OBJECTIVE

Stereoelectroencephalography (SEEG) is a widely used technique for localizing seizure onset zones prior to resection. However, its use has traditionally been avoided in children under 2 years of age because of concerns regarding pin fixation in the immature skull, intraoperative and postoperative electrode bolt security, and stereotactic registration accuracy. In this retrospective study, the authors describe their experience using SEEG in patients younger than 2 years of age, with a focus on the procedure’s safety, feasibility, and accuracy as well as surgical outcomes.

METHODS

A retrospective review of children under 2 years of age who had undergone SEEG while at Children’s Hospital of Philadelphia between November 2017 and July 2021 was performed. Data on clinical characteristics, surgical procedure, imaging results, electrode accuracy measurements, and postoperative outcomes were examined.

RESULTS

Five patients younger than 2 years of age underwent SEEG during the study period (median age 20 months, range 17–23 months). The mean age at seizure onset was 9 months. Developmental delay was present in all patients, and epilepsy-associated genetic diagnoses included tuberous sclerosis (n = 1), KAT6B (n = 1), and NPRL3 (n = 1). Cortical lesions included tubers from tuberous sclerosis (n = 1), mesial temporal sclerosis (n = 1), and cortical dysplasia (n = 3). The mean number of placed electrodes was 11 (range 6–20 electrodes). Bilateral electrodes were placed in 1 patient. Seizure onset zones were identified in all cases. There were no SEEG-related complications, including skull fracture, electrode misplacement, hemorrhage, infection, cerebrospinal fluid leakage, electrode pullout, neurological deficit, or death. The mean target point error for all electrodes was 1.0 mm. All patients proceeded to resective surgery, with a mean follow-up of 21 months (range 8–53 months). All patients attained a favorable epilepsy outcome, including Engel class IA (n = 2), IC (n = 1), ID (n = 1), and IIA (n = 1).

CONCLUSIONS

SEEG can be safely, accurately, and effectively utilized in children under age 2 with good postoperative outcomes using standard SEEG equipment. With minimal modification, this procedure is feasible in those with immature skulls and guides the epilepsy team’s decision-making for early and optimal treatment of refractory epilepsy through effective localization of seizure onset zones.
From Knowledge-Driven to Learning- Driven -The Importance of Workplace Learning
Authors: Erdei Gábor
Published: October 2022

Workplace learning is not only essential for the operation and development of the knowledge economy, but also an important factor in lifelong learning. Moreover, it is one of the most emphasized areas of adult learning. In recent decades, we have also witnessed the fact that school‐based education and training lose their importance while individual learning becomes the dominant knowledge acquisition process and activity in adulthood. Our qualitative research is based on interviews with 23 IT companies operating in Hungary. This sector was chosen because the IT field belongs to the knowledge‐intensive sector, so workplace learning processes can be well studied. The focus of the research is on the learning processes generated by the knowledge gaps in organizations. How does the need for arise? From what sources and in what ways do those working in the organization obtain the necessary information and knowledge? How will the acquired knowledge affect life in the organization? The results of the research enrich the fields of both lifelong learning and adult learning research, and they also contribute to some extent to knowledge management approach.

Objectives. Alkylated derivatives of polyamines are able to block the growth of cancer cells due to their embedding into the polyamine biosynthesis mechanisms. The study aimed to synthesize lipophilic derivatives of norspermine or triethylenetetramine based on the formation of a C–N bond during the opening of the oxirane ring by primary amines to expand a number of synthetic polyamine derivatives with antitumor activity.Methods. The starting compounds—glycidol alcoholate or epichlorohydrin—were reacted with hexadecyl bromide or sodium hexadecanolate to give glycidyl hexadecyl ether. The key reaction for the preparation of lipophilic polyamines was the amination of lipophilic epoxides with polyamines in the presence of calcium triflate. Acylation of the hydroxyl group formed during the opening of oxirane was carried out by the action of 4-dimethylaminopyridine and acetic anhydride. The introduction of an alkyl substituent in the presence of sodium hydride led to intramolecular cyclization with the formation of an oxoazolidine cycle. The regioselectivity of the oxirane ring opening reaction at the C(1) position of glycerol was confirmed by two-dimensional heteronuclear {1H,13C} nuclear magnetic resonance spectroscopy.Results. An approach to the synthesis of novel lipophilic polyamines based on the catalytic amination of epoxides was developed and tested. Compounds based on norspermine and triethylentetramine containing a hydroxyl group at the C(2) atom of the glycerin backbone were obtained. For norspermine derivatives, the hydroxyl group was modified: an acetyl substituent was introduced and a derivative containing an oxoazolidine cycle was obtained.Conclusions. The obtained lipophilic polyamines can be considered as potential antitumor agents, for which cytotoxicity against various cancer cells will be evaluated in the future.
A Resilient China Amid COVID-19 Pandemic Crisis: Innovative Lessons for Other Countries
Authors: Kayani Farrukh Nawaz
Published: October 2022

The outbreak of the Covid-19 pandemic deteriorated the paradigm of the global economy as the whole world had come to a standstill because of massive destructions being caused by this virus. Although the virus originated from China, but it soon spread across the world with its ability to infect the millions of people. The economic destruction, healthcare devastation, and political unrest caused by the pandemic were met with a critically tailored set of policies being designed by Chinese government. The pandemic resulted in a countrywide lockdown of China which led to the economic and political downfall of the country. Millions of people were infected within a short span of time leading to imposition of healthcare emergency by the government. Interestingly, China did not undergo a period of recession during this pandemic, but instead it underwent a prolonged period of economic stagnation as it did not suffer much like other economies of the world. Months after the pandemic had wreaked havoc, China started to gain stability as its efforts towards diffusing the situation proved successful in containing the virus. China being the first country to be struck with this pandemic naturally provides a foolproof plan for other countries to imitate in their struggle towards disease containment. This article has attempted to highlight the impact of the coronavirus pandemic upon China and how the government managed to control the transmission of this deadly virus to a great extent. Furthermore, what innovative and imitating lessons can be learnt by other countries from a resilient China.
Music-based intervention in Covid-19 hospitalization: a perspective through Consolidated Framework for Implementation Research (CFIR)
Authors: Pesce Alessio
Published: October 2022

COVID-19 patients survive in isolation with stringent measures of infection containment, leading to anxiety, fear, stress, loneliness, and depression. Music is recognized as useful to promote multiple health outcomes, including anxiolytic effects, pain-relieving, and relaxing effects that favour well-being and social interaction in healthcare settings. The Consolidated Framework for Implementation Research (CFIR) allows to implement music in hospital, restricting methodological weaknesses. The importance of exploring the in-patients’ preferences, usages, and feelings for COVID-19 before initiating a music-based intervention is crucial.
DATA ON ANXIETY LEVEL OF DENTAL HOSPITAL UNIVERSITAS SUMATERA UTARA FIXED ORTHODONTICS PATIENTS IN NEW NORMAL
Authors: Risfi
Published: October 2022

The lockdown policy for certain dental care during pandemic COVID-19 could cause mental distress. This prolonged pandemic has frustrated orthodontists and patients before the emergence of vaccination. Since the initiation of COVID-19 mass vaccination in January 2021 by the Indonesian government, the aim of this study is to describe the anxiety level of patients undergoing fixed orthodontics treatment regarding routine care from February to May 2021. The highest anxiety level towards routine care during the COVID-19 pandemic was in moderate level (57.4%) and in severe level (40.7%). Both male and female patients showed moderate level of anxiety against routine care during the COVID-19 pandemic. Most patients who came for routine care are from late adolescence (17 to 25 years old) and with a bachelor degree. Orthodontists have to consider patients’ anxiety level in order to obtain a successful orthodontic treatment due to the previous temporary lockdown of the dental hospital. Since the definite time for the COVID-19 pandemic to end is still unknown, social intervention for patients should be considered in managing the mental distress that emerged. In this current time, the expansion of COVID-19 new variants has also become a dilemma for orthodontists and patients. The vaccination and routine screening for COVID-19 is advisable as the requirement for safe routine orthodontics control. Thus, education for oral health maintenance during orthodontics treatment will be an integral part of preventing the COVID-19 local transmission.
Conceptualizing the Liturgical Music of Evangelical Baptists in Tbilisi: Experimentation and Compilation
Authors:   Ilia State University, Naneishvili Nino
Published: October 2022

This presentation examines the liturgical music practices of the Evangelical Baptist Church in Tbilisi (Georgia). Though predominantly ethnic Georgians, the Baptists are a moderate voice for gender equality, religious pluralism, and minority rights, and are sometimes criticized by conservative or nationalistic Orthodox Georgians as a result. My research has encompassed observation during religious services, in-depth interviews, a comparative approach, complex analysis, and intonational analysis. The liturgical music of the Tbilisi Baptists differs considerably from that of Evangelical Baptist churches in other parts of Georgia or other countries. This comes partially as a result of the ideology of this relatively new religious stream, which, in order to facilitate the adaptation of the inexperienced congregation, allows services to be based on national, traditional features. The liturgy, music, and acts of divine service are based on principles established by Archbishop Malkhaz Songulashvili, including the principles of ecumenical “openness” and the synthesis of traditional Georgian values. The music heard in the Georgian-speaking Evangelical Baptist Church today includes the following: Georgian Orthodox chants; chants composed by the present Georgian Orthodox Patriarch, Ilia II; chants from the Taizé Monastery; other foreign repertoires translated into Georgian; Georgian professional music, and experimental electro-acoustic music. The liturgical music of the Evangelical Baptists in Tbilisi is mixed, experimental, and in the process of compilation, and has not yet reached a finalized form.

The Miraculous Nature of the Qura’n Defies Imitability and hence Translatability
Authors: El Mallah Fuzi
Published: October 2022

The Quran in Arabic is unmatched and irreplaceable due to cross-cultural gaps as well as linguistic differences between the Arabic language, in which the original Quranic text is expressed, and some European languages into which the Quran is translated. It is expected, for these reasons, that there will be a considerable loss and hence possible misunderstanding of the main message of the Quran. Nevertheless, translation of the Quran into languages other than Arabic is consensually appreciated by the majority of Muslim scholars as translations are indispensable for those who want to know about the basic rules of Islam, whether they are Muslims or not. This paper will therefore discuss issues related to some aspects of Qur'an translations by analysing selective translated Qur'anic verses that render the miraculous aspects of Quranic text, particularly those of linguistic and scientific nature. It will review some Quranic verses and compare their different English translations, showing, where possible, the general factors governing the systematic mechanism that helps to understand the miraculous nature of the original Quran. The polysemous nature of Quranic terms, the comprehensiveness, and the constantly used techniques of generalization make Qura’nic text resistant to any deficiency that might be caused by the passage of time. The generality of wording is one of the key elements for being time-resistant, so any new sense that occurs in the future should be included in the translation rather than excluded.

Lizard diets can be influenced by several factors, such as age, physiological aspects, food availability, behaviour and foraging mode. The latter can be an important predictor of the type of prey consumed. This study analysed Ameivula ocellifera and Tropidurus cocorobensis diets, both of which are psammophiles and coexist in an area of Caatinga in north-eastern Brazil, but use different foraging modes. Lizard stomachs were examined, and prey categories were quantified by frequency of occurrence, number, volume and relative importance index. We used PERMANOVA and SIMPER analyses to understand the dissimilarities among diets. Additionally, we estimated the degree of trophic niche overlap between species using the Pianka index. The most frequently consumed food item by A. ocellifera was Isoptera and Formicidae (Hymenoptera) for T. cocorobensis. The trophic niche overlap between the species was approximately 0.24 and, although there were many consumed prey categories in common, the proportion at which these prey categories were consumed was quite divergent. For example, the consumption of plant material, which was present in the diet of both species, was much more important for T. cocorobensis compared to the active forager A. ocellifera. Our results indicate that despite sharing the same space and consuming the same prey types, these species have significant differences in their diets. Furthermore, these divergences can be explained by several factors in the environment and even by the evolutionary history of each species, which are included in different families and are not evolutionarily close to each other.

Published: October 2022

Purpose. The research purpose is to increase the efficiency of borehole uranium mining by selecting special decolmating solutions and rational parameters of the technology for influencing the seam near-filter zone of geotechnological boreholes, as well as improving the filtration characteristics of the seam, depending on the mineralogical composition of ores and the structure of sediment-forming materials. Methods. The method of X-ray phase analysis was used to study the powders. The core material samples were studied on transparent sections using a LEICA DM 2500 P microscope. The content of the elemental composition of the ores and host rocks in the samples of the productive horizon was controlled using an atomic emission spectrometer. Findings. Based on the research results, quantitative-qualitative characteristics of the host rocks in the productive horizon, sedimentary formations from technological boreholes have been determined, revealing various levels in the productive horizon. It has been found that in the Campanian horizon boreholes, ores have a complex structure and multicomponent sedimentary formations, representing a mixture of sediments of mechanical-chemical origin. Originality. The results of quantitative-qualitative, microscopic, thermal research methods of the characteristics of ore-bearing rocks from various horizons at the Syr Darya depression uranium deposit have been studied and comparatively analyzed. The sedimentary formations of technological boreholes in the productive Santonian, Maastrichtian, Campanian horizons of the Northern Kharasan field, Syr Darya depression, have also been sampled and studied. The choice of the most appropriate composition of chemical reagents for dissolution and prevention of sedimentary formation in porous media has been substan-tiated by the microscopic research method. Practical implications. A detailed study and comparative analysis of the characteristics of ores and host rocks in various productive horizons makes it possible to more accurately plan the mining of blocks, minimizing emerging risks. Using the developed combined technology for intensifying borehole uranium mining, it is possible to increase the efficiency of borehole uranium mining and reduce its operating costs. At the same time, the ecological and industrial safety of the work of intensi-fying the leaching uranium ores increases.

Published: October 2022

Purpose. In safety management, near-miss incident (NMI) reporting has been recognised as an essential practice in the prevention of mining accidents. This research aims to investigate near-miss incidents in Kosovo mining operations based on previous researches and in-situ surveys. Methods. For this purpose, both qualitative and quantitative methods were used as an observation tool, with 115 questionnaires randomly assigned among the employees at mining companies. To analyse collected data, the Excel Spread-Sheet and SPSS software were used. The survey was conducted to get basic information on the number of near-miss incidents, how they occurred and were brought to the light, as well as to reveal their similarity with mining accidents that happened during mining operations in Kosovo. Findings. The research brings to the light that mining activities related to production are the most predominant sources of near-miss incidents. From the qualitative observation approach in different mining companies, it has been found that the majo-rity of mines do not report even in an informal way about near-miss incidents that the employees experience. Originality. The legislative framework of Kosovo does not require a formal reporting on near-miss incidents. Therefore, the present research aims not only to develop proper legislation, but also to comprehensively study the main factors causing near-miss incidents in order to improve mining safety. Increasing the transparency of data on near-miss incidents and their publication should facilitate research work related to improving the safety of mining operations, in other words, the prevention of mining accidents. Practical implications. Apart from the literature review and questionnaire survey conducted in two underground hard rock mines and one surface coal mine, owned and operated by Kosovo authorities, this research attempts to examine sources, influencing factors associated with near-miss incidents, as well as to analyse the best practices of NMI reporting in order to enhance mining safety management in mining sector.
Multivariate statistical-based approach to the physical-chemical behavior of shallow groundwater in a semiarid dry climate: The case study of the Gadaïne-Ain Yaghout plain NE Algeria
Authors: Dib Imane , Khedidja Abdelhamid , Chattaha Wahid , Hadji Riheb
Published: October 2022

Purpose. Several natural and anthropogenic factors control the hydro-geochemical behavior of groundwater. These factors influence on the quality, even the suitability of this resource for drinking. The main purpose of our study is the application of multivariate statistical methods to compile the mechanisms of mineralization acquisition in confined aquifers. Methods. The adopted method measures the chemical evolution of Ca+2, Mg+2, Na+, K+, HCO-3, Cl-, SO4-2, NO-3, NO-2, NH+4, and PO4-3 using an atomic-absorption spectrometer. The content of nitrogen and dissolved oxygen is measured using a spectrophotometer. Temperature (T°), electrical conductivity (EC), pH and dissolved oxygen are determined using a multi-parameter system. Findings. The main results show that 28 water samples from the Mio-Plio-Quaternary aquifer of the Gadaïne-Ain Yaghout plain have chemical facies of chloride, sulfate-calcium and chloride-magnesium types. Originality. The originality of the study is in the demonstration that water acquires its carbonate mineralization at the supply limits. Whereas it acquires its chloride, sodium and sulfate mineralization in contact with terrigenous saliferous formations, as well as in its interaction with the salt chotts formations. The results show a significant variation in the concentrations of chemical elements, in some cases exceeding drinkability standards. Mineralization is mainly caused by the dissolution of evaporitic minerals such as gypsum, halite and epsomite. Practical implications. The practical implications of this study could be resumed in terms of the convenience of multiva-riate statistical evaluation of complex physical-chemical databases in identifying pollution sources and understanding temporal variations for effective groundwater quality management in semiarid regions.
Geology, mineralogy and geochemistry of manganese ore deposits of the Um Bogma Formation, south-western Sinai, Egypt: genesis implications
Authors: El-Shafei Shaimaa , Ramadan Fatma , Essawy Mohamed , Henaish Ahmed , Nabawy Bassem
Published: October 2022

Purpose.This paper aims to understand the genesis and nature of the manganese ore deposits associated with the Ras Samra Member of the Um Bogma Formation in the southwest of Sinai. Methods. Mineralogical and geochemical studies of 50 selected samples of manganese ores and host shale have been conducted. These samples have been taken from different sites representing the Ras Samra Member. Findings. The dominant manganese minerals are pyrolusite and hausmannite. In most samples, helvite and hematite are noted in association with pyrolusite. In the investigated manganese ores, wide ranges of MnO (17.70-81.90 wt. %) and Fe2O3 (1.16-65.49 wt. %) concentrations are observed. Based on their Mn/Fe ratio, they can be classified into high-Mn ore content (76.94-6.46%), medium-Mn ore content (4.87-2.58%), and low-Mn ore content (1.51-0.30%). Originality. The compositions of major and trace elements in Ras Samra manganese ores, together with their textures and mineralogical compositions, suggest an epigenetic hydrothermal contribution for high-Mn ores, as well as syngenetic sedimentary precipitation for medium- Mn and low-Mn ores. The epigenetic nature of the high-Mn samples may be related to a younger phase of hydrothermal activity associated with Tertiary basalt flows. Ore-bearing hypogene solutions, which penetrate the bedding planes, have impregnated and cemented non-diagenetic terrigenous sandstones and shale. Practical implications. In contrast to low-Mn ores, high-Mn and medium-Mn ores of Um Bogma are preferable for obtai-ning a significant economic effect in the production of ferromanganese alloys. However, low-Mn ores need to be processed appropriately to achieve the desired quality in order to meet the present level of manganese demand in Egypt.

Published: October 2022

Purpose.The aim of the study is to develop recommendations for reducing the probability of accidents during the transportation of rock by dump trucks based on the analysis of the consequences of changes in the psycho-physiological states of the driver. Methods. The study used the method of “Hazard and operability studies” and the method of “Failure Mode and Effects Analysis” including the organizational, logical and mathematical, and statistical procedures aimed at obtaining the expert assessment of hazards from professional experts based on Grabs’ criteria that affect to change the psychophysiological state of the driver while driving a dump truck, their analysis and generalization of the results in order to prepare reasonable decisions. Findings. It is established that the psychophysiological state of the driver as a manifestation of fear, anxiety, doubt, uncertainty when performing discrete work, which is associated with frequent changes in the beginning of movement and stops of the vehicle (accumulation of a large number of dump trucks, complex route plan, etc.) leads to an increase in the risk of an emergency. It is determined that the highest level of emergency occurs due to emotional manifestations, that are associated with the relationship between employees, the presence of leadership support, psychological assistance, mobbing, conflict resolution and more. Recommendations have been developed to increase the level of transportation safety through the formation of an appropriate organizational culture at the enterprise, which ultimately shapes human social behaviour. Originality. The scientific novelty lies in the establishment of the values of occupational risk of an accident while driving a dump truck by the driver, which depends not only on the probability of a dangerous event and the severity of its consequences, but also on changes in the psychophysiological state of the driver, which results from the organizational culture of occupational safety at the mining enterprise. Practical implications. Consists in the development of a procedure for qualitative assessment of the risk of an accident from the psychophysiological state of the driver during the trucking of rock in the conditions of the mining enterprise. Recommendations for improving the safety of transportation through the formation of an appropriate organizational culture of the transport process are developed. An approach of taking into account the socio-psychological climate in the organization to assess the occurrence of the incident is proposed.

Purpose. The research purpose is to develop a geomechanical model for ensuring the safety of mining operations by determining the optimal slope angles and probabilistic assessment of the stability of the open-pit walls. Methods. Three-dimensional geomechanical models for surface mining of deposits have been developed based on calculations of the stability factor (safety factor SF) of the open-pit walls in the Rocscience program to determine the rock mass stress-strain state at the end of mining using the finite element method. The geological wireframe model (GWM) has been built on the basis of the available geological sections, horizon plans and the results of the engineering-geological surveys using the Surpac geoinformation system. Findings. Strength reduction factor (SRF) has been determined taking into account the physical-mechanical properties of rocks that constitute the near-wall mass. An assessment of the stability of walls according to the selected geological sections is given, taking into account the projected contour of the Severny Katpar open-pit walls. The calculation of the projected contour stability of the open-pit walls by several different methods has revealed that the open-pit walls are generally stable. The open-pit parameters at the end of mining have been determined. Originality. For the first time, it has been determined that in the Southern and South-Western area of the Severny Katpar open-pit wall in the horizons +700…+400, there is a decrease in SF from 1.18 to 1.41 due to the predominant occurrence of siltstones and tectonic disturbances of the walls. Practical implications. The mathematical calculation results of the stability of the projected contour walls in the Severny Katpar open pit have been generalized. In addition, a geological and structural wire-frame model of the deposit has been developed, which makes it possible to ensure the safety of mining operations in the open pit.

شهدت السينما اثناء عمرها الممتد عبر نحو قرن من الزمن احداثا وتطورات سياسية مهمة، فضلا عن التطورات التقنية والفنية وكانت السينما حاضرة وشاهدة على احداث سياسية بارزة مر بها العالم قبل واثناء وبعد الحربين العالميتين الاولى والثانية وفترة الحرب الباردة وما بعده. وقد حظيت السينما اثناء النصف الاول من القرن العشرين باهتمام كبير من قبل الدول الكبرى والسياسيين فيها فضلا عن الاقبال التجاري للشركات الكبرى للاستثمار في ذلك الميدان البكر لتحقيق الارباح، وبدأت الدول الكبرى مثل الاتحاد السوفيتي (السابق) والولايات المتحدة والمانيا وايطاليا وبريطانيا وفرنسا اثناء الد الاول من القرن الماضي بالتسابق من اجل تطوير صناعتها السينمائية واستثمار الوسيلة الجديدة وتحويل بعض الاعمال الروائية الشهيرة الى افلام تخلد تراثها الحضاري والفكري، لكن الامر تعدى فيما بعد الجوانب الابداعية والادبية والفنية للصناعة السينمائية عندما بدأت تلك الدول بالسيطرة المباشرة وتقديم الدعم الحكومي لشركاتها السينمائية لتحفزيها على انتاج افلام تتناول موضوعات وقضايا تنسجم مع طبيعة المرحلة والتوجهات السياسية السائدة في تلك الاثناء اذ ان العودة الى العشريات والثلاثينيات من القرن العشرين كفيلة بايجاد تصريحات عدة لسياسيين مثل لينين وموسوليني وهتلر وغوبلز وهم يشددون على اهمية السينما والسيطرة على صناعتها، والاشارة الى خطورة الوسيلة الناشئة في تلك الميادين السياسية والدعائية والاعلامية.
التاريخ وحداثة الشعر
Authors: رضا مبارك محمد
Published: October 2022

من اهم القضايا الفكرية، التي تحظى بالعناية قضية الحداثة ، فقد شغلت الدراسين في جميع العصور.غير ان الحداثة في الشعر، كان لها العناية الخاصة في العراق وفي البلاد العربية... وليس غريبا ان يرتبط مفهوم الحداثة بالتاريخ... او ان يكون التاريخ اهم بعد من ابعادها ... ذلك لان الشعر العربي تاريخي وهو يتحرك في مساحة من الماضي وان هذا الماضي فاعل فيه، على صعيد اللغة والصورة الادبية... وحين وجد بعض الشعراء ان تغيير الشعر وتحديثه اصبح من مستلزمات التطور ومن اساسيات التحديث ، كان الوقع الثقافي لا يستجيب لتوق الشعراء ، وان اندفاعهم في الحداثة الشعرية يصطدم بقوة الموروث وتجذره في العقل والوجدان... كما ان الذوق الادبي قد بُني على اساس من الايقاع والصورة والعاطفة من الصعب تغييرها او العبث باشكالها ... لكن التغيير كان واقعاَ ودونه سوف تتوقف حركة الشعر ، ويتضاءل عطاؤها .ربما تكثر الاسئلة كثرة ملحوظة بعد الذي شهدناه من تطور القصيدة في العراق وافادتها من المنجز الخمسيني او مفارقتها له . او بعد ما شهدناه من زهو بهذا الذي طلع به السياب ونازك والبياتي... فهو عند البعض بداية لابد من تجاوزها وعبورها سريعا.وان التغيير على مستوى الشعر لا يمكن ان يكون منفصلا عن تغيير على مستوى الفكر بشكل عام او الفلسفة ، ولابد ان يكون ضمن نظام من التطور يشمل الدراسات الاجتماعية واللغوية . او تقدم على مستوى الثقافة بشكل عام، او تطور في اشكال الوعي الفردي والاجتماعي ، او تغير في النظرة الى التاريخ والى الماضي وعلاقة ذلك بالتطلع الى المستقبل.أهم النتائجهناك نزوع عراقي نحو التجديد والتحديث , في كل مناحي الحياة , ولا سيما التجديد الأدبي والشعري اذ أن دعوات الحداثة الشعرية في الخمسينات انطلقت من العراق ومن بغداد تحديداَ . ان أي مشروع للنهضة أو التغيير , ينبغي أن ينطلق من أرض العراق تحديداَ فهذه الأرض قادرة على تجديد نفسها كل حين . وهي قادرة على تبني قاعدة حقيقية للتحديث عن المستوى الفكري والاجتماعي اذ نمت وترعرعت في أرض العراق . وان أي مشروع وافد ثقافي , أو معرفي او سياسي , لايمكن فرضه عن العراق , اذا لم يجد مكاناَ أساسياَ في أرضه . وهذا لايعني انعزالاَ ورفضاَ للتفاعل مع الآخر , لكنه يعني ،أن الفكر الانساني الأصيل , يجد استجابة طبيعية في أرض احتضنت الفكرة الانسانية .. فالعراق أرض رعت القوانين وتفاعلت مع الفكر في أجلى صورة , في دورات حضارتها المختلفة فالأفكار الأساسية في الحرية والديمقراطية وحقوق الانسان لابد أن تجد لها أساساَ ومتسعاَ في أرض رحبة كالعراق.
نظرية الصورة الذهنية واشكالية العلاقة مع التنميط
Authors: مجيد الصفار زينة عبدالستار
Published: October 2022

يقول ولترليبمان (الانسان بالتدريج يصنع لنفسة او داخل ذهنة صورا يمكن الاعتماد عليها عن العالم الذي لانستطيع الوصول اليه) وهذا يعني بأن الصورة سواء اكانت سلبية ام ايجابية فهي لاتحدث هباءا بل لاهداف قصدية فبعض المستشرقين يصدرون احكامهم حتى قبل وصولهم الى المكان المعنيين بدراسته.والصورة الذهنية تعد من اكثر المصطلحات التي اسيء استخدامها مع ان العالم اليوم اصبح عالم الصورة اذ اندثرت النظريات التي كانت تعتبر الاعلام مراة عاكسة للمجتمع بل الواقع يؤكد ان وسائل الاعلام تخلق واقعا مغايرا بل واحيانا مختلفا تماما عن الواقع، فصورة الاخر ليست هي الاخر وكذلك صورة الذات فصورة الاخر هي انعكاس لواقع العلاقة مع الذات التي انعكست في المخيلة.وهذا ما يفسر مسألة الحقيقة في الوجود هي شيء غير موجود، او كما يقال المعنى في قلب الشاعر وهنا نحن لانحاول ايجاد الحقيقة بل نؤكد على ضرورة الايمان باختلاف الايديولوجيات والا لما تعددت الاديان والافكار وانقسم الرأي العام الى مؤيد ومعارض، الامر الذي يستحق القول إن الصورة الذهنية اصبحت نظرية او علما قائما بذاتة لانها تدرس ماهو موجود وليس ماهو مفروض .ويمتاز هذا البحث بتنوع مجالاتة المعرفية من السايكولوجية والسوسيولوجية والفلسفية والاعلامية .كما ويهدف البحث الى دراسة مفهوم الصورة الذهنية ومتابعة نشأتها وارتباطاتها او تباينها عن مختلف المفاهيم والعمليات المعرفية الاخرى.كما ويهدف البحث الى دراسة مفهوم الصورة الذهنية ومتابعة نشأتها وارتباطاتها او تباينها عن مختلف المفاهيم والعمليات المعرفية الاخرى
Global Weak Solution, Uniqueness and Exponential Decay for a Class of Degenerate Hyperbolic Equation
Authors: PEREİRA Ducival , RAPOSO Carlos
Published: October 2022

This paper deals with existence, uniqueness and energy decay of solutions to a degenerate hyperbolic equations given by
\begin{align*}
K(x,t)u'' - M\left(\int_\Omega |\nabla u|^2\,dx \right) \Delta u - \Delta u' = 0,
\end{align*}
with operator coefficient $K(x,t)$ satisfying suitable properties and $M(\,\cdot \,) \in C^1([0, \infty))$ is a function which greatest lower bound for $ M (\,\cdot\,) $ is zero. For global weak solution and uniqueness we use the Faedo-Galerkin method. Exponential decay is proven by using a theorem due to M. Nakao.
Grief and the Emotion
Authors: Ben-Ze’ev Aaron
Published: October 2022

Cholbi suggests three unique features of grief which are “unlike most emotional conditions”: (1) grief is a concatenation of affective states rather than a single such state, (2) grief is not a perception-like state but a form of affectively-laden attention directed at its object, and (3) grief is an activity with an inchoate aim. While I essentially accept this characterization, I believe that these arguments are not unique to grief but common to all (or at least most) emotions.
Dispositive principle in civil proceedings: the evolution of views and modern understanding
Authors: Tymchenko Hennadiy
Published: October 2022

The research of the historical and legal context of dispositive principle in civil proceedings is given. It is noted that certain elements of dispositiveness originate from the ancient Kyiv Rus litigation process. The strengthening of government, publicity, the long-standing predominance of the investigative model of justice, frequent changes in legislation and its contradictions led to the fact that the ideas of dispositive principle, which express freedom of choice, received the greatest legislative embodiment only in the Civil Procedure Statutes of 1864 and 1895. It was during this period that the domestic science of justice began to take its formulation, which was infl uenced by
Western European procedural schools and traditions. Thus, domestic scholars have developed the doctrine of recognizing dispositiveness as an independent, separate from adversarial, principle of justice. Changes in the state system led to attempts to fi ll the dispositive principle in new content, which could be diff erent from the classical theory of order. This justifi ed and refl ected the dual basis of dispositiveness in the Soviet judiciary that was established in several codifi cations of legislation and which was about the initiative of the parties in combination with the activity of the court, prosecutor’s offi ce and other state and public organizations.
Analysing the legacy of procedural scholars and the approaches proposed today to understand the phenomenon which are considering, it should be noted the growing trend back to pre-revolutionary theory of order. At the same time, there are still some lacks its shortcomings in terms of terminology and content.
The author’s view and the concept of dispositive principle formulated in the article are based on the following features: the ability of interested person to choose diff erent actions, the willpower of the person on whom the origin and movement of the process depend; interest, which is the main factor in choosing behaviour; administrative powers of the parties; restriction of willpower, interest and behaviour if it is necessary.

Key words: civil proceedings, dispositive principle, administrative rights of the parties, adversarial proceedings, judicial reform.
