The uncontrolled friction stir welding heat generation impacts the quality of welds. However, the intuition and experience of the engineer fail to regulate the effects of excessive heat generation on the weld quality and research has not addressed this aspect yet. This paper fills the gap by introducing an integrated CRITIC-BPNN (CRiteria Importance Through Intercriteria Correlation-Back Propagation Neural Network) method to investigate the selection and optimisation characteristics of the friction stir welding process for AA6082-T6 material. In this study, two major performance characteristics i.e. ultimate tensile strength (UTS) and percentage elongation (%EL), were chosen for analysis. The input parameters for the machining were the tool rotational speed, welding speed, tool pin profile and tool shoulder diameter. For the back propagation neural network model, a four-layer network with sigmoid hidden neurons and output neurons was selected. The weight estimates of the friction stir welding parameters are determined by the CRITIC method. For further weight determination between the nodes and edges of the neural networks, the Poisson distribution model was introduced. This stochastic-based method was used to calculate the weights at the edges, between the inputs, hidden layers and outputs of the neural network. The forward pass and backward passes are then used for updating and error minimisation. The welding speed has the highest weight with a contribution of 49.72% using the CRITIC method, implying that welding speed is the best and most influential parameter of the friction stir welding process. For the 4-1-2 neural network architecture, the values of the ultimate tensile strength and percentage elongation at the optimal thresholds are 0.6457 and 0.6019, respectively, for the first forward pass and 0.6123 and 0.6356, respectively, for the second forward pass. The predicted tensile strength is 320.64 MPa and the prediction for the percentage elongation is 18.83%. The results obtained from the proposed method could be useful for planning purposes during the friction welding process.
DETECTION OF KERATOCONUS DISEASE DEPENDING ON CORNEAL TOPOGRAPHY USING DEEP LEARNING
Authors: Hasan Aseel , Mazinani Mahdi 
Published: February 2025

Keratoconus is a disease that ML has contributed much in its diagnosis and management. It is not a widely prevalent disease, with a research gap caused by the absence of standardized datasets for model training and evaluation. This work presents a novel dataset, which strengthens the CNN model's resilience and creates standards for assessing keratoconus diagnostic techniques. The research depends on data of patients examined at Jenna Ophthalmic Center in Baghdad. The proposed system works on three stages: pre-processing, feature extraction, and classification with machine learning algorithms including NB, KNN, ADA, DT, and CNN deep learning. The pre-processing stage involves cropping images to retain the relevant maps, which were subjected to contrast enhancement to improve image quality. The pre-processed data is then fed into Machine Learning(ML) algorithms and Convolutional Neural Network(CNN) models, by which the four corneal maps were analyzed. The precision of the ML method was quantified, yielding a precision score of 0.79 for the AdaBoost algorithm and an impressive score of 0.99 for the suggested CNN model exemplifying its high accuracy and ability to surpass all machine learning approaches. Applying PCA for feature extraction before utilizing tradition ML algorithms and CNN helps in achieving high-accuracy results.

Abstract The global economy has suffered as a result of the COVID-19 health crisis, particularly the travel and tourism industry. The COVID-19 pandemic has caused major losses for the tourism industry. However, as the impact of COVID-19 decreases, current tourism behavior causes the possibility of overtourism. Over the past few years, the desire for “revenge tourism” has increased as a result of negative feelings caused by the COVID-19 pandemic. Excessive tourism also has a negative social impact from a psychological point of view, but from a psychological point of view, it may be due to negative emotions accumulated over a period of time. Bali is also facing poor sustainable tourism development after the drastic economic decline caused by the COVID-19 pandemic. With the excessive increase in the number of tourists, will this have a negative impact on sustainable tourism development in Bali? This research was created to find out whether the overtourism that is being rumored will have an impact on workers for tourism development in Bali after the COVID-19 pandemic occurred several years ago.

Published: February 2025

This study evaluates the effectiveness of the Republic Tani Mandiri (RTM) social business program using the Social Return on Investment (SROI) approach. The research focuses on the RTM Coffee Farmers Group, an initiative in coffee agriculture. A mixed-method approach with a subsequential exploratory design was employed. The analysis reveals that an initial investment of IDR 279,756,965 has not yet yielded positive short-term results, with an SROI ratio of 1:0.25. This indicates that each IDR 1 invested generates a social, economic, and environmental impact valued at IDR 0.25. Although this ratio is lower than anticipated, the program’s social and economic impacts remain significant. Positive changes were observed among coffee farmers in Desa Kucur, who experienced improved coffee quality and selling prices with support from Universitas Ma Chung. However, to ensure sustained benefits, ongoing support and strategic adjustments are necessary. The findings are expected to encourage continued support for similar initiatives in the future.

MARCADORES GRÁFICOS Y TERRITORIOS TRADICIONALES EN LA PREHISTORIA DE LA PENÍNSULA IBÉRICA
Authors: Bueno Ramírez Primitiva , De Balbín Behrmann Rodrigo 
Published: February 2025

La estrecha relación entre la posición de las grafías y los territorios económicos de los grupos que las produjeron se constata diacrónicamente. El mundo de los cazadores paleolíticos no es sólo el de la oscuridad de las cavernas, sino el de sierras, valles y ríos al aire libre cuyas referencias simbólicas han quedado grabadas y pintadas en soportes rocosos. Son ellos los pioneros en la definición gráf ica de los lugares que forman parte de su universo cotidiano. La recurrencia en la decoración de los mismos enclaves tiene su constatación con la presencia de grafías postpaleolíticas. Presenta los grandes yacimientos al aire libre como la visualización de territorios tradicionales, aquéllos cuya delimitación se conoce por formar parte del grupo, y cuyo tránsito y uso está asegurado por los símbolos de los ancestros.
LAS DOMUS DE JANAS SARDAS. PROYECCIÓN DE LA “RELIGIÓN” Y PROYECCIÓN DE LA ESTABILIDAD
Authors: Spanedda Liliana 
Published: February 2025

Este trabajo pretende señalar que las representaciones animales de las domus de janas y la decoración arquitectónica reconocida en este tipo de tumbas mantienen una relación más estrecha de lo que hasta ahora se ha sugerido, trascendiendo un hipotético significado “religioso”. Se señala la posibilidad de la presencia de este tipo de representaciones, o los “trofeos” de los que derivarían, en las viviendas, comunes o especiales, que formaron el modelo y el complemento de estas tumbas. Además la presencia de estas figuras animales estaría relacionada con el papel de determinadas especies en la acumulación de riqueza y en su exhibición, en su uso como medio de producción, independientemente de su posible divinización en uno u otro momento como consecuencia de este mismo papel, como símbolo de sus propietarios, y del uso de la Ideología en la justificación de un determinado tipo de sociedad.

EL LABOREO DEL COBRE EN LA SIERRA DEL ARAMO (ASTURIAS) COMO REFERENTE CARDINAL DE LA MINERÍA PREHISTÓRICA EN LA REGIÓN CANTÁBRICA
Authors: De Blas Cortina Miguel Ángeles 
Published: February 2025

La minería prehistórica del cobre cuenta con cuatro distritos bien establecidos en el sector norte peninsular: tres en el espacio astur-leonés y el cuarto en Guipúzcoa. De todos ellos es el de la sierra del Aramo (Asturias) el más notable por la extraordinaria variedad de información que vino aportando. Las investigaciones de campo reiniciadas en 2005 no sólo enriquecen y precisan lo ya establecido sino que abren amplias y variadas perspectivas al proceso minero, a su amplitud física y extensión cronológica, a las técnicas laborales y medios instrumentales. La localización reciente de áreas de actividad cerca de las explotaciones documenta tanto las actividades campamentales —vestigios de los asentamientos estivales de los prospectores a 1.100 metros de altitud—, como un primer proceder metalúrgico al que se asocian las pri- meras cerámicas campaniformes conocidas en el cantábrico centro-occidental. La cuantiosa presencia de esqueletos humanos en las galerías prehistóricas constituye además la posibilidad de vislumbrar algunas creencias de los mineros, en particular la probable comprensión de su trabajo como el expolio de bienes subterráneos.
LA ZONA MINERA DE S’ARGENTERA, ISLA DE IBIZA (ISLAS BALEARES)
Authors: Hermanns Marcus Heinrich 
Published: February 2025

El objetivo del proyecto arqueominero iniciado en el año 2010 es realizar un estudio diacrónico de la minería de la galena argentífera en la isla de Eivissa/Ibiza. Con este fin se llevaron a cabo diversas campañas de prospección y se realizó un reconocimiento topográf ico del yacimiento minero de s’Argentera en el nordeste de la isla. El proyecto tiene además otro enfoque, que consiste en identif icar la signatura del yacimiento minero a través de pruebas del material y de su análisis químico e isotópico, para así compararlo con los análisis del material de plomo / plata presente en objetos con clara procedencia arqueológica, sobre todo objetos datados y con una estratigrafía. A través de los resultados analíticos y arqueológicos del terreno será posible en un futuro próximo hacer un planteamiento cronológico-histórico de la minería ibicenca en la Antigüedad y determinar el papel que jugaba la isla dentro de las redes comerciales del Mediterráneo occidental, no solo como punto de apoyo y de (re)distribución de productos sino también como productora de recursos, en este caso mineros, propios.
LAS CERÁMICAS IBÉRICAS CON DECORACIÓN ESTAMPILLADA DEL CERRO DE LA CRUZ (ALMEDINILLA, CÓRDOBA)

Published: February 2025

Presentamos un catálogo, análisis y estudio cronológico y espacial de las cerámicas ibéricas con decoración estampillada procedentes del poblado ibérico del Cerro de la Cruz (Almedi- nilla), uno de los muy pocos en Andalucía excavados en extensión. Procedentes normalmente de niveles superf iciales y muy fragmentadas, al contrario de lo que es normal en las estancias de este poblado destruido violentamente hacia 141 a.C., es posible que estas piezas formen parte de una fase ligeramente más antigua al nivel de destrucción y con vinculaciones con el área de Jaén e incluso la Submeseta Sur.

Pengembangan Pariwisata Berbasis Penataan Ruang di Pulau Tidung Besar Kepulauan Seribu
Authors: Kasman Kasman , Martha Taufik Leo , Johan Yar 
Published: February 2025

Pulau Tidung Besar memiliki keindahan pantai dan keanekaragaman flora dan fauna laut yang menjadikan pulau ini menjadi salah satu destinasi wisata yang ramai dikunjungi oleh wisatawan domestik dan mancanegara. Seperti umumnya sebuah pulau, Pulau Tidung Besar memiliki luas wilayah yang kecil, sehingga dalam pengembangan pariwisata harus memperhatikan aspek penataan ruang agar dapat optimal dan berkesinambungan. Tujuan penelitian ini adalah merumuskan konsep pengembangan pariwisata di Pulau Tidung Besar, Kabupaten Kepulauan Seribu, Provinsi DKI Jakarta melalui analisis amenitas wisata, atraksi wisata, analisis faktor yang mempengaruhi kunjungan wisatawan dan analisis daya dukung kawasan wisata, dengan pendekatan spasial. Hasil penelitian menunjukkan bahwa terdapat ketidaksesuaian kegiatan pemanfaatan ruang sebesar 7% (4,2 ha) pada area sempadan pantai, eksistensi bangunan melebihi nilai batas intensitas bangunan yang ditetapkan (KDB 36%) dan area akomodasi wisata telah melebihi kebutuhan wisatawan (3.640 m2). Kondisi ini disebabkan ketidakpahaman masyarakat terhadap penataan ruang dan lemahnya perencanaan dan pengendalian pemanfaatan ruang. Kondisi tata ruang Pulau Tidung Besar sudah tidak sesuai dengan kondisi perkembangan pulau, sehingga diperlukan peninjauan kembali terhadap RDTR yang berorientasi pada peningkatan pengendalian tata ruang untuk pengembangan pariwisata yang lebih baik. Penelitian ini dapat menjadi referensi bagi pengembangan pariwisata di pulau kecil dengan mengatur pola pemanfaatan ruang yang terbatas.
