmaceuticals) to compare flows and strategies to control the flows. This in order to seek guidance for microplastic management and evaluate potential strategies for controlling microplastics. The analysis shows that there has been rigorous control on different levels to abate pollution from cadmium, copper and pharmaceuticals, but where in the system the major control measures have been carried out differ. For microplastics, there are many potential solutions, both in terms of preventive actions and treatment depending on the type of source. When forming management plans for microplastics, the responsibility for each measure and the impact on the whole urban system should be taken into consideration as well as which receiving compartments are particularly valuable and should be avoided.

Background: With the insurgence of the COVID-19 pandemic, many people died in the past several months, and the situation is ongoing with increasing health, social, and economic panic and vulnerability. As most of the countries relying on different preventive actions to control the outcomes of COVID-19, it is necessary to boost the knowledge about the effectiveness of such actions so that the policymakers take their country-based appropriate actions. This study generates evidence of taking the most impactful actions to combat COVID-19. Objective: In order to generate community-based scientific evidence, this study analyzed the outcome of COVID-19 in response to different control measures, healthcare facilities, life expectancy, and prevalent diseases. Methods: It used more than a hundred countries’ data collected from different databases. We performed a comparative graphical analysis with non-linear correlation estimation using R. Results: The reduction of COVID-19 cases is strongly correlated with the earliness of preventive initiation. The apathy of taking nationwide immediate precaution measures has been identified as one of the critical reasons to make the circumstances worse. There is significant non-linear relationship between COVID-19 case fatality and number of physicians (NCC = 0.22; p-value ≤ 0.001), nurses and midwives (NCC = 0.17; p-value ≤ 0.001), hospital beds (NCC = 0.20; p-value ≤ 0.001), life expectancy of both sexes (NCC = 0.22; p-value ≤ 0.001), life expectancy of female (NCC = 0.27; p-value ≤ 0.001), and life expectancy of male (NCC = 0.19; p-value ≤ 0.001). COVID-19 deaths were found to be reduced with increased medical personnel and hospital beds. Interestingly, no association between the comorbidities and severity of COVID-19 was found excluding asthma, cancer, Alzheimer’s, and smoking. Conclusions: Enhancing healthcare facilities and early imposing the control measures could be valuable to prevent the COVID-19 pandemic. No association between COVID-19 and other comorbidities warranted further investigation at the pathobiological level.


Human factors is an important aspect to consider when designing a safe and healthy workplace. Human errors are usually outcomes of long chains of events, and preventing human error at work calls for preventive actions or safety–related measures that include the human factors in order for it to be effective. Human factors are addressed with regard to safety and health with the goal to optimise human performance and minimise human failures. Accident causation is a very complex phenomenon and need to be understood adequately with the purpose of improving workplace safety. Based on the Swiss Cheese Theory, human error is studied in this paper. Objectives: To study how human errors are involved in safety–related accidents at the workplace; and to study how human factors can be integrate in accident prevention. Methodology: A qualitative study using document analysis method. Results and discussion: Conclusion: workers’ individual attributes may also be the source of accidents. People tend to make a lower risk estimation of their own job compare with other jobs; and underestimated the risks within their own job. The availability of information relevant to the hazard, risk estimations, types of exposure, and control measures are useful in helping people to understand risks better.

Background: Neurocysticercosis is a globally occurring parasitosis that affects the central nervous system. The main clinical manifestation is seizures.The aim of this study was to analyze the geographic distribution of patients with seizures attending the Emergency Unit of the Piedade municipality, SP, with a diagnosis of neurocysticercosis, and to compare the association of its prevalence with age, basic sanitation and food hygiene habits between rural and urban areas. Methods: One hundred thirty-six patients with seizures were evaluated. The Epidemiological data of all subjects will be described. Results: The diagnosis of neurocysticercosis was confirmed in 24 patients, corresponding to a prevalence of 17.65%. The presence of an open sewer predominated in the rural area, while the consumption of unwashed fruits, presence of elderly people and geographic distribution were similar in the two areas. Conclusions: Urgent measures to raise awareness about the disease and preventive actions should be taken by world authorities.
