Published: March 2023

Бүх амьд организмын амьдран тогтнох үндэс эсийн хуваагдал, түүний нарийн зохицуулга байдаг. Эсийн хуваагдлын бүхий л хугацааны туршид циклин-CDK хос уургууд бусад уургуудын хооронд харилцан үйлчлэлд орж, уургуудийн концентрацийн өөрчлөлтөөр эсийн хуваагдах үйл явц өрнөдөг. Зохицуулга алдагдвал хорт хавдар, удамшлын өвчин үүсэх шалтгаан болдог байна. Эсийн хуваагдлын зохицуулгын туршлагын болон онолын судалгаанууд эрчимтэй хийгдэж байна. Бид эсийн хуваагдлын G,->S шилжилтэнд оролцох уургуудын харилцан үйлчлэлд санамсаргүй хүчин зүйлийн нөлөөллийг тооцох симуляци хийлээ. Шилжилтэнд СусЕ (СусЕ, Cyclin Е'), CDK2 (CDK2, Cyclin dependent kinas 2), CDC25 уургууд оролцох бөгөөд эдгээр уургуудийн хооронд явагдах нийт 14 урвалын магадлалыг бичив. Урвалуудаас хэдий хугацаанд, аль урвал явахыг Монте Карло аргаар санамсаргүй тоонуудаар сонгож олно. Уураг тус бүрийн концентрацийг Ω параметрийн тусламжтайгаар молекулын тоо ширхэгт хөрвүүлж, төлөвийн өөрчлөлтийн вектороор молекулуудын тооны өөрчлөлтийг олно. Энэ алгоритмаар Matlab, Fortran програмууд дээр код бичиж бодлоо. Энэхүү бодолтонд молекулуудын тооны өөрчлөлт нь Ω параметрийн бага утганд үед санамсаргүй хүчин зүйлийн нөлөө их, харин их утганд ялангуяа Ω=200 үед санамсаргүй хүчин зүйлийн нөлөө бага бөгөөд динамик загварын шийдтэй төстэй болж байлаа. СусЕ уураг задрах, CDC25 уураг задрах, хоёр фосфортой CDC25 уураг задрах урвалын явагдах магадлал бага байсан учраас хасаж бодуулав. Эндээс харвал урвалын магадлал хэдий бага боловч эдгээр урвал эсийн хуваагдалд чухал нөлөөтэй болох нь харагдаж байна.

Published: March 2023

Raman scattering spectra of the representative samples from Mongolian low metamorphic coal deposits as of Sharyn-Gol, Baganuur, Nalaikh, Alagtolgoi and Dovt were measured. Total carbon content of these samples was measured by X-ray microanalysis method. An existence of graphite-like domains in vitrinite of the low metamorphism coals has been revealed by the Raman measurements. A Raman amorphous A band at 1342-1364 cm-1 is less intense and broader than that of a graphitic G band at 1560-1580 cm-1 for all studied samples. The graphitic G band is found to be shifted to higher frequencies within 1560-1580 cm-1 with a decrease of coal maturity, while the Raman amorphousgraphitic band intensity ratio R=fA/fG is found to be increased.

Authors: Sridevi N. , Madheswari D.
Published: March 2023

Schiff base metal complexes are essential in modern coordination chemistry. It owns modern structural features and finds several uses in various fields, including pharmaceuticals, agriculture, dyeing, polymer science, food packaging, O2 detection, various biological systems, catalysis, and birth control. The Chemistry of Schiff base ligands and their metal complex increased, encompassing a wide range of organometallic compounds and bio-inorganic chemistry. Schiff bases belong to the class of organic compounds regarded as particularly significant. They have been investigated extensively in the past few years and have attracted much attention due to their appealing chemical and physical features. They are versatile and have a broader range of applications, such as anti-cancer, anti-fungal, anti-microbial, antiulcer, anti-tumor, anti-diabetic, herbicidal, anti-proliferative, and anti-inflammatory actions. The aim and objective of our research are to synthesize a series of five new Zn (II), Ni (II), Cu (II), Mn (II), and Co (III) of bis-3-(4.5-Dihydro-3 H-imidazol-4-yl)-2-[(4-methoxy-benzylidine)-amino]- propionic acid Schiff base metal complexes and to characterize those complexes by elemental analysis, UV-Visible, FT- IR, and Mass spectral studies. Bis-3-(4.5-Dihydro-3 H-imidazol-4-yl)-2-[(4-methoxy-benzylidine)-amino]-propionic acid ligand coordinates to metal ions as bidentate N and O donors. Biological studies of the synthesized Schiff base complex have also been investigated by anti-microbial, radical scavenging, docking study, anticancer analysis, and cytotoxic studies. Based on the analytical and spectral results, tetrahedral geometry has been tentatively proposed for all complexes except that of cobalt. The antioxidant studies of the Schiff base ligand and Schiff base complexes exhibit significant free radical scavenging activity against DPPH. Invitro cytotoxic activity of the Schiff complexes was evaluated against the over3 (ovarian) and melanoma cell lines (MCF14). The docking studies have been carried out using BSA protein and DNA biomolecules with synthesized metal complexes. Antimicrobial studies demonstrated the effectiveness against gram-positive and gram-negative bacteria.

O método construtivo em wood frame, que já é utilizado nos países desenvolvidos como Estados Unidos, Canadá e Alemanha, é sustentável, pois usa a madeira de reflorestamento para compor a estrutura. Neste contexto, este trabalho tem como objetivo comparar os sistemas construtivos wood frame e concreto armado. A comparação é feita por meio de um estudo de caso de uma edificação de médio padrão, no município de Relvado/RS avaliando as cargas exercidas nas fundações, os orçamentos considerando material e mão de obra para a estrutura e além disso, é feito um questionário a fim de avaliar a aceitação do sistema wood frame. O projeto estrutural em concreto armado foi o original da residência estudada, sendo desenvolvido o projeto estrutural em wood frame utilizando o software Dlubal Rfem. Foram feitos os orçamentos nos dois métodos construtivos, para o método convencional utilizou-se a tabela SINAPI não desonerada de fevereiro de 2022 e para o wood frame utilizou-se uma base de dados. Os resultados do questionário indicaram que 74% dos respondentes construiriam ou comprariam uma residência no método wood frame. A análise dos projetos estruturais indicou que a carga transmitida às fundações da estrutura em concreto armado é 56,54% maior que a estrutura em madeira. O orçamento das duas estruturas apontou que a estrutura em wood frame é mais econômica que a estrutura de concreto armado. Sendo assim, a estrutura em madeira se mostra uma alternativa ao sistema convencional em concreto armado.

Current global trends in the field of rapid population growth and urbanization have led to an increase in the labor market. The development of industrial cooperation has led to an increase in the number of science-intensive specialties resulting from economic activity, which has led to an increase in scientific and technological potential through the work of high-tech companies as well as to the emergence of some difficulties in the labor conditions of their employees (Beliakov et al., 2019; Blumen, 2015). The paper’s value relates to the possibility to increase the productivity and competitiveness of companies through employee satisfaction, as well as ensuring proper compliance with labor laws in the context of the legal link between the employer and the employee (Liashenko et al., 2021; Makedon et al., 2019). The international legal framework in the field of labor relations has been analyzed. The legislative experience of the United States of America, Great Britain, China, Ukraine, Portugal, and the Russian Federation in the implementation of the system of employee benefits and incentives has also been considered. The states were selected by the type of legal system based on the qualitative analysis method. The experience of some hi-tech companies in ensuring proper working conditions has been analyzed with the prospects for their implementation in Ukrainian realities
Analysis of tigecycline in cerebrospinal fluid and serum of patients with multidrug-resistant acinetobacter baumannii central nervous system infection by HPLC-MS/MS

Published: March 2023

Abstract Background This study aimed to establish a method to determine
tigecycline (TGC) in cerebrospinal fluid (CSF) and serum of 12 patients
with Multidrug-resistant acinetobacter baumannii (MDRAB) central nervous
system infection (CNSI) and evaluate the correlation of TGC in CSF and
serum samples. Methods TGC in CSF and serum was extracted by
acetonitrile and detected by HPLC-MS/MS. The separation was performed on
the Waters XBridge® BEH Shield RP18 column. This method could achieve
the quantification accurately in a very short time. Results For these 12
patients, the trough concentration ranges of TGC in CSF and serum at
steady-state were 16.35-53.56 ng/mL and 67.76-211.9 ng/mL. The
CSF-to-serum ratio of TGC at steady-state trough concentration was
ranged from 21.46% to 44.46%, and the mean value was 31.61 ± 8.13%.
The correlation of TGC in CSF and serum was 0.5065. CNSI might have no
potential to increase the penetration ability of TGC to CSF. Conclusion
The method was validated to be accurate and effective. The correlation
between the concentrations of TGC in CSF and serum at steady-state was
demonstrated to be positive based on quantification of TGC in
bio-samples from 12 MDRAB patients.

Published: March 2023

Simultaneous utilization and remediation of soils contaminated with
cadmium (Cd) is a propitious and economically beneficial task. Here, we
undertook a pot experiment with biochar application at four rates (0, 5,
10, and 15%, denoted as BC0, BC5, BC10, and BC15, respectively) with
the addition of 0.1% Cd, along with a control without Cd and biochar
addition (CK). Erigeron breviscapus, a raw medicinal material
used to extract scutellarin, was grown in all treatments to investigate
a new method of utilizing and remediating heavily Cd-contaminated soil.
The results showed that the high Cd-contaminated soil decreased the
yield and scutellarin content of E. breviscapus by 33.6% and
70.8%, respectively. Compared to BC0, the yield and scutellarin content
in BC15 increased by 24.7% and 312.0%, respectively. Biochar
application (BC5, BC10, BC15) changed the soil Cd speciation and reduced
the soil available Cd content by 17.4–121.8% and plant Cd content by
26.4–42.6% compared with BC0. However, chlorophyll content, catalase
(CAT) activity, and acquisition of N, Fe and Cu
of E. breviscapus increased in BC5, BC10,
and BC15 compared to BC0. Additionally, the mitigation effect of Cd
toxicity enhanced with increasing biochar application, and 15% biochar
application resulted in the highest yield and scutellarin content of
E. breviscapus. This study highlights the importance of biochar
for improving the Cd adaptability of E. breviscapus and provides
a reference for the simultaneous utilization and remediation of heavily
Cd-contaminated soil.

The sense of agency varies as a function of arousal and valence in
negative emotional contexts. As yet, it is unknown whether the same is
true for positive affect, and how inter-individual characteristics might
predict these effects. Temporal binding, an implicit measure of the
sense of agency, was measured in 59 participants before and after
watching either an emotionally neutral film clip or a positive film clip
with high or low arousal. Analyses included participants’ subjective
affective ratings, physiological arousal (pupillometry, skin
conductance, heart rate), and individual differences (arousal reactivity
via psychopathy, eye blink rates). Linear mixed models showed that low
arousal reactivity reduced the effect of high arousal on binding towards
actions. Low arousal reactivity reversed the effects of high arousal on
binding towards outcomes. These results provide evidence that individual
differences influence the extent to which the sense of agency is
affected by positive emotional states.
Social divisions and identity engineering of transitional cultural policy in Serbia
Authors: Djukic Vesna
Published: March 2023

Starting from the relationship to the government, we study the social
division into ?off-institutional? and ?institutional?, ?independent? and
?dependent? actors of cultural life in Serbia and their mutual interactions
within the four families of the transitional cultural system. Due to the
similarity with self-management in culture, we observe the phenomenon
through two time points that represent turning points in the conduct of
cultural policy based on the political, legal and financial authority of the
govern?ment acquired on the basis of election results. Empirical research is
based on interviews with actors of transitional cultural policy in Serbia
and contextualization of the content of internet presentations and media
texts. In addition to the comparative analysis, a nor?mative analysis of the
document ?Protocol on cooperation between the Ministry of Culture and the
Independent Cultural Scene of Serbia? (2011) was also applied, which is a
con?firmation of cultural hegemony and identity engineering by the
alternative model of cultural policy ?state double?. The results of the
research showed that this alternative model in 2011 obstructed the
decision-making system defined by law which does not provide for the
transfer of decision-making authority to an independent body; that the
independent scene is not aware of the joint responsibility for the
disastrous results of a weak state according to the Index of states
weaknesses in the developing world; that it uses the weaknesses of the
transitional cultural policy in order to achieve benefits for itself and
related organizations by excluding undesirable value systems in culture,
especially those that are the bearers of Serbian cultural identity.
Divorces in the republic of Serbia from 1950 to 2020 (demographic-statistical research)
Authors: Medojevic Jovo , Milosavljevic Sasa
Published: March 2023

The pursuit of married life is the result of the universal need of humanity.
Finding a close person with whom a person is bound by unbreakable bonds of
love is a significant factor in the life of every man and woman.
Traditionally, marriage is considered a lifelong social institution -
however, in the last seven decades, both in the world and in the Republic of
Serbia, marriage and family relations have undergone many and strong
changes. Modern demographic- statistical research indicates that in the past
seventy years (in the period from 1950 to 2020) complex demographic
processes took place in the Re?public of Serbia, initiated by strong
natural, socio-economic and external factors that unequivocally influenced
and today affect marriages, and thus the transition of marriages in the
Republic of Serbia. Qualitatively-Quantitative analysis determined: length
of marriage, age of spouse in case of divorce, divorces in relation to
education and spouse nationality. The research results show that men and
women are entering the marriage, but later divorce. When concluding and
divorcing a marriage, the difference in age between spouses is slightly more
than three years on average - men are most commonly older than women. Due to
long-term suffering of some form of violence, women most often initiate a
divorce. The length of marriage in the Republic of Serbia has an oscillatory
course. The average age of husband and wife at divorce is increasing. In the
structure of divorced marriages accord?ing to education, marriages with
secondary education are dominant. The most represented ethnic community in
divorces are Serbs as well as Orthodox in terms of confessions, due to their
majority share in the total population of the country.

Published: March 2023

Objectives

To compare the bleaching efficacy and tooth sensitivity (TS) of 4% hydrogen peroxide (HP) in adults using a continuous or fractioned protocol.

Methods and Materials

A single-blind randomized controlled trial with a parallel design was conducted. Eighty-six patients with upper canines A2 or darker were submitted to bleaching with 4% HP gel for three weeks after random allocation into the fractioned protocol (two 30-minute daily applications) or continuous protocol (single one-hour application). We evaluated the color change at baseline, weekly, and 30 days after the bleaching using Vita Classical and Vita Bleachedguide using the units of shade guides (SGU) and by spectrophotometer using CIELab 1976 (ΔEab) and CIEDE 2000 formulas (ΔE00), as well as Whiteness Index (ΔWID). We assessed the absolute risk of TS with a visual analog scale (VAS) and numeric rating scale (NRS). Color changes in each recall were compared with the Student t-test. The risk of TS was evaluated by the Chi-square test, and the intensity by Mann–Whitney test (NRS) and Student t-test (VAS).

Results

The mean difference for the ΔSGU Vita Classical (0.5; 95% CI: −0.5 to 1.5), ΔSGU Vita Bleachedguide (−0.4; 95% CI: −1.5 to 0.7), ΔEab (1.4; 95% CI: −0.1 to 2.9), ΔE00 (0.6; 95% CI: −0.4 to 1.6), and ΔWID (−3.2; 95% CI: −7.3 to 0.9) after three weeks of bleaching was not clinically or statistically significant (p>0.10). The absolute risk of TS was 44% (95% CI: 30–58%) and 46% (95% CI: 32–61%) in the fractioned and continuous protocols, respectively (RR=1.0; 95% CI: 0.6 to 1.5; p>0.91).

Conclusion

A fractioned bleaching protocol with 4% HP (30 minutes twice daily) did not increase the whitening degree nor affect the risk and intensity of TS when compared with the one-hour continuous protocol.
Westwards expansion of the European catfish Silurus glanis in the Douro River (Portugal)
Authors: Gkenas Christos , Martelo Joana , Ribeiro Diogo , Gago João , Santos Gil , Dias Diogo , Ribeiro Filipe
Published: March 2023

The current study reports the first occurrence and the spread of the European catfish Silurus glanis (Family: Siluridae) in the Portuguese section of the Douro River, suggesting a potential expansion of its distribution in Portugal either via westward dispersal across international rivers and/or human-assisted introductions into new reservoirs and drainages. The European catfish has unique features (e.g., opportunistic predator, hunting, and aggregation behaviour) that make it highly suitable for establishing self-sustaining populations in new areas and likely contribute to its invasion success. The species may severely affect native prey communities and modify food web structure and ecosystem functioning. Efficient and sustainable management actions are needed to prevent further introductions in the future.
Modifiye edilmiş ahşabın hızlandırılmış yaşlandırması: Isıl işlemli örnekler ile asetillendirilmiş örneklerin kıyaslanması
Authors: DİZMAN TOMAK Eylem , CAN Ahmet , ERMEYDAN Mahmut Ali , AYDIN Mehmet Ali
Published: March 2023

Bu çalışmada amaç, ısıl işlemli örnekler ile asetillendirilmiş örneklerin toprak üstü kullanım yerlerinde maruz kalabileceği UV ışığı başta olmak üzere dış ortamın bozundurucu faktörlerine karşı dayanıklılığının hızlandırılmış yaşlandırma testi ile belirlenmesidir. Bu amaçla ısıl işlemli çam ve dişbudak örnekleri ile asetillendirilmiş çam odunu örnekleri toplam 400 saat boyunca değişik döngülerde UV ışığı ve suya maruz bırakılmıştır. Örneklerin teste başladıktan 100, 200 ve 400 saat sonra renk ve yüzey kimyası (ATR-FTIR) analizi ile makroskopik açıdan değerlendirilmesi yapılmıştır. Sonuçlarda, ısıl işlemli örneklerin yaşlandırma test süresi uzadıkça koyu olan başlangıç renklerinin açılmaya başladığı ve toplam renk değişimi (∆E*) değerlerinin giderek arttığı bulunmuştur. Buna karşın asetillendirilmiş örneklerde ilk 100 saat sonrasındaki renk değişimi test süresince dikkate değer ölçüde değişmemiş ve test boyunca neredeyse stabil olmuştur. Asetillendirilmiş örneklerin rengi hafif açılma eğilimindedir. Kontrol çam ve dişbudak örneklerinde toplam renk değişimi test süresince hafif bir artış eğiliminde olup, en büyük değişim ilk 100 saatlik test süresinde gerçekleşmiştir. Bu örneklerin rengi test süresince koyulaşma eğilimindedir. 100 saat sonrasında kontrol çam ve ısıl işlemli dişbudak örneklerinde çatlaklar gözlenmiş ve test süresince bu çatlaklar giderek artmış ve derinlemiştir. Yüzey kimyası analizleri, örneklerdeki renk değişimini desteklemekle birlikte örneklerin lignininde yaşlanmanın ilk aşasından itibaren bozunmalar olduğunu göstermiştir. Hızlandırılmış yaşlandırma testinin bozundurucu faktörlerine karşı, asetillendirilmiş örnekler ısıl işlemli örneklerden, ısıl işlemli örnekler ise kontrol örneklerinden daha iyi bir performans sergilemiştir.

Öz – Bu çalışmada amaç, dut ağacı (Morus spp.) odun ekstraktiflerinin toprak üstü kullanım yerlerinde maruz kalabileceği UV ışığı başta olmak üzere dış ortamın bozundurucu faktörlerine karşı dayanıklılığının belirlenmesidir. Bu amaçla dut odun örnekleri öncelikli olarak sikloheksan/etanol (2/1) ardından aseton/su (7/3) ve son olarak da su ile toplam 21 gün boyunca üç aşamalı ekstraksiyona maruz bırakılmıştır. Ekstrakte edilen ve edilmeyen örnekler, denize yakın ve denize uzak 2 farklı alanda 6 ay süresince doğal dış ortam koşullarına bırakılmıştır. Örneklerin teste başladıktan 1, 3 ve 6 ay sonra rutubet miktarı, renk ve yüzey pürüzlülük ölçümleri, yüzey kimyası (ATR-FTIR) ve makroskopik açıdan değerlendirilmesi yapılmıştır. Sonuçlarda ekstraksiyon işlemi örneklerin başlangıç yüzey pürüzlülüğünü yaklaşık %50 oranında arttırmış ve rengini %4 oranında açılmasına neden olmuştur. Örneklerin yaşlandırma test süresi uzadıkça rutubet miktarının arttığı, ekstrakte edilen örneklerin ekstrakte edilmeyen örneklere, denize yakın alanda bekletilen örneklerin denizden uzaktaki alanda bekletilen örneklere kıyasla daha fazla rutubet miktarına sahip olduğu bulunmuştur. Ekstrakte edilmeyen örneklerde, yaşlandırma test süresince meydana gelen yüzey pürüzlülüğü, ekstrakte edilen örneklere kıyasla daha fazla olmuştur. Denizden uzak alanda bekletilen ekstrakte edilmeyen örneklerin pürüzlülüğü, denize yakın alanda bekletilen örneklere kıyasla daha fazla bulunmuştur. Yaşlandırılan örneklerde, test süresinin ilk 3 ayında ∆L* değerlerinde artma, daha sonra azalma, buna karşın ∆a* ve ∆b* değerlerinde ise azalma eğilimi gözlenmiştir. 1. ay ile 6. ay arasında toplam renk değişimindeki (∆E*) değişim ekstrakte edilmeyen örneklerde ekstrakte edilen örneklere kıyasla daha az bulunmuştur. Yüzey kimyası analizleri, örneklerdeki renk değişimini desteklemekle birlikte örneklerin lignininde yaşlanmanın ilk aşamasından itibaren bozunmalar olduğunu göstermiştir.

Hygiene assessment and dietary correction of vitamin D level in residents of the southern region of Ukraine
Authors: Shanyhin A.V. , Babienko V.V.
Published: March 2023

For most people, the best way to prevent vitamin D deficiency is to optimize your diet by using foods high in vitamin D. Adding foods high in vitamin D that are available in your area to your diet is a physiological way to prevent vitamin D insufficiency and deficiency. Which in turn, is an effective way to prevent the development of pathological conditions associated with a low level of vitamin D. Objective: To determine the level of prevalence of vitamin-D deficient states among residents of the southern regions of Ukraine. To assess the relationship between deficiency and insufficiency of vitamin D with actual nutrition and to develop recommendations for the prevention of such conditions. Materials and methods. 928 residents of the Southern region of Ukraine, aged from 19 to 82, were examined. The study consisted of two stages: assessment of the diet and determination of the level of 25(OH)D in the blood serum and dietary correction of the diet in patients with vitamin D < 30 ng/ml, by enriching the diet with products with a high content of vitamin D. The results of the study and their discussion: The level of 25(OH)D among the study participants was 4.31 – 89.19 ng/ml. Vitamin D was deficient in 312 patients, insufficient in 290 patients, and sufficient in 326 patients. 114 patients took part in the second stage of the study: The main group (n=63) – correction of vitamin D by enriching the diet with products containing vitamin D equivalent to 4000 IU/day. Control group (n=51) - correction of 25(OH)D level was not carried out. Conclusions. Vitamin-D deficient conditions are common among residents of Southern Ukraine. Correction of the diet due to products with a high content of vitamin D in an equivalent dose of 4000 IU/day is able to ensure a sufficient level of 25(OH)D in the blood serum.

Published: March 2023

The study investigates trans-language methods in teaching English. The research examines multilingual practices in the Ukrainian context from sociocultural and multimodal perspectives. Also, it is a desire to know how trans-language techniques can effectively enhance language acquisition. The data came from the Program of English Language Profile conducted in two Ukrainian Universities, aimed at giving students in the bachelor’s programs the opportunity to reinforce their multilingual and intercultural competencies in a second foreign language (English) within the first semester of 2021. The study analyzes the audio recording of students’ and teachers’ multilingual practices, questionnaires on students’ attitudes toward trans-language, and qualitative interviews with teachers. Results show how multilingual resources may facilitate intercultural communication and language development. The findings emphasize the importance of building natural multilingualism and making it a resource, strategy, and goal of teaching English. This study provides practical suggestions and techniques on how universities can adapt to formal teaching environments. Implementations show that trans-language processes become a set of multilingual practices whereby language teachers build on and use their students’ linguistic resources and background knowledge to convey meaningful content. This research develops ‘trans-language’ as an educational and linguistic concept and gives educators the ground to think critically about the advantages and limitations of adopting a multilingual approach.

Solusi Islam Terhadap Kasus - Kasus Rasisme
Authors: Kaslam Kaslam , Sulistiani Kurnia
Published: March 2023

Kasus-kasus rasisme yang pernah terjadi di Indonesia mayoritas disebabkan oleh perbedaan suku, etnis dan agama. Penyebab awal hanyalah permasalahan sepele antar individu yang kemudian melebar hingga menjadi sebuah kerusuhan massal. Islam sebagai agama yang universal tentunya memiliki solusi mengatasi permasalahan ini. Hasil penelitian menunjukkan bahwa terdapat banyak dalil-dalil Al Qur’an dan Hadits yang dapat menjadi rujukan untuk mencegah dan mengatasi kasus-kasus rasisme. Solusi islam dalam mengatasi kasus rasisme antara lain: larangan mengolok-olok suatu kaum;menanamkan konsep tauhid dalam diri kaitannya dengan habluminallah dan hablumninnas; menerapkan konsep satu keluarga dalam bingkai bernegara; menganggap perbedaan sebagai tanda kebesaran Allah Swt., yang harus dijaga; menanamkan dalam diri bahwa setiap manusia terlahir dalam keadaan mulia; dan islam datang sebagai rahmatan lil alamin yang mengayomi semua etnis dan suku. Dengan adanya solusi islam ini, diharapkan terjalin persaudaran yang kuat menuju negeri yang dicita-citakan yaitu baldatun, thayyibatun wa rabbun ghafur, sebuah negeri yang selaras antara alam dan kebaikan perilaku penduduknya.
KEPEDULIAN SOSIAL DALAM PERSPEKTIF HADIS
Authors: Mukhtar Mukhlis bin
Published: March 2023

Kepedulian sosial merupakan salah satu aspek dari ajaran Islam yang diajarkan Nabi saw. kepada umatnya yang tertulis dalam berbagai kitab hadis.  Dari hadis-hadis Nabi tersebut dapat dipahami bahwa setiap individu memiliki tanggung jawab.  Tanggung jawab yang diemban oleh setiap individu, mendorong lahirnya kepedulian dalam ruang lingkup yang luas, di antaranya sebagai berikut: Dalam ruang lingkup keluarga, Nabi saw. menuntun orang tua (ayah dan ibu) untuk peduli terhadap pembinaan dan pendidikan anaknya, begitu pula sebaliknya anak dituntun untuk peduli terhadap pembinaan dan pendidikan yang diberikan kepadanya. Dalam ruang lingkup tetangga, Nabi saw. berpesan untuk menumbuhkan kebiasaan berbagi dengan tetangga.  Kebiasaan berbagi akan melahirkan sikap saling kenal-mengenal, menjalin keakraban, tolong-menolong, bantu membantu dan juga memudahkan untuk medeteksi jika tetangga dalam kesusahan dan kesedihan.  Dengan demikian akan terbentuk ruang lingkup kepedulian sosial yang senantiasa menjunjung tinggi ukhuwah (persaudaraan) yang utuh tanpa ada sekat suku, bangsa dan agama.
SAHIFAH; EMBRIO PEMBUKUAN HADIS
Authors: Ngampo Muhammad Ali
Published: March 2023

Bentuk awal hasil dari kodifikasi tersebut adalah S}ah}i>fah, kemudian s}ah}i>fah–s}ah}i>fah tersebut dibukukan ke dalam kitab–kitab hadis, yang hingga sekarang digunakan para ulama untuk menetapkan atau mengambil sebagai hujjah kedua setelah Al Quran. Maka penting untuk meneliti tentang keadaan shahifa ini. Penelitian menemukan bahwa para sahabat dan tabiin menjadi satu-satunya agen, yang dengan perantaraan mereka pengetahuan andal mengenai diri nabi saw. (sunnah) dan al-Qur’an dapat ditransmisikan. Artinya, tanpa peran aktif mereka dalam proses perekaman dan penyebaran hadis -salah satunya dengan membuat sahifah-, maka sangat boleh jadi seluruh jejak sunnah akan hilang, tanpa dikenali oleh generasi sesudahnya. Sahifah yang di tulis pada masa Nabi sangat berpengaruh terhadap munculnya berbagai macam kitab hadis, kemunculan kitab hadis memudahkan para peneliti hadis karena kitab-kitab tersebut telah disusun berdasarkan tema-tema tertentu sedangkan shahifah yang dulu ditulis oleh para sahabat masih dalam bentuk catatan prbadi dan belum dikelompokkan berdasarkan tema.
