Let’s Get Sociotechnical: A Design Perspective on Zero Energy Renovations
Authors: Boess Stella
Published: April 2022

The scaling up of zero energy (ZE) renovations contributes to the energy transition. Yet ZE renovations can be complex and error-prone in both process and outcome. This article draws on theory from sociotechnical design, participatory design, and inclusive design to analyse four recent case studies of ZE renovation/building in the Netherlands. The cases are studied using a mix of retrospective interviews and workshops, as well as ethnographic research. Three of the cases studied are ZE renovations of which two are recently completed and one is in progress, while the fourth case is a recently completed ZE new build. Three of the cases are social housing and one is mixed ownership. The research enquired into the situation of the project managers conducting the processes and also drew on resident experiences. The ZE renovation/builds are analysed as sociotechnical product-service systems (PSSs). The article evaluates how the use values, product values, and result values of these PSSs emerged from the processes. This perspective reveals issues with the usability of the PSSs, as well as with cost structures, technical tweaks, and maintenance agreements. Applying a design perspective provides starting points for co-learning strategies that could improve outcomes. Two example strategies that have potential in this regard are described, using demo dwellings and user manual as PSS prototypes in the early design phase. These and similar strategies could support the professionals in the field in creating successful ZE renovation/building processes.

El principio iura novit curia en el sistema procesal romano.
Authors: Gil García María Olga
Published: April 2022

Respecto a este aforismo, la doctrina romanista entiende que se presume que el juez conoce el derecho, e incluso que en la mayor parte de las ocasiones lo aplica. Sin embargo, esto no siempre es así en todas sus etapas, lo ideal, es que el proceso y su solución se adopten conforme a derecho; y es más que éste sea conocido por el juez cuando emite su sentencia. En este estudio revisamos los distintos sistemas procesales romanos, para analizar si de facto es de aplicación tal principio en Derecho romano y como consecuencia dónde podemos encontrar su posible origen.
La monogamia como fundamento de las estructuras conyugales en los sistemas jurídicos occidentales: un aporte romanístico
Authors: Lázaro Guillamón Carmen
Published: April 2022

Este trabajo pretende poner de manifiesto que el principio monogámico es característico del matrimonio romano. Desde este contexto, comprender e integrar los principios de las estructuras conyugales del Derecho Romano y seguir su iter histórico-jurídico es esencial a fin de fortalecer el principio monogámico que informa el actual sistema, puesto que dicho principio ofrece las bases tanto de la estructura familiar privada, como de la ordenación y la gestión de lo público en los denominados Estados Sociales y Democráticos de Derecho.

Published: April 2022

La expresión supra cerebrum que el Emperador Justiniano atribuye a Juvencio Celso en CJ. 6.22.10.3 no tiene equivalencia en todo el Corpus Iuris Civilis y su explicación, aunque intuitiva, no puede llevarse a cabo únicamente desde una perspectiva jurídica. En este artículo, sostenemos que la ciencia médica atribuía al cerebro la audición y que cerebrum, en la fuente objeto de análisis, ha de ser traducida como “cabeza”.

The 2014 Zigui Earthquake Sequence near the Three Gorges Dam in China
Authors: Huang Rong , Zhu Lupei , Xu Yixian , Tang Chi-Chia , Wen Hongbin
Published: April 2022

Seismicity in the Three Gorges Reservoir (TGR) region increased noticeably as the water level of the reservoir rises, since the Three Gorges Dam (TGD) was built in 2003. Here, we determined moment tensors of six earthquakes in the 2014 Zigui earthquake sequence (ZGS) in the TGR region using local and regional broadband seismic waveform data. We also determined the focal depth of the mainshock using its teleseismic waveform data and then relocated the epicenter using its travel times at local stations. High-precision locations of 64 events in the sequence were obtained by combining the double-difference relative location result and the mainshock’s absolute location. The event locations and moment tensor solutions indicate that the ZGS occurred between depth 5 and 9 km on a previously unknown fault striking southwest and dipping ∼80° to the northwest. The event depth distribution and coulomb stress change estimation suggest that the ZGS were not induced directly by the reservoir water but triggered by the stress change from the annual reservoir water level variation. We estimated that the newly found fault has the potential for a magnitude 5.7 earthquake for which ground motion has a 16% probability to exceed the designed maximum intensity level at the TGD, though it would take more than 100 yr to accumulate the needed amount of slip.

Published: April 2022

E-learning was a major study area during COVID-19 pandemic. Practically, public and private higher education institutions worldwide have switched from traditional face-to-face teaching to online learning solutions in order to deal with the spread of the coronavirus. Hence, the purpose of this study is to evaluate the effectiveness of the e-learning solution during COVID‐19 crisis. The research data were gathered using a self-administered online survey from Moroccan public university students. Through using the structural equation modeling under the partial least squares (PLS-SEM), the findings reveal that instructor quality has a direct and significant influence on system use and learner satisfaction. Likewise, user satisfaction is positively associated with system quality. Moreover, the e-learning system success is driven by both system use and learner satisfaction. These results are useful for Moroccan University policymakers in order to develop best practices to ensure a successful e-learning implementation.

Published: April 2022

Argumentation is a scientific literacy practice focused on developing scientific thinking skills associated with problem-solving. As computing has become an integral part of our world, computational thinking skills are requisite for successful problem-solving. The significant effect of computational thinking applications on the efficacy of scientific literacy practices is increasingly acknowledged. In this article, we propose a framework that conceptualizes the constructivist argumentation as a context for problem-solving by applying five computational thinking dimensions, viz. algorithmic design, decomposition, abstraction, evaluation, and generalization. The framework emphasizes two aspects, students’ problem-solving capability and quality of argumentation. Drawing from the literature on scientific argumentation and problem-solving, we argue that the application of computational thinking dimensions in science learning is currently overlooked in the instructional environment. To nurture higher order thinking skills and to engage effective problem-solvers, our framework incorporates four Computational Thinking-Argumentation design principles to support instructional innovation in the teaching and learning of science at the secondary school level, viz. 1) developing problem-solving competencies and building capability in solving uncertainties throughout scientific inquiry; 2) developing creative thinking and cooperativity through negotiation and evaluation; 3) developing algorithmic thinking in talking and writing; 4) developing critical thinking in the processes of abstraction and generalization.

While the COVID-19 crisis has sparked renewed interest in online learning research, there are only a few well-documented studies on students' perceptions of Internet access in online (remote) learning. As a result, we adopted a quantitative approach to investigate students' perceptions of Internet access for online (remote) learning in Indonesian higher education institutions during the COVID-19 pandemic. The data were analysed using descriptive statistics and content analysis. The findings indicate that students in Indonesian higher education institutions negatively perceive their experience with online (remote) learning during the COVID-19 pandemic. They are dissatisfied with the poor performance of the Internet as well as the high cost of Internet access. They also have concerns and impediments regarding online (remote) learning. Finally, the current study's implications are discussed, along with some recommendations for future research.

Study of risk factors in patients with postpartum hemorrhage- an observational study
Authors: Uthpala V. , Gracelyn J. Leila
Published: April 2022

Background: In both developed and developing countries, postpartum haemorrhage (PPH) can occur in 1-5% of deliveries, and it is still the leading cause of maternal morbidity and mortality. Clinicians must be aware of PPH risk factors and should consider them when counselling women about where to birth. The goal of this study was to assess risk factors in patients with postpartum hemorrhage.Methods: This study comprised 50 pregnant patients with PPH. Their maternal age, parity status, GA, and mode of delivery were recorded. Other associated co-morbidities with PPH such as anaemia, H/O LSCS, hypertensive status, abruptio placentae, premature rupture of membranes, and prolonged labour were also recorded. The morbidity rate and intervention employed were also recorded.Results: In the present study, significant risk factors for PPH were 20-24 years of age, primipara, severe anaemia (Hb<7 gm%), previous LSCS, hypertensive disorders of pregnancy, premature rupture of membranes, abruptio placentae and prolonged labor.Conclusions: Monitoring these identified risk factors could enable extra vigilance during labor, and preparedness for managing PPH in all women giving birth
A causal model of the continuum of care for maternal, newborn, and child health in Myanmar: a structural equation modeling approach
Authors: Myint Kyaw S. , Mya Khin S.
Published: April 2022

Background: Incredible drop in global maternal mortality ratio (MMR) and neonatal mortality rate (NMR) is still far from sustainable development goals (SDGs) targets. Applying the continuum of care (CoC) concept reduces mother and newborn deaths. We determined the influencing factors of the continuity of maternal, newborn, and child health care (MNCH) services from pregnancy to child immunization with structural equation modeling (SEM) to continuously improve health outcomes and MNCH service utilization.Methods: We included 1,669 pair samples of mothers and their children under 24 months from (2015-2016) Myanmar demographic health survey (MDHS) data. We used STATA software (version 14) for all analyses. We evaluated the relationships between four latent independent constructs-characteristics of the individual, household, socio-economic, and child and four latent dependent constructs of CoC components- utilization of antenatal care (ANC), delivery, postnatal care (PNC), and vaccination programs using SEM approach.Results: Adequate utilization of ANC, delivery, PNC, and child immunization along the MNCH pathway were 19.7%, 44.8%, 21.8%, and 30.6%, respectively. SEM analysis shows that socio-economic status influences all CoC care components. Moreover, the receiving ANC favors the utilization of subsequent components of delivery, PNC, and vaccination. However, receiving delivery care favors only PNC utilization but not childhood vaccination. In addition, PNC utilization does not affect childhood vaccination.Conclusions: The quality and coverage of ANC is the most crucial factor in establishing the care continuum of MNCH services in Myanmar. The overall socio-economic development of the nation will alleviate the inequity in health access.

Published: April 2022

In a given time, 55% of smokers and 50% of smokeless tobacco users think of quitting tobacco. However, only 3-5% successfully quit without professional support. This study aims to assess the quit status and challenges of tobacco users enrolled in tobacco cessation clinic at a regional cancer center. Totally, 171 tobacco users above 18 years were enrolled in the TCC between January 2015 and December 2015. All the users were contacted by a psychologist via telephone after 6 months from their first visit for gauging the status of tobacco use, associated challenges for quitting and reasons for not quitting. Nicotine dependence was assessed using the Fagerstrom scale for nicotine dependence for smokers and smokeless tobacco users, separately. Readiness to quit tobacco scale was used to assess the motivational stages of readiness to change. Based on level of nicotine dependence and motivational stage, cessation interventions were provided. On follow-up, 91 (53.2%) were successfully contacted, 72 (42.1%) could not be contacted and 8 (4.6%) had expired. Twenty-six (28.5%) tobacco users had quit and 15 (16.4%) were able to remain abstinent for less than 6 months. Only 5 (12.1%) reported physical challenges and 13 (31.7%) reported psychological challenges while reducing tobacco or quitting. Tobacco cessation provided by trained professionals in a cancer setting has been found to be highly effective in quitting. Close follow-up at regular intervals is mandated to help tobacco users manage cravings and withdrawal symptoms, to assist in achieving quit status.

On the telecommunications front, 5G is the fifth-generation technology standard for broadband cellular networks, which is a replacement for the 4G networks used by most current phones. Hundreds of businesses, organizations, and governments suffer from cyberattacks that compromise sensitive information in which 5G is one of them. Those breaches of the data would not have occurred if there is a way to detect strange behaviors in a 5G network, and this is what this paper presenting. Network Anomaly Detection (NAD) in 5G is a way to observe the network constantly to detect any unusual behavior. However, it is not that straightforward and rather a complex process due to huge, continuous, and stochastic network traffic patterns. In the literature, several approaches and methods have been employed for anomaly detection as well as prediction. This paper illustrates state-of-the-art method to proposed achieve the NAD. For instance, pattern based, machine learning based, ensemble learning based, user intention based, and some integrated methods have been surveyed and analyzed. KNN and K-prototype algorithm were tested together on the dataset and compared with integrated approach. The integrated approach outperformed with respect to the KNN and K-prototype methods. As a conclusion, forecasting of analyst detection of cyber events is presented as a final method for future anomaly prediction.
Influence of Strut Geometry on the Size Effect of FRP Reinforced Simply Supported Deep Beams: A Theoretical Analysis
Authors: Zinkaah Othman Hameed , Sultan Hussein Kareem , Al-Rifaie Ali , Alridha Zainab
Published: April 2022

The reduction in the shear strength accompanied to the increasing in the section depth is characterised as size effect, assuming that all parameters are kept constant. Such behaviour is controlled by many factors. The geometry of the element formed between the load and support points is one of those factors that need to be highlighted. Owing to that, this study aims to assess the impact of the strut geometry on the size effect from the strut and tie method (STM) point of view. As the strut geometry is represented by bearing plates and concrete cover, the current study has focused on those two parameters. Accordingly, two groups of specimens have been examined analytically using STM of the American, European and Canadian codes. In each group, three depths were used of 500, 100, and 1500 mm. The only differences between those two groups are dimensions of bearing plates (loading and supporting) and concrete cover. In the first group, the dimensions of bearing plates and concrete cover have been kept constant with 250 mm and 60 mm, respectively regardless of the section depth. In the second group, those two parameters have been proportioned with the section height to be 15% and 8% of section height, respectively. Furthermore, an experimental database of 25 deep beams reinforced with polymer bars has been compiled from the literature to evaluate the ability of the STM to consider the size effect. The results showed that STM does not consider the size effect. Additionally, the collected data confirmed that the STM of American and European codes overestimated the shear capacity, while the STM of Canadian code gave a conservative prediction, highlighting the need of suitable models for shear strength prediction of FRP reinforced deep elements.

Published: April 2022

To determine the shelf life of a product, an appropriate method is needed. This research aims to predict the shelf life of instant chocolate by using accelerated shelf life test (ASLT) with the Arrhenius equation. Instant chocolate was stored at 30℃, 40℃, and 50℃ in polypropylene plastic packaging for 42 days under vacuum conditions. Changes in water content, free fatty acids, flavour, clumping and total microbial number were detected. Results showed that an increase in temperature and shelf life duration can increase the water content and free fatty acid levels and reduce the score on the flavour reception of instant chocolate. Shelf life was estimated based on free fatty acid levels and first-order reactions. The shelf life of instant chocolate stored at 30℃, 40℃, and 50℃ is 281.58, 240.99 and 113 days, respectively.

Authors: Abidalla Wisam Abdulabbas , Naser Ahmed Sami , Nasir Mohsin J.
Published: April 2022

This research aims to find a suitable transportation rate formula for bed load. Laboratory experiments were conducted in a flume for monitoring and measuring the transportation of sediment particles (bed load) which move by jumping, rolling, or sliding within the flume. This study included two parts. The first part is experimenting using a flume and tracking the particles' movement by analysing the images taken by the camera. The measurements that have been taken are the amount of accumulated bed load particles at the end of the flume, which are distributed along a certain distance during a specific time, thus obtaining measuring data about the amount of accumulated bed load and values of moving distance and the required time for accumulating the particles at the flume end. The accumulated height of bed load is also measured. These experiments were conducted at different low-flow velocities. The second part includes the expression of a formula for bed load transportation rate, which is the product of multiplying the accumulated height of bed load by the velocity of bed load particles with distance at a certain time that was devised in the first part. Through the proposed method of obtaining the measurements in the first part Analysis of bed load particle velocity was done by using (π-theorem) from the results of experiments (Cv, V, ρ, ρS, µ, ds, L). To derive the formula of accumulated bed load height at flume end along a certain distance using Rayleigh’s method and using the results of the experiment (δ, V, g, ds). Finally, there can be found an expression of the bed load transportation rate formula. Checking was made for this formula, which was compared with other researchers' equations using statically measured. It was found that the derived formula was acceptable to calculate the transportation rate of bed load.

In order to improve the tracking performance and robustness characteristics of ADRC, minor modification has been made in its structure, which is represented by adding feed forward control signal to reference angular acceleration. The numerical simulations via MATLAB software environment have been conducted with various model uncertainties and external disturbances to assess the performance of modified control scheme. The proposed controller showed improvement in trajectory tracking error, rejection of exerted disturbances, and robustness against parameter uncertainties.
IMGTXT: Image to Text Encryption Based on Encoding Pixel Contrasts
Authors: Jirjees Seerwan Waleed , Alkhalid Farah Flayyeh
Published: April 2022

Nowadays, when data is exchanged over the internet, the security of data is critical in every element of life. Unauthorized network access is possible due to information transmission. As image usage increased in most communications, image privacy became an issue. Image encryption is one of the methods used to protect images online. In this paper, we proposed a new approach called IMGTXT that converts the image to text by coding the pixel values depending on locations then encrypts them by any trust encryption text algorithm, so that this method provides resistance to a variety of attacks such as histogram attacks and brute force attack. The state of the art of this research is the image is represented as a text and there is no relationship between the cipher-image and the plain image. Although this results in a large data volume. The proposed technique builds and testes on various images with different sizes, the recorded results demonstrate the technique’s efficacy and robustness to resist the brute force attack and statistical cryptanalysis of original and encrypted images.
Los Principios de París y las instituciones nacionales de derechos humanos en América Latina
Authors: López Escarcena Sebastián
Published: April 2022

Los Principios de París proveen los parámetros a través los cuales se miden las instituciones nacionales de derechos humanos, en el importante proceso de acreditación que administra la red internacional que hoy las agrupa. Por su origen, dichos principios privilegian como modelo institucional a la comisión de derechos humanos sobre el ombudsman y el instituto de derechos humanos, y se centran en la creación de estas instituciones, más que en su posterior funcionamiento. Estos dos aspectos constituyen una limitante de dichos principios. Aun cuando el primero de estos problemas ha sido superado en la práctica, el segundo se mantiene plenamente vigente, por lo que sería conveniente identificar criterios de eficiencia que vayan más allá del diseño institucional y orienten a las instituciones nacionales de derechos humanos en el cumplimiento efectivo de sus funciones. En el caso de América Latina, es esencial velar por la integración de estas instituciones para el logro de dicho objetivo. Solo contando con un personal adecuado pueden estas persuadir e influir no solo a los órganos estatales, sino también a la sociedad civil, promoviendo y protegiendo así los derechos humanos de todos.

Published: April 2022

The use of remotely piloted aircraft systems (RPAS) is already a reality in applications such as geographic mapping, surveillance, digital marketing, delivery, agriculture, infrastructure inspection, and others. Most of these aircraft are purely electric, being the only source of energy, packs of ion-lithium or lithium polymer batteries. These battery packs are conceived by the association of a different number of cells, usually ranging from three cells (3S) to twelve cells (12S). However, universal battery chargers for this range are not consolidated yet due to the recent emergence of the use of RPAS for different applications. To overcome this drawback, this paper introduces a topology to charge a wide range of low voltage battery packs (3S-12S) for RPAS. The circuit is composed of two power converters, one of them is a DCM SEPIC PFC rectifi er and another is a dc-dc Buck converter. The system is design for 400 W of rated power and the proposed solution is suggested to charge battery packs from 3S to 12S.

Relacje pomiędzy turystyką a przestrzenią mają charakter interakcji zakładającej wzajemny charakter oddziaływania. Masowy rozwój turystyki przyczynia się do zintensyfikowania jej oddziaływania na przestrzeń, postrzeganego głównie przez pryzmat zmian degradacyjnych, powodujących zaburzenie ładu przestrzennego. Równolegle wyjątkowo słabo identyfikowane jest znaczenie przestrzeni, a szczególnie ładu przestrzennego jako jednej z determinant rozwoju turystyki. Na płaszczyźnie teoretycznej ta relacja wydaje się oczywista, ale po uwzględnieniu racji praktycznych staje się co najmniej dyskusyjna.

Актуальность. В настоящее время нефтегазодобывающей промышленности России приходится сталкиваться с определенными трудностями, влияющими на эффективность добычи углеводородов и уровень разработанности месторождений нефти и газа соответственно. Особый интерес добывающих предприятий и научного сообщества представляют трудноизвлекаемые запасы, поскольку их объем велик и с каждым годом повсеместно увеличивается. На данный момент, по оценке Минэнерго РФ, доля трудноизвлекаемых запасов составляет более 65 % от общего объема доказанных запасов в стране. Время «легкой нефти» заканчивается. На данный момент в общероссийской добыче доля трудноизвлекаемых запасов составляет около 10 %. По этой причине существует необходимость разработки и внедрения новых технологий воздействия на пласты, содержащие такую нефть, и усовершенствования существующих методик. Цель: разработать эффективную технологию повышения коэффициента нефтеизвлечения залежи массивного типа, сложенной неоднородным терригенным коллектором с наличием газонефтяного и водонефтяного контактов.Объектом является залежь массивного типа, сложенная неоднородным терригенным коллектором с наличием газонефтяного и водонефтяного контактов. Методы: анализ современной научно-технической литературы и производственных отчетов по результатам применения различных технико-технологических решений по повышению дебита скважин и снижению обводненности продукции; описание новой технологии разработки неоднородной залежи массивного типа с газонефтяным и водонефтяным контактами. Результаты. Предложена технология разработки неоднородной залежи массивного типа с газонефтяным и водонефтяным контактами. Технология позволит повысить эффективность добычи нефти за счет увеличения зоны охвата залежи в нефтенасыщенной части пласта. Новизна заключается в системе расстановки добывающих скважин с горизонтальным окончанием и наклонными ответвлениями относительно уровней водонефтяного и газонефтяного контактов в залежи массивного типа, а также направленности и очередности бурения наклонных ответвлений от зон указанных контактов.

The Bank Indonesia Scholarship is a scholarship provided by Bank Indonesia for students at various universities, one of which is UIN Maulana Malik Ibrahim Malang. In the scholarship selection process, there are several criteria that affect the graduation of prospective scholarship recipients. However, often the process is not transparently. So a calculation method is needed, one of which is using Fuzzy Multi Criteria Decision Making (FMCDM). With FMCDM it can help to get an accurate and optimal decision on scholarship recipients. The FMCDM process begins with collecting information related to scholarships, scholarship applicants, and a set of criteria that will be used for consideration of scholarship acceptance. The set of criteria consists of 11 criteria, namely, Academic Achievement Index (GPA), international level achievement, national level achievement, provincial level achievement, district/city level achievement, father's occupation, mother's income, number of family dependents, house area, land and building tax, as well as electricity bills. The next step is to evaluate the fuzzy set by aggregating the weight of the criteria and the degree of compatibility of each alternative with the criteria. The aggregation result is called the fuzzy fit index which consists of 3 values, namely, the y value which represents the lower limit of the aggregation result, the q value which represents the middle limit, and the z value which represents the upper limit value. The three values are ranked using a ranking method for fuzzy numbers with a degree of optimism. So that the total integral value for each alternative will be obtained, which will be the decision in accepting the scholarship. From the results of the FMCDM, there is a ranking of decision alternatives from the highest priority to the lowest in determining scholarship acceptance.
The Effects of COVID-19 on Food Equity and Nutrition Security in sub-Saharan Africa: Lessons from a Multi-Phase Assessment
Authors: Salm Leah , Nisbett Nick , Lulache Alexandra
Published: April 2022

The COVID-19 pandemic in sub-Saharan Africa has elicited reactions that are also seen worldwide: widespread and indefinite health effects, and deep reverberations on almost all parts of daily life, from livelihoods, to freedom of movement and the availability of foods and services. As was seen in previous health crises such as that of HIV or Ebola, the effects of the pandemic are mediated by pre-existing power structures, vulnerabilities, and systems of support, which lead to differentiated outcomes for people and communities, often to the detriment of the poorest groups. This study examines the impact of COVID-19 on commercialising farmers across sub-Saharan Africa, with a deeper focus on Nigeria and Malawi, from a food equity perspective.

Syphilis is a primarily sexually transmitted disease that has gained importance again due to the increasing number of cases worldwide. This study aimed to investigate at how scientific output on Syphilis has changed since 1970 globally. This bibliometric study was performed in the Clarivate Analytics’ Web of Science (Wos) database by searching the ‘Treponema pallidum’ or ‘Treponema pallidum subsp. pallidum’ or ‘Syphilis’ keywords. The research only included documents categorized as 'journal article' in the Wos database; reviews, letters, and editorials were excluded. Analysis was performed on articles published between 1970-2021. We compared the total global output relating to syphilis. We then looked at the contributions of countries, organizations, authors to the global output. Based on the search method utilized in this study, the findings revealed that 6747 articles on syphilis were indexed in the Wos database between 1970 and 2021. This articles were 96790 times cited (14.35 times average per item), the H-Index was 101. 57.329% of them were published after 2000s. Since 2015, the number of articles has never dropped below 200. The top cited articles were published in recent 20 years. The USA (35.230%) published most of the articles on syphilis. The People's Republic of China, England, the United Socialist Soviet Republic, Brazil, France, Australia, Canada, and Germany were also 10 ranked countries. The articles were from 181 countries globally. Publications and organizations providing financial support were from developed countries. However, researchers in developing countries should be supported to reduce the spread and mortality/morbidity of syphilis.
KEFEVÎ-ZÂDE MEHMED ÂDİL, MECMUASI VE ŞİİRLERİ
Authors: DONUK Suat
Published: April 2022

Klasik Türk edebiyatı şair ve yazarların yaşam bilgilerini ihtiva eden eserler bakımından zengindir. Ancak geniş bir coğrafyaya hükmeden Osmanlı Devleti’nin şairlerinden bazıları devlet merkezine uzak olma, divan sahibi olmama, biyografi yazarlarının erişim sahasına girememe, sınırlı şairlik yeteneğine sahip olma gibi nedenlerle kaynak eserlerde kendilerine yer bulamamıştır. Bu tür şairlerin şiirleri mecmua ve cönkler yardımıyla günümüze kadar gelmiştir. Son zamanlarda mecmua ve cönkler üzerine yapılan araştırmalar neticesinde kaynaklarda ismi zikredilmeyen çok sayıda şair edebiyatımıza kazandırılmıştır. Çeşitli seçme mensur metin ve manzumenin bulunduğu bir mecmuaya şiirlerini kaydeden Kefevîzâde Mehmed Âdil bunlardan biridir. Manzumelerindeki anlatımlara ve onun istinsah ettiği yazma eserlerdeki kayıtlara göre Mehmed Âdil, Sultan I. Abdülhamid döneminde yaşamıştır. 1187/1773-74 - 1222/1807-8 tarihleri arasında Ermenek, Baalbek, Şorba, Payas ve Şile gibi yerlerde kadılık yapmıştır. Âdil mahlasıyla şiirler yazmıştır. Döneminin önemli devlet adamlarına kasideler sunmuştur. Mehmed Âdil’in mecmuasında beşi müfred, biri mesnevi, üçü gazel, üçü kıt‘a, dördü kaside olmak üzere 16 manzumesi kayıtlıdır. Manzumelerden ikisi Fars dilinde yazılmıştır. Şiirlerde devlet büyüklerine övgü, peygamber sevgisi, sevgiliye duyulan istek, dünyanın geçiciliği, konuşmanın önemi gibi farklı temalar işlenmiştir. Kimi manzumelerde sade ve süssüz bir dil ve anlatım sergilenirken kasidelerde ağır ve tumturaklı bir üslup tercih edilmiştir. Mehmed Âdil’in manzumeleri klasik Türk edebiyatının yerleşik kaidelerine uygundur. Ancak onun bazı beyitleri klasik Türk şiiri metafor ve mazmunlarının inceliğinden ve şiirsel derinliğinden uzaktır. Bu makalede Kefevîzâde Mehmed Âdil’e ait mecmua tanıtılmış; nüsha kayıtları, manzume ve mühürlerden elde edilen yaşam bilgileri sunulmuş; şu an için tespit edilebilen şiirlerinin çeviri yazılı metni ilim âlemiyle paylaşılmıştır.
