Urban development, driven by increasing population density, significantly impacts the physical environment, leading to issues such as flooding, food crises, and energy shortages. In response to these challenges, particularly in the context of urban flooding in Indonesia, the implementing team proposes the NeoHada solution. NeoHada is an adaptive design concept that integrates Solar-Piezoelectric technology and Rooftop Farming to create resilient and sustainable cities. This concept is based on three key principles: Climatic Architecture, Energetic Architecture, and Productive Architecture. The principle of Climatic Architecture is implemented through a Rain Harvesting System, where building rooftops serve as rainwater reservoirs to prevent flooding and provide an alternative water source. The Energetic Architecture principle combines solar panels and piezoelectric technology to generate independent electrical energy, alternating between rainy and dry seasons. The Productive Architecture principle emphasizes the development of rooftop farming as a means of achieving urban food self-sufficiency. The NeoHada solution is expected to realize the Sustainable Development Goals (SDGs) related to Zero Hunger, Clean Water and Sanitation, Affordable and Clean Energy, Sustainable Cities and Communities, and Climate Action. By integrating innovative technology and adaptive design, NeoHada aims to mitigate the negative impacts of urban growth and promote city resilience against various disaster and crisis scenarios. It is hoped that this solution will serve as a guide for the development of cities in Indonesia towards sustainable sustainability.

Authors: Al-Jarf Reima
Published: November 2023

This study aimed to explore the magazines and topics that female college students like to read, and the topics that senior and junior high school reading textbooks contain. Findings of questionnaire-surveys with female college students at King Saud University revealed that 77% of the students read women’s magazines; 77% like to read about fashion and make-up; 66% read articles about movies, singers, and actors; 24% read poetry; 1-4% read religious, educational, literary, political, computer and internet, and historical articles. Analysis of the reading schoolbooks showed that 10% of the reading texts are devoted to Quranic verses and Prophet Mohammed’s Hadiths; 29% are about Islamic history; 13% focus on general topics, and 11% deal with classical literature. It can be concluded that female college students like to read magazines and topics that prevail in satellite T.V. broadcasting and social media such as Instagram. Both magazines and satellite T.V. shows marginalize young people’s local culture and distract them from vital social, and political issues. There is a discrepancy between the types of topics students read at school and those they like to read at home. Therefore, this study recommends that reading texts in the school textbooks be re-selected, re-constructed and re-designed in terms of layout, colors, pictures, paper quality, and choosing an attractive cover. It also recommends the utilization of online courses, blogs, mind-mapping software, mobile reading apps and audiobooks, digital reading, global topics and global culture, speed reading practice, and reading from multiple resources. High school and college students should be introduced to new books, magazines, and e-books. Extensive reading of serious topics should be started from the primary grades; reading texts should be diversified; developing students’ appreciation skills and visiting book fairs, public libraries, publishing houses, cultural centers should be emphasized as well.

Published: November 2023

Implementation of a teacher presence system using geofencing and the Haversine Formula mobile-based method provides a modern solution for accurately monitoring teacher attendance. This system utilizes geofencing technology to set virtual boundaries around certain locations and the Haversine formula to calculate the distance between the teacher's current location and the school's location. If the teacher's location is within the boundaries of the area, the system assumes the teacher is present, and if outside, the system considers the teacher absent. Attendance status is regularly updated and stored in the database, providing an efficient method for administrators to monitor teacher attendance and increase accountability. The use of this system reduces the possibility of manual errors, making it a valuable tool in education. Two tests were carried out, namely testing the accuracy of the system and testing black box testing. Accuracy testing was carried out under three conditions, namely inside the presence area, at the border of the presence area, and outside the presence area. The test was carried out 30 times and resulted in 100% accuracy. then blackbox testing also concludes that the application works in accordance with the testing that has been done. The conclusion from this research is that the higher the device and network used, the more accurate it will be.

The methods. The results of the study were obtained by means of a feasibility study for the comparison of five different schemes of transportation of enrichment tailings: rail transport, belt conveyor, rope-belt conveyor, tubular conveyor, pipeline. A comparative assessment of capital costs, annual operating costs and the number of employees of the process of transportation and storage of enrichment tailings in the mined-out space of the spent mine was carried out. Findings. The issue of transportation of iron ore enrichment tailings in conditions of open development of mineral deposits is considered. Different types of transport were considered from the point of view of delivery and storage of enrichment tailings. It has been established that the most effective modes of transport, from the point of view of cost reduction and environmental protection, are a tubular conveyor for transporting dry mass and a pipeline for pulp. It has been established that in some cases –provided there is a corresponding technological necessity –it is advisable to use the lower branch of the tubular conveyor for transportation. The originality. The dependence of capital and annual operating costs for the transportation and storage of enrichment tailings in the spent pit on the considered options for transportation by rail transport, belt conveyor, rope-belt conveyor, tubular conveyor, and pipeline was established. The dependence of the change in the number of workers involved in the process of transportation and storage of enrichment tailings on the scheme of their transportation has been established. Practical implementation. Reasonable conditions for the use of a tubular conveyor for the transportation of enrichment tailings to the produced space of the spent pit and to the beneficiation factory are substantiated. In schemes that provide for the reprocessing of enrichment tails, both branches of the tubular conveyor can be used as transport: the lower and the upper.

Published: November 2023

En el contexto económico actual, la relación entre la sostenibilidad y el rendimiento financiero en las pequeñas y medianas empresas (PYMES) es un tema de investigación que ha cobrado una gran relevancia. En los últimos años, ha surgido un creciente interés por entender cómo la incorporación de prácticas sostenibles puede influir en el desempeño financiero de estas empresas, no solo es vital para el sector empresarial, sino también para el desarrollo económico y ambiental de la sociedad en general. El presente estudio tiene como propósito principal analizar sistemáticamente la comparación entre la sostenibilidad y el rendimiento financiero en las Pymes. Se implementó una revisión sistemática de la literatura utilizando Google Scholar como herramienta de búsqueda, con un enfoque temporal entre 2018 y 2023. Los criterios de inclusión y exclusión garantizan la recopilación de estudios académicos relevantes y rigurosos. Se empleó un proceso de revisión doble. El análisis descriptivo y de meta-análisis, siempre que los datos lo permitieron, reveló que las PYMES que adoptan prácticas sostenibles tienden a tener un mejor desempeño financiero a largo plazo. No obstante, existen variaciones significativas, dependiendo del sector, la geografía y la estrategia de implementación de sostenibilidad. Las conclusiones sugieren que la sostenibilidad puede ser una ventaja competitiva para las PYMES y resaltan la necesidad de un compromiso más profundo con la sostenibilidad. La falta de estudios longitudinales y la heterogeneidad en la definición de "sostenibilidad" indican la necesidad de más investigaciones. Este estudio sienta las bases para futuras exploraciones en esta área crítica.
Substantial Shift in Palliative Care from Hospice to Community and Its Integration into Community-Based Primary Health Care
Authors: Sakitani Mitsuru
Published: November 2023

In 1967 Cicely Saunders founded St. Christopher’s Hospice. Then, Saunders’ hospice model of palliative care promoted palliative care movement in the world. World Health Organization (WHO) adopted this hospice model, but WHO has gradually improved palliative care and integrated it into community-based comprehensive care. This review focuses on the recent substantial shift in palliative care from hospice to community and WHO’s leadership in integration of palliative care into primary health care. We summarized Saunders’ hospice model, WHO’s improved model in 2002 and the complemented model proposed by the International Association for Hospice & Palliative Care (IAHPC) in 2019. Then, we delineated the development steps of WHO’s integration of palliative care into primary health care. We also showed integration of supportive care in cancer and existential therapy/care into primary health care. Thus, various limitations of Saunders’ hospice model (palliative care for patients with cancer only at the terminal stage and Christian religious care) have been overcome by WHO’s integrated primary health care model that provides care for noncommunicable (including cancer) and communicable diseases during all the continuity of care. Further education and training of the participants in community-based primary health care are required to address all the needs of patients and families in community.

Published: November 2023

Generally, most of the hematological and biochemical parameters in SCD patients are different from that of the other population. Hence, the importance of laboratory reference values for SCD has received a wide attention lately. However, there is a few reliable data to serve as reference values for hematological and biochemical parameters in patients with SCD in most African countries [3]. This study aimed at determining the hematological parameters in adults with sickle cell disease visiting the University College Hospital, Ibadan, Nigeria, with a view to providing a predictive data of SCD patients hematological parameters, as well as contributes to effective management of the disease. 131 participants were studied, 95 were sickle celled while 36 were healthy controls. Plasma was separated from collected blood and used to determine the haematological parameters. Results showed that the mean age was 35.4years ±SD=7.54years with a range of 19 to 56years for sickle cell subjects and 36.8years ±SD=9.11years with a range of 19 to 58years for control. The male to female ratio was approximately 2:1 and 2.4:1 in control and sickle cell subjects respectively. All respondents (100.0%) had abnormal haemoglobin, (78.9%) had abnormal leucocytes and 21.1% had abnormal platelets. Student’s t-test revealed that there was no significant relationship between the haematological parameters assessed in the HBSS patients (Haemogloblin vs Leucocytes, 093(.369), Haemogloblin vs platelets, 031(.767), Leucocytes vs platelets, .023(.825). It is therefore advisable to always check for each parameter and never use one to predict the other, for effective management of sickle cell disease.

O ciclo hidrológico natural é composto por diferentes processos com o percurso da agua pluvial definido pela natureza, e quando o ser humano passa a fazer parte desse sistema, ele produz alterações que modificam negativamente este ciclo e geram impactos significativos que estão diretamente ligados ao ciclo da água, e dessa forma acarretam em danos e prejuízos à população, gerando inundações, modificando o escoamento superficial e subsuperficial, podendo desencadear ou aumentar erosões e assoreamentos de rios urbanos, logo o intuito desse estudo é entender o que tais modificações ocasionam no ciclo hidrológico, através da impermeabilização do solo derivado da urbanização, e a influência do escoamento superficial devido ao deflúvio acarretando no aumentando da vazão pluvial influenciado pela permeabilização do solo, através de meios comparativos estudando a vazão das aguas pluviais, em um contexto atual e futuro, do escoamento superficial, estimando uma possível urbanização na região localizada a montante do bairro Ouro Verde em Açailândia-MA.

Este estudo objetivou identificar a frequência de VDRL positivos em indivíduos atendidos em um laboratório de análises clínicas na cidade de São José dos Campos/SP, considerando faixa etária, gênero e gestantes, além de determinar em qual grupo houve maior incidência de VDRL positivo. Foi realizado um estudo transversal que utilizou o banco de dados de um laboratório de análises clínicas de São José dos Campos, no qual, foram analisados 3.427 laudos laboratoriais entre abril de 2022 a abril de 2023. Antes do início da pesquisa, o trabalho foi submetido e aprovado pelo Comitê de Ética em Pesquisa da Universidade Paulista, sobre o parecer de número 68294523.4.0000.5512. O estudo revelou uma taxa de 4,26% de testes VDRL reagentes, sendo que a doença foi mais elevada entre os homens, com uma taxa de 8,24%, em comparação com a taxa de incidência de 2,87% no grupo das mulheres. A faixa etária com maior incidência foi a de 21 a 29 anos, com 36,99% dos casos, enquanto os achados nas gestantes revelaram uma prevalência de 2,63%, com idades compreendidas entre 20 e 35 anos. Portanto, conclui-se que a sífilis continua com taxas elevadas, principalmente em homens e indivíduos na faixa etária entre 21 e 29 anos. Dessa forma, ressalta-se a importância da educação sexual, conscientização e programas de prevenção voltados para esse grupo. Ademais, a sífilis em gestantes, ainda é uma preocupação significativa, sendo necessário reforçar os cuidados pré-natais.

Introdução: A Depressão Resistente ao Tratamento (DRT) não apresenta um consenso absoluto sobre sua definição, mas pode ser entendida como o quadro depressivo grave com resposta insatisfatória a dois antidepressivos de duas classes diferentes. A cetamina é um dissociativo anestésico que possui ação antagonista dos receptores de glutamato/aspartato, logo, age no quadro fisiopatológico da depressão. Objetivo: O presente estudo busca examinar as particularidades do uso de cetaminas em pessoas que não apresentam melhora com os tratamentos convencionais para a depressão. Materiais e Métodos: Trata-se de uma revisão integrativa de literatura acerca do papel da utilização de cetaminas em pacientes refratários ao tratamento. Utilizou-se a estratégia PICO para a elaboração da pergunta norteadora. Ademais, realizou-se o cruzamento dos descritores “Depressão refratária”; “Cetaminas”; “Manejo”, nas bases de dados National Library of Medicine (PubMed MEDLINE), Scientific Eletronic Library Online (SCIELO), Ebscohost, Google Scholar e Biblioteca Virtual de Saúde (BVS). Resultados e Discussão: A depressão refratária é grave sem definição clara. Tanto a cetamina como a eletroconvulsoterapia (ECT) são consideradas tratamentos satisfatórios e não demonstram diferenças na redução da ideação suicida nesses pacientes. Conclusão: Essa revisão destaca que para o melhor manejo da DRT é preciso formalizar o protocolo de abordagem terapêutico deste transtorno. Além disso, revela que as cetaminas apresentam resultados superiores a outras medidas farmacológicas e é muito semelhante à ECT, porém requerem acompanhamento devido ao alto índice de recorrência.

Sistemas de criação com ovinos, principalmente no estado do Rio Grande do Sul, são manejados sob pastagens naturais com baixo investimento, que em determinadas fases do ano, não atendem as exigências para mantença. Desta forma, no período hibernal, a introdução de espécies forrageiras e o uso de suplementação alimentar tornam-se estratégias eficientes para potencializar o desempenho de cordeiras. Nesse sentido, o objetivo do presente estudo foi avaliar o desempenho de 24 cordeiras da raça Texel, com peso corporal médio de 25,79 ± 3,21 kg e idade média inicial de seis meses, sob diferentes manejos alimentares na pastagem de azevém. O experimento foi conduzido em área pertencente a Universidade Federal de Santa Maria/RS, Brasil. O método de pastejo adotado foi o de lotação contínua com taxa de lotação variável para manutenção da massa de forragem de 1200 a 1500 kg de MS ha-1. Os sistemas alimentares consistiram em azevém (Lolium multiflorum Lam.) com 150 kg de nitrogênio (N) ha-1   , azevém consorciado com leguminosas com 75 kg de N ha-1 e azevém com fornecimento de suplemento na proporção de 1% do peso corporal (PC) com 75 kg de N ha-1. O delineamento experimental foi inteiramente casualizado, com medidas repetidas no tempo, com três tratamentos e quatro repetições de área. O peso corporal final e o ganho médio diário das cordeiras do sistema alimentar em que foi fornecido suplemento foram, respectivamente, 15,28% e 30,76% superiores quando comparado às cordeiras do sistema alimentar com inclusão de leguminosas e, respectivamente, 6,50% e 11,47% superiores comparado ao sistema alimentar somente azevém. Conclui-se que cordeiras em azevém e recebendo suplemento apresentam maior desempenho corporal em comparação às exclusivamente em pastejo.
