COMPUTATIONAL DESIGN FOR THE PRESERVATION AND ENHANCEMENT OF HISTORICAL HERITAGE. A PREFABRICATED COVERING PROTOTYPE FOR ARCHAEOLOGICAL SITES IN RURAL CONTEXT
No full textIn Italy, many archaeological sites in peri-urban and rural areas are in a deep state of neglect, with unprotected remains and no prospects of enhancement. The paper shows the results of a study aimed at developing a parametric prototype of a prefabricated coverage, to be adapted to various conditions. The Roman Domus of the Acropolis of Populonia in the archaeological park of Baratti and Populonia in Tuscany was chosen as case study. The prototype was parametrically realized using heuristic algorithms based on natural selection (Genetic Algorithms), associated with multi-objective optimization criteria.
The algorithm was conceived to optimize the support pillars’ position and the visiting path, in relation to the main points of interest of the archaeological site. The final product consists of a wooden structural covering with 11 steel circular-section pillars, completed with a casing made of wood slats and opaque white PVC sheets
Imaginación documental : los ensamblajes fotográficos de Kenzo Tange, Kazuo Shinohara y Kazuyo Sejima (1954-2004)
No full textVivimos envueltos por una red de imágenes. Desde lo más íntimo y personal a lo más anodino o institucional, la imagen técnica media y se infiltra en todas las capas de nuestro día a día. Nos promete inmediatez al tiempo que nos oculta —con sigilo, casi sin que nos demos cuenta— sus sutiles efectos y desplazamientos... y la arquitectura no es ajena a esta dinámica.
Esta tesis estudia el papel que juega la imagen fotográfica en la renovación de los imaginarios de la domesticidad en Japón durante la segunda mitad del siglo XX. Investiga los viajes de ida y vuelta entre unas arquitecturas físicas y otras virtuales: las primeras construidas en piedra, papel y madera —vidrio, metal y hormigón después— y las segundas imaginadas a partir de algunas lentes, emulsiones y mucha tinta sobre el papel: meros calcos o copias o recortes discretos de lo físico que tienden a viajar y a juntarse con otros formando agregados o imágenes-libro. Fanzines, fotolibros y revistas que proliferan por doquier tras la Segunda Guerra Mundial en Japón articulando discursos, agitando conciencias y movilizando audiencias.
Se parte de una doble hipótesis. Primero que estos fanzines, fotolibros y revistas no son simples almacenes, depósitos o repositorios pasivos sino herramientas proyectuales activas que operan como un atlas; “como mesas de orientación y montaje,” en palabras de Didi-Huberman. Y segundo que estos atlas no operan en el vacío, sino respondiendo a las lógicas y mecanismos descritos por la doble economía del archivo de Boris Groys: la economía de la innovación —que rige los intercambios entre el espacio del archivo y el mundo de lo profano— y la economía de la sospecha —que describe la tensa relación cuasi-paranoica entre espectador, medio y autor.
Sobre esta base se analiza el recorte y desmontaje de Katsura de Kenzo Tange y Yasuhiro Ishimoto a finales de la década de 1950 la fotografía en marcha o accidental de los fanzines de los sesenta y su relación con el trabajo de Kazuo Shinohara y Koji Taki a principios de la década de 1970 y por último la imagen electrónica y el composite digital en los trabajos de Toyo Ito, los fotolibros de Takashi Homma y Walter Niedermayr y los libros, imágenes y arquitecturas de Kazuyo Sejima a finales de la década de 1990 y principios de los 2000. Tres sucesivas lógicas de montaje —patrones, patchworks y pantallas— que terminan por extrañar, renovar y entremezclar ambos: el imaginario de la casa y la imaginación de la ciudad.
ABSTRACT
We live surrounded by a seamless web of images. From the most private and personal, to the more anodyne or institutional, the thechnical image mediates and infiltrates all layers of our daily life. It promises us immediacu while concealing —stealthy and almost unnoticed— its subtle effects and displacements... and architecture is no stranger to this dynamic.
This thesis explores the role played by the photographic image in the renewal of the domesticity imagination in Japan during the second half of the twentieth century. It investigates the travels back and forth between physical and virtual architectures: the former built in stone, paper and wood —glass, metal and concrete, after that— and the latter imagined from a few lenses, emulsions and a lot of ink on paper: mere cut-outs or discrete tracings of the physical, that tend to travel and join forces with others building aggregates or book-images. Fanzines, photobooks and magazines that proliferate everywhere after World War II in Japan, articulating discourses, shaking consciences and mobilizing audiences.
The hypothesis is twofold. First, that these fanzines, photobooks and magazines are not simple passive warehouses, deposits or repositories but active projectual tools that operate as an atlas; “as orientation and assembly tables,” in Didi-Huberman’s words. And second, that these atlases do not operate in a vacuum, but responding to the logics and mechanisms described by Boris Groys’ double economy of the archive: the economy of innovation —which governs the exchanges between the space of the archive and the world of the profane — and the economy of suspicion —which describes the tense, quasi-paranoid relationship between spectator, medium and author.
On this basis, we analyze Kenzo Tange and Yasuhiro Ishimoto’s cropping and dismantling of Katsura in the late 1950s; the on-the-move or accidental photography of 1960s Provoke fanzines, and its relationship to the work of Kazuo Shinohara and Koji Taki in the early 1970s; and finally the electronic image and digital composites in the work of Toyo Ito, the photobooks of Takashi Homma and Walter Niedermayr and their relationship to the books, images and architectures of Kazuyo Sejima, in the late 1990s and early 2000s. Three successive logics of montage —patterns, patchworks and screens— that end up estranging, renewing and intermingling both: the imaginary of the house and the imagination of the city

Variabilidad de las mediciones antropométricas obtenidas por protocolo ISAK y bioimpedancia en usuarios de un gimnasio, Trujillo 2023
No full textEl presente estudio tuvo como finalidad analizar la variabilidad de las mediciones
antropométricas obtenidas a través de dos métodos distintos, el protocolo ISAK y
la bioimpedancia, en usuarios de un gimnasio en Trujillo durante 2023. Tuvo un
diseño no experimental de corte transversal de tipo aplicado; la muestra estuvo
constituida por 58 usuarios, tanto hombres como mujeres, mayores de 18 años.
Para evaluar la composición corporal, se aplicaron dos técnicas de medición: la
antropometría basada en el protocolo ISAK nivel I y la bioimpedancia utilizando un
dispositivo OMRON HBF-514C. Se usó la prueba de Chi cuadrado para identificar
diferencias significativas entre los métodos y el análisis de T-Student para verificar
la homogeneidad en las varianzas de las variables. Los resultados revelaron una
asociación significativa (P<0,00) y una correlación positiva moderada (r = 0,639)
entre las mediciones de porcentaje de grasa por ISAK y bioimpedancia, así como
una asociación altamente significativa (P<0,00) y una correlación positiva fuerte (r
= 0,721) para el porcentaje de músculo. Existe una relación altamente significativa
y positiva entre ambas metodologías de medición, lo que sugiere que estos
métodos son consistentes y confiables para evaluar la composición corporal en esta
población de usuarios de gimnasio

No full textA systematic review of evidence on malignant spinal metastases : natural history and technologies for identifying patients at high risk of vertebral fracture and spinal cord compression
No full textBackground: Spinal metastases can lead to significant morbidity and reduction in quality of life due to spinal cord compression (SCC). Between 5% and 20% of patients with spinal metastases develop metastatic spinal cord compression during the course of their disease. An early study estimated average survival for patients with SCC to be between 3 and 7 months, with a 36% probability of survival to 12 months. An understanding of the natural history and early diagnosis of spinal metastases and prediction of collapse of the metastatic vertebrae are important.
Objective: To undertake a systematic review to examine the natural history of metastatic spinal lesions and to identify patients at high risk of vertebral fracture and SCC.
Data sources: The search strategy covered the concepts of metastasis, the spine and adults. Searches were undertaken from inception to June 2011 in 13 electronic databases [MEDLINE; MEDLINE In-Process & Other Non-Indexed Citations; EMBASE; Cochrane Database of Systematic Reviews; Cochrane Central Register of Controlled Trials (CENTRAL); Database of Abstracts of Reviews of Effects (DARE), NHS Economic Evaluation Database (NHS EED), HTA databases (NHS Centre for Reviews and Dissemination); Science Citation Index and Conference Proceedings (Web of Science); UK Clinical Research Network (UKCRN) Portfolio Database; Current Controlled Trials; ClinicalTrials.gov].
Review methods: Titles and abstracts of retrieved studies were assessed by two reviewers independently. Disagreement was resolved by consensus agreement. Full data were extracted independently by one reviewer. All included studies were reviewed by a second researcher with disagreements resolved by discussion. A quality assessment instrument was used to assess bias in six domains: study population, attrition, prognostic factor measurement, outcome measurement, confounding measurement and account, and analysis. Data were tabulated and discussed in a narrative review. Each tumour type was looked at separately.
Results: In all, 2425 potentially relevant articles were identified, of which 31 met the inclusion criteria. No study examined natural history alone. Seventeen studies reported retrospective data, 10 were prospective studies, and three were other study designs. There was one systematic review. There were no randomised controlled trials (RCTs). Approximately 5782 participants were included. Sample sizes ranged from 41 to 859. The age of participants ranged between 7 and 92 years. Types of cancers reported on were lung alone (n= 3), prostate alone (n= 6), breast alone (n= 7), mixed cancers (n= 13) and unclear (n= 1). A total of 93 prognostic factors were identified as potentially significant in predicting risk of SCC or collapse. Overall findings indicated that the more spinal metastases present and the longer a patient was at risk, the greater the reported likelihood of development of SCC and collapse. There was an increased risk of developing SCC if a cancer had already spread to the bones. In the prostate cancer studies, tumour grade, metastatic load and time on hormone therapy were associated with increased risk of SCC. In one study, risk of SCC before death was 24%, and 2.37 times greater with a Gleason score 7 than with a score of < 7 (p= 0.003). Other research found that patients with six or more bone lesions were at greater risk of SCC than those with fewer than six lesions [odds ratio (OR) 2.9, 95% confidence interval (CI) 1.012 to 8.35, p= 0.047]. For breast cancer patients who received a computerised tomography (CT) scan for suspected SCC, multiple logistic regression in one study identified four independent variables predictive of a positive test: bone metastases 2 years (OR 3.0 95% CI 1.2 to 7.6; p= 0.02); metastatic disease at initial diagnosis (OR 3.4, 95% CI 1.0 to 11.4; p= 0.05); objective weakness (OR 3.8, 95% CI 1.5 to 9.5; p= 0.005); and vertebral compression fracture on spine radiograph (OR 2.6, 95% CI 1.0 to 6.5; p= 0.05). A further study on mixed cancers, among patients who received surgery for SCC, reported that vertebral body compression fractures were associated with presurgery chemotherapy (OR 2.283, 95% CI 1.064 to 4.898; p= 0.03), cancer type [primary breast cancer (OR 4.179, 95% CI 1.457 to 11.983; p= 0.008)], thoracic involvement (OR 3.505, 95% CI 1.343 to 9.143; p= 0.01) and anterior cord compression (OR 3.213, 95% CI 1.416 to 7.293; p= 0.005).
Limitations: Many of the included studies provided limited information about patient populations and selection criteria and they varied in methodological quality, rigour and transparency. Several studies identified type of cancer (e.g. breast, lung or prostate cancer) as a significant factor in predicting SCC, but it remains difficult to determine the risk differential partly because of residual bias. Consideration of quantitative results from the studies does not easily allow generation of a coherent numerical summary, studies were heterogeneous especially with regard to population, results were not consistent between studies, and study results almost universally lacked corroboration from other independent studies.
Conclusion: No studies were found which examined natural history. Overall burden of metastatic disease, confirmed metastatic bone involvement and immediate symptomatology suggestive of spinal column involvement are already well known as factors for metastatic SCC, vertebral collapse or progression of vertebral collapse. Although we identified a large number of additional possible prognostic factors, those which currently offer the most potential are unclear. Current clinical consensus favours magnetic resonance imaging and CT imaging modalities for the investigation of SCC and vertebral fracture. Future research should concentrate on: (1) prospective randomised designs to establish clinical and quality-of-life outcomes and cost-effectiveness of identification and treatment of patients at high risk of vertebral collapse and SCC; (2) Service Delivery and Organisation research on magnetic resonance imaging (MRI) scans and scanning (in tandem with research studies on use of MRI to monitor progression) in order to understand best methods for maximising use of MRI scanners; and (3) investigation of prognostic algorithms to calculate probability of a specified event using high-quality prospective studies, involving defined populations, randomly selected and clearly identified samples, and with blinding of investigators
