Boosting Biowaste Valorisation—Do We Need an Accelerated Regional Implementation of the European Law for End-of-Waste?
Authors: Siegfried Konrad , Günther Susann , Mengato Sara , Riedel Fabian , Thrän Daniela
Published: September 2023

The valorisation of municipal and household biowaste as a relevant component of the EU’s Circular Economy Strategy is currently under discussion. However, there are several legal, technical and economic challenges associated with biowaste valorisation. This paper aims to pinpoint factors affecting biowaste supply chains using the PESTEL+I method and stakeholder workshops. Our analysis focuses on the macro-environment of an integrated biowaste conversion and valorisation concept in the region of Wallonia, Belgium. One key influencing factor is the EU’s legal framework on waste, which describes the end-of-waste status and defines criteria for biowaste reuse. While the analysis shows that EU regulations support biowaste valorisation, its transposition into national and regional law is lagging behind. The technological development of biowaste concepts might be hampered and many questions related to the marketisation of bio-based products remain unanswered. We therefore suggest that legal procedures for biowaste management have to be facilitated at the regional level. The region of Wallonia should establish a category for biowaste that would include standardized procedures for biowaste valorisation and products. It is essential that such regional barriers be overcome to establish the necessary cooperation with local stakeholders and to transfer biowaste supply chains to the market.

Authors: Guo Zixun , Gao Zhimei , Zhang Wenbin
Published: September 2023

This study aims to clarify the sectoral level of environmental pollution “rights, responsibilities and benefits” and to identify the sectoral pollution “background” to lay the foundation to achieving sustainable economic development. We use input output table data to account for and decompose the sectoral energy footprint. Firstly, based on the principles of producer responsibility and consumer responsibility, the consumption-based energy footprint (CBEF) and the responsible-based energy footprint (RBEF) are accounted for. Secondly, the sectoral energy footprint is decomposed based on energy consumption and responsibility and direct and indirect perspectives. The results show that (1) the distribution of the sectoral CBEF is characterized by a high sector concentration and large inter-sector differences. (2) The distribution of the sectoral RBEF is more balanced, and the difference is smaller. (3) There are also asymmetries and heterogeneity in trends between the sectoral CBEF and the sectoral RBEF. (4) The energy footprint generated by the production of intermediate-use products is an important source of the sectoral energy footprint (EF). The Chinese government should develop differentiated energy saving and emission reduction measures and optimize the sectoral structure to enhance sectoral cleanliness. Policy references for energy saving and emission reduction at the sectoral level and early achievement of carbon-peak and carbon-neutral targets are proposed.
Sustainable Exploration of “Plug-In Design” in Public Space of the Old City in Guangzhou: Case Study on Xudi-Gaodijie
Authors: Bai Haochen , Li Minzhi , An Zhenfang
Published: September 2023

The current regeneration mode of public space in the old city of Guangzhou is ineffective, thus necessitating supplementation with a more systematic methodology. The “plug-in design” targets sustainable regeneration while preserving the overall urban texture and context, i.e., it has little impact on the spatial qualities of the old city. The ultimate goal is to activate the public space of the old city of Guangzhou point to area through the insertion of various plug-ins. In this study, the methodology is applied to Xudi Gaodi Street, the core area of the old city of Guangzhou, to explore its effects on sustainability. The internal public space is isolated and supplied with rigid and flexible plug-ins from multiple dimensions, which not only improves the spatial environment but also injects new urban formats. This work provides a specific solution for regeneration in Guangzhou’s old city while enhancing empirical knowledge of the plug-in design to support urban regeneration theory and further practical development.
The Effect of a Molasses Reductant on Acetic Acid Leaching of Black Mass from Mechanically Treated Spent Lithium-Ion Cylindrical Batteries

Published: September 2023

Recovery of valuable metals from end-of-life cylindrical lithium-ion batteries (LiBs) by leaching using acetic acid in the presence of an organic reductant is a promising combination to overcome environmental concerns that arise from employing inorganic reagents. This study investigated the effect of using molasses as a reductant in acetic acid leaching of a mixture of cathode and anode materials (black mass) prepared using mechanical treatments from spent LiBs. The effects of temperature, solid/liquid ratio, stirring speed, and acid concentration on the leaching of target metals (Co, Ni, Mn, and Li), current collector metal foil elements (Al and Cu), and Fe from the battery casing, with and without reductant, were investigated to obtain the optimum leaching conditions. The effect of adding the molasses at the start of leaching and after 1 h of leaching was tested. Acid leaching without molasses extracted the target metals Li, Ni, Co, and Mn with an efficiency <35% for all leaching parameters. However, the Al and Fe extractions increased as the acid molarity increased. Molasses addition at the start of leaching increased the extraction of the target metals to >96% at temperatures >50 °C. This is likely due to oxidation of the reducing sugars in the molasses that reduced the insoluble Co(III), Ni(III), and Mn(IV) components to soluble Co(II), Ni(II), and Mn(II) species, respectively. The kinetics of Co extraction in the presence of molasses were analysed, which has indicated that the rate-determining step in the Co leaching process is the reduction of Co(III) on the surface of particles in the black mass. Excess molasses can precipitate out target metals, especially Co, due to the presence of oxalic acid in the molasses. The reducing effect precipitated Cu(II) to Cu2O, and could further reduce Co to metal, which suggests that leaching with the optimum dosage of acetic acid and molasses may selectively precipitate copper.

Authors: Liu Yang , Ouyang Zhenhua , Yi Haiyang , Qin Hongyan
Published: September 2023

Rock burst is a multifaceted phenomenon that involves various intricate factors. A precise evaluation of its risk encounters numerous challenges. To address this issue, the present paper proposed a multilevel fuzzy comprehensive evaluation model based on the Analytic Hierarchy Process–Fuzzy Comprehensive Evaluation (AHP-FCE) method. Three primary influencing factors and twelve secondary influencing factors that impact the rock burst risk were identified. The mechanisms by which each influencing factor affects the rock burst were analyzed and the membership degree for each factor was calculated accordingly. The weight of each influencing factor was determined through the AHP. To obtain a quantitative evaluation result, the evaluation model was calculated using the second-order fuzzy mathematics calculation method. The application of the model was demonstrated on the 310 working face of the Tingnan Coal Mine, and the evaluation results were consistent with those achieved through the use of the comprehensive index method and the probability index method. All of the results exhibited consistent alignment with the actual circumstances. The verification process confirmed the scientific, effective, and practical nature of the model.
Analysis of Green Closed-Loop Supply Chain Efficiency under Generalized Stochastic Petri Nets
Authors: Liu Lang , Pu Yutao , Liu Zhenwei , Liu Junjie
Published: September 2023

In this paper, we aim to explore the operational performance of a green closed-loop supply chain under random events. A green closed-loop supply chain model based on generalized stochastic Petri nets (GSPN) is built using the Petri nets theory. According to the isomorphic relationship between GSPN and continuous-time Markov chains, the relevant Markov model is converted from GSPN, and the steady-state probability of the model is then calculated. Finally, the model is analyzed from the aspects of time performance and operation efficiency of each link. Compared to previous studies, this paper finds that: when the whole green closed-loop supply chain system reaches a dynamic equilibrium state, the product has a steady-state probability at all stages, and thus the overall operational performance of the system can be obtained; compared with the recycling of waste products, the green product takes a longer time in the production and distribution stages; since marketing, packaging processing, market feedback, and market demand formulation account for a high level of utilization throughout the life cycle of green products, decision makers need to focus on the supervision and management of these links. Managers of green closed-loop supply chain systems need to adjust their decision-making strategies in a timely manner according to the performance level of the system in the steady state to realize the efficient operation of the system. This paper not only provides theoretical support for the improvement of the operational efficiency of green closed-loop supply chain system, but also provides new ideas for the research of green closed-loop supply chain operation mode.

Authors: Alfarisi Salman , Mitake Yuya , Tsutsui Yusuke , Wang Hanfei , Shimomura Yoshiki
Published: September 2023

A product–service system (PSS) is a concept concerning sustainability, as it offers the opportunity to decouple economic success from material consumption, thereby reducing the environmental impact of economic activities. However, researchers have identified significant barriers frequently impeding sustainability potential, which are called rebound effects. Unfortunately, the existing studies are insufficient, and there are few published studies on the actual avoidance of the rebound effect, which is a significant limitation for practical applications for decision-makers and policymakers. Therefore, this study aims to conduct a comprehensive bibliometric review of the relationship between the rebound effect and PSSs, including its drivers and mitigation strategies. This study incorporates multiple perspectives to map and analyze the landscape of rebound effect research in the context of PSSs and used 152 articles from a systematic literature review covering all publication years. Using the Scopus and Web of Science database, journals, citations, authors, and keywords were identified. This study identified the annual trend of research, listed the most influential articles, and uncovered six research topic clusters related to the rebound effect and PSSs. As an innovative feature of this study, it categorised the identified drivers based on their contextual dependencies to elucidate their interrelationships. This study also presents a categorisation of mitigation strategies based on the type of approach. This study is expected to support decision-makers and practitioners in developing sustainable PSS implementation strategies.
Association of Per- and Polyfluoroalkyl Substances with Allostatic Load Stratified by Herpes Simplex Virus 1 and 2 Exposure
Authors: Boafo Yvonne S. , Mostafa Sayed , Obeng-Gyasi Emmanuel
Published: September 2023

Herpes Simplex Virus (HSV) 1 and 2 are persistent infections that affect a significant percentage of United States (US) adults, with 48% having HSV-1 and 12% having HSV-2. Using data stratified by HSV-1 and HSV-2 exposures, this study investigated the association of per- and polyfluoroalkyl substances (PFAS), a group of toxic synthetic organofluorine chemical compounds found in environmental, occupational, and home settings, with allostatic load (AL), an index of chronic physiological stress. Descriptive statistics, multivariable logistic regression, and Bayesian Kernel Machine Regression (BKMR) modeling were used to assess the effects of multi-PFAS exposures on AL using data from the National Health and Nutrition Examination Survey (NHANES) 2007–2014. Results indicated participants not exposed to PFAS exhibited 77% to 97% lower odds of higher AL (p < 0.001). For example, PFOS per unit increase brought forth a 2% odds increase in higher AL (OR: 1.02; 95% CI: 1.00, 1.05; p < 0.05). Participants exposed to PFAS had reduced odds of higher AL (77%–79%), regardless of their HSV-1 and HSV-2 status. PFAS exposure was more prevalent in those with HSV-1 (60%) than in those with HSV-2 (20%) infection, while AL levels were comparable in both groups (17%). BKMR revealed a nonlinear PFAS-AL association and confirmed interactions among PFAS. In summary, PFAS exposure increased the likelihood of higher AL among those with persistent HSV infections. Our study enhances the current understanding of the complex dynamics involving PFAS, persistent infections, and AL, which hold significant implications for public health and clinical intervention strategies.

Published: September 2023

Permanent forest reserves (PFR) in urban areas are an integral aspect of the urban forest concept and the basis of a city’s green infrastructure. The preservation of natural forests in urban areas has become a widely researched topic due to the environmental, social, and economic benefits provided by it. Although several studies have shown that visual aesthetics play a role in preserving natural forests in urban areas, visual aesthetic value is typically not prioritized in preservation plans since it varies based on the physical characteristics of natural forests in urban areas, making it difficult to measure universally. Therefore, this research aims to identify the suitable variables for assessing the visual aesthetic quality of permanent forest reserves within urban areas in Malaysia. This study selected two permanent forest reserves based on four criteria. Data were collected via participant-generated images taken along selected forest trails based on participant visual aesthetic preferences. Researchers and experts analyzed and classified the data according to content to identify suitable visual aesthetic quality variables. This research identified 14 suitable variables for assessing the visual aesthetics of PFRs in urban areas, with a dominant preference for information-processing theory variables. Mystery was the most present variable for the visual aesthetic quality assessment of PFRs. Furthermore, participants’ educational and emotional backgrounds, categorized as design, environmental, social, and technical, impacted their visual aesthetic preferences. Our findings serve as a foundation for assessing the visual aesthetic quality of natural forests within urban areas in Malaysia.
Viral Co-Infection in Bats: A Systematic Review
Authors: Jones Brent D. , Kaufman Eli J. , Peel Alison J.
Published: September 2023

Co-infection is an underappreciated phenomenon in contemporary disease ecology despite its ubiquity and importance in nature. Viruses, and other co-infecting agents, can interact in ways that shape host and agent communities, influence infection dynamics, and drive evolutionary selective pressures. Bats are host to many viruses of zoonotic potential and have drawn increasing attention in their role as wildlife reservoirs for human spillover. However, the role of co-infection in driving viral transmission dynamics within bats is unknown. Here, we systematically review peer-reviewed literature reporting viral co-infections in bats. We show that viral co-infection is common in bats but is often only reported as an incidental finding. Biases identified in our study database related to virus and host species were pre-existing in virus studies of bats generally. Studies largely speculated on the role co-infection plays in viral recombination and few investigated potential drivers or impacts of co-infection. Our results demonstrate that current knowledge of co-infection in bats is an ad hoc by-product of viral discovery efforts, and that future targeted co-infection studies will improve our understanding of the role it plays. Adding to the broader context of co-infection studies in other wildlife species, we anticipate our review will inform future co-infection study design and reporting in bats. Consideration of detection strategy, including potential viral targets, and appropriate analysis methodology will provide more robust results and facilitate further investigation of the role of viral co-infection in bat reservoirs.

Published: September 2023

The COVID-19 pandemic caused by the SARS-CoV-2 virus has inflicted significant mortality and morbidity worldwide. Continuous virus mutations have led to the emergence of new variants. The Omicron BA.1 sub-lineage prevailed as the dominant variant globally at the beginning of 2022 but was subsequently replaced by BA.2 in numerous countries. Wastewater-based epidemiology (WBE) offers an efficient tool for capturing viral shedding from infected individuals, enabling early detection of potential pandemic outbreaks without relying solely on community cooperation and clinical testing resources. This study integrated RT-qPCR assays for detecting general SARS-CoV-2 and its variants levels in wastewater into a modified triple susceptible-infected-recovered-susceptible (SIRS) model. The emergence of the Omicron BA.1 variant was observed, replacing the presence of its predecessor, the Delta variant. Comparative analysis between the wastewater data and the modified SIRS model effectively described the BA.1 and subsequent BA.2 waves, with the decline of the Delta variant aligning with its diminished presence below the detection threshold in wastewater. This study demonstrates the potential of WBE as a valuable tool for future pandemics. Furthermore, by analyzing the sensitivity of different variants to model parameters, we are able to deduce real-life values of cross-variant immunity probabilities, emphasizing the asymmetry in their strength.

Published: September 2023

Tenebrio molitor (mealworm) is one of the most promising insect species to produce sustainable feed and food with high nutritional value. Insects may harbour microorganisms both in the gut and on the exoskeleton originating from the rearing environment. Staphylococcus aureus is a pathogenic microorganism frequently involved in food poisoning due to its enterotoxin production. This study aimed to evaluate the S. aureus growth and enterotoxins production following an experimental inoculation into the T. molitor rearing substrate (about 7 log CFU/g). Analyses on the substrate and larvae were performed over a testing period of seven days. The microbial population dynamics were also evaluated through total viable count and lactic acid bacteria count. The effects of fasting, washing, and cooking on the microbial loads of mealworms were evaluated. The results highlighted that mealworms and substrates can maintain their microbial loads of S. aureus over the tested period. Moreover, fasting and washing were generally not able to significantly reduce (p-value > 0.05) S. aureus count in mealworms. On the other hand, cooking significantly reduced (p-value < 0.001) the microbial load in almost all cases. No production of enterotoxins was revealed during the trial. Therefore, microbiological risks can be reduced by a wise choice of substrate, appropriate control measures, and thermal treatment of larvae.
Joint Optimal Dispatch of Complex Urban Raw Water Supply: A Case Study of Lanxi City, Zhejiang Province, China

Published: September 2023

Water resources play a vital role in supporting urban economic and social development and ecological and environmental protection. Water shortage is a key factor that restricts the high-quality development of cities, while the coordinated and optimized allocation of urban raw water is an important measure to alleviate the water supply–demand imbalance. The current research on urban water supply issues and their underlying causes still needs to be further strengthened. Similarly, the formulation of rules for multi-source and cross-district water supply should pay more attention. This paper proposes a general analytical process consisting of four main stages: problem identification, system generalization, rule formulation, and model construction and solution for the joint optimal scheduling of raw water in a complex urban water supply system. This study investigates the significant water resource wastage and structural water shortage in the reservoirs of Lanxi City. The optimal scheduling plan is proposed by formulating rational rules for inter-district water supply and establishing a multi-source and multi-objective joint optimization scheduling model. Compared to the current independent scheduling scheme and multi-water source joint dispatching scheme based on the current dispatch diagram, the optimal scheduling plan effectively reduced the cumulative water shortage by 68.04 million m3 and 29.72 million m3, respectively, and increased the urban water supply guarantee rate in all districts of the city to over 90%. This study offers valuable insights to urban water resource managers, empowering them to develop optimal multiple water source supply rules that align to the specific characteristics of other case studies.
Mandatory Relationships and Sex Education (RSE) in England—Educators’ Views on Children’s Rights
Authors: Daly Aoife Caitriona , Heah Rachel
Published: September 2023

Comprehensive sexuality education (known as Relationships and Sex Education (RSE) in England), which is age-appropriate, accurate, realistic and non-judgemental, is a tool that enables children and young people to make informed decisions about their sexual health, sexuality and well-being. As such, it is crucial towards the realisation of many of the rights of children under the UN Convention on the Rights of the Child, such as, but not limited to, the rights to information, education and health. However, in the English guidance on RSE, there is very little consideration of children’s rights, and the requirement to involve parents in the shaping of RSE curricula as well as the right for parents to withdraw children from sex education lessons potentially hinders children’s access to RSE. In this paper, we discuss the views and experiences of teachers and professional educators to ascertain the position of children’s rights in the National Guidance on RSE and in the everyday practice of teaching RSE. Their views and experiences assist us in understanding some of the motivators and barriers to teaching RSE from the perspective of children’s rights. In analysing the English approach to RSE, we used Bourke, Mallon and Maunsell’s framework and considered RSE rights under the UNCRC from the perspective of the right to education; rights in education and rights through RSE.
Pre-diagnostic prescription patterns in bladder and renal cancer: a longitudinal linked data study
Authors: Funston Garth , Moullet Marie , Mounce Luke , Lyratzopoulos Georgios , Walter Fiona M , Zhou Yin
Published: September 2023

Background

Understanding pre-diagnostic prescribing activity could reveal windows during which more timely cancer investigation and detection may occur.

Aim

To examine prescription patterns for common urological clinical features prior to renal and bladder cancer diagnoses.

Design and setting

A retrospective cohort study was performed using electronic primary care and cancer registry data on patients with bladder and renal cancer, who received their diagnosis between April 2012 and December 2015 in England.

Method

Primary care prescriptions up to 2 years pre- diagnosis were analysed for five groups of clinical features (irritative urological symptoms, obstructive symptoms, urinary tract infections [UTIs], genital infections, and atrophic vaginitis). Poisson regressions estimating the inflection point from which the rate of prescriptions increased from baseline were used to identify the start of diagnostic windows during which cancer could be detected.

Results

A total of 48 094 prescriptions for 5322 patients were analysed. Inflection points for an increase in UTI prescriptions were identified 9 months pre- diagnosis for renal (95% confidence interval [CI] = 5.3 to 12.7) and bladder (95% CI = 7.4 to 10.6) cancers. For bladder cancer, the change in UTI antibiotic prescription rates occurred 4 months earlier in females (11 months pre- diagnosis, 95% CI = 9.7 to 12.3) than in males (7 months pre-diagnosis, 95% CI = 5.4 to 8.6). For other clinical features, no inflection points were identified and, as such, no diagnostic windows could be defined.

Conclusion

Prescription rates for UTIs increased 9 months before bladder and renal cancer diagnoses, indicating that there is potential to expedite diagnosis of these cancers in patients presenting with features of UTI. The greatest opportunity for more timely diagnosis may be in females with bladder cancer, who experienced the earliest increase in UTI prescription rate.

IMPLEMENTATION OF THE GRAPPLE METHOD IN PROGRESS ORDER APPLICATIONS IN THE FINISHING INDUSTRYAlong with advances in technology and information in all fields, one of which is in the field of furniture, especially in the finishing service industry. So far, orders have been received manually via telephone and WhatsApp. This is less effective because if the customer asks for a product that is still in the production process, the recipient of the order is less able to trace it due to the long finishing stages, many orders, less extensive production area, different products, and different processing times. Therefore, the progress order mobile application is used as an alternative solution to make it easier for order recipients to receive orders and to be able to monitor the process of working on the products being served. The system development method uses GRAPPLE and the research results from the feasibility study obtained material experts 95.8%, two shop owners 92.5% and 30 respondents 91.47% so it can be concluded that this application is feasible to use

This article aims to examine the effect of high dowry money in marriage against the postponement of marriage in Temerloh Village, Pahang State Malaysia in the perspective of maqashid shari'ah. This research is an empirical legal research, with a sociological approach to law. Data sources were obtained through interviews with a number of respondents and observations, which were then analyzed qualitatively. The results showed that there are still many people in Temerloh Village who practice dowry money so high that it has an impact on delaying marriage in several families in the village. The high dowry money is based on education, occupation and social status of the woman to be married. In the perspective of maqashid shari'ah, the high practice of dowry money that causes delays in marriage for those who are less fortunate is not in accordance with the aspect of hifz al-din (maintaining religion), because Islamic sharia advocates simplicity and ease in matters of dowry and financing in a marriage. Moreover, the postponement of marriage caused by the high amount of marriage dowry money is feared to result in actions that are not in accordance with religious values.

Published: September 2023

Depression has a serious impact that includes emotional, motivational, behavioral, physical and cognitive domains. One of the vulnerability factors for depression is the presence of stressful life events. According to the Humanistic view, a person can experience depression when they cannot fill their existence with meaning. Gestalt counseling is a counseling method that is often used in the humanistic approach because it has the main goal of achieving awareness centered on "here" and "now". One of the intervention methods in gestalt counseling is the empty chair technique. In this technique two chairs are placed in the middle of the room and the client sits while playing the role of top dog and under dog alternately. The subject in this study was a 44-year-old woman who experienced mild depressive episode disorder.  Data collection methods used are observation, interviews and psychological tests consisting of cognitive tests (WAIS), personality (Graphic), SSCT (Sack's Sentence Completion Test) and Back Depression Inventory (BDI). This research uses a quantitative approach with an experimental method using a single case pre test and post test design. Researchers used the empty chair technique to reduce depression in the subject. The intervention results show that the empty chair technique can be used as an intervention for patients with mild depressive episode disorder. This is evidenced by a positive change related to depressive symptoms in the subject. Meanwhile, based on the calculation of the BDI score, there was a decrease in the score from the original pre-test of 40 (severe depressive) down to 19 (Mild) in the post-test.
Why Burundi intervenes in the DRC: Self-interest to Pan-Africanist considerations?
Authors: Wielenga Cori , Hajayandi Patrick , Igba Samuel
Published: September 2023

Questions have abounded as to what Burundi’s motives and interests have been in sending troops, and spearheading the intervention in the eastern DRC.  With reference to the case of Burundi’s intervention within the East African Community’s (EAC) response to the growing conflict in the eastern DRC, this article considers a broad range of what Burundi’s motives and interests might be. This includes security and stability, both nationally and regionally, regional political dynamics and the position of Burundi within this, and trade and business opportunities.

This article discusses that in terms of intervention, while the realist perspective can help us to understand Burundi’s intervention in DRC to a large extent, an additional layer of complexity is the multifaceted relationships that African neighbouring states have with one another, and to the continent as a whole. Manifestations of this can be seen in the emphasis by the African Union and individual African states on ‘African Solutions to African Problems’, the principle of subsidiarity, and the Responsibility to Protect. These considerations not only place people at the centre of intervention as opposed to placing the state at the centre, but they also speak to issues of African agency, African resistance to external ‘interference’, Pan-Africanist interests and the decolonial concern of addressing the ongoing colonial legacy.
Ciudadanía en contextos migratorios:

Published: September 2023

El presente artículo se enmarca en un contexto complejo de debates contemporáneos y enfoques sobre ciudadanía, donde la participación ciudadana inmigrante en los niveles político, social y civil es evidente, limitada o favorecida, según sea el caso, pero presente. Por ello es relevante examinar las conexiones entre la construcción de ciudadanía a través de las experiencias intra y supranacionales de los inmigrantes, para ello se aborda el caso de los connacionales zacatecanos radicados en Estados Unidos, como una perspectiva representativa que puede abonar a la discusión, en la media de que la movilidad humana ha sido una característica singular y permanente en la historia global, y actualmente continúa siendo pertinente, con más de 272 millones de migrantes internacionales en el mundo. Sabedores de que la migración es uno de los problemas mundiales más importantes y apremiantes del siglo, pues de la totalidad que reconoce la Organización Internacional para las Migraciones (OIM) de la ONU, 68 millones son personas desplazadas externas; 25 millones son refugiadas; 40 millones son desplazadas internas; 4.8 millones son por estudios y profesionalización; 150.3 millones son trabajadores migrantes; 36.1 millones son niños; clasificación aproximada, lo que en sí encierra un objeto de análisis vasto.

"En las últimas dos décadas las migraciones internacionales han experimentado una acentuación significativo en el mundo, las disyuntivas y conflictos que presentan quedaron plasmadas en imágenes que recorrieron los medios de comunicación en el orbe, y desde la cual se ponía de manifiesto la violación a derechos humanos en las rutas migratorias: los muertos en el mediterráneo, los refugiados en Grecia e Italia, desplazamientos forzados en África Subsahariana, Ucrania y Siria, los controles fronterizos en la frontera sur de México son algunos de los casos que hoy ilustran la llamada “crisis migratoria”. La respuesta política desde la democracia ha sido establecer fuertes controles fronterizos, lo que ha potenciado en una criminalización de la migración provocando violencia y mayor vulneración a los derechos humanos de la población migrante..."

The hourly productivity of the milking parlour is significantly influenced by the organization of the technological process. Milkers perform a series of sequential operations (entry on the platforms, washing, drying, placing the milking units, removing them, disinfecting the teats, exiting the platforms of the milking parlour) the duration of which is a large part of the total milking time. The duration of the latent period from the release of oxytocin to its contact with the myoepithelial cells in the glandular part of the udder is from 30 s to 90 s (average 60 s). In this line of thought, the following questions arise: "in what time interval should the preparatory operations for milking be performed and what is their permissible duration". The aim of the present study is to develop methodologies (models) for simulating the work of milkers in "Parallel" type parlours. It was found that under the initially set working conditions of only two milkers in the milking parlour, all developed models are applicable for capacities up to 2x8. Models II, III and IV are unacceptable for capacities above 2x8, as the total duration of preparation of milking cows exceeds the time frame by between 30-80%. This finding proves that for a capacity over 2x8 it is necessary to perform technological operations with a larger number of milkers.

Peningkatan pemanasan global mengakibatkan radiasi matahari semakin panas dan dapat berdampak negatif pada kulit yaitu kulit kering dan kemerahan (sunburn). Penggunaan pelindung seperti sunscreen sangat diperlukan bagi wisatawan maupun penduduk Bali untuk mengurangi risiko penyakit kulit akibat radiasi ultraviolet. Ditengah banyaknya produk sunscreen yang beredar, selada laut (Ulva lactuca) sebagai sumber daya lokal diketahui memiliki aktivitas antioksidan, antiinflamasi, antihiperlipidemik, antimikroba, dan antivirus, serta memiliki karakteristik yang dapat menjaga kelembapan kulit dan fotoprotektif. Kebaruan dalam penelitian ini adalah aktivitas antioksidan dan antiradiasi krim ekstrak ethanol selada laut (Ulva lacuta). Penelitian ini bertujuan menganalisis aktivitas antioksidan dan antiradiasi krim ekstrak selada laut. Metode yang digunakan yaitu eksperimental dengan rancangan acak kelompok perlakuan ekstrak (0%, 0,5%, 1%, 1,5%, dan 2%), diuji aktivitas antioksidan dan antiradiasi krim ekstrak selada laut. Hasil dari penelitian didapatkan aktivitas antioksidan tertinggi yaitu IC50 109,67 (2%) dan nilai SPF tertinggi yaitu SPF 15,44 (sedang). Uji analisis ANOVA menunjukkan aktivitas antioksidan dan SPF krim ekstrak selada laut berbeda secara signifikan. Dapat disimpulkan bahwa krim ekstrak selada laut memiliki aktivitas antioksidan dan antiradiasi (SPF)

Kehamilan adalah periode yang menantang untuk perempuan terutama di masa pandemi. Masa pandemi yang panjang disertai dengan risiko terpapar yang tinggi, perubahan layanan kesehatan, dan kondisi lain yang membutuhkan adaptasi dan koping yang tepat sebagai perlindungan untuk ibu hamil. Kondisi yang banyak terjadi perubahan dan tidak bisa dipastikan tersebut menuntut adanya resiliensi pada ibu hamil. Kebaruan dalam penelitian ini karena menganalisis pengaruh dukungan sosial dan literasi kesehatan pada tingkat resiliensi ibu hamil di masa pandemi Covid-19. Penelitian ini bertujuan untuk menganalisis pengaruh dukungan sosial, dan literasi kesehatan sebagai prediktor resiliensi ibu hamil pada masa Covid-19. Penelitian ini menggunakan metode kuantitatif dan teknik purposive random sampling untuk memilih partisipan dari populasi, yaitu ibu hamil yang berdomisili di Yogyakarta, terdaftar di Poli KIA Puskesmas Yogyakarta, berusia antara 20 sampai 30 tahun berjumlah 230 orang. Sementara itu, untuk pengumpulan data, penelitian ini menggunakan skala resiliensi, dukungan sosial, dan literasi kesehatan. Teknik analisis yang digunakan adalah analisis jalur. Hasil penelitian menunjukkan bahwa dukungan sosial memiliki sumbangan efektif yang lebih besar dari pada literasi kesehatan sehingga nilai R-square resiliensi sebesar 0,212 yang berarti variabilitas resiliensi sebesar 0,212, yang berarti variabilitas resiliensi dapat dijelaskan oleh kedua variabel dukungan sosial dan literasi kesehatan sebesar 21,2%, maka dapat disimpulkan bahwa terdapat model mediasi yang tepat antara dukungan sosial dengan resiliensi dan religiusitas dengan resiliensi.

Susu formula adalah susu yang terbuat dari susu sapi atau kedelai yang telah dimodifikasi. Pemberian susu formula bayi harus disesuaikan dengan umur, kondisi bayi, dan sesuai dengan takaran saji. Menurut World Health Organization (WHO) atau Food and Agriculture Organization (FAO) pada tahun 2007, bubuk susu formula bayi tidak steril. Bahan tersebut mengandung bakteri yang dapat menyebabkan penyakit serius pada bayi. Hal ini didukung penemuan dari badan POM Amerika yang menemukan 14% susu formula terkontaminasi Enterobacter sakazakii (Cronobacter spp.). Bakteri pada susu mampu memperbanyak diri setiap 20 menit maka dianjurkan jangan mengkonsumsi susu yang sudah disiapkan lebih dari 2 jam. Kebaruan peneitian ini karena meneliti tentang bakteri pathogen pada minuman susu formula 2 jam setelah diseduh. Tujuan penelitian ini adalah untuk mengetahui cemaran bakteri patogen pada minuman susu formula 2 jam setelah diseduh. Penelitian ini adalah penelitian deskriptif. Jumlah sampel sebanyak 5 sampel susu formula 2 jam setelah diseduh. Data dianalisa dengan univariat yaitu dengan pengamatan secara makroskopis dan mikroskopis lalu dihitung menggunakan rumus persentase dengan rumus frekuensi jumlah sampel yang positif bakteri patogen dibagi jumlah sampel. Hasil dari penelitian ini ditemukan adanya bakteri patogen dengan persentase 100% yang terdiri dari jenis Bacillus cereus dengan persentase 60% dan Bacillus licheniformis dengan persentase 40%. Kesimpulan penelitian ini adalah ditemukan adanya pertumbuhan bakteri patogen (100%) dari 5 sampel yang diidentifikasi.
