Optimal ABox Repair w.r.t. Static EL TBoxes: from Quantified ABoxes back to ABoxes (Extended Version)
Authors: Baader Franz , Koopmann Patrick , Kriegel Francesco , Nuradiansyah Adrian
Published: March 2022

Errors in Description Logic (DL) ontologies are often detected when a reasoner computes unwanted consequences. The question is then how to repair the ontology such that the unwanted consequences no longer follow, but as many of the other consequences as possible are preserved. The problem of computing such optimal repairs was addressed in our previous work in the setting where the data (expressed by an ABox) may contain errors, but the schema (expressed by an EL TBox) is assumed to be correct. Actually, we consider a generalization of ABoxes called quantified ABoxes (qABoxes) both as input for and as result of the repair process. Using qABoxes for repair allows us to retain more information, but the disadvantage is that standard DL systems do not accept qABoxes as input. This raises the question, investigated in the present paper, whether and how one can obtain optimal repairs if one restricts the output of the repair process to being ABoxes. In general, such optimal ABox repairs need not exist. Our main contribution is that we show how to decide the existence of optimal ABox repairs in exponential time, and how to compute all such repairs in case they exist.
Carbon Dioxide Laser as a Sustainable Method for Producing a Pattern on Denim Fabric: Evaluation of Colour and Durability
Authors:   Manchester Fashion Institute, Faculty of Arts and Humanities, Manchester Metropolitan University, Cavendish Street, Manchester, UK, PD Venkatraman
Published: March 2022

Laser treatment of denim fabrics was demonstrated as one of the methods of producing distressed effects and is continuing to attract textile and fashion designers to develop bespoke designs that appeal to all age groups. Two dark shaded indigo-dyed 100% cotton twill fabric with varying weights representing various garment applications were laser treated using a commercially available pulsed CO2 laser of wavelength 10.62�m. Pulses per inch, which is the degree of closeness of laser irradiation, was maintained at 300 and 400 PPI. Treated denim fabrics were evaluated for tensile strength, colour measurements, including colour hue (H), saturation (S), brightness (B), reflectance, K/S (colour yield), CIE L* a* b*, fabric thickness and colourfastness after wash. Results indicated that colour contrast of denim fabric enhanced with the increase in grayscale (tone density) for both the LW (lightweight) and HW (heavyweight) fabrics, mainly at lower laser speed (80%) and higher laser power (40%). At higher grayscale (30% GS), surface fibers charred due to laser and the oxidation of cellulose occurred, causing a distinct yellow tone compared to pristine denim. Fabric tensile strength was affected as grayscale and laser parameters increased, the variation from pristine denim for LW fabric was 40 - 45% at 30% GS, whilst for HW fabric, variation was 25-30%. Colourfastness tests revealed limited colour staining, and it removed charred fibers showing a distinct tone change. This research recommends a combination of fabric and laser parameters to produce patterns without affecting the overall quality of the fabric.
Clathrate Hydrates Increase the Efficiency of Electrochemical CO2 Reduction
Authors: Lyu Mengjie , Li Ziyue , Bossche Maxime , Jónsson Hannes , Rose-petruck Christoph
Published: March 2022

When CO2 is encapsulated in clathrate hydrate, where the concentration is nearly two orders of magnitude greater than in saturated aqueous solution, the rate of the CO2 reduction reaction (CO2RR) increases, and the corresponding Faradaic efficiency becomes up to three times higher than that of the competing hydrogen evolution reaction (HER) at applied potential of -0.5 to -0.7 VRHE. The energy efficiency of the CO2RR is correspondingly increased. When the magnitude of the applied voltage is increased further the advantage of the clathrate encapsulation is diminished. The enhanced CO2RR in clathrate is ascribed to non-equilibrium release of the CO2 due to the electric field near the electrode, analogous to what has been observed recently for tetrahydrofuran [Li et al. J. Phys. Chem. Letters 125, 13802 (2021)]. This raises the chemical potential of CO2 beyond that of saturated aqueous solution, thereby reversing the relative rate of the CO2RR and the HER. The results reported here demonstrate this release mechanism for the application of CO2 up-conversion.
Understanding Current Density In Molecules Using Molecular Orbitals
Authors: Bro-Jørgensen William , C. Solomon Gemma
Published: March 2022

While the use of molecular orbitals (MOs) and their isosurfaces to explain physical phenomena in chemical systems are a time-honored tool, we show that the nodes are an equally important component for understanding the current density through single-molecule junctions. We investigate three different model systems consisting of an alkane, alkene and even [n]cumulene and show that we can explain the form of the current density using the MOs of the molecule. Essentially, the MOs define the region in which current can flow and their gradients define the direction current flows within that region. We also show that it is possible to simplify the current density for improved understanding by either partitioning the current density into more chemically intuitive parts, such as σ- and π-systems, or by filtering out MOs with negligible contributions to the overall current density. Our work highlights that it is possible to infer a non-equilibrium property (current density) given only equilibrium properties (MOs and their gradients) and this, in turn, grants deeper insight into coherent electron transport.
Four-dimensional spacetime atomistic artificial intelligence models
Authors: Ge Fuchun , Zhang Lina , Ullah Arif , Dral Pavlo O.
Published: March 2022

We demonstrate that artificial intelligence (AI) can learn four-dimensional (4D) atomistic systems in the spacetime continuum. Given the initial conditions – nuclear positions and velocities at time zero – the proposed 4D-atomistic AI (4D-A2I) models can predict nuclear positions at any time in the future or past for the simplest systems as we show for H2. For larger polyatomic molecules, AI is capable of learning distant but finite future as we demonstrate for an ethanol molecule. 4D-A2I models provide direct access to a multitude of properties at a given time such as geometries, velocities, forces, and energies which can be used in simulating physicochemical transformations and spectra. Our approach can be used as a cost-efficient alternative to traditional molecular dynamics. We show an example of a 4D-A2I model describing the dynamical behavior of ethanol at the coupled-cluster level with the speed of one nanosecond simulation time per one hour wall-clock time on a single GPU card – a previously unachievable feat with traditional Born–Oppenheimer molecular dynamics. 4D-A2I model is also demonstrated to provide direct access to atomistic time-resolved details of physicochemical transformations.
Optical Spectra of Plasmon--Exciton Core--Shell Nanoparticles: A Heuristic Quantum Approach
Authors: Stete Felix , Koopman Wouter , Henkel Carsten , Benson Oliver , Kewes Günther , Bargheer Matias
Published: March 2022

Light--matter coupling in plasmonic nanocavities has been widely studied in the past years. Yet, for core--shell particles, popular electromagnetic models that use the classical Lorentz oscillator to describe the shell predict extinction spectra with three maxima, if the plasmon and the shell absorption are in resonance. In contrast, experiments exhibit only two peaks as also expected from simple quantum models of hybrid states. In order to reconcile the convenient and widely used classical electromagnetic description with experimental data, we connect it to the quantum world by conceiving a heuristic quantum model. Our model is based on the permittivity of a two-level system in a classical electric field derived from the optical Bloch equations. The light--matter coupling is included via the collective vacuum Rabi frequency $\Omega_0$. Using our model, we obtain excellent agreement with a series of experimental extinction spectra of particles with various coupling strengths due to a systematic size variation. The suppression of the third maximum, which mainly stems from the absorption in the shell, can be interpreted as a vacuum induced power broadening, which may occur in lossy (plasmonic) cavities below the strong-coupling regime.

Background. A low hemoglobin level in older adults impairs cognitive ability and functional status and associates with risk of falls and fractures, sarcopenia, malnutrition, depression, frailty, and decreased autonomy. Epidemiological data on the anemia prevalence in the geriatric population in our country is not available.
Aim. To assess the prevalence of anemia and analyze its associations with geriatric syndromes (GS) in subjects aged 65 years.
Materials and methods. 4308 subjects (30% of men) aged 65107 years, living in 11 regions of the Russian Federation, were examined and divided into age groups (6574 years, 7584 years and 85 years). All the participants underwent a comprehensive geriatric assessment and determined hemoglobin level.
Results. The anemia prevalence in older adults was 23.9%. It has been shown that with an increase in age per 1 year, the risk of anemia detection increases by 4%. The incidence of anemia was higher in males than females (28.1% versus 22.1%; p0.001). In most cases, anemia was mild. The results of a comprehensive geriatric assessment show that patients with anemia had lower hand grip force, Barthel Index, the sum of points on Lawton instrumental activities of daily living scale, Mini Nutritional Assessment scale, the Mini-Cog test and higher the sum of points on the Geriatric Depression Scale (GDS-15) and the Age Is No Barrier scale. Patients with anemia were more likely to use hearing aids, absorbent underwear, and assistive devices during movement. Patients with anemia had a higher incidence of all GS, except for orthostatic hypotension and chronic pain syndrome. The presence of GS is associated with an increased risk of anemia by 1.33.4 times.
Conclusion. EVKALIPT study obtained domestic data on the prevalence of anemia in older patients and examined its associations with other GS.

Authors: Aksenova Anna V. , Oschepkova Elena V. , Chazova Irina E.
Published: March 2022

Aim. To analyze therapy in patients with arterial hypertension (AH) in 20102020. Materials and methods. Data of hypertensive patients observed in primary health care, entered into the base of hypertension registry for 20102020 years in the whole group (n=44 653) and in a separate subgroup of hypertensive patients in the absence of: ischemic heart disease, a history of myocardial infarction, chronic heart failure (n=20 569). Results. About 80% of hypertensive patients are patients of high and very high risks (from 2010 to 2020, the proportion of very high cardiovascular risk (CVR) increased from 18.1 to 57.3%). The number of hypertensive patients with a history of myocardial infarction increased in 5 times, in 3 times with ischemic heart disease and with chronic heart failure. The number of prescribed drugs increased: mineralocorticoid receptor antagonist (in 5.8 times), loop diuretics (in 7.2) angiotensin receptor blockers (in 3 times), b-adrenoblockers, calcium channel blockers of the dihydropyridine series, thiazide-like diuretics in 2 times. Patients at high and very high risk are more likely reached target blood pressure values. Angiotensin-converting enzyme inhibitors were prescribed in more than 70% of patients with hypertension and the absence of coronary heart disease, chronic heart failure, history of myocardial infarction; the prescription of b-adrenoblockers, angiotension receptor blockers, thiazide-like and loop diuretics increased. Conclusion. The proportion of more severe and comorbid patients has increased in observed in primary health care patients with AH over a 10-year period (20102020). This was probably the main factor of increasing antihypertensive therapy and prescribing drugs with additional indications and improving the achievement of target blood pressure in patients with high and very high cardiovascular risk.

In the paper, the stochastic method of global extremum search is discussed, modified and tested. The method is based on normal distribution modeling and provides covariance matrix adaptation. The method is iterative; a genetic algorithm has been developed on its basis. The coordinates of the trial points of each generation are determined using the ”best” points of the previous generation and the values of standard normal random variables. Thus, at each stage of the search, a normal distribution is simulated, and its parameters (the mean and the covariance matrix) are estimated through the positions of the ”best” points of the previous generation. In this case, there is no need to calculate, store and transform the covariance matrix, which is indisputable advantage of this method. Practice has shown that the dispersion ellipsoid of normal distribution shrinks rapidly with generation number increasing, which can lead to an excessive narrowing the scanning area and obtaining a local extremum instead of a global one. The proposed modification of the method avoids this situation. The trial points are divided into two groups, which are simulated using normal random variables with different standard deviations, at least one of which is greater than 1. Thus, a kind of mutation of the population is carried out, which makes it possible to provide a sufficient number of sample points both near the “best” one and at a distance from it. The modified genetic algorithm is applied to solving the problem of estimating the parameters of nonlinear parametric regression. A successful minimization of the multiextremal function is performed. The stochastic method is used in combination with directional. The numerical results presented confirm the effectiveness of the introduced modification of the genetic algorithm and make it possible to choose from two directed methods the more efficient one for the problem under consideration

Published: March 2022

This research aims to find out correlation between grammar and speaking skill of the third semester students of English Education Study Program academic year 2019/2020 at IAIN Datokarama Palu. 28 participants of correlational research were asked to describe themselves, daily routines, and unforgettable experience. Then, they were assigned to do grammar test. The data were analyzed using Pearson Product Moment Correlation Coefficient. The result shows that the correlation coefficient between students’ grammar and speaking skill is 0.46. The result is categorized “moderate” (0.40 to 0.59). It indicates that there is positive correlation between the students’ grammar and speaking skill which means that grammar contributes to speaking skilll, but grammar is not the main predictor of speaking skill achievement. There are some other aspects of speaking affecting the students’ speaking skill, i.e accuracy (in terms of vocabulary and pronunciation), fluency, and comprehensibility. The implication of this finding to the teaching of speaking skill is that the lecturers need to integrate the teaching of speaking skill with grammar and other supporting aspects, like vocabulary and pronunciation.

Published: March 2022

La anestesia es un tratamiento médico que se emplea en los pacientes para evitar que sientan dolor al momento de alguna intervención quirúrgica. Los tipos de anestesia utilizados son: la anestesia general que afecta todo el cuerpo y hace que los pacientes estén inconscientes y no puedan moverse y la anestesia regional que se usan en cirugías de manos y articulaciones, disminuye el dolor de un parto o cesárea. El manejo cuidadoso de las vías respiratorias, incluida la intubación traqueal, es importante al momento de realizar un procedimiento con anestesia para lograr una intubación segura en el cuidado de dicho procedimiento, tanto desde la perspectiva del profesional como del paciente. A través de la escala de Mallampati se puede realizar una buena prueba de detección para predecir la intubación fácil siendo realizada de manera segura por los anestesistas. Los algoritmos pueden entenderse como reglas parecidas a leyes, un plan preciso a seguir en situaciones de vías respiratorias difíciles, un plan de acción que se mantiene en mente mientras se crean algoritmos personales flexibles y versátiles, o como pautas de consenso basadas en la opinión de expertos para ser seguida en la práctica clínica. Los algoritmos deben ser simples y fáciles de seguir y deben basarse en la mejor evidencia científica disponible.
Neumonía asociada a la ventilación mecánica en pacientes COVID
Authors: Montero Loayza Karina Mercedes , Reina Pizarro Ricardo Gutember , Aguilar Luzuriaga Carlos Julio , Díaz Recalde Eddy Xavier
Published: March 2022

La enfermedad por COVID-19 o novel coronavirus, es una pandemia global de enfermedad respiratoria aguda causada por este virus, que filogenéticamente está estrechamente relacionado con SARS-CoV. La dificultad respiratoria es más característica de neumonía. Este comienza con oxígeno suplementario, uso restrictivo de fluidos y administración de antimicrobianos empíricos por una eventual coinfección bacteriana. Los pacientes sintomáticos respiratorios deben ser aislados y estrechamente monitoreados debido a la posibilidad de progresión rápida y fulminante de la falla respiratoria. Actualmente se recomienda la intubación temprana de los pacientes afectados severamente con COVID-19. La proporción de pacientes con COVID-19 a los que se les diagnostica Síndrome de dificultad respiratoria aguda (SDRA) según criterios de oxigenación, oscila entre el 20% y el 67% en los pacientes ingresados hospital y es casi del 100% en los pacientes con ventilación mecánica. El objetivo de la investigación es conocer las características encontradas en pacientes con COVID-19 diagnosticados con neumonía y la asociación de la misma con la ventilación mecánica. Para alcanzar los objetivos se ha de realizar la búsqueda a través de Google Académico de las publicaciones científicas que describen la neumonía asociada a la ventilación mecánica incluyendo los hallazgos antes y después de la COVID-19. Luego de analizar la información encontrada se exponen los extractos que se consideren, aportan una visión completa y concreta acerca del tema planteado. Se puede concluir que la neumonía en pacientes con covid-19 no necesariamente está asociada a la ventilación mecánica. Según los hallazgos, los pacientes diagnosticados con COVID-19 llegan a necesitar soporte mecánico respiratorio una vez que presentan un SDRA, por lo tanto, la neumonía ya existe para ese momento. Aun cuando la sobreinfección es posible, no existe suficiente evidencia para adjudicar a la ventilación mecánica las neumonías desarrolladas por los pacientes con una fase moderada a grave por infección con el SARS-Cov-2.

Creation of a representative climatological database for Hungary from 1870 to 2020

Published: March 2022

Climate studies, particularly those that are related to climate change, require long, high-quality controlled data sets, which are representative both spatially and temporally. Changing the conditions of measurements, for example relocating the station, or changing the frequency and timing of measurements, or changing the instruments used can cause breaks in the time series. To avoid these problems, data errors and inhomogeneities are eliminated and the data gaps are filled by using the MASH (Multiple Analysis of Series for Homogenization, Szentimrey, 1999, 2008) homogenization procedure. The Hungarian meteorological observation network was upgraded significantly in the last decades. Homogenization of the data series raises the question of how to homogenize long and short data series together within the same process. It is possible to solve this with the MASH method due it has solid mathematical foundations, which make it suitable for such purposes. The solution includes the synchronization of the common parts’ inhomogeneities within three (or more) different MASH processing of the three (or more) datasets with different lengths depending on the time periods and elements. After the homogenization process, the station data series were interpolated to a 0.1 degree regular grid covering the whole area of Hungary. The MISH (Meteorological Interpolation based on Surface Homogenized Data Basis; Szentimrey and Bihari, 2007) program system was used for this purpose. The MISH procedure was developed specifically for the interpolation of various meteorological elements. In the case of mean temperature, we also renewed the MISH modeling, as compared to previous years, the number of homogenized stations doubled due to the new work, so it was expedient to model the climate statistical parameters with this extended station system. Time series of daily mean temperature and precipitation sum for the period 1870–2020 for Hungary were used in this study. As a result, the longest ever homogenized, gridded daily data sets became available for Hungary.

Protective Measures to Enhance Human Longevity and Aging: A Review of Strategies to Minimize Cellular Damage
Authors: Umesh C. Gupta  , Subhas C. Gupta

Aging is a universal process in all life forms. The most current and widely accepted definition of human aging is a progressive loss of function and energy production that is accompanied by decreased fertility and increased mortality with advancing age. The most obvious and commonly recognized consequence of aging and energy decline is a decrease in skeletal muscle function, which affects every aspect of human life from the ability to walk and run, to chew, and swallow and digest food. Some crucial factors responsible for aging and longevity include genetics, environment, and nutrition, serious disease disorders such as cancer and cardio-vascular diseases, sarcoma and cell senescence. Oxidative damage caused due to the accumulation of molecular waste-by-products of the body’s metabolic processes, which our bodies are unable to break down or excrete, is chiefly responsible for aging and diseases. Regular physical activity, consumption of foods rich in phytochemicals and anti-oxidants, cessation of smoking, avoiding foods high in saturated and hydrogenated fats are some of the strategies that should be taken into account to delay aging and prolong longevity.
AASL National School Library Standards: Progress toward Implementation
Authors: Burns Elizabeth
Published: March 2022

This mixed-methods, exploratory case study examines perceptions of the implementation of the U.S. National School Library Standards for Learners, School Librarians, and School Libraries. A survey was first distributed to gain insight into school librarian implementation of the NSLS. Participants included practitioners in the state of Virginia in the United States who had attended professional development training on the National School Library Standards (NSLS). A sample was then interviewed about their implementation. Using the standards implementation levels identified by the California Common Core Implementation Task Force (2019) as a framework, findings indicate that after one year of training and use, many librarians remain at the awareness phase of implementation. Findings do suggest some areas in which practitioners have shown progress as they implement the standards into practice. Finally, common challenges or barriers to implementing the NSLS are noted. Future directions for research and recommendations for training at both the school/district level and national organization level are suggested.
Teachers' Attitudes Toward Library Use
Authors: Golden Jonathan
Published: March 2022

The purpose of this mixed-method study was to explore attitudes of high school teachers toward the use of the school library by students to complete research projects. Public high school teachers were surveyed (N=81) about their attitudes toward student use of the school library. Statistical analyses revealed no significant differences among teaching disciplines nor between genders. Tests also revealed no correlation between survey responses and time teaching. Interviews were conducted to further explore attitudes toward student library use. Interview results suggested that teachers considered the library useful in the completion of research projects but were reluctant to require students to the library. The results suggested that strategies are necessary to mitigate reluctance to include school library resources as a component of assigned research projects.
Rethinking Curation in School Libraries and School Library Education: Critical, Conceptual, Collaborative
Authors: Spiering Jenna , Lechtenberg Kate
Published: March 2022

School library educators often assign a curation assignment to preservice school librarians in the university classroom. However, these projects emphasize a product created by librarians for teachers and learners, rather than the collaborative and critical process that the National School Library Standards suggest. In this paper, we draw on data from a qualitative inquiry of several courses for preservice school librarians, looking at both curation assignment descriptions and the final products. Through a systematic content analysis of these projects, we have found that these assignments often fall short in asking our learners to critically consider conceptual connections and diverse perspectives. To this end, we identify revisions to these assignments that reframe curation as a collaborative, conceptual, critical endeavor.
Factors Influencing Intention to Introduce Accessibility in Makerspace Planning and Implementation
Authors: Moorefield-Lang Heather , Dubnjakovic Ana
Published: March 2022

Makerspaces continue to grow in popularity in public, academic, and school libraries. As makerspaces are included in library services, accessibility for all users is important. What motivates a school librarian to implement a makerspace accessible to all learners? Are they more likely to invest in accessibility if provided the necessary resources? In this study, researchers discuss which Theory of Planned Behavior (Ajzen 1985) variables significantly predict school librarians’ intentions to implement accessible makerspaces. Researchers also delve into how attitude towards accessibility in makerspaces influence the intention to implement accessible makerspace. Findings indicate identifying perceived behavior control is the principal predictor of behavioral intention. Additionally, identifying makerspace accessibility as a top priority and agreeing that it should be accessible might be different in the minds of school librarians.

This study aims to analyze the school's collaboration with industry and business community (DU/DI) in improving the quality of Vocational High School (SMK) graduates. This study applies a qualitative descriptive approach of case study design at SMK Negeri 3 Jayapura. The researcher as the key instrument of the research conducted an in-depth interview with principals, teachers/public relations, students, school committees, supervisors as well as industry and business community (DU/DI). Participatory observation and document analysis were also utilized in order to support the data gathering process. The techniques for validating the data were gathered by extending the time of observation, peer discussion and triangulation. The data was analyzed qualitatively by means of data reduction, data display, and drawing conclusions/verification. The results of this study indicate that the school's collaboration with industry and business community (DU/DI) in improving the quality of SMK Negeri 3 Jayapura is favorable but still needs some improvement. It still requires some adjustments in term of alignment of the data-based industry-based curriculum which involves industry and business community (DU/DI) from its early establishment, the presence of industrial teachers which has not yet touched the substance of industrial practice and the absorption of graduates is still limited to MoUs bound by contracts and high-achieving graduates.
Café Culture in French Painting in the Second Half of the 19th Century
Authors: ÇAPAR Mustafa
Published: March 2022

On yedinci yüzyılda kahve kullanımının Avrupa'da yaygınlaşmasından sonra kahvehaneler günlük yaşamın önemli bir parçası haline gelmiştir. Önceleri yalnızca kahve içilen yerler iken sonraları alkollü içkilerin de sunulmaya başladığı
kahvehanelerin adları da pek çok yerde kafe olarak değişmeye başlamıştır. Londra ve Paris başta olmak üzere Avrupa’nın pek çok şehrinde kafeler insanların bir arada bulunabildikleri kamusal alanlar olmuşlardır. Özellikle 19. yüzyılın
ikinci yarısında, şehrin yeniden düzenlenmesiyle birlikte Paris kafeleri modern yaşamın vazgeçilmez mekânlarından biri olarak hizmet vermiştir. Bazıları şehrin daha çok işçi sınıfından olan yoksulların yaşadığı mahallelerinde yaşayan
sanatçılar için bu tür kafeler Paris’in modern yüzünü görmelerini sağlamıştır. İçlerinde sanatçıların, şair ve yazarların, eleştirmenlerin, fotoğrafçıların olduğu pek çok insan, 1860’lı yılların ortalarında Edouard Manet’nin önderliğinde
Café Guerbois’de toplanmaya başlamıştır. Bu toplantılar, sanatçıların başka sanatçılarla tanışmasını sağlamış, sanat konularında yapılan entelektüel tartışmalar dönemin hâkim sanat kurumlarına bir alternatif oluşturmuştur. Yakın
gelecekte kurulacak olan İzlenimciliğin tohumları bu buluşmalarda atılmıştır. Zamanla Café Guerbois’den uzaklaşan bu çevre sonrasında Café de la Nouvelle-Athénes’de toplanmaya başlamıştır. Bu araştırmada, 19. yüzyılın ikinci yarısında,
Fransa’da kafelerin sanatçılar için sosyalleşme, fikir alışverişinde bulunma, tartışma ve etkinlikler planlama gibi olanaklar sunması ile sanatçıların sanatsal bir konu olarak kafe ortamını çalışmalarında ele almaları incelenmiştir.
Sonuç olarak, kafelerin söz konusu dönemde, özellikle Paris’te sanatçıların birbirleriyle diyalog kurmalarına ve modern yaşamı resmetmelerine önemli katkılar sağladığı görülmüştür.

Prediction of season onset is important for many sectors, particularly on agricultural practices, as its usage for reducing climate risk and planning activities. Current knowledge on season onset prediction mainly focused on large area, which remains research challenge for local level. This research developed model prediction of season onset for Malang Regency, East Java based on global climate data. The research specifically aimed to: (i) determine the onset date of rainy and dry season, (ii) generate equation for onset date prediction using principal component regression (PCR) approach, and (iii) evaluate the model performance. We depend on statistical model based on a combine of domain time and principal component analysis (PCA) for atmospheric variables, namely sea level pressure, outgoing longwave radiation, and zonal wind. We used the Tropical Rainfall Measuring Mission (TRMM) data for model evaluation, especially for determination of onset date. Based on cumulative anomalies rainfall, the onset date for dry season occurred in the early May, whereas for rainy season it was in early November. The results showed that regression models of the principal components had a good skill to predict onset date for both seasons. It has been confirmed by a low error and a high correlation. Visually, the dynamic of onset dates from model was mostly identical to the observation. The predictive model for rainy season had higher performance compared to the model for dry season. This finding was confirmed by insignificant difference resulted from the independent t-test between model and observed onset dates. The best model for dry season was conducted by domain time of February, whereas for rainy season was domain time of August. This research can be used to complement previous studies regarding season onset prediction in Indonesia.
