Published: November 2017

The typical treatment of ameloblastoma is by surgery. The result of the procedure nevertheless  does  not always lead to complete healing of the sickness but to a recurrence during the post-operative period. It has been reported by a number of authors that the recurrence of the condition is influenced by a number of factors such as the kind of surgical intervention, the histological variant of the ameloblastoma and the incomplete removal of the tumor. The purpose of this research is to study the incidence of recurrence of ameloblastoma after surgery, taking into consideration type of surgery and size of the tumor. A study of 76 cases of ameloblastoma with different histological structures was undertaken in the laboratory of pathological anatomy of Central Research Institute of Dental and Maxillofacial Surgery. Data such as the recurrence of the disease and tumors size was collected, registered and analysed. The size of the tumors was expressed in conventional units. The analysis showed that basal cell and plexiform variants of ameloblastoma are often relate to cases with aggressive clinical courses. The tendency to the recurrence of the disease was also observed in the follicular and acanthomatous variants. According to the results of this study, cases of peripheral variants of ameloblastoma have the best prognosis.
Elliptical ring distribution probability-based damage imaging method for complex aircraft structures
Authors: Liu Guoqiang , Xiao Yingchun , Zhang Hua , Ren Gexue
Published: November 2017

In engineering applications, the robustness and effectiveness of damage diagnostic imaging for guided wave-based structural health monitoring could be affected by the complexity of structures. In this study, an elliptical ring distribution probability-based diagnostic imaging algorithm is proposed to mitigate this effect using the estimated wave velocity and damage index. This algorithm improves the ability of damage localization by modifying the defect distribution probability of probability-based diagnostic imaging. The elliptical ring distribution probability of the presence of defect is used for each sensing path in the algorithm. The width of the elliptical ring distribution probability is determined by the range of estimated wave velocity. The amplitude of the elliptical ring distribution probability is determined by the damage index. The damage location is determined by the cross region of different elliptical rings for different sensing paths. The capability of the algorithm is validated by identifying damages at different locations on a complex composite fuselage panel. The results show that the proposed algorithm can identify a single damage accurately and it can identify multiple damages effectively as well.
Numerical investigation on impacts of leakage sizes and pressures of fluid conveying pipes on aerodynamic behaviors
Authors: Mu Zheng , Zhang Hong Guang
Published: November 2017

Small hole leakage of pipes caused by erosion and perforation is the major form leading to the leakage. The leakage rate is an important premise and foundation for consequence computation and risk evaluation. Those published papers fail to systematically study impacts of initial pressures and leakage sizes of a pipe on the leakage rate. More numerical simulation results are not verified by experimental test. This paper applies numerical simulation technology to establish the model of small hole leakage in pipes, designs and processes different leakage modules to simulate different leakage scenes, and then experimentally validates the model correctness. On this basis, this paper studies impacts of initial pressures and leakage sizes on leakage rates and obtains fluid dynamic characteristics around the leakage hole, including velocity distribution and pressure distribution. However, in actual engineering, the position of leakage hole could not be predicted and changed in general. Therefore, this paper further studies impacts of leakage hole positions on the pipe leakage rate. In this way, this research is refined and could provide a theoretical basis for emergency rescue and accident survey of pipe leakage accidents.
Experimental investigation of the effect of internal flow velocity on VIV characteristics of vertical top tension risers in a semi-uniform current
Authors: Li Peng , Zheng Hong Fei , Wang Fei , Zhang Li
Published: November 2017

An experiment of the effect of internal flow velocity on vortex induced vibration characteristics of vertical top tension risers was carried out in a large scale wind-wave-current flume. A transparent poly riser model with effective length of 1.5 m was tested with the upper 0.75 m in the air and the lower 0.75 m in a uniform flow field. By changing the internal flow velocity, the dynamic characteristics and dynamic responses of top tension risers, the effect of internal flow velocity on VIV amplitude of the risers under different top tensions, and the top tension variation of the risers under different internal flow velocities were investigated in a semi-uniform current. Results show that the natural frequency of risers decreases with the increase of internal flow velocity, and is subjected to significant mutual inhibition between internal flow and top tension; as internal flow velocity increases, the external flow velocity needed for the “lock in” state to occur decreases, which is negative to the safe service of risers; increase of internal flow velocity leads to gradual increase of riser displacement, though at a smaller rate of variation than that caused by top tension. Axial force measurement indicates that, under a modest initial top tension, internal flow velocity makes a great difference to the top tension of risers. This suggests that internal flow velocity can offset some of the riser responses induced by top tension except when the initial top tension is high, in which case internal flow velocity does not make much difference to top tension.
Controlling quarter car suspension system by proportional derivative and positive position feedback controllers with time delay
Authors: Abdelhafez H. M. , Omara Osama
Published: November 2017

The active car suspension system is presented here to suppress the vibration of the car by applying proportional derivative (PD) and positive position feedback (PPF) controllers with time delay. The control signal output of the controller is applied electrically to the magneto-rheological (MR) damper or Electrical-rheological (ER) damper which is attached parallel to the passive components to improve the suppression of the vibration. The electrical control signal is produced by electronic circuits or programmable logic controller and the two-position sensor feedback signal which are connected to the controller. The approximate solutions of PD and PPF suspension systems are obtained by applying multiple time scales perturbation method. The effects of parameters variation of both the system and the controllers are investigated to achieve the best performance. Simulation results show good performance of the designed controllers.
Computing eigenpair derivatives of asymmetric damped system by generalized inverse
Authors: Wang Pingxin , Yang Xibei , Mi Jusheng
Published: November 2017

Many existing approaches for asymmetric damped system are based on the assumption that the eigenvalues are simple or semisimple with separated derivatives. This paper presents a new algorithm for computing the derivatives of the semisimple eigenvalues and corresponding eigenvectors of asymmetric damped system. Compared with the existing methods, the algorithm can be applicable to problems whether the repeated eigenvalues have well separated derivatives. In the proposed method, the derivatives of eigenvectors are divided into a particular solution and a homogeneous solution, where the particular solution is constructed by using generalized inverse matrix. The effectiveness of the proposed algorithm is illustrated by one numerical example.

Published: November 2017

Coal augers is a new type of mining equipment used in thin coal seam, and directional drilling performance of its drilling tools becomes the key issue in the equipment service life and drilling efficiency. The drilling test bench of a three-bit coal auger is constructed to study vibration and deflection performance of its drilling tools in this paper. Based on some reasonable simplifications and hypotheses of drilling tools, simulation model of a three-bit coal auger is established to analyze its vibration and deflection performance with different drilling depths. Then a novel drill rod stabilizer is designed and the simulation model of a three-bit coal auger with this stabilizer is constructed compared with a normal coal auger to study vibration and deflection performance of drilling tools, which provides scientific basis for stabilizers’ arrangement form. Research shows that: the simulation results accords with test results, which verifies correctness and rationality of simulation; vibration and deflection of drilling tools become greater with drilling depth increasing; drill rod stabilizers can effectively reduce drilling tools’ vibration and deflection, and are arranged every 5 drill rods and air pipes which is optimal decision.

Authors: Nishizawa Uichi , Oohashi Taro , Toyama Shigeki
Published: November 2017

A spherical ultrasonic motor for space has been developed by this investigation. Development results of the spherical ultrasonic motor which can be driven under the high temperature environment of the atmospheric pressure were described by previous paper. The results about developed spherical ultrasonic motor which was investigated in the environment of low temperature and temperature cycle are described by this paper. First, it was confirmed that the spherical ultrasonic motor drives in low temperature environment of −120 °C. When durability tests for the spherical ultrasonic motor were carried out in temperature of −80 °C, approximately 60 minutes as accumulated drive time was achieved. Further, freezing phenomenon occurred on a sliding surface between stator and spherical rotor of the spherical ultrasonic motor, and drive of the spherical ultrasonic motor was disturbed. Next, when a drive experiments about the temperature cycle were carried out, influence of the temperature cycle to a torque was small. It was confirmed that the rotational speed decreases by the decline of piezoelectric of a piezoelectric element and the decline of the hardness of the adhesive to which a piezoelectric element and an elastic body are attached in high temperature environment. On the other hand, it was confirmed that the rotational speed decreases by the freezing which occurs on the sliding surface and the influence of the characteristic of the piezoelectric element in low temperature environment.
Signal denoising based on empirical mode decomposition
Authors: Klionskiy Dmitry , Kupriyanov Mikhail , Kaplun Dmitry
Published: November 2017

The present paper discusses the empirical mode decomposition technique relative to signal denoising, which is often included in signal preprocessing. We provide some basics of the empirical mode decomposition and introduce intrinsic mode functions with the corresponding illustrations. The problem of denoising is described in the paper and we illustrate denoising using soft and hard thresholding with the empirical mode decomposition. Furthermore, we introduce a new approach to signal denoising in the case of heteroscedastic noise using a classification statistics. Our denoising procedure is shown for a harmonic signal and a smooth curve corrupted with white Gaussian heteroscedastic noise. We conclude that empirical mode decomposition is an efficient tool for signal denoising in the case of homoscedastic and heteroscedastic noise. Finally, we also provide some information about denoising applications in vibrational signal analysis.

The paper discusses problems of sustainable development of transport systems with special attention paid to noise pollution and emission of harmful compounds of exhaust gases. It presents traffic flow model for a transport network, which can be applied for estimation of external costs of transport resulting from congestion and congestion-related effects like noise and harmful emission. Model includes structure of vehicle stock, segmentation of transport, characteristics of roads and elements of surroundings. It allows for computational experiments with traffic distribution into transport network and traffic management and, in consequence, estimation of environmental effects of traffic flow. Formal model was supported by numerical example for transport network of Mazowieckie voivodeship in Poland. The example is based on noise pollution and its external costs. The model was developed on the base of EMITRANSYS model for Mazowieckie in 2016.

Published: November 2017

The characteristics of sludge retained in a down-flow hanging sponge reactor were investigated to provide a better understanding of the sewage treatment process in the reactor. The organic removal and sulfur oxidation conditions were found to differ between the first layer and the following three layers. It was found that 63% and 59% of the organic matter was removed in the first layer, even though the hydraulic retention time was only 0.2 h. It is thought that the organic removal resulted from aerobic and anaerobic biodegradation on the sponge medium. The sulfate concentration increased 1.5–1.9-fold in the first layer, with almost no subsequent change in the second to fourth layers. It was shown that oxidation of sulfide in the influent was completed in the first layer. The result of the oxygen uptake rate test with an ammonium nitrogen substrate suggested that the ammonium oxidation rate was affected by the condition of dissolved oxygen (DO) or oxidation–reduction potential (ORP).

Authors: Han Honggui , Liu Zheng , Ge Luming , Qiao Junfei
Published: November 2017

One of the most important steps and the main bottleneck of the activated sludge wastewater treatment process (WWTP) is the secondary clarification, where sludge bulking is still a widespread problem. In this paper, an intelligent method, based on a knowledge-leverage-based fuzzy neural network (KL-FNN), is developed to predict sludge bulking online. This proposed KL-FNN can make full use of the data and the existing knowledge from the operation of WWTP. Meanwhile, a transfer learning mechanism is applied to adjust the parameters of the proposed method to improve the predicting accuracy. Finally, this proposed method is applied to a real wastewater treatment plant for predicting the sludge bulking risk, and then for predicting the sludge bulking. The experimental results indicate that the proposed prediction method can be used as a tool to achieve better performance and adaptability than the existing methods in terms of predicting accuracy for sludge bulking.

Published: November 2017

Let R be a commutative Noetherian ring with non-zero identity, a and b
proper ideals of R,M a finitely generated R-module with finite
projective dimension, and X a finitely generated R-module. We study the
cohomological dimensions of M and X with respect to a + b and a ? b. We
show that the inequality cda+b(M,X) ? cda(M,X) + cdb(X) holds true and
we find an equivalent condition for it to be equality.

A ring R is uniquely ?-clean if the power of every element can be uniquely
written as the sum of an idempotent and a unit. We prove that a ring R is
uniquely ?-clean if and only if for any a ? R, there exists an integer m
and a central idempotent e ? R such that am ? e ? J(R), if and only
if R is Abelian; idempotents lift modulo J(R); and R/P is torsion for
all prime ideals P ? J(R). Finally, we completely determine when a
uniquely ?-clean ring has nil Jacobson radical.

Image inpainting, a technique of completing missing or corrupted image
regions in undetected form, is an open problem in digital image processing.
Inpainting of large regions using Deep Convolutional Generative Adversarial
Nets (DCGAN) is a new and powerful approach. In described approaches the
size of generated image and size of input image should be the same. In this
paper we propose a new method where the size of input image with corrupted
region can be up to 4 times larger than generated image.

Published: November 2017

Prevalence of blood parasites in dogs in the Belgrade area has been
investigated continuously during the last 20 years, especially in clinically
suspicious dogs. In the period from 2014 to 2015, 249 blood samples of pets
(182) and shelter dogs (67) were examined. Using Giemsa-stained blood smears,
the presence of Babesia spp. was examined in erythrocytes and the presence of
morulae of Ehrlichia spp. and Anaplasma spp. in circu?lating monocytes and
granulocytes. To confirm positive findings of ehrlichiosis and ana?plasmosis
in blood smears, CaniV-4 Test Kit or IDEXX SNAP 4DX test was used. Infection
with two pathogens was found in 78/249 (31.32%) cases; in all cases, the
infection with one of the protozoa or bacteria was in combination with
heartworms. In blood-smears, babesiosis was found in 39.75% of pet dogs and
in 71.64% of shelter dogs, ehrlichiosis in 15.93% and 28.35%, and
anaplasmosis in 6.04% and 19.40%, respectivelly. From colected ticks,
relative abundance analysis revealed that the species Ixodes ricinus was
absolutely dominant and found in 50.53% (47/93), followed by Rhipicephalus
sanguineus ? 38.70% (36/93), Derma?centor marginatus ? 9.67% (9/93), D.

Published: November 2017

Objective:

To evaluate the effects of rapid maxillary expansion (RME) on the vocal quality, maxillary central incisors, midpalatal suture, and nasal cavity in patients with maxillary crossbite.

Materials and Methods:

Coronal CT scans of 30 subjects (14 boys, 16 girls; mean age, 12.01 ± 0.75) were taken before RME (T0), and at the end of the expansion phase (T1). Voice samples of all patients were recorded with a high-quality condenser microphone (RODE NT2-A) on a desktop computer at T0 and T1. Statistical analyses were performed using a paired-sample t-test. The degree of association between the changes in the voice parameters and nasal width was assessed with Pearson's correlation.

Results:

RME treatment produced a significant increase in the transverse dimensions of the midpalatal suture and nasal cavity between T0 and T1 (P < .05). The maximum F0 and jitter (%) results were shown to decrease statistically significantly from T0 to T1 (P < .001 and P = .042, respectively). Between T0 and T1, shimmer (%) and shimmer (dB) exhibited statistically significant increases (P = .037 and P = .019, respectively).

Conclusions:

After RME therapy, voice quality differences were found to be associated with increases in nasal width.

OBJECTIVE

To evaluate the 5-year effectiveness of a multidisciplinary Risk Assessment and Management Programme–Diabetes Mellitus (RAMP-DM) in primary care patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS

A 5-year prospective cohort study was conducted with 121,584 Chinese primary care patients with type 2 DM who were recruited between August 2009 and June 2011. Missing data were dealt with multiple imputations. After excluding patients with prior diabetes mellitus (DM)-related complications and one-to-one propensity score matching on all patient characteristics, 26,718 RAMP-DM participants and 26,718 matched usual care patients were followed up for a median time of 4.5 years. The effect of RAMP-DM on nine DM-related complications and all-cause mortality were evaluated using Cox regressions. The first incidence for each event was used for all models. Health service use was analyzed using negative binomial regressions. Subgroup analyses on different patient characteristics were performed.

RESULTS

The cumulative incidence of all events (DM-related complications and all-cause mortality) was 23.2% in the RAMP-DM group and 43.6% in the usual care group. RAMP-DM led to significantly greater reductions in cardiovascular disease (CVD) risk by 56.6% (95% CI 54.5, 58.6), microvascular complications by 11.9% (95% CI 7.0, 16.6), mortality by 66.1% (95% CI 64.3, 67.9), specialist attendance by 35.0% (95% CI 33.6, 36.4), emergency attendance by 41.2% (95% CI 39.8, 42.5), and hospitalizations by 58.5% (95% CI 57.2, 59.7). Patients with low baseline CVD risks benefitted the most from RAMP-DM, which decreased CVD and mortality risk by 60.4% (95% CI 51.8, 67.5) and 83.6% (95% CI 79.3, 87.0), respectively.

CONCLUSIONS

This naturalistic study highlighted the importance of early optimal DM control and risk factor management by risk stratification and multidisciplinary, protocol-driven, chronic disease model care to delay disease progression and prevent complications.

Radon is a natural radioactive gas that occurs due to the radioactive decay of radium (226Ra) present in rocks which, in turn, cames from the radioactive decay of uranium (238U), a primordial natural element. Along with factors such as porosity, permeability and humidity of the rocks and soils, pressure and temperature, geology setting plays one of the most important roles in the release of radon into the environment. Depending on the mineralogical compositions and characteristics of the bedrock from a certain area, a higher or lower concentration of radioactive minerals can be found in the rocks, which will directly influence the level of radon in the atmosphere, implicitly the concentration of radon measured in houses. In this study, a six months concentration of radon (222Rn) was assessed in 256houses from Cluj-Napoca area using CR-39 nuclear track detectors. Correlations between the indoor radon levels and the geological setting was further analyzed. The aim is to better understand the influence of geology on the concentration of radon levels in homes, in order to further identify other risk areas in terms of exposure to radon. Further investigation is needed on other factors influencing the accumulation of radon in high concentrations indoor, such as ventilation, occupation patterns or constructive and architectural features for typical houses. Therefore, the results of this work are considered to be important for indoor radon management in Romania.

The ambitious overall objective is focus on to the concept of "smart city" in terms of intelligent integrated solutions, which it aims to achieve in international premiere, in order to improve public health by increasing indoor environmental quality and optimizing the energy efficiency of housing in five urban areas of Romania.
In this study, the current status of the development of the prototype system for continuous monitoring and remote data transmission on radon levels and other household air pollutants (CO2, CO, VOCs and temperature, pressure and humidity sensors) is presented, as an important objective in the frame of the SMART_RAD_EN project. The prototype for intelligent monitoring system was assembled and now is involved in the testing process. Metrology and quality assurance of the prototype system will be carried out within accredited European laboratories and by consulting with the international scientific experts. Remote data transmitted will allow: (1) real time interactive visualization, of the impact of user behavior on indoor air quality; (2) information in case of exceeding threshold levels; (3) to produce estimates of future pollution as a result of the correlation with the meteorological parameters (temperature, pressure and humidity) and user activity. The system, metrological validated, will be implemented in 100 houses with high exposure to radon and other ambient pollutants from the main Romanian urban agllomerations – Cluj-Napoca, Bucuresti, Timisoara, Iasi and Sibiu.

ObjetivoAvaliar o conhecimento de enfermeiros da Atenção Primária à Saúde sobre as medidas de Suporte Básico de Vida utilizadas no tratamento da parada cardiorrespiratória em adultos e relacioná-lo com tempo de formação, experiência profissional e participação em cursos de atualização. MétodosCento e vinte e nove enfermeiros preencheram formulário contendo as variáveis do estudo e realizaram um teste com 10 questões de múltipla escolha. Resultados A pontuação média global foi preocupantemente baixa (4,5±1,9 pontos). Enfermeiros mais jovens, com menos tempo de formação e atuação em Atenção Primária à Saúde e com experiência em emergência ou cardiologia tiveram desempenho significativamente melhor. Enfermeiros que realizaram cursos práticos avançados de suporte de vida nos últimos dois anos também tiveram melhor desempenho, mas isto correspondeu a menos de 10% da amostra. ConclusãoA falta de experiência em emergências e a carência de treinamento regular contribuíram para o fraco desempenho dos enfermeiros que atuam na Assistência Primária à Saúde. Isso foi evidenciado na avaliação utilizada para medir o conhecimento sobre tratamento da parada cardiorrespiratória em adultos, indicando a necessidade de um programa de educação continuada.

función de la contabilidad. Una perspectiva sociofenomenológica
Authors: Cuenú Cabezas Jairo Emiro
Published: November 2017

El presente documento es un artículo de reflexión, que tiene como objetivo determinar la función de la contabilidad a partir de la sociología-fenomenológica del austriaco Alfred Schütz; el cual teoriza sobre el mundo de la vida cotidiana, explicando que existen tres clases de productos: los instrumentos, las marcas y las obras de arte. Desde Schütz, la contabilidad es un instrumento y una marca. Instrumento porque es útil para... y marca porque pretende recordar. Esto lo logró haciendo uso de la escritura y la arcilla, elementos que le permitieron manipular la memoria, ya que ésta no tiene la capacidad de recordar todas las acciones humanas. Con la sociología-fenomenológica, se determina que la contabilidad surgió por la poca capacidad de la memoria para recordar todas las acciones humanas realizadas por el hombre en el mundo de la vida cotidiana y en referencia a su zona económica de operación, zona que hace más de 6000 años, en Mesopotamia, había logrado un gran desarrollo con la acumulación, la concepción de la propiedad, la división del trabajo y los aspectos jurídicos; desarrollos que llevaron al hombre a dar orden a sus acciones y a lograr tener más y mejor información para el control; aspecto que logro con la contabilidad. En este orden de ideas en el artículo se determina que la contabilidad no surgió para suplir los fallos de la memoria, sino por la poca capacidad de la memoria para traer al presente todas las acciones humanas, especialmente las de carácter económico.

Authors: Moreno Fernández Rafael
Published: November 2017

Situados en la constitución del Banco de San Carlos, en el presente trabajo se analizan los informes que se elaboraron en 1783 para dotar al establecimiento, acordes con el diseño organizativo previsto en su norma fundacional, de la infraestructura necesaria para cubrir los aspectos contables que abarcan, desde los libros de cuentas, hasta el sistema a seguir por partida doble o simple, o el perfil, sueldo y personas que llevarían la contabilidad. Finalmente, sería el órgano colegiado de la Junta de Dirección el que decidiría tales aspectos, pero supeditando a la Junta General de Accionistas, al término de ese primer ejercicio, la resolución o confirmación de algunas cuestiones.

Authors: Rodríguez González Ricardo
Published: November 2017

El presente trabajo tiene por objeto contextualizar y, principalmente, describir y analizar el contenido de la contabilidad de Agustín Eyries, subcontratista de un tramo de la línea del ferrocarril Madrid-Irún entre El Escorial y Medina del Campo, poniendo de manifiesto la estructura contable utilizada para recoger las cuentas de explotación independientes de diversas obras de infraestructura ejecutadas durante el período comprendido entre 1857 y 1865, recogiendo las liquidaciones practicadas con la Compañía Norte, así como la derivación de los negocios hacia otras ramas de actividad una vez concluidas los obras del ferrocarril. De igual modo se recogen las cuentas de sus actividades e inversiones agropecuarias en Medina del Campo a la conclusión de las obras del ferrocarril independientes de las afectas a la construcción de la red. Una última serie de libros de cuentas recogerá las actividades comerciales posteriores de compraventa de productos y maquinaria agraria en Valladolid.
Análisis Histórico de las Prácticas de Contabilidad Financiera del Ferrocarril de la Sabana, Colombia (1881-1917)
Authors: Rico Bonilla Carlos Orlando
Published: November 2017

En el documento se propone un análisis histórico para describir y explicar, a partir de las correspondientes fuentes primarias y secundarias, algunas de las prácticas de contabilidad financiera aplicadas en la empresa colombiana del Ferrocarril de Sabana durante el periodo 1881 – 1917.

Se argumenta que la información financiera y los contadores de esta organización jugaron un papel valioso en la toma de decisiones económicas, especialmente, en temas de operación y liquidez. De igual forma que fue en compañías de esta industria, donde adquirió mayor relevancia la definición del tratamiento contable y la presentación de diferentes transacciones y eventos como la valoración y depreciación de activos fijos, el reconocimiento de las importaciones, la revelación de la cuenta de resultados, entre otros.
sistema contabile e la struttura di gobernó del “Campansi” nella seconda metà dell'ottocento
Authors: Catturi Giuseppe , Sorrentino Daniela
Published: November 2017

In ogni comunità civica esistono sempre entità sociali, economiche e politico-amministrative che, con la propria attività e struttura organizzativa, caratterizzano e rappresentano i momenti storico-culturali di quella comunità.

La comunità che vogliamo indagare è quella di Siena. Siena, infatti, è una città universalmente nota per il suo passato medievale e rinascimentale, ben riconoscibile anche oggi, sia per la sua struttura urbanistica che per i dipinti e il ricco patrimonio culturale di cui va molto fiera.

L'istituzione che identifichiamo come una di quelle che hanno caratterizzato, almeno nell'ultimo secolo e mezzo, e caratterizzano tuttora la storia e la cultura della città di Siena è il Ricovero di Mendicità, poi chiamato Casa di riposo in Campansi per anziani, universalmente conosciuto come "i Campansi".

Il Campansi non è l'unica istituzione la cui evoluzione strutturale e operativa ha contribuito, e contribuisce tuttora, alla storia di Siena dal punto di vista sociale, politico e istituzionale, ma è certamente una delle più caratteristiche e caratterizza la comunità perché svolge un'attività caritativa che ha reso grande Siena fino all'inizio del secondo millennio, quando si diffuse la pratica dei viaggi propiziatori o riparatori verso i grandi luoghi religiosi, Roma, Gerusalemme e Santiago de Compostela.

In questo articolo adotteremo la prospettiva di studio dell'economia aziendale, con particolare riferimento alla struttura del sistema contabile e alla documentazione che questa entità ha via via prodotto per memorizzare, sintetizzare e comunicare gli eventi amministrativi generati per l'esercizio della sua funzione istituzionale, analizzando anche la sua struttura di governance adottata per le decisioni operative, per la supervisione della sua attuazione e per la verifica degli effetti; esiste, infatti, una stretta interdipendenza tra il modello di governance di qualsiasi organizzazione e il suo sistema contabile.

Questo studio si riferisce, in particolare, all'arco temporale che riteniamo significativamente interessante, dalla promulgazione della legge del 3 agosto 1862, "Sull'amministrazione delle opere di culto", nota come "Legge Rattazzi", così chiamata dal Presidente del Consiglio al momento della presentazione parlamentare, e l'approvazione della "Legge Crispi", così chiamata dal capo del governo dell'epoca, sulle "Istituzioni pubbliche di beneficenza" avvenuta nel 1890.
