Published: April 2023

Esse estudo objetivou discutir a mediação pedagógica e as novas tecnologias, os avanços e as estruturas utilizadas nas práticas de ensino. Trata-se de uma revisão narrativa de literatura científica sobre diferentes aspectos, funções e propriedades desempenhados pelas novas tecnologias e mediação pedagógica. A discussão perpassa pela complexidade das relações na sociedade atual e as mudanças que ocorrem na educação devido à existência das tecnologias. A escola é vista como um centro de alfabetização tecnológica, que introduz os educandos em uma realidade digitalizada. Os estudiosos citados defendem a ideia de que existem “nativos digitais” e “imigrantes digitais”, os primeiros sendo jovens que nasceram e cresceram com as Tecnologias da Informação e Comunicação (TICs), e os segundos, pessoas que migraram para o mundo digital. Embora muitos estudantes estejam inseridos em um contexto digital, nem todos têm acesso às tecnologias devido às suas condições financeiras. Assim, a escola precisa buscar formas de incluir e promover o acesso dos menos favorecidos ao mundo digital, reinventando seus métodos e utilizando e implementando as TICs como prática pedagógica. A tecnologia deve ser vista como uma ferramenta integrada na mudança estrutural da ação educativa, permitindo que educadores e educandos aprendam de uma maneira mais significativa e contextual cada assunto que estudam. Por fim, o texto destaca a importância da ressignificação e atualização do papel do professor nesse contexto pós-moderno.

Paul and Church Leadership: Towards an African Transformational Interpretation of Titus1:1-9 for the Rwandese Church
Authors: Mugiraneza Emmanuel
Published: April 2023

The scripture text from Titus 1:1-9 is a model that provides guidelines for selection and qualification of leaders in church administration. The purpose of this paper is to investigate leadership based on the scripture according to Titus through the lens of an African transformational interpretation and in light of the Rwandan church leadership. The evidence that challenges the leadership of the church in Rwanda can be drawn back from the 1994 genocide attack committed against Tutsis where some church leaders were unable to resist the tragedy while others participated in it. This is contrary to Titus 1:1-9 vis –a- vis the qualities of a leader. Through the African transformational interpretation applied to Titus 1:1-9, Rwandan church leadership must select and appoint leaders without reproach who can make an influential move using the similar core Christian characters shown in the scripture. This can serve as an apostolic manual for building a church that will survive in whatever circumstances that portrays the glory of God.

Enhanced methane hydrate formation using promoters for natural gas storage and transportation application
Authors:   , Inkong Katipot
Published: April 2023

Solidified natural gas (SNG) is an alternative technology for natural gas storage and transportation in the clathrate hydrate formed. It has higher volumetric energy storage with the ease to handle not to mention its safety. Effects of different hydrate promoters, including methyl ester sulfonate (MES), tetrahydrofuran (THF), hollow silica (HS), and sodium dodecyl sulfate (SDS), on the methane hydrate formation was investigated. All experiments were performed in an unstirred tank reactor at desired experimental conditions. The results indicated that all promoters significant enhanced the hydrate formation both kinetics and methane uptake compared with pure water. The increase in the MES concentration decreased the induction time and increased the hydrate formation rate, which was the result from the decrease in the surface tension between gas and liquid phase. The methane uptake increased with the increase in the MES concentration. The presence of THF shifted the hydrate phase equilibrium curve to the higher temperature and lower pressure. The results showed that the increase in the experimental temperature increased the methane uptake due to the effective heat distribution to the surrounding, while the hydrate formation kinetics decreased due to the decrease in the driving force. The decrease in the pressure did not affect the methane uptake but the hydrate formation kinetics decreased. There was synergism between THF with MES in the hydrate formation kinetics at the higher temperatures. Moreover, the presence of HS improved the surface contact area to enhance the hydrate formation at moderate conditions. The presence of SDS facilitated the hydrate formation, including induction time and hydrate formation rates, at moderate conditions.
Development of cellulose as substrates for adsorbents and sensors
Authors:   , Klahan Jadetapong
Published: April 2023

This thesis deals with two parts of development of novel sensors based on cellulose substrate platform. The first part is the development of fluorescence sensors and adsorbents for metal ions using bacterial cellulose as the platform. The second part is the development of colorimetric sensors for smartphone detection of oil marker using filter paper as the platform.

In the first part, bacterial cellulose (BC) has several advantageous properties over plant cellulose such as high purity, high surface area, high porosity, and high water-holding capacity due to its three-dimensional network of nanofibrils structure, that make BC appealing for applications related to surface capacity. In this work, BC is utilized as a substrate for immobilization of a 2-chloro-N-(quinolin-8-yl)acetamide (QA) via a nucleophilic substitution reaction using K2CO3 as a base. The QA modified BC film exhibit green fluorescence turn-on emission upon addition of Zn2+. The metal ion adsorption study by the ICP-OES analysis showed the adsorption capacity of 38.2 and 56.8 mg/g for Zn2+and Cd2+, respectively. The functionalized BC sheet is thus potentially useful for detection of Zn2+ and retrieving or removal of Zn2+ and Cd2+ from aqueous solution.

In the second part, a convenient method for sensitive detection of gasoline marker using a smartphone camera and image processing application are developed. Phenolphthalein (PhP) is used as a colorless dye marker in commercial gasoline. The color was developed by the interaction of PhP with NaOH on filter paper strips and evaluated based on the CMYK color system by ImageJ program. The counter-flowing technique, in which a gasoline sample and NaOH solution are allowed to travel on a filter paper strip from the opposite end, give the naked eye detection concentration of PhP as low as 1 ppm with the LOD of 0.31 ppm using a smartphone camera. The high sensitivity is attributed to the preconcentration derived from accumulation of PhP at the immiscible liquid interface. The counter-flowing method can thus be a new facile analytical technique for enhancing chemical detection sensitivity.

Authors:   , Thadasri Pornnutcha
Published: April 2023

Catalyst was constructed in form of microreactor by fused deposition modeling (FDM) or 3D printing method that allow micro scale customization in order to achieve high detail construction. Poly (lactic acid) (PLA) and Poly (acrylonitrile-butadiene-styrene) (ABS) filaments were used as a built-up material. The surface modification was introduced to improve filaments surface adhesion by using alkaline treatment and Polyethyleneimine with variation of time and concentration and then deposited with polyelectrolyte multilayers by layer-bylayer technique before catalyst loading. Catalyst were synthesized by reduction reaction of Silver nitrate (AgNO₃) and sodium borohydride (NaBH4) with using poly (4-styrenesulfonic acid-co-maleic acid) as a capping agent to produce silver nanoparticles that is supercatalytic. Catalyst loaded filaments were 3D printed out to characterize various properties by Field scanning electron microscopy (FESEM), Peeling test, Universal testing machine (UTM), Fourier-transform infrared spectroscopy (FTIR), X-Ray Diffractometer (XRD). Alkaline and Polyethylenimine can effectively increase built up materials surface adhesion resulting in increasing of silver nanoparticles attachment significantly.
Solid-Liquid-Polymer Mixed Matrix Membranes for Gas Separation: Silicone Rubber Membranes Filled with NaX and KY Zeolites Adsorbed PEG
Authors:   , Boonchoo Sitthikiat
Published: April 2023

Carbon dioxide (CO₂) is one of the major constituents of natural gas and biogas. The presence of high CO₂ content causes some serious problems including reduction of heating value and corrosion of equipment’s surface. Additionally, CO₂ emission is the main issue of the greenhouse effect. In consequence of these problems, membrane technologies have drawn much attention as potential techniques for gas separation. mixed matrix membranes (MMMs) have been studied and developed to provide the synergistic effect of inorganic and organic materials on membranes. In this study, PEG/NaX:KY/SR mixed matrix membranes (PZS MMMs) were prepared by the solution casting method using NaX and KY zeolites as the solid fillers, PEG as the liquid additive, and silicone rubber as the continuous phase. The fabricated PZS MMMs were evaluated through permeance and selectivity for the single gas measurements using a membrane testing unit at room temperature and a pressure of 50 psig. The combination of NaX and KY zeolites showed the improvement in gas separation CO₂/CH₄ gas separation. The PZS MMM with NaX/KY zeolite mass ratio of 0:1 yielded the highest CO₂ permeance and CO₂/CH₄ selectivity among the solid-polymer MMMs prepared. KY zeolite was more effective than NaX zeolite in term of higher CO₂ permeability and CO₂/CH₄ selectivity due to the basicity. PEG adsorbed into the zeolites effectively influenced the gas separation performance, CO₂ permeance and CO₂/CH₄ selectivity in comparison between solid-polymer and solid-liquid-polymer mixed matrix membranes.

Authors:   , Than Yee
Published: April 2023

Fused deposition modelling (FDM) based 3D printing technology for oral solid dosage form has shown promising results in the fabrication of individualized tablets compared to conventional method. However, the main concern of this technique is the quality of drug loaded filament including mechanical properties such as flexibility, stiffness and brittleness. To cope with these problems, filaments were produced via hot melt extrusion (HME) by screening and characterizing a series of pharmaceutical mixtures (6 types of polymers and 5 types of disintegrants) and processing parameters for specifying the design space in Design of Experiment (DoE). Therefore, the purposes of the present study were to develop and optimize the extended and immediate release FDM printed tablets using DoE. Solid state characterizations of extruded filaments and printed tablets were performed to understand the critical material and process attributes. The results showed that hydroxy propyl cellulose (HPC)-blended filaments can significantly improve their flexibility. All manufactured filaments and tablets possessed adequate quality attributes such as physicochemical, rheo-mechanical properties and desired drug release profiles. Further, the effect of formulation compositions on drug release and the optimized formulation were investigated by the statistically D-optimal mixture design. The optimized formulation of extended release tablets composed of 10% IMC: 49.5% HPC: 19.09%  PVP/VA:  20.94% SLP which resulted in the desired drug release at 4, 12 and 24 h while that of immediate release tablets contained 30% THY: 35% EPO: 20% HPC: 15% SSG with 85% drug release within 30 min. Consequently, this study suggested that the formulation development of oral drug delivery with the required drug release pattern can be achieved by a quality by design approach which could be extended to other HME-FDM applications in pharmaceutical area.
Effect of 2-(4”-hydroxybenzyl)-5-2”-dihydroxy-3- methoxystilbene on apoptosis and autophagic cell death of lung cancer cells
Authors:   , Tungsukruthai Sucharat
Published: April 2023

The shifting of autophagy, a catabolic process for cell survival, toward death could be a potential mode of anti-cancer drug action. In addition, autophagic cell death (ACD) is an alternative death mechanism in resistant malignant cancer cells. This study, we demonstrated how PE5, a stilbene compound, exhibits potent ACD-promoting activity and apoptosis in lung cancer cells that may offer an opportunity for novel cancer treatment. It was found that PE5 exerted a higher toxic effect toward cancer cells compared with its effect on normal cells. Interestingly, the cell death caused by PE5 was found to be concomitant with dramatic autophagy induction as indicated by acidic vesicle staining, autophagosome and by the LC3 conversion. We further confirmed that the main death induction caused by PE5 was via ACD, since the co-treatment with an autophagy inhibitor could reverse PE5-mediated cell death. Furthermore, the defined mechanism of action and upstream regulatory signals were identified using proteomic analysis. Time-dependent proteomic analysis showed that PE5 affected 2,142 and 1,996 proteins after 12 and 24 h of treatment, respectively. Among these, the crosstalk network comprising 128 proteins that control apoptosis and 25 proteins involved in autophagy was identified. Protein–protein interaction analysis further indicated that the induction of ACD was via AKT/mTOR and Bcl-2 suppression. Western blot analysis confirmed that the active forms of AKT, mTOR and Bcl-2 were significantly decreased in PE5-treated cells. Taken together, we demonstrated the novel mechanism of PE5 in shifting autophagy toward cell death induction by targeting AKT/mTOR and Bcl-2 suppression.
Effect of ovalitenone on non-small cell lung cancer cells
Authors:   , Sanookpan Kittipong
Published: April 2023

Cancer metastasis is the major cause of about 90% of cancer deaths. As epithelial-to-mesenchymal transition (EMT) is known for potentiating metastasis. In the present study aimed to elucidate the effect of ovalitenone on the suppression of EMT and metastasis-related behaviors, including cell movement and growth under detached conditions, and cancer stem cells (CSCs), of lung cancer cells. Ovalitenone, as a flavonoid was extracted from roots of Millettia erythrocalyx Gapnep., was the first reported to show the anti-migration activity of H460 and A549 lung cancer cells. Ovalitenone was used at concentrations of 0–200 μM. While it caused no cytotoxic effects on lung cancer H460 and A549 cells, ovalitenone significantly suppressed anchorage-independent growth, CSC-like phenotypes, colony formation, as well as the ability of the cancer to migrate and invade cells. The anti-migration activity was confirmed by the reduction of filopodia in the cells treated with ovalitenone. Interestingly, we found that ovalitenone could significantly increase the level of E-cadherin, whereas it decreases the levels of N-cadherin, Snail, and Slug, indicating EMT suppression. Additionally, ATP-dependent tyrosine kinase (AKT), and the mammalian target of rapamycin (mTOR) were suppressed by ovalitenone. The results suggest that ovalitenone suppresses EMT via suppression of the AKT/mTOR signaling pathway. Furthermore, ovalitenone exhibited potential for the suppression of CSC phenotypes. These data reveal the anti-metastasis potential of the compound and support the development of ovalitenone treatment for lung cancer therapy.

This study aimed to examine the differences in mechanical and physical properties of Ti-6Al-4V extra low interstitial (ELI) fabricated by selective laser melting (SLM) between different laser power. The Ti-6Al-4V ELI alloy samples were printed in dumbbell shape by SLM machine (Trumpf/TruPrint 1000, Germany) with 3 laser powers (75, 100 and 125 W), 8 samples for each group. And the other parameters (spot size 30 µm, scanning speed 600 mm/s, layer thickness 30 µm) were kept constantly. All samples were performed under tensile test with universal testing machine. Moreover, The microhardness test was performed.  All data were statistically analyzed with one way ANOVA and Tukey’s post-hoc tests (α=0.05). The microstructure was analyzed by optical microscope and mode of failure was observed by SEM. It was found that the group laser power 100 W was the highest mean tensile strength (1189 .67 MPa) and highest mean microhardness (394.94 VHN). The tensile strength in group laser power 75 and 125 W were 424.62 and 329.88 MPa, respectively. And microhardness value in group laser power 75 and 125 W were 368.3 and 369.62 VHN, respectively.   Mode of failure after tensile testing in group of laser power 75 and 100 W showed in both ductile and brittle fracture. And the group of laser power 125 W was predominantly brittle fracture. In conclusion the difference in laser power effected the mechanical and physical properties. The laser power 100 W showed the highest mean tensile strength and microhardness significantly compared to the other 2 groups (α=0.05). And this group was found the α’ martensitic phase microstructure.
Effects of sexism and self-construal on women's mental intrusion and autobiographical memory
Authors:   , Kambhu Natta
Published: April 2023

This online experiment aims to examine self-construal as a moderator to prevent negative effect, namely, mental intrusions and autobiographical memory about being incompetent, from hostile and benevolent sexism. Thai female undergraduates (N = 89) aged between 18 to 24 (M = 20.30, SD = 1.30) were recruited through convenience sampling technique. Participants were randomly assigned to either benevolent sexism or hostile sexism condition followed by one of the three self-construal written task (independent, interdependent, or no self-construal conditions). Participants completed a set of short-term memory question in order to assessed their mental intrusions during the time completing the task and were asked to recall about the time they felt incompetent and listed it out.

A Multivariate Analysis of Variance (MANOVA) was conducted to examine the influence of sexism (hostile vs. benevolent) and self-construal (interdependent vs. independent VS. no self-construal) on female mental intrusions and autobiographical memory, the interaction effect was significant for autobiographical memory, (F(2, 83) = 3.38, p < .05), but not mental intrusions (F(2, 83) = 1.06, p = .351). However, self-construal manipulation was only help reduce mental intrusions and autobiographical memory about being incompetent in the hostile sexism but not the benevolent sexism. The best self-construal treatment for the hostile sexism condition was interdependent self-construal as participants in this group scored highest in short-term memory task (M = 26.61, SD = 5.58), reported lowest mental intrusions (M = 3.22, SD = 1.40) and autobiographical memory (M = 7.56, SD = 4.39). It could imply that hostile sexism directly attacks female and interdependent self-construal motivated them to complete the task for their gender group. While benevolent sexism seems to work best with control task of self-construal because their performance were better (M = 25.42, SD = 4.18) and level of mental intrusions (M = 3.17, SD = 0.73) and autobiographical memory (M = 8.69, SD = 5.27) were lower than other conditions. The outcomes suggested that control task might help participants to focus on unrelated topics instead of ambiguous benevolent sexism text.

Authors:   , Bowornkittikun Anchidtha
Published: April 2023

The present study was purposed to explore a theoretical model hypothesized to explain the relationship between bullying victimization and depressive mood with self-compassion and resilience as mediators. Participants were 371 junior high school students in the Bangkok metropolitan area. The participants' mean age was 12.95 years old. Participants were predominantly males and responded to the study measures online. Data obtained were analyzed using a path analysis on SPSS AMOS. The proposed theoretical model did not fit with the empirical data; hence, a model modification was conducted. Results indicated a good fit, (X2 (2, N=371) =2.42, p=.09). Self-compassion and resilience mediated the relationship between bullying victimization and depressive mood. Findings implications were discussed in terms of the therapeutic preventions and intervention for reducing depression in adolescents.

Authors:   , Taworntawat Chirra
Published: April 2023

Background: Globally, major depressive is the primary cause of disability. A large part of cases is reported among the working-class. Literature reviews suggest that the disorder is tied in with immune dysregulation and inflammatory response. This study aimed to assessed MCS (mindfulness meditation + curcumin supplementation + sunlight exposure) program by comparing with a control group among mildly depressed office workers.

Methods: A quasi experiment was conducted with a total of 68 male and female office workers, n=34 being treatment group (TG) and n=34 being control group (CG). The groups were compared in terms of (a) serum brain-derived neurotrophic factor (BDNF), (b) serum interleukin-6 (IL-6), (c) serum 25-hydroxyvitamin D (vitamin D), and (d) depression scores of PHQ-9. Multiple Linear Regression and Fixed Effect Model were used to test effects of the intervention.

Results: BDNF values differ significantly at base line but saw a sudden rise in [day 0, day 30] interval and a decline in [day 30, day 60] interval in CG. IL-6 outcomes at baseline showed no significant differences between groups, and the combined groups saw a modest but significant increase in [day 0, day 30] interval and a decrease in [day 30, day 60] interval. Notably, IL-6 was significantly lower in TG at day 30 than CG (P<0.05). For vitamin D, the rates of increase in both [day 0, day 30] and [day 30, day 60] intervals were significantly higher in TG than CG (P<0.05). In addition, there were significant differences between the groups at day 30 and day 60 with no notable confounding factors for vitamin D. Depression scores of TG demonstrated an appreciable decline in [day 0, day 30] interval and stayed down until the end of the study whereas of CG saw no changes throughout the study. Moreover, lower depression scores were observed for TG at both day 30 and day 60 (P<0.05).

Discussion: MCS program resulted in significant decreases in depression scores, a rise in vitamin D, and a drop in IL-6, thus can be a successful and inexpensive approach to alleviating depressive symptoms for depression among the working-class.

This study aims to detect herding behavior during the COVID-19 pandemic, compare investor trading behavior pre (2015 to 2019) and post (2020 to 2022) pandemic, and examine how investors react in panic and uncertainty. Current asset pricing theory states that cross-sectional returns should reflect systematic risks like stock prices, where Capital Asset Pricing Model (CAPM) betas are often viewed as return volatility, but they do not account for price volatility. To reflect the uncertainty, CAPM and Asset pricing theory are not sufficient so the gap is filled by behavioral finance that examines investors’ personalities and trading behaviors to explain market swings. It examines which stock price data influences investors’ decisions that is depicted by herding behavior. People “herd” when they do not make individual decisions. Unpredictability, worry, and panic often cause such behavior and COVID-19 epidemic worsened such factors that hurt global economy and stock markets. Financial data cannot reveal herding behavior for which two models, Cross-sectional standard deviation (CSSD) and Cross-sectional absolute deviation (CSAD), acknowledged by Christie and Huang (1995), are used to identify herding behavior in Bangladesh’s capital market during the COVID-19 pandemic. CSSD uses standard deviation to understand investor herd behavior, while CSAD uses absolute deviation. As mentioned in the literature review from the journal of Christie and Huang (1995) that the CSSD model and CSAD model will provide a conflicting result, the above finding shows the same because in CSSD model, no herding behavior is found but in the CSAD model, the herding behavior is found in the bullish markets for the year 2020 and in the bearish markets from 2015 to 2022.

Published: April 2023

Recently, there has been widespread interest in innovation through ICT for development (ICT4D) projects focusing on the poor communities in developing countries. This study conceptualizes ICT innovation challenges as a source of ambiguity and freedom to reflect during innovation process. It is argued that entrepreneurs take advantage of such experiences and start to look for options to transform traditional practices for ICT innovation. The study illustrates that ICT innovation in developing countries is a process of path creation involving three practices: experimenting and exploring ideas in real time, disembedding traditional practice, and mobilizing actors through translation. Such practices are explored in an ICT innovation initiative in Bangladesh. Drawing on the findings, theoretical implications in understanding the entrepreneurial process through which ICT innovation in developing countries can be successful have been discussed and several practical implications for entrepreneurs have been outlined.

Fintech has emerged with transformative potential to impact financial growth and stability in any nation. While extant literature has steadily grown in scope and depth on fintech adoption factors and their impact on financial inclusion, a cross-country perspective is still largely missing. In this study, we conducted a qualitative research to examine the current situation of Fintech ecosystems in 18 developing nations selected based on World Bank GNI per capita categorization. We have compared these nations according to parameters taken from the literature which include population, median age, GNI per capita, literacy rate, mobile phone connections, number of internet users, unbanked population, investment in fintech, number of fintech companies, and regulation. A cornerstone measurement throughout our analysis was country ranking from Global Findexable Ranking 2021. The findings suggest that nations with high populations, median age, GNI per capita, literacy rate, mobile phone connections, internet usage, number of companies, investment, and low unbanked population enjoyed higher fintech ranking. Countries with highly regulated fintech industries like India, China, and Indonesia have been at the top of the ranking. A notable exception here is Vietnam, which has actually slipped down the rankings from the previous year. The paper provides a number of policy recommendations based on the exploratory findings for fintech ecosystems in developing nations in general and the ecosystem in Bangladesh in particular.
The Descendant of Shishmanids – A Real or Imaginary Participant in the First Tarnovo Uprising of 1598
Authors: Krastev Krasimir
Published: April 2023

In Bulgarian historiography a thesis has been maintained that during the First Tarnovo Uprising, which broke out in 1598, the inhabitants of the old Bulgarian capital of Tarnovo had proclaimed an imaginary descendant of the Shishman dynasty under the name of Shishman III as a tsar. In other cases, this person is identified with Theodore Balina. This article aims to prove that these conclusions are not based on any scientific evidence, but are a the result of a series of misunderstandings and errors that have been reproduced to our own day.
Prophecies and Facts in One Notice from the Belyakovets’ Chronicle
Authors: Petrova Denitsa
Published: April 2023

The article examines a short extensive report in the 16th-century Belyakovets’ Chronicle (NLCM 309), which combines prophesies and facts. The information, which has not been a subject of a special study so far, tells of an eclipse and a comet as harbingers of the death of Prince Lazar Hrebeljanović in the battle of Kosovo. Some of the information is contained in other short chronicles but the prophesy is not derived from them. The note uses hagiographic works as a source, including the Lives of Lazar Hrebeljanović and of Stefan Lazarević. The supplement shows the attitude of the writer, who seeks to enrich the text and looks for the reasons for the described events. It is also a testimony to the dynamics of the Bulgarian-Serbian literary relations and to the respect for the Serbian saints, conceived as martyrs for the faith.

Published: April 2023

Pas prezantimit të një historie të shkurtër të këtyre regjistrimeve të bëra gjatë shekujve, ky punim shqyrton demografinë e zonës së Dibrës nga Periudha e reformës së Tanzimatit (1839) deri në vitin 1858, periudhë në të cilën Dibra ishte një pjesë administrative e sanxhakut të Ohrit të Vilajetit të Rumelisë dhe ndahej në Kazanë e Dibrës së Sipërme dhe në Kazanë e Dibrës së Poshtme.

Gjithashtu në bazë të këtyre regjistrave është analizuar struktura demografike dhe faktorët ndikues në këtë strukture, ku nëpërmjet të dhënave të këtyre regjistrave bëhet e mundur pasqyra nga numri i përgjithshëm i shtëpive, numri i popullsisë dhe klasifikimi i kësaj popullate në kategori sipas moshës ose pasurisë.

Gjatë analizës, këto të dhëna i kemi llogaritur në përqindje, duke mundësuar krahasimin e demografisë së viteve të marra në studim.

Sa i përket zonës së marrë në studim, mund të thuhet që nuk ka ndodhur regjistrimi i vitit 1831. Regjitrime të popullsisë së kësaj zone në funksion të realizimit të reformave të Tanzimatit, i përkasin periudhës kohore midis viteve 1845-1858, ku Dibra kishte statusin e kazasë dhe administrativisht bënte pjesë në Sanxhakun e Ohrit të Vilajetit të Rumelisë. Në këto deftere Dibra ishte e ndarë në Kazanë e Dibrës së Sipërme dhe në Kazanë e Dibrës së Poshtme.
Mbi disa lloje të ligjërimit në Kuran
Authors: Suma Dr. Rexhep
Published: April 2023

Libri i shenjtë, Kurani Famëlartë, është fjalë e Allahut (xh.sh.) që e  ka zbritur në periudhën kohore prej 23 vitesh mbi të Dërguarin e fundit, Muhamedin (a.s.). Si i tillë, ai ka sfiduar botërat dhe çdo krijesë. Kurani përçon në vetvete jetë, ilustrim dhe frymëzim shpirtëror dhe qenia njerëzore e ka të pamundur të japë shpjegimin mbi sekretin e këtij fenomeni. Fjalët e tij dëshmojnë mjaft mirë, se është e pamundur të imitohet Kurani dhe stili i rrëfimeve të tij është i paarritshëm.

Kurani i dhuron myslimanit vizion të plotë dhe program të qartë, të ngjeshur dhe jetën ia bën të ecë në vijën e ekuilibruar, duke mos u ndeshur me asgjë tërë kohën. Ky vizion, po ashtu, e unifikon diturinë me besimin, duke bërë që njeriu, pas materies, të jetë përsëri me materien. Po ashtu, ky vizion lidh sekretet me emocionet e ndjeshme dhe asnjëherë nuk i lë ato që të ndahen. Është tashmë e ditur që, nëse ne do t’i përmbahemi vizionit kuranor dhe do të meditonim për shenjat e Zotit te krijesat, do të kishim një psikologji e cila do të njihte madhështinë e Krijuesit, që kur e ka krijuar njeriun.
