L'utililizzo delle ICT nel processo penale

Il progetto di ricerca si situa nell’ambito dell’informatica giudiziaria settore che studia i sistemi informativi implementati negli uffici giudiziari allo scopo di migliorare l’efficienza del servizio, fornire una leva per la riduzione dei lunghi tempi processuali, al fine ultimo di garantire al meglio i diritti riconosciuti ai cittadini e accrescere la competitività del Paese. Oggetto di studio specifico del progetto di ricerca è l’utilizzo delle ICT nel processo penale. Si tratta di una realtà meno studiata rispetto al processo civile, eppure la crisi di efficienza del processo non è meno sentita in tale area: l’arretrato da smaltire al 30 giugno del 2011 è stato quantificato in 3,4 milioni di processi penali, e il tempo medio di definizione degli stessi è di quattro anni e nove mesi. Guardare al processo penale con gli occhi della progettazione dei sistemi informativi è vedere un fluire ininterrotto di informazioni che include realtà collocate a monte e a valle del processo stesso: dalla trasmissione della notizia di reato alla esecuzione della pena. In questa prospettiva diventa evidente l’importanza di una corretta gestione delle informazioni: la quantità, l’accuratezza, la rapidità di accesso alle stesse sono fattori così cruciali per il processo penale che l’efficienza del sistema informativo e la qualità della giustizia erogata sono fortemente interrelate. Il progetto di ricerca è orientato a individuare quali siano le condizioni in cui l’efficienza può essere effettivamente raggiunta e, soprattutto, a verificare quali siano le scelte tecnologiche che possono preservare, o anche potenziare, i principi e le garanzie del processo penale. Nel processo penale, infatti, sono coinvolti diritti fondamentali dell’individuo quali la libertà personale, la dignità, la riservatezza, diritti fondamentali che vengono tutelati attraverso un ampia gamma di diritti processuali quali la presunzione di innocenza, il diritto di difesa, il diritto al contraddittorio, la finalità di rieducazione della pena.

Riabilitazione del mascellare posteriore atrofico mediante impianti corti (6-8 mm) o rialzo di seno con contestuale inserimento di impianti di lunghezza standard: studio retrospettivo con follow up a 3 anni

Background: sebbene la letteratura recente abbia suggerito che l’utilizzo degli impianti corti possa rappresentare una alternative preferibile alle procedure di rigenerazione ossea nelle aree posteriori atrofiche, perché è un trattamento più semplice e con meno complicazioni, esistono solo pochi studi a medio e lungo termine che abbiano comparato queste tecniche. Scopo: lo scopo di questo studio retrospettivo è quello di valutare se gli impianti corti (6-8 mm) (gruppo impianti corti) possano presentare percentuali di sopravvivenza e valori di riassorbimento osseo marginali simili a impianti di dimensioni standard (≥11 mm) inseriti contemporaneamente ad una grande rialzo di seno mascellare. Materiali e Metodi: in totale, 101 pazienti sono stati inclusi: 48 nel gruppo impianti corti e 53 nel gruppo seno. In ciascun paziente da 1 a 3 impianti sono stati inseriti e tenuti sommersi per 4-6 mesi. I parametri clinici e radiografici valutati sono: i fallimenti implantari, le complicazioni, lo stato dei tessuti molli, e il riassorbimento osseo marginale. Tutti i pazienti sono stati seguiti per almeno 3 anni dal posizionamento implantare. Risultati: il periodo di osservazione medio è stato di 43.47 ± 6.1 mesi per il gruppo impianti corti e 47.03 ± 7.46 mesi per il gruppo seno. Due su 101 impianti corti e 6 su 108 impianti standard sono falliti. Al follow-up finale, si è riscontrato un riassorbimento osseo medio di 0.47 ± 0.48 mm nel gruppo impianti corti versus 0.64 ± 0.58 mm nel gruppo seno. Non sono presenti differenze statisticamente significative fra i gruppi in termini di fallimenti implantari, complicazioni protesiche, tessuti molli, e riassorbimento osseo. Il gruppo seno ha presentato, invece, un maggior numero di complicazioni chirurgiche. Conclusioni: entrambe le tecniche hanno dimostrato un simile tasso di successo clinico e radiografico, ma gli impianti corti hanno ridotto il numero di complicazioni chirurgiche.

[Does the combination syndrome exist? A case report]

This case report documents the prosthetic rehabilitation of a patient showing the typical features of combination syndrome. This case documentation gives a general overview of the suspected development and the prevalence of this "syndrome". A treatment option should be shown by the example of a patient from the starting situation until the prosthetic therapy by means of a complete maxillary denture and an implant-supported mandibular overdenture rigidly retained with a milled bar.

[How can the mentally ill achieve sustained employment? Supported employment versus pre-vocational training]

People with severe mental disorders are often without work, although work may have a positive effect on their health. The paper presents some results in this field from the German S3 guidelines on psychosocial therapies. In terms of evidence-based medicine supported employment (SE - first place then train) has proven to be most effective. Nevertheless, SE is still rare in Germany. Pre-vocational training, however, follows the concept first train then place and is offered in rehabilitation of the mentally ill (RPK) centres in Germany. There is some evidence that the programs are beneficial for users. The UN Convention for the Rights of Persons with Disabilities outlines an obligation for work on an equal basis with others and for vocational training. So far, the German mental health system only partly meets these requirements.

[Gerodontology consultation in geriatric facilities: general health status (I)]

Dental undertreatment is often seen in the older population. This is particularly true for the elderly living in nursing homes and geriatric hospitals. The progression of chronic diseases results in loss of their independence. They rely on daily support and care due to physical or mental impairment. The visit of a dentist in private praxis becomes difficult or impossible and is a logistic problem. These elderly patients are often not aware of oral and dental problems or these are not addressed. The geriatric hospital Bern, Ziegler, has integrated dental care in the concept of physical rehabilitation of geriatric patients. A total of 139 patients received dental treatment in the years 2005/2006. Their mean age was 83 years, but the segment with > 85 years of age amounted to 46%. The general health examinations reveald multiple and complex disorders. The ASA classification (American Society of Anesthesiologists, Physical Status Classification System) was applied and resulted in 15% = P2 (mild systemic disease, no functional limitation), 47% = P3 (severe systemic disease, definite functional limitations) and 38% = P4 (severe systemic disease, constant threat to life). Eighty-seven of the patients exhibited 3 or more chronic diseases with a prevalence of cardiovascular diseases, musculoskelettal disorders and dementia. Overall the differences between men and women were small, but broncho-pulmonary dieseases were significantly more frequent in women, while men were more often diagnosed with dementia and depression. Verbal communication was limited or not possible with 60% of the patients due to cognitive impairment or aphasia after a stroke. Although the objective treatment need is high, providing dentistry for frail and geriatric patients is characterized by risks due to poor general health conditions, difficulties in communication, limitations in feasibility and lack of adequate aftercare. In order to prevent the problem of undertreatment, elderly independently living people should undergo dental treatment regularly and in time. Training of nurses and doctors of geriatric hospitals in oral hygiene should improve the awareness. A multidisciplinary assessment of geriatric patients should include the oral and dental aspect if they enter the hospital.

Prosthetically driven, computer-guided implant planning for the edentulous maxilla: a model study

OBJECTIVES: To analyze computer-assisted diagnostics and virtual implant planning and to evaluate the indication for template-guided flapless surgery and immediate loading in the rehabilitation of the edentulous maxilla. MATERIALS AND METHODS: Forty patients with an edentulous maxilla were selected for this study. The three-dimensional analysis and virtual implant planning was performed with the NobelGuide software program (Nobel Biocare, Göteborg, Sweden). Prior to the computer tomography aesthetics and functional aspects were checked clinically. Either a well-fitting denture or an optimized prosthetic setup was used and then converted to a radiographic template. This allowed for a computer-guided analysis of the jaw together with the prosthesis. Accordingly, the best implant position was determined in relation to the bone structure and prospective tooth position. For all jaws, the hypothetical indication for (1) four implants with a bar overdenture and (2) six implants with a simple fixed prosthesis were planned. The planning of the optimized implant position was then analyzed as follows: the number of implants was calculated that could be placed in sufficient quantity of bone. Additional surgical procedures (guided bone regeneration, sinus floor elevation) that would be necessary due the reduced bone quality and quantity were identified. The indication of template-guided, flapless surgery or an immediate loaded protocol was evaluated. RESULTS: Model (a) - bar overdentures: for 28 patients (70%), all four implants could be placed in sufficient bone (total 112 implants). Thus, a full, flapless procedure could be suggested. For six patients (15%), sufficient bone was not available for any of their planned implants. The remaining six patients had exhibited a combination of sufficient or insufficient bone. Model (b) - simple fixed prosthesis: for 12 patients (30%), all six implants could be placed in sufficient bone (total 72 implants). Thus, a full, flapless procedure could be suggested. For seven patients (17%), sufficient bone was not available for any of their planned implants. The remaining 21 patients had exhibited a combination of sufficient or insufficient bone. DISCUSSION: In the maxilla, advanced atrophy is often observed, and implant placement becomes difficult or impossible. Thus, flapless surgery or an immediate loading protocol can be performed just in a selected number of patients. Nevertheless, the use of a computer program for prosthetically driven implant planning is highly efficient and safe. The three-dimensional view of the maxilla allows the determination of the best implant position, the optimization of the implant axis, and the definition of the best surgical and prosthetic solution for the patient. Thus, a protocol that combines a computer-guided technique with conventional surgical procedures becomes a promising option, which needs to be further evaluated and improved.

[The stamp technique for direct composite restoration]

The indications for direct resin composite restorations are nowadays extended due to the development of modern resin materials with improved material properties. However, there are still some difficulties regarding handling of resin composite material, especially in large restorations. The reconstruction of a functional and individual occlusion is difficult to achieve with direct application techniques. The aim of the present publication was to introduce a new "stamp"-technique for placing large composite restorations. The procedure of this "stamp"-technique is presented by three typical indications: large single-tooth restoration, occlusal rehabilitation of a compromised occlusal surface due to erosions and direct fibre-reinforced fixed partial denture. A step-by-step description of the technique and clinical figures illustrates the method. Large single-tooth restorations can be built-up with individual, two- piece silicone stamps. Large occlusal abrasive and/or erosive defects can be restored by copying the wax-up from the dental technician using the "stamp"-technique. Even fiber-reinforced resin-bonded fixed partial dentures can be formed with this intraoral technique with more precision and within a shorter treatment time. The presented "stamp"-technique facilitates the placement of large restoration with composite and can be recommended for the clinical use.

Are land sparing and land sharing real alternatives for European agricultural landscapes?

There is a lively debate on whether biodiversity conservation and agricultural production could be better reconciled by land sparing (strictly separating production fields and conservation areas) or by land sharing (combining both, agricultural production and biodiversity conservation on the same land). The debate originates from tropical countries, where agricultural land use continues to increase at the expense of natural ecosystems. But is it also relevant for Europe, where agriculture is withdrawing from marginal regions whilst farming of fertile lands continues to be intensified? Based on recent research on farmland biodiversity we conclude that the land sharing – land sparing dichotomy is too simplistic for Europe. Instead we differentiate between productive and marginal farmland. On productive farmland, semi-natural habitats are required to yield ecosystem services relevant for agriculture, to promote endangered farmland species which society wants to conserve even in intensively farmed regions, and to allow migration of non-farmland species through the agricultural matrix. On marginal farmland, high-nature value farming is a traditional way of land sharing, yielding high quality agricultural products and conserving specialized species. To conserve highly disturbance-sensitive species, there is a need for nature reserves. In conclusion, land sparing is not a viable olution for Europe in both productive and marginal farmland but because of different reasons in each type of farmland.

Cardiopulmonary performance testing using a robotics-assisted tilt table: Feasibility assessment in able-bodied subjects

BACKGROUND: Robotics-assisted tilt table technology was introduced for early rehabilitation of neurological patients. It provides cyclical stepping movement and physiological loading of the legs. The aim of the present study was to assess the feasibility of this type of device for peak cardiopulmonary performance testing using able-bodied subjects. METHODS: A robotics-assisted tilt table was augmented with force sensors in the thigh cuffs and a work rate estimation algorithm. A custom visual feedback system was employed to guide the subjects' work rate and to provide real time feedback of actual work rate. Feasibility assessment focused on: (i) implementation (technical feasibility), and (ii) responsiveness (was there a measurable, high-level cardiopulmonary reaction?). For responsiveness testing, each subject carried out an incremental exercise test to the limit of functional capacity with a work rate increment of 5 W/min in female subjects and 8 W/min in males. RESULTS: 11 able-bodied subjects were included (9 male, 2 female; age 29.6 ± 7.1 years: mean ± SD). Resting oxygen uptake (O_{2}) was 4.6 ± 0.7 mL/min/kg and O_{2}peak was 32.4 ± 5.1 mL/min/kg; this mean O_{2}peak was 81.1% of the predicted peak value for cycle ergometry. Peak heart rate (HRpeak) was 177.5 ± 9.7 beats/min; all subjects reached at least 85% of their predicted HRpeak value. Respiratory exchange ratio (RER) at O_{2}peak was 1.02 ± 0.07. Peak work rate) was 61.3 ± 15.1 W. All subjects reported a Borg CR10 value for exertion and leg fatigue of 7 or more. CONCLUSIONS: The robotics-assisted tilt table is deemed feasible for peak cardiopulmonary performance testing: the approach was found to be technically implementable and substantial cardiopulmonary responses were observed. Further testing in neurologically-impaired subjects is warranted.

Is mental practice an effective adjunct therapeutic strategy for upper limb motor restoration after stroke?

Stroke is one of the most common conditions requiring rehabilitation, and its motor impairments are a major cause of permanent disability. Hemiparesis is observed by 80% of the patients after acute stroke. Neuroimaging studies showed that real and imagined movements have similarities regarding brain activation, supplying evidence that those similarities are based on the same process. Within this context, the combination of MP with physical and occupational therapy appears to be a natural complement based on neurorehabilitation concepts. Our study seeks to investigate if MP for stroke rehabilitation of upper limbs is an effective adjunct therapy. PubMed (Medline), ISI knowledge (Institute for Scientific Information) and SciELO (Scientific Electronic Library) were terminated on 20 February 2015. Data were collected on variables as follows: sample size, type of supervision, configuration of mental practice, setting the physical practice (intensity, number of sets and repetitions, duration of contractions, rest interval between sets, weekly and total duration), measures of sensorimotor deficits used in the main studies and significant results. Random effects models were used that take into account the variance within and between studies. Seven articles were selected. As there was no statistically significant difference between the two groups (MP vs Control), showed a – 0.6 (95% CI: –1.27 to 0.04), for upper limb motor restoration after stroke. The present meta-analysis concluded that MP is not effective as adjunct therapeutic strategy for upper limb motor restoration after stroke.

Submaximal cardiopulmonary thresholds on a robotics-assisted tilt table, a cycle and a treadmill: a comparative analysis

BACKGROUND: The robotics-assisted tilt table (RATT), including actuators for tilting and cyclical leg movement, is used for rehabilitation of severely disabled neurological patients. Following further engineering development of the system, i.e. the addition of force sensors and visual bio-feedback, patients can actively participate in exercise testing and training on the device. Peak cardiopulmonary performance parameters were previously investigated, but it also important to compare submaximal parameters with standard devices. The aim of this study was to evaluate the feasibility of the RATT for estimation of submaximal exercise thresholds by comparison with a cycle ergometer and a treadmill. METHODS: 17 healthy subjects randomly performed six maximal individualized incremental exercise tests, with two tests on each of the three exercise modalities. The ventilatory anaerobic threshold (VAT) and respiratory compensation point (RCP) were determined from breath-by-breath data. RESULTS: VAT and RCP on the RATT were lower than the cycle ergometer and the treadmill: oxygen uptake (V'O2) at VAT was [mean (SD)] 1.2 (0.3), 1.5 (0.4) and 1.6 (0.5) L/min, respectively (p < 0.001); V'O2 at RCP was 1.7 (0.4), 2.3 (0.8) and 2.6 (0.9) L/min, respectively (p = 0.001). High correlations for VAT and RCP were found between the RATT vs the cycle ergometer and RATT vs the treadmill (R on the range 0.69-0.80). VAT and RCP demonstrated excellent test-retest reliability for all three devices (ICC from 0.81 to 0.98). Mean differences between the test and retest values on each device were close to zero. The ventilatory equivalent for O2 at VAT for the RATT and cycle ergometer were similar and both were higher than the treadmill. The ventilatory equivalent for CO2 at RCP was similar for all devices. Ventilatory equivalent parameters demonstrated fair-to-excellent reliability and repeatability. CONCLUSIONS: It is feasible to use the RATT for estimation of submaximal exercise thresholds: VAT and RCP on the RATT were lower than the cycle ergometer and the treadmill, but there were high correlations between the RATT vs the cycle ergometer and vs the treadmill. Repeatability and test-retest reliability of all submaximal threshold parameters from the RATT were comparable to those of standard devices.

Rehabilitación de un paciente desdentado total con sobredentadura

Con el advenimiento de los implantes y con ellos la opción de las sobredentaduras, la pasividad comienza a jugar un papel fundamental para darle mejor pronóstico a la rehabilitación y prolongar la vida útil de los implantes. Dentro de este análisis es que se presenta el caso clínico de un paciente portador de prótesis completa superior e inferior, tratado dentro del marco de la Carrera de Especialista en Prostodoncia de la Universidad Nacional de Cuyo. El tratamiento propuesto al paciente fue: dos implantes en el maxilar inferior con una sobredentadura retenida por pilares esféricos y cuatro implantes superiores con una sobredentadura retenida por una barra, la cual feruliza los implantes. La barra superior fue colada seccionada en cuatro partes, unidas en boca y luego soldadas mediante tecnología láser. De esta forma se busca obtener pasividad para evitar aflojamiento de tornillos de fijación, fractura de tornillos o implantes, reabsorción de los tejidos óseo perimplantarios o pérdida de la oseointegración de los implantes.

Maceral distribution, stratigraphic position and vitrinite reflectance at DSDP Hole 81-555

Twenty-four sediment samples from late Paleocene to early Eocene were studied for maceral content, vitrinite reflectance, and spectral fluorescence in order to determine some parameters of the origin and diagenetic history of their organic fraction. The sediments had been obtained at Site 555 of DSDP Leg 81 in the northeastern North Atlantic. The bulk of the microscopically visible fraction is made up of humic materials; inertinites follow as a distant second; and liptinites are exceedingly rare. No unequivocal evidence of marine organic matter was found. Humic materials are highly decomposed, showing signs of aerobic (frequency of sclerotinites) as well as anaerobic (abundance of and intimate association with framboidal pyrite) microbial degradation. Vitrinite reflectance values vary between 0.26 and 0.35 Ro and show a slight increase with depth. These values, indicative of a low-rank lignite stage of coalification, contrast somewhat with the sporinite fluorescence spectra, which show the configuration typical for the peat stage. In either case, the evidence for such a low stage of coalification is surprising in view of the depth and age of the sediments.

Concienciación para la conservación del patrimonio urbano : los instrumentos de gestión para la recuperación del barrio madrileño de Embajadores

La tesis trata la evolución de la conciencia de la conservación de los centros históricos y de los instrumentos de gestión utilizados en las políticas de rehabilitación del casco antiguo de Madrid, desde las primeras experiencias de los años ‘80 hasta el perfeccionamiento del complejo mecanismo contemporáneo. El proceso de rehabilitación ha demostrado ser extremadamente coherente en cuanto a los objetivos y en cuanto al tema de los instrumentos ha seguido la tendencia de diversificar y flexibilizar. En Madrid se ha utilizado el concepto de rehabilitación en sentido integral, abarca una amplia gama de acciones que implican por una parte, intervenciones directas sobre los edificios y por otra, la valorización del espacio público, de los edificios representativos, la introducción de dotaciones y también un componente social. El tema se analizará desde la perspectiva del barrio de Embajadores, un área muy especial del casco antiguo de la ciudad. Desde 1998 hasta la actualidad allí funciona el Área de Rehabilitación Integral con el nombre de Lavapiés. El barrio de Embajadores representa un caso de extrema complejidad dada su tradición, que mantiene hasta el momento, de barrio popular que ha tenido como consecuencia negativa un grave estado de deterioro de los edificios y de sus estructuras urbanas. Además, presenta una composición socio-cultural muy heterogénea ya que siempre ha alojado oleadas de inmigrantes que llegaban a la capital tanto de las provincias como del extranjero. Los ‘80 marcan en Madrid el inicio de la preocupación por la rehabilitación urbana y de los primeros intentos de definir unos mecanismos. Durante este período el barrio de Embajadores es escenario de los primeros proyectos piloto de rehabilitación. Se sientan las bases del sistema de subvenciones, que empujará hacia un modelo de rehabilitación generalizada. A principios de los años ‘90, la insatisfacción dejada por de los resultados obtenidos, la Administración decide reorganizar la estrategia y se procede a la rehabilitación integral por áreas, concentrando los esfuerzos geográfica y temporalmente. La idea ya se había utilizado diez años antes, pero sin encontrar nunca la voluntad política de aplicarla. En comparación con el casco antiguo, el barrio de Embajadores se dejó para el final del proceso para verificar los métodos en zonas más restringidas en cuanto a superficie y con menos problemas. Desde 1998 hasta hoy, período en que funciona el Área de Rehabilitación Integral de Lavapiés, los distintos tipos de actuaciones, de producción arquitectónica, urbanística y sociocultural, han mostrado su eficacia, de forma que los cambios que aportaron al barrio son evidentes para todos. Mientras que las Áreas de Rehabilitación del centro una vez alcanzados los objetivos, se preparan para su clausura, a nivel administrativo se están definiendo nuevas direcciones y nuevos objetivos para el casco antiguo: subastas para incentivar intervenciones de mejoramiento energético y del nivel de sostenibilidad de los edificios madrileños. La primera parte de la tesis establece las premisas presentando algunos puntos relevantes relativos al desarrollo histórico de los documentos y normativas más importantes que tendrán eco en el proceso de concienciación de la cultura de la conservación del patrimonio urbano de los centros históricos. Después, se habla de la experiencia de rehabilitación urbana en Europa, en España en general y en Madrid en particular, con referencia a los modelos de enfoque, al marco legislativo y a las experiencias relacionadas con el casco antiguo, y en definitiva a la creación de la conciencia de la rehabilitación y conservación de los centros de las ciudades. La segunda parte se centra en el caso de estudio, el barrio de Embajadores. En primer lugar, se presenta en detalle el barrio: ubicación, datos característicos, edificios representativos y flujos que generan, trama urbana, datos sobre la formación histórica, tipologías y características de construcción de los edificios y, para finalizar, algún dato demográfico para introducir la compleja problemática social. Más adelante se exponen las primeras experiencias de rehabilitación: dos proyectos piloto de intervención sobre las viviendas realizados en los años ‘80, uno privado y el otro público. La parte central del trabajo trata sobre la fase intensiva de rehabilitación, proceso puesto en marcha en el año ’98 y que corresponde al período en el que Embajadores es Área de Rehabilitación Integral. Se presentan y analizan los objetivos de la rehabilitación y luego los instrumentos de orden administrativo, normativo y legal que regulan las actuaciones en el barrio. Sucesivamente se afronta la rehabilitación de la parte residencial, en régimen privado y público, que fue el modelo principal que la Administración llevó a cabo. Se presenta todo el proceso, desde la decisión sobre el tipo de rehabilitación, las subvenciones y las soluciones técnicas adoptadas así como la rehabilitación de casos especiales de edificios, que por sus características, el alto nivel de degradación o porque ocupados por inquilinos con dificultades económicas, se realizó con intervención pública. Las enormes dificultades derivadas de la complicada gestión y de las incongruencias de las normativas también se analizan en este trabajo. El autor presenta un dosier de una veintena de trabajos llevados a cobo en el Barrio de Embajadores a lo largo de más de 15 años de experiencia profesional propia. Se intenta, en primer lugar, evaluar la actuación pública en comparación con la privada en cuanto a los modelos propuestos, a las problemáticas que generan y a los resultados obtenidos. Una segunda línea de argumentación se refiere a la relación que se establece entre los instrumentos que se promueven y los que obligan a la conservación y a la rehabilitación de los edificios. Quizás el elemento más interesante, por su conocida innovación, de la experiencia de la obligación de conservación a cargo de los propietarios y la introducción de una revisión periódica del estado de los edificios (ITE), que conduce a su mantenimiento permanente a lo largo del tiempo. El ultimo instrumento aparecido y de por si el más novedoso se refiere a la política de rehabilitación energética iniciada en los últimos años por el Ayuntamiento de Madrid. ABSTRACT Starting from the early experiences of the ‘80s and tackling the complex and improved contemporary techniques of development, the present thesis focuses on raising awareness of the conservation of urban heritage and deals with the evolution of rehabilitation policies adopted in the historical center of Madrid. The rehabilitation process has proven to be extremely coherent in terms of its objectives and, consequently, the subject of the instruments has forged ahead a trend of diversification and flexibility. Madrid has used the concept of rehabilitation in a comprehensive manner, encompassing a wide range of actions, which involved on the one hand, direct interventions on buildings and on the other, the appreciation of the public space with its representative edifices and endowments. Confident that the social components have not been neglected during the rehabilitation proceedings, the topic will be analysed in relation to the neighbourhood of Embajadores, an authentic area of the old town. From 1998 onwards, this quarter serves as a Comprehensive Rehabilitation Area under the name of Lavapies. Considering the tradition and popularity of the district, Embajadores represents a challenging case for rehabilitation projects, aiming to improve the severe state of deterioration of buildings and urban structures. Having a heterogeneous sociocultural dynamic, the neighbourhood has always hosted waves of immigrants who come to the capital both from other provinces and abroad. The 1980s in Madrid marked the beginning of concerns with urban regeneration and the first attempts to define feasible restoration techniques. During this period, the district of Embajadores has benefited from various pilot projects. The financial investments have significant effects on the overall environment, so the model of general rehabilitation has been encouraged throughout the years. In the early 90s, left by the dissatisfaction of the results obtained, the authorities proposed to reorganise the strategy and proceed to the full rehabilitation of areas, concentrating efforts geographically and temporally. The idea had already been used ten years before, but never encountered the political force to be implemented. Compared to the old town, the Embajadores neighbourhood has been left for the end of the process, which focused on verifying the methods in more restricted areas that caused fewer disruptions. For the Comprehensive Rehabilitation Area of Lavapies, the various types of administrative implementations from architectural to urban and socio-cultural productions have proved effective. The improvements experienced by the neighbourhood from 1998 are obvious to all. However, while the areas of rehabilitation of the city centre have achieved their objectives and prepare for closure, the administration is still generating new directions and new targets for the ancient surroundings: auctions to encourage the improvement of energy interventions and the sustainability level for the buildings of Madrid. Therefore, the first part of the thesis establishes the premises and introduces some relevant points concerning the entire city. It describes the historical development of urban projects, indicating the events that will echo in the rehabilitation process. This paper then turns to discuss the experience of urban regeneration in Spain, emphasising the case of Madrid with reference to models of approach, legislative frameworks and appreciation of the old structures. The second part reveals an in depth case study of the district of Embajadores. At first, the thesis provides insights into the neighbourhood: location, general data on representative buildings and propagated trends, urban, historical data on training, building typologies and characteristics. The section introduces some demographic data to complete the portrait of the elaborate social problems encountered in this district, also outlining the first experiences of rehabilitation: two pilot projects on housing intervention made in the 80s, one private and one public. The central part of the thesis deals with the intensive phase of rehabilitation developments launched in the year '98 when Embajadores joined the Comprehensive Rehabilitation Area. It analyses the goals of rehabilitation and the instruments of administrative, regulatory and governing legal proceedings of the neighbourhood. The following chapter addresses the privately and publicly founded plan of residential rehabilitation that constituted the main model conducted by the authorities. It describes the entire process: deciding the type of restoration, subsidies and technical solutions as well as the degree of rehabilitation for special buildings, which either have a high level of degradation or require public intervention when tenants face financial difficulties. The administrative difficulties caused by the enormous bureaucratic machinery and the inconsistencies in regulations are also discussed in this paper. Thus, a just evaluation of the public and private performances regarding the proposed models of rehabilitation, along with the problems they generate and the results obtained is desired throughout the thesis. A second line of argument concerns the relationship established between the instruments that are promoted and requiring conservation and the building restoration. Perhaps the most interesting and innovative element of the new rehabilitation policies is the owners' obligation to preserve their properties and the introduction of a periodic review for the state of the buildings (ITE). These thorough and meticulous regulations lead to an ongoing maintenance of constructions, preventing them from severe or sudden deteriorations.
