Authors: Güngör Kobat Sabiha , Gül Fatih Cem , Kaya Mehmet Kaan
Published: February 2024

Aims: To evaluate the effect of strabismus surgery on psychosocial and functional quality of life.
Methods: 50 adult strabismus patients who presented to our outpatient clinic with the complaint of strabismus in one eye were included in the study. Routine ophthalmologic examinations and strabismus controls were performed. With the diagnosis of monocular fixed eso/exotropia, unilateral horizontal muscle retraction and resection surgery were planned, and preoperative adult strabismus score (AS-20), Rosenberg self-esteem, body perception, and social appearance anxiety questionnaires were applied. A postoperative PD of 10 or less was considered success, and the questionnaires were repeated at the 2nd postoperative month.
Results: The mean age of the patients was 21.54±3.95 (16-32) years. Twenty-two of the patients were female, and 28 were male. Pre-operative and post-operative strabismus AS-20 score, Rosenberg self-esteem, body perception, and social appearance anxiety scales showed statistically significant differences (p<0.05, p<0.001, p<0.001, p<0.001, p<0.001).
Conclusion: Strabismus is an important disease that can cause difficulties in social life both in childhood and adulthood. The aim of strabismus surgery is to restore normal facial appearance as well as functional correction. Our study results showed that successful strabismus surgery can improve the psychosocial and functional quality of life.

Authors: Şensoy Eyüpcan , Teke Mehmet Yasin , Çıtırık Mehmet
Published: February 2024

Myelinated retinal nerve fiber (MRNF) is a developmental anomaly that is often detected during routine ophthalmological examination, but can be an ocular finding in a wide variety of diseases. An important example of this group is the Straatsma Syndrome. Straatsma Syndrome is an entity that presents with the triad of myopia, amblyopia, and MRNF. When this triad is accompanied by hyperopia instead of myopia, it is referred to as the Reverse Straatsma Syndrome. Here, we present a case of Reverse Straatsma Syndrome accompanied by lamellar congenital cataracts.

Authors: Soy Furkan , Çakır Ayşe Didem , Pehlivan Ozan , Aydemir Mehmet , Dündar Tevfik
Published: February 2024

Aims: Vitamin D deficiency is a prevalent health issue globally. Outpatient clinics frequently encounter complaints related to vitamin D deficiency in adults. This study aims to determine the prevalence of 25(OH) vitamin D deficiency in patients over 18 years old and to investigate potential differences in 25-OH D levels based on age, gender, and seasonal factors.
Methods: This cross-sectional study included 12,740 patients (9,550 females, 3,190 males) with a mean age of 45 years (ranging from 18 to 99 years) attending the Orthopaedics and Traumatology outpatient clinic and Internal Medicine outpatient clinic. The serum 25(OH) Vit D was measured using the ELISA method. The patients were divided into three groups: 1) patients with vitamin D deficiency (<20 ng/ml), 2) patients with insufficient vitamin D levels (21-29 ng/ml), and 3) patients with normal vitamin D values (>30 ng/ml). Binary logistic regression analysis was used to analyse the risk factors for vitamin D deficiency.
Results: The study found that 68.6% of the participants had a vitamin D deficiency, while 21.2% had a vitamin D insufficiency. Binary logistic regression analysis revealed that low levels of 25(OH) Vitamin D were associated with age, gender, and the spring season.
Conclusion: This study suggests that patients with related complaints or findings at outpatient clinic visits should be evaluated for vitamin D deficiency or insufficiency. If diagnosed, dietary support and vitamin D supplementation may be appropriate for those in high-risk groups.

Authors: Özdemir Adnan
Published: February 2024

Aims: The aim of our study was to evaluate the incidence of pneumatized structures in the paranasal region and the presence of osteomas.
Methods: Paranasal CT images obtained with Multislice (Philips) 64-slice computed tomography (CT) at Kırıkkale University Hospital in 2023 were retrospectively analyzed. Pneumatized variations and the presence of osteoma were evaluated.
Results: The images of 186 patients (93 female and 93 male) with paranasal CT were analyzed. The most common pneumatized variation was middle turbinate bullosa with 40.3%, and the least common was pneumatization of the nasal septum with 2.1%. Anterior clinoid pneumatization was observed in 23.1%, posterior clinoid pneumatization in 2.2%, pneumatization of the uncinate process in 4.9%, and crista galli pneumatization in 4.3%. The frequency of osteomas in the paranasal region was 3.2% (n=6).
Conclusion: Our study will provide a better understanding of paranasal anatomy by providing information about the frequency of pneumatized paranasal variations and the presence of osteomas. This will guide the surgeon in surgical planning and at the time of surgery.

Published: February 2024

Aims: In this study, it is aimed to investigate the density of high placed jugular bulbus (HPJB), which is useful to know from a clinical and surgical perspective.
Methods: Between the dates of May and November 2023, temporal computed tomography (CT) scans which took place in the CT (General Electric) were evaluated retrospectively.742 cases and 1484 ears were included in the study. Jugular bulbus (JB) was evaluated based on the internal acoustic canal (IAC).
Results: The age range of 742 cases was 18-72. Of the cases, 796 were women and 688 were men. HPJB was detected in 44 (3%) of 1484 ears. Of the 44 ears in which HPJB was detected, 26 (59%) were located on the right and 18 (41%) were located on the left. HPJB were monitored more frequently on the right side.
Conclusion: HPJB can cause various otological symptoms, especially tinnitus. Additionally, not knowing the existence of HPJB increases morbidity rates, especially in lateral skull base surgery. In various otological findings of unknown etiology and preoperatively before lateral skull base surgery, the jugular bulb should be evaluated with temporal CT.

The Relationship Between Atherosclerotic Risk Factors and Female Gender
Authors: Özkan Asibe , Karagöz Esra
Published: February 2024

Introduction: Identification and control of cardiovascular risk factors form the basis of strategies for protecting cardiovascular health. However, according to the results of many studies, women are less aware of their own risk factors and participate less in screening programs than men. This study was conducted to determine the risk of experiencing atherosclerotic events and risk-related factors in women aged 40-79 years.

Patients and Methods: This retrospective, cross-sectional analysis was conducted by the primary physician of the laboratory values used in atherosclerotic cardiovascular disease (ASCVD) risk assessment, who applied to the consultant outpatient clinics (pulmonary diseases, infectious diseases, nephrology, internal medicine outpatient clinics) in a training and research hospital between September and November 2021. The data of 131 female patients between the ages of 40-79 were analyzed.

Results: The average age of the 131 women included in the study was 51.6 years. It was observed that women predominantly had three or four risk factors. The five most common risk factors identified were as follows: a total cholesterol level above 170 mg/dL (86.3%), menopause (65.6%), HDL cholesterol below 50 mg/dL (64.1%), systolic blood pressure above 130 mmHg (56.4%), and smoking (32.1%). In the study, when investigating the relationship between the ASVCD risk calculator, atherosclerosis risk factors, and the menopausal period, statistically significant associations were observed between age, systolic blood pressure, total cholesterol, HDL, LDL, 10-year risk ratio, optimal risk ratio, and lifetime risk ratio.

Conclusion: The study determined that the average lifelong expected ASCVD risk among the women participating in the study, in terms of cardiovascular diseases, was 39.87 ± 8.81%. This finding highlights the significance of cardiovascular diseases and underscores the importance of conducting comprehensive risk assessments at the individual level to prevent them.
The Impact of Serum Interleukin-4, Interleukin-10, Interleukin-17a, and Interleukin-22 Levels on the Development of Sporadic Ascending Aortic Aneurysms
Authors: Batgerel Ulaankhuu , Özgen Ayça , Yurdagül Gaye Erten
Published: February 2024

Introduction: Aortic aneurysms are chronic diseases associated with inflammatory/immunological mechanisms. Interleukins (ILs) with pro-inflammatory and anti-inflammatory activities are shown to be related to the development of aortic damage. In this context, this study aims to evaluate the serum IL-4, IL-10, IL-17A, and IL-22 in patients with sporadic thoracic ascending aortic aneurysms.

Patients and Methods: The population of this prospective study consisted of all consecutive patients with sporadic ascending aortic aneurysms who underwent thoracic aortic aneurysm repair between November 2019 and September 2022. In the end, 29 patients (the patient group) and 19 healthy voluntary participants without aortic pathology (the control group) were included in the study. The study’s primary outcome was the differences in serum IL levels between the groups.

Results: The patient group was significantly older than the control group (p= 0.042). Significantly higher neutrophil-to-lymphocyte ratio (NLR) values were detected in the patient group (p= 0.031). The median IL10 (p= 0.001), IL-17A (p< 0.001), and IL-4 (p< 0.001) levels were significantly lower in the patient group than in the control group. There were no significant correlations between serum IL levels and the aneurysm diameter (p> 0.05). On the other hand, there were moderate correlations between IL-10 and IL-17A (r= 0.409, p= 0.038), IL-10 and IL-22 (r= 0.464, p= 0.017), and IL-17A and IL-4 (r= 0.496, p= 0.006). NLR ≥1.95 was found to be an independent risk factor for sporadic ascending aortic aneurysms [Odds Ratio (OR)= 4.53, 95% confidence interval (CI)= 1.12-21.17, p= 0.040].

Conclusion: IL-10, IL-17A, and IL-4 were significantly lower in patients with sporadic ascending aortic aneurysms larger than 55 mm. NLR was an independent risk factor for sporadic ascending aortic aneurysms. The diameter of the aneurysm was not correlated with ILs. There were positive correlations between IL-10, IL-17A, and IL-4 levels.

Authors: Durmaz Duygu , Gündöner Sedat , Tekümit Hayrettin , Berki Kamil Turan
Published: February 2024

Introduction: The aim of this study was to assess the efficacy of isolated coronary artery bypass grafting (CABG) on preoperatively existing mild-to-moderate chronic ischemic mitral regurgitation.

Patients and Methods: A retrospective analysis was conducted on 30 patients who had coronary artery disease and chronic ischemic mitral regurgitation, and underwent isolated CABG at the Department of Cardiovascular Surgery, Kocaeli University, between January 2012 and February 2014. Preoperative demographic and clinical characteristics, as well as postoperative outcomes, were evaluated. The degree of IMR, left ventricular ejection fraction (LVEF), left ventricular end-systolic dimension (LVESD), left ventricular end-diastolic dimension (LVEDD), and left atrial dimension (LAD) were assessed preoperatively, and at the postoperative 12th month.

Results: There was no mortality during the early postoperative period. There were statistically similar measurements for LVEF, LVESD, LVEDD, and LAD between preoperative and postoperative periods (p> 0.05). However, a decrease in the degree of IMR was detected during the specified periods (p< 0.05).

Conclusion: Isolated CABG can be safely performed in patients with mild/moderate chronic ischemic mitral regurgitation. The efficacy of isolated CABG was demonstrated to improve the degree of mitral regurgitation in selected patients based on echocardiographic measurements.

Published: February 2024

Introduction: Although most of the scoring systems are used for long-term mortality assessment in STelevation myocardial infarction (STEMI), there is still lack of data comparing model performances. In this study, it was aimed to compare five scoring systems for predicting long-term mortality in patients presented with STEMI.

Patients and Methods: This is a retrospective observational study consisting of 1689 consecutive STEMI patients who underwent PCI between 2009 and 2013. Patient data was obtained from the electronic data base of the hospital. Each patients’ mortality risk was assessed with five different risk scores and recorded.

Results: A total of 1689 patients with STEMI were included into the study. Median follow-up time was one year. Risk scores were calculated for each patient. Although similar statistical significance was presented among all scores, modified age, creatinine clearance, and ejection fraction score (mACEF) were demonstrated to be more significant than relevant scoring systems in clinical respect.

Conclusion: Among five scores, the mACEF score was demonstrated to be the most significant model in clinical respect for the prediction of mortality.

This research investigates the key factors contributing to the
success of Nakshi Kantha businesses in Jamalpur, Bangladesh, a traditional
handcrafted embroidery technique with profound cultural and economic
significance. The study explores seven independent variables, including
Financial Resources, Promotional Efforts, Institutional Support, Market
Demand, International Trade Prospects, Entrepreneurial Collaboration, and
Workforce Competency, in relation to Business Success in this context.
Employing linear regression analysis, the study uncovers that Financial
Resources, Promotional Efforts, International Trade Prospects, Market
Demand, and Workforce Competency significantly influence the success of
Nakshi Kantha businesses. In contrast, Government and banking support
and Entrepreneurial Collaboration exhibit weaker associations with
business success. These findings emphasize several crucial factors for
Nakshi Kantha entrepreneurs and policymakers. First, securing adequate
financial resources is paramount to sustain and grow these businesses.
Second, investing in marketing and promotional activities is essential to
enhance brand visibility and stimulate market demand. Third, nurturing a
skilled and competent workforce is vital for maintaining product quality and
meeting market demands. Additionally, exploring international trade
prospects can open new avenues for expansion. Moreover, promoting
collaboration among Nakshi Kantha business owners and facilitating
government and banking support are essential for the industry's sustainable
development and economic prosperity in the region. This research provides
valuable insights for Nakshi Kantha stakeholders, offering a roadmap to
address challenges and ensure the continued growth and success of this

Published: February 2024

This study investigates the relationship between formal education
and the standard of living in Nigeria by analyzing the impact of government
expenditure on education and school enrolment on the country's GDP per
capita as a proxy for standard of living. Using 30 years of annual time series
data and employing the ordinary least square (OLS) method, the study
evaluates the time series properties of the variables with Augmented DickeyFuller (ADF) and Philip Peron unit root tests, and tests hypotheses using Ftests and t-tests. The findings reveal that school enrolment and government
expenditure on education jointly explain a significant portion (93.33%) of
the variation in GDP per capita, highlighting the vital role of education in
driving economic growth and improving the standard of living in Nigeria.
Specifically, higher enrolment rates in secondary and tertiary education
exhibit positive and significant effects on GDP per capita, indicating that
investments in higher education lead to increased productivity, higher
incomes, and improved economic outcomes and living standards. However,
a notable finding shows that government expenditure on education has a
negative and insignificant effect (-27.45) on GDP per capita, calling for
further exploration into the effectiveness and allocation of education
spending for sustainable economic growth. As a result, several
recommendations are proposed, including prioritizing investment in
secondary and tertiary education to enhance individuals' skills and job
opportunities, improving education quality and access, optimizing
government spending on education, fostering collaboration between the
public and private sectors in education, and combining education initiatives
with poverty alleviation programs to address root causes of poverty and
improve living standards for vulnerable populations, contributing to
Nigeria's long-term economic development and prosperity.
Considerations on the Persons that Can Determine the Manner of the Funeral in the Light of the ECHR Judgment from 23 May 2023 in the Case of Buhuceanu and Others vs. Romania*
Authors:   Lucian Blaga University of Sibiu, Șchiopu Silviu-Dorin
Published: February 2024

Each person owes a death and someone has to take care of the funeral even when the deceased left some instructions. The same happens in the absence of an express option of the deceased. Starting from the current Romanian legislative solution for the latter situation, the present study aims to analyse the impact of the ECHR Judgment from 23 May 2023 in the Case of Buhuceanu and Others v. Romania on the national legal framework that governs the persons who can determine the manner of funeral in the absence of an express option of the deceased. This paper argues the need of legislative intervention in order to secure the same-sex couples’ right to respect for their private and family life by affording them the possibility of legal recognition and protection, including the right to determine the manner of the deceased spouse/partner’s funeral in the absence of an express option of the latter and the right to arrange the funeral, core rights relevant to a couple in a stable and committed relationship.

The exercise of commercial activity requires the fulfillment of specific obligations, starting with the fulfillment of registration formalities in the Trade Register, the exercise of trade within the limits of lawful competition, as well as the protection against unfair practices in the relationship with consumers. Regarding unfair practices, the legislator issued specific rules that aim to balance the operation of the market, by promoting a high level of consumer protection, with the prohibition of those commercial practices that affect the economic interests of consumers. The article analyzes deceptive commercial practices, the relevant regulations, with reference to the specific jurisprudence.
The idea of “Own Space” through “Vignettes” in Sandra Cisneros’ The House on Mango Street
Authors: Sherma Amar Bahadur
Published: February 2024

This paper delves into the theme of "Own Space" in Sandra Cisneros' novel, The House on Mango Street. It scrutinizes how the protagonist, Esperanza, navigates the complex concept of home and belonging in a Hispanic neighborhood in Chicago. Drawing from the theories of spatial belonging, patriarchal constraints, and feminist perspectives, the paper highlights Esperanza's quest to carve out her unique space within the constraints of her environment. The use of vignettes as a literary device is explored, demonstrating how they provide insights into Esperanza's evolving identity and the challenges she faces in defying gender roles and societal spatial practices. In addition, it underscores the importance of space production theory, highlighting the role of vignettes in immersing the reader in Esperanza's coming-of-age journey. Ultimately, it argues that Cisneros' narrative style and Esperanza's experiences reflect the broader context of the Chicana experience, making The House on Mango Street a significant contribution to the discussion of cultural identity, gender, and space.
The effect of oxygen fugacity on the evaporation of boron from aluminoborosilicate melt
Authors: Flemetakis Stamatis , Renggli Christian J. , Pangritz Paul , Berndt Jasper , Klemme Stephan
Published: February 2024

Abstract. We present the results of B2O3 evaporation experiments from Ca- and Mg-bearing aluminoborosilicate melts. Our experiments were conducted at 1245 to 1249 ∘C and 1350 to 1361 ∘C for different run times (60–1020 min), and at oxygen fugacities (logfO2) relative to the fayalite–magnetite–quartz (FMQ) buffer of FMQ−6 to FMQ+1.5, and in air. Our results show that with increasing fO2, evaporation of B from the melt increases by a factor of 5 compared to reducing conditions. Using Gibbs free energy minimization calculations, we suggest two possible evaporation reactions for B2O3 which constrain its speciation in the gas phase to be either 3+ or 4+ (B2O3(g) and BO2(g)). The measured B2O3 contents of the B evaporated residual glasses were used to calculate evaporation rate constants (ki) for B2O3 in oxidizing conditions (air, ki=2.09×10-4 cm min−1 at 1350 ∘C) and reducing conditions (FMQ−4, ki=4.46×10-5 cm min−1 at 1350 ∘C). The absence of diffusion profiles in the experimental glasses suggests that the evaporation rates are slower than B2O3 diffusion rates and therefore the rate-limiting process. Overall, the rate of B evaporation in air is approximately a factor of 5 higher compared to reducing conditions at FMQ−4.
A regional pCO2 climatology of the Baltic Sea from in situ pCO2 observations and a model-based extrapolation approach
Authors: Bittig Henry C. , Jacobs Erik , Neumann Thomas , Rehder Gregor
Published: February 2024

Abstract. Ocean surface pCO2 estimates are of great interest for the calculation of air–sea CO2 fluxes, oceanic uptake of anthropogenic CO2, and eventually the Global Carbon Budget. They are accessible from direct observations, which are discrete in space and time and thus always sparse, or from biogeochemical models, which only approximate reality. Here, a combined method for the extrapolation of pCO2 observations is presented that uses (1) model-based patterns of variability from an empirical orthogonal function (EOF) analysis of variability with (2) observational data to constrain EOF pattern amplitudes in (3) an ensemble approach, which locally adjusts the spatial scale of the mapping to the density of the observations. Thus, data-constrained, gap- and discontinuity-free mapped fields including local error estimates are obtained without the need for or dependence on ancillary data (e.g. satellite sea surface temperature maps). This extrapolation approach is generic in that it can be applied to any oceanic or coastal region covered by a suitable model and observations. It is used here to establish a regional pCO2 climatology of the Baltic Sea (Bittig et al., 2023: https://doi.org/10.1594/PANGAEA.961119), largely based on ICOS-DE ship of opportunity (SOOP) Finnmaid surface pCO2 observations between Lübeck-Travemünde (Germany) and Helsinki (Finland). The climatology can serve as improved input for atmosphere–ocean CO2 flux estimation in this coastal environment.
Development of an evidence-based diagnostic algorithm for infection in patients with transcutaneous osseointegration following amputation

Published: February 2024

Abstract. Introduction: Transcutaneous osseointegration following amputation (TOFA) confers better mobility and quality of life for most patients versus socket prosthesis rehabilitation. Peri-TOFA infection remains the most frequent complication and lacks an evidence-based diagnostic algorithm. This study's objective was to investigate preoperative factors associated with positive intraoperative cultures among patients suspected of having peri-TOFA infection in order to create an evidence-based diagnostic algorithm. Methods: We conducted a retrospective study of 83 surgeries (70 patients) performed to manage suspected lower-extremity peri-TOFA infection at a specialty orthopedic practice and tertiary referral hospital in a major urban center. The diagnosis of infection was defined as positive intraoperative cultures. Preoperative patient history (fevers, subjective pain, increased drainage), physician examination findings (local cellulitis, purulent discharge, implant looseness), and laboratory data (white blood cell count, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and external swab culture) were evaluated for association with subsequent positive intraoperative cultures using regression and area under receiver–operator curve (AUC) modeling. Results: Peri-implant limb pain (highly correlated with infection), ESR >30 (highly correlated against infection), positive preoperative swab (moderately correlated with infection), gross implant motion (moderately correlated against infection), and erythema or cellulitis of the transcutaneous region (mildly correlated with infection) were variables included in the best AUC model, which achieved an 85 % positive predictive value. Other clinical findings and laboratory values (notably CRP and WBC) were non-predictive of infection. Conclusions: This seminal investigation to develop a preoperative diagnostic algorithm for peri-TOFA infection suggests that the clinical examination remains paramount. Further evaluation of a wider spectrum of clinical, laboratory, and imaging data, consistently and routinely collected with prospective data techniques in larger cohorts of patients, is necessary to create a robust predictive algorithm.
Climate change impacts on regional fire weather in heterogeneous landscapes of central Europe
Authors: Miller Julia , Böhnisch Andrea , Ludwig Ralf , Brunner Manuela I.
Published: February 2024

Abstract. Wildfires have reached an unprecedented scale in the Northern Hemisphere. The summers of 2022 and 2023 demonstrated the destructive power of wildfires, especially in North America and southern Europe. Global warming leads to changes in fire danger. Specifically, fire seasons are assumed to become more extreme and will extend to more temperate regions in northern latitudes in the future. However, the extent to which the seasonality and severity of fire danger in regions of central Europe will change in the future remains to be investigated. Multiple studies claim that natural variability and model uncertainty hide the trend of increasing fire danger in multi-model climate simulations for future potentially fire-prone areas. Such a trend might be isolated with single-model initial-condition large ensembles (SMILEs), which help scientists to distinguish the forced response from natural variability. So far, the SMILE framework has only been applied for fire danger estimation on a global scale. To date, only a few dynamically downscaled regional SMILEs exist, although they enhance the spatial representation of climatic patterns on a regional or local scale. In this study, we use a regional SMILE of the Canadian Regional Climate Model version 5 Large Ensemble (CRCM5-LE) over a region in central Europe under the RCP8.5 (Representative Concentration Pathway) scenario from 1980 to 2099 to analyze changes in fire danger in an area that is currently not fire prone. We use the Canadian Forest Fire Weather Index (FWI) as a fire danger indicator. The study area covers four heterogeneous landscapes, namely the Alps, the Alpine Foreland, the lowlands of the South German Escarpment, and the Eastern Mountain Ranges of the Bavarian Forest. We demonstrate that the CRCM5-LE is a dataset suitable for disentangling climate trends from natural variability in a multi-variate fire danger metric. Our results show the strongest increases in the median (50th) and extreme (90th) quantiles of the FWI in the northern parts (South German Escarpment and Eastern Mountain Ranges) of the study area in the summer months of July and August. There, high fire danger becomes the median condition by the end of the century, and levels of high fire danger occur earlier in the fire season. The southern parts (Alps and Alpine Foreland) are less strongly affected by changes in fire danger than the northern parts. However, these regions reach their time of emergence (TOE) in the early 2040s because of very low current fire danger. In the northern parts, the climate change trend exceeds natural variability only in the late 2040s. We find that today's 100-year FWI event will occur every 30 years by 2050 and every 10 years by the end of the century. Our results highlight the potential for severe future fire events in central Europe, which is currently not very fire prone, and demonstrate the need for fire management even in regions with a temperate climate.

Published: February 2024

En América Latina se experimenta un incremento sostenido de la esperanza de vida y un envejecimiento acelerado de la población. En el caso de Chile, que es uno de los países de la región que presenta un aumento progresivo de personas mayores de 60 años–cuestión que se explica por los altos niveles de desarrollo alcanzado y a la mejora en sus indicadores socio sanitarios de las últimas décadas–se evidencia que este segmento de la población presenta altos niveles de dependencia.

إشكالية الإعجاز القرآني (تأسيس للمفهوم)

كان وما زال البحث في مسألة الإعجاز القرآني الشغل الشاغل لكثير من الباحثين والمفكرين، فمنذ أن قُدِّمت فكرة (الصرفة) كإعجاز للقرآن، حتى انبرى الكثير الذين رفضوا هذا الرأي ورأَوه تسطيحا لفكرة الإعجاز، وبدأ الانطلاق باتجاه اللغة، فقالوا بالإعجاز اللغوي، وتضافرت الجهود في هذا الاتجاه، حتى أصبح الأمر مشهورا عند القاصي والداني من المتعلم وغير المتعلم، فما أن يُذكر الإعجاز القرآني إلا وتتبادر إلى الذهن مسألة الإعجاز اللغوي، وأضافوا إلى ذلك أمورا أخرى كوجود الغيبيات وبعض المسائل العلمية، ويشكل هذا البحث فكرة مختلفة عن هذا الاتجاه، فيستعرض بعض ما قيل من الإعجاز، ويبين الإشكالات التي ترد على أقوالهم وتدحض اتجاههم، ويركز على توضيح الجانب الإعجازي بشكل محدد، وقد جاء البحث بعنوان (إشكالية الإعجاز القرآني-تأسيس للمفهوم)، وجاءت فكرة هذا البحث انطلاقا من مفهوم كلمة (القرآن) التي تعني مجموعة من الآيات المحددة وليس المصحف بأكمله، وتم إثبات هذه الفكرة في بحث لنا بعنوان (أثر التسوير في ضبط المفهوم القرآني-مقاربة سياقية. كلمة (القرآن) أنموذجا)، وقد ركّزتُ على تفسير قوله تعالى :( قُل لَّئِنِ ٱجۡتَمَعَتِ ٱلۡإِنسُ وَٱلۡجِنُّ عَلَىٰٓ أَن يَأۡتُواْ بِمِثۡلِ هَٰذَا ٱلۡقُرۡءَانِ لَا يَأۡتُونَ بِمِثۡلِهِۦ وَلَوۡ كَانَ بَعۡضُهُمۡ لِبَعۡض ظَهِيرا) (سورة الإسراء:88)، وأظن البحث سابقا لغيره من البحوث، فهو يوضّح مكان التحدّي في الآية، إذ استعرضنا الآيات التي تعني بكلمة (القرآن) المذكورة في الآية وهذا خلاف ما كان يُذكر من أنه إعجاز لغوي الذي لا يصمد أمام إشكالات كثيرة عرضناها في البحث، وأتمنى أن يكون البحث انعطافة مفيدة لفهم القرآن الكريم وتفسيره، والحمد لله رب العالمين.
