Procesos de Visualización en una Tarea de Generación y Representación de Cuerpos de Revolución
Authors: Blanco Teresa F. , Diego-Mantecón Jose Manuel , Sequeiros Pablo González
Published: July 2019

Resumen En este trabajo se analizaron los procesos de visualización implicados en una tarea que requiere generar y representar cuerpos de revolución. La tarea se administró a cuatrocientos estudiantes del grado de maestro de Educación Primaria. Se adoptó como marco teórico el enfoque Ontosemiótico de la Instrucción y el Conocimiento Matemáticos, utilizándose como herramienta analítica la noción de configuración en su vertiente epistémica y cognitiva. Para el análisis de datos se empleó una metodología de investigación mixta: con una componente cualitativa que evaluó las categorías de objetos primarios, y otra cuantitativa que categorizó el grado de corrección de las respuestas. El análisis de los procesos de visualización se realizó por medio de las nueve configuraciones cognitivas identificadas en las soluciones de los estudiantes. Los errores de resolución se concentraron más en el procesamiento visual de la información que en el proceso de interpretación de la información figurativa. La mayoría de ellos se debieron a dificultades para movilizar las habilidades de reconocimiento de relaciones y posiciones espaciales, observándose una correspondencia entre la efectividad de las configuraciones cognitivas y la representación externa de los cuerpos generados.

Resumo O estudo teve por objetivo avaliar a comercialização de alimentos em cantinas comerciais localizadas no âmbito escolar de diferentes redes de ensino, tipos de administração e presença ou não de profissional técnico (nutricionista). O estudo do tipo observacional foi realizado em 111 cantinas, sendo 35 estabelecimentos de ensino privado e 76 de ensino público de Curitiba, Paraná, Brasil. Para realizar estas avaliações, foi elaborada uma lista de verificação contendo um conjunto de condutas baseada nas legislações estaduais do Paraná. De acordo com as legislações vigentes, constatou-se que 97,37% das cantinas das instituições públicas e 94,29% das privadas comercializavam alimentos considerados proibidos por apresentarem baixo valor nutricional. Os principais alimentos proibidos comercializados nas cantinas foram os salgadinhos industrializados, os chocolates, as balas e os sucos artificiais. Esses também foram os alimentos e bebidas mais vendidos, segundo os responsáveis. Além disso, 73,87% das cantinas não possuíam supervisão técnica, 89,19% não disponibilizavam dois tipos de frutas e apenas 1,80% tinha mural educativo, conforme exigido pelas legislações vigentes. Conclui-se que as cantinas, independentemente da rede ensino e do tipo de administração, estão em desacordo com as legislações vigentes, tanto na comercialização de alimentos proibidos como na ausência de dois tipos de frutas e na ausência de mural educativo. Os resultados mostraram que a supervisão frequente do responsável técnico se faz necessária para contribuir nas escolhas dos alimentos comercializados e, consequentemente, melhorar a qualidade nutricional dos produtos expostos para venda.

Published: July 2019

Abstract Introduction: Intradialytic hypotension (IDH) is a major complication of hemodialysis, with a prevalence of about 25% during hemodialysis sessions, causing increased morbidity and mortality. Objective: To study the effects of sertraline to prevent IDH in hemodialysis patients. Methods: This was a double-blind, crossover clinical trial comparing the use of sertraline versus placebo to reduce intradialytic hypotension. Results: Sixteen patients completed the two phases of the study during a 12-week period. The IDH prevalence was 32%. A comparison between intradialytic interventions, intradialytic symptoms, and IDH episodes revealed no statistical difference in the reduction of IDH episodes (p = 0.207) between the two intervention groups. However, the risk of IDH interventions was 60% higher in the placebo group compared to the sertraline group, and the risk of IDH symptoms was 40% higher in the placebo group compared to the sertraline group. Survival analysis using Kaplan-Meier estimator supported the results of this study. Sertraline presented a number needed to treat (NNT) of 16.3 patients to prevent an episode from IDH intervention and 14.2 patients to prevent an episode from intradialytic symptoms. Conclusion: This study suggests that the use of sertraline may be beneficial to reduce the number of symptoms and ID interventions, although there was no statistically significant difference in the blood pressure levels.
The assessment of resting tongue posture in different sagittal skeletal patterns
Authors: Fatima Farheen , Fida Mubassar
Published: July 2019

ABSTRACT Introduction: Resting tongue posture affects the surrounding structures and, theoretically, may result in altered arch form and jaw relationship. Objective: The objective of the present study was to investigate the association between resting tongue posture as observed in lateral cephalometric radiograph, sagittal jaw relationship and arch form. Methods: The study was conducted on pretreatment lateral cephalograms and dental casts of 90 subjects. Subjects were equally divided into three groups, based on sagittal jaw relationship (Class I, II and III). Tongue posture was determined in terms of tongue-to-palate distances at six different points (distances 1 to 6) using ViewPro-X software, according to the method described by Graber et al in 1997. The arch widths (intercanine and intermolar widths) were evaluated on pretreatment dental casts. Results: Tongue-to-palate distances were found to be comparable among different study groups. Significant differences were found in intercanine and intermolar widths at the cuspal and gingival levels among the study groups, except for intercanine width at cuspal level in maxilla and intermolar width at cuspal level in mandible. Moderate positive correlation was found between arch widths ratios at distances 3 and 4 in skeletal Class III group. Effect size was found to be moderate to large in different sagittal skeletal patterns and arch widths. Conclusion: The results of the current study showed no significant differences in the resting tongue posture among the groups, and moderate to weak correlation between tongue posture and dental arch widths.

Published: July 2019

ABSTRACT Introduction: bonded fixed retainers are often used to stabilize the results obtained with the orthodontic treatment. It is important that they do not prejudice dental health, as they will be used for a long period. Objective: The purpose of the present study was to compare periodontal indexes between two types of bonded fixed retainers, conventional 3 x 3 plain retainer (0.8-mm orthodontic wire, bonded to the canines only) and a manufactured braided retainer (0.2 x 0.7-mm stainless steel wire, bonded to all anterior teeth) after use. Methods: a test group of 15 volunteers (aged from 18 to 25 years) used both the conventional retainer and braided retainer for six months. A randomized longitudinal study design, with a two week washout interval, was applied. The dental plaque index, gingival index and dental calculus index were evaluated. Furthermore, the calculus accumulated along the retainer wire was measured and all patients answered a questionnaire about the use, acceptance and comfort of both types of retainers. Results: the scores for plaque and gingival indexes were higher for the braided retainer (p< 0.05) on the lingual and proximal surfaces. The same occurred with the calculus index on the lingual surfaces (p< 0.05). The calculus index along wire was higher for the braided retainer (p< 0.05). All patients preferred the conventional retainer, and said that it was also more comfortable to use. Conclusion: it was concluded that the conventional retainer showed better periodontal indexes than the braided type.
Construction and validation of the Adult Stressors Inventory (ASI)
Authors: Benzoni Paulo Eduardo
Published: July 2019

Abstract Introduction A great deal of research has been conducted all over the world into stress and its impacts on the health of populations. Objective To develop and validate an instrument for identification of the principal stressors and their magnitude in people who are subject to stress. Method The instrument was constructed on the basis of analysis of 20 interviews conducted with 10 male and 10 female adults with stress according to the Perceived Stress Scale. A total of 46 statements were derived from this analysis, referring to stressful situations in different areas of life. Each statement is evaluated on a Likert response scale indicating the degree of impact and the respondent’s ability to deal with the stressor it describes. The instrument was validated with a non-probabilistic sample comprised 450 adults, aged from 18 to 65 years, 62.7% women and 37.3% men, who completed the instrument and also the Perceived Stress Scale, to enable criterion validation. Results Exploratory factor analysis identified 42 valid items and grouped them into eight factors that explained 64.5% of total variance. These factors were financial stressors; working environment stressors; cognitive and behavioral stressors; family environment stressors; health status stressors; stressors related to conditions for relaxation; workload-related stressors; and social relationship stressors. Cronbach’s alpha for the instrument was 0.94. A relationship was observed between the newly-developed inventory and the Perceived Stress Scale, providing grounds for accepting the validation hypothesis. Conclusions The results were psychometrically satisfactory and made possible provision of a new instrument for stress interventions, with advantages over other instruments.

Abstract Information about parasites associated with diurnal raptors from Chile is scarce. Between 2006 and 2017, a total of 15 specimens of the Variable hawk, Geranoaetus polyosoma (Quoy & Gaimard, 1824) were collected, 14 of them from different localities in the Biobío region and one specimen from the Valparaíso region. An external examination of the plumage was made to collect ectoparasites, and necropsies were performed, focusing primarily on the gastrointestinal tract. Chewing lice (Phthiraptera) were found on five (33.3%) of the birds corresponding to three species: 97 specimens of Degeeriella fulva (Giebel, 1874), six specimens of Colpocephalum turbinatum Denny, 1842 and nine belonging to an unidentified species of the genus Craspedorrhynchus Kéler, 1938. Endoparasites found in three (20%) of the birds included round worms (Nematoda) of the genus Procyrnea Chabaud, 1958, and spiny-headed worms (Acanthocephala) of the genus Centrorhynchus Lühe, 1911. The species Colpocephalum turbinatum and the genera: Craspedorrhynchus sp., Procyrnea sp. and Centrorhynchus sp. are new records for the Variable hawk.

Abstract The msp4 gene of A. marginale is unicodon, stable and mostly homogeneous, being considered as a useful marker for phylogeographic characterization of this bacterium. The objective of this work was to analyze the phylogeography of A. marginale based on the msp4 gene in beef cattle from the Brazilian Pantanal, compared to those found in other regions worldwide. The blood samples investigated were collected from 400 animals (200 cows and 200 calves) reared in five extensive breeding farms in this region. The results indicated that of the evaluated samples, 56.75% (227/400) were positive for A. marginale based on the msp1β gene by quantitatitve PCR (qPCR), while 8.37% (19/227) were positive for the msp4 gene in the conventional PCR. In the Network distance analysis, 14 sequences from the Brazilian Pantanal were grouped into a single group with those from Thailand, India, Spain, Colombia, Parana (Brazil), Mexico, Portugal, Argentina, China, Venezuela, Australia, Italy and Minas Gerais (Brazil). Among 68 sequences from Brazil and the world, 15 genotypes were present while genotype number one (#1) was the most distributed worldwide. Both Splitstree and network analyses showed that the A. marginale msp4 sequences detected in beef cattle from the Brazilian Pantanal showed low polymorphism, with the formation of one genogroup phylogenetically related to those found in ruminants from South and Central America, Europe, and Asia.
Early hydration of CSA cement modified with styrene–butadiene copolymer dispersion
Authors: Li Lin , Wang Ru
Published: July 2019

The effect of styrene–butadiene copolymer (SB) dispersion on the early hydration of calcium sulfoaluminate (CSA) cement was investigated. Pastes with five different ratios (0, 5, 10, 15 and 20%) of SB to CSA cement at a constant water to cement ratio of 0·4 were investigated by ultrasonic measurements, isothermal calorimetry, X-ray diffraction, thermogravimetry and scanning electron microscopy. It was found that SB retarded the initial hydration of the CSA cement paste within 3 h, during which time the formation of ettringite was strongly delayed. The hydration degree of the CSA cement paste was caught up by that of the SB-modified CSA cement paste at 3 h based on ultrasonic and calorimetry analysis. In addition, an increase in the addition of SB led to the generation of more ettringite and aluminium hydroxide. The most ettringite was formed and the size of ettringite crystals was increased in the pastes with 20% SB. Meanwhile, the addition of SB tended to reduce the amount of hemicarboaluminate in CSA cement pastes.
Towards efficient structural and serviceability design of high-strength concrete T-beams
Authors: Shaaban Ibrahim G. , Mustafa Tarek S.
Published: July 2019

Ten high-strength concrete (HSC) T-beams of total length 1700 mm, web breadth 100 mm, height 250 mm and different flange dimensions were experimentally tested until failure. The beam parameters studied were the flange dimensions and transverse and longitudinal reinforcement ratios. A numerical model was developed to predict the flexural behaviour of the tested beams. The results indicated that increasing breadth, depth and flange reinforcement ratio led to a reduction in the overall deflection and an enhancement of the ultimate load capacity. An empirical equation developed earlier by the authors for predicting the effective moment of inertia of HSC T-beams was successfully used to predict the load–deflection relationships of the studied beams. The load–deflection curves predicted by the numerical model, those predicted by this equation and those predicted by the Branson equation, which is currently used in design codes, were compared. Close agreement was found between the experimental results, numerical results and those obtained by the authors’ equation. This research thus highlights the need for updating the Branson equation used in design codes for deflection design of HSC T-beams by adopting the equation proposed by the authors.

A utilização de pastagens para a alimentação de ruminantes auxilia na diminuição dos custos de produção, aumentando a viabilidade da atividade. Com o objetivo de avaliar a potencialidade de produção de matéria seca (MS) e teores de proteína bruta (PB) de pastagens estivais perenes e anuais no sul do Brasil, conduziu-se um experimento fatorial em blocos casualizados, com 5 repetições de quatro forrageiras estivais, duas anuais (Milheto ou Pennisetum glaucum (L.) R. BR. e capim Sudão ou Sorghum bicolor cv. sudanense), e 2 perenes (Jiggs ou Cynodon dactilon sp. cv. Jiggs e Braquiária mulato II ou Brachiaria hibrida cv. Mulato II), totalizando 20 parcelas de 2,25 m2 (1,5 m x 1,5 m), com um metro de espaçamento entre si. Através de um quadrado de 0,25 m² (50 cm x 50 cm), lançado aleatoriamente em cada parcela, foram coletadas através de simulação de pastejo, amostras das cultivares, que foram analisadas quanto a produção de MS e teores de PB. Verificou-se maior potencialidade de produção em MS e teores médios de PB nas pastagens estivais perenes. O Jiggs apresentou uma produção acumulada em 4 cortes de 14.528 Kg de MS/ha e teores médios de PB de 11,35%. A Braquiária mulato II mostrou o melhor rendimento produtivo no segundo corte (4.036 kg de MS/ha) e teores médios de PB (10,28%) maiores que as pastagens estivais anuais, no entanto atingiu sua altura ideal de coleta somente em dois momentos (primeiro e segundo corte).
De esclavos a soldados de la patria: el Ejército Libertador como garante de la libertad y la ciudadanía
Authors: Conde Calderón Jorge Enrique
Published: July 2019

El reclutamiento de esclavos y libertos en las milicias, guerrillas y ejércitos conformados durante las guerras de Independencia fue un fenómeno creciente tanto en las filas de las fuerzas realistas como en la de los patriotas. Ambos prometieron a los reclutas con ese estatus social la libertad por su servicio militar, pero el Ejército libertador le sumó al hecho de ser personas libres la ciudadanía. Los libertos soldados, entonces, aprovecharon el contexto generado por la guerra para luchar y afianzar la libertad, la ciudadanía y otros derechos a través de memoriales y representaciones en los cuales emplearon un lenguaje revolucionario que en ocasiones trascendía las propuestas de los libertadores.

Este artículo pretende mostrar cómo hablar de ciencia útil en la segunda mitad del siglo XVIII, en el Nuevo Reino de Granada, expresó un vínculo orgánico entre determinadas ciencias y las prioridades del gobierno. La geografía, la botánica, la química, la medicina y, especialmente, la historia natural, proveían información sobre los recursos disponibles para la reorganización económica del imperio español. Aquellos científicos criollos que se dedicaron a las ciencias útiles terminaron siendo promotores de reformas que presentaron ante el tribunal de la opinión pública, en una forma de debate colectivo, como sucedió con el Semanario del Nuevo Reyno de Granada.
El discurso civilista en tiempos de la Gran Colombia
Authors: Chaparro Rodríguez Juan Carlos
Published: July 2019

Desde el momento en que se consumó la independencia de Colombia, y como efecto del legado militar que se heredó de la guerra, se generó una intensa discusión sobre los asuntos militares, y especialmente sobre el lugar y el papel que los uniformados debían ocupar y desempeñar en el marco del nuevo orden institucional. El desarrollo de ese debate no solo aparejó dicha discusión, sino que desembocó en la configuración de un ingenioso y persuasivo discurso civilista, en virtud del cual se intentó subordinar a los uniformados y cimentar el orden institucional de la república. Describir el contenido y alcance político de esos discursos y debates, a partir de lo que se publicó en algunos periódicos y documentos de la época; y dilucidar cómo influenciaron el curso de la vida política e institucional colombiana durante aquellos años, son los objetivos del presente artículo.

The Growing Role of Parliamentary Diplomacy in a Multipolar World
Authors: Varlen M. V.
Published: July 2019

The development of contemporary world politics puts new demands on the diplomacy of the 21st century that has rapidly transformed into a multilevel and complex system. The remarkable features and, at the same time, imperatives of diplomatic relations include globalization and multipolarity, turbulence and the multifaceted nature of the foreign policy process, rapid accumulation and processing of information, integration and regionalization, increased national consciousness of States, extensive interaction with non-state actors of international law. In the context of this long-term trend, the most important place belongs to the new actors of the foreign policy process that find themselves in the formats of international dialogue often more competitive as compared with formal, classic mechanisms of diplomacy. Thus, currently, public, economic, digital, sports, regional, scientific, and electoral diplomacy are actively manifested as key trends. The institution of parliamentary diplomacy plays a significant role in the implementation of foreign policy goals and objectives. The uniqueness of this diplomatic course is manifested in the fact that it organically combines the features of official diplomacy and public diplomacy, as parliamentarians act as legitimate representatives of their countries, elected through democratic procedures and representing the interests of their constituents. In the Russian Federation, parliamentary diplomacy is recognized as conceptually important, demanded and promising format of global interaction, which has been repeatedly mentioned at high level of the State.

Isolated Triggered Tremor Spots in South America and Implications for Global Tremor Activity
Authors: Chao Kevin , Peng Zhigang , Frank William B. , Prieto Germán A. , Obara Kazushige
Published: July 2019

We report new observations of triggered tectonic tremor in three regions in South America along the plate boundary between the Nazca and South America plates: southern Chile, Ecuador, and central Colombia. In these regions, tremor was observed during the passage of large‐amplitude surface waves of recent large earthquakes, which occurred in South America and around the world. In southern Chile, triggered tremor was observed around an ambient tremor active zone in the Chile triple junction region. In Ecuador and central Colombia, only one seismic station in each region recorded triggered tremor. With a single‐station approach, we are able to estimate potential tremor sources in these regions. Triggered tremor in Ecuador is likely associated with an inland fault near the volcanic region. In central Colombia, triggered tremor may be associated with the Romeral fault system rather than the subduction zone interface. In addition, we summarize global observations of tremor‐triggering stress and background ambient tremor activity in 24 tremor‐active regions. Based on the global summary of triggered and ambient tremor activity, the relative lack of triggered tremor in central and northern Chile and Peru is consistent with the lack of background tremor activity in these regions, suggesting tectonic tremor occurs only in isolated regions along major faults.

A ditadura franquista, desexando deslexitimar as políticas educativas republicanas, converteu o maxisterio primario en obxectivo prioritario da súa acción represiva, para o que articulou unha tupida rede de mecanismos destinados a purgalo e esixir responsabilidades. A depuración, co seu duplo carácter punitivo e preventivo, tivo o seu inicio de xeito inmediato ao golpe militar e durou ata a finalización da ditadura. Na primeira parte do artigo trazaremos as liñas xerais dos fundamentos ideolóxicos e legais da depuración, e exporemos as súas fases e os mecanismos utilizados. Na segunda, tras unha revisión das publicacións máis recentes, tentaremos un balance do estado da cuestión, detallando as porcentaxes de persoas sancionadas das provincias analizadas e mais a incidencia das variables territoriais de xénero e de renovación pedagóxica, así como algúns datos sobre o alcance da represió física do maxisterio. Concluímos reafirmando o carácter político e a arbitrariedade  do proceso depurativo.
O Proceso de depuración do maxisterio na provincia da Coruña
Authors: De Gabriel Narciso
Published: July 2019

Neste artigo ofrécese unha visión panorámica da depuración sufrida polo maxisterio público da provincia da Coruña entre 1936 e 1942, que conduciu á sanción dunha boa parte dos seus efectivos. Examínase primeiro a represión practicada polas autoridades militares e académicas, concentrada nos meses de agosto e setembro de 1936, e despois a realizada polo aparato especificamente depurador entre 1937 e 1942; diferénciase o alcance que tivo este proceso para mestras e mestres; descríbese a xeografía da represión, tomando o concello como unidade de análise; e revísanse os expedientes de depuración de Xos.éToba Fernández e de Palmira González López. As principais fontes utilizadas foron o Boletín Oficial do Estado e o Boletín Oficial da Provincia da Coruña, que permitiron cuantificar o proceso, e os expedientes de depuración, que resultan fundamentais para apreciar a súa dinámica e significado.
Política y educación en Antonio Gramsci
Authors: Trebisacce Nicola
Published: July 2019

El artículo, escrito con ocasión del 80 aniversario de la muerte de Antonio Gramsci, pretende subrayar la centralidad que el político italiano asigna a la cultura y a la educación en el proyecto de construir una alternativa a la sociedad burguesa. Y al repensar el marxismo a la luz de la nueva situación histórica italiana (e internacional), Gramsci identifica en la filosofía de la praxis y en la relación entre intelectuales y masas las condiciones para la construcción de una “cultura hegemónica” y un “principio educativo”, capaz entrenar al hombre nuevo (el Leonardo moderno) y realizar la sociedad comunista.

Published: July 2019

Aim: The aim of this study is to evaluate the clinical results of the patients undergoing off-pump and on-pump coronary artery bypass grafting (CABG) retrospectively in consideration of current literature.Material and Methods: A total of 1672 patients undergoing CABG between October 2014 and August 2016 and having a postoperative sinus rhythm were enrolled in the study. Patients who underwent an additional procedure in addition to CABG and underwent open heart surgery except CABG were excluded from the study. Off-pump CABG was applied to 783 and on-pump CABG to 889 of 1672 patients.Results: In comparison of operative data, duration of operation (p<0.001), number of bypasses to the coronary arteries (p<0.001), number of bypasses of the right coronary artery to the posterior descending artery (p<0.001), and diffuse coronary artery disease (p<0.001) were less in the off-pump CABG group and there was a statistically significant difference. In comparison of postoperative data, postoperative atrial fibrillation development (p<0.001), intubation time (p<0.001), intensive care unit stay (p<0.001), length of hospital stay (p<0.001), reexploration (p=0.006), vasopressor drug usage (p<0.001), positive inotropic drug usage (p<0.001), total drainage (p<0.001), blood and blood product used (p<0.001), and mortality rate (p=0.001) were less in the off-pump CABG group and statistically significant difference was found between groups.Conclusion: In this study, we found that off-pump CABG has many advantages. In a selected group of patients having a coronary artery disease performing CABG in beating heart would avoid the patient from morbid and mortal negative effects of cardiopulmonary bypass.
A vásárlói értékek és a gyenge elköteleződések az élelmiszerpiacon
Authors: Miklós Ilona
Published: July 2019

A dolgozat a hazai élelmiszerpiac védelmének értékdimenzióit az Európai Unió földrajzi eredetmegjelölési címkék (amelyek bizonyos élelmiszereket nemzeti tulajdonúként határoz meg) fogyasztói érték vizsgálatával elemzi. A kortárs élelmiszerpolitika és a szociológiai értékek vizsgálata több területre is kiterjed, beleértve az identitást, a hitelességet és a kultúrát, valamint a globalizáció hatásának összetettségét. Annak ellenére, hogy az élelmiszer központi szerepet tölt be az emberi lét fenntartásában, a fogyasztók általában nagyon keveset tudnak arról, hogy a vásárolt termék honnan származik, milyen környezeti és társadalmi költségekkel járt az elkészítésük, mivel a teljes globális élelmiszerrendszerek környezeti hatásainak nyomonkövetése összetett és komplex folyamat.  A dolgozat empirikus kutatással, sokdimenziós skálázással arra kereste a választ, hogy mitől válnak egyes élelmiszertermékek ismerté a hazai vásárlók körében, míg más termékek nem. A dolgozat eredményei alapján élelmiszerválasztás során a magyar vásárlók inkább kockázatkerülők nem pedig egészségmegóvók, ami nem erősíti hanem gyengíti a magyar élelmiszerrendszer hosszútávú fenntarthatóságát.

Modeling Spacetime as a Branched Covering Space over 2-Knots
Authors: Duston Christopher
Published: July 2019

In this paper we review a proposal to represent the geometric degrees of freedom of the gravitational field as a branched covering space, and introduce a new application of this in which the branch loci are 1- or 2-knots. This allows one to construct arbitrary smooth, closed 3- and 4-manifolds with enough geometric and topological information to write down a partition function and calculate statistical quantities in the thermodynamic limit. Further, we find clear evidence for a dimensional reduction of the spacetime geometry from four to two. As an example, we choose a family of smooth 4-manifolds presented in this way, and calculate the entropy of the system.

The Sakurajima volcano is characterized by frequent vulcanian eruptions at the Minamidake or Showa crater in the summit area. We installed an integrated monitoring system for the detection of volcanic ash (composed of remote sensing sensors XMP radars, lidar, and GNSS with different wave lengths) and 13 optical disdrometers on the ground covering all directions from the crater to measure drop size distribution and falling velocity. Campaign sampling of volcanic ash supports the conversion of particle counts measured by the disdrometer to the weight of volcanic ash. Seismometers and tilt/strain sensors were used to estimate the discharge rate of volcanic ash from the vents. XMP radar can detect volcanic ash clouds even under visual difficulty because of weather such as fog or clouds. A vulcanian eruption on November 13 was the largest event at the Sakurajima volcano in 2017; however, the volcanic plume was not visible due to clouds covering the summit. Radar revealed that the volcanic plume reached an elevation of 4.2–6.2 km. Post-fit phase residuals (PPR) from the GNSS analysis increased suddenly after the eruption, and large-PPR paths from the satellites to the ground-based receivers intersected each other at an elevation of 4.2 km. The height of the volcanic plume was also estimated from the discharge rate of volcanic ash to be 4.5 km, which is empirically related to seismic energy and the deflation volume obtained via ground deformation monitoring. Using the PUFF model, the weight of the ash-fall deposit was accurately forecast in the main direction of transport of the volcanic ash, which was verified by disdrometers. For further advances in forecasting of the ash-fall deposit, we must consider high-resolution wind field, shape of volcanic plume as the initial value, and the particle number distribution along the volcanic plume.

Lahar flow is recognized as among the worst secondary hazards from volcanic disaster. Intense rainfall with long duration is frequently associated with lahar flow. In this study, estimation of a rainfall threshold likely to trigger lahar flow is presented in the first part. The second part discusses its implementation by assessing the growth of observed and predicted rainfall, including the uncertainties. The study area is Merapi Volcano, one of the most active volcanoes in Indonesia, including rivers on the flank of Mount Merapi that are vulnerable to debris flow. The rainfall indices needed to describe the conditions that generate lahars or not were determined empirically by evaluating the hourly and working rainfall using X-band multiparameter (X-MP) weather radar. Using past records of lahar flow, the threshold lines separating rainfall that triggers lahars or not were analyzed for the Putih, Gendol, Pabelan, and Krasak Rivers. The performance of several critical lines was evaluated using Bayesian probability based on skill rates from a contingency matrix. The study shows that the line intercept of the critical lines after a significant eruption in 2010 was higher than those lines developed before 2010, indicating that the rivers are currently at lesser risk. Good representation was shown by the thresholds verified with actual rainfall progression and lahar event information on February 17, 2016, at the Gendol and Pabelan Rivers. These rainfall critical lines were the basis for judging the debris flow occurrence by analyzing the track record of predicted rainfall progression. The uncertainty of rainfall short-term prediction from the extrapolation model was evaluated by perturbing the advection vector of rain echo motion. This ensemble forecast product could provide a plausible range of prediction possibility as assistance in gaining the confidence with which a lahar could be predicted. The scheme presented herein could serve as a useful tool for a lahar early warning system in the area of the Merapi Volcano.
