Desain Pengembangan Kurikulum Pendidikan Agama Islam
Authors: Mahrus Mahrus
Published: July 2021

Design can be formulated as a deliberate process of thinking, planning and selecting the parts, techniques, and procedures that set a goal. Challenges to Islamic religious education include a moral crisis and a personality crisis. Therefore, Islamic religious education is required to be able to equip students with the moral, personality, quality and maturity of life to live a multi-cultural nation life, which is currently hit by an economic crisis in order to livepeacefully in the world community.In an effort to develop an Islamic education curriculum to overcome various challenges and problems, it is necessary to pay attention to several aspects including strategies, methods, materials, Islamic religious teacher resources, facilities, teaching media and supporting instruments.Taking into account the demands of the globalization era of Islamic religious education in madrasas and public schools, it is necessary to implement several strategies, including: First, perfecting the religious education curriculum so that the subject matter reaches a proportional and functional composition but does not burden students. Second, combining religious material with character education materials such as PPKn or other related subjects can also erode thedichotomy of knowledge. Third, creating a religious condition in the school environment

Authors: Chatterjee Subhojit , Hasan Usra , Chatterjee Subhra
Published: July 2021

Introduction: Physiological and body composition variables have important role for assessment of training status and evaluation of health status of athletes. Regular monitoring of these variables during training may provide valuable information to coaches for training and selection of players’ training protocol participating in both team sports and individual events. Purpose and objectives of the study: The aims of this study were to compare physiological and body composition variables between male athletes participating in team sports (football) and individual sprint event and also to correlate training duration (both in years and hours per week) of male athletes participating in both team sports as well as sprint with physiological and body composition variables. Applied Methodology: The study was carried out with thirty-year-old (n=30) and BMI matching male Indian athletes participating in team sports (football, n=16) and individual sprint event (n=14), having minimum 2 years of official training. They were in post competitive phase during the test. Several physiological and body composition variables were assessed such as height, weight, body mass index, training age (years), training time (hours/week), fat mass, fat-free mass, body cell mass, muscle mass, VO2 max, maximal power, training intensity and fatigue index following standard protocol. Achieved major results: The sprinters were found to possess significantly more fat-free mass (p < .01), body cell mass (p < .01), muscle mass (p < .01), less fat mass (p < .05) and more average anaerobic power (p < .01) than their peers - football players. However, no significant correlation was found between any of the measured physiological and body composition parameters and the training status of these players. Conclusion: This study would provide useful information for assigning training protocols to the athletes participating in team sports and individual sprint events on the basis of physiological and body composition parameters.
KINEMATIC DIFFERENCES BETWEEN PROFICIENT AND NON-PROFICIENT FREE THROW SHOOTERS – VIDEO ANALYSIS
Authors: Cabarkapa Dimitrije , Fry Andrew , Poggio John , Deane Michael
Published: July 2021

Despite its importance and significant contribution to the final game outcome, the free throw shooting motion is greatly understudied. The purpose of this study was to examine kinematic differences between proficient and non-proficient free throw shooters and to determine which variables have the greatest impact on successful free throw shooting performance. Thirteen healthy recreationally active males volunteered to participate in this study. Each participant shot three sets of ten consecutive free throws from the regulation distance from the basket. Each set was performed under 3 minutes with 1-2-minute rest between each set. A high-definition camera recording at 30 fps captured the free throw shooting motion from a sagittal point of view. Video analysis software was used to analyze the following kinematic variables: knee angle, elbow angle, hip flexion, ankle flexion, release angle, shoulder angle, hand release height, and elbow height. The findings of this study suggest that lower elbow positioning influenced by greater knee, ankle, and hip flexion during the preparatory phase of the shooting motion may lead to improvements in free throw shooting accuracy. Moreover, greater ball release height and release angle, as previously suggested, could decrease the margin of error and enhance free throw shooting performance. By using these kinematic variables to create the discriminant function projection model, it is plausible that proficient free throw shooters can be accurately classified in 94% of cases.

Published: July 2021

The 1985 expedition constitutes the first comprehensive investigation of the isolated, hyperarctic semi­nunatak Kilen in eastern North Greenland. Well over 3 km of generally marine, elastic sediments are preserved from the Late Jurassic to Late Cretaceous period. While half this amount accumulated in ·a comparatively stable tectonic regime prevailing during Late Jurassic and Early Cretaceous time, the Late Cretaceous (Turonian-Coniacian) sediments are characterized by their deposition in a local pull-apart basin developed in the regional Wandel Hav Strike-Slip Mobile Belt. Subsequent, localized compression along this belt has deformed the entire sequence rather severely in a complex series of en echelon domal folding and thrusting, most likely during the later part of the Cretaceous. Quaternary marine sediments of probable interglacial origin (> 100.000 years old) have been found to contain a mollusc fauna requiring temperatures above the present level. Flade lsblink, the largest local icecap in Greenland, is composed of several semi-independant ice domes, and there is evidence that the history of this icecap deviates significantly from that of the Inland Ice. A total of 34 species of higher plants, 29 species of birds, and 11 species of mammals have been recorded from Kilen; vegetation studies indicate a July mean temperature of around 2.5°C.

(Phyl­/optychoceras) sp., Baculites knorrianus Desmarest, 1817, B. vertebra/is Lamarck, 1801, Baculites species 1, 2 and 3, Acanthoscaphites tridens (Kaer, 1848), A. varians (Lopuski, 1911), Hop/oscaphites constrictus (J. Sowerby, 1817) and H. tenuistriatus (Kner, 1848), and their ranges documented in terms of existing brachiopod and belemnite zonations. Seven taxa, representing the Phylloceratina, Lytoceratina, Ammon­itina and Ancyloceratina, extend to the high Maastrichtian at Stevns Klint. There are no indigenous Danian ammonites; specimens found in the basal Danian are derived from the underlying Maastrichtian.

Authors: Dimitrov Lyobomir I. , Dontcheva Valentina G.
Published: July 2021

ockmarks were discovered for the first time in the SE of the Bulgarian Black Sea zone in 1988. Echo sounder and shallow seismic data analyses of investigations conducted before and after 1988, allow the main pockmark area to be enlarged and given more details. A total of 305 pockmarks have been located within an area of more than 100 km2 (2-5 km wide and 41 km long). The bottom of the area is covered with Holocene soft silty clay. The following trends are defined when moving from the northern part of the pockmark area to the southern part: 1) increase in seabed sediments thickness from 2.5 m to more than 3.2 m and decrease in mean sediment grain size; 2) increase in general water depth from 160-300 m to 230-340 m in areas where pockmarks occur; 3) increase in average individual pockmark size from 86 to 132 m in diameter and from 2 to 4 m in depth; 4) decrease of pockmark density from 8-9 p.m./km2 to 3-4 p.m./km2 Similar trends are observed seaward where the pockmark profile shape changes from a smooth U-shaped to a sharp V-shaped form, with pockmark wall slope angle reaching more than 10°. A variety of acoustic anomalies such as acoustic turbidity, bright spots, enhanced reflections etc., are recorded in many places within the pockmark area, indicating the presence of gas in the sediments. Water column anomalies have also been recorded. The paper discusses the origin of the gas (most likely to be a mixture of thermogenic and biogenic gas) and the time of pockmark formation.
The Affective Aspect of the “Poetics — Poetry — Translation” Paradigm
Authors: Колкер Я.М. , Устинова Е.С.
Published: July 2021

В статье с переводческой позиции рассматривается эмоциональный эффект, производимый короткими стихотворениями о Великой Отечественной войне. Предметом исследования является выразительность, понимаемая не как экспрессивность тропов, фигур речи или авторских окказионализмов, а как эффект воздействия на читателя, достигаемый всей совокупностью средств письменного художественного текста. Особое внимание уделяется неброским проявлениям выразительности, приобретающим смысл только в конкретном тексте. Исследуется взаимодействие и взаимозависимость лексических, синтаксических, фонетических и пунктуационных способов выразительности, их смысловой потенциал, пути достижения компрессии, а также способы передачи создаваемого впечатления в переводе. Авторы предлагают свое видение основной задачи поэтики в отношении поэтических произведений с присущей им компрессией, где любая самая мелкая единица текста, включая знаки пунктуации, участвует в создании тона, авторского голоса и производимого эмоционального впечатления. Исследование выполнено на материале четырех стихотворений отечественных классиков середины ХХ века — А. А. Ахматовой, А. Т. Твардовского, К. М. Симонова и А. А. Тарковского. Переводы стихотворений на английский язык сделаны авторами статьи.

The paper examines, through the lenses of a translator, the emotional effect produced by short poems about the Great Patriotic war. The study focuses on the notion of expressiveness, but not the kind of expressiveness that catches the eye with original tropes and figures of speech or the author’s nonce-words. It is treated as the effect produced upon the reader by a whole array of descriptive and expressive means employed in written texts. The authors examine the interaction and interdependence of lexical, syntactical, and, especially, less conspicuous phonetic and punctuation means of meaning-making. It is stated that a compressed and unaffected manner of expression in poetry may have a far greater impact than an excessive use of tropes or most inventive nonce-words. The authors suggest their vision of poetics in reference to poetry, with its tendency for compression, where every component, however unobtrusive (like punctuation signs, for instance), participates in creating the right tone, in rendering the poet’s voice and producing the intended emotional impression. The research is based on four Russian poems written in the 1940’s–1970’s by Anna Akhmatova, Alexander Tvardovsky, Konstantin Simonov, and Arseny Tarkovsky. The translations belong to the authors of the paper.

Kampung 1001 Malam adalah sebuah pemukiman padat di bawah jembatan tol Dupak Surabaya. Dinamai demikian mengingat kondisi pemukiman yang selalu gelap karena kurangnya cahaya di kampung itu. Selain selalu berada dalam suasana malam (gelap), kampung tersebut kumuh dan tak tersentuh pembangunan. Kampung ini dihuni oleh warga yang rata-rata bekerja sebagai pemulung, buruh bangunan, atau pengemis. Kelompok marjinal yang terpinggirkan dari akses ekonomi, sosial, dan politik. Suatu ironi mengingat keberadaannya yang tepat di bawah simbol pembangunan kota, jalan tol. Artikel ini merupakan hasil penelitian yang mengawali program pengabdian masyarakat mahasiswa Stikosa-AWS berupa pembuatan video dokumenter tentang Kampung 1001 Malam. Selain video tersebut mahasiswa juga memberikan paket bantuan pendidikan kepada warga. Meski terbatas, dua pilihan kegiatan tersebut terpaksa diambil karena program pendidikan gratis bagi anak-anak putus sekolah di kampung itu tidak dapat dilaksanakan akibat pandemi.

Background & Aims: Chronic hepatitis B (CHB) infection can cause liver cirrhosis and hepatocellular carcinoma. In this study, it was aimed to evaluate the efficacy of tenofovir disoproxil fumarate (TDF) and tenofovir alafenamide fumarate (TAF) on clinical parameters, glomerular filtration rate (GFR), and phosphorus metabolism in the patients with CHB.

Materials and Methods: Eighty-one patients with CHB treated with TDF were included in the study. 27 of them switched from TDF to TAF during the follow-up was considered as TAF group. 54 patients continued TDF were evaluated as TDF group. Demographic, clinical, and laboratory data of the patients were obtained from outpatient follow-up files.

Results: The mean ages of the patients were 45±12 and 48±15 in the TDF and TAF groups, respectively. The mean durations of TDF treatment were 31±20 and 52±32 months, respectively. The mean duration of TDF use was significantly higher in the TAF group (0.01). The mean aspartate aminotransferase (AST), alanine aminotransferase (ALT), GFR, and serum phosphorus levels of the patients before/after the TDF treatment were 48/23 U/L, 67/25 U/L, 99/103 ml/min, and 2.9/3.1 mg/dl in the TDF group, respectively. The mean AST, ALT, GFR, and serum phosphorus levels of the patients before the TDF treatment/at the time of the switch/after the TAF treatment were 42/22/21 U/L, 48/23/22 U/L, 90/100/102 ml/min, and 2.8/2.3/2.9 mg/dl in the TAF group, respectively. Decrease in the mean values of the transaminases after the TDF treatment in the both groups and increase in the mean level of phosphorus after the switching were found significant (p

Under certain conditions on the given data we proved that the inverse problem is locally well-posed in the sense of Hadamard. Our method of proof based on eigenfunction expansion for which the eigenfunctions (which are Mittag-Leffler functions) of fractional order spectral problem and its adjoint problem are considered. Several properties of multinomial Mittag-Leffler functions are proved.
A Red Giant Branch Common-envelope Evolution Scenario for the Exoplanet WD 1856 b
Authors: Merlov Ariel , Bear Ealeal , Soker Noam
Published: July 2021

We propose a common-envelope evolution scenario where a red giant branch (RGB) star engulfs a planet during its core helium flash to explain the puzzling system WD 1856+534, where a planet orbits a white dwarf (WD) of mass M
WD ≃ 0.52 M
⊙ with an orbital period of P
orb = 1.4 days. At the heart of the scenario is the recently proposed assumption that the vigorous convection that core helium flash of RGB stars drive in the core excite waves that propagate and deposit their energy in the envelope. Using the binary-mesa stellar evolution code we show that this energy deposition substantially reduces the binding energy of the envelope and causes its expansion. We propose that in some cases RGB stars might engulf massive planets of ≳0.01 M
⊙ during their core helium flash phase, and that the planet can unbind most of the mass of the bloated envelope. We show that there is a large range of initial orbital radii for which this scenario might take place under our assumptions. This scenario is relevant to other systems of close sub-stellar objects orbiting white dwarfs, like the brown dwarf–WD system ZTFJ003855.0+203025.5.
A mathematical perspective on radar interferometry
Authors: Gilman Mikhail , Tsynkov Semyon
Published: July 2021

Radar interferometry is an advanced remote sensing technology that utilizes complex phases of two or more radar images of the same target taken at slightly different imaging conditions and/or different times. Its goal is to derive additional information about the target, such as elevation. While this kind of task requires centimeter-level accuracy, the interaction of radar signals with the target, as well as the lack of precision in antenna position and other disturbances, generate ambiguities in the image phase that are orders of magnitude larger than the effect of interest.

Yet the common exposition of radar interferometry in the literature often skips such topics. This may lead to unrealistic requirements for the accuracy of determining the parameters of imaging geometry, unachievable precision of image co-registration, etc. To address these deficiencies, in the current work we analyze the problem of interferometric height reconstruction and provide a careful and detailed account of all the assumptions and requirements to the imaging geometry and data processing needed for a successful extraction of height information from the radar data. We employ two most popular scattering models for radar targets: an isolated point scatterer and delta-correlated extended scatterer, and highlight the similarities and differences between them.

Sparse regression plays a very important role in statistics, machine learning, image and signal processing. In this paper, we consider a high-dimensional linear inverse problem with \begin{document}$ \ell^0 $\end{document}-\begin{document}$ \ell^2 $\end{document} penalty to stably reconstruct the sparse signals. Based on the sufficient and necessary condition of the coordinate-wise minimizers, we design a smoothing Newton method with continuation strategy on the regularization parameter. We prove the global convergence of the proposed algorithm. Several numerical examples are provided, and the comparisons with the state-of-the-art algorithms verify the effectiveness and superiority of the proposed method.
Learning to scan: A deep reinforcement learning approach for personalized scanning in CT imaging
Authors: Shen Ziju , Wang Yufei , Wu Dufan , Yang Xu , Dong Bin
Published: July 2021

. Computed Tomography (CT) takes X-ray measurements on the subjects to reconstruct tomographic images. As X-ray is radioactive, it is desirable to control the total amount of dose of X-ray for safety concerns. Therefore, we can only select a limited number of measurement angles and assign each of them limited amount of dose. Traditional methods such as compressed sensing usually randomly select the angles and equally distribute the allowed dose on them. In most CT reconstruction models, the emphasize is on designing effective image representations, while much less emphasize is on improving the scanning strategy. The simple scanning strategy of random angle selection and equal dose distribution performs well in general, but they may not be ideal for each individual subject. It is more desirable to design a personalized scanning strategy for each subject to obtain better reconstruction result. In this paper, we propose to use Reinforcement Learning (RL) to learn a personalized scanning policy to select the angles and the dose at each chosen angle for each individual subject. We first formulate the CT scanning process as an Markov Decision Process (MDP), and then use modern deep RL methods to solve it. The learned personalized scanning strategy not only leads to better reconstruction results, but also shows strong generalization to be combined with different reconstruction algorithms.
De Compostela a Toledo: una panorámica en torno al patronazgo artístico del arzobispo Gómez Manrique (†1375)
Authors: Moráis Morán José Alberto
Published: July 2021

Esta investigación analiza el patronazgo artístico del arzobispo don Gómez Manrique, reflexionando sobre su cursus honorum y las obras que financió en las catedrales de Santiago de Compostela y Toledo y los monasterios de Nuestra Señora de Sopetrán y San Bartolomé de Lupiana. Un estudio global de una vida marcada por la instrumentalización del poder de la corona y los ambientes de crisis en los que desarrolló su actividad político-religiosa permite explicar la naturaleza de los encargos arquitectónicos y artísticos que realizó. El análisis documental, el arqueológico y el de las empresas conservadas demuestra, en las obras gallegas, el apego a una tradición artística conservadora, de carácter defensivo y rudas formas que dejó paso, años más tarde, a los escenarios artísticos renovados y de gran empaque de la diócesis toledana.
Rounded Edges: Modernism and Architectural Dialogue in Ho Chi Minh City
Authors: Hahn H. Hazel
Published: July 2021

It is widely considered that there is no critical mass of architecture in a homogeneous style in Ho Chi Minh City, in contrast to Hanoi. This essay seeks to establish Ho Chi Minh City’s architectural heritage as a significant one, by arguing that the city does actually possess a critical mass of cohesive, remarkably well-designed buildings in modernist styles. Highlighted here is a unique feature of these modernist buildings: rounded, curved corners as a recurring motif in a dense urban center. The author argues that such buildings, dating from the 1920s through the 1970s, have provided the center of Ho Chi Minh City unique, cohesive, and striking characteristics and that they form one of the great ensembles of modernist architecture anywhere. This essay aims to re-locate the place of Ho Chi Minh City on the world map of the circulation of modernism, by emphasizing the internal dynamic of the city’s architectural evolution that transcends the colonial-postcolonial divide, and highlighting the evolution of forms revealing a continuity in spite of event-based ruptures in history. The significant presence of modernist buildings with curved corners in Phnom Penh, and their similarities to those of Ho Chi Minh City, suggest that regional circulation also played a crucial role.
Constructing Heritage Through State Architecture in Indonesia’s Riau Islands
Authors: Moser Sarah , Shamsa Wilbur Alyssa
Published: July 2021

Since the implementation of decentralization policies following the fall of Suharto in 1998, Indonesia’s provinces have far greater autonomy, which they have leveraged to enhance aspects of their cultural identity. In the context of Riau Islands Province, a new province created in 2004, the pivot away from a centralized national focus has prompted policies that prioritize the revival of Malay culture in various spheres of life including education, the arts, and the built environment. This paper examines the cultural politics of recent state architectural projects created in the past fifteen years in and around the provincial capital of Tanjung Pinang, all of which are intended to evoke a sense of Malay cultural and religious identity. Recent state architecture seeks to channel and project an “authentic” past, often through a selective amalgamation of various recognizable historical references. In the context of current local political, racial, and religious dynamics, we analyze how versions of Malay identity are appropriated by the state in a variety of ways and manifested in recent state architecture in Riau Islands Province, and examine how this contributes to a variety of social exclusions.
Grossophobie
Authors: Carof Solenne
Published: July 2021

Depuis les années 1990, des associations, comme Allegro Fortissimo et plus récemment Gras politique, ainsi que des militantes et autrices comme Gabrielle Deydier, ont imposé un nouveau terme pour parler des discriminations liées au poids : la grossophobie. La tendance « body positive », résultat de ces mobilisations contre les normes esthétiques et pondérales dominantes, a renouvelé les problématiques propres aux mouvements féministes et queer, mettant à nouveau la question du corps au cœur des revendication des militantes dans le monde entier. Pourtant, les réseaux sociaux demeurent saturés d'« humour » grossophobe et la tyrannie de la minceur continue de sévir, générant mal-être, troubles du comportement alimentaire ou encore pratiques d'autocensure. Plus grave encore, les études chiffrées sur la grossophobie montrent qu’au-delà d’un certain poids les discriminations se systématisent. Elles ont lieu à l’embauche, au travail, mais aussi sur les applications de rencontre, dans les salles de sport, chez le médecin et même dans l’intimité, avec la famille. Avec cet ouvrage, Solenne Carof, signe une des premières études sociologiques sur la grossophobie en France. Que vivent les personnes très corpulentes dans une société comme la nôtre ? Que révèle le stigmate de gros ou de grosse des normes qui pèsent différemment sur les hommes et sur les femmes ? Quelles conséquences cette stigmatisation a-t-elle sur les personnes concernées ? Au fil de son enquête, l’autrice dévoile les rapports de pouvoir qui se nichent dans la question du poids et structurent les hiérarchies propres à notre société. Une étude décisive pour mettre en évidence l’importance d’une discrimination encore peu condamnée, tant socialement que juridiquement.
Timing of Immunotherapy in Type 1 Diabetes: The Earlier, the Better?
Authors: Felton Jamie L
Published: July 2021

In 1986, The New England Journal of Medicine published George Eisenbarth’s (Eisenbarth. 1986. N. Engl. J. Med. 314: 1360–1368) model of type 1 diabetes (T1D) as a chronic autoimmune disease. In 2019, the same journal published the results of the teplizumab trial, which showed the anti-CD3 mAb delayed T1D progression in high-risk individuals. Although teplizumab is the first immunomodulatory agent to demonstrate significant delay in disease progression, it is also one of the few tested prior to clinical disease onset. Is it possible, then, that this trial’s success is as much about the agent as it is about its timing? This commentary will review the landscape of immune intervention in T1D since 1986, discuss the teplizumab trial results, and finally, speculate on whether current paradigms for T1D immune intervention should focus less on disease development as a continuum and more on the stages of T1D progression as distinct disease processes.
Characterizations of right rejective chains
Authors: Tsukamoto Mayu
Published: July 2021

In this paper, we give characterizations of the category of finitely generated projective modules having a right rejective chain. By focusing on the characterizations, we give sufficient conditions for right rejective chains to be total right rejective chains. Moreover, we prove that Nakayama algebras with heredity ideals, locally hereditary algebras and algebras of global dimension at most two satisfy the sufficient conditions. As an application, we show that these algebras are right-strongly quasi-hereditary algebras.
Maximizing the ratio of eigenvalues of non-homogeneous partially hinged plates
Authors: Berchio Elvise , Falocchi Alessio
Published: July 2021

We study the spectrum of non-homogeneous partially hinged plates having structural engineering applications. A possible way to prevent instability phenomena is to maximize the ratio between the frequencies of certain oscillating modes with respect to the density function of the plate; we prove existence of optimal densities and we investigate their analytic expression. This analysis suggests where to locate reinforcing material within the plate; some numerical experiments give further information and support the theoretical results.
Radon measure-valued solutions of quasilinear parabolic equations
Authors: Tesei Alberto
Published: July 2021

We discuss some recent results concerning Radon measure-valued solutions of the Cauchy–Dirichlet problem for

\partial_t u = \Delta\phi(u)

. The function

\phi

is continuous, nondecreasing, with a growth at most powerlike. Well-posedness and regularity results are described, which depend on whether the initial data charge sets of suitable capacity (determined both by the Laplacian and by the growth order of

\phi

), and on suitable compatibility conditions at

\pm\infty

.

Interacting particle systems with long-range interactions: scaling limits and kinetic equations
Authors: Nota Alessia , Velázquez Juan J.L. , Winter Raphael
Published: July 2021

The goal of this paper is to describe the various kinetic equations which arise from scaling limits of interacting particle systems. We provide a formalism which allows us to determine the kinetic equation for a given interaction potential and scaling limit. Our focus in this paper is on particle systems with long-range interactions. The derivation here is formal, but it provides an interpretation of particle systems as the motion of a particle in a random force field with a friction term which is due to the interaction with the surrounding particles. Some of the technical details of this method are discussed in the companion paper [50].
Effects of Ethanolic Extract of Kiam Wood/Cashew Bark and Commercial Phenolic Compounds Oxidized Under Alkaline Condition on Gel Property of Gelatin from Cuttlefish Skin
Authors: Temdee Wattan , Benjakul Soottawat , Surasani Vijay Kumar Reddy , Singh Avtar
Published: July 2021

The effect of ethanolic extracts of kiam wood (EKW) or cashew bark (ECB) and commercial phenolic compounds oxidized under alkaline condition (pH 9) on gel properties of gelatin extracted from cuttlefish skin was investigated. All the oxidized compounds increased gel strength (GS) of gelatin, in which the highest value was noticed for gels containing oxidized catechin (CH-G) and gallic acid (GA-G) (P<0.05). Among the ethanolic extracts, the gel added with EKW (EKW-G) had higher GS than that containing ECB gel (ECB-G) (P<0.05). Both extracts yielded gels with similar GS to those added with oxidized ferulic and tannic acids (P>0.05). Lightness and free amino group content of gels were decreased with the addition of oxidized compounds, regardless of their types. Gels added with oxidized compounds showed lower solubility and amino group content as compared to the control, indicating the formation of nondisulphide covalent bonds in the gel matrix. The treated samples showed a gel network with thicker strands and larger voids, compared with the control gel. Overall, oxidized EKW extract had a similar impact on the gel properties of gelatin to the oxidized phenolic compounds, especially catechin and gallic acids.
Boulezova racionalna serialna organizacija in Cageovo naključje – enakost različnega
Authors: Pompe Gregor
Published: July 2021

Konec druge svetovne vojne je mogoče razumeti tudi kot pomembno estetsko ločnico v zgodovini novejše svetovne glasbe. Nestabilna duhovna klima, ki je bila prežeta z groznimi spomini na pravkar končano vojno in strahom pred nejasno prihodnostjo, ter dolgoletni izolacija in diskontinuiteta glasbenega življenja so omogočili in narekovali generaciji mladih skladateljev, da do temlja spremenijo tradicionalni glasbeni »jezik«. Pri tem so sicer izhajali iz Schönbergove dvanajsttonske tehnike, vendar pa so osnovno idejo – ureditev vseh dvanajstih poltonov oktave v vrsto – prenesli še na druge parametre zvoka (ritmične dolžine, dinamika, artikulacija). Tako je Pierre Boulez leta 1951 s skladbo Structures Ia za dva klavirja udejanil zamisel o homogeni serialni strukturi, v kateri so vrste za posamezne parametre zvoka urejene tabelarno, njihovo distribucijo pa kontrolirajo »nadvrste«, izpeljane iz osnovnih vrst. Istega leta je tabelarno uredil glasbeni material za svojo skladbo Music of Changes tudi John Cage, ki je prek korespondence Boulezu sploh prvi nakazal možnost tabelarnega urejanja materiala za vse parametre zvoka. Vendar pa Cage ni izbral nadvrst in se je namesto racionalni sistematiki pri distribuciji izbranega materiala z metom kovancev že prepustil naključju. Tako sta paradoksalno prav skladbi, v katerih sta si skladatelja za izhodišče izbrala zelo podoben koncept, pripeljali do popolne ločitve, po kateri Bouleza in Cagea povezujemo z dvema navidez diametralno nasprotnima tokovoma v glasbi po drugi svetovni vojni: serialnostjo in aleatoriko. Vendar pa nam analizi zvočnih rezultatov obeh skladb dajeta zelo podobne rezultate, kar postavlja prizadevanja obeh skladateljev iz začetka petdesetih let 20. stoletja v povsem novo luč in jima daje posebno dokumentarno vrednost. V obeh primerih lahko namreč slišimo vrsto med seboj nepovezanih tonov, razpršenih v širokem ambitusu, brez razločnega metričnega impulza, v konstantnem, kontrastnem menjavanju dinamike. Zato analiza ne more več iskati melodije, harmonije, urejenega ritmično-metričnega pulza, motivično-tematskega dela ali klasične formalne gradnje; glasbeni stavek je veliko bolj odvisen od fizikalnih parametrov zvoka in njihovega spreminjanja (gostota teksture, povprečna jakost in frekvenca zvoka, število dogodkov na časovno enoto). Tako obe skladbi pričata o posebnem stanju glasbenega materiala in kompozicijske tehnike po drugi svetovni vojni in o skupni želji po vzpostavitvi povsem novega glasbenega »jezika«.

Slovenska glasba med evropskim in izvirnim
Authors: Klemenčič Ivan
Published: July 2021

Ker se je slovenska glasba v vseh obdobjih od srednjega veka do danes razvijala vzporedno z zahodnoevropsko, se postavlja vprašanje historičnega razmerja: kaj je od te glasbe sprejemala in kaj ji je po svojih močeh, s svojimi predstavniki in ustanovami, prispevala. Namen besedila je predstaviti slovensko glasbo v njeni zgodovinski nacionalni (in s tem tudi prednacionalni) vlogi in jo obenem identificirati v vlogi izvirnega preseganja  na evropsko.
Reflections on the History of Computer-Assisted Music Analysis I: Predecessors and the Beginnings
Authors: Schüler Nico
Published: July 2021

This article is the first of a series that focuses on the history of computer-assisted music analysis. This first article discusses the philosophical basis of computer-assisted music analysis, i.e. the application of information theory to aesthetics, as well as representative applications of statistical and information-theoretical measurements to music analysis and other computational approaches to music analysis that did not include the use of electronic computers. In most cases, those approaches were direct models for computer-assisted applications. Finally, this article provides a short historical account of the development of early computers and summarizes the earliest computer-applications to music analysis, carried out during the 1950s.
