CYBERSPACE DAN POPULISME ISLAM DI KALANGAN NETIZEN: STUDI KASUS PADA AKUN MEDIA SOSIAL FELIX SIAUW
Authors: Hannan Abd
Published: April 2021

The massive use of social media has led to the increasing phenomenon of Islamic populism among netizens. This phenomenon is marked by the presence of contemporary religious actors. One of them is Felix Siauw. This paper aims to analyze the phenomenon of cyberspace and Islamic populism among netizens, especially on Felix Siauw's Instagram (IG) account. This study used a qualitative approach in the form of netnography, through tracing the IG Felix Siaw account. The collected data then being analyzed using Jurgen Habermas's theory of public space. The results reveal that the role and influence of the presence of contemporary religious actors, such as Felix Siauw, can be illustrated in three ways: first, the use of anti-establishment narratives; second, the use of anti-authoritarianism narratives; third, the invitation to return to the basic values of Islam (Al-Qur'an and Hadith) as a guidance for a whole life of a muslim, including his or her life as a citizen. To maximize his populist agenda, IG Felix Siauw's account uses populist themes that are close to the daily lives of netizens, such as the Indonesian without Dating Movement, Youth Hijrah, Indonesia Bertauhid, and the Khaffah Islamic Movement.Masifnya penggunaan sosial media memunculkan fenomena populisme Islam di kalangan netizen. Fenomena ini ditandai oleh kehadiran aktor-aktor agama kekinian, salah satunya adalah Felix Siauw. Tulisan ini bertujuan menganalisis fenomena cyberspace dan populisme Islam di kalangan netizen, khususnya pada akun Instagram (IG) Felix Siauw. Penelitian ini menggunakan pendekatan kualitatif berupa netnografi, melalui penelusuran akun IG Felix Siaw. Data kemudian dianalisis menggunakan teori Ruang Publik Jurgen Habermas. Hasil penelitian mengungkapkan bahwa peran dan pengaruh kehadiran aktor agama kekinian seperti Felix Siauw di kalangan netizen muslim tergambar dalam tiga hal, yaitu: pertama, penggunaan narasi antikemapanan; kedua, penggunaan narasi anti-oritarianisme; ketiga, ajakan kembali ke nilai-nilai dasar agama (Al-Qur'an dan Hadist) sebagai pegangan hidup secara menyeluruh, bahkan dalam berbangsa dan bernegara sekalipun. Untuk memaksimalkan agenda populismenya tersebut, akun IG Felix Siauw mempergunakan tema-tema populis yang dikenal dekat dengan kehidupan netizen sehari-hari, seperti Gerakan Indonesia Tanpa Pacaran, Pemuda Hijrah, Indonesia Bertauhid, Gerakan Islam Khaffah dan lain sebagainya.

REDUKSI NALAR KEAGAMAAN PARA JIHADIS
Authors: Malik 'Atiyah Rauzanah
Published: April 2021

Maraknya kekerasan yang mengatasnamakan agama kian terjadi bahkan di era digital seperti saat ini. Kekerasan itu terjadi tak hanya kepada kelompok-kelompok yang dianggap sebagai non-muslim, namun juga di internal muslim sendiri. Melalui berbagai aksi kekerasan seperti penggerebekan hingga yang paling ekstrem seperti bom bunuh diri, para pelaku yang acap kali dijuluki jihadis ini merasa absah melakukan kekerasan karena dilandasi oleh keyakinan bahwa apa yang mereka lakukan merupakan sebuah bentuk jihad fii sabilillah. Lantas, apa yang sebenarnya melatarbelakangi pemikiran para jihadis ini sehingga mereka merasa terlegitimasi melakukan berbagai tindakan kekerasan dengan mengatasnamakan agama dan Tuhan. Apakah karena dasar normatif (al-Qur’an dan Hadits) yang telah tereduksi dan menjadi basis pijakan pikiran dan tindakan mereka, atau justru dasar pemikiran beragama mereka yang menjadi sebab legalitas rangkaian tindakan kekerasan itu? Buku yang ditulis oleh Aksin Wijaya ini begitu menarik karena mengulas genealogi bentuk-bentuk tindakan kekerasan oleh mereka yang kita sebut dengan kaum jihadis ini dengan membedah sisi nalar keagamaan. Nalar yang diulas di sini tidak hanya tentang cara mereka berpikir (menalar Islam) saja melainkan juga tentang nalar keislaman yang mengideologi dalam setiap pribadi para jihadis.

Published: April 2021

Rubber tree cultivation is limited in many regions by abiotic factors such as drought. We investigated the biochemical mechanisms responsible for responses to, and recovery from, drought conditions during the establishment phase of four high latex producing rubber tree clones (RRIM600, IAC40, PR255 and GT1). Five-month-old plants were exposed to 32 days of water restriction, followed by 15 days of soil rehydration. Leaf area, as well as their osmolyte accumulations, saccharolytic enzyme activity, and oxidative stress markers, were accompanied. Although clones IAC40 and PR255 responded more precociously to drought conditions, halting leaf expansion before clones GT1 and RRIM600, they demonstrated slow recuperation after reestablishing irrigation. The greater tolerances of clones RRIM600 and GT1 to drought conditions were related to greater vacuolar invertase (VINV) activity in their leaves, which guaranteed more significant accumulations of vacuolar reducing sugars (RS). Similar to RS, glycine betaine accumulations were related to osmoprotection and to reducing oxidative damage (lipidic peroxidation) caused by water deficit conditions. The observed decreases in cytosol neutral invertase (AINV) and cell wall insoluble invertase (CWINV) activities, which resulted in cytosol hexose decreases, may be related to increases in antioxidant enzyme (superoxide dismutase and ascorbate peroxidase) activities in the leaves in response to water deficit conditions. As such, the introduction of specific sugars (RS) and the modulation of key carbon metabolism enzymes, such as VINV, are promising strategies for promoting drought tolerance in rubber tree clones.

Adansonia digitata L. is a tree indigenous to Ghana and West Africa. It is traditionally used for medicinal, religious and nutritional purposes. Different parts of the plant are used traditionally for the treatment of diseases such as anaemia, malaria, asthma and diarrhoea among others. It is therefore necessary to provide standard parameters for identification and for the purpose of quality control. This study thus sought to investigate the pharmacognostic characteristics and elemental properties of the leaves and stem bark of A. digitata grown and used in Ghana. The macroscopic and microscopic characteristics, phytochemical, physicochemical, fluorescence and elemental properties of the leaf and stem bark were determined using standard protocols. The results of the study showed that the leaves of A. digitata were palmate compound and alternately arranged with stipules at each node. The outer bark was observed to be grey in color while the inner bark was pink to brown and laticiferous. Anomocytic stomata and stellate trichomes were also observed microscopically on the leaf surface. The powdered stem bark contained brachysclereids and prismatic calcium oxalate crystals. Saponins, tannins, flavonoids and alkaloids were detected in both leaf and stem bark. They additionally exhibited different fluorescence characters in various solvents. The plant contained major and minor nutritional elements in varying quantities. The results of this study can serve as reliable parameters for accurate identification and authentication of A. digitata L. hence ensuring quality.
Heavy metal stress influence the andrographolide content, phytochemicals and antioxidant activity of Andrographis paniculata
Authors: Antony Anna , Nagella Praveen
Published: April 2021

Heavy metals (HM) are toxic components present in the earth’s crust that can have a negative impact on plants as well as animals. Andrographis paniculata or ‘King of bitters’ belonging to the family Acanthaceae, is a medicinal herb traditionally used in the treatment of fever, common cold etc. In the present study, the effect of heavy metals (copper, tin and cobalt) on the andrographolide content, biochemical parameters like chlorophyll, carotenoid, protein, Total phenolic content (TPC), Total flavonoid content (TFC) and antioxidant activity in A. paniculata were analysed. Saplings of A. paniculata were treated at 50 and 100 mM concentrations, three different times at a time interval of 7 days. Andrographolide production was found to increase in copper and cobalt treated saplings when compared with the control. From the results, maximum andrographolide concentration was found in the saplings treated with 50 mM copper (8.51 mg/g of DW) and 50 mM tin (8.10 mg/g of DW) respectively. 50 mM cobalt treated plants have shown the highest concentration of TPC (17.21 mg/g of extract) and TFC (6.97 mg/g of extract). Notable variations in other biochemical parameters like total chlorophyll, carotenoid content and antioxidant activities were observed in all treatments compared with the control.

Published: April 2021

The mission for drug discovery and progress has prompt researchers to scientifically validate the therapeutic uses of medicinal plants available worldwide, of which, African medicinal plants serve as a great reservoir. Despite the extensive work in the field of medicinal plants of African origin, however, bibliometric report on the work conducted on African medicinal plants is scarce, and hence, the present study aimed at evaluating the top 100 most cited articles on medicinal plant wealth of Africa. The literature data used for the bibliometric analysis was explored from Web of Science (WoS) while RStudio and VOSviewer software were used for data analysis and collaboration network visualization, respectively. The most prolific authors were Van Staden J, Jager AK, Teklehaymanot T whereas, the top 3 journals were Journal of Ethnopharmacology, Journal of Ethnobiology and Ethnomedicine, and South African Journal of Botany. Most cited journals were Journal of Ethnopharmacology, Phytochemistry, Phytotherapy Research. The topmost institutions in terms of the number of articles were the University of KwaZulu-Natal, University of Addis Ababa and Pretoria. South Africa was the most cited country followed by Nigeria. Single country publications dominated the field and therefore, multiple country collaboration should be a focus of social networks among the researchers in the field.

Published: April 2021

Shrub Lycium barbarum belongs of the family Solanaceae, is introduced and does not occur naturally in Uzbekistan. Despite its numerous medicinal characteristics, in Uzbekistan, its growth and development have not been studied. Therefore, our primary goal was to study the germination of seeds, stages of ontogenesis and some morphological signs of fruits. The highest seed germination rate of 74±0,12% as at the 20 degree C. When studying ontogenesis, plant development was divided into ten stages and four periods. The pre-reproductive period lasted 1-2 years. The reproductive period was determined for 2-3 years from the beginning of the growing season. For several months, an analysis of the changes in the morphological characteristics of the fruits of L. barbarum was carried out and in May, relatively large ripened fruits were determined (length 2.18 ± 0.09, width 1.14 ± 0.11).

Published: April 2021

Barley is cultivated mainly for feed purposes in the Tyumen region. At the same time, there is a need to obtain brewing barley grain. This research is aimed at establishing the influence of elements of cultivation technology on the productivity of barley varieties and identifying the compliance of grain quality indicators with the established requirements. The studies were performed in three field experiments on the experimental field of the of the Northern Trans-Ural State Agricultural University in the northern forest-steppe of the Tyumen region in 2014 - 2016. In terms of the complex indicator – the collection of protein from a unit area – the Lamador Pro + Rostok variant stood out: for the Acha variety, this indicator was 612 kg/ha, for the Abalak variety - 646 kg/ha. The best indicators were obtained in the variant with the use of Hydromix complex for treating the seeds: for the Acha variety, the yield was 4.55 t/ha, for the Abalak variety - 4.62 t/ha, the protein content in the grain was 13.1 and 13.3%, respectively. In terms of yield, Omsky 85, Payjazz and Beatrice varieties surpassed the standard. The obtained research results are recommended for implementation at the enterprises of the agro-industrial complex of the Tyumen region.
Impacts of Jobs Requiring Close Physical Proximity and High Interaction with the Public on U.S. Industry Employment Change During the Early Stages of the COVID-19 Pandemic
Authors: Gabe Todd , Florida Richard
Published: April 2021

This paper examines the factors affecting U.S. industry employment change in the early months of the COVID-19 pandemic. Results show that the percentage of industry employment in occupations that require close physical proximity has a negative effect on year-over-year employment change in the six months of April through September of 2020. On the other hand, the percentage of industry employment in jobs that involve high interaction with the public has a negative effect on year-over-year employment change in April and May, but not in the months of June to September. These different results related to physical proximity and interaction with the public are driven, in part, by the uneven impacts of COVID-19 on hospitality and retail businesses.

Objectives

Delays in sepsis diagnosis can increase morbidity and mortality. Previously, we performed a Symptom-Disease Pair Analysis of Diagnostic Error (SPADE) “look-back” analysis to identify symptoms at risk for delayed sepsis diagnosis. We found treat-and-release emergency department (ED) encounters for fluid and electrolyte disorders (FED) and altered mental status (AMS) were associated with downstream sepsis hospitalizations. In this “look-forward” analysis, we measure the potential misdiagnosis-related harm rate for sepsis among patients with these symptoms.

Methods

Retrospective cohort study using electronic health record and claims data from Kaiser Permanente Mid-Atlantic States (2013–2018). Patients ≥18 years with ≥1 treat-and-release ED encounter for FED or AMS were included. Observed greater than expected sepsis hospitalizations within 30 days of ED treat-and-release encounters were considered potential misdiagnosis-related harms. Temporal analyses were employed to differentiate case and comparison (superficial injury/contusion ED encounters) cohorts.

Results

There were 4,549 treat-and-release ED encounters for FED or AMS, 26 associated with a sepsis hospitalization in the next 30 days. The observed (0.57%) minus expected (0.13%) harm rate was 0.44% (absolute) and 4.5-fold increased over expected (relative). There was a spike in sepsis hospitalizations in the week following FED/AMS ED visits. There were fewer sepsis hospitalizations and no spike in admissions in the week following superficial injury/contusion ED visits. Potentially misdiagnosed patients were older and more medically complex.

Conclusions

Potential misdiagnosis-related harms from sepsis are infrequent but measurable using SPADE. This look-forward analysis validated our previous look-back study, demonstrating the SPADE approach can be used to study infectious disease syndromes.

Published: April 2021

Wood as a construction material affects indoor environmental quality by moisture buffering, good acoustic properties and by the wood specific volatile organic compounds (VOC). The most abundant VOCs of soft wood are volatile monoterpenes (VM) giving the typical odor of wood. In the present study, long-term VM emissions of wood of two northern coniferous tree species, Scots pine and Norway spruce were observed regularly during one year in storage. Fresh and dried 20 cm long wood blocks were placed in a test chamber; VMs were collected with the solid phase micro extraction fiber and analyzed by gas chromatography-mass spectrometer. Average emission of nine different VMs, α- and β-pinene, 3-carene, limonene, terpinolene, myrcene, camphene, ortho-cymene and ƴ-terpinene, decreased 68–87% during one-year long storage. Moisture content (MC), knots, tree species and tree individual affected the VM emissions from wood. When a certain level of MC (12%) was reached, the VM levels decreased, but the method of drying (industrial or dried in storage) did not affect the amount of released VMs. Rehydration and dehydration increased and decreased VM emissions, respectively. Moreover, two of the eight Scots pine heartwood planks contained almost no 3-carene while being the most abundant monoterpene in the others.
IL-24 inhibits the malignancy of human glioblastoma cells via destabilization of Zeb1
Authors: Lin Tie , Wang Dongpeng , Chen Jun , Zhang Zhan , Zhao Yuming , Wu Zhong , Wang Yuehua
Published: April 2021

Glioblastoma (GBM) is the most common and fatal type of primary malignant tumours in the central nervous system. Cytokines such as interleukins (ILs) play an important role in GBM progression. Our present study found that IL-24 is down-regulated in GBM cells. Recombinant IL-24 (rIL-24) can suppress the in vitro migration and invasion of GBM cells while increase its chemo-sensitivity to temozolomide (TMZ) treatment. rIL-24 negatively regulates the expression of Zeb1, one well known transcription factors of epithelial to mesenchymal transition (EMT) of cancer cells. Over expression of Zeb1 can attenuate IL-24-suppressed malignancy of GBM cells. Mechanistically, IL-24 decreases the protein stability of Zeb1 while has no effect on its mRNA stability. It is due to that IL-24 can increase the expression of FBXO45, which can destabilize Zeb1 in cancer cells. Collectively, we reveal that IL-24 can suppress the malignancy of GBM cells via decreasing the expression of Zeb1. It suggests that targeted activation of IL-24 signals might be a potential therapy approach for GBM treatment.
Optimal placement of distributed generation based on DISCO’s additional benefit using self adaptive levy flight based black widow optimization
Authors: Gubbala Venkata Naga Lakshmi , Askani Jaya Laxmi , Veeramsetty Venkataramana
Published: April 2021

Optimal placement of Distributed Generation (DG) is a crucial challenge for Distribution Companies (DISCO’s) to run the distribution network in good operating conditions. Optimal positioning of DG units is an optimization issue where maximization of DISCO’s additional benefit due to the installation of DG units in the network is considered to be an objective function. In this article, the self adaptive levy flight based black widow optimization algorithm is used as an optimization strategy to find the optimum position and size of the DG units. The proposed algorithm is implemented in the IEEE 15 and PG & E 69 bus management systems in the MATLAB environment. Based on the simulation performance, it has been found that with the correct location and size of the DG modules, the distribution network can be run with maximum DISCO’s additional benefit.
An efficient class of fourth-order derivative-free method for multiple-roots
Authors: Kumar Sunil , Kumar Deepak , Sharma Janak Raj , Argyros Ioannis K.
Published: April 2021

Many optimal order multiple root techniques, which use derivatives in the algorithm, have been proposed in literature. Many researchers tried to construct an optimal family of derivative-free methods for multiple roots, but they did not get success in this direction. With this as a motivation factor, here, we present a new optimal class of derivative-free methods for obtaining multiple roots of nonlinear functions. This procedure involves Traub–Steffensen iteration in the first step and Traub–Steffensen-like iteration in the second step. Efficacy is checked on a good number of relevant numerical problems that verifies the efficient convergent nature of the new methods. Moreover, we find that the new derivative-free methods are just as competent as the other existing robust methods that use derivatives.

Edgar Wind on Experiment and Metaphysics
Authors: Falkenburg Brigitte
Published: April 2021

The paper presents a detailed interpretation of Edgar Wind’sExperiment and Metaphysics(1934), a unique work on the philosophy of physics which broke with the Neo-Kantian tradition under the influence of American pragmatism. Taking up Cassirer’s interpretation of physics, Wind develops a holistic theory of the experiment and a constructivist account of empirical facts. Based on the concept of embodiment which plays a key role in Wind’s later writings on art history, he argues, however, that the outcomes of measurements are contingent. He then proposes an anti-Kantian conception of a metaphysics of nature. For him, nature is an unknown totality which manifests itself in discrepancies between theories and experiment, and hence the theory formation of physics can increasingly approximate the structure of nature. It is shown that this view is ambiguous between a transcendental, metaphysical realism in Kant’s sense and an internal realism in Putnam’s sense. Wind’s central claim is that twentieth century physics offers new options for resolving Kant’s cosmological antinomies. In particular, he connected quantum indeterminism with the possibility of human freedom, a connection that Cassirer sharply opposed.

Published: April 2021

Objective: This study aims to figure out risk factors of in-hospital preoperative rupture of hyperacute type A aortic dissection (haTAAD) patients and build a prediction and risk stratification model.
Methods: From January 2011 to December 2019, 830 patients diagnosed as haTAAD from Nanjing Drum Tower Hospital were enrolled. Among them, 799 patients received prompt surgery and 31 suffered aortic rupture before operation. The association between in-hospital preoperative rupture and perioperative parameters were examined. Best subset selection was used for feature selection and ROC curve was used to identify the model.
Results: Age, winter season, back pain, preoperative hypotension, albumin and globulin ratio, high serum phosphorus level are risk factors for in-hospital preoperative rupture of haTAAD. On the basis of six variables with AUC 0.828, a nomogram was established. According to the robustness test, actual in-hospital preoperative ruptures were fitted well.
Conclusions: The in-hospital rupture prediction model was developed using logistic regression analysis. High serum phosphorus level is one of the strongest predictors. This nomogram may be useful when evaluating the risk of aortic dissection in-hospital rupture in future trials.

Novel Non-invasive Fractional Flow Reserve from Coronary CT Angiography to Determine Ischemic Coronary Stenosis
Authors: Cherukuri Lavanya , Birudaraju Divya , Budoff Matthew J
Published: April 2021

Coronary artery disease (CAD) patients may have an obstructive disease on invasive coronary angiography, but few of these patients have had flow-limiting obstructive disease diagnosed on invasive fractional flow reserve (FFR). FFR is infrequently performed because of its cost- and time-effectiveness. Advancement in non-invasive imaging has enabled FFR to be derived non-invasively using coronary CT angiography (CCTA), without the need for induction of hyperemia or modification of the standard CCTA acquisition protocol. FFR derived from CCTA (FFRCT) has been shown to have excellent correlation with invasive FFR, and remains an effective diagnostic tool in the presence of reduced signal-to-noise ratio, coronary calcification and motion artifact. The utility of FFRCT has also helped to deepen our understanding of hemodynamically significant CAD. Hence, there is now interest in exploring the possible interplay between these mechanistic forces and their effect on the development of coronary plaque and the vulnerability of these plaques.
Optimizing Guideline-directed Medical Therapies for Heart Failure with Reduced Ejection Fraction During Hospitalization
Authors: Dixit Neal M , Shah Shivani , Ziaeian Boback , Fonarow Gregg C , Hsu Jeffrey J
Published: April 2021

Heart failure remains a huge societal concern despite medical advancement, with an annual direct cost of over $30 billion. While guideline-directed medical therapy (GDMT) is proven to reduce morbidity and mortality, many eligible patients with heart failure with reduced ejection fraction (HFrEF) are not receiving one or more of the recommended medications, often due to suboptimal initiation and titration in the outpatient setting. Hospitalization serves as a key point to initiate and titrate GDMT. Four evidence-based therapies have clinical benefit within 30 days of initiation and form a crucial foundation for HFrEF therapy: renin-angiotensin-aldosterone system inhibitors with or without a neprilysin inhibitor, β-blockers, mineralocorticoid-receptor-antagonists, and sodium-glucose cotransporter-2 inhibitors. The authors present a practical guide for the implementation of these four pillars of GDMT during a hospitalization for acute heart failure.

The purpose of this study was to investigate the web pedagogical content knowledge of science teachers. As a mixed method design, this study was carried out with science teachers. A total of 229 science teachers participated in the quantitative part of the study and 17 science teachers with different year experience took part in the qualitative part. Quantitative data in the study were collected through the Web Pedagogical Content Knowledge Scale and the qualitative data were collected by a semi-structured interview. The obtained quantitative data were analyzed using descriptive statistics, Mann-Whitney U test and Kruskal-Wallis H test. The content analysis was used on the qualitative data. The quantitative results of the research indicated that the levels of teachers’ self-efficacy perceptions regarding web pedagogical content knowledge were very high. Moreover, the scores obtained from the overall scale and its sub-dimensions significantly differed with regards to work experience of science teachers. The qualitative findings of the study revealed that science teachers made use of the Web for lectures, experiments, practice, visual support, videos, and compensating the lack of materials. It was also emphasized that teachers should be educated to use the Web in their teaching practices.Key words: science teachers; web-based teaching; web pedagogical content knowledge; self-efficacy. --- Cilj ovoga istraživanja bio je ispitati poznavanje mrežnoga pedagoškog sadržaja nastavnika prirodnih predmeta.

The paper defines a special type of problem tasks and considers its didactic potential, as well as the success of students in solving the selected problem. The research instrument used is a geometrical task from the National Secondary School Leaving Exam in Croatia (State Matura). The geometrical task is presented in three versions: as a verbal problem, as a verbal problem with a corresponding image and as a problem in context. The material analysed in the present paper was collected from 182 students in 7th and 8th grade of Croatian urban elementary schools. The didactic potential is considered from the aspect of use of mathematical concepts and connections. The success of students in problem-solving is considered from the aspect of implementation of the problem-solving process and producing correct answers, depending on the manner in which the tasks are set up. The results show that the stand-alone problem, as a special type of problem task, has considerable didactic potential. However, the students’ skills of discovering and connecting mathematical concepts and their properties are underdeveloped. In addition, the manner in which the tasks are set up considerably affects the process of solving the task and consequently the success of that process. Based on the results of the research, proposals are given for application of stand-alone problems in teaching mathematics.Key words: isolated problem; mathematical task; problem solving; problem evaluation.  --- U radu se definira posebna vrsta problemskoga zadatka te se razmatra njegov didaktički potencijal kao i uspješnost učenika u rješavanju odabranoga problema. Instrument istraživanja je geometrijski zadatak s državne mature koji se postavlja u tri inačice: kao tekstualni problem, kao tekstualni problem uz odgovarajuću sliku te kao zadatak u kontekstu. U istraživanju je sudjelovalo 182 učenika 7. i 8. razreda hrvatskih gradskih osnovnih škola. Didaktički potencijal razmatra se s aspekta iskoristivosti matematičkih koncepata i veza, a uspješnost učenika u rješavanju problema razmatra se s aspekta provedbe procesa rješavanja i otkrivanja točnoga rješenja ovisno o načinu postavljanja zadatka. Rezultati pokazuju da promatrani problem kao posebna vrsta problemskoga zadatka ima veliki didaktički potencijal, ali da učenici imaju nedovoljno razvijene vještine otkrivanja i povezivanja matematičkih koncepata i njihovih svojstava. Osim toga, način postavljanja zadatka značajno utječe na proces rješavanja, a posljedično i na uspješnost određivanja rješenja. Na temelju rezultata daju se prijedlozi primjene opisane vrste problema u nastavi Matematike.Ključne riječi: izolirani problem; matematički zadatak; rješavanje problema; vrednovanje problema
Music Therapy in Educating Children with Developmental Disabilities / Muzikoterapija u procesu obrazovanja djece s teškoćama u razvoju
Authors: Katušić Ana , Burić Ksenija
Published: April 2021

Music therapy acts as a separate discipline in the interdisciplinary field of science and art. Unlike music education, music therapy is aimed at developing and enhancing non-musical skills by using music as a symbol of emotional and personal growth. The purpose of this paper is to present an overview of the theoretical foundations of music therapy in the field of human psychology and music pedagogy, as well as the development of music therapy models that have arisen from these theoretical approaches. The most commonly used music therapy models in special education are based on improvisational music therapy techniques, which include free improvisation therapy, creative music therapy known as the Nordoff-Robbins model, and Orff music therapy. Improvisation in these models plays a key role during the acquisition and promotion of skills. Using sounds, playing instruments, making music here and now, allows for expression and exploration, and enables children to acquire skills in different developmental domains. Finally, the paper offers an overview of the use of music therapy in education of children with developmental disabilities educating developmentally disabled children, its unique features and connections with the education through music approach, in accordance with the set-up goals of the Individual Education Plan.Key words: Individual Education Plan; music therapy; improvisational models; education; children with developmental disabilities. --- Muzikoterapija djeluje kao zasebna disciplina u interdisiciplinarnom području znanosti i umjetnosti. Za razliku od glazbenoga obrazovanja, muzikoterapija je usmjerena prema razvoju i jačanju neglazbenih vještina koristeći glazbu kao simbol emocionalnoga i osobnoga rasta. Svrha je ovoga rada prikazati pregled teorijskih osnova muzikoterapije na području humanističke psihologije i glazbene pedagogije, kao i razvoj modela muzikoterapije koji su proizašli iz navedenih teorijskih pravaca. Modeli muzikoterapije koji se najčešće koriste u procesu obrazovanja djece s teškoćama u razvoju zasnivaju se na improvizacijskim tehnikama muzikoterapije, a obuhvaćaju: terapiju slobodnom improvizacijom, kreativnu muzikoterapiju poznata kao Nordoff-Robbins model i Orff muzikoterapiju. Improvizacija u ovim modelima ima ključnu ulogu tijekom usvajanja i poticanja vještina. Korištenje  zvukova, sviranje instrumenata, stvaranje glazbe ovdje i sada, omogućava izražavanje i istraživanje, a djeci pruža mogućnost samoostvarenja na različitim razvojnim područjima. Naposljetku u radu se nudi prikaz primjene muzikoterapije u obrazovanju djece s teškoćama u razvoju, njegove jedinstvenosti te poveznice u odnosu na pristup obrazovanja kroz glazbu sukladno postavljenim ciljevima Individualnog edukacijskog plana.Ključne riječi: Individualni edukacijski plan; muzikoterapija; improvizacijski modeli; obrazovanje; djeca s teškoćama u razvoju

The objective of this study was to investigate the plasma concentrations of insulin-like growth factor-2 (IGF-2) as well as its expression in the uterus and ovary of healthy dogs and those with cystic endometrial hyperplasia (CEH)–pyometra complex. Group 1 (n = 10) included bitches with open cervix pyometra, while Group 2 (n = 7) consisted of clinically healthy bitches in dioestrus. The number of IGF-2 immunopositive interstitial cells was significantly higher in Group 1, whereas in Group 2 there were only two cases in which a few cells were IGF-2 immunopositive. IGF-2 immunopositivity was observed in the endometrial glandular epithelium in both groups. Additionally, interstitial fibroblasts and macrophages in the endometrium were also positive in Group 1. The concentration of plasma IGF-2 was higher in Group 1 than in Group 2 (P < 0.05). The concentration was positively correlated with IGF-2 expression in the endometrial glands (r = 0.926; P < 0.001) in Group 1. However, a negative correlation was present between plasma IGF-2 concentration and IGF-2 expression in the interstitial endocrine cells of the ovary in Group 1 (r = −0.652; P < 0.05). The results suggest that IGF-2 plays an important role during the inflammatory process occurring in bitches with CEH–pyometra complex as well as in the endometrium of healthy bitches in dioestrus.
Implementation of Mediation and Hakam in Divorce Case in Religious Court
Authors: Salman Salman
Published: April 2021

The resolution of divorce cases in the Religious Courts is still more dominant in the orientation of the litigation process than the non-litigation process, even though the spirit of suppressing the increase in the divorce rate from year to year is one of the missions that the Religious Courts want to achieve. Mediation institutions are actually established to encourage the realization of these ideals, but the results are still far from adequate. In fact, there are other ways in Islamic law that are believed to be effective in reducing the divorce rate, namely hakam. Unfortunately the rights have not been maximally applied by judges in resolving divorce cases at the Religious Courts

Published: April 2021

Introduction and objectives: To determine the quality of life (QoL) in Caucasian children with atopic dermatitis (AD) and their families and possible factors that might impact their QoL.
Materials and methods: In this cross-sectional study, 83 children aged 2–7 with AD and their families were enrolled as the study group, and 83 age-matched healthy children were included as controls. All patients in the AD and control groups were sorted into two age-based groups: (1) 2–4 and (2) 5–7 years of age. The parents of all children completed the Turkish version of the Pediatric Quality of Life Inventory (PedsQL).The Family Impact Scale for Dermatological Diseases (FIS-DD) was administered to the study group. Disease severity was evaluated with the Patient-Oriented Scoring Atopic Dermatitis (PO-SCORAD) scale.
Results: In both age groups, a negative correlation between the PedsQL and the FIS-DD scores (p < 0.001) was found. A positive correlation was found between the PO-SCORAD and FIS- DD scores among the second age group (p = 0.011). In the first age group, AD patients with comorbid allergic diseases had higher FIS-DD scores than those without any other allergic problems (p = 0.007).
Conclusions: We suggest that considering family QoL may positively contribute to the treatment of pre-school age AD children.

Published: April 2021

Background: Asthma control is the goal of asthma management. A nationwide study on this aspect was launched by the Italian Society of Paediatric Allergy and Immunology (ControL’Asma study). Objective: To define variables associated with different asthma control grades in a nationwide population of asthmatic children and adolescents.
Methods: This cross-sectional real-world study included 480 asthmatic children and adolescents (333 males, median age 11.2 years) consecutively enrolled in 10 third level pediatric allergy clinics. According to the Global Initiative for Asthma (GINA) document, history, medication use, perception of asthma symptoms assessed by visual analog scale (VAS), clinical examination, lung function, childhood asthma control test (cACT)/asthma control test (ACT), and asthma control level were evaluated.
Results: Considering GINA criteria, asthma was well controlled in 55% of patients, partly controlled in 32.4%, and uncontrolled in 12.6%. Regarding cACT/ACT, asthma was uncontrolled in 23.2%. Patients with uncontrolled asthma had the lowest lung function parameters and VAS scores, more frequent bronchial obstruction and reversibility, and used more oral and inhaled corticosteroids (CS).
Conclusions: The ControL’Asma study, performed in a real-world setting, showed that asthma in Italian children and adolescents was usually more frequent in males. Asthmatic patients had an early onset and allergic phenotype with very frequent rhinitis comorbidity. Uncontrolled and partly controlled asthma affected about half of the subjects, and the assessment of asthma symptom perception by VAS could be a reliable tool in asthma management.
