Fever of unknown origin can be a symptom of at least 200 diseases. Positron emission tomography-computed tomography, although highly informative, may not be readily available as an imaging tool. We present a clinical case of giant cell arteritis where computed tomography played a key role in arriving at a diagnosis.
A 61-year-old woman presented to the hospital with a nocturnal fever up to 39.5С, accompanied by chest and scapular pain, and substantial weight loss (10 kg over 3 months). Lymphoproliferative and infectious diseases were excluded. Baseline colonoscopy had revealed erosions in the colonic mucosa, leading to a preliminary diagnosis of ulcerative colitis, and subsequently, the patient was admitted to the gastroenterology department. Follow-up colonoscopy had excluded this diagnosis. Additional imaging via chest and abdominal computed tomography scan revealed wall thickening of aorta and its branches with subtle contrast enhancement.
Conditions, such as tuberculous aortoarteritis and syphilitic aortitis, were excluded. The patient was diagnosed with giant cell arteritis involving brachiocephalic trunk, subclavian arteries, and celiac trunk. Prednisolone was administered with subsequent reduction in symptoms.
Although computed tomography may not be regarded as the gold standard for the differential diagnosis of fever of unknown origin, this case underscores its valuable contribution in establishing a definitive diagnosis.

Published: August 2023

BACKGROUND: With the increase in rotation speeds of turbomachinery shafts, particularly for aviation and space applications due to the requirements for compactness and mass reduction, the issue of bearing life becomes relevant. For such devices, it is promising to use gas lubricated petal bearings (GLPB), which do not require additional systems and operate on the gas of the turbomachine working flow with excellent damping characteristics. Despite the attractiveness of GLPB designs, they are difficult to calculate because the direct work is performed by a thin layer of gas instead of balls, as in classical bearings. The efficiency of a GLPB depends directly on its design, especially the shape of the lobes and the amount of clearance between the shaft and the lobe.
AIM: To develop a mathematical model of the operation of a gas lubricated lobe bearing to determine the pressure distribution across the lobe surface and the corresponding computer program for calculations.
METHODS: Computational modeling of radial GLPB operation is accomplished with the determination of pressure in the lubrication layer. Moreover, its corresponding integral characteristics within the Reynolds model and the equation for the height of the lubrication layer under several assumptions are determined.
RESULTS: In this research, a computer program has been developed that allows for automated calculation of the space of change of variables and functions, the layout of a single table and output, construction of a volumetric model for its subsequent use in CAD systems, and generation of pressure graphs. Herein, the calculation of each variant is faster than similar calculations in the MathCAD environment. The same convenience consists of the block structure of the program, the visual setting of interrelations between blocks, and various and understandable outputs, suitable for both the report (construction of graphs) and drawings and visualization.
CONCLUSION: A specialized software package for parametric optimization of gas dynamic characteristics of GLPB has been developed. The developed tool permits the calculation of several cases and facilitates the selection of the optimal gap shape based on numerous proposed criteria. Among other things, the calculation allows us to see the variations in a different operating mode of the plant, use of a different substance with different dimensions, and choose the optimum that will suit a particular plant. Moreover, it is possible to expand the limits of applicability of petal bearings, such as at low speeds or large diameters.

Authors:   , Diallo Sona , Quinlan Jennifer J
Published: August 2023

Food insecurity is defined as the inability to consistently access sufficient nutritionally- adequate and safe food through socially acceptable means. It is estimated that more than 33 million people are food insecure in the United States (USDA, 2022). Recent research has found that food insecurity is also present to varying degrees on college campuses. This study aimed to examine the prevalence of food insecurity among undergraduate students at Drexel University and their awareness of Mario's Market, a food pantry on campus. A modified version of the Food Security Survey Module was distributed via Qualtrics to approximately 13,000 students enrolled at Drexel University, a private research institution in Philadelphia, PA. Responses included 748 undergraduate participants. Findings revealed that 41% (n= 308) of respondents identified as food insecure, while 59% (n= 440) did not. Additionally, Black/ African American, American Indian/ Alaska Native, Other, and participants who preferred not to disclose their race experienced higher levels of food insecurity compared to their White/ Caucasian and Asian counterparts. In terms of awareness of Mario's Market, 51.7% (n= 381) of respondents were aware of the existence of the food pantry, while 48.2% were not. Participants highlighted several barriers that hindered their ability to access the food pantry, including feelings of embarrassment, perceptions that others needed it more, and limited availability of fresh, whole foods. These insights can inform future interventions and initiatives to address food insecurity on campus, ultimately striving towards a more supportive and nourishing environment for all students.
Development of a Finite Element Model of the Thoracic and Lumbar Spine with Ribs for Idiopathic Early Onset Scoliosis
Authors:   , Divekar Manav , Balasubramanian Sriram
Published: August 2023

Early onset scoliosis (EOS) is a spinal curvature condition affecting children below the age of 10 years. It can lead to progressive spinal and ribcage deformities, causing thoracic insufficiency syndrome (TIS) and respiratory difficulties. The current treatment options for EOS lack consensus among clinicians, necessitating the development of computational models to assist in pre-operative planning and surgical technique selection. Finite Element (FE) modeling, widely used in various medical applications, can play a crucial role in this regard. However, current FE models for EOS are limited and not patient-specific. This study aims to develop a patient-specific (PS) FE model of the thoracic and lumbar spine with 12 pairs of ribs for a one-year-old idiopathic EOS subject. Such an FE model can serve as a template for creating individualized PS-FE models. Retrospective chest and abdominal CT scans of a one-year-old male idiopathic EOS patient were obtained after Institutional Review Board approval. CT images were processed using 3D Slicer software to digitally reconstruct the anatomical structures. Hexahedral meshes were created using Ansys ICEM CFD and Hypermesh software, incorporating the segmented geometries of vertebrae, ribs, intervertebral discs (IVDs), and spinal ligaments. The block structures were generated based on the individual vertebra and rib geometries, ensuring an accurate representation of anatomical features. Soft tissues, including IVDs and spinal ligaments, were modeled using appropriate meshing techniques. The final FE model consisted of 335,669 high-quality hexahedral elements. The developed FE model represents the first comprehensive hexahedral model of the thoracic and lumbar spine, including ribs, for a one-year-old idiopathic EOS subject. This model serves as a foundational template for creating patient-specific FE models in the future. Such FE models will help stimulate growth and surgical procedures, providing valuable insights for clinicians in surgical technique selection and treatment planning. The high-quality mesh elements meet the criteria for acceptable mesh quality. In conclusion, the idiopathic EOS patient-specific FE model presented in this study offers a significant advancement in the development of computational modeling tools to aid in the understanding and management of idiopathic EOS. Such FE models will help lay the groundwork for future research and clinical applications, facilitating personalized treatment approaches and improved outcomes for pediatric patients with EOS.
The Plasticity of Intercellular Communication and The Polarization of Glial Cells in Pain Centers Following Spinal Cord Injury
Authors:   , Freeman Daniel , Detloff Megan R , Garcia Anna Denise R.
Published: August 2023

Spinal cord injury (SCI) is a neurological condition which often results in the development of chronic pain. In addition to neuropathic pain brought about by the injury itself, inflammation can drive pain signal transmission by contributing to the hyperexcitability of nociceptors and second order neurons in the dorsal root ganglia (DRG) and dorsal horn of the spinal cord, respectively. One of the key mediators of inflammation in pain centers is Sonic hedgehog (Shh) signaling in glial and immune cells. This signaling pathway has been shown to have neuroprotective effects including the resolution of inflammation. In addition to Shh signaling, glial and immune cell polarization to neurotoxic and neuroprotective phenotypes can contribute to the inflammatory nature of pain centers. This body of work examines the roles of Shh signaling and glial and immune cell polarization in contributing to inflammation and the development of chronic pain following SCI. A conditional knockdown of Shh signaling did not further increase pain following SCI compared to wildtype mice with SCI. However, when looking at the relative expression of markers pertaining to neurotoxic and neuroprotective populations of glial and immune cells, as well as the secretory factors that comprise the microenvironments of the dorsal horn and DRG, we find that certain analytes contribute to the development of pain following SCI moreso than others. These studies serve as a basis for ongoing work pertaining to the identification of targets and the development of therapeutics aimed at reducing pain in individuals who have sustained a SCI.

Published: August 2023

The purpose of this transcendental phenomenological study was to explore the lived experiences of Latinx graduates who had interactions with professionals represented in the Behavioral Assessment and Intervention Team (BAIT) at a small, private college during their undergraduate experience. While BAITs on college campuses can be effective intervention during emergent situations, they can also be used to intervene when a student is struggling. With changing demographics on college campuses, BAITs have an opportunity to provide focus for the best strategies for Latinx students. By interviewing Latinx college graduates from a smaller sized institution, through phenomenological discovery, the researcher worked with the emerging themes to explore the following questions: (1) How do Latinx graduates describe the essence of their lived experiences with BAIT professionals in college? (2) How do Latinx graduates describe their lived experience of persistence to graduation? (3) How do Latinx graduates describe the factors that contributed to their persistence to graduation? Semi-structured, one-on-one interviews and the collection of artifacts recorded the experiences of five Latinx graduates as they reflected on their collegiate experiences. Data analysis using qualitative, thematic coding revealed themes of family connections, complexity of identity, and connections to campus. These themes identified how participants were shaped by familial relationships, how identity shaped their experiences, and how community was created during their time in college. The reflections of these graduates shaped the findings of this study and guided suggestions for best practices for supporting Latinx college students in their persistence to graduation.

Stress is a condition that burdens a person and affects homeostasis resulting in health problems, including dental and oral health. Stress can be caused by physical, chemical, or psychological stressors. Stressors cause an increase in blood glucose levels due to an increase in the stress hormone cortisol. This study aims to determine the effect of physical-psychological and psychological stress induced by electrical foot shock on blood glucose levels in rats. This research is an experimental laboratory study with a post-test control group design using white male rats as animal stress models. Animal models were divided into six groups, namely physical-psychological stress for 7 days (PPS1), 14 days (PPS2), and 28 days (PPS3); and psychological stress for 7 days (PS1), 14 days (PS2), and 28 days (PS3). The animal models were placed in the experimental box with electrical foot shock. The physical-psychological stress treatment was to flow an electric current of 48 V, 0.5 Hz, 2 mA for 30 minutes daily. In the psychological stress treatment, the animal models were placed without an electric shock, but the animal models were placed together, given an electric shock stressor separated by transparent plastic with a thickness of 5 cm and foam at the bottom of the cage (insulator). The results showed that although there was no effect of electrical foot shock on blood glucose levels in rats experiencing physical-psychological stress for 7, 14, and 28 exposures (p0.05), electrical foot shock affected blood glucose levels in rats with psychological stress (p0.05). It can be concluded that physical-psychological and psychological stress induced by electrical foot shock affected blood glucose levels.

Published: August 2023

Penelitian ini melihat pengaruh parameter-proses thermoforming, yaitu waktu pemanasan, pre-stretching degree, dan tingkat evakuasi vakum, terhadap distribusi ketebalan dinding dan akurasi dimensi produk plastik yang diproses dengan thermoforming. Penelitian dilakukan serangkaian percobaan dengan tiga variasi parameter-proses tersebut.   Waktu pemanasan divariasikan masing-masing 30, 35 dan 40 detik, pre-stretching degree dari 0,1 hingga 0,3, dan evacuation rate dalam nilai 6 mm/detik, 8 mm/detik dan 10 mm/detik. Hasil penelitian menunjukkan bahwa parameter yang mampu meminimalkan radius pada sudut specimen adalah: tingkat evakuasi 10 mm/detik, waktu pemanasan 40 detik dan derajad pre-stretching 0,1 Vst.   Hasil produk vacuum forming dapat dioptimalkan dengan kombinasi tingkat evakuasi vakum yang tinggi, waktu pemanasan lebih lama dan derajad pre-stretching rendah. This study examines the influence of thermoforming process parameters, namely heating time, pre-stretching degree, and vacuum evacuation rate, on the distribution of wall thickness and dimensional accuracy of the product. The research involved a series of experiments with three variations of these process parameters. Heating time was varied at 30, 35, and 40 seconds, pre-stretching degree ranged from 0.1 to 0.3, and evacuation rates were set at 6 mm/s, 8 mm/s, and 10 mm/s, respectively. The results showed that the parameters capable of minimizing the radius at the specimen's corners were a vacuum evacuation rate of 10 mm/s, a heating time of 40 seconds, and a pre-stretching degree of 0.1 Vst. The findings suggest that the vacuum forming products can be optimized by combining a high vacuum evacuation rate, longer heating time, and low pre-stretching degree.

Published: August 2023

En el campo de la ecología de las comunidades ícticas uno de los principales desafíos ha sido entender los cambios longitudinales de la estructura y diversidad de los ensamblajes en ecosistemas loticos, y saber si estos están influenciados por factores abióticos y bióticos. En ese contexto, nos propusimos determinar la estructura y la diversidad de los ensamblajes ícticos en un gradiente longitudinal y su relación con algunas características del hábitat y las coberturas en ríos costeros de la Sierra Nevada de Santa Marta (SNSM). Se analizaron 13 estaciones distribuidas en siete ríos costeros de la SNSM; los peces se recolectaron con un equipo de electropesca en un transecto longitudinal de 100 m de largo, realizando bloqueos con una red de arrastre (5 m x 1,5 m). La estructura y composición se analizó mediante el escalamiento multidimensional no métrico (EMNM) usando el índice de Jaccard y modelos de distribución-abundancia. Para determinar la diversidad se utilizaron los números de Hill (1973) y un análisis de redundancia (AR) para evaluar la relación de las variables ambientales con los ensamblajes. El EMNM y los números de Hill evidenciaron que los ensamblajes estaban estructurados según la distancia hasta la desembocadura en cuatro grupos, tres de ellos ajustados al modelo de Zipf y uno al de preferencia de nicho. El AR evidenció que el patrón longitudinal observado se explicaba por el tipo de sustrato y la cobertura vegetal. Los resultados indicaron que los ensamblajes ícticos parecen obedecer a un gradiente longitudinal, lo que tendría implicaciones importantes para la conservación.

Objectives: We aimed to evaluate the potential prognostic factors of patients with primary central nervous system lymphoma (PCNSL).
Methods: Thirty-two patients with PCNSL were retrospectively analyzed.
Results: All the patients received high doses of methotrexate-based chemotherapy as the first-line treatment. Overall survival was 30.0 ± 7.2 months. Those with partial response and without response had a higher risk of mortality. The increased leukocyte and neutrophil levels were associated with high mortality. Besides, the SIIL as a product of the systemic immune inflammation (SII) and lactate dehydrogenase (LDH); the SIRIL as a product of systemic immune response index (SIRI) and LDH; and the NLL as a product of neutrophil-lymphocyte ratio and LDH were taken into consideration for the first time for the purposes of the present study. Elevated NLL, SIIL, and SIRIL indexes were associated with mortality. Elevated SIIL level, radiotherapy, and partial and no response were the independent predictors of mortality on the basis of the multivariable regression model including the risk factors associated with mortality.
Conclusions: SIIL, SIRIL and NLL are prognostic factors in PCNSL. Determining the prognostic factors and risk profile may predict the requirement for more intensive treatment, especially in young patients at high risk.

Published: August 2023

Ante la pandemia del SARS-CoV-2, la economía mundial vive una crisis económica y social sin precedentes. Se paralizaron muchos sectores clave en América Latina y el Caribe, como por ejemplo el sector turístico.  La Organización Mundial del Turismo (OMT) considera que la concurrencia de turistas internacionales a nivel mundial disminuyó entre 58% y 78% en 2020 (CEPAL, 2020), lo que hace presumir que la reactivación del sector sea progresiva en el 2021. Uno de los países que padeció el aumento descontrolado y progresivo de contagios del SARS-CoV-2 fue Ecuador, registrándose más de 2,758 contagios y 98 muertes confirmadas en los primeros meses de la pandemia, ocupando el segundo lugar en muertes después de Brasil (Millan, 2020).  La investigación tiene por objetivo analizar el impacto social y económico que ha enfrentado el cantón Playas, uno de los principales lugares turísticos de la provincia del Guayas-Ecuador, para lo cual se aplicó el siguiente método: i) Análisis de los indicadores socio-económicos aplicados al sector turístico nacional e internacional, ii) Análisis del caso de estudio y aplicación de encuestas a centros turísticos del cantón Playas en dos momentos, y, iv) Inferencias sobre indicadores afectados. Los resultados obtenidos conllevan a reflexionar si la mala situación que atraviesa el sector turístico ecuatoriano es el resultado de la pandemia o de política pública.

Los bosques secos en Ecuador son ecosistemas diversos muy preciados, pero presionados por actividades antropogénicas que alteran su composición, estructura y dinámica. El objetivo del presente trabajo fue analizar la estructura y condiciones abióticas del bosque seco tropical del sector La Pila Vieja en el valle Sancán, Manabí, Ecuador. Se registró el diámetro y altura de individuos mayores a 5 cm en parcelas de 0.10 ha validadas por la curva área-especie; se calcularon los índices de valor de importancia ecológica, Simpson, Shannon y estructura diamétrica. Se registraron 336 individuos que pertenecen a 31 especies dentro de 28 géneros y 15 familias. Las familias con mayor número de especies fueron: Fabaceae, Boraginaceae, Rutaceae, Moraceae y Sapindaceae. Las especies de mayor importancia ecológica detectadas: Ceiba trichistandra, Bursera graveolens, Leucaena trichoides y Mauria heterophylla. Según el índice de Shannon, la diversidad fue alta (3.72). Las variables abióticas relacionadas con la abundancia de especies explicaron el ordenamiento espacial de forma satisfactoria y explicaron el 97.40% de la relación especie-variables abióticas. Las especies encontradas son representativas del bosque seco tropical con intervención antropogénica de uso selectivo y sin planificación técnica, influenciada por variables abióticas tales como: materia orgánica, pH y potasio, que condicionan su distribución.
Altitude and Distance Relationships with the Multidimensional Poverty Index: The case of Peru
Authors: Delgado Augusto
Published: August 2023

This paper studies the potential association between two geographic indicators, distance and altitude, with the Multidimensional Poverty Index (MPI) for 1,874 district in Peru by using the National Census of 2017. We investigate whether higher altitude or longer distance is associated with higher MPI values. For this purpose, we use the distance of each district to three different potential spaces of reference. First, we use the shortest distance to the metropolitan area of Lima; second, the shortest distance to the capitals of coastal departments; third, and finally, the shortest distance to the sea. We obtain three relevant results. First, we find evidence that altitude is statistically significant and positive associated with variation of MPI among districts. Second, the distance with respect to the sea appears to be more relevant to explaining differences in MPI than the distance to the Metropolitan area or coastal departmental capitals. Finally, we find evidence of spatial externalities of MPI across districts which also seem to be stronger than the direct effect of altitude and distance.

Research examining small commercial and industrial electricity usage patterns have historically received less attention than residential electricity consumption patterns. This study examines electricity as an input to small firm commercial and industrial (CIS) production in Las Cruces, the second largest metropolitan economy in the state of New Mexico, using annual frequency data from 1978 to 2018. Those data include labor, per capita personal income, price measures for electricity and natural gas, and weather variables. The long-run and short-run elasticities of the data are then estimated using an autoregressive distributed lag model (ARDL). In the long-run, the CIS derived-demand curve is found to be upward sloping, and Las Cruces CIS customers use natural gas as a complementary input. Real per capita income is also found to have a positive impact in the long-run, while weather impacts are found to be ambiguous. In the short-run, the Las Cruces CIS derived-demand curve is downward sloping, CIS customers use natural gas as a substitute factor, and weather extremes are found to be positively correlated with small firm electricity usage.

PORCOS SOBERANOS
Authors: FUÃO FERNANDO
Published: August 2023

Estranho, muito estranho porcos serem soberanos, embora seja frequente ao longo da História encontrar-se soberanos porcos. De entrada, convidado a retirar e desconstruir todo o preconceito imputado pela sociedade aos tristes porcos como animais que vivem e comem seus excrementos e se chafurdam na lama. Chafurdam-se e comem seus excrementos somente porque estão aprisionados em seus chiqueiros, porque foram domesticados; caso contrário, libertos estariam vagando pelos bosques afora catando raízes, trufas, e chafurdando na lama para protegerem suas peles. A passo de lobo, como propôs Derrida em seu seminário A besta e o Soberano I, vamos descobrir nessa fábula que sob a pele de porco dormita os soberanos domesticadores.
A MÍMESE NA ANTIGUIDADE
Authors: BORGES CAROLINA
Published: August 2023

: A Antiguidade possui a natureza como referência para o belo e a arte era criada a partir da mimese. A natureza poderia ser copiada tanto na sua forma literal como também na sua gênese. Para isso, existiam postulados que estruturavam as obras a parir da geometria, proporção e consonância entre as partes, que Vitrúvio vai chamar de simetria. Posteriormente, os antigos passaram a valorizar uma beleza mais intuitiva e menos calculada, marcada pela eurritmia. Esta possui elementos que expressam características propriamente humanas, gerando uma relação de identificação e reconhecimento com o receptor.
MANGÁS – HISTÓRIAS EM QUADRINHOS DA TERRA DO SOL NASCENTE
Authors: DO CARMO ALVARENGA MARCOS AURÉLIO
Published: August 2023

Os Mangás são as histórias em quadrinhos nipônicas que buscam retratar desde narrativas cotidianas da população japonesa, as mais diversas histórias fantásticas que a imaginação possibilitar criar. O objetivo desta pesquisa foi realizar um levantamento histórico das influências que deram origem a esse tipo específico de história em quadrinho, buscando compreender assim as características que definiram a singularidade que é representada pelos mangás na contemporaneidade. Por apresentar características singulares, os mangás por muitos não é reconhecido como uma história em quadrinho, ainda por apresentar uma maior influência nipônica, caracterizado pelas expressões artísticas japonesas (e-makimono e ukiyo-ê), porém, ao compreender algumas características com relação a suas apresentações estéticas, vemos não só um aparecimento de uma nova forma de se conceber as histórias em quadrinhos, como também um tipo de arte sequencial que apresentar a junção de diversos elementos inerentes às artes japonesas e estadunidenses, dando assim origem aos mangás como conhecemos na atualidade.
SEU NOME GRAVADO EM MIM
Authors: FARIAS MENTOR PEDRO
Published: August 2023

O seguinte ensaio é uma tentativa de pensar os conceitos de precariedade e enquadramento, como desenvolvidos pela filósofa estadunidense Judith Butler, aplicados à ideia de amor. Partimos da forma como a heterossexualidade, enquanto um regime político, é capaz de determinar as condições e os mecanismos de reconhecimento e inteligibilidade do amor sob os ditames de sua lógica binária para pensar como ele é socialmente moldado e tensionado. O filme taiwanês Seu Nome Gravado em Mim e seu contexto serão usados como forma de apresentar essas ideias numa linguagem mais concreta. Finalizamos com um aceno para a possibilidade do amor assombroso oferecer outros caminhos que aqueles estreitados pelo amor hetero.
HISTÓRIA E ORIGEM DO GUARÁ NO CORREIO BRAZILIENSE
Authors: FERRARINI VENTURELLI LUIS GUSTAVO
Published: August 2023

O artigo apresenta uma análise histórica do surgimento da cidade do Guará no Distrito Federal, narrado nas páginas do jornal Correio Braziliense no fim da década de 60. O objetivo é analisar as narrativas criadas nas páginas do jornal sobre a cidade que virá a ser o Guará e como essa história acaba em uma representação de sucesso da “revolução” nas páginas do jornal. A origem da cidade se deu com o nome de Mutirão da Novacap, como um assentamento voltado a trabalhadores da Novacap, do Setor de Indústria e Alimentação, em função de problemas de moradia da nova capital. O Guará é resultado do processo de transformação de um assentamento na cidade. Essa mudança de status serviu ainda como propaganda nas páginas do Correio Braziliense. Seguindo os passos de Maria Helena Rolim Capelato, nos servimos dos jornais como fonte, para desvelar o ideário descrito em suas páginas quanto a historicidade presente na formação da cidade. Por fim, buscamos discutir o contexto do surgimento da cidade de modo a perceber como foram assentados os seus moradores, perceber se esse foi o mesmo modelo de ocupação habitacional da capital, e finalmente a propaganda feita à época da inauguração do Guará nas páginas desse jornal.

The World Health Organization (WHO) states that the top ten causes of death and illness worldwide are caused by occupational risks. In Indonesia itself in 2005, the Ministry of Health of the Republic of Indonesia stated that as many as 16% of workers had musculoskeletal complaints. The workers every day always do the same work and repeat from day to day, so it is feared that in the long term their health will be disturbed. Quoted from the Central Statistics Agency, the number of industrial sectors in DIY contributed 11.97% to regional income. One of the industrial companies in the Special Region of Yogyakarta (DIY) is PT Mega Andalan Kalasan (MAK). This research was conducted at PT Mega Andalan Kalasan (PT MAK) with a descriptive type of research. The potential for ergonomic hazards at PT Mega Andalan Kalasan (PT MAK) is a source of potential losses arising from the concept of work attitude, work station layout. Where this ergonomic hazard has the potential to occur to all workers at PT MAK without any difference in treatment. The potential hazards of ergonomics based on aspects of work attitude are found in the finishing process (fireplace and wheel refinement and small parts).

Health for all is the goal of sustainable health development as a form of joint investment, commitment to improve the quality of life and the health status of the community as high as possible, according to the mandate of UU RI Number 36 of 2009. Portraits of the complexity of national health problems are also found in DIY, one of the provinces that has been privileged with the enactment of Law No. 13 of 2012 concerning the privileges of the Special Region of Yogyakarta (DIY). The purpose of this study is to photograph health financing in DIY and its utilization. This study uses a descriptive research method with literature review from various references (Library Research) to analyze DIY health financing policies in 2021. The results of the study show that the life expectancy of DIY reached 74.92% in 2019 and became the best nationally, but on the other hand the poverty rate is also very high compared to the national figure so that the potential for vulnerability to disease and financial resilience is low when there is no health insurance from the government. , the portion of the health budget in DIY of 6.6% is still less than the mandate of the Health Law of 10% of the total APBD, and the specialty of DIY has Danais that distinguishes it from other provinces in Indonesia, although the portion of Danais is smaller but its allocation can be maximized to support efforts to increase public health status.
