Using a design exploration model to assess the global techno-economic feasibility of far offshore green hydrogen production towards 2050
Authors: Melles T. , Pruyn J.F.J. , Gelling J.L. , Wilde J.J. de
Published: June 2024

With space constraints onshore, strong renewable resources available far offshore and growing green hydrogen demand, far offshore green hydrogen production may be an attractive option. To assess this potential, a mixed integer quadratically constraint programming (MIQCP) optimization model was developed to find the cost per kilogram of far offshore green hydrogen in specific scenarios. The design of the far offshore green hydrogen supply chain was optimized with this model for six high potential scenarios in varying locations and the results were analyzed. It was found that far offshore green hydrogen costs are in the same order of magnitude as the costs of its alternatives. Far offshore green hydrogen may be considered marginally competitive with these alternatives from 2035 onwards in the analyzed scenarios when taking into account the considerable advantages of far offshore production, such as avoidance of scarce land usage in crowded areas and certain geopolitical considerations.

Authors: Rahaf Abdullah Alomair  , Dr. Syed Arif Pasha
Published: June 2024

The transformative impact of Electronic Health Records (EHRs) on healthcare quality in Saudi Arabia is the main focus of this study. The study examines how to implement EHRs to improve communication, make educated decisions, and ensure patient safety. It also discusses the advantages of doing so, including increased data accessibility and cost effectiveness. Issues with security and data interoperability are looked at concurrently. The study attempts to offer perceptive viewpoints on how the healthcare industry is changing while emphasizing how EHRs might improve overall quality control. As could be seen from above table, there is a positive and significant association between the all the variables under study. Hence our first two hypotheses have been substantiated. This means investing on training program could enhance quality as well as patient safety. Likewise, provision of best infrastructure also needs huge amount of financial resources. It could be seen from the result in table 2 that EHRs explained 26% variance in enhancing HCQ in Saudi healthcare system. Goodness of fit F= 277.112 found significant at p< 0.000. This implies that one percent investment in EHR cold increase HCQ by 51.4%. Likewise, the R2 for PST was recorded as .160 with F value 211.911 significant at 0.000, similarly for EHS, R2 was found as 0.121& with F value 292.820 significant at 0.000, all this led us to accept our hypothesis.

Psicanálise e ecologia
Authors: Wondracek Karin Kepler
Published: June 2024

A proposta do ensaio é redescobrir e re-situar-nos em relação à Terra e ao mundo mais-que-humano. No percurso, questionar saberes antropocêntricos e dualismos aprendidos que afastam os humanos do seu pertencimento ao mundo natural. As raízes comuns de Freud e da ecologia erótica de Weber na Fenomenologia da Natureza de Goethe tecem aproximações possíveis: a proposta é redescobrir-nos participantes e ligados em nossa identidade a esse mundo permeado de Eros. Com a escuta analítica “ampliada”, identificar possíveis “sons” dessa  ligação: no levantamento do recalque deste pertencimento; na ressignificação da morte pela natureza; na identificação de um outro mal-estar; na polissemia da escuta ampliada na clínica; no espelhamento da natureza em situações de dor e desamparo; na descoberta do enraizamento de nossa fala e escuta analítica na vivacidade dos povos orais. O convite aos psicanalistas é para se deixarem sensibilizar e expor ao unheimlich e ao erótico da Terra, e a também co-laborarem para o predomínio de Eros sobre as forças destrutivas que ameaçam a todos.
Colonialismo digital
Authors: Paim Filho Ignácio Alves
Published: June 2024

Essa resenha tem como objeto de interlocução o livro Colonialismo digital: por uma crítica hacker-fanoniana, de Deivison Faustino e Walter Lippold (2023). Nas páginas deste livro, potente e desafiador, vamos nos encontrar com a proposição de trazer para o debate público um tema até então negligenciado nos estudos coloniais digitais hegemônicos: sua relação com racismo. Afinal, como dizem os autores, não há capitalismo sem colonialismo e, não há colonialismo sem racismo. Racismo, em especial, o anti-negro. No decorrer da construção de suas ideias assinalam que não se trata de demonizar ou atacar o mundo informacional, mas sim, pensar como esse é utilizado para manutenção das ideologias de poder instauradas pelo capitalismo, ou ainda, o neoliberalismo. Os autores problematizam a lógica do colonialismo digital, com sua forma escravocrata contemporânea e buscam apontar caminhos para uma genuína emancipação dos povos subalternizados, em relação aos que detêm o controle da produção e execução do saber tecnológico, na sociedade informacional. Para viabilizar possíveis saídas deste cenário paradoxal e sinistro, recorrem ao pensar revolucionário de Fanon - o canibalização anticolonial - assimilação, transformação e criação; juntamente com o movimento do hacktivismo. Este que busca transgredir em busca do acesso e da construção de uma efetiva democratização que permita a tecnodiversidade.

Authors: Liu Aolong , Ma Yifan , Qiu Kexin , Qiao Han , Zhao Huawei
Published: June 2024

Objectives: With the accelerated aging of Chinese society, the demand for high-quality care services for the elderly population is rapidly increasing. In response, the Chinese government promotes the construction of home- and community-based elderly care (HCBEC) systems, which
significantly influence the life satisfaction (LS) of this group. In this study, we analyzed the relationship between the accessibility of HCBEC and LS of the elderly population in China and further examined the underlying mechanisms. Methods: We analyzed data from the 2018 China Health
and Retirement Longitudinal Study (CHARLS) using an ordered logit model. Results: HCBEC significantly enhanced the LS of the elderly population, with more pronounced positive effects observed among females, unmarried persons, rural dwellers, and those with chronic diseases or physical
disabilities. These services also increase their satisfaction by enhancing accessibility to anticipated care and medical services. Conclusions: This study theoretically complements research on LS. The use of large-sample data analysis ensures the reliability of the results, providing
practical implications for China's proactive response to population aging and policy, and enhancing the subjective well-being of the elderly population.

Authors: Walter Ofra , Hazan-Liran Batel
Published: June 2024

Objectives: In this study, we explored the relationships between psychological capital (PsyCap), social support, and academic adjustment in undergraduate students with learning disabilities (LD), comparing those receiving support from university centers to their unsupported peers.
PsyCap, comprising hope, efficacy, resilience, and optimism, is a critical determinant in the academic success of students with LD. We assessed the impact of PsyCap and social support on academic adjustment, comparing LD students who visited institutional support centers to those who did not.
Methods: The sample included 120 undergraduate students with various LD diagnoses, including attention deficit and hyperactivity disorders. Data were collected using 4 questionnaires. Results: There were statistically significant positive correlations between PsyCap and social support
but only among students receiving institutional support. Furthermore, academic adjustment was positively associated with both PsyCap and social support, regardless of institutional support. However, LD students attending institutional support centers showed higher levels of PsyCap, social
support, and academic adjustment than their counterparts who did not. Conclusions: The findings suggest institutional support enhances PsyCap-social support relations, underlining the importance of such support systems in educational settings. The study contributes to the understanding
of academic adjustment challenges faced by students with LD and underscores the value of targeted support strategies.

Published: June 2024

Objectives: Type 2 diabetes (T2D) and depression require self-management and resilience. Isolation during the early COVID-19 pandemic may have negatively impacted self-management behaviors in those with T2D and depression. We sought to determine differences in coping behaviors
associated with depression in those with T2D during the early pandemic. Methods: Using the All of Us Research Program, we analyzed a cohort of adults with T2D who completed the COVID-19 Participant Experience (COPE) survey in May-July 2020. We examined the association between having
a depressive disorder and responses to the question: "In the past month, to cope with social distancing and isolation, are you doing any of the following?" using regression modeling. Results: For the cohort with T2D (N=6,661), 41.6% had a depressive disorder. Those with depression
reported less "healthy" coping (AOR = 0.67, 95% CI [0.60, 0.74]) and more "unhealthy" coping, including: eating high fat or sugary foods (AOR = 1.61, 95% CI [1.40, 1.85]), eating more food than usual (AOR = 1.48, 95% CI [1.30, 1.69]), and smoking more cigarettes or vaping more (AOR = 1.88,
95% CI [1.37, 2.57]). Conclusions: Among adults with T2D, those with depression reported coping behaviors more likely to affect self-management plans negatively during the early pandemic.

Authors: Hariati Setia , Pardede A M H , Sihombing Marto
Published: June 2024

Image file protection is an important aspect in managing and transmitting visual data in today's digital era. One effective method for protecting images is to use the Discrete Cosine Transformation (DCT) algorithm based on the principle of randomization with key symbols. This research aims to describe the application of the DCT algorithm in the context of image protection using key symbols as a security method. This research includes the main stages, namely randomization of the original image using predetermined key symbols, transformation of the image to the DCT domain, and storage of the scrambled image. By scrambling the image using key symbols known only to authorized parties, the original image can be changed significantly so that it is difficult to reconstruct by unauthorized parties. In addition, the results of this DCT transformation can also be encrypted using a strong cryptographic algorithm, thereby increasing the security level of image protection. The research results show that this method is effective in protecting image files from unauthorized access and unwanted surveillance. The final result of implementing the DCT algorithm with this key symbol is an image that is protected with a high level of security and can be restored correctly by authorized parties using the appropriate key symbol. This research has broad potential application in a variety of contexts, including data security, confidential image storage, and secure image transmission over communications networks. Thus, this method can make a positive contribution in overcoming information security challenges in an increasingly complex digital era.

Published: June 2024

Tilapia (Oreochromis niloticus) is a type of fish that comes from rivers and lakes that connect the river. Tilapia was imported to Indonesia officially by the Freshwater Fisheries Research Institute in 1969, Tilapia fish breeds in Indonesia come from Taiwan as for the dark color with vertical stripes as many as 6-8 pieces and the Philippines which is red. The problems faced today related to testing the level of freshness still use conventional methods, namely by only seeing and sorting fish by sight or sight only.  This can certainly cause errors in choosing fish for ordinary people or who do not have expertise in choosing fresh fish. For this reason, a system is needed that can identify the freshness of tilapia using digital image management. Many methods are used in identifying an image, one of which is used by using the Backpropagation method.

The Potential Capabilities of two species of Azolla as a Bioaccumulator in Summer
Authors: Shome Gopa
Published: June 2024

Now a days, worldwide excessive use of chemical fertilizer, can have many undesirable effects on human health and the environment, which can be reduced or eliminated by adopting new agricultural practices such as use of organic inputs, namely manure, biofertilizer. On the other hand, water eutrophication has been a challenging global environmental problem recently. Plants can be grown in eutrophicated water, and after consumption from eutrophicated water, the harvested biomass of this plant can play important role as a useful green manure, rich in N P K. The use of Azolla, a N fixing water-fern can be a novel idea in this regard. Azolla spp. have a unique capability to accumulate more P, K within its body than its requirement and can be considered as NPK tablets. So, the experiment was conducted in order to find out the efficient species with regard to high biomass production with high accumulation of P, K, and tolerating higher concentration of media-P in summer. Light intensity and concentrations of media-P have a remarkable influence on the productivity and NPK accumulation of the species. Open area was more favorable than the partial shade for biomass production. Both the species have the capability to tolerate 60 ppm of media-P and produce their maximum biomass at only 15 ppm of media-P. A. filiculoides was found to produce more biomass, accumulate more tissue-P, contain more or less the same amount of N, and less K when compared with A. pinnata. Thus, in hot climate, A. filiculoides can be considered better accumulator of Phosphorus and A.pinnata can be considered better accumulator of Potassium being an effective scavenger of P, K.

This study sought to examine the effect of intellectual stimulation on performance of water works development agencies(WWDA) in Kenya and to determine the moderating effect of legal framework on the relationship between the intellectual stimulation and performance of water works development agencies (WWDA) in Kenya. A descriptive research design and positivist research paradigm was adopted. The population of this study was the 116 projects in the 8 Water Works Development Agencies (WWDAs) while the unit of observation was 116 projects in the organizations. This study employed stratified random sampling in selecting the sample. The study used primary data collected using a semi structured questionnaire. Data analysis was done using Statistical Package for Social Sciences (SPSS) computer software version 26. Qualitative data collected was analyzed using content analysis and presented in prose form. Quantitative data was analyzed using descriptive and inferential statistics. Descriptive statistics included mean, standard deviation, frequencies, and percentages. The study also computed correlation analysis to measure strength and the direction of linear relationship between variables. Regression model was fitted to the data to determine how the independent variable affect the dependent variable. The study further used hierarchical multiple regression models to measure the moderating effect of legal framework. The findings were presented in tables and figures. The study found that intellectual stimulation had a positive and significant relationship with the performance of WWDA in Kenya. On the moderator, the study found that legal framework has positive significant moderating effect on the relationship between intellectual stimulation and performance of WWDA in Kenya. Based on the findings, WWDA should encourage intellectual stimulation among their leaders to improve their performance. This can be done by providing opportunities for employees to engage in creative thinking and problem-solving activities. Leaders should also encourage employees to challenge their assumptions and biases, and to explore new and innovative ways of doing things. It is also important for leaders to provide training and development opportunities for their employees, which can enhance their knowledge and skills. Furthermore, leaders should create a culture of continuous learning, where employees are encouraged to seek out new information and ideas. Additionally, there is a need to establish effective legal frameworks that ensure transparency, fairness, and accountability in the management of public infrastructure projects, particularly those related to performance of WWDA in Kenya.

La ergonomía es la ciencia que se encarga de la evaluación de riesgos, así como el estudio de la relación que existe entre el hombre y su entorno laboral, analiza la manera en la que se realiza el trabajo y toma en cuenta las herramientas y movimientos que se ejecutan. Anteriormente se han realizado estudios ergonómicos los cuales muestran la importancia de estos, pues el realizarlos de manera adecuada propone soluciones en beneficio económico de las empresas, además de un impacto positivo en la salud de los trabajadores. El presente proyecto fue elaborado en una empresa manufacturera de la rama automotriz, en la cual se realizó un análisis ergonómico, comenzando con la aplicación de una encuesta, para posteriormente aplicar la metodología RULA como método para la evaluación de riesgos, del cual se obtiene un nivel de riesgo y un nivel de actuación. y, en base a estos se hace una propuesta de mejora para la mitigación de estos. A partir de la implementación del método RULA se obtuvo como resultado la identificación de tres posturas principales, las cuales comprometen la seguridad e integridad física de los trabajadores debido al alto nivel de riesgo. Los resultados obtenidos permitieron la propuesta de una mejora, que consiste en la implementación de un robot colaborativo, el cual, no solo mitiga el riesgo, sino que además, proporción un beneficio económico para la empresa.

A través de los últimos años los administradores de seguridad han influido en los desarrolladores de software para que diseñen software más resistente ante ataques de software mal intencionados, pero también en las metodologías y técnicas de seguridad que dan apoyo para detectar vulnerabilidades en la infraestructura de la información de una empresa, basado en el surgimiento de fraudes y robos de información que sufren organizaciones, emerge la práctica pentesting (Prueba de penetración), que es una de las técnicas más novedosas en cuanto a lo que a Seguridad Informática se refiere.Esta técnica es una forma de detectar vulnerabilidades tras implementarse, en beneficio de una empresa para reforzar aquellas fallas que pudiesen explotar los atacantes, es por ello que la meta principal es encontrar vulnerabilidades en las aplicaciones web. Con el pentesting se llevará a cabo una rastreabilidad exhaustiva de todas las vulnerabilidades que puedan ser encontradas. Los impactos y la probabilidad de explotación de cada vulnerabilidad encontrada también será calificada según el esquema estándar de puntuación de vulnerabilidad basándose en la metodología OWASP. Además, las vulnerabilidades se clasificarán según las consecuencias de la explotación identificadas a través de los hallazgos. Por lo que se proporcionará un informe con la recomendación para cada vulnerabilidad para atenuar o detener la amenaza. La rastreabilidad de vulnerabilidades se basará en procesos de trabajo y formas innovadoras de proteger toda aplicación web de las amenazas. Este reporte apoyaría a los desarrolladores, proveedores y usuarios de aplicaciones web a comprender mejor los posibles problemas de seguridad relacionados con las aplicaciones web y cómo deben ser tratados. Una manera de probar la robustez de un sitio es realizando una prueba de manera que se pueda atacar, esta técnica llamada prueba de penetración (Pentesting en inglés). Antes de lanzar un sitio, la seguridad de la red y de la aplicación web debe ser completamente segura y probada. Este estudio tiene como objetivo encontrar debilidades y fallas en las aplicaciones web. La prueba de penetración recopilará información sobre la fortaleza de las redes, los agujeros de seguridad y el acceso. El resultado del reporte es indicar las recomendaciones para mejorar la seguridad de una infraestructura de una organización. En cuanto a los resultados de las pruebas de penetración, la organización o empresa interesada puede corregir las vulnerabilidades que existen en el sitio web.La importancia de tener un sistema fuerte ante ataques e infiltraciones es el de evitar las vulnerabilidades, que son explotadas por un atacante malintencionado (atacante/hacker), por lo que puede afectar la confidencialidad, integridad y disponibilidad de una aplicación web o información distribuida.

En la línea 1 de bajo volumen la cual realizael ensamble de escaleras PODIUM se realizó un estudio de tiempos el cual tuvo como resultado variación en los tiempos de ciclo en las estaciones y tiempos de ciclo muyaltos lo que provoca que no se pueda cumplir con los requerimientos y la capacidad establecida de escaleras, el requerimiento promedio según el programa es de 396 escaleras/día. El cuello de botella surge de la estación demesa final la cual cuenta con 7 actividades siendo la estación de trabajo con una mayor carga de trabajo. De acuerdo con la literatura encontrada se cree que el balanceo de líneas puede nivelar las estaciones de trabajopara que tanto máquinas como operarios no tengan tiempos improductivos según menciona Hernández López (2014). Así como también el autor de la tesis tesis Peña Jara (2020), menciona que el Balanceo de línea es una herramienta de ingeniería que permite al profesional optimizar los procesos de manufactura. Se emplea un balanceo de líneas y herramientas para distribuir y optimizar de manera equitativa las tareas y trabajos en las estaciones de trabajo en la línea de los cuellos de botella y mejorar la eficiencia. Al realizar el balanceo en la línea 1 de bajo volumen se pudo cumplir con el objetivo de balancear e implementar herramientas de manufactura eliminando los cuellos de botella en la línea de bajo volumen de esta manera se pudo optimizar cada uno de los procesos y aumento la capacidad, por ende, aumentaron las salidas a 485 escaleras/día. Se eliminaron movimientos innecesarios al implementar la herramienta de 5S en la línea 1 de bajo volumen la cual permitió mayor flexibilidad.
